         and Series RR Preferred Stock are then convertible. In the event the

         Certificate of Determination of Preferences (the "Rights Declaration
         Date") (i) declare any dividend on Common Stock payable in shares of
         Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
         combine the

                                        2



         outstanding Common Stock into a smaller number of shares, then in each
         such case, the amount of Common Stock or other consideration to which
         holders of shares of Series RR Preferred Stock were entitled
         immediately prior to such event under the preceding sentence shall be
         adjusted as set forth in Section 4(C) hereof.

                           (B)      The Corporation shall declare a dividend or
         distribution on the Series RR Preferred Stock as provided in paragraph
         (A) above prior to declaring a dividend payable on shares of Common
         Stock.

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

                           (A)      Each holder of Series RR Preferred Stock is
         entitled to a number of votes equal to the number of shares of Common
         Stock into which the holder's Series RR Preferred Stock is then
         convertible. Except as provided by law, the Common Stock and Series RR
         Preferred Stock (and any series of Preferred Stock which may be
         subsequently authorized which is convertible into shares of Common
         Stock and which has voting rights equal to the number of shares of
         Common Stock into which such series of Preferred Stock is then
         convertible) shall vote together as a single class on all matters to
         come before the shareholders for approval. In the event the Corporation
         shall at any time after the Rights Declaration Date (i) declare any
         dividend on Common Stock payable in shares of Common Stock, (ii)
         subdivide the outstanding Common Stock, or (iii) combine the
         outstanding Common Stock into a smaller number of shares, then in each
         such case the number of votes per share to which holders of shares of
         Series RR Preferred Stock were entitled immediately prior to such event
         shall be adjusted as set forth in Section 4(C) hereof.

                           (B)      Except as otherwise provided herein or by
         law, the holders of shares of Series RR Preferred Stock and the holders
         of shares of Common Stock (and any series of Preferred Stock which may
         be subsequently authorized which is convertible into shares of Common
         Stock and which has voting rights equal to the number of shares of
         Common Stock into which such series of Preferred Stock is then
         convertible) shall vote together as one class on all matters submitted
         to a vote of shareholders of the Corporation.

                           (C)      Except as required by law or under Section 8
         hereof, holders of Series RR Preferred Stock shall have no special
         voting rights and their consent shall not be 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. Conversion Rights.

                           (A)      Each holder of Series RR Preferred Stock
         may, at any time, in such holder's sole discretion, convert all or any
         part of such holder's shares of Series RR Preferred Stock into fully
         paid and nonassessable shares of Common Stock at the rate of ten (10)
         shares of Common Stock for each share of Series RR Preferred Stock
         surrendered for conversion.

                           (B)      Such conversion may be effected by surrender
         of such holder's certificate or certificates for the shares of Series
         RR Preferred Stock to be converted, duly endorsed, at the principal
         office of the Corporation, with a written notice stating (i) that such
         holder elects to convert all or a specified number of shares of Series
         RR Preferred Stock into

                                        3



         shares of Common Stock, and (ii) the name in which such holder desires
         a certificate for the shares of Common Stock to be issued. Promptly
         thereafter, the Company shall issue and deliver to such holder a
         certificate for the number of shares of Common Stock to which such
         holder shall be entitled. Such conversion shall be deemed to have been
         made at the close of business on the date of such surrender, and such
         holder shall be treated for all purposes as the record holder of such
         shares of Common Stock on that date.

                           (C)      In the event the Corporation shall at any
         time after the Rights Declaration Date (i) declare any dividend on
         Common Stock payable in shares of Common Stock, (ii) subdivide the
         outstanding Common Stock, or (iii) combine the outstanding Common Stock
         into a smaller number of shares, then, in each case, the number of
         shares of Common Stock issuable upon the conversion of each share of
         Series RR Preferred Stock 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 are outstanding
         immediately prior to such event.

                           (D)      In the event the Corporation shall at any
         time or from time to time after the Rights Declaration Date make or
         issue, or fix a record date for the determination of holders of Common
         Stock entitled to receive, a dividend or other distribution payable in
         securities of the Corporation or any of its subsidiaries, or of any
         other corporation or third party, other than in shares of Common Stock,
         then, in each such event, provisions shall be made so that the holders
         of Series RR Preferred Stock shall receive, upon the conversion
         thereof, securities of the Corporation or any of its subsidiaries or of
         any other corporation or third party which they would have received had
         their stock been converted into Common Stock on the date of such event.

                  Section 5. Reacquired Shares. Any shares of Series RR
         Preferred Stock purchased or otherwise acquired by the Corporation in
         any manner whatsoever shall be retired and canceled 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 to be created by
         resolution or resolutions of the Board of Directors, subject to the
         conditions and restrictions on issuance set forth herein.

                  Section 6. Liquidation, Dissolution or Winding Up.

                           (A)      Upon any liquidation (voluntary or
         otherwise), dissolution or winding up of the Corporation, following the
