                             STOCK OPTION AGREEMENT
                             ----------------------

      THIS STOCK OPTION  AGREEMENT is entered into as of April 9, 2001, by and
between  TSET,  Inc.,  a  Nevada  corporation  ("TSET"),  and  Erik  W.  Black
("Black").

                                   WITNESSETH:
                                   ----------

      WHEREAS,  TSET desires to grant to Black an option to acquire up to 50,000
restricted  shares of TSET's  common  stock,  par value  $0.001  per share  (the
"Option Shares"),  in consideration of valuable  contributions  made by Black to
TSET and its wholly-owned subsidiaries; and

      WHEREAS, Black desires to accept such option.

      NOW,  THEREFORE,  for and in  consideration  of the  premises  and  mutual
promises,  covenants,  and  agreements  set forth  herein and for other good and
valuable  consideration,  the delivery,  receipt,  and  sufficiency  of which is
hereby acknowledged, the parties hereto agree as follows:

      1.   GRANT OF OPTION. TSET hereby grants to Black an option (the "Option")
           to acquire the Option Shares at an exercise price of $0.885 per share
           (the "Exercise  Price").  The Option shall immediately and fully vest
           in Black's favor for all purposes upon execution and delivery of this
           Agreement by the parties.  The Option is personal to Black and may be
           exercised  only by  Black  during  his  lifetime.  The  Option  shall
           continue  in full  force and  effect for a period of 5 years from the
           date hereof (the  "Term"),  at which time the Option shall expire and
           terminate unless previously  exercised by Black. The Option shall not
           be subject to forfeiture or  termination,  except for Black's failure
           to exercise the Option during the Term.

      2.   EXERCISE OF OPTION. The Option may be exercised by Black, in whole or
           in part,  at any time during the Term upon receipt by TSET of written
           notice from Black (the "Exercise Notice").  The Exercise Notice shall
           specify the number of Option Shares Black desires to acquire pursuant
           thereto and provide any necessary or appropriate instructions to TSET
           and its transfer agent  regarding the  denomination  of  certificates
           representing  the  Option  Shares  and the name in which  the  Option
           Shares should be registered. The exercise of the Option shall be on a
           "cashless" basis and Black shall not be required to remit to TSET any
           payment therefor.

      3.   RESERVATION  OF THE  OPTION  SHARES.  The ensure  fulfillment  of its
           obligations hereunder should Black elect to exercise the Option, TSET
           shall reserve from its authorized but unissued capital that number of
           shares of its common stock equal to the Option Shares.

      4.   RESTRICTIONS ON TRANSFER.  Black  acknowledges that the Option Shares
           are  subject to certain  restrictions  upon  transfer,  and cannot be
           sold, assigned,  transferred, or conveyed (in any case, a "transfer")
           except in compliance with such restrictions and applicable provisions
           of federal and state securities laws.  Certificates  representing the






           Option Shares shall bear appropriate restrictive legends and notices.
           In the event Black desires to transfer any Option Shares prior to the
           expiration  of such  restrictions,  TSET shall be entitled to receive
           from Black written undertakings, certifications, or opinions of legal
           counsel evidencing compliance with such restrictions.

      5.   TAX MATTERS.  Black  acknowledges  that treatment of the Option,  the
           Option Shares,  and events or transactions with respect thereto,  for
           federal and state income and other tax  purposes,  is dependent  upon
           various   factors  and  events  which  are  not  determined  by  this
           Agreement.  TSET makes no  representations  to Black with respect to,
           and  hereby  disclaims  any and  all  responsibility  as to such  tax
           treatment.  Black  shall be  solely  and  fully  responsible  for the
           payment  of, and shall pay,  any and all  federal,  state,  and other
           taxes  (including any and all withholding  taxes) levied with respect
           to the grant of the Option,  the purchase of the Option  Shares,  and
           any  subsequent  transfer  thereof.  In the event the exercise of the
           Option or the disposition of the Option Shares following  exercise of
           the  Option  results  in  Black's  realization  of  income  which for
           federal,  state,  local,  or other  income tax purposes is, in TSET's
           opinion,  subject to withholding of tax, then at the election of TSET
           and prior to the delivery to Black of certificates  representing  the
           Option  Shares  acquired by him pursuant to an Exercise  Notice,  (a)
           Black shall pay to TSET an amount  equal to such  withholding  tax or
           (b) TSET may  withhold  such  amount from any  compensation  or other
           payments owed by TSET to Black.

      6.   NONQUALIFIED  STATUS.  The Option is not intended to be an "incentive
           stock  option" as defined in the Internal  Revenue  Code of 1986,  as
           amended,  and shall not be  treated as such  whether  or not,  by the
           terms hereof, it meets the requirements of any applicable  provisions
           thereof.

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

           mail (return receipt requested), postage and fees prepaid.

      8.   INTEGRATION, AMENDMENT, AND WAIVER. When executed and delivered, this
           Agreement shall constitute the entire  agreement  between the parties
           with respect to the subject matter hereof and shall supersede any and
           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. No waiver by either party of any breach
           of this  Agreement  in any  particular  instance  shall  constitute a
           waiver of any other breach  hereof in any other  circumstance  or any
           relinquishment  for the future of their respective rights to strictly
           enforce all of the other provisions hereof or seek all remedies which
           may be available at law or in equity.

      9.   COUNTERPARTS;  BINDING  EFFECT.  This  Agreement  may be  executed in
           multiple counterparts (and by facsimile signature,  to be followed by
           manual signature), each of which shall be deemed an original, and all
           of which  shall be  deemed to  constitute  a single  agreement.  This
           Agreement  shall be  binding  upon and  inure to the  benefit  of the
           parties' respective permitted heirs, successors, and assigns.

      10.  ASSIGNMENT.  This  Agreement  is  personal  to  the  parties  hereto.
           Accordingly,  Black  shall not  assign  or  transfer  this  Agreement
           without the prior written consent of TSET, which consent shall not be
           unreasonably withheld,  conditioned,  or delayed; provided,  however,
           that Black shall be permitted to assign or transfer this Agreement to
           a legal entity owned by Black  without such  consent.  Any  attempted
           assignment of this Agreement by Black without receipt of such consent
           from TSET shall be null and void.

      11.  SEVERABILITY. If any provision (or portion thereof) of this Agreement
           is adjudged unenforceable by a court of competent  jurisdiction,  the
           remaining  provisions shall  nevertheless  continue in full force and
           effect  and the  provision  deemed  unenforceable  shall be remade or
           interpreted by the parties in a manner that such provisions  shall be
           enforceable to preserve, to the maximum extent possible, the original
           intention  and meaning  thereof.  If necessary to effect such intent,
           TSET and Black shall  negotiate in good faith to amend this Agreement
           to replace such provision with language believed in good faith by the
           parties to be enforceable, which as closely as possible reflects such
           intent.

      12.  NO THIRD PARTY BENEFICIARIES.  This Agreement is for the sole benefit
           of the parties and their permitted  successors,  heirs,  and assigns.
           Nothing herein,  expressed or implied,  shall give or be construed to
           give any other  person,  other than the parties  and their  permitted


                                       19



           assigns,  any legal or  equitable  rights  hereunder.  No finder's or
           other  fees shall be  payable  by either  party  with  respect to the
           exercise of the Option or the issuance of the Option Shares  pursuant
           to this Agreement.

      13.  STATE  SECURITIES  QUALIFICATIONS.  The  sale  of the  Option  Shares
           pursuant to any  exercise of the Option has not been  qualified  with
           the  securities   regulatory   authorities  in  any  state  or  other
           jurisdiction  and the  issuance  of the Option  Shares  prior to such
           qualification  may be unlawful  unless such  transactions  are exempt
           from such  qualification  requirements.  The  rights  of the  parties
           hereto  are  expressly  conditioned  upon  such  qualification  being
           obtained, unless any such transaction is so exempt.

      14.  GOVERNING LAW. This  Agreement  shall be governed by and construed in
           accordance  with the laws of the State of  Oregon,  exclusive  of its
           conflicts of laws principles.

      IN WITNESS WHEREOF, the parties have executed and delivered this Agreement
effective as of the date first written above.

TSET, Inc.
