 1 









 “provided, however, that notwithstanding the foregoing,

 2.
Waivers. Subject to the terms and conditions set forth herein, and in reliance upon the representations and warranties of the Borrower made herein, the Agent and the Lenders signatory hereto hereby permanently waive any Default or
Event of Default having occurred or to occur directly as a result of (A) the breach of Section 8.05 of the Credit Agreement as a result of CSI’s entering into an agreement to sell the Erdman Company for nominal consideration,

The waivers set forth in this Section 2 are limited to the extent specifically set forth above and shall in no way serve to
waive any other terms, covenants or provisions of the Credit Agreement or any other Loan Document, or any obligations of the Borrower or CSI, other than as expressly set forth above. The Borrower and CSI hereby consent, acknowledge and agree to the
waivers set forth herein and hereby confirm and ratify in all respects the Credit Agreement as amended hereby and the enforceability of such Credit Agreement against the Borrower and CSI in accordance with its terms.

(a) The representations and warranties made by it in Article VI of the Credit Agreement are true and correct in all
material respects on and as of the date hereof after giving effect to this Amendment, except to the extent that such representations and warranties expressly relate to an earlier date, in which case such representations and warranties are true and
correct as of such earlier date; 
 (b) This Amendment has been duly authorized, executed and delivered by the
Borrower and CSI and constitutes a legal, valid and binding obligation of each such party, except as may be limited by general principles of equity or by the effect of any applicable bankruptcy, insolvency, reorganization, moratorium or similar law
affecting creditors’ rights generally; and 
 (c) Upon the effectiveness hereof, no Default or Event of
Default exists.

(collectively, the “Relevant Documents”), sets forth the entire understanding and agreement of the parties hereto in relation to the subject matter hereof and supersedes any prior negotiations and agreements among the parties
relating to such subject matter. No promise, condition, representation or warranty, express or implied, not set forth in the Relevant Documents shall bind any party hereto, and no such party has relied on any such promise, condition, representation
or warranty. Each of the parties hereto acknowledges that, except as otherwise expressly stated in the Relevant Documents, no representations, warranties or commitments, express or implied, have been made by any party to the other. None of the terms
or conditions of this Amendment may be changed, modified, waived or canceled orally or otherwise, except in writing and in accordance with Section 11.01 of the Credit Agreement.

and construed in accordance with, the laws of the State of New York. 
 9. Enforceability. Should any one or more
of the provisions of this Amendment be determined to be illegal or unenforceable as to one or more of the parties hereto, all other provisions nevertheless shall remain effective and binding on the parties hereto. 

10. Successors and Assigns. This Amendment shall be binding upon and inure to the benefit of the Borrower, CSI, the Agent
and each Lender and their respective successors and assignees to the extent such assignees are permitted assignees as provided in Section 11.06 of the Credit Agreement. 

11. Expenses. Without limiting the provisions of Section 11.04 of the Credit Agreement, the Borrower agrees to
pay all reasonable out of pocket costs and expenses (including without limitation reasonable legal fees and expenses) incurred before or after the date hereof by the Agent and its Affiliates in connection with the preparation, negotiation,
execution, delivery and administration of this Amendment. 
 12. Consent of the Guarantors. Each Guarantor hereby
consents, acknowledges and agrees to the amendment, waivers and release set forth herein and hereby confirms and ratifies in all respects the Loan Documents to which such Person is a party (including without limitation the continuation of such
