<FN>
<F1> Mid-Atlantic Realty Trust (MART) is in the specialized real estate industry
     for which the current/noncurrent  distinction is deemed in practice to have
     little or no relevance. Therefore, MART prepares unclassifed balance sheets
     which do not report current assets or current liabilities.
