        <footnote id="F1">The Form 4 filed on May 22, 2015 contained a typographical error that inadvertently overstated the number of Non-qualified Stock Options that were exercised by 2,000 and understated the number of Incentive Stock Options that were exercised by 2,000.  This amendment corrects this error to reflect those exercises and both the Non-qualified Stock Options and Incentive Stock Options that remained beneficiallly owned.</footnote>
