                                    PART I
 
ITEM 1.BUSINESS
 
GENERAL
 
        Scientific-Atlanta, Inc. (the "Company") provides its customers with
the products and services for advanced communications networks which deliver
voice, data and video. The Company's products connect information generators
with information users via broadband terrestrial and satellite networks, and
include applications for the converging cable, telephone, and data networks.
 
        The Company operates primarily in one business segment,
Communications, providing communications networks to a range of customers for
a variety of applications and providing network management and systems
integration for those networks. This segment represents over 90% of
consolidated sales, operating profit and identifiable assets.
 
        The Company has evolved from a manufacturer of electronic test
equipment for antennas and electronics for the cable industry to a producer of
a wide variety of products for terrestrial and satellite communications
networks, including digital video, voice and data communications products. The
Company's products include receivers, transmitters, distribution amplifiers,
modulators, demodulators, signal encoders and decoders, controllers, optical
amplifiers, source lasers, analog and digital set-tops, digital video
compression and transmission equipment, fiber optic distribution equipment,
and satellite earth station antennas. These products, and integrated systems
and networks using these and other products, are sold to CATV system
operators, telephone companies, communications carriers, communications
network operators, utility companies and multi-facility business organizations
which use communications satellites for intracompany communications. Sales are
also made to independent system integrators, distributors and dealers who
resell the products to some of the above types of customers.
 
        The Company sells transmission products, including RF (radio
frequency) amplifiers, line extenders, opto-electronic transmitters and
amplifiers, taps, and passives, which transmit signals via coaxial cable or
fiber optics from the cable operator to the end-user customer. The Company's
transmission products enable operators to transmit video and data over the
same network, with a reverse path for customers to communicate back to the
operator. Sales of RF distribution products constituted approximately 18% of
the Company's total sales for fiscal 1998, and approximately 19% and 21% of
such sales in fiscal years 1997 and 1996, respectively. The Company previously
announced that it planned to have production quantities of the new Prisma(TM)
Digital Transport product, an opto-electronics product, available in the first
quarter of fiscal 1999, but the availability of such production quantities is
expected to be delayed until the second quarter of fiscal 1999.
 
        The Company also sells modulators, demodulators and signal processors
for video and audio receiving stations (often referred to as "headend"
systems), products for distributing communications signals by coaxial cable
and fiber optics from headend systems to subscribers and set-top terminals
that enable television sets to receive all channels transmitted by system
operators.
 
        The Company's set-tops include units which are addressable from the
headend system so as to permit control of channel authorizations, including
authorizations for pay-per-view events, impulse ordering and automatic
recording of billing information at the cable operator's central facility, and
menu-driven volume controllable units. Sales of set-tops constituted
approximately 34% of the Company's total sales for fiscal year 1998, and
approximately 30% and 27% of such sales in each of fiscal years 1997 and 1996,
respectively. Proprietary software used in the terminals, as well as system
manager software at the headend system or at the transmission level, was
developed by the Company and is updated from time to time. The Company's new
Explorer(R) 2000 digital set-tops will enable subscribers to access new
services such as e-mail over television, video-on-demand, Web browsing,
Internet Protocol (IP) telephony, various types of electronic-commerce, and
more. For Explorer 2000 digital set-tops to be enabled to provide the above-
described services, the set-tops must be utilized in an advanced, interactive,
two-way, digital cable network, which the Company sells.
 
                                       1
<PAGE>
 
        The Company's products, both analog and digital, are being utilized by
the Company's traditional cable operator customers to upgrade their networks
to provide new services and by the telephone companies to build new video,
voice and data networks. They are also utilized by electric utilities in load
management systems which monitor and control power usage and monitor power
outages. The Company's products are also utilized by programmers and
broadcasters to transmit their programs to viewers.
 
        The Company's satellite earth stations receive and transmit signals
for video, voice and data and are utilized in satellite-based telephone, data
and television distribution networks. Some of these earth stations are part of
national and international communications systems which communicate by means
of a satellite with earth stations in other countries or with other earth
stations in the same national network. Earth stations in these systems may be
connected with local telephone, television or other terrestrial communications
networks. The Company's earth stations, signal encoders and decoders, packet
switches and controllers are also used in private business networks for the
exchange of audio, video and data via satellite among various office,
manufacturing and sales facilities and for the delivery of television
programming to hotels, motels and apartment complexes. The Company's data
communications product offerings include private interactive data systems
using VSAT (very small aperture terminal) technology.
 
        The Company designs, manufactures and sells digital video compression
communications products for use by television broadcasters and cable
operators. The Company's digital video compression products utilize the open
architecture MPEG-2 technology adopted by an international standards group, of
which the Company is a founding member. MPEG-2 digital equipment allows
headend, set-top and consumer electronics products and systems to operate
together across networks and in the home.
 
        The Company's satellite products and systems include tracking and
telemetry equipment, earth observation satellite ground stations, and
intercept systems. The Company produces telemetry instruments, radar
platforms, special receivers, special measurement devices and other equipment
used to track aircraft, missiles, satellites and other moving objects and to
communicate with and receive and record various measurements and other data
from the object. The Company's long experience with advanced satellite
tracking technologies has enabled it to offer a range of gateways, network
management centers, transceivers and services for the emerging low earth
orbiting (LEO) satellite communications markets. In addition, the Company has
coupled LEO satellite communications with other wireless and terrestrial
networks to offer two-way interactive solutions to the electric utility
industry for load control and energy management.
 
        See the Consolidated Financial Statements included in this Form 10-K
for the Company's annual sales, annual profits and total assets.
 
OTHER PRODUCTS AND SERVICES.
 
        The Company has consolidated most of its service functions into a
single service organization, with its goal being to ensure effective post-sale
service for customers using its products, whether such products are under
warranty or no longer under warranty. This service organization offers a
variety of maintenance and service contracts to companies using products
manufactured or sold by the Company, in addition to providing systems
integration, installation, and professional services. In April 1998, the
Company announced the creation of a partially-owned subsidiary, Advanced
Broadband System Services, Inc., which will provide a wide range of services
to the cable industry, including turnkey installation services for customers
such as Tele-Communications Inc. ("TCI").
 
MARKETING AND SALES
 
        The Company's products are sold primarily through its own sales
personnel who work out of offices in metropolitan Atlanta and other
metropolitan areas in the United States. Certain products are also marketed in
the United States through independent sales representatives and independent
distributors. In addition to direct sales by the Company, sales in foreign
countries are made through wholly-owned subsidiaries and branch offices, as
well as through independent distributors and independent sales
representatives. The Company's management personnel are also actively involved
in marketing and sales activities.
 
                                       2
<PAGE>
 
        The Company's international sales constituted 32% of the Company's
total sales for fiscal year 1998 and 37% and 36% of total sales in fiscal
years 1997 and 1996, respectively. Substantially all of these sales were
export sales. Foreign subsidiary sales were not material for any of these
three fiscal years. See Note 3 of the Notes to Consolidated Financial
Statements included in this Form 10-K. Sales to Europe were 14% of total sales
in fiscal 1998 and were 16% and 12% of total sales in fiscal 1997 and 1996,
respectively.
 
        Sales to Time Warner, Inc. and its affiliates were 11% of the
Company's total sales in fiscal 1998 and were 11% of total sales in fiscal
1997. Sales to MediaOne and its affiliates were 11% of the Company's total
sales in fiscal 1998 and were less than 10% of total sales in fiscal 1997. No
customer (or group of customers under common control) accounted for more than
10% of the Company's revenues in fiscal 1996.
 
BACKLOG
 
        The Company's backlog consists of unfilled customer orders believed to
be firm and long-term contracts which have not been completed. The Company's
backlog as of June 26, 1998, and June 27, 1997, was $486,144,000 and
$483,463,000, respectively.
 
        The Company believes that approximately 90% of the backlog existing at
June 26, 1998, will be shipped within the succeeding fiscal year. With respect
to long-term contracts, the Company includes in its backlog only amounts
representing orders currently released for production. The amount contained in
backlog for any contract or order may not be the total amount of the contract
or order. The amount of the Company's backlog at any time does not reflect
expected revenues for any fiscal period.
 
PRODUCT RESEARCH AND DEVELOPMENT AND PATENTS
 
        The Company conducts an active research and development program to
strengthen and broaden its existing products and systems and to develop new
products and systems. The Company's development strategy is to identify
products and systems which are, or are expected to be, needed by a substantial
number of customers in the Company's markets and to allocate a greater share
of its research and development resources to areas with the highest potential
for future benefits to the Company. In addition, the Company develops specific
applications related to its present technology. Expenditures in fiscal 1998,
1997 and 1996 were principally for development of commercial digital cable
products and satellite network products. In fiscal 1998, 1997 and 1996, the
Company's research and development expenses were approximately $111,546,000,
$114,344,000, and $95,299,000, respectively.
 
        The Company holds patents with respect to certain of its products and
actively seeks to obtain patent protection for significant inventions and
developments.
 
MANUFACTURING
 
        The Company develops, designs, fabricates, manufactures, assembles or
acquires its products. Manufacturing operations range from complete assembly
of a particular product by one individual or small group of individuals to
semi-automated assembly lines for volume production. Because many of the
Company's products include precision electronic components requiring close
tolerances, the Company maintains rigorous and exacting test and inspection
procedures designed to prevent production errors, and also constantly reviews
its overall production techniques to enhance productivity and reliability. The
Company's analog set-tops and taps and passives hardware for the CATV industry
are manufactured primarily by contract vendors with high-quality, high-volume
production facilities. In addition to such manufacturing by contract vendors,
the Company commenced its own manufacturing of set-top terminals in fiscal
year 1995 in its new Juarez, Mexico facility. In fiscal year 1997, the Company
completed a 124,000 square foot addition to its manufacturing facility in
Juarez, Mexico. The Company manufactures a variety of products in its Juarez,
Mexico facility, including a portion of its 8600x(TM) advanced analog set-
tops. During fiscal year 1998, the Company launched the production of its
 
                                       3
<PAGE>
 
Explorer 2000 set-top in the Juarez, Mexico facility. As announced in August
1998, the Company, during the second fiscal quarter of 1999, is increasing its
manufacturing capacity in Juarez, Mexico for the Explorer 2000 digital
interactive set-top. Also, as the Company announced in June 1998, during the
second quarter of fiscal 1999, it is transferring the RF amplifier product
line to the Juarez, Mexico manufacturing facility from the Norcross, Georgia
manufacturing facility. The transfer is expected to enable the Company to
remain cost competitive in the markets for RF amplifiers. In the same June
1998 announcement, the Company disclosed its decisions to move (i) its cable
headend manufacturing operation from its Vancouver, British Columbia facility
to its Norcross, Georgia manufacturing facility, and (ii) its satellite
services Network Operations Center (including the related research and
development facility) from Melbourne, Florida to Norcross, Georgia.
 
MATERIALS AND SUPPLIES
 
        The materials and supplies purchased by the Company are standard
electronic components, such as integrated circuits, wire, circuit boards,
transistors, capacitors and resistors, all of which are produced by a number
of manufacturers. Matsushita Electronic Components Co., Ltd. and its
affiliates manufacture analog set-tops for the Company and are a primary
supplier of those set-tops. Cablevision Electronics Co., Ltd and Zinwell
Corporation, Taiwanese companies, are primary suppliers of taps for the
Company. The Company also purchases aluminum and steel, including castings and
semi-fabricated items, produced by a variety of sources. The Company's primary
supplier of die castings for its RF distribution products is Premiere Die
Casting, Inc. Additionally, Motorola, Inc., Broadcom Corporation and SGS-
Thomson Microelectronics, Inc. are three of the Company's primary suppliers of
a variety of semi-conductor products, which are used as components in an array
of the Company's products, including its set-tops. The Company considers its
sources of supply to be adequate and is not dependent upon any single
supplier, except for Matsushita Electronic Components Co., Ltd. (and
affiliates), Cablevision Electronics Co., Ltd., Zinwell Corporation, Premiere
Die Casting, Inc., Motorola, Inc., Broadcom Corporation and SGS-Thomson
Microelectronics, Inc., for any significant portion of the materials used in
the products it manufactures or for the products it sells.
 
EMPLOYEES
 
        The Company employed approximately 5,736 regular full-time and part-
time employees and approximately 467 additional workers employed through
temporary employment agencies on June 26, 1998. The Company believes its
employee relations are satisfactory.
 
COMPETITION
 
        The businesses in which the Company is engaged are highly competitive.
The Company competes with companies which have substantially greater resources
and a larger number of products, as well as with smaller specialized
companies. Some of the Company's customers are in businesses closely related
to the production of such products and are, therefore, potential competitors
of the Company. The Company believes that its ability to compete successfully
results from its marketing strategy, engineering skills, product features,
product performance, ability to provide post-purchase services, ability to
provide quality products at competitive prices and broad coverage by its sales
personnel.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Stockholders of Scientific-Atlanta, Inc.:
 
        We have audited the accompanying consolidated statement of financial
position of Scientific-Atlanta, Inc. (a Georgia corporation) and subsidiaries
as of June 26, 1998 and June 27, 1997 and the related consolidated statements
of earnings and cash flows for each of the three years in the period ended June
26, 1998 appearing on pages 15, 25, and 27, respectively. These financial
statements and the schedule referred to below are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements and schedule based on our audits.
 
        We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the 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 financial statements referred to above present
fairly, in all material respects, the financial position of Scientific-Atlanta,
Inc. and subsidiaries as of June 26, 1998 and June 27, 1997 and the results of
their operations and their cash flows for each of the three years in the period
ended June 26, 1998 in conformity with generally accepted accounting
principles.
 
        Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule listed in Item
14(a)(2) of this Form 10-K is presented for purposes of complying with the
Securities and Exchange Commission's rules and is not part of the basic
financial statements. This schedule has been subjected to the auditing
procedures applied in the audits of the basic financial statements and, in our
opinion, fairly states in all material respects the financial data required to
be set forth therein in relation to the basic financial statements taken as a
whole.

REPORT OF MANAGEMENT
 
        The management of Scientific-Atlanta, Inc. (the Company) has the
responsibility for preparing the accompanying financial statements and for
their integrity and objectivity. The statements, which include amounts that are
based on management's best estimates and judgments, have been prepared in
conformity with generally accepted accounting principles and are free of
material misstatement. Management also prepared the other information in the
Form 10-K and is responsible for its accuracy and consistency with the
financial statements.
 
        The Company maintains a system of internal control over the preparation
of its published annual and interim financial statements. It should be
recognized that even an effective internal control system, no matter how well
designed, can provide only reasonable assurance with respect to the preparation
of reliable financial statements; further, because of changes in conditions,
internal control system effectiveness may vary over time.
 
        Management assessed the Company's system of internal control in
relation to criteria for effective internal control over the preparation of its
published annual and interim financial statements. Based on its assessment, it
is management's opinion that its system of internal control as of June 26, 1998
is effective in providing reasonable assurance that its published annual and
interim financial statements are free of material misstatement.
 
        As part of their audit of our financial statements, Arthur Andersen LLP
considered certain elements of our system of internal controls in determining
their audit procedures for the purpose of expressing an opinion on the
financial statements.
 
        The audit committee of the board of directors is composed solely of
outside directors and is responsible for recommending to the board the
independent public accountants to be retained for the year, subject to
stockholder approval. The audit committee meets three times each year to review
with management the Company's system of internal accounting controls, audit
plans and results, accounting principles and practices, and the annual
financial statements.

MANAGEMENT'S DISCUSSION OF CONSOLIDATED STATEMENT OF FINANCIAL POSITION
 
Scientific-Atlanta had stockholders' equity of $632.0 million and cash and cash
   equivalents of $175.4 million at June 26, 1998. The current ratio of 2.8:1
   at June 26, 1998 compared to 2.4:1 at June 27, 1997.
 
CASH AND CASH EQUIVALENTS at the end of 1998 were $175.4 million, up $68.2
   million over last year. Cash generated from earnings, reductions in
   inventory levels, the sale of two businesses and the issuance of stock
   exceeded expenditures for equipment, expansion of manufacturing capacity and
   increases in accounts receivable days sales outstanding in the fourth
   quarter of fiscal 1998 as compared to the prior year. Ending working
   capital, excluding cash and marketable securities, was $186.5 million, or
   15.8 percent of sales, as compared to $240.2 million or 20.6 percent of
   sales in the prior year.
 
MARKETABLE SECURITIES of $95.9 million consist of investments in common stock
   and are reported at market value. During fiscal 1998, the Company recorded a
   net unrealized gain on $93.8 million in other income from the adjustment of
   these investments from cost to the market value.
 
  Recently, equity markets throughout the world have experienced significant
  volatility. Marketable securities with a market value of $95.9 million at
  June 26, 1998 have increased in value to $101.0 million at September 14,
  1998. Management is not currently able to estimate the amount to be
  realized from the ultimate sale of these marketable securities.
 
RECEIVABLES were $254.4 million at year-end, compared to $238.2 million at the
   prior fiscal year-end. Average days sales outstanding were 75 in fiscal
   1998, approximately the same as the prior year. The allowance for doubtful
   accounts of $10.1 million increased $5.9 million due to a one-time provision
   of $5.9 million for receivables from customers in the Asia Pacific region
   which is currently experiencing currency and other economic crises.
 
INVENTORY turnover was 4.3 times in 1998, compared to 4.1 in the prior year.
   The improvement in inventory turnover was due to lower average inventory
   balances in 1998 as compared to 1997 reflecting management's effort to
   improve working capital by reducing inventory levels. In addition, the
   Company recorded a one-time provision of $26.4 million related to the
   restructuring and consolidation of certain satellite business units and
   worldwide manufacturing operations. See Management's Discussion of
   Consolidated Statement of Earnings.
 
CURRENT DEFERRED INCOME TAXES decreased $13.3 million due to mark-to-market net
   gain on marketable securities which is not taxable until the gain is
   realized which was partially offset by increases in non-deductible reserves.
 
OTHER CURRENT ASSETS of $13.1 million include prepaid taxes, other than income
   taxes, license fees, land held for sale, prepaid software maintenance fees
   and other miscellaneous prepaid expenses.
 
NET PROPERTY, PLANT AND EQUIPMENT decreased $6.4 million in 1998 due primarily
   to the sale of the interdiction and microwave businesses and disposals
   related to the restructuring and consolidation of worldwide manufacturing
   operations. Capital additions of $40.6 million included expenditures for
   equipment, and expansion of manufacturing capacity, primarily in Juarez,
   Mexico.
 
COST IN EXCESS OF NET ASSETS ACQUIRED decreased $2.4 million in 1998, from the
   amortization of the cost of businesses acquired in prior years and the
   write-off of costs associated with purchased technology in the satellite
   businesses which will no longer be utilized as a result of the restructuring
   and consolidation of certain satellite business units in fiscal 1998. See
   Management's Discussion of Consolidated Statement of Earnings.
 
OTHER ASSETS, which include license fees, investments, intellectual property,
   capitalized software development costs, cash surrender

MANAGEMENT'S DISCUSSION OF CONSOLIDATED STATEMENT OF FINANCIAL POSITION
(CONTINUED)
 
   value of company-owned life insurance and various prepaid expenses,
   increased $6.0 million in 1998 due primarily to capitalized software
   development costs and additional investments. See Notes 1 and 2.
 
TOTAL BORROWINGS at year-end amounted to $1.7 million, $0.9 million lower than
   the prior year. The borrowings include industrial development bonds and
   financing for equipment. Details of borrowings are shown in Note 8.
 
ACCOUNTS PAYABLE were $103.6 million at year-end, down from $123.7 million
   last year. The decrease reflects lower inventory levels at the end of
   fiscal 1998 as compared to the prior year. Days in accounts payable of 48
   in fiscal 1998 was approximately the same as fiscal 1997.
 
ACCRUED LIABILITIES of $139.0 million include accruals for restructuring and
   consolidation of manufacturing operations, compensation, warranty and
   service, customer down-payments, royalties and taxes, excluding income
   taxes. The increase in the accruals is due primarily to provisions relating
   to restructuring and the consolidation of manufacturing operations and
   certain satellite business units and other one-time charges. See
   Management's Discussion of Consolidated Statement of Earnings and Notes 4
   and 9 for additional information.
 
OTHER LIABILITIES of $48.5 million are comprised of deferred compensation,
   retirement plans, postretirement benefit plans, postemployment benefits and
   other miscellaneous accruals. See Note 10 for details.
 
STOCKHOLDERS' EQUITY was $632.0 million at the end of 1998, up $99.3 million
   over the prior year. Net earnings of $80.8 million and $30.7 million from
   the issuance of common stock pursuant to employee benefit plans were
   partially offset by dividend payments of $4.7 million and the repurchase of
   500,000 shares of the Company's stock for $7.5 million. See Note 19 for
   details.

MANAGEMENT'S DISCUSSION OF CONSOLIDATED STATEMENT OF EARNINGS
 
The Consolidated Statement of Earnings summarizes Scientific-Atlanta's
   operating performance over the last three years, during which time the
   Company has accelerated development of new products, particularly the
   development, deployment, production and qualification of the Company's
   interactive digital networks at customer sites in North America, and
   continued its expansion into international markets.
 
EARNINGS FROM CONTINUING OPERATIONS in 1998 were $80.8 million, or $1.02 per
   share as compared to $60.6 million, or $0.78 per share, in 1997. The
   Company's 1998 results contain several significant and non-recurring items.
   First, during the fourth quarter of 1998, the Company announced that it
   would implement a restructuring and consolidation of worldwide
   manufacturing operations to achieve reduced costs, improved efficiencies
   and better customer service. Production of the RF (radio frequency)
   amplifier is expected to be transferred from Norcross, Georgia to the
   Company's high volume, low cost manufacturing facility in Juarez, Mexico by
   October 1998. The Norcross manufacturing facility is expected to focus on
   medium-to-low-volume products requiring close engineering support. The
   production of cable headend equipment is planned to be consolidated in
   Norcross from Vancouver, British Columbia. This move is designed to improve
   efficiency and to more effectively manage the transition of analog to
   digital headend products. The Melbourne, Florida satellite services Network
   Operations Center (NOC) and research and development facility is scheduled
   to be relocated to Norcross. The Company's European headquarters has been
   moved from London, England to Frankfurt, Germany to better address market
   opportunities in continental Europe. The Far East regional headquarters
   have been transferred from Hong Kong to Singapore. The Company's Satellite
   Networks and Communications and Tracking Systems business units are being
   combined to capitalize on the combined resources provided by concentrated
   capabilities in networks, research and development, marketing and sales,
   and customer program management and services. As a result of the above, the
   Company recorded $76.2 million of restructuring and other one-time pre-tax
   charges in the fourth quarter of fiscal 1998. These charges include the
   impairment of assets, such as excess inventory related to the consolidation
   of manufacturing operations and the discontinuance of certain product
   models, costs to relocate production and the NOC, losses on contracts,
   costs to abandon facilities, charges to establish an allowance for doubtful
   accounts receivable from customers in the Asia Pacific region which is
   currently experiencing currency and other economic crises and environmental
   issues. The Company charged $33.6 million to cost of sales, $5.9 million to
   selling and administrative expenses, $23.4 million to restructuring expense
   and $13.3 million to other expense. The Company also recorded a one-time
   pre-tax gain of $94.0 million to adjust its investment in Broadcom
   Corporation to market value. Net earnings excluding these one-time special
   items were $68.5 million, or $0.87 per share. Earnings from continuing
   operations in 1997 were $60.6 million, as compared to $7.2 million in 1996.
   Earnings from continuing operations in 1996 included one-time, after-tax
   charges of $19.5 million for the resolution of an arbitration proceeding
   and $9.9 million for the write-off of purchased in-process technology.
   Higher sales volume and improved gross margins, which were the primary
   factors in the year-to-year increase, were offset partially by increased
   sales and administrative expenses and research and development expenses.
 
SALES of $1,181.4 million increased slightly over the prior year. Higher
   domestic sales volume of subscriber products, particularly advanced analog
   set-tops, and of transmission products, were offset by significant declines
   in sales to customers in the Asia Pacific and Europe regions. The weak
   Asian economy continued to negatively impact bookings and sales, and the
   Company does not anticipate that these conditions will improve
   significantly in the near term. Europe was impacted by a slow down in the
   U.K. In addition, a large customer in Europe decided to re-evaluate its
   cable strategy, which had the impact of halting orders. Sales in 1998 of
   satellite systems also declined as compared to 1997.
                                      17

MANAGEMENT'S DISCUSSION OF CONSOLIDATED STATEMENT OF EARNINGS (CONTINUED)
 
 
   During the fourth quarter of fiscal 1998, the Company began the rollout of
   advanced two-way digital cable systems which are real-time, interactive
   digital networks capable of advanced services such as video-on-demand,
   e-mail and Internet browsing, once such services are available. The Company
   plans to double the production capacity of its Explorer(R) 2000 digital
   set-tops in Juarez to one million units annually beginning in October 1998.
   The Company anticipates that sales of the Company's new digital products
   will have some negative impact on sales of analog set-tops.
 
   Sales of set-tops constituted approximately 34 percent of the Company's
   total sales in 1998, and approximately 30 percent and 27 percent of such
   sales in 1997 and 1996, respectively. Sales of RF products were
   approximately 18 percent of the Company's total sales in 1998, and
   approximately 19 percent and 21 percent of such sales in 1997 and 1996,
   respectively. International sales were 32 percent of total sales in 1998,
   as compared to 37 percent and 36 percent of such sales in 1997 and 1996,
   respectively.
 
   Sales of $1,168.2 million in 1997 increased 11 percent over the prior year.
   Higher domestic sales volume of subscriber products, particularly advanced
   analog set-tops, was the major contributor to the increase. Sales volume of
   distribution equipment, primarily RF products, also contributed to the
   increase. Sales in 1997 of satellite systems increased slightly over the
   prior year driven by sales of the Company's recently introduced PowerVu(TM)
   digital video systems. Sales volume of video game adapters declined as
   compared to the prior year.
 
COST OF SALES as a percent of sales increased 2.7 percentage points in 1998.
   Cost of sales in 1998 included one-time charges of $33.6 million for excess
   inventory related to the consolidation of manufacturing operations, the
   combination of the Satellite Networks and Communications and Tracking
   Systems business units, the discontinuance of certain models of products,
   estimated losses on a contract and other miscellaneous charges related to
   the restructuring and consolidation of worldwide manufacturing operations.
   Excluding these charges, cost of sales as a percent of sales decreased 0.1
   percentage point from 1997. The improvement of 0.1 percentage point
   reflects the continuing benefit from manufacturing in Juarez, negotiated
   procurement savings and improved yen exchange rates offset in part by lower
   volume of sales in the Asia Pacific region, which generally have higher
   margins than some other geographic regions, and margin decreases in
   distribution equipment from market pressures.
 
   Cost of sales as a percent of sales in 1997 decreased 3.4 percentage points
   from 1996. Improved margins reflect the impact of internal programs to
   improve quality and reduce cost, the ramp-up of the Juarez manufacturing
   facility, and favorable exchange rates on Japanese yen compared to the
   prior year. Favorable margin improvements were offset partially by
   increased volumes of certain subscriber products which have lower margins
   than some of the Company's other products.
 
   The materials and supplies purchased by the Company are standard electronic
   components, such as integrated circuits, wire, circuit boards, transistors,
   capacitors and resistors, all of which are produced by a number of
   manufacturers. Matsushita Electronic Components Co., Ltd. and its
   affiliates manufacture analog set-tops for the Company and are a primary
   supplier of those set-tops. Cablevision Electronics Co., Ltd. and Zinwell
   Corporation, Taiwanese companies, are primary suppliers of taps for the
   Company. The Company also purchases aluminum and steel, including castings
   and semi-fabricated items, produced by a variety of sources. The Company's
   primary supplier of die castings for its RF distribution products is
   Premiere Die Casting, Inc. Additionally, Motorola, Inc., Broadcom
   Corporation and SGS-Thomson Microelectronics, Inc. are three of the
   Company's primary suppliers of a variety of semi-conductor products, which
   are used as components in an array of the Company's products, including its
   set-tops. The

<PAGE>
 
MANAGEMENT'S DISCUSSION OF CONSOLIDATED STATEMENT OF EARNINGS (CONTINUED)
 
   Company considers its sources of supply to be adequate and is not dependent
   upon any single supplier, except for Matsushita Electronic Components Co.,
   Ltd. (and affiliates), Cablevision Electronics Co., Ltd., Zinwell
   Corporation, Premiere Die Casting, Inc., Motorola, Inc., Broadcom
   Corporation and SGS-Thomson Microelectronics, Inc., for any significant
   portion of the materials used in the products it manufactures or for the
   products it sells.
 
   Certain material purchases are denominated in Japanese yen and, accordingly,
   the purchase price in U.S. dollars is subject to change based on exchange
   rate fluctuations. Currently, the Company has forward exchange contracts to
   purchase yen to hedge a portion of its exposure on purchase commitments for
   a period of twelve months. See Note 1.
 
SALES AND ADMINISTRATIVE EXPENSES of $165.6 million in 1998 were $5.0 million
   higher than 1997. Sales and administrative expenses in 1998 include a one-
   time charge of $5.9 million to establish an allowance for doubtful accounts
   receivables from customers in the Asia Pacific region which is currently
   experiencing currency and other economic crises. Excluding this one-time
   charge, expenses were flat as compared to the prior year and remained at
   approximately 14 percent of sales. The Company is continuing to invest in
   opportunities to expand into international markets and introduce new
   products.
 
   Sales and administrative expenses of $160.6 million in 1997 increased $22.3
   million over the prior year. Increased selling expenses reflect costs
   associated with higher sales volumes, ongoing investments to support
   expansion into international markets, particularly in the Latin American
   region, and to support the introduction of new products. Administrative
   expenses increased as higher consulting fees, administrative expenses of ATx
   Telecom Systems Inc. (ATx) acquired in June 1996 and Arcodan A/S acquired in
   February 1997, and other miscellaneous items more than offset cost
   reductions from internal processes and systems improvements. ATx was merged
   into the Company on June 26, 1998.
 
RESEARCH AND DEVELOPMENT EXPENSES were $111.5 million in 1998. Research and
   development efforts in 1998 were focused on the development of two-way,
   real-time interactive digital networks and set-tops and related software and
   the Prisma(TM) Digital Transport product and enhancements to the 8600x set-
   tops to include features such as e-mail over television and Web browsing.
   The Company previously announced that it planned to have production
   quantities of the Prisma Digital Transport product available in the first
   quarter of fiscal 1999, but the availability of such production quantities
   will be delayed until the second quarter of fiscal 1999. The Company
   continues to invest in research and development programs to support existing
   products and new product initiatives.
 
   Certain software development costs are capitalized when incurred and are
   reported at the lower of unamortized cost or net realizable value.
   Capitalization of software development costs begins upon the establishment
   of technological feasibility. The establishment of technological feasibility
   and the ongoing assessment of recoverability of capitalized software
   development costs requires considerable judgment by management with respect
   to certain external factors, including, but not limited to, anticipated
   future revenues, estimated economic life and changes in software and
   hardware technologies.
 
   The Company capitalized $2.2 million and $2.0 million of software
   development costs in 1998 and 1997, respectively. Capitalization will cease
   when the products are available for general release to customers. Software
   development costs were not material and, therefore, were not capitalized in
   1996.
 
   The Company periodically allocates engineering resources from research and
   development efforts for specific customer orders. The revenue from these
   orders will be recognized in future periods and, accordingly,
 
                                       19
<PAGE>
 
MANAGEMENT'S DISCUSSION OF CONSOLIDATED STATEMENT OF EARNINGS (CONTINUED)
 
   the related costs have been capitalized as inventory. At June 26, 1998 and
   June 27, 1997, the Company had capitalized $11.2 million and $6.0 million,
   respectively, of such non-recurring engineering costs. During 1998, the
   Company recognized revenue on certain of these orders and, accordingly,
   charged $1.3 million to cost of sales. No such revenue was recognized in
   1997. There were no material non-recurring engineering costs capitalized at
   June 28, 1996.
 
   The Company periodically evaluates the strategic direction of the Company
   including an assessment of the markets the Company serves and alternative
   methods of generating revenues from its investments in research and
   development programs, such as licensing of software and hardware
   technology.
 
   Research and development expenses of $114.0 million in 1997 increased $19.0
   million over 1996, reflecting the Company's investment in research and
   development programs to support existing products and new product
   initiatives such as high speed cable data modems, cable telephony products,
   interactive set-tops and home automation products for the utility industry.
   In fiscal 1998, the Company discontinued its research and development
   efforts related to cable telephony products and a stand alone two-way RF
   modem because the markets for cable telephony products and two-way stand
   alone modems had not developed as quickly as the Company previously
   anticipated. A two-way modem solution is currently included in one of the
   Company's digital set-top product offerings.
 
RESTRUCTURING CHARGES of $23.4 million were recorded in the fourth quarter of
   fiscal 1998. The charges include $10.2 million and $3.2 million for fixed
   assets to be abandoned and expenses related to the cancellation of leases,
   respectively, as a result of the consolidation of operations, $5.2 million
   for severance and out placement costs, and $4.8 million for the impairment
   of certain assets and other miscellaneous expenses.
 
PURCHASED IN-PROCESS TECHNOLOGY was $14.6 million in 1996. In connection with
   the acquisition of ATx on June 28, 1996, the Company recorded a pre-tax
   charge of $14.6 million for purchased in-process technology which had not
   yet reached technological feasibility and had no alternative future use.
 
INTEREST EXPENSE was $0.5 million, $0.5 million, and $0.7 million in 1998,
   1997, and 1996, respectively. The year-to-year decrease in 1997 as compared
   to 1996 reflects lower average working capital borrowings by foreign
   subsidiaries.
 
INTEREST INCOME was $6.0 million, an increase of $2.0 million over the prior
   year, reflecting higher average cash balances in fiscal 1998.
 
OTHER INCOME of $79.9 million in 1998 included a $93.8 million net gain from
   the mark-to-market adjustment of marketable securities of which $94.0
   million related to the Company's investment in Broadcom Corporation, a $9.1
   million gain from the sale of certain assets of the interdiction business,
   a loss of $9.0 million from the discontinuance of research and development
   efforts related to the Company's CoAxiom(R) telephony products, $6.2
   million for estimated losses on the resale of used equipment, $5.5 million
   for expenses and the potential settlement of environmental issues and other
   miscellaneous items.
 
   During the quarter ended March 27, 1998, the Company sold the inventory,
   manufacturing assets and intellectual property of the interdiction business
   to Blonder Tongue Laboratories, Inc. (Blonder Tongue) for $19.0 million in
   cash, Blonder Tongue stock valued at $1.0 million and an option to acquire
   additional shares of Blonder Tongue stock. The Company recorded a pre-tax
   gain of $9.1 million related to this sale. At June 26, 1998, the Company
   had a reserve of approximately $5.5 million for research and development
   commitments, transition services, potential post-closing sales price
   adjustments and other miscellaneous expenses related to the sale.

MANAGEMENT'S DISCUSSION OF CONSOLIDATED STATEMENT OF EARNINGS (CONTINUED)
 
 
   During fiscal 1997, the Company, with consent of its product development
   partner, Siemens, decided to decrease its research and development efforts
   related to CoAxiom telephony products because the markets for these
   products had not developed as quickly as the company previously
   anticipated. During the quarter ended March 27, 1998, the Company decided
   to discontinue its efforts to develop CoAxiom systems and recorded a pre-
   tax charge of approximately $9.0 million. The charge included reserves for
   the disposal of inventory and fixed assets which were associated with the
   development of CoAxiom systems, research and development costs incurred
   during fiscal 1998 and other miscellaneous expenses. Although the Company
   discontinued development of CoAxiom telephony products, the Company will
   continue to develop applications and technology for telephony on cable
   using IP telephony which will be used in the Company's networks and
   Explorer 2000 digital interactive set-tops.
 
   During the quarter ended March 28, 1997, the Company decided to dispose of
   two business units, microwave and mobile, because these businesses were not
   aligned with the Company's core business strategies and recorded a charge
   of $5.5 million to adjust the carrying amount of the net assets held for
   sale to net realizable value and to provide for estimated indemnifications
   to the purchaser, severance, closing costs and other miscellaneous expenses
   related to the sale. During the ordinary course of business, the Company
   encounters certain risks and uncertainties related to the satisfactory
   performance under contracts which it evaluates periodically and provides
   reserves, if appropriate. Accordingly, the estimated loss on the sale of
   the microwave and mobile businesses was computed on the basis that the
   Company would sell the businesses at an amount that would allow the
   purchaser, with reasonable assurance, to complete the contracts at a
   reasonable margin.
 
   During the quarter ended December 26, 1997, the Company sold the majority
   of the net assets of the microwave business unit for $8.1 million of cash.
   No gain or loss was recognized on the transaction.
 
   After recording the $5.5 million charge discussed above, at June 26, 1998,
   the Company had a remaining reserve of approximately $4.8 million to adjust
   the carrying amount of the net assets of the mobile business unit, which
   has been discontinued, and to provide for estimated indemnifications to the
   purchaser of the microwave business unit, potential losses on contracts of
   the microwave business which were retained by the Company, severance,
   closing costs and other miscellaneous expenses related to the sale of the
   microwave business unit.
 
   Other income of $1.5 million in 1997 included a gain of $5.6 million from
   the sale of land and a building in San Diego County, California not
   required for current operations, the results of foreign currency
   transactions and partnership activities and net gains from rental income
   and other miscellaneous items.
 
   Other expense in 1996 included a charge of $28.7 million, related to an
   arbitration panel's decision in a proceeding with StarSight Telecast, Inc.
   (StarSight), for damages, legal and arbitration expenses and other
   expenses, including incremental costs to independently develop an
   electronic program guide. In April 1997, the Company and StarSight entered
   into a License and Settlement Agreement which resolved all outstanding
   disputes and provided for the cross-licensing of technologies.
 
THE PROVISION FOR INCOME TAXES was 30 percent of pre-tax earnings in 1998 and
   32 percent of pre-tax earnings in 1997 and 1996. The lower effective income
   tax rate in fiscal 1998 as compared to fiscal 1997 and 1996, is due to
   benefits from the Company's foreign sales corporation (FSC) and a decrease
   in foreign earnings taxed at a higher rate. Details of the provision for
   income taxes are discussed in Note 11.
 
GAIN ON SALE OF DISCONTINUED OPERATIONS was $3.4 million in 1997 compared to
   losses of

MANAGEMENT'S DISCUSSION OF CONSOLIDATED STATEMENT OF EARNINGS (CONTINUED)
 
   $13.2 million in 1996. Losses in 1996 included losses from discontinued
   operations of $1.0 million, net of a tax benefit of $0.5 million, and a
   one-time, after-tax charge of $12.2 million, net of a tax benefit of $5.7
   million, for the estimated loss on the sale of discontinued operations
   which was recorded in the quarter ended September 29, 1995, when the
   Company decided to discontinue its defense-related businesses in San Diego,
   California. Details of the discontinued operations are discussed in Note 6.
 
NET EARNINGS of $80.8 million in 1998 included after-tax restructuring and
   other one-time charges of $53.4 million and an after-tax net gain of $65.6
   million from the mark-to-market adjustment of marketable securities.
 
   In 1997, net earnings of $64.0 million, which included an after-tax gain of
   $3.4 million from the sale of discontinued operations, compared to a net
   loss of $6.0 million in 1996. The net loss in 1996 included after-tax
   charges of $9.9 million for purchased in-process technology, $19.5 million
   for damages, legal and arbitration expenses and $13.2 million from
   discontinued operations.
 
EARNINGS PER SHARE of $1.02 in 1998 compares with earnings per share of $0.82
   in 1997 and with a loss per share of $0.08 in 1996. Diluted shares
   outstanding increased slightly to 80.0 million in 1998 from 78.4 million in
   1997 and 76.7 million in 1996.
 
YEAR 2000 issues are being addressed by the Company. The Company, like most
   other major companies, is currently addressing a universal problem commonly
   referred to as "Year 2000 Compliance," which relates to the ability of
   computer programs and systems to properly recognize and process date
   sensitive information before and after January 1, 2000. The following
   discussion is based on information currently available to the Company.
 
   The Company has analyzed and continues to analyze its internal information
   technology ("IT") systems ("IT systems") to identify any computer programs
   that are not Year 2000 compliant and implement any changes required to make
   such systems Year 2000 compliant. The Company believes that its critical IT
   systems currently are capable of functioning without substantial Year 2000
   Compliance problems. Of the non-critical, but important, IT systems that
   are not currently Year 2000 Compliant, the Company believes such IT systems
   will be Year 2000 capable in a time frame that will avoid any material
   adverse effect on the Company. Also, the Company does not believe that the
   expenditures related to replacing or upgrading any of its IT systems to
   make them Year 2000 compliant will have a material adverse effect on the
   financial condition of the Company. The Company has identified only two IT
   systems (E-mail and electronic calendar) that must be replaced due to Year
   2000 concerns, and the Company already had plans to replace these IT system
   with one system providing increased functionality.
 
   The Company has evaluated its critical equipment and critical systems that
   contain embedded software, such as microcontrollers ("Non-IT systems"), and
   the Company believes that all of its critical Non-IT systems are capable of
   functioning without substantial Year 2000 Compliance problems.
 
   The Company plans to test its IT systems and Non-IT systems, commencing in
   the first calendar quarter of 1999.
 
   Certain products currently sold by the Company contain computer programs
   that perform date functions or date calculations. The Company has evaluated
   most of its products and is continuing to evaluate its other products, and,
   based on its investigation to date, the Company believes that the products
   it currently sells (except the System Manager product currently being sold
   with the recently-developed System Release 4.5 software) are Year 2000
   compliant, provided that they have been upgraded to include all recommended
   engineering changes. However, the Company's products are often used by its
   customers in systems that contain third party products or products supplied
   by the
 
                                      22
<PAGE>
 
MANAGEMENT'S DISCUSSION OF CONSOLIDATED STATEMENT OF EARNINGS (CONTINUED)
 
   Company in prior years, such as the System Manager products. Therefore,
   even though the Company's current products may be Year 2000 compliant, the
   failure of such third party products or historical Company-supplied
   products to be Year 2000 compliant, or to properly interface with the
   Company's current products, may result in a system failure. Certain
   products that the Company no longer offers for sale are not Year 2000
   compliant, and the Company has no plans to upgrade them. However, the
   Company does have a plan for helping its customers upgrade their System
   Manager products and related components to System Release 4.6 software
   which is currently in the final stages of development. Such System Release
   4.6 software is expected to remedy the Year 2000 problems of System Manager
   products historically sold by the Company to its customers. Because some
   customers may be using obsolete versions of the System Manager products,
   they may also need to purchase equipment to solve their Year 2000 problems.
   A customer's failure to upgrade its System Manager products to System
   Release 4.6 software may result in such customer having critical Year 2000
   problems. Under certain limited circumstances, the Company may incur
   expense to remedy such customer's critical Year 2000 failure.
 
   The Company is investigating each of its significant vendors, suppliers,
   financial service organizations, service providers and customers to confirm
   that the Company's operations will not be materially adversely affected by
   the failure of any such third party to have Year 2000 compliant computer
   programs. Regardless of the responses that the Company receives from such
   third parties, the Company is establishing contingency plans to reduce the
   Company's exposure resulting from the non-compliance of third parties.
   First, the Company plans to build inventories of critical and/or important
   components prior to January 1, 2000, and thereby decrease the Company's
   dependence on suppliers that are not Year 2000 compliant. Second, the
   Company plans to send hard copies of "Schedules of Ordered Products and
   Delivery Dates" to its major customers, commencing in the third calendar
   quarter of 1999. Such Schedules should enable customers to accept ordered
   products after January 1, 2000, even if their internal computer systems are
   not operating properly.
 
   The Company estimates that, through August 31, 1998, it has spent $200,000
   to remediate Year 2000 issues in its IT systems, and the Company estimates
   that it will spend an additional $500,000 to remediate Year 2000 issues in
   its IT systems. Additionally, the Company is accelerating into fiscal 1999
   the planned replacement of its E-mail software and electronic calendar
   software because such software has Year 2000 problems. The cost of the
   replacement software, including installation and training related thereto,
   is estimated to be $1.8 million. For the development and deployment of
   System Release 4.6 software to remedy Year 2000 problems of System Manager
   products sold by the Company, the Company has spent, through August 30,
   1998, $1,238,000 and estimates it will spend an additional $1,729,000 to
   complete such software development and deployment. All of such expenditures
   are included in the budgets of the various departments of the Company
   tasked with various aspects of the Year 2000 project. No IT projects have
   been deferred due to IT's Year 2000 efforts.
 
   The Company has approached the Year 2000 project in phases. Phase I of the
   project involved identification of all software used or sold by the
   Company, identification of all significant vendors, and establishment of a
   senior management committee (composed of the General Counsel, the Chief
   Financial Officer and the Chairman of the Corporate Operating Committee) to
   oversee the project. Phase I was completed in the second calendar quarter
   of 1998. Phase II of the project involves (a) evaluation of each
   significant vendor and evaluation of major customers through letters and
   questionnaires (b) communication with customers concerning any products
   currently or recently sold by the Company that have Year 2000 issues, and
   (c) evaluating the Company's most reasonably likely worst case Year 2000
                                      23
<PAGE>
 
MANAGEMENT'S DISCUSSION OF CONSOLIDATED STATEMENT OF EARNINGS (CONTINUED)
 
   scenarios and contingency planning related thereto. Phase II is in process
   and many of the tasks described in subparagraphs (b) and (c) above have
   been completed; Phase II is expected to be completed in the fourth calendar
   quarter of 1998. Phase III involves testing of the Company's IT systems and
   Non-IT systems to confirm Year 2000 compliance and/or discover any
   overlooked Year 2000 problems. Phase III should be completed in the first
   calendar quarter of 1999. Last, Phase IV involves implementation of the
   Company's contingency plans. Such plans are expected to be implemented in
   the third calendar quarter of 1999.
 
   The Company does not currently believe that any of the foregoing will have
   a material adverse effect on its financial condition or its results of
   operations. However, the process of evaluating the Company's products and
   third party products and systems is ongoing. Although not expected,
   failures of critical suppliers, critical customers, critical IT systems,
   critical Non-IT systems, or products sold by the Company (including any
   delay in the deployment of System Releases 4.5 and 4.6) could have a
   material adverse effect on the Company's financial condition or results of
   operations. As widely publicized, Year 2000 Compliance has many issues and
   aspects, not all of which the Company is able to accurately forecast or
   predict. There is no way to assure that Year 2000 Compliance will not have
   adverse effects on the Company, some of which could be material.
 
   Many of the Company's statements related to Year 2000 are forward-looking
   statements and actual results could differ materially from those
   anticipated above. The Company is relying on the investigations and
   statements of many employees, consultants and third parties in making the
   above forward-looking statements and such investigations or statements may
   not be accurate. For further risks and uncertainties related to these
   forward-looking statements, see Exhibit 99 to this Form 10-K.

MANAGEMENT'S DISCUSSION OF CONSOLIDATED STATEMENT OF CASH FLOWS
 
The Statement of Cash Flows summarizes the main sources of Scientific-
   Atlanta's cash and its uses. These flows of cash provided or used are
   summarized by the Company's operating activities, investing activities and
   financing activities.
 
CASH AND CASH EQUIVALENTS at the end of 1998 were $175.4 million, up $68.2
   million from the end of 1997 due to improved earnings, working capital
   management, and proceeds from the sale of the interdiction and microwave
   businesses and the issuance of common stock.
 
   The Company has a $300 million senior credit facility available that
   provides for unsecured borrowings up to $150 million which expires May 1999
   and up to $150 million which expires May 2003. There were no outstanding
   borrowings under this facility at June 26, 1998 or June 27, 1997. The
   Company believes that funds generated from operations, existing cash
   balances and its available senior credit facility will be sufficient to
   support growth and planned expansion of manufacturing capacity.
 
   During the first quarter of fiscal 1998, the Company secured a $38.0
   million commitment under a long-term operating lease for the consolidation
   of certain operations and future expansion. The initial lease term will be
   seven years with the option to extend the lease for an additional 15 years
   in 5 year increments.
 
CASH PROVIDED BY OPERATING ACTIVITIES was $80.3 million for 1998, compared to
   $125.1 million for 1997. Cash provided by earnings and reductions in
   inventory levels were offset partially by increases in accounts receivable
   as compared to the prior year. See Management's Discussion of the Statement
   of Financial Position for details of this performance.
 
   In 1997, cash provided by earnings, accounts receivable collections and
   reductions in inventory levels was partially offset by decreases in
   payables and other liabilities and increases in other assets.
 
CASH USED BY INVESTING ACTIVITIES of $14.8 million in 1998 included
   expenditures for equipment, expansion of manufacturing capacity, primarily
   in Juarez, Mexico, and other investing activities. Sources of cash included
   proceeds from the sales of the interdiction and microwave businesses. See
   Note 2 for additional discussion of investing activities.
 
   Cash used by investing activities in 1997 included expenditures for
   equipment, the expansion of manufacturing capacity, the acquisition of
   Arcodan and other investing activities. Sources of cash from investing
   activities included proceeds from the sale of defense-related businesses
   discontinued in 1996 and the sale of land and a building not required for
   current operations.
 
   In 1996, cash used by investing activities included expenditures for
   equipment, expansion of manufacturing capacity, the purchase of land for
   future expansion, the acquisition of ATx and other investing activities.
 
CASH PROVIDED BY FINANCING ACTIVITIES was $2.8 million in 1998. Financing
   activities included the repurchase of 500,000 shares of the Company's
   common stock for $7.5 million, dividend payments of $4.7 million and net
   debt payments of $0.9 million. The Company reissues these shares under the
   Company's stock option plans, 401(k) plan, employee stock purchase plan and
   other stock-based employee compensation arrangements. The issuance of stock
   pursuant to these plans generated cash of $16.0 million.
 
   Financing activities in 1997 included dividend payments of $4.6 million,
   the repurchase of 225,000 shares of the Company's common stock for $3.0
   million and net debt payments of $2.0 million. The issuance of stock
   pursuant to stock option and employee benefit plans generated cash of $6.6
   million.
 
   The repurchase of 1,010,000 shares of the Company's common stock for $12.4
   million and dividend payments of $4.6 million exceeded cash generated from
   the issuance of stock of $4.3 million in 1996.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(Dollars in thousands, except per share data)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
- -------------------------------------------------------------------------------
 
BUSINESS
Scientific-Atlanta, Inc. (the "Company") provides its customers with the
products and services they need to develop the advanced communications
networks that deliver voice, data and video. The Company's products connect
information generators with information users via broadband terrestrial and
satellite networks, and include applications for the converging cable,
telephone, and data networks.
 
The Company operates primarily in one business segment, Communications,
providing communications networks to a range of customers for a variety of
applications, and providing network management and systems integration for
those networks. This segment represents over 90 percent of consolidated sales,
operating profit and identifiable assets.
 
The Company's products are sold primarily through its own sales personnel who
work out of offices in Norcross and other metropolitan areas in the United
States. Certain products are also marketed in the United States through
independent sales representatives and distributors. In addition to direct
sales by the Company, sales in foreign countries are made through wholly-owned
subsidiaries and branch offices, as well as through independent distributors
and independent sales representatives.
 
The materials and supplies purchased by the Company are standard electronic
components, such as integrated circuits, wire, circuit boards, transistors,
capacitors and resistors, all of which are produced by a number of
manufacturers. Matsushita Electronic Components Co., Ltd. and its affiliates
manufacture analog set-tops for the Company and are a primary supplier of
those set-tops. Cablevision Electronics Co., Ltd. and Zinwell Corporation,
Taiwanese companies, are primary suppliers of taps for the Company. The
Company also purchases aluminum and steel, including castings and semi-
fabricated items, produced by a variety of sources. The Company's primary
supplier of die castings for its RF distribution products is Premiere Die
Casting, Inc. Additionally, Motorola, Inc., Broadcom Corporation and SGS-
Thomson Microelectronics, Inc. are three of the Company's primary suppliers of
a variety of semi-conductor products, which are used as components in an array
of the Company's products, including its set-tops. The Company considers its
sources of supply to be adequate and is not dependent upon any single
supplier, except for Matsushita Electronic Components Co., Ltd. (and
affiliates), Cablevision Electronics Co., Ltd., Zinwell Corporation, Premiere
Die Casting, Inc., Motorola, Inc., Broadcom Corporation and SGS-Thomson
Microelectronics, Inc., for any significant portion of the materials used in
the products it manufactures or for the products it sells.
 
FISCAL YEAR-END
The Company's fiscal year ends on the Friday closest to June 30 of each year.
Fiscal year ends are as follows:
 
<TABLE>
     <S>    <C>
     1998:  June 26, 1998
     1997:  June 27, 1997
     1996:  June 28, 1996
</TABLE>
 
CONSOLIDATION
The accompanying consolidated financial statements include the accounts of the
Company and all subsidiaries after elimination of all material intercompany
accounts and transactions.
 
USE OF ESTIMATES
The preparation of the accompanying consolidated 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 liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting periods. Actual results could differ from those estimates. The
estimates made by management primarily relate to receivable and inventory
reserves, estimated costs to complete long-term contracts and certain accrued
liabilities, principally relating to warranty and service provisions and
restructuring reserves, compensation, claims, litigation and taxes.
 
FOREIGN CURRENCY TRANSLATION
The financial statements of certain foreign operations are translated into
U.S. dollars at current
                                      29
<PAGE>
 
exchange rates. Resulting translation adjustments are accumulated as a
component of stockholders' equity and excluded from net earnings. Foreign
currency transaction gains and losses are included in cost of sales and other
income.
 
FOREIGN EXCHANGE CONTRACTS
The Company enters into foreign exchange forward contracts to hedge certain
firm commitments and assets denominated in currencies other than the U.S.
dollar, primarily Japanese yen. These contracts are for periods consistent with
the exposure being hedged and generally have maturities of one year or less. To
qualify as a hedge, the item to be hedged must expose the Company to inventory
pricing or asset devaluation risk and the related contract must reduce that
exposure and be designated by the Company as a hedge. Gains and losses on
foreign exchange forward contracts, including cost of the contracts, are
deferred and recognized in income in the same period as the hedged
transactions. The Company's foreign exchange forward contracts do not subject
the Company's results of operations to risk due to exchange rate fluctuations
because gains and losses on these contracts generally offset losses and gains
on the exposure being hedged. The Company does not enter into any foreign
exchange forward contracts for speculative trading purposes. If a foreign
exchange forward contract did not meet the criteria for a hedge, the Company
would recognize unrealized gains and losses as they occur.
 
Firmly committed purchase exposure and related derivative contracts for fiscal
1999 are as follows:

</TABLE>
 
The Company has no derivative exposure beyond fiscal 1999.
 
METHOD OF RECORDING CONTRACT PROFITS
Revenues from progress-billed contracts are primarily recorded using the
percentage-of-completion method based on contract costs incurred to date.
Losses, if any, are recorded when determinable. Costs incurred and accrued
profits not billed on these contracts are included in receivables. The
receivables from commercial customers and government agencies were $9,138 at
June 26, 1998 and $22,515 at June 27, 1997. It is anticipated that
substantially all such amounts will be collected within one year.
 
RESEARCH AND DEVELOPMENT EXPENDITURES
Certain software development costs are capitalized when incurred and are
reported at the lower of unamortized cost or net realizable value.
Capitalization of software development costs begins upon the establishment of
technological feasibility. The establishment of technological feasibility and
the ongoing assessment of recoverability of capitalized software development
costs require considerable judgment by management with respect to certain
external factors, including, but not limited to, anticipated future revenues,
estimated economic life and changes in software and hardware technologies.
 
The Company capitalized $2,181 and $2,022 of software development costs in 1998
and 1997, respectively. Capitalization will cease when the products are
available for general release to customers. Software development costs were not
material and, therefore, were not capitalized in 1996.
 
The Company periodically allocates engineering resources from research and
development efforts for specific customer orders. The revenue from these orders
will be recognized in future periods and, accordingly, the related costs have
been inventoried. At June 26, 1998 and June 27, 1997, the Company had
capitalized $11,188 and $6,047 of such non-recurring engineering costs. During
1998, the Company recognized revenue on certain of these orders and,
accordingly, charged $1,341 to cost of sales. No such revenue was recognized in
1997. There were no material non-recurring engineering costs capitalized at
June 28, 1996.
 
DEPRECIATION, MAINTENANCE AND REPAIRS
Depreciation is provided using principally the straight-line method over the
estimated useful lives of the assets. Maintenance and repairs are charged to
expense as incurred. Renewals and betterments are capitalized. The cost and
accumulated depreciation of property retired or otherwise disposed of are
removed from the respective accounts, and the gains
                                       30
<PAGE>
 
or losses thereon are included in the consolidated statement of earnings.
 
WARRANTY COSTS
The Company accrues warranty costs at the time of sale. Expenses related to
unusual product warranty problems and product defects are recorded in the
period the problem is identified.
 
EARNINGS PER SHARE
Basic earnings per share were computed based on the weighted average number of
shares of common stock outstanding. Diluted earnings per share were computed
based on the weighted average number of diluted shares of common stock
outstanding.
 
CASH AND CASH EQUIVALENTS
For purposes of the statement of cash flows, the Company considers all debt
instruments purchased with a maturity of three months or less to be cash
equivalents.
 
MARKETABLE SECURITIES
Marketable securities consist of investments in common stock and are stated at
market value. All marketable securities are defined as trading securities under
the provisions of Statement of Financial Accounting Standards (SFAS) No. 115
and unrealized holding gains and losses are reflected in earnings.
 
INVENTORIES
Inventories are stated at the lower of cost (first-in, first-out) or market.
Cost includes materials, direct labor, and manufacturing overhead. Market is
defined principally as net realizable value. Inventories include purchased and
manufactured components in various stages of assembly as presented in the
following table:

COST IN EXCESS OF NET ASSETS ACQUIRED
Cost in excess of net assets of businesses acquired is amortized on a straight-
line basis over seventeen years. The Company periodically evaluates the
carrying values assigned to costs in excess of net assets acquired and other
intangible assets.
 
FINANCIAL PRESENTATION
Certain prior year amounts have been restated to reflect the discontinuance in
1996 of defense related businesses. See Note 6.
 
2. INVESTMENTS AND ACQUISITIONS
- --------------------------------------------------------------------------------
 
On February 28, 1997, the Company acquired 100 percent of the outstanding stock
of Arcodan A/S (Arcodan) for $15,000 in cash. Arcodan is a Danish manufacturer
of advanced analog and digital headend systems, opto-electronics and RF
distribution equipment. The acquisition was accounted for as a purchase and,
accordingly, the acquired assets and liabilities were recorded at their
estimated fair value at the date of acquisition. The purchase price has been
allocated to the assets acquired and liabilities assumed, including $5,781 to
cost in excess of net assets acquired.
 
On June 28, 1996, the Company acquired 100 percent of the outstanding stock of
ATx Telecom Systems, Inc. (ATx) for $24,336 in cash and a subsequent payment of
$152. ATx was a supplier of fiber optic products for hybrid fiber/coax
networks. The acquisition was accounted for as a purchase and, accordingly, the
acquired assets and liabilities were recorded at their estimated fair value at
the date of acquisition. The purchase price of $24,336 has been allocated to
the assets acquired and liabilities assumed. Approximately $14,583 of the total
purchase price represented the value of ATx's in-process technology. Since
technological feasibility had not yet been achieved and there was no
alternative future use for the technology being developed, the amounts
allocated to the in-process technology were expensed concurrent with the
purchase.
 
During 1996, the Company also acquired a minority interest in Wink
Communications, Inc. (Wink), an enabling software developer, for $2,400. The
Company invested an additional $500 in Wink during fiscal 1997.
 
3. SALES
- --------------------------------------------------------------------------------
 
Sales to Time Warner, Inc. and affiliates and MediaOne and affiliates were each
11 percent of total sales in 1998. Sales to Time Warner, Inc. and affiliates
were 11 percent of total sales in 1997. Sales to any one customer were less
than 10 percent
 
                                       31
<PAGE>
 
of total sales in 1996. Export sales accounted for 32 percent of total sales in
1998, 37 percent in 1997 and 36 percent in 1996. Sales to Europe were 14
percent, 16 percent and 12 percent of total sales in 1998, 1997 and 1996,
respectively. Sales of set-top terminals constituted approximately 34 percent
of the Company's total sales in 1998, and approximately 30 percent and 27
percent of such sales in 1997 and 1996, respectively. Sales of RF (radio
frequency) products were approximately 18 percent of the Company's total sales
in 1998, and approximately 19 percent and 21 percent of such sales in 1997 and
1996, respectively. Foreign subsidiary sales were not material for any of the
three fiscal years presented.
 
4. RESTRUCTURING CHARGES
- --------------------------------------------------------------------------------
 
During 1998, the Company announced that it would implement a restructuring and
consolidation of worldwide manufacturing operations for reduced cost, improved
efficiency and better customer service. Production of the RF amplifier is
expected to be transferred from Norcross, Georgia to the Company's high volume,
low cost manufacturing facility in Juarez, Mexico by October 1998. The Norcross
manufacturing facility is expected to focus on medium-to-low-volume products
requiring close engineering support. The production of cable headend equipment
is planned to be consolidated in Norcross from Vancouver, British Columbia.
This move is designed to improve efficiency and more effectively manage the
transition of analog to digital headend products. The Melbourne, Florida
satellite services Network Operations Center (NOC) and research and development
facility is scheduled to be relocated to Norcross. The Company's European
headquarters have been moved from London, England to Frankfurt, Germany to
better address market opportunities in continental Europe. The Far East
regional headquarters have been transferred from Hong Kong to Singapore. The
Company's Satellite Networks and Communications and Tracking Systems business
units are being combined to capitalize on the combined resources provided by
concentrated capabilities in networks, research and development, marketing and
sales, and customer program management and services.
 
The Company recorded restructuring charges of $23,412 which included $10,217
and $3,200 for assets to be abandoned and expenses related to the cancellation
of leases, respectively, as a result of the consolidation of operations, $5,173
for severance and outplacement costs for approximately 500 employees primarily
in manufacturing positions and $4,822 for the impairment of certain assets and
other miscellaneous expenses. The Company expects to complete the restructuring
and consolidation of operations within one year.
 
5. OTHER (INCOME) EXPENSE
- --------------------------------------------------------------------------------
 
Other income of $79,863 in 1998 included a gain of $94,000 from the adjustment
of the Company's investment in Broadcom Corporation to market value, a gain of
$9,080 from the sale of certain assets of the interdiction business, a loss of
$9,000 from the discontinuance of research and development efforts related to
the Company's CoAxiom telephony products, a loss of $6,250 for estimated losses
on the resale of equipment the Company is contractually obligated to supply,
$5,500 for expenses and the potential settlement of environmental issues and
other miscellaneous items.
 
During 1998, the Company sold the inventory, manufacturing assets and
intellectual property of the interdiction business to Blonder Tongue
Laboratories, Inc. (Blonder Tongue) for $19,000 in cash, Blonder Tongue stock
valued at $1,000 and an option to acquire additional shares of Blonder Tongue
stock, and the Company recorded a pre-tax gain of $9,080. At June 26, 1998, the
Company had a reserve of approximately $5,500 for research and development
commitments, transition services, potential post-closing sales price
adjustments and other miscellaneous expenses related to the sale.
 
During fiscal 1997 the Company decided to decrease its research and development
efforts related to CoAxiom telephony products because the markets for these
products had not developed as quickly as the Company previously anticipated.
During fiscal 1998, the Company decided to discontinue its efforts to develop
CoAxiom systems and recorded a pre-tax charge of approximately $9,000. The
charge included reserves for the disposal of inventory and fixed assets which
were associated with the development of CoAxiom systems, research and
development costs incurred during fiscal 1998 and other miscellaneous expenses.
Although the Company discontinued development of CoAxiom telephony products,
the Company will continue to
                                       32
<PAGE>
 
develop applications and technology for telephony on cable using IP (Internet
protocol) telephony which will be used in the Company's networks and Explorer
2000 digital interactive set-tops.
 
During the quarter ended March 28, 1997, the Company decided to dispose of two
business units, microwave and mobile, because these businesses were not aligned
with the Company's core business strategies. The Company recorded a charge of
$5,526 during the quarter ended March 28, 1997 to adjust the carrying amount of
the net assets held for sale to net realizable value and to provide for
estimated indemnifications to the purchaser, severance, closing costs and other
miscellaneous expenses related to the sale. During the ordinary course of
business, the Company encounters certain risks and uncertainties related to the
satisfactory performance under contracts which it evaluates periodically and
provides reserves, if appropriate. Accordingly, the estimated loss on the sale
of the microwave and mobile businesses was computed on the basis that the
Company would sell the businesses at an amount that would allow the purchaser,
with reasonable assurance, to complete the contracts at a reasonable margin.
 
During 1998, the Company sold the majority of the net assets of the microwave
business unit for $8,059 of cash. No gain or loss was recognized on the
transaction.
 
At June 26, 1998, the Company had a reserve of approximately $4,800 to adjust
the carrying amount of the net assets of the mobile business unit, which has
been discontinued, and to provide for estimated indemnifications to the
purchaser of the microwave business unit, potential losses on contracts of the
microwave business which were retained by the Company, severance, closing costs
and other miscellaneous expenses related to the sale of the microwave business
unit.
 
Other income of $1,513 in 1997 included a gain from the sale of land and a
building in San Diego County, California not required for current operations,
the results of foreign currency transactions and partnership activities, and
net gains from rental income and other miscellaneous items.
 
Other expense in 1996 included a charge of $28,700 related to an arbitration
panel's decision in a proceeding with StarSight Telecast, Inc. (StarSight), for
damages, legal and arbitration expenses and other expenses, including
incremental costs to independently develop an electronic program guide.
 
In April 1997, the Company and StarSight entered into a License and Settlement
Agreement which resolved all outstanding disputes and provided for the cross-
licensing of technologies.
 
6. DISCONTINUED OPERATIONS
- --------------------------------------------------------------------------------
 
During the quarter ended September 29, 1995, the Company decided to discontinue
its defense-related businesses in San Diego, California because these
businesses were not aligned with the Company's core business strategies. A one-
time charge of $12,172, net of a tax benefit of $5,728 for the estimated loss
on the sale of discontinued operations was recorded in the quarter ended
September 29, 1995.
 
On August 14, 1996, the Company completed the sale of its defense-related
businesses to Global Associates, Ltd. (Global) for cash of $13,274 and secured
and unsecured notes aggregating approximately $5,000. The net realizable value
of the assets of the defense-related businesses and settlement of issues
related to the pricing of the unexercised options with a prime contractor were
more favorable than the Company had anticipated when it decided to exit these
businesses; accordingly the Company recognized a pre-tax gain of $5,000 from
these transactions in the first quarter of 1997. Losses from the defense-
related businesses, while they were accounted for as discontinued operations of
$2,482, net of a tax benefit of $1,168, approximated the amount included in the
$12,172 one-time after-tax charge for the estimated loss on the sale of
discontinued operations. At June 26, 1998, the Company had a reserve of
approximately $7,100 for potential sales price adjustments, indemnifications
provided to Global, legal, severance and other miscellaneous expenses related
to the sale and the settlement with the prime contractor.
 
Global is currently in default under its promissory notes to the Company and
under promissory notes to Global's senior lenders and, in January 1998, filed a
voluntary petition for a Chapter 11 reorganization in the United States
Bankruptcy Court. Whether Global will successfully reorganize in this
bankruptcy
 
                                       33
<PAGE>
 
proceeding is not known at this time. If a satisfactory resolution of the
situation is not reached, the company believes it has adequate reserves to
cover any potential losses related to Global's default on the promissory notes
and related to any contracts of the defense-related businesses from which the
Company has not been released.
 
Sales and losses (previously accrued) from discontinued operations were as
follows:

12. RETIREMENT AND BENEFIT PLANS
- -----------------------------------
 
The Company has a defined benefit pension plan covering substantially all of
its domestic employees. The benefits are based upon the employees' years of
service, age and compensation.
 
The Company's funding policy is to contribute annually the amount expensed each
year consistent with the requirements of the federal law to the extent that
such costs are currently deductible.
 
The following table sets forth the plan's funded status and amounts recognized
in the Company's Consolidated Statement of Financial Position at year-end,
using March 31 as a measurement date for all actuarial calculations of asset
and liability values and significant actuarial assumptions:

15. COMMITMENTS, CONTINGENCIES, AND OTHER MATTERS
- --------------------------------------------------------------------------------
 
Rental expense under operating lease agreements for facilities and equipment
for 1998, 1997 and 1996 was $23,262, $17,462 and $15,347, respectively. The
Company pays taxes, insurance, and maintenance costs with respect to most
leased items. Remaining operating lease terms, including renewals, range up to
eight years. Future minimum payments at June 26, 1998, under operating leases
were $49,676. Payments under these leases for the next five years are as
follows: 1999 -- $14,392; 2000 -- $10,356; 2001 -- $7,709; 2002 -- $5,936; and
2003 -- $4,604.
 
During the first quarter of fiscal 1998, the Company secured a $38,000
commitment under a long-term operating lease for the consolidation of certain
operations and future expansion. The initial lease term will be seven years
with the option to extend the lease for an additional 15 years in 5 year
increments.
 
The Company has agreements with certain officers which include certain benefits
in the event of termination of the officers' employment as a result of a change
in control of the Company.
 
The Company is also committed under certain purchase agreements which are
intended to benefit future periods.
 
The Company is a party to various legal proceedings arising in the ordinary
course of business. In management's opinion, the outcome of these proceedings

results of operations.
 
16. COMMON STOCK AND RELATED MATTERS
- --------------------------------------------------------------------------------
 
The Company purchased 500,000 shares of its common stock at an aggregate cost
of $7,511 during fiscal 1998, 225,000 shares at an aggregate cost of $2,973
during fiscal 1997, and 1,010,000 shares at an aggregate cost of $12,411 during
1996.
 
The Company has non-qualified and incentive stock option plans to provide key
employees and directors with an increased incentive to work for the success of
the Company. Generally, the option price for stock options is the market value
at the date of grant and thus, the plans are non-compensatory. The options
expire 10 years after the dates of their respective grants.
 
The Company accounts for the stock purchase and stock option plans under APB
Opinion No. 25, which requires compensation costs to be recognized only when
the option price differs from the market price at the grant date. SFAS No. 123
allows a company to follow APB Opinion No. 25 with the following additional
disclosure that shows what the Company's net income (loss) and earnings (loss)
per share would have been using the compensation model under SFAS No. 123:

Because the SFAS No. 123 method of accounting has not been applied to options
granted prior to July 1, 1995, the resulting pro forma compensation cost may
not be representative of that to be expected in future years.

At June 26, 1998, an additional 825,533 shares were reserved under employee and
director stock option plans.
 
The Company has an employee stock purchase plan whereby the Company provides
certain purchase benefits for participating employees. At June 26, 1998, no
shares were reserved for issuance to employees under the plan. In August 1998,
the Board of Directors approved a new employee stock purchase plan to replace
the existing plan. Under the new plan, 1,000,000 shares were reserved for
issuance to employees.
 
The Company has a 401(k) plan whereby the Company matches eligible employee
contributions in Company stock, subject to certain limitations. The Company's
expense to match contributions was $6,450, $6,075 and $5,644, in 1998, 1997,
and 1996, respectively. At June 26, 1998, no shares were reserved for issuance
to employees under the plan. On August 20, 1998, the Board of Directors
reserved 3,000,000 shares for this plan.
 
The Company has a stock plan for non-employee directors which provides for 500
shares of common stock of the Company to be granted to each director annually,
which allows directors to elect to receive all or a portion of his or her
quarterly compensation from the Company in the form of shares of common stock
of the Company, and which also provides for a retirement award of 1,500 shares
of common stock of the Company. At June 26, 1998, 84,000 shares were reserved
for issuance to non-employee directors under the plan.
 
The Company issues restricted stock awards and non-qualified stock option
grants to certain officers and key employees under a long-term incentive plan.
Compensation expense for restricted stock awards was $2,670, $845, and $470, in
1998, 1997, and 1996, respectively. At June 26, 1998, 1,047,444 shares were
reserved for issuance under this plan.

At June 26, 1998, a total of 1,956,977 shares of authorized stock were reserved
for the above purposes.
 
The Company adopted a Rights Plan effective upon expiration of its previous
Shareholder Rights Plan in April 1997, and pursuant to the Plan declared a
dividend of one Right for each outstanding share of common stock. For shares
issued after such dividend, a Right attaches to each share of common stock
issued. The Right is to purchase 1/1000th share of preferred stock at an
exercise price of $118. Separate Rights certificates will be distributed and
the Rights will become exercisable if a person or group (i) acquires beneficial
ownership of 15 percent or more of the Company's common stock, (ii) makes a
tender offer to acquire 15 percent or more of the Company's common stock, or
(iii) is determined by the Board of Directors to be an "adverse person" as
defined by the Plan. If a person or a group becomes a 15 percent holder (other
than by offer for all shares approved by the Board of Directors) or is
determined by the Board of Directors to be an "adverse person", each Right will
entitle the holder thereof, other than the acquiring shareholder or adverse
person, to acquire, upon payment of the exercise price, common stock of the
Company having a value equal to twice the exercise price. If the Company
engages in a merger or other business combination in which the Company does not
survive, and which is not approved by the Board of Directors, each Right
entitles the holder to acquire common shares of the surviving company having a
market value equal to twice the exercise price. Following the occurrence of any
event described in either of the two preceding sentences, the Company is
required by the Rights Plan to reserve sufficient shares of its common stock to
permit the exercise in full of all outstanding Rights. At June 26,1998 no
shares of common stock were reserved for this purpose. The Rights may be
redeemed by the Company at a price of $0.01 per Right at any time prior to 10
days after the announcement that a party acquired 15 percent or more of the
Company's common stock or prior to the date any person or group is determined
by the Board of Directors to be an "adverse person". The Rights have no voting
power and, until exercised, no dilutive effect on earnings per share. If not
previously redeemed, the Rights will expire on April 13, 2007.
 
In connection with adoption of the new Rights Plan, the Board of Directors
designated 350,000 shares of Series A Junior Participating Preferred Stock from
the Company's 50,000,000 authorized shares of preferred stock for issuance
under for the Rights Plan. Upon issuance, each share of preferred stock is
entitled to a quarterly dividend equal to the greater of $0.01 or 1,000 times
the per share amount of all cash dividends, non-cash dividends, or other
distributions, other than dividends payable in common stock, declared on the
Company's common stock. At June 26, 1998, there were 79,085 shares of preferred
stock reserved for this purpose.

- --------------------------------------------------------------------------------
 
In February 1997, the Financial Accounting Standards Board issued Statement 128
"Earnings Per Share" superseding Accounting Principles Board Opinion No. 15,
"Earnings Per Share". The Company adopted SFAS No. 128 in fiscal 1998. Earnings

18. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
- --------------------------------------------------------------------------------
 
In June 1998, the Financial Accounting Standards Board issued Statement 133
"Accounting for Derivative Instruments and Hedging Activities" which the
Company plans to adopt in fiscal 2000. Management is still assessing the impact
of the adoption of this statement. Currently, management does not believe the
adoption of this statement will have a material impact on the Company's results
of operations or financial condition.

an incentive for Non-employee Directors to contribute their best efforts to the

percent (100%) of his or her Quarterly Compensation (in increments of 5%) in the
form of Shares pursuant to an Elective Grant made in accordance with this
Section 3(a). The election by the Non-employee Director to receive an Elective
Grant of Shares must be in writing and must be delivered to the Secretary of the
Company before the start of the fiscal quarter during which services are to be
rendered by the Non-employee Director giving rise to the Quarterly Compensation.
The election made by a Non-employee Director pursuant to this Section 3(a) shall
be in effect as to Quarterly Compensation payable for services rendered during
the fiscal quarter of the Company covered by the election. The Committee shall,
prior to the receipt by a Non-employee Director of shares under an Elective
Grant, approve the issuance of such shares by resolution; however, if the
Committee fails to adopt such an approving resolution, such shares may be issued
to the electing Non-employee Director, but such shares cannot be sold or
otherwise transferred by such Non-employee Director prior to the date which is
six (6) months after the date of such issuance of shares.

     (b)  The number of Shares to be granted to a Non-employee Director who
makes an Elective Grant shall equal (i) the amount of the Quarterly Compensation
earned during the Company's fiscal quarter subject to the Elective Grant,
divided by (ii) the Fair Market Value Per Share on the last day of such fiscal
quarter. In no event shall the Company be required to issue fractional Shares.
Any fractional Share will be rounded to the nearest whole Share.
 

                                       3
<PAGE>
 
     (c)  As soon as practicable after each Non-employee Director's Elective
Grant of Shares is determined, the Company shall cause to be issued and
delivered to such Non-employee Director a stock certificate registered in the
name of the Non-employee Director evidencing his or her Elective Grant, less any
Shares withheld by the Company pursuant to Section 8 below.

     (d)  No right to an Elective Grant and no interest therein may be assigned,
pledged, hypothecated, or otherwise transferred by a Non-employee Director
except that, in the event of the death of a Non-employee Director prior to the
issuance of a stock certificate evidencing an Elective Grant, such right to such
Elective Grant may be transferred to the Non-employee Director's designated
beneficiary or, in the absence of such designation, by will or the laws of
descent and distribution.

4.   STOCK AWARDS

     (a)  Beginning with the 1995 Annual Meeting and at the Annual Meeting every
year thereafter through and including the Annual Meeting held in 2009, every
Eligible Director shall be granted a Stock Award.

     (b)  Subject to the provisions of Section 8 hereof, as soon as practicable
after the applicable Annual Meeting, the Company shall cause to be issued and
delivered to each Eligible Director receiving a Stock Award a stock certificate
registered in the name of such Eligible Director evidencing the Stock Award,
less any Shares withheld by the Company pursuant to Section 8 below.

     (c)  Eligible Directors shall not be deemed for any purpose to be, or have
any rights as, shareholders of the Company with respect to any Stock Award until
the stock certificates are issued and then only from the date of the issuance of
such stock certificates. Appropriate adjustments shall be made for dividends or
distributions or other rights for which the record date is after an Annual
Meeting and prior to the issuance of such stock certificates.

     (d)  No right to a Stock Award and no interests therein may be assigned,
pledged, hypothecated, or otherwise transferred by an Eligible Director except
that, in the event of the death of a Non-employee Director prior to the issuance
of a stock certificate evidencing a Stock Award, such right to such Stock Award
may be transferred to the Non-employee Director's designated beneficiary or, in
the absence of such designation, by will or the laws of descent and
distribution.

5.   RETIREMENT AWARDS

     (a)  Beginning with the 1997 Annual Meeting and at the Annual Meeting every
year thereafter through and including the Annual Meeting held 2009, every
Eligible Director shall be granted a Retirement Award. Each Eligible Director
shall elect annually either (i) to defer his or her right to receive such
Retirement Award, under the Deferred Compensation Plan for Non-employee
Directors, for a minimum period of two (2) years after the date of the grant
thereof (a "Deferred Retirement Award"), or (ii) to receive such Retirement
Award as restricted stock that

                                       4
<PAGE>
 
cannot be sold, assigned or otherwise disposed of by the Eligible Director for a
period of two (2) years after the date of the grant thereof (a "Restricted
Retirement Award").

     (b)  Subject to the provisions of Section 8, as soon as practicable after
the expiration of (i) the deferral period under the Deferred Compensation Plan
for Non-employee Directors applicable to a Deferred Retirement Award, or (ii)
the restriction period under this Plan applicable to a Restricted Retirement
Award, as applicable, the Company shall cause to be issued to the pertinent
Eligible Director a stock certificate registered in the name of such Eligible
Director evidencing the Deferred Retirement Award or the Restricted Retirement
Award, as applicable.

     (c)  Eligible Directors shall not be deemed for any purpose to be, or have
any rights as, shareholders of the Company with respect to any Retirement Award
until the stock certificates are issued and then only from the date of the
issuance of such stock certificates. Appropriate adjustments shall be made for
dividends or distributions or other rights for which the record date is after an
Annual Meeting and prior to the issuance of such stock certificates.

     (d)  No right to a Retirement Award and no interests therein may be
assigned, pledged, hypothecated, or otherwise transferred by an Eligible
Director except that, in the event of the death of a Non-employee Director prior
to the issuance of a stock certificate evidencing a Retirement Award, such right
to such Retirement Award may be transferred to the Non-employee Director's
designated beneficiary or, in the absence of such designation, by will or the
laws of descent and distribution.

     (e)  During the two (2) year restriction period applicable to a Restricted
Retirement Award, Eligible Directors shall have all rights of a shareholder with
respect to the Shares granted under the Retirement Award, including the right to
vote such Shares and to receive dividends and other distributions paid with
respect to such Shares, but they shall not have the right to sell, exchange,
transfer, pledge, hypothecate or otherwise dispose of such Restricted Retirement
Award, except that such Shares may be transferred upon the death of the Eligible
Director to such of his legal representatives, heirs and legatees as may be
entitled thereto by will or the laws of intestacy.

6.   LUMP SUM DISTRIBUTIONS

     (a)  As soon as practicable after the 1997 Annual Meeting, every Eligible
Director who has elected to receive a Lump Sum Distribution, in accordance with
paragraph 3 of the Retirement Plan for Non-employee Directors, shall be granted
a Lump Sum Distribution under this Plan. Each Eligible Director shall elect to
defer his or her right to receive such Lump Sum Distribution, under the Deferred
Compensation Plan for Non-employee Directors, until not earlier than such
Eligible Director's Retirement, Death or Total Disability (as such terms are
defined in that plan).

                                       5
<PAGE>
 
     (b)  Subject to the provisions of Section 8, as soon as practicable after
the expiration of the deferral period under the Deferred Compensation Plan for
Non-employee Directors applicable to such Lump Sum Distribution for an Eligible
Director, the Company shall cause to be issued to such Eligible Director
receiving a Lump Sum Distribution a stock certificate registered in the name of
such Eligible Director evidencing the Lump Sum Distribution.

     (c)  Eligible Directors shall not be deemed for any purpose to be, or have
any rights as, shareholders of the Company with respect to any Lump Sum
Distribution until the stock certificates are issued and then only from the date
of the issuance of such stock certificates. Appropriate adjustments shall be
made for dividends or distributions or other rights for which the record date is
after an Annual Meeting and prior to the issuance of such stock certificates.

     (d)  No right to a Lump Sum Distribution and no interests therein may be
assigned, pledged, hypothecated, or otherwise transferred by an Eligible
Director except that, in the event of the death of a Non-employee Director prior
to the issuance of a stock certificate evidencing a Lump Sum Distribution, such
right to such Lump Sum Distribution may be transferred to the Non-employee
Director's designated beneficiary or, in the absence of such designation, by
will or the laws of descent and distribution.

7.   ADJUSTMENT UPON CHANGES IN CAPITALIZATION

If a reorganization, recapitalization, stock split, stock dividend, combination
of shares, merger, consolidation, rights offering, or any other change in the
corporate structure of the Company or the Shares occurs, then the number and/or
kind of shares to be awarded under the Plan shall be automatically adjusted as
required in order to prevent an unfavorable effect upon the value of the Awards
to be made under this Plan.

8.   ELECTION FOR TAX PURPOSES/TAX WITHHOLDING/DEFERRAL

     (a)  All Awards made pursuant to this Plan shall be subject to the
withholding of state and federal income taxes, FICA tax or other taxes to the
extent required by applicable law. The Company shall, before delivery of a stock
certificate evidencing an Award, require the recipient to make arrangements
satisfactory to the Company to satisfy such withholding requirement, if any. An
Eligible Director receiving an Award may satisfy such withholding requirement by
having the Company withhold Shares otherwise issuable to the Eligible Director
if such Director makes a written election to do so, which election must be
delivered to the Secretary of the Company. Each Eligible Director receiving a
Restricted Retirement Award shall have the right to make an election, under the
terms of Section 83(b) of the U.S. tax code and related regulations, whereby
such Eligible Director would treat such Restricted Retirement Award as creating
income on the date of the grant thereof, rather than on the date upon which the
restriction period expires.

     (b)  The right to receive any Shares under this Plan, at the election of
the Non-employee Director receiving an Award (without need for Committee
approval), may be deferred under the provisions of the Company's Deferred
Compensation Plan for Non-employee

                                       6
<PAGE>
 
Directors. In the event of such a deferral, the Eligible Director will not have
any rights of ownership, such as voting, selling or receipt of dividends, until
the deferral period for such Award expires.
 
9.   ADMINISTRATION

The Plan shall be administered by the Committee. The Committee shall have full
authority, consistent with the Plan, to interpret the Plan and to promulgate
such rules and regulations with respect to the Plan as it deems desirable for
the administration of the Plan. The Committee shall have authority to determine
all matters relating to the administration and granting of Awards. All
decisions, determinations and interpretations of the Committee shall be binding
upon all persons.

10.  COMPLIANCE WITH APPLICABLE LEGAL REQUIREMENTS

The Plan, the Awards, and the obligation of the Company to deliver Shares under
the Plan shall be subject to all applicable laws, regulations, and the
requirements of the exchanges on which Shares may, at the time, be listed.  In
the event that the Shares to be issued under this Plan are not registered under
the Securities Act of 1933 and/or any applicable state securities laws prior to
the delivery of such Shares, the Company may require, as a condition to the
issuance thereof, that each Eligible Director to whom such Shares are to be
issued represent and warrant in writing to the Company that the Shares are being
acquired by him or her for investment for his or her account and not for resale
or with any intent of participating directly or indirectly in any distribution
of such Shares and a legend to that effect may be placed on the stock
certificates representing such Shares.

11.  AMENDMENTS

The Committee with Board Approval may amend this Plan or any provision thereof
from time to time for the purpose of satisfying the requirements of any changes
in applicable laws or regulations or for any other purpose which at the time may
be permitted by law, provided that no amendment, except with shareholder
Approval, shall: (i) change the calculation of the Awards so as to increase the
value of the award to the Non-employee Directors; (ii) increase the frequency of
the Awards, (iii) materially increase in any other way the benefits to the Non-
employee Directors, (iv) materially modify the definitions of Non-employee
Director or Eligible Directors as defined herein, or (v) disqualify a Non-
employee Director from being a "Non-Employee Director" administrator (within the
meaning of Rule 16b-3 or any successor rule of the Securities and Exchange
Commission) of any stock-based plan of the Company. Notwithstanding the
foregoing, in no case may the Plan provisions pertaining to the amount or
determination of a Stock Award, Elective Grant, Retirement Award, or the
determination of Eligible Directors be amended more than once every six months,
other than to comport with changes in the Internal Revenue Code, the Employee

selected by the Participant on the applicable Election Form or any permitted

Commencement Date over the five, ten, or fifteen year period, based on assumed
interest earnings at the Plan Interest Rate in effect for such first year.

     6.2  Termination of Employment
          -------------------------

     Deferred benefits shall be paid to a Participant upon his or her
termination of employment, as follows:

     (a)  Upon the involuntary termination of a Participant's employment by the
Employer, if such termination is determined to be involuntary by the Plan
Committee:
 
     (1)  the Employment Termination Date shall be deemed to be the Deferred
Benefit Commencement Date applicable to each Deferred Benefit Account;
 
     (2)  the amount in each Deferred Benefit Account shall be payable to the
Participant either (i) on the Deferred Benefit Commencement Date that applies to
such Deferred Benefit Account, taking into consideration the aforesaid deemed
date (Section 6.2(a)(1)) pursuant to the method requested by the Participant in
his or her Election Form, or (ii) in the manner requested by the Participant in
his or her Election Form to apply in the event of his or her involuntary
termination by the Employer;
 
     (3)  for purposes of this Plan, termination for "good cause" of any
Participant will be construed to be and will be treated as a voluntary
termination by such a Participant, regardless of his or her age, and the
Employer will pay out to such a Participant all amounts in his or her Deferred
Benefit Accounts in accordance with Section 6.2(b) hereof.  For purposes of this
Plan, "good cause" shall be determined by the Employer in its sole and absolute
discretion.
 
     (b)  Upon the voluntary termination of employment by a Participant prior to
attaining fifty-five years of age:
 
     (1)  the amounts in each of the Participant's Deferred Benefit Accounts
shall cease to earn interest and the balance of each Deferred Benefit Account
shall be determined as of the nearest pay date following the Participant's
Employment Termination Date  determined  in accordance with Article V hereof;
and
 
     (2)  the Employer shall pay the Participant the balance of each such
Deferred Benefit Account not according to the Participant's elections as
specified in his or her Election Forms but in a lump sum, to be paid within
sixty (60) days of the Participant's voluntary termination.
 
     (c)  For purposes of this Plan, voluntary termination of employment with
the Employer by a Participant who is fifty-five years or older will in all
instances be construed to be and will be treated as an involuntary termination
by such a Participant, and the Employer will pay out to such a Participant all
amounts in his or her Deferred Benefit Account in accordance with the applicable
Election Form.

                                       8
<PAGE>
 
     (d)  Other provisions of this Plan to the contrary notwithstanding, in the
event that a Participant's employment with the Employer is terminated for any
reason within two (2) years after a "Change in Control" of Scientific-Atlanta,
Inc., the Employer shall pay the Participant the amounts in the Participant's
Deferred Benefit Accounts according to the terms of Section 6.2(a) hereof as if
the Participant had been terminated involuntarily.  For purposes of this Section
6.2(e), a "Change in Control" shall mean any of the following events:
 
     (1)  The acquisition in one or more transactions by any "Person" (as the
term person is used for purposes of Section 13(d) or 14(d) of the Securities
Exchange Act of 1934, as amended (the "1934 Act") of "Beneficial Ownership"
(within the meaning of Rule 13d-3 promulgated under the 1934 Act) of twenty
percent (20%) or more of the combined voting power of the Company's then
outstanding voting securities (the "Voting Securities"), provided, however, that
for purposes of this Section 6.2(e)(1), the Voting Securities acquired directly
from the Company by any Person shall be excluded from the determination of such
Person's Beneficial Ownership of  Voting Securities (but such Voting Securities
shall be included in the calculation of the total number of Voting Securities
then outstanding); or

     (2)  The individuals who are members of the Incumbent Board (as defined
below), cease for any reason to constitute at least two-thirds of the Board.
The "Incumbent Board" shall include the individuals who as of August 20, 1990
are members of the Board and any individual becoming a director subsequent to
August 20, 1990 whose election, or nomination for election by the Company's
stockholders, was approved by a vote of at least two-thirds of the directors
then comprising the Incumbent Board;  provided, however, that any individual who
is not a member of the Incumbent Board at the time he or she becomes a member of
the Board shall become a member of the Incumbent Board upon the completion of
two full years as a member of the Board;  provided, further, however, that
notwithstanding the foregoing, no individual shall be considered a member of the
Incumbent Board if such individual initially assumed office (i) as a result of
either an actual or threatened "election contest" (within the meaning of Rule
14a-11 promulgated under the 1934 Act) or other actual or threatened
solicitation of proxies or consents by or on behalf of a Person other than the
Board (a "Proxy Contest") or (ii) with the approval of the other Board members,
but by reason of any agreement intended to avoid or settle a Proxy Contest; or

     (3)  Approval by stockholders of the Company of (i) a merger or
consolidation involving the Company if the stockholders of the Company,
immediately before such merger or consolidation, do not own, directly or
indirectly, immediately following such merger or consolidation, more than eighty
percent (80%) of the combined voting power of the outstanding voting securities
of the corporation resulting from such merger or consolidation in substantially
the same proportion as their ownership of the Voting Securities immediately
before such merger or consolidation or (ii) a complete liquidation or
dissolution of the Company or an agreement for the sale or other disposition of
all or substantially all of the assets of the Company.

                                       9
<PAGE>
 
     Notwithstanding the foregoing, a Change in Control shall not be deemed to
occur solely because twenty percent (20%) or more of the then outstanding Voting
Securities is acquired by (i) a trustee or other fiduciary holding securities
under one or more employee benefit plans maintained by the Company or any of its
subsidiaries or (ii) any corporation which, immediately prior to such
acquisition, is owned directly or indirectly by the stockholders of the Company
in the same proportion as their ownership of stock in the Company immediately
prior to such acquisition.

     Moreover, notwithstanding the foregoing, a Change in Control shall not be
deemed to occur solely because any Person (the "Subject Person") acquired
Beneficial Ownership of more than the permitted amount of the outstanding Voting
Securities as a result of the acquisition of Voting Securities by the Company
which, by reducing the number of Voting Securities outstanding, increases the
proportional number of shares Beneficially Owned by the Subject Person,
provided, that if a Change in Control would occur (but for the operation of this
sentence) as a result of the acquisition of Voting Securities by the Company,
and after such share acquisition by the Company, the Subject Person becomes the
Beneficial Owner of any additional Voting Securities which increases the
percentage of the then outstanding Voting Securities Beneficially Owned by the
Subject Person, then a Change in Control shall be deemed to have occurred.

     6.3  Total Disability
          ----------------

     Deferred Benefits shall be paid to a Participant upon his or her becoming
Totally Disabled, as follows:

     (a)  Upon the determination that a Participant is Totally Disabled.

     (1)  No further deferrals will be made from his or her Compensation: and

     (2)  the Employer shall pay the Participant the balance in each of the
Participant's Deferred Benefit Accounts as if the Participant had been
terminated involuntarily, as set forth in Section 6.2(a).

     (b)  For purposes of this Plan, once a Participant is determined to be
Totally Disabled, he or she will continue to be deemed Totally Disabled
irrespective of the Participant's ceasing to be considered Totally Disabled for
purposes of any other plan maintained by the Employer.

     (c)  In the event that a Totally Disabled Participant recovers and resumes
active employment with the Employer such Totally Disabled Participant may resume
participation in this Plan at the discretion of the Plan Committee; provided,
however, that in any event the Totally Disabled Participant shall continue to
receive payments of Deferred Benefits that are then being paid pursuant to the
terms of this Plan.

     6.4  Death
          -----

     Deferred Benefits shall be paid upon the death of a Participant, as
follows:

     (a)  Upon the death of a Participant, the Employer shall pay the amounts in
each of the Participant's Deferred Benefit Accounts to the Beneficiary
designated by the Participant with respect to each Compensation Deferral
Election in each of his or her respective Election Forms, or, if the Participant
fails to so designate a Beneficiary, to his or her estate.
 
     (b)  If the Participant dies prior to his or her Employment Termination
Date, the Employer shall pay to each respective Beneficiary or to the
Participant's estate, as the case may be, the amounts in each of the
Participant's respective Deferred Benefit Accounts, in the same manner as for
the Participant who has been terminated involuntarily, as set forth in Section
6.2(a).
 
     (c)  If the Participant dies following his or her Employment Termination
Date but prior to his or her receiving the full payment of all Deferred Benefits
payable to him or her, the Employer shall pay to each of the respective
Beneficiaries or to the Participant's estate, as the case may be, the same
Deferred Benefit in the same manner as it otherwise would have paid to the
Participant as if the Participant had not died, unless the Participant has
specified in his or her Election Form a different manner of payment to a
Beneficiary.

     (d)  Notwithstanding the other provisions of Section 6.4, a Beneficiary may
request a different payment schedule than what has been elected by the
Participant, if such change does not further defer the scheduled payout, by
submitting a request in writing to the Plan Committee.  The granting of any such
request shall be within the discretion of the Plan Committee.

          ---------------------                                                 
of all or a portion of his or her Deferred Benefits before the Deferred Benefit
Commencement Date, as follows:

     (a)  The request for withdrawal must be to meet an "unforeseeable
emergency."

     (b)  For purposes of this Article VII, an unforeseeable emergency is a
severe financial hardship to the Participant resulting from a sudden and
unexpected illness or accident of the Participant or a dependent of the
Participant, loss of Participant's property due to casualty, or

<PAGE>
 
other similar extraordinary and unforeseeable circumstances arising as a result
of events beyond the control of the Participant. The circumstances that will
constitute an unforeseeable emergency will depend upon the facts of each case,
but, in any case, a hardship withdrawal may not be made to the extent that such
hardship is or may be relieved:

     (1)  Through reimbursement or compensation by insurance or otherwise,

     (2)  By liquidation of the participant's assets, to the extent the
liquidation of such assets would not itself cause severe financial hardship, or

     (3)  By cessation of deferrals under the Plan.

     (c)  The request for a Hardship Withdrawal must be made in writing to the
Plan Committee and shall state the amount requested, the unforeseeable emergency
to which the amount will be applied and shall also affirm that no other assets
are reasonably available to meet the emergency.

     (d)  The Plan Committee shall consider applicable regulatory standards in
assessing whether to grant a request for a Hardship Withdrawal.

     9.1  Ineligibility to Participate in Plan
          ------------------------------------

     In the event that the Plan Committee determines that a Participant has
become ineligible to continue to participate in this Plan, the Plan Committee
may terminate Participant's

<PAGE>
 
participation in this Plan upon ten (1) days' prior written notice to the
Participant. In such event, the Participant will not be entitled to make further

shall continue in effect. All Deferred Benefit Accounts shall be payable as
otherwise provided in Article VI hereof.

     9.2  Termination of Plan
          -------------------

     The Board of Directors of Scientific-Atlanta, Inc. may terminate this Plan
at any time, and termination of this Plan shall be effective upon ten (10) days'
written notice to all Participants in the Plan.  Upon such termination of this
Plan, the Employer shall pay all active Participants their Deferred Benefits as
provided in Section 6.1 as if each such Participant had actually reached the
Deferred Benefit Commencement Date for all of his or her Deferred Benefit
Accounts.  The Plan Committee may, in its discretion, accelerate all payments
due under Plan in the event of a termination of the Plan.
 
     9.3  Participant's Rights
          --------------------

     The right of a Participant or his or her Beneficiary or estate to receive
any benefits under this Plan shall be solely that of an unsecured creditor of
the Employer.  Any asset acquired or held by the Employer or funds allocated by
the Employer in connection with the liabilities assumed by the Employer pursuant
to this Plan shall not be deemed to be held under any trust for the benefit of
any Participant or of any of Participant's Beneficiaries or to be security for
the performance of the Employer's obligations hereunder but shall be and remain
a general asset of the Employer.  Provided, however, that nothing herein shall
affect the rights of the Participant with regard to this Pan under that certain
Benefits Protection Trust, between Scientific-Atlanta, Inc. and Wachovia Bank &
Trust Co., N.A., dated February 13, 1991, as amended from time to time.

     9.4  Spendthrift Provision

     Neither a Participant nor any person claiming through a Participant shall
have the right to commute, sell, assign, transfer, pledge, mortgage or otherwise
encumber, transfer, hypothecate or convey any Deferred Benefit payable hereunder
or any part thereof in advance of it actually having been received by a
Participant or other appropriate recipient under this Plan, and the right to
receive all such Deferred Benefits is expressly declared to be non-assignable
and non-transferable.  Prior to the actual payment thereof, no part of the
Deferred Benefits payable hereunder shall be subject to seizure or sequestration
for the payment of any debts, judgments, alimony or separate maintenance owed by
a Participant or any person claiming through a Participant or be transferable by
operation of law in the event of a Participant's or any such other person's
bankruptcy or insolvency.

                                       13
<PAGE>
 
     9.5  Plan Not An Employment Agreement
          --------------------------------

     This Plan shall not be deemed to constitute an employment agreement between
the Employer and any Participant, and no provision hereof shall restrict the
right of the Employer to discharge a Participant as an employee of the Employer
or the right of a Participant to voluntarily terminate his or her employment
with the Employer.

     9.6  Cooperation
          -----------

     Each Participant will cooperate with the Employer by furnishing any and all
information reasonably requested by the Employer in order to facilitate the
payment of Deferred Benefits hereunder and by taking any such other actions as
the Employer or the Plan Committee may reasonably request.

     9.7  Offset
          ------

     If a Participant or his or her Beneficiary, as the case may be, shall be
indebted to the Employer at any time that Deferred Benefits are to be paid to a
Participant or his or her Beneficiary under this Plan, then the Employer may
reduce such Deferred Benefits by the amount of such indebtedness prior to the
payment of the Deferred Benefits.

                           Article X - Miscellaneous

any respect at any time.  In addition, the Plan Committee may authorize the
following types of amendments to the Plan without Board approval:

     (a)  amendments required by law;

     (b)  amendments that relate to the administration of the Plan and that do
not materially increase the cost of the Plan; and

     (c)  amendments that are designed to resolve possible ambiguities,
inconsistencies or omissions in the Plan and that do not materially increase the
cost of the Plan.

     All authorized amendments shall be effective upon ten (10) days' written
notice to the Participants.  If any such amendment materially  adversely affects
a Participant's Deferred Benefits, such affected Participant may, within ninety
(90) days after the effective date of such amendment, elect to terminate his or
her participation in the Plan pursuant to this Section 10.1 in which event the
date of such election shall be deemed to be such Participant's Deferred Benefit

4.   ELIGIBLE PARTICIPANTS.

     4.1   DESIGNATION AND APPROVAL. Participants will be the Chief Executive
           Officer and any other senior officers who are designated and are
           approved by the Committee to receive an incentive compensation award
           under the Plan, provided, however, that if a Change in Control (as
                           --------  -------                                 
           defined in paragraph 7) occurs prior to the time Participants are
           determined for the Plan Year in which the Change in Control occurs,
           all persons who were Participants in the prior Plan Year and who are
           active employees of the Company as of the date of the Change in
           Control shall be Participants for such Plan Year.

     4.2   REQUIREMENT OF ACTIVE EMPLOYMENT AS OF DATE WHICH COMMITTEE APPROVES
           AWARDS. Except as the Committee may otherwise determine or as
           provided in paragraph 7, in order to be eligible to earn and receive
           an incentive compensation award under the Plan, a Participant for any
           Plan Year must be an active employee of the Company on the date which
           the

                                       2
<PAGE>
 
          Committee meets and approves incentive compensation awards under this
          Plan after the end of the Plan Year. Accordingly, if a Participant
          voluntarily terminates his/her employment or if the Company
          involuntarily terminates a Participant's employment prior to the date
          upon which the Committee meets after the end of the Plan Year to
          approve incentive compensation awards for that Plan Year, the
          Participant does not earn and is not eligible to receive an incentive
          compensation award under the Plan.

     4.3  PRORATED AWARDS.  The Committee may decide to award a prorated award
          to a Participant who is newly hired during the Plan Year.  Prorated
          awards may also be given to Participants who Retire during a Plan Year
          and to the estates of Participants who die during a Plan Year.

5.   DETERMINATION OF INCENTIVE COMPENSATION AWARDS.

     5.1  TARGETS.  Each Participant will have a Target established for him/her
          by the Company for the Plan Year.

     5.2  PERFORMANCE OBJECTIVES.  The Committee shall establish one or more
          specific Performance Objectives for a Plan Year, and such Performance
          Objectives shall be established within ninety (90) days of the
          beginning of the Plan Year. The Committee shall also establish a
          schedule or schedules setting forth the amount to be paid based on the
          extent to which the Performance Objectives are actually achieved as
          determined by the Committee. The Committee may at any time adjust the
          Performance Objectives and any schedules of payments related thereto
          or adjust the way Performance Objectives are measured, provided that
          this provision shall not apply to any payment that is intended to
          qualify as performance-based compensation under Code Section
          162(m)(4)(C), if and to the extent that it would prevent the payment
          from so qualifying. The Committee shall have the right to reduce or
          eliminate the compensation payable upon the attainment of a
          Performance Objective but shall not have the discretion to increase a
          payment upon the attainment of a Performance Objective.

6.   PAYMENT OF INCENTIVE COMPENSATION AWARDS

     6.1  TIME OF PAYMENT.  Except as provided in paragraph 7, incentive
          compensation awards under this Plan will be fully paid in cash within
          ninety (90) days after the end of the Plan Year, or deferred in whole
          or in part based on a written request for deferral submitted by the
          Participant and approved by the Company in accordance with procedures
          established by the Company.

     6.2  TREATMENT OF AWARD AS COMPENSATION.  Any amounts paid as incentive
          compensation under this Plan shall be considered as compensation to
          the Participant for purposes of the Retirement Plan and disability and
          life insurance programs, unless and to the extent that such
          compensation is expressly excluded by the provisions of the Retirement
          Plan or the instruments establishing such programs, but such amounts
          shall not be considered as compensation for purposes of any other
          incentive plan or other benefits unless 

                                       3
<PAGE>
 
          the written instrument establishing such other plan or benefits
          expressly includes compensation paid under this Plan.

     6.3  MAXIMUM AWARD.  The maximum dollar value with respect to payments
          under this Plan to any Participant in any single Plan Year shall be
          $600,000.

7.   CHANGE IN CONTROL OF THE COMPANY

     7.1  CONTRARY PROVISIONS.  Notwithstanding anything contained in the Plan
          to the contrary, the provisions of this paragraph 7 shall govern and
          supersede any inconsistent terms or provisions of the Plan.

     7.2  CHANGE IN CONTROL.  For purposes of the Plan, Change in Control shall
          mean any of the following events:

          7.2.1  The acquisition in one or more transactions by any "Person" (as
                 the term person is used for purposes of Section 13(d) or 14(d)
                 of the Securities Exchange Act of 1934, as amended (the "1934
                 Act")) of "Beneficial Ownership" (within the meaning of Rule
                 13d-3 promulgated under the 1934 Act) of twenty percent (20%)
                 or more of the combined voting power of the Company's then
                 outstanding voting securities (the "Voting Securities");
                 provided, however, that for purposes of this paragraph 8(b)(1),
                 --------  ------- 
                 the Voting Securities acquired directly from the Company by any
                 Person shall be excluded from the determination of such
                 Person's beneficial Ownership of Voting Securities (but such
                 Voting Securities shall be included in the calculation of the
                 total number of Voting Securities then outstanding); or

          7.2.2  The individuals who are members of the Incumbent Board (as
                 defined below) cease for any reason to constitute at least two-
                 thirds (2/3) of the Board. The "Incumbent Board" shall include
                 the individuals who as of August 20, 1990 are members of the
                 Board and any individual becoming a director subsequent to
                 August 20, 1990 whose election, or nomination for election by
                 the Company's stockholders was approved by a vote of at least
                 two-thirds (2/3) of the directors then comprising the Incumbent
                 Board; provided, however, that any individual who is not a
                        --------  -------
                 member of the Incumbent Board at the time he or she becomes a
                 member of the Board shall become a member of the Incumbent
                 Board upon the completion of two (2) full years as a member of
                 the Board; provided, further, however, that notwithstanding the
                            --------  -------  -------
                 foregoing, no individual shall be considered a member of the
                 Incumbent Board if such individual initially assumed office (i)
                 as a result of either an actual or threatened "election
                 contest" (within the meaning of Rule 14a-11 promulgated under
                 the 1934 Act) or other actual or threatened solicitation of
                 proxies or consents by or on behalf of a Person other than the
                 Board (a "Proxy Contest") or (ii) with the approval of the
                 other Board members, but by reason of any agreement intended to
                 avoid or settle a Proxy Contest; or

          7.2.3  Approval by stockholders of the Company of (i) a merger or
                 consolidation involving the Company if the stockholders of the
                 Company, immediately before such merger or consolidation, do
                 not own, directly or indirectly immediately following such
                 merger or consolidation, more than eighty percent (80%) of the
                 combined voting power of the outstanding voting securities of
                 the Company resulting from such merger or consolidation in
                 substantially the same proportion as their ownership of the
                 Voting Securities immediately before such merger or
                 consolidation or (ii) a complete liquidation or dissolution of
                 the Company or an agreement for the sale or other disposition
                 of all or substantially all of the assets of the Company.

          7.2.4  Notwithstanding the foregoing, a Change in Control shall not be
                 deemed to occur solely because twenty percent (20%) or more of
                 the then outstanding Voting Securities is acquired by (i) a
                 trustee or other fiduciary holding securities under one or more
                 employee benefit plans maintained by the Company or (ii) any
                 corporation which, immediately prior to such acquisition, is
                 owned directly or indirectly by the stockholders of the Company
                 in the same proportion as their ownership of stock in the
                 Company immediately prior to such acquisition.

          7.2.5  Moreover, notwithstanding the foregoing, a Change in Control
                 shall not be deemed to occur solely because any Person (the
                 "Subject Person") acquired Beneficial Ownership of more than
                 the permitted amount of the outstanding Voting Securities as a
                 result of the acquisition of Voting Securities by the Company
                 which, by reducing the number of Voting Securities outstanding,
                 increases the proportional number of shares Beneficially Owned
                 by the Subject Person, provided, that if a Change in Control
                                        -------- 
                 would occur (but for the operation of this sentence) as a
                 result of the acquisition of Voting Securities by the Company,
                 and after such share acquisition by the Company the Subject
                 Person becomes the Beneficial Owner of any additional Voting
                 Securities which increases the Percentage of the then
                 outstanding Voting Securities Beneficially Owned by the Subject
                 Person, the a Change in Control shall occur.

          7.2.6  Notwithstanding anything contained in this Plan to the
                 contrary, if a Participant's employment is terminated prior to
                 a Change in Control and the Participant reasonably demonstrates
                 that such termination (i) was at the request of a third party
                 who has indicated an intention or taken steps reasonably
                 calculated to effect a Change in Control who effectuates a
                 Change in Control or (ii) otherwise occurred in connection with
                 or in anticipation of a Change in Control which actually
                 occurs, then for all purposes of this Plan, the date of a
                 Change in Control in respect of such Participant shall mean the
                 date immediately prior to the date of termination of such
                 Participant's employment.

     7.3  PAYMENT UPON A CHANGE IN CONTROL.  Upon a Change in Control, the
          incentive compensation award for a Plan Year ending prior to the date
          of the 

                                       5
<PAGE>
 
          Change in Control for which payment has not previously been made shall
          be unconditionally payable in cash to each Participant.

          7.3.1  If a Change in Control occurs with approval of the Board
                 granted prior to any such Change in Control, incentive
                 compensation awards for the Plan Year during which the Change
                 in Control occurs shall be unconditionally payable to each
                 Participant, such awards to be the Target percentage of each
                 Participant's base salary or such higher percentage a may be
                 approved by the Committee.

          7.3.2  If a Change in Control occurs without approval of the Board
                 granted prior to any such Change in Control, incentive
                 compensation awards for the Plan Year during which the Change
                 in Control occurs shall be unconditionally payable to each
                 Participant, such awards to be two (2) times the Target
                 percentage of each Participant's base salary; provided,
                                                               --------
                 however, that in any case, if a Change in Control occurs before
                 ------- 
                 Target percentages shall have been established for a Plan Year,
                 the Target percentages for such Plan Year shall be no less
                 favorable to the Participants than the Target percentages for
                 the prior Plan Year. Unless the Committee directs an earlier
                 payment, incentive compensation awards payable in accordance
                 with this paragraph 7.3.2 shall be paid in cash on or before
                 the earlier of the date which is five (5) days following the
                 date of the Change of Control or the date determined in
                 accordance with paragraph 6 above.

     7.4  CONTINUATION OF THE PLAN. For a period of two (2) Plan Years following
          the Plan Year in which a Change of Control occurs, the Plan shall not
          be terminated or amended in any way (including, but not limited to,
          restricting or limiting the right to participate in the Plan of any
          person who is a Participant on the day prior to the date of the Change
          in Control), nor shall the manner in which the Plan is administered be
          changed in a way that adversely affects the level of participation or
          reward opportunities of any Participant; provided, however, that the
                                                   --------  -------
          Plan shall be amended as necessary to make appropriate adjustments for
          (i) any negative effect that the costs of expenses incurred by the
          Company in connection with the Change in Control may have on the
          benefits payable under the Plan and (ii) any changes to the Company
          (including, but not limited to, changes in corporate structure or
          capitalization, acquisitions or dispositions and increased interest
          expense as a result of the incurrence or assumption by the Company of
          acquisition indebtedness) following the Change in Control so as to
          preserve the reward opportunities and performance targets for
          comparable performance under the Plan as in effect on the date
          immediately prior to the Change in Control.

     7.5  NO AMENDMENT OR TERMINATION OF CHANGE IN CONTROL PROVISION.  This
          paragraph 7 shall not be amended or terminated at any time.  Any
          amendment or termination of the Plan prior to a Change in Control
          which (i) was at the request of a third party who has indicated an
          intention or taken steps reasonably calculated to effect a Change in
          Control or (ii) otherwise arose in 

                                       6
<PAGE>
 
          connection with or in anticipation of a Change in Control shall be
          null and void and shall have no effect whatsoever.

     7.6  TRUST ARRANGEMENT.  All benefits under the Plan shall be paid by the
          Company.  The Plan shall be unfunded, and the benefits hereunder shall
          be paid only from the general asset of the Company; provided, however,
                                                              --------  ------- 
          nothing herein shall prevent or prohibit the Company from establishing
          a trust or other arrangement for the purpose of providing for the
          payment of the benefits payable under the Plan.

8.   NON-ASSIGNABILITY.  No payment awarded under this Plan nor any right or
     benefit under this Plan shall be subject to anticipation, alienation, sale,
     assignment, pledge, encumbrance or charge, and any attempt to anticipate,
     alienate, sell, assign, pledge, encumber or charge the same shall be void
     and shall not be recognized or given effect by the Company.

9.   AMENDMENT OF THE PLAN.  This Plan may be amended at any time and from time
     to time by the Board, provided that no amendment to the Plan which would
     change the material terms of performance goals that were previously
     approved by the Company's stockholders within the meaning of Proposed
     Treasury Regulation Section 1.162.27(e)(4)(vi) or a successor provision
     shall be made without the approval of the stockholders of the Company,
     unless the Board determines that such approval:  (i) is not necessary to
     avoid loss of a deduction under Section 162(m) of the Code, (ii) will not
     avoid such a loss of deduction or (iii) is not advisable.

10.  NO RIGHT TO EMPLOYMENT.  Nothing in this Plan or in any notice of award
     pursuant to this Plan shall confer upon any person the right to continue in
     the employment of the Company or affect the Company's right to terminate
     the employment of any person.

11.  PERFORMANCE-BASED COMPENSATION.  This Plan is intended to give the
     Committee the authority, in its discretion, to make payments that qualify
     as performance-based compensation under Code Section 162(m)(4)(C).

12.  GOVERNING LAW.  This Plan and the rights of all persons claiming rights
     under the Plan shall be governed by and interpreted in accordance with the
     laws of the State of Georgia, excluding its provisions regarding conflicts

<PAGE>
 
3.   ADMINISTRATION AND INTERPRETATION OF THE PLAN.  The Committee shall have
     the sole and exclusive discretionary power to (i) approve eligible
     Participants, (ii) approve awards and payments under the Plan, (iii)
     interpret and construe the Plan, (iv) adopt, amend and rescind rules and

     Chief Executive Officer of the Company or to other officers of the Company
     in the Committee's discretion.

     The decision of the Committee on any question concerning the interpretation
     and administration of the Plan shall be final and conclusive.  The
     Committee's determinations may differ in the Committee's sole discretion
     between different Participants, irrespective of whether they are similarly

     employee, his/her legal representative or assigns, any right to a payment
     or otherwise to participate in the Plan, except as the Committee may
     determine after the conclusion of a Plan Year.

4.   ELIGIBLE PARTICIPANTS.

     4.1  DESIGNATION AND APPROVAL.  Participants will be designated from the
          Key Employees by the Chief Executive Officer of the Company and
          approved by the Committee in order to be eligible to receive an
          incentive compensation award under the Plan; provided, however, that
                                                       --------  -------      
          if a Change in Control (as defined in paragraph 7) occurs prior to the
          time Participants are determined for the Plan Year in which the Change
          in Control occurs, all persons who were Participants in the prior Plan
          Year and who are active employees of the Company as of the date of the
          Change in Control shall be Participants for such Plan Year.

     4.2  REQUIREMENT OF ACTIVE EMPLOYMENT AS OF DATE WHICH COMMITTEE APPROVES
          AWARDS.  Except as the Committee may otherwise determine or as
          provided in paragraph 7, in order to be eligible to earn and receive
          an incentive compensation award under the Plan, a Participant for any
          Plan Year must be an active employee of the Company on the date which
          the Committee meets and approves incentive compensation awards under
          this Plan after the end of the Plan Year.  Accordingly, if a
          Participant voluntarily terminates his/her employment or if the
          Company involuntarily terminates a Participant's employment prior to
          the date upon which the Committee meets after the end of the Plan Year
          to approve incentive compensation awards for that Plan Year, the
          Participant does not earn and is not eligible to receive an incentive
          compensation award under the Plan.

     4.3  PRORATED AWARDS.  The Committee may decide to award a prorated award
          to a Participant who is newly hired during the Plan Year or who is
          transferred from one Business Unit within the Company to another
          during a Plan Year, based on each Business Unit's results.  Prorated
          awards may also be given to Participants who Retire during a Plan Year
          and to the estates of Participants who die during a Plan Year.

                                       3

5.  DETERMINATION OF INCENTIVE COMPENSATION AWARDS

     5.1  TARGETS.  Each Participant will have a Target established for him/her
          by the Company for the Plan Year.

     5.2  FACTORS TO BE USED IN DETERMINATION OF AWARDS.  Incentive Compensation
          awards under the Plan shall be calculated using a quantitative factor
          and a qualitative factor.  These factors will be established as early
          in the Plan Year as practicable.

          5.2.1  The quantitative factor shall be determined using Company,
                 Business Unit or Function results, as appropriate.

          5.2.2  The qualitative factor shall be determined by assessing the
                 Participant's individual accomplishment of qualitative
                 objectives established for the Participant for the Plan Year.
                 The following procedure will be used in making appraisals of
                 individual performance:

                 (a)  At the beginning of the Plan Year, each person eligible to
                      be a Participant and his superior will mutually establish
                      individual performance objectives. These objectives should
                      be specific and committed to writing. Copies of agreed-to
                      objectives for all Participants should be forwarded to the
                      respective Human Resources Director or the Senior Vice
                      President of Human Resources.

                 (b)  If during the year objectives are modified, deleted or
                      added, an amended list of objectives should be prepared,
                      agreed and forwarded to the office of the respective Human
                      Resources Director or the Senior Vice President of Human
                      Resources.

                 (c)  At the end of the Plan Year, eligible Participants and
                      their superiors will be asked to assess the degree to
                      which the stated performance objectives were achieved.
                      These assessments will be combined with the quantitative
                      performance results and translated into incentive
                      compensation awards to be recommended by the Chief
                      Executive Officer of the Company and approved by the
                      Committee. The Committee reserves the authority to
                      exercise its judgment and approve justifiable exceptions
                      to award levels determined solely by strict application of
                      weightings and calculations under Plan provisions.

     5.3  WEIGHTING OF FACTORS.  The weighting of the quantitative and
          qualitative objectives for any fiscal year in which the Plan is in
          effect will be determined by the Company in its discretion.

                                       4

6.   PAYMENT OF INCENTIVE COMPENSATION AWARDS.  Except as provided in paragraph
     7, incentive compensation awards under this Plan will be fully paid in cash
     within ninety (90) days after the end of the Plan Year, or deferred in
     whole or in part based on a written request for deferral submitted by the
     Participant and approved by the Company in accordance with procedures
     established by the Company.

7.  CHANGE IN CONTROL OF THE COMPANY

     7.1  CONTRARY PROVISIONS.  Notwithstanding anything contained in the Plan
          to the contrary, the provisions of this paragraph 7 shall govern and

                 13d-3 promulgated under the 1934 Act) of twenty percent (20%)
                 or more of the combined voting power of the Company's then
                 outstanding voting securities (the "Voting Securities");
                 provided, however, that for purposes of this paragraph 8(b)(1),
                 --------  ------- 
                 the Voting Securities acquired directly from the Company by any
                 Person shall be excluded from the determination of such
                 Person's beneficial Ownership of Voting Securities (but such
                 Voting Securities shall be included in the calculation of the
                 total number of Voting Securities then outstanding); or

          7.2.2  The individuals who are members of the Incumbent Board (as
                 defined below) cease for any reason to constitute at least two-
                 thirds (2/3) of the Board. The "Incumbent Board" shall include
                 the individuals who as of August 23, 1993 are members of the
                 Board and any individual becoming a director subsequent to
                 August 23, 1993 whose election, or nomination for election by
                 the Company's stockholders was approved by a vote of at least
                 two-thirds (2/3) of the directors then comprising the Incumbent
                 Board; provided, however, that any individual who is not a
                        --------  -------     
                 member of the Incumbent Board at the time he or she becomes a
                 member of the Board shall become a member of the Incumbent
                 Board upon the completion of two (2) full years as a member of
                 the Board; provided, further, however, that notwithstanding the
                            --------  -------  -------   
                 foregoing, no individual shall be considered a member of the
                 Incumbent Board if such individual initially assumed office (i)
                 as a result of either an actual or threatened "election
                 contest" (within the meaning of Rule 14a-11 promulgated under
                 the 1934 Act) or other actual or threatened solicitation of
                 proxies or consents by or on behalf of a Person other than the
                 Board (a "Proxy Contest") or (ii) with the approval of the
                 other Board members, but by reason of any agreement intended to
                 avoid or settle a Proxy Contest; or

          7.2.3  Approval by stockholders of the Company of (i) a merger or
                 consolidation involving the Company if the stockholders of the
                 Company, immediately before such merger or consolidation, do
                 not own, directly or indirectly immediately following such
                 merger or consolidation, more than eighty percent (80%) of the
                 combined voting power of the outstanding voting securities of
                 the Company resulting from such merger or consolidation in
                 substantially the same proportion as their ownership of the
                 Voting Securities immediately before such merger or
                 consolidation or (ii) a complete liquidation or dissolution of
                 the Company or an agreement for the sale or other disposition
                 of all or substantially all of the assets of the Company.

          7.2.4  Notwithstanding the foregoing, a Change in Control shall not be
                 deemed to occur solely because twenty percent (20%) or more of
                 the then outstanding Voting Securities is acquired by (i) a
                 trustee or other fiduciary holding securities under one or more
                 employee benefit plans maintained by the Company or (ii) any
                 corporation which, immediately prior to such acquisition, is
                 owned directly or indirectly by the stockholders of the Company
                 in the same proportion as their ownership of stock in the
                 Company immediately prior to such acquisition.

          7.2.5  Moreover, notwithstanding the foregoing, a Change in Control
                 shall not be deemed to occur solely because any Person (the
                 "Subject Person") acquired Beneficial Ownership of more than
                 the permitted amount of the outstanding Voting Securities as a
                 result of the acquisition of Voting Securities by the Company
                 which, by reducing the number of Voting Securities outstanding,
                 increases the proportional number of shares Beneficially Owned
                 by the Subject Person, provided, that if a Change in Control
                                        --------    
                 would occur (but for the operation of this sentence) as a
                 result of the acquisition of Voting Securities by the Company,
                 and after such share acquisition by the Company the Subject
                 Person becomes the Beneficial Owner of any additional Voting
                 Securities which increases the Percentage of the then
                 outstanding Voting Securities Beneficially Owned by the Subject
                 Person, then a Change in Control shall occur.

          7.2.6  Notwithstanding anything contained in this Plan to the
                 contrary, if a Participant's employment is terminated prior to
                 a Change in Control and the Participant reasonably demonstrates
                 that such termination (i) was at the request of a third party
                 who has indicated an intention or taken steps reasonably
                 calculated to effect a Change in Control and who effectuates a
                 Change in Control or (ii) otherwise occurred in connection with
                 or in anticipation of a Change in Control which actually
                 occurs, then for all purposes of this Plan, the date of a
                 Change in Control in respect of such Participant shall mean the
                 date immediately prior to the date of termination of such
                 Participant's employment.

     7.3  PAYMENT UPON A CHANGE IN CONTROL.  Upon a Change in Control, the
          incentive compensation award for a Plan Year ending prior to the date
          of the 

                                       6
<PAGE>
 
          Change in Control for which payment has not previously been made shall
          be unconditionally payable in cash to each Participant.

          7.3.1  If a Change in Control occurs with approval of the Board
                 granted prior to any such Change in Control, incentive
                 compensation awards for the Plan Year during which the Change
                 in Control occurs shall be unconditionally payable to each
                 Participant, such awards to be the Target percentage of each
                 Participant's base salary or such higher percentage as may be
                 approved by the Committee.

          7.3.2  If a Change in Control occurs without approval of the Board
                 granted prior to any such Change in Control, incentive
                 compensation awards for the Plan Year during which the Change
                 in Control occurs shall be unconditionally payable to each
                 Participant, such awards to be two (2) times the Target
                 percentage of each Participant's base salary; provided,
                                                               --------
                 however, that in any case, if a Change in Control occurs before
                 ------- 
                 Target percentages shall have been established for a Plan Year,
                 the Target percentages for such Plan Year shall be no less
                 favorable to the Participants than the Target percentages for
                 the prior Plan Year. Unless the Committee directs an earlier
                 payment, incentive compensation awards payable in accordance
                 with this paragraph 7.3.2 shall be paid in cash on or before
                 the earlier of the date which is five (5) days following the
                 date of the Change of Control or the date determined in
                 accordance with paragraph 6 above.

     7.4  CONTINUATION OF THE PLAN.  For a period of two (2) Plan Years
          following the Plan Year in which a Change of Control occurs, the Plan
          shall not be terminated or amended in any way (including, but not
          limited to, restricting or limiting the right to participate in the
          Plan of any person who is a Participant on the day prior to the date
          of the Change in Control), nor shall the manner in which the Plan is
          administered be changed in a way that adversely affects the level of
          participation or reward opportunities of any Participant; provided,
                                                                    -------- 
          however, that the Plan shall be amended as necessary to make
          -------                                                     
          appropriate adjustments for (i) any negative effect that the costs of
          expenses incurred by the Company in connection with the Change in
          Control may have on the benefits payable under the Plan and (ii) any
          changes to the Company (including, but not limited to, changes in
          corporate structure or capitalization, acquisitions or dispositions
          and increased interest expense as a result of the incurrence or
          assumption by the Company of acquisition indebtedness) following the
          Change in Control so as to preserve the reward opportunities and
          performance targets for comparable performance under the Plan as in
          effect on the date immediately prior to the Change in Control.

     7.5  NO AMENDMENT OR TERMINATION OF CHANGE IN CONTROL PROVISION.  This
          paragraph 7 shall not be amended or terminated at any time.  Any
          amendment or termination of the Plan prior to a Change in Control
          which (i) was at the request of a third party who has indicated an
          intention or taken steps reasonably calculated to effect a Change in
          Control or (ii) otherwise arose in 

                                       7
<PAGE>
 
          connection with or in anticipation of a Change in Control shall be
          null and void and shall have no effect whatsoever.

     7.6  TRUST ARRANGEMENT.  All benefits under the Plan shall be paid by the
          Company.  The Plan shall be unfunded, and the benefits hereunder shall
          be paid only from the general asset of the Company; provided, however,
                                                              --------  ------- 
          nothing herein shall prevent or prohibit the Company from establishing
          a trust or other arrangement for the purpose of providing for the
          payment of the benefits payable under the Plan.

8.   NON-ASSIGNABILITY.  No payment awarded under this Plan nor any right or
     benefit under this Plan shall be subject to anticipation, alienation, sale,
     assignment, pledge, encumbrance or charge, and any attempt to anticipate,
     alienate, sell, assign, pledge, encumber or charge the same shall be void
     and shall not be recognized or given effect by the Company.

9.   AMENDMENT OF PLAN.  Subject to the restrictions set forth in Section 7.5,
     the Committee has the authority to amend or modify this Plan at any time in
     its discretion.

10.  TERMINATION OF PLAN.  Subject to the restrictions set forth in Section 7.5
     and in this Section 10, the Committee also has the authority to terminate
     this Plan at any time.  At its August meeting in each Plan Year, the
     Committee may terminate the Plan for that Plan Year in its discretion.  In
     the event of termination at the August meeting, no Participant will be
     entitled to any incentive compensation award under the Plan for that Plan
     Year.  If the Committee terminates the Plan at any time other than the
     August meeting, such termination may only be prospective and Participants
     will be entitled to receive a pro-rata incentive compensation award
     calculated under the terms and conditions of the Plan for the Plan Year in
     which the termination occurs.

11.  NO RIGHT TO EMPLOYMENT.  Nothing in the Plan or in any notice of award
     pursuant to the Plan shall confer upon any person the right to continue in
     the employment of the Company nor affect the Company's right to terminate
     the employment of any person.

12.  GOVERNING LAW.  This Plan and the rights of all persons claiming rights
     under the Plan shall be governed by and interpreted in accordance with the
     laws of the State of Georgia, excluding its provisions regarding conflicts
     of laws.

          ------------

          provided by the Committee, but in no event may the Committee delay the
          commencement of benefits beyond the Participant's Normal Retirement
          Date.

          If the Committee elects to delay the commencement of a Participant's
          retirement benefits under this subsection, the amount payable as of
          the delayed commencement date shall be adjusted in accordance with the
          Retirement Plan to reflect this delay.

     (b)  Employment Beyond Age Sixty-Five (65).  Notwithstanding any other
          -------------------------------------                            
          provision in this Plan to the contrary, in the case of a Participant
          who remains an Employee after his Normal Retirement Date, the
          Committee may direct, in its sole and absolute discretion, that the
          Participant's retirement benefit shall commence as of any date on or
          after his or her Normal Retirement Date and prior to his or her
          Severance from Service Date.  Any such Participant shall receive a
          retirement benefit calculated pursuant to section 4.1 as of the
          commencement date selected by the Committee.  The retirement benefit
          payable to the Participant upon his or her subsequent Severance from
          Service Date shall be equal to the greater of:

          (1)  the retirement benefit determined under section 4.1 as of the
               first day of the month following his or her Severance from
               Service Date, reduced by following the provisions of Code section

          (2)  the retirement benefit determined under section 4.1 as of his or
               her Normal Retirement Date, increased by applying interest at an
               annual rate of five percent (5%) (allocated quarterly) from his
               or her Normal Retirement Date until the benefit commencement date
               selected by the Committee.

     (a)  Unmarried Participant.  The form of payment for a Participant who is

          life annuity.  In the case of a benefit calculated as a lump sum

               Participant's surviving spouse for life equal to fifty percent
               (50%) of the amount payable during the Participant's lifetime.

               This joint and fifty percent (50%) surviving spouse annuity shall
               be the Actuarial Equivalent of the single life annuity described
               in subsection (a).

     (c)  Optional Payment Forms.  In lieu of the normal form of payment
          ----------------------

          sole and absolute discretion, that benefits shall be paid in one of
          the optional forms of payment available under the Retirement Plan.  In

          be the Actuarial Equivalent of the single life annuity described in

          any later month, but in no event beyond the first day of the month in
          which the Participant would have attained age sixty-five (65).  If the
          Committee elects to delay the commencement of a Pre-retirement death
          benefit pursuant to this subsection, the amount payable as of the
          delayed commencement date shall be adjusted in accordance with the

          employment with the Employer is terminated during the two (2) year
          period following a Change in Control for any reason other than cause,
          the Participant shall receive a lump sum payment equal to the
          Actuarial Equivalent value of the Participant's accrued benefit as of
          the date of such termination.
 
     (c)  Amendment or Termination.  For a period of two (2) Plan Years
          ------------------------                                     
          following the Plan Year in which a Change in Control occurs, the Plan
          shall not be terminated or amended in any way that would reduce or
          otherwise adversely affect the computation or amount of, or
          entitlement to, benefits hereunder (including, but not limited to,
          restricting or limiting the right to participate in the Plan of any
          person who is a Participant on the day prior to the date of the Change
          in Control).  Any amendment or termination of the Plan prior to a
          Change in Control which a Participant who is an Employee at the time
          of the amendment or termination reasonably demonstrates (1) was at the
          request of a third party who has indicated an intention or taken steps
          reasonably calculated to effect a Change in Control, or (2) otherwise
          arose in connection with or in anticipation of a Change in Control,
          and which was not consented to in writing by such Participant, shall
          be null and void and shall have no effect whatsoever.
 
     (d)  Definition of Change in Control.  For purposes of this section, a
          -------------------------------                                  
          Change in Control shall mean any of the following events:
 
          (1)  The acquisition in one or more transactions by any "Person" (as
               the term person is used for purposes of section 13(d) or 14(d) of
               the Securities Exchange Act of 1934, as amended (the "Exchange
               Act")) of "Beneficial Ownership" (within the meaning of Rule 13d-
               3 promulgated under the Exchange Act) of twenty percent (20%) or
               more of the combined voting power of the Company's then
               outstanding voting securities (the "Voting Securities"),
               provided, however, that for purposes of this section, any Voting
               Securities acquired directly from the Company by any Person shall
               be excluded from the determination of such Person's Beneficial

                                       8
<PAGE>
 
               Ownership of Voting Securities (but such Voting Securities shall
               be included in the calculation of the total number of Voting
               Securities then outstanding);
 
          (2)  The individuals who are members of the Incumbent Board (as
               defined below) cease for any reason to constitute at least two-
               thirds of the Board.  The "Incumbent Board" shall include the
               individuals who as of August 20, 1990 were members of the Board
               and any individual becoming a director subsequent to August 20,
               1990 whose election, or nomination for election by the Company's
               stockholders, was approved by a vote of at least two-thirds (2/3)
               of the directors then comprising the Incumbent Board, provided,
               however, that any individual who is not a member of the Incumbent
               Board at the time he or she becomes a member of the Board shall
               become a member of the Incumbent Board upon the completion of two
               full years as a member of the Board, provided further, however,
               that notwithstanding the foregoing, no individual shall be
               considered a member of the Incumbent Board if such individual
               initially assumed office (A) as a result of either an actual or
               threatened "election contest" (within the meaning of Rule 14a-11
               promulgated under the Exchange Act) or other actual or threatened
               solicitation of proxies or consents by or on behalf of a Person
               other than the Board (a "Proxy Contest"), or (B) with the
               approval of the other Board members, but by reason of any
               agreement intended to avoid or settle a Proxy Contest;
 
          (3)  Approval by stockholders of the Company of (A) a merger or
               consolidation involving the Company if the stockholders of the
               Company, immediately before such merger or consolidation, do not
               own, directly or indirectly immediately following such merger or
               consolidation, more than eighty percent (80%) of the combined
               voting power of the outstanding voting securities of the
               corporation resulting from such merger or consolidation in
               substantially the same proportion as their ownership of the
               Voting Securities immediately before such merger or
               consolidation, or (B) a complete liquidation or dissolution of
               the Company or an agreement for the sale or other disposition of
               all or substantially all of the assets of the Company.
 
          Notwithstanding the foregoing, a Change in Control shall not be deemed
to occur solely because twenty percent (20%) or more of the then outstanding
Voting Securities is acquired by (i) a trustee or other fiduciary holding
securities under one or more employee benefit plans maintained by the Company or
any of its Affiliates, or (ii) any corporation that, immediately prior to such
acquisition, is owned directly or indirectly by the stockholders of the Company
in the same proportion as their ownership of stock in the Company immediately
prior to such acquisition.

                                       9
<PAGE>
 
          Moreover, notwithstanding the foregoing, a Change in Control shall not
be deemed to occur solely because any Person (the "Subject Person") acquired
Beneficial Ownership of more than the permitted amount of the outstanding Voting
Securities as a result of the acquisition of Voting Securities by the Company
that, by reducing the number of Voting Securities outstanding, increases the
proportional number of shares Beneficially Owned by the Subject Person,
provided, that if a Change in Control would occur (but for the operation of this
sentence) as a result of the acquisition of Voting Securities by the Company,
and after such share acquisition by the Company the Subject Person becomes the
Beneficial Owner of any additional Voting Securities that increase the
percentage of the then outstanding Voting Securities Beneficially Owned by the
Subject Person, then a Change in Control shall occur.

          Notwithstanding anything contained in this Plan to the contrary, if a
Participant's employment is terminated prior to a Change in Control and the
Participant reasonably demonstrates that such termination (1) was at the request
of a third party who has indicated an intention or taken steps reasonably
calculated to effect a Change in Control and who effectuates a Change in
Control, or (2) otherwise occurred in connection with or in anticipation of a
Change in Control that actually occurs, then for all purposes of this Plan, the
date of a Change in Control in respect of such Participant shall mean the date
immediately prior to the date of termination of such Participant's employment.

                             Article V.  Financing
                             ---------------------

     5.1  Financing.  The benefits under this Plan shall be paid out of the
          ---------                                                         
general assets of the Employers, except to the extent they are paid from the
assets of a grantor trust established by an Employer to pay these benefits.

     5.2  Unsecured Interest.  No Participant shall have any interest
          ------------------                                           
whatsoever in any specific asset of the Company or an Affiliate.  To the extent
that any person acquires a right to receive payments under this Plan, such right
shall be no greater than the right of any unsecured general creditor of an
Employer.

                          Article VI.  Administration
                          ---------------------------

     6.1  Administration.  The Plan shall be administered by the Committee.
          --------------                                                    

          The Committee shall have all powers necessary or appropriate to carry
out the provisions of the Plan.  It may, from time to time, establish rules for
the administration of the Plan and the transaction of the Plan's business.  In
its sole discretion, the Committee may delegate any or all of its
responsibilities relative to administration of the Plan to such officers of the
Company as it designates.

          The Committee shall have the exclusive right to make any finding of
fact necessary or appropriate for any purpose under the Plan including, but not
limited to, the determination of eligibility for and amount of any benefit.

                                       10
<PAGE>
 
          The Committee shall have the exclusive right to interpret the terms
and provisions of the Plan and to determine any and all questions arising under
the Plan or in connection with its administration, including, without
limitation, the right to remedy or resolve possible ambiguities,
inconsistencies, or omissions by general rule or particular decision, all in its
sole and absolute discretion.

          To the extent permitted by law, all findings of fact, determinations,
interpretations, and decisions of the Committee shall be conclusive and binding
upon all persons having or claiming to have any interest or right under the
Plan.

     6.2  Appeals from Denial of Claims.  If any claim for benefits under the
          -----------------------------                                        
Plan is wholly or partially denied, the claimant shall be given notice of the
denial.  This notice shall be in writing, within a reasonable period of time
after receipt of the claim by the Committee.  This period shall not exceed
ninety (90) days after receipt of the claim, except that if special
circumstances require an extension of time, written notice of the extension
shall be furnished to the claimant, and an additional ninety (90) days will be
considered reasonable.

          This notice shall be written in a manner calculated to be understood
by the claimant and shall set forth the following information:

     (a)  the specific reasons for the denial;

     (b)  specific reference to the Plan provisions on which the denial is
          based;

     (c)  a description of any additional material or information necessary for
          the claimant to perfect the claim and an explanation of why this
          material or information is necessary;

     (d)  an explanation that a full and fair review by the Committee of the
          decision denying the claim may be requested by the claimant or an
          authorized representative by filing with the Committee, within sixty
          (60) days after the notice has been received, a written request for
          the review; and
 
     (e)  if this request is so filed, an explanation that the claimant or an
          authorized representative may review pertinent documents and submit
          issues and comments in writing within the same sixty (60) day period
          specified in subsection (d).

          The decision of the Committee upon review shall be made promptly, and
not later than sixty (60) days after the Committee's receipt of the request for
review, unless special circumstances require an extension of time for
processing.  In this case the claimant shall be so notified, and a decision
shall be rendered as soon as possible, but not later than one hundred twenty
(120) days after receipt of the request for review.  If the claim is denied,
wholly or in part, the claimant shall be given a copy of the decision promptly.
The decision shall be in writing, shall include specific reasons for the denial,
shall include specific references to the pertinent Plan 

                                       11
<PAGE>
 
provisions on which the denial is based, and shall be written in a manner
calculated to be understood by the claimant.

     6.3  Tax Withholding.  The Employer may withhold from any payment under
          ---------------                                                     
this Plan any federal, state, or local taxes required by law to be withheld with
respect to the payment and any sum the Employer may reasonably estimate as
necessary to cover any taxes for which the Employer may be liable and that may
be assessed with regard to the payment.

     6.4  Expenses.  All expenses incurred in the administration of the Plan
          --------                                                            
shall be paid by the Employers.

                Article VII.  Adoption of the Plan by Affiliate;
                ------------------------------------------------
                     Amendment and Termination of the Plan
                     -------------------------------------

     7.1  Adoption of the Plan by Affiliate.  An Affiliate may adopt the Plan
          ---------------------------------                                    
by appropriate action of its board of directors or authorized officers or
representatives, subject to the approval of the Board.

     7.2  Amendment and Termination.  The Company hereby reserves the right to
          -------------------------                                            
amend, modify, or terminate the Plan at any time, and for any reason, by written
resolution of the Board.  However, no amendment or termination shall have the
effect of reducing the benefits accrued by a Participant prior to the date of
the amendment or termination.

                    Article VIII.  Miscellaneous Provisions
                    ---------------------------------------

     8.1  No Contract of Employment.  Nothing contained in the Plan shall be
          -------------------------                                          
construed to give any Participant the right to be retained in the service of the
Company or its Affiliates or to interfere with the right of the Company or its
Affiliates to discharge a Participant at any time.

     8.2  Severability.  If any provision of this Plan shall be held illegal
          ------------                                                        
or invalid, the illegality or invalidity shall not affect its remaining parts.
The Plan shall be construed and enforced as if it did not contain the illegal or
invalid provision.

     8.3  Applicable Law.  Except to the extent preempted by applicable federal
          --------------                                                        
law, this Plan shall be governed by and construed in accordance with the laws of
the state of Georgia.

The following information pertains to options to purchase shares of common
stock which were not included in the computation of Diluted Earnings per
Common Share because the options' exercise price was greater than the average
market price of the common shares or because the Company reported a net loss
and inclusion of the options in the earnings per share calculation would have
been anti-dilutive:

                             CAUTIONARY STATEMENTS
 
        From time to time, the Company may publish, verbally or in written
form, forward-looking statements relating to such matters as anticipated
financial performance, business prospects, technological developments, new
products, research and development activities and similar matters. In fact,
this Form 10-K (or any other periodic reporting documents required by the 1934
Act) may contain forward-looking statements reflecting the current views of
the Company concerning potential future events or developments. The Private
Securities Litigation Reform Act of 1995 (the "Act") provides a "safe harbor"
for forward-looking statements. These Cautionary Statements are being made
pursuant to the provisions of the Act and with the intention of obtaining the
benefits of the "safe harbor" provisions of the Act. In order to comply with
the terms of the "safe harbor," the Company cautions investors that any
forward-looking statements made by the Company are not guarantees of future
performance and that a variety of factors could cause the Company's actual
results and experience to differ materially from the anticipated results or
other expectations expressed in the Company's forward-looking statements. The
risks and uncertainties which may affect the operations, performance,
development and results of the Company's business include, but are not limited
to, the following: uncertainties relating to the development and ownership of
intellectual property; uncertainties relating to the ability of the Company
and other companies to enforce their intellectual property rights;
uncertainties relating to economic conditions (including, but not limited to,
the continued weak economic conditions in the Asia Pacific region);
uncertainties relating to government and regulatory policies; uncertainties
relating to customer plans and commitments; the Company's dependence on the
cable television industry and cable television spending; signal security; the
pricing and availability of equipment, materials and inventories;
technological developments; performance issues with key suppliers and
subcontractors; governmental export and import policies; global trade
policies; worldwide political stability and economic growth; regulatory
uncertainties; delays in development of new products, including digital set-
top products and the applications to be used on such digital set-top products;
delays in testing of new products; rapid technology changes; the highly
competitive environment in which the Company operates; the entry of new, well-
capitalized competitors into the Company's markets; reliance on software
programs used by the Company or its suppliers containing problems related to
computations that must be made in 1999, 2000, and beyond ("Year 2000
Problems") and Year 2000 Problems that may exist in products currently or
historically sold to customers of the Company; changes in the financial
markets relating to the Company's capital structure and cost of capital; and
uncertainties inherent in international operations and foreign currency
fluctuations. The words "believe," "expect," "anticipate," "project," "plan"
and similar expressions identify forward-looking statements. Readers are
cautioned not to place undue reliance on these forward-looking statements,
which speak only as of the date the statement was made.
