                               ANTEC CORPORATION
                           2000 STOCK INCENTIVE PLAN

         1. PURPOSE AND EFFECTIVE DATE. ANTEC Corporation (the "Company") has
established this 2000 Stock Incentive Plan (the "Plan") to facilitate the
retention and continued motivation of key employees, consultants and directors
and to align more closely their interests with those of the Company and its
stockholders. The effective date of the Plan shall be March 1, 2000 subject to
the approval of the Company's shareholders at the 2000 Annual Meeting.

         2. ADMINISTRATION. The Plan shall be administered by the Board of
Directors, or the Compensation Committee of the Company's Board of Directors or
such other Board committee as the Board may designate (the "Committee"). The
Committee has the authority and responsibility for the interpretation,
administration and application of the provisions of the Plan, and the
Committee's interpretations of the Plan, and all actions taken by it and
determinations made by it shall be binding on all persons. No Board or
Committee member shall be liable for any determination, decision or action made
in good faith with respect to the Plan.

         3. SHARES SUBJECT TO PLAN. A total of 2,500,000 shares of Common Stock
of the Company ("Shares"), par value $.01 per share may be issued pursuant to
the Plan. The Shares may be authorized but unissued Shares or Shares reacquired
by the Company and held in its treasury. Grants of incentive awards under the
Plan will reduce the number of Shares available thereunder by the maximum
number of Shares obtainable under such grants. If all or any portion of the
Shares otherwise subject to any grant under the Plan are not delivered for any
reason including, but not limited to, the cancellation, expiration or
termination of any option right or unit, the settlement of any award in cash,
the forfeiture of any restricted stock, or the repurchase of any Shares by the
Company from a participant for the cost of the participant's investment in the
Shares, such number of Shares shall be available again for issuance under the
Plan. The number of Shares covered by or specified in the Plan and the number
of Shares and the purchase price for Shares under any outstanding awards, may
be adjusted proportionately by the Committee for any increase or decrease in
the number of issued Shares or any change in the value of the Shares resulting
from a subdivision or consolidation of Shares, reorganization,
recapitalization, spin-off, payment of stock dividends on the Shares, any other
increase or decrease in the number of issued Shares made without receipt of
consideration by the Company, or the payment of an extraordinary cash dividend.

         4. ELIGIBILITY. All key employees, active consultants and directors of
the Company and its subsidiaries are eligible to be selected to receive a grant
under the Plan by the Committee. The Committee may condition eligibility under
the Plan or participation under the Plan, and any grant or exercise of an
incentive award under the Plan on such conditions, limitations or restrictions
as the Committee determines to be appropriate for any reason. No person may be
granted in any period of two consecutive calendar years, awards covering more
than 1,000,000 Shares.

         5. AWARDS. The Committee may grant awards under the Plan to eligible
persons in the form of stock options (including incentive stock options within
the meaning of section 422 of the Code), stock grants, stock units, restricted
stock, stock appreciation rights, performance shares and units and dividend
equivalent rights, and reload options to purchase additional Shares if Shares
are delivered in payment of any other options, and shall establish the number
of Shares subject to each such grant and the terms thereof, including any
adjustments for reorganizations and dividends, subject to the following:

                  (a) All awards granted under the Plan shall be evidenced by
                  agreements in such form and containing such terms and
                  conditions not inconsistent with the Plan as the Committee
                  shall prescribe.

                  (b) The exercise price of any option or stock appreciation
                  right shall not be less than 85% of the fair market value of
                  a corresponding number of Shares as of the date of grant,
<PAGE>   2

                  except that such minimum option price may be reduced (but not
                  below par value) in the case of options granted in
                  consideration of a reduction in compensation by the amount of
                  such reduction.

                  (c) No more than 20% of the Shares may be awarded in a form
                  other than options or stock appreciation rights unless such
                  Shares are in payment of compensation earned or due at the
                  time of the award or within one year thereof.

                  (d) No option may be repriced by amendment, substitution or
                  cancellation and regrant, unless authorized by the
                  stockholders. Adjustments pursuant to Section 3 above shall
                  not be considered repricing.

         6. AMENDMENT OF THE PLAN. The Board of Directors or the Committee may
from time to time suspend, terminate, revise or amend the Plan or the terms of
any grant in any respect whatsoever, provided that, without the approval of the
stockholders of the Company, no such revision or amendment may increase the
number of Shares subject to the Plan, change the provisions of Section 5 above,
or expand those eligible for grants under the Plan.<PAGE>   1

                               ANTEC CORPORATION
                           MANAGEMENT INCENTIVE PLAN

         1. PURPOSE AND EFFECTIVE DATE. ANTEC Corporation (the "Company") has
established this Management Incentive Plan (the "Plan") to provide awards to
the executives of the Company for the achievement of goals of the Company for a
year or a specified number of years. The effective date of the Plan shall be
January 1, 2000 subject to the approval of the Company's shareholders at the
2000 Annual Meeting.

         2. ADMINISTRATION. The Plan shall be administered by the Board of
Directors, or the Compensation Committee of the Company's Board of Directors or
such other Board committee as the Board may designate (the "Committee"). The
Committee has the authority and responsibility for the interpretation,
administration and application of the provisions of the Plan, and the
Committee's interpretations of the Plan, and all actions taken by it and
determinations made by it shall be binding on all persons. No Board or
Committee member shall be liable for any determination, decision or action made
in good faith with respect to the Plan.

         3. AWARDS UNDER THE PLAN. The Committee shall assign a target
expressed as a percentage of salary each year. The targets may be as high as
200% and as low as 20% of salary.

         At least 51% of the target shall be dependent on the achievement of
financial objectives such as (i) operating, pretax, or net earnings of the
Company, a subsidiary, a business unit thereof, or an other entity where there
is a significant investment by the Company and opportunity to influence the
performance of that entity; (ii) earnings per share of the Company; (iii) cash
flow of any of these entities; (iv) return on capital, tangible or total,
employed by any of these entities as measured by any of these earnings; (v)
achievement of specified revenues or proceeds from specified activities, in or
out of the ordinary course of business; or (vi) other similar financial
objectives that the Committee determines to be in the interest of the Company.
Up to 49% of the target of a participant may be dependent on the subjective
determination of the Committee (or in the case of participants other than the
Chief Executive Officer and the Chairman, of an executive officer) of the
achievement of qualitative goals. In the case of John Egan, his target shall be
dependent on goals that are in accordance with his employment agreement.

         The actual awards may range from zero to 200% of the assigned targets
depending on the achievement of the objectives established by the Committee (or
in the case of qualitative goals of participants, other than the Chief
Executive Officer or the Chairman, by an executive officer) during the first 90
days of the year.

         4. ELIGIBILITY. All executive officers of the Company and the other
executives of the Company and its subsidiaries, who report directly to the
Chief Executive Officer of the Company are eligible to be selected to receive
an award under the Plan by the Committee. The Committee may condition
eligibility under the Plan or participation under the Plan, and any award under
the Plan on such conditions, limitations or restrictions as the Committee
determines to be appropriate for any reason and consistent with the terms of
the Plan. No person may be awarded, for any one year, more than $2,000,000, as
this amount is adjusted for inflation in the Consumer Price Index after
December 31, 2000.

         5. PAYMENT OF AWARDS. Amounts earned under the Plan shall be
determined and be paid as soon as practical after the end of each year or if
based on multiple years, the end of the last year of that period. The
Committee, in establishing the targets and goals for a year, may determine that
all or a portion of an award payable under the Plan to certain participants
shall or may be paid in stock or phantom stock of the Company that may or may
not be restricted. The computation of the amount of stock may be based on the
average market price of the stock over a period, up to one year, selected by
the Committee, or based on a percentage, not to be less than 75%, of the market
price of the stock at the end of the year for which the award was earned or
during a period during the last month of that year selected by the Committee.

         6. AMENDMENT OF THE PLAN. The Committee may amend or terminate the
Plan at any time, provided however, that in no event can the Committee, after
the period for establishing the objectives for a year, adjust for that year any
targets, objectives, or the percentage of target earned by levels of
achievement of each objective in a manner that would increase the amount of
compensation that would be payable under the Plan without such adjustment.
