- Estimated solely for purposes of calculating the filing fee. This calculation is based on the offer to purchase all of the issued and outstanding shares of common stock, par value $0.001 per share (the "Shares"), of Dot Hill Systems Corp., at a purchase price of $9.75 per Share, without interest thereon, net to the seller in cash and subject to reduction for any applicable U.S. federal withholding, back-up withholding or other applicable tax withholdings. The underlying value of the transaction was calculated based on the sum of: (i) 62,397,539 issued and outstanding Shares (which includes 383,333 Shares subject to vesting or forfeiture or repurchase by Dot Hill Systems Corp.), multiplied by $9.75 per Share; (ii) 10,763,175 Shares underlying outstanding options (consisting of vested options to purchase 6,225,053 Shares and unvested options to purchase 4,538,122 Shares) with an exercise price that is less than $9.75 per Share, multiplied by $6.66 per Share (which is equal to the difference between $9.75 and $3.09, the weighted average exercise price of such options that have an exercise price that is less than $9.75 per Share); (iii) up to 68,000 Shares subject to vesting contingent upon specified performance criteria, multiplied by $9.75 per Share; (iv) 83,076 Shares estimated to be subject to outstanding rights under the 2014 Employee Stock Purchase Plan (the "ESPP") (assuming the closing price per Share as reported by the NASDAQ Global Market on the purchase date for the current offering period was equal to the offer price per Share, employee contributions continue until such purchase date at levels in place as of August 17, 2015 and the Merger (as defined below) is consummated prior to October 9, 2015), multiplied by $9.75 per Share; and (v) 1,602,489 Shares issuable pursuant to an outstanding warrant with an exercise price less than $9.75 per Share, multiplied by $7.35 per Share, which is the offer price per Share minus the exercise price of such warrant of $2.40 per Share.

- The filing fee, calculated in accordance with Rule 0-11 of the Securities Exchange Act of 1934, as amended, and Fee Rate Advisory #1 for fiscal year 2015, issued August 29, 2014, is calculated by multiplying the transaction valuation by 0.0001162.
