Ginger, your description of your legal interest in the company is not entirely clear. You say you were promised founders' shares, which would normally mean you become the owner of stock and are an equity shareholder, but then you say you received options, which is not the same thing as receiving shares. Since you ask about the option strike price, it sounds like you in fact received options rather than founders' shares, so you are not an equity shareholder. You simply have the right to purchase stock and become an equity shareholder, if you choose to do so.
As for whether your options are priced correctly, normally an agreement to grant options would state the option price, or tie it to something that is fairly easily verifiable. So, for example, your deal agreement could say that you will receive options to purchase 1,000 shares a $0.05 per share. On the other hand, options are supposed to be priced at the strike price at the time of the actual grant, which is the time that the board agrees to have the options issued. So, if the company has increased in value in the ensuing two years since your deal, the strike price of the options would have increased between the time of your deal and the time the company finally issued the options.
The only way to know for sure is to ask the company to provide you documentation of the option strike price history, which is set by the board.
