Pursuant to the instructions relating to the Exhibits in Item 601(b)(4)(iii) of Regulation S-K, MWBC hereby agrees to furnish the Commission, upon request, copies of instruments and agreements defining the rights of holders of its long-term debt and of the long-term debt of its consolidated subsidiaries, which are not being filed as exhibits to the Form 10-K.

Very truly yours,
