In addition, whether or not the proposed Offering is consummated and in addition to any fees payable to Sterne Agee pursuant to Section 3 above, the Company will reimburse Sterne Agee for all of its reasonable out-of-pocket expenses incurred in connection with, or arising out of, Sterne Agee’s activities under, or contemplated by, its engagement hereunder, including without limitation Sterne Agee’s travel costs, meals and lodging, photocopying, data processing fees and expenses, advertising and communications expenses, which will not exceed $100,000.
