       NOTICE OF SPECIAL MEETING OF SHAREHOLDERS TO BE HELD JUNE 26, 2000

TO THE SHAREHOLDERS:

     You are cordially invited to attend a Special Meeting of Shareholders of
Arizona Instrument Corporation to be held on Monday, June 26, 2000, at 9:00 a.m.
Mountain Standard Time, at Fiesta Inn, 2100 South Priest Drive, Tempe, Arizona
85282.

     At the special meeting, you will be asked to consider and vote upon the
approval of the Agreement and Plan of Merger, dated as of March 31, 2000, by and
among AZI LLC, George G. Hays, Harold D. Schwartz and Arizona Instrument, as it
may be amended from time to time, providing for the merger (the "Merger") of
Arizona Instrument with and into AZI LLC, with AZI LLC as the "Surviving
Company." Pursuant to the proposed Merger, you will be entitled to receive $5.00
in cash, without interest, for each of your shares of common stock of Arizona
Instrument. AZI LLC is and after the proposed Merger will be controlled
principally by George G. Hays, President and Chairman of the Board of Directors
of Arizona Instrument, Harold D. Schwartz, director of Arizona Instrument, and
G. James Hays, father of George G. Hays. The accompanying proxy statement
explains the proposed Merger and provides specific information concerning the
special meeting. Please read these materials carefully.

     Arizona Instrument's Board of Directors formed a Special Committee of
disinterested directors to mitigate any conflict of interest in evaluating this
Merger proposal and other proposals and indications of interest in Arizona
Instrument, and to negotiate the proposals, including the terms of the Agreement
and Plan of Merger with AZI LLC, and related agreements.

     The Board of Directors of Arizona Instrument, acting on the unanimous
recommendation of the Special Committee, has approved the Agreement and Plan of
Merger and declared the Agreement and Plan of Merger advisable. The Special
Committee and the Board of Directors believe that the terms and provisions of
the Agreement and Plan of Merger and the proposed Merger are fair to, and in the
best interests of, Arizona Instrument's shareholders (other than AZI LLC and its
affiliates). Therefore, THE BOARD OF DIRECTORS, BASED ON THE RECOMMENDATION OF
THE SPECIAL COMMITTEE, RECOMMENDS THAT YOU VOTE IN FAVOR OF THE APPROVAL OF THE
AGREEMENT AND PLAN OF MERGER AND THE TRANSACTIONS CONTEMPLATED THEREBY. In
reaching its decision, the Board of Directors considered, among other things,
the written opinion of Peacock, Hislop, Staley & Given, Inc., the Special
Committee's financial advisor, that, as of March 28, 2000, the $5.00 per share
cash consideration to be received by Arizona Instrument's shareholders in the
proposed Merger was fair to Arizona Instrument's shareholders (other than AZI
LLC and its affiliates) from a financial point of view.

     The proposed Merger is an important decision for Arizona Instrument and its
shareholders. The proposed Merger cannot occur unless, among other things, the
Agreement and Plan of Merger is approved by the affirmative vote of the holders
of a majority of all outstanding shares of common stock of Arizona Instrument.
On behalf of the Board of Directors, I urge you to consider the enclosed
materials carefully and, based on the recommendation of the Special Committee,
recommend you vote "FOR" approval of the Agreement and Plan of Merger and the
transactions contemplated thereby.

                                        Sincerely,


                                        S. Thomas Emerson, Ph.D.
                                        Chairman of the Special Committee
                                        of the Board of Directors

Phoenix, Arizona
______________, 2000

IMPORTANT: It is important that your stockholdings be represented at this
meeting. Whether or not you expect to attend the meeting, please complete, date

the United States. Failure to return an executed Proxy will constitute, in
effect, a vote against approval of the Agreement and Plan of Merger and the
transactions contemplated thereby.

                           PRELIMINARY PROXY STATEMENT

     We are providing this proxy statement and accompanying proxy card to our
shareholders, in connection with the solicitation by our Board of Directors of
proxies to be used at the special meeting of shareholders to be held on June 26,
2000 at 9:00 a.m. Mountain Standard Time at Fiesta Inn, 2100 South Priest Drive,
Tempe, Arizona 85282. This proxy statement and proxy are being mailed to Arizona
Instrument's shareholders beginning about May 30, 2000.

     THIS TRANSACTION HAS NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION NOR HAS THE COMMISSION PASSED UPON THE FAIRNESS OR MERITS OF
SUCH TRANSACTION NOR UPON THE ACCURACY OR ADEQUACY OF THE INFORMATION CONTAINED
IN THIS DOCUMENT. ANY REPRESENTATION TO THE CONTRARY IS UNLAWFUL.

                               SUMMARY TERM SHEET

     The following summarizes the most material terms of our proposed Merger
with AZI LLC. This summary may not contain all the information that you should
consider before voting on the proposed Merger. You should read the entire proxy
statement and all of its annexes before voting on the proposed Merger.

*    The Proposed Transaction. Arizona Instrument will merge with and into AZI
     LLC, with AZI LLC as the Surviving Company. See "THE AGREEMENT AND PLAN OF
     MERGER - The Merger; Merger Consideration."

*    The Acquiring Parties. AZI LLC was formed to engage in the proposed Merger
     by George G. Hays, our Chairman of the Board of Directors and President;
     and Harold D. Schwartz, one of our directors and G. James Hays, father of
     George G. Hays (collectively, the "Founders"). The Founders, except for G.
     James Hays, are also our directors. George G. Hays is a member and the
     Manager of AZI LLC. G. James Hays' affiliate, The Hays Family Revocable
     Lifetime AB Trust dated October 14, 1998, is a member of AZI LLC. Harold D.
     Schwartz's affiliate, Chez & Schwartz Inc. Profit Sharing Plan dated
     December 19, 1973, is a Member of AZI LLC. See "THE PARTIES"; "DIRECTORS
     AND MANAGEMENT - AZI LLC."

*    What You Will Receive in the Merger. You as a shareholder of Arizona
     Instrument will be entitled to receive $5.00 in cash, without interest, for
     each of your shares of Arizona Instrument's common stock. If you are an
     employee, officer or director and own stock options of Arizona Instrument
     at the time of the Special Meeting, you will be entitled to receive, for
     each stock option, cash in an amount equal to the excess, if any, of $5.00
     over the option exercise price. See "THE AGREEMENT AND PLAN OF MERGER - The
     Merger; Merger Consideration."

*    The Special Meeting. A Special Meeting of Shareholders of Arizona
     Instrument will be held at 9:00 a.m., Mountain Standard Time, on June 26,
     2000, at Fiesta Inn, 2100 South Priest Drive, Tempe, Arizona 85282. At the
     special meeting, you will be asked to consider and vote on a proposal to
     approve the Agreement and Plan of Merger described in this proxy statement.
     See "INFORMATION CONCERNING THE SPECIAL MEETING - Time, Place and Date";
     "INFORMATION CONCERNING THE SPECIAL MEETING - Purpose of the Special
     Meeting."

*    Who Can Vote. Only holders of shares of Arizona Instrument common stock who
     are holders at the close of business on the record date, May 15, 2000, will
     be entitled to notice of, and to vote at, the special meeting. On the
     record date, there were 1,371,399 shares of common stock outstanding and
     entitled to vote, held by approximately 2,839 shareholders of record. Each
     share of common stock is entitled to one vote per share. As of May 15 ,
<PAGE>
     2000, 1,371,399 votes were eligible to be cast at the special meeting. See
     "INFORMATION CONCERNING THE SPECIAL MEETING - Record Date; Voting at the
     Meeting; Quorum."

*    Required Vote. Delaware law requires that the holders of a majority of the
     voting power of all outstanding shares of Arizona Instrument common stock
     vote to approve the Agreement and Plan of Merger. The Founders currently
     own 49,188 shares of Arizona Instrument common stock in the aggregate,
     representing approximately 4% of the outstanding shares of common stock as
     of the record date. See "INFORMATION CONCERNING THE SPECIAL MEETING -
     Required Vote."

*    The Special Committee. The Founders are two of the four members of our
     Board of Directors and they have a conflict of interest in recommending
     approval of the Agreement and Plan of Merger because they have a beneficial
     interest in AZI LLC. If the Merger occurs, these two individuals will
     beneficially own a majority of the membership units of AZI LLC, the
     surviving company following the Merger and as a result will receive the
     majority of the benefit of future earnings, growth and increased value of
     the business of Arizona Instrument, while you will no longer receive any
     such benefit. To counteract this conflict of interest, the Board of
     Directors formed a Special Committee consisting of two disinterested
     directors to evaluate and negotiate the terms of the Agreement and Plan of
     Merger with AZI LLC, the company formed by the Founders. The Special
     Committee retained financial advisors to evaluate the fairness of the
     proposed transaction to shareholders from a financial point of view. The
     Special Committee received an opinion from its financial advisor, on which
     the Special Committee and the Board of Directors relied, that as of its
     date (assuming you are a person other than AZI LLC or one of its
     affiliates) the $5.00 per share you will receive in the proposed Merger is
     fair to you from a financial point of view. See "SPECIAL FACTORS - Special
     Committee"; "SPECIAL FACTORS - Board of Directors of Arizona Instrument."

In the opinion of the Board of Directors, based upon the unanimous
recommendation of the Special Committee, the terms and provisions of the
Agreement and Plan of Merger and the proposed Merger are fair to and in the best
interests of Arizona Instrument's shareholders (other than AZI LLC and its
affiliates), and the Board of Directors has accordingly approved the Agreement
and Plan of Merger and declared it advisable. See "SPECIAL FACTORS -
Recommendation of the Special Committee and Board of Directors; Fairness of the
Merger."

*    Conditions to the Merger. A number of conditions must be satisfied before
     Arizona Instrument or AZI LLC is obligated to complete the Merger,
     including, among others, the following:

     *    the Merger must be approved by a majority of the voting power held by
          the shareholders of Arizona Instrument; and

     *    there must be no legal or judicial restraints or prohibitions
          preventing completion of the Merger.

Additional conditions involving the funding of the financing for the Merger and
compliance with representations, warranties and covenants must be satisfied by
Arizona Instrument or waived by AZI LLC before AZI LLC is obligated to complete
the Merger. Additional conditions involving the compliance with representations,
warranties and covenants must be satisfied by AZI LLC or waived by Arizona
Instrument before Arizona Instrument is obligated to complete the Merger. See
"THE AGREEMENT AND PLAN OF MERGER - Conditions."

*    Termination of the Agreement and Plan of Merger. Arizona Instrument and AZI
     LLC may agree at any time (including any time after the special meeting) to
     terminate the Agreement and Plan of Merger. In addition, either Arizona
     Instrument or AZI LLC may terminate the Agreement and Plan of Merger
     without the agreement of the other party under certain circumstances. See
     "THE AGREEMENT AND PLAN OF MERGER - Termination."

*    Acquisition Proposals. In the Agreement and Plan of Merger, Arizona
     Instrument agrees not to solicit or encourage any acquisition proposal for
     Arizona Instrument's assets or common stock which, upon consummation, would
     materially interfere with the Merger. In addition, Arizona Instrument
     agrees not to engage in any discussions or provide access to information
     about Arizona Instrument with respect to any such acquisition proposal
     except under certain circumstances. Under the terms of the Agreement and
     Plan of Merger, neither the Board of Directors nor the Special Committee is
     permitted to engage in negotiations with respect to an acquisition
     proposal, withdraw or modify its recommendation of the Merger and the
     Agreement and Plan of Merger, or approve, declare advisable or recommend an
<PAGE>
     acquisition proposal other than the Merger, except under certain
     circumstances. See "THE AGREEMENT AND PLAN OF MERGER - Acquisition
     Proposals."

*    Fees and Expenses. Under certain circumstances, Arizona Instrument will pay
     AZI LLC a termination or "break up" fee equal to the out of pocket expenses
     of AZI LLC incurred after January 31, 2000 in connection with the proposed
     Merger, but not more than $100,000. See "THE AGREEMENT AND PLAN OF MERGER -
     Fees and Expenses."

*    Federal Income Tax Consequences. The cash you receive for your shares
     generally will be taxable for U.S. federal income tax purposes. See
     "MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER."

*    Dissenters' Rights. Any shareholder who does not wish to accept $5.00 per
     share cash consideration in the Merger has the right under Delaware law to
     have his, her or its shares appraised by the Delaware Chancery Court. This
     "right of appraisal" is subject to a number of restrictions and technical
     requirements. Generally, in order to exercise appraisal rights, among other
     things:

     *    you must NOT vote in favor of the Agreement and Plan of Merger; and

     *    you must make a written demand for appraisal in compliance with
          Delaware law BEFORE the vote on the Agreement and Plan of Merger.

Merely voting against the Agreement and Plan of Merger will not preserve your
right of appraisal under Delaware law. Annex C to this proxy statement contains
the Delaware statute relating to your right of appraisal. Failure to follow all
of the steps required by this statute will result in the loss of your right of
appraisal. See "DISSENTERS' RIGHTS OF APPRAISAL"; ANNEX C.

           SELECTED CONSOLIDATED FINANCIAL DATA OF ARIZONA INSTRUMENT

     The following table sets forth selected consolidated financial data for
Arizona Instrument and its subsidiaries as of and for each of the two fiscal
years for the periods ended December 31, 1998 and 1999. No separate financial
information is provided for AZI LLC since it is a special purpose entity formed
in connection with the proposed Merger and has no independent operations. No pro
forma data giving effect to the proposed Merger is provided because Arizona
Instrument does not believe such information is material to shareholders in
evaluating the proposed Merger and Agreement and Plan of Merger since (1) the
proposed merger consideration is all cash and (2) if the proposed Merger is
completed, the common stock of Arizona Instrument would cease to be publicly
traded.

     The financial information for Arizona Instrument as of and for each of the
two fiscal years for the periods ended December 31, 1998 and 1999, has been
derived from the consolidated financial statements of Arizona Instrument which
have been audited by McGladrey & Pullen L.L.P. and its predecessor in interest.
All such adjustments, except for acquisition transaction costs, are of a normal
recurring nature. The following financial information should be read in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operation" and the Consolidated Financial Statements of Arizona
Instrument and the notes thereto included in Arizona Instrument's Annual Report
on Form 10-KSB for the fiscal year ended December 31, 1999, which is attached to
this proxy statement.

AZI LLC

     AZI LLC ("AZI LLC") was organized in Arizona on March 7, 2000, by George G.
Hays in connection with the proposed Merger. AZI LLC has not been engaged in any
business activities other than those in connection with the Merger. The
principal office and business address of AZI LLC is c/o Mr. George G. Hays,
Manager, 1912 West 4th Street, Tempe, Arizona 85281. The telephone number of AZI
LLC is (602) 470-1414.

                                 SPECIAL FACTORS

Background of the Merger

     On September 25, 1998, Arizona Instrument held an informal meeting of its
Board of Directors to discuss strategy. The Board of Directors discussed several
strategic alternatives for increasing shareholder value, including new product
development, strategic alliances, acquisitions and divestitures. George Hays,
President of Arizona Instrument, was directed to further study the matter. In
addition, the Board of Directors discussed the ongoing decline in the Arizona
Instrument stock price and the delisting letter which Arizona Instrument
received from Nasdaq due to an insufficient bid price for the Arizona Instrument
common stock. Mr. Hays was directed to develop a strategy to prevent delisting.

     In order to prevent delisting, Arizona Instrument effected a 1 for 5
reverse split of outstanding common stock. The stock split was approved by
Arizona Instrument's shareholders at a special meeting held February 5, 1999,
and became effective on February 16, 1999.

     On February 16, 1999, Arizona Instrument announced that it had received a
letter from BP Oil Company demanding the return of approximately $1.9 million
previously paid by BP Oil Company to Arizona Instrument in prior years for the
purchase of Encompass tank gauge systems, the removal of Encompass systems from
BP Oil Company sites, and for the cancellation of any outstanding invoices from
Arizona Instrument. This letter was followed by a lawsuit which BP Oil Company
filed in March 1999, seeking approximately $2.0 million in actual damages plus
an additional several million dollars in incidental and consequential damages.

     On February 26, 1999, the Board of Directors of Arizona Instrument met and
discussed the prospective future performance of the Encompass product line in
light of the BP Oil Company dispute. After considerable deliberation, the Board
of Directors concluded that the actions of BP Oil Company had severely damaged
Arizona Instrument's ability to conduct the Encompass business. The Board of
Directors recommended that Arizona Instrument investigate potential acquirers
for the Encompass and Soil Sentry product lines.

     On March 26, 1999, the Board of Directors of Arizona Instrument met and Mr.
Hays reported on the investigation of potential acquirers of the Encompass
product line. Due to the damage suffered by the BP Oil Company dispute, few
interested purchasers were identified. Conversations with credible investment
bankers confirmed the difficulty in marketing the product line due to the damage
caused by the BP Oil Company dispute. Mr. Hays presented two prospective
purchasers for the Encompass product line, USTMAN and NESCO. The Board of
Directors authorized Mr. Hays to negotiate the sale of the Encompass and Soil
Sentry assets to NESCO for approximately $1.0 million and a 5% royalty on sales
for two years. The Board of Directors recommended that the transaction be closed
as soon as possible with a target date of April 30. The transaction was closed
on substantially the authorized terms on April 30, 1999.
<PAGE>
     On May 7, 1999, the Board of Directors met and once more held a general
discussion regarding the future of Arizona Instrument, and potential strategic
alternatives available to Arizona Instrument to increase shareholder value. The
Board of Directors discussed whether Arizona Instrument should remain in its
current form, due to its small size, lack of growth, and the illiquidity of its
shares, or whether Arizona Instrument should investigate strategic alternatives
to increase shareholder value such as a merger, acquisition, sale of
substantially all of Arizona Instrument's assets, leveraged buyout or other
business combination. The Board of Directors determined that it would further
consider the intrinsic value of Arizona Instrument. During this meeting, Mr.
Hays expressed his potential interest in acquiring Arizona Instrument, if
financing could be arranged to provide shareholders with a fair price.

     During June and July 1999, Mr. Hays held preliminary discussion with
several prospective financing sources to determine the feasibility of financing
the acquisition of Arizona Instrument. During this period, Mr. Hays held several
discussions with Harold D. Schwartz, a member of Arizona Instrument's Board of
Directors, concerning Mr. Schwartz's interest in pursuing a buyout of Arizona
Instrument with Mr. Hays. In July, 1999, Arizona Instrument settled the BP Oil
Company lawsuit.

     On July 30, 1999, Arizona Instrument held a meeting of its Board of
Directors to further examine the intrinsic value of Arizona Instrument.

     Subsequent to the review of the valuation of Arizona Instrument, the Board
of Directors then entered into a discussion of strategic alternatives for
Arizona Instrument to increase shareholder value. The Board of Directors
discussed the possibility of alternatives such as a merger, acquisition, sale of
substantially all of Arizona Instrument's assets, leveraged buyout or other
business combination. During this discussion, Mr. Hays indicated that he and Mr.
Schwartz were interested in acquiring Arizona Instrument and that the financing
for such an acquisition was likely to be obtained. After discussion, the Board
of Directors resolved to consider strategic alternatives for Arizona Instrument
to increase shareholder value, such as a merger, acquisition, sale of
substantially all of Arizona Instrument's assets, leveraged buyout or other
business combination, either with or without the involvement of members of
management.

     The Board of Directors then evaluated the advisability of issuing a press
release with respect to the decision by the Board of Directors to consider
strategic alternatives. The Board of Directors resolved to issue a press release
concerning strategic alternatives.

     Based on advice of counsel, the Board of Directors then formed a Special
Committee composed of the disinterested directors, S. Thomas Emerson, Ph.D. and
Steven G. Zylstra to consider and act on all proposals regarding business
combination transactions involving Arizona Instrument to consider and act upon
any merger, acquisition, sale of assets, leveraged buyout or other business
combination involving Arizona Instrument. Subsequent to establishing a Special
Committee, the Board of Directors meeting was adjourned.

     On July 30, 1999, the Special Committee held its initial meeting, at which
Dr. Emerson was appointed Chairman, and Quarles & Brady LLP, counsel for Arizona
Instrument, was retained as counsel to the Special Committee. The Committee was
informed of its responsibilities by Mr. Moya of Quarles & Brady LLP. The Special
Committee determined to secure a fairness opinion for any potential transaction.
In addition, the Special Committee members agreed that they would ask Mr. Hays
for a report on the persons and entities that had been in contact with Arizona
Instrument and had expressed an interest in acquiring some or all of Arizona
Instrument or its assets.

     On August 2, 1999, Arizona Instrument issued a press release indicating
that its Board of Directors had agreed to consider strategic alternatives for
Arizona Instrument in a move to increase shareholder value. The release
indicated that these alternatives could include a transaction such as a merger,
acquisition, sale of assets, or leveraged buyout, either with or without the
involvement of members of management. That same day, Mr. Hays sent the Special
Committee a report on the persons and entities that had been in contact with
Arizona Instrument during the recent past and had expressed an interest in
acquiring some or all of Arizona Instrument or its assets.

     On August 16, 1999, the Special Committee held a meeting with its counsel.
At that meeting, Mr. Hays was asked to present a report on the persons and
entities that had been in contact with Arizona Instrument and had expressed an
interest in acquiring some or all of Arizona Instrument or its assets. The
Committee determined that it would respond to previous expressions of interest
<PAGE>
in Arizona Instrument, and, in addition, engage in a solicitation of potentially
interested parties. Mr. Zylstra agreed to create a list of potentially
interested parties based upon the recent market studies of Arizona Instrument's
markets prepared by an outside market research firm. Mr. Zylstra instructed Mr.
Hays to send information packages with respect to Arizona Instrument under Dr.
Emerson's signature to potentially interested parties on the list, together with
a cover letter inviting their response.

     The Committee also discussed the advisability of hiring a financial advisor
and obtaining a fairness opinion. After discussion, the Committee agreed that
Dr. Emerson would contact two investment banks, Peacock, Hislop, Staley & Given,
Inc. and Carmichael & Co. LLC, to inquire as to the cost of a fairness opinion
in connection with a proposed business combination transaction involving Arizona
Instrument, and would report back to the Committee at the next meeting.

     Dr. Emerson and Mr. Zylstra then formalized the mechanics of (a) responding
to persons and entities that would contact Arizona Instrument to express an
interest in acquiring some or all of Arizona Instrument or its assets, and (b)
soliciting such expressions of interest. The Committee then directed Quarles &
Brady LLP to prepare forms of a confidentiality agreement and cover letters to
be used in the strategic alternatives process.

     On August 25, 1999, Mr. Zylstra delivered a list of potentially interested
parties to Mr. Hays, and instructed Mr. Hays to deliver solicitation packages to
them. Between August 30, 1999 and September 3, 1999, 52 solicitation packages
were sent under Dr. Emerson's signature to potentially interested parties.

     During September and October 1999, Dr. Emerson discussed the level of
interest in Arizona Instrument with several potentially interested parties,
including Herbert W. Morgan III. On September 12, 1999, Arizona Instrument
received a letter from Mr. Morgan requesting a seat on Arizona Instrument's
Board of Directors. In addition, on September 12, 1999, the Special Committee
received a letter from Mr. Morgan proposing a significant restructuring of
Arizona Instrument. On September 14, the Board of Directors of Arizona
Instrument discussed Mr. Morgan's request for a seat on the Board of Directors.
On September 15, 1999, Arizona Instrument sent Mr. Morgan a letter declining his
request for a seat on the Board of Directors and requesting specific information
regarding his restructuring proposal.

     On September 15, 1999, the Special Committee met and reviewed the responses
to the solicitation mailing earlier in the month. At this meeting, the Special
Committee reviewed the expressions of interest from eighteen parties. Of the
expressions of interest, the Special Committee determined to pursue discussions
concerning a strategic transaction with four parties, to request additional
information regarding their expressed interest from seven parties and to decline
the expressed interest of seven parties. The Special Committee then directed
Quarles & Brady LLP to draft the form of follow up letters for these parties.

     On September 24, 1999, Dr. Emerson and Mr. Hays meet with Mr. Morgan and
his associate, Donald J. Moore, to discuss Mr. Morgan's ideas for Arizona
Instrument. Dr. Emerson requested that Mr. Morgan deliver a specific proposal
for a strategic transaction to him for consideration by the Special Committee.

     On October 1, 1999, Arizona Instrument sent follow up letters to the
interested parties selected by the Special Committee.

     On October 2, 1999, Mr. Morgan sent a letter to Arizona Instrument
requesting three seats on Arizona Instrument's Board of Directors.

     On October 7, 1999, Mr. Hays sent a letter to the Special Committee
withdrawing his interest in acquiring Arizona Instrument. In the letter Mr. Hays
stated that with the increase in stock price and interest expressed by other
parties, that Arizona Instrument's initiative to increase shareholder value had
been an unqualified success.

     On October 8, 1999, the Board of Directors met telephonically, accepted Mr.
Hays' withdrawal of interest in a strategic transaction with Arizona Instrument
and disbanded the Special Committee.

     On October 13, 1999, Arizona Instrument sent Mr. Morgan a letter declining
his request for three seats on its Board of Directors and reminding Mr. Morgan
that Arizona Instrument had not received any details concerning Mr. Morgan's
proposed strategic transaction.
<PAGE>
     On October 18, 1999, Mr. Morgan sent a letter to all shareholders of
Arizona Instrument requesting their support in calling a special meeting of
shareholders to elect a new Board of Directors. Subsequent to Mr. Morgan's
letter to shareholders seeking support for a shareholders' meeting, parties
interested in a strategic transaction deferred their expressions of interest.

     On October 29, 1999, Mr. Morgan withdrew his interest in calling a
shareholders meeting.

     During November and December 1999, Arizona Instrument reestablished
communication with potentially interested parties. Over the course of these
discussions, Arizona Instrument was able to generate one proposal from an
outside party to enter into a transaction which would increase Arizona
Instrument shareholder value.

     On December 27, 1999, the Board of Directors met and concluded the
Strategic Alternatives process. Mr. Hays was directed to begin discussions with
the potentially interested party who had submitted a proposal to acquire Arizona
Instrument. From December 28, 1999 through January 20, 2000, Arizona Instrument
attempted, without success, to begin discussions with the potentially interested
party.

     On January 18, the Board of Directors met and indicated to Mr. Hays that it
would be receptive to a proposal from him to enter into a strategic transaction
with Arizona Instrument. At that time, Mr. Hays discussed his interest in
acquiring Arizona Instrument with Harold D. Schwartz, a director of Arizona
Instrument, and G. James Hays, the father of George G. Hays.

     On January 26, 2000, Arizona Instrument received a written indication of
interest from a third party in acquiring all outstanding common stock of Arizona
Instrument at a purchase price of $5.00 per share. On January 31, 2000, a group
led by Mr. Hays presented a written proposal to Arizona Instrument to acquire
all outstanding common stock at a price of $5.00 per share.

     On January 31, 2000, the Board of Directors met to consider these two
offers to acquire all of the outstanding stock of Arizona Instrument. Since one
of the offers was from a group led by Mr. Hays, the Special Committee was
re-established to consider the proposals. The Board of Directors meeting was
adjourned and a meeting of the Special Committee was convened and considered two
proposals to acquire Arizona Instrument at $5.00 per share. The counsel to the
Special Committee began by explaining the standard of care applicable to the
Special Committee in evaluating the offers to acquire all outstanding stock of
Arizona Instrument. The Committee members considered the merits of the two
offers. Upon the conclusion of the deliberations, the Special Committee
unanimously agreed to recommend acceptance of the offer by Mr. Hays.

     The meeting of the Board of Directors was then reconvened. The Special
Committee reported to the entire Board of Directors its recommendation that the
Board of Directors approve the proposal from Mr. Hays. The Special Committee
described its analysis and evaluation of the alternative proposals and the
reasons for its recommendation. The Board of Directors unanimously accepted and
adopted the Special Committee's recommendation that the Board of Directors
approve the proposal presented by Messrs. Hays and Schwartz.

     On February 1, 2000, Arizona Instrument issued a press release indicating
that Arizona Instrument had entered into a letter of intent pursuant to which an
entity to be formed by Mr. Hays, Harold D. Schwartz, and G. James Hays would
acquire all of Arizona Instrument's outstanding shares not owned by them at a
price of $5.00 per share in cash.

     Subsequent to announcement of the letter of intent, the Special Committee
received indications of interest from two parties (including the party who made
the January 26 proposal) in structuring transactions that could potentially
result in more value for shareholders than the Hays offer. On February 9, 2000,
the Special Committee met to consider a proposal from one of these parties. In
the meeting, the Special Committee determined that the proposal was
insufficiently precise to allow the Committee to reach a judgement as to whether
or not the party could complete the transaction as proposed. In particular, the
Committee considered what additional information might be necessary to permit a
proper evaluation of the proposal. As a result, a request for additional
information was sent by the Committee.
<PAGE>
     On February 15, 2000, Dr. Emerson received a communication from another
potentially interested party regarding the status of the strategic alternatives
process. In response, Dr. Emerson requested a specific proposal from this party.
Subsequent to this request, several communications occurred between Dr. Emerson
and the potentially interested party. No specific proposal was received by the
Special Committee.

     Pursuant to a letter agreement dated February 1, 2000, the Special
Committee retained the investment banking firm of Peacock, Hislop, Staley &
Given, Inc. to render an opinion as to the fairness of the Hays proposal from a
financial point of view.

     On March 28, 2000, the Special Committee met to review the specific terms
of the acquisition agreement and to receive the report from Peacock, Hislop,
Staley & Given, Inc., regarding the fairness of the proposed Hays transaction.

     The Special Committee accepted the fairness opinion, but deferred on any
approval of the Hays proposal until it determined whether the party that had
made the January 26, 2000, proposal had any interest in further discussions with
Arizona Instrument. On March 30, 2000, Dr. Emerson was informed that such third
party had no continuing interest in making a proposal to Arizona Instrument.

     On March 31, 2000, the Special Committee met to discuss the outcome of Dr.
Emerson's contact with the party who made the January 26, 2000, proposal and to
consider the approval of the Hays proposal and the form of Agreement and Plan of
Merger which had been previously presented to the Special Committee. The Special
Committee approved the Hays proposal, the form of the Agreement and Plan of
Merger and the transactions contemplated thereby, including the merger, and
declared that such transactions were advisable, fair to and in the best
interests of Arizona Instrument and its shareholders, and recommended that the
shareholders approve such transactions. The Special Committee unanimously
recommended such transactions to the Board of Directors.

     On the same day, the Board of Directors met to receive and consider the
recommendations of the Special Committee. The Board of Directors approved the
Merger Agreement and all the transactions contemplated thereby, including the
merger, declared that such transactions were advisable, fair to, and in the best
interests of Arizona Instrument and its shareholders, and recommended that
shareholders of Arizona Instrument approve the Merger Agreement and Merger.

     Recommendation of the Special Committee and Board of Directors; Fairness of
the Merger

     On March 31, 2000, the Special Committee approved the Agreement and Plan of
Merger, determined that the merger of Arizona Instrument with and into AZI LLC,
with AZI LLC as the Surviving Company was advisable and that the terms and
provisions of the Agreement and Plan of Merger are fair to, and in the best
interests of, Arizona Instrument's shareholders (other than AZI LLC and its
affiliates). At that time, the Special Committee unanimously recommended to the
entire Board of Directors that it, among other things, approve and declare
advisable the Agreement and Plan of Merger.

     At a meeting of the Board of Directors held immediately following the
Special Committee's meeting on March 31, 2000, the Board of Directors considered
the recommendations of the Special Committee. The Board of Directors concluded
that the terms and provisions of the Agreement and Plan of Merger are advisable
and fair to, and in the best interests of, Arizona Instrument's shareholders
(other than AZI LLC and its affiliates), approved the Agreement and Plan of
Merger, declared the Agreement and Plan of Merger advisable, and recommended
that the shareholders approve the Agreement and Plan of Merger and the
transactions contemplated thereby. Mr. Schwartz did not participate in this
meeting. Mr. Schwartz, however, did not dissent from the actions of the Board of
Directors and, as discussed below under "AZI LLC's Purpose and Reason for the
Merger," Mr. Schwartz believes that the Merger is fair to the shareholders of
Arizona Instrument.

Special Committee

     In approving and recommending that the Board of Directors approve the
Agreement and Plan of Merger and in declaring and recommending that the Board of
Directors declare the Agreement and Plan of Merger advisable and the
transactions contemplated thereby to be fair to and in the best interests of
Arizona Instrument's shareholders, the Special Committee considered the
<PAGE>
following factors, each of which, in the opinion of the Special Committee,
supported its determination.

*    LIMITATIONS AS A PUBLIC COMPANY. The Special Committee considered the fact
     that Arizona Instrument's limited trading volume, institutional sponsorship
     and public float, small market capitalization, and diminishing research
     attention from market analysts, had adversely affected the trading markets
     for, and the value of, Arizona Instrument's common stock. The Special
     Committee also considered its discussions with Peacock Hislop with respect
     to these market and trading considerations. The Special Committee concluded
     that in the circumstances then existing, the $5.00 per share cash
     consideration to be received by shareholders other than AZI LLC and its
     affiliates pursuant to the Agreement and Plan of Merger was preferable to
     continuing to hold shares in the public company. Accordingly, the Special
     Committee concluded that shareholder value was not likely to be maximized
     if Arizona Instrument were to remain a public company.

*    FINANCIAL PERFORMANCE AND FUTURE PROSPECTS. The Special Committee
     considered the inconsistent results of operations over a period of several
     years and the recent disposition of a product line that previously had been
     expected to be a significant factor in the company's growth. The Special
     Committee also considered the impact that these factors had and could have
     on the value of Arizona Instrument's shares in the future and Arizona
     Instrument's overall value as a going concern.

*    OPINION OF PEACOCK HISLOP. The Special Committee considered the financial
     presentation of Peacock Hislop's oral opinion delivered at the March 28,
     2000 meeting of the Special Committee (which was subsequently confirmed in
     writing) to the effect that, as of the date of its opinion and based upon
     and subject to the matters stated in its opinion, the $5.00 per share
     Merger Consideration to be received by Arizona Instrument's shareholders in
     the Merger was fair to Arizona Instrument's shareholders (other than AZI
     LLC and its affiliates) from a financial point of view. THE FULL TEXT OF
     PEACOCK HISLOP'S WRITTEN OPINION, WHICH SETS FORTH THE ASSUMPTIONS MADE,
     MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEW UNDERTAKEN BY PEACOCK
     HISLOP, IS ATTACHED AS ANNEX B TO THIS PROXY STATEMENT AND IS INCORPORATED
     HEREIN BY REFERENCE. SHAREHOLDERS ARE URGED TO, AND SHOULD, READ THE
     OPINION OF PEACOCK HISLOP. The presentation of and the factors considered
     by Peacock Hislop in its fairness opinion, as discussed under "SPECIAL
     FACTORS--Opinion of Financial Advisor to the Special Committee," supported
     the Special Committee's determination.

*    MARKET PRICE AND PREMIUM. The Special Committee considered that (1) the
     $5.00 per share to be received by Arizona Instrument's shareholders in the
     Merger exceeded by 41% the volume-weighted average stock price for the 12
     months prior to the public announcement of Mr. Hays' $5.00 per share
     indication of interest letter, and (2) the Merger Consideration represented
     a 21% premium to the stock price the day prior to the public announcement
     of Arizona Instrument's pursuit of strategic alternatives, a 94% premium to
     Arizona Instrument's estimated volume-weighted average stock price for the
     six months prior to the public announcement of Arizona Instrument's
     pursuit of strategic alternatives.

*    NEGOTIATIONS WITH AZI LLC. The Special Committee considered the history of
     negotiations with respect to the Agreement and Plan of Merger and the
     transactions contemplated thereby as the product of arm's-length
     negotiations between AZI LLC and the Special Committee. See "SPECIAL
     FACTORS--Background of the Merger" and "THE AGREEMENT AND PLAN OF MERGER."

*    FINANCING COMMITMENTS. The Special Committee considered the commitment
     letters received by AZI LLC from Imperial Bank and Arizona MultiBank to
     arrange, fund and administer certain of the financing for the Merger. The
     Special Committee and its advisors reviewed the terms and conditions of,
     and were satisfied with, such commitment letters.

*    COMPARISON TO OTHER PROPOSALS. The Special Committee, together with its
     advisors, evaluated the viability of the indications of interest received
     by the Special Committee during its process and the relative strength of
     the AZI LLC proposal when compared to all other proposals and concluded
     that the AZI LLC proposal was stronger than each of the other proposals in
     substantially all respects, including the viability and certainty of the
     financing structure and Arizona Instrument's ability to negotiate
     representations and warranties, covenants, conditions and other provisions
     in the Agreement and Plan of Merger which are substantially more favorable
     to Arizona Instrument's shareholders than those which would have been
     available in a transaction with an unaffiliated third party. Accordingly,
     the Special
<PAGE>
     Committee believed that it was not likely that any party other than AZI LLC
     and the Founders would propose and complete a transaction on terms more
     favorable to Arizona Instrument's shareholders than the Merger.

*    OTHER POTENTIAL BUYERS. The Special Committee believed that the length of
     time between the public announcement of the fact that Arizona Instrument
     was considering strategic alternatives and the date of the Agreement and
     Plan of Merger provided a substantial amount of time within which to gauge
     the current level of interest in Arizona Instrument and to permit potential
     buyers to come forward. The Special Committee also considered the
     provisions of the Agreement and Plan of Merger which legally and
     practically permit Arizona Instrument to respond meaningfully to third
     party proposals for alternative transactions. Specifically, the terms of
     the Agreement and Plan of Merger authorize Arizona Instrument under certain
     circumstances to (1) engage in negotiations with third parties who submit
     in writing an acquisition proposal for a transaction which, among other
     things, the Special Committee determines in good faith is as or more likely
     to occur than the Merger and would be more favorable to the shareholders of
     Arizona Instrument and (2) terminate the Agreement and Plan of Merger in
     order to permit Arizona Instrument to enter into such a transaction with
     only a modest break-up fee (AZI LLC'S out-of-pocket expenses incurred after
     January 31, 2000, but not more than $100,000). See "--Negotiations with AZI
     LLC," above and "THE AGREEMENT AND PLAN OF MERGER--Acquisition Proposals."

*    SPECIAL COMMITTEE COMPOSITION AND RETENTION OF ADVISORS. The Special
     Committee considered that it was composed of disinterested directors, none
     of whom were employed by or affiliated with Arizona Instrument (except in
     their capacities as directors) or would have any equity interest in the
     Surviving Company. The Special Committee also considered that it had
     retained and was advised by its own financial advisor who assisted the
     Special Committee in evaluating the fairness of the proposed transactions.

*    REGULATORY APPROVALS. The Special Committee considered that there are no
     regulatory approvals required to consummate the Merger.

*    AVAILABILITY OF DISSENTERS' RIGHTS. The Special Committee considered that
     dissenters' rights of appraisal will be available to the holders of common
     stock under Delaware law.

*    LOSS OF EQUITY INTEREST. The Special Committee considered the fact that if
     the Agreement and Plan of Merger is approved, the holders of the common
     stock will not participate in the future growth of Arizona Instrument.
     Because of the risks and uncertainties associated with Arizona Instrument's
     future prospects, the Special Committee concluded that the Merger was
     preferable to enabling the holders of such stock to have a speculative
     potential future return.

*    INTERESTS OF CERTAIN PARTIES. The Special Committee also recognized that
     the Founders would have an opportunity, subject to the risks of the
     Surviving Company's business, to benefit from any increases in the value of
     the Surviving Company following the Merger. The Special Committee
     recognized that this represented a potential conflict between the interests
     of the Founders and Arizona Instrument's other shareholders. However, the
     Special Committee considered its assessment of the risks associated with
     Arizona Instrument's future and recognized that under the terms of the
     Agreement and Plan of Merger, the Founders would assume all business and
     investment risks associated with the Surviving Company. The Special
     Committee considered that the assumption of risk involved in the proposed
     transaction mitigated the potential conflict of interest.

     The foregoing discussion of the information and factors discussed by the
Special Committee is not meant to be exhaustive, but includes all material
factors considered by the Special Committee to support their decision to
recommend the approval of the Agreement and Plan of Merger and to determine that
the transactions contemplated thereby are fair to, and in the best interests of,
Arizona Instrument and the holders of Arizona Instrument's common stock (other
than AZI LLC and its affiliates). The Special Committee did not assign relative
weights or additional quantifiable values to the above factors; rather, the
Special Committee viewed its position and recommendations as being based on the
totality of the information presented to and considered by the members. Certain
factors which might be considered when evaluating a transaction similar to the
Merger were not considered by the Special Committee. These factors include
whether the Merger Consideration offered to the holders of Arizona Instrument's
common stock (other than AZI LLC and its affiliates) constitutes fair value in
relation to (1) liquidation value or net book value, which factors were not
considered because these factors are not indicative of the value of Arizona
Instrument as a going concern, or (2) the prices paid by Arizona Instrument or
any of the Founders in connection with purchases of Arizona Instrument common
stock by any of such persons during the last two full fiscal years of Arizona
<PAGE>
Instrument, which factor was not considered because no significant purchases of
such kind were made during the last two full fiscal years.

Board of Directors of Arizona Instrument

     The Board of Directors unanimously formed the Special Committee to act
solely on behalf of the unaffiliated shareholders of Arizona Instrument for
purposes of negotiating the Agreement and Plan of Merger. The Special Committee,
in turn, retained Peacock Hislop to prepare and deliver an opinion as to the
fairness of the Merger Consideration to Arizona Instrument's shareholders (other
than AZI LLC and its affiliates) from a financial point of view.

     In reaching its determination referred to above, the Board of Directors
considered, relied upon and adopted the Special Committee's conclusions,
recommendations, unanimous approval of the Agreement and Plan of Merger,
declaration of the Agreement and Plan of Merger's advisability and Peacock
Hislop's opinion (which opinion expressly permitted reliance thereon by the
Board of Directors) that, as of the date of such opinion, based upon and subject
to various considerations, assumptions and limitations stated therein, the $5.00
per share in cash to be received by Arizona Instrument's shareholders in the
Merger was fair to such shareholders (other than AZI LLC and its affiliates)
from a financial point of view, and the related analyses presented by Peacock
Hislop.

     In addition, Arizona Instrument undertook the transaction with AZI LLC at
this time as a result of (1) the Special Committee's consideration of the
factors outlined above relating to the limitations of Arizona Instrument as a
public company, the inconsistent results of Arizona Instrument's operations and
its recent financial performance and the impact of such performance on future
prospects and the long-standing concerns of the Board of Directors (including
the disinterested members comprising the Special Committee) regarding the
continuing depressed stock price of Arizona Instrument's common stock, (2) the
lack of investor interest in Arizona Instrument on the part of third parties and
(3) each of the other factors considered by the Special Committee and described
above.

     The Board of Directors believes that sufficient procedural safeguards to
ensure fairness of the transaction and to permit the Special Committee to
effectively represent the interests of the holders of Arizona Instrument's
common stock (other than AZI LLC and its affiliates) were present. The Board of
Directors reached this conclusion in view of (1) the unaffiliated status of the
members of the Special Committee whose sole purpose was to represent the
interests of the holders of Arizona Instrument's common stock (other than AZI
LLC and its affiliates); (2) retention by the Special Committee of independent
financial advisors; and (3) the fact that the Special Committee, even though
consisting of directors of Arizona Instrument and therefore not completely
unaffiliated with Arizona Instrument, is a mechanism well recognized under
Delaware law to provide for fairness in transactions of this type.

     THE BOARD OF DIRECTORS BELIEVES THAT THE MERGER IS ADVISABLE AND IS FAIR
TO, AND IN THE BEST INTERESTS OF, ARIZONA INSTRUMENTS AND THE HOLDERS OF COMMON
STOCK (OTHER THAN AZI LLC AND ITS AFFILIATES) AND, BASED UPON THE UNANIMOUS
RECOMMENDATION OF THE SPECIAL COMMITTEE, RECOMMENDS APPROVAL OF THE AGREEMENT
AND PLAN OF MERGER AND THE TRANSACTIONS CONTEMPLATED THEREBY TO ARIZONA
INSTRUMENT'S SHAREHOLDERS.

Opinion of Financial Advisor to the Special Committee

     The Special Committee retained Peacock Hislop to act as financial advisor
to render an opinion as to the fairness of the proposed transaction, from a
financial point of view, to Arizona Instrument's public shareholders. Prior to
being engaged as the financial advisor to the Special Committee, Peacock Hislop
had no prior professional relationship with Arizona Instrument. Peacock Hislop
was selected by the Special Committee based on its experience as financial
advisor in the evaluation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive bidding,
secondary distribution of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes.

     At the request of the Special Committee, on March 28, 2000, Peacock Hislop
rendered its oral opinion to the Special Committee and the Board of Directors to
the effect that, as of that date and subject to the assumptions made, matters
considered and limits of the review undertaken by Peacock Hislop described in
its opinion, the $5.00 merger consideration to be received by Arizona Instrument
shareholders other than AZI LLC or its affiliates pursuant to the Merger was
<PAGE>
fair from a financial point of view to such shareholders. Peacock Hislop
subsequently confirmed this opinion in writing by letter dated March 28, 2000.

     The full text of Peacock Hislop's written opinion is attached as Appendix B
to this proxy statement. We refer you to Peacock Hislop's opinion, and you
should consider it as part of this proxy statement since we are incorporating it
by this reference. The following description of Peacock Hislop's opinion is only
a summary of it, and you should read the full opinion for a complete
understanding of the opinion's assumptions, considerations and limitations.
Copies of the written opinion are also available for inspection and copying at
the principal executive offices of Arizona Instrument during regular business
hours by any interested shareholder of Arizona Instrument, or a representative
who has been so designated in writing, and may be inspected and copied, or
obtained by mail, by written request directed to: Corporate Secretary, Arizona
Instrument Corporation, 1912 West 4th Street, Tempe, Arizona 85281.

     You should be aware that the Peacock Hislop opinion only advises the
Special Committee and the Board of Directors concerning the fairness from a
financial point of view of the merger consideration. The opinion does not
address the merits of our Board of Directors' decision to approve the Merger.
The opinion is not a recommendation to you that you vote for or against the
Merger or that you take any other action regarding the Merger.

     In preparing its opinion, Peacock Hislop, among other things:

     *    reviewed a draft of the Agreement and Plan of Merger;
     *    reviewed certain of our publicly available financial statements and
          other business and financial information;
     *    reviewed certain of our internal financial statements, financial
          forecasts and other data concerning Arizona Instrument prepared by our
          management, including Mr. Hays' projections (the "Hays Projections");
     *    met with certain members of our management to discuss Arizona
          Instrument's business, historical and projected financial results,
          financial condition and future prospects;
     *    reviewed the historical stock price and trading volume for Arizona
          Instrument common stock;
     *    compared our financial performance and the price and trading volume of
          Arizona Instrument common stock with that of other publicly traded
          companies in similar lines of business;
     *    compared the financial terms of the Merger with the financial terms of
          certain other transactions that Peacock Hislop deemed comparable;
     *    prepared a discounted cash flow analysis and a leveraged acquisition
          analysis of Arizona Instrument;
     *    made other studies and inquiries, and took into account other matters
          and special factors that Peacock Hislop believed were relevant to
          forming its opinion, including an assessment of general economic and
          market conditions.

     Peacock Hislop did not independently verify any of the information it
obtained for purposes of its opinion. Instead, Peacock Hislop assumed the
accuracy and completeness of all such information. Peacock Hislop relied upon
our management's information and forecasts concerning our prospects, including
the Hays Projections, and assumed they were reasonably prepared on bases
reflecting the best currently available judgments and estimates of management as
to our likely future financial performance and that such forecasts, including
the Hays Projections, will be realized at the times contemplated therein. As to
all legal matters, Peacock Hislop relied on the advice of counsel to the Special
Committee and has assumed that the Merger will be consummated in accordance with
the terms of the Agreement and Plan of Merger. Peacock Hislop did not make an
independent inspection, evaluation or appraisal of the assets or liabilities of
Arizona Instrument, nor did anyone furnish Peacock Hislop with any such
evaluation or appraisal. The Peacock Hislop opinion is based on market, economic
and other conditions as they existed and could be evaluated at the time the
opinion was given.

     No limitations were imposed by Arizona Instrument, the Special Committee or
the Board of Directors on the procedures Peacock Hislop followed in rendering
its opinion. However, Peacock Hislop was not engaged or authorized to solicit
and did not solicit any other business combination transaction or strategic
transaction as an alternative to the Merger. The solicitation process was
conducted by the Special Committee. The Special Committee conducted its own
solicitation process in an effort to attract third parties' interest in
acquiring all or any part of Arizona Instrument, in which Peacock Hislop took no
part. The Special Committee informed Peacock Hislop that Mr. Hays' offer was the
only offer received that was deemed to be an acceptable firm offer by the
<PAGE>
Special Committee. Peacock Hislop has not been asked to, and has not, rendered
an opinion as to the fairness of the solicitation process conducted by the
Special Committee.

     In addressing the fairness, from a financial point of view, of the merger
consideration to be received by the unaffiliated shareholders of Arizona
Instrument, Peacock Hislop employed a variety of generally recognized valuation
methodologies and performed those, which it believed were most appropriate for
developing its opinion. The preparation of a fairness opinion involves various
determinations of the most appropriate and relevant methods of financial
analysis and the application of those methods to the particular circumstances.
Therefore, such an opinion is not readily susceptible to partial analysis or
summary description. In arriving at its opinion, Peacock Hislop did not
attribute any particular weight to any analysis or factor considered by it, but
rather made qualitative judgments about the significance and relevance of each
analysis and factor. Such analysis resulted in the calculation of ranges of
implied per share values for Arizona Instrument common stock.

     Peacock Hislop believes that its analyses must be considered as a whole and
that selecting portions of its analyses, without considering all factors and
analyses, would create an incomplete view of the process underlying its opinion.

     In performing its analyses, Peacock Hislop made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Arizona Instrument. The
analyses performed by Peacock Hislop do not purport to be an appraisal and are
not necessarily indicative of actual values, trading values or actual future
results that might be achieved, all of which may be significantly more or less
favorable than suggested by Peacock Hislop's analyses. No public company that
Peacock Hislop utilized as a comparison is identical or directly comparable to
Arizona Instrument, and none of the comparable transactions utilized as a
comparison is identical or directly comparable to the Merger. Accordingly, a
purely mathematical analysis based on such comparable companies or comparable
business combinations is not a meaningful method of using the relevant data;
rather, these analyses involve complex considerations and judgments concerning
differences in financial and operating characteristics and other factors that
could affect the transaction, public share trading or other values of the
companies that are being compared.

     In connection with its analyses, Peacock Hislop utilized estimates and
forecasts of our future operating results contained in or derived from the Hays
Projections. Analyses based on forecasts of the future results are not
necessarily indicative of actual future results, which may be significantly more
or less favorable than the forecasts. The analyses are inherently subject to
uncertainty being based on numerous factors or events beyond the control of
Arizona Instrument. Therefore, future results or actual values may be materially
different from these forecasts or assumptions. The Peacock Hislop opinion was
one of many factors taken into consideration by the Special Committee in making
its determination to approve the Agreement and Plan of Merger. Consequently, the
analyses described below should not be viewed as determinative of the opinion of
either the Special Committee or the Board of Directors with respect to the value
of Arizona Instrument or whether the Special Committee or the Board of Directors
would have been willing to agree to different terms for the Merger.

     The following is a brief summary of the material analyses performed by
Peacock Hislop in connection with rendering the Peacock Hislop opinion to the
Special Committee and the Board of Directors. The following summary includes
information presented in tabular form. In order to understand the financial
analyses performed by Peacock Hislop, the tables must be read together with the
accompanying text. The per share values presented in the analyses below did not
take into account all of the transaction expenses expected to be incurred in the
Merger. Also, for purposes of the financial analyses from which these per share
values are derived, Peacock Hislop assumed that we would be operated by a
management team with the perceived ability to achieve the financial results of
the Hays Projections. The following analyses reflect substantially the same
methodologies used by Peacock Hislop in its presentations to the Special
Committee on March 28, 2000.

Comparable Public Company Analyses

     Peacock Hislop reviewed and compared the financial stock market performance
of Arizona Instrument and certain ratios and multiples of Arizona Instrument to
the financial and stock market performance and corresponding ratios and
multiples of nine publicly held companies in the analytical instruments industry
that Peacock Hislop believed were generally comparable to Arizona Instrument.
The companies were CEM Corporation, O.I. Corporation, Mesa Laboratories, Sierra
<PAGE>
Monitor Corporation, Metrisa Inc., Lifschultz Industries Inc., Transmation Inc.,
Intelligent Controls Inc., and MOCON, Inc. (collectively the "Comparable
Companies").

     Among other analyses, Peacock Hislop calculated the total invested capital
(that is, equity market value, plus debt, less cash and equivalents, or "TIC")
as a multiple of the last twelve months' revenues, operating income (earnings
before interest and taxes or "EBIT" ), operating cash flow (that is, operating
income plus depreciation and amortization, or "EBITDA"), debt-free net income
and net income for each of the Comparable Companies. All multiples were
calculated using closing stock prices on February 23, 2000. A summary of the TIC
multiples generated from this analysis is shown in the following table:

                        TOTAL INVESTED CAPITAL MULTIPLES

<TABLE>

</TABLE>

     Peacock Hislop selected the Comparable Companies because they have general
business, operating and financial characteristics generally similar to those of
Arizona Instrument. Peacock Hislop noted that no company used in the forgoing
analysis is identical or directly comparable to Arizona Instrument and that the
multiples shown in the forgoing table that are above the median multiples relate
to companies that have had higher internal growth rates and have a much larger
market capitalization than Arizona Instrument. Accordingly, Peacock Hislop
deemed the low multiples derived in the foregoing analysis to be most relevant.

     Peacock Hislop calculated the implied equity value per share by applying
the multiples derived from the Comparable Companies (as illustrated in the table
above) to the same last twelve month ("LTM") financial data of Arizona
Instrument. The cash outstanding of $3,471,429 as of December 31, 1999, was then
added back and the resulting values divided by the numbers of shares outstanding
as of December 31, 1999. The following table presents the results of this
analysis:

Comparable Transaction Analysis

     Peacock Hislop reviewed and compared the publicly available financial data
related to twelve business combination transactions in the analytical
instruments industry that Peacock Hislop felt were generally comparable to the
Merger and that disclosed information sufficient to provide valuation guidance
(collectively, the "Comparable Transactions"). A list of Comparable Transactions
follows:

                                TRANSACTION DATA

Acquiror Name                   Target Name                      Date Effective

Hickok Inc.                     Waekon Industries, Inc.             02/17/98

     Among other analyses, Peacock Hislop calculated enterprise values relative
to each of the Comparable Transaction companies' revenues, operating income and
operating cash flow. A summary of the enterprise value multiples generated from
this analysis is shown in the following table:
<PAGE>
                         VALUE OF TRANSACTION MULTIPLES

Average Multiple Including high and low       0.9x        6.1x           5.2x
Median Multiple Including high and low        0.6x        5.3x           4.5x
Average Multiple Excluding high and low       0.8x        6.0x           5.2x
Median Multiple Excluding high and low        0.6x        5.3x           4.4x

     Peacock Hislop chose the Comparable Transactions because the target
companies have general business, operating and financial characteristics similar
to those of Arizona Instrument. However, Peacock Hislop noted that no company or
transaction used in the foregoing analysis is identical or directly comparable
to Arizona Instrument or the Merger and that the Comparable Transactions include
three transactions with very high valuation multiples in which the consideration
for the acquisitions was all stock and the transactions were accounted for using
the pooling of interests method to which Peacock Hislop applied a 30%
marketability discount (restricted stock). Peacock Hislop also noted that a
number of the acquired companies in the Comparable Transactions were
substantially larger than Arizona Instrument. Therefore, Peacock Hislop deemed
the low multiples derived in the foregoing analysis to be most relevant.

     Peacock Hislop estimated Arizona Instrument's excess cash amounts to be
$2,900,000 or $2.12 per share ("Excess Cash") based on a historical analysis of
minimum cash requirements and Mr. Hays' estimated minimum cash needs in the Hays
Projections.

     Peacock Hislop calculated the implied equity value per share by applying
the multiples derived from the Comparable Transactions (as illustrated in the
table above) to the same last twelve month financial data of Arizona Instrument.
The estimated excess cash outstanding of $2,900,000 as of December 31, 1999, was
then added back and the resulting values were divided by the number of shares
outstanding as of December 31, 1999. The following table presents the results of
this analysis:

Median Multiple Excluding high and low       $5.78        $5.06         $6.08

Discounted Cash Flow Analysis

     Peacock Hislop performed a discounted cash flow analysis of the projected
unlevered free cash flows of Arizona Instrument (defined as cash flow available
after changes in working capital, capital spending and tax obligations) for the
period of 2000 through 2004 and the terminal value for the years beyond the
projections based on a multiple of 2004 projected cash flow. Peacock Hislop
based its range of terminal value multiples on, among other things, its review
of the Comparable Companies and the Comparable Transactions. Peacock Hislop
based this analysis on the Hays Projections, without any discounts or
adjustments to those projections, and a range of discount rates and terminal
values to determine the theoretical present value of the entire company. Peacock
Hislop arrived at a range of discount rates by calculating an estimated cost of
capital for Arizona Instrument using, among other things, the estimated cost of
capital and capital structures of companies in Arizona Instrument's industry as
determined according to Arizona Instrument's Standard Industry Classification
code by a recognized source. The cost of capital in the case of Arizona
Instrument is a function of its cost of equity. The cost of equity was estimated
using the Capital Asset Pricing Model ("CAPM") a commonly used formula to
estimate the cost of equity of companies. CAPM is calculated by adding an
estimated risk-free rate of return to the product of an estimated market risk
premium and an estimated company beta (company volatility versus the market as a
whole) plus a small company risk premium and an unsystematic risk premium.
<PAGE>
     For each of the scenarios, the discounted cash flow analysis of Arizona
Instrument was determined by adding the present value, as of December 31, 1999,
of projected free cash flows through December 31, 2004, plus the estimated value
of Arizona Instrument as of December 31, 2004, using a range of terminal
multiples of EBIT in one case and EBITDA in the other.

     The range of estimated values for Arizona Instrument at the end of the
five-year period was calculated by applying the calculated discount rates
ranging from 19.3% to 23.3% and terminal value multiples of estimated operating
cash flow in 2004 ranging from 6.0x to 8.0x, when based on EBIT multiples, and
5.0x to 7.0x, when based on EBITDA multiples. The following table presents a
summary of the implied equity values per share of Arizona Instrument common
stock after adding back excess cash from this analysis:

     Peacock Hislop calculated the theoretical implied equity per share value of
Arizona Instrument's common stock to range from $4.62 to $6.41.

Leveraged Recapitalization Analysis

     Peacock Hislop performed a leveraged recapitalization analysis to determine
the potential implied equity value per share of Arizona Instrument Common Stock
that might be achieved in an acquisition of Arizona Instrument in a leveraged
recapitalization transaction based on current market conditions. In conducting
this analysis, Peacock Hislop utilized the Hays Projections, without any
discounts or adjustments to those projections, and assumed that financing for
the Merger could be obtained in the high yield and bank finance markets in an
amount not in excess of a certain multiple of the EBITDA for the last twelve
months and equal to AZI LLC's proposed financing from its own lenders and that a
minimum internal rate of return ranging from 35% to 45% on equity invested
during a five-year period would be required by the acquirer. This analysis
resulted in an estimated implied equity value per share of Arizona Instrument
Common Stock on a leveraged recapitalization basis of approximately $5.50 to
$5.87.

Other Analyses Performed And Factors Considered

     Peacock Hislop reviewed Arizona Instrument's historical stock price and
volume, estimated trading volumes at different stock prices and the weighted
average stock price for different periods of time. Peacock Hislop also reviewed
the historical trading volume of the Comparable Companies. Peacock Hislop
compared the Merger consideration to Arizona Instrument's pre-merger stock price
and estimated volume-weighted average stock price and calculated the premium of
the merger consideration to each as follows:

     *    38 percent premium to the stock price the day prior to the public
          announcement of Mr. Hays' $5.00 per share indication of interest
          letter.
     *    41 percent premium of Arizona Instrument's estimated volume-weighted
          average stock price for the 12 months prior to the public announcement
          of Mr. Hays' $5.00 per share indication of interest letter.
     *    21 percent premium to the stock price the day prior to the public
          announcement of Arizona Instrument's pursuit of strategic
          alternatives.
     *    94 percent premium to Arizona Instrument's estimated volume-weighted
          average stock price for the six months prior to the public
          announcement of Arizona Instrument's pursuit of strategic
          alternatives.
     *    70 percent premium to Arizona Instrument's estimated volume-weighted
          average stock price for the three months prior to the public
          announcement of Arizona Instrument's pursuit of strategic
          alternatives.

     Peacock Hislop used estimated volume-weighted average stock prices in order
to consider the differences in daily trading volumes in Arizona Instrument's
stock in analyzing the historical prices of Arizona Instrument's stock.

     In rendering its opinion, Peacock Hislop also discussed with Arizona
Instrument's management their expectations as to financial performance during,
and financial position near the end of, the fiscal quarter ending March 31,
2000. However, Peacock Hislop determined that management's expectations as to
the financial results for such quarter did not affect its conclusions, which
were based on analyses using published financial data through the quarter ended
December 31, 1999.

     Peacock Hislop also considered a number of outside factors that could
substantially impact the value of Arizona Instrument. The most significant ones
were the potential environmental liability relating to a sold business line, the
tax benefits of capital gain treatment versus ordinary income from an
extraordinary dividend distribution to Arizona Instrument shareholders, the
product line obsolescence risk and the lack of third party interest in the
company.

     After applying the above described valuation methodologies, Peacock Hislop
concluded that the value of Arizona Instrument, when valuing the Company as a
whole, was approximately $5.50 per share or $7,543,000 in total from a
quantitative standpoint. However, Peacock Hislop believes that the special
factors mentioned above represent significant risk in the valuation and, while
subjective and not quantifiable, should properly be valued at not less than
$0.50 per share. Based upon and subject to the foregoing, Peacock Hislop is of
the opinion that, as of March 28, 2000, the Merger Consideration is fair, from a
financial point of view, to the shareholders of Arizona Instrument (other than
AZI LLC and its affiliates).

     The information above is a brief summary of the material financial analyses
presented by Peacock Hislop to Arizona Instrument's Special Committee on March
28, 2000. This summary does not purport to be a complete description of the
analyses performed by Peacock Hislop in connection with the rendering of the
Peacock Hislop opinion. The preparation of a fairness opinion is a complex
analytical process involving various qualitative judgments as to the most
appropriate and relevant methods of financial analysis and the application of
those methods to particular circumstances and is not susceptible to partial
analysis or summary description. Peacock Hislop believes that its analyses must
be considered as a whole and that selecting portions of its analyses, without
considering all factors and analyses, would create an incomplete view of the
process underlying Peacock Hislop's opinion. In addition, Peacock Hislop
considered the significance and relevance of the results of every portion of its
analyses and did not assign relative weights to any portion of its analyses, so
that the ranges of valuations resulting from any particular analysis described
above should not be taken to be Peacock Hislop's view of the actual value of
Arizona Instrument.

Projections

     As discussed above, Mr. Hays prepared the Hays Projections with respect to
Arizona Instrument's financial performance over a five-year period ending
December 31, 2004. The Hays Projections were provided to Mr. Hays' potential
sources of funding to finance the Merger. In addition, the Hays Projections were
provided to Peacock Hislop and included in the material provided to every other
potential acquirer that executed a confidentiality agreement. The Hays
Projections were also used by Peacock Hislop in analyzing the value of Arizona
Instrument. The following is a summary of the Hays Projections:

                                          FISCAL YEAR ENDING DECEMBER 31,
(in 000's)
                         2000      2001       2002       2003       2004
                         ----      ----       ----       ----       ----
Total Revenues          $9,019    $9,526    $10,223    $11,098    $12,070
Costs of Goods Sold     $3,344    $3,564    $ 3,828    $ 4,159    $ 4,527
Gross Profit            $5,675    $5,962    $ 6,395    $ 6,939    $ 7,543
Operating Expenses      $4,524    $4,770    $ 5,108    $ 5,333    $ 6,004
EBITDA                  $1,151    $1,192    $ 1,287    $ 1,406    $ 1,539
Capital Expenditures    $  300    $  300    $   300    $   300    $   300

     Arizona Instrument does not as a matter of course make public any
projections as to the future performance or earnings, and the projections set
forth above are included in this proxy statement only because the information is
available to Mr. Hays. The Hays Projections were not prepared with a view to
public disclosure or compliance with the published guidelines of the Commission
or the guidelines established by the American Institute of Certified Public
Accountants regarding projections or forecasts. The Hays Projections are
subjective in many respects and are thus susceptible to various interpretations
and periodic revision based on actual experience and business developments. The
Hays Projections were based on a number of assumptions that are beyond the
control of Arizona Instrument, Mr. Hays or their respective financial advisors,
including economic forecasting (both general and specific to Arizona
Instrument's business), which is inherently uncertain and subjective. None of
Arizona Instrument, Mr. Hays or their respective financial advisors assumes any
responsibility for the accuracy of the Hays Projections. The inclusion of the
Hays Projections should not be regarded as an indication that Arizona
Instrument, Mr. Hays, Peacock Hislop or any other person who received the Hays
Projections considers them an accurate prediction of future events. Neither Mr.
Hays nor Arizona Instrument intends to update, revise or correct the Hays
Projections if they become inaccurate (even in the short term). Nevertheless,
for the purpose of this valuation, Peacock Hislop assumed that the Hays
Projections would be realized at the times contemplated therein.

     Pursuant to its Engagement Letter ("Engagement Letter") with Peacock Hislop
dated February 1, 2000, Arizona Instrument agreed to pay to Peacock Hislop an
aggregate fee of $50,000 for its services in connection with the Fairness
Opinion. The Engagement Letter also provides that Arizona Instrument will
reimburse Peacock Hislop for its reasonable travel, legal and other
out-of-pocket expenses incurred in connection with Peacock Hislop's role
thereunder and will indemnify Peacock Hislop and its affiliates from and against
certain liabilities. These liabilities include liabilities under the federal
securities laws in connection with the engagement of Peacock Hislop by the
Special Committee. Peacock Hislop will earn no other fees, contingent or
otherwise, in connection with this Merger.

     The Special Committee retained Peacock Hislop on the basis of its
experience with mergers and acquisitions, financing and advising Boards of
Directors and shareholders regarding strategic alternatives. Peacock Hislop is
regularly engaged in the valuation of businesses and their securities in
connection with mergers, acquisitions, and private placement of securities.
Peacock Hislop is a privately owned investment banking firm, which has been an
NASD registered broker-dealer since 1990. In the ordinary course of its
business, Peacock Hislop may, from time to time, trade in the securities of
Arizona Instrument for its own account or the accounts of its customers and,
accordingly, may at any time hold long or short positions in our securities.

AZI LLC's Purpose and Reason for the Merger

     The purpose of AZI LLC and the Founders in proceeding with the Merger is to
acquire the entire equity interest of Arizona Instrument in a leveraged
transaction providing fair value to Arizona Instrument's unaffiliated
shareholders. The reasons for AZI LLC and the Founders to proceed with the
Merger include:
<PAGE>
     *    Reasonable cost of the transaction;

     *    The Founders' belief that overall value can be enhanced by focusing on
          stakeholders in the business rather than only shareholders;

     *    Lack of investor interest in Arizona Instrument;

     *    Elimination of the expense burden of being a public company;

     *    Ability to finance the transaction; and

     *    Availability of and the need to retain a successful team of skilled
          employees.

     The transactions contemplated by the Agreement and Plan of Merger, however,
will involve a substantial risk to the Founders because of the large amount of
indebtedness to be incurred in connection with the consummation of the Merger.

     The acquisition of the entire equity interest in Arizona Instrument was
structured as a cash merger in order to accomplish the acquisition in a single
step, without the necessity of financing separate purchases of shares in a
tender offer or in open market purchases. The transactions also were structured
so as not to disrupt contracts with third party providers such as lessors, phone
service companies and the like.

     Each of the Founders and AZI LLC has concluded that the Merger, including
the merger consideration of $5.00 per share in cash and the terms and conditions
of the Agreement and Plan of Merger, are fair to the Arizona Instrument
shareholders (other than AZI LLC and its affiliates) based upon, among other
things, the following factors:

     *    the conclusions and recommendations of the Special Committee and the
          Board of Directors;

     *    the Special Committee, consisting of disinterested directors who are
          not affiliated with AZI LLC or the Founders, had unanimously approved
          the Merger and recommended that the shareholders approve and adopt the
          Agreement and Plan of Merger and the transactions contemplated
          thereby;

     *    the merger consideration and the other terms and conditions of the
          Agreement and Plan of Merger were the result of arm's-length, good
          faith negotiations between the Special Committee and the Founders and
          their respective advisors;

     *    Peacock Hislop issued an opinion to the Special Committee to the
          effect that, as of the date of such opinion, based upon and subject to
          various considerations, assumptions and limitations stated therein,
          the$5.00 per share in cash to be received in the Merger was fair to
          the Arizona Instrument shareholders (other than AZI LLC and its
          affiliates) from a financial point of view; and

     *    the terms of the Agreement and Plan of Merger authorize Arizona
          Instrument under certain circumstances to (1) engage in negotiations
          with, and provide access to information about Arizona Instrument to,
          third parties who submit in writing an acquisition proposal for a
          transaction which, among other things, the Special Committee
          determines would be more favorable to the shareholders of Arizona
          Instrument than the Merger and (2) terminate the Agreement and Plan of
          Merger in order to permit Arizona Instrument to enter into such
          transaction.

Interests of Certain Persons in the Merger; Certain Relationships

     In considering the recommendation of the Special Committee and the Board of
Directors with respect to the Merger, shareholders should be aware that certain
members of the Board of Directors and of Arizona Instrument's management have
interests that may present actual, potential, or the appearance of potential,
conflicts of interest in connection with the Merger. The Special Committee and
the Board of Directors were aware of these potential or actual conflicts of
<PAGE>
interest and considered them along with other matters described under "Special
Factors--Recommendation of the Special Committee and Board of Directors;
Fairness of the Merger."

Retained Equity Interest

     The Founders beneficially own an aggregate of 49,188 shares of common
stock, representing approximately 4% of the total outstanding shares of common
stock. In addition, the Founders hold options to purchase an aggregate of 66,000
shares of common stock at exercise prices ranging from $2.75 to $9.05 per share.

     The Founders will, prior to the Effective Time (as defined herein),
contribute to AZI LLC certain cash amounts in consideration of the issuance of
membership units of AZI LLC. Upon consummation of the Merger, the Founders will
collectively beneficially own 100% of the outstanding membership units of the
Surviving Company. Such ownership will arise from the cancellation, upon the
consummation of the Merger, of all of the outstanding shares of common stock of
Arizona Instrument.

     None of the members of the Special Committee will contribute any cash or
shares of common stock or other equity interests in Arizona Instrument to AZI
LLC nor will any member of the Special Committee own any interest in AZI LLC or
the Surviving Company following the effective time of the Merger.

     The value of Arizona Instrument stock and stock options held by members of
the Special Committee to be received upon consummation of the Merger is as
follows:


                                Number                 Number of
Name                           of Shares    Value    Stock Options    Net Value
- ----                           ---------    -----    -------------    ---------
S. Thomas Emerson, Ph.D.        4,000      $20,000      9,500          $5,950
Steven G. Zylstra                 120      $   600      7,000          $5,059

Management of the Surviving Company

     The Agreement and Plan of Merger provides that the current Manager of AZI
LLC shall be the Manager of the Surviving Company immediately after the Merger.

     AZI LLC currently does not expect to enter into new employment or other
agreements with any person prior to the Merger, although agreements to which
Arizona Instrument is a party that are currently in effect will become
obligations of the Surviving Company. The Agreement and Plan of Merger provides
that the Surviving Company will, for a period of six years after the Effective
Time, maintain all rights to indemnification and limitations on liability in
favor of the former officers and directors of Arizona Instrument to the same
extent and upon the terms and conditions provided in Arizona Instrument's
certificate of incorporation, bylaws and indemnification agreements as in effect
on the date of the Agreement and Plan of Merger. The Agreement and Plan of
Merger also provides that the Surviving Company will maintain its existing (or
appropriate substitute) policies of directors' and officers' liability insurance
and fiduciary liability insurance for a period of six years after the Effective
Time, subject to certain limitations. See "The Agreement and Plan of
Merger--Covenants." The Agreement and Plan of Merger also provides that, for a
period of at least one year following the Effective Time, the Surviving Company
will maintain employee benefit plans and arrangements (other than equity
incentive arrangements) which provide benefits substantially comparable in the
aggregate for each employee to the benefits provided by Arizona Instrument as of
March 31, 2000.

Management Employment Agreements

     Effective January 1, 1998, the Company entered into an employment agreement
with George G. Hays pursuant to which Mr. Hays agreed to serve as President and
Chief Executive Officer. The agreement provides for a base annual salary of
$165,000, subject to merit increases, plus an annual incentive bonus of at least
30% of annual salary based on an incentive bonus plan administered by the Board
of Directors. Mr. Hays is also entitled to participate in any benefit
arrangements available to executive officers of the Company. Upon termination of
the employment agreement without cause, Mr. Hays is entitled to receive an
amount equal to the compensation due him over the balance of the term of the
<PAGE>
employment agreement, and to participate in applicable benefit programs for the
balance of the term of the employment agreement. The agreement terminates on
March 31, 2000, and will automatically renew for additional one-year terms until
notice of non-renewal by the Company. This agreement replaces Mr. Hays' previous
employment agreement with the Company dated April 1, 1997, pursuant to which he
was employed as Vice President and Chief Financial Officer. The Company amended
and renewed Mr. Hays' employment agreement and extended it through March 31,
2001.

AZI LLC Member Agreements

     George G. Hays and Chez & Schwartz Inc. Profit Sharing Plan dated December
19, 1973, an affiliate of Mr. Harold D. Schwartz, are parties to a Member
Agreement dated March 21, 2000 that prohibits the transfer of the membership
units owned by Mr. Hays and Chez & Schwartz, unless transferred pursuant to the
Member Agreement. The Member Agreement provides that upon the death of Mr.
Schwartz or 5 years from the date of the Member Agreement, Mr. Hays has the
right to purchase the membership units of AZI LLC owned by Chez & Schwartz for a
price determined by a specified formula and 5 years from the date of the Member
Agreement Chez & Schwartz has the right to require Mr. Hays to purchase the
membership units of AZI LLC owned by Chez & Schwartz for a price determined by a
specified formula. The Member Agreement also provides that if Mr. Hays proposes
to sell any of his membership units of AZI LLC, then Chez & Schwartz may
participate in Mr. Hays proposed sale and sell certain of its membership units
of AZI LLC on the same terms as Mr. Hays proposes to sell his membership units
of AZI LLC.

     George G. Hays and The Hays Family Revocable Lifetime A B Trust dated
October 14, 1998, an affiliate of Mr. George Hays, are parties to a Member
Agreement dated March 20, 2000, that prohibits the transfer of the membership
units owned by Mr. George Hays and The Trust, unless transferred pursuant to the
Member Agreement. The Member Agreement provides that upon the death of both G.
James Hays and Doris Helen Hays or 5 years from the date of the Member
Agreement, Mr. George Hays has the right to purchase the membership units of AZI
LLC owned by The Trust for a price determined by a specified formula and 5 years
from the date of the Member Agreement The Trust has the right to require Mr.
George Hays to purchase the membership units of AZI LLC owned by The Trust for a
price determined by a specified formula. The Member Agreement also provides that
if Mr. George Hays proposes to sell any of his membership units of AZI LLC, then
The Trust may participate in Mr. George Hays proposed sale and sell certain of
its membership units of AZI LLC on the same terms and conditions as Mr. George
Hays proposes to sell his membership units of AZI LLC.

Certain Effects of the Merger

     If the Merger is consummated, the holders of Arizona Instrument's common
stock will no longer have any interest in the Surviving Company and, therefore,
will not benefit from any future earnings or growth of the Surviving Company or
from any increases in the value of the Surviving Company and will no longer bear
the risk of any decreases in value of the Surviving Company. Instead, each
shareholder (other than Arizona Instrument and its wholly-owned subsidiaries,
AZI LLC, and dissenting shareholders) will have the right to receive upon
consummation of the Merger $5.00 in cash for each share of common stock they
hold, without interest. The benefit to the holders of common stock of the
transaction is the payment of a premium, in cash, above the market value for
such stock prior to the announcement of the transaction. This cash payment
assures that all shareholders will receive the same amount for their shares,
rather than taking the risks associated with attempting to sell their shares in
the open market. The detriment to such holders is their inability to participate
as continuing equity owners in the possible future growth of the Surviving
Company. If the Merger is consummated, the Founders will hold the entire equity
interest in the Surviving Company and will therefore be the sole beneficiaries
of any future earnings or growth of the Surviving Company and any increases in
value of the Surviving Company. However, the Founders will bear the risk of any
decreases in value of the Surviving Company and the risks associated with (1)
the significant amount of debt to be incurred by the Surviving Company in
connection with the Merger and (2) the lack of liquidity in its investment in
the Surviving Company. See "Special Factors-- Recommendation of the Special
Committee and the Board of Directors; Fairness of the Merger-- Special
Committee."

     The common stock is currently registered under the Securities Exchange Act
of 1934, as amended (the "Exchange Act"). As a result of the Merger, the common
stock will be delisted from the NASDAQ SmallCap Market, the registration of the
common stock under the Exchange Act will be terminated, Arizona Instrument will
be relieved of the obligation to comply with the proxy rules of Regulation 14A
under Section 14 of the Exchange Act, and its officers, directors and beneficial
<PAGE>
owners of more than 10% of the common stock will be relieved of the reporting
requirements and "short-swing" trading provisions under Section 16 of the
Exchange Act. Further, Arizona Instrument will no longer be subject to periodic
reporting requirements of the Exchange Act and will cease filing information
with the SEC. Accordingly, less information will be required to be made publicly
available than presently is the case.

     Rather than being governed by the certificate of incorporation and bylaws
of Arizona Instrument, the Surviving Company will be governed by the articles of
organization and operating agreement of AZI LLC.

Plans for the Surviving Company after the Merger

     Each of AZI LLC and the Founders expects that except as described in this
proxy statement, the business and operations of the Surviving Company will be
continued substantially as they are currently being conducted by Arizona
Instrument and its subsidiaries. However, the Founders expect that they may,
from time to time, evaluate and review the Surviving Company's businesses,
operations and properties and make such changes as are deemed appropriate.

     Except as described in this proxy statement, none of the Founders, AZI LLC
or Arizona Instrument has any present plans or proposals involving Arizona
Instrument or its subsidiaries which relate to or would result in an
extraordinary corporate transaction such as a merger, reorganization,
liquidation, sale or transfer of a material amount of assets, or any material
change in the present dividend policy, indebtedness or capitalization, or any
other material change in Arizona Instrument's corporate structure or business.
However, the Founders and AZI LLC will review proposals or may propose the
acquisition or disposition of assets or other changes in the Surviving Company's
business, structure, capitalization, management or distribution policy which
they consider to be in the best interests of the Surviving Company and its
members. None of Arizona Instrument, AZI LLC or the Founders have formulated any
specific plans regarding repayment of the indebtedness incurred in connection
with the Merger; however, such persons anticipate that such indebtedness will be
repaid primarily with or by means of cash from the operations of the business of
the Surviving Company, or such other means as the Surviving Company may
determine in its sole discretion and the bridge loan of up to $3,000,000 which
is part of AZI LLC's Senior Secured Credit Facility will be repaid immediately
after closing from Arizona Instrument's cash on hand.

 Conduct of the Business of Arizona Instrument If the Merger Is Not Consummated

     If the Merger is not consummated, the Board of Directors expects to seek to
retain Arizona Instrument's current management team, although there can be no
assurance it will be successful in doing so. There are no plans in such
circumstances to operate Arizona Instrument's business in a manner substantially
different than presently operated.

Accounting Treatment

     The Merger will be accounted for in accordance with the purchase method of
accounting under U.S. generally accepted accounting principles.

Financing of the Merger

     The maximum amount of funds required by AZI LLC to pay the aggregate Merger
Consideration due to shareholders and to pay cash to holders of stock options
and other rights to acquire Arizona Instrument common stock in exchange for the
cancellation of such options and other rights at the closing of the Merger
pursuant to the Agreement and Plan of Merger, assuming all shares of common
stock and stock options are converted into cash in the Merger in accordance with
the Agreement and Plan of Merger and there are no dissenting shareholders, is
expected to be approximately $6,963,381. Arizona Instrument and AZI LLC will
also require approximately $302,784 to pay other expenses and costs incurred by
Arizona Instrument and AZI LLC relating to the transactions and for other
general corporate purposes. The proceeds to pay the Merger Consideration and
related costs and expenses of the transaction will be obtained from the Senior
and Subordinated credit facilities described below and AZI LLC cash on hand. AZI
LLC does not currently have any plan or arrangement for refinancing or repaying
these borrowings, other than cash flow from operations, except that the Senior
Secured bridge loan facility in an amount up to $3,000,000 will be repaid
immediately after closing from Arizona Instrument's cash on hand.

Senior Secured Revolving Credit and Term and Bridge Loan Facility

     On March 17, 2000, AZI LLC entered into and delivered to Arizona Instrument
a commitment letter (the "Senior Debt Commitment Letter") with Imperial Bank.
Pursuant to the Senior Debt Commitment Letter, but subject to the terms and
conditions set forth therein, Imperial Bank has agreed to help finance the
Merger by lending up to approximately $6,000,000 (collectively, the "Senior Debt
Facilities") to AZI LLC, including a revolving credit facility of up $750,000
(or up to $1,250,000 after the bridge loan is extinguished), a term loan
facility of $2,250,000 and a bridge loan facility of up to $3,000,000.

     The proceeds of the Senior Debt Facilities will be used:

     *    to pay a portion of the merger consideration;

     *    to pay related transaction fees and expenses of the Merger; and

     *    for working capital and general corporate purposes.

     The Senior Debt Commitment Letter contemplates that the definitive credit
agreement governing the Senior Debt Facilities (the "Credit Agreement") will
contain terms and conditions, including, without limitation, the following:

     *    BORROWER. AZI LLC.

     *    GUARANTORS. All of AZI LLC's obligations under the Senior Debt
          Facilities will be fully and unconditionally guaranteed by George G.
          Hays.

     *    INTEREST RATE. Amounts outstanding under the revolving credit facility
          will bear interest at a rate per annum equal to the prime rate plus
          1.50%. Amounts outstanding under the term loan facility will bear
          interest at a rate per annum equal to the prime rate plus 2.50%.
          Amounts outstanding under the bridge loan facility will bear interest
          at a rate per annum equal to the prime rate.

     *    TERM. Drawings under the revolving credit facility will mature 364
          days from the Effective Time of the Merger. Borrowings under the term
          loan facility will be amortized over 60 months from the Effective Time
          of the Merger. Borrowings under the bridge loan will mature one week
          from the Effective Time of the Merger.

     *    SECURITY. The Senior Debt Facilities will be secured by:

          *    a first priority perfected pledge of and security interest in all
               of the equity interests of AZI LLC; and

          *    a first priority perfected security interest in all tangible and
               intangible assets of AZI LLC.
<PAGE>
     *    COVENANTS AND EVENTS OF DEFAULT. The Credit Agreement will contain
          affirmative and negative covenants and events of default, in each case
          which are customary for credit facilities of that size, type and
          purpose. Such affirmative and negative covenants will, among other
          matters, limit certain activities of AZI LLC and require it to satisfy
          certain ongoing financial requirements. Such events of default will
          include, among other matters, certain cross-defaults.

     *    ADDITIONAL REQUIRMENTS. The obligations of AZI LLC under the Credit
          Agreement will be subject to usual and customary conditions for credit
          facilities of the size, type and purpose contemplated by the Senior
          Debt Facilities, including, without limitation, the following:

          *    a minimum of $1,000,000 in new equity or subordinated debt, of
               which $500,000 must be equity;

          *    a subordination agreement with the subordinated debt provider
               acceptable to Imperial Bank;

          *    no dividends or distributions without prior approval of Imperial
               Bank;

          *    annual capital expenditures limitation of $400,000;

          *    George G. Hays to have and maintain majority ownership and
               control of AZI LLC; and

          *    merger agreement satisfactory to Imperial Bank.

     The Credit Agreement will also contain other terms and conditions which are
customary in transactions of the type contemplated by the Senior Debt
Facilities.

Subordinated Credit Facility

     On March 23, 2000, AZI LLC entered into and delivered to Arizona Instrument
a commitment letter (the "Subordinated Debt Commitment Letter") with Arizona
MultiBank. Pursuant to the Subordinated Debt Commitment Letter, but subject to
the conditions set forth therein, Arizona MultiBank has agreed to provide a
subordinated term loan of $500,000 (the "Subordinated Debt Facility"). The
proceeds of the Subordinated Debt Facility will be used to pay a portion of the
merger consideration.

     The Subordinated Debt Commitment Letter contemplates that the definitive
agreements governing the Subordinated Debt Facility will contain terms and
conditions which are customary in transactions of the type contemplated by the
Subordinated Debt Commitment Letter and will contain certain other terms and
conditions, including, without limitation, the following:

     *    BORROWER. AZI LLC.

     *    GUARANTORS. All of AZI LLC's obligations under the Subordinated Debt
          Facility will be fully and unconditionally guaranteed by George G.
          Hays and Jeanine C. Hays.

     *    INTEREST RATE. Amounts outstanding under the Subordinated Debt
          Facility will bear interest at a rate per annum equal to the prime
          rate plus 4.25%. Also, a yield enhancement payment in the amount of an
          accrued 2% on the principal balance will be paid annually when AZI LLC
          has positive net income before taxes.

     *    TERM. Borrowings under the term loan facility will be amortized over
          61 months from the Effective Time of the Merger.

     *    SECURITY. The Subordinated Debt Facility will be secured by a
          perfected security interest, with priority second only to Imperial
          Bank, in all tangible and intangible assets of AZI LLC.

     *    LIFE INSURANCE. AZI LLC shall maintain key person life insurance on
          George G. Hays in the amount of $500,000, naming Arizona MultiBank as
          the first beneficiary, to satisfy AZI LLC's obligations under the
          Subordinated Debt Facility.

     *    OTHER PROVISIONS. The obligations of AZI LLC under the Subordinated
          Debt Facility will be subject to usual and customary conditions for
          credit facilities of the size, type and purpose contemplated by the
          Subordinated Debt Facility, including, without limitation, the
          following:

          *    George G. Hays shall maintain no less than 51% ownership interest
               in AZI LLC;

          *    an intercreditor agreement between Arizona MultiBank and senior
               lender with commercially reasonable terms for this type of
               transaction;
<PAGE>
          *    no distributions to members of AZI LLC without written consent of
               Arizona MultiBank, except for tax liability purposes;

          *    annual capital expenditures limitation of $400,000; and

          *    compensation to George G. Hays not to exceed $200,000 per annum.

Regulatory Requirements; Third Party Consents

     Arizona Instrument does not believe that any material federal or state
regulatory approvals, filings or notices are required by Arizona Instrument in
connection with the Merger other than:

     *    such approvals, filings or notices required pursuant to federal and
          state securities laws; and

     *    the filing of the certificate of merger with the Secretary of State of
          the State of Delaware.

     Based upon AZI LLC's currently anticipated capital structure, the parties
are not required to file a Premerger Notification under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act"), because AZI LLC
does not satisfy the "size of person" jurisdictional test of the HSR Act insofar
as AZI LLC is its "ultimate parent" and does not have a regularly prepared
balance sheet or assets of $10,000,000 or more, excluding the cash that will be
used to consummate the Merger and shares of common stock and stock options to be
contributed to AZI LLC by the Founders.

     In connection with the Merger, Arizona Instrument must obtain the consent
of Imperial Bank, lender to Arizona Instrument. Arizona Instrument does not
believe any other material third party consents will be required by Arizona
Instrument in connection with the Merger.

             MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

     The following discussion is a summary of the material federal income tax
consequences expected to affect shareholders whose shares of common stock are
converted to cash in the Merger. This summary does not purport to be a complete
analysis of all potential tax effects of the Merger. For example, the summary
does not consider the effect of any applicable state, local or foreign tax laws.
In addition, the summary does not address all aspects of federal income taxation
that may affect particular shareholders in light of their particular
circumstances and is not intended for shareholders (including insurance
companies, tax-exempt organizations, financial institutions or broker-dealers,
shareholders who hold their common stock as part of a hedge, straddle or
conversion transaction, shareholders who acquired their common stock pursuant to
the exercise of an employee stock option or otherwise as compensation, and
shareholders who are not citizens or residents of the United States or that are
foreign corporations, foreign partnerships or foreign estates or trusts as to
the United States) that may be subject to special federal income tax rules not
discussed below. The following summary also does not address holders of stock
options and, except as noted, does not address tax consequences to the Founders.
The following summary assumes that shareholders have held their common stock as
"capital assets" (generally, property held for investment) under the Internal
Revenue Code.

     This summary is based on the current provisions of the Code, applicable
Treasury Regulations, judicial authority and administrative rulings and
practice. There can be no assurance that the Internal Revenue Service will not
take a contrary view. No ruling from the IRS has been or will be sought with
respect to any aspect of the transactions described herein. Future legislative,
judicial or administrative changes or interpretations could alter or modify the
statements and conclusions set forth herein, and any such changes or
interpretations could be retroactive and could affect the tax consequences to
shareholders. It cannot be predicted at this time whether any current proposed
tax legislation will be enacted or, if enacted, whether any tax law changes
contained therein would affect the tax consequences to shareholders.
<PAGE>
     EACH SHAREHOLDER IS URGED TO CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO
THE PARTICULAR TAX CONSEQUENCES TO IT OF THE TRANSACTIONS DESCRIBED HEREIN,
INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS,
AND OF CHANGES IN APPLICABLE TAX LAWS.

Treatment of Holders of Common Stock

     The conversion of common stock in the Merger will be fully taxable to
shareholders. Accordingly, a shareholder who, pursuant to the Merger, converts
such holder's common stock into cash will recognize a gain or loss equal to the
difference between (1) the amount of cash received in the Merger and (2) such
shareholder's tax basis in the common stock. Generally, a shareholder's tax
basis in his common stock will be equal to such shareholder's costs therefor. In
the case of a shareholder who is an individual, such capital gain or loss will
be taxable at a maximum capital gains rate of 20% if the holder held the common
stock for more than one year at the time of the Merger.

     For federal income tax purposes, the Surviving Company will be deemed to be
the source of a portion of the cash consideration issued in the Merger
(including the proceeds from debt used to fund the Merger that is assumed by the
Surviving Company in the Merger). Therefore, to the extent that cash received by
a shareholder is from such source, the receipt of cash in exchange for such
shareholder's common stock in the Merger will be treated as a redemption of
common stock for federal income tax purposes. If a shareholder's interest in
Arizona Instrument will terminate as a result of the Merger, taking into account
the constructive ownership rules of Section 318 of the Code, then the
shareholder will continue to receive sale or exchange treatment as described in
the preceding paragraph. If a shareholder's interest in the Surviving Company,
taking into account the constructive ownership rules of Section 318 of the Code,
is not terminated as a result of the Merger, then the shareholder will recognize
gain or loss as described above only if the deemed redemption is either "not
essentially equivalent to a dividend" or "substantially disproportionate" within
the meaning of Section 302 of the Code. Whether or not a shareholder qualifies
for sale or exchange treatment under these provisions depends on the
shareholder's individual facts and circumstances. Shareholders are urged to
consult their tax advisors with respect to the potential applicability of these
provisions.

Backup Withholding

     A shareholder whose common stock is converted to cash pursuant to the
Merger may be subject to backup withholding at the rate of 31% with respect to
the gross proceeds from the conversion of such common stock unless such
shareholder (1) is a corporation or other exempt recipient and, when required,
establishes this exemption or (2) provides its correct taxpayer identification
number, certifies that it is not currently subject to backup withholding and
otherwise complies with applicable requirements of the backup withholding rules.
A shareholder who does not provide the Surviving Company with its correct
taxpayer identification number may be subject to penalties imposed by the IRS.
Any amount withheld under these rules will be creditable against the
shareholder's federal income tax liability.

     The Surviving Company will report to shareholders and to the IRS the amount
of any reportable payments (including payments made to shareholders pursuant to
the Merger) and any amount withheld pursuant to the Merger.

     EACH SHAREHOLDER SHOULD CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO THE
PARTICULAR TAX CONSEQUENCES OF THE TRANSACTIONS DESCRIBED HEREIN, INCLUDING THE
APPLICABILITY AND EFFECT OF STATE, LOCAL AND FOREIGN TAX LAW.

Fees and Expenses

     Whether or not the Merger is consummated and except as otherwise provided
herein, all fees and expenses incurred in connection with the Merger will be
paid by the party incurring such fees and expenses, except that Arizona
Instrument will pay for all costs and expenses relating to the printing and
mailing of this proxy statement.

     In addition, under the terms of the Agreement and Plan of Merger, Arizona
Instrument will reimburse AZI LLC for certain out of pocket costs, expenses and
fees, up to a maximum of $100,000, if the Agreement and Plan of Merger is
terminated under certain circumstances. See "The Agreement and Plan of
Merger--Fees and Expenses."
<PAGE>
     Estimated fees and expenses (rounded to the nearest thousand) to be
incurred by Arizona Instrument or AZI LLC in connection with the Merger, the
financing and related transactions are as follows:


Financing Fees                                                   $100,000

                                                                 ========

- ----------

     Committee."

     To the extent not paid prior to the Effective Time by AZI LLC or Arizona
Instrument, all such fees and expenses will be paid by the Surviving Company if
the Merger is consummated. If the Merger is not consummated, each party will
bear its respective fees and expenses, except as otherwise provided in the
Agreement and Plan of Merger. See "THE AGREEMENT AND PLAN OF MERGER--Fees and
Expenses."

                   INFORMATION CONCERNING THE SPECIAL MEETING

Time, Place and Date

     This proxy statement is furnished in connection with the solicitation by
the Board of Directors of proxies from the holders of shares of common stock,
par value $.01 per share, of Arizona Instrument for use at a Special Meeting of
Shareholders (the "Special Meeting") to be held at 9:00 a.m., Mountain Standard
Time, on June 26, 2000, at Fiesta Inn, 2100 South Priest Drive, Tempe, Arizona
85282, or at any adjournment(s) or postponement(s) thereof, pursuant to the
enclosed Notice of Special Meeting of Shareholders.

Purpose of the Special Meeting

     At the Special Meeting, the shareholders of Arizona Instrument will be
asked to consider and vote upon the approval of the Agreement and Plan of Merger
and the transactions contemplated thereby. A copy of the Agreement and Plan of
Merger is attached to this proxy statement as Annex A. Pursuant to the Agreement
and Plan of Merger, each outstanding share of common stock (other than (1)
common stock held in the treasury of Arizona Instrument, (2) common stock held
by AZI LLC, or (3) common stock held by shareholders who perfect their rights
under Delaware law to dissent from the Merger and seek an appraisal of the fair
value of their shares, will be converted into the Merger Consideration.

     The Special Committee was appointed by the Board of Directors to, among
other things, review and evaluate the terms of the Merger and to make a
recommendation to the Board of Directors regarding the fairness of the Merger to
the holders of common stock. The Special Committee is composed of Dr. Emerson
(the Chairman) and Mr. Zylstra. Neither is an employee of Arizona Instrument and
none of the Special Committee members has or will have any continuing equity
interest in AZI LLC or the Surviving Company. The Special Committee concluded
that the terms and provisions of the Agreement and Plan of Merger and the Merger
are fair to and in the best interests of the holders of common stock (other than
AZI LLC and its affiliates), and unanimously recommended that the Board of
Directors approve and declare advisable the Agreement and Plan of Merger. At a
meeting held on March 31, 2000, acting on the unanimous recommendation of the
Special Committee, the Board of Directors approved the Agreement and Plan of
Merger, concluded that the terms and provisions of the
<PAGE>
Agreement and Plan of Merger are advisable and that the Agreement and Plan of
Merger and the transactions contemplated thereby, including the Merger, are fair
to, and in the best interests of, the holders of common stock (other than AZI
LLC and its affiliates), and approved a recommendation that the shareholders of
Arizona Instrument approve the Agreement and Plan of Merger and the transactions
contemplated thereby. The Special Committee and the Board of Directors, in
reaching their respective decisions, considered a number of factors, including
the opinion of Peacock Hislop, the financial advisor to the Special Committee,
that, as of the date of such opinion and based upon and subject to various
considerations, assumptions and limitations stated therein, the $5.00 per share
cash consideration to be received by the shareholders of Arizona Instrument in
the Merger was fair to the shareholders of Arizona Instrument (other than AZI
LLC and its affiliates) from a financial point of view. A copy of Peacock
Hislop's opinion is attached as Annex B to this proxy statement. See "SPECIAL
FACTORS--Recommendation of the Special Committee and Board of Directors;
Fairness of the Merger" and "SPECIAL FACTORS--Opinion of Financial Advisor to
the Special Committee."

     BASED ON THE UNANIMOUS RECOMMENDATION OF ITS SPECIAL COMMITTEE, THE BOARD
OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR APPROVAL OF THE AGREEMENT AND
PLAN OF MERGER AND THE TRANSACTIONS CONTEMPLATED THEREBY.

Record Date; Voting at the Meeting; Quorum

     Acting under authority granted to it by the Board of Directors, the Special
Committee has fixed the close of business on May 15, 2000, as the record date
(the "Record Date") for the Special Meeting. Only shareholders of record as of
the close of business on May 15, 2000, will be entitled to notice of and to vote
at the Special Meeting.

     As of the close of business on the Record Date, Arizona Instrument had
outstanding 1,371,399 shares of common stock, held of record by approximately
2,839 registered holders as of April 12, 2000. Holders of the common stock are
entitled to one vote per share. The presence in person or by proxy of the
holders of not less than one-third of the voting power of the outstanding common
stock entitled to vote at the Special Meeting constitutes a quorum. Broker
non-votes and shares as to which a shareholder abstains will be included in
determining whether there is a quorum at the Special Meeting.

Required Vote

     Under Delaware law, the Agreement and Plan of Merger must be approved by
the affirmative vote of the holders of a majority of the voting power of the
outstanding shares of common stock. The affirmative vote of approximately
685,700 shares of common stock will be necessary to satisfy this voting
requirement. Approval of the Agreement and Plan of Merger does not require the
affirmative vote of a majority of the outstanding shares of common stock held by
persons other than AZI LLC or its affiliates. The Founders, each a director of
Arizona Instrument, currently own 49,188 shares of common stock in the
aggregate, representing approximately 4% of the outstanding shares of common
stock as of the Record Date. The Founders also collectively hold options to
acquire an aggregate of 66,000 shares of common stock, which stock options will
be converted into cash in the merger. See "Special Factors--Interests of Certain
Persons in the Merger; Certain Relationships."

     Because Delaware law requires the Agreement and Plan of Merger to be
approved by the affirmative vote of the holders of a majority of the voting
power of the outstanding shares of common stock, failure to return an executed
proxy card or to vote in person at the Special Meeting or abstaining from the
vote will constitute, in effect, a vote against approval of the Agreement and
Plan of Merger and the transactions contemplated thereby for purposes of
Delaware law. Similarly, broker non-votes will have the same effect as a vote
against approval of the Agreement and Plan of Merger and the transactions
contemplated thereby.

Voting and Revocation of Proxies

     The enclosed proxy card is solicited on behalf of the Board of Directors.
The giving of a proxy does not preclude the right to vote in person should any
shareholder giving the proxy so desire. Shareholders have an unconditional right
to revoke their proxy at any time prior to its exercise, either by filing with
Arizona Instrument's Secretary at Arizona Instrument's principal executive
offices a written revocation or a duly executed proxy bearing a later date or by
voting in person at the Special Meeting. Attendance at the Special Meeting
without casting a ballot will not, by itself, constitute revocation of a proxy.
Any written notice revoking a proxy should be sent to the transfer agent,
ChaseMellon Shareholder Services, 85 Challenger Road, Ridgefield Park, New
Jersey 07660.
<PAGE>
Action to Be Taken at the Special Meeting

     All shares of common stock represented at the Special Meeting by properly
executed proxies received prior to or at the Special Meeting, unless previously
revoked, will be voted at the Special Meeting in accordance with the
instructions on the proxies. Unless contrary instructions are indicated, proxies
will be voted "FOR" the approval of the Agreement and Plan of Merger and the
transactions contemplated thereby. As explained below in the section entitled
"Dissenters' Rights of Appraisal," a vote in favor of the Agreement and Plan of
Merger means that the shareholder owning those shares will not have the right to
dissent and seek appraisal of the fair value of such shareholder's shares.
Arizona Instrument does not know of any matters, other than as described in the
Notice of Special Meeting of Shareholders, which are to come before the Special
Meeting. If any other matters are properly presented at the Special Meeting for
action, including, among other things, consideration of a motion to adjourn such
meeting to another time and/or place (including, without limitation, for the
purpose of soliciting additional proxies or allowing additional time for the
satisfaction of conditions to the Merger), the persons named in the enclosed
proxy card and acting thereunder generally will have discretion to vote on such
matters in accordance with their best judgment. Notwithstanding the foregoing,
the persons named in the enclosed proxy card will not use their discretionary
authority to use proxies voting against the Merger to vote in favor of
adjournment or postponement of the Special Meeting. The Merger is also subject
to a number of additional conditions. See "THE AGREEMENT AND PLAN OF
MERGER--Conditions."

Proxy Solicitation

     The cost of preparing, assembling and mailing this proxy statement, the
Notice of Special Meeting of Shareholders and the enclosed proxy card will be
borne by Arizona Instrument. Arizona Instrument is requesting that banks,
brokers and other custodians, nominees and fiduciaries forward copies of the
proxy material to their principals and request authority for the execution of
proxies. Arizona Instrument may reimburse such persons for their expenses in so
doing. In addition to the solicitation of proxies by mail, the directors,
officers and employees of Arizona Instrument and its subsidiaries may, without
receiving any additional compensation, solicit proxies by telephone, telefax,
telegram or in person.

     No person is authorized to give any information or make any representation
not contained in this proxy statement, and if given or made, such information or
representation should not be relied upon as having been authorized.

     COMPANY SHAREHOLDERS SHOULD NOT SEND ANY CERTIFICATES REPRESENTING SHARES
OF COMMON STOCK WITH THEIR PROXY CARD. IF THE MERGER IS CONSUMMATED, THE
PROCEDURE FOR THE EXCHANGE OF CERTIFICATES REPRESENTING SHARES OF COMMON STOCK
WILL BE AS SET FORTH IN THIS PROXY STATEMENT. SEE "THE AGREEMENT AND PLAN OF
MERGER--THE EXCHANGE FUND; PAYMENT FOR SHARES OF COMMON STOCK" AND "THE
AGREEMENT AND PLAN OF MERGER--TRANSFERS OF COMMON STOCK."

                        THE AGREEMENT AND PLAN OF MERGER

     The following is a summary of the material provisions of the Agreement and
Plan of Merger, a copy of which is attached as Annex A to this proxy statement.
Such summary is qualified in its entirety by reference to the full text of the
Agreement and Plan of Merger.

The Merger; Merger Consideration

     The Agreement and Plan of Merger provides that the Merger will become
effective upon the filing of the articles of merger with the Corporation
Commission of the State of Arizona or at such other time as the parties may
agree and specify in the articles of merger (the "Effective Time"). If the
Merger is approved at the Special Meeting by the holders of a majority of all
outstanding shares of common stock, and the other conditions to the Merger are
satisfied or waived, it is currently anticipated that the Merger will become
effective as soon as practicable after the Special Meeting; however, there can
<PAGE>
be no assurance as to the timing of the consummation of the Merger or that the
Merger will be consummated.

     At the Effective Time, Arizona Instrument will be merged with and into AZI
LLC, the separate corporate existence of Arizona Instrument will cease and AZI
LLC will continue as the Surviving Company. In the Merger and at the Effective
Time:

     *    each share of common stock issued and outstanding immediately prior to
          the Effective Time (other than common stock held by Arizona Instrument
          or its wholly-owned subsidiaries, AZI LLC or Dissenting Shareholders)
          will, by virtue of the Merger and without any action on the part of
          the holder thereof, be converted into and become the right to receive
          cash in the amount of $5.00;

     *    each share of common stock issued and outstanding immediately prior to
          the Effective Time that is owned by Arizona Instrument or its
          wholly-owned subsidiaries or AZI LLC will automatically be canceled,
          retired and cease to exist and no payment will be made with respect
          thereto;

     *    each membership unit of AZI LLC outstanding immediately prior to the
          Effective Time will remain outstanding and will not be modified and
          will constitute the only outstanding membership units of the Surviving
          Company;

     *    Dissenting Shareholders who do not vote to approve the Agreement and
          Plan of Merger and who otherwise strictly comply with the provisions
          of the Delaware General Corporation Law regarding statutory appraisal
          rights have the right to seek a determination of the fair value of
          their shares of common stock and payment in cash therefor in lieu of
          the Merger Consideration. See "DISSENTERS' RIGHTS OF APPRAISAL;" and

     *    each certificate representing shares of common stock that has been
          converted to cash under the terms of the Agreement and Plan of Merger
          will, after the Effective Time, evidence only the right to receive,
          upon the surrender of such certificate, cash in the amount of $5.00
          per share.

Treatment of Certain Shares Held by the Founders

     Shares of Arizona Instrument common stock held by each of the Founders will
be treated the same as all other shares of common stock in the Merger.

     Options to acquire shares of common stock of Arizona Instrument held by the
Founders will be treated the same in the Merger as options held by other
employees and directors of Arizona Instrument.

The Exchange Fund; Payment for Shares of Common Stock

     On or before the closing date of the Merger, AZI LLC will enter into an
agreement with a bank, trust company or other exchange agent selected by AZI LLC
and reasonably satisfactory to Arizona Instrument (the "Exchange Agent"). As of
the Effective Time, AZI LLC or the Surviving Company will deposit or cause to be
deposited with the Exchange Agent, cash in the amount equal to the aggregate
Merger Consideration (such amount being hereinafter referred to as the "Exchange
Fund") for the benefit of holders of shares of the common stock (other than
common stock held by dissenting shareholders and shares to be canceled without
consideration pursuant to the Agreement and Plan of Merger).

     Within five business days following the Effective Time, the Exchange Agent
will mail to each record holder of a certificate or certificates, which
immediately prior to the Effective Time represented outstanding shares of common
stock that have been converted pursuant to the Agreement and Plan of Merger into
the right to receive Merger Consideration, a letter of transmittal and
instructions for use in surrendering certificates in exchange for the Merger
Consideration. No shareholder should surrender any certificates until the
shareholder receives the letter of transmittal and other materials for such
surrender. Upon surrender of a certificate for cancellation to the Exchange
Agent, together with a letter of transmittal, duly executed, and such other
customary documents as may be required pursuant to the instructions, the holder
of such certificate will be entitled to receive, in exchange therefore, the
<PAGE>
Merger Consideration into which the number of shares of common stock previously
represented by such certificate(s) shall have been converted pursuant to the
Agreement and Plan of Merger, without any interest thereon, and the certificates
so surrendered will be canceled.

     If payment of the Merger Consideration is to be made to a person other than
the person in whose name the certificate surrendered is registered, it will be a
condition of payment that the certificate so surrendered will be properly
endorsed (together with signature guarantees on such certificate) or otherwise
be in proper form for transfer and that the person requesting such payment pay
to the Exchange Agent any transfer or other taxes required by reason of the
payment of the Merger Consideration to a person other than the registered holder
thereof or establish to the satisfaction of the Exchange Agent that such tax has
been paid or is not applicable.

     SHAREHOLDERS SHOULD NOT SEND THEIR CERTIFICATES NOW AND SHOULD SEND THEM
ONLY PURSUANT TO INSTRUCTIONS SET FORTH IN THE LETTER OF TRANSMITTAL TO BE
MAILED TO SHAREHOLDERS PROMPTLY AFTER THE EFFECTIVE TIME. IN ALL CASES, THE
MERGER CONSIDERATION WILL BE PROVIDED ONLY IN ACCORDANCE WITH THE PROCEDURES SET
FORTH IN THIS PROXY STATEMENT AND SUCH LETTER OF TRANSMITTAL.

     Eighteen months after the Effective Time, the Exchange Agent will deliver
to the Surviving Company or otherwise at the direction of the Surviving Company
any portion of the Exchange Fund that remains undistributed to or unclaimed by
the holders of certificates (including the proceeds of any investments thereof),
and any holders of certificates who have not theretofore complied with the
above-described procedures to receive payment of the Merger Consideration may
look only to the Surviving Company for payment of the Merger Consideration to
which they are entitled.

Transfers of Common Stock and Rights Under Stock Purchase Plan

     After the Effective Time, the stock transfer books of Arizona Instrument
will be closed, and there will be no further transfers of Certificates on the
records of Arizona Instrument or its transfer agent. If, after the Effective
Time, certificates are presented to the Exchange Agent or the Surviving Company,
they will be canceled and exchanged for the Merger Consideration as provided
above and pursuant to the terms of the Agreement and Plan of Merger (subject to
applicable law in the case of dissenting shareholders).

Treatment of Stock Options

     It is currently anticipated that at the Effective Time, each unexercised
option to acquire common stock will be canceled. See "Interests of Certain
Persons in the Merger; Certain Relationships." Each holder of an exercisable
stock option(including options which vest as a result of the transactions
contemplated by the Agreement and Plan of Merger) who is an employee, officer or
director of Arizona Instrument at the Effective Time will receive, in
consideration of such cancellation, as soon as practicable after the Effective
Time, a cash payment equal to the product of (1) the excess, if any, of the
Merger Consideration over the per share exercise price of such stock option,
multiplied by (2) the aggregate number of shares of common stock then subject to
such stock option, subject to any required withholding of taxes (the "Stock
Option Consideration"). At the Effective Time, all such stock options, will be
converted into, and will thereafter only represent the right to receive, the
Stock Option Consideration. Exercisable stock options held by persons other than
employees, officers and directors of Arizona Instrument which are not exercised
prior to the Effective Time, will be canceled and no payment will be made in
respect thereof.

     It is currently anticipated that the participants in the Arizona Instrument
1985 Stock Purchase Plan will be permitted to continue payroll withholding
pursuant to their current instructions in accordance with the provisions of the
Plan, except that the last business day before the Effective Time will be deemed
the final date of the deductive period for purposes of the Plan. At the
Effective Time, AZI LLC will pay to each participant the excess, if any, of the
Merger Consideration over the purchase price as established by the Plan, and all
withheld funds will be returned to the participants.

the Merger are subject to the following conditions, among others:

          vote of the holders of a majority of all outstanding shares of common

          true and correct, individually or in the aggregate, would not have a
          material adverse effect on Arizona Instrument (without giving effect
          to qualifications as to materiality contained within such
          representations and warranties) or would not prevent completion of the
          Merger by September 30, 2000, or under certain circumstances by

          true and correct as of the Effective Time as though made on and as of
          the Effective Time, except where, among other things, the failure to
          be true and correct, individually or in the aggregate, would not have
          a material adverse effect on AZI LLC (without giving effect to
          qualifications as to materiality contained within such representations
          and warranties) or would not prevent completion of the Merger by the
          Outside Date; and

     Arizona Instrument has agreed to operate, and cause each of its
subsidiaries to operate, their respective businesses in the ordinary and usual
course prior to the Effective Time. In this regard, Arizona Instrument has

     *    make material capital expenditures or commitments.

     AZI LLC has agreed that it will not, without the consent of Arizona
Instrument (which consent may not be unreasonably withheld or delayed), take
certain types of actions or engage in certain types of transactions.
Specifically, AZI LLC agreed that prior to the Effective Time, it will not,

     *    amend its organizational documents in any way that would delay the
          timely consummation of the Merger or prevent the consummation of the
          Merger by the Outside Date;

     *    change its capital structure in a manner that would materially delay
          the timely consummation of the Merger or prevent the consummation of
          the Merger by the Outside Date; or

     *    take any action that could reasonably be expected to result in any of
          the conditions to the Merger not being satisfied.
<PAGE>
     In addition, AZI LLC and the Founders agreed to use their best efforts to
consummate financing on terms consistent with the commitment letters; to keep
the commitment letters in effect until the Effective Time; to maintain certain
employee benefits for one year following the Effective Time; to maintain
provisions in the organizational documents of the Surviving Company regarding
the indemnification of directors and officers following the Effective Time; and

     AZI LLC and Arizona Instrument have made further agreements regarding,
among other things:

     *    advising each other of representations or warranties contained in the
          Agreement and Plan of Merger becoming untrue, of their respective
          failure to comply with or satisfy covenants, conditions or agreements
          contained in the Agreement and Plan of Merger and of any change, event
          or circumstance that could reasonably be expected to have a material
          adverse effect on such party or on its ability to consummate the
          proposed Merger by the Outside Date; and

     *    cooperating in the preparation of required governmental filings, in
          obtaining required permits and regulatory approvals and in the release
          of public announcements, and granting access to information and
          maintaining confidentiality.

Acquisition Proposals

     The Agreement and Plan of Merger provides that, at any time prior to the
Effective Time (unless AZI LLC consents in writing), Arizona Instrument and the
Special Committee will not, and Arizona Instrument will use its reasonable best
efforts to cause its and the Special Committee's representatives not to, either
directly or indirectly, initiate, or solicit the making, submission or
announcement of any Acquisition Proposal. "Acquisition Proposal" means any
offer, indication of interest or proposal relating to a transaction involving
the acquisition of stock or assets of Arizona Instrument which would, upon
consummation, materially and adversely affect the ability of the parties to
consummate the transactions contemplated by the Agreement and Plan of Merger.
"Acquisition Proposal" does not include any offer, indication of interest or
proposal made by AZI LLC or any of the Founders or any of them jointly with any
other person.

     In addition, Arizona Instrument and the Special Committee will not, and
Arizona Instrument will use its reasonable best efforts to cause its and the
Special Committee's representatives not to, either directly or indirectly,
engage in discussions with, furnish or provide any non-public information to, or
afford access to the properties, books, records and representatives of Arizona
Instrument to, any person with respect to any Acquisition Proposal unless the
Special Committee determines in good faith that the Acquisition Proposal is
reasonably likely to lead to a Superior Proposal (as defined below), such person
has entered into an appropriate confidentiality agreement and Arizona Instrument
has notified AZI LLC of the initial receipt of such proposal and the terms of
the proposal. Arizona Instrument is not required to disclose to AZI LLC the
identity of any person making an Acquisition Proposal.

     In addition, Arizona Instrument, the Board of Directors or the Special
Committee may withdraw or modify its recommendation of, or refrain from
recommending, the Merger and the Agreement and Plan of Merger, approve any
Acquisition Proposal, declare any Acquisition Proposal advisable, recommend an
Acquisition to Arizona Instrument's shareholders or enter into a definitive
acquisition agreement in respect of an Acquisition Proposal if, prior to taking
such actions the Special Committee determines in good faith that such
Acquisition Proposal is a Superior Proposal. A "Superior Proposal" is an
Acquisition Proposal which:

     *    is at least as likely as the Merger to be consummated;

     *    is accompanied by evidence of cash on hand or readily available under
          existing lines of credit or written commitments for financing
          sufficient to fund its consummation; and

     *    would, if consummated, result in a transaction more favorable to
          Arizona Instrument's shareholders from a financial point of view than
          the transactions contemplated by the Agreement and Plan of Merger.

     Finally, Arizona Instrument, its Board of Directors or the Special
Committee may take such actions as required by the rules promulgated under the
Exchange Act with regard to tender offers received by Arizona Instrument.

Termination

     The Agreement and Plan of Merger may be terminated at any time prior to the
Effective Time, whether before or after the approval of the proposed Merger by
the shareholders of Arizona Instrument, by the mutual written consent of Arizona
Instrument and AZI LLC, or by either or AZI LLC if:

     *    any permanent injunction, judgment, order, decree, ruling or other
          action of any governmental entity prohibiting the consummation of the
          Merger has become final and nonappealable;

     *    the Merger has not been consummated by the Outside Date (provided that
          such termination will not be available to any party whose material
          breach of any representation, warranty, covenant or agreement under
          the Agreement and Plan of Merger has been the cause of or resulted in
          the failure of the Merger to occur on or before such date);

     *    the required Arizona Instrument shareholder approval is not obtained
          (provided that, this right to terminate will not be available to AZI
          LLC if AZI LLC and the Founders shall not have voted in favor of the
          approval of the Agreement and Plan of Merger and the Merger); or
<PAGE>
     *    Arizona Instrument's Board of Directors, based upon the recommendation
          of the Special Committee, determines to accept a Superior Proposal.

     Arizona Instrument may also terminate the Agreement and Plan of Merger at
any time prior to the Effective Time, whether before or after the approval of
the proposed Merger by the shareholders, upon a breach by AZI LLC of any
representation, warranty, covenant or obligation set forth in the Agreement and
Plan of Merger which would have a material adverse effect on AZI LLC (without
giving effect to qualifications as to materiality contained within such
representations and warranties), which breach is not or cannot be materially
cured by the Outside Date.

     AZI LLC may also terminate the Agreement and Plan of Merger at any time
prior to the Effective Time, whether before or after the approval of the
proposed Merger by the shareholders of Arizona Instrument:

     *    if the Arizona Instrument Board of Directors, based upon the
          recommendation of the Special Committee:

          *    withdraws or adversely modifies its recommendation of the
               Agreement and Plan of Merger;

          *    recommends to the shareholders of Arizona Instrument that they
               approve an Acquisition Proposal other than the proposed Merger;

          *    fails to include the Board of Directors's recommendation in favor
               of the Agreement and Plan of Merger or the fairness opinion of
               Peacock, Hislop, Staley & Given, Inc. in this proxy statement; or

          *    fails to mail this proxy statement within the time periods set
               forth in the Agreement and Plan of Merger or has postponed or,
               without obtaining the required shareholder vote, adjourned the
               shareholder meeting, in each case, when an Acquisition Proposal
               from a person other than AZI LLC was publicly pending or known to
               the Special Committee;

     *    if an Acquisition Proposal made as a tender offer or exchange offer is
          commenced and the Arizona Instrument Board of Directors shall not have
          timely recommended rejection of such offer;

     *    upon a breach by Arizona Instrument of any representation, warranty,
          covenant or obligation set forth in the Agreement and Plan of Merger,
          which would result in the funding of the debt and equity financings
<PAGE>
          being provided by Imperial Bank and Arizona MultiBank and the Founders
          not occurring or the proceeds thereof not being immediately available
          at the Effective Time or which would have a material adverse effect on
          Arizona Instrument (without giving effect to qualifications as to
          materiality contained within such representations and warranties),
          which breach is not or cannot be materially cured by the Outside Date;
          or

     *    if, despite the exercise of best efforts by AZI LLC and the Founders,
          the funding of the financing for the completion of the Merger does not
          occur by the Outside Date by reason of any failure of any condition to
          the definitive financing documents or upon the exercise by any party
          to the definitive financing documents (other than AZI LLC or any of
          the Founders) of any right to terminate the definitive financing
          documents.

Fees and Expenses

     Whether or not the Merger is consummated and except as otherwise provided
in the Agreement and Plan of Merger, all fees and expenses incurred in
connection with the Merger will be paid by the party incurring such fees and
expenses, except that (1) Arizona Instrument will pay for all costs and expenses
relating to the printing, filing and mailing of this proxy statement and (2) if
the Merger is consummated, the Surviving Company will pay any real property
transfer tax imposed on the holders of shares of capital stock of Arizona
Instrument resulting from the Merger.

     Under the terms of the Agreement and Plan of Merger, Arizona Instrument
will reimburse AZI LLC for its out-of-pocket expenses incurred after January 31,
2000 in connection with the Merger, up to maximum of $100,000 (the "Costs and
Expenses") within two business days after the termination of the Agreement and
Plan of Merger if:

     *    the Agreement and Plan of Merger is terminated by Arizona Instrument
          or AZI LLC because the required shareholder approval is not obtained
          and on or within the five business days prior to the shareholders
          meeting at which such approval was sought, a publicly announced
          Acquisition Proposal from a person other than AZI LLC was pending;

     *    the Agreement and Plan of Merger is terminated by Arizona Instrument
          or AZI LLC because the Arizona Instrument Board of Directors, based on
          the recommendation of the Special Committee, resolved to accept a
          Superior Proposal;

     *    the Agreement and Plan of Merger is terminated by AZI LLC because the
          Arizona Instrument Board of Directors, based on the recommendation of
          the Special Committee:

     *    withdraws or adversely modifies its recommendation of the Agreement
          and Plan of Merger;

     *    recommends to the shareholders of Arizona Instruments that they
          approve another Acquisition Proposal;

     *    fails to include a recommendation in favor of the Agreement and Plan
          of Merger or the fairness opinion of Peacock, Hislop, Staley & Givens,
          Inc. in this proxy statement while an Acquisition Proposal from a
          person other than AZI LLC was publicly pending or known to the Special
          Committee; or

     *    fails to mail a proxy statement within the time periods set forth in
          the Agreement and Plan of Merger or has postponed or, without
          obtaining the required shareholder vote, adjourned the shareholder
          meeting, in each case, when an Acquisition Proposal from a person
          other than AZI LLC is publicly pending or known to the Special
          Committee;

     *    the Agreement and Plan of Merger is terminated by AZI LLC because the
          Arizona Instrument Board of Directors fails to timely recommend
          rejection of an Acquisition Proposal made as a tender offer or
          exchange offer; or
<PAGE>
     *    Arizona Instrument willfully and materially breaches its covenants,
          obligations, representations or warranties with regard to Acquisition
          Proposals set forth in the Agreement and Plan of Merger.

Amendment/Waiver

     Before or after approval of the Agreement and Plan of Merger by the
shareholders, the Agreement and Plan of Merger may be amended by the written
agreement of the parties thereto at any time prior to the Effective Time if such
amendment is approved on behalf of Arizona Instrument by the Special Committee,
and on behalf of AZI LLC by its managers; provided that, after any such
shareholder approval has been obtained, no amendment may be made that under
applicable law or Nasdaq rules requires the approval of the shareholders Arizona

dissent from the Merger and elect to have the fair value of such shareholder's
shares of common stock (exclusive of any element of value arising from the
accomplishment or expectation of the Merger) judicially determined and paid to
such shareholder in cash, together with a fair rate of interest, if any,
provided that such shareholder complies with the provisions of Section 262.

     The following discussion is not a complete statement of the law pertaining
to appraisal rights under the DGCL, and is qualified in its entirety by the full
text of Section 262, which is provided in its entirety as Annex C to this proxy
statement. All references in Section 262 and in this summary to a "shareholder"
are to the record holder of the shares of common stock as to which appraisal
rights are asserted. A person having a beneficial interest in shares of common
stock held of record in the name of another person, such as a broker or nominee,
must act promptly to cause the record holder to follow properly the steps
summarized below and in timely manner to perfect appraisal rights.

     Under Section 262, where a proposed merger is to be submitted for approval
at a meeting of shareholders, as in the case of the Special Meeting, the
corporation, not less than 20 days prior to the meeting, must notify each of its
shareholders entitled to appraisal rights that such appraisal rights are
available and include in such notice a copy of Section 262. This proxy statement
will constitute such notice to the holders of common stock and the applicable
statutory provisions of the DGCL are attached to this proxy statement as Annex
C. Any shareholder who wishes to exercise such appraisal rights or who wishes to
preserve the right to do so should review carefully the following discussion and
Annex C to this proxy statement. FAILURE TO COMPLY WITH THE PROCEDURES SPECIFIED
IN SECTION 262 TIMELY AND PROPERLY WILL RESULT IN THE LOSS OF APPRAISAL RIGHTS.
Moreover, because of the complexity of the procedures for exercising the right
to seek appraisal of the common stock, Arizona Instrument believes that
shareholders who consider exercising such rights should seek the advice of
counsel.

     Any holder of common stock wishing to exercise the right to dissent from
the Merger and demand appraisal under Section 262 of the DGCL must satisfy each
of the following conditions:

     *    deliver to Arizona Instrument a written demand for appraisal of such
          shareholder's shares before the vote on the Agreement and Plan of
          Merger at the Special Meeting, which demand will be sufficient if it
          reasonably informs Arizona Instrument of the identity of the
          shareholder and that the shareholder intends thereby to demand the
          appraisal of such holder's shares;

     *    not vote the holder's shares of common stock in favor of the Agreement
          and Plan of Merger; a proxy which does not contain voting instructions
          will, unless revoked, be voted in favor of the Agreement and Plan of
<PAGE>
          Merger. Therefore, a shareholder who votes by proxy and who wishes to
          exercise appraisal rights must vote against the Agreement and Plan of
          Merger or abstain from voting on the Agreement and Plan of Merger; and

     *    continuously hold such shares from the date of making the demand
          through the Effective Time. A shareholder who is the record holder of
          shares of common stock on the date the written demand for appraisal is
          made but who thereafter transfers such shares prior to the Effective
          Time will lose any right to appraisal in respect of such shares.

     Neither voting (in person or by proxy) against, abstaining from voting on,
or failing to vote on the proposal to approve the Agreement and Plan of Merger
will constitute a written demand for appraisal within the meaning of Section
262. The written demand for appraisal must be in addition to and separate from
any such proxy or vote.

     Only a holder of record of shares of common stock issued and outstanding
immediately prior to the Effective Time is entitled to assert appraisal rights
for the shares of common stock registered in that holder's name. A demand for
appraisal should be executed by or on behalf of the shareholder of record, fully
and correctly, as such shareholder's name appears on such stock certificates,
should specify the shareholder's name and mailing address, the number of shares
of common stock owned and that such shareholder intends thereby to demand
appraisal of such shareholder's common stock. If the shares are owned of record
in a fiduciary capacity, such as by a trustee, guardian or custodian, execution
of the demand should be made in that capacity. If the shares are owned of record
by more than one person as in a joint tenancy or tenancy in common, the demand
should be executed by or on behalf of all owners. An authorized agent, including
one or more joint owners, may execute a demand for appraisal on behalf of a
shareholder; however, the agent must identify the record owner or owners and
expressly disclose the fact that, in executing the demand, the agent is acting
as agent for such owner or owners. A record holder such as a broker who holds
shares as nominee for several beneficial owners may exercise appraisal rights
with respect to the shares held for one or more beneficial owners while not
exercising such rights with respect to the shares held for one or more other
beneficial owners; in such case, the written demand should set forth the number
of shares as to which appraisal is sought, and where no number of shares is
expressly mentioned the demand will be presumed to cover all shares held in the
name of the record owner. Shareholders who hold their shares in brokerage
accounts or other nominee forms and who wish to exercise appraisal rights are
urged to consult with their brokers to determine and appropriate procedures for
the making of a demand for appraisal by such nominee.

     A shareholder who elects to exercise appraisal rights pursuant to Section
262 should mail or deliver a written demand to: Arizona Instrument Corporation,
1912 West 4th Street, Tempe, Arizona 85281, Linda J. Shepherd, Secretary.

     Within ten days after the Effective Time, the Surviving Company must send a
notice as to the effectiveness of the Merger to each former shareholder of
Arizona Instrument who has made a written demand for appraisal in accordance
with Section 262 and who has not voted in favor of the Agreement and Plan of
Merger. Within 120 days after the Effective Time, but not thereafter, either the
Surviving Company or any dissenting shareholder who has complied with the
requirements of Section 262 may file a petition in the Delaware Chancery Court
demanding a determination of the value of the shares of common stock held by all
dissenting shareholders. Arizona Instrument is under no obligation to and has no
present intent to file a petition for appraisal, and shareholders seeking to
exercise appraisal rights should not assume that the Surviving Company will file
such a petition or that the Surviving Company will initiate any negotiations
with respect to the fair value of such shares. Accordingly, shareholders who
desire to have their shares appraised should initiate any petitions necessary
for the perfection of their appraisal rights within the time periods and in the
manner prescribed in Section 262. Inasmuch as Arizona Instrument has no
obligation to file such a petition, the failure of a shareholder to do so within
the period specified could nullify such shareholder's previous written demand
for appraisal. In any event, at any time within 60 days after the Effective Time
(or at any time thereafter with the written consent of Arizona Instrument), any
shareholder who has demanded appraisal has the right to withdraw the demand and
to accept payment of the Merger Consideration.

     Within 120 days after the Effective Time, any shareholder who has complied
with the provisions of Section 262 to that point in time will be entitled to
receive from the Surviving Company, upon written request, a statement setting
forth the aggregate number of shares not voted in favor of the Agreement and
Plan of Merger and with respect to which demands for appraisal have been
received and the aggregate number of holders of such shares. The Surviving
Company must mail such statement to the shareholder within 10 days of receipt of
such request or within 10 days after expiration of the period for delivery of
demands for appraisals under Section 262, whichever is later.
<PAGE>
     A shareholder timely filing a petition for appraisal with the Court of
Chancery must deliver a copy to the Surviving Company, which will then be
obligated within 20 days to provide the Delaware Court of Chancery with a duly
verified list containing the names and addresses of all shareholders who have
demanded appraisal of their shares. After notice to such shareholders, the
Delaware Court of Chancery is empowered to conduct a hearing on the petition to
determine which shareholders are entitled to appraisal rights. The Delaware
Court of Chancery may require shareholders who have demanded an appraisal for
their shares and who hold stock represented by certificates to submit their
certificates to the Register in Chancery for notation thereon of the pendency of
the appraisal proceedings, and if any shareholder fails to comply with the
requirement, the Delaware Court of Chancery may dismiss the proceedings as to
that shareholder.

     After determining the shareholders entitled to an appraisal, the Delaware
Court of Chancery will appraise the "fair value" of their shares, exclusive of
any element of value arising from the accomplishment or expectation of the
Merger, together with a fair rate of interest, if any, to be paid upon the
amount determined to be the fair value. The costs of the action may be
determined by the Delaware Chancery Court and taxed upon the parties as the
Delaware Chancery Court deems equitable. Upon application of a dissenting
shareholder, the Delaware Chancery Court may also order that all or a portion of
the expenses incurred by any shareholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorneys' fees and the
fees and expenses of experts, be charged pro rata against the value of all of
the shares entitled to appraisal. SHAREHOLDERS CONSIDERING SEEKING APPRAISAL
SHOULD BE AWARE THAT THE FAIR VALUE OF THEIR SHARES AS DETERMINED UNDER SECTION
262 COULD BE MORE THAN, THE SAME AS OR LESS THAN THE MERGER CONSIDERATION THEY
WOULD RECEIVE PURSUANT TO THE AGREEMENT AND PLAN OF MERGER IF THEY DID NOT SEEK
APPRAISAL OF THEIR SHARES. SHAREHOLDERS SHOULD ALSO BE AWARE THAT INVESTMENT
BANKING OPINIONS ARE NOT OPINIONS AS TO FAIR VALUE UNDER SECTION 262.

     In determining fair value and, if applicable, a fair rate of interest, the
Delaware Chancery Court is to take into account all relevant factors. In
Weinberger v. UOP, Inc., the Delaware Supreme Court discussed the factors that
could be considered in determining fair value in an appraisal proceeding,
stating that "proof of value by any techniques or methods that are generally
considered acceptable in the financial community and otherwise admissible in
court" should be considered, and that "fair price obviously requires
consideration of all relevant factors involving the value of a company." The
Delaware Supreme Court stated that, in making this determination of fair value,
the court must consider market value, asset value, dividends, earnings
prospects, the nature of the enterprise and any other facts that could be
ascertained as of the date of the merger that throw any light on future
prospects of the merged corporation. In Weinberger, the Delaware Supreme Court
stated that "elements of future value, including the nature of the enterprise,
that are known or susceptible of proof as of the date of the merger and not the
product of speculation, may be considered." Section 262 provides that fair value
is to be "exclusive of any element of value arising from the accomplishment or
expectation of the merger."

     Any shareholder who has duly demanded an appraisal in compliance with
Section 262 will not, after the Effective Time, be entitled to vote the shares
subject to such demand for any purpose or be entitled to the payment of
dividends or other distributions on those shares (except dividends or other
distributions payable to holders of record of shares as of a record date prior
to the Effective Time).

     Any shareholder may withdraw its demand for appraisal and accept the Merger
Consideration by delivering to the Surviving Company a written withdrawal of
such shareholder's demands for appraisal, except that (1) any such attempt to
withdraw made more than 60 days after the Effective Time will require written
approval of the Surviving Company and (2) no appraisal proceeding in the
Delaware Chancery Court shall be dismissed as to any shareholder without the
approval of the Delaware Chancery Court, and such approval may be conditioned
upon such terms as the Delaware Chancery Court deems just. If the Surviving
Company does not approve a shareholder's request to withdraw a demand for
appraisal when such approval is required, or if the Delaware Chancery Court does
not approve the dismissal of an appraisal proceeding, the shareholder would be
entitled to receive only the appraised value determined in any such appraisal
proceeding, which value could be lower than the value of the Merger
Consideration.
<PAGE>
     FAILURE TO COMPLY STRICTLY WITH ALL OF THE PROCEDURES SET FORTH IN SECTION
262 OF THE DGCL WILL RESULT IN THE LOSS OF A SHAREHOLDER'S STATUTORY APPRAISAL
RIGHTS. CONSEQUENTLY, ANY SHAREHOLDER WISHING TO EXERCISE APPRAISAL RIGHTS IS
URGED TO CONSULT LEGAL COUNSEL BEFORE ATTEMPTING TO EXERCISE SUCH RIGHTS.

     This proxy statement contains or incorporates by reference certain
forward-looking statements and information relating to Arizona Instrument that
are based on the beliefs of management as well as assumptions made by and
information currently available to Arizona Instrument. Forward-looking
statements include statements concerning plans, objectives, goals, strategies,

words "anticipate," "believe," "estimate," "expect," "plan," "intend,"
"project," "predict," "may," and "should" and similar expressions, are intended
to identify forward-looking statements. Such statements reflect the current view
of Arizona Instrument with respect to future events, including the completion of
the proposed Merger, and are subject to numerous risks, uncertainties and
assumptions. Many factors could cause the actual results, performance or
achievements of Arizona Instrument to be materially different from any future
results, performance or achievements that may be expressed or implied by such
forward-looking statements, including, among others:

     *    litigation and claims in respect of Arizona Instrument's former
          Encompass product line and other product liability matters;

     *    delays in receiving required regulatory and other approvals;

     *    any inability of AZI LLC to obtain funding necessary to consummate the
          proposed Merger;
<PAGE>
     *    the failure of shareholders to approve the Agreement and Plan of
          Merger;

     *    inability to attract and retain qualified personnel;

     *    deterioration of general economic or market conditions;

     *    changes in business strategy;

     *    lack of availability of financing on acceptable terms to fund future
          growth;

     *    competitive conditions in Arizona Instrument's markets; and

     *    various other factors, both referenced and not referenced in this
          proxy statement.

     Should one or more of these risks or uncertainties materialize, or should
underlying assumptions prove incorrect, actual results may vary materially from
those described herein as anticipated, believed, estimated, expected, planned or
intended. Arizona Instrument does not intend, or assume any obligation, to
update these forward-looking statements to reflect actual results, changes in
assumptions or changes in the factors affecting such forward-looking statements.

2000,  is  by  and  among  AZI  LLC,  an  Arizona  limited   liability   company
("ACQUIRER"),  George G. Hays and Harold D.  Schwartz  (the  "PRINCIPALS"),  and
Arizona Instrument Corp., a Delaware corporation (the "COMPANY").

                                  WITNESSETH:

     A. The members of Acquirer  and the Board of  Directors of the Company have
approved and adopted this Agreement and the  transactions  contemplated  hereby,
including  the  Merger,  subject to the terms and  conditions  set forth in this
Agreement.

     B. The Board of Directors of the Company (the "COMPANY BOARD"),  based upon
the recommendation of a special committee of independent  directors thereof (the
"SPECIAL  COMMITTEE"),  has determined that this Agreement and the  transactions
contemplated hereby,  including the Merger, are advisable and are fair to and in
the best interests of the Company's stockholders.

     C.  Acquirer,  the  Principals  and the  Company  desire  to  make  certain
representations,  warranties,  covenants and  agreements in connection  with the
Merger and also to prescribe  various  conditions  to the Merger as set forth in
this Agreement.

     Therefore,   in   consideration   of  the  foregoing  and  the   respective
representations,  warranties,  covenants and agreements set forth herein and for
other good and  valuable  consideration,  the parties  hereto,  intending  to be
legally bound hereby, agree as follows:

                                   ARTICLE 1.

                                   THE MERGER

     1.1 The Merger.  Upon the terms and subject to the  conditions set forth in
this Agreement,  and in accordance with the General Corporation Law of the State
of Delaware (the "DGCL") and the Limited  Liability  Company Act of the State of
Arizona (the  "ALLCA"),  the Company shall be merged with and into Acquirer (the
"MERGER") at the Effective Time. Upon the Effective Time, the separate corporate
existence  of the  Company  shall  cease  and  Acquirer  shall  continue  as the
Surviving Company (the "SURVIVING COMPANY") in accordance with the ALLCA.

     1.2 Closing.  Unless this Agreement shall have been terminated  pursuant to
Section 7.1, the closing of the Merger (the  "CLOSING") will take place no later
than the second Business Day after  satisfaction or waiver (as permitted by this
Agreement and applicable law) of the conditions  (excluding  conditions that, by
their terms,  cannot be satisfied until the Closing Date) set forth in Article 6
(the "CLOSING DATE"), unless another time or date is agreed to in writing by the

                                       1
<PAGE>
parties hereto. The Closing shall be held at the offices of Quarles & Brady LLP,

is agreed to in writing by the parties hereto.

     1.3 Effective Time.  Upon the Closing,  the parties shall (i) file with the
Secretary of State of the State of Delaware (the "DELAWARE  SECRETARY OF STATE")
a certificate  of merger or other  appropriate  documents (in any such case, the
"DELAWARE  CERTIFICATE  OF MERGER"),  executed in  accordance  with the relevant
provisions of the DGCL, (ii) file with the  Corporation  Commission of the State
of Arizona (the "ARIZONA  CORPORATION  COMMISSION")  articles of merger or other
appropriate  documents  (in any such case,  the  "ARIZONA  ARTICLES OF MERGER"),
executed in accordance with the relevant provisions of the ALLCA and (iii) shall
make all other filings,  recordings or publications  required under the DGCL and
the ALLCA in connection with the Merger.  The Merger shall become effective upon
the  filing of the  Arizona  Articles  of Merger  with the  Arizona  Corporation
Commission,  or at such later time as the  parties  may agree and specify in the
Arizona Articles of Merger (the date and time the Merger becomes effective being
herein referred to as the "EFFECTIVE TIME").

     1.4 Effects of the Merger. At and after the Effective Time, the Merger will
have the  effects  set forth in the ALLCA and the  DGCL.  Without  limiting  the
generality of the foregoing, and subject thereto, at the Effective Time, all the
properties,  rights,  privileges,  powers  and  franchises  of the  Company  and
Acquirer shall vest in the Surviving  Company,  and all debts,  liabilities  and
duties of the Company  and  Acquirer  shall  become the debts,  liabilities  and
duties of the Surviving Company.

     1.5 Articles of  Organization.  The articles of organization of Acquirer in
effect  immediately  prior  to the  Effective  Time  shall  be the  articles  of
organization of the Surviving  Company from and after the Effective Time,  until
thereafter amended as provided therein or by applicable law.

     1.6 Operating  Agreement.  The operating agreement of Acquirer as in effect
immediately prior to the Effective Time shall be the operating  agreement of the
Surviving Company from and after the Effective Time, until thereafter amended as
provided therein or by applicable law.

     1.7 Directors.  The managers of Acquirer at the Effective Time shall be the
managers of the Surviving  Company from and after the Effective Time,  until the
earlier  of their  death,  resignation,  removal  or  otherwise  ceasing to be a
manager or until their respective successors are duly elected and qualified,  as
the case may be.

issued and outstanding  immediately prior to the Effective Time that is owned by
the  Company  or any  wholly-owned  Subsidiary  of the  Company  or by  Acquirer
(including  shares of Company  Common Stock  contributed  to Acquirer by certain
stockholders of the Company prior to the Effective Time) shall  automatically be
canceled  and  retired  and  shall  cease  to  exist,   and  no  cash  or  other
consideration shall be delivered or deliverable in exchange therefor.

          (c) Conversion of Company  Common Stock.  Each share of Company Common
Stock issued and outstanding immediately prior to the Effective Time (other than
shares  canceled  pursuant to Section  1.8(b) and  Dissenting  Shares)  shall be
converted into and become the right to receive $5.00 in cash,  without  interest
thereon (the "MERGER CONSIDERATION").

          (d)  Cancellation  and Retirement of Company  Common Stock.  As of the
Effective  Time,  all  shares of Company  Common  Stock  issued and  outstanding
immediately prior to the Effective Time shall no longer be outstanding and shall
automatically  be canceled and retired and shall cease to exist, and each holder
of a  certificate  representing  any such shares of Company  Common  Stock shall
cease to have any rights with respect  thereto,  except the right to receive the
Merger  Consideration,  upon surrender of such certificate(s) in accordance with
Article 2.

     1.9  Dissenting  Shares.Notwithstanding  anything in this  Agreement to the
contrary,  including, without limitation,  Section 1.8, shares of Company Common
Stock issued and outstanding immediately prior to the Effective Time and held by
a holder who has not voted in favor of the Merger or otherwise consented thereto
in writing and who has the right to demand,  and properly demands,  an appraisal
of such  holder's  shares  in  accordance  with  Section  262 of the DGCL or any
successor  provision  (such  holder being  herein  referred to as a  "DISSENTING
STOCKHOLDER"  and such shares being herein referred to as "DISSENTING  SHARES"),
shall not be  converted  into or  represent  the  right to  receive  the  Merger
Consideration,  unless such Dissenting Stockholder fails to perfect or otherwise
loses or withdraws any such right to appraisal.  With respect to any  Dissenting
Shares, a Dissenting Stockholder shall have solely the appraisal rights provided
under Section 262 of the DGCL,  provided such  Dissenting  Stockholder  complies
with the  provisions  thereof.  If, after the Effective  Time,  such  Dissenting
Stockholder  fails to perfect or otherwise  loses or withdraws any such right to
appraisal,  each Dissenting Share held by such Dissenting  Stockholder  shall be
treated as if such share had been converted  into, as of the Effective Time, the
right to receive,  without any interest thereon, the Merger  Consideration.  The
Company shall give Acquirer  prompt notice of any demand for appraisal of shares
of Company  Common Stock  received by the Company,  and Acquirer  shall have the
right to participate in and approve  (which  approval shall not be  unreasonably
withheld or delayed) all  negotiations  and proceedings with respect to any such
demand.  The  Company  shall  not,  except  with the prior  written  consent  of
Acquirer,  make any payment with  respect to, or settle or offer to settle,  any
such demand.

                                        3

     1.10 Stock Options. Other than Company Stock Options as to which the holder
thereof  has  agreed in  writing  with the  Company  and  Acquirer  prior to the
Effective  Time to elect  different  treatment in the Merger than as provided in
this Section 1.10, each outstanding and unexercised option to purchase shares of
Company Common Stock  (collectively,  the "COMPANY STOCK OPTIONS")  issued under
the  Company's  1991 Option Plan,  as amended  through the date hereof,  whether
vested or unvested,  shall terminate and be canceled. Each employee,  officer or
director of Arizona  Instrument  who holds  exercisable  Company  Stock  Options
(including options which, by their terms,  become exercisable as a result of the
transactions contemplated hereby) shall be entitled to receive, in consideration
therefor,  a cash  payment on the  Closing  Date equal to the product of (i) the
excess, if any, of the Merger Consideration over the per share exercise price of
such Company Stock Option,  multiplied by (ii) the aggregate number of shares of
Company  Common  Stock then  subject to such  Company  Stock  Option.  Such cash
payment shall be net of any required withholding taxes.

         1.11 Stock  Purchase  Plan.  All  participants  in the Company's  Stock
Purchase  Plan of 1985,  as amended  (the  "COMPANY  STOCK  PURCHASE  PLAN" and,
together  with the  Company's  1991 Stock  Option Plan,  the "COMPANY  INCENTIVE
PLANS")  shall be  permitted to continue to withhold  pursuant to their  current
instructions  to the  trustee in  accordance  with the  provisions  of such Plan
except  that the  last  business  day of the  last  payroll  period  before  the
Effective Time shall be deemed to be the final date of the deduction  period for
the purpose of the Plan. At the Effective  Time,  the Acquirer shall pay to each
participant the difference between the purchase price as established by the Plan
and $5.00 per share of  Company  Common  Stock and the funds in the  withholding
pool shall be returned to the employee.

                                   ARTICLE 2.

                            EXCHANGE OF CERTIFICATES

     2.1 Exchange  Fund.  As of the  Effective  Time,  Acquirer or the Surviving
Company  shall  deposit,  or shall  cause to be  deposited,  with a bank,  trust
company or other exchange agent reasonably satisfactory to the Company appointed
to act as exchange agent (the  "EXCHANGE  AGENT") for the benefit of the holders
of shares of Company  Common  Stock,  cash in an  aggregate  amount equal to the
product  of (i) the  number  of  shares  of  Company  Common  Stock  outstanding
immediately  prior to the  Effective  Time  (other  than  shares to be  canceled
pursuant to Section 1.8(b) and Dissenting Shares), multiplied by (ii) the Merger
Consideration (the "EXCHANGE FUND"). The Exchange Agent shall invest all cash in
the  Exchange  Fund as  directed by the  Surviving  Company,  provided  all such
investments  shall be marketable U.S.  government  securities backed by the full
faith and credit of the U.S. government.  Interest and other income with respect
to the Exchange Fund shall accrue for the account of, and shall be promptly paid
to, the Surviving Company.

                                        4

          (a) Exchange of Certificates.  As soon as reasonably practicable after
the Effective  Time,  each holder of an outstanding  certificate or certificates
which prior  thereto  represented  shares of Company  Common Stock  shall,  upon
surrender to the Exchange Agent of such certificate(s) and acceptance thereof by
the Exchange Agent (together with the letter of transmittal described in Section
2.2(b), duly executed, and such other documents as may reasonably be required by
the  Exchange  Agent),   be  entitled  to  receive  the  amount  of  the  Merger
Consideration into which the number of shares of Company Common Stock previously
represented  by such  certificate(s)  so  surrendered  shall have been converted
pursuant to this Agreement.  After the Effective Time, there shall be no further
transfer  on the records of the Company or its  transfer  agent of  certificates
representing  shares of Company Common Stock which have been converted  pursuant
to this  Agreement  into the right to receive the Merger  Consideration,  and if
such  certificates  are presented for transfer,  they shall be canceled  against
delivery  of the  Merger  Consideration.  If the Merger  Consideration  is to be
delivered to any person  other than the person in whose name the  certificate(s)
representing  shares  of  Company  Common  Stock  surrendered  for  exchange  is
registered,  it shall be a condition of such exchange that the certificate(s) so
surrendered  shall  be  properly  endorsed  with  the  signature  guaranteed  or
otherwise  in proper  form for  transfer,  and that the person  requesting  such
exchange shall pay to the Exchange Agent any transfer or other taxes required by
reason of the  payment of the Merger  Consideration  to a person  other than the
registered  holder  thereof,  or  shall  establish  to the  satisfaction  of the
Exchange  Agent  that  such  tax  has  been  paid  or is not  applicable.  Until
surrendered as  contemplated  by this Section 2.2(a),  each  certificate  which,
prior to the Effective Time,  represented  outstanding  shares of Company Common
Stock (other than shares  canceled  pursuant to Section  1.8(b),  and Dissenting
Shares) shall be deemed at any time after the Effective  Time to represent  only
the right to receive upon such surrender the Merger  Consideration in accordance
with Section 1.8. No interest will be paid or will accrue on any cash payable as
Merger Consideration to any holder of shares of Company Common Stock.

          (b) Letter of Transmittal.  Promptly following the Effective Time (but
no later than five (5) Business Days thereafter),  the Exchange Agent shall mail
to each holder of record of a  certificate  or  certificates  which  immediately
prior to the Effective  Time  represented  outstanding  shares of Company Common
Stock,  other than shares to be canceled or retired in  accordance  with Section
1.8(b)) a letter of  transmittal  (which shall  specify that  delivery  shall be
effected, and risk of loss and title to the certificate(s) shall pass, only upon
delivery  thereof to the Exchange  Agent and shall be in such form and have such
other  provisions  as  the  Surviving   Company  may  reasonably   specify)  and
instructions  for use in  effecting  the  surrender  of such  certificate(s)  in
exchange for the Merger Consideration.

     2.3 No  Further  Ownership  Rights In  Company  Common  Stock.  The  Merger
Consideration paid upon the surrender for exchange of certificates  representing
shares of Company  Common  Stock in  accordance  with the terms of Article 1 and
this Article 2 shall be deemed to have been issued and paid in full satisfaction
of all  rights  pertaining  to the shares of Company  Common  Stock  theretofore
represented  by such  certificates,  and no holder of shares of  Company  Common
Stock shall thereby have any equity interest in the Surviving Company.

     2.4  Termination  of Exchange  Fund;  Unclaimed  Funds.  Any portion of the
Exchange  Fund that  remains  undistributed  to or  unclaimed  by the holders of
certificates  representing  shares of Company  Common  Stock for  eighteen  (18)
months after the Effective  Time shall be delivered to the Surviving  Company or
otherwise  at the  direction of the  Surviving  Company,  upon  demand,  and any
holders of such certificates who have not theretofore complied with this Article
2  shall  thereafter  look  only  to  the  Surviving   Company  for  the  Merger
Consideration  to which such  holders are  entitled  pursuant to this  Agreement
(subject to applicable  abandoned  property,  escheat or other similar laws) and
only as general  creditors  thereof  for  payment of their  claim for the Merger
Consideration.

     2.5 No Liability.  None of Acquirer,  the Company, the Surviving Company or
the Exchange Agent shall be liable to any person in respect of any cash, shares,
dividends or  distribution  payable from the Exchange Fund delivered to a public
official pursuant to any applicable abandoned property, escheat or other similar
law. If any certificates  representing  shares of Company Common Stock shall not
have been  surrendered  prior to eighteen  months after the  Effective  Time (or
immediately  prior to any  earlier  date on which the  Merger  Consideration  in
respect of such certificate would become the property of or otherwise escheat to
any  Governmental  Entity),  any such cash,  shares,  dividends or distributions
shall,  to the extent  permitted by applicable  law,  become the property of the
Surviving  Company,  free and clear of all  claims  or  interest  of any  person
previously entitled thereto.

     2.6 Lost Certificates.  If any certificate  representing  shares of Company
Common Stock has been lost, stolen or destroyed, upon the making of an affidavit
of that fact by the  person  claiming  such  certificate  to be lost,  stolen or
destroyed and, if required by the Company,  the posting by such person of a bond
in such  reasonable  amount as the Company may direct as  indemnity  against any
claim that may be made against the Company with respect to such certificate, the
Exchange  Agent will  deliver in  exchange  for such lost,  stolen or  destroyed
certificate the applicable  Merger  Consideration  with respect to the shares of
Company Common Stock formerly represented thereby.

     2.7  Withholding  Rights.  The Surviving  Company or the Exchange Agent, as
applicable,  shall be entitled  to deduct and  withhold  from the  consideration
otherwise  payable pursuant to this Agreement to any holder of shares of Company
Common Stock such amounts as the Surviving Company or the Exchange Agent, as the
case may be, may be required to deduct and  withhold  with respect to the making
of such  payment  under the  Internal  Revenue  Code of 1986,  as  amended  (the

                                        6
<PAGE>
"CODE"), or any provision of state, local or foreign tax law, including, without
limitation,  withholdings  required in connection  with  payments  under Section
1.10.  To the extent  withheld by the Surviving  Company or the Exchange  Agent,
such  withheld  amounts  shall be treated for all purposes of this  Agreement as
having been paid to the holder of shares of Company  Common  Stock in respect of
which such deduction and withholding was made.

                                   ARTICLE 3.

                         REPRESENTATIONS AND WARRANTIES

standing  in each  jurisdiction  in which  the  nature  of its  business  or the
ownership or leasing of its  properties  makes such  qualification  or licensing

individually  or in the aggregate,  would not have a Material  Adverse Effect on
the Company or would not prevent the  consummation  of the Merger by the Outside
Date. The copies of the Organizational  Documents of each of the Company and its
Subsidiaries which were previously  furnished to Acquirer are true, complete and
correct copies of such documents.  The  Subsidiaries set forth in Section 3.1(a)
of the Company Disclosure Schedule constitute all of the Company's Subsidiaries.

          (b) Capital Structure

               (i) As of the  date of this  Agreement,  the  authorized  capital
          stock of the  Company  consists  of (A)  10,000,000  shares  of Common

          Company's  treasury,  and (B) 1,000,000 shares of Preferred Stock, par

          fully  paid  and  nonassessable,  and no  class  of  capital  stock is
          entitled to preemptive rights.

<PAGE>
               (iii) All of the issued and  outstanding  shares of capital stock
          of each of the Company's Subsidiaries are owned directly or indirectly
          by the  Company  and are owned  free and clear of any  liens,  claims,
          encumbrances,  restrictions,  preemptive rights or any other claims of
          any third party ("LIENS"),  except for Liens which, individually or in
          the aggregate, would not have a Material Adverse Effect on the Company
          or would not  prevent  the  consummation  of the Merger by the Outside
          Date.

               (iv) As of the  date  of this  Agreement,  (A) no  bonds,  notes,

          outstanding,  (B) other than the  outstanding  Company  Stock  Options
          representing  in the  aggregate  the right to  purchase  up to 162,152
          shares of Company  Common  Stock,  there are no  securities,  options,
          warrants,  calls,  rights,  commitments,  agreements,  arrangements or
          undertakings  of any kind to which the  Company is a party or by which
          the Company is bound obligating the Company to issue,  deliver or sell
          or cause to be issued, delivered or sold, additional shares of capital
          stock or other  voting  securities  of the Company or  obligating  the
          Company  to  issue,  grant,  extend or enter  into any such  security,
          option, warrant, call, right,  commitment,  agreement,  arrangement or
          undertaking,  and (C)  there  are no  outstanding  obligations  of the
          Company  to  repurchase,  redeem or  otherwise  acquire  any shares of
          capital stock of the Company.

               (i) The Company has all requisite  corporate  power and authority

          Agreement  by the  requisite  vote of the  holders of  Company  Common
          Stock, to consummate the transactions contemplated hereby and thereby.
          The execution and delivery of this Agreement and the  consummation  of
          the transactions  contemplated hereby have been duly authorized by all
          necessary corporate action on the part of the Company,  subject in the
          case  of the  consummation  of the  Merger  to the  adoption  of  this
          Agreement by the holders of Company  Common Stock.  This Agreement has
          been duly  executed  and  delivered by the Company and  constitutes  a
          valid and binding obligation of the Company,  enforceable  against the
          Company in accordance  with its terms,  except as such  enforceability
          may be  limited  by  bankruptcy,  insolvency,  fraudulent  conveyance,
          reorganization,  moratorium  and similar laws relating to or affecting
          creditors rights generally or by general equity principles (regardless
          of whether such enforceability is considered in a proceeding in equity
          or at law).

               (ii) The execution and delivery of this Agreement do not, and the
          consummation of the  transactions  contemplated  hereby and compliance
          with the provisions  hereof will not, (A) violate any provision of the
          Organizational  Documents  of the  Company  or its  Subsidiaries,  (B)
          subject  to  obtaining  or making  the  consents,  approvals,  orders,
          authorizations, registrations, declarations and filings referred to in
          Section 3.1(c)(iii) below, conflict with or result in any violation of
          any statute,  law,  ordinance,  rule or regulation of any state or the

                                        8
<PAGE>
          United  States  or  any  political   subdivision  thereof  or  therein
          applicable   to  the   Company  or  any   judgment,   order,   decree,
          determination or award currently in effect, which,  individually or in
          the aggregate,  would have a Material Adverse Effect on the Company or
          would prevent the  consummation  of the Merger by the Outside Date, or
          (C)  except  as  set  forth  in  Section  3.1(c)(ii)  of  the  Company
          Disclosure Schedule,  violate,  conflict with,  constitute a breach or
          default  under  or give  rise  to a right  of  termination  under  any
          contract, loan or credit agreement,  note, mortgage,  bond, indenture,
          lease,  benefit  plan  or  other  agreement,  obligation,  instrument,
          permit,  concession,  franchise  or license to which the  Company is a
          party or by which any of its properties or assets is bound or subject,
          which, individually or in the aggregate, would have a Material Adverse
          Effect on the Company or would prevent the  consummation of the Merger
          by the Outside Date.

               (iii)  No  consent,   approval,  order  or  authorization  of  or
          registration, declaration or filing with, any supranational, national,
          state,   municipal   or   local   government,   any   instrumentality,
          subdivision,  court,  administrative  agency  or  commission  or other
          authority thereof, or any quasi-governmental  authority or any private
          body exercising any regulatory, taxing or other governmental authority
          (a  "GOVERNMENTAL  ENTITY"),  which has not been  received or made, is
          required  by or with  respect  to the  Company  or any  Subsidiary  in
          connection  with the execution  and delivery of this  Agreement by the
          Company  or the  consummation  by  the  Company  of  the  transactions
          contemplated hereby, except for (A) the filing with the Securities and
          Exchange  Commission  (the "SEC") of a proxy  statement in  connection
          with the  Stockholders  Meeting (such proxy  statement,  including any
          preliminary version thereof,  in either case, as amended,  modified or
          supplemented from time to time, the "PROXY STATEMENT"), (B) the filing
          with the SEC of a Rule 13e-3  Transaction  Statement on Schedule 13E-3
          (the "SCHEDULE  13E-3") under the Securities  Exchange Act of 1934, as
          amended (the "EXCHANGE ACT"), (C) state securities or "blue sky" laws,
          (D) any other  filings or reports  required  under the Exchange Act or
          the rules and  regulations  promulgated  thereunder in connection with
          the  transactions  contemplated by this Agreement,  (E) the filing and
          recordation of appropriate  merger or other  documents under the DGCL,
          (F)  compliance  with the rules and  regulations  of The Nasdaq  Stock
          Market  ("NASDAQ"),  (G) antitrust or other  competition laws of other
          jurisdictions,    and   (H)   such   consents,    approvals,   orders,
          authorizations, registrations, declarations and filings the failure of
          which to make or obtain  could not  reasonably  be  expected to have a
          Material  Adverse Effect on the Company or to prevent the consummation
          of the Merger by the Outside Date.

          (d) Reports  and  Financial  Statements.  Since  January 1, 1999,  the
Company has filed all required reports,  schedules,  forms, statements and other
documents required to be filed by it with the SEC (collectively, the "REPORTS").
None of the Company's Subsidiaries is required to file any form, report or other
document  with  the  SEC.  Each of the  financial  statements  and  the  related
schedules and notes thereto included in the Reports (or incorporated  therein by
reference) present fairly, in all material respects,  the consolidated financial

                                        9
<PAGE>
position and  consolidated  results of operations  and cash flows of the Company
and its  Subsidiaries as of the respective  dates or for the respective  periods
set  forth  therein,  all  in  conformity  with  generally  accepted  accounting
principles  ("GAAP")  (except,  in  the  case  of  interim  unaudited  financial
statements,  as permitted by Form 10-Q) consistently  applied during the periods
involved except as otherwise noted therein,  and subject, in the case of interim
unaudited  financial  statements,  to normal and recurring year-end  adjustments
that have not been and are not reasonably expected to be material in amount, and
such financial  statements  complied as to form as of their  respective dates in
all material  respects with the  Securities  Act, the Exchange Act and the rules
and regulations promulgated  thereunder.  Each Report was prepared in accordance
with the  requirements of the Securities Act, the Exchange Act and the rules and
regulations  promulgated thereunder and did not, on the date of effectiveness in
the case of any registration  statement under the Securities Act, on the date of
mailing in the case of any proxy  statement  under the  Exchange  Act and on the
date of filing in the case of any other Report (and, if amended or superseded by
a filing prior to the date of this Agreement or of the Closing Date, then on the
date of such filing), contain any untrue statement of a material fact or omit to
state a material  fact  required to be stated  therein or  necessary to make the
statements  therein,  in light of the circumstances  under which they were made,
not misleading.

          (e) Disclosure  Documents.  The Proxy Statement and the Schedule 13E-3
will comply as to form in all material  respects  with the  requirements  of the
Exchange Act and the rules and regulations promulgated  thereunder.  None of the
information  supplied  or to  be  supplied  by  the  Company  for  inclusion  or
incorporation  by reference in (i) the Proxy  Statement,  at the date such Proxy
Statement is first mailed to the  Company's  stockholders  or at the time of the
Stockholders Meeting, or (ii) the Schedule 13E-3, at the time of filing with the
SEC (and at any time such  Proxy  Statement  or  Schedule  13E-3 is  amended  or
supplemented),  will contain any untrue  statement of a material fact or omit to
state a material  fact  required to be stated  therein or  necessary in order to
make the statements  therein, in light of the circumstances under which they are
made, not misleading.  Notwithstanding the foregoing  provisions of this Section

forth in Section 3.2(i),  the  affirmative  vote of the holders of a majority of

and shall be paid upon consummation of the Merger.

received the written opinion of Peacock, Hislop, Staley & Given, Inc., financial
advisor to the Special Committee ("PEACOCK,  HISLOP"),  dated March 28, 2000, to
the effect that,  subject to the  qualifications and limitations stated therein,
the  consideration  to be received  by the  holders of shares of Company  Common
Stock  (other  than  Acquirer)  in the  Merger  is fair to such  holders  from a
financial  point of view.  The Special  Committee  has furnished an accurate and
complete copy of such written opinion to Acquirer.

          (k) Contracts. All material contracts of the Company are in full force
and effect and  enforceable  against  each party  thereto.  There does not exist

have or result in, a Material  Adverse  Effect on the  Company and (ii) have not

applicable  Environmental  Laws,  and there are no past or present  (or,  to the

practices,  incidents,  actions, omissions or plans (i) which may interfere with
or prevent  compliance or continued  compliance with  Environmental Laws or with
any order issued, entered, promulgated or approved thereunder, or (ii) which may
subject the Company to damages,  penalties,  injunctive relief, or cleanup costs
under any  Environmental  Laws or pursuant to any  third-party  claim,  or which
require or are likely to require reporting,  cleanup,  removal, remedial action,
or other response pursuant to Environmental Laws or a third party claim, in each
case except to the extent that any of the foregoing  would not,  individually or
in the aggregate, result in a Material Adverse Effect on the Company.

times  has been in  material  compliance  with all  applicable  Laws  (including

threatened   litigation,    Environmental   Claim,   arbitration,    proceeding,
governmental  investigation or inquiry involving the Company which, if adversely
determined,  would result in a Material Adverse Effect on the Company. There are
no actions,  suits or  proceedings  pending or, to the knowledge of the Company,
proposed or threatened,  by any Person or Governmental  Authority which question
the legality,  validity,  or propriety of the transactions  contemplated by this
Agreement.

          (o) Tax Matters.

               (i) The  Company  has filed all  Income Tax  Returns  that it was
          required  to file,  and has paid or made  provision  to pay all Income
          Taxes shown thereon as owing,  except where the failure to file Income
          Tax Returns or to pay Income  Taxes would not have a Material  Adverse
          Effect on the Company.

               (iii) The Company is not a party to any Income Tax  allocation or
          sharing agreement.

     Each of the  representations and warranties in this Section 3.1 (other than
those  set forth in  Sections  3.1(g),  (i) and (j)) is  qualified  by,  and the
Company  Disclosure  Schedule  shall be  deemed  to  disclose  in  qualification
thereof, any facts, circumstances,  conditions or events actually known to or by
the  Principals  or any of the  persons  set forth in Section 3.1 of the Company
Disclosure Schedule.

     3.2 Representations and Warranties of Acquirer and the Principals. Acquirer
and the Principals,  jointly and severally, represent and warrant to the Company
as follows:

          (a) Organization, Standing and Power. Acquirer has been duly organized
and is validly  existing and in good standing under the laws of its jurisdiction
of  incorporation  and has the power and  authority  to carry on its business as
presently being conducted and to own, operate and lease its properties. Acquirer
is duly  qualified  or licensed to do business  and is in good  standing in each
jurisdiction  in which the nature of its business or the ownership or leasing of
its properties makes such qualification or licensing necessary, except where the
failure to be so qualified or licensed, either individually or in the aggregate,
would not have a Material  Adverse  Effect on  Acquirer or would not prevent the
consummation of the Merger by the Outside Date. The copies of the Organizational
Documents of Acquirer which were  previously  furnished to the Company are true,
complete and correct copies of such documents.

          (b) Capital Structure.  As of the date hereof,  none of the issued and
outstanding  membership units of Acquirer are owned by any person other than the
Principals and G. James Hays. As of the date hereof, (A) Acquirer owns no shares
of Company Common Stock,  (B) the Principals and G. James Hays own the number of
shares of Company  Common Stock set forth opposite their names on Exhibit A, and
(C) the  Principals  own the  number  of  Acquirer  membership  units  set forth
opposite their names on Exhibit A.

          (c) Authority; No Conflicts

               (i) Acquirer has all requisite  limited  liability  company power
          and  authority  to enter into this  Agreement  and to  consummate  the
          transactions  contemplated  hereby. The execution and delivery of this
          Agreement and the consummation of the transactions contemplated hereby
          have been duly authorized by all necessary  limited  liability company
          action on the part of Acquirer.  This Agreement has been duly executed

                                       13
<PAGE>
          and  delivered  by  Acquirer  and  constitutes  a  valid  and  binding
          agreement of Acquirer,  enforceable  against it in accordance with its
          terms,  except as such  enforceability  may be limited by  bankruptcy,
          insolvency,  fraudulent  conveyance,  reorganization,  moratorium  and
          other  similar  laws  relating  to  or  affecting   creditors   rights
          generally, or by general equity principles (regardless of whether such
          enforceability is considered in a proceeding in equity or at law).

               (ii) The execution and delivery of this Agreement do not, and the
          consummation of the  transactions  contemplated  hereby and compliance
          with the provisions  hereof will not, (A) violate any provision of the
          Organizational  Documents  of  Acquirer,  (B) subject to  obtaining or
          making the consents, approvals, orders, authorizations, registrations,
          declarations  and filings  referred to in Section  3.2(c)(iii)  below,
          conflict  with or result in any  violation of or  constitute a default
          (with or without  notice or lapse of time, or both) under any statute,
          law,  ordinance,  rule or regulation of any state or the United States
          or any  political  subdivision  thereof or  therein  or any  judgment,
          order,  decree,  determination  or award  currently in effect,  which,
          individually or in the aggregate, would have a Material Adverse Effect
          on Acquirer or would  prevent  the  consummation  of the Merger by the
          Outside Date, or (C) violate,  conflict  with,  constitute a breach or
          default  under  or give  rise  to a right  of  termination  under  any
          contract, loan or credit agreement,  note, mortgage,  bond, indenture,
          lease (other than  required  consents of  landlords),  benefit plan or
          other  agreement  ,  obligation,   instrument,   permit,   concession,
          franchise  or license to which  Acquirer is a party or by which any of
          its properties or assets is bound or subject,  which,  individually or
          in the aggregate,  would have a Material Adverse Effect on Acquirer or
          would prevent the consummation of the Merger by the Outside Date.

               (iii)  No  consent,  approval,  order  or  authorization  of,  or
          registration,  declaration  or filing with, any  Governmental  Entity,
          which has not been received or made, is required by or with respect to
          Acquirer  in  connection  with  the  execution  and  delivery  of this
          Agreement  by  Acquirer  or  the   consummation  by  Acquirer  of  the
          transactions  contemplated hereby,  except for (A) state securities or
          "blue  sky"  laws,  (B) any  filings  or  reports  required  under the
          Exchange Act or the rules and  regulations  promulgated  thereunder in
          connection with the transactions  contemplated by this Agreement,  (C)
          the filing and  recordation of appropriate  merger or other  documents
          under the ALLCA and DGCL, (D) antitrust or other  competition  laws of
          other  jurisdictions  and  (E)  such  consents,   approvals,   orders,
          authorizations, registrations, declarations and filings the failure of
          which to make or obtain  could not  reasonably  be  expected to have a
          Material  Adverse Effect on Acquirer or to prevent the consummation of
          the Merger by the Outside Date.

          (d)  Financing.  Acquirer  has  cash  on hand  or has  received  fully
executed written commitments,  copies of which are attached as Exhibit C hereto,
from the persons indicated thereon (collectively, the "COMMITMENTS") to provide,

                                       14
<PAGE>
in the aggregate, monies sufficient to fund the consummation of the transactions
contemplated by this Agreement,  including the Merger and the payments  required
under  Section 1.10 in respect of Company Stock  Options,  and satisfy all other
costs and  expenses  arising in  connection  therewith  (the  "FINANCING").  The
Commitments  have been accepted by Acquirer and the fees due upon  acceptance of
such Commitments have been paid in full. As of the date hereof,  the Commitments
have not been amended or modified from those  attached as Exhibit C and there is
no breach or default existing,  or with notice or the passage of time may exist,
under the Commitments. Acquirer has no reason to believe that any of the matters
set forth in the Company  Disclosure  Schedule will result in the failure of any
of the conditions  precedent to the  consummation of the Financing  contemplated
hereby stated in each of the Commitments.

          (e) Disclosure  Documents.  None of the information  supplied or to be
supplied by Acquirer  for  inclusion  or  incorporation  by reference in (A) the
Proxy  Statement,  at the date  such  Proxy  Statement  is first  mailed  to the
Company's  stockholders or at the time of the Stockholders  Meeting,  or (B) the
Schedule  13E-3,  at the time of filing with the SEC (and at any time such Proxy
Statement or Schedule 13E-3 is amended or supplemented), will contain any untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they are made, not misleading.

          (f) No Vote Required.  No vote of the members of Acquirer is necessary
to approve this Agreement and the  transactions  contemplated  hereby other than
those obtained by Acquirer as of the date hereof.

          (g) Brokers or Finders. No agent, broker, investment banker, financial
advisor  or  other  firm  or  person  is or will be  entitled  to any  broker's,
financial  advisory or finder's fee or any other  similar  commission  or fee in
connection with any of the  transactions  contemplated by this Agreement,  based
upon arrangements made by or on behalf of Acquirer.

          (h) No Business  Activities.  Acquirer is not a party to any  material
agreement nor has it conducted any activities  other than in connection with its
organization,  the preparation,  negotiation and execution of this Agreement and
the  Commitments,  the procurement of the Financing and the  consummation of the
transactions  contemplated  hereby.  Except for its  ownership  of the shares of
Company  Common  Stock  set  forth in  Section  3.2(b),  Acquirer  does not own,
directly or  indirectly,  any capital stock or other  ownership  interest in any
person and Acquirer has no Subsidiaries.

          (i) State Takeover Laws.

                                       15
<PAGE>
               (i) The  actions  of the  Company  Board  set  forth  in  Section
          3.1(i)(i)  are  sufficient  to render  inapplicable  to the Merger the
          provisions of Section 203 of the DGCL.

               (ii) The  actions  of the  Company  Board  set  forth in  Section
          3.1(i)(i)  are  sufficient  to render  inapplicable  to the merger the
          provisions of Section 10-2701 of the Arizona Business Corporation Law.

          (j) No Conflicting Knowledge.  Each of the Principals has reviewed the
representations  and  warranties  of the Company set forth in Section 3.1 hereof
and to his actual  knowledge (i) such  representations  and  warranties  (to the
extent supplemented or modified by the Company Disclosure Schedule) are true and
correct in all material  respects and (ii) such  representations  and warranties
that  are by their  terms  qualified  as to  materiality  by the term  "Material
Adverse Effect" or similar terms are true and correct.

capital   structure  in  a  manner  which  would  materially  delay  the  timely
consummation  of the Merger or  prevent  the  consummation  of the Merger by the
Outside Date.

          (c) Other Actions.  Neither Acquirer nor the Principals shall take any
action that could  reasonably be expected to result in any of the  conditions to
the Merger set forth in Article 6 not being satisfied.

     4.3 Advice of Changes;  Government  Filings.  Each party  hereto  shall (a)
confer on a regular and frequent basis with the other party,  (b) report (to the
extent  permitted  by  law,   regulation  and  any  applicable   confidentiality
agreement)  to the other on  operational  matters,  and (c) promptly  advise the
other  orally and in writing of (i) any  representation  or warranty  made by it
contained in this Agreement that is qualified as to materiality  becoming untrue
or any such  representation or warranty that is not so qualified becoming untrue
in any material respect, (ii) the failure by it (A) to comply with or satisfy in
any respect any covenant, condition or agreement required to be complied with or
satisfied by it under this  Agreement that is qualified as to materiality or (B)
to comply with or satisfy in any  material  respect any  covenant,  condition or
agreement  required to be complied with or satisfied by it under this  Agreement
that is not so  qualified  as to  materiality,  or (iii)  any  change,  event or
circumstance  that has had or could  reasonably  be  expected to have a Material
Adverse  Effect on such party or  materially  adversely  affect  its  ability to
consummate  the Merger by the  Outside  Date;  provided,  however,  that no such
notification  shall  affect  the  representations,   warranties,   covenants  or
agreements of the parties or the  conditions to the  obligations  of the parties
under this Agreement. The Company shall file all reports required to be filed by
it with the SEC (and all other  Governmental  Entities) between the date of this
Agreement  and the Effective  Time and shall (to the extent  permitted by law or
regulation or any  applicable  confidentiality  agreement)  deliver to the other
party copies of all such reports  promptly after the same are filed.  Subject to
applicable laws relating to the exchange of information, each of the Company and
Acquirer shall have the right to review in advance and approve  (which  approval
shall not be unreasonably  withheld or delayed),  and to the extent  practicable
each will consult with the other with respect to, all the  information  relating
to the other party, which appears in any filings,  announcements or publications
made with,  or  written  materials  submitted  to,  any  Governmental  Entity in
connection with the transactions  contemplated by this Agreement.  In exercising
the foregoing right,  each of the parties hereto agrees to act reasonably and as
promptly as practicable.  Each party agrees that, to the extent practicable,  it

                                       19
<PAGE>
will consult with the other party with respect to the  obtaining of all permits,
consents,  approvals and  authorizations  of all third parties and  Governmental
Entities  necessary or advisable to consummate the transactions  contemplated by
this  Agreement and each party will keep the other party  apprised of the status
of matters relating to completion of the transactions contemplated hereby.

hereby,  including the Merger, by obtaining the Required Company Vote. Except as
otherwise   provided  in  Section  5.5,  the  Company  Board,   based  upon  the

solicit such approval and adoption.

          (b) As soon as practicable  following the date of this Agreement,  the
Company and Acquirer shall jointly prepare,  and the Company shall file with the
SEC, the Proxy  Statement and the Schedule  13E-3.  Acquirer will cooperate with
the Company in connection  with the  preparation  and filing with the SEC of the

furnishing  the Company  upon  request  with any and all  information  regarding
Acquirer,  the  Principals  or their  respective  Affiliates,  the plans of such
persons  for  the  Surviving  Company  after  the  Effective  Time,  information
regarding the Financing and all other matters and information as may be required
to be set forth  therein  under the  Exchange  Act or the rules and  regulations
promulgated  thereunder.  The Company shall use  reasonable  best efforts (i) to

withheld or delayed) all filings with the SEC and all mailings to the  Company's
stockholders  in  connection  with the  Merger  prior to the  filing or  mailing
thereof. The Company and Acquirer each agree to correct any information provided
by such party for use in the Proxy Statement or the Schedule 13E-3 which becomes

          (c) Each  party  shall  notify  the other  party  promptly  of (i) the
receipt of any  notices,  comments or other  communications  from the SEC or any
other Governmental Authority, and (ii) any requests by the SEC for amendments or
supplements  to the Proxy  Statement  or the  Schedule  13E-3 or for  additional

correspondence between such party or its representatives on the one hand and the
SEC or  members  of its  staff on the  other  hand  with  respect  to the  Proxy
Statement or the Schedule 13E-3.

          (d) If,  at any time  prior to the  Stockholders  Meeting,  any  event
should  occur  relating to the Company or its  Subsidiaries  which should be set
forth in an  amendment  of,  or a  supplement  to,  the Proxy  Statement  or the
Schedule 13E-3, the Company will promptly inform Acquirer. If, at any time prior
to the  Stockholders  Meeting,  any event should  occur  relating to Acquirer or
relating to the plans of Acquirer for the Surviving  Company after the Effective
Time or the  Financing,  which  should  be set  forth in an  amendment  of, or a
supplement to, the Proxy Statement or the Schedule 13E-3, Acquirer will promptly
inform the Company.  In any such case, the Company or Acquirer,  as the case may
be, with the cooperation of the other party, shall, upon learning of such event,
promptly  prepare,  file and, if required,  mail such amendment or supplement to
the Company's stockholders;  provided that, prior to such filing or mailing, the
parties shall approve (which approval,  with respect to either party,  shall not
be  unreasonably  withheld or delayed) the form and content of such amendment or
supplement.

     5.2 Access to Information; Confidentiality.

          (a) From and after the date  hereof  until the  Effective  Time,  upon
reasonable notice, each of the Company and Acquirer shall (and shall cause their
respective  Subsidiaries,  if any, to the extent permitted by the Organizational
Documents  or other  pertinent  agreements  of such  entity,  to)  afford to the
officers,  employees,   accountants,   counsel,  financial  advisors  and  other
representatives  of the other party  reasonable  access during  normal  business
hours, to all its properties, books, contracts,  commitments and records and its
officers,  employees,  representatives and lenders and, during such period, each
of the Company and Acquirer shall (and shall cause its Subsidiaries,  if any, to
the  extent  permitted  by  the  Organizational  Documents  or  other  pertinent
agreements of such entity, to) furnish promptly to the other party (a) a copy of
each  report,  schedule,   registration  statement  and  other  document  filed,
published,  announced  or  received  by it during  such  period  pursuant to the
requirements  of Federal or state  securities  laws, as  applicable  (other than
reports or  documents  which  such  party is not  permitted  to  disclose  under
applicable  law),  and (b)  consistent  with its  legal  obligations,  all other
information concerning its business, properties and personnel as the other party
may reasonably request; PROVIDED,  HOWEVER, each of the Company and Acquirer may
restrict  the  foregoing  access to the extent  that (i) a  Governmental  Entity
requires  such  party  or any of its  Subsidiaries  to  restrict  access  to any
properties or information  reasonably  related to any such contract on the basis
of applicable laws and regulations,  or (ii) any law, treaty, rule or regulation
of any Governmental  Entity  applicable to such party or any of its Subsidiaries
requires  such  party  or any of its  Subsidiaries  to  restrict  access  to any
properties or information.

                                       21
<PAGE>
          (b) Each of the Acquirer and the Principals shall use the Confidential
Information  solely for the purpose of evaluating the transactions  contemplated
hereby or any modification of such  transactions and for no other purpose.  Each
of Acquirer, and the Principals,  on behalf of themselves and all other Acquirer
Parties, agrees to keep all Confidential Information confidential and shall not,
without  the  prior  written  consent  of  Company,  disclose  any  Confidential
Information  to any third party,  in whole or in part.  Each of Acquirer and the
Principals shall not disclose the Confidential Information to any other Acquirer
Party except those who have an actual need to know the Confidential  Information
for the purpose of evaluating  the  transactions  contemplated  hereby,  who are
informed of the  confidential  nature of the  Confidential  Information  and who
agree to be bound  by this  Section  5.2(b)  ("PERMITTED  RECIPIENTS").  Each of
Acquirer and the Principals shall be responsible for any breach of any provision
of this Section 5.2(b) by its Permitted Recipients.  Upon the Company's request,
each Acquirer Party shall:  (i) destroy or, at the Company's  option,  return to
the Company all Confidential  Information  which is in tangible form,  including
any copies  thereof,  and  destroy  all  Confidential  Information  provided  on
computer  disks  or tape or in  other  digital  format  and  all  abstracts  and
summaries of Confidential Information and references thereto which may have been
prepared  by any  Acquirer  Party;  and (b)  certify  to the  Company  that  all
Confidential  Information  has been  returned or  destroyed  as requested by the
Company.

     In the event that any Acquirer Party becomes legally  compelled to disclose
any  Confidential  Information,  Acquirer  shall provide the Company with prompt
notice,  if lawful,  so that the  Company may seek a  protective  order or other
appropriate  remedy and/or waive  compliance with the provisions of this Section
5.2(b).  In the event such protective order or other remedy is not obtained,  or
the Company  waives  compliance  with the  provisions  of this  Section  5.2(b),
Acquirer  shall  furnish  or permit to be  furnished  only that  portion  of the
Confidential  Information  which  Acquirer  is advised by its counsel is legally
required to be  furnished,  and  Acquirer  shall use its best  efforts to obtain
assurances that such Confidential Information shall be treated confidentially by
the recipient thereof.

     Acquirer  acknowledges  and agrees that any breach or threatened  breach of
the  terms of this  Section  5.2(b)  regarding  the  treatment  of  Confidential
Information may result in irreparable  damage to the Company for which there may
be no adequate  remedy at law.  Therefore,  each of Acquirer and the  Principals
agrees that in the event of any breach of this Section 5.2(b) by it or any other
Acquirer  Party  or by  any  third  party  to  whom  any  Acquirer  Party  makes
Confidential  Information available,  the Company shall be entitled, in addition

                                       22
<PAGE>
to any other rights and remedies available to it, to specific enforcement of the
terms of this Section 5.2(b) and/or  injunctive  relief  requiring the immediate
return of all  Confidential  Information in the possession of any Acquirer Party
or any such third party and  enjoining  all Acquirer  Parties and any parties to
which any Acquirer Party has made Confidential  Information available from using
Confidential  Information  in violation of this Section  5.2(b),  in either case
without the  necessity of showing or proving  that any actual  damages have been
sustained. Company shall be entitled to recover from Acquirer and the Principals
the costs of litigation, including reasonable attorneys' fees, incurred by it in
any successful  legal or equitable  action taken by it to enforce the provisions
of this Section 5.2(b).

     5.3 Approval and  Consents;  Cooperation.  Each of the Company and Acquirer
shall  cooperate  with each  other and use (and  shall  cause  their  respective
Subsidiaries,  if any, to use) their respective  reasonable best efforts to take
or cause  to be  taken  all  actions,  and do or  cause  to be done all  things,
necessary,  proper or advisable on their part to consummate  and make  effective
the Merger and the other transactions  contemplated by this Agreement (including
the  procurement  of the Financing and the  satisfaction  of the  conditions set
forth in Article 6) as soon as  practicable,  including (i) preparing and filing
as  promptly  as  practicable  all  documentation  to effect  all  applications,
notices,  petitions,  filings,  tax ruling  requests and other  documents and to
obtain as promptly as  practicable  all  consents,  waivers,  licenses,  orders,
registrations,  approvals,  permits, tax rulings and authorizations necessary to
be obtained  from any third  party  and/or any  Governmental  Entity in order to
consummate  the  Merger or any of the other  transactions  contemplated  by this
Agreement,  other than those as to which the failure to so prepare and file such
documentation  would not have a Material Adverse Effect on any of the Company or
Acquirer as the case may be, or would not prevent the consummation of the Merger
by the Outside Date (the "REQUIRED  REGULATORY  APPROVALS")  and (ii) taking all
reasonable  steps as may be  necessary  to obtain all such  Required  Regulatory
Approvals.  The Company and  Acquirer  each  shall,  upon  request by the other,
furnish the other with all  information  concerning  itself,  its  Subsidiaries,
directors, officers and stockholders and such other matters as may reasonably be
necessary or  advisable in  connection  with the Proxy  Statement,  the Schedule
13E-3 or any Required  Regulatory  Approvals  or other  statement,  filing,  tax
ruling  request,  notice or  application  made by or on  behalf of the  Company,
Acquirer or any of their  respective  Subsidiaries to any third party and/or any
Governmental  Entity in  connection  with the  Merger or the other  transactions
contemplated by this Agreement.

     5.4  Financing.  Acquirer  and  each  Principal  shall  use its or his best
efforts (i) to consummate the Financing on terms consistent with the Commitments
or  such  other   financing  or  terms  as  shall  be  mutually  and  reasonably
satisfactory to the Company and Acquirer on or before the Closing Date, and (ii)
to execute and deliver definitive  agreements with respect to the Financing upon
the terms provided in the  Commitments or such other financing or terms as shall
be  mutually  and  reasonably  satisfactory  to the Company  and  Acquirer  (the
"DEFINITIVE FINANCING  AGREEMENTS") on or before the Closing Date; provided that
best efforts of Acquirer and each Principal as used in this Section 5.4 shall in
no event  require  Acquirer  and the  Principals  to agree  to  financing  terms
materially more adverse to Acquirer than those provided for in the  Commitments.
For purposes of this Section 5.4, an increase of 1 1/2 percentage points or more
in the effective interest rates of the Financing compared to the rates in effect
on the date hereof, shall be deemed a material adverse change from the financing
terms provided for in the Commitments. Acquirer and each Principal shall use its

                                       23
<PAGE>
or his best efforts to keep the  Commitments  in effect until the earlier of the
Closing Date or the termination of this Agreement (which shall include,  but not
be limited to,  obtaining any necessary  extensions of the  Commitments  through
such date) and to satisfy on or before the Closing Date all  requirements of the
Commitments  and the  Definitive  Financing  Agreements  which are conditions to
closing the  transactions  constituting  the  Financing  and to drawing the cash
proceeds thereunder.

     5.5  Acquisition  Proposals.  During  the  period  from  the  date  of this
Agreement  and  continuing   until  the  Effective  Time  (except  as  expressly
contemplated or permitted by this Agreement or to the extent that Acquirer shall
otherwise consent in writing,  which consent shall not be unreasonably  withheld
or delayed):

          (a) The Company  agrees that the  directors  constituting  the Special
Committee  shall not, and the Company shall use its  reasonable  best efforts to
cause  the  Company's  other   Representatives   and  the  Special   Committee's
Representatives not to, directly or indirectly, initiate, or solicit the making,
submission or announcement of any Acquisition Proposal. As used herein, the term
"ACQUISITION  PROPOSAL" means and includes any offer,  indication of interest or
proposal (other than by Acquirer or any of the Principals or any of them jointly
with any other person)  relating to a transaction  involving the  acquisition of
stock or  assets  of the  Company  which  would  upon the  consummation  thereof
materially  and adversely  affect the ability of the parties to  consummate  the
transactions contemplated hereby, including the Merger.

          (b) The Company  agrees that the  directors  constituting  the Special
Committee  shall not, and the Company shall use its  reasonable  best efforts to
cause  the  Company's  other   Representatives   and  the  Special   Committee's
Representatives  not to,  directly  or  indirectly,  engage  in  discussions  or
negotiations,  furnish or provide any  non-public  information or data or afford
access to the properties,  books,  records and Representatives of the Company to
any  Person  with  respect  to any  Acquisition  Proposal.  Notwithstanding  the
foregoing,  the Company,  the Company Board or the Special Committee may (or may
direct any Representative of the Company or the Special Committee to) (i) engage
in discussions or negotiations  regarding an Acquisition Proposal,  (ii) furnish
or provide  non-public  information,  or (iii) afford access to the  properties,
books,  records and  Representatives of the Company,  with or to any Person that
has made and has  pending  a written  Acquisition  Proposal  which  the  Special
Committee  has  determined  in good  faith  is  reasonably  likely  to lead to a
Superior Proposal; provided that, prior to taking any action described in any of
the  foregoing  clauses  (i),  (ii) or (iii),  such  Person has  entered  into a
confidentiality  agreement for the benefit of the Company on  substantially  the
same terms as set forth in Section 5.2 hereof or on terms more  favorable to the
Company.  The Company shall  promptly  notify  Acquirer of the  Company's  first
receipt  of a  written  Acquisition  Proposal  and of  the  material  terms  and
conditions thereof.  Notwithstanding anything to the contrary in this Agreement,
the Company  shall not be required to disclose to Acquirer  the  identity of the
Person making any such Acquisition  Proposal and shall have no duty to notify or
update  Acquirer on the status of  discussions  or  negotiations  (including the
status of such  Acquisition  Proposal or any  amendments or proposed  amendments

                                       24
<PAGE>
thereto) between the Company and such Person. Furthermore,  nothing contained in
this  Agreement  shall  prevent or otherwise  restrict the Company,  the Company
Board or the Special  Committee  from  complying  with Rule 14e-2 and Rule 14d-9
promulgated under the Exchange Act with regard to an Acquisition Proposal.

          (c) Subject to Section 7.1 hereof,  at any time prior to the  approval
of this Agreement by the  stockholders of the Company,  the Company Board or the
Special Committee may (i) withdraw or modify its  recommendation  of, or refrain
from  recommending,  the Merger and this  Agreement,  (ii)  approve any Superior
Proposal  or declare a  Superior  Proposal  advisable  or  recommend  a Superior
Proposal to the Company's  stockholders or (iii) cause the Company to enter into
any  definitive  acquisition  agreement with respect to a Superior  Proposal.  A
"SUPERIOR  PROPOSAL"  shall  mean an  Acquisition  Proposal  which  the  Special
Committee  determines  in good  faith,  after  consultation  with and giving due
consideration to the advice of its legal and financial advisors, (x) is at least
as likely as the  Merger to be  consummated,  taking  into  account  all  legal,
financial,  regulatory,  tax and other aspects of such Acquisition  Proposal and
the conditions and contingencies  thereof, (y) is one as to which there has been
provided evidence of cash on hand or readily available  financing under existing
lines of credit or written  commitments  sufficient to fund the  consummation of
such  Acquisition  Proposal,  and  (z)  would,  if  consummated,   result  in  a
transaction more favorable to the Company's  stockholders from a financial point
of view than the transactions contemplated by this Agreement.

          (d) The Company  represents  and warrants that, as of the date hereof,
it has  ceased and has  caused to be  terminated  all  existing  discussions  or
negotiations with any parties conducted heretofore in respect of any Acquisition
Proposal.

     5.6 Employee Benefits; Company Plans.

          (a) Subject to Sections  5.6(b) and 5.6 (c) below,  for a period of at
least one (1) year  immediately  following the Closing Date,  Acquirer  shall or
shall cause the Surviving  Company to maintain in effect employee  benefit plans
and arrangements  (not including equity  incentive  arrangements)  which provide
benefits which have a value which is substantially comparable, in the aggregate,
to the benefits provided by the Company as of the date hereof.

          (b)  Unless  otherwise  agreed to in  writing  by the  employee  party
thereto,  Acquirer  shall  cause the  Surviving  Company  to honor  all  written
employment,  bonus,  severance and termination plans and agreements of employees
of the  Company and its  Subsidiaries  in effect on or prior to the date of this
Agreement in accordance with their terms,  including,  without  limitation,  the
treatment  of the  transactions  contemplated  hereby as a "change  of  control"
thereunder.

                                       25
<PAGE>
     5.7 Fees and  Expenses.  All  Expenses  incurred  in  connection  with this
Agreement and the  transactions  contemplated  hereby shall be paid by the party
incurring such Expenses, except (a) if the Merger is consummated,  the Surviving
Company shall pay, or cause to be paid,  any real property  transfer tax imposed
on any  holder of shares of  capital  stock of the  Company  resulting  from the
Merger,  (b) the Expenses  incurred in connection with the printing,  filing and
mailing  to  stockholders  of  the  Proxy  Statement  and  the  solicitation  of
stockholder  approvals  shall be paid by the  Company,  and (c) as  provided  in
Section 7.2.

     5.8  Indemnification;  Directors'  and Officers'  Insurance.  The Surviving
Company shall cause to be maintained in effect (a) for a period of six (6) years
after the Effective Time, the provisions regarding indemnification of current or
former  officers and  directors  (the  "INDEMNIFIED  PARTIES")  contained in the
Organizational  Documents  of  the  Company  or  its  Subsidiaries  and  in  any
agreements  between an Indemnified  Party and the Company or its Subsidiaries as
of the date hereof,  and (b) for a period of six (6) years, the current policies
of  directors'  and  officers'   liability  insurance  and  fiduciary  liability
insurance  maintained by the Company  (provided  that the Surviving  Company may
substitute  therefor policies with an insurer of equal claims paying ratings and
of at least the same coverage and amounts  containing terms and conditions which
are, in the  aggregate,  no less  advantageous  to the insured)  with respect to
claims  arising  from facts or events that  occurred on or before the  Effective
Time.  This  covenant  is  intended  to be for the  benefit  of,  and  shall  be
enforceable by, each of the Indemnified  Parties and their  respective heirs and
legal representatives.

     5.9  Public  Announcements.  From and  after  the  date  hereof  until  the
Effective  Time, the Company and Acquirer shall use all reasonable  best efforts
to develop a joint  communications  plan and each party shall use all reasonable
best efforts (i) to ensure that all press  releases and other public  statements
with respect to the  transactions  contemplated  hereby shall be consistent with
such joint communications plan, and (ii) unless otherwise required by applicable
law or by obligations  pursuant to any listing agreement with or rules of Nasdaq
or any securities exchange,  to consult with each other before issuing any press
release or otherwise  making any public statement with respect to this Agreement
or the transactions contemplated hereby.

     5.10  Takeover  Statutes.  The Company  and the  Company  Board or any duly
authorized  committee thereof,  including the Special Committee,  subject to its
fiduciary  duties,  shall  grant  such  approvals  and take such  actions as are
necessary to render  Section 203 of the DGCL and any other  applicable  takeover
statute  inapplicable  to the  Merger  and the other  transactions  contemplated
hereby, so that the Merger and the other transactions contemplated hereby may be
consummated  as promptly as  practicable  on the terms  contemplated  hereby and
thereby and shall otherwise act to eliminate or minimize the effects of any such
takeover  statute  on the  execution  and  delivery  of  this  Agreement  or the
consummation of the transactions contemplated hereby.

                                       26
<PAGE>
     5.11 Further  Assurances.  The proper  officers of the Company and Acquirer
shall take any reasonably  necessary actions if, at any time after the Effective
Time,  any further  action is reasonably  necessary to carry out the purposes of
this Agreement.

     5.12  Actions by  Principals  Pending the Closing.  Each of the  Principals
covenants and agrees that,  prior to the Effective  Time, he will not do or fail
to do or cause  any  Person  to do or fail to do any act  that  will  cause  the
Company to breach any of its representations and warranties set forth in Section
3.1 hereof.

                                   ARTICLE 6.

                              CONDITIONS PRECEDENT

     6.1  Conditions  to Each  Party's  Obligation  to Effect  the  Merger.  The
respective  obligations  of the  Company  and  Acquirer to effect the Merger are
subject to the  satisfaction  or waiver on or prior to the  Closing  Date of the
following conditions:

          (a)  Stockholder  Approval.   The  Company  shall  have  obtained  all
approvals  of holders of shares of capital  stock of the  Company  necessary  to
approve this Agreement and all the transactions  contemplated hereby,  including
the Merger, under the DGCL.

          (b) No Injunctions or Restrains,  Illegality. No temporary restraining
order,  preliminary or permanent  injunction or other order issued by a court or
other Governmental Entity of competent  jurisdiction shall be in effect and have
the effect of making the Merger illegal or otherwise prohibiting consummation of
the Merger;  provided,  however, the party invoking this condition shall use its
reasonable  best  efforts  to have any such  order or  injunction  vacated.  The
provisions  of this  Section  6.1(b)  shall not be  available to any party whose
failure to fulfill its  obligations  pursuant to Section 5.3 shall have been the
cause of, or shall have resulted in, such order or injunction.

     6.2  Conditions  to the  Obligation  of Acquirer  to Effect the Merger.  In

the  Closing  Date,   except  to  the  extent  (i)  any   inaccuracies  in  such

earlier date. Acquirer shall have received an officer's  certificate executed on
behalf of the Company to such effect,  provided that such a signatory  shall not
have any personal liability in connection therewith, and provided, further, that
notwithstanding  the  foregoing,  Acquirer  will remain  obligated to effect the

their covenants set forth in Section 5.12 hereof.

          (b) Performance of Obligations  and Covenants.  The Company shall have

except  where the  failure  to so  perform  or comply  would not have a Material
Adverse  Effect on the  Company or would not  prevent  the  consummation  of the
Merger  by  the  Outside  Date.   Acquirer  shall  have  received  an  officer's
certificate executed on behalf of the Company to such effect, provided that such
a signatory shall not have any personal liability in connection  therewith,  and
provided,  further,  that  notwithstanding  the foregoing,  Acquirer will remain
obligated to effect the Merger  despite such breach by the Company to the extent
that the circumstances that resulted in such breach also resulted in a breach by
the  Principals of their  representations  and  warranties  set forth in Section
3.2(j) hereof, or their covenants set forth in Section 5.12 hereof.

          (c)  Financing.  The  funding of the  financing  under the  Definitive

of Acquirer and the  Principals  set forth in this  Agreement  shall be true and
correct as of the date of this  Agreement  and as of the Closing  Date as though
made on and as of the Closing Date, except to the extent (i) any inaccuracies in
such representations or warranties,  individually or in the aggregate, would not
have a Material Adverse Effect on Acquirer  (provided that,  solely for purposes
of this  Section  6.3(a),  any  representation  or  warranty  of Acquirer or the
Principals that is qualified by materiality or Material  Adverse Effect shall be
read as if such language were not present) or would not prevent the consummation
of the Merger by the Outside Date, or (ii) such  representations  and warranties
speak as of an earlier  date.  The  Company  shall have  received  an  officer's
certificate  executed on behalf of Acquirer  and a  certificate  executed by the

                                       28
<PAGE>
          (b)  Performance  of  Obligations  and  Covenants.  Acquirer  and  the
Principals  shall  have  performed  or  complied  with all of  their  respective
obligations and covenants  required to be performed by them under this Agreement
at or prior to the  Closing  Date,  except  where the  failure  to so perform or
comply would not have a Material Adverse Effect on Acquirer or would not prevent
the  consummation  of the Merger by the Outside  Date.  The  Company  shall have
received  an  officer's  certificate  executed  on  behalf  of  Acquirer  and  a
certificate executed by the Principals to such effect.

part of any party hereto in exercising any right,  power or privilege  hereunder

     8.5 Entire Agreement; No Third Party Beneficiaries.

          (a)  This  Agreement  and the  other  agreements  referred  to  herein
constitute  the  entire   agreement  and  supersede  all  prior  agreements  and
understandings,  both  written and oral,  among the parties  with respect to the
subject matter hereof.

          (b) This  Agreement  is not  intended  to nor shall  anything  in this

benefit or remedy of any nature whatsoever under or by reason of this Agreement,
other than Section 5.8.

     8.6  Governing  Law.  THIS  AGREEMENT  SHALL BE GOVERNED  AND  CONSTRUED IN
ACCORDANCE  WITH THE LAWS OF THE STATE OF  ARIZONA,  WITHOUT  REGARD TO THE LAWS
THAT MIGHT BE APPLICABLE UNDER CONFLICTS OF LAWS PRINCIPLES.

     8.7 Waiver of Jury  Trial.  EACH OF THE  PARTIES  HERETO  ACKNOWLEDGES  AND
AGREES THAT ANY  CONTROVERSY  WHICH MAY ARISE UNDER THIS  AGREEMENT IS LIKELY TO
INVOLVE  COMPLICATED AND DIFFICULT ISSUES,  AND THEREFORE EACH SUCH PARTY HEREBY
IRREVOCABLY AND UNCONDITIONALLY  WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY LEGAL  ACTION OR  PROCEEDING  DIRECTLY  OR  INDIRECTLY
ARISING OUT OF OR RELATING TO THIS  AGREEMENT OR THE  TRANSACTIONS  CONTEMPLATED
HEREBY AND FOR ANY COUNTERCLAIM  THEREIN.  EACH PARTY  ACKNOWLEDGES  THAT (i) NO
REPRESENTATIVE  OF SUCH PARTY HAS BEEN AUTHORIZED BY SUCH PARTY TO REPRESENT OR,

SUCH PARTY WOULD NOT, IN THE EVENT OF  LITIGATION  SEEK TO ENFORCE THE FOREGOING
WAIVER,  (ii) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS
WAIVER, (iii) EACH PARTY MAKES THIS WAIVER VOLUNTARILY,  AND (iv) EACH PARTY HAS
BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE PROVISIONS
OF THIS SECTION 8.7.

     8.8  Severability.  If any term or other  provision  of this  Agreement  is
invalid, illegal or incapable of being enforced by any law or public policy, all
other terms and provisions of this Agreement shall  nevertheless  remain in full
force and effect so long as the economic or legal substance of the  transactions
contemplated  hereby is not  affected  in any manner  materially  adverse to any
party.  Upon such  determination  that any term or other  provision  is invalid,
illegal or incapable of being  enforced,  the parties hereto shall  negotiate in
good faith to modify this  Agreement so as to effect the original  intent of the
parties  as  closely  as  possible  in an  acceptable  manner in order  that the
transactions  contemplated hereby are consummated as originally  contemplated to
the greatest  extent  possible.  Any provision of this Agreement held invalid or

                                       35
<PAGE>
unenforceable  only in part, degree or in certain  jurisdictions  will remain in
full force and effect to the extent not held  invalid or  unenforceable.  To the
extent permitted by applicable law, each party waives any provision of law which
renders any provision of this Agreement invalid, illegal or unenforceable in any
respect.

     8.9 Assignment.  Neither this Agreement nor any of the rights, interests or
obligations  hereunder shall be assigned by any of the parties hereto,  in whole
or in part (whether by operation of law or otherwise), without the prior written
consent of the other party, and any attempt to make any such assignment  without
such consent  shall be null and void.  Subject to the preceding  sentence,  this
Agreement  will be binding upon,  inure to the benefit of and be  enforceable by
the parties and their respective successors and assigns.

     8.10 Enforcement.  The parties agree that irreparable damage would occur in
the event that any of the  provisions  of this  Agreement  were not performed in
accordance  with  their  specific  terms  or  were  otherwise  breached.  It  is
accordingly agreed that the parties shall be entitled to specific performance of
the terms and provisions of this Agreement (without  requirement to post a bond,
if applicable),  this being in addition to any other remedy to which the parties

                             FAIRNESS OPINION LETTER

                OPINION OF PEACOCK, HISLOP, STALEY & GIVEN, INC.

March 28, 2000


Special Committee of the Board of Directors
Board of Directors
Arizona Instrument Corporation
1912 West 4th Street
Tempe, AZ  85281

Gentlemen:

We understand that Arizona Instrument  Corporation (the "Company" or "AZIC") and
AZI LLC ("Newco.")  formed on March 7, 2000, and owned by George G. Hays, Harold
D.  Schwartz  and G.  James  Hays  (the  "Acquiror")  propose  to enter  into an
Agreement  and Plan of Merger (the  "Agreement")  which  provides for the merger
(the "Merger") of the Company with and into Newco.  Under the terms set forth in
the Agreement at the effective time of the Merger (the "Effective  Time"),  each
share of common stock,  $0.01 par value, of the Company ("Company Stock") issued
and outstanding  immediately  prior to the Effective Time, other than any shares
of Company Stock held in the treasury of the Company and shares of Company Stock
owned by the Acquiror, if any, which will be canceled pursuant to the Agreement,
will be  converted  into the right to receive an amount  equal to $5.00 in cash,
without interest (the "Merger  Consideration").  The terms and conditions of the
Merger are set out more fully in the Agreement.  We note that the Merger has not
yet been consummated and that our opinion is as of the date hereof.

You have  requested  our opinion as to the fairness of the Merger  Consideration
from a financial  point of view to the  holders of Company  Stock other than the
Acquiror,   Mr.  Hays  and  their  respective   affiliates  (the   "Unaffiliated
Shareholders").

Peacock,  Hislop,  Staley  &  Given,  Inc.  ("Peacock  Hislop"),  as part of its
investment  banking  business,  is engaged in the  evaluation of businesses  and
their  securities  in  connection  with  mergers  and  acquisitions,  negotiated
underwritings,   competitive  bidding,  secondary  distribution  of  listed  and
unlisted securities, private placements and valuations for estate, corporate and
other purposes.

In  conducting  our  investigation  and  analysis and in arriving at our opinion
herein,  we have reviewed such information and taken into account such financial
and economic factors as we have deemed relevant under the circumstances. In that
context, we have among other things: (i) reviewed certain internal  information,
primarily financial in nature, including projections concerning the business and
operations of the Company furnished to us for purposes of our analysis,  as well
as publicly available information,  including, but not limited to, the Company's
recent filings with the Securities  and Exchange  Commission;  (ii) reviewed the
draft Agreement in the form presented to the Company's  Special Committee of the
Board of  Directors;  (iii)  compared the  historical  market prices and trading
activity  of AZIC  Common  Stock  with those of certain  other  publicly  traded
companies we deemed relevant; (iv) compared the financial position and operating
results of the Company with those of other publicly  traded  companies we deemed
relevant;  (v)  compared  the  proposed  financial  terms of the Merger with the
financial  terms of certain  other  business  combination  transactions  that we
deemed  relevant;  and (vi)  prepared  a  discounted  cash flow  analysis  and a
leveraged  acquisition  analysis of the Company.  We have held  discussions with
members of the Company's senior management  concerning the Company's  historical
and current  financial  condition and operating  results,  as well as the future
prospects of the Company.  We have also  considered  other  information  such as
financial studies and market reports, analyses and investigations and financial,
economic and market  criteria  which we deemed  relevant for the  preparation of
this opinion.

In arriving at our  opinion,  we have  assumed and relied upon the  accuracy and
completeness  of all of the  financial and other  information  that was publicly
available  or  provided  to us by or on behalf of the  Company and have not been
engaged to independently verify any such information. We have assumed, with your
consent, (i) that all material assets and liabilities  (contingent or otherwise,
known or unknown) of the  Company  are as set forth in the  Company's  financial
statements and/or have been disclosed to us, specifically pending litigation and
environmental  liabilities,  and (ii) that the  Merger  will be  consummated  in
accordance  with the terms of the  Agreement  without any  amendment  thereto or
waiver by the Company of any condition to their respective obligations.  We have
also  assumed  that  the  financial  forecasts  examined  by us were  reasonably
prepared  on  bases  reflecting  the best  available  estimates  and good  faith
judgements of the Company's  senior  management as to the future  performance of
the Company and that such forecasts  will be realized at the times  contemplated
therein.

Furthermore,  we have not undertaken  nor obtained an independent  evaluation or
appraisal of any of the assets or liabilities,  contingent or otherwise,  of the
Company,  nor have we made a physical inspection of the properties or facilities
of AZIC.  Our opinion  necessarily  is based upon  economic  monetary and market
conditions  as they exist and can be evaluated on the date hereof,  and does not
predict or take into account any changes which may occur, or information,  which
may become available, after the date hereof.

Our opinion has been  prepared  at the  request and for the  information  of the
Special  Committee of the Board of  Directors  of the Company,  and shall not be
used for any other  purpose or  disclosed  to any other party  without the prior
written consent of Peacock Hislop;  provided,  however,  that this letter may be
reproduced in full in the Proxy Statement- to be provided to the shareholders of
AZIC in  connection  with the Merger and may be filed  with the  Securities  and
Exchange  Commission in  connection  with the related  Transaction  Statement on
Schedule 13e-3.

The  Company's  Special  Committee  of  the  Board  of  Directors   conducted  a
solicitation process, which we took no part in, to attract the interest of third
parties in acquiring  all or any part of AZIC.  We have been  informed  that Mr.
Hays' offer was the only offer received that was deemed to be an acceptable firm
offer  by the  Special  Committee.  We have  not  been  asked  to,  and are not,
rendering an opinion as to the fairness of the solicitation process conducted by
the Special Committee.

This opinion  does not address the  relative  merits of the Merger and any other
potential  transactions  or  business  strategies  considered  by the  Company's
Special  Committee  of the  Board  of  Directors,  and  does  not  constitute  a
recommendation  to any shareholder of the Company as to how any such shareholder
should vote with respect to the Merger.  We have not been  requested to, and did
not: (i)  participate  in the  structuring  or negotiating of the Merger and the
Merger  Agreement;  or (ii)  solicit  third  party  indications  of  interest in
acquiring  all or any  part of  AZIC.  Peacock  Hislop  will  receive  a fee for
rendering  this  opinion.  At no time in the past,  have we provided  investment
banking services to the Company,  and we will earn no other fees,  contingent or
otherwise,  in connection with this Merger.  The Company has agreed to indemnify
us for certain liabilities that may arise out of the rendering of this opinion.

In the ordinary  course of our business,  we may,  from time to time,  trade the
securities  of the Company for our own account or the accounts of our  customers
and,  accordingly,  may  at  any  time  hold  long  or  short  positions  in its
securities.

Based upon and subject to the  foregoing,  we are of the opinion that, as of the
date hereof,  the Merger  Consideration is fair, from a financial point of view,
to the Unaffiliated Shareholders of AZIC.

Very truly yours,


PEACOCK, HISLOP, STALEY & GIVEN, INC.

               SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW
                         RELATING TO DISSENTERS' RIGHTS

     262 APPRAISAL RIGHTS.

     (a)  Any shareholder of a corporation of this State who holds shares of
          stock on the date of the making of a demand pursuant to subsection (d)
          of this section with respect to such shares, who continuously holds
          such shares through the effective date of the merger or consolidation,
          who has otherwise complied with subsection (d) of this section and who
          has neither voted in favor of the merger or consolidation nor
          consented thereto in writing pursuant to Section 228 of this title
          shall be entitled to an appraisal by the Court of Chancery of the fair
          value of the shareholder's shares of stock under the circumstances
          described in subsections (b) and (c) of this section. As used in this
          section, the word "shareholder" means a holder of record of stock in a
          stock corporation and also a member of record of a nonstock
          corporation; the words "stock" and "share" mean and include what is
          ordinarily meant by those words and also membership or membership
          interest of a member of a nonstock corporation; and the words
          "depository receipt" mean a receipt or other instrument issued by a
          depository representing an interest in one or more shares, or
          fractions thereof, solely of stock of a corporation, which stock is
          deposited with the depository.

     (b)  Appraisal rights shall be available for the shares of any class or
          series of stock of a constituent corporation in a merger or
          consolidation to be effected pursuant to Section 251 (other than a
          merger effected pursuant to Section 251(g) of this title), Section
          252, Section 254, Section 257, Section 258, Section 263 or Section 264
          of this title:

          (1)  Provided, however, that no appraisal rights under this section
               shall be available for the shares of any class or series of
               stock, which stock, or depository receipts in respect thereof, at
               the record date fixed to determine the shareholders entitled to
               receive notice of and to vote at the meeting of shareholders to
               act upon the agreement of merger or consolidation, were either
               (i) listed on a national securities exchange or designated as a
               national market system security on an interdealer quotation

               provided that no appraisal rights shall be available for any
               shares of stock of the constituent corporation surviving a merger
               if the merger did not require for its approval the vote of the
               shareholders of the surviving corporation as provided in
               subsection (f) of Section 251 of this title.

          (2)  Notwithstanding paragraph (1) of this subsection, appraisal
               rights under this section shall be available for the shares of
               any class or series of stock of a constituent corporation if the
               holders thereof are required by the terms of an agreement of
               merger or consolidation pursuant to Sections 251, 252, 254, 257,
               258, 263 and 264 of this title to accept for such stock anything
               except:

               a.   Shares of stock of the corporation surviving or resulting

               b.   Shares of stock of any other corporation, or depository
                    receipts in respect thereof, which shares of stock (or
                    depository receipts in respect thereof) or depository
                    receipts at the effective date of the merger or
                    consolidation will be either listed on a national securities
                    exchange or designated as a national market system security
                    on an interdealer quotation system by the National
                    Association of Securities Dealers, Inc. or held of record by
                    more than 2,000 holders;
<PAGE>
               c.   Cash in lieu of fractional shares or fractional depository
                    receipts described in the foregoing subparagraphs a. and b.
                    of this paragraph; or

               d.   Any combination of the shares of stock, depository receipts
                    and cash in lieu of fractional shares or fractional
                    depository receipts described in the foregoing subparagraphs
                    a., b. and c. of this paragraph.

          (3)  In the event all of the stock of a subsidiary Delaware
               corporation party to a merger effected under Section 253 of this
               title is not owned by the parent corporation immediately prior to
               the merger, appraisal rights shall be available for the shares of
               the subsidiary Delaware corporation.

     (c)  Any corporation may provide in its certificate of incorporation that
          appraisal rights under this section shall be available for the shares
          of any class or series of its stock as a result of an amendment to its
          certificate of incorporation, any merger or consolidation in which the
          corporation is a constituent corporation or the sale of all or
          substantially all of the assets of the corporation. If the certificate
          of incorporation contains such a provision, the procedures of this
          section, including those set forth in subsections (d) and (e) of this
          section, shall apply as nearly as is practicable.

     (d)  Appraisal rights shall be perfected as follows:

          (1)  If a proposed merger or consolidation for which appraisal rights
               are provided under this section is to be submitted for approval
               at a meeting of shareholders, the corporation, not less than 20
               days prior to the meeting, shall notify each of its shareholders
               who was such on the record date for such meeting with respect to
               shares for which appraisal rights are available pursuant to
               subsections (b) or (c) hereof that appraisal rights are available
               for any or all of the shares of the constituent corporations, and
               shall include in such notice a copy of this section. Each
               shareholder electing to demand the appraisal of such
               shareholder's shares shall deliver to the corporation, before the
               taking of the vote on the merger or consolidation, a written
               demand for appraisal of such shareholder's shares. Such demand
               will be sufficient if it reasonably informs the corporation of
               the identity of the shareholder and that the shareholder intends
               thereby to demand the appraisal of such shareholder's shares. A
               proxy or vote against the merger or consolidation shall not
               constitute such a demand. A shareholder electing to take such
               action must do so by a separate written demand as herein
               provided. Within 10 days after the effective date of such merger
               or consolidation, the surviving or resulting corporation shall
               notify each shareholder of each constituent corporation who has
               complied with this subsection and has not voted in favor of or
               consented to the merger or consolidation of the date that the
               merger or consolidation has become effective; or

          (2)  If the merger or consolidation was approved pursuant to Section
               228 or Section 253 of this title, each constituent corporation,
               either before the effective date of the merger or consolidation
               or within ten days thereafter, shall notify each of the holders
               of any class or series of stock of such constituent corporation
               who are entitled to appraisal rights of the approval of the
               merger or consolidation and that appraisal rights are available
               for any or all shares of such class or series of stock of such
               constituent corporation, and shall include in such notice a copy
               of this section; provided that, if the notice is given on or
               after the effective date of the merger or consolidation, such
               notice shall be given by the surviving or resulting corporation
               to all such holders of any class or series of stock of a
               constituent corporation that are entitled to appraisal rights.
               Such notice may, and, if given on or after the effective date of
               the merger or consolidation, shall, also notify such shareholders
               of the effective date of the merger or consolidation. Any
               shareholder entitled to appraisal rights may, within 20 days
               after the date of mailing of such notice, demand in writing from
               the surviving or resulting corporation the appraisal of such
               holder's shares. Such demand will be sufficient if it reasonably
               informs the corporation of the identity of the shareholder and
<PAGE>
               that the shareholder intends thereby to demand the appraisal of
               such holder's shares. If such notice did not notify shareholders
               of the effective date of the merger or consolidation, either (i)
               each such constituent corporation shall send a second notice
               before the effective date of the merger or consolidation
               notifying each of the holders of any class or series of stock of
               such constituent corporation that are entitled to appraisal
               rights of the effective date of the merger or consolidation or
               (ii) the surviving or resulting corporation shall send such a
               second notice to all such holders on or within 10 days after such
               effective date; provided, however, that if such second notice is
               sent more than 20 days following the sending of the first notice,
               such second notice need only be sent to each shareholder who is
               entitled to appraisal rights and who has demanded appraisal of
               such holder's shares in accordance with this subsection. An
               affidavit of the secretary or assistant secretary or of the
               transfer agent of the corporation that is required to give either
               notice that such notice has been given shall, in the absence of
               fraud, be prima facie evidence of the facts stated therein. For
               purposes of determining the shareholders entitled to receive
               either notice, each constituent corporation may fix, in advance,
               a record date that shall be not more than 10 days prior to the
               date the notice is given, provided, that if the notice is given
               on or after the effective date of the merger or consolidation,
               the record date shall be such effective date. If no record date
               is fixed and the notice is given prior to the effective date, the
               record date shall be the close of business on the day next
               preceding the day on which the notice is given.

     (e)  Within 120 days after the effective date of the merger or
          consolidation, the surviving or resulting corporation or any
          shareholder who has complied with subsections (a) and (d) hereof and
          who is otherwise entitled to appraisal rights, may file a petition in
          the Court of Chancery demanding a determination of the value of the
          stock of all such shareholders. Notwithstanding the foregoing, at any
          time within 60 days after the effective date of the merger or
          consolidation, any shareholder shall have the right to withdraw such
          shareholder's demand for appraisal and to accept the terms offered
          upon the merger or consolidation. Within 120 days after the effective
          date of the merger or consolidation, any shareholder who has complied
          with the requirements of subsections (a) and (d) hereof, upon written
          request, shall be entitled to receive from the corporation surviving
          the merger or resulting from the consolidation a statement setting
          forth the aggregate number of shares not voted in favor of the merger
          or consolidation and with respect to which demands for appraisal have
          been received and the aggregate number of holders of such shares. Such
          written statement shall be mailed to the shareholder within 10 days
          after such shareholder's written request for such a statement is
          received by the surviving or resulting corporation or within 10 days
          after expiration of the period for delivery of demands for appraisal
          under subsection (d) hereof, whichever is later.

     (f)  Upon the filing of any such petition by a shareholder, service of a
          copy thereof shall be made upon the surviving or resulting
          corporation, which shall within 20 days after such service file in the
          office of the Register in Chancery in which the petition was filed a
          duly verified list containing the names and addresses of all
          shareholders who have demanded payment for their shares and with whom
          agreements as to the value of their shares have not been reached by
          the surviving or resulting corporation. If the petition shall be filed
          by the surviving or resulting corporation, the petition shall be
          accompanied by such a duly verified list. The Register in Chancery, if
          so ordered by the Court, shall give notice of the time and place fixed
          for the hearing of such petition by registered or certified mail to
          the surviving or resulting corporation and to the shareholders shown
          on the list at the addresses therein stated. Such notice shall also be
          given by 1 or more publications at least 1 week before the day of the
          hearing, in a newspaper of general circulation published in the City
          of Wilmington, Delaware or such publication as the Court deems
          advisable. The forms of the notices by mail and by publication shall
          be approved by the Court, and the costs thereof shall be borne by the
          surviving or resulting corporation.

     (g)  At the hearing on such petition, the Court shall determine the
          shareholders who have complied with this section and who have become
          entitled to appraisal rights. The Court may require the shareholders
          who have demanded an appraisal for their shares and who hold stock
          represented by certificates to submit their certificates of stock to
          the Register in Chancery for notation thereon of the pendency of the
<PAGE>
          appraisal proceedings; and if any shareholder fails to comply with
          such direction, the Court may dismiss the proceedings as to such
          shareholder.

     (h)  After determining the shareholders entitled to an appraisal, the Court
          shall appraise the shares, determining their fair value exclusive of
          any element of value arising from the accomplishment or expectation of
          the merger or consolidation, together with a fair rate of interest, if
          any, to be paid upon the amount determined to be the fair value. In
          determining such fair value, the Court shall take into account all
          relevant factors. In determining the fair rate of interest, the Court
          may consider all relevant factors, including the rate of interest
          which the surviving or resulting corporation would have had to pay to
          borrow money during the pendency of the proceeding. Upon application
          by the surviving or resulting corporation or by any shareholder
          entitled to participate in the appraisal proceeding, the Court may, in
          its discretion, permit discovery or other pretrial proceedings and may
          proceed to trial upon the appraisal prior to the final determination
          of the shareholder entitled to an appraisal. Any shareholder whose
          name appears on the list filed by the surviving or resulting
          corporation pursuant to subsection (f) of this section and who has
          submitted such shareholder's certificates of stock to the Register in
          Chancery, if such is required, may participate fully in all
          proceedings until it is finally determined that such shareholder is
          not entitled to appraisal rights under this section.

     (i)  The Court shall direct the payment of the fair value of the shares,
          together with interest, if any, by the surviving or resulting
          corporation to the shareholders entitled thereto. Interest may be
          simple or compound, as the Court may direct. Payment shall be so made
          to each such shareholder, in the case of holders of uncertificated
          stock forthwith, and the case of holders of shares represented by
          certificates upon the surrender to the corporation of the certificates
          representing such stock. The Court's decree may be enforced as other
          decrees in the Court of Chancery may be enforced, whether such
          surviving or resulting corporation be a corporation of this State or
          of any state.

     (j)  The costs of the proceeding may be determined by the Court and taxed
          upon the parties as the Court deems equitable in the circumstances.
          Upon application of a shareholder, the Court may order all or a
          portion of the expenses incurred by any shareholder in connection with
          the appraisal proceeding, including, without limitation, reasonable
          attorney's fees and the fees and expenses of experts, to be charged
          pro rata against the value of all the shares entitled to an appraisal.

     (k)  From and after the effective date of the merger or consolidation, no
          shareholder who has demanded appraisal rights as provided in
          subsection (d) of this section shall be entitled to vote such stock
          for any purpose or to receive payment of dividends or other
          distributions on the stock (except dividends or other distributions
          payable to shareholders of record at a date which is prior to the
          effective date of the merger or consolidation); provided, however,
          that if no petition for an appraisal shall be filed within the time
          provided in subsection (e) of this section, or if such shareholder
          shall deliver to the surviving or resulting corporation a written
          withdrawal of such shareholder's demand for an appraisal and an
          acceptance of the merger or consolidation, either within 60 days after
          the effective date of the merger or consolidation as provided in
          subsection (e) of this section or thereafter with the written approval
          of the corporation, then the right of such shareholder to an appraisal
          shall cease. Notwithstanding the foregoing, no appraisal proceeding in
          the Court of Chancery shall be dismissed as to any shareholder without
          the approval of the Court, and such approval may be conditioned upon
          such terms as the Court deems just.

     (l)  The shares of the surviving or resulting corporation to which the
          shares of such objecting shareholders would have been converted had
          they assented to the merger or consolidation shall have the status of
          authorized and unissued shares of the surviving or resulting
          corporation.

                                     PART I

ITEM 1. DESCRIPTION OF BUSINESS

GENERAL

     Arizona   Instrument   Corporation   designs  and  manufactures   precision
instruments  used in  quality  control,  industrial  control  and  environmental
monitoring  applications.  AZI  completed its initial  public stock  offering on
September 22, 1983, as Computrac Instruments,  Inc. Later that year, the Company
changed its name to Quintel  Corporation.  In March 1987, to reflect new product
offerings, the Company was renamed Arizona Instrument Corporation.

     AZI's  initial  product  was the  Computrac  moisture  analyzer  for use in
process  control  industries,  but the Company has expanded  into other  product
areas. In December 1986, AZI acquired Jerome Instrument Corporation  ("Jerome"),
a manufacturer of mercury and hydrogen  sulfide gas analyzers.  In January 1988,
AZI completed the acquisition of certain assets from Genelco,  Inc.  ("Genelco")
including  the  Soil  Sentry  line of  underground  storage  tank  ("UST")  leak
detection  systems.  In June 1994,  the  Company  introduced  the  ENCOMPASS(TM)
product,  its next generation of fuel  management and leak detection  compliance
systems.  The Company sold the  ENCOMPASS  product  line on April 30,  1999.  In
September  1992, the Company  acquired  Horizon  Engineering  and Testing,  Inc.
("Horizon"),  as an AZI wholly-owned subsidiary, that specialized in testing and
engineering  services for USTs; the Company  discontinued  Horizon's  operations
during 1997.

COMPUTRAC PRODUCT LINE

     Products - AZI was founded on the Computrac line of moisture analyzers. The
Computrac  moisture analyzers simplify and automate a tedious industrial quality
control  procedure.  Typically,  a sample material is weighed,  then dried in an
oven for several  hours to drive off  moisture.  The sample is weighed again and
the  initial  moisture  content of the sample is  computed  based on the loss of
water weight. Computrac instruments house a heating chamber to dry the sample, a
precision balance to measure sample weight change and a microprocessor that uses
an algorithm to quickly extrapolate moisture content based on the rate of weight
loss. This technology is named the "loss on drying" or LOD technique.
<PAGE>
     Computrac instruments are rugged enough to be used on the factory floor for
quick batch analysis and accurate enough for precise laboratory testing. They do
not require a trained  technician for operation.  Thus,  they can save customers
both time and money.

     In 1994, the Company  completed  development of the Computrac  MAX-2000 and
MAX-1000  moisture  analyzers.  The MAX-2000  uses digital  technology to detect
moisture  levels  accurately  down to .005% in as  little  as two  minutes.  The
MAX-2000 is programmable from an easy-to-use  front panel menu system,  allowing
the user to store test parameters for 30 different sample materials. It features
a real-time front panel display of moisture  values,  the elapsing test time and
drying-curve graph, a statistical software package, and the ability to send test
results to a PC or printer.

     In December 1995, the Company  announced that it completed proof of concept
of its new  line of  Computrac  3000  moisture  analyzers  with  Alpha  and Beta
production  units  completed  in  1996.  The  Computrac  3000,  targeted  at the
worldwide  titration  market,  requires no toxic reagents,  is simple to use and
maintain, and offers excellent correlation and repeatability. The Computrac 3000
was  released  for  sale to  customers  during  1997,  and in 1999  the  Company
announced  the Computrac  4000,  an instrument  designed to measure the moisture
content of edible oils, lubricating and cooling oils, and heavy fuels.

     The MAX-500  was  introduced  in 1996 as a lower  priced,  reduced  feature
version of the MAX-1000 and  MAX-2000.  The MAX-500 is for  customers who do not
need  all  the  features  or the  resolution  of the  other  Computrac  moisture
analyzers.

     Markets and Applications - The markets for Computrac instruments tend to be
niche applications in various industries.  Three primary industries have yielded
the Company's historical sales: Foods - measuring the moisture content of cookie
dough,  cigarette  tobacco,  pasta  and  numerous  other raw and  finished  food
products;  Chemicals  -  measuring  moisture  and total  solids  content of such
chemical products as adhesives,  coatings,  and paints; and Plastics - measuring
the water  content of resins used in molding or  extrusion.  Other  applications
include pharmaceutical production and forestry management.

JEROME PRODUCT LINE

     Products - The first  Jerome  product was  developed  in 1976 as a portable
mercury detector for mining applications. The initial "mercury in soil" detector
spawned a line of hand-held, battery powered, field portable instruments capable
of detecting mercury vapor and hydrogen sulfide in minute quantities.

     The Jerome 431-X mercury vapor analyzer ("Jerome Mercury Analyzer") quickly
and  accurately  quantifies  low levels of mercury  in ambient  air for  on-site
environmental  testing,  clean-up and analysis.  Using the  Company's  gold-film
sensing technology,  the unit can be carried to sources of mercury, and displays
results in seconds with the push of a button. After spill clean-up, the analyzer
can be used to verify that no hazardous residue remains.

     The Jerome 631-X hydrogen sulfide analyzer ("Jerome H2S Analyzer")  detects
and measures low levels of ambient hydrogen sulfide ("H2S"). Using the Company's
gold-film sensing  technology,  the hand-held  instrument quickly quantifies H2S
levels  down  to   parts-per-billion,   allowing  corrective  action  to  reduce
complaints that arise at noxious-odor levels. The simple-to-operate, push button
unit is easily  carried to sources of H2S where it  monitors  gas levels to meet
air quality standards.

     Markets and Applications - Mercury - The market for Jerome Mercury Analyzer
comprises customers in three major groups:

     Industrial  Hygiene - These  applications  involve  workplace  screening to
ensure  employees are not  subjected to  unacceptable  mercury risk.  The United
States Occupational Safety and Health Administration requires industries such as
battery  and caustic  soda  manufacturers,  thermometer  and  fluorescent  light
manufacturers, hospitals and laboratories to monitor for mercury.

                                       2
<PAGE>
     Industrial  Process  Quality  Control - These customers test for mercury in
products where even trace amounts can have toxic  effects,  such as the confined
environments  of  submarines,  engine  rooms  or  spacecraft.  Suppliers  to the
National  Aeronautics  and Space  Administration  and the United States Navy are
required  under   procurement   contracts  to  certify  that  certain  equipment
components are mercury free.

     Mercury Dental Amalgam  Screening - Mercury and silver dental amalgams have
become the  subject of intense  scrutiny  and  controversy.  The Jerome  Mercury
Analyzer has been used in research on this topic,  and the Company believes that
it is  recognized  in the dental and medical  professions  as the only  portable
instrument that provides accurate mercury vapor readings at the required levels.

     Markets  and  Applications  - Hydrogen  Sulfide - The  Jerome H2S  Analyzer
allows  industries  to monitor H2S in low parts per billion  levels for odor and
corrosion control.

     Odor Control - Jerome H2S Analyzers  effectively  quantify the noxious odor
of H2S  given  off  from  industrial  processes  in  order  to  manage  customer
complaints or potential  litigation.  The most common  market is the  wastewater
treatment industry.

     Corrosion  Control - Searching for and quantifying the presence of H2S near
costly industrial  equipment is critical since H2S and its byproducts are highly
corrosive.  Industries  utilizing the Jerome H2S Analyzer for corrosion  control
include  wastewater  treatment,  oil  and  gas  refining,  and  pulp  and  paper
processing.

ENCOMPASS(TM) AND SOIL SENTRY PRODUCT LINE

     Products - ENCOMPASS  and the Soil Sentry  line of UST  monitoring  systems
include  various  products that allow UST  operators  with diverse site needs to
automate  fuel  management  and comply  with  federal  and local leak  detection
regulations.

     In June 1994,  the Company  introduced  the ENCOMPASS  product,  a personal
computer-based fuel inventory reporting and environmental compliance system that
utilizes on-site  personal  computers to manage fuel inventory and meet EPA leak
detection requirements.  The ENCOMPASS system was compatible with other business
software and runs in the computer's  background without  interrupting other site
activities.  In the  event  of an  alarm  condition,  the  system  automatically
notified the operator. The ENCOMPASS system ran in a Windows-based environment.

     Sales of the Company's  Encompass and Soil Sentry  products for 1998 failed
to meet  expectations.  The  Company  believes  the  slower  sales  were  due to
decisions  by many UST  operators  to seek less  expensive  methods  of  meeting
regulatory  requirements  such as annual tank  testing,  combined  with  monthly
inventory reconciliation or statistical inventory reconciliation. In response to
the declining  sales,  the Company sold certain  assets related to the Encompass
and Soil Sentry product lines to National  Environmental  Service, Co. ("NESCO")
pursuant to an Asset Purchase Agreement executed April 30, 1999.

HORIZON

     Services - Horizon was acquired in 1992 to facilitate  the  penetration  of
the UST market by the  Company's  Soil Sentry  products.  Horizon  provided tank
testing  services using a tracer testing system for USTs,  which was licensed to
Horizon by Tracer  Research Corp.  ("Tracer") of Tucson,  Arizona.  In 1997, the
Company discontinued Horizon's operations.

PRODUCT RELIABILITY AND QUALITY CONTROL

     The Company  believes  its  products  are highly  reliable.  The  Company's
products have built-in  self-test  features that are designed to insure that the
instrument is functioning  properly and will provide an accurate result.  If any
of the self-tests  indicate  abnormal  conditions,  the operator is alerted by a
light,  and a coded  display  indicates the type of  malfunction.  The Company's

                                       3
<PAGE>
products have one- and two-year parts and labor  warranties.  For the year ended
December 31, 1999, warranty expense approximated 2% of net sales.

     In  February   1996,   the  Company   achieved  ISO  9001  Quality   System
Certification.  This  certification  is  registered  through  SGS  International
Certification  Services,  Inc., an ANSI-RAB accredited  registrar.  The ISO 9001
certification  defines  models for quality  assurance in every phase of business
operations  including design,  development,  quality control,  customer service,
production,  installation  and service.  Certification to the worldwide ISO 9001
standard  establishes  that the Company  has in place  policies,  practices  and
procedures to provide  services using quality  management  systems in compliance
with International Organization of Standardization (ISO) model.

MANUFACTURING AND SOURCES OF SUPPLY

     The  majority  of the  Company's  manufacturing  costs  are  for  purchased
components. Certain of the components are then provided to outside companies for
subassembly,  with final assembly and testing performed by the Company. While in
some cases,  the Company relies on sole source  vendors,  secondary  vendors are
generally  available.  Raw materials and component parts are supplied by vendors
to the Company pursuant to specifications  set by AZI. The Company has initiated
a vendor  qualification  program,  and  believes  that,  if  necessary,  the raw
materials and  components  supplied by sole source  vendors could be supplied by
such other vendors without a material disruption of the manufacturing process.

MARKETING AND SALES; BACKLOG

     The Company's marketing and sales strategy is to identify major markets its
products can serve,  evaluate the sales  potential of each market  segment,  and
conduct  specialized  promotional  campaigns,  market by market, to elicit sales
inquiries from prospective  customers.  The majority of the Company's  promotion
budget  is  spent on trade  advertising,  public  relations  and  exhibiting  at
industry trade shows.

     Inquiries are processed through an in-house inquiry handling system.  Sales
representatives   are  trained  to  follow  up  on  inquiries  and  qualify  the
applicability of the Company's products to the prospect's need.

     Historically,  due to the relatively  short time period between  receipt of
customer orders and shipment of products,  the Company's  backlog has been quite
low. The dollar  amount of unfilled  orders at the  beginning of any quarter has
not exceeded 15% of sales for that quarter.

     The Company markets its instruments for export through its own sales force,
as well as through  foreign  distributors in Canada,  Europe,  the Far East, and
Latin America.

INDUSTRIES SERVED - CUSTOMERS

     The specific industries served domestically by each product are detailed in
the specific Markets and Applications sections presented earlier.

     Most  export  sales are to foreign  distributors.  The Company is unable to
determine which  industries are served by the export sales, but believes them to
be similar in pattern to domestic sales.  Export sales were approximately 18% of
total sales in 1999,  with no sales to any country  exceeding  10% of net sales.
(See Note 8 to the Consolidated Financial Statements)

     The Company's  business with United States government  agencies is effected
through  one  contract  with the  General  Services  Administration.  The Jerome
products are available for purchase by federal  agencies  through this contract.
The contract does not provide for renegotiation of profits,  except upon renewal
of such contract or termination at the election of the government.  The contract
for the Jerome product line was renewed without substantial  modifications.  The
Company's  products  and services are not subject to  government  approval.  The
Company is not aware of any pending government regulations that would materially
affect its business.

COMPETITION

     Computrac - A number of companies have products that compete with Computrac
moisture  analyzers.  For  applications  where  very  low  moisture  levels  are
measured,  titrators provide the greatest  competition.  Many of these companies
operate both domestically and internationally.

     Jerome - There is no  significant  competition  for Jerome in  applications
where low levels of hydrogen  sulfide  gas or mercury  vapor need to be measured
with a hand-held  ambient air  analyzer.  When a less  sensitive  instrument  is
needed, the level of competition increases.

RESEARCH AND DEVELOPMENT

     The Company believes that the development of new products, enhancements for
existing  products,  and the  development of new  applications  for its existing
products  are  critical  to  its  success.  Research  and  development  expenses
decreased  34.6%  in 1999  compared  to  1998.  Expenditures  for  research  and
development  for the years ended December 31, 1999, 1998 and 1997 were $866,985,
$1,324,640, and $984,628,  respectively. This represented 9.6% of sales in 1999,
9.6% of sales in 1998, and 6.5% of sales in 1997. The Company intends to develop
additional  instrumentation  products and services through OEM relationships and
the  acquisition  of  related  product  lines or  instrument  companies.  During
February  of  1999,  Mr.  Walfred   Raisanen   resigned  as  Vice  President  of
Engineering.   The  Company  then   reorganized  its  Research  and  Development
departments.

PATENTS, LICENSES AND TRADEMARKS

     The  Company  owns three  patents  directed  to  aspects  of its  Computrac
product,  and two domestic and five foreign  patents  directed to aspects of its
Jerome  product.  The Company does not believe  that  patents are a  significant
long-term competitive factor in these businesses and intends to rely more on its
on-going research and development,  engineering and customer service to maintain
a  long-term  competitive  advantage  in the market  place.  The Company has not
granted  licenses  under  any of its  patents  and  such  patents  have not been
challenged  or upheld in court.  There can be no assurance  that the validity of
the patents will be upheld if challenged.

EMPLOYEES

     As of December 31, 1999, the Company had a total of 60 full time employees.
The Company provides ongoing training to its technical and sales personnel. None
of the Company's employees are represented by a union.  Management believes that
relations between the Company and its employees are excellent.

     Effective  March 18, 1999,  the  Company's  Board of Directors  amended its
employment  agreement with George G. Hays. Pursuant to that amendment,  the term
of the  employment  contract was  extended to March 31,  2001.  The contract was
amended  further to grant Mr. Hays his salary for the full term of the  contract
in the event the Company  sells all or  substantially  all of its assets or if a
change in control of the Company occurs.

MATERIAL PURCHASES, SALES AND STOCK CONVERSIONS

     The Company's  shareholders approved a 1 for 5 reverse split of outstanding
common  stock at a special  meeting on February 5, 1999.  The Board of Directors
approved the transaction on February 8, 1999.

     In April 1999,  the Company  executed a letter of intent with NESCO to sell
the  assets of AZI's  Encompass  and Soil  Sentry  product  lines to NESCO.  The
parties  executed an Asset  Purchase  Agreement on April 30,  1999,  pursuant to
which NESCO agreed to pay the Company  $1,000,000 in exchange for the marketing,
licensing, distributing,  developing,  manufacturing,  service and operations of
Encompass and Soil Sentry, and the monitoring  services of their users.  Because
of this  sale,  the  Company  has been able to  redirect  its  attention  to its
historic core businesses of moisture analysis and toxic gas analysis.

                                       5
<PAGE>
     On  February  1, 2000,  the  Company  entered  into a letter of intent with
George G. Hays, its President and Chief Executive Officer, Harold D. Schwartz, a
member of the  Company's  Board of Directors,  and G. James Hays,  the father of
George G. Hays, for the acquisition of all of AZI's outstanding shares not owned
by them. This  transaction  was approved by a special  committee of the Board of
Directors,  which was formed in August  1999,  and is subject to approval by the
Company's shareholders, satisfactory completion of a due diligence investigation
by Mr.  Hays,  receipt  of a  fairness  opinion,  and  certain  other  customary
conditions.  The Company  anticipates that a shareholder vote and the closing of
the  transaction  (if  approved by the  shareholders)  will likely  occur in the
second quarter of 2000.

ITEM 2. DESCRIPTION OF PROPERTY

     As the result of a roof collapse at the Company's headquarters,  located at
4114 East Wood Street, Tempe, Arizona, in July 1999, during a monsoon storm, the
Company  moved  its   facilities   and  entered  into  a  lease   agreement  for
approximately  20,000  square  feet at 1912  West 4th  Street,  Tempe,  Arizona.
Although the  disruption in  operations  caused by the roof collapse and move to
the new facilities  adversely affected the Company's net sales, the Company does
not consider  the effect to be material.  All  administration,  sales,  customer
service,  engineering  and  manufacturing  for the  Company are in the new Tempe
facility.  The lease on the new building  expires in September 2004. The Company
believes that its facilities are modern,  well-maintained and sufficient for its
current needs.

ITEM 3. LEGAL PROCEEDINGS

     On March 7, 1997,  the Company was served with a summons and first  amended
complaint  which was filed in the United States  District Court for the District
of Idaho on February 28, 1997 by United Co-op,  Inc. and Idaho  Petroleum  Clean
Water Trust Fund.  The  complaint  alleges  breach of  contractual  promises and
breach of warranties  in a commercial  transaction  for tank and line  tightness
services. The Company agreed to a settlement of this matter in March 1999.

     In February 1999, the Company  received a letter from BP Oil Company ("BP")
demanding the return of approximately  $1.9 million previously paid by BP to the
Company in prior years for the purchase of  Encompass  tank gauge  systems,  the
removal of Encompass  systems  from BP sites,  and for the  cancellation  of any
outstanding invoices from AZI. This suit was settled for $35,000 in July 1999.

     In February 2000,  the Company  received a demand in the amount of $100,000
from Maxey Energy Systems for alleged  difficulties with  Encompass/Soil  Sentry
software and hardware. The Company is investigating the claim.

     From time to time,  the Company is involved in routine  litigation  that is
incidental to its business.  The Company is not currently  involved in any other
legal  proceedings,  the  result  of which the  Company  believes  would  have a
material adverse effect upon the Company.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     The Company did not submit any matters to a vote of security holders in the
fourth quarter of 1999.

ITEM 5. MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

     The  Company's  Common Stock  trades on the Nasdaq Small Cap Market.  As of
March 22,  2000,  there were  approximately  311  shareholders  of record of the
Company's common stock, its only class of common equity.  The high and low sales
prices set forth below are derived from information provided by The Nasdaq Stock
Market.

     The Company has never paid a cash dividend and currently  intends to retain
all earnings for use in its business.  The  declaration and payment of dividends
in the  future  will be  determined  by the  Board  of  Directors  in  light  of
conditions then existing, including the Company's earnings, financial condition,
capital  requirements  and other factors.  Dividends are also  restricted by the
Company's lines of credit  agreements with the Company's bank. See "Management's
Discussion and Analysis or Plan of Operation."

ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

Except for the historical  information  contained herein, the discussion in this
Form 10-KSB contains certain  forward-looking  statements  within the meaning of
the Private  Securities  Litigation  Reform Act of 1995, and the Company intends
that such  forward-looking  statements  be subject to the safe  harbors  created
thereby.   The   forward-looking   statements   include   statements   regarding
management's  anticipation of the Company's future market position,  development
of additional products,  product introduction and delivery dates, reliability of
products, adequate sources of supplies,  acquisition of related product lines or
companies positive responses to new developments,  and availability and terms of
credit.  The  forward-looking  statements  included  herein are based on current
expectations  that  involve  a  number  of  risks  and  uncertainties,   and  on
assumptions that involve  judgments with respect to, among other things,  future
economic,  competitive and market conditions,  research and development results,
product introduction and delivery schedules,  raw materials,  market conditions,
stability of the regulatory environment,  and future business decisions,  all of
which are difficult or impossible  to predict  accurately  and many of which are
beyond the  control of the  Company.  Although  the  Company  believes  that the
assumptions underlying the forward-looking  statements, many of which are beyond
the control of the Company,  are reasonable,  any of the assumptions could prove
inaccurate  and,  therefore,   there  can  be  no  assurance  that  the  results
contemplated in forward-looking information will be realized.  Important factors
which may cause actual results to differ  materially from those  contemplated or
implied by such forward-looking  statements are discussed in more detail in this
form  10-KSB.  In  light  of  the  significant  uncertainties  inherent  in  the
forward-looking  information  included herein, the inclusion of such information
should not be regarded as a  representation  by the Company or any other  person
that the objectives or plans of the Company will be achieved.

1999 vs. 1998

     Net sales  decreased  by  $4,684,476  or 34.1% to  $9,052,505  in 1999 from
$13,736,981 in 1998.  Sales  decreased  primarily due to reduced  Encompass/Soil
Sentry system and  installation  revenues which resulted from the disposition of
the Soil Sentry/Encompass  product line in April, 1999, and to a lesser extent a
decline in sales of Jerome instruments.

     Cost of goods sold  decreased by  $3,144,865 or 49.2% to $3,252,610 in 1999
from  $6,397,475  in 1998.  The  decrease in Cost of goods sold was due to lower
Encompass/Soil  Sentry system and  installation  costs which resulted from lower
sales.  Cost of goods sold was 35.9% of sales in 1999 compared to 46.6% of sales
in 1998. Gross margin improved  primarily to the change in product mix resulting
from the sale of the  Encompass/Soil  Sentry product line and to a lesser extent
the better utilization of manufacturing resources.

     Operating  expenses in 1999  decreased by $1,704,876 or 24.9% to $5,132,775
from $6,837,651 in 1998. The decrease in operating expenses for 1999 compared to
1998 was a result of  decreased  personnel  expenses  and other  expenses  which
resulted from the sale of the Encompass/Soil Sentry product line and to a lesser
extent the Company's  continuing cost reduction effort.  Operating expenses were
56.7%  of  sales  in 1999,  as  compared  to  49.7% of sales in 1998.  Marketing

                                       8
<PAGE>
expenses  decreased by $841,838 or 26.8% to $2,303,230  from $3,145,068 in 1999.
Marketing   expenses   decreased   primarily   due  to  the  sale  of  the  Soil
Sentry/Encompass product line. Marketing expenses were 25.4% of sales in 1999 as
compared  to  22.9%  of  sales in  1998.  General  and  administrative  expenses
decreased by $253,162 or 14.6% to $1,479,004  from  $1,732,166 in 1998.  General
and  administrative  expenses  decreased  in 1999 due to  reductions  in capital
leases, property maintenance,  insurance and miscellaneous expenses. General and
administrative  expenses  were  16.3% of sales in 1999 as  compared  to 12.6% of
sales in 1998. Research and development  expenses decreased by $457,655 or 34.6%
in 1999 to $866,985  from  $1,324,640  in 1998.  The  decrease  in research  and
development  expenses was primarily due to a reduction in expenses for personnel
associated with the Encompass/Soil Sentry product line. Research and development
expenses  were  9.6% of  sales  in 1999 as  compared  to 9.6% of  sales in 1998.
Amortization  and  depreciation  expenses  decreased  by  $152,221  or  23.9% to
$483,556  from  $635,777  in 1998,  as the  Company  reduced  its  purchases  of
additional capital equipment.

     Other income (expense) in 1999 increased by $147,691 or 456.3% to income of
$115,321 as compared to loss of $32,370 in 1998.  Interest  income  increased by
$114,702 or 693.5% to $131,241 in 1999 from $16,539 in 1998,  due to better cash
management and the investment of the proceeds of the sale of the  Encompass/Soil
Sentry product line.  Interest  expense in 1999 decreased by $74,009 or 70.7% to
$30,651 from $104,660 in 1998, due to a decrease in average borrowings.

     As a result  income  before taxes  increased  by $312,956 to $782,441  from
$469,485 incurred in 1998.

     Income tax expense for 1999 was  $400,000 as compared to $344,000 for 1998.
The effective  income tax rates for 1999 and 1998 are greater than the statutory
federal and state rates due to nondeductible amortization and an increase in the
valuation allowance in 1998.

     As a result,  net income for 1999 was $382,441,  an increase of $256,956 or
204.8% from $125,485 in 1998.

LIQUIDITY AND CAPITAL RESOURCES

     Working  capital at December  31,  1999  increased  $1,046,563  or 25.8% to
$5,092,467 as compared to $4,045,904 of working capital at December 31 1998. The
current  ratio at December 31, 1999  increased to 5.6 from the current  ratio of
2.8 at December 31, 1998. The increase in working  capital and the current ratio
were primarily due to the Company's  positive cash  generated  from  operations,
which included the Encompass sale.

     At December 31, 1999,  accounts  receivable was  $1,649,030,  a decrease of
$1,263,600  from the  $2,912,630  accounts  receivable  as of December 31, 1998.
Receivables  decreased as a result of lower sales,  and an increase in allowance
for doubtful accounts.  The ratio of net sales to ending accounts receivable for
1999 was 5.5 as compared to 4.7 for 1998. This ratio increased  primarily due to
better  collection  efforts.  Inventory  at December  31, 1999 was  $688,236,  a
decrease of $958,568  from the  inventory of $1,646,804 as of December 31, 1998.
Inventory decreased due the sale of the Soil  Sentry/Encompass  product line and
to a lesser extent better inventory management.

     Cash and cash equivalents at December 31, 1999 were $3,471,429, an increase
of $2,372,583  from cash of  $1,098,846  at December 31, 1998.  Cash provided by
operating  activities  was  $1,886,079 as compared to cash provided by operating
activities of $2,199,610  for 1998.  Cash provided by operating  activities  was
used to repay debt and purchase capital equipment. The Company had no borrowings
from the line of credit at December  31,  1999,  as compared  to  borrowings  of
$300,000 as of December 31, 1998.

     As of December 31, 1999 the Company was in  compliance  with its  borrowing
agreement with Imperial Bank (the "Bank"). At December 31, 1999, the Company had
a line of credit with the Bank for $2,000,000  which was  collateralized  by the
Company's  assets.  At December 31, 1999, the Company had no  outstanding  debts
with this line of credit.  The failure to maintain  adequate  credit  facilities
would have a material adverse effect on the Company.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.   Summary of significant accounting policies:

     Description of business:

     Arizona  Instrument  Corporation  designs,  manufactures  and  markets  the
     Computrac   line  of   automated   microprocessor   controlled   analytical
     instruments used to measure the moisture  content of various  materials and
     the Jerome line of toxic gas detection instruments primarily used to detect
     mercury and hydrogen sulfide. The Company also had a line of computer-based
     fuel  management and compliance  leak detection  instruments for monitoring
     underground  storage tanks.  The Company sold the assets and rights to this
     product  line  during 1999 (see Note 10).  The Company  sells in the United
     States and also in international markets.

     Principles of consolidation:

     The consolidated financial  statements  include  the  accounts  of  Arizona
     Instrument Corporation and its wholly-owned subsidiaries (collectively, the
     "Company').  All material intercompany  profits,  transactions and balances
     have been eliminated upon consolidation.

     Concentrations of credit risk:

     The Company periodically holds cash deposits in excess of federally insured
     limits.

     Revenue recognition:

     Sales of instruments are recognized at the time shipments are made.

     Inventories:

     Inventories  are stated at the lower of cost or market using the  first-in,
     first-out method.

     Property, plant and equipment, amortization and depreciation:

     Property,  plant  and  equipment  are  recorded  at cost.  Depreciation  is
     provided by the straight-line method over the estimated useful lives of the
     various classes of assets.  Equipment and  furniture/fixtures are estimated
     to  have 5 and 7  year  lives,  respectively.  Leasehold  improvements  are
     amortized  over the shorter of the  estimated  useful life or the period of
     the lease.  Equipment under capital leases are generally amortized over the
     estimated lives of the related equipment.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


1.   Summary of significant accounting policies, continued:

     Goodwill and amortization:

     Goodwill is the cost of investments in purchased companies in excess of the
     fair value of net assets of the businesses acquired.  Goodwill is amortized
     on a straight-line basis over 20 years.

     Income per share:

     Basic  earnings  per share (EPS) is  computed as net income  divided by the
     weighted  average  number  of common  shares  outstanding  for the  period.
     Diluted EPS reflects the  potential  dilution  that could occur from common
     shares  issuable  through stock options,  warrants,  and other  convertible
     securities and includes shares issuable upon exercise of stock options when
     dilutive.

     Statements of cash flows:

     For purposes of the  consolidated  statements of cash flows,  cash and cash
     equivalents represent cash in bank and money market funds.

     Use of estimates:

     The preparation of  financial   statements  in  conformity  with  generally
     accepted  accounting  principles  requires management to make estimates and
     assumptions  that affect the reported amounts of assets and liabilities and
     disclosure  of  contingent  assets  and  liabilities,  at the  date  of the
     financial  statements  and the  reported  amounts of revenue  and  expenses
     during  the  reporting  period.  Actual  results  could  differ  from these
     estimates.

     Research and development:

     Research and development costs are charged to expense as incurred.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


 2.  Property, plant and equipment:

     Property,  plant  and  equipment  at  December  31,  1999  consists  of the
     following:

     Leasehold improvements                                           176,455
     Furniture, fixtures and equipment                              4,394,732
     Automobiles                                                       28,237
                                                                  -----------
                                                                    4,599,424
     Less accumulated depreciation
        and amortization                                           (3,805,453)
                                                                  -----------

                                                                  $   793,971
                                                                  ===========

 3.  Bank lines of credit:

     The Company has a revolving line of credit which provides for borrowings up
     to $2,000,000, based on eligible accounts receivable. The line of credit is
     collateralized by Company assets.  Borrowings  extended under the revolving
     line of credit  bear  interest  at prime  plus 1.5% (8.5% at  December  31,
     1999). The line of credit contains certain  covenants.  The Company did not
     have any  borrowings  against this line at December  31, 1999.  The line of
     credit expires June 2000.

4.   Estimated fair value of financial instruments:

     Statement of Financial Accounting Standard ("SFAS"). 107 "Disclosures About
     Fair Value of Financial  Instruments"  requires disclosure of the estimated
     fair value of certain financial instruments.  The Company has estimated the
     fair  value of its  financial  instruments  using  available  market  data.
     However,  considerable judgement is required in interpreting market data to
     develop estimates of fair value. The use of different market assumptions or
     methodologies  may have a material  effect on the estimates of fair values.
     The carrying  values of cash, and lines of credit  approximate  fair values
     due to the short-term maturities or market rates of interest.

5.   Shareholders' equity:

     In March 1985, the Company  adopted a Stock Option Plan ("SOP") under which
     the Company could, for a period of ten years,  grant options to purchase up
     to 50,000 shares of the Company's  common stock. SOP options may be granted
     to employees,  officers or directors of the Company or any subsidiary.  The
     exercise  price of options  must be at least the fair  market  value of the
     Company's  common  stock  on the  date of  grant  and the  options  must be
     exercised within 11 years from the date of grant.

5.   Shareholders' equity, continued:

     In April 1991, the Company  adopted the 1991 Stock Option Plan ("OP") under
     which the Company may,  for a period of ten years,  grant  incentive  stock
     options and  nonstatutory  stock options to purchase up to 90,000 shares of
     the  Company's  common stock.  In May, 1996 the Board of Directors  amended
     this Plan to increase the shares  reserved  for issuance by 60,000  shares.
     Additionally,  each year,  the number of shares of stock that may be issued
     is increased  automatically  by 1 % on January 1 if certain  conditions are
     met. Stock options may be granted to employees, directors and other persons
     whose  participation  is deemed to be in the Company's best  interest,  but
     only  employees may be granted  incentive  stock options.  Incentive  stock
     options  granted  under  the plan  have a  maximum  term of ten  years  and
     nonstatutory  options may have a maximum term of twenty years. The exercise
     price for an incentive  stock option must be at least the fair market value
     of the Company's  common stock on the date of grant. The exercise price for
     a  nonstatutory  option  may be any  amount  above  the  par  value  of the
     Company's  common stock determined in good faith. The current stock options
     granted have a vesting period ranging from six (6) months to five (5) years
     from the date of grant.

     The following is a summary of stock option activity:

                                                                       Weighted

5.   Shareholders' equity, continued:

     In January 1985, the Company  adopted an Employee Stock Purchase Plan which
     provides for the sale of up to 40,000  shares of common stock to qualifying
     employees of the Company. In May, 1996 and again in July 1999, the Board of
     Directors amended this Plan to increase the shares reserved for issuance by
     40,000 and 65,000 shares , respectively. The purchase price of the stock is
     85% of the lesser of the fair market  value at the  beginning or the end of
     the offering period,  January and July of each year. During the years ended
     December  31,  1999 and 1998 a total of 10,736 and 16,766  shares of common
     stock have been  purchased at average  prices of $3.20 and $3.60 per share,
     respectively.  As of December  31, 1999  approximately  65,000  shares were
     available under this plan.

     The estimated fair value of options granted during 1999 was $.99 per share,
     while the estimated fair value of options granted during 1998 was $1.50 per
     share. The Company applies  Accounting  Principles Board Opinion No. 25 and
     related  interpretations  in  accounting  for its stock option and purchase
     plans. Accordingly,  no compensation cost has been recognized for its stock
     option plans.  Had  compensation  cost for the Company's stock option plans
     been determined based on the fair value at the grant dates for awards under
     those plans consistent with the method of FASB Statement 123, the Company's
     net income and  earnings  per share for the years  ended  December 31 would
     have been as follows:

                                                          1999           1998

     The fair values of options  granted under the Company's  stock option plans
     were estimated on the date of grant using the Black-Scholes  option-pricing
     model with the following  weighted  average  assumptions  used: No dividend
     yield,  expected  volatility  of 58%,  risk free interest rate of 5.40% and
     expected lives of 3 years from vest date.

     On November 17, 1995, the Company entered into a loan agreement with a bank
     ("Bank").  The Bank  held a Note and a  warrant  to  purchase  up to 12,500
     unregistered  shares of the Company's  Common Stock at an exercise price of
     $10.40 per share.  The note was repaid in full during  1998.  The  warrants
     expire in November 2000.

     On February 8, 1999,  the Company  approved a  one-for-five  reverse  stock
     split of its issued and outstanding  common stock.  The reverse stock split
     has been retroactively reflected in the accompanying financial statements.

     statements of operations  differs from the amounts computed by applying the
     federal  statutory  income  tax  rates to income  before  income  taxes.  A
     reconciliation of the provision  (benefit) for income taxes and the amounts
     that would be computed using the statutory federal income tax rates for the
     years ended December 31, 1999 is set forth below:

6.   Income taxes, continued:

     Deferred  income  taxes  reflect  the  net  tax  effects  of (a)  temporary
     differences  between the  carrying  amounts of assets and  liabilities  for
     financial  reporting purposes and the amounts used for income tax purposes,
     and (b) tax  credit  carryforwards.  Management  estimates  that it is more
     likely than not that the Company will not use 100% of its future deductible
     amounts or tax credits.  As such,  management  has provided an allowance of
     $50,000 to offset its deferred tax assets.  The tax effects of  significant
     items  comprising  the  Company's net deferred tax asset as of December 31,
     1999 are as follows:

      Current deferred tax assets:
        Accrued expenses not currently deductible                     $ 173,000

     on an annual  basis.  Contribution  expense was  approximately  $15,000 and
     $3,500 for the years ended December 31, 1999 and 1998, respectively.

9.   Commitments and contingencies:

     Lease commitments:

     Certain  office  facilities  and  equipment  are  held  under  capital  and
     operating  leases.  These leases expire in periods through 2004 and include
     renewal  options.  Equipment  under capital leases included in property and
     equipment total $1,281,374 (less accumulated amortization of $1,275,751) at
     December 31, 1999.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


9.   Commitments and contingencies, continued:

     Litigation:

     From time to time,  the  Company  may become a  defendant  as the result of
     claims filed alleging breach of contractual  promises or warranties.  While
     the outcome of any such claim cannot be determined at this time, management
     of the Company  does not believe  that the  ultimate  disposition  of these
     claims will have a material effect on the financial  position or results of
     operations of the Company.

10.  Sale of product line:

     During 1999,  the Company  entered into an asset  purchase  agreement  with
     National  Environmental Services Company (NESCO), an unrelated party. NESCO
     purchased   certain   assets  of  the  Company  for  a  purchase  price  of
     approximately  $1,061,000.  The net  book  value  of the  assets  sold  was
     appoximately $1,036,000 resulting in a gain of approximately $25,000. Sales
     related to this product line were approximately $260,000 and $2,950,000 for
     the years ended December 31, 1999 and 1998, respectively.

11.  Subsequent event:

     On February 1, 2000, the Company  entered into a letter of intent  pursuant
     to which,  a company to be formed by the  President  of the  Company  and a
     member  of the  Company's  Board of  Directors,  would  acquire  all of the
     Company's  outstanding  shares  not  owned by them at a price of $5.00  per
     share in cash. The transaction is subject to authorization by the Company's
     shareholders.
