“Rating Category” means (i) with respect to S&P, any of the following categories: XXX, XX, X, XXX, XX, X and D (or equivalent successor categories); (ii) with respect to Moody’s, any of the following categories: Baa, Ba, B, Caa, Ca, C and D (or equivalent successor categories); and (iii) the equivalent of any such category of S&P

or Moody’s used by another Rating Agency. In determining whether the rating of the Notes has decreased by one or more gradations, gradations within Rating Categories (+ and – for S&P; 1, 2 and 3 for Moody’s; or the equivalent gradations for another Rating Agency) shall be taken into account (e.g., with respect to S&P, a decline in a rating from BB+ to BB, as well as from BB- to B+, will constitute a decrease of one gradation).

“Rating Date” means the date of the first public announcement by the Company of the occurrence of a Change of Control (or pending Change of Control).

Section 1.03. Optional Redemption.

(a) The provisions of Article Three of the Base Indenture, as amended by the provisions of this First Supplemental Indenture, shall apply to the Notes with respect to this Section 1.03.

(b) The 2017 Notes shall be redeemable in whole or in part at any time prior to their maturity date, and the 2022 Notes shall be redeemable in whole or in part at any time prior to September 15, 2022, in each case at the Company’s option.

(ii) the sum of the present values of the Remaining Scheduled Payments of the 2017 Notes or the 2022 Notes to be redeemed, as the case may be, discounted to the Optional Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the Treasury Rate plus 25 basis points in the case of the 2017 Notes and 30 basis points in the case of the 2022 Notes,

plus, in addition to such Optional Redemption Price, in each case, accrued and unpaid interest thereon to, but excluding, the Optional Redemption Date.

(e) Notice of any optional redemption shall be electronically delivered or mailed at least 30 days but not more than 60 days before the Optional Redemption Date to each holder of the Notes to be redeemed; provided, however, that the Company shall notify the Trustee of the Optional Redemption Date at least 15 days prior to the date of the giving of such notice (unless a shorter notice shall be satisfactory to the Trustee). Such notice shall be provided in accordance with Section 3.02 of the Base Indenture; provided that, in lieu of mailing, notices may be electronically delivered to Holders of the Notes at their last electronic mailing addresses as they shall appear upon the Security Register. If the Optional Redemption Price cannot be determined at the time such notice is to be given, the actual Optional Redemption Price, calculated as described above in clause (b), shall be set forth in an Officers’ Certificate of the Company delivered to the Trustee no later than two (2) Business Days prior to the Optional Redemption Date. Notice of redemption having been given as provided in the Indenture, the Notes called for redemption shall, on the Optional Redemption Date, become due and payable at the Optional Redemption Price, and accrued and unpaid interest, if any, to, but excluding, the Optional Redemption Date.

Section 1.04. Additional Covenant.

The following additional covenant shall apply with respect to the Notes so long as any of the Notes remain Outstanding:

(a) Change of Control Repurchase Event.

(i) If a Change of Control Repurchase Event occurs with respect to the Notes, unless the Company shall have exercised its option to redeem the Notes in full, as set forth in Section 1.03 of this First Supplemental Indenture, or the Company shall have defeased the Notes or have satisfied and discharged the Notes, as set forth in Article XI of the Base Indenture, the Company shall make an offer (the “Change of Control Offer”) to each holder of the Notes to

repurchase any and all of such holder’s Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of Notes to be repurchased (such principal amount to be equal to $2,000 or an integral multiple of $1,000 in excess of $2,000), plus accrued and unpaid interest, if any, on the Notes to be repurchased up to, but excluding, the date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of Control Repurchase Event, or, at the option of the Company, prior to any Change of Control, but after the public announcement of such Change of Control, the Company shall mail or electronically deliver notice to the Holders of the Notes (with a copy to the Trustee), which shall (A) describe the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event; (B) offer to repurchase the Notes on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed or electronically delivered (the “Change of Control Payment Date”); (C) state the instructions, as determined by the Company, that a Holder must follow in order to have its Notes repurchased; and (iv) state that the offer to repurchase is conditioned on the Change of Control Repurchase Event, if mailed or electronically delivered prior to the date of consummation of the Change of Control. Notwithstanding the foregoing, installments of interest whose Stated Maturity is on or prior to the Change of Control Payment Date shall be payable on the applicable Interest Payment Date to the Securityholders of such Notes registered as such at the close of business on the applicable record date pursuant to the Notes and the Indenture.

(ii) On the Change of Control Payment Date, the Company shall, to the extent lawful:

(A) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

(B) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(C) deliver or cause to be delivered to the Trustee the Notes properly accepted, together with an Officers’ Certificate stating (1) the aggregate principal amount of 2017 Notes and 2022 Notes or portions of such Notes being repurchased, (2) that all conditions precedent contained herein to make a Change of Control Offer have been complied with and (3) that the Change of Control Offer has been made in compliance with the Indenture.

(iii) Notwithstanding the foregoing, the Company will not be required to make an offer to repurchase the Notes upon a Change of Control Repurchase Event, if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company

and such third party purchases all Notes properly tendered and not withdrawn under its offer.

(iv) If Holders of not less than 95% in aggregate principal amount of the applicable series of Outstanding Notes validly tender and do not withdraw such Notes in an offer to repurchase the Notes upon a Change of Control Repurchase Event and the Company, or any third party making an offer to purchase the Notes upon a Change of Control Repurchase Event in lieu of the Company pursuant to Section 1.04 purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company shall have the right, upon not less than 30 nor more than 60 days’ prior written notice, given not more than 30 days following the Change of Control Payment Date, to redeem all Notes of that series that remain outstanding following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of redemption.

(v) The Company shall comply in all material respects with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of this Section 1.04, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 1.04 by virtue of any such conflict.

Section 1.05. Events of Default.

With respect to the Notes, “Event of Default” means any one or more of the following events that has occurred and is continuing:

(a) default in the payment of the principal or any premium on any Note of that series when due (whether at maturity, upon acceleration, redemption or otherwise);

(c) failure by the Company to observe or perform any term of the Indenture (other than those referred to in (a) or (b) above and other than a covenant or agreement included in this First Supplemental Indenture not for the benefit of such series) for a period of 60 days after the Company receives a notice of default stating that the Company is in breach. The notice must be sent by either the Trustee or Holders of 25% of the principal amount of the Notes of the affected series;

(d) failure by the Company to repurchase the Notes tendered for repurchase following the occurrence of a Change of Control Repurchase Event in conformity with Section 1.04 of this First Supplemental Indenture;

(g) (i) a failure to make any payment at maturity, including any applicable grace period, of any indebtedness of the Company (other than indebtedness of the Company owing to any of its direct or indirect Subsidiaries) in an amount in excess of $100,000,000 and continuance of this failure to pay or (ii) a default on any indebtedness of the Company (other than indebtedness owing to any of its direct or indirect Subsidiaries), which default results in the acceleration of such indebtedness in an amount in excess of $100,000,000 without such indebtedness having been discharged or the acceleration having been cured, waived, rescinded or annulled, in the case of clause (i) or (ii) above, for a period of 30 days after written notice thereof to the Company by the Trustee or to the Company and the Trustee by the Holders of not less than 25% in principal amount of Outstanding Notes of such series (including any Additional Notes), provided, however, that if any failure, default or acceleration referred to in clause (i) or (ii) above ceases or is cured, waived, rescinded or annulled, then the Event of Default will be deemed cured.

This security is one of a duly authorized series of debt securities of NetApp, Inc., a Delaware corporation (the “Company”), issued or to be issued in one or more series under and pursuant to an Indenture for the Company’s unsubordinated debt securities, dated as of December 12, 2012 (the “Base Indenture”), duly executed and delivered by and among the Company and U.S. Bank National Association (the “Trustee”), as supplemented by the First Supplemental Indenture, dated as of December 12, 2012 (the “First Supplemental Indenture”), by and between the Company and the Trustee. The Base Indenture as supplemented and amended by the First Supplemental Indenture is referred to herein as the “Indenture.” By the terms of the Base Indenture, the debt securities issuable thereunder are issuable in series that may vary as to amount, date of maturity, rate of interest and in other respects as provided in the Base Indenture. This security is one of the series designated on the face hereof (individually, a “Security,” and collectively, the “Securities”), and reference is hereby made to the Indenture for a description of the rights, limitations of rights, obligations, duties and immunities of the Trustee, the Company and the holders of the Securities (the “Securityholders”). Capitalized terms used herein and not otherwise defined shall have the meanings given them in the Base Indenture or the First Supplemental Indenture, as applicable.

1. Interest. The Company promises to pay interest on the principal amount of this Security at an annual rate of 2.00%. The Company will pay interest semi-annually on June 15 and December 15 of each year (each such day, an “Interest Payment Date”). If any Interest Payment Date, Optional Redemption Date or maturity date of this Security is not a Business Day, then payment of interest or principal (and premium, if any) shall be made on the next succeeding Business Day with the same force and effect as if made on the date such payment was due, and no interest shall accrue for the period after such date to the date of such payment on the next succeeding Business Day. Interest on the Securities will accrue from the most recent date to which interest has been paid or duly provided for or, if no interest has been paid, from the date of issuance; provided that, if there is no existing Default in the payment of interest, and if this Security is authenticated between a regular record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; and provided, further, that the first Interest Payment Date shall be June 15, 2013. Interest will be calculated on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment. The Company will pay interest on the Securities (except defaulted interest), if any, to the persons in whose name such Securities are registered at the close of business on the regular record date referred to on the facing page of this Security for such interest installment. In the event that the Securities or a portion thereof are called for redemption or there is a Change of Control Offer, and the Optional Redemption Date or the Change of Control Payment Date, as applicable, is subsequent to a regular record date with respect to any Interest Payment Date and prior to such Interest

A-4

Payment Date, interest on such Securities will instead be paid upon presentation and surrender of such Securities as provided in the Indenture. The principal of and the interest on the Securities shall be payable in the coin or currency of the United States of America that at the time is legal tender for public and private debt, at the office or agency of the Company maintained for that purpose in accordance with the Indenture.

3. Paying Agent and Registrar. Initially, U.S. Bank National Association, the Trustee, will act as paying agent and Security Registrar. The Company may change or appoint any paying agent or Security Registrar without notice to any Securityholder. The Company or any of its direct or indirect wholly-owned subsidiaries may act in any such capacity.

4. Indenture. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (“TIA”) as in effect on the date the Indenture is qualified. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and TIA for a statement of such terms. The Securities are unsecured general obligations of the Company and constitute the series designated on the face hereof as the “2.00% Senior Notes due 2017”, initially limited to $750,000,000 in aggregate principal amount. The Company will furnish to any Securityholder upon written request and without charge a copy of the Base Indenture and the First Supplemental Indenture. Requests may be made to: NetApp, Inc., 000 Xxxx Xxxx Xxxxx, Xxxxxxxxx, Xxxxxxxxxx 00000, Attention: General Counsel.

The Company shall not be required to make sinking fund payments with respect to the Securities.

6. Change of Control Repurchase Event. Upon the occurrence of a Change of Control Repurchase Event, unless the Company has exercised its right to redeem this Security or the Company has defeased this Security or satisfied and discharged this Security, the holder of this Security will have the right to require that the Company purchase all or a portion (such principal amount to be equal to $2,000 or any integral multiple of $1,000 in excess of $2,000) of this Security at a purchase price equal to 101% of the principal amount repurchased plus accrued and unpaid interest, if any, on the amount to be repurchased to the date of purchase. Within 30 days following any Change of Control Repurchase Event, or, at the option of the Company, prior to any Change of Control but after the public announcement of the Change of Control, the Company shall send, by first class mail or electronic delivery, a notice to each Holder, in accordance with Section 1.04(a)(i) of the First Supplemental Indenture, with a copy to the Trustee, which notice shall govern the terms of the Change of Control Offer.

7. Denominations, Transfer, Exchange. The Securities are in registered form without coupons in the denominations of $2,000 or any integral multiple of $1,000 in

A-5

excess thereof. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. No service charge will be made for any registration of transfer or exchange, but a Securityholder may be required to pay any applicable taxes or other governmental charges. If the Securities are to be redeemed, the Company will not be required to: (i) issue, register the transfer of, or exchange any Security during a period beginning at the opening of business 30 days before the day of mailing of a notice of redemption of less than all of the outstanding Securities of the same series and ending at the close of business on the day of such mailing; (ii) register the transfer of or exchange any Security of any series or portions thereof selected for redemption, in whole or in part, except the unredeemed portion of any such Security being redeemed in part; nor (iii) register the transfer of or exchange of a Security of any series between the applicable record date and the next succeeding Interest Payment Date.

8. Persons Deemed Owners. The registered Securityholder may be treated as its owner for all purposes.

9. Repayment to the Company. Any funds or Governmental Obligations deposited with any paying agent or the Trustee, or then held by the Company, in trust for payment of principal of, premium, if any, or interest on the Securities of a particular series that are not applied but remain unclaimed by the holders of such Securities for at least one year after the date upon which the principal of, premium, if any, or interest on such Securities shall have respectively become due and payable, shall, upon request of the Company, be repaid to the Company, or (if then held by the Company) shall be discharged from such trust. After return to the Company, Holders entitled to the money or securities must look to the Company, as applicable, for payment as unsecured general creditors.

10. Amendments, Supplements and Waivers. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of a majority in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

11. Defaults and Remedies. If an Event of Default with respect to the securities of a series issued pursuant to the First Supplemental Indenture occurs and is continuing, the Trustee or the holders of at least 25% in aggregate principal amount of the Securities of such series then Outstanding, by notice in writing to the Company (and to the Trustee if notice is given by such holders), may declare the unpaid principal of,

A-6

premium, if any, and accrued interest, if any, due and payable immediately. Subject to the terms of the Indenture, if an Event of Default under the Indenture shall occur and be continuing, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request or direction of any of the holders, unless such holders have offered the Trustee indemnity satisfactory to it. Upon satisfaction of certain conditions set forth in the Indenture, the holders of a majority in principal amount of the Outstanding securities of a series issued pursuant to the First Supplemental Indenture will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the securities of such series.

12. Trustee, Paying Agent and Security Registrar May Hold Securities. The Trustee, subject to certain limitations imposed by the TIA, or any paying agent or Security Registrar, in its individual or any other capacity, may become the owner or pledgee of Securities with the same rights it would have if it were not Trustee, paying agent or Security Registrar.

13. No Recourse Against Others. No recourse under or upon any obligation, covenant or agreement of the Indenture, or of any Security, or for any claim based thereon or otherwise in respect hereof or thereof, shall be had against any incorporator, stockholder, officer or director, past, present or future as such, of the Company or of any predecessor or successor corporation, either directly or through the Company or any such predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that the Indenture and the obligations issued hereunder and thereunder are solely corporate obligations, and that no such personal liability whatever shall attach to, or is or shall be incurred by, the incorporators, stockholders, officers or directors as such, of the Company or of any predecessor or successor corporation, or any of them, because of the creation of the indebtedness authorized by the Indenture, or under or by reason of the obligations, covenants or agreements contained in the Indenture or in the Securities or implied therefrom; and that any and all such personal liability of every name and nature, either at common law or in equity or by constitution or statute, of, and any and all such rights and claims against, every such incorporator, stockholder, officer or director as such, because of the creation of the indebtedness authorized by the Indenture, or under or by reason of the obligations, covenants or agreements contained in the Indenture or in the Securities or implied therefrom, are hereby expressly waived and released as a condition of, and as a consideration for, the acceptance of the Securities.
