Item 5.  Other Events

         A. Sale of Trust Preferred  Securities.  On June 18, 2001, we priced an
underwritten  public offering of one million 10.125% Trust Preferred  Securities
(the "Trust Preferred  Securities") of our subsidiary,  SNH Capital Trust I (the
"Trust").  Each Trust Preferred  Security has a liquidation amount of $25, which
was also the public offering price. The Trust Preferred  Securities,  along with
common  securities which the Trust is issuing to us or one of our  subsidiaries,
will represent the beneficial interest in the assets of the Trust. Distributions
on the Trust  Preferred  Securities  will be  payable  quarterly,  beginning  on
September 15, 2001, at the rate of 10.125% of the stated  liquidation amount per
year, or approximately $2.53 per Trust Preferred Security per year. We have also
granted to the  underwriters  an option to purchase an additional  150,000 Trust
Preferred  Securities from the Trust at the public offering price within 30 days
from June 18, 2001 to cover overallotments.

         The Trust will invest the  proceeds of the offering and of its issuance
of common securities to us in $25,773,200 of our Junior Subordinated  Debentures
(the "Junior Subordinated Debentures"). If the overallotment option is exercised
in full,  the Trust will invest the proceeds of the additional  Trust  Preferred
Securities and of additional  common  securities in an additional  $3,866,000 of
Junior  Subordinated  Debentures.  We  expect  to use  the net  proceeds  of the
offering of the Trust  Preferred  Securities,  after our payment of underwriting
commissions  and other expenses in connection with the offering and the issuance
of the Junior Subordinated Debentures, to repay outstanding borrowings under our
revolving credit facility.

         The Junior Subordinated Debentures bear interest at the rate of 10.125%
per year, payable quarterly in arrears,  unless deferred, and mature on June 15,
2041.  We have the right to redeem the  Junior  Subordinated  Debentures  before
their  maturity  any time on or after June 15,  2006 in whole or in part,  or in
whole  at  any  time  within  180  days  following  the  occurrence  and  during
continuance  of  certain   changes  in  tax  or  investment   company  laws  and
regulations.  The  redemption  price in any such  case is 100% of the  principal
amount of Junior Subordinated Debentures being redeemed, plus accrued and unpaid
interest.

         The Trust is required to redeem all of the outstanding  Trust Preferred
Securities when the Junior Subordinated  Debentures are repaid at maturity.  The
Trust is also  obligated to use the cash it receives from the  redemption of the
Debentures to redeem a proportionate  amount of the Trust  Preferred  Securities
and its common securities.

         We will guarantee (the  "Guarantee") the payments of all amounts due on
the Trust  Preferred  Securities to the extent the Trust has funds available for
payment of those  amounts.  The Guarantee does not cover payments when the Trust
does not have sufficient funds.

         We have the  right on one or more  occasions  to  defer  the  quarterly
interest payments on the Junior Subordinated Debentures for up to 20 consecutive
quarterly  periods,  in any event not extending  beyond the maturity date of the
Junior  Subordinated  Debentures.  We may also elect to shorten or lengthen  any
deferral  period,  but we may not begin a new deferral period until we have paid
all accrued  interest from the previous  deferral  period.  If we defer interest
payments  on the  Junior  Subordinated  Debentures,  the Trust  will also  defer
distribution on the Trust  Preferred  Securities.  Any deferred  interest on the
Junior Subordinated Debentures will accrue additional


interest  an  annual  rate  of  10.125%,  compounded  quarterly,  to the  extent
permitted by law,  and as a result,  any  deferred  distributions  on the Junior
Subordinated  Debentures will accumulate additional amounts at an annual rate of
10.125%, compounded quarterly, to the extent permitted by law.

         During any period  during  which we defer  interest  payments on Junior
Subordinated  Debentures,  we are not  permitted  and our  subsidiaries  are not
permitted to:

         o        declare or pay any dividends or  distributions  on, or redeem,
                  purchase,  acquire or make a liquidation  payment with respect
                  to, any of the our shares of beneficial interest;

         o        make any payment of  principal  of or interest or premium,  if
                  any,   on,  or  repay,   repurchase   or  redeem  any  of  our
                  indebtedness  that  ranks on a parity  with or  junior  to the
                  Junior Subordinated Debentures in right of payment; or

         o        make any  guarantee  payments with respect to any guarantee we
                  have  given  of  indebtedness  of  any  subsidiary,   if  such
                  guarantee  ranks  on  parity  with  or  junior  to the  Junior
                  Subordinated Debentures in right of payment.

         The foregoing restrictions do not apply to any of the following:

         o        dividends or distributions payable solely in our common shares
                  or equivalent securities,

         o        any  reclassification of any class of our shares of beneficial
                  interest,

         o        any   declaration  of  a  dividend  in  connection   with  the
                  implementation  of certain  shareholder  rights protection and
                  similar plans described in the supplemental indenture relating
                  to the Junior Subordinated Debentures ("Rights Plans"),

         o        the issuance of any of our shares of beneficial interest under
                  any Rights Plan or the  redemption or repurchase of any rights
                  distributed pursuant to a Rights Plan,

         o        payments under the Guarantee, or

         o        purchases  of  our  common  shares  or  equivalent  securities
                  related to common  shares or  equivalent  securities or rights
                  issued  under  any of our  benefit  plans  for  our  trustees,
                  officers, employees, consultants or advisors or the directors,
                  officers, employees, consultants or advisors of our advisor.

         Our  obligations  under  the  Junior  Subordinated  Debentures  and the
Guarantee are unsecured obligations which are subordinate and junior in right of
payment to our senior  indebtedness.  For that purpose,  our senior indebtedness
includes:

         o        any of our  indebtedness  for  borrowed  or  purchased  money,
                  whether or not evidenced by bonds, debentures,  notes or other
                  written instruments,

                                      -2-


         o        our  obligations  for  reimbursement  under letters of credit,
                  banker's acceptances,  security purchase facilities or similar
                  facilities issued for our account,

         o        any of our  indebtedness or other  obligations with respect to
                  commodity contracts (including but not limited to contracts in
                  the spot,  forward and markets,  options,  and  contracts  for
                  differences),   interest  rate  commodity  and  currency  swap
                  agreements,  cap, floor and collar  agreements,  currency spot
                  and  forward  contracts,   and  other  similar  agreements  or
                  arrangements  designed  to  protect  against  fluctuations  in
                  commodity prices, currency exchange or interest rates, and

         o        any  guarantees,  endorsements  (other than by  endorsement of
                  negotiable  instruments  for collection in the ordinary course
                  of  business)  or  other  similar  contingent  obligations  in
                  respect of obligations  of others of a type  described  above,
                  whether or not such obligation is classified as a liability on
                  a balance sheet prepared in accordance with generally accepted
                  accounting principles,

in each case described above, whether now outstanding or hereafter incurred, and
excluding  (1)  obligations  ranking on a parity  with the  Junior  Subordinated
Debentures or ranking junior to the Junior  Subordinated  Debentures and (2) our
obligations to trade creditors.

         The Trust  Preferred  Securities  have been approved for listing on the
New York Stock Exchange, and we expect that trading will commence within 30 days
following the date on which they are first issued.

         THIS REPORT CONTAINS FORWARD LOOKING  STATEMENTS  WITHIN THE MEANING OF
THE  PRIVATE  SECURITIES  REFORM ACT OF 1995,  INCLUDING  THOSE  RELATING TO THE
SETTLEMENT  AND  LISTING AND TRADING OF THE TRUST  PREFERRED  SECURITIES.  THESE
FORWARD LOOKING  STATEMENTS ARE BASED UPON OUR PRESENT  EXPECTATIONS,  BUT THESE
