This Waiver and Amendment Agreement (this "Agreement") is entered into as of
March 16, 2006, by and among BROADCAST INTERNATIONAL, INC., a Utah corporation
(the "Company"), and the PURCHASERS named on the signature pages to this
Agreement (each, a "Purchaser" and collectively, the "Purchasers"), with
reference to the following facts:

      A.   The Company and the Purchasers are parties to, among others, the
following documents:

            1.   Securities Purchase Agreement dated May 16, 2005 (the
                 "Purchase Agreement");

            2.   6% Senior Secured Convertible Notes Due 2008, each dated May
                 16, 2005, executed by the Company in favor of the Purchasers
                (the "Notes");

            3.   Warrants (both Series A and Series B) for the Purchase of
                 Shares of Common Stock, each dated May 16, 2005, executed by
                 the Company in favor of the Purchasers (the "Warrants");

            4.   Registration Rights Agreement dated May 16, 2005 (the
                 "Registration Rights Agreement"); and

            5.   Forbearance Agreement dated November 30, 2005, (the
                 "Forbearance Agreement").

The above-referenced documents, all other documents executed in connection
therewith and all other agreements between or among the Company and one or
more of the Purchasers are hereinafter collectively referred to as the
"Operative Documents".

      B.   The Company is currently in default of the Forbearance Agreement by
failing to pay when due the Forbearance Fee.

      C.   The Company has requested that the Purchasers (i) terminate the
Forbearance Agreement, and (ii) waive all currently existing defaults under
the Operative Documents, and the Purchasers have agreed to do so, provided
that the Company enters into this Agreement.

      NOW, THEREFORE, for good and valuable consideration, the parties agree
as follows:

      1.   Defined Terms.  Capitalized terms not otherwise defined herein
shall have the same meanings as set forth in the Operative Documents.

      2.   Termination of Forbearance Agreement. The Company and the
Purchasers hereby agree that the Forbearance Agreement shall be terminated and
no longer of any force or effect, and that, upon such termination, no party
thereto shall have any further rights, duties or obligations thereunder.
Without limiting the generality of the foregoing, from and after such
termination of the Forbearance Agreement, no Purchaser shall have any further
right to receive the Forbearance Fee or to receive any Liquidated Damages due
to such Purchaser under the Registration Rights Agreement as of the date of
such termination.

                                1

<PAGE>

      3.    Waiver.  The Purchasers hereby forever waive any and all defaults,
which have occurred prior to the date hereof, under the Operative Documents.
The Purchasers, however, specifically do not waive any future defaults under
the Operative Documents or this Agreement which may occur from and after the
date of this Agreement, including, without limitation, any defaults occurring
under the Registration Rights Agreement from and after the date of this
Agreement that arise or result from the Company's attempt to amend its
currently effective SB-2 registration statement, as contemplated by Section 7
below.

      4.    Amendments to the Purchase Agreement. The Purchase Agreement is
hereby amended as follows:

            (a)   The definition of "Transaction Documents" set forth in
                  Section 2.1(b) of the Purchase Agreement is amended to
                  specifically include this Agreement.

            (b)   Section 3.12 of the Purchase Agreement is deleted in its
                  entirety.

            (c)   Section 3.15(c) of the Purchase Agreement is deleted in its
                  entirety.

      5.    Amendments to the Notes.  Each Note is hereby amended as follows:

            (a)   The definition of "Conversion Price" set forth in Section 1
                  of each Note is hereby amended in its entirety to read as
                  follows:

                  " "Conversion Price" means $1.50, subject to adjustment as
                     set forth herein."

            (b)   Section 4(a) of each Note is hereby amended by adding a new
                  subsection (xi) thereto (which new subsection shall be an
                  additional "Event of Default" under each Note), which new
                  subsection (xi) shall read in its entirety as follows:

                  "(xi) if the Company fails to raise and receive, by
                   September 30, 2006, at least $3,000,000 in cash net
                   proceeds through one or more private or public placements
                   of its securities."

      6.    Amendment to the Warrants.  Each Warrant (Series A and Series B)
is hereby amended by changing the "Exercise Price" to $2.00.

      7.    Registration Rights. The Company shall include by means of a
prospectus supplement pursuant to Rule 424(b)(3) of the Securities Act the
additional shares of Common Stock issuable upon conversion of the Notes as a
result of the amendment to the Notes effected by Section 5(a) above in its
currently effective SB-2 registration statement by allocating additional
registered shares of Common Stock to the Purchasers for purposes of resale
thereunder.

      8.    Release.

            (a)   The Company acknowledges that the Purchasers would not enter
into this Agreement without the Company's assurance that the Company has no
claims against any Purchaser or any of the Purchasers' partners, affiliates,
employees or agents.  Except for the obligations arising hereafter under this
Agreement and the Operative Documents, the Company releases each Purchaser,
any person or entity that has obtained any interest from any Purchaser under
the Operative Documents and each Purchaser's and such entity's partners,
affiliates, officers, directors, employees and agents from any known or
unknown claims which the

                                2

<PAGE>

Company now has against any Purchaser of any nature, including any claims that
the Company, its successors, counsel, and advisors may in the future discover
they would have now had if they had known facts not now known to them, whether
founded in contract, in tort or pursuant to any other theory of liability,
including but not limited to any claims arising out of or related to the
Operative Documents or the transactions contemplated thereby.

            (b)   The provisions, waivers and releases set forth in this
section are binding upon the Company and the Company's shareholders, agents,
employees, assigns and successors in interest.  The provisions, waivers and
releases of this section shall inure to the benefit of the Purchasers and
their respective partners, affiliates, agents, employees, officers, directors,
assigns and successors in interest.

            (c)   The Company warrants and represents that the Company is the
sole and lawful owner of all right, title and interest in and to all of the
claims released hereby and the Company has not heretofore voluntarily, by
operation of law or otherwise, assigned or transferred or purported to assign
or transfer to any person any such claim or any portion thereof.  The Company
shall indemnify and hold harmless each Purchaser from and against any claim,
demand, damage, debt, liability (including payment of attorneys' fees and
costs actually incurred whether or not litigation is commenced) based on or
arising out of any assignment or transfer.

            (d)   The provisions of this Section 8 shall survive payment in
full of the amounts owed by the Company to the Purchasers, full performance of
all the terms of this Agreement and the Operative Documents, and/or any
Purchaser's actions to exercise any remedy available hereunder, under the
Operative Documents or otherwise.

      9.    Termination and Rescission. If for any reason the Company is
unable to accomplish the reallocation described in Section 7 above by March
31, 2006 (with the understanding that such SB-2 registration statement, as so
amended, will be effective no later than March 31, 2006), then, unless all of
the parties hereto agree in writing to the contrary, this Agreement shall be
automatically terminated and rescinded and no longer of any force or effect,
and that, upon such termination and rescission, no party hereto shall have any
further rights, duties or obligations hereunder (other than the Company's
obligations under Section 13(j), which shall survive any such termination and
rescission). Without limiting the generality of the foregoing, upon any such
termination and rescission of this Agreement, the Forbearance Agreement shall
be reinstated in full, and any and all waivers, releases and amendments
purported to be made hereby (including, without limitation, those purported to
be made under Sections 3, 4, 5, 6 and 8) shall be rescinded in full, as if
this Agreement had never been executed in the first instance.

      10.   Further Assurances.  The Company will take such other actions as
the Purchasers may reasonably request from time to time to accomplish the
objectives of this Agreement.

      11.   Consultation of Counsel.  The Company acknowledges that the
Company has had the opportunity to be represented by legal counsel of its own
choice throughout all of the negotiations that preceded the execution of this
Agreement.  The Company has executed this Agreement after reviewing and
understanding each provision of this Agreement and without reliance upon any
promise or representation of any person or persons acting for or on behalf of
any Purchaser.  The Company further acknowledges that the Company and its
counsel have had adequate opportunity to make whatever investigation or
inquiry they may deem necessary or desirable in connection with the subject
matter of this Agreement prior to the execution hereof and the delivery and
acceptance of the consideration described herein.

                                3

<PAGE>

      12.   Notices.  Unless otherwise provided in this Agreement, all notices
or demands by any party relating to this Agreement or any other agreement
entered into in connection herewith shall be in writing and shall be
personally delivered or sent by a recognized overnight delivery service,
certified mail, postage prepaid, return receipt requested, or by facsimile to
the Company or to any Purchaser, as the case may be, at its address set forth
in the Purchase Agreement.

      13.   Miscellaneous.

            (a)   Successors and Assigns.  This Agreement shall be binding
upon and shall inure to the benefit of the Company and the Purchasers and
their respective successors and assigns; provided, however, that the foregoing
shall not authorize any assignment by the Company of its rights or duties
hereunder.

            (b)   Integration.  This Agreement and any documents executed in
connection herewith or pursuant hereto contain the entire agreement between
the parties with respect to the subject matter hereof and supersede all prior
agreements, understandings, offers and negotiations, oral or written, with
respect thereto and no extrinsic evidence whatsoever may be introduced in any
judicial or arbitration proceeding, if any, involving this Agreement.

            (c)   Effect of this Agreement.  This Agreement does not amend,
impair, alter, waive, annul, vary or affect any provision, acknowledgement,
representation, condition, covenant, right, security interest, lien or remedy
contained in the Operative Documents or in any other instrument or agreement
at any time executed by the Company in favor of any Purchaser, except as
expressly provided in this Agreement.  The Company and the Purchasers intend
that the terms and provisions contained in the other Operative Documents shall
continue in full force and effect, subject only to the terms of this
Agreement.  In the event that the terms of this Agreement conflict with those
of the Operative Documents, the terms of this Agreement shall govern.

            (d)   Course of Dealing; Waivers.  No course of dealing on the
part of the any Purchaser or its partners, nor any failure or delay in the
exercise of any right by any Purchaser, shall operate as a waiver thereof, and
any single or partial exercise of any such right shall not preclude any later
exercise of any such right.  Any Purchaser's failure at any time to require
strict performance by the Company of any provision shall not affect any right
of such Purchaser thereafter to demand strict compliance and performance.  Any
suspension or waiver of a right must be in writing signed by a general partner
of each Purchaser.

            (e)   Time is of the Essence.  Time is of the essence as to each
and every term and provision of this Agreement and the other Operative
Documents.

            (f)   Counterparts.  This Agreement may be signed in counterparts
and all of such counterparts when properly executed by the appropriate parties
thereto together shall serve as a fully executed document, binding upon the
parties.

            (g)   Legal Effect.  If any provision of this Agreement conflicts
with applicable law, such provision shall be deemed severed from this
Agreement, and the balance of this Agreement shall remain in full force and
effect.

            (h)   Governing Law; Jurisdiction.  This Agreement shall be
governed by, and construed in accordance with, the laws of the State of Texas
without regard to principles of conflicts of laws.  The parties hereby agree
that all actions or proceedings arising directly or indirectly from or in
connection with this Agreement shall be litigated exclusively in the United

                                4

<PAGE>

States District Court for the Northern District of Texas located in Dallas
County, Dallas, Texas. The parties consent and submit to the jurisdiction and
venue of the foregoing court and consent that any process or notice of motion
or other application to said court or a judge thereof may be served inside or
outside the State of Texas or the Northern District of Texas (but with respect
to any party hereto, such consent shall not be deemed a general consent to
jurisdiction and service for any third parties) by registered mail, return
receipt requested, directed to the party being served at its address provided
in or pursuant to this Agreement (and service so made shall be deemed complete
three (3) days after the same has been posted as aforesaid) or by personal
service or in such other manner as may be permissible under the rules of said
court. The Company hereby waives any right to a jury trial in connection with
any litigation pursuant to this Agreement.

            (i)   Assignment and Indemnity.  The Company consents to each
Purchaser's assignment of all or any part of such Purchaser's rights under
this Agreement and the Operative Documents.  The Company shall indemnify and
defend and hold each Purchaser and any assignee of such Purchaser's interests
harmless from any actions, costs, losses or expenses (including attorneys'
fees) arising out of such assignment, this Agreement and the Operative
Documents.

            (j)   Fees and Expenses. Each party shall pay the fees and
expenses of its advisors, counsel, accountants and other experts, if any, and
all other expenses, incurred by such party incident to the negotiation,
preparation, execution, delivery and performance of this Agreement; provided,
however, that the Company shall pay $7,500 to Gryphon Master Fund, L.P.
("Gryphon"), the lead Purchaser, to reimburse Gryphon for the fees and
expenses (including attorneys' fees and expenses) incurred by it in connection
with the preparation, negotiation, execution, delivery and performance of this
Agreement. Such amount shall be paid to Gryphon by wire transfer of
immediately available funds to an account designated by Gryphon no later than
the second business day following the date of this Agreement.

            IN WITNESS WHEREOF the undersigned have executed this Agreement as
of the first date above written.

                                6AMENDMENT AGREEMENT

         This amendment agreement (the "Agreement") entered into this 15th day
of March, 2006 between SiriCOMM, Inc. ("SiriCOMM"), a Delaware corporation
having its principal place of business located at 2900 Davis Boulevard, Suite
130, Joplin, Missouri, 64804 and Idling Solutions, L.L.C., a Texas limited
liability company having its principal place of business located at 5000 Legacy
Drive, Suite 470, Plano, Texas, 75024 ("Idling Solutions").

         WHEREAS, Idling Solutions and SiriCOMM entered into the Network Access
Services Agreement (the "Network Access Services Agreement") dated February 7,
2005 which will stay in full force and effect except for the changes stated
herein;

         NOW, THEREFORE, for and in consideration of the premises, and other
good and valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties agree to these amended and restated terms and
conditions as follows:

         1.   SiriCOMM and Idling Solutions agree to amend the Network Access
              Service Agreement (a copy of which is attached), such that the fee
              in Section 3 is lowered from $5.00/$4.00 per truck per month
              initially to $3.00 per truck per month. Said $3.00 charge will be
              for a maximum of 1 megabyte of data on a pooled basis. Any
              overages shall be billed on a pro rata basis. In no event shall
              the charges exceed $5.00 per truck per month.

         2.   Amend Section 14 of the Network Access Services Agreement to
              include: at Idling Solutions sole discretion, if SiriCOMM does not
              provide an operational network called for in the Network Access
              Services Agreement byApril 15th, 2006 (pulling data from a test
              truck and flashing the memory with new program code into the pulse
              box via the SiriCOMM Network) and by April 30th deploy one hundred
              and fifty (150) 915 mhz base stations mutually agreed upon
              locations (so long as Cadco has made the 915 mhz radios reasonably
              available to meet the April 30th deployment and SiriCOMM will use
              best efforts to complete the balance of their sites as soon as

                                       1
<PAGE>

              possible), then Idling Solutions is released to find an
              alternative network and to no longer be obligated to SiriCOMM to
              utilize its network. Notwithstanding anything to the contrary
              contained herein, in the event DirecTruck, a company affiliated
              with Idling Solutions, fails to deliver the technology related to
              the Pulse Box to SiriCOMM byApril 15th, 2006, SiriCOMM will have
              ten (10) days from the receipt of such technology to provide
              Idling Solutions an operational network and shall be provided an
              additional forty-five (45) days to deploy the one hundred and
              fifty (150) 915 mhz base stations. In the event SiriCOMM fails to
              meet this revised time-frame, Idling Solutions will be released to
              find an alternative network and no longer be obligated to utilize
              SiriCOMM's network.

         3.   Idling Solutions will agree to utilize the SiriCOMM network to
              exclusively carry Idling Solutions data so long as SiriCOMM
              maintains its network up to the requirements of the Network Access
              Services Agreement.

         4.   Idling Solutions has the right to purchase the Pulse Box from
              SiriCOMM for direct vendor cost plus 10%. The current vendor cost
              quote from Cadco for the Pulse Box is $330.00. It is understood
              that as the price is decreased for SiriCOMM so shall the cost to
              IS be decreased proportionately. Payment terms to SiriCOMM will be
              50% down, net 30 on orders of a minimum of 100 units. Idling
              Solutions and SiriCOMM will work together to find the best
              mutually acceptable vendor to supply the Pulse Boxes.

         5.   Idling Solutions projection of unit sales is attached as Exhibit
              A.

         6.   Should SiriCOMM declare bankruptcy, become insolvent or fail to
              deliver on a timely basis the Pulse Box to Idling Solutions, then
              Idling Solutions will have the right to buy from the SiriCOMM
              vendor under the same terms and conditions as provided to SiriCOMM
              or seek the manufacture of the Pulse Box from a third party and

                                       2
<PAGE>

              either have access to the SiriCOMM Network or if not available for
              any reason to be able to relocate all of its customers to another
              network.

         7.   SiriCOMM will guarantee timely delivery of data to Idling
              Solutions to accommodate their needs for warranty or MERC credits,
              in accordance with the Network Services Agreement. In return,
              Idling Solutions will commit to utilize the SiriCOMM Network for
              the trucks on which the Pulse Box is installed as long as the
              network performs to standards set by the EPA for MERCs. The
              current ramp up for the 2nd quarter is 4,600 units.

         8.   As previously discussed and agreed, SiriCOMM will provide the
              requested networking equipment at the sites of J.B. Hunt's
              headquarters and terminals and on any other freight carrier which
              has more than 500 trucks and has committed to the Idling Solutions
              System.

         9.   Both SiriCOMM and Idling Solutions must mutually agree to any
              changes of the Pulse Box Design and Software for Idling Solutions
              use. Such authorization, whether requested by either Idling
              Solutions or SiriCOMM, will not unreasonably be withheld.

         10.  Except as supplemented and amended by this Agreement and such
              conforming changes as necessary to reflect the modification
              herein, all of the provisions of the Network Access Services
              Agreement shall remain in full force and effect from and after the
              effective date of this Agreement.

         NOTWITHSTANDING anything to the contrary, SiriCOMM may not knowingly
sell the Pulse Box to any trucking company or competitor of Idling Solutions,
that would utilize the pulse box to gather information for the purposes of
MERC's.

         This Agreement has been duly authorized and approved by all required
corporate action by each company and does not violate their respective
certificates of incorporation or bylaws.

                                       3
