Gentlemen:

                  Reference is made to (i) the Purchase  Agreement  and (ii) the
purchase money note of even date herewith made by the  undersigned in the amount
of $30,210,000 (the "Note") and the mortgages and/or deeds of trust and/or deeds
to  secure  debt  securing  the  Note   (individually  and   collectively,   the
"Mortgage").

                  We hereby agree that until such time as all amounts  evidenced
and secured by the Note and the Mortgage have been paid in full we shall not:

                  (i)  transfer,  or agree to transfer  (or suffer or permit the
         transfer or agreement to transfer),  in any manner,  either voluntarily
         or involuntarily,  by operation of law or otherwise, all or any portion
         of  the  property  located  in  Henrico  County,   Virginia  heretofore
         transferred  to us by a deed from you  dated  September  20,  1999 (the
         "Virginia  Property"),  without,  in any such case,  your prior written
         consent,  which  shall not be  unreasonably  withheld  in the case of a
         transfer to any affiliate or  subsidiary  wholly owned by Apple Suites,
         Inc.; or

                  (ii)  encumber,  or agree to encumber,  in any manner,  either
         voluntarily or involuntarily,  by operation of law or otherwise, all or
         any portion of any Virginia Property, or any interest or rights therein
         without,  in any such case, your prior written consent. As used in this
         clause,  "encumber" shall include,  without limitation,  the placing or
         permitting  the placing of any mortgage,  deed of trust,  assignment of
         rents or other security device. (It is understood that you may grant or
         deny your  consent  under  this  clause and the  immediately  preceding
         clause in your sole discretion).



                  Notwithstanding  the foregoing,  it is understood that neither
the lease to Apple Suites Management, Inc. from us, dated September 20, 1999 nor
the Deed of Trust, Assignment of Leases and Rents and Security Agreement made by
us and Apple Suites Management,  Inc. for your benefit dated September 20, 1999,
shall constitute a violation of the foregoing restrictions.

                                                Very truly yours,
