ARTICLE III 

CONVERSION OF EXISTING TERM LOANS AND ADDITIONAL TERM LOANS 
 SECTION 3.1 Agreement to Conversion of Existing Term Loans into New Term Loans. On the terms and subject to the satisfaction (or waiver) of the conditions set forth in Article IV hereof,
each Converting Term Lender agrees that an aggregate principal amount of its Existing Term Loans equal to the amount notified to such Converting Term Lender by the Administrative Agent will be converted into New Term Loans (the “Converted
Term Loans”) as of the First Amendment Effective Date. 
 SECTION 3.2 Agreement to Make Additional Term Loans.
On the terms and subject to the satisfaction (or waiver) of the conditions set forth in Article IV hereof, each Additional Term Lender agrees to make Additional Term Loans equal to the amount notified to such Additional Term Lender by the
Administrative Agent (but in no event greater than the amount such Person committed to make as Additional Term Loans) on the First Amendment Effective Date and shall be a “Lender” under the Credit Agreement as of such date. 

SECTION 3.3 Other Provisions. On the First Amendment Effective Date, the Borrower shall apply the proceeds of the Additional Term
Loans (if any), together with available cash, to (i) prepay in full all Existing Term Loans, other than Converted Term Loans, (ii) pay all accrued and unpaid interest on the aggregate principal amount of the Existing Term Loans being so
prepaid, (iii) pay to each Existing Term Lender all amounts payable pursuant to Section 4.11 of the Credit Agreement as a result of the prepayment of such Lender’s Existing Term Loans (treating Converted Term Loans as not having been
prepaid for purposes of such Section) and (iv) pay to all Non-Converting Term Lenders all indemnities, cost reimbursements and other Obligations then owed to the Non-Converting Term Lenders under the Credit Agreement. The repayment of the
Existing Term Loans contemplated hereby constitutes a voluntary prepayment by the Borrower pursuant to Section 4.1 of the Credit Agreement. Upon the First Amendment Effective Date, each Existing Term Lender will be deemed to have waived any
prior notice of such prepayment otherwise required pursuant to the Credit Agreement. The commitments of the 

  

Microsemi – Amendment No. 1

Additional Term Lenders and the conversion undertakings of the Converting Term Lenders are several and no such New Term Lender will be responsible for any other New Term Lender’s failure to
make or acquire by conversion New Term Loans. Notwithstanding anything herein or in the Credit Agreement to the contrary, the aggregate principal amount of the New Term Loans will not exceed the aggregate principal amount of the Existing Term Loans
outstanding immediately prior to the First Amendment Effective Date. Each of the parties hereto acknowledges and agrees that the terms of this Amendment do not constitute a novation but, rather, an amendment of the terms of a pre-existing
Indebtedness and related agreement, as evidenced by the Existing Credit Agreement.

 8 







 
such representations and warranties shall be true and correct in all material respects on and as of such specific date); 

(b) no order, judgment or decree of any Governmental Authority applicable to any Group Member purports to restrain any
New Term Lender from making any extension of credit to be made by it; 
 (c) no Default or Event of Default has
occurred and is continuing on the date hereof or after giving effect to the extensions of credit requested to be made on the date hereof; 
 (d) this Amendment has been duly authorized, executed and delivered by the Borrower and constitutes a legal, valid and binding obligation of the Borrower, enforceable against it in accordance with its
terms, except to the extent the enforceability hereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles
(whether enforcement is sought by proceedings in equity or at law); and 
 (e) the execution, delivery and
performance by the Borrower of this Amendment, the extensions of credit requested hereby and the use of proceeds thereof will not (a) violate its Organizational Document, (b) violate any Requirement of Law, Governmental Authorization
or any Contractual Obligation of any Group Member and (c) result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to its Organizational Documents, any Requirement of Law or any

 SECTION 5.2 Non-Impairment, etc. After giving effect to this Amendment, neither the modification of the Existing

granted pursuant to the Security Documents (as in effect immediately prior to the First Amendment Effective Date, the “Existing Security Documents”), and such Liens continue unimpaired with the same priority to secure repayment of
all Obligations, whether heretofore or hereafter incurred. Neither the modification of the Existing Credit Agreement nor the execution, delivery, performance or effectiveness of this Amendment requires that any new filings be made or other action
taken to perfect or to maintain the perfection of such Liens. Under the foregoing circumstances, the position of the Lenders with respect to such Liens, the Collateral (as defined in the Existing Security Documents) in which a security interest was
granted pursuant to the Existing Security Documents, and the ability of the Administrative Agent to realize upon such Liens pursuant to the terms of the Security Documents have not been adversely affected in any

or modification of any other term or provision of the Credit Agreement, any other Loan Document referred to therein or herein or of any transaction or further or future action on the part of the Borrower or any other Subsidiary Guarantor which would
require the consent of any of the Lenders under the Credit Agreement or any of the other Loan Documents.
