amended by adding the following provision as Article THIRD.F:

         THIRD.F: A series of preferred stock, $1.00 par value per share, of the
Corporation (such preferred stock being herein referred to as "Preferred Stock,"
which term shall include any additional shares of preferred stock of the same
class heretofore or hereafter authorized to be issued by the Corporation),
Consisting of 120,000 shares is hereby created, and the number, designation,
relative rights, preferences and limitations thereof are as follows:

         Section 1. Designation and Number. There shall be a series of Preferred
Stock of the Corporation which shall be designated as "Series 2 Junior
Participating Preferred Stock," $1.00 par value per share (hereinafter called
"Series 2 Junior Preferred Stock"), and the number of shares constituting such
series shall be 120,000. Such number of shares may be increased or decreased by
resolution of the Board of Directors of the Corporation and by the filing of a
Certificate of Amendment of Certificate of Incorporation pursuant to the
provisions of the New York Business Corporation Law stating that such increase
or reduction has been so authorized; provided, however, that no decrease shall
reduce the number of shares of Series 2 Junior Preferred Stock to a number less
than that of the shares then outstanding plus the number of shares of Series 2
Junior Preferred Stock issuable upon exercise of outstanding rights, options or
warrants or upon conversion of outstanding securities issued by the Corporation.

         Section 2. Dividends and Distributions.

         (A) Subject to the prior and superior rights of the holders of any
shares of any series of Preferred Stock ranking prior and superior to the shares
of Series 2 Junior Preferred Stock with respect to dividends, the holders of
shares of Series 2 Junior Preferred Stock shall be entitled to receive, when, as
and if declared by the Board of Directors of the Corporation out of funds
legally available for such purpose, quarterly dividends payable in cash to
holders of record on the last business 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 2 Junior Preferred Stock, in an amount per share (rounded to the nearest
cent) equal to the greater of (a) $1.00 and (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 (hereinafter defined) or a subdivision of the
outstanding shares of Common Stock (by reclassification or otherwise), declared
on the common stock, par value $0.625 per share, of the Corporation (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 2 Junior Preferred Stock.
If the Corporation shall at any time following July 24,1998 (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 amount to which holders of
shares of Series 2 Junior Preferred Stock were entitled immediately prior to
such event under clause (b) of the preceding sentence shall be adjusted by
multiplying each 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 2 Junior Preferred Stock as provided in paragraph (A) above at the time
it declares a dividend or distribution on the Common Stock (other than a
dividend payable in shares of Common Stock).

         (C) No dividend or distribution (other than a dividend payable in
shares of Common Stock) shall be paid or payable to the holders of shares of
Common Stock unless, prior thereto, all accrued but unpaid dividends to the date
of such dividend or distribution shall have been paid to the holders of shares
of Series 2 Junior Preferred Stock.

         (D) Dividends shall begin to accrue and be cumulative on outstanding
shares of Series 2 Junior Preferred Stock from the Quarterly Dividend Payment
Date next preceding the date of issue of such shares of Series 2 Junior
Preferred Stock, 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 2 Junior
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 2 Junior 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 of the Corporation may fix a record date for
the determination of holders of shares of Series 2 Junior Preferred Stock
entitled to receive payment of a dividend or distribution declared thereon,
which record date shall be no more than 30 days prior to the date fixed for the
payment thereof.

         Section 3. Voting Rights. The holders of shares of Series 2 Junior
Preferred Stock shall have the following voting rights:

         (A) Subject to the provision for adjustment hereinafter set forth, each
one one-thousandth of a share of Series 2 Junior Preferred Stock shall entitle
the holder thereof to one vote on all matters submitted to a vote of the
shareholders of the Corporation. If the Corporation shall at any time following
July 24,1998 (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the Outstanding shares of 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 2 Junior 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 or in the Restated Certificate
of Incorporation, as amended from time to time, or by law, the holders of shares
of Series 2 Junior 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 shareholders of
the Corporation.

         (C) (i) Whenever, at any time or times, dividends payable on any share
or shares of Series 2 Junior Preferred Stock shall be in arrears in an amount
equal to at least six full quarterly dividends (whether or not declared and
whether or not consecutive), the holders of record of the outstanding Preferred
Stock shall have the exclusive right, voting separately as a single class, to
elect a total of two directors of the Corporation. Such two directors shall be
elected initially at a special meeting of shareholders of the Corporation or at
the Corporation's next annual meeting of shareholders, and subsequently at each
annual meeting of shareholders, as provided below. The term of office of the two
directors so elected shall end on the date of the annual meeting following such
election. At elections for such directors, the holders of shares of Series 2
Junior Preferred Stock shall be entitled to cast one vote for each one
one-thousandth of a share of Series 2 Junior Preferred Stock held.

             (ii) Upon the vesting of such right of the holders of the Preferred
Stock, the maximum authorized number of members of the Board of Directors of the
Corporation shall automatically be increased by two and the two vacancies so
created shall be filled by vote of the holders of the outstanding Preferred
Stock as hereinafter




set forth. A special meeting of the shareholders of the Corporation then
entitled to vote shall be called by the Chairman or the President or the
Secretary of the Corporation, if requested in writing by the holders of record
of not less than 10% of the Preferred Stock then outstanding. At such special
meeting, or, if no such special meeting shall have been called, then at the next
annual meeting of shareholders of the Corporation, the holders of the shares of
the Preferred Stock shall elect, voting as above provided, two directors of the
Corporation to fill the aforesaid vacancies created by the automatic increase in
the number of members of the Board of Directors of the Corporation. The term of
office of the two directors so elected shall end on the date of the annual
meeting following such election. At any and all such meetings for such election,
the holders of a majority of the outstanding shares of the Preferred Stock shall
be necessary to constitute a quorum for such election, whether present in person
or by proxy, and such two directors shall be elected by the vote of at least a
plurality of shares held by such shareholders present or represented at the
meeting. Any director elected by holders of shares of the Preferred Stock
pursuant to this Section may be removed at any annual or special meeting, by
vote of a majority of the shareholders voting as a class who elected such
director, with or without cause. In case any vacancy shall occur among the
directors elected by the holders of the Preferred Stock pursuant to this
Section, such vacancy may be filled by the remaining director so elected, or his
successor then in office, and the director so elected to fill such vacancy shall
serve until the next meeting of shareholders for the election of directors.
After the holders of the Preferred Stock shall have exercised their right to
elect directors in any default period and during the continuance of such period,
the number of directors shall not be further increased or decreased except by
vote of the holders of Preferred Stock as herein provided or pursuant to the
rights of any equity securities ranking senior to or pari passu with the
Preferred Stock.

             (iii) The right of the holders of the Preferred Stock, voting
separately as a class, to elect two members of the Board of Directors of the
Corporation as aforesaid shall continue until, and only until, such time as all
arrears in dividends (whether or not declared) on the Preferred Stock shall have
been paid or declared and set apart for payment, at which time such right shall
terminate, except as herein or by law expressly provided, subject to revesting
in the event of each and every subsequent default of the character
above-mentioned. Upon any termination of the right of the holders of the shares
of the Preferred Stock as a class to vote for directors as herein provided, the
term of office of all directors then in office elected by the holders of
Preferred Stock pursuant to this Section shall terminate immediately. Whenever
the term of office of the directors elected by the holders of the Preferred
Stock pursuant to this Section shall terminate and the special voting powers
vested in the holders of the Preferred Stock pursuant to this Section shall have
expired, the maximum number of members of the Board of Directors of the
Corporation shall be such number as may be provided for in the By-laws of the
Corporation irrespective of any increase made pursuant to the provisions of this
Section.

         (D) Except as set forth herein or in the Restated Certificate of
Incorporation, as amended from time to time, holders of Series 2 Junior
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 and other capital
stock of the Corporation 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 2 Junior Preferred Stock as provided in Section 2 hereof
are in arrears, hereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on shares of Series 2 Junior Preferred
Stock outstanding shall have been paid in full, the Corporation shall not:

            (i) declare or pay dividends on, make any other distributions on, or
redeem or purchase or otherwise acquire for consideration any shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series 2 Junior Preferred Stock;

            (ii) declare or pay dividends on 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 2 Junior Preferred
Stock, except dividends paid ratably on the Series 2 Junior 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 on a parity (either as to dividends or upon
liquidation, dissolution or winding up) with the Series 2 Junior Preferred
Stock, provided that the Corporation may at any time redeem, purchase or
otherwise acquire shares of any such parity 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 2 Junior Preferred Stock;
or

            (iv) purchase or otherwise acquire for consideration any shares of
Series 2 Junior 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 direct or indirect 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, purchase or otherwise acquire such shares at such time and in such
manner.

         Section 5. Reacquired Shares. Any shares of Series 2 Junior 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 and in the Restated
Certificate of Incorporation of the Corporation, as amended from time to time.

         Section 6. Liquidation, Dissolution or Winding Up. (A) Upon any
voluntary liquidation, dissolution or winding up of the Corporation, no
distribution shall be made to the holders of shares of stock ranking junior
(either as to dividends or upon liquidation, dissolution or winding up) to the
Series 2 Junior Preferred Stock unless, prior thereto, the holders of shares of
Series 2 Junior Preferred Stock shall have received $.01 per share, plus an
amount equal to accrued and unpaid dividends and distributions thereon, whether
or not declared, to the date of such payment (the "Series 2 Liquidation
Preference"). Following the payment of the full amount of the Series 2
Liquidation Preference, no additional distributions shall be made to the holders
of shares of Series 2 Junior Preferred Stock unless, prior thereto, the holders
of shares of Common Stock shall have received an amount per share (the "Common
Adjustment") equal to the quotient obtained by dividing (i) the Series 2
Liquidation Preference by (ii) 1,000 (as appropriately adjusted as set forth in
subparagraph C below to reflect such events as stock splits, stock dividends and
recapitalizations with respect to the Common Stock) (such number in clause (ii),
the "Adjustment Number"). Following the payment of the full amount of the Series
2 Liquidation Preference and the Common Adjustment in respect of all outstanding
shares of Series 2 Junior Preferred Stock and Common Stock, respectively,
holders of Series 2 Junior Preferred Stock and holders of shares of Common Stock
shall receive their ratable and proportionate share of the remaining assets to
be distributed in the ratio, on a per share basis, of the Adjustment Number to
one with respect to such Preferred Stock and Common Stock, on a per share basis,
respectively.

         (B) If, however, there are not sufficient assets available to permit
payment in full of the Series 2 Liquidation Preference and the liquidation
preferences of all other series of Preferred Stock, if any, which rank on a
parity with the Series 2 Junior Preferred Stock, then such remaining assets
shall be distributed ratably to the holders of such parity shares in proportion
to their respective liquidation preferences.

         (C) If the Corporation shall at any time following July 24,1998 (i)
declare any dividend on Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding shares of Common Stock or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the Adjustment Number in effect immediately prior to such event shall be
adjusted by multiplying such Adjustment 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.




         Section 7. Consolidation. Merger, etc. If 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 the shares of
Series 2 Junior Preferred Stock shall at the same time be similarly exchanged or
changed in 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.
If the Corporation shall at any time (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 amount set forth in the preceding sentence with
respect to the exchange or change of shares of Series 2 Junior Preferred Stock
shall be adjusted by multiplying such amount by a fraction the numerator of
which is the number or 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 8. Redemption. The shares of Series 2 Junior Preferred Stock
shall not be redeemable by the Corporation. The preceding sentence shall not
limit the ability of the Corporation to purchase or otherwise deal in such
shares of stock to the extent permitted.

         Section 9. Ranking. The Series 2 Junior Preferred Stock shall rank
junior to all other series of the Corporation's preferred stock (whether with or
without par value) as to the payment of dividends and the distribution of
assets, unless the terms of any such series shall provide otherwise.

         Section 10. Amendment. The Restated Certificate of Incorporation of the
Corporation shall not be amended in any manner which would materially alter or
change the powers, preferences or special rights of the Series 2 Junior
Preferred Stock so as to affect them adversely without the affirmative vote of
the holders of two-thirds or more of the outstanding shares of Series 2 Junior
Preferred Stock, voting separately as a class.

         Section 11. Fractional Shares. Series 2 Junior Preferred Stock may be
issued in fractions of a share which shall entitle the holder, in proportion to
such holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of Series 2 Junior Preferred Stock.

         7. The amendments to the Certificate of Incorporation of the
Corporation set forth in paragraphs 3, 4, 5 and 6 of this Certificate were
authorized by the Board of Directors of the Corporation at a meeting of the
Board of Directors duly held on July 24,1998 pursuant to authority vested in the
Board of Directors by the Certificate of Incorporation of the Corporation.
