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

     The Employer shall cause to be established and maintained a separate
Deferred Benefit Account for each Compensation Deferral Election.  The Employer
shall credit the Election Amount (less any amount that the Employer may be
required from time to time to withhold pursuant to federal, state or local law)
deferred pursuant to each such Election Form to the Participant's appropriate
Deferred Benefit Account, and to the investment option selected by the
Participant pursuant to Section 5.4(d), as of the date deferred from
Participant's Compensation as provided in Section 4.1 hereof.

      ----
Savings Match Account (as defined below).

     5.3  Determination of Savings Match Account Balance
          ----------------------------------------------

     Beginning January 1, 2001, the Employer shall cause to be established and
maintained a separate Savings Match Account for each Participant who contributed
either (a) 6% of his Eligible Compensation for the preceding calendar year
(where such Eligible Compensation does not exceed $170,000, as adjusted by
401(a)(17)) or (b) $10,500 (as adjusted by 402(g)) of his Eligible Compensation
in the preceding calendar year, to the Scientific-Atlanta, Inc. Voluntary
Employee Retirement and Investment Plan (the "401(k) Plan").  On or before
January 31 of each calendar year, the Plan Committee shall credit to the
Participant's Savings Match Account an amount equal to the additional matching
contribution that would have been made under the 401(k) Plan had the amount(s)
of the Compensation Deferral Election(s) for the preceding calendar year been
contributed to the 401(k) Plan and the compensation or deferral limits under
Sections 401(a)(17) and 402(g) of the Code had not applied to the 401(k) Plan
(the "Savings Match"); provided, however, for calendar year 2000, only the
amounts deferred after July 1, 2000, shall be eligible for any Savings Match.
The Plan Committee shall credit the Savings Match to the investment options in
the same proportion as the Compensation Deferral Election(s)

                                       8
<PAGE>

that were made throughout the preceding calendar year, except that the Savings
Match attributable to the Insurance Fund for the Participant shall be placed in
the Fixed Income Fund for such Participant. The Plan Committee shall provide a
retroactive credit to the Savings Match Account in an amount equal to earnings
attributable to the Savings Match based on the investment options that the
Participant selected under the Plan.

     5.4  Investment Options
          ------------------

     (a)  Beginning July 1, 2000, subject to the limitations of Section 3.1, a
Participant may select one or more investment options listed in 5.4(d) for each
Compensation Deferral Election relating to Compensation deferred under the Plan
on or after July 1, 2000.  Any investment option selection must specify the
percentage of the amount specified in the Compensation Deferral Election to be
invested in each investment option in 1% increments.  All deferrals made to the
Plan prior to July 1, 2000 shall remain in the Fixed Income Fund, except that
Insurance Fund Participants may transfer all or a portion of the pre-July 1,
2000 Fixed Income Fund balance to the Insurance Fund at any time.

     (b)  Any investment option selection made by a Participant for the
investment of his Account shall be made in accordance with this section.  The
Participant shall make the initial investment option selection on a form
provided by the Plan Committee.  Thereafter the Participant may modify his
initial investment option selection for past amounts deferred and/or for future
deferrals by notifying the Plan Committee or its designated agent of the
modification in the manner permitted under the Plan Committee's guidelines.  A
Participant may modify his investment option selection during the ten-day period
commencing on July 1 of each year, except that Participants eligible to
participate in the Insurance Fund may modify their investment option from any
investment option to the Insurance Fund at any time.  Any investment option
modification shall be implemented as soon as administratively practicable
following the Plan Committee's receipt of a written investment option selection
modification.  An investment option selection for a Compensation Deferral
Election shall remain in effect until superseded by a subsequent investment
option selection modification, or until the complete distribution of the
Participant's Deferred Benefits related to that Compensation Deferral Election.

     (c)  If a Participant fails to submit an investment option selection for a
Compensation Deferral Election, or if a Participant's investment option
selection does not equal 100%, the portion of the Participant's Compensation
Deferral Election that is not subject to an investment option selection shall be
invested in the Fixed Income Fund.

     (d)  The investment options offered by the Plan are:

          (i)    Fixed Income Fund (defined in Section 2.13);
          (ii)   Insurance Fund (defined in Section 2.15); and
          (iii)  Such other investment options as are made available under the
                 Plan by the Plan Committee from time to time.

shall deem desirable, setting forth a summary of the Compensation Deferral
Elections made, the current balances of the Deferred Benefit Accounts maintained

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.  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

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

     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

     Deferred Benefit Account not according to the Participant's elections as

     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
     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

                                       11
<PAGE>

     (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 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
          ----------------

     Except for amounts deferred into a Insurance Fund, 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.

                                       12
<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 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
          -----

     Except for amounts deferred into a Insurance Fund, Deferred Benefits shall
be paid upon the death of a Participant, as follows:

     (a)  Upon the death of a Participant, the Employer shall pay the amounts in
each of the Participant's Deferred Benefit Accounts to the Beneficiary
designated by the Participant with respect to each Compensation Deferral
Election in each of his or her respective Election Forms, or, if the Participant
fails to so designate a Beneficiary, to his or her estate.

     (b)  If the Participant dies prior to his or her Employment Termination
Date, the Employer shall pay to each respective Beneficiary or to the
Participant's estate, as the case may be, the amounts in each of the
Participant's respective Deferred Benefit Accounts, in the same manner as for
the Participant who has been terminated involuntarily, as set forth in Section
6.2(a).

     (c)  If the Participant dies following his or her Employment Termination
Date but prior to his or her receiving the full payment of all Deferred Benefits
payable to him or her, the Employer shall pay to each of the respective
Beneficiaries or to the Participant's estate, as the case may be, the same
Deferred Benefit in the same manner as it otherwise would have paid to the
Participant as if the Participant had not died, unless the Participant has
specified in his or her Election Form a different manner of payment to a
Beneficiary.

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

     (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).

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

     7.1  Hardship Withdrawals.  A Participant may request a Hardship Withdrawal
          ---------------------
of all or a portion of his or her Deferred Benefits (excluding amounts deferred
into a Insurance Fund) 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

          (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.

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

     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 terminated.  Upon termination of the Plan, amounts credited
to the Deferred Benefit Accounts of each Participant shall earn interest at the
interest rate provided by the Fixed Income Fund 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.

     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

                                       15
<PAGE>

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.

     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.

time, provided, however, that any amendment that does not involve a material
change in the nature of the Plan or a material increase in the cost of the Plan
may be adopted in writing, without approval of the Board of Directors, by the
Plan Committee.

     10.2  Inurement
           ---------

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

     All payments made pursuant to this Plan shall be subject to the withholding

       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 Five Million (5,000,000).  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.
<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;

                (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
<PAGE>

                (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

                     (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
<PAGE>

                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 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
<PAGE>

                shares Beneficially Owned by the Subject Person, provided, that
                                                                 --------
                if a Change in Control would occur (but for the operation of
                this 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.

                     (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.
<PAGE>

            (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.
                     ----------

                     (a)  For Options granted prior to August 18, 1999, 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, such Option, granted
                prior to August 18, 1999, 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.

                     (b)  For Options granted on or after August 18, 1999, 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 the Shares which he or she could have purchased at the time
                of Retirement. Additionally, if the Committee does not determine
                otherwise with respect to any Option, the right to exercise such
                Option shall continue to vest for a period of three (3) years
                after the Optionee's Retirement. To the extent unexercised, if
                the Committee does not determine otherwise with respect to any
                Option, such Option, granted on or after August 18, 1999, shall
                expire three (3) 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
            (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) for a period
            of three (3) years after such Employee's death, with respect to all
            Shares covered by the Option, regardless of whether the Option was
            exercisable as to such Shares prior to the Optionee's death.
            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.
<PAGE>

                (3)  Disability. If the Committee does not determine otherwise
                     ----------
            with respect to any Option, 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 had accrued pursuant to the terms of the applicable Option
            Agreement and had not previously been exercised.

                (4)  Termination for Cause. If the Committee does not determine
                     ---------------------
            otherwise with respect to any Option, 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 the Committee does not determine
                     -------------
            otherwise with respect to any Option, 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.

            (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, 2005.

       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
<PAGE>

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.

       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.
            ----------------------
<PAGE>

       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 as amended and restated by the Board
on April 17, 2000, the Corporation has caused this Plan to be executed by its
authorized officers.
