                                    FORM OF
                          AMENDMENT TO PROMISSORY NOTE
 
     The Promissory Note (the "Note") dated             , 199 whereby [NAME OF
EXECUTIVE] (the "Obligor") has promised to pay to the order of Exide Electronics
Group, Inc. the principal sum of $     , on terms and conditions more fully set
forth in the Note, is hereby amended, effective as of July   , 1997, as set
forth below. (All capitalized terms used in this Amendment and not defined
herein shall have the meanings ascribed to them in the Note.)
 
     1.  Notwithstanding any other provision of the Note, if at the time the
Note would otherwise become payable pursuant to its terms, the Obligor is
unable, by reason of any applicable law, regulation or agreement with the
Company, to dispose of any Shares acquired with the proceeds of such Note in an
orderly fashion, or if disposition of any such Shares by the Obligor would, in
the view of the Company's independent accountants, jeopardize the intended
accounting treatment of any transaction to which the Company is a party, the
Note shall not become payable until such time as there has occurred a period of
not less than 75 consecutive business days during which (a) the Obligor has not
been so unable to sell the Shares and (b) such disposition would not, in the
view of the Company's independent public accountants, jeopardize such accounting
treatment.
 
     2.  Notwithstanding the foregoing, the amendment made by this Amendment to
the Note shall not be effective in connection with a corporate transaction that
the Corporation intends to be eligible for pooling-of-interests accounting under
APB No. 16 if and to the extent that giving effect to such amendment would make
such transaction ineligible for such accounting treatment.
 
     3.  The Note is in all other respects ratified and affirmed without
amendment.
