This First Supplemental Indenture (this Supplemental Indenture), dated as of February 28, 2025, is entered into by and
among Infinera Corporation, a Delaware corporation (Infinera) and U.S. Bank Trust Company, National Association, a national banking association, as trustee hereunder (the Trustee). Capitalized terms used herein
and not otherwise defined herein have the meanings set forth in the Indenture referred to below.
WHEREAS, Infinera and the Trustee are
parties to that certain Indenture, dated as of August 8, 2022 (the Indenture), relating to the issuance of the 3.75% Convertible Senior Notes due 2028 (the Notes);
WHEREAS, Infinera, Nokia Corporation, a company incorporated under the laws of the Republic of Finland (Nokia), and
Neptune of America Corporation, a Delaware corporation and an indirect wholly owned subsidiary of Nokia (Merger Sub), have entered into an Agreement and Plan of Merger, dated as of June 27, 2024 (the Merger
Agreement), pursuant to which Merger Sub will merge with and into Infinera, with Infinera being the surviving entity and becoming a wholly owned subsidiary, directly or indirectly, of Nokia (the Merger). Each share of
Infineras common stock, par value $0.001 per share (the Common Stock) issued and outstanding immediately prior to the effective time of the Merger will be cancelled, extinguished and converted into the right to receive
(i) cash in an amount equal to $6.65, without interest, (ii) 1.7896 American Depositary Shares of Nokia (each representing a beneficial interest in one ordinary share of Nokia, with no nominal value (Nokia Shares)) or
(iii) cash in an amount equal to $4.66, without interest, and 0.5355 Nokia Shares, in each case as set forth in the Merger Agreement;
WHEREAS, Section 13.07 of the Indenture provides, among other things, that in the event of a consolidation, merger or combination
involving Infinera, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a Merger Event),
then Infinera or the successor or purchasing company, as the case may be, will execute with the Trustee and without the consent of the Holders, a supplemental 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 shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the Reference Property, with each unit of
Reference Property meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon such Merger Event; provided, however, that at and after the effective time of the
Merger Event the Conversion Obligation shall be calculated and settled in accordance with Section 13.02 of the Indenture such that (A) the amount otherwise payable in cash upon conversion of the Notes as set forth under Section 13.02
of the Indenture shall continue to be payable in cash, (B) the Company shall continue to have the right to elect to determine the form of consideration to be paid or delivered, as the case may be, in respect of the remainder, if any, of the
Conversion Obligation in excess of the principal amount of the Notes being converted as set forth under Section 13.02 of the Indenture, (C) the number of shares of Common Stock, if any, otherwise deliverable upon conversion of the Notes in
accordance with Section 13.02 of the Indenture shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have received in such Merger Event and (D) the Daily VWAP
shall be calculated based on the value of a unit of Reference Property;
WHEREAS, Section 13.07 of the Indenture further provides
that if the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (i) the Reference
Property into which the Notes will be convertible shall be deemed to be the types and amounts of consideration actually received by the holders of Common Stock, and (ii) the unit of Reference Property for purposes of Section 13.07 of the
Indenture shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock;
WHEREAS, pursuant to
the Merger Agreement, holders of Common Stock received a weighted average of (i) $4.66 and (ii) 0.5355 Nokia Shares for each share of Common Stock outstanding immediately prior to the Merger;
WHEREAS, the Merger constitutes a Merger Event, Fundamental Change and Make-Whole Fundamental Change;
