                                        Name:   Patrick Carroll
                                        Title:  Executive Vice President






                                    Exhibit 1
                                    ---------


                     Montgomery Limited Partners Supplement

               As a result of the contribution of the interests in Barnhech
Montgomery Limited Partnership ("Montgomery") on October 28, 2004, the General
Partner pursuant to Section 4.2.A and Sections 14.1.B(2) and 14.1.B(3) of this
Agreement has authorized the issuance of Partnership Units to those former
limited partners of Montgomery (the "Montgomery Limited Partners") electing to
contribute all of their interests to the Partnership. Each Montgomery Limited
Partner shall receive the number of Partnership Units specified below. For
purposes of applying the terms and conditions of the Agreement, each Montgomery
Limited Partner shall be a Partner of the Partnership with the rights and
obligations of Additional Limited Partners.

               Notwithstanding Section 5.1.A of the Agreement, each Montgomery
Limited Partner shall be entitled to receive distributions with respect to each
Partnership Unit equal to the cash dividend payable with respect to each share
of REIT Shares, determined at the time of each quarterly distribution beginning
with the distribution payable to shareholders of record of LXP in November,
2004.

               Partnership taxable income shall be specially allocated to each
Montgomery Limited Partner in an amount equal to, but not in excess of, the cash
distributed to each such Montgomery Limited Partner; provided, however, that
each such Montgomery Limited Partner shall be allocated taxable income as
otherwise required in Exhibit B and C of the Partnership Agreement.

               For purposes of Section 8.4 of the Partnership Agreement,
beginning on May 1, 2006, and on each August 1st, November 1st, February 1st,
and May 1st thereafter (each a "Notice Date"), each Montgomery Limited Partner
shall have the right (the "Montgomery Limited Partner Redemption Right") to
require the Partnership to redeem on a Specified Redemption Date the Partnership
Units held by such Montgomery Limited Partner for the Redemption Amount to be
delivered by the Partnership; provided, however, that each Montgomery Limited
Partner must convert a number of Partnership Units equal to at least the lesser
of (i) 1,000 Partnership Units, or (ii) all of the Partnership Units held by
such partner. The Montgomery Limited Partner Redemption Right shall be exercised
pursuant to a Notice of Redemption (substantially in the form of Exhibits D-1
through D-4) delivered to the General Partner and LXP on a Notice Date by the
Montgomery Limited Partner who is exercising its Montgomery Limited Partner
Redemption Right (the "Montgomery Redeeming Partner"). The Montgomery Redeeming
Partner shall have no right, with respect to any Partnership Units so redeemed,
to receive any distributions paid after the Specified Redemption Date. The
Partnership covenants to cause the registration of any REIT Shares issued in
connection with a redemption in such a manner as is required so that the REIT
Shares issued in


                                   Exhibit 1-1




connection with such redemption are freely transferable. The Assignee of any
Montgomery Limited Partner may exercise the redemption rights of such Montgomery
Limited Partner, and such Montgomery Limited Partner shall be deemed to have
assigned such rights to such Assignee and shall be bound by the exercise of such
rights by such Assignee. In connection with any exercise of such rights by such
Assignee on behalf of such Montgomery Limited Partner, the Redemption Amount
shall be delivered by the Partnership directly to such Assignee and not to such
Montgomery Limited Partner.

               The Partnership Units held by a Montgomery Limited Partner shall
be subject to redemption by the Partnership if otherwise required by the terms
of the Partnership Agreement.

               LXP agrees to enter into a Guaranty Agreement with the
Partnership on the date the Montgomery Limited Partner are admitted to the
Partnership, on terms reasonably satisfactory to LXP and the Partnership,
pursuant to which LXP shall guaranty the obligations of the Partnership to pay
the Redemption Amount on the Specified Redemption Date.

               Each of the Montgomery Limited Partners, LXP, the Partnership and
the General Partner shall treat the transaction between LXP and each Montgomery
Limited Partner as a sale of the Montgomery Redeeming Partner's Partnership
Units to LXP or the General Partner, as the case may be, for federal income tax
purposes. Each Montgomery Limited Partner agrees to execute such documents as
the Partnership may reasonably require in connection with the issuance of REIT
Shares upon exercise of its Redemption Right.
