         owned,  leased and  operated and (b) carry on its business as currently
         conducted and as proposed to be conducted. Tower Tech is duly qualified
         or licensed to do business in each jurisdiction in which the failure to

         business, operations,  properties,  assets, liabilities,  prospects, or

         "MATERIAL EFFECT").

3.3      SUBSIDIARIES AND AFFILIATES.  Tower Tech does not own or hold, directly
         or  indirectly,  any equity,  debt, or other  interest in any entity or
         business or any option to acquire any such interest.

3.4      OPTIONS OR OTHER RIGHTS. No options,  warrants,  calls,  commitments or
         other rights to acquire, sell or issue shares of capital stock or other
         equity  interests  of Tower  Tech,  whether  upon  conversion  of other
         securities or  otherwise,  are issued or  outstanding,  and there is no
         agreement or  understanding  with respect to the voting of such capital
         stock or other equity interests.

3.5      OWNERSHIP OF SHARES. The shares of Tower Tech Common Stock are owned of
         record and beneficially by the Tower Tech  Shareholders as set forth on
         Schedule A. The Tower Tech  Shareholders  possess  full  authority  and
         legal  right to  sell,  transfer,  and  assign  the  entire  legal  and
         beneficial  ownership  of the shares of Tower Tech Common  Stock,  free
         from all liens,  claims, and encumbrances of any kind; and there are no
         outstanding   rights  or   obligations   granted   by  the  Tower  Tech
         Shareholders  to  purchase  or acquire  any of the shares of Tower Tech
         Common  Stock or any interest in any of the shares of Tower Tech Common
         Stock.  Upon  transfer  of the  shares of Tower  Tech  Common  Stock to
         Blackfoot  hereunder at the Closing,  Blackfoot will receive the entire
         legal and beneficial interest in the shares of Tower Tech Common Stock,
         free and clear of all liens, claims, and encumbrances and subject to no
         legal or equitable restrictions of any kind.

3.6      VALIDITY  AND   EXECUTION  OF   AGREEMENT.   Each  of  the  Tower  Tech
         Shareholders  has the full legal right,  capacity and power required to
         enter into,  execute and deliver  this  Agreement  and to carry out the
         transactions  contemplated.  This  Agreement has been duly executed and
         delivered by each of the Tower Tech  Shareholders  and  constitutes the
         valid and binding  obligation  of each of the Tower Tech  Shareholders,
         enforceable in accordance with its terms,  subject to the qualification
         that  enforcement of the rights and remedies  created hereby is subject
         to (a)  bankruptcy,  insolvency,  reorganization,  moratorium and other
         laws of  general  application  affecting  the rights  and  remedies  of
         creditors and (b) general  principles of equity  (regardless of whether
         such enforcement is considered in a proceeding in equity or at law).

3.7      NO CONFLICT.  None of the execution,  delivery,  or performance of this
         Agreement  does or will:  (a) result in any violation or be in conflict
         with or  constitute  a  default  under  any  term or  provision  of the

                  affiliates,  associates,  officers,  or  directors  seeking to
                  restrain,  prevent,  or change  in any  material  respect  the
                  transactions   contemplated   hereby  or  seeking  damages  in
                  connection  with  such   transactions  that  are  material  to
                  Blackfoot.

         (h)      The  Blackfoot  Common  Stock shall be approved for listing on
                  the OTC Bulletin Board.

         (i)      Blackfoot shall satisfy (i) the filing  requirements set forth
                  in Section 13 of the Exchange Act and (ii) the requirements of

         (j)      At  Closing,  all but  one  member  of  Blackfoot's  Board  of

                  such  change  in  the  composition  of  Blackfoot's  Board  of
                  Directors,  Blackfoot,  at or  prior  to  Closing  shall  have
                  complied  with  the  requirements  of  Section  14(f)  of  the
                  Exchange Act and Rule 14f-1 promulgated thereunder;  PROVIDED,
                  that Blackfoot's obligation to effect such -------- compliance
                  shall  be  contingent   upon  the  Tower  Tech   Shareholders'
                  furnishing to Blackfoot such information with respect to their
                  nominees to  Blackfoot's  Board of Directors as is required by
                  the  applicable  provisions  of the Exchange Act and the rules
                  and  regulations  promulgated  thereunder for compliance  with
                  Section 14(f) thereof.

         (k)      Blackfoot  shall have changed its name to "Tower Tech Systems,

                  Articles of  Incorporation  with the Secretary of State of the

                  10,000,000 shares of preferred stock, $0.001 par value.

                                   ARTICLE VII
                             POST-CLOSING COVENANTS

The parties covenant to take the following actions after the Closing Date:

7.1      FURTHER INFORMATION.  Following the Closing,  each party will afford to
         the  other  party,  its  counsel  and its  accountants,  during  normal
         business hours,  reasonable access to the books, records and other data
         of  Tower  Tech or  Blackfoot,  as the  case  may be,  relating  to the
         business of Tower Tech or Blackfoot in their possession with respect to
         periods  prior to the Closing and the right to make copies and extracts
         therefrom, to the extent that such access may be reasonably required by
         the requesting  party (a) to facilitate the  investigation,  litigation
         and final  disposition of any claims which may have been or may be made
         against any party or its  affiliates  and (b) for any other  reasonable
         business purpose.

7.2      RECORD RETENTION.  Each party agrees that for a period of not less than
         five years  following the Closing Date, such party shall not destroy or
         otherwise  dispose  of any of the Books and  Records  of Tower  Tech or
         Blackfoot relating to the business of Tower Tech or Blackfoot in his or
         its possession  with respect to periods prior to the Closing Date. Each
         party  shall  have the right to  destroy  all or part of such Books and
         Records  after  the fifth  anniversary  of the  Closing  Date or, at an
         earlier  time by giving each other party  hereto 30 days prior  written
         notice of such intended  disposition  and by offering to deliver to the
         other  party or  parties,  at the other  party's or  parties'  expense,
         custody of such Books and Records as such party may intend to destroy.

7.3      POST-CLOSING  ASSISTANCE.  The Tower Tech Shareholders on the one hand,
         and  Blackfoot,  on the other hand,  will  provide each other with such
         assistance  as may  reasonably  be  requested  in  connection  with the
         preparation  of any Tax Return,  any audit or other  examination by any
         taxing  authority,  or  any  judicial  or  administrative   proceedings
         relating to liability  for Taxes,  and each will retain and provide the
         requesting party with any records or information that may be reasonably
         relevant  to  such  return,   audit  or  examination,   proceedings  or
         determination.  The party  requesting  assistance  shall  reimburse the
         other party for reasonable out-of-pocket expenses incurred in providing
         such assistance.  Any information obtained pursuant to this SECTION 7.3
         or pursuant to any other  Section  hereof  providing for the sharing of
         information or the review of any Tax Return or other schedule  relating
         to Taxes shall be kept confidential by the parties hereto.

7.4      SEC REPORTING.  With a view to making available the benefits of certain
         rules and  regulations of the SEC which may at any time permit the sale
         of the Blackfoot Common Stock to the public without registration,  from
         and after the Closing, the new management of Blackfoot will:

                  at all times; and

         (b)      file with the SEC in a timely  manner  all  reports  and other
                  documents required of Blackfoot under the Exchange Act.

                  or prior to the close of business on December 31, 2005 (unless
                  such event has been  caused by a breach of this  Agreement  by
                  the party seeking such termination);

         (c)      by  Blackfoot  or by all of the Tower Tech  Shareholders  if a
                  Governmental or Regulatory  Body has  permanently  enjoined or
                  prohibited  consummation  of the Share Exchange and such court
                  or government action is final and nonappealable;

         (d)      by  Blackfoot  if the Tower Tech  Shareholders  have failed to

                  agreements  under  this  Agreement  that  are  required  to be
                  complied with prior to the date of such termination; or

         (e)      by the Tower  Tech  Shareholders  if  Blackfoot  has failed to
                  comply in any material  respect  with any of its  covenants or
                  agreements  under  this  Agreement  that  are  required  to be
                  complied with prior to the date of such termination.

8.2      SURVIVAL AFTER TERMINATION. If this Agreement is terminated pursuant to
         Section  8.1, (a) this  Agreement  shall become null and void and of no
         further  force and  effect,  except for the  provisions  of SECTION 5.1
         relating to the obligation to keep confidential certain information and
         (b) there shall be no  liability on the part of Tower Tech or Blackfoot
         or their respective affiliates.

                                   ARTICLE IX

         the Tower  Tech  Shareholders  will  execute  and  deliver  such  other
         instruments of sale, transfer, conveyance,  assignment and confirmation
         and take such other action as Blackfoot may  reasonably  deem necessary
         or  desirable  in order to  transfer,  convey  and assign the Shares to
         Blackfoot and to assist Blackfoot in exercising all rights with respect
         thereto.  The parties shall use their best efforts to fulfill or obtain
         the  fulfillment of the conditions to the Closing,  including,  without
         limitation, the execution and delivery of any document or other papers,
         the  execution  and delivery of which are  conditions  precedent to the

                           Los Angeles, California 90067

9.4      ARBITRATION.  Any  dispute,  controversy,  or  claim  arising  out  of,
         relating to, or in connection with, this Agreement or the agreements or
         transactions contemplated by this Agreement shall be finally settled by
         binding  arbitration.  The  arbitration  shall  be  conducted  and  the
         arbitrator   chosen  in  accordance  with  the  rule  of  the  American
         Arbitration  Association  in  effect  at the  time of the  arbitration,
         except  as they  may be  modified  herein  or by  mutual  agreement  of
         Blackfoot and the Tower Tech Shareholders.  In connection with any such
         arbitration,  each party shall be afforded the  opportunity  to conduct
         discovery in accordance with the Federal Rules of Civil Procedure.






         (a)      The  seat of the  arbitration  shall be in  Manitowoc  County,
                  Wisconsin,  and will  follow  the  format  known as  "Baseball
                  Arbitration".   Each  of  the  Tower  Tech   Shareholders  and
                  Blackfoot  hereby  irrevocably  submits to the jurisdiction of
                  the arbitrator in Manitowoc County,  Wisconsin, and waives any
                  defense in an arbitration based upon any claim that such party
                  is  not  subject   personally  to  the  jurisdiction  of  such
                  arbitrator,   that  such   arbitration   is   brought   in  an
                  inconvenient format, or that such venue is improper.

         (b)      The arbitral  award shall be in writing and shall be final and
                  binding on each of the  parties to this  Agreement.  The award
                  may include an award of costs, including reasonable attorneys'
                  fees and disbursements. Judgment upon the award may be entered
                  by  any   court   having   jurisdiction   thereof   or  having
                  jurisdiction  over the  parties or their  assets.  Each of the
                  Tower Tech Shareholders and Blackfoot  acknowledges and agrees
                  that by agreeing to these  arbitration  provisions each of the
                  parties  hereto is waiving  any right that such party may have
                  to a jury trial with respect to the  resolution of any dispute
                  under  this  Agreement  or  the  agreements  or   transactions
                  contemplated hereby.

9.5      PUBLICITY.   No  publicity  release  or  announcement  concerning  this
         Agreement or the transactions contemplated hereby shall be made without
         advance approval  thereof by Blackfoot and the Tower Tech  Shareholders
         except as may be required by applicable law.

9.6      ENTIRE AGREEMENT. This Agreement (including the Exhibits and Schedules)
         and the agreements, certificates and other documents delivered pursuant
         to this Agreement  contain the entire  agreement among the parties with
         respect to the transactions  described herein,  and supersede all prior

         canceled, renewed or extended, and the terms hereof may be waived, only
         by a  written  instrument  signed by the  parties  or, in the case of a
         waiver,  by the party waiving  compliance.  No delay on the part of any
         party in  exercising  any right,  power or  privilege  hereunder  shall
         operate as a waiver thereof

                       Share Exchange Agreement - Page 25

         accordance  with  the  laws  of  the  State of Nevada without regard to
         principles of conflicts of law.

9.9      BINDING EFFECT, NO ASSIGNMENT. This Agreement shall be binding upon and
         inure to the benefit of the parties and their respective successors and
         permitted assigns. This Agreement is not assignable by any party hereto
         without the prior written consent of the other parties hereto except by
         operation of law and any other purported  assignment  shall be null and
         void.

9.10     COUNTERPARTS.  This  Agreement may be executed by the parties hereto in
         separate  counterparts,  each of which when so executed  and  delivered
         shall  be  an  original,  but  all  such  counterparts  shall  together
         constitute one and the same instrument. Each counterpart may consist of
         a number of copies  hereof each signed by less than all,  but  together
         signed by all of the parties hereto.

9.11     EXHIBITS AND  SCHEDULES.  The Exhibits and Schedules are a part of this
         Agreement  as if fully  set  forth  herein.  All  references  herein to
         Sections, subsections,  clauses, Exhibits and Schedules shall be deemed
         references  to such parts of this  Agreement,  unless the context shall
         otherwise require.

9.12     EFFECT OF DISCLOSURE ON SCHEDULES.  Any item  disclosed on any Schedule

         provision of this Agreement or the application of such provision or any
         portion thereof to any person or circumstance, shall be held invalid or
         unenforceable,   the  remaining  portion  of  such  provision  and  the
         remaining  provisions of this  Agreement,  or the  application  of such
         provision  or  portion  of  such   provision  as  is  held  invalid  or
         unenforceable to persons or circumstances  other than those as to which
