OnAt ~~April~~a meeting held on March 2318, ~~2007~~2009, the ~~Registrants~~Compensation ~~issued~~Committee a(the ~~press~~“Committee”) ~~release~~of ~~announcing~~the Board of Trustees (the ~~Registrants’~~“Board”) of Liberty Property Trust (the “Company”) approved the Liberty Property ~~financial~~Trust ~~results~~2009 Long-Term Incentive Plan (the “2009 Plan”), with the purpose of enhancing and refining the performance incentives provided to the named executive officers of the Company. The 2009 Plan is substantially similar in design to the Liberty Property Trust 2008 Long-Term Incentive Plan, in that it provides for an annual aggregate award (each, an “Award”) composed of (i) a grant of restricted stock units (approximately two-thirds of the ~~quarter~~total ~~ended~~targeted ~~March~~expected value of the Award), and (ii) 31a grant of stock options (approximately one-third of the total targeted expected value of the Award). When the Company’s common shares of beneficial interest, ~~2007~~$0.001 ~~The~~par ~~Registrants~~value (the “Common Shares”), are ~~furnishing~~issued with respect to the ~~press~~Awards they underlie, they will be issued under ~~release~~the asCompany’s ~~Exhibit 99~~Amended and Restated Share Incentive Plan, and shall generally be subject to ~~this~~the terms ~~Current~~and ~~Report~~conditions onof ~~Form~~that ~~8-K~~plan.

~~Item~~ Awards ~~9.01.~~under ~~Financial~~the ~~Statements~~2009 ~~and~~Plan ~~Exhibits.~~will have the following general features:

Restricted Stock Units. A “restricted stock unit” (aor “RSU” or “phantom stock”) ~~Financial~~under the ~~Statements~~2009 Plan consists of ~~Businesses~~a ~~Acquired.~~legally-binding ~~None.~~promise ~~(b)~~to ~~Pro~~pay ~~Forma~~the ~~Financial~~executive ~~Information.~~a ~~None.~~certain ~~(c)~~number ~~Shell~~of ~~Company~~the Common ~~Transactions.~~Shares ~~None.~~at the end of the Award Period (das defined below), ~~Exhibits~~to the extent certain annual performance criteria are met or exceeded.

Exhibit Number				Exhibit Title
	99			Press Release by the Registrants, dated April 23, 2007, furnished in accordance with Item 2.02 of this Current Report on Form 8-K.

The restricted stock units shall be eligible to be earned over the three-year period beginning on the date of grant (the “Award Period”), and shall be further subdivided into (i) a portion earned ratably over the Award Period on a year-by-year basis (each year constituting a related “Performance Period”), using a specific performance measure (the “First Portion”), and (ii) a portion earned over the full Award Period, using another specific performance measure (the “Second Portion”). Neither portion, however, would be payable until the end of the three-year Award Period. Any dividends that accumulate prior to the end of the Award Period will be paid if and when the related restricted stock units are redeemed and paid.

~~SIGNATURES~~ Under the 2009 Plan, the Committee has the ability to utilize a wide variety of performance measures on which to base each particular year’s grant of restricted stock units, and will act each year to designate the specific performance measures for that year. For the Awards granted under the 2009 Plan for 2009, as discussed more specifically below, these two measures are based, respectively, on the amount of the Company’s “funds from operations” (the “FFO Portion”) for the First Portion of the Award, and its total shareholder return (the “TSR Portion”) as compared to a relevant peer group for the Second Portion of the Award. The Committee has adopted a performance metrics schedule for the Awards to be granted under the 2009 Plan for 2009, listing the threshold at which the actual FFO Portion and TSR Portion will accrue, in relation to the specified target levels. These levels provide for specified awards upon attainment of stipulated percentages of the target level (and include a maximum number of Common Shares payable of 200% of both the First Portion and the Second Portion), with the Committee retaining discretion to reduce the award from the prescribed level as it deems fit.

~~Pursuant to the requirements of the Securities Exchange Act of 1934, each Registrant has duly~~1 ~~caused this report to be signed on its behalf by the undersigned hereunto duly authorized.~~

~~LIBERTY~~ The ~~PROPERTY~~restricted ~~TRUST~~stock ~~By:~~units ~~/s/~~that ~~George~~comprise J.the ~~Alburger~~First Portion will be split into three equal pieces, ~~Jr.~~corresponding ~~George~~to Jeach of the three years in the relevant Award Period. ~~Alburger~~Depending on how each year’s performance compares to the budget performance for that year using an annually-determined performance schedule, ~~Jr.~~a ~~Chief~~portion ~~Financial~~of ~~Officer~~the ~~LIBERTY~~related ~~PROPERTY~~restricted ~~LIMITED~~stock ~~PARTNERSHIP~~units ~~By:~~will ~~Liberty~~be deemed ~~Property~~earned ~~Trust~~for that year, ~~its~~and ~~sole~~will ~~General~~be ~~Partner~~payable ~~By:~~to /the participant in Common Shares (under the terms of the Company’s/ ~~George~~Amended J.and ~~Alburger,~~Restated ~~Jr.~~Share ~~George~~Incentive JPlan) at the end of the Award Period. The ~~Alburger~~restricted stock units that comprise the Second Portion are eligible to be earned on the basis of total shareholder return for the relevant Award Period, Jrusing an annually-determined performance schedule. ~~Chief~~The ~~Financial~~Second ~~Officer~~Portion will be deemed earned and payable to the participant in Common Shares (under the terms of the Company’s Amended and Restated Share Incentive Plan) at the end of the Award Period.

~~Dated:~~ If ~~April 24~~a recipient of an Award quits or is discharged for cause prior to the end of the Award Period, ~~2007~~all restricted stock units will be forfeited, even if they have (in the case of the First Portion that accrues on a year-by-year basis) already been earned. If the recipient of an Award is, instead, terminated without cause, or terminates by reason of death, disability or “Retirement” (as defined in the Company’s Amended and Restated Share Incentive Plan) prior to the end of the Award Period, the treatment of the restricted stock units shall be as set forth in the grant documents. The 2009 Plan also includes several customary restrictive covenants, subject to the Committee’s discretion, that would trigger forfeiture of an Award.

Options. Stock options granted under the 2009 Plan will be vested (and thus exercisable) solely on the basis of time and continued employment, with no regard to any performance criteria, at a rate of 20% of the total option component at the end of the first anniversary of the date of grant, 30% on the second anniversary, and the remainder on the third anniversary. In addition, they will become immediately vested and exercisable in full if the optionee ceases to be employed by, or provide services to, the Company by reason of death, disability, retirement or termination without cause. These terms and conditions are, generally, the terms and conditions that currently govern options granted to named executive officers as part of the Company’s LTI program, and thus do not represent a change in that component of the LTI program.

Also on March 18, 2009, the Committee made Awards under the 2009 Plan, such Awards to be granted as of the close of business on March 18, 2009. The Awards consisted of the following:

The determination of whether the Second Portion is earned and payable shall be made at the end of the Award Period.
