                           GLOSSARY


     The following terms are defined in Article III of the

will govern all relations between the Limited Partners and the

understanding the way such terms are used in the Partnership
Agreement and in this Prospectus, certain additional and somewhat
less technical definitions are set forth below:

Acquisition Fees) related to the selection and acquisition of
properties, whether or not acquired, including but not limited to
legal fees and expenses, travel and communications expenses,

not acquired, accounting fees and expenses, title insurance and
miscellaneous expenses.

     "Acquisition Fees" means the total of all fees and
commissions paid by any party in connection with the purchase or
development of a property by the Partnership.  Included in the
computation of such fees or commissions shall be any real estate

management fee, or any fee of a similar nature, however
designated, except that Acquisition Fees shall not include
development fees paid to non-affiliated parties in connection
with actual development of a property after the acquisition
thereof by the Partnership.  As used in the preceding sentence,
