Also in connection with the Business Combination, (i) Mobius changed its name to "Sintana Energy Inc." (the "Name Change"); (ii) each outstanding share purchase warrant of Sintana (each, a "Sintana Warrant") became exercisable to acquire Mobius Shares in lieu of Sintana Shares subject to adjustment in number and exercise price to give effect to the Exchange Ratio; and (iii) each stock option of Sintana was exchanged for an equivalent stock option of Mobius, subject to adjustment in number and exercise price to give effect to the Exchange Ratio.

Each stock option of Mobius outstanding immediately prior to the effective date of the Business Combination vested and will remain outstanding until the earlier of: (A) the original expiration date thereof; and (B) the date that is the later of: (I) December 31, 2016, and (II) the latest date provided for pursuant to the Mobius stock option plan.

The shares of the combined company after giving effect to the Business Combination and the Name Change to Sintana Energy Inc. are scheduled to commence trading on the TSX Venture Exchange ("TSXV") under the symbol "SEI" effective as of the market open on Monday, August 10, 2015.
