NOTES:
(Amounts in thousands, except share data).


     A.   The accompanying consolidated financial statements include the
          accounts of the company and all subsidiaries after elimination of all
          material intercompany accounts and transactions. Certain information
          and footnote disclosures normally included in financial statements
          prepared in accordance with generally accepted accounting principles
          have been condensed or omitted pursuant to the rules and regulations
          of the Securities and Exchange Commission. These condensed financial
          statements should be read in conjunction with the consolidated
          financial statements and related notes contained in the company's 1998
          Form 10-K. The financial information presented in the accompanying
          statements reflects all adjustments which are, in the opinion of
          management, necessary for a fair presentation of the periods
          indicated. All such adjustments are of a normal recurring nature.

     B.   The company's fiscal year ends on the Friday closest to June 30 of
          each year. Fiscal 1999 includes fifty-three weeks. The three and nine
          months ended April 2, 1999 include thirteen and forty weeks,
          respectively.

     C.   Basic earnings per share were computed based on the weighted average
          number of shares outstanding. Diluted earnings per share were computed
          based on the weighted average number of dilutive shares of common
          stock outstanding. See Exhibit 11.

     D.   Other (income) expense for the quarter ended April 2, 1999 included a
          gain of $1,375 from the adjustment of the company's investment in
          Broadcom Corp (Broadcom) to market value as required by generally
          accepted accounting principles.

          Other (income) expense for the nine months ended April 2, 1999
          included a $39,750 gain from the adjustment of the company's
          investment in Broadcom to market value, a $10,880 loss on the sale of
          one million shares of the company's investment in Broadcom, and a gain
          of $6,250 from the cancellation of a contract under which the company
          was obligated to supply equipment which, upon resale, the company had
          estimated losses would be incurred. In addition, during the nine
          months ended April 2, 1999, the company decided to dispose of a
          business unit, Control Systems, which produces devices to monitor and
          manage utility service usage, because the business unit did not fit
          with the company's core strategy. The company recorded a charge of
          $6,225 to adjust the carrying value of the assets to be sold to fair
          value, less costs to sell, to adjust the estimated profitability on
          certain contracts to allow the purchaser to achieve reasonable
          margins, to provide for indemnification to the purchaser and to
          provide for other miscellaneous expenses associated with the sale.
          There have been no charges to the reserve through April 2, 1999. The
          company anticipates completing the sale of Control Systems during the
          first half of fiscal 2000.

          Other (income) expense for the quarter ended March 27, 1998 included a
          gain from the sale of certain assets of the interdiction business unit
          and charges from the discontinuance of development of coaxiom systems.

          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 $19,000 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 approximately $9,080. At April 2,
          1999, the company had a reserve of approximately $3,618 for 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 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 $9,000. The charge
          related to 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. At April 2, 1999, the company had disposed of the fixed
          assets and anticipates disposal of the inventory by the end of the
          1999 fiscal year. The company had a reserve of approximately $1,030
          related to the discontinuance of coaxiom products at April 2, 1999.
          The company will continue to develop applications and technology for
          telephony on cable using IP (Internet protocol) telephony which will
          be used in the company's networks and Explorer(R) 2000 digital
          interactive set-tops.

          There were no other significant items in other (income) expense for
          the three and nine months ended March 27, 1998.

          Other (income) expense for the three and nine months ended April 2,
          1999 and March 27, 1998 also included the results of foreign currency
          transactions and partnership activities and net gains from rental
          income and other miscellaneous items.

     E.   Inventories consist of the following:     April 2,          June 26,

     F.   During fiscal 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 pre-tax
          charge of $5,526. During the nine months ended March 27, 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 April 2, 1999, the company had a reserve of
          approximately $3,428 to adjust the carrying amount of the net assets
          of the mobile business unit and for potential losses on contracts of
          the microwave business which were retained by the company, severance
          costs, and other miscellaneous expenses related to the sale of the
          microwave business unit. The company anticipates disposal of the net
          assets of the mobile business by the end of this fiscal year.

     G.   During the nine months ended April 2, 1999, the company acquired
          4,648,000 shares of its common stock pursuant to a stock buyback
          program for an aggregate cost of $65,228 and acquired an additional
          75,880 shares from the payment in stock rather than cash by employees
          of tax withholdings on restricted stock which vested and the
          cancellation of unvested, restricted stock. During the nine months
          ended March 27, 1998, the company purchased 500,000 shares of its
          common for an aggregate cost of $7,511. The company obtained an
          additional 73,240 shares of its common stock, primarily from the
          cancellation of unvested, restricted stock grants. The company re-
          issues these shares under the company's stock option plans, 401(k)
          plan, employee stock purchase plan and other stock-based employee
          compensation arrangements.

     H.   The company adopted Statement of Financial Accounting Standards (SFAS)
          No. 130, "Reporting Comprehensive Income" in fiscal 1999. SFAS No. 130
          requires the reporting of a measure of all changes in equity of an
          entity that result from recognized transactions and other economic
          events other than transactions with owners in their capacity as
          owners. Other comprehensive income (loss) for each period presented
          includes only foreign currency translation adjustments. The
          calculation of comprehensive income is as follows:

     I.   During the fourth quarter of fiscal 1999, the company sold its
          remaining one million share investment in Broadcom and realized a gain
          of $12,459. The company also exercised warrants during the fourth
          quarter of fiscal 1999 to purchase 720,000 shares of common stock of
          Harmonic Inc. simultaneously sold the 720,000 shares of Harmonic
          Inc. and realized a gain of $16,646.

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


FINANCIAL CONDITION
- -------------------

     Scientific-Atlanta had stockholders' equity of $660.0 million and cash on
hand was $174.6 million at April 2, 1999. Cash decreased $0.8 million from June
26, 1998 as expenditures for the acquisition of shares of the company's common
stock, increases in inventory levels and accounts receivable and expenditures
for equipment exceeded proceeds from the sale of marketable securities and cash
generated from earnings, increases in payables and the issuance of common stock.
The current ratio was 2.8:1 at April 2, 1999, approximately the same as June 26,
1998. At April 2, 1999, total debt was $1.5 million or less than one percent of
total capital invested. 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
in the company's Juarez, Mexico facility.

RESULTS OF OPERATIONS
- ---------------------

     Sales for the quarter ended April 2, 1999, were $320.0 million, up 11
percent over the prior year. Strong North American sales growth in Transmission
Network Systems' and Subscriber Systems' products and services were offset in
part by declines in sales of Satellite products. The growth in Transmission
Network Systems was driven by the North American rebuild cycle. The significant
increase in sales of digital products was the primary factor in the year-to-year
increase in Subscriber Systems. Satellite sales declined in fiscal 1999 as this
sector, which relies significantly on international markets, continues to be
impacted by the weak economic conditions in Eastern Europe and the Asia Pacific
region. International sales were 22 percent of total sales in the quarter ended
April 2, 1999 as compared to 25 percent of total sales for the same quarter last
year.

     Sales for the nine months ended April 2, 1999 were $888.2 million, up
slightly over the prior year. The strong growth in North American sales of
Transmission Network Systems' and Subscriber Systems' products described in the
preceding paragraph was offset partially by continued weak economic conditions
in the Asia Pacific, Eastern Europe and Latin American regions, which negatively
impacted Satellite sales. International sales were 22 percent of total sales in
the nine months ended April 2, 1999 as compared to 35 percent of total sales
last year.

     As anticipated and announced previously, sales of analog set-tops declined
in response to the introduction of two-way digital technology. The company
expected a decline in analog sales as cable operators establish the ideal mix of
analog and digital services in each cable system.

     The GainMaker(TM) product was previously announced as being available for 
purchase in the third fiscal quarter of 1999, but such product is now expected 
to be available for purchase in the fourth fiscal quarter of 1999.

     Gross margins were 28.6 percent and 28.1 percent for the three and nine
months ended April 2, 1999, 3.0 percentage points and 2.4 percentage points
lower than the comparable periods of the prior year. Margins on digital set-
tops, which were lower than the company average, offset gains from cost
reductions from the transfer of RF (radio frequency) production to Juarez,
Mexico from Norcross, Georgia.

     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. The company has forward exchange contracts to
purchase yen to hedge a portion of its exposure on purchase commitments for a
period of approximately twelve months.

     Increases in operating expenses relative to last year are due in part to
the fact that the nine months ended April 2, 1999 included forty weeks, as
compared to the normal thirty-nine week period in the prior year.

     Research and development expenses were $27.9 million and $87.0 million for
the three and nine months ended April 2, 1999, respectively, reflecting the
company's continued investment in research and development programs to support
new product initiatives, particularly digital products. The company capitalized
software development costs of $1.0 million and $2.4 million during the three and
nine months ended April 2, 1999, respectively. There were no non-recurring
engineering costs capitalized during the nine months ended April 2, 1999. During
the three and nine months ended March 27, 1998, the company capitalized software
development costs of $0.4 million and $1.8 million and capitalized non-recurring
engineering costs of $6.2 million during the nine months ended March 27, 1998.
Research and development spending, including capitalized software development
costs and non-recurring engineering, was approximately $30 million in each of
the three month periods ended April 2, 1999 and March 27, 1998 and
approximately $90 million in each of the nine month periods ended April 2, 1999
and March 27, 1998.

                                    7 of 12
<PAGE>
 
     Sales and administrative expenses were $2.2 million lower in the three
months ended April 2, 1999 as compared to the same quarter of the prior year due
primarily to the benefits realized in the third quarter of fiscal 1999 from the
previously announced re-sizing of the Satellite businesses. These lower expenses
were offset partially by increased marketing efforts related to digital video
products and Prisma(TM) Digital Transport products. Sales and administrative
expenses for the nine months ended April 2, 1999 were flat as compared to the
prior year. Benefits from the re-sizing of the Satellite businesses were offset
by increased marketing efforts related to digital video products and Prisma
Digital Transport products and an additional week in the nine month period ended
April 2, 1999 as compared to the prior year.

     Other (income) expense for the quarter ended April 2, 1999 included a gain
of $1.4 million from the adjustment of the company's investment in Broadcom Corp
(Broadcom) to market value as required by generally accepted accounting
principles.

     Other (income) expense for the nine months ended April 2, 1999 included a
$39.7 million gain from the adjustment of the company's investment in Broadcom
to market value, a $10.9 million loss on the sale of one million shares of the
company's investment in Broadcom, and a gain of $6.2 million from the
cancellation of a contract under which the company was obligated to supply
equipment which, upon resale, the company had estimated losses would be
incurred. In addition, during the nine months ended April 2, 1999, the company
decided to dispose of a business unit, Control Systems, which produces devices
to monitor and manage utility service usage, because the business unit did not
fit with the company's core strategy. The company recorded a charge of $6.2
million to adjust the carrying value of the assets to be sold to fair value,
less costs to sell, to adjust the estimated profitability on certain contracts
to allow the purchaser to achieve reasonable margins, to provide for
indemnification to the purchaser and to provide for other miscellaneous expenses
associated with the sale. There have been no charges to the reserve through
April 2, 1999. The company anticipates completing the sale of Control Systems
during the first half of fiscal 2000.

     Other (income) expense for the quarter ended March 27, 1998 included a gain
from the sale of certain assets of the interdiction business unit and charges
from the discontinuance of development of coaxiom systems.

     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 cash,
Blonder Tongue stock valued at $1.0 million and an option to acquire additional
shares of Blonder Tongue stock, and the company recorded a pre-tax gain of
approximately $9.1 million. At April 2, 1999, the company had a reserve of
approximately $3.6 million for 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 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 charge of approximately $9.0
million. The charge related to 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.
At April 2, 1999, the company had disposed of the fixed assets and anticipates
disposal of the inventory by the end of the fiscal year. The company had a
reserve balance of approximately $1.0 million related to the discontinuance of
coaxiom products at April 2, 1999. The company will continue to develop
applications and technology for telephony on cable using IP (Internet protocol)
telephony which will be used in the company's networks and Explorer(R) 2000
digital interactive set-tops.

     There were no other significant items in other (income) expense for the
three and nine months ended March 27, 1998.

     Other (income) expense for the three and nine months ended April 2, 1999
and March 27, 1998 also included the results of foreign currency transactions
and partnership activities and net gains from rental income and other
miscellaneous items.

     During fiscal 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 pre-tax charge of $5.5
million. During the nine months ended March 27, 1998, 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. At April 2, 1999, the
company had a reserve of approximately $3.4 million to adjust the carrying
amount of the net assets of the mobile business unit and for potential losses on
contracts of the microwave business which were retained by the company,
severance, and other miscellaneous expenses related to the sale of the microwave
business unit. The company anticipates disposal of the net assets of the mobile
business by the end of this fiscal year.

     In the fourth quarter of fiscal 1998, the company recorded charges of $23.4
million in connection with a restructuring plan. These charges included $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 $4.8 million for impairment of
certain assets and other miscellaneous expenses. The company began
implementation of the restructuring plan during fiscal 1998. The company
incurred severance costs of $1.0 million and other miscellaneous expenses of
$0.2 million related to the restructuring plan which were charged to the reserve
in the fourth quarter of fiscal 1998.

     During fiscal 1999, the company continued the implementation of its
restructuring plan. Production of the RF amplifier was transferred to the
company's high volume, low cost manufacturing facility in Juarez, Mexico from
Norcross, Georgia; the consolidation of the production of headend equipment from
Vancouver, British Columbia to Norcross, Georgia was substantially completed.
The Melbourne, Florida satellite services Network Operations Center (NOC) and
research and development facility were relocated to Norcross, Georgia; Satellite
Networks and Communications and Tracking Systems business units were combined
and re-sized downward, and the consolidation of operations in Norcross, Georgia
was substantially completed. During fiscal 1999, the company incurred expenses
of $0.7 million related to the cancellation of leases, severance costs of $3.0
million, and $1.4 million of miscellaneous expenses related to the
implementation of its restructuring plan. These expenses were charged to the
restructuring reserves recorded in the fourth quarter of fiscal 1998. The
company had a balance of $4.7 million related to the restructuring plan at April
2, 1999. The company anticipates that the restructuring plan will be
substantially completed by the end of fiscal 1999.

     The company's effective income tax rate was 30 percent for the quarter and
nine months, unchanged from the prior year.

     Net earnings for the three months ended April 2, 1999 were $20.8 million,
up $3.7 million over the prior year. Higher sales volume and lower operating
expenses year-over-year were offset in part by lower gross margins on digital
products. Net earnings for the nine months ended April 2, 1999 were $55.0
million, up $6.5 million over the prior year. An after-tax gain of $20.2 million
from the company's investment in Broadcom was partially offset by lower gross
margin rates and increased operating expenses.

YEAR 2000
- ---------

     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
compliant 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 systems 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 commenced testing of its IT systems and Non-IT systems in the
first calendar quarter of 1999. To date, such testing has not revealed any 
significant Year 2000 issues.

     Certain products currently sold by the company contain computer programs
that perform date functions or date calculations. The company has evaluated its
products and is continuing to evaluate its products, and, based on its
investigation to date, the company believes that the products it currently sells
(except third party software included in the company's digital network control
system) are Year 2000

                                    9 of 12
<PAGE>
 
compliant, provided that they are upgraded to include all recommended and
available 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 company in prior years. 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 (and higher versions) software 
which is currently available for purchase. Additionally, the company is actively
working with its third party software provider to remedy the Year 2000 issues in
the software included in the company's digital network control system. Such
System Release 4.6 (and higher versions) 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 and
related equipment to System Release 4.6 (or higher version) software and related
equipment may result in such customer having critical Year 2000 problems. Under
certain limited circumstances, the company may incur expense to help 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 expects the costs related to remediating Year 2000 issues not
to be material. 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 scenarios and contingency planning related thereto. Phase
II is almost completed and is expected to be totally completed during the second
calendar quarter of 1999. 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 is under way and is expected to be
completed in the second or third calendar quarter of 1999. Last, Phase IV
involves implementation of the company's contingency plans. Several contingency
plans are currently being implemented and will continue to be implemented
through the remainder of calendar year 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 software releases related to either the System Manager upgrades or the
upgrade of the third party software included in the digital network control
system) 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.

ITEM 3.   QUANTITIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS
- -------   --------------------------------------------------------- 

     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 through
April 2, 2000 are as follows:

                                          Japanese          Canadian

                             SHAREHOLDERS' MEETINGS
                             ----------------------


     Section 1.   Annual Meetings. The annual meeting of the shareholders of the
                  ---------------                                               
corporation shall be held at such place and time in the United States as may be
determined by the board of directors, for the purpose of electing directors and
transacting such other business as may properly be brought before the meeting.
To be properly brought before the meeting, business must be either (a) specified
in the notice of meeting (or any supplement thereto) given by or at the
direction of the board of directors, (b) otherwise properly brought before the
meeting by or at the direction of the board of directors, or (c) otherwise
properly brought before the meeting by a shareholder. In addition to any other
applicable requirements, for business to be properly brought before an annual
meeting by a shareholder, the shareholder must have given timely notice thereof
in writing to the Secretary of the corporation. To be timely, a shareholder's
notice must be delivered to or mailed and received at the principal executive
offices of the corporation, no earlier than 90 days and no later than 60 days
prior to the date of such meeting, regardless of any postponements, deferrals or
adjournments of such meeting to a later date; provided, however, that if less
than 70 days' notice or prior public disclosure of the date of the meeting is
given or made, notice by a holder of record must, to be timely, be so delivered
or received not later than the close of business on the tenth day following the
day on which such notice of the date of the meeting is mailed or the day on
which such public disclosure was made; provided that, in the case of an annual
meeting, notice by a holder of record, to be timely, must be so delivered or
received not later than the close of business 60 days prior to the anniversary
of the date of the previous year's annual meeting.  A shareholder's notice to
the Secretary shall set forth as to each matter the shareholder proposes to
bring before the annual meeting (i) a brief 

                                       1
<PAGE>
 
description of the business desired to be brought before the annual meeting and
the reasons for conducting such business at the annual meeting, (ii) the name
and record address of the shareholder proposing such business, (iii) the class
and number of securities of the corporation which are beneficially owned by the
shareholder, and (iv) any material interest of the shareholder in such business.

     Notwithstanding anything in the By-Laws to the contrary, no business shall
be conducted at the annual meeting except in accordance with the procedures set
forth in this Section 1, provided, however, that nothing in this Section 1 shall
                         --------  -------                                      
be deemed to preclude discussion by any shareholder of any business properly
brought before the annual meeting.

     The presiding officer at an annual meeting shall, if the facts warrant,
determine and declare to the meeting that business was not properly brought
before the meeting in accordance with the provisions of this Section 1, and if
he should so determine, he shall so declare to the meeting and any such business
not properly brought before the meeting shall not be transacted.

     Section 2.   Special Meetings. (a) Special meetings of the shareholders
                  ----------------                                          
shall be held at the principal office of the corporation or at such other place
in the United States as may be designated in the notice of such meetings, and
shall be called by the chief executive officer or the secretary only when so
directed by the board of directors or when so requested in writing by the
holders of at least 75 percent of the issued and outstanding capital stock of
the corporation entitled to vote in an election of directors.

          (b)  Anything in these by-laws to the contrary notwithstanding, the
     following procedures shall apply to the call of any special meeting of
     shareholders, or a special meeting in lieu of the annual meeting of
     shareholders, at the request of holders of the outstanding capital stock of
     the corporation:

               (i)   Every written request for the call of a special meeting
               shall bear the signature and date of signature of each
               shareholder who signs the request and shall state the purpose or
               purposes for which the meeting is to be called.

               (ii)  The record date for the determination of shareholders
               entitled to request the corporation to call a special meeting
               shall be the date which is 45 calendar days prior to the date
               (the "Filing Date") that written requests complying with the
               requirements of law and these by-laws signed by a sufficient
               number of record holders to request a special meeting in
               accordance with this Section 2 have been received by the
               corporation (the "Minimum Request Condition").

               (iii) Promptly after receipt of a written request or requests for
               the call of a special meeting, the corporation shall engage
               nationally recognized independent inspectors of election for the
               purpose of determining the validity of the request or requests
               and any revocations thereof. Within 15

                                       2
<PAGE>
 
               calendar days of the Filing Date, such independent inspectors
               shall deliver to the corporation a written report stating whether
               the Minimum Request Condition has been satisfied. If such written
               report states that the Minimum Request Condition has been
               satisfied, or if no report is delivered by independent inspectors
               within 15 calendar days of the Filing Date, the chief executive
               officer or the secretary of the corporation shall call the
               special meeting by mailing notice thereof not later than 45
               calendar days after the Filing Date.

               (iv)  The date, time and place of the special meeting shall be
               determined by the board of directors and shall be set forth in
               the notice of meeting, which notice shall comply with the
               provisions of Section 3 of this Article II.

               (v)   The record date for the determination of shareholders
               entitled to notice of and to vote at the special meeting shall be
               set by the board of directors in accordance with the provisions
               of Section 4 of Article V of these by-laws.

     Section 3.   Notice of Meetings. Written notice of every meeting of
                  ------------------                                    
shareholders, stating the place, date and hour of the meeting, shall be given
personally or by mail to each shareholder of record entitled to vote at such
meeting not less than 10 nor more than 60 days before the date of the meeting.
If mailed, such notice shall be deemed to be delivered when deposited in the
United States mail with first class postage thereon prepaid (except as
hereinafter provided) addressed to the shareholder at his address as it appears
on the corporation's record of stockholders. The corporation may utilize a class
of mail other than first class if the notice of the meeting is mailed, with
adequate postage prepaid, not less than 30 days before the date of the meeting.
Attendance of a shareholder at a meeting of shareholders (1) waives objection to
lack of notice or defective notice of the meeting, unless the shareholder at the
beginning of the meeting objects to holding the meeting or transacting business
at the meeting, and (2) waives objection to consideration of a particular matter
at the meeting that is not within the purpose or purposes described in the
meeting notice, unless the shareholder objects to considering the matter when it
is presented. Notice need not be given to any shareholder who signs a waiver of
notice either before or after the meeting.

     Section 4.   Quorum. The holders of a majority of the stock issued and
                  ------                                                   
outstanding and entitled to vote thereat, present in person or represented by
proxy, shall constitute a quorum for the transaction of business at all meetings
of the shareholders except as otherwise provided by statute, by the articles of
incorporation, or by these by-laws. If a quorum is not present or represented at
any meeting of the shareholders, the holders of a majority of the voting shares,
present in person or represented by proxy, may adjourn the meeting from time to
time, without notice other than announcement at the meeting, until a quorum
shall be present or represented. At such adjourned meeting at which a quorum
shall be present or represented, any business may be transacted which might have
been transacted at the meeting as originally notified. If the adjournment is for
more than 120 days, or if a new record date is fixed for the adjourned meeting,
a notice of the adjourned meeting shall be given to each shareholder of record
entitled 

                                       3
<PAGE>
 
to vote at the meeting.

     Section 5.   Voting. When a quorum is present at any meeting, action on a
                  ------                                                      
matter (other than the election of directors) is approved if the votes cast
favoring the action exceed the votes cast opposing the action, unless the
question is one upon which by express provision of law, of the articles of
incorporation or of these by-laws, a different vote is required, in which case
such express provision shall govern and control the decision of the question.
Except as otherwise required by the Articles of Incorporation, each shareholder
shall at every meeting of the shareholders be entitled to one vote in person or
by proxy for each share of the capital stock having voting power registered in
his name on the books of the corporation, but no proxy shall be voted or acted
upon after eleven months from its date, unless otherwise provided in the proxy.

     Section 6.   Consent of Shareholders. Any action required or permitted to
                  -----------------------                                     
be taken at any meeting of the shareholders may be taken without a meeting if
all of the shareholders consent thereto in writing, setting forth the action so
taken, and such writing is delivered to the corporation for inclusion in the
minutes or filing with the corporate records. Such consent shall have the same
force and effect as a unanimous vote of shareholders.

     Section 7.   List of Shareholders. The corporation shall keep at its
                  --------------------                                   
registered office or principal place of business, or at the office of its
transfer agent or registrar, a record of its shareholders, giving their names
and addresses and the number, class and series, if any, of the shares held by
each. The officer who has charge of the stock transfer books of the corporation
shall prepare and make, before every meeting of shareholders or any adjournment
thereof, a complete list of the shareholders entitled to vote at the meeting or
any adjournment thereof, arranged in alphabetical order, with the address of and
the number and class and series, if any, of shares held by each. The list shall
be produced and kept open at the time and place of the meeting and shall be
subject to inspection by any shareholder during the whole time of the meeting
for the purposes thereof. The said list may be the corporation's regular record
of shareholders if it is arranged in alphabetical order or contains an
alphabetical index.

                                  ARTICLE III

                                   DIRECTORS
                                   ---------

     Section 1.   Powers. Except as otherwise provided or authorized by law, the
                  ------                                                        
property, affairs and business of the corporation shall be managed and directed
by its board of directors, which may exercise all powers of the corporation and
do all lawful acts and things which are not by law, by any legal agreement among
shareholders or by the articles of incorporation, directed or required to be
exercised or done by the shareholders.

     Section 2.   Meetings and Notice. The board of directors of the corporation
                  -------------------                                           
may hold meetings, both regular and special, either within or without the state
of Georgia. Regular meetings of the board of directors may be held without
notice at such time and place as shall from time to time be determined by
resolution of the board. Special meetings of the board may be called by the
chairman of the board or the chief executive officer or by any three directors
on 

                                       4
<PAGE>
 
one day's oral, telegraphic or written notice duly given or served on each
director personally, or three days' notice deposited, first class postage
prepaid, in the United States mail. Such notice shall state a reasonable time,
date and place of meeting, but the purpose need not be stated therein. Notice
need not be given to any director who signs a waiver of notice either before or
after the meeting. Attendance of a director at a meeting shall constitute a
waiver of notice of such meeting and waiver of all objections to the place and
time of the meeting, or the manner in which it has been called or convened,
except when the director states, at the beginning of the meeting, any such
objection or objections to the transaction of business.

     Section 3.   Quorum. At all meetings of the board a majority of directors
                  ------                                                      
shall constitute a quorum for the transaction of business, and the act of a
majority of the directors present at any meeting at which there is a quorum
shall be the act of the board, except as may be otherwise specifically provided
by law, by the articles of incorporation, or by these by-laws. If a quorum shall
not be present at any meeting of the board, a majority of the directors present
thereat may adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall be present.

     Section 4.   Consent of Directors. Unless otherwise restricted by the
                  --------------------                                    
articles of incorporation or these by-laws, any action required or permitted to
be taken at any meeting of the board of directors or of any committee thereof
may be taken without a meeting, if all members of the board or committee, as the
case may be, consent thereto in writing, setting forth the action so taken, and
the writing or writings are delivered to the corporation for inclusion in the
minutes of the proceedings of the board or committee or filing with the
corporate records. Such consent shall have the same force and effect as a
unanimous vote of the board.

     Section 5.   Committees. The board of directors may by resolution designate
                  ----------                                                    
from among its members one or more committees, each committee to consist of one
or more directors. The board may designate one or more directors as alternate
members of any committee, who may replace any absent member at any meeting of
such committee. Any such committee, to the extent provided in the resolution,
shall have and may exercise all of the authority of the board of directors in
the management of the business and affairs of the corporation, except that it
shall have no authority to (1) approve or propose to shareholders action which
the Georgia Business Corporation Code requires to be approved by shareholders;
(2) fill vacancies on the board of directors or any of its committees; (3) amend
the articles of incorporation; (4) adopt, amend or repeal by-laws; or (5)
approve a plan of merger not requiring shareholder approval. Such committee or
committees shall have such name or names as may be determined from time to time
by resolution adopted by the board of directors. The provisions of Sections 2
and 3 of this Article III shall apply to committees and their members as well as

                  ------------------------                               
election at any meeting of the shareholders of the corporation as directors of
the corporation may be made (i) by, or at the direction of, the board of
directors or (ii) by any holder of record entitled to vote at such meeting in an
election of directors who complies with the notice procedures set forth in this
Section 7.

     Nominations, other than those made by, or at the direction of, the board of
directors, shall be made pursuant to timely notice in writing to the secretary
of the corporation as set forth in this Section 7. To be timely, any such notice
must be delivered to, or mailed and received at, the principal executive offices
of the corporation not less than 60 days nor more than 90 days prior to the date
of such meeting, regardless of any postponements, deferrals or adjournments of
such meeting to a later date; provided, however, that if less than 70 days'
notice or prior public disclosure of the date of the meeting is given or made,
notice by a holder of record must, to be timely, be so delivered or received not
later than the close of business on the tenth day following the day on which
such notice of the date of the meeting is mailed or the day on which such public
disclosure was made; provided that, in the case of an annual meeting, notice by
a holder of record, to be timely, must be so delivered or received not later
than the close of business 60 days prior to the anniversary of the date of the
previous year's annual meeting.  Such notice by a holder of record must set
forth (i) as to each person whom such holder proposes to nominate for election
as a director, all information relating to such person that would be required to
be disclosed, or otherwise required, pursuant to Sections 13 or 14 of the
Securities Exchange Act of 1934, as amended, and the rules and regulations
promulgated thereunder (the "Exchange Act"), in connection with any acquisition
of shares and the solicitations of proxies with respect to nominees for election
of directors pursuant to the Exchange Act, regardless of whether such person is
subject to such provisions of such Exchange Act, and (ii) as to the holder of
record giving such notice, (a) the name and address, as they appear on the
records of the corporation, of such holder, together with the name and address
of any other shareholder of the corporation who is a record or beneficial owner
of securities of the corporation and who is known by such holder to be
supporting such nominee(s) and (b) the class and number of securities which are
beneficially owned and owned of record by such holder on the date of such
holder's notice and the class and number of securities of the corporation
beneficially owned and owned of record by any person known by such holder to be
supporting such nominee(s). At the request of the board of directors, any person
nominated by, or at the direction of, the board of directors for election as a
director shall furnish to the secretary of the corporation that information that
would be required to be set forth in any holder's notice of nomination
pertaining to such nominee. Ballots bearing the names of all the persons who
have been nominated for election as directors at any meeting of shareholders in
accordance with the procedures set forth in this Section 7 shall be provided for
use at such meeting.

     The board of directors of the corporation may reject any nomination by a
holder of record not timely made in accordance with the procedures set forth in
this Section 7. If the board of directors determines that the information
provided in a holder's notice of nomination does not 

                                       6
<PAGE>
 
satisfy the informational requirements of this Section 7 in any material
respect, the secretary of the corporation shall promptly notify such holder of
the deficiency in such notice. The holder shall have an opportunity to cure the
deficiency by providing additional information to the secretary within such
period of time, not to exceed five days, from the date such notice of deficiency
is given to such holder, as the board of directors shall determine. If the
deficiency is not cured within such period, or if the board of directors
reasonably determines that the additional information provided by such holder,
together with previously provided information, does not satisfy the requirements
of this Section 7 in any material respect, then the board of directors may
reject such holder's nomination. The secretary of the corporation shall notify
in writing any holder making a nomination whether such nomination has been made
in accordance with the time and informational requirements of this Section 7.
Notwithstanding the procedures set forth herein, if the board of directors does
not make a determination as to the validity of any nomination by a holder of
record, the presiding officer at the meeting of shareholders shall determine and
declare at such meeting whether a nomination was or was not made in accordance
with the procedures set forth in this Section 7. If the presiding officer
determines that a nomination was not made in accordance with the procedures set
forth in this Section 7, he shall so declare at such meeting of shareholders and
the defective nomination shall be disregarded.

                                  ARTICLE VII

                                INDEMNIFICATION
                                ---------------

     Section 1.   Definitions. As used in this Article, the term
                  -----------                                   

          (a)  "change of control", for purposes of this Article VII, means (1)
     an acquisition by a person of beneficial ownership of 20% or more of the
     combined voting power of the corporation's then outstanding voting
     securities, provided that any such securities acquired directly from the
     corporation shall be excluded from the determination of such person's
     beneficial ownership (but shall be included in calculating total
     outstanding securities); or (2) the individuals who are members of the
     incumbent board (as defined below) cease for any reason to constitute two-
     thirds of the Board of Directors; or (3) approval by the shareholders of
     the corporation of (i) a merger or consolidation involving the corporation
     if the shareholders of the corporation, immediately before such merger or
     consolidation, do not own, immediately following such merger or
     consolidation, more than 80% of the combined voting power of the
     outstanding voting securities of the corporation in substantially the same
     proportion as their ownership of voting securities immediately before such
     merger or consolidation or (ii) a complete liquidation or dissolution of
     the corporation or an agreement for the sale or other disposition of all or
     substantially all of the assets of the corporation.

          Notwithstanding the foregoing, a change of 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 corporation or any of its subsidiaries or (ii) any
     corporation which, immediately prior to such acquisition, is owned directly
     or indirectly by the shareholders of this corporation in the same
     proportion as their ownership of shares in this corporation immediately
     prior to such acquisition.

          Moreover, notwithstanding the foregoing, a change of 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 corporation 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 of
                                               --------                     
     control would occur (but for 

                                       13
<PAGE>
 
     the operation of this sentence) as a result of the acquisition of voting
     securities by the corporation, and after such share acquisition by the
     corporation, 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 of control shall occur.

          (b)  "corporation" includes any domestic or foreign predecessor entity
     of the corporation or a corporation in a merger or other transaction in
     which the predecessor's existence ceased upon consummation of the
     transaction.

          (c)  "director" means an individual who is or was a director of the
     corporation or an individual who, while a director of the corporation, is
     or was serving at the corporation's request as a director, officer,
     partner, trustee, employee, or agent of another foreign or domestic
     corporation, partnership, joint venture, trust, employee benefit plan, or
     other enterprise. A director is considered to be serving an employee
     benefit plan at the corporation's request if his duties to the corporation
     also impose duties on, or otherwise involve services by, him to the plan or
     to participants in or beneficiaries of the plan. Director includes, unless
     the context requires otherwise, the estate or personal representative of a
     director.

          (d)  "expenses" include attorneys' fees.

          (e)  "incumbent board" includes the individuals who as of May 11, 1994
     are members of the Board of Directors and any individual becoming a
     director subsequent to May 11, 1994 whose election, or nomination for
     election by the corporation's shareholders 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 of Directors
     shall become a member of the incumbent board upon the completion of two
     full years as a member of the Board of Directors; provided further,
                                                       -------- ------- 
     however, that notwithstanding the foregoing, no individual shall be
     -------                                                            
     considered a member of the incumbent board if such individual initially
     assumed office (1) as a result of either an actual 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 of Directors (a "Proxy Contest") or
     (2) with the approval of the other members of the Board of Directors, but
     by reason of any agreement intended to avoid or settle a Proxy Contest.

          (f)  "liability" means the obligation to pay a judgment, settlement,
     penalty, fine (including an excise tax assessed with respect to an employee
     benefit plan), or reasonable expenses incurred with respect to a
     proceeding.

          (g)  "party" includes an individual who was, is, or is threatened to
     be made a named defendant or respondent in a proceeding.

                                       14

          (h)  "proceeding" means any threatened, pending, or completed action,
     suit, or proceeding, whether civil, criminal, administrative, or
     investigative and whether formal or informal.



     Section 2.   Indemnification of Directors, Officers and Employees -
                  ------------------------------------------------------
General.

          (a)  Subject to the terms and conditions of this Article VII, the
     corporation shall indemnify an individual made a party to a proceeding
     because he is or was a director or officer of the corporation against
     liability incurred in connection with a proceeding to the fullest extent
     permitted by the Georgia Business Corporation Code (the "GBCC"), as the
     same now exists or may hereafter be amended (but only to the extent any
     such amendment permits the corporation to provide broader indemnification
     rights than the GBCC permitted the corporation to provide prior to such
     amendment).

          (b)  The termination of a proceeding by judgment, order, settlement,
     or conviction, or upon a plea of nolo contendere or its equivalent is not,
     of itself, determinative that the director or officer did not meet the
     standard of conduct set forth in the GBCC.

          (c)  To the extent that a director or officer has been successful, on
     the merits or otherwise, in the defense of any proceeding to which he was a
     party, or in defense of any claim, issue, or matter therein, because he is
     or was a director or officer of the corporation, the corporation shall
     indemnify the director or officer against reasonable expenses incurred by
     him in connection therewith regardless of whether the director or officer
     has met the standards set forth in the GBCC and without any action or
     determination under Section 4 of this Article VII.

          (d)  Subject to the approval of the chief executive officer and the
     general counsel for the corporation, the officers of the corporation may
     indemnify an individual who is an employee of the corporation and who is
     made a party to a proceeding because he is or was an employee of the
     corporation against liability incurred in connection with a preceding to
     the fullest extent permitted under the GBCC, as the same now exists or may
     hereafter be amended (but only to the extent any such amendment permits the
     corporation to provide broader indemnification rights than the GBCC
     permitted the corporation to provide prior to such amendment).

     Section 3.   Advance for Expenses.
                  -------------------- 

          (a)  The corporation shall pay for or reimburse the reasonable
     expenses incurred by a director or officer who is a party to a proceeding
     in advance of final disposition of the proceeding if:

               (1)  The director or officer furnishes the corporation a written

                                       15
<PAGE>
 
          affirmation of his good faith belief that he has met the standard of
          conduct set forth in the GBCC; and

               (2)  The director or officer furnishes the corporation a written
          undertaking, executed personally or on his behalf, to repay any
          advances if it is ultimately determined that he is not entitled to
          indemnification under this Article

          (b)  The undertaking required by paragraph (2) of subsection (a) of
     this Section 3 must be an unlimited general obligation of the director or
     officer but need not be secured and may be accepted without reference to
     financial ability to make repayment.

     Section 4.  Limitations on Indemnification.
                 ------------------------------ 

          (a)  The corporation shall not indemnify a director under Section 2 of
     this Article VII unless a determination has been made in the specific case
     that indemnification of the director is permissible in the circumstances
     because he has met the standard of conduct set forth in the GBCC.

          (b)  The corporation shall indemnify an officer under Section 2 of
     this Article VII unless a determination has been made in the specific case
     that indemnification of the officer is precluded in the circumstances
     because he has failed to meet the standard of conduct set forth in the
     GBCC.

          (c)  In either paragraph (a) or (b) above, such determination shall be
     made within 60 days of the request for indemnification:

               (i)   By the Board of Directors by majority vote of a quorum
          consisting of directors not at the time parties to the proceeding;

               (ii)  If a quorum cannot be obtained under paragraph (i) of this
          subsection, by majority vote of a committee duly designated by the
          Board of Directors (in which designation directors who are parties may
          participate), consisting solely of two or more directors not at the
          time parties to the proceeding;

               (iii) By special legal counsel:

                    (A)  Selected by the Board of Directors or its committee in
               the manner prescribed in paragraph (i) or (ii) of this
               subsection; or

                    (B)  If a quorum of the Board of Directors cannot be
               obtained under paragraph (i) of this subsection and a committee
               cannot be designated under paragraph (ii) of this subsection,
               selected by majority vote of the full Board of Directors (in
               which selection directors who are parties may participate); or

                                       16
<PAGE>
 
               (iv)  By the shareholders, but the shares owned by or voted under
          the control of the officers and directors who are at the time parties
          to the proceeding may not be voted on the determination;

     provided, however, that following a change of control of the corporation,
     with respect to all matters thereafter arising out of acts, omissions or
     events prior to the change of control of the corporation concerning the
     rights of any person seeking indemnification under this Article VII, such
     determination shall be made by special legal counsel selected by such
     person and approved by the Board of Directors or its committee in the
     manner described in Section 4(c)(iii) above (which approval shall not be
     unreasonably withheld), which counsel has not otherwise performed services
     (other than in connection with similar matters) within the five years
     preceding its engagement to render such opinion for such person or for the
     corporation or any affiliates (as such term is defined in Rule 405 under
     the Securities Act of 1933, as amended) of the corporation (whether or not
     they were affiliates when services were so performed) ("Independent
     Counsel"). Unless such person has theretofore selected Independent Counsel
     pursuant to this Section 4 and such Independent Counsel has been approved
     by the corporation, legal counsel approved by a resolution or resolutions
     of the Board of Directors of the corporation prior to a change of control
     of the corporation shall be deemed to have been approved by the corporation
     as required. Such Independent Counsel shall determine as promptly as
     practicable whether and to what extent such person would be permitted to be
     indemnified under applicable law and shall render its written opinion to
     the corporation and such person to such effect. In making a determination
     under this Section 4, the special legal counsel and Independent Counsel
     referred to above shall determine that indemnification is permissible
     unless clearly precluded by this Article VII or the applicable provisions
     of the GBCC. The corporation agrees to pay the reasonable fees of the
     Independent Counsel referred to above and to fully indemnify such
     Independent Counsel against any and all expenses, claims, liabilities and
     damages arising out of or relating to this Article or its engagement
     pursuant hereto.

          (d)  Authorization of indemnification or an obligation to indemnify
     and evaluation as to reasonableness of expenses shall be made as set forth
     in paragraph (c) above.

          (e)  Indemnification under this Article VII in connection with a
     proceeding by or in the right of the corporation shall be limited to
     reasonable expenses incurred in connection with the proceeding.

     Section 5.   Enforceability. The provisions of this Article shall be
                  --------------                                         
applicable to all proceedings commenced after its adoption, whether such arise
out of events, acts, omissions or circumstances which occurred or existed prior
or subsequent to such adoption, and shall continue as to a person who has ceased
to be a director or officer and shall inure to the benefit of the heirs,
executors and administrators of such person. This Article shall be deemed to
grant each person who is entitled to indemnification hereunder rights against
the corporation to enforce the 

                                       17
<PAGE>
 
provisions of this Article, and any repeal or other modification of this Article
or any repeal or modification of the GBCC or any other applicable law shall not
limit any rights of indemnification then existing or arising out of events,
acts, omissions, circumstances occurring or existing prior to such repeal or
modification, including, without limitation, the right to indemnification for
proceedings commenced after such repeal or modification to enforce this Article
with regard to acts, omissions, events or circumstances occurring or existing
prior to such repeal or modification.

     Section 6.   Severability. If this Article or any portion hereof shall be
                  ------------                                                
invalidated on any ground by any court of competent jurisdiction, then the
corporation shall nevertheless indemnify each director or officer of the
corporation as to liabilities incurred in connection with any proceeding,
including an action by or in the right of the corporation, to the full extent
permitted by any applicable portion of this Article that shall not have been
invalidated and to the full extent permitted by applicable law.

     Section 7.   Statements to Shareholders. If the corporation indemnifies or
                  --------------------------                                   
advances expenses to an officer or director under this Article VII in connection
with a proceeding by or in the right of the corporation, the corporation shall
report the indemnification or advance in writing to the shareholders with or
before the notice of the next shareholders' meeting.

          (o)  "Purchase Price" shall mean the Exercise Price times the number

     4.   ADMINISTRATION.
          -------------- 

          (a)  Committee.  Unless otherwise determined by the Board from time
               ---------                                                     
     to time, Option grants under this Plan shall be made by the Committee.
     Acts of a majority of the Committee at a meeting at which a quorum is
     present, or acts reduced to or approved in writing by the unanimous
     consent of the members of the Committee, shall be the valid acts of the
     Committee.

          The Committee shall from time to time at its discretion select the
     Employees who are to be granted Options, determine the number of Shares
     to be optioned to each Optionee and set the terms of the Options.  No
     member of the Committee shall be liable for any action or determination
     made in good faith with respect to this Plan or any Option granted
     hereunder.

          (b)  Administrator.  The Committee shall appoint an officer of the
               -------------                                                
     Corporation as the Administrator of the Plan.  The Administrator shall
     have full authority to construe, interpret and administer the Plan, and,
     except as to matters which are expressly reserved herein for
     determination by the Board or the Committee, the Administrator's
     decisions and determinations in the administration of the Plan shall be
     final, conclusive and binding on all persons, including, without
     limitation, the Corporation, the shareholders and directors of the
     Corporation and any persons having any interests in any Options granted
     under this Plan.

     5.   PARTICIPATION.
          ------------- 

     The Optionees shall be those key Employees of the Corporation or the
Subsidiaries to whom Options may be granted from time to time by the Committee.

     6.   STOCK.
          ----- 

     The stock subject to Options granted under this Plan shall be Shares of
the Corporation's authorized but unissued or reacquired Common Stock.  The
aggregate number of Shares which may be issued upon exercise of Options under
this Plan shall not exceed Three Million (3,000,000).  The number of Shares
subject to Options outstanding at any time shall not exceed the number of Shares
remaining available for issuance under this Plan.  Whenever an Optionee's rights
to exercise an Option as to any Shares shall cease for any reason before he or
she has exercised such Option as to such Shares, the Option shall be deemed
terminated to that extent and such Shares shall again be available for issuance
under this Plan.  The limitations established by this Section 6 shall be subject
to adjustment in the manner provided in Section 9 hereof upon the occurrence of
an event specified in Section 9.

     7.   TERMS AND CONDITIONS OF OPTIONS.
          ------------------------------- 

          (a)  Stock Option Agreements.  Options shall be evidenced by written
               -----------------------                                        
     Option Agreements in such form as the Committee shall from time to time
     determine.  Such Option Agreements shall comply with and be subject to
     the terms and conditions set forth herein.

                                       3
<PAGE>
 
          (b)  Option Exercisable.  Except as otherwise provided in this Plan,
               ------------------                                             
     Options held by an Optionee may be exercised only while the Optionee is
     employed by the Corporation or a Subsidiary.

          (c)  Number of Shares.  Each Option shall state the number of Shares
               ----------------                                               
     to which it pertains.

          (d)  Exercise Price.  Each Option shall state the Exercise Price,
               --------------                                              
     which shall not be less than the Fair Market Value on the date of grant.
     The Exercise Price shall be subject to adjustment as provided in Section
     9 hereof.

          (e)  Medium and Time of Payment.  Upon the exercise of any Option,
               --------------------------                                   
     the Purchase Price shall be paid in full in United States dollars by
     certified check or other form of payment acceptable to the Administrator;
     provided, however, that if the applicable Option Agreement so provides,
     or the Committee, in its sole discretion otherwise approves thereof, the
     Purchase Price may be paid, (i) by the surrender of Shares, in good form
     for transfer, owned by the person exercising the Option and having a Fair
     Market Value on the date of exercise equal to the Purchase Price, or (ii)
     in any combination of cash and Shares, as long as the sum of the cash so
     paid and the Fair Market Value of the Shares so surrendered equals the
     Purchase Price.

          In the event the Corporation determines that it is required to
     withhold state or Federal income tax as a result of the exercise of an
     Option, as a condition to the exercise thereof an Optionee must make
     arrangements satisfactory to the Administrator to enable it to satisfy
     such withholding requirements.  Payment of such withholding requirements
     may be made, at the election of the Optionee, (i) in cash, (ii) by
     delivery of Shares registered in the name of Optionee, which Shares have
     a Fair Market Value at the time of exercise equal to the amount to be
     withheld, (iii) by the Corporation withholding Shares subject to the
     Option, which Shares have a Fair Market Value at the time of exercise
     equal to the amount to be withheld, or (iv) any combination of (i), (ii)
     and (iii) above.

          (f)  Term and Time for Exercise.  Each Option shall state the time or
               --------------------------                                      
     times when all or part thereof becomes exercisable.  No Option shall be
     exercisable more than ten (10) years (or less, in the discretion of the
     Committee) from the date it was granted.  If the Committee does not
     determine otherwise, any Option granted under this Plan:

               (1)  Shall be exercisable as to not more than 25% of the total
          number of Shares covered by the Option immediately upon, and during
          the year following, the date of the grant;

               (2)  Shall be exercisable as to not more than 50% of the total
          number of Shares covered by the Option on, and during the year
          following, the first anniversary of the date of grant;

                                       4
<PAGE>
 
               (3)  Shall be exercisable as to not more than 75% of the total
          number of Shares covered by the Option on, and during the year
          following, the second anniversary of the date of grant; and

               (4)  Shall be fully exercisable on the third anniversary of the
          date of grant and thereafter prior to expiration of the Option.

          If the Committee does not determine otherwise with respect to any
     Option granted hereunder, in the event that the employment of the
     Optionee by the Corporation or any Subsidiary of the Corporation
     terminates for any reason whatsoever, other than death or Retirement,
     prior to the Option(s) held by that person becoming fully exercisable as
     provided above, such Option(s) shall automatically expire with respect to
     the unexercisable portion on the date of termination of employment
     without any further action or documentation.

          (g)  Non-transferability of Options.  During the lifetime of the
               ------------------------------                             
     Optionee, the Option shall be exercisable only by the Optionee and shall
     not be assignable or transferable. In the event of the Optionee's death,
     the Option shall not be transferable by the Optionee other than by will
     or the laws of descent and distribution.  Any other attempted alienation,
     assignment, pledge, hypothecation, attachment, execution or similar
     process, whether voluntary or involuntary, with respect to all or any
     part of any Option or right hereunder, shall be null and void and, at the
     Corporation's option, shall cause all of the Optionee's rights under the
     Option to terminate.

          (h)  Change in Control of the Corporation.
               ------------------------------------ 

               (1)  Contrary Provisions.  Notwithstanding anything contained
                    -------------------                                     
          in this Plan to the contrary, in the event of a Change in Control,
          the provisions of this Subsection 7(h) shall govern and supersede
          any inconsistent terms or provisions of this Plan.

               (2)  Change in Control.  For purposes of this Plan, a "Change
                    -----------------                                       
          in Control" shall mean any of the following events:

                    (a)  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 Corporation's then outstanding voting securities (the
               "Voting Securities"), provided, however, that for purposes of
                                     --------  -------                      
               this Subsection 7(h)(2)(a), the Voting Securities acquired
               directly from the Corporation 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

                                       5
<PAGE>
 
                    (b)  The individuals who are members of the Incumbent
               Board (as hereinafter defined), cease for any reason to
               constitute at least two-thirds of the Board for purposes of
               this Subsection 7(h)(2)(b).  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 Corporation'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

                    (c)  Approval by stockholders of the Corporation of (i) a
               merger or consolidation involving the Corporation if the
               stockholders of the Corporation 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 Corporation or an agreement for the sale or other
               disposition of all or substantially all of the assets of the
               Corporation.

                    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 Corporation
               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 Corporation in the same
               proportion as their ownership of stock in the Corporation
               immediately prior to such acquisition.

                    Moreover, notwithstanding the foregoing, a Change in
               Control shall not be deemed to occur solely because any 

                                       6
<PAGE>
 
               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 Corporation 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 Corporation, and after such share acquisition by the
               Corporation, 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.

                    Notwithstanding anything contained in this Plan to the
               contrary, if a Change in Control takes place and an Optionee's
               employment is terminated prior to the completed Change in Control
               and the Optionee 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
               Optionee shall mean the date immediately prior to the date of
               termination of such Optionee's employment.

               (3)  Time for Exercise Upon a Change in Control.  Upon a Change
                    ------------------------------------------                
          in Control, all options granted under this Plan that are held by
          Employees at the time of such Change in Control shall become
          immediately exercisable in full, without regard to the years that have
          elapsed from the date of grant.

               (4)  Termination of Employment Following Change in Control.  If
                    -----------------------------------------------------     
          an Optionee's employment terminates following a Change in Control
          other than for "cause" (as hereinafter defined), the applicable
          provisions of Subsection 7(i) of this Plan shall apply except that as
          of and after the date of the Change in Control, the Administrator
          shall not make any determination or take any action in connection with
          an Optionee's termination of employment which would cause any option
          granted under this Plan (i) to not be exercisable in full or (ii) to
          expire earlier than the latest date allowable under Subsection 7(i) as
          applicable.

               (5)  Amendment or Termination.
                    ------------------------ 

                    (a)  Subsection 7(h) of this Plan shall not be amended or
               terminated at any time.

<PAGE>
 
                    (b)  Any amendment or termination of this Plan prior to a
               Change in Control which (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,
               shall be null and void and shall have no effect whatsoever.

          (i)  Cessation of Employment; etc.  After an Optionee ceases to be an
               ----------------------------                                    
     Employee, his or her rights to exercise any unexercised Option then held by
     the Optionee shall be determined as provided in this Subsection 7(i). No
     Option may be exercised after its term expires or the Option is otherwise
     canceled.

               (1)  Retirement.  If an Optionee ceases to be an Employee
                    ----------                                          
          because of Retirement (and not on account of termination for "cause"
          (as hereinafter defined)), such Optionee may exercise the Option
          immediately with respect to (i) the Shares which he or she could have
          purchased at the time of Retirement, and (ii) any Shares which would
          have become available for purchase under the Option if the Optionee's
          employment had continued for one year after the date of Retirement. To
          the extent unexercised, the Option shall expire two (2) years after
          the date of Retirement or the date of expiration of the Option as
          shown in the applicable Option Agreement, whichever shall occur first.

               (2)  Death.  If the Committee does not determine otherwise with
                    -----                                                     
          respect to any Option, upon the death of an Employee who at the time
          of his or her death holds an Option, the Option shall be exercisable
          immediately (by the executor or the administrator of the deceased
          Optionee's estate or by a person who acquired the right to exercise
          the option by bequest or inheritance or by reason of such death) with
          respect to (i) the Shares which could have been purchased by the
          deceased Optionee at the time of his or her death, and (ii) any Shares
          which would have become available for purchase under the Option if the
          Optionee's employment had continued for one year after the date of
          death. To the extent unexercised, the Option shall expire (i) one year
          after the date of such death, or (ii) in the event of death following
          termination of employment by reason of Retirement as described in
          Subsection 7(i)(1) immediately above, the expiration date of the
          Option after Retirement, whichever occurs last. Notwithstanding the
          foregoing, the Committee may, in a special case, permit a longer
          period for exercise of an Option after death of an Optionee, but in no
          event shall such period extend beyond the date of expiration of the
          Option as set forth in the Option Agreement.

               (3)  Disability.  If an Optionee ceases active service as an
                    ----------                                             
          Employee by reason of Disability, such Optionee shall have the right
          to exercise the Option at any time within twelve (12) months after
          such cessation of employment, but except as provided in the applicable
          Option Agreement, only to the extent that, at the date of such
          cessation of employment, the Optionee's right to exercise such Option

                                       8
<PAGE>
 
          had accrued pursuant to the terms of the applicable Option Agreement
          and had not previously been exercised.

               (4)  Termination for Cause.  If an Optionee's employment is
                    ---------------------                                 
          terminated for "cause" (as hereinafter defined), such Optionee's
          Option(s) shall expire immediately upon the giving to such Optionee of
          the notice of such termination. "Cause," for purposes of this
          Subsection 7(i), shall mean dishonest or fraudulent conduct which
          would normally be considered as sufficient basis for discharging an
          employee from a management and/or a supervisory position, or
          negligence, inaction or misconduct which constitutes failure by the
          Optionee to meet such Optionee's obligations and perform such
          Optionee's duties of employment.

               (5)  Other Reasons.  If an Optionee  ceases to be an Employee
                    -------------                                           
          for any reason other than those mentioned above in Subsections (1),
          (2), (3) or (4), the Optionee shall have the right to exercise the
          Option at any time within thirty (30) days following such cessation,
          discharge or termination, but, except as otherwise provided in the
          applicable Option Agreement, only to the extent that, at the date of
          cessation, discharge or termination, the Optionee's right to exercise
          such Option had accrued pursuant to the terms of the applicable Option
          Agreement and had not previously been exercised.

               (6)  Leave of Absence.  An Optionee's employment with the
                    ----------------                                    
          Corporation shall not be considered as having been terminated while
          the Optionee is on military or sick leave or other bona fide leave of
          absence (such as temporary employment by the Government) if the period
          of such leave does not exceed ninety (90) days, or, if longer, so long
          as the Optionee's right to re-employment with the Corporation is
          guaranteed either by statute or by contract. Where the period of such
          leave exceeds ninety (90) days and where the Optionee's rights to re-
          employment is not guaranteed either by statute or by contract, the
          Optionee's employment will be deemed to have terminated on the ninety-
          first (91st) day of such leave.

          (j)  Rights as a Stockholder.  No one shall have rights as a
               -----------------------                                
     stockholder with respect to any Shares covered by his or her Option until
     the date of the issuance of a stock certificate for such Shares. No
     adjustment shall be made for dividends (ordinary or extraordinary, whether
     in cash, securities or other property), distributions or other rights for
     which the record date is prior to the date such stock certificate is
     issued, except as provided in Section 9 hereof.

          (k)  Modification, Extension and Renewal of Options.  Within the
               ----------------------------------------------             
     limitations of this Plan, the Committee may modify, extend or renew
     outstanding Options or accept the cancellation of outstanding Options (to
     the extent not previously exercised) for the granting of new Options in
     substitution therefor. The foregoing notwithstanding, no modification of an
     Option shall, without the consent of the Optionee, alter or impair any
     rights or obligations under any Option previously granted.

                                       9
<PAGE>
 
          (l)  Other Provisions.  The Option Agreements authorized under this
               ----------------                                              
     Plan may contain such other provisions not inconsistent with the terms of
     this Plan as the Committee shall deem advisable (including, without
     limitation, restrictions upon the exercise of the Option or subjecting the
     Shares issued pursuant to the exercise of an Option to rights of repurchase
     by the Corporation).

          (m)  Substitution of Option.  Notwithstanding any inconsistent
               ----------------------                                   
     provisions or limits under this Plan, in the event the Corporation acquires
     (whether by purchase, merger or otherwise) all or substantially all of the
     outstanding capital stock or assets of another corporation by any
     reorganization or other transaction qualifying under Section 425 of the
     Code, the Committee may, in accordance with the provisions of that Section,
     substitute options under this Plan for options under the plan of the
     acquired company provided (i) the excess of the aggregate Fair Market Value
     of the Shares subject to an Option immediately after the substitution over
     the aggregate Option Price of such Shares is not more than the similar
     excess immediately before such substitution and (ii) the new Option does
     not give persons additional benefits, including any extension of the
     exercise period.

     8.   TERM OF PLAN.
          ------------ 

     Options may be granted pursuant to this Plan until the expiration of this
Plan on November 13, 2001.

     9.   RECAPITALIZATIONS.
          ----------------- 

     The number of Shares covered by this Plan as provided in Section 6 hereof,
the number of Shares covered by each outstanding Option and the Exercise Price
thereof shall be proportionately adjusted for any increase or decrease in the
number of issued Shares resulting from a subdivision or consolidation of Shares
or the payment of a stock dividend (but only of Common Stock) or any other
increase or decrease in the number of issued Shares effected without receipt of
consideration by the Corporation.

     Unless provisions are made for the continuance of this Plan or the
assumption by, or the substitution for outstanding Options of new options
covering the stock of, a successor employer corporation, or a parent or
subsidiary thereof, with appropriate adjustments as to the number and kind of
shares and prices, in the event of any merger, consolidation, reorganization,
liquidation or dissolution of the Corporation, or any exchange of Shares, each
outstanding Option shall automatically be deemed to pertain to the securities
and other property to which a holder of the number of Shares covered by the
Option would have been entitled to receive in connection with any such event,
and shall no longer pertain to the Shares. A dissolution or liquidation of the
Corporation shall cause each outstanding Option to terminate.

     To the extent that the foregoing adjustments relate to securities of the
Corporation, such adjustments shall be made by the Committee, whose
determination shall be conclusive and binding on all persons.

                                       10
<PAGE>
 
     Except as expressly provided in this Section 9, the Optionee shall have
no rights by reason of any subdivision or consolidation of shares of stock of
any class, the payment of any stock dividend or any other increase or decrease
in the number of shares of stock of any class or by reason of any dissolution,
liquidation, merger or consolidation or spin-off of assets or stock of another
corporation, and any issue by the Corporation of shares of stock of any class,
or securities convertible into shares of stock of any class, shall not affect,
and no adjustment by reason thereof shall be made with respect to, the number or
Exercise Price of Shares subject to an Option.

     The grant of an Option pursuant to this Plan shall not affect in any way
the right or power of the Corporation to make adjustments, reclassifications,
reorganizations or changes of its capital or business structure, to merge or
consolidate or to dissolve, liquidate, sell or transfer all or any part of its
business or assets.

     10.  SECURITIES LAW REQUIREMENTS.
          --------------------------- 

          (a)  Securities Act Requirements.  No Option granted pursuant to this
               ---------------------------                                     
     Plan shall be exercisable in whole or in part, and the Corporation shall
     not be obligated to sell any Shares subject to any such Option, if such
     exercise and sale would, in the opinion of counsel for the Corporation,
     violate the Securities Act of 1933 (or other Federal or State statutes
     having similar requirements) as it may be in effect at that time.

          As a condition to the issuance of any Shares upon exercise of an
     Option under this Plan, the Administrator may require the Optionee to
     furnish a written representation that he is acquiring the shares for
     investment and not with a view to distribution to the public. Such
     representations shall be required in cases where, in the opinion of the
     Administrator, they are necessary to enable the Corporation to comply with
     the provisions of the Securities Act of 1933, and any shareholder who gives
     such representation shall be released from it at such a time as the shares
     to which it applies are registered pursuant to the Securities Act of 1933.

          (b)  Listing and Regulatory Requirements.  Each Option shall be
               -----------------------------------                       
     subject to the further requirements that if at any time the Committee shall
     determine in its discretion that the listing or qualification of the shares
     of stock subject to such Option under any securities exchange requirements
     or under any applicable law, or the consent or approval of any governmental
     regulatory body, is necessary or desirable as a condition of, or in
     connection with, the granting of such Option or the issue of Shares
     thereunder, such Option may not be exercised in whole or in part unless and
     until such listing, qualification, consent or approval shall have been
     effected or obtained free of any conditions not acceptable to the
     Committee.

     11.  AMENDMENT OF THIS PLAN.
          ---------------------- 

     The Board may from time to time, with respect to any Shares at the time
not subject to Options, suspend or discontinue this Plan or revise or amend it
in any respect whatsoever.

     12.  APPLICATION OF FUNDS.
          -------------------- 

     The proceeds received by the Corporation from the sale of Common Stock
pursuant to the exercise of an Option will be used for general corporate
purposes.

     13.  EXECUTION.
          --------- 

     To record the adoption of this Plan by the Board on November 13, 1996, and
its most recent amendment on November 11, 1998, the Corporation has caused this
Plan to be executed by its authorized officers.

ownership of common stock of the Company on reasonable terms, to provide
compensation opportunities for superior financial results and outstanding
personal performance, to foster in participants a strong incentive to put forth
maximum effort for the continued success and growth of the Company and its
Subsidiaries, and to assist in attracting and retaining the best available
individuals to the Company and its Subsidiaries.

meaning set forth below:

          2.1  "Affiliate" means, with respect to any specified person or

          (as the term person is used for purposes of Section 13(d) or 14(d) of
          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 paragraph (a), 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

<PAGE>
 
               (c)  Approval by stockholders of the Company of (i) a merger or

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.


          2.6  "Code" means the Internal Revenue Code of 1986, as amended from
time to time, and reference to any specific provisions of the Code shall refer
to the corresponding provisions of the Code as it may hereafter be amended or
replaced.

of the Board or any other committee appointed by the Board whose members meet
the requirements for eligibility to serve set forth in Section 4 of the Plan and
which is vested by the Board with responsibility for the administration of the
Plan; provided, however, that only those members of  the committee of the Board
who participate in decisions relative to Awards under this Plan shall be deemed

the date(s) in question, or, if the Shares shall not have been traded on any
such date(s), the closing sale price on the New York Stock Exchange Composite on
the first day prior thereto on which the Shares were so traded or if the Shares
are not traded on the New York Stock Exchange, such other amount as may be
determined by the Committee by any fair and reasonable means. Fair Market Value
determined by the Committee in good faith shall be final, binding and conclusive
on all parties.

          2.12 "Incumbent Board" means the individuals who as of August 20, 1990

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 Exchange Act) or other actual or threatened
solicitation of proxies or consents by or on behalf of a Person other than the

year of the Company during any part of which the Plan is effective shall be one
and one-half percent (1-1/2%) of the number of Shares of the Company outstanding
as of the first day of such fiscal year; and commencing in the Company's 1995
fiscal year and in each fiscal year thereafter, subtracting from such maximum
number of Shares the number of Shares subject to options, if any, granted
pursuant to the Company's 1992 Employee Stock Option Plan.  The maximum number
of Shares available for which Awards may be granted in any particular fiscal
year pursuant to the previous sentence may be increased by an amount of up to
one-half of one percent (.5%) of the number of Shares outstanding as of the
first day of such fiscal year, provided that the number of Shares which would
otherwise be available for Awards in the next fiscal year shall be decreased by
the increased number of Shares made available pursuant to this sentence.  Such
Shares may be in whole or in part, as the Board shall from time to time
determine, authorized but unissued Shares, or issued Shares which shall have
been reacquired by the Company.  Notwithstanding anything to the contrary
contained in this Section 3.1, in no event shall more than four million
(4,000,000) Shares be cumulatively available for Awards of Incentive Stock
Options under this Plan.  The number of SARs payable in cash and the number of
units payable in cash under the Plan shall be counted when computing the total
number of Shares available for Awards under the Plan.  Any unused portion of the
percentage limit for any year shall be carried forward and made available for
Awards in succeeding years.

          3.2  CERTAIN LIMITATIONS.  The maximum number of Shares with respect
to which Options and SARs payable in Shares which may be granted during any
fiscal year to any Employee shall not exceed 400,000.  The maximum dollar value
with respect to which Awards (other than Options and SARs payable in Shares)
that are intended to qualify as performance-based compensation under Code
Section 162(m)(4)(C) which may be paid to any Employee for any particular
Performance Period shall be Four Million Dollars ($4,000,000).

          3.3  SHARES UNDERLYING EXPIRED, CANCELLED OR UNEXERCISED AWARDS.  Any
Shares subject to issuance upon exercise of an Option or SAR, but which are not
issued because of a surrender, lapse, expiration or termination of any such
Option or SAR prior to issuance of the Shares, or any Shares subject to an SAR
paid in cash, shall once again be available for issuance in satisfaction of
Awards. Similarly, any Shares issued or issuable pursuant to a Restricted Stock
Award or Performance Award which are subsequently forfeited or not issued
pursuant to the terms of the grant shall once again be available for issuance in
satisfaction of Awards.

     4.   ADMINISTRATION OF THE PLAN.  The Board shall appoint the Committee,
which shall consist of not less than two (2) members of the Board, each of whom
is a "Non-Employee Director" as defined in Rule 16b-3.  Unless the Board
determines otherwise, the Committee shall be comprised solely of "outside"
directors within the meaning of Section 162(m)(4)(C)(i) of the Code.  Subject to
the provisions of the Plan, the Committee shall have full authority, in its
discretion, to 

                                       5
<PAGE>
 
determine the Employees to whom Awards shall be granted, the number of Shares,
units or SARs to be covered by each of the Awards, and the terms (including
restrictions) of any such Award; to amend or cancel Awards (subject to Section
21 of the Plan); to accelerate the vesting of Awards; to require the
cancellation or surrender of any options, stock appreciation rights, units or
restricted stock awards (to the extent the restrictions have not yet lapsed)
previously granted under this Plan or any other plans of the Company as a
condition to the granting of an Award; to interpret the Plan; and to prescribe,
amend, and rescind rules and regulations relating to it, and generally to
interpret and determine any and all matters whatsoever relating to the
administration of the Plan and the granting of Awards hereunder. The Board may,
from time to time, appoint members to the Committee in substitution for or in
addition to members previously appointed and may fill vacancies, however caused,
in the Committee. The Committee shall make such rules and regulations for the
conduct of its business as it shall deem advisable. All determinations and
decisions by the Committee in the exercise of its powers shall be final, binding
and conclusive. No member of the Committee shall be liable, in the absence of
bad faith, for any act or omission with respect to his service on the Committee.

     5.  EMPLOYEES TO WHOM AWARDS MAY BE GRANTED.  Awards may be granted in each
year or portion thereof while the Plan is in effect to such of the Employees as
the Committee, in its discretion, shall determine.  In determining the Employees
to whom Awards shall be granted, the amount of the Award, the number of Shares
to be granted or subject to purchase under such Awards and the number of SARs to
be granted, the Committee shall take into account the duties of the respective
Employees, their present and potential contributions to the success of the
Company and its Subsidiaries, and such other factors as the Committee shall deem
relevant in connection with accomplishing the purposes of the Plan. No Award
shall be granted to any member of the Committee so long as his or her membership
on the Committee continues or to any member of the Board who is not also an
Employee.

     6.   STOCK OPTIONS.

          6.1  TYPES OF OPTIONS.  Options granted under this Plan may be (i)
Incentive Stock Options, (ii) Non-Qualified Stock Options, or (iii) a
combination of the foregoing.  The Award Letter shall designate whether an
Option is an Incentive Stock Option or a Non-Qualified Stock Option.  Any Option
which is designated as a Non-Qualified Stock Option shall not be treated by the
Company or the Participant to whom the Option is granted as an Incentive Stock
Option for federal income tax purposes.

          6.2  OPTION PRICE.  The option price per Share of any Option granted
under the Plan shall not be less than the Fair Market Value of the Shares
covered by the Option on the date the Option is granted.  Notwithstanding
anything herein to the contrary, in the event an Incentive Stock Option is
granted to an Employee who, at the time such Incentive Stock Option is granted,
is a Ten-Percent Stockholder, then the option price per Share of such Incentive
Stock Option shall not be less than one hundred ten percent (110%) of the Fair
Market Value of the Shares covered by the Incentive Stock Option on the date the
Incentive Stock Option is granted.

          6.3  TERM OF OPTIONS.  Options granted hereunder shall be exercisable
for a Term of not more than ten (10) years from the date of grant and shall be
subject to earlier termination as hereinafter provided.  Each Award Letter
issued hereunder shall specify the Term of the Option, which Term shall be
determined by the Committee in accordance with its discretionary authority
hereunder.  Notwithstanding anything herein to the contrary, in the event an
Incentive Stock Option is granted to an Employee who, at the time such Incentive
Stock Option is granted, is a Ten-Percent Stockholder, then such Incentive Stock
Option shall not be exercisable more than five (5) years from the date of grant
and shall be subject to earlier termination as hereinafter provided.

                                       6
<PAGE>
 
     7.   LIMIT ON FAIR MARKET VALUE OF INCENTIVE STOCK OPTIONS. In any calendar
year, no Employee may be granted an Incentive Stock Option hereunder to the
extent that the aggregate fair market value (such fair market value being
determined as of the date of grant of the Option in question) of the Shares with
respect to which Incentive Stock Options first become exercisable by the
Employee during any calendar year (under all such plans of the Employee's
employer corporation, its Parent, if any, and its Subsidiaries, if any) exceeds
the sum of One Hundred Thousand Dollars ($ 100,000).  For purposes of the
preceding sentence, Options shall be taken into account in the order in which
they were granted.  Any Option granted under the Plan which is intended to be an
Incentive Stock Option, but which exceeds the limitation set forth in this
Section 7, shall be a Non-Qualified Stock Option to the extent that a portion of
the Option exceeds this limitation.

     8.   STOCK APPRECIATION RIGHTS.

          8.1  GRANT OF SAR.  The Committee, in its discretion, may grant an
Employee an SAR in tandem with an Option or may grant an Employee an SAR on a
stand alone basis.  The Committee, in its discretion, may grant an SAR in tandem
with an Option either at the time the Option is granted or at any time after the
Option is granted, so long as the grant of the SAR is made during the period in
which grants of SARs may be made under the Plan.  The Committee, in its
discretion, may grant an SAR in tandem with an Option, which is exercisable
either in lieu of, or in addition to, exercise of the related Option.

          8.2  LIMITATIONS ON EXERCISE.  Each SAR granted in tandem with an
Option shall be exercisable to the extent, and only to the extent, the related
Option is exercisable and shall be for such Term as the Committee may determine
(which Term, which is not to exceed ten (10) years, may expire prior to the Term
of the related Option).  Each SAR granted on a stand alone basis shall be
exercisable to the extent, and for such Term, as the Committee may determine.
The SARs shall be subject to such other terms and conditions as the Committee,
in its discretion, shall determine and which are not otherwise inconsistent with
the Plan.  The terms and conditions may include Committee approval of the
exercise of the SAR, limitations on the time within which and the extent to
which such SAR shall be exercisable, and limitations, if any, on the amount of
appreciation in value which may be recognized with regard to such SAR.  The
Company's obligation to any Participant exercising an SAR may be paid in cash or
Shares, or partly in cash or Shares, at the sole discretion of the Committee.
The Committee shall have at all times final control and authority over the form
of payment of any SAR.  If, and to the extent that, Shares are issued in
satisfaction of amounts payable on exercise of an SAR, the Shares shall be
valued at their Fair Market Value on the date of exercise.

          8.3  SARS IN TANDEM WITH INCENTIVE STOCK OPTIONS.  With respect to
SARs granted in tandem with Incentive Stock Options, the following shall apply:

               (a)  No SAR shall be exercisable unless the Fair Market Value of
          the Shares on the date of exercise exceeds the option price of the
          related Incentive Stock Option.

               (b)  In no event shall any amounts paid pursuant to the SAR
          exceed the difference between the Fair Market Value of the Shares on
          the date of exercise and the option price of the related Incentive
          Stock Option.

               (c)  The SAR must expire no later than the last date the related
          Incentive Stock Option can be exercised.

          8.4  SURRENDER OF OPTION OR SAR GRANTED IN TANDEM.  If the Award
Letter related to the grant of an SAR in tandem with an Option provides that the
SAR can only be 

                                       7
<PAGE>
 
exercised in lieu of the related Option, then, upon exercise of such SAR, the
related Option or portion thereof with respect to which such SAR is exercised
shall be deemed surrendered and shall not thereafter be exercisable and,
similarly, upon exercise of the Option, the related SAR or portion thereof with
respect to which such Option is exercised shall be deemed surrendered and shall
not thereafter be exercisable. If the Award Letter related to the grant of an
SAR in tandem with an Option provides that the SAR can be exercised in addition
to the related Option, then, upon exercise of such SAR, the related Option or
portion thereof with respect to which such SAR is exercised shall not be deemed
surrendered and shall continue to be exercisable and, similarly, upon exercise
of the Option, the related SAR or portion thereof with respect to which such
Option is exercised shall not be deemed surrendered and shall continue to be
exercisable.

     9.   EXERCISE OF RIGHTS UNDER OPTION OR SAR AWARDS.

          9.1  NOTICE OF EXERCISE.  An Employee entitled to exercise an Option
or SAR may do so by delivery of a written notice to that effect specifying the
number of Shares with respect to which the Option or SAR is being exercised and
any other information the Committee may prescribe.  Except as provided in
Section 9.2 below, the notice shall be accompanied by payment in full of the
purchase price of any Shares to be purchased, which payment may be made in cash
or, in Shares valued at Fair Market Value at the time of exercise or,  a
combination thereof.  No Shares shall be issued upon exercise of an Option until
full payment has been made therefor.  All notices or requests provided for
herein shall be delivered to the Company as determined by the Committee.

          9.2  CASHLESS EXERCISE PROCEDURES.  The Committee, in its sole
discretion, may establish procedures at the time of each grant of an Option or
SAR whereby an Employee, subject to the requirements of Rule 16b-3, Regulation
T, federal income tax laws, and other federal, state and local tax and
securities laws, can exercise an Option or a portion thereof without making a
direct payment of the option price to the Company.  If the Committee so elects
to establish a cashless exercise program, the Committee shall determine, in its
sole discretion, and from time to time, such administrative procedures and
policies as it deems appropriate and such procedures and policies shall be
binding on any Employee wishing to utilize the cashless exercise program.

     10.  RIGHTS OF OPTION AND SAR HOLDERS.  The holder of an Option or SAR
shall not have any of the rights of a stockholder with respect to the Shares
subject to purchase or issuance under such Award, except to the extent that one
or more certificates for such Shares shall be delivered to the holder upon due
exercise of the Option or SAR.

     11.  RESTRICTED STOCK AWARDS.  Restricted Stock Awards granted under the
Plan shall be subject to such terms and conditions as the Committee may, in its
discretion, determine.  Restricted Stock Awards issued under the Plan shall be
evidenced by an Award Letter in such form as the Committee may from time to time
determine.  Restricted Stock Awards may be subject to restrictions which lapse
over time with or without regard to Performance Objectives for a specific
Performance Period.  Unless the Committee decides otherwise in its sole and
absolute discretion based upon the circumstances existing at the time of the
grant of any Restricted Stock Award, Restricted Stock Awards which are subject
solely to time-based restrictions shall vest over a period of not less than
three years and Restricted Stock Awards which are subject to restrictions based
on Performance Objectives shall vest over a period of not less than one year.

          11.1  RECEIPT OF SHARES.  Each Award Letter shall set forth the number
of Shares issuable under the Restricted Stock Award evidenced thereby.  Subject
to the restrictions of Sections 11.2, 11.3 and 11.4 of the Plan and as set forth
in the related Award Letter, the number of Shares granted under a Restricted
Stock Award shall be issued to the recipient Employee thereof on the date of
grant of such Restricted Stock Award or as soon as may be practicable thereafter
and 

                                       8
<PAGE>
 
and deposited into escrow, if applicable.  If the Committee determines that a
Restricted Stock Award is intended to qualify as performance-based compensation
under Code Section 162(m)(4)(C), then such Restricted Stock Award shall be
subject to the attainment of Performance Objectives for a Performance Period.
Such specific Performance Objectives shall be established in writing no later
than ninety (90) days after the commencement of the Performance Period to which
the Performance Objectives relate, but in no event after twenty-five percent
(25%) of the Performance Period has elapsed.  In establishing the Performance
Objective or Performance Objectives, the Committee shall also establish a
schedule or schedules setting forth the portion of the Award which will be
earned or forfeited based on the degree of achievement of the Performance
Objectives actually achieved or exceeded as determined by the Committee.  The
Committee may at any time adjust the Performance Objectives and any schedules
and portions of payments related thereto, adjust the way Performance Objectives
are measured, or shorten any Performance Period if it determines that conditions
or the occurrence of events warrants such actions; provided, that this provision
shall not apply to any Restricted Stock Award 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 Award from so qualifying.  The Committee shall
have the right to reduce or eliminate the Restricted Stock Award payable upon
the attainment of a Performance Objective, but shall not have the discretion to
increase an Award upon the attainment of a Performance Objective with respect to
a Participant whose compensation for the particular year is subject to the
limits on tax deductibility in Code Section 162(m).

          11.2  RIGHTS OF RECIPIENT PARTICIPANTS.  Shares received pursuant to
Restricted Stock Awards shall be duly issued or transferred to the Participant,
and a certificate or certificates for such Shares shall be issued in the
Participant's name.  Subject to the restrictions in Section 11.3 of the Plan and
as set forth in the related Award Letter, the Participant shall thereupon be a
stockholder with respect to all the Shares represented by such certificate or
certificates and shall have all the rights of a stockholder with respect to such
Shares, including the right to vote such Shares and to receive dividends and
other distributions paid with respect to such Shares.  As a condition to issuing
Shares, the Committee may require a Participant to execute an escrow agreement
and any other documents which the Committee may determine.  In aid of such
restrictions, certificates for Shares awarded hereunder, together with a
suitably executed stock power signed by each recipient Participant, shall be
held by the Company in its control for the account of such Participant (i) until
the restrictions determined by the Committee, in its discretion, and as set
forth in the related Award Letter, lapse pursuant to the Plan or the Letter
Agreement, at which time a certificate for the appropriate number of Shares
(free of all restrictions imposed by the Plan or the Award Letter except those
established by the Committee at the time of grant of the Award) shall be
delivered to the Participant, or (ii) until such Shares are forfeited to the
Company and cancelled as provided by the Plan or the Award Letter.

          11.3  NON-TRANSFERABILITY OF RESTRICTED STOCK AWARDS.  Until such time
as the restrictions determined by the Committee or otherwise set forth in the
related Award Letter have lapsed, the Shares awarded to a Participant and held
by the Company pursuant to Section 11.2 of the Plan, and the right to vote such
Shares or receive dividends on such Shares, may not be sold, exchanged,
transferred, pledged, hypothecated or otherwise disposed of; provided, however,
that, if so provided in the Award Letter, such Shares may be transferred upon
the death of the Participant to such of his legal representatives, heirs and
legatees as may be entitled thereto by will or the laws of intestacy.

          11.4  RESTRICTIONS.  Shares received pursuant to Restricted Stock
Awards shall be subject to the terms and conditions as the Committee may
determine, including, without limitation, restrictions on the sale, assignment,
transfer or other disposition of such Shares and the requirement that the
Participant forfeit such Shares back to the Company upon termination of
employment for any reason or for specified reasons.

                                       9

     12.  PERFORMANCE AWARDS.

          12.1  PERFORMANCE PERIODS.  The Committee shall establish Performance
Periods applicable to Performance Awards.  There shall be no limitation on the
number of Performance Periods established by the Committee and more than one
Performance Period may encompass the same fiscal year.

          12.2  PERFORMANCE OBJECTIVES.  If the Committee determines that a
Performance Award is intended to qualify as performance-based compensation under
Code Section 162(m)(4)(C), then such Performance Award shall be subject to the
attainment of Performance Objectives for a Performance Period.  Such specific
Performance Objectives shall be established in writing no later than ninety (90)
days after the commencement of the Performance Period to which the Performance
Objectives relate, but in no event after twenty-five percent (25%) of the
Performance Period has elapsed.  In establishing the Performance Objective or
Performance Objectives, the Committee shall also establish a schedule or
schedules setting forth the portion of the Performance Award which will be
earned or forfeited based on the degree of achievement of the Performance
Objectives actually achieved or exceeded as determined by the Committee.  The
Committee may at any time adjust the Performance Objectives and any schedules
and portions of payments related thereto, adjust the way Performance Objectives
are measured, or shorten any Performance Period if it determines that conditions
or the occurrence of events warrant such actions; provided, that this provision
shall not apply to any Performance Award 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 Award from so qualifying.  The Committee shall
have the right to reduce or eliminate the compensation or Award payable upon the
attainment of a Performance Objective but shall not have the discretion to
increase an Award upon the attainment of a Performance Objective with respect to
a Participant whose compensation for the particular year is subject to the
limits on tax deductibility in Code Section 162(m).

          12.3  GRANTS OF PERFORMANCE AWARDS.  Performance Awards may be granted
under the Plan in such form and to such Employees as the Committee may from time
to time approve.  Performance Awards may be granted alone, in addition to or in
tandem with other Awards under the Plan.  Subject to the terms of the Plan, the
Committee shall determine the amount or number of Performance Awards to be
granted to a Participant and the Committee may impose different terms and
conditions on any particular Performance Award granted to any Participant. Each
grant of a Performance Award shall be evidenced by a written instrument stating
the number of Performance Shares or Performance Units granted, the Performance
Period, the Performance Objective or Performance Objectives, the proportion of
payments for performance between the minimum and full performance levels, if
any, restrictions applicable to Shares receivable in settlement, if any, and any
other terms, conditions, restrictions and rights with respect to such grant as
determined by the Committee.  The Committee may determine that the Participant
forfeit such Performance Awards back to the Company upon termination of
employment for any reason or for specified reasons.  The Committee may provide,
in its sole discretion, that during a Performance Period, a Participant shall be
paid cash amounts, with respect to each Performance Share or Performance Unit
held by such individual in the same manner, at the same time, and in the same
amount paid, as a dividend on any Share.

          12.4  NON-TRANSFERABILITY OF PERFORMANCE AWARDS.  Until such time as
the Performance Objectives as determined by the Committee have been met and
until any restrictions upon the Shares issued pursuant to any Performance Awards
have lapsed, Performance Awards and any rights related thereto may not be sold,
exchanged, transferred, pledged, hypothecated or otherwise disposed of by any
Participant.

                                       10
<PAGE>
 
          12.5  PAYMENT OF AWARDS.  As soon as practicable after the end of the
applicable Performance Period as determined by the Committee, the Committee
shall determine the extent to which the Performance Objectives have been met and
the extent to which Performance Awards are payable.  Payment and settlement of a
Performance Award shall be as follows:

                (a) In the case of Performance Shares, one or more stock
          certificates representing the number of Shares payable shall be
          delivered to the Participant, free of all restrictions except those
          established by the Committee at the time of the grant of the
          Performance Shares; and

                (b) In the case of Performance Units, entirely in cash, entirely
          in Shares, or in such combination of Shares and cash as the Committee
          may determine, in its discretion, at any time prior to such payment.
          If payment is to be made in the form of cash, the amount payable for
          each Performance Unit earned shall be equal to the dollar value of
          each Performance Unit (as determined by the Committee) times the
          number of earned Performance Units.

     13.  AWARD TERMS AND CONDITIONS.  Each Award Letter setting forth an Award
shall contain such other terms and conditions not inconsistent herewith as shall
be approved by the Board or by the Committee.  The Committee shall from time to
time adopt policies and procedures applicable to Awards that will govern the
lapse or non-lapse of restrictions and the rights of Participants and
beneficiaries in the event of death, disability, termination of employment, or
retirement of Participants or upon the occurrence of any other event determined
by the Committee, in its sole discretion, to be appropriate.  The Committee
shall have authority to define disability and retirement and other terms, and
the Committee's policies and procedures may differ with respect to Awards
granted at different times.  A Participant's rights in the event of death,
disability, termination of employment, or retirement or such other events shall
be set forth in the Award Letter that evidences an Award to the Participant.

     14.  NONTRANSFERABILITY OF AWARDS.  No Award under the Plan and no rights
and interests therein, including the right to any amounts or Shares payable, may
be assigned, pledged, hypothecated or otherwise transferred by a Participant
except to the extent so permitted under the terms of the Award Letter.  During
the lifetime of a Participant, Options and SARs are exercisable only by, and
payments in settlement of Awards will be payable only to, the Participant or his
or her legal representative.

     15.  VESTING OF AWARDS.  The Committee may, in its sole discretion, grant
Awards which vest over time and/or are based upon satisfaction of Performance
Objectives.  The Committee may, in its discretion, modify or change any
Performance Objectives concerning any Award or accelerate the vesting of any
Award; provided that the Committee shall not modify or change any Performance
Objective or accelerate the vesting of any Award that is intended to qualify as
performance-based compensation under Code Section 162(m)(4)(C) if and to the
extent that such modification, change or acceleration would prevent the Award
from so qualifying.

     16.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.  In the event of changes
in all of the outstanding Shares by reason of stock dividends, stock splits,
recapitalizations, mergers, consolidations, combinations, or exchanges of
shares, separations, reorganizations or liquidations or similar events or in the
event of extraordinary cash or non-cash dividends being declared with respect to
outstanding Shares or other similar transactions, the number and class of Shares
available under the Plan in the aggregate, the number and class of Shares
subject to Awards theretofore granted, the number of SARs therefore granted,
applicable purchase prices, applicable Performance Objectives for the
Performance Periods not yet completed and performance levels and portion of
payments related thereto, and all other applicable provisions, shall, subject to
the provisions of the 

                                       11
<PAGE>
 
Plan, be equitably adjusted by the Committee. The foregoing adjustment and the
manner of application of the foregoing provisions shall be determined by the
Committee in its sole discretion. Any such adjustment may provide for the
elimination of any fractional Share which might otherwise become subject to an
Award.

     17.  CHANGE IN CONTROL.

          17.1  EFFECT ON AWARDS.  In the event of a Change in Control, then (i)
all Options, SARs and Options in tandem with SARs then outstanding shall become
fully exercisable as of the date of the Change in Control, whether or not then
exercisable, (ii) all restrictions and conditions of all Restricted Stock Awards
then outstanding shall be deemed satisfied as of the date of the Change in
Control, and (iii) all Performance Shares and Performance Units shall be deemed
to have been fully earned as of the date of the Change in Control. Moreover, the
Committee, in its sole discretion, may at any time, and subject to the terms and
conditions as it may impose:  (a) grant Awards that become exercisable only in
the event of a Change in Control, (b) provide for Awards to be exercised
automatically and only for cash in the event of a Change in Control, and (c)
provide in advance or at the time of a Change in Control for cash to be paid in
settlement of any Award in the event of a Change in Control.

          17.2  TERMINATION OF EMPLOYMENT.  Notwithstanding anything contained
in this Plan to the contrary, in the event a Change in Control takes place and a
Participant's employment is terminated prior to the 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 the 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 the Change in Control in respect of such Participant shall mean the date
immediately prior to the date of termination of such Participant's employment.

     18.  FORM OF AWARDS.  Nothing contained in the Plan nor any resolution
adopted or to be adopted by the Board or the stockholders of the Company shall
constitute the granting of any Award.  An Award shall be granted hereunder at
such date or dates as the Committee may determine, subject to the Plan. Whenever
the Committee determines to grant an Award, the Secretary or the President of
the Company, or such other person as the Committee appoints, shall send notice
thereof to the Employee, in such form as the Committee approves, stating the
number of Shares, units and SARs subject to the Award, its Term, and the other
provisions, restrictions and conditions thereof.  The notice shall be
accompanied by a written Award Letter (and, in the case of a Restricted Stock
Award, by a blank stock power and/or escrow agreement for execution by the
Employee) which shall have been duly executed by or on behalf of the Company.
If the surrender of previously issued Awards is made a condition of the grant,
the notice shall set forth the pertinent details of such condition.  Execution
of an Award Letter by the recipient in accordance with the provisions of the
Plan shall be a condition precedent to the exercise or settlement of any Award.

     19.  WITHHOLDING FOR TAXES.

          19.1  COMPANY'S RIGHT TO PAYMENT FOR TAXES REQUIRED TO BE WITHHELD.
The Company shall, before any payment is made or a certificate for any Shares is
delivered or any Shares are credited to any brokerage account, deduct or
withhold from any payment under the Plan any Federal, state, local or other
taxes, including transfer taxes, required by law to be withheld or to require
the Participant or his beneficiary or estate, as the case may be, to pay any
amount, or the balance of any amount, required to be withheld.  The Company may
elect to deduct such taxes from any amounts payable then or any time thereafter
in cash to the Employee and, in the Employee's sole discretion, the payment of
such taxes may be made from Shares previously held by 

                                       12
<PAGE>
 
such Employee. If the Employee disposes of Shares acquired pursuant to an
Incentive Stock Option in any transaction considered to be a disqualifying
transaction under Sections 421 and 422 of the Code, the Employee must give the
Company written notice of such transfer and the Company shall have the right to
deduct any taxes required by law to be withheld from any amounts otherwise
payable to the Employee.

          19.2  EMPLOYEE ELECTION TO WITHHOLD SHARES. An Employee, in his sole
discretion, may elect to satisfy his or her tax liability with respect to the
exercise, vesting or settlement of an Award, by having the Company withhold
Shares otherwise issuable upon the exercise, vesting or settlement of the Award.

     20.  TERMINATION OF PLAN.  The Plan shall terminate ten (10) years from the
date hereof, and an Award shall not be granted under the Plan after that date
although the terms of any Awards may be amended at any date prior to the end of
its Term in accordance with the Plan.  Any Awards outstanding at the time of
termination of the Plan shall continue in full force and effect according to the
terms and conditions of the Award and this Plan.

     21.  AMENDMENT OF THE PLAN.  The Plan may be amended at any time and from
time to time by the Board, but no amendment without the approval of the
stockholders of the Company shall be made if stockholder approval under Section
422 of the Code or Rule 16b-3 would be required.  Notwithstanding the previous
sentence, no amendment to the Plan shall be made without the approval of the
stockholders of the Company 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, unless the Board determines that such approval is not
necessary to avoid loss of a deduction under Section 162(m) of the Code, such
approval will not avoid such a loss of deduction or such approval is not
advisable. Notwithstanding the discretionary authority granted to the Committee
in Section 4 of the Plan, no amendment of the Plan or any Award granted under
the Plan shall impair any of the rights of any Participant, without his or her
consent, under any Award theretofore granted under the Plan.

     22.  GOVERNING LAW; REGULATIONS AND APPROVALS.

          22.1  GOVERNING LAW.  This Plan and the rights of all persons
claiming hereunder shall be construed and determined in accordance of the laws
of the State of Georgia without giving effect to the conflicts of laws
principles thereof, except to the extent that such laws are preempted by federal
law.

          22.2  DELIVERY OF SHARES.  The obligation of the Company to issue,
sell and deliver Shares with respect to any Awards granted under this Plan shall
be subject to all applicable laws, rules and regulations, including all
applicable federal and state securities laws, and the obtaining of all such
approvals by governmental agencies as may be deemed necessary or appropriate by
the Committee.

          22.3  SECURITIES ACT REQUIREMENTS.  No award shall be granted and no
certificates for Shares pursuant to the grant or exercise of an Award shall be
delivered pursuant to this Plan if the grant or delivery would, in the opinion
of counsel for the Company, violate the Securities Act or any other Federal or
state statutes having similar requirements as may be in effect at that time. As
a condition of the issuance of any Shares pursuant to the grant or exercise of
an Award under this Plan, the Committee may require the recipient to furnish a
written representation that he or she is acquiring the Shares for investment and
not with a view to distribution to the public.  In the event that the
disposition of Shares acquired pursuant to the Plan is not covered by a then
current registration statement under the Securities Act, as amended, and is not
otherwise exempt

                                       13
<PAGE>
 
from such registration, such Shares shall be restricted against transfer to the
extent required by the Securities Act and Rule 144 of the Securities Act or the
regulations hereunder.

          22.4  LISTING AND REGULATORY REQUIREMENTS.  Each Award is subject to
the further requirements that, if at any time the Committee shall determine, in
its discretion, that the listing, registration or qualification of the Shares
subject to the Award is required by any securities exchange or under any
applicable law or the rule of any regulatory body, or is necessary or desirable
as a condition of, or in connection with, the granting of such Award or the
issuance of Shares thereunder, such Award will not be granted or exercised and
the Shares may not be issued unless and until such listing, qualification,
consent or approval shall have been effected or obtained free of any conditions
not acceptable to the Committee.

          22.5  SECTION 16.  With respect to persons subject to Section 16 of
the Exchange Act, transactions under this Plan are intended to comply with all
applicable conditions of Rule 16b-3 or its successors under the Exchange Act. To
the extent any provision under the Plan or action by the Committee fails to so
comply, it shall be deemed null and void to the extent permitted by law and
deemed advisable by the Committee.

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

     23.  DEFERRAL ELECTIONS.  The Committee may, pursuant to the terms of an
Award Letter,  permit any Participant receiving an Award to elect to defer his
or her receipt of a payment of cash or the delivery of Shares that would be
otherwise due such individual by virtue of the exercise, settlement, vesting or
lapse of restrictions regarding any Award made under the Plan.  If any such
election is permitted, the Committee shall establish rules and procedures for
such payment deferrals and include such rules and procedures in the Award
Letter, including the possible payment or crediting of reasonable interest on
such deferred amounts credited in cash and the payment or crediting of dividend
equivalents in respect of deferrals credited in Shares.

     24.  MISCELLANEOUS.

          24.1  EMPLOYMENT RIGHTS.  Neither the Plan nor any action taken
hereunder shall be construed as giving any Employee the right to participate
under the Plan, and a grant of an Award under the Plan shall not be construed as
giving any recipient of the grant any right to be retained in the employ of the
Company.

          24.2  NO TRUST OR FUND CREATED.  Neither the Plan nor any grant made
hereunder shall create or be construed to create a trust or separate fund of any
kind or a fiduciary relationship between the Company and any recipient of a
grant of an Award or any other person.  To the extent that any person acquires a
right to receive payments from the Company pursuant to a grant under the Plan,
such right shall be no greater than the right of any unsecured general creditor
of the Company.  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.

          24.3  FEES AND COSTS.  The Company shall pay all original issue taxes
on the exercise of any Award granted under the Plan and all other fees and
expenses necessarily incurred by the Company in connection therewith.

          24.4  AWARDS TO FOREIGN NATIONALS.  Without amending the Plan, Awards
may be granted to participants who are foreign nationals or who are employed
outside the United 

                                       14
<PAGE>
 
States or both, on such terms and conditions different than those specified in
the Plan as may, in the judgment of the Committee, be necessary or desirable to
further the purpose of the Plan.

          24.5  OTHER PROVISIONS.  As used in the Plan, and in Awards and other
documents prepared in implementation of the Plan, references to the masculine
pronoun shall be deemed to refer to the feminine or neuter, and references in
the singular or the plural shall refer to the plural or the singular, as the
identity of the person or persons or entity or entities being referred to may
require.  The captions used in the Plan and in such Awards and other documents
prepared in implementation of the Plan are for convenience only and shall not
affect the meaning of any provision hereof or thereof.

     25.  EFFECTIVENESS OF THE PLAN.  The Plan shall become effective when
approved by the Board.  The Plan shall thereafter be submitted to the Company's
stockholders for approval and unless the Plan is approved by the affirmative
votes of the holders of shares having a majority of the voting power of all
shares represented at a meeting duly held in accordance with Georgia law within
twelve (12) months after being approved by the Board, the Plan and all Awards
made under it shall be void and of no force and effect.

     To record the adoption of the Plan (as amended and restated) by the Board
on November 11, 1998, the Company has caused its authorized officers to affix
the corporate name and seal hereto.

                                    FORM OF
                              FIRST AMENDMENT TO
                        SEVERANCE PROTECTION AGREEMENT
                                BY AND BETWEEN
                           SCIENTIFIC-ATLANTA, INC.
                                      AND
                              (NAME_OF_EXECUTIVE)

This First Amendment (this "Amendment") is entered into this ____ day of
January, 1999, by and between Scientific-Atlanta, Inc. ("S-A") and
(Name_of_Executive) ("Executive").

WHEREAS, S-A and Executive entered into that certain Severance Protection
Agreement, dated (Date) (the "Agreement"); and

WHEREAS, S-A and Executive desire to amend the Agreement;

NOW, THEREFORE, in consideration of the foregoing and the agreements set forth
below, the parties agree as follows:

1.   Section 2.3 of the Agreement is hereby amended to read in its entirety as
     follows:

          2.3  Disability.  For purposes of this Agreement, "Disability" shall
               ----------                                                     
     mean (i) a physical or mental infirmity which has been determined to be a
     total and permanent disability under and in accordance with the provisions
     of the Company's Long Term Disability Plan (the "LTD Plan") or (ii) in the
     event the Company does not maintain the LTD Plan at the time of the
     determination of the Executive's Disability, a physical or mental infirmity
     which impairs the Executive's ability to substantially perform duties of
     the type performed by the Executive prior to the onset of the infirmity,
     which impairment continues for a period of at least one hundred eighty
     (180) consecutive days.

2.   Section 3.2(b)(ii) of the Agreement is hereby amended to read in its
     entirety as follows:

               (ii) except if the Executive's employment with the Company shall
     be terminated by the Executive for Good Reason by reason of relocation as
     described in Section 2.4(a)(3) and such relocation is in connection with a
     relocation affecting more than one-half of the employees employed at the
     same metropolitan area as the Executive ("Good Reason for Company
     Relocation"), the Company shall pay the Executive as severance pay and in
     lieu of any further compensation for periods subsequent to the Termination
     Date, in a single payment an amount in cash (the "Severance Amount") equal
     to two (2) times the sum of (A) the highest rate of the Executive's annual
     base salary as in effect at any time within ninety (90) days preceding a
     Change in Control or at any time thereafter ("Base Salary"), (B) the "Bonus
     Amount" (as defined below) and (C) the "Perquisite Amount" (as defined
     below).  If the Executive's employment with the Company shall be terminated
     by the Executive for Good Reason for Company Relocation, the Severance
     Amount shall equal one (1) times the sum of (A) Base Salary, (B) the Bonus
     Amount and (C) the Perquisite Amount.  The term "Bonus Amount" shall 
<PAGE>
 
     mean the highest of the total cash bonuses earned by the Executive pursuant
     to the Annual Plan in any of the three fiscal years of the Company
     immediately preceding the fiscal year in which the Termination Date occurs
     (or such lesser number of full fiscal years during which the Executive was
     employed by the Company); provided, that the Bonus Amount shall not be less
                               --------
     than an amount equal to the Executive's target bonus pursuant to the Annual
     Plan for the fiscal year in which the Termination Date occurs. The
     "Perquisite Amount" shall equal the highest amount paid to the Executive in
     the calendar year ending prior to the Change in Control or in any calendar
     year thereafter in respect of perquisites provided to the Executive,
     including, but not limited to, car allowance, financial counseling, annual
     physical examination and airline membership clubs and shall be in lieu of
     the Company providing such perquisites to the Executive.

3.   Section 3.2(b)(iii) of the Agreement is hereby amended to read in its
     entirety as follows:

               (iii) for a number of months equal to 24 (12 if the Executive's
     employment with the Company shall be terminated by the Executive for Good
     Reason for Company Relocation) (the "Continuation Period"), the Company
     shall at its expense continue on behalf of the Executive and his dependents
     and beneficiaries (to the same extent provided to the dependents and
     beneficiaries prior to the Change in Control) the life insurance,
     disability, medical, dental and hospitalization benefits provided (x) to
     the Executive at any time within ninety (90) days preceding a Change in
     Control or at any time thereafter, or (y) to other similarly situated
     executives who continue in the employ of the Company during the
     Continuation Period. The coverage and benefits (including deductibles and
     costs) provided in this Section 3.2(b)(iii) during the Continuation Period
     shall be no less favorable to the Executive and his dependents and
     beneficiaries, than the most favorable of such coverages and benefits
     during any of the periods referred to in clauses (x) and (y) above. The
     Company's obligation hereunder with respect to the foregoing benefits shall
     be limited to the extent that the Executive obtains any such benefits
     pursuant to a subsequent employer's benefit plans, in which case the
     Company may reduce the coverage of any benefits it is required to provide
     the Executive hereunder as long as the aggregate coverages and benefits of
     the combined benefit plans is no less favorable to the Executive than the
     coverages and benefits required to be provided hereunder. This Subsection
     (iii) shall not be interpreted so as to duplicate any benefits to which the
     Executive or his dependents may be entitled (without having to pay
     additional charges) under any of the Company's employee benefit plans,
     programs or practices following the Executive's termination of employment,
     including without limitation, retiree medical and life insurance benefits.

4.   Section 3.2(b)(iv) of the Agreement is hereby amended to read in its
     entirety as follows:

               (iv)  the Company shall pay in a single payment an amount in cash
     equal to the excess of (A) the actuarial equivalent of the aggregate
     retirement benefit the Executive would have been entitled to receive under
     the SERP, the Scientific-Atlanta, Inc. Retirement Plan and Trust (the
     "Retirement Plan") and the Scientific-Atlanta, Inc. Restoration Retirement
     Plan (the "Restoration Plan") had (w) the Executive remained employed by
     the Company for an additional two (2) complete years of credited service
<PAGE>
 
     (one (l) complete year of credited service if the Executive's employment
     with the Company shall be terminated by the Executive for Good Reason for
     Company Relocation) and his age had increased by the such two (2) years
     (one (1) year if the Executive's employment is terminated by the Executive
     for Good Reason for Company Relocation), (x) he retired at such increased
     age, (y) his annual compensation during such period been equal to his Base
     Salary and the Bonus Amount (but only to the extent that the bonuses which
     are included in the Bonus Amount are includible in compensation for
     purposes of the Retirement Plan, the SERP and the Restoration Plan), and
     (z) he been fully (100%) vested in his benefit under each such retirement
     plan, over (B) the actuarial equivalent of the aggregate retirement benefit
     the Executive is actually entitled to receive under such retirement plans.
     For purposes of this Subsection (iv), "actuarial equivalent" shall be
     determined as of the Executive's date of termination of employment, based
     on the 1983 Unloaded Group Annuity Mortality Table weighted 50% male and an
     interest rate of 8.0%.

5.   Section 6 of the Agreement is hereby amended to read in its entirety as
     follows:

          6.   Gross-Up.
               ---------

               (a)  Whether or not the Executive becomes entitled to the
     Severance Amount, if any of the payments or benefits received or to be
     received by the Executive in connection with a Change in Control or the
     Executive's termination of employment (whether pursuant to the terms of
     this Agreement or any other plan, arrangement or agreement with the
     Company, any Person whose actions result in a Change in Control or any
     Person affiliated with the Company or such Person) (such payments or
     benefits, excluding the Gross-Up Payment, being hereinafter referred to as
     the "Total Payments") will be subject to any excise tax (the "Excise Tax")
     under Section 4999 of the Internal Revenue Code of 1986, as amended (the
     "Code"), the Company shall pay to the Executive an additional amount (the
     "Gross-Up Payment") such that the net amount retained by the Executive,
     after deduction of any Excise Tax on the Total Payments and any federal,
     state and local income and employment taxes and Excise Tax upon the Gross-
     Up Payment, shall be equal to the Total Payments.

               (b)  For purposes of determining whether any of the Total Payment
     will be subject to the Excise Tax and the amount of such Excise Tax, (i)
     all of the Total Payments shall be treated as "parachute payments" (within
     the meaning of section 280G(b)(2) of the Code) unless, in the opinion of
     tax counsel ("Tax Counsel") reasonably acceptable to the Executive and
     selected by the accounting firm which was, immediately prior to the Change
     in Control, the Company's independent auditor (the "Auditor"), such
     payments or benefits (in whole or in part) do not constitute parachute
     payments, including by reason of section 280G(b)(4)(A) of the Code, (ii)
     all "excess parachute payments" within the meaning of section 280G(b)(4)(1)
     of the Code shall be treated as subject to the Excise Tax unless, in the
     opinion of Tax Counsel, such excess parachute payments ( in whole or in
     part) represent reasonable compensation for services actually rendered
     (within the meaning of section 280G(b)(4)(B) of the Code) in excess of the
     "base amount" (as defined in section 280G(b)(3) of the Code) allocable to
     such 
<PAGE>
 
     reasonable compensation, or are otherwise not subject to the Excise Tax,
     and (iii) the value of any noncash benefits or any deferred payment or
     benefit shall be determined by the Auditor in accordance with the
     principles of sections 280G(d)(3) and (4) of the Code. For purposes of
     determining the amount of the Gross-Up Payment, the Executive shall be
     deemed to pay federal income tax at the highest marginal rate of federal
     income taxation in the calendar year in which the Gross-Up Payment is to be
     made and state and local income taxes at the highest marginal rate of
     taxation in the state and locality of the Executive's residence on the
     Termination Date (or if there is no Termination Date, then the date on
     which the Gross-Up Payment is calculated for purposes of this Section 6),
     net of the maximum reduction in federal income taxes which could be
     obtained from deduction of such state and local taxes.

               (c)  In the event that the Excise Tax is finally determined to be
     less than the amount taken into account hereunder in calculating the Gross-
     Up Payment, the Executive shall repay to the Company, within five (5)
     business days following the time that the amount of such reduction in the
     Excise Tax  is finally determined, the portion of the Gross-Up Payment
     attributable to such reduction (plus that portion of the Gross-Up Payment
     attributable to the Excise Tax and federal, state and local income and
     employment taxes imposed on the Gross-Up Payment being repaid by the
     Executive), to the extent that such repayment results in a reduction in the
     Excise Tax and a dollar-for-dollar reduction in the Executive's taxable
     income and wages for the purposes of federal, state and local income and
     employment taxes, plus interest on the amount of such repayment at 120% of
     the rate provided in section 1274(b)(2)(B) of the Code.  In the event that
     the Excise Tax is determined to exceed the amount taken into account
     hereunder in calculating the Gross-Up Payment (including by reason of any
     payment the existence or amount of which cannot be determined at the time
     of the Gross-Up Payment), the Company shall make an additional Gross-Up
     Payment in respect of such excess (plus any interest, penalties or
     additions payable by the Executive with respect to such excess) within five
     (5) business days following the time that the amount of such excess is
     finally determined.  The Executive and the Company shall each reasonably
     cooperate with the other in connection with any administrative or judicial
     proceedings concerning the existence or amount of liability for Excise Tax
     with respect to the Total Payments.

               (d)  In the event that the Company is party to a transaction
     which is otherwise intended to qualify for "pooling of interests"
     accounting treatment, then (i) this Section 6 shall, to the extent
     practicable, be interpreted so as to permit such accounting treatment, and
     (ii) to the extent that this Section 6 disqualifies the transaction as a
     "pooling" transaction, this Section 6 shall be null and void as of the date
     hereof and the Board shall make all reasonable efforts to establish an
     alternative method of providing the Executive with the same benefit
     provided in this Section 6 (or a lesser benefit, if the same benefit is not
     feasible).  All determinations under this Section 6(d) shall be made by the
     accounting firm whose opinion with respect to "pooling of interests" is
     required as a condition to the consummation of such transaction.

     ascribed to them in the Agreement.

     full force and effect as if this Amendment had never been executed.

                  RETIREMENT PLAN FOR NON-EMPLOYEE DIRECTORS
                  ------------------------------------------


                                          As Amended, Effective February 6, 1999

1.   PURPOSE

     The purpose of this plan ("Plan") is to enhance the ability of Scientific-
Atlanta, Inc. ("Company") to attract and retain the service of experienced, able
and knowledgeable persons to serve as members of the Company's board of
directors ("Board") over a substantial period of years during which the full
benefit of their capabilities can be realized to further the growth and
profitability of the Company and return to the shareholders.

2.   ADMINISTRATION

     The Plan shall be administered by a Plan Administrator, who shall be
appointed by the Board.  In addition to the duties stated elsewhere in the Plan,
the Plan Administrator shall have full authority, consistent with the Plan, to
interpret the Plan and to make all determinations necessary or desirable for the
administration of the Plan.

3.   ELIGIBLE PARTICIPANTS

     Each person who is or becomes a member of the Board on or after the
effective date of this Plan but before January 1, 1997, and who has never been a
participant in an employee retirement plan of the Company shall be deemed a
participant in this Plan after having been a member of the Board for thirty-six
consecutive months (a "Participant").  Each person who was a Participant in the
Plan as of January 1, 1997 (the "Conversion Date"), and who was not already
receiving retirement benefits under the Plan as of the Conversion Date, shall,
on or before September 1, 1997, make an election as to whether he or she desires
(a) to continue as a Participant under this Plan, or (b) to discontinue
participation in this Plan and to receive in lieu thereof (1) annual grants of
retirement awards (currently 1,500 shares of the Company's common stock), under
the terms of the Stock Plan for Non-Employee Directors, and (2) a lump sum
                                                        ---               
distribution equal to the greater of either (i) the present value, actuarially
                                     ------                                   
determined by the Company as of the Conversion Date, of the retirement benefits
of such Participant under this Plan through the Conversion Date, reduced by the
                                                                 ----------    
present value, actuarially determined by the Company, as of the Conversion Date,
of the stream of annual grants of retirement awards described under clause (1)
above through such Participant's Normal Retirement Date, or (ii) an amount equal
                                                         --                     
to the value of 750 shares of the Company's common stock. $.50 par value (at the
closing price on the Conversion Date) multiplied by such Participant's total
                                      -------------                         
years of service as a director, as of the Conversion Date, which lump sum
distribution shall be converted, under the terms of the Stock Plan for Non-
Employee Directors, into shares of the Company's common stock, $.50 par value,
at the fair market value on the Conversion Date.  Participants electing to
receive a lump sum distribution shall be also entitled to receive a further
distribution in the form 
<PAGE>
 
of shares to be issued under the Stock Plan for Non-Employee Directors, upon the
death of such Participant, such further distribution to be equal to the
difference, if any, between (a) the value of the spousal benefits otherwise
payable to the spouse of a Participant under the provisions of paragraph 7
below, and (b) the assumed value (as defined in the assumptions approved by the
       --- 
Board) of the lump sum distribution to such Participant described above plus the
                                                                        ----
annual retirement awards granted to such Participant under the Stock Plan for
Non-Employee Directors prior to his or her death. Except to the extent otherwise
provided in the preceding sentence, individuals who are Participants under this
Plan as of the Conversion Date, and who elect on or before September 1, 1997, to
receive the lump sum distribution described above, shall cease to be
Participants under this Plan, effective as of the Conversion Date.

calendar month in which a Participant attains the age of sixty-five (65) years

Participant in accordance with paragraph 6 below.

     (b) A Participant's "Early Retirement Date" is the first day of the
calendar month designated by a Participant in accordance with paragraph 6 below,
prior to the Normal Retirement Date, on or after the month in which a
Participant attains the age of fifty-five (55) years.

5.   RETIREMENT BENEFIT

     (a) The annual retirement benefit payable to any Participant who retires on
the Normal Retirement Date, or any date thereafter, will be an amount equal to
(i) the regular annual retainer paid by the Company to each director for the

(ii) the value, as of the date of grant, of the shares of the Company's Common
Stock granted to the Participant as a "Stock Award" under the Company's Stock
Plan for Non-Employee Directors during the last fiscal year of the Company that
the Participant served as a director.  The "regular annual retainer" as used in
the preceding sentence means the annual retainer received by each director of
the Company, excluding any committee chair annual retainer, meeting fees and
other fees received by a director; and, if the Participant elects to receive all
or a portion of his or her annual retainer in the form of shares of the
Company's common stock under the Company's Stock Plan for Non-Employee
Directors, any portion of such annual retainer received in shares shall be
included in the definition of "regular annual retainer."

     (b) The annual early retirement benefit payable to any Participant who

             64                     .933                                   
             63                     .867                                   
             62                     .800                                   
             61                     .733                                   
             60                     .667                                   
             59                     .633                                   
             58                     .600                                   
             57                     .567                                   
             56                     .533                                   
             55                     .500                                    

     If a Participant's age at the Early Retirement Date falls between any two
of these ages, these factors shall be adjusted by straight-line interpolation.

     (c) No retirement benefit will be payable to any person who is a member of
the Board for less than thirty-six (36) consecutive months.

6.   BENEFIT PAYMENTS

     A Participant may retire by written notice to the Plan Administrator or the
Secretary of the Company, designating a retirement date in accordance with
paragraph 4 above.  Retirement benefit payments will be payable on the first day
of each calendar quarter following retirement or in accordance with such other
schedule of payments as may be requested by the Participant and approved by the
Board.  Benefit payments will continue to be paid to the Participant for the
remainder of the Participant's life.  Notwithstanding the foregoing, in lieu of
the normal form of payment otherwise provided under this Plan, the Plan
Administrator may direct, in its sole and absolute discretion, that benefits
shall be paid in a single sum that is the Actuarial Equivalent of the annual
benefit payable to the Participant or, in the event of the Participant's death,
to his or her surviving spouse.

7.   SPOUSAL BENEFITS

     Should a Participant die before retirement benefits have begun to be paid
to the Participant under this Plan, the Participant shall be deemed to retire on
the later of (i) the day before his/her death, or (ii) the first day of the
first calendar month thereafter in which the Participant would have attained the
age of fifty-five (55), and the Participant's surviving spouse, if any, shall be
entitled to a benefit equal to the benefit that would have been paid to the

                                       3
<PAGE>
 
Participant.  If the Participant dies after retirement benefits have commenced,
the Participant's surviving spouse shall be entitled to annual benefit payments
equal to the annual benefit previously payable to the Participant.  In each
case, the benefit shall continue for the lesser of (i) ten years or (ii) a
number of years equal to the number of years that the Participant was a member
of the Board; provided, however, that payments shall not continue after the
death of the spouse.

8.   DISABILITY

     Should a Participant become totally and permanently disabled prior to
retirement for a period of six (6) consecutive months while a member of the
Board and the Board determines that such disability will continue, the
Participant will be deemed to have retired on the first day of the calendar
month following the month in which the Board makes such determination and the
age of the Participant on such retirement date shall be deemed the older of (i)
fifty-five (55), or (ii) the Participant's actual age on that date.  Payments
will be made on the same basis as described in Sections 5, 6, and 7 above.

9.   CHANGE OF CONTROL

     Notwithstanding anything contained in this Plan to the contrary, the
provisions of this paragraph 9 shall apply to any Participant whose membership
on the Board ends before a Change of Control occurs or who is a member of the
Board on the date that a Change of Control occurs and who ceases within twenty-
four (24) months after a Change of Control to be a member of the Board for any
reason.

     (a) Each such Participant shall be immediately vested in his or her
retirement benefit payable under this Plan.

     (b) The Company shall contribute to the trust maintained pursuant to the
Scientific-Atlanta, Inc. Benefits Protection Trust Agreement a lump sum amount
equal to the Actuarial Equivalent of the Participant's retirement benefit.  This
lump sum payment to the trust shall be due on the later of (i)  the date when
the Change of Control occurs or (ii)  the date the Participant ceases to be a
member of the Board.  The retirement benefit of a Participant who ceases to be a
member of the Board within twenty-four (24) months after a Change of Control
shall be computed as if the Participant would retire on the first day that he or
she is eligible to retire (whether an Early Retirement Date or a Normal
Retirement Date)  following the Change of Control and the end of his or her
membership on the Board.  Any retirement benefits to which the Participant is
entitled under the terms of this Plan shall be payable from the trust, except to
the extent that the benefits are paid from the general assets of the Company.

     (c) Notwithstanding the foregoing, in lieu of the form of payment otherwise
provided for in this paragraph 9, the Plan Administrator may direct, in its sole
and absolute discretion, that upon a Change of Control benefits under this Plan
shall be paid in a single lump sum that is the 

                                       4
<PAGE>
 
Actuarial Equivalent of the annual benefits payable to the Participant or, in
the event of the Participant's death, to his or her surviving spouse.

     (d) "Change of Control" means a change of twenty-five percent (25%) or more
of the membership of the Board (excluding membership changes resulting from
normal retirement of directors) within a twenty-four (24) month period following
the acquisition of beneficial ownership by any person or entity, or group of
persons or entities and their affiliates acting in concert, of twenty percent
(20%) or more of the voting securities of the Company.  "Affiliates" and
"beneficial ownership" shall be defined in accordance with Rules 12b-2 and 13d-3
of the Securities and Exchange Commission, as the same may from time to time be
amended.

     (e) "Actuarial Equivalent" means the present value of future payments based
on the 1983 Unloaded Group Annuity Mortality Table weighted 50% male and an
interest rate of 8%.

10.  TERMINATION AND AMENDMENT OF THE PLAN

     The Board may terminate the Plan at any time and may amend the Plan from
time to time but no such termination and amendment shall adversely affect the
rights of Participants under the Plan, which shall be deemed fully vested and
irrevocable on the date that a director becomes a Participant in accordance with
paragraph 3 above.

11.  EFFECTIVE DATE

     The effective date of this Plan was February 15, 1989.

To record the adoption of the Plan (as amended and restated) by the Board,
effective as of February 6, 1999, the Company has caused its authorized officers
to execute this Plan and affix the corporate name and seal hereto.

     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.

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.

                                       3

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
          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 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

                                       4
<PAGE>
 
          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.

                                       5
<PAGE>
 
     7.3  PAYMENT UPON A CHANGE IN CONTROL.  Upon a Change in Control, the
          following incentive compensation awards shall be paid:

          7.3.1  Upon a Change in Control, the incentive compensation award for
                 a Plan Year ending prior to the date of the Change in Control
                 for which payment has not previously been made shall be
                 unconditionally payable in cash to each Participant.

          7.3.2  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.

          7.3.3  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
          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.

                                       6
<PAGE>
 
     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 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.

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,

           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

           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

     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

                                       4
<PAGE>
 
           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.

                                       5

     7.3  PAYMENT UPON A CHANGE IN CONTROL.  Upon a Change in Control, the
          following incentive compensation awards shall be paid:

          7.3.1  Upon a Change in Control, the incentive compensation award for
                 a Plan Year ending prior to the date of the Change in Control
                 for which payment has not previously been made shall be
                 unconditionally payable in cash to each Participant.

          7.3.2  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.

          7.3.3  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
          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 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,
                                                              --------  -------

          payment of the benefits payable under the Plan.

     benefit under this Plan shall be subject to anticipation, alienation, sale,
     assignment, pledge, encumbrance or charge, and any attempt to anticipate,

     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,

     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).

ARTICLE IV - COMPENSATION DEFERRAL
- ----------------------------------

4.1  Compensation Deferral Election
     ------------------------------

     A Participant shall effect a Compensation Deferral Election by executing
and submitting to the Plan Committee an Election Form.  Subsequently, the
Company shall defer Election Amounts deferred from the Participant's Awards and
Compensation at the time Compensation would have been paid (or at the time the
right to receive shares of Scientific-Atlanta Common Stock was granted, as
applicable).  Awards may only be deferred into an Award Sub-Account and
Compensation may not be deferred into an Award Sub-Account.  Each Election
Amount shall be deferred for the Deferral Period specified with respect to the
particular Compensation Deferral Election in the Election Form, provided,
however, that the Participants shall not be entitled to defer Retirement Awards
or Lump Sum Distributions (as such terms are defined in the Stock Plan for Non-
Employee Directors) for Deferral Periods that are shorter than the minimum
Deferral Periods for such Awards that are set forth in the Stock Plan for Non-
Employee Directors.  All Compensation Deferral Elections shall apply solely to
Compensation and/or Awards which will be paid (or granted) to a Participant
beginning with the first day of the calendar quarter commencing subsequent to
the calendar quarter in which the Compensation Deferral Election is received;  
provided, however, the Participant must submit the Election Form at least thirty
- --------  -------
(30) days prior to the quarter in which the Participant desires to commence a
deferral. Any Compensation Deferral Election will apply only to Compensation
and/or Awards paid (or granted) during the Plan Year in which the election
becomes effective. A Participant may revise or change any election contained in
any Election Form, other than the Election Amount, by submitting to the Plan
Committee a request for such a revision or change and obtaining the Plan
Committee's approval of such revision or change at least ninety (90) days prior
to the effective date of such revision or change.

4.2  Election Amounts
     ----------------

     Each Election Amount specified by a Participant on an Election Form with
respect to any Plan Year shall state in percentages the amount (and, to the
extent applicable, the right to receive a specific number of shares of
Scientific-Atlanta Common Stock), if any, which the Participant wishes to defer.
An election to defer Compensation must equal a minimum of five percent up to a
maximum of one hundred percent, in increments of five percentage points, of the
Compensation which the Participant may be paid during the Plan Year.  As to
Awards, the election must be in whole shares, with no right to receive
fractional shares being deferred.

4.3  Investment Election
     -------------------

     A Participant shall specify in his or her Compensation Deferral Election
the percentage of the Election Amount to be credited to an Interest Sub-Account,
a Phantom Stock Sub-Account or a Split-Dollar Insurance Sub-Account, and the
number of shares to be credited to an Award Sub-Account.  Awards may only be
credited into an Award Sub-Account, and Compensation may not be credited into an
Award Sub-Account.

4.4  Deferral Period

     With the exception of any amounts deposited into a Split-Dollar Insurance
Sub-Account, a Participant shall irrevocably specify in his or her Compensation
Deferral Election a Deferred Benefit Commencement Date for all of the Election
Amount to be deferred pursuant to such Compensation Deferral Election, which
date shall be (i)  a set date which is no earlier than July 1 of the calendar
year following the end of the Plan Year in which the Election Amount is
deferred; (ii) the Participant's Retirement; or (iii) a date which is either the
fifth or the tenth anniversary following the date of the Participant's
Retirement.  In the case of Awards which have minimum Deferral Periods that are
required under the terms of the Stock Plan for Non-Employee Directors, the above
limitations shall apply, and the Participant shall also be required to elect a
Deferral Period that complies with the minimum Deferral Periods required under
the Stock Plan for Non-Employee Directors.

4.5  Deferred Benefit Commencement Date; Method of Payment and Issuance
     ------------------------------------------------------------------

     Except as otherwise provided in Article VI hereof, the Election Amounts
that accumulate in a Deferred Benefit Account as a result of a Participant's
making a Compensation Deferral Election will be paid (or issued, in the case of
deferred Awards) by the Company to the Participant in the manner and commencing
on the Deferred Benefit Commencement Date designated with respect to the
Compensation Deferral Election in an Election Form.

     (a)  Method of Cash Payments:  Except as otherwise provided in Article VI
          -----------------------                                             
     hereof, the Participant may elect to receive payment of the Deferred
     Benefits held in the form of cash, which Deferred Benefits are attributable
     to a Compensation Deferral Election and which are held in an Interest Sub-
     Account or a Phantom Stock Sub-Account, pursuant to one of the following
     methods:

          (1)  Annual, semi-annual or quarterly installments payable over a
          five, ten or fifteen year period, and commencing on the respective
          Deferred Benefit Commencement Date; or

          Deferred Benefit Account, determined as of and payable on the Deferred
          Benefit Commencement Date.

     (b)  Method of Issuance of Shares:  Except as otherwise provided in Article
          ----------------------------                                          
     VI hereof, the Participant may elect to receive issuance of the Deferred
     Benefits held in the form of shares of Scientific-Atlanta Common Stock,
     which Deferred Benefits are attributable to a Compensation Deferral
     Election and which are held in an Award Sub-Account, pursuant to one of the
     following methods:

          (1)  Annual, semi-annual or quarterly issuance of shares of

          ten or fifteen year period, and commencing on the respective Deferred
          Benefit Commencement

                                       6
<PAGE>
 
          Date; provided, however, that no fractional shares of Scientific-
                --------  -------   
          Atlanta Common Stock will be issued; or

          (2)  A single issuance of all shares subject to the specific Award 
          Sub-Account, determined as of and payable on the Deferred Benefit
          Commencement Date.

     (c)  Change in Payment or Issuance Method.  A Participant may change the
          ------------------------------------                               
     method of payment (or method of issuance of shares) selected, which method
     was selected pursuant to the terms of subsection (a) or subsection (b)
     above, as applicable, with respect to a Compensation Deferral Election by
     submitting a request in writing to the Plan Committee.  Prior to a change
     in the method of payment or a change in the method of issuance of shares
     becoming effective, the Plan Committee must approve such change.
     Participants may not move Deferred Benefits from one Sub-Account to another
     Sub-Account, except that Participants may move Deferred Benefits from an
     Interest Sub-Account to a Split-Dollar Insurance Sub-Account by notifying
     the Plan Committee in writing and designating in such notification the date
     upon which such Deferred Benefits are to be moved.

4.6  Designation of Beneficiaries
     ----------------------------

     A Participant shall designate a Beneficiary with respect to each
Compensation Deferral Election and may change the Beneficiary designation with
respect to any Compensation Deferral Election at any time by submitting to the
Plan Committee a revised Beneficiary designation in writing reflecting the
change.

ARTICLE V - DEFERRED BENEFIT ACCOUNTS
- -------------------------------------

5.1  Deferred Benefit Accounts
     -------------------------

     The Company shall cause to be established and maintained a separate
Deferred Benefit Account, and within each such Deferred Benefit Account an
Interest Sub-Account, a Phantom Stock Sub-Account, a Split-Dollar Insurance Sub-
Account and an Award Sub-Account with respect to each Compensation Deferral
Election.  The Company shall credit the Election Amount deferred pursuant to
each such election to the Participant's appropriate Deferred Benefit Account,
and to the Interest Sub-Account, Phantom Stock Sub-Account, a Split-Dollar
Insurance Sub-Account  and Award Sub-Account as specified in the Election, as of
the date deferred from Participant's Compensation as provided in Section 4.1
hereof.

5.2  Interest Sub-Account
     --------------------

     Except as otherwise provided by Section 6.2(a) hereof, interest shall
accrue at the Plan Interest Rate on any amounts credited to an Interest Sub-
Account from the date on which the amount is credited until it is paid to the
Participant, and shall be credited and compounded weekly.

                                       7
<PAGE>
 
5.3  Phantom Stock Sub-Account
     -------------------------

     If a Participant elects all or a portion of the Election Amount to be
credited to the Phantom Stock Sub-Account, the amount so credited shall, solely
for purposes of determining the value of the Phantom Stock Sub-Account, be
deemed to be a number of shares of Scientific-Atlanta Common Stock determined as
follows:

     (a)  Conversion into Scientific-Atlanta Common Stock:  The amount credited
          -----------------------------------------------                      
     to the Phantom Stock Sub-Account shall be converted on the date of such
     credit into an equivalent number of hypothetical shares of Scientific-
     Atlanta Common Stock (including hypothetical fractional shares) by dividing
     the amount credited by the average closing price of Scientific-Atlanta
     Common Stock, as reported on the composite tape of the New York Stock
     Exchange, for the 20 business days immediately preceding the last day of
     the month prior to the month in which such amount is credited.

     (b)  Deemed Reinvestment of Dividends:  The number of hypothetical shares
          --------------------------------                                    
     of Scientific-Atlanta Common Stock credited to a Participant's Phantom
     Stock Sub-Account shall be increased on each date that a dividend is paid
     on Scientific-Atlanta Common Stock. The number of additional hypothetical
     shares of Scientific-Atlanta Common Stock credited to a Participant's
     Phantom Stock Sub-Account as a result of such increase shall be determined,
     first, by multiplying the total number of hypothetical shares of
     Scientific-Atlanta Common Stock credited to such Sub-Account immediately
     before such increase by the amount of the dividend paid per share of
     Scientific-Atlanta Common Stock on the dividend payment date, and, then, by
     dividing the product so determined by the closing sale price of Scientific-
     Atlanta Common Stock on the composite tape of the New York Stock Exchange
     on the dividend payment date (or if there was no reported sale of
     Scientific-Atlanta Common Stock on such date, on the next preceding day on
     which there was such a reported sale).

     (c)  No Rights as Shareholder:  At no time shall the hypothetical shares
          ------------------------                                           
     credited to a Phantom Stock Sub-Account be considered as actual shares of
     Scientific-Atlanta Common Stock, and a Participant shall have no rights as
     a shareholder of the Company by virtue of such hypothetical shares.

5.4  Award Sub-Account
     -----------------

     If a Participant elects that an Award be deferred and credited to an Award
Sub-Account, such Award will remain in such Award Sub-Account until the Deferred
Benefit Commencement Date related to such Award Sub-Account occurs.  No interest
will accrue on the Award in such Award Sub-Account, but amounts equivalent to
the dividends that would have been paid if the shares had been issued will
accrue on such Awards ("Accrued Dividends"). Upon accrual, such Accrued
Dividends will be placed in an Interest Sub-Account.  A Participant shall not
have any rights as a shareholder of the Company while an Award is held in an
Award Sub-Account.

                                       8
<PAGE>
 
5.5  Split-Dollar Insurance Sub-Account
     ----------------------------------

     Amounts credited to a Split-Dollar Insurance Sub-Account shall be used to
pay premiums on life insurance insuring the life of the Participant, or, at the
Participant's election, the lives of the Participant and his or her spouse on a
joint and survivor basis, pursuant to such policies of insurance, and with such
insurers, as the Plan Committee may determine from time to time.  The Company
shall be the owner of such insurance policy or policies, and the proceeds
thereof shall be payable as provided in an Endorsement Split-Dollar Agreement to
be entered into between the Participant and the Company.

5.6  Determination of Account Balance
     --------------------------------

     (a)  As of each Determination Date, the current balance of a Participant's
     Deferred Benefit Account shall be the sum of (i) the balance credited to
     the Interest Sub-Account as of the immediately preceding Determination
     Date, plus any Compensation deferred by such Participant and credited to
     such Interest Sub-Account since the previous Determination Date, plus the
     amount of interest credited to such Interest Sub-Account since the
     preceding Determination Date, plus (ii) the value of the hypothetical
                                   ----                                   
     shares of Scientific-Atlanta Common Stock, determined as set forth in
     Section 5.3(a) above, in the Phantom Stock Sub-Account at that time,
     including deferred amounts credited to that Sub-Account since the last
     Determination Date and deemed reinvestment, if any, of dividends since the
     last Determination Date, plus (iii) the number of shares the Participant
                              ----                                           
     has the right to receive under Awards credited to the Award Sub-Account and
     the total Accrued Dividends credited to the Award Sub-Account, as of the
     immediately preceding Determination Date, plus the number of shares the
     Participant has the right to receive under additional Awards and additional
     Accrued Dividends credited to such Award Sub-Account since the previous
     Determination Date, minus any payments to or withdrawals by the Participant
                         -----                                                  
     from the Deferred Benefit Account since the previous Determination Date.

     (b)  The dollar value of the hypothetical shares of Scientific-Atlanta
     Common Stock credited to a Participant's Phantom Stock Sub-Account on any
     date shall be determined by multiplying the number of hypothetical shares
     of Scientific-Atlanta Common Stock credited to such Sub-Account on that
     date by the average closing price of Scientific-Atlanta Common Stock, as
     reported on the composite tape of New York Stock Exchange issues for the 12
     months immediately preceding that date, or for that number of whole months
     for which the hypothetical shares have been credited to such sub-account,
     if less than 12 months.

     (c)  Effect of Recapitalization: In the event of a transaction or event
          --------------------------                                        
     described in this paragraph (c), the number of hypothetical shares of
     Scientific-Atlanta Common Stock credited to a Participant's Phantom Stock
     Sub-Account and the number of shares of Scientific-Atlanta Common Stock
     subject to Awards credited to a Participant's Award Sub-Account shall be
     adjusted in such a manner as the Plan Committee deems equitable. A
     transaction or event is described in this paragraph (c) if and only if (i)
     it is a dividend 

                                       9
<PAGE>
 
     or other distribution (whether in the form of cash, shares, other
     securities, or other property), extraordinary cash dividend,
     recapitalization, stock split, reverse stock split, reorganization, merger,
     consolidation, split-up, spin-off, combination, re-purchase, or exchange of
     shares or other securities, the issuance of warrants or other rights to
     purchase shares or other securities, or other similar corporate transaction
     or event, and (ii) the Plan Committee determines that such transaction or
     event affects the shares of Scientific-Atlanta Common Stock, such that an
     adjustment pursuant to this paragraph (c) is appropriate to prevent
     dilution or enlargement of the benefits or potential benefits intended to
     be made available under this Plan.

5.7  Statement of Accounts
     ---------------------

     Within ninety (90) days after each Determination Date, the Plan Committee
shall submit to each Participant a statement in such form as the Plan Committee
shall deem desirable, setting forth a summary of the Compensation Deferral
Elections made and the current balances of the Deferred Benefit Accounts and
related Sub-Accounts maintained for the Participant as of the Determination
Date.

ARTICLE VI - PAYMENT (AND ISSUANCE) OF DEFERRED BENEFITS
- --------------------------------------------------------

6.1  General
     -------

     Except as otherwise provided herein, Deferred Benefits credited to the
Interest Sub-Account, the Phantom Stock Sub-Account or the Award Sub-Account
shall be payable (and issued, if applicable) to a Participant upon the Deferred
Benefit Commencement Date and pursuant to the manner of payment (or issuance, if
applicable) selected by the Participant on the applicable Compensation Deferral
Election or any permitted modification thereof, pursuant to Section 4.5(c)
hereof.  If the Participant has elected to receive such Deferred Benefits in
installments, the amount payable in the first year of such installments shall be
an amount that will fully amortize the balance in the Participant's Deferred
Benefit Account determined as of the Deferred Benefit Commencement Date over the
five, ten or fifteen year period, based on assumed interest earnings at the Plan
Interest Rate (to the extent applicable) in effect for such first year.
Thereafter, the amount payable (or to be issued) in each succeeding year shall
be adjusted to an amount that will fully amortize the remaining balance in such
Deferred Benefit Account over the remaining years in the aforesaid five, ten, or
fifteen year installment period based on the Plan Interest Rate (to the extent
applicable) for such succeeding year.  Proceeds of life insurance purchased with
amounts credited to the Split-Dollar Insurance Sub-Account shall be payable as
provided in the respective policy or policies and the applicable Endorsement
Split-Dollar Agreement.

6.2  Service Termination
     -------------------

                                       10
<PAGE>
 
     (a)  Upon termination of service as a director prior to the Participant's
     Retirement:

          (1)  the amounts in each of the Participant's Deferred Benefit
          Accounts shall cease to earn interest (to the extent applicable) and
          the balance of each Deferred Benefit Account shall be determined in
          accordance with Article V hereof, and

          (2)  the Company shall pay (or issue, as appropriate) to the
          Participant the balance of each of the Participant's Deferred Benefit
          Accounts 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
          days of the termination.

     (b)  Upon termination of service as a director on the date of the
     Participant's Retirement, the Company will pay (or issue) to such a
     Participant all amounts in his or her Deferred Benefit Accounts in
     accordance with Section 6.1 hereof.

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

     Deferred Benefits shall be paid (or issued, as appropriate) to a
Participant after his or her becoming Totally Disabled, as follows:

     (a)  Upon the determination that a Participant is Totally Disabled, no
     further deferrals will be made from his or her Compensation, and the
     Company shall pay (or issue, as appropriate) to the Participant the balance
     in each of the Participant's Deferred Benefit Accounts as follows:

          (1)  the date of Total Disability shall be deemed to be (i) the
          Deferred Benefit Commencement Date, if the Deferred Benefit
          Commencement Date for one or more Deferred Benefit Accounts is a set
          date prior to the Participant's fifty-fifth birthday and the Total
          Disability occurs before such date, or (ii) the Participant's
          Retirement, for those Deferred Benefit Accounts, if any, for which the
          Deferred Benefit Commencement Date is the Participant's Retirement or
          later;

          (2)  following Total Disability, the amounts in his or her Interest
          Sub-Account shall continue to earn interest, and the hypothetical
          shares in the Phantom Stock Sub-Account shall continue to earn
          dividends, as provided in the Plan, until paid out to the Participant
          as provided herein; and

          (3)  the amount (including shares of Scientific-Atlanta Common Stock)
          in any Deferred Benefit Account shall be payable (or issued) to the
          Participant on the Deferred Benefit Commencement Date which applies to
          such Deferred Benefit Account, taking into consideration the aforesaid
          deemed dates (Section 6.3(a)(1)(i) and (ii)) pursuant to the method(s)
          requested by the Participant in his or her Election Form.

                                       11
<PAGE>
 
     (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 Company.

     (c)  In the event that a Totally Disabled Participant resumes service with
     the Board following his or her Service Termination Date, 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 pursuant to the terms of this Plan.

6.4  Death
     -----

     Deferred Benefits shall be paid (or issued, as appropriate) after the death
of a Participant, as follows:

     (a)  After the death of a Participant, the Company shall pay the amounts
     (or issue shares of Scientific-Atlanta Common Stock, if applicable) 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 Retirement, the Company 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 (or issue the shares held in the Award Sub-Account), in the same
     manner as set forth in Section 6.3(a).

     (c)  If the Participant dies following Retirement or being determined to be
     Totally Disabled but prior to his or her receiving the full payment of all
     Deferred Benefits payable to him or her, the Company shall pay (or issue,
     if appropriate) to the respective Beneficiaries or to the Participant's
     estate, as the case may be, the same Deferred Benefits in the same manner
     as it otherwise would have paid (or issued) 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.

     (e)  If a Beneficiary who is receiving Deferred Benefits pursuant to this
     Plan dies, the remainder of the Deferred Benefits to which such Beneficiary
     was entitled at the time of

                                       12
<PAGE>
 
     his or her death shall continue to be payable to the Beneficiary or to
     beneficiaries designated by such Beneficiary in writing to the Plan
     Committee (or to the Beneficiary's estate or heirs if he or she fails to
     designate a beneficiary or beneficiaries).

ARTICLE VII - PLAN ADMINISTRATION
- ---------------------------------

7.1  Plan Committee
     --------------

     This Plan and all matters related to it shall be administered by the Plan

ARTICLE VIII - PARTICIPANT'S RIGHTS
- -----------------------------------

8.1  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 participation in this Plan upon ten (10) days' prior
written notice to the Participant. In such event, the Participant will not be
entitled to make further Compensation Deferral Elections, but all current
Compensation Deferral Elections shall continue in effect. All Deferred Benefit
Accounts shall be payable as otherwise provided in Article VI hereof.

8.2  Termination of Plan
     -------------------

     The Board of Directors of the Company 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
Company shall pay all Participants their Deferred Benefits as provided in
Section 6.1 and in the Participant's Election Form; provided, however, if this
                                                    -----------------
Plan is terminated within two (2) years after a Change in Control (as defined in
Section 9.4 hereof), each Participant's Deferred Benefits shall be paid in
accordance with either (a) each Participant's "Change in Control Election Form"
(as defined in Section 9.3 hereof), provided such Participant has completed and
submitted such Change in Control Election Form, as required by Section 9.3
hereof, or (b) Participant's original Election Form and in accordance with
Section 6.1 hereof, but only if a Participant has not validly completed and
submitted a Change in Control Election Form. Upon termination of the Plan,
amounts credited to the Deferred Benefit Accounts of each Participant shall
continue to earn interest at the Plan Interest Rate until such amounts are paid
to the Participant.

8.3  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 Company in connection with the liabilities 

                                       13
<PAGE>
 
assumed by the Company pursuant to this Plan shall not be deemed to be held

Beneficiaries or to be security for the performance of the Company's obligations
hereunder but shall be and remain a general asset of the Company.

8.4  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 its 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 (or issuance, if appropriate)
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.

8.5  Cooperation
     -----------

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

ARTICLE IX - CHANGE IN CONTROL
- ------------------------------

9.1  Applicability
     -------------

     Notwithstanding any provision in this Plan to the contrary, the terms of
this Article IX shall apply to any Participant, whether active or inactive.

9.2  Effect of Change in Control
     ---------------------------

     Upon a Change in Control the following shall immediately occur:

     (a)  The Company shall contribute to the trust maintained pursuant to the
     Scientific-Atlanta, Inc. Benefits Protection Trust Agreement a lump sum
     amount equal to each Participant's Deferred Benefit Accounts.  The Company
     shall assign to such trust (i) any split-dollar life insurance policies
     held by the Company, pursuant to Section 5.5 hereof, for the benefit of a
     Participant's beneficiaries; and (ii) any Endorsement Split-Dollar
     Agreements between the Company and a Participant.

     (b)  All Participants shall be deemed to have satisfied the age and service
     requirements in the definition of Retirement in this Plan.

                                       14
<PAGE>
 
     (c)  For any Participant who is a member of the Board on the date that a
     Change in Control occurs and who ceases, within twenty-four (24) months
     after a Change in Control, to be a member of the Board for any reason, the
     Company shall pay such Participant his or her Deferred Benefits in
     accordance with such Participant's Change in Control Election Form, if
     completed and returned pursuant to Section 9.3. If a Participant has not
     completed and returned such Change in Control Election Form, such
     Participant's Deferred Benefits shall be paid in accordance with his
     original Election Form and Article VI hereof.

     (d)  All amounts held in an Interest Sub-Account shall remain in such
     Interest Sub-Account and shall earn interest at the Plan Interest Rate
     until all amounts in such Interest Sub-Account are fully paid.

     (e)  All amounts held in a Participant's Phantom Stock Sub-Account shall be
     valued as of the date of the Change in Control, based on the conversion
     method utilized in Section 5.3(a) hereof, and such amounts shall be
     automatically transferred to an Interest Sub-Account for such Participant
     (and shall earn interest in accordance with Section 9.2(d)).

     (f)  All Awards held in an Award Sub-Account shall be automatically
     converted into the cash value of such Awards on the date of the Change in
     Control and such cash value shall be automatically transferred to the
     Interest Sub-Account (and earn interest in accordance with Section 9.2(d)).
     The cash value of such Awards on the date of the Change in Control shall be
     determined by multiplying the closing price of one (1) share of Scientific-
     Atlanta Common Stock on the business day immediately prior to the date of
     the Change in Control times the number of shares of Scientific-Atlanta
                           -----                                           
     Common Stock that the Participant has a deferred right to receive under his
     Award Sub-Account.

     (g)  All amounts, if any, held in a Participant's Split-Dollar Insurance
     Sub-Account shall be automatically transferred to an Interest Sub-Account
     for such Participant (and shall earn interest in accordance with Section
     9.2(d)). The trust described in Section 9.2(a) shall withdraw from a
     Participant's Interest Sub-Account the amounts required to pay the premiums
     for the split-dollar life insurance held by the trust (pursuant to Section
     9.2(a)) for the benefit of such Participant's beneficiaries.

9.3  Change in Control Election Form
     -------------------------------

     At any time at least ninety (90) days prior to a Change in Control, each
Participant may elect to have his Deferred Benefits paid out after a Change in
Control in a manner different from the manner he previously elected in his
original Election Form.  Each Participant may complete and submit a Change in
Control Election Form and thereby elect to have his or her Deferred Benefits
paid as follows if the Plan is terminated or a Participant's service on the
Board is terminated, within twenty-four (24) months after a Change in Control:
(a) have his Deferred Benefits paid as a lump sum payment, payable within five
(5) days after the date of termination of the Plan or the date of Participant's
termination of service on the Board (whichever occurs 

                                       15
<PAGE>
 
first); or (b) have his Deferred Benefits paid as though his Deferred Benefit
Commencement Date were the date of termination of the plan or the date of
Participant's termination of service on the Board (whichever occurs first); or
(c) have his Deferred Benefits paid as of a specified date (the "Change in
Control Election Form"). As with the original Election Form, Participant may
elect, in his Change in Control Election Form, to have his Deferred Benefits
paid in a lump sum, or in installments over a 5-year period, a 10-year period,
or a 15-year period. For a Change in Control Election Form to be validly
submitted by a Participant, it must be received by the Corporate Secretary of
the Company prior to the deadline specified in the first sentence of this
Section 9.3.

9.4  Definition of Change in Control
     -------------------------------

     For purposes of this Plan, a Change in Control shall mean any of the
following events:

     (a)  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 8.4, 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

     (b)  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 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

     (c)  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 

                                       16
<PAGE>
 
     merger or consolidation, more than eight 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.

     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 acquisition, by reducing the number of Voting Securities outstanding,
increases the proportional number of shares Beneficially Owned by the Subject
Person, provided that if, after a Change in Control would occur (but for the
        --------                                                            
operation of this sentence) as a result of such 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.

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

      The Board of Directors of the Company may amend this Plan in any respect

Atlanta Common Stock may elect to satisfy such withholding requirements by
having the Plan Committee withhold shares otherwise issuable to the Participant,
with the Participant's election being made by delivering to the Plan Committee a
written election stating his or her desire to so satisfy such withholding
requirements.

      To record the adoption of the Plan (as amended and restated) by the Board
on May 12, 1999, the Company has caused its authorized officers to execute this
Plan.

     required for the reduction or withdrawal to be effective.

     Article 4 - Deferred Compensation Account
     -----------------------------------------

4.1  Each Participant's deferred compensation and the interest equivalent
     provided for in paragraph 4.2 below shall be credited on the books of the
     Company to his or her Deferred Compensation Account ("DCA"). Except as
     provided in the following sentences of this paragraph 4.1, a prorata
     portion of the Participant's annual deferred compensation shall be credited
     to the Participant's DCA as of each regular bi-weekly payday. A Participant
     may elect to have all or a portion of his or her deferred compensation for
     a Plan Year withheld from any annual cash bonus awarded to the Participant
     during the year. If the entire amount specified in a Plan Agreement to be
     deferred in a Plan Year has not been credited to a Participant's DCA on or
     before the second regular bi-weekly payday in September of that year, the
     amount yet to be deferred shall be deducted from the Participant's current
     compensation and credited to the Participant's DCA in prorata increments as
     of each regular bi-weekly payday during the remainder of the Plan Year.

4.2  As of the last day of each Plan Year, the amount in a Participant's DCA
     shall be increased by an interest equivalent equal to 14% of the amount in
     such account; provided, however, that if a Participant's employment by
     Scientific-Atlanta or participation in the Plan terminates within less than
     thirty-six (36) months after the

                                       3
<PAGE>
 
     commencement of the Deferral Period for any reason other than death or
     retirement under a Retirement Plan of the Company, the interest equivalent
     credited to that Participant's account shall be reduced for each Plan Year
     to the applicable percentage specified below:

          (a)  Twelve percent (12%) if such termination or withdrawal occurs
     after twenty-four (24) months and prior to thirty-six (36) months of the
     Deferral Period;

          (b)  Ten percent (10%) if such termination or withdrawal occurs after
     twelve (12) months but prior to twenty-four (24) months of the Deferral
     Period;

          (c)  Zero percent (0%) if such termination or withdrawal occurs within
     the first twelve (12) months of the Deferral Period.

4.3  The interest equivalent percentage shall not be reduced if termination of
     employment occurs because of death or retirement under a Retirement Plan of
     the Company.

     Article 5 - Payments
     --------------------

5.1  Subject to paragraph 5.2 below, the amount in a Participant's DCA shall be
     paid in approximately equal semi-annual installments following the Deferred
     Payment Commencement Event ("DPCE") specified below or in accordance with
     such other payment schedule, such as monthly or quarterly, as may be
     specified in a Plan Agreement or requested in writing by Participant and
     approved by the Committee:

          (a)  If the Participant retires under the Company's Retirement Plan,
     the DPCE (Deferred Payment Commencement Event) shall be (i) the
     Participant's actual retirement date, (ii) the date that deferred payments
     are actually made from the Company's Retirement Plan, (iii) the
     Participant's tenth anniversary of participation in the Plan or (iv) the
     Participant's 65th birthday.

          (b)  If the Participant's employment is terminated for any reason
     other than retirement under the Company's Retirement Plan and such
     termination occurs after the end of the Deferral Period, the DPCE shall be
     the first to occur of (i) the Participant's death, (ii) the Participant's
     sixty-fifth (65th) birthday or (iii) the date following the Participant's
     fifty-fifth (55th) birthday on which Participant retires from his or her
     principal occupation or employment (which date shall be established on the
     basis of an

                                       4
<PAGE>
 
     affidavit executed by Participant and such other supporting documentation 
     as the Company may reasonably request).

          (c)  If a Participant withdraws from the Plan or if the Participant's
     employment is terminated for any reason other than retirement under the
     Company's Retirement Plan and such withdrawal or termination occurs before
     the end of the Deferral Period, the DPCE shall be the effective date of
     such withdrawal or termination.

5.2  After the occurrence of the Participant's DPCE, the Company shall make
     payments as follows until the entire amount in the Participant's DCA is
     paid:

          (a)  If the total amount in the DCA is less than $10,000 on the date 
     of the DPCE, the entire amount shall be paid in a lump sum;

          (b)  If the total amount in the DCA on the date of the DPCE is $10,000
     or more but less than $25,000, equal payments shall be made over a five-
     year period.

          (c)  If the total amount in the DCA on the DPCE is $25,000 or more but
     less than $50,000, equal payments shall be made over a ten-year period.

          (d)  If the total amount in the DCA on the DPCE is $50,000 or more, 
     equal payments shall be made over a fifteen-year period.

     Balances remaining in a Participant's DCA on the last day of each calendar
     year shall continue to be credited with an interest equivalent as provided
     herein.

5.3  In the event the Participant dies before receiving the entire amount
     credited to the Participant's DCA, the balance of the DCA at the time of
     his or her death shall be paid to the Participant's Beneficiary. A
     Participant's Beneficiary shall be the person or persons designated by
     written notice, in a form acceptable to the Committee, delivered to the
     Company prior to Participant's death. A Participant may change a
     designation of Beneficiary from time to time by subsequent written notices
     to the Company, in a form acceptable to the Committee, delivered prior to
     Participant's death. If the Participant is an employee of the Company or a
     retiree under the Company's Retirement Plan at the time of his or her death
     and has not designated a Beneficiary pursuant to this Agreement, the
     Beneficiary under this Agreement shall be deemed to be the same as

                                       5

<PAGE>
 
     the beneficiary under the Company-provided life insurance then covering
     Participant as a Scientific-Atlanta employee or retiree. In the absence of
     such designation, payment shall be made to the Participant's personal
     representative for distribution as an asset of Participant's estate in
     accordance with applicable law. The time and form of payments specified
     elsewhere herein shall not be altered on account of Participant's death,
     provided, however, that at the request of Participant's Beneficiary or
     --------  -------
     personal representative, the Committee may authorize and direct an
     acceleration of such payments, including a lump sum payment, if it should
     choose in its absolute discretion to do so.

     Article 6 - Death Benefits
     --------------------------

6.1  If a Participant dies while an employee of the Company and prior to
     withdrawal from the Plan, or after retirement under the Company's
     Retirement Plan and prior to the receipt of any payments under Article 5
     above, the Participant's DCA will be credited as of the date of his or her
     death with an amount, if any, necessary to cause the balance in the DCA
     after such credit to be equal to five times the average of the four annual
     amounts specified in the Participant's Plan Agreement to be deferred during
     the Deferral Period; provided, however, that if the deceased Participant's
     employment by the Company had terminated by reason of Participant's
     retirement under the Company's Retirement Plan prior to the end of the
     Deferral Period, the amount credited under this Article 6 shall not exceed
     five times the Participant's annual average compensation actually deferred
     pursuant to this Plan during the Plan Years preceding the termination of
     Participant's employment.

6.2  No amount will be credited to the Participant's DCA under this Article 6 
     if:

          (a)  the balance in the Participant's DCA on the date of his or her
     death is equal to or exceeds five times the average of the four annual
     amounts specified in the Participant's Plan Agreement to be deferred during
     the Deferral Period;

          (b)  prior to death, the Participant had withdrawn from the Plan, the
     employment of Participant had been terminated by the Company for any reason
     other than retirement under the Company's Retirement Plan, or payments
     under Article 5 above have commenced;

                                       6
     
<PAGE>
 
          (c)  the Participant's death is the result of suicide within two years
     after execution of the Plan Agreement:

          (d)  the Participant's death is determined to have resulted from a
     bodily or mental cause or causes, information about which was withheld,
     knowingly concealed, or falsely provided by the Participant in response to
     a request by the Company to furnish evidence of good health; or

          (e)  proof of death in a form determined acceptable by the Committee 
     is not furnished.

     Article 7 - Total Disability
     ----------------------------

7.1  If a Participant has entered into a Plan Agreement prior to his or her
     sixtieth (60th) birthday and becomes Totally Disabled while an employee of
     the Company and prior to withdrawal from the Plan or the receipt of any
     payments under Article 5 of the Plan, the Participant shall be entitled to
     receive under the Plan, for so long as such Total Disability shall
     continue, annual disability benefits at a rate equal to one and one-half 
     (1-1/2) times the average of the four annual amounts specified in the
     Participant's Plan Agreement to be deferred during the Deferral Period;
     provided, however, that the disability benefit shall not continue after the
     Participant's sixty-fifth (65th) birthday.

7.2  During the continuation of a Participant's Total Disability that commences
     prior to termination of Participant's employment for any reason, a
     Participant who has not requested withdrawal from the Plan shall continue
     to be deemed a Participant and an employee of the Company and the Company
     shall continue to credit the Participant's DCA with the applicable amount
     of deferred compensation in accordance with the Plan Agreement at each pay
     period as if the Participant were not Totally Disabled.

     Article 8 - Leave of Absence
     ----------------------------

8.1  If a Participant is authorized by the Company for any reason to take a
     temporary leave of absence with Basic Compensation continuation throughout
     the period of absence, the Plan Agreement shall continue in full force and
     effect as if the Participant were not on leave of absence.

8.2  If a Participant is authorized by the Company for any reason to take a 
     temporary leave of absence without pay at any time during

                                       7

<PAGE>
 
     the Deferral Period, the Plan Year in which the leave of absence begins and
     the Deferral Period shall be deemed suspended and no amounts shall be
     credited to the Participant's DCA during such leave of absence. The
     calendar year in which the Participant returns to regular employment by the
     Company shall be deemed a resumption of the Plan Year in which the leave of
     absence began and during the balance of that year a sufficient amount of
     the Participant's Basic Compensation shall be deferred, in approximately
     equal increments on each regular pay day, to cause the amount deferred for
     the Plan Year, as so continued, to be equal to the amount specified in the
     Plan Agreement for that Plan Year. Notwithstanding the foregoing, the
     Company may deem the Participant to have withdrawn from the Plan at such
     time as (i) the Participant's leave of absence continues beyond the period
     authorized by the Company; or (ii) the Company determines that the Deferral
     Period will not be completed within the first seven Plan Years after
     execution of the Plan Agreement.

8.3  For the purposes of this Plan, a Participant's employment by the Company
     shall be deemed to continue throughout the authorized period of any leave
     of absence, paid or unpaid.

     Article 9 - Termination of the Plan
     -----------------------------------

9.1. The Company shall have the right to terminate this Plan and any Plan
     Agreement at any time by written notice to each Participant to that effect;
     provided, however, that no such termination shall affect the rights of any
     Participant who is Totally Disabled on the effective date of termination
     nor the entitlement of any Beneficiary to receive a benefit payable on
     account of the death of any Participant occurring prior to the effective
     date of termination.

9.2  The termination of this Plan or a Plan Agreement by the Company shall be
     deemed a Deferred Payment Commencement Event within the meaning of Article
     5 above.

     Article 10 - Restriction on Alienation of Benefits
     --------------------------------------------------

10.1 No right or benefit under this Plan or a Plan Agreement 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. No right or benefit hereunder shall in any
     manner be liable for or subject to the debts, contracts, liabilities, or
     torts of the person entitled to such benefit.

          Plan are as expressly set forth in this Plan and the Plan Agreement

          furnishing all information requested by the Company related to the
          payment of benefits or any other action within the scope of the
          Company's responsibilities under this Plan. Such information may
          include the taking of a physical examination by Participant.

          Article 12 - Unsecured General Creditor
          ---------------------------------------

12.1      Amounts payable to a Participant shall be paid from the general assets
          of the Company exclusively; provided, however, nothing herein shall
                                      --------  -------

          conclusive and binding upon all persons having or claiming to have any
          right or interest under the Plan.

13.3      No member of the Committee shall be liable for any act of omission of 
          any other member of the Committee, nor for any act or omission

          on his own part, excepting his own wilful misconduct. The Company
          shall indemnify and save harmless the Administrator and each member of
          the Committee against any and all expenses and liabilities arising out
          of or related to his or her acts and omissions related to this Plan,

          kind of benefits from time to time payable to Participants and their
          Beneficiaries and to authorize all disbursements for such purposes.

          Article 14 - General and Miscellaneous
          --------------------------------------

14.1      Nothing in this Plan or in any Plan Agreement shall be construed as a
          contract of continuing employment or as obligating a Participant in

14.3      This Plan and Plan Agreements shall be binding upon the Company, its
          successors and assigns and upon Participant and Participant's
          Beneficiaries, assigns, heirs executors and administrators.

14.4      This Plan and all Plan Agreements shall be interpreted in accordance
          with and governed by the laws of the State of Georgia; provided,
          however, that nothing in this paragraph shall be construed as limiting
          the discretion of the Committee or its power to render final and
          binding judgments and interpretations as provided herein and in Plan

14.6      If any provision of this Plan should be deemed illegal or invalid for

          force and effect and the Plan shall be construed and administered as
          if the illegal or invalid provision had never been included; provided,
          however, that if the essential purpose of the Plan would be frustrated
          by the invalidity or illegality of any provision, the Company may, by
          written notice to Plan Participants, add a replacement provision that
          is valid, conforms to applicable law and has a substantially similar
          effect to the provision determined to be invalid but if the Company
          deems the addition of such a replacement provision to be impossible,
          the Company shall terminate the Plan.

          Article 15 Change in Control
          ----------------------------

15.1      Contrary Provisions. Nothwithstanding anything contained in the Plan
          -------------------
          to the contrary, the provisions of this Article 15 shall govern and
          supersede any inconsistent terms or provisions of the Plan.

15.2      Change in Control. For purposes of this Plan, a "Change in Control" 
          -----------------
          shall mean any of the following events:

               (a)  The aquisition in one or more transactions by any "Person" 
          (as the term person is used for purposes of Section

                                      11
<PAGE>
 
          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 15.2(a), the Voting Securities acquired
          directly from the Company by any Person's 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

               (b)  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

               (c)  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

                                      12
<PAGE>
 
          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 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 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 (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 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.

          No act, nor failure to act, on the Participant's part, shall be 
          considered "willful" unless the Participants has acted, or failed to
                                        

                                      13
<PAGE>
 
          act, with an absence of good faith and without a reasonable belief 
          that action or failure to act was in the best interest of the Company.

15.3      Termination of Employment. Notwithstanding any other provision of this
          -------------------------
          Plan to the contrary, if a Participant's employment with the Company
          or participation in the Plan terminates other than for Cause (as
          defined in paragraph 15.4), and such termination occurs within two
          years following a Change in Control or 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 or (ii) otherwise occurs in
          connection with or in anticipation of a Change in Control:

               (a)  The interest equivalent credited to such Participant's DCA
          shall equal fourteen percent (14%) of the amount in his DCA at the
          close of each Plan Year ending prior to such termination plus a pro
          rata interest equivalent at such rate for the portion of the Plan Year
          in which such termination occurs based on the number of days elapsed
          through the date of termination. This paragraph 15.3(a) shall not be
          applicable if a Paritcipant's employment with the Company or
          participation in the Plan is terminated for Cause and the provisions
          of paragraph 4.2 shall govern the interest equivalent payable to such
          Participant.

               (b)  The amount in the Participant's DCA including the interest
          equivalent determined under paragraph 15.3(a) shall be unconditionally
          payable in cash to the Participant. Unless the Committee directs as
          earlier payment, such amount shall be paid in cash on or before the
          date which is five (5) days following the Termination Date.

15.4      Cause. For purpose of this Plan, a termination for "Cause" is a
          -----
          termination evidenced by a resolution adopted in good faith by two-
          thirds of the Board that the Participant (i) has been convicted of a
          felony, or (ii) has engaged in conduct which constitutes (A) willful
          neglect in carrying out his duties to the Company or (B) willful
          misconduct, in either case, which is demonstrably and materially
          injurious to the Company monetarily or otherwise.

15.5      Continuation of the Plan. For a period of two (2) Years following a
          ------------------------
          Change of Control, The Plan shall not be terminated or

                                      14
<PAGE>
 
          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 of Control),
          nor shall the manner in which the Plan is administered be changed in a
          way that adversely affects the level of participation or the benefits
          accruing to any Participant.

15.6      Amendment or Termination.
          ------------------------

          (i)  This Article 15 shall not be amended or terminated at any time.

          (ii) Any amendment or termination of the Plan prior to a Change in
          Control which (l) 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, shall be null and void and shall
          have no effect whatsoever.

To record the adoption of the Plan (as amended and restated) by the Board,
effective as of February 6, 1999, the Company has caused its authorized officers
to execute this Plan.

defer future Salary may be made either before or during the Plan Year, provided,
however, that any such election must be submitted to the Plan Committee at least
thirty (30) days prior to the applicable fiscal quarter and must apply to at
least the entire fiscal quarter. An election to defer all or a portion of the
payment of any Annual Incentive Plan Payment, a Long-Term Incentive Plan
Payment, Other Incentive Compensation, 1985 Plan Payments or Severance Payments
must be made at least ninety (90) days prior to the date the Participant is
entitled to receive such payment. A Participant may revise or change any
election or instruction contained in any Election Form, other than the Election
Amount, by submitting to the Plan Committee a revised Election Form at least
ninety (90) days prior to the effective date of such revision or change.

     4.2  Election Amounts
          ----------------

     Each Election Amount shall be selected as follows:

     (a)  With respect to Salary, a participant may defer a specified percentage
of the Salary which the Participant will earn and receive during the balance of
the Plan Year, provided, however, that no deferral election with respect to the
current Plan Year may be made after March 31.   Percentage deferral must be an
increment of five percentage points and shall not exceed fifty percent.

     (b)  With respect to an Annual Incentive Plan Payment, a Long-Term
Incentive Plan Payment, Other Incentive Compensation, 1985 Plan Payments or
Severance Payments, a Participant may defer either a specified percentage of the
entire payment or a specified percentage of the payment above a stated dollar
amount; provided, however, that any such percentage must be an increment of five
percentage points.

     4.3  Reduction of Compensation
          -------------------------

     The Employer shall deduct Election Amounts deferred from a Participant's
Salary ratably over each remaining pay period in the Plan Year.  The Employer
shall deduct Election Amounts deferred from an Annual Incentive Plan Payment, a
Long-Term Incentive Plan Payment, Other Incentive Compensation, 1985 Plan
Payments or Severance Payments at the time such payment is otherwise payable.

     4.4  Deferred Benefit Commencement Date
          ----------------------------------

     Except as otherwise provided in Article VI hereof, a Participant may elect
to defer receipt of an Election Amount until the Deferred Benefit Commencement

Dates are (i) a set date which is no earlier than July 1 of the calendar year
following the end of the Plan Year in which the Election Amount is deferred;
(ii) the Participant's Employment Termination Date, or (iii) a date which is
either the fifth or tenth anniversary of the Participant's Employment
Termination Date.  The term "Retirement" used as a designation on any Election
Form for a Deferred Benefit Commencement Date shall mean the Participant's
Employment Termination Date.

     4.5  Manner of Payment
          -----------------

     Except as otherwise provided in Article VI hereof, the Participant may
elect to receive payment of the Deferred Benefits attributable to a Compensation
Deferral Election pursuant to one of the following methods:

     (a)  Annual, semiannual or quarterly installments payable over a five, ten
or fifteen year period, and commencing on the respective Deferred Benefit
Commencement Date; or

     (b)  A single lump sum payment of the entire balance of the respective
Deferred Benefit Account, determined as of and payable on the Deferred Benefit
Commencement Date.

     4.6  Designation of Beneficiaries
          ----------------------------

     A Participant shall designate a Beneficiary with respect to each
Compensation Deferral Election and may change the Beneficiary designation with
respect to any Compensation Deferral Election at any time by submitting a
revised Beneficiary designation in writing reflecting the change to the Plan
Committee.

                     Article V - Deferred Benefit Accounts
                     -------------------------------------

     5.1  Deferred Benefit Accounts
          -------------------------

     The Employer shall cause to be established and maintained a separate
Deferred Benefit Account with respect to each Compensation Deferral Election.
The Employer shall credit the 

                                       6
<PAGE>
 
Election Amount deferred pursuant to each such election to the Participant's
appropriate Deferred Benefit Account as of the date deferred from the
Participant's Compensation as provided in Section 4.3 hereof. The amount
credited to a Participant's Deferred Benefit Account shall equal the Election
Amount deferred reduced by the amount, if any, that the Employer may be required
from time to time to withhold from such Election Amount pursuant to any federal,
state or local law.

     5.2  Accrual of Interest
          -------------------

     Except as otherwise provided by Section 6.2(b) hereof, interest shall
accrue, at the Plan Interest Rate in effect from time to time, on any amounts
credited to a Deferred Benefit Account from the date on which the amount is
credited until it is paid to the Participant, and shall be credited and
compounded weekly.

     5.3  Determination of Account Balance
          --------------------------------

     As of each Determination Date, the current balance of a Participant's
Deferred Benefit Account shall equal (A) the sum of (i) the balance of such
Deferred Benefit Account as of the immediately preceding Determination Date,
(ii) any Compensation deferred by such Participant to such Deferred Benefit
Account since the previous Determination Date and (iii) the amount of interest
credited to such Deferred Benefit Account since the preceding Determination
Date, minus (B) any payments to or withdrawals by the Participant from the
Deferred Benefit Account since the previous Determination Date.

     5.4  Statement of Accounts
          ---------------------

     Within ninety (90) days after each Determination Date, the Plan Committee
shall submit to each Participant a statement in such form as the Plan Committee
shall deem desirable, setting forth a summary of the Compensation Deferral
Elections made and the current balances of the Deferred Benefit Accounts
maintained for the Participant as of the Determination Date.


                   Article VI - Payment of Deferred Benefits
                   -----------------------------------------

     6.1  General
          -------

     Except as otherwise provided herein, Deferred Benefits in each Deferred
Benefit Account shall be payable to a Participant upon the Deferred Benefit
Commencement Date for such Account and pursuant to the manner of payment
selected by the Participant on the applicable Election Form or any permitted
modification thereof.  If the Participant has elected to receive such Deferred
Benefits in installments, the amount payable in the first year of such
installments shall be an amount that will fully amortize the balance in the
Participant's Deferred Benefit Account determined as of the Deferred Benefit
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.
Thereafter, the amount payable in each succeeding year shall be adjusted to an
amount that will fully amortize the remaining balance in such Deferred Benefit
Account over the remaining 

                                       7
<PAGE>
 
years in the aforesaid five, ten, or fifteen year installment period based on
the Plan Interest Rate for such succeeding 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, the amount in each Deferred Benefit Account shall be payable to the
Participant either (i) in the manner specified by the Participant in his or her
Election Form to apply in the event of his or her involuntary termination by the
Employer; or (ii) if no such specification is made, on the Deferred Benefit
Commencement Date that applies to such Deferred Benefit Account, pursuant to the
method requested by the Participant in his or her Election Form.

     (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)  Upon the voluntary termination of employment with the Employer by a
Participant who is fifty-five years or older the Employer will pay out to such
Participant all amounts in his or her Deferred Benefit Account in accordance
with the instructions in the applicable Election Form.

     (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, voluntarily or involuntarily, 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 Plan, 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 

                                       8
<PAGE>
 
Company's then outstanding voting securities (the "Voting Securities"),
provided, however, that for purposes of this Section 6.2(d)(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.

     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

                                       9
<PAGE>
 
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.

     (e)  Other provisions of this Plan to the contrary notwithstanding, this
Plan may not be modified, amended or terminated within two (2) years after a
Change in Control.

     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), unless the Participant
has specified in his or her Election Form a different manner of payment.

     (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 

                                       10
<PAGE>
 
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.

     (e)  If a Beneficiary who is receiving Deferred Benefits pursuant to this
Plan dies, the remainder of the Deferred Benefits to which such Beneficiary was
entitled at the time of his or her death shall continue to be payable to the
beneficiary or beneficiaries designated by such Beneficiary in writing to the
Plan Committee (or to the Beneficiary's estate or heirs if he or she fails to
designate a beneficiary or beneficiaries).

                      Article VII - Hardship Withdrawals
                      ----------------------------------

     7.1  Hardship Withdrawals.  A participant may request a Hardship Withdrawal
          ---------------------                                                 
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 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

                                       11
<PAGE>
 
     (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.

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

     8.1  Plan Committee
          --------------

     This Plan and all matters related to it shall be administered by the Plan
Committee.  The Plan Committee shall have the authority to interpret the

determination by the Plan Committee shall be conclusive and binding on all
persons.

     8.2  Claim Procedures
          ----------------

     Any Participant or Beneficiary claiming a benefit, or requesting an
interpretation, any information, or a ruling under this Pan shall present the

within thirty (30) days from the date on which it receives the claim or request.


                       Article IX - Participant's Rights
                       ---------------------------------

     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 participation in this Plan upon ten (10) days' prior
written notice to the Participant.  In such event, the Participant will not be
entitled to make further Compensation Deferral Elections, but all current
Compensation Deferral Elections shall continue in effect.  All Deferred Benefit
Accounts shall be payable as otherwise provided in Article VI hereof.

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

     Subject to the provisions of Section 6.2(e) of this 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 6.2(a) as if the employment of the Participant by the Company had
been involuntarily 

                                       12
<PAGE>
 
terminated. Upon termination of the Plan, amounts credited to the Deferred
Benefit Accounts of each Participant shall continue to earn interest at the Plan
Interest Rate until such amounts are paid to the Participant.

     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 Plan 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.

     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.

                                       13
<PAGE>
 
     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

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

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
Commencement Date.

           ---------

     This Plan shall be binding upon and shall inure to the benefit of the
Employer and each Participant hereto, and their respective beneficiaries, heirs,

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

                                  ARTICLE IV

                              RETIREMENT BENEFITS

     4.1  Normal Retirement.
          ------------------

          A Participant who retires from the Company on or after his or her
Normal Retirement Date shall be entitled to receive an annual retirement benefit
(the "Normal Retirement Benefit") for life, equal to the excess of:

          (a)  the Participant's Accrued Benefits determined under Sections 3.1
or 3.2 hereof; over

          (b)  the sum of:

               (i)   the annual retirement benefits payable to the Participant
as a life annuity pursuant to the defined benefit retirement plan of the Company
(as such plan might be amended, supplemented or superseded from time to time)
which is the actuarial equivalent (as defined in Section 5.3) of such
Participant's Pension Equity Account as defined in such plan;

               (ii)  the annual retirement benefits payable to the Participant
pursuant to any employer-funded defined benefit plan maintained by a prior
employer of the Participant, assuming that such benefits are payable in the form
of a single life annuity for the life of the Participant; and

               (iii) the Participant's annual primary insurance amount under the
Federal Social Security Act as in effect on the Participant's Normal Retirement
Date or, if applicable, his date of death.  In determining such amount under
Section 4.2 below for a Participant who severs from service prior to his Normal
Retirement Date, it shall be assumed that the Participant will continue to
receive, until his Normal Retirement Date, annual compensation (which would be
treated as wages for purposes of the Federal Social Security Act) at the same
rate which is in effect immediately prior to his termination of employment.

     4.2  Early Retirement.
          ---------------- 

          (a) A Participant who retires from the Company on or after his or her
Early Retirement Date but prior to his or her Normal Retirement Date shall be
entitled to receive his or her Normal Retirement Benefit commencing on the date
of his or her retirement; provided, however, that such date of commencement may,
                          --------  -------                                     
at the election of the Participant pursuant to 

                                       5
<PAGE>
 
Section 4.3 (or, if the Participant has not made an election, at the election of
the Committee), be deferred to the date that the Participant attains age sixty
(60). If the Participant retires prior to age sixty (60) and begins to receive
benefits under this Plan prior to age sixty (60), such Participant shall be
entitled to receive only a Reduced Retirement Benefit (determined as hereinafter
provided) commencing at his or her date of retirement. "Reduced Retirement
Benefit" shall mean the amount equal to that percentage of the Participant's
Normal Retirement Benefit determined by subtracting from one hundred percent
(100%) the aggregate of 6.67% for each year (prorated over any partial year
based on completed months of service) between the Participant's retirement date
and the date on which the Participant would reach age sixty (60). If a
Participant retires prior to age sixty (60) but does not begin receiving
benefits under this Plan until he or she is at least age sixty (60), there shall
be no reduction in the Participant's Normal Retirement Benefit. For purposes of
determining the amount of the Normal Retirement Benefit or the Reduced
Retirement Benefit, as the case may be, for a Participant who retires after
August 1, 1996, and prior to age sixty-five (65), each of the offset amounts
under paragraphs (i), (ii) and (iii) of Section 4.1(b) shall be calculated by:
(i) determining the value of the projected amount such Participant would receive
if he or she began receiving the benefits described in such paragraphs beginning
on the earliest date such benefits become payable and (ii) converting this
amount to an actuarially equivalent (determined in accordance with Section 5.3)
single life annuity beginning on the date such Participant begins receiving
benefits under this Plan.

          (b) If a Participant retires prior to his or her Early Retirement
Date, the Participant shall be entitled to receive any of his or her  Normal
Retirement Benefit which is then Vested.  Such Normal Retirement Benefit shall
be payable, at the election of the Participant pursuant to Section 4.3 (or, if
the Participant has not made an election, at the election of the Committee), as
follows:  (1) beginning at the time the Participant becomes age fifty-five (55)
(or at Participant's current age if he is age fifty-five (55) or older), with a
Reduced Retirement Benefit determined as provided in subparagraph (a) above, or
(2) beginning at the time the Participant becomes age sixty (60), with no
reduction in the Normal Retirement Benefit, or (3) if Participant is under
fifty-five (55) years of age when he or she retires, as a single lump sum
payment at the time of retirement equal to the present value of his or her
Normal Retirement Benefit, determined using the actuarial equivalent, as defined
in Section 5.3.

     4.3  Elections Related to Early Retirement.
          ------------------------------------- 

          For a Participant retiring after his Early Retirement Date but prior
to his Normal Retirement Date pursuant to Section 4.2(a), he may elect, by a
written election delivered to the Corporate Secretary of the Company at least
thirty (30) days prior to his retirement, whether he wishes to receive: (1) a
Reduced Retirement Benefit which will begin being paid immediately pursuant to
the payment terms of Article V (not applicable if Participant is age sixty (60)
or older), or (2) a Normal Retirement Benefit that will not begin being paid
until age sixty (60) (or his current age if he is age sixty (60) or older). For
a Participant retiring prior to his Early Retirement Date pursuant to Section
4.2(b), he may elect, by a written election delivered to the Corporate Secretary
of the Company at least thirty (30) days prior to his retirement, whether he

                                       6
<PAGE>
 
wishes to receive:  (1) a Reduced Retirement Benefit which will become payable,
per the payment terms of Article V, at age fifty-five (55) (or his current age
if he is age fifty-five (55) or older), or (2) a Normal Retirement Benefit which
will become payable, per the payment terms of Article V, at age sixty (60), or
(3) if a Participant is under age fifty-five (55), the actuarial equivalent,
determined in accordance with Section 5.3, of his Normal Retirement Benefit,
paid as a lump sum payment.  For each Participant electing either option (1) or
option (2) above, such Participant may elect an optional form of payment under
the terms of Section 5.4.

     5.1  Normal Form of Payment.
          ---------------------- 

          Unless an optional form of payment is elected by the Participant in
accordance with Section 5.4 (or by the Committee in accordance with Section 4.2
or Section 5.2 hereof), all retirement benefits payable pursuant to this Plan
will be paid in the form of a single life annuity, payable monthly, for the life
of the Participant.  Except as otherwise provided in this Plan, the first
monthly payment shall be made on the first day of the calendar month following
the Participant's retirement date.

     5.2  Other Forms of Payment.
          ---------------------- 

          Each Participant may elect, pursuant to Section 5.4, to receive
payment of his retirement benefits via one of the following optional forms of
payment, rather than via the form of payment described in Section 5.1:

          (a) A one hundred percent (100%) joint and survivor annuity, pursuant
to which an annuity is payable for the life of the Participant with a survivor's
annuity for the life of the Participant's spouse, which annuity is equal to one
hundred percent (100%) of the amount of the annuity payable during the joint
lives of the  Participant and his or her spouse.

          (b) A fifty percent (50%) joint and survivor annuity, pursuant to
which an annuity is payable for the life of the  Participant with a survivor's
annuity for the life of the  Participant's spouse, which annuity is equal to
fifty percent (50%) of the amount of the annuity payable during the joint lives
of the  Participant and his or her spouse.

          (c) A ten (10) year certain installment payment, pursuant to which a
fixed monthly benefit is payable to the Participant for the lesser of ten (10)
years or the life of the  Participant, with the continuation of the same benefit
to the Participant's designated beneficiary for any remaining portion of the ten
(10) year certain period if the Participant dies prior to the end of such
period.

                                       7
<PAGE>
 
          (d) A five (5) year certain installment payment, pursuant to which a
fixed monthly benefit is payable to the  Participant for the lesser of five (5)
years or the life of the  Participant, with the continuation of the same benefit
to the Participant's designated beneficiary for any remaining portion of the
five (5) year certain period if the Participant dies prior to the end of such
period.

          (e) A single lump sum payment.

          If a Participant does not make a timely election to receive payment of
his retirement benefits via one of the optional forms of payment described in
Subsections (a) through (e) above, the Committee may elect one of the above-
described optional forms of payment for such Participant, but only with his
written consent.

     5.3  Actuarial Equivalent.
          -------------------- 

          Any optional form of payment described in Section 5.2 shall be the
actuarial equivalent of the normal form of payment specified in Section 5.1
hereof.  All determinations of actuarial equivalency will be based on the 1983
Unloaded Group Annuity Mortality Table weighted fifty percent (50%) male and an
interest rate of eight percent (8.0%).  The lump sum amount will equal the
present value of future payments under this Plan, assuming payment of benefits
commenced immediately (or age fifty-five (55) for a Vested termination on or
before the Participant's 55th birthday).

     5.4  Election of Form of Payment.
          ----------------------------

          If a Participant does not make a written election to the contrary at
least thirty (30) days prior to his retirement, such Participant's retirement
benefits under this Plan shall be payable in the form of a single life annuity,
paid pursuant to the terms of Section 5.1, unless the Committee (with the
consent of such Participant) elects to pay the retirement benefits pursuant to
one of the other forms of payment set forth in Section 5.2. If a Participant
makes a written election at least thirty (30) days prior to his retirement, he
may elect one of the forms of payment described in Sections 5.2(a) through
5.2(e), and the Committee must comply with such payment election. Participant
may modify his election at any time by making another written election, provided
such written election is received by the Company's Corporate Secretary at least
thirty (30) days prior to his retirement. For a written election to be validly
made, Participant must deliver such a written election to the Corporate
Secretary of the Company and such election shall be deemed made on the date on
which the Corporate Secretary receives it.

payment of retirement benefits, the Participant shall be deemed to have retired
for purposes of this Plan on the later of (i) the day immediately preceding his
or her death, or (ii) the first day of the first calendar month thereafter in
which the Participant would have attained age fifty-five (55), and the
Participant's surviving spouse, if any, shall be entitled to a benefit equal to

benefit shall be payable in the form of a single life annuity for the life of
the surviving spouse.

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

          (c) 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 eight
percent (80%) of the combined voting power of the outstanding 

                                       10

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.

          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 acquisition, by reducing the number of Voting Securities outstanding,
increases the proportional number of shares Beneficially Owned by the Subject
Person, provided that if, after a Change in Control would occur (but for the
        --------                                                            
operation of this sentence) as a result of such 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.

          grant of 20,000 shares upon approval by the Board of this Plan or upon
          his or her initial appointment or election to the Board.


     (c)  Automatic Grants.  An Option to purchase 5,000 shares of Common Stock
          ----------------                                                     
          shall be granted at the annual meeting of the Board held on the date
          of the Annual Meeting of Shareholders beginning in 1995 and at each
          succeeding Board meeting held on that date, provided the Non-Employee
          Director continues in office after the Board meeting date on which the
          Option is granted.

     (d)  Option Agreement.  Each Option shall be evidenced by a written
          ----------------                                              
          instrument which shall state the terms and conditions of the grant,
          not inconsistent with the Plan, as the Board in its sole discretion
          shall determine and approve.

     (e)  Option Price.  The purchase price for each share of Common Stock
          ------------                                                    
          subject to an Option shall be the fair market value of the Common
          Stock on the date the Option is granted.  For this purpose, as well as
          other purposes under the Plan, fair market value shall be deemed to be
          the closing selling price of a share of Common Stock as reported on
          the New York Stock Exchange Composite on the date on which the Option
          is granted or, if there is no trade on such Exchange on that date,
          then on the next preceding date on which there was a trade of Common
          Stock on such Exchange.  (In the event the Company's Common Stock is
          not listed on the New York Stock Exchange on the date of 

                                       1
<PAGE>
 
          an Option grant, the fair market value shall be determined as stated
          above but with reference to trades on the largest stock exchange on
          which the Common Stock is then traded.)

     (f)  Nontransferability.  An Option shall be nonassignable and
          ------------------                                       
          nontransferable other than by will or the laws of descent and
          distribution.  An Option shall be exercisable during the Eligible
          Director's lifetime only by him or, in the event of his incompetence,
          by a duly appointed guardian.

5.   OPTION EXERCISES.

     (a)  Exercise Timing.  Except as provided in Sections 5(c) and 6 below,
          ---------------                                                   
          each Option shall become exercisable for twenty-five percent (25%) of
          the shares of Common Stock covered by the Option after the expiration
          of one (1) year following the date of grant and for an additional
          twenty-five percent (25%) of the shares after the expiration of each
          of the succeeding three (3) years following the date of grant.

     (b)  Method of Exercise.  Options may be exercised by delivery of written
          ------------------                                                  
          notice of exercise to the Secretary of the Company, accompanied by the
          full purchase price of the shares being purchased.  The price shall be
          paid at the time of exercise (i) in cash, (ii) by the transfer to the
          Company of shares of the Company's Common Stock acquired by the option
          holder prior to the exercise of the Option, or (iii) by any
          combination of cash or such shares of the Company's Common Stock.
          Each such share so transferred in full or part payment of the option
          price shall be deemed to have a value equal to the closing price of a
          share of the Common Stock of the Company, as traded on the New York
          Stock Exchange (or the largest stock exchange on which it is then
          traded), on the date of transfer to the Company, or if there is no
          trade on such Exchange on that date, on the nearest date preceding the
          date of transfer on which a trade on such Exchange was made, and each
          such share at the time of such transfer shall be free and clear of any
          and all claims, pledges, liens and encumbrances, or any restrictions
          which would in any manner restrict the transfer of such shares to the
          Company in full or part payment of the Option price.

     (c)  Effect of Change of Control.  In the event of "Change of Control" of
          ---------------------------                                         
          the Company, all Options held by Eligible Directors on the date of
          Change of Control shall be immediately exercisable in full,
          irrespective of the amount of time that has elapsed from the date of
          grant.  "Change  of Control" means a change of twenty-five percent
          (25%) or more of the membership of the Board (excluding membership
          changes resulting from normal retirement of directors) within a
          twenty-four (24) month period following the acquisition of beneficial
          ownership by any person or entity, or group of persons or entities and
          their affiliates acting in concert, of twenty percent (20%) or more of
          the voting securities of the Company.  "Affiliates" and "beneficial
          ownership" shall be defined in accordance with Rules 12b-2 and 13d-3
          of the Securities and Exchange Commission, as the same may from time
          to time be amended.

6.   EXPIRATION OF OPTIONS.   Except as hereinafter provided, all Options shall
     expire on the earlier of (i) the last day of the tenth (10th) year after
     the date of grant or (ii) the date that an Eligible Director ceases to be a
     member of the Board; provided, however, that to the extent any unexpired
     Options are otherwise exercisable on the date that an Eligible Director
     ceases to be a member of the Board for any reason other than Cause (as
     defined below), death, Early 

                                       2
<PAGE>
 
     Retirement (as defined below) or Mandatory Retirement (as defined below),
     such Options shall remain exercisable for one (1) year following the last
     day of the Eligible Director's Board membership and shall expire if not
     exercised within said one (1) year period. If Board membership ceases on
     account of death or Mandatory Retirement, all unexpired Options held by the
     Eligible Director on the last day of Board membership, whether exercisable
     or not exercisable, shall be immediately exercisable and remain exercisable
     for three (3) years following the last day of the Eligible Director's Board
     membership and shall expire at the end of such three (3) year period if not
     exercised within said three (3) year period. If Board membership ceases on
     account of Early Retirement, all unexpired Options held by the Eligible
     Director on the last day of Board membership, which are then exercisable or
     would have become exercisable had the Director continued as a member of the
     Board for one (1) additional year, whether exercisable or not exercisable,
     shall be immediately exercisable and remain exercisable for one (1) year
     following the last day of the Eligible Director's Board membership and
     shall expire if not exercised within said one (1) year period. To the
     extent any otherwise unexpired Options are not exercisable in accordance
     with the immediately preceding sentence, they shall expire as of the
     effective date of such Eligible Director's Early Retirement. All Options
     held by an Eligible Director whose membership on the Board ends after the
     occurrence of Cause shall expire immediately on his or her last day of
     Board membership. "Cause," for the purposes of this Section 6, means any
     act or omission for which indemnification of the Director is prohibited by
     the Georgia Business Corporation Code (Sections 14-2-171 of the Code until
     July 1, 1989 and Section 14-2-856, as amended, on and after July 1, 1989).
     "Mandatory Retirement," for the purposes of this Section 6, means an
     Eligible Director's ineligibility to be re-elected to the Board due to the
     terms of the retirement policy adopted by the Board (as amended from time
     to time), provided such ineligibility occurs after at least thirty-six (36)
     consecutive months of service on the Board. "Early Retirement," for the
     purposes of this Section 6, means an Eligible Director's voluntary
     resignation from the Board after at least thirty-six (36) consecutive
     months of service on the Board.

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 or shares of Common Stock of the Company occurs, the
     number and kind of shares authorized by this Plan, and the number, Option
     price and kind of shares covered by the Options granted hereunder, shall be
     automatically adjusted as required in order to prevent an unfavorable
     effect upon the value of the shares covered by then outstanding Options and
     shares covered by Options subsequently granted.

8.   TAX WITHHOLDING.    Any exercise of an Option pursuant to the Plan shall be
     subject to withholding of state and federal income taxes, FICA tax or other
     taxes to the extent required by applicable law.

9.   LAWS AND REGULATIONS.   The Plan, the grant and exercise of Options, and
     the obligation of the Company to sell or deliver shares of Common Stock
     under the Plan shall be subject to all applicable laws, regulations and
     rules.  In the event that the shares of Common Stock to be issued under
     this Plan are not registered under the Securities Act of 1933 and any
     applicable state securities laws prior to the delivery of such shares, the
     Company may require, as a condition to the issuance thereof, that the
     persons 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 own account and not with a view to, for resale in
     connection with, or with an intent of participating directly or indirectly
     in, any distribution of such shares within the 

                                       3
<PAGE>
 
     meaning of that Act, and a legend to that effect may be placed on the
     certificates representing such shares.

10.  TERMINATION AND AMENDMENT OF THE PLAN.   The Board may at any time
     terminate the Plan or may at any time or times amend the Plan or amend any
     outstanding Options 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:

     (i)  no amendment of any outstanding Option shall contain terms or
          conditions inconsistent with the provisions contained in the Plan at
          the time the respective Option was granted, as determined by the
          Board; and

     (ii) except as provided in Section 7, no such amendment shall, without the
          approval of the shareholders of the Company:  (a) increase the number
          of shares of Common Stock for which each Option may be granted under
          the Plan; (b) increase the frequency of Option grants; (c) reduce the
          price at which Options may be granted or exercised below the price
          provided for in Section 4(e); (d) extend the period during which any
          outstanding Option may be exercised; (e) materially increase in any
          other way the benefits accruing to Eligible Directors; (f) expand Plan
          eligibility beyond Eligible Directors as defined herein, or (g)
          disqualify an Eligible Director from being a "disinterested"
          administrator, within the meaning of Rule 16b-3 (or any successor
          rule) of the Securities and Exchange Commission, of any stock option
          plan or other stock-based plan of the Company.

11.  EFFECTIVE DATE.   The Plan shall become effective on the date of approval
     by the Board; provided, however, that the Plan shall be submitted to the
     shareholders of the Company for approval, and if not approved by the
     shareholders within one (1) year from the date of approval by the Board,
     the Plan shall be of no force and effect.  Options granted under the Plan
     before approval of the Plan by the shareholders shall be granted subject to
     such approval and shall not be exercisable before such approval.

To record the adoption of this Plan (as amended and restated) by the Board as of
May 12, 1999, the Company has caused its authorized officers to execute this
Plan in the space below.

                             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-Q
(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 and the Latin America 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 and / or deployment 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 as both competitors and customers; 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"); Year 2000
Problems that may exist in products currently or historically sold to customers
of the company; and delays in providing upgrades to customers to prevent Year
2000 problems in products sold by 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.
