                                    PREAMBLE

         WHEREAS, Pennsylvania Real Estate Investment Trust (the "Trust")
established, and its shareholders approved, the Pennsylvania Real Estate
Investment Trust 2003 Equity Incentive Plan (the "Plan"), primarily in order to
award equity-based benefits to certain officers and other key employees of the
Trust and its "Related Corporations" and "Subsidiary Entities" (both as defined
in the Plan);

         WHEREAS, one kind of equity-based benefit that can be awarded under the
Plan is "Performance Shares," defined in the Plan as "an Award that entitles the
recipient to receive Shares, without payment, following the attainment of
designated individual or Corporate Performance Goals;"

         WHEREAS, the Trust's Executive Compensation and Human Resources
Committee (the "Committee") is responsible for the administration of the Plan
and may, pursuant to the powers granted to it thereunder, adopt rules and
regulations for the administration of the Plan and determine the terms and
conditions of each award granted thereunder;

         WHEREAS, the Committee established an outperformance program for
2005-2008 (the "Program") under the Plan for the benefit of certain officers of
the Trust and PREIT Services, LLC (one of the Trust's Subsidiary Entities)
whereby such officers would be awarded Performance Shares under the Plan, as set
forth in the Program, following the attainment of the corporate goal set forth
in the Program;

                  WHEREAS, the Committee wishes to revise how total return to
shareholders is determined under the Program by specifying that dividends paid
during the "Measurement Period" (as defined herein) are generally to be
considered reinvested in "Shares" (as defined in the Plan), and to make certain
other non-material changes;

         NOW, THEREFORE, effective as of January 1, 2005, the Pennsylvania Real
Estate Investment Trust 2005-2008 Outperformance Program is hereby amended and
restated by the Committee under the Plan with the following terms and
conditions:

          1. Purposes. The purposes of the Program are to motivate certain
     officers of the Employer to reach and exceed a challenging goal for the
     Trust of profitability and growth, and to focus the attention of the
     eligible officers on a critical financial indicator used to measure the
     success of companies in the same industry as the Trust.

Each Award Agreement and the Performance Shares which may be awarded thereunder
are subject to the terms of this Program, as well as to the terms of the Plan.

         4. Corporate Goal; Delivery of Performance Shares

          (a) If, for the Measurement Period, the Trust's per-share TRS exceeds
     Threshold One, then the Trust shall deliver to each Participant the number
     of Shares (rounded down to the nearest whole number of Shares) determined
     by first multiplying the Bonus Pool by the percentage set forth next to the
     Participant's name on Appendix A and then by dividing the product of such
     multiplication by Share Value on the last day of the Measurement Period.
     Awards will be payable under the Program to the extent that Shares remain
     available under the Plan. If the total number of Shares to be awarded
     exceeds the number of Shares available under the Plan, then the number of
     Shares for each Participant will be reduced on a pro rata basis based on
     each individual Participant's percentage. If, for the Measurement Period,
     the Trust's per-share TRS does not exceed Threshold One, the Trust shall
     not deliver any Performance Shares to the Participants. Also, except as
     provided in subsection (c) below, a Participant must be employed by an
     Employer on the last day of the Measurement Period in order to receive any
     Performance Shares under this Program.

                                      -3-



          (b) The following terms shall be defined as set forth below:

               (1) "Bonus Pool" means (subject to the last two sentences of this
          paragraph (1)) -

                    (A) An amount (if any) equal to 4.5% times TRS that is
               greater than Threshold One but less than or equal to Threshold
               Two times the number of Weighted Average Outstanding Shares; plus

                    (B) An amount (if any) equal to 6.5% times TRS that is
               greater than Threshold Two times the number of Weighted Average
               Outstanding Shares.

If TRS does not exceed Threshold One, the Bonus Pool shall be zero. Further, in
no event shall the Bonus Pool be greater than one percent of the Share Value of
the Shares outstanding plus the number of Shares which would be issuable upon
the redemption for Shares of all Operating Units outstanding and owned by
persons and entities other than the Trust and Subsidiary Entities, both as of
the last day of the Measurement Period.

               (2) "Morgan Stanley REIT Index" means the Morgan Stanley REIT
          Index or, in the event such index shall cease to be published, such
          other index as the Committee shall determine to be comparable thereto.

               (3) "Share Value" means, as applicable and except as provided in
          the following sentence, the average of the closing prices of one Share
          on the New York Stock Exchange (the "NYSE") (or, if not then listed on
          the NYSE, on the principal market or quotation system on which then
          traded) for the 20 days on which Shares were traded prior to January
          1, 2005 or the 20 days on which Shares were traded prior to and
          including the last day of the Measurement Period. In the event of a
          Business Combination approved by the shareholders of the Trust on or
          prior to December 31, 2008, Share Value shall mean the final price per
          Share agreed upon by the parties to the Business Combination.

               (4) "Operating Units" means limited partnership interests in
          PREIT Associates, L.P., a Delaware limited partnership.

               (5) "Threshold One" means, for purposes only of determining if
          TRS exceeds a certain dollar value, the greater of (i) an amount equal
          to a deemed increase in Share Value determined as of January 1, 2005
          through the end of the Measurement Period that equates to a 12% annual
          rate compounded as of the last day of each calendar year that ends
          during the Measurement Period (e.g., Share Value determined as of
          January 1, 2005 times 57.35% if the last day of the Measurement Period
          is December 31, 2008), and (ii) an amount equal to a deemed increase
          in Share Value determined as of January 1, 2005 through the end of the
          Measurement Period that equates to a rate equal to 115% of the total
          return of the Morgan Stanley REIT Index (expressed as a percentage)
          over the Measurement Period (i.e., Share Value determined as of
          January 1, 2005 times 115% of the percentage increase in such index
          (if any) over the Measurement Period).

                                      -4-



               (6) "Threshold Two" means, for purposes only of determining if
          TRS exceeds a certain dollar value, an amount equal to a deemed
          increase in Share Value determined as of January 1, 2005 through the
          end of the Measurement Period that equates to a 16% annual rate
          compounded as of the last day of each calendar year that ends during
          the Measurement Period (e.g., Share Value determined as of January 1,
          2005 times 81.06% if the last day of the Measurement Period is
          December 31, 2008).

               (7) "TRS" means total return to shareholders of the Trust - a
          dollar amount, not less than 0, equal to (i)(A) Share Value determined
          as of the last day of the Measurement Period plus (B) the sum of all
          cash dividends paid on a Share during the Measurement Period with each
          such dividend deemed reinvested, on the ex-dividend date for the
          dividend, in a fractional Share and at the opening price of a Share on
          such ex-dividend date, minus (ii) Share Value determined as of January
          1, 2005. Any fractional Share in which a dividend is deemed reinvested
          shall be subject to the adjustments described in Section 8. The
          Committee shall give effect to a dividend treated as special or
          extraordinary by the Morgan Stanley REIT Index in such manner as the
          Committee shall determine to be comparable to the methodology used in
          constructing such Index.

               (8) "Weighted Average Outstanding Shares" means the weighted
          average of (i) the Shares outstanding during the Measurement Period,
          plus (ii) the number of Shares which would be issuable upon the
          redemption by issuance of Shares of all Operating Units outstanding
          and owned by persons and entities other than the Trust and Subsidiary
          Entities during the Measurement Period, both numbers calculated as of
          the last day of the Measurement Period. Such weighted average shall be
          appropriately adjusted by the Committee to reflect any adjustment
          events described in Section 8 hereunder.

          (c) Notwithstanding the provisions in subsection (a) above, a
     Participant's Award Agreement shall provide that if, prior to the last day
     of the Measurement Period, the Participant (i) dies, terminates employment
     as a result of Disability, or terminates employment for Good Reason, or
     (ii) has his or her employment terminated by the Employer for reasons other
     than Cause, the Participant (or the Participant's beneficiary(ies)) shall
     be eligible to receive Performance Shares under the Program (if any) as
     though the Participant had remained employed by the Employer through the
     end of the Measurement Period. Except as, and to the extent and in the
     manner that, the Committee shall otherwise determine with respect to one or
     more Participants, the provisions of this subsection (c) shall not be
     applicable to any Participant who, on the date the Program was adopted by
     the Committee, was not employed under an Employment Agreement.

          (d) Within 30 days after the end of the Measurement Period, the
     Committee shall provide each Participant with a written determination of
     whether the Trust has or has not attained the Corporate Goal for the
     Measurement Period, the size of the Bonus Pool (if any)), and the
     calculations used to make such determinations. If Performance Shares are to
     be delivered under the Program, they shall be delivered to Participants on,
     or as soon as administratively practicable after, February 15, 2009 (unless
     a Participant elects otherwise pursuant to subsection (e) below) or, if a
     Change in Control occurs before January 1, 2009, within 30 days after the
     last day of the Measurement Period ending on (or, if applicable, after) the
     Change in Control.

                                      -5-



          (e) Except in the event of a Change in Control, if Performance Shares
     are to be delivered under the Program, a Participant may elect to defer
     delivery (and the Trust shall defer issuance) of all or a portion of the
     Performance Shares until, as specified in the Participant's deferral
     election agreement: (i) the Participant's separation from service from the
     Trust's controlled group of entities or (ii) a date chosen by the
     Participant. The Participant may also elect in the deferred election
     agreement to receive Performance Shares upon the occurrence of an
     "unforeseeable emergency," as defined in section 409A(a)(2)(B)(ii) of the
     Code, to the extent not prohibited by that section of the Code and
     regulations issued thereunder, if any. If the Participant's death occurs
     during the deferral period, the Participant's Performance Shares and Shares
     and cash attributable to DERs (see the following paragraphs in this
     subsection (e)) shall be delivered in a single sum to the Participant's
     beneficiary(ies) as soon as administratively practicable after the
     Participant's death.

         Participants who make a deferral election under this subsection (e)
shall be awarded DERs under the Plan with respect to the deferred Performance
Shares. Each DER will be expressed as a specific dollar amount (a "Dollar
Amount") equal to the dollar amount of dividends paid on an actual Share on a
specific date (a "Dividend Date") during the deferral period multiplied by the
number of Performance Shares still deferred by the Participant as of the
Dividend Date. The Committee will apply the Dollar Amount to "purchase" notional
shares (on which DERs thereafter will also be awarded) at the closing price of a
Share on the Dividend Date. Notional shares deemed purchased with DERs hereunder
may be whole or fractional shares. DERs expressed as a Dollar Amount will
continue to be applied to "purchase" notional shares on Dividend Dates until all
of the Participant's deferred Performance Shares are delivered to the
Participant (or to his or her beneficiary(ies)), as elected in his or her
deferral election agreement.

         The Trust shall establish a bookkeeping account (the "DER Account") for
each such Participant and credit to such account the number of whole and
fractional notional shares deemed purchased with the Dollar Amounts. A
Participant's DER Account shall be 100% vested at all times. The Participant's
notional shares shall be subject to the adjustments described in Section 8. All
whole notional shares credited to a Participant's DER Account shall be replaced
by issued Shares on a one-to-one basis, and the fractional notional shares
credited to a Participant's DER Account shall be aggregated and replaced by
issued Shares and with cash based on the closing price of a Share on the
replacement date, and delivered to the Participant (or to his or her
beneficiary(ies)) on, or as soon as administratively practicable after, the date
the associated Performance Shares are delivered to the Participant pursuant to
his or her deferral election agreement.

         A Participant's deferral election agreement must be submitted to the
Committee no later than June 30, 2008 in order to be effective; otherwise,
Performance Shares deliverable to the Participant, if any, will be delivered on,
or as soon as administratively practicable after, February 15, 2009. If deferred
Performance Shares are to be delivered to a Participant who is a "specified
employee," as defined in section 409A(a)(2)(B)(i) of the Code, upon his or her
separation from service from the Trust's controlled group of entities, the Trust
shall issue and deliver such deferred Performance Shares on, or as soon as

                                      -6-



administratively practicable after, the earlier of (i) the date that is six
months after the date of his or her separation from service and (ii) his or her
death. A deferral election agreement shall be substantially in the form set
forth in Appendix D attached hereto. The Committee shall administer the delivery
of Performance Shares (and Shares and cash deliverable with respect to DERs
awarded thereon) under an election made pursuant to this subsection (e) and the
underlying deferral election agreement in accordance with section 409A of the
Code and regulations and other guidance issued thereunder.

         5. Beneficiary Designation

          (a) Each Participant shall designate the person(s) as the
     beneficiary(ies) to whom the Participant's Performance Shares shall be
     delivered in the event of the Participant's death prior to the delivery of
     the Performance Shares to him or her. Each beneficiary designation shall be
     substantially in the form set forth in Appendix B attached hereto and shall
     be effective only when filed with the Committee during the Participant's
     lifetime.

          (b) Any beneficiary designation may be changed by a Participant
     without the consent of any previously designated beneficiary or any other
     person by the filing of a new beneficiary designation with the Committee.
     The filing of a new beneficiary designation shall cancel all beneficiary
     designations previously filed.

          (c) If any Participant fails to designate a beneficiary in the manner
     provided above, or if the beneficiary designated by a Participant
     predeceases the Participant, the Committee shall direct such Participant's
     Performance Shares to be delivered to the Participant's surviving spouse
     or, if the Participant has no surviving spouse, then to the Participant's
     estate.

         6. Delivery to Guardian. If Shares are issuable under this Program to a
minor, a person declared incompetent or a person incapable of handling the
disposition of property, the Committee may direct the delivery of the
Performance Shares to the guardian, legal representative or person having the
care and custody of the minor, incompetent or incapable person. The Committee
may require proof of incompetency, minority, incapacity or guardianship as the
Committee may deem appropriate prior to the delivery. The delivery shall
completely discharge the Committee, the Trustees, and the Employer from all
liability with respect to the Performance Shares delivered.

         7. Source of Shares. This Program shall be unfunded, and the delivery
of Performance Shares shall be pursuant to the Plan. Each Participant and
beneficiary shall be a general and unsecured creditor of the Employer to the
extent of the Performance Shares determined hereunder, and the Participant shall
have no right, title or interest in any specific asset that the Employer may set
aside, earmark or identify as for the delivery of Performance Shares under the
Program. The Employer's obligation under the Program shall be merely that of an
unfunded and unsecured promise to deliver Performance Shares in the future,
provided the Corporate Goal is met.

         8. Capital Adjustments. Calculations required under the Program and the
number of Shares that may be delivered under the Program shall be adjusted, as
may be deemed appropriate by the Committee, to reflect any increase or decrease
in the number of issued Shares resulting from a subdivision (share-split),
consolidation (reverse split), share dividend, or other change in the
capitalization of the Trust during the Measurement Period.

                                      -7-



         9. Administration. This Program shall be administered by the Committee
pursuant to the powers granted to it in Section 3 of the Plan.

         10. Amendment and Termination. The Committee reserves the right to
amend the Program, by written resolution, at any time and from time to time in
any fashion, provided any such amendment does not conflict with the terms of the
Plan, and to terminate it at will. However, no amendment or termination of the
Program shall adversely affect any Award Agreement already issued under the
Program without the written consent of the affected Participant(s).

         11. Headings. The headings of the Sections and subsections of the
Program are for reference only. In the event of a conflict between a heading and
the content of a Section or subsection, the content of the Section or subsection
shall control.

         12. Incorporation of Plan by Reference. Because the Program is
established under the Plan in order to provide for, and determine the terms and
conditions of, the granting of certain Awards thereunder, the terms and
conditions of the Plan are hereby incorporated by reference and made a part of
this Program. If any terms of the Program conflict with the terms of the Plan,
the terms of the Plan shall control.

         IN WITNESS WHEREOF, the Executive Compensation and Human Resources

                 (Established Under the Pennsylvania Real Estate
                  Investment Trust 2003 Equity Incentive Plan)

                                   EXAMPLES*

Example 1. When Threshold Is a 12% Share Increase

A and B are participants in the Pennsylvania Real Estate Investment Trust
2005-2008 Outperformance Program (the "Program"). As of January 1, 2005,
Pennsylvania Real Estate Investment Trust (the "Trust") has 40,500,000
outstanding shares, calculated as follows:

         Outstanding Trust Shares                  36,000,000
         Outstanding Partnership Units            + 4,500,000
         -----------------------------            -----------
         Total "Shares" Outstanding                40,500,000

For the 4-year period from January 1, 2005 through December 31, 2008 (the
"Measurement Period"), dividends equal $9 per share. The average closing price
per share for the 20 trading days ending January 1, 2005 is $40 and the average
closing price per share for the 20 trading days ending December 31, 2008 is $66.

Total Return to Shareholders ("TRS") on one share over the Measurement Period is
calculated as follows:

       12/31/08 Value of One Share                               $66
       + Dividends over Measurement Period on One Share          + 9
       - 1/1/05 Value of One Share                              - 40
       ---------------------------                              ----
       TRS                                                       $35

In order for the participants in the Program to receive an award of "Performance
Shares" in 2009, the Trust must have TRS for the Measurement Period that exceeds
the greater of (i) an amount equal to the increase in the value of a share over
the Measurement Period if it appreciates at a 12% annual rate compounded as of
the last day of each calendar year ending in the Measurement Period ("12% Share
Increase"), or (ii) an amount equal to the increase in the value of a share over
the Measurement Period if it appreciates at a rate equal to 115% of the total
return of the Morgan Stanley REIT Index (the "MSRI") over the Measurement Period
("115% MSRI Share Increase"). In this example, a 12% Share Increase is greater
than a 115% MSRI Share Increase.

- ----------
*    THE EXAMPLES SET FORTH IN THIS APPENDIX C DO NOT SHOW THE FULL CALCULATION
     OF "TRS" (AS DEFINED BELOW) BECAUSE, FOR EASE OF EXPLANATION, THEY DO NOT
     REFLECT THAT EACH CASH DIVIDEND PAID DURING THE "MEASUREMENT PERIOD" (AS
     DEFINED BELOW) IS DEEMED TO BE REINVESTED IN A FRACTIONAL NOTIONAL SHARE OF
     THE "TRUST" (AS DEFINED BELOW). WHEN ACTUALLY CALCULATING TRS, EACH CASH
     DIVIDEND WILL GENERALLY BE DEEMED TO BE REINVESTED IN A FRACTIONAL NOTIONAL
     SHARE, AS SET FORTH IN SECTION 4(B)(6) OF THE "PROGRAM" (AS DEFINED BELOW).


                                      C-1



A 12% Share Increase equals the initial value of the share ($40) times
57.3519%(1) or $22.9408. Thus, TRS for the Measurement Period of $35 exceeds a
12% Share Increase and participants are entitled to receive Performance Shares
under the Program.

A share that appreciates at an annual compound rate of 16% for 4 years ("16%
Share Increase") equals the initial value of the share ($40) times 81.0639%(2)
or $32.4256. Thus, TRS for the Measurement Period of $35 also exceeds a 16%
Share Increase.

The bonus pool from which the awards to the participants are determined is
calculated as follows:

Because TRS for the Measurement Period exceeds both a 12% Share Increase and a
16% Share Increase, the calculation of the bonus pool equals (i) 4.5% times TRS
for the Measurement Period that is greater than a 12% Share Increase but that is
not greater than a 16% Share Increase, plus (ii) 6.5% of TRS for the Measurement
Period that is greater than a 16% Share Increase, the sum times (iii) 40,500,000
shares (the number of outstanding shares did not change during the Measurement
Period):

         4.5% x ($32.4256 - $22.9408) = $0.4268
                            +
         6.5% x ($35.0000 - $32.4256) = $0.1673
                                        -------
                                        $0.5941
                                        =======

         BONUS POOL AMOUNT = $0.5941 x 40,500,000 shares = $24,061,050(3)

A is entitled to 15% of the bonus pool or 15% x $24,061,050 = $3,609,157.50.
This amount is converted to shares by dividing it by the average closing price
of a share for the 20 trading days ending December 31, 2008 and rounding down to
the nearest whole share. As stated above, that price is $66. Thus, A will be
awarded 54,684 Performance Shares ($3,609,157.50 / $66/share = 54,684 shares).

B is entitled to 12.5% of the bonus pool or 12.5% x $24,061,050 = $3,007,631.25.
This amount is converted to shares by dividing it by the average closing price
of a share of $66 and rounding down to the nearest whole share. Thus, B will be
awarded 45,570 Performance Shares ($3,007,631.25 / $66/share = 45,570 shares).


- ----------

(1)  The appreciation in X, compounded at 12% annually for 4 years, is 57.3519%
     of X.

(2)  The appreciation in X, compounded at 16% annually for 4 years, is 81.0639%
     of X.

(3)  In this example, there are the same number of outstanding shares on
     December 31, 2008 as there were on January 1, 2005. Their value determined
     as of December 31, 2008 is $66 x 40,500,000 shares = $2,673,000,000. The
     cap on the bonus pool is one percent of that value or $26,730,000. The
     bonus pool amount is less than that cap.

                                      C-2


Example 2. When Threshold Is a 115% MSRI Share Increase

A and B are participants in the Program. All of the facts in Example 1 are
unchanged in this example except that a 115% MSRI Share Increase exceeds a 12%
Share Increase. The MSRI was 600 as of January 1, 2005 and 960 as of December
31, 2008.

In order for the participants in the Program to receive an award of Performance
Shares in 2009, the Trust must have TRS for the Measurement Period that exceeds
the greater of (i) a 12% Share Increase or (ii) a 115% MSRI Share Increase, both
for the Measurement Period.

As calculated in Example 1, a 12% Share Increase equals $22.9408. The percentage
increase in the MSRI is 60% (the 360-point increase in the MSRI divided by its
600-point level as of January 1, 2005 equals 60%). 115% of the percentage
increase in the MSRI during the Measurement Period is 60% x 115% = 69%. The
initial share price of $40 is multiplied by 69% to obtain a 115% MSRI Share
Increase of $27.60. Since a 115% MSRI Share Increase is greater than a 12% Share
Increase, the Trust must have TRS of greater than $27.60 for participants to
receive an allocation of Performance Shares.

The Trust's TRS on one share of $35 exceeds $27.60, and therefore participants
will receive an allocation of Performance Shares.

The bonus pool from which the awards to the participants are determined is
calculated as follows:

The bonus pool equals (i) 4.5% times TRS for the Measurement Period that is
greater than a 115% MSRI Share Increase but that is not greater than a 16% Share
Increase and (ii) 6.5% times TRS for the Measurement Period that is greater than
a 16% Share Increase, the sum times (iii) 40,500,000 shares:

         4.5% x ($32.4256-$27.6000) = $0.2172
                  +
         6.5% x ($35.0000-$32.4256) = $0.1673
                                      -------
                                      $0.3845

         BONUS POOL AMOUNT = $0.3845 x 40,500,000 shares = $15,572,250(4)

A is entitled to 15% of the bonus pool or 15% x $15,572,250 = $2,335,837.50.
This amount is converted to shares by dividing it by the December 31, 2008 value
of one share of $66 and rounding down to the nearest whole share. Thus, A will
be awarded 35,391 Performance Shares ($2,335,837.50 / $66/share = 35,391
shares).

B is entitled to 12.5% of the bonus pool or 12.5% x $15,572,250 = $1,946,531.20.
This amount is converted to shares by dividing it by the December 31, 2008 value
of one share of $66 and rounding down to the nearest whole share. Thus, B will
be awarded 29,492 Performance Shares ($1,946,531.20 / $66/share = 29,492
shares).

Example 3. When Change in Control Occurs

A and B are participants in the Program. The Total "Shares" Outstanding and the
value of one share at January 1, 2005 are the same as in Examples 1 and 2.
However, a change in control occurs when the Trust's shareholders approve a
business combination on August 1, 2007. The closing date/effective date of the
business combination is December 31, 2007 and the business combination does
close/become effective on that date after dividends of $7/share have been
declared from January 1, 2005 through December 31, 2007. Because of the change
in control, the Measurement Period will end on December 31, 2007 rather than
December 31, 2008.

The final price per share agreed upon by the parties to the business combination
is $55.

TRS over the Measurement Period on one share is calculated as follows:

      12/31/07 Value of One Share as Agreed upon by Parties
      to Business Combination                                   $55
      + Dividends over Measurement Period on One Share          + 7
      - 1/1/05 Value of One Share                              - 40
      ---------------------------                              ----
      TRS                                                       $22

In order for the participants in the Program to receive an award of Performance
Shares in 2008, the Trust must have TRS for the Measurement Period that exceeds
the greater of (i) the 12% Share Increase or (ii) the 115% MSRI Share Increase,
both for the Measurement Period.

The 12% Share Increase equals the initial value of a share ($40) times
40.4928%(5) or $16.1971. For this example, the MSRI was 600 at January 1, 2005
and 780 at December 31, 2007. The percentage increase in the MSRI is 30% (the
180-point increase in the MSRI divided by its 600-point level as of January 1,
2005). 115% MSRI is therefore 30% times 115% = 34.5%. The initial share price of
$40 is multiplied by 34.5% to obtain a 115% MSRI Share Increase of $13.80, which
is less than the 12% Share Increase. Thus, TRS must be equal to or greater than
the 12% Share Increase of $16.1971. Because TRS is $22, participants are
entitled to a performance award under the Program.

The 16% Share Increase equals the initial value of a share ($40) times
56.0896%(6) or $22.4358. As TRS does not exceed that amount, the bonus pool
equals 4.5% times TRS for the Measurement Period that exceeds the 12% Share
Increase times 40,500,000 shares:


         4.5% x ($22 - $16.1971) = $0.2611

         BONUS POOL AMOUNT = $0.2611 x 40.500,000 shares = $10,574,550(7)

- ----------

(5)  The appreciation in X compounded at 12% annually for 3 years, is 40.4928%
     of X.

(6)  The appreciation in X compounded at 16% annually for 3 years, is 56.0896%
     of X.

(7)  In this example, there are the same number of outstanding shares on
     December 31, 2007 as there were on January 1, 2005. Their value as agreed
     upon by the parties to the business combination that closes/becomes
     effective on December 31, 2007 is $55 x 40,500,000 shares = $2,227,500,000.
     The cap on the bonus pool is one percent of that value or $22,275,000. The
     bonus pool amount is less than that cap.


                                      C-4



A is entitled to 15% of the bonus pool or 15% x $10,574,550 = $1,586,182.50.
This amount is converted to shares by dividing it by the value of one share as
agreed upon by the parties to the business combination that closes/becomes
effective on December 31, 2007, and rounding down to the nearest whole share. As
stated above, that price is $55. Thus, A will be awarded 28,839 Performance
Shares ($1,586,182.50 / $55/share = 28,839 shares).

B is entitled to 12.5% of the bonus pool or 12.5% x $10,574,550 = $1,321,818.75.
This amount is converted to shares by dividing it by the value of one share of
$55 and rounding down to the nearest whole share. B will be awarded 24,033
Performance Shares ($1,321,818.75 / $55/share = 24,033 shares).

Example 4. When Buy Back and Public Offering Occur

A and B are participants in the Program. As in all prior examples, the Trust has
40,500,000 outstanding shares on January 1, 2005. The Trust buys back 5,000,000
shares on July 1, 2005, and then sells 10,000,000 newly issued shares on July 1,
2007 through a public offering which does not result in a change in control.

For the 4-year Measurement Period, dividends equal $9 per share. The average
closing price per share for the 20 trading days ending January 1, 2005 is $40
and the average closing price per share for the 20 trading days ending December
31, 2008 is $68.

The TRS over the Measurement Period on one share is calculated as follows:

In order for the participants in the Program to receive an award of Performance
Shares in 2009, TRS for the Measurement Period must exceed the greater of (i)
the 12% Share Increase or (ii) the 115% MSRI Share Increase. In this example,
the 12% Share Increase is greater than the 115% MSRI Share Increase.

The 12% Share Increase is $22.9408 ($40 times 57.3519%). Thus TRS for the
Measurement Period of $37 exceeds a 12% Share Increase and participants are
entitled to receive Performance Shares under the Program.


                                      C-5



The TRS of $37 also exceeds the 16% Share Increase of $32.4256 ($40 times
81.0639%).

Because TRS for the Measurement Period exceeds both the 12% and 16% Share
Increases, the calculation of the bonus pool equals (i) 4.5% times TRS for the
Measurement Period that is greater than a 12% Share Increase but that is not
greater than a 16% Share Increase, plus (ii) 6.5% of TRS for the Measurement
Period that is greater than a 16% Share Increase, the sum times the number of
shares for the Measurement Period.

As in example 1, 4.5% times TRS in excess of the 12% Share Increase but not
greater than the 16% Share Increase is $0.4268. In this example, 6.5% of the TRS
that exceeds the 16% Share Increase is $0.2973 (6.5% x ($37.00 - 32.4256)). The
sum of those two amounts equals $0.7241.

Because the number of shares did not remain constant throughout the Measurement
Period, the number of shares used to calculate the bonus pool amount must be
weighted to reflect the fluctuation. In this example, only two changes occurred
during the Measurement Period: the Trust's buy back of 5,000,000 shares on July
1, 2005 and the Trust's sale of 10,000,000 shares on July 1, 2007 through a
public offering.

The weighted number of shares for the determination of the bonus pool is
calculated as follows:

The number of outstanding shares at the beginning of the Measurement Period on
January 1, 2005 is multiplied by the number of days during which there were
40,500,000 outstanding shares (January 1, 2005 through June 30, 2005) and then
divided by the total number of days in the entire Measurement Period:

              40,500,000 shares x   181 days = 5,017,453.79 shares
                                  ----------
                                  1,461 days

The buy back on July 1, 2005 reduced the number of outstanding shares to
35,500,000 shares. This number is multiplied by the number of days from July 1,
2005 through June 30, 2007, the day before the sale of 10,000,000 shares, and
then divided by the total number of days in the entire Measurement Period:

              35,500,000 shares x   730 days = 17,737,850.76 shares
                                  ----------
                                  1,461 days

The sale of 10,000,000 shares on July 1, 2007 increased the number of shares to
45,500,000. This number is multiplied by the number of days from July 1, 2007
through the end of the Measurement Period (December 31, 2008) and then divided
by the total number of days in the Measurement Period (2008 is a leap year):

              45,500,000 shares x   550 days = 17,128,678.97 shares
                                  ----------
                                  1,461 days


                                      C-6


The number of shares to be used to calculate the bonus pool is the sum of these
three numbers or 39,883,983.52. This number is multiplied by $0.7241 to
determine the bonus pool amount of $28,879,992.46.(8)

A is entitled to 15% of the bonus pool or 15% x $28,879,992.46 = $4,331,998.87.
This amount is converted to shares by dividing it by the average closing price
of a share for the 20 trading days ending December 31, 2008 ($68) and rounding
down to the nearest whole share. Thus A will be awarded 63,705 shares
($4,331,998.87 / $68/share = 63,705 shares).

B is entitled to 12.5% of the bonus pool or 12.5% x $28,879,992.46 =
$3,609,999.06. This amount is converted to shares by dividing it by the average
closing price of a share of $68 and rounding down to the nearest whole share.
Thus, B will be awarded 53,088 shares ($3,609,999.06 / $68/share = 53,088
shares).



- ----------

(8)  The actual number of outstanding shares on December 31, 2008 is 45,500,000.
     The total value of the outstanding shares is determined by multiplying that
     number by $68, which results in $3,094,000,000. The cap on the bonus pool
     is one percent of that value or $30,940,000. The bonus pool amount is less
     than that cap.

                        2005-2008 OUTPERFORMANCE PROGRAM

                          DEFERRAL ELECTION AGREEMENT*
                          ----------------------------

         The Pennsylvania Real Estate Investment Trust 2005-2008 Outperformance
Program (Established Under the Pennsylvania Real Estate Investment Trust 2003
Equity Incentive Plan), effective as of January 1, 2005 (the "Program"),
provides a select group of management or highly compensated employees with the
ability to defer a portion of their compensation earned under the Program. The
purpose of this Deferral Election Agreement is to allow you to defer the
delivery of all or a portion of the Performance Shares (and Shares deliverable
with respect to dividend equivalent rights ("DERs") awarded thereon) that are
otherwise deliverable to you under the Program until one of the events selected
below occurs.

AFTER YOU SIGN THIS DEFERRAL ELECTION AGREEMENT AND IT IS ACCEPTED BY
PENNSYLVANIA REAL ESTATE INVESTMENT TRUST (THE "TRUST") YOU MAY NOT REVOKE IT
AFTER JUNE 30, 2008. IF YOU DECIDE SUBSEQUENTLY TO CHOOSE A LATER DELIVERY DATE,
YOU MUST SUBMIT A NEW DEFERRAL ELECTION AGREEMENT AT LEAST 12 MONTHS PRIOR TO
YOUR ORIGINAL DELIVERY DATE AND YOUR NEW DELIVERY DATE MUST BE AT LEAST FIVE
YEARS AFTER YOUR ORIGINAL DELIVERY DATE. YOU MAY NOT, UNDER ANY CIRCUMSTANCES,
ACCELERATE THE DELIVERY OF YOUR PERFORMANCE SHARES (OR THE SHARES DELIVERABLE
WITH RESPECT TO ANY DERS AWARDED THEREON) AFTER THIS ELECTION AGREEMENT HAS
BECOME EFFECTIVE.

You need only complete this Deferral Election Agreement if you wish to defer the
delivery of Performance Shares (and Shares deliverable with respect to DERs
awarded thereon) that become deliverable to you under the Program. Capitalized
terms in this Deferral Election Agreement are defined in the Program.

1.   Participation Election

     ____ I hereby elect to defer under the terms of the Program the delivery of
          ______% [INSERT ANY WHOLE PERCENTAGE FROM ONE TO 100 PERCENT,
          INCLUSIVE] of the Performance Shares that may become deliverable to me
          under the Program.


- ----------

*    Because of the complexities involved in the application of federal, state
     and local tax laws to specific circumstances and the uncertainties as to
     possible future changes in the tax laws, you should consult your personal
     tax advisor regarding your own situation before completing this Deferral
     Election Agreement.

Shares set forth above (and the Shares deliverable with respect to DERs awarded
thereon) that may become deliverable to me under the Program upon the following
event [CHECK ONLY ONE BOX]:

____ (A) Upon, or as soon as administratively practicable after, my separation
     from service from the Trust's controlled group of entities (six months
     after such separation from service if I am a "specified employee" at that
     time - see Section 4(e) of the Program).

____ (B) On, or as soon as administratively practicable after, the following
     date: ___________ __, 20__.

     Code. See the footnote on the previous page regarding consulting with your
     own tax advisor before completing this Deferral Election Agreement.)

4. Death

If my death occurs before all of the Performance Shares (and Shares deliverable
with respect to DERs awarded thereon) are delivered to me, such Performance
Shares and Shares shall be delivered in a single sum to my beneficiary(ies)
