THIRD TO AGREEMENT AND PLAN OF MERGER (this “Amendment”) is made as of August 26, 2013, by and among Broadcast International,
Inc., a Utah corporation (“Parent”), Alta Acquisition Corporation, a Nevada corporation (“Merger Sub”)
and AllDigital Holdings, Inc., a Nevada corporation (the “Company”) with respect to the Agreement and Plan of Merger
dated January 6, 2013 among Parent, Merger Sub and the Company (including all amendments, the “Merger Agreement”),
as previously amended by the First Amendment to Agreement and Plan of Merger dated April 10, 2013 (the “First Amendment”)
and the Second Amendment to Agreement and Plan of Merger dated June 27, 2013 (the “Second Amendment”).

 

W I T N E S S E T H:

 

WHEREAS, the parties to the Merger Agreement
desire to exclude certain convertible notes from the calculation of the exchange ratio in the Merger, add or alter certain conditions
to closing and eliminate a discretionary termination right, all as provided herein;

 

NOW, THEREFORE, in consideration of the foregoing
premises and the representations, warranties, covenants and agreements set forth herein, as well as other good and valuable consideration
set forth herein and in the Merger Agreement, the receipt and sufficiency of which are hereby acknowledged and accepted, and intending
to be legally bound hereby, Parent, Merger Sub and the Company hereby agree as follows:

 

	1.		Defined Terms. Capitalized terms used but not
defined herein shall have the meanings ascribed to them under the Merger Agreement.

 

	2.		Amendments to Merger Agreement.

 

	a.		Add Definition of Combined Convertible Notes.
The following definition shall be added to Exhibit A:

 

“Combined
Convertible Notes” shall mean Convertible Promissory Notes issued by the Company, and countersigned by Parent, that
are convertible (i) into Company Common Stock if the Merger does not close by November 30, 2013 or this Agreement is terminated,
and (ii) into Parent Common Stock if the Merger closes by November 30, 2013.

 

	b.		Amendment to Definitions of Parent and Company Fully
Diluted Common Stock. The definition of “Parent Fully Diluted Common Stock” and the definition of “Company

and other rights or securities of any kind exercisable for, convertible into or exchangeable for Parent Common Stock (whether
or not such rights or securities are vested, conditioned, contingent or otherwise limited as to exercisability in any way). For
purposes of clarity, the Parent Fully Diluted Common Stock shall not include the Per Share Merger Consideration, the Combined
Convertible Notes or any shares of Parent Common Stock issuable upon conversion of the Combined Convertible Notes.

 

    	 

    	 

    

 

“Company
Fully Diluted Common Stock” means a number of shares equal to the sum of (a) the issued and outstanding shares of Company
Common Stock as of the applicable date, and (ii) the number of shares of Company Common Stock that are issuable upon the exercise,
conversion or exchange of any Company Options, Company Warrants and other rights or securities of any kind exercisable for, convertible
into or exchangeable for Company Common Stock (whether or not such rights or securities are vested, conditioned, contingent or
otherwise limited as to exercisability in any way) other than the shares of Company Common Stock issuable upon the exercise of
Fully Offset Options. Notwithstanding the foregoing, Company Fully Diluted Common Stock shall not include the Combined Convertible
Notes or any shares of Company Common Stock issuable upon conversion of the Combined Convertible Notes.

 

	c.		Amendment of Committed Capital Requirement. Section
7.20 to the Merger Agreement, which was added by the Second Amendment, is hereby amended and restated as follows:

 

7.20Capital
Commitment. There shall be in place valid, binding and irrevocable subscription agreements or other commitments with respect
to the purchase from Parent immediately following Closing of an amount of Parent Common Stock equal to no less than the amount,
if any, by which $1.5 million exceeds the principal amount of the Combined Convertible Notes (and no more than $3.5 million) on
terms and conditions approved in writing by the Company in its discretion with investors approved by the Company in writing on
a subscription-by-subscription basis. No counterparty to any such subscription agreement or commitment shall be in default or
shall have asserted that Parent is in default or that any conditions to the counterparty’s obligation to close such financing
is not satisfied or will not be satisfied upon the Closing.

 

	d.		Additional Condition to Closing. A new Section
7.21 is hereby added to the Merger Agreement, which shall read as follows:

 

7.21Resolution
of IP Ownership Issue. No one but Parent shall have any ownership interest in any Intellectual Property or Intellectual Property
Rights at any time owned or supplied by Parent, as determined by the Company in its reasonable discretion.

Conversion to AllDigital Common Stock. In the event that the Merger Termination Date occurs prior to the Merger Closing Date,
then the outstanding principal amount of and all accrued interest under this Note shall automatically convert into that number
of shares of the AllDigital Common Stock as is determined by dividing such principal amount, plus accrued interest, by the AllDigital
Per Share Purchase Price. Holder also agrees to deliver the original of this Note (or a notice to the effect that the original
Note has been lost, stolen or destroyed and an agreement acceptable to AllDigital whereby the holder agrees to indemnify AllDigital
from any loss incurred by it in connection with this Note) promptly following receipt of notification of occurrence of the Merger
Termination Date; provided, however, that upon the Merger Termination Date, this Note shall be deemed converted and of
no further force and effect, whether or not it is delivered for cancellation as set forth in this sentence.

 

    	N-2

    	 

    

 

(b) Automatic
Conversion to Broadcast Common Stock. In the event that the Merger Closing Date occurs by November 30, 2013, then AllDigital
shall be a wholly-owned subsidiary of Broadcast and the outstanding principal amount of and all accrued interest under this Note
shall automatically convert into that number of shares of the Broadcast Common Stock as is determined by dividing such principal
amount, plus accrued interest, by the Broadcast Per Share Purchase Price. Holder also agrees to deliver the original of this Note
(or a notice to the effect that the original Note has been lost, stolen or destroyed and an agreement acceptable to AllDigital
and Broadcast whereby the holder agrees to indemnify AllDigital and Broadcast from any loss incurred by it in connection with
this Note) promptly following receipt of notification of occurrence of the Merger Closing Date; provided, however, that
upon the Merger Closing Date, this Note shall be deemed converted and of no further force and effect, whether or not it is delivered
for cancellation as set forth in this sentence.

 

(c) Fractional
Shares; Interest; Effect of Conversion. No fractional shares shall be issued upon conversion of this Note. In lieu of AllDigital
or Broadcast issuing any fractional shares to Holder upon the conversion of this Note, AllDigital or Broadcast, as applicable,
shall pay to Holder an amount equal to the product obtained by multiplying the conversion price by the fraction of a share not
issued pursuant to the previous sentence. 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.

 

7. Successors
and Assigns. Subject to the restrictions on transfer described in Sections 9 and 10 below, the rights and
obligations of AllDigital, Broadcast and Holder shall be binding upon and benefit the successors, assigns, heirs, administrators
and transferees of the parties.

 

8. Waiver
and Amendment. Any provision of this Note may be amended, waived or modified upon the written consent of AllDigital and
the holders of a Seventy-five Percent (75%) Majority in Interest.

9. Transfer
of this Note or Securities Issuable on Conversion Hereof. 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.

on the unpaid principal balance hereof at a rate per annum equal to the rate otherwise applicable hereunder plus five percent
(5%). 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.
