THIS JOINDER AGREEMENT (this “Agreement”), dated as of November 25, 2015, is by
and among PERICOM SEMICONDUCTOR CORPORATION, a California corporation
(“Pericom”), DIODES INCORPORATED, a Delaware corporation (the “Domestic
Borrower”), Diodes International B.V., a besloten vennootschap met beperkte
aansprakelijkheid organized under the laws of the Netherlands, having its
statutory seat in Amsterdam, the Netherlands and registered with the trade

Borrower (the “Subsidiary Guarantors”) and Bank of America, N.A., in its

“Credit Agreement”) among the Borrowers, the Subsidiary Guarantors, the Lenders
thereto and the Administrative Agent. Capitalized terms used herein but not
otherwise defined shall have the meanings provided in the Credit Agreement.

Pericom is a Domestic Subsidiary of a Loan Party, and, consequently, the

Pericom to become a “Guarantor” under the Guaranty and a “Grantor” under the
Collateral Agreement.

Accordingly, Pericom and the Borrowers hereby agree as follows with the
Administrative Agent, for the benefit of the Secured Parties:

1. Guaranty Supplement.

(a) Pericom hereby acknowledges, agrees and confirms that, by its execution of
this Agreement, it is a Guarantor under the Guaranty as if it were a signatory
thereof on the Closing Date of the Credit Agreement, and (i) shall comply with,
and be subject to, and have the benefit of, all of the terms, conditions,
covenants, agreements and obligations set forth in the Credit Agreement
(including the Guaranty) and (ii) hereby makes each representation and warranty
set forth in the Credit Agreement (including the Guaranty).

(b) Each Borrower, each other Loan Party and Pericom hereby agrees that each
reference to a “Global Guarantor”, “Global Guarantors”, “Guarantor” or the
“Guarantors” in the Credit Agreement (including the Guaranty) and the other Loan
Documents shall include Pericom, and each reference to the “Guaranty” as used
therein shall mean the Guaranty as supplemented hereby.

2. Collateral Agreement Supplement.

(a) In order to secure the Credit Agreement in accordance with the terms
thereof, and to secure the payment and performance of all of the Obligations,
(A) Pericom hereby grants and pledges to the Administrative Agent, for the
ratable benefit of itself and the Lenders, on the terms set forth in the
Collateral Agreement, a continuing security interest in and to all of its right,
title and interest in and to all Collateral whether now or hereafter owned or
acquired by it or in which it now has or hereafter has or acquires any rights,
and wherever located (excluding, however, all Equity Interests in Subsidiaries
of Pericom that are Foreign Subsidiaries) (all such Collateral, the “New
Collateral”) and (B) the Borrowers and the Guarantors each hereby confirms and
reaffirms the security interests in and to all of the Collateral of such
Borrower or such Guarantor, as applicable, granted to the Administrative Agent,
for the ratable benefit of itself and the Lenders, under the Collateral
Agreement.

--------------------------------------------------------------------------------

(b) The security interests in the Collateral are granted as security only and
shall not subject the Administrative Agent or any Lender to, or transfer to the
Administrative Agent or any Lender, or in any way affect or modify, any
obligation or liability of the Borrowers or Pericom with respect to any of the
New Collateral or any transaction in connection therewith.

(c) Each Borrower, each other Loan Party and Pericom each hereby agrees that by
execution of this Agreement Pericom is a party to the Collateral Agreement as if
it were a signatory thereof as a Grantor on the Closing Date of the Credit
Agreement, and Pericom shall (A) comply with, and be subject to, and have the
benefit of, all of the terms, covenants, conditions, agreements and obligations
set forth in the Collateral Agreement and (B) hereby makes each representation
and warranty set forth in the Collateral Agreement applicable to a “Grantor”.
The Loan Parties and Pericom each hereby agrees that each reference to a
“Grantor” or the “Grantors” in the Collateral Agreement and the other Loan
Documents shall include Pericom.

(d) Each Borrower, each other Loan Party and Pericom each hereby agrees that
“Collateral” as used in the Collateral Agreement and the Credit Agreement shall
include all New Collateral and “Collateral Agreement” or “Agreement” as used
therein shall mean the Collateral Agreement as supplemented hereby.

(e) Each Borrower, each other Loan Party and Pericom each hereby agrees that
they shall deliver to the Administrative Agent such certificates and other
documents (including, without limitation, UCC-1 Financing Statements) and take
such action as the Administrative Agent shall reasonably request in order to
effectuate the terms hereof and the Collateral Agreement.

(f) Pericom hereby acknowledges receipt of a copy of the Collateral Agreement,
the Guaranty and the other Loan Documents to which it is a party and agrees for
the benefit of the Administrative Agent and the Lenders to be bound thereby and
to comply with the terms thereof insofar as such terms are applicable to it.

(g) Attached as Annex A are updated Schedules to the Credit Agreement and
updated Schedules to the Collateral Agreement, setting forth all information
required to be provided therein with respect to Pericom and its Subsidiaries
(which information shall be provided as of the date hereof).
