Re:  Revised Amended Note

Dear James:

Reference is hereby made to that certain Loan Restructuring Agreement, dated as of December 16, 2010 (the “Loan Restructuring Agreement”), by and between Broadcast International, Inc., a Utah corporation (the “Company”), and Castlerigg Master Investments Ltd., a fund advised by Sandell Asset Management Corp. (the “Lender”).  Capitalized terms used but not otherwise defined herein shall have the respective meanings ascribed to them in the Loan Restructuring Agreement.  

The Company and the Lender hereby acknowledge and agree as follows:

1.

The form of Amended Note attached as Exhibit A to the Loan Restructuring Agreement is hereby deleted in its entirety and replaced with the form of Amended Note attached as Annex I hereto (the “Revised Amended Note”).  For the avoidance of doubt, all references to the “Amended Note” in the Transaction Documents shall refer to the Revised Amended Note.

2.

Notwithstanding Section 3.3(s) of the Loan Restructuring Agreement, the Company shall not be required to deliver an escrow agreement to the Lender, provided that, on the Closing Date, the Company (a) delivers an executed copy of the Revised Amended Note to the Lender and (b) prepays an amount equal to the aggregate amount of Interest (as defined in the Revised Amended Note) due and payable under the Revised Amended Note from the Issuance Date (as defined in the Revised Amended Note) through December 31, 2011 in accordance with the Revised Amended Note.

3.

Notwithstanding anything to the contrary contained in the Loan Restructuring Agreement or any other Transaction Document, at the Closing, the Company shall pay to the Lender, in lieu of delivery of the Shares and the Warrants pursuant to Section 2.2 of the Loan Restructuring Agreement, a one-time cash payment of $2,750,000 by wire transfer of immediately available funds to a bank account designated by the Lender.  All references to the Excess Shares, Full Issuance Shares, the Partial Issuance Shares, the Shares, the Warrant Shares and the Warrants (collectively, the “Shares and Warrants”), and all provisions relating solely to the Shares and Warrants in any Transaction Document, shall have no force or effect provided such cash payment is made at Closing..  For purposes of clarification, the foregoing shall have no effect on the Company’s obligations with respect to the Conversion Shares set forth in the Transaction Documents, which shall remain in full force and effect.

4.

In addition to the indemnification obligations of the Company pursuant to Section 8.3 of the Loan Restructuring Agreement, the Company shall defend, protect, indemnify and hold harmless the Indemnitees from and against any and all Indemnified Liabilities, incurred by any Indemnitee as a result of, or arising out of, or relating to the failure of Interact Devices, Inc. to be in good standing in such entity’s jurisdiction of formation.  To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable Requirements of Law.

5.
