          restrictions  thereof,  of the  shares of such  series  pursuant  to a
          unanimous vote of the Board of Directors held on October 1, 1993:
               RESOLVED,  that  pursuant to authority  expressly  granted to the
          Board of Directors by the  provisions of this  Corporations'  Restated
          Certificate of  Incorporation,  the Board of Directors  hereby creates
          the  second  series  of the  Preference  Stock of the  Corporation  to
          consist initially of 200,000 shares ("Second Series") and hereby fixes
          the  designations,   preferences  and  rights,   and   qualifications,
          limitations and restrictions thereof, of the shares of such series (in
          addition  to  the  designations,   preferences  and  rights,  and  the
          qualification,  limitations and restrictions thereof, set forth in the
          Restated  Certificate  of  Incorporation  which are applicable to this
          Corporation's Preference Stock of all series) as follows:
               i.   DESIGNATION OF SERIES. The Second Series shall be designated
                    by the  Series B Senior  Redeemable  Convertible  Preference
                    Stock.
               ii.  NUMBER OF SHARES.  The number of shares of the Second Series
                    shall be  200,000,  which  number  from  time to time may be
                    increased or  decreased  (but not below the number of shares
                    in the series then  outstanding)  by resolution of the Board
                    of Directors of the Corporation.
               iii. DIVIDENDS The dividend rate of the Second Series shall be 8%
                    per  share per annum in cash,  and no more,  which  shall be
                    payable  from  funds  legally  available  foe  that  purpose
                    annually  on June 30 of each  year,  commencing  on June 30,
                    1994.  Dividends  on  shares  of  the  Second  Series  shall
                    cumulate  from the date of their  purchase,  but accruals of
                    the dividends will not bear interest.  If such dividends for
                    any quarterly period are not paid in full, holders of shares
                    of the Second  Series shall  participate  ratable,  with the
                    holders of all shares of  Preference  Stock  (excluding  the
                    shares of such series thereof,  if any, which by their terms
                    rank  junior as to  dividends  to the  shares of the  Second
                    Series),  in any cash  dividends  paid for such  period,  in
                    proportion  to the full amounts of dividends for such period
                    to which they are entitled,  and the  Corporation  shall not
                    pay cash  dividends  to the holders of shares of  Preference
                    Stock for any  subsequent  period or to holders of shares of
                    Preference  Stock of any  series  which by their  terms rank
                    junior to the  shares of the  Second  Series  until all such
                    dividends  accrued on shares of the Second  Series have been
                    paid in full.

               iv.  REDEMPTION.  Share of the Second  Series shall be redeemable
                    at the Corporation's  sole option in whole or in any part at
                    any time or times after the fifth anniversary of the date of
                    their issue, but not earlier,  at the price of $10 per share
                    plus  in  each  case  an  amount  equal  to  all   dividends
                    accumulated  but unpaid on such shares to the date fixed for
                    redemption   whether  or  not  earned  or   declared  (  the
                    "redemption price"). Notice of every redemption, stating the
                    date fixed for  redemption,  the redemption  price,  and the
                    place of payment  thereof,  shall be given by mailing a copy
                    of such  notice  no  later  than the  thirtieth  day and not
                    earlier  than the  sixtieth  day prior to the date fixed for
                    redemption  to the holders of the record of the shares to be
                    redeemed at their  addresses as the same shall appear on the
                    books of the  Corporation.  The  Corporation,  upon or after
                    mailing  notice of  redemption as aforesaid or upon or after
                    irrevocably  authorizing  the bank or trust  company  in the
                    city of Philadelphia,  Pennsylvania,  or such other place as
                    may be determined by the  Corporation's  Board of Directors,
                    an amount equal to the redemption  price of the shares to be
                    redeemed,  which  amount  shall be payable to the holders of
                    such shares upon  surrender of  certificates  therefor on or
                    after the redemption date or prior thereto if so directed by
                    the Board. Upon such deposit,  or if no such deposit is made
                    then from and after the date fixed for redemption unless the
                    Corporation   shall   default  in  making   payment  of  the
                    redemption   price  upon   surrender  of   certificates   as
                    aforesaid,  the shares called for redemption  shall cease to
                    be outstanding  and shall be deemed to have been acquired by
                    the  Corporation  and the holders  thereof shall cease to be
                    stockholders  with  respect to such shares and shall have no
                    interest in or claim against the Corporation with respect to
                    such shares  other than the right to receive the  redemption
                    price   from  such  bank  or  trust   company  or  from  the
                    Corporation,  as the case may be, without interest  thereon,
                    upon surrender of certificates  as aforesaid;  provided that
                    conversation  rights of shares called for  redemption  shall
                    terminate at the close of business on the fifth day prior to
                    the date fixed for  redemption  unless default shall be made
                    on payment of the  redemption  price.  In case any holder of
                    shares of the  Second  Series  which  have been  called  for
                    redemption  shall not,  within  six years  after the date of
                    such deposit, have claimed the amount deposited with respect
                    to the redemption thereof, such bank, or trust company, upon
                    demand,  shall pay over to the  Corporation  such  unclaimed
                    amount and shall thereupon be relieved of all responsibility
                    in  respect  thereof to such  holder,  and  thereafter  such
                    holder  shall  look  only  to the  Corporation  for  payment
                    thereof.  The Corporation  shall be entitled to any interest
                    that may be paid on funds so deposited.
               v.   LIQUIDATION  PREFERENCE.  In the  event  of a  voluntary  or
                    involuntary  liquidation,  dissolution  or winding up of the
                    Corporation,  holders of shares of the Second  Series  shall
                    have  a   liquidation   preference   over   holders  of  the
                    Corporation's  Common Stock and holders of the Corporation's
                    Series  A  Preferred  Stock.  Neither  the  merger  nor  the
                    consolidation  of the Corporation  into or any  corporation,
                    nor  any  sale,  transfer  or  lease  of all or  part of the
                    Corporation's  assets,  shall be deemed a liquidation of the
                    Corporation within the meaning of this paragraph (v).

               vi.  CONVERSION RIGHTS. Any holder of shares of the Second Series
                    may  convert  any or all of such  shares into fully paid and
                    non-assessable  shares  of Common  Stock of the  Corporation
                    (hereafter  called  "Common  Stock")  on the  terms,  at the
                    times, and in the manner hereinafter set forth.

                    a.   Shares of the  Second  Series may be  converted  at any
                         time one  hundred  and eighty  (180) days from the date
                         the shares were  purchased  into shares of Common Stock
                         at the rate of one hundred  shares of Common  Stock for
                         each  share of the First  Series,  such rate  should be
                         subject to adjustment as hereinafter  provided,  except
                         that as to any shares of such  series  which are called
                         for  redemption  pursuant to paragraph  (iv) hereof the
                         right of  conversion  shall  terminate  at the close of
                         business  on the fifth day prior to the date  fixed for
                         redemption  unless default shall be made in the payment
                         of  redemption  price.  Upon  conversion  no adjustment
                         shall be made for dividends  either on the shares being
                         converted or on the Common Stock issued thereupon.
                    b.   Any holder of shares of the Second Series who elects to
                         convert them shall surrender the  certificate  therefor
                         at the principal  office of any Transfer  Agent, or the
                         Corporation  as the case may be, for such shares,  with
                         the form of written notice endorsed on such certificate
                         of his/her  election  to  convert  them  completed.  If
                         necessary  under  the  circumstances  such  certificate
                         shall  be  endorsed  for  transfer  or  accompanied  by
                         executed  instruments  of transfer,  together with such
                         other  transfer   papers  as  the  Transfer  Agent  may
                         reasonably  require.  The  Corporation or such Transfer
                         Agent, as the case may be, may require,  as a condition
                         to  the  exercise  of  the  conversion  privilege,  the
                         payment  of  any  transfer  tax or  other  governmental
                         charge (but not any tax payable upon the issue of stock
                         deliverable  upon such  conversion) that may be imposed
                         upon   any   transfer   incidental   or  prior  to  the
                         conversion,  or the submission of proper proof that the
                         same has been paid. The conversion  privilege  shall be
                         deemed to have been exercised, and the shares of Common
                         Stock issuable upon such conversion  shall be deemed to
                         have been issued,  upon the date the Transfer Agent, or
                         the  Corporation  as the  case  may  be,  receives  for
                         conversion  the  certificate  representing  such shares
                         with  the  required  terms  for  conversion  satisfied,
                         except that as to any shares of such  series  which are
                         surrendered for conversion on a date which is less than
                         five  business  days  preceding  the date fixed for the
                         determination  of holders of Common  Stock  entitled to
                         receive  rights to subscribe for or to purchase  shares
                         of Common Stock or other  securities of the Corporation
                         convertible to Common Stock,  the conversion  privilege
                         shall be deemed to have been  exercised on the business
                         day   next   succeeding   the  date   fixed   for  such
                         determination.  Each  person  entitled  to receive  the
                         Common Stock issuable upon such  conversion  shall from
                         the same date be treated  as the record  holder of such
                         Common Stock, and the person who surrenders such shares
                         for  conversion  shall on that date cease to be treated
                         as the record holder of the shares surrendered.
                    c.   The Corporation  shall not issue in connection with the
                         conversion of share of the Second  Series  certificates

                         for a  fraction  on one share of Common  Stock,  but in
                         lieu  thereof   shall  pay  to  any  person  who  would
                         otherwise  be entitled  thereto an amount of case equal
                         to such fraction  multiplied by the Market Price of the
                         Common  Stock  on the  last  business  day of the  week
                         preceding  the week in which the  conversion  privilege
                         was  deemed to have  been  exercised.  As used  herein,
                         "Market  Price"  means  the last  reported  sale  price
                         regular  way on such day or,  in case no such  reported
                         sale takes place on such day, the reported  closing bid
                         price  regular  way,  in either  case on the  principal
                         national  securities exchange on which the Common Stock
                         is  then  listed  or,  if not  listed  on any  national
                         securities  exchange,  the  closing  bid  price  in the
                         over-the-counter  market  as  reported  by any New York
                         Stock  Exchange  member firm selected from time to time
                         by the Board of Directors for that purpose.
                    d.   As soon as  practicable  after  the  effective  date of
                         conversion  of any  shares of the  Second  Series,  the
                         Corporation  shall  deliver  to the  person or  persons
                         entitled  thereto,  at  the  principal  office  of  the
                         Transfer Agent at which such stock was  surrendered for
                         conversion,  or the  Corporation  as the  case  may be,
                         certificates  representing  the shares of Common  Stock
                         and any cash to which such  person or persons  shall be
                         entitled on such conversion.
                    e.   The conversion  rate set forth in  subparagraph  (a) of
                         this  paragraph  (vi) shall be subject to adjustment as
                         follows:

                        1.    if  the  Corporation  subdivides  the  outstanding
                              shares of its Common  Stock into a greater  number
                              of shares or combines  them into a smaller  number
                              of   shares,   the   conversion   rate  in  effect
                              immediately   prior   to   such   subdivision   or
                              combination shall be proportionately  increased or
                              decreased  effective at the opening of business on
                              the  day   following   the  day  upon  which  such
                              subdivision or combination becomes effective;
                        2.    if the  Corporation  fixes a  record  date for the
                              purpose of  determining  the  holders of shares of
                              Common Stock,  entitled to receive any dividend in
                              Common  Stock,   the  conversion  rate  in  effect
                              immediately  prior to such  record  date  shall be
                              proportionally  increased effective at the opening
                              of  business  on the day  following  such a record
                              date,  provided that if for any reason the plan to
                              pay such  dividend  in  Common  Stock  is  legally
                              abandoned before payment, that any adjustment made
                              in the conversion rate by reason of the passage of
                              such record date shall be cancelled as of the date
                              the plan is abandoned;
                        3.    the  insurance  to all holders of Common  Stock of
                              the  corporation  of rights to subscribe to Common

                              Price  (defined  above) thereof as of the close of
                              business  on the  last  business  day of the  week
                              preceding such insurance of rights shall be deemed
                              to constitute  the payment of a dividend in Common
                              Stock  (and the  record  date  therefore  shall be
                              deemed to have been fixed as the date of insurance

                              of such  rights)of  that number of shares which is

                              as of such time into the  difference  between  (A)
                              the  total  Market  Price  as of such  time of the
                              number of shares purchasable upon exercise of such
                              rights  and (B) the total  offering  price of such

                              shall  not be  counted  and no  adjustment  in the
                              conversion rate will be made for those shares. The
                              twenty million  (20,000,000) share amount shall be
                              proportionately   adjusted   in  the   event   the
                              Corporation  subdivided the outstanding  shares of
                              its Common  Stock into a greater  number of shares
                              or combines  them into a smaller  number of shares
                              prior to January 1st, 1995.

                        share  thereof  into the kind and  amount  of  shares or
                        stock or other  securities or property  receivable  upon
                        such  reclassification,  change, merger or consolidation

                              and the  Transfer  Agents for the Common Stock and
                              thereafter  (until  further  adjusted)  conversion
                              rate  shall be as set  forth in such  certificate;
