Title:         SERIAL NUMBER DESIGNATION

Policy:   All products manufactured by the company will be
          assigned a unique serial number identification to
          provide traceability of products for recalls, warranty
          periods, etc.

Purpose:  This procedure describes how serial numbers are
          determined and assigned to products.

Scope:    This procedure applies to all products manufactured by
          the company.


Procedures:

1.0  Serial Numbering

1.1  The serial number is used in conjunction with the products
     model number for identification.  Therefore no reference to
     product classifications are incorporated into the serial
     number.

     The serial number will be based upon the completion date of
     manufacture for the product and will use the Julian date
     series for serial number determination.  Each day of the
     calendar year beginning with January 1st is assigned
     successive increments from 1 to 365.  For example, May 26th
     is the 146th day of the year.

     The serial number is coded to prevent public disclosure of
     the company's production volumes or shelf-life concerns of
     products shipped to customers.  The serial number consist of
     eight (8) digits assigned as follows:

     Sequence  1st, 2nd  3rd, 4th, 5th       6th, 7th, 8th
     Digit           X   X     X    X    X         X    X    X

               Last Digits of Production Day of Year   Daily
Production
               Current Year                  Number


     For example, the 35th unit produced on May 26, 1990 would be
     represented by the following serial number - "90146035"


1.2  The serial number should be assigned on the date of initial
     completion of the product prior to inspection to assist in
     implementation of product recalls, etc.
