Upon conversion of this Note in full and the payment of any amounts specified in this Section 7(c), each of AllDigital and Broadcast shall be forever released from all its obligations and liabilities under this Note.

With respect to any offer, sale or other disposition of this Note or securities into which such Note may be converted, Holder will give written notice to AllDigital prior thereto, describing briefly the manner thereof, together with a written opinion of Holder’s counsel, or other evidence if reasonably satisfactory to AllDigital, to the effect that such offer, sale or other distribution may be effected without registration or qualification under the Securities Act. Upon receiving such written notice and reasonably satisfactory opinion, if so requested, or other evidence, AllDigital, as promptly as practicable, shall notify Holder that Holder may sell or otherwise dispose of this Note or such securities, all in accordance with the terms of the notice delivered to AllDigital. If a determination has been made pursuant to this Section 9 that the opinion of counsel for Holder, or other evidence, is not reasonably satisfactory to AllDigital, AllDigital shall so notify Holder promptly after such determination has been made. Each Note thus transferred and each certificate representing the securities thus transferred shall bear a legend as to the applicable restrictions on transferability in order to ensure compliance with the Securities Act, unless in the opinion of counsel for AllDigital such legend is not required in order to ensure compliance with the Securities Act. AllDigital or Broadcast, as applicable, may issue stop transfer instructions to its transfer agent in connection with such restrictions. Subject to the foregoing, transfers of this Note shall be registered upon registration books maintained for such purpose by or on behalf of AllDigital. Prior to presentation of this Note for registration of transfer, AllDigital shall treat the registered holder hereof as the owner and holder of this Note for the purpose of receiving all payments of principal and interest hereon and for all other purposes whatsoever, whether or not this Note shall be overdue and AllDigital shall not be affected by notice to the contrary.

10. Assignment by AllDigital or Broadcast. Neither this Note nor any of the rights, interests or obligations hereunder may be assigned, other than by operation of law, in whole or in part, by AllDigital or Broadcast without the prior written consent of the holders of a Seventy-five Percent (75%) Majority in Interest or by Holder without the prior written consent of AllDigital.

In the event any interest is paid on this Note which is deemed to be in excess of the then legal maximum rate, then that portion of the interest payment representing an amount in excess of the then legal maximum rate shall be deemed a payment of principal and applied against the principal of this Note.

14. Waivers. AllDigital hereby waives notice of default, presentment or demand for payment, protest or notice of nonpayment or dishonor and all other notices or demands relative to this instrument.
