Funds From Operations ("FFO") is a non-GAAP  financial  measurement used by real
estate  investment  trusts 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 an appropriate measure
of performance  of an equity REIT because,  along with cash flows from operating
activities, financing activities and investing activities, it provides investors
with an understanding of our ability to incur and service debt, and make capital
expenditures. 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)  Includes  approximately  $472 in amortization  expense for the three months
     ended June 30, 2005 and 2004 and approximately $944 in amortization expense
     for the six months ended June 30, 2005 and 2004 for the amortization of the
     above-market  lease  intangible  asset  of the San  Tomas  Technology  Park
     acquisition pursuant to Statement of Financial Accounting Standard ("SFAS")
     No. 141, "Business Combinations."

(2)  Includes  approximately $361 and $714 in amortization expense for the three
     months ended June 30, 2005 and 2004,  respectively,  and approximately $801
     and $1,291 in  amortization  expense for the six months ended June 30, 2005
     and 2004, respectively, for the amortization of in-place lease value of the
     San Tomas  Technology Park  acquisition  pursuant to Statement of Financial
     Accounting Standard ("SFAS") No. 141, "Business Combinations."

     outstanding into the Company's common stock.

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

(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.
