                                   DIVISION A

                   EXPRESS TERMS OF THE SERIAL PREFERRED STOCK

    Section 1. The Serial Preferred Stock may be issued from time to time in one
or more series. All shares of Serial Preferred Stock shall be of equal rank and
shall be identical, except in respect of the matters that may be fixed by the
Board of Directors as hereinafter provided, and each share of each series shall
be identical with all other shares of such series, except as to the date from
which dividends are cumulative. Subject to the provisions of Section 2 to 8,
both inclusive, of this Division A, which provisions shall apply to all Serial
Preferred Stock, the Board of Directors hereby is authorized to cause such
shares to be issued in one or more series, and with respect to each such series,
prior to the issuance thereof, to fix:

       (a) The designation of the series which may be by distinguishing number, 
    letter or title.

       (b) The number of shares of the series, which number the Board of 
    Directors may (except where otherwise provided in the creation of the 
    series) increase or decrease (but not below the number of shares thereof 
    then outstanding).

       (c) The annual dividend rate of the series.

    

                                      2
   3

       (d) The dates at which dividends, if declared, shall be payable, and the
    dates from which dividends shall be cumulative.

       (e) The redemption rights and price or prices, if any, for shares of the
    series.

       (f) The terms and amount of any sinking fund provided for the purchase or
    redemption of shares of the series.

       (g) The amounts payable on shares of the series in the event of any
    voluntary or involuntary liquidation, dissolution or winding up of the
    affairs of the Corporation.

       (h) Whether the shares of the series shall be convertible into Common
    Stock, and, if so, the conversion price or prices, any adjustments thereof,
    and all other terms and conditions upon which such conversion may be made.

       (i) Restrictions (in addition to those set forth in Section 6(b) and 6(c)
    of this Division) on the issuance of shares of the same series or of any
    other class or series.

    The Board of Directors is authorized to adopt from time to time amendments
to the Articles of Incorporation fixing, with respect to each such series, the
matters described in clauses (a) to (i), both inclusive, of this Section 1.

    Section 2. The holders of Serial Preferred Stock of each series, in
preference to the holders of Common Stock and of any other class of shares
ranking junior to the Serial Preferred Stock, shall be entitled to receive out
of any funds legally available and when and as declared by the Board of
Directors dividends in cash at the rate for such series fixed in accordance with
the provisions of Section 1 of this Division and no more, payable quarterly on
the dates fixed for such series. Such dividends shall be cumulative, in the case
of shares of each particular series, from and after the date or dates fixed with
respect to such series. No dividends may be paid upon or declared or set apart
for any of the Serial Preferred Stock for any quarterly dividend period unless
at the same time a like proportionate dividend for the same quarterly dividend
period, ratably in proportion to the respective annual dividend rates fixed
therefor, shall be paid upon or declared or set apart for all Serial Preferred
Stock of all series then issued and outstanding and entitled to receive such
dividend.

    Section 3. In no event so long as any Serial Preferred Stock shall be
outstanding shall any dividends, except a dividend payable in Common Stock or
other shares ranking junior to the Serial Preferred Stock, be paid or declared
or any distribution be made except as aforesaid on the Common Stock or any other
shares ranking junior to the Serial Preferred Stock, nor shall any Common Stock
or any other shares ranking junior to the Serial Preferred Stock be purchased,
retired, or otherwise acquired by the Corporation (except out of the proceeds of
the sale of Common Stock or other shares ranking junior to the Serial Preferred
Stock received by the Corporation subsequent to March 31, 1968):

       (a) Unless all accrued and unpaid dividends on Serial Preferred Stock,
    including the full dividends for the current quarterly dividend period,
    shall have been declared and paid or a sum sufficient for payment thereof
    set apart; and

       (b) Unless there shall be no arrearages with respect to the redemption of
    Serial Preferred Stock of any series from any sinking fund provided for
    shares of such series in accordance with the provisions of Section 1 of this
    Division.

       

                                      3
   4

    Section 4. (a) Subject to the express terms of each series and to the
provisions of Section 6(b) (iii) of this Division, the Corporation may from time
to time redeem all or any part of the Serial Preferred Stock of any series at
the time outstanding (i) at the option of the Board of Directors at the
applicable redemption price for such series fixed in accordance with the
provisions of Section 1 of this Division, or (ii) in fulfillment of the
requirements of any sinking fund provided for shares of such series at the
applicable sinking fund redemption price, fixed in accordance with the
provisions of Section 1 of this Division, together in each case with an amount
equal to all dividends accrued and unpaid thereon (whether or not such dividends
shall have been earned or declared) to the redemption date.

    (b) Notice of every such redemption shall be mailed, postage prepaid, to the
holders of record of the Serial Preferred Stock to be redeemed at their
respective addresses then appearing on the books of the Corporation, not less
than 30 days nor more than 60 days prior to the date fixed for such redemption.
At any time before or after notice has been given as above provided, the
Corporation may deposit the aggregate redemption price of the shares of Serial
Preferred Stock to be redeemed, together with accrued and unpaid dividends
thereon to the redemption date, with any bank or trust company in Cleveland,
Ohio, or New York, New York, having capital and surplus of more than $5,000,000,
named in such notice, and direct that such deposited amount be paid to the
respective holders of the shares of Serial Preferred Stock so to be redeemed,
upon surrender of the stock certificate or certificates held by such holders.
Upon the giving of such notice and the making of such deposit, such holders
shall cease to be shareholders with respect to such shares and shall have no
interest in or claim against the Corporation with respect to such shares except
only to receive such money from such bank or trust company without interest or
the right to exercise any unexpired privileges of conversion. In case less than
all of the outstanding shares of Serial Preferred Stock are to be redeemed, the
Corporation shall select pro rata or by lot the shares so to be redeemed in such
manner as shall be prescribed by its Board of Directors.

    If the holders of shares of Serial Preferred Stock which shall have been
called for redemption shall not, within six years after such deposit, claim the
amount deposited for the redemption thereof, any such bank or trust company
shall, upon demand, pay over to the Corporation such unclaimed amounts and
thereupon such bank or trust company and the Corporation shall be relieved of
all responsibility in respect thereof and to such holders.

    (c) Any shares of Serial Preferred Stock which are redeemed by the
Corporation pursuant to the provisions of this Section 4 and any shares of
Serial Preferred Stock which are purchased and delivered in satisfaction of any
sinking fund requirements provided for shares of such series and any shares of
Serial Preferred Stock which are converted in accordance with the express terms
thereof shall be cancelled and not reissued. Any shares of Serial Preferred
Stock otherwise acquired by the Corporation shall resume the status of
authorized and unissued shares of Serial Preferred Stock without serial
designation.

    Section 5. (a) The holders of Serial Preferred Stock of any series shall, in
case of voluntary or involuntary liquidation, dissolution or winding up of the
affairs of the Corporation, be entitled to receive in full out of the assets of
the Corporation, including its capital, before any amount shall be paid or
distributed among the holders of the Common Stock or any other shares ranking
junior to the Serial Preferred Stock, the amounts fixed with respect to shares
of such series in accordance with Section 1 of this Division plus in any such
event an amount equal to all


                                      4
   5

dividends accrued and unpaid thereon (whether or not such dividends shall have
been earned or declared) to the date of payment of the amount due pursuant to
such liquidation, dissolution or winding up of the affairs of the Corporation.
In case the net assets of the Corporation legally available therefor are
insufficient to permit the payment upon all outstanding shares of Serial
Preferred Stock of the full preferential amount to which they are respectively
entitled, then such net assets shall be distributed ratably upon outstanding
shares of Serial Preferred Stock in proportion to the full preferential amount
to which each such share is entitled.

    After payment to holders of Serial Preferred Stock of the full preferential
amounts as aforesaid, holders of Serial Preferred Stock as such have no right or
claim to any of the remaining assets of the Corporation.

    (b) The merger or consolidation of the Corporation into or with any other
corporation, or the merger of any other corporation into it, or the sale, lease
or conveyance of all or substantially all the property or business of the
Corporation, shall not be deemed to be a dissolution, liquidation or winding up,
voluntary or involuntary, for the purposes of this Section 5.

    Section 6. (a) The holders of Serial Preferred Stock shall be entitled to
one vote for each share of such stock upon all matters presented to the
shareholders; and, except as otherwise provided herein or required by law, the
holders of Serial Preferred Stock and the holders of Common Stock shall vote
together as one class on all matters. No adjustment of the voting rights of the
holders of Serial Preferred Stock shall be made in the event of an increase or
decrease in the number of shares of Common Stock authorized or issued or in the
event of a stock split or combination of the Common Stock or in the event of a
stock dividend on any class of stock payable solely in Common Stock.

    If, and so often as, the Corporation shall be in default in the payment of
dividends in an amount equivalent to six quarterly dividends (whether or not
consecutive) on any series of Serial Preferred Stock at the time outstanding,
whether or not earned or declared, the holders of Serial Preferred Stock of all
series, voting separately as a class and in addition to all other rights to vote
for directors, shall thereafter be entitled to elect, as herein provided, two
members of the Board of Directors of the Corporation who shall serve, except as
hereinbelow provided, until the next annual meeting of the shareholders and
until their successors have been elected and qualified; provided, however, that
the holders of shares of Serial Preferred Stock shall not have or exercise such
special class voting rights except at meetings of the shareholders for the
election of directors at which the holders of not less than 35% of the
outstanding shares of Serial Preferred Stock of all series then outstanding are
present in person or by proxy; and provided further that the special class
voting rights provided for herein when the same shall have become vested shall
remain so vested until all accrued and unpaid dividends on the Serial Preferred
Stock of all series then outstanding shall have been paid, whereupon the holders
of Serial Preferred Stock shall be divested of their special class voting rights
in respect of subsequent elections of directors and the terms of the directors
elected by the holders of the Serial Preferred Stock shall automatically
terminate, subject to the revesting of such special class voting rights in the
event hereinabove specified in this paragraph.

    In the event of default entitling the holders of Serial Preferred Stock to
elect two directors as above specified, a special meeting of the shareholders
for the purpose of electing such


                                      5
   6

directors shall be called by the Secretary of the Corporation upon written
request of, or may be called by, the holders of record of at least 10% of the
shares of Serial Preferred Stock of all series at the time outstanding, and
notice thereof shall be given in the same manner as that required for the annual
meeting of shareholders; provided, however, that the Corporation shall not be
required, and the holders of Serial Preferred Stock shall not be entitled, to
call such special meeting if the annual meeting of shareholders shall be held
within 90 days after the date of receipt of the foregoing written request from
the holders of Serial Preferred Stock. At any meeting at which the holders of
Serial Preferred Stock shall be entitled to elect directors, the holders of 35%
of the then outstanding shares of Serial Preferred Stock of all series, present
in person or by proxy, shall be sufficient to constitute a quorum, and the vote
of the holders of a majority of such shares so present at any such meeting at
which there shall be such a quorum shall be sufficient to elect the members of
the Board of Directors which the holders of Serial Preferred Stock are entitled
to elect as hereinabove provided. If at any such meeting there shall be less
than a quorum present, the holders of a majority of the shares so present may
adjourn the meeting from time to time without notice other than announcement at
the meeting until a quorum shall attend.

    The two directors who may be elected by the holders of Serial Preferred
Stock pursuant to the foregoing provisions shall be in addition to any other
directors then in office or proposed to be elected otherwise than pursuant to
such provisions, and nothing in such provisions shall prevent any change
otherwise permitted in the total number of directors of the Corporation or
require the resignation of any director elected otherwise than pursuant to such
provisions.

    (b) The affirmative vote or consent of the holders of at least two-thirds of
the shares of Serial Preferred Stock at the time outstanding, given in person or
by proxy either in writing or at a meeting called for the purpose at which the
holders of Serial Preferred Stock shall vote separately as a class, shall be
necessary to effect any one or more of the following (but so far as the holders
of Serial Preferred Stock are concerned, such action may be effected with such
vote or consent):

       (i) Any amendment, alteration or repeal of any of the provisions of the
    Articles of Incorporation or of the Regulations of the Corporation which
    affects adversely the voting powers, rights or preferences of the holders of
    Serial Preferred Stock; provided, however, that, for the purpose of this
    clause (i) only, neither the amendment of the Articles of Incorporation so
    as to authorize or create, or to increase the authorized or outstanding
    amount of, Serial Preferred Stock or of any shares of any class ranking on a
    parity with or junior to the Serial Preferred Stock, nor the amendment of
    the provisions of the Regulations so as to increase the number of directors
    of the Corporation, shall be deemed to affect adversely the voting powers,
    rights or preferences of the holders of Serial Preferred Stock; and provided
    further, that if such amendment, alteration or repeal affects adversely the
    rights or preferences of one or more but not all series of Serial Preferred
    Stock at the time outstanding, only the vote or consent of the holders of at
    least two-thirds of the number of the shares at the time outstanding of the
    series so affected shall be required; or

       (ii) The authorization or creation of, or the increase in the authorized
    amount of, any shares of any class, or any security convertible into shares
    of any class, ranking prior to the Serial Preferred Stock; or

       

                                      6
   7

       (iii) The purchase or redemption (for sinking fund purposes or otherwise)
    of less than all of the Serial Preferred Stock then outstanding except in
    accordance with a stock purchase offer made to all holders of record of
    Serial Preferred Stock, unless all dividends upon all Serial Preferred Stock
    then outstanding for all previous quarterly dividend periods shall have been
    declared and paid or funds therefor set apart and all accrued sinking fund
    obligations applicable thereto shall have been complied with.

    (c) The affirmative vote or consent of the holders of at least a majority of
the shares of Serial Preferred Stock at the time outstanding, given in person or
by proxy in writing or at a meeting called for the purpose at which the holders
of Serial Preferred Stock shall vote separately as a class, shall be necessary
to effect any one or more of the following (but so far as the holders of Serial
Preferred Stock are concerned, such action may be effected with such vote or
consent):

       (i) The consolidation of the Corporation with or its merger into any
    other corporation unless the corporation resulting from such consolidation
    or merger will have after such consolidation or merger no class of shares
    either authorized or outstanding ranking prior to or on a parity with the
    Serial Preferred Stock except the same number of shares ranking prior to or
    on a parity with the Serial Preferred Stock and having the same rights and
    preferences as the shares of the Corporation authorized and outstanding
    immediately preceding such consolidation or merger, and each holder of
    Serial Preferred Stock immediately preceding such consolidation or merger
    shall receive the same number of shares, with the same rights and
    preferences of the resulting corporation; or

       (ii) The authorization of any shares ranking on a parity with the Serial
    Preferred Stock or an increase in the authorized number of shares of Serial
    Preferred Stock; or

       (iii) The sale, lease or conveyance by the Corporation of all or
    substantially all of its property or business.

    Section 7. If the shares of any series of Serial Preferred Stock shall be
convertible into Common Stock, then upon conversion of shares of such series the
stated capital of the Common Stock issued upon such conversion shall be the
aggregate par value of the shares so issued having par value, or, in the case of
shares without par value, shall be an amount equal to the stated capital
represented by each share of Common Stock outstanding at the time of such
conversion multiplied by the number of shares of Common Stock issued upon such
conversion. The stated capital of the Corporation shall be correspondingly
increased or reduced to reflect the difference between the stated capital of the
shares of Serial Preferred Stock so converted and the stated capital of the
Common Stock issued upon such conversion.

    Section 8. For the purpose of this Division A:

    Whenever reference is made to shares "ranking prior to the Serial Preferred
Stock", such reference shall mean and include all shares of the Corporation in
respect of which the rights of the holders thereof as to the payment of
dividends or as to distributions in the event of an involuntary liquidation,
dissolution or winding up of the Corporation are given preference over the
rights of the holders of Serial Preferred Stock; whenever reference is made to
shares "on a parity with the Serial Preferred Stock", such reference shall mean
and include all shares of the Corporation in respect of which the rights of the
holders thereof as to the payment of dividends



                                      7
   8

and as to distributions in the event of an involuntary liquidation, dissolution
or winding up of the Corporation rank on an equity (except as to the amounts
fixed therefor) with the rights of the holders of Serial Preferred Stock; and
whenever reference is made to shares "ranking junior to the Serial Preferred
Stock" such reference shall mean and include all shares of the Corporation in
respect of which the rights of the holders as to the payment of dividends and as
to distributions in the event of an involuntary liquidation, dissolution or
winding up of the Corporation are junior and subordinate to the rights of the
holders of the Serial Preferred Stock.

                                  DIVISION A-I
                        SERIAL PREFERRED STOCK, SERIES A 

    Section 1. There is established hereby a series of Serial Preferred Stock
that shall be designated "Serial Preferred Stock, Series A" (hereinafter
sometimes called this "Series" or the "Series A Preferred Shares") and that
shall have the terms set forth in this Division A-1.

    Section 2. The number of shares of this Series shall be 450,000.

    Section 3. (a) The holders of record of Series A Preferred Shares shall be
entitled to receive, when and as declared by the Board of Directors in
accordance with the terms hereof, out of funds legally available for the
purpose, cumulative quarterly dividends payable in cash on the first day of
January, April, July and October 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 Series A Preferred
Share or fraction of a Series A Preferred Share in an amount per share (rounded
to the nearest cent) equal to the lesser of (i) $1.50 or (ii) subject to the
provision for adjustment hereinafter set forth, 100 times the aggregate per
share amount of all cash dividends, and 100 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
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 Series A Preferred Share or fraction of a Series A Preferred Share. In
the event the Corporation shall at any time declare or pay any dividend on the
Common Stock payable in 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 Common Stock) into a greater or
lesser number of shares of Common Stock, then in each such case the amount to
which holders of Series A Preferred Shares were entitled immediately prior to
such event under clause (ii) 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) Dividends shall begin to accrue and be cumulative on outstanding Series
A Preferred Shares from the Quarterly Dividend Payment Date next preceding the
date of issue of such Series A Preferred 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



                                      8
   9

Series A Preferred Shares 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. No dividends shall
be paid upon or declared and set apart for any Series A Preferred Shares for any
dividend period unless at the same time a dividend for the same dividend period,
ratably in proportion to the respective annual dividend rates fixed therefor,
shall be paid upon or declared and set apart for all Serial Preferred Stock of
all series then outstanding and entitled to receive such dividend. The Board of
Directors may fix a record date for the determination of holders of Series A
Preferred Shares entitled to receive payment of a dividend or distribution
declared thereon, which record date shall be no more than 40 days prior to the
date fixed for the payment thereof.

    Section 4. Subject to the provisions of Section 6(b)(iii) of Division A and
in accordance with Section 4 of Division A, the Series A Preferred Shares shall
be redeemable from time to time at the option of the Board of Directors of the
Corporation, as a whole or in part, at any time at a redemption price per share
equal to one hundred times the then applicable Purchase Price as defined in that
certain Rights Agreement, dated as of January 26, 1988 between the Corporation
and Ameritrust Company National Association (the "Rights Agreement"), as the
same may be from time to time amended in accordance with its terms, which
Purchase Price is $100 as of January 26, 1988, subject to adjustment from time
to time as provided in the Rights Agreement. Copies of the Rights Agreement are
available from the Company upon request. In the event that fewer than all of the
outstanding Series A Preferred Shares are to be redeemed, the number of shares
to be redeemed shall be as determined by the Board of Directors and the shares
to be redeemed shall be selected pro rata or by lot in such manner as shall be
determined by the Board of Directors.

    Section 5. (a) In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the affairs of the Corporation (hereinafter
referred to as a "Liquidation"), no distribution shall be made to the holders of
shares of stock ranking junior (either as to dividends or upon Liquidation) to
the Series A Preferred Shares, unless, prior thereto, the holders of Series A
Preferred Shares shall have received at least an amount per share equal to one
hundred times the then applicable Purchase Price as defined in the Rights
Agreement, as the same may be from time to time amended in accordance with its
terms which Purchase Price is $100 as of January 26, 1988, subject to adjustment
from time to time as provided in the Rights Agreement, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not earned or
declared, to the date of such payment, provided that the holders of shares of
Series A Preferred Shares shall be entitled to receive an aggregate amount per
share, subject to the provision for adjustment hereinafter set forth, equal to
100 times the aggregate amount to be distributed per share to holders of Common
Stock (the "Series A Liquidation Preference").

    (b) In the event, however, that the net assets of the Corporation are not
sufficient to pay in full the amount of the Series A Liquidation Preference and
the liquidation preferences of all other series of Serial Preferred Stock, if
any, which rank on a parity with the Series A Preferred Shares as to
distribution of assets in Liquidation, all shares of this Series and of such
other Serial Preferred Stock shall share ratably in the distribution of assets
(or proceeds thereof) in Liquidation in proportion to the full amounts to which
they are respectively entitled.

dividend on the Common Stock payable in Common Stock, or effect a subdivision or
combination or consolidation of the outstanding Common Stock (by
reclassification or otherwise than by payment of a dividend in Common Stock)
into a greater or lesser number of shares of Common Stock, then in each such
case the amount to which holders of Series A Preferred Shares were entitled
immediately prior to such event pursuant to the proviso set forth in paragraph
(a) above, 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.

    (d) The merger or consolidation of the Corporation into or with any other

    release of the holders of shares entitling them to exercise two-thirds, or
    any other proportion, of the voting power of the Corporation or of any class
    or classes of shares thereof, such action, unless otherwise expressly
    required by statute or by the Articles of the Corporation, may be taken by
