Just got off the phone with Amex. I told them I wanted to add an additional cardmember and when they asked for the name, I gave them by name and simply said that I want a second card for business expenses. The CSR confirmed my info and seemed to have no problem with it. Told me that I should receive the second card in about 1-2 weeks. The best part is that I got a bonus 1000 starpoints for adding the additional card!
