Dear Paul,

Thank you for writing a letter of reference to Peter Paulson at Interfinance Corp. I spoke with Mr. Paulson yesterday and he says I am a strong candidate for the financial analyst position! That certainly is good news. I'll let you know how it turns out.

Once again, thank you for providing a good reference for me. If there's anything you need, please let me know.

Sincerely,

(Signature)

David
