I am a little unclear about the "$36,000's-worth". I assume that that is the face value of the 9,000 shares. So if $36k is the value of the underlying stock than the share price is $4. The same $4 a share that the stock was worth when your options were issued.
The new options were issued for $1 a share with a $4 stock price. Assuming that there was a buyer for the shares at the current price of $4 the options could be exercised today and be worth $27k.
$4 - $1 = $3 per share profit X 9,000 shares = $27,000.
Some valuation examples
Price Theirs Yours $4 $27k $0 $5 $36k $37.5k $6 $45k $75k $7 $54k $112.5k $10 $81k $225k
What the options are worth today is really a minor concern. You control substantially more shares than the people who have just been issued options. If the company succeeds you all walk away with a bunch of money. If it doesn't, well none of you are going to make anything from your options.
