                  which are similar to the Leased Properties, which brand name,
                  as of the date of the Consent, is "AmeriSuites". Tenant shall
                  not change the brand of the Hotels without Landlord's prior
                  written consent, which consent shall not be unreasonably
                  withheld, delayed or conditioned, it being agreed that, it
                  shall be reasonable for Landlord to withhold its consent to a
                  brand name that is generally associated with lower prices than
                  the brand name under which the Hotels are then currently being

                  Property, have any assets or liabilities other than assets or
                  liabilities derived from or related to the Leased Property or

                  permitted herein, including, without limitation, the
                  operation, as a lessee or otherwise, of any property other
                  than the Leased Property;

                  b) have any subsidiaries;

                  c) amend, supplement or otherwise modify its governing
                  instruments with respect to (i) bankruptcy remoteness, (ii)
                  being a Single Purpose Entity or (iii) the Independent

                  jurisdiction in which such qualification is necessary to the
                  conduct of its business or to protect the validity and
                  enforceability of the Amended Lease and the Incidental
                  Documents, as the same may be amended or modified from time to
                  time;

                  e) fail to keep proper books of account and records in which
                  full, true and correct entries in accordance with GAAP shall
                  be made of all dealings and transactions in relation to its
                  business and activities;

                  f) fail to generally pay its debts as they become due;

                  g) take any action in furtherance of, or indicating its
                  consent to, approval of, or acquiescence in, any of the acts
                  set forth above.

         those, if any, contained in the applicable Exchange Option.

                  (ii) Landlord shall exercise such Put Option no later than the
         later of (x) March 31, 2002 and (y) the date that is ninety (90) days

         regardless of any dispute by Assignor or ShoLodge regarding whether
         such Event of Default or other event or circumstances has occurred.

                  (iii) Notwithstanding the foregoing, neither Assignor nor

         appropriately amended to eliminate from the Amended Lease the Sale
         Property (and the rent attributed thereto) being disposed of by the
         Landlord and to pro-rate the rents and other charges due under the
         Amended Lease as of the date of the closing of such sale with respect

         and Purchaser shall make appropriate adjustment on account of amounts
         contributed to, and expended from, the FF&E Reserve with respect to the

         of the Lease and (y) all Events of Default and Defaults resulting from
         violations or defaults under the Exchange Option Agreement(s).

         under the Lease, (B) the Landlord's obligation to forbear from
         exercising its rights and remedies in connection with such violations
         Section 22.11 pertaining to such Sale Property shall terminate, and (C)

thereof; (ii) any assignment or transfer in whole or in part of any of the
Guaranteed Obligations (as defined in the Guaranty) without notice to the

by the Tenant or any other guarantor of any other obligations under or arising
out of any of the foregoing or the extension or renewal thereof; (v) the
modification or amendment (whether material or otherwise) of any duty, agreement
or obligation of the Tenant or any other guarantor set forth in any of the
foregoing including, without limitations, the modifications contemplated by this
Agreement, the Options or in any other document executed in connection herewith
or the Amended Lease; (vi) the voluntary or involuntary sale or other

Assignor ever be obligated to contribute additional funds hereunder or under the
Guaranty to be added to or to replenish the Guaranty Deposit, including, without
limitation, upon any use of the Guaranty Deposit, any portion thereof or any
interest thereon to cure any default under the Amended Lease or any failure by
HPT, Landlord or any successor holder of the Guaranty Deposit to deliver the
Guaranty Deposit or any interest thereon as required herein. Nothing contained
in the foregoing shall diminish or reduce Sholodge's obligations under the
Supplemental Guaranty.

         (e) Sholodge, Landlord and HPT shall not amend or modify the Guaranty
without Prime's prior written consent; provided that the terms thereof as
modified hereby may be ratified and confirmed from time to time. Sholodge hereby
agreeing to execute and deliver such confirmations of the Guaranty as Landlord
may reasonably require in connection with the closings under the Exchange
Options and/or the Put Options. Further, Sholodge shall execute and deliver such
amendments to the Guaranty as Prime and Landlord shall request provided that no
such amendment modifies or diminishes the non-recourse nature of the Guaranty as
set forth in Section 10(d) above.

         (f) If, in connection with the assignment in whole or in part of the
Amended Lease, HPT and Landlord or any successor holder of the Guaranty Deposit
shall transfer the Guaranty Deposit to a someone having a Net Worth of not less
than ten (10) times the unapplied balance


                                      -17-
<PAGE>   18
thereof, Landlord and HPT or any such successor shall be relieved of all of
their obligations with respect to the Guaranty Deposit and interest thereon. If
such successor shall not satisfy the aforesaid Net Worth requirement, Landlord
and HPT shall, in a guaranty in form and substance reasonably satisfactory to
Prime, guaranty the payment of the Guaranty Deposit and interest thereon in
accordance with this Agreement. At the time of any such assignment, Landlord and
HPT shall cause such successor to acknowledge in writing to ShoLodge and
Assignor such successor's agreement to the continued applicability of the
provisions of Section 10(d).



         (g) Provided that no Event of Default shall have occurred and be
continuing, in lieu of the interest otherwise due under the Guaranty during the
Term, HPT shall credit the Tenant with interest on any unapplied balance of the
Guaranty Deposit at a rate of 11.11% per annum. Such interest shall be credited
against the rent and other charges due under the Lease in arrears and pro rated
with respect to any partial month.

         11. ADDITIONAL DEPOSIT. (a) Simultaneously with the execution and
delivery hereof, Prime has (i) deposited with Landlord the sum (the "ADDITIONAL
DEPOSIT") of Two Million Five Hundred Thousand Dollars ($2,500,000) as security
the payment and performance of each and every obligation of the Tenant to
Landlord under the Amended Lease and the Incidental Documents, whether now
existing or hereafter arising, and including, without limitation, the payment of
the full amount of the Rent payable under the Amended Lease and (ii) contributed
to Assignee the right to receive any interest due on the Additional Deposit
during the Term pursuant to the terms hereof. Landlord shall have no obligation
to hold the Additional Deposit in a segregated account and may commingle the
same with its general funds. Provided that no Event of Default shall have
occurred and be continuing, Landlord shall credit the Tenant with interest on
any unapplied balance of the Additional Deposit at a rate of 9% per annum. Such
interest shall be credited against the rent and other charges due under the
Amended Lease in arrears and pro rated with respect to any partial month. Upon
the earlier of the expiration of the Amended Lease and the payment and
performance of each and every obligation of the Tenant to Landlord and HPT under
the Lease and Incidental Documents and the termination of Prime's obligation to
keep the Additional Deposit with Landlord pursuant to Section 11(b) below,
provided no Event of Default shall have occurred and be continuing, Landlord
shall refund any unapplied balance of the Additional Deposit, together with any
accrued and unpaid (or uncredited) interest with respect thereto, to Prime. In
the event Landlord shall fail to refund any unapplied balance of the Additional
Deposit and accrued interest to Prime on the date due, Landlord shall thereafter
pay Prime interest thereon at the Overdue Rate until paid.

         (b) Provided that no (i) monetary Default, (ii) Default as to which
Notice thereof has been given to Tenant or (iii) Event of Default shall have
occurred and be continuing under the Amended Lease, (iv) Cash Flow for a period
of twelve (12) full consecutive Accounting Periods equals or exceeds Thirty-Four
Million Fifteen Thousand Dollars ($34,015,000) with respect to such period and
(v) Landlord shall receive a schedule evidencing the foregoing, in form and
substance reasonably satisfactory to Landlord prepared by a, so-called,
"Big-Five" accounting firm or such other certified public accountants as are
approved by Landlord (such approval not to be unreasonably withheld, delayed or
conditioned), the obligation of Prime to keep the


                                      -18-
<PAGE>   19
Additional Deposit with Landlord shall terminate ten (10) Business Days after
delivery to Landlord of the financial statements described in clause (v)
preceding, and Landlord shall, within ten (10) Business Days after the written
request of Prime, pay any unapplied balance of the Additional Deposit to Prime,
together with any accrued and unpaid interest thereon.

         (c) If, in connection with the assignment in whole or in part of the
Amended Lease, Landlord or any successor holder of the Additional Deposit shall
transfer the Additional Deposit to someone having a Net Worth of not less than
ten (10) times the unapplied balance thereof, Landlord or any such successor
shall be relieved of all of their obligations with respect to the Additional
Deposit and interest thereon. If such successor shall not satisfy the aforesaid
Net Worth requirement, Landlord shall, in a guaranty in form and substance
reasonably satisfactory to Prime, guaranty the payment of the Additional Deposit
and interest thereon in accordance with this Agreement.
