 RECITALS 

WHEREAS, the Company and the Trustee are parties to an Indenture, dated as of September 12, 2016 (the
“Indenture”), pursuant to which the Company issued its 0.75% Convertible Senior Notes due 2021 (the “Notes”); 

WHEREAS, on October 29, 2020, Marvell Technology Group Ltd., a Bermuda exempted company (“Marvell”), Marvell
Technology (a wholly owned subsidiary of Marvell), Maui Acquisition Company Ltd, a Bermuda exempted company and a wholly owned subsidiary of Marvell Technology (“Bermuda Merger Sub”), Indigo Acquisition Corp., a Delaware
corporation and a wholly owned subsidiary of Marvell Technology (“Delaware Merger Sub”), and the Company, entered into an agreement and plan of merger and reorganization (the “Merger Agreement”); 

WHEREAS, pursuant to the Merger Agreement and a statutory merger agreement complying with the requirements of Section 105 of the
Companies Act 1981 of Bermuda, as amended (the “Statutory Merger Agreement”), Marvell will acquire the Company in a cash and stock transaction through (1) the merger of Bermuda Merger Sub with and into Marvell (the
“Bermuda Merger”) and (2) the merger of Delaware Merger Sub with and into the Company (the “Delaware Merger” and, together with the Bermuda Merger, the “Mergers”); 

WHEREAS, as a result of the Mergers, which will become effective within one minute of each other, Marvell and the Company will become wholly
owned subsidiaries of Marvell Technology, a new holding company; 
 WHEREAS, at the effective time of the Delaware Merger (the
“Effective Time”), each share of common stock, $0.001 par value per share, of the Company (each, an “Inphi Share”) issued and outstanding immediately prior to the Effective Time (other than
(i) Inphi Shares held by the Company, Marvell, Marvell Technology, Delaware Merger Sub or any other subsidiary of Marvell or the Company and (ii) Inphi Shares with respect to which appraisal rights are properly exercised and not withdrawn
under Delaware law) will be converted into the right to receive 2.323 shares of common stock, $0.002 par value per share, of Marvell Technology (“Marvell Technology Common Stock”) and $66.00 in cash, without interest, plus
cash in lieu of any fractional Marvell Technology Common Stock; 
 WHEREAS, Section 14.07(a) of the Indenture provides, among other
things, that, upon the occurrence of a Merger Event, the Company shall execute with the Trustee a supplemental indenture permitted under Section 10.01(g) of the Indenture providing that, at and after the effective time of such Merger Event, the
right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the kind and amount 











 
of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of Inphi Shares equal to the Conversion Rate immediately
prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”) upon such Merger Event; provided, however, that at and after the effective time of such Merger Event (A) the
Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 14.02 of the Indenture and (B) (I) any amount payable in cash
upon conversion of the Notes in accordance with such Section 14.02 shall continue to be payable in cash, (II) any Inphi Shares that the Company would have been required to deliver upon conversion of the Notes in accordance with such
Section 14.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of Inphi Shares would have been entitled to receive in such Merger Event and (III) the Daily VWAP shall be calculated
based on the value of a unit of Reference Property.  
 WHEREAS, the Delaware Merger constitutes a Make-Whole Fundamental Change and
a Merger Event under the Indenture; 
 WHEREAS, Marvell Technology wishes to fully and unconditionally guarantee all of the obligations of
the Company under the Notes and the Indenture (the “Guarantee”); 
 WHEREAS, in accordance with
Section 10.01(g) of the Indenture, the Company and the Trustee may enter into this Supplemental Indenture without the consent of any Holder to provide that the Notes are convertible into Reference Property, subject to the provisions of
Section 14.02 of the Indenture, and to make such related changes to the terms of the Notes to the extent expressly required by Section 14.07 of the Indenture; 

WHEREAS, in accordance with Section 10.01(c) of the Indenture, the Company and the Trustee may enter into this Supplemental Indenture
without the consent of any Holder, to add guarantees with respect to the Notes; 
 WHEREAS, the Company has pursuant to Sections 10.05,
14.07(b) and 17.05 of the Indenture heretofore delivered or is delivering contemporaneously herewith to the Trustee an Officer’s Certificate and an Opinion of Counsel; and
