Zach,
I have attached the adequacy response materials for TR -111. I'm waiting on a signature for the cover letter, which I
should have later today. I wanted to get these items in front of you as soon as I could. I will forward you the entire
package again via email once I receive a cover letter, and I will be putting a hard copy to you overnight via FedEx.

receive it. Let me know if you have questions.
