in the issue price and interest accrued prior to the issue date of such
Additional Notes, provided that such Additional Notes constitute part of the
same issue as the Notes for U.S. federal income tax purposes. Any Additional
Notes shall be treated as a single series with the Notes under the Indenture and
shall have the same terms as to status, redemption, repurchase, exchange and
otherwise as the Notes. For clarity, the limitations in this Section 2.02,
including the limitation on the aggregate principal amount of the Notes which
may be authenticated and delivered under the Indenture, shall not apply or be
construed to apply to any series of Securities, other than the Notes, that may

Notes shall be issuable initially in the form of one or more global Securities
registered in the name of The Depository Trust Company's nominee, and shall be

York (the "Depositary"). The Notes may be surrendered for registration of

Maturity of the principal of the Notes shall be January 15, 2027.

                  Section 2.05. Interest. The Notes shall bear interest at the
rate of 5.45% per annum from, and including, January 29, 2007 or from the most
recent Interest Payment Date to which interest has been paid or provided for, as
the case may be, and shall be payable semi-annually in arrears on January 15 and
July 15 of each year (each, an "Interest Payment Date"), commencing on July 15,
2007, until the principal thereof is paid or duly made available for payment, to
the Persons in whose names such Notes are registered at the close of business on
the January 1 or July 1 (whether or not a Business Day) immediately preceding
the applicable Interest Payment Date (each, a "Regular Record Date"). Interest
payable on each Interest Payment Date shall equal the amount of interest accrued
for the period commencing on and including the immediately preceding Interest
Payment Date in respect of which interest has been paid (or commencing on and
including January 29, 2007, if no interest has been paid) and ending on and
including the day preceding such Interest Payment Date. Interest on the Notes
shall be computed on the basis of a 360-day year consisting of twelve 30-day
months.

                  Notwithstanding anything to the contrary contained herein, if
the Issuer shall redeem the Notes in accordance with the provisions of Section
2.07 hereof, or if a Holder shall surrender a Note for repurchase by the Issuer
in accordance with the provisions of 2.08 or 2.09 hereof, subject to the next
succeeding sentence, accrued and unpaid interest (including Additional Interest,
if any) shall be payable to the Holder that shall have surrendered such Note for
redemption or repurchase, as the case may be. However, if the Redemption Date or
Optional Repurchase Date or Change of Control Purchase Date, as the case may be,
for a Note falls after the Regular Record Date and on or prior to the related
Interest Payment Date, accrued and


                                      -8-



unpaid interest (including Additional Interest, if any) due on such Interest
Payment Date shall be payable instead to the Person in whose name such Note is
registered at the close of business on the related Regular Record Date.

                  Section 2.06. Place of Payment. The principal of and the
interest on the Notes shall be payable at the office or agency of the Issuer or
the Parent Guarantor (including the Trustee) maintained for such purpose in the
Borough of Manhattan, The City of New York in the in the manner specified in the
Indenture.

                  Section 2.07. Redemption. The Issuer shall not have the right
to redeem any Notes prior to January 20, 2012, except to preserve the Parent
Guarantor's status as a real estate investment trust for U.S. federal income tax
purposes. If, at any time, the Issuer determines it is necessary to redeem the
Notes in order to preserve the Parent Guarantor's status as a real estate
investment trust for U.S. federal income tax purposes, the Issuer may, upon not
less than 30 nor more than 60 days' prior written notice by mail to the Holders
of the Notes, redeem the Notes in whole or in part, for cash equal to 100% of
the principal amount of the Notes to be redeemed plus accrued and unpaid
interest (including Additional Interest, if any) to, but not including, the
Redemption Date. In such case, the Issuer shall provide the Trustee with an
Officers' Certificate evidencing that the Board of Trustees of the Parent
Guarantor has, in good faith, made the determination that it is necessary to
redeem the Notes in order to preserve the Parent Guarantor's status as a real
estate investment trust for U.S. federal income tax purposes.

                  The Issuer shall have the right to redeem the Notes, in whole
or in part at any time or from time to time, on or after January 20, 2012 upon
not less than 30 nor more than 60 days' prior written notice by mail to the
Holders of the Notes, at a redemption price ("Redemption Price") for cash equal
to 100% of the principal amount of the Notes to be redeemed plus accrued and
unpaid interest (and Additional Interest, if any) to, but not including, the
Redemption Date. If less than all the Notes are to be redeemed, the Trustee
shall select the Notes to be redeemed (in principal amounts of $1,000 and
integral multiples thereof) on a pro rata basis or by such other method the
Trustee considers fair and appropriate. The Trustee shall make the selection at
least 30 days but not more than 60 days before the Redemption Date from
Outstanding Notes not previously called for redemption. Notes and portions of
the principal amount thereof selected for redemption shall be in integral
multiples of $1,000. The Trustee shall notify the Issuer promptly of the Notes
or portions of the principal amount thereof to be redeemed. If the Trustee
selects a portion of a Note for partial redemption and a Holder exchanges a
portion of the same Note in accordance with the provisions of Section 2.11
hereof before termination of the exchange right with respect to the portion of
the Note so selected, the exchanged portion of such Note shall be deemed to be
from the portion selected for redemption. Notes that have been exchanged
pursuant to Section 2.11 hereof during a selection of Notes to be redeemed shall
be treated by the Trustee as Outstanding for the purpose of such selection.

                  In the event of any redemption of the Notes in part, the
Issuer shall not be required to: (i) issue or register the transfer or exchange
of any Note pursuant to Section 305 of the Original Indenture during a period
beginning at the opening of business 15 days before any selection of Notes for
redemption and ending at the close of business on the earliest date on which the
relevant notice of redemption is deemed to have been given to all Holders of
Notes to be so redeemed, or (ii) register the transfer or exchange pursuant to
Section 305 of the Original


                                      -9-



Indenture of any Note so selected for redemption, in whole or in part, except
the unredeemed portion of any Note being redeemed in part.

                  In addition to those matters set forth in Section 1104 of the
Original Indenture, a notice of redemption sent to the Holders of Notes to be
redeemed in accordance with the provisions of the two preceding paragraphs shall
state:

                                    (a) the name and address of the Trustee, the
Paying Agent and Exchange Agent;

                                    (b) the then current Exchange Rate;

                                    (c) that Notes called for redemption may be
exchanged pursuant to Section 2.11 hereof at any time prior to the close of
business on the second Business Day immediately preceding the Redemption Date;
and

                                    (d) that Holders who wish to exchange Notes
pursuant to Section 305 of the Original Indenture must comply with the
procedures relating thereto specified in Section 2.13 hereof.

                  Section 2.08. Repurchase Rights. A Holder of Notes shall have
the right to require the Issuer to repurchase such Holder's Notes, in whole or
in part (in principal amounts of $1,000 or an integral multiple thereof), on
each of January 20, 2012, January 15, 2017 and January 15, 2022 (each, an
"Optional Repurchase Date") for cash equal to 100% of the principal amount of
the Notes to be repurchased plus accrued and unpaid interest (including
Additional Interest, if any,) to, but not including, the Optional Repurchase
Date (such amount, the "Optional Repurchase Price"), subject to satisfaction by
or on behalf of the Holder of the requirements set forth below.

                  On or before the 20th Business Day prior to each Optional
Repurchase Date, the Issuer shall provide a written notice by first-class mail

required by applicable law). The notice shall include a form of Optional
Repurchase Notice to be completed by the Holder and shall state:

                                    (f) that the Optional Repurchase Price for
any Note as to which an Optional Repurchase Notice has been duly given shall be
paid within two Business Days after the later of the Optional Repurchase Date or
the time at which such Notes are surrendered for repurchase;

                                    (g) that, unless the Issuer defaults in
making payment of the Optional Repurchase Price, interest on Notes surrendered
for repurchase shall cease to accrue on and after the Optional Repurchase Date;

                                    (h) that Notes in respect of which an
Optional Repurchase Notice is provided by a Holder shall not be exchangeable in
accordance with their terms and pursuant to Section 2.11 hereof even if
otherwise exchangeable unless such Holder validly withdraws such Optional
Repurchase Notice in accordance with the provisions of this Section 2.08; and

                                    (i) the CUSIP number of the Notes.

Businesswire, Dow Jones & Company, Inc. or Bloomberg Business News containing

newspaper of general circulation in The City of New York, or through such other
public medium as the Issuer shall deem appropriate at such time. In addition,
the Parent Guarantor shall post any such press release on its website or

                  A Holder may exercise its rights specified in this Section
2.08 by delivery of a written notice of repurchase (an "Optional Repurchase
Notice") to the Paying Agent during the period beginning at any time from the
opening of business on the date that is 20 Business Days prior to the applicable
Optional Repurchase Date until the close of business on the second Business Day
prior to such Optional Repurchase Date, stating:

the Notes to be repurchased, in integral multiples of $1,000, provided that the
remaining principal amount of Notes is in an authorized denomination; and

                                    (c) that such Notes shall be repurchased by
the Issuer pursuant to the applicable provisions hereof and the Notes.

                  The Paying Agent shall promptly notify the Issuer and the
Parent Guarantor in writing of the receipt by it of any Optional Repurchase
Notice.

                  Book-entry transfer of Notes in book-entry form in compliance
with appropriate procedures of the Depositary or delivery of Notes in
certificated form, together with all necessary endorsements, to the Paying Agent
at the offices of the Paying Agent shall be a condition to the receipt by the
Holder of the Optional Repurchase Price therefor. Holders electing to require
the Issuer to repurchase Notes must effect such transfer or delivery to the

                                      -11-


Paying Agent on or prior to the Optional Repurchase Date to receive payment of
the Optional Repurchase Price on or within two Business Days after the Optional
Repurchase Date. The Issuer shall pay the Optional Repurchase Price within two
Business Days after the later of the Optional Repurchase Date or the time of
such transfer or delivery of the Notes.

                  An Optional Repurchase Notice may be withdrawn in whole or in
part by a Holder by means of a written notice of withdrawal delivered to the
office of the Paying Agent prior to the close of business on the second Business

                                    (a) the Holder's name;

                                    (b) the principal amount of Notes in respect

withdrawal are in certificated form, the certificate number(s) of all Notes
subject to the notice of withdrawal; and

                                    (d) the principal amount of Notes, if any,
that remains subject to the Optional Repurchase Notice, which must be an
integral multiple of $1,000.

                  If Notes subject to the notice of withdrawal are in book-entry
form, the above notices must also comply with the applicable procedures of the
Depositary.

                  On or before 10:00 a.m. (New York City time) on the Optional
Repurchase Date, the Issuer shall deposit with the Paying Agent (or if the
Issuer or an Affiliate of the Issuer is acting as the Paying Agent, shall
segregate and hold in trust) money sufficient to pay the aggregate Optional
Repurchase Price of the Notes to be purchased pursuant to this Section 2.08. If
the Paying Agent holds, in accordance with the terms of the Indenture, money
sufficient to pay the Optional Repurchase Price of such Notes on the Optional
Repurchase Date, then on and after such date, such Notes shall cease to be
Outstanding and interest on such Notes shall cease to accrue, and all rights of
the Holder of such Notes shall terminate (other than the right to receive the
Optional Repurchase Price after delivery or transfer of the Notes). Such shall
be the case whether or not book-entry transfer of the Notes in book-entry form
is made and whether or not Notes in certificated form, together with the
necessary endorsements, are delivered to the Paying Agent.

                  Notwithstanding the foregoing, no Notes may be purchased by
the Issuer in accordance with the provisions of this Section 2.08 if there has
occurred and is continuing an Event of Default with respect to the Notes (other
than a default in the payment of the Optional Repurchase Price).

                  To the extent legally required in connection with a repurchase
of Notes, the Issuer shall comply with the provisions of Rule 13e-4 and other
tender offer rules under the Exchange Act then applicable, if any, and shall
file a Schedule TO or any other schedule required under the Exchange Act.


                                      -12-



                  The Issuer may arrange for a third party to purchase Notes for
which the Issuer has received a valid Optional Repurchase Notice that has not
been properly withdrawn, in the manner and otherwise in compliance with the
requirements set forth herein and in the Notes. If a third party purchases any
Notes under such circumstances, then interest shall continue to accrue on the
Notes and such Notes shall continue to be Outstanding after the Optional
Repurchase Date for all purposes of the Indenture and, subject to compliance
with applicable law, shall be fungible with all other Notes then Outstanding.

                  Section 2.09. Repurchase at Option of Holders upon a Change of
Control. If a Change of Control occurs at any time prior to January 20, 2012, a
Holder of Notes shall have the right to require the Issuer to repurchase such
Holder's Notes, in whole or in part (in principal amounts of $1,000 or an
integral multiple thereof) for cash equal to 100% of the principal amount of the
Notes to be repurchased, plus accrued and unpaid interest (including Additional
Interest, if any) to, but not including, the Change of Control Purchase Date
(such amount, the "Change of Control Purchase Price"), subject to satisfaction
by or on behalf of the Holder of the requirements set forth below. If a Change
of Control occurs on or after January 20, 2012, Holders of Notes shall not have
any right to require the Issuer to repurchase their Notes, except in accordance
with Section 2.08.

                  Within 20 days after the occurrence of a Change of Control,
the Issuer shall mail a written notice of Change of Control and of the
repurchase right arising as a result of the Change of Control (the "Issuer
Notice") by first-class mail to the Trustee, any Paying Agent and to each Holder
(and to beneficial owners as required by applicable law). The notice shall
include a form of Change of Control Purchase Notice to be completed by the
Holder and shall state:

                                    (a) the events causing a Change of Control
and the date of such Change of Control;

                                    (b) the date by which the Change of Control
Purchase Notice must be delivered to the Paying Agent;

of Control Purchase Notice is provided by a Holder shall not be exchangeable
pursuant to Section 2.11 of the First Supplemental Indenture unless such Holder
validly withdraws such Change of Control Purchase Notice in accordance with the
provisions of this Section 2.09;

                                    (g) that Notes must be surrendered to the
Paying Agent to collect payment of the Change of Control Purchase Price and the
procedures that Holders must follow to require the Company to repurchase their
Notes;


                                      -13-



                                    (h) that the Change of Control Purchase
Price for any Note as to which a Change of Control Purchase Notice has been duly
given shall be paid within two Business Days after the later of the Change of
Control Purchase Date or the time at which such Notes are surrendered for
repurchase;

                                    (i) that, unless the Issuer defaults in
making payment of the Change of Control Purchase Price, interest on Notes
surrendered for repurchase shall cease to accrue on and after the Change of
Control Purchase Date; and

                                    (j) the CUSIP number of the Notes.

Businesswire, Dow Jones & Company, Inc. or Bloomberg Business News announcing
the occurrence of such Change of Control or publish such information in a
newspaper of general circulation in The City of New York, or through such other
public medium as the Issuer shall deem appropriate at such time. In addition,
the Parent Guarantor shall post any such press release on its website or
disseminate it through any other appropriate medium.

                  A Holder may exercise its rights specified in this Section
2.09 upon delivery of a written notice of such Holder's exercise of its
repurchase right (a "Change of Control Purchase Notice") to the Paying Agent at
any time prior to the close of business on the third Business Day prior to the
Change of Control Purchase Date, stating:

                                    (a) if such Notes are in certificated form,

                                    (c) that such Note shall be repurchased
pursuant to the applicable provisions hereof and of the Notes.

                  The Paying Agent shall promptly notify the Issuer and the

                                      -14-



                  A Change of Control Purchase Notice may be withdrawn in whole
or in part by a Holder by means of a written notice of withdrawal delivered to
the office of the Paying Agent prior to the close of business on the third
Business Day prior to the Change of Control Purchase Date specifying:

                                    (a) the Holder's name;

                                    (b) if the Notes subject to the notice of

that remains subject to the Change of Control Purchase Notice, which must be an
integral multiple of $1,000.

                  If Notes subject to the notice of withdrawal are in book-entry

Depositary.

                  On or before 10:00 a.m. (New York City time) on the Change of
Control Purchase Date, the Issuer shall deposit with the Paying Agent (or if the
Issuer or an Affiliate of the Issuer is acting as the Paying Agent, shall
segregate and hold in trust) money sufficient to pay the aggregate Change of
Control Purchase Price of the Notes to be purchased pursuant to this Section
2.09. If the Paying Agent holds, in accordance with the terms of the Indenture,
money sufficient to pay the Change of Control Purchase Price of such Notes on
the Change of Control Purchase Date, then, on and after such date, such Notes
shall cease to be Outstanding and interest on such Notes shall cease to accrue

Notes in book-entry form is made and whether or not Notes in certificated form,
together with the necessary endorsements, are delivered to the Paying Agent.

                  Notwithstanding the foregoing, no Notes may be repurchased by
the Issuer in accordance with the provisions of this Section 2.09 if there has
occurred and is continuing an Event of Default with respect to the Notes (other
than a default in the payment of the Change of Control Purchase Price).

                  To the extent legally required in connection with a repurchase
of Notes, the Issuer shall comply with the provisions of Rule 13e-4 and other
tender offer rules under the Exchange Act then applicable, if any, and will file
a Schedule TO or any other schedule required under the Exchange Act.

                  The Issuer may arrange for a third party to purchase Notes for
which the Issuer has received a valid Change of Control Purchase Notice that has
not been properly withdrawn, in the manner and otherwise in compliance with the
requirements set forth herein and in the Notes. If a third party purchases any
Notes under such circumstances, then interest shall continue to accrue on the
Notes and such Notes shall continue to be Outstanding after the Change of
Control


                                      -15-



Purchase Date for all purposes of the Indenture and, subject to compliance with
applicable law, shall be fungible with all other Notes then Outstanding.

                  Section 2.10. Adjustment to Exchange Rate Upon Certain Change
of Control Transactions. If a Change of Control occurs prior to January 20, 2012
as a result of a transaction or event described in clauses (1) or (2) of the
definition of Change of Control and a Holder elects to exchange its Notes in
connection with such Change of Control pursuant to Section 2.11(d), the Issuer
shall increase the applicable Exchange Rate for such Notes surrendered for
exchange by a number of additional Lexington Common Shares (the "Additional
Shares") as specified below. An exchange of Notes shall be deemed for these
purposes to be "in connection with" such a Change of Control if the notice of
exchange of the Notes is received by the Exchange Agent on any date from and
including the date that is the Effective Date (as defined below) of such Change
of Control up to and including the 30th Business Day following the Effective
Date of such Change of Control or, if applicable, the related Change of Control
Repurchase Date.

                  The number of Additional Shares shall be determined by
reference to the table below and is based on the date on which such Change of
Control transaction becomes effective (the "Effective Date") and the price (the
"Share Price") paid per Lexington Common Share in such Change of Control
transaction. If holders of Lexington Common Shares receive only cash in a Change
of Control transaction described in clause (1) of the definition of such term,
the Share Price shall be the cash amount paid per Lexington Common Share. In all
other cases, the Share Price shall be the average of the Closing Sale Prices of
Lexington Common Shares on the 10 consecutive Trading Days up to but excluding
the Effective Date.

                  The Share Prices set forth in the first row of the table
(i.e., the column headers) shall be adjusted as of any date on which the
Exchange Rate of the Notes is adjusted. The adjusted Share Prices shall equal
the Share Prices applicable immediately prior to such adjustment multiplied by a
fraction, the numerator of which is the Exchange Rate immediately prior to the
adjustment giving rise to the Share Price adjustment and the denominator of
which is the Exchange Rate as so adjusted. In addition, the number of Additional
Shares shall be subject to adjustment in the same manner as the Exchange Rate in
accordance with the provisions of Section 2.14 hereof.

                  The following table sets forth the Share Price and number of
Additional Shares to be received per $1,000 principal amount of Notes:



                                                           Share Price

                  The actual Share Prices and Effective Dates may not be set
forth in the table, in which case:

                                    (a) if the Share Price is between two Share
Price amounts in the table or the Effective Date is between two dates in the
table, the Additional Shares shall be determined by straight-line interpolation
between the number of Additional Shares set forth for the higher and lower Share
Price amounts and the two dates, as applicable, based on a 365-day year;

                                    (b) if the Share Price is in excess of
$55.00 per Lexington Common Share (subject to adjustment as specified in the
second preceding paragraph), no Additional Shares shall be issued upon an
exchange of Notes;

                                    (c) if the Share Price is less than $21.04
per Lexington Common Share (subject to adjustment as specified in the second
preceding paragraph), no Additional Shares shall be issued upon an exchange of
Notes.

                  Notwithstanding the foregoing, in no event shall the Exchange
Rate (including any Additional Shares) issuable upon an exchange of Notes exceed
47.5285 shares per $1,000 principal amount of Notes, subject to adjustment in
the same manner as the Exchange Rate pursuant to Section 2.14 hereof. All
calculations under this Section 2.10 shall be the responsibility of the Issuer.

                  Section 2.11. Exchange Rights.

                  Subject to the restrictions on ownership of Lexington Common
Shares as set forth in Section 2.15 hereof and to the conditions set forth
herein, Holders may surrender their Notes for exchange into cash, and with
respect to any portion in excess of the Principal Return, cash, Lexington Common
Shares or a combination of cash and Lexington Common Shares, at the Issuer's
option, at the applicable Exchange Rate prior to the close of business on the
second Business Day immediately preceding the Stated Maturity of the Notes
either (x) at any time on or after January 15, 2026 or (y) under any of the
other circumstances set forth in this Section 2.11.

                                    (a) Exchange Upon Satisfaction of Market
Price Condition. A Holder may surrender any of its Notes for exchange during any
calendar quarter beginning after March 31, 2007 (and only during such calendar
quarter) if, and only if, the Closing Sale Price of Lexington Common Shares for
at least 20 Trading Days (whether or not consecutive) in the period of 30
consecutive Trading Days ending on the last Trading Day of the preceding
calendar quarter as determined by the Issuer is more than 125% of the Exchange
Price per Lexington Common Share in effect on the applicable Trading Day. The
Board of Trustees of the Parent Guarantor shall make appropriate adjustments, in
its good faith determination, to account for any adjustment to the Exchange Rate
that becomes effective, or any event requiring an adjustment to the Exchange
Rate where the ex-dividend date of the event occurs, during that 30 consecutive
Trading-Day period.

                                    (b) Exchange Upon Satisfaction of Trading
Price Condition. A Holder may surrender any of its Notes for exchange during the
five consecutive Trading-Day period following any five consecutive Trading Days
in which the Trading Price per $1,000


                                      -17-



principal amount of Notes (as determined following a reasonable request by a
Holder of the Notes) was less than 98% of the product of the Closing Sale Price
of Lexington Common Shares multiplied by the applicable Exchange Rate.

                  The Trustee shall have no obligation to determine the Trading
Price of the Notes unless the Issuer shall have requested such determination,
and the Issuer shall have no obligation to make such request unless a Holder
provides the Issuer with reasonable written evidence that the Trading Price per
$1,000 principal amount of the Notes would be less than 98% of the product of
the Closing Sale Price of Lexington Common Shares and the Exchange Rate,
whereupon the Issuer shall instruct the Trustee in writing to determine the
Trading Price of the Notes beginning on the next Trading Day and on each
successive Trading Day until the Trading Price is greater than or equal to 98%
of the product of the Closing Sale Price of Lexington Common Shares and the
Exchange Rate.

                                    (c) Exchange Upon Notice of Redemption. A
Holder may surrender for exchange any of the Notes called for redemption at any
time prior to the close of business on the second Business Day prior to the
Redemption Date, even if the Notes are not otherwise exchangeable at such time.
The right to exchange Notes called for redemption pursuant to this clause (c)
shall expire after the close of business on the second Business Day prior to the
Redemption Date unless the Issuer defaults in making the payment due upon
redemption.

                                    (d) Exchange Upon Specified Transactions. If
the Parent Guarantor elects to:

                                         (i) distribute to all holders of
Lexington Common Shares rights entitling them to purchase, for a period expiring
within 45 days, Lexington Common Shares at less than the Closing Sale Price of
Lexington Common Shares on the Trading Day immediately preceding the declaration
date of the distribution; or

                                         (ii) distribute to all holders of
Lexington Common Shares assets, debt securities or rights to purchase securities
of the Parent Guarantor, the Issuer or the other Operating Partnerships, which
distribution has a per share value exceeding 15% of the Closing Sale Price of
Lexington Common Shares on the Trading Day immediately preceding the declaration
date of such distribution,

the Issuer and the Parent Guarantor shall notify the Holders of the Notes in
writing at least 25 Business Days prior to the ex-dividend date for such
distribution. Following the giving of such notice, Holders may surrender their
Notes for exchange at any time until the earlier of the close of business on the
Business Day prior to the ex-dividend date or an announcement that such
distribution shall not take place; provided, however, that a Holder may not
exercise this right to exchange if the Holder may participate, on an
as-exchanged basis, in the distribution without an exchange of Notes. The
ex-dividend date is the first date upon which a sale of the Lexington Common
Shares does not automatically transfer the right to receive the relevant
distribution from the seller of Lexington Common Shares to its buyer.


                                      -18-



                  In addition, if the Parent Guarantor or the Issuer is party to
a consolidation, merger, binding share exchange or a sale, lease or other
transfer of all or substantially all of the consolidated assets of the Parent
Guarantor or the Issuer pursuant to which all of the outstanding Lexington
Common Shares would be exchanged for cash, securities or other property that is
not otherwise a Change of Control, a Holder may surrender Notes for exchange at
any time from and including the date that is 25 Business Days prior to the
anticipated effective time of the transaction up to and including five Business
Days after the actual date of such transaction. The Issuer and the Parent
Guarantor shall notify Holders as promptly as practicable following the date the
Issuer or the Parent Guarantor publicly announces such transaction (but in no
event less than 25 Business Days prior to the anticipated effective time of such
transaction).

                  If a Change of Control occurs as a result of a transaction
described in clauses (1) or (2) of the definition of "Change of Control", a
Holder shall have the right to exchange its Notes at any time from and including
the Effective Date of such transaction up to and including the 30th Business Day
following the Effective Date of the transaction, provided that, if a Holder has
already delivered an Optional Repurchase Notice or a Change of Control Purchase
Notice with respect to a Note, such Holder may not surrender such Note for
exchange until it has withdrawn such notice in accordance with the applicable
provisions of Section 2.08 or 2.09 hereof, as the case may be. The Issuer and
the Parent Guarantor shall notify Holders as promptly as practicable following
the date that the Issuer or the Parent Guarantor publicly announces such Change
of Control (but in no event later than five Business Days prior to the Effective
Date of such Change of Control).

                  If the Issuer or the Parent Guarantor is a party to a
consolidation, merger, binding share exchange or a sale, lease or other transfer
of all or substantially all of the consolidated assets of the Parent Guarantor
or the Issuer pursuant to which all of the Lexington Common Shares are exchanged
for cash, securities or other property, then from and after the effective time
of the transaction, any exchange of Notes, including the Exchange Value and Net
Shares deliverable in connection with such exchange, shall be based on, and
without limiting the obligation to pay the Principal Return in cash, the Holders
shall be entitled to receive for any Net Shares, the kind and amount of cash,
securities or other property (the "Applicable Consideration") that the Holder
would have received if such Holder had exchanged its Notes for Lexington Common
Shares immediately prior to the effective time of the transaction. For purposes
of the foregoing, where a consolidation, merger, binding share exchange or a
sale, lease or other transfer of all or substantially all of the consolidated
assets of the Parent Guarantor involves a transaction that causes Lexington
Common Shares to be converted into the right to receive more than a single type
of consideration based upon any form of shareholder election, the Applicable
Consideration shall be deemed to be the weighted average of the types and
amounts of consideration received by the holders of Lexington Common Shares that
affirmatively make such an election. At the time of any transaction described in
this paragraph, the Issuer or the Parent Guarantor or the successor or
purchasing Person, as the case may be, shall execute with the Trustee a
supplemental indenture (which shall comply with the Trust Indenture Act as in
force at the date of execution of such supplemental indenture) providing that
each Note shall be exchangeable into the Applicable Consideration. Such
supplemental indenture shall provide for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided in this First
Supplemental Indenture.



                                      -19-



                  The Issuer shall cause notice of the execution of such
supplemental indenture to be mailed to each Holder of Notes, at its address
appearing on the Security Register, within 20 days after execution thereof.
Failure to deliver such notice shall not affect the legality or validity of such
supplemental indenture.

                  The above provisions shall similarly apply to successive
reclassifications, changes, consolidations, mergers, binding share exchanges,
combinations, sales and transfers.

                  If a Change of Control occurs prior to January 20, 2012 as a
result of a transaction described in clauses (1) or (2) of the definition
thereof, the Issuer shall adjust the Exchange Rate for Notes tendered for
exchange in connection with such a Change of Control transaction, as described
in Section 2.10 hereof.

                                    (e) Exchange Upon Delisting of Lexington
Common Shares. A Holder of Notes may surrender any of its Notes for exchange at
any time beginning on the first Business Day after the Lexington Common Shares
have ceased to be listed on a U.S. national or regional securities exchange for
a 30 consecutive Trading Day period. The Issuer shall promptly notify the
Trustee in writing upon the delisting of the Lexington Common Shares.

                                    (f) Partial Exchanges and Withdrawal of
Purchase Notices. A Holder may exchange fewer than all of its Notes so long as
the Notes exchanged are an integral multiple of $1,000 principal amount and the
remaining principal amount of Notes is in an authorized denomination. If a
Holder has delivered an Optional Repurchase Notice or a Change of Control
Purchase Notice with respect to a Note, such Holder may not surrender such Note
for exchange until it has withdrawn such notice in accordance with the
applicable provisions of Section 2.08 or 2.09 hereof, as the case may be.

                  Section 2.12. Exchange Settlement. Upon an exchange of Notes,
the Issuer shall deliver, in respect of each $1,000 principal amount of Notes
tendered for exchange in accordance with their terms, (a) cash in an amount (the
"Principal Return") equal to the lesser of (1) the principal amount of the Notes
surrendered for exchange and (2) the Exchange Value, and (b) if the Exchange
Value is greater than the Principal Return, an amount (the "Net Amount") in cash
or Lexington Common Shares with an aggregate value equal to the difference
between the Exchange Value and the Principal Return.

                  The Issuer may elect to deliver any portion of the Net Amount
in cash (the "Net Cash Amount") or Lexington Common Shares, and any portion of
the Net Amount the Issuer elects to deliver in Lexington Common Shares (the "Net
Shares") shall be the sum of the Daily Share Amounts for each Trading Day during
the Applicable Exchange Period. Prior to the close of business on the second
Trading Day following the date on which Notes are tendered for exchange, the
Issuer shall inform Holders of such Notes of its election to pay cash for all or
a portion of the Net Amount and, if applicable, the portion of the Net Amount
that shall be paid in cash and the portion that shall be delivered in the form
of Net Shares.

                  The Issuer shall deliver cash in lieu of any fractional
Lexington Common Shares issuable in connection with payment of the Net Shares
based upon the Average Price.


                                      -20-



                  The "Daily Share Amount" for each $1,000 principal amount of
Notes and each Trading Day in the Applicable Exchange Period is equal to the
greater of:

                                    (a) zero; and

                                    (b) a number of Lexington Common Shares
determined by the following formula:
                 _                                               _
                |(CSP x ER)-($1,000 + the Net Cash Amount, if any)|
                |-------------------------------------------------|
                |_                  20 x CSP                     _|

                  where


                  CSP = the Closing Sale Price of Lexington Common Shares on
                  such Trading Day; provided that if the Notes have become
                  exchangeable or convertible into securities or property other
                  than Lexington Common Shares, "CSP" is equal to the average of
                  the Closing Sale Prices of such securities for each Trading
                  Day in the Applicable Exchange Period or, in the case of
                  other, property, the fair market value thereof as determined
                  in good faith by the Board of Trustees of the Parent
                  Guarantor, and


                  ER = the applicable Exchange Rate

                  The Issuer shall determine the Exchange Value, Principal
Return, Net Amount, Net Cash Amount and the number of Net Shares, as applicable,
promptly after the end of the Applicable Exchange Period. The Issuer shall pay
the Principal Return and cash in lieu of fractional shares, and deliver Net
Shares or pay the Net Cash Amount, or a combination thereof, as applicable, no
later than the third Business Day following the last Trading Day of the
Applicable Exchange Period.

                  Section 2.13. Exchange Procedures. To exchange Notes, a Holder
must satisfy the requirements set forth in this Section 2.13.

                  To exchange the Notes, a Holder must (a) (i) complete and
manually sign the irrevocable exchange notice on the reverse of the Note (or
complete and manually sign a facsimile of such notice) and deliver such notice
to the Exchange Agent at the office maintained by the Exchange Agent for such
purpose, (ii) surrender the Notes to the Exchange Agent and (iii) furnish
appropriate endorsements and transfer documents if required by the Exchange
Agent, the Parent Guarantor or the Trustee, with respect to Notes which are in
certificated form, or, (b) if the Notes are in book-entry form, comply with the
appropriate procedures of the Depositary and, in the case of certificated Notes
and Notes in book-entry form, pay any transfer or similar tax, if required. The
date on which the Holder satisfies all such requirements shall be deemed to be
the date on which the applicable Notes shall have been tendered for exchange.

                  Notes in respect of which a Holder has delivered an Optional
Repurchase Notice or Change of Control Purchase Notice may be exchanged only if
such notice is withdrawn in accordance with the terms of Section 2.08 or Section
2.09, as the case may be.


                                      -21-



                  In case any Note shall be surrendered for partial exchange,
the Issuer shall execute and the Trustee shall authenticate and deliver to, or
upon the written order of, the Holder of the Note so surrendered, without charge
to such holder, a new Note or Notes in authorized denominations in an aggregate
principal amount equal to the portion of the surrendered Notes not surrendered
for exchange. A Holder may exchange fewer than all of such Holder's Notes so
long as the Notes exchanged are an integral multiple of $1,000 principal amount
and the remaining principal amount of the Notes is in an authorized
denomination.

                  Upon surrender of a Note for exchange by a Holder, such Holder
shall deliver to the Issuer cash equal to the amount that the Issuer is required
to deduct and withhold under applicable law in connection with the exchange;
provided, however, if the Holder does not deliver such cash, the Issuer may
deduct and withhold from the amount of consideration otherwise deliverable to
such Holder the amount required to be deducted and withheld under applicable
law.

                  Upon exchange of a Note, a Holder shall not receive any cash
payment representing accrued and unpaid interest on such Note (unless such
exchange occurs after a Regular Record Date and on or prior to the Interest
Payment Date to which it relates). Instead, upon an exchange of Notes, the
Issuer shall deliver to tendering Holders only the consideration specified in
Section 2.12. Delivery of cash and Lexington Common Shares, if any, upon an
exchange of Notes shall be deemed to satisfy the Issuer's obligation to pay the
principal amount of the Notes and any accrued and unpaid interest, except as
otherwise provided herein. Accordingly, upon an exchange of Notes, except as
otherwise provided herein, any accrued and unpaid interest shall be deemed paid
in full rather than cancelled, extinguished or forfeited. In no event shall the
Exchange Rate be adjusted to account for accrued and unpaid interest on the
Notes.

                  Holders of Notes at the close of business on a Regular Record
Date for an interest payment shall receive payment of interest payable on the
corresponding Interest Payment Date notwithstanding the exchange of such Notes
at any time after the close of business on the applicable Regular Record Date.
Notes tendered for exchange by a Holder after the close of business on any
Regular Record Date for an interest payment and on or prior to the corresponding
Interest Payment Date must be accompanied by payment of an amount equal to the
interest that such Holder is to receive on such Notes on such Interest Payment
Date; provided, however, that no such payment shall be required to be made (1)
if such Notes have been called for redemption on a Redemption Date that is after
such Regular Record Date and on or prior to the second Business Day following
such Interest Payment Date or (2) with respect to overdue interest (including
Additional Interest), if any overdue interest exists at the time of exchange
with respect to such Notes.

                  Upon exchange of a Note, the Issuer, if it elects to deliver
Net Shares, shall pay any documentary, stamp or similar issue or transfer tax
due on the issue of the Net Shares upon the exchange, if any, unless the tax is
due because the Holder requests the shares to be issued or delivered to a person
other than the Holder, in which case the Holder must pay the tax due prior to
the delivery of such Net Shares. Certificates representing or evidencing
Lexington Common Shares shall not be issued or delivered unless all taxes and
duties, if any, payable by the Holder have been paid.


                                      -22-



                  A Holder of Notes, as such, shall not be entitled to any
rights of a holder of Lexington Common Shares. Such Holder shall only acquire
such rights upon the delivery by the Issuer, at its option, of Net Shares in
accordance with the provisions of Section 2.12 in connection with the exchange
by a Holder of Notes.

                  If a Holder exchanges more than one Note at the same time, the
number of Net Shares, if any, issuable upon the exchange shall be based on the
total principal amount of the Notes surrendered for exchange.

                  The Parent Guarantor shall, prior to issuance of any Notes
hereunder, and from time to time as may be necessary, reserve out of its
authorized but unissued Lexington Common Shares a sufficient number of Lexington
Common Shares to permit the exchange of the Notes at the applicable Exchange
Rate, assuming an election by the Issuer to satisfy the entire Net Amount by the
delivery of Lexington Common Shares. Any Lexington Common Shares delivered upon
an exchange of Notes shall be newly issued shares or treasury shares, shall be
duly and validly issued and fully paid and nonassessable and shall be free from
preemptive rights and free of any lien or adverse claim.

                  The Parent Guarantor shall endeavor promptly to comply with
all federal and state securities laws regulating the issuance and delivery of
Lexington Common Shares, if any, upon an exchange of Notes and, prior to
delivering any Lexington Common Shares upon an exchange of the Notes, shall
cause to have listed or quoted all such Lexington Common Shares on each U.S.
national securities exchange or over-the-counter or other domestic market on
which the Lexington Common Shares are then listed or quoted.

                  Except as set forth herein, no other payment or adjustment for
interest shall be made upon exchange of Notes.

                  Section 2.14. Exchange Rate Adjustments. The Exchange Rate
shall be adjusted from time to time as follows:

                                    (a) If the Parent Guarantor issues Lexington
Common Shares as a dividend or distribution on Lexington Common Shares to all
holders of Lexington Common Shares, or if the Parent Guarantor effects a share
split or share combination, the Exchange Rate shall be adjusted based on the
following formula:

                  ER(1) =           ER(0) x (OS(1)/OS(0))

                  where

                  ER(0) =           the Exchange Rate in effect immediately
                                    prior to the adjustment relating to such
                                    event

                  ER1   =           the new Exchange Rate in effect taking such
                                    event into account

                  OS(0) =           the number of Lexington Common Shares
                                    outstanding immediately prior to such event



                                      -23-



                  OS(1) =           the number of Lexington Common Shares
                                    outstanding immediately after such event.

Any adjustment made pursuant to this paragraph (a) shall become effective on the
date that is immediately after (x) the date fixed for the determination of
shareholders entitled to receive such dividend or other distribution or (y) the
date on which such split or combination becomes effective, as applicable. If any
dividend or distribution described in this paragraph (a) is declared but not so
paid or made, the new Exchange Rate shall be readjusted to the Exchange Rate
that would then be in effect if such dividend or distribution had not been
declared.

                                    (b) If the Parent Guarantor issues to all
holders of Lexington Common Shares any rights, warrants, options or other
securities entitling them for a period of not more than 45 days after the date
of issuance thereof to subscribe for or purchase Lexington Common Shares, or
issues to all holders of Lexington Common Shares securities convertible into
Lexington Common Shares for a period of not more than 45 days after the date of
issuance thereof, in either case at an exercise price per Lexington Common Share
or a conversion price per Lexington Common Share less than the Closing Sale
Price of Lexington Common Shares on the Business Day immediately preceding the
time of announcement of such issuance, the Exchange Rate shall be adjusted based
on the following formula:

                  ER(1) =           ER(0) x ((OS(0)+X)/(OS(0)+Y))

                  where

                  ER(0) =           the Exchange Rate in effect immediately
                                    prior to the adjustment relating to such
                                    event

                  ER(1) =           the new Exchange Rate taking such event into
                                    account

                  OS(0) =           the number of Lexington Common Shares
                                    outstanding immediately prior to such event

                  X     =           the total number of Lexington Common Shares
                                    issuable pursuant to such rights, warrants,
                                    options, other securities or convertible
                                    securities

                  Y     =           the number of Lexington Common Shares equal
                                    to the quotient of (A) the aggregate price
                                    payable to exercise such rights, warrants,
                                    options, other securities or convertible
                                    securities and (B) the average of the
                                    Closing Sale Prices of Lexington Common
                                    Shares for the 10 consecutive Trading Days
                                    prior to the Business Day immediately
                                    preceding the date of announcement for the
                                    issuance of such rights, warrants, options,
                                    other securities or convertible securities.

                  If the application of the foregoing formula would result in a
decrease in the Exchange Rate, no adjustment to the Exchange Rate shall be made.


                                      -24-



                  For purposes of this paragraph (b), in determining whether any
rights, warrants, options, other securities or convertible securities entitle
the holders to subscribe for or purchase, or exercise a conversion right for,
Lexington Common Shares at less than the applicable Closing Sale Price of
Lexington Common Shares, and in determining the aggregate exercise or conversion
price payable for such Lexington Common Shares, there shall be taken into
account any consideration received by the Parent Guarantor for such rights,
warrants, options, other securities or convertible securities and any amount
payable on exercise or conversion thereof, with the value of such consideration,
if other than cash, to be determined by the Board of Trustees of the Parent
Guarantor. If any right, warrant, option, other security or convertible security
described in this paragraph (b) is not exercised or converted prior to the
expiration of the exercisability or convertibility thereof, the new Exchange
Rate shall be readjusted to the Exchange Rate that would then be in effect if
such right, warrant, option, other security or convertible security had not been
so issued.

                                    (c) If the Parent Guarantor distributes
shares of its capital stock, evidences of indebtedness or other assets or
property to all holders of Lexington Common Shares, excluding:

                                         (i) dividends, distributions, rights,
warrants, options, other securities or convertible securities referred to in
paragraph (a) or (b) above,

                                         (ii) dividends or distributions paid
exclusively in cash, and

                                         (iii) Spin-Offs described below in this
paragraph (c),

then the Exchange Rate shall be adjusted based on the following formula:

                  ER(1) =           ER(0) x (SP(0)/(SP(0)-FMV))

                  where

                  ER(0) =           the Exchange Rate in effect immediately
                                    prior to the adjustment relating to such
                                    event

                  ER(1) =           the new Exchange Rate taking such event into
                                    account

                  SP(0) =           the average of the Closing Sale Prices of
                                    Lexington Common Shares for the 10
                                    consecutive Trading Days prior to the
                                    Business Day immediately preceding the
                                    earlier of the record date or the
                                    ex-dividend date for such distribution

                  FMV   =           the fair market value (as determined in good
                                    faith by the Board of Trustees of the Parent
                                    Guarantor) of the shares of capital stock,
                                    evidences of indebtedness, assets or
                                    property distributed with respect to each
                                    outstanding Lexington Common Share on the
                                    earlier of the record date or the
                                    ex-dividend date for such distribution.



                                      -25-



                  An adjustment to the Exchange Rate made pursuant to the
immediately preceding paragraph shall be made successively whenever any such
distribution is made and shall become effective on the day immediately after the
date fixed for the determination of holders of Lexington Common Shares entitled
to receive such distribution.

                  If the Parent Guarantor distributes to all holders of
Lexington Common Shares, capital stock of any class or series, or similar equity
interest, of or relating to a subsidiary or other business unit of the Parent
Guarantor (a "Spin-Off"), the Exchange Rate shall be adjusted based on the
following formula:

                  ER(1) =           ER(0) x ((FMV(0)+MP(0))/MP(0))

                  where

                  ER(0) =           the Exchange Rate in effect immediately
                                    prior to the adjustment relating to such
                                    event

                  ER(1) =           the new Exchange Rate taking such event into
                                    account

                  FMV(0)=           the value, based on the average of the
                                    Closing Sale Prices of the capital stock or
                                    similar equity interest distributed to
                                    holders of Lexington Common Shares over the
                                    first 10 consecutive Trading Days after the
                                    effective date of the Spin-Off applicable to
                                    one Lexington Common Share

                  MP(0) =           the average of the Closing Sale Prices of
                                    Lexington Common Shares over the first 10
                                    consecutive Trading Days after the effective
                                    date of the Spin-Off.

                  An adjustment to the Exchange Rate made pursuant to the
immediately preceding paragraph shall occur on the 10th Trading Day after the
effective date of the Spin-Off.

                  If any such dividend or distribution described in this
paragraph (c) is declared but not paid or made, the new Exchange Rate shall be
readjusted to be the Exchange Rate that would then be in effect if such dividend
or distribution had not been declared.

                                    (d) If the Parent Guarantor makes any cash
dividend or distribution during any of its quarterly fiscal periods (without
regard to when paid) to all holders of Lexington Common Shares in an aggregate
amount that, together with other cash dividends or distributions made in respect
of that quarterly fiscal period, exceeds the product of $0.375 (the "Reference
Dividend") multiplied by the number of Lexington Common Shares outstanding on
the record date for such distribution, the Exchange Rate shall be adjusted based
on the following formula:

                  ER(1) =           ER(0) x ((SP(0)-RD)/(SP(0)-C))

                  where



                                      -26-



                  ER(0)  =          the Exchange Rate in effect immediately
                                    prior to the adjustment relating to such
                                    event

                  ER(1)  =          the new Exchange Rate taking such event into
                                    account

                  SP(0)  =          the average of the Closing Sale Prices of
                                    Lexington Common Shares for the 10
                                    consecutive Trading Days prior to the
                                    business day immediately preceding the
                                    earlier of the record date or the day prior
                                    to the ex-dividend date for such
                                    distribution

                  RD     =          the Reference Dividend

                  C      =          the amount in cash per Lexington Common
                                    Share that the Parent Guarantor distributes
                                    to holders of Lexington Common Shares in
                                    respect of such quarterly fiscal period.

                  An adjustment to the Exchange Rate made pursuant to this
paragraph (d) shall become effective on the date immediately after the date
fixed for the determination of holders of Lexington Common Shares entitled to
receive such dividend or distribution. If any dividend or distribution described
in this paragraph (d) is declared but not so paid or made, the new Exchange Rate
shall be readjusted to the Exchange Rate that would then be in effect if such
dividend or distribution had not been declared.

                  Notwithstanding the foregoing, if an adjustment to the
Exchange Rate is required to be made as a result of a dividend or distribution
that is not a quarterly dividend or distribution either in whole or in part, the
Reference Dividend shall be deemed to be zero for purposes of determining the
adjustment to the Exchange Rate as a result of such dividend or distribution.

                  The Reference Dividend shall be subject to adjustment in a
manner that is inversely proportional to adjustments to the Exchange Rate;
provided that no adjustment shall be made to the Reference Dividend for any
adjustment made to the Exchange Rate pursuant to this paragraph (d).

                                    (e) If the Parent Guarantor or any of its
subsidiaries makes a payment in respect of a tender offer or exchange offer for
Lexington Common Shares to the extent that the cash and value of any other
consideration included in the payment per Lexington Common Share exceeds the
Closing Sale Price of a Lexington Common Share on the Trading Day next
succeeding the last date on which tenders or exchanges may be made pursuant to
such tender or exchange offer (the "Expiration Time"), the Exchange Rate shall
be adjusted based on the following formula:

                  ER(1) =           ER(0) x ((AC + (SP(1) x OS(1)))/(SP(1) x
                                    OS(0)))

                  where

                  ER(0) =           the Exchange Rate in effect immediately
                                    prior to the adjustment relating to such
                                    event

                                      -27-



                  ER(1) =           the new Exchange Rate taking such event into
                                    account

                  AC    =           the aggregate value of all cash and any
                                    other consideration (as determined in good
                                    faith by the Board of Trustees of the Parent
                                    Guarantor) paid or payable for Lexington
                                    Common Shares purchased in such tender or
                                    exchange offer

                  OS(0) =           the number of Lexington Common Shares
                                    outstanding immediately prior to the date
                                    such tender or exchange offer expires

                  OS(1) =           the number of Lexington Common Shares
                                    outstanding immediately after such tender or
                                    exchange offer expires (after giving effect
                                    to the purchase or exchange of shares
                                    pursuant to such tender or exchange offer)

                  SP(1) =           the average of the Closing Sale Prices of
                                    Lexington Common Shares for the 10
                                    consecutive Trading Days commencing on the
                                    Trading Day next succeeding the date such
                                    tender or exchange offer expires.

                  If the application of the foregoing formula would result in a
decrease in the Exchange Rate, no adjustment to the Exchange Rate shall be made.

                  Any adjustment to the Exchange Rate made pursuant to this
paragraph (e) shall become effective on the date immediately following the
Expiration Time. If the Parent Guarantor or one of its subsidiaries is obligated
to purchase Lexington Common Shares pursuant to any such tender or exchange
offer but is permanently prevented by applicable law from effecting any such
purchase or all such purchases are rescinded, the new Exchange Rate shall be
readjusted to be the Exchange Rate that would be in effect if such tender or
exchange offer had not been made.

                                    (f) Notwithstanding the foregoing, in the
event of an adjustment to the Exchange Rate pursuant to paragraph (d) or (e)
above, in no event shall the Exchange Rate exceed 47.5285, subject to adjustment
pursuant to paragraphs (a), (b) and (c) above.

                                    (g) If the Parent Guarantor has in effect a
rights plan while any Notes remain Outstanding, Holders of Notes shall receive,
upon an exchange of Notes in respect of which the Issuer has elected to deliver
Net Shares, in addition to such Net Shares, rights under any shareholder rights
agreement that the Parent Guarantor may then have in effect unless, prior to
exchange, the rights have expired, terminated or been redeemed or unless the
rights have separated from the Lexington Common Shares. If the rights provided
for in the rights plan adopted by the Parent Guarantor have separated from the
Lexington Common Shares in accordance with the provisions of the applicable
shareholder rights agreement so that Holders of Notes would not be entitled to
receive any rights in respect of Lexington Common Shares into which Notes are
exchangeable, the Exchange Rate shall be adjusted at the time of separation as
if the Parent Guarantor had distributed to all holders of Lexington Common
Shares capital stock, evidences of indebtedness or other assets or property
pursuant to


                                      -28-




paragraph (c) above, subject to readjustment upon the subsequent expiration,
termination or redemption of the rights.

                  In addition to the adjustments pursuant to paragraphs (a)
through (g) above, the Issuer may increase the Exchange Rate in order to avoid
or diminish any income tax to holders of Lexington Common Shares resulting from
any dividend or distribution of capital stock (or rights to acquire Lexington
Common Shares) or from any event treated as such for income tax purposes. The
Issuer may also, from time to time, to the extent permitted by applicable law,
increase the Exchange Rate by any amount for any period if the Issuer has
determined that such increase would be in the best interests of the Issuer or
the Parent Guarantor. If the Issuer makes such determination, it shall be
conclusive and Issuer shall mail to Holders of the Notes a notice of the
increased Exchange Rate and the period during which it shall be in effect at
least fifteen (15) days prior to the date the increased Exchange Rate takes
effect in accordance with applicable law.

                  If, in connection with any adjustment to the Exchange Rate as
set forth in this Section 2.14, a Holder shall be deemed for U.S. federal tax
purposes to have received a distribution or other income from the Issuer, the
Issuer may set off any withholding tax it or the Parent Guarantor reasonably
believes it is required to collect with respect to any such deemed distribution
or payment against cash payments of interest in accordance with the provisions
of Section 2.05 hereof or from cash and Lexington Common Shares, if any,
otherwise deliverable to a Holder upon an exchange of Notes in accordance with
the provisions of Section 2.12 hereof or a redemption or repurchase of a Note in
accordance with the provisions of Section 2.07, 2.08 or 2.09 hereof.

                  The Issuer shall not make any adjustment to the Exchange Rate
if Holders of the Notes are permitted to participate, on an as-exchanged basis,
in the transactions described above without exchanging their Notes.

                  Notwithstanding anything to the contrary contained herein, in
addition to the other events set forth herein on account of which no adjustment
to the Exchange Rate shall be made, the applicable Exchange Rate shall not be
adjusted for:

                                    (i) the issuance of any Lexington Common
Shares pursuant to any public or private follow-on offering of such shares;

                                    (ii) the issuance of any Lexington Common
Shares pursuant to any present or future plan providing for the reinvestment of
dividends or interest payable on securities of the Issuer or those of the Parent
Guarantor and the investment of additional optional amounts in Lexington Common
Shares under any plan;

                                    (iii) the issuance of any Lexington Common
Shares or options or rights to purchase those shares pursuant to any present or
future employee, trustee or consultant benefit plan, employee agreement or
arrangement or program of the Parent Guarantor or the Issuer;


                                      -29-



                                    (iv) the issuance of any Lexington Common
Shares pursuant to any option, warrant, right, or exercisable, exchangeable or
convertible security outstanding as of the date the Notes were first issued;

                                    (v) a change in the par value of Lexington
Common Shares;

                                    (vi) accumulated and unpaid dividends or
distributions;

                                    (vii) as a result of a tender offer solely
to holders of less than 100 Lexington Common Shares; and

                                    (viii) the issuance of limited partnership
units by the Operating Partnerships for cash or property and the issuance of
Lexington Common Shares for cash or property or the payment of cash upon
redemption thereof; provided that the acquisition of property upon issuance of
the limited partnership units will not result in any anti-dilution adjustments
pursuant to this Section 2.14.

                  No adjustment in the Exchange Rate shall be required unless
the adjustment would require an increase or decrease of at least 1% of the
Exchange Price. If the adjustment is not made because the adjustment does not
change the Exchange Price by at least 1%, then the adjustment that is not made
shall be carried forward and taken into account in any future adjustment. All
required calculations shall be made to the nearest cent or 1/1000th of a share,
as the case may be. Notwithstanding the foregoing, if the Notes are called for
redemption, all adjustments not previously made shall be made on the 10th
Business Day preceding the applicable Redemption Date.

                  Whenever the Exchange Rate is adjusted as herein provided, the
Parent Guarantor or the Issuer shall as promptly as reasonably practicable file
with the Trustee and any Exchange Agent other than the Trustee an Officers'
Certificate setting forth the Exchange Rate after such adjustment and setting
forth a brief statement of the facts requiring such adjustment. Promptly after
delivery of such certificate, the Parent Guarantor or the Issuer shall prepare a
notice of such adjustment of the Exchange Rate setting forth the adjusted
Exchange Rate and the date on which each adjustment becomes effective and shall
mail such notice of such adjustment of the Exchange Rate to the Holders of the
Notes upon request within 20 Business Days of the Effective Date of such
adjustment. Failure to deliver such notice shall not affect the legality or
validity of any such adjustment.

                  For purposes of this Section 2.14, the number of Lexington
Common Shares at any time outstanding shall not include shares held in the
treasury of the Parent Guarantor but shall include shares issuable in respect of
scrip certificates issued in lieu of fractions of Lexington Common Shares.

                  Notwithstanding anything in this Section 2.14 to the contrary,
in no event shall the Exchange Rate be adjusted so that the Exchange Price would
be less than $0.01.

                  Section 2.15. Ownership Limit; Withholding. Notwithstanding
any other provision of the Notes or the instructions contained herein, no Person
may own, or be deemed to


                                      -30-



own by virtue of the attribution rules of the Code, more than 9.8% in value of
Lexington Common Shares or the issued and outstanding shares of any of the
Parent Guarantor's other classes or series of shares of beneficial interest. In
case of requests for waivers or modifications of such limit by Persons that are
not individuals or treated as individuals under the Code, the Board of Trustees
of the Parent Guarantor is required to waive or modify such limit if, among
other things, evidence satisfactory to it is presented that such ownership would
not jeopardize the Parent Guarantor's status as a real estate investment trust
for U.S. federal income tax purposes. Notwithstanding any other provision of the
Notes or the instructions contained herein, no Holder of Notes shall be entitled
to exchange such Notes for Lexington Common Shares to the extent that receipt of
such shares would cause such Holder (together with such Holder's affiliates) to
exceed the ownership limit contained in the Declaration of Trust of the Parent
Guarantor as in effect from time to time.

                  At the Maturity of the principal of the Notes, whether at
Stated Maturity or upon earlier redemption or repurchase of Notes or otherwise,
and as otherwise required by law, the Issuer may deduct and withhold from the
amount of consideration otherwise deliverable to such Holder the amount required
to be deducted and withheld under applicable law.

                  Section 2.16. Merger, Consolidation or Sale. Solely for
purposes of the Notes, Section 801 and Section 803 of the Indenture are hereby
modified and amended to include, in addition to clauses (1), (2) and (3), the
following additional clause:

                  "(4) if as a result of such transaction the Notes become
                  exchangeable or convertible into common stock or other
                  securities issued by a third party, such third party shall
                  assume or fully and unconditionally guarantee all obligations
                  under the Notes and the Indenture."

                  Section 2.17. Satisfaction and Discharge. The provisions of
Sections 401, 402, 403 and 404 of the Original Indenture shall not be applicable
to the Notes. This Indenture shall be discharged and shall cease to be of
further effect as to all Notes when either (i) all Notes theretofore
authenticated and delivered (except lost, stolen or destroyed Notes which have
been replaced or paid as provided in Section 306 of the Original Indenture) have
been delivered to the Trustee for the Notes for cancellation or (ii) (A) all
Notes have not theretofore been delivered to the Trustee for cancellation, after
the Notes have become due and payable, whether on the date of the Stated
Maturity of the principal amount of the Notes, any Redemption Date, Optional
Repurchase Date or Change of Control Repurchase Date or upon exchange or
otherwise, cash or Lexington Common Shares in accordance with the terms hereof
and the Issuer has irrevocably deposited or caused to be deposited with such
Trustee as trust funds in trust an amount of cash in any combination of currency
or currency unit in which the Notes are payable (except as otherwise specified
pursuant to Section 301 of the Original Indenture for the Notes) and/or
Lexington Common Shares sufficient to pay and discharge the entire indebtedness
on such Notes for principal and accrued and unpaid interest (including
Additional Interest, if any), if any, and pay all other sums payable on, and
securities deliverable in respect of, the Notes and under the Indenture in
respect of such Notes; (B) no Event of Default or event which with the giving of
notice or the lapse of time, or both, would become an Event of Default shall
have occurred and be continuing on the date of such deposit and no Event of
Default under Section 501(5) or


                                      -31-



Section 501(6) of the Original Indenture shall have occurred and be continuing
on the 123rd day after such date; (C) the Issuer has paid, or caused to be paid,
all sums payable by it under the Indenture in respect of the Notes; and (D) the
Issuer has delivered irrevocable instructions to the Trustee for the Notes under
the Indenture to apply the deposited money and the Lexington Common Shares
toward the payment of such Notes. In addition, the Issuer must deliver an
Officers' Certificate and an Opinion of Counsel to the Trustee for the Notes
stating that all conditions precedent to satisfaction and discharge have been
satisfied.

                  Section 2.18. Events of Default; Waiver of Past Defaults.

                                    (a) Section 501 of the Original Indenture is
modified and amended for purposes of the Notes to add the following Events of
Default:

                  "default in the delivery when due of the Exchange Value on the
                  terms set forth herein and in the Notes, upon exercise of a
                  Holder's exchange right in accordance with the terms hereof
                  and of the Notes and the continuation of such default for 10
                  days;"

                                     - and -

                  "failure of the Issuer to provide an Issuer Notice within 20
                  days after the occurrence of a Change of Control as provided
                  in Section 2.09 of the First Supplemental Indenture, and such
                  failure continues for 5 Business Days."

                                    (b) Section 513 of the Original Indenture is
modified and amended for purposes of the Notes to add the following as clause
(3):

                  "(3) in respect of the failure by the Issuer to exchange any
                  Notes in accordance with the provisions of this Indenture."

                  Section 2.19. Modification. Section 902 of the Original
Indenture, as modified by this Section 2.19, shall apply solely to the Notes,
and Section 902 of the Original Indenture, other than as modified by this
Section 2.19, shall not apply to the Notes. As modified by this Section 2.19
with respect to the Notes, Section 902 of the Original Indenture is as follows:

                  "With the consent of the Holders of a majority in principal
amount of all Outstanding Notes affected by such supplemental indenture (voting
together as a single class), by Act of said Holders delivered to the Issuer, the
Parent Guarantor and the Trustee, the Issuer, when authorized by or pursuant to
a Board Resolution, the Parent Guarantor (when authorized by or pursuant to a
Parent Guarantor's Board Resolution), and the Trustee may enter into an
indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders of Notes
under this Indenture; provided, however, that no such supplemental indenture
shall, without the consent of the Holder of each Outstanding Note affected
thereby:



                                      -32-



                                    (a) change the Stated Maturity of the
principal of, or any installment interest (including Additional Interest, if
any) on, the Notes;

                                    (b) reduce the principal amount of, the rate
of interest (including Additional Interest, if any) on, or change the timing or
reduce the amount payable on the redemption of, the Notes;

                                    (c) make any change that impairs or
adversely affects the rights of a Holder to exchange Notes in accordance
herewith;

                                    (d) change the Place of Payment, or the coin
or currency, for payment of principal of, or interest (including Additional
Interest, if any) on, the Notes;

                                    (e) reduce or alter the method of
computation of any amount payable upon redemption, repayment or purchase of any
Notes by the Company (or the time when such redemption, repayment or purchase
may be made);

                                    (f) impair the right to institute suit for
the enforcement of any payment on or with respect to Notes or the delivery of
the Exchange Value as required by the Indenture upon an exchange of Notes;

                                    (g) release the Guarantee of any Guarantor
(except as otherwise provided in the Indenture) or make any changes to such
Guarantees in a manner adverse to the Holders;

                                    (h) reduce the percentage in principal
amount of the Outstanding Notes, the consent of whose Holders is required for
any such supplemental indenture, or the consent of whose Holders is required for
any waiver with respect to the Outstanding Notes (or compliance with specified
provisions of the Indenture or specified defaults and consequences thereunder)
or to reduce the quorum or voting requirements set forth in the Indenture; or

                                    (i) modify any of the provisions of this
Section 902, Section 513 or Section 1013 of the Original Indenture, except to
increase the required percentage to effect such action or to provide that
specified other provisions of the Indenture which may not be modified or waived
without the consent of the Holders of each Outstanding Note affected thereby.

                  It shall not be necessary for any Act of Holders under this
Section 2.19 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such Act shall approve the substance
thereof.

                  A supplemental indenture which changes or eliminates any
covenant or other provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities, or which
modifies the rights of the Holders of Securities of such series with respect to
such covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series."


                                      -33-



                  Section 2.20. Full and Unconditional Guarantee by the Parent
Guarantor and the Subsidiary Guarantors. The provisions of ARTICLE FOURTEEN of
the Original Indenture shall be applicable to the Notes, with each of the Parent
Guarantor and the Subsidiary Guarantors being guarantors of the Notes.

                  Section 2.21. [Intentionally Omitted]

                  Section 2.22. Calculations in Respect of the Notes. Except as
otherwise specifically stated herein or in the Notes, all calculations to be
made in respect of the Notes shall be the obligation of the Issuer. All
calculations made by the Issuer or its agent as contemplated pursuant to the
terms hereof and of the Notes shall be made in good faith and, absent manifest
error, shall be final and binding on the Issuer and the Holders. The Issuer
shall provide a schedule of calculations to the Trustee, and the Trustee shall
be entitled conclusively to rely upon the accuracy of the calculations by the
Issuer without independent verification. The Trustee shall forward calculations
made by the Issuer to any Holder of Notes upon written request within 20
Business Days after the effective date of any adjustment.

                  The Trustee shall not at any time be under any duty or
responsibility to any holder of Notes to determine or calculate the Exchange
Rate or whether any facts exist which may require any adjustment of the Exchange
Rate, or with respect to the nature or extent or calculation of any such
adjustment when made, or with respect to the method employed, or herein or in
any supplemental indenture provided to be employed, in making the same. The
Trustee shall not be accountable with respect to the validity or value (or the
kind or amount) of any Lexington Common Shares, or of any capital stock, other
securities or other assets or property, which may at any time be issued or
delivered upon the exchange or conversion of any Notes; and the Trustee makes no
representations with respect thereto. The Trustee shall not be responsible for
any failure of the Issuer to issue, transfer or deliver any Lexington Common
Shares or stock certificates or other securities or property or cash upon the
surrender of any Notes for the purpose of exchange or conversion or to comply
with any of the duties, responsibilities or covenants of the Issuer or Parent
Guarantor contained in this Article 2. Without limiting the generality of the
foregoing, the Trustee shall not be under any responsibility to determine the
correctness of any provisions relating either to the kind or amount of shares of
capital stock or other securities or other assets or property (including cash)
receivable by holders of Notes upon the exchange or conversion of their Notes
after any event referred to herein or to any adjustment to be made with respect
thereto, but may accept as conclusive evidence of the correctness of any such
provisions, and shall be protected in relying upon, the Officers' Certificate
(which the Issuer shall be obligated to file with the Trustee prior to the
execution of any such supplemental indenture) with respect thereto.

                  Section 2.23. Authorized Denominations. The Notes shall be
issued in denominations of $1,000 and integral multiples thereof and payments of
principal and interest (including Additional Interest) on the Notes shall be
made in U.S. dollars.

                  Section 2.24. Exchange Agent, Paying Agent and Securities
Registrar. U.S. Bank National Association is hereby appointed as Exchange Agent,
Paying Agent and the Security Registrar for the Notes. The Security Register for
the Notes shall be maintained by the Security Registrar in the Borough of
Manhattan, The City of New York. The rights, privileges,


                                      -34-



protections, immunities and benefits given to the Trustee pursuant to the
Indenture, including, without limitation, its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities
with respect to the Notes.

                  Section 2.25. Restrictions on Transfer. (a) Every Note (and
all Notes issued in exchange therefor or in substitution thereof) that bears or
is required under this Section 2.25(a) to bear the legend set forth in this
Section 2.25(a) (together with any Lexington Common Shares issued upon exchange
of such Notes, collectively, the "Restricted Securities") shall be subject to
the restrictions on transfer set forth in this Section 2.25(a) (including those
set forth in the legend below) unless such restrictions on transfer shall be
waived by written consent of the Issuer, and the Holder of each such Restricted
Security, by such Holder's acceptance thereof, agrees to be bound by all such
restrictions on transfer. As used in this Section 2.25(a), the term "transfer"
means any sale, pledge, loan, transfer or other disposition whatsoever of any
Restricted Security or any interest therein.

                  Until the expiration of the holding period applicable to sales
of Restricted Securities under Rule 144(k) under the Securities Act (or any
successor provision), any certificate evidencing a Restricted Security shall
bear a legend in substantially the following form, unless such Restricted
Security has been sold pursuant to a registration statement that has been
declared effective under the Securities Act (and which continues to be effective
at the time of such transfer) or sold pursuant to Rule 144 under the Securities
Act or any similar provision then in force, or unless otherwise agreed by the
Issuer in writing, with written notice thereof to the Trustee:

                  THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS, AND
MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS
ACQUISITION HEREOF, THE HOLDER:

                  (1) REPRESENTS THAT IT IS A "QUALIFIED INSTITUTIONAL BUYER"
(AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IS AWARE THAT THE TRANSFER IS
BEING MADE IN RELIANCE ON RULE 144A UNDER THE SECURITIES ACT AND IS PURCHASING
THIS SECURITY IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT;

                  (2) AGREES THAT IT SHALL NOT, WITHIN TWO YEARS AFTER THE LATER
OF THE ORIGINAL ISSUANCE OF THIS SECURITY AND THE LAST DATE ON WHICH LEXINGTON
REALTY TRUST OR THE LEXINGTON MASTER LIMITED PARTNERSHIP OR AN AFFILIATE THEREOF
WAS THE OWNER OF THIS SECURITY, RESELL OR OTHERWISE TRANSFER THIS SECURITY OR
THE LEXINGTON COMMON SHARES ISSUABLE UPON EXCHANGE OF SUCH SECURITY EXCEPT (A)
TO LEXINGTON REALTY TRUST OR THE LEXINGTON MASTER LIMITED PARTNERSHIP OR ANY OF
THEIR RESPECTIVE SUBSIDIARIES, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN
COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) PURSUANT TO THE
EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF
AVAILABLE), OR (D) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED

                                      -35-



EFFECTIVE UNDER THE SECURITIES ACT AND WHICH CONTINUES TO BE EFFECTIVE AT THE
TIME OF SUCH RESALE OR TRANSFER; AND

                  (3) AGREES THAT IT SHALL DELIVER TO EACH PERSON TO WHOM THIS
SECURITY IS TRANSFERRED PURSUANT TO CLAUSE 2(B) ABOVE A NOTICE SUBSTANTIALLY TO
THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF THIS SECURITY
WITHIN TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUE DATE OF THIS SECURITY AND
THE LAST DATE ON WHICH LEXINGTON REALTY TRUST OR THE LEXINGTON MASTER LIMITED
PARTNERSHIP OR AN AFFILIATE THEREOF WAS THE OWNER OF THIS SECURITY, THE HOLDER
MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE
MANNER OF SUCH TRANSFER AND SUBMIT THIS SECURITY TO THE TRUSTEE. IF THE PROPOSED
TRANSFER IS PURSUANT TO CLAUSE 2(C) ABOVE, THE HOLDER MUST, PRIOR TO SUCH
TRANSFER, FURNISH TO THE TRUSTEE AND THE LEXINGTON MASTER LIMITED PARTNERSHIP,
SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS LEXINGTON REALTY
TRUST OR THE LEXINGTON MASTER LIMITED PARTNERSHIP OR THE TRUSTEE MAY REASONABLY
REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION
FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT. THIS LEGEND SHALL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF
THIS SECURITY PURSUANT TO CLAUSE 2(C) OR 2(D) ABOVE OR THE EXPIRATION OF TWO
YEARS FROM THE LATER OF THE ORIGINAL ISSUE DATE OF THIS SECURITY AND THE LAST
DATE ON WHICH LEXINGTON REALTY TRUST OR THE LEXINGTON MASTER LIMITED PARTNERSHIP
OR AN AFFILIATE THEREOF WAS THE OWNER OF THIS SECURITY. THE HOLDER OF THIS
SECURITY IS ENTITLED TO THE BENEFITS OF A REGISTRATION RIGHTS AGREEMENT (AS SUCH
TERM IS DEFINED IN THE INDENTURE REFERRED TO ON THE REVERSE HEREOF) AND, BY ITS
ACCEPTANCE HEREOF, AGREES TO BE BOUND BY AND TO COMPLY WITH THE PROVISIONS OF
SUCH REGISTRATION RIGHTS AGREEMENT.

                  Each share certificate representing Lexington Common Shares
issued upon conversion of Notes bearing a legend will bear a comparable legend
(except that the legend will indicate that the two-year period commenced on the
original issuance of the Notes) until it is removed in conformity with
applicable securities laws.

                  Any Notes that are Restricted Securities and as to which such
restrictions on transfer shall have expired in accordance with their terms or as
to conditions for removal of the foregoing legend set forth therein have been
satisfied may, upon surrender of such Note for exchange to the Securities
Registrar in accordance with the provisions of this Section 2.25, be exchanged
for a new Note or Notes, of like tenor and aggregate principal amount, which
shall not bear the restrictive legend required by this Section 2.25(a). If such
Restricted Security surrendered for exchange is represented by a global Note
bearing the legend set forth in this Section 2.25(a), the principal amount of
the legended global Note shall be reduced by the appropriate principal amount
and the principal amount of a global Note without the legend set forth in this
Section 2.25(a) shall be increased by an equal principal amount. If a global
Note without the legend set forth in this Section 2.25(a) is not then
outstanding, the Issuer shall


                                      -36-



execute and the Trustee shall authenticate and deliver an unlegended global Note
to the Depositary.

                  In the event Rule 144(k) under the Securities Act (or any
successor provision) is amended to shorten the two-year period under Rule
144(k), then, the references in the restrictive legends set forth above to "TWO
YEARS," and in the corresponding transfer restrictions described above, and in
the Notes and the Lexington Common Shares shall be deemed to refer to such
shorter period, from and after receipt by the Trustee of an Officers'
Certificate and an Opinion of Counsel to that effect. As soon as reasonably
practicable after the public announcement of the effectiveness of any such
amendment to shorten the two-year period under Rule 144(k), unless such changes
would otherwise be prohibited by, or would cause a violation of, the federal
securities laws applicable at the time, the Issuer shall provide to the Trustee
an Officers' Certificate and an Opinion of Counsel as to the effectiveness of
such amendment and the effectiveness of such change to the restrictive legends
and transfer restrictions.

                                    (a) Any Restricted Securities, prior to the
expiration of the holding period applicable to sales thereof under Rule 144(k)
under the Securities Act (or any successor provision), purchased or owned by the
Issuer or any Affiliate thereof may not be resold by the Issuer or such
Affiliate and shall be surrendered to the Trustee for cancellation. Upon
expiration of the holding period applicable Restricted Securities under Rule
144(k) under the Securities Act (or any successor provision), the Notes may, to
the extent permitted by applicable law, be reissued or sold or may be
surrendered to the Trustee for cancellation. Any Notes surrendered for
cancellation may not be reissued or resold and shall be cancelled promptly by
the Trustee.

                                    (b) The Trustee shall have no obligation or
duty to monitor, determine or inquire as to compliance with any restrictions on
transfer imposed under this instrument or under applicable law with respect to
any transfer of any interest in any Note other than to require delivery of such
certificates and other documentation or evidence as are expressly required by,
and to do so if and when expressly required by, the terms of this instrument,
and to examine the same to determine substantial compliance as to form with the
express requirements hereof.

                  Section 2.26. Rule 144A Information Requirement. If at any
time within the period prior to the expiration of the holding period applicable
to sales thereof under Rule 144(k) under the Securities Act (or any successor
provision), the Parent Guarantor or the Issuer is not subject to Section 13 or
15(d) under the Exchange Act, the Parent Guarantor or the Issuer, as the case
may be, covenant and agree that it will make available to any holder or
beneficial holder of Notes or any Lexington Common Shares issued upon exchange
thereof which continue to be Restricted Securities in connection with any sale
thereof and any prospective purchaser of Notes or such Lexington Common Shares
designated by such holder or beneficial holder, the information required
pursuant to Rule 144A(d)(4) under the Securities Act upon the request of any
holder or beneficial holder of the Notes or such Lexington Common Shares, all to
the extent required to enable such holder or beneficial holder to sell its Notes
or Lexington Common Shares without registration under the Securities Act within
the limitation of the exemption provided by Rule 144A unless a resale shelf
registration statement in respect of the Notes and the Lexington Common Shares
is available.



                                      -37-



                  Section 2.27. Provision of Financial Information. (a) So long
as the Notes are outstanding and whether or not required by the Commission, the
Parent Guarantor and the Issuer will furnish to the Trustee within 15 days of
the time periods specified in the Commission's rules and regulations: (i) all
annual and quarterly financial information that would be required to be
contained in filings with the Commission on Forms 10-K and 10-Q if the Parent
Guarantor and the Issuer were required to file those filings, including a
related "Management's Discussion and Analysis of Financial Condition and Results
of Operations" and, with respect to the annual information only, a report on the
annual financial statements by the certified independent accountants of the
Parent Guarantor and the Issuer; and (ii) all current reports that would be
required to be filed with the Commission on Form 8-K if the Parent Guarantor and
the Issuer were required to file such reports.

                  (b) If the Parent Guarantor or the Issuer is not subject to
Sections 13 and 15(d) of the Exchange Act, the Parent Guarantor or the Issuer,
as the case may be, will (A) furnish to the holders of the Notes, without cost
to such holders, a copy of the information and reports referred to in clause (a)
above within 15 days of the time periods specified in the Commission's rules and
regulations, and (B) upon written request and payment of the reasonable cost of
duplication and delivery, promptly supply to any prospective holder of the debt
securities a copy of the information and reports referred to in clause (a).

                  In addition, whether or not required by the Commission, the
Parent Guarantor and the Issuer will file a copy of the information and reports
referred to above with the Commission for public availability within the time
periods specified in the Commission's rules and regulations (unless the
Commission will not accept such a filing).

                  The Parent Guarantor and the Issuer will be deemed to have
satisfied the obligation to deliver the foregoing financial information if the
information is filed on the Commission's EDGAR system in the timeframes
otherwise applicable for delivery to the Trustee, to Holders or prospective
Holders, as the case may be.

                  Delivery of such reports, information and documents to the
Trustee shall be for information purposes only and the Trustee's receipt of such
shall not, in the absence of gross negligence, bad faith or willful misconduct
on its part, constitute constructive notice of any information contained therein
or determinable from information contained therein, including each of the
Issuer's and Parent Guarantor's compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on Officers'
Certificates).

                  Section 2.28. Additional Interest Notice. In the event that
the Issuer is required to pay Additional Interest to Holders of Notes pursuant
to the Registration Rights Agreement, the Issuer shall provide written notice
("Additional Interest Notice") to the Trustee of its obligation to pay
Additional Interest no later than fifteen (15) calendar days prior to the
proposed payment date for Additional Interest, and the Additional Interest
Notice shall set forth the amount of Additional Interest to be paid by the
Issuer on such payment date. The Trustee shall not at any time be under any duty
or responsibility to any Holder of Notes to determine the Additional Interest,
or with respect to the nature, extent or calculation of the amount of Additional
Interest when made, or with respect to the method employed in such calculation
of the Additional Interest.

with any rule or regulation made pursuant thereto or with any rule or regulation
of any securities exchange or automated quotation system on which the Notes may

and Notes in book-entry form, pay any transfer or similar tax, if required. The
date on which the Holder satisfies all such requirements shall be deemed to be
