                             INTRODUCTORY STATEMENT

     On June 30,  2003,  the  Borrower,  the  Lenders,  the  Agent  and the Swap
Provider  entered into the Credit  Agreement  pursuant to which the Lenders made
available to the Borrower a revolving credit facility in the aggregate principal
amount of $118,500,000.

     On or  about  the  date  hereof  the  Borrower  intends  to make a  capital
contribution and/or a loan to Belmar Realty Corporation,  a Delaware corporation
and a subsidiary of the Borrower ("BRC"), which such capital contribution and/or
loan proceeds will be used by BRC to make a capital  contribution  and/or a loan
to each of Brazos  Property  Trust  ("Brazos  JV") and Cimmaron  Property  Trust
("Cimmaron JV"), each a real estate investment trust organized under the laws of
the State of Maryland  (Brazos JV and Cimmaron JV,  collectively,  the "JVs") in
which BRC owns 100% of the outstanding  Class A common shares  (representing 80%
of the total outstanding  common shares) and ProLogis  ("ProLogis") owns 100% of
the outstanding Class B common shares (representing 20% of the total outstanding
common  shares),  which such capital  contribution  and/or loan proceeds will be
used by each of the JVs to make a capital contribution and/or a loan to ProLogis
Six Rivers Limited  Partnership,  a Delaware limited partnership ("Six Rivers"),
which such capital  contribution and/or loan proceeds will be used by Six Rivers
to acquire certain commercial real estate from Keystone Property Trust.

     In  order  to  make  the  necessary   funds   available  for  such  capital
contributions   and/or  loans  the  Borrower  has  requested  that  the  Lenders
temporarily increase the amount available under the revolving credit facility by
$213,500,000 to an aggregate principal amount of $332,000,000.
