AGREEMENTS

In consideration of the premises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

1 Amendments to the Operative Documents.

(A) Amendments to the Closing Certificate. Effective as of the Amendment Date, but subject to the satisfaction of the condition precedent set forth in Section 9 below, the Closing

Certificate is hereby amended as follows:

(1) The definition of “Consolidated EBITDA” in Subparagraph 3(A) of the Closing Certificate is hereby amended and restated in its entirety as follows:

“Consolidated EBITDA” means, with reference to any period, the sum of the following: (a) Consolidated Net Income for such period, plus (b) without duplication and to the extent deducted from revenues in determining such Consolidated Net Income, the sum of (i) Consolidated Interest Expense for such period, (ii) expense for taxes paid or accrued during such period, (iii) all amounts attributable to depreciation, (iv) amortization during such period, (v) extraordinary non-cash charges incurred other than in the ordinary course of business during such period, (vi) nonrecurring extraordinary non-cash restructuring charges, (vii) share-based non-cash compensation expense, and (viii) any non-cash charge with respect to the amortization of the value or cost of any derivative instrument that is excluded from the definition of “Swap Agreement” below by reason of clause (b) or clause (c) of the proviso at the end of that definition, minus without duplication and to the extent included in determining such Consolidated Net Income, (c) interest income, (d) extraordinary non-cash gains realized other than in the ordinary course of business and (e) any cash payments made during such period in respect of the item described in clause (vii) above subsequent to the fiscal quarter in which the relevant share-based non-cash compensation expense was incurred, all calculated for NAI and its Subsidiaries in accordance with GAAP on a consolidated basis. For the purposes of calculating Consolidated EBITDA for any period of four consecutive fiscal quarters (each, a “Reference Period”), (i) if at any time during such Reference Period NAI or any Subsidiary shall have made any Material Disposition, the Consolidated EBITDA for such Reference Period shall be reduced by an amount equal to the Consolidated EBITDA (if positive) attributable to the property that is the subject of such Material Disposition for such Reference Period or increased by an amount equal to the Consolidated EBITDA (if negative) attributable thereto for such Reference Period, and (ii) if during such Reference Period NAI or any Subsidiary shall have made a Material Acquisition, Consolidated EBITDA for such Reference Period shall be calculated after giving pro forma effect thereto as if such Material Acquisition occurred on the first day of such Reference Period. As used in this definition, “Material Acquisition” means any acquisition of property or series of related acquisitions of property that (a) constitutes (i) assets comprising all or substantially all or any significant portion of a business or operating unit of a business, or (ii) all or substantially all of the common stock or other Equity Interests of a Person, and (b) involves the payment of consideration by NAI and its Subsidiaries in excess of $50,000,000; and “Material Disposition” means any sale, transfer or disposition of property or series of related sales, transfers, or dispositions of property that yields gross proceeds to NAI or any of its Subsidiaries in excess of $50,000,000.

(2) The definition of “Swap Agreement” in Subparagraph 3(A) of the Closing Certificate is hereby amended and restated in its entirety as follows:

“Swap Agreement” means any agreement entered into for the primary purpose of hedging or mitigating risk or speculation with respect to any swap, forward, future or derivative transaction or option or similar agreement involving, or settled by reference to, one or more rates, currencies, commodities, equity or debt instruments or securities, or economic, financial or pricing indices or measures of economic, financial or pricing risk or value or any similar transaction or any combination of these transactions; provided that the following shall be excluded from this definition: (a) any of the foregoing involving, or settled by reference to, Equity Interests of NAI and entered into or issued in connection with compensatory arrangements for directors, officers, employees or consultants of NAI or any of the Subsidiaries, (b) any of the foregoing that is, or at the election of the issuer may be, settled (after payment of any premium for any option or any prepayment under any forward contract) through the issuance of Equity Interests of NAI, and (c) any of the foregoing to the extent it constitutes a derivative embedded in a convertible security issued by NAI that involves, or is settled by reference to, Equity Interests of NAI (including, for avoidance of doubt, “net share settled” convertible securities).

(B) Amendment to the Common Definitions and Provisions Agreement. Effective as of the Amendment Date, but subject to the satisfaction of the condition precedent set forth in Section 9 below, clause (F) of the definition of “Event of Default” in Article 1 of the Common Definitions and Provisions Agreement is hereby amended and restated in its entirety as follows:

(F) NAI or any Subsidiary of NAI fails to pay any principal of or premium or interest on any of its Indebtedness which is outstanding in a principal amount of at least $25,000,000 when the same becomes due and payable (whether by scheduled maturity, required prepayment, acceleration, demand or otherwise), and such failure continues after the applicable grace period, if any, specified in the agreement or instrument relating to such Indebtedness; or any other event occurs or condition exists under any agreement or instrument relating to any such Indebtedness and continues after the applicable grace period, if any, specified in such agreement or instrument, if the effect of such event or condition is to accelerate the maturity of such Indebtedness (other than by conversion of any convertible debt instrument pursuant to its terms); or any such Indebtedness is declared by the creditor to be due and payable, or required to be prepaid (other than by a regularly scheduled required prepayment), redeemed, purchased or defeased, or an offer to prepay, redeem, purchase or defease such Indebtedness is required to be made, in each case prior to the stated maturity thereof (other than, in each case, by conversion of any convertible debt instrument pursuant to its terms).

NAI confirms that it is, as successor by merger to Network Appliance, Inc., a party to and bound by the Operative Documents as was Network Appliance, Inc. Further, NAI ratifies and confirms all terms and conditions of the Operative Documents, as hereby amended, including the representations made by Network Appliance, Inc. concerning the Property in the Ground Lease. NAI also confirms that (a) all such representations which concern the Property would continue to be accurate and complete in all material respects if made as of the Amendment Date, and (b) NAI is not currently aware of any Default or Event of Default which has occurred and is continuing or of any defense, counterclaim, set-off, right of recoupment, abatement or other claim which NAI may now have against BNPPLC under the Operative Documents.

Without limiting the foregoing, this Amendment will be binding upon NAI when signed on behalf of NAI by Ingemar Lanevi, Vice President and Corporate Treasurer of NAI.

(2) Truth of Information.

(3) No Default or Violation. The execution and performance by NAI of this Amendment do not and will not contravene or result in a breach of or default under any other agreement to which NAI is a party or by which NAI is bound or which affects any assets of NAI. Such execution and performance by NAI do not contravene any law, order, decree, rule or regulation to which NAI is subject. Further, such execution and performance by NAI will not result in the creation or imposition of (or the obligation to create or impose) any lien, charge or encumbrance on, or security interest in, any property of NAI pursuant to the provisions of any such other agreement.

(4) Enforceability. This Amendment constitutes the legal, valid and binding obligations of NAI enforceable in accordance with its terms, subject to the effect of bankruptcy, insolvency, reorganization, receivership and other similar laws affecting the rights of creditors generally.

4 Reservation of Rights.

More specifically, the Participation Agreement defines “Majority” as parties to the Participation Agreement (i.e., Participants or BNPPLC and Participants), the aggregate Percentages of which equal or exceed sixty-seven percent (67%) of the Percentages of BNPPLC and of all the Participants then entitled to vote on certain matters specified in the Participation Agreement. For purposes of such voting, the Percentages of BNPPLC and the Participants under the Participation Agreement are currently as follows:
