                                    EXHIBIT A
               MODIFICATIONS TO ASSIGNMENT OF MANAGEMENT AGREEMENT

The following modifications are made to the text of the Assignment that precedes
this Exhibit:

The Assignment is modified by adding a new Section 10 and a new Section 11 as
follows:

         "10.  Manager agrees that:

                    (a)     (i) any fees payable to Manager pursuant to the
               Management Agreement are and shall be subordinated in right of
               payment, to the extent and in the manner provided in this
               Assignment, to the prior payment in full of the Indebtedness (as
               defined in the Security Instrument), and (ii) the Management
               Agreement is and shall be subject and subordinate in all respects
               to the liens, terms, covenants and conditions of the Security
               Instrument and the other loan documents evidencing and securing
               the Loan and to all advances heretofore made or which may
               hereafter be made pursuant to the Security Instrument (including
               all sums advanced for the purposes of (x) protecting or further
               securing the lien of the Security Instrument, curing defaults by
               Guarantor under the Security Instrument or for any other purposes
               expressly permitted by the Security Instrument, or (y)
               constructing, renovating, repairing, furnishing, fixturing or
               equipping the Mortgaged Property);

                    (b)     if, by reason of its exercise of any other right or
               remedy under the Management Agreement, Manager acquires by right
               of subrogation or otherwise a lien on the Mortgaged Property
               which (but for this subsection) would be senior to the lien of
               the Security Instrument, then, in that event, such lien shall be
               subject and subordinate to the lien of the Security Instrument;

                    (c)     until Manager receives notice (or otherwise acquires
               actual knowledge) of an Event of Default, Manager shall be
               entitled to retain for its own account all payments made under or
               pursuant to the Management Agreement;

                    (d)     after Manager receives notice (or otherwise acquires
               actual knowledge) of an Event of Default, it will not accept any
               payment of fees under or pursuant to the Management Agreement
               without Lender's prior written consent;

                    (e)     if, after Manager receives notice (or otherwise
               acquires actual knowledge) of an Event of Default, Manager
               receives any payment of fees under the Management Agreement, or
               if Manager receives any other payment or distribution of any kind
               from Guarantor or from any

                                       A-1

               other person or entity in connection with the Management
               Agreement which Manager is not permitted by this Assignment to
               retain for its own account, such payment or other distribution
               will be received and held in trust for Lender and unless Lender
               otherwise notifies Manager, will be promptly remitted, in cash or
               readily available funds, to Lender, properly endorsed to Lender,
               to be applied to the principal of, interest on and other amounts
               due under the loan documents evidencing and securing the Loan in
               such order and in such manner as Lender shall determine in its
               sole and absolute discretion. Manager hereby irrevocably
               designates, makes, constitutes and appoints Lender (and all
               persons or entities designated by Lender) as Manager's true and
               lawful attorney in fact with power to endorse the name of Manager
               upon any checks representing payments referred to in this
               subsection;

                    (f)     Manager shall notify (telephonically, followed by
               written notice) Lender of Manager's receipt from any person or
               entity other than Guarantor or Borrower of a payment with respect
               to Guarantor's and Borrower's obligations under the loan
               documents evidencing and securing the Loan, promptly after
               Manager obtains knowledge of such payment; and

                    (g)     during the term of this Assignment Manager will not
               commence, or join with any other creditor in commencing any
               bankruptcy, reorganization, arrangement, insolvency or
               liquidation proceedings with respect to Guarantor, without
               Lender's prior written consent.

         11.   Guarantor agrees that after Guarantor receives notice (or
               otherwise has actual knowledge) of an Event of Default, it will
               not make any payment of fees under or pursuant to the Management
               Agreement without Lender's prior written consent."
