Explanation of Responses:

1. On November 10, 2017, the reporting person entered into a forward sale contract with an unaffiliated third party buyer. This contract obligates the reporting person to deliver to the buyer up to 300,000 shares of EXR common stock (or, at the reporting person's election, an equivalent amount of cash based on the market price of EXR common stock at that time) on the maturity date of the contract (November 8, 2018). In exchange for assuming this obligation, the reporting person will receive a cash payment of $21,761,337. The reporting person pledged 300,000 shares of EXR common stock (the "New Pledged Shares") to secure his obligations under the contract, and retained voting and dividend rights in the New Pledged Shares during the term of the pledge. (continued in footnote 2)

2. The number of shares of EXR common stock to be delivered to the buyer on the maturity date would be determined as follows: (a) if the volume weighted average price of EXR common stock on November 8, 2018 (the "Settlement Price") is less than or equal to $77.0977 ( the "Floor Level"), the reporting person will deliver to the buyer all of the New Pledged Shares; (b) if the Settlement Price is between the Floor Level and $94.2305 (the "Cap Level"), the reporting person will deliver to the buyer a number of shares of EXR common stock equal to 300,000 shares multiplied by a fraction, the numerator of which is the Floor Level and the denominator of which is the Settlement Price; (continued in footnote3)

3. and (c) if the Settlement Price is greater than the Cap Level, the reporting person will deliver to the buyer the number of shares of EXR common stock equal to 300,000 shares multiplied by a fraction, the numerator of which is the Floor Level plus the excess of the Settlement Price over the Cap Level, and the denominator of which is the Settlement Price.
