Mendik/FW LLC of the Major Partner Agreement with respect to Two Penn Plaza
Associates, in exchange for the number of Units set forth on Schedule A with
respect to such transfers, in accordance with the terms of such Major Partner
Agreement as the same may be hereafter amended, with the consent of Vornado (not
to be unreasonably withheld or delayed). Such assignment of the Major Partner
Agreement would provide that any refunds of real estate taxes received with
respect to Two Penn Plaza for periods prior to the Closing Date would be
retained by Mendik/FW LLC.

     2. The Mendik Partnership L.P.'s general partnership interest in Two Penn
Plaza Associates would be transferred to a limited liability company ("LLC")

LLC.

     2. The interests of all of the partners of M/F Associates, M/F Eleven

          a. The Major Partner interests in 1740 Broadway Associates would be
     purchased by a wholly owned LLC of the Operating Partnership ("OP Sub-

     with respect to 1740 Broadway Associates, for cash (in the amount set forth
     on Schedule A annexed hereto and made a part hereof with respect to such
     transfers) in accordance with the terms of such Major Partner Agreement as
     the same may be hereafter amended, with the consent of Vornado (not to be
     unreasonably withheld or delayed). Such assignment of the Major Partner

     retained by Mendik/FW LLC.

          b. The interests of the partners in 1740 Broadway Investment Company
     other than the interests of Mr. Mendik, MIL Equities and 1740 Corp., would
     be purchased by the Operating Partnership for cash in the amount set forth
     on Schedule A with respect to such transfer. The interests of Mr. Mendik,
     MIL Equities and Mendik 1740 Corp. in 1740 Broadway Investment Company

     set forth on Schedule A with respect to such transfers. Upon such purchase

     Operating Partnership would be the limited partners of 1740 Broadway
     Associates.

          d. If less than all of the partners in 1740 Broadway Investment
     Company consent to the transfers of their interests, then 1740 Broadway
     Investment Company would transfer its interest as a partner in 1740
     Broadway Associates, L.P. to the Operating Partnership for cash in the
     amount set forth on Schedule A with respect to such transfer.

   3

all of the interests in 1740 Broadway Associates as contemplated by Section 5.12
of the Agreement, then the Vornado 1740 Sub would transfer all of such interests
to the Operating Partnership or to OP Sub-1740, as Vornado shall elect. As a
result, 1740 Broadway Associates would be wholly owned by the Operating
Partnership and/or OP Sub-1740.

     The assignment of the Major Partner Agreement from Mendik/FW LLC to Vornado
in accordance with Section 5.12 of the Agreement would provide that any refunds

Operating Partnership would be the sole member of 866 U.N. Plaza Associates LLC.

Major Partner interests in B&B would be purchased by a wholly owned LLC of the
Operating Partnership ("OP Sub-B&B"), as the assignee of Mendik/FW LLC of the

on Schedule A with respect to such transfers) in accordance with the terms of
such Major Partner Agreement as the same may be hereafter amended, with the
consent of Vornado (not to be unreasonably withheld or delayed). Immediately
after such acquisition, OP Sub-B&B would transfer its interest as a limited
partner in B&B to the Operating Partnership. Such assignment of the Major
Partner Agreement would provide that any refunds of real estate taxes received
with respect to Two Park Avenue for periods prior to the Closing Date would be
retained by Mendik/FW LLC.

     b. If the Closing Date shall be after the Outside Date and Mendik/FW LLC
shall have acquired the Major Partner interests in B&B for cash (in the amount
set forth on Schedule A with respect to such transfers), which cash shall have
been loaned to Mendik/FW LLC by the Vornado 1740 Sub pursuant to the B&B Loan
(as defined in Section 5.12 of the Agreement), then OP Sub-B&B shall acquire
such interests directly from Mendik/FW LLC pursuant to the Contribution
Agreement described in Section 1.1(f) of the Agreement. Immediately after such
acquisition, Op Sub-B&B would transfer its interest as a limited partner in B&B
to the Operating Partnership. Such Contribution Agreement relating to the
transfer of the Major Partner interest in B&B would provide that any refunds of
real estate taxes received with respect to Two Park Avenue for periods prior to

(including the right to receive 100% of the priority payments payable to The
Mendik Partnership, L.P., but excluding any rights or obligations of The Mendik
Partnership, L.P. as managing general partner) would be converted to a limited
partnership interest. The Mendik Partnership L.P. would retain a 1% general
partnership interest and would remain as managing partner of M 330 Associates.
The conversion of The Mendik Partnership L.P.'s interest would expressly provide
that the converted interest excludes any rights or obligations of The Mendik
Partnership L.P. as managing general partner.

     2. At the closing, The Mendik Partnership, L.P.'s interest as a limited
partner in M 330 Associates would be transferred to the Operating Partnership in

G.   570 Lexington

     1. The interests of the partners in 570 Lexington Investors would be
transferred to the Operating Partnership in exchange for the number of Units set
forth on Schedule A with respect to such transfers. Upon such purchase and
transfers, 570 Lexington Investors would dissolve by operation of law. The
outstanding principal balance [together with accrued interest thereon] of the
promissory note, dated as of October 1, 1996, from 570 Lexington Investors to
Mendik Realty, given with respect to the capital contributions to 570 Lexington
Associates made by Mendik Realty after October 1, 1996, on behalf of and as a
loan to 570 Lexington Investors, will be paid by the Operating Partnership
simultaneously with the consummation of the foregoing transfers. The outstanding
principal balance of such promissory note, as of March 1, 1997, is $280,000.

     2. Mendik 570 Corp. would transfer its general partnership interest in 570

Company, L.P.) as special limited partner would be transferred to the Operating
Partnership in exchange for the number of Units set forth on Schedule A with
respect to such transfer. As a result, the general partners of 570 Lexington
Associates, L.P. would be Quantum 570 Lexington L.P., OP Sub-570 and the limited
partner and special limited partner would be the Operating Partnership.

     After giving effect to all of the foregoing transfers, the Operating
Partnership or a subsidiary of the Operating Partnership would have acquired the
interests of the Partners in exchange for a combination of cash and Units as set
forth on Schedule A, all pursuant to the Partner Interest Contribution
Agreements. The number of Units issued to each class of Partners in Eleven Penn
Plaza, 330 Madison Avenue and 866 U.N. Plaza, as set forth on Schedule A, may
increase based upon adjustments made with respect to "Net Other Assets" as more
particularly described in the respective Partner Interest Contribution
Agreements affecting the contribution of interests in such properties. 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. Plaza
Associates) of 866 U.N. Plaza Associates exceeds $9,250,000 as of the Closing
Date.

     In the event that any of the foregoing transfers cannot be consummated as a
result of the failure to obtain any necessary consents in connection with the


                                      -5-
   6

transfers contemplated hereby, the Mendik Group, Vornado and the Operating
Partnership will use commercially reasonable efforts to restructure the
transfers of interests to the Operating Partnership so as to effect a result
similar to the structure contemplated by this Appendix A, provided that the same
shall not change in any material respect the rights and obligations of the
parties from those otherwise contemplated in this Agreement.
