ITEM 5.02  DEPARTURE OF DIRECTORS OR CERTAIN  OFFICERS;  ELECTION OF  DIRECTORS;
           APPOINTMENT  OF  CERTAIN  OFFICERS;  COMPENSATORY  ARRANGEMENTS  OF
           CERTAIN OFFICERS

Fiscal Year 2008 Bonus Criteria

On  February  6, 2008,  the Human  Resources  and  Compensation  Committee  (the
"Committee") of the Registrant's  Board of Directors took the following  actions
with  respect to the  fiscal  year 2008  bonuses to be paid to the  Registrant's
executive  officers  after  the end of the  fiscal  year  2008.  Each  executive
officer's  bonus  target is  divided  between  two  plans:  (i) the  Performance
Compensation  Plan (the  "PCP")  and (ii) the  Incentive  Compensation  Plan For
Executive Officers (the "ICP"):

1.   Under the PCP,  the  Committee  approved  the fiscal  year 2008  evaluation
     criteria for the  determination of the actual PCP bonuses to be paid to the
     executive  officers  after the end of fiscal year 2008.  The Committee will
     evaluate and measure the performance of the executive officers based on the
     achievement of various  Registrant and individual  objectives,  weighted as
     follows:  cash flow - 40%;  Doble  Engineering  Company  sales and earnings
     before  interest and taxes (EBIT) - 20%;  proceeds from the  divestiture of
     the  Filtertek  businesses  - 10%;  and  individual  objectives  - 30%. The
     achievement  of each of  these  three  Registrant  objectives  is  measured
     utilizing a relevant matrix. The target multiplier under the PCP for fiscal
     2008 ranges from 0.2 to 2.0 times the bonus target.

2.   Under the ICP, the  Committee  modified  the fiscal year 2008  earnings per
     share (EPS) matrix, which is the evaluation criterion for the determination
     of the actual ICP bonuses to be paid to the  executive  officers  after the
     end of fiscal year 2008.  The modified EPS matrix for fiscal 2008 under the
     ICP has an EPS range from $1.45 to $1.97. The bonus target multiplier under
     the ICP for fiscal 2008 ranges from 0.2 to 2.0 times the bonus target.

Actual bonuses to be paid under each of the PCP and the ICP for fiscal year 2008
may vary from their  respective  bonus  targets:  (i) depending on the extent to
which  performance  exceeds  or falls  below the  fiscal  year  2008  evaluation
criteria  described in paragraph 1 above, in the case of the PCP; and (ii) based
upon the  application  of the fiscal  year 2008 ICP  earnings  per share  matrix
described in paragraph 2 above, in the case of the ICP.

Compensatory Arrangements For G.E. Muenster

Effective  February 11, 2008, the  Registrant's  Board of Directors  changed the
title of executive  officer G.E.  Muenster  (the  "executive")  from Senior Vice
President  and Chief  Financial  Officer to Executive  Vice  President and Chief
Financial Officer.

On February 6, 2008, the Committee took the following actions with regard to the
executive:

     1.   The  executive's  fiscal  year 2008 base  salary  was  increased  from
          $340,000 to $430,000.

     2.   The Committee,  under the PCP and the ICP jointly,  changed the fiscal
          year 2008  bonus  target for the  executive  from 30% to 35% of fiscal
          year 2008 total cash  compensation,  with such change to be  pro-rated
          effective as of February 1, 2008. As a result,  the executive's fiscal
          year 2008 bonus target was increased from $140,000 to $230,000.

     3.   The  executive's  current  employment  agreement,   as  amended,  (the
          "Employment Agreement") was further amended effective February 6, 2008
          to extend,  in the case of a termination as described below,  from one
          year to two years the period for which the executive  will receive (i)
          the  continuation  of his  then-current  base salary and bonus  (bonus
          calculated  using the annual  percentage  of base  salary for the last
          fiscal  year  prior  to  termination),  and (ii)  continuation  of his
          perquisites and certain employee  benefits.  Such a termination  would
          exist if the  executive's  employment is terminated by the  Registrant
          other than for cause,  or if the executive  terminates  his employment
          following certain actions by the Registrant, such as failing to comply
          with the Employment  Agreement,  materially  reducing the  executive's
          responsibilities   or  requiring  the  executive  to  relocate.   This
          amendment is furnished  herewith as Exhibit 10.1.  If the  executive's
          employment is  terminated  in connection  with a Change of Control (as
          defined), he will not receive the foregoing benefits, and will receive
          instead the benefits payable under the Registrant's Severance Plan.

          The  Employment  Agreement  became  effective on or about  November 1,
          1999.  It was  amended to extend  until  November  2, 2004,  and again
          amended on May 5, 2004 to provide  automatic renewal after November 2,
          2004 for  subsequent  one-year  periods  unless a six month  notice of
          non-renewal  is  given  by the  Registrant  or the  executive.  It was
          further  amended on  December  31,  2007 to provide  that the  amounts
          payable under the Employment  Agreement upon termination of employment
          would not be subject to Section 409A of the Internal Revenue Code.

          The Employment  Agreement  provides for a base salary of not less than
          the  executive's  fiscal  year  1999  base  salary,  as  increased  in
          accordance with the Registrant's  compensation  policy,  and an annual
          bonus.  The  executive is also  entitled to  participate  in any stock
          options,  restricted  stock or  performance  shares  awards  and other
          compensation  as the  Registrant's  Human  Resources and  Compensation
          Committee  shall  determine.  The  executive  is further  entitled  to
          participate  in  all  employee  benefit  programs  of  the  Registrant
          applicable to senior  executives,  and the Registrant will continue to
          provide  certain   perquisites,   including  financial  planning,   an
          automobile allowance and club membership.

          5.02 of the Registrant's Current Report on Form 8-K dated December 31,
          2007, which is incorporated herein by reference.
