ATHEROS TECHNOLOGY LTD.

VOLUME PURCHASE AGREEMENT

This Volume Purchase Agreement (this “Agreement”) is made and entered into effective as of the day of February 28, 2011, by and between Atheros Technology Ltd., a Bermuda corporation (“Atheros”) and Aruba Networks, Inc., a Delaware corporation (“Buyer”).

WHEREAS, Atheros desires to sell to Buyer, and Buyer desires to purchase from Atheros, certain semiconductor products (“Components”), subject to the terms and conditions of this Agreement.

NOW THEREFORE, in consideration of the mutual promises contained herein, it is hereby agreed as follows:

1. Scope. This Agreement shall apply to sales of Components by Atheros to Buyer. Atheros and Buyer may be referred to herein as “Party” when referred to individually and “Parties” when referred to collectively. “Components” refers only to hardware, chips and chipsets. Software, reference designs, developer’s kits, and documentation, if any, have been separately licensed under the Atheros Non-Exclusive Technology License Agreement (“Technology License Agreement”) mutually executed by Atheros’ parent corporation, Atheros Communications, Inc., and Buyer where Buyer is a licensee (“Licensee”) for Licensee’s use in integrating the Components as part of products developed by or for Licensee (“Licensee Products”).

1.1 Customizations. Buyer may request that certain customizations, such as the inclusion of certain macros, be made to the Components, which Atheros may choose to implement, subject to the following:

1.1.1 Process. If Buyer wishes Atheros to implement the customizations, Buyer and Atheros shall in good faith prepare and execute a schedule, referencing this Agreement and providing details on product pricing, non-recurring fees, customizations, and delivery schedule, at a minimum.

1.1.2 Conditions. Atheros may unilaterally reject any request for customization on commercially reasonable grounds, including but not limited to: the customizations do not fit into the architectural design and physical limits of the applicable Component; or Buyer’s current and/or projected purchases of the subject Component are insufficient to justify the request for customizations; or Atheros has slated the subject Component to become a Legacy Product (as defined in Section 2.2) within such proximity of the request for customization as to render customization not commercially reasonable.

1.2 Continuity of Supply. Atheros agrees to use commercially reasonable efforts to ship and deliver Components and customizations thereto (for orders accepted pursuant to Section 1.1 and Section 2, respectively) based on commercially reasonable lead times, from order to shipment, and to manage a die bank in support thereof.

2. Orders

2.1 Orders and Acceptance. Buyer, directly or via ODMs, assemblers and other third parties acting on Buyer’s behalf (all of which comprise “Authorized Purchasers”), may procure Components from Seller pursuant to orders issued to and accepted by Atheros. Components purchased by ODMs, assemblers and other third parties for the benefit of Buyer shall, once purchased, be deemed Components under this Agreement. Buyer will have no obligation to purchase Components from Atheros, and Atheros will have no obligation to sell Components to Buyer, except pursuant to orders accepted by Atheros. To be accepted by Atheros, an order must set forth the type and quantity of the Components to be purchased, the price, and the requested delivery dates, and may not otherwise be in nonconformance with the terms of this Agreement. Orders shall be subject to written acceptance by Atheros; any such acceptance may not be in nonconformance with the terms of this Agreement, and delivery schedules shall be established in accordance with Component availability and Buyer’s credit status. Atheros may accept orders from Buyer in Atheros’ sole discretion.

2.2 Rescheduling and Cancellation. Atheros will promptly notify Buyer if any order or part of an order cannot be filled or if there will be any delays in delivery. Atheros will use commercially reasonable efforts to ship and deliver on indicated dates but will not be liable for failure to do so. Alternatively, should Atheros find that the delivery date agreed on cannot be met, Atheros shall notify Buyer in writing, stating the cause of the delay and an estimated delivery date. Except with respect to Legacy Products (as defined in Section 2.3 below): For standard Components, Buyer may reschedule orders accepted by Atheros and scheduled for delivery, subject to the following limitations:

For Components having any customization, Buyer may reschedule orders accepted by Atheros and scheduled for delivery, subject to the following limitations:

2.3 For Legacy Products. This Section 2.3 applies to Legacy Products only and, with respect to Legacy Products, supersedes any contrary provisions of this Agreement. Legacy Products are defined as any Atheros products in their last stage of product life cycle, as designated by Atheros in its sole discretion. The work-in-process (WIP) of Legacy Products is therefore maintained at a low level, and all Legacy Products are BUILT TO ORDER ONLY. Legacy Products shall be designated by Atheros in its discretion and shall be identified as such by Atheros to Buyer from time to time in writing. Lead-times for Legacy Products are 12-14 weeks after receipt of order (ARO) and terms are NCNC (Non-cancellable, Non-changeable). Additional fees and costs associated with expedite requests (i.e., through Fab or Assembly) will be added and passed to Buyer. If Buyer cancels an order for Legacy Products, there will be an associated cancellation fee, as follows:

Cancellation fees:

2.4 Precedence. This Agreement takes precedence over Buyer’s or Seller’s additional or different terms and conditions which may be included on Buyer’s purchase order, Seller’s quotation or purchase order acknowledgement, or otherwise, to which notice of objection is hereby given, and any inconsistent or additional terms in such forms will be of no effect. Any changes to this Agreement must be specifically agreed to in writing by Atheros and Buyer.

2.5 Obsolescence. If Atheros chooses to obsolete any Components, it shall give at least six (6) months advance notice to Buyer. Buyer may place orders during the notification period for shipment no later than twelve (12) months after the notice date.

3. Delivery; Title

3.1 Delivery. Components will be delivered Ex Works (Incoterms 2000), Atheros’ designated factory dock or distribution center dock. Buyer will pay all costs relating to transportation, delivery, duties and insurance. Buyer will provide Atheros with shipping instructions on its order and if it fails to do so, Atheros will determine the carrier and means of transportation and will ship the Components freight collect. Buyer shall notify Atheros in writing of any shortage in any shipment within thirty (30) days after Buyer’s receipt of such shipment. All shipments shall be directed to a Buyer operated receiving location.

3.2 Risk of Loss. Risk of loss for the Components shall pass from Atheros to Buyer at the Atheros shipping point, and Buyer will bear the risk of loss after the shipping point and will be solely responsible for filing claims relating to any lost or damaged goods.

3.3 Title. For Components Delivered Outside of United States: Title to the Components shall pass to Buyer as follows: Atheros reserves title in the Components until paid for in full by Buyer, for the purpose of protecting Atheros’ right to receive payment under the laws of various countries. This reservation of title does not affect Buyer’s ability to transfer title to the Components in the ordinary course of its business, provided that Buyer hereby assigns in advance to Atheros any proceeds from the disposition of such Components to the extent of the amount owed to Atheros. For Components Delivered within the United States. Title to the Components shall pass from Atheros to Buyer at the Atheros shipping point. Buyer hereby grants to Atheros a purchase money security interest covering each shipment of Components made hereunder (and any proceeds derived therefrom) in the amount of Atheros’ invoice for such shipment until payment in full is received by Atheros. Buyer agrees to sign and execute any and all documents as required by Atheros to perfect such security interest.

3.4 Exporter and Importer of Record. For International Shipments, Buyer or its properly authorized agent or freight forwarder shall be the exporter of record. Buyer shall also be the importer of record and is responsible for fulfilling quota terms, obtaining import licenses, paying import license or permit fees, duties and customs fees, and any other governmental or import taxes or fees, and preparing and submitting all required documentation in connection with importing the Components.

4. Returns. No Components may be returned except under warranty or due to shipment error by Atheros. All returns must be made in accordance with Atheros’ then-current Return Material Authorization (“RMA”) procedures or such other procedures as are expressly agreed to in writing by an authorized representative of Atheros (“Atheros RMA Procedures”). Atheros shall have no responsibility or liability for returns not made in accordance with such Atheros RMA Procedures. A summary of Atheros RMA Procedures as of the Effective Date is attached hereto as Exhibit A. Changes to RMA Procedures shall take effect thirty (30) days after written notice and shall apply only to orders placed after such notice period.

5. Prices; Payment; Taxes; Rebates

5.1 Prices. Pricing is stated in a written price quote from the designated Atheros Account Manager (or a designated substitute) to Buyer. Atheros may change its prices at any time, although such changes shall not alter accepted purchase orders. All prices are in U.S. dollars.

5.2 Payment. Provided that Buyer receives written approval of the extension of credit terms from Atheros’ credit department, payment terms are net thirty(30) days from the date of invoice unless otherwise specified in writing from Atheros. Buyer must give Atheros written notice of any discrepancies among the purchase order, the invoice, and the Components received, within thirty (30) days after receipt of the Components or the invoice, whichever occurs later. Payment is not conditioned upon the Components meeting any acceptance testing procedures or criteria. If there is any dispute as to a part of a shipment, Buyer will pay for the undisputed part of that shipment. All payments to Atheros shall be in U.S. dollars, free of any restrictions or withholdings. In the event that Buyer has a delinquent balance with Atheros, Atheros may require payment in advance by wire transfer, confirmed irrevocable letter of credit, or such other means as are acceptable to Atheros, with respect to any past, pending or subsequent purchase orders until the delinquent balance is paid in full.

5.3 Intentionally omitted.

5.4 Taxes. Buyer is responsible for payment of all taxes of every kind imposed in connection with the sale to Buyer of Components or which Atheros may incur in respect of this Agreement (except for taxes imposed on Atheros’ net income) and any penalties, interest and collection or withholding costs associated with any of the foregoing items. All such amounts are in addition to other amounts payable hereunder. Under no circumstances shall Buyer pay less to Atheros than would otherwise be due if any such taxes or fees are required to be withheld by Buyer from payments to Atheros. Buyer may provide Atheros with a tax exemption certificate acceptable to the taxing authorities in lieu of paying certain taxes; however, Buyer shall reimburse Atheros for any fines, penalties, taxes and other charges, including expenses incurred by Atheros, due to Buyer’s submission of invalid information.

5.5 Rebates. If a rebate applies, the payment of any such rebate will be subject to the following terms: (i) by the first day of each calendar month, Buyer shall submit to Atheros a consumption report stating the number of Components purchased and received by Buyer from its board supplier (or, if applicable, directly from Atheros) during the immediately preceding month, together with supporting documentation acceptable to Atheros in its discretion; (ii) as soon as practicable after the beginning of each calendar quarter, Buyer and Atheros will cooperate in good faith to agree upon the rebate amount for the previous quarter, based on the above monthly consumption reports and supporting documentation delivered by Buyer for such quarter, and Buyer shall issue an invoice to Atheros for such agreed-upon rebate amount; (iii) if Buyer is a direct customer of Atheros, Buyer must deliver to Atheros the above monthly information and a mutually agreed-upon invoice for the rebate amount as provided above, no later than 180 days after Atheros has delivered to Buyer the Components to which such rebate amount applies; (iv) if Buyer has purchased Components from a board supplier, Buyer must deliver to Atheros the above monthly information and a mutually agreed-upon invoice for the rebate amount as provided above, no later than 180 days after the board supplier has delivered to Buyer the Components to which such rebate amount applies; and (v) rebates are only payable with respect to Components for which Atheros has received payment from Buyer or Buyer’s board supplier, as applicable.
