Maker shall pay all reasonable costs and expenses incurred by or on behalf of Payee in connection with Payee's exercise of any or all of its rights and remedies under this Note, including, without limitation, reasonable attorneys' fees. 3. REPRESENTATIONS AND COVENANTS. 3.1 SINGLE PURPOSE ENTITY. Maker represents to Payee that Maker is and has at all times since its formation been a Single Purpose Entity. "Single Purpose Entity" shall mean an entity that exists solely for the purpose of acquiring, developing, financing, managing and owning the Property, that conducts business only in its own name, that does not engage in any business or have any assets unrelated to such purpose, that does not have any indebtedness other than that related to such purpose, that has its own separate books, records, and accounts (with no commingling of assets), that holds itself out as being an entity separate and apart from any other entity, and that observes partnership formalities independent of any other entity. 3.2 LEGAL EXISTENCE; NAME, ETC. Maker shall preserve and keep in full force and effect its existence as a Single Purpose Entity, franchises, rights and privileges under the laws of the state of its formation, and all qualifications, licenses and permits applicable to the ownership, use and operation of the Property. Maker shall not wind up, liquidate, dissolve, reorganize, merge, or consolidate with or into, or convey, sell, assign, transfer, lease, or otherwise dispose of all or substantially all of its assets, or acquire all or substantially all of the assets of the business of any Person. Maker shall conduct business only in its own name and shall not change its name, identity, or organizational structure unless Maker shall have obtained the prior written consent of Payee to such change. 4. MISCELLANEOUS. 4.1 WAIVER. The rights and remedies of Payee under this Note shall be cumulative and not alternative. No waiver by Payee of any right or remedy under this Note shall be effective unless in a writing signed by Payee. Neither the failure nor any delay in exercising any right, power or privilege under this Note will operate as a waiver of such right, power or privilege and no single or partial exercise of any such right, power or privilege by Payee will preclude any other or further exercise of such right, power or privilege or the exercise of any other right, power or privilege. To the maximum extent permitted by applicable law, (i) no claim or right of Payee arising out of this Note can be discharged by Payee, in whole or in part, by a waiver or renunciation of the claim or right unless in a writing, signed by Payee; (ii) no waiver that may be given by Payee will be applicable except in the specific instance for which it is given; and (iii) no notice to or demand on Maker will be deemed to be a waiver of any obligation of Maker or of the right of Payee to take further action without notice or demand as provided in this Note. Maker hereby waives presentment, demand, protest and notice of dishonor and protest. 4.2 NOTICES. Any notice required or permitted to be given hereunder shall be given in accordance with the Purchase Agreement. 4.3 SEVERABILITY. If any provision in this Note is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Note will remain in full force and effect. Any provision of this Note held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable. 4.4 GOVERNING LAW. This Note will be governed by the laws of the Commonwealth of Pennsylvania without regard to conflicts of laws principles. 4.5 PARTIES IN INTEREST. This Note shall bind Maker and its successors and assigns. This Note shall not be assigned or transferred by Payee without the express prior written consent of Maker, except by operation of law. 4.6 MAXIMUM INTEREST. Notwithstanding anything to the contrary contained in this Note, no interest shall accrue or be payable hereunder that is in excess of the maximum amount permitted under the applicable law relating to usury. IN WITNESS WHEREOF, intending to be legally bound, Maker has executed and delivered this Note as of date first above written. BELLEVUE PARTNERS, L.P. By: /S/Jay H. Lustig Name: Jay H.
