pursuant to Section 6.2(b) is inaccurate (at a time when this Agreement is in effect and unpaid Obligations under this Agreement are outstanding (other than indemnities and other contingent obligations not yet due and payable)), and such
inaccuracy, if corrected, would have led to the application of a different Applicable Margin for any fiscal period, then the Applicable Margin for such fiscal period shall be determined by reference to the applicable Level in the above table for
such fiscal period which would have applied if a correct financial statement or certificate had been delivered, and the Borrower shall promptly pay to the Agent any additional accrued interest owing as a result of such increased Applicable Margin
for such fiscal period or the Agent shall promptly issue the Borrower a credit against the next succeeding interest payment due in the amount of the additional interest paid in excess of the interest which would have been due if the lower Applicable
Margin had been in effect for such Test Period.

without limiting the foregoing, each of the Borrower, Holdings and Manufacturing hereby confirms that the existing security interests granted by such Obligor in favor of the Secured Parties pursuant to the Loan Documents in the Collateral described
therein shall continue to secure the Obligations as and to the extent provided in the Loan Documents. 
 SECTION 8. Release. Each
Obligor hereby acknowledges and agrees that: (a) neither it nor any of its Subsidiaries has any claim or cause of action against the Agent, the Collateral Agent or any Lender (or any of the directors, officers, employees, agents, attorneys or

Affiliates. Notwithstanding the foregoing, the Agent, the Collateral Agent and the Lenders wish (and the Obligors agree) to eliminate any possibility that any past conditions, acts, omissions, events or circumstances would impair or otherwise
adversely affect any of their rights, interests, security and/or remedies. Accordingly, for and in consideration of the agreements contained in this Amendment and other good and valuable consideration, each Obligor (for itself and its Subsidiaries
and Affiliates and the successors, assigns, heirs and representatives of each of the foregoing) (collectively, the “Releasors”) does hereby fully, finally, unconditionally and irrevocably release, waive and forever discharge the
Agent, the Collateral Agent and the Lenders, together with their respective Affiliates and Related Funds, and each of the directors, officers, employees, agents, attorneys and consultants of each of the foregoing (collectively, the “Released
Parties”), from any and all debts, claims, allegations, obligations, damages, costs, attorneys’ fees, suits, demands, liabilities, actions, proceedings and causes of action, in each case, whether known or unknown, contingent or fixed,
direct or indirect, and of whatever nature or description, and whether in law or in equity, under contract, tort, statute or otherwise, which any Releasor has heretofore had or now or hereafter can, shall or may have against any Released Party by
reason of any act, omission or thing whatsoever done or omitted to be done, in each case, on or prior to the Second Amendment Effective Date directly arising out of, connected with or related to this Amendment, the Credit Agreement or any other Loan
Document, or any act, event or transaction related or attendant thereto, or the agreements of the Agent, the Collateral Agent or any Lender contained therein, or the possession, use, operation or control of any of the assets of any Obligor, or the
making of any Loans or other advances, or the management of such Loans or other advances or the Collateral. Each Obligor represents and warrants that it has no knowledge of any claim by any Releasor against any Released Party or of any facts or acts
or omissions of any Released Party which on the date hereof would be the basis of a claim by any Releasor against any Released Party which would not be released hereby. 

SECTION 9. No Reliance, Etc. For the avoidance of doubt, and without limitation of any other provisions of the Credit Agreement or the
other Loan Documents, Barclays Bank PLC, in its capacity as Agent and Collateral Agent, shall be entitled to the benefits of Sections 13.3, 13.4 and 14.18 of the Credit Agreement as if such provisions were set forth in full herein mutatis mutandis.

Collateral Agent or any Lender relative to the subject matter hereof not expressly set forth or referred to herein. Except as expressly set forth herein, this Amendment shall not by implication or otherwise limit, impair, constitute a waiver of, or
otherwise affect the rights and remedies of any party under, the Credit Agreement, nor alter, modify, amend or in any way affect any of the terms, conditions, obligations, covenants or agreements contained in the Credit Agreement, all of which are
ratified and affirmed in all respects and shall continue in full force and effect. It is understood and agreed that each reference in each Loan Document to the Credit Agreement, whether direct or indirect, shall hereafter be deemed to be a reference
to the Credit Agreement as modified hereby.

 SECTION 13. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES
THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF OR RELATED TO THIS AMENDMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF
THE PARTIES AGAINST ANY OTHER PARTY OR ANY AGENT-RELATED PERSON, PARTICIPANT OR ASSIGNEE, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE. EACH OF THE PARTIES HERETO AGREES THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY

hereunder shall not in any way affect or impair the legality or enforceability of the remaining provisions of this Amendment, the Credit Agreement, or any instrument or agreement required hereunder. 

SECTION 15. Counterparts. This Amendment may be executed in any number of counterparts, and by each party hereto in separate
counterparts, each of which shall be an original, but all of which shall together constitute one and the same agreement; signature pages may be detached from multiple separate counterparts and attached to a single counterpart so that all signature
pages are physically attached to the same document. This Amendment may be executed by facsimile or other electronic communication and the effectiveness of this Amendment and signatures thereon shall have the same force and effect as manually signed
originals and shall be binding on all parties thereto. The Agent may require that any such documents and signatures be confirmed by a manually-signed original thereof, provided that the failure to request or deliver the same shall not limit
the effectiveness of any facsimile or other electronic signature.
