As co-trustee, the reporting person shares investment and voting rights on the shares in the trust with Wachovia and his sister.</footnote><footnote id="F4">Trust FBO one of reporting person's children in which the reporting person has sole voting power.  An amended Form 5 filed December 2002 indicated that 56,632 shares held in two seperate trusts (113, 264 total shares) for the benefit of Mr. Monk's children should not have been reported as beneficially owned by Mr. Monk.  That form was incorrect, and each subsequent Form 5 filed August 1, 2003 and Form 4 filed August 28, 2003 by Mr. Monk incorrectly failed to include those 113,264 shares.</footnote></footnotes><remarks/><ownerSignature><signatureName>Albert C.
