D. All capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the Lease.

In consideration of the premises and other good and valuable consideration, the receipt of and sufficiency of which are hereby acknowledged, and in order to induce the Lessor to enter into the Lease, Guarantor hereby agrees as follows:

1. Guaranty. Guarantor unconditionally, absolutely and irrevocably guarantees the punctual and complete payment and performance when due to Lessor of all Monetary Obligations, including, without limitation, Rental, taxes, insurance premiums, impounds, reimbursements, late charges, default interest, damages, indemnity obligations and all other amounts, costs, fees, expenses and charges of any kind or type whatsoever, which may or at any time be due to Lessor under or pursuant to the documents listed on Schedule I attached hereto (collectively, the “Documents”). Guarantor also unconditionally guarantees the truthfulness and accuracy of all representations, warranties and certifications of Lessee, the satisfaction of all conditions by Lessee and the full and timely performance of all obligations to be performed by Lessee, under or pursuant to the Documents (the matters which are guaranteed pursuant to this section are hereinafter collectively referred to as the “Obligations”). The obligations of Guarantor under this Guaranty are primary, joint and several and independent of the obligations of Lessee and any and every other guarantor of the Obligations, and a separate action or actions may be brought and executed against Guarantor or any other such guarantor, whether or not such action is brought against Lessee or any other such guarantor and whether or not Lessee or any other such guarantor be joined in such action or actions.

2. Waivers. This is an absolute and unconditional guaranty of payment and performance and not of collection and Guarantor unconditionally (a) waives any requirement

3. Continuing Guaranty. This Guaranty is a continuing guaranty, and the obligations, undertakings and conditions to be performed or observed by Guarantor under this Guaranty shall not be affected or impaired by reason of the happening from time to time of the following with respect to the Documents, all without notice to, or the further consent of, Guarantor: (a) the waiver by Lessor of the observance or performance by Lessee or Guarantor of any of the obligations, undertakings, conditions or other provisions contained in any of the Documents, except to the extent of such waiver; (b) the extension, in whole or in part, of the time for payment of any amount owing or payable under the Documents; (c) the modification or amendment (whether material or otherwise) of any of the obligations of Lessee under, or any other provisions of, any of the Documents, except to the extent of such modification or amendment; (d) the taking or the omission of any of the actions referred to in any of the Documents (including, without limitation, the giving of any consent referred to therein); (e) any failure, omission, delay or lack on the part of Lessor to enforce, assert or exercise any provision of the Documents, including any right, power or remedy conferred on Lessor in any of the Documents or any action on the part of Lessor granting indulgence or extension in any form; (f) the assignment to or assumption by any third party of any or all of the rights or obligations of Lessee under all or any of the Documents; (g) the release or discharge of Lessee from the performance or observance of any obligation, undertaking or condition to be performed by Lessee under any of the Documents by operation of law, including any rejection or disaffirmance of any of the Documents in any bankruptcy or similar proceedings; (h) the receipt and acceptance by Lessor or any other Person of notes, checks or other instruments for the payment of money and extensions and renewals thereof; (i) any action, inaction or election of remedies by Lessor which results in any impairment or destruction of any subrogation rights of Guarantor, or any rights of Guarantor to proceed against any other Person for reimbursement; (j) any setoff, defense, counterclaim, abatement, recoupment, reduction, change in law or any other event or circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor, indemnitor or surety under the laws of the Commonwealth of Pennsylvania, the states in which the Properties are located or any other jurisdiction; and (k) the

renewal of any of the Obligations. Notwithstanding the foregoing or anything contained in this Guaranty to the contrary, Guarantor shall have the right to assert all claims and defenses hereunder and under the Lease to the extent that Lessee is permitted such claim or defense, with respect to the Lease, by applicable law.

4. Representations and Warranties. Guarantor represents and warrants to Lessor that: (a) neither the execution nor delivery of this Guaranty nor fulfillment of nor compliance with the terms and provisions hereof will conflict with, or result in a breach of the terms or conditions of, or constitute a default under, Guarantor’s articles of incorporation, bylaws, or any standing resolution of its board of directors or, to Guarantor’s knowledge, any agreement to which Guarantor is a party, or result in the creation of any lien, charge or encumbrance upon any property or assets of Guarantor, which conflict, breach, default, lien, charge or encumbrance could result in a material adverse change in the financial condition of Guarantor; (b) no further consents, approvals or authorizations are required for the execution and delivery of this Guaranty by Guarantor or for Guarantor’s compliance with the terms and provisions of this Guaranty other than those which have been duly obtained by Guarantor and are in full force and effect; (c) this Guaranty is the legal, valid and binding agreement of Guarantor and is enforceable against Guarantor in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, liquidation, reorganization and other laws affecting the rights of creditors generally and subject to general principles of equity; (d) Guarantor has the full power, authority, capacity and legal right to execute and deliver this Guaranty, and the parties executing this Guaranty on behalf of Guarantor are fully authorized and directed to execute the same to bind Guarantor; (e) Guarantor is not, and if Guarantor is a “disregarded entity,” any owner of the disregarded entity is not, a “nonresident alien,” “foreign corporation,” “foreign partnership,” “foreign trust,” “foreign estate,” or any other “person” that is not a “United States person,” as those terms are defined in the U.S. Internal Revenue Code and the regulations promulgated thereunder; (f) Guarantor is not a party with whom a citizen of the United States is prohibited from engaging in transactions by any trade embargo, economic sanction or other prohibition of United States law, regulation or Executive Order of the President of the United States; (g) all financial statements and other information relating to Guarantor heretofore delivered to Lessor are true, correct and complete in all material respects as of the date they were furnished to Lessor, and to the extent not filed with the Securities and Exchange Commission and publicly available on EDGAR, Guarantor will furnish Lessor, within forty five (45) days after the end of each fiscal quarter of Guarantor and within one hundred twenty (120) days after the end of each fiscal year of Guarantor, complete financial statements of Guarantor, including a balance sheet, profit and loss statement, statement of changes in financial condition and all other related schedules for the fiscal period then ended (in addition to any reporting requirements of Guarantor set forth in Section 9.03 of the Lease); (h) during the term of this Guaranty, Guarantor will not transfer or dispose of all or substantially all of Guarantor’s assets except (1) in the ordinary course of business for fair consideration in arm’s length transactions, or (2) to the extent that such transfer or disposition does not reasonably impair Guarantor’s ability to satisfy the Obligations; and (i) the Documents are conclusively presumed to have been signed in reliance on this Guaranty, and the assumption by Guarantor of Guarantor’s obligations under this Guaranty results in direct financial benefit to Guarantor. Guarantor understands that Lessor is relying on the representations and warranties of Guarantor, and Guarantor represents that such reliance is reasonable.

5. Nature of Guaranty. This Guaranty shall commence upon execution and delivery of the Lease and shall continue in full force and effect until all of the Obligations are paid and performed in full and are not subject to any right of extension by Lessee; provided,

however, in the event the Lease is assigned as permitted under the Lease, and in connection therewith, Lessor receives a replacement Guaranty that is acceptable to Lessor in its reasonable discretion, then Guarantor’s liability shall be limited to the obligations of Lessee accruing prior to the assignment and effective date of the replacement guaranty. The Obligations shall not be considered fully paid, performed and discharged unless and until all payments by Lessee to Lessor are no longer subject to any right on the part of any Person whomsoever, including but not limited to Lessee, Lessee as a debtor-in-possession and/or any trustee in bankruptcy, to disgorge such payments or seek to recoup the amount of such payments or any part thereof. This Guaranty shall remain in full force and effect and continue to be effective upon an Insolvency Event. This Guaranty shall continue to be effective or be reinstated, as applicable, if at any time payment and performance of the Obligations, or any part thereof, are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by Lessor, whether as a “voidable preference,” “fraudulent conveyance” or otherwise, all as though such payment or performance had not been made. In the event that any payment of the Obligations, or any part thereof, is rescinded, reduced, restored or returned, the Obligations shall be reinstated and deemed reduced only by such amount paid to Lessor and not so rescinded, reduced, restored or returned.

6. Subordination. Notwithstanding any provision contained in this Guaranty, in the event that Guarantor shall have any claims against Lessee, upon the occurrence and continuation of an Event of Default under the Lease, any indebtedness of Lessee held by Guarantor shall be automatically subordinated to the indebtedness of Lessee to Lessor, including, without limitation, any and all amounts due to Lessor under the Lease. In the event Guarantor should receive from Lessee any payments in partial or full satisfaction of such indebtedness of Lessee to Guarantor following written request from Lessor after the occurrence and during the continuation of an Event of Default under the Lease, Guarantor agrees to hold such amount received in trust for Lessor and to pay the same to Lessor, but only to the extent of the Obligations then owing by Lessee to Lessor.

7. Intentionally Deleted.

8. Attorneys’ Fees and Costs. In addition to the amounts guaranteed under this Guaranty, Guarantor agrees to pay (a) all of Lessor’s Costs, and (b) interest (including postpetition interest to the extent a petition is filed by or against Lessee under the Bankruptcy Code) at the Default Rate on any Obligations not paid when due, subject to applicable notice and cure provisions. Guarantor hereby agrees to indemnify and hold harmless Lessor for, from and against all Losses suffered or occasioned by the failure of Lessee to satisfy its obligations under the Documents. The agreement to indemnify Lessor contained in this Section shall be enforceable notwithstanding the invalidity or unenforceability of the Documents or any of them or the invalidity or unenforceability of any other paragraph contained in this Guaranty. All moneys available to Lessor for application in payment or reduction of the liabilities of Lessee under the Documents may be applied by Lessor to the payment or reduction of such liabilities of Lessee, in such manner, in such amounts and at such time or times as Lessor may elect.

9. Notice. All notices, demands, designations, certificates, requests, offers, consents, approvals, appointments and other instruments given pursuant to this Guaranty (collectively called “Notices”) shall be in writing and given by any one of the following: (a) hand delivery; (b) express overnight delivery service; (c) certified or registered mail, return receipt requested; or (d) electronic mail message, and shall be deemed to have been delivered upon (i) receipt, if hand delivered, (ii) the next Business Day, if delivered by a reputable express overnight delivery service; (iii) the third Business Day following the day of deposit of such notice

10. Governing Law. This Guaranty is delivered in the Commonwealth of Pennsylvania, and it is the intent of Guarantor and Lessor that this Guaranty shall be deemed to be a contract made under and governed by the internal laws of the Commonwealth of Pennsylvania, without regard to its principles of conflicts of law. For purposes of any action or proceeding involving this Guaranty, Guarantor submits to the jurisdiction of all federal and state courts located in the Commonwealth of Pennsylvania and consents that Guarantor may be served with any process or paper by registered mail or by personal service within or without the Commonwealth of Pennsylvania in accordance with applicable law. Guarantor waives and agrees not to assert in any such action, suit or proceeding that Guarantor is not personally subject to the jurisdiction of such courts, that the action, suit or proceeding is brought in an inconvenient forum or that venue of the action, suit or proceeding is improper. Nothing contained in this section shall limit or restrict the right of Lessor to commence any proceeding in the federal or state courts located in the states in which the Properties are located and/or where Guarantor maintains Guarantor’s residence or chief executive office to the extent Lessor deems such proceeding necessary or advisable to exercise remedies available under the Documents.

11. Acknowledgement of Lease. Guarantor shall not challenge the validity, enforceability or characterization of the Transaction, and Guarantor shall support the intent of Guarantor, Lessee and Lessor that the Lease does not create a joint venture, partnership, equitable mortgage, trust, trust agreement, security interest or the like. Guarantor

acknowledges that Lessor did not prepare or assist in the preparation of any of the projected financial figures used by Lessee in analyzing the economic viability and feasibility of the Transaction.

12. Independent Rights. All of Lessor’s rights and remedies under the Documents and this Guaranty are intended to be distinct, separate and cumulative and no such right and remedy is intended to be in exclusion of or a waiver of any of the others.

Guarantor acknowledges and agrees that (a) Lessor may collaterally assign all of its right, title and interest under the Lease and this Guaranty to a lender; and (b) upon the exercise of any lender’s remedies set forth in related loan documents, all of the rights, powers and privileges of Lessor shall be deemed the rights, powers and privileges of such lender and such lender shall be entitled to exercise all of the rights and remedies of “Lessor” under this Guaranty, the Lease and such loan documents. Guarantor hereby consents to, and no further consent by Guarantor shall be required for, any further assignment of rights of Lessor hereunder or in connection with any transfer by Lessor. All notices, certificates, reports or other information required to be delivered to Lessor under this Guaranty shall be delivered simultaneously to such lender, provided that Lessor provides Guarantor with advance written notice and the address of such lender.

No sales, participations, assignments, transfers or other dispositions of any agreement governing or instrument evidencing the Obligations or any portion thereof or interest therein shall in any manner affect the rights of Lessor or its successors and assigns hereunder. Guarantor may not assign, sell, hypothecate or otherwise transfer any interest in or obligation under this Guaranty.

For purposes hereof, “Constituent Person” means any direct member, partner or shareholder in Guarantor and any individual, corporation, partnership, limited liability company, joint venture, estate, trust, or unincorporated association, that, directly or indirectly through one or more other partnerships, limited liability companies, corporations or other entities is a member, partner or shareholder in Guarantor or owns an interest in Guarantor.

16. Severability. If any provision of this Guaranty is unenforceable, the enforceability of the other provisions shall not be affected and they shall remain in full force and

effect. Guarantor agrees to take such reasonable action and to sign such other reasonable documents as may be reasonably required to carry out the intent of this Guaranty. This Guaranty may be executed in one or more counterparts, each of which shall be deemed an original.
