                          HOSPITALITY PROPERTIES TRUST

                             ARTICLES SUPPLEMENTARY


         HOSPITALITY  PROPERTIES TRUST, a Maryland real estate investment trust,
having its principal office in Baltimore City, Maryland  (hereinafter called the
"Trust"),  hereby  certifies to the State Department of Assessments and Taxation
of Maryland that:

         FIRST:  Pursuant to authority expressly vested in the Board of Trustees
by Article V,  Section 5.1 of the Amended and Restated  Declaration  of Trust of
the Trust, dated August 21, 1995, as amended, (the "Declaration"),  the Board of
Trustees has duly reclassified 1,000,000 unissued Preferred Shares, of the Trust
(from among the 100,000,000  Preferred  Shares,  without par value, of the Trust
which are authorized) into 1,000,000 Junior Participating  Preferred Shares, par
value $.01 per share, of the Trust.

         SECOND: The terms (including  preferences,  conversion or other rights,
voting powers,  restrictions,  limitations as to dividends,  qualifications,  or
terms or conditions of redemption) of the Junior Participating Preferred Shares,
par value $.01 per share, are as follows:

         1.  Designation  and  Amount.  The  shares  of  such  series  shall  be
designated as "Junior  Participating  Preferred Shares" and the number of shares
constituting such series shall be 1,000,000.

         2. Dividends and Distributions.

                  (a) Subject to the prior and superior rights of the holders of
         any shares of any series of Preferred Shares ranking prior and superior
         to the Junior Participating  Preferred Shares with respect to dividends
         (if any), the holders of Junior Participating Preferred Shares shall be
         entitled to receive, when, as and if declared by the Board out of funds
         legally available for the purpose,  quarterly dividends payable in cash
         on the 15th day of March,  June,  September  and  December in each year
         (each  such date  being  referred  to herein as a  "Quarterly  Dividend
         Payment Date"), commencing on the first Quarterly Dividend Payment Date
         after the first issuance of a Junior  Participating  Preferred Share or
         fraction thereof,  in an amount per share (rounded to the nearest cent)
         equal to the  greater  of (X) $5 or (Y)  subject to the  provision  for
         adjustment  hereinafter  set forth,  100 times the  aggregate per share
         amount of all cash  dividends,  plus 100 times the  aggregate per share
         amount   (payable   in  kind)  of  all  noncash   dividends   or  other
         distributions,  other  than a  dividend  payable  in  common  shares of
         beneficial  interest,  par value  $.01 per  share,  of the  Trust  (the
         "Common Shares") or a subdivision of the outstanding  Common Shares (by
         reclassification  or otherwise),  declared on the Common Shares,  since
         the immediately  preceding  Quarterly  Dividend  Payment Date, or, with
         respect to the first Quarterly  Dividend  Payment Date, since the first
         issuance  of any  Junior  Participating  Preferred  Share  or  fraction
         thereof.  In the event the Trust  shall at any time after May 20,  1997
         (the "Rights Declaration Date") (i) declare any


         dividend on Common Shares payable in Common Shares,  (ii) subdivide the
         outstanding  Common  Shares or (iii)  combine  the  outstanding  Common
         Shares  into a  smaller  number of  shares,  then in each such case the
         amount to which  holders  of shares of Junior  Participating  Preferred
         Shares were entitled  immediately  prior to such event under clause (Y)
         of the preceding  sentence shall be adjusted by multiplying such amount
         by a fraction,  the  numerator of which is the number of Common  Shares
         outstanding  immediately  after such event and the denominator of which
         is the number of Common Shares that were outstanding  immediately prior
         to such event.

                  (b) The Board shall declare a dividend or  distribution on the
         Junior  Participating  Preferred  Shares as provided in  paragraph  (a)
         above  immediately  after it declares a dividend or distribution on the
         Common  Shares  (other  than a  dividend  payable  in  Common  Shares);
         provided that, in the event no dividend or distribution shall have been
         declared on the Common Shares  during the period  between any Quarterly
         Dividend  Payment  Date  and the  next  subsequent  Quarterly  Dividend
         Payment  Date,  a dividend of $5 per share on the Junior  Participating
         Preferred  Shares  shall  nevertheless  be payable  on such  subsequent
         Quarterly Dividend Payment Date.

                  (c)  Dividends  shall  begin to accrue  and be  cumulative  on
         outstanding  Junior  Participating  Preferred Shares from the Quarterly
         Dividend  Payment Date next  preceding the date of issue of such Junior
         Participating  Preferred Shares unless the date of issue of such shares
         is prior to the record date for the first  Quarterly  Dividend  Payment
         Date, in which case dividends on such shares shall begin to accrue from
         the date of  issue of such  shares,  or  unless  the date of issue is a
         Quarterly  Dividend Payment Date or is a date after the record date for
         the determination of holders of Junior  Participating  Preferred Shares
         entitled to receive a  quarterly  dividend  and before  such  Quarterly
         Dividend  Payment Date, in either of which events such dividends  shall
         begin to accrue and be cumulative from such Quarterly  Dividend Payment
         Date.  Accrued but unpaid dividends shall not bear interest.  Dividends
         paid on the Junior  Participating  Preferred  Shares in an amount  less
         than the total amount of such dividends at the time accrued and payable
         on such shares shall be allocated  pro rata on a  share-by-share  basis
         among  all such  shares  at the time  outstanding.  The Board may fix a
         record date for the  determination  of holders of Junior  Participating
         Preferred   Shares  entitled  to  receive  payment  of  a  dividend  or
         distribution declared thereon, which record date shall be not less than
         10 and not more than 60 days  prior to the date  fixed for the  payment
         thereof.

         3. Voting Rights. The holders of Junior Participating  Preferred Shares
shall have the following voting rights:

                  (a) Subject to the provision for  adjustment  hereinafter  set
         forth,  each Junior  Participating  Preferred  Share shall  entitle the
         holder  thereof to 100 votes on all matters  submitted to a vote of the
         shareholders  of the Trust.  In the event  that the Board  shall at any
         time after the Rights  Declaration  Date (i)  declare  any  dividend on
         Common Shares payable in Common Shares,  (ii) subdivide the outstanding
         Common  Shares or (iii)  combine the  outstanding  Common Shares into a
         smaller  number of  shares,  then in each such case the number of votes
         per share to which  holders of Junior  Participating  Preferred  Shares
         were  entitled  immediately  prior to such event  shall be  adjusted by
         multiplying such number by a


                                       -2-

         fraction  the  numerator  of  which  is the  number  of  Common  Shares
         outstanding  immediately  after such event and the denominator of which
         is the number of Common Shares that were outstanding  immediately prior
         to such event.

                  (b) Except as otherwise provided herein or by law, the holders
         of Junior  Participating  Preferred  Shares  and the  holders of Common
         Shares shall vote  together as one class on all matters  submitted to a
         vote of shareholders of the Trust.

                  (c)  

                  (i)      If at any time dividends on any Junior  Participating
                           Preferred  Shares  shall be in  arrears  in an amount
                           equal to six (6)  quarterly  dividends  thereon,  the
                           occurrence  of  such   contingency   shall  mark  the
                           beginning  of a period  (a  "Default  Period")  which
                           shall  extend  until such time when all  accrued  and
                           unpaid dividends for all previous  quarterly dividend
                           periods and for the current quarterly dividend period
                           on all Junior  Participating  Preferred  Shares  then
                           outstanding  shall have been declared and paid or set
                           apart for payment.  During each Default  Period,  all
                           holders of Preferred Shares (including holders of the
                           Junior Participating Preferred Shares) with dividends
                           in  arrears in an amount  equal to six (6)  quarterly
                           dividends thereon, voting as a class, irrespective of
                           series,  shall  have  the  right  to  elect  two  (2)
                           Trustees.

                  (ii)     During any Default  Period,  such voting right of the
                           holders of Junior Participating  Preferred Shares may
                           be exercised  initially at a special  meeting  called
                           pursuant to  subparagraph  (iii) of this Section 3(c)
                           or  at  an  annual  meeting  of   shareholders,   and
                           thereafter  at  annual   meetings  of   shareholders,
                           provided that neither such voting right nor the right
                           of the  holders  of any  other  series  of  Preferred
                           Shares,  if any, to increase,  in certain cases,  the
                           authorized  number  of  Trustees  shall be  exercised
                           unless the holders of ten percent  (10%) in number of
                           Preferred  Shares  outstanding  shall be  present  in
                           person or by proxy.  The  absence  of a quorum of the
                           holders  of  Common   Shares  shall  not  affect  the
                           exercise by the holders of  Preferred  Shares of such
                           voting right.  At any meeting at which the holders of
                           Preferred  Shares  shall  exercise  such voting right
                           initially  during an existing  Default  Period,  they
                           shall  have the  right,  voting as a class,  to elect
                           Trustees to fill up to two (2) vacancies,  if any, in
                           the Board or, if such right is exercised at an annual
                           meeting,  to elect two (2)  Trustees.  The holders of
                           Preferred  Shares  shall  have the right to make such
                           increase  in the  number  of  Trustees  as  shall  be
                           necessary  to  permit  the  election  by  them at any
                           special  meeting  of  two  (2)  Trustees.  After  the
                           holders of  Preferred  Shares  shall  have  exercised
                           their right to elect  Trustees in any Default  Period
                           and during the continuance of such period, the number
                           of  Trustees  shall  not be  increased  or  decreased
                           except by vote of the holders of Preferred  Shares as
                           herein provided or

                                       -3-


                           pursuant  to  the  rights  of any  equity  securities
                           ranking  senior  to or pari  passu  with  the  Junior
                           Participating Preferred Shares, if any.

                  (iii)    Unless the holders of Preferred Shares shall,  during
                           an existing Default Period, have previously exercised
                           their right to elect  Trustees,  the Board may order,
                           or any  shareholder  or  shareholders  owning  in the
                           aggregate  not  less  than ten  percent  (10%) of the
                           total   number  of  Preferred   Shares   outstanding,
                           irrespective of series, may request, the calling of a
                           special  meeting of the holders of Preferred  Shares,
                           which meeting shall  thereupon be called by the Board
                           or the Chief  Operating  Officer  of the  Trust.  The
                           Secretary  of the  Trust  shall  give  notice of such
                           meeting and of any annual meeting at which holders of
                           Preferred  Shares are  entitled  to vote  pursuant to
                           this  paragraph  (c)(iii) to each holder of record of
                           Preferred  Shares by mailing a copy of such notice to
                           him at his last  address  as the same  appears on the
                           books of the Trust.  Such meeting shall be called for
                           a time not  earlier  than  fifteen  (15) days and not
                           later  than  sixty  (60)  days  after  such  order or
                           request.  If such meeting is not called  within sixty
                           (60) days after such order or request,  such  meeting
                           may be called on similar notice by any shareholder or
                           shareholders  owning in the  aggregate  not less than
                           ten percent  (10%) of the total  number of  Preferred
                           Shares outstanding. Notwithstanding the provisions of
                           this  paragraph  (c)(iii),  no such  special  meeting
                           shall be called  during the period  within sixty (60)
                           days  immediately  preceding  the date  fixed for the
                           next annual meeting of the shareholders.

                  (iv)     In any Default Period,  the holders of Common Shares,
                           and  (if  applicable)  other  classes  of  Shares  of
                           beneficial  interest  of the Trust (all Trust  shares
                           being referred to as "Shares"),  shall continue to be
                           entitled to elect the whole number of Trustees  until
                           the holders of Preferred  Shares shall have exercised
                           their  rights to elect two (2)  Trustees  voting as a
                           class,  after the  exercise of which  right,  (X) the
                           Trustees  so  elected  by the  holders  of  Preferred
                           Shares   shall   continue   in  office   until  their
                           successors shall have been elected by such holders or
                           until the expiration of the Default  Period,  and (Y)
                           any vacancy in the Board shall (except as provided in
                           paragraph  (c)(ii)  of this  Section  3) be filled by
                           vote  of  a  majority  of  the   remaining   Trustees
                           theretofore  elected  by the  holders of the class or
                           classes of Shares  which  elected the  Trustee  whose
                           office shall have become  vacant.  References in this
                           paragraph (c) to Trustees elected by the holders of a
                           particular  class of Shares  shall  include  Trustees
                           elected  by  such  Trustees  to  fill   vacancies  as
                           provided in clause (Y) of the foregoing sentence.

                                       -4-

                  (v)      Immediately  upon the expiration of a Default Period,
                           (X) the right of the holders of Preferred Shares as a
                           class to elect Trustees shall cease,  (Y) the term of
                           any  Trustees  elected by the  holders  of  Preferred
                           Shares as a class shall terminate, and (Z) the number
                           of  Trustees  shall be such number as may be provided
                           for in the Declaration,  any Article Supplementary or
                           the  By-Laws  of  the  Trust,   irrespective  of  any
                           increase made pursuant to the provisions of paragraph
                           (c)(ii) of this Section 3 such number being  subject,
                           however,  to change thereafter in any manner provided
                           by  law,   or  in  the   Declaration,   any   Article
                           Supplementary  or  the  By-Laws  of the  Trust).  Any
                           vacancies in the Board  effected by the provisions of
                           clauses (Y) and (Z) in the preceding  sentence may be
                           filled by a majority of the remaining Trustees.

                  (d)   Except  as  set   forth   herein,   holders   of  Junior
         Participating  Preferred Shares shall have no special voting rights and
         their  consent  shall not be  required  (except to the extent  they are
         entitled to vote with holders of Common Shares as set forth herein) for
         taking any trust action.

         4.       Certain Restrictions.

                  (a)  Whenever  quarterly   dividends  or  other  dividends  or
         distributions  payable on the Junior Participating  Preferred Shares as
         provided in Section 2 are in arrears,  thereafter and until all accrued
         and unpaid  dividends and  distributions,  whether or not declared,  on
         Junior Participating  Preferred Shares outstanding shall have been paid
         in full, the Trust shall not:

                  (i)      declare  or  pay   dividends   on,   make  any  other
                           distributions  on, or redeem or purchase or otherwise
                           acquire for  consideration  any Shares ranking junior
                           (either  as  to   dividends   or  upon   liquidation,
                           dissolution    or   winding   up)   to   the   Junior
                           Participating Preferred Shares;

                  (ii)     declare  or  pay  dividends  on  or  make  any  other
                           distributions  on  any  Shares  ranking  on a  parity
                           (either  as  to   dividends   or  upon   liquidation,
                           dissolution   or   winding   up)  with   the   Junior
                           Participating  Preferred Shares except dividends paid
                           ratably on the Junior Participating  Preferred Shares
                           and all such  parity  Shares on which  dividends  are
                           payable  or in  arrears  in  proportion  to the total
                           amounts to which the  holders of all such  Shares are
                           then entitled;

                  (iii)    redeem  or   purchase   or   otherwise   acquire  for
                           consideration  Shares  ranking on a parity (either as
                           to  dividends  or upon  liquidation,  dissolution  or
                           winding up) with the Junior  Participating  Preferred
                           Shares  provided  that  the  Trust  may at  any  time
                           redeem, purchase or otherwise acquire any such parity
                           Shares in  exchange  for any  Shares  ranking  junior
                           (either as to

                                       -5-

                           dividends or upon dissolution, liquidation or winding
                           up) to the Junior Participating Preferred Shares;

                  (iv)     purchase or otherwise  acquire for  consideration any
                           Junior Participating  Preferred Shares, or any Shares
                           ranking  on a parity  with the  Junior  Participating
                           Preferred Shares,  except pursuant to Section 8 or in
                           accordance  with a purchase  offer made in writing or
                           by  publication  (as  determined by the Board) to all
                           holders of such  shares upon such terms as the Board,
                           after consideration of the respective annual dividend
                           rates and other  relative  rights and  preferences of
                           the respective series and classes, shall determine in
                           good  faith  will   result  in  fair  and   equitable
                           treatment among the respective series or classes.

                  (b) The Trust shall not permit any  subsidiary of the Trust to
         purchase or otherwise acquire for consideration any Shares of the Trust
         unless the Trust could, under paragraph (a) of this Section 4, purchase
         or otherwise acquire such shares at such time and in such manner.

         5.  Required  Shares.  Any  Junior   Participating   Preferred  Shares,
purchased or otherwise  acquired by the Trust in any manner  whatsoever shall be
retired and cancelled  promptly after the acquisition  thereof.  All such shares
shall upon their  cancellation  become authorized but unissued  Preferred Shares
and may be reissued as part of a new series of Preferred Shares to be created by
resolution  or  resolutions  of  the  Board,   subject  to  the  conditions  and
restrictions on issuance set forth herein.

         6. Liquidation, Dissolution or Winding Up.

                  (a) Upon any liquidation (voluntary or otherwise), dissolution
         or  winding  up of the  Trust,  no  distribution  shall  be made to the
         holders  of Shares  ranking  junior  (either  as to  dividends  or upon
         liquidation,  dissolution  or winding  up) to the Junior  Participating
         Preferred  Shares,   unless,  prior  thereto,  the  holders  of  Junior
         Participating  Preferred  Shares shall have received $100.00 per share,
         plus an amount equal to accrued and unpaid dividends and  distributions
         thereon,  whether or not  declared,  to the date of such  payment  (the
         "Liquidation Preference").  Following the payment of the full amount of
         the Liquidation Preference,  no additional  distributions shall be made
         to the holders of Junior Participating  Preferred Shares, unless, prior
         thereto, the holders of Common Shares shall have received an amount per
         share (the  "Common  Adjustment")  equal to the  quotient  obtained  by
         dividing (i) the Liquidation  Preference by (ii) 100 (as  appropriately
         adjusted as set forth in subparagraph  (c) below to reflect such events
         as stock splits, stock dividends and  recapitalization  with respect to
         the Common Shares) (such number in clause (ii) immediately  above being
         referred to as the "Adjustment  Number").  Subject to the rights of any
         other series of Preferred Shares then  outstanding,  if any,  following
         the payment of the full amount of the  Liquidation  Preference  and the
         Common  Adjustment  in  respect  of all  outstanding  shares  of Junior
         Participating Preferred Shares and Common Shares, respectively, holders
         of Junior  Participating  Preferred  Shares  and  holders  of shares of
         Common Shares shall receive  their ratable and  proportionate  share of
         the remaining assets to be distributed in the

                                       -6-


         ratio of the  Adjustment  Number to one (1) with respect to such Junior
         Participating Preferred Shares and Common Shares, on a per Share basis,
         respectively.

                  (b) In the  event,  however,  that  there  are not  sufficient
         assets   available  to  permit  payment  in  full  of  the  Liquidation
         Preference  and the  liquidation  preferences  of all  other  series of
         Preferred  Shares,  if any,  which  rank on a parity  with  the  Junior
         Participating  Preferred  Shares,  then such remaining  assets shall be
         distributed ratably to the holders of such parity Shares (including the
         Junior   Participating   Preferred   Shares)  in  proportion  to  their
         respective liquidation  preferences.  In the event, however, that there
         are not  sufficient  assets  available to permit payment in full of the
         Common Adjustment after satisfaction of the liquidation  preferences of
         all series of Preferred  Shares,  if any,  then such  remaining  assets
         shall be distributed ratably to the holders of Common Shares.

                  (c) In the event the Trust  shall at any time after the Rights
         Declaration  Date (i) declare any dividend on Common Shares  payable in
         Common Shares,  (ii) subdivide the  outstanding  Common Shares or (iii)
         combine the outstanding  Common Shares into a smaller number of shares,
         then in each such  case the  Adjustment  Number  in effect  immediately
         prior to such event shall be adjusted by  multiplying  such  Adjustment
         Number by a  fraction  the  numerator  of which is the number of Common
         Shares outstanding  immediately after such event and the denominator of
         which is the number of shares of Common  Shares  that were  outstanding
         immediately prior to such event.

         7.  Consolidation,  Merger, etc. In case the Trust shall enter into any
consolidation,  merger,  combination  or other  transaction  in which the Common
Shares are exchanged for or changed into other stock or securities,  cash or any
other property,  then in any such case the Junior Participating Preferred Shares
shall at the same time be similarly  exchanged or changed in an amount per share
(subject to the provision  for  adjustment  hereinafter  set forth) equal to 100
times the aggregate  amount of shares,  securities,  cash or any other  property
(payable in kind), as the case may be, into which or for which each Common Share
is  changed  or  exchanged.  In the event the Trust  shall at any time after the
Rights  Declaration  Date (i) declare any dividend on Common  Shares  payable in
Common Shares, (ii) subdivide the outstanding Common Shares or (iii) combine the
outstanding  Common  Shares into a smaller  number of Shares,  then in each such
case the amount set forth in the preceding sentence with respect to the exchange
or  change  of  Junior  Participating  Preferred  Shares  shall be  adjusted  by
multiplying  such amount by a fraction  the  numerator of which is the number of
Common Shares  outstanding  immediately  after such event and the denominator of
which is the number of Common Shares that were outstanding  immediately prior to
such event.

         8. Redemption.  The Junior Participating  Preferred Shares shall not be
redeemable.

         9. Ranking. The Junior Participating Preferred Shares shall rank junior
to all other  series  of the  Trust's  Preferred  Shares  as to the  payment  of
dividends and the  distribution  of assets,  unless the terms of any such series
shall provide otherwise.

         10. Amendment.  At such time as Junior  Participating  Preferred Shares
are  outstanding,  the  Declaration  shall not be amended,  nor shall an Article
Supplementary  of the  Trust be filed or  amended,  in any  manner  which  would
materially alter or change the powers, preferences or special

                                       -7-

rights  of the  Junior  Participating  Preferred  Shares  so as to  affect  them
adversely  without the affirmative  vote of the holders of a majority or more of
the outstanding  Junior  Participating  Preferred Shares voting  separately as a
class.

         11. Fractional  Shares.  Junior  Participating  Preferred Shares may be
issued in fractions of a share which shall entitle the holder,  in proportion to
such holder's  fractional shares, to exercise voting rights,  receive dividends,
participate  in  distributions  and have the  benefit  of all other  rights of a
holder of Junior participating Preferred Shares.

Articles  Supplementary to be signed in its name and on its behalf by a majority
of its entire Board of Trustees and witnessed by its Secretary on May 28, 1997.
