Accordingly, Seagate Technology (US) Holdings, EVault and the Collateral Agent agree as follows:

SECTION 1.  Schedule II in the Second Lien U.S. Security Agreement is hereby supplemented by adding the Equity Interests identified on Schedule A to this Supplement

SECTION 3.  This Supplement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract.  This Supplement shall become effective when the Collateral Agent shall have received counterparts of this Supplement that, when taken together, bear the signatures of the New Pledgors and the Collateral Agent.  Delivery of an executed signature page to this Supplement by facsimile or Adobe .pdf transmission shall be as effective as delivery of a manually signed counterpart of this Supplement.
