(c) Costs and Expenses. Iridium further agrees to reimburse Motorola for all reasonable out-of-pocket costs and expenses (including, without limitation, the fees and expenses of legal counsel) in connection with any enforcement of Iridium's obligations under Section 1(a) (including, without limitation, any fees and expenses incurred in connection with any bankruptcy proceedings).
