Wow, you really have it wrong. TCA is the lender. It is not "IHSI or the Credit Parties", so it has nothing to do with the first paragraph.
As for the second, note that "such right shall not be available until such time as all Obligations in connection with the Credit Agreement, the Revolving Note, the Fee Note and any other Loan Document executed in connection therewith are completely and fully satisfied". Since IHSI hasn't paid of the first $635k, they have no right.
When you think "there can't be that many people falling for this", remember the Bernie Madoff story and recall that over $50 BILLION of smart money fell for a great story.
