Here's the letter I sent to Calphalon with my last replacement pan in 2010. Check the address on their site to confirm it is still valid. I'm not sure which one they replaced it with, but I like it better than the original pan

Hello,
I am returning a Calphalon nonstick 10” frypan for replacement. We got this as part of a set, and the nonstick coating is failing. We have always cared for this according to the instructions, and only handwash it and we use Calphalon nylon utensils with these for cooking.
Since these were the premium Calphalon nonstick products at the time, we would request that it be replaced with Calphalon One or Unison.
Best regards,
Chris Young
