ITEM 8.01. OTHER EVENTS

(a)      CHANGE OF TRANSFER AGENT

         On December 13, 2004,  we changed the transfer  agent for our shares of
beneficial  interest from  EquiServe  Trust  Company,  N.A. to Wells Fargo Bank,
National  Association,  or Wells  Fargo.  Wells Fargo now serves as our transfer
agent,   registrar  and  dividend   disbursing  agent  and  also  acts  as  plan
administrator of our Dividend Reinvestment and Cash Purchase Plan. In connection
with the change, we amended our Dividend  Reinvestment and Cash Purchase Plan in
certain respects. A copy of the current Dividend  Reinvestment and Cash Purchase
Plan is furnished attached to this Report as Exhibit 99.1.  Additionally,  Wells
Fargo now is successor  Rights Agent under the Renewed Rights  Agreement,  dated
March 10, 2004, relating to our shareholder protection rights plan.

(b)      SUPPLEMENTARY FEDERAL INCOME TAX CONSIDERATIONS

         The following summary of federal income tax considerations  supplements
and updates the more detailed  description of these matters  appearing under the
caption  "Federal Income Tax  Considerations"  of Item 1 of our Annual Report on
Form 10-K for the year ended December 31, 2003 (our "Annual Report"). Sullivan &
Worcester  LLP,  Boston,  Massachusetts,  has rendered a legal  opinion that the
discussion in the portion of our Annual  Report  captioned  "Federal  Income Tax
Considerations",  as supplemented by the discussion in this Report,  is accurate
in all material  respects and fairly  summarizes  the federal  income tax issues
discussed  in those  sections,  and the  opinion of counsel  referred to in such
portion of our Annual Report,  as supplemented by the discussion in this Report,
represents  Sullivan & Worcester LLP's opinion on those subjects.  Specifically,
subject to  qualifications  and  assumptions  contained in its  opinion,  in our
Annual  Report  and in this  Report,  Sullivan &  Worcester  LLP has given us an
opinion to the effect that we have been  organized and have  qualified as a REIT
under the Internal  Revenue Code of 1986,  as amended (the "IRC"),  for our 1987
through  2003  taxable  years,  and that  our  current  investments  and plan of
operation will enable us to continue to meet the requirements for  qualification
and taxation as a REIT under the IRC.

         On October 22, 2004,  the American Jobs Creation Act of 2004 (the "2004
Act") became law. The 2004 Act,  which is generally  effective for taxable years
beginning in 2005,  contains a number of provisions  applicable to REITs.  These
provisions  make it easier  for REITs to satisfy  some of the  income  tests and
asset tests more  particularly  described in our Annual  Report,  and to prevent
terminations  of REIT status due to  inadvertent  violations  of  technical  tax
requirements. Significant REIT provisions of the 2004 Act are summarized below.

         The  2004  Act  expands,  for  purposes  of the 10%  asset  value  test
described in our Annual Report,  the "straight  debt"  securities safe harbor to
include, on a retroactive basis, among other items (a) certain rental agreements
in which payment is to be made in subsequent  years,  (b) any  obligation to pay
rents from real property,  (c) securities  issued by governmental  entities that
are not  dependent  in whole or in part on the  profits  of or  payments  from a
nongovernmental entity, and (d) any security issued by another REIT.

         The 2004 Act excludes  from the 95% gross income test  described in our
Annual Report any income arising from "clearly  identified" hedging transactions
that are  entered  into by a REIT,  or certain  subsidiary  entities,  to manage
interest  rate,  price,  or currency  fluctuations  with  respect to  borrowings
incurred or to be  incurred by the REIT to acquire or carry real estate  assets.
In  general,  for a  hedging  transaction  to be  "clearly  identified"  (a) the
transaction  must be identified as a hedging  transaction  before the end of the
day on which it is entered  and (b) the



risks being hedged must be  identified  generally  within 35 days after the date
the transaction is entered.

         Two relief  provisions  are contained in the 2004 Act for violations of
the 5% asset test or the 10% vote or value asset tests  described  in our Annual
Report.  A REIT that fails the 5% value  test or the 10% vote or value  tests at
the close of any quarter  without  curing such failure  within 30 days after the
close of such  quarter is excused  if (a) the value of the  assets  causing  the
failure does not exceed the lesser of 1% of the total value of the REIT's assets
at the end of the relevant  quarter or $10,000,000 and (b) within 6 months after
the last day of the quarter in which the REIT identifies the failure, either the
REIT  disposes of the assets  causing the failure or otherwise  satisfies the 5%
value or 10% vote or value asset tests. The 2004 Act also provides an additional
relief  provision  pursuant  to which a REIT that  fails the 5% value or the 10%
vote or value asset tests in a taxable year may  nevertheless  qualify as a REIT
if (a) the REIT  provides the IRS with a  description  of each asset causing the
failure,  (b) the failure was due to reasonable  cause and not willful  neglect,
(c) the REIT pays a tax equal to the  greater of (i) $50,000 or (ii) the highest
rate of corporate tax imposed (currently 35%) on the net income generated by the
assets  causing  the  failure  during the period of the failure and (d) within 6
months  after  the last day of the  quarter  in which  the REIT  identifies  the
failure, either the REIT disposes of the assets causing the failure or otherwise
satisfies the 5% value or 10% vote or value asset tests.

         Under the 2004 Act, capital gain dividends  deductible by us in respect
of our 2005  taxable year and beyond,  and  received by a non-U.S.  shareholder,
will be subject to the taxation and  withholding  regime  applicable to ordinary
income dividends (and the branch profits tax will not apply),  provided that (1)
the capital gain  dividends  are received with respect to a class of shares that
is regularly  traded on an established  securities  market located in the United
States and (2) the foreign  shareholder  does not own more than 5% of that class
of  shares  at any time  during  the  taxable  year in which  the  capital  gain
dividends are received. As such, qualifying non-U.S. shareholders will no longer
be subject to FIRPTA  withholding on capital gain dividends,  and will no longer
be required to file U.S.  federal income tax returns in respect of their capital
gain dividends.

         U.S.  shareholders  who  realize a loss on the sale or  exchange of our
shares may be required to file IRS Form 8886, Reportable  Transaction Disclosure
Statement,  if the loss  meets or exceeds  certain  thresholds;  for  individual
taxpayers,  the  threshold is  $2,000,000  for a loss in a single  taxable year.
Substantial  penalties  may be  imposed  under  the 2004 Act if Form 8886 is not
properly  filed.  U.S.  shareholders  should  consult  with  their tax  advisors
regarding Form 8886 filing requirements.
