The number of Units issued to Mendik/FW LLC in the recapitalization of the Operating Partnership pursuant to Section 1.2 of this Agreement shall be reduced by an amount equal to the quotient of (x) the sum of (i) the amount by which "Net Other Assets" (as defined in the Partner Interest Contribution Agreements with respect to Eleven Penn Plaza Company) of Eleven Penn Plaza Company exceeds $0 as of the Closing Date, and (ii) the amount by which "Net Other Assets" (as defined in the Partner Interest Contribution Agreement with respect to 866 U.N.
