                   11% NON-CONVERTIBLE SENIOR PREFERRED SHARES

                    PENNSYLVANIA REAL ESTATE INVESTMENT TRUST

 ______________________________________________________________________________


                  Pennsylvania Real Estate Investment Trust, a business trust
organized and existing under the laws of the Commonwealth of Pennsylvania
("PREIT"), hereby certifies that, pursuant to the authority conferred upon the
Board of Trustees of PREIT (the "Board of Trustees") by the Trust Agreement As
Amended and Restated December 16, 1997 (the "Trust Agreement") and in accordance
with 15 Pa. C.S. Chapter 95, the Board of Trustees on May 13, 2003 duly adopted
the following resolution, which resolution remains in full force and effect as
of the date hereof:

                  RESOLVED, that, subject to and effective upon the Effective
Time of the Merger (as such terms are defined in that certain Agreement and Plan
of Merger dated as of May 13, 2003 by and among PREIT, PREIT Associates, L.P.,
Crown American Realty Trust and Crown American Properties, L.P.) pursuant to the
authority vested in the Board of Trustees and in accordance with the provisions
of the Trust Agreement, there is hereby created and authorized a series of
preferred shares of PREIT, and the rights, preferences, privileges,
qualifications, limitations and restrictions of such series are as follows:

                   11% NON-CONVERTIBLE SENIOR PREFERRED SHARES

                  Section 1 Number of Shares and Designation. This series of
preferred shares shall be designated as 11% Non-Convertible Senior Preferred
Shares (the "Senior Preferred Shares") and the number of shares which shall
constitute such series shall be 2,475,000 shares, par value $.01 per share,
which number may be decreased (but not below the number thereof then
outstanding) from time to time by the Board of Trustees.

                  Section 2 Dividend Rights.

                  (a) Holders of the Senior Preferred Shares shall be entitled
         to receive, when, as and if declared by the Board of Trustees, out of
         funds legally available for the payment of dividends, cumulative,
         preferential cash dividends in an amount per Senior Preferred Share
         equal to $5.50 per annum plus the amount of any Additional Dividends
         (defined below) (except that the initial dividend shall accrue and be
         payable as if the December 2003 quarterly dividend period, as described
         below, were a full quarterly dividend period, regardless of the date of
         original issuance of the Senior Preferred Shares). Each such dividend
         shall be payable to holders of record as they appear on the share
         transfer books of PREIT on such record dates as provided below.



                                                                     Exhibit 4.1

                  (b) Dividends with respect to the Senior Preferred Shares will
         be cumulative and will be payable quarterly (each quarterly period, a
         "Dividend Period") in arrears in March, June, September and December
         (on the same dates as dividends on Common Shares, par value $1.00 per
         share (the "Common Shares"), beginning with the dividend payment for
         the December 2003 Dividend Period (each, a "Preferred Dividend Payment
         Date"). Any dividend payable on the Senior Preferred Shares for any
         partial dividend period after the initial dividend period will be
         computed on the basis of a 360-day year consisting of twelve 30-day
         months. Dividends payable on the Senior Preferred Shares for each full
         Dividend Period will be computed by dividing the annual dividend rate
         by four. The initial dividend payable on the Senior Preferred Shares
         will be with respect to the December 2003 Dividend Period and will
         accrue for the full December 2003 Dividend Period and shall be equal to
         the full quarterly dividend amount of $1.375 per share. Dividends will
         be payable to holders of record as they appear in the share records of
         PREIT at the close of business on the applicable record date, which
         will be the first day of the calendar month in which the applicable
         Preferred Dividend Payment Date falls or such other date designated by
         the Board of Trustees for the payment of dividends that is no more than
         thirty (30) nor less than ten (10) days prior to such Preferred
         Dividend Payment Date (each, a "Preferred Dividend Record Date").

                  (c) No dividends on the Senior Preferred Shares will be
         declared by the Board of Trustees or paid or set apart for payment by
         PREIT at such time as, and to the extent that, the terms and provisions
         of any agreement of PREIT, including any agreement relating to its
         indebtedness, or any provisions of the Trust Agreement relating to any
         series of preferred shares ranking senior to the Senior Preferred
         Shares as to dividends, prohibit such declaration, payment or setting
         apart for payment or provide that such declaration, payment or setting
         apart for payment would constitute a breach thereof or a default
         thereunder, or if such declaration or payment will be prohibited by
         law. Notwithstanding the foregoing, dividends on the Senior Preferred
         Shares will accrue whether or not PREIT has earnings, whether or not
         there are funds legally available for the payment of such dividends and
         whether or not such dividends are declared. Holders of the Senior
         Preferred Shares will not be entitled to any dividends or distributions
         in excess of full cumulative dividends as described above.

                  (d) If any Senior Preferred Shares are outstanding, no full
         dividends will be declared or paid or set apart for payment on the
         capital shares of PREIT of any other series ranking, as to dividends,
         on a parity with or junior to the Senior Preferred Shares for any
         period unless full cumulative dividends (including any Additional
         Dividends) have been or contemporaneously are declared and paid or
         declared and a sum sufficient for the payment thereof set apart for
         such payment on the Senior Preferred Shares for all past Dividend
         Periods and the then current Dividend Period. When dividends are not
         paid in full (or a sum sufficient for such full payment is not so set
         apart) upon the Senior Preferred Shares and any series of preferred
         shares ranking on a parity as to dividends with the Senior Preferred
         Shares, all dividends declared upon the Senior Preferred Shares and any
         series of preferred shares ranking on a parity as to dividends with the
         Senior Preferred Shares will be declared pro rata so that the amount of
         dividends declared per Senior Preferred Share and such other series of
         preferred shares will in all cases bear to each other the same ratio
         that accrued and unpaid dividends per Senior Preferred Share and such
         other series of preferred shares bear to each other. No interest, or
         sum of money in lieu of interest, will be payable in respect of any
         dividend payment or payments on the Senior Preferred Shares which may
         be in arrears.



                                                                     Exhibit 4.1

                  (e) Except as provided in the immediately preceding paragraph,
         unless full cumulative dividends (including any Additional Dividends)
         on the Senior Preferred Shares have been or contemporaneously are
         declared and paid or declared and a sum sufficient for the payment
         thereof set apart for payment for all past Dividend Periods and the
         then current Dividend Period, no dividends (other than distributions
         payable in Common Shares or other capital shares ranking junior to the
         Senior Preferred Shares as to dividends and upon liquidation,
         dissolution or winding up of PREIT) will be declared or paid or set
         aside for payment, and no other distribution will be declared or made,
         upon the Common Shares or any other capital shares of PREIT ranking
         junior to or on a parity with the Senior Preferred Shares as to
         dividends, nor will any Common Shares or any other capital shares of
         PREIT ranking junior to or on a parity with the Senior Preferred Shares
         as to dividends or upon liquidation, dissolution or winding up of PREIT
         be redeemed, purchased or otherwise acquired for any consideration (or
         any moneys be paid to or made available for a sinking fund for the
         redemption of any such shares) by PREIT (except by conversion into or
         exchange for other capital shares of PREIT ranking junior to the Senior
         Preferred Shares as to dividends and upon liquidation, dissolution and
         winding up).

                  (f) Any dividend payment made on Senior Preferred Shares shall
         first be credited against the earliest accrued but unpaid dividend due
         with respect to the Senior Preferred Shares which remains payable.

                  (g) The Holders of the Senior Preferred Shares may be eligible
         to receive additional dividends ("Additional Dividends") from time to
         time in the event that PREIT exceeds the defined leverage ratio
         requirement in Clause 2(g)(i) below.

                           (i) Additional Dividends in the amounts described in
                  this Section 2(g) shall be paid quarterly to the holders of
                  the Senior Preferred Shares if PREIT's "Total Debt" (defined
                  below) exceeds the product of 6.5 times "EBITDA" (defined
                  below) (the "Leverage Ratio") without the consent of the
                  holders of at least 50% of the Senior Preferred Shares
                  outstanding at that time. Holders who consent to a waiver of
                  such restriction will be paid a consent fee amount to be
                  negotiated at the time of such consent.



                                                                     Exhibit 4.1

                           (ii) "Total Debt" means PREIT's consolidated debt
                  from income producing properties determined as a weighted
                  average based on the number of days such debt was outstanding.
                  "EBITDA" means PREIT's consolidated earnings before interest,
                  taxes, depreciation and amortization. Total Debt, EBITDA and
                  the Leverage Ratio will be calculated quarterly, on a trailing
                  four quarters basis, and PREIT's independent auditors will
                  audit or perform agreed upon procedures on the calculation
                  commencing with the quarter ending December 31, 2003. PREIT
                  will promptly deliver copies of such calculations, together
                  with the related report of independent accountants to all
                  holders of the Senior Preferred Shares.

                           (iii) If required to be paid, Additional Dividends
                  will be for an amount per Senior Preferred Share equal to
                  0.25% of the Preferred Liquidation Preference Amount (defined
                  below) on an annualized basis for the first quarter with
                  respect to which an Additional Dividend is due. For each
                  quarter thereafter that PREIT continues to exceed the
                  permitted Leverage Ratio, the Additional Dividend will
                  increase by an amount per Senior Preferred Share equal to an
                  additional 0.25% of the Preferred Liquidation Preference
                  Amount (defined below) on an annualized basis. However, the
                  maximum total dividend on the Senior Preferred Shares,
                  including any Additional Dividends, will not at any time
                  exceed 13.00% of the Preferred Liquidation Preference Amount
                  per annum.

                           (iv) If Additional Dividends are payable at any time
                  and thereafter the Leverage Ratio for any quarter is 6.5 or
                  less, the requirement to pay Additional Dividends will
                  terminate beginning with the quarter in which compliance is
                  achieved. Subsequent non-compliance, however, will result in
                  the Additional Dividends again becoming due commencing with
                  the quarter in which the Leverage Ratio is exceeded,
                  calculated as described above in an amount per Senior
                  Preferred Share initially equal to 0.25% of the Preferred
                  Liquidation Preference Amount on an annualized basis and
                  increasing thereafter in quarterly increments as described in
                  clause (iii) above.

                  Section 3 Distribution Upon Liquidation, Dissolution or
Winding Up.

                  (a) In the event of any liquidation, dissolution or winding up
         of PREIT, subject to the prior rights of any series of capital shares
         of PREIT ranking senior to the Senior Preferred Shares, the holders of
         Senior Preferred Shares will be entitled to be paid out of the assets
         of PREIT legally available for distribution to its shareholders a
         liquidation preference equal to the sum of $50.00 per Senior Preferred
         Share plus an amount equal to any accrued and unpaid dividends thereon
         (including any Additional Dividends and whether or not earned or
         declared) to the date of payment (the "Preferred Liquidation Preference
         Amount"), before any distribution of assets is made to holders of
         Common Shares or any other capital shares that rank junior to the
         Senior Preferred Shares as to liquidation rights. After payment of the
         full amount of the liquidating distributions to which they are
         entitled, the holders of the Senior Preferred Shares will have no right
         or claim to any of the remaining assets of PREIT.



                                                                     Exhibit 4.1

                  (b) In the event that, upon any such voluntary or involuntary
         liquidation, dissolution or winding up of PREIT, the remaining legally
         available assets of PREIT are insufficient to pay the Preferred
         Liquidation Preference Amount on all outstanding Senior Preferred
         Shares and the corresponding amounts payable on all shares of other
         classes or series of capital shares of PREIT ranking on a parity with
         the Senior Preferred Shares in the distribution of assets upon
         liquidation, dissolution or winding up of PREIT, then the holders of
         the Senior Preferred Shares and all other such classes or series of
         capital shares will share ratably in any such distribution of assets,
         or the proceeds thereof, in proportion to the full liquidating
         distributions to which they would otherwise be respectively entitled.

                  (c) After payment of any liquidating distributions has been
         made in full to all holders of Senior Preferred Shares, the remaining
         assets of PREIT will be distributed among the holders of any other
         classes or series of capital shares ranking junior to Senior Preferred
         Shares upon liquidation, dissolution or winding up of PREIT, according
         to their respective rights and preferences and in each case according
         to their respective number of shares, and the holders of Senior
         Preferred Shares shall not be entitled to share therein.

                  (d) The consolidation or merger of PREIT with or into any
         other corporation or other entity, the consolidation or merger of
         another corporation or other entity with or into PREIT, and the sale,
         lease, transfer or conveyance of all or any part of the property or
         business of PREIT, will not be deemed to constitute a liquidation,
         dissolution or winding up of PREIT for these purposes.

                  Section 4 Redemption by PREIT.

                  (a) The Senior Preferred Shares will not be redeemable prior
         to July 31, 2007, except under certain limited circumstances to
         preserve PREIT's status as a REIT. On and after July 31, 2007, PREIT,
         at its option (to the extent PREIT has funds legally available
         therefor) upon not less than 30 nor more than 60 days written notice,
         may redeem the Senior Preferred Shares, in whole or in part, at any
         time or from time to time, for cash at the redemption price per share
         as set forth in the table below, plus all accrued and unpaid dividends,
         if any, thereon (whether or not earned or declared) to the date fixed
         for redemption (the "Redemption Date").



                                                                     Exhibit 4.1

                                                         Redemption Price
                Redemption Period                   Per Senior Preferred Share
                -----------------                   --------------------------

         July 31, 2007 through July 30, 2009                 $52.50
         July 31, 2009 through July 30, 2010                 $51.50
         On or after July 31, 2010                           $50.00

                  (b) Notwithstanding the foregoing, unless full cumulative
         dividends on all Senior Preferred Shares have been or contemporaneously
         are declared and paid or declared and a sum sufficient for the payment
         thereof set apart for payment for all past Dividend Periods and the
         then current Dividend Period, no Senior Preferred Shares will be
         redeemed unless all outstanding Senior Preferred Shares are
         simultaneously redeemed; provided, however, that the foregoing will not
         prevent the purchase or acquisition of Senior Preferred Shares pursuant
         to a purchase or exchange offer made on the same terms to holders of
         all outstanding Senior Preferred Shares, and unless full cumulative
         dividends on all outstanding Senior Preferred Shares have been or
         contemporaneously are declared and paid or declared and a sum
         sufficient for the payment thereof set apart for payment for all past
         Dividend Periods and the then current Dividend Period, PREIT will not
         purchase or otherwise acquire directly or indirectly through a
         subsidiary or otherwise, any Senior Preferred Shares.

                  (c) If fewer than all of the outstanding Senior Preferred
         Shares are to be redeemed, the number of shares to be redeemed will be
         determined by PREIT and such shares may be redeemed pro rata from the
         holders of record of such shares in proportion to the number of such
         shares held by such holders (as nearly as may be practicable without
         creating fractional Senior Preferred Shares) or any other equitable
         method determined by PREIT.

                  (d) Notice of redemption will be given by publication in a
         newspaper of general circulation in the City of New York, such
         publication to be made once a week for two successive weeks commencing
         not less than 30 nor more than 60 days prior to the Redemption Date. A
         similar notice will be mailed by PREIT, postage prepaid, not less than
         30 nor more than 60 days prior to the Redemption Date, addressed to the
         respective holders of record of the Senior Preferred Shares to be
         redeemed at their respective addresses as they appear on the share
         transfer records of PREIT. No failure to give such notice or any defect
         therein or in the mailing thereof will affect the validity of the
         proceeding for the redemption of any Senior Preferred Shares except as
         to the holder to whom notice was defective or not given. Each notice
         will state: (i) the Redemption Date; (ii) the redemption price; (iii)
         the aggregate number of Senior Preferred Shares to be redeemed and, if
         less than all Senior Preferred Shares held by the shareholder are to be
         redeemed, the number of Senior Preferred Shares to be redeemed; (iv)
         the place or places where the certificates for such Senior Preferred
         Shares are to be surrendered for payment of the redemption price; and
         (v) that dividends on the Senior Preferred Shares to be redeemed will
         cease to accrue on such Redemption Date. If fewer than all the Senior
         Preferred Shares held by any holder are to be redeemed, the notice
         mailed to such holder will also specify the number of Senior Preferred
         Shares to be redeemed from such holder. If notice of redemption of any
         Senior Preferred Shares has been properly given and if funds necessary
         for such redemption have been irrevocably set aside by PREIT in trust
         for the benefit of the holders of any of the Senior Preferred Shares so
         called for redemption, then from and after the Redemption Date
         dividends will cease to accrue on such Senior Preferred Shares, such
         Senior Preferred Shares will no longer be deemed to be outstanding and
         all rights of the holders of such Senior Preferred Shares will
         terminate except for the right to receive the applicable redemption
         price and other amounts payable in respect of such Senior Preferred
         Shares.



                                                                     Exhibit 4.1

                  (e) The holders of the Senior Preferred Shares at the close of
         business on a Preferred Dividend Record Date will be entitled to
         receive the dividend payable with respect to such Senior Preferred
         Shares on the corresponding Preferred Dividend Payment Date
         notwithstanding the redemption thereof between such Preferred Dividend
         Record Date and the corresponding Preferred Dividend Payment Date or
         PREIT's default in the payment of the dividend due. Except as provided
         above, PREIT will make no payment or allowance for unpaid dividends,
         whether or not in arrears, on Senior Preferred Shares called for
         redemption.

                  (f) All Senior Preferred Shares redeemed shall be retired and
         shall be restored to the status of authorized and unissued preferred
         shares, without designation as to series, and subject to the applicable
         limitations set forth herein may thereafter be reissued as any series
         of preferred shares.

                  (g) The Senior Preferred Shares have no stated maturity and
         will not be subject to any sinking fund.

                  Section 5 Voting Rights.

                  (a) Holders of the Senior Preferred Shares will not have any
         voting rights, except as set forth below or as otherwise from time to
         time required by law. Subject to the provisions in the Trust Agreement
         regarding Excess Shares (as defined in the Trust Agreement), in any
         matter in which the Senior Preferred Shares may vote, including any
         action by written consent, each Senior Preferred Share will be entitled
         to one vote. The holders of each Senior Preferred Share may separately
         designate a proxy for the vote to which that Senior Preferred Share is
         entitled.

                  (b) Whenever dividends on any Senior Preferred Shares have
         been in arrears for six or more Dividend Periods (regardless of whether
         such periods are consecutive), the holders of such Senior Preferred
         Shares (voting separately as a class with all other series of preferred
         shares upon which rights to vote on such matter with Senior Preferred
         Shares have been conferred and are then exercisable) will be entitled
         to vote for the election of two additional trustees of PREIT at a
         special meeting called by the holders of record of at least 10% of the
         Senior Preferred Shares and such other preferred shares, if any (unless
         such request is received less than 45 days before the date fixed for
         the next annual or special meeting of the shareholders), or at the next
         annual meeting of shareholders, and at each subsequent annual meeting
         until all dividends accumulated on such Senior Preferred Shares for the
         past Dividend Periods and the then current Dividend Period have been
         fully paid or declared and a sum sufficient for the payment thereof set
         aside for payment. In such event, the entire Board of Trustees will be
         increased by two trustees. Each of such two trustees will be elected to
         serve until the earlier of (i) the election and qualification of such
         trustee's successor or (ii) payment of the dividend arrearage for the
         Senior Preferred Shares.



                                                                     Exhibit 4.1

                  (c) If any trustee so elected by the holders of the Senior
         Preferred Shares shall cease to serve as a trustee before such
         trustee's term shall expire, the holders of the Senior Preferred Shares
         (and any other series of preferred shares, if any, entitled to vote on
         such matter, as described above) then outstanding may, at a special
         meeting of the holders called as provided above, elect a successor to
         hold office for the unexpired term of the trustee whose place shall be
         vacant.

                  (d) So long as any Senior Preferred Shares remain outstanding,
         PREIT will not (i) without the affirmative vote or consent of the
         holders of all the Senior Preferred Shares outstanding at the time,
         given in person or by proxy, either in writing or at a meeting (such
         series voting separately as a class), authorize, create or issue, or
         increase the authorized or issued amount of, any class or series of
         capital shares ranking senior to the Senior Preferred Shares with
         respect to payment of dividends or the distribution of assets upon
         liquidation, dissolution or winding up, or create, authorize or issue
         any obligation or security convertible into or evidencing the right to
         purchase any such shares; or (ii) without the affirmative vote or
         consent of the holders of at least two-thirds of the Senior Preferred
         Shares outstanding at the time, given in person or by proxy, either in
         writing or at a meeting (such series voting separately as a class),
         amend, alter or repeal the provisions of the Trust Agreement, whether
         by merger, consolidation or otherwise, so as to materially and
         adversely affect any right, preference, privilege or voting power of
         the Senior Preferred Shares or the holders thereof; provided, however,
         that any increase in the amount of the authorized preferred shares, or
         the creation or issuance of any other series of preferred shares, or
         any increase in the amount of authorized shares of preferred shares or
         any other series of preferred shares, in each case ranking on a parity
         with or junior to the Senior Preferred Shares with respect to payment
         of dividends or the distribution of assets upon liquidation,
         dissolution or winding up of PREIT, will not be deemed to materially
         and adversely affect such rights, preferences, privileges or voting
         powers.

                  (e) The foregoing voting provisions will not apply if, at or
         prior to the time when the act with respect to which such vote would
         otherwise be required is effected, all outstanding Senior Preferred
         Shares have been redeemed or called for redemption upon proper notice
         and sufficient funds have been deposited in trust to effect such
         redemption.

                  Section 6 Ranking.

                  The Senior Preferred Shares will, with respect to dividend
         rights and rights upon liquidation, dissolution or winding up of PREIT,
         rank senior to all existing or future classes or series of equity
         securities of PREIT, except that PREIT may issue additional preferred
         shares which are pari passu with the Senior Preferred Shares so long as
         the aggregate liquidation preference of all of the Senior Preferred
         Shares, together with any such additional preferred shares outstanding,
         does not exceed $123,750,000.


                                                                     Exhibit 4.1

                  Section 7 Restrictions on Transfer.

                  The Senior Preferred Shares shall be subject to the
         limitations on ownership and transfer set forth the Trust Agreement,
         including, without limitation, Paragraph 9 thereof.

                  Section 8 Status of Senior Preferred Shares and Holders
Thereof.

                  In accordance with Section 8 of the Trust Agreement, the
         Senior Preferred Shares shall be included within the term "Shares" and
         the holders of Senior Preferred Shares shall be included within the
         term "Shareholders" for purposes of all provisions of the Trust
         Agreement, other than Paragraph 2.C., the third sentence of Paragraph
         6, Paragraph 10, the second sentence of Paragraph 11.A., the second
         paragraph of Paragraph 11.C., and Paragraph 11.F. thereof.

                  IN WITNESS WHEREOF, Pennsylvania Real Estate Investment Trust
has caused this Certificate of Designation to be executed and delivered on its
behalf by its Chairman and Chief Executive Officer and attested to by its
Secretary on this 14th day of November, 2003.
