FIRST SUPPLEMENTAL INDENTURE, dated as of June 21, 2006 (this “First Supplemental Indenture”), between Lexar Media, Inc., a Delaware corporation (the “Company”), having its principal office at 00000 Xxxxxxx Xxxxxxx, Xxxxxxx, XX 00000 and U.S. Bank National Association, a national banking association organized under the laws of the United States, as Trustee under the Indenture referred to herein (the “Trustee”). This First Supplemental Indenture shall become effective only immediately after the closing of the Merger in accordance with the Merger Agreement.

WHEREAS, the Company and the Trustee heretofore executed and delivered an Indenture, dated as of March 30, 2005 (the “Indenture”), in respect of the 5.625% Senior Convertible Notes due 2010 (each, a “Security” and collectively, the “Securities”); and

WHEREAS, the Company has entered into an Agreement and Plan of Merger, dated as of March 8, 2006, with Micron Technology, Inc., a Delaware corporation (“Parent”), March 2006 Merger Corp. ("Merger Sub"), a Delaware corporation and direct wholly owned subsidiary of Parent (as amended through the date hereof, the "Merger Agreement"), which provides that March 2006 Merger Corp. will merge with and into the Company, the separate corporate existence of March 2006 Merger Corp. shall cease and the Company shall continue as the surviving corporation and as a wholly owned subsidiary of Parent (the “Merger”); and

WHEREAS, the Merger is expected to be consummated on June 21, 2006; and

WHEREAS, each share of Company common stock, par value $0.0001 per share, of the Company issued and outstanding immediately prior to the effective time of the Merger, other than any shares of Company common stock to be canceled pursuant to Section 1.6(c) of the Merger Agreement, will be canceled and extinguished and automatically converted into the right to receive 0.5925 (the “Exchange Ratio”) of a validly issued, fully paid and nonassessable share of the common stock, par value $0.10 per share, of Parent (subject to cash to be paid in lieu of fractional shares of Parent common stock); and

WHEREAS, Section 4.11(a)(A) of the Indenture provides that, as a condition precedent to a merger, the Company shall execute and deliver to the Trustee a supplemental indenture providing that the holder of each Security then outstanding shall have the right to convert such Security into the kind and amount of shares of stock, other securities and property (including cash) receivable upon effectiveness of such merger by a holder of a number of shares of Company common stock deliverable upon conversion of such Security immediately prior to effectiveness of such merger; and

WHEREAS, Section 4.11(a) of the Indenture further provides that such supplemental indenture executed and delivered by the Company in the case of a merger shall provide for adjustments of the Conversion Rate (as defined in the Indenture) which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Rate provided for in Article 4 of the Indenture; and

WHEREAS, Section 11.1(a)(8) of the Indenture provides that in the case of a merger, the Company and the Trustee may amend or supplement the Indenture or Securities without notice to or consent of any holder of Securities for the purpose of complying with the provisions of the Indenture in the event of a merger, consolidation or transfer of assets (including the provisions of Section 4.11 of the Indenture); and

WHEREAS the Company desires to execute and deliver this First Supplemental Indenture in accordance with Section 4.11(a)(A) of the Indenture; and

WHEREAS, this First Supplemental Indenture has been duly authorized by all necessary corporate action on the part of the Company and the Trustee; and

NOW, THEREFORE, the Company and the Trustee agree as follows that the following Sections of this First Supplemental Indenture supplement the Indenture:

ARTICLE I

ASSUMPTION BY SUCCESSOR CORPORATION

SECTION 1.1 Definitions.

(a) Capitalized terms used herein but not defined shall have the meanings ascribed to such terms in the Indenture.

(b) Section 1.1 of the Indenture is hereby supplemented and amended as follows:

The definition of “Common Stock” shall, upon consummation of the Merger, mean the common stock of Parent $0.10 par value per share as it exists on the date of this First Supplemental Indenture and any shares of any class or classes of capital stock of the Parent resulting from any reclassification or reclassifications thereof and which have no preference in respect of dividends or of amounts payable in the event of any voluntary or involuntary liquidation, dissolution or winding-up of the Parent and which are not subject to redemption by the Parent; provided, however, that if at any time there shall be more than one such resulting class, the shares of each such class then so issuable on conversion of Securities shall be substantially in the proportion which the total number of shares of such class resulting from all such reclassifications bears to the total number of shares of all such classes resulting from all such reclassifications.

The definition of “Merger” shall mean the merger of March 2006 Merger Corp., a wholly owned subsidiary of Parent, with and into the Company pursuant to that certain Agreement and Plan of Merger, dated as of March 8, 2006, as amended, by and among Parent, the Company and March 2006 Merger Corp., with the Company continuing as the surviving corporation and as a wholly owned subsidiary of Parent.
