Explanation of Responses:
1. Pursuant to the terms of the Plan of Merger Agreement by and between Maxim Integrated Products, Inc. and Volterra Semiconductor Corporation (the "Merger Agreement"), each share of Volterra common stock was validly tendered for $23.00 per share in cash, without interest, subject to any required witholding of taxes.
2. This amount reflects the amount of shares held by the Teuscher 2007 Trust following bonafide gift dispostions from the Teuscher 2007 Trust for a total amount of 113,026 shares on September 23, 2013.
3. Held by the Teuscher 2007 Trust, of which the reporting person is a co-trustee.
4. Pursuant to the terms of the Merger Agreement, each stock option that was outstanding, whether vested or unvested, with an exercise price per share less than the Offer Price as of the Effective Time (as defined in the Merger Agreement) was substituted with a Substitute Option (as defined in the Merger Agreement).
5. This Amendment is being filed to correct the number of shares reported.
6. Pursuant to the terms of the Merger Agreement, each restricted Stock Unit ("RSU") that was outstanding as of the Effective Time (as defined in the Merger Agreement) was substituted with a Substitute RSU (as defined in the Merger Agreement).
