     Section 5.22(b) would be amended by deleting the figure “$230,000,000” and replacing same with “$200,000,000”.

     Please confirm that the foregoing is in accordance with your understanding by signing and returning to us a copy of this letter at your earliest convenience. These amendments will become effective upon our receipt of executed copies of this letter by all the parties hereto.
