day period following the date of the final prospectus (the "Lock-Up Period").
Mr. Neilsen also agreed not to exercise and to waive any registration rights
during the Lock-Up Period.

                             ):ss.
COUNTY OF CLARK              )

        I, Janet Catron, Notary Public in and for said county and state, do
hereby certify that Craig H. Neilsen personally appeared before me and is known
or identified to me to be the person who executed the foregoing instrument.
Craig H. Neilsen, who being unable due to physical incapacity to sign his name
or offer his mark, did direct Connie Wilson, in his presence, as well as my own,
to sign his name to the foregoing document. Craig H. Neilsen, after viewing his
name as signed by Connie Wilson, thereupon adopted the signatures as his own by
acknowledging to me his intention to so adopt them as if he had personally
executed the same.

        IN WITNESS WHEREOF, I have hereunto set my hand and official seal this
14th day of December, 2001.
