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:

(a)         if such Notes are in certificated form, the certificate number(s) of the Notes which the Holder shall deliver to be repurchased;

(b)         the portion of the principal amount of 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.

-12-

The Paying Agent shall promptly notify the Issuer 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 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An Optional Repurchase Notice may be withdrawn in whole or in part by a Holder by means of a written notice of withdrawal delivered to the office of the Paying Agent prior to the close of business on the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 Day prior to the Optional Repurchase Date specifying:

(a)         the Holder’s name;

(b)         the principal amount of Notes in respect of which the Optional Repurchase Notice is being withdrawn, which must be an integral multiple of $1,000;

(c)         if the Notes subject to the notice of 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).

-13-

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 15, 2017, 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 (and 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 15, 2017, 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:

(d)         the Change of Control Purchase Price;

(e)         the name and address of the Trustee, the Paying Agent and the Conversion Agent;

-14-

(f)         that Notes in respect of which a Change of Control Purchase Notice is provided by a Holder shall not be convertible pursuant to Section 2.11 hereof 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 Issuer to repurchase their Notes;

(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.

The Issuer shall also disseminate a press release through PR 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 Issuer 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, the certificate number(s) of the Notes which the Holder shall deliver to be repurchased;

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

(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 in writing of the receipt by it of any Change of Control Purchase Notice.

-15-

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 Change of Control Purchase Price therefor.  Holders electing to require the Issuer to repurchase Notes must effect such transfer or delivery to the Paying Agent on or prior to the Change of Control Purchase Date to receive payment of the Change of Control Purchase Price on or within two Business Days after the Change of Control Purchase Date.  The Issuer shall pay the Change of Control Purchase Price within two Business Days after the later of the Change of Control Purchase Date or the time of such transfer or delivery of the Notes.

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

(c)         the principal amount of Notes in respect of which the Change of Control Purchase Notice is being withdrawn, which must be an integral multiple of $1,000; and

(d)         the principal amount of Notes, if any, 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 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 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 and all rights of the Holders of such Notes shall terminate (other than the right to receive the Change of Control Purchase 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 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.

-16-

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 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 Conversion Rate Upon Certain Change of Control Transactions.  If a Change of Control occurs prior to January 15, 2017 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 convert its Notes in connection with such Change of Control pursuant to Section 2.11(d), the Issuer shall increase the applicable Conversion Rate for such Notes surrendered for conversion by a number of additional Lexington Common Shares (the “Additional Shares”) as specified below.  A conversion of Notes shall be deemed for these purposes to be “in connection with” such a Change of Control if the notice of conversion of the Notes is received by the Conversion 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 Conversion 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 Conversion Rate immediately prior to the adjustment giving rise to the Share Price adjustment and the denominator of which is the Conversion Rate as so adjusted.  In addition, the number of Additional Shares shall be subject to adjustment in the same manner as the Conversion 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:

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 $40.00 per Lexington Common Share (subject to adjustment as specified in the second preceding paragraph), no Additional Shares shall be issued upon a conversion of Notes;

(c)         if the Share Price is less than $6.03 per Lexington Common Share (subject to adjustment as specified in the second preceding paragraph), no Additional Shares shall be issued upon a conversion of Notes.

Notwithstanding the foregoing, in no event shall the Conversion Rate (including any Additional Shares) issuable upon a conversion of Notes exceed 165.8374 shares per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 2.14 hereof.  All calculations under this Section 2.10 shall be the responsibility of the Issuer.

Section 2.11.     Conversion 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 conversion into cash, Lexington Common Shares or a combination of cash and Lexington Common Shares, at the Issuer’s option, at the applicable Conversion 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, 2029 or (y) under any of the other circumstances set forth in this Section 2.11.

-18-

(a)      Conversion Upon Satisfaction of Market Price Condition.  A Holder may surrender any of its Notes for conversion during any calendar quarter beginning after March 31, 2010 (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 130% of the Conversion Price per Lexington Common Share in effect on the applicable Trading Day.  The Board of Trustees of the Issuer shall make appropriate adjustments, in its good faith determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the ex-dividend date of the event occurs, during that 30 consecutive Trading-Day period.

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

(c)      Conversion Upon Notice of Redemption.  A Holder may surrender for conversion 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 convertible at such time.  The right to convert 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)      Conversion Upon Specified Transactions.  If the Issuer 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

-19-

(ii)           distribute to all holders of Lexington Common Shares assets, debt securities or rights to purchase securities of the Issuer or the 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 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 conversion 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 convert if the Holder may participate, on an as-converted basis, in the distribution without a conversion 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.

In addition, if 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 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 conversion 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 shall notify Holders as promptly as practicable following the date the Issuer 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 convert 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 conversion 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 shall notify Holders as promptly as practicable following the date that the Issuer 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 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 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 conversion of Notes, including the Daily Conversion Value and any shares deliverable in connection with such conversion, shall be based on the kind and amount of cash, securities or other property (the “Applicable Consideration”) that the Holder would have received if such Holder had converted 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 Issuer 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 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 convertible 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 Sixth Supplemental Indenture.

-20-

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 15, 2017 as a result of a transaction described in clauses (1) or (2) of the definition thereof, the Issuer shall adjust the Conversion Rate for Notes tendered for conversion in connection with such a Change of Control transaction, as described in Section 2.10 hereof.

(e)        Conversion Upon Delisting of Lexington Common Shares.  A Holder of Notes may surrender any of its Notes for conversion 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 Conversion and Withdrawal of Purchase Notices.  A Holder may convert fewer than all of its Notes so long as the Notes converted 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 conversion 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.     Conversion Settlement.  (a) Upon a conversion of Notes, the Issuer shall deliver to each converting holder, in respect of each $1,000 principal amount of Notes tendered for conversion, at the Issuer’s election, in full satisfaction of the Issuer’s Conversion Obligation, (1) Lexington Common Shares, together with cash in lieu of fractional shares, if any (a “Physical Settlement”), (2) a cash payment without delivery of any Lexington Common Shares (a “Cash Settlement”) or (3) a combination of cash and Lexington Common Shares, together with cash in lieu of fractional shares, if any (a “Combination Settlement”), in each case, as set forth below (the amounts so deliverable upon conversion of the Notes, the “Conversion Obligation”):

-21-

For conversions of Notes (other than conversions following a notice of redemption):

(i)           that occur prior to the date that is 15 Business days prior to the Stated Maturity, by the close of business on the Business Day following the Conversion Date, the Issuer shall notify converting Holders of the relevant Settlement Method and, if the Issuer elects a Combination Settlement, the dollar amount of the Conversion Obligation (the “Specified Dollar Amount”) that will be settled in cash;

(ii)           that occur on or after the date that is 15 Business Days prior to the Stated Maturity, the Issuer shall notify all Holders of the relevant Settlement Method and, if applicable, the related Specified Dollar Amount, by notice on or prior to the date that is 15 Business Days prior to the Stated Maturity (which shall apply to all conversions on or following the date that is 15 Business Days prior to the Stated Maturity).

For conversions of Notes that occur following delivery by the Issuer of a notice of redemption, as described in Section 2.11(c) hereof, the Issuer will notify converting Holders of the relevant Settlement Method and, if the Issuer elects Combination Settlement, the related Specified Dollar Amount.

If the Issuer does not specify a Settlement Method as set forth above, then Combination Settlement shall apply, and the related Specified Dollar Amount used in the settlement calculation set forth in paragraph (d) below will be $1,000.  Any such notice of a Settlement Method may not be revoked.

If the Issuer has elected a Physical Settlement with respect to any Notes tendered for conversion, the Issuer shall deliver, for each $1,000 principal amount of Notes, a number of Lexington Common Shares equal to the Conversion Rate, together with cash in lieu of fractional shares, on the third Business Day following the Conversion Date.

If the Issuer has elected a Cash Settlement with respect to any Notes tendered for conversion, the Issuer shall deliver, for each $1,000 principal amount of Notes, a cash payment equal to the sum of the Daily Conversion Values for each Trading Day during the relevant Applicable Conversion Period.  The Issuer shall make such payment on the third Business Day following the last day of the Applicable Conversion Period.

If the Issuer has elected or is deemed to have elected a Combination Settlement with respect to any Notes tendered for conversion, the Issuer shall deliver, for each $1,000 principal amount of Notes, the sum of the Daily Settlement Amounts for each Trading Day during the relevant Applicable Conversion Period.

The “Daily Settlement Amount” for each Trading Day during the Applicable Conversion Period shall consist of:

-22-

(i)           cash in an amount equal to the lesser of (x) 1/10 of the Specified Dollar Amount specified by the Issuer in the notice regarding the chosen Settlement Method (the “Daily Specified Dollar Amount”) and (y) the Daily Conversion Value on such Trading Day; and

(ii)           if the Daily Conversion Value on such Trading Day exceeds the Daily Specified Dollar Amount, a number of Lexington Common Shares (together with cash in lieu of any fractional shares) equal to (x) the difference between such Daily Conversion Value and the Daily Specified Dollar Amount, divided by (x) the Daily VWAP on such Trading Day.

The Issuer shall deliver such cash and Lexington Common Shares on the third Business Day following the last day of the Applicable Conversion Period; provided, however, that the Issuer will deliver the cash and Lexington Common Shares related to a conversion following a notice of redemption, as described in Section 2.11(c) hereof, during the 10-day period following the Redemption Date.

(b)        Upon conversion of any Notes, Holders shall not receive any separate cash payment for accrued and unpaid interest, except to the extent specified below.  The Issuer’s delivery to the Holder of Lexington Common Shares, cash or a combination of cash and Lexington Common Shares, as applicable, together with any cash payment for any fractional shares, into which a Note is convertible shall be deemed to satisfy in full the Issuer’s obligation to pay (i) the principal amount of the Notes so converted and (ii) accrued and unpaid interest to, but not including, the Conversion Date.  As a result, accrued and unpaid interest to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited.  Notes surrendered for conversion during the period from the close of business on any Record Date to the open of business on the immediately following interest payment date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that no such payment need be made (i) for conversions following the Record Date immediately preceding the Stated Maturity or (ii) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note.

(c)        The Issuer shall not issue fractional shares upon conversion of Notes.  If multiple Notes shall be surrendered for conversion at one time by the same Holder, the number of full Lexington Common Shares which shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered.  If any fractional share would be issuable upon the conversion of any Notes, the Issuer shall make payment therefor in cash in lieu of fractional shares based on:

(i)           if Physical Settlement applies, on the last reported sale price of Lexington Common Shares on the relevant Conversion Date; and

(ii)           if Combination Settlement applies, the Daily VWAP of Lexington Common Shares on the final Trading Day of the Applicable Conversion Period.

-23-

(d)        Solely for purposes of determining the payments and deliveries due upon conversion under this Section 2.12 and for purposes of the definitions of “Applicable Exchange Period,” “Daily VWAP” and “Scheduled Trading Day,”

“Trading Day” means a day on which (i) there is no Market Disruption Event and (ii) trading in Lexington Common Shares generally occurs on the New York Stock Exchange or, if Lexington Common Shares are not then listed on the New York Stock Exchange, on the principal other United States national or regional securities exchange on which Lexington Common Shares are then listed or, if Lexington Common Shares are not then listed on a United States national or regional securities exchange, on the principal other market on which Lexington Common Shares are then traded. If Lexington Common Shares (or other security for which a Daily VWAP must be determined) are not so listed or traded, “Trading Day” means a Business Day.

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

To convert the Notes, a Holder must (a) (i) complete and manually sign the irrevocable conversion notice on the reverse of the Note (or complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent at the office maintained by the Conversion Agent for such purpose, (ii) surrender the Notes to the Conversion Agent and (iii) furnish appropriate endorsements and transfer documents if required by the Conversion Agent, the Issuer 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 conversion.

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

In case any Note shall be surrendered for partial conversion, 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 conversion.  A Holder may convert fewer than all of such Holder’s Notes so long as the Notes converted 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 conversion 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 conversion; 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.

-24-

Upon conversion of a Note, a Holder shall not receive any cash payment representing accrued and unpaid interest on such Note (unless such conversion occurs after a Regular Record Date and on or prior to the Interest Payment Date to which it relates).  Instead, upon a conversion of Notes, the Issuer shall deliver to tendering Holders only the consideration specified in Section 2.12.  Delivery of Lexington Common Shares and/or cash upon a conversion 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 a conversion 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 Conversion 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 conversion of such Notes at any time after the close of business on the applicable Regular Record Date.  Notes tendered for conversion 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 conversion with respect to such Notes.

Upon conversion of a Note, the Issuer, if it elects Physical Settlement or Combination Settlement, shall pay any documentary, stamp or similar issue or transfer tax due on the issue of Lexington Common Shares upon the conversion, 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 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.

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 Lexington Common Shares in accordance with the provisions of Section 2.12 in connection with the conversion by a Holder of Notes.

The Issuer 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 conversion of the Notes at the applicable Conversion Rate, assuming an election by the Issuer of Physical Settlement.  Any Lexington Common Shares delivered upon a conversion 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.

-25-

The Issuer shall endeavor promptly to comply with all federal and state securities laws regulating the issuance and delivery of Lexington Common Shares, if any, upon a conversion of Notes and, prior to delivering any Lexington Common Shares upon a conversion 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 conversion of Notes.

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

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

CR1 = CR0 x (OS1/OS0)

where

CR0 = the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR1 = the new Conversion Rate in effect taking such event into account

OS0 = the number of Lexington Common Shares outstanding immediately prior to such event

OS1 = 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 Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b)         If the Issuer 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 Conversion Rate shall be adjusted based on the following formula:

-26-

CR1 = CR0 x ((OS0+X)/(OS0+Y))

where

CR0= the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR1 = the new Conversion Rate taking such event into account

OS0 = 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 Conversion Rate, no adjustment to the Conversion Rate shall be made.

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 Issuer 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 Issuer.  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 Conversion Rate shall be readjusted to the Conversion 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 Issuer 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,

-27-

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

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

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

CR1 = CR0 x (SP0/(SP0-FMV))

where

CR0 = the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR1 = the new Conversion Rate taking such event into account

SP0 = 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 Issuer) 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.

An adjustment to the Conversion 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 Issuer 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 Issuer (a “Spin-Off”), the Conversion Rate shall be adjusted based on the following formula:

CR1 = CR0 x ((FMV0+MP0)/MP0)

where

CR0 = the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR1 = the new Conversion Rate taking such event into account

FMV0 = 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

-28-

MP0 = 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 Conversion 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 Conversion Rate shall be readjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(d)         If the Issuer 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 $0.10 (the “Reference Dividend”) multiplied by the number of Lexington Common Shares outstanding on the record date for such distribution, the Conversion Rate shall be adjusted based on the following formula:

CR1 = CR0 x ((SP0-RD)/(SP0-C))

where

CR0 = the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR1 = the new Conversion Rate taking such event into account

SP0 = 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 Issuer distributes to holders of Lexington Common Shares in respect of such quarterly fiscal period.

An adjustment to the Conversion 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 Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

-29-

Notwithstanding the foregoing, if an adjustment to the Conversion 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 Conversion 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 Conversion Rate; provided that no adjustment shall be made to the Reference Dividend for any adjustment made to the Conversion Rate pursuant to this paragraph (d).

(e)         If the Issuer 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 Conversion Rate shall be adjusted based on the following formula:

CR1 = CR0 x ((AC + (SP1 x OS1))/(SP1 x OS0))

where

CR0 = the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR1 = the new Conversion 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 Issuer) paid or payable for Lexington Common Shares purchased in such tender or exchange offer

OS0 = the number of Lexington Common Shares outstanding immediately prior to the date such tender or exchange offer expires

OS1 = 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)

SP1 = 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.

-30-

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

Any adjustment to the Conversion Rate made pursuant to this paragraph (e) shall become effective on the date immediately following the Expiration Time.  If the Issuer 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 Conversion Rate shall be readjusted to be the Conversion 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 Conversion Rate pursuant to paragraph (d) or (e) above, in no event shall the Conversion Rate exceed 500 Lexington Common Shares per $1,000 principal amount of Notes, subject to adjustment pursuant to paragraphs (a), (b) and (c) above.

(g)         If the Issuer has in effect a rights plan while any Notes remain Outstanding, Holders of Notes shall receive, upon a conversion of Notes in respect of which the Issuer has elected to deliver Lexington Common Shares, in addition to such Lexington Common Shares, rights under any shareholder rights agreement that the Issuer may then have in effect unless, prior to conversion, 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 Issuer 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 convertible, the Conversion Rate shall be adjusted at the time of separation as if the Issuer had distributed to all holders of Lexington Common Shares capital stock, evidences of indebtedness or other assets or property pursuant to 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 Conversion 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 Conversion Rate by any amount for any period if the Issuer has determined that such increase would be in the best interests of the Issuer.  If the Issuer makes such determination, it shall be conclusive and Issuer shall mail to Holders of the Notes a notice of the increased Conversion Rate and the period during which it shall be in effect at least fifteen (15) days prior to the date the increased Conversion Rate takes effect in accordance with applicable law.

If, in connection with any adjustment to the Conversion 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 Issuer 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 a conversion 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.

-31-

The Issuer shall not make any adjustment to the Conversion Rate if Holders of the Notes are permitted to participate, on an as-converted basis, in the transactions described above without converting 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 Conversion Rate shall be made, the applicable Conversion 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 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 Issuer;

(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 Conversion Rate shall be required unless the adjustment would require an increase or decrease of at least 1% of the Conversion Price.  If the adjustment is not made because the adjustment does not change the Conversion 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.

-32-

Whenever the Conversion Rate is adjusted as herein provided, the Issuer shall as promptly as reasonably practicable file with the Trustee and any Conversion Agent other than the Trustee an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment.  Promptly after delivery of such certificate, the Issuer shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion 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 Issuer 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 Conversion Rate be adjusted so that the Conversion 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 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 Issuer’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 Issuer 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 Issuer’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 convert 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 Issuer 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 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.”

-33-

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 conversion 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(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 by deleting “or” at the end of Section 501(8) and by replacing the “.” at the end of Section 501(9) with a “;” and by:

(i) adding new paragraphs as follows:

“(10) default in the delivery when due of cash, Lexington Common Shares or a combination of cash and Lexington Common Shares on the terms set forth herein and in the Notes, upon exercise of a Holder’s conversion right in accordance with the terms hereof and of the Notes and the continuation of such default for 10 days; or

(11) 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 Sixth Supplemental Indenture, and such failure continues for 5 Business Days.” and

-34-

(ii) deleting Section 501(5) of the Original Indenture in its entirety and replace it with the following:

“(5) default in the payment of an aggregate principal amount exceeding $25,000,000 of any evidence of recourse indebtedness of the Issuer or any of the Guarantors, such default having continued after the expiration of any applicable grace period or having resulted in the acceleration of the maturity of that recourse indebtedness, but only if that recourse indebtedness is not discharged or such acceleration is not rescinded or annulled, in each case, within 30 days after written notice to the Issuer from the Trustee (or to the Issuer and the Trustee from Holders of at least 25% in principal amount of the Outstanding Notes);”.

(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 convert 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 and the Trustee, the Issuer, when authorized by or pursuant to a 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:

(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 convert Notes in accordance herewith;

-35-

(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 Issuer (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 cash, Lexington Common Shares or a combination of Lexington Common Shares as required by the Indenture upon a conversion 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.”

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

Section 2.21.     [Intentionally Omitted]

-36-

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 Conversion Rate or whether any facts exist which may require any adjustment of the Conversion 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 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.     Conversion Agent, Paying Agent and Securities Registrar.  U.S. Bank National Association is hereby appointed as Conversion 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, 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 conversion 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.

-37-

Until the expiration of the holding period applicable to sales of Restricted Securities under Rule 144(b)(1) 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 AN AFFILIATE THEREOF WAS THE OWNER OF THIS SECURITY, RESELL OR OTHERWISE TRANSFER THIS SECURITY OR THE LEXINGTON COMMON SHARES ISSUABLE UPON CONVERSION OF SUCH SECURITY EXCEPT (A) TO LEXINGTON REALTY TRUST 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), (D) PURSUANT TO ANY OTHER EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT, OR (E) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH RESALE OR TRANSFER; AND

-38-

(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 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 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 AN AFFILIATE THEREOF WAS THE OWNER OF THIS SECURITY.

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

In the event Rule 144(b)(1) under the Securities Act (or any successor provision) is amended to shorten the two year period under Rule 144(b)(1), then, the references in the restrictive legends set forth above to “ONE YEAR,” 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 one year period under Rule 144(b)(1), 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 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.

-39-

(a)         Any Restricted Securities, prior to the expiration of the holding period applicable to sales thereof under Rule 144(b)(1) 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(b)(1) 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(b)(1) under the Securities Act (or any successor provision), the Issuer is not subject to Section 13 or 15(d) under the Exchange Act, the Issuer covenants and agrees that it will make available to any holder or beneficial holder of Notes or any Lexington Common Shares issued upon conversion 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.

Section 2.27.     Provision of Financial Information.  (a) So long as the Notes are outstanding and whether or not required by the Commission, 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 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 Issuer; and (ii) all current reports that would be required to be filed with the Commission on Form 8-K if the Issuer were required to file such reports.

(b)           If the Issuer is not subject to Sections 13 and 15(d) of the Exchange Act, the Issuer 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).

-40-

In addition, whether or not required by the Commission, 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 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; provided, however, the Trustee shall have no responsibility whatsoever to determine if such filings have taken place.

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 the Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

ARTICLE THREE

FORM OF NOTES

Section 3.01.     Form of Notes.  The Notes and the Trustee’s certificate of authentication to be borne by such Notes shall be substantially in the form set forth in Exhibit A hereto.  Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends, endorsements or changes as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of the Indenture, or as may be required by the Depositary or by the National Association of Securities Dealers, Inc. in order for the Notes to be tradable on The PORTALSM Market or as may be required for the Notes to be tradable on any other market developed for trading of securities pursuant to Rule 144A or as may be required to comply with any applicable law or 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 be listed, or to conform to usage, or to indicate any special limitations or restrictions to which any particular Notes are subject.
