                               A. PREFERRED STOCK

Part 1. DIVIDENDS.

        1A. GENERAL OBLIGATION. When, as and if declared by the Board of
Directors of the Corporation, and to the extent permitted under the General
Corporation Law of the State of Delaware, the Corporation will pay
preferential cumulative dividends out of funds legally available for the
payment of dividends to the holders of Preferred Stock at the times and in
the amounts provided for in this Part 1. Except as otherwise provided herein,
cumulative dividends on Preferred Stock will accrue on a daily basis
(computed on the basis of a 360-day year of twelve 30-day months) at the rate
of 14% of the Stated Value per year (subject to adjustment as provided in
Part 5), from and including the date of issuance of such Preferred Stock to
but excluding the date on which the Redemption Price of such Preferred Stock
is paid. Such dividends will 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 for the payment of dividends. The
date on which the Corporation initially issues any share of Preferred Stock
will be deemed to be its "date of issuance" regardless of the number of times
transfer of such share of Preferred Stock is made on the stock records of the
Corporation, and regardless of the number of certificates which may be issued
to evidence such share of Preferred Stock.

        1B. PAYMENT OF DIVIDENDS. Dividends accrued on the Preferred Stock
shall be payable on March 31, June 30, September 30 and December 31 in each
year (each such date being herein referred to as a "Dividend Reference
Date"), commencing on June 30, 1990. Such dividends shall be paid to the
holders of record at the close of business on the date specified by the Board
of Directors at the time such dividend is declared; PROVIDED, HOWEVER, that
such date shall not be more than ten days prior to the respective Dividend
Reference Date. To the extent not paid on any Dividend Reference Date, all
dividends which have accrued on each share of Preferred Stock then
outstanding during the period from and including the immediately preceding
Dividend Reference Date (or from the date of original issue of the Preferred
Stock in the case of the initial Dividend Reference Date) to such Dividend
Reference Date will be added to the Stated Value of such share of Preferred
Stock and will remain a part thereof until such dividends are paid. Any
dividends payable with respect to the Preferred Stock during the first three
years after the date of issuance may be paid (subject to restrictions under
applicable state law), in the sole discretion of the Board of Directors, in
cash or by issuing additional fully paid and nonassessable shares of
Preferred Stock, having an aggregate Stated Value equal to the amount of such
dividend, and the

                                      -2-


<Page>

issuance of such additional shares shall constitute full payment of such
dividend. Dividends payable with respect to the Preferred Stock after the
first three years after the date of issuance are payable only in cash. All
shares of Preferred Stock which may be issued as a dividend with respect to
the Preferred Stock will thereupon be duly authorized, validly issued, fully
paid and nonassessable and free of all liens and charges.

        1C. DISTRIBUTION OF PARTIAL DIVIDEND PAYMENTS. If at any time the
Corporation distributes less than the total amount of dividends then accrued
with respect to Preferred Stock, such payment will be distributed among the
holders of Preferred Stock so that an equal amount will be paid (as nearly as
possible) with respect to each outstanding share of Preferred Stock.

        1D. PRIORITY. So long as any Preferred Stock remains outstanding,
neither the Corporation nor any of its subsidiaries will redeem, purchase or
otherwise acquire any Junior Securities, nor will the Corporation declare or
pay any dividend or make any distribution upon Junior Securities if
immediately after such redemption, purchase, acquisition, dividend or
distribution any Event of Noncompliance of the type described in paragraphs
(1) or (2) of Subpart 5A would exist with respect to the Preferred Stock, or
if the Corporation shall have failed to pay the full amount of dividends
accrued on the Preferred Stock as of the most recent Dividend Reference Date.

        1E. LIMITATION ON DIVIDEND RESTRICTIONS. The Corporation shall not,
and shall not permit any of its subsidiaries to, agree to any provision in
any agreement (other than those in the Master Agreement as of the date hereof
and the Subordinated Note Agreement as of the date hereof or in connection
with any refinancing or refunding thereof which is no more restrictive than
the restrictions contained in the Master Agreement on the date hereof or in
the Subordinated Note Agreement as of the date hereof) which would impose any
restrictions on the Corporation's right to declare and pay dividends on or
make any mandatory redemption of Preferred Stock.

Part 2. LIQUIDATION.

        Upon any voluntary or involuntary liquidation, dissolution or winding
up of the affairs of the Corporation, the holders of shares of Preferred
Stock then outstanding will be entitled to be paid out of the assets of the
Corporation available for distribution to stockholders (whether from capital,
surplus or earnings), before any distribution or payment is made upon any
Junior Securities of the Corporation, an amount in cash equal to the
aggregate Liquidation Value of all Preferred Stock outstanding to the date
fixed for liquidation, dissolution or winding up. The holders of Preferred
Stock will not be entitled


                                       -3-


<Page>

to any further payment. If, upon any such liquidation, dissolution or winding
up of the Corporation, the assets of the Corporation to be distributed among
the holders of Preferred Stock are insufficient to permit payment to such
holders of the aggregate amount which they are entitled to be paid, then the
entire assets of the Corporation to be distributed to such holders will be
distributed ratably among such holders based upon the aggregate Liquidation
Value of the Preferred Stock held by each such holder. The Corporation will
mail written notice of such liquidation, dissolution or winding up, not less
than 30 days prior to the payment date stated therein, to each record holder
of Preferred Stock. 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 Part
2 unless such consolidation, merger, sale or transfer shall be in connection
with a plan of liquidation, dissolution or winding up of the business of the
Corporation.

Part 3. REDEMPTIONS.

        3A. REDEMPTION AT THE OPTION OF THE CORPORATION. Subject to the legal
availability of funds, any contractual restrictions then binding on the
Corporation (including restrictions under the Master Agreement) and
applicable state law, the Corporation may redeem at its option, at any time,
all or any portion of the Preferred Stock then outstanding at a price per
share of Preferred Stock equal to the Redemption Price.

        3B. MANDATORY REDEMPTION. At the earlier of

            (i) March 30, 2000;

           (ii) the merger of the Corporation with and into another
     corporation whereby the Corporation is not the corporation surviving the
     merger;

          (iii) the sale of all or substantially all of the assets of the
     Corporation;

           (iv) the repurchase by Parent of more than 5% of the Class
     NAMSCO-A Common from terminated Management Stockholders (as defined in
     the Stockholders Agreement);

            (v) the exercise by Parent of its equity call rights pursuant to
     paragraphs 1I or 1J of the Stockholders Agreement or by a Stockholder
     (as defined in the Stockholders Agreement) of its equity put rights
     pursuant to paragraph 1I of the Stockholders Agreement (except if clause
     (iv) above is not triggered);


                                       -4-


<Page>

            (vi)  the date when Section 2.03(b) of the Senior Note Agreement
     is applicable;

           (vii)  the date when Section 2.04(b) of the Subordinated Note
     Agreement is applicable; or

          (viii)  upon acceleration of the Senior Notes issued pursuant to
     the Senior Note Agreement or the Subordinated Notes issued pursuant to
     the Subordinated Note Agreement,

the Corporation will redeem all of the shares of Preferred Stock then
outstanding at a price per share of Preferred Stock equal to the Redemption
Price. If Section 2.03(c) of the Senior Note Agreement becomes applicable and
a holder of Preferred Stock that is entitled to have the Corporation redeem
all or a portion of its Preferred Stock elects to have all or a portion of
its Preferred Stock redeemed, or if Section 2.04(c) of the Subordinated Note
Agreement becomes applicable and a holder of Preferred Stock that is
entitled to have the Corporation redeem all or a portion of its Preferred
Stock elects to have all or a portion of its Preferred Stock redeemed, then
the Corporation will redeem all or a portion of the shares of Preferred Stock
then outstanding so designated by any such holder of Preferred Stock at a
price per share of Preferred Stock equal to the Redemption Price.

        3C.  REDEMPTION PRICE.  For each share of Preferred Stock which is to
be redeemed pursuant to this Part 3, the Corporation will be obligated on (i)
the date designated by the Corporation for redemption of Preferred Stock in
connection with Subpart 3A, (ii) the date any of the events specified in the
first sentence of Subpart 3B occur or (iii) the date specified in Section
2.03(c) of the Senior Note Agreement or Section 2.04(c) of the Subordinated
Note Agreement with respect to any of the events specified in the second
sentence of Subpart 3B (each such date being herein referred to as a
"Redemption Date" as further defined in Part 6) to pay to the holder thereof
(upon surrender, unless otherwise specified in paragraph 9M of the Stock
Purchase Agreement, by such holder at the Corporation's principal office of
the certificate representing such shares of Preferred Stock) an amount in
cash equal to the Redemption Price. If the funds of the Corporation legally
available for redemption of Preferred Stock on any Redemption Date are
insufficient to redeem the total number of shares of Preferred Stock to be
redeemed on such date, those funds which are legally available will be used
to redeem the maximum possible number of shares of Preferred Stock ratably
among the holders of the Preferred Stock to be redeemed. At any time thereafter
when additional funds of the Corporation are legally available for the
redemption of Preferred Stock, such funds will immediately be used to redeem
the balance of the Preferred Stock which the Corporation has become obligated
to redeem on any Redemption Date but which it has not redeemed.


                                      -5-
<Page>

        3D.  NOTICE OF REDEMPTION.  The Corporation will mail written notice
of each redemption of Preferred Stock pursuant to Subpart 3A or to the first
sentence of Subpart 3B (other than clauses (vi) and (vii)) to each record
holder thereof, not more than 60 nor less than 10 days prior to the date on
which such redemption is to be made at such holder's address as the same
appears on the stock register of the Corporation and the Corporation will
give notice of redemption of Preferred Stock pursuant to the second sentence
of Subpart 3B; PROVIDED, HOWEVER, that no failure to give such notice nor any
defect therein shall affect the validity of the proceeding for the redemption
of any shares of Preferred Stock to be redeemed except as to the holder to
whom the Corporation has failed to give said notice or except as to the
holder whose notice was defective. Each such notice shall state: (i) the
Redemption Date; (ii) the number of shares of Preferred Stock to be redeemed
and, if less than all the shares held by such holder are to be redeemed, the
number of shares of Preferred Stock held by such holder to be redeemed; (iii)
the Redemption Price; (iv) the place or places where certificates for such
shares are to be surrendered for payment of the Redemption Price; and (v)
that dividends on the shares to be redeemed will cease to accrue on such
Redemption Date. In case fewer than the total number of shares of Preferred
Stock represented by any certificate are redeemed pursuant to this Part 3, a
new certificate representing the number of unredeemed shares of Preferred
Stock will be issued to the holder thereof without cost to such holder
promptly after surrender of the certificate representing the redeemed shares
of Preferred Stock.

        3E.  DETERMINATION OF THE NUMBER OF SHARES OF EACH HOLDER'S PREFERRED
STOCK TO BE REDEEMED.  The number of shares of Preferred Stock to be redeemed
from each holder thereof in partial redemptions by the Corporation under
Subpart 3A will be the number of shares of Preferred Stock determined by
multiplying the total number of shares of Preferred Stock desired to be
redeemed times a fraction, the numerator of which will be the total number of
shares of Preferred Stock then held by such holder and the denominator of
which will be the total number of shares of Preferred Stock then outstanding.

        3F.  DIVIDENDS AFTER REDEMPTION DATE.  No share of Preferred Stock is
entitled to any dividends accruing after its Redemption Date. On such
Redemption Date all rights of the holder of such share of Preferred Stock
will cease, and such share of Preferred Stock will not be deemed to be
outstanding.

        3G.  REDEEMED OR OTHERWISE ACQUIRED SHARES.  Any shares of Preferred
Stock which are redeemed or otherwise acquired by the Corporation or a
subsidiary will be canceled and will not be reissued, sold or transferred.

Part 4.  VOTING RIGHTS.

        The outstanding shares of Preferred Stock shall have no voting rights
except as required by law and such additional voting rights as are set forth
below.

        4A.  No amendment, modification or waiver will be binding or
effective with respect to any provision of Section A of Article Fourth of
this Restated Certificate of Incorporation unless approved by the affirmative
vote of the holders of at least a majority of the outstanding shares of
Preferred Stock voting together as a separate class.

        4B.  In addition to any other vote or consent of stockholders
required herein, the By-laws of the Corporation or by law, the affirmative
vote of all the holders of the outstanding shares of Preferred Stock, voting
together as a separate class, shall be necessary to change the rate or time
of payment of any dividends on, the time or amount of any redemption of, or
the amount of any payments upon liquidation of the Corporation with respect
to, the priorities afforded by the provisions of Subpart 1D for the benefit
of, shares of Preferred Stock or to amend Part 3 or this Part 4.

        4C.  The affirmative vote of the holders of at least a majority of
the outstanding shares of Preferred Stock voting together as a separate class
shall be necessary to:

                (i) increase the number of authorized shares of Preferred
        Stock or authorize or issue any additional shares of any series of
        Preferred Stock or any shares of capital stock of the Corporation of
        any class, or any security or obligations convertible into any capital
        stock of the Corporation of any class, in each case ranking on a
        parity with or senior to the Preferred Stock as to distribution of
        assets in liquidation or in right of payment of dividends;

               (ii) permit the sale, lease or conveyance of all or
        substantially all of the property or business of the Corporation or
        the consolidation or merger of the Corporation with or into any other
        corporation or the merger of another corporation into the Corporation
        unless in any of the circumstances set forth above the Corporation
        shall have exercised its option to redeem all of the shares of
        Preferred Stock pursuant to Subpart 3A out of legally available funds;
        or

              (iii) change by amendment to the Corporation's Certificate of
        Incorporation or otherwise, the terms or provisions of the Preferred
        Stock so as to adversely affect the powers, special rights and
        preferences of the holders thereof.


                                     -7-
<Page>

         4D. If on any date a total of two quarter-annual dividends on the
Preferred Stock have fully accrued but have not been paid in full (a
"Dividend Arrearage") or if the Corporation fails to make any redemption
payment with respect to the Preferred Stock which it is obligated to make (a
"Redemption Default"), the holders of shares of Preferred Stock, voting
together as a separate class, shall have the right to elect one director to
the Board of Directors from and after such election date. Such right of the
holders of Preferred Stock to vote for the election of such director may be
exercised at any annual meeting or at any special meeting called for such
purpose as hereinafter provided or at any adjournment thereof, or by the
written consent, delivered to the Secretary of the Corporation, of the
holders of a majority of all outstanding shares of Preferred Stock, until all
Dividend Arrearages and Redemption Defaults shall have been paid in full (or
such dividends or redemptions declared or made and funds sufficient therefor
set apart for payment), at which time the term of office of the director so
elected shall terminate automatically. So long as such right to vote
continues (and unless such right has been exercised by written consent of the
holders of a majority of the outstanding shares of Preferred Stock as
hereinabove authorized), the Secretary of the Corporation may call, and upon
the written request of the holders of record of a majority of the outstanding
shares of Preferred Stock addressed to him at the principal office of the
Corporation shall call, a special meeting of the holders of such shares for
the election of such number of directors as provided herein. Such meeting
shall be  held within 30 days after delivery of such request to the
Secretary, at the place and upon the notice provided by law and in the
By-laws for the holding of meetings of stockholders. No such special meeting
or adjournment thereof shall be held on a date less than 30 days before an
annual meeting of stockholders or any special meeting in lieu thereof. If at
any such annual or special meeting or any adjournment thereof the holders of
a majority of the then outstanding shares of Preferred Stock entitled to vote
in such election shall be present or represented by proxy, or if the holders
of a majority of the outstanding shares of Preferred Stock shall have acted
by written consent in lieu of a meeting with respect thereto, then the
authorized number of directors shall be increased by one director, and the
holders of the Preferred Stock shall be entitled to elect such director. The
director so elected shall serve until the next annual meeting or until his or
her successor shall be elected and shall qualify, unless the term of office
of the person so elected as director shall have terminated under the
circumstances set forth in the second sentence of this Subpart 4D. If the
director so elected by the holders of Preferred Stock as a class shall cease
to serve as a director before his or her term shall expire, the holders of
the Preferred Stock then outstanding and entitled to vote for such director
may, by written consent as hereinabove provided, or at a special meeting of
such holders called as provided above,


                                     -8-
<Page>

elect a successor to hold office for the unexpired term of the director whose
place shall be vacant.

Part 5.  EVENTS OF NONCOMPLIANCE.

         5A. DEFINITION.  An Event of Noncompliance ("Event of
Noncompliance") will be deemed to have occurred with respect to Preferred
Stock if:

         (1) the Corporation fails to pay on any Dividend Reference Date the
full amount of dividends then accrued; or

         (2) the Corporation fails to make any redemption payment with respect
to the Preferred Stock which it is obligated to make.

         5B. CONSEQUENCES OF EVENT OF NONCOMPLIANCE.

         (1) From and after the occurrence of an Event of Noncompliance
specified in Subpart 5A(1) above, the rate at which dividends on the
Preferred Stock provided for herein accrue will be increased to 14.25% per
annum of the Stated Value thereof, and such dividend accrual rate will
further increase by .25% from and after the ninetieth day following the
occurrence of such Event of Noncompliance and will further increase by .25%
from and after the end of each succeeding 90 day period thereafter as long as
there is continuing in existence any such Event of Noncompliance, but not to a
rate in excess of 17% per annum. From and after the occurrence of an Event of
Noncompliance specified in Subpart 5A(2) above, the rate at which dividends
on the Preferred Stock provided for herein accrue will be increased to 17%
per annum of the Stated Value thereof so long as there is continuing in
existence any such Event of Noncompliance. From and after such time as there
is no such Event of Noncompliance continuing in existence, dividends on the
Preferred Stock shall accrue at the rate provided for in Part 1 until the
occurrence of another Event of Noncompliance, whereupon the rate at which
dividends on the Preferred Stock will accrue will be increased in the manner
and subject to the conditions set forth in this Subpart 5B.

         (2) If any Event of Noncompliance exists, each holder of Preferred
Stock will also have any other rights which such holder may have been
afforded under any contract or agreement at any time and any other rights
which such holder may have pursuant to applicable law.

         1A.   GENERAL OBLIGATION. When, as and if declared by the Board of
Directors of the Corporation, and to the extent permitted under the General
Corporation Law of the State of Delaware and any contractual restrictions
then binding on the Corporation (including restrictions under the Master
Agreement), the Corporation will pay preferential cumulative dividends out of
funds legally available for the payment of dividends to the holders of Junior
Preferred Stock at the times and in the amounts provided for in this Part 1.
Except as otherwise provided herein, cumulative dividends on Junior Preferred
Stock will accrue on a daily basis (computed on the basis of a 360-day year
of twelve 30-day months) at the rate of 10% of the Stated Value per year,
from and including the date of issuance of such Junior Preferred Stock to but
excluding the date on which the Junior

                                      -12-
<Page>

Preferred Redemption Price of such Junior Preferred Stock is paid. Such
dividends will 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 for the payment of dividends. The date on which
the Corporation initially issues any share of Junior Preferred Stock will be
deemed to be its "date of issuance" regardless of the number of times
transfer of such share of Junior Preferred Stock is made on the stock records
of the Corporation, and regardless of the number of certificates which may be
issued to evidence such share of Junior Preferred Stock.

         1B.  PAYMENT OF DIVIDENDS.  Dividends accrued on the Junior
Preferred Stock shall be payable on June 30 in each year (such date being
herein referred to as a "Junior Preferred Dividend Reference Date"). Such
dividends shall be paid to the holders of record at the close of business on
the date specified by the Board of Directors at the time such dividend is
declared; PROVIDED, HOWEVER, that such date shall not be more than ten days
prior to the respective Junior Preferred Dividend Reference Date. To the
extent not paid on any Junior Preferred Dividend Reference Date, all
dividends which have accrued on each share of Junior Preferred Stock then
outstanding during the period from and including the immediately preceding
Junior Preferred Dividend Reference Date (or from the date of original issue
of the Junior Preferred Stock in the case of the initial Junior Preferred
Dividend Reference Date) to such Junior Preferred Dividend Reference Date
will be added to the Stated Value of such share of Junior Preferred Stock and
will remain a part thereof until such dividends are paid.

         1C.  DISTRIBUTION OF PARTIAL DIVIDEND PAYMENTS.  If at any time the
Corporation distributes less than the total amount of dividends then accrued
with respect to Junior Preferred Stock, such payment will be distributed
among the holders of Junior Preferred Stock so that an equal amount will be
paid (as nearly as possible) with respect to each outstanding share of Junior
Preferred Stock.

         1D.  PRIORITY.  So long as any Junior Preferred Stock remains
outstanding, neither the Corporation nor any of its subsidiaries will redeem,
purchase or otherwise acquire any Junior Stock, nor will the Corporation
declare or pay any dividend or make any distribution upon Junior Stock if
immediately after such redemption, purchase, acquisition, dividend or
distribution the Corporation shall have failed to pay the full amount of
dividends accrued on the Junior Preferred Stock as of the most recent Junior
Preferred Dividend Reference Date.

         1E.  LIMITATION ON DIVIDEND RESTRICTIONS.  The Corporation shall
not, and shall not permit any of its

                                      -13-
<Page>

subsidiaries to, agree to any provision in any agreement (other than those in
the Master Agreement as of the date hereof and the Subordinated Note
Agreement as of the date hereof or in connection with any refinancing or
refunding thereof which is no more restrictive than the restrictions
contained in the Master Agreement on the date hereof or in the Subordinated
Note Agreement as of the date hereof, provided that any such refinancing or
refunding shall not be deemed to be more restrictive merely because the
principal amount of such refinancing or refunding exceeds the principal
amount being refinanced or refunded or because the scheduled repayment date
therefor is later) which would impose any restrictions on the Corporation's
right to declare and pay dividends on or make any mandatory redemption of
Junior Preferred Stock.

Part 2. LIQUIDATION.

        Upon any voluntary or involuntary liquidation, dissolution or winding
up of the affairs of the Corporation, the holders of shares of Junior
Preferred Stock then outstanding will be entitled to be paid out of the
assets of the Corporation available for distribution to stockholders (whether
from capital, surplus or earnings), before any distribution or payment is
made upon any Junior Stock of the Corporation, an amount in cash equal to the
aggregate Junior Preferred Liquidation Value of all Junior Preferred Stock
outstanding to the date fixed for liquidation, dissolution or winding up. The
holders of Junior Preferred Stock will not be entitled to any further
payment. If, upon any such liquidation, dissolution or winding up of the
Corporation, the assets of the Corporation to be distributed among the
holders of Junior Preferred Stock are insufficient to permit payment to such
holders of the aggregate amount which they are entitled to be paid, then the
entire assets of the Corporation to be distributed to such holders will be
distributed ratably among such holders based upon the aggregate Junior
Preferred Liquidation Value of the Junior Preferred Stock held by each such
holder. The Corporation will mail written notice of such liquidation,
dissolution or winding up, not less than 30 days prior to the payment date
stated therein, to each record holder of Junior Preferred Stock. 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 Part 2 unless such consolidation,
merger, sale or transfer shall be in connection with a plan of liquidation,
dissolution or winding up of the business of the Corporation.

                                     -14-

Part 3. REDEMPTIONS.

        3A.  REDEMPTION AT THE OPTION OF THE CORPORATION.  Subject to the
legal availability of funds, any contractual restrictions then binding on the
Corporation (including restrictions under the Master Agreement) and
applicable state law, the Corporation may redeem at its option, at any time,
all or any portion of the Junior Preferred Stock then outstanding at a price
per share of Junior Preferred Stock equal to the Junior Preferred Redemption
Price.

        3B.  MANDATORY REDEMPTION.  Subject to the legal availability of
funds, any contractual restrictions then binding on the Corporation
(including restrictions under the Master Agreement) and applicable state law,
on the date upon which a holder of outstanding shares of Junior Preferred
Stock requests, by written notice to the Corporation, that the Corporation
redeem its Junior Preferred Stock, the Corporation will redeem all such
shares of Junior Preferred Stock at a price per share of Junior Preferred
Stock equal to the Junior Preferred Redemption Price.

        3C.  REDEMPTION PRICE.  For each share of Junior Preferred Stock
which is to be redeemed pursuant to this Part 3, the Corporation will be
obligated on (i) the date designated by the Corporation for redemption of
Preferred Stock in connection with Subpart 3A or (ii) the date any of the
events specified in Subpart 3B occur (each such date being herein referred to
as a "Junior Preferred Redemption Date" as further defined in Part 5) to pay
to the holder thereof (upon surrender by such holder at the Corporation's
principal office of the certificate representing such shares of Junior
Preferred Stock) an amount in cash equal to the Junior Preferred Redemption
Price. If the funds of the Corporation legally available for redemption of
Junior Preferred Stock on any Junior Preferred Redemption Date are
insufficient to redeem the total number of shares of Junior Preferred Stock
to be redeemed on such date, those funds which are legally available will be
used to redeem the maximum possible number of shares of Junior Preferred
Stock ratably among the holders of the Junior Preferred Stock to be redeemed.
At any time thereafter when additional funds of the Corporation are legally
available for the redemption of Junior Preferred Stock, such funds will
immediately be used to redeem the balance of the Junior Preferred Stock which
the Corporation has become obligated to redeem on any Junior Preferred
Redemption Date but which it has not redeemed.

        3D.  NOTICE OF REDEMPTION.  The Corporation will mail written notice
of each redemption of Junior Preferred Stock pursuant to subpart 3A or
Subpart 3B to each record holder thereof, not more than 60 nor less than 10
days prior to the date on which such redemption is to be made at such
holder's address as the same appears on the stock register of the Corporation;

                                     -15-
<Page>

PROVIDED, HOWEVER, that no failure to give such notice nor any defect therein
shall affect the validity of the proceeding for the redemption of any shares
of Junior Preferred Stock to be redeemed except as to the holder to whom the
Corporation has failed to give said notice or except as to the holder whose
notice was defective. Each such notice shall state: (i) the Junior Preferred
Redemption Date; (ii) the number of shares of Junior Preferred Stock to be
redeemed and, if less than all the shares held by such holder are to be
redeemed, the number of shares of Junior Preferred Stock held by such holder
to be redeemed; (iii) the Junior Preferred Redemption Price; (iv) the place
or places where certificates for such shares are to be surrendered for
payment of the Junior Preferred Redemption Price; and (v) that dividends on
the shares to be redeemed will cease to accrue on such Junior Preferred
Redemption Date. In case fewer than the total number of shares of Junior
Preferred Stock represented by any certificate are redeemed pursuant to this
Part 3, a new certificate representing the number of unredeemed shares of
Junior Preferred Stock will be issued to the holder thereof without cost to
such holder promptly after surrender of the certificate representing the
redeemed shares of Junior Preferred Stock.

        3E.  DETERMINATION OF THE NUMBER OF SHARES OF EACH HOLDER'S JUNIOR
PREFERRED STOCK TO BE REDEEMED.  The number of shares of Junior Preferred
Stock to be redeemed from each holder thereof in partial redemptions by the
Corporation under Subpart 3A will be the number of shares of Junior Preferred
Stock determined by multiplying the total number of shares of Junior
Preferred Stock desired to be redeemed times a fraction, the numerator of
which will be the total number of shares of Junior Preferred Stock then held
by such holder and the denominator of which will be the total number of
shares of Junior Preferred Stock then outstanding.

        3F.  DIVIDENDS AFTER REDEMPTION DATE.  No share of Junior Preferred
Stock is entitled to any dividends accruing after its Junior Preferred
Redemption Date. On such Junior Preferred Redemption Date all rights of the
holder of such share of Junior Preferred Stock will cease, and such share of
Junior Preferred Stock will not be deemed to be outstanding.

        3G. REDEEMED OR OTHERWISE ACQUIRED SHARES.  Any shares of Junior
Preferred Stock which are redeemed or otherwise acquired by the Corporation
or a subsidiary will be canceled and will not be reissued, sold or
transferred.

Part 4. VOTING RIGHTS.

        The outstanding shares of Junior Preferred Stock shall have no voting
rights except as required by law and such additional voting rights as are set
forth below.

                                       -16-
<Page>

        4A.  No amendment, modification or waiver will be binding or
effective with respect to any provision of Section B of Article Fourth of
this Restated Certificate of Incorporation unless approved by the affirmative
vote of the holders of at least a majority of the outstanding shares of
Junior Preferred Stock voting together as a separate class.

        4B.  In addition to any other vote or consent of stockholders
required herein, the By-laws of the Corporation or by law, the affirmative
vote of all the holders of the outstanding shares of Junior Preferred Stock,
voting together as a separate class, shall be necessary to change the rate or
time of payment of any dividends on, the time or amount of any redemption of,
or the amount of any payments upon liquidation of the Corporation with
respect to, the priorities afforded by the provisions of Subpart 1D for the
benefit of, shares of Junior Preferred Stock or to amend Part 3 of this Part
4.

        4C.  The affirmative vote of the holders of at least a majority of
the outstanding shares of Junior Preferred Stock voting together as a
separate class shall be necessary to:

                (i) except as provided by this Certificate of Incorporation,
        increase the number of authorized shares of Preferred Stock or Junior
        Preferred Stock or authorize or issue any additional shares of any
        series of Preferred Stock or Junior Preferred Stock or any shares of
        capital stock of the Corporation of any class, or any security or
        obligations convertible into any capital stock of the Corporation of
        any class, in each case ranking on a parity with or senior to the
        Junior Preferred Stock as to distribution of assets in liquidation
        or in right of payment of dividends;

               (ii) permit the sale, lease or conveyance of all or
        substantially all of the property or business of the Corporation or
        the consolidation or merger of the Corporation with or into any other
        corporation or the merger of another corporation into the Corporation
        unless in any of the circumstances set forth above the Corporation
        shall have exercised its option to redeem all of the shares of Junior
        Preferred Stock pursuant to Subpart 3A out of legally available
        funds; or

              (iii) change by amendment to the Corporation's Certificate of
        Incorporation or otherwise, the terms or provisions of the Junior
        Preferred Stock so as to adversely affect the powers, special rights
        and preferences of the holders thereof.

        4D.  If on any date a total of two annual dividends on the Junior
Preferred Stock have fully accrued but have not been paid in full (a "Junior
Preferred Dividend Arrearage") or if the

                                      -17-
<Page>

Corporation fails to make any redemption payment with respect to the Junior
Preferred Stock which it is obligated to make (a "Junior Preferred Redemption
Default"), the holders of shares of Junior Preferred Stock voting together as
a separate class, shall have the right to elect one director to the Board of
Directors from and after such election date. Such right of the holders of
Junior Preferred Stock to vote for the election of such director may be
exercised at any annual meeting or at any special meeting called for such
purpose as hereinafter provided or at any adjournment thereof, or by the
written consent, delivered to the Secretary of the Corporation, of the
holders of a majority of all outstanding shares of Junior Preferred Stock,
until all Junior Preferred Dividend Arrearages and Junior Preferred
Redemption Defaults shall have been paid in full (or such dividends or
redemptions declared or made and funds sufficient therefor set apart for
payment), at which time the term of office of the director so elected shall
terminate automatically. So long as such right to vote continues (and unless
such right has been exercised by written consent of the holders of a majority
of the outstanding shares of Junior Preferred Stock as hereinabove
authorized), the Secretary of the Corporation may call, and upon the written
request of the holders of record of a majority of the outstanding shares of
Junior Preferred Stock addressed to him at the principal office of the
Corporation shall call, a special meeting of the holders of such shares for
the election of such number of directors as provided herein. Such meeting
shall be held within 30 days after delivery of such request to the Secretary,
at the place and upon the notice provided by law and in the By-laws for the
holding of meetings of stockholders. No such special meeting or adjournment
thereof shall be held on a date less than 30 days before an annual meeting of
stockholders or any special meeting in lieu thereof. If at any such annual or
special meeting or any adjournment thereof the holders of a majority of the
then outstanding shares of Junior Preferred Stock entitled to vote in such
election shall be present or represented by proxy, or if the holders of a
majority of the outstanding shares of Junior Preferred Stock shall have acted
by written consent in lieu of a meeting with respect thereto, then the
authorized number of directors shall be increased by one director, and the
holders of the Junior Preferred Stock shall be entitled to elect such
director. The director so elected shall serve until the next annual meeting
or until his or her successor shall be elected and shall qualify, unless the
term of office of the person so called as director shall have terminated
under the circumstances set forth in the second sentence of this Subpart 4D.
If the director so elected by the holders of Junior Preferred Stock as a
class shall cease to serve as a director before his or her term shall expire,
the holders of the Junior Preferred Stock then outstanding and entitled to
vote for such director may, by written consent as hereinabove provided, or at
a special meeting of such holders called as provided above, elect a


                                      -18-
<Page>

successor to hold office for the unexpired term of the director whose place
shall be vacant.

so paid in full, the Junior Preferred Redemption Date will be the date on
which such Junior Preferred Redemption Price is fully paid as permitted and
required by this Section B of Article Fourth.

Upon the surrender of any certificate representing shares of Junior
Preferred Stock at such place, the Corporation shall, at the request of
the registered holder of such certificate, execute and deliver a new

the surrendered certificate (and the Corporation forthwith shall cancel
such surrendered certificate), subject to the requirements of applicable
securities laws and to any restrictions on transfer (including without
limitation, those referred to in any legend on the certificate so
surrendered). Each such new certificate shall be registered in such name
and shall represent such number of shares of Junior Preferred Stock as
is requested by the holder of the surrendered certificate and shall be
substantially identical in form to the surrendered certificate. The
issuance of new certificates shall be made without charge to the holders
of the surrendered certificates for any issuance tax in respect thereof
or other cost incurred by the Corporation in connection with such
issuance; PROVIDED, HOWEVER, that the Corporation shall not be required
to pay any tax which may be payable in respect of any transfer involved
in the issuance and delivery of any certificate in a name other than
that of the holder of the surrendered certificate.

or, in the case of any such mutilation, upon surrender of such certificate,
the Corporation shall (at its expense) execute and deliver in lieu of such
certificate a new certificate of like kind representing the number of shares
of Junior Preferred Stock represented by such lost, stolen,

                             D. ISSUANCE OF STOCK

         Except as otherwise provided in this Certificate of Incorporation,
the Board of Directors shall have authority to authorize the issuance, from
time to time, without any vote or other action by the stockholders, of any or
all shares of stock of the Corporation of any class or series at any time
authorized, and any securities convertible into or exchangeable for any such
shares, and any options, rights or warrants to purchase or acquire any such
shares, in each case to such persons and on such terms (including as a
dividend or distribution on or with respect to, or in connection with a split
or combination of, the outstanding shares of stock of the same or any other
class or series) as the Board of Directors from time to time in its


                                     -21-
<Page>

discretion lawfully may determine. Shares so issued shall be fully paid
stock, and the holders of such stock shall not be liable to any further call
or assessments thereon.

         FIFTH:  The following additional provisions are inserted for the

Corporation, and for the creation, definition, limitation and regulation of
the powers of the Corporation, the directors and the stockholders:

         1.  Election of directors need not be by written ballot. The Board
of Directors shall have power to make, alter, amend and repeal the By-Laws of
the Corporation and to fix the compensation of directors for services in any
capacity.

         2.  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, except for liability (a) for any breach of the
director's duty of loyalty to the Corporation or its stockholders, (b) for
acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (c) under Section 174 of the General
Corporation Law of the State of Delaware or (d) for any transaction from
which the director derived an improper personal benefit.

         Any repeal or modification of the foregoing paragraph 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.

         SIXTH:  The Corporation shall indemnify any person who was or is 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, including an action by or in the right of the Corporation,
by reason of the fact that he, or the person whose legal representative he
is, (1) is or was a stockholder, director, officer, employee or agent of the
Corporation (including the incorporator thereof), or (2) is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
or (3) is or was a director, officer or employee of the Corporation serving
at the request of the Corporation as a fiduciary of an employee benefit plan
or trust maintained for the benefit of employees of the Corporation or
employees of any such other enterprise, partnership, joint venture, trust, or
other enterprise, against judgments, fines, penalties, amounts paid in
settlement, and expenses, including attorneys' fees, actually and reasonably
incurred by him and the person whose legal representative he is, in
connection with such action, suit or


                                     -22-
<Page>

proceeding, or any appeal therein, to the fullest extent permitted by law.

         Expenses which may be indemnifiable under this Section incurred in
defending an action, suit or proceedings may be paid by the Corporation in
advance of the final disposition of such action, suit or proceeding as
authorized by the Board of Directors upon agreement by or on behalf of the
stockholder, director, officer, employee or agent, or his legal
representative, to repay such amount if he is later found not entitled to be
indemnified by the Corporation as authorized in this Article Sixth.

         The Corporation shall not indemnify any stockholder, director,
officer, employee or agent against judgments, fines, amounts paid in
settlement and expenses, including attorneys' fees, to an extent greater than
that authorized by this Article Sixth, but the Corporation may procure
insurance providing greater indemnification and may share the premium cost
with any stockholder, director, officer, employee or agent on such basis as
may be agreed upon.

         Rose Marie Williams, being the Secretary of NAMSCO Inc., a
corporation duly organized and existing under and by virtue of the General
Corporation Law of the State of Delaware (the "Corporation"), does hereby
certify as follows:

         FIRST:   That the Certificate of Incorporation of the Corporation
be, and hereby is, amended by deleting Paragraph 1B of Part One of Section C
of Article Fourth in its entirety and substituting in lieu thereof a new
Paragraph 1B of Part One of Section C of Article Fourth to read as follows:

                  C. COMMON STOCK
                  Part 1. VOTING RIGHTS.
                  1B. ELECTION OF DIRECTORS. The number of directors which
                  shall constitute the Board of Directors shall be not less
