Explanation of Responses:
1. On July 11, 2011, Chesapeake NG Ventures Corporation ("Chesapeake"), an indirect wholly owned subsidiary of Chesapeake Energy Corporation, entered into a Loan Agreement (the "Agreement") with Clean Energy Fuels Corp. (the "Company"), whereby Chesapeake agreed to purchase from the Company up to $150 million aggregate principal amount of debt securities pursuant to the issuance of three convertible promissory notes (the "Notes"), each having a principal amount of $50 million. On June 14, 2013, Chesapeake sold the two Notes that were issued on July 11, 2011 and July 10, 2012, respectively (the "Initial Notes"), and transferred its obligation to purchase, on June 28, 2013, the third Note (the "Third Note"), for an aggregate purchase price of $85 million, plus accrued and unpaid interest (the "Sale Transaction").
2. The Notes are convertible into Common Stock of the Company ("Common Stock") at the holder's option upon issuance. As a result of the Sale Transaction, Chesapeake disposed of the right to acquire a total of (i) 6,329,112 shares of Common Stock that may be issued upon conversion of the Initial Notes, and (ii) 3,164,556 shares of Common Stock that may be issued upon conversion of the Third Note.
3. Subject to certain restrictions the Company can force conversion of a Note into Common Stock if, following the second anniversary of the issuance of the Note, the Common Stock shares trade at a 40% premium to the conversion price, as defined in the Agreement, for at least twenty trading days in any consecutive thirty trading day period. The entire principal balance of each Note is due and payable seven years following its issuance, and the Company may repay the Notes in Common Stock or cash.
