Item 6.  Contracts, Arrangements, Understandings or Relationships With Respect 
         to Securities of the Issuer.

         HRP has formed no definitive intent to sell the Shares or any portion
thereof. However, depending upon its continuing review of its investments and
various other facts, HRP may in the future desire, subject to any applicable
securities laws, to sell all or a portion of the Shares. HPT has registered the
offer and sale of the Shares under the Securities Act of 1933, as amended (the
"Securities Act"), pursuant to a registration statement on Form S-3 (No.
333-109658). That registration statement became effective on October 24, 2003.
In connection with the registration statement, HRP and HPT entered into a
Registration Agreement (the "Registration Agreement"). Under the Registration
Agreement, HPT agreed to, among other things, file the registration statement
and use reasonable efforts to effect the registration of the Shares and HRP,
among other things, agreed to pay all expenses incurred by HPT relating to the
registration and any sale of the Shares. HPT also agreed to indemnify HRP
against certain liabilities, including liabilities under the Securities Act and,
alternately, to contribute to payments that HRP may be required to make as a
result of these liabilities.
