                                    RECITALS

     WHEREAS,  on April 18, 2000,  TSET and  EdgeAudio  entered into a Letter of

          "EdgeAudio Shares"):

          Eterna Internacional, S.A. de C.V.                 25,000

              Total                                         100,000

          The  EdgeAudio  Shares  shall be assigned to and acquired by TSET free
          and  clear  of any  and all  liens,  claims,  encumbrances,  sureties,
          restrictions  of any kind  whatsoever  on their  free  transferability
          (other than  applicable  securities  law  restrictions),  options,  or
          rights of any third parties,  including preemptive rights or claims of
          any nature whatsoever as well as any and all rights attaching thereto.

     2.   VALUATION.   Pursuant  to   negotiations,   TSET  and  EdgeAudio  have
          established an  agreed-in-principle  aggregate  earn-out valuation for
          EdgeAudio of $6,750,000  (the "Aggregate  Valuation"),  with an agreed
          initial   valuation  for   EdgeAudio  of   $3,000,000   (the  "Initial
          Valuation").

     3.   INITIAL EXCHANGE OF SHARES. (a) Each of the Stockholders shall assign,
          transfer, and convey to TSET all of the EdgeAudio Shares owned by them
          (as indicated in Section 1 hereof) in exchange initially for 1,298,701
          TSET Shares, to be allocated among the Stockholders as follows:

          LYNK Enterprises, Inc.                      714,286 TSET Shares
          Eterna Internacional, S.A. de C.V.          324,675 TSET Shares
          Robert I. Lightman                          129,870 TSET Shares
          J. David Hogan                               64,935 TSET Shares
          Eric J. Alexander                            64,935 TSET Shares

          The TSET Shares set forth in this Section 2 shall  constitute the sole
          compensation  of the  Stockholders  for the EdgeAudio  Shares owned by
          each of them.

          (b)  Simultaneously  with the execution and delivery of this Agreement
               by the parties:

               (i)    each  of  the   Stockholders   shall   deliver   to  TSET,
                      certificates  representing  all  of the  EdgeAudio  Shares
                      owned by them,  accompanied  by  appropriate  stock powers
                      endorsed in blank, and shall cause the EdgeAudio Shares to
                      be  registered  in the name of TSET on  EdgeAudio's  share
                      registry and perform any and all other actions required by
                      applicable  law  to  evidence  TSET's   ownership  of  the
                      EdgeAudio Shares; and

Page 2

               (ii)   TSET   shall   deliver   to  each   of  the   Stockholders
                      certificates  representing the number of TSET Shares to be
                      acquired  by  them,  shall  cause  the TSET  Shares  to be
                      registered  in the  names of each of the  Stockholders  on
                      TSET's  share  registry  and cause the  transfer  agent to
                      provide  documentation  thereof to the  Stockholders,  and
                      perform any and all other  actions  required by applicable
                      law to  evidence  ownership  of the  TSET  Shares  by each
                      Stockholder.

               Immediately following the exchange of shares contemplated in this
               Subsection (b), TSET shall own 100% of EdgeAudio's issued and
               outstanding capital stock and EdgeAudio shall be a wholly owned
               subsidiary of TSET.

          (c)  The Stockholders  understand and acknowledge that the TSET Shares
               to be received by them pursuant to the Initial  Valuation and the
               Earnout  Valuation shall be subject to, and the Stockholders each
               hereby  agree  to at all  times  observe  and  comply  with,  the
               conditions,   limitations,   and   restrictions   noted   on  the
               certificates  representing  the TSET  Shares,  in addition to any
               other  restrictions  set forth in  applicable  federal  and state
               securities  laws.  The  following  conditions,  limitations,  and
               restrictions  noted on the  certificates  shall be limited to the
               following:

               (i)    Investment  stock.  Restriction  on  transfer.  The shares
                      represented  by this  certificate  have been  acquired for
                      investment and may not be sold or  transferred  unless the
                      same are  registered  under the Securities Act of 1933, or
                      the company receives an opinion from counsel  satisfactory
                      to it that such  registration  is not required for sale or
                      transfer  or that the  shares  have been  legally  sold in
                      brokered  transactions  pursuant  to rule 144 of the rules
                      and regulations of the Securities and Exchange  Commission
                      promulgated under the Securities Act of 1933.

          (d)  Any taxes,  levies,  or other  charges  assessed  against,  or in
               connection   with   acquisition  of,  the  TSET  Shares  by  each
               Stockholder  pursuant to this Agreement  shall be for the account
               of, and shall be born solely by, each such Stockholder.

          (e)  Any  compensation for finder's fee payable by EdgeAudio or any of
               the  Stockholders  to any  person  relating  to the  transactions
               contemplated  by this  Agreement  shall  be paid  out of the TSET
               Shares to be received by them,  the  parties  agreeing  that TSET
               shall have no financial or other  responsibility  whatsoever  for
               payment of any such  compensation.  TSET shall be responsible for
               paying any finder's fee payable to any finder or broker initially
               contacted by TSET.

     4.   EARN-OUT AND ISSUANCE OF  ADDITIONAL  TSET SHARES.  (a) An  additional
          $3,750,000 worth of TSET Shares (the "Earn-out Shares"),  representing
          the  difference  between  the  Aggregate  Valuation  and  the  Initial
          Valuation,  (hereinafter  referred  to as the  "Earn-out  Valuation"),
          shall in the  future  be  issued  to the  Stockholders  in five  equal

                                     Page 3
<PAGE>

          installments,  each  equal  to 20% of the  Earn-out  Valuation  (i.e.,
          $750,000  of Earn-out  Shares per  installment),  if and as  EdgeAudio
          achieves five  forecasted  cumulative  gross revenue  milestones  (the
          "Revenue  Milestones")  over the 5-year period next following the date
          of this Agreement (the "Earn-out  Period"),  which Revenue  Milestones
          are hereby established and agreed to by the parties as follows:

                                                Cumulative Gross Revenue
                                        Earned Since the Date of This Agreement
                                        ---------------------------------------

              Revenue Milestone 1                       $1,764,271.00
              Revenue Milestone 2                       $5,539,538.00
              Revenue Milestone 3                      $10,285,024.00
              Revenue Milestone 4                      $15,793,368.00
              Revenue Milestone 5                      $22,187,203.00

          thus constituting aggregate forecasted revenue of $22,187,203.00 to be
          earned on or  before  the end of the  Earn-out  Period.  The  Earn-out
          Shares  shall be issued  to the  Stockholders  as soon as  practicable
          following   TSET's   receipt  of  written   certification   signed  by
          EdgeAudio's  chief  financial  officer that EdgeAudio has achieved the
          particular  Revenue  Milestone in question,  such  certification to be
          dated as of the date EdgeAudio first achieves the Revenue Milestone in
          question (the "Certification"). The Earn-out Shares shall be allocated
          among the  Stockholders  on a pro rata  basis in  proportion  to their
          ownership  of the  EdgeAudio  Shares  as set  forth in  Section  1. If
          EdgeAudio  fails to achieve any given Revenue  Milestone,  no Earn-out
          Shares shall be issued with respect thereto.  No Earn-out Shares shall
          be issued with  respect to any Revenue  Milestone  until  EdgeAudio is
          able to issue a  Certification  to TSET. The number of Earn-out Shares
          to be issued in connection with  achievement of any Revenue  Milestone
          shall be calculated as follows:

                      (EAV)(0.20)/ACP, where

                      EAV = Earn-out Valuation, and

                      ACP = the average closing price for the TSET Shares for
                      the 5 trading days immediately preceding the date of the
                      Certification.

          (b)  In the event  shares of  EdgeAudio  are sold during the  Earn-out
               Period in connection  with an initial public  offering (an "IPO")
               of  EdgeAudio  stock  that  demonstrates  that the  market  value
               immediately  before the IPO,  upon which  market value the IPO is
               based, equals or exceeds the Aggregate Valuation, EdgeAudio shall
               be  presumed  on the date of the IPO to have  reached all Revenue
               Milestones not previously reached,  and the Stockholders shall be
               entitled to receive all the Earn-out  Shares they would have been
               entitled to receive if EdgeAudio would have actually  reached all
               the Revenue Milestones on or before the date of the IPO.

          (c)  As mentioned in the Recitals,  the  transaction  contemplated  by
               this Agreement is intended to qualify as a  reorganization  under
               IRC Section  368(a)(1)(B) as amended.  Accordingly,  in the event
               TSET (1) enters into an agreement  to merge into another  company
               in a transaction where TSET is not the surviving corporation, (2)
               enters  into  an  agreement  to  otherwise  be  absorbed  into or
               acquired  by another  company,  or (3) is  involved  in or is the
               subject of a  transaction  in which TSET  ceases to be a publicly
               traded  company  (hereafter  referred  to as a  "Privatization"),
               EdgeAudio   shall   be   presumed   immediately   prior   to  the
               Privatization   to  have  reached  all  Revenue   Milestones  not
               previously  reached,  and TSET shall  prior to the  Privatization
               issue to the Stockholders all the Earn-out Shares they would have
               been entitled to receive if EdgeAudio would have actually reached
               all  the  Revenue  Milestones  on  or  before  the  date  of  the
               Privatization.

          (d)  Except  as  otherwise  provided  above,  TSET  shall  issue  each
               installment of Earn-out Shares to the Stockholders  within ninety
               days after EdgeAudio reaches each Revenue Milestone.

          (e)  Neither  the right to receive  Earn-out  Shares nor any  interest
               therein shall be assignable by any Stockholder  except by will or
               operation  of law,  and no  Stockholder  shall  have  any  voting
               rights,  rights  to  receive  dividends  or  other  distributions
               thereon,  or any  other  rights  of a  Stockholder  of TSET  with
               respect  to any  Earn-out  Shares  until  they are  issued to the
               Stockholder.

          (f)  The  Stockholders and TSET agree that some of the Earn-out Shares
               issued to  Stockholders  shall be in payment of  interest  at the
               rate required under Treas.  Reg. Section 1.483-1,  for the number
               of months  between the closing and the  delivery of the  Earn-out
               Shares in accordance with Treas. Reg. Section1.483-1, on the fair
               market  value of the total  number of Earn-out  Shares  issued to
               Stockholders.  TSET shall  issue  separate  certificates  for the
               portion of the Earn-out Shares that constitutes interest.

          (g)  If after the date hereof and prior to the issuance of the initial
               or  Earn-out  Shares  to be issued to  Stockholders  pursuant  to
               Sections 3 and 4, the  outstanding  shares of TSET  common  stock
               are, without the receipt of new consideration by TSET, increased,
               decreased,  changed into, or exchanged for a different  number or
               kind of  shares or  securities  of TSET  through  reorganization,
               reclassification,  stock  dividend,  stock split,  reverse  stock
               split,  or similar  change in TSET's  capitalization,  TSET shall
               issue and deliver to the  Stockholders  in addition to or in lieu
               of the TSET Shares specified in Sections 3 and 4, voting stock of
               TSET in  equitably  adjusted  amounts.  In the  event of any such
               change in TSET's  capitalization,  all  references to TSET Shares
               herein shall refer to the number of TSET Shares as thus adjusted.

<PAGE>

          (h)  No  fractional  shares  of TSET  stock  shall  be  issued  to any
               Stockholder  hereunder,  and any  fractional  share to which  any
               Stockholder  would  otherwise be entitled  shall be rounded up to
               the nearest whole share.

     5.   MANAGEMENT.  (a) Following TSET's acquisition of the EdgeAudio Shares,
          EdgeAudio's  board of directors  shall be  comprised of the  following
          individuals:

                     Winthrop E. Jeanfreau
                     Robert I. Lightman
                     J. David Hogan
                     James Eric Anderson
                     Jeffrey D. Wilson (representing TSET)

     Except as provided  below,  such directors  shall serve in accordance  with
EdgeAudio's  bylaws  and  applicable  law.  Winthrop  E.  Jeanfreau,  Robert  I.
Lightman,  and J. David Hogan shall serve as directors  until the earlier of (1)
death or  resignation,  (2) the  issuance of all the  Earn-out  Shares,  (3) the
expiration of the Earn-out Period, or (4) removal for "Cause".  Cause shall mean
(1) an act of fraud, embezzlement, or theft constituting a felony; (2) an act or
omission detrimental to EdgeAudio's interests involving  intentional  misconduct
or a knowing violation of law; or (3) an act of dishonest conduct that seriously
undermines  such  director's  integrity.  If  Winthrop E.  Jeanfreau,  Robert I.
Lightman,  or J. David Hogan  ceases to be a director  before the earlier of the
date all the Earn-out  Shares have been issued or the date the  Earn-out  Period
expires,  the  resulting  vacancy on the board shall be filled by an  individual
appointed by the remaining member or members of such group. Until the earlier of
the date all the  Earn-out  Shares  have been  issued  or the date the  Earn-out
Period expires,  EdgeAudio's board of directors shall continue to consist of not
more than 5 members. Jeffrey D. Wilson shall serve as Chairman of the Board.

     6.   THE CORPORATE  BUSINESS.  The parties  understand and acknowledge that
          the   "Corporate   Business"   of   EdgeAudio   is  the   development,
          manufacturing, marketing, and selling via the Internet stereo speakers
          and accessories,  owning or licensing all intellectual property rights
          related  thereto,  and such other  activities as may enhance the value
          and name  recognition  of  "EdgeAudio",  all with a view to  advancing
          EdgeAudio's  best interests and maximizing  EdgeAudio's  profitability
          and success for the benefit of TSET.  TSET intends that the  Corporate
          Business be conducted by EdgeAudio in substantially the same manner as
          conducted prior to TSET's acquisition of the EdgeAudio Shares.

     7.   WORKING  CAPITAL.  TSET shall provide and make  available to EdgeAudio
          working  capital  in  the  aggregate  amount  of up to  $400,000  (the
          "Funding")  during the  period  following  the date of this  Agreement
          until  December  31,  2001  (the  "Funding  Period").  To  the  extent
          required,  TSET  may use its own  shares  in  order  to  arrange  for,
          procure,  and ensure availability of the Funding;  provided,  however,

          that TSET's  obligation  to provide the Funding shall not be construed
          as or  constitute  any  assumption  of any  obligation  regarding  any
          indebtedness,  operating expenses,  or other financial  liabilities of
          EdgeAudio  or  the  Stockholders.   Provision  of  the  Funding  shall
          constitute  the  sole  financial  obligation  of  TSET  to  EdgeAudio;
          provided,  however,  that TSET may  elect,  but is not  obligated,  to
          provide to EdgeAudio  additional funding in addition to the Funding in
          appropriate  cases to be  determined  by TSET in its sole and absolute
          discretion.  Within  60 days of the  execution  and  delivery  of this
          Agreement, EdgeAudio's board of directors shall establish an operating
          budget,  including  provision  for,  among other  things,  the prudent
          expenditure  and  conservation  of funds for working  capital over the
          Funding  Period while  achieving  the overall  goals of the  Corporate
          Business.  In the event  working  capital in excess of the  Funding is
          required in connection with any  acceleration of EdgeAudio's  business
          plan,  the  Stockholders  may,  collectively  or in  any  combination,
          subject  to  TSET's  prior   written   consent   which  shall  not  be
          unreasonably withheld),  participate in the provision thereof, subject
          to terms and conditions therefor to be agreed at that time.

     8.   OPTIONS AND OTHER  PROGRAMS.  TSET  intends to adopt for  itself,  and
          intends that EdgeAudio adopt stock option, incentive,  profit-sharing,
          savings, and other similar programs  (collectively,  the "Programs" as
          soon as practicable after the date hereof. The terms and conditions of
          participation,  contribution, matching, vesting, and other elements of
          the  Programs  shall  be  established  by  the  respective  boards  of
          directors of TSET and EdgeAudio.  EdgeAudio's  directors and executive
          management   (collectively,   "management")   shall  be   entitled  to
          participate  in  Programs  to be  adopted  by  TSET,  subject  to such
          conditions and restrictions  imposed upon such participation by TSET's
          board of directors.  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,  subject to
          the terms for such  participation  to be  established  by  EdgeAudio's
          board of  directors;  provided,  however,  that the  final  terms  and
          conditions of the Programs  adopted by EdgeAudio's  board of directors
          shall be subject to TSET's prior written  consent  (which shall not be
          unreasonably withheld).

     9.   MANUFACTURING  FACILITIES.   Upon  request  by  EdgeAudio's  board  of
          directors,  TSET agrees to exert its good faith best efforts to assist
          EdgeAudio  in  ensuring,   whether  by  contract  or  otherwise,  that
          manufacturing  facilities  sufficient for the conduct of the Corporate
          Business will continue to be available to EdgeAudio.

     10.  FUTURE EVENTS.  (a) At an appropriate  and mutually agreed time in the
          future,  TSET  intends  to give due and good  faith  consideration  to
          effecting  a  transaction  pursuant  to which  EdgeAudio  may become a
          publicly-owned entity (the "Reconstitutive Decision"). In the event of
          any Reconstitutive  Decision, TSET (or its nominees) shall be entitled
          to retain (or share with such  nominees) not less than a  nondilutable
          30% ownership interest in EdgeAudio.

          (b)  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 proposes to sell part
               or all of EdgeAudio's stock (other than in an IPO) to a bona fide
               third  party who is willing to  purchase  such  stock,  TSET must
               first  offer to sell the stock to the  Stockholders,  at the same

Page 7
<PAGE>

               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 intends to transfer part or all the 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.

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

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

          (e)  If the option to purchase is not  exercised by the  Stockholders,
               TSET may complete  the  transfer,  but only in strict  accordance
               with the terms previously offered by the transferee stated to the
               Stockholders as required under Section 10(b).

     11.  REPRESENTATIONS  AND  WARRANTIES  OF EDGEAUDIO  AND THE  STOCKHOLDERS.
          EdgeAudio and each of the Stockholders,  jointly and severally, hereby

               herein.  EdgeAudio  is duly  licensed  or  qualified  and in good
               standing  in all  jurisdictions  in which  the  character  of the
               properties  owned or leased by it or the nature of the  Corporate
               Business requires it to be so licensed or qualified. Complete and

                      constitutive documents;

                      termination of, or constitute a default,  event of default
                      (or an event which with  notice,  lapse of time,  or both,
                      would constitute a default or event of default), under the
                      terms of any

                      (A)   contracts, agreements, commitments, or other binding
                            undertakings,  whether  or not  reduced  to  writing
                            (collectively, "Contracts"), or

                      (B)   permits, authorizations,  approvals,  registrations,

                            governmental,    administrative,    or    regulatory
                            authority (collectively, "Permits"),

               to which  EdgeAudio or any of the  Stockholders  is a party or by
               which  EdgeAudio  or  any  of the  Stockholders  or any of  their
               respective or collective  securities,  properties,  or businesses
               are bound;

               (iii)  to their knowledge  constitute a violation by EdgeAudio or
                      any of the Stockholders of any

                      (A)   laws,  rules,  or regulations  of any  governmental,
                            administrative,      or     regulatory     authority

               (iv)   result in the creation of any lien,  claim, or encumbrance
                      (collectively,  "Liens")  upon  EdgeAudio  or  any  of its
                      assets or properties,  the EdgeAudio Shares, or any of the
                      Stockholders.

          (c)  ACTIONS AND  PROCEEDINGS.  Except as disclosed in Exhibit 11(c-1)
               attached  hereto and made a part hereof for all  purposes,  there
               are  no  actions,   suits,  claims,  or  legal,   administrative,
               arbitration,  or other alternative dispute resolution proceedings
               or investigations  (collectively,  "Proceedings") (whether or not
               the defense  thereof or liability with respect thereto is covered
               by policies of  insurance)  pending or, to the best  knowledge of
               EdgeAudio  and  any of the  Stockholders,  threatened,  to  which
               EdgeAudio  or any of the  Stockholders  is or  would  be a  party
               including,   without  limitation,   any  Proceeding  which  could
               reasonably  be  expected  to  restrain,   prevent,   or  prohibit
               EdgeAudio  or any  of  the  Stockholders  from  consummating  the
               transactions  contemplated  herein, or to obtain damages or other
               relief  in  connection   with,  this  Agreement  or  any  of  the

Page 9

               transactions  contemplated herein. Except as disclosed in Exhibit
               11(c-2)  attached hereto and made a part hereof for all purposes,
               there is no Judgment  outstanding  against  EdgeAudio.  Except as
               disclosed  in  Exhibit  11(c-3)  attached  hereto and made a part
               hereof for all purposed,  each Stockholder  severally  represents
               and  warrants  there  is no  Judgment  outstanding  against  such
               Stockholder.  Any breach of the  representation  and warranty set
               forth in the preceding sentence shall result in liability only to
               the Stockholder who breached such representation and warranty.

               contemplated herein have been carried on with the intervention or
               assistance  of any party  acting in behalf of EdgeAudio or any of
               the  Stockholders  in such a manner  as to give rise to any shall
               claim against EdgeAudio or any of the Stockholders,  individually
               or  collectively,  for any  broker's or  finder's  fee or similar
               compensation  (whether  payable in cash,  EdgeAudio  Shares,  any
               interest in EdgeAudio,  or otherwise) in connection therewith. No
               basis exists  whatsoever for any such broker's or finder's fee or
               similar compensation to be payable by TSET.

          (e)  AUTHORITY.  EdgeAudio  has  all  necessary  corporate  power  and
               authority,  and each of the  Stockholders  have the power,  legal
               capacity,  and  authority,  to execute and deliver this Agreement
               and  perform  all of its or his  obligations  hereunder;  and the
               execution, delivery, and performance by EdgeAudio and each of the
               Stockholders  of this  Agreement has been duly  authorized by all
               necessary corporate action on its part or is within the authority
               of the person  executing and  delivering  the same, and is within
               the  authority  of  each  of  the  Stockholders.  This  Agreement
               constitutes  the  legal,   valid,  and  binding   obligations  of
               EdgeAudio and each of the Stockholders,  enforceable  against any
               and all of them in accordance  with the terms  hereof,  except as
               may   be   limited   by   applicable   bankruptcy,    insolvency,
               reorganization, or other similar laws affecting creditors' rights
               and general principles of equity.

          (f)  TAXES AND TAX RETURNS.  Except as  disclosed  in Exhibit  11(f-1)
               attached hereto and made a part hereof for all purposes:

               (i)    EdgeAudio  has filed all tax  returns  and  reports of all
                      Taxes (as hereinafter  defined) required to be filed by it
                      and has  timely  given  and  delivered  all  Tax  notices,
                      accounts,  and information required to be given by it with
                      respect to Taxes for which  EdgeAudio  may be liable.  All
                      information  provided in such returns,  reports,  notices,
                      accounts,  and  information  was,  when  filed  or  given,
                      complete and  accurate.  All Taxes  required to be paid by
                      EdgeAudio  that were due and payable  prior to the date of
                      this  Agreement  have been paid in full,  except  for such
                      Taxes as are being  contested in good faith by appropriate

Page 10
<PAGE>

                      proceedings  and for  which  adequate  reserves  are being
                      maintained.   Adequate   provision  in   accordance   with
                      generally  accepted  accounting  principles   consistently
                      applied have been made in EdgeAudio's financial statements
                      for the  payment of all Taxes for which  EdgeAudio  may be
                      liable for the periods  covered  thereby that were not yet
                      due and  payable  as of the  date  hereof,  regardless  of
                      whether the liability for such Taxes is disputed;

               (ii)   There  are  no  pending  or,  to  the  best  knowledge  of
                      EdgeAudio  and each  Stockholder,  threatened,  audits  or
                      investigations  relating to any Taxes for which  EdgeAudio
                      may become directly or indirectly  liable. No deficiencies
                      for any Taxes have been  proposed,  asserted,  or assessed
                      against  EdgeAudio  and no state of  facts  exists  or has
                      existed that would  constitute  grounds for the assessment
                      of  a  Tax  liability  against  EdgeAudio.  There  are  no
                      agreements  in effect to extend the period of  limitations
                      for the  assessment  or  collection of any Taxes for which
                      EdgeAudio  may become  liable and no requests for any such
                      agreements are pending;

               (iii)  Except as disclosed in Exhibit 11(f-2) attached hereto and
                      made  a  part  hereof  for  all  purposes,  EdgeAudio  has
                      withheld  from  its  employees  and  timely  paid  to  the
                      appropriate  authority proper and accurate amounts for all
                      periods through the date hereof in compliance with all Tax
                      withholding  provisions of all applicable federal,  state,
                      and local laws;

               (iv)   All copies of all  returns  and reports of all Taxes filed
                      by  EdgeAudio  on or prior to the date of this  Agreement,
                      provided or made  available to TSET by  EdgeAudio,  are to
                      the best  knowledge  of  EdgeAudio  and each  Stockholder,
                      complete and accurate; and

               (v)    EdgeAudio has neither  elected nor otherwise  been granted
                      any  preferential  tax  treatment  or  made  any  sort  of
                      commitment  vis-a-vis  any  Tax  authorities,  whether  in
                      connection with a reorganization or otherwise.

     As used in this  Subsection (f), the terms "Tax" and "Taxes" shall mean (A)
     all taxes,  assessments,  levies, imposts, duties, fees,  withholdings,  or
     other similar mandatory  charges,  including,  without  limitation,  income
     taxes,  franchise taxes, transfer taxes or fees, sales taxes, excise taxes,
     ad valorem taxes,  withholding taxes,  minimum taxes,  estimated taxes, and
     social  charges  or  contributions;  and (B) any  interest,  penalties,  or
     additions to tax imposed on a Tax described in clause (A) above, imposed by
     any national,  regional,  local,  or foreign  government or  subdivision or
     agency thereof.

          (g)  CONSENTS.  Except as disclosed in Exhibit 11(g)  attached  hereto

               fashion or as  required by any such  Insurance  Contract so as to

               (iii)  Neither  EdgeAudio  nor any  Stockholder  has received any
                      notice in any form  (including any  citations,  notices of
                      violations,  complaints,  consent  orders,  or  inspection

                      with all such applicable Laws, Judgments, and Permits.

          (u)  CAPITALIZATION.  Exhibit 11(u-1)  attached hereto and made a part
               hereof for all purposes sets forth EdgeAudio's capitalization and
               list of  Stockholders  (showing the name,  mailing  address,  and
               number of EdgeAudio Shares owned by each such  Stockholder) as of
               the date hereof.  All of the Stockholders  have the sole right to
               own the  EdgeAudio  Shares  shown on  Exhibit  11(u-1).  No other
               person has any right or expectancy  to own any EdgeAudio  Shares,
               whether through option, purchase,  grant, or other means by which
               any right or expectancy of ownership could arise or become vested
               in any such person.

          (v)  TAX FREE REORGANIZATION REPRESENTATIONS.  (i) There is no plan or
               intention by the Stockholders of EdgeAudio to sell, exchange,  or
               otherwise  dispose  of a number of TSET  Shares  received  in the
               transaction   that  would  reduce  the  EdgeAudio   Stockholders'
               ownership of TSET stock to a number of shares having a value,  as
               of the date of the  transaction,  of less than 50  percent of the
               value of all of the formerly outstanding stock of EdgeAudio as of
               the same date. Shares of EdgeAudio stock and shares of TSET stock
               held by EdgeAudio  shareholders and otherwise sold, redeemed,  or
               disposed  of  prior  or  subsequent  to the  transaction  will be
               considered in making this representation.

               (ii)   EdgeAudio  has no plan or  intention  to issue  additional
                      shares  of its stock  that  would  result  in TSET  losing
                      control of EdgeAudio  within the meaning of Section 368(c)
                      of the Internal Revenue Code.

               (iii)  At the time of the  transaction,  EdgeAudio  will not have
                      outstanding any warrants, options, convertible securities,
                      or any other  type of right  pursuant  to which any person
                      could  acquire  stock in EdgeAudio  that,  if exercised or
                      converted, would affect TSET's acquisition or retention of
                      control of EdgeAudio,  as defined in Section 368(c) of the
                      Internal Revenue Code.

               (iv)   Neither  EdgeAudio  nor any  Stockholder  is an investment
                      company as defined in Section  368(a)(2)(F)(iii)  and (iv)
                      of the Internal Revenue Code.

               (v)    None of the Stockholders  shall exercise their dissenter's
                      rights in connection with the transaction.

               (vi)   On the date of the  transaction,  the fair market value of
                      the  assets  of  EdgeAudio  will  exceed  the  sum  of its
                      liabilities  plus the  liabilities,  if any,  to which the
                      assets are subject.

<PAGE>

               (vii)  The fair market value of the TSET Shares  received by each
                      EdgeAudio  Stockholder will be approximately  equal to the
                      fair market value of the EdgeAudio  Shares  surrendered in
                      the exchange.

               (viii) Following  the  transaction,  EdgeAudio  will continue its
                      historic  business  or use a  significant  portion  of its
                      historic business assets in a business.

               (ix)   None  of the  compensation  received  by  any  Stockholder
                      employees of EdgeAudio will be separate consideration for,
                      or allocable to, any of their  EdgeAudio  Shares;  none of
                      the TSET Shares received by any Stockholder employees will
                      be  separate  consideration  for,  or  allocable  to,  any
                      employment  agreement;  and the  compensation  paid to any
                      Stockholder   employees  will  be  for  services  actually
                      rendered  and will be  commensurate  with  amounts paid to
                      third  parties  bargaining  at  arm's-length  for  similar
                      services.

     The  representations  and  warranties  contained  in this  Section 11 shall
     survive the  execution  and delivery of this  Agreement for a period of one
     year.

               State of  Nevada  and has all  requisite  power,  authorizations,
               consents,  and approvals necessary to own its assets and carry on
               its  business  as now  being  conducted,  and to  consummate  the
               transactions contemplated herein.

          (b)  NO DEFAULTS OR BREACHES.  Neither the execution of this Agreement
               nor the  performance  of its  obligations  hereunder does or will
               conflict  with or violate  any  provision  of TSET's  articles of
               incorporation or bylaws; violate, conflict with, or result in the
               breach or  termination  of, or  constitute  a  default,  event of
               default (or any event which with notice,  lapse of time, or both,
               would constitute a default or event of default),  under the terms
               of any  material  agreement  to which TSET is a party or by which
               TSET or its securities,  properties,  or businesses are bound; or
               constitute a violation  by TSET of any laws or  judgments  (other
               than any violation,  conflict,  breach, or default that would not
               prevent  TSET from  consummating  the  transactions  contemplated
               herein or otherwise performing its obligations thereunder).

          (c)  ACTIONS   AND   PROCEEDINGS.   There  are  no   actions,   suits,
               proceedings,  or governmental investigations or inquiries pending
               or, to the  knowledge  of TSET,  threatened  against  TSET or its

Page 22
<PAGE>

               properties, assets, operations, or businesses (whether or not the
               defense  thereof or liability with respect  thereto is covered by
               policies  of  insurance)  that might  reasonably  be  expected to
               delay,  prevent,  or hinder the  consummation of the transactions
               contemplated herein.

          (d)  AUTHORITY.  TSET has all necessary  corporate power and authority
               to execute,  deliver, and perform its obligations hereunder;  and
               the  execution,   delivery,  and  performance  by  TSET  of  this
               Agreement has been duly  authorized  by all  necessary  corporate
               action  on its part or is  within  the  authority  of the  person
               executing and delivering the same. This Agreement constitutes the
               legal,  valid,  and  binding  obligations  of  TSET,  enforceable
               against it in accordance with the terms hereof,  except as may be
               limited by applicable bankruptcy, insolvency,  reorganization, or
               other  similar  laws  affecting  creditors'  rights,  and general
               principles of equity.

          (e)  CONSENTS.  Except  as set  forth  in  Exhibit  12(e)  TSET is not
               required to submit any notice,  report,  or other filing with any
               governmental  or  regulatory  authority  in  connection  with the
               execution  and  delivery  by  TSET  of  this  Agreement  and  the
               consummation of the  transactions  contemplated by this Agreement
               and  (2)  no  consent,   approval,   or   authorization   of  any
               governmental  or regulatory  authority is required to be obtained
               by TSET or any  affiliate in  connection  with TSET's  execution,
               delivery,  and performance of this Agreement and the consummation
               of the transactions contemplated by this Agreement.

          (f)  INVESTMENT INTENT. TSET is acquiring the EdgeAudio Shares for its
               own account with the present intention of holding such securities
               for purposes of investment,  and TSET has no intention of selling
               such  securities  in a public  distribution  in  violation of the
               United States  securities laws or any applicable state securities
               laws.  During the course of the  negotiation  of this  Agreement,
               TSET has reviewed all information provided to it by EdgeAudio and
               has had the  opportunity to ask questions of and receive  answers
               from  representatives  of  EdgeAudio  concerning  EdgeAudio,  the
               securities  offered and transferred  hereby, and the transactions
               contemplated herein, and to obtain certain additional information
               requested by TSET.

          (g)  UNREGISTERED  SHARES.  TSET understands that the EdgeAudio Shares
               to be acquired have not been registered  under the Securities Act
               of 1933  as  amended  (the  "Securities  Act"),  by  reason  of a
               specific  exemption  from  the  registration  provisions  of  the
               Securities Act which depends upon,  among other things,  the bona
               fide nature of the investment intent as expressed herein.

          (h)  LEGEND  ON  SHARE   CERTIFICATES.   TSET   understands  that  the
               certificates  for the  Shares  will  bear the  following  legend:
               INTRASTATE  OFFERING  EXEMPTION:  "The shares represented by this

Page 23
<PAGE>

               certificate  have not been registered under the Securities Act of
               1933. No offer,  sale,  transfer,  pledge or other disposition of
               the  shares  may be  effected  in  the  absence  of an  effective
               registration  statement  under  the  Securities  Act of 1933  and
               applicable  state  securities  laws  or  an  opinion  of  counsel
               acceptable  to the  corporation  that  such  registration  is not
               required."

          (i)  NO  BROKERS  OR  FINDERS.  There  are  no  claims  for  brokerage
               commissions, finders' fees, or similar compensation in connection
               with  the   transactions   contemplated   herein   based  on  any
               arrangement  or  agreement  entered into by TSET and binding upon
               the Stockholders.

          (j)  TAX FREE REORGANIZATION REPRESENTATIONS.  (i) TSET has no plan or
               intention to liquidate EdgeAudio; to merge EdgeAudio into another
               corporation;  to cause EdgeAudio to sell or otherwise  dispose of
               any of its assets,  except for dispositions  made in the ordinary
               course of business; or to sell or otherwise dispose of any of the
               EdgeAudio stock acquired in the transaction, except for transfers
               described in Section 368(a)(2)(c) of the Internal Revenue Code.

               (ii)   TSET  has no plan or  intention  to  reacquire  any of its
                      stock issued in the transaction.

               (iii)  No liabilities of EdgeAudio or the EdgeAudio  Stockholders
                      will be assumed by TSET.

               (iv)   TSET  does not own,  directly  or  indirectly,  nor has it
                      owned during the past five years,  directly or indirectly,
                      any stock of EdgeAudio.

               (v)    TSET is not an  investment  company  as defined in Section
                      368(a)(2)(F)(iii) and (iv) of the Internal Revenue Code.

               (vi)   The fair market  value of the TSET stock  received by each
                      EdgeAudio  Stockholder will be approximately  equal to the
                      fair market value of the EdgeAudio  stock  surrendered  in
                      the exchange.

               (vii)  Following  the  transaction,  EdgeAudio  will continue its
                      historic  business  or use a  significant  portion  of its
                      historic business assets in a business.

               (viii) None  of the  compensation  received  by  any  Stockholder
                      employees of EdgeAudio will be separate consideration for,
                      or allocable  to, any of their shares of EdgeAudio  stock;
                      none  of  the  shares  of  TSET  stock   received  by  any
                      Stockholder-employees  will be separate consideration for,
                      or  allocable  to,  any  employment  agreement;   and  the

Page 24
<PAGE>

                      compensation paid to any Stockholder-employees will be for
                      services  actually  rendered and will be commensurate with
                      amounts paid to third  parties  bargaining at arm's length
                      for similar services.

          (k)  PROJECTIONS  AND  FORECASTS.   EdgeAudio  has  provided   certain
               projections and forecasts  (collectively  the "Forecasts") of its
               possible  future  performance to TSET.  TSET hereby  acknowledges
               that the  Forecasts  are  speculative  in  nature,  are  based on
               various  assumptions  that  may or not  come  true,  and  are not
               intended  to  guarantee  in any way  the  future  performance  of
               EdgeAudio.   Notwithstanding   any  other   provisions   of  this
               Agreement,  neither EdgeAudio nor the Shareholders are making any
               representations or warranties  regarding the Forecasts,  and TSET
               agrees  that it has not  relied on and shall not be  entitled  to
               rely on the Forecasts for any purpose.

          (1)  COMPLIANCE WITH PUBLIC INFORMATION REQUIREMENTS OF RULE 144. TSET
               hereby  covenants  that at all times  following  the closing,  it
               shall comply with all public information requirements of SEC Rule
               144 that are  necessary for the  Stockholders  to sell their TSET
               Shares in compliance with Rule 144.

     The representations and warranties  contained in paragraphs (a) through (j)
     of this  Section  12 shall  survive  the  execution  and  delivery  of this
     Agreement  for a period of one year.  The  representations  and  warranties
     contained in paragraph (k) and the covenants  contained in paragraph (l) of
     this Section 12 shall survive the closing indefinitely.

     13.  DISTRIBUTION  OF  PROFITS.   The  parties  agree  that,  as  the  sole
          stockholder of EdgeAudio, TSET shall be entitled on a regular basis to
          distribution  of  all  profits  resulting  from  the  conduct  of  the
          Corporate Business to the extent they exceed the reasonable cash needs
          of  EdgeAudio.  The  directors of EdgeAudio  agree to vote in favor of
          such  distributions (to the extent permitted by law) as requested from
          time to  time by  TSET.  TSET  hereby  covenants  that  it  shall,  in
          connection  with  any  request  for  such  distribution,  ensure  that
          sufficient  cash  remains   allocated  to  EdgeAudio  to  provide  for
          reasonable  operating and working  capital needs for the  continuation
          and  advancement  of  the  Corporate  Business,  funding  of  Programs
          relating to  profit-sharing  or other benefit  plans  according to the
          terms  thereof,   plus  reasonable   reserves  for   contingencies  or
          extraordinary  items.  Until the earlier of the date all the  Earn-out
          Shares have been issued or the date the Earn-out Period  expires,  the
          EdgeAudio board of directors (after consultation with TSET) shall have
          authority  to  determine  the  amount  of  EdgeAudio's  cash  reserves
          necessary for contingencies or extraordinary items.  EdgeAudio's board
          will not unreasonably deny TSET's request for distributions.

     14.  DISPUTE RESOLUTION. All disputes, controversies,  claims, and defenses
          arising out of,  relating to, or  involving  this  Agreement,  whether

Page 25
<PAGE>

          involving theories of tort,  contract,  or violation of statutory laws
          ("Claims") are subject to the following provisions:

          (a)  In the event of any  default  or dispute  between,  breach by, or
               other  controversy  involving,  the parties hereto  regarding the
               subject matter of this Agreement (in any case, a "Dispute"),  the
               parties shall exert their  respective  good faith best efforts to
               amicably  resolve  and  settle  the same.  Toward  this end,  the
               parties shall consult and negotiate with each other in good faith
               to reach a just and equitable solution reasonably satisfactory to
               them.  In the event the Dispute  cannot be amicably  resolved and
               settled  through good faith  negotiations,  the parties  agree to
               resolve the dispute in accordance with the following provisions.

          (b)  Except  as  to  actions,   suits,  or  proceedings  commenced  or
               maintained  by persons not parties  hereto,  the parties agree to
               have any Claim be determined by binding  arbitration.  Unless the
               parties  otherwise  agree in writing,  the  arbitration  shall be
               conducted in Portland,  Oregon before a single  arbitrator and in
               accordance   with  the  commercial   arbitration   rules  of  the
               Arbitration  Service of  Portland.  If the  parties are unable to
               agree  on  an  arbitrator  within  14  days  of  an  election  to
               arbitrate,  the arbitrator  shall be appointed in accordance with
               the  procedures  set forth in ORS 36.320.  The  arbitrator  shall
               issue an award within 30 days of conclusion  of the hearing.  The
               award of the arbitrator  shall be final,  binding and not subject
               to appeal.  Judgment on any  arbitration  award may be entered in
               any court with jurisdiction.

          (c)  If a party  submits  any Claim to  arbitration,  any  provisional
               remedy  issued prior thereto may remain in effect until such time
               as an  arbitrator  is  selected or  appointed  and has assumed to
               determine  the  Claim.   Thereafter  the  arbitrator  may  issue,
               continue,  or terminate  provisional relief or may permit a party
               to pursue provisional relief in court.

          (d)  All actions or suits by a party for provisional remedies shall be
               brought and maintained in Portland,  Oregon.  Each party consents
               to personal jurisdiction in Oregon and waives any right to seek a
               change of venue.

          (e)  The prevailing  party in a judicial  action,  suit or arbitration
               proceeding shall be awarded all reasonable costs, attorneys' fees
               and expenses  incurred in connection  with the  proceeding and on
               any appeal except that the costs and fees of the arbitrator shall
               be shared equally.

          (f)  The arbitrator shall not award or require the payment of, and the
               parties shall not seek,  incidental,  consequential,  or punitive
               damages  except in cases of bad faith  breach of this  Agreement,
               gross negligence, willful misconduct, or fraud. The parties shall
               not seek to delay or prevent the  implementation  of any decision
               of the arbitrator.

          (g)  The parties  acknowledge that,  except as set forth above,  their
               agreement to resolve  Claims  through  arbitration  constitutes a
               waiver of their right to resolve Claims in any court, and that in
               arbitration proceedings the parties may not be entitled to all of
               the rights that would  otherwise  be  available  to them in court
               proceedings.

     15.  INDEMNIFICATION.  (a)  From  and  after  the  date of this  Agreement,
          EdgeAudio and each Stockholder, jointly and severally agree to pay and
          to indemnify fully, hold harmless,  and defend TSET and its directors,
          officers, employees, agents, representatives,  attorneys,  successors,
          and  assigns  from  and  against  any  and all  Liabilities,  damages,
          penalties, Judgments,  assessments, losses, fines, charges, costs, and
          expenses  (including,  but not limited to, reasonable  attorney's fees
          and the costs and expenses of  litigating  any claims)  (collectively,
          "Damages"  incurred  by any of them  arising out of,  relating  to, or
          based upon:

               (i)    any inaccuracy or breach of any representation or warranty
                      of  EdgeAudio or any  Stockholder  set forth in Section 11
                      hereof or elsewhere herein; and

               (ii)   any breach of any  covenant or  agreement  of EdgeAudio or
                      any Stockholder contained in this Agreement.

          TSET's  right to be  indemnified  hereunder  shall not be  limited  or
          affected  by  any  investigation  conducted  or  notice  or  knowledge
          obtained by or on behalf of TSET.

          (b)  From and after the date of this Agreement, TSET agrees to pay and
               to indemnify  fully,  hold harmless,  and defend each Stockholder
               and its directors, officers, employees, agents,  representatives,
               attorneys,  successors,  and assigns from and against any and all
               Damages  incurred by any of them arising out of,  relating to, or
               based upon:

               (i)    any inaccuracy or breach of any representation or warranty
                      of TSET set  forth  in  Section  12  hereof  or  elsewhere
                      herein; and

               (ii)   any breach of any covenant or agreement of TSET  contained
                      in this Agreement.

     A Stockholder's  right to be indemnified  hereunder shall not be limited or
     affected by any investigation  conducted or notice or knowledge obtained by
     or on behalf of any Stockholder.

          (c)  In the  event  that  (A) any  claim,  demand,  or  Proceeding  is
               asserted or instituted by any party other than the parties hereto
               and their  affiliates  which could give rise to Damages for which
               an indemnified party intends to seek indemnification hereunder (a
               "Third Party Claim"), or (B) an indemnified party intends to make
               a claim to be  indemnified  hereunder  which  does not  involve a
               Third Party Claim (a "Direct Claim"), the indemnified party shall
               promptly,  within  21 days of the date on which it first  becomes
               aware of the  existence of a Third Party Claim or a Direct Claim,
               send  written  notice  to  the  indemnifying   party  or  parties
               specifying  the nature of such Third Party Claim or Direct  Claim

Page 27
<PAGE>

               and the amount  thereof (or a good faith estimate of such amount,
               which  estimate  shall  not be  conclusive  of any  final  amount
               thereof) (a "Claim Notice");  provided,  however, that failure to
               provide  a Claim  Notice  shall  not  constitute  any  waiver  or
               relinquishment    of   the   indemnified    party's   rights   to
               indemnification hereunder.

          (d)  In the event of a Third Party Claim,  the  indemnified  party may
               participate,  at its own  expense,  in the defense  thereof  with
               legal  counsel of its own  choice  reasonably  acceptable  to the
               indemnifying  party or parties.  Unless the indemnifying party or
               parties  shall have agreed in writing that any and all Damages to
               the  indemnified  party  are  fully  covered  by the  indemnities
               provided herein,  no Third Party Claim may be settled without the
               indemnified party or parties' prior written consent.

          (e)  In the event of a Direct  Claim,  unless the  indemnifying  party
               notifies the indemnified  party within 30 days after receipt of a
               Claim Notice that they dispute such Direct  Claim,  the amount of
               such Direct Claim shall be conclusively deemed a liability of the
               indemnifying   party  or  parties   and  shall  be  paid  to  the
               indemnified  party or  parties  no later  than 10 days  following
               lapse of such 30-day period.

     16.  GENERAL  PROVISIONS.  (a)  INTEGRATION  AND AMENDMENT.  This Agreement
          constitutes  the entire  agreement  between and among the parties with
          respect  to  the  subject  matter  hereof  and  supersedes  all  prior
          agreements  and   understandings   with  respect  thereto.   No  other
          agreement,  whether  oral or  written,  shall  be used  to  modify  or
          contradict the provisions hereof unless the same is in writing, signed
          by the parties, and states that it is intended to amend the provisions
          of this Agreement.

          (b)  COUNTERPARTS.   This   Agreement  may  be  executed  in  multiple
               counterparts  (and by  facsimile  signature,  to be  followed  by
               manual signature as soon as practicable),  each of which shall be
               deemed  an  original,  and  all  of  which  shall  be  deemed  to
               constitute  a  single   agreement,   document,   instrument,   or
               certificate, as the case may be.

          (c)  BINDING EFFECT. This Agreement shall be binding upon and inure to
               the benefit of the heirs,  successors,  and permitted  assigns of
               the parties hereto.

          (d)  WAIVER. No failure by any party to this Agreement to exercise, no
               delay in  exercising,  and no course of dealing  with respect to,
               any right,  power, or privilege  hereunder or any other document,
               instrument,  or certificate  relating hereto,  shall operate as a
               waiver  or any  relinquishment  for the  future  thereof;  and no
               single or partial  exercise  of any right,  power,  or  privilege
               hereunder  or any  other  document,  instrument,  or  certificate
               relating  hereto  shall  preclude  any other or  future  exercise
               thereof or the exercise of any other right, power, or privilege.

          (e)  SEVERABILITY.  If any  provision  (or  portion  thereof)  of this
               Agreement  is  adjudged  illegal or  unenforceable  by a court of
               competent   jurisdiction,    the   remaining   provisions   shall
               nevertheless continue in full force and effect. In any such case,
               the provision deemed illegal or unenforceable  shall be remade or
               interpreted by the parties in a manner that such provision  shall
               be enforceable to preserve,  to the maximum extent possible,  the
               original intention and meaning thereof.

          (f)  NOTICES.  All  notices  or  other  communications  given  or made
               hereunder shall be in writing and may be delivered personally, by

Cancer Detection International, LLC
C/o Victor Weisser, Esq.
799 Hummingbird Court
El Cajon, CA  92019-2768

Gentlemen:

         This letter will  constitute the  undertaking  of TSET,  Inc., a Nevada
corporation ("TSET"), to acquire all of the equity ownership interests (the "CDI
Interests") of Cancer Detection  International,  LLC, a Nevada limited liability
company ("CDI"). TSET shall acquire all of the CDI Interests,  free and clear of
any and all liens, claims,  encumbrances,  options, rights of any third parties,
and  restrictions  of any kind  whatsoever,  in exchange  for 180,000  shares of
TSET's  common  stock,  par value  $0.001 per share (the "TSET  Shares"),  to be
allocated among CDI's equity holders (the "Equity  Holders")  according to their
pro rata  interests  therein,  to be set forth in writing  provided to TSET. The
TSET Shares shall constitute the sole compensation to the Equity Holders for the
CDI  Interests.  The Equity  Holders  understand  that the TSET Shares  shall be
subject to all of the  restrictions,  conditions,  and limitations  noted on the
certificates  representing  the same,  and each Equity  Holder  agrees to comply
therewith at all times.  CDI's current  management will continue in place and be
responsible for CDI's day-to-day business operations,  subject to such strategic
direction  as may be  provided  by TSET  from  time to time.  TSET,  at its sole
option, shall be entitled to appoint representatives to CDI's board of directors
proportionate  to TSET's  ownership  interest in CDI,  and in no case shall have
less than one representative on CDI's board of directors.

         The parties agree that more detailed,  definitive  legal  documentation
(collectively,  the  "Definitive  Agreements")  will be completed  and signed by
them;  however,  the  parties  intend  that  this  letter  constitute  the basic
agreement  between them for the  acquisition of CDI  contemplated  hereby,  upon
which  the  Definitive  Agreements  shall  be  based,  until  such  time  as the
Definitive  Agreements are completed and signed.  In connection with preparation
and negotiation of specific provisions of the Definitive Agreements, the parties
agree to fully and  amicably  cooperate,  act in good  faith,  and  exert  their
respective  best  efforts  to  enable  the  execution  thereof  at the  earliest
practicable date. The parties agree that the Definitive Agreements shall contain
customary terms, conditions,  and undertakings,  including,  without limitation,
customary and appropriate  representations  and warranties to be made by CDI and
each Equity Holder, and indemnification provisions in favor of TSET.

         CDI has  represented  to TSET,  among other things,  and in addition to
those representations and warranties to be made by CDI and each Equity Holder in
the  Definitive  Agreements,  that (a) it engages in the business of  performing
state-of-the-art  blood  laboratory  analysis  for the very early  detection  of
cancer  (the  "Blood  Analysis"),   through  the  identification  and  level  of
anti-malignin  antibodies;  (b) the Blood  Analysis  can detect very early stage
cancers  with a high degree of  reliability;  (c) CDI has all  requisite  right,

<PAGE>

Cancer Detection International, LLC
May 4, 2000
Page 2

title,  and interest in, and authority to perform,  the Blood Analysis,  without
infringement upon the intellectual  property or other proprietary  rights of any
other person;  (d) CDI has conducted  business  operations to date in compliance
with  all  applicable  legal  requirements;  (e) any and all  consents  of third
parties required for the consummation of the  transactions  contemplated  herein
and in the Definitive Agreements have been obtained; (f) no broker's or finder's
fees are payable to any person in connection with the transactions  contemplated
herein and in the  Definitive  Agreements;  (g) CDI and each Equity  Holder have
full legal  authority  and  capacity to execute and deliver  this letter and the
Definitive  Agreements and perform all obligations contained herein and therein;
and  (h)  there  are  no  litigation  or  other  administrative,   arbitral,  or
alternative dispute resolution  proceedings pending or threatened against CDI or
any Equity Holder seeking to restrain or prohibit in any manner the transactions
contemplated  herein  and  in  the  Definitive  Agreements,  nor  is  there  any
outstanding  judgment  against CDI or any Equity Holder having such effect.  CDI
hereby  agrees that it shall  continue to conduct its business in  substantially
the same manner as heretofore  conducted and incur no financial  liabilities  or
commit for the  expenditure  of any of the Working  Capital  (as defined  below)
without TSET's prior written consent.

         TSET shall provide to CDI working  capital in the  aggregate  amount of
$350,000  (the  "Working  Capital")  to  enable  CDI  to,  among  other  things,
effectively  market  and pay the  costs  associated  with  performing  the Blood
Analysis.  The Working  Capital shall be provided in such increments as TSET and
CDI may agree,  pursuant to a budget and disbursement schedule to be established
by them, with the administration of the Working Capital to be performed by TSET.
The parties agree that some initial  number of the Blood  Analysis,  which costs
approximately $300 each, will be offered free of charge to prospective  patients
in the Palm Springs, California area.

         As the  sole  owner  of CDI,  any and all  profits  resulting  from the
conduct of CDI's  business  shall belong to TSET,  and TSET shall be entitled to
distribution  thereof from time to time;  however,  the parties  understand that
CDI's main value will  derive from using the Blood  Analysis  to identify  early
stage cancers and then refer  patients to such cancer  diagnostic  and treatment
centers as may be established by TSET through another entity.  Accordingly,  the
parties do not anticipate  significant,  if any, initial profits to be generated
by CDI.

         Any disputes  arising out of this letter or the  Definitive  Agreements
shall be resolved through arbitration rather than litigation, to the extent such
disputes cannot be resolved amicably through good faith efforts. All arbitration
proceedings shall take place in Clackamas  County,  Oregon and shall be governed
by the rules of the American Arbitration  Association applicable to contracts of
this type. The final decision of the arbitrator  shall be final and binding upon
the parties and shall be  enforceable  in any court of  competent  jurisdiction;
provided, however, that the arbitrator shall not award or require the payment of
incidental,  consequential,  or  punitive  damages  except in cases of bad faith
breach  of this  letter  or the  Definitive  Agreements  or  instances  of gross
negligence  or willful  misconduct.  No party shall seek to delay or prevent the
implementation of any arbitral decision. The prevailing party in any arbitration
proceeding shall be entitled to recover  reasonable  attorney's fees and related
costs and  expenses  of the  arbitration.  The  parties  acknowledge  that their

<PAGE>

Page 3

agreement to resolve disputes through arbitration  constitutes a waiver of their
right  to  resolve  disputes  in any  court  through  litigation,  and  that  in
arbitration  proceedings  the  parties  may not be entitled to all of the rights
that would otherwise be available to them in court proceedings.

         This letter and the  Definitive  Agreements may be executed in multiple
counterparts (and by facsimile signature, with manual signatures to be exchanged
as soon as practicable  thereafter),  each of which shall be deemed an original,
and all of which shall be deemed to constitute a single  agreement.  The parties
agree that the  Definitive  Agreements  shall  supersede  this letter upon their
execution and delivery;  however,  no other agreement,  whether oral or written,
shall be used to modify or contradict the written  agreements of the parties set
forth herein and in the  Definitive  Agreements.  No amendment of this letter or
the Definitive Agreements shall be valid and binding upon the parties unless the
same is in writing and signed by the parties.

         This letter shall be governed by and construed in  accordance  with the
laws of the State of Oregon, exclusive of its conflicts of laws rules.

         Your  signature,  in the space  provided  below,  shall  evidence  your
acceptance and agreement to this letter,  which shall continue in full force and
effect until superseded by the Definitive Agreements.  Please sign both enclosed
copies of this letter and return one fully signed copy to TSET by return express
delivery.

                                            Sincerely,

                                            Jeffrey D. Wilson
                                            Chairman and Chief Executive Officer
