(rounded to the nearest month)  corresponding  to the remaining life to maturity
(which,  the case of maturities  corresponding to the principal and interest due
on the notes at their  maturity,  shall be deemed to be January 15, 2012), as of
the payment date of the principal being redeemed or paid. If no maturity exactly
corresponds  to such  maturity,  yields for the two  published  maturities  most
closely  corresponding  to such  maturity  shall be  calculated  pursuant to the
immediately  preceding  sentence and the Reinvestment Rate shall be interpolated
or extrapolated from such yields on a straight-line  basis,  rounding in each of
such relevant  periods to the nearest  month.  For purposes of  calculating  the
Reinvestment  Rate, the most recent  Statistical  Release published prior to the
date of determination of the Make-Whole Amount shall be used.

definition,  "voting equity  securities"  means equity  securities having voting
power for the election of directors,  whether at all times or only so long as no
senior class of security has such voting power by reason of any contingency.

         "Total  Assets" as of any date  means the sum of (i) the  Undepreciated
Real Estate Assets and (ii) all other assets of the Company and its Subsidiaries
determined  in  accordance  with GAAP (but  excluding  accounts  receivable  and

         If DTC is at any time  unwilling,  unable or  ineligible to continue as
depositary and a successor  depositary is not appointed by the Company within 90
days, the Company will issue individual Notes in exchange for the Global Note or
Global Notes  representing such Notes. In addition,  the Company may at any time
and in its sole  discretion,  subject  to certain  limitations  set forth in the
Indenture,  determine not to have any of such Notes  represented  by one or more
Global Notes and, in such event, will issue individual Notes in exchange for the

close of  business  on the  date 14  calendar  days  immediately  preceding  the

                              ADDITIONAL COVENANTS

Article Ten of the Indenture, for the benefit of the holders of the Notes:

         (a)  Limitations on Incurrence of Debt.

         (i) The Company will not, and will not permit any  Subsidiary to, incur
any  Debt  if,  immediately  after  giving  effect  to the  incurrence  of  such
additional  Debt and the  application  of the proceeds  thereof,  the  aggregate
principal  amount of all outstanding Debt of the Company and

                                       6
<PAGE>

its  Subsidiaries on a consolidated  basis determined in accordance with GAAP is
greater than 60% of the sum ("Adjusted  Total Assets") of (without  duplication)
(i) the Total  Assets of the Company and its  Subsidiaries  as of the end of the
calendar  quarter  covered in the  Company's  Annual Report on Form 10-K, or the
Quarterly  Report on Form 10-Q, as the case may be, most recently filed with the
Securities and Exchange  Commission  (or, if such filing is not permitted  under
the Securities  Exchange Act of 1934, as amended (the "Exchange Act"),  with the
Trustee) prior to the incurrence of such  additional  Debt and (ii) the purchase
price of any real estate assets or mortgages receivable acquired, and the amount
of any securities  offering  proceeds received (to the extent that such proceeds
were not used to acquire real estate  assets or mortgages  receivable or used to
reduce Debt),  by the Company or any  Subsidiary  since the end of such calendar
quarter,  including those proceeds obtained in connection with the incurrence of
such additional Debt.

         (ii) In addition to the  foregoing  limitations  on the  incurrence  of
Debt,  the Company  will not, and will not permit any  Subsidiary  to, incur any
Secured Debt if,  immediately  after  giving  effect to the  incurrence  of such
additional  Secured  Debt  and the  application  of the  proceeds  thereof,  the
aggregate  principal  amount of all outstanding  Secured Debt of the Company and
its  Subsidiaries on a consolidated  basis is greater than 40% of Adjusted Total
Assets.

         (iii) In addition to the  foregoing  limitations  on the  incurrence of
Debt,  the Company  will not, and will not permit any  Subsidiary  to, incur any
Debt if the ratio of  Consolidated  Income  Available  for Debt  Service  to the
Annual Debt Service for the four consecutive fiscal quarters most recently ended
prior to the date on which such  additional  Debt is to be  incurred  shall have
been less than 1.5x, on a pro forma basis after giving effect thereto and to the
application of the proceeds therefrom, and calculated on the assumption that (i)
such Debt and any other Debt incurred by the Company and its Subsidiaries  since
the first day of such  four-quarter  period and the  application of the proceeds
therefrom,  including to refinance  other Debt, had occurred at the beginning of
such period;  (ii) the  repayment or retirement of any other Debt by the Company
and its Subsidiaries  since the first date of such four-quarter  period had been
repaid or retired at the  beginning of such period  (except that, in making such
computation,  the amount of Debt under any revolving  credit  facility  shall be
computed  based upon the average daily balance of such Debt during such period);
(iii) in the case of  Acquired  Debt or Debt  incurred  in  connection  with any
acquisition  since  the  first  day of such  four-quarter  period,  the  related
acquisition  had  occurred as of the first day of such  period with  appropriate
adjustments  with respect to such  acquisition  being included in such pro forma
calculation;  and  (iv) in the case of any  acquisition  or  disposition  by the
Company or its  Subsidiaries of any asset or group of assets since the first day
of such four-quarter period, whether by merger, stock purchase or sale, or asset
purchase or sale,  such  acquisition or disposition or any related  repayment of
Debt had  occurred  as of the  first  day of such  period  with the  appropriate
adjustments  with respect to such  acquisition or disposition  being included in
such pro  forma  calculation.  If the Debt  giving  rise to the need to make the
foregoing  calculation  or any other  Debt  incurred  after the first day of the
relevant  four-quarter  period  bears  interest  at a floating  rate  then,  for
purposes of calculating the Annual Debt Service,  the interest rate on such Debt
shall be computed on a pro forma  basis as if the  average  interest  rate which
would have been in effect  during the entire such  four-quarter  period had been
the applicable rate for the entire such period.

                                       7
<PAGE>

         (b)  Maintenance  of Total  Unencumbered  Assets.  The  Company and its
Subsidiaries  will maintain at all times Total  Unencumbered  Assets of not less
than 200% of the aggregate outstanding principal amount of the Unsecured Debt of
the Company and its Subsidiaries on a consolidated basis.

after there shall have been given,  by  registered  or  certified  mail,  to the

             [THE FOLLOWING CONSTITUTES THE REVERSE OF THE SECURITY]

                          HOSPITALITY PROPERTIES TRUST

                           6.85% Senior Notes due 2012

         Capitalized terms used herein have the meanings assigned to them in the
Indenture (as defined below) unless otherwise indicated.

         1.  Interest.  Hospitality  Properties  Trust,  a Maryland  real estate
investment  trust (the  "Company"),  promises to pay  interest on the  principal
amount of this Note at the rate and in the manner specified below.

         The Company shall pay in cash interest on the principal  amount of this
Note at the rate per annum of 6.85%. The Company will pay interest semi-annually
in arrears on January  15 and July 15 of each year,  commencing  on January  15,
2003 or if any such day is not a Business Day (as defined in the Indenture),  on
the next succeeding  Business Day (each an "Interest  Payment Date"), to Holders
of record on the immediately preceding January 1 and July 1.

         Interest will be computed on the basis of a 360-day year  consisting of
twelve 30-day  months.  Interest shall accrue from the most recent date to which
interest  has been paid or, if no interest  has been paid,  from the date of the
original issuance of the Notes.

         2.  Method of  Payment.  The  Company  will pay  interest  on the Notes
(except defaulted  interest) to the Persons who are registered  Holders of Notes
at the close of business on the record date next preceding the Interest  Payment
Date,  even if such Notes are  canceled  after such record date and on or before
such Interest Payment Date. The Company will pay principal and interest in money
of the United  States that at the time of payment is legal tender for payment of
public and private debts. The Company,  however, may pay principal,  premium, if
any, and interest by check payable in such money.  It may mail an interest check
to a Holder's registered address.

         3. Indenture.  The Company issued the Notes under an Indenture dated as
of February 25, 1998 and  Supplemental  Indenture No. 6 dated as of July 8, 2002
(collectively,  the "Indenture")  between the Company and the Trustee. The terms
of the Notes  include  those stated in the  Indenture and those made part of the
Indenture by reference to the Trust  Indenture  Act of 1939 (15 U.S. Code ss.ss.
77aaa-77bbbb)  as in effect on the date of the Indenture.  The Notes are subject
to all such terms,  and Holders of the Notes are referred to the  Indenture  and
such Act for a statement of such terms.  The terms of the Indenture shall govern
any inconsistencies between the Indenture and the Notes. The Notes are unsecured
general  obligations of the Company  initially issued in an aggregate  principal
amount of $125,000,000.

         4. Optional Redemption.  The Notes will be subject to redemption at any
time at the option of the  Company,  in whole or in part,  upon not less than 30
nor more than 60 days' notice, at a redemption price equal to the sum of (i) the
principal  amount of the Notes being redeemed,  plus accrued and unpaid interest
to but excluding the applicable Redemption Date and (ii) the Make-Whole Amount.

                                       A-2
<PAGE>

         As used herein the term  "Make-Whole  Amount" means, in connection with
any optional redemption or accelerated payment of any notes prior to January 15,
2012, the excess,  if any, of (i) the aggregate  present value as of the date of
such  redemption  or  accelerated  payment  of each  dollar of  principal  being
redeemed or paid and the amount of interest  (exclusive  of interest  accrued to
the date of redemption or  accelerated  payment) that would have been payable in
respect of such dollar if such  redemption or accelerated  payment had been made
on January 15, 2012,  determined by  discounting,  on a semiannual  basis,  such
principal  and  interest  at the  Reinvestment  Rate  (determined  on the  third
Business  Day  preceding  the  date  such  notice  of  redemption  is  given  or
declaration of  acceleration  is made) from the  respective  dates on which such
principal and interest would have been payable if such redemption or accelerated
payment had been made on January 15,  2012,  over (ii) the  aggregate  principal
amount of the Notes being  redeemed or paid.  In the case of any  redemption  or
accelerated payment of notes on or after January 15, 2012, the Make-Whole Amount
means zero.  For  purposes of the  Indenture  and the Notes,  references  in the
Indenture to the payment of the principal (and premium,  if any) and interest on
the Notes shall be deemed to include the payment of the  Make-Whole  Amount,  if
any, due upon redemption with respect to the Notes. The Make-Whole  Amount shall
be calculated by the Company and set forth in an Officer's Certificate delivered
to the  Trustee,  and the Trustee  shall be  entitled to rely on said  Officer's
Certificate.

         As used  herein  the term  "Reinvestment  Rate"  means a rate per annum
equal to the sum of 0.50% (fifty one  hundredths  of one percent) plus the yield
on treasury  securities  at constant  maturity  under the heading  "Week Ending"
published  in the  Statistical  Release  (as defined  herein)  under the caption
"Treasury  Constant  Maturities" for the maturity (rounded to the nearest month)
corresponding  to  the  remaining  life  to  maturity  (which,  in the  case  of
maturities corresponding to the principal and interest due on the notes at their
maturity, shall be deemed to be January 15, 2012), as of the payment date of the
principal  being  redeemed or paid. If no maturity  exactly  corresponds to such
maturity,  yields for the two published maturities most closely corresponding to
such maturity shall be calculated pursuant to the immediately preceding sentence
and the Reinvestment Rate shall be interpolated or extrapolated from such yields
on a  straight-line  basis,  rounding  in each of such  relevant  periods to the
nearest  month.  For purposes of  calculating  the  Reinvestment  Rate, the most
recent  Statistical  Release published prior to the date of determination of the
Make-Whole Amount shall be used.

         As used herein the term  "Statistical  Release"  means the  statistical
release designated  "H.15(519)" or any successor  publication which is published
weekly by the Federal  Reserve System and which  establishes  yields on actively
traded United States government  securities  adjusted to constant maturities or,
if such  statistical  release is not published at the time of any  determination
under the Supplemental Indenture,  then any publicly available source of similar
market data which shall be designated by the Company.

         5.  Mandatory  Redemption.  The  Company  shall not be required to make
sinking fund or redemption payments with respect to the Notes.

         6. Notice of Redemption.  Notice of redemption shall be mailed at least
30 days but not more than 60 days before the  Redemption  Date to each Holder of
Notes to be redeemed at its  registered  address.  Notes may be redeemed in part
but only in whole multiples of $1,000,  unless

                                       A-3
<PAGE>

all  of the  Notes  held  by a  Holder  are to be  redeemed.  On and  after  the
redemption  date,  interest ceases to accrue on Notes or portions of them called
for redemption.

         7. Denominations,  Transfer, Exchange. The Notes are in registered form
without coupons in denominations  of $1,000 and integral  multiples of $1,000 in
excess  thereof.  The  transfer  of Notes  may be  registered  and  Notes may be
exchanged as provided in the Indenture.  The Security  Registrar and the Trustee
may require a Holder,  among other things, to furnish  appropriate  endorsements
and  transfer  documents  and to pay  any  taxes  and  fees  required  by law or
permitted by the Indenture. The Security Registrar need not exchange or register
the transfer of any Note or portion of a Note selected for redemption.  Also, it
need not  exchange or register the transfer of any Notes for a period of 15 days
before the  mailing  of a notice of  redemption  of Notes,  or during the period
between a record date and the corresponding Interest Payment Date.

         8.  Defaults and  Remedies.  In case an Event of Default (as defined in
the Indenture)  with respect to the Notes shall have occurred and be continuing,
the principal hereof may be declared,  and upon such  declaration  shall become,
due and payable,  in the manner,  with the effect and subject to the  provisions
provided in the Indenture.

         9. Actions of Holders. The Indenture contains provisions permitting the
holders of not less than a majority  of the  aggregate  principal  amount of the
outstanding  Notes,  subject to certain exceptions as provided in the Indenture,
on behalf of the holders of all such Notes at a meeting  duly called and held as
provided  in  the  Indenture,  to  make,  give  or  take  any  request,  demand,
authorization,  direction,  notice,  consent, waiver or other action provided in
the Indenture to be made, given or taken by the holders of the Notes,  including
without  limitation,   waiving  (a)  compliance  by  the  Company  with  certain
provisions of the  Indenture,  and (b) certain past defaults under the Indenture
and their  consequences.  Any resolution passed or decision taken at any meeting
of the holders of the Notes in accordance  with the  provisions of the Indenture
shall be conclusive and binding upon such holders and upon all future holders of
this Note and other Notes issued upon the  registration of transfer hereof or in
exchange heretofore or in lieu hereof.

         10. Persons Deemed Owners. The Company,  the Trustee,  and any agent of
the Company or the Trustee may deem and treat the Person in whose name this Note
is registered on the Security Register as its absolute owner for all purposes.

         11. Authentication. This Note shall not be valid until authenticated by
the manual signature of the Trustee or an authenticating agent.

         12.   Governing   Law.  THE  INTERNAL  LAW  OF  THE   COMMONWEALTH   OF
MASSACHUSETTS SHALL GOVERN AND BE USED TO CONSTRUE THE INDENTURE AND THE NOTES.

         13. No Personal  Liability.  THE  DECLARATION  OF TRUST OF THE COMPANY,
AMENDED AND  RESTATED ON AUGUST 21,  1995,  A COPY OF WHICH,  TOGETHER  WITH ALL
AMENDMENTS  THERETO  (THE  "DECLARATION"),  IS DULY  FILED IN THE  OFFICE OF THE
DEPARTMENT OF ASSESSMENTS  AND TAXATION OF THE STATE OF MARYLAND,  PROVIDES THAT
