ITEM 1.  BUSINESS

                 (A) GENERAL DEVELOPMENT OF BUSINESS

   Oak Industries Inc. ("Oak" or the "Registrant") was incorporated under 
the laws of the State of Delaware in 1960.  The predecessor of Oak was 
incorporated in 1932 under the laws of the State of Illinois.  Oak adopted 
its present corporate name in 1972.  Oak's executive offices are located at 
1000 Winter Street, Waltham, Massachusetts 02451, and its telephone number 
is (781) 890-0400.  References herein to the "Company" refer to Oak and its 
consolidated subsidiaries.

   The Company has four operating segments:  the manufacture of coaxial 
connector products used primarily in the CATV industry (the "Cable 
Broadband Products Segment");  the manufacture of quartz-based crystals and 
oscillators for wireless base stations and telecommunications applications 
(the "Frequency Control Products Segment"); the manufacture of fiber-optic 
components used primarily in wired telephony networks (the "Fiber-Optic 
Products Segment"); and the  manufacture of components for gas ranges and 
switches and encoders used in a variety of applications (the "Controls 
Products Segment").

   On October 30, 1998 the Company purchased 100% of the outstanding 
capital stock of Tele Quarz GmbH ("Tele Quarz").  Tele Quarz, located in 
Neckarbischofsheim, Germany, is a manufacturer of frequency control 
products.  The total purchase price for the capital stock and certain real 
estate, including debt assumed and transaction costs, was approximately 
$63.5 million.  (See Note 3 "Acquisitions" of the Notes to Consolidated 
Financial Statements). 

   On October 30, 1998, the Company purchased the remaining 3.75% of 
Gilbert Engineering Co., Inc. ("Gilbert") owned by current and former 
members of Gilbert management for a purchase price of approximately $11.4 
million.  The Company has owned 100% of Gilbert since October 30, 1998.

      (B) FINANCIAL INFORMATION ABOUT REPORTABLE SEGMENTS

   For information regarding sales, income, assets and capital expenditures 
of the Company's reportable segments, see Note 10 of the Notes to 
Consolidated Financial Statements, which is incorporated herein by

            (C) NARRATIVE DESCRIPTION OF BUSINESS

Overview

   The Company is a leading manufacturer of highly-engineered components 
that it designs and sells to manufacturers and service providers in 
communications and other selected industries.  The Company's communications 
products consist primarily of connectors for the CATV industry ("Cable 
Broadband Products"), frequency control devices used in wireless base 
stations and telecommunications applications ("Frequency Control 
Products"), and dense wavelength division multiplexing ("DWDM") fiber-optic 
components for the wired telephony infrastructure ("Fiber-Optic Products").  
The Company's controls products include components for gas ranges, and 
switches and encoders, which are used in a wide range of applications 
(collectively, "Controls Products").  

Business Strategy

   The Company's objective is to establish and maintain a leading position 
in markets with strong underlying growth characteristics.  The Company 
attempts to achieve this position by providing a broad line of products 
that meets the quality and price/performance targets of its customers.  The 
key elements of the Company's strategy include the following:

   Maintain Technology Leadership.  The Company believes that its strong 
competitive position is attributable in large part to its engineering 
capabilities.  The Company believes that its investment in engineering 
resources enables it to maintain technological leadership and will enable 
it to increase its customer base by developing products that meet its 
customers' specific technical requirements.

   Develop New Products and Increase Market Share.  The Company plans to 
continue to increase sales by developing additional products that can be 
sold to existing customers and by expanding its customer base.  For 
example, the Fiber-Optic Products Segment has introduced higher-power 
versions of its pump lasers designed for new DWDM applications.  In 
addition, the Frequency Control Products Segment has introduced a voltage 
controlled oscillator product line, expanding its customer base to include 
manufacturers of switching and transmission equipment in addition to its 
traditional customer base of manufacturers of wireless base stations and 
military and satellite equipment.  The Cable Broadband Products Segment 
recently began supplying new premium drop connectors used on smaller-
diameter coaxial cables at a subscriber's house.  The Controls Products 
Segment recently introduced a new sealed system for gas ranges and a 
modulating thermostat to broaden its product offerings.  

   Expand International Presence.  The Company intends to continue to 
increase its international presence.  In October of 1998, the Company 
purchased Tele Quarz, a leading manufacturer of frequency control devices 
located in Germany.  The Company currently has foreign manufacturing 
facilities in Canada, China, Denmark, France, Germany and Mexico, and also 
participates in a manufacturing joint venture in China.  Sales made by the 
Company to customers located outside the United States accounted for 
approximately 31% of the Company's sales for the year ended December 31, 
1998.

   Reduce Manufacturing Costs.  The Company aggressively pursues a strategy 
of improving its manufacturing efficiencies to reduce the cost and increase 
the quality of its products.  The Company engineers its products for volume 
manufacturing and continues to evaluate and redesign its products in order 
to reduce manufacturing costs.  The Company has also invested significantly 
in the automation of its manufacturing facilities.  The Company intends to 
continue to invest in enhancing its manufacturing capabilities with the 
objective of meeting the quality and price/performance targets of customers 
while maintaining strong operating margins.  For example, in 1998 the 
Company opened a facility in Tennessee closer to a number of its key 
Controls Products Segment customers.  As a result, it has been able to 
provide completed subassemblies to meet these customers' daily production 
schedules in an efficient and cost-effective manner.

   Grow Through Strategic Acquisitions.  The Company's sales have increased 
in part through acquisitions, including Gilbert in 1992, Cabel-Con A/S in 
1994, Lasertron, Inc. in 1995, Piezo Crystal Company ("Piezo") in 1997 and 
Tele Quarz in 1998.  The Company also has divested non-strategic businesses 
in order to make more effective use of available capital.  The Company 
plans to continue pursuing strategic acquisitions that complement its 
existing businesses.  The Company believes that the benefits of such 
acquisitions include expanding the product lines of the Company and 
increasing its customer base.

Cable Broadband Products Segment

   The Cable Broadband Products Segment is a leading worldwide manufacturer 
of coaxial connectors for the CATV industry.  The Company manufactures 
connectors for the trunk and feeder portion of the broadband distribution 
network.  These connectors are used whenever a coaxial cable is cut or 
spliced, such as at connection points for amplifiers, power supplies, and 
other active and passive devices.  The Company also manufactures drop 
connectors that connect the subscriber's television to the cable network.  
Many of the Company's customers have different specifications for their 
connectors.  The Company offers over 1,700 different types of connectors.  
Connectors are complex components; for example, trunk and feeder connectors 
may have as many as 20 parts, many of which are individually machined prior 
to assembly of the connector. 

   A cable system consists of three principal segments.  The first is the 
headend, where the cable system operator receives television signals via 
satellite, terrestrial, microwave and other sources.  The headend 
organizes, processes and retransmits those signals through the second 
segment, the distribution network, to the subscriber.  The distribution 
network typically consists of coaxial and fiber-optic cables and associated 
equipment that takes the signals from the headend and then transmits them 
throughout the cable system.  The third segment is the subscriber drop, 
which extends from the distribution network to the subscriber's home, and 
connects either directly to the subscriber's television set or to a 
converter box.  Connectors are used throughout the system where coaxial 
cable connects to electronic equipment such as amplifiers and at various 
distribution and termination points.

   Cable operators continue to upgrade the technological capabilities of 
their systems in order to provide subscribers with improved signal quality 
and increased channel capacity that allows a broader range of digital 
services, Internet access through cable modems, and telephony.  Cable 
networks are also being upgraded in response to competitive multichannel 
services such as direct broadcast satellite and wireless cable.  Industry 
data indicate that a large portion of domestic cable systems have not yet 
been upgraded to the quality required by CATV operators for the delivery of 
digital services and to provide for a return path for two-way services such 
as Internet access and telephony.  The Company also anticipates continued 
growth in the cable industry internationally, where cable penetration rates 
typically are still low, although international sales were affected during 
the last year by financial constraints in certain markets.  The Company 
believes that opportunities for increased revenues for its Cable Broadband 
Products will arise in connection with the anticipated upgrading of 
domestic cable systems and expansion of the cable industry internationally, 
and from recently developed new products. 

   The Cable Broadband Products Segment regularly introduces new products 
to expand its presence in existing markets.  It has expanded its line of 
drop connectors and has redesigned its two-piece trunk and feeder connector 
product line.  In addition to CATV connectors, the Company manufactures a 
line of microwave connectors that are used primarily in high reliability 
applications in satellites and telecommunications systems, and also 
produces a line of connectors used to connect tower-based antennas to 
wireless base stations.

   The Cable Broadband Products Segment sells directly to major multiple 
system operators and leading distributors of CATV components.  The Cable 
Broadband Products Segment manufactures products in Glendale and Phoenix, 
Arizona; Vordingborg, Denmark; and Amboise, France.

   The market for Cable Broadband Products is highly competitive with 
respect to price, quality and delivery; however, the Company believes it 
competes favorably with respect to each of these factors.  Cable Broadband 
Products are engineered to meet stringent customer reliability 
requirements.  Certain parties are attempting to develop technologies that 
could compete with those currently employed by the customers for Cable 
Broadband Products.  If successful, these developments could have a 
negative impact on the business of the Cable Broadband Products Segment.

   The primary raw materials used in the manufacture of Cable Broadband 
Products are aluminum and brass.  The Company currently receives its 
aluminum requirements from two different manufacturing facilities of a 
single supplier.  Although the Company believes several alternative sources 
of supply of aluminum are available, a sudden disruption of its supply from 
this vendor could have a temporary adverse effect on the manufacture and 
sale of Cable Broadband Products.  The Company is not dependent on any 
single supplier for its other significant raw material requirements for 
Cable Broadband Products.  The Company believes it will be able to obtain 
the raw materials necessary to manufacture its Cable Broadband Products.  

   The Cable Broadband Products Segment has several major customers.  The 
loss of, or reduced demand for products from, any major customer of this 
segment could have a material adverse effect on the segment.

   The Company owns a number of patents with respect to its Cable Broadband 
Products but the Company does not consider any one patent or group of 
patents material to the conduct of the Cable Broadband Products Segment's 
business.

Frequency Control Products Segment

   The Frequency Control Products Segment is a leading supplier of quartz-
based crystals and oscillators for use in wireless, wired telephony, 
military, satellite, and other communications applications as well as for 
automotive applications.  Crystals and oscillators are highly-engineered 
components that provide critical timing or frequency references for 
wireless communications networks, wired telephony systems, satellite 
communications and other electronic applications requiring a high degree of 
signal precision.  The Frequency Control Products Segment also manufactures 
glass-to-metal hermetically sealed packages used primarily in the frequency 
control industry. 

   The Frequency Control Products Segment includes divisions that 
manufacture oscillators, quartz crystals that are the key components in 
oscillators, and bases for crystals and oscillators.

   There are four primary classes of crystal oscillators:  (i) 
uncompensated crystal oscillators or "XOs", (ii) temperature compensated 
crystal oscillators or "TCXOs", (iii) voltage controlled crystal 
oscillators ("VCXOs"), and (iv) oven controlled crystal oscillators 
("OCXOs").  The type used depends on the performance characteristics 
required and the environment to which the oscillator will be exposed.  The 
Company has designed products that can be used with all major analog and 
digital technologies used by cellular telephone and Personal Communications 
Systems, or "PCS" service providers, including Code Division Multiple 
Access, or "CDMA," Time Division Multiple Access, or "TDMA," and Global 
Systems for Mobile Communications, or "GSM."

   The Company's development efforts are focused on addressing market 
demands for Frequency Control Products with higher stability, smaller size 
and lower power consumption.  It has also invested in highly automated 
production and test systems to increase capacity.  Growth in the Frequency 
Controls Products Segment's sales has been driven primarily by the growth 
of wireless infrastructure spending.  The Company expects continued growth 
in wireless infrastructure spending in the United States and 
internationally to support the substantial increase in the number of 
wireless subscribers.  In emerging markets abroad, wireless is viewed as a 
viable substitute for wired telephony.  

   The Company sells its Frequency Control Products using a direct sales 
force and manufacturers' representatives.  The Company supplies oscillators 
and crystals to leading manufacturers of wireless base stations and 
telecommunications equipment, as well as manufacturers of test, 
instrumentation and other equipment and automotive systems.  The Company 
also sells to a large number of smaller communications companies.  The 
market for frequency control devices is highly competitive in terms of 
price, quality and delivery.  The Company believes it competes favorably 
with respect to each of these factors.

   The Frequency Control Products Segment's manufacturing facilities are 
located in Mt. Holly Springs, Carlisle, and Mercersburg, Pennsylvania; 
Kansas City, Kansas; Whitby, Ontario, Canada; Shanghai, China; and 
Neckarbischofsheim, Germany.

   There are many domestic and foreign suppliers of frequency control 
devices.  In order to compete effectively in this market, the Company 
places a strong emphasis on high quality.  A large percentage of the 
Company's Frequency Control Products are manufactured to exacting customer 
specifications, and the Company relies to a great extent on its engineering 
staff to design and provide post-production support to meet customer needs.

   The Company believes the raw materials required for the production of 
its Frequency Control Products are readily available.  There are multiple 
suppliers of such raw materials, and the Company utilizes many suppliers.

   The Frequency Control Products Segment has several major customers.  The 
loss of, or reduced demand for products from, any major customer of this 
segment could have a material adverse effect on the segment.

   The Company owns a number of patents with respect to its Frequency 
Control Products but the Company does not consider any one patent or group 
of patents material to the conduct of the Frequency Control Products 
Segment's business.

Fiber-Optic Products Segment

   The Fiber-Optic Products Segment designs, manufactures and sells active 
DWDM fiber-optic components used in long distance and metropolitan wired 
telephony networks and semiconductor lasers for telecommunications 
applications.

   The Company's Fiber-Optic Products include pump lasers that are critical 
components of optical amplifiers and increase the power of light signals.  
Optical amplifiers are placed at intervals in the network or at the source 
of the light signal.  The Company's pump lasers are deployed in the major 
domestic long distance networks and in rings connecting headends in the 
CATV market.  The Company also designs and manufactures transmission 
components that are used to generate or detect optical signals carried on 
fiber-optic links.  The Fiber-Optic Products Segment has developed a line 
of advanced transmission products, known as distributed feedback lasers 
("DFBs"), for applications in long distance and other networks.  These 
advanced transmission products generate fiber-optic signals at the rate of 
2.5 gigabits per second.  The Fiber-Optic Products Segment also 
manufactures standard transmission products for the local loop, such as 
laser sources and detectors, which operate at lower speeds. 

   Telecommunication service providers are experiencing a significant 
increase in data traffic.  Data transmissions now account for a substantial 
portion of traffic on many networks and the volume of data being 
transmitted is growing very rapidly.  The increase in data traffic results 
primarily from the growing number of Internet users, home offices, and 
additional telephone lines, and the increased use of electronic mail and 
wireless calls that terminate on the wired network.  The Company believes 
that service providers will continue to upgrade existing networks to 
increase capacity.

   The Company owns a 50% interest in Wuhan Telecommunication Devices Co. 
("WTD") located in Wuhan, China.  WTD is a manufacturer of fiber-optic, 
semiconductor laser components for the communications industry.  A research 
division of the Chinese Ministry of Information Industry, Wuhan Optical 
Communication Technology Company, owns the other 50% interest of WTD.

   The Company's Fiber-Optic Products are sold both directly and through 
distributors to domestic and export customers, which are primarily 
manufacturers of fiber-optic communications and CATV communications 
equipment.

   The Fiber-Optic Products Segment's manufacturing facilities are located 
in Bedford, MA and Wuhan, China.

   Although the market for the Company's Fiber-Optic Products is highly 
competitive with respect to quality, price and delivery, the Company 
believes that the Fiber-Optic Products Segment competes favorably with 
respect to each of these factors.  The Company believes that the Fiber-
Optic Products Segment is very competitive in the area of high-power pump 
lasers, for which there is currently high demand.  While several of the 
Company's customers have captive operations that make products for their 
own use and for sale to others that compete with those of the Company, 
these customers have historically relied on the Company to supply a portion 
of their product needs.

   The Company's Fiber-Optic Products incorporate semiconductor diode laser 
and detector "chips" that are coupled to an optical fiber and supplied as 
compact fiber-optic modules.  One high volume chip is purchased from a sole 
supplier, although the Fiber-Optic Product Segment now also produces this 
chip internally.  Internal production of this chip currently requires 
purchasing wafer raw material from a limited number of external suppliers, 
although the Fiber-Optic Product Segment is developing the capability to 
produce this raw material internally in addition to sourcing it externally.  
An inability to obtain these chips or wafers externally in sufficient 
quantities to meet projected needs could have a material adverse effect on 
the Fiber-Optic Products Segment's business.

   The Fiber-Optic Products Segment sells products to a concentrated group 
of customers.  The loss of, or reduced demand for products from, any major 
customer of this segment could have a material adverse effect on the 
segment.

   The Fiber-Optic Products Segment licenses a number of patents from third 
parties and the Company considers several licenses to be material to the 
conduct of its business.

Controls Products Segment

   The Controls Products Segment is a leading supplier of components to the 
original equipment manufacturers of gas range appliances and also supplies 
components for outdoor gas grills.  The Controls Products Segment also 
includes the manufacture of optical, rotary and appliance switches and 
encoders for applications in the test and measurement, communications, 
medical, military and other markets.

   The Controls Products Segment offers a broad line of components and 
replacement parts for gas ranges for sale to original equipment 
manufacturers.  These components control the flow of gas to, and the 
ignition and temperature of, burners and ovens.  The Controls Products 
Segment supplies components to the major domestic gas range manufacturers, 
as well as gas range manufacturers in Canada, Mexico, and Latin America.  
The Controls Products Segment also supplies service parts for gas ranges 
and sells gas grills for outdoor cooking. 

   The Controls Product Segment also manufactures optical, rotary and 
appliance switches and encoders for applications in the appliance, test and 
measurement, communications, medical, military and other markets.  These 
products include low-power open frame switches, enclosed and encoded rotary 
switches, as well as solenoids, lighted push-button switches and appliance 
switches.  To keep pace with the transition of its customer base from 
traditional analog switch technology to digital controls, the Controls 
Product Segment has also developed sensors and controls that eliminate many 
of the mechanical aspects of rotary switches.  These products translate an 
input, such as motion, into electronic output.

   The Company has made significant investments in engineering resources 
and computer-aided design capabilities to shorten its new product 
development cycle.  New products include ignition systems, a sealed supply 
system, and subassemblies that range manufacturers incorporate directly 
into their ranges in their production lines.  The Company plans to continue 
to develop new products for its existing customers. 

   The Company recently opened a satellite manufacturing facility in 
Tennessee.  This facility is located near several major customers of 
Controls Products and allows the Company to provide just-in-time delivery 
of components and subassemblies to these customers.

   The Company sells its Controls Products primarily through a direct sales 
force and through manufacturers' representatives.  The Controls Products 
Segment has highly automated manufacturing facilities for gas range 
components in Princeton, Illinois, Ooltewah, Tennessee, and Juarez, Mexico.  
The Controls Products Segment's principal manufacturing operations for 
switch and encoder components take place in Juarez, Mexico.

   The Controls Products market is highly competitive in terms of price, 
quality and delivery.  The Company believes it competes favorably with 
respect to each of these factors.  The Controls Products Segment is a 
leading supplier to the domestic market for gas range components.  Its 
domestic gas range components must conform to Underwriters' Laboratories 
and American Gas Association specifications.  All such approvals for 
existing products have been obtained and the Controls Products Segment's 
quality assurance team maintains compliance with these specifications.

   The Controls Products Segment is not dependent upon any single supplier 
for raw materials.  

   The Controls Products Segment has several major customers.  The loss of, 
or reduced demand for products from, any major customer of this segment 
could have a material adverse effect on the segment.

   The Company owns a number of patents relating to its Controls Products 
but the Company does not consider any one patent or group of patents 
material to the conduct of the Controls Products Segment's business.

Employees

   At December 31, 1998, the Company had 3,875 employees, 2,046 of whom 
worked at locations in the United States and 1,829 at locations outside the 
United States.  Of these employees, 187 are subject to collective 
bargaining agreements.  The Company believes that its relationships with 
its employees are good.

Description of certain unusual transactions

1998

   Results include unusual charges of $2.5 million related to the 
reorganization of certain operations within the Frequency Control Products 
Segment and $0.5 million related to the planned discontinuation of certain 
product lines within the Controls Products Segment.  These unusual charges 
included severance of $0.5 million and other reorganization charges of $0.2 
million reported as selling, general and administrative expenses, and 
amounts charged to cost of goods sold for inventory write-downs of $1.4 
million, and plant and equipment write-downs of $0.9 million.

   Results also include a $1.0 million charge to cost of goods sold related 
to the purchase accounting for inventory at Tele Quarz.

1997

   Results include a $0.6 million charge to cost of goods sold related to 
the purchase accounting for inventory at Piezo.

1996

   Unusual transactions include a gain of $21.5 million from the sale of 
equity investments, reorganization and severance charges of $3.8 million, a 
$4.2 million charge associated with the write-down of certain assets and a 
reserve for potential legal and environmental matters, a $0.9 million 
charge to cost of goods sold related to purchase accounting for inventory, 
an extraordinary charge of $0.9 million net of tax related to the early 
extinguishment of debt, and a gain of $9.4 million net of tax on the sale 
of a subsidiary.

   In early 1997, the Company discovered that the controller of one of its 
divisions capitalized certain costs that should have been expensed during 
1995 and 1996 in the periods incurred.  Because the 1995 errors were not 
material to the 1995 results ($1.1 million before tax, $0.7 million after 
tax), the 1995 financial statements were not restated and the correction of 
improperly capitalized expenses of $1.1 million was reported as an unusual 
item in 1996.

Comparison of Year Ended December 31, 1998 to Year Ended December 31, 1997

   Net Sales.  The Company's net sales for 1998 were $347.9 million, an 
increase of 11% over 1997.  The increase in net sales resulted mainly from 
growth in sales in the Cable Broadband Products Segment and Frequency 
Control Products Segment.  Sales by the Frequency Control Products Segment 
for 1998 increased 33% over 1997 levels as the result of strong demand from 
customers in the wireless communications infrastructure industry and as the 
result of the addition of sales by Tele Quarz and Piezo.  The Cable 
Broadband Products Segment's sales for 1998 increased by 16% over 1997 
sales levels as a result of strong demand from domestic CATV customers and 
as a result of the successful introduction of several new products.  These 
increased sales by the Cable Broadband Products Segment to domestic 
customers offset a decline in sales to international customers during 1998.  
Sales by the Fiber-Optic Products Segment for 1998 declined slightly from 
sales in 1997.  The Fiber-Optic Products Segment's sales results for 1997 
included significant sales to one European customer for a program that was 
not active in 1998.  There was a significant increase in sales to customers 
other than this one European customer during 1998.  The Controls Products 
Segment's sales increased slightly from 1997 to 1998.  Within this segment, 
sales of gas range components increased as the result of market share gains 
and the introduction of several new products and switch and encoder sales 
declined as the result of a reduction in sales of a product used in a 
United States government postal sorting system.  

   Gross Profit.  The Company's gross profit margin, excluding unusual 
transactions, decreased to 37.0% in 1998 compared to 37.2% in 1997.  Gross 
profit margin increased slightly in 1998 compared to 1997 in the  Cable 
Broadband Products and Controls Products Segments, while gross profit 
margins decreased somewhat in 1998 compared to 1997 in the Frequency 
Control Products and Fiber-Optic Products Segments.  In general, prices of 
the Company's products declined during the year, while material costs 
remained relatively stable, wages increased moderately, and productivity 
improved.

   Selling, General and Administrative Expenses.  Selling, general and 
administrative expenses, before unusual transactions, increased $4.4 
million, or 6%, in 1998 over those expenses in the prior year.  The 
increase was primarily the result of increased expenses in the Frequency 
Control Products Segment due to the full-year impact of the Piezo 
acquisition and the acquisition of Tele Quarz during the fourth quarter of 
1998.  Research and development and selling expenses increased in 1998 
compared to the level of those expenses in 1997.  Amortization expense 
relating to intangible assets increased to $6.4 million in 1998, versus 
$5.8 million in 1997.  This increase was mainly the result of increased 
goodwill amortization related to the Piezo and Tele Quarz acquisitions.  
Royalty income (reported as an offset against selling, general and 
administrative expenses) was $0.6 million during 1998.  The Company 
reported royalty income of $1.0 million during 1997.

   Interest Expense.  Interest expense decreased from $11.0 million in 1997 
to $10.1 million in 1998.  The decrease resulted primarily because the 
interest rate on the 4 7/8% Convertible Subordinated Notes (the "Notes") 
that were issued by Oak in February 1998 is significantly lower than the 
interest rate on the Company's revolving credit facility balances. 

   Interest Income.  Interest income increased from $0.4 million in 1997 to 
$1.0 million in 1998 primarily as a result of a $0.4 million gain on the 
sale of securities.

   Equity in Net Income of Affiliated Companies.  The Company reported 
equity in net income of affiliated companies of $0.03 million in 1997 and 
$2.0 million during 1998.  The increase is primarily the result of 
increased income at WTD due to increased sales.  The Company also reported 
a gain of $0.3 million as the result of resolving outstanding issues with 
its WTD joint-venture partner that had been reserved for during 1996.  
During 1998, the Company also recorded a gain of $0.8 million from the sale 
to its partner of the Company's 50% interest in a joint venture that 
manufactured quartz crystal blanks in Venezuela. 

   Income Taxes.  The effective income tax rate excluding unusual 
transactions decreased from 37.8% in 1997 to 37.4% in 1998.  The effective 
tax rate for 1998 included a benefit of $0.3 million resulting from the 
favorable resolution of a state income tax matter.

   Minority Interest in Net Income of Subsidiaries.  Minority interest 
expense decreased to $0.7 million in 1998 from $1.1 million in 1997.  The 
decrease resulted from purchases of additional equity interests in Gilbert 
in October 1997 and October 1998.

   Net Income.  Net income excluding unusual transactions was $29.8 million 
in 1998 compared to $22.1 million in 1997.  The increase was the net result 
of the factors described above.

Comparison of Year Ended December 31, 1997 to Year Ended December 31, 1996

   Net Sales.  The Company's net sales for 1997 were $314.4 million, an 
increase of 4% over sales in 1996.  During 1997, sales by the Fiber-Optic 
and Frequency Control Products Segments grew 37% and 28%, respectively, and 
more than offset a decline in sales by the Cable Broadband Products 
Segment.  Demand for Fiber-Optic Products and Frequency Control Products 
was driven by increased infrastructure investments for long distance fiber-
optic networks and for cellular and personal communications systems.  Sales 
by the  Frequency Control Products Segment in 1997 include sales by Piezo, 
which was acquired at the end of the third quarter of 1997.  In October 
1996, the Company's then-largest customer of Cable Broadband Products 
announced a moratorium on purchases.  This CATV customer purchased 
significantly less from the Company in 1997 than it did in 1996.  Sales 
volume by the Cable Broadband Products Segment declined from 1996 to 1997 
as a result of lower sales to this customer, as well as lower sales to 
customers in certain international markets.  Sales by the Cable Broadband 
Products Segment to other CATV customers and sales to microwave products 
customers increased significantly from 1996 to 1997.  The Controls Products 
Segment's sales increased 5% in 1997, principally as the result of growth 
of sales of gas range components.

   Gross Profit.  The Company's gross profit margin excluding unusual 
transactions decreased to 37.2% in 1997 from 39.1% in 1996 primarily as a 
result of the adverse impact of lower production volumes in the Cable 
Broadband Products Segment and increased sales of lower margin Controls 
Products.  These gross margin reductions were partially offset by 
significant margin improvements in the Fiber-Optic Products and Frequency 
Control Products Segments.  In general, prices of the Company's products 
declined during the year, while material costs remained relatively stable, 
wages increased moderately, and productivity improved.

   Selling, General and Administrative Expenses.  Selling, general and 
administrative expenses excluding unusual transactions increased $6.2 
million, or 9.8%, in 1997 over those expenses in the prior year, including 
an increase in research and development and sales and marketing expenses 
over 1996 levels.  Amortization expense relating to intangible assets 
increased in 1997 to $5.8 million, versus $3.6 million in 1996.  This 
increase was the result primarily of increased amortization expense related 
to the November 1996 and October 1997 purchases of additional equity 
interests in Gilbert.  Royalty income (reported as an offset against 
selling, general and administrative expenses) was $1.0 million during 1997, 
and included $0.6 million for royalties related to 1996 that had previously 
been disputed by the licensee of certain technology.  The Company reported 
no royalty income for 1996.

   Interest Expense.  Interest expense increased from $5.8 million in 1996 
to $11.0 million in 1997.  The increase reflected the Company's additional 
borrowings to finance the purchase of additional equity interests in 
Gilbert, the repurchase of shares of the Company's common stock under the 
Company's stock repurchase program, and the acquisition of Piezo.

   Interest Income.  Interest income decreased from $0.5 million in 1996 to 
$0.4 million in 1997 as a result of lower average cash balances.

   Equity in Net Income (Loss) of Affiliated Companies.  The Company 
reported equity in net income (loss) of affiliated companies excluding 
unusual transactions of a loss of $0.01 million in 1996 and income of $0.03 
million during 1997.

   Income Taxes.  The effective income tax rate excluding unusual 
transactions increased from 36.4% in 1996 to 37.8% in 1997 primarily 
because non-tax deductible amortization expense increased as a result of 
the acquisition of additional equity interests in Gilbert in November 1996 
and October 1997.

   Minority Interest in Net Income of Subsidiaries.  Minority interest 
expense decreased to $1.1 million in 1997 from $7.3 million in 1996.  The 
decrease resulted primarily from purchases of additional equity interests 
in Gilbert in November 1996 and October 1997.

   Net Income.  Net income excluding unusual transactions was $22.1 million 
in 1997 compared to $24.8 million in 1996.  The decrease was the net result 
of the factors described above.

LIQUIDITY AND CAPITAL RESOURCES

   Cash flow from operations was $39.2 million for 1998, representing a 
decrease of $8.4 million from cash flow generated during 1997.  During 
1998, inventory and accounts receivable balances increased by $26.0 million 
and $12.9 million, respectively, compared to balances in 1997 in order to 
support increased sales volume and as a result of the acquisition of Tele 
Quarz.  Capital expenditures during 1998 increased to $16.8 million versus 
$14.7 million during 1997.  Capital expenditures during 1998 included 
investments to increase capacity, introduce new products and improve 
information systems.

   The Company has in place a $300 million unsecured revolving credit 
facility (the "Facility").  Borrowings under the Facility bear interest, at 
the option of the Company, either (i) at the prime rate (or, if higher, at 
0.5% above the federal funds rate) or (ii) at a spread ranging from 0.5% to 
1.25% over the reserve-adjusted 1, 2, 3 or 6 month LIBOR.  Certain of the 
Company's subsidiaries have guaranteed the obligations under the Facility.  
The Facility requires the Company to meet certain periodic financial tests 
and prohibits the Company from paying dividends to its stockholders.  
Borrowing capacity under the Facility will be reduced by $50.0 million on 
each of November 1, 1999 and November 1, 2000.  The Facility expires on 
December 31, 2001.  As of December 31, 1998, the Company had outstanding 
loans of $109 million under the Facility.

   On February 25, 1998, the Company issued the Notes.  The Notes are 
convertible into common stock of the Company at a conversion price of 
$38.66 per share.  Interest on the Notes is payable semi-annually in 
arrears on each March 1 and September 1, and the first interest payment was 
made on September 1, 1998.  The net proceeds from the sale of the Notes 
were used to reduce borrowings under the Facility.

   In December 1996, the Company was authorized to expend up to $50.0 
million to repurchase shares of its stock on the open market.  In October 
1998, this program was amended to allow stock repurchases not to exceed 
$75.0 million in the aggregate.  As of December 31, 1998, the Company had 
spent $35.1 million to repurchase 1,602,200 shares of its common stock.  
The Company intends to finance future repurchases of its stock, if any, 
with cash generated by operations and borrowings under the Facility.

   In April 1998, the Company paid $1.0 million to the former shareholders 
of Piezo under the earnout provisions of the 1997 acquisition agreement for 
Piezo.

   On October 30, 1998 the Company purchased 100% of the outstanding 
capital stock of Tele Quarz.  Tele Quarz, located in Neckarbischofsheim, 
Germany, is a manufacturer of frequency control products.  The total 
purchase price for the capital stock and certain real estate, including 
debt assumed and transaction costs, was approximately $63.5 million.  (See 
Note 3 of the Notes to Consolidated Financial Statements).  

   On October 30, 1998, the Company purchased the remaining 3.75% of 
Gilbert owned by current and former members of Gilbert management for a 
purchase price of approximately $11.4 million.  The Company has owned 100% 
of Gilbert since October 30, 1998.

   The Company believes that funds generated by operations and from its 
existing cash balances and the Facility will be sufficient to fund the 
Company's ongoing operations for the foreseeable future.  

IMPACT OF THE EURO CURRENCY

   On January 1, 1999, the members of the European Union established fixed 
conversion rates between their existing currencies ("legacy currencies") 
and one common currency, the "Euro".  As a result, the Euro now trades on 
currency exchanges and may be used for business transactions utilizing 
electronic fund transfer.  Conversion to the Euro has the effect of 
eliminating exchange rate risk between member countries, as exchange rates 
are now permanent.  Beginning in January 2002, new Euro-denominated 
currency will be issued, and legacy currency will be removed from 
circulation during the first six months of that year.  Oak's subsidiaries 
that are affected by the Euro conversion have modified business processes 
to accommodate Euro denominated transactions.  Certain of the Company's 
operations expect to implement additional changes to improve the processing 
of Euro denominated transactions.  The anticipated future increase in Euro 
denominated transactions is not expected to have a material impact on the 
Company's business or results of operations, and the Company believes that 
its currency risk in participating countries may be reduced as the legacy 
currencies are converted to the Euro.

YEAR 2000 COMPLIANCE

Background

   "Year 2000" issues may arise because many existing computer programs use 
only the last two of the four digits that identify a year.  Therefore, 
certain computer programs may not properly recognize a year that begins 
with "20" and these programs may not function correctly once dates 
beginning with "20" start being used. 

   The Company is aware of the Year 2000 issue and its potential associated 
business and financial risks.  The Company completed an initial internal 
assessment of the Year 2000 impact on each of its operating facilities 
during 1997.  As a result of this internal assessment, the Company 
initiated corrective actions at several of its operating facilities.  
During the second quarter of 1998, qualified external consultants performed 
a more detailed assessment of the impact of the Year 2000 on the Company's 
major operating facilities.  This assessment included a review of existing 
corrective action plans and recommendations for additional corrective 
actions.  The cost of this external assessment was approximately $0.1 
million.

   Based on the foregoing assessments, the Company believes that Year 2000 
issues at its operating facilities should not have a material impact on its 
financial or operating performance.  However, pending completion of all 
necessary corrective actions, it is not possible for the Company to 
determine the extent of any difficulty it might experience at its operating 
facilities as a result of Year 2000 issues.  Such problems, or similar 
problems at the Company's customers or suppliers, could temporarily affect 
the Company's performance adversely.

Corrective Action Status

Personal Computers and Local Area Networks:

   Each of the Company's domestic and foreign operating facilities uses 
personal computers and networking hardware and software.  The external 
assessment completed during the second quarter of 1998 identified required 
upgrades and provided information on the steps necessary to upgrade 
hardware and software.  Each operating facility is upgrading its hardware 
and software, where necessary, to ensure personal computers and local area 
networks are Year 2000 compliant.  Many of the required upgrades would have 
been made to keep pace with technological improvements even were they not 
required for Year 2000 compliance, and had been provided for in each 
operating facility's annual budget for capital expenditures and selling, 
general and administrative expenses.  All required upgrades are expected to 
be completed by the third quarter of 1999.  It is estimated that the total 
cost for these upgrades will approximate $0.5 million to $1.0 million.  
This figure includes amounts for capital equipment and amounts to be 
charged to selling, general and administrative expenses. 

Business Systems:

   The term "Business Systems" includes the systems used in materials 
requirements planning, manufacturing and materials control, general ledger 
and other financial systems, order entry and customer activity tracking.

   There is a wide variety of hardware and software used in the Company's 
Business Systems; some of the Company's operating facilities have Business 
Systems that have been developed, in part, "in-house."  The systems have 
been evaluated at each of the operating facilities and categorized as 
follows:

  1)   Already Year 2000 compliant; no action required;
  2)   Software and/or hardware upgrade required; make necessary 
       changes to existing systems; or
  3)   Software and/or hardware upgrade required; replace existing 
       system with upgraded Year 2000 compliant system.

   For existing systems that are to be revised to be brought into 
compliance, Year 2000 program plans are in place and the majority of the 
work has been completed.  All remaining work is expected to be completed by 
the third quarter of 1999.  There is no significant incremental cost to 
these efforts because the majority of the work is being performed by 
internal management information systems personnel.  These expenses are 
reported as selling, general and administrative expenses as incurred.

   At operating facilities where an existing system is being replaced with 
a new system, program plans have been or will be established to ensure the 
new systems are operational by the third quarter of 1999.  These upgrades 
are necessary investments for the operating facilities to keep pace with 
technology and to enhance operational performance, in addition to being 
required to ensure Year 2000 compliance. 

   The Company has focused the required resources on this area and 
anticipates that all systems will be compliant by the third quarter of 
1999.  Approximately $3.0 million in capital investment has been made to 
date for these systems improvements.  The Company has planned an additional 
$1.5 million to $2.5 million in capital expenditures for upgrades still to 
be completed.

Corporate-Wide Systems:

   The Company's corporate-wide electronic mail system and the corporate 
financial reporting system will be upgraded by the end of the second 
quarter of 1999. These systems are being upgraded to improve operational 
performance.  The upgraded systems will be Year 2000 compliant.  The total 
cost for these upgrades is approximately $1.2 million, including 
capitalized amounts and selling, general and administrative expenses.

Other:

   The Company has also identified certain corrective actions necessary to 
ensure other computer-dependent equipment is Year 2000 compliant.  This 
equipment includes telephone systems and computer-controlled manufacturing 
equipment.  The Company believes that only minor efforts are required in 
these areas to ensure Year 2000 compliance.

Funding for Required Corrective Actions

   The Company believes it has budgeted sufficient funds to ensure all 
required corrective actions are completed in time to avoid Year 2000 
problems.  The Company does not believe that costs required to address its 
Year 2000 issues at its operating facilities will have a material financial 
impact.

Year 2000 Compliance of Suppliers and Customers

   The Company is presently surveying selected suppliers, customers and 
service providers that are material to the Company's business to ensure 
they are Year 2000 compliant, and will complete this process by mid-1999.  
Where practicable, the Company will attempt to mitigate its risks with 
respect to the failure of suppliers to be Year 2000 compliant.  In the 
event that certain suppliers indicate that they will not be Year 2000 
compliant, and this non-compliance is expected to result in failure to meet 
the Company's requirements, the Company will seek alternative suppliers.  
However, such failures could temporarily affect the Company's operations.

Products

   The products produced by the Company do not include date references that 
could be affected by the Year 2000 issue, and therefore the Company does 
not believe there is a material risk of warranty claims related to the Year 
2000 issue.

Risks 

   If certain of the Company's systems fail to be brought into Year 2000 
compliance, the most likely worst-case scenario would be a temporary 
disruption of operations during the implementation of alternative manual 
systems.  The Company believes the impact of such a temporary disruption 
would not be material. 

Contingency Plans

   Because of the rapidly changing Year 2000 situations at the Company and 
its suppliers, customers and service providers, the Company has not 
developed formal contingency plans to address the possibility that its 
planned corrective actions may not achieve Year 2000 compliance.  The 
Company will consider the need for such contingency plans as it continues 
to assess the Year 2000 risk and monitors the progress of its corrective 
action plans.  

RECENTLY ENACTED ACCOUNTING PRONOUNCEMENTS

   In June 1998, the FASB issued Statement of Financial Accounting 
Standards No. 133 ("SFAS No. 133"), "Accounting for Derivative Instruments 
and for Hedging Activities."  SFAS No. 133 requires companies to record 
derivatives on the balance sheet as assets or liabilities, measured at fair 
value.  Gains or losses resulting from the changes in the values of those 
derivatives would be accounted for depending on the use of the derivatives 
and whether they qualify for hedge accounting.  The requirements of this 
statement are to be adopted by the Company as of the first quarter of 2000.  
The Company is assessing the impact of SFAS No. 133 on its financial 
position and results of operations.

RISKS AND UNCERTAINTIES

   Statements contained in the Management's Discussion and Analysis of 
Financial Condition and Results of Operations that are not statements of 
historical fact may include forward looking statements within the meaning 
of the Private Securities Litigation Reform Act of 1995, including, without 
limitation, statements as to expectations, beliefs and strategies regarding 
the future.  It is important to note that actual results could differ 
materially from such forward looking statements due to a number of factors, 
including, among other things, the factors set forth below.  The forward 
looking statements should be considered in light of these factors.

   A significant portion of the Company's revenues is attributable to sales 
of components for building, maintaining and expanding the communications 
infrastructure.  These components are used primarily in cable, wireless and 
wired telephony systems in the United States and internationally.  The 
amount of capital spending in these industries is affected by a variety of 
factors, including general economic conditions, availability of financing, 
government regulation, demand for the products and services offered by the 
Company's customers and technological developments.  A decrease in capital 
spending for communications infrastructure could have a material adverse 
effect on the Company's business, financial condition and results of 
operations.

   The communications industry is very competitive and is characterized by 
rapid technological change, new product development, product obsolescence 
and evolving product specifications.  Additionally, price competition in 
this market is intense with significant price erosion over the life cycle 
of a product.  The ability of the Company to compete successfully depends 
on the continued introduction of new products and ongoing manufacturing 
cost reduction.  The Company believes that it will continue to see varying 
degrees of price pressure across all product lines.  These price pressures, 
if not offset by cost reductions, could result in lower average gross 
margins.

   Certain of the Company's business units sell products to a concentrated 
group of customers.  The loss of, or reduced demand for products from, any 
of the Company's major customers could have a material adverse effect on 
the Company's business, financial condition and results of operations.

   The Company's international operations are subject to a variety of 
risks, including changes in policy by foreign governments, social 
conditions such as civil unrest, and economic conditions including high 
levels of inflation, fluctuation in the value of foreign currencies and 
currency exchange rates and trade restrictions or prohibitions.  Such 
factors could adversely affect the Company's international operations and 
have a material adverse effect on the Company's business, financial 
condition and results of operations.  In addition, although the Company's 
direct sales to customers in Asia have historically been a small percentage 
of total sales, the Company sells to customers that do business worldwide 
and cannot predict how the businesses of these customers may be affected by 
economic conditions in Asia or elsewhere.

   The Company has completed an assessment of the impact of the Year 2000 
on computers and software at its operating units.  This assessment included 
a review of the Company's year 2000 readiness by qualified independent 
consultants.  The Company has identified a number of potential problems and 
corrective actions required.  Some of these actions have already been, and 
others remain to be, completed.  The Company believes that Year 2000 issues 
at its facilities should not have a material impact on its financial or 
operating performance.  However, pending completion of all necessary 
corrective actions, it is not possible for the Company to determine the 
extent of any difficulty it might experience at its facilities as a result 
of Year 2000 issues.  Such problems, or similar problems at the Company's 
customers or suppliers, could temporarily affect the Company's performance 
adversely.  See "Year 2000 Compliance" above.

   The Company's subsidiaries currently buy a number of raw materials from 
single sources.  The failure of the subsidiaries to obtain sufficient raw 
materials or components as required, or to develop alternative sources if 
and as required in the future, could have a material adverse effect on the 
Company's business, financial condition and results of operations.

   The Company's operations are subject to a variety of laws, regulations 
and licensing requirements, including governmental regulations relating to 
the environment.  In addition, various pending or threatened legal 
proceedings by or against Oak or one or more of its subsidiaries involve 
alleged breaches of contract, torts and miscellaneous other causes of 
action.  The Company does not currently believe that its compliance with 
applicable regulations or any litigation against the Company will have a 
material adverse effect on the Company.  However, there can be no assurance 
that future compliance efforts or litigation will not have a material 
adverse effect on the Company's business, financial condition and results 
of operations.

ITEM 7A.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

   The Company is exposed to a variety of risks, including foreign currency 
fluctuations and changes in interest rates on its borrowings.  In the 
normal course of its business, the Company manages its exposure to these 
risks as described below.  The Company does not engage in trading market 
risk sensitive instruments for speculative purposes.

FOREIGN EXCHANGE

   During 1998, less than 20% of the Company's business was transacted in 
currencies other than the U.S. dollar.  From time to time, the Company 
enters into forward exchange contracts as a hedge against the foreign 
currency exchange risk on transactions denominated in foreign currencies.  
The Company has not entered into forward exchange contracts for speculative 
or trading purposes.  The Company has performed a sensitivity analysis 
assuming a hypothetical 10% adverse movement in foreign exchange rates.  As 
of December 31, 1998, the analysis demonstrated that such market movements 
would not have had a material adverse effect on the Company's consolidated 
financial position, results of operations or cash flows.  Actual gains and 
losses in the future may differ materially from this analysis, however, 
based on changes in the timing and amount of foreign currency rate 
movements and the Company's actual exposures.  The Company believes that 
its exposure to foreign currency exchange rate risk at December 31, 1998 
was not material.  See "Item 7. Management's Discussion and Analysis of 
Financial Condition and Results of Operations - Risks and Uncertainties."

INTEREST RATES

   As of December 31, 1998, the Company had outstanding borrowings that 
were subject to a floating interest rate.  The Company entered into 
interest rate swap agreements to manage its exposure to interest rate 
fluctuations on a portion of these borrowings.  These swap agreements 
provide for the exchange of floating rate for fixed interest payments 
periodically over the life of the agreements without any change to the 
underlying notional amounts.  Information about the Company's investments 
and interest rate swap agreements is set forth in Note 2 and Note 5 of the 
Notes to Consolidated Financial Statements, which are incorporated by 
reference herein.

   The Company has performed a sensitivity analysis assuming a hypothetical 
10% adverse movement in the floating interest rate on the borrowings 
described above.  As of December 31, 1998, the analysis demonstrated that 
such movement would not have a material adverse effect on the Company's 
consolidated financial position, results of operations or cash flows.  
Actual gains and losses in the future may differ materially from that 
analysis, however, based on changes in the timing and amount of interest 
rate movements and the Company's actual exposures.  The Company believes 
that it has minimal exposure to interest rate risk.  See "Item 7. 
Management's Discussion and Analysis of Financial Condition and Results of 
Operations - Risks and Uncertainties."

                REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of Oak Industries Inc.

   In our opinion, the consolidated financial statements listed in the 
accompanying index present fairly, in all material respects, the financial 
position of Oak Industries Inc. and its subsidiaries at December 31, 1997 
and 1998, and the results of their operations and their cash flows for each 
of the three years in the period ended December 31, 1998, in conformity 
with generally accepted accounting principles.  These financial statements 
are the responsibility of the Company's management; our responsibility is 
to express an opinion on these financial statements based on our audits.  
We conducted our audits of these statements in accordance with generally 
accepted auditing standards which require that we plan and perform the 
audit to obtain reasonable assurance about whether the 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, assessing the accounting principles used and significant 
estimates made by management, and evaluating the overall financial 
statement presentation.  We believe that our audits provide a reasonable 
basis for the opinion expressed above.

The accompanying Notes to Consolidated Financial Statements are an integral 
part of these consolidated statements.
<PAGE>

(1) NATURE OF BUSINESS: 

   Oak Industries Inc., together with its consolidated subsidiaries (the 
"Company"), is a leading manufacturer of highly-engineered components that 
it designs and sells to manufacturers and service providers in the 
communications and other selected industries.  

(2) STATEMENT OF ACCOUNTING POLICIES:

   Following are the significant financial and accounting policies of the 
Company:

Principles of Consolidation

   The consolidated financial statements include the accounts of the 
Company and all of its majority-owned subsidiaries.  All significant 
transactions between the Company and its subsidiaries are eliminated.

Pervasiveness of Estimates

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

Minority Interest

   Minority interest represents the minority stockholders' proportionate 
share of the equity and the net income of Connector Holding Company 
("Connector") and Gilbert Engineering Co., Inc. ("Gilbert") (see Note 3).

Investments in Affiliates

   The Company's investments in affiliates consist of: (1) a 50% interest 
in Wuhan Telecommunication Devices Co., a manufacturer of fiber-optic 
components in Wuhan, China; (2) a 49% interest in Teletec Corporation, a 
Japanese distributor of frequency control products; and (3) a 5% interest 
in TQ Electronics Co., Ltd., a Taiwanese distributor of frequency control 
products. 

Translation of Foreign Currencies

   The financial statements of foreign subsidiaries are translated into 
United States dollars in accordance with Statement of Financial Accounting 
Standards No. 52, "Foreign Currency Translation."  Translation adjustments, 
if any, are made directly to a separate component of stockholders' equity.  
Foreign currency transaction gains and losses are included in net income 
when realized and are insignificant.

Revenue Recognition

   Revenues from product sales are recognized at the time products are 
shipped.

Inventories

   Inventories are valued at the lower of cost ("first-in, first-out" 
basis) or market.  Inventory costs, which include material, labor and 
factory manufacturing overhead expenses, are as follows (dollars in 
thousands):

Plant and Equipment

   Plant and equipment are stated at cost.  Replacements and improvements 
are capitalized, while repairs and maintenance costs are charged to expense 
as incurred.  The Company expenses depreciation using the straight-line 
method over the following useful lives:

<TABLE>

</TABLE>

   The cost and accumulated depreciation of items sold or retired are 
removed from the plant and equipment accounts and any resulting profit or 
loss is recognized currently.

Intangible Assets 

   Goodwill and other intangibles, and the related amortization, are as 
follows (dollars in thousands):

</TABLE>

   Goodwill represents the excess of the cost of acquired businesses over 
the fair market value of their net tangible and identified intangible 
assets.  Goodwill is being amortized using the straight-line method over 
periods of 10 to 40 years.  Other intangibles are stated at cost and 
amortized using the straight-line method over periods of 3 to 15 years.  
Goodwill and other intangibles are assessed regularly to determine whether 
any potential impairment exists.  The Company assesses the potential 
impairment of goodwill and other identified intangible assets based on 
anticipated undiscounted cash flows from operations.

Capitalized Debt Costs

   The Company capitalizes all costs related to the issuance of debt.  The 
resulting capitalized debt costs  ($746,000 and $3,744,000 at December 31, 
1997 and 1998, respectively) are classified as "Other assets" on the 
consolidated balance sheet, and are amortized to expense using the 
straight-line method over the life of the related debt issue.  During 1996, 
1997 and 1998, the Company amortized $361,000, $152,000 and $473,000 
respectively, of capitalized debt costs.  As a result of terminating its 
previous debt facility, the Company wrote off capitalized debt costs of 
$1,531,000 in 1996 which are included in the extraordinary charge for early 
extinguishment of debt.

Income Taxes

   The provision for income taxes includes federal, foreign and state 
income taxes currently payable and those deferred because of temporary 
differences between the financial statement expenses and tax deductible 
expenses.  Deferred tax assets are recognized, utilizing current tax rates, 
for deductible temporary differences and operating loss and credit 
carryforwards that are more likely than not to be realized.  Deferred tax 
benefit or expense represents the change in the deferred tax asset or 
liability balances.

Research and Development

   Research and development costs, which are expensed as incurred, were 
$10,873,000, $12,647,000 and $13,520,000 in 1996, 1997 and 1998, 
respectively.  These costs are included in selling, general and 
administrative expenses in the consolidated statement of operations.

</TABLE>

   Options to purchase 50,000, 1,743,900 and 1,153,300 shares of common 
stock in 1996, 1997 and 1998, respectively, were outstanding at year end 
but were not included in the computation of diluted earnings per share 
because the exercise prices of the options were greater than the average 
market price of the common stock for the respective period.

Cash Equivalents

   The Company's cash equivalents represent funds invested in a variety of 
liquid short-term instruments with maturities of less than three months at 
time of purchase.  The carrying amount of these instruments approximates 
fair value. 

Investments

   The Company has classified certain debt securities, which are included 
in cash and cash equivalents, as held-to-maturity and certain debt and 
equity securities, which are included in other assets, as available-for-
sale.  Held-to-maturity securities are stated at cost, which approximates 
fair value, and associated interest is included in interest income.  
Available-for-sale securities are carried at fair value, with the 
unrealized gains and losses, net of tax, reported as a separate component 
of stockholders' equity.  Realized gains and losses and interest and 
dividends on available-for-sale securities are included in interest income.

Interest Rate Swap Agreements

   The Company enters into interest rate swap agreements in order to manage 
its exposure to interest rate fluctuations.  The swap agreements provide 
for the exchange of floating rate for fixed interest payments periodically 
over the life of the agreements without any change to the underlying 
notional amounts.  The interest rate swap agreements are used to measure 
interest to be paid or received and do not represent the amount of exposure 
to credit loss.  In the unlikely event that a counterparty fails to meet 
the terms of an interest rate swap agreement, the Company would be left 
with its original floating interest rate rather than the fixed rate it had 
anticipated.  The Company does not anticipate non-performance by any of the 
counterparties.  Net interest differentials to be paid or received related 
to interest rate swap agreements are accrued and ultimately recognized as 
an adjustment to interest expense over the life of the agreements.  The 
fair values of interest rate swap agreements are the estimated amounts that 
the Company would receive or pay to terminate the agreements at the 
reporting date, taking into account current interest rates and the current 
credit worthiness of the counterparty.

(3) ACQUISITIONS:

TELE QUARZ GMBH

   On October 30, 1998 the Company purchased 100% of the outstanding 
capital stock of Tele Quarz GmbH ("Tele Quarz").  Tele Quarz, located in 
Neckarbischofsheim, Germany, is a manufacturer of frequency control 
products.  The total purchase price for the capital stock and certain real 
estate, including debt assumed and transaction costs, was approximately 
$63.5 million.  

   Oak accounted for the acquisition as a purchase and, accordingly, 
included operating results of this business subsequent to the date of 
acquisition in the Company's consolidated financial statements.  The 
Company recorded $17,646,000 of goodwill and other intangibles associated 
with this acquisition.  The Company is amortizing the goodwill and other 
intangibles over 12 to 30 years.  During the fourth quarter of 1998, the 
Company charged $975,000 to cost of goods sold related to the purchase 
accounting for Tele Quarz's inventory.

   The following unaudited pro forma summary combines the consolidated 
results of operations of the Company and Tele Quarz as if the acquisition 
had occurred at the beginning of 1997, after giving effect to certain 
adjustments, including amortization of intangible assets, increased 
interest expense on the acquisition debt, purchase accounting for 
inventory, and related income tax effects.  The pro forma summary does not 
necessarily reflect the results of operations as they would have been if 
the Company and Tele Quarz had constituted a single entity during such 
periods (dollars in thousands, except per share amounts):

PIEZO CRYSTAL COMPANY

   On September 30, 1997, the Company acquired all of the outstanding 
capital stock of Piezo Crystal Company ("Piezo"), a Carlisle, Pennsylvania 
manufacturer of frequency control products for the satellite and wireless 
communications industries.  The Company initially paid approximately 
$20,200,000 in cash, including transaction expenses.  The purchase price 
was financed with borrowings from the Company's credit facility.  The 
acquisition was accounted for as a purchase.  During the fourth quarter of 
1997, the Company charged $615,000 to cost of goods sold related to the 
purchase accounting for Piezo's inventory.  In April 1998, Piezo's selling 
shareholders received additional consideration of $1,000,000 based on 
Piezo's fourth quarter 1997 performance.  The additional $1,000,000 earned 
by Piezo's selling shareholders was recorded by the Company as of December 
31, 1997 and is included in goodwill and accrued liabilities.  The Company 
recorded approximately $13,700,000 of goodwill that is being amortized over 
40 years.  Pro forma results of operations have not been presented because 
the effects of the acquisition were not significant.

CONNECTOR AND GILBERT MINORITY INTEREST

   On November 1, 1996, the Company purchased the 20% interest in Connector 
owned by certain affiliates of Bain Capital, Inc. ("Bain") for 
approximately $95,000,000 in cash, including transaction expenses.  
Connector owned 85% of Gilbert, and as a result of the acquisition the 
Company acquired Bain's 17% indirect interest in Gilbert.  Oak accounted 
for the acquisition as a purchase and accordingly there is no minority 
interest expense related to Bain in the Company's consolidated financial 
statements subsequent to the date of acquisition.  Goodwill of 
approximately $72,000,000 resulting from this acquisition is being 
amortized over 36 years, which is consistent with the remaining period 
relating to goodwill resulting from the purchase of an 80% equity interest 
in Connector during 1992.  The purchase was financed with borrowings from 
the Company's credit facility.

   The following unaudited pro forma summary combines the consolidated 
results of operations of the Company as if the acquisition of the Bain 
interest had occurred at the beginning of 1996, after giving effect to 
certain adjustments, including amortization of intangible assets, increased 
interest expense and related income tax effects.  The pro forma summary 
does not necessarily reflect the results of operations as they would have 
been if the Company had acquired the Bain interest during such period 
(dollars in thousands, except per share amounts):

</TABLE>

   On November 15, 1996, the Company agreed to purchase the 15% equity 
interest in Gilbert owned by certain members of the management of Gilbert 
(the "Selling Stockholders").  The Company purchased 7.5% of Gilbert from 
the Selling Stockholders in the fourth quarter of 1996 at a purchase price 
of approximately $30,600,000.  The Company financed the acquisition with 
borrowings from its credit facility and accounted for the acquisition as a 
purchase and, accordingly, there is no minority interest expense related to 
the portion purchased from the Selling Stockholders in the Company's 
consolidated financial statements subsequent to the date of acquisition.  
Goodwill of approximately $20,000,000 resulting from this acquisition is 
being amortized over 36 years.  Pro forma results of operations have not 
been presented for the acquisition of 7.5% of Gilbert because the effects 
of the acquisition were not significant.

   On October 31, 1997, the Company purchased 3.75% of Gilbert held by the 
Selling Stockholders for approximately $8,800,000 in cash.  The purchase 
price was financed with borrowings from the Company's credit facility and 
with cash generated from operations.  Oak accounted for this acquisition as 
a purchase and, accordingly, there is no minority interest expense related 
to the portion purchased from the Selling Stockholders in the Company's 
consolidated financial statements subsequent to the date of the 
acquisition.  Goodwill of approximately $4,000,000 resulting from this 
acquisition is being amortized over 35 years.  The Company owned 96.25% of 
Gilbert at December 31, 1997.  Pro forma results of the 3.75% acquisition 
are not presented because the effects of the acquisition were not 
significant.

   On October 30, 1998, the Company purchased the remaining 3.75% of 
Gilbert held by the Selling Stockholders, resulting in the Company's 100% 
ownership of Gilbert.  The Company paid approximately $11,400,000 in cash.  
The Company financed the purchase price with borrowings from its credit 
facility and with cash generated from operations.  The Company accounted 
for this acquisition as a purchase and, accordingly, there is no minority 
interest expense related to the portion purchased from the Selling 
Stockholders in the Company's consolidated financial statements subsequent 
to the date of the acquisition.  Goodwill of approximately $6,857,000 
resulting from this acquisition is being amortized over 34 years.  Pro 
forma results of this final acquisition are not presented because the 
effects of the acquisition were not significant.

(4) DIVESTITURES:

   During 1998, the Company sold its 50% interest in McCoy (Cayman) Ltd. 
and McCoy International and received net proceeds of $898,000.  The Company 
recorded a pre-tax gain of $772,000 from the sale.

   During 1996, the Company sold its 49% interest in Video 44 (WSNS-TV 
Channel 44), and received net proceeds of $29,400,000.  The Company 
recorded a pre-tax gain of $20,550,000 from the sale.  

   During 1996, the Company completed the sale of its 45% interest in O/E/N 
India Ltd. for $1,471,000 in cash.  As a result of this sale the Company 
reported a pre-tax gain of $952,000.

   During 1996, the Company sold its Nordco Inc. ("Nordco")  subsidiary to 
an affiliate of Banc One Venture Corporation and members of Nordco 
management for net cash proceeds of approximately $19,381,000.  The Company 
reported a gain of $9,367,000 from the sale in 1996.  Because the tax basis 
of Nordco was greater than the sales price, the Company did not pay income 
taxes or record an income tax provision related to this transaction.

   As a result of the sale of Nordco, the Company has restated its prior 
year consolidated financial statements to reflect Nordco as a discontinued 
operation.  The results of the discontinued operations reflected in the 
consolidated statements of operations are as follows (dollars in 
thousands):

</TABLE>

   On February 25, 1998, the Company issued $100,000,000 of 4 7/8% 
Convertible Subordinated Notes due 2008 (the "Notes").  The Notes are 
convertible into common stock of the Company at a conversion price of 
$38.66 per share.  Interest on the Notes is payable semi-annually in 
arrears on each March 1 and September 1, and the first interest payment was 
made on September 1, 1998.  The net proceeds from the sale of the Notes 
were used to reduce borrowings under the Company's $300,000,000 revolving 
credit facility.

   On November 1, 1996, the Company entered into a credit agreement with 
various lenders that provides for a $300,000,000 revolving credit facility 
(the "Facility").  During 1996, proceeds of $125,000,000 from the Facility 
were used to purchase the minority interest of Gilbert and $21,000,000 was 
used to refinance existing indebtedness of the Company.  During 1997, the 
Facility was used for the repurchase of Company stock, the Piezo 
acquisition, and the purchase of additional interests in Gilbert.  During 
1998, proceeds from the Facility were used for the repurchase of Company 
stock, the Tele Quarz acquisition and the final purchase of minority 
interests in Gilbert.

   The Company's previously existing $200,000,000 credit agreement was 
terminated on November 1, 1996.  As a result, the Company recorded non-
cash, after tax, and other minority interest charges of $949,000 in 1996 
related to the early extinguishment of the former credit facility.

   Borrowings under the Facility bear interest, at the option of the 
Company, either (i) at the prime rate (or, if higher, at 0.5% above the 
federal funds rate) or (ii) at a spread ranging from 0.5% to 1.25% over the 
reserve-adjusted 1, 2, 3, or 6 month LIBOR.  The spread is subject to 
adjustment based on certain financial tests. As of December 31, 1998, 
interest rates on outstanding borrowings under the Facility ranged from 
6.06% to 7.75%.  Commitment fees ranging from 0.175% to 0.35% are payable 
on unused borrowings under these agreements.  Certain of the Company's 
subsidiaries have guaranteed the obligations under the Facility.  Pursuant 
to the Facility's terms, Oak Industries Inc. is required to meet certain 
financial covenants and is prohibited from paying dividends.  The Facility 
will be reduced by $50,000,000 on each of November 1, 1999 and November 1, 
2000 and matures on December 31, 2001.

   Other long-term debt consists of mortgages and leases with maturities 
through 2008 and fixed rates ranging from 6.0% to 8.2%.  These obligations 
are secured by the related land, building, machinery and equipment.

   Scheduled payments of long-term debt at December 31, 1998 are as follows 
(dollars in thousands):

</TABLE>

   As of December 31, 1998, the Company had exchanged its floating rate 
obligation on (i) a $25,000,000 notional principal amount for a fixed rate 
payment obligation of 6.02% (plus a spread of 0.5% to 1.25%) per annum 
through December 24, 1999; and (ii) a $25,000,000 notional principal amount 
for a fixed rate payment obligation of 6.02% (plus a spread of 0.5% to 
1.25%) per annum through December 27, 2000.  The Company charged $26,000 
and $125,000 to interest expense related to these interest rate swap 
agreements for 1997 and 1998, respectively.  The Company estimates that as 
of December 31, 1998, the cost to terminate the agreements would have been 
$721,000.

(6) CAPITAL STOCK:

SHAREHOLDERS' RIGHTS PLAN

   On December 7, 1995 the Company's Board of Directors adopted a 
shareholders' rights plan.  The Board declared a distribution of one right 
for each share of common stock outstanding on December 18, 1995.  Stock 
issued after that date is issued with an attached right.  Each right 
entitles the holder, upon the occurrence of certain events, to purchase 
1/100th of a share of junior preferred stock at an initial exercise price 
of $125.  The Board may, at any time, redeem the rights until their 
expiration on December 7, 2005, and may amend the rights under certain 
circumstances until they become exercisable.

STOCK PURCHASE LOANS

   In connection with a secondary offering of its stock in December 1993, 
the Company lent $1,305,000 to corporate officers and certain key 
divisional managers to finance their purchase of 90,000 shares of the 
Company's stock from selling shareholders.  The principal amount of the 
remaining loan is repayable in full on January 1, 2000.  Interest on this 
loan is calculated quarterly, based on the interest rate applicable to the 
Company's outstanding debt, and is payable annually until maturity.  The 
loan, which is included in stockholders' equity, is secured by the common 
stock that was purchased and certain other amounts owed to such individual 
by the Company.  In 1996, principal of $285,000 was paid to the Company by 
the borrowers.  In 1996, 1997 and 1998, respectively, interest of $55,000, 
$20,000 and $17,000 was paid to the Company by the borrowers.  The 
principal balance of the remaining loan at December 31, 1997 and 1998 was 
$262,000.

STOCK REPURCHASE

   In December 1996, the Company was authorized to expend up to $50.0 
million to repurchase shares of its common stock on the open market.  In 
October 1998, this program was amended to allow stock repurchases not to 
exceed $75.0 million in the aggregate.  As of December 31, 1998, the 
Company had spent $35.1 million to repurchase 1,602,200 shares of its 
common stock.  

(7) STOCK OPTIONS AND AWARDS:

   The Company has award plans for directors, officers, employees, 
consultants and advisors, which provide for, among other things, the 
issuance of stock options and restricted stock.  With respect to stock 
options, the Compensation Committee of the Company's Board of Directors 
determines the option price (not to be less than fair market value) at the 
date of the grant.  Options granted pursuant to the Company's award plans 
generally vest over three years from the date of the grant and expire after 
ten years or ten years and one day.  Certain options granted under the 1995 
Stock Option and Restricted Stock plan were originally exercisable prior to 
the tenth anniversary of their grant date only if the Company's common 
stock closed at or above 150% of the grant date price for ten consecutive 
trading days within the three year period following the grant date.  On 
December 4, 1996, the Board of Directors approved an amendment to the 
exercisability terms of these options.  As a result, options for the 
purchase of 550,000 of the Company's shares were amended in order to 
provide for their exercisability over a period of 3 years from their 
original grant date.

   During 1996 and 1997, the Company granted 124,000 and 5,000 shares, 
respectively, of restricted stock from the 1995 Stock Option and Restricted 
Stock Plan (the "1995 Plan") to certain of its officers and employees.  
These shares vest on the third anniversary of the date of grant provided 
that the recipient is still employed by the Company.  During 1997, 25,000 
shares of the restricted stock were forfeited.  The market value of the 
restricted stock awarded to certain officers and employees totaled 
$2,945,000 and $133,000 in 1996 and 1997, respectively, and these amounts 
have been recorded as a separate component of stockholders' equity.  The 
Company granted no restricted stock under the 1995 Plan in 1998.  The 
Company amortizes unearned compensation to expense over the three-year 
vesting period.

   The Company has elected to follow Accounting Principles Board Opinion 
No. 25, "Accounting for Stock Issued to Employees" ("APB 25") and related 
interpretations in accounting for its employee stock options.  Under APB 
25, because the exercise price of the Company's employee stock options 
equals the market price of the underlying stock on the date of grant, no 
compensation expense is recognized.  The Company has adopted the 
disclosure-only provisions of Statement of Financial Accounting Standards 
No. 123 ("SFAS No. 123"), "Accounting for Stock-Based Compensation."

   The following table summarizes information about the Company's stock 
option activity for the years ended December 31, 1996, 1997, and 1998.

   Pro forma information regarding net income and earnings per share is 
required by SFAS No. 123, and has been determined as if the Company had 
accounted for its employee stock options under the fair value method of 
that statement.  The fair value for these options was estimated at the date 
of grant using a Black-Scholes option pricing model with the following 
weighted-average assumptions:  risk-free interest rates in the range of 
5.4% to 7.9%, 4.8% to 6.9% and 4.2% to 5.7% in 1996, 1997 and 1998, 
respectively; volatility factors of the expected market price of the 
Company's common stock of .72, .56 and .45 in 1996, 1997 and 1998, 
respectively; and an expected life of the option of 6 years.  The weighted-
average fair values of options granted were $18.40, $15.23 and $17.10 per 
share in 1996, 1997 and 1998, respectively.

   For purposes of pro forma disclosures, the estimated fair value of the 
options is amortized to expense over the options' vesting periods.  The 
Company's pro forma information follows (in thousands except for earnings 
per share information):

(8) POSTRETIREMENT BENEFITS:

   The Company has three noncontributory pension plans covering certain of 
its employees.  Benefits under the plans are generally based on years of 
service and employees' compensation during the last years of employment or 
a specified dollar benefit.  It is the Company's policy to fund at least 
the minimum amount required by the Employee Retirement Income Security Act 
of 1974, as amended, for each plan.

   In 1996, the Company curtailed one of its plans as a result of reduced 
employment levels and plan amendments.  This curtailment resulted in a gain 
of $139,000 in 1996.   

   The projected benefit obligation was determined using an assumed 
discount rate of 7.25% for 1997 and 6.75% for 1998.  The expected long-term 
rate of return on plan assets was 10% for 1997 and 1998.  

   The assets of the defined benefit plans at December 31, 1997 and 1998 
consist principally of common stocks, bonds and cash equivalents. 

   The Company has defined contribution plans covering all full-time 
employees who meet certain eligibility requirements.  Contributions by the 
Company and the employees are determined according to salary-based 
formulas.  The Company recognized expense related to these plans of 
$2,422,000, $2,453,000 and $2,527,000 in 1996, 1997 and 1998, respectively.

   In 1993, the Company established a non-qualified supplemental retirement 
plan for certain employees.  Under the plan, participants may elect to 
contribute up to 15% of their annual salary and bonus and the Company makes 
matching contributions in the form of shares of the Company's common stock 
having a value equal to 50% of participants' contributions.  The Company's 
matching contributions vest on the third anniversary of a participant's 
enrollment in this plan provided the participant remains employed by the 
Company through that date.  Upon termination of employment, participants 
receive the fair value of their account for the employee-contribution 
portion in cash and shares of the Company's common stock for the vested 
portion of the Company's matching contribution.  Contributions by the 
employees currently earn interest at the yield for three year U.S. Treasury 
Notes, adjusted annually.  The Company recorded expense of $431,000, 
$400,000 and $419,000 in 1996, 1997 and 1998, respectively, related to this 
plan.

   In connection with the acquisition of Tele Quarz in October 1998, the 
Company recorded deferred tax assets in the amount of approximately 
$1,582,000. 

   The decrease in the gross deferred tax assets from 1997 to 1998 results 
primarily from the utilization of the Company's tax credit carryforwards.

   The following table displays the differences between income tax 
provision and the amount of income tax that would result by applying the 
applicable U.S. statutory federal income tax rate to income from continuing 
operations before income taxes, minority interest and extraordinary charge 
(dollars in thousands):

   At December 31, 1998, the Company had no net operating loss 
carryforwards for federal tax reporting purposes.  The Company had foreign 
tax credit carryforwards of approximately $630,000 at December 31, 1998 
that, if unused, will expire from 2000 to 2001.  Realization of the credit 
carryforwards is dependent on generating sufficient taxable income prior to 
the expiration of the credits.  Although realization is not assured, the 
Company believes it is more likely than not that all of the deferred tax 
assets will be realized.  Undistributed earnings of certain foreign 
subsidiaries and of certain foreign equity method investees of the Company 
are considered to be indefinitely reinvested.  Accordingly,  no provision 
for U.S. federal and state income taxes has been provided for these 
unremitted earnings.

(10) SEGMENT INFORMATION:

   The Company's reportable segments are business units that offer 
different products.  The Company has four reportable segments:  the Cable 
Broadband Products Segment, which manufactures coaxial connector products 
used primarily in the CATV industry; the Frequency Control Products 
Segment, which manufactures quartz-based crystals and oscillators for 
wireless base stations and telecommunications applications; the Fiber-Optic 
Products Segment, which manufactures fiber-optic components primarily used 
in wired telephony networks; and the Controls Products Segment, which 
manufactures components for gas ranges, and switches and encoders used in a 
variety of applications.

   Reported segment income is operating income and equity in net income 
(loss) of affiliated companies directly attributable to the segment, 
adjusted for minority interest in income before income taxes of 
subsidiaries.  Operating income is before corporate expenses, interest, and 
unusual transactions.  Equity in net income (loss) of affiliated companies 
is before unusual transactions.  Segment assets are all assets directly 
attributable to the segment, excluding goodwill and other intangible 
assets, deferred income taxes and investment in affiliates.  The accounting 
policies for the segments are the same as those described in the statement 
of accounting policies.

   Summarized financial information concerning the Company's reportable 
segments is shown in the following table:

(13) COMMITMENTS AND CONTINGENCIES:

   The Company incurred rent expense for facilities and office equipment of 
$4,601,000, $3,970,000 and $4,296,000 in 1996, 1997 and 1998, respectively.  
At December 31, 1998, the Company was committed under non-cancellable 
operating leases for minimum annual rentals for the next five years as 
follows:  1999 - $4,260,000; 2000 - $3,814,000; 2001 - $3,260,000; 2002 - 
$2,494,000; 2003 - $1,547,000; thereafter - $7,835,000.

   Various pending or threatened legal proceedings by or against the 
Company or one or more of its subsidiaries involve alleged breaches of 
contract, torts and miscellaneous other causes of action.  The Company does 
not consider any of such proceedings to be material to the Company's 
financial position, results of operations, or liquidity.  In January 1997 
the Company discovered that the controller at one of its divisions had 
improperly capitalized expenses that should have been expensed during the 
periods in which they were incurred.  The Company filed amended Form 10-Qs 
for the first three quarters of 1996 during February 1997 to correct these 
errors.  The Company is voluntarily cooperating with the Securities and 
Exchange Commission (the "SEC") on an informal basis with respect to 
inquiries by the SEC concerning these matters.

with the Company at the time of such award.

Section 3.2 - Granting of Options to Participants

consistent with the Plan.

ARTICLE IV

Section 4.3 - Commencement of Exercisability

each individual Option; provided, however, that by resolution adopted after 
an Option is granted the Committee may, on such terms and conditions as it 
may determine to be appropriate, accelerate the time at which such Option 
or any portion thereof may be exercised.

Section 4.4 - Expiration of Options

   The Committee shall provide, either at the time of grant or any time 
thereafter, in the terms of each individual Option, when such Option 
expires and becomes unexercisable; and (without limiting the generality of 
the foregoing) the Committee may provide in the terms of individual Options 
that said Options expire immediately upon a Termination of Service for any 
reason.

Section 4.5 - Employment/Business Relationship

   Nothing in this Plan or in any stock option agreement hereunder shall 
confer upon any Participant any right to continue in the employ of, or 
maintain a business relationship with, the Company, any Parent Corporation 
or any Subsidiary or shall interfere with or restrict in any way the rights 
of the Company, its Parent Corporations and its Subsidiaries, which are 
hereby expressly reserved (subject to applicable agreements specifically to 
the contrary), to discharge any Participant, or terminate at such 
relationship, at any time for any reason whatsoever, with or without cause.

Section 4.6 - Merger, Consolidation, Acquisition, Liquidation or 
Dissolution

   In the event of the merger or consolidation of the Company with or into 
another corporation as a result of which the Stock is no longer 
outstanding, the acquisition by another corporation or person of all or 
substantially all of the Company's assets or 50% or more of  the Company's 
then outstanding voting stock, or the liquidation or dissolution of the 
Company, all outstanding Options shall become immediately exercisable on 
the 45th day prior to the proposed effective date of any such merger, 
consolidation, acquisition, liquidation or dissolution.  Immediately prior 
to the consummation of such merger, consolidation or sale of assets all 
outstanding Options shall terminate unless the Committee shall have 
arranged that the surviving or acquiring corporation or an affiliate of 
that corporation assume the Options or grant to Participants replacement 
Options.

ARTICLE V

EXERCISE OF OPTIONS

Section 5.1 - Person Eligible to Exercise

   During the lifetime of the Participant, only the Participant or the 
Participant's permitted transferees may exercise an Option granted to such 
Participant, or any portion thereof.  After the death of the Participant, 
any exercisable portion of any Option may, prior to the time when such 
portion becomes unexercisable, be exercised by the Participant's personal 
representative or by any person empowered to do so under the deceased 
Participant's will or under the then applicable laws of descent and 
distribution.

Section 5.2 - Partial Exercise

   At any time and from time to time prior to the time when any exercisable 
Option or exercisable portion thereof becomes unexercisable, such Option or 
portion thereof may be exercised in whole or in part; provided, however, 
that the Company shall not be required to issue fractional shares and the 
Committee may, by the terms of the Option, require any partial exercise to 
be with respect to a specified minimum number of shares.

Section 5.3 - Manner of Exercise

   An exercisable Option, or any exercisable portion thereof, may be 
exercised solely by delivery to the Secretary or the Secretary's office of 
all of the following prior to the time when such Option or such portion 
becomes unexercisable:

         (a)      Notice in writing signed by the Participant or other 
person then entitled to exercise such Option or portion, stating that such 
Option or portion is exercised, such notice complying with all applicable 
rules established by the Committee; and

         (b)      Full payment for the shares of Stock with respect to 
which such Option or portion is thereby exercised by:

(i)      cash or by check; or

               (ii)      shares of Stock owned by the Participant (which in 
the case of Stock acquired from the Company, shall have been held for at 
least six months) duly endorsed for transfer to the Company with a Fair 
Market Value on the date immediately prior to the date of delivery equal to 
the aggregate Option price; or

               (iii)   with the consent of the Committee, a full recourse 
promissory note bearing interest (at a rate at least sufficient to preclude 
the imputation of interest under the Code or any successor provision) and 
payable upon such terms as may be prescribed by the Committee.  The 
Committee may also prescribe the form of such note and the security to be 
given for such note.  No Option may, however, be exercised by delivery of a 
promissory note or by a loan from the Company when or where such loan or 
other extension of credit is prohibited by law; or

               (iv)      delivery of an unconditional and irrevocable 
undertaking by a broker to deliver promptly to the Company sufficient funds 
to pay the exercise price; or

               (v)      any combination of the consideration provided in 
the foregoing subsections (i), (ii), (iii), and (iv); and

         (c)   Such representations and documents as the Committee, in its 
absolute discretion, deems necessary or advisable to effect compliance with 
all applicable provisions of the Securities Act and any other federal or 
state securities laws or regulations.  The Committee may, in its absolute 
discretion, also take whatever additional actions it deems appropriate to 
effect such compliance including, without limitation, placing legends on 
share certificates and issuing stop-transfer orders to transfer agents and 
registrars; and

         (d)   In the event that the Option or portion thereof shall be 
exercised by any person or persons other than the Participant, appropriate 
proof of the right of such person or persons to exercise the Option or 
portion thereof.

Section 5.4 - Conditions to Issuance of Stock Certificates

   The Company shall not be required to issue or deliver any certificate or 
certificates for shares of Stock purchased upon the exercise of any Option 
or portion thereof prior to fulfillment of all of the following conditions:

         (a)   The admission of such shares to listing on all stock 
exchanges on which the Stock is then listed; and

         (b)   The completion of any registration or other qualification of 
such shares under any state or federal law or under the rulings or 
regulations of the Securities and Exchange Commission or any other 
governmental regulatory body, which the Committee shall, in its absolute 
discretion, deem necessary or advisable; and

         (c)   The obtaining of any approval or other clearance from any 
state or federal governmental agency which the Committee shall, in its 
absolute discretion, determine to be necessary or advisable; and

         (d)   The payment to the Company of all amounts which it, any 
Parent Corporation or any Subsidiary is required to withhold under federal, 
state or local law in connection with the exercise of the Option.  If 
permitted by the Committee, either at the time of the grant of the option 
or at the time of exercise, the Participant may elect at such time and in 
such manner as the Committee may prescribe, to satisfy such withholding 
obligation by (i) delivering to the Company Stock owned by such individual 
having a Fair Market Value on the day immediately prior to the date of 
delivery equal to such withholding obligation, or (ii) requesting that the 
Company withhold from the shares of Stock to be delivered upon exercise of 
such option a number of shares of Stock having a Fair Market Value on the 
date immediately prior to the date of delivery equal to such withholding 
obligation; and

         (e)   The lapse of such reasonable period of time following the 
exercise of the Option as the Committee may establish from time to time for 
reasons of administrative convenience.

Section 5.5 - Rights as Shareholders

   The holders of Options shall not be, nor have any of the rights or 
privileges of, shareholders of the Company in respect of any shares 
purchasable upon the exercise of any part of an Option unless and until 
certificates representing such shares have been issued by the Company to 
such holders.

Section 5.6 - Transfer Restrictions

   Except as the Committee may otherwise provide, an Option granted under 
the Plan is personal to the Participant and is not transferable by the 
Participant in any manner other than by will or the laws of descent and 
distribution.  The Committee, in its absolute discretion, may impose such 
other restrictions on the transferability of the shares purchasable upon 
the exercise of an Option as it deems appropriate.  Any such restriction, 
as well as any requirement to notify the Committee of the disposition of 
such shares, shall be set forth in the respective stock option agreement 
and may be referred to on the certificates evidencing such shares.

ARTICLE VI

ADMINISTRATION

Section 6.1 - Duties and Powers of Committee

   It shall be the duty of the Committee to conduct the general 
administration of the Plan in accordance with its provisions.  The
