LEXINGTON CORPORATE PROPERTIES TRUST
355 Lexington Avenue
New York, New York  10017

Ladies and Gentlemen:

      We  have  acted  as  special  Maryland  counsel  to  Lexington   Corporate
Properties  Trust,  a  Maryland  statutory  real  estate  investment  trust (the
"Trust"),  in connection with a Registration  Statement on Form S-3 of the Trust
(File Number  333-109393) (the  "Registration  Statement"),  filed on October 2,
2003 with the Securities and Exchange Commission (the  "Commission"),  under the
Securities  Act of 1933, as amended (the "Act"),  for offering by the Trust from
time to time of up to  $400,000,000  in  aggregate  offering  price  of  certain
securities described in the Registration Statement. Pursuant to the Registration
Statement,  the Trust will issue and sell up to 6,900,000  shares of  beneficial
interest of the Trust (the  "Shares",  of which  6,000,000  shares are the "Firm
Shares" and up to an additional  900,000  shares are the "Option  Shares," which
may be issued and sold  pursuant  to an  underwriter's  over-allotment  option),
designated as Common Stock, par value $.0001 per share (the "Common Stock"),  in
an underwritten  public offering  pursuant to an Underwriting  Agreement,  dated
February  26,  2004 (the  "Underwriting  Agreement"),  by and  between  Wachovia
Capital  Markets,  LLC (the  "Underwriter"),  on the one  hand,  and the  Trust,
Lepercq  Corporate Income Fund L.P.,  Lepercq Corporate Income Fund II L.P., and
Net 3  Acquisition  L.P., on the other.  This opinion is being  provided at your
request  in  connection  with the  filing of a Current  Report on Form 8-K to be
filed with the  Commission  on or about March 1, and  supplements  our  opinion,
dated  October 1, 2003,  previously  filed as  Exhibit  5.1 to the  Registration
Statement.

      In our capacity as special Maryland counsel, we have reviewed originals or
copies, certified or otherwise identified to our satisfaction,  of the following
documents:

            (a) The  Declaration of Trust of the Trust,  as amended,  corrected,
      and supplemented to date (the "Declaration of Trust"), as certified by the
      Department  of  Assessments  and  Taxation of the State of  Maryland  (the
      "MSDAT").

            (b) The  By-Laws  (the  "By-Laws")  of the  Trust,  as  amended  and
      restated and in effect on the date hereof.

            (c)  The Underwriting Agreement.

            (d)  The Registration Statement.

                                                                   March 1, 2004
                                                                          Page 2


            (e) The final Prospectus dated October 22, 2003 (the  "Prospectus"),
      which forms a part of the  Registration  Statement,  and the related final
      Prospectus   Supplement   dated   February   26,  2004  (the   "Prospectus
      Supplement"), relating to the Shares.

            (f) The form of share certificate evidencing shares of Common Stock.

            (g) The  resolutions  of the  Board of  Trustees  of the  Trust or a
      committee   thereof  relating  to  the  organization  of  the  Trust,  the
      authorization of the Underwriting Agreement, and the authorization and the
      issuance of the Shares.

            (h) A short-form Good Standing  Certificate  for the Trust,  dated a
      recent date, issued by the MSDAT.

            (i) An Officer's Certificate (the "Certificate") of the Trust, dated
      a recent date, as to certain factual matters.

            (j) Such other  documents  as we have  considered  necessary  to the
      rendering of the opinion expressed below.

      In our examination of the aforesaid  documents,  we have assumed,  without
independent investigation, the genuineness of all signatures, the legal capacity
of all  individuals  who  have  executed  any of the  aforesaid  documents,  the
authenticity of all documents submitted to us as originals,  the conformity with
originals of all documents  submitted to us as copies (and the  authenticity  of
the originals of such copies), the absence of other agreements or understandings
among the parties that would modify the terms of the  proposed  transactions  or
the respective rights or obligations of the parties thereunder,  the accuracy of
the  representations  and warranties as to factual  matters of the Trust, as set
forth in the  Underwriting  Agreement,  and the accuracy and completeness of all
public records  reviewed by us. In making our examination of documents  executed
by parties other than the Trust, we have assumed that such parties had the power
(corporate,  trust,  partnership,  or  other)  to  enter  into and  perform  all
obligations  thereunder,  and we have also assumed the due  authorization by all
requisite  action  (corporate,  trust,  partnership,  or  other)  and the  valid
execution  and  delivery by such  parties of such  documents  and the  validity,
binding effect, and enforceability  thereof with respect to such parties.  As to
any facts materials to this opinion, we have relied solely upon the Certificate.

      Based  upon  the  foregoing,   subject  to  the  additional   assumptions,
qualifications,  and limitations  set forth below,  having regard for such legal
considerations  as we deem  relevant,  and limited in all respects to applicable
Maryland  law,  we are of the  opinion  and advise you that the Shares have been
duly  authorized by the Trust and, upon issuance and delivery to the Underwriter
against  payment  therefor  in  accordance  with the  terms of the  Underwriting
Agreement and the resolutions  authorizing  their  issuance,  the Shares will be
validly issued, fully paid, and non-assessable.

                                                                   March 1, 2004
                                                                          Page 3


      The  opinion  set  forth  herein is  subject  to  additional  assumptions,
qualifications, and limitations as follows:

            (a) We have made no  investigation  of, and we express no opinion as
      to,  the laws of any  jurisdiction  other  than  the laws of the  State of
      Maryland. To the extent that any documents referred to herein are governed
      by the laws of a jurisdiction  other than  Maryland,  we have assumed that
      the laws of such jurisdiction are the same as the laws of Maryland.

            (b) This opinion  concerns only the effect of the laws (exclusive of
      the  principles of conflict of laws) of the State of Maryland as currently
      in effect.  We assume no  obligation  to  supplement  this  opinion if any
      applicable  laws  change  after  the  date  hereof  or  if  any  facts  or
      circumstances  come to our  attention  after the date  hereof  that  might
      change this opinion.

            (c) We express no opinion as to compliance  with the  securities (or
      "blue  sky")  laws or the real  estate  syndication  laws of the  State of
      Maryland.

            (d) We  assume  that the final  share  certificates  evidencing  the
      Shares conform to the form of share  certificate  referred to in paragraph
      (f) of the listing of documents.

            (e) We assume that the  issuance of the Shares by the Trust will not
      cause any person to violate any of the  provisions of the  Declaration  of
      Trust relating to the Ownership  Limit, as defined in Article NINTH of the
      Declaration of Trust.

            (f) This opinion is limited to the matters set forth herein,  and no
      other opinion should be inferred beyond the matters expressly stated.

      We hereby  consent to the filing of this  opinion with the  Commission  as
Exhibit 5.1 to the Current  Report on Form 8-K and to the  reference to our firm
under the heading "Legal Matters" in the Prospectus  Supplement  relating to the
Shares.  In giving  our  consent,  we do not  thereby  admit  that we are in the
category of persons whose consent is required  under Section 7 of the Act or the
rules and  regulations of the Commission  thereunder.  We further consent to the
reliance on this  opinion by Paul,  Hastings  Janofsky & Walker LLP in rendering
its  opinion  to the  Trust in  connection  with the  filing  of the  Prospectus
Supplement.

                                    Very truly yours,

                                    /s/  PIPER RUDNICK LLP
