AGREEMENT
AMENDMENT NO. 7 TO CREDIT AGREEMENT AND AMENDMENT TO GUARANTEE AND COLLATERAL
AGREEMENT, dated as of December 18, 2015 (the “Amendment”), to (i) the Amended
and Restated Credit Agreement, dated as of October 13, 2011, and as amended and
supplemented prior to the date hereof (the “Existing Credit Agreement”), among
MICROSEMI CORPORATION, a Delaware corporation (the “Borrower”), the LENDERS
party thereto (the “Lenders”), BANK OF AMERICA, N.A., as administrative agent
for the Lenders (in such capacity, the “Administrative Agent”), BANK OF AMERICA,
N.A., as collateral agent (in such capacity, the “Collateral Agent”) for the
Secured Parties, and (ii) the Guarantee and Collateral Agreement, dated as of
November 2, 2010, and as amended and supplemented prior to the date hereof (the
“Existing Guarantee and Collateral Agreement”), among the Borrower, the other
grantors from time to time party thereto (the “Subsidiary Guarantors”), and the
Collateral Agent.
A.    The Borrower has requested that the Existing Credit Agreement be amended
to, among other things, permit the Borrower, at its election, to issue and sell
certain senior unsecured notes due 2024 providing for gross proceeds of up to
$500.0 million (the “Senior Notes”) pursuant to a 144A and/or Regulation S
offering, or other private placement. The proceeds of which, if such Senior
Notes are issued, will be used to fund a portion of the Borrower’s announced
acquisition (the “Acquisition”) of PMC-Sierra, Inc., a Delaware corporation, or
a special mandatory redemption of the Senior Notes in the event the Acquisition
is not consummated.
B.    The Borrower and the Subsidiary Guarantors have requested that the
Existing Guarantee and Collateral Agreement be amended to exclude from the
definition of Collateral a segregated deposit account (the “Senior Notes
Proceeds Account”) into which the proceeds of the Senior Notes, if issued, shall
be required to be deposited prior to the consummation of the Acquisition.
C.    Each Lender (such term and each other capitalized term used but not
defined herein having the meaning given it in the Amended Credit Agreement (as
defined below)) that executes and delivers a consent to this Amendment in the
form of the “Lender Consent” attached hereto (a “Lender Consent”) will be deemed
to have agreed to the terms of this Amendment (each such Lender, a “Consenting
Lender”).
D.    The Borrower and the Requisite Lenders (as defined below) desire to amend
the Existing Credit Agreement as set forth in this Amendment, and the Borrower,
the Subsidiary Guarantors and the Requisite Lenders desire to amend the Existing
Guarantee and Collateral Agreement, in each case, subject to the satisfaction of
the conditions precedent to effectiveness referred to in Section 4 hereof.
Accordingly, in consideration of the mutual agreements herein contained and
other good and valuable consideration, the sufficiency and receipt of which are
hereby acknowledged, the parties hereto agree as follows:
