LLC, BofA Securities, Inc. and Morgan Stanley & Co. LLC, during the period beginning from the date of this Lock-Up Agreement and continuing to and including the date 180 days after the date set forth on the final prospectus used to sell the Shares (the “Lock-Up Period”), the undersigned shall not, and shall not cause or direct any of its affiliates to, (i) offer, sell, contract to sell, pledge, grant any option to purchase, lend or otherwise dispose of any shares of Common Stock of the Company or units of Zevia LLC, or any options or warrants to purchase any shares of Common Stock of the Company or units of Zevia LLC, or any securities convertible into, exchangeable for or that represent the right to receive shares of Common Stock of the Company or units of Zevia LLC (such options, warrants or other securities, collectively, “Derivative Instruments”), including without limitation any such shares or Derivative Instruments now owned or hereafter acquired by the undersigned (collectively, the “Restricted Securities”), (ii) engage in any hedging or other transaction or arrangement (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward, swap
