     (a) The Bidder has offered to purchase all outstanding Shares at a purchase
price of $14 per share, net to the seller in cash, without interest thereon, in
each case upon the terms and subject to the conditions set forth in the Offer to
Purchase dated July 12, 1999 of the Bidder ("Offer to Purchase") and related
Letter of Transmittal (which, together with any amendments or supplements
thereto, collectively constitute the Fauth Offer), copies of which were filed as
exhibits to the Schedule 14D-1. The Fauth Offer and withdrawal rights expire at
12:00 midnight, Eastern Time, on Wednesday, August 11, 1999, unless the Fauth
Offer


                                       2


is extended to a later date and time (the "Expiration Date"). Shares that are
tendered pursuant to the Fauth Offer may be withdrawn at any time prior to the
Expiration Date.

     The Fauth Offer is subject to fulfillment of certain conditions, including
the following:

1. Minimum Tender Condition. There being validly tendered and not withdrawn
prior to the Expiration Date that number of Shares, which when added to the
number of Shares owned by the Bidder and its affiliates, represents a majority
of the total number of outstanding Shares on a fully diluted basis on the date
of purchase. According to the Schedule 14D-1, approximately 5,012,506 Shares
must be tendered to satisfy this requirement.

2. Control Share Condition. The Bidder having determined in its sole discretion
that the Minnesota Control Share Acquisition Act is inapplicable to the Fauth
Offer or that it otherwise will not have the effect of denying voting rights to
the Shares acquired by the Bidder in the Fauth Offer.

3. Business Combination Condition. The Bidder being satisfied in its sole
discretion that a committee of disinterested directors of the Company has
approved the Fauth Offer in accordance with Section 302A.673 of the Minnesota
Statutes.

4. Election Condition. The election at the 1999 Annual Meeting of the Company's
stockholders (the "Annual Meeting") of Fauth's three director nominees.

5. Defensive Action Condition. The adoption of an amendment to the Company's
Articles of Incorporation at the Annual Meeting prohibiting the Company's Board
from adopting any defensive action with a primary purpose of preventing a change
of control of the Company unless such action is approved by the unanimous vote
of the Board.

6. Meeting Date Condition. The adoption of an amendment to the Company's bylaws
at the Annual Meeting providing that the annual meeting of stockholders for the
year 2000 shall be held not later than July 20, 2000, and the Board shall give
notice of the meeting on or before June 20, 2000.

Company's bylaws at the Annual Meeting prohibiting the Company's Board from

                                       3


9. Anti-Poison Pill/Dilution Condition. The adoption of an amendment to the
Company's Articles of Incorporation at the Annual Meeting prohibiting the
adoption of a shareholder rights plan (also known as a "poison pill") or the
issuance of the Company's securities that could increase the number of
outstanding Shares to more than 11,500,000 Shares without unanimous Board
approval during the period from the Annual Meeting until December 31, 2000.

10. Financing Condition. The Bidder being satisfied in its sole discretion that
it has obtained sufficient financing to consummate the Fauth Offer.

     At this time, the Bidder does not have a binding commitment to finance the
Fauth Offer. According to the Schedule 14D-1, the Bidder's parent corporation is
expected to contribute $30 million in cash to the Bidder which it will borrow
from Churchill Industries, Inc., an industrial holding company that is wholly
owned by Fauth. The loan is expected to be unsecured and guaranteed by Fauth, to
bear interest at the rate of 3.25% over the London Interbank Offer Rate and to
have a five-year term. The Schedule 14D-1 also states that BNY Capital Markets,
Inc. has provided the Bidder with a "highly confident letter" dated July 9,
1999, indicating that it was highly confident that it could obtain commitments
from lenders for a senior secured credit facility in an amount to fund a portion
of the payment obligations under the Fauth Offer. The July 9, 1999 letter of BNY
Capital Markets, Inc. expressly states that it is not making a binding
commitment to provide financing to the Bidder. In addition, any financing
provided by or through BNY Capital Markets, Inc. is subject to satisfaction (or
waiver) of numerous conditions, including but not limited to, the following:

o    no material adverse change in the financial condition, results of
     operations, business or prospects of the Company, the Bidder or Churchill
     Industries, Inc. and their subsidiaries since March 31, 1999, as determined
     in the sole discretion of BNY Capital Markets, Inc.;

o    no material adverse change in the market for high yield securities or
     capital markets in general, in the opinion of BNY Capital Markets, Inc.;

o    consolidated pro forma capitalization of the Company following the
     second-step merger proposed by Fauth, assuming consummation of the Fauth
     Offer and related permanent financings being acceptable to BNY Capital
     Markets, Inc.;

o    audited and unaudited historical financial statements (including unaudited
     pro forma financial statements) of the Company and its subsidiaries
     conforming to the requirements of the Securities and Exchange Commission
     being acceptable to BNY Capital Markets, Inc.;

o    BNY Capital Markets, Inc. not having discovered or otherwise becoming aware
     of any information not previously disclosed to it that it believes is
     inconsistent in a material and adverse manner with BNY Capital Markets,
     Inc.'s understanding


                                       4


     concerning the business, operations, property, condition (financial or
     otherwise) or prospects of the Company, the Bidder or Churchill Industries,
     Inc.;

o    terms, structure and arrangements regarding the financing and other
     financing for the Fauth Offer being acceptable to BNY Capital Markets,
     Inc.;

o    execution and delivery of definitive documentation relating to the
     financing acceptable to BNY Capital Markets, Inc.;

o    receipt of all appropriate regulatory approvals; and

o    no change or proposed change in laws that could be expected to adversely
     affect the economic consequences of the Fauth Offer.

     The Bidder states in the Schedule 14D-1 that it expects to finance the
additional amounts needed to consummate the Fauth Offer through additional
equity contributions to it or additional borrowings by the Bidder although no
specific arrangements have been made to obtain such additional financing.

     The Bidder will pay all charges and expenses of R.J. Steichen & Co., as
Dealer Manager, Firstar Bank of Minnesota, N.A., which is serving as Depository,
and Beacon Hill Partners, Inc., which is serving as Information Agent, incurred
in connection with the Fauth Offer.

     At its meeting of July 15, 1999, after considering numerous factors, the
Board of Directors of the Company unanimously rejected the Fauth Offer. The
Board of Directors considered the Fauth Offer to be highly contingent and
without adequate assurances that financing would be available to carry it out.
In addition, the Board of Directors concluded that acceptance of the Fauth Offer
and the Fauth proxy proposals would make it extremely difficult for the Company
to seek out alternative transactions at a greater value. The Board of Directors
strongly and unanimously recommends that the Fauth Offer be rejected by the
Company's stockholders.

     (b) The Company's Board of Directors has been aware of Fauth's interest in
the Company for some time. On November 25, 1998, two Board members met with
Fauth. These members reported on their meeting with Fauth at the December 10,
1998, Board meeting and Fauth's interest was discussed. Mr. James Doubles,
Chairman, President and Chief Executive Officer of the Company, met with Fauth,
and Fauth reaffirmed his interest in the Company, including his interest in
taking the Company private. Mr. Doubles reported these discussions to the Board
at the March 26, 1999, Board meeting. At that time the Board also discussed
Fauth's March 11, 1999, letter in which he proposed taking the Company private,
the Company's five-year projections for revenue, earnings and earnings per
share, data on the Company's stock history for a two-year period, and
information submitted by management outlining various valuation methods and
providing preliminary estimates of the Company's stock value. After


                                       5


discussion, the Company's Board determined it needed further study of the
matter, and management was directed to bring advisors to the April Board meeting
who could give an educational presentation and provide insights on means of
enhancing stockholder value.

     At the April 23, 1999, Board meeting, a principal of William Blair &
Company ("William Blair"), an investment banking firm, made a presentation on
possible ways to enhance stockholder value. He also discussed market statistics
of various companies, including measurement and control instrumentation
companies. Following that presentation, the Board unanimously agreed to reject
Fauth's overture. The Board agreed that remaining as an independent public
company was in the long-term best interest of the Company's stockholders. Mr.
Doubles communicated this to Fauth by letter dated April 27, 1999.

     On May 13, 1999, two attorneys representing Fauth met with the Company's
counsel. They advised the Company's counsel that Fauth did not intend to accept
the Board's decision to remain an independent public company and that Fauth
intended to pursue the matter aggressively. This meeting was followed, on May
21, 1999, by Fauth's demand for a stockholder list and other corporate
information. On June 1, 1999, the Company provided Fauth with the information
that he was entitled to under Minnesota law.

     Fauth's interest in the Company was again discussed at the May 27, 1999,
Board meeting, at which time it was concluded that William Blair would be
retained to advise the Board. The Board also scheduled a meeting in mid-June to
address the revised strategic and operational plans of the Company for the next
three to five years in light of the May 26, 1999, acquisition of Environmental
Systems Corporation. The initial strategic plan had been discussed previously at
the January Board meeting.

     By letter dated June 14, 1999, Fauth made a proposal to acquire the Company
for $12.50 per share, subject to various contingencies. The Board carefully
considered this proposal at the already scheduled June 16, 1999, Board meeting.
At this meeting, William Blair, which was already scheduled to make a
comprehensive presentation regarding the Company and its options, also provided
the Board with a preliminary analysis of Fauth's June 14, 1999, proposal. The
Board considered, among other things,

o    the Company's historical financial results;

o    the Company's current financial condition, including the recent acquisition
     of Environmental Systems Corporation;

o    the Company's strategic and operational plans which evaluate and set forth
     plans for the Company's current technologies and markets;

o    the status of the Company's research and development and new project
     prospects;


                                       6


o    possible acquisitions;

o    the capability of the Company's management and other employees;

o    stock market information, including an analysis of selected publicly traded
     companies comparable to the Company, an analysis of selected comparable
     acquisition transactions, historical trading prices and relationships to a
     number of market indices, a discounted cash flow analysis of the Company's
     future earnings and general stock price premiums for sale of control of
     public companies;

o    impact on employees, customers, community, suppliers, and others that have
     a relationship with the Company; and

o    Fauth's background and the companies he had previously acquired.

Following this analysis, the Board voted unanimously to reject Fauth's June 14,
1999 proposal, and Mr. Doubles confirmed this by letter dated June 18, 1999.

     On June 16, 1999, before the Company could respond to his June 14, 1999
proposal, Fauth and his affiliates initiated a proxy contest. Fauth and his
affiliates are seeking to replace three current members of the Board, including
the Chairman, President and Chief Executive Officer, James E. Doubles, with
himself and two of his subordinates. Fauth and his affiliates are also asking
the Company's stockholders to approve a number of changes to the Company's
Articles of Incorporation and bylaws. Approval of each of these proposals is a
condition to consummation of the Fauth Offer. The Company believes that these
proposals will, in the aggregate, impede the Company's ability to deal with the
problem of hostile takeovers because they reduce the Board's opportunity to
evaluate takeover proposals, to study alternatives and to determine the best
course of action for the Company and its stockholders. In certain cases, the
proposals of Fauth and his affiliates give a single director veto power with
regard to the Company's response to a hostile takeover or certain other
corporate actions.

     On July 9, 1999, Fauth and his affiliates announced the Fauth Offer. On
July 11, 1999, the Board of Directors met with its financial advisors and
concluded it could not evaluate the Fauth Offer at that time because the details
had net yet been made available.

     On July 15, 1999, the Company's Board met with representatives of William
Blair and the Company's counsel to consider the Fauth Offer. At this special
meeting, the Company's Board of Directors unanimously determined to reject the
Fauth Offer, based upon the Board's determination that the offer is not in the
best interest of the Company and its stockholders. The Board considered the
Fauth Offer to be highly contingent and without adequate assurances that
financing would be available to carry it out. In addition, the Board concluded
that acceptance of the Fauth Offer and the Fauth proxy proposals would make it
extremely difficult for the Company to seek out alternative transactions at a
greater value.


                                       7


     Accordingly, based upon its deliberations over the past six months, as
summarized above, the Board of Directors unanimously recommends that the
Company's stockholders reject the offer and not tender their shares. In reaching
its determinations and recommendations described above, the Board of Directors
considered a number of factors, including the following:

     1. The numerous contingencies contained in the Fauth Offer, including many
that are within Fauth's exclusive control. Other contingencies would require the
shareholders at the Annual Meeting to waive anti-takeover provisions which have
been in effect for Minnesota public corporations since the mid-1980's. The Board
believes that these and other actions to be presented by Fauth at the Annual
Meeting would strip the Board of its ability to control the acquisition process
and obtain the maximum price for the Company's stockholders. In the last month
alone, as a result of your Board's firm rejection of the $12.50 proposal, Mr.
Fauth has raised his tender offer to $14.00 per share.

     2. The extremely vague and incomplete financing package set forth in the
tender offer.

     3. The Company's business, assets, financial condition and future
prospects, strategic direction of the Company's business, current conditions in
the instrumentation industry, and the historical and current market prices for
the Company's Shares.

     4. The Company's carefully structured long-term plan of independent growth
through internal expansion and selective, strategic, negotiated acquisitions.

     5. The financial advice of the Company's independent financial advisor,
William Blair & Company. This financial advice included extensive stock market
information, discussion of possible future prices for the Company's Shares if
the Company's plans are achieved, and discussion of other companies which have
expressed an interest in the Company.

     6. The opinion of the Company's management that the terms of the Fauth
Offer are inadequate based on its knowledge of the Company's business, its views
as to the long-term financial plan and future prospects of the Company, the
Company's long-term research and development efforts, and the Company's recent
acquisitions, including Environmental Systems Corporation.

     7. Fauth's background and the companies he had previously acquired.

     8. The Board of Directors belief that the highly leveraged acquisition of
the Company by Fauth, as contemplated by the Fauth Offer, would have a
significantly adverse effect on the Company's relationships with its employees,
customers, suppliers and other constituencies.


                                       8


     The Company's Board also authorized William Blair to continue its efforts
to explore strategic alternatives, including seeking offers of greater value and
undertaking further discussions with Fauth and his representatives.

     The forms of a letter to stockholders and press release communicating the
recommendation of the Board of Directors of the Company to reject the Fauth
Offer are filed as Exhibits (a)(1) and (a)(2) to this Statement.

Item 5. Persons Retained, Employed or to Be Compensated

     The Company has retained William Blair to act as its financial advisor to
render financial advisory and investment banking services in connection with the
following:

o    to assist the Company in analyzing its strategic options to enhance
     stockholder value, including, without limitation, evaluating possible
     acquisitions of other companies, a possible corporate restructuring or
     recapitalization, and a possible business combination (through a tender
     offer, merger, sale or exchange of stock, sale of all or a substantial part
     of its assets or otherwise) of the Company with another party
     (collectively, the "Possible Transaction"); and

o    the attempt of Fauth and his affiliates to acquire the Company.

     At the July 11, 1999, Board meeting, the Board further instructed William
Blair to continue its work on possible ways to enhance stockholder value,
including conducting a search to seek out a potential merger partner. In
pursuing the foregoing, William Blair is authorized, among other things, to make
a market check to determine the value of the Company if it were put up for sale.

     The Company is paying a retainer fee of $25,000 per quarter for a minimum
of four quarters payable in cash for William Blair's services. In the event
William Blair renders an opinion as to the fairness, from a financial point of
view, of a Possible Transaction or advises the Board that it is unable to render
such an opinion for a Possible Transaction the Company will pay William Blair a
specified cash opinion fee, payable promptly after the rendering of such opinion
or the communication of such advice.

     If the attempt of Fauth and his affiliates to acquire the Company is
withdrawn or terminated prior to consummation of a Possible Transaction and
Fauth and his affiliates make no significant further effort toward acquisition
of the Company for a specified period of time, the Company will pay William
Blair an additional specified fee for its efforts in assisting the Company in
any proxy contest or similar efforts.

     In the event the Company consummates an acquisition involving total
consideration in excess of $25 million in which William Blair renders financial
advisory and investment banking services, the Company will pay William Blair a
specified fee for


                                       9


such advice. Also, in the event a possible transaction is consumated, the
Company will pay William Blair a specified fee.

     The Company has also agreed to reimburse William Blair for its expenses
(including legal fees and expenses of counsel) and to indemnify it against
certain liabilities, including liabilities and expenses which may arise under
federal securities laws.

     The Company has retained Corporate Investor Communications, Inc. ("CIC") to
solicit proxies pursuant to the Proxy Statement and to provide related advisory
services. The Company has agreed to pay CIC a fee of $35,000, together with
reimbursement of out-of-pocket expenses, for its services.

     Neither the Company nor any person acting on its behalf currently intends
to employ, retain or compensate any other person to make solicitations or
recommendations to stockholders in connection with the Fauth Offer.

Item 6. Recent Transactions and Intent with Respect to Securities

     (a) To the best of the Company's knowledge, no transactions in the Shares
have been effected during the past 60 days by the Company or any executive
officer, director, affiliate or subsidiary of the Company, except for the
following:

o    On July 13, 1999, Kenneth J. Roering, a director of the Company, acquired
     3,000 Shares at $8.00 per share for a total of $24,000 upon the exercise of
     stock options;

o    On July 15, 1999, Lawrence J. Whalen, a director of the Company, acquired
     3,000 Shares at $8.00 per share for a total of $24,000 upon the exercise of
     stock options;

o    On July 15, 1999, Donald M. Sullivan, a director of the Company, acquired
     3,000 Shares at $8.00 per share for a total of $24,000 upon the exercise of
     stock options;

o    During the period May 28, 1998 through May 27, 1999, a total of 68,189
     Shares were purchased under the Employee Stock Purchase Plan of 1994 (the
     "1994 Plan") at a price per share of $7.04 (85% of fair market value of
     $10.875). The number of employees participating during the period under the
     1994 Plan is 163.

o    During the period commencing June 22, 1999, and ending June 21, 2000, a
     total of 120,000 Shares have been elected for purchase under the 1994 Plan
     at initial price per share of $9.56 per share (85% of fair market value of
     $11.25). The number of employees participating during this period under the
     1994 Plan is 289, including James E. Doubles and Robert F. Gallagher,
     executive officers of the Company.


                                       10


     (b) To the best of the Company's knowledge, none of its executive officers,
directors, affiliates or subsidiaries presently intends to tender into the Fauth
Offer any Shares which are held of record or beneficially owned by such persons.

Item 7. Certain Negotiations and Transactions by the Subject Company

     (a) The Company, directly or through William Blair, is engaged in
preliminary exploratory discussions with a number of companies concerning a
possible business combination. The Company also is discussing the sale of one of
its subsidiaries. William Blair also is assisting the Company as described in
Item 5 above in exploring options for enhancing stockholder value. Except for
the foregoing activities, no negotiation is underway or is being undertaken by
the Company in response to the Fauth Offer which relates to or would result in
(1) an extraordinary transaction, such as a merger or reorganization, involving
the Company or any of its subsidiaries; (2) a purchase, sale or transfer of a
material amount of assets by the Company or any of its subsidiaries; (3) a
tender offer for or other acquisition of securities by or of the Company; or (4)
