       (Pursuant to Section 151 of the Delaware General Corporation Law)


         Nu Horizons Electronics Corp., a corporation organized and existing
under the General Corporation Law of the State of Delaware (hereinafter called
the "Corporation"), hereby certifies that the following resolution was adopted
by the Board of Directors of the Corporation as required by Section 151 of the
General Corporation Law at a meeting duly called and held on May 26, 1999:

          RESOLVED, that pursuant to the authority granted to and vested in the
Board of Directors of this Corporation (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the Certificate
of Incorporation, as amended, the Board of Directors hereby adopts, effective as
of June 9, 1999, a Certificate of Designation establishing the Series A Junior
Participating Preferred Stock, and the relative rights, preferences, and
limitations of such Series A Junior Participating Preferred Stock, as follows:

          Series A Junior Participating Preferred Stock:

          Section 1. Designation and Amount. The shares of such series shall be
                     ----------------------
designated as "Series A Junior Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares constituting the Series A Preferred
Stock shall be 20,000. Such number of shares may be increased or decreased by
resolution of the Board of Directors; provided, that no decrease shall reduce
the number of shares of Series A Preferred Stock to a number less than the
number of shares then outstanding plus the number of shares reserved for
issuance upon the exercise of outstanding options, rights or warrants or upon
the conversion of any outstanding securities issued by the Corporation
convertible into Series A Preferred Stock.
<PAGE>

         Section 2.   Dividends and Distributions.

                (A)   Subject to the rights of the holders of any shares of any
         series of Preferred Stock, par value $1.00 per share (the "Preferred
         Stock"), of the Corporation (or any similar stock) ranking prior and
         superior to the Series A Preferred Stock with respect to dividends, the
         holders of shares of Series A Preferred Stock, in preference to the
         holders of Common Stock, par value $.0066 per share (the "Common
         Stock"), of the Corporation, and of any other junior stock, shall be
         entitled to receive, when, as and if declared by the Board of Directors
         out of funds legally available for the purpose, quarterly dividends
         payable in cash on the first day of March, June, September and December
         in each year (each such date being referred to herein as a "Quarterly
         Dividend Payment Date"), commencing on the first Quarterly Dividend
         Payment Date after the first issuance of a share or fraction of a share
         of Series A Preferred Stock, in an amount per share (rounded to the
         nearest cent) equal to the greater of (a) $1 or (b) subject to the
         provision for adjustment hereinafter set forth, 1,000 times the
         aggregate per share amount of all cash dividends, and 1,000 times the
         aggregate per share amount (payable in kind) of all non-cash dividends
         or other distributions, other than a dividend payable in shares of
         Common Stock or a subdivision of the outstanding shares of Common Stock
         (by reclassification or otherwise), declared on the Common Stock since
         the immediately preceding Quarterly Dividend Payment Date or, with
         respect to the first Quarterly Dividend Payment Date, since the first
         issuance of any share or fraction of a share of Series A Preferred
         Stock. In the event the Corporation shall at any time after the date
         hereof declare or pay any dividend on the Common Stock payable in
         shares of Common Stock, or effect a subdivision or combination or
         consolidation of the outstanding shares of Common Stock (by
         reclassification or otherwise than by payment of a dividend in shares
         of Common Stock) into a greater or lesser number of shares of Common
         Stock, then in each such case the amount to which holders of shares of
         Series A Preferred Stock were entitled immediately prior to such event
         under clause (b) of the preceding sentence shall be adjusted by
         multiplying such amount by a fraction, the numerator of which is the
         number of shares of Common Stock outstanding immediately after such
         event and the denominator of which is the number of shares of Common
         Stock that were outstanding immediately prior to such event.

                (B)   The Corporation shall declare a dividend or distribution
         on the Series A Preferred Stock as provided in paragraph (A) of this
         Section immediately after it declares a dividend or distribution on the
         Common Stock (other than a dividend payable in shares of Common Stock);
         provided that, in the event no dividend or distribution shall have been
         declared on the Common Stock during the period between any Quarterly
         Dividend Payment Date and the next subsequent Quarterly Dividend
         Payment Date, a dividend of $1 per share on the Series A Preferred
         Stock shall nevertheless be payable on such subsequent Quarterly
         Dividend Payment Date.
<PAGE>

          (C)   Dividends shall begin to accrue and be cumulative on outstanding
     shares of Series A Preferred Stock from the Quarterly Dividend Payment Date
     next preceding the date of issue of such shares, unless the date of issue
     of such shares is prior to the record date for the first Quarterly Dividend
     Payment Date, in which case dividends on such shares shall begin to accrue
     from the date of issue of such shares, or unless the date of issue is a
     Quarterly Dividend Payment Date or is a date after the record date for the
     determination of holders of shares of Series A Preferred Stock entitled to
     receive a quarterly dividend and before such Quarterly Dividend Payment
     Date, in either of which events such dividends shall begin to accrue and be
     cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid
     dividends shall not bear interest. Dividends paid on the shares of Series A
     Preferred Stock in an amount less than the total amount of such dividends
     at the time accrued and payable on such shares shall be allocated pro rata
     on a share-by-share basis among all such shares at the time outstanding.
     The Board of Directors may fix a record date for the determination of
     holders of shares of Series A Preferred Stock entitled to receive payment
     of a dividend or distribution declared thereon, which record date shall be
     not more than 60 days prior to the date fixed for the payment thereof.

     Section 3. Voting Rights. The holders of shares of Series A Preferred
                --------------
Stock shall have the following voting rights:

          (A)   Subject to the provision for adjustment hereinafter set forth,
     each share of Series A Preferred Stock shall entitle the holder thereof to
     1,000 votes on all matters submitted to a vote of the stockholders of the
     Corporation. In the event the Corporation shall at any time after the date
     hereof declare or pay any dividend on the Common Stock payable in shares of
     Common Stock, or effect a subdivision or combination or consolidation of
     the outstanding shares of Common Stock (by reclassification or otherwise
     than by payment of a dividend in shares of Common Stock) into a greater or
     lesser number of shares of Common Stock, then in each such case the number
     of votes per share to which holders of shares of Series A Preferred Stock
     were entitled immediately prior to such event shall be adjusted by
     multiplying such number by a fraction, the numerator of which is the number
     of shares of Common Stock outstanding immediately after such event and the
     denominator of which is the number of shares of Common Stock that were
     outstanding immediately prior to such event.

          (B)   Except as otherwise provided herein, in any other Certificate of
     Designation creating a series of Preferred Stock or any similar stock, or
     by law, the holders of shares of Series A Preferred Stock and the holders
     of shares of Common Stock and any other capital stock of the Corporation
     having general voting rights shall vote together as one class on all
     matters submitted to a vote of stockholders of the Corporation.

          (C)   Except as set forth herein, or as otherwise provided by law,
     holders of Series A Preferred Stock shall have no special voting rights and
     their consent shall not be
<PAGE>

     required (except to the extent they are entitled to vote with holders of
     Common Stock as set forth herein) for taking any corporate action.

     Section 4.     Certain Restrictions.
                    ---------------------

          (A)       Whenever quarterly dividends or other dividends or
     distributions payable on the Series A Preferred Stock as provided in
     Section 2 are in arrears, thereafter and until all accrued and unpaid
     dividends and distributions, whether or not declared, on shares of Series A
     Preferred Stock outstanding shall have been paid in full, the Corporation
     shall not:

                    (i)       declare or pay dividends, or make any other
          distributions, on any shares of stock ranking junior (either as to
          dividends or upon liquidation, dissolution or winding up) to the
          Series A Preferred Stock;

                    (ii)      declare or pay dividends, or make any other
          distributions, on any shares of stock ranking on a parity (either as
          to dividends or upon liquidation, dissolution or winding up) with the
          Series A Preferred Stock, except dividends paid ratably on the Series
          A Preferred Stock and all such parity stock on which dividends are
          payable or in arrears in proportion to the total amounts to which the
          holders of all such shares are then entitled;

                    (iii)     redeem or purchase or otherwise acquire for
          consideration shares of any stock ranking junior (either as to
          dividends or upon liquidation, dissolution or winding up) to the
          Series A Preferred Stock, provided that the Corporation may at any
          time redeem, purchase or otherwise acquire shares of any such junior
          stock in exchange for shares of any stock of the Corporation ranking
          junior (either as to dividends or upon dissolution, liquidation or
          winding up) to the Series A Preferred Stock; or

                    (iv)      redeem or purchase or otherwise acquire for
          consideration any shares of Series A Preferred Stock, or any shares of
          stock ranking on a parity with the Series A Preferred Stock, except in
          accordance with a purchase offer made in writing or by publication (as
          determined by the Board of Directors) to all holders of such shares
          upon such terms as the Board of Directors, after consideration of the
          respective annual dividend rates and other relative rights and
          preferences of the respective series and classes, shall determine in
          good faith will result in fair and equitable treatment among the
          respective series or classes.

          (B)       The Corporation shall not permit any subsidiary of the
     Corporation to purchase or otherwise acquire for consideration any shares
     of stock of the Corporation unless the Corporation could, under paragraph
     (A) of this Section 4, purchase or otherwise acquire such shares at such
     time and in such manner.
<PAGE>

         Section 5. Reacquired Shares. Any shares of Series A Preferred Stock
                    ------------------
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Preferred Stock and may be reissued as part of a new series of Preferred Stock
subject to the conditions and restrictions on issuance set forth herein, in the
Certificate of Incorporation, as amended, or in any other Certificate of
Designation creating a series of Preferred Stock or any similar stock or as
otherwise required by law.

         Section 6. Liquidation, Dissolution or Winding Up. Upon any
                    ---------------------------------------
liquidation, dissolution or winding up of the Corporation, no distribution shall
be made (1) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Series A
Preferred Stock unless, prior thereto, the holders of shares of Series A
Preferred Stock shall have received $1,000 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Series A
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 1,000
times the aggregate amount to be distributed per share to holders of shares of
Common Stock, or (2) to the holders of shares of stock ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with the
Series A Preferred Stock, except distributions made ratably on the Series A
Preferred Stock and all such parity stock in proportion to the total amounts to
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding up. In the event the Corporation shall at any time after
the date hereof declare or pay any dividend on the Common Stock payable in
shares of Common Stock, or effect a subdivision or combination or consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise than
by payment of a dividend in shares of Common Stock) into a greater or lesser
number of shares of Common Stock, then in each such case the aggregate amount to
which holders of shares of Series A Preferred Stock were entitled immediately
prior to such event under the proviso in clause (l)of the preceding sentence
shall be adjusted by multiplying such amount by a fraction the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

         Section 7. Consolidation, Merger, etc. In case the Corporation shall
                    ---------------------------
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 1,000 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Corporation shall at any time after the date hereof declare or
