Exhibit 10.1

                    PENNSYLVANIA REAL ESTATE INVESTMENT TRUST
                                  (the "Trust")

                   Special Committee of the Board of Trustees


                               Statement Regarding
                  Adjustment of Earnout Performance Benchmarks
                                      Under
                         The TRO Contribution Agreement
                                      Dated
                                December 29, 1998


                  Pursuant to Section 5.19(b) of the TRO Contribution Agreement
dated as of July 30, 1997 (the "Agreement") by and among the Trust, PREIT
Associates, L.P. (the "Partnership"), the former shareholders and debtholders of
The Rubin Organization, Inc. (together, the "TRO Shareholders") and certain
other persons, the Trust's Board of Trustees formed a special committee of
trustees (the "Special Committee") to address and resolve certain matters after
closing pertaining to the transactions contemplated by the Agreement. Section
5.19(b) provides that the Special Committee shall, at the request of at least
one-third of the Partnership's outstanding Class A Units issued to the TRO
Shareholders and affiliates or any trustee of the Trust, consider whether
adjustments should be made to the applicable earnout performance benchmarks (the
"Benchmarks") contained in the Agreement as the result of, among other things,
the raising by the Trust of equity capital. Capitalized terms not otherwise
defined herein have the meanings set forth in the Agreement.

                  At the request of holders of more than one-third of the
outstanding Class A Units issued to TRO Shareholders and affiliates, the Special
Committee has reviewed the impact of the Trust's December 1997 public offering
of 4,600,000 Shares (the "Offering") on the Benchmarks, considering financial
projections for the Trust both before the Offering and on a pro forma basis,
taking into account the issuance of the new Shares and the general performance
of the Trust during the period following the closing of the transactions under
the Agreement.

                  Based on its analysis, the Special Committee has determined
that an adjustment to the Benchmarks as a result of the Offering would be
appropriate under Section 5.19 of the Agreement. The Special Committee has
concluded that, because the Offering will in the long run enhance the Trust's
financial performance, both the TRO Shareholders and the Trust should share the
dilutive effect of the Offering on FFO per outstanding share and that the
Benchmarks should be adjusted by applying a declining fraction of the dilution
resulting from the Offering in each successive year of the earnout.


                  The original Benchmarks and the effect of the new Shares on
FFO per outstanding share are set forth below:



Year                                    1998        1999         2000         2001         2002

each of which shall be deemed to be an original, and all of such counterparts
together shall be deemed to be one and the same instrument.
