Funds From Operations ("FFO") is a non-GAAP  financial  measurement used by real
estate investment trusts ("REITs") to measure and compare operating performance.
As defined by NAREIT,  FFO represents net income (loss) before minority interest
of unit  holders  (computed  in  accordance  with  GAAP,  accounting  principles
generally accepted in the United States of America), excluding gains (or losses)
from  debt  restructuring  and  sales of  property,  plus  real  estate  related
depreciation  and  amortization  (excluding  amortization of deferred  financing
costs and  depreciation  of non-real  estate assets) and after  adjustments  for
unconsolidated  partnerships and joint ventures.  Management considers FFO to be
an  appropriate  supplemental  measure of the Company's  operating and financial
performance  because  when  compared  year over year,  it reflects the impact to
operations  from trends in  occupancy  rates,  rental  rates,  operating  costs,
general and administrative  expenses and interest costs, providing a perspective
not immediately apparent from net income. In addition,  management believes that
FFO provides useful information about the Company's  financial  performance when
compared  to other  REITs  since FFO is  generally  recognized  as the  industry
standard for reporting the operations of REITs.  FFO should not be considered as
an alternative for net income as a measure of  profitability or is it comparable
to cash flows  provided by operating  activities  determined in accordance  with
GAAP. FFO is not comparable to similarly  entitled items reported by other REITs
that do not define them exactly as we define FFO.

     $1,189 in amortization expense for the nine months ended September 30, 2007

     intangible asset pursuant to Statement of Financial Accounting Standard No.

(4)  The  minority  interest  for third  parties  has been  deducted  from total
     minority interest in calculating FFO.

(5)  Average  monthly  rental  revenue  per square foot has been  determined  by
     taking the cash base rent for the period divided by the number of months in
     the period,  and then  divided by the average  occupied  square feet in the
     period.
