The Lead Arrangers intend to commence syndication efforts promptly, and, until the earlier to occur of (x) the date that is 60 days following the Closing Date and (y) a Successful Syndication (as defined in the Arranger Fee Letter) (such earlier date, the “Syndication Date”), you agree actively to assist (and, to the extent not in contravention of the Merger Agreement, to use your commercially reasonable efforts to cause the Target and its subsidiaries to actively assist) the Lead Arrangers in completing a syndication reasonably satisfactory to the Lead Arrangers and you.  Such assistance shall include (A) your using commercially reasonable efforts to ensure that the syndication efforts benefit from your and your affiliates’ existing banking relationships, (B) direct contact between appropriate members of your senior management and advisors and the proposed Lenders (and, to the extent not in contravention of the Merger Agreement, using your commercially reasonable efforts to ensure such contact between senior management of the Target and the proposed Lenders), in all such cases at times and locations to be mutually agreed upon, (C) your preparing and providing to the Lead Arrangers (and, to the extent not in contravention of the Merger Agreement, using commercially reasonable efforts to cause the Target to prepare and provide) all customary information with respect to you and your subsidiaries and the Target and its subsidiaries and the Transactions, including all customary financial information and Projections (as defined below), as any Lead Arranger may reasonably request in connection with the arrangement and syndication of the Credit Facilities and your assistance (and, to the extent not in contravention of the Merger Agreement, using your commercially reasonable efforts to cause the Target to assist) in the preparation of one or more confidential information memoranda or lender slides (each, a “Confidential Information Memorandum”) and other customary marketing materials to be used in connection with the syndication (all such information, memoranda and material, “Information Materials”), (D) prior to the launch of the syndication, using your commercially reasonable efforts to procure a public corporate credit rating and a public corporate family rating in respect of the Company from Standard & Poor’s Ratings Services (“S&P”) and Moody’s Investors Service, Inc. (“Moody’s”), respectively, and ratings for each of the Senior Secured Facilities and the Senior Notes from each of S&P and Moody’s, (E) your hosting, with the Lead Arrangers, of one or more meetings of prospective Lenders at times and locations to be mutually agreed (and, to the extent not in contravention of the Merger Agreement, using your commercially reasonable efforts to cause the senior management of the Target to be available for such meetings) and (F) your ensuring that, prior to the Syndication Date, there is no competing offering, placement, arrangement

3

or syndication of any debt securities (other than as contemplated in the Fee Letters) or bank financing or other credit facilities (other than the Credit Facilities or any Permitted Surviving Debt (as defined below)) or announcement thereof by or on behalf of you and your subsidiaries that could reasonably be expected to materially impair our syndication of the Credit Facilities and your using commercially reasonable efforts to ensure that there is no competing offering, placement, arrangement or syndication of any debt securities or bank financing or other credit facilities or announcement thereof by or on behalf of the Target and its subsidiaries (other than the Credit Facilities or any Permitted Surviving Debt), in all cases under this clause (F), if such offering, placement, arrangement or syndication could reasonably be expected to materially impair our syndication of the Credit Facilities.  For purposes of this Commitment Letter and the Credit Documentation, the term “Permitted Surviving Debt” shall mean (i) purchase money indebtedness, capital leases and equipment financings of the Target and its Subsidiaries that will remain outstanding following the Closing Date, (ii) intercompany indebtedness among the Target and its subsidiaries, (iii) other ordinary course working capital facilities of the Target and its subsidiaries that will be repaid in full and terminated on or prior to the Closing Date, (iv) any indebtedness specifically contemplated by the Merger Agreement to remain outstanding following the Closing Date and (v) other customary indebtedness that is permitted to be outstanding by the terms of the Credit Documentation or is otherwise reasonably agreed by you and the Commitment Parties to remain outstanding following the Closing Date.

The Lead Arrangers will manage, in consultation with you, all aspects of the syndication, including decisions as to the selection of institutions to be approached and when they will be approached, when commitments will be accepted, which institutions will participate, the allocation of the commitments among the Lenders and the amount and distribution of fees among the Lenders, in all cases, subject to the provisions hereof with respect to Disqualified Lenders.  You hereby acknowledge and agree that the Lead Arrangers will have no responsibility other than to arrange the syndication as set forth herein and in no event shall any Commitment Party be subject to any fiduciary or other implied duties in connection with the transactions contemplated hereby.

At the request of the Lead Arrangers, you agree to assist in the preparation of a version of each Confidential Information Memorandum or other Information Material (a “Public Version”) consisting exclusively of information with respect to you, your affiliates, the Target and its subsidiaries and the Acquisition that is either publicly available or not material with respect to you and your affiliates, the Target and its subsidiaries, any of your or their respective securities or the Acquisition for purposes of United States federal and state securities laws (such information, “Non-MNPI”).  Such Public Versions, together with any other information prepared by you or the Target or your or its affiliates or representatives and conspicuously marked “Public” (collectively, the “Public Information”), which at a minimum means that the word “Public” will appear prominently on the first page of any such information, may be distributed by us to prospective Lenders who have advised us that they wish to receive only Non-MNPI (“Public Side Lenders”).  You acknowledge and agree that, in addition to Public Information and unless you promptly notify us otherwise, (a) drafts and final definitive documentation with respect to the Credit Facilities, (b) marketing term sheets and administrative materials prepared by the Lead Arrangers for prospective Lenders (such as a lender meeting invitation, allocations and funding and closing memoranda), and (c) notifications of changes in the terms of the Credit Facilities may be distributed to Public Side Lenders. You acknowledge that any Commitment Party’s public-side employees and representatives who are publishing debt analysts may participate in any meetings held pursuant to clause (E) of the third preceding paragraph; provided that, such analysts shall not publish any information obtained from such meetings (i) until the syndication of the Credit Facilities has been completed upon the making of allocations by the Lead Arrangers and the Lead Arrangers freeing the Credit Facilities to trade or (ii) in violation of any confidentiality agreement between you and the relevant Commitment Party.

In connection with our distribution to prospective Lenders of any Confidential Information Memorandum and, upon our request, any other Information Materials, you will execute and deliver to us a customary authorization letter authorizing such distribution and, in the case of any Public Version thereof or other Public Information, representing that it only contains Non-MNPI. Each Confidential Information Memorandum will be accompanied by a disclaimer exculpating you and us with respect to any use thereof and of any related Information Materials by the recipients thereof.

For the avoidance of doubt, you will not be required to provide any information to the extent that the provision thereof would violate any law, rule or regulation, or any obligation of confidentiality binding on you or your affiliates; provided that, at the reasonable request of any Lead Arranger, you shall use commercially reasonable efforts to obtain the relevant consents under such obligations of confidentiality to allow for the provision of such information.

4.              Information

You hereby represent and warrant that (with respect to any information relating to the Target and its subsidiaries, to your knowledge) (a) all written information (including all Information Materials), other than the Projections, other forward-looking information, budgets, forecasts, estimates and information of a general economic or industry specific nature (the “Information”), that has been or will be made

telecommunications or other information transmission systems, including, without limitation, SyndTrak, Intralinks, the internet, email or similar electronic transmission systems, except to the extent any such damages are found by a final, non-appealable judgment of a court of competent jurisdiction to arise from the gross negligence, bad faith or willful misconduct of such indemnified person (or any of its Controlled Related Parties).  None of the indemnified persons or you, the Target or any of your or their respective affiliates or the respective directors, officers, employees, advisors,

MTS Systems Corporation (the “Company”) intends to acquire (the “Acquisition”) all of the outstanding equity interests of a company previously identified to us as “Nickel” (the “Target”) pursuant to the Agreement and Plan of Merger, dated as of the Signing Date (together with all exhibits, schedules and disclosure letters thereto, the “Merger Agreement”), among the Company, the Target, and certain other parties.  In connection therewith, it is intended that:

(a)           The Company will (i) obtain senior secured credit facilities (the “Senior Secured Facilities”) consisting of a $100.0 million revolving credit facility and a $390.0 million term loan B facility and (ii) obtain $250.0 million in gross cash proceeds from either (x) the issuance of senior unsecured notes in a public offering or a private placement under Rule 144A or other private placement (the “Senior Notes”) and/or (y) if the Company does not, or is unable to, issue the full amount of the Senior Notes at or prior to the time the Acquisition is consummated, a senior unsecured bridge facility (“Bridge Facility”, and, together with the Senior Secured Facilities, the “Credit Facilities”) in an amount equal to $250.0 million less the gross cash proceeds from the issuance of the Senior Notes and Securities (as defined in the Arranger Fee Letter) (and, if applicable, less any gross cash proceeds from the (x) issuance of equity securities of the Company for the purpose of financing the Acquisition or paying other Transaction Costs (as defined below) and (y) funding of loans under the Term Loan Facility on the Closing Date in excess of the commitments in respect of the Term Loan Facility).

(b)           All existing indebtedness for borrowed money under the Credit Agreement, dated as of September 24, 2014 (as previously amended, the “Existing Credit Agreement”), among the Company, the foreign subsidiary borrowers from time to time party thereto, the lenders from time to time party thereto and JPMorgan Chase Bank, N.A., as administrative agent, will be refinanced or repaid in full and arrangements for the concurrent release of all related liens shall be made (the “Refinancing”).

(c)           The proceeds of the Senior Secured Facilities, the Senior Notes and the Bridge Facility (to the extent obtained), shall be applied (i) to refinance certain existing indebtedness of the Target and its subsidiaries, (ii) to pay the purchase price in connection with the Acquisition, (iii) to pay the fees, costs and expenses incurred in connection with the Transactions and (iv) to consummate the Refinancing (the amounts set forth in clauses (i) through (iv) above, collectively, the “Transaction Costs”).

The transactions described above are collectively referred to herein as the “Transactions”.  For purposes of this Commitment Letter and the Fee Letters, “Closing Date” shall mean the date of the satisfaction (or waiver by the Commitment Parties) of the conditions set forth in Exhibit D and the initial funding of the relevant Credit Facilities.

Exhibit D

PROJECT NICKEL
Conditions

The availability and initial funding of the Credit Facilities shall be subject to the satisfaction (or waiver by the Commitment Parties) of solely the following conditions (subject to the Limited Conditionality Provision).  Capitalized terms used but not defined herein have the meanings set forth in the Commitment Letter to which this Exhibit D is attached and in Exhibits A, B and C thereto.

1.             Each party thereto shall have executed and delivered the Credit Documentation on terms consistent with the Commitment Letter, and the Administrative Agent shall have received:

a.              customary closing certificates, corporate and organizational documents, good standing certificates and customary legal opinions; and

b.              a certificate from the chief financial officer of the Company, in the form attached as Annex I to this Exhibit D, certifying that the Company and its subsidiaries, on a consolidated basis after giving effect to the Transactions and the other transactions contemplated hereby, are solvent.

2.             Substantially concurrently with the initial fundings contemplated by the Commitment Letter, (a) as a condition to the funding of the Senior Secured Facilities, the Company shall have received $250.0 million in aggregate gross cash proceeds from the issuance of the Senior Notes (and any Securities) and/or the borrowing of the Initial Bridge Loans under the Bridge Facility (and, if applicable, any gross cash proceeds from the issuance of equity in the Company used to finance the Acquisition and pay other Transaction Costs) and (b) as a condition to the funding of the Bridge Facility, the Company shall have received $390.0 million in gross proceeds from the borrowing of the Term Loans under the Senior Secured Facilities.

3.             On the Closing Date, after giving effect to the Transactions, neither the Company nor any of its subsidiaries (including, for the avoidance of doubt, the Target and its subsidiaries) shall have any indebtedness for borrowed money other than the Credit Facilities, Permitted Surviving Debt and certain other indebtedness to be mutually agreed upon.  The Administrative Agent shall have received reasonably satisfactory evidence of repayment of all indebtedness to be repaid on the Closing Date and the discharge (or the making of arrangements for discharge) of all liens securing any assets or property of the Company and its subsidiaries (including the Target and its Subsidiaries) other than liens permitted to remain outstanding under the Credit Documentation.

4.             The Acquisition shall, substantially concurrently with the initial funding of the Credit Facilities, be consummated pursuant to the Merger Agreement, and no provision thereof shall have been amended or waived, and no consent or request shall have been given under the Merger Agreement, in any way that is materially adverse to the Lenders in their capacities as such (it being understood and agreed that (a) amendments, waivers and other changes to the definition of “Material Adverse Effect” (or other term of similar import), and consents and requests given or made pursuant to such definition shall in each case be deemed to be materially adverse to the Lenders, and (b) any modification, amendment or express waiver or consents by you that results in (x) an increase to the purchase price shall be deemed to not be materially adverse to the Lenders so long as such increase is funded solely with a public issuance of common equity of the Company and (y) a decrease to the purchase price shall be deemed to not be materially adverse to the Lenders so long as such reduction is allocated first, to reduce the commitments under the Bridge Facility and second to reduce commitments under the Senior Secured Facilities (pro rata

D-1

as between the Revolving Credit Facility and the Term Loan Facility) without the prior written consent of the Commitment Parties (not to be unreasonably withheld, conditioned or delayed).

5.             The closing and effectiveness of, and initial funding under, the Credit Facilities shall have occurred on or before the Expiration Date.

6.             The Commitment Parties shall have received (a) audited consolidated balance sheets and related statements of income, stockholders’ equity and cash flows of each of the Company and its subsidiaries and the Target and its subsidiaries, for the three most recently completed fiscal years ended at least 90 days before the Closing Date and (b) unaudited consolidated balance sheets and related statements of income, stockholders’ equity and cash flows of each of the Company and its subsidiaries and the Target and its subsidiaries, for each subsequent fiscal quarter ended at least 60 days before the Closing Date; provided that filing of the required financial statements on form 10-K and/or form 10-Q by the Company or the Target will satisfy the foregoing requirements.

7.             As a condition to the availability of the Bridge Facility, (a) the Investment Bank (as defined in the Arranger Fee Letter referred to in the Commitment Letter) shall have received, not later than 15 business days prior to the Closing Date, a customary offering memorandum, including financial statements, pro forma financial statements, business and other financial data of the type and form that are customarily included in private placements pursuant to Rule 144A promulgated under the Securities Act (including information required by Regulation S-X and Regulation S-K under the Securities Act of 1933, which is understood not to include consolidating financial statements, “segment reporting”, separate subsidiary financial statements and other financial statements and data that would be required by Sections 3-09, 3-10 and 3-16 of Regulation S-X and Item 402 of Regulation S-K and information regarding executive compensation and related party disclosure related to SEC Release Nos. 33-8732A, 34-54302A and IC-27444A and other customary exceptions), to consummate the offering of the Senior Notes that would allow the auditors of each of the Company and the Target to issue customary comfort letters (including customary “negative assurance” comfort) upon completion of customary procedures in connection with the offering of the Senior Notes (and the Company shall have made all commercially reasonable efforts to provide the Investment Bank with drafts of such customary comfort letters), and (b) such Investment Bank shall have been afforded a period (the “Marketing Period”) of at least 15 consecutive business days upon receipt of the information described in clause (a) (such information, the “Required Information”), to seek to place the Senior Notes with qualified purchasers thereof, which period shall exclude certain market holiday related “blackout” periods as reasonably determined by the Lead Arrangers.  If the Company reasonably believes it has delivered the Required Information, the Company may deliver to the Lead Arrangers a written notice to that effect (stating when the Company reasonably believes it completed such delivery).  The notice delivered by the Company will be effective to start the Marketing Period as of the date of delivery of such notice (or such later date specified in such notice), unless on or prior to the second business day following delivery of the Company’s notice, the Lead Arrangers deliver written notice to the Company stating that they do not believe the Company has delivered the Required Information and specifying in reasonable detail the Required Information that has not been received (provided that delivery of such written notice from the Lead Arrangers to the Company will not prejudice the Company’s right to assert that the Required Information has, in fact, been delivered).

8.             The Commitment Parties shall have received a pro forma consolidated balance sheet and related pro forma consolidated statement of income of the Company and its subsidiaries as of and for the twelve-month period ending on the last day of the most recently completed four-fiscal quarter period ended at least 60 days prior to the Closing Date, prepared after giving effect to the Transactions (including the acquisition of the Target) as if the Transactions had occurred as of such date (in the case of such balance sheet) or at the beginning of such period (in the case of such statement of income).

D-2

9.             (a) Each of the Merger Agreement Representations shall be true and correct; and (b) each of the Specified Representations shall be true and correct in all material respects (and in all respects if qualified by material adverse effect or other materiality qualifier).

10.          The Administrative Agent shall have received, at least 2 business days prior to the Closing Date, all documentation and other information about the Company and the Guarantors as shall have been reasonably requested in writing by either Administrative Agent or by the Lead Arrangers at least 10 days prior to the Closing Date and required by U.S. regulatory authorities under applicable “know your customer” and anti-money laundering rules and regulations, including the PATRIOT Act.

11.          All fees and expenses due and payable to the Commitment Parties and the Lenders and required to be paid on or prior to the Closing Date shall have been paid or shall have been authorized to be deducted from the proceeds of the initial fundings under the Credit Facilities, so long as any such fees or expenses not expressly set forth in the Fee Letters have been invoiced not less than two (2) business day prior to the Closing Date (except as otherwise reasonably agreed by the Company).

12.          Subject to the Limited Conditionality Provision, all actions necessary to establish that the Administrative Agent will have a perfected first priority security interest (subject to liens permitted under the Credit Documentation) in the Collateral shall have been taken.

13.          The Lead Arrangers (a) shall have received one or more customary confidential information memoranda and other marketing material customarily used for the syndication of the Credit Facilities and (b) shall have been afforded a reasonable period of time to syndicate the Credit Facilities, which in no event shall be less than 15 consecutive business days from the date of delivery of the confidential information memorandum to the Lenders, which period shall exclude certain market holiday related “blackout” periods as reasonably determined by the Lead Arrangers.

14.          Except as set forth in the Schedules, and except for any transactions contemplated by the Merger Agreement and the other Covered Agreements, since the date of the Reference Balance Sheet there shall not have been any Material Adverse Effect.  For purposes hereof, “Material Adverse Effect” means any event, occurrence, fact, condition or change that, individually or in the aggregate, has had or would be reasonably expected to have a material adverse effect on:

a. the business, assets, Liabilities, results of operations or financial condition of the Target and its Subsidiaries taken as a whole; or

b. the ability of the Target to consummate the transactions contemplated by the Merger Agreement; provided, however, only with respect to clause (a) above, that “Material Adverse Effect” does not include any event, occurrence, fact, condition or change, directly or indirectly, to the extent arising out of or attributable to:

(1)                                 any change in general economic or political conditions;

(2)                                 any change in conditions generally affecting the industries in which the Target or any Subsidiary operates;

(3)                                 any change in financial, banking or securities markets in general, including any disruption thereof and any decline in the price of any security or any market index or any change in prevailing interest rates;

D-3

(4)                                 any act of war (whether or not declared), armed hostility or terrorism, or the escalation or worsening thereof, any natural or man-made disaster or acts of God (provided that, the exception in this clause (4) shall not apply to any of the foregoing that causes any material damage or destruction to or renders unusable any facility or asset of the Target or its Subsidiaries);

(5)                                 any action required or permitted by the Merger Agreement or any other Covered Agreement or any action taken (or omitted to be taken) with the written consent of or at the written request of the Company, including, in both cases, with respect to the Debt Financing;

(6)                                 any change in Applicable Law or accounting rules (including GAAP) or the enforcement, implementation or interpretation thereof;

(7)                                 the announcement, pendency or completion of the transactions contemplated by the Merger Agreement or any other Covered Agreement, including with respect to the Debt Financing, including losses or threatened losses of employees, customers, suppliers, distributors or others having relationships with the Target and/or its Subsidiaries, or any communication by the Company or any of its Affiliates regarding their plans or intentions with respect to the post-Closing conduct of the business or assets of the Target or its Subsidiaries (provided that, the exception in this clause (7) shall not obviate a breach of Section 3.4 of the Merger Agreement to the extent that the purpose thereof is to address the consequences resulting from the announcement, pendency or completion of the transactions contemplated by the Merger Agreement);

(8)                                 any act or omission of the Company or Merger Sub or their respective Affiliates or Representatives after the date of the Merger Agreement (other than any act or omission specifically contemplated thereunder); or

(9)                                 any failure of the Target and/or any of its Subsidiaries to meet any internal or published projections, forecasts or revenue or earnings predictions (but not the underlying cause thereof);

except, in the case of any of the foregoing clauses (1) through (3), and clause (6), to the extent such event, occurrence, fact, condition or change disproportionately and materially adversely affects (but only to the extent of such disproportionate material adverse effect) the Target and its Subsidiaries, taken as a whole, relative to other companies of similar size in the industries in which the Target and the Subsidiaries operate.

Capitalized terms used in this paragraph 14 but otherwise not defined herein shall have the meaning set forth in the Merger Agreement.
