                                     PART I

ITEM 1. BUSINESS

Introduction

         Blonder Tongue Laboratories, Inc. (the "Company") is a designer,
manufacturer and supplier of a comprehensive line of electronics and systems
equipment for the non-franchised cable television industry, commonly referred to
as the private cable industry ("Private Cable") and the franchised cable
industry ("CATV") which now potentially includes the regional and long distance
telephone service providers. The Company's products are used in the acquisition,
conversion, distribution and protection of television signals transmitted via
satellite, coaxial cable, terrestrial broadcast, terrestrial multi-channel,
multi-point distribution systems and low power television. These products are
sold to customers which provide an array of communications services, including
television, to single family dwellings, multiple dwelling units ("MDU")
consisting mainly of apartment complexes and condominiums, the lodging industry
("Lodging") consisting mainly of hotels, motels and resorts, and other
facilities such as schools, hospitals, prisons and marinas. The Company's
products are also used in surveillance systems ranging in complexity from simple
in-home monitoring systems to advanced business security systems with hundreds
of cameras.

         Blonder Tongue's product line can be separated, according to function,
into the following categories: (i) headend products used by a system operator
for signal acquisition, processing and manipulation for further transmission
("Headend Products"), (ii) distribution products used to permit signals to
travel to their ultimate destination in a home, apartment unit, hotel room,
office or other terminal location ("Distribution Products"), (iii) subscriber
products used to control access to programming at the subscriber's location and
to split and amplify incoming signals for transmission to multiple sites and for
multiple television sets within a site ("Subscriber Products"), and (iv)
microwave products used to transmit the output of Headend Products to multiple
locations using point-to-point communication links in the 13 GHz (for CATV) and
18 GHz (for Private Cable) range of frequencies ("Microwave Products").

         The Company's principal customers are system integrators which design,
package, install and in most instances operate the cable system.

                                       -2-

<PAGE>

         On March 26, 1998, the Company acquired all of the assets and
technology rights of the interdiction business (the "Interdiction Business") of
Scientific-Atlanta, Inc. ("Scientific") for a purchase price consisting of (i)
$19 million in cash, (ii) 67,889 shares of the Company's common stock, (iii) a
warrant to purchase 150,000 additional shares of the Company's common stock at
an exercise price of $14.25 per share and (iv) assumption by the Company of
certain obligations under executory contracts with vendors and customers and
certain warranty obligations and other current liabilities of the Interdiction
Business. The Interdiction Business generated approximately $16 million in
revenues for the prior twelve month period. The Company believes that
Scientific's interdiction products, which have been engineered primarily to
serve the franchised cable market, will supplement the Company's VideoMask(TM)
products, which are primarily focused on the Private Cable market. In addition,
the Company expects that the technology acquired as part of the Interdiction
Business will enhance its ability to design products that meet the specific
needs of all cable providers, while improving its position in the franchised
cable market. Scientific will provide certain manufacturing, consulting and
other transition services to the Company during a limited period following the
acquisition pursuant to agreements executed by the parties in order to permit
the Company to fulfill sales orders of the Interdiction Business for the
transition period following the closing.

         In addition, under the terms of the purchase agreement with Scientific,
the Company is obligated to file a registration statement with the Securities
and Exchange Commission to register the shares of common stock issued to
Scientific and underlying the warrant held by Scientific as part of the purchase
price for the Interdiction Business within 90 days after the closing of the
acquisition.


Industry Overview

         The television signal distribution industry is dominated by broadcast
television and CATV. Private Cable, wireless cable and direct broadcast
satellite, although smaller in market size, are becoming more significant
players and are growing more rapidly. The regional telephone companies and long
distance carriers are also emerging as television providers, through telephone
lines, coaxial cable, fiber optics and/or wireless transmission. Recently
enacted governmental deregulation of the communications industry has eliminated
many remaining barriers to entry by alternative service providers, fostering an
environment of greater competition and change.

         CATV service is typically provided through a coaxial cable network or a
combination of optical fiber and coaxial cable that originates from a central
headend and is carried to the subscriber's television set on telephone poles or
underground along utility rights-of-way. Since the installation and maintenance
of this network requires substantial initial and ongoing investment, a local
governmental body typically awards a CATV operator rights to provide cable
service to a defined geographic area. These rights or franchises were awarded on
an exclusive basis prior to the adoption of the Telecommunications Act of 1996.
Presently, additional franchises within geographical areas are encouraged, in
order to increase competition. In contrast, Private Cable operates within the
boundaries of private property, does not require any governmental license or
franchise (other than the FCC license for transmission of television signals in
the 18 GHz frequency band), and does not need access to public or private
rights-of-way to deliver service. In Private Cable, television signals are
acquired and transmitted from property to property via wireless transmission or
using common carrier services (i.e. fiber networks operated by telephone service
providers) rather than coaxial cable.

         The traditional CATV customer is a homeowner who is likely to remain in
the same home as a long-term subscriber. For a wide variety of reasons,
including the transient nature of apartment dwellers and the high cost of
replacing lost or damaged set-top converters in apartment units when the tenants
change, CATV has failed to adequately service the MDU market. This failure,
together with the ability of Private Cable operators to link multiple properties
to a central headend system, have greatly expanded the potential market for
Private Cable. Present franchise cable operators recognizing the competition of
private cable, anticipating direct

                                       -3-

<PAGE>

competition by telephone service providers, and faced with employing even more
costly in-house converters (i.e. as digital service is added) realize the
vulnerability of the set top concept and the need to expand services to retain
subscribers.

         CATV

         Many CATV operators and telephone service providers are building fiber
optic networks with alternative combinations of fiber optic and coaxial cable to
deliver television signal programming data and phone services on one drop cable.
CATV's deployment of fiber optic trunk has been completed in only 10% to 20% of
existing systems. Deployment of the latest technology is in the test system
stage. The system architecture being employed to accomplish the combined
provision of television and telephone service is either hybrid fiber coax
("HFC") or fiber to the curb ("FTTC"). In HFC systems, fiber optic trunk lines
connect to nodes which feed 200 to 400 subscribers, using coaxial cable. In FTTC
systems fiber optic cable is used deeper into the network, with as few as four
to eight subscribers fed by coaxial cable from each node. In either case,
extensive rebuilding of a CATV system is required to provide the services
anticipated. Consequently, not only are the regional and long distance telephone
service providers faced with enormous capital expenditures to enter the video
signal delivery business, but CATV is faced with similar expenditures to compete
with them (or to discourage them from entering the race) to be the provider of
the information superhighway.

         The Company believes that most major metropolitan areas will eventually
have complex networks of one or two independent operators interconnecting the
homes and private cable operators will have large networks interconnecting many
multi-dwelling complexes. All these networks are potential users of Blonder
Tongue Headend and interdiction products.

         MDU

         Until February, 1991, the ability of Private Cable operators to
penetrate the MDU market was substantially limited by FCC rules which
specifically prohibited the Private Cable operator from using coaxial cable
connections between properties. CATV operators had a significant competitive
advantage because they could connect properties within their franchised areas
with coaxial cable. In an effort to level the playing field, the FCC designated
special frequency bands enabling Private Cable operators to link multiple
properties to one central headend system via microwave signal transmission,
thereby spreading the cost of headend electronics over multiple MDUs and a wider
potential subscriber base. This new 18 GHz service is wide enough to support the
transmission of 72 channels of television programming, has been the catalyst
fueling the growth and product investment of MDU system operators, and has
caused a substantial increase in the demand for quality Headend Products. In
addition, provisions of the Telecommunications Act of 1996 permit Private Cable
system operators to use coaxial cable connections between adjacent properties
where no access to public rights-of-way are required. Further, fiber optic
networks built by regional and long distance telephone service providers, which
are common carriers, could be used by Private Cable system integrators as
interconnects.

         Through the use of Microwave Products and common carrier fiber optic
networks, Private Cable operators can target geographic areas with multiple
properties, many of which would not otherwise have been considered economically
feasible, for inclusion as part of an extensive Private Cable network. In the
past, properties with 100 to 200 subscribers, could not financially justify more
than 15 to 20 channels, but can now be linked to a central headend and justify a
high channel carrier service of 60 channels or more. This allows Private Cable
operators to supply a wide variety of programming at a price which is
competitive with CATV.

         The economic feasibility of a Private Cable system depends on
controlling the headend cost and spreading that cost over as many subscribers as
possible using microwave links to multiple MDUs. Electronic equipment providing
the best possible performance-to-cost ratio is key to successfully providing for
the needs of

                                       -4-

<PAGE>

Private Cable operators. The Company believes that its products are
cost-effective and competitive with the products of other companies supplying
the CATV industry, in terms of quality, number of channels and price.

         Lodging

         Until the early 1990's, one system integrator dominated the Lodging
market and manufactured much of its own equipment. During the last several
years, other Private Cable integrators have successfully entered and expanded
the Lodging market by offering systems with more channels, video-on-demand and
interactivity. These systems have been well received in the market, as property
owners have sought additional revenues and guests have demanded increased
in-room conveniences. The integrators leading this market evolution rely upon
outside suppliers for their system electronics and are Blonder Tongue customers.
These companies and others offer Lodging establishments VCR-based systems which
provide true video-on-demand movies with a large selection of titles. To meet
these demands, the typical Lodging system headend will include as many as 20 to
40 receivers and as many as 60 to 80 modulators, and will be capable of
providing the guest with more channels free-to-guest, video-on-demand for a
broad selection of movie titles and even interactive services such as remote
check-out and concierge services. This is in contrast to the systems which
preceded them which had typically 10 to 12 receivers and modulators and provided
six to ten channels free-to-guest and two to five channels of VCR-based movies
running at published scheduled times.

         There is a trend to substitute video file servers for VCRs, which the
Company believes will eventually replace VCR's in video-on-demand systems. The
timing and speed of this transition is dependent on availability of lower cost
servers.

         Most of the systems with video-on-demand service are in larger hotels,
where the economics of high channel capacity systems are more easily justified.
The conversion of hotel pay-per-view systems into video-on- demand is
increasing. Smaller hotels and motels have had limited video-on-demand
penetration to date, principally because of the headend cost associated with
each system and the limited revenues generated by the smaller number of rooms.

         International

         For much of the world, television service is in its infancy, but is
expected to rapidly expand as technological advancement reduces the cost to
consumers. In addition, economic development in Latin America and Asia has
allowed first time construction of integrated delivery systems which utilize a
variety of electronics and broadband hardware. The pace of growth is difficult
to predict, but as more alternatives become available and television service
becomes increasingly affordable, it is likely that more equipment will be placed
in the field.

         In October, 1997, the Company executed a two-year distribution
agreement with American Technology Exporters, Inc. ("Amtech"), a privately held
company based in Miami, Florida. Under the terms of the contract, Amtech is
required to purchase at least $3,000,000 per year of the Company's products and
has been granted distribution rights in the Caribbean, Mexico and Central and
South America. Amtech will also provide repair services for the Company's
products in certain of these areas. It is anticipated that this agreement will
increase the Company's international market penetration.

         Additional Considerations

         The technological revolution taking place in the communications
industry, which includes direct broadcast satellite, is providing digital
television to an increasing number of homes. Wireless cable systems also utilize
digital compression to provide channel capacity which is competitive with CATV
and other television delivery systems. In addition, franchised cable companies
and telephone companies, as stated earlier, are

                                       -5-

<PAGE>

building fiber optic networks to offer video data and telephony. There is also
the possibility of convergence of data and video communications, wherein
computer and television systems merge and the computer monitor replaces the
television screen. While it is not possible to predict with certainty which
technology will be dominant in the future, it is clear that digitized video and
advances in the ability to compress the digitized video signal make both digital
television and the convergence of computer, telephone and television systems
technically possible.

         Since United States television sets are analog (not digital), direct
satellite television and other digitally compressed programming requires Headend
Products or expensive set-top decoding receivers to convert the digitally
transmitted satellite signals back to analog. The replacement of all television
sets with digital sets will be costly and take many years to evolve. The Company
believes that for many years to come, program providers will be required to
deliver an analog television signal on standard channels to subscribers'
television sets using Headend Products at some distribution point in their
networks or employ decoding receivers at each television set. Headend Products
are the heart of Blonder Tongue's business and except for systems deploying
digital decoders at each television set (which is very expensive), the Company
believes VideoMask(TM) is an ideal product for a system operator to use to
control access to the multitude of programming that will be available. In the
completely digital environment which may develop over the long term, all analog
Headend Products will need to be replaced with pure digital products. The
Company and all other suppliers to Private Cable, CATV and the television
industry generally will need to design and manufacture new products for that
environment.

Products

         Blonder Tongue's products can be separated, according to function, into
the four broad categories described below:

         o Headend Products used by a system operator for signal acquisition,
         processing and manipulation for further transmission. Among the
         products offered by the Company in this category are satellite
         receivers (digital and analog), integrated receiver/decoders,
         demodulators, modulators, antennas and antenna mounts, amplifiers,
         equalizers, and processors. The headend of a television signal
         distribution system is the "brain" of the system, the central location
         where the multi-channel signal is initially received, converted and
         allocated to specific channels for distribution. In some cases, where
         the signal is transmitted in encrypted form or digitized and
         compressed, the receiver will also be required to decode the signal.
         Blonder Tongue is a licensee of General Instrument Corporation's
         VideoCipher(R) and DigiCipher(R) encryption technologies, EchoStar
         Communication Corp.'s digital technologies and Hughes Network Systems
         digital technologies and integrates their decoders into integrated
         receiver/decoder products, where required. The Company is negotiating
         with additional companies which are delivering digital television
         signal transmission to acquire licenses to incorporate their
         proprietary digital decoders into the Company's receivers. The Company
         estimates that Headend Products accounted for approximately 80% of the
         Company's revenues in 1997, 84% in 1996 and 90% in 1995.

         o Distribution Products used to permit signals to travel from the
         headend to their ultimate destination in a home, apartment unit, hotel
         room, office or other terminal location along a distribution network of
         fiber optic or coaxial cable. Among the products offered by the Company
         in this category are line extenders, broadband amplifiers, directional
         taps, splitters and wall taps. In CATV systems, the distribution
         products are either mounted on exterior telephone poles or encased in
         pedestals, vaults or other security devices. In Private Cable systems
         the distribution system is typically enclosed within the walls of the
         building (if a single structure) or added to an existing structure
         using various techniques to hide the coaxial cable and devices. The
         non-passive devices within this category are designed to ensure that
         the signal distributed from the headend is of sufficient strength when
         it arrives at its final destination to provide high quality audio/video
         images.

                                       -6-

<PAGE>

         o Subscriber Products used to control access to programming at the
         subscriber's location and to split and amplify incoming signals for
         transmission to multiple sites and multiple television sets within a
         site. Among the products offered by the Company in this category are
         addressable interdiction devices, splitters, couplers and multiplexers.
         The Company believes that the most significant products within this
         category are (i) its new VideoMask(TM) addressable signal jammer,
         licensed from Philips Electronics North America Corporation and its
         affiliate Philips Broadband Networks, Inc. in August 1995 under certain
         non-exclusive technology and patent license agreements (the "Philips
         License Agreements"), and (ii) the interdiction product line acquired
         from Scientific as part of its Interdiction Business. Interdiction
         products such as these limit, through jamming of particular channels,
         the availability of programs to subscribers. Such products enable an
         integrator to control subscriber access to premium channels and other
         enhanced services through a computer located off-premises. They also
         eliminate the necessity of an operator having to make a service call to
         install or remove passive traps and eliminate the costs associated
         with damage or loss of set-top converters in the subscribers'
         locations. While it is not possible to predict the breadth of market
         acceptance for these products, the Company believes the potential is
         substantial in both the MDU market as well as in the CATV market as
         alternatives to set-top converters and as a viable option for telephone
         companies, electric utilities and other new entrants to television
         signal distribution, who are planning to over-build existing cable
         infrastructures and are seeking a cost effective way to compete with
         CATV.

         o Microwave Products used to transmit the output of a cable system
         headend to multiple locations using point-to-point communication links
         in the 13 GHz (for CATV) and 18 GHz (for Private Cable) range of
         frequencies. Among the products offered by the Company in this category
         are power amplifiers, repeaters, receivers, transmitters and compatible
         accessories. These products convert the headend output up to the
         microwave band and transmit this signal using parabolic antennas. At
         each receiver site, a parabolic antenna-receiver combination converts
         the signal back to normal VHF frequencies for distribution to
         subscribers at the receiver site. The Company believes that this class
         of products will be a major catalyst for growth in the Private Cable
         MDU market and will be a strategic element in developing the Company's
         CATV market penetration.

         The Company will modify its products to meet specific customer
requirements. Typically, these modifications are minor and do not materially
alter the functionality of the products. Thus the inability of the customer to
accept such products does not generally result in the Company being otherwise
unable to sell such products to other customers.

Research and Product Development

         The markets served by Blonder Tongue are characterized by technological
change, new product introductions, and evolving industry standards. To compete
effectively in this environment, the Company must engage in continuous research
and development in order to (i) create new products, (ii) expand the frequency
range of existing products in order to accommodate customer demand for greater
channel capacity, (iii) license new technology (such as digital satellite
receiver decoders), and (iv) acquire products incorporating technology which
could not otherwise be developed quickly enough using internal resources, to
suit the dynamics of the evolving marketplace. Research and development projects
are often initially undertaken at the request of and in an effort to address the
particular needs of its customers and customer prospects with the expectation or
promise of substantial future orders from such customers or customer prospects.
Additional research and development efforts are also continuously underway for
the purpose of enhancing product quality and engineering to lower production
costs. For the acquisition of new technologies, the Company may rely upon
technology licenses from third parties when the Company believes that it can
obtain such technology more quickly and/or cost-effectively from such third
parties than the Company could otherwise develop on its own, or when the desired
technology is proprietary to a third party. There were 21 employees in the
research and development department of the Company at December 31, 1997.

                                       -7-

Marketing and Sales

         Blonder Tongue markets and sells its products worldwide to Private
Cable integrators, which accounted for approximately 80% of the Company's
revenues for fiscal years 1997, 1996 and 1995, to regional and long distance
telephone service providers, and to CATV integrators. Sales are made directly to
customers by the Company's internal sales force, as well as through numerous
domestic and international stocking distributors.

         The Company historically maintained contractual relationships with
numerous independent sales representatives. In February, 1998, the Company
terminated its contractual relationships with its independent sales
representatives because management believes its internal sales force has the
capacity to maintain or increase sales formerly made through independent sales
representatives without the necessity of paying sales commissions. Should it be
deemed necessary, the Company may retain independent sales representatives in
particular geographic areas or targeted to specific customer prospects.

         The Company's internal sales force consists of approximately 21
employees, which currently includes five salespersons (one salesperson in each
of Old Bridge, New Jersey, Cincinnati, Ohio, Plano, Texas, Covina, California
and Moreno Valley, California) and 16 sales-support personnel at the Company
headquarters in Old Bridge, New Jersey.

         The Company's standard customer payment terms are 2%-10, net 30 days.
From time to time where the Company determines that circumstances warrant, such
as when a customer agrees to commit to a large blanket purchase order, the
Company extends payment terms beyond its standard payment terms.

         The Company has several marketing programs to support the sale and
distribution of its products. Blonder Tongue participates in industry trade
shows and conferences. The Company also publishes technical articles in trade
and technical journals, distributes sales and product literature and has an
active public relations plan to ensure complete coverage of Blonder Tongue's
products and technology by editors of trade journals. The Company provides
system design engineering for its customers, maintains extensive ongoing
communications with many original equipment manufacturer customers and provides
one-on-one demonstrations and technical seminars to potential new customers.
Blonder Tongue supplies sales and applications support, product literature and
training to its sales representatives and distributors. The management of the
Company travels extensively, identifying customer needs and meeting potential
customers.

         The Company had approximately $5,375,000 and $3,248,000 in purchase
orders as of December 31, 1997 and December 31, 1996, respectively. All of the
purchase orders outstanding as of December 31, 1997 are expected to be shipped
prior to December 31, 1998. The purchase orders are for the future delivery of
products and are subject to cancellation by the customer.

Customers

         Blonder Tongue has a broad customer base, which in 1997 consisted of
more than 1,000 active accounts. Approximately 40%, 39% and 46% of the Company's
revenues in fiscal years 1997, 1996 and 1995, respectively, were derived from
sales of products to the Company's five largest customers. In 1997, sales to
OpTel, Inc. accounted for approximately 16% of the Company's revenues. Sales to
the five largest customers consisted principally of Headend Products. There can
be no assurance that any sales to these entities, individually or as a group,
will reach or exceed historical levels in any future period. However, the
Company anticipates that these customers will continue to account for a
significant portion of the Company's revenues in future periods, although none
of them is obligated to purchase any specified amount of products (beyond
outstanding purchase orders) or to provide the Company with binding forecasts of
product purchases for any future period.


                                       -8-

         The complement of leading customers may shift as the most efficient and
better financed integrators grow more rapidly than others. The Company believes
that many integrators will grow rapidly, and as such the Company's success will
depend in part on the viability of those customers and on the Company's ability
to maintain its position in the overall marketplace by shifting its emphasis to
those customers with the greatest growth and growth prospects. Any substantial
decrease or delay in sales to one or more of the Company's leading customers,
the financial failure of any of these entities, or the Company's inability to
develop and maintain solid relationships with the integrators which may replace
the present leading customers, would have a material adverse effect on the
Company's results of operations and financial condition.

         The Company's revenues are derived primarily from customers in the
continental United States, however, the Company also derives revenues from
customers outside the continental United States, primarily in underdeveloped
countries. Television service is in its infancy in many international markets,
particularly Latin America and Asia, creating opportunity for those participants
who offer quality products at a competitive price. Sales to customers outside of
the United States represented approximately 3%, 5% and 9% of the Company's
revenues in fiscal years 1997, 1996 and 1995, respectively. All of the Company's
transactions with customers located outside of the continental United States are
denominated in U.S. dollars, therefore, the Company has no material foreign
currency transactions.

Manufacturing and Suppliers

         Blonder Tongue's manufacturing operations are located at the Company's
headquarters in Old Bridge, New Jersey. The Company's manufacturing operations
are vertically integrated and consist principally of the assembly and testing of
electronic assemblies built from fabricated parts, printed circuit boards and
electronic devices and the fabrication from raw sheet metal of chassis and
cabinets for such assemblies. Management continues to implement a significant
number of changes to the manufacturing process to increase production volume and
reduce product cost, including logistics modifications on the factory floor, an
increased use of surface mount, axial lead and radial lead robotics to place
electronic components on printed circuit boards, a continuing program of circuit
board redesign to make more products compatible with robotic insertion equipment
and an increased integration in machining and fabrication. All of these efforts
are consistent with and part of the Company's strategy to provide its customers
with high performance-to-cost ratio products.

         Outside contractors supply standard components and etch printed circuit
boards to the Company's specifications. While the Company generally purchases
electronic parts which do not have a unique source, certain electronic component
parts used within the Company's products are available from a limited number of
suppliers and can be subject to temporary shortages because of general economic
conditions and the demand and supply for such component parts. If the Company
were to experience a temporary shortage of any given electronic part, the
Company believes that alternative parts could be obtained or system design
changes implemented. However, in such situations the Company may experience
temporary reductions in its ability to ship products affected by the component
shortage. The Company purchases several products from sole suppliers for which
alternative sources are not available, such as the VideoCipher(R) and
DigiCipher(R) encryption systems manufactured by General Instrument Corporation,
which are standard encryption methodology employed on U.S. C-Band and Ku-Band
transponders, EchoStar digital satellite receiver decoders, which are
specifically designed to work with the DISH Network(TM), and Hughes Network
Systems digital satellite receivers for delivery of DIRECTV(R) programming. An
inability to timely obtain sufficient quantities of these components could have
a material adverse effect on the Company's operating results. The Company does
not have a supply agreement with General Instrument Corporation or any other
supplier. The Company submits purchase orders to its suppliers on an as-needed
basis.

         Blonder Tongue maintains a quality assurance program which tests
samples of component parts purchased, as well as its finished products, on an
ongoing basis and also conducts tests throughout the manufacturing process using
commercially available and in-house built testing systems that incorporate

                                       -9-

<PAGE>

proprietary procedures. Blonder Tongue performs final product tests on 100% of
its products prior to shipment to customers.

Competition

         All aspects of the Company's business are highly competitive. The
Company competes with national, regional and local manufacturers and
distributors, including companies larger than Blonder Tongue which have
substantially greater resources. Various manufacturers who are suppliers to the
Company sell directly as well as through distributors into the CATV and Private
Cable marketplaces. Because of the convergence of the cable, telecommunications
and computer industries and rapid technological development, new competitors may
seek to enter the principal markets served by the Company. Many of these
potential competitors have significantly greater financial, technical,
manufacturing, marketing, sales and other resources than Blonder Tongue. The
Company expects that direct and indirect competition will increase in the
future. Additional competition could result in price reductions, loss of market
share and delays in the timing of customer orders. The principal methods of
competition are product differentiation, performance and quality, price and
terms, service, and technical and administrative support.

Intellectual Property

         Excluding the patents obtained from Scientific in connection with the
acquisition of their Interdiction Business, the Company currently holds 11
United States patents and 4 foreign patents covering a wide range of electronic
systems and circuits. None of these patents, however, are considered material to
the Company's present operations because they do not relate to high volume
applications. Because of the rapidly evolving nature of the Private Cable and
CATV industries, the Company believes that its market position as a leading
supplier to Private Cable derives primarily from its ability to develop a
continuous stream of new products which are designed to meet its customers'
needs and which have a high performance-to-cost ratio.

         The Company is a licensee of Philips Electronics North America
Corporation and its affiliate Philips Broadband Networks, Inc., General
Instrument Corporation ("GI"), Houston Tracker Systems, Inc., a subsidiary of
EchoStar Communications Corp. ("EchoStar"), Hughes Network Systems, a Hughes
Electronics Corporation ("Hughes") and several smaller software development
companies.

         Under the Philips License Agreements, the Company is granted a
non-exclusive license for a term which expires in 2010, concurrently with the
last to expire of the relevant patents. The Philips License Agreements provide
for the payment by the Company of a one-time license fee and for the payment by
the Company of royalties based upon unit sales of licensed products.

         The Company is a licensee of GI relating to GI's VideoCipher(R)
encryption technology and is also a party to a private label agreement with GI
relating to its DigiCipher(R) technology. Under the VideoCipher(R) license
agreement, the Company is granted a non-exclusive license under certain
proprietary know-how, to design and manufacture certain licensed products to be
compatible with the VideoCipher(R) commercial descrambler module for a term of
ten years, expiring in August, 2000. The VideoCipher(R) license agreement
provides for the payment by the Company of a one-time license fee for the
Company's first model of licensed product and additional one-time license fees
for each additional model of licensed product. The VideoCipher(R) license
agreement also provides for the payment by the Company of royalties based upon
unit sales of licensed products. Under the DigiCipher(R) private label
agreement, the Company is granted the non-exclusive right to sell DigiCipher(R)
II integrated receiver decoders bearing the Blonder Tongue name for use in the
commercial market for a term expiring in December, 1998. The DigiCipher(R)
private label agreement provides for the payment by the Company of a one-time
license fee for the Company's first model of licensed product and additional
one-time license fees for each additional model of licensed product.

         In November, 1996, the Company entered into a license agreement with
EchoStar, pursuant to which the Company is licensed to manufacture and sell
digital satellite receiver systems which are compatible with digital programming
transmitted by EchoStar's DISH Network(TM), for use in the commercial market.
The agreement is for a term of five years, expiring in November, 2001. The
EchoStar license agreement provides for the payment by the Company of a one-time
license fee and for the payment of royalties based upon unit sales of licensed
products.

         During 1996, the Company also entered into several software development
and license agreements for specifically designed controller and interface
software necessary for the operation of the Company's Video Central(TM) remote
interdiction control system, which is used for remote operation of VideoMask(TM)
signal jammers installed at subscriber locations. These licenses are perpetual
and require the payment of a one-time license fee and in one case additional
payments, the aggregate of which are not material.

         In February, 1998, the Company entered into an exclusive license
agreement with Hughes, pursuant to which the Company is licensed to design,
manufacture, and market commercial digital satellite receivers which are
compatible with DIRECTV(R) programming, for use in headend applications in both
the franchised and private cable markets. The agreement is for a term of five
(5) years, expiring in February 2003.

         In connection with the acquisition of Scientific's Interdiction
Business in March, 1998, the Company acquired all intellectual property and
related technology associated with the Interdiction Business, including 29
patents filed in the United States and/or abroad.

         The Company relies on a combination of contractual rights and trade
secret laws to protect its proprietary technology and know-how. There can be no
assurance that the Company will be able to protect its technology and know-how
or that third parties will not be able to develop similar technology and
know-how independently. Therefore, existing and potential competitors may be
able to develop products that are competitive with the Company's products and
such competition could adversely affect the prices for the Company's products or
the Company's market share. The Company also believes that factors such as the
technological and creative skills of its personnel, new product developments,
frequent product enhancements, name recognition and reliable product maintenance
are essential to establishing and maintaining its leadership position.

Regulation

         Private Cable (estimated by the Company to represent approximately 80%
of its business), while in some cases subject to certain FCC licensing
requirements, is not presently burdened with extensive government regulations.
CATV operators (estimated by the Company to represent approximately 20% of its
business) had been subject to extensive government regulation pursuant to the
Cable Television Consumer Protection and Competition Act of 1992, which among
other things provided for rate rollbacks for basic tier cable service, further
rate reductions under certain circumstances and limitations on future rate
increases. The Telecommunications Act of 1996 has deregulated many aspects of
CATV system operation and has opened the door to competition among cable
operators and telephone companies in each of their respective industries. The
Company believes that this legislation will increase the base of potential
customers for the Company's products.

Environmental Regulations

         The Company is subject to a variety of federal, state and local
governmental regulations related to the storage, use, discharge and disposal of
toxic, volatile or otherwise hazardous chemicals used in its manufacturing
processes. The Company did not incur in 1997 and does not anticipate incurring
in 1998 material capital expenditures for compliance with federal, state and
local environmental laws and regulations. There can be no assurance, however,
that changes in environmental regulations will not result in the need for
additional capital expenditures or otherwise impose additional financial burdens
on the Company. Further, such

                                      -11-

<PAGE>

regulations could restrict the Company's ability to expand its operations. Any
failure by the Company to obtain required permits for, control the use of, or
adequately restrict the discharge of, hazardous substances under present or
future regulations could subject the Company to substantial liability or could
cause its manufacturing operations to be suspended.

         The Company presently holds a permit from the New Jersey Department of
Environmental Protection ("NJDEP"), Division of Environmental Quality, Air
Pollution Control Program relating to its operation of certain process
equipment, which permit expires in June, 2001. The Company has held such a
permit for this equipment on a substantially continuous basis since
approximately April, 1989. The Company also has authorization under the New
Jersey Pollution Discharge Elimination System/Discharge to Surface Waters
General Industrial Stormwater Permit, Permit No. NJ0088315. This permit will
expire November 1, 1998. The Company anticipates that such permit will
be renewed.

Employees

         The Company employs approximately 587 persons, including 458 in
manufacturing, 21 in research and development, 20 in quality assurance, 45 in
production services, 21 in sales and marketing, and 22 in a general and
administrative capacity. 396 of the Company's employees are members of the
International Brotherhood of Electrical Workers Union, Local 2066, which has a
three year labor agreement with the Company expiring in February, 1999.

ITEM 2. PROPERTIES

         The Company's principal manufacturing, engineering, sales and
administrative facilities consist of one building totalling approximately
130,000 square feet located on approximately 20 acres of land in Old Bridge, New
Jersey (the "Old Bridge Facility") which is owned by the Company. Until June 30,
1997, the Company leased approximately 8,100 square feet of space in San Diego,
California for which it paid base rent of approximately $4,100 per month, which
base rent was offset by sublease income associated with such space of
approximately $2,000 per month. The Company also leases office space in
Cincinnati, Ohio and Grapevine, Texas for which it pays rent of approximately
$260 and $1,000 per month, respectively.

         Management believes that the Old Bridge Facility is adequate to support
the Company's anticipated needs in 1998. Subject to compliance with applicable
zoning and building codes, the Old Bridge real property is large enough to
double the size of the plant to accommodate expansion of the Company's
operations should the need arise.

ITEM 3. LEGAL PROCEEDINGS

         On October 18, 1996, the Company was served with a complaint in a
lawsuit filed by Scientific- Atlanta, Inc. ("Scientific") in the United States
District Court for the Northern District of Georgia alleging patent infringement
by the Company's VideoMask(TM) interdiction product. The complaint requested an
unspecified amount of damages and injunctive relief.

         Following the Company's acquisition of the assets and technology rights
of Scientific's Interdiction Business, Scientific's lawsuit against the Company
was dismissed with prejudice.

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

         No matters were submitted to a vote of security holders during the
fourth quarter ended December 31, 1997 through the solicitation of proxies or
otherwise.

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

         The Company's common stock has been traded on the American Stock
Exchange since the Company's initial public offering on December 14, 1995. The
following table sets forth for the fiscal quarters indicated, the high and low
sale prices for the Company's Common Stock on the American Stock Exchange.

         The Company's Common Stock is traded on the American Stock Exchange
under the symbol "BDR".

Holders

         As of March 16, 1998, the Company had approximately 76 holders of
record of the Common Stock. Since a portion of the Company's common stock is
held in "street" or nominee name, the Company is unable to determine the exact
number of beneficial holders.

Dividends

         The Company currently anticipates that it will retain all of its
earnings to finance the operation and expansion of its business, and therefore
does not intend to pay dividends on its Common Stock in the foreseeable future.
Other than in connection with certain S Corporation distributions, the Company
has never declared or paid any cash dividends on its Common Stock. Any
determination to pay dividends in the future is at the discretion of the
Company's Board of Directors and will depend upon the Company's financial
condition, results of operations, capital requirements, limitations contained in
loan agreements and such other factors as the Board of Directors deems relevant.
The Company's loan agreement with CoreStates Bank prohibits the payment of
dividends by the Company on its Common Stock, unless at the time of and after
giving effect to any proposed dividend payment, the Company is not in default
under the loan agreement and is in compliance with certain financial covenants
relating to, among other things, working capital, tangible net worth and debt
service coverage.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

         The following discussion and analysis of the Company's historical
results of operations and liquidity and capital resources should be read in
conjunction with "Selected Consolidated Financial Data" and the consolidated
financial statements of the Company and notes thereto appearing elsewhere
herein.

Overview

         The Company was incorporated in November, 1988, under the laws of
Delaware as GPS Acquisition Corp. for the purpose of acquiring the business of
Blonder-Tongue Laboratories, Inc., a New Jersey corporation which was founded in
1950 by Ben H. Tongue and Isaac S. Blonder (the "former Blonder-Tongue") to
design, manufacture and supply a line of electronics and systems equipment
principally for the Private Cable industry. Following the acquisition, the
Company changed its name to Blonder Tongue Laboratories, Inc.

         The Company's success is due in part to management's efforts to
leverage the Company's reputation by broadening its product line to offer
one-stop shop convenience to Private Cable and CATV system integrators and to
deliver products having a high performance-to-cost ratio. The Company has
experienced significant growth since the acquisition of the former
Blonder-Tongue, both internally and through strategic acquisitions.

         In December 1995, the Company successfully concluded an initial public
offering of 2,200,000 shares of its Common Stock. Thereafter, in January 1996,
the Company's underwriters exercised their over-allotment option, as a result of
which an additional 181,735 shares of the Company's Common Stock were sold. The
proceeds received by the Company from the sale of its Common Stock in the
offering (including shares sold pursuant to the over-allotment option), net of
expenses of the offering and certain S Corporation distributions to the
Company's principal stockholders, was approximately $14,045,000. These funds
were used to acquire the Company's Old Bridge Facility and to reduce the
Company's outstanding bank debt. The Company has further enhanced its liquidity
through a long-term loan secured by a mortgage against the Old Bridge Facility.

         On March 26, 1998, the Company acquired all of the assets and
technology rights of the interdiction business (the "Interdiction Business") of
Scientific-Atlanta, Inc. ("Scientific") for a purchase price consisting of (i)
$19 million in cash, (ii) 67,889 shares of the Company's common stock, (iii) a
warrant to purchase 150,000 additional shares of the Company's common stock at
an exercise price of $14.25 per share and (iv) assumption by the Company of
certain obligations under executory contracts with vendors and customers and
certain warranty obligations and other current liabilities of the Interdiction
Business. The Interdiction Business generated approximately $16 million in
revenues for the prior twelve month period. The Company believes that
Scientific's interdiction products, which have been engineered primarily to
serve the franchised cable market, will supplement the Company's VideoMask(TM)
products, which are primarily focused on the Private Cable market. In addition,
the Company expects that the technology acquired as part of the Interdiction
Business will enhance its ability to design products that meet the specific
needs of all cable providers, while improving its position in the franchised
cable market.

Results of Operations

         The following table sets forth, for the fiscal periods indicated,
certain consolidated statement of earnings data as a percentage of net sales:

1997 Compared with 1996

         Net Sales. Net sales increased $13,195,000, or 27%, to $62,057,000 in
1997 from $48,862,000 in 1996. International sales accounted for $1,620,000
(2.6% of total sales) for 1997 compared to $2,655,000 (5.4% of total sales) for
1996. Net sales did not include any milestone billings under the Company's
agreement with Pacific Bell for 1997 compared to $2,192,000 for 1996.

         The increase in sales is primarily attributed to an increase in demand
for products in the MDU market and the continued growth in the Lodging market.
In addition, the sales of VideoMask(TM) interdiction equipment remained strong.
Net sales included approximately $7,567,000 of VideoMask(TM) interdiction
equipment for 1997 compared to $2,939,000 for 1996.

         Effective July 18, 1997, the Company's agreement to supply interdiction
equipment to Pacific Bell was terminated. The termination did not have a
significant impact on 1997 sales. The Pacific Bell contract contained provisions
for penalties upon early termination by either party. In July, 1997, the Company
received a payment in the amount of $1.5 million from Pacific Bell for
reimbursement of costs incurred by the Company through the date of termination.
The payment was offset by a portion of the costs incurred by the Company for
customized inventory ($708,000) and operating expenses ($257,000) incurred in
connection with the contract.In addition, the Company recognized $535,000 in 
other income.

         Cost of Goods Sold. Cost of goods sold increased to $39,656,000 for
1997 from $30,613,000 for 1996, primarily due to increased volume, and increased
as a percentage of sales to 63.9% from 62.7%. The increase as a percentage of
sales was caused primarily by a greater proportion of sales during the period
being comprised of lower margin products.

         Selling Expenses. Selling expenses increased to $4,964,000 in 1997 from
$4,780,000 in 1996, but decreased as a percentage of sales to 8.0% in 1997 from
9.8% in 1996. The dollar increase was primarily due to an increase in
commissions ($128,000) as a result of the increase in sales, an increase in
shipping materials ($86,000) and an increase in royalty payments related to
licensing agreements ($76,000). These increases were offset by a reduction of
costs incurred for trade shows ($142,000).

         General and Administrative Expenses. General and administrative
expenses increased to $4,974,000 in 1997 from $4,355,000 for 1996 but decreased
as a percentage of sales to 8.0% in 1997 from 8.9% for 1996.

                                      -16-

<PAGE>

The $619,000 increase can be primarily attributable to an increase in the
accrual for executive bonuses in connection with the implementation of the
Company's Executive Officer Salary Bonus Plan and an increase in the allowance
for doubtful accounts related to the increase in sales volume.

         Research and Development Expenses. Research and development expenses
decreased 1% to $1,954,000 in 1997 from $1,972,000 in 1996, primarily due to the
reimbursement of costs incurred as a result of the termination of the Pacific
Bell contract and a decrease in expenditures for consulting services that were
incurred with respect to the VideoMask(TM) product line in 1996. These decreases
were offset by an increase in amortization of technology license agreements, an
increase in depreciation expense related to the acquisition of new equipment and
an increase in wages due to the hiring of personnel with higher qualifications.
Research and development expenses also decreased as a percentage of sales to
3.2% from 4.0%.

         Operating Income. Operating income increased 47.1% to $10,509,000 for
1997 from $7,142,000 for 1996. Operating income as a percentage of sales
increased to 16.9% in 1997 from 14.6% in 1996.

         Interest and Other Expenses. Other income in 1997 consisted of $535,000
related to the final payment received from Pacific Bell as a result of the
contract termination in July, 1997, along with $60,000 of interest income offset
by $414,000 of interest expense. Other expenses in 1996 consisted of interest
expense of $658,000. The reduction in interest expense is primarily attributed
to reduced borrowings under the Company's credit line.

         Income Taxes. The provision for income taxes for 1997 increased to
$4,276,000 from $2,601,000 for 1996 as a result of increased taxable income. The
effective tax rate for both years remained at 40%.

1996 Compared with 1995

         Net Sales. Net sales decreased $3,120,000, or 6.0%, to $48,862,000 in
1996 from $51,982,000 in 1995. International sales accounted for $2,655,000
(5.4% of total sales) for 1996 compared to $4,809,000 (9.3% of total sales) for
1995. Net sales included approximately $2,939,000 of VideoMask(TM) interdiction
equipment. Net sales also included $2,192,000 under the Company's agreement to
supply interdiction equipment to Pacific Bell.

         Sales in the lodging market remained strong during 1996 but MDU sales
were impacted by the uncertainty surrounding the installation of private cable
systems in properties under contract to Interactive Cable Systems, Inc. ("ICS"),
one of the Company's largest customers in 1995. Net sales to ICS were
approximately $684,000 in 1996 compared to approximately $9,266,000 in 1995.
Approximately $655,000 of accounts receivable outstanding at December 31, 1996
was due from ICS for more than 60 days, compared with approximately $933,000
outstanding for more than 60 days at December 31, 1995.

         Longer than anticipated accelerated life testing of the Company's, new
VideoMask(TM) interdiction product delayed production until early March, 1996.
Thereafter, volume interdiction sales were further delayed due to the inability
of ICS to complete the installation of private cable systems in properties under
contract to them and the shift in demand to other users of interdiction whose
requirements were for product configurations not yet in production.

         Cost of Goods Sold. Cost of goods sold decreased to $30,613,000 in 1996
from $32,528,000 in 1995 but increased as a percentage of sales to 62.7% from
62.6%. The increase as a percentage of sales was caused primarily by a greater
proportion of sales during the period being comprised of lower margin products.
Reconfiguration costs and low volume production of VideoMask(TM) during 1996
affected gross margins of the product. As VideoMask(TM) volume increases,
margins on such products should improve, although there can be no assurance that
additional delays will not occur or that volume will increase.

                                      -17-

<PAGE>

         Selling Expenses. Selling expenses decreased to $4,780,000 in 1996 from
$4,824,000 in 1995, primarily due to decreased costs incurred for commissions as
a result of the termination of certain sales representatives offset by increased
expenditures for marketing materials, royalties related to certain license
agreements and increased operational costs of the BTI sales office along with
additional costs incurred in connection with the closure of such office.

         General and Administrative Expenses. General and administrative
expenses decreased to $4,355,000 in 1996 from $4,967,000 for 1995 and also
decreased as a percentage of sales to 8.9% in 1996 from 9.5% in 1995. The
$612,000 decrease can be attributed to a reduction in rent expense, net of
increased depreciation, as a result of the Company's purchase of the Old Bridge
Facility and a decline in salaries due to a reduction in personnel, offset by an
increase in expenditures for professional services and insurance.

         Research and Development Expenses. Research and development expenses
decreased 1.9% to $1,972,000 in 1996 from $2,011,000 in 1995, primarily due to a
decrease in consulting services incurred, which were primarily attributable to
the development of the VideoMask(TM) interdiction product line during 1995 and
the first half of 1996, offset by an increase in purchased materials for
research and development. Research and development expenses increased as a
percentage of sales to 4.0% from 3.9%.

         Operating Income. Operating income decreased 6.7% to $7,142,000 in 1996
from $7,652,000 in 1995. Operating income as a percentage of sales decreased to
14.6% in 1996 from 14.7% in 1995.

         Interest and Other Expenses. Other expenses, net, decreased to $658,000
in 1996 from $1,236,000 in 1995. These expenses in 1996 consisted of interest
expense in the amount of $658,000. Other expenses in 1995 consisted of interest
expense of $1,296,000, offset by $60,000 of other income. The reduction in
interest expense is primarily attributed to reduced borrowings under the
Company's credit line.

         Income Taxes. The Company, with the consent of its stockholders,
elected to be taxed as an S Corporation for federal income tax purposes from its
inception until its initial public offering of common stock. As a consequence,
the taxable net earnings of the Company were taxed as income to the Company's
stockholders in proportion to their individual stockholdings, and the payment of
federal income taxes on such proportionate share of the Company's taxable
earnings was the personal obligation of each stockholder. The Company's status
as an S Corporation terminated on December 11, 1995, and as a result the Company
is now a C Corporation for income tax purposes. As a C Corporation, the Company
is currently taxed at a combined effective rate of approximately 40% based upon
current federal and state income tax regulations. Had the Company been taxable
as a C Corporation for the entire year of 1995, pro forma income taxes and pro
forma net earnings after taxes for the year ended December 31, 1995 would have
been $2,566,000 and $3,850,000, respectively, compared with a provision for
income taxes and net earnings after taxes for the year ended December 31, 1996
of $2,601,000 and $3,883,000, respectively.

Inflation and Seasonality

         Inflation and seasonality have not had a material impact on the results
of operations of the Company. Fourth quarter sales in 1997 were slightly
impacted by fewer production days. The Company expects sales each year in the
fourth quarter to be impacted by fewer production days.

Year 2000

         Historically, computer programs have been written using two digits
rather than four to define the applicable year. Such programs were written
without considering the impact of the upcoming change in the century and may
experience problems handling dates beyond December 31, 1999. This could cause
computer applications to fail or to create erroneous results unless corrective
measures are taken. Incomplete or untimely

                                      -18-

<PAGE>

resolution of the Year 2000 issue could have a material adverse impact on the
Company's business, operations or financial condition in the future.

         The Company has been assessing the impact that the Year 2000 issue will
have on its computer systems, including both hardware and software utilized by
the Company, since 1994. In response to these assessments, which are ongoing,
the Company has developed and is implementing a plan to develop solutions to
those systems found to have date-related deficiencies. Project plans call for
the completion of the solution implementation phase and testing of such
solutions prior to any anticipated impact on the Company's systems. The Company
is also surveying its bank and critical suppliers and customers to determine the
status of their Year 2000 compliance programs.

        Based on the current status of the Company's Year 2000 compliance
program, and assuming that project plans, which continue to evolve, can be
implemented as planned, the Company believes future costs relating to the Year
2000 issue will not have a material adverse impact on the Company's business,
operations or financial condition.

Liquidity and Capital Resources

       As of December 31, 1997 and 1996, the Company's working capital was
$26,055,000 and $23,015,000, respectively. The increase in working capital is
attributable primarily to the Company's net earnings offset by a $1,278,000
reclassification of certain promissory notes to shareholders as a current
liability due to their maturity dates being within one year and capital
expenditures of $1,424,000. Historically, the Company has satisfied its cash
requirements primarily from net cash provided by operating activities and from
borrowings under its line of credit.

     The Company's net cash provided by operating activities for the period
ended December 31, 1997 was $2,290,000 as a result of the Company's net earnings
offset by $1,847,000 to fund the increase in inventory and $4,470,000 related to
the increase in accounts receivable, compared to cash used in operating
activities for the period ended December 31, 1996 of $534,000. 

         Cash used in investing activities was $1,587,000. $163,000 was utilized
for fees associated with the acquisition of certain license agreements, and
$1,424,000 is attributable to capital expenditures for new equipment. The
Company purchased several high speed robotic insertion machines which are used
primarily in the manufacture of circuit boards for the Company's new
VideoMask(TM) product line and the balance was used for the purchase of other
automated assembly and test equipment. The Company does not have any present
plans or commitments for material capital expenditures for fiscal year 1998,
other than in connection with the acquisition of Scientific's Interdiction
Business.

         Cash used in financing activities was $1,488,000 for the period ended
December 31, 1997, comprised primarily of $1,176,000 of payments on the
Company's line of credit, prepayments of $313,000 on notes to shareholders and
repurchase of $498,000 of the Company's common stock under the Company's stock
repurchase program, offset by $303,000 in proceeds relating to the exercise of
stock options.

         In October, 1997, the Company executed a new $15 million revolving line
of credit with its bank, on which funds may be borrowed at the bank's overnight
base rate ("OBR") plus a margin ranging from .95% to 2.45%, depending upon the
calculation of certain financial covenants (7.7% at December 31, 1997). As of
December 31, 1997, the Company had no balance outstanding under the line of
credit. The line of credit is collateralized by a security interest in all of
the Company's assets. The agreement contains restrictions that

                                      -19-

<PAGE>

require the Company to maintain certain financial ratios as well as restrictions
on the payment of dividends. In addition, the Company has an acquisition loan
commitment which may be drawn upon by the Company to finance acquisitions in
accordance with certain terms. The acquisition loan commitment had been $15
million until March, 1998 when it was increased to $20 million to accommodate
the acquisition of Scientific's Interdiction Business. Funds may be borrowed
under the acquisition loan commitment at OBR plus a margin ranging from 1.25% to
2.75%, depending upon the calculation of certain financial covenants. At
December 31, 1997, there was no balance outstanding under the acquisition loan
commitment and as of March 26, 1998, there was $19 million outstanding under the
acquisition loan commitment. The line of credit and the acquisition loan
commitment expire on June 30, 1999.

         On May 24, 1996, the Company borrowed $2.8 million for a ten year term
secured by a mortgage against the Old Bridge Facility. The loan bears interest
at the fixed rate of 7.25% through May 1999 and may be negotiated to another
fixed rate or remain variable for the remaining seven years of the loan.

         The Company currently anticipates that the cash generated from
operations, existing cash balances and amounts available under its existing or a
replacement line of credit, will be sufficient to satisfy its foreseeable
working capital needs.

New Accounting Pronouncements

         In June 1997, SFAS 130, "Reporting Comprehensive Income," and SFAS 131,
"Disclosures About Segments of an Enterprise and Related Information," were
issued. SFAS 130 addresses standards for reporting and display of comprehensive
income and its components and SFAS 131 requires disclosure of reportable
operating segments. In February 1998, SFAS 132, "Employer's Disclosures About
Pensions and Other Postretirement Plans" was issued. SFAS 132 standardizes
pension disclosures. These statements are effective in 1998. The Company will be
reviewing these pronouncements to determine their applicability to the Company,

Additional Factors That May Affect Future Results and Market Price of Stock

         Blonder Tongue's business operates in a rapidly changing environment
that involves a number of risks, some of which are beyond the Company's control.
The following discussion highlights some of these risks which are not otherwise
addressed elsewhere in this Annual Report. There can be no assurance that the
Company will anticipate the evolution of industry standards in Private Cable or
the communications industry generally, changes in the market and customer needs,
or that technologies and applications under development by the Company will be
successfully developed, or if they are successfully developed, that they will
achieve market acceptance. The competition to attract and retain highly-skilled
engineering, manufacturing, marketing and managerial personnel is intense.
Capital spending by cable operators for constructing, rebuilding, maintaining or
upgrading their systems (upon which the Company's sales and profitability are
dependent) is dependent on a variety of factors, including access to financing,
demand for their cable services, availability of alternative video delivery
technologies, and general economic conditions. Factors such as announcements of
technological innovations or new products by the Company, its competitors or
third parties, quarterly variations in the Company's actual or anticipated
results of operations, market conditions for emerging growth stocks or cable
industry stocks in general, or the failure of revenues or earnings in any
quarter to meet the investment community's expectations, may cause the market
price of the Company's Common Stock to fluctuate significantly. The stock price
may also be affected by broader market trends unrelated to the Company's
performance.

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. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Blonder
Tongue Laboratories, Inc. and subsidiaries as of December 31, 1997 and 1996, and
the results of their operations and their cash flows for each of the three years
in the period ended December 31, 1997 in conformity with generally accepted
accounting principles.

                    (In thousands, except per share amounts)



Note 1 - Summary of Significant Accounting Policies

(a) Company and Basis of Presentation

         Blonder Tongue Laboratories, Inc. (the "Company") is a manufacturer of
television and satellite signal distribution equipment supplied to the private
cable television and broadcast industries. The consolidated financial statements
include the accounts of Blonder Tongue Laboratories, Inc. and subsidiaries as
discussed below. Significant intercompany accounts and transactions have been
eliminated in consolidation.

(b) Reorganization and Recapitalization

         On October 3, 1995, the Board of Directors and stockholders approved
the following actions in connection with the Company's initial public offering,
which actions were implemented on December 11, 1995:

         Authorized capital consisting of 25 million shares of $.001 par value
         common stock and 5 million shares of $.001 par value preferred stock.
         The preferred stock may be issued in one or more series with such
         rights, preferences and limitations as the Board of Directors of the
         Company may determine.

         Declared a 2,011 for 1 stock split for the common stock. The
         consolidated financial statements reflect the impact of the stock split
         for all periods presented.

         On December 11, 1995, the Company acquired Blonder Tongue
International, Inc. ("BTI"). BTI was an S Corporation formed in 1994 by the
stockholders of the Company. The acquisition was consummated by contribution of
BTI's shares to the Company. The acquisition was accounted for at historical
cost similar to a pooling of interests, due to the common control exercised over
the entities by related parties. As a result of the acquisition of BTI, the S
Corporation elections for both BTI and the Company automatically terminated on
December 11, 1995. See Note 13.

         In September 1996, BTI closed its sales office located in Barcelona,
Spain. The closure did not have a material impact on the Company's operating
results.

(c) Inventories

         Inventories are stated at the lower of cost, determined by the
first-in, first-out ("FIFO") method, or market.

(d) Property, Plant and Equipment

         Property, plant and equipment are stated at cost. The Company provides
for depreciation generally on the straight-line method based upon estimated
useful lives of 3 to 5 years for office equipment, 5 to 7 years for furniture
and fixtures, 6 to 10 years for machinery and equipment, 10 to 15 years for
building improvements and 40 years for the manufacturing and administrative
office facility.

(e) Income Taxes

         Prior to December 11, 1995, the Company was treated as an S Corporation
under provisions of the Internal Revenue Code. Under these provisions, all
earnings and losses of the Company were reported on the federal income tax
returns of the stockholders. Accordingly, no provisions had been made for
federal income taxes. In January, 1994, the Company elected to be taxed as a
small business corporation in the state of New Jersey. The 1995 consolidated
financial statements reflect a state income tax provision only.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                    (In thousands, except per share amounts)

         The Company accounts for income taxes under the provisions of Statement
of Financial Accounting Standards No. 109, "Accounting for Income Taxes."
Deferred income taxes are provided for temporary differences in the recognition
of certain income and expenses for financial and tax reporting purposes.
Valuation allowances are established when necessary to reduce deferred tax
assets to the amount expected to be realized.

(f) Intangible Assets

         Intangible assets totaling $1,617 and $1,706 as of December 31, 1997
and 1996, respectively, consist of goodwill, prepaid licensing fees, and
acquired patent rights, and are carried at cost less accumulated amortization.
Amortization is computed utilizing the straight-line method over the estimated
useful life of the respective asset, 3 to 15 years. Amortization expense was
$206, $303 and $52 for 1997, 1996 and 1995, respectively.

(g) Long-Lived Assets

         Statement of Financial Accounting Standards No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of"
("SFAS 121"), was adopted as of January 1, 1996. SFAS 121 standardized the
accounting practices for the recognition and measurement of impairment losses on
certain long-lived assets based on non-discounted cash flows. The adoption of
SFAS 121 was not material to the results of operations or financial position.

(h) Statements of Cash Flows

         For purposes of the consolidated statements of cash flows, the Company
considers all highly liquid debt instruments with a maturity of less than three
months at purchase to be cash equivalents. The Company did not have any cash
equivalents at December 31, 1997, 1996 and 1995.

(i) Research and Development

         Research and development expenditures for the Company's projects are
expensed as incurred.

(j) Revenue Recognition

         The Company records revenues when products are shipped. Customers do
not have a right to return products shipped.

(k) Earnings Per Share

         During 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, "Earnings per Share" ("SFAS 128"),
which provides for the calculation of "basic" and "diluted" earnings per share.
This Statement, effective for financial statements issued for periods ending
after December 15, 1997, requires restatement of all prior-period earnings per
share data presented. Basic earnings per share includes no dilution and is
computed by dividing net earnings by the weighted average number of common
shares outstanding for the period. Diluted earnings per share reflect, in
periods in which they have a dilutive effect, the effect of common shares
issuable upon exercise of stock options. All periods presented have been
restated to comply with the provisions of SFAS 128.

                    (In thousands, except per share amounts)

(l) Treasury Stock

         Treasury Stock is recorded at cost. Gains and losses on disposition are
recorded as increases or decreases to additional paid-in capital with losses in
excess of previously recorded gains charged directly to retained earnings.

(m) Pro Forma Presentations

         The pro forma income tax provision has been calculated as if the
Company were taxable as a C Corporation under the Internal Revenue Code for all
periods presented.

(n) Significant Risks and Uncertainties

         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 those estimates.

         Approximately 68% of the Company's employees are covered by a three
year collective bargaining agreement, which expires in February, 1999.

         The Company estimates that Headend products accounted for approximately
80% of the Company's revenues in 1997, 84% in 1996 and 90% in 1995. Any
substantial decrease in sales of Headend products could have a material adverse
effect on the Company's results of operations and financial condition.

         The Company purchases several products from sole suppliers for which
alternative sources are not available, such as the VideoCipher(R) and
DigiCipher(R) encryption systems manufactured by General Instrument Corporation,
which are standard encryption methodology employed on U.S. C-Band and Ku-Band
transponders and EchoStar digital satellite receiver decoders, which are
specifically designed to work with the DISH Network(TM). An inability to timely
obtain sufficient quantities of these components could have a material adverse
effect on the Company's operating results. The Company does not have a supply
agreement with General Instrument Corporation or any other supplier. The Company
submits purchase orders to its suppliers on an as- needed basis.

(o) New Accounting Pronouncements

         In June 1997, SFAS 130, "Reporting Comprehensive Income," and SFAS 131,
"Disclosures About Segments of an Enterprise and Related Information," were
issued. SFAS 130 addresses standards for reporting and display of comprehensive
income and its components and SFAS 131 requires disclosure of reportable
operating segments. In February 1998, SFAS 132, "Employer's Disclosures About
Pensions and Other Postretirement Plans" was issued. SFAS 132 standardizes
pension disclosures. These statements are effective in 1998. The Company will be
reviewing these pronouncements to determine their applicability to the Company,
if any.

Note 4 - Debt

         
In October, 1997, the Company executed a new $15 million revolving line
of credit with its bank, on which funds may be borrowed at the bank's overnight
base rate ("OBR") plus a margin ranging from .95% to 2.45%, depending upon the
calculation of certain financial covenants (7.7% at December 31, 1998). As of
December 31, 1997, the Company had no balance outstanding under the line of
credit. The line of credit is collateralized by a security interest in all of
the Company's assets. The agreement contains restrictions that require the
Company to maintain certain financial ratios as well as restrictions on the
payment of dividends. In addition, the Company has an acquisition loan
commitment which may be drawn upon by the Company to finance acquisitions in
accordance with certain terms. The acquisition loan commitment had been $15
million until March, 1998 when it was increased to $20 million to accommodate
the acquisition of Scientific's Interdiction Business (See Note 16). Funds may
be borrowed under the acquisition loan commitment at OBR plus a margin ranging
from 1.25% to 2.75%, depending upon the calculation of certain financial
covenants. At December 31, 1997, there was no balance outstanding under the
acquisition loan commitment and as of March 26, 1998, there was $19 million
outstanding under the acquisition loan commitment. The line of credit and the
acquisition loan commitment expire on June 30, 1999.

         The average amount outstanding on the line of credit during 1997 was
$859 at a weighted average interest rate of 8.20%. The maximum outstanding under
this facility was $1,255 in 1997.

Note 5 - Commitments and Contingencies

Leases

         The Company leases certain factory and automotive equipment under
noncancellable operating leases expiring at various dates through October 2001.
The Company also leased its facility and was generally obligated under the
facility leases to pay additional amounts based on real estate taxes, utilities,
insurance and common area maintenance charges. The Company leased its primary
manufacturing and administrative office facility from a partnership whose only
operations consisted of leasing this facility to the Company. The Company had a

interest in the partnership and the remaining 51% interest in the partnership
was held by an unrelated third party. The Company accounted for its interest in
the partnership using the equity method. Lease payments to this partnership were
approximately $605 in 1995.

   In 1995, the Company entered into an agreement to purchase the remaining 51%
interest of the partnership and thereby acquired the manufacturing and
administrative office facility for $633 in cash plus the payment of two
mortgages in the amount of $3,728. The Company made these payments from the
proceeds of its initial public offering and accounted for the purchase of the
partnership interest as an acquisition of the building since it owns the
building outright upon purchase of the remaining partnership interest.

         Future minimum rental payments, required for all noncancellable leases
are as follows:

Litigation

         On October 18, 1996, the Company was served with a complaint in a
lawsuit filed by Scientific-Atlanta, Inc. ("Scientific") in the United States
District Court for the Northern District of Georgia alleging patent infringement
by the Company's VideoMask(TM) interdiction product. The complaint requested an
unspecified amount of damages and injunctive relief.

         Following the Company's acquisition of the assets and technology rights
of Scientific's interdiction business, Scientific's lawsuit against the Company
was dismissed with prejudice (See Note 16).

Note 6 - Benefit Plans

Defined Contribution Plan

         The Company has a defined contribution plan covering all full time
non-union employees qualified under Section 401(k) of the Internal Revenue Code,
in which the Company matches a portion of an employee's salary deferral. The
Company's contributions to this plan were $59, $54 and $46 for the years ended
December 31, 1997, 1996 and 1995, respectively.

Note 7 - Related Party Transactions

         On July 22, 1993, the Company issued a $912 note to a stockholder, who
is also the Company's President, Chief Executive Officer and Chairman of the
Board, pertaining to the purchase of 2,040 shares of common stock. Principal
payments on this note are due annually through July, 1996 with interest at
3.62%. Upon completion of the offering, the final payment of this note was
prepaid.

         In addition, the Company had a special bonus agreement whereby the
stockholder was paid net after-tax bonuses of $291, $281 and $272 over a three
year period due annually, through July, 1996.

         On January 1, 1995, the Company entered into a consulting and
non-competition agreement for a period of five years with a director, who is
also the largest stockholder. During this period, the director will provide
consulting services on various operational and financial issues and is currently
paid at an annual rate of $130 but in no event is such amount permitted to
exceed $150. The director also agreed to keep all Company

information confidential and will not compete directly or indirectly with the
Company for the term of the agreement and for a period of two years thereafter.

Note 8 - Concentration of Credit Risk

         Financial instruments that potentially subject the Company to
significant concentrations of credit risk consist principally of cash deposits
and trade accounts receivable.

         The Company maintains cash balances at several banks located in the
northeastern United States. As part of its cash management process, the Company
periodically reviews the relative credit standing of these banks.

         Credit risk with respect to trade accounts receivable is concentrated
with ten of the Company's customers. These customers accounted for approximately
64% and 61% of the Company's outstanding trade accounts receivable at December
31, 1997 and 1996, respectively. These customers are distributors of
telecommunications and private cable television components, and providers of
private cable television service. The Company performs ongoing credit
evaluations of its customers' financial condition, uses credit insurance and
requires collateral, such as letters of credit, to mitigate its credit risk. The
deterioration of the financial condition of one or more of its major customers
could adversely impact the Company's operations.

         For the year ended December 31, 1997, the Company's largest customer
accounted for approximately 16% of the Company's sales. At December 31, 1997,
this customer accounted for approximately 16% of the Company's outstanding trade
accounts receivable. Management believes these amounts to be collectible. A
different customer accounted for approximately 17% of the Company's sales in
1996 while a third customer accounted for approximately 18% of the Company's
sales in 1995.

Note 9 - Stockholders' Equity

         In December, 1995, the Company sold 2,200 shares of Common Stock at a
price of $9.50 per share in a public offering which generated net proceeds of
approximately $18,334. The proceeds were used to repay outstanding bank debt,
purchase the Company's manufacturing facility, make certain S Corporation
distributions and for working capital.

         In January, 1996, an additional 182 shares of Common Stock were sold at
a price of $9.50 per share pursuant to the exercise of the underwriters'
over-allotment option which generated net proceeds of approximately $1,606.

Stock Repurchase Program

         On April 1, 1997, the Company announced that its Board of Directors
authorized management to purchase up to 100 shares of its common stock.
Purchases will be made from time to time in the open market, and it is expected
that the funding of this program will come from operating cash flow and existing
bank facilities. As of December 31, 1997, the Company had repurchased 40 shares
under this new program.

Note 11 - Acquisition

         In 1993, the Company acquired the assets of MAR Associates, a company
engaged in research, development, manufacturing, and sales of electronic
components used in low power television transmission and microwave- link signal
transmission. The purchase price of $360 was paid in cash and the assumption of
certain liabilities. Additionally, the Company agreed to grant the former owners
options to purchase 132 shares of the Company's stock, for a nominal amount,
contingent upon the acquired company's meeting certain performance targets. In
October, 1994, the acquired company met the performance requirements, and the
Company granted the stock options and recorded goodwill of $342 as additional
consideration. The options were valued at the estimated fair market value at
date of grant. In March 1995, the former owners notified the Company of their
intention to exercise the options by tendering the cash required under the
purchase agreement. However, the former stockholders did not execute the
stockholders agreement required by the purchase agreement until October 10,
1995. Upon execution of the agreement, the Company issued 132 shares of common
stock and simultaneously therewith repurchased and retired 66 shares of the
common stock for an aggregate purchase price of $347 ($5.31 per share).

Note 12 - Stock Option Plans

         In 1994, the Company established the 1994 Incentive Stock Option Plan
(the "1994 Plan"). The 1994 Plan provides for the granting of Incentive Stock
Options to purchase shares of the Company's common stock to officers and key
employees at a price not less than the fair market value at the date of grant as
determined by the compensation committee of the Board of Directors. The maximum
number of shares available for issuance under the plan was 298. Options become
exercisable as determined by the compensation committee of the Board of
Directors at the date of grant. Options expire ten years from the date of grant.

         Also, in 1994, the Company granted non-qualified options for 6 shares
to an employee of BTI. These options expired during 1996 as a result of the
termination of the employee.

         In October, 1995, the Company's Board of Directors and stockholders
approved the 1995 Long Term Incentive Plan (the "1995 Plan"). The 1995 Plan
provides for grants of "incentive stock options" or nonqualified stock options,
and awards of restricted stock, to executives and key employees, including
officers and employee Directors. The 1995 Plan is administered by the
Compensation Committee of the Board of Directors, which determines the optionees
and the terms of the options granted under the 1995 Plan, including the exercise
price, number of shares subject to the option and the exercisability thereof, as
well as the recipients and number of shares awarded for restricted stock awards;
provided, however, that no employee may receive stock options or restricted
stock awards which would result, separately or in combination, in the
acquisition of more than 100 shares of Common Stock of the Company under the
1995 Plan. The exercise price of incentive stock options granted under the 1995
Plan must be equal to at least the fair market value of the Common Stock on the
date of grant. With respect to any optionee who owns stock representing more
than 10% of the voting power of all classes of the Company's outstanding capital
stock, the exercise price of any incentive stock option must be equal to at
least 110% of the fair market value of the Common Stock on the date of grant,
and the term of the option may not exceed five years. The term of all other
incentive stock options granted under the 1995 Plan may not exceed ten years.
The aggregate fair market value of Common Stock (determined as of the date of
the option grant) for which an incentive stock option may for the first time
become exercisable in any calendar year may not exceed $100. The exercise price
for nonqualified stock options is established by the Compensation Committee, and
may be more or less than the fair market value of the Common Stock on the date
of grant.

         Generally, options granted under the 1995 Plan are exercisable over the
term of the option, as provided by the Compensation Committee. Upon any merger
or consolidation, if the Company is not the surviving corporation, all
outstanding options granted shall terminate unless such options are assumed or
other options are substituted therefor by the successor corporation, or the
vesting of such shares is accelerated by the Compensation Committee.

         Under the 1995 Plan awards may be made to key executive employees of
restricted stock which is forfeitable unless the employee remains in the employ
of the Company for five years and does not violate other terms of the award,
such as non-transferability. Exceptions to forfeiture are provided for the cases
of retirement at age 65 or death while in employment. No restricted shares have
been awarded under the 1995 Plan.

         Stockholders have previously approved a total of 500 shares of common
stock for issuance under the 1995 Plan, as amended to date. In September, 1997,
the Board of Directors approved an increase in the number of shares available
for issuance under the 1995 Plan from 500 to 750, subject to stockholder
approval at the 1998 Annual Meeting of Stockholders.

         In December, 1995, the stockholders of the Company approved the
adoption of the Company's 1996 Director Option Plan (the "1996 Plan"). Under the
1996 Plan, Directors who within the preceding 12 months have not been employed
by the Company and have not served as a consultant to the Company where annual

compensation exceeds $100, are eligible to receive options to purchase 0.5
shares of the Company's Common Stock for each year of service on the Board. The
exercise price for such shares is the fair market value thereof on the date of
grant (which is December 31 of each year) and the options are subject to a
one-year vesting requirement. The options become exercisable, in whole or in
part, during the second through sixth years from the date of grant. Under the
1996 Plan the grant of options is automatic to each eligible Director serving on
December 31 of any year provided the Director had served in such capacity since
June 30 of such year. A maximum of 25 shares may be awarded under the 1996 Plan
which expires January 2, 2006. The plan is administered by a committee presently
comprised of James A. Luksch and Robert J. Palle, Jr.

         During October, 1997, subject to stockholder approval, the Board of
Directors amended the 1996 Plan to provide that it would be administered by the
Board of Directors rather than the 1996 Plan Committee, and that rather than
providing for annual automatic grants of options for a specified number of
shares to all non-employee Directors, the Board would have the power to grant
options to non-employee Directors at its discretion from time to time to
purchase the number of shares of Common Stock determined by the Board; provided,
however, that no Director would be permitted to receive options to purchase more
than 2 shares of Common Stock in any one calendar year.

         During December, 1997, the Board of Directors adopted the Amended and
Restated 1996 Director Option Plan (the "Amended 1996 Plan") subject to
stockholder approval. The Amended 1996 Plan incorporates the amendments to the
1996 Plan the Board had approved in October, 1997, as well as certain additional
amendments, and restates the 1996 Plan as amended. Under the Amended 1996 Plan,
Directors who are not currently employed by the Company or any subsidiary of the
Company and have not been so employed within the preceding six months are
eligible to receive options from time to time to purchase the number of shares
of Common Stock determined by the Board; provided, however, that no Director is
permitted to receive options to purchase more than 5 shares of Common Stock in
any one calendar year. The exercise price for such shares is the fair market
value thereof on the date of grant, and the options vest as determined in each
case by the Board of Directors. Options granted under the Amended 1996 Plan must
be exercised within 10 years from the date of grant. A maximum of 100 shares of
Common Stock are subject to issuance under the Amended 1996 Plan. The plan will
be administered by the Board of Directors. Also subject to stockholder approval
and in keeping with the terms of the Amended 1996 Plan, in 1997 no Director
received the grant of an option to purchase 0.5 shares of Common Stock at year
end provided for in the original 1996 Plan.

         In 1996, the Board of Directors granted a non-plan, non-qualified
option for 10 shares to an individual, who was not an employee or director of
the Company at the time of the grant. The option is exercisable at $10.25 and
expires in 2006.

Note 13 - Income Taxes

         Prior to December 11, 1995, with the consent of its stockholders, the
Company elected to be treated as an S Corporation under the provisions of the
Internal Revenue Code. Under these provisions, all earnings and losses of the
Company were reported on the federal income tax returns of the stockholders.
Accordingly, no provision for federal income taxes had been made. In January
1994, the Company elected to be taxed as a small business corporation in the
State of New Jersey. The consolidated financial statements for the fiscal year
ended December 31, 1995 reflect state income tax provisions only.

         The provision for income taxes for the period January 1 through
December 10, 1995 was $177 as the Company was still treated as an S Corporation.
On December 11, 1995, the Company's S election was terminated and, accordingly,
the Company was subject to federal income taxes. Upon termination of the S
election, the Company recorded a $587 charge related to net deferred tax
liabilities. The pro forma income taxes represent the taxes that would have been
reported as Federal, State and local income taxes had the Company accounted for
its income taxes under Statement of Financial Accounting Standards No. 109 as a
C Corporation. The effective rate utilized for all periods presented was 40%.

         Upon the completion of the offering, the Company declared a
distribution equal to the 1995 taxable S Corporation income which was paid from
the proceeds of the offering. At the date of the termination, the Company had
approximately $1,760 of previously untaxed income as a result of change in tax
accounting methods. The Company recorded a tax liability for the taxes due
(which is payable over 6 years) resulting from this change. The estimated tax
liability was approximately $704 (using an effective rate of 40%).

          Significant components of the Company's deferred tax assets and
liabilities are as follows:

Note 16 - Subsequent Event

         On March 26, 1998, the Company acquired all of the assets and
technology rights of the interdiction business (the "Interdiction Business") of
Scientific-Atlanta, Inc. ("Scientific") for a purchase price consisting of (i)
$19 million in cash, (ii) 67,889 shares of the Company's common stock, (iii) a
warrant to purchase 150,000 additional shares of the Company's common stock at
an exercise price of $14.25 per share and (iv) assumption by the Company of
certain obligations under executory contracts with vendors and customers and
certain warranty obligations and current liabilities of the Interdiction
Business. The Interdiction Business generated approximately $16 million in
revenues for the prior twelve month period. The Company believes that

serve the franchised cable market,

will supplement the Company's VideoMask(TM) products, which are primarily
focused on the Private Cable market. In addition, the Company expects that the
technology acquired as part of the Interdiction Business will enhance its
ability to design products that meet the specific needs of all cable providers,
while improving its position in the franchised cable market. Scientific will
provide certain manufacturing, consulting and other transition services to the
Company pursuant to agreements executed by the parties during a limited period
following the acquisition in order to permit the Company to fulfill sales orders
of the Interdiction Business for the transition period following the closing.

         In addition, under the terms of the purchase agreement with Scientific,
the Company is obligated to file a registration statement with the Securities
and Exchange Commission to register the shares of common stock issued to
Scientific and underlying the warrant held by Scientific as part of the purchase
price for the Interdiction Business within 90 days after the closing of the
acquisition.

Agreement, also issue one or more letters of credit ("Letters of Credit") for

Credit shall be reduced by the aggregate amounts drawn and available to be drawn
at any time under all outstanding Letters of Credit. In no event shall the
aggregate amount available to be drawn on all outstanding Letters of Credit plus
the outstanding principal balance of Line of Credit Loans exceed the Line of
Credit Commitment. The duration of any Letters of Credit shall not extend beyond
the Termination Date without the written consent of the Bank.

                               (2) Issuance of Letters of Credit. Subject to the

outstanding under the Line of Credit at an annual rate equal at all times to the
Line of Credit Adjusted Overnight Base Rate, which rate shall change
simultaneously and automatically upon each change in the Bank's Overnight Base
Rate. Interest on the aggregate outstanding principal under the Line of Credit
shall be payable monthly on first day of each calendar month commencing with the

                           (d) Line of Credit Note. The obligations of the
Borrower to repay the aggregate outstanding principal under the Line of Credit
and to pay accrued interest thereon shall be evidenced by a Third Amended and

receivable. If the Bank becomes entitled to claim any additional amounts
pursuant to this subsection, it shall promptly notify the Borrower of the event
by reason of which it has become so entitled. The good faith determination as to
any additional amounts payable pursuant to the foregoing sentence by the Bank
shall be conclusive in the absence of manifest error.

                  2.5 Determinations. In making the determinations contemplated
by Section 2.4 hereof the Bank may make such estimates, assumptions, allocations
and the like that it, in good faith, determines to be appropriate. All such
determinations shall be final, binding and conclusive upon the Borrower, except
to the extent of any manifest error in computation or transmission, however, the
Bank will permit the Borrower to rebut such determinations if it does so in
writing, with appropriate evidence thereof, within ten (10) Business Days from
the date of notification thereof by the Bank. The Bank shall furnish to the
Borrower a certificate outlining in reasonable detail the computation of any
amounts claimed by it under Section 2.4 and the assumptions underlying such
computations, provided that the failure to deliver a certificate shall not
affect the Bank's right to such amounts, but shall extend the time for the
Borrower to respond thereto as required above.

                  2.6 Payments and Computations. All amounts payable by the
Borrower to the Bank under this Agreement or the Notes shall be paid directly to
the Bank in immediately available funds at the address of the Bank set forth in
Section 10.2 hereof or at such other address of which the Bank shall give notice
to the Borrower pursuant to Section 10.2 hereof. The Bank is authorized to
charge any account of the Borrower at the Bank for any payment due by the
Borrower under this Agreement or any of the Notes. All computations of interest
hereunder shall be made by the Bank on the basis of a year of 360 days for the
actual number of days elapsed. All payments under each of the Notes shall be
applied first to the payment of interest due and payable thereunder and then to
the reduction of the outstanding principal balance thereof.

                  2.7 Borrowing. The Borrower shall notify the Bank of each
proposed borrowing under the Line of Credit not later than 2:30 p.m.,
Philadelphia, Pennsylvania time on the day of the proposed borrowing.

                  2.8 Prepayment and Repayment. The Borrower shall pay a
prepayment premium with respect to voluntary or involuntary prepayments of Loans
bearing interest at a fixed rate equal to the difference between (x) the
aggregate amount of interest which would otherwise have been payable on such
prepaid amount from the date of prepayment to the date when such prepaid amount
was due (but, with respect to the Existing Real Estate Loan, in no event beyond
the date on which interest on the Existing Real Estate Loan converts from a
fixed rate to a floating rate as prescribed in Section 2.2(b) above, unless the
interest rate is thereafter fixed in accordance with such Section), unless the
parties have



                                     - 14 -

<PAGE>



agreed to a new fixed rate of interest to be applicable after such date and (y)
the aggregate amount of interest which the Bank would earn if such prepaid
amount were invested at the Treasury Rate Security Yield from the date of
prepayment to the date when such prepaid amount was due (but, with respect to
the Existing Real Estate Loan, in no event beyond the date on which interest on
the Existing Real Estate Loan converts from a fixed rate to a floating rate as
prescribed in Section 2.2(b) above, unless the interest rate is thereafter fixed
in accordance with such Section), unless the parties have agreed to a new fixed
rate of interest to be applicable after such date, which difference in interest
earnings shall be discounted to present value at the Treasury Rate Security
Yield. The term, "Treasury Rate Security Yield", means the bond equivalent yield
to maturity available on the secondary market on a Treasury Security with a
maturity as close as possible to the scheduled maturity of the prepaid amount
and a coupon as close as possible to the bond equivalent yield. The Bank's
determination of the amount of any prepayment premium will be conclusive and
binding absent manifest error, however, the Bank will permit the Borrower to

                           (c) To the best of the Borrower's knowledge, after
reasonable inquiry, no real property owned or occupied by the Borrower has ever

reasonably require, and pay all premiums on the policies for all such insurance
when and as they become due and take all other actions necessary to maintain
such policies in full force and effect at all times. The insurance specified in

enforceability of any material term or provision of any of the Loan Documents is

<PAGE>



covered by insurance; or (ii) for injunctive or declaratory relief which would

<PAGE>



Loans, all interest and fees accrued and unpaid thereon, and all other amounts
and Obligations payable by the Borrower under this Agreement and the other Loan
Documents shall immediately become due and payable in full, all without protest,
presentment, demand, or further notice of any kind to the Borrower, all of which
are expressly waived by the Borrower;

                           (c) If any of the Obligations shall be due and
payable or any one or more Events of Default shall have occurred, the Bank shall
have the right, in addition to all other rights and remedies available to it,
without notice to the Borrower, to apply toward and set-off against and apply to
the then unpaid balance of the Notes and the other Obligations any items or
funds held by the Bank, any and all deposits (whether general or special, time
or demand, matured or unmatured, fixed or contingent, liquidated or
unliquidated) now or hereafter maintained by the Borrower for its own account
with the Bank, and any other indebtedness at any time held or owing by the Bank
to or for the credit or the account of the Borrower. For such purpose the Bank
shall have, and the Borrower hereby grants to the Bank, a first lien on all such
deposits. The Bank is hereby authorized to charge any such account or
indebtedness for any amounts due to the Bank. Such right of set-off shall exist
whether or not the Bank shall have made any demand under this Agreement, the
Notes or any other Loan Document and whether or not the Notes and the other
Obligations are matured or unmatured. The Borrower hereby confirms the Bank's
lien on such accounts and right of set-off, and nothing in this Agreement shall
be deemed any waiver or prohibition of such lien and right of set-off.

                  9.2 Further Remedies. Upon the occurrence of any one or more
Events of Default, the Bank may proceed to protect and enforce its rights under
this Agreement and the other Loan Documents by exercising such remedies as are
available to the Bank in respect thereof under applicable law, either by suit in
equity or by action at law, or both, whether for specific performance of any
provision contained in this Agreement or any of the other Loan Documents or in
aid of the exercise of any power granted in this Agreement or any of the other
Loan Documents.

remedies of the Bank provided in this Agreement and the other Loan Documents are
cumulative and not exclusive of any right, power or remedy provided by law or
equity, and no failure or delay on the part of the Bank in the exercise of any
right, power, or remedy shall operate as a waiver thereof, nor shall any single
or partial exercise of any right, power, or remedy preclude other or further
exercise thereof, or the exercise of any other right, power or remedy.

                           (a) Generally. This Agreement (i) shall be binding
upon the Borrower and the Bank and their respective successors and assigns, and
(ii) shall inure to the benefit of the Borrower and the Bank and its respective
successors and assigns, provided, however, that the Borrower may not assign its
rights hereunder or any interest herein without the prior written consent of the
Bank, and any such assignment or attempted assignment by the Borrower shall be
void and of no effect with respect to the Bank.

                           (b) Participations. The Bank may from time to time
sell or otherwise grant participations in the Loans and the Notes, and the
holder of any such participation, if the participation agreement so provides,
(i) shall, with respect to its participation, be entitled to all of the rights
of the Bank and (ii) may exercise any and all rights of setoff or banker's lien
with respect thereto, in each case as fully as though the Borrower were directly
indebted to the holder of such participation in the amount of such
participation. The Bank may disclose to prospective participants such
information regarding the Borrower's affairs as the Bank possesses. The Bank
shall give notice to the Borrower of the grant of such participations; however,
the failure to give such notice shall not affect any of the Bank's rights
hereunder.

                  10.13 Severability of Provisions. Any provision in this
Agreement that is held to be inoperative, unenforceable, voidable, or invalid in
any jurisdiction shall, as to that jurisdiction, be ineffective, unenforceable,
void or invalid without affecting the remaining provisions, and to this end the
provisions of this Agreement are declared to be severable.

                  10.14 Consent to Jurisdiction and Service of Process. The
Borrower irrevocably appoints each and every officer of the Borrower as its
attorneys upon whom may be served, by regular or certified mail at the address
set forth in Section 10.2 hereof, any notice, process or pleading in any action
or proceeding against it arising out of or in connection with this Agreement or
any of the other Loan Documents; and the Borrower hereby (i) consents that any
action or proceeding against it be commenced and maintained in any court within
the Commonwealth of Pennsylvania or in the United States District Court for the
Eastern District of Pennsylvania by service of process on any such officer; (ii)
agrees that the courts of the Commonwealth of Pennsylvania and the United States
District Court for the Eastern District of Pennsylvania shall have jurisdiction
with respect to the subject matter hereof and the person of the Borrower and the
Collateral, and (iii) waives any objection that such Borrower may now or
hereafter have as to the venue of any such suit, action or proceeding brought in
such a court or that such court is an inconvenient forum. Notwithstanding the
foregoing, the Bank, in its absolute discretion may also initiate proceedings in
the courts of any other jurisdiction in which the Borrower may be found or in
which any of its properties or the Collateral may be located.

                  10.15 Indemnification

                           (a) If, after receipt of any payment of all or any
part of the Obligations, the Bank is compelled to surrender such payment to any
Person or entity for any reason (including, without limitation, a determination
that such payment is void or voidable as a preference or fraudulent conveyance,
an impermissible setoff, or a diversion of trust funds), then this Agreement and
the other Loan Documents shall continue in full force and effect, and the
Borrower shall be liable for, and shall indemnify, defend and hold harmless the
Bank with respect to the full amount so surrendered.

                           (b) The Borrower shall indemnify, defend and hold
harmless the Bank with respect to any and all claims, expenses, demands, losses,
costs, fines or liabilities of any kind, including reasonable attorneys' fees
and costs, arising from or in any way related to (i) acts or conduct of the
Borrower or any of the Other Loan Parties under, pursuant to or related to this
Agreement and the other Loan Documents, (ii) Borrower's or any Other Loan
Party's breach or violation of any representation, warranty, covenant or
undertaking contained in this Agreement or the other Loan Documents, and (iii)
Borrower's or any other Loan Party's failure to comply with any or all laws,
statutes, ordinances, governmental rules, regulations or standards, whether
federal, state, or local, or court or administrative orders or decrees,
including without limitation those resulting from any Hazardous Materials or
dangerous environmental condition within, on, from, related to or affecting any
real property owned or occupied by the Borrower, unless resulting from the acts
or



                                     - 35 -

conduct of the Bank constituting gross negligence or willful misconduct.

                           (c) The provisions of this section shall survive the
termination of this Agreement and the other Loan Documents and shall be and
remain effective notwithstanding the payment of the Obligations, the
cancellation of any of the Notes, the release of any Encumbrance securing the
Obligations or any other action which the Bank may have taken in reliance upon
its receipt of such payment. Any cancellation of any of the Notes, release of
any Encumbrance or other such action shall be deemed to have been conditioned
upon any payment of the Obligations having become final and irrevocable.
