       This Consulting Services Agreement (the "Agreement") is entered into this
29th day of May,  2003 by and between  Stanton,  Walker & Company,  a New Jersey
corporation (hereinafter referred to as, "Consultant"),  and National Scientific
Corporation.  (OTCBB:  NSCT)  (hereinafter  referred to as,  "Client"),  a Texas
corporation,  (collectively  referred to as the "Parties") with reference to the
following:

                              PRELIMINARY STATEMENT

The  Client  desires  to be  assured  of the  association  and  services  of the
Consultant  in order to avail  itself of the  Consultant's  experience,  skills,
abilities,   knowledge,  and  background  to  facilitate  long  range  strategic
planning,   and  to  advise  the  Client  in  business   and/or   financial  and
merger/acquisition  matters and is therefore  willing to engage  Consultant upon
the terms and conditions set forth herein. Consultant desires to be assured, and
Client desires to assure Consultant,  that, if Consultant associates with Client
and  allocates  its  resources  necessary  to provide  Client with its  business
advisory and  consulting  services,  Consultant  will be paid the  consideration
described herein and said consideration will be nonrefundable, regardless of the
circumstances  unless it shall be determined through binding  arbitration as set
forth in Section 6 hereafter  that the  Consultant  willfully and  intentionally
committed fraud or gross negligence in connection with this Agreement.

Consultant  agrees to be engaged  and  retained by Client and upon the terms and
conditions set forth herein.

NOW,  THEREFORE,  in  consideration  of the  foregoing,  of the mutual  promises
hereinafter set forth and for other good and valuable consideration, the receipt
and  sufficiency of which are hereby  acknowledged,  the Parties hereto agree as
follows:

ENGAGEMENT.  Client hereby  engages  Consultant on a  non-exclusive  basis,  and
Consultant  hereby  accepts the  engagement  and its  associated  Engagement Fee
("Engagement Fee") described Section 2 below, to become a business and financial
Consultant to Client and to render such advice,  consultation,  information, and
services to the Directors and/or Officers of Client regarding  general financial
and business matters including, but not limited to the following:

1.1  ADVICE AND COUNSEL.  Consultant  will provide advice and counsel  regarding
     Client's strategic business plans, strategy and negotiations with potential
     business  strategic  partnering,  corporate  planning and or other  general
     business consulting needs as expressed by Client.

1.2  CLIENT AND/OR CLIENT'S AFFILIATE TRANSACTION DUE DILIGENCE. Consultant will
     participate and assist Client in the due diligence process, where possible,
     on all proposed financial transactions affecting Client of which Consultant
     is notified in writing in advance,  including  conducting  investigation of

<PAGE>

Consulting Services Agreement                                       Page 2 of 10

     and  providing   advice  on  the  financial,   valuation  and  stock  price
     implications of the proposed transaction(s).

1.3  ANCILLARY  DOCUMENT  SERVICES.  If  necessary,  Consultant  will assist and
     cooperate  with Client in the  development,  editing and production of such
     documents as are reasonably  necessary to assist in any transaction covered
     by this Agreement. However, this Agreement will not include the preparation
     or procuring of legal documents or those documents  normally prepared by an
     attorney.

1.4  MERGERS AND ACQUISITIONS.  Consultant will provide assistance to Client, as
     mutually  agreed,  in  identifying  merger and/or  acquisition  candidates,
     assisting in any due diligence process,  recommending transaction terms and
     providing  advice and  assistance  during  negotiations,  as needed.  It is
     expressly  understood that Consultant shall have no power to bind Client to
     any  contract  or  transaction   obligation.   Additional  compensation  to
     Consultant  for the  successful  closing of any such merger or  acquisition
     shall be made pursuant to Section 1.4.a.ii. below:

     a.   MERGERS AND ACQUISITIONS. Consultant agrees to introduce and/or assist
          Client in  acquiring,  merging,  and/or  divesting on a  non-exclusive
          basis,  from time to time, as Consultant deems appropriate in its sole
          discretion.  Consultant  will introduce  and/or assist the Client with
          one or more  parties  who might be  interested  in  (whether by way of
          merger,   consolidation,   asset  purchase,   technology  license,  or
          substantially  similar  transaction) either, (a) acquiring some or all
          of Client's  assets or, (b) selling some or all of their own assets to
          Client and/or,  (c) entering into some form of strategic alliance with
          Client.  In consideration of Consultant's  services,  Client agrees to
          pay  Consultant  the Merger Fee ("Merger  Fee") set forth in paragraph
          1.4.a.ii, which is a separate fee from the Engagement Fee.

          i.   PERFORMANCE  BY  CONSULTANT.  Consultant  shall be deemed to have
               earned its entire Merger Fee under  Section  1.4.a.ii  upon,  (i)
               Consultant's  introduction of any potential acquirer or seller of
               assets or merger  candidate  or, (ii) upon  materially  assisting
               Client with merger, acquisition and/or divestiture efforts for an
               introduced   or   non-introduced   merger,   acquisition   and/or
               divestiture  candidate and, (iii) the consummation of the merger,
               acquisition,  and/or  divestiture by Client within 12 months from
               the date of such  introduction  or  effort.  Consultant  shall be
               entitled  to  receive a Merger  Fee (as  described  in  paragraph
               1.4.a.ii., below) for each merger, acquisition and/or divestiture
               by the Client.  Each such obligation of Client to pay such Merger
               Fee shall be deemed a separate agreement hereunder severable from
               each of the other  obligations to pay fees arising  hereunder and
               each  obligation  shall be separately  enforceable as if separate
               written  agreements  existed for each introduction  and/or effort
               made by Consultant. Consultant shall not be deemed to have earned
               any Merger Fee if a merger/acquisition  candidate presents itself
               to Client  independent  from  Consultant  efforts  and the Client

<PAGE>

Consulting Services Agreement                                       Page 3 of 10

               implements  resulting   merger/acquisition  process  without  any
               material assistance or engagement by the Consultant.

          ii.  AMOUNT   AND   PAYMENT   OF    CONSULTANT'S    MERGER   FEE   FOR
               MERGER/ACQUISITION.  For a  merger/acquisition  entered  into  by
               Client  as a result of the  efforts  of,  or AN  INTRODUCTION  BY
               CONSULTANT  during the term of this  Agreement,  Client shall pay
               Consultant,   ten  percent  (10%)  of  the  total  value  of  the
               transaction.

               NOTE:Such  percentage(s)  shall be paid to  Consultant in cash or
               stock at the Client's  discretion.  "Total value" shall  include,
               but is not limited to cash, cash equivalents,  debt or stock, and
               the reasonable  commercial value of any consideration  other than
               cash paid or received  by Client.  All shares  earned  under this
               section that have not been  registered  with the  Securities  and
               Exchange  Commission shall be registered by Client on Form S-8 or
               similar  registration  within  10 days of the  completion  of the
               transaction. All registration filing costs in connection with the
               registration shall be borne by Client.

     b.   PAYMENT.  In addition to the payment of the  Engagement  Fee, which is
          due and payable upon the execution of this  Agreement  pursuant to the
          terms of Section 2 below,  each time a Merger Fee is due as  specified
          in any other  provision of this Agreement,  the Merger Fee amount,  as
          specified  therein,  shall be payable by Client to  Consultant  within
          twenty (20) days of the closing of the transaction. The Merger Fee due
          Consultant  shall  be in  addition  to any fee or funds  which  may be
          payable to any other person or entity as a result of the transaction.

          Consultant  makes no  guarantee  that it will be able to  successfully
          locate a merger or acquisition  target and in turn consummate a merger
          or acquisition  transaction for client,  or to  successfully  complete
          such a transaction  within client's  desired time frame.  Any comments
          made regarding  potential time frames or anything that pertains to the
          outcome of client's  needs are  expressions  of  consultant's  opinion
          only, and for purposes of this agreement are specifically disavowed.

1.5  STANDARD OF PERFORMANCE.  Consultant  shall devote such time and efforts to
     the affairs of the Client as is reasonably necessary to render the services
     contemplated by this Agreement. Any work or task of Consultant provided for
     herein  which  requires  Client to provide  certain  information  to assist
     Consultant in completion of the work shall be excused  (without effect upon
     any  obligation of Client) until such time as Client has fully provided all
     information and cooperation  necessary for Consultant to complete the work.
     The  services of  Consultant  shall not include the  rendering of any legal
     opinions or the performance of any work that is in the ordinary  purview of
     a certified public accountant,  or other licensed professional.  Consultant
     cannot  guarantee  results on behalf of Client,  but shall use commercially
     reasonable  efforts in providing the services  listed above. If an interest
     is communicated to Consultant  regarding satisfying all or part of Client's

<PAGE>

Consulting Services Agreement                                       Page 4 of 10

     business and corporate  strategic  planning needs,  Consultant shall notify
     Client and advise it as to the  source of such  interest  and any terms and
     conditions of such interest.

     to be available to Client by  telephone  during the Term of this  Agreement
     including from time to time to be available  after normal business hours as

2.   COMPENSATION TO CONSULTANT.  As consideration for Consultant  entering into
     this Agreement,  Client agrees to cause 625,000 shares of its common stock,

     H. Walker,  alter egos of Stanton,  Walker & Company in equal quantities of
     312,500 shares each.  The issuance of said shares shall be registered  with

     registration (the "Engagement Fee"). The issuance of said shares shall take
     place within 5 business days of the execution of this agreement.

     Consultant  shall have no  obligation  to perform any duties  provided  for
     herein if payment [cash and/or stock] is not received by consultant  within
     the time periods as stipulated above. In addition, consultant's obligations
     under this  agreement  shall be become null and void if any  payment  owing
     hereunder is not  delivered  within the time periods as  stipulated  above.
     Furthermore,  the  receipt of the  Engagement  Fee due to  consultant  upon
     execution of this agreement is not contingent upon any prior performance of
     any duties  whatsoever  described  within this agreement.  Client expressly
     agrees that the  Engagement  Fee is deemed  earned upon  execution  of this
     agreement and is thereafter  non-refundable  and  non-cancelable  unless it
     shall be determined  through binding  arbitration as set forth in section 6
     hereafter that the Consultant  willfully and intentionally  committed fraud
     or gross negligence in connection with this Agreement.

2.1  EXPENSES.  Client shall  reimburse  Consultant for any expenses that it has
     pre-approved that Consultant  incurred in performing its duties pursuant to
     this  Agreement   (including   printing,   postage,   express  mail,  photo
     reproduction,  travel,  lodging,  and long distance telephone and facsimile
     charges). Such reimbursement shall be payable within thirty (30) days after
     Client's receipt of Consultant' invoice.

3.   INDEMNIFICATION.  The Parties  agree to indemnify  and hold  harmless  each
     other against any and all liability,  loss and costs,  expenses or damages,
     including  but not limited to, any and all expenses  whatsoever  reasonably
     incurred in  investigating,  preparing or defending against any litigation,
     commenced or  threatened,  or any claim  whatsoever or howsoever  caused by
     reason of any injury  (whether  to body,  property,  personal  or  business
     character  or  reputation)  sustained  by any  person  or to any  person or
     property,  arising out of any act, failure to act,  neglect,  any untrue or
     alleged untrue  statement of a material fact or failure to state a material
     fact which thereby makes a statement false or misleading,  or any breach of
     any material representation,  warranty or covenant by the Parties or any of
     their  agents,  employees,  or other  representatives.  Nothing  herein  is
     intended to nor shall it relieve  either party from  liability  for its own
     willful act,  omission or negligence.  All remedies  provided by law, or in
     equity shall be cumulative and not in the alternative.

     this Agreement or at any time thereafter,  disclose,  use or make known for
     its or another's benefit any confidential  information,  knowledge, or data
     of the  Client  or any of its  affiliates  in any way  acquired  or used by
     Consultant during its engagement by the Client.  Confidential  information,
     knowledge  or data of the Client and its  affiliates  shall not include any
     information  that is, or becomes  generally  available  to the public other
     than as a result of a disclosure by Consultant or its representatives.

     name  in  conjunction   with  Client's  press  releases  and  other  Client
     communications   materials  provided  Client  has  received  prior  written
     approval from  Consultant  for each desired use, which approval will not be

     agreement,  shall be  resolved  through  arbitration  rather  than  through
     litigation. With respect to the arbitration of any dispute, the undersigned
     hereby acknowledge and agree that:

          A.   Arbitration is final and binding on the parties;

          B.   The  parties  are  waiving  their  right to seek remedy in court,
               including their right to jury trial;

          C.   Pre-arbitration discovery is generally more limited and different
               from court proceeding;

          D.   The  arbitrator's  award  is  not  required  to  include  factual
               findings or legal reasoning and any party's right of appeal or to
               seek  modification  of  ruling  by the  arbitrators  is  strictly
               limited;

          E.   This  arbitration  provision is specifically  intended to include
               any and all  statutory  claims  which  might be  asserted  by any
               party;

          F.   Each party hereby agrees to submit the dispute for  resolution to
               the American Arbitration Association,  in Phoenix, Arizona within
               fifteen (15) days after receiving a written request to do so from
               the other party;

          G.   If either  party  fails to submit the dispute to  arbitration  on
               request,  then the  requesting  party may commence an arbitration
               proceeding, but is under no obligation to do so;

          H.   Any hearing  scheduled  after an arbitration  is initiated  shall
               take place in Phoenix, Arizona;

          I.   If either party shall institute any court proceeding in an effort
               to  resist   arbitration   and  be   unsuccessful   in  resisting
               arbitration or shall  unsuccessfully  contest the jurisdiction of
               any  arbitration  forum  located in  Phoenix,  Arizona,  over any
               matter  which is the subject of this  agreement,  the  prevailing
               party  shall be  entitled  to recover  from the losing  party its
               legal fees and any out-of-pocket  expenses incurred in connection
               with the  defense  of such  legal  proceeding  or its  efforts to
               enforce its rights to arbitration as provided for herein;

          J.   The parties shall accept the decision of any award as being final

     Consultant  5  day's  written  notice  of  termination.  Additionally,  the

     Agreement.
