Explanation of Responses:

1. Shares purchased pursuant to the Employee Stock Purchase Plan.

2. The options vest at 25% at year one and 6.25% quarterly thereafter beginning on August 3, 2011.

3. Each restricted stock unit represents a contingent right to receive one share of Dionex Corporation common stock.

4. The restricted stock units vest in five equal annual installments beginning August 3, 2011. Delivery of one share of Common Stock for each Restricted Stock Unit that vests shall occur on the date that is the earlier of (i) five years after August 3, 2010 and (ii) the termination of continuous service to Dionex Corporation by the officer provided that delivery may be delayed as provided in the Stock Unit Award Agreement.

5. Each Performance-based Restricted Stock Unit (RSU) represents the right to receive, following vesting, shares of common stock. The resulting number of shares of common stock acquired upon vesting of the Performance-based RSUs is contingent upon the achievement of pre-established performance metrics, as approved by the Company's Compensation Committee. If the performance target is not achieved then the number shares issued will be reduced prorate to a threshold of 50% of the targets under which no shares will vest. If the performance target is achieved then the number of shares listed above shall vest. If the performance target is exceeded then shares up to a maximum of 150% of the target grant listed above shall vest. Vesting for performance based RSUs occurs over a 4 year period with a cliff vest after 2 years at 50% (if target is met or exceeded) and 25% each year thereafter.

6. There is no expiration date
