 2 








 
net proceeds of one or more Capital Event(s) or (ii) Borrowers demonstrate that the Borrowing Base (without giving effect to the Note Advance) is in excess
of $65,000,000 (each an “Increase Condition”), then upon such event, Maximum Revolving Advance Amount shall mean Seventy Five Million Dollars ($75,000,000); provided further that, if Borrowers do not meet an Increase
Condition on or before May 1, 2005, then commencing on May 1, 2005 and at all times thereafter until Borrowers satisfy an Increase Condition, Maximum Revolving Advance Amount shall mean Sixty Five Million Dollars ($65,000,000). 
  
 (ii) The definitions “Note” and “Note

occurs and such net proceeds in excess of $12,000,000 but not more than $20,000,000 are applied prior to May 1, 2005, Borrowers may, so long as no Default or Event of Default has occurred or is continuing, elect to maintain the Note Advance at an

time not greater than such Lender’s Commitment Percentage of the Borrowing Base (as defined below) minus the undrawn or unreimbursed amount of outstanding Letters of Credit unless Borrowers have deposited with Agent cash collateral in
such amounts and in accordance with Section 3.2. For purposes hereof, “Borrowing Base” shall mean the lesser of (x) the Maximum Revolving Advance Amount or (y) the sum of:
