White, Fring, and Pinkman are partners in the operation of the A1A car wash. Without Fring's knowledge, White and Pinkman sold 10 percent of their interest in the business and its profits to Herzog and agreed that Herzog would be a partner of the business. Fring had not agreed to give White and Pinkman authority to make such an agreement. Is Herzog a partner in the A1A car wash business?
