WHEREAS, CommVault and Dell wish to amend the Agreement and replace all Pricing Supplements, as set forth in Addendum #10 dated October 1, 2008 and also wish to modify the rebate and MDF provisions set forth in Addendum #9 dated September 1, 2008.

NOW THEREFORE, in consideration of the mutual covenants and promises set forth herein and for other good and valuable consideration, the receipt of which both parties hereby acknowledge, Dell and CommVault agree as follows:

The rebate and MDF terms introduced in Addendum #9, and the pricing terms introduced in Addendum #10, shall be deleted in their entirety and replaced with the following:

2.  Quarterly MDF

For all Licensed Products distributed by Dell, Dell shall earn MDF equal to [***] (“MDF Percentage”) of the aggregate quarterly software royalties paid by Dell, (column C of Exhibit A) as reported on the royalty report.

2.1  Terms and conditions of MDF

i. Licensor will provide the MDF in the form of reimbursement for specific, identifiable and mutually agreed marketing expenses incurred by Dell and/or Licensor.

ii. The parties shall meet quarterly to determine the subsequent period marketing activities to which the Quarterly MDF shall be applied (“Reimbursable Activities”). The MDF may only be applied to Reimbursable Activities approved by Licensor.

iii. Dell will provide backup documentation supporting its payment requests for Reimbursable Activities. Dell payment requests shall be consistent with the Proof of Compliance form, attached as Exhibit B to this Addendum. Licensor may only request backup documentation in accordance with the Proof of Compliance form in Exhibit B and relative to Dell’s current or past immediate quarter’s marketing activities. Licensor reserves the right to deny any claims where required documentation for reimbursement is not available or incomplete. Licensor shall provide email acceptance from a designated authorized person of Proof of Compliance forms submitted by Dell. Upon acceptance, the Proof of Compliance form shall constitute Dell’s invoice to Licensor, and the MDF reimbursement shall be payable to Dell thirty (30) days following the date the Proof of Compliance was originally submitted by Dell. In the event expenses are incurred by Licensor, which are to be reimbursed from the MDF fund, the above process shall apply with the parties’ roles reversed.

iv. The MDF is provided at the sole discretion of Licensor. Licensor reserves the right to cancel the MDF with ninety (90) days notice to Dell. Licensor reserves the right, upon request, to audit the reimbursement process and/or the expenses submitted for reimbursement.

3.  Any and all Pricing Supplements to the Agreement are hereby replaced in their entirety with the attached Exhibit A to this Addendum. Dell’s cost for the products and skus listed in Exhibit A (“OEM Cost”) shall be a minimum of [***] than the cost at which CommVault makes available the equivalent or comparable products and skus listed on the Dell Direct Supplier Agreement with CommVault, dated August 2, 2008, as such may be amended from time to time by the parties (“S&P Cost”), such that if at any time the difference between the S&P Cost and the OEM Cost is less than [***], the OEM Cost shall be immediately lowered to maintain this requirement.

No other changes or modification are intended by this Addendum. All other terms and conditions of the Agreement are in effect.

Any capitalized terms defined in this Addendum are specific to this Addendum only, and do not modify or change the meaning set forth in the Agreement. Unless expressly defined in this Addendum, the capitalized terms in this Addendum are as defined in the Agreement. The Agreement shall remain in full force and effect except as supplemented and amended herein.
