     X. INDEMNIFICATION.  The Corporation shall indemnify, to the fullest extent
     now or  hereafter  permitted  by  law,  each  director  or  officer  of the
     Corporation or its  Subsidiaries who is made a party or is threatened to be
     made a party to any  threatened,  pending,  or  completed  action,  suit or
     proceeding,  whether civil, criminal,  administrative or investigative,  by
     reason of the fact that he is or was an  authorized  representative  of the
     Corporation,   against  all  expenses   (including   attorney's   fees  and
     disbursements), judgments, fines (including excise taxes and penalties) and
     amounts  paid in  settlement  actually  and  reasonably  incurred by him in
     connection  with  such  action,  suit or  proceeding.  Expenses  (including

     be paid by the  Corporation  in  advance of the final  disposition  of such
     action,   suit  or  proceeding,   to  the  fullest  extent  and  under  the
     circumstances  permitted by Delaware law. The  Corporation may purchase and
     maintain  insurance  on  behalf  of any  person  who is or was a  director,
     officer,   employee,   fiduciary,  or  agent  of  the  Corporation  or  its
     Subsidiaries  against any liability  asserted  against and incurred by such
     person in any such  capacity  or  arising  out of such  person's  position,
     whether or not the  Corporation  would have the power to indemnify  against
     such  liability  under the  provisions  of this  Article  VII.  The  rights
     conferred  by this  Article  shall not be  exclusive of any other rights to
     which  those   indemnified  may  be  entitled  under  this  Certificate  of
     Incorporation, any by-law, agreement, vote of stockholders or disinterested
     directors,  statute, or otherwise,  and shall inure to the benefit of their
     heirs, executors, and administrators.  The provisions of this Article shall
     not be deemed to preclude the Corporation from  indemnifying  other persons
     from similar or other expenses and liabilities as the Board of Directors or
     the stockholders  may determine in a specific  instance or by resolution of
     general  application.  Any repeal or  modification  of this  Article by the
     stockholders  of the  Corporation  shall not adversely  affect any right or
     protection existing at the time of such repeal or modification to which any
     person  may be  entitled  under  this  Article.  For the  purposes  of this
     Article,  the term  "authorized  representative"  shall mean a director  or
     officer of the Corporation or

                                      - 2 -





     of any  subsidiary  of the  Corporation  or  person  who is or was,  at the
     request of the Corporation, serving another corporation, partnership, joint
     venture,  trust,  association,  or other entity as a director,  officer, or
     partner, or in any position of similar managerial or fiduciary position, or
     as an employee or agent.

     XI. LIABILITY. A director of the Corporation shall not be personally liable
     to the Corporation or its  stockholders  for monetary damages for breach of
     fiduciary duty as a director,  provided, however, that this provision shall
     not limit liability (i) for any breach of the director's duty of loyalty to
     the Corporation or its stockholders, (ii) for acts or omissions not in good
     faith or which involve  intentional  misconduct  or a knowing  violation of
     law,  (iii)  for  violations  of  Section  174  of  the  Delaware   General
     Corporation  Law,  or (iv) for any  transaction  from  which  the  director
     derived any improper personal benefit.  If the Delaware General Corporation
     Law  hereafter is amended to further  eliminate or limit the liability of a
     director,  then  a  director  of  the  Corporation,   in  addition  to  the
     circumstances in which a director is not personally  liable as set forth in
     the preceding sentence, shall not be liable to the fullest extent permitted
     by the amended Delaware General Corporation Law. Any repeal or modification
     of this  Article  VIII by the  stockholders  of the  Corporation  shall not
     adversely  affect any right or protection of a director of the  Corporation
     existing at the time of such repeal or modification.

     XII.   TRANSACTIONS  WITH  DIRECTORS,   ETC.  The  Corporation  shall  have
     authority,  to the fullest extent now or hereafter permitted by the General
     Corporation Law of the State of Delaware,  or by any other  applicable law,
     to enter into any contract or transaction with one or more of its directors
     or officers, or with any corporation,  partnership,  joint venture,  trust,
     association,  or other  entity  in which  one or more of its  directors  or
     officers  are  directors  or  officers,   or  have  a  financial  interest,
     notwithstanding  such relationships and  notwithstanding  the fact that the
     director  or officer is present at or  participates  in the  meeting of the
     board of directors or committee  thereof which  authorizes  the contract or
     transaction.

     XIII.  COMPROMISE OR  ARRANGEMENT.  Whenever a compromise or arrangement is
     proposed  between this  Corporation  and its creditors or any class of them
     and/or between this  Corporation and its stockholders or any class of them,
     any court of equitable  jurisdiction  within the State of Delaware  may, on
     the application in a summary way of this  Corporation or of any creditor or
     stockholder  thereof or on the  application  of any  receiver or  receivers
     appointed for this Corporation under the provisions of Section 291 of Title
     8 of the Delaware Code or on the  application of trustees in dissolution or
     of any  receiver or  receivers  appointed  for this  Corporation  under the
     provisions  of Section 279 of Title 8 of the Delaware  Code order a meeting
     of the creditors or class of creditors, and/or of the stockholders or class
     of stockholders of this Corporation,  as the case may be, to be summoned in
     such manner as the said court directs. If a majority in number representing
     three-fourths  in value of the creditors or class of creditors,  and of the
     stockholders or class of stockholders of this Corporation,  as the case may
     be, agree to any

                                      - 3 -





     compromise or arrangement and to any  reorganization of this Corporation as
     a consequence of such  compromise or  arrangement,  the said  compromise or
     arrangement and the said  reorganization  shall, if sanctioned by the court
     to which  the  said  application  has  been  made,  be  binding  on all the
     creditors or class of creditors, and/or on all the stockholders or class of
     stockholders,  of this  Corporation,  as the case may be,  and also on this
     Corporation.

     XIV. SECTION 203. The Corporation shall not be subject to the provisions of
     Section 203 of the Delaware General Corporation Law.

     SECOND: That no stock of the Corporation has been issued.

     IN  WITNESS  WHEREOF,  the  Corporation  has  caused  this  Certificate  of
Amendment to be signed by Albert M. Holtz, its Chairman.

                      Common;

Class A Common into the percentage of total  outstanding Class B Common equal to
AP) than the  consideration  received  with  respect to or in  exchange  for the
shares of Class B Common or would otherwise be treated  differently  from shares
of  Class  B  Common   (assuming  such   conversion)  in  connection  with  such

exclusion  of  holders  of any  preferred  stock,  bonds,  debentures,  or other
obligations of the Corporation.

another entity or entities, or any recapitalization or reorganization,  in which
shares  of  Class B Common  would  receive  or be  exchanged  for  consideration
different on a per share basis than the  consideration  received with respect to

Class A common into the  percentage of the  outstanding  shares of total Class B
Common equal to AP) or would otherwise be treated differently from shares of the

         2.  DIVIDENDS.  Subject  to the  preference  rights of the  holders  of

                                      - 3 -





                 1. DIVIDENDS.

                      A. GENERAL OBLIGATION.  The holders of the 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  therefor,  preferential
dividends  on each share of the  Preferred  Stock (a "Share") at the rate of 12%
per annum of the Liquidation  Preference  thereof from and including the date of
issuance  of such  Share to and  including  the date on  which  the  Liquidation
Preference of such Share is paid (the  "Dividend  Preference").  Such  dividends
will  accrue  cumulatively  on an  annual  basis  whether  or not they have been
declared  and  whether or not there are  profits,  surplus or other funds of the
Corporation  legally  available for the payment of dividends.  Such preferential
dividends shall be payable upon the  liquidation,  dissolution and winding up of
the  Corporation in each case when and as declared by the Board of Directors and
to the extent  permitted  by  Delaware  law.  The date on which the  Corporation
initially  issues  any  Share  will  be  deemed  to be its  "date  of  issuance"
regardless  of the number of times  transfer  of such Share is made on the stock
records  maintained by or for the  Corporation  and  regardless of the number of
certificates which may be issued to evidence such Share. No dividends in cash or
property  (other than dividends  payable to the holders of the Class A Common or
Class B Common in  shares  of Class A Common or Class B Common)  will be paid on
Junior Securities unless all of the Dividend Preference accrued on the Preferred
Stock have been paid.  Following  satisfaction of the Dividend  Preference,  the
holders of the Preferred Stock shall be entitled to no additional dividends.

                      B.  DIVIDEND  REFERENCE  DATES.  To the extent not paid on
each  December 31 (the  "Dividend  Reference  Date"),  beginning on December 31,
1993, all of the Dividend Preference  dividends which have accrued on each Share
outstanding  during the twelve-month  period (or other period in the case of the
initial Dividend  Reference Date) ending upon each such Dividend  Reference Date
will be added to the  Liquidation  Preference of such Share and will remain part
thereof until such dividends are paid.

                      C.  DISTRIBUTION OF PARTIAL DIVIDEND  PAYMENTS.  If at any
time the Corporation  pays to the holders of Preferred Stock less than the total
amount of the  Dividend  Preference  dividends  then accrued with respect to the
Preferred Stock,  such payment will be distributed  ratably among the holders of
such  Preferred  Stock  based upon the  aggregate  accrued  but unpaid  Dividend
Preference on the shares of Preferred Stock hold by each such holder.

         2. VOTING  RIGHTS.  Except as otherwise  required by law, the Preferred
Stock shall have no voting rights.

         3. LIQUIDATION. Upon any liquidation,  dissolution or winding up of the
Corporation,  whether  voluntary or involuntary,  the holders of Preferred Stock
will be entitled to be paid, before any distribution or payment is made upon any
Junior  Securities,  an  amount  in  cash  equal  to the  aggregate  Liquidation
Preference of all Shares outstanding. If upon any such

                                      - 4 -





liquidation,  dissolution or winding up of the  Corporation,  the  Corporation's
assets  to  be  distributed  among  the  holders  of  the  Preferred  Stock  are
insufficient  to permit  payment to such holders of the  Liquidation  Preference
amount  which  they are  entitled  to be  paid,  then the  entire  assets  to be
distributed to Preferred  Stock will be  distributed  ratably among such holders
based  upon the  aggregate  Liquidation  Preference  (plus  declared  and unpaid
dividends)  of the  Preferred  Stock held by each of such  holders.  Neither the
consolidation or merger of the Corporation into or with any other corporation or
corporations,  nor the sale or transfer by the Corporation of all or any part of
its assets,  nor the reduction of the Capital Stock of the Corporation,  will be
deemed to be a liquidation,  dissolution or winding up of the Corporation within
the meaning of this paragraph IV(D) (3).

     E.  REGISTRATION  OF TRANSFER The  Corporation  will keep at its  principal
office a register for the  registration of each of its classes of Capital Stock.
Upon the surrender of any  certificate  representing  any class of stock at such
place,  the  Corporation  will,  at the  request  of the  record  holder of such
certificate,   execute  and  deliver  (at  the  Corporation's  expense),  a  new
certificate or certificates in exchange  therefor  representing in the aggregate
the number of shares represented by the surrendered  certificate.  Each such new
certificate  will be registered in such name and will  represent  such number of
shares as is requested by the holder of the surrendered  certificate and will be
substantially  identical  in  form to the  surrendered  certificate,  and,  with
respect to the Preferred  Stock,  dividends will continue to accrue on Preferred
Stock  represented by such new certificate from the date to which dividends have
previously  been paid on such Preferred  Stock  represented  by the  surrendered
Certificate.

     F.  REPLACEMENT.  Upon receipt of evidence  reasonably  satisfactory to the
Corporation (an affidavit of the registered  holder will be satisfactory) of the
ownership and the loss,  theft,  destruction  or  mutilation of any  certificate
evidencing  shares of any class of  Capital  Stock,  and in the case of any such
loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to
the Corporation  (provided that if the holder is an  institutional  investor its
own agreement will be satisfactory), or, in the case of any such mutilation upon
surrender of such certificate, the Corporation will (at its expense) execute and
deliver in lieu of such certificate a new certificate of like kind  representing
the number of shares of such class represented by such lost,  stolen,  destroyed
or mutilated  certificate and dated the date of such lost, stolen,  destroyed or
mutilated certificate,  and, with respect to the Preferred Stock, dividends will
continue to accrue on the Preferred  Stock  represented by such new  certificate
from the date on which dividends have previously been paid on such lost, stolen,
destroyed or mutilated certificate.

     G. DEFINITIONS.

     "AP" shall have the meaning set forth in Paragraph IV (B) (1) hereof.

     "Capital  Stock" shall mean all shares of all classes of the  Corporation's
capital  stock,  and any Stock into which such  Capital  Stock may  hereafter be
