of the premises and covenants, agreements, representations, warranties and
payments hereinafter set out, the parties hereto covenant and agree as follows:

1. DEFINITIONS:

         1.01. In this Agreement, the following terms have the following
ascribed meanings:

         (a)      "Dealer" means an authorized seller of Sota Products who has
                  signed an Authorized Dealer Agreement with Sota or a Master
                  Dealer;

<PAGE>

         (b)      "Effective Date" shall mean the date this Agreement is signed;

         (c)      "Inclusion Date" shall mean, respectively, for each
                  Participating Country, that date on which the name of such
                  country is added to the List of Participating Countries
                  appended as Schedule "A" to this Agreement;

         (d)      "Master Dealer" shall mean that Dealer for each Participating
                  Country which El Asia, with the written consent of Sota, has
                  appointed as a Master Dealer and which has concluded a Master
                  Dealer Agreement with Sota;

         (e)      "Net Sales," with respect to sales to Dealers in a
                  Participating Country, shall mean gross sales at established
                  Master Dealer Pricing Levels for such Participating Country
                  less returns, discounts, allowances, bad debts and such other
                  adjustments as may be made in calculating net sales consistent
                  with generally accepted accounting principles;

         (f)      "Participating Country" means a country, other than Canada or
                  the United States of America, which El Asia elects, by the
                  appointment of a Master Dealer, to add to the countries which
                  are subject to this Agreement by adding the name of such
                  country to the List of Participating Countries attached hereto
                  as Schedule "A";

         (g)      "Unit" shall mean a single Sota Device, with the exception of
                  any of Sota's devices manufactured with the intent of
                  marketing in third world countries.

2. SCOPE:

         2.01. Sota has, prior to the date hereof, developed the Sota Products
and established a business enterprise involving the manufacture and marketing of
Sota Products directly, as well as through a network of distributors,
principally in Canada and the United States of America. This existing business
enterprise, except as may be specifically addressed herein, is not the subject
of this Agreement. This Agreement addresses the creation, development and
operation of an international network of Dealers for Sota Products in countries
other than Canada and the United States of America.

         2.02. Except as may be specifically limited by the terms of this
Agreement, Sota is to retain full autonomy and responsibility for the operation
and development of the pre-existing business enterprise.

         2.03 is acknowledged and agreed by both Sota and E. I. Asia that the
international network of Dealers for Sota Products established under this
Agreement shall not be used by either, independently, to promote or advance the
sale of products or services other than the Sota Products.

3. PREMISE:

         3.01. This Agreement is premised upon the personal relationship between
Russell Torlage, President of Sota, and Jason McDiarmid, President of El Asia,
and is founded upon the understanding that Jason McDiarmid will be and remain
the person in charge of the development, operation and management of an
international network of Dealers for Sota Products. Should Jason McDiarmid leave
his employ with El Asia or cease to be the person so in charge, El Asia shall
propose a suitable person to assume responsibility for the development,
operation and management of the international network of Dealers and, with the

<PAGE>

consent of Sota such person shall assume those responsibilities. If, after the
appointment of such person, Sota is dissatisfied with that person's performance
Sota will then give written notice outlining the reasons Sota is dissatisfied.
For a period of ninety (90) days from receiving written notice, El Asia will
have the opportunity to satisfy Sota's concerns. If after ninety (90) days Sota
is still dissatisfied, then Sota will have the right to terminate this Agreement
upon providing thirty (30) days written notice.

4. DEVELOPMENT OF INTERNATIONAL NETWORK OF DEAL:

         4.01. El Asia agrees to endeavour to establish an international network
of Dealers.

         4.02. The procedure to be employed by El Asia in endeavouring to
establish an international network of Dealers shall be:

         (a)      when El Asia has selected a Master Dealer for a country and
                  such Master Dealer has concluded a Master Dealer Agreement
                  with Sota, such country shall be added to Schedule "A" as a
                  Participating Country;

         (b)      the Master Dealer will recruit and engage other Dealers who
                  will each sign an Authorized Dealer Agreement with its Master
                  Dealer;

         (c)      Sota and El Asia will develop a Master Dealer Price List of
                  Sota Products for that Participating Country which shall be
                  provided to the Master Dealer and shall govern the prices at
                  which Sota Products shall be provided by Sota to the Master
                  Dealer. Sota reserves the right to change the Master Dealer
                  Price List if its cost of producing and delivering Sota
                  Products warrant a change. Sota agrees to provide thirty (30)
                  days written notice to El Asia before implementing price
                  changes.

                  Sota and El Asia acknowledge and agree that, with respect to
                  certain third world countries, the Master Dealer prices may
                  have to be established, initially, at levels which are at or
                  near the delivered cost of Sota Products to Sota. In order for
                  this to happen, both Sota and El Asia must jointly agree. In
                  these circumstances, Sota and El Asia agree that it may be
                  necessary to renegotiate, with respect to sales concluded in
                  that Participating Country, the rates at which El Asia's
                  commission is to be calculated and paid.

         (d)      Sota agrees to provide Sota Products to the Master Dealer at
                  the prices set out in the Master Dealer Price List for that
                  Participating Country, and the Master Dealer and Sota shall
                  each maintain records of the amount of Sota Products provided
                  to the Master Dealer and the price paid for all Sota Products
                  on a monthly basis;

         (e)      the Master Dealer and other Dealers shall market and sell Sota
                  Products in their Participating Country only.

5. SOTA'S RIGHTS AND RESPONSIBILITIES:

         5.01. Sota shall be free to continue to market Sota Products globally
in such manner as it sees fit.

         5.02. Should Sota be approached by a person or company wishing to be
appointed as a Master Dealer in a certain country, Sota shall refer such person
or company to El Asia for consideration.

<PAGE>

         5.03. Sota agrees, to the best of its liabilities, to fill orders
received from Master Dealers, and to provide product and technical support,
marketing and promotional materials, and current information respecting Sota
Products. Sota's responsibilities to provide such support, information and
materials shall be limited to providing English language support, information
and materials. El Asia, Master Dealers and Dealers, shall be entitled to use
marketing and promotional materials published and provided by Sota and to
represent themselves as authorized sellers of Sota Products in their
Participating Countries, but, in so doing, shall respect and honour Sota's
intellectual property rights in the Sota Products and copywrited materials,
trademarks and trade names. Nothing herein, however, shall grant El Asia, its
Master Dealers, or Dealers, any right, title, or interest in Sota's trademarks,
trade names or other intellectual property. At no time during or after the term
of this Agreement shall El Asia, Master Dealers or Dealers challenge or assist
others to challenge Sota's trademarks, trade names or other intellectual
property or the registration thereof, or attempt to register any trademarks,
marks or trade names confusingly similar to those of Sota.

         5.04. Should El Asia or any of its Master Dealers or Dealers develop
marketing and promotional materials for use in advertising and promoting the
Sota Products, such marketing and promotional materials must be specifically
approved by Sota before they are published or distributed.

6. COMMISSION:

         6.01. Sota shall first become obligated to pay El Asia commissions on
the sale of Sota Products to Master Dealers in a Participating Country on the
earlier of the date of the first sale of Sota Products to a Master Dealer or
that day which is six months from the Inclusion Date for the Participating
Country (which date, for each Participating Country, shall be called the "Start
Date".)

         6.02. Sota agrees to pay El Asia commission based upon Net Sales in a
Participating Country at the following rates:

         (a)      20% of Net Sales for the first year following the Start Date;

         (b)      15% of Net Sales for the second year following the Start Date;
                  and

         (c)      5% of Net Safes after the end of the second year following the
                  Start Date.

         6.03. Sota shall have the right to set forth cash discounts, to make
such allowances and adjustments, to accept such returns from its customers, and
to write off as bad debts such overdue customer accounts as it deems advisable.
Sota shall be entitled to charge back to El Asia any amounts previously paid or
credited as commission with respect to such cash discounts, allowances,
adjustments, returned items or bad debts. Sota, however, agrees that the amount
of any cash discount provided to a customer and charged back to El Asia's
commission, shall not exceed 5% of the sale price.

         6.03. Sota agrees to pay El Asia commission based upon Net Sales of
7.5% for orders with a minimum of 50 of anyone of Sota's devices in countries
other than Participating Countries of 7.5% on such sales that El Asia initiates.

         6.04. Upon El Asia meeting, and while it continues to meet, all
requirements set out in subparagraph 8.02(d), Sota shall pay El Asia a
commission based upon Net Sales for orders in countries other than Canada, the
United States of America and Participating Countries of 5%.

<PAGE>

7. PAYMENT OF COMMISSION:

         7.01. Sota agrees to pay El Asia commissions earned for each month
within thirty (30) days of the end of such month.

         7.02. Within thirty (30) days of the end of each month, Sota shall
deliver to El Asia its calculation of Net Sales for each Participating Country
for such month showing both the gross revenue received from the sale of Sota
Products and all costs, expenses and adjustments appropriately particularized,
deducted in arriving at Net Sales for such month, together with its cheque,
payable to El Asia, for the commission earned.

         7.03. For a period of sixty (60) days following receipt of such
calculation, El Asia shall have the right to question Sota's calculation by
delivering to Sota written notice that it is questioning the calculation. Upon
receipt of such notice, Sota will provide to El Asia copies of all transaction
records, invoices and other documents supporting its calculation. Should El Asia
not deliver written notice within such sixty (60) day period, Sota's calculation
shall be deemed to be correct, and may not, thereafter, be challenged.

         7.04. Should El Asia notify Sota that it continues to question Sota's
calculations upon a review of the documents from Sota, Sota's calculations of
Net Sales for the Participating Country or Countries questioned, together with
copies of all transaction records, invoices and other supporting documents,
shall be submitted to an independent chartered accountant acceptable to both
Sota and El Asia, whose assessment and ultimate determination of Net Sales for
the said Participating Country or Countries, shall be final and binding.

         7.05. Should the determination of such independent chartered accountant
be within 5% of Sota's calculation of Net Sales, the cost of his review will be
for the account of El Asia; otherwise, it will be paid by Sota.

8. EXCLUSIVE MARKETING RIGHTS:

         8.01. In a Participating Country:

         (a)      In order to earn the exclusive right to market Sota Products
                  in a Participating Country, El Asia, the Master Dealer and
                  Dealers must sell at least 10,000 Units over any six (6) month
                  period within eighteen (18) months of the Start Date for that
                  Participating Country;

         (b)      in order to continue to enjoy the Exclusive right to market
                  Sota Products in a Participating Country, El Asia, the Master
                  Dealer and Dealers, must continue to sell at least 10,000
                  Units over every six (6) month period, after the six (6) month
                  period in which such right was earned;

         (c)      Upon El Asia establishing a new Participating Country, and
                  while El Asia and the Master Dealer meet, and while they
                  continue to meet, all requirements set out in subparagraph
                  8.01(a), Sota shall instruct its own dealers and customers in
                  that Participating Country to place all future orders through
                  the Master Dealer.

         8.02. Globally:

         In order to earn the exclusive right to market Sota Products in all
countries, except Canada and the United States of America. El Asia must:

         (a)      within eighteen (18) months of the Effective Date, earn and
                  maintain the exclusive right to sell Sota Products in at least
                  one Participating Country;

<PAGE>

         (b)      within two (2) years of the Effective Date, earn and maintain
                  the exclusive right to sell Sota Products in at least three
                  (3) Participating Countries;

         (c)      within three (3) years of the Effective Date, earn and

         8.03. Upon El Asia meeting, and while it continues to meet, all
requirements set out in subparagraphs 8.02(a), (b), (c) and (d), El Asia will
have earned the exclusive right to market Sota Products in all countries except
Canada and the United States of America, and shall maintain such exclusive right
as long as it continues to satisfy the requirements of paragraph 8.02(d).

9. SOTA'S SHARE PURCHASE OPTION:

         9.01. As consideration for the rights and opportunities granted to it
by Sota hereunder, E.I. Tech, El Asia's parent corporation hereby grants to
Sota, while this Agreement persists, an option to purchase all or any portion of
200,000 common shares of E.I. Tech from treasury at the price of $0.25 U.S. per
share according to the following timetable:

         (a)      after one (1) year from the Effective Date, Sota may purchase
                  up to 50,000 shares of E.I. Tech;

         (b)      after two (2) years from the Effective Date, Sota may purchase
                  up to an additional 50,000 shares of E.I. Tech; and

         (c)      after three (3) years from the Effective Date, Sota may
                  purchase up to an additional 100,000 shares of E.I. Tech.

         9.02. This option is exercisable by Sota providing notice in writing to
E.I. Tech accompanied by a certified cheque in favour of E.I. Tech for the full
amount of the purchase price, in U.S. dollars, of the shares being then
purchased. When such payment is received, E.I. Tech covenants and agrees to
issue and deliver to Sota share certificates in the name of Sota for the number
of shares so purchased.

         9.04. In the event of any subdivision, consolidation or other change in
the share capital of E.I. Tech while any portion of this option is outstanding,

adjusted in accordance with such subdivision, consolidation or other change in
the share capital of E.I. Tech.

         9.05. E.I. Tech covenants and agrees that it will reserve in its
treasury sufficient shares to permit the issuance and allotment of shares to
Sota in the event this option is exercised.

herein granted shall also immediately terminate.

         10.01. Target Default:

         Should El Asia fail to achieve any of the targets set out in paragraphs
8.02.(a), (b), (c) and (d) within the time limits therein specified, Sota shall
be entitled to terminate this Agreement provided that:

<PAGE>

         (a)      it shall have first given to El Asia a Notice of Default
                  containing particulars of the target which El Asia has failed
                  to meet; and

         (b)      El Asia does not, within thirty (30) days following the
                  delivery of such Notice, provide Sota with verification that
                  it has achieved such target.

         10.02. Other Default:

         The parties hereto agree that if either of them is in default with
respect to any of the other provisions of this Agreement, the Non-Defaulting
Party may give notice to the Defaulting party specifically designating such
default, and within sixty (60) days after its receipt of such notice, the
Defaulting Party shall either:

         (a)      cure such default, or commence proceedings to cure such
                  default and prosecute the same to completion without undue
                  delay; or

         (b)      give the Non-Defaulting Party notice that it denies such
                  default has occurred and is submitting the question to
                  arbitration as herein provided.

         If arbitration is sought, a party shall not be deemed in default until
the matter shall have been determined finally by appropriate arbitration under
the provisions of paragraph 12 hereof.

         If:

         (a)      the default is not so cured or a commencement made on
                  proceedings to cure it, and

         (b)      arbitration is not so sought; or the Defaulting Party is found
                  in arbitration proceedings to be in default, and fails to cure
                  it or commence proceedings to cure it within sixty (60) days
                  after tile rendering of the arbitration award;

the Non-Defaulting Party shall be entitled to seek any remedy it may have on
account of such default.

         10.03. El Asia's Termination:

         El Asia shall be entitled to terminate this Agreement by providing Sota
with thirty (30) days written notice of its intention to do so.

11. CANADIAN AND UNITED STATES MARKETS -El ASIA'S RIGHT OF FIRST REFUSAL:

         11.01. Although this Agreement and the relationship created between
Sota and El Asia concerns the creation, development and operation of an
international network of Dealers for Sota Products in countries other than
Canada and the United :States of America, Sota agrees that should El Asia earn
and maintain the exclusive right to market Sota Products in all countries except
Canada and the United States of America as described in subparagraph 8.03(c)
hereof, Sota will grant to El Asia a Right of First Refusal respecting the
acquisition of the exclusive right to market Sota Products in Canada and the
United States of America.

         11.02. El Asia's Right of First Refusal shall be exercised upon the
following terms:

         (a)      if Sota should receive a bona fide offer from an independent
                  third party (the "Proposed Purchaser") dealing at ,arm's
                  length with Sota to purchase the right to exclusively market
                  Sota Products in Canada and the United States of America
                  (herein called "Marketing Rights") which offer Sota desires to
                  accept, or if Sota intends to sell the Marketing Rights, Sota
                  shall first offer (the "Offer") the Marketing Rights in
                  writing to El Asia upon terms no less favourable than those
                  offered by the Proposed Purchaser or intended to be offered by
                  Sota as the case may be. The Offer shall specify the price and
                  terms and conditions of sale, the name of the Proposed
                  Purchaser, which terms shall, in the case of an intended offer
                  by Sota, mean the person or persons to whom Sota intends to
                  offer the Marketing Rights, and, if the Offer received by Sota
                  from the Proposed Purchaser provides for any consideration
                  payable to Sota otherwise than in cash, the Offer shall
                  include Sota's good faith estimate of the cash equivalent of
                  the non-cash consideration;

<PAGE>

         (b)      if, within a period of thirty (30) days of the receipt of the
                  Offer, El Asia notifies Sota in writing that it will accept
                  same, Sota shall be bound to sell such Marketing Rights to El
                  Asia (subject as hereinafter provided with respect to price)
                  on the terms and conditions of the Offer. If the Offer so
                  accepted by El Asia contains Sota's good faith estimate of the
                  cash equivalent consideration as aforesaid, and if El Asia
                  disagrees with Sota's best estimate, El Asia shall so notify
                  Sota at the time of acceptance, and shall, in such notice,
                  specify what it considers, in good faith, to be the fair cash
                  equivalent and the resulting total purchase price. If El Asia
                  so notifies Sota, the acceptance by El Asia shall be effective
                  and binding upon Sota, and El Asia, and the cash equivalent of
                  any non-cash consideration shall be determined by binding
                  arbitration under the Commercial Arbitration Act of British
                  Columbia pursuant to paragraph 12, and shall be payable to
                  Sota, subject to prepayment as hereinafter provided, within
                  ten (10) days following its determination by arbitration. El
                  Asia shall, in such case, pay to Sota, against receipt of an
                  absolute transfer of the Marketing Rights, the total purchase
                  price which is specified in its notice to Sota, and such
                  amount shall be credited to the amount determined following
                  arbitration of the cash equivalent of any non-cash
                  consideration;

         (c)      if El Asia fails to notify Sota before the expiration of the
                  time limited therefor that it will purchase the Marketing
                  Rights offered, Sota may sell and transfer such Marketing
                  Rights to the Proposed Purchaser at the price and on the terms
                  and conditions specified in the Offer for a period of sixty
                  (60) days, PROVIDED that the terms of this paragraph shall
                  again apply to such Marketing Rights if the sale to the
                  Proposed Purchaser is not completed within the said sixty (60)
                  days.

of such professional mediator, and the conduct of the mediation, shall occur as
soon as practicable.

         12.02. Arbitration:
