such rights or remedies by the Holder would result in a default or acceleration

under any material agreement or instrument with a third party unaffiliated with

Accordingly, any delay in any cash payment under this Note (other than
in connection with a Change of Control) resulting from the restrictions
contained in this Article 4 shall not result in any breach or default under

the Note by exchange of its Common Stock if and to the extent that payment in

Holder execute and deliver to such creditor(s) other instruments, documents or
