                                       OF

                          CERTIFICATE OF INCORPORATION
 
                      AEROSOL SERVICES HOLDING CORPORATION

          Aerosol Services Holding Corporation, a Delaware corporation, 
pursuant to Section 241 of the General Corporation Law of Delaware, hereby 
certifies on February 14, 1994, that:

          FIRST:  The Corporation has not received any payment for any of its 
stock.

          SECOND:  The elected directors of the Corporation have adopted the 
following resolution amending the Corporation's Certificate of Incorporation:

     FOURTH:   The corporation is authorized to issue 1,000,000 shares of 
common stock, par value of $.001 per share ("Common Stock") and 30,000 shares 
of preferred stock, par value of $.001 per share ("Preferred Stock").

          The rights, preferences, privileges and restrictions granted to and 
imposed upon Preferred Stock are set forth below in this Article Fourth.

     Section 1.   DIVIDENDS.

     (a)  DIVIDENDS.  The holders of Preferred Stock shall be entitled to 
receive, out of any assets at the time legally available therefor and when 
and as declared by the Board of Directors, noncumulative dividends ("Current 
Dividends") in cash equal to Two Dollars and Fifty Cents ($2.50) per share 
per quarter, and no more, accruing from the date of issuance and payable 
quarterly commencing on March 30, 1994 and thereafter on the 30th day of each 
June, September, December and March (each a "Dividend Payment Date").  If 
Current Dividends are not declared and paid with respect to any Dividend 
Payment Date on or before the tenth 

                                       5


day following such Dividend Payment Date, then in lieu of Current Dividends 
with respect to such Dividend Payment Date, the holders of Preferred Stock 
shall be entitled to receive, out of any assets at the time legally available 
therefor and when and as declared by the Board of Directors, cumulative 
dividends ("Deferred Dividends") in cash equal to Three Dollars and 
Twenty-Five Cents ($3.25) per share, and no more, for the quarter preceding 
such Dividend Payment Date, which Deferred Dividends until paid shall be 
increased on each subsequent Dividend Payment Data by (i) Two and One-Half 
Percent (2.5%) if Current Dividends and all Deferred Dividends are paid with 
respect to such subsequent Dividend Payment Date or (ii) Three and 
One-Quarter percent (3.25%) if Current Dividends and all Deferred Dividends 
are not paid with respect to such subsequent Dividend Payment Date.  If any 
partial payment is made with respect to Current Dividends and Deferred 
Dividends, such payment shall first be applied to Deferred Dividends.  If the 
Preferred Stock is not outstanding on each day during any quarter, then 
dividends accrued or payable for such quarter shall be reduced 
proportionately based on the number of days during such quarter in which the 
Preferred Stock is outstanding.  All Current Dividends and Deferred Dividends 
are prior and in preference to any declaration or payment or any distribution 
(as defined in Section 1(b) below) on Common Stock.  Current Dividends shall 
accrue on each share of Preferred Stock from day to day only until the next 
Dividend Payment Date.  Deferred Dividends shall accrue on each share of 
Preferred Stock from day to day from the applicable Dividend Payment Date 
until paid.  Until all accrued dividends on Preferred Stock have been paid, 
or declared and set apart, no distribution shall be paid on, or declared and 
set apart for, any Common Stock.

     (b)  DISTRIBUTION.  The term "distribution" as used in this Section 1 
means the transfer of cash or property without consideration, whether by way 
of dividend or otherwise, payable other than in common Stock, or the purchase 
or redemption of shares of the corporation (other than redemptions set forth 
in Section 3 below or repurchases of Common Stock held by employees of the 
corporation or any of its subsidiaries upon termination of their employment 
pursuant to agreements providing for such repurchase) for cash or property.

     Section 2.   LIQUIDATION RIGHTS.

     (a)  PREFERRED STOCK PREFERENCE.  In the event of any liquidation, 
dissolution or winding up of the corporation, whether voluntary or 
involuntary, the holders of Preferred Stock shall be entitled to be paid out 
of the assets of the corporation available for distribution to its 
stockholders, whether such assets are capital, surplus 

                                       6


or earnings, before any payment or declaration and setting apart for payment 
of any amount shall be made in respect of Common Stock, an amount equal to 
One Hundred Dollars ($100.00) per share, plus an amount equal to all accrued 
and unpaid dividends thereon.  If upon any liquidation, dissolution, or 
winding up of the corporation, whether voluntary or involuntary, the assets 
to be distributed to the holders of Preferred Stock shall be insufficient to 
permit the payment to such stockholders of the full preferential amounts 
stated above, then all of the assets of the corporation to be distributed 
shall be distributed among the holders of Preferred Stock in proportion to 
the number of shares of Preferred Stock then held by them.

     (b)  COMMON STOCK PAYMENT OR DISTRIBUTION.  After the payment or 
distribution to the holders of Preferred Stock of the full preferential 
amounts required by subsection 3(a) and if any assets remain in the 
corporation, the holders of Common Stock then outstanding shall be entitled 
to a payment or distribution of the remaining assets of the corporation.

     (c)  MERGER. CONSOLIDATION OR SALE OF ASSETS.  The merger or 
consolidation of the corporation into or with another corporation in which 
the corporation shall not survive and the stockholders of the corporation 
immediately prior to such transaction shall own less than fifty percent of 
the voting stock of the surviving corporation, and the sale, transfer or 
lease (but not including a transfer or lease by pledge or mortgage to a bona 
fide lender or a transfer by or in connection with a foreclosure by a bona 
fide lender) of all or substantially all of the assets of the corporation, 
shall be deemed to be a liquidation, dissolution or winding up of the 
corporation as those terms as used in this Section 2.

     Section 3.   REDEMPTION OF PREFERRED STOCK.

     (a)  OPTIONAL REDEMPTION.  At any time after February 14, 1999 
[five years after the issuance date] and upon not less than five days prior 
notice to holders of Preferred Stock, the corporation may, at the option of 
the Board of Directors, redeem all or part of the outstanding shares of 
Preferred Stock at a redemption price equal to One Hundred Dollars ($100.00) 
per share, together with all accrued and unpaid dividends to and including 
the redemption date (the "Redemption Price").  Such notice to a holder of 
Preferred Stock (the "Redemption Notice") shall specify the date of 
redemption, the Redemption Price and the number of shares of Preferred Stock 
of such holder to be redeemed, and shall call upon such holder to surrender 
such holder's redeemed stock to the corporation on the redemption date at the 
place designated in the Redemption Notice.  If less than all of the 
outstanding shares of 


                                       7


Preferred Stock are to be redeemed, then the corporation shall redeem a pro 
rata portion from each holder of Preferred Stock according to the respective 
number of shares of Preferred Stock held by such holder.

     (b)  MANDATORY REDEMPTION.  The corporation shall redeem all outstanding 
shares of Preferred Stock at the Redemption Price on the earlier of (i) 
February 14, 2005 [eleven years after the issuance date], or (ii) the 
refinancing of the corporation's Senior Subordinated Notes (the "Notes") at a 
lower interest rate than 12%; PROVIDED that the terms of such refinancing 
shall not reduce the average maturity of the Notes outstanding on the 
effective date of such refinancing or require amortization of principal to 
commence prior to December 31, 2001.  The corporation shall give a Redemption 
Notice to each holder of Preferred Stock at least five days prior thereto.

     (c)  CHANCE OF CONTROL REDEMPTION.

          (l)  A "Change of Control" shall be deemed to have occurred on the 
date on which the stockholders of the corporation on the date of initial 
issuance of Preferred Stock (the "Initial Stockholders") and their affiliates 
cease to directly or indirectly beneficially own 50% or more of the 
outstanding voting power of the corporation; PROVIDED that capital stock of 
the corporation issued to, or held by an employee stock ownership plan of the 
corporation or any of its subsidiaries, shall be disregarded for purposes of 
this definition, and PROVIDED, FURTHER, that capital stock of the corporation 
sold or otherwise transferred by an Initial Stockholder or any of its 
affiliates to such employee stock ownership plan shall be deemed held by an 
Initial Stockholder.  The corporation shall give written notice of a Change 
of Control to the holders of Preferred Stock within ten days thereafter.

          (2)  At the option of the holders of a majority of Preferred Stock 
exercised by written notice (the "Election Notice") given to the corporation 
within thirty days after the Change of Control, the corporation shall redeem 
all outstanding shares of Preferred Stock at the Redemption Price on the 
redemption date specified in the Election Notice (which Redemption Date shall 
be not less than sixty nor more than ninety days after the Change of 
Control).  Upon receipt of the Election Notice, the corporation shall give a 
Redemption Notice to each holder of Preferred Stock.

     (d)  RIGHTS OF HOLDERS AFTER REDEMPTION DATE.  On or after the 
redemption date, each holder of shares of Preferred Stock called for 
redemption shall surrender the certificate evidencing such shares to the 
corporation at the place 

                                       8


designated in the Redemption Notice and shall thereupon be entitled to 
receive payment of the Redemption Price.  From and after the redemption date 
(unless the corporation fails to pay the Redemption Price in which case all 
the rights of the holders of Preferred Stock shall continue), the holders of 
the shares of Preferred Stock called for redemption shall cease to have any 
rights as holders of Preferred Stock of the corporation except the right to 
receive, without interest, the Redemption Price thereof upon surrender of 
certificates representing such shares, and such shares shall not thereafter 
be transferred (except with the consent of the corporation) on the books of 
the corporation and shall not be deemed outstanding for any purpose 
whatsoever.  Any money deposited for the redemption of shares of Preferred 
Stock which is unclaimed by a holder of Preferred Stock for two years after 
the redemption date thereof shall be returned to the corporation.

     (e)  RESTRICTIONS ON REDEMPTION.  The corporation shall not redeem any 
Preferred Stock where such action would be in violation of applicable law.

     Section 4.   VOTING RIGHTS.  Except as otherwise required by law, the 
holders of Preferred Stock shall not be entitled to vote on any matter.  
Except as otherwise required by law, in all cases where the holders of 
Preferred Stock have the right to vote, the holders of Preferred Stock and 
the holders of Common Stock shall vote together and not as separate classes 
and the holders of Preferred Stock shall be entitled to one vote for each 
share of Preferred Stock held by them.

     Section 5.   NO REISSUANCE OF PREFERRED STOCK.  Shares of Preferred 
Stock acquired by the corporation by reason of redemption, purchase, 
conversion or otherwise shall not be reissued, and all such shares shall be 
cancelled, retired and eliminated from the shares which the corporation shall 
be authorized to issue.

          THIRD:  The foregoing amendment to the Certificate of Incorporation 
of the Corporation has been duly adopted in accordance with the provisions of 
Section 241 of the General Corporation Law of Delaware.

              Section 1.  DIVIDENDS.

              (a)  DIVIDENDS -- SERIES A PREFERRED STOCK.  The holders of 
          Series A Preferred Stock shall be entitled to receive, out of any 
          assets at the time legally available therefor and when and as 
          declared by the Board of Directors, noncumulative dividends 
          ("Series A Current Dividends") in cash equal to Two Dollars and 
          Fifty Cents ($2.50) per share per quarter, and no more, accruing

          30, 1994 and thereafter on the 30th day of each June, September, 
          December and March (each a "Series A Dividend Payment Date").  If 
          Series A Current Dividends are not declared and paid with respect 
          to any Series A Dividend Payment Date on or before the tenth day 
          following such Series A Dividend Payment Date, then in lieu of 
          Series A Current Dividends with respect to such Series A Dividend 
          Payment Date, the holders of Series A Preferred Stock shall be 
          entitled to receive, out of any assets at the time legally 
          available therefor and when and as declared by the Board of 
          Directors, cumulative dividends ("Series A Deferred Dividends") in

          share, and no more, for the quarter preceding such Series A

          shall be increased on each subsequent Series A Dividend Payment 
          Date by (i) Two and One-Half Percent (2.5%) if Series A Current 
          Dividends and all Series A Deferred Dividends are paid with respect 
          to such subsequent Series A Dividend Payment Date or (ii) Three and 
          One-Quarter percent (3.25%) if Series A Current Dividends and all 
          Series A Deferred Dividends are not paid with respect to such 
          subsequent Series A Dividend Payment Date.  If any partial payment 
          is made with respect to Series

          A Current Dividends and Series A Deferred Dividends, such payment 
          shall first be applied to Series A Deferred Dividends.  If the 
          Series A Preferred Stock is not outstanding on each day during any 
          quarter, then dividends accrued or payable for such quarter shall 
          be reduced proportionately based on the number of days during such 
          quarter in which the Series A Preferred Stock is outstanding.  All 
          Series A Current Dividends and Series A Deferred Dividends are 
          prior and in preference to any declaration or payment of any 
          distribution (as defined in Section 1(c) below) on Common Stock.  
          Series A Current Dividends shall accrue on each share of Series A 
          Preferred Stock from day to day only until the next Series A 
          Dividend Payment Date.  Series A Deferred Dividends shall accrue on 
          each share of Series A Preferred Stock from day to day from the 
          applicable Series A Dividend Payment Date until paid.  Until all 
          accrued dividends on Series A Preferred Stock have been paid, or 
          declared and set apart, no distribution shall be paid on, or 
          declared and set apart for, any Common Stock.

              (b)  DIVIDENDS -- SERIES B PREFERRED STOCK.  The holders of 
          Series B Preferred Stock shall be entitled to receive, out of any 
          assets at the time legally available therefor and when and as

          quarter, and no more, accruing from June 30, 1997 and payable 
          quarterly commencing on September 30, 1997 and thereafter on the 
          30th day of each December, March, June and September until 
          redemption of the Series B Preferred Stock.  If the Series B 
          Preferred Stock is not outstanding on each day of any quarter, then 
          dividends accrued or payable for such quarter shall be reduced 
          proportionately based on the number of days during such quarter in 
          which the Series B Preferred Stock is outstanding.  The Series B 
          Dividends shall accrue and be cumulative whether or not they have 
          been declared and whether or not there are profits, surplus or 
          other funds of the Corporation legally available therefore.  All 
          Series B Dividends are prior and in preference to any declaration 
          or payment of any distribution (as defined in Section 1(c) below) 
          on Common Stock.  Until all accrued dividends on Series B Preferred 
          Stock have been paid, or declared and set apart, no distribution 
          shall be paid on, or declared and set apart for, any Common Stock.  
          Notwithstanding anything to the contrary contained herein, the 
          Board of Directors shall not be required to declare and pay 
          dividends on the Series B Preferred Stock solely because it has 
          declared and paid dividends on the Series A Preferred Stock.  The 
          Board of Directors shall timely declare and pay dividends on Series 
          B Preferred Stock as described in this Section 1(b) from assets 
          legally available therefore unless prevented by restrictions or 
          limitations imposed from time to time by lenders to the Corporation.

                                       13



               (c)  DISTRIBUTION.  The term "distribution" as used in this 
          Section 1 means the transfer of cash or property without 
          consideration, whether by way of dividend or otherwise, payable 
          other than in Common Stock or the purchase or redemption of shares 
          of the Corporation (other than redemptions set forth in Section 3 
          below or repurchases of Common Stock held by employees of the 
          Corporation or any of its subsidiaries upon termination of their 
          employment pursuant to agreements providing for such repurchase) 
          for cash or property.

               Section 2.  LIQUIDATION RIGHTS.
 
              (a)  PREFERRED STOCK PREFERENCE.  In the event of any 
          liquidation, dissolution or winding up of the Corporation, whether 
          voluntary or involuntary, the holders of Preferred Stock shall be 
          entitled to be paid out of the assets of the Corporation available 
          for distribution to its stockholders, whether such assets are 
          capital, surplus or earnings, before any payment or declaration and 
          setting apart for payment of any amount shall be made in respect of 
          Common Stock, with respect to holders of (1) the Series A Preferred 
          Stock, an amount equal to One Hundred Dollars ($100.00) per share, 
          plus an amount equal to all accrued and unpaid dividends thereon 
          through the date of redemption (the "Series A Redemption Price"), 
          and (2) the Series B Preferred Stock, an amount equal to One 
          Hundred Forty-Five and 97/100 Dollars ($145.97) per share, plus an 
          amount equal to all accrued and unpaid dividends thereon through 
          the date of redemption (the "Series B Redemption Price"; the Series 
          A Redemption Price and the Series B Redemption Price are each a 
          "Redemption Price").  If upon any liquidation, dissolution or 
          winding up of the Corporation, whether voluntary or involuntary, 
          the assets to be distributed to the holders of Preferred Stock 
          shall be insufficient to permit the payment to such stockholders of 
          the full preferential amounts stated above, then all of the assets 
          of the Corporation to be distributed shall be distributed among the 
          holders of Preferred Stock in proportion to the amounts due to such 
          holders hereunder.

                (b)  COMMON STOCK PAYMENT OR DISTRIBUTION.  After the payment 
          or distribution to the holders of Preferred Stock of the full 
          preferential amounts required by Section 2(a) and if any assets 
          remain in the Corporation, the holders of Common Stock then 
          outstanding shall be entitled to a payment or distribution of the 
          remaining assets of the Corporation.

                (c)  MERGER, CONSOLIDATION OR SALE OF ASSETS.  The merger or 
          consolidation of the Corporation into or with another corporation 
          in which the 


                                       14


          Corporation shall not survive and the stockholders of the 
          Corporation immediately prior to such transaction shall own less 
          than fifty percent of the voting stock of the surviving 
          Corporation, and the sale, transfer or lease (but not including a 
          transfer or lease by pledge or mortgage to a bona fide lender or a 
          transfer by or in connection with a foreclosure by a bona fide 
          lender) of all or substantially all of the assets of the 
          Corporation, shall be deemed to be a liquidation, dissolution or 
          winding up of the Corporation as those terms are used in this 
          Section 2 and Section 3.

               Section 3.  REDEMPTION OF PREFERRED STOCK.  

               (a)  OPTIONAL REDEMPTION.  At any time after the completion of 
          an offering by the Corporation of its shares of Common Stock 
          pursuant to an effective registration statement filed with the 
          Securities and Exchange Commission or at any time after June 30, 
          2000, and upon not less than five days prior notice to holders of 
          Preferred Stock of a Series thereof, the Corporation may, at the 
          option of the Board of Directors, redeem all or part of the 
          outstanding shares of Preferred Stock or a Series thereof at the 
          applicable Redemption Price.  Such notice to a holder of Preferred 
          Stock (the "Redemption Notice") shall specify the date of 
          redemption, the applicable Redemption Price and the number of 
          shares of Preferred Stock of such holder to be redeemed, and shall 
          call upon such holder to surrender such holder's redeemed stock to 
          the Corporation on the Redemption Date at the place designated in 
          the Redemption Notice.  If less than all of the outstanding shares 
          of Preferred Stock or a Series thereof are to be redeemed, then the 
          Corporation shall redeem a pro rata portion from each holder of 
          Preferred Stock or Series thereof according to the respective 
          number of shares of Preferred Stock or Series thereof held by such 
          holder.

                (b)  MANDATORY REDEMPTION.  The Corporation shall redeem all 
          outstanding shares of Preferred Stock at the applicable Redemption 
          Price on the earlier to occur of (i) a liquidation, dissolution or 
          winding up of the Corporation, (ii) an initial public offering of 
          the Corporation's common stock pursuant to an effective 
          registration statement registered under the Securities Exchange Act 
          of 1933, which results in net proceeds to the Corporation of not 
          less than 20,000,000 and (iii) June 30, 2006.  The Corporation 
          shall give a Redemption Notice to each holder of Preferred Stock at 
          least five days prior thereto.

                (c)  CHANGE OF CONTROL REDEMPTION.

                                       15



                       (1)  A "Change of Control" shall be deemed to have 
          occurred on the date on which the stockholders of the Corporation 
          on the day immediately preceding the event that gives rise to the 
          Change of Control (the "Prior Stockholders") and their affiliates 
          cease to directly or indirectly beneficially own 50% or more of the 
          outstanding voting power of the Corporation; PROVIDED that capital 
          stock of the Corporation issued to, or held by an employee stock 
          ownership plan of the Corporation or any of its subsidiaries, shall 
          be disregarded for purposes of this definition, and PROVIDED, 
          FURTHER, that capital stock of the Corporation sold or otherwise 
          transferred by a Prior Stockholder or any of its affiliates to such 
          employee stock ownership plan shall be deemed held by a Prior 
          Stockholder.  The Corporation shall give written notice of a Change 
          of Control to the holders of Preferred Stock within ten days 
          thereafter.

                      (2)  At the option of the holders of a majority of the 
          Preferred Stock exercised by written notice (the "Election Notice") 
          given to the Corporation within thirty days after the Change of 
          Control, the Corporation shall redeem (a "Change of Control 
          Redemption") all outstanding shares of Preferred Stock at the 
          applicable Redemption Price on the Redemption Date specified in the 
          Election Notice (which Redemption Date shall be not less than sixty 
          nor more than ninety days after the Change of Control).  Upon 
          receipt of the Election Notice, the Corporation shall give a 
          Redemption Notice to each holder of Preferred Stock.

                (d)  RIGHTS OF HOLDERS AFTER REDEMPTION DATE.  On or after 
          the Redemption Date, each holder of shares of Preferred Stock 
          called for redemption shall surrender the certificate evidencing 
          such shares to the Corporation at the place designated in the 
          Redemption Notice and shall thereupon be entitled to receive 
          payment of the applicable Redemption Price.  From and after the 
          Redemption Date (unless the Corporation fails to pay the applicable 
          Redemption Price in which case all the rights of the holders of 
          Preferred Stock shall continue), the holders of the shares of 
          Preferred Stock called for redemption shall cease to have any 
          rights as holders of Preferred Stock of the Corporation except the 
          right to receive, without interest, the applicable Redemption Price 
          thereof upon surrender of certificates representing such shares, 
          and such shares shall not thereafter be transferred (except with 
          the consent of the Corporation) on the books of the Corporation and 
          shall not be deemed outstanding for any purposes whatsoever.  Any 
          money deposited for the redemption of shares of Preferred Stock 
          which is unclaimed by a holder of Preferred Stock for two years 
          after the Redemption Date thereof shall be returned to the 
          Corporation.

                                       16



                (e)  RESTRICTIONS ON REDEMPTION.  The Corporation shall not 
          redeem any Preferred Stock where such action would be in violation 
          of applicable law.

                Section 4.  VOTING RIGHTS.  Except as otherwise required by 
          law, the holders of Preferred Stock shall not be entitled to vote 
          on any matter.  Except as otherwise required by law, in all cases 
          where the holders of Preferred Stock have the right to vote, the 
          holders of Preferred Stock and the holders of Common Stock shall 
          vote together and not as separate classes and the holders of 
          Preferred Stock shall be entitled to one vote for each share of 
          Preferred Stock held by them.

                Section 5.  NO REISSUANCE OF PREFERRED STOCK.  Shares of 
          Preferred Stock acquired by the Corporation by reason of 
          redemption, purchase, conversion or otherwise shall not be 
          reissued, and all such shares shall be cancelled, retired and 
          eliminated from the shares which the Corporation shall be 
          authorized to issue."

          5.   The executed Agreement and Plan of Merger is on file at the 
principal place of business of ASHC at 425 Ninth Avenue, City of Industry, 
California 91746.

          6.   A copy of the Agreement and Plan of Merger will be furnished

                            CERTIFICATE OF AMENDMENT
                                       OF
                          CERTIFICATE OF INCORPORATION
                                       OF
                        OUTSOURCING SERVICES GROUP, INC.


     Outsourcing Services Group, Inc., a corporation organized and existing 
under the General Corporation Law of the State of Delaware (the 
"Corporation"), does hereby certify as follows:

     1.   The Board of Directors of the Corporation and the stockholders of 
the Corporation have duly adopted resolutions setting forth a proposed 
amendment to Article FOURTH of the Certificate of Incorporation of the 
Corporation.  The resolution setting forth the proposed amendment is as 
follows:

     RESOLVED, that Article FOURTH of the Corporation's Certificate of
     Incorporation is hereby amended to read in its entirety as follows:

     "FOURTH:  The corporation is authorized to issue two classes of shares
     designated respectively "Common Stock" and "Preferred Stock."  The
     Common Stock shall consist of 6,000,000 authorized shares, par value
     of $.001 per share.  The Preferred Stock shall consist of 30,000
     authorized shares and shall be issued in series.  The first such
     series shall be designated "Series A Preferred Stock" and shall
     consist of 3,750 shares, par value of $.001 per share.  The second
     series shall be designated "Series B Preferred Stock" and shall
     consist of 26,250 shares, par value of $.001 per share.

          The rights, preferences, privileges and restrictions granted to
     and imposed upon Preferred Stock are set forth below in this Article
     Fourth.

          Section 6.  DIVIDENDS.

          (a)  DIVIDENDS -- SERIES A PREFERRED STOCK.  The holders of
     Series A Preferred Stock shall be entitled to receive, out of any
     assets at the time legally available therefor and when and as declared
     by the Board of Directors, noncumulative dividends ("Series A Current
     Dividends") in cash equal to Two Dollars and Fifty Cents ($2.50) per
     share per quarter, and no more, accruing from February 14, 1994 and
     payable quarterly commencing on March 30, 1994 and thereafter on the
     30th day of each June, September, December and March (each a "Series A
     Dividend Payment Date").  If Series A Current Dividends are 


                                       19



     not declared and paid with respect to any Series A Dividend Payment Date
     on or before the tenth day following such Series A Dividend Payment
     Date, then in lieu of Series A Current Dividends with respect to such
     Series A Dividend Payment Date, the holders of Series A Preferred
     Stock shall be entitled to receive, out of any assets at the time
     legally available therefor and when and as declared by the Board of
     Directors, cumulative dividends ("Series A Deferred Dividends") in
     cash equal to Three Dollars and Twenty-Five Cents ($3.25) per share,
     and no more, for the quarter preceding such Series A Dividend Payment
     Date, which Series A Deferred Dividends until paid shall be increased
     on each subsequent Series A Dividend Payment Date by (i) Two and One-
     Half Percent (2.5%) if Series A Current Dividends and all Series A
     Deferred Dividends are paid with respect to such subsequent Series A
     Dividend Payment Date or (ii) Three and One-Quarter percent (3.25%) if
     Series A Current Dividends and all Series A Deferred Dividends are not
     paid with respect to such subsequent Series A Dividend Payment Date. 
     If any partial payment is made with respect to Series A Current
     Dividends and Series A Deferred Dividends, such payment shall first be
     applied to Series A Deferred Dividends.  If the Series A Preferred
     Stock is not outstanding on each day during any quarter, then
     dividends accrued or payable for such quarter shall be reduced
     proportionately based on the number of days during such quarter in
     which the Series A Preferred Stock is outstanding.  All Series A
     Current Dividends and Series A Deferred Dividends are prior and in
     preference to any declaration or payment of any distribution (as
     defined in Section 1(c) below) on Common Stock.  Series A Current
     Dividends shall accrue on each share of Series A Preferred Stock from
     day to day only until the next Series A Dividend Payment Date.  Series
     A Deferred Dividends shall accrue on each share of Series A Preferred
     Stock from day to day from the applicable Series A Dividend Payment
     Date until paid.  Until all accrued dividends on Series A Preferred
     Stock have been paid, or declared and set apart, no distribution shall
     be paid on, or declared and set apart for, any Common Stock.

          (b)  DIVIDENDS -- SERIES B PREFERRED STOCK.  The holders of
     Series B Preferred Stock shall be entitled to receive, out of any
     assets at the time legally available therefor and when and as declared
     by the Board of Directors, cumulative dividends ("Series B
     Dividends"), in cash equal to Two Dollars ($2.00) per share per
     quarter, and no more, accruing from June 30, 1997 and payable
     quarterly commencing on September 30, 1997 and thereafter on the 30th
     day of each December, March, June and September until redemption of
     the Series B Preferred Stock.  If the Series B Preferred Stock is not
     outstanding on each day of any quarter, then dividends accrued or
     payable for such quarter shall be reduced proportionately based on the
     number of days during such quarter in which the Series B Preferred
     Stock is outstanding.  The Series B Dividends shall 


                                       20


     accrue and be cumulative whether or not they have been declared and 
     whether or not there are profits, surplus or other funds of the 
     Corporation legally available therefore.  All Series B Dividends are 
     prior and in preference to any declaration or payment of any 
     distribution (as defined in Section 1(c) below) on Common Stock.  Until 
     all accrued dividends on Series B Preferred Stock have been paid, or 
     declared and set apart, no distribution shall be paid on, or declared 
     and set apart for, any Common Stock.  Notwithstanding anything to the 
     contrary contained herein, the Board of Directors shall not be required 
     to declare and pay dividends on the Series B Preferred Stock solely 
     because it has declared  and paid dividends on the Series A Preferred 
     Stock.  The Board of Directors shall timely declare and pay dividends on 
     Series B Preferred Stock as described in this Section 1(b) from assets 
     legally available therefore unless prevented by restrictions or 
     limitations imposed from time to time by lenders to the Corporation.

          (c)  DISTRIBUTION.  The term "distribution" as used in this
     Section 1 means the transfer of cash or property without
     consideration, whether by way of dividend or otherwise, payable other
     than in Common Stock or the purchase or redemption of shares of the
     Corporation (other than redemptions set forth in Section 3 below or
     repurchases of Common Stock held by employees of the Corporation or
     any of its subsidiaries upon termination of their employment pursuant
     to agreements providing for such repurchase) for cash or property.

          Section 7.  LIQUIDATION RIGHTS.

          (a)  PREFERRED STOCK PREFERENCE.  In the event of any
     liquidation, dissolution or winding up of the Corporation, whether
     voluntary or involuntary, the holders of Preferred Stock shall be
     entitled to be paid out of the assets of the Corporation available for
     distribution to its stockholders, whether such assets are capital,
     surplus or earnings, before any payment or declaration and setting
     apart for payment of any amount shall be made in respect of Common
     Stock, with respect to holders of (1) the Series A Preferred Stock, an
     amount equal to One Hundred Dollars ($100.00) per share, plus an
     amount equal to all accrued and unpaid dividends thereon through the
     date of redemption (the "Series A Redemption Price"), and (2) the
     Series B Preferred Stock, an amount equal to One Hundred Forty-Five
     and 97/100 Dollars ($145.97) per share, plus an amount equal to all
     accrued and unpaid dividends thereon through the date of redemption
     (the "Series B Redemption Price"; the Series A Redemption Price and
     the Series B Redemption Price are each a "Redemption Price").  If upon
     any liquidation, dissolution or winding up of the Corporation, whether
     voluntary or involuntary, the assets to be distributed to the holders
     of Preferred Stock shall be insufficient 

                                       21


     to permit the payment to such stockholders of the full preferential 
     amounts stated above, then all of the assets of the Corporation to be 
     distributed shall be distributed among the holders of Preferred Stock in 
     proportion to the amounts due to such holders hereunder.

          (b)  COMMON STOCK PAYMENT OR DISTRIBUTION.  After the payment or
     distribution to the holders of Preferred Stock of the full
     preferential amounts required by Section 2(a) and if any assets remain
     in the Corporation, the holders of Common Stock then outstanding shall
     be entitled to a payment or distribution of the remaining assets of
     the Corporation.

          (c)  MERGER, CONSOLIDATION OR SALE OF ASSETS. The merger or
     consolidation of the Corporation into or with another corporation in
     which the Corporation shall not survive and the stockholders of the
     Corporation immediately prior to such transaction shall own less than
     fifty percent of the voting stock of the surviving Corporation, and
     the sale, transfer or lease (but not including a transfer or lease by
     pledge or mortgage to a bona fide lender or a transfer by or in
     connection with a foreclosure by a bona fide lender) or all or
     substantially all of the assets of the Corporation, shall be deemed to
     be a liquidation, dissolution or winding up of the Corporation as
     those terms are used in this Section 2 and Section 3.

          Section 8.  REDEMPTION OF PREFERRED STOCK.  

          (a)  OPTIONAL REDEMPTION.  At any time after the completion of an
     offering by the Corporation of its shares of Common Stock pursuant to
     an effective registration statement filed with the Securities and
     Exchange Commission or at any time after June 30, 2000, and upon not
     less than five days prior notice to holders of Preferred Stock of a
     Series thereof, the Corporation may, at the option of the Board of
     Directors, redeem all or part of the outstanding shares of Preferred
     Stock or a Series thereof at the applicable Redemption Price.  Such
     notice to a holder of Preferred Stock (the "Redemption Notice") shall
     specify the date of redemption, the applicable Redemption Price and
     the number of shares of Preferred Stock of such holder to be redeemed,
     and shall call upon such holder to surrender such holder's redeemed
     stock to the Corporation on the Redemption Date at the place
     designated in the Redemption Notice.  If less than all of the
     outstanding shares of Preferred Stock or a Series thereof are to be
     redeemed, then the Corporation shall redeem a pro rata portion from
     each holder of Preferred Stock or Series thereof according to the
     respective number of shares of Preferred Stock or Series thereof held
     by such holder.

                                       22



          (b)  MANDATORY REDEMPTION.  The Corporation shall redeem all
     outstanding shares of Preferred Stock at the applicable Redemption
     Price on the earlier to occur of (i) a liquidation, dissolution or
     winding up of the Corporation, (ii) an initial public offering of the
     Corporation's common stock pursuant to an effective registration
     statement registered under the Securities Exchange Act of 1933, which
     results in net proceeds to the Corporation of not less than
     $20,000,000 and (iii) June 30, 2010.  The Corporation shall give a
     Redemption Notice to each holder of Preferred Stock at least five days
     prior thereto.

          (c)  CHANGE OF CONTROL REDEMPTION.

               (1)   A "Change of Control" shall be deemed to have occurred 
          on the date on which the stockholders of the Corporation on the day 
          immediately preceding the event that gives rise to the Change of 
          Control (the "Prior Stockholders") and their affiliates cease to 
          directly or indirectly beneficially own 50% or more of the 
          outstanding voting power of the Corporation; PROVIDED that capital 
          stock of the Corporation issued to, or held by an employee stock 
          ownership plan of the Corporation or any of its subsidiaries, shall 
          be disregarded for purposes of this definition, and PROVIDED, 
          FURTHER, that capital stock of the Corporation sold or otherwise 
          transferred by a Prior Stockholder or any of its affiliates to such 
          employee stock ownership plan shall be deemed held by a Prior 
          Stockholder.  The Corporation shall give written notice of a Change 
          of Control to the holders of Preferred Stock within ten days 
          thereafter.

               (2)  At the option of the holders of a majority of the 
          Preferred Stock exercised by written notice (the "Election Notice") 
          given to the Corporation within thirty days after the Change of 
          Control, the Corporation shall redeem (a "Change of Control 
          Redemption") all outstanding shares of Preferred Stock at the 
          applicable Redemption Price on the Redemption Date specified in the 
          Election Notice (which Redemption Date shall be not less than sixty 
          nor more than ninety days after the Change of Control).  Upon 
          receipt of the Election Notice, the Corporation shall give a 
          Redemption Notice to each holder of Preferred Stock.

          (d)  RIGHTS OF HOLDERS AFTER REDEMPTION DATE.  On or after the
     Redemption Date, each holder of shares of Preferred Stock called for
     redemption shall surrender the certificate evidencing such shares to
     the Corporation at the 


                                       23


     place designated in the Redemption Notice and shall thereupon be 
     entitled to receive payment of the applicable Redemption Price.  From 
     and after the Redemption Date (unless the Corporation fails to pa the 
     applicable Redemption Price in which call all the rights of the holders 
     of Preferred Stock shall continue), the holders of the shares of 
     Preferred Stock called for redemption shall cease to have any rights as 
     holders of Preferred Stock of the Corporation except the right to 
     receive, without interest, the applicable Redemption Price thereof upon 
     surrender of certificates representing such shares, and such shares 
     shall not thereafter be transferred (except with the consent of the 
     Corporation) on the books of the Corporation and shall not be deemed 
     outstanding for any purposes whatsoever.  Any money deposited for the 
     redemption of shares of Preferred Stock which is unclaimed by a holder 
     of Preferred Stock for two years after the Redemption Date thereof shall 
     be returned to the Corporation.

          (e)  RESTRICTIONS ON REDEMPTION. The Corporation not redeem any
     Preferred Stock where such action would be in violation of applicable
     law.

          Section 9.  VOTING RIGHTS.  Except as otherwise required by law,
     the holders of Preferred Stock shall not be entitled to vote on any
     matter.  Except as otherwise required by law, in all cases where the
     holders of Preferred Stock have the right to vote, the holders of
     Preferred Stock and the holders of Common Stock shall vote together
     and not as separate classes and the holders of Preferred Stock shall
     be entitled to one vote for each share of Preferred Stock held by
     them.

          Section 10.  NO REISSUANCE OF PREFERRED STOCK.  Shares of
     Preferred Stock acquired by the Corporation by reason of redemption,
     purchase, conversion or otherwise shall not be reissued, and all such
     shares shall be cancelled, retired and eliminated from the shares
     which the Corporation shall be authorized to issue."

     2.   The necessary number of issued and outstanding shares required by
statute were voted in favor of the amendment.
  
     3.   Such amendment was duly adopted in accordance with the provisions of
Section 242 and 228 of the General Corporation Law of the State of Delaware.
