statement setting forth the nature of the dispute, the amount involved, if 
any, and the remedy sought, and file with the appropriate office of the 
American Arbitration Association three copies of the notice and three copies 
of the arbitration provision of this Agreement, together with the appropriate 
filing fee as provided in the Schedule on page 21 of the AAA Commercial Rules 
as Amended and Effective on November 2, 1993.

The AAA shall give notice of such filing to the respondent which may file an 
answering statement in duplicate with the AAA within ten days after notice

copy of the answering statement to the claimant. If a counterclaim is 
asserted, it shall contain a statement setting forth the nature of the 
counterclaim, the amount involved, if any, and the remedy sought. If a 
counterclaim is made, the appropriate fee shall be forwarded to the AAA with 
the answering  statement. If no answering statement is filed within the 
stated time, it will be treated as a denial of the claim. Failure to file an 
answering statement shall not operate to delay the arbitration.

revised by the provisions herein, shall govern these proceedings. The 
arbitration shall be conducted by three arbitrators, one selected by each

mediation administered by the American Arbitration Association under its
