(1)  Funds From Operations is defined by the National Association of Real Estate
     Investment Trusts as net income or loss excluding gains or losses from debt
     restructuring and sales of property plus depreciation and amortization, and
     after adjustments for minority interest, unconsolidated partnerships and
     joint ventures (adjustments for minority interest, unconsolidated
     partnerships and joint ventures are calculated to reflect Funds From
     Operations on same basis). Funds From Operations does not represent cash
     flow from operations as defined by generally accepted accounting
     principles, should not be considered as an alternative to net income as an
     indicator of the Partnership's operating performance, and is not indicative
     of cash available to fund all cash flow needs.
