The renewal of the limited warranty after the first year is at the option of the customer, but in any case, Unit failure does not relieve Power2Ship of its obligation to pay the monthly License Fees to WLI for that Unit. The first year limited warranty starts on the day of the activation of the Unit on a wireless network. As a distributor, Power2Ship should keep a minimum number of Units in stock for immediate replacement for its customers. 7.5.

Failure of the customer to pay Power2Ship, for whatever reason, does not affect the obligation of Power2Ship to pay its contractual obligations to WLI. 7.6. If an invoice is past due by more than 30 days, WLI may discontinue providing technical support to Power2Ship until the invoice is paid. If Power2Ship does not make payment of any amount due and payable hereunder within 60 days of the date of invoice, WLI (without prejudice to any other remedy) shall be entitled to interest on all past due amounts at the lower of eighteen percent (18%) per annum or the highest rate permitted by law, plus reimbursement of all costs incurred in collecting such amounts, including court costs and reasonable attorney fees. 8. LICENSED SOFTWARE ACCESS AND AUDIT 8.1. Should a dispute occur concerning the number of Units that Power2Ship has activated with its customer, WLI may designate an independent certified public accountant who may audit Power2Ship's books and records concerning sales of Units and of Licensed Software under this Agreement. Said examination shall be at WLI's sole cost and expense during normal
