         For purposes of administering the LTIP, during the 1999, 2000, 2001
three-year cycle, (i) all LTIP awards shall be paid in the form of restricted
shares; (ii) the number of restricted shares shall be determined by dividing the
dollar value of the Maximum LTIP Value, $102,000, by the closing price on April
19, 1999 or the first trading day thereafter, on the New York Stock Exchange (or
such other market on which the Company's stock trades if it is not listed on the
New York Stock Exchange); (iii) the restricted shares, among other things, shall
be subject to a risk of forfeiture if and to the extent that the performance
criteria set forth in this Exhibit A with respect to the 1999, 2000, 2001 Cycle
Years are not met; (iv) if actual cumulative Net Asset Value Per Share for the
three-year period ending December 31, 2001, does not equal or exceed Threshold
LTIP Net Asset Value Per Share for such period, all restricted shares shall be
forfeited, and no LTIP bonus will have been earned; (v) if actual cumulative Net
Asset Value Per Share for the three year period ending December 31, 2001,
exceeds Threshold LTIP Net Asset Value Per Share, but is less than Target LTIP
Net Asset Value Per Share, for such period, or exceeds Target LTIP Net Asset
Value Per Share, but is less than Maximum LTIP Net Asset Value Per Share, for
such period, the percentage of the LTIP restricted shares as to which the risk
of forfeiture shall lapse shall be proportionately increased above the Threshold
bonus amount or the Target Bonus amount, as the case may be; and (vi) if
cumulative Net Asset Value Per Share for the three-year period ending December
31, 2001 equals or exceeds Maximum LTIP Net Asset Value Per Share for such
period, the risk of forfeiture shall lapse as to all restricted shares, but no
additional shares will be issuable under the LTIP regardless of the amount by
which actual cumulative net asset value per share for the three years ending
December 31, 2001 exceeds such Maximum LTIP Net Asset Value Per Share.
