P. Robert Moya, our Chief Administrative Officer, Executive Vice President, General Counsel and Secretary, commenced his employment with us on October 10, 2002. Prior to that time, he was a partner in the law firm of Quarles & Brady LLP (ÒQuarlesÓ), which provided legal services to us during 2003. As contemplated by the terms of his employment agreement with us, Mr. Moya remained a partner of Quarles until September 30, 2003 in order to provide an orderly transition of his prior legal practice. He was compensated by Quarles during this transition period on the basis of various factors associated with the transition, including, among other things, revenues received from his former clients. However, Mr. Moya specifically has not and will not receive any compensation from Quarles directly or indirectly based on the amount of revenues paid to Quarles by us or our affiliates in respect of any services provided to us from and after October 1, 2002. We also believe the amounts paid to Quarles for legal services are as advantageous to us as we would obtain in an armÕs length transaction with a similar law firm.
