<PAGE>

The relative rights, preferences and limitations of the shares of
each class are as follows:

      Preferred. The Board of Directors is authorized to adopt at any time, or
from time to time, amendments to the Certificate of Incorporation in respect of
any unissued and/or treasury shares of preferred stock, and thereby to fix or
change the division of shares of the preferred stock into classes and/or into
series within any class or classes, and the determination of the relative
rights, preferences and limitations of the shares of any class or series. The
authority of the Board with respect to each class or series of preferred stock
shall include, but not be limited to, determination of the following:

      (a) The number of shares constituting that class or series and the
distinctive designation of that class or series;

      (b) The dividend rate on the shares of that class or series, whether
dividends shall be cumulative, and, if so, from which dates or dates;

      (c) Whether that class or series shall have voting rights, in addition to
any voting rights provided by Law, and, if so, the terms of such voting rights;

      (d) Whether that class or series shall have conversion privileges and, if
so, the terms and conditions of such conversion, including provision for
adjustment of the conversion rate in such events as the Board of Directors shall
determine;

      (e) Whether or not shares of that class or series shall be redeemable,

or series as may be permitted or required by Law.

      Common. Each share of common stock shall be entitled to one vote on all
matters submitted to a vote of stockholders. The common stockholders shall be
entitled to such dividends as may be declared by the Board of Directors from
time to time, provided that required dividends, if any, on the preferred stock

winding up, whether voluntary or involuntary, of the corporation, the assets and
funds of the corporation available for distribution to stockholders, and
remaining after the payment to holders of preferred stock of the amounts to
which they are entitled, shall be divided and paid to the holders of the common
stock according to their respective shares.

      FIFTH: (a) The number of directors which shall constitute the whole Board
of Directors shall be not less than three nor more than fifteen. The exact

any incumbent directors.

      (b) The Board of Directors shall be divided into three classes, as nearly
equal in number as the then total number of directors constituting the whole
Board permits. At the annual meeting of stockholders in 1986, directors of the
first class shall be elected to hold office for a term expiring at the next
succeeding annual meeting, directors of the second class shall be elected to
hold office for a term expiring at the second succeeding annual meeting and
directors of the third class shall be elected to hold office for a term expiring
at the third succeeding annual meeting. At each annual meeting of stockholders
following such initial classification and election, the number of directors
equal to the number of the class whose terms expire at the time of such meeting
shall be elected to hold office until the third succeeding annual meeting of
stockholders. Each director shall hold office until his successor is elected and
qualified, or until his earlier resignation or removal.

      (c) Newly elected directorships resulting from any increase in the
authorized number of directors and any vacancies in the Board of Directors
resulting from death, resignation, retirement, disqualification, removal from
office or other cause may be filled only by a majority vote of the entire Board,
and directors so chosen shall hold office for a term expiring at the annual
meeting of stockholders at which the term of the class to which they have been
elected expires.

                  (c) (if applicable) the highest preferential amount per share
            to which the holders of shares of such class would be entitled in
            the event of any voluntary or involuntary liquidation, dissolution
            or winding up of the affairs of the Corporation, regardless of
            whether the Business Combination to be consummated constitutes such
            an event.

      have previously acquired shares of a particular class, the form of
      consideration to be received by holders of such class shall be cash.
