(l)                                     To use the net proceeds received by it from the sale of the Securities pursuant to this Agreement in the manner specified in the Time of Sale Prospectus under the caption “Use of Proceeds.”

(m)                               The Company also covenants with each Underwriter that, without the prior written consent of each of the Representatives, it will not, for the period of ninety (90) days from the date of this Agreement, (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise or (3) file any registration statement with the Commission relating to the offering of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock.  The foregoing sentence shall not apply to (a) the Securities to be sold hereunder, (b) the issuance by the Company of shares of Common Stock upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof of which the Underwriters have been advised in writing, (c) any grants under the Company’s equity or stock plans in accordance with the terms of such plans as described in the Time of Sale Prospectus, (d) Common Stock or rights to receive Common Stock (including securities convertible into or exercisable or exchangeable for Common Stock) issued or contemplated to be issued in connection with an acquisition or a strategic or minority investment transaction with a customer, supplier or other business partner (or a person that becomes a business partner in connection with such a transaction) provided that the aggregate number of shares of Common Stock issued in or issuable upon the exercise of rights to receive shares of Common Stock granted in such transactions in the aggregate shall not exceed five percent (5%) of the Company’s outstanding Common Stock as of the Closing Date (it being understood that shares issued or issuable pursuant to clause (e) 

14

below shall not count against such five percent (5%) limit), (e) Common Stock or rights to receive Common Stock (including securities convertible into or exercisable or exchangeable for Common Stock) issued or contemplated to be issued in connection with an acquisition or a strategic or minority investment transaction with a customer, supplier or other business partner (or a person that becomes a business partner in connection with such a transaction), provided that, prior to or concurrently with execution of any binding agreement providing for the issuance of any such shares or rights, the entity that is issued or to be issued such Common Stock or rights to receive such Common Stock pursuant to such agreement agrees with the Company that from the date of such agreement until a date that is at least 90 days after the date of this Agreement such entity and its controlled affiliates will be subject to restrictions at least as restrictive as those set forth in the form of “lock-up” agreement attached as Exhibit A hereto solely with respect to such Common Stock received or rights to receive such Common Stock (and not with respect to other Common Stock or rights to receive Common Stock then owned or thereafter acquired by such entity or its controlled affiliates), provided, that transfers among a party to such agreements and its controlled affiliates  and among controlled affiliates will be permitted and that the exceptions provided for in the agreement attached as Exhibit A shall only apply if the party relying on such exception is an individual), (f) the concurrent issuance of 4.25% Convertible Senior Notes due October 15, 2013, and shares of Common Stock issuable upon conversion thereof, as described in the Time of Sale Prospectus, or (g) the capped call transactions described in the Time of Sale Prospectus.  The Company agrees that, prior to the date that is 90 days after the date of this Agreement, without the prior written consent of each of the Representatives, it will not waive any of the restrictions set forth in any of the lock-up agreements that qualify an issuance for the exception set forth in clause (e) of the preceding sentence.

7.                                       Covenants of the Underwriters.  Each Underwriter severally covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter.

8.                                       Indemnity and Contribution.  (a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of the Underwriters and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action

15

or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, (and other than with respect to the Registration Statement, in light of the circumstances in which they were made) not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein.

(b)                                 Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, each of its directors, officers who sign the Registration Statement, employees and agents and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus or the Prospectus or any amendment or supplement thereto.

(c)                                  In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding.  In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, or (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to

16

the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action.  It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred.  Such firm shall be designated in writing by the Representatives in the case of parties indemnified pursuant to Section 8(a), and by the Company, in the case of parties indemnified pursuant to Section 8(b).  The indemnifying party shall not be liable for any settlement of any proceeding effected without its prior written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment.  No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d)                                 To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Securities or (ii) if the allocation provided by clause 8(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 8(d)(i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations.  The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters bear to the aggregate public offering price of the Securities set forth in the Prospectus.  The relative fault of the Company on the one hand and the

17

Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amount of Securities they have purchased hereunder, and not joint.

(e)                                  The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8(d).  The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f)                                    The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any director, officer, employee, agent or affiliate of any Underwriter or by or on behalf of the Company, its officers, directors, employees, agents, or any person controlling the Company and (iii) acceptance of and payment for any of the Securities.

9.                                       Termination.  The Underwriters may terminate this Agreement by notice given by the Representatives to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NASDAQ Global Market, the Chicago

18

Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any securities of the Company shall have been suspended on any exchange, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York or Idaho State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in the Representatives’ judgment, is material and adverse and which, singly or together with any other event specified in this clause 9, makes it, in the Representatives’ judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

10.                                 Effectiveness; Defaulting Underwriters.  This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Securities that it has or they have agreed to purchase hereunder on such date, and the number of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one tenth of the number of the Securities to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Securities set forth opposite their respective names in Schedule II bears to the number of Firm Securities set forth opposite the names of all such non defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Securities that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one ninth of such number of Securities without the written consent of such Underwriter.  If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Securities and the number of Firm Securities with respect to which such default occurs is more than one tenth of the number of Firm Securities to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Firm Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non defaulting Underwriter or the Company.  In any such case either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected.  If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Securities and the number of Additional Securities with

19

respect to which such default occurs is more than one tenth of the number of Additional Securities to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to i) terminate their obligation hereunder to purchase the Additional Securities to be sold on such Option Closing Date or ii) purchase not less than the number of Additional Securities that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default.  Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

11.                                 Entire Agreement.  (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Securities, represents the entire agreement between the Company and the Underwriters with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Securities.

(b)                                 The Company acknowledges that in connection with the offering of the Securities: (i) the Underwriters have acted at arms length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Underwriters owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters may have interests that differ from those of the Company.  The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.

12.                                 Counterparts.  This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

13.                                 Applicable Law.  This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

Final Term Sheet

Micron Technology, Inc.

60,240,000 Shares of Common Stock

This term sheet to the preliminary prospectus supplement dated April 7, 2009 should be read together with the preliminary prospectus supplement before making a decision in connection with an investment in the securities.  The information in this term sheet supersedes the information contained in the preliminary prospectus supplement to the extent that it is inconsistent therewith.  Terms used but not defined herein have the meaning ascribed to them in the preliminary prospectus supplement.

Concurrent Offering of Convertible Senior Notes

Concurrently with this offering of common stock, pursuant to a separate prospectus supplement, we priced an underwritten public offering of $200 million aggregate principal amount of 4.25% convertible senior notes due October 15, 2013 (or $230 million aggregate principal amount of 4.25% convertible senior notes due October 15, 2013 if the underwriters exercise their over-allotment option in full) (the “Convertible Senior Notes Offering”).  Neither the completion of this offering nor of the Convertible Senior Notes Offering is contingent on the completion of the other.  Assuming no exercise of the underwriters’ over-allotment option with respect to the Convertible Senior Notes Offering, the net proceeds of the Convertible Senior Notes Offering, after deducting the underwriting discount and estimated expenses, will be approximately $194.2 million.

The convertible senior notes will be convertible at the holder’s option into shares of the Issuer’s common stock at a conversion rate of 196.7052 shares of common stock per $1,000 principal amount of convertible senior notes, which is equivalent to a conversion price of approximately $5.08 per share of the Issuer’s common stock, subject to adjustment in certain circumstances.  This initial conversion price represents a premium of approximately 22.50% relative to the public offering price of the Issuer’s common stock of $4.15 per share.

In connection with the Convertible Senior Note Offering, the Issuer entered into capped call transactions with counterparties, which are affiliated with some of the underwriters of the offering.  The capped call transactions cover, subject to anti-dilution adjustments, approximately 39.3 million shares (or approximately 45.2 million shares if the underwriters of the Convertible Senior

I-2

Notes Offering exercise their over-allotment option in full) of the Issuer’s common stock. The Issuer estimates the cost of the capped call transactions to be approximately $21.5 million, or $24.7 million if the underwriters of the Convertible Senior Notes Offering exercise their over-allotment option in full. The capped call transactions are expected to reduce the potential dilution upon conversion of the convertible senior notes. The capped call transactions have a capped price that is 60% higher than the public offering price of the Issuer’s common stock in this offering. In connection with establishing their initial hedge of these capped call transactions, the Issuer expects that the counterparties will enter into various over-the-counter derivative transactions with respect to the Issuer’s common stock concurrently with, or shortly after, the pricing of the convertible senior notes and may unwind or enter into various over-the-counter derivatives and/or purchase the Issuer’s common stock in secondary market transactions after the pricing of the convertible senior notes. These activities could have the effect of increasing or preventing a decline in the price of the Issuer’s common stock concurrently with or following the pricing of the convertible senior notes. In addition, the counterparties may modify or unwind their hedge positions by entering into or unwinding various derivative transactions and/or purchasing or selling the Issuer’s common stock in secondary market transactions prior to maturity of the convertible senior notes (and are likely to do so on each exercise date of the capped call transactions).

Ladies and Gentlemen:

The undersigned understands that each of Goldman, Sachs & Co. and Morgan Stanley & Co. Incorporated (each, a “Representative”) proposes to enter into an Underwriting Agreement (the “Equity Underwriting Agreement”) with Micron Technology, Inc., a Delaware corporation (the “Company”), providing for the public offering (the “Public Equity Offering”) by the several underwriters, including the Representatives (the “Equity Underwriters”) of shares of the Company’s common stock, par value $0.10 per share (the “Common Stock”), and an Underwriting Agreement (the “Convertible Senior Note Underwriting Agreement” and, together with the Equity Underwriting Agreement, the “Underwriting Agreements”) with the Company providing for the public offering (the “Public Convertible Senior Note Offering” and, together with the Public Equity Offering, the “Public Offerings”) by the several underwriters, including the Representatives (the “Convertible Senior Note Underwriters” and, together with the Equity Underwriters, the “Underwriters”), of convertible senior notes of the Company that will be convertible into shares of Common Stock.

Whether or not the Public Offerings actually occur depends on a number of factors, including market conditions.  Any Public Offering will only be made pursuant to the Underwriting Agreements, the terms of which are subject to negotiation between the Company and the Underwriters.

(i)                                  The Company has been duly incorporated, is validly existing as a corporation in good standing under the laws of the State of Delaware and has the corporate power and authority to own its properties and to conduct its business as described in the Time of Sale Prospectus and the Prospectus;

(iv)                              The Underwriting Agreement has been duly authorized, executed and delivered by the Company;

(v)                                 None of the execution, delivery and performance of this Agreement, the issuance and sale of the Securities, or the consummation of any other of the transactions contemplated thereby will conflict with, result in a breach or violation of any of the terms or provisions of, or constitute a default under (A) the charter or by-laws of the Company or (B) any statute, decree, regulation or order known to such counsel to be applicable to the Company of any Delaware court, governmental authority or agency having jurisdiction over the Company or any of its properties or assets, except such conflicts, breaches, violations or defaults in clause (B) above as would not have a material adverse effect on the Company’s ability to perform its obligations under such agreements or to consummate the transactions contemplated thereby;

(i)                                      the Registration Statement at the time each part became effective contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading (other than the financial statements and related schedules and the financial and statistical data based on or derived from such financial statements or schedules, as to which such counsel expresses no belief);

(ii)                                   the Time of Sale Prospectus, together with the documents listed on an exhibit to such counsel’s opinion, all considered together, as of          P.M. (New York City time) on April    , 2009, and the date of such counsel’s opinion contained an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading (other than the financial statements and related schedules and the financial and statistical data based on or derived from such financial statements or schedules, as to which such counsel expresses no belief); or

B-2

(iii)                                the Prospectus, as of its date or as of the date of such counsel’s opinion, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading (other than financial statements and related schedules and the financial and statistical data based on or derived from such financial statements or schedules, as to which such counsel expresses no belief).

In addition, such counsel confirms to you that (i) the Registration Statement, when it became effective, (ii) the Time of Sale Prospectus, as of its date (other than the financial statements and related schedules and the financial and statistical data based on or derived from such financial statements or schedules, as to which such counsel express no belief), and (iii) the Prospectus, as of its date (other than the financial statements and related schedules and the financial and statistical data based on or derived from such financial statements or schedules, as to which such counsel expresses no belief) each appeared on their face to comply, in all material respects relevant to the offering of the Securities, as to form with the requirements of the Securities Act and the rules and regulations under the Securities Act.  For purposes of this paragraph, such counsel has assumed that the statements made in the Registration Statement, Time of Sale Prospectus and Prospectus are correct and complete.
