Can I purchase shares through my brokerage account (e.g. ameritrade, e*trade, merrill lynch, charles schwab, scottrade, etc.)? If you have check-writing privileges on your account, you can purchase Zion stock by completing the Subscription Agreement and attaching a check payable to "Zion Oil & Gas Escrow Account". If you do not have that privilege, then you will not be able to purchase Zion stock in the IPO through your brokerage account as you would for a stock already listed on the exchanges. At $14 million, our IPO is relatively small, so the larger brokerage houses do not consider it cost-effective to become listed selling brokers. After the IPO has it's initial closing, then you may purchase through your broker in the open market at whatever the open market price might be.
