Item 1. Description of Registrant's Securities to Be Registered

         On May 20, 1997, the Board of Trustees of Hospitality  Properties Trust
(the "Company") adopted a shareholder protection rights plan. The plans provides
for the distribution of one Junior Participating  Preferred Share Purchase Right
(a "Right") for each of the Company's common shares of beneficial interest,  par
value  $.01 per share  (the  "Common  Shares").  The  initial  distribution  was
declared as a dividend for each of the  Company's  outstanding  Common Shares to
holders of record at the close of business on June 20, 1997.

         Each Right entitles the registered  holder to purchase from the Company
one one-hundredth of a Junior Participating  Preferred Share, par value $.01 per
share,  of the  Company  (the  "Junior  Participating  Preferred  Shares") or in
certain  circumstances,  to  receive  cash,  property,  Common  Shares  or other
securities of the Company,  at a purchase price (the  "Purchase  Price") of $100
per  one-hundredth  of  a  Junior  Participating  Preferred  Share,  subject  to
adjustment.  The  description  and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the Company and State Street Bank and
Trust Company, as Rights Agent.

         Initially, the Rights will be attached to all certificates representing
the Common Shares and no separate Rights  Certificates will be distributed.  The
Rights will separate from the Common Shares and a  Distribution  Date will occur
upon the  earlier of (i) 10 business  days (or such later date as the  Company's
Board of Trustees may determine before a Distribution  Date occurs)  following a
public  announcement  by the  Company  that a person or group of  affiliated  or
associated  persons,  with  certain  exceptions  (an  "Acquiring  Person"),  has
acquired,  or has obtained the right to acquire,  beneficial ownership of 10% or
more of the outstanding  Common Shares (the date of such announcement  being the
"Share  Acquisition  Date") or (ii) 10 business  days (or such later date as the
Company's  Board of Trustees may determine  before a  Distribution  Date occurs)
following the commencement of a tender offer or exchange offer that would result
in a person becoming an Acquiring Person.

         Until the  Distribution  Date,  (i) the Rights will be evidenced by the
certificates  for Common Shares and will be transferred  with and only with such
Common  Share  certificates,  (ii)  Common  Share  certificates  will  contain a
notation  incorporating  the  Rights  Agreement  by  reference,  and  (iii)  the
surrender for transfer of any  certificates  for Common Shares  outstanding will
also  constitute  the transfer of the Rights  associated  with the Common Shares
represented by such certificates.

         The Rights are not  exercisable  until the  Distribution  Date and will
expire at the close of  business on May 31,  2007,  unless  earlier  redeemed or
exchanged by the Company as described below.

         As soon as practicable after the Distribution Date, Rights Certificates
will be mailed to  holders  of  record of the  Common  Shares as of the close of
business on the Distribution Date and, from and after the Distribution Date, the
separate Rights Certificates alone will represent the Rights.


                                       -1-

<PAGE>


         In the event (a "Flip-In  Event") a Person becomes an Acquiring  Person
(except pursuant to a tender or exchange offer for all outstanding Common Shares
at a price and on terms which a majority of the Company's  Outside  Trustees (as
defined in the Rights  Agreement)  determines to be fair to and otherwise in the
best  interests  of the Company and its  shareholders  (a "fair  offer")),  each
holder of a Right will  thereafter  have the right to receive,  upon exercise of
such Right, Common Shares (or, in certain circumstances, cash, property or other
securities  of the  Company)  having a Current  Market  Price (as defined in the
Rights  Agreement)  equal to two times the  exercise  price of the  Right.  (For
example,  at the initial exercise price of $100 per Right,  each Right not owned
by an Acquiring Person (or by certain related parties) following a Flip-In Event
would  entitle  its holder to  purchase  $200  worth of Common  Shares (or other
consideration,  as  noted  above)  for  $100).  Notwithstanding  the  foregoing,
following the  occurrence of any Flip-In  Event,  all Rights that are, or (under
certain  circumstances  specified in the Rights  Agreement)  were,  beneficially
owned by any Acquiring  Person (or by certain related  parties) will be null and
void in the  circumstances set forth in the Rights  Agreement.  However,  Rights
will not be exercisable following the occurrence of any Flip-In Event until such
time as the Rights are no longer redeemable by the Company as set forth below.

         In the event (a  "Flip-Over  Event")  that, at any time on or after the
Share  Acquisition  Date,  (i) the Company  shall take part in a merger or other
business combination  transaction (other than certain mergers that follow a fair
offer) and the Company  shall not be the surviving  entity,  or (ii) the Company
shall take part in a merger or other business  combination  transaction in which
the Common  Shares are changed or  exchanged  (other than  certain  mergers that
follow a fair offer),  or (iii) 50% or more of the  Company's  assets or earning
power is sold or  transferred,  each  holder  of a Right  (except  Rights  which
previously have been voided, as set forth above) shall thereafter have the right
to receive,  upon exercise,  a number of shares of common stock of the acquiring
company  having a Current  Market Price equal to two times the exercise price of
the Right.  Flip-In Events and Flip-Over Events are collectively  referred to as
"Triggering Events."

         The  Purchase  Price  payable  and the  number of Junior  Participating
Preferred Shares (or the amount of cash, property or other securities)  issuable
upon  exercise  of the Rights are  subject  to  adjustment  from time to time to
prevent  dilution  (i) in the event of a share  dividend  on, or a  subdivision,
combination or reclassification of, the Junior  Participating  Preferred Shares,
(ii) if holders of the Junior Participating Preferred Shares are granted certain
rights or warrants to subscribe  for Junior  Participating  Preferred  Shares or
convertible  securities  at less than the  Current  Market  Price of the  Junior
Participating  Preferred Shares or (iii) upon the distribution to holders of the
Junior  Participating  Preferred  Shares of evidences of  indebtedness or assets
(excluding  regular  quarterly  cash  dividends)  or of  subscription  rights or
warrants (other than those referred to above).

         With certain  exceptions,  no adjustment in the Purchase  Price will be
required  until  cumulative  adjustments  amount to at least 1% of the  Purchase
Price.  The Company is not  required to issue  fractional  Junior  Participating
Preferred Shares upon the exercise of any Right or Rights evidenced  hereby.  In
lieu thereof, a cash payment may be made, as provided in the Rights Agreement.


                                       -2-

<PAGE>



         At any time until 10  business  days  following  the Share  Acquisition
Date, the Company may redeem the Rights in whole, but not in part, at a price of
$.01 per Right, payable, at the option of the Company, in cash, Common Shares or
other consideration as the Board of Trustees may determine. Immediately upon the
effectiveness  of the  action  of  the  Company's  Board  of  Trustees  ordering
redemption  of the Rights,  the Rights will  terminate and the only right of the
holders of Rights will be to receive the $.01 per Right redemption price.

         Until a Right is exercised,  the holder thereof,  as such, will have no
rights as a shareholder of the Company, including, without limitation, the right
to vote or to receive  dividends.  While the distribution of the Rights will not
be taxable to shareholders or to the Company,  shareholders may,  depending upon
the circumstances,  recognize taxable income in the event that the Rights become
exercisable  for Common Shares (or cash,  property or other  securities)  of the
Company or for common stock of the acquiring company as set forth above.

         The terms of the Rights, other than key financial terms and the date on
which the Rights expire,  may be amended by the Board of Trustees of the Company
prior  to the  Distribution  Date.  Thereafter,  the  provisions  of the  Rights
Agreement  may be  amended  by the Board of  Trustees  only in order to cure any
ambiguity,  defect or  inconsistency,  to make  changes  which do not  adversely
affect the  interests  of  holders of Rights  (excluding  the  interests  of any
Acquiring  Person and certain other  related  parties) or to shorten or lengthen
any time period under the Rights Agreement; provided, however, that no amendment
to lengthen the time period  governing  redemption shall be made at such time as
the Rights are not redeemable.

         In connection with adoption of the shareholder  protection rights plan,
the Trustees  established an authorized  but unissued class of 1,000,000  Junior
Participating  Preferred  Shares.  Certain  powers,  preferences  and rights and
certain qualifications, limitations and restrictions of the Junior Participating
Preferred Shares, when and if issued, are as follows.  The statements below with
respect to the Junior Participating Preferred Shares are in all respects subject
to and qualified in their entirety by reference to the applicable  provisions of
the  Company's   Declaration  of  Trust   (including  the  applicable   articles
supplementary) and By-Laws.

         The holder of each Junior Participating  Preferred Share is entitled to
quarterly  dividends in the greater  amount of $5.00 or 100 times the  quarterly
per share dividend, whether cash or otherwise,  declared upon the Common Shares.
Dividends on the Junior Participating Preferred Shares are cumulative.  Whenever
dividends  on the Junior  Participating  Preferred  Shares are in  arrears,  the
Company,  among other things,  is prohibited from declaring or paying dividends,
making other  distributions  on, or redeeming or  repurchasing  Common Shares or
other of the Company's shares of beneficial  interest  ("Shares") ranking junior
to the Junior Participating Preferred Shares, and upon failure of the Company to
pay such  dividends  for six quarters,  the holders of the Junior  Participating
Preferred  Shares  will be entitled  to elect two  Trustees.  The holder of each
Junior  Participating  Preferred  Share is  entitled to 100 votes on all matters
submitted to a vote of the shareholders,  voting (unless  otherwise  provided in
the  Declaration or by law) together with holders of Common Shares as one class.
Upon  liquidation,  dissolution  or winding up of the  Company,  the  holders of
Junior Participating  Preferred Shares are entitled to a liquidation  preference


                                       -3-

<PAGE>


of $100 per share  plus the  amount of any  accrued  and  unpaid  dividends  and
distributions  thereon (the "Liquidation  Preference"),  prior to payment of any
distribution  in respect of the Common Shares or any other Shares ranking junior
to  the  Junior  Participating  Preferred  Shares.   Following  payment  of  the
Liquidation Preference, the holders of Junior Participating Preferred Shares are
not entitled to further  distributions  until the holders of Common Shares shall
have received an amount per share (the "Common Share  Adjustment")  equal to the
Liquidation  Preference divided by 100 (adjusted to reflect events such as stock
splits, stock dividends and  recapitalizations  affected the Common Shares) (the
"Adjustment  Number").   Following  the  payment  of  the  full  amount  of  the
Liquidation  Preference  and the  Common  Share  Adjustment,  holders  of Junior
Participating Preferred Shares are entitled to participate  proportionately on a
per share  basis  with  holders  of Common  Shares  in the  distribution  of the
remaining  assets to be  distributed  in  respect  of Shares in the ratio of the
Adjustment Number to one,  respectively.  The powers,  preferences and rights of
the Junior  Participating  Preferred  Shares are subject to the superior powers,
preferences  and rights of any senior series or class of preferred  Shares which
the Trustees shall, from time to time, authorize and issue.

         This  summary  description  of the Rights or the  Junior  Participating
Preferred  Shares  does not  purport  to be  complete  and is  qualified  in its
entirety  by  reference  to the Rights  Agreement  filed as Exhibit  4.1 to this
Registration   Statement  (including  without  limitation  the  form  of  Rights
Certificate  and the  form of  Articles  Supplementary  designating  the  Junior
Participating Preferred Shares attached thereto). Capitalized terms used and not
defined herein have the meanings set forth in the Rights Agreement.

         RIGHTS  AGREEMENT,  dated  as of  May  20,  1997,  between  Hospitality

         WHEREAS, on May 20, 1997 (the "Rights Dividend  Declaration Date"), the

of one Right (as  hereinafter  defined)  for each Common  Share (as  hereinafter
defined) of the Company  outstanding  at the Close of Business  (as  hereinafter
defined) on June 20, 1997 (the "Record  Date"),  and  authorized the issuance of
one Right (as such number may hereinafter be adjusted pursuant to the provisions
of Section 11(i) hereof) for each Common Share of the Company issued between the
Record Date (whether originally issued or delivered from the Company's treasury)
and  the   Distribution   Date  (as  hereinafter   defined)  and  under  certain
circumstances  thereafter,  each  Right  initially  representing  the  right  to
purchase one one-hundredth of a Preferred Share (as hereinafter  defined) of the
Company, upon the terms and subject to the conditions hereinafter set forth (the

         NOW,  THEREFORE,  in  consideration  of the  premises  and  the  mutual
agreements herein set forth, the parties hereby agree as follows:

substantially  in the  form  attached  hereto  as  Exhibit  B (the  "Summary  of
Rights"), attached or bearing the legend set forth in Section 3(c) hereof (which
certificates  for  Common  Shares  of the  Company  shall be  deemed  also to be
certificates  for Rights) and not by  separate  certificates  and (y) the Rights
will be  transferable  only in  connection  with the transfer of the  underlying
Common Shares of the Company  (including a transfer to the Company).  As soon as
practicable  after  the  Distribution  Date,  the  Rights  Agent  will  send  by
first-class,  insured, postage prepaid mail, to each record holder of the Common
Shares of the Company as of the Close of Business on the  Distribution  Date, at

rights  certificates in substantially  the form of Exhibit C hereto (the "Rights
Certificates")  evidencing  one Right for each  Common  Share of the  Company so

                  (b) As promptly as practicable  following the Record Date, the

prepaid  mail,  to each record  holder of the Common Shares of the Company as of
the Close of Business on the Record Date, at the address of such holder shown on

of the Company  outstanding as of the Record Date, as set forth in paragraph (a)

Company  with or  without  a copy of the  Summary  of Rights  attached,  and the
registered  holders  of the  Common  Shares  of the  Company  shall  also be the
registered  holders  of  the  associated  Rights.   Until  the  earlier  of  the
Distribution  Date or the  Expiration  Date,  the  transfer of any  certificates
representing  Common  Shares of the Company in respect of which Rights have been
issued shall also  constitute  the transfer of the Rights  associated  with such

                  (c) Rights shall be issued in respect of all Common  Shares of
the Company which are issued  (whether  originally  issued or from the Company's
treasury)  after the Record  Date but prior to the  earlier of the  Distribution
Date or the Expiration Date, and to the extent provided in Section 22 hereof, in
respect of Common Shares of the Company issued after the  Distribution  Date and
prior to the Expiration Date.  Certificates  representing  such Common Shares of
the Company shall also be deemed to be  certificates  for Rights,  and shall, as
promptly as practicable following the Record Date, bear the following legend:

                  This certificate also evidences and entitles the holder hereof
         to  certain  Rights  as set  forth  in  the  Rights  Agreement  between
         Hospitality  Properties Trust (the "Company") and State Street Bank and
         Trust  Company  (the  "Rights  Agent")  dated as of May 20,  1997  (the
         "Rights Agreement"),  the terms of which are hereby incorporated herein
         by reference and a copy of which is on file at the principal offices of
         the Company.  Under certain  circumstances,  as set forth in the Rights
         Agreement,  such Rights will be evidenced by separate  certificates and
         will no longer be evidenced by this certificate.  The Company will mail
         to the holder of this certificate a copy of the Rights Agreement, as in
         effect on the date of mailing, without charge promptly after receipt of
         a written request  therefor.  Under certain  circumstances set forth in
         the  Rights  Agreement,  Rights  beneficially  owned  (as such  term is
         defined in the Rights  Agreement) by, any Person who is, was or becomes
         an Acquiring Person, or any Affiliate or Associate

                                      - 6 -

         thereof  (as such terms are defined in the Rights  Agreement),  whether
         currently  held by or on  behalf of such  Person  or by any  subsequent
         holder,  may become null and void. The Rights shall not be exercisable,
         and  shall be void so long as held,  by a  holder  in any  jurisdiction
         where the requisite  qualification  to the issuance to such holder,  or
         the exercise by such holder, of the Rights in such  jurisdiction  shall
         not have been obtained or be obtainable.

With respect to such  certificates  containing the foregoing  legend,  until the
earlier of the Distribution  Date or the Expiration Date, the Rights  associated
with the Common Shares of the Company  represented by such certificates shall be
evidenced by such certificates alone, and registered holders of Common Shares of
the Company shall also be the registered  holders of the associated  Rights, and
the transfer of any of such  certificates  shall also constitute the transfer of
the Rights associated with the Common Shares of the Company  represented by such
certificates.

printed thereon as the Company may deem  appropriate and as are not inconsistent
with the provisions of this Agreement,  or as may be required to comply with any
applicable law or with any rule or regulation made pursuant  thereto or with any
rule or  regulation  of any stock  exchange on which the Rights may from time to
time be listed, or to conform to usage.  Subject to the provisions of Section 11
and Section 22 hereof, the Rights Certificates,  whenever distributed,  shall be
dated as of the Record Date and on their face shall entitle the holders  thereof
to purchase such number of one  one-hundredths  of a Preferred Share as shall be
set forth therein at the exercise  price set forth therein (such  exercise price
per one  one-hundredth of a share, as adjusted from time to time hereunder,  the
"Purchase  Price"),  but the amount and type of securities  purchasable upon the
exercise  of each  Right and the  Purchase  Price  thereof  shall be  subject to
adjustment as provided herein.

                  (b) Any Rights  Certificate issued pursuant to Section 3(a) or
Section 22 hereof that represents Rights  beneficially owned by (i) an Acquiring
Person or any Associate or Affiliate of an Acquiring  Person,  (ii) a transferee
of an Acquiring  Person (or of any such  Associate or  Affiliate)  who becomes a
transferee  after the Acquiring  Person becomes such or (iii) a transferee of an
Acquiring  Person  (or of  any  such  Associate  or  Affiliate)  who  becomes  a
transferee prior to or concurrently  with the Acquiring Person becoming such and
receives  such  Rights  pursuant  to either (A) a transfer  (whether  or not for
consideration)  from the Acquiring Person to holders of equity interests in such
Acquiring  Person  or to any  Person  with whom such  Acquiring  Person  has any
continuing  agreement,  arrangement or  understanding  regarding the transferred
Rights  or (B) a  transfer  which a  majority  of the  Continuing  Trustees  has
determined  is part of a  plan,  arrangement  or  understanding  which  has as a
primary  purpose or effect  avoidance  of Section  7(e)  hereof,  and any Rights
Certificate  issued  pursuant to Section 6 or Section 11 hereof  upon  transfer,
exchange,  replacement or adjustment of any other Rights Certificate referred to
in this sentence, shall contain (to the extent feasible) the following legend:

         The  Rights   represented  by  this  Rights  Certificate  are  or  were
         beneficially owned by a Person who was or became an Acquiring Person or
         an Affiliate  or  Associate  of an Acquiring  Person (as such terms are
         defined in the Rights Agreement).  Accordingly, this Rights Certificate
         and the  Rights  represented  hereby  may  become  null and void in the
         circumstances specified in Section 7(e) of such Agreement.

and by the Treasurer or any Assistant Treasurer, either manually or by facsimile

Agent and shall not be valid for any purpose  unless so  countersigned.  In case
any officer of the Company who shall have signed any of the Rights  Certificates
shall cease to be such  officer of the Company  before  countersignature  by the
Rights Agent and issuance and delivery by the Company, such Rights Certificates,
nevertheless,  may be countersigned by the Rights Agent and issued and delivered
by the  Company  with the same  force and effect as though the person who signed
such Rights  Certificates had not ceased to be such officer of the Company;  and
any  Rights  Certificates  may be signed on behalf of the  Company by any person
who, at the actual date of the execution of such Rights Certificate,  shall be a
proper officer of the Company to sign such Rights  Certificate,  although at the
date of the  execution of this Rights  Agreement any such person was not such an
officer.

Date, any Rights  Certificate or Rights  Certificates may be transferred,  split
up, combined or exchanged for another Rights Certificate or Rights Certificates,
entitling the registered holder to purchase a like number of one  one-hundredths
of a Preferred Share (or,  following a Triggering  Event,  Common Shares,  other
securities,  cash or other assets, as the case may be) as the Rights Certificate
or Rights  Certificates  surrendered then entitled such holder (or former holder
in the case of a  transfer)  to  purchase.  Any  registered  holder  desiring to
transfer,  split up,  combine  or  exchange  any  Rights  Certificate  or Rights
Certificates  shall make such request in writing  delivered to the Rights Agent,
and shall  surrender the Rights  Certificate or  Certificates to be transferred,
split up, combined or exchanged at the principal office or offices of the Rights
Agent  designated  for such  purpose.  Neither the Rights  Agent nor the Company
shall be obligated to take any action whatsoever with respect to the transfer or
exchange of any such surrendered Rights Certificate or Rights Certificates until
the registered holder shall have completed and signed the certificate  contained
in the form of  assignment  on the reverse  side of such Rights  Certificate  or
Rights  Certificates  and shall have  provided such  additional  evidence of the
identity of the Beneficial Owner (or former  Beneficial  Owner) or Affiliates or
Associates thereof as the Company shall reasonably request. Thereupon the Rights
Agent  shall,  subject  to Section  4(b),  Section  7(e) and  Section 14 hereof,
countersign and deliver to the Person entitled  thereto a Rights  Certificate or
Rights  Certificates,  as the case may be,  as so  requested.  The  Company  may
require payment of a sum sufficient to cover any tax or governmental charge that
may be  imposed  in  connection  with any  transfer,  split up,  combination  or
exchange of Rights Certificates.

                  (b)  Upon  receipt  by the  Company  and the  Rights  Agent of
evidence reasonably satisfactory to each of them of the loss, theft, destruction
or  mutilation  of a valid Rights  Certificate,  and, in case of loss,  theft or
destruction,  of indemnity or security reasonably  satisfactory to each of them,
and reimbursement to the Company and the Rights Agent of all reasonable expenses
incidental  thereto,  and upon surrender to the Rights Agent and cancellation of
the Rights Certificate if mutilated,  the Company will execute and deliver a new
Rights  Certificate of like tenor to the Rights Agent for  countersignature  and
delivery  to the  registered  owner in lieu of the Rights  Certificate  so lost,
stolen, destroyed or mutilated.

         Section 7.  Exercise  of Rights;  Purchase  Price:  Expiration  Date of
Rights.

                  (a) Subject to Section 7(e) hereof,  the registered  holder of
any Rights  Certificate  may exercise the Rights  evidenced  thereby  (except as
otherwise  provided herein including,  without  limitation,  the restrictions on
exercisability  set forth in Section 9(c),  Section 11(a)(iii) and Section 23(a)
hereof)  in  whole or in part at any  time  after  the  Distribution  Date  upon
surrender of the Rights  Certificate,  with the form of election to purchase and
the  certificate on the reverse side thereof duly executed,  to the Rights Agent
at the  principal  office or  offices of the Rights  Agent  designated  for such
purpose,  together with payment of the aggregate  Purchase Price with respect to
the total number of one  one-hundredths  of a Preferred Share (or Common Shares,
other  securities,  cash or other  assets,  as the case may be) as to which such
surrendered Rights are then exercisable,  at or prior to the earliest of (i) the
Final  Expiration  Date,  (ii) the time at which  the  Rights  are  redeemed  as
provided in Section 23 hereof or  exchanged  as provided in Section 29 hereof or
(iii) the time at which the Rights expire  pursuant to Section 13(d) hereof (the
earliest of (i),  (ii) and (iii)  being  herein  referred to as the  "Expiration
Date").

                  (b)  The  Purchase  Price  for  each  one  one-hundredth  of a
Preferred  Share pursuant to the exercise of a Right shall initially be $100 and
shall be subject to adjustment  from time to time as provided in Sections 11 and
13(a) hereof and shall be payable in accordance with paragraph (c) below.

                  (c)  Upon  receipt  of  a  Rights   Certificate   representing
exercisable Rights, with the form of election to purchase and the certificate on
the  reverse  side of the  Rights  Certificate  duly  executed,  accompanied  by
payment, with respect to each Right so exercised, of the Purchase Price, as such
amount  may  be  reduced  pursuant  to  Section   11(a)(iii)   hereof,  per  one
one-hundredth of a Preferred Share (or Common Shares, other securities,  cash or
other  assets,  as the case,  may be) to be  purchased as set forth below and an
amount equal to any applicable  transfer tax or other  governmental  charge, the
Rights  Agent  shall,  subject  to  Sections  7(f) and 20(k)  hereof,  thereupon
promptly (i) (A) requisition  from any transfer agent of the shares of Preferred
Stock (or make  available,  if the Rights Agent is the  transfer  agent for such
shares)  certificates for the total number of one  one-hundredths of a Preferred
Share to be purchased and the Company hereby irrevocably authorizes its transfer
agent to comply with all such requests, or (B) if the Company shall have elected
to deposit the total number of Preferred  Shares  issuable  upon exercise of the
Rights hereunder with a depositary agent,  requisition from the depositary agent
depositary  receipts  representing  such  number  of  one  one-hundredths  of  a
Preferred  Share as are to be  purchased  (in which  case  certificates  for the
Preferred Shares represented by such receipts shall be deposited by the transfer
agent with the  depositary  agent) and the Company  will  direct the  depositary
agent to comply with such request,  (ii) requisition from the Company the amount
of cash,  if any, to be paid in lieu of  fractional  shares in  accordance  with
Section 14  hereof,  (iii)  after  receipt of such  certificates  or  depositary
receipts,  cause the same to be delivered to or upon the order of the registered
holder of such Rights  Certificate,  registered  in such name or names as may be
designated by

                                      - 9 -

<PAGE>



such holder,  and (iv) after receipt  thereof,  deliver such cash, if any, to or
upon the order of the registered holder of such Rights Certificate.  The payment
of the  Purchase  Price (as such  amount  may be  reduced  pursuant  to  Section
11(a)(iii) hereof) shall be made in cash or by certified check,  cashier's check
or bank draft payable to the order of the Company. In the event that the Company
is obligated to issue other securities (including Common Shares) of the Company,
pay cash and/or distribute other property pursuant to Section 11(a) hereof,  the
Company will make all arrangements necessary so that such other securities, cash
and/or other property are available for distribution by the Rights Agent, if and
when  appropriate.  The  Company  reserves  the  right to  require  prior to the
occurrence of a Triggering  Event that, upon any exercise of Rights, a number of
Rights be exercised so that only whole Preferred Shares would be issued.

                  (d) In case the  registered  holder of any Rights  Certificate
shall  exercise  less  than  all the  Rights  evidenced  thereby,  a new  Rights
Certificate  evidencing  Rights  equivalent to the Rights remaining  unexercised
shall be issued by the Rights Agent and  delivered to, or upon the order of, the
registered holder of such Rights  Certificate,  registered in such name or names
as may be  designated  by such holder,  subject to the  provisions of Section 14
hereof.

                  (e)   Notwithstanding   anything  in  this  Agreement  to  the
contrary,  from and after the first occurrence of a Section 11(a)(ii) Event, any
Rights  beneficially  owned  by (i)  an  Acquiring  Person  or an  Associate  or
Affiliate of an Acquiring Person which a majority of the Continuing  Trustees in
its sole  discretion  determines is or was involved in or caused or facilitated,
directly or indirectly,  such Section  11(a)(ii) Event, (ii) a transferee of any
such  Acquiring  Person (or of any such  Associate or  Affiliate)  who becomes a
transferee after such Acquiring Person becomes such or (iii) a transferee of any
such  Acquiring  Person (or of any such  Associate or  Affiliate)  who becomes a
transferee prior to or concurrently with such Acquiring Person becoming such and
receives  such  Rights  pursuant  to either (A) a transfer  (whether  or not for
consideration) from such Acquiring Person to holders of equity interests in such
Acquiring  Person  or to any  Person  with whom such  Acquiring  Person  has any
continuing  agreement,  arrangement or  understanding  regarding the transferred
Rights  or (B) a  transfer  which a  majority  of the  Continuing  Trustees  has
determined  is part of a  plan,  arrangement  or  understanding  which  has as a
primary purpose or effect the avoidance of this Section 7(e),  shall become null
and void without any further  action and no holder of such Rights shall have any
rights  whatsoever  with respect to such Rights,  whether under any provision of
this  Agreement or otherwise.  The Company shall use all  reasonable  efforts to
ensure that the  provisions  of this  Section  7(e) and Section  4(b) hereof are
complied  with,  but the Company and the Rights Agent shall have no liability to
any holder of Rights  Certificates  or other Person as a result of the Company's
failure to make any determinations with respect to an Acquiring Person or any of
their Affiliates, Associates or transferees hereunder.

                  (f)   Notwithstanding   anything  in  this  Agreement  to  the
contrary,  neither  the  Rights  Agent nor the  Company  shall be  obligated  to
undertake  any  action  with  respect  to a  registered  holder  of  any  Rights
Certificate  upon the occurrence of any purported  exercise as set forth in this
Section 7 unless such registered  holder shall have (i) completed and signed the
certificate  contained  in the form of  assignment  or election to purchase  set
forth  on the  reverse  side of the  Rights  Certificate  surrendered  for  such
assignment  or  exercise  and (ii)  provided  such  additional  evidence  of the
identity of the Beneficial Owner (or former  Beneficial  Owner) or Affiliates or
Associates thereof as the Company shall reasonably request.

         Section 8.  Cancellation  and Destruction of Rights  Certificates.  All
Rights Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered

                                     - 10 -

<PAGE>



to the  Company or any of its  agents,  be  delivered  to the  Rights  Agent for
cancellation  or in cancelled form or if surrendered to the Rights Agent,  shall
be cancelled by it, and no Rights  Certificates  shall be issued in lieu thereof
except as expressly  permitted by any of the provisions of this  Agreement.  The
Company shall deliver to the Rights Agent for cancellation  and retirement,  and
the  Rights  Agent  shall so cancel and  retire,  any other  Rights  Certificate
purchased or acquired by the Company  otherwise than upon the exercise  thereof.
The Rights Agent shall deliver all cancelled Rights Certificates to the Company,
or shall, at the written request of the Company,  destroy such cancelled  Rights
Certificates,  and in such case  shall  deliver  a  certificate  of  destruction
thereof to the Company.

         Section 9. Reservation and Availability of Capital Stock.

                  (a) The Company  covenants and agrees that it will cause to be
reserved and kept available out of its authorized and unissued  Preferred Shares
(and,  following the occurrence of a Triggering Event, out of its authorized and
unissued  Common Shares and/or other  securities  or out of its  authorized  and
issued  shares  held in its  treasury),  the number of  Preferred  Shares  (and,
following  the  occurrence  of a Triggering  Event,  Common  Shares and/or other
securities) that, as provided in this Agreement  (including  Section  11(a)(iii)
hereof),  will be sufficient  to permit the exercise in full of all  outstanding
Rights.

                  (b) So  long  as the  Preferred  Shares  (and,  following  the
occurrence  of a  Triggering  Event,  Common  Shares  and/or  other  securities)
issuable  and  deliverable  upon the exercise of the Rights may be listed on any
national  securities  exchange,  the Company shall use its reasonable efforts to
cause,  from and after such time as the Rights  become  exercisable,  all shares
reserved for such issuance to be listed on such exchange upon official notice of
issuance upon such exercise.

                  (c) The Company shall use all reasonable  efforts to (i) file,
as soon as practicable following the earliest date after the first occurrence of
a  Triggering  Event in which the  consideration  to be delivered by the Company
upon  exercise  of the  Rights  has been  determined  in  accordance  with  this
Agreement,  a registration  statement under the Act on an appropriate  form with
respect to the securities  purchasable  upon exercise of the Rights,  (ii) cause
such  registration  statement to become  effective as soon as practicable  after
such  filing and (iii) cause such  registration  statement  to remain  effective
(with a prospectus at all times meeting the  requirements  of the Act) until the
earlier  of (A) the date as of which the Rights  are no longer  exercisable  for
such  securities  or (B) the  Expiration  Date.  The Company will also take such
action as may be appropriate under, or to ensure compliance with, the securities
or "blue sky" laws of the various states in connection  with the  exercisability
of the  Rights.  The  Company  may,  acting by  resolution  of its Board  (which
resolution  shall be effective  only with the  concurrence  of a majority of the
Continuing  Trustees),  temporarily  suspend, for a period of time not to exceed
ninety (90) days after the date set forth in clause (i) of the first sentence of
this Section 9(c), the exercisability of the Rights in order to prepare and file
such registration  statement and permit it to become effective.  In the event of
any such suspension,  the Company shall issue a public announcement stating that
the  exercisability of the Rights has been temporarily  suspended,  as well as a
public  announcement  at such time as the suspension is no longer in effect.  In
addition,  if the Company  shall  determine  that a  registration  statement  is
required in other circumstances following the Distribution Date, the Company may
similarly  temporarily  suspend the exercisability of the Rights until such time
as a registration  statement has been declared  effective.  Notwithstanding  any
provision of this Agreement to the contrary, the Rights shall not be exercisable
in any jurisdiction if the requisite  qualification in such  jurisdiction  shall
not have been  obtained,  the exercise  thereof shall not otherwise be permitted
under  applicable law or a registration  statement  shall not have been declared
effective.

                  (d) The  Company  covenants  and agrees  that it will take all
such  action as may be  necessary  to ensure  that all one  one-hundredths  of a
Preferred  Share (and,  following the occurrence of a Triggering  Event,  Common
Shares and/or other securities)  delivered upon exercise of Rights shall, at the
time of delivery of the  certificates for such shares (subject to payment of the
Purchase  Price),  be duly and validly  authorized  and  issued,  fully paid and
nonassessable.

                  (e) The Company further  covenants and agrees that,  except as
set forth in Section 6(a)  hereof,  it will pay when due and payable any and all
federal and state transfer taxes and similar  governmental  charges which may be
payable in respect of the issuance or delivery of the Rights Certificates and of
any  certificates  for a number of one  one-hundredths  of a Preferred Share (or
Common Shares and/or other securities,  as the case may be) upon the exercise of
Rights.  The Company shall not, however,  be required to pay any transfer tax or
other  governmental  charge  which may be payable in respect of any  transfer or
delivery  of Rights  Certificates  to a Person  other than,  or the  issuance or
delivery  of a number of one  one-hundredths  of a  Preferred  Share (or  Common
Shares and/or other  securities,  as the case may be) in respect of a name other
than that of, the registered holder of the Rights Certificates evidencing Rights
surrendered for exercise,  nor shall the Company be required to issue or deliver
any  certificates  for a number of one  one-hundredths  of a Preferred Share (or
Common Shares and/or other securities,  as the case may be) in a name other than
that of the registered  holder upon the exercise of any Rights until such tax or
charge shall have been paid (any such tax or charge being  payable by the holder
of such  Rights  Certificate  at the  time of  surrender)  or  until it has been
established to the Company's satisfaction that no such tax or charge is due.

         Section 10.  Preferred Share Record Date. Each person in whose name any
certificate for a number of one  one-hundredths  of a Preferred Share (or Common
Shares and/or other securities,  as the case may be) is issued upon the exercise
of Rights  shall for all  purposes be deemed to have become the holder of record
of such fractional Preferred Share (or Common Shares and/or other securities, as
the case may be) represented  thereby on, and such  certificate  shall be dated,
the date upon  which the  Rights  Certificate  evidencing  such  Rights was duly
surrendered and payment of the Purchase Price (and all applicable transfer taxes
and other governmental charges) was made; provided, however, that if the date of
such surrender and payment is a date upon which the Preferred  Shares (or Common
Shares  and/or  other  securities,  as the  case may be)  transfer  books of the
Company are closed, such Person shall be deemed to have become the record holder
of such shares  (fractional  or  otherwise)  on, and such  certificate  shall be
dated, the next succeeding Business Day on which the Preferred Shares (or Common
Shares  and/or  other  securities,  as the  case may be)  transfer  books of the
Company are open.  Prior to the exercise of the Rights  evidenced  thereby,  the
holder  of a  Rights  Certificate  shall  not be  entitled  to any  rights  of a
shareholder  of the Company with respect to shares for which the Rights shall be
exercisable,  including  without  limitation  the  right  to  vote,  to  receive
dividends or other distributions or to exercise any preemptive rights, and shall
not be entitled to receive any notice of any proceedings of the Company,  except
as provided herein.

         Section 11. Adjustment of Purchase Price,  Number and Kind of Shares or
Number of  Rights.  The  Purchase  Price,  the  number  and kind of  shares,  or
fractions thereof, purchasable upon the exercise of each Right and the number of
Rights  outstanding  are subject to adjustment  from time to time as provided in
this Section 11.

                  (a) (i) In the event the  Company  shall at any time after the
date of this Agreement (A) declare a dividend on the Preferred Shares payable in
Preferred Shares,  (B) subdivide or split the outstanding  Preferred Shares, (C)
combine or consolidate the outstanding Preferred Shares into a smaller number of
shares or (D) issue any shares of its capital stock in a reclassification of the
Preferred

                                     - 12 -

<PAGE>



Shares (including any such  reclassification  in connection with a consolidation
or merger in which the  Company is the  continuing  or  surviving  corporation),
except as otherwise  provided in this Section 11(a) and Section 7(e) hereof, the
Purchase  Price in effect at the time of the record date for such dividend or of
the effective date of such  subdivision,  split,  combination,  consolidation or
reclassification,  and the number and kind of Preferred Shares or capital stock,
as the case may be, issuable on such date, shall be proportionately  adjusted so
that the holder of any Right  exercised  after such time  shall be  entitled  to
receive, upon payment of the Purchase Price then in effect, the aggregate number
and kind of Preferred  Shares or capital  stock,  as the case may be, which,  if
such Right had been exercised  immediately prior to such date and at a time when
the Preferred Shares (or other capital stock, as the case may be) transfer books
of the  Company  were open,  he would have  owned  upon such  exercise  and been
entitled to receive by virtue of such dividend, subdivision, split, combination,
consolidation  or  reclassification.  If an event occurs which would  require an
adjustment under both this Section 11(a)(i) and Section  11(a)(ii)  hereof,  the
adjustment  provided for in this Section  11(a)(i)  shall be in addition to, and
shall be made prior to, any adjustment  required  pursuant to Section  11(a)(ii)
hereof.

                   (ii) In the event (a  "Section  11(a)(ii)  Event") any Person
(other  than an  Exempt  Person)  alone  or  together  with its  Affiliates  and
Associates  (other than an Exempt  Person)  shall,  at any time after the Rights
Dividend Declaration Date, become an Acquiring Person,  unless the event causing
such  Person to become an  Acquiring  Person is (x) a Section 13 Event or (y) an
acquisition  of Common  Shares of the Company  pursuant to a tender  offer or an
exchange offer for all  outstanding  Common Shares of the Company at a price and
on terms  determined  by at least a  majority  of the  Outside  Trustees,  after
receiving advice from one or more investment banking firms, to be (a) at a price
which is fair to  shareholders  (taking  into  account  all  factors  which such
Outside Trustees deem relevant including, without limitation, prices which could
reasonably  be  achieved  if the  Company or its assets  were sold on an orderly
basis designed to realize maximum value) and (b) otherwise in the best interests
of the Company and its shareholders,  then promptly after the date of occurrence
of a Section 11(a)(ii) Event, proper provision shall be made so that each holder
of a  Right  (except  as  provided  below  and in  Section  7(e)  hereof)  shall
thereafter have the right to receive,  upon exercise thereof at the then current
Purchase  Price in  accordance  with the terms of this  Agreement,  in lieu of a
number of one  one-hundredths of a Preferred Share, such number of Common Shares
of the Company as shall equal the result  obtained by (x)  multiplying  the then
current Purchase Price by the then number of one  one-hundredths  of a Preferred
Share  for  which  a  Right  was  exercisable  immediately  prior  to the  first
occurrence  of a Section  11(a)(ii)  Event,  whether  or not such Right was then
exercisable,  and  (y)  dividing  that  product  (which,  following  such  first
occurrence,  shall  thereafter be referred to as the  "Purchase  Price" for each
Right and for all purposes of this Agreement) by 50% of the Current Market Price
per share of Common  Shares of the Company on the date of such first  occurrence
(such number of shares being referred to as the "Adjustment Shares").

                   (iii) In lieu of  issuing  Common  Shares of the  Company  in
accordance with Section 11(a)(ii) hereof,  the Company,  acting by resolution of
the Board (which  resolution  shall be effective only with the  concurrence of a
majority of the Continuing  Trustees),  may, and in the event that the number of
Common Shares of the Company which are  authorized by the Company's  Declaration
of Trust (as the same may be  amended  and  restated  from time to time) but not
outstanding  or reserved for issuance for purposes  other than upon  exercise of
the Rights is not  sufficient  to permit the  exercise  in full of the Rights in
accordance  with the  foregoing  subparagraph  (ii) of this Section  11(a),  the
Company,  acting by resolution of the Board (which resolution shall be effective
only with the concurrence of a majority of the Continuing  Trustees),  shall (A)
determine the excess of (1) the value of the Adjustment Shares issuable upon the
exercise  of  a  Right  (the  "Current  Value")  over  (2)  the  Purchase  Price
attributable to each Right (such excess being referred to as the "Spread"),  and


                                     - 13 -

<PAGE>


(B) with respect to each Right  (subject to Section 7(e) hereof),  make adequate
provision  to  substitute  for  the  Adjustment  Shares,  upon  payment  of  the
applicable  Purchase Price, (1) cash, (2) a reduction in the Purchase Price, (3)
equity  securities  of the  Company  other  than  Common  Shares of the  Company
(including, without limitation,  preferred shares, or units of preferred shares,
of  preferred  stock which the Board has deemed to have the same value as Common
Shares  (such  shares of  preferred  stock being  referred to as "Common  Shares
Equivalents")),  (4) debt securities of the Company, (5) other assets or (6) any
combination of the foregoing which,  when added to any Common Shares issued upon
such exercise,  have an aggregate  value equal to the Current Value,  where such
aggregate  value has been  determined  by the Board (with the  concurrence  of a
majority  of the  Continuing  Trustees)  based upon the  advice of a  nationally
recognized investment banking firm selected by the Board; provided,  however, if
the Company shall not have made adequate  provision to deliver value pursuant to
clause  (B) above  within  thirty 30 days  following  the later of (x) the first
occurrence of a Section  11(a)(ii) Event and (y) the date on which the Company's
right of  redemption  pursuant  to  Section  23(a)  hereof,  as such date may be
amended  pursuant to Section 26 hereof,  expires (the later of (x) and (y) being
referred to herein as the "Section  11(a)(ii)  Trigger Date"),  then the Company
shall be obligated to deliver,  upon the  surrender  for exercise of a Right and
without  requiring  payment of the Purchase Price,  Common Shares of the Company
(to the extent available) and then, if necessary, cash, which shares and/or cash
have an aggregate value equal to the Spread.  If the Board (with the concurrence
of a majority of the Continuing  Trustees) shall determine in good faith that it
is likely that  sufficient  additional  Common  Shares of the  Company  could be
authorized for issuance upon exercise in full of the Rights, the thirty (30) day
period set forth  above may be extended  to the extent  necessary,  but not more
than ninety (90) days after the Section  11(a)(ii)  Trigger  Date, in order that
the Company may seek shareholder approval, if required, for the authorization of
such  additional  shares (such period,  as it may be extended  being referred to
herein as the "Substitution  Period"). To the extent that the Company determines
that some action need be taken pursuant to the first and/or second  sentences of
this Section 11(a)(iii),  the Company (x) shall provide, subject to Section 7(e)
hereof, that such action shall apply uniformly to all outstanding Rights and (y)
may  suspend  the  exercisability  of the  Rights  until the  expiration  of the
Substitution  Period in order to seek any  authorization  of  additional  shares
and/or to decide the  appropriate  form of  distribution  to be made pursuant to
such first sentence and to determine the value thereof. In the event of any such
suspension,  the Company  shall  issue a public  announcement  stating  that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement at such time as the suspension is no longer in effect. For purposes
of this Section 11(a)(iii),  the value of each Common Share of the Company shall
be the Current Market Price per share of the Common Shares of the Company on the
Section  11(a)(ii)  Trigger Date and the value of any Common  Shares  Equivalent
shall be deemed to have the same  value as the Common  Shares of the  Company on
such date.

                  (b) In case  the  Company  shall  fix a  record  date  for the
issuance  of rights,  options or warrants  to all  holders of  Preferred  Shares
entitling  them to subscribe  for or purchase (for a period  expiring  within 45
calendar  days after such record date)  Preferred  Shares (or shares  having the
same rights,  privileges and  preferences as the Preferred  Shares  ("Equivalent
Preferred   Shares"))  or  securities   convertible  into  Preferred  Shares  or
Equivalent  Preferred  Shares at a price per Preferred  Share or per  Equivalent
Preferred  Share  (or  having  a  conversion  price  per  share,  if a  security
convertible into Preferred Shares or Equivalent  Preferred Shares) less than the
Current Market Price per Preferred Share on such record date, the Purchase Price
to be in effect after such record date shall be  determined by  multiplying  the
Purchase  Price in effect  immediately  prior to such record date by a fraction,
the numerator of which shall be the number of Preferred  Shares  outstanding  on
such  record  date,  plus the  number  of  Preferred  Shares  and/or  Equivalent
Preferred Shares which the aggregate subscription or Purchase Price of the total
number of Preferred Shares and/or Equivalent Preferred Shares so to be

                                     - 14 -

offered  (and/or  the  aggregate  initial  conversion  price of the  convertible
securities so to be offered) would  purchase at such Current  Market Price,  and
the denominator of which shall be the number of Preferred Shares  outstanding on
such  record  date,  plus  the  number  of  additional  Preferred  Stock  and/or
Equivalent  Preferred Stock to be offered for  subscription or purchase (or into
which the convertible securities so to be offered are initially convertible). In
case such  subscription  price may be paid by delivery of consideration  part or
all of which may be in a form other than cash,  the value of such  consideration
shall be as  determined  in good faith by the Board (with the  concurrence  of a
majority of the Continuing Trustees),  whose determination shall be described in
a  statement  filed  with the  Rights  Agent  and  shall be  conclusive  for all
purposes.  Shares of  Preferred  Stock  owned by or held for the  account of the
Company shall not be deemed outstanding for the purpose of any such computation.
Such adjustment shall be made successively whenever such a record date is fixed,
and in the event that such rights,  options or warrants  are not so issued,  the
Purchase Price shall be adjusted to be the Purchase Price which would then be in
effect if such record date had not been fixed.

                  (c)  In  case  the  Company  shall  fix a  record  date  for a
distribution to all holders of Preferred Shares (including any such distribution
made in connection  with a  consolidation  or merger in which the Company is the
continuing or surviving  corporation) of evidences of indebtedness,  cash (other
than a regular  periodic cash dividend out of the earnings or retained  earnings
of the Company),  assets (other than a dividend payable in Preferred Shares, but
including  any  dividend  payable  in stock  other  than  Preferred  Shares)  or
subscription  rights or warrants  (excluding  those referred to in Section 11(b)
hereof),  the  Purchase  Price to be in effect  after such  record date shall be
determined by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction,  the  numerator of which shall be the Current  Market
Price per share of  Preferred  Stock on such record  date,  less the fair market
value (as  determined  in good  faith by the Board  (with the  concurrence  of a
majority of the Continuing Trustees),  whose determination shall be described in
a  statement  filed with the Rights  Agent and shall be binding  upon the Rights
Agent and the  holders  of the  Rights) of the  portion  of the cash,  assets or
evidences of indebtedness so to be distributed or of such subscription rights or
warrants  applicable to a Preferred Shares and the denominator of which shall be
such Current Market Price per Preferred Share.  Such  adjustments  shall be made
successively  whenever  such a record date is fixed,  and in the event that such
distribution  is not so made,  the  Purchase  Price  shall be adjusted to be the
Purchase  Price which would have been in effect if such record date had not been
fixed.

                  (d) (i) For the purpose of any  computation  hereunder,  other
than computations made pursuant to Section 11(a)(iii) hereof, the Current Market
Price per  Common  Share on any date  shall be deemed to be the  average  of the
daily  closing  prices  per  share of such  Common  Share  for the  thirty  (30)
consecutive  Trading Days  immediately  prior to such date,  and for purposes of
computations  made pursuant to Section  11(a)(iii)  hereof,  the Current  Market
Price per share of Common Share on any date shall be deemed to be the average of
the daily  closing  prices  per such  Common  Share or the ten (10)  consecutive
Trading Days immediately  following such date;  provided,  however,  that in the
event that the Current  Market Price per share of the Common Share is determined
during a period  following the  announcement by the Company of (A) a dividend or
distribution  on such  Common  Share  payable  in Common  Shares  or  securities
convertible into shares of such Common Shares (other than the Rights) or (B) any
subdivision, combination, consolidation, reverse stock split or reclassification
of Common  Shares,  and prior to the  expiration  of the  requisite  thirty (30)
Trading  Days or ten (10)  Trading Day  period,  as set forth  above,  after the
ex-dividend date for such dividend or distribution,  or the record date for such
subdivision,    combination,    consolidation,    reverse    stock    split   or
reclassification,  then,  in each such case,  the Current  Market Price shall be
properly adjusted to take into account  ex-dividend  trading.  The closing price
for each day shall be the last sale price,  regular way, or in case no such sale
takes  place on such day,  the  average  of the  closing  bid and asked  prices,
regular way, in either case as

                                     - 15 -

reported in the principal consolidated transaction reporting system with respect
to securities  listed or admitted to trading on the New York Stock Exchange,  or
if the Common Shares are not listed or admitted to trading on the New York Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national  securities exchange
on which the Common  Shares are listed or admitted to trading,  or if the Common
Shares  are not  listed  or  admitted  to  trading  on any  national  securities
exchange,  the last quoted price,  or if not so quoted,  the average of the high
bid and low asked  prices in the  over-the-counter  market,  as  reported by the
Nasdaq National Market or the Nasdaq Stock Market or such other quotation system
then in use, or if on any such date the Common Shares are not quoted by any such
organization,  the average of the closing bid and asked prices as furnished by a
professional  market maker making a market in the Common Shares  selected by the
Board (with the  concurrence of a majority of the Continuing  Trustees).  If the
Common  Shares are not publicly held or not so listed,  traded or quoted,  and a
market  maker is not making a market,  Current  Market Price per share of Common
Shares  shall mean the fair value per share as  determined  in good faith by the
Board (with the  concurrence  of a majority of the Continuing  Trustees),  whose
determination  shall be described in a statement filed with the Rights Agent and
shall be conclusive for all purposes.

                   (ii)  For  the  purpose  of any  computation  hereunder,  the
Current Market Price per Preferred  Share shall be determined in the same manner
as set forth  above for the Common  Shares in clause (i) of this  Section  11(d)
(other  than the  last  sentence  thereof).  If the  Current  Market  Price  per
Preferred  Share cannot be  determined  in the manner  provided  above or if the
Preferred  Stock is not publicly held or listed or traded in a manner  described
in clause (i) of this  Section  11(d),  the  Current  Market  Price per share of
Preferred  Stock shall be  conclusively  deemed to be an amount equal to 100 (as
such number may be appropriately adjusted for such events as stock splits, stock
dividends  and  recapitalizations  with respect to the Common  Shares  occurring
after the date of this  Agreement)  multiplied  by the Current  Market Price per
share of the Common Shares. If neither the Common Shares nor the Preferred Stock
are publicly held or so listed or traded,  Current Market Price per share of the
Preferred  Stock shall mean the fair value per share as determined in good faith
by the Board (with the  concurrence of a majority of the  Continuing  Trustees),
whose  determination  shall be  described  in a statement  filed with the Rights
Agent  and  shall be  conclusive  for all  purposes.  For all  purposes  of this
Agreement,  the Current Market Price of one  one-hundredth  of a Preferred Share
shall be equal to the Current  Market Price of one  Preferred  Share  divided by
100. The term  "Trading  Day" shall mean a day on which the  principal  national
securities exchange on which the Common Shares are listed or admitted to trading
is open for the transaction of business,  or if the Common Shares are not listed
or admitted to trading on any national securities exchange, a Business Day.

                  (e)  Anything  herein  to  the  contrary  notwithstanding,  no
adjustment in the Purchase Price shall be required unless such adjustment  would
require an increase or  decrease  of at least one percent  (1%) in the  Purchase
Price;  provided,  however, that any adjustments which by reason of this Section
11(e) are not  required  to be made  shall be  carried  forward  and taken  into
account in any subsequent  adjustment.  All  calculations  under this Section 11
shall be made to the nearest cent or to the nearest thousandth of a Common Share
or other  share  or  one-millionth  of a  Preferred  Share,  as the case may be.
Notwithstanding  the  first  sentence  of this  Section  11(e),  any  adjustment
required by this Section 11 shall be made no later than the earlier of (i) three
(3) years from the date of the  transaction  which  mandates such  adjustment or
(ii) the Expiration Date.

                  (f) If as a result of an  adjustment  made pursuant to Section
11(a)(ii) or Section 13(a) hereof, the holder of any Right thereafter  exercised
shall  become  entitled  to  receive  any  shares of  capital  stock  other than
Preferred Shares, thereafter the number of such other shares so receivable upon

                                     - 16 -

exercise of any Right and the Purchase  Price  thereof (or the number of rights)
shall be  subject  to  adjustment  from time to time in a manner and on terms as
nearly equivalent as practicable to the provisions with respect to the Preferred
Shares  contained in Sections ll(a),  (b), (c), (e), (g), (h), (i), (j), (k) and
(m), and the  provisions  of Sections 7, 9, 10, 13 and 14 hereof with respect to
the  Preferred  Shares  shall  apply on like  terms to any  such  other  shares;
provided,  however,  that the Company  shall not be liable for its  inability to
reserve and keep available for issuance upon exercise of the Rights  pursuant to
Section  11(a)(ii)  a number of Common  Shares of the Company  greater  than the
number then authorized by the Company's Declaration of Trust (as the same may be
amended and restated from time to time) but not  outstanding or reserved for any
other purpose.

                  (g) All Rights originally issued by the Company  subsequent to
any adjustment  made to the Purchase Price hereunder shall evidence the right to
purchase,  at the adjusted Purchase Price, the number of one one-hundredths of a
Preferred  Share  purchasable  from time to time  hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

                  (h) Unless the Company  shall have  exercised  its election as
provided in Section  11(i),  upon each  adjustment  of the  Purchase  Price as a
result  of  the  calculations  made  in  Sections  ll(b)  and  (e),  each  Right
outstanding  immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase,  at the adjusted  Purchase Price, that number of
one  one-hundredths  of  a  Preferred  Share  (calculated  to  the  nearest  one
one-millionth  of a share)  obtained  by (i)  multiplying  (x) the number of one
one-hundredths  of a  share  covered  by  a  Right  immediately  prior  to  this
adjustment,  by (y) the  Purchase  Price  in  effect  immediately  prior to such
adjustment of the Purchase  Price,  and (ii) dividing the product so obtained by
the Purchase Price in effect  immediately  after such adjustment of the Purchase
Price.

                  (i)  The  Company  may  elect  on or  after  the  date  of any
adjustment of the Purchase Price to adjust the number of Rights,  in lieu of any
adjustment in the number of one  one-hundredths of a Preferred Share purchasable
upon  the  exercise  of a  Right.  Each  of the  Rights  outstanding  after  the
adjustment  in the number of Rights shall be  exercisable  for the number of one
one-hundredths   of  a  Preferred  Share  for  which  a  Right  was  exercisable
immediately  prior to such  adjustment.  Each Right held of record prior to such
adjustment  of  the  number  of  Rights  shall  become  that  number  of  Rights
(calculated to the nearest one-ten thousandth) obtained by dividing the Purchase
Price in effect  immediately  prior to adjustment  of the Purchase  Price by the
Purchase Price in effect immediately after adjustment of the Purchase Price. The
Company shall make a public announcement of its election to adjust the number of
Rights,  indicating  the record  date for the  adjustment,  and, if known at the
time, the amount of the adjustment to be made.  This record date may be the date
on which the  Purchase  Price is  adjusted  or any day  thereafter,  but, if the
Rights Certificates have been issued, shall be at least ten (10) days later than
the date of the public  announcement.  If Rights  Certificates have been issued,
upon each adjustment of the number of Rights pursuant to this Section 11(i), the
Company shall, as promptly as practicable, cause to be distributed to holders of
record  of  Rights   Certificates  on  such  record  date  Rights   Certificates
evidencing,  subject to Section 14 hereof,  the additional  Rights to which such
holders  shall be entitled as a result of such  adjustment,  or at the option of
the  Company,  shall  cause to be  distributed  to such  holders  of  record  in
substitution  and replacement for the Rights  Certificates  held by such holders
prior to the date of adjustment,  and upon surrender thereof, if required by the
Company, new Rights Certificates evidencing all the Rights to which such holders
shall  be  entitled  after  such  adjustment.   Rights  Certificates  so  to  be
distributed  shall be issued,  executed and countersigned in the manner provided
for herein (and may bear,  at the option of the Company,  the adjusted  Purchase
Price) and shall be  registered  in the names of the holders of record of Rights
Certificates on the record date specified in the public announcement.

                  (j)  Irrespective  of any adjustment or change in the Purchase
Price or the number of one one-hundredths of a Preferred Share issuable upon the
exercise of the  Rights,  the Rights  Certificates  theretofore  and  thereafter
issued may continue to express the Purchase  Price per one  one-hundredths  of a
share and the number of one  one-hundredths  of a share which were  expressed in
the initial Rights Certificates issued hereunder.

                  (k) Before  taking any action that would  cause an  adjustment
reducing the Purchase  Price below the then stated value,  if any, of the number
of one one-hundredths of a Preferred Share issuable upon exercise of the Rights,
the Company shall use its best efforts to take any  corporate  action which may,
in the  opinion of its  counsel,  be  necessary  in order that the  Company  may
validly  and  legally  issue  fully paid and  nonassessable  such  number of one
one-hundredths of a Preferred Share at such adjusted Purchase Price.

                  (l) In any case in which this Section 11 shall require that an
adjustment  in the  Purchase  Price be made  effective as of a record date for a
specified  event,  the Company may elect to defer until the  occurrence  of such
event the issuance to the holder of any Right  exercised  after such record date
the number of one one-hundredths of a Preferred Share and other capital stock or
securities  of the Company,  if any,  issuable upon such exercise over and above
the number of one one-hundredths of a share of Preferred Stock and other capital
stock or securities of the Company,  if any,  issuable upon such exercise on the
basis of the  Purchase  Price in  effect  prior  to such  adjustment;  provided,
however,  that the  Company  shall  deliver  to such  holder a due bill or other
appropriate instrument evidencing such holder's right to receive such additional
shares  (fractional or otherwise) or securities upon the occurrence of the event
requiring such adjustment.

                  (m)   Anything   in   this   Section   11  to   the   contrary
notwithstanding,  the Company shall be entitled to make such  adjustments in the
Purchase  Price,  in addition to those  adjustments  expressly  required by this
Section 11, as and to the extent that in its good faith judgment the Board shall
determine to be advisable in order that any (i)  consolidation or subdivision of
the Preferred  Shares,  (ii) issuance wholly for cash of any Preferred Shares at
less than the Current Market Price,  (iii) issuance wholly for cash of Preferred
Shares or securities  which by their terms are convertible  into or exchangeable
for Preferred Shares, (iv) stock dividends or (v) issuance of rights, options or
warrants  referred  to in this  Section  11,  hereafter  made by the  Company to
holders of its Preferred Shares shall not be taxable to such shareholders.

                  (n) The Company covenants and agrees that it shall not, at any
time after the  Distribution  Date, (i) consolidate with any other Person (other
than a Subsidiary  of the Company in a transaction  which  complies with Section
11(o) hereof), (ii) merge with or into any other Person (other than a Subsidiary
of the Company in a  transaction  which  complies  with Section 11(o) hereof) or
(iii) sell or transfer (or permit any  Subsidiary to sell or  transfer),  in one
transaction,  or a series  of  related  transactions,  assets or  earning  power
aggregating  more than 50% of the assets or earning power of the Company and its
Subsidiaries  (taken as a whole) to any other Person or Persons  (other than the
Company and/or any of its Subsidiaries in one or more transactions each of which
complies with Section 11(o) hereof),  if (x) at the time of or immediately after
such consolidation,  merger, sale or transfer there are any rights,  warrants or
other instruments or securities  outstanding or agreements in effect which would
substantially  diminish  or  otherwise  eliminate  the  benefits  intended to be
afforded by the Rights or (y) prior to, simultaneously with or immediately after
such consolidation, merger, sale or transfer, the stockholders of the Person who
constitutes, or would constitute, the "Principal Party"

                                     - 18 -

for  purposes of Section  13(a)  hereof shall have  received a  distribution  of
Rights previously owned by such Person or any of its Affiliates and Associates.

                  (o)  The  Company   covenants  and  agrees  that,   after  the
Distribution  Date, it will not,  except as permitted by Section 23, Section 26,
Section 29 or Section 31  hereof,  take (or permit any  Subsidiary  to take) any
action if at the time such  action is taken it is  reasonably  foreseeable  that
such action will  diminish  substantially  or otherwise  eliminate  the benefits
intended to be afforded by the Rights.

                  (p)    Anything   in   this    Agreement   to   the   contrary
notwithstanding,  in the  event  that the  Company  shall at any time  after the
Rights Dividend  Declaration Date and prior to the Distribution Date (i) declare
a dividend on the  outstanding  Common  Shares of the Company  payable in Common
Shares of the Company,  (ii)  subdivide  the  outstanding  Common  Shares of the
Company in a manner not covered in (i) above or (iii)  combine  the  outstanding
Common Shares of the Company into a smaller number of shares,  (x) the number of
one  one-hundredths  of a Preferred  Share then  purchasable  upon exercise of a
Right shall be proportionately adjusted so that the number of one one-hundredths
of a Preferred Share  purchasable  thereafter upon proper exercise of each Right
shall equal the result obtained by multiplying the number of one  one-hundredths
of a  Preferred  Share  so  purchasable  immediately  prior  to such  event by a
fraction the  numerator  of which shall be the total number of Common  Shares of
the Company outstanding immediately prior to the occurrence of the event and the
denominator  of which shall be the total number of Common  Shares of the Company
outstanding  immediately  following the  occurrence of such event and (y) action
shall be taken such that each share of Common Shares of the Company  outstanding
immediately after such event shall have issued with respect to it that number of
Rights which each share of Common Shares of the Company outstanding  immediately
prior to such event had issued with respect to it. The adjustments  provided for
in this Section  11(p) shall be made  successively  whenever  such a dividend is
declared  or  paid  or  such a  subdivision,  combination  or  consolidation  is
effected.  If an event occurs which would  require an  adjustment  under Section
11(a)(ii) and this Section 11(p),  the adjustments  provided for in this Section
11(p)  shall be in addition  and prior to any  adjustment  required  pursuant to
Section 11(a)(ii).

         Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an  adjustment is made as provided in Section 11 and Section 13 hereof,
the  Company  shall  (a)  promptly  prepare a  certificate  setting  forth  such
adjustment and a brief  statement of the facts  accounting for such  adjustment,
(b) promptly  file with the Rights Agent,  and with each transfer  agent for the
Preferred  Shares  and  the  Common  Shares  of  the  Company,  a copy  of  such
certificate  and (c) mail a brief  summary  thereof  to each  holder of a Rights
Certificate  (or  if  prior  to the  Distribution  Date,  to  each  holder  of a
certificate  representing  Common  Shares of the  Company)  in  accordance  with
Section 25 hereof.  Notwithstanding the foregoing  sentence,  the failure of the
Company  to  prepare  such  certificate  or  statement  or make such  filings or
mailings  shall not  affect  the  validity  of, or the force or effect  of,  the
requirement  for such  adjustment.  The Rights Agent shall be fully protected in
relying on any such certificate and on any adjustment therein contained.

         Section  13.  Consolidation,  Merger or Sale or  Transfer  of Assets or
Earning Power.

                  (a) In the event (a "Section 13 Event")  that, on or after the
Stock  Acquisition  Date,   directly  or  indirectly,   (x)  the  Company  shall
consolidate  or otherwise  combine with, or merge with or into, any other Person
or Persons  (other  than a  Subsidiary  of the  Company in a  transaction  which
complies with Section 11(o) hereof), and the Company shall not be the continuing
or surviving  corporation of such consolidation,  combination or merger, (y) any
Person or Persons (other than a

                                     - 19 -

<PAGE>



Subsidiary  of the Company in a  transaction  which  complies with Section 11(o)
hereof) shall  consolidate  or combine with, or merge with or into, the Company,
and the  Company  shall  be the  continuing  or  surviving  corporation  of such
consolidation, combination or merger and, in connection with such consolidation,
combination  or  merger,  all or part of the  outstanding  Common  Shares of the
Company shall be changed into or exchanged for stock or other  securities of any
other Person or Persons or cash or any other  property or (z) the Company  shall
sell or  otherwise  transfer (or one or more of its  Subsidiaries  shall sell or
otherwise  transfer),  in one  transaction or a series of related  transactions,
assets or earning power aggregating more than 50% of the assets or earning power
of the  Company and its  Subsidiaries  (taken as a whole and  calculated  on the
basis of the Company's most recent regularly prepared  financial  statements) to
any Person or Persons  (other than the Company or any  Subsidiary of the Company
in one or more  transactions  each of which complies with Section 11(o) hereof);
provided,  however, that this clause (z) of Section 13(a) shall not apply to the
pro rata  distribution  by the Company of assets  (including  securities) of the
Company  or any of its  Subsidiaries  to all  holders  of the  Company's  Common
Shares;  then, and in each such case (except as may be  contemplated  by Section
13(d)  hereof),  proper  provision  shall be made so that:  (i) each holder of a
Right,  except as provided in Section 7(e) hereof,  shall, on or after the later
of (A) the date of the first  occurrence of any such Section 13 Event or (B) the
date of the  expiration  of the period  within  which the Rights may be redeemed
pursuant  to Section 23 hereof  (as the same may be  amended  or  reinstated  as
provided  in Section 26 or Section 31 hereof,  respectively),  have the right to
receive,  upon the  exercise  thereof  at the  then  current  Purchase  Price in
accordance with the terms of this Agreement,  such number of validly  authorized
and issued, fully paid,  nonassessable and freely tradeable Common Shares of the
Principal Party, not subject to any liens, encumbrances, rights of first refusal
or other  adverse  claims,  as shall be  equal  to the  result  obtained  by (1)
multiplying the then current Purchase Price by the number of one  one-hundredths
of a Preferred Share for which a Right is exercisable  immediately  prior to the
first  occurrence  of a Section 13 Event (or, if a Section  11(a)(ii)  Event has
occurred prior to the first  occurrence of a Section 13 Event,  multiplying  the
number of such one  one-hundredths  of a share for which a Right was exercisable
immediately  prior to the first  occurrence of a Section  11(a)(ii) Event by the
Purchase Price in effect  immediately prior to such first  occurrence),  and (2)
dividing that product  (which,  following  the first  occurrence of a Section 13
Event,  shall be referred to as the "Purchase  Price" for each Right and for all
purposes of this  Agreement)  by 50% of the Current  Market Price per the Common
Share of such  Principal  Party on the date of  consummation  of such Section 13
Event;  (ii) such  Principal  Party shall  thereafter  be liable for,  and shall
assume,  by virtue of such Section 13 Event,  all the  obligations and duties of
the  Company  pursuant  to  this  Agreement;  (iii)  the  term  "Company"  shall
thereafter be deemed to refer to such  Principal  Party,  it being  specifically
intended  that the  provisions  of  Section 11 hereof  shall  apply only to such
Principal Party following the first occurrence of a Section 13 Event;  (iv) such
Principal  Party  shall  take such steps  (including,  but not  limited  to, the
reservation of a sufficient  number of its Common Shares) in connection with the
consummation  of any such  transaction  as may be  necessary  to assure that the
provisions  hereof shall  thereafter be applicable,  as nearly as reasonably may
be, in relation to its Common Shares thereafter deliverable upon the exercise of
the Rights;  and (v) the provisions of Section  11(a)(ii)  hereof shall be of no
effect following the first occurrence of any Section 13 Event.

                  (b)      "Principal Party" shall mean

                           (i)  in the  case  of any  transaction  described  in
         clause (x) or (y) of the first  sentence of Section 13(a)  hereof,  (A)
         the Person  that is the  issuer of any  securities  into  which  Common
         Shares of the  Company  are  converted,  changed or  exchanged  in such
         merger, consolidation or combination, or if there is more than one such
         issuer,  the issuer the Common Shares of which has the greatest  market
         value or (B) if no securities are so issued, the Person

                                     - 20 -

         that is the other  party to such  merger  (and  survives  the  merger),
         consolidation or combination (or if there is more than one such Person,
         the Person the Common  Shares of which has the greatest  value),  or if
         the other party to the merger  does not survive the merger,  the Person
         that does survive the merger  (including  the Company if it  survives);
         and

                           (ii) in the  case  of any  transaction  described  in
         clause (z) of the first sentence of Section  13(a),  the Person that is
         the party receiving the greatest portion of the assets or earning power
         transferred  pursuant to such  transaction or transactions  or, if each
         Person that is a party to such transaction or transactions receives the
         same portion of the assets or earning  power so  transferred  or if the
         Person  receiving  the greater  portion of the assets or earning  power
         cannot be determined, whichever of such Persons as is the issuer of the
         Common Shares having the greatest aggregate market value;

provided,  however,  that in any such  case,  (1) if the  Common  Shares of such
Person are not at such time and have not been  continuously  over the  preceding
12-month period  registered under Section 12 of the Exchange Act and such Person
is a direct or indirect  Subsidiary of another person the Common Shares of which
is and has been so  registered,  "Principal  Party"  shall  refer to such  other
Person;  (2) if the  Common  Shares of such  Person are not and have not been so
registered and such Person is a Subsidiary, directly or indirectly, of more than
one  Person,  the  Common  Shares  of two or more of which  are and have been so
registered,  "Principal  Party"  shall refer to whichever of such Persons is the
issuer of the Common Shares having the greatest  aggregate market value; and (3)
if the Common Shares of such Person are not and have not been so registered  and
such Person is owned,  directly or indirectly,  by a joint venture formed by two
or more Persons that are not owned, directly or indirectly,  by the same Person,
the rules set forth in (1) and (2) above  shall  apply to each of the  chains of
ownership  having an  interest  in such  joint  venture  as if such party were a
Subsidiary of both or all of such joint  venturers and the Principal  Parties in
each such chain shall bear the  obligations  set forth in this Section 13 in the
same ratio as their  direct or  indirect  interests  in such  Person bear to the
total of such interests.

                  (c) The  Company  shall not  consummate  any  Section 13 Event
unless the Principal Party shall have a sufficient  number of authorized  Common
Shares  which  have not been  issued or  reserved  for  issuance  to permit  the
exercise  in full of the Rights in  accordance  with this  Section 13 and unless
prior  thereto the  Company and such  Principal  Party shall have  executed  and
delivered  to the Rights  Agent a  supplemental  agreement  confirming  that the
requirements  of Sections  13(a) and (b) hereof  shall  promptly be performed in
accordance with their terms and that such Section 13 Event shall not result in a
default by the Principal  Party under this Agreement as the same shall have been
assumed by the  Principal  Party  pursuant to Sections  13(a) and (b) hereof and
further providing that, as soon as practicable after the date of such Section 13
Event, the Principal Party will:

                           (i) prepare and file a registration  statement  under
         the Act with respect to the Rights and the securities  purchasable upon
         exercise  of the  Rights on an  appropriate  form and will use its best
         efforts to cause such registration statement to (A) become effective as
         soon as practicable  after such filing and (B) remain effective (with a
         prospectus at all times meeting the  requirements of the Act) until the
         Expiration  Date  and  to  similarly   comply  with  applicable   state
         securities laws;

                           (ii) use its best efforts to list or obtain quotation
         of (or  continue  the  listing  or  quotation  of) the  Rights  and the
         securities  purchasable  upon  exercise  of the  Rights  on a  national
         securities exchange or automated quotation service;

<PAGE>




                           (iii)   will   deliver   to  holders  of  the  Rights
         historical financial statements for the Principal Party and each of its
         Affiliates  which  comply in all  respects  with the  requirements  for
         registration on Form 10 (or any successor form) under the Exchange Act;
         and

                           (iv) use its best  efforts  to obtain  waivers of any
         rights of first refusal or  preemptive  rights in respect of the Common
         Shares of the  Principal  Party  subject to purchase  upon  exercise of
         outstanding Rights.

The provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers. In the event that a Section 13 Event
shall occur at any time after the occurrence of a Section  11(a)(ii)  Event, the
Rights  which  have not  theretofore  been  exercised  shall  thereafter  become
exercisable in the manner described in Section 13(a).

                  (d)   Notwithstanding   anything  in  this  Agreement  to  the
contrary,  Section 13 shall not be  applicable  to a  transaction  described  in
subparagraph  (x) or (y) of Section 13(a) if (i) such transaction is consummated
with a Person or Persons  (or a wholly  owned  subsidiary  of any such Person or
Persons) who acquired Common Shares of the Company pursuant to a tender offer or
exchange offer for all  outstanding  Common Shares of the Company which complies
with the exception provided for in Section 11(a)(ii) hereof,  (ii) the price per
Common Shares of the Company  offered in such  transaction  is not less than the
price per Common Share paid to all holders of Common Shares of the Company whose
shares were purchased  pursuant to such tender offer or exchange offer and (iii)
the form of  consideration  being  offered  to the  remaining  holders of Common
Shares  pursuant to such  transaction  is the same as the form of  consideration
paid pursuant to such tender offer or exchange offer.  Upon  consummation of any
such transaction  contemplated by this Section 13(d), all Rights hereunder shall
expire.

         Section 14. Fractional Rights and Fractional Shares.

                  (a) The Company  shall not be required to issue  fractions  of
Rights,  except  prior to the  Distribution  Date as provided  in Section  11(i)
hereof, or to distribute Rights  Certificates which evidence  fractional Rights.
In lieu of such fractional Rights, there shall be paid to the registered holders
of the Rights  Certificates  with regard to which such  fractional  Rights would
otherwise  be  issuable,  an amount in cash  equal to the same  fraction  of the
current market value of a whole Right.  For purposes of this Section 14(a),  the
current  market value of a whole Right shall be the closing  price of the Rights
for the  Trading  Day  immediately  prior to the date on which  such  fractional
Rights would have been otherwise  issuable.  The closing price of the Rights for
any day  shall be the last sale  price,  regular  way,  or, in case no such sale
takes  place on such day,  the  average  of the  closing  bid and asked  prices,
regular  way,  in  either  case  as  reported  in  the  principal   consolidated
transaction  reporting  system with respect to securities  listed or admitted to
trading  on the New York  Stock  Exchange  or, if the  Rights  are not listed or
admitted to trading on the New York Stock Exchange, as reported in the principal
consolidated  transaction  reporting system with respect to securities listed on
the  principal  national  securities  exchange on which the Rights are listed or
admitted to  trading,  or if the Rights are not listed or admitted to trading on
any national  securities  exchange,  the last quoted price or, if not so quoted,
the average of the high bid and low asked prices in the over-the-counter market,
as reported by the Nasdaq  National  Market or the Nasdaq  Stock  Market or such
other  system  then in use or, if on any such date the  Rights are not quoted by
any such  organization,  the  average  of the  closing  bid and asked  prices as
furnished by a professional  market maker making a market in the Rights selected
by the Board (with the concurrence of a majority of the Continuing Trustees). If
on any such date no such market maker is

                                     - 22 -

<PAGE>



making a market  in the  Rights,  the fair  value of the  Rights on such date as
determined in good faith by the Board (with the concurrence of a majority of the
Continuing Trustees) shall be used.

                  (b) The Company  shall not be required to issue  fractions  of
Preferred  Shares  (other than  fractions  which are  integral  multiples of one
one-hundredth  of a  Preferred  Shares)  upon  exercise  of  the  Rights  or  to
distribute  certificates which evidence  fractional  Preferred Share (other than
fractions  which are  integral  multiples  of one  one-hundredth  of a Preferred
Share). In lieu of fractional  Preferred Shares that are not integral  multiples
of one one-hundredth of a Preferred Share, the Company may pay to the registered
holders of Rights  Certificates  at the time such Rights are exercised as herein
provided  an amount in cash equal to the same  fraction  of the  current  market
value of one  one-hundredth  of a Preferred  Share. For purposes of this Section
14(b), the current market value of one  one-hundredth of a Preferred Share shall
be  one  one-hundredth  of  the  closing  price  of a  Preferred  Share  or,  if
unavailable,  the  appropriate  alternative  price (in each  case as  determined
pursuant to Section  11(d)(ii)  hereof) for the Trading Day immediately prior to
the date of such exercise.

                  (c)  Following  the  occurrence  of a  Triggering  Event,  the
Company shall not be required to issue fractions of Common Shares of the Company
upon  exercise  of the  Rights  or to  distribute  certificates  which  evidence
fractional Common Shares of the Company.  In lieu of fractional Common Shares of
the  Company,   the  Company  may  pay  to  the  registered  holders  of  Rights
Certificates  at the time such Rights are exercised as herein provided an amount
in cash equal to the same fraction of the current market value of one (1) Common
Share of the Company.  For purposes of this Section  14(c),  the current  market
value of one Common Share shall be the closing  price of one Common Share or, if
unavailable,  the  appropriate  alternative  price (in each  case as  determined
pursuant to Section  11(d)(i)  hereof) for the Trading Day immediately  prior to
the date of such exercise.

                  (d) The  holder  of a Right by the  acceptance  of the  Rights
expressly  waives his right to receive any  fractional  Rights or any fractional
shares upon exercise of a Right, except as permitted by this Section 14.

         Section 15.  Rights of Action.  All rights of action in respect of this
Agreement,  except the rights of action  vested in the Rights Agent  pursuant to
Section 18 hereof, are vested in the respective registered holders of the Rights
Certificates (and, prior to the Distribution Date, the registered holders of the
Common  Shares  of the  Company);  and  any  registered  holder  of  any  Rights
Certificate  (or,  prior to the  Distribution  Date, of the Common Shares of the
Company),  without the consent of the Rights Agent or of the holder of any other
Rights  Certificate (or, prior to the Distribution Date, of the Common Shares of
the Company),  may, in his own behalf and for his own benefit,  enforce, and may
institute  and maintain any suit,  action or  proceeding  against the Company to
enforce,  or  otherwise  act in  respect  of, his right to  exercise  the Rights
evidenced  by such  Rights  Certificate  in the manner  provided  in such Rights
Certificate  and in  this  Agreement.  Without  limiting  the  foregoing  or any
remedies  available to the holders of Rights,  it is  specifically  acknowledged
that the  holders  of Rights  would not have an  adequate  remedy at law for any
breach of this  Agreement and shall be entitled to specific  performance  of the
obligations  hereunder  and  injunctive  relief  against  actual  or  threatened
violations  of  the  obliga  tions  hereunder  of any  Person  subject  to  this
Agreement.

         Section 16.  Agreement  of Rights  Holders.  Every holder of a Right by
accepting the same consents and agrees with the Company and the Rights Agent and
with every other holder of a Right that:


                                     - 23 -

<PAGE>



                   (a)  prior  to the  Distribution  Date,  the  Rights  will be
transferable  only in  connection  with the  transfer  of  Common  Shares of the
Company;

                  (b) after the Distribution  Date, the Rights  Certificates are
transferable  only on the registry  books of the Rights Agent if  surrendered at
the  principal  office  or  offices  of the  Rights  Agent  designated  for such
purposes,  duly endorsed or accompanied  by a proper  instrument of transfer and
with the appropriate forms and certificates fully executed;

                  (c)  subject to Section  6(a) and  Section  7(f)  hereof,  the
Company  and the  Rights  Agent may deem and treat  the  person in whose  name a
Rights  Certificate (or, prior to the Distribution  Date, the associated  Common
Shares  certificate)  is  registered  as the absolute  owner  thereof and of the
Rights evidenced thereby  (notwithstanding any notations of ownership or writing
on the Rights  Certificates or the associated Common Shares  certificate made by
anyone other than the Company or the Rights Agent) for all purposes  whatsoever,
and neither the Company nor the Rights  Agent,  subject to the last  sentence of
Section  7(e)  hereof,  shall be  required  to be  affected by any notice to the
contrary; and

                  (d)   notwithstanding   anything  in  this  Agreement  to  the
contrary,  neither the Company nor the Rights Agent shall have any  liability to
any holder of a Right or other  Person as a result of its  inability  to perform
any of its  obligations  under this  Agreement by reason of any  preliminary  or
permanent  injunction  or other  order,  decree or  ruling  issued by a court of
competent jurisdiction or by a governmental, regulatory or administrative agency
or commission,  or any statute,  rule, regulation or executive order promulgated
or enacted by any governmental  authority,  prohibiting or otherwise restraining
performance of such obligation; provided, however, the Company must use its best
efforts to have any such order, decree or ruling lifted or otherwise  overturned
as soon as possible.

         Section 17.  Rights  Certificate  Holder Not Deemed a  Shareholder.  No
holder, as such, of any Rights  Certificate  shall be entitled to vote,  receive
dividends  or be  deemed  for  any  purpose  the  holder  of the  number  of one
one-hundredths of a Preferred Share or any other securities of the Company which
may at any time be issuable on the exercise of the Rights  represented  thereby,
nor shall anything contained herein or in any Rights Certificate be construed to
confer upon the holder of any Rights Certificate,  as such, any of the rights of
a  shareholder  of the Company or any right to vote for the election of trustees
or upon any matter submitted to shareholders at any meeting thereof,  or to give
or withhold  consent to any trust  action,  or to receive  notice of meetings or
other actions affecting  shareholders (except as provided in Section 24 hereof),
or to receive dividends or subscription rights, or otherwise, until the Right or
Rights  evidenced  by such  Rights  Certificate  shall  have been  exercised  in
accordance with the provisions hereof.

         Section 18. Concerning the Rights Agent.

                  (a) The Company  agrees to pay to the Rights Agent  reasonable
compensation  for all services  rendered by it hereunder and, from time to time,
on demand of the Rights  Agent,  its  reasonable  expenses  and counsel fees and
disbursements  and  other  disbursements  incurred  in  the  administration  and
execution  of this  Agreement  and the exercise  and  performance  of its duties
hereunder.  The Company  also agrees to  indemnify  the Rights Agent for, and to
hold it harmless  against,  any loss,  liability,  or expense,  incurred without
gross  negligence,  bad faith or  willful  misconduct  on the part of the Rights
Agent,  for anything done or omitted by the Rights Agent in connection  with the
acceptance  and  administration  of this  Agreement,  including  the  costs  and
expenses of defending against any claim of liability in the premises.

<PAGE>




                  (b) The Rights  Agent  shall be  protected  and shall incur no
liability  for or in respect of any action  taken,  suffered or omitted by it in
connection with its administration of this Agreement in reliance upon any Rights
Certificate  or  certificate  for Common  Shares or for other  securities of the
Company,  instrument of assignment or transfer, power of attorney,  endorsement,
affidavit, letter, notice, direction, consent,  certificate,  statement or other
paper or  document  reasonably  believed  by it to be genuine  and to be signed,
executed and, where necessary,  verified or acknowledged by the proper Person or
Persons.

         Section 19. Merger or Consolidation or Change of Name of Rights Agent.

                  (a)  Any  corporation  into  which  the  Rights  Agent  or any
successor  Rights Agent may be merged or with which it may be  consolidated,  or
any corporation  resulting from any merger or  consolidation to which the Rights
Agent  or any  successor  Rights  Agent  shall be a  party,  or any  corporation
succeeding to the corporate trust or stock transfer business of the Rights Agent
or any successor Rights Agent,  shall be the successor to the Rights Agent under
this  Agreement  without the execution or filing of any paper or any further act
on the  part  of any  of  the  parties  hereto;  provided,  however,  that  such
corporation  would be eligible for appointment as a successor Rights Agent under
the provisions of Section 21 hereof.  If at the time such successor Rights Agent
shall  succeed  to the  agency  created  by this  Agreement,  any of the  Rights
Certificates shall have been countersigned but not delivered, any such successor
Rights Agent may adopt the  countersignature  of a predecessor  Rights Agent and
deliver such Rights  Certificates so  countersigned;  and if at that time any of
the Rights Certificates shall not have been countersigned,  any successor Rights
Agent  may  countersign  such  Rights  Certificates  either  in the  name of the
predecessor or in the name of the successor Rights Agent; and in all such cases,
such  Rights  Certificates  shall  have the full  force  provided  in the Rights
Certificates and in this Agreement.

                  (b) If at any  time  the  name of the  Rights  Agent  shall be
changed  and at  such  time  any of the  Rights  Certificates  shall  have  been
countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver Rights  Certificates so  countersigned;  and in
case  at  that  time  any  of  the  Rights  Certificates  shall  not  have  been
countersigned,  the Rights Agent may countersign such Rights Certificates either
in its prior name or in its changed  name;  and in all such  cases,  such Rights
Certificates  shall have the full force provided in the Rights  Certificates and
in this Agreement.

         Section 20. Duties of Rights  Agent.  The Rights Agent  undertakes  the
duties and  obligations  imposed by this Agreement upon the following  terms and
conditions,  by all of which the Company and the holders of Rights Certificates,
by their acceptance thereof, shall be bound:

                  (a) The Rights Agent may consult  with legal  counsel (who may
be legal counsel for the Company), and the opinion of such counsel shall be full
and complete  authorization  and protection to the Rights Agent as to any action
taken or omitted by it in good faith and in accordance with such opinion.

                  (b)  Whenever  in the  performance  of its  duties  under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter (including,  without limitation, the identity of any Acquiring Person and
the  determination  of the Current Market Price) be proved or established by the
Company prior to taking or suffering any action  hereunder,  such fact or matter
(unless other evidence in respect thereof be herein specifically prescribed) may
be deemed to be

                                     - 25 -

<PAGE>



conclusively  proved and established by a certificate  signed by the Chairman of
the Board,  the President,  any Vice  President,  the Treasurer or any Assistant
Treasurer of the Company and delivered to the Rights Agent; and such certificate
shall be full authorization to the Rights Agent for any action taken or suffered
in good faith by it under the provisions of this Agreement in reliance upon such
certificate.

                   (c) The Rights Agent shall be liable  hereunder  only for its
own gross negligence, bad faith or willful misconduct.

                  (d) The Rights  Agent  shall not be liable for or by reason of
any of the statements of fact or recitals  contained in this Agreement or in the
Rights  Certificates,  nor shall it be required to verify the same (except as to
its countersignature on such Rights  Certificates),  but all such statements and
recitals are and shall be deemed to have been made by the Company only.

                  (e) The Rights Agent shall not be under any  responsibility in
respect of the validity of this  Agreement or the execution and delivery  hereof
(except  the due  execution  hereof by the  Rights  Agent) or in  respect of the
validity or execution  of any Rights  Certificate  (except its  countersignature
thereon);  nor shall it be  responsible  for any  breach by the  Company  of any
covenant or condition  contained in this Agreement or in any Rights Certificate;
nor shall it be responsible for any adjustment  required under the provisions of
Section 11 or Section 13 hereof or responsible for the manner,  method or amount
of any such adjustment or the  ascertaining of the existence of facts that would
require  any such  adjustment  (except  with  respect to the  exercise of Rights
evidenced by Rights  Certificates  after actual notice of any such  adjustment);
nor  shall it by any act  hereunder  be  deemed  to make any  representation  or
warranty  as to the  authorization  or  reservation  of  any  Common  Shares  or
Preferred  Share  to  be  issued  pursuant  to  this  Agreement  or  any  Rights
Certificate or as to whether any Common Shares or Preferred  Share will, when so
issued, be validly authorized and issued, fully paid and nonassessable.

                  (f)  The  Company  agrees  that  it  will  perform,   execute,
acknowledge  and deliver or cause to be performed,  executed,  acknowledged  and
delivered  all such further and other acts,  instruments  and  assurances as may
reasonably be required by the Rights Agent for the carrying out or performing by
the Rights Agent of the provisions of this Agreement.

                  (g) The Rights  Agent is hereby  authorized  and  directed  to
accept instructions with respect to the performance of its duties hereunder from
the Chairman of the Board, the President,  any Vice President,  the Treasurer or
any Assistant Treasurer of the Company, and to apply to such officers for advice
or instructions  in connection  with its duties,  and it shall not be liable for
any action taken or suffered to be taken by it in good faith in accordance  with
instructions of any such officer.

                  (h) The Rights Agent and any stockholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Company or become pecuniarily interested in any transaction in
which the  Company  may be  interested,  or  contract  with or lend money to the
Company or otherwise  act as fully and freely as though it were not Rights Agent
under this Agreement. Nothing herein shall preclude the Rights Agent from acting
in any other capacity for the Company or for any other legal entity.

                  (i) The  Rights  Agent may  execute  and  exercise  any of the
rights or powers hereby vested in it or perform any duty hereunder either itself
or by or through  its  attorneys  or agents,  and the Rights  Agent shall not be
answerable or  accountable  for any act,  default,  neglect or misconduct of any
such attorneys or agents or for any loss to the Company  resulting from any such
act, default, neglect

                                     - 26 -

<PAGE>



or misconduct; provided, however, reasonable care was exercised in the selection
and continued employment thereof.

                  (j) No provision of this  Agreement  shall  require the Rights
Agent to expend or risk its own funds or otherwise incur any financial liability
in the  performance  of any of its duties  hereunder  or in the  exercise of its
rights if there shall be reasonable grounds for believing that repayment of such
funds  or  adequate  indemnification  against  such  risk  or  liability  is not
reasonably assured to it.

                  (k) If, with respect to any Rights Certificate  surrendered to
the Rights Agent for exercise or transfer,  the certificate attached to the form
of  assignment  or form of election to purchase,  as the case may be, has either
not been  completed or indicates  an  affirmative  response to clause 1 and/or 2
thereof, the Rights Agent shall not take any further action with respect to such
requested exercise or transfer without first consulting with the Company.

         Section 21. Change of Rights  Agent.  The Rights Agent or any successor
Rights Agent may resign and be discharged  from its duties under this  Agreement
upon 30 days'  notice in writing  mailed to the  Company,  and to each  transfer
agent of the Common Shares and Preferred Share, by registered or certified mail,
and to the holders of the Rights  Certificates by first-class  mail. The Company
may remove the Rights Agent or any  successor  Rights Agent upon 30 days' notice
in writing,  mailed to the Rights Agent or successor  Rights Agent,  as the case
may be, and to each transfer agent of the Common Shares and Preferred  Share, by
registered or certified  mail, and to the holders of the Rights  Certificates by
first-class  mail.  If the  Rights  Agent  shall  resign or be  removed or shall
otherwise become  incapable of acting,  the Company shall appoint a successor to
the Rights Agent.  If the Company shall fail to make such  appointment  within a
period  of 30 days  after  giving  notice of such  removal  or after it has been
notified  in writing of such  resignation  or  incapacity  by the  resigning  or
incapacitated  Rights Agent or by the holder of a Rights Certificate (who shall,
with such notice,  submit his Rights Certificate for inspection by the Company),
then any registered  holder of any Rights  Certificate may apply to any court of
competent  jurisdiction  for  the  appointment  of a  new  Rights  Agent.  If no
successor   Rights  Agent  shall  have  been  appointed   within  30  days  from
effectiveness  of such removal or resignation,  and no registered  holder of any
Rights  Certificates have applied pursuant to this Agreement for the appointment
of a new  Rights  Agent,  the  Company  shall  be  automatically  designated  as
successor  Rights Agent. Any successor  Rights Agent,  whether  appointed by the
Company  or by such a court,  shall be (a) a  corporation  organized  and  doing
business  under the laws of the  United  States  or of any  state of the  United
States so long as such  corporation  is  authorized  to do business as a banking
institution in such state, is in good standing, is authorized under such laws to
exercise  corporate  trust powers,  is subject to  supervision or examination by
federal  or state  authority  and has at the time of its  appointment  as Rights
Agent  a  combined  capital  and  surplus  of at  least  $100,000,000  or (b) an
Affiliate  of a  corporation  described  in clause (a) of this  sentence.  After
appointment,  the  successor  Rights Agent shall be vested with the same powers,
rights, duties and responsibilities as if it had been originally named as Rights
Agent  without  further  act or deed;  but the  predecessor  Rights  Agent shall
deliver and transfer to the successor Rights Agent any property at the time held
by it hereunder and shall execute and deliver any further assurance, conveyance,
act or deed necessary for the purpose.  Not later than the effective date of any
such  appointment,  the Company  shall file notice  thereof in writing  with the
predecessor  Rights Agent and each  transfer  agent of the Common Shares and the
Preferred  Share and shall mail a notice  thereof  in writing to the  registered
holders of the Rights  Certificates.  Failure to give any notice provided for in
this Section 21, however,  or any defect therein,  shall not affect the legality
or validity of the resignation or removal of the Rights Agent or the appointment
of the successor Rights Agent, as the case may be.

         Section 22. Issuance of New Rights Certificates. Notwithstanding any of
the provisions of this Agreement or of the Rights  Certificates to the contrary,
the Company may, at its option, issue new Rights Certificates  evidencing Rights
in such form as may be approved by the Board to reflect any adjustment or change
in the  Purchase  Price  and the  number  or kind or  class of  shares  or other
securities  or  property  purchasable  under  the  Rights  Certificates  made in
accordance  with the provisions of this  Agreement.  In addition,  in connection
with  the  issuance  or sale of  Common  Shares  of the  Company  following  the
Distribution  Date and prior to the redemption or expiration of the Rights,  the
Company  (a) shall,  with  respect to Common  Shares of the Company so issued or
sold  pursuant to the exercise of stock  options or under any  employee  plan or
arrangement,  or  upon  the  exercise,  conversion  or  exchange  of  securities
hereinafter  issued by the  Company,  and (b) may, in any other ease,  if deemed
necessary or appropriate by the Board,  issue Rights  Certificates  representing
the  appropriate  number of Rights in  connection  with such  issuance  or sale;
provided,  however,  that (i) no such Rights Certificate shall be issued if, and
to the extent that,  the Company  shall be advised by counsel that such issuance
would create a  significant  risk of material  adverse tax  consequences  to the
Company or the Person to whom such Rights  Certificate would be issued, and (ii)
no  such  Rights  Certificate  shall  be  issued  if,  and to the  extent  that,
appropriate  adjustment  shall  otherwise have been made in lieu of the issuance
thereof.

         Section 23. Redemption and Termination.

                  (a) The Board may (following the Stock  Acquisition Date, only
with the concurrence of a majority of the Continuing  Trustees),  at its option,
at any time  prior to the  earlier  of (i) the  Close of  Business  on the tenth
Business Day following the Stock  Acquisition Date (or, if the Stock Acquisition
Date shall have occurred  prior to the Record Date, the Close of Business on the
tenth Business Day following the Record Date) or (ii) the Final Expiration Date,
direct the Company to, and if so directed, the Company shall, redeem all but not
less than all of the then outstanding  Rights at a redemption price of $0.01 per
Right, as such amount may be appropriately  adjusted to reflect any stock split,
stock  dividend or similar  transaction  occurring  after the date hereof  (such
redemption  price  being  hereinafter  referred to as the  "Redemption  Price").
Notwithstanding anything contained in this Agreement to the contrary, the Rights
shall not be exercisable after the first occurrence of a Section 11(a)(ii) Event
until such time as the Company's right of redemption  hereunder has expired. The
Company may, at its option,  pay the Redemption Price in cash,  Common Shares of
the Company  (based on the Current Market Price of the Common Shares at the time
of  redemption)  or any other form of  consideration  deemed  appropriate by the
Board.

                  (b)  Immediately  upon  the  action  of the  Board  (with,  if
required, the concurrence of a majority of the Continuing Trustees) ordering the
redemption  of the  Rights,  evidence  of which  shall  have been filed with the
Rights Agent and without any further action and without any notice, the right to
exercise the Rights will terminate and the only right  thereafter of the holders
of Rights  shall be to  receive  the  Redemption  Price for each  Right so held.
Promptly  after the action of the Board  ordering the  redemption of the Rights,
the Company  shall give notice of such  redemption  to the Rights  Agent and the
holders  of the then  outstanding  Rights  by  mailing  such  notice to all such
holders at each holder's  last address as it appears upon the registry  books of
the Rights Agent or, prior to the  Distribution  Date, on the registry  books of
the  Transfer  Agent for the Common  Shares.  Any notice  which is mailed in the
manner herein provided shall be deemed given, whether or not the holder receives
the notice.  Each such notice of  redemption  will state the method by which the
payment of the Redemption Price will be made.

         Section 24. Notice of Certain Events.

                  (a) In case the Company shall  propose,  at any time after the
Distribution  Date, (i) to pay any dividend payable in stock of any class to the
holders of Preferred Shares or to make any other  distribution to the holders of
Preferred  Shares (other than a regular  quarterly cash dividend out of earnings
or  retained  earnings  of the  Company),  or (ii) to  offer to the  holders  of
Preferred  Shares  rights  or  warrants  to  subscribe  for or to  purchase  any
additional  Preferred  Shares  or  shares  of  stock of any  class or any  other
securities,  rights or options,  or (iii) to effect any  reclassification of its
Preferred Shares (other than a  reclassification  involving only the subdivision
of outstanding  Preferred Shares), or (iv) to effect any consolidation or merger
into or with any other  Person  (other  than a  Subsidiary  of the  Company in a
transaction which complies with Section 11(o) hereof),  or to effect any sale or
other transfer (or to permit one or more of its  Subsidiaries to effect any sale
or other transfer),  in one transaction or a series of related transactions,  of
more than 50% of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) to any other Person or Persons (other than the Company and/or
any of its Subsidiaries in one or more  transactions each of which complies with
Section 11(o) hereof), or (v) to effect the liquidation,  dissolution or winding
up of the  Company,  then,  in each such case,  the  Company  shall give to each
holder of a Rights  Certificate,  to the extent  feasible and in accordance with
Section 25 hereof,  a notice of such  proposed  action,  which shall specify the
record date for the purposes of such stock dividend or distribution of rights or
warrants,  or the date on which such  reclassification,  consolidation,  merger,
sale, transfer, liquidation,  dissolution or winding up is to take place and the
date of  participation  therein by the holders of the Preferred  Shares,  if any
such date is to be fixed,  and such notice  shall be so given in the case of any
action  covered by clause (i) or (ii) above at least  twenty  (20) days prior to
the record date for  determining  holders of the shares of Preferred  Shares for
purposes  of such  action,  and in the case of any such other  action,  at least
twenty (20) days prior to the date of the taking of such proposed  action or the
date of participation therein by the holders of the Preferred Shares,  whichever
shall be the earlier.

                  (b) In case any of the events  set forth in Section  11(a)(ii)
hereof shall occur,  then,  in any such case,  (i) the Company  shall as soon as
practicable  thereafter  give to each  holder  of a Rights  Certificate,  to the
extent  feasible  and in  accordance  with  Section 25  hereof,  a notice of the
occurrence of such event,  which shall specify the event and the consequences of
the event to holders of Rights  under  Section  11(a)(ii)  hereof,  and (ii) all
references  in the  preceding  paragraph  to  Preferred  Shares  shall be deemed
thereafter  to refer to Common  Shares of the Company  and/or,  if  appropriate,
other securities .

         Section 25. Notices. Notices or demands authorized by this Agreement to
be given or made by the Rights Agent or by the holder of any Rights  Certificate

Notices  or  demands  authorized  by this  Agreement  to be given or made by the
Company or the Rights  Agent to the holder of any  Rights  Certificate  (or,  if
prior to the  Distribution  Date,  to the  holder of  certificates  representing
Common  Shares of the Company)  shall be  sufficiently  given or made if sent by
first-class  mail,  postage prepaid,  addressed to such holder at the address of
such holder as shown on the registry books of the Company.

         Section 26. Supplements and Amendments.  Prior to the Distribution Date
and subject to the penultimate  sentence of this Section 26, the Company and the
Rights Agent shall,  if the Board so directs,  supplement or amend any provision
of  this  Agreement   without  the  approval  of  any  holders  of  certificates
representing Common Shares of the Company.  From and after the Distribution Date
and subject to the penultimate  sentence of this Section 26, the Company and the
Rights Agent shall, if the Board so directs,  supplement or amend this Agreement
without the approval of any holders of Rights  Certificates in order (i) to cure
any  ambiguity,  (ii) to correct or supplement  any provision  contained  herein
which may be defective or inconsistent with any other provisions  herein,  (iii)
to  shorten  or  lengthen  any  time  period  hereunder  (which   shortening  or
lengthening,  after the Stock Acquisition Date, shall require the concurrence of
a majority of such  Continuing  Trustees)  or (iv) to change or  supplement  the
provisions  hereunder  in any manner  which the  Company may deem  necessary  or
desirable and which shall not  adversely  affect the interests of the holders of
Rights Certificates (other than an Acquiring Person or an Affiliate or Associate
of any such Person);  provided,  that this Agreement may not be  supplemented or
amended to lengthen, pursuant to clause (iii) of this sentence (A) a time period
relating  to when the  Rights  may be  redeemed  or to modify  the  ability  (or
inability of the Board (with,  where required,  the concurrence of a majority of
the  Continuing  Trustees) to redeem the Rights,  in either case at such time as
the Rights are not then  redeemable  or (B) any other time  periods  unless such
lengthening is for the purpose of protecting, enhancing or clarifying the rights
of,  and/or the  benefits  to, the holders of Rights  (other  than an  Acquiring
Person or an Affiliate or Associate of any such Person).  Upon the delivery of a
certificate  from an  appropriate  officer of the Company  which states that the
proposed supplement or amendment is in compliance with the terms of this Section
26, the Rights Agent shall execute such supplement or amendment. Notwithstanding
anything contained in this Agreement to the contrary, no supplement or amendment
shall be made which changes the Redemption Price, the Final Expiration Date, the
Purchase  Price or the  number  of one  one-hundredths  of a share of  Preferred
Shares for which a Right is  exercisable.  Prior to the  Distribution  Date, the
interests of the holders of Rights shall be deemed coincident with the interests
of the holders of Common Shares of the Company.

         Section  27.  Successors.  All the  covenants  and  provisions  of this
Agreement  by or for the benefit of the  Company or the Rights  Agent shall bind
and inure to the benefit of their respective successors and assigns hereunder.

         Section  28.  Determinations  and  Actions  by the Board  etc.  For all
purposes of this  Agreement,  any  calculation of the number of Common Shares of
the Company  outstanding  at any  particular  time,  including  for  purposes of
determining the particular  percentage of such outstanding  Common Shares of the
Company of which any Person is the Beneficial Owner, shall be made in accordance
with  the  last  sentence  of  Rule  13d-3(d)(1)(i)  of the  General  Rules  and
Regulations under

                                     - 30 -

the Exchange Act. The Board (with, where  specifically  provided for herein, the
concurrence of Continuing Trustees) shall have the exclusive power and authority
to administer this Agreement and to exercise all rights and powers  specifically
granted  to the  Board  (with,  where  specifically  provided  for  herein,  the
concurrence of Continuing Trustees) or to the Company, or as may be necessary or
advisable in the administration of this Agreement including, without limitation,
the right and power to (a)  interpret the  provisions of this  Agreement and (b)
make all determinations  deemed necessary or advisable for the administration of
this Agreement  (including a determination to redeem or not redeem the Rights or
to amend the Agreement).  All such actions,  calculations,  interpretations  and
determinations  (including, for purposes of clause (y) below, all omissions with
respect  to the  foregoing)  which  are done or made by the Board  (with,  where
specifically provided for herein, the concurrence of Continuing  Trustees),  the
Continuing  Trustees,  the Outside Trustees or the Company in good faith,  shall
(x) be final,  conclusive  and binding on the  Company,  the Rights  Agent,  the
holders of the Rights and all other  parties and (y) not subject the Board,  the
Continuing  Trustees or the Outside  Trustees to any liability to the holders of
the Rights.

         Section 29. Exchange.

                  (a)  The  Board  (with  the   concurrence  of  the  Continuing
Trustees) may, at its option,  at any time after any Person becomes an Acquiring
Person,  exchange all or part of the then  outstanding  and  exercisable  Rights
(which shall not include  Rights that have become void pursuant to the provision
of Section 7(e) hereof) for Common Shares of the Company at an exchange ratio of
one Common Share of the Company per Right, appropriately adjusted to reflect any
stock split,  stock  dividend or similar  transaction  occurring  after the date
hereof  (such  exchange  ratio being  hereinafter  referred to as the  "Exchange
Ratio").  Notwithstanding  the  foregoing,  the Board shall not be  empowered to
effect such exchange at any time after any Person (other than an Exempt  Person)
becomes the Beneficial  Owner of 50% or more of the Common Shares of the Company
then outstanding.

                  (b)  Immediately  upon the  action of the Board  ordering  the
exchange of any Rights  pursuant to paragraph (a) of this Section 29 and without
any further action and without  notice,  the right to exercise such Rights shall
terminate  and the only right  thereafter of a holder of such Rights shall be to
receive that number of Common  Shares of the Company equal to the number of such
Rights held by such holder  multiplied by the Exchange Ratio.  The Company shall
promptly give public notice of any such exchange;  provided,  however,  that the
failure to give,  or any defect in, such notice shall not affect the validity of
such exchange.  The Company promptly shall mail a notice of any such exchange to
all of the  holders of such Rights at their last  addresses  as they appear upon
the registry  books of the Rights Agent or, prior to the  Distribution  Date, on
the registry books of the Transfer Agent for the Common Shares. Any notice which
is mailed in the manner herein  provided  shall be deemed given,  whether or not
the holder  receives  the notice.  Each such  notice of exchange  will state the
method by which the exchange of the Common Shares of the Company for Rights will
be  effected  and, in the event of any  partial  exchange,  the number of Rights
which will be exchanged.  Any partial  exchange shall be effected pro rata based
on the number of Rights  (other than Rights  which have become void  pursuant to
the provisions of Section 7(e) hereof) held by each holder of Rights.

                  (c) In any exchange  pursuant to this Section 29, the Company,
at its option, may substitute  Preferred Shares (or Equivalent Preferred Shares,
as such term is defined  in  Section  11(b)  hereof)  for  Common  Shares of the
Company  exchangeable for Rights,  at the initial rate of one one-hundredth of a
Preferred  Share (or  Equivalent  Preferred  Share) for each Common Share of the
Company, as appropriately adjusted to reflect adjustment in the voting rights of
the  Preferred  Shares  pursuant to Exhibit A hereto,  so that the fraction of a
share of Preferred Stock delivered in lieu of each

                                     - 31 -

<PAGE>



Common  Share of the  Company  shall have the same  voting  rights as one Common
Share of the Company.

                  (d) In the event that  there  shall not be  sufficient  Common
Shares of the Company  issued but not  outstanding or authorized but unissued to
permit any exchange of Rights as  contemplated  in accordance  with this Section
29, the Company  shall take all such  action as may be  necessary  to  authorize
additional  Common  Shares of the  Company  for  issuance  upon  exchange of the
Rights.

                  (e) The Company  shall not be required to issue  fractions  of
Common  Shares of the  Company  or to  distribute  certificates  which  evidence
fractional  Common  Shares of the  Company.  In lieu of such  fractional  Common
Shares of the  Company,  there  shall be paid to the  registered  holders of the
Rights  Certificates  with regard to which such fractional  Common Shares of the
Company would otherwise be issuable an amount in cash equal to the same fraction
of the current  market value of a whole  Common  Share of the  Company.  For the
purposes of this paragraph (e), the current market value of a whole Common Share
of the Company  shall be the closing  price of a Common Share of the Company or,
if unavailable,  the appropriate  alternative  price (in each case as determined
pursuant to Section  11(d)(i)  hereof) for the Trading Day immediately  prior to
the date on which the Board takes action  ordering an exchange  pursuant to this
Section 29.

         Section 30. Benefits of this Agreement. Nothing in this Agreement shall
be construed to give to any Person other than the Company,  the Rights Agent and
the  registered   holders  of  the  Rights   Certificates  (and,  prior  to  the
Distribution  Date,  registered holders of the Common Shares of the Company) any
legal or  equitable  right,  remedy  or claim  under  this  Agreement;  but this
Agreement shall be for the sole and exclusive benefit of the Company, the Rights
Agent and the registered  holders of the Rights  Certificates (and, prior to the
Distribution Date, registered holders of the Common Shares of the Company).

         Section  31.  Severability.   If  any  term,  provision,   covenant  or
restriction  of this Agreement is held by a court of competent  jurisdiction  or
other  authority  to be invalid,  void or  unenforceable,  the  remainder of the
terms, provisions,  covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected,  impaired or invalidated;
provided,  however,  that  notwithstanding  anything  in this  Agreement  to the
contrary, if any such term,  provision,  covenant or restriction is held by such
court or authority to be invalid,  void or unenforceable and the Board (with the
concurrence  of a majority of the  Continuing  Trustees)  determines in its good
faith  judgment that severing the invalid  language  from this  Agreement  would
adversely  affect  the  purpose  or  effect  of this  Agreement,  the  right  of
redemption  set forth in Section  23 hereof  shall be  reinstated  and shall not
expire until the Close of Business on the tenth  Business Day following the date
of such  determination  by the Board.  Without  limiting the  foregoing,  if any
provision of this Agreement  requiring that a determination be made by the Board
with  the  concurrence  of a  majority  of  the  Continuing  Trustees  or by the
Continuing  Trustees  or the Outside  Trustees  is held by a court of  competent
jurisdiction  or other  authority  to be invalid,  void or  unenforceable,  such
determination  shall then be made by the Board in accordance with applicable law
and the Company's  Declaration of Trust (as the same may be amended and restated
from time to time) and Bylaws.

         Section 32.  Governing Law.  Except as required by the law of the State
of Maryland governing  Maryland real estate investment  trusts,  this Agreement,
each Right and each Rights  Certificate issued hereunder shall be deemed to be a
contract made under the laws of the Commonwealth of Massachusetts  and shall for
all  purposes  be  governed  by and  construed  in  accordance  with the laws of
Massachusetts applicable to contracts made and to be performed entirely

                                     - 32 -

within Massachusetts,  including  Massachusetts  principles of conflicts of law.
The rights and duties of the Rights  Agent  hereunder  shall be  governed by the
laws of the Commonwealth of Massachusetts, including its principles of conflicts
of law.

         Section 33. Counterparts.  This Agreement may be executed in any number
of counterparts and each of such  counterparts  shall for all purposes be deemed
to be an original,  and all such counterparts shall together  constitute but one
and the same instrument.

         Section 34. Descriptive  Headings.  Descriptive headings of the several
Sections of this  Agreement  are  inserted  for  convenience  only and shall not
control or affect the meaning or construction of any of the provisions hereof.

                  IN WITNESS  WHEREOF,  the  parties  hereto  have  caused  this
Agreement  to be duly  executed  under seal as of the day and year  first  above
written.

                          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


                                                       

<PAGE>



         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

                                    Shares, if any.

                           (iii)    Unless  the  holders  of  Preferred   Shares
                                    shall,  during an existing  Default  Period,
                                    have  previously  exercised  their  right to

                                    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

                                    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

                                    the shareholders.

                           (iv)     In any Default Period, the holders of Common

                                    (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

                                    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

                                    vacant.  References in this paragraph (c) to
                                    Trustees   elected  by  the   holders  of  a
                                    particular  class of  Shares  shall  include

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

<PAGE>

                             

                           (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-

<PAGE>



         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-

<PAGE>



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.

         IN WITNESS  WHEREOF,  HOSPITALITY  PROPERTIES  TRUST has  caused  these
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___, 1997.

                                                                       Exhibit B


                                SUMMARY OF RIGHTS
                          TO PURCHASE PREFERRED SHARES


         On May 20, 1997, the Board of Trustees of Hospitality  Properties Trust
(the  "Company")  declared a dividend  distribution of one right for each of the
Company's  outstanding common shares of beneficial interest,  par value $.01 per
share (the "Common  Shares"),  to holders of record of the Common  Shares at the
close of business on June 20, 1997. Each Right entitles the registered holder to
purchase from the Company one  one-hundredth  of a preferred share of beneficial
interest,  par value $.01 per share, of the Company (the "Preferred  Shares") or
in certain  circumstances,  to receive  cash,  property,  Common Shares or other
securities of the Company, at a Purchase Price of $60 per one one-hundredth of a
Preferred Share, subject to adjustment (the "Rights"). The description and terms
of the  Rights  are set forth in a Rights  Agreement  (the  "Rights  Agreement")
between the Company and State Street Bank and Trust Company, as Rights Agent.

         Initially, the Rights will be attached to all certificates representing
the Common Shares and no separate Rights  Certificates will be distributed.  The
Rights will separate from the Common Shares and a  Distribution  Date will occur
upon the  earlier of (i) 10 business  days (or such later date as the  Company's
Board of Trustees may determine before a Distribution  Date occurs)  following a
public  announcement  by the  Company  that a person or group of  affiliated  or
associated  persons,  with  certain  exceptions  (an  "Acquiring  Person"),  has
acquired,  or has obtained the right to acquire,  beneficial ownership of 10% or
more of the outstanding  Common Shares (the date of such announcement  being the
"Share  Acquisition  Date") or (ii) 10 business  days (or such later date as the
Company's  Board of Trustees may determine  before a  Distribution  Date occurs)
following the commencement of a tender offer or exchange offer that would result
in a person becoming an Acquiring Person.

         Until the  Distribution  Date,  (i) the Rights will be evidenced by the
certificates  for Common Shares and will be transferred  with and only with such
Common  Share  certificates,  (ii)  Common  Share  certificates  will  contain a
notation  incorporating  the  Rights  Agreement  by  reference,  and  (iii)  the
surrender for transfer of any  certificates  for Common Shares  outstanding will
also  constitute  the transfer of the Rights  associated  with the Common Shares
represented by such certificates.

         The Rights are not  exercisable  until the  Distribution  Date and will
expire at the close of  business on May 31,  2007,  unless  earlier  redeemed or
exchanged by the Company as described below.

         As soon as practicable after the Distribution Date, Rights Certificates
will be mailed to  holders  of  record of the  Common  Shares as of the close of
business on the Distribution Date and, from and after the Distribution Date, the
separate Rights Certificates alone will represent the Rights.

         In the event (a "Flip-In  Event") a Person becomes an Acquiring  Person
(except pursuant to a tender or exchange offer for all outstanding Common Shares
at a price and on terms which a

                                                        

<PAGE>



majority of the Company's  Outside Trustees (as defined in the Rights Agreement)
determines to be fair to and otherwise in the best  interests of the Company and
its shareholders (a "fair offer")),  each holder of a Right will thereafter have
the right to receive, upon exercise of such Right, Common Shares (or, in certain
circumstances,  cash,  property or other  securities  of the  Company)  having a
Current Market Price (as defined in the Rights Agreement) equal to two times the
exercise  price of the  Right.  Notwithstanding  the  foregoing,  following  the
occurrence  of any  Flip-In  Event,  all  Rights  that are,  or  (under  certain
circumstances specified in the Rights Agreement) were, beneficially owned by any
Acquiring  Person (or by certain  related  parties) will be null and void in the
circumstances  set forth in the Rights  Agreement.  However,  Rights will not be
exercisable following the occurrence of any Flip-In Event until such time as the
Rights are no longer redeemable by the Company as set forth below.

         For  example,  at an exercise  price of $100 per Right,  each Right not
owned by an Acquiring Person (or by certain related parties) following a Flip-In
Event would entitle its holder to purchase $200 worth of Common Shares (or other
consideration, as noted above) for $100.

         In the event (a  "Flip-Over  Event")  that, at any time on or after the
Share  Acquisition  Date,  (i) the Company  shall take part in a merger or other
business combination  transaction (other than certain mergers that follow a fair
offer) and the  Company  shall not be the  surviving  entity or (ii) the Company
shall take part in a merger or other business  combination  transaction in which
the Common  Shares are changed or  exchanged  (other than  certain  mergers that
follow a fair  offer) or (iii) 50% or more of the  Company's  assets or  earning
power is sold or  transferred,  each  holder  of a Right  (except  Rights  which
previously have been voided, as set forth above) shall thereafter have the right
to receive,  upon exercise,  a number of shares of common stock of the acquiring
company  having a Current  Market Price equal to two times the exercise price of
the Right.  Flip-In Events and Flip-Over Events are collectively  referred to as
"Triggering Events."

         The Purchase  Price payable and the number of Preferred  Shares (or the
amount of cash,  property or other  securities)  issuable  upon  exercise of the
Rights are subject to  adjustment  from time to time to prevent  dilution (i) in
the  event  of  a  share   dividend  on,  or  a   subdivision,   combination  or
reclassification  of, the  Preferred  Shares,  (ii) if holders of the  Preferred
Shares are granted certain rights or warrants to subscribe for Preferred  Shares
or convertible securities at less than the Current Market Price of the Preferred
Shares or (iii) upon the  distribution  to holders  of the  Preferred  Shares of
evidences of indebtedness or assets (excluding regular quarterly cash dividends)
or of subscription rights or warrants (other than those referred to above).

         With certain  exceptions,  no adjustment in the Purchase  Price will be
required  until  cumulative  adjustments  amount to at least 1% of the  Purchase
Price. The Company is not required to issue fractional Preferred Shares upon the
exercise  of any Right or  Rights  evidenced  hereby.  In lieu  thereof,  a cash
payment may be made, as provided in the Rights Agreement.

         At any time until 10  business  days  following  the Share  Acquisition
Date, the Company may redeem the Rights in whole, but not in part, at a price of
$.01 per Right, payable, at the option of the Company, in cash, Common Shares or
other consideration as the Board of Trustees may determine. Immediately upon the
effectiveness of the action of the Company's Board of

                                       -2-

<PAGE>


Trustees  ordering  redemption of the Rights,  the Rights will terminate and the
only  right of the  holders  of  Rights  will be to  receive  the $.01 per Right
redemption price.

         Until a Right is exercised,  the holder thereof,  as such, will have no
rights as a shareholder of the Company, including, without limitation, the right
to vote or to receive  dividends.  While the distribution of the Rights will not
be taxable to shareholders or to the Company,  shareholders may,  depending upon
the circumstances,  recognize taxable income in the event that the Rights become
exercisable  for Common Shares (or cash,  property or other  securities)  of the
Company or for common stock of the acquiring company as set forth above.

         The terms of the Rights, other than key financial terms and the date on
which the Rights expire,  may be amended by the Board of Trustees of the Company
prior  to the  Distribution  Date.  Thereafter,  the  provisions  of the  Rights
Agreement  may be  amended  by the Board of  Trustees  only in order to cure any
ambiguity,  defect or  inconsistency,  to make  changes  which do not  adversely
affect the  interests  of  holders of Rights  (excluding  the  interests  of any
Acquiring  Person and certain other  related  parties) or to shorten or lengthen
any time period under the Rights Agreement; provided, however, that no amendment
to lengthen the time period  governing  redemption shall be made at such time as
the Rights are not redeemable.

         A copy of the Rights  Agreement has been filed with the  Securities and
Exchange Commission as an Exhibit to a Registration  Statement on Form 8-A dated
May 30,  1997. A copy of the Rights  Agreement is available  free of charge from
the Company or the Rights Agent. This summary description of the Rights does not
purport to be complete  and is  qualified  in its  entirety by  reference to the
Rights Agreement, which is incorporated herein by reference.

conditions of the Rights Agreement,  which terms,  provisions and conditions are
hereby  incorporated  herein by  reference  and made a part  hereof and to which

upon surrender at the principal office or offices of the Rights Agent designated
for such purpose,  may be exchanged  for another  Rights  Certificate  or Rights
Certificates  of like tenor and date evidencing  Rights  entitling the holder to
purchase a like aggregate  number of Preferred Shares as the Rights evidenced by
the Rights  Certificate or Rights  Certificates  surrendered shall have entitled
such holder to purchase.  If this Rights Certificate shall be exercised in part,
the holder shall be entitled to receive upon  surrender  hereof  another  Rights
Certificate or Rights Certificates for the number of whole Rights not exercised.
