Modification of Performance Share Awards under the Avocent Corporation 2005
---------------------------------------------------------------------------
Equity Incentive Plan and 2008 Inducement Equity Incentive Plan.
----------------------------------------------------------------

     The Avocent  Corporation  2005 Equity  Incentive Plan (the "2005 Plan") was
approved  by  stockholders  and was  filed  with  the  Securities  and  Exchange
Commission.  The  description of the 2005 Plan contained  herein is qualified in
its  entirety by  reference  to the full text of the amended  2005 Plan filed as
Exhibit  99.16  to the  Company's  Form  8-K on June  15,  2006  and the form of
agreements under the 2005 Plan filed as Exhibit 99.20 to the Company's Form 10-Q
on November 5, 2008.

     The Avocent  Corporation  2008 Inducement  Equity Incentive Plan (the "2008
Plan") was approved by the Company's Board of Directors,  and was filed with the
Securities and Exchange  Commission.  The description of the 2008 Plan contained
herein is qualified in its entirety by reference to the full text of the amended
2008 Plan filed as Exhibit 99.18 to the  Company's  Form 8-K/A on August 4, 2008
and the form of  agreements  under the 2008 Plan filed as  Exhibit  99.20 to the
Company's Form 10-Q on November 5, 2008.

     The  Company's  Compensation   Committee,   which  is  comprised  of  three
independent  non-employee  directors,  is the Administrator  under both the 2005
Plan and the 2008 Plan.

     Both the 2005 Plan and the 2008 Plan authorize the  Compensation  Committee
to determine the goals  applicable for  performance-based  awards.  Earlier this
year, the Compensation  Committee awarded performance shares for 2008 under both
the 2005 Plan and the 2008 Plan to the  Company's  executive  officers and other
employees at specified  targeted levels of the Company's  common stock price (as
measured on a moving average basis) on specific dates during a two-year  period.
The targeted  price levels  designated  were absolute  based on the economic and
financial  considerations in effect at the beginning of 2008, and these targeted
price  levels were not indexed to any peer group or market  index.  Depending on
the Company's stock price levels on specified dates during the two-year  period,
participants  would  earn  a  percentage  from  0% to  125%  of  their  targeted
performance-based   awards.   Any  performance   shares  actually  earned  by  a
participant, if and to the extent earned, would vest over three years.

     Given the current  declining  economic  environment  with the  accompanying
broad-based decline in global corporate stock prices, the Compensation Committee
concluded that the originally-specified  targeted levels of the Company's common
stock  price on  specified  dates  during  the  two-year  period  did not fairly
represent  goals for the overall  performance  of the Company in the current and
expected economic environment for 2008 and 2009.  Accordingly,  the Compensation
Committee amended the performance criteria for all performance shares awarded to
the Company's  executive  officers and other employees by indexing the specified
targeted  levels of the Company's  stock price (as measured on a moving  average
basis) by  reference  to the  decline  in the  NASDAQ  Composite  Index (as also
measured on a moving average  basis) on the specified  dates during the two-year
period  and by  requiring  that the  Company's  performance  exceed  by  varying
percentage amounts the relative performance of the NASDAQ Composite Index on the
specified dates during the two-year period.

     The vesting  schedule for the performance  share awards and all other terms
and conditions of the performance share awards remain unchanged.
