                                    FORM OF
                               FIRST AMENDMENT TO
            FISCAL YEAR 1997 MANAGEMENT INCENTIVE PLAN (THE "PLAN")
               FOR EXIDE ELECTRONICS GROUP, INC. (THE "COMPANY")
 
     The Plan is hereby amended, effective as of July   , 1997, as set forth
below, pursuant to the authority of the HRC to amend the Plan as set forth in
the Plan. (All capitalized terms used in this First Amendment and not defined
herein shall have the meanings ascribed to them in the Plan.)
 
     1.  If a Change of Control occurs on or before September 30, 1997, the Plan
Period shall be deemed to have ended immediately before the Change of Control,
the Board shall determine MIP Payments in accordance with the Plan but based
upon performance only during the Plan Period as so ended, and MIP Payments shall
be made as soon as possible and practicable following the Change of Control and
in no event later than 90 days thereafter.
 
     2.  In addition, if a Change of Control occurs at any time after the date
of this Amendment pursuant to an agreement entered into by the Company, which
agreement is authorized by the Board on or before September 30, 1998, then each
Participant shall be entitled to receive a supplemental cash bonus (the
"Supplemental Bonus"), computed and payable as set forth below, and subject to
the conditions set forth below.
 
     3.  The Supplemental Bonus for each Special Participant shall be the
Special MIP Amount set forth opposite such Special Participant's name on
Schedule C hereto. The Supplemental Bonus for each Plan Participant shall equal
the excess (if any) of the Special MIP Amount for such Plan Participant over the
MIP Payment that becomes payable to such Plan Participant (i) pursuant to the
Plan without regard to this Amendment, if a Change of Control does not occur on
or before September 30, 1997, or (ii) pursuant to Section 1 above, if a Change
of Control does occur on or before September 30, 1997. (The amount described in
clauses (i) or (ii) of the preceding sentence, as applicable, is hereafter
referred to as the "Regular MIP Amount.") If the Special MIP Amount for a Plan
Participant does not exceed the Regular MIP Amount, then notwithstanding any
other provision of this Amendment, no Supplemental Bonus shall be payable to
such Plan Participant. If the Regular MIP Amount for a Plan Participant is zero,
then the Supplemental Bonus for such Plan Participant shall equal his or her
Special MIP Amount.
 
     4.  Any Supplemental Bonus that becomes payable to a Participant as
provided above shall be paid in two installments. The first such installment
(the "First Installment") shall equal one-half of the Special MIP Amount, and
shall be paid as soon as possible and practicable after the Change of Control
and in any event not later than the 15th day after the Change of Control. The
second such installment (the "Second Installment") shall equal one-half of the
Supplemental Bonus and shall be paid on the 180th day after the Change of
Control; provided, that in the case of Plan Participants, the amount of the
Second Installment shall be reduced (but not below zero) by the Regular MIP
Amount.
 
     5.  Notwithstanding any other provision of this Amendment, neither
installment of a Supplemental Bonus shall be paid to any Participant who has not
been an employee of the Company for the entire Required Period for such
installment. The "Required Period" for each installment of a Supplemental Bonus
shall be the period beginning on (a) the first day of the Plan Period or such
later date during the Plan Period as the Plan Participant first became a Plan
Participant pursuant to the terms of the Plan or, in the case of a Special
Participant, on the date of this Amendment and ending on (b) the earlier of (i)
in the case of the First Installment, the day before the date of the Change of
Control, and in the case of the Second Installment, the 180th day after the date
of the Change of Control, and (ii) the date there occurs any Wrongful
Termination of the Participant's employment.
 
     6.  The following new definitions are added to the Plan:
 
          "Aggregate Change of Control Equity Value" means the Change of Control
     Price times the number of outstanding shares of voting stock of the Company
     as of the effective date of this Amendment,
   2
 
     appropriately adjusted through the date of the Change of Control to account
     for stock splits or combinations, stock dividends and similar adjustments
     to capitalization (other than exercises of stock options and warrants
     issued by the Company as of or before the effective date of this
     Amendment).
 
          "Cause" for termination of a Participant's employment shall be
     considered to exist if the termination of employment shall have taken place
     as a result of an act or acts of dishonesty by such Participant which
     constitutes a felony under the laws of the State of North Carolina and
     results in gain or personal enrichment of the Participant at the expense of
     the Company.
 
          "Change of Control" means:
 
             (a) the acquisition by any individual, entity or group (within the
        meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act
        of 1934, as amended (the "Exchange Act")) (a "Person") of beneficial
        ownership (within the meaning of Rule 13d-3 promulgated under the
        Exchange Act) of voting securities of the Company where such acquisition
        causes such Person to own 30% or more of the combined voting power of
        the then outstanding voting securities of the Company entitled to vote
        generally in the election of directors (the "Outstanding Company Voting
        Securities"); provided, however, that for purposes of this subsection
        (a), the following acquisitions shall not be deemed to result in a
        Change of Control: (i) any acquisition directly from the Company, (ii)
        any acquisition by the Corporation, (iii) any acquisition by any
        employee benefit plan (or related trust) sponsored or maintained by the
        Company or any corporation controlled by the Company or (iv) any
        acquisition pursuant to a transaction that complies with clauses (i),
        (ii) and (iii) of subsection (c) below; or
 
             (b) individuals who, as of the date hereof, constitute the Board of
        Directors (the "Incumbent Board") cease for any reason to constitute at
        least a majority of the Board of Directors; provided, however, that any
        individual becoming a director subsequent to the date hereof whose
        election, or nomination for election by the Company's shareholders, was
        approved by a vote of at least a majority of the directors then
        comprising the Incumbent Board shall be considered as though such
        individual were a member of the Incumbent Board, but excluding, for this
        purpose, any such individual whose initial assumption of office occurs
        as a result of an actual or threatened election contest with respect to
        the election or removal of directors or other actual or threatened
        solicitation of proxies or consents by or on behalf of a Person other
        than the Board of Directors; or
 
             (c) the approval by the shareholders of the Company of a
        reorganization, merger or consolidation or sale or other disposition of
        all or substantially all of the assets of the Company or the acquisition
        of assets of another entity ("Business Combination") or, if consummation
        of such Business Combination is subject, at the time of such approval by
        shareholders, to the consent of any government or governmental agency,
        the obtaining of such consent (either explicitly or implicitly by
        consummation); excluding, however, such a Business Combination pursuant
        to which (i) all or substantially all of the individuals and entities
        who were the beneficial owners of the Outstanding Company Voting
        Securities immediately prior to such Business Combination beneficially
        own, directly or indirectly, more than 60% of, respectively, the then
        outstanding shares of common stock and the combined voting power of the
        then outstanding voting securities entitled to vote generally in the
        election of directors, as the case may be, of the corporation resulting
        from such Business Combination (including, without limitation, a
        corporation that as a result of such transaction owns the Company or all
        or substantially all of the Company's assets either directly or through
        one or more subsidiaries) in substantially the same proportions as their
        ownership, immediately prior to such Business Combination of the
        Outstanding Company Voting Securities, (ii) no Person (excluding any
        employee benefit plan (or related trust) of the Company or such
        corporation resulting from such Business Combination) beneficially owns,
        directly or indirectly, 30% or more of, respectively, the then
        outstanding shares of common stock of the corporation resulting from
        such Business Combination or the combined voting power of the then
        outstanding voting securities of such corporation except to the extent
        that such ownership existed prior to the Business Combination and (iii)
        at least a majority of the members of the board of directors of the
        corporation resulting
 
                                        2
   3
 
        from such Business Combination were members of the Incumbent Board at
        the time of the execution of the initial agreement, or of the action of
        the Board of Directors, providing for such Business Combination; or
 
             (d) approval by the shareholders of the Company of a complete
        liquidation or dissolution of the Company.
 
          "Change of Control Price" means the higher of (i) the highest reported
     sales price, regular way, of a share of common stock of the Company in any
     transaction reported on the New York Stock Exchange Composite Tape or other
     national exchange on which such shares are listed or on NASDAQ during the
     60-day period prior to and including the date of a Change of Control or
     (ii) if the Change of Control is the result of a tender or exchange offer
     or a Business Combination, the highest price per share of Common Stock paid
     in such tender or exchange offer or Business Combination. To the extent
     that the consideration paid in any such transaction described above
     consists all or in part of securities or other noncash consideration, the
     value of such securities or other noncash consideration shall be determined
     based upon trading on a national exchange or NASDAQ, if any, and otherwise,
     by the Board.
 
          "Good Reason" means:
 
             (a) the Participant's base salary is reduced below the higher of
        (i) the Participant's base salary as in effect immediately before the

        the request of a third party who has taken steps reasonably calculated
        to effect a Change of Control or otherwise arises in connection with or
        anticipation of a Change of Control) and (ii) the Participant's highest
        base salary in effect at any time thereafter;
 
             (b) without the Participant's express written consent, the
        Participant is assigned any duties inconsistent in any respect with the
        Participant's position (including status, offices, titles and reporting
        requirements), authority, duties or responsibilities as in effect before
        the Change of Control, or the Company takes any other action which
        results in a diminution in such position, authority, duties or
        responsibilities as compared to before the Change of Control, excluding
        for this purpose an isolated, insubstantial and inadvertent action not
        taken in bad faith and which is remedied by the Company promptly after
        receipt of notice thereof given by the Participant;
 
             (c) without the Participant's express written consent, the Company
        requires the Participant to change the location of his or her job or
        office, so that he or she will be based at a location more than fifty
        (50) miles from the location of his job or office immediately prior to
        the Change of Control;
 
             (d) the Company fails to continue in effect, or, in the case of a

        similar benefit or plan, any benefit or compensation plan, profit
        sharing plan, 401(k) plan, stock purchase plan, stock option plan, life
        insurance plan, or health, accident or disability plan in which the
        Participant is participating before the Change of Control (or plans
        providing no less favorable and substantially similar benefits), or the
        Employer takes any action which would materially adversely affect the
        Participant's participation or materially reduce the Participant's
        benefits under any of such plans;
 
             (e) the Company takes any action which would deprive the
        Participant of any material fringe benefit to which he or she was
        entitled immediately prior to the Change of Control;
 
             (f) a successor company fails or refuses to assume the Company's
        obligation under the Plan;
 
             (g) the Company or any successor company breaches any of the

        severance agreement with the Company, the material breach by the
        Employer of any provision of such employment agreement.
