Liabilities or any other indebtedness, obligations or liabilities of Borrower or

calculation with respect to such representations and covenants at any time other
than in  connection  with  the  delivery  of a Real  Property  Statement  or the
delivery of the  certificate  of a Responsible  Officer  under  Section  5.2(b);
provided further that even if not required to make such calculations, nothing in
this  Section  1.3(a)  shall  be  construed  to  in  any  way  limit  Borrower's
obligations to satisfy all such representations and covenants in accordance with
their terms.

                  (b) Administrative Agent shall calculate the Equivalent Amount
of Loans  denominated  in GBP: (i) after any  Borrowing  Date on which Loans are
made such that the aggregate  principal amount of Loans outstanding  exceeds 75%
of the Commitments and if requested by Agent or if  Administrative  Agent in the
reasonable  exercise  of its  judgment  considers  it  desirable  to  make  such
calculation  to  monitor  compliance  by  Borrower  with the limits set forth in
Section  2.1, on the final  Business Day of each  Interest  Period for each Loan
denominated in GBP or otherwise as often as  Administrative  Agent  considers it
desirable or necessary to make such calculation and  Administrative  Agent shall
notify  Borrower  and  Agent  if,  based  on such  calculation,  Borrower  is in

outstanding  principal amount of Loans denominated in GBP or whether  prepayment
of the Loans is  necessary as required by Section  2.8(e);  (ii) on any proposed
Borrowing  Date  to  determine  whether,  after  giving  effect  to  a  proposed
borrowing, Borrower will be in compliance with such requirements of Section 2.1;
and (iii) on any  proposed  continuation/conversion  date under  Section  2.5 to
determine whether, after giving effect to such proposed continuation/conversion,
Borrower will be in compliance with such  requirements of Section 2.1;  provided
that any failure by  Administrative  Agent to make such  calculations or provide
the  information  under this Section 1.3(b) shall not affect the  obligations of
Borrower  to comply  with the limits set forth in Section  2.1 or  otherwise  to
satisfy all representations and covenants made by it in this Agreement.

                  SECTION 2.AMOUNT AND TERMS OF REVOLVING LOANS

                  2.1. Revolving Loans.

                  a. Each Lender severally (and not jointly) agrees,  subject to
the terms and conditions  hereof,  to continue the Existing Loans outstanding on
the  Effective  Date,  to make Loans to  Borrower  from time to time  during the
period from the Effective Date to and including the Final Borrowing Date, and to
maintain its Loans outstanding to Borrower on the Final Borrowing Date from such
date until the Termination Date, up to an aggregate amount  (including,  without
limitation, the amount of any Existing Loans) or the Equivalent Amount in GBP at
any one time not exceeding its Pro Rata Share of the aggregate  Commitments  (as
defined below) to be used for the purposes  identified in Section 2.11; provided
that in no event  shall  the  aggregate  outstanding  principal  amount of Loans
denominated in GBP at any time exceed the Equivalent  Amount of $100,000,000 (as
determined in accordance with Section 1.3(b)). Each Loan hereunder shall be made
by Lenders in accordance with their respective Pro Rata Share. Upon satisfaction
of the  conditions set forth in Section 4, (i) all loans  outstanding  under the
Existing Loan Agreement as of, and at the time of, the Effective Date ("Existing
Loans")  and all rights  relating  to the  Existing  Loans and all other  rights
arising under the Existing Loan  Agreement and all documents  relating  thereto,
except to the extent specifically amended and restated by this Agreement,  shall
be assigned (without any further action or authorization  being required) by the
lenders  under the Existing  Loan  Agreement to the Lenders  proportionately  to
their  respective  Pro  Rata  Shares  of  the  Commitments   without   recourse,
representation  or warranty (except for  representations  and warranties made in
this Section 2.1(a)) of any nature,  express or implied,  by any such lender and
such  Existing  Loans shall be continued and deemed to be Loans for all purposes
under this Agreement and (ii) each Lender shall pay to Administrative  Agent its
Pro Rata Share of the Existing  Loans or, if less,  the amount by which such Pro
Rata Share exceeds its outstanding  Existing Loans (if any), for distribution to
the lenders  under the Existing Loan  Agreement  that are not Lenders and to the
other Lenders that have funded such Loans, in accordance  with their  respective
Commitments,  and each  Lender's  share of the Existing  Loans shall be adjusted
accordingly.  In connection with such assignment, each Lender shall be deemed to
represent  and  warrant to each other  Lender that (i) it is, and will be on the
Effective  Date,  prior to the  assignment  of its  interests  pursuant  to this
Section 2.1(a),  the legal and beneficial  owner of the interests being assigned
and such interests are, and will be on the Effective Date, free and clear of any
adverse  claim  and  (ii) the  total  aggregate  principal  amount  and  accrued
interest,  fees and other  amounts due to such Lender  under the  Existing  Loan
Agreement on the Effective  Date are as set forth on Schedule 3 annexed  hereto.
Any amounts of accrued  interest,  commitment  fees or other amounts (other than
principal)  owed  (whether or not  presently due and payable) by Borrower to the
lenders  under or in respect of the Existing  Loans shall,  as of the  Effective
Date, be deemed to be due

                                      -35-
<PAGE>

and payable to the lenders under the Existing Loan Agreement.  The  continuation
of the Existing Loans hereunder  shall not be deemed to be a repayment  thereof,
and Borrower shall not be required to deliver any notice of prepayment or notice
of  borrowing  or to  satisfy  any  condition  relating  to  minimum  amounts of
prepayments  or minimum  amounts of  borrowings  hereunder  with respect to such
continuance of the Existing Loans.

                  b. Each  Lender's  commitment  to make and  maintain  Loans to
Borrower pursuant to this Section 2.1 is herein called its "Commitment" and such
commitments of all Lenders in the aggregate are herein called the "Commitments".
The original  amount of each Lender's  Commitment is set forth opposite its name
on  Schedule  1  annexed  hereto  and  the  aggregate  original  amount  of  the
Commitments  is  $500,000,000;  provided  that  up to an  Equivalent  Amount  of
$100,000,000  may be  made  in  Loans  denominated  in  GBP  (as  determined  in
accordance  with  Section  1.3(b));  provided  further  that the  amount  of the
Commitments  shall be reduced from time to time by the amount of any  reductions
thereto  made  pursuant to Section 2.7 (with a  proportionate  reduction  of the
amount  of the  Commitments  otherwise  available  for the  borrowing  of  Loans
denominated in GBP);  provided  further that Lenders shall have no obligation to
make or  maintain  Loans  hereunder  to the extent any such Loan would cause the
aggregate  amount of the Loans  then  outstanding  to  exceed  the  Commitments;
provided further that Lenders shall have no obligation to make or maintain Loans
denominated  in GBP  hereunder  to the  extent  any such  Loan  would  cause the
aggregate amount of the Loans  denominated in GBP then outstanding to exceed the
Equivalent  Amount of  $100,000,000  (as  determined in accordance  with Section
1.3(b).

                  c. Each Lender's  Commitment  shall expire on the  Termination
Date and all Loans and all other  amounts  owed  hereunder  with  respect to the
Loans and the Commitments shall be paid in full no later than that date.

                  d. Subject to the other terms and conditions hereof,  Borrower
may borrow under this Section 2.1,  repay Loans in accordance  with Section 2.10
or prepay  Loans in  accordance  with  Section 2.8 and  reborrow  the amounts so
repaid under this Section 2.1.

                  2.2.  Notes;  Maturity Date. The Loans of each Lender pursuant
hereto shall be evidenced by, and be repayable with interest in accordance  with
the terms of, a promissory note of Borrower substantially in the form of Exhibit
A, with  appropriate  insertions,  payable  to the  order of such  Lender in the
principal   amount  of  the  Commitment  of  such  Lender   (together  with  any
replacement,  modification,  renewal or  substitution  thereof,  individually  a
"Note" and collectively,  the "Notes"),  which shall be dated the Effective Date
and be duly  completed,  executed and  delivered by Borrower.  The Loans of each
Lender  pursuant  hereto shall be made and  maintained by such Lender's  Lending
Office(s) as designated by such Lender from time to time. All outstanding  Loans
and each of the Notes shall mature and Borrower shall repay the

                                      -36-
<PAGE>
outstanding  principal  amount of such Loans and the Notes in full together with
all unpaid  interest  accrued  thereon on the  Termination  Date (or  earlier as
hereinafter  provided) (or if such day is not a Business Day, the next preceding
Business Day) all in accordance  with Section  2.10(b),  and shall be subject to
payment  and  prepayment  as  provided  in Section  2.8  hereof.  Each Lender is
authorized to endorse at any time the date and amount of each Loan or conversion
or continuation  thereof,  the date and amount of each payment of principal with
respect to its Loans and  whether  its Loans are Base Rate  Loans,  Eurocurrency
Loans or Alternate  Rate Loans,  on the schedule  annexed to and  constituting a
part of such Lender's  Note,  which  endorsement  shall  constitute  prima facie
evidence of the accuracy of the information endorsed.

                  In lieu of delivering the above-described Notice of Borrowing,
Borrower may give  Administrative  Agent  telephonic  notice  (which  telephonic
notice shall be followed immediately with a notice by facsimile telecopy) by the
time specified for a Notice of Borrowing above;  provided that such notice shall
be  promptly  confirmed  in  writing by  delivery  of a Notice of  Borrowing  to
Administrative  Agent on or  before  the  applicable  Borrowing  Date;  provided
further that in the event of a  discrepancy  between a Notice of  Borrowing  and
such telephonic notice, the telephonic notice shall govern.  Except as otherwise
provided in Sections 2.13 and 2.14, a Notice of Borrowing (or telephonic  notice
in lieu thereof as provided above) shall be  irrevocable,  and Borrower shall be
bound to make the borrowing specified in such Notice of Borrowing (or telephonic
notice in lieu thereof as provided above) in accordance therewith.

                  None of Agent,  Administrative Agent or any Lender shall incur
any liability to any Person  (including  Borrower or any of its Subsidiaries) in
acting upon any telephonic notice referred to above that Administrative Agent or
Agent believes in good faith to have been given by a duly authorized  officer or
other Person  authorized to borrow on behalf of Borrower or otherwise  acting in
good  faith  under this  Section  2.3,  and upon  funding of Loans by Lenders in
accordance with this Agreement  pursuant to any such telephonic  notice Borrower
shall have effected the borrowing of such Loans hereunder.

                  b. All Loans  under  this  Agreement  shall be made by Lenders
simultaneously  and  proportionately  to their respective Pro Rata Shares of the
Commitments,  it being  understood  that no Lender shall be responsible  for any
default by any other  Lender in that  other  Lender's  obligation  to make Loans
requested  hereunder  nor  shall the  Commitment  of any  Lender  to make  Loans
requested  hereunder  be  increased or decreased as a result of a default by any
other  Lender  in  that  other  Lender's  obligation  to  make  Loans  requested
hereunder.  Promptly  after  receipt  by  Administrative  Agent of a  Notice  of
Borrowing  pursuant  to Section  2.3(a) (or  telephonic  notice in lieu  thereof
followed  immediately with a notice by facsimile  telecopy) and in any event not
later than 2:00 p.m. (New York time) on the preceding  Business Day (in the case
of Base Rate Loans) or at least three Business Days (in the case of Eurocurrency
Loans) in advance of the proposed  Borrowing  Date,  Administrative  Agent shall
notify each  Lender of the  relevant  details of the  proposed  borrowing.  Each
Lender shall make the amount of its Loan available to  Administrative  Agent, in
immediately available funds, at the account specified by Administrative Agent to
the Lenders,  not later than 11:00 A.M.  (New York time) on the  Borrowing  Date
specified in the applicable Notice of Borrowing.  Upon satisfaction or waiver of
the  applicable   conditions  precedent  specified  in  Sections  4.1  and  4.2,
Administrative Agent shall make the proceeds of such Loans 

                                      -38-
<PAGE>
available to Borrower on such Borrowing Date by causing an amount of immediately
available   funds  equal  to  the  proceeds  of  all  such  Loans   received  by
Administrative  Agent from  Lenders to be credited to the account  specified  by
Borrower in the Notice of Borrowing.

                  Unless  Administrative  Agent shall have been  notified by any
Lender  prior to the  Borrowing  Date for any Loans  that such  Lender  does not
intend to make  available to  Administrative  Agent the amount of such  Lender's
Loan  requested  on such  Borrowing  Date (and any such notice  shall be without
prejudice   to  any  rights  of  Borrower   against   such  Lender   hereunder),
Administrative  Agent may assume that such Lender has made such amount available
to Administrative  Agent on such Borrowing Date and Administrative Agent may, in
its sole discretion, but shall not be obligated to, make available to Borrower a
corresponding amount on such Borrowing Date. If such corresponding amount is not
in fact made available to  Administrative  Agent by such Lender,  Administrative
Agent shall be entitled to recover such corresponding amount on demand from such
Lender  together with interest  thereon,  for each day from such  Borrowing Date
until the date such amount is paid to Administrative  Agent, at the Base Rate in
the case of Loans  denominated  in U.S.  Dollars or at the Alternate GBP Rate in
the  case  of  Loans  denominated  in GBP.  If such  Lender  does  not pay  such
corresponding  amount  forthwith upon  Administrative  Agent's demand  therefor,
Administrative   Agent  shall  promptly   notify  Borrower  and  Borrower  shall
immediately pay such corresponding  amount to Administrative Agent together with
interest  thereon,  for each day from such  Borrowing  Date  until the date such
amount is paid to  Administrative  Agent,  at the Base Rate in the case of Loans
denominated  in U.S.  Dollars or at the  Alternate GBP Rate in the case of Loans
denominated  in GBP.  Nothing in this Section 2.3 shall be deemed to relieve any
Lender from its obligation to fulfill its Commitments  hereunder or to prejudice
any rights that  Borrower may have against any Lender as a result of any default
by such Lender hereunder.

                  2.4. Interest.

                  a. Generally. Each Loan shall be a Eurocurrency Loan or a Base
Rate Loan as selected by Borrower initially at the time a Notice of Borrowing is
given pursuant to Section 2.3(a) or as selected  pursuant to Section 2.5 (or, in
the case of any Existing Loans, as in effect on the Effective Date),  except for
any portion of a Eurocurrency  Loan which is converted to an Alternate Rate Loan
pursuant  to  Section  2.13 or 2.14.  Loans  shall bear  interest  on the unpaid
principal  amount  thereof  from the date made (or, in the case of any  Existing
Loans,  from the  Effective  Date) to  maturity  (whether  by  accelerations  or
otherwise), at the interest rates specified as follows:

                  (i) in the case of a  Eurocurrency  Loan,  at an interest rate
         per annum for and during each  Interest  Period  equal to the LIBO Rate
         for such Interest Period plus the Applicable Margin in effect from time
         to time;
                                      -39-
<PAGE>
                  (ii) in the case of a Base Rate Loan,  at an interest rate per
         annum  equal to the Base  Rate in  effect  from  time to time  plus the
         Applicable Margin in effect from time to time; and

                  (iii) in the case of an  Alternate  Rate Loan  (including  any
         Alternate  GBP Rate Loan),  at an interest  rate per annum equal to the
         Alternate Rate in effect from time to time plus the  Applicable  Margin
         in effect from time to time,

                  plus, in the case of any Loan denominated in GBP and made by a
Lender subject to such requirements, Mandatory Liquid Asset Costs.

Borrower  shall  pay  interest  on the  unpaid  principal  amount  of the  Loans
outstanding  from time to time, in arrears,  (i) on each Interest  Payment Date,
(ii) on the Termination  Date, (iii) in the currency required by Section 2.10(b)
and (iv) in  accordance  with Section  2.4(b) (where  applicable).  In addition,
Borrower shall pay accrued interest on the principal amount of any Loans prepaid
in accordance with Section 2.8 on the date of any such prepayment.

                  b. Default Interest.  If Borrower shall default in the payment
of the  principal  of or interest  on any portion of a Loan or any other  amount
becoming due  hereunder or under any of the Loan  Documents,  Borrower  shall on
demand from time to time pay  interest  (to the extent  permitted  by law in the
case of interest on overdue interest) on such defaulted amount accruing from and
including the date of such default (without reference to any period of grace) up
to and including the date of actual payment  (after as well as before  judgment)
at a rate per  annum  which is the sum of (i) two  percent  (2%)  plus  (ii) the
greatest of the LIBO Rate,  the  Alternate  Rate or the Base Rate plus (iii) the
Applicable  Margin.  Interest  under this  Section  2.4(b) shall be payable upon
demand.

                  c. Interest Determination.  Upon determining the LIBO Rate for
each  Interest  Period,  the  Alternate  Rate for any period or the Base Rate in
effect from time to time,  Administrative  Agent shall promptly  notify Borrower
and Lenders thereof by telephone  (confirmed promptly in writing) or in writing.
Such  determination  shall,  in the absence of manifest error, be conclusive and
binding upon Borrower and the Lenders.

                  2.5.    Duration    of    Interest    Period;     Notice    of
Continuation/Conversion.

                  a.  Borrower  may,   pursuant  to  the  applicable  Notice  of
Borrowing or Notice of  Continuation/Conversion,  as the case may be,  select an
Interest Period to be applicable to each Eurocurrency Loan.

                                      -40-
<PAGE>
                  b.  Subject  to the  provisions  of  Sections  2.13 and  2.14,
Borrower  shall  have the  option  (i) to convert at any time all or any part of
outstanding Base Rate Loans to Eurocurrency Loans or (ii) upon the expiration of
any Interest  Period  applicable to  Eurocurrency  Loans, to continue all or any
portion of such Loans as  Eurocurrency  Loans or convert  all or any  portion of
such Loans to Base Rate Loans,  as the case may be, and the succeeding  Interest
Period(s) of such  continued  Loans shall  commence on the most recent  Interest
Payment Date  therefor;  provided  that Loans may be continued  as, or converted
into,  Eurocurrency Loans with a particular Interest Period only in an aggregate
amount equal to $1,000,000 and integral  multiples of $500,000 in excess of that
amount if the Loans are to be denominated in U.S. Dollars or a minimum aggregate
amount of GBP 1,000,000 and integral  multiples of GBP 500,000 in excess of that
amount if the  Loans are to be  denominated  in GBP (but  subject  always to the
determinations  described  in Section  1.3(b) and the limits in Section  2.1 for
Loans  denominated  in GBP);  provided  further that  Eurocurrency  Loans or any
portion  thereof may only be  converted  into Base Rate Loans on the  expiration
date of the Interest Period(s) applicable thereto; and provided further that (i)
no  event  has  occurred  and is  continuing  or would  result  from  such  Loan
continuation/conversion that would constitute a Default or Event of Default, and
(ii) the  representations  and warranties  contained in Section 3 shall be true,
correct  and  complete  in all  material  respects  on  and  as of the  proposed
continuation/conversion date to the same extent as though made on and as of that
date unless  stated in such  section to relate to a specific  earlier  date,  in
which  case such  representations  and  warranties  shall be true,  correct  and
complete in all material  respects as of such earlier date. All  conversions and
continuations of Loans shall be made  simultaneously  and on a pro rata basis by
the Lenders in accordance with their respective Pro Rata Shares.

                  Borrower shall deliver a Notice of  Continuation/Conversion to
Administrative  Agent no later  than  11:00  A.M.  (New York City time) at least
three Business Days in advance of the proposed  continuation/conversion date (in
the case of a conversion to, or a  continuation  of,  Eurocurrency  Loans) or at
least three  Business  Days in advance of the proposed  conversion  date (in the
case of a conversion  to Base Rate Loans).  A Notice of  Continuation/Conversion
shall  specify (i) the proposed  continuation/conversion  date (which shall be a
Business Day), (ii) the amount of the Loans to be continued/converted, (iii) the
nature  of  the  proposed  continuation/conversion,   (iv)  in  the  case  of  a
continuation of, or conversion to,  Eurocurrency  Loans, the requested  Interest
Period,  (v) that  the  representations  and  warranties  contained  in the Loan
Documents  are true,  correct and accurate in all material  respects to the same
extent as  though  made on and as of the date of such  Notice  of  Continuation/
Conversion  

                                      -41-
<PAGE>
unless  stated in such Loan  Documents to relate to a specific  earlier date, in
which  case such  representations  and  warranties  shall be true,  correct  and
complete in all  material  respects as of such  earlier  date,  and (vi) that no
event  has  occurred  and is  continuing  or  would  result  from  the  proposed
continuation/conversion  that would constitute a Default or Event of Default. In
lieu  of  delivering  the  above-described  Notice  of  Continuation/Conversion,
Borrower may give  Administrative  Agent telephonic notice by the time specified
for  delivery of a Notice of  Continuation/Conversion  above  (which  telephonic
notice  shall be  followed  immediately  with a notice by  facsimile  telecopy);
provided   that  in  the   event  of  a   discrepancy   between   a  Notice   of
Continuation/Conversion and such telephonic notice, such telephonic notice shall
govern.

                  Promptly after receipt by Administrative  Agent of a Notice of
Continuation/Conversion  pursuant  to this  Section  2.5 (or  telephonic  notice
followed immediately with a notice by facsimile telecopy),  and in any event not
later than 2:00 p.m. (New York time) at least three  Business Days in advance of
the proposed  continuation/conversion  date,  Administrative  Agent shall notify
each Lender of the relevant details of the proposed continuation/conversion.

                  None of Agent,  Administrative Agent or any Lender shall incur
any liability to any Person  (including  Borrower) in acting upon any telephonic
notice  referred to above that  Administrative  Agent or Agent  believes in good
faith to have been given by a duly authorized officer or other person authorized
to act on behalf of  Borrower or for  otherwise  acting in good faith under this
Section 2.5, and upon the continuation  and/or conversion (as applicable) of any
Loan in accordance with this Agreement  pursuant to any such telephonic  notice,
Borrower shall have effected a continuation  and/or  conversion (as  applicable)
hereunder of such Loan.

                  Except as  otherwise  provided  in Sections  2.13 and 2.14,  a
Notice of  Continuation/Conversion  (or telephonic notice in lieu thereof) shall
be irrevocable from and after the giving thereof, and Borrower shall be bound to
effect a continuation and/or conversion (as applicable) in accordance therewith.

                  2.6. Fees.

                  a. Borrower shall pay to Administrative  Agent for the account
of each Lender,  in  accordance  with its Pro Rata Share of the  Commitments,  a
facility fee in an amount equal to the Applicable Facility Fee Percentage of the
average daily balance of such Lender's  Commitment in respect of each  quarterly
period  during  the  period  from the date  hereof  to but  excluding  the Final
Borrowing Date.  Borrower shall pay to  Administrative  Agent for the 

                                      -42-
<PAGE>
account  of  each  Lender,  in  accordance  with  its  Pro  Rata  Share  of  the
Commitments,  a facility fee in an amount equal to the  Applicable  Facility Fee
Percentage of the average  daily  balance of such  Lender's  Loans in respect of
each  quarterly  period during the period from the Final  Borrowing  Date to but
excluding the Final Repayment Date. Such fees shall be calculated  quarterly and
be payable in arrears on (x) the last Business Day of March, June, September and
December of each year until the Final Repayment Date and (y) the Final Repayment
Date,  and accrue from the Effective  Date to and excluding the Final  Repayment
Date and be payable in U.S. Dollars as required by Section 2.10(b).

                  b. Borrower shall pay to Administrative  Agent such other fees
in the amounts and at the times  separately  agreed upon  between  Borrower  and
Agent or between Borrower, Agent and Administrative Agent.

                  2.7.  Termination or Reduction of  Commitment.  Borrower shall
have the right,  upon not less than five Business Days' notice to Administrative
Agent,  to terminate the  Commitments  or, from time to time, to reduce pro rata
the  amount  of the  Commitments,  to the  extent,  in  either  case,  that  the
Commitments are undrawn.  Any such reduction shall be in an amount of $1,000,000
or any integral  multiple  thereof and shall reduce  permanently  the  aggregate
amount of the Commitments then in effect, with a proportionate  reduction of the
amount  of the  Commitments  otherwise  available  for the  borrowing  of  Loans
denominated in GBP.

                  2.8. Optional Prepayments; Mandatory Prepayments.

                  a. Subject to Sections  2.8(f) and 2.15,  Borrower may, at its
option,  prepay  any  Loans on any  Business  Day in  whole or in part,  without
premium,  upon at least three Business Days', in the case of Eurocurrency Loans,
or one Business Day's,  in the case of Base Rate Loans,  prior written notice to
Administrative  Agent,  specifying  the  amount of  prepayment.  Each  notice of
prepayment  pursuant  to this  clause (a) shall be  irrevocable  and the payment
amount  specified in such notice shall be due and payable on the date  specified
in the currency  required by Section 2.10(b),  together with accrued interest to
such date on the Loans and all  amounts  (if any)  payable  pursuant  to Section
2.15.  Partial  prepayments of the Loans pursuant to this clause (a) shall be in
an aggregate  principal  amount of  $1,000,000  (or GBP  1,000,000)  or integral
multiples of $500,000 (or GBP 500,000) in excess of that amount.

                  b. In the  event  of any  sale  or  other  disposition  of any
interest in any Property, any Lease termination,  or any other event giving rise
to Net  Property  Proceeds or Net Mortgage  Proceeds,  on the earlier of (x) the
final Business Day of the first  Interest  Period to expire after the closing of
such sale or other disposition,  or, if such closing occurs at a time when there
are no Eurocurrency  Loans  outstanding,  on the final Business Day of the

                                      -44-
<PAGE>
month during which such closing occurs,  or (y) the date of an Event of Default,
Borrower  shall apply an amount equal to all of such Net  Property  Proceeds and
Net  Mortgage  Proceeds  (other  than any amount  thereof  required  and used to
satisfy  Indebtedness secured by a Lien, not inconsistent with the terms of this
Agreement,  on the relevant  Properties or Mortgage Interests) to the prepayment
of the Loans;  provided that (i) with respect to a particular  transaction  or a
related  series of  transactions  giving  rise to Net  Property  Proceeds or Net
Mortgage  Proceeds,  prepayment  of the Loans  shall be  required  from such Net
Property  Proceeds  or Net  Mortgage  Proceeds  only to the extent that the same
exceed $5,000,000; (ii) that no prepayment shall be required in respect of Loans
denominated in GBP to the extent the aggregate  outstanding  principal amount of
such Loans does not exceed the Allowed Value of Eligible Properties and Eligible
Mortgages in respect of Properties  located in the United Kingdom  acquired with
or funded with GBP;  and (iii)  Borrower  shall  provide  written  notice to the
Administrative  Agent  on the  date  of such  closing  of  such  sale  or  other
disposition  in excess of  $5,000,000  which  sets  forth the amount of such Net
Property Proceeds and Net Mortgage Proceeds.

                  c. In the event of any (i) public or private offering by or on
behalf of  Borrower  of debt or equity  securities  issued by  Borrower  or (ii)
incurrence by Borrower of Indebtedness to one or more financial institutions, on
the earlier of (x) the final Business Day of the first Interest Period to expire
after the closing of such issuance or incurrence, or if such closing occurs at a
time when there are no Eurocurrency Loans outstanding, on the final Business Day
of the month during which such  closing  occurs,  or (y) the date of an Event of
Default, Borrower shall apply all Net Securities/Debt Proceeds arising from such
offering  or  incurrence  to the  prepayment  of the Loans or, at the  option of
Borrower, to the prepayment of other Indebtedness of Borrower outstanding on the
Effective Date;  provided that (i) no prepayment shall be required in respect of
Loans  denominated  in GBP to the extent  the  aggregate  outstanding  principal
amount of such Loans does not exceed the Allowed  Value of  Eligible  Properties
and Eligible  Mortgages in respect of Properties  located in the United  Kingdom
acquired with or funded with GBP; and (ii) Borrower shall provide written notice
to the  Administrative  Agent on the date of such  closing of such  issuance  or
incurrence which sets forth the amount of such Net Securities/Debt Proceeds.

                  d. The Loans shall be subject to certain mandatory prepayments
pursuant to and upon the occurrence of the events described in the provisions of
Sections 2.13 and 2.14.

                  e. If at any time the  principal  balance of the Loans exceeds
the  Commitments,  Borrower  shall  promptly (and in any event no later than two
Business Days after becoming aware thereof) repay Loans to the extent  necessary
to reduce the aggregate  outstanding  principal amount thereof to an amount that
is equal to or less than the Commitments.  If at any time the principal  balance
of the Loans  denominated in GBP exceeds the Equivalent  Amount of  $100,000,000

                                      -44-
<PAGE>
(as determined in accordance with Section 1.3(b)),  Borrower shall promptly (and
in any event no later than two Business Days after becoming aware thereof) repay
Loans  denominated  in GBP to the  extent  necessary  to  reduce  the  aggregate
outstanding  principal amount thereof to an amount that is equal to or less than
the  Equivalent  Amount in GBP of  $100,000,000;  provided  that,  so long as no
Default or Event of Default has occurred and is  continuing,  any such repayment
of the  Loans  denominated  in GBP  may be  made  at the  end of the  applicable
Interest Periods on condition that Borrower deposits with  Administrative  Agent
cash in an amount  equal to the amount of the  required  prepayment  at the time
otherwise required for prepayment (such amounts to be held as cash collateral by
Administrative  Agent  pending such  repayment on terms  satisfactory  to Agent,
Administrative Agent and Borrower).

                  f. Subject to the  application  of the payment  provisions  of
Section 2.10(a), any prepayments of the Loans pursuant to this Section, Sections
2.13 or 2.14, or any other provision of any Loan Document shall be applied first
to any amounts payable with respect thereto pursuant to Section 2.15,  second to
the payment of accrued and unpaid interest on the principal  amount of all other
outstanding  Loans up to and including the date of prepayment,  and third to the
principal amount of all other outstanding Loans.  Subject to the requirements of
the  preceding   sentence,   Borrower  may  designate  the  application  of  any
prepayments, to be applied to principal on the Loans, to the Eurocurrency Loans,
Base Rate Loans and/or Alternate Rate Loans, as it may select,  provided that if
Borrower does not designate such application,  such prepayments shall be applied
(x) first to outstanding  Base Rate Loans,  (y) second to outstanding  Alternate
Rate Loans and (z) third to outstanding Eurocurrency Loans.

                  2.9.  Computation of Interest and Fees. Fees and other amounts
other  than  interest  calculated  on the  basis  of a rate per  annum  shall be
computed on the basis of a 360-day year for the actual days elapsed. Interest on
the Base Rate Loans and on the Alternate Rate Loans, in each case, calculated by
reference to the prime rate and interest on the Eurocurrency  Loans  denominated
in GBP shall be  computed  on the basis of a 365-day  year for the  actual  days
elapsed,  while interest on the Eurocurrency  Loans  denominated in U.S. Dollars
and interest on the Alternate Rate Loans and the Base Rate Loans,  in each case,
where  interest is not  calculated  by  reference  to the prime  rate,  shall be
computed on the basis of a 360-day year for the actual days elapsed.

                  2.10.Payments and Currency. (a) Except as contemplated by this
Agreement,  the borrowing by Borrower from the Lenders,  each payment (including
each prepayment) by Borrower on account of principal, interest and fees required
under  Sections  2.6(a)  and  (b),  and  any  reduction  of  the  amount  of the
Commitments  of the  Lenders  hereunder,  shall be made for the  account of each
Lender  according to its Pro Rata Share (except for fees payable  solely for the
account of the Agent or the  

                                      -45-
<PAGE>
Administrative Agent pursuant to Section 2.6(b)),  provided that payments to the
Lenders  of  interest   based  upon  the  Alternate   Rate  shall  be  allocated
appropriately to give effect to differences among the Lenders'  respective costs
of funds.  All  payments  (including  prepayments)  by  Borrower  on  account of
principal, interest, fees, costs, indemnities or other amounts payable hereunder
or under any of the Loan Documents shall be made to Administrative Agent for the
account  of the  applicable  Lenders  at the  account  of  Administrative  Agent
specified in Section 10.3(b) and in immediately  available funds in the currency
required by Section 2.10(b).  Each payment or prepayment hereunder and under the
Notes and the other Loan Documents shall be made without set-off or counterclaim
and free and  clear  of,  and  without  deduction  for,  any  present  or future
withholding  or other  taxes,  duties or  charges  of any  nature  imposed on or
attributable to such payments or prepayments by or on behalf of any Governmental
Authority,  except for any  Excluded  Taxes.  If any such taxes  (other than any
Excluded Taxes), duties or charges (including, without limitation, any tax, duty
or charge imposed by Sections 1, 2 and/or 39 of the Massachusetts  General Laws,
Chapter 63, as  currently  in effect or as amended  hereafter  or any  analogous
provisions  (or  provisions  having an analogous  effect) of the laws,  rules or
regulations  (or   interpretations   thereof)  of  Massachusetts  or  any  other
Governmental  Authority) are so levied or imposed on or are  attributable to any
such  payment or  prepayment,  Borrower  will make  additional  payments in such
amounts as may be necessary so that the net amount  received by a Lender,  after
withholding or deduction for or on account of all such taxes, duties or charges,
will be equal to the amount  provided for herein or in such  Lender's Note or in
any of the other  Loan  Documents.  Whenever  any taxes,  duties or charges  are
payable  by  Borrower  with  respect  to or  attributable  to  any  payments  or
prepayments  hereunder  or under any of the Notes or any  other  Loan  Document,
Borrower agrees to furnish promptly to  Administrative  Agent for the account of
the  applicable  Lender  official  receipts  or copies  thereof,  if  reasonably
available,  evidencing payment of any such taxes,  duties or charges so withheld
or deducted. If Borrower fails to pay any such taxes, duties or charges when due
to the appropriate taxing authority after receipt of notice that any such taxes,
duties or charges  are due,  or fails to remit to  Administrative  Agent for the
account of the applicable  Lender the customary  evidence of payment of any such
taxes,  duties or charges so withheld or deducted,  Borrower shall indemnify the
affected  Lender  for  any  incremental  taxes,  duties,  charges,  interest  or
penalties  that may  become  payable  by such  Lender  as a  result  of any such
failure.  During the continuance of any Default,  Administrative  Agent may, but
shall be under no obligation to, apply all payments  received by  Administrative
Agent from Borrower pursuant to any of the Loan Documents in the following order
of payment  regardless of the application  designated by Borrower:  first to any
interest owing under Section 2.4(b) or

                                      -46-
<PAGE>
under any of the Loan  Documents  other than interest owing on the Loans and the
Notes   referred  to  below,   second  to  any  fees  then   payable  to  Agent,
Administrative  Agent or the  Lenders,  third to any amounts  owing  pursuant to
Section 10.7,  fourth to any amounts owing  pursuant to Sections  2.13,  2.14 or
2.15,  fifth to any other sums (other than  principal on the Loans and the Notes
and interest  thereon  referred to below) owing under any of the Loan Documents,
sixth to any interest  owing on the Loans and Notes and seventh to the repayment
of the  principal  of the Loans and the Notes as  designated  by  Administrative
Agent;  provided that if such  application is other than in accordance  with any
express  designation by Borrower,  Administrative  Agent shall  promptly  notify
Borrower of such application.  Administrative Agent will distribute each payment
to the applicable Lenders promptly upon receipt thereof (and in any event on the
same Business Day as the date when  received,  if such payment is received at or
prior to 12:00 noon (New York time)). Each payment by Administrative  Agent to a
Lender  shall  be made  for the  account  of such  Lender's  Lending  Office  as
designated by such Lender to Administrative  Agent in writing from time to time.
Whenever any payment to be made hereunder or under any Loan Document, including,
without  limitation,  any principal of or interest on any Loan, shall become due
and payable,  or whenever the last day of any  Interest  Period would  otherwise
occur,  on a day which is not a Business Day, such payment shall be made and the
last day of such Interest Period shall occur on the next succeeding Business Day
and such extension of time shall in such case be included in computing  interest
on such payment; provided that if such extension would cause any such payment to
be made in the next succeeding  calendar month, or the last day of such Interest
Period to occur in the next  succeeding  calendar  month,  such payment shall be
made,  and the  last  day of such  Interest  Period  shall  occur,  on the  next
preceding Business Day.

                  (b) A repayment or  prepayment of a Loan or any part of a Loan
is  payable in the  currency  in which the Loan was  denominated  at the time at
which such Loan was made to Borrower  by Lenders.  Interest in respect of a Loan
is payable in the currency in which the principal portion of the respective Loan
in respect of which it is payable is denominated. Fees in respect of Commitments
or otherwise  hereunder  shall be payable in U.S.  Dollars.  Amounts  payable in
respect of costs, expenses and taxes and the like are payable in the currency in
which they are  incurred.  Any other amount  payable  under this  Agreement  is,
except as otherwise provided in this Agreement, payable in U.S. Dollars.

                  2.11.Use of  Proceeds.  The  proceeds  of the Loans  hereunder
shall be used by  Borrower  subject  to the  provisions  of  Section  5.4 hereof
(either directly or indirectly through intercompany advances of such proceeds to
its  Subsidiaries;  provided  that  no  Subsidiary  which  is  not a  Subsidiary
Guarantor may receive any such proceeds) for (a) the  acquisition of Properties,
(b) the acquisition or funding of Mortgage  Interests,  or (c) general corporate
purposes.

                  2.12.Increased Costs.

                  a. If any  Requirement of Law or other event or condition,  or
any  amendment,  modification  or  interpretation  thereof  (including,  without
limitation,  any request,  recommendation,  guideline or policy,  whether or not
having  the  force of law,  of or from any  central  bank or other  Governmental
Authority), in any such case, adopted,  effective, made or issued after the date
hereof (but in any event including, without limitation, Regulation D and Section
1, 2 and/or 39 of the  Massachusetts  General  Laws,  Chapter 63 as currently in
effect or as amended hereafter or any analogous provisions (or provisions having
an  analogous  effect) of the laws,  rules or  regulations  (or  interpretations
thereof) of Massachusetts or any other Governmental  Authority) by any authority
charged with the administration or interpretation thereof:

                             (i)  subjects  Agent,  Administrative  Agent or any
         Lender or any branch or  Affiliate  of Agent,  Administrative  Agent or
         such Lender to any tax (except Excluded Taxes), fee,  deduction,  duty,
         withholding,  levy,  impost or other charge or reduction of any nature,
         on or with  respect to, or which  Agent,  Administrative  Agent or such
         Lender in its sole discretion  deems applicable or attributable to this
         Agreement, any Note, any of the other Loan Documents, its Commitment or
         its pro rata share of the Loans,  or  interest,  fees or other  amounts
         attributable thereto or to any of the foregoing; or

                            (ii)  changes  the basis of  taxation of payments to
         any Lender or any branch or  Affiliate  of such Lender of  principal of
         and/or  interest  on such  share of the  Loans  and/or  other  fees and
         amounts  payable  hereunder or under any of the Loan  Documents or with
         respect  hereto or thereto  (including  in any event  imposition  of or
         change in any withholding taxes, but excluding any Excluded Taxes); or

                           (iii)  imposes  upon,  modifies,  requires,  makes or
         deems  applicable to any Lender,  or any of its branches or Affiliates,
         any  regular,  special,  supplementary  or  other  reserve  or  deposit
         requirement,  insurance  assessment or similar  requirement  against or
         affecting  any assets held by, or  liabilities  of, or deposits with or
         for the  account of,  such  Lender or such  branch or  Affiliate,  with
         respect to or which Agent or such Lender in its sole  discretion  deems
         applicable or  attributable  to this  Agreement,  any Note,  any of the
         other  Loan  Documents,  its  Commitment  or its pro rata  share of the
         Loans, or interest,  fees or other amounts  attributable  thereto or to
         any of the foregoing; or

                            (iv)  imposes,  modifies  or  deems  applicable  any
         condition or  requirement  upon or causes in any manner the addition of
         any supplement to, or increase of any kind to, the capital or cost base
         of  Agent,  Administrative  Agent  or any  Lender  or  such  branch  or
         Affiliate,  for extending or maintaining its Commitment or its pro rata
         share  of the  Loans  which  results  in an  increase  in  the  capital
         requirement  supporting  such  Commitment  or its pro rata share of the
         Loans, or imposes upon, modifies,  requires,  makes or deems applicable
         to Agent,  Administrative  Agent or such  Lender or any such  branch or
         Affiliate any capital  requirement,  increased  capital  requirement or
         similar  requirement,  with respect to or which  Agent,  Administrative
         Agent  or such  Lender  in its  sole  discretion  deems  applicable  or
         attributable  to  this  Agreement,  any  Note,  any of the  other  Loan
         Documents,  its  Commitment  or its pro  rata  share of the  Loans,  or
         interest,  fees or other amounts  attributable thereto or to any of the
         foregoing; or

                             (v) imposes upon Agent, Administrative Agent or any
         Lender or any branch or  Affiliate  of Agent,  Administrative  Agent or
         such  Lender any other  conditions  with  respect to, or  allocable  or
         attributable in good faith by Agent, Administrative Agent or the Lender
         to, this  Agreement,  any Note, any of the other Loan Documents or such
         share of the Loans or its Commitment hereunder or such interest, fees 
         or other amounts;

and the  result  of any of the  foregoing,  based  solely  upon the  good  faith
determination  and allocation by Agent,  Administrative  Agent or any Lender, as
the case may be, of costs, decreased benefits and/or reduced amount of payments,
is to  increase  the  cost or  decrease  the  benefit,  in any  way,  to  Agent,
Administrative  Agent  or such  Lender,  as the case may be,  or any  branch  or
Affiliate of Agent,  Administrative Agent or such Lender, as the case may be, of
funding or maintaining its Commitment or its share of the Loans hereunder, or to
reduce the amount of any payment (whether of principal,  interest, or otherwise)
received or receivable  by Agent,  Administrative  Agent or such Lender,  as the
case may be, or any branch or Affiliate of Agent,  Administrative  Agent or such
Lender,  as the case may be, or to require Agent,  Administrative  Agent or such
Lender, as the case may be, or any branch or Affiliate of Agent,  Administrative
Agent or such Lender,  as the case may be, to make any payment,  then and in any
such case:

                  1.       Agent,  Administrative  Agent or such Lender,  as the
                           case may be, shall promptly  notify  Borrower and the
                           other  Lenders in writing  of the  happening  of such
                           event;

                  2.       Agent,  Administrative  Agent or such Lender,  as the
                           case may be, shall  promptly  deliver to Borrower and

                                      -49-
<PAGE>
                           the other Lenders a certificate stating the change or
                           event  which has  occurred  or the reserve or capital
                           requirements  or other  conditions  which  have  been
                           imposed  on  Agent,   Administrative  Agent  or  such
                           Lender, as the case may be, or branch or Affiliate of
                           Agent,  Administrative  Agent or such Lender,  as the
                           case  may  be,   or  the   request,   recommendation,
                           guideline  or  policy  with  which  it has  complied,
                           together  with the date  thereof,  the amount of such
                           increased  cost,   decreased   benefit  or  reduction
                           payment; and

                  3.       Borrower  shall pay  Agent,  Administrative  Agent or
                           such Lender,  as the case may be,  promptly on demand
                           such an amount or amounts as:

                           (A) in the case of events referred to in clauses (i),
                  (ii),  (iii) and (v) and,  if  applicable,  clause (iv) above,
                  shall  be  sufficient  to  compensate  it or  such  branch  or
                  Affiliate for all such increased  costs and/or payments and/or
                  decreased benefits, and/or reduced amount of payment; and/or

                           (B) in the case of events  referred to in clause (iv)
                  above,  shall  be  an  amount  equal  to  the  reduction,   as
                  reasonably  determined by Agent,  Administrative Agent or such
                  Lender, as the case may be, in the after-tax rate of return on
                  Agent's,  Administrative  Agent's  or  such  Lender's  capital
                  resulting  from any  such  capital  or  increased  capital  or
                  similar requirement, all as certified by Agent, Administrative
                  Agent or such Lender or  Lenders,  as the case may be, in said
                  written  notice  to  Borrower.  Such  certification  shall  be
                  conclusive and binding on Borrower absent manifest error.

                  The certificate of Agent,  Administrative Agent or such Lender
as to the additional  amounts payable pursuant to this Section 2.12 delivered to
Borrower shall  constitute  prima facie evidence of the amount  thereof.  Agent,
Administrative  Agent  and each  Lender  agree  to use  reasonable  efforts,  as
determined by Agent, Administrative Agent or such Lender, as the case may be, to
avoid or minimize the payment by Borrower of any  additional  amounts under this
Section 2.12. The protection provided by this Section 2.12 shall be available to
Agent,   Administrative  Agent  and  each  Lender  regardless  of  any  possible
contention  of  invalidity  or   inapplicability  of  the  Requirement  of  Law,
interpretation,  recommendation,  guideline,  policy or event or condition which
has been imposed or has occurred.  In the event that after  Borrower  shall have
paid any  additional  amount  under this  Section 2.12 with respect to the Loans
Agent,  Administrative  Agent or such Lender shall have  successfully  contested
such Requirement of Law, 

                                      -50-
<PAGE>
interpretation, recommendation, guideline, policy or event or condition then, to
the extent that Agent, Administrative Agent or such Lender will be placed in the
same  position  it was in  prior  to the  incurrence  of the  increased  cost or
reduction in amount received or receivable (on an after-tax basis),  but without
giving effect to interest  which may have been earned on the  additional  amount
paid by  Borrower  (but with  interest to the extent  actually  earned by Agent,
Administrative  Agent or such  Lender,  as the case may be,  on such  amount  as
determined by Agent,  Administrative  Agent or such Lender, as the case may be),
Agent,  Administrative Agent or such Lender, as the case may be, shall refund to
Borrower such additional amount (with such interest, if any).

                  2.13. Change in Law Rendering  Eurocurrency Loans or Alternate
Rate Loans Unlawful; Failure to Give Notice of Continuation.

                  (a) Notwithstanding anything to the contrary herein contained,
in  the  event  that  any  Requirement  of Law or  any  change  in any  existing
Requirement  of  Law  or in  the  interpretation  thereof  by  any  Governmental
Authority charged with the administration  thereof, in any case adopted,  issued
or effective after the date hereof, (i) shall make it unlawful for any Lender to
fund any portion of the Eurocurrency  Loans or to give effect to its obligations
as  contemplated  hereby with respect to its making or maintaining  its pro rata
share of the  Eurocurrency  Loans, or (ii) shall make it unlawful for any Lender
to fund  any  portion  of the  Alternate  Rate  Loans or to give  effect  to its
obligations as  contemplated  hereby with respect to its Commitment or making or
maintaining  its pro rata share of the Alternate Rate Loans,  such Lender shall,
upon the happening of such event, notify Agent,  Administrative Agent, the other
Lenders and  Borrower  thereof in writing  stating the reason  therefor  and the
effective date of such event,  and (x) upon the  effectiveness of any such event
referred  to in clause  (i)  above,  the  obligation  of such  Lender to make or
maintain  its pro  rata  share  of the  Eurocurrency  Loans  to  Borrower  shall
forthwith  be  suspended  for the  duration of such  illegality  and during such
illegality  such Lender  shall,  upon payment of any amounts owing under Section
2.15 with  respect to such  conversion,  convert  its share of the  Eurocurrency
Loans to Alternate Rate Loans or (upon  effectiveness of any such event referred
to in clause (ii) and during the  continuance  of such event) Base Rate Loans in
the case of Loans denominated in U.S. Dollars or Alternate GBP Rate Loans in the
case of Loans  denominated  in GBP, and (y) upon the  effectiveness  of any such
event  referred  to in clause  (ii),  the  obligation  of such Lender to make or
maintain  its pro rata  share of the  Alternate  Rate  Loans to  Borrower  shall
forthwith  be  suspended  for the  duration of such  illegality  and during such
illegality  such Lender  shall,  upon payment of any amounts owing under Section
2.15 with respect to such  conversion,  convert its share of the Alternate

                                      -51-
<PAGE>
Rate Loans to Base Rate Loans in the case of Loans  denominated in U.S.  Dollars
or Alternate GBP Rate Loans in the case of Loans denominated in GBP. If and when
such  illegality with respect  thereto ceases to exist,  such  suspension  shall
cease and such affected  Lender shall  similarly  notify  Agent,  Administrative
Agent,  the other Lenders and Borrower and the Alternate  Rate Loan or Base Rate
Loan or Alternate GBP Rate Loan into which such share of the Eurocurrency  Loans
or Alternate Rate Loans (as applicable)  was converted  pursuant to this Section
2.13  shall be  reconverted  to a  Eurocurrency  Loan or  Alternate  Rate  Loan,
respectively, on the first day of the next succeeding Interest Period.

                  (b)  If   Borrower   fails   to   give  a  valid   Notice   of
Continuation/Conversion  in respect of any portion of a Eurocurrency  Loan which
is not repaid in  accordance  with the terms  hereof at the end of the  relevant
Interest   Period  in  respect   thereto,   such  portion   shall  be  converted
automatically  into Base  Rate  Loans in the case of Loans  denominated  in U.S.
Dollars or  Alternate  GBP Rate Loans in the case of Loans  denominated  in GBP;
provided   that   if   Borrower   subsequently   gives   a   valid   Notice   of
Continuation/Conversion in respect of such Base Rate Loans or Alternate GBP Rate
Loans, such Loans shall be converted into Eurocurrency  Loans in accordance with
the requirements for a continuation/conversion under Section 2.5.

                  (c) If  any  Loan  is  converted  to an  Alternate  Rate  Loan
pursuant  to  this  Section   2.13,   Borrower  and  Lenders,   acting   through
Administrative Agent, shall enter into negotiations in good faith with a view to
agreeing upon a substitute  basis for  determining the rate or rates of interest
from time to time  applicable  to such Loan,  which shall be  acceptable to each
Lender,  and the rate or rates so determined shall constitute the Alternate Rate
for that  Loan  from the date of such  conversion.  If,  however,  Borrower  and
Majority  Lenders fail to agree to such substitute basis within thirty (30) days
after such  conversion,  such Loan shall be deemed to have been converted to (i)
in the case of Loans denominated in U.S. Dollars,  a Base Rate Loan, and (ii) in
the case of Loans  denominated  in GBP, an Alternate GBP Rate Loan effective (in
the case of clauses (i) and (ii)) from the date of such conversion.

                  2.14. Eurocurrency Availability. (a) In the event, and on each
occasion,  that on the day two Business  Days prior to the  commencement  of any
Interest  Period for any  Eurocurrency  Loans,  Administrative  Agent shall have
determined  (which  determination  shall,  in the absence of manifest  error, be
conclusive and binding upon  Borrower) that U.S.  Dollar or GBP (as the case may
be) deposits in the amount of the  principal  amount of the  Eurocurrency  Loans
which is to have such Interest Period are not generally  available in the London
interbank market, or that the rate at which such U.S. Dollar or GBP (as the case
may be) deposits are being offered will not  accurately  reflect the cost to any
of the Lenders 

                                      -52-
<PAGE>
of making or funding such  principal  amount of such  Eurocurrency  Loans during
such Interest Period, or that reasonable means do not exist for ascertaining the
LIBO Rate,  Administrative Agent shall, as soon as practicable thereafter,  give
written  or  telephonic  notice  (which  telephonic  notice  shall  be  followed
immediately with a notice by facsimile telecopy) of such determination to Agent,
the Lenders and  Borrower  and (i) such  principal  amount of such  Eurocurrency
Loans  shall  automatically  be  converted,  as of the last day of the  Interest
Period during which such  determination is made, to Alternate Rate Loans subject
to the last sentence of this paragraph and (ii) any request by Borrower for such
Eurocurrency Loans pursuant to Section 2.3 hereof shall thereupon, and until the
circumstances  giving  rise to such  notice no  longer  exist  (as  notified  by
Administrative  Agent to Borrower and the Lenders),  be deemed a request for the
making of Alternate Rate Loans. If at any time  Administrative  Agent shall have
determined  (which  determination  shall,  in the absence of manifest  error, be
conclusive and binding upon Borrower)  that any  contingency  has occurred which
adversely  affects the London interbank market or that any Requirement of Law or
any change in any existing  Requirement of Law or in the interpretation  thereof
or other circumstance affecting the Lenders or the London interbank market makes
the funding of the Eurocurrency Loans impracticable, Administrative Agent shall,
as soon as  practicable  thereafter,  give written or  telephonic  notice (which
telephonic  notice  shall be  followed  immediately  with a notice by  facsimile
telecopy) of such  determination  to Agent, the Lenders and Borrower and (i) the
Eurocurrency Loans shall automatically be converted,  as of the last day of each
Interest  Period  during  which such  determination  is made and in each case in
respect of the  principal  amount of the  Eurocurrency  Loans having an Interest
Period  ending on such  date,  to  Alternate  Rate  Loans,  subject  to the last
sentence  of  this  paragraph,   and  (ii)  any  request  by  Borrower  for  the
Eurocurrency Loans pursuant to Section 2.3 hereof shall thereupon, and until the
circumstances  giving  rise to such  notice no  longer  exist  (as  notified  by
Administrative  Agent to Borrower,  Agent and the Lenders),  be deemed a request
for the making of Alternate Rate Loans.  If, in the  circumstances  specified in
this  paragraph or in Section  2.13,  Administrative  Agent  determines  that no
reasonable  alternate  source  of  funding  for the  Eurocurrency  Loans,  or no
reasonable   basis  for   determining   the  Alternate  Rate,  is  available  or
practicable,  Administrative  Agent shall  promptly so notify the other Lenders,
Agent and Borrower  thereof and any notice of borrowing  under Section 2.3 shall
be deemed  rescinded and each principal  amount of the  Eurocurrency  Loans,  if
outstanding,  having an Interest Period then current, together with all interest
thereon,  shall be due and payable by  Borrower on the last day of the  Interest
Period then applicable to it.

                  (c) If  any  Loan  is  converted  to an  Alternate  Rate  Loan
pursuant  to  this  Section   2.14,   Borrower  and  Lenders,   acting   through

                                      -53-
<PAGE>
Administrative Agent, shall enter into negotiations in good faith with a view to
agreeing upon a substitute  basis for  determining the rate or rates of interest
from time to time  applicable  to such Loan,  which shall be  acceptable to each
Lender,  and the rate or rates so determined shall constitute the Alternate Rate
for that  Loan  from the date of such  conversion.  If,  however,  Borrower  and
Majority  Lenders fail to agree to such substitute basis within thirty (30) days
after such  conversion,  such Loan shall be deemed to have been converted to (i)
in the case of Loans denominated in U.S. Dollars,  a Base Rate Loan, and (ii) in
the case of Loans denominated in GBP, an Alternate GBP Rate Loan,  effective (in
the case of clauses (i) and (ii)) from the date of such conversion.

                  2.15.  Indemnities.  Borrower  shall  indemnify each Lender on
demand for, from and against any actual loss (including, without limitation, any
loss of anticipated  profits) or expense  (including but not limited to any loss
or expense  sustained or incurred in  liquidating  or  employing or  redeploying
deposits  from third  parties  acquired  to effect or  maintain  any Loan or any
portion  thereof)  which such Lender or its branch or  Affiliate  may sustain or
incur as a  consequence  of (i) any  default  in payment  or  prepayment  of the
principal amount of any Loan or any portion thereof or interest accrued thereon,
as and when due and payable (at the due date thereof,  by irrevocable  notice of
payment or prepayment,  or otherwise),  (ii) the effect of the occurrence of any
Event of Default upon any Loan, (iii) the payment or prepayment of any principal
amount of any Loan or the conversion of any portion of any Eurocurrency  Loan to
Alternate Rate Loans or Base Rate Loans on any day other than the last day of an
Interest Period or the payment of any interest on such Loan, or portion thereof,
on a day other than an Interest Payment Date for the Loan or (iv) any failure of
Borrower  to accept or make a  borrowing  of the Loans or  continue or convert a
Loan after  delivery of a notice  requesting a Loan under Section 2.3 or, as the
case may be, a notice  requesting a continuation or conversion under Section 2.5
or any failure by Borrower to satisfy  any of the  conditions  precedent  to the
making of Loans  hereunder  after it has requested the borrowing  thereof (other
than any such  conditions  that are  waived in  accordance  with the  provisions
hereof).  The  determination  of each  Lender of any amount  payable  under this
Section 2.15 shall,  in the absence of manifest error, be conclusive and binding
upon Borrower.

                    SECTION 3.REPRESENTATIONS AND WARRANTIES

                  In order to induce the  Lenders  to enter into this  Agreement
and to make the Loans herein provided for, Borrower hereby covenants, represents
and warrants to Agent, Administrative Agent and each Lender that:

                  3.1. Financial  Condition.  The consolidated  balance sheet of
Borrower and its  Subsidiaries (if any) as at December 31, 1996 and December 31,
1997 and the related consolidated statements of income, stockholders' equity and
cash flows for the fiscal years ended on such dates,  certified by Ernst & Young
LLP, copies of which have  heretofore been furnished to Agent,  are complete and
correct  and  present  fairly  the  financial  condition  of  Borrower  and  its
Subsidiaries   (if  any)  on  a  consolidated   basis  as  at  such  dates,  and
stockholders'  equity and cash flows for the fiscal  years then ended.  All such
financial  statements,  including the related schedules and notes thereto,  have
been  prepared in  accordance  with GAAP  applied  consistently  throughout  the
periods involved (except as approved by such accountants or Responsible Officer,
as the case may be, and as disclosed  therein).  Borrower  and its  Subsidiaries
have no material Contingent Obligation,  contingent liabilities or liability for
taxes, long-term lease or unusual forward or long-term commitment,  which is not
reflected in the foregoing statements or in the notes thereto.

                  3.2. No Material  Adverse Effect.  Since December 31, 1997 (a)
there has been no Material  Adverse  Effect,  and no event has  occurred  and no
condition  exists which could  reasonably be expected to have a Material Adverse
Effect  and (b) no  dividends  or other  distributions  have been  declared  the
payment of which  could  result in a Default  or Event of  Default  nor have any
Common  Shares,  Preferred  Shares or other equity  securities  of Borrower been
redeemed,  retired, purchased or otherwise acquired for value by Borrower or any
of its Subsidiaries.

                  3.3. Existence;  Compliance with Law. Borrower and each of its
Subsidiaries  (a) is, in the case of Borrower,  a real estate  investment  trust
duly  organized,  validly  existing and in good  standing  under the laws of the
State of Maryland and, in the case of each such Subsidiary, a corporation,  real
estate investment trust or limited liability  company,  as the case may be, duly
organized,  validly  and  existing  and in good  standing  under the laws of its
respective  jurisdiction of incorporation,  (b) has full power and authority and
the legal right to own its  property,  to lease (as lessee) the property that it
leases as lessee,  to lease (as lessor) or sublease  the property it owns and/or
leases (as lessee) and to conduct the business in which it is currently engaged,
(c)  is  duly  qualified  and  is in  good  standing  under  the  laws  of  each
jurisdiction  where its  ownership  or lease of  property  or the conduct of its
business require such qualification, except to the extent that the failure to be
so  qualified  or in good  standing  is not  reasonably  likely to have,  in the
aggregate,  a Material Adverse Effect, and has all material licenses required by
each such  jurisdiction,  and (d) is in compliance with all  Requirements of Law
except to the extent  that the  failure to comply  therewith  is not  reasonably
likely to have, in the aggregate, a Material Adverse Effect.

                  3.4. Tenant, Advisor, Credit Support Obligors; Compliance with
Law.

                  a.  To  the  best  knowledge  of  Borrower,  each  Tenant  and
Mortgagor (i) has full power and authority and the legal right to own, lease (or
sublease) and operate (as  applicable) the Properties it operates and to conduct
the business in which it is currently engaged with respect to any Property, (ii)
is duly  qualified  or licensed and is in good  standing  under the laws of each
jurisdiction  where its  ownership,  lease (or  sublease)  or  operation  of any
Property  requires  such  qualification,  and  (iii) is in  compliance  with all
Requirements  of Law applicable to the Properties  operated by it, or applicable
to the  operation  thereof  except  to the  extent  that the  failure  to comply
therewith is not reasonably likely to have, in the aggregate, a Material Adverse
Effect.

                  b. To the best knowledge of Borrower, the Advisor (i) has full
power and  authority  and legal  right to conduct  the  business  in which it is
presently engaged and to perform its obligations  under the Advisory  Agreement,
(ii) is duly  qualified  or licensed and is in good  standing  under the laws of
each jurisdiction where the conduct of its business requires such qualification,
and (iii) is in  compliance  with all  Requirements  of Law except to the extent
that the failure to comply  therewith is not  reasonably  likely to have, in the
aggregate, a Material Adverse Effect.

                  c. To the best  knowledge  of  Borrower,  the  Credit  Support
Obligors  (i) have full  power and  authority  and legal  right to  conduct  the
business in which they are presently  engaged and to perform  their  obligations
under the Credit Support  Agreements to which they are parties,  and (ii) are in
compliance with all Requirements of Law, except,  in the case of clauses (i) and
(ii),  to the extent  that the  failure to comply  therewith  is not  reasonably
likely to have, in the aggregate, a Material Adverse Effect.

                  3.5. Power; Authorization;  Enforceable Obligations.  Borrower
and each of its  Subsidiaries has the power and authority and the legal right to
make, deliver and perform each of the Loan Documents to which it is a party and,
in the case of  Borrower,  to  borrow  hereunder;  and  Borrower  has  taken all
necessary  action  to  authorize  the  borrowings  hereunder,  on the  terms and
conditions of the Loan Documents,  and Borrower and each of its Subsidiaries has
taken all necessary action to authorize the execution,  delivery and performance
of  each  of  the  Loan  Documents  to  which  it  is a  party.  No  consent  or
authorization of, filing with, or other act by or in respect of any Governmental
Authority is required in connection  with the  borrowings  hereunder or with the
execution,  delivery,

                                      -56-
<PAGE>
performance,  validity or enforceability  of the Loan Documents.  This Agreement
has been,  and each other Loan  Document will be, duly executed and delivered on
behalf of Borrower  and each of its  Subsidiaries  which is a party  thereto and
this  Agreement  constitutes,  and each other Loan  Document  when  executed and
delivered will constitute, a legal, valid and binding obligation of Borrower and
each of its Subsidiaries which is a party thereto  enforceable  against Borrower
and each of its  Subsidiaries  which is a party thereto in  accordance  with its
terms,  except  as  enforceability  may be  limited  by  applicable  bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting the enforcement
of creditors' rights generally.

                  3.6. No Legal Bar. The execution,  delivery and performance of
this Agreement and the other Loan  Documents,  the borrowings  hereunder and the
use of the  proceeds  thereof,  will not violate any  Requirement  of Law or any
Contractual  Obligation  of  Borrower or any of its  Subsidiaries,  and will not
result in, or require,  the creation or  imposition  of any Lien on any of their
respective  properties  or  revenues  pursuant  to  any  Requirement  of  Law or
Contractual Obligation.

                  3.7. No Material Litigation.  No litigation,  investigation or
proceeding of or before any arbitrator or Governmental  Authority is pending or,
to the best knowledge and belief of Borrower,  threatened by or against Borrower
or any of its  Subsidiaries  or against any of their  respective  properties  or
revenues or, to the best knowledge and belief of Borrower,  by or against any of
the Tenants and  Mortgagors or against any of their  respective  properties  (a)
with respect to this  Agreement  or the other Loan  Documents,  the Leases,  the
Mortgage Interest Agreements,  or any of the transactions contemplated hereby or
thereby,  or (b) relating to the  Properties,  the  Mortgaged  Properties or the
ownership  or the  operation  thereof  or the  conduct  of  business  thereon as
presently  conducted,  which, in the case of (a) or (b), is reasonably likely to
have, in the aggregate, a Material Adverse Effect.

                  3.8. No Default.  Neither Borrower nor any of its Subsidiaries
is in default under or with respect to any Contractual Obligation in any respect
which could have a Material  Adverse Effect.  No Default or Event of Default has
occurred and is continuing.

                  3.9. Ownership of Mortgage Interests and Property; Liens.

                  a. In the case of a Mortgage Interest,  Borrower or one of its
Subsidiaries has good record, marketable and indefeasible title to such Mortgage
Interest. In the case of a Property which is a Fee Interest,  Borrower or one of
its  Subsidiaries  has good  record,  marketable  and  indefeasible  fee  simple
absolute  title  

                                      -57-
<PAGE>
to such Fee Interest.  In the case of a Property which is a Leasehold  Interest,
Borrower or one of its Subsidiaries has good record and marketable title to such
Leasehold  Interest.  In the case of a Mortgage Interest in respect of which all
or any  part  of  the  Mortgaged  Property  is a fee  interest  in  land  and/or
buildings, structures,  improvements and fixtures, the Mortgagor with respect to
such Mortgaged Property has good record,  marketable and indefeasible fee simple
absolute title to such Mortgaged Property. In the case of a Mortgage Interest in
respect  of  which  all or any part of the  Mortgaged  Property  is a  leasehold
estate,  the Mortgagor with respect to such  Mortgaged  Property has good record
and marketable title to such leasehold estate. In each of the cases described in
this  Section  3.9,  such  title  shall be free and clear of all Liens and other
matters  affecting title except for such other matters not reasonably  likely to
have, in the aggregate, a Material Adverse Effect.

                  b. The buildings,  structures,  and other improvements located
on each Property are in good operating  condition and repair  (ordinary wear and
tear which are not such as to materially and adversely  affect the operations of
the business conducted thereon,  excepted),  free of any material  structural or
engineering  defects  known to Borrower or any of its  Subsidiaries  on the date
hereof and are suitable for their present uses, subject to such exceptions which
are not reasonably likely to have, in the aggregate, a Material Adverse Effect.

                  c. All water,  sewer,  gas,  electricity,  telephone and other
utilities serving each Property are supplied directly to such Property by public
utilities and enter such Property  through  adjoining public streets or, if they
pass through  adjoining  private  land,  do so in  accordance  with valid public
easements which inure to the benefit of Borrower or one of its  Subsidiaries (in
the case of a Property in which Borrower or such  Subsidiary has a Fee Interest)
or a mortgagor's  or  beneficiary's  benefit (in the case of a Property in which
Borrower or such Subsidiary is a mortgagor or beneficiary,  as applicable,  of a
loan  secured  in whole  or in part by a Lien on a  Property),  subject  to such
exceptions which are not reasonably likely to have, in the aggregate, a Material
Adverse Effect. All of such utilities are presently  installed and operating and
are in good  and  safe  condition,  subject  to such  exceptions  which  are not
reasonably  likely to have, in the aggregate,  a Material  Adverse  Effect.  All
material  assessments  for public  improvements  that have been made against the
Properties  have  been  paid or  provided  for,  except  that in the case of any
assessments  that are payable in  installments,  all  installments due as of the
date hereof have been paid or provided for, subject to such exceptions which are
not reasonably likely to have, in the aggregate, a Material Adverse Effect.

                  d. None of Borrower or any of its  Subsidiaries or to the best
knowledge  and belief of  Borrower,  the Tenants and  Mortgagors,  has  received
notice of any pending,  threatened or  contemplated  condemnation  proceeding or
similar taking affecting 

                                      -58-
<PAGE>
the Properties,  or any portion thereof, or any sale or other disposition of the
Properties or any portion thereof in lieu of condemnation or similar taking,  in
each case,  subject to such exceptions which are not reasonably  likely to have,
in the aggregate, a Material Adverse Effect.

                  e. All Real Property Permits from all Governmental Authorities
having  jurisdiction over the Properties or any portion thereof,  the absence of
which could materially impair the use of any Property for the purposes for which
it is  currently  used,  and from all  insurance  companies  and fire rating and
similar boards and organizations required to have been issued to Borrower or any
of its Subsidiaries or any Tenants and Mortgagors of such Property,  as the case
may be, to enable such Property or any portion  thereof to be lawfully  occupied
and used as currently so occupied or used have been issued and are in full force
and effect,  subject to such exceptions which are not reasonably likely to have,
in the aggregate,  a Material  Adverse Effect.  Neither  Borrower nor any of its
Subsidiaries  has  received or been  informed by a third  party,  including  the
Tenants and  Mortgagors  of the  Properties,  of the receipt by it of any notice
from any Governmental  Authority having  jurisdiction over the Properties or any
portion thereof or from any insurance company or fire rating or similar board or
organization threatening a suspension, revocation,  modification or cancellation
of any Real Property Permit, subject to such exceptions which are not reasonably
likely to have, in the aggregate, a Material Adverse Effect. Each of the Leases,
Mortgage  Interest   Agreements  and  Credit  Support  Agreements   relating  to
Properties and Mortgage Interests  (including  Properties which are not Eligible
Properties and Mortgage  Interests which are not Eligible  Mortgages) is in full
force and effect and is a legally  valid and binding  obligation  of Borrower or
its Subsidiaries and the other parties thereto, subject to such exceptions which
are not reasonably likely to have, in the aggregate,  a Material Adverse Effect.
Neither Borrower nor any of its Subsidiaries has mortgaged, pledged or otherwise
encumbered  any of the Leases or Mortgage  Interest  Agreements  or its right to
obtain  rental,  interest  or other  payments  thereunder  except  for the Liens
permitted  by Section 6.9.  Neither  Borrower  nor any of its  Subsidiaries  has
collected  any rents  becoming  due under any Lease more than 30 days in advance
(except (i) an amount equal to one month's  instalment  of rent under a Lease or
(ii) in the case of a lease  acquired  from Host  Marriott  Corporation  and its
Affiliates  pursuant to the transaction (or one on substantially  similar terms)
described  in the Form S-3  Registration  Statement  of Borrower  filed with the
Commission  on April 29,  1994,  an amount  equal to no more than three  months'
instalment  of rent  under  such  lease).  All rent and other  sums and  charges
payable by any Tenant  under each Lease to which it is a party are  current,  no
notice of  default  or  termination  under  any such  Lease is  outstanding,  no
termination event or condition or uncured default on the part of a Tenant exists
under any Lease, and no event of default has occurred which,  with the giving of
notice

                                      -59-
<PAGE>
or the lapse of time or both,  would  constitute  such a default or  termination
event  or  condition  or  uncured  default  on  the  part  of  Borrower  or  its
Subsidiaries  or the  Tenants (as the case may be),  subject to such  exceptions
which are not reasonably  likely to have, in the aggregate,  a Material  Adverse
Effect.  Except as set  forth on  Schedule  6, all  payments  required  from any
Mortgagor  under  any  Mortgage  Interest  Agreement  to which it is a party are
current,  no notice of default or acceleration  under any such Mortgage Interest
Agreement is outstanding, no default or condition or uncured default on the part
of the Mortgagor exists under any Mortgage Interest  Agreement,  and no event of
default has  occurred  which,  with the giving of notice or the lapse of time or
both,  would  constitute  such a default or  termination  event or  condition or
uncured default on the part of the Mortgagor,  subject to such exceptions  which
are not reasonably likely to have, in the aggregate,  a Material Adverse Effect.
All payments  required from any Credit Support  Obligor in respect of any Credit
Support  Agreement  for the Lease of a Property or for a Mortgage  Interest  are
current,  no notice of default or  acceleration  under any such  Credit  Support
Agreement is outstanding,  and no default or condition or uncured default on the
part of such  Credit  Support  Obligor  exists  under  any such  Credit  Support
Agreement,  subject to such exceptions which are not reasonably  likely to have,
in the aggregate,  a Material Adverse Effect. As to all of the Leases,  Borrower
and each of its  Subsidiaries  has performed  all of its repair and  maintenance
obligations  (if any) and, to the best  knowledge  and belief of Borrower,  each
Tenant and  Mortgagor  under each Lease and  Mortgage to which it is a party has
performed  all of its  repair  and  maintenance  obligations,  subject  to  such
exceptions which are not reasonably likely to have, in the aggregate, a Material
Adverse Effect.

                  f. Borrower and each of its  Subsidiaries  has good record and
marketable  title in fee simple to or valid  mortgage  interests in all its real
property,  other  than the  Properties  and  Mortgaged  Properties,  as to which
Borrower has made the representation set forth in subsection (a) of this Section
3.9, and good title to all its other  property  other than the  Properties,  and
none of such  property is subject to any Lien for borrowed  money as of the date
hereof, except for Liens permitted by Section 6.9.

                  3.10. No Burdensome Restrictions. No Contractual Obligation of
Borrower or any of its Subsidiaries or, to Borrower's best knowledge and belief,
of any of the Tenants and  Mortgagors  and no Requirement of Law currently has a
Material Adverse Effect, or insofar as Borrower may reasonably  foresee may have
a Material Adverse Effect.

                  3.11.  Taxes.  Borrower and each of its Subsidiaries has filed
or caused to be filed all tax returns which to the best  knowledge and belief of
Borrower are  required to be filed,  and has paid or caused to be paid all taxes
shown to be due and payable on 

                                      -60-
<PAGE>

said  returns or on any  assessments  made against it or any of its property and
all other taxes,  fees or other charges  imposed on it or any of its property by
any Governmental  Authority (other than those the amount or validity of which is
currently  being  contested in good faith by  appropriate  proceedings  and with
respect to which  reserves  in  conformity  with GAAP have been  provided on the
books of Borrower or such Subsidiary);  and no tax Liens have been filed and, to
the knowledge of Borrower, no claims are being asserted with respect to any such
taxes,  fees or other charges and there are no matters under discussion with any
Governmental  Authority  that,  in any such  case,  could  result in a  material
additional  liability for taxes and which would reasonably be expected to have a
Material Adverse Effect.

                  3.12.  Federal  Regulations.  Neither  Borrower nor any of its
Subsidiaries  is  engaged,  nor  will it  engage,  principally  or as one of its
important  activities,  in the business of  extending  credit for the purpose of
"purchasing" or "carrying" any "margin stock" within the respective  meanings of
each of the quoted  terms under  Regulation  U of the Board of  Governors of the
Federal Reserve System as now and from time to time hereafter in effect. No part
of the  proceeds  of the  Loans  hereunder  will be  used  for  "purchasing"  or
"carrying"  "margin stock" as so defined or for any purpose which  violates,  or
which would be  inconsistent  with,  the  provisions of the  Regulations of such
Board of  Governors.  If requested by Agent,  Borrower will furnish to Agent and
each Lender a statement in conformity  with the  requirements of Federal Reserve
Form U-1 referred to in said Regulation U to the foregoing effect.

                  3.13. Employees.  Neither Borrower nor any of its Subsidiaries
has any employees and none of them has ever engaged any employees.

                  3.14.  ERISA. No ERISA Affiliate has been, since July 1, 1974,
an  "employer",  as defined in Section 3(5) of ERISA,  in respect of any Plan or
making contributions to any Multiemployer Plan.

                  3.15. Status as REIT. Borrower is organized in conformity with
the requirements for  qualification as a real estate  investment trust under the
Code.  Borrower's  failure to elect to be treated  as a real  estate  investment
trust under the Code for its fiscal year ended December 31, 1986 has not had and
will  not  have  any  Material  Adverse  Effect.  Borrower  has  met  all of the
requirements for  qualification as a real estate investment trust under the Code
for its fiscal  years  ended  December  31,  1993,  1994,  1995,  1996 and 1997.
Borrower  is in a position  to qualify  for its  current  fiscal  year as a real
estate  investment  trust under the Code and its  proposed  methods of operation
will enable it to so qualify.

                                      -61-
<PAGE>

                  3.16. Restrictions on Incurring Indebtedness. Neither Borrower
nor  any  of  its  Subsidiaries  is (a) an  "investment  company"  or a  company
"controlled"  by an "investment  company,"  within the meaning of the Investment
Company Act of 1940,  as amended,  or (b) a "holding  company" as defined in, or
otherwise subject to, regulation under the Public Utility Holding Company Act of
1935.  Neither  Borrower nor any of its  Subsidiaries  is subject to  regulation
under any federal or state  statute or  regulation  which  limits its ability to
incur the indebtedness or give the guaranties described in this Agreement.

                  3.17. Subsidiaries.  Set forth on Schedule 4 annexed hereto is
a complete and accurate list of all of Borrower's Subsidiaries showing as of the
date hereof (as to each Subsidiary) the jurisdiction of its  incorporation,  the
number of shares of each  class of  capital  stock  authorized,  and the  number
outstanding,  and the  percentage  of each  class  of  capital  stock  owned  by
Borrower,  all of which capital stock is owned free and clear of all Liens;  all
of the issued and outstanding  shares of capital stock of such Subsidiaries have
been duly authorized and validly issued and are fully paid and non-assessable.

                  3.18. Compliance with Environmental Laws. Borrower and each of
its  Subsidiaries  and, to the best knowledge of Borrower,  each Tenant and each
Mortgagor of the Properties is in compliance with all applicable statutes, laws,
rules,  regulations  and  orders of all  Governmental  Authorities  relating  to
environmental  protection,  pollution  control and Hazardous  Materials and with
respect to the conduct of its  business  and the  ownership  of its  properties,
except for such  noncompliance  which would not result in  imposition  of Liens,
fines,  penalties,  injunctive relief or other civil or criminal liabilities and
which, in the aggregate, could not have a Material Adverse Effect.

                  3.19. Pollution;  Hazardous Materials.  In connection with the
acquisition  and  ownership  of its  interests  in the  Properties  and Mortgage
Interests,  Borrower and each of its  Subsidiaries has made and will continue to
make such inquiries, and has and will continue to cause such testing, surveying,
inspection  or other  action,  with respect to each  Property as is necessary or
desirable in connection  with Hazardous  Materials which might be present in the
air,  soil,  surface  water or  groundwater  at such  Property.  Except for such
exceptions which are not reasonably likely to have, in the aggregate, a Material
Adverse Effect,  there are not, and, to the knowledge of Borrower after diligent
inquiry, were not previously,  any Hazardous Materials present in the air, soil,
surface water or groundwater at any Property and no Hazardous  Materials (except
Hazardous  Materials  maintained in accordance with all  Requirements of Law and
necessary  for the  business  operations  of any such  Property as a health care
facility,  including,  without  

                                      -62-
<PAGE>
limitation,  petroleum used for heating oil and certain medications) are used in
the operation of any  Property.  Borrower is not aware of any claim or notice of
violation,  alleged violation,  noncompliance,  liability or potential liability
relating  to any  Property  nor any  judicial  proceedings  or  governmental  or
administrative actions pending or, to the knowledge of Borrower,  threatened, to
which Borrower or any of its  Subsidiaries  would be named a party in connection
with any Property which, if adversely determined,  would be reasonably likely to
result in a Material Adverse Effect.

                  3.20.  Securities  Laws. None of the Common Shares,  Preferred
Shares or other  equity  securities  of Borrower has been issued in violation of
the Securities Act of 1933, as amended, or the securities or "blue sky" or other
applicable laws or regulations of any applicable jurisdiction.

                  3.21. Declaration of Trust, By-Laws,  Advisory Agreement, etc.
The copies of the  Declaration of Trust and by-laws of Borrower and the Advisory
Agreement  which have been  furnished  to Agent are true,  correct and  complete
copies thereof as in effect on the date of this Agreement.

                  3.22.  Disclosures.  The financial  statements  referred to in
Section 3.1 do not, nor does this Agreement,  the other Loan  Documents,  or any
other written  statement  furnished by or on behalf of Borrower to any Lender in
connection with the  transactions  contemplated  hereby or thereby,  contain any
untrue  statement of a material fact or omit a material  fact  necessary to make
the statement contained therein or herein not misleading.

                  3.23. Certification.  Subject to such exceptions which, in the
aggregate,  are not reasonably  likely to have a Material Adverse Effect, to the
best  knowledge of Borrower  after  reasonable  investigation,  each Tenant with
respect to each of the  Properties  that it operates,  and each  Mortgagor  with

eligible for  participation  in Medicare or Medicaid or such other program,  and

agent with the authority of Borrower has offered any  securities  similar to the
Notes,  nor  solicited any offer to buy any such  securities,  in a manner which
would  render  the  offering,  sale or  issuance  of the  Notes  subject  to the
registration requirements of the Securities Act of 1933, as amended.

                  3.25.  Addressing  the Year 2000 Issue.  Borrower has reviewed
its operations and those of its Subsidiaries and major commercial counterparties

will,  in  the  receipt,  transmission,   processing,   manipulation,   storage,
retrieval,  retransmission or other utilization of data, be vulnerable to a Year
2000  Issue.  Based on such  review,  Borrower  has no reason to believe  that a
Material  Adverse  Effect  will occur with  respect to its or its  Subsidiaries'
businesses or operations resulting from a Year 2000 Issue.

                                      -72-
<PAGE>

Properties and/or Mortgaged  Properties covered by Eligible Mortgages.  Any such
Appraisal  shall be at Borrower's cost if (i) Agent shall have obtained a letter
from an expert  appraiser or evaluator of real  property to the effect that,  or
Agent shall otherwise in good faith have determined that, facts or circumstances
exist, or changes in market conditions have occurred, as a result of which there
exists a reasonable  possibility that Appraisals of the Eligible  Properties and
Mortgaged Properties covered by Eligible Mortgages, might result in an aggregate
valuation  thereof  reflecting a material loss of value as compared to the value
thereof indicated in the certificate of a Responsible Officer delivered to Agent
pursuant to Section 4.1(j) or 5.2(b) or (ii) an Event of Default has occurred.

                  b.  In  addition  to the  Appraisals  referred  to in  Section
5.9(a), from time to time during the term of this Agreement,  if so requested by
Agent, in its sole discretion,  Borrower shall furnish to Administrative  Agent,
with sufficient  copies for each Lender, a certificate of a Responsible  Officer
certifying  as to the  value of one or more of the  Eligible  Properties  and/or
Mortgaged Properties covered by Eligible Mortgages.

                  5.10. Meetings.  Within one hundred days after the end of each
fiscal year of  Borrower,  one or more  Responsible  Officers of Borrower  shall
attend an annual  informational  meeting  with the  Lenders,  for the purpose of
answering reasonable questions of any Lender, Agent and/or  Administrative Agent
relating to the Properties  and/or the Loan Documents,  to be held at Borrower's
cost and at such  time  and  place to be  determined  by Agent as is  reasonably
requested  by  Agent;  provided  that  each  Lender  shall  bear  the  costs  of
transportation and accommodation for any of its  representatives  attending such
meeting.

                  5.11. REIT Requirements.  Operate its business at all times so
as to satisfy  or be deemed to have  satisfied  all  requirements  necessary  to
qualify as a real estate  investment  trust under Section 856 through 860 of the
Code.  Borrower  will  maintain  adequate  records  so as  to  comply  with  all
record-keeping  requirements relating to the qualification of Borrower as a real
estate  investment  trust as required by the Code and applicable  regulations of
the Department of the Treasury promulgated  thereunder and will properly prepare
and timely  file with the  Internal  Revenue  Service  all  returns  and reports
required  thereby.  Borrower will request from its  shareholders all shareholder
information required by the Code and applicable regulations of the Department of
Treasury promulgated thereunder.

                  5.12.  Indemnification.  Borrower agrees to indemnify,  defend
(with  counsel  selected by Agent) and hold Agent,  Administrative  Agent,  each
Co-Agent,  Lenders and the  directors,  officers,  shareholders,  employees  and

party claims for personal injury or real or personal property damage),  actions,
administrative  proceedings,  judgments,  damages, punitive damages,  penalties,
fines,  costs,  expenses  disbursements,  liabilities  (including  sums  paid in
settlements of claims),  obligations,  interest or losses,  including attorneys'
fees,  consultant  fees and  expert  fees,  that  arise at any time  (including,
without  limitation,  at any time after the  payment of the Notes)  directly  or
indirectly from or in connection with the presence,  suspected presence, release
or suspected release of any Hazardous  Material in the air, soil,  surface water
or groundwater at or from the real property or any portion  thereof with respect
to a  Property,  or any other  real  property  in which  Borrower  or any of its
Subsidiaries  has any interest  (all of the  foregoing  real  property  shall be
referred  to  collectively  as  the  "Real  Property").   Without  limiting  the
generality of the foregoing,  the indemnification provided by this Section shall
specifically  cover (i) costs,  including  capital,  operating  and  maintenance
costs,  incurred in  connection  with any  investigation  or  monitoring of site
conditions or any clean-up,  remedial,  removal or restoration  work required or
performed  by any  federal,  state or local  governmental  agency  or  political
subdivision or performed by any non-governmental Person, including any Tenant or

groundwater at or from the Real Property;  and (ii) costs incurred in connection
with (A) Hazardous Material present or suspected to be present in the air, soil,

this  Agreement,  or (C)  Hazardous  Material  present at the Real Property as a
result  of any  release,  discharge,  disposal,  dumping,  spilling  or  leaking
(accidental or otherwise)  onto or from the Property before or after the date of
this Agreement by any Person.

                  5.13.  Changes in GAAP.  Borrower and the Lenders hereby agree
that in the event of a change in GAAP which would cause the financial  covenants
set forth  herein to provide  less  protection  to the  Lenders  than  presently
provided for hereunder,  such financial covenants shall be reset, in good faith,
by the Majority Lenders to maintain the protection to the Lenders  equivalent to
that in place  prior to such change and  Borrower  agrees to execute one or more
amendments to this Agreement to effect such reset.

                  5.14.  Restrictions on Negative Pledges. If Borrower or any of
its  Subsidiaries  shall agree to any "negative  pledge" or like  agreement more
restrictive (or otherwise more generous to its  

                                      -74-
<PAGE>
beneficiaries)  in its scope than Section 6.9, then,  without any further action
being required,  the provisions of such agreement relating to the prohibition on
Liens shall be deemed incorporated by reference (with appropriate  modifications
as may be necessary)  into this  Agreement for the benefit of Lenders;  provided
that  the  foregoing  covenant  shall  not  apply to the  prohibitions  on Liens
contained in the loan documents  relating to the Government  Properties  Assumed
Indebtedness as of the date of the merger of Government Properties with and into
Hub and not created in contemplation of such merger.

                  5.15. Currency Arrangements.

                  (a) Borrower shall at all times maintain  Currency  Agreements
in form and substance  satisfactory to Agent which will protect Borrower and its
Subsidiaries  against  fluctuations in foreign  currency values against the U.S.
Dollar.

                  (b)  Borrower  shall  only enter into  Hedging  Agreements  or
Currency Agreements as are (in Borrower's reasonable judgment) necessary for the
hedging or other  protection to exposure of Borrower and its  Subsidiaries,  and
not those which are of a purely speculative nature.

                  5.16. Year 2000.  Borrower has taken and shall take all action
necessary to assure that its data processing and information  technology systems
are capable of effectively processing data and information,  including dates, on
and after January 1, 2000,  and shall not cease to perform,  or provide or cause
any software  and/or  system which is material to the  operations of Borrower or
any interface  therewith to provide invalid or incorrect  results as a result of
date  functionality  and/or data, or otherwise  experience  any  degradation  of
performance  or   functionality   and/or  data,  or  otherwise   experience  any
degradation  of  performance  or  functionality  arising  from,  relating  to or
including  date  functionality   and/or  data  which  represents  or  references
different  centuries  or more than one  century  or leap years and that all such
systems shall  effectively  and accurately  manage and  manipulate  data derived
from,  involving  or  relating  in any way to  dates  including  single  century
formulas  and  multi-century  or leap  year  formulas,  and  will  not  cause an
abnormally  ending scenario within such systems or in any software and/or system
with which such  systems  interface,  or  generate  incorrect  values or invalid
results involving such dates.

shall occur or exist with respect to a Plan or a Multiemployer Plan; and in each
case in clauses (i) through (iv) above,  such event or condition,  together with
all other such events or conditions,  if any,  could subject  Borrower or any of
its  Subsidiaries  to any tax,  penalty or other  liabilities  in the  aggregate
material in relation to the business, operations, property or financial or other
condition of Borrower and its Subsidiaries, taken as a whole; or

                  i. Certain  Judgments.  One or more judgments or decrees shall
be  entered  against  Borrower  or  any  of its  Subsidiaries  involving  in the
aggregate  a  liability  (not paid or fully  covered  by  insurance,  except for
reasonable and customary deductibles) of $10,000,000 or more, and either (x) all
such  judgments or decrees  shall not have been vacated,  discharged,  stayed or
bonded  pending  appeal or (y) funds in the amount of the  liability  thereunder
(not paid or fully covered by insurance) shall not have been deposited in escrow
with Agent upon terms and conditions  satisfactory  to Agent, in each case under
clause (x) or (y), within 60 days from the entry thereof; or

                  j. Certain Ownership of Borrower.  Barry M. Portnoy and Gerard
M.  Martin (or any  Person in  respect of which  either or both of them own more
than 50% of the  securities  having  ordinary  voting  power for the election of
directors) shall cease at any time to hold  beneficially  and of record,  in the
aggregate,  at least 750,000 shares of the issued and outstanding  Common Shares
and  each  other  class of  equity  securities  of  Borrower  (adjusted  for any
division,  reclassification  or stock  dividend in respect of Common  Shares) or
such lesser amount as shall be approved by Agent; or

                  k. Change of Control of Advisor. At any time, neither Barry M.
Portnoy nor Gerard M. Martin nor both  acting  together  shall have the power to
direct the management and policies of the Advisor; or

                  l. Investment  Grade Tenants and Mortgagors.  More than 50% of
the aggregate  Allowed Value of the Properties and Mortgage  Interests  shall be
attributable  to Properties and Mortgage  Interests  having the same  Investment
Grade Person (or any of that Person's Affiliates; provided that for the purposes
of this  Section  7.1(l),  so long as  there  is no  material  change  in  their
practices  and  procedures  in  place  at the  Effective  Date  to  provide  for
arm's-length dealings, Marriott International,  Inc. and its Affiliates and Host
Marriott  Corporation  and its  Affiliates  will not be treated as Affiliates of
each other) as Mortgagor or Tenant thereof; or

                                      -81-
<PAGE>
                  m.  Tenants and  Mortgagors  Generally.  Except in the case of
Mortgagors or Tenants which are Investment  Grade Persons,  more than 40% of the
aggregate  Allowed  Value of the  Properties  and  Mortgage  Interests  shall be
attributable to Properties and Mortgage Interests having the same non-Investment
Grade Person (or any of that Person's Affiliates; provided that for the purposes
of this Section 7.1(m) so long as there is no material change in their practices
and  procedures  in place at the  Effective  Date to  provide  for  arm's-length
dealings,  Marriott  International,  Inc. and its  Affiliates  and Host Marriott
Corporation  and its Affiliates will not be treated as Affiliates of each other)
as Mortgagor or Tenant thereof; or

                  n. Advisor. RMR shall cease to be the sole Advisor to Borrower
pursuant to and in accordance with the Advisory Agreement, without Agent's prior
written  consent  or  the  Advisory  Agreement  shall  be  materially   amended,
supplemented or modified without Agent's prior written consent; or

                  o. Loan  Documents.  From and after the  Effective  Date,  any
guarantee  given by a Subsidiary  of Borrower in Section 9 or any Loan  Document
shall be terminated  or otherwise  shall cease to be in full force and effect or
shall cease to give the Lenders the rights,  powers and privileges  purported to
be created  thereby or any party  thereto other than Agent and the Lenders shall
cease to be, or shall assert that it is not,  bound thereby in  accordance  with
its terms; then, and in any such event, (a) if such event is an Event of Default
specified  in  paragraph  (g)  above,   automatically   the  Commitments   shall
immediately  terminate and the Loans hereunder (with accrued  interest  thereon)
and all other amounts owing under this  Agreement,  the Notes and any other Loan
Document shall immediately become due and payable,  and (b) if such event is any
other Event of Default,  either or both of the  following  actions may be taken:
(i) Agent may, or upon the request of the  Majority  Lenders,  Agent  shall,  by
notice  to  Borrower,  declare  the  Commitments  to  be  terminated  forthwith,
whereupon the Commitments  shall immediately  terminate;  and (ii) Agent may, or
upon the request of the Majority  Lenders,  Agent shall, by notice of default to
Borrower,  declare the Loans hereunder (with accrued  interest  thereon) and all
other amounts owing under this Agreement,  the Notes and any other Loan Document
to be due and payable forthwith, whereupon the same shall immediately become due
and payable.  Except as expressly  provided above in this Section,  presentment,
demand, protest and all other notices of any kind are hereby expressly waived.

                  7.2.  Annulment of  Acceleration.  If payment on the Loans and
the Notes is accelerated in accordance with Section 7.1 of this Agreement,  then
and in every such case, the Majority Lenders may, by an instrument  delivered to
Borrower (and to Agent and/or Administrative Agent, as applicable, to the extent
it is or they 

                                      -82-
<PAGE>
are not  participating in the giving of notice) annul such  acceleration and the
consequences thereof; provided that at the time such acceleration is annulled:

                  a. all  arrears or interest on the Loans and the Notes and all
other sums payable in respect of the Loans and pursuant to this  Agreement,  the
Notes and each other Loan  Document  (except  any  principal  of or  interest or
premium  on the Loans and the Notes and other  sums  which  have  become due and
payable only by reason of such acceleration) shall have been duly paid; and

                  b. every  other  Default  or Event of Default  shall have been
duly waived or otherwise cured; provided,  further, that no such annulment shall
extend to or affect  any  subsequent  Default  or Event of Default or impair any
right consequent thereon.

                  7.3.  Cooperation by Borrower.  To the extent that it lawfully
may,  Borrower agrees that it will not (and that it will cause its  Subsidiaries
not to) at any time insist  upon or plead,  or in any manner  whatever  claim or
take any  benefit  or  advantage  of any  applicable  present  or  future  stay,
extension or moratorium  law, which may affect  observance or performance of the
provisions of this Agreement or of any Note or any other Loan Document.

                              SECTION 8.THE AGENTS

                  8.1. Appointment of Agent and Administrative Agent.

                  a. Each Lender  hereby  irrevocably  designates  and  appoints
Dresdner  Kleinwort Benson North America LLC as Agent of such Lender and each of
Fleet  and the GBP  Agent  (as  defined  in the  definition  of  "Administrative
Agent"), as Administrative Agent of such Lender (with their respective functions
as set  forth in the  definition  of  "Administrative  Agent")  (the  Agent  and
Administrative Agent collectively being the "Loan Agents", and, for the purposes
of Sections  8.1(c),  8.1(g),  8.1(h) and 8.1(l),  each  Co-Agent  shall also be
deemed to be a "Loan Agent") under this Agreement and the Loan Documents and the
other documents or instruments  delivered pursuant to or in connection  herewith
or therewith and each such Lender hereby irrevocably authorizes each Loan Agent,
for such  Lender,  to take  such  action  on  behalf  of each  Lender  under the
provisions  of the Loan  Documents  and to exercise such powers and perform such
duties as are  expressly  delegated  to such Loan Agent by the terms of the Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding  any provision to the contrary  elsewhere in the Loan Documents,
no Loan  Agent  shall  have any  duties or  responsibilities  other  than  those
expressly set forth in the Loan Documents,  nor any fiduciary  relationship with
any  Lender,  and no implied  covenants,  functions,  

                                      -83-
<PAGE>
responsibilities, duties, obligations or liabilities shall be read into the Loan
Documents or otherwise  exist against either Loan Agent.  No Co-Agent  hereunder
shall  have  any  liability  to any  Person  under  this  Agreement  or the Loan
Documents except in its capacity as a Lender.

                  b. Each Loan Agent may  execute  any of its  duties  under the
Loan Documents by or through agents or  attorneys-in-fact  and shall be entitled
to advice of counsel  concerning all matters  pertaining to such duties. No Loan
Agent shall be  responsible  for the  negligence  or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

                  c.  None  of the  Loan  Agents  nor  any of  their  respective
officers, directors, employees, agents, attorneys-in-fact or affiliates shall be
(i) liable for any action  lawfully  taken or omitted to be taken by it under or
in  connection  with the Loan  Documents  (except  for its gross  negligence  or
willful  misconduct),  or (ii)  responsible  in any manner to any Lender for any
recitals,  statements,  representations or warranties made by Borrower or any of
its  Subsidiaries or any other Person  contained in the Loan Documents or in any
certificate, report, statement or other document referred to or provided for in,
or received by either Loan Agent under or in connection with, the Loan Documents
(including, without limitation, any Appraisal or valuation or any certificate or
other report relating to the value of any Property or any Mortgage Interest), or
for  the  value,  validity,   effectiveness,   genuineness,   enforceability  or
sufficiency of the Loan Documents or otherwise or for any failure of Borrower or
any of its Subsidiaries or any other Person to perform its obligations under the
Loan Documents.  The Loan Agents shall not be under any obligation to any Lender
to ascertain or to inquire as to the  observance  or  performance  of any of the
agreements contained in, or conditions of, the Loan Documents, or to inspect the
properties, books or records of Borrower or any of its Subsidiaries or any other
Person or to insure,  protect or preserve any of the property of Borrower or any
of its Subsidiaries or any other Person.

                  d. Each Loan Agent  shall be  entitled  to rely,  and shall be
fully protected in relying, upon any Note, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message,  statement, order or other document or conversation reasonably believed
by it to be genuine  and correct  and to have been  signed,  sent or made by the
proper  Person or  Persons  and upon  advice  and  statements  of legal  counsel
(including,  without  limitation,  counsel  to  Borrower  or its  Subsidiaries),
independent  accountants  and other  experts  selected by such or the other Loan
Agent.  Each  Loan  Agent  may deem and treat the payee of any Note as the owner
thereof for all purposes  unless a written notice of assignment,  negotiation or
transfer thereof shall have been filed with such Loan Agent.

                  e. Each Loan  Agent  shall be fully  justified  in  failing or
refusing  to take any  action  under the Loan  Documents  unless it shall  first
receive  such  advice  or  concurrence  of  the  Majority  Lenders  as it  deems
appropriate or it shall first be indemnified to 

                                      -84-
<PAGE>
its  satisfaction by the Lenders against any and all liability and expense which
may be incurred by it by reason of taking or continuing to take any such action.
Each  Loan  Agent  shall in all  cases  be  fully  protected  in  acting,  or in
refraining from acting, under the Loan Documents in accordance with a request of
the  Majority  Lenders,  and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Lenders and all future holders of
the Notes.

                  f. No Loan Agent shall be deemed to have  knowledge  or notice
of the occurrence of any Event of Default or event,  act or condition which with
notice or lapse of time, or both, would constitute an Event of Default hereunder
unless such Loan Agent shall have received  notice from the other Loan Agent,  a
Lender or Borrower  referring to this Agreement,  describing such event,  act or
condition  or Event of  Default  and  stating  that such  notice is a "notice of
default". In the event that a Loan Agent receives such a notice, such Loan Agent
shall give prompt notice thereof to the Lenders and (provided such notice is not
received  from the other Loan  Agent) to the other Loan  Agent.  Each Loan Agent
shall take such action  with  respect to the rights and  remedies  given to such
Loan Agent  pursuant to the terms of the Loan  Documents as shall be  reasonably
directed by the  Majority  Lenders;  provided  that,  unless and until such Loan
Agent shall have received such directions, such Loan Agent may (but shall not be
obligated to) take such action,  or refrain from taking such action, as it shall
deem advisable in the best interests of the Lenders.

                  g. Each Lender  expressly  acknowledges  that none of the Loan
Agents   nor   any   of   their   officers,   directors,    employees,   agents,
attorneys-in-fact or affiliates has made any representations or warranties to it
and that no act by either Loan Agent hereinafter taken or hereinbefore  taken in
connection with the Existing Loan Agreement, including any review of the affairs
of  Borrower  or any of its  Subsidiaries,  shall be  deemed to  constitute  any
representation  or  warranty  by that  Loan  Agent to any  Lender.  Each  Lender
represents to the Loan Agents that it has,  independently  and without  reliance
upon  either Loan Agent or any other  Lender,  and based on such  documents  and
information  as it  has  deemed  appropriate,  made  its  own  appraisal  of and
investigation  into the  business,  operations,  property,  financial  and other
condition and  creditworthiness  of Borrower and its Subsidiaries,  each Tenant,
each  Mortgagor and each Credit  Support  Obligor,  and made its own decision to
make  its  loans  hereunder  and  enter  into  this  Agreement,  and that it has
satisfied itself independently, without reliance on either of the Loan Agents or
any   of   their   respective   officers,    directors,    employees,    agents,
attorneys-in-fact  or  affiliates,  as to the  compliance  of  the  transactions
contemplated  hereby with all legal and  regulatory  requirements  applicable to
such Lender.  Each Lender expressly  acknowledges that its representation in the
previous  sentence shall not be restricted or construed in any way to import any
reliance on either  Loan Agent or any other  Lender as a result of any duties or
other actions which may have been  undertaken by that Loan Agent or 

                                      -85-
<PAGE>
other Lender in connection  with the Existing Loan  Agreement,  and,  where such
Lender is itself also a party to the Existing Loan Agreement, that such Lender's
decision  to make its Loans  hereunder  and enter  into this  Agreement  is made
independently  of its decisions to enter into the Existing Loan Agreement and to
make  any  loans   thereunder.   Each  Lender  also  represents  that  it  will,
independently  and without  reliance upon either Loan Agent or any other Lender,
and based on such documents and information as it shall deem  appropriate at the
time,  continue to make its own credit  analysis,  appraisals  and  decisions in
taking or not taking action under this Agreement, and to make such investigation
as it deems necessary to inform itself as to the business, operations, property,
financial  and  other  condition  and   creditworthiness  of  Borrower  and  its
Subsidiaries,  any Tenant,  any Mortgagor or any Credit Support Obligor.  Except
for notices,  reports and other documents  expressly required to be furnished to
the Lenders by that Loan Agent hereunder, neither Loan Agent shall have any duty
or  responsibility  to provide any Lender  with any credit or other  information
concerning the business, operations,  property, financial and other condition or
credit-worthiness  of  Borrower  and its  Subsidiaries  which  may come into its
possession  or the  possession  of any of its  officers,  directors,  employees,
agents, attorneys-in-fact or affiliates.

                  h. Each  Lender  agrees to  indemnify,  defend  (with  counsel
selected  by each Loan  Agent) and hold each Loan Agent in its  capacity as such
(to the extent not reimbursed by Borrower and without limiting the obligation of
Borrower  to do so),  and such  Loan  Agent's  respective  officers,  directors,
shareholders,  employees and agents,  ratably  according to the  aggregate  loan
percentages set forth opposite its name on Schedule 1 hereto, harmless for, from
and against any and all liabilities,  obligations,  losses, damages,  penalties,
actions,  judgments,  suits,  costs,  expenses  or  disbursements  of  any  kind
whatsoever  which  may at any time  (including  without  limitation  at any time
following  the  payment of the Notes) be imposed  on,  incurred  by or  asserted
against  such  Loan  Agent in any way  relating  to or  arising  out of the Loan
Documents  or the  transactions  contemplated  thereby  or any  action  taken or
omitted by such Loan Agent  under or in  connection  with any of the  foregoing;
provided  that no Lender  shall be liable for the payment of any portion of such
liabilities,  obligations,  losses,  damages,  penalties,  actions,  judgements,
suits,  costs,  expenses or  disbursements  resulting  primarily  from such Loan
Agent's willful  misconduct or gross negligence.  The agreements in this Section
shall survive the payment of the Notes.

                  i. Each Loan  Agent and its  affiliates  may make loans to and
generally  engage  in  any  kind  of  business  with  Borrower  or  any  of  its
Subsidiaries  as though  such Loan Agent were not a Loan Agent  hereunder.  With
respect  to its pro rata share of the Loan made or  extended  by it and any Note
issued to it, each Loan Agent  shall have the same rights and powers  under this
Agreement  as any Lender and may  exercise the same as though it were not a Loan
Agent.  The terms  "Lender" and  "Lenders"  shall include each Loan Agent in its
individual capacity.

                                      -86-
<PAGE>
                  j. A Loan Agent may resign as Loan Agent upon 30 days' written
notice to the Lenders.  In the event that a Loan Agent shall enter receivership,
then the Lenders  (other than the Lender which is acting as such Loan Agent,  if
applicable)  may,  by  unanimous  consent,  remove such Loan Agent as Loan Agent
under this Agreement. If a Loan Agent shall resign as such Loan Agent under this
Agreement  or a Loan Agent shall be removed,  then the  Majority  Lenders  shall
within  30 days of such  resignation  or  removal  or,  in the  absence  of such
appointment,  the  resigning or removed  Loan Agent  shall,  appoint a successor
agent for the  Lenders,  whereupon  such  successor  agent shall  succeed to the
rights,  powers  and  duties  of such  Loan  Agent,  and  the  term  "Agent"  or
"Administrative Agent", as applicable, shall mean such successor agent effective
upon its appointment,  and the former Loan Agent's rights,  powers and duties as
Loan Agent shall be terminated,  without any other or further act or deed on the
part of such former Loan Agent or any of the  parties to this  Agreement  or any
holders of the Notes. After any retiring Loan Agent's  resignation  hereunder as
Loan Agent or any Loan Agent's removal, the provisions of this Section 8.1 shall
inure to its benefit as to any actions  taken or omitted to be taken by it while
it was a Loan Agent under this Agreement.

                  k. Each Lender agrees to use its best efforts promptly upon an
officer  responsible for the  administration of this Agreement becoming aware of
any development or other information which may have a Material Adverse Effect or
MAC to notify the other  Lenders of the same.  Each Loan  Agent  agrees  that it
shall promptly deliver to each Lender copies of all notices, demands, statements
and communications  which such Loan Agent gives to Borrower,  except for routine
notices of payment due under the Loan Documents and other miscellaneous notices,
demands, statements and communications, the failure of delivery of which to each
Lender shall not have a material  adverse  effect on any Lender.  The  foregoing
notwithstanding, no Loan Agent shall have any liability to any Lender, nor shall
a cause of action  arise  against any Loan Agent,  as a result of the failure of
such Loan  Agent to  deliver to any Lender  any  notice,  demand,  statement  or
communication  required to be delivered by it under this Section 8.1(k),  except
to the extent such failure is due to the gross  negligence or wilful  misconduct
of such Loan Agent.

                  l. Each Loan Agent shall endeavor to exercise the same care in
administering  the Loan  Documents  as it  exercises  with  respect  to  similar
transactions  in  which  it  is  involved  and  where  no  other  co-lenders  or
participants  are  involved;  provided that the liability of such Loan Agent for
failing to do so shall be limited as provided  in the  preceding  paragraphs  of
this Section 8.1.

                  (m) Each Lender agrees that, as between it and any Loan Agent,
any Loan  Document or  Appraisal,  or other  report or document  with respect to
which the approval of such Lender is required  hereunder,  sent to it for review
shall be deemed  consented to by it for purposes of any approval  thereof by any
Loan Agent if such 

                                      -87-
<PAGE>

Lender does not give to such Loan Agent written notice of its objection  thereto
within five Business Days of its receipt thereof. The foregoing shall be for the
benefit  of such Loan  Agent  only and  shall not be deemed a consent  under any
other  provision of this Agreement or to confer any rights on Borrower or any of
its Subsidiaries under this Agreement in any manner whatsoever.

                  (n) The Agent may from time to time at its discretion nominate
one or more Lenders as Co-Agent,  taking into consideration the magnitude of the
Commitment offered or undertaken by such Lender.

                                   SECTION 9.
                              SUBSIDIARY GUARANTIES

                  9.1 Guaranties.

                  In order to induce the  Lenders  to enter into this  Agreement
and to make the Loans to Borrower  hereunder,  each Subsidiary of Borrower which
is identified on the signature pages of this Agreement, agrees as follows:

                  (a) Each such  Subsidiary of Borrower  hereby  unconditionally
(subject to the next paragraph) and irrevocably  guarantees,  as primary obligor
and not merely as  surety,  the full and  punctual  payment  (whether  at stated
maturity,  upon  acceleration  or  otherwise)  of  the  principal  and  interest
(including, without limitation, interest which, but for the filing of a petition
in bankruptcy with respect to Borrower would accrue hereunder) on all Loans made
to Borrower,  and the full and punctual  payment of all other amounts payable by
Borrower under this Agreement  (including  amounts that would become due but for
the  operation of the automatic  stay under Section  362(a) of the United States
Bankruptcy  Code).  Upon failure by Borrower to pay  punctually any such amount,
each such Subsidiary  shall forthwith on demand pay the amount not so paid as if
that Subsidiary instead of Borrower were expressed to be the principal obligor.

                  The  obligations  of each  Subsidiary  of Borrower  under this
Section 9 shall be limited to a maximum  aggregate  amount  equal to the largest
amount  that  would  not  render  its  obligations  subject  to  avoidance  as a
fraudulent  transfer  or  conveyance  under  Section  548 of the  United  States
Bankruptcy  Code or any applicable  provisions of comparable  state law, in each
case after giving  effect to all other  liabilities  of the relevant  Subsidiary
(contingent or otherwise) that are relevant under those laws.

                  In order to provide for just and equitable  contribution among
the  Subsidiaries  of Borrower,  each such  Subsidiary  agrees that if any other
Subsidiary  makes payments under this Section 9 in an aggregate amount in excess
of the net value of 

                                      -88-
<PAGE>
the benefits  received by such other  Subsidiary and its own  Subsidiaries  from
extensions of credit under this  Agreement,  then the Subsidiary  which has made
such  excess  payments  shall  have a right of  contribution  against  the other
Subsidiaries  of Borrower for such excess.  However,  this right of contribution
shall be subject to Section 9.1(e) in all respects.

                  Each Subsidiary of Borrower acknowledges that the giving by it
of this  guarantee is a condition  precedent to the making or maintenance of the
Loans to Borrower  and also  acknowledges  that a portion of the proceeds of the
Loans  may be  advanced  to it by  Borrower,  and  accordingly  the  obligations
guaranteed are being incurred for, and will inure to, its benefit.

                  (b) The obligations of each  Subsidiary of Borrower  hereunder
shall be unconditional,  irrevocable,  direct and absolute and, without limiting
the generality of the foregoing, shall not be released,  discharged or otherwise
affected by (and, to the fullest extent  permitted by law, each such  Subsidiary
waives its rights in connection with):

                  (i) any extension, increase, renewal, settlement,  compromise,
         waiver or release in respect of any  obligation of Borrower  hereunder,
         by operation of law or otherwise;

                  (ii) any  modification  or amendment of or  supplement to this
         Agreement;

                  (iii) any release, impairment, non-perfection or invalidity of
         any direct or indirect security (if any) for any obligation of Borrower
         under this Agreement;

                  (iv) any change in the trust existence, structure or ownership
         of Borrower,  or any insolvency,  bankruptcy,  reorganization  or other
         similar  proceeding  affecting  Borrower or its assets or any resulting
         release or discharge  of any  obligation  of Borrower  contained in the
         Agreement;

                  (v) the existence of any claim,  set-off or other rights which
         such  Subsidiary may have at any time against  Borrower,  any Lender or
         any other  Person,  whether in  connection  herewith  or any  unrelated
         transactions;  provided that nothing herein shall prevent the assertion
         of any such claim by separate suit or compulsory counterclaim;

                  (vi) any invalidity or unenforceability relating to or against
         Borrower  for  any  reason  of  this  Agreement,  or any  provision  of
         applicable  law or  regulation  purporting  to prohibit  the payment by
         Borrower of the  principal  or interest on any Loan or any other amount
         payable by Borrower under this Agreement; or

                  (vii) any other act or omission to act or delay of any kind by
         Borrower,  any  Lender  or any other  Person or any other  circumstance
         whatsoever  which  might,  but for the  provisions  of this  Section 9,
         constitute  a  legal  or  equitable  discharge  of or  defense  to such
         Subsidiary's obligations hereunder.

                  (c) Each such Subsidiary's  obligations hereunder shall remain
in full force and effect  until this  Agreement  shall have  terminated  and the
principal  and interest on all Loans and all other  amounts  payable by Borrower
hereunder shall have been paid in full. Each such Subsidiary further agrees that
its guarantee hereunder shall continue to be effective or be reinstated,  as the
case may be, if at any time  payments,  or any part thereof,  of principal of or
interest on any  obligation  of  Borrower  is  rescinded  or must  otherwise  be
restored  by Agent  or any  Lender  upon the  bankruptcy  or  reorganization  of
Borrower or otherwise.

                  (d) Each such Subsidiary irrevocably waives acceptance hereof,
presentment,  demand, protest and any notice not provided for herein, as well as
any  requirement  that at any time any  action  be taken by any  Person  against
Borrower or any other Person.

                  (e) Each Subsidiary  irrevocably  waives any and all rights to
which it may be  entitled,  by operation  of law or  otherwise,  upon making any
payment  hereunder to be subrogated to the rights of the payee against  Borrower
with  respect  to such  payment  or  against  any  direct or  indirect  security
therefor, or otherwise to be reimbursed, indemnified or exonerated by or for the
account of Borrower in respect thereof.

                  (f)  Any  Subsidiary   Guarantor  may  be  released  from  the
guarantee set forth in this Section 9 by a written release  executed by Agent on
behalf of the Lenders upon Agent's  satisfaction that such Subsidiary  Guarantor
has no remaining assets and is to be dissolved in accordance with clause (iv)(y)
of the proviso to Section 6.3(a).

                  10.4  No  Waivers;   Cumulative  Remedies;  Entire  Agreement;
Headings;  Successors and Assigns;  Counterparts;  Severability.  (a) No action,

Administrative Agent or any Lender hereunder or thereunder.

                  (b) No single or partial  exercise of any such  right,  power,
privilege or remedy shall preclude any other or further  exercise thereof or the
exercise of any other right, power,  privilege or remedy.  Such rights,  powers,
privileges and remedies are cumulative and not exclusive of any rights,  powers,
privileges and remedies provided by law or otherwise available,  including,  but
not limited to, rights to specific  performance (to the extent permitted by law)
or any  covenant or  agreement  contained  in this  Agreement or any of the Loan

                  (c) This  Agreement,  the Notes and the other  Loan  Documents
constitute  the entire  agreement of the parties  relating to the subject matter
hereof  and  thereof  and  there  are no verbal  agreements  relating  hereto or
thereto. Section headings herein shall have no legal effect.

                  (d) This  Agreement,  the Notes and the other  Loan  Documents
(including  all  covenants,   representations,   warranties,   rights,   powers,
privileges  and remedies made or granted  herein or therein)  shall inure to the
benefit of, and be enforceable by, Agent,  Administrative  Agent and each Lender
and their  respective  successors  and assigns,  except as  otherwise  expressly
provided in 

                                      -93-

this Agreement.  Neither  Borrower nor any of its  Subsidiaries  may directly or
indirectly  assign or transfer  (whether by  agreement,  by  operation of law or
otherwise) any of its rights or obligations  and liabilities  hereunder  without
the prior written consent of each Lender. Each of the Lenders may make, carry or
transfer  its pro rata share of the Loans at, to or for the  account  of, any of
its branch offices or the office of one or more of its Affiliates. Further, each
Lender may sell  participations  in all or any part of its pro rata share of the
Loans or its Commitments or any other interest herein or in its Notes to another
bank or Person,  or with the prior written consent of Agent and Borrower (not to
be unreasonably withheld; provided that Borrower's consent shall not be required
if an Event of Default has  occurred and is  continuing)  each Lender may assign
its rights and  delegate its  obligations  under this  Agreement  and any of the
other Loan  Documents and with the prior  written  consent of Agent and Borrower
(not to be unreasonably withheld;  provided that Borrower's consent shall not be
required if an Event of Default has occurred and is  continuing)  may assign all
or any part of its pro rata  share of the Loans or its  Commitment  or any other
interest  herein or in its Notes to another  bank or other Person in amounts not
less than  $5,000,000  (or any lesser amount in the case of an assignment by one
Lender to another Lender) to any one assignee, in which event (i) in the case of
an  assignment,  upon  notice  thereof  by such  Lender to  Borrower,  Agent and
Administrative  Agent  and upon  delivery  to the  Administrative  Agent for its
acceptance of an  Assignment  Agreement  executed by an assigning  Lender and an
assignee,  together with a processing  fee of $3,500  payable by the assignor or
the assignee to the Administrative Agent, the assignee shall have, to the extent
of such assignment (unless otherwise provided in the Assignment Agreement),  the
same rights and benefits as it would have if it were such Lender  hereunder  and
the  holder  of a Note and to such  extent  shall be deemed a  "Lender"  for all
purposes of this Agreement and the other Loan Documents, and (ii) in the case of
a participation,  the participant shall not have any rights under this Agreement
or any Note or any other Loan Document (the  participant's  rights  against such
Lender in respect of such  participation  to be those set forth in the agreement
executed by such Lender in favor of the participant  relating  thereto).  In the
case of such a participation,  the terms of the agreement or agreements pursuant
to which any such participation is created shall not confer upon the participant
any  right to vote its  interest  as a  participant  in  respect  of any  matter
relating to the Loans other than (w) the  extension  of the maturity of any Note
or the time of payment of interest  thereon,  (x) the  reduction  of the rate of
interest  payable  hereunder,  (y) the  reduction  of any other  amount  payable
hereunder  or (z) the  increase  of such  participant's  share  of the  relevant
Lender's  Commitment   hereunder.   Each  Lender  may  furnish  any  information
concerning Borrower and its Subsidiaries, the Advisor, any Tenant, any Mortgagor
and any Credit  Support  Obligor in the  possession  of such Lender from time to
time  to  assignees  and  participants   (including  prospective  assignees  and
participants).

                  (e) Each Lender  agrees  that such Lender  shall not assign or
offer to assign interests in its Notes in such a manner which would require that
the Notes be registered under applicable securities laws. Each Lender represents
that it is acquiring its  respective  Note for investment and not with a view to
or for sale in connection  with any  distribution  thereof within the meaning of
the  Securities  Act of 1933, as amended;  provided that the  disposition of the
Notes in accordance with the other  provisions of this Section 10.4 shall at all
times remain within the Lenders' control.

                  (f) This  Agreement  may be executed in any number of separate
counterparts,  each of which shall be deemed an original  and all of which taken
together shall be deemed to constitute one and the same instrument.

                  (g) In the event any one or more of the  provisions  contained
in this  Agreement  or any  Notes or any  other  Loan  Documents  should be held
invalid,  illegal or  unenforceable in any respect,  the validity,  legality and
enforceability of the remaining provisions contained herein or therein shall not
in any way be affected  or  impaired  thereby.  The  parties  shall  endeavor in
good-faith  negotiations  to  replace  the  invalid,  illegal  or  unenforceable
provisions with valid  provisions the economic effect of which comes as close as
possible to that of the invalid, illegal, or unenforceable provisions.

                  10.5 Survival. The obligations of Borrower under Sections 2.6,
2.10, 2.12, 2.13, 2.14, 2.15, 5.12 and 10.7 (and all other  indemnification  and
expense  reimbursement  obligations  of  Borrower  under this  Agreement)  shall
survive the  repayment  of the Loans and the  cancellation  of the Notes and the
termination of the other  obligations of Borrower  hereunder and under the other
Loan  Documents.  All  representations  and warranties made hereunder and in any
document,  certificate or statement  delivered  pursuant hereto or in connection
herewith  shall  survive the  execution  and delivery of this  Agreement and the
Notes and the funding of the Loans.

                  10.6  Amendments and Waivers.  With the written consent of the
Majority Lenders,  Agent and Borrower may, from time to time, enter into written
amendments,  supplements  or  modifications  hereto or to any of the other  Loan
Documents and with the written consent of the Majority Lenders,  Agent on behalf
of the Lenders may execute and deliver to Borrower a written instrument waiving,
on such terms and conditions as Agent may specify in such instrument, any of the
requirements  of this  Agreement or the Notes or any Default or Event of Default
and  its  consequences;  provided  that no such  waiver  and no such  amendment,
supplement or modification  shall (a) extend the maturity of any Note, or reduce
the rate or  extend  the time of  payment  of  interest  thereon,  or  reduce or
postpone  the due date for the  principal  amount  thereof  or any other  amount
payable in  connection  herewith,  or change the amount or terms of any Lender's

                                      -95-
<PAGE>
Commitment or amend, modify or waive any provision of this Section or reduce the
percentage  specified in the definition of Majority  Lenders,  or consent to the
assignment  or transfer by  Borrower  or any of its  Subsidiaries  of any of its
rights and obligations  under this  Agreement,  in each case without the written
consent of all the Lenders,  (b) amend, modify or waive any provision of Section
8 or otherwise  change any of the rights or obligations of either or both of the
Loan Agents under any of the Loan Documents  without the written  consent of the
affected Loan Agent or Loan Agents (as applicable) at the time, (c) with respect
to Section 6.7,  amend,  modify or waive (y) any  provision  thereof in a manner
which permits  Borrower or any of its Subsidiaries to own,  operate,  acquire or
fund income  producing real property  interests or facilities which do not offer
health care or related services or  rehabilitation  or retirement  services,  or
incidental  activities  to any of the  foregoing,  or (z) the proviso to Section
6.7,  without,  in the case of both  clauses (y) and (z) of this clause (c), the
written consent of the Majority Lenders,  Agent and Borrower  (provided that any
other  type of  amendment,  modification  or waiver of  Section  6.7 shall  only
require the written consent of the Majority Lenders,  Agent and Borrower) or (d)
amend,  modify or waive any  provision  of this Section 10.6 without the written
consent  of  all  Lenders.  In  the  case  of  any  waiver,   Borrower,   Agent,
Administrative  Agent and the Lenders shall be restored to their former position
and rights  hereunder and under the outstanding  Notes, and any Default or Event
of Default  waived shall be deemed to be cured and not  continuing;  but no such
waiver shall extend to any  subsequent or other Default or Event of Default,  or
impair any right consequent thereon.

                  10.7 Payment of Expenses and Taxes. Borrower agrees (a) to pay
or  reimburse  each of Agent  and  Administrative  Agent on  demand  for all its
out-of-pocket  costs and expenses  incurred in connection with the  development,
preparation and execution of, and any amendment,  supplement or modification to,
this  Agreement,  the Notes  and any other  Loan  Documents  or other  documents
prepared  in  connection  herewith,  and the  consummation  of the  transactions
contemplated hereby and thereby,  including,  without limitation, the reasonable
fees and disbursements of counsel to Agent and Administrative  Agent, (b) to pay
or reimburse each Lender,  Agent and Administrative  Agent on demand for all its
costs and expenses  incurred in connection  with the enforcement or preservation
of any rights under this Agreement,  the Notes, the other Loan Documents and any
such other documents,  or the satisfaction or review of conditions  precedent to
any  borrowing  other than that  occurring  on the  Effective  Date,  including,
without  limitation,  reasonable fees and  disbursements of counsel to Agent and
Administrative  Agent and, in the case of  enforcement  or  preservation  of any
rights under this  Agreement,  counsel to the several  Lenders,  and (c) to pay,
indemnify,  and to hold each Lender,  Agent and  Administrative  Agent and their
respective  officers,  directors,  employees  and agents  harmless for, from and
against,  any and all recording and filing fees and any and all liabilities with
respect  to, or  resulting  from 

                                      -96-
<PAGE>
any delay in paying, stamp, excise and other taxes, if any, which may be payable
or determined to be payable in connection with the execution and delivery of, or
consummation or  administration  of any of the transactions  contemplated by, or
any amendment,  supplement or modification of, or any waiver or consent under or
in respect of, this Agreement,  the Notes, the other Loan Documents and any such
other  documents,  and (d) to pay,  indemnify,  and hold each Lender,  Agent and
Administrative  Agent and their respective  officers,  directors,  employees and
agents   harmless  for,  from  and  against  any  and  all  other   liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses or disbursements  of any kind or nature  whatsoever with respect to the
execution, delivery,  enforcement,  performance and administration of, or in any
other way arising out of or relating to, this  Agreement,  the Notes,  the other
Loan Documents and any such other documents,  including, without limitation, any
claim resulting or arising out of the presence of Hazardous  Materials in any of
the Properties (all the foregoing, collectively, the "Indemnified Liabilities"),
provided  that  Borrower  shall have no  obligation  hereunder  with  respect to
Indemnified  Liabilities  arising  from (i) the willful  misconduct  of any such
Lender  or (ii)  legal  proceedings  commenced  against  any such  Lender by any
security  holder  or  creditor  thereof  arising  out of and based  upon  rights
afforded any such security holder or creditor solely in its capacity as such.

                  10.8 Adjustments; Setoff.

                  (a) If any Lender (a  "benefitted  Lender")  shall at any time
receive any payment of all or part of its Loan, or interest thereon,  or receive
any collateral in respect  thereof  (whether  voluntarily or  involuntarily,  by
set-off,  pursuant to events or proceedings of the nature  referred to in clause
(g) of Section 7.1, or otherwise) in a greater  proportion than any such payment
to or collateral  received by any other Lender, if any, in respect of such other
Lenders' Loan, or interest  thereon,  such benefitted  Lender shall purchase for
cash from the other  Lenders such portion of each such other  Lender's  Loan, or
shall  provide such other Lenders with the benefits of any such  collateral,  or
the proceeds  thereof,  as shall be necessary to cause such benefitted Lender to
share the excess payment or benefits of such collateral or proceeds ratably with
each of the Lenders;  provided that if all or any portion of such excess payment
or benefits is thereafter  recovered from such benefitted Lender,  such purchase
shall be rescinded,  and the purchase price and benefits returned, to the extent
of such  recovery,  but without  interest.  Borrower  expressly  consents to the
foregoing  arrangements  and agrees that each Lender so  purchasing a portion of
another  Lender's  Loan may exercise all rights of payment  (including,  without
limitation,  rights of set-off) with respect to such portion as fully as if such
Lender were the direct holder of such portion.

                  (b) In  addition  to any rights and  remedies  of the  Lenders

notice of every kind and,  to the full  extent  permitted  by law,  the right to

severally, for any obligation of, as claims against, the Borrower.

                  receive  any  such  payment  or  distribution  or any  benefit
                  therefrom  unless and until the Senior  Obligations  which are
                  then due and  payable (or in respect of which a proof of claim

                  SECTION 3.

                  3.1  The  Subordinated  Creditor  irrevocably  authorizes  and
empowers the  Administrative  Agent on behalf of the Senior  Creditors under the
circumstances set forth in clause (i) or (ii) of Section 2.2(b), to demand,  sue
for, collect and receive every such payment or distribution  referred to in such
Section and give acquittance therefor,  and take such other proceedings,  in the
name of the Senior  Creditors  or in the name of the  Subordinated  Creditor  or
otherwise,  as  the  Administrative  Agent  may  deem  reasonably  necessary  or
advisable for the enforcement of the subordination provisions of this Agreement.
The Subordinated  Creditor hereby agrees,  under the  circumstances set forth in
clause (i) or (ii) of Section  2.2(b),  duly and promptly to take such action as
may  be  reasonably  requested  at  any  time  and  from  time  to  time  by the
Administrative  Agent to file  appropriate  proofs  of claim in  respect  of the
Subordinated  Obligations,  and to execute and deliver  such powers of attorney,
assignments  or  other  instruments  as  may  be  reasonably  requested  by  the
Administrative  Agent in order to enable the  Administrative  Agent on behalf of
the Senior  Creditors  to enforce  any and all claims  upon or in respect of the
Subordinated  Obligations  and to collect and  receive  any and all  payments or
distributions which may be payable or deliverable at any time upon or in respect
of the Subordinated Obligations. Any such amounts received by the Administrative
Agent shall be applied  (subject to applicable law) to the payment of the Senior
Obligations pro rata in accordance with the amounts thereof then due and payable
(or in  respect  of which  proofs  of claim  have been  filed in any  applicable
proceeding)  and in the order of priority for payment of Senior  Obligations set
forth in the Loan Agreement.

                  3.2 Should any payment or  distribution  or  security,  or the
proceeds of any thereof,  be collected or received by the Subordinated  Creditor
pursuant to or in respect of the Subordinated  Obligations,  and such collection
or receipt is at the time prohibited hereunder (or the making of such payment or
distribution was so prohibited on the date of making thereof),  the Subordinated
Creditor will forthwith turn over the same to the  Administrative  Agent, in the
form received  (except for the endorsement or the assignment of the Subordinated
Creditor when  necessary)  and,  until so turned over, the same shall be held in
trust by the Subordinated Creditor as the property of the Senior Creditors.  Any
such amounts received by the  Administrative  Agent shall be applied (subject to
applicable law) to the payment of the Senior  Obligations pro rata in accordance
with the amounts  thereof then due and payable (or in respect of which proofs of
claim have been filed in any applicable proceeding) and in the order of priority
for payment of Senior Obligations set forth in the Loan Agreement.

                  3.3 (a) Subject to the  provisions  of  paragraph  (b) of this
Section 3.3, the Subordinated  Creditor shall be subrogated to the rights of the
Senior  Creditors  to receive  payments or  distributions  of cash,  property or
securities made on the Senior  Obligations until the Senior Obligations shall be
paid  in  full;  

                                      D-5
<PAGE>
and,  for the purposes of such  subrogation,  payments or  distributions  to the
Senior  Creditors of any cash,  property or securities to which the Subordinated
Creditor would be entitled except for the provisions of this Agreement shall, as
between the Borrower and its creditors  other than the Senior  Creditors and the
Subordinated  Creditor,  be  deemed  to be a payment  by the  Borrower  to or on
account of Subordinated Obligations,  it being understood that the provisions of
this  Agreement  are and are  intended  solely for the purpose of  defining  the
relative rights of the  Subordinated  Creditor,  on the one hand, and the Senior
Creditors, on the other hand. The purpose of this Section 3.3 is to grant to the
Subordinated  Creditor the same rights  against the Borrower with respect to the
aggregate amount of such payments or distributions as the Senior Creditors would
have  against the  Borrower if such  aggregate  amount were  considered  overdue
Senior Obligations.

                  (b)  Notwithstanding  any  payment  or  payments  made  by the
Subordinated  Creditor hereunder or any application of funds of the Subordinated
Creditor by the  Administrative  Agent or any Senior Creditor,  the Subordinated
Creditor  shall not be  entitled  to be  subrogated  to any of the rights of any
Senior Creditor against the Borrower or against or under any collateral security
or  guarantee  or right  of  offset  held by or for the  benefit  of any  Senior
Creditor for the payment of the Senior  Obligations,  nor shall the Subordinated
Creditor  seek any  reimbursement  from the  Borrower  or  against  or under any
collateral  security or guarantee or right of offset in respect of payments made
by the Subordinated  Creditor hereunder,  until all amounts owing to each Senior
Creditor by the Borrower for or on account of the Senior Obligations are finally
paid in full.

                  SECTION 4.

                  4.1  The  Subordinated   Creditor  represents,   warrants  and
covenants that:

                           (a)  The   Advisory   Agreement   delivered   to  the

                  Obligation  of the  Borrower to the Advisor and of the Advisor
                  to the Borrower;

                           (b) Subordinated  Obligations  currently or hereafter

                  liens,  charges  or  encumbrances   whatsoever  arising  from,
                  through  or under the  Subordinated  Creditor  other  than the
                  interest of the Senior  Creditors  under this  Agreement,  and
                  (ii) are or will be  payable  solely  and  exclusively  to the
                  Subordinated  Creditor and to no other  Person  (other than to
                  the  Administrative  Agent on behalf of the  Senior  Creditors
                  hereunder),  without  deduction  for any  defense,  offset  or
                  counterclaim;

                  holders of any indebtedness or obligations of the Subordinated
                  Creditor  (other than those which have been obtained) and will
                  not violate any  Requirement of Law or Contractual  Obligation
                  applicable to the Subordinated Creditor;

                           (d) no consent,  authorization  of,  filing with,  or
                  other act by or in respect of any  Governmental  Authority  is
                  required  in  connection  with the  authorization,  execution,
                  delivery and performance by the Subordinated  Creditor of this
                  Agreement  (other than those which have been  obtained and are
                  in full force and effect); and

                  binding obligation of the Subordinated  Creditor,  enforceable
                  against  the  Subordinated  Creditor  in  accordance  with its
                  terms,  except as may be  limited by  bankruptcy,  insolvency,

                  Subordinated Creditor as debtor or insolvent.

                  4.2 The Borrower represents, warrants and covenants that:

                           (a) the Borrower has full power,  authority and legal
                  right to execute,  deliver and perform this Agreement, and the
                  execution,  delivery and  performance  of this  Agreement have
                  been duly  authorized by all  necessary  action on the part of
                  the Borrower, do not require any authorization or other action
                  on the part of its  shareholders,  do not require any approval
                  or consent of any  trustee or holders of any  indebtedness  or
                  obligations of the Borrower  (other than those which have been
                  obtained)  and  will not  violate  any  Requirement  of Law or
                  Contractual Obligation applicable to the Borrower;

                           (b) no consent,  authorization  of,  filing with,  or
                  other act by or in respect of any  Governmental  Authority  is
                  required  in  connection  with the  authorization,  execution,
                  delivery and  performance  by the  Borrower of this  Agreement
                  (other  than those  which have been  obtained  and are in full
                  force and effect); and

                                      D-7
<PAGE>
                           (c) this  Agreement  constitutes  a legal,  valid and
                  binding  obligation of the Borrower,  enforceable  against the
                  Borrower  in  accordance  with  its  terms,  except  as may be
                  limited by bankruptcy, insolvency, reorganization,  moratorium
                  or similar laws  affecting  enforcement  of creditors'  rights
                  generally applicable to, and in any proceeding under such laws
                  relating to, the Borrower as debtor or insolvent.

                  SECTION 5.

                  5.1 No payment or payments  made by the  Borrower or any other
Person or  received  or  collected  by the  Administrative  Agent or any  Senior
Creditor  from the  Borrower  or any other  Person  by  virtue of any  action or
proceeding or any set-off or  appropriation  or  application at any time or from
time to time in reduction or payment of the Senior  Obligations  shall be deemed
to  modify,   reduce,  release  or  otherwise  affect  the  obligations  of  the
Subordinated  Creditor hereunder or the subordination  provided for herein which
shall,  notwithstanding any such payment or payments,  continue until the Senior
Obligations  are paid in full. The  Subordinated  Creditor hereby consents that,
without the  necessity of any  reservation  of rights  against the  Subordinated
Creditor and without notice to or further assent by the  Subordinated  Creditor,
any  demand  for  payment  of  any  of  the  Senior   Obligations  made  by  the
Administrative Agent or any Senior Creditor may be rescinded in whole or in part
by the  Administrative  Agent  or such  Senior  Creditor  and any of the  Senior
Obligations continued, and the Senior Obligations, or the liability of any other
party upon or for any part thereof, and the Loan Agreement, other Loan Documents
or any other collateral security document, collateral security or guarantee from
time to time  therefor  or  relating  thereto,  or other  document or right with
respect thereto,  with respect to the Senior Creditors or any particular  Senior
Creditor  may,  from time to time,  in whole or in part,  be renewed,  extended,
amended,  modified,  supplemented,   accelerated,   compromised,  waived,  sold,
exchanged,  or be surrendered or released or terminated or be unconsummated,  or
otherwise dealt with in any manner specified above or otherwise,  in whole or in
part, as such Senior Creditor or Senior  Creditors or the  Administrative  Agent
may  deem  advisable  from  time to  time,  all  without  the  necessity  of any
reservations of rights against the  Subordinated  Creditor and without notice to
or  further  assent  by the  Subordinated  Creditor,  which  will  remain  bound
hereunder  and all without  affecting  the  subordination  provided  for herein,
notwithstanding any of the foregoing events or circumstances. The Administrative
Agent and the Senior Creditors shall have no obligation or duty to take, accept,
protect,  secure,  perfect,  preserve  or insure,  or enforce or make  demand in
respect  of,  any  security  interest,   pledge,   mortgage  or  other  lien  or
encumbrance,  collateral  security  document or collateral  security at any time
held  or  contemplated  to  be  held  as  security  for,  or  any  guarantee  or
contemplated guarantee of, the Senior Obligations. When making

                                       D-8
<PAGE>

any demand hereunder against the Subordinated Creditor, the Administrative Agent
may in its sole discretion,  but shall be under no obligation to, make a similar
demand on the Borrower or any  co-obligor or guarantor,  or proceed  against any
collateral  security or under any collateral  security  document or guarantee or
other document or right, and any failure by the Administrative Agent to make any
such demand or to collect any payments from the Borrower or any such  co-obligor
or guarantor, or proceed against any collateral security or under any collateral
security document or guarantee or other document or right, or any release of the
Borrower  or  such  co-obligor  or  guarantor  or  under  or in  respect  of any
collateral  security or any collateral  security  document or guarantee or other
document or right,  shall not affect the  subordination  provided  for herein or
relieve the Subordinated  Creditor of its obligations or liabilities  hereunder,
and shall not impair or affect the rights and remedies,  express or implied,  or
as a matter of law, of the  Administrative  Agent or any Senior Creditor against
the  Subordinated  Creditor.  For the purposes hereof "demand" shall include the
commencement and continuance of any legal proceedings.

                  5.2 The Subordinated  Creditor  irrevocably waives any and all
notice of the  creation,  renewal,  extension  or  accrual  of any of the Senior
Obligations  and notice of or proof of reliance by any Senior Creditor upon this
Agreement,  and the Senior  Obligations,  existing and future,  and all dealings
between the Borrower or the Subordinated  Creditor and the Administrative  Agent
and each Senior  Creditor,  and any of them,  shall  conclusively  be deemed and
presumed to have been  created,  contracted,  incurred,  had or  consummated  in
reliance upon this  Agreement.  The  Subordinated  Creditor  irrevocably  waives
notice of or proof of reliance on this Agreement and diligence,  protest, demand
for payment and notice of default or  nonpayment  and any other notice or demand
whatsoever to or upon the Borrower or the Subordinated  Creditor with respect to
the  Senior  Obligations  and any right to  notice  of resale of any  collateral
security (if any),  and, in respect of the  Administrative  Agent and the Senior
Creditors,  any other rights of a "debtor" under the Uniform  Commercial Code as
in effect  from  time to time in the  State of New York (or any  other  relevant
jurisdiction) (collectively, the "UCC"), and irrevocably agrees not to assert in
any suit,  action or other  legal  proceeding  relating  to this  Agreement,  or
otherwise,  that it has, in respect of the  Administrative  Agent and the Senior
Creditors, status as, or any rights of, a "debtor" under the UCC, or any defense
to or discharge of its obligations  hereunder or the subordination  contemplated
herein  based  on any such  rights.  This  Agreement  shall  be  construed  as a
continuing, absolute, unconditional and irrevocable subordination without regard
to the validity,  regularity or enforceability of any of the Loan Documents, any
of the Senior  Obligations or any security interest,  pledge,  mortgage or other
lien or  encumbrance,  or  other  collateral  security  or  collateral  security
document, or any guarantee therefor or other

                                      D-9
<PAGE>
document or right with respect  thereto at any time or from time to time held by
or in favor of any Senior Creditor and without regard to any defense, set-off or
counterclaim  which  may at any  time  be  available  to or be  asserted  by the
Borrower,   the   Subordinated   Creditor  or  any  other  Person   against  the
Administrative  Agent  or  any  Senior  Creditor,   or  any  other  circumstance
whatsoever  (with or  without  notice to or  knowledge  of the  Borrower  or the
Subordinated  Creditor  or any  other  Person)  which  constitutes,  or might be
construed  to  constitute,  an  equitable  or legal  discharge or defense of the
Borrower  for or to any of the  Senior  Obligations,  or an  equitable  or legal
discharge  or defense of the  Subordinated  Creditor  under  this  Agreement  or
otherwise,  in bankruptcy or in reorganization or in any other instance, and the
obligations  and  liabilities  of the  Subordinated  Creditor  hereunder and the
subordination  contemplated  herein shall not be conditioned or contingent  upon
the pursuit by the Administrative Agent, any Senior Creditor or any other Person
at any time of any right or remedy  against  the  Borrower  or against any other
Person which may be or become liable in respect of all or any part of the Senior
Obligations or against or under any security interest, pledge, mortgage or other
lien or  encumbrance,  or  other  collateral  security  or  collateral  security
document, or any guarantee or other document or right with respect thereto. This
Agreement  shall  remain in full force and  effect and be binding in  accordance
with and to the  extent  of its terms  upon the  Borrower  and the  Subordinated
Creditor and the successors and assigns thereof,  and shall inure to the benefit
of each Senior Creditor, and its successors, endorsees, transferees and assigns,
until the Loan Agreement and all other Loan  Documents  have been  terminated in
accordance  with their terms and all the Senior  Obligations and the obligations
and  liabilities of the  Subordinated  Creditor under this Agreement  shall have
been satisfied by final payment or performance in full.

                  5.3 This  Agreement  shall  continue  to be  effective,  or be
reinstated,  as the case may be, if at any time payment, or any part thereof, of
any of the Senior  Obligations  is  rescinded  or must  otherwise be restored or
returned by any Senior  Creditor upon the insolvency,  bankruptcy,  dissolution,
liquidation or reorganization of the Borrower or the Subordinated  Creditor,  or
upon or as a result of the appointment of a receiver,  intervenor or conservator
of, or trustee or similar officer for, the Borrower or the Subordinated Creditor
or any substantial  part of their respective  property,  or for any other reason
whatsoever, all as though such payments had not been made.

                  SECTION 6.

                  6.1 The Subordinated  Creditor will not (a) sell,  assign,  or
otherwise  transfer,  in whole or in part, the  Subordinated  Obligations or any
interest therein to any Person unless (x) such Person has expressly acknowledged
to the  Administrative  Agent, in writing in form and substance  satisfactory to
the Administrative 

                                      D-10
<PAGE>

Agent, the  subordination  provided for herein and agrees to be bound by all the
terms hereof, and (y) the Subordinated  Creditor has expressly guaranteed to the
Administrative  Agent,  in writing  in form and  substance  satisfactory  to the
Administrative   Agent,   the  performance  by  such  Person  of  such  Person's
obligations under Section 3.2 of this Agreement;  or (b) create, incur or suffer
to exist any security  interest,  lien, charge or other  encumbrance  whatsoever
upon the Subordinated Obligations in favor of any Person unless the Subordinated
Creditor has  obtained the prior  written  consent of the  Administrative  Agent
(which consent may be withheld in the  Administrative  Agent's sole  discretion)
and such Person expressly  acknowledges to the  Administrative  Agent in writing
the subordination provided for herein and agrees to be bound by all of the terms
hereof.  Without  the prior  written  consent  of the  Administrative  Agent the
Subordinated Creditor and the Borrower will not amend or supplement the Advisory
Agreement as in effect on the date hereof or enter into any other agreement that
directly or indirectly (a) increases the Subordinated Obligations payable to the
Advisor or modifies the basis on which any Subordinated  Obligations are payable
in a manner which could  increase the  Subordinated  Obligations  payable to the
Advisor or provides for any  additional  Subordinated  Obligations to be paid to
the Advisor, or (b) provides for or results in Subordinated Obligations becoming
due and payable  earlier than is  contemplated  by the Advisory  Agreement as in
effect on the date hereof or (c)  provides for or results in any services of the
Advisor  contemplated  by the Advisory  Agreement  being performed by any Person
(including any Affiliate of the Advisor) other than the Advisor.

                  6.2  Except as  otherwise  expressly  set forth  herein,  this
Agreement is intended to create a relationship among independent contractors and
nothing in this Agreement shall be deemed to create a fiduciary, agency or trust
relationship in favor of the Advisor or the Borrower.

                  6.3 The Advisor hereby  acknowledges  receipt of copies of the
Loan Agreement and all other Loan Documents.

                  7.4  No  Waivers;   Cumulative  Remedies;   Entire  Agreement;
Headings;  Successors  and  Assigns;  Counterparts;   Severability.  No  action,
failure,  delay or omission by the Administrative Agent in exercising any rights
and remedies under the Loan Agreement or any of the other Loan  Documents,  this
Agreement or  otherwise,  shall  constitute  a waiver of, or impair,  any of the
rights or  privileges  of any Senior  Creditor  hereunder.  No single or partial
exercise  of any such  right or  remedy  shall  preclude  any  other or  further
exercise  thereof or the exercise of any other right or remedy.  Such rights and
remedies are cumulative and not exclusive of any rights and remedies provided by
law or  otherwise  available.  No  waiver of any such  right or remedy  shall be
effective unless given in writing by the Administrative  Agent. No waiver of any
such  right or remedy  shall be  deemed a waiver  of any  other  right or remedy
hereunder or  thereunder.  Every right and remedy given by this  Agreement or by
applicable  law to or for the benefit of any Senior  Creditor  may be  exercised
from time to time and as often as may be deemed expedient by the  Administrative
Agent on behalf of such Senior  Creditor.  Except as expressly set forth herein,
this Agreement  constitutes the entire  agreement of the parties relating to the
subject  matter hereof and thereof and there are no verbal  agreements  relating
hereto or thereto.  Section  headings  herein shall have no legal  effect.  This
Agreement  (including all covenants,  representations,  warranties,  privileges,
rights,  and  remedies  made or granted  herein or  therein)  shall inure to the
benefit of, and be enforceable  by, the  Administrative  Agent on behalf of each
Senior  Creditor and its successors and assigns,  except as otherwise  expressly
provided  in this  Agreement.  The  Subordinated  Creditor  may not  directly or
indirectly  assign or transfer  (whether by  agreement,  by  operation of law or
otherwise) any of its rights or obligations  and liabilities  hereunder  without
the prior written consent of the Administrative  Agent. Each Senior Creditor may
grant  participations  in or  otherwise  sell or  dispose  of, any of its rights
hereunder to the extent  permitted by and in accordance  with the  provisions of
the Loan  Agreement.  This  Agreement  may be executed in any number of separate
counterparts,  each of which shall be deemed an original  and all of which taken
together shall be deemed to constitute one and the same instrument. In the event
any one or more of the  provisions  contained in this  Agreement  should be held
invalid,  illegal or  unenforceable in any respect,  the validity,  legality and
enforceability of the remaining provisions contained herein or therein shall not
in any way be affected  or  impaired  thereby.  The  parties  shall  endeavor in
good-faith  negotiations  to  replace  the  invalid,  illegal  or  unenforceable
provisions with valid  provisions the economic effect of which comes as close as
possible to that of the invalid, illegal, or unenforceable provisions.

                  7.5  The  obligations  of the  Subordinated  Creditor  and the
Borrower  under this  Agreement  shall survive the repayment of the Loan and the
cancellation  of the Notes and the  termination  of the 

                                      D-14
<PAGE>

other Loan Documents and the Senior Obligations,  in the circumstances described
in Section 5.3.

                  7.6 The  Subordinated  Creditor  and  the  Borrower  agree  to
execute and deliver such further  documents and to do such other acts and things
as the Administrative  Agent may reasonably request in order fully to effect the
purposes of this Agreement.

                  7.7 The subordination  provisions contained herein are for the
benefit  of  the  Administrative  Agent  and  the  Senior  Creditors  and  their
respective  successors  and  assigns  as  holders  from  time to time of  Senior
Obligations  and may not be rescinded or cancelled or modified in any way,  nor,
unless  otherwise  expressly  provided  for herein,  may any  provision  of this
Agreement be waived or changed without the express prior written consent thereto
of the Administrative Agent.

                  7.8 The Borrower  and  Subordinated  Creditor  will cause each
executed  copy of the  Advisory  Agreement,  any  instrument  or  other  writing
evidencing  any  of  the  obligations  arising  thereunder  and  any  amendment,
modification  or supplement  thereto to bear a statement or legend to the effect
that the Subordinated Obligations are subordinate and junior in right of payment
to the Senior Obligations in the manner and to the extent herein set forth.

                  7.9 For purposes of this Agreement,  Senior  Obligations shall
cease to be such, or the  outstanding  principal  amount thereof shall be deemed
reduced,  only (i) upon actual receipt by the Subordinated  Creditor of a notice
from the holder or holders of such  Senior  Obligations  or obligee or  obligees
with  respect  thereto   terminating  the  constitution  of  such  indebtedness,
obligations  and/or  liabilities as senior  obligations  under this Agreement or
reducing the amount of such  indebtedness,  obligations  and/or  liabilities  so
constituted or (ii) when the Senior  Obligations  have in fact been finally paid
in full and the Loan Agreement and all other Loan Documents have been terminated
in accordance with their terms and the Subordinated Creditor shall have received
notice from the  Administrative  Agent of such fact.  The  Administrative  Agent
shall within seven Business Days following receipt of a written request therefor
from the Subordinated  Creditor confirm in writing to the Subordinated  Creditor
whether or not the Senior Obligations have ceased to be such, pursuant to clause
(ii) of the previous sentence.  At the request of the Administrative  Agent, the
Subordinated  Creditor  will confirm in writing to any Senior  Creditor that the
indebtedness,  obligations  and/or  liabilities held by such Senior Creditor and
constituted as Senior Obligations hereunder are Senior Obligations. However, the
failure or refusal of the Subordinated  Creditor to issue any such  confirmation
shall  not  affect  the  status  as  Senior  Obligations  of  any  indebtedness,
obligations  and/or  liabilities  constituting  Senior Obligations in accordance
with the provisions of this Agreement.

                         [FORM OF ASSIGNMENT AGREEMENT]

                              ASSIGNMENT AGREEMENT


                  This ASSIGNMENT  AGREEMENT (this  "Agreement") is entered into
by and between the parties  designated  as Assignor  ("Assignor")  and  Assignee
("Assignee")  above the  signatures  of such  parties on the  Schedule  of Terms
attached  hereto and hereby made an  integral  part  hereof  (the  "Schedule  of
Terms") and relates to that certain Loan Agreement  described in the Schedule of
Terms (said Loan Agreement,  as amended,  supplemented or otherwise  modified to
the date hereof and as it may  hereafter be amended,  supplemented  or otherwise
modified  from  time to time,  being  the "Loan  Agreement",  the terms  defined
therein and not otherwise defined herein being used herein as therein defined).

                  IN CONSIDERATION  of the agreements,  provisions and covenants
herein contained, the parties hereto hereby agree as follows:

                  SECTION 1.  Assignment and Assumption.

                  (a) Effective upon the Settlement  Date specified in Item 4 of
the Schedule of Terms (the "Settlement Date"), Assignor hereby sells and assigns
to Assignee,  without recourse,  representation or warranty (except as expressly
set forth herein), and Assignee hereby purchases and assumes from Assignor, that
percentage  interest in all of  Assignor's  rights and  obligations  as a Lender
arising under the Loan  Agreement and the other Loan  Documents  with respect to
Assignor's  Commitments and outstanding  Loans, if any, which represents,  as of
the Settlement Date, the percentage interest specified in Item 3 of the Schedule
of Terms of all  rights  and  obligations  of  Lenders  arising  under  the Loan
Agreement and the other Loan Documents with respect to the  Commitments  and any
outstanding Loans (the "Assigned Share").

                  (b)  In  consideration  of  the  assignment  described  above,
Assignee hereby agrees to pay to Assignor, on the Settlement Date, the principal
amount of any outstanding Loans included within the Assigned Share, such payment
to be made by wire transfer of immediately  available  funds in accordance  with
the  applicable  payment  instructions  set forth in Item 5 of the  Schedule  of
Terms.

                  (c) Assignor hereby represents and warrants that Item 3 of the
Schedule  of Terms  correctly  sets  forth the  amount of the  Commitments,  the
outstanding Loans and the Pro Rata Share corresponding to the Assigned Share.

<PAGE>

                  (d)  Assignor  and  Assignee  hereby  agree that,  upon giving
effect to the assignment and assumption described above, (i) Assignee shall be a
party to the Loan  Agreement  and shall have all of the  rights and  obligations
under the Loan Documents,  and shall be deemed to have made all of the covenants
and  agreements  contained  in the Loan  Documents,  arising out of or otherwise
related to the Assigned  Share,  and (ii) Assignor shall be absolutely  released
from  any of such  obligations,  covenants  and  agreements  assumed  or made by
Assignee in respect of the Assigned  Share.  Assignee  hereby  acknowledges  and
agrees that the agreement  set forth in this Section 1(d) is expressly  made for
the benefit of the Borrower, Agent, Administrative Agent, Assignor and the other
Lenders and their respective successors and permitted assigns.

                  (e) Assignor and Assignee hereby acknowledge and confirm their
understanding  and intent that (i) this Agreement shall effect the assignment by
Assignor and the  assumption  by Assignee of Assignor's  rights and  obligations
with respect to the Assigned Share,  (ii) any other assignments by Assignor of a
portion of its rights and  obligations  with respect to the  Commitments and any
outstanding Loans shall have no effect on the Commitments, the outstanding Loans
and the Pro Rata Share  corresponding to the Assigned Share as set forth in Item
3 of the  Schedule of Terms or on the  interest  of Assignee in any  outstanding
Loans corresponding thereto, and (iii) from and after the Settlement Date, Agent
shall make all  payments  under the Loan  Agreement  in respect of the  Assigned
Share  (including  all  payments of principal  and accrued but unpaid  interest,
commitment fees and letter of credit fees with respect  thereto) (A) in the case
of any such  interest and fees that shall have accrued  prior to the  Settlement
Date,  to Assignor,  and (B) in all other  cases,  to  Assignee;  provided  that
Assignor and Assignee  shall make payments  directly to each other to the extent
necessary to effect any  appropriate  adjustments in any amounts  distributed to
Assignor  and/or  Assignee by Agent under the Loan  Documents  in respect of the
Assigned  Share in the event  that,  for any reason  whatsoever,  the payment of
consideration  contemplated  by  Section  1(b)  occurs on a date  other than the
Settlement Date.

                  SECTION 2.  Certain Representations, Warranties and
Agreements.

                  (a) Assignor  represents and warrants that it is the legal and
beneficial owner of the Assigned Share, free and clear of any adverse claim.

                  (b)  Assignor  shall not be  responsible  to Assignee  for the
execution, effectiveness, genuineness, validity, enforceability,  collectibility
or  sufficiency  of any of  the  Loan  Documents  or  for  any  representations,
warranties,  recitals or statements  made therein or made in any written or oral
statements  or in any  financial or other  statements,  instruments,  reports or
certificates or any other documents furnished or made by Assignor 

                                      E-2
<PAGE>

to Assignee or by or on behalf of the  Borrower  or any of its  Subsidiaries  to
Assignor or Assignee in connection with the Loan Documents and the  transactions
contemplated  thereby or for the financial  condition or business affairs of the
Borrower or any other Person liable for the payment of any obligations under the
Loan Agreement, nor shall Assignor be required to ascertain or inquire as to the
performance or observance of any of the terms, conditions, provisions, covenants
or  agreements  contained  in any of the Loan  Documents or as to the use of the
proceeds of the Loans or as to the existence or possible  existence of any Event
of Default or potential Event of Default.

                  (c) Assignee  represents  and warrants that it has  experience
and expertise in the making of loans such as the Loans; that it has acquired the
Assigned  Share for its own account in the  ordinary  course of its business and
without a view to distribution of the Loans within the meaning of the Securities
Act or the Exchange Act or other federal  securities  laws (it being  understood
that,  subject to the provisions of subsection 10.4 of the Loan  Agreement,  the
disposition  of the Assigned  Share or any interests  therein shall at all times
remain within its  exclusive  control);  and that it has received,  reviewed and
approved a copy of the Loan  Agreement  (including  all Exhibits  and  Schedules
thereto).

                  (d) Assignee represents and warrants that it has received from
Assignor such financial  information regarding the Borrower and its Subsidiaries
as is available to Assignor and as Assignee has requested,  that it has made its
own  independent  investigation  of the  financial  condition and affairs of the
Borrower and its  Subsidiaries  in connection  with the assignment  evidenced by
this  Agreement,  and  that it has  made  and  shall  continue  to make  its own
appraisal of the creditworthiness of the Borrower and its Subsidiaries. Assignor
shall have no duty or responsibility, either initially or on a continuing basis,
to make any such investigation or any such appraisal on behalf of Assignee or to
provide  Assignee  with any  other  credit  or other  information  with  respect
thereto,  whether  coming into its  possession  before the making of the initial
Loans  or at any time or  times  thereafter,  and  Assignor  shall  not have any
responsibility  with  respect  to the  accuracy  of or the  completeness  of any
information provided to Assignee.

                  (e) Each party to this  Agreement  represents  and warrants to
the other party  hereto that it has full power and  authority to enter into this
Agreement  and to perform  its  obligations  hereunder  in  accordance  with the
provisions  hereof,  that this Agreement has been duly authorized,  executed and
delivered by such party and that this Agreement  constitutes a legal,  valid and
binding obligation of such party,  enforceable  against such party in accordance
with  its  terms,   except  as  enforceability  may  be  limited  by  applicable
bankruptcy,  insolvency,  reorganization,   moratorium  or  other  similar  laws
affecting creditors' rights generally and by general principles of equity.

                  SECTION 3.  Miscellaneous.

                  (a) Each of Assignor and Assignee  hereby  agrees from time to
time,  upon  request  of the other such party  hereto,  to take such  additional
actions and to execute and deliver such additional  documents and instruments as
such other party may reasonably request to effect the transactions  contemplated
by, and to carry out the intent of, this Agreement.

                  (b) Neither this Agreement nor any term hereof may be changed,

to or acceptance of this  Agreement)  against whom  enforcement  of such change,
waiver, discharge or termination is sought.

                  (c) Unless otherwise  specifically provided herein, any notice
or other  communication  herein  required or  permitted  to be given shall be in
writing and may be personally served, telexed or sent by telefacsimile or United
States  mail or  courier  service  and shall be deemed to have been  given  when
delivered  in person or by courier  service,  upon receipt of  telefacsimile  or
telex, or three Business Days after depositing it in the United States mail with
postage  prepaid and properly  addressed.  For the purposes  hereof,  the notice
address of each of Assignor and  Assignee  shall be as set forth on the Schedule
of Terms or, as to either such party,  such other address as shall be designated
by such  party in a  written  notice  delivered  to the  other  such  party.  In
addition,  the notice  address of  Assignee  set forth on the  Schedule of Terms
shall serve as the initial notice address of Assignee for purposes of subsection
10.3 of the Loan Agreement.

                  (d)  In  case  any  provision  in  or  obligation  under  this
Agreement shall be invalid,  illegal or unenforceable in any  jurisdiction,  the
validity,   legality  and   enforceability   of  the  remaining   provisions  or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby.

                  (e) THIS  AGREEMENT  AND THE  RIGHTS  AND  OBLIGATIONS  OF THE
PARTIES  HEREUNDER  SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN
ACCORDANCE  WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK (INCLUDING  SECTION

executed and delivered  shall be deemed an original,  but all such  counterparts
together shall constitute but one and the same  instrument;  signature pages may

                                   SCHEDULE 5

                       CALCULATION OF THE MANDATORY LIQUID
                          ASSET COSTS FOR ANY GBP LOANS



(a)  The Mandatory  Liquid Asset Costs for a Loan if denominated in GBP for each
     Interest  Period  for  that  Loan is  calculated  in  accordance  with  the
     following formula:

                        BY + L(Y-X) + S(Y-Z)% PER ANNUM
                                 100 - (B+S)

     where on the day of the application of the formula:

     B    is the percentage of Agent's  eligible  liabilities  which the Bank of
          England then requires Agent to hold on a non-interest-bearing  deposit
          account in accordance with its cash ratio requirements;

     Y    is the rate at which GBP  deposits  are  offered  by Agent to  leading
          banks in the London  interbank  market at or about  11.00 A.M. on that
          day for the relevant period;

     L    is the  percentage of eligible  liabilities  which (as a result of the
          requirements  of the Bank of England) Agent maintains as secured money
          with members of the London Discount  Market  Association or in certain
          marketable  or  callable  securities  approved by the Bank of England,
          which  percentage  shall (in the  absence of  evidence  that any other
          figure is appropriate) be conclusively presumed to be 5 per cent.;

     X    is the rate at which  secured GBP deposits may be placed by Agent with
          members of the London  Discount  Market  Association at or about 11.00
          A.M. on that day for the relevant  period or, if greater,  the rate at
          which GBP bills of exchange  (of a tenor equal to the  duration of the
          relevant period) eligible for rediscounting at the Bank of England can
          be discounted in the London  Discount Market at or about 11.00 A.M. on
          that day;

     S    is the percentage for Agent's eligible  liabilities  which the Bank of
          England requires Agent to place as a special deposit; and

     Z    is the  interest  rate per annum  allowed  by the Bank of  England  on
          special deposits.

                                    SCH. 5-1

     (b)  For the purposes of this Schedule:

          (i) "eligible  liabilities"  and "special  deposits" have the meanings
          given to them at the time of application of the formula by the Bank of
          England; and

          (ii) "relevant period" in relation to each Interest Period means:

          (A)  if it is 3 months or less, that Interest Period, or

          (B)  if it is more than 3 months, 3 months.

     (c)  In the application of the formula, B, Y, L, X, S and Z are included in
          the formula as figures and not as percentages,  e.g. if B=0.5% and Y =
          15%, BY is calculated as 0.5 x 15.

     (d)  The formula is applied on the first day of each relevant period.  Each
          amount is rounded up to the nearest one-sixteenth of one per cent.

     (e)  If Agent  determines that a change in circumstances  has rendered,  or
          will render, the formula inappropriate, Agent (after consultation with
          the  Lenders)  shall  notify  Borrower  of the  manner  in  which  the
          Mandatory  Liquid  Asset  Costs for such  Loans will  subsequently  be
          calculated.  The manner of calculation so notified by Agent shall,  in
          the absence of manifest error, be binding on Borrower.
