Nothing herein contained shall be construed as prohibiting the parties respectively from changing the place at which notice is thenceforth to be given, but no such change shall be effective unless and until it shall have been accomplished by written notice given in the manner set forth in this provision.

    Section 10.2    No Waivers. No failure or delay by the Lender in exercising any right, power or privilege hereunder or under the Note shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

    Section 10.3    Expenses. The Borrower shall pay (a) all out-of-pocket expenses of the Lender, including the reasonable fees and disbursements of counsel for the Lender, in connection with the preparation and administration of this Agreement, any waiver or consent hereunder or any amendment hereof or any Default or alleged Default hereunder and (b) if an Event of Default occurs, all out-of-pocket expenses incurred by the Lender, including reasonable fees and disbursements of counsel, in connection with such Event of Default and collection and other enforcement proceedings resulting therefrom. Borrower shall indemnify the Lender against any transfer taxes, documentary taxes, assessments or charges made by any Governmental Authority by reason of the execution and delivery of this Agreement, the Note or the other Loan Documents.

    Section 10.4    Right of Set-Off. Without constituting a retention of Collateral in satisfaction of an obligation within the meaning of Section 9620 of the UCC, upon the occurrence of any Event of Default, the Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by the Lender to or for the credit or the account of the Borrower against any and all of the obligations now or hereafter existing under this Agreement, the Note or any other Loan Document, irrespective of whether or not the Lender shall have made any demand hereunder or under the Note and although such obligation may be unmatured. The rights of the Lender under this Section 10.4 are in addition to other rights and remedies (including, without limitation, other rights of set-off) which the Lender may have. Borrower agrees, to the fullest extent it may effectively do so under applicable law, that any holder of a participation in any Note may exercise rights of set-off or counterclaim or other rights with respect to such participation as fully as if such holder of a participation were a direct creditor of the Borrower in the amount of such participation. The Lender agrees to notify the Borrower promptly after it exercises any such right of set-off.

            (a)    The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that the Borrower may not assign or otherwise transfer any of its rights under this Loan without the prior written consent of the Lender.

            (b)    The Lender may at any time grant to one or more Lenders or other institutions (each a “Participant”) participating interests in the Credit Facility or in the Note. In the event of any such grant by the Lender of a participating interest to a Participant, whether or not upon notice to the Borrower, the Lender shall remain responsible for the performance of its obligations hereunder, and the Lender shall continue to deal solely and directly with the Borrower in connection with the Lender’s rights and obligations under this Agreement.

            (c)    The Lender may at any time assign all or any portion of its rights under this Agreement and the Note to a Federal Reserve lender.

The Borrower hereby irrevocably and unconditionally waives any objection, including without limitation, any objection to the laying of venue or based on the grounds of forum non conveniens which it now or hereafter may have to the bringing of any action or proceeding in such jurisdiction. The Borrower hereby agrees and consents that, in addition to any methods of service of process provided for under applicable law, all service of process in any such legal action or proceeding in any state court or any United States federal court may be made by certified or registered mail, return receipt requested, directed to the Borrower at its address for notice as provided in this Agreement, and service so made shall be complete five days after the same shall have been so mailed. Nothing herein shall affect the right of the Lender to bring proceedings against the Borrower in any other court or jurisdiction, nor the right of the Lender to serve process in any manner permitted by law.
