each Loan is made, the maturity date therefor and each payment of principal with
respect thereto on the schedules annexed hereto and made a part hereof, or on
continuations thereof which shall be attached hereto and made a part hereof;
provided, that any failure to endorse such information on such schedule or
continuation thereof shall not in any manner affect any obligation of the
Company under the Credit Agreement and this Promissory Note (the "Note").

assignment or transfer of this Note shall have been accepted by the Agent and
recorded in the Register as provided in Section 10.07(c) of the Credit

Agreement, among other things, contains provisions for acceleration of the
maturity hereof upon the happening of certain stated events and also for
prepayments on account of principal hereof prior to the maturity hereof upon the
terms and conditions therein specified.

            No reference herein to the Credit Agreement and no provision of this
Note or the Credit Agreement shall alter or impair the obligations of the
Company, which are absolute and unconditional, to pay the principal of and
interest on this Note at the place, at the respective times, and in the currency
herein prescribed.

            THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
