prospectus, provided that any lock-up securities received upon such exercise, vesting or settlement would be subject to restrictions similar to those in the immediately preceding paragraph; (c) the
conversion, exchange or reclassification of outstanding equity securities into shares of our common stock or warrants to acquire shares of our common stock, provided that any such shares of our common stock or warrants received upon such conversion
would be subject to restrictions similar to those in the immediately preceding paragraph; and (d) the establishment by lock-up parties of trading plans pursuant to Rule
10b5-1 under the Exchange Act for the transfer of shares of the lock-up securities, provided that (1) such plans do not provide for the transfer of lock-up securities during the restricted period, and (2) any required public announcement or filing under the Exchange Act made by any person regarding the establishment of such plan during the restricted
period shall include a statement that the undersigned is not permitted to transfer, sell or otherwise dispose of securities under such plan during the restricted period in contravention of restrictions similar to those in the immediately preceding
paragraph and no public filing, report or announcement by any party shall be made voluntarily in connection with such trading plan.

J.P. Morgan Securities LLC, in
its sole discretion, may release the securities subject to any of the lock-up agreements with the underwriters described above, in whole or in part at any time.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act.

We have applied to have our Class A common stock approved for listing on the Nasdaq Global Select Market under the trading symbol “BLLN,” and this
offering is contingent upon obtaining such approval.

In connection with this offering, the underwriters may engage in stabilizing transactions, which involves
making bids for, purchasing and selling shares of Class A common stock in the open market for the purpose of preventing or retarding a decline in the market price of the Class A common stock while this offering is in progress. These
stabilizing transactions may include making short sales of Class A common stock, which involves the sale by the underwriters of a greater number of shares of Class A common stock than they are required to purchase in this offering, and
purchasing shares of Class A common stock on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option to
purchase additional shares referred to above
