                             ARTICLES OF AMENDMENT
                       TO THE ARTICLES OF INCORPORATION
                                      OF
                           ABLE TELCOM HOLDING CORP.
                  ------------------------------------------

                      Pursuant to Section 607.0602 of the
                       Florida Business Corporation Act
                  ------------------------------------------

      Pursuant to Section 607.0602 of the Florida Business  Corporation Act (the
"FBCA"),  Able  Telcom  Holding  Corp.  (the  "Corporation")  hereby  adopts the
following Amendment to its Articles of Incorporation (the "Amendment"):

      1.    The name of the Corporation is Able Telcom Holding Corp.

      2. The  Amendment set forth below was duly adopted on December 13, 1996 by
the Board of Directors  pursuant to a special  meeting,  duly called and held in
accordance with Section 607.0820 of the FBCA.

      3. This Amendment to the  Corporation's  Articles of  Incorporation  shall
amend Article III in its entirety as follows:

                                  Article III

      The number of shares of stock that this  Corporation is authorized to have
outstanding at any one time is:

      TWENTY-SIX MILLION  (26,000,000)  SHARES CONSISTING OF TWENTY-FIVE MILLION
      (25,000,000)  SHARES OF COMMON  STOCK HAVING A PAR VALUE OF ONE TENTH OF A
      CENT ($.001) AND ONE MILLION  (1,000,000)  SHARES OF PREFERRED  STOCK (ONE
      THOUSAND TWO HUNDRED (1,200) SHARES OF WHICH SHALL BE DESIGNATED "SERIES A
      CONVERTIBLE  PREFERRED  STOCK") HAVING A PAR VALUE OF TEN CENTS ($.10) PER
      SHARE.

      The Board of Directors of the Corporation, by resolution,  shall establish
the rights, privileges,  vote, liquidation preference,  series,  convertibility,
dividend (whether  cumulative or non-cumulative),  and redemption  provisions of
the  Preferred  Stock  (other than Series A  Convertible  Preferred  Stock,  the
rights,  privileges,  vote,  liquidation  preference,   series,  convertibility,
dividend (whether  cumulative or non-cumulative)  and redemption  provisions for
which are set forth below).

      The holders of the Preferred Stock shall be entitled to dividends  thereon
at the rate  established  by the Board of  Directors  (except for  dividends  on
Series A Convertible  Preferred  Stock,  the rate for which is set forth below).
All  remaining  profits  which the Board of Directors  may determine to apply in
payment of  dividends  shall be  distributed  among the holders of Common  Stock
exclusively, except as may otherwise be set forth below. Except as otherwise set
forth  below  with  respect  to  Series  A  Convertible  Preferred  Stock,  upon
dissolution,  whether  voluntary or involuntary,  the holders of Preferred Stock
shall first be entitled  to receive,  out of the net assets of the  Corporation,
the  liquidating  value  established by the Board of Directors,  of their shares
plus unpaid accumulated dividends and any other distributions  declared thereon,
without interest.

      A.  SERIES A CONVERTIBLE PREFERRED STOCK

      1.  Designation and Amount.  The shares of such series shall be designated
"Series  A  Convertible  Preferred  Stock"  (herein  referred  to as  "Series  A
Preferred Stock"), having a par value per share equal to $.10, and the number of
shares constituting such series shall be 1,200.

      2.    Dividend Provisions.

                                      1





            (a) Dividends  Payable.  Cumulative  dividends  ("Dividends") on the
Series  A  Preferred  Stock  shall  accrue  at an  annual  rate  of  5.0% of the
Liquidation  Preference  (as  defined  below) per share  (such  rate  subject to
ratable  adjustment  in the event of any stock  split or  combination  and to an
equitable adjustment in the event of a reclassification or other similar event),
subject to the  remaining  terms and  conditions of this  subsection.  Dividends
shall accrue, whether or not declared, on each share of Series A Preferred Stock
from  December  20, 1996 (the  "Purchase  Date")  through the date on which such
dividends  are paid and  shall be  payable  in cash or  through  a  dividend  of
additional  shares of Series A Preferred Stock (as more fully described  below),
at the Corporation's  option,  quarterly in arrears,  on each March 20, June 20,
September 20 and December 20 following  the date on which the shares of Series A
Preferred Stock are issued for so long as any shares of Series A Preferred Stock
shall be  outstanding.  Shares of Series A Preferred Stock to be issued as stock
dividends  shall  be  issued  at a price  per  share  equal  to the  Liquidation
Preference.

            (b) Cash Dividends. In case the Corporation at any time or from time
to time shall declare,  order,  pay or make a cash dividend on the  Nonpreferred
Stock (as defined below) of the  Corporation,  the Board of Directors  shall, at
the same time or times  declare,  order,  pay and make a cash  dividend  on each
share of Series A  Preferred  Stock in an  amount  equal to the  product  of the
amount  of such  dividend  declared,  ordered,  paid or  made on each  share  of
Nonpreferred  Stock,  multiplied  by the  number of shares of Common  Stock into
which a share of Series A Preferred  Stock is convertible on the record date for
such action.

            (c) Other Distributions. In case the Corporation at any time or from
time to time shall declare,  order, pay or make a dividend or other distribution
(including, without limitation, any distribution of other or additional stock or
other  securities or property or rights or warrants to subscribe for  securities
of the  Corporation or any of its  subsidiaries  by way of dividend or spin-off,
reclassification,  recapitalization  or similar corporate  rearrangement) on its
Nonpreferred  Stock,  other  than a  dividend  payable  in cash or shares of the
Corporation's Nonpreferred Stock, then the Board of Directors shall, at the same
time or times,  declare,  order pay and make a dividend or other distribution on
each share of Series A Preferred  Stock which is  equivalent to such dividend or
other distribution declared, ordered, paid or made on each share of Nonpreferred
Stock,  multiplied by the number of shares of Common Stock into which a share of
Series A Preferred  Stock is convertible on the record date for such action.  So
long as any shares of Series A Preferred Stock are outstanding,  the Corporation
shall not declare,  order,  pay or make any such dividend or other  distribution
unless it  likewise  declares,  orders,  pays or makes  such  dividend  or other
distribution on all shares of Nonpreferred Stock.

            (d) Limitation on Distributions.  No deposit,  payment,  dividend or
distribution  of any kind shall be made with respect to the  Nonpreferred  Stock
unless all  accumulations  of dividends  payable on the Series A Preferred Stock
shall  have been paid.  So long as any Series A  Preferred  Stock  shall  remain
outstanding,  no dividend  or other  distribution  (except in Junior  Shares (as
defined  below))  shall  be  paid  or  made  on the  Nonpreferred  Stock  of the
Corporation  (except in accordance with  subsections (b) and (c) of this Section
2) or on other Junior  Shares of the  Corporation  and no share of  Nonpreferred
Stock or other Junior  Shares  shall be  purchased or otherwise  acquired by the
Corporation or any subsidiary of the Corporation.

            Subject  to the  above  limitations,  dividends  may be  paid on the
Nonpreferred  Stock out of any funds legally available for such purpose when and
as declared by the Board of Directors,  provided that dividends are also paid on
the Series A Preferred Stock in accordance with this Section 2.

            (e)   Certain Definitions.

      As used in this Section 2 and  elsewhere in these  Articles of  Amendment,
unless the context otherwise requires:

                  (i) The term  "business  day"  shall mean any day on which the
New York Stock  Exchange and  commercial  banks in New York and Florida are open
for business.

                  (ii) The term  "Common  Stock"  shall  mean the  Corporation's
authorized  Common Stock,  $.001 par value, as constituted on the Purchase Date,
and any stock into which such Common Stock may thereafter be changed,  and shall
also include stock of the Corporation of any class, which is not preferred as to

                                      2





dividends or assets over any other class of stock of the  Corporation  issued to
the holders of shares of Common Stock upon any reclassification thereof.

                  (iii) The term  "Control  Transaction"  shall have the meaning
set forth in subsection 8(a)(ii) below.

                  (iv) The term "Junior  Shares"  shall mean any class or series
of stock junior to the Series A Preferred  Stock as to dividends or distribution
of assets upon liquidation or otherwise.

                  (v) The term  "Liquidation  Event" shall mean the liquidation,
dissolution or winding up of the Corporation, either voluntary or involuntary.

                  (vi)  The term "Nonpreferred Stock" shall mean the Common 
     Stock and shall also include  stock of the  Corporation  of any other class
that  has no  preference  as to  dividends  or  distributions  of  assets,  upon
liquidation or otherwise,  over any other class of stock of the  Corporation and
that is not subject to redemption.

      3.    Liquidation Preference.

            (a) In the event of any Liquidation  Event,  the holders of Series A
Preferred Stock shall be entitled to receive,  prior to and in preference of any
distribution  of any  of the  assets  of  this  Corporation  to the  holders  of
Nonpreferred Stock and other Junior Shares by reason of their ownership thereof,
an amount per share equal to the sum of (i) $6,000 for each outstanding share of
Series  A  Preferred  Stock  (the   "Liquidation   Preference")   and  (ii)  all
accumulations  of unpaid  dividends  and other  distributions  on each  share of
Series A Preferred Stock. If upon the occurrence of such Liquidation  Event, the
assets and funds thus  distributed  among the  holders of the Series A Preferred
Stock shall be  insufficient  to permit the payment to such  holders of the full
aforesaid  preferential  amounts,  then  the  entire  assets  and  funds  of the
Corporation  legally  available for  distribution  shall be distributed  ratably
among the holders of the Series A Preferred Stock in proportion to the amount of
such Series A Preferred Stock owned by each such holder.

            (b) After the  distribution  in subsection  3(a) has been paid,  the
remaining  assets of the Corporation  available for distribution to shareholders
shall be distributed among the holders of Junior Shares in accordance with their
respective  rights thereto and the holders of Series A Preferred Stock shall not
be entitled to any further  participation  in any  distribution of the assets of
the Corporation.

      4.  Conversion. The  holders of the Series A  Preferred  Stock  shall have
conversion rights as follows (the "Conversion Rights"):

            (a)   Optional Conversion.

                  (i)  Each  share  of  Series  A   Preferred   Stock  shall  be
convertible,  at the option of the holder  thereof,  at any time following April
30, 1997, at the office of the  Corporation or any transfer agent for the Series
A Preferred Stock,  into such number of fully paid and  nonassessable  shares of
Common Stock as is determined by dividing the  Liquidation  Preference per share
by the lesser of the Fixed  Conversion  Price (as defined below) or the Floating
Conversion  Price (as defined  below) in effect at the time of  conversion.  The
lesser  of the Fixed  Conversion  Price or the  Floating  Conversion  Price,  as
applicable  at any given time,  is  hereinafter  referred to as the  "Conversion
Factor." The Conversion Factor for the Series A Preferred Stock shall be subject
to adjustment as set forth in this Section 4.

                  (ii) For purposes hereof, the following definitions shall 
apply:

                        (A)   The "Fixed Conversion Price" is $9.82.

                        (B) The "Floating  Conversion  Price" shall be 
determined  by  application  of  the  applicable   percentage  discount,  as set
forth below,  to the average closing bid price of a share of the Common Stock on
the Nasdaq National Market,  or other principal  securities  market on which its
Common Stock is traded,  for the three  trading days  immediately  preceding the

                                       3


date of the Conversion Notice (as defined below) or, in the case of a redemption
pursuant to Section 8 hereof,  the Redemption  Notice (as defined below) (or, if
the Common  Stock is not traded or listed on the Nasdaq  National  Market or any
other principal  securities  market, the average of the closing bid price in the
over-the-counter  market on such days as  reported  by Nasdaq or any  comparable
system, or if not so reported, as reported by any New York Stock Exchange member
firm selected by the  Corporation  for such purpose).  The  applicable  discount
shall be determined pursuant to the following table:

                                                   

           Conversion or
           Redemption Notice                             Percentage
           Received By:                         Discount

            May 20, 1997                                 10.0
            June 20, 1997                                12.5
            July 20, 1997                                12.5
            August 20, 1997                     15.0
            September 20, 1997                           15.0
            October 20, 1997                             17.5
            November 20, 1997                            17.5
            December 20, 1997 and thereafter    20.0


            (b) Upon any conversion of Series A Preferred  Stock,  payment shall
be made by the  Corporation  to each holder of the Series A  Preferred  Stock so
converted on account of dividends and other distributions  accrued but unpaid on
the Series A Preferred Stock.

            (c)  Mechanics  of  Conversion.  If the holder of shares of Series A
Preferred  Stock  desires  to  exercise  the right of  conversion  described  in
subsection  4(a), he shall give written notice to the Corporation (a "Conversion
Notice") of his or its election to convert a stated number of shares of Series A
Preferred Stock (the "Conversion Shares") into shares of Common Stock (provided,
however,  that the number of Conversion  Shares must in all events be sufficient
to result in the  issuance  of at least  1,000  shares  of  Common  Stock),  and
immediately  upon delivery of the  Conversion  Notice by the holder,  the holder
shall deliver to the  Corporation a facsimile of the certificate or certificates
representing the Conversion  Shares,  and concurrently  therewith shall send the
original  certificate or  certificates to the  Corporation's  transfer agent via
overnight  courier.  The Conversion Notice shall also contain a statement of the
name or names (with  addresses) in which the  certificate  or  certificates  for
Common Stock shall be issued.  Notwithstanding  the foregoing,  the  Corporation
shall not be required  to issue any  certificates  to any person  other than the
holder  thereof unless the  transaction is covered by an effective  registration
statement  under the  Securities  Act of 1933,  as amended  (the "1933  Act") or
unless the Corporation has obtained  reasonable  assurance that such transaction
is exempt from the registration requirements of the 1933 Act, and all applicable
state securities laws, including, if necessary in the reasonable judgment of the
Corporation  or its legal  counsel,  receipt of an opinion to such  effect  from
counsel  reasonably   satisfactory  to  the  Corporation.   Notwithstanding  the
foregoing,  such  opinion  would not be required  if the shares of Common  Stock
could,  upon  conversion,  be resold pursuant to Rule 144 or Rule 144A under the
1933 Act (unless such opinion is required by the Corporation's  transfer agent).
Promptly, but in no event later than three (3) trading days after the receipt of
the  Conversion  Notice and  subject to the  Corporation's  verification  of its
transfer   agent's   receipt  of  the  original   certificate  or   certificates
representing the Conversion Shares, the Corporation shall issue and deliver,  or
cause to be delivered,  to the holder of the Conversion Shares or his nominee or
nominees, a certificate or certificates for the number of shares of Common Stock
issuable upon the conversion of such Conversion Shares. Such conversion shall be
deemed to have been effected  immediately  prior to the close of business on the
date the Corporation  received the Conversion  Notice,  and shall be treated for
all  purposes as the holder or holders of record of such shares of Common  Stock
as of the close of business on such date.


                                      4





            (d) Conversion  Limit.  Notwithstanding  anything  contained in this
Section 4 to the  contrary,  a holder of shares of Series A Preferred  Stock may
not convert a number of shares of Series A Preferred  Stock that would result in
such holder beneficially owning shares of Common Stock in excess of 4.99% of the
Corporation's  then  outstanding  Common Stock upon such  conversion;  provided,
however, that the limitation described in this subsection 4(d) shall not prevent
a holder's  conversion  of shares of Series A Preferred  Stock at any other time
that does not result in the holder exceeding such limit.

            (e)   Conversion Factor Adjustments.

                  (i) In the  event the  Corporation  should at any time or from
time to time after the Purchase Date fix a record date for the effectuation of a
split or  subdivision of the  outstanding  shares of  Nonpreferred  Stock or the
determination of holders of Nonpreferred Stock entitled to receive a dividend or
other distribution  payable in additional shares of Nonpreferred Stock, then, as
of such record date (or, if no record date is fixed, as of the close of business
on the date on which the Board of Directors  adopts the  resolution  relating to
such dividend,  distribution,  split or subdivision), the Fixed Conversion Price
shall be multiplied by a fraction, the numerator of which shall be the number of
shares of Common Stock outstanding immediately prior thereto and the denominator
of which shall be the number of shares of Common Stock  outstanding  immediately
thereafter.  So long as any shares of Series A Preferred Stock are  outstanding,
the  Corporation  shall not fix a record date for,  or effect,  such a dividend,
distribution, split or subdivision on any shares of Nonpreferred Stock unless it
likewise  fixes a record  date for, or effects  such a  dividend,  distribution,
split or subdivision on all shares of Nonpreferred Stock.

                  (ii) If the number of shares of Nonpreferred Stock outstanding
at any time  after  the  Purchase  Date is  decreased  by a  combination  of the
outstanding shares of Nonpreferred  Stock, then following such combination,  the
Fixed Conversion Price shall be multiplied by a fraction, the numerator of which
shall be the  number of shares of Common  Stock  outstanding  immediately  prior
thereto  and the  denominator  of which  shall be the number of shares of Common
Stock  outstanding  immediately  thereafter.  So long as any  shares of Series A
Preferred Stock are outstanding, the Corporation shall not combine any shares of
Nonpreferred Stock unless it likewise combines all shares of Nonpreferred Stock.

            (f)  Recapitalization,   etc.  If  any  capital   reorganization  or
reclassification of the Common Stock of the Corporation (other than as set forth
in subsection  2(b)), or consolidation or merger of the Corporation with or into
another  corporation,  or the sale or conveyance of all or substantially  all of
its assets to another  corporation,  shall be effected,  then, as a condition of
such reorganization, reclassification, consolidation, merger or sale, lawful and
adequate  provision  shall be made whereby the holders of the Series A Preferred
Stock  shall  thereafter  have the right to  receive,  in lieu of the  shares of
Common Stock of the Corporation  immediately theretofore receivable with respect
to such shares of Series A Preferred Stock, such shares of stock,  securities or
assets as would have been issued or payable  with  respect to or in exchange for
the shares of Common Stock which such holders  would have held had the shares of
Series  A   Preferred   Stock   been   converted   immediately   prior  to  such
reorganization,  reclassification,  consolidation,  merger or sale.  In any such
case,  appropriate  provisions  shall be made with  respect  to the  rights  and
interests  of the holders of the Series A  Preferred  Stock to the end that such
conversion rights (including,  without limitation,  provisions for adjustment of
the  Conversion  Factor)  shall  thereafter be  applicable,  as nearly as may be
practicable in relation to any shares of stock,  securities or assets thereafter
deliverable upon the exercise thereof.  The Corporation shall not consummate any
such reorganization,  reclassification,  consolidation, merger or sale unless it
provides  the holders of the Series A Preferred  Stock at least twenty (20) days
advance notice thereof.

            (g) No  Impairment.  The  Corporation  will not, by amendment of its
Articles  of  Incorporation  or through  any  reorganization,  reclassification,
recapitalization,  transfer of assets, consolidation, merger, dissolution, issue
or sale of securities or any other  voluntary  action,  directly or  indirectly,
avoid or seek to avoid the  observance or  performance of any of the terms to be
observed or  performed  hereunder by the  Corporation,  but will at all times in
good faith assist in the carrying  out of all the  provisions  of this Section 4
and in the taking of all such action as may be necessary or appropriate in order
to  protect  the  conversion  and other  rights of the  holders  of the Series A
Preferred Stock against impairment.  Without limiting the foregoing, the Company
will not effect any transaction described in

                                      5





subsection 4(f), the result of which is to adversely affect any of the rights of
holders  of  Common  Stock  relative  to the  rights  of  holders  of any  other
Nonpreferred Stock.

            (h) Stock Transfer Taxes.  The issuance of stock  certificates  upon
the  conversion of the Series A Preferred  Stock shall be made without charge to
the converting  holder for any tax in respect of such issuance.  The Corporation
shall not,  however,  be required to pay any tax which may be payable in respect
of any  transfer  involved in the  issuance  and  delivery of shares in any name
other  than that of the  holder  of such  shares  of  Series A  Preferred  Stock
converted,  and the  Corporation  shall not be  required to issue or deliver any
such stock  certificate  unless and until the persons  requesting  the  issuance
thereof shall have paid to the Corporation the amount of such tax, if any.

            (i)   No Fractional Shares; Certificate as to Adjustments.

                  (i) No  fractional  shares shall be issued upon  conversion of
the Series A  Preferred  Stock.  In lieu of any  fractional  shares  which would
otherwise be issuable,  the  Corporation  shall pay cash equal to the product of
such  fraction  multiplied by the fair market value of one share of Common Stock
on the date of  conversion,  as determined by the closing price of such share on
the three (3) trading  days  immediately  preceding  the date of  conversion  as
reported on the Nasdaq National Market or such other principal securities market
on which the shares of Common Stock are traded (or, if the Corporation's  Common
Stock is not  traded  or  listed  on the  Nasdaq  National  Market  or any other
principal  securities  market,  the  average  of the  closing  bid prices in the
over-the-counter  market on such days or  reported  by Nasdaq or any  comparable
system, or if not so reported, as reported by any New York Stock Exchange member
firm selected by the Corporation for such purpose).
                  (ii) Upon the occurrence of each adjustment or readjustment of
the Conversion  Factor of Series A Preferred Stock pursuant to subsections  4(e)
or (f), the Corporation,  at its expense, shall promptly compute such adjustment
or  readjustment  in accordance with the terms hereof and prepare and furnish to
each  holder  of Series A  Preferred  Stock a  certificate  setting  forth  such
adjustment  or  readjustment  and  the  method  upon  which  it  is  based.  The
Corporation  shall, upon the written request at any time of any holder of Series
A  Preferred  Stock,  furnish  or cause to be  furnished  to such  holder a like
certificate  setting  forth  (A)  such  adjustment  or  readjustment,   (B)  the
Conversion Factor at the time in effect,  and (C) the number of shares of Common
Stock and the  amount,  if any,  of other  property  which at the time  would be
received upon the conversion of a share of Series A Preferred Stock.

            (j)  Notices  of  Record  Date.  In the  event of any  taking by the
Corporation  of a record  of the  holders  of any  class of  securities  for the
purpose of  determining  the  holders  thereof  who are  entitled to receive any
dividend  (other  than a cash  dividend)  or other  distribution,  any  right to
subscribe for, purchase or otherwise acquire any shares of stock of any class of
any other securities or property, or to receive any other right, the Corporation
shall mail to each holder of Series A Preferred Stock, at least twenty (20) days
prior to the date specified  therein,  a notice specifying the date on which any
such record is to be taken for the  purpose of such  dividend,  distribution  or
right, and the amount and character of such dividend, distribution or right.

            (k) Reservation of Stock Issuable Upon  Conversion.  The Corporation
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock solely for the purpose of effecting the conversion of the
shares of the Series A Preferred Stock,  free from any preemptive right or other
obligation, such number of its shares of Common Stock as shall from time to time
be sufficient to effect the conversion of all outstanding shares of the Series A
Preferred Stock; and if at any time the number of authorized but unissued shares
of Common Stock shall not be sufficient  to effect the  conversion of all of the
then outstanding  shares of the Series A Preferred  Stock,  then, in addition to
such  other  remedies  as shall be  available  to the  holder  of such  Series A
Preferred  Stock,  the  Corporation  will take such  corporate  action as may be
necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as shall be sufficient for such purposes. The Corporation shall
prepare  and  shall  use its best  efforts  to  obtain  and  keep in force  such
governmental or regulatory permits or other  authorization as may be required by
law, and shall comply with all requirements as to registration, qualification or
listing of the Common  Stock,  in order to enable the  Corporation  lawfully  to
issue and  deliver  to each  holder of record of Series A  Preferred  Stock such

convertible into shares of Common Stock.

      5. Voting Rights.  The holders of Series A Preferred Stock shall vote as a
class on all matters  required by applicable law to be submitted to such holders
for a vote.  Until  conversion of shares of Series A Preferred Stock into Common
Stock,  as provided  herein,  the holders of Series A Preferred  Stock shall not
have or exercise any rights as holders of Common Stock solely by virtue of being
a holder of Series A Preferred Stock.

      6.    Protective Provisions.

            (a) So long as shares of Series A Preferred  Stock are  outstanding,
the  Corporation  shall not,  without  first  obtaining the approval (by vote or
written consent) of the holders of all of the then outstanding  shares of Series
A Preferred  Stock  (voting in  accordance  with Section 5), alter or change the
rights,  preferences or privileges of the shares of Series A Preferred  Stock so
as to affect adversely the shares; and

            (b) So long as shares of Series A Preferred  Stock are  outstanding,
the  Corporation  shall not,  without  first  obtaining the approval (by vote or
written  consent)  of the  holders  of 66.6% of the then  outstanding  shares of
Series A Preferred Stock (voting in accordance with Section 5), (i) increase the
number of authorized shares of Series A Preferred Stock, create or designate any
new series of stock (including without  limitation,  any Preferred Stock) or any
other securities  convertible into equity securities of the corporation having a
preference  over, or being on a parity with,  the Series A Preferred  Stock with
respect to voting,  dividends,  distribution of assets or conversion  rights, or
(ii) amend the Articles of  Incorporation  or Bylaws of the  Corporation or take
any action or enter into any other  agreements  which  prohibit or conflict with
the Corporation's  obligations hereunder with respect to the holders of Series A
Preferred Stock.

      7.  Status  of  Converted  Stock.  In the  event  any  shares  of Series A
Preferred Stock shall be converted  pursuant to Section 4 hereof,  the shares so
converted  shall be canceled and thereupon  restored to the status of authorized
but  unissued  Preferred  Stock not  designated  as to class or  series  and the
Corporation  shall not thereafter,  through its Board of Directors or otherwise,
designate any such undesignated  shares of Preferred Stock as Series A Preferred
Stock or any other  series of  Preferred  Stock  having  rights and  preferences
substantially similar to those of Series A Preferred Stock so long as any shares
of Series A Preferred Stock are outstanding.

      8.    Redemption.

            (a) Mandatory  Redemption.  Upon the occurrence of any of the events
described in  subsections  8(a)(i)  through  8(a)(vi)  hereof (each a "Mandatory
Event"),  any  holder of shares of Series A  Preferred  Stock that have not been
converted  into  Common  Stock  may  elect to sell,  and the  Corporation  shall
repurchase,  any or all of such holder's  shares of Series A Preferred  Stock as
may be designated in the  Redemption  Notice (as defined in Section 8(c) below),
at a price  equal to the  Liquidation  Preference  (plus any  accrued and unpaid
dividends or  distributions  thereon) for each share of Series A Preferred Stock
being  redeemed  plus the  product of the number of shares of Common  Stock into
which such shares of Series A Preferred Stock are then convertible multiplied by
an amount  equal to the  difference  between (x) the  average  closing bid price
quoted on a share of Common  Stock on the Nasdaq  National  Market for the three
(3) trading days immediately  following the date of the Redemption Notice (or if
the  Corporation's  Common Stock is not traded or listed on the Nasdaq  National
Market or any other principal  securities market, the average of the closing bid
prices in the over-the-counter  market on such days as reported by Nasdaq or any
comparable  system,  or if not so  reported,  as  reported by any New York Stock
Exchange  member firm selected by the  Corporation for such purpose) and (y) the
Conversion Factor:

                                      7





                   (i) on the date that is three years after the Purchase Date
and at any time thereafter;

                  (ii)  immediately   prior  to  the  consummation  of  a  sale,
conveyance  or  disposition  of all or  substantially  all of the  assets of the
Corporation or the  effectuation  by the  Corporation or its  shareholders  of a
transaction  or series of  related  transactions  in which  more than 50% of the
voting power of the Corporation is transferred or otherwise  disposed of (each a
"Control  Transaction")  or a consolidation or merger of the Corporation with or
into any other corporation or corporations (other than a merger that is not part
of a Control  Transaction  and  that,  pursuant  to the  provisions  of  Section
607.1103(7) of the FBCA,  does not require  approval by the  shareholders of the
Corporation);

                  (iii)  at any time on or after  the date on which  the  Common
Stock of the  Corporation  is no longer  quoted on the  Nasdaq  National  Market
System or other principal securities market;

                  (iv) at any  time  on or  after  the  later  of (x)  150  days
following  the date on which the Form 10-K for the fiscal year ended October 31,
1996 is filed by the  Corporation  with the Securities  and Exchange  Commission
(the "SEC"), and (y) July 14, 1997, if: (A) a registration statement registering
the shares of Common Stock  issuable  upon  conversion of the Series A Preferred
Stock has not been declared  effective by the SEC; or (B) at any time after such
effective  date if the SEC  shall  have  issued  any stop  order or other  order
suspending the effectiveness of such registration statement or the effectiveness
of such  registration  statement has been  suspended or has lapsed for any other
reason or the registration statement is unavailable for use, and the Corporation
shall have  failed to  reestablish  the  effectiveness  or  availability  of the
registration  statement  within thirty (30) days after the SEC's order or within
thirty (30) days after the date upon which the effectiveness of the registration
statement  was suspended or lapsed or became  unavailable  for use for any other
reason,  as the case may be; or (C) an  insufficient  number of shares of Common
Stock have been  registered  to allow the  conversion of the all of the Series A
Preferred  Stock,  in which  case,  the  Corporation  shall only be  required to
repurchase  those  shares  of  Series A  Preferred  Stock for which no shares of
Common Stock have been registered;

                  (v) at any time on or after  the date on which  the Form  10-K
for the fiscal year ended October 31, 1996 is filed by the Corporation  with the
SEC if the  auditors'  letter to the  Corporation  with respect to the financial
statements contained in such Form 10-K is qualified in any respect; or

                  (vi) at any  time on or after  the  date on which a holder  or
holders of Series A Preferred Stock or Warrants has determined that a conversion
of such shares or exercise of such Warrants,  when taken together with all other
past and potential  future  conversions of Series A Preferred Stock or exercises
of Warrants,  will result in such holder or holders having  acquired that number
of shares of Common  Stock  exceeding  19.99% of the  Corporation's  outstanding
Common Stock as of the Purchase Date; provided however,  that in each such case,
the mandatory  redemption by the  Corporation  shall only apply to the number of
shares of Series A Preferred  Stock the conversion of which causes the number of
shares of Common Stock to be in excess of such limits.

            (b)   Optional Redemption.

                  (i) At any time after the first  anniversary  of the  Purchase
Date and provided that there exists an effective  registration  statement  filed
pursuant to the 1933 Act covering the  Corporation's  Common Stock issuable upon
conversion  of the  Series  A  Preferred  Stock,  the  Corporation  may  issue a
Redemption Notice (as defined below) to redeem all of the outstanding  shares of
Series A Preferred Stock, which Redemption Notice shall be delivered on the next
business day following the date on which the closing bid price of a share of the
Corporation's  Common Stock on the Nasdaq  National  Market,  or other principal
securities  market on which its Common Stock is traded (or if the  Corporation's
Common Stock is not traded or listed on the Nasdaq  National Market or any other
principal  securities  market,  the  closing  bid price in the  over-the-counter
market as reported by Nasdaq or any comparable system, or if not so reported, as
reported by any New York Stock Exchange  member firm selected by the Corporation
for such purpose), for each of the five (5) consecutive trading days immediately
prior to the date of receipt by the Investors of such Redemption Notice is at or
greater  than 150% of the then Fixed  Conversion  Price as adjusted  pursuant to
Section  4(e) hereof.  The purchase  price per share for such shares of Series A
Preferred Stock to be redeemed by the

                                      8





Corporation  under this  subsection  8(b)(i)  shall be equal to the  Liquidation
Preference (plus any accrued and unpaid dividends or distributions thereon).

                  Each of the  Investors  shall have  ninety (90) days after its
receipt of a Redemption  Notice  delivered  pursuant to this Section  8(b)(i) to
deliver a Conversion Notice or Notices to the Corporation with respect to any or
all of the shares of Series A  Preferred  Stock  identified  by such  Redemption
Notice.  Upon an  Investor's  delivery  of any  such  Conversion  Notice  to the
Corporation,  the  provisions  of Section 4 hereof  shall apply with  respect to
those shares of Series A Preferred Stock identified in the Conversion Notice. If
an Investor does not deliver a Conversion  Notice or Notices covering all of the
shares of Series A Preferred  Stock held by it within ninety (90) days after its
receipt of the Redemption Notice, the Corporation shall have the right to redeem
the remaining  shares of Series A Preferred  Stock for a purchase price equal to
the  Liquidation   Preference   (plus  any  accrued  and  unpaid   dividends  or
distributions  thereon) for such shares. The ninety (90) day period set forth in
this  Section  8(b)(i)  shall be extended  by the number of days during  which a
registration  statement is not  effective or otherwise  not available for use by
the Investors.

                  (ii) In the event that the closing bid price of a share of the
Corporation's  Common Stock on the Nasdaq  National  Market,  or other principal
securities  market on which its Common Stock is traded (or if the  Corporation's
Common Stock is not traded or listed on the Nasdaq  National Market or any other
principal  securities  market,  the  closing  bid price in the  over-the-counter
market as reported by Nasdaq or any comparable system, or if not so reported, as
reported by any New York Stock Exchange  member firm selected by the Corporation
for such  purpose),  for five (5)  consecutive  trading  days is at or less than
$4.50  and  the  Corporation  receives  a  Conversion  Notice  from  one or more
Investors within three (3) business days thereafter, the Corporation may, within
three (3)  business  days after the  Corporation's  receipt  of such  Conversion
Notice,  elect to redeem the shares of Series A Preferred  Stock  identified  by
such Conversion Notice for a purchase price equal to the Liquidation  Preference
(and any accrued and unpaid dividends or  distributions  thereon) for each share
of Series A  Preferred  Stock being  redeemed  plus the product of the number of
shares of Common  Stock into which the  shares of Series A  Preferred  Stock are
then convertible multiplied by an amount equal to the difference between (x) the
average  closing  bid  price  quoted on a share of  Common  Stock on the  Nasdaq
National Market for the three (3) trading days immediately following the date of
the  Redemption  Notice (or if the  Corporation's  Common Stock is not traded or
listed on the Nasdaq National Market or any other principal  securities  market,
the  average of the closing  bid prices in the  over-the-counter  market on such
days as reported by Nasdaq or any comparable  system, or if not so reported,  as
reported by any New York Stock Exchange  member firm selected by the Corporation
for such purpose) and (y) the Conversion Factor.

            (c) The party or parties  effecting the redemption  rights described
in this Section 8 shall provide written notice to the Corporation or the holders
of  shares  of  Series A  Preferred  Stock  as the case may be (the  "Redemption
Notice"), which Redemption Notice shall contain the number of shares of Series A
Preferred  Stock to be redeemed and the purchase price per share,  determined in
accordance  herewith.  No later  than (i) in the case of a  redemption  effected
pursuant to  subsections  8(a) or 8(b)(ii),  five (5) days after delivery of the
applicable  Redemption  Notice,  or (ii) in the  case of a  redemption  effected
pursuant to  subsection  8(b)(i),  ninety-seven  (97) days (which  period may be
extended as  provided in the last  sentence  of Section  8(b)(i)  hereof)  after
delivery of the applicable  Redemption Notice, the holders of Series A Preferred
Stock shall deliver their share  certificates  to the  Corporation,  endorsed in
blank  or  with  separate  stock  powers,   and,  upon  receipt  of  such  share
certificates,  the  Corporation  shall deliver the full purchase  price for such
shares in  immediately  available  funds to the  holders  via wire  transfer  or
cashier's check, together with certificates for any shares of Series A Preferred
Stock that remain outstanding, if any.

      IN WITNESS WHEREOF,  the Corporation has caused the foregoing  Articles of
Amendment to the Articles of Incorporation to be signed on December 20, 1996.
