and among Novatel Wireless, Inc., a Delaware corporation (the “Issuer”), Inseego Corp., a Delaware corporation (“Inseego”), and Wilmington Trust, National Association, a national banking association, as trustee
hereunder (“Trustee”). Capitalized terms used herein and not otherwise defined herein shall have the meanings ascribed thereto in the Indenture (as defined below). 

RECITALS 
 WHEREAS, the Issuer
and the Trustee are parties to an Indenture, dated as of June 10, 2015 (the “Indenture”), which Indenture governs the 5.50% Convertible Senior Notes due 2020 (the “Notes”) issued under and in accordance with the
provisions of the Indenture; 
 WHEREAS, as of the date of this First Supplemental Indenture, there is $120 million aggregate principal
amount of the Notes outstanding; 
 WHEREAS, the Issuer, Inseego and Vanilla Merger Sub, Inc., a Delaware corporation and wholly-owned
subsidiary of Inseego (“Merger Sub”), are parties to that certain Agreement and Plan of Merger, dated as of November 7, 2016, pursuant to which Merger Sub merged with and into the Issuer, with the Issuer surviving as a
wholly-owned subsidiary of Inseego (the “Merger”); 
 WHEREAS, at the effective time of the Merger (the “Effective
Time”), each share of common stock of the Issuer issued and outstanding immediately prior to the Effective Time was converted into a share of common stock of Inseego (“Inseego Common Stock”), having the same designations,
rights, powers, preferences, qualifications, limitations and restrictions, as a share of common stock of the Issuer converted; 
 WHEREAS,
the Merger will constitute a Common Stock Change Event under Section 10.08 of the Indenture and as a result of such Common Stock Change Event, the Notes will become convertible into shares of Inseego Common Stock on identical terms that the Notes
were convertible into shares of Common Stock immediately prior to the Merger; 
 WHEREAS, as a result of the Merger, Inseego is required to
execute and deliver with the Trustee a supplemental indenture providing for the conversion and settlement of the Notes into shares of Inseego Common Stock as set forth in the Indenture and providing for adjustments that shall be as nearly as
equivalent as possible to the adjustments provided for in Article 10 of the Indenture; 
 WHEREAS, Section 9.01(k) of the Indenture provides
that, without the consent of any Holder, the Issuer and the Trustee may enter into one or more supplemental indentures in connection with a Common Stock Event; 

WHEREAS, the Issuer, Inseego and the Trustee desire to enter into this First Supplemental Indenture to evidence Inseego’s obligation to
issue shares of Inseego Common Stock upon the conversion of the Notes, in each case in accordance with the provisions of the Indenture; and 







 WHEREAS, all things necessary to make this First Supplemental Indenture when executed by the
parties hereto a valid supplement to the Indenture according to its terms and the terms of the Indenture have been done and performed. 

NOW, THEREFORE, the parties hereto covenant and agree for the benefit of all holders of the Notes, as follows: 

ARTICLE ONE 
 EFFECT OF
THE MERGER 
 Section 101    Conversion to Inseego Common Stock. From and after the Effective Time, the
consideration due upon the conversion of any Notes, and the conditions to any such conversion, will be determined in the same manner as if each reference to any number of shares of Common Stock in Article 10 of the Indenture were instead a reference
to the same number of shares of Inseego Common Stock. Inseego agrees to be bound by all the terms, provisions and conditions of the Indenture and the Notes and agrees that for purposes of the conversion of the Notes in accordance with Article
10 of the Indenture it shall be assuming the obligations of the Issuer under the Indenture to issue shares of Inseego Common Stock pursuant to and in accordance with Article 10 of the Indenture. 

Section 102    Adjustment of Conversion Rate. All anti-dilution and other adjustments to the Notes set forth
in Article 10 of the Indenture shall continue in the same manner as if each reference to any number of shares of Common Stock in Article 10 of the Indenture were instead a reference to the same number of shares of Inseego Common Stock. 

Section 103    References to Common Stock. From and after the Effective Time, all references in the Indenture
and the Notes to “Common Stock” shall refer to the Inseego Common Stock instead of shares of the common stock of the Issuer.
