The Offer is being made pursuant to an Agreement and Plan of Merger, dated as of August 15, 2010 (as it may be amended, supplemented or otherwise modified from time to time, the “Merger Agreement”), by and among Dell, the Purchaser and 3PAR. The Merger Agreement provides, among other things, for the making of the Offer and also provides that following the consummation of the Offer and subject to certain conditions, the Purchaser will be merged with and into 3PAR (the “Merger”), with 3PAR continuing as the surviving corporation and an indirect, wholly-owned subsidiary of Dell.

We or our nominees are the holder of record of Shares held for your account. A tender of such Shares can be made only by us as the holder of record and pursuant to your instructions. The Letter of Transmittal is furnished to you for your information only and cannot be used by you to tender Shares held by us for your account.

We request instructions as to whether you wish us to tender any or all of the Shares held by us for your account, upon the terms and subject to the conditions set forth in the enclosed Offer to Purchase and the Letter of Transmittal.

Please note carefully the following:

1. The offer price for the Offer is $18.00 per Share, or any higher per Share price paid in the Offer, net to you in cash, without interest thereon and less any applicable withholding or stock transfer taxes.

2. The Offer is being made for all outstanding Shares.

3. The Offer and withdrawal rights will expire at 12:00 midnight, New York City time, on Monday, September 20, 2010 unless the Offer is extended by the Purchaser in accordance with the Merger Agreement.

4. The Offer is subject to certain conditions described in Section 15 — “Certain Conditions of the Offer” of the Offer to Purchase.

5. Tendering stockholders who are registered stockholders or who tender their Shares directly to BNY Mellon Shareholder Services (the “Depositary”) will not be obligated to pay any brokerage commissions or fees, solicitation fees, or, except as set forth in the Offer to Purchase and the Letter of Transmittal, stock transfer taxes on the Purchaser’s purchase of Shares pursuant to the Offer.

If you wish to have us tender any or all of your Shares, please so instruct us by completing, executing, detaching and returning to us the Instruction Form on the detachable part hereof. An envelope to return your instructions to us is enclosed. If you authorize tender of your Shares, all such Shares will be tendered unless otherwise specified on the Instruction Form.

Your prompt action is requested. Your Instruction Form should be forwarded to us in ample time to permit us to submit the tender on your behalf before the expiration of the Offer.
