First of all,
Please do your homework first, ask questions second.
This is, at least, the tenth explanation concerning the original MTA agreement, the original TDA agreement and the original TTA agreement- 3 agreements, the second and third being subsidiary to the first.
1) The MTA agreement is IN PERPETUITY.....FOREVER and the price was and remains $20 million. PERIOD. Alreadly paid.
2) The TDA agreement expired in Feb 2012 and was extended 2 years to 2014.
None of this extension is subject to any future revenues. PERIOD.
3) The TTA has already expired and is HISTORY.
You may thank me in advance. No further answers to your question remain.
