Item 5.02.  Departure of Directors or Certain  Officers;  Election of Directors;
Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

          (e) On December 4, 2009, the Compensation and Human Resources
Committee (the "Committee") of the Board of Directors of Keithley Instruments,
Inc. (the "Company") approved the Company's performance share award program
covering fiscal years 2010 through 2012 (the "Performance Share Program"), which
provides for performance awards to be issued under the Company's Amended and
Restated 2002 Stock Incentive Plan or 2009 Stock Incentive Plan (in each case,
the "Plan"). Performance award units entitle participants to receive a specified
number of the Company's common shares based on the degree to which performance
goals have been achieved as of the end of the performance period.

         The performance period, goals and payout terms established by the
Committee for the Performance Share Program were as follows:

     o    The performance period began on the grant date of December 4, 2009 and
          ends on  September  30,  2012,  the last day of the third  fiscal year
          following the grant date.

     o    The  performance  measure  for  the  awards  is  the  Company's  Total
          Shareholder  Return (TSR) growth rate compared to that of companies in
          the  Russell  Microcap  Index.  If  there  have  been  changes  in the
          companies  that are  included in the index as of the  beginning of the
          measurement period compared to the end of the measurement  period, for
          example, as a result of acquisitions,  mergers,  bankruptcies or going
          private transactions,  that have a significant impact on the resulting
          TSR growth rate, the Committee in its sole  discretion may exclude the
          impact of one or more of such companies' TSR from the index group.

     o    The TSR growth rate will be calculated as the difference  between each
          company's  average  share price at the  beginning  of the  measurement
          period  compared to each  company's  average share price at the end of
          the measurement period, plus the cumulative dividends paid during that
          period.  A thirty calendar day average share price will be used at the
          beginning and end of the measurement period for this calculation.

     o    The common shares subject to the performance awards will be earned and
          issued at the target (100%) payout amounts if the Company's TSR growth
          rate  is at  median  of the  companies  in the  index.  Actual  payout
          percentages  will be based  on  linear  slope  with a  minimum  payout
          threshold at 25th  percentile  and maximum payout of 200% of target at
          75th percentile.  Each percentile increase above 25th will equate to a
          4% payout increase, as demonstrated in the table below.


                                                                                             

                                                                                                      (greater than) (greater than)
                                     (greater than) 25th - (greater than) 35th - (greater than) 50th   65th - (less    75th - (less
                   0 - (less than or  (less than or equal    (less than or equal   - (less than or     than or equal  than or equal
Percentile            equal to) 25th        to) 35th               to) 50th         equal to) 65th       to) 75th        to) 100th
% Payout of Target         0%               4% - 40%             44% - 100%          104% - 160%       164% - 200%         200%


         The awards were issued pursuant to the terms of the Plan and the form
of performance award agreement also approved by the Committee on December 4,
2009 and filed herewith as Exhibit 10.1. The award agreement provides that the
shares, if any, to be paid out under the award will be issued by December 31,
2012 and are subject to set off and recoupment for certain claims that the
Company may have against an award recipient within a three-year period following
the end of the recipient's employment with the Company. In addition, if an award
recipient terminates or the Company terminates his or her employment before the
end of the performance period, the entire award will be forfeited unless the
termination is due to retirement upon satisfactory conditions. Such retirees
will receive a pro rata payout based on the TSR growth achieved by the Company
at the end of the performance period, but pro rated to the number of the days in
the period that the retiree was employed by the Company.
