                        (ii)    the commencement of any proceedings by either or

                        (iv)    an involuntary bankruptcy or insolvency

        (which shall include, but not be limited to, any creditor or claimant

        concert with either or both of the Existing Owners) objects to a motion

                (the obligations set forth in this Section 1(a) are collectively

                (b)     The obligations, covenants, agreements and duties of
Guarantor under this Guaranty shall in no way be affected or impaired by reason
of the occurrence, from time to time, of any of the following with respect to
the Agreement, the Partnership Agreement, this Guaranty or any other documents
entered into in connection with the transactions contemplated by the Agreement
(collectively, the "Documents"), even though notice with regard to the following
may not have been given to, or received by, Guarantor, or the further consent of
Guarantor with regard to the following may not have been obtained:

                                        2


                        (i)     The waiver of the performance or observance by
        either or both of the Existing Owners or Guarantor of any agreement,
        covenant, term or condition to be performed or observed by it;

                        (ii)    The extension of the time for the payment of any
        sums owing or payable under the Documents or the time for the
        performance of any other obligation under or arising out of or on
        account of the Documents;

                        (iii)   The supplementing, modification or amendment
        (whether material or otherwise) of any of the Documents or any of the
        obligations of either or both of the Existing Owners or Guarantor, as
        applicable, set forth in any of the Documents;

                        (iv)    Any failure, omission, delay or lack on the part
        of the Cedar Group, or any member thereof, to enforce, assert or
        exercise any right, power or remedy conferred on such person in or by
        virtue of any of the Documents, or any action on the part of any of the
        Cedar Group granting indulgence or extension in any form;

                        (v)     Any payment made on the Obligations, whether
        made by either or both of the Existing Owners, Guarantor or any other
        person, which is required to be refunded pursuant to any bankruptcy or
        insolvency law; it being understood that no payment so refunded shall be
        considered as a payment of any portion of the Obligations, nor shall it
        have the effect of reducing the liability of Guarantor hereunder;

                        (vi)    The death of Guarantor; or

                        (vii)   The release of either or both of the Existing
        Owners from the performance or observance of any of the agreements,
        covenants, terms or conditions contained in any of the Documents by
        operation of law or otherwise.

                (c)     Guarantor hereby waives diligence and all demands,
protests, presentments and notices of every kind and nature, including, but not
limited to, notices of presentment, demand for payment or performance, protest,
notice of default or nonpayment, notice of dishonor, notice of protest and
notice of acceptance of this Guaranty and the creation, renewal, extension,
modification or accrual of any of the obligations Guarantor has hereby
guaranteed.

                (d)     Guarantor hereby waives any and all legal requirements
that any of the Cedar Group institute any action or proceeding, at law or in
equity, against the Existing Owners, or anyone else, or exhausts its remedies
against the Existing Owners, or anyone else, in respect of the Obligations or in
respect of any other security held by any of the Cedar Group as a condition
precedent to bringing an action or proceeding against Guarantor under this
Guaranty. All rights and remedies afforded to the Cedar Group by reason of this
Guaranty are separate and cumulative rights and remedies and it is agreed that
no one of such rights or remedies, whether exercised by any of the Cedar Group
or not, shall be deemed to be an exclusion of any of the other rights or
remedies available to the Cedar Group and shall not limit or prejudice any other
legal or equitable right or remedy which the Cedar Group may have.

                                        3


                (e)     Guarantor understands that the exercise by the Cedar
Group of certain rights and remedies may affect or eliminate Guarantor's right
of subrogation against the Existing Owners and that Guarantor may therefore
incur partially or totally nonreimbursable liability hereunder. Nevertheless,
Guarantor hereby authorizes and empowers the Cedar Group, their respective
successors, endorsees and/or assigns, to exercise in its or their sole
discretion, any rights and remedies, or any combination thereof, which may then
be available, it being the purpose and intent of Guarantor that the obligations
hereunder shall be absolute, continuing, independent and unconditional under any
and all circumstances. In the event that Guarantor shall advance or become
obligated to pay any sums under this Guaranty or in the event that either or
both of the Existing Owners shall hereafter become indebted to Guarantor,
Guarantor agrees that Guarantor shall have no right of subrogation or
reimbursement against either or both of the Existing Owners, no right of
subrogation against any collateral or any security provided for in the
Documents, unless and until all amounts due under this Guaranty shall have been
paid in full and all of Guarantor's obligations under the Guaranty shall have
been fully performed. To the extent Guarantor's waiver of these rights of
subrogation or reimbursement as set forth in this Guaranty are found by a court
of competent jurisdiction to be void or voidable for any reason, Guarantor
agrees that its rights of subrogation and reimbursement against the Existing
Owners and the members thereof and Guarantor's rights of subrogation against any
collateral or security shall be junior and subordinate as to lien, time of
payment and in all other respects to the Cedar Group' rights against the
Existing Owners and the members thereof and to the Cedar Group' right, title and
interest in such collateral or security. Nothing herein contained is intended or
shall be construed to give Guarantor any right of subrogation in or under the
Documents or any right to participate in any way therein, notwithstanding any
payments made by Guarantor under this Guaranty, all such rights of subrogation
and participation being hereby expressly waived and released.

                (f)     Guarantor unconditionally waives any defense to the
enforcement of this Guaranty, including, without limitation:

                        (i)     the right to plead any and all statutes of
        limitations as a defense to Guarantor's liability under this Guaranty;
        and

                        (ii)    any defense based upon an election of remedies
        by any of the Cedar Group, including, but not limited to, remedies
        relating to real property or personal property security, which destroys
        or otherwise impairs the subrogation rights of Guarantor to proceed
        against either or both of the Existing Owners.

        2.      Covenants, Representations and Warranties

                (a)     Guarantor represents and warrants to each of the Cedar
Group that there is no action or proceeding either pending or threatened against
Guarantor before any court or administrative agency and no event has occurred
which might result in any material adverse change in the business or condition
of Guarantor or in the property of Guarantor which material and adverse change
would materially impair the ability of Guarantor to perform its obligations
hereunder.

                (b)     Guarantor represents and warrants to each of the Cedar
Group that neither the execution nor delivery of this Guaranty, nor fulfillment
of nor compliance with the terms and

                                        4


provisions hereof, will conflict with, or result in a material breach of the
terms, conditions or provisions of, or constitute a material default under, or
result in the creation of any lien, charge or encumbrance upon any property or
assets of Guarantor under any other material agreement or material instrument to
which Guarantor is now a party or by which Guarantor may be bound.

                (c)     Guarantor agrees to submit to personal jurisdiction in
the Commonwealth of Pennsylvania in any action or proceeding arising out of this
Guaranty. This Guaranty shall be construed and interpreted in accordance with
the laws of the Commonwealth of Pennsylvania, without giving effect to
Pennsylvania's principles of conflicts of law.

        3.      Miscellaneous

                (a)     All guaranties, covenants and agreements contained in
this Guaranty shall bind the respective successors and assigns of Guarantor and
shall inure to the benefit of the Cedar Group, and their respective successors
and assigns.

                (b)     Any notice required or permitted to be delivered herein
shall be deemed to be delivered (a) when received by the addressee if delivered
by courier service, (b) if mailed, two days after deposit in the United States
Mail, postage prepaid, certified mail, return receipt requested, (c) if sent by
recognized overnight service (such as US Express Mail, Federal Express, UPS,
Airborne, etc.), then one day after delivery of same to an authorized
representative or agency of the said overnight service or (d) if sent by a
telecopier, when transmission is received by the addressee with electronic or

                (c)     Guarantor hereby waives the right of trial by jury in
any litigation arising hereunder and also waives the right, in such litigation,
to interpose counterclaims or setoffs of any kind or description.

                (d)     In the event that any of the Cedar Group shall receive
any payments on account of any of the obligations hereby guaranteed, whether
directly or indirectly, and it shall subsequently be determined that such
payments were for any reason improper, or a claim shall be made against any of
the Cedar Group that the same were improper, and any of the Cedar Group either
voluntarily or pursuant to court order shall return the same, Guarantor shall be
liable, with the same effect as if the said payments had never been paid to or
received by any of the Cedar Group, for the amount of such repaid or returned
payments, notwithstanding the fact that payments may theretofore have been
credited on account of the obligations hereby guaranteed.

                (e)     No delay on the part of any of the Cedar Group in
exercising any power or right hereunder shall operate as a waiver thereof; nor
shall any single or partial exercise of any power or right hereunder or the
failure to exercise same in any instance preclude other or further exercise
thereof or the exercise of any other power or right; nor shall any of the Cedar
Group be liable for exercising or failing to exercise any such power or right;
the rights and remedies hereunder expressly specified are cumulative and not
exclusive of any rights or remedies which any of the Cedar Group may or will
otherwise have.

                (f)     This instrument represents the entire agreement between
the parties and may not be modified or amended except by a writing duly executed
by the party to be charged.

                (g)     In the event that any of the Cedar Group, for any reason
whatsoever, shall deem it necessary to refer this Guaranty to an attorney for
the enforcement thereof or of any rights hereunder, by suit or otherwise, there
shall be immediately due from Guarantor to such Other Partner(s), in addition to
the sums guaranteed by Guarantor under this Guaranty, reasonable attorneys' fees
and actual disbursements, together with all costs and expenses of such action,
which costs, expenses, fees and disbursement shall be deemed part of the
obligation hereunder.

                (h)     In the event that any provision of this Guaranty or the
application thereof to Guarantor or any circumstance in the jurisdiction
governing this Guaranty shall, to any extent, be invalid or unenforceable under
any applicable statute, regulation, or rule of law, then such provision shall be
deemed inoperative to the extent that it may conflict therewith and shall be
deemed modified to conform to such statute, regulation or rule of law, and the
remainder of this Guaranty and the application of any such invalid or
unenforceable provision to parties, jurisdictions, or circumstances other than
to whom or to which it shall be held invalid or

                                        6


unenforceable, shall not be affected thereby nor shall same affect the validity
or enforceability of any other provision of this Guaranty.
