                                    RECITALS

     TSET, as EdgeAudio's sole shareholder,  has authorized EdgeAudio's Articles
of   Incorporation  to  be  amended  to  authorize  and  issue  Preferred  Stock
("Preferred Stock") of EdgeAudio to Holbrook.

     As a condition to Holbrook's  acquisition of the Preferred  Stock,  certain
provisions of the Agreement must be amended.

                                    AMENDMENT

     NOW THEREFORE,  for valuable consideration,  the receipt and sufficiency of
which are hereby  acknowledged,  the  parties  agree to amend the  Agreement  as
follows:

     1.   Holbrook  shall hereby be added to the  Agreement as a party and shall
          have privity of contract with all other parties to the Agreement.

     2.   Section 5(a) of the Agreement shall be amended as follows:

          Effective the date of this  Amendment (a) Holbrook shall replace James
          Eric Anderson as a member of  EdgeAudio's  board of directors,  and at
          that time Holbrook  shall also become  Chairman of the Board,  and (b)
          Richard A.  Papworth  ("Papworth")  shall  replace J. David Hogan as a
          member of EdgeAudio's board of directors and Papworth shall be elected
          chief financial officer of EdgeAudio.

     3.   The  following  language  found at the end of the  first  sentence  of
          Section  5(c) of the  Agreement  shall  be  deleted:  "but  with  such
          consultations  and   determinations  as  are  consistent  with  TSET's
          ownership of EdgeAudio".

     4.   The term  "TSET" at the end of the first  sentence of Section 6 of the
          Agreement shall be changed to "its  shareholders." The second sentence
          of Section 6 of the  Agreement  shall be  amended to read as  follows:
          "The shareholders  intend that the Corporate  Business be conducted by





          EdgeAudio  in  substantially  the same  manner as  conducted  prior to
          execution and delivery of this Amendment and the Agreement."

     5.   The last  sentence of Section 8 of the  Agreement  shall be amended to
          read as follows:  "As an additional  inducement  to management  and to
          ensure  participation by management in the potential future success of
          EdgeAudio,  TSET, as sole  stockholder of EdgeAudio,  hereby agrees to
          reserve up to 20% of EdgeAudio's  authorized  capital stock to be used
          in  Programs  to be  adopted by  EdgeAudio's  board of  directors  and
          consents to the full  participation of management  therein.  The terms
          for such  participation  in the EdgeAudio  related  Programs  shall be
          established by EdgeAudio's board of directors."

     6.   Section  9 of the  Agreement  shall be  deleted  in its  entirety  and
          replaced by the following:  "TSET shall use its best efforts to assist
          EdgeAudio  to  negotiate  and  consummate  a long  term  manufacturing
          agreement with Eterna International S.A. de C.V. and Johnstowne,  Inc.
          related to the  manufacture  of product for  EdgeAudio  upon  mutually
          agreeable terms."

     7.   Section  10 of the  Agreement  shall be deleted  in its  entirety  and
          replaced by the following:

          (a)  In the event that before the earlier of the date all the Earn-out
               Shares have been issued, the date the Earn-out Period expires, or
               the  date of an IPO of  EdgeAudio  stock,  TSET  and/or  Holbrook
               propose to sell part or all of their  EdgeAudio stock (other than
               in an IPO) to a bona fide third  party who is willing to purchase
               such stock, and EdgeAudio, TSET and Holbrook have all declined to
               exercise any rights to purchase such shares pursuant to Section 3
               of the Shareholders Agreement of even data herewith,  TSET and/or
               Holbrook must, pursuant to the timing requirements of Section 3.4
               of the  Shareholders  Agreement,  offer to sell such stock to the
               Stockholders,  at the same  price  and on the  same  terms of the
               proposed  transfer.  The  offer  shall  be  made  by  giving  the
               Stockholders   written  notice  of  the  proposed  transfer  (the
               "Proposed Transfer Notice") stating (1) that TSET and/or Holbrook
               intends to transfer part or all of their stock, and (2) the terms
               of the proposed  transfer,  including the name and address of the
               proposed  transferee,  the  transfer  price,  and  the  terms  of
               payment.

          (b)  For 30 days after the  Stockholders  receive a Proposed  Transfer
               Notice, the Stockholders shall have the option to purchase all of
               the offered  stock.  If the  Stockholders  elect to purchase  the
               offered stock the option shall be exercised upon the Stockholders
               giving written notice to TSET and/or  Holbrook  during the option
               period, which notice shall demonstrate that the Stockholders have
               obtained  financing or a commitment  for financing  sufficient to
               fund the purchase.  In the event the  Stockholders  are unable to
               agree  on  how  many  shares  of  stock  each  Stockholder  shall
               purchase,  each Stockholder  shall have the right to purchase the


                                       2


               offered  shares  in  proportion  to  the  respective   number  of
               EdgeAudio  Shares set forth opposite such  Stockholder's  name in
               Section 1.

          (c)  Following  exercise  of the option,  the parties  shall close the
               purchase no later than 60 days after the  Stockholders  receive a
               Proposed Transfer Notice.

          (d)  If the option to purchase is not  exercised by the  Stockholders,
               TSET and/or  Holbrook may complete the  transfer(s),  but only in
               strict  accordance  with  the  terms  previously  offered  by the
               transferee  stated to the  Stockholders as required under Section
               10(a).

     8.   Section 13 of the Agreement shall be deleted in its entirety.

     9.   Except as expressly amended by this Amendment,  all other terms of the
          Agreement shall remain in full force and effect.

     10.  This  Amendment may be signed in any number of  counterparts,  each of
          which shall be an original,  with the same effect as if the signatures
          thereto and hereto were upon the same  instrument.  This Amendment may
          be executed by facsimile signatures,  each of which shall be deemed an
          original.

     11.  Section 16 of the Agreement shall be incorporated  into this Amendment
          by  this  reference  and  shall  fully  apply  to the  terms  of  this
          Amendment.

     12.  The  following  shall be added  onto the end of  Section  16(f) of the
          Agreement:  "TO BRYAN HOLBROOK,  142 N. Blue Sage, Layton,  Utah 84040
          (801) 544-0690".

     13.  Except  as set  forth  below,  EdgeAudio  shall  not  take  any of the
          following actions or participate in the following transactions without
          TSET's prior written  approval:  (a) the sale of all or  substantially
          all of its assets; (b) a merger, consolidation or similar transaction;
          (c)  confession  of any  judgment;  (d)  amendment  of its articles of
          incorporation or bylaws;  (e) dissolution,  winding up or liquidation;
          (f) the filing of any  voluntary  petition in  bankruptcy;  or (g) any
          action that requires  approval under the Oregon  Business  Corporation
          Act (the "Act") of more than a majority of the shares entitled to vote
          on the  matter.  Notwithstanding  the  previous  sentence  or the Act,
          TSET's  approval  shall not be required for any action or  transaction
          that  would  result in TSET  receiving  or  retaining  shares or other
          consideration equal in value to the consideration paid by TSET for its
          shares of EdgeAudio plus any direct capital contributions made by TSET
          to EdgeAudio.

     14.  Promptly after  execution of the Amendment,  EdgeAudio shall issue new
          share certificates to document the ownership of its shares.

     15.  EdgeAudio shall cooperate with TSET and supply information  related to
          EdgeAudio as  necessary to enable TSET to comply with its  obligations
          to supply  information and make reports  required by federal and state
          securities law.

                                       3



     16.  EdgeAudio, Robert I. Lightman, LYNK Enterprises, Inc., J. David Hogan,
          Eric J.  Alexander,  and Eterna  Internacional,  S.A.  de C.V.  hereby
          release  TSET and TSET hereby  releases the above  referenced  parties
          from  any  and  all  claims  and  causes  of  action   identified   or
          unidentified that may have arisen after May 4, 2000, related to TSET's
          obligation  to provide  additional  funding to  EdgeAudio or otherwise
          arising from any cause  whatsoever to the extent related to or arising
          out of the Agreement.  This release is intended to release only claims
          related to breaches and causes of action arising on or before the date
          of this Amendment,  but is not intended to and does not release any of
          the above referenced  parties from their continuing  obligations under
          the Agreement as modified by this Amendment.

     17.  EdgeAudio  acknowledges  that  TSET  has  satisfied  $186,100  of  its
          obligation  under  Section  7 of  the  Agreement  to  provide  working
          capital.  TSET's  obligation  to provide the  remainder of the funding
          described  in  Section 7 of the  Agreement  shall be  suspended  until
          Holbrook has  contributed the full $700,000 he is obligated to provide
          under the Preferred Stock Purchase Agreement of even date herewith.

     18.  Section 14 of the Agreement shall be incorporated  into this Amendment
          and the Preferred Stock Purchase Agreement,  and any Claims related to
          this  Amendment or the Preferred  Stock  Purchase  Agreement  shall be
          resolved using the dispute resolution  mechanism  contained in Section
          14 of the Agreement.

     19.  The  parties  agree to  cooperate  with each other and take such other
          actions and sign such other documentation  following the closing as is
          necessary to effectuate the intent of this Amendment.
