appropriate to express the opinion set forth below, subject to the assumptions,

         In expressing the opinions set forth below, we have assumed the

         1. Each individual executing any of the Documents, whether on behalf of
such individual or another person, is legally competent to do so;

         2. Each individual executing any of the Documents on behalf of a party

         3. Each of the parties (other than the Issuers) executing any of the

         5. The Securities will not be issued or transferred in violation of any
restriction contained in the Indenture, the Partnership Certificate, the

         To the extent that the obligations of the Issuers under the Indenture
may be dependent upon such matters, we have assumed for purposes of this opinion

the laws of its jurisdiction of organization; that the Trustee is duly qualified

the valid and binding obligation of the Trustee enforceable against the Trustee
in accordance with all applicable laws and regulations; and that the Trustee has
the requisite organization and legal power and authority to perform its
obligations under the Indenture.




         Based upon the foregoing, and subject to the assumptions, limitations
and qualifications stated herein, it is our opinion that:

         1. The Operating Partnership is a limited partnership duly formed and
existing under and by virtue of the laws of the State of Delaware and in good
standing with the OSSSD.

         2. The Company is a real estate investment trust duly formed and
existing under and by virtue of the laws of the State of Maryland and is in good
standing with the SDAT.

         3. Each of the Subsidiary Guarantors is duly incorporated, formed or
organized and existing as a corporation or other entity and in good standing in
the jurisdiction of its incorporation, formation or organization.

         4. The Notes are duly authorized for issuance and, when and if issued
and delivered against payment therefor and otherwise in accordance with the
Partnership Certificate, Partnership Agreement, the Resolutions, the
Underwriting Agreement and the Indenture, will constitute valid and binding
obligations of the Operating Partnership.

         5. The Guarantees of the Company are duly authorized for issuance and,
when and if issued and delivered against payment for the Notes and otherwise in
accordance with the Declaration of Trust, the Bylaws, the Resolutions, the
Underwriting Agreement and the Indenture, will constitute valid and binding
obligations of the Company.

         6. The Guarantees of each of the Subsidiary Guarantors are duly
authorized for issuance and, when and if issued and delivered against payment
for the Notes and otherwise in accordance with the Subsidiary Charters, the
Resolutions, the Underwriting Agreement and the Indenture, will constitute valid
and binding obligations of the Subsidiary Guarantors.

         In addition to the qualifications, exceptions and limitations elsewhere
set forth in this opinion letter, our opinions expressed above are also subject
to the effect of: (a) bankruptcy, insolvency, reorganization, moratorium and
other laws affecting creditors' rights (including, without limitation, the
effect of statutory and other law regarding fraudulent conveyances, fraudulent
transfers and preferential transfers), and (b) the exercise of judicial
discretion and the application of principles of equity, good faith, fair
dealing, reasonableness, conscionability and materiality (regardless of whether
the applicable agreements are considered in a proceeding in equity or at law).

         The foregoing opinions are limited to the substantive laws of the State
of Delaware, the State of Maryland, the State of New Jersey, the State of New
York, the Commonwealth of Pennsylvania and the Commonwealth of Virginia and we

of New Jersey, the State of New York, the Commonwealth of Pennsylvania and the
Commonwealth of Virginia, or as to federal or state laws regarding fraudulent
transfers. We assume no obligation to supplement this opinion letter if any
applicable law changes after the date hereof or if we become aware of any fact
that might change the opinion expressed herein after the date hereof.
