<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">During
2009 and 2008, we acquired 47 MOB properties for an aggregate purchase price of
approximately $562.0 million.&#160; During
2009 and 2008, we recorded impairment charges of $11.7 million and $1.4
million, respectively, related to these MOBs, determined as follows:</font></p>

Pharmaceuticals, the sole tenant of one MOB that we acquired in 2008, filed for
bankruptcy.&#160; Prior to the bankruptcy
filing (and for several months thereafter) all rents were received from EPIX in
a timely fashion.&#160; Nonetheless, because
we believed the bankruptcy filing to be an impairment indicator, we performed
an impairment analysis which resulted in a charge of approximately $7.5 million
in 2009.&#160; The charge represents the

leased to Fallon Clinic,&nbsp;Inc., or Fallon, a major healthcare services
provider in central Massachusetts, under one combined lease.&#160; After we acquired these properties, Fallon
stated to us its desire to consolidate medical practices located in certain
smaller MOBs into its larger facilities.&#160;
After some negotiations, we and Fallon agreed that we would consider
offering certain leased properties for sale in arms length transactions to
third parties, and the proceeds of these sales would be placed in escrow and
used for improvements to the properties which remain subject to the lease,
without any reduction in the total rent payable to us by Fallon.&#160; During 2008, we and Fallon received an offer
for one of these properties that was less than our carrying value for this
property which we determined to accept.&#160;
As a result, we recorded an impairment charge of $1.4 million to reduce
the carrying value of this property to its fair value; and this property was
then sold in 2009.&#160; During 2009, we
reviewed the carrying values of four additional properties included in the
Fallon combination lease which we also had agreed with Fallon to consider
selling and, as a result of that review, we recorded an additional impairment
charge of approximately $4.2 million to reduce the carrying values for three of
these four properties to their fair values.</font></p>

Star Quality Care,&nbsp;Inc., or Five Star, was the lessee of the three and

property.&#160; If we identify an indicator of
impairment for a property leased to a particular tenant and if warranted by the

particular tenant for possible impairment.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We
determined the 2009 and 2008 impairment charges for the three and seven
residential care facilities leased to Five Star as follows:</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

facilities to Five Star pursuant to four leases, each for multiple
facilities.&#160; These leases provide that if
Five Star shall reasonably determine that it is no longer economically
practical to continue to operate a facility and if we and Five Star cannot
agree on an alternative use for such facility, then Five Star may market such
facility for sale to a third party.&#160; We
have the right to accept or reject any bona fide offer to purchase such
facility received by Five Star from a person having the financial capacity to implement
the terms of such offer.&#160; If we accept an
offer and such a facility is subsequently sold we receive the net proceeds of
the sale.&#160; If we reject the offer,
although we retain ownership of the facility, the applicable lease terminates
with respect to such facility. When a facility is sold or if&nbsp;we reject an
offer from a third party</font></p>

<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">as described above, the rent due to us from Five Star with respect to
such lease is reduced by a formula amount (usually 8-10% per annum times the
net proceeds we receive or were projected to receive if we rejected such offer)
set in the lease.&#160; The impairment charges
recorded in 2009 and 2008 reflect the differences between our carrying values
and the fair values for facilities Five Star identified as no longer
economically practical to operate during the respective periods.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We
do not believe our agreements with Fallon or the undertakings with Five Star to
offer for sale certain of the leased MOBs or residential care facilities are
indications that necessarily should cause us to evaluate other properties
leased to these tenants for possible impairments.&#160; We nonetheless did so and determined that no
further impairment charges were appropriate with respect to properties leased
to these tenants at that time.&#160; We have
no other properties leased to EPIX Pharmaceuticals.</font></p>

<p style="margin:0in 0in .0001pt .5in;"><i><font size="2" face="Times New Roman" style="font-size:10.0pt;font-style:italic;">We periodically evaluate our properties for impairment. Impairment
indicators may include declining tenant occupancy, weak or declining tenant
profitability, cash flow or liquidity, our decision to dispose of an asset
before the end of its estimated useful life and legislative, market or industry
changes that could permanently reduce the value of a property. If indicators of
impairment are present, we evaluate the carrying value of the related property
by comparing it to the expected future undiscounted cash flows to be generated
from that property. If the sum of these expected future cash flows is less than
the carrying value, we reduce the net carrying value of the property to its
estimated fair value</font></i><font size="2" style="font-size:10.0pt;">.&#160; During
2009, we recorded impairment charges of $15,530 related to 11 properties,
including one of the properties classified as held for sale and one property
sold in November&nbsp;2009, to reduce the carrying value of these assets to
their estimated fair value, less costs to sell.&#160;
During 2008, we recorded impairment charges of $8,379 related to four
properties, including the two properties classified as held for sale, to reduce
the carrying value of these assets to their estimated fair value, less costs to
sell.&#160; During 2007, we recorded an
impairment charge of $1,400 related to one property classified as held for sale
to reduce the carrying value of this asset held for sale to its estimated fair
value, less costs to sell.</font></p>
