THIS
CHANGE IN CONTROL AGREEMENT is made and entered into by and between MTS Systems
Corporation, a Minnesota corporation with its principal offices at 14000
Technology Drive, Eden Prairie, MN 55344 (the Company) and Susan
E. Knight (the Executive),
residing at Eden Prairie (business location), and shall be effective as of this
31st day of December, 2008

WHEREAS,
the Company considers the establishment and maintenance of a sound and vital
management to be essential to protecting and enhancing the best interests of
the Company and its shareholders; and

WHEREAS,
the Executive has made and is expected to continue to make, due to the
Executives intimate knowledge of the business and affairs of the Company, its
policies, methods, personnel, and problems, a significant contribution to the
profitability, growth, and financial strength of the Company; and

WHEREAS,
the Company, as a publicly held corporation, recognizes that the possibility of
a Change in Control may exist, and that such possibility and the uncertainty
and questions which it may raise among management may result in the departure
or distraction of the Executive in the performance of the Executives duties,
to the detriment of the Company and its shareholders; and

WHEREAS,
it is in the best interests of the Company and its stockholders to reinforce
and encourage the continued attention and dedication of management personnel,
including the Executive, to their assigned duties without distraction and to
ensure the continued availability to the Company of the Executive in the event
of a Change in Control; and

WHEREAS,
the Company and the Executive previously signed a Change in Control Agreement
and now desire to amend and restate that Agreement in its entirety to exempt it
from the requirements applicable to nonqualified deferred compensation plans
pursuant to Section 409A of the Code and regulations promulgated thereunder,
and this Agreement shall be construed and administered in a manner that is
consistent with and gives effect to such intention.

THEREFORE,
in consideration of the foregoing and other respective covenants and agreements
of the parties herein contained, the parties hereto agree as follows:

1.
          Term of
Agreement. This Agreement shall be effective from and after the date hereof
and shall continue in effect through December 31, 2009, and shall automatically
be extended for successive one-year periods thereafter unless the Board of
Directors of the Company (the Board) shall have approved, and the Executive
is notified in writing, prior to January 1, 2010 and each January 1 thereafter,
that the term of this Agreement shall not be extended or further extended;
provided, however, that if a Change in Control shall have occurred during the
original or any extended term of this Agreement, this Agreement shall continue
in effect for a period of 24 months from the date of the occurrence of a Change
in Control or, if an event triggering the Companys severance payment
obligations to the Executive under Section 4(d) has occurred during such 24-month
period, this Agreement shall continue in effect until the benefits payable to
the Executive hereunder have been paid in full. In the event that more than one
Change in Control shall occur during the original or any extended term of this
Agreement, the 24-month period shall follow the last Change in Control. This
Agreement shall neither impose nor confer any further rights or obligations on
the Company or the Executive on the day after the end of the term of this
Agreement. Expiration of the term of this Agreement of itself and without
subsequent action by the Company or the Executive shall not end the employment
relationship between the Company and the Executive.

Change in Control Agreement

2.          Change
in Control. No benefits shall be payable hereunder unless there shall have been
a Change in Control. For purposes of this Agreement, a Change in Control of
the Company shall mean a change in control which would be required to be
reported in response to Item 6(e) on Schedule 14A of Regulation 14A promulgated
under the Securities Exchange Act of 1934, as amended (the Exchange Act),
whether or not the Company is then subject to such reporting requirement,
including, without limitation, if:

 other reorganization of the Company with any corporation or entity, other
 than an entity owned at least 80% by the Company, unless immediately after
 such transaction, the shareholders of the Company immediately prior to such
 transaction beneficially own, directly or indirectly 51% or more of the
 combined voting power of resulting entitys outstanding voting securities as
 well as 51% or more of the Total Market Value of the resulting entity, or in
 the case of a division, 51% or more of the combined voting power of the
 outstanding voting securities of each entity resulting from the division as
 well as 51% or more of the Total Market Value of each such entity, in each
 case in substantially the same proportion as such shareholders owned shares
 of the Company prior to such transaction; (ii) the shareholders of the
 Company approve an agreement for the sale or disposition (in one transaction
 or a series of transactions) of assets of the Company, the total consideration
 of which is greater than 51% of the Total Market Value of the Company, or
 (iii) the Company adopts a plan of complete liquidation or winding-up of the
 Company. Total Market Value shall mean the aggregate market value of the
 Companys or the resulting entitys outstanding common stock (on a fully
 diluted basis) plus the aggregate market value of the Companys or the
 resulting entitys other outstanding equity securities as measured by the
 exchange rate of the transaction or by such other method as the Board
 determines where there is not a readily ascertainable exchange rate.

 unless committed, or omitted by the Executive in bad faith and without
 reasonable belief that the Executives act or failure to act was in the best
 interest of the Company and the Executive shall have either failed to
 correct, or failed to take all reasonable steps to correct, such act or
 failure to act within sixty (60) days from the Executives receipt of written
 notice from the Company demanding that the Executive take such action. The
 Executive shall not be terminated for Cause unless and until the Company
 shall have delivered to the Executive a copy of a resolution duly adopted by
 the affirmative vote of not less than three-quarters of the entire membership
 of the Board at a meeting of the Board called and held for such purpose
 (after reasonable notice to the Executive and an opportunity for the
 Executive, together with the Executives counsel, to be heard before the
 Board), finding that, in the good faith opinion of the Board, the Executives
 conduct was Cause and specifying the particulars thereof in detail.

 of Termination. If, within 10 days after any Notice of Termination is
 given, the party receiving such Notice of Termination notifies the other
 party that a dispute exists concerning the termination, the Date of
 Termination shall be the date on which the dispute is finally determined,
 either by mutual written agreement of the parties, or by a final judgment,
 order or decree of a court of competent jurisdiction (which is not appealable
 or the time for appeal therefrom having expired and no appeal having been
 perfected); provided, that the Date of Termination shall be extended by a
 notice of dispute only if such notice is given in good faith and the party
 giving such notice pursues the resolution of such dispute with reasonable
 diligence. Notwithstanding the pendency of any such dispute, the Company
 shall continue to pay the Executive full compensation in effect when the
 notice giving rise to the dispute was given (including, but not limited to,
 base salary) and continue the Executive as a participant in all compensation,
 benefit and insurance plans in which the Executive was participating when the
 notice giving rise to the dispute was given, until the dispute is finally
 resolved in accordance with this subsection. Amounts paid under this
 subsection are in addition to all other amounts due under this Agreement and
 shall not be offset against or reduce any other amounts under this Agreement.

| | (h)          Separation
 from Service. Separation from Service means the Executives termination
 of employment (as defined in this subsection 3(h)) from the Company and its
 Affiliates. A Executive incurs a termination of employment that constitutes a
 Separation from Service if the Executive and the Compensation Committee of
 the Board of Directors of the Company reasonably anticipate either than the
 Executive will not perform any additional services after a certain date for
 the Company and any Affiliate (the Company Group), or that the Executives
 level of bona fide services for the Company Group will permanently decrease
 to no more than 20% of the average level of bona fide services performed over
 the immediately preceding 36-month period. The Executive does not incur a
 Separation from Service if on military leave, sick leave, or other bona fide
 leave of absence if such leave does not exceed a period of 6 months, or if
 longer, the period for which a statute or contract provides the Executive with
 the right to reemployment with the Company Group, provided that there is a
 reasonable expectation that the Executive will return to perform further
 services. If an Executives leave exceeds 6 months but the Executive is not
 entitled to reemployment under a statute or contract, the Executive incurs a
 Separation from Service on the next day following the expiration of 6 months.
 Where a leave of absence is due to a Disability, the 6 month leave period
 described above shall be 12 months unless the leave is earlier terminated.
 The service of the Executive as a director of the board of any entity in the
 Company Group will not be considered in determining whether the Executive has
 incurred a Separation from Service as an employee of the Company Group. The
 Compensation Committee will determine whether a Executive has incurred a
 Separation from Service based on the facts and circumstances and in
 accordance with Treas. Reg. §1.409A-1(h)(1)(ii). For purposes of this
 subsection 3(h), Affiliate means an entity that would be considered with
 the Company a single employer under Sections 414(b) and (c) and 1563(a) of
 the Code, except that 50% shall be substituted for the 80% each place it
 appears in Sections 414(b) and (c) and 1563(a) of the Code.

 lieu of any further salary payments for periods subsequent to the Date of
 Termination, the Company shall pay a severance payment (the Severance
 Payment) equal to two times the Executives Annual Compensation as defined
 below. For purposes of this Section 4, Annual Compensation shall mean the
 Executives annual salary (regardless of whether all or any portion of such
 salary has been contributed to a deferred compensation plan), the average
 annual Management Variable Compensation (MVC) earned by the Executive
 during the three (3) fiscal years immediately preceding the Date of
 Termination or, if less, the actual number of fiscal years the Executive has
 participated in the MVC plan, and any other type or form of compensation paid
 to the Executive by the Company (or any corporation (an Affiliate)
 affiliated with the Company within the meaning of Section 1504 of the
 Internal Revenue Code of 1986 as it may be amended from time to time (the
 Code)) and included in the Executives gross income for federal tax
 purposes during the 12-month period ending immediately prior to the Date of
 Termination, but excluding: a) any amount actually paid to the Executive as a
 cash payment of the target bonus (regardless of whether all or any portion of
 such Company bonus was contributed to a deferred compensation plan); b)
 compensation income recognized as a result of the exercise of stock options
 or sale of the stock so acquired; and c) any payments actually or
 constructively received from a plan or arrangement of deferred compensation
 between Company and the Executive. All of the items included in Annual
 Compensation shall be those in effect on the Date of Termination and shall be
 calculated without giving effect to any reduction in such compensation that
 would constitute a breach of this Agreement. The Severance Payment shall be
 made in a single lump sum within 30 days after the Date of Termination;

 Period, the Executive shall be eligible for continued health coverage as
 required by Code Section 4980B or other applicable law (COBRA Coverage), as
 if the Executives employment with the Company had terminated as of the end
 of the Benefit Continuation Period, and the Company shall take such actions
 as are necessary to cause such COBRA Coverage not to be offset by the
 provision of benefits under this paragraph (iii) and to cause the period of
 COBRA Coverage to commence at the end of the Benefit Continuation Period. The
 cost of providing such benefits shall be in addition to (and shall not
 reduce) the Severance Payment. Benefits otherwise receivable by the Executive
 pursuant to this paragraph (iii) shall be reduced to the extent comparable
 benefits are actually received by the Executive during the Benefit
 Continuation Period, and any such benefits actually received by Executive
 shall be reported to the Company; and

 Company will indemnify the Executive (and the Executives legal
 representative or other successors) to the fullest extent permitted
 (including payment of expenses in advance of final disposition of the
 proceeding) by the laws of the State of Minnesota, as in effect at the time
 of the subject act or omission, or the Articles of Incorporation and By-Laws
 of the Company as in effect at such time or on the date of this Agreement,
 whichever affords or afforded greater protection to the Executive; and the
 Executive shall be entitled to the protection of any insurance policies the
 Company may elect to maintain generally for the benefit of its directors and
 officers, against all costs, charges and expenses whatsoever incurred or
 sustained by the Executive or the Executives legal representatives in
 connection with any action, suit or proceeding to which the Executive (or the
 Executives legal representative or other successors) may be made a party by
 reason of the Executives being or having been a director, officer or
 employee of the Company or any of its subsidiaries or his or her serving or
 having served any other enterprise as a director, officer or employee at the
 request of the Company, provided that the Company shall cause to be
 maintained in effect for not less than six years from the date of a Change in
 Control (to the extent available) policies of directors and officers
 liability insurance of at least the same coverage as those maintained by the
 Company on the date of this Agreement and containing terms and conditions
 which are no less advantageous than such policies.

 Except as provided in subsection (c) below, the Executive agrees that, as a
 condition of receiving benefits under this Agreement, the Executive will not
 render services directly or indirectly to any competing organization,
 wherever located, for a period of one year following the Date of Termination,
 in connection with the design, implementation, development, manufacture,
 marketing, sale, merchandising, leasing, servicing or promotion of any
 Conflicting Product which as used herein means any product, process, system
 or service of any person, firm, corporation, organization other than the
 Company, in existence or under development, which is the same as or similar
 to or competes with, or has a usage allied to, a product, process, system, or
 service produced, developed, or used by the Company. The Executive agrees
 that violation of this covenant not to compete with the Company shall result
 in immediate cessation of all benefits hereunder, other than insurance

Change in Control Agreement

6.          Limits
on Payments and Benefits. In the event that the vesting, acceleration and
payment of any equity awards or other compensation or benefits, together with
all other payments and the value of any benefit received or to be received by
the Executive would result in all or a portion of such payment being subject to
excise tax under Section 4999 of the Code, then the amounts due under Section 4
that the Company shall pay to the Executive shall be either (A) the full
payment or (B) such lesser amount determined by the Company in accordance with
this Section 6 that would result in no portion of the payment being subject to
excise tax under Section 4999 of the Code (the Excise Tax), whichever of the
foregoing amounts, taking into account the applicable Federal, state, and local
employment taxes, income taxes, and the Excise Tax, results in the receipt by
the Executive, on an after-tax basis, of the greatest amount of the payment
notwithstanding that all or some portion of the payment may be taxable under Section
4999 of the Code. In the event the amounts due under Section 4 are reduced, the
amounts shall be reduced in the following order of priority: first, with
respect to any amount that does not constitute the deferral of compensation
under Section 409A of the Code and regulations promulgated thereunder,
disregard the acceleration in the time of payment and then disregard the
acceleration of vesting as a result of a Change in Control and second, with
respect to any amount that constitutes the deferral of compensation under
Section 409A of the Code and regulations promulgated thereunder, disregard the
acceleration in the time of payment and then disregard the acceleration of
vesting as a result of a Change in Control first with respect to Company funded
amounts and then the Executives deferrals, in each case only to the extent
necessary to satisfy (B) above. All determinations required to be made under
this Section 14 shall be made by a nationally recognized accounting firm that
is the Companys outside auditor immediately prior to the event triggering the
payments that are subject to the Excise Tax (the Accounting Firm). The
Company shall cause the Accounting Firm to provide detailed supporting
calculations of its determinations to the Company and Executive. Notice must be
given to the Accounting Firm within fifteen (15) business days after an event
entitling Executive to an amount due under this Agreement. All fees and
expenses of the Accounting Firm shall be borne solely by the Company. The
Accounting Firms determinations must be made with substantial authority
(within the meaning of Section 6662 of the Code). For the purposes of all
calculations under Section 280G of the Code and the application of this Section
6, all determination as to present value shall use 120 percent of the
applicable Federal rate (determined under Section 1274(d) of the Code)
compounded based on the nature of the payment, as in effect on the date of this
Agreement, but if not otherwise specified, the Company and Executive agree to
compound such rate on a semiannual basis. The determination by the Accounting
Firm shall be final and binding on the Company and the Executive.

7.          Funding
of Payments. In order to assure the performance of the Company or its
successor of its obligations under this Agreement, the Company may deposit in a
so-called rabbi trust an amount equal to the maximum payment that will be due
the Executive under the terms hereof; provided, however, that the Company shall
deposit in trust the amount equal to the maximum payment due Executive
immediately upon an Unfriendly Change in Control. Under such written trust
instrument, the trustee shall be instructed to pay to the Executive (or the
Executives legal representative, as the case may be) the amount to which the
Executive shall be entitled under the terms hereof, and the balance, if any, of
the trust not so paid or reserved for payment shall be repaid to the Company.
If the Company deposits funds in trust, payment shall be made no later than the
occurrence of the Change in Control. The written instrument governing the trust
shall be irrevocable from and after such Change in Control and shall contain
such provisions protective of the Executive as are contained in similar trust
agreements approved by the Internal Revenue Service in published private letter
rulings (provided that the assets of the trust shall be reachable by creditors
of the Company as required by such rulings). The trustee shall be a national
bank selected by the Company with the consent of the Executive, with trust
powers and whose principal officers are located in the Minneapolis/St. Paul
metropolitan area. The trustee shall invest the assets of the trust in any
readily marketable securities of U.S. corporations (other than the Company, its
successor, or any affiliate of the Company or its successor). If and to the
extent there are not amounts in trust sufficient to pay Executive under this
Agreement, the Company shall remain liable for any and all payments due to
Executive.

Change in Control Agreement

8.          Successors;
Binding Agreement.

(a)          The
Company will require any successor (whether direct or indirect, by purchase,
merger, consolidation or otherwise) to 51% or more of the business and/or
assets of the Company to expressly assume and agree to perform this Agreement
in the same manner and to the same extent that the Company would be required to
perform it if no such succession had taken place. Failure of the Company to
obtain such assumption and agreement prior to the effectiveness of any such
succession shall be a breach of this Agreement and shall entitle the Executive
to the compensation and benefits from the Company in the same amount and on the
same terms as the Executive would be entitled hereunder if the Executive
terminated his or her employment for Good Reason following a Change in Control,
except that for purposes of implementing the foregoing, the date on which any
such succession becomes effective shall be deemed the Date of Termination.

(b)          This
Agreement shall inure to the benefit of and be enforceable by the Executives
personal or legal representatives, successors, heirs, and designated
beneficiaries. If the Executive should die while any amount would still be
payable to the Executive hereunder if the Executive had continued to live, all
such amounts, unless otherwise provided herein, shall be paid in accordance
with the terms of this Agreement to the Executives designated beneficiaries,
or, if there is no such designated beneficiary, to the Executives estate.

9.          Notice.
For the purpose of this Agreement, notices and all other communications
provided for in the Agreement shall be in writing and shall be deemed to have
been duly given when delivered or mailed by United States registered or
certified mail, return receipt requested, postage prepaid, addressed to the
last known residence address of the Executive or in the case of the Company, to
its principal office to the attention of each of the then directors of the
Company with a copy to its Secretary, or to such other address as either party
may have furnished to the other in writing in accordance herewith, except that
notice of change of address shall be effective only upon receipt.

10.          Non-application
of Section 409A of the Code. It is the intent of the Company and the
Executive that this Agreement satisfy those requirements of Section 409A of the
Code to constitute first a short term deferral and then a separation pay
plan to exempt the payments hereunder from the definition of a nonqualified
deferred compensation plan under Section 409A of the Code, and the Agreement
shall be so administered and interpreted in manner consistent with, and that
gives effect to, such intention. The Company shall have the authority, without
the consent of the Executive to amend such provision to maintain to maximum
extent practicable the intent that this Agreement remains exempt from the
requirements applicable to a nonqualified deferred compensation plan under
Section 409A of the Code and regulations and other guidance promulgated
thereunder.

11.          Miscellaneous.
No provision of this Agreement may be modified, waived or discharged unless
such waiver, modification or discharge is agreed to in writing and signed by
the parties. No waiver by either party hereto at any time of any breach by the
other party to this Agreement of, or compliance with, any condition or
provision of this Agreement to be performed by such other-party shall be deemed
a waiver of similar or dissimilar provisions or conditions at the same or at
any prior or similar time. No agreements or representations, oral or otherwise,
express or implied, with respect to the subject matter hereof have been made by
either party which are not expressly set forth in this Agreement. The validity,
interpretation, construction and performance of this Agreement shall be
governed by the laws of the State of Minnesota.

affect the validity or enforceability of any other provision of this Agreement,
which shall remain in full force and effect.

IN
WITNESS WHEREOF, the undersigned officer, on behalf of MTS Systems Corporation,

written.
