ADDENDUM NINE
TO THE

BETWEEN
DELL PRODUCTS, LP
AND
COMMVAULT SYSTEMS, INC.

This Addendum Nine (“Addendum”) to the Software License Agreement dated December 17, 2003 (the “Agreement”), is entered into by and between Dell Global BV (Singapore Branch) (hereinafter “Dell”), and CommVault Systems, Inc., (hereinafter “CommVault”) a Delaware corporation having a principal place of business at 2 Crescent Place, Oceanport, New Jersey 07757 (hereinafter “Licensor”) and is effective as of the 1st day of September, 2008 (the “Effective Date”).

RECITALS

WHEREAS, CommVault and Dell entered into the Agreement through which CommVault granted Dell various rights to distribute certain CommVault software products;

WHEREAS, CommVault and Dell wish to amend the Agreement and replace all Pricing Supplements, as set forth in Addendum #7 dated January 28, 2008 and also wish to add rebate and marketing development fund (“MDF”) provisions.

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:

     1. Quarterly Rebate.

          For Licensed Products distributed by Dell, Dell shall earn a rebate equal to [***] (“Rebate Percentage”) of the aggregate quarterly software royalties paid by Dell, as reported on the royalty report. Rebate shall be payable to Dell within forty-five (45) days after the receipt of Dell’s quarterly royalty payments to Licensor. For clarification, Volume Purchase Agreement (“VPA”) and Enterprise License Agreement (“ELA”) transactions are excluded from the definition of Licensed Products for the purposes of the Rebate Percentage only.

          During the term of the Agreement, Licensor agrees that Dell shall have the right effective as of the first day of Dell’s fiscal quarter following the Effective Date of this Addendum, and upon sixty (60) days prior written notice to Licensor, to adjust the Rebate Percentage, provided that in no event shall the Rebate Percentage exceed [***]. Any adjustment to the Rebate Percentage shall be offset by a corresponding percentage increase or decrease in the applicable Dell SW Cost (Column 1 of Exhibit A).

     2. Quarterly MDF

          For Licensed Products distributed by Dell, Dell shall earn MDF equal to [***] (“MDF Percentage”) of the aggregate quarterly software royalties paid by Dell, as reported on the royalty report. For clarification, VPA and ELA transaction are excluded from the definition of Licensed Products for the purposes of the MDF Percentage only.

          2.1 Terms and conditions of MDF

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.

     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.

IN WITNESS WHEREOF, the parties have executed this Addendum by their duly authorized representatives effective as of the date first set forth above.
