        NOW, THEREFORE, in consideration of the foregoing and for good and
valuable consideration, the receipt and sufficiency of which are hereby

have the meanings assigned to such terms in the Employment Agreement.

Agreement is hereby amended to replace the date “May 31, 2007” with the date
“June 30, 2008.”

    (b)               Effective July 1, 2006, the first sentence of Section 2.3
of the Employment Agreement is hereby amended to replace the title “President”
with the title “Executive Vice President, Law Enforcement.”

    3.        Continued Effectiveness. Except as expressly amended hereby, the
Employment Agreement shall continue in full force and effect. Any references to
the “Agreement” in the Employment Agreement or to the words hereof, hereunder or

County of Larimer or, if it has or can acquire jurisdiction, in the United
States District Court located in Denver, Colorado, and each of the parties
consents to the jurisdiction of such courts (and of the appropriate appellate
