ARTWORK DESCRIPTIONS FOR INSIDE FRONT COVER

Photo 1 -- Photo of part of the Company's plastics quality control system. The
photo depicts the Company's sensor hanging from a metal track suspended over a
flat sheet of plastic foil to be scanned. The plastic foil is rolling under the
sensor.

The Company's quality control systems for the plastics industry measure and
control the thickness of the plastic film and coatings on web material. The
measurements are made on-line in the process at the point of manufacture,
enabling adjustments to occur immediately, thereby reducing material waste.

Photo 2 -- Photo of the Company's thickness gauge strip system on a steel mill
floor. The photo shows a glowing rolled strip of metal being transported on a
roller table along the mill floor. A C-frame structure containing the Company's
sensors suspends the sensor over the steel strip (however, lower arm of C-frame
structure is not shown because it is obstructed by roller table). Also included
in the photo are various walkways, exhaust vents, industrial tools and gauges.

The Company manufactures thickness gauges for hot and cold rolled steel. In the
left foreground, a gauge is shown which measures, without contact, the thickness
of hot rolled steel strip, with fast response and high accuracy, one of the most
significant quality parameters of the produced material.

Stock declared and effected in May 1997. Investors should carefully consider the
information set forth under the heading "Risk Factors."

THE COMPANY

Metrika Systems Corporation ("Metrika Systems" or the "Company") develops,
manufactures and markets on-line industrial process optimization systems that
employ proprietary ultra-high speed advanced scientific measurement technologies
for applications in raw materials analysis and finished materials quality
control. The Company is a pioneer in the development of process optimization
systems that provide real-time, non-destructive analysis of the composition of
raw materials in basic materials production processes, including coal, cement
and minerals. The Company also manufactures advanced systems which are used to
measure and control parameters such as material thickness, coating thickness and
coating weight in web-type materials, such as metal strip, rubber and plastic
foils. Customers use these systems to improve product quality and consistency,
lower material costs, reduce energy consumption and minimize waste. The Company
believes that the current total annual worldwide market for process optimization
instruments and systems is in excess of $2 billion. The Company believes its
process optimization products and systems currently address an annual market
segment of approximately $500 million.

The Company's systems make real-time, on-line, non-invasive,
non-destructive, precise measurements of materials using advanced scientific
measurement techniques, including gamma spectroscopy, beta particle detection,
laser spectroscopy, x-ray fluorescence and ultrasound. The Company's systems
incorporate proprietary intelligent sensors that have been developed for
specific production processes along with ultra-high speed signal processing
electronics capable of processing, in some cases, up to one million electronic
impulses per second resulting from the detection of excited particles such as
photons. These systems can be combined with the Company's proprietary real-time
software to form integrated process optimization systems designed to fit the
customer's specific application. The Company has developed a reputation for
rugged and reliable sensor technology capable of operating in hostile industrial
environments. The Company's products can generate significant savings to the
customer as a result of reduced manufacturing costs, reduced material waste,
decreased energy costs and in some cases, savings in capital investment.

The Company's strategy is to capitalize on the large market opportunities
for advanced measurement systems in the basic materials industries and to
exploit its core competencies and proprietary technologies through an evolving
series of optimization systems. As part of this strategy, the Company intends to
expand the geographic scope of its addressed markets. In particular, the Company
intends to expand the market presence of its on-line finished materials quality
control products in Asia, the U.S. and Latin America by drawing on the global
market expertise and existing global sales force of its on-line raw materials
analyzer business. In addition, the Company intends to aggressively pursue
market opportunities for its on-line raw materials analyzer products created by
the rapid infrastructure development and new manufacturing capacity occurring in
Asia and Latin America. Further, the Company intends to pursue opportunities to
retrofit the large existing base of coal mines, coal-burning utilities and
cement plants with its on-line process optimization systems. The Company also
intends to target new industries such as the pharmaceutical, agrochemical,
industrial chemical and glass industries and plans to make strategic
acquisitions of complementary businesses.

RISK FACTORS

In addition to the other information in this Prospectus, investors should
carefully consider the following risk factors when evaluating an investment in
the shares of Common Stock offered hereby. This Prospectus contains
forward-looking statements that involve risks and uncertainties, such as
statements of the Company's plans, objectives, expectations and intentions. The
cautionary statements made in this Prospectus should be read as being applicable
to all forward-looking statements wherever they appear in this Prospectus. The
Company's actual results could differ materially from those discussed herein.
Factors that could cause or contribute to such differences include those
discussed below, as well as those discussed elsewhere in this Prospectus.

Dependence on Capital Spending Policies. The Company's customers include
coal burning utilities, coal mines, cement manufacturers, and manufacturers of
web-type materials such as steel, plastic and rubber. The capital spending
policies of these companies can have a significant effect on the demand for the
Company's products. Such policies are based on a wide variety of factors,
including the resources available to make such purchases, the spending
priorities among various types of process control equipment or techniques and
policies regarding capital expenditures during recessions. Any decrease in
capital spending by these customers could have a material adverse effect on the
Company's business and results of operations. Further, the Company's growth is
dependent in part on construction and upgrade of manufacturing plants in the
basic materials industries. A recession in one or more markets could cause a
slowdown or reduction in capital spending and in new plant construction. Growth
of the Company's on-line finished materials quality control business has
recently been adversely affected by a recession in Germany.

Uncertainty of Market Acceptance of New Products. Certain of the Company's
products represent alternatives to traditional instruments and methods. As a
result, such products may be slow to achieve, or may not achieve, market
acceptance, as customers may seek further validation of the efficiency and
efficacy of the Company's technology. This is particularly true where the
purchase of the product requires a significant capital commitment. Further,
because on-line process control systems are incorporated into a customer's
production line, a decision to invest in these systems involves significant
operating risks if the system fails or shuts down. The Company intends to expand
its product base by adapting its proprietary technologies for new applications
in broader industry segments including the pharmaceutical, agrochemical and
industrial chemical industries. The Company believes that, to a significant
extent, its growth prospects depend on the continuing acceptance by a broader
group of customers and by broader industry segments of its new products and
technologies. There can be no assurance that the Company will be successful in
adapting its proprietary technologies for new applications, in obtaining these
acceptances or, if obtained, that such acceptances will be sustained. The
failure of the Company to obtain and sustain such acceptances could have a
material adverse effect on the Company's business and results of operations.

Technological Change and New Products. The market for on-line process
optimization systems is characterized by changing technology, evolving industry
standards and new product introductions. The Company's future success will
depend in part upon its ability to enhance its existing products and to develop
and introduce new products and technologies to meet changing customer
requirements and to successfully serve broader industry segments. The Company is
currently devoting significant resources toward the enhancement of its existing
products and the development of new products and technologies. There can be no
assurance that the Company will successfully complete the enhancement and
development of these products in a timely fashion or that the Company's current
or future products will satisfy the needs of the on-line process optimization
systems markets. Any failure to complete the enhancement and development of
these products or the failure of the Company's current or future products to
satisfy market needs could have a material adverse effect on the Company's
business and results of operation.

Risks Associated with Acquisition Strategy. The Company's strategy
includes the acquisition of businesses and technologies that complement or
augment the Company's existing product lines.

6
8

Promising acquisitions are difficult to identify and complete for a number of
reasons, including competition among prospective buyers, the need for regulatory
approvals, including antitrust approvals, and the high valuations of businesses
resulting from historically high stock prices in many countries. There can be no
assurance that the Company will be able to complete future acquisitions or that
the Company will be able to successfully integrate any acquired business. In
order to finance such acquisitions, it may be necessary for the Company to raise
additional funds through public or private financings. Any equity or debt
financing, if available at all, may be on terms which are not favorable to the
Company and, in the case of equity financing, may result in dilution to the
Company's stockholders.

International Operations and International Sales. In 1994, 1995, 1996 and
the three months ended March 29, 1997, sales originating outside the U.S.
accounted for 59%, 58%, 56% and 45%, respectively, of the Company's total
revenues. In addition, in 1994, 1995, 1996 and the three months ended March 29,
1997, U.S. export sales accounted for 24%, 23%, 26% and 39%, respectively, of
the Company's total revenues. The Company anticipates that sales outside the
U.S. and U.S. export sales will continue to account for a significant percentage
of the Company's total revenues. The Company intends to continue to expand its
presence in international markets. International revenues are subject to a
number of risks, including the following: agreements may be difficult to enforce
and receivables difficult to collect through a foreign country's legal system;
foreign customers may have longer payment cycles; foreign countries may impose
additional withholding taxes or otherwise tax the Company's foreign income,
impose tariffs or adopt other restrictions on foreign trade; U.S. export
licenses may be difficult to obtain; the protection of intellectual property in
foreign countries may be more difficult to enforce; and fluctuations in exchange
rates may affect product demand and may adversely affect the profitability in
U.S. dollars of products and services provided by the Company in foreign markets
where payment for the Company's products and services is made in the local
currency. In 1996, effects of currency translation, due to a stronger U.S.
dollar, decreased revenues by $0.9 million. Further, a significant portion of
the Company's business is conducted in foreign countries, particularly Germany.
Foreign operations are also subject to certain risks such as general economic
conditions in the countries in which the Company operates, unexpected changes in
regulatory requirements, compliance with a variety of foreign laws and
regulations and overlap of different tax structures. Tax rates in certain
foreign countries exceed that of the United States and foreign earnings may be
subject to withholding requirements or the imposition of tariffs, exchange
controls or other restrictions. There can be no assurance that any of these
factors will not have a material adverse effect on the Company's business and
results of operations.

Competition. The Company encounters intense competition in the sale of its
on-line finished materials quality control products. The Company believes that
the principal competitive factors affecting the market for on-line process
optimization systems include quality and reliability, accuracy, price, customer
service and support, ease of use, distribution channels, technical features and
compatibility with customers' manufacturing processes. Certain of the Company's
competitors have greater resources, manufacturing and marketing capabilities,
technical staff and production facilities than those of the Company. As a
result, they may be able to adapt more quickly to new or emerging technologies
and changes in customer requirements, or to devote greater resources to the
promotion and sale of their products than can the Company. Further, competition
with respect to all of the Company's products could increase if new companies
enter the market or if existing competitors expand their product lines. There
can be no assurance that competitors of the Company will not develop
technological innovations that will render products of the Company obsolete.

Proprietary Rights. Proprietary rights relating to the Company's products
will be protected from unauthorized use by third parties only to the extent that
they are covered by valid and enforceable patents or are maintained in
confidence as trade secrets. The Company has 11 U.S. patents which have
expiration dates ranging from 1998 through 2012. The Company also owns
corresponding foreign patents in a number of jurisdictions throughout the world.
There can be no assurance that any patents now or hereafter owned by the Company
will afford protection against competitors. Proceedings initiated by the Company
to protect its proprietary rights could result in substantial costs to the
Company. There can be no assurance that competitors of the Company, some of whom
have substantially greater

7
9

resources than those of the Company, will not initiate litigation to challenge
the validity of the Company's patents, or that they will not use their resources
to design comparable products that do not infringe the Company's patents. The
Company could incur substantial costs and diversion of management resources with
respect to the defense of any such claims, which could have a material adverse
effect on the Company's business, financial condition, and results of operation.
Furthermore, parties making such claims could secure a judgment awarding
substantial damages, as well as injunctive or other equitable relief, which
could effectively block the Company's ability to make, use, sell, distribute or
market its products and services in the U.S. and abroad. There may also be
pending or issued patents held by parties not affiliated with the Company that
relate to the Company's products or technologies. In the event that a claim
relating to proprietary technology or information is asserted against the
Company, the Company may need to acquire licenses to, or contest the validity
of, any such competitor's proprietary technology. It is likely that significant
funds would be required to contest the validity of any such competitor's
proprietary technology. There can be no assurance that any license required
under any such competitor's proprietary technology would be made available on
acceptable terms or that the Company would prevail in any such contest. There
can be no assurance that the steps taken by the Company to protect its
proprietary rights will be adequate to prevent misappropriation of its
technology or independent development by others of similar technology. In
addition, the laws of some jurisdictions do not protect the Company's
proprietary rights to the same extent as the laws of the U.S. There can be no
assurance that these protections will be adequate.

Dependence on Sole-source Suppliers. Various components of the Company's
products are supplied by sole-source vendors. The Company has not experienced
significant difficulty in obtaining adequate supplies from these vendors, and
has identified alternate suppliers. However, there can be no assurance that the
unanticipated loss of a single vendor would not result in delays in shipment or
in the introduction of new products. Any such delays could have a material
adverse effect on the Company's business or results of operations.

Government Regulations and Approvals. The market for certain of the
Company's products, both in the U.S. and abroad, is subject to or influenced by
various domestic and foreign clean air and consumer protection laws. The Company
designs, develops and markets its products, in part, to meet customer needs
created by existing and anticipated regulations, and any changes in these
regulations may adversely affect consumer demand for the Company's products.

Potential Fluctuations in Quarterly Performance. Many of the Company's
products are large systems that may require significant capital expenditures.
Consequently, the timing of sales of these systems could affect the Company's
quarterly earnings. Further, the Company's quarterly operating results may also
vary significantly depending on a number of other factors, including the size,
timing and shipment of individual orders, changes in pricing by the Company or
its competitors, discount levels, seasonality of revenue, foreign currency
exchange rates, the mix of products sold, the timing of the announcement,
introduction and delivery of new product enhancements by the Company and its
competitors and general economic conditions. Generally, the Company recognizes
product revenues upon shipment of its products. Revenues on substantially all
contracts are recognized using the percentage-of-completion method. Typically,
the Company experiences higher revenues in the second half of each year due to
seasonality experienced by its on-line finished materials quality control
business primarily because customers tend to place their orders earlier in the
year so that they can have the systems installed either during the holiday
season in the third quarter or between Christmas and the New Year. Because
certain operating expenses of the Company are based on anticipated capacity
levels and a high percentage of the Company's expenses are fixed for the short
term, a small variation in the timing of recognition of revenue can cause
significant variations in operating results from quarter to quarter. There can
be no assurance that any of these factors will not have a material adverse
effect on the Company's business or results of operation.

Dependence on Key Personnel. The Company's success depends to a
significant extent upon a number of key employees, including members of senior
management. The loss of the services of one or more of these key employees could
have a material adverse effect on the Company. The Company has not obtained and
does not intend to obtain key-man life insurance policies for any key employee.
The

8
10

Company believes that its future success will depend in part on its ability to
attract, motivate and retain highly skilled technical, managerial and marketing
personnel. Competition for such personnel is intense and there can be no
assurance that the Company will be successful in attracting, motivating and
retaining key personnel. The failure to hire and retain such personnel could
materially adversely affect the Company's business and results of operations.

Shares Eligible for Sale After this Offering. At the conclusion of the
120-day period following the closing of this offering, the Company will file a

Additional dilution is likely to occur upon the exercise of outstanding stock
options. See "Dilution."

No Public Market; Potential Volatility of Stock Price. Prior to this
offering there has been no public market for the Common Stock and there can be
no assurance that an active trading market will develop or be sustained after
this offering. The initial offering price of the Common Stock will be determined
by negotiations between the Company and the Representatives of the Underwriters
and may not be indicative of future market prices. See "Underwriting" for a
discussion of the factors to be considered in determining the initial public
offering price. Factors such as fluctuations in the Company's operating results,
announcements of technological innovations or new contracts or products by the
Company or its competitors, government regulation and approvals, developments in
patent or other proprietary rights and market conditions for stocks of companies
similar to the Company could have a significant impact on the market price of
the Common Stock. There can be no assurance that the market price of the Common
Stock will not decline below the initial offering price.

Potential Conflict of Interest. For financial reporting purposes the
Company's financial results are included in the consolidated financial
statements of Thermo Instrument and Thermo Electron. The members of the Board of
Directors of the Company who are also affiliated with Thermo Electron or Thermo
Instrument will consider both the short-term and the long-term impact of
operating decisions on the Company as well as the impact of such decisions on
the consolidated financial results of Thermo Instrument and Thermo Electron. The
interest of Thermo Electron and Thermo Instrument on the one hand and the
Company on the other hand may differ. The Company is an indirect subsidiary of
Thermo Electron and is a party to various agreements with Thermo Electron. These
agreements may limit the Company's operating flexibility. See "Relationship with
Thermo Electron and Thermo Instrument."

Lack of Voting Control. The Company's shareholders do not have the right
to cumulate votes for the election of directors. Thermo Instrument, which will
own 63% of the voting stock of the Company after this offering, has the power to
elect the entire Board of Directors of the Company and to approve or

9
11

disapprove any corporate actions submitted to a vote of the Company's
stockholders. See "Relationship with Thermo Electron and Thermo Instrument" and
"Security Ownership of Certain Beneficial Owners and Management."

Lack of Dividends. The Company anticipates that for the foreseeable future
the Company's earnings, if any, will be retained for use in the business and
that no cash dividends will be paid on the Common Stock. Declaration of
dividends on the Common Stock will depend upon, among other things, future
earnings, the operating and financial condition of the Company, its capital
requirements and general business conditions. See "Dividend Policy."

THE COMPANY

The Company operated as two divisions of Thermo Instrument Systems Inc.
("Thermo Instrument") until its incorporation as a Delaware corporation in
November 1996. In connection with the Company's incorporation, Thermo Instrument
transferred to the Company the assets, liabilities and businesses of its
Gamma-Metrics subsidiary and Radiometrie division in exchange for 5,000,000
shares of the Company's common stock. As of May 27, 1997, Thermo Instrument
beneficially owned approximately 84% of the Company's outstanding Common Stock.
Unless the context otherwise requires, references in this Prospectus to the
Company or Metrika Systems refer to Metrika Systems Corporation and its
subsidiaries and the predecessor business which constitute the Company. The
Company's on-line raw materials analyzer business is conducted by its
Gamma-Metrics subsidiary based in San Diego, California, and its on-line
finished materials quality control business is conducted by its Radiometrie
division with operations in Erlangen, Germany and Gloucester, England. The
Company's principal executive offices are located at 5788 Pacific Center
Boulevard, San Diego, California 92121, and its telephone number is (619)
450-9649.

USE OF PROCEEDS

The net proceeds to be received by the Company from this offering are
estimated to be $31,090,000 ($35,858,500 if the Underwriters' over-allotment
option is exercised in full) assuming an initial offering price of $17.00 per
share and after deducting estimated underwriting discounts and commissions and
offering expenses. The principal purposes of this offering are to increase the
Company's equity capital, to create a public market for the Common Stock and to
facilitate future access by the Company to public equity markets. The Company
intends to use the net proceeds from this offering for general corporate
purposes, including the possible acquisition of one or more businesses, and to
fund research and development with respect to new products. The Company,
however, has no specific agreements or commitments with respect to any
acquisitions that would be material to the Company. Pending these uses, the
Company expects to invest the net proceeds from this offering primarily in
investment grade interest bearing or dividend bearing instruments, either
directly by the Company or pursuant to a repurchase agreement with Thermo
Electron in which the Company would in effect lend excess cash to Thermo
Electron, on a collaterized basis at market interest rates. See "Relationship
with Thermo Electron and Thermo Instrument -- Miscellaneous".

DIVIDEND POLICY

The Company anticipates that for the foreseeable future the Company's
earnings, if any, will be retained for use in the business and that no cash
dividends will be paid on the Common Stock.

DILUTION

As of March 29, 1997, the Company had a net tangible book value of
$12,393,000, or $2.08 per share. Net tangible book value per share is determined
by dividing net tangible book value (total tangible assets less total
liabilities) of the Company by the number of shares of Common Stock outstanding.
After giving effect to the sale by the Company of 2,000,000 shares of Common
Stock offered hereby (after deducting the estimated underwriting discounts and
commissions and offering expenses), the pro forma net tangible book value of the
Company as of March 29, 1997 would have been $43,483,000, or $5.46 per share.
This represents an immediate increase in net tangible book value of $3.38 per
share to the existing shareholders and an immediate dilution in net tangible
book value of $11.54 per share to investors purchasing Common Stock in this
offering. See "Risk Factors -- Immediate and Substantial Dilution." The
following table illustrates this per share dilution:

(1) If the Underwriters' over-allotment option were exercised in full, the pro
forma net tangible book value per share after this offering would be $5.84,
resulting in an immediate dilution of $11.16 per share to investors
purchasing shares in this offering. See "Underwriting."

(2) If all options outstanding at May 27, 1997 to purchase an aggregate of
298,000 shares of Common Stock at $15.00 per share were exercised in full,
in addition to the Underwriters' exercise of the over-allotment option, the
net tangible book value per share after this offering would be $6.15,
resulting in an immediate dilution of $10.85 per share to investors
purchasing shares in this offering.

The following table sets forth as of March 29, 1997 the number of shares of
Common Stock purchased from the Company, the total consideration paid to the

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

The Company develops, manufactures and markets on-line industrial process
optimization systems that employ proprietary ultra-high speed advanced
scientific measurement technologies for applications in raw materials analysis
and finished quality control. The Company is a pioneer in the development of
process optimization systems that provide real-time, non-destructive analysis of
the composition of raw materials in basic materials production processes,
including coal, cement and minerals. The Company also manufactures advanced
systems which are used to measure and control parameters such as material
thickness, coating thickness and coating weight in web-type materials, such as
metal strip, rubber and plastic foils. Customers use these systems to improve
product quality and consistency, lower material costs, reduce energy consumption
and minimize waste.

The Company intends to supplement its internal growth with strategic
acquisitions of complementary businesses. There can be no assurance that such
businesses will be available at prices attractive to the Company. On December
31, 1996, the Company acquired the assets, subject to certain liabilities, of
the Autometrics division of Svedala Industries Inc. ("Autometrics"), a
manufacturer and marketer of on-line analysis instruments for the minerals
processing industry.

A significant portion of the Company's sales are for large systems, the
timing of which can lead to variability in the Company's quarterly revenues and
income. In addition, in 1996 approximately 56% of the Company's revenues
originated outside the U.S. and approximately 26% of the Company's revenues were
exports from the U.S. Revenues originating outside the U.S. represent revenues
of the Company's on-line finished materials quality control business. The
operations of the on-line finished materials quality control business are
located in Germany, the United Kingdom and France, which principally sell in
their local currencies. Exports from the Company's U.S. operation are
denominated in U.S. dollars. The Company generally seeks to charge its customers
in the same currency as its operating costs. However, the Company's financial
performance and competitive position can be affected by currency exchange rate
fluctuations. Since the operations of the on-line finished materials quality
control business are conducted in Europe, principally Germany, the Company's
operating results could be adversely affected by capital spending and economic
conditions in Europe. The Company's operating results have been adversely
affected by a recession in Germany. The Company's strategy is to expand its
on-line finished materials quality control business in the U.S. and Asian
markets, which in turn may reduce the Company's exposure to European market
conditions.

QUARTERLY RESULTS

The following table sets forth certain unaudited quarterly financial
information for each of the four quarters in the period ended December 28, 1996
and for the quarter ended March 29, 1997. The Company believes that this
information has been presented on the same basis as the audited financial
statements appearing elsewhere in this Prospectus and, in the opinion of the
Company, includes all adjustments (consisting only of normal, recurring
adjustments) necessary to present fairly the unaudited quarterly results when
read in conjunction with the audited financial statements of the Company and
related notes thereto included elsewhere in the Prospectus. The operating
results for any quarter are not necessarily indicative of the operating results
for any future period.

Revenues increased from $11.6 million in the first quarter of 1996 to $14.3
million in the fourth quarter of 1996, principally due to sales growth at the
on-line raw materials analyzer business, resulting from increased sales in
international markets. Revenues decreased to $12.6 million in the first quarter
of 1997 from $14.3 million the fourth quarter of 1996, principally due to a $2.1
million decrease in sales at the on-line finished materials quality control
business, resulting primarily from a decrease in demand at the German operations
of this business. Improvement in the gross profit margin from 41% in the first
quarter of 1996 to 43% in the second quarter of 1996 reflects improvement at the
on-line finished materials quality control business due to higher costs incurred
in the first quarter of 1996 related to the introduction of new products, offset
in part by a decrease in gross profit margin at the on-line raw materials
analyzer business primarily due to shipments of older, lower-margin products.
The increase in gross profit margin from 46% in the third quarter of 1996 to 50%
in the fourth quarter of 1996 reflects margin improvement at the on-line raw
materials analyzer business principally due to manufacturing efficiencies as a
result of an increase in volume, and margin improvement at the on-line finished
materials quality control business primarily due to a reduction in manufacturing
costs relating to new products. The decrease in the gross profit margin from the
fourth quarter of 1996 to the first quarter of 1997 was primarily due to a
decrease at the on-line finished materials quality control business, resulting
primarily from a decrease in volume.

RESULTS OF OPERATIONS

Three Months Ended March 29, 1997 Compared With Three Months Ended March 30,
1996

Revenues increased 9% to $12.6 million in the three months ended March 29,
1997 from $11.6 million in the three months ended March 30, 1996, reflecting an
increase of $2.3 million at the on-line raw materials analyzer business
primarily due to increased sales in international markets and the inclusion of
$0.7 million in revenues from Autometrics, acquired December 31, 1996. These
increases were offset in part by a $1.1 million decrease in revenues at the
on-line finished materials quality control business due

15
17

to a decrease in demand at the German operations of this business. Revenues
decreased $0.2 million due to the unfavorable effects of currency translation
due to the strengthening of the U.S. dollar. The future sales growth of the
Company will depend in part upon increasing industry acceptance of its on-line
raw materials analyzers, as well as the Company's ability to further penetrate
the U.S. and Asian markets for its on-line finished materials quality control
systems.

The gross profit margin increased to 44% in the three months ended March
29, 1997 from 41% in the three months ended March 30, 1996. The gross profit
margin at the on-line finished goods quality control business improved to 39% in
the three months ended March 29, 1997 from 34% in the three months ended March
30, 1996 due to higher costs incurred in the 1996 period related to the
introduction of new products, and an increase in higher-margin sales resulting
from the introduction of such new products. These improvements were offset in
part by a decrease in gross profit margin at the on-line raw materials business
from 52% in the three months ended March 30, 1996 to 48% in the three months
ended March 29, 1997 resulting principally from the inclusion of lower-margin
revenues at Autometrics.

Selling, general and administrative expenses as a percentage of revenues
were 27% in the three months ended March 29, 1997 and March 30, 1996. Research
and development expenses increased to $1.0 million in the three months ended
March 29, 1997 from $0.7 million in the three months ended March 30, 1996,
primarily due to an increase in product development expenses at the on-line raw
materials analyzer business.

Interest income increased $0.2 million in the three months ended March 29,
1997 primarily due to interest earned on the invested net proceeds from the
Company's December 1996 private placement.

The effective tax rate was 40% in the three months ended March 29, 1997 and
March 30, 1996. The rate exceeds the statutory federal income tax rate primarily
due to the impact of state income taxes, nondeductible amortization of costs in
excess of net assets of acquired companies and foreign tax rate and tax law
differences.

1996 Compared With 1995

Revenues increased 13% to $52.0 million in 1996 from $46.0 million in 1995,
reflecting sales growth at both the on-line raw materials analyzer and finished
materials quality control businesses. Revenues increased $3.4 million at the
on-line raw materials analyzer business primarily due to growing acceptance of
its product line in international markets, and $3.5 million at the on-line
finished materials quality control business largely due to the introduction of
its quality control product line in Asia. Revenues decreased $0.9 million due to
the unfavorable effect of currency translation due to the strengthening of the
U.S. dollar.

The gross profit margin increased to 45% in 1996 from 44% in 1995. The
gross profit margin at the on-line raw materials analyzer business improved to
51% in 1996 from 44% in 1995 primarily due to product redesign and increased
sales of products which have lower manufacturing costs. The improvement was
offset in part by a decrease in the gross profit margin at the on-line finished
materials quality control business to 41% in 1996 from 44% in 1995, resulting
principally from additional costs associated with the continued introduction of
new products in the German operations of this business.

Selling, general and administrative expenses as a percentage of revenues
increased to 26% in 1996 from 25% in 1995, primarily due to increased marketing
efforts in international markets resulting in an increase in staffing and higher
travel expenses at the Company's on-line finished materials quality control
operations in Germany. Research and development expenses increased to $3.0
million in 1996 from $2.6 million in 1995, principally due to an increase in
product development expenses at the on-line finished materials quality control
business in Germany.

Interest expense decreased to $0.8 million in 1996 from $1.1 million in
1995 due to a decrease in short-term borrowings at the on-line finished
materials quality control business, as well as a decline in interest rates.
Interest income increased $0.1 million in 1996 primarily due to higher average
invested

16
18

balances of the Company's foreign operations, as well as interest earned on the
invested net proceeds from the Company's December 1996 private placement.

The effective tax rate was 40% in 1996 and 42% in 1995. These rates exceed
the statutory federal income tax rate primarily due to the impact of state
income taxes, nondeductible amortization of costs in excess of net assets of
acquired companies and foreign tax rate and tax law differences. The effective
tax rate decreased in 1996 primarily due to proportionately less income before
provision for income taxes from Germany, which is taxed at a higher rate.

1995 Compared With 1994

Revenues increased 19% to $46.0 million in 1995 from $38.6 million in 1994,
primarily due to a $3.5 million increase in sales at the on-line raw materials
analyzer business resulting from the introduction of the cross-belt analyzer
product line, as well as a $1.8 million increase in sales at the on-line
finished materials quality control business. Revenues increased $2.1 million due
to the favorable effects of currency translation due to the weakening of the
U.S. dollar.

The gross profit margin increased to 44% in 1995 from 43% in 1994,
principally due to an improvement in the gross profit margin at the on-line raw
materials analyzer business to 44% in 1995 from 40% in 1994 resulting from
product redesign and an increase in sales of products which have lower
manufacturing costs. The gross profit margin at the on-line finished materials
quality control business was unchanged at 44% in 1995 and 1994. Improvement in
the gross profit margin at the Company's operations in the United Kingdom and
France was offset by a decrease in gross profit margin at the German operations
resulting principally from additional costs associated with the introduction of
new products.

Selling, general and administrative expenses as a percentage of revenues
decreased to 25% in 1995 from 27% in 1994 largely due to an increase in
revenues. Research and development expenses increased to $2.6 million in 1995
from $2.3 million in 1994, primarily due to an increase in product development
expenses at the German division of the on-line finished materials quality
control business.

Interest expense increased to $1.1 million in 1995 from $0.7 million in
1994, primarily due to an increase in short-term borrowings at the on-line
finished materials quality control business.

The effective tax rate was 42% in 1995 and 46% in 1994. These rates exceed
the statutory federal income tax rate primarily due to the impact of state
income taxes, nondeductible amortization of costs in excess of net assets of
acquired companies and foreign tax rate and tax law differences. The effective
tax rate decreased in 1995 primarily due to proportionately less income before
provision for income taxes from Germany, which is taxed at a higher rate, and
increased benefits from a foreign sales corporation.

LIQUIDITY AND CAPITAL RESOURCES

Consolidated working capital was $10.2 million at March 29, 1997, compared
with $8.7 million at December 28, 1996. Included in working capital are cash and
cash equivalents of $17.4 million at March 29, 1997, compared with $20.2 million
at December 28, 1996. Additionally, included in working capital are short-term
borrowings and advances to or from parent company and affiliated companies of
$15.3 million at March 29, 1997 and $18.9 million at December 28, 1996 (see
Notes 5 and 6 to Consolidated Financial Statements).

During the three months ended March 29, 1997, $0.8 million was provided by
operating activities. Cash provided by the Company's operating results was
reduced primarily by a $2.4 million increase in inventories and unbilled
contract costs and fees, which was offset in part by a $1.3 million increase in
accounts payable. The increase in inventories and unbilled contract costs and
fees occurred principally at the on-line finished materials quality control
business, and resulted primarily from the timing of billing on
percentage-of-completion contracts.

During the three months ended March 29, 1997, the Company expended $1.4
million for investing activities. On December 31, 1996, the Company acquired the
assets, subject to certain liabilities, of Autometrics for $1.3 million in cash
(see Note 9 to Consolidated Financial Statements).

The Company's financing activities used $2.5 million of cash in the three
months ended March 29, 1997. During the three months ended March 29, 1997, the
Company increased its short-term borrowings by $4.6 million and repaid $0.2
million of its long-term obligation. A decrease in due to parent company and
affiliated companies used $6.9 million in cash during the three months ended
March 29, 1997 (see Note 5 to Consolidated Financial Statements).

During 1996, $7.8 million was provided by operating activities. Cash
provided by the Company's operating results was improved primarily by a $3.6
million decrease in unbilled contract costs and fees, offset in part by a $2.7
million decrease in billings in excess of contract costs and fees, which
resulted principally from the completion of two contracts.

The Company expended $0.7 million on purchases of property, plant and
equipment during 1996.

The Company's financing activities provided $11.1 million of cash in 1996.
In December 1996, the Company issued 1,935,667 shares of its common stock in a
private placement for net proceeds of $13.5 million (see Note 3 to Consolidated
Financial Statements). During 1996, the Company reduced its short-term
borrowings by $1.9 million, repaid $0.8 million of its long-term obligation and,
prior to its capitalization, transferred $2.4 million in cash to Thermo
Instrument. An increase in due to parent company and affiliated companies
provided $2.7 million in cash during 1996, primarily as a result of a $2.8
million borrowing from a wholly owned subsidiary of Thermo Instrument, which was
repaid in January 1997.

The Company plans to make capital expenditures of approximately $0.7
million in the remainder of 1997. Although the Company expects positive cash
flow from its existing operations, the Company anticipates it will require
significant amounts of cash for the possible acquisition of complementary
businesses and technologies. The Company expects that it will finance these
acquisitions through a combination of internal funds, including the net proceeds
from the sale of shares of Common Stock offered hereby, additional debt or
equity financing and/or short-term borrowings from Thermo Instrument or Thermo
Electron, although it has no agreement with these companies to ensure that funds
will be available, on acceptable terms, or at all. The Company believes that its
existing resources are sufficient to meet the capital requirements of its
existing businesses for the foreseeable future, including at least the next 24
months.

BUSINESS

The Company develops, manufactures and markets on-line industrial process
optimization systems that employ proprietary ultra-high speed advanced
scientific measurement technologies for applications in raw materials analysis
and finished materials quality control. The Company is a pioneer in the
development of process optimization systems that provide real-time,
non-destructive analysis of the composition of raw materials in basic materials
production processes, including coal, cement and minerals. The Company also
manufactures advanced systems which are used to measure and control parameters
such as material thickness, coating thickness and coating weight in web-type
materials, such as metal strip, rubber and plastic foils. Customers use these
systems to improve product quality and consistency, lower material costs, reduce
energy consumption and minimize waste.

Global competition is driving participants in the basic materials
industries to increase quality and reduce production costs. The optimization of
industrial production processes requires the collection and analysis of data for
both the composition of the materials used in the process as well as for
measuring the variance of the output from composition targets. Manufacturers
traditionally have used off-line sampling techniques and laboratory instruments
to obtain this data. The delays associated with these techniques do not permit
real-time adjustments to the manufacturing process. In order to provide
real-time process and quality control, measurement systems must be integrated
into the customer's production line and must rapidly measure, on a continuous
basis, the stream of the materials used or product produced, rather than a
sample. The systems must also generate precise and reliable measurements of the
materials using non-invasive and non-destructive measuring techniques. Finally,
the systems must rapidly analyze the measurement data and, using this data,
adjust automatically the manufacturing process in real-time, and often under
harsh industrial conditions.

The advent of rugged high-speed analytical measurement instrumentation has
only recently allowed for the development of on-line industrial process
optimization. The markets for the Company's systems, therefore, consist
primarily of the existing industrial facility base which may be retrofitted or
upgraded to incorporate on-line analysis, as well as new industrial facilities
which are expected to be built in the future. The Company estimates that there
are several thousand web-type material production lines, many of which the
Company believes have obsolete measurement and control systems, which could be
upgraded by incorporating the Company's on-line finished materials quality
control systems. The Company believes that the current total annual worldwide
market for process optimization instruments and systems is in excess of $2
billion. The Company believes its process optimization products and systems
currently address an approximately $500 million annual market segment.

Latin America by drawing on the global market expertise and existing global
sales force of its on-line raw materials analyzer business. In addition, the
Company intends to aggressively pursue market opportunities for its on-line raw
materials analyzer products created by the rapid infrastructure development and
new manufacturing capacity occurring in Asia and Latin America. Further, the
Company intends to pursue opportunities to retrofit the large existing base of
coal mines, coal-burning utilities and cement plants with its on-line process
optimization systems. The Company also intends to target new industries such as
the pharmaceutical, agrochemical, industrial chemical and glass industries. For
example, the Company is developing a laser-based spectroscopy system to be used
on-line to analyze the complex molecular structures of chemicals, which the
Company believes can be adapted for use in the pharmaceutical industry. The
Company also plans to make strategic acquisitions of complementary businesses.
On December 31, 1996, the Company acquired substantially all of the assets,
subject to certain liabilities, of the Autometrics division of Svedala
Industries, Inc. Autometrics designs, manufactures and markets on-line analysis
instruments for the minerals processing industry.

In January 1993, Thermo Instrument acquired Gamma-Metrics, a manufacturer
and marketer of on-line raw materials analyzers and in October 1993, Thermo
Instrument acquired all of the assets, subject to certain liabilities, of
Radiometrie, a manufacturer and marketer of on-line finished materials quality
control systems. Gamma-Metrics and Radiometrie operated as two divisions of
Thermo Instrument until the Company's incorporation as a Delaware corporation in
November 1996. In connection with the Company's incorporation, Thermo Instrument
transferred to the Company the assets, liabilities and businesses of the
Gamma-Metrics subsidiary and Radiometrie division in exchange for 5,000,000
shares of the Company's common stock. In December 1996, the Company acquired the
Autometrics business. The Company's on-line raw materials analyzer business is
conducted by its Gamma-Metrics subsidiary based in San Diego, California, and
its on-line finished materials quality control business is conducted by its
Radiometrie division with operations in Erlangen, Germany and Gloucester,
England. The Company's principal executive offices are located at 5788 Pacific
Center Boulevard, San Diego, California 92121, and its telephone number is (619)
450-9649.

On-line Raw Materials Analyzer Business

The Company manufactures on-line process optimization systems which
non-invasively measure and analyze the physical and chemical properties of a
stream of bulk solid materials in real-time. The systems are primarily used to
analyze the composition of raw materials used in certain basic industries, such
as coal, cement and minerals. The analysis technique used in the Company's
process optimization systems involves neutron interrogation. Under neutron
interrogation each element, when activated by neutrons, emits gamma rays of
unique characteristics which allow identification and quantification of the
elements present. Neutron interrogation has a major advantage over other on-line
measuring technologies such as x-rays because neutrons can deeply penetrate the
materials being analyzed. As a result, neutron interrogation allows the entire
stream of the material to be analyzed and eliminates the need for sampling. In
addition, it provides a more accurate analysis of the materials, especially
non-homogeneous materials, and can be used to analyze an extremely broad range
of materials. The systems contain proprietary sensors that detect gamma rays
emitted from the material being analyzed, which is activated by the neutron
source within the analyzer, yielding a composite gamma ray spectrum of the
material analyzed. Through on-line high speed spectroscopy, this spectrum is
then decomposed into its constituent parts by using microprocessors and
sophisticated real-time analytical software. The analyzer can then translate
this data into the elemental composition of the raw materials and can also use
the information to infer certain quality control parameters specific to the
process.

RAW MATERIALS PROCESS OPTIMIZATION SYSTEM

[DIAGRAM]

[This diagram depicts the Company's raw materials process optimization system
incorporated into a cement manufacturer's production line. The diagram contains
a series of boxes from the left margin to the center of the page depicting
containers, each of which holds high lime, low lime, shale or pyrite. Arrows
from each of the containers depict the release of these materials onto a
conveyer belt which enters a box entitled "Crossbelt Analyzer." An arrow from
the Crossbelt Analyzer to a box entitled "Raw Mill" depicts the flow of the
cement on the conveyer belt. Another arrow from the Crossbelt Analyzer to a box
entitled "Process Optimization Computer" depicts the flow of information which
is generated by the Crossbelt Analyzer and an arrow from the Process
Optimization Computer to the four containers of materials described above
depicts the flow of information from the computer to these containers to
regulate the amount of materials released onto the conveyer belt.]

The Company has developed extensive proprietary know-how and expertise
regarding the measuring capabilities of various on-line sensor technologies
based on the material being analyzed and the ultimate use of the material. The
Company draws on this expertise to modify and adapt its technology to maximize
the efficiency and performance of its sensors in each application. The Company's
systems also employ ultra-high speed microprocessors and electronic signaling
devices which enable the technology to be used on-line and in real-time. The
Company has developed proprietary high speed sophisticated software which
rapidly processes the collected data and compares it to input target parameters.
In this way, a control signal can be generated which is then used to modify
process variables to guide the process to the target parameters. In order to
provide real-time analysis, the Company's systems must be integrated with the
customer's production process, thus subjecting them to hostile conditions. In
response, the Company has designed its systems to be extremely rugged, durable
and accurate despite these demanding conditions.

Continuous on-line full-stream materials analysis provides faster and more
accurate analysis information than is possible with any conventional analysis
system. Traditional methods require numerous samples to be taken mechanically
from the materials at various stages of the production process, followed by
labor intensive sample preparation and laboratory analysis. Conventional
analysis techniques lag the production process and cannot be used effectively
for process control. In contrast, on-line, real-time analysis of the materials,
when coupled with the Company's software products, provides the customer with
immediate data regarding material composition and allows customers to
automatically and continuously adjust their manufacturing processes.

The Company's systems can reduce operating costs through a decrease in raw
material waste and energy use. The continuous monitoring and adjustment of the
manufacturing process enable the customer to use its raw materials more
efficiently. Product quality and consistency are also improved with use of the
Company's systems. For example, one typical application enables customers in the
cement industry to regulate closely the raw mix proportions of cement materials
to produce a more consistent product. Customers building new facilities can save
on capital outlay by reducing their investment in homogenizing
stacker/reclaimers and homogenizing silos, the traditional methods of
homogenizing raw materials. The Company's systems also reduce pollution,
optimize recycling and reduce material waste.

The Company currently markets the following family of products based on its
neutron interrogation technology.

On-line Coal Analyzer. The Company's on-line coal analyzer analyzes
streams of coal at a rate of up to four hundred tons per hour. The analyzer uses
neutron interrogation to determine the sulfur and ash concentration of the coal
on a continuous basis, and can also simultaneously compute the calorific value
of the coal, among other quality parameters. Customers can use the data to blend
or sort the coal depending on its quality. The Company has developed proprietary
high speed software that can be incorporated into the system to enable the
customer to automatically adjust and control the coal blending and sorting
process on-line.

Coal analyzers are currently used by coal mines and coal-burning utilities.
Increased competition in the coal industry has forced coal producers to reduce
costs while meeting increasingly stringent quality specifications. Coal mines
can use the coal analyzer to improve profitability by blending coals of
different quality to meet specific contract requirements or environmental
regulatory standards, by sorting out low sulfur coal which can be sold for a
premium or by controlling the specific gravity of separation in a coal cleaning
plant to ensure that quality specifications are met without over-cleaning. In
addition to ensuring more consistent quality, on-line coal analysis improves
recovery or yield from the mine, thus extending the life of a mine by reducing
the risk of premature exhaustion of low sulfur reserves that are required to
balance high sulfur reserves. Utility market deregulation and privatization,
coupled with environmental emission standards, has forced coal-burning utilities
to reduce costs while satisfying environmental emissions regulations.
Coal-burning utilities benefit from using on-line coal analyzers by enabling the
utility to accurately and rapidly test the coal to verify that the specification
of coal received under contract meets its specifications; to burn a more
cost-effective blend of high and low sulfur coal without violating environmental
emissions standards; to avoid investment in costly scrubbers; to generate
emission credits by controlling emissions; to improve boiler performance by
burning consistent quality coal; and to provide data verification of continuous
emission monitors.

Fifty-five percent of electricity production today in the U.S. is derived
from coal, and coal is the primary source of electricity in the rest of the
world. Further, it is estimated that approximately 45 new coal mines and
coal-burning utilities will be built each year for the next several years. In
China alone it is estimated that over 140 coal-fired utility plants will be
built between 1995 and 2005. The price of an on-line coal analyzer system ranges
from $300,000 to $500,000.

CrossBelt Analyzer. The Company's CrossBelt Analyzer ("CBA") is used
primarily by the cement industry to analyze the composition of cement raw
materials. The CBA is essentially a horizontal tunnel that is easily assembled
around the customer's conveyor belt. The CBA analyzes materials traveling on a
conveyor belt at speeds of up to 600 feet (200 meters) per minute and with
material flow rates in excess of 1,000 tons per hour. The CBA generates data
which provides the elemental composition of the entire stream of materials and
can also use the information to infer certain quality control parameters, such
as lime saturation factor and silica ratio. The CBA can incorporate high speed
proprietary software which allows the customer to automatically control
production processes.

Cement producers purchase the CBA to improve the economics of the plant by
reducing operating costs through the reduction in material waste and fuel costs.
The CBA is incorporated on-line into the customer's production process, which
enables the customer to control the mix of raw materials at the beginning of the
production line or to automatically control the blending of the cement additives
with crushed limestone and clay further down the production line. Both
approaches enable the producer to achieve more uniform cement quality. The CBA
controls the production process by using the analytical data it compiles to
automatically adjust the composition of the additive mix to achieve target
quality levels. This approach helps reduce variations in the materials fed into
the cement kiln yielding several benefits: lower energy consumption in the
cement mills, greater throughput and extended refractory life. Some customers
have reported that the use of the CBA has resulted in the reduction of fuel
costs. Fuel costs can constitute a significant percentage of a cement plant's
overall operating costs. For new plants, reduced variations in raw material
chemistry can also translate into major savings in the capital outlay for

22
24

homogenizing stacker/reclaimers and for homogenizing silos. This homogenizing
equipment is used to blend uneven raw materials. The price of a CBA system
ranges from $700,000 to $1 million.

The annual consumption of cement is expected to rise from the 1994 figure
of approximately 1.3 billion tons to approximately 1.8 billion tons by the year
2005. In addition, there are currently approximately 1,150 cement plants that
the Company has identified as potential customers for its CBA.

Mineral Slurry Analyzers. The Company recently developed an on-line
analyzer using neutron interrogation for use in the mineral extraction industry
for analyzing mineral slurry, a mixture of fine insoluble materials and water.
The Company has successfully tested its neutron-based mineral slurry analyzer at
a beta test site. Virtually all mined minerals, including iron, copper, nickel
and bauxite, must be separated and purified through a process called
beneficiation whereby the mined minerals are milled and mixed with water to form
a mineral slurry. The mineral of interest is then concentrated through a variety
of separation stages using reagents. The Company's neutron-based mineral slurry
analyzer, which analyzes the entire elemental composition of the slurry, can
greatly improve the efficiency of the beneficiation process by using the
collected data to automatically adjust various process parameters, including the
amount of reagents used in the process. The Company believes its neutron-based
mineral slurry analyzer is suitable for controlling the beneficiation process
for a wide variety of minerals.

On December 31, 1996, the Company acquired substantially all of the assets,
subject to certain liabilities, of Autometrics. Autometrics is a manufacturer of
mineral slurry analyzers. The assets acquired included two complementary product
lines and a customer base of approximately 300 customers, the majority of which
are located in the U.S. The two product lines acquired were Autometrics' on-line
x-ray slurry analyzers and its on-line particle size analyzers.

The x-ray slurry analyzers are used in the mineral extraction industry,
primarily for copper, iron and gold extraction, to measure the percentage of
elements present in mineral slurries and can be designed to automatically
control and adjust the amount of reagents used in the mineral beneficiation
process. The x-ray slurry analyzer uses x-ray fluorescence as its energy source
which is a less expensive energy source than neutron interrogation, and does not
penetrate the materials being analyzed as deeply as neutron interrogation. The
x-ray slurry analyzer provides customers, who do not require a comprehensive
analysis system, a cost-effective alternative to the Company's neutron-based
mineral slurry analyzer.

The on-line particle size analyzers are on-line real-time particle size
measuring instruments which have been used for over 15 years in the mineral
extraction industry. The on-line particle size analyzers use ultrasound together
with proprietary models to determine the particle size distribution and percent
solids in mineral slurries.

The price of the Company's mineral slurry analyzers ranges from $50,000 to
$500,000. The Company believes there are currently approximately 750 mineral
processing facilities worldwide for all of the Company's products.

Software Products. The Company complements its application specific sensor
technology with process optimization software. These systems use adaptive and
predictive controls to maximize material utilization, as well as to blend raw
materials to meet certain regulatory requirements in a cost-effective manner.
The process to extract, beneficiate and utilize raw materials is difficult to
control due to variances in chemistry, size and shape of the materials, and time
delays in the transport of materials from different points within the handling
system. Traditional process control methods cannot be utilized in these dynamic
and highly variable conditions. The Company's proprietary process control
software can accomplish these optimization tasks by performing model-based
estimation and by adaptively controlling source materials. The Company is the
only provider of process control software of this type for use by customers in
the raw materials segment of the basic materials industry.

A variety of products are manufactured and sold by the Company to address
the disparate needs of the cement, coal and energy industries. For the cement
industry, RAMOS(TM) achieves continuous blending for up to six sources of bulk
materials and three control parameters, while PREBOS(TM) is ideal for batch
blending, employing up to twelve sources. COBOS(TM) is used by coal producers
and coal-fired utilities to

23
25

blend coal to a target composition defined by sulfur, ash or calorific value and
thus achieve optimum fuel composition while meeting emission limits.

FastLab. The Company also offers its FastLab analyzer for rapid analysis
of samples off-line, with minimal sample preparation. The FastLab can be used
for numerous applications such as spot check analysis of raw materials, core
hole analysis, fuel analysis and chemical additives analysis. This product is
suitable for the same markets which use on-line elemental analysis. Its
advantages include its ease of use, its flexibility in handling multiple
material types and sampling locations and its low cost. The price of the
Company's FastLab analyzer ranges from $250,000 to $400,000.

Process Safety Instrumentation. Prior to entering the on-line process
optimization systems business, the Company's principal business was process
safety instrumentation for the nuclear power industry. The Company is a leading
supplier of process safety instrumentation in this industry. The Company's
instrumentation is designed to improve the safety and efficiency of nuclear
power plants. The Company produces several products for this market ranging in
price from $100,000 to $2.5 million. In addition, the Company offers automated
test equipment and some safety-related computer software for nuclear power
plants and other facilities where radioactive materials are used.

On-line Finished Materials Quality Control Business

The Company develops, manufactures and markets gauges and process
optimization systems for industrial manufacturing lines for continuous
production of certain web-type materials. Web-type materials are flat sheet
materials like paper, metal strip, plastic foil, rubber and glass. Typical high
volume products made from web-type materials include all types of vehicle body
and other parts, metals used for refrigerators and similar products,
beverage/food cans, cladding for buildings and rubber tires. The Company's
instruments measure the total thickness, basis weight and coating thickness of
web-type materials such as plastic foils, hot and cold metal strip, rubber,
glass and non-woven fabrics. The measuring technology incorporated in the
Company's products is based on partial absorption, reflection or change in
ionizing or infra-red radiation as well as of white light and laser beams, by
the materials to be measured. The Company's systems can measure a single point
on the material to be measured, several points or generate a "profile" of the
web. Measured values are acquired without contact and without interfering with
the production process, have high measurement accuracy and are extremely
reliable despite hostile environments. The Company offers its measuring gauges
with or without its process optimization systems. The customer's production
process can be regulated automatically by the Company's process optimization
system.

ON-LINE FINISHED MATERIALS QUALITY CONTROL SYSTEM

[DIAGRAM]

[This diagram depicts the Company's on-line finished materials quality control
system incorporated into a customer's hot dip galvanizing line. The diagram
contains a box depicting the customer's extrusion system. A sheet of web
material enters this box from the left (depicted by an arrow) and emerges at
the top of the box. Immediately after and above the box the material passes
through a hot gauge. The material continues through another box then turns
right over a roller and passes through another box entitled "Hot Dip
Galvanizing Line." It then turns downward over a roller and passes through a
mechanism entitled "Cold Gauges." The material then emerges through a series of
rollers out of the Cold Gauges to the right depicted by an arrow. Both the Hot
Gauge and the Cold Gauges are connected to a computer entitled "Expert System,"
depicting the flow of information from the gauges to the computer and then from
the computer to the line to regulate the thickness or coating thickness of the
material running through the line.]

The Company's products incorporate a variety of measurement gauges such as
x-ray thickness gauges, isotope thickness gauges, x-ray fluorescence coating
gauges or beta-backscatter gauges, depending on the application. One of the
Company's strengths is its proprietary know-how regarding application-specific
technology. The thickness gauges manufactured by the Company basically function
by measuring partial absorption of energy by the material to be measured. The
change in the intensity of the energy emitted is detected by application
specific sensors, then processed by high speed microprocessors, before emerging
as the measured value. These instruments can incorporate the Company's high
speed proprietary software to form a fully integrated process optimization
system for continuous manufacturing processes and improved product quality. The
Company's Fuzzy-Neurocontrol(TM) software provides predictive adaptive control
of the process. This proprietary software allows a more timely control of the
process, adapts the controls to the varying conditions in the process and offers
improved material savings. The Company's Spectracomp(TM) software automatically
and continuously compensates for variations in metal thickness measurements
resulting from changes in the composition of the alloy being measured.

Competitive pressures have necessitated that producers of web-type
materials reduce production costs. The Company's products not only save on raw
materials and energy but they also maximize productivity and product quality.
The total thickness of web-type material, or the coating on it, is measured
accurately at the point of manufacture by the Company's products and are
compared by the system with an input target value. Adjustments can be made to
the manufacturing process early in the process, thereby reducing material waste.
The Company's systems also provide several competitive advantages which afford
the customer additional cost savings. For example, the Company's products can
accurately measure materials closer to the edge of the strip thus reducing
material waste. The Company has developed a reputation for rugged and reliable
instruments that can withstand hostile conditions. Ruggedness is critical to
customers because the Company believes downtime of the production system could
cost a customer up to $100,000 an hour. The Company's proprietary hot gauges can
be placed closer to the actuator (air knife) than conventional cold gauges
allowing adjustments earlier in the production process thus decreasing material
waste. In addition, the Company's systems include an extremely short response
time gauge, sending control signals one inch(2.5 centimeters) after measurement,
while competitors' gauges typically require at least twice this distance. Costs
can also be reduced through reduced start-up and product change times using the
system's comprehensive organized display of the process parameters. Reducing
start-up times at the beginning of the production and product change saves
energy, reduces scrap and saves machine time. Depending on

25
27

the circumstances, most customers can recoup their investment in a Company
system within six to eighteen months of installation. Prices for the Company's
gauges and process optimization systems typically range from $50,000 to $1
million. Competitive technologies enabling on-line measurement of the thickness,
such as contacting mechanical thickness gauges and pneumatic calipers, exist,
however, the Company believes that use of these technologies results in inferior
accuracy when compared with its own products.

The Company believes there is significant market potential for its products
resulting from several factors including increased demand for on-line
optimization, growing market opportunities in Asia and Latin America, increased
market penetration in the U.S. and the expansion of steel minimills. The Company
estimates that there are currently several thousand production lines worldwide
that currently use or could benefit from on-line process optimization. Asia and
Latin America are experiencing growth in infrastructure development and
manufacturing capacity which will drive demand for the Company's systems. The
Company also believes there are potential opportunities to penetrate the U.S.
markets which are dominated by few competitors. End users in the U.S. are
demanding alternative sources of on-line process optimization. Increased
emphasis on energy efficiency will also create demand for the Company's
products. For example, in the automotive industry, for a given load-carrying
capacity, all types of vehicles are being designed with a lower mass, with the
objective of reducing energy consumption. This leads directly to several trends:
for example, mass-produced road vehicles will use less steel and be made of
thinner steels, plastic sheet parts and even aluminum. (The Audi A8, for example
has an aluminum body.) Likewise, aircraft parts will be fabricated from more
exotic materials such as composites and titanium. These trends indicate lower
volume but higher value manufacture of web-type products and, consequently,
increased demand for the Company's gauges and process optimization systems. The
expansion of steel minimills (recycling) has created competitive pressures in
the steel industry through increased demand for efficiency, which in turn will
also stimulate demand for the Company's gauges and process optimization systems.

COMPETITION

In the coal, cement and mineral industries, the Company competes primarily
on performance and to a lesser extent on price. Competition regarding on-line
coal and cement analyzers is limited at present. Scantech Limited (formerly
Mineral Control Instrumentation Ltd.) of Australia is the Company's principal
competitor in the on-line coal analyzer market. Scantech Limited, which entered
the cement industry market in 1993, is also the Company's principal competitor
in this industry. The Company is a recent entrant into the on-line mineral
slurry analyzers market where it competes primarily with Amdel of Australia. The
market for solids and multiphase analyzers for process control generally is
fragmented, with numerous competitors. The Company believes it is a market
leader in the segment of the solids and multiphase analyzer market for on-line
bulk materials analyzers using neutron interrogation.

Competition in the thickness gauging business is highly fragmented with
numerous competitors competing in various end use market segments. As a result,
competition varies according to the end use segment. The Company competes by
quality, performance and price. The Company's largest competitor is Honeywell,
through its recent acquisition of Measurex (USA), which in turn recently
acquired Data Measurement Corporation, the metals gauging division of Loral and
Ohmart. Both Data Measurement and Loral offer systems to the metals industry.
Ohmart is a supplier mainly to the plastics industry. Toshiba and Yokoyawa
(Japan) are at present competing with the Company in Asia. IMS (Germany) and IRM
(Belgium/USA), (formerly the metal gauging division of ABB (Sweden/Switzerland))
compete with the Company worldwide in the metals industry. There are a number of
competitors such as NDC (US), Eurotherm (UK) and Infrared Engineering (UK) which
compete with the Company in the plastics and rubber industry.

Certain of the Company's competitors have greater resources, manufacturing
and marketing capabilities, technical staff and production facilities than those
of the Company. As a result, they may be able to adapt more quickly to new or
emerging technologies and changes in customer requirements, or to devote greater
resources to the promotion and sale of their products than can the Company.
Further,

26
28

competition with respect to all of the Company's products could increase if new
companies enter the market or if existing competitors expand their product
lines. There can be no assurance that competitors of the Company will not
develop technological innovations that will render products of the Company
obsolete.

MARKETING, SALES AND DISTRIBUTION

On-line Raw Materials Analyzer Business. The Company sells its on-line raw
material analyzer products directly to its customers worldwide through its sales
force consisting of 11 persons. The territories of this sales force are
primarily geographical with some segment specialization. In addition, the
Company uses a network of sales and service representatives in 23 countries
around the world to facilitate product distribution worldwide. The primary
function of these representatives is to stay in close contact with customers or
potential customers, gather market information, translate, advertise,
participate in trade shows, arrange meetings and facilitate logistics. The
Company also sells some products to original equipment manufacturers ("OEMs")
who offer the Company's products along with their own or a third party's
products. Sales to OEMs represent approximately 10% of the Company's total
revenues.

On-line Finished Materials Quality Control Business. The Company sells its
on-line finished materials quality control systems primarily in Europe through a
direct sales force of 20 employees, and through a network of 14 distributors and
sales representatives in Europe. In Asia, a sales network is being established
with three agents currently under contract covering China, India and Japan.
Recently, the Company has employed three agents in Latin America covering
Argentina, Brazil and Colombia. In November 1996, an area sales manager was
hired to establish a sales operation addressing countries participating in
NAFTA. In addition, the Company sells its products to OEMs. Sales to OEMs
represented approximately one-third of the Company's total revenues from its
on-line finished materials quality control business for 1996. The Company
intends to further extend its sales network in Asia, North America and Latin
America.

Customer Service and Support. The Company believes that high quality
customer service and support is critical to success in the process optimization
segment of the analytical instrumentation industry. The Company maintains a
staff of engineers to assist customers with installing and integrating their
process optimization system and to provide ongoing spare parts and calibration
services for its on-line raw materials analyzer business. In addition, modems
permit remote diagnostics by customer support personnel from the Company's
headquarters or from satellite support centers. The Company supports its
manufacturing operations for its on-line finished materials quality control
business with a full range of services including application and engineering
support, installation, supervision, commissioning, emergency field service by
remote diagnostics via modems, extensive customer training, consulting and spare
parts.

RESEARCH AND DEVELOPMENT

The Company maintains active programs for the development and introduction
of new products and improvements to existing products. The Company also seeks to
develop new applications for its existing products and technology. In
particular, the Company is actively seeking new applications for its non-
invasive, non-destructive analysis technologies. The Company is also in the
process of developing other applications for its CBA.

With respect to its on-line finished materials quality control business,
the Company is focused on two areas of commercial importance in the metals
industry, the measurement of metal coatings and the cross-profile thickness
measurement of hot steel strip, cold strip and plate. In both areas of
measurement, parameters, particularly accuracy and resolution, are being
tightened in response to end-user needs. In addition, the Company is involved in
numerous other development projects including, among others, development of an
x-ray based tomographic thickness profile system. The object of this system is
to take a snapshot of thickness variations across the sheet at a high transverse
resolution. This system is in the early stages of development. The Company is
also developing a compact fixed energy x-ray source for

27
29

thin films in the plastic, rubber, glass and other industries which the Company
anticipates introducing to the market in 1997.

Research and development expenses for the Company were $2.3 million, $2.6
million, $3.0 million and $1.0 million in fiscal 1994, 1995 and 1996, and the
three months ended March 29, 1997, respectively. As of March 29, 1997, the
Company had 32 full time employees engaged in research and development.

PATENTS

The Company's policy is to protect its intellectual property rights and to
apply for patent protection when appropriate. The Company is the owner of 11
United States patents as well as corresponding foreign patents having expiration
dates ranging from 1998 through 2012. Patent protection is believed to provide
the Company with competitive advantages with respect to certain instruments. The
Company also considers that technical know-how, trade secrets and trademarks are
important to its business.

There can be no assurance that any patents now or hereafter owned by the
Company will afford protection against competitors. Proceedings initiated by the
Company to protect its proprietary rights could result in substantial costs to
the Company. There can be no assurance that competitors of the Company, some of
whom have substantially greater resources than those of the Company, will not
initiate litigation to challenge the validity of the Company's patents, use
their resources to design comparable products that do not infringe the Company's
patents or initiate claims that the Company's products infringe the competitors'
patents. The Company could incur substantial costs and diversion of management
resources with respect to the defense of any such challenges or claims, which
could have a material adverse effect on the Company's business, financial
condition, and results of operation. Furthermore, parties making such challenges
or claims could secure a judgment awarding substantial damages, as well as
injunctive or other equitable relief, which could effectively block the
Company's ability to make, use, sell, distribute or market its products and
services in the U.S. and abroad. See "Risk Factors -- Proprietary Rights."

FACILITIES

The Company's various businesses are operated from separate facilities. The
Company leases approximately 45,000 square feet in San Diego, California
pursuant to a lease that expires in 2003. The Company uses this facility for
manufacturing, sales and administration for its on-line raw materials analyzer
business. The Company also leases approximately 20,000 square feet in
Gloucester, England, pursuant to a lease expiring in 2001, and owns an
approximately 100,000 square foot facility in Erlangen, Germany, of which
approximately 45,300 square feet are utilized by the Company, with the balance
being used by another Thermo Instrument company. Both of these facilities are
used by the Company for manufacturing, sales and administration for its on-line
finished materials quality control business. In addition, the Company leases
office space throughout the world for its sales and service operations. The
Company believes that these facilities are adequate for its present operations.

PERSONNEL

As of March 29, 1997, the Company had a total of 317 employees, of whom 51
were engaged in research and product development and 266 were engaged in sales,
service, manufacturing and general management. The Company has had no work
stoppages and considers its relations with employees to be good.

BACKLOG

The Company's backlog of firm orders was approximately $26.5 million at
March 30, 1996 and March 29, 1997. The Company includes in backlog only those
orders for which it has received firm purchase orders and for which delivery has
been specified within twelve months. Because of the possibility of customer
changes in delivery schedules, cancellation of orders and potential delays in
product shipments, the Company's backlog as of any particular date may not be
representative of actual sales for any succeeding period.

28
30

RAW MATERIALS

Various components of the Company's products are supplied by sole-source
vendors. The Company has not experienced significant difficulty in obtaining
adequate supplies from these vendors, and has identified alternate suppliers.
However, there can be no assurance that the unanticipated loss of a single
vendor would not result in delays in shipments or the introduction of new
products.

SEASONALITY

The Company's on-line finished materials quality control business
experiences a slowdown in revenues during the first quarter of each calendar
year primarily because its customers tend to place their orders earlier in the
year so that they can have the systems installed either during the holiday
season in the third quarter or between Christmas and the New Year.

LEGAL PROCEEDINGS

The Company is not a party to any litigation that it believes could
reasonably be expected to have a material adverse effect on the Company or its
results of operations.

RELATIONSHIP WITH THERMO ELECTRON
AND THERMO INSTRUMENT

Thermo Electron has adopted a strategy of selling a minority interest in
subsidiary companies to outside investors as an important tool in its future
development. As part of this strategy, Thermo Instrument has created the Company
as a privately held subsidiary, and Thermo Instrument and Thermo Electron, and
certain of their subsidiaries, have created several other privately and publicly
held majority-owned subsidiaries. From time to time, Thermo Electron and its
subsidiaries will create other majority-owned subsidiaries as part of its
spin-out strategy. (The Company and the other Thermo Electron subsidiaries are
hereinafter referred to as the "Thermo Subsidiaries.")

Thermo Instrument develops, manufactures, and markets analytical
instruments used to detect and monitor air pollution, radioactivity, complex
chemical compounds and toxic metals and other elements in a broad range of
liquids and solids. For its fiscal year ended December 30, 1995 and December 28,
1996 and the three months ended March 29, 1997, Thermo Instrument had
consolidated revenues of $782,662,000, $1,209,362,000 and $329,120,000,
respectively, and consolidated net income of $79,306,000, $132,751,000 and
$33,587,000, respectively.

Thermo Electron and its subsidiaries develop, manufacture and market
environmental monitoring and analysis instruments and manufacture biomedical
products including heart-assist devices and mammography systems, papermaking and
recycling equipment, alternative-energy systems and other specialized products
and technologies. Thermo Electron and its subsidiaries also provide
environmental and metallurgical services and conduct advanced technology
research and development. For its fiscal year ended December 30, 1995 and
December 28, 1996 and the three months ended March 29, 1997, Thermo Electron had
consolidated revenues of $2,270,291,000, $2,932,558,000 and $763,505,000,
respectively, and consolidated net income of $139,582,000, $190,816,000 and
$52,058,000, respectively.

THE THERMO ELECTRON CORPORATE CHARTER

Thermo Electron and the Thermo Subsidiaries, including the Company,
recognize that the benefits and support that derive from their affiliation are
essential elements of their individual performance. Accordingly, Thermo Electron
and each of the Thermo Subsidiaries adopted the Thermo Electron Corporate
Charter (the "Charter") to define the relationships and delineate the nature of
such cooperation among themselves. The purpose of the Charter is to ensure that
(1) all of the companies and their stockholders are treated consistently and
fairly, (2) the scope and nature of the cooperation among the companies, and
each company's responsibilities, are adequately defined, (3) each company has
access to the combined resources and financial, managerial and technological
strengths of the

29
31

others, and (4) Thermo Electron and the Thermo Subsidiaries, in the aggregate,
are able to obtain the most favorable terms from outside parties.

To achieve these ends, the Charter identifies the general principles to be
followed by the companies, addresses the role and responsibilities of the
management of each company, provides for the sharing of group resources by the
companies and provides for centralized administrative, banking and credit
services to be performed by Thermo Electron. The services provided by Thermo
Electron include collecting and managing cash generated by members, coordinating
the access of Thermo Electron and the Thermo Subsidiaries (the "Thermo Group")
to external financing sources, ensuring compliance with external financial
covenants and internal financial policies, assisting in the formulation of
long-range planning and providing other banking and credit services. Pursuant to
the Charter, Thermo Electron may also provide guarantees of debt obligations of
the Thermo Subsidiaries or may obtain external financing at the parent level for
the benefit of the Thermo Subsidiaries. In certain instances, the Thermo
Subsidiaries may provide credit support to, or on behalf of, the consolidated
entity or may obtain financing directly from external financing sources. Under
the Charter, Thermo Electron is responsible for determining that the Thermo
Group remains in compliance with all covenants imposed by external financing
sources, including covenants related to borrowings of Thermo Electron or other
members of the Thermo Group, and for apportioning such constraints within the
Thermo Group. In addition, Thermo Electron is also responsible for ensuring that
members comply with internal policies and procedures. The cost of the services
provided by Thermo Electron to the Thermo Subsidiaries is covered under existing
corporate services agreements between Thermo Electron and each of the Thermo
Subsidiaries.

The Charter presently provides that it shall continue in effect so long as
Thermo Electron and at least one Thermo Subsidiary participates. The Charter may
be amended at any time by agreement of the participants. Any Thermo Subsidiary,
including the Company, can withdraw from participation in the Charter upon 30
days' prior notice. In addition, Thermo Electron may terminate a subsidiary's
participation in the Charter in the event the subsidiary ceases to be controlled
by Thermo Electron or ceases to comply with the Charter or the policies and
procedures applicable to the Thermo Group. A withdrawal from the Charter
automatically terminates the corporate services agreement in effect between the
withdrawing company and Thermo Electron. The withdrawal from participation does
not terminate outstanding commitments to third parties made by the withdrawing
company, or by Thermo Electron or other members of the Thermo Group, prior to
the withdrawal. However, a withdrawing company is required to continue to comply
with all policies and procedures applicable to the Thermo Group and to provide
certain administrative functions mandated by Thermo Electron so long as the
withdrawing company is controlled by or affiliated with Thermo Electron.

CORPORATE SERVICES AGREEMENT

As provided in the Charter, the Company and Thermo Electron have entered
into a Corporate Services Agreement (the "Services Agreement") under which
Thermo Electron's corporate staff provides certain administrative services,
including certain legal advice and services, risk management, certain employee
benefit administration, tax advice and preparation of tax returns, centralized
cash management and certain financial and other services to the Company. The
annual fee for these services was equal to 1.2% of the Company's revenues for
calendar 1995. Beginning January 1, 1996, the fee was reduced to 1% of the
Company's revenues. The fee is reviewed annually and may be changed by mutual
agreement of the Company and Thermo Electron. During fiscal 1995 and 1996,
Thermo Electron assessed the Company fees of $552,000 and $520,000,
respectively.

Management believes that the service fees charged under the Services
Agreement are reasonable and that the terms of the Services Agreement are fair
to the Company. For items such as employee benefit plans, insurance coverage and
other identifiable costs, Thermo Electron charges the Company based on charges
directly attributable to the Company. The Services Agreement automatically
renews for successive one-year terms, unless canceled by the Company upon 30
days' prior written notice. In addition, the Services Agreement terminates
automatically in the event the Company ceases to be a member of the Thermo Group
or ceases to be a participant in the Charter. In the event of a termination of

30
32

the Services Agreement, the Company will be required to pay a termination fee
equal to the fee that was paid by the Company for services under the Services
Agreement for the nine-month period prior to termination. Following termination,
Thermo Electron may provide certain administrative services on an as-requested
basis by the Company or as required in order to meet the Company's obligations
under Thermo Electron's policies and procedures. Thermo Electron will charge the
Company a fee equal to the market rate for comparable services if such services
are provided following termination.

TAX ALLOCATION AGREEMENT

The Tax Allocation Agreement between the Company and Thermo Electron
outlines the terms under which the Company is to be included in Thermo
Electron's consolidated Federal and state income tax returns. Under current law,
the Company will be included in such tax returns so long as Thermo Instrument
owns at least 80% of the Company's outstanding Common Stock and Thermo Electron
owns at least 80% of Thermo Instrument's outstanding common stock. In years in
which the Company has taxable income it will pay to Thermo Electron amounts
comparable to the taxes it would have paid if it had filed its own separate
company tax returns. Immediately following this offering, Thermo Instrument will
own less than 80% of the Company's outstanding Common Stock and the Company will
not be included in Thermo Electron's consolidated Federal and state income tax
returns for periods commencing thereafter and will be required to file its own
tax returns.

MASTER GUARANTEE REIMBURSEMENT AGREEMENTS

The Company has entered into a Master Guarantee Reimbursement Agreement
with Thermo Electron which provides that the Company will reimburse Thermo
Electron for any costs it incurs in the event it is required to pay third
parties pursuant to any guarantees it issues on the Company's behalf. Thermo
Instrument has entered into a similar agreement with Thermo Electron with regard
to the Company's obligations which are guaranteed by Thermo Electron. The
Company has also entered into a Master Guarantee Reimbursement Agreement with
Thermo Instrument which provides that the Company will reimburse Thermo
Instrument for any costs it incurs in the event that Thermo Instrument is
required to pay Thermo Electron or any other party pursuant to any guarantees it
issues on the Company's behalf.

MISCELLANEOUS

As of March 29, 1997, $15,549,000 of the Company's cash equivalents were
invested in a repurchase agreement with Thermo Electron. Under this agreement,
the Company in effect lends excess cash to Thermo Electron which Thermo Electron
collateralizes with investments principally consisting of corporate notes,
United States government agency securities, money market funds, commercial
paper, and other marketable securities, in the amount of at least 103% of such
obligation. The Company's funds subject to the repurchase agreement will be
readily convertible into cash by the Company. The repurchase agreement earns a
rate based on the 90-day Commercial Paper Composite Rate plus 25 basis points,
set at the beginning of each quarter.

The Company leases approximately 54,700 square feet of its 100,000 square
foot facility in Erlangen, Germany on a month-to-month basis to another Thermo
Instrument company. The Thermo Instrument company is responsible for paying to
the Company its pro rata share of occupancy expenses, including utilities and
taxes, associated with the facility which payments in 1996 amounted to $368,000
in the aggregate.

The Company has borrowed funds from a wholly owned subsidiary of Thermo
Optek Corporation ("Thermo Optek"), a majority-owned subsidiary of Thermo
Instrument, pursuant to certain promissory notes. The Company had $1,388,000 and
$1,928,000 outstanding under the promissory notes at year-end 1995 and 1996,
respectively. The notes bear interest at a variable rate. The interest rate for
the notes outstanding at year-end 1995 and 1996 was 4.6% and 3.8%, respectively.
The notes were repaid in February 1997. In addition, the Company had $3,617,000
and $2,611,000 of noninterest-bearing advances from Thermo Instrument and
affiliated companies at year-end 1995 and 1996, respectively,

31
33

which were due on demand. In December 1996, the Company borrowed $2,778,000
pursuant to a noninterest-bearing advance from a wholly owned subsidiary of
Thermo Instrument, which was repaid on January 15, 1997. At March 29, 1997, the
Company had $194,000 of noninterest-bearing receivables from Thermo Instrument
and affiliated companies, which are due on demand.

In 1996, the Company paid a ten percent (10%) commission totaling $69,670
to Thermo Sentron Inc., a majority-owned subsidiary of Thermedics Inc., which is
in turn a majority-owned subsidiary of Thermo Electron, for assisting in the
sale by the Company of its products in Australia.

In the first quarter of 1997, the Company purchased several x-ray source
components for $75,000 from Kevex X-Ray Inc., a wholly owned subsidiary of
ThermoSpectra Corporation, which in turn is a majority-owned subsidiary of
Thermo Instrument.

Directors Deferred Compensation Plan. Under the Company's Deferred
Compensation Plan for Directors (the "Deferred Compensation Plan"), a Director
has the right to defer receipt of his fees until he ceases to serve as a
Director, dies or retires from his principal occupation. In the event of a
change in control or proposed change in control of the Company that is not
approved by the Board of Directors, deferred amounts become payable immediately.
Either of the following is deemed to be a change of control: (a) the occurrence,
without the prior approval of the Board of Directors, of the acquisition,
directly or indirectly, by any person of 50% or more of the outstanding Common
Stock or the outstanding common stock of Thermo Instrument or 25% or more of the

be disbursed solely in shares of Common Stock accumulated under the Deferred
Compensation Plan. As of May 27, 1997, the Company has reserved 12,500 shares
under this plan. The Deferred Compensation Plan will not become effective until
completion of an initial public offering. No stock options have been granted
under this plan.

approve an allocation of a percentage of annual compensation (salary and
bonus) for the time he devotes to the affairs of the Company. For 1996, none
of Mr. Helm's annual compensation was allocated to the Company. In addition,
Mr. Helm has been granted options to purchase common stock of Thermo
Electron and certain of its subsidiaries other than the Company from time to
time by Thermo Electron or such other subsidiaries. These options are not
reported here as they were granted as compensation for service to Thermo
Electron companies in capacities other than in his capacity as Chief
Executive Officer of the Company.

The following table sets forth information concerning individual grants of
stock options made during fiscal 1996 to the Company's chief executive officer

(1) All options to purchase shares of the Common Stock of the Company
(designated in the table as MKA) were granted after the end of fiscal 1996
but are included in the table for clarity of presentation. All of the
options granted during the fiscal year are immediately exercisable, except
the options to purchase shares of the Common Stock of the Company, which are
not exercisable until the earlier of (i) 90 days after the effective date of
the registration of the Company's Common Stock under Section 12 of the
Securities Exchange Act of 1934 and (ii) nine years after the grant date. In
all cases, the shares acquired upon exercise are subject to repurchase by
the granting corporation at the exercise price if the optionee ceases to be
employed by such corporation or another Thermo Electron company. The
granting corporation may exercise its repurchase rights within six months
after the termination of the optionee's employment. For publicly traded
companies, the repurchase rights generally lapse ratably over a five- to
ten-year period, depending on the option term which may vary from seven to
twelve years, provided that the optionee continues to be employed by the
granting corporation or another Thermo Electron company. For companies that
are not publicly traded, the repurchase rights lapse in their entirety on
the ninth anniversary of the grant

36
38

date. The granting corporation may permit the holders of all such options to
exercise options and satisfy tax withholding obligations by surrendering
shares equal in fair market value to the exercise price or withholding
obligation.

(2) The amounts shown on this table represent hypothetical gains that could be
achieved for the respective options if exercised at the end of the option
term. These gains are based on assumed rates of stock appreciation of 5% and
10%, compounded annually from the date the respective options were granted
to their expiration date. The gains shown are net of the option exercise
price, but do not include deductions for taxes or other expenses associated
with the exercise. Actual gains, if any, on stock option exercises will
depend on the future performance of the Common Stock, the option holders'
continued employment through the option period and the date on which the
options are exercised.

(3) Mr. Helm has been granted options to purchase shares of the common stock of
Thermo Electron and its subsidiaries other than the Company. These options
are not reported in the table as they were granted as compensation for
service in capacities other than Mr. Helm's capacity as Chief Executive
Officer of the Company.

(4) These options were granted under stock option plans maintained by Thermo
Electron companies other than the Company and accordingly are reported as a
percentage of total options granted to employees of Thermo Electron and its
subsidiaries.

(1) All options to purchase shares of the Common Stock of the Company were
granted after the end of fiscal 1996 but are included in the table for
clarity of presentation. All of the options reported outstanding at the end
of the fiscal year were immediately exercisable, except for options to
purchase shares of the common stock of the Company which are not exercisable
until the earlier of (i) 90 days after the effective date of the
registration of such company's common stock under Section 12 of the
Securities Exchange Act and (ii) nine years after the grant date. In all
cases, the shares acquired upon exercise of the options reported in the
table are subject to repurchase by the granting corporation at the exercise
price if the optionee ceases to be employed by such corporation

or another Thermo Electron company. The granting corporation may exercise
its repurchase rights within six months after the termination of the
optionee's employment. For publicly traded companies, the repurchase rights
generally lapse ratably over a five- to ten-year period, depending on the
option term which may vary from seven to twelve years, provided that the
optionee continues to be employed by the granting corporation or another
Thermo Electron company. For companies whose shares are not publicly traded,
the repurchase rights lapse in their entirety on the ninth anniversary of
the grant date.

(2) Mr. Helm has been granted options to purchase shares of the common stock of
Thermo Electron and its subsidiaries other than the Company. These options
are not reported here as they were granted as compensation for service to
other Thermo Electron companies in capacities other than in Mr. Helm's
capacity as Chief Executive Officer of the Company.

(3) No public market existed for the shares underlying these options as of May
27, 1997. Accordingly, no value in excess of exercise price has been
attributed to these options.

DESCRIPTION OF CAPITAL STOCK

As of March 29, 1997, the Company had 25,000,000 shares of Common Stock
authorized for issuance, of which 5,967,833 were issued and outstanding. As of
March 29, 1997, there were approximately 82 beneficial owners of Common Stock.
Each share of Common Stock is entitled to pro rata participation in
distributions upon liquidation and to one vote on all matters submitted to a
vote of stockholders. Dividends may be paid to the holders of Common Stock when
and if declared by the Board of Directors out of funds legally available
therefor. Holders of Common Stock have no preemptive or similar rights. The
outstanding shares of Common Stock are, and the shares offered hereby when
issued will be, legally issued, fully paid and nonassessable.

The shares of Common Stock have noncumulative voting rights, which means
that the holders of more than 50% of the shares voting can elect all the
Directors if they so choose, and in such event, the holders of the remaining
shares cannot elect any Directors. Prior to this offering, Thermo Instrument
owned 5,000,000 shares of Common Stock, which represented 84% of the outstanding
Common Stock. Upon completion of this Offering, Thermo Instrument (and Thermo
Electron through its majority ownership of Thermo Instrument) will continue to
beneficially own at least 63% of the outstanding Common Stock, and will have the
power to elect all of the members of the Company's Board of Directors.

In May 1997, the Company declared and effected a one-for-two reverse stock
split pursuant to an amendment to its Certificate of Incorporation filed with
the Delaware Secretary of State on May 27, 1997. As a result, each share of
Common Stock outstanding immediately prior to such split was automatically
converted into one-half of a share of Common Stock. No fractional shares of
Common Stock were issued upon effectiveness of such split and all shareholders
otherwise entitled to fractional shares are entitled to cash in lieu of such
fractional share in the sum of such fractional share multiplied by $15.00. The
Company adopted this reverse stock split in order to enhance the marketability
of the Common Stock offered hereby.

The Company's Certificate of Incorporation contains certain provisions
permitted under the General Corporation Law of Delaware relating to the
liability of Directors. The provisions eliminate a Director's liability for
monetary damages for a breach of fiduciary duty to the fullest extent permitted
by the General Corporation Law of Delaware. The Company's Certificate of
Incorporation also contains provisions to indemnify the Directors and officers
of the Company to the fullest extent permitted by the General Corporation Law of
Delaware. The Company believes that these provisions will assist the Company in
attracting and retaining qualified individuals to serve as Directors and
officers.

The transfer agent and registrar for the Common Stock is American Stock
Transfer & Trust Company.

SHARES ELIGIBLE FOR FUTURE SALE

Upon completion of this offering, there will be 7,967,833 shares of Common
Stock of the Company outstanding (assuming no exercise of the Underwriters'
over-allotment option). The shares issued in this offering will be freely
tradable without restriction or further registration under the Securities Act,
except that any shares purchased by affiliates of the Company, as that term is
defined in Rule 144 under the Securities Act, may generally only be resold in
compliance with applicable provisions of Rule 144. The Company has agreed,
pursuant to a Stock Purchase Agreement with the shareholders of the Company
other than Thermo Instrument, to file a registration statement under the
Securities Act covering the sale of 967,833 shares of the Common Stock owned by
them (the "Registrable Shares") within 120 days of the closing of this offering.
All fees, costs and expenses of the registration of the Registrable Shares will
be paid by the Company. See "Risk Factors -- Shares Eligible for Sale After this
Offering."

Of such 7,967,833 outstanding shares, 5,000,000 will be owned by Thermo
Instrument. Thermo Instrument has agreed that, without the prior written consent
of the Representatives (as defined below under the caption "Underwriters"), it
will not offer, sell, grant any option to purchase or otherwise dispose of any
shares of the Common Stock within 180 days after the date of this Prospectus,
other than (i) shares of Common Stock to be sold to the Underwriters in this
offering, (ii) the issuance of options

40
42

and sales of shares of Common Stock pursuant to existing stock-based
compensation plans, and (iii) shares of Common Stock issuable upon the
conversion of securities outstanding on the date of this Prospectus. Upon
expiration of this lock-up agreement, Thermo Instrument may sell its shares of
Common Stock in an offering registered under the Securities Act or pursuant to
an exemption from such registration. So long as Thermo Instrument is able to
elect a majority of the Board of Directors it will be able to cause the Company
at any time to register under the Securities Act all or a portion of the Common
Stock owned by Thermo Instrument or its affiliates, in which case it would be
able to sell such shares without restriction upon effectiveness of the
registration statement. In general, under Rule 144 as currently in effect, a
person (or persons whose shares are aggregated) who has beneficially owned
restricted shares for at least one year is entitled to sell, within any
three-month period, a number of such shares that does not exceed the greater of
(i) 1% of the then outstanding shares of Common Stock or (ii) the average weekly
trading volume in the Common Stock during the four calendar weeks preceding the
date of the notice filed pursuant to Rule 144. Sales under Rule 144 are also
subject to certain manner of sale restrictions and notice requirements and to
the availability of current public information about the Company. In addition, a
person who is deemed an "affiliate" of the Company must comply with Rule 144 in
any sale of shares of Common Stock not covered by a registration statement
(except, in the case of registered shares acquired by the affiliate on the open
market, for the holding period requirement). A person (or person whose shares
are aggregated) who is not deemed an "affiliate" of the Company and who has
beneficially owned restricted shares for at least two years is entitled to sell
such shares under Rule 144(k) without regard to the volume, notice and other
limitations of Rule 144. In meeting the one and two year holding periods
described above, a holder of restricted shares can include the holding periods
of a prior owner who was not an affiliate.

The Company has reserved 312,500 shares for grants under its existing
stock-based compensation plans. As of May 27, 1997, the Company had options
outstanding to purchase up to 298,000 shares of Common Stock to its employees
and Directors at an exercise price of $15.00 per share. None of such options are
currently exercisable. Ninety days after the completion of the Company's initial
public offering, such options will become immediately exercisable, subject to
repurchase at the exercise price if the optionee ceases to be employed by the
Company. This repurchase right lapses ratably (on an annual basis) over a five
to ten year period depending upon the term of the option. As of May 27,1997, the
repurchase rights had not lapsed with respect to any shares issuable upon
exercise of outstanding options. The Company intends to file registration
statements under the Securities Act to register all shares of Common Stock
issuable under such plans. Shares covered by these registration statements will
be eligible for sale in the public market after the effective date of such
registration statements. Each of the Company, Thermo Instrument and Thermo
Electron has agreed that it will not offer, sell, or grant any option to
purchase or otherwise dispose of any shares of Common Stock (except for the
grant of options and the sale of shares of Common Stock pursuant to stock-based
compensation plans, sales to Thermo Instrument and the issuance of shares as
consideration for the acquisition of one or more businesses (provided that such
shares may not be resold prior to the expiration of 180 days after the date of
this Prospectus)) within 180 days after the date of this Prospectus, without the
prior consent of the Representatives of the Underwriters.

Prior to this offering there has been no public market for the Common
Stock. The effect, if any, of public sales or the availability of shares for
sale at prevailing market prices cannot be predicted. Nevertheless, sales of
substantial amounts of shares in the public market could adversely affect
prevailing market prices.

UNDERWRITING

Subject to the terms and conditions set forth in an Underwriting Agreement
by and among the Company and each of the Underwriters named below, for whom
Salomon Brothers Inc, Lehman Brothers Inc., Smith Barney Inc. and Cazenove & Co.
are acting as representatives (the "Representatives"), each of the Underwriters
has severally agreed to purchase from the Company the number of shares of Common
Stock set forth opposite its name in the table below:

Lehman Brothers Inc. .....................................................
Smith Barney Inc..........................................................
Cazenove & Co. ...........................................................

---------
Total........................................................... 2,000,000
=========

In the Underwriting Agreement, the several Underwriters have agreed,
subject to the terms and conditions set forth therein, to purchase all of the
shares of Common Stock offered hereby (other than those covered by the
over-allotment option described below) if any such shares of Common Stock are
purchased. In the event of a default by any Underwriter, the Underwriting
Agreement provides that, in certain circumstances, purchase commitments of the
non-defaulting Underwriters may be increased or the Underwriting Agreement may
be terminated. The Company has been advised by the Representatives that the
several Underwriters propose initially to offer such shares of Common Stock at
the public offering price set forth on the cover page of this Prospectus and to
certain dealers at such price less a concession not in excess of $ per
share. The Underwriters may allow, and such dealers may reallow, a concession
not in excess of $ per share to other dealers. After the initial offering,
the public offering price and such concessions may be changed.

The Company has granted to the Underwriters an option, exercisable during
the 30-day period after the date of this Prospectus, to purchase up to 300,000
additional shares of Common Stock, at the public offering price less the
underwriting discount set forth on the cover page of this Prospectus. The
Underwriters may exercise such option only to cover over-allotments in the sale
of the shares of Common Stock that the Underwriters have agreed to purchase. To
the extent that the Underwriters exercise such option, each Underwriter will
have a firm commitment, subject to certain conditions, to purchase a number of
option shares proportionate to such Underwriter's initial commitment.

The Company, Thermo Instrument and Thermo Electron have agreed that they
will not, without the prior written consent of Salomon Brothers Inc, offer, sell
or contract to sell, or otherwise dispose of, directly or indirectly, or
announce an offer of any shares of Common Stock, options or any securities
convertible into, or exchangeable for, shares of Common Stock during the 180-day
period following the date of this Prospectus; provided, however, that the
Company may issue and sell Common Stock pursuant to any stock option plan in
effect at the date of this Prospectus and the Company may issue Common Stock
issuable upon the conversion of securities outstanding on the date of this
Prospectus. Salomon Brothers Inc in its sole discretion may release any of the
shares subject to the lock-up at any time without notice.

The Underwriting Agreement provides that the Company will indemnify the
several Underwriters against certain liabilities, including liabilities under
the Securities Act, or contribute to payments the Underwriters may be required
to make in respect thereof.

Until the distribution of the Common Stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the Underwriters and
certain selling group members to bid for and

42
44

purchase shares of Common Stock. As an exception to these rules, the
Representatives are permitted to engage in certain transactions that stabilize
the price of the Common Stock. Such transactions may consist of bids or
purchases for the purpose of pegging, fixing or maintaining the price of the
Common Stock.

In addition, if the Representatives over-allot (i.e., if they sell more
shares of Common Stock than are set forth on the cover page of this Prospectus),
and thereby create a short position in the Common Stock in connection with this
offering, the Representatives may reduce that short position by purchasing
Common Stock in the open market. The Representatives also may elect to reduce
any short position by exercising all or part of the over-allotment option
described herein.

The Representatives also may impose a penalty bid on certain Underwriters
and selling group members. This means that if the Representatives purchase
shares of Common Stock in the open market to reduce the Underwriters' short
position or to stabilize the price of the Common Stock, they may reclaim the
amount of the selling concession from the Underwriters and selling group members
who sold those shares as part of this offering.

In general, purchases of a security for the purpose of stabilization to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of such purchases. The
imposition of a penalty bid might have an effect on the price of a security to
the extent that it were to discourage resales of the security by purchasers in
this offering.

Neither the Company nor any of the Underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the Common Stock. In addition, neither
the Company nor any of the Underwriters makes any representation that the
Representatives will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.

The Representatives have informed the Company that they do not intend to
confirm sales to any account over which they exercise discretionary authority.

Prior to this offering there has been no public market for the Common
Stock. The price to the public for the shares of Common Stock will be determined
through negotiations between the Company and the Representatives and will be
based on, among other things, the Company's financial and operating history and
condition, the prospects of the Company and its industry in general, the
management of the Company and the market prices of securities of companies
engaged in businesses similar to those of the Company. There can, however, be no
assurance that the prices at which the shares of Common Stock will sell in the
public market after this offering will not be lower than the price at which it
is sold by the Underwriters.

LEGAL OPINIONS

The validity of the issuance of the Common Stock offered hereby will be
passed upon for the Company by Seth H. Hoogasian, Esq., General Counsel of
Thermo Electron, Thermo Instrument and the Company, and certain legal matters

Massachusetts. Mr. Hoogasian owns or has the right to acquire 2,500 shares of

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Directors of Metrika Systems Corporation:

We have audited the accompanying consolidated balance sheet of Metrika
Systems Corporation (a Delaware corporation and 84%-owned subsidiary of Thermo
Instrument Systems Inc.) and subsidiaries as of December 30, 1995 and December
28, 1996, and the related consolidated statements of income, cash flows and
shareholders' investment for each of the three years in the period ended
December 28, 1996. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Metrika
Systems Corporation and subsidiaries as of December 30, 1995 and December 28,
1996, and the results of their operations and their cash flows for each of the
three years in the period ended December 28, 1996, in conformity with generally
accepted accounting principles.

METRIKA SYSTEMS CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

Metrika Systems (the "Company") develops, manufactures and markets on-line
industrial process optimization systems that employ proprietary ultra-high speed
advanced scientific measurement technologies for applications in raw materials
analysis and finished materials quality control. The Company manufactures
process optimization systems that provide real-time, non-destructive analysis of
the composition of raw materials in basic materials production processes,
including coal, cement and minerals. The Company also manufactures systems which
are used primarily to measure and control parameters such as material thickness,
coating thickness and coating weight in web-type materials, such as metal strip,
rubber and plastic foils. Customers use these systems to improve product quality
and consistency, lower material costs, reduce energy consumption and minimize
waste.

Relationship with Thermo Instrument Systems Inc. and Thermo Electron
Corporation

The accompanying financial statements include the assets, liabilities,
income and expenses of the Company as included in Thermo Instrument's
consolidated financial statements. The accompanying financial statements do not
include Thermo Instrument's general corporate debt, which is used to finance
operations of all of its respective business segments, or an allocation of
Thermo Instrument's interest expense. The Company had positive cash flow from
operations for all periods presented.

Principles of Consolidation

The accompanying financial statements include the accounts of the Company
and its wholly owned subsidiaries. All material intercompany accounts and
transactions have been eliminated.

Fiscal Year

The Company has adopted a fiscal year ending the Saturday nearest December
31. References to 1994, 1995 and 1996 are for the fiscal years ended December
31, 1994, December 30, 1995 and December 28, 1996, respectively.

Revenue Recognition

Generally, the Company recognizes product revenues upon shipment of its
products. The Company provides a reserve for its estimate of warranty and
installation costs at the time of shipment. Revenues and profits on contracts
which due to their complexity extend over multiple quarterly reporting periods
are recognized using the percentage-of-completion method. Such contracts include
all manufacturing contracts of the Company's on-line finished materials quality
control business which commonly are of 5-10 months duration as well as certain
contracts of similar duration or longer at the Company's on-line raw materials
analyzer business. Revenues recorded under the percentage-of-completion method
were $14,884,000 in 1994, $17,523,000 in 1995 and $18,611,000 in 1996. The
percentage of completion is determined by relating the actual costs incurred to
date to management's estimate of total costs to be incurred on each contract. If
a loss is indicated on any contract in process, a provision is made currently
for the entire loss. Contracts generally provide for the billing of customers
upon the attainment of certain

F-7
53

METRIKA SYSTEMS CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

milestones in each contract. Revenues earned on contracts in process in excess
of billings are classified as unbilled contract costs and fees in the
accompanying balance sheet. There are no significant amounts included in the
accompanying balance sheet that are not expected to be recovered from existing
contracts at current contract values, or that are not expected to be collected
within one year, including amounts that are billed but not paid under retainage
provisions.

Stock-based Compensation Plans

The Company applies Accounting Principles Board Opinion ("APB") No. 25,
"Accounting for Stock Issued to Employees" and related interpretations in
accounting for its stock-based compensation plans (Note 2). Accordingly, no
accounting recognition is given to stock options granted at fair market value
until they are exercised. Upon exercise, net proceeds, including tax benefits
realized, are credited to equity.

Income Taxes

The Company, Thermo Instrument and Thermo Electron entered into a tax
allocation agreement under which the Company and Thermo Instrument are included
in Thermo Electron's consolidated federal and certain state income tax returns.
The agreement provides that in years in which the Company has taxable income, it
will pay to Thermo Electron amounts comparable to the taxes the Company would
have paid if it had filed separate tax returns. Upon completion of the proposed
initial public offering, Thermo Instrument's ownership of the Company will drop
below 80% and the Company will be required to file its own federal income tax
return.

In accordance with Statement of Financial Accounting Standards ("SFAS") No.
109, "Accounting for Income Taxes," the Company recognizes deferred income taxes
based on the expected future tax consequences of differences between the
financial statement basis and the tax basis of assets and liabilities,
calculated using enacted tax rates in effect for the year in which the
differences are expected to be reflected in the tax return.

Earnings per Share

Pursuant to certain Securities and Exchange Commission requirements,
earnings per share have been presented for all periods. Weighted average shares
for all periods represent the 5,000,000 shares issued to Thermo Instrument in
connection with the initial capitalization of the Company, and in 1996 the
effect of shares sold through a private placement, as well as the effect of the
assumed issuance of private placement shares and the assumed exercise of stock
options issued within one year prior to the Company's proposed initial public
offering in all periods.

Cash and Cash Equivalents

Prior to its incorporation, the cash receipts and disbursements of the
Company's domestic operations were combined with other Thermo Instrument
corporate cash transactions and balances. Therefore, cash of the Company's
domestic operations through November 1996 is not included in the accompanying
balance sheet.

As of December 28, 1996, $15,672,000 of the Company's cash equivalents were
invested in a repurchase agreement with Thermo Electron. Under this agreement,
the Company in effect lends excess cash to Thermo Electron, which Thermo
Electron collateralizes with investments principally consisting of U.S.
government agency securities, corporate notes, commercial paper, money market
funds and other marketable securities, in the amount of at least 103% of such
obligation. The Company's funds subject to the repurchase agreement are readily
convertible into cash by the Company and have an original maturity of three
months or less. The repurchase agreement earns a rate based on the 90-day
Commercial Paper Composite Rate plus 25 basis points, set at the beginning of
each quarter. Cash equivalents of $978,000 and $4,443,000 at year-end 1995 and
1996, respectively, at the Company's foreign operations were

F-8
54

METRIKA SYSTEMS CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

invested in interest-bearing accounts. Cash and cash equivalents are carried at
cost, which approximates market value.

Inventories

Inventories are stated at the lower of cost (on a weighted average basis)
or market value and include materials, labor and manufacturing overhead. The
components of inventories are as follows:

1995 1996
------ ------
(IN THOUSANDS)

Raw material and supplies.............................. $3,289 $4,207
Work in process........................................ 2,045 1,230
Finished goods......................................... 342 910
------ ------
$5,676 $6,347
====== ======

Property, Plant and Equipment

The costs of additions and improvements are capitalized, while maintenance
and repairs are charged to expense as incurred. The Company provides for
depreciation and amortization using the straight-line method over the estimated
useful lives of the property as follows: buildings, 40 years; machinery and
equipment, 3 to 10 years; and leasehold improvements, the shorter of the term of
the lease or the life of the asset. Property, plant and equipment consists of
the following:

1995 1996
------- -------
(IN THOUSANDS)

Land................................................. $ 2,011 $ 1,861
Buildings............................................ 9,286 8,594
Machinery, equipment and leasehold improvements...... 5,108 5,501
------- -------
16,405 15,956
Less: Accumulated depreciation and amortization...... 2,878 3,856
------- -------
$13,527 $12,100
======= =======

Other Assets

Other assets in the accompanying balance sheet consists primarily of
acquired technology and the cost of acquired patents that are being amortized
using the straight-line method over their estimated useful lives, ranging from 5
to 20 years. Accumulated amortization was $705,000 and $925,000 at year-end 1995
and 1996, respectively.

Cost in Excess of Net Assets of Acquired Companies

The excess of cost over the fair value of net assets of acquired companies
is amortized using the straight-line method over 40 years. Accumulated
amortization was $1,196,000 and $1,627,000 at year-end 1995 and 1996,
respectively. The Company assesses the future useful life of this asset whenever
events or changes in circumstances indicate that the current useful life has
diminished. The Company considers the future undiscounted cash flows of the
acquired companies in assessing the recoverability of this asset. If impairment
has occurred, any excess of carrying value over fair value is recorded as a
loss.

Foreign Currency

All assets and liabilities of the Company's foreign subsidiaries are
translated at year-end exchange rates, and revenues and expenses are translated
at average exchange rates for the year, in accordance with SFAS No. 52, "Foreign
Currency Translation." Resulting translation adjustments are reflected as a
separate component of shareholders' investment titled "Cumulative translation
adjustment." Foreign

F-9
55

METRIKA SYSTEMS CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

currency transaction gains and losses are included in the accompanying statement
of income and are not material for the three years presented.

Fair Value of Financial Instruments

The Company's financial instruments consist primarily of cash and cash
equivalents, accounts receivable, notes payable and current maturities of
long-term obligation, accounts payable, due to parent company and affiliated
companies and long-term obligation. The Company's long-term obligation bears
interest at a variable market rate and therefore, the carrying amount
approximates fair value (Note 6). The carrying amounts of the Company's
remaining financial instruments approximate fair value due to their short-term
nature.

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,
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

Interim Financial Statements

The financial statements as of March 29, 1997 and for the three-month
periods ended March 30, 1996 and March 29, 1997, are unaudited but, in the
opinion of management, reflect all adjustments of a normal recurring nature
necessary for a fair presentation of results for these interim periods. The
results of operations for the three-month period ended March 29, 1997 are not
necessarily indicative of the results to be expected for the entire year.

2. EMPLOYEE BENEFIT PLANS

Stock-based Compensation Plans

Stock Option Plans

In November 1996, the Company adopted a stock-based compensation plan for
its key employees, directors, and others, which permits the grant of stock and
stock-based awards as determined by the human resources committee of the
Company's Board of Directors (the "Board Committee"), including restricted
stock, stock options, stock bonus shares or performance-based shares. The option
recipients and the terms of options granted under this plan are determined by
the Board Committee. Options granted generally vest and become immediately
exercisable on the ninth anniversary of the grant date, unless the Company's
common stock becomes publicly traded prior to such date. In such an event,
options become exercisable 90 days after the Company becomes subject to the
Securities Exchange Act of 1934, but will be subject to certain transfer
restrictions and the right of the Company to repurchase shares issued upon
exercise of the options at the exercise price, upon certain events. The
restrictions and repurchase rights generally will be deemed to have lapsed
ratably over periods ranging from five to ten years after the first anniversary
of the grant date, depending on the term of the option, which generally ranges
from ten to twelve years. Nonqualified stock options may be granted at any price
determined by the Board Committee, although incentive stock options must be
granted at not less than the fair market value of the Company's stock on the
date of grant. As of March 31, 1997, no options have been granted under this
plan. In addition to the Company's stock-based compensation plans, certain
officers and key employees may also participate in the stock-based compensation
plans of Thermo Electron and Thermo Instrument.

Employee Stock Purchase Program

Substantially all of the Company's full-time U.S. employees are eligible to
participate in an employee stock purchase program sponsored by Thermo Instrument
and Thermo Electron. Under this program, shares of Thermo Instrument's and
Thermo Electron's common stock can be purchased at the end of a 12-month period
at 95% of the fair market value at the beginning of the period, and the shares
purchased are subject to a six-month resale restriction. Prior to November 1,
1995, the applicable shares of common stock could be purchased at 85% of the
fair market value at the beginning of the period, and the shares purchased were
subject to a one-year resale restriction. Shares are purchased through payroll
deductions of up to 10% of each participating employee's gross wages.

401(k) Savings Plan

Substantially all of the Company's full-time U.S. employees are eligible to
participate in Thermo Electron's 401(k) savings plan. Contributions to the
401(k) savings plan are made by both the employee and the Company. Company
contributions are based upon the level of employee contributions. The Company
contributed and charged to expense $175,000, $178,000, and $176,000 in fiscal
1994, 1995 and 1996, respectively.

Defined Benefit Pension Plans

The Company's German subsidiary has a defined benefit pension plan covering
substantially all of its full-time employees. Benefits are based on a percentage
of eligible earnings for each year of service in excess of ten.

A provision has not been made for U.S. or additional foreign taxes on $6.7
million of undistributed earnings of foreign subsidiaries that could be subject
to taxation if remitted to the U.S. because the Company currently plans to keep
these amounts permanently reinvested overseas. The Company believes that any
additional U.S. tax liability due upon remittance of such earnings would be
immaterial due to available U.S. foreign tax credits.

5. RELATED PARTY TRANSACTIONS

Corporate Services Agreement

The Company and Thermo Electron have a corporate services agreement under
which Thermo Electron's corporate staff provides certain administrative
services, including certain legal advice and services, risk management, certain
employee benefit administration, tax advice and preparation of tax returns,
centralized cash management, and certain financial and other services, for which
the Company pays Thermo Electron annually an amount equal to 1.0% of the
Company's revenues. The Company paid an annual fee equal to 1.25% and 1.20% of
the Company's revenues in 1994 and 1995, respectively. The annual fee is
reviewed and adjusted annually by mutual agreement of the parties. For these
services, the Company was charged $483,000, $552,000 and $520,000 in 1994, 1995
and 1996, respectively. The corporate services agreement is renewed annually but
can be terminated upon 30 days' prior notice by the Company or upon the
Company's withdrawal from the Thermo Electron Corporate Charter (the Thermo
Electron Corporate Charter defines the relationships among Thermo Electron and
its majority-owned subsidiaries). Management believes that the service fee
charged by Thermo Electron is reasonable and that such fees are representative
of the expenses the Company would have incurred on a stand-alone basis. For
additional items such as employee benefit plans, insurance coverage, and other
identifiable costs, Thermo Electron charges the Company based upon costs
attributable to the Company.

Repurchase Agreement

The Company invests excess cash in a repurchase agreement with Thermo
Electron as discussed in Note 1.

Due to parent company and affiliated companies

The Company has borrowed funds from a wholly owned subsidiary of Thermo
Optek Corporation, a majority-owned subsidiary of Thermo Instrument, pursuant to
certain promissory notes. The Company had $1,388,000 and $1,928,000 outstanding
under the promissory notes at year-end 1995 and 1996, respectively. The notes
bear interest at a variable rate. The interest rate for the notes outstanding at
year-end 1995 and 1996 was 4.6% and 3.8%, respectively. The notes were repaid in
February 1997. In addition, the Company had $3,617,000 and $2,611,000 of
noninterest-bearing advances from Thermo Instrument and affiliated companies at
year-end 1995 and 1996, respectively, which are due on demand.

In December 1996, the Company borrowed $2,778,000 pursuant to a
noninterest-bearing advance from a wholly owned subsidiary of Thermo Instrument,
which was repaid on January 15, 1997.

Other Related Party Services

The Company leases office and manufacturing space in Germany to a wholly
owned subsidiary of Thermo Instrument pursuant to an arrangement whereby the
Company charges the Thermo Instrument subsidiary its allocated share of the
occupancy expenses of the Company's German facility, based on space utilized.
Pursuant to this arrangement, the Company recorded $302,000, $367,000 and
$368,000 in 1994, 1995 and 1996, respectively, as a reduction in selling,
general and administrative expenses in the accompanying statement of income.

deutsche marks pursuant to a promissory note, payable in monthly installments of
99,200 German deutsche marks with a final payment in October 2004. The balance
outstanding was $7,297,000 and $5,988,000 at year-end 1995 and 1996,
respectively. The loan is secured by property at the Company's German subsidiary
with a net book value of $9,746,000 at year-end 1996. The note bears interest at
a variable rate, which was 4.7% and 3.75% at year-end 1995 and 1996,
respectively.

The annual repayment requirements of the long-term obligation as of
December 28, 1996, are $765,000 in each year from 1997 through 2001 and

9. SUBSEQUENT EVENT

Acquisition

On December 31, 1996, the Company acquired the assets, subject to certain
liabilities, of the Autometrics division of Svedala Industries Inc.
("Autometrics"), for $1,347,000 in cash. Autometrics is a manufacturer and
marketer of on-line analysis instruments for the minerals processing industry.

The acquisition has been accounted for using the purchase method of
accounting and its results of operations have been included in the accompanying
financial statements from its date of acquisition. The cost of the acquisition
exceeded the estimated fair value of the acquired net assets by $400,000, which
is being amortized over 40 years. Allocation of the purchase price was based on
an estimate of the fair value of the net assets acquired and is subject to
adjustment upon finalization of the purchase price allocation. To date no
information has been gathered that would cause the Company to believe that the
final allocation of the purchase price will be materially different than the
preliminary estimate.

Based on unaudited data, the following table presents selected financial
information for the Company and Autometrics on a pro forma basis, assuming the
Companies had been combined since the beginning of 1996. Pro forma data is not
presented for the three months ended March 29, 1997 since the results of the
Company and Autometrics were combined for substantially the entire period.

split. All share and per share information has been restated to reflect the

Analyzer sits in an open field two stories high and is supported and surrounded
by scaffolding with walkways for access to the analyzer. On the right of the
Coal Analyzer, a covered conveyor belt is shown bringing coal to the top of the
analyzer and a second conveyor belt is shown taking the analyzed coal away from
the bottom of the analyzer.

[CAPTION]

The Company's On-line Coal Analyzer uses neutron interrogation to determine the
sulfur and ash concentration of the coal, and can analyze streams of coal at a
rate of up to four hundred tons per hour. Customers then use this data to blend
and sort coal to improve its quality and to optimize combustion processes.

Photo 4 -- Photo of the Company's Cross Belt Analyzer in a cement plant. The
Company's Cross Belt Analyzer sits on a platform in a corrugated metal
building, which also supports a conveyor belt transporting raw material through
the Cross Belt Analyzer. Scaffolding and walkways surround the analyzer for
access to it.

[CAPTION]

The Company's Cross Belt Analyzer ("CBA") is currently used primarily by the
cement industry to analyze the composition of raw materials. The CBA analyzes
materials at rates in excess of 1,000 tons per hour, and can incorporate
high-speed proprietary software which allows the customer to automatically
control and optimize production processes.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

The Delaware General Corporation Law and the Registrant's Certificate of
Incorporation and By-Laws limit the monetary liability of directors to the
Registrant and to its stockholders and provide for indemnification of the
Registrant's officers and directors for liabilities and expenses that they may
incur in such capacities. In general, officers and directors are indemnified
with respect to actions taken in good faith in a manner reasonably believed to
be in, or not opposed to, the best interests of the Registrant, and with respect
to any criminal action or proceeding, actions that the indemnitee had no
reasonable cause to believe were unlawful. The Registrant also has
indemnification agreements with its directors and officers that provide for the
maximum indemnification allowed by law. Reference is made to the Registrant's
Certificate of Incorporation, By-Laws and form of Indemnification Agreement for
Officers and Directors incorporated by reference as Exhibits 3.1, 3.2 and 10.12
hereto, respectively.

Thermo Electron has an insurance policy which insures the directors and
officers of Thermo Electron and its subsidiaries, including the Registrant,
against certain liabilities which might be incurred in connection with the
performance of their duties.

Under the Underwriting Agreement, the Underwriters are obligated, under
certain circumstances, to indemnify directors and officers of the Registrant
against certain liabilities, including liabilities under the Securities Act of
1933, as amended (the "Securities Act"). Reference is made to the form of
Underwriting Agreement filed as Exhibit 1 hereto.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

On November 26, 1996, the Registrant issued 5,000,000 shares of Common
Stock (adjusted to reflect a one-for-two reverse stock split effected in May
1997) to Thermo Instrument System Inc. in exchange for the assets, liabilities
and business of its Gamma-Metrics subsidiary and Radiometrie division at the
time of the incorporation of the Registrant. Exemption from registration of this
transaction is claimed under Section 4(2) of the Securities Act.

On December 16, 1996 the Registrant sold an aggregate of 833,333 shares of
Common Stock to accredited investors for an aggregate purchase price of
$12,500,000, pursuant to Regulation D of the Commission promulgated under the
Securities Act. On December 27, 1996, the Registrant sold an

II-1

aggregate of 134,500 shares of Common Stock to accredited investors for an
aggregate purchase price of $2,017,500 pursuant to Regulation D of the
Commission promulgated under the Securities Act.

ITEM 16. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES

(a) EXHIBITS

See the Exhibit Index included immediately preceding the exhibits to this
Registration Statement.

(b) FINANCIAL STATEMENT SCHEDULES

Financial Statement Schedules as of December 28, 1996 and the Report of
Independent Accountants on such schedules are included in this Registration
Statement. All other schedules are omitted because they are not applicable or
are not required under Regulation S-X.

ITEM 17. UNDERTAKINGS

(a) The undersigned Registrant hereby undertakes to provide to the
Underwriters at the closing specified in the Underwriting Agreement certificates
in such denominations and registered in such names as required by the
Underwriters to permit prompt delivery to each purchaser.

(b) The undersigned Registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities
Act, the information omitted from the form of prospectus filed as part of
this Registration Statement in reliance upon Rule 430A and contained in the
form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
(4) or 497(h) under the Securities Act shall be deemed to be part of this
Registration Statement as of the time it was declared effective

(2) For the purpose of determining any liability under the Securities
Act, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bon fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions contained in the Certificate of
Incorporation and By-Laws of the Registrant and the laws of the State of
Delaware, or otherwise, the Registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
