Roth Ira conversion recharacterization still possible?

[Guest BrianR]

In 1998, I converted my traditional IRA to a RothIRA. The value at that time was $400000 and I elected the 5 year option. I subsequently filed and paid the taxes due on my 1998 and 1999 returns..still have to file the rest. The value of my investments has now dropped to $125000 and I dont have the cash to pay the remaining taxes. What are my options here? Thanks.
