                                DAVID P. ANASTASI

                              EMPLOYMENT AGREEMENT

      This EMPLOYMENT AGREEMENT (this "Agreement") is made and entered into as
of October 26, 2000 between AVT Corporation, a Washington corporation ("AVT or
"Employer") and David P. Anastasi ("Executive").

      NOW, THEREFORE, in consideration of the mutual covenants and agreements
set forth herein, Employer and Executive hereby agree as follows:

      1. Employment

      Effective as of November 27, 2000 or such earlier date as Executive may
designate (the "Commencement Date"), Employer hereby employs Executive, and
Executive hereby accepts employment by Employer, as President and Chief
Executive Officer of Employer. Executive will also be entitled to serve as a
member of the Board of Directors of Employer during the term of his employment.
In this position Executive will be reporting directly to the Board of Directors
of AVT and will be responsible for managing all aspects of AVT, including sales,
marketing, product development, customer support, manufacturing, finance and
administration. Executive will have the policy and decision-making authority and
responsibility, and will perform the duties customarily performed by an
executive officer of a corporation that is, in all respects, similar to
Employer. In addition, Executive will assist the Board of Directors in various
business development and long range planning activities and such other duties as
may be reasonably assigned from time to time by Employer's Board of Directors
that relate to the business of Employer, its subsidiaries, or any business
ventures in which Employer or its subsidiaries may participate.

      2. Attention and Effort

      Executive will devote his entire working time, ability, attention and
effort to Employer's business and will skillfully serve its interests during
reasonable business hours during the term of this Agreement; provided, however,
that Executive may devote reasonable periods of time to (a) engaging in personal
investment activities and (b) engaging in charitable or community service
activities, so long as neither of the foregoing additional activities materially
interferes with Executive's duties under this Agreement. Employer further
understands that between the Commencement Date and February 25, 2001, a portion
of Executive's time will be devoted to fulfilling his obligations under a
transition plan with his current employer, including acting as an independent
consultant therefor. Additionally, Executive may serve on the Board of Directors
of his current employer as long as such service is not otherwise prohibited by
Section 8 hereof.

      3. Term

      Unless otherwise terminated pursuant to Section 6, the initial term of
this Agreement shall expire on December 31, 2004. Thereafter, this Agreement
shall automatically renew for additional one-year periods unless terminated
pursuant to Section 6 or unless either party gives the other ninety (90) days
prior written notice of its intent not to renew.

      4. Compensation

      During the term of this Agreement, Employer agrees to pay or cause to be
paid to Executive, and Executive agrees to accept in exchange for the services
rendered hereunder by him, the following compensation:

            4.1 Annual Base Salary

      Executive's compensation shall consist, in part, of an annual base salary
initially established at $300,000, before all customary payroll deductions, for
the term of this Agreement. Such annual base salary shall be paid in
substantially equal installments and at the same intervals as other employees of
Employer are paid. Employer's Board of Directors shall determine any future
increases in the amount of such annual base salary, but may not reduce the
annual base salary.

            4.2 Bonus

      Executive will be entitled to receive, in addition to the annual base
salary described above, with respect to each calendar year during the term of
his employment with Employer commencing with 2001, two types of annual bonuses,
as follows: (A) an annual bonus targeted at an amount aggregating 25% of
Executive's base salary for each year for achievement of specified objectives
for each such year as determined by mutual agreement of Employer and Executive
and set forth in writing within the first 60 days of each calendar year of
employment (the "Objective Bonus"), the aggregate amount of the Objective Bonus
for each year to be allocated pursuant to such agreement among such objectives;
and (B) an annual bonus of up to 25% of Executive's base salary for each year
under AVT's Management Incentive Compensation Plan, and payable in full or in
part as provided in such plan if AVT achieves specified financial performance
levels as set forth in such plan (the "MIP Bonus"). In recognition that
Executive is joining AVT late in the fiscal year, in lieu of this bonus
structure for fiscal 2000, Executive will be paid a $75,000 sign-on bonus on the
Commencement Date. Employer's Board of Directors shall determine the composition
of future bonus programs and any future increases in the amount of such bonus
targets; provided however, that the total annual bonus target Executive will
have an opportunity to receive will be at least $150,000.

                                      -2-

            4.3 Stock Options

            Upon the Commencement Date, Executive will be granted nonqualified
stock options (the "Options") to purchase 750,000 shares of AVT common stock
with an exercise price per share equal to the average of the high and low
trading prices of AVT common stock on the date of grant. Additional options may
be granted annually by the Board of Directors and shall be granted based upon
Employee's performance. The Options will vest over a four year period with the
first 25% (187,500 shares) vested on the first anniversary of the date of grant,
and with 2.0833% of the total shares (15,625 shares) vested each month
thereafter until 100% of such Option shares are fully vested. Notwithstanding
the foregoing, if Executive's employment is terminated prior to the first
anniversary of the Commencement Date for any reason (including due to death or
"total disability" of the Executive) other than by the Board of Directors of AVT
with "Cause," all of the Options that would otherwise have vested on the first
anniversary of the date of grant will be deemed vested on a pro-rata basis over
the first year of employment based on the number of full calendar months
actually served. The Options will be granted pursuant to an Option Agreement
consistent with the terms hereof and will in all respects not specified by the
terms of this Agreement or the Option Agreement be subject to the same terms and
conditions as are set forth in the AVT 1989 Restated Employee Stock Option Plan,
attached hereto as Exhibit A.

      5. Benefits

      During the term of this Agreement, Executive will be entitled to
participate, subject to and in accordance with applicable eligibility
requirements, in fringe benefit programs generally available to employees of
Employer or executives of Employer, as those programs may currently exist or be
modified from time to time. Also, Executive will be entitled to receive an
allowance of $250 per month in reimbursement for club memberships and fees.

      6. Termination

      Employment of Executive pursuant to this Agreement may be terminated as
follows, but in any case the provisions of Section 8 hereof shall survive the
termination of this Agreement and the termination of Executive's employment
hereunder to the extent provided therein:

            6.1 By Employer

      With or without Cause (as hereinafter defined), Employer may terminate
Executive's employment at any time during the term of employment upon giving
Notice of Termination (as hereinafter defined).

                                      -3-
<PAGE>

            6.2 By Executive

      Executive may terminate his employment at any time, with or without Good
Reason (as hereinafter defined), upon giving Notice of Termination.

            6.3 Automatic Termination

      This Agreement and Executive's employment hereunder will terminate
automatically upon Executive's death or total disability. The term "total
disability" as used herein means a physical or mental illness, loss of legal
capacity or any other cause beyond Executive's control that substantially
impairs or prevents Executive from performing his duties hereunder for a period
that can reasonably be expected to be of long or indefinite duration, as
determined in good faith by Employer's Board of Directors, unless Executive is
granted a leave of absence by Employer's Board of Directors. Executive and
Employer hereby acknowledge that Executive's ability to perform the duties
specified in Section 1 hereof is of the essence of this Agreement. Termination
hereunder will be deemed to be effective (a) at the end of the calendar month in
which Executive's death occurs or (b) immediately upon a determination by
Employer's Board of Directors of Executive's total disability, as defined
herein.

            6.4 Notice

      The term "Notice of Termination" means at least 14 days' written notice of
termination of Executive's employment, during which period Executive's
employment and performance of services will continue; provided, however, that
Employer may, upon notice to Executive and without reducing Executive's
compensation during such period, excuse Executive from any or all of his duties
during such period. The effective date of the termination of Executive's
employment hereunder shall be the date of termination set forth in such written
notice.

      7. Termination Payments

      in the event of termination of Executive's employment, all compensation
and benefits set forth in this Agreement will terminate as of the last date of
employment, except as specifically provided in this Section 7:

            7.1 Termination by Employer

      (a) Without Cause.

      If Employer terminates Executive's employment without Cause prior to the
end of the term of this Agreement, Executive will be entitled to receive, in a
lump sum payment due on the date of termination, the sum of (i) an amount equal
to the lesser of (aa) one-year of

                                      -4-
<PAGE>

Executive's then-current annual base salary and (bb) the annual base salary
Executive would have received if his employment hereunder had continued until
the end of the term of this Agreement; (ii) any unpaid annual base salary that
has accrued or is otherwise payable for services already performed as of the
date of termination; and (iii) the amount of any Objective Bonus and/or MIP
Bonus described in Section 4.2 hereof that has been earned by Executive prior to
the date of termination but has not yet been paid to Executive as of such date.

In addition to payments made under 7.1(a)(i), (ii), and (iii), Executive shall
be entitled to receive (1) the Objective Bonus described in Section 4.2 hereof
for the calendar year of termination, payable for all fully achieved objectives
as if Executive were still employed by Employer at the dates of determination
set forth therein, and (2) a portion of the MIP Bonus as described in Section
4.2 calculated as follows: AVT's actual financial performance on the date of
termination shall be annualized and compared against the annual financial
performance target as specified in the MIP Plan. This ratio will be referred to
as the Performance Ratio. If the Performance Ratio is at least 70%, then
Executive shall be entitled to a portion of the MIP bonus, such portion to be
determined by multiplying the MIP Bonus (Section 4.2) by the Performance Ratio
and then by multiplying that number by the number of completed calendar months
of service divided by twelve (12). Executive shall also receive Medical, Dental,
Vision, Life, Short and Long Term Disability Insurance for a period of 12 months
from date of termination for Executive and any dependents covered under
Executive's insurance while Executive was employed.

      (b) With Cause. If Employer terminates Executive's employment with Cause
prior to the end of the term of this Agreement, Executive will not be entitled
to receive any of the foregoing benefits, other than those set forth in clause
(a)(ii) above.

            7.2 Termination by Executive

      (a) With Good Reason. If Executive terminates his employment for Good
Reason prior to the end of the term of this Agreement, Executive will be
entitled to receive all of the payments and other benefits set forth in Section
7.1(a) hereof.

      (b) Without Good Reason. If Executive terminates his employment for any
reason other than Good Reason prior to the end of the term of this Agreement,
Executive will not be entitled to any payments hereunder, other than those set
forth in clause (ii) of Section 7.1(a) hereof.

            7.3 Expiration of Term or Termination Because of Death or Total
                Disability

      In the case of the termination of Executive's employment as a result of
the expiration of the term of this Agreement or because of his death or total
disability as defined above,

                                      -5-
<PAGE>

Executive (or his estate) shall be entitled to receive the payments set forth in
clause (ii) of Section 7.1(a) hereof plus a portion of the Objective Bonus and
MIP Bonus as provided in Section 7.1(a).

            7.4 Change in Control

      A Change in Control, in and of itself, shall not constitute a termination
hereunder nor shall it obligate AVT to make any termination payments hereunder,
unless such Change in Control results in a termination of Executive's employment
that would otherwise entitle him to such payments hereunder. The term "Change in
Control" means (a) any person or group is or becomes the beneficial owner,
directly or indirectly, of securities of AVT representing fifty percent (50%) or
more of the combined voting power of AVT's then outstanding securities; or (b)
the stockholders of AVT approve a merger or consolidation of AVT with any other
corporation; except a merger or consolidation that results in the voting
securities of AVT continuing to represent more than fifty percent (50%) of the
combined voting power of the voting securities of AVT or such surviving entity;
or (c) the stockholders of AVT approve a plan of complete liquidation of AVT or
an agreement for the sale or disposition by AVT of all or substantially all of
its assets.

            7.5 Certain Definitions

      (a) Cause. Wherever reference is made in this Agreement to termination
being with or without Cause, "Cause" means the occurrence of one or more of the
following events without the written consent of Employer:

            (i) Executive's willful material misconduct or dishonesty in the
performance of, or the willful failure to perform, any material duty under this
Agreement;

            (ii) Executive's willful injury of Employer, or Executive's breach
of fiduciary duty to Employer involving personal profit;

            (iii) Conviction of Executive of the violation of a state or federal
criminal law involving the commission of a crime against Employer or any felony;

            (iv) Habitual or repeated misuse by Executive of alcohol or
      controlled substances that materially impairs Executive's ability to
      perform his duties under this Agreement;

            (v) Any material and willful violation by Executive of any
provisions of Sections 8.2 - 8.6 of this Agreement; or

                                      -6-
<PAGE>

      (vi) Any past or present act of Executive involving moral turpitude
adversely affecting the business, goodwill or reputation of Employer, or
materially and adversely affecting Executive's ability to effectively represent
Employer with the public.

      Notwithstanding the foregoing, Executive shall not be deemed to have been
terminated for Cause unless and until Executive has been given written notice
from the Board of Directors of Employer of the alleged ground or grounds for a
proposed termination for Cause, and an opportunity to cure in accordance with
Section 10 hereof, and has failed to effect such cure within the time permitted
therefor.

     (b) Good Reason. Wherever reference is made in this Agreement to

            (i) the assignment to Executive of duties materially inconsistent
with or detrimental to, Executive's position, authority, duties or
responsibilities as contemplated by Section 1 hereof; provided, however, that
the reduction of Executive's position, authority, duties and responsibilities by
Employer following Executive's written notice to Employer that he intends to
resign his position with Employer without Good Reason shall not constitute "Good
Reason" under this Agreement;

            (ii) Employer requiring the Executive to be based at any office or
location other than in the Seattle, WA area, or;

            (iii) Any material violation by Employer of any provision of this
Agreement.

     (c) Willful. For purposes of Sections 7.5(a)(i) and (ii), an act, or
omission to act, on Executive's part shall be considered "willful" only if done,
or omitted to be done, by him not in good faith or without reasonable belief
that his action or omission was in the best interest of Employer; provided, that
any act, or omission to act, on Executive's part in reliance upon an opinion of
counsel to Employer or counsel to Executive shall not be deemed to be willful.

      8. Noncompetition and Nonsolicitation

            8.1 Applicability

      This Section 8 will survive the termination of Executive's employment with
Employer or the expiration of the term of this Agreement to the extent provided

control of, any Competitor unless released from such obligation in writing by
Employer's Board of Directors. A "Competitor" means any entity that competes
with Employer in the production, marketing or distribution of products that
compete with products then produced by Employer. Executive shall be deemed to be
related to or connected with a Competitor if such Competitor is (a) a
partnership in which he is a general or limited partner or employee, (b) a
corporation or association of which he is a shareholder, officer, employee or
director, or (c) a partnership, corporation or association of which he is a
member, consultant or agent; provided, however, that nothing herein will prevent

the outstanding equity securities of a publicly or privately held corporation,
if Executive had no other relationship with such corporation prohibited by this
Section 8.

            8.3 Scope of Nonsolicitation

            8.4 Assignment of Intellectual Property

      All concepts, designs, machines, devices, uses, processes, technology,
trade secrets, works of authorship, customer lists, plans, embodiments,

during the term of his employment hereunder, whether working alone or with
others, shall be Employer's sole and exclusive property, together with any and
all Intellectual Property rights, including, without limitation, patent or
copyright rights, relating thereto, and Executive hereby assigns to Employer all

concepts, designs, machines, devices, uses, processes, technology, trade
secrets, works of authorship, customer lists, plans, embodiments, inventions,
improvements and related work product that (a) relate to Executive's performance
of services under this Agreement, to Employer's field of business or

            8.5 Disclosure and Protection of Inventions

      In the event that Executive develops in the course of his employment with
Employer any material item of Intellectual Property that is the property of
Employer under Section 8.4 hereof, Executive shall disclose to and assist
Employer or its designee in efforts to protect all rights relating to such
Intellectual Property. Such assistance may include, without limitation, the
following: (a) making application in the United States and in foreign counties
for a patent or copyright on any work products specified by Employer; (b)
executing documents of assignment to Employer or its designee of all of
Executive's right, title and interest in and to any work product and related
intellectual property rights; and (c) taking such additional action (including,
without limitation, the execution and delivery of documents) to perfect,
evidence or vest in Employer or its designee all right, title and interest in
and to any Intellectual Property and any rights relating thereto.

            8.6 Nondisclosure; Return of Materials

      During the term of his employment by Employer and following termination of
such employment, Executive will not disclose (except as required by, in
furtherance of or otherwise consistent with his duties to Employer) any
confidential concept, design, process, technology, trade secret, customer list,
plan, embodiment or invention, any other Intellectual Property or any other
confidential information, whether patentable or not, of Employer of which
Executive becomes informed or aware during his employment, whether or not
developed by Executive. In the event of the termination of his employment with
Employer or the expiration of this Agreement, Executive will return all
confidential documents, data and other materials of whatever nature, including,
without limitation, drawings, specifications, research, reports, embodiments,
software and manuals to Employer that pertain to his employment with Employer or
to any Intellectual Property, and shall not retain or cause any third party to
retain photocopies or other reproductions of the foregoing.

            8.7 Equitable Relief

      Executive acknowledges that the provisions of this Section 8 are essential
to Employer, that Employer would not enter into this Agreement if it did not
include this Section 8 and that damages sustained by Employer as a result of a
breach of this Section 8

                                      -9-
<PAGE>

cannot be adequately remedied by traditional legal recourse, and Executive
agrees that Employer, notwithstanding any other provision of this Agreement,
including, without limitation, Section 14 hereof, in addition to any other
remedy it may have under this Agreement or at law, will be entitled to
injunctive and other equitable relief to prevent or curtail any breach of any
provision of Section 8.

            8.8 Effect of Violation

      Executive and Employer acknowledge and agree that additional consideration
has been given for Executive's entering into this Section 8, such additional
consideration including, without limitation, certain provisions for termination
payments pursuant to Section 7. If Executive is terminated with Cause, such
termination shall not relieve Executive of his obligations, as required
hereunder, not to compete.

            8.9 Definition of Employer

      For purposes of Sections 8.2 and 8.3 hereof, "Employer" shall include all
subsidiaries of Employer, and any business ventures in which Employer or its
subsidiaries may participate during the term of Executive's employment

      If any provision of this Agreement is held invalid, illegal or
unenforceable in any jurisdiction, for any reason, including, without

      20. Entire Agreement

      This Agreement on and as of the date hereof constitutes the entire

      21. Legal Expenses

      As represented and warranted in Section 9.2, Executive's participation in
this Agreement and his obligations hereunder shall not violate any other
agreement by which Executive is bound. However, AVT recognizes that Executive
may need assistance in his transition from his current employer. Therefore, in
the event of any claim or threatened claim by Executive's existing employer or
any stockholder or other security holder of Executive's existing employer (a
"Claim") related to Executive's actions within his scope of employment, AVT
agrees to provide a loan of up to $100,000 (the interest bearing rate will be
the minimum annual statutory rate required for Federal income tax purposes) to
be used

                                      -13-
<PAGE>

solely for legal expenses incurred in Executive's defense of any such Claim;
provided that Executive's existing employer does not carry insurance that covers
the costs of such Claim and provided that such Claim does not involve fraudulent
actions on Executive's part. In the case of a Claim involving a violation of law
or fraudulent actions, any loan to assist with legal expenses shall be at the
Board of Directors sole discretion.

                                      -14-

      IN WITNESS WHEREOF, the parties have executed and entered into this

                                 AVT Corporation

                   NONQUALIFIED STOCK OPTION LETTER AGREEMENT

TO: David Anastasi                  Date of Grant:   November 15, 2000

      In accordance with the Employment Agreement dated as of October 26, 2000
(the "Employment Agreement"), the Board of Directors (the "Board") of AVT
Corporation (the "Company") is pleased to grant you a nonqualified stock option
for the purchase of 750,000 shares of the Company's Common Stock at an exercise
price of $5.94 per share. In addition to the terms set forth below, in all
respects not specified by the terms of this agreement or the Employment
Agreement this option shall be subject to the same terms and conditions as are
set forth in the Company's 1989 Restated Stock Option Plan, which is
incorporated herein by reference. In the event of any inconsistency between the
terms of the Employment Agreement and the terms of either this agreement or the
1989 Restated Stock Option Plan where the terms of the Employment Agreement are
more favorable to you, or in the event that any term of this agreement or the
1989 Restated Stock Option Plan purports to deny or limit any right granted to
you by the terms of the Employment Agreement, the terms of the Employment
Agreement shall control and any such other inconsistent, limiting or similar
provision shall have no force or effect.

      Term: The term of the option is ten years from date of grant. unless
sooner terminated.

      Vesting: The option will vest and become exercisable according to the
following schedule:

      Date on and After Which                Vested and Exercisable Portion
   Option is Vested and Exercisable                  of Total Option
   --------------------------------                  ---------------
         November 15, 2001                                  25%
        Each month thereafter                   Add an additional 2.0833%
         November 15, 2004                                 100%

Exercise: During your lifetime only you can exercise the option. The option may
be exercised by the personal representative of your estate, by the beneficiary
you have designated on forms prescribed by and filed with the Company, or the
beneficiary of your estate following your death. Subject to the vesting schedule
set forth above, the
<PAGE>

option may be exercised in whole or in part at any time and from time to time;
provided, however, that no fewer than 100 shares (or the remaining shares then
purchasable under the option, if less than 100 shares) may be purchased upon any
exercise of this option and that only whole shares will be issued pursuant to
the exercise of the option. You may use the Notice of Exercise of Nonqualified
Stock Option in the form attached to this Agreement when you exercise the
option.

      Payment for Shares: The option may be exercised by the delivery of:

      (a) Cash, personal check (unless, at the time of exercise, the Company
determines otherwise), bank certified or cashier's check;

      (b) Unless the Board in its sole discretion determines otherwise, shares
of the capital stock of the Company held by you for a period of at least six
months having a fair market value at the time of exercise, as determined in good
faith by the Board, equal to the exercise price; or

      (c) A properly executed exercise notice together with irrevocable
instructions to a broker to promptly deliver to the Company the amount of sale
or loan proceeds to pay the exercise price.

      Withholding Taxes: As a condition to the exercise of the option, you must
make such arrangements as the Company may require for the satisfaction of any
federal, state or local withholding tax obligations that may arise in connection
with such exercise. The Company has the right to retain without notice
sufficient shares of stock to satisfy the withholding obligation. To the extent
permitted or required by the Company, you may satisfy the withholding obligation
by electing to have the Company or a related corporation withhold from the
shares to be issued upon exercise that number of shares having a fair market
value equal to the amount required to be withheld. If you are subject to Section
16 of the Exchange Act you must comply with certain requirements in order to
make such election.

      Termination: If your relationship with the Company ceases prior to
November 15, 2001 because you are terminated by the Company for any reason
(including due to death or "total disability" as that term is defined in the
Employment Agreement), the shares underlying the option that would otherwise
have vested on November 15, 2001 will be deemed vested on a pro-rata basis over
the first year of employment based on the number of full calendar months
actually served.

      Transferability of Option: This option and the rights and privileges
conferred hereby may not be transferred, assigned, pledged or hypothecated in
any manner (whether by operation of law or otherwise) other than by will or by
the applicable laws

                                      -2-
<PAGE>

of descent and distribution and shall not be subject to execution, attachment or
similar process. This option is personal to you and is exercisable solely by
you. Any attempt to transfer, assign, pledge, hypothecate or otherwise dispose
of this option or of any right or privilege conferred hereby, contrary to the
provisions hereof, or the sale or levy or any attachment or similar process upon
the rights and privileges conferred hereby will be null and void.
Notwithstanding the foregoing, to the extent permitted by applicable law and
regulation, the Company, in its sole discretion, may permit you to (i) during
your lifetime, designate a person who may exercise the option after your death
by giving written notice of such designation to the Company (such designation
may be changed from time to time by you by giving written notice to the Company
revoking any earlier designation and making a new designation) or (ii) transfer
the option and the rights and privileges conferred hercby.

      No Status as Shareholder: Neither you nor any party to whom your rights
and privileges under the option pass will be, or have any of the rights or
privileges of, a shareholder of the Company with respect to any of the shares
issuable upon the exercise of this option unless and until this option has been
exercised.

      Continuation of Relationship: Nothing in this option will confer upon you
any right to continue in the employ or other relationship of the Company, or to
interfere in any way with the right of the Company to terminate your employment
or other relationship with the Company at any time.

      Adjustments Upon Changes in Capitalization:

      The aggregate number and class of shares covered by this option and the
exercise price per share thereof (but not the total price), will all be
proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock of the Company resulting from a split-up or consolidation
of shares or any like capital adjustment, or the payment of any stock dividend.

      (a)   Effect of Liquidation or Reorganization

            (1) Cash. Stock or Other Property for Stock. Except as provided in
subsection (a)(2), upon a merger (other than a merger of the Company in which
the holders of shares of Common Stock immediately prior to the merger have the
same proportionate ownership of shares of Common Stock in the surviving
corporation immediately after the merger), consolidation, acquisition of
property or stock,

                                      -3-
<PAGE>

separation, reorganization (other than a mere reincorporation or the creation of
a holding company) or liquidation of the Company, as a result of which the
shareholders of the Company receive cash, stock or other property in exchange
for or in connection with their shares of Common Stock, this option will
terminate, but you will have the right immediately prior to any such merger,
consolidation, acquisition of property or stock, separation, reorganization or
liquidation to exercise your option, at your election in whole or in part,
whether or not the vesting requirements set forth in this agreement have been
satisfied; provided that such acceleration will not occur if, in the opinion of
the Company's outside accountants, such acceleration would render unavailable
"pooling of interests" accounting treatment for any reorganization, merger or
consolidation of the Company for which pooling of interests accounting treatment
is sought by the Company.

            (2) Conversion of Options on Stock for Stock Exchange. If the
shareholders of the Company receive capital stock of another corporation
("Exchange Stock") in exchange for their shares of Common Stock in any
transaction involving a merger (other than a merger of the Company in which the
holders of Common Stock immediately prior to the merger have the same
proportionate ownership of Common Stock in the surviving corporation immediately
after the merger), consolidation, acquisition of property or stock, separation
or reorganization (other than a mere reincorporation or the creation of a
holding company), this option may be converted into an option to purchase shares
of Exchange Stock unless the Company and the corporation issuing the Exchange
Stock, in their sole discretion, determine that any or all such options granted
hereunder shall not be converted into options to purchase shares of Exchange
Stock but instead shall terminate in accordance with the provisions of
subsection (a)(l) above. The amount and price of converted options will be
determined by adjusting the amount and price of this option in the same
proportion as used for determining the number of shares of Exchange Stock the
holders of the shares of Common Stock receive in such merger, consolidation,
acquisition of property or stock, separation or reorganization. The converted
option will be fully vested whether or not the vesting requirements set forth in
this agreement have been satisfied; provided that such acceleration will not
occur if, in the opinion of the Company's outside accountants, such acceleration
would render unavailable "pooling of interests" accounting treatment

                                      -4-
<PAGE>

for any reorganization, merger or consolidation of the Company for which pooling
of interests accounting treatment is sought by the Company.

      (b) Fractional Shares

      In the event of any adjustment in the number of shares covered by this
option, any fractional shares resulting from such adjustment will be disregarded
and the option will cover only the number of full shares resulting from such
adjustment.

      (c) Determination of Board to Be Final

      All adjustments referred to herein will be made by the Board, and its
determination as to what adjustments will be made, and the extent thereof, will
be final, binding and conclusive.

      Securities Regulation:

      Shares will not be issued with respect to this option unless the exercise
of such option and the issuance and delivery of such shares pursuant thereto
complies with all relevant provisions of law, including, without limitation, any
applicable state securities laws, the Securities Act of 1933, as amended, the
Exchange Act, the rules and regulations promulgated thereunder, and the
requirements of any stock exchange upon which the shares may then be listed.

      As a condition to the exercise of this option, the Company may require you
to represent and warrant at the time of any such exercise that the shares are
being purchased only for investment and without any present intention to sell or
distribute such shares if, in the opinion of counsel for the Company, such a
representation is required by any relevant provision of the aforementioned laws.
At the option of the Company, a stop-transfer order against any shares of stock
may be placed on the official stock books and records of the Company, and a
legend indicating that the stock may not be pledged, sold or otherwise
transferred, unless an opinion of counsel is provided (concurred in by counsel
for the Company) stating that such transfer is not in violation of any
applicable law or regulation, may be stamped on stock certificates in order to
assure exemption from registration. The Company may also require such other
action or agreement by you as may from time to time be necessary to comply with
the federal and state securities laws. THIS PROVISION SHALL NOT OBLIGATE THE
COMPANY TO UNDERTAKE REGISTRATION OF THIS OPTION OR THE SHARES ISSUABLE
HEREUNDER, but if the Company has filed or is filing a Registration Statement on
Form S-8 or any successor form for the registration of securities issued under
stock option or other employee benefit plans, the Company hereby undertakes to
include the shares issuable hereunder in any such registration.

                                      -5-
<PAGE>

      Should any of the Company's capital stock of the same class as the stock
subject to this option be listed on a national securities exchange, all shares
issued hereunder if not previously listed on such exchange will be authorized by
that exchange for listing thereon prior to the issuance thereof.

      Please execute the Acceptance and Acknowledgment set forth below on the
enclosed copy of this Agreement and return it to the undersigned.

                                   Very truly yours,

                                   AVT Corporation
