termination of this Agreement, on the dates specified in Section 3.1, and an amount equal to the average annual bonus earned by the Employee as an employee of Avocent Corporation and its
affiliates and predecessors in the two (2) years immediately preceding the date of termination. Notwithstanding anything in this Section 4.1 to the contrary, the Employee may in the

on the dates specified in Section 3.1, and an amount equal to the average annual bonus earned by the Employee as an employee of Avocent Corporation and its affiliates and predecessors in the
two (2) years immediately preceding the date of termination. Notwithstanding anything in this Section 4.2 to the contrary, the Employee may in the Employee's sole discretion, by delivery
of a notice to the Employer within thirty (30) days following a Termination Other Than for Cause, elect to receive from the Employer a lump sum severance payment by bank cashier's check equal
to the present value of the flow of cash payments that would otherwise be paid to the Employee pursuant to this Section 4.2. Such present value shall be determined as of the date of delivery of
the notice of election by the Employee and shall be based on a discount rate equal to the interest rate on 90-day U.S. Treasury bills, as reported in The Wall
Street Journal (or similar publication), on the date of delivery of the election notice. If the Employee elects to receive a lump sum severance payment, Avocent Corporation
shall cause the Employer to make such payment to the Employee within ten (10) days following the date on which the Employee notifies the Employer of the Employee's election. The Employee shall
also be entitled to have the vesting of any awards granted to the Employee under any Apex or Avocent stock option plans fully accelerated.

thereafter, the Employee will not, without the Employer's prior written consent, directly or indirectly, alone or as a partner, joint venturer, officer, director, employee, consultant, agent,
independent contractor or stockholder of any company or business, engage in any business activity in the United States, Canada, or Europe which is substantially similar to or in direct competition
with any of the business activities of or services provided by the Employer at such time (a "Competing Business"). Notwithstanding the foregoing, (i) the ownership by the Employee of not more
than five percent (5%) of the shares of stock of any corporation having a class of equity securities actively traded on a national securities exchange or on The Nasdaq Stock Market shall not be
deemed, in and of itself, to violate the prohibitions of this Section 5, and (ii) the Employee's performance of services in any capacity for any consulting firm, public accounting firm,
or law firm that has as a client any company or business that is a Competing Business shall not violate the
prohibitions of this Section 5 so long as the Employee does not perform any services directly for such Competing Business. 

    MISCELLANEOUS.  

    PAYMENT
OBLIGATIONS.  If litigation after a Change in Control shall be brought to enforce or interpret any provision contained herein, the Employer and Avocent
Corporation, to

the extent permitted by applicable law and the Employer's and Avocent Corporation's Articles of Incorporation and Bylaws, each hereby indemnifies the Employee for the Employee's reasonable attorneys'
fees and disbursements incurred in such litigation. 

    GUARANTEE.  Avocent
Corporation hereby unconditional and irrevocable guarantees the payment obligations of the Employer under this Agreement, including, without
limitation, the Employer's obligations under Section 6.1 hereof. 

    WITHHOLDINGS.  All
compensation and benefits to the Employee hereunder shall be reduced by all federal, state, local, and other withholdings and similar taxes and
payments required by applicable law. 

    WAIVER.  The
waiver of the breach of any provision of this Agreement shall not operate or be construed as a waiver of any subsequent breach of the same or other
provision hereof. 

    ENTIRE
AGREEMENT; MODIFICATIONS.  Except as otherwise provided herein, this Agreement represents the entire understanding among the parties with respect to the subject
matter hereof, and this Agreement supersedes any and all prior understandings, agreements, plans and negotiations, whether written or oral with respect to the subject matter hereof including without

Employee and Apex, which such section shall be of no further force or effect (although the other sections of such Proprietary Information and Non-Competition Agreement shall remain in full
force and effect), and any understandings, agreements or obligations respecting any past or future compensation, bonuses, reimbursements or other payments to the Employee from the Employer or Avocent
Corporation. In

under any Apex or Avocent stock option plan (including, without limitation, Employee's September 18, 2000 stock option award from Avocent Corporation). All modifications to the Agreement must

this Agreement shall be binding upon and inure to the benefit of the surviving or resulting corporation or person. This Agreement shall be binding upon and inure to the benefit of the executors,
administrators, heirs, successors and assigns of the parties; provided, however, that except as herein expressly provided, this Agreement shall not be assignable either by the Employer (except to an
affiliate of the Employer (including Avocent Corporation) in which event the Employer shall remain liable if the affiliate fails to meet any obligations to make payments or provide benefits or
otherwise) or by the Employee. 

    COUNTERPARTS.  This
Agreement may be executed in one or more counterparts, all of which taken together shall constitute one and the same Agreement.

FOR SECTION 4999 EXCISE TAXES.  In the event that it shall be determined that any payment or other benefit paid by the Employer or Avocent Corporation
to or for the benefit of the Employee under this Agreement or otherwise, but determined without regard to any additional payments required under this Amendment (the "Payments") would be subject to the
excise tax imposed
by Section 4999 of the Internal Revenue Code (the "Excise Tax"), then the Employer and Avocent Corporation shall indemnify the Employee for such Excise Tax in accordance with the following: 

    The
Employee shall be entitled to receive an additional payment from the Employer and/or Avocent Corporation equal to (i) one hundred percent (100%) of any Excise Tax actually
paid or finally or payable by the Employee in connection with the Payments, plus (ii) an additional payment in such amount that after all taxes, interest and penalties incurred in connection
with all payments under this Section 2(a), the Employee retains an amount equal to one hundred percent (100%) of the Excise Tax. 

    All
determinations required to be made under this Section shall be made by the Avocent Corporation's primary independent public accounting firm, or any other nationally recognized
accounting firm reasonably acceptable to the Avocent Corporation and the Employee (the "Accounting Firm"). Avocent Corporation shall cause the Accounting Firm to provide detailed supporting
calculations of its determinations to the Employer and the Employee. All fees and expenses of the Accounting Firm shall be borne solely by the Employer. For purposes of making the calculations
required by this Section, the Accounting Firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the
application of Sections 280G and 4999 of the Internal Revenue Code, provided the Accounting Firm's determinations must be made with substantial authority (within the meaning of Section 6662 of
the Internal Revenue Code). The payments to which the Employee is entitled pursuant to this Section shall be paid by the Employer and/or Avocent Corporation to the Employee in cash and in full not
later than thirty (30) calendar days following the date the Employee becomes subject to the Excise Tax.

    4.  SEVERANCE
COMPENSATION.  

    4.1  SEVERANCE
COMPENSATION IN THE EVENT OF A TERMINATION UPON A CHANGE IN CONTROL.  In the event the Employee's employment is terminated in a
Termination Upon a Change in Control, the Employee shall be paid as severance compensation his Base Salary (at the rate payable at the time of such termination) for a period of twelve
(12) months from the date of termination of this Agreement, on the dates specified in Section 3.1, and an amount equal to the average annual bonus earned by the Employee as an employee
of Avocent Corporation and its affiliates and predecessors in the two (2) years immediately preceding the date of termination. Notwithstanding anything in this Section 4.1 to the
contrary, the Employee may in the Employee's sole discretion, by delivery of a notice to the Employer within thirty (30) days following a Termination Upon a Change in Control, elect to receive
from the Employer a lump sum severance payment by bank cashier's check equal to the present value of the flow of cash payments that would otherwise be paid to the Employee pursuant to this
Section 4.1. Such present value shall be determined as of the date of delivery of the notice of election by the Employee and shall be based on a discount rate equal to the interest rate of
90-day U.S. Treasury bills, as reported in The Wall Street Journal (or similar publication), on the date of delivery of the election notice.
If the Employee elects to receive a lump sum severance payment, Avocent Corporation shall cause the Employer to make such payment to the Employee within ten (10) days following the date on
which the Employee notifies the Employer of the Employee's election. The Employee shall also be entitled to have the vesting of any awards granted to the Employee under any Cybex or Avocent stock
option plans fully accelerated. The Employee shall be provided with medical plan benefits under any health plans of Avocent or Employer in which the Employee is a participant to the full extent of the
Employee's rights under such plans for a period of 12 months from the date of termination of this Agreement; provided, however, that the benefits under any such plans of Employer or Avocent in
which the Employee is a participant, including any such perquisites, shall cease upon employment by a new employer. 

    4.2  SEVERANCE
COMPENSATION IN THE EVENT OF A TERMINATION OTHER THAN FOR CAUSE.  In the event the Employee's employment is terminated in a Termination
Other Than for Cause, the Employee shall be paid as severance compensation his Base Salary (at the rate payable at the time of such termination) for a period of twelve (12) months from the date 

6

of such termination, on the dates specified in Section 3.1, and an amount equal to the average annual bonus earned by the Employee as an employee of Avocent Corporation and its affiliates and
predecessors in the two (2) years immediately preceding the date of termination. Notwithstanding anything in this Section 4.2 to the contrary, the Employee may in the Employee's sole
discretion, by delivery of a notice to the Employer within thirty (30) days following a Termination Other Than for Cause, elect to receive from the Employer a lump sum severance payment by bank
cashier's check equal to the present value of the flow of cash payments that would otherwise be paid to the Employee pursuant to this Section 4.2. Such present value shall be determined as of
the date of delivery of the notice of election by the Employee and shall be based on a discount rate equal to the interest rate on 90-day U.S. Treasury bills, as reported in  The Wall Street Journal (or
similar publication), on the date of delivery of the election notice. If the Employee elects to receive a lump sum severance
payment, Avocent Corporation shall cause the Employer to make such payment to the Employee within ten (10) days following the date on which the Employee notifies the Employer of the Employee's
election. The Employee shall also be entitled to have the vesting of any awards granted to the Employee under any Cybex or Avocent stock option plans fully accelerated.

compensation. 

    5.  NON-COMPETITION
OBLIGATIONS.  Unless waived or reduced by the Employer or Avocent, during the term of this Agreement and for a period of
12 months thereafter, the Employee will not, without the Employer's prior written consent, directly or indirectly, alone or as a partner, joint venturer, officer, director, employee,
consultant, agent, independent contractor or stockholder of any company or business, engage in any business activity in the United States, Canada, or Europe which is substantially similar to or in
direct competition with any of the business activities of or services provided by the Employer at such time. Notwithstanding the foregoing, the ownership by the Employee of not more than five percent
(5%) of the shares of stock of any corporation having a class of equity securities actively traded on a national securities exchange or on The Nasdaq Stock Market shall not be deemed, in and of
itself, to violate the prohibitions of this Section 5. 

    6.  MISCELLANEOUS.  

    6.1  PAYMENT
OBLIGATIONS.  If litigation after a Change in Control shall be brought to enforce or interpret any provision contained herein, the Employer
and Avocent Corporation, to the extent permitted by applicable law and the Employer's and Avocent Corporation's Articles of Incorporation and Bylaws, each hereby indemnifies the Employee for the
Employee's reasonable attorneys' fees and disbursements incurred in such litigation.

Corporation hereby unconditional and irrevocable guarantees the payment obligations of the Employer under this Agreement,

respect to the subject 

7

matter hereof, and this Agreement supersedes any and all prior understandings, agreements, plans and negotiations, whether written or oral with respect to the subject matter hereof including without

stock option awards granted to Employee under any Cybex or Avocent stock option plan (including, without limitation, Employee's September 18, 2000 stock option award from Avocent Corporation).
All modifications to the Agreement must be in writing and signed by the party against whom enforcement of such modification is sought.

otherwise, the provisions of this Agreement shall be binding upon and inure to the benefit of the surviving or resulting corporation or person. This Agreement shall be binding upon and inure to the
benefit of the executors, administrators, heirs, successors and assigns of the parties; provided, however, that except as herein expressly provided, this Agreement shall not be assignable either by
the Employer (except to an affiliate of the Employer (including Avocent Corporation) in which event the Employer shall remain liable if the affiliate fails to meet any obligations to make payments or
provide benefits or otherwise) or by the Employee. 

    6.12  COUNTERPARTS.  This
Agreement may be executed in one or more counterparts, all of which taken together shall constitute one and the same Agreement. 

    6.13  INDEMNIFICATION.  In
addition to any rights to indemnification to which the Employee is entitled to under the Employer's Articles of Incorporation
and Bylaws, the Employer and Avocent Corporation shall indemnify the Employee at all times during and after the term of this Agreement to the maximum extent permitted under the corporation laws of the
State of Delaware and any other applicable state law, and shall pay the Employee's expenses in defending any civil or criminal action, suit, or proceeding in advance of the final disposition of such
action, suit, or proceeding, to the maximum extent permitted under such applicable state laws. 

    6.14  INDEMNIFICATION
FOR SECTION 4999 EXCISE TAXES.  In the event that it shall be determined that any payment or other benefit paid by the Employer or
Avocent Corporation to or for the benefit of the Employee under this Agreement or otherwise, but determined without regard to any additional payments required under this Amendment (the "Payments")
would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code (the "Excise Tax"), then the Employer and Avocent Corporation shall indemnify the Employee for such
Excise Tax in accordance with the following: 

    (a) The
Employee shall be entitled to receive an additional payment from the Employer and/or Avocent Corporation equal to (i) one hundred percent (100%) of any
Excise Tax actually paid or finally or
payable by the Employee in connection with the Payments, plus (ii) an additional payment in such amount that after all taxes, interest and penalties incurred in connection with all payments
under this Section 2(a), the Employee retains an amount equal to one hundred percent (100%) of the Excise Tax. 

    (b) All
determinations required to be made under this Section shall be made by the Avocent Corporation's primary independent public accounting firm, or any other
nationally recognized accounting firm reasonably acceptable to the Avocent Corporation and the Employee (the "Accounting Firm"). Avocent Corporation shall cause the Accounting Firm to provide detailed
supporting calculations of its determinations to the Employer and the Employee. All fees and expenses of the Accounting Firm shall be borne solely by the Employer. For purposes of making the
calculations required by this Section, the Accounting Firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations
concerning the application of Sections 280G and 4999 of the Internal Revenue Code, provided the Accounting Firm's determinations must be made with substantial authority (within the meaning of
Section 6662 of the Internal 

9

Revenue Code). The payments to which the Employee is entitled pursuant to this Section shall be paid by the Employer and/or Avocent Corporation to the Employee in cash and in full not later than
thirty (30) calendar days following the date the Employee becomes subject to the Excise Tax. 

    IN
WITNESS WHEREOF, the parties hereto have executed this Agreement as of the day and year first above written.
