indirectly sell, exchange, or otherwise dispose of any Protected Property except
as otherwise expressly permitted pursuant to this Agreement.

qualifies as a like-kind exchange under Section 1031 of the Code, or an
involuntary conversion under Section 1033 of the Code, or other transaction
(including, but not limited to, a contribution of property to any entity that
qualifies for the nonrecognition of gain under Section 721 or Section 351 of the
Code, or a merger or consolidation of PREIT Partnership with or into another
entity that qualifies for taxation as a "partnership" for federal income tax
purposes (a "Successor Partnership")) that does not result in the recognition of
any Original Built-In Gain that would be allocable to a Contributor with respect
to Protected Units; provided, however, that: (i) in the event of a disposition
under Section 1031 or Section 1033 of the Code, any property that is acquired in
exchange for or as a replacement for a Protected Property shall thereafter be
considered a Protected Property for purposes of this Section 2; (ii) if the
Protected Property is transferred to another entity in a transaction in which
gain or loss is not recognized, the interest of PREIT Partnership in such entity
shall thereafter be considered a Protected Property for purposes of this Section
2, and if the acquiring entity's disposition of the Protected Property would
cause a Contributor to recognize any Original Built-In Gain as a result thereof,
the transferred Protected Property still shall be considered a Protected
Property for purposes of this Section 2; and (iii) in the event of a merger or
consolidation involving PREIT Partnership and a Successor Partnership, the
Successor Partnership shall have agreed in writing for the benefit of the
Contributors that all of the restrictions of this Section 2 shall apply with
respect to the Protected Properties, or such restrictions shall otherwise so
apply by operation of law. In addition, none of the transactions that make up
any of the Merger Transactions (including, without limitation, any transactions
involving any of the Liquidating Properties or any interest in any entity that
owns an interest in any of the Liquidating Properties) shall be considered to be
in violation of Section 2(a) of this Agreement.

         (c) Damages. In the event that PREIT Partnership breaches its
obligation set forth in Section 2(a) with respect to a Contributor, except as
set forth in Section 2(d) below, the Contributor's sole right shall be to
receive from PREIT Partnership as damages an amount equal to the following:

                                      -10-


                  (i) If the breach occurs during the First Protection Period,
                  the sum of (A) the Tax Cost attributable to such breach and
                  (B) the Gross-Up Amount.

                  (ii) If the breach occurs during the Second Protection Period,
                  the Interest Expense.

                  (iii) If the breach occurs as a result of an "installment
                  sale" (within the meaning of Section 453(b)(1) of the Code),
                  PREIT Partnership may elect, in its sole and absolute
                  discretion, to pay to each Contributor on an annual basis
                  through the end of the Second Protection Period, in lieu of
                  payment under subclause (i) or (ii) of this Section 2(c), the
                  sum of (A) the amount of the payment that would be required to
                  be made to such Contributor under subclause (i) or (ii), as
                  applicable, with regard to the Original Built-In Gain required
                  to be recognized for the year at issue as a result of such
                  breach, after taking into account the application of the
                  "installment sale" rules, plus (B) the lesser of (1.) the
                  product of (a) the amount of the Original Built-In Gain that
                  is deferred to a subsequent year under the "installment sale"
                  rules multiplied by (b) the interest rate specified in Section
                  453A(c)(2)(B) of the Code, and (2.) the actual amount of
                  interest payable by such Contributor with respect to the year
                  at issue under Section 453A(c) of the Code (which amount shall
                  be determined for each year on the basis of a certificate
                  addressed to PREIT Partnership from the entity that prepared
                  or reviewed the federal income tax return of the Contributor
                  for the relevant taxable year, which certificate shall state
                  and warrant either (x) the actual amount of interest reported
                  on the Contributor's federal income tax return as due to the
                  Internal Revenue Service from such Contributor with respect to
                  such year pursuant to Section 453A of the Code, or (y) that
                  the amount described in subclause (1.) above with respect to
                  the Contributor was less than the actual amount of interest
                  reported on the Contributor's federal income tax return as due
                  to the Internal Revenue Service from such Contributor with
                  respect to such year pursuant to Section 453A of the Code).

                                      -11-


         (d) Assumptions Regarding Determination of Tax Cost and Related
Amounts.

                  (i) In determining the Tax Cost, the Gross-Up Amount and/or
         the Interest Expense for purposes of Section 2(c) and related
         provisions of this Section 2, only Original Built-In Gain required to
         be recognized by the respective Contributor by reason of the breach of
         the covenants set forth in Section 2(a) and allocated to such
         Contributor from PREIT Partnership by reason of Section 704(c) of the
         Code shall be taken into account. Prior to the closing of the Crown
         Merger, Crown Partnership distributed to Crown in liquidation of
         Crown's interest in Crown Partnership the Crown Proportionate Interest
         in substantially all of the assets of Crown Partnership (including,
         directly or indirectly, each of the Protected Properties), subject to a
         percentage of the liabilities of Crown Partnership equal to the Crown
         Proportionate Interest. It is the understanding and intention of the
         parties that, as a result of such distribution in liquidation of
         Crown's interest by Crown Partnership to Crown, the Original Built-In
         Gain attributable to the Protected Properties that would be allocable
         to the Contributors in the future was reduced by a percentage equal to
         the Crown Proportionate Interest.

                  (ii) Each of the parties hereto agrees (A) that, for purposes
         of computing the Tax Cost, the Gross-Up Amount and/or the Interest
         Expense for purposes of Section 2(c) and related provisions of this
         Section 2, unless there is a Final Determination to the contrary, such
         computations shall be made assuming that the Original Built-In Gain
         attributable to the Protected Properties that would be allocable to the
         Contributors in the future was reduced by a percentage equal to the
         Crown Proportionate Interest prior to the contribution of the Protected
         Properties to PREIT Partnership as part of the Merger Transactions (the
         "Assumed Built-In Gain Calculation"), and (B) to prepare its tax
         returns and/or information returns relating to any transaction that
         results in the recognition of Original Built-In Gain by PREIT
         Partnership and/or any of the Contributors in a manner consistent with
         the Assumed Built-In Gain Calculation and not to take any position or
         make any assertion inconsistent therewith in any proceedings with the
         Internal Revenue Service or any other taxing authority. Any challenge
         by the Internal Revenue Service or any other taxing authority relating
         to the Assumed Built-In Gain Calculation shall be governed by Section 7
         below.

                  (iii) In the event of a Final Determination that the
         percentage of the Original Built-In Gain of Crown Partnership allocable
         to the Contributors exceeds the amount contemplated under the Assumed
         Built-In Gain Calculation and such increased amount is not attributable
         to either the fact that Crown Partnership or any partnership in which
         Crown Partnership owned an interest had in effect with respect to the

                                      -12-


         taxable year in which the Merger Transactions closed a "Section 754
         election," or a breach by any of the Contributors of their obligations
         set forth in Section 2(d)(ii)(B) and/or Section 6(a) below, the amount
         of damages under Section 2(c) for a breach of Section 2(a) shall equal:

                  (A) if the breach of Section 2(a) occurs during the First
                  Protection Period, the sum of (1.) the Tax Cost and (2.) the
                  Gross-Up Amount (both calculated without giving effect to the
                  limitations in Sections 2(d)(i) and 2(d)(ii) and based upon
                  the actual amount of such Original Built-In Gain required to
                  be recognized as a result of such Final Determination); and

                  (B) if the breach of Section 2(a) occurs during the Second
                  Protection Period:

                           (1.) with regard to the first $85.0 million of
                           Original Built-In Gain allocable to the Contributors,
                           in the aggregate, as a result of one or more breaches
                           of Section 2(a) during the Second Protection Period,
                           the Interest Expense attributable to the actual
                           amount of such Original Built-In Gain required to be
                           recognized during the Second Protection Period;

                           (2.) with regard to 50% of the Original Built-In Gain
                           in excess of $85.0 million that is allocable to the
                           Contributors, in the aggregate, as a result of one or
                           more breaches of Section 2(a) during the Second Tax
                           Protection Period, the Interest Expense attributable
                           to the actual amount of such Original Built-In Gain;
                           and

                           (3.) with regard to the remaining 50% of the Original
                           Built-In Gain in excess of $85.0 million that is
                           allocable to the Contributors, in the aggregate, as a
                           result of one or more breaches of Section 2(a) during
                           the Second Tax Protection Period, the sum of (a) the
                           Tax Cost and (b) the Gross-Up Amount attributable to
                           the actual amount of such Original Built-In Gain.

         (e) Sole and Exclusive Remedy. Notwithstanding any provision of this
Agreement, the sole and exclusive rights and remedies of any Contributor for a
breach or violation of the covenants set forth in Section 2(a) shall be a claim
for damages against PREIT Partnership, computed as set forth in Sections 2(c)
and (d), and no Contributor shall be entitled to pursue a claim for specific
performance of the covenants set forth in Section 2(a) or bring a claim against

                                      -13-


any person that acquires a Protected Property from PREIT Partnership in
violation of Section 2(a) (other than a Successor Partnership that has agreed in
writing to be bound by the terms of this Agreement or that has otherwise
succeeded to all of the assets and all of the liabilities of PREIT Partnership,
but then only for damages computed as set forth in Sections 2(c) and 2(d)).

         (f) Determination Procedures; Payment Schedule.

                  (i) If PREIT Partnership has breached or violated the covenant
                  set forth in Section 2(a) (or a Contributor asserts that PREIT
                  Partnership has breached or violated the covenants set forth
                  in Section 2(a)), PREIT Partnership and the Contributor agree
                  to negotiate in good faith to resolve any disagreements
                  regarding any such breach or violation and the amount of
                  damages, if any, payable to such Contributor, as computed
                  under Sections 2(c) and 2(d). If any such disagreement cannot
                  be resolved by PREIT Partnership and such Contributor within
                  sixty (60) days after such breach, PREIT Partnership and the
                  Contributor shall jointly retain an arbitrator (the
                  "Arbitrator") to resolve as expeditiously as possible all
                  points of any such disagreement (including, without
                  limitation, whether a breach of the covenant set forth in
                  Section 2(a) has occurred and, if so, the amount of damages to
                  which the Contributor is entitled as a result thereof,
                  determined as set forth in Sections 2(c) and (d)). If the
                  disagreement is based solely on the amount of damages (and not
                  as to whether a breach has occurred), then PREIT Partnership
                  and the Contributor shall jointly retain a nationally
                  recognized independent public accounting firm (an "Accounting
                  Firm") to act as an arbitrator for the purpose of resolving as
                  expeditiously as possible the amount of damages to which the
                  Contributor is entitled as a result of the breach. (The amount
                  of damages to be determined by the Arbitrator or Accounting
                  Firm, as applicable, shall include any interest required to be
                  paid to any taxing authority (other than interest that, to the
                  extent Section 2(c)(ii) applies, is compensated for by the
                  payment to the Contributor of Interest Expense, and to the
                  extent Section 2(c)(iii) applies, is compensated for by the
                  payments provided for therein) and any penalties or additions
                  to tax required to be paid to any taxing authority caused by
                  PREIT Partnership's delay in payment.) All determinations made
                  by the Arbitrator or the Accounting Firm, as applicable, with
                  respect to the resolution of any breach or violation of the
                  covenants set forth in Section 2(a) and the amount of damages
                  payable to the Contributor under Sections 2(c) and 2(d) shall
                  be final, conclusive and binding on PREIT Partnership and the
                  Contributor. The fees and expenses of any Arbitrator or
                  Accounting Firm shall be shared equally by PREIT Partnership
                  and the Contributor.

                                      -14-

                  (ii) PREIT Partnership shall pay any damages payable to a
                  Contributor under Section 2(c) or Section 2(d) on the
                  Contributor's Assumed Tax Payment Date, or, if later, not
                  later than ten business days following a determination of
                  damages in accordance with this Section 2(f); provided,
                  however, that, subject to the determination procedures
                  described in this Section 2(f), (i) the Interest Expense shall
                  be paid on the closest business day falling on or before the
                  last day of each calendar quarter during the term such
                  Interest Expense is (or would be, in the case of a
                  hypothetical loan) payable, except that the last payment shall
                  be made on the last day of the Second Protection Period; and
                  (ii) each annual payment, if any, pursuant to Section
                  2(c)(iii) shall be made not later than five business days
                  prior to the due date (determined without regard to any
                  extensions thereof) for the filing of such Contributor's tax
                  return for the taxable year to which such payment relates.

                  (iii) If PREIT Partnership makes a payment for damages under
                  this Section 2 and, at any time thereafter, there is a Final
                  Determination that the Contributor is required to recognize a
                  greater amount of income or gain than the income or gain
                  assumed when calculating such damages, the difference between
                  the damages calculated using the redetermined income or gain
                  and the damages previously paid shall be paid by PREIT
                  Partnership within ten (10) business days of the Final
                  Determination.

         3. Election by Contributors to Enter into Guarantees of Debt of PREIT
Partnership.

                  (a) Requirement to Provide Guarantee Opportunity. During the
         First Protection Period and, if a Guarantee Partner shall so elect in a
         written notice to PREIT Partnership received at least 15 days prior to
         the termination of the First Protection Period on _________, 2008,
         during the remaining portion of the Guarantee Protection Period, PREIT
         Partnership shall make available to each Guarantee Partner the
         opportunity (a "Guarantee Opportunity") to make a "bottom guarantee" of
         Qualifying Debt of PREIT Partnership or a Subsidiary in the form of the
         Guaranty Agreement and in an amount equal with respect to each
         Guarantee Partner to the amount set forth on Schedule 2 to this
         Agreement, determined taking into account all existing guarantees of
         such Guarantee Partner that are then in effect (treating as "bottom
         guarantees" for this purpose the guarantees that are in effect with
         respect to the indebtedness that is guaranteed as of _________, 2003,
         by the Guarantee Partners pursuant to the Guaranty Agreement, as set
         forth on Schedule 2 to this Agreement). During the Guarantee Protection
         Period, if part or all of a Guaranteed Debt is repaid and, immediately
         after such repayment, (i) the amount remaining outstanding with respect
         to such Guaranteed Debt would be less than the Guaranteed Amount with
         respect to such Guaranteed Debt or (ii) the Guaranteed Debt no longer

                                      -15-


         would be treated as Qualifying Debt, PREIT Partnership shall provide to
         each Guarantee Partner that had a Guaranteed Amount with respect to
         such Guaranteed Debt a new Guarantee Opportunity in an amount equal to
         such Partner's Guaranteed Amount with respect to the Guaranteed Debt
         being repaid or no longer qualifying as Qualifying Debt, provided that
         if the Guaranteed Debt is not being repaid in full, the new Guaranty
         Opportunity can be an offer to allow a guarantee of a portion of that
         remaining debt so long as the remaining portion of such debt, after
         taking into account the Guaranty Opportunities being offered with
         respect thereto, would be Qualifying Debt.

                  In the event that PREIT Partnership is required to offer a
         Guarantee Opportunity pursuant to this Section 3(a), PREIT Partnership
         will provide the Guarantee Partners notice of the type, amount and
         other relevant attributes of the Qualifying Debt with respect to which
         the Guarantee Opportunity is offered at least twenty (20) business days
         prior to (x) the earlier of the closing of the incurrence of such debt
         and the scheduled repayment of the existing Guaranteed Debt and (y) any
         subsequent date on which PREIT Partnership makes available additional
         Guarantee Opportunities by reason of the repayment of any indebtedness
         then subject to a Guarantee by the Guarantee Partners. In the event
         that PREIT Partnership repurchases outstanding Guaranteed Debt, whether
         or not such debt is retired, the repurchase thereof shall be treated as
         a repayment of the Guaranteed Debt for purposes of this Section 3.

                  (b) Agreement to Use Commercially Reasonable Efforts to
         Provide Additional Guarantee Opportunities. After the expiration of the
         Guarantee Protection Period, PREIT Partnership agrees to use
         commercially reasonable efforts to make available to each Guarantee
         Partner a Guarantee Opportunity under terms similar to those described
         in Section 3(a) above, provided, however, that the Guaranteed Amount of
         each Guarantee Partner shall not exceed the lesser of the amount of
         such Guarantee Partner's negative tax capital account with respect to
         Crown Partnership on the last day of the Guarantee Protection Period or
         such Guarantee Partner's negative tax capital account with respect to
         Crown Partnership on the date hereof. PREIT Partnership's only
         obligation with respect to this Section 3(b) shall be to use
         commercially reasonable efforts. In the event PREIT Partnership fails
         to use commercially reasonable efforts to provide additional guarantee
         opportunities to each Guarantee Partner under this Section 3(b), the
         exclusive remedy of such Guarantee Partners shall be an action for
         specific performance, with no entitlement to monetary damages.

                                      -16-


                  (c) No Representations or Warranties. PREIT Partnership makes
         no representation or warranty to any Guarantee Partner that any
         guarantee currently in effect or any guarantee entered into pursuant to
         Section 3(a) or Section 3(b) shall be respected for federal income tax
         purposes for purposes of causing the Guarantee Partner to be considered
         to bear the "economic risk of loss" with respect to the indebtedness
         thereby guaranteed by such Guarantee Partner for purposes of either
         Section 752 or Section 465 of the Code.

                  (d) Damages. In the event that PREIT Partnership breaches its
         obligation set forth in Section 3(a) with respect to a Guarantee
         Partner during the Guarantee Protection Period, the Guarantee Partner's
         sole right shall be to receive from PREIT Partnership as damages an
         amount equal to the sum of (A) the Tax Cost as a result of such breach
         and (B) the Gross-Up Amount.

                  In no event shall the amount taken into account for purposes
         of computing the damages payable under this Section 3(d) exceed the
         amount of gain that would have been recognized by the Guarantee Partner
         if, at the closing of the Merger Transactions, such Guarantee Partner
         had recognized an amount of gain equal to the "negative tax capital
         account" that it had with respect to its interest in the Crown
         Partnership at the time of the Merger Transactions, determined taking
         into consideration any adjustments occurring as a direct result of the
         Merger Transactions, provided that such adjustments do not result in a
         "negative tax capital account" that exceeds the Guaranteed Amount with
         respect to such Guarantee Partner. PREIT Partnership shall be
         considered to have satisfied its obligations under Section 3(a), and
         therefore shall have no liability under this Section 3(d), if it makes
         an offer to a Guarantee Partner of an opportunity to guarantee
         Qualifying Debt within the time periods specified in Section 3(a) and
         PREIT Partnership shall have no liability if a Guarantee Partner fails
         to join in such guarantee of Qualifying Debt.

                  This Section 3(d) shall have no application in the event of a
         breach by PREIT Partnership of its obligations under Section 3(b), the
         exclusive remedy of a Contributor for any such breach being an action
         for specific performance of the obligations of PREIT Partnership
         thereunder.

                  (e) Sole and Exclusive Remedy; Payment Schedule.

                           (i) Notwithstanding any provision of this Agreement,
                           the sole and exclusive rights and remedies of any
                           Guarantee Partner for a breach or violation of the
                           covenants set forth in Section 3(a) shall be a claim
                           for damages against PREIT Partnership, computed as
                           set forth in Section 3(d), and no Guarantee Partner
                           shall be entitled to pursue a claim for specific
                           performance of the covenants set forth in Section

                                      -17-


                           3(a). If PREIT Partnership has breached or violated
                           the covenant set forth in Section 3(a) (or a
                           Guarantee Partner asserts that PREIT Partnership has
                           breached or violated the covenant set forth in
                           Section 3(a)), procedures similar to those described
                           in Section 2(f)(i) shall apply (substituting for this
                           purpose, to the extent relevant, "Section 3" for
                           "Section 2" wherever "Section 2" appears).

                           (ii) Payment of damages required under Section 3(d)
                           shall be made under the same principles as those set
                           forth in Sections 2(f)(ii) and (iii) (substituting
                           for this purpose, to the extent relevant, "Section 3"
                           for "Section 2" wherever "Section 2" appears).

                  (f) Allocation Covenant. PREIT Partnership acknowledges that
         the purpose of providing Guarantee Opportunities and specifically
         allowing the Contributors to guarantee Qualifying Debt is to provide
         for an allocation under Section 752 of the Code of the indebtedness of
         PREIT Partnership and its Subsidiaries to the Contributors in an amount
         equal to the Guaranteed Amount. Subject to Section 6(b) hereof and the
         following, PREIT Partnership shall file its tax returns in a manner
         consistent with such allocation. PREIT Partnership shall not be
         required to make allocations of Guaranteed Debt to the Contributors as
         set forth above if and to the extent that PREIT Partnership determines
         in good faith that there may not be "substantial authority" (within the
         meaning of Section 6662(d)(2)(B)(i)) of the Code for such allocations;
         provided that PREIT Partnership shall provide to the Contributors
         notice of such determination and if, within forty five (45) days after
         the receipt of such notice, PREIT Partnership is provided an opinion of
         Reed Smith, Sullivan & Cromwell, or Ernst & Young (or another
         comparable law firm or Accounting Firm) to the effect that there is
         "substantial authority" (within the meaning of Section 6662(d)(2)(B)(i)
         of the Code) for such allocations, PREIT Partnership shall continue to
         make allocations of Guaranteed Debt to the Contributors as set forth in
         the first and second sentences of this Section 3(f). Notwithstanding
         the foregoing, if there shall have been a judicial determination in a
         proceeding to which PREIT Partnership is a party and as to which the
         Contributors have been allowed to participate (as and to the extent
         contemplated in Section 7) to the effect that such allocations are not
         correct, the first and second sentences of this Section 3(f) shall not
         apply unless (i) the matter is being appealed to an applicable court of
         appeals, (ii) the requirements of Sections 7(b)(i) (y) and (z) shall
         have been satisfied in connection therewith, and (iii) the opinion
         described above from a law firm or an Accounting Firm engaged by a
         Contributor shall have been provided, except that such opinion shall be
         to the effect that it is "more likely than not" that such allocations
         will be respected. In no event shall this Section 3(f) be construed as
         to relieve PREIT Partnership for liability arising from a failure by
         PREIT Partnership to comply with one or more of the provisions of
         Section 3(a) of this Agreement.

                                      -18-


                  (g) Cooperation in the Event of a Change. If a change in PREIT
         Partnership's allocations of Guaranteed Debt to the Contributors is
         required by reason of circumstances described in Section 3(f), PREIT
         Partnership and its professional tax advisors shall cooperate in good
         faith with the Contributors and their professional tax advisors to
         develop alternative allocation arrangements and/or other mechanisms
         that protect the federal income tax positions of the Contributors with
         respect to their "negative tax capital accounts" in the manner
         contemplated by the allocations of Guaranteed Debt to the Contributors
         as set forth in this Agreement.

         4. No Obligation of PREIT Partnership to Maintain Debt; No Other
Limitations.

                  (i) Notwithstanding any obligations of PREIT Partnership
                  referred to in this Agreement or otherwise, PREIT Partnership
                  shall not be obligated to maintain any level of indebtedness
                  in excess of the amounts specifically required to meet the
                  obligations set forth in Section 3 above.

                  (ii) Except as set forth in Section 2 and in Section 3 above,
                  neither PREIT Partnership nor PREIT shall be under any
                  restriction or limitation as to the actions it can take with
                  respect to the Protected Properties and the indebtedness of
                  PREIT Partnership and its Subsidiaries, whether by reason of
                  fiduciary duty or otherwise, regardless of the tax
                  consequences that such action (or any failure to act) might
                  have for one or more Contributors.

         5. No Limitations After Expiration of Term of the Agreement. After the
expiration of the applicable protection period, except to the extent of PREIT
Partnership's obligation under Section 3(b),

                  (a) the restrictions set forth in Sections 2 and 3 with
         respect to the Protected Properties and the Guaranty Agreements shall
         be of no force and effect;

                  (b) neither PREIT Partnership nor PREIT shall be under any
         restriction or limitation as to the actions it can take with respect to
         the Protected Properties and the indebtedness of PREIT Partnership and
         its Subsidiaries, whether by reason of fiduciary duty or otherwise,
         regardless of the tax consequences that such action (or any failure to
         act) might have for one or more Contributors; and

                                      -19-


                  (c) PREIT Partnership and PREIT shall have no duty to consider
         the tax consequences to the Contributors of any action (or failure to
         act) with respect to the Protected Properties or the indebtedness of
         PREIT Partnership and its Subsidiaries.

         6. Income Tax Reporting Obligations of the Parties.

                  (a) Reporting Obligations. Each party hereto agrees that its
         tax returns and/or information returns will be prepared in a manner
         that reflect the intent of the parties set forth below:

                  (i) Whether, and the extent to which, gain recognized as a
                  result of a breach of Section 2(a) and allocated to a
                  Contributor is attributable to the Original Built-In Gain of
                  the Protected Property subject to the disposition shall be
                  determined under normal tax accounting rules, with the result
                  that the parties hereto will treat any such recognized gain as
                  attributable solely to the Original Built-In Gain of the
                  Protected Property until all of such Original Built-In Gain
                  has been recognized.

                  (ii) The amount of the Original Built-In Gain of Crown
                  Partnership allocable to the Contributors does not exceed the
                  amount determined under the Assumed Built-In Gain Calculation.

                  (b) No Representations, Warranties, or Liabilities. PREIT and
         PREIT Partnership make no representation or warranty to the
         Contributors that any of the reporting positions described in Sections
         3(f) and 6(a) and intended to be taken thereunder will be respected by
         the Internal Revenue Service, or that if any such position is
         challenged by the Internal Revenue Service, such challenge will not be
         successful. Except to the extent of PREIT Partnership's express
         obligations under Section 2 of this Agreement, neither PREIT nor PREIT
         Partnership shall have any liability to any Contributor under any
         circumstances in the event of a challenge by the Internal Revenue
         Service to any of the reporting positions described in Sections 3(f)
         and 6(a) so long as PREIT and PREIT Partnership have complied in good
         faith with their obligation to report such matters in the manner
         intended in Sections 3(f) and 6(a). In the event that, as the result of
         a change in statute or Treasury Regulations or a judicial decision or
         published revenue ruling or similar administrative pronouncement
         occurring subsequent to the date hereof, PREIT, as general partner of
         PREIT Partnership, determines in good faith that there is no longer a
         substantial basis for taking a reporting position contemplated by
         Section 3(f) or Section 6(a), no party hereto shall be required
         thereafter to take such reporting position; provided, however, that
         PREIT Partnership shall provide notice of such determination to each

                                      -20-


         Contributor and if any Contributor shall, within 30 days of receipt of
         such notice, provide to PREIT Partnership an opinion of Reed Smith,
         Sullivan & Cromwell LLP or other tax counsel, which other counsel shall
         be reasonably acceptable to PREIT Partnership, to the effect that none
         of PREIT, PREIT Partnership, any of their affiliates or any person
         signing the applicable tax returns will be subject to any monetary or
         disciplinary penalty if PREIT and PREIT Partnership continue to take
         such reporting position, then PREIT and PREIT Partnership will continue
         to take such reporting position.

         7. Contests and Audits.

                  (a) Notification of Audits or Disputes. Upon receipt by a
         party of any pending or threatened tax audit or assessment that may
         affect the determination of (i) the amount of Original Built-In Gain
         allocable to a Contributor by PREIT Partnership for a transaction or
         event that occurred prior to the expiration of the Second Tax
         Protection Period or (ii) the amount of liabilities allocated to a
         Contributor by PREIT Partnership under Section 752 of the Code for a
         period ending prior to the expiration of the Guarantee Protection
         Period pursuant to Section 3(b), such party shall notify the other
         party in writing within fourteen (14) days of the receipt of such
         notice.

                  (b) Control and Settlement.

                           (i) Except as otherwise provided in this paragraph,
                           PREIT Partnership shall have (A) the exclusive right
                           (but, except as described in clause (y), not the
                           obligation) to control, and to represent the
                           interests of all affected taxpayers in, any tax audit
                           or administrative, judicial or other proceeding
                           described above in Section 7(a) and to employ counsel
                           of its choice, at PREIT Partnership's expense, and
                           (B) in the case of any proceeding involving the
                           matter described in clause (i) of Section 7(a), the
                           obligation to defend the position contemplated by
                           this Agreement, at the expense of PREIT Partnership;
                           provided, however, that PREIT Partnership shall not
                           enter into any settlement that affects, directly or
                           indirectly, the determination of the amount of
                           Original Built-In Gain allocable to a Contributor by
                           PREIT Partnership required to be recognized during
                           either the First Protection Period or the Second
                           Protection Period or the determination of the amount
                           of liabilities allocated to a Contributor under
                           Section 752 of the Code without the prior written
                           consent of such Contributor, which shall not be
                           unreasonably withheld. Each such Contributor shall
                           provide a written response to any written
                           notification by PREIT Partnership of a proposed
                           settlement within at least thirty (30) days (the

                                      -21-


                           "Response Period") of the receipt by the Contributor
                           of such notification. As a condition to withholding
                           its consent to a settlement pursuant to the preceding
                           sentence, a Contributor must: (x) have a reasonable
                           basis to believe that such settlement would have an
                           adverse impact on one or more of the Contributors
                           with respect to a matter covered by this Agreement,
                           (y) believe, based upon the advice of Reed Smith,
                           Sullivan & Cromwell LLP, or Ernst & Young LLP (or
                           another comparable law firm or Accounting Firm), that
                           it is "more likely than not" that the position
                           asserted by the Contributor would prevail if it were
                           to be asserted in a judicial proceeding (and upon the
                           written request of PREIT Partnership, such
                           Contributor shall provide to PREIT Partnership a
                           letter from such law firm or Accounting Firm
                           confirming such advice), and (z) except as
                           contemplated by clause (ii)(B) below with respect to
                           matters described in Section 7(a)(i), offer to assume
                           the subsequent costs of defending and asserting the
                           position asserted by the Contributor. If PREIT
                           Partnership has not received a response from such
                           Contributor within the first fourteen (14) days of
                           the Response Period, PREIT Partnership shall provide,
                           not less than ten (10) days prior to the expiration
                           of the Response Period, another written notification
                           (the "Final Notice") to the Contributor of the
                           proposed settlement. If PREIT Partnership has timely
                           provided the Final Notice and such Contributor fails
                           to so respond within the Response Period, such
                           Contributor shall be deemed to have consented to the
                           proposed settlement.

                           (ii)

                  (A) Except as provided in clause (B) below, in the event that
         PREIT, as general partner of PREIT Partnership, determines, in good
         faith and based on a reasoned analysis of outside advisors to PREIT
         provided in writing (which written analysis PREIT will share with the
         Contributors, if requested to do so), that PREIT Partnership would be
         unlikely to prevail if it were to contest any tax audit or
         administrative, judicial or other proceeding described above in Section
         7(a), PREIT Partnership may elect not to contest any such proceeding,
         provided, however, that, in this event, any of the Contributors shall
         then be entitled to elect to contest any such proceeding, at such
         Contributor's own expense. PREIT Partnership shall use good faith
         efforts to provide to any Contributor and its designated tax advisor
         the opportunity to participate in any tax audit or administrative,
         judicial or other proceeding described above in Section 7(a), subject
         to the following conditions: (1.) such participation shall be
         exclusively at the expense of the Contributor and at no expense to
         PREIT Partnership, and (2.) PREIT Partnership may place such
         limitations on any such participation as it determines in good faith
         are necessary or appropriate to avoid prejudicing its ability to
         contest any adverse determination or assertion involving the amount, if
         any, of the Original Built-In Gain required to be recognized by any one
         or more of the Contributors during either the First Protection Period
         or the Second Protection Period.

                                      -22-


                  (B) Notwithstanding clause (A) above, PREIT Partnership shall
         undertake, at its expense, to contest a tax audit or administrative,
         judicial or other proceeding described above in Section 7(a)(i) if a
         Contributor provides to PREIT Partnership a letter from Reed Smith,
         Sullivan & Cromwell LLP, or Ernst & Young LLP (or another comparable
         law firm or Accounting Firm) to the effect that it is more likely than
         not that the position asserted by the Contributor would prevail if it
         were to be asserted in a judicial proceeding.

                  (C) The liability of PREIT Partnership with respect to any
         Original Built-In Gain required to be recognized by any Contributor
         shall be determined solely under Sections 2(c) and 2(d) above, and
         PREIT Partnership, in no event, shall have any liability, monetary or
         otherwise, relating to or arising out of the conduct of any proceedings
         pursuant to its authority under this Section 7, except as expressly
         provided for under Sections 2(c) and 2(d) above. The exclusive remedy
         of any Contributor with respect to a claimed breach by PREIT
         Partnership of its obligations under this Section 7 shall be an action
         for specific performance, provided that the foregoing shall not in any
         way limit the right of a Contributor to damages expressly provided for
         in Section 2(c), Section 2(d) and Section 3(d) above.

         8. Section 704(c) Method. Notwithstanding any provision of the PREIT
Partnership Agreement, PREIT Partnership shall use the "traditional method"
under Treasury Regulations Section 1.704-3(b) for purposes of making allocations
under Section 704(c) of the Code with respect to each of the Protected
Properties, with no "curative" or "remedial" allocations under Section 704(c) of
the Code other than, to the extent permitted under Treasury Regulations ss.
1.704-3(c), curative allocations of gain recognized on a disposition of an
interest in any Crown Property to offset the impact of the "ceiling rule" with
respect to such property. The fair market values of the Crown Properties for
purposes of making allocations pursuant to Section 704(c) of the Code with
respect to the Crown Properties shall be the fair market values determined for
purposes of the financial statements of PREIT and PREIT Partnership to be filed
with the Securities and Exchange Commission with respect to the period following
the Merger.

         9. Liability for Certain Real Estate Transfer Taxes. Notwithstanding
any other agreement to the contrary, PREIT Partnership hereby agrees, on the one
hand, and each of CIT and CAIC (collectively, the "Crown Indemnifying Parties")
hereby agrees, jointly and severally, on the other hand, that, in the event any

                                      -23-


realty transfer, recording or other similar taxes are imposed by the
Pennsylvania Department of Revenue or any similar realty transfer, recording or
other similar tax is imposed by the taxing authority of a locality located in
the State of Pennsylvania on CFLP or WCALP (or PREIT Partnership, CIT, CAIC or
any affiliate thereof) as a result of the transfers of partnership interests in
either of CFLP or WCALP as part of the Merger Transactions or pursuant to
Section 4 of the Crown Partnership Contribution Agreement, the aggregate cost
equal to the sum of (a) all such realty transfer taxes imposed plus (b) any
related interest required to be paid to any taxing authority plus (c) any
related penalties or additions to tax required to be paid to any taxing
authority shall be borne in the following proportion: (i) 50% by PREIT
Partnership, and (ii) 50% by CIT and CAIC, jointly and severally. Each party
described in this paragraph 9 agrees to file any returns or other documents
required in connection with the realty transfer taxes described herein and to
pay in a timely manner all amounts due by it to the applicable taxing
authorities. Upon receipt by any party described in this paragraph 9 of any
pending or threatened tax audit or assessment that may result in a payment under
this paragraph 9, such party shall notify the other parties in writing within
fourteen (14) days of the receipt of such notice. The Crown Indemnifying Parties
shall pay to PREIT Partnership in cash or readily available funds any amounts
required to be paid by the Crown Indemnifying Parties not later than ten (10)
days after the receipt of written notice from PREIT Partnership that such amount
is due and payable hereunder.

         10. Waiver and Amendment. Any party hereto may waive its rights under
this Agreement at any time, and no such waiver shall operate to waive any
party's rights under this Agreement with respect to any subsequent event. Any
agreement on the part of any such party to any such waiver shall be valid only
if set forth in an instrument in writing signed by such party. This Agreement
may be amended only by a written instrument signed by the parties hereto.

         11. Invalid Provision. The invalidity or unenforceability of any
particular provision of this Agreement shall not affect the other provisions
hereof, and this Agreement shall be construed in all respects as if such invalid
or unenforceable provisions were omitted.

                               GUARANTY AGREEMENT
                               ------------------



         THIS GUARANTY AGREEMENT ("Guarantee"), dated as of _________, 2003, is
made by those certain undersigned Persons identified on Schedule 1 attached
hereto ("Guarantors"), in favor of [LENDER] ("Guaranteed Party").

         WHEREAS, [BORROWER] ("Maker"), is indebted to the Guaranteed Party in
the sum of [LOAN], as evidenced by a certain Promissory Note dated [DATE] (the
"Note"), which is secured by a Mortgage (the "Mortgage") on certain property of
the Maker (the "Properties" and individually, a "Property").

         WHEREAS, the Guarantors desire to guarantee collection of a portion of
the principal amount of the Note not in excess of [Guaranteed Amount] (the
"Guaranteed Amount").

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, and intending to be legally bound
hereby, Guarantors agree as follows:

                  1. Guarantee

         A. The Guarantors hereby irrevocably and unconditionally guarantee the
collection by the Guaranteed Party of, and hereby agree to pay to the Guaranteed
Party upon demand (following (1) foreclosure of the Mortgage, exercise of the
powers of sale thereunder and/or acceptance by the Guaranteed Party of a deed to
a Property in lieu of foreclosures, and (2) the exhaustion of the exercise of
any and all remedies available to the Guaranteed Party against Maker, including,
without limitation, realizing upon the assets of Maker other than the
Properties), an amount equal to the excess, if any, of the Guaranteed Amount
over the Maker Proceeds (as hereinafter defined). The amounts payable by each
Guarantor in respect of the guarantee obligations hereunder shall be in the same
proportion as the amounts listed next to such Guarantor's name on Schedule 2
attached hereto bears to the Guaranteed Amount provided that, notwithstanding
anything to the contrary contained in this Guarantee, each Guarantor's
obligation shall be limited to the amount(s) set forth on Schedule 2 next to
such Guarantor's name. The Guarantors' obligations as set forth in this
Paragraph 1.A. are hereinafter referred to as the "Guaranteed Obligations."

         B. For the purposes of this Guarantee, the term "Maker Proceeds" shall
mean the aggregate of the Foreclosure Proceeds (as hereinafter defined) plus all
amounts collected from the Maker or realized from the sale of assets of the
Maker other than the Properties.




         C. For the purposes of this Guarantee, the term "Foreclosure Proceeds"
shall have the applicable meaning set forth below with respect to a Property:

                  1. If at least one bona fide third party unrelated to the
         Guaranteed Party (and including, without limitation, any of the
         Guarantors) bids for such Property at a sale thereof, conducted upon
         foreclosure of the related Mortgage or exercise of the power of sale
         thereunder, Foreclosure Proceeds shall mean the highest amount bid for
         such Property by the party that acquires title thereto (directly or
         through a nominee) at or pursuant to such sale. For the purposes of
         determining such highest bid, amounts bid for the Property by the
         Guaranteed Party shall be taken into account notwithstanding the fact
         that such bids may constitute credit bids which offset against the
         amount due to the Guaranteed Party under the Note.

                  2. If there is no such unrelated third-party at such sale of
         the Property so that the only bidder at such sale is the Guaranteed
         Party or its designee, the Foreclosure Proceeds shall be deemed to be
         fair market value (the "Fair Market Value") of the Property as of the
         date of the foreclosure sale, as such Fair Market Value shall be
         mutually agreed upon by the Guaranteed Party and the Guarantor or
         determined pursuant to subparagraph 1.D.

                  3. If the Guaranteed Party receives and accepts a deed to the
         Property in lieu of foreclosure in partial satisfaction of Maker's
         obligations under the Note, the Foreclosure Proceeds shall be deemed to
         be the Fair Market Value of such Property as of the date of delivery of
         the deed-in-lieu of foreclosure, as such Fair Market Value shall be
         mutually agreed upon by the Guaranteed Party and the Guarantor or
         determined pursuant to subparagraph 1. D.

         D. Fair Market Value of a Property shall be the price at which a
willing seller not compelled to sell would sell such Property, and a willing
buyer not compelled to buy would purchase the Property, free and clear of all
mortgages but subject to all leases and reciprocal easement and operating
agreements. If the Guaranteed Party and Guarantor are unable to agree upon the
Fair Market Value of a Property in accordance with subparagraphs 1.C.2. or 3.
above, as applicable, within twenty (20) days after the date of the foreclosure
sale or the delivery of the deed-in-lieu of foreclosure, as applicable, relating
to a Property, either party may have the Fair Market Value of a Property

                                      -3-


determined by appraisal by appointing an appraiser having the qualifications set
forth below to determine the same and by notifying the other party of such
appointment within twenty (20 days after the expiration of such twenty (20) day
period. If the other party shall fail to notify the first party, within twenty
(20) days after its receipt of notice of the appointment by the first party, of
the appointment by the other party of an appraiser having the qualifications set
forth below, the appraiser appointed by the first party shall alone make the
determination of such Fair Market Value. Appraisers appointed by the parties
shall be members of the Appraisal Institute (MAI) and shall have at least ten
years' experience in the valuation of properties similar to the Property being
valued in the greater metropolitan area in which such Property is located. If
each party shall appoint an appraiser having the aforesaid qualifications and is
such two appraisers cannot, within thirty (30) days after the appointment of the
second appraiser, agree upon the determination hereinabove required, then they
shall select a third appraiser which third appraiser shall have the aforesaid
qualifications, and if they fail so to do within forty (40) days after the
appointment of the second appraiser they shall notify the parties hereto, and
either party shall thereafter have the right, on notice to the other, to apply,
for the appointment of a third appraiser to the chapter of the American
Arbitration Association or its successor organization located in the
metropolitan area in which the Property is located or to which the Property is
proximate or if no such chapter is located in such metropolitan area, in the
metropolitan area closest to the Property in which such a chapter is located.
Each appraiser shall render its decision as to the Fair Market Value of the
Property in question within thirty (30) days after the appointment of the third
appraiser and shall furnish a copy thereof to the Guaranteed Party and
Guarantor. The Fair Market Value of the Property shall then be calculated as the
average of (i) the Fair Market Value determined by the third appraiser and (ii)
whichever of the Fair Market Values determined by the first two appraisers is
closer to the Fair Market Value determined by the third appraiser; provided,
however, that if the Fair Market Value determined by the third appraiser is
higher or lower than both Fair Market Values determined by the first two
appraiser, such Fair Market Value determined by the third appraiser shall be
disregarded and the Fair Market Value of the Property shall then be calculated
as the average of the Fair Market Value determined by the first two appraisers.
The Fair Market Value of a Property as so determined shall be binding and
conclusive upon the Guaranteed Party and Guarantor. Each party shall bear the
cost of its own appraiser and the cost of appointing, and the expenses of, the
third appraiser shall be shared equally by the Guaranteed Party and Guarantor.

                  2. Waivers. Other Agreements.

         The Guaranteed Party is hereby authorized, without notice to demand
upon Guarantors, which notice or demand is expressly waived hereby, and without
discharging or otherwise affecting the enforceability of the obligations of the
Guarantors hereunder (which shall remain absolute and unconditional
notwithstanding any such action or omission to act), from time to time to:

                  (i) waive or otherwise consent to noncompliance with any
         provision of the Note or Mortgage, or any part thereof, or any other
         instrument or agreement in respect of the Guaranteed Obligations now or
         hereafter executed by Maker or any other person and delivered to the
         Guaranteed Party, except that Maker shall not extend the time for
         payment of the Guaranteed Obligations by Maker;

                  (ii) accept partial payments on the Guaranteed Obligations by
         Maker;

                  (iii) receive, take and hold additional security or collateral
         for the payment of the Guaranteed Obligations or for the payment of
         this Guarantee, or for the payment of any other guarantees of the
         Guaranteed Obligations, and exchange, enforce, waive, substitute,
         liquidate, terminate, abandon, fail to perfect, subordinate, transfer,
         or otherwise alter or release any such additional security or
         collateral;

                  (iv) apply any and all such security or collateral and direct
         the order or manner of sale thereof as the Guaranteed Party may
         determine in its sole discretion;

                  (v) settle, release, compromise, collect or otherwise
         liquidate the Guaranteed Obligations or accept, substitute, release,
         exchange or otherwise alter, affect or impair any Mortgage or any other
         security or collateral for the Guaranteed Obligations or any other
         guarantee therefore, in any manner;

                  (vi) add, release or substitute any one or more other
         guarantors, makers or endorsers of the Guaranteed Obligations and
         otherwise deal with Maker or any other guarantor as the Guaranteed
         Party may elect in its sole discretion; and

                  (vii) apply any and all payments or recoveries from Maker,
         Guarantors or from any other guarantor of the Guaranteed Obligations,
         to such of the Guaranteed Obligations as the Guaranteed Party in its
         sole discretion may determine, whether such Guaranteed Obligations are
         secured or unsecured or guaranteed or not guaranteed by others.

                                      -5-


                  3. Miscellaneous.

         A. Notwithstanding anything in this Guarantee to the contrary, Lender
shall be required first to seek recourse and resort against Borrower and any and
all collateral (other than this Guarantee) given to Lender as security for the
Note prior to Lender's having recourse to or the right to exercise any remedies
against the Guarantors under this Guarantee. Any and all amounts received as a
result of Lender's having sought such recourse and resort shall reduce (on a
dollar-for-dollar basis) the Guaranteed Amount and the amount for which
Guarantors are liable for any and all other sums hereunder; it being agreed by
the parties hereto that the Guarantors shall only be liable to the extent there
remains unpaid any Guaranteed Amount or any other sums guaranteed by the
Guarantors hereunder after Lender has realized upon and resorted to the assets
of Borrower and all collateral (other than this Guarantee) given to Lender as
security for the Note.

         B. This Guarantee is binding on the Guarantors and their successors and
assigns, and insures to the benefit of the Guaranteed Party.

         C. No delay on the part of the Guaranteed Party in the exercise of any
right or remedy shall operate as a waiver thereof, and no single or partial
exercise or waiver by the Guaranteed Party of any right or remedy shall preclude
any further exercise thereof, nor shall any modification or waiver of any of the
provisions of this Guarantee be binding upon the Guaranteed Party, except as
expressly set forth in a writing duly signed or delivered by the Guaranteed
Party or on the Guaranteed Party's behalf by an authorized officer or agent of
the Guaranteed Party. The Guaranteed Party's failure at any time or times
hereafter to require strict performance by Maker, Guarantors or any other person
of any of the provisions, warranties, terms and conditions contained in any
security agreement, agreements, guarantee, instrument or document now or at any
time or times hereafter executed by Maker or Guarantors or delivered to the
Guaranteed Party shall not waive, affect or diminish any right of the Guaranteed
Party at any time or times hereafter to demand strict performance thereof and
such right shall not be deemed to have been waived by any act or knowledge of
the Guaranteed Party, its agents, officers, or employees, unless such waiver is
contained in an instrument in writing signed by an officer or agent of the
Guaranteed Party and directed to Maker or Guarantors, or either of them (as the
case may be) specifying such waiver. No waiver by the Guaranteed Party of any
default shall operate as a waiver of any other default or the same default on a
future occasion, and no action by the Guaranteed Party permitted hereunder shall
in any way affect or impair the Guaranteed Party's rights or the obligations of
Guarantors under this Guarantee.

                                      -6-


         D. This Guarantee shall be interpreted and the rights and liabilities
of the parties hereto determined in accordance with the laws (other than the
conflicts of law provisions) of the State of New York.

         E. This Guarantee contains all the terms and conditions of the
agreement between the Guaranteed Party and Guarantors. The terms and provisions
of this Guarantee may not be waived, altered, modified or amended except in
writing duly executed by the party to be charged thereby.

         F. Any notice shall be directed to the parties at the following
addresses:

                        If to Guarantors:

                        If to the Guaranteed Party:
