     (whether by merger, consolidation or otherwise) by the Corporation or any
     of its Subsidiaries after the Closing Date and prior to the second
     anniversary of the Closing Date, would result in the fair market value of
     the aggregate consideration to be received with respect thereto (as
     determined in good faith by the Board of Directors of the Corporation) to
     equal or exceed $2,000,000.

     holders of the Class A Common shall be distributed ratably, based upon the
     number of outstanding shares of Class A Common held by each such holder,
     and shall be designated first as payment of Yield on and then as a return
     of Original Cost of the Onex Potential Loss Investments.

          (v) Following the distributions described in Section 2A(iv) above, (A)

     (ii) Except as provided in Sections 2A and 2B above and in this Section 2D,
the holders of Class G Common shall not be entitled to receive distributions
made to holders of Common Stock, whether in cash, property, or securities of the
Corporation and whether by dividend, liquidating distributions or otherwise.

     2E. Treatment of Class B Common, Class C Common, Class D Common, Class F
Common or Class I Common Upon Certain Transfers. Upon a transfer of any shares
of Class B Common, Class C Common, Class D Common, Class F Common or Class I
Common (x) on or after the third anniversary of the Closing Date or (y) as a
part of a Sale of the Company, the shares of Class B Common, Class C Common,
Class D Common, Class F Common or Class I Common, as the case may be, so
transferred shall no longer be subject to or governed by the provisions of
Section 2B and, without further action on the part of such holder, shall
thereafter be governed by the provisions of Section 2C as it, for all purposes
of this Part 2, the shares so transferred were shares of Class E Common, Class H
Common or Class J Common.

     Part 3. Conversion.

     3A. Conversion of Class B Common. Each record holder of Class B Common
shall be entitled at any time, if such holder has or is reasonably expected to
have a Regulatory Problem, to convert any or all of the shares of such holder's
Class B Common into the same number of shares of Class F Common. For purposes of
this paragraph 3A, a holder will be deemed to have a "Regulatory Problem" when
such holder and such holder's affiliates would own, control or have power over a
greater quantity of securities of any kind issued by the Corporation than is
permitted under any applicable requirement of any governmental authority, or
would not be able to hold an investment or provide financing to the Corporation
in compliance with any applicable requirement of any governmental authority.

     3B. Conversion of Class F Common.

     (i) Upon the occurrence (or the expected occurrence as described in (iii)
below) of any Conversion Event, each holder of Class F Common shall be entitled
to convert into the same number of shares of Class B Common any or all of the
shares of such holder's Class F Common being (or expected to be) distributed,
disposed of or sold in connection with such Conversion Event.

     (ii) For purposes of this Section 3B, a "Conversion Event" shall mean (a)
any public offering or public sale of securities of the Corporation (including a
public offering regis-



                                      -7-


tered under the Securities Act of 1933 and a public sale pursuant to Rule 144 of
the Securities and Exchange Commission or any similar rule then in force), (b)
any sale of securities of the Corporation to a person or group of persons
(within the meaning of the Securities Exchange Act of 1934, as amended (the
"1934 Act")) if, after such sale, such person or group of persons in the
aggregate would own or control securities which possess in the aggregate the
ordinary voting power to elect a majority of the Corporation's directors
(provided that such sale has been approved by the Corporation's Board of
Directors or a committee thereof), (c) any sale of securities of the Corporation
to a person or group of persons (within the meaning of the 1934 Act) if, after
such sale, such person or group of persons in the aggregate would own or control
securities of the Corporation (excluding any Class F Common being converted and
disposed of in connection with such Conversion Event) which possess in the
aggregate the ordinary voting power to elect a majority of the Corporation's
directors, (d) any sale of securities of the Corporation to a person or group of
persons (within the meaning of the 1934 Act) if, after such sale, such person or
group of persons would not, in the aggregate, own, control or have the right to
acquire more than two percent (2%) of the outstanding securities of any class of
voting securities of the Corporation, and (e) a merger, consolidation or similar
transaction involving the Corporation if, after such transaction, a person or
group of persons (within the meaning of the 1934 Act) in the aggregate would own
or control securities which possess in the aggregate the ordinary voting power
to elect a majority of the surviving corporation's directors (provided that the
transaction has been approved by the Corporation's Board of Directors or a
committee thereof). For purpose of this Section 3B, "person" shall include any
natural person and any corporation, partnership, joint venture, trust,
unincorporated organization and any other entity or organization.

     (iii) Each holder of Class F Common shall be entitled to convert shares of
Class F Common in connection with any Conversion Event if such holder reasonably
believes that such Conversion Event will be consummated, and a written request
for conversion from any holder of Class F Common to the Corporation stating such
holder's reasonable belief that a Conversion Event shall occur shall be
conclusive and shall obligate the Corporation to effect such conversion in a
timely manner so as to enable each such holder to participate in such Conversion
Event. The Corporation will not cancel the shares of Class F Common so converted
before the tenth day following such Conversion Event and will reserve such
shares until such tenth day for reissuance in compliance with the next sentence.
If any shares of Class F Common are converted into shares of Class B Common in
connection with a Conversion Event and such shares of Class B Common are not
actually distributed, disposed of or sold pursuant to such Conversion Event,
such shares of Class B Common shall be promptly converted back into the same
number of shares of Class F Common.

     3C. Conversion Procedure.

     (i) Unless otherwise provided in connection with a Conversion Event with
respect to the Class F Common, each conversion of shares of one class of Common
Stock into shares of the other class of Common Stock shall be effected by the
surrender of the certificate or certificates representing the shares to be
converted at the principal office of the Corporation at any time during normal
business hours, together with a written notice by the holder of such Common
Stock stating that such holder desires to convert the shares, or a stated number
of the shares, of such Common Stock represented by such certificate or
certificates into shares of the



                                      -8-


other class of Common Stock. Unless otherwise provided in connection with a
Conversion Event, each conversion shall be deemed to have been effected as of
the close of business on the date on which such certificate or certificates have
been surrendered and such notice has been received, and at such time the rights
of the holder of the converted Class F Common or Class B Common, as the case may
be, as such holder shall cease and the person or persons in whose name or names
the certificate or certificates for shares of Class B Common or Class F Common
are to be issued upon such conversion shall be deemed to have become the holder
or holders of record of the shares of Class B Common or Class F Common
represented thereby.

     (ii) Promptly after the surrender of certificates and the receipt of
written notice, the Corporation shall issue and deliver in accordance with the
surrendering holder's instructions (a) the certificate or certificates for the
Class B Common or Class F Common issuable upon such conversion and (b) a
certificate representing any Class F Common or Class B Common which was
represented by the certificate or certificates delivered to the Corporation in
connection with such conversion but which was not converted.

     (iii) The issuance of certificates for Class B Common upon conversion of
Class F Common and for Class F Common upon conversion of Class B Common will be
made without charge to the holders of such shares for any issuance tax in
respect thereof or other cost incurred by the Corporation in connection with
such conversion and the related issuance of Class B Common or Class F Common, as
the case may be.

     (iv) The Corporation shall at all times reserve and keep available out of
its authorized but unissued shares of Class B Common and Class F Common, solely
for the purpose of issuance upon the conversion of the Class F Common and Class
B Common, respectively, such number of shares of Class F Common and Class B
Common issuable upon the conversion of all outstanding Class B Common and Class
F Common, as the case may be. All shares of Common Stock which are so issuable
shall, when issued, be duly and validly issued, fully paid and nonassessable and
free from all taxes, liens and charges. The Corporation shall take all such
actions as may be necessary to assure that all such shares of Common Stock may
be so issued without violation of any applicable law or governmental regulation
or any requirements of any domestic securities exchange upon which shares of
Common Stock may be listed (except for official notice of issuance, which will
be immediately transmitted by the Corporation upon issuance).

     (v) The Corporation shall not close its books against the transfer of
shares of Common Stock in any manner which would interfere with the timely
conversion of any shares of Common Stock.

     3D. Regulated Holders.

     (i) The Corporation shall not be a party to any merger, consolidation or
recapitalization pursuant to which any Regulated Stockholder (as defined in
subsection (iii) below) would be required to take (a) any voting securities
which would cause such holder to hold more than 4.99% of the outstanding shares
of any "class" of voting securities, or (b) any securities convertible into
voting securities which if such conversion took place would cause such holder to
hold more than 4.99% of the outstanding shares of any "class" of voting
securities other than securities which are specifically provided to be
convertible only in the event that such conversion



                                      -9-


may occur without any violation of Regulation Y (as defined below), provided
that each such Regulated Stockholder shall convert or take such other action
(which action does not adversely affect such Regulated Stockholder) with respect
to the Common Stock it owns, controls or has the power to vote in order to
permit the Corporation to consummate any such merger, consolidation or
recapitalization. The term "class" shall be determined by reference to
Regulation Y of the Board of Governors of the Federal Reserve System (12 C.F.R.
Part 225), or any successor to such regulation ("Regulation Y") and all
authoritative interpretations of Regulation Y.

     (ii) The Corporation shall not convert or directly or indirectly redeem,
purchase or otherwise acquire any shares of capital stock of the Corporation or
take any other action affecting the voting rights of such shares, if such action
will increase the percentage of any class of outstanding voting securities owned
or controlled by any Regulated Stockholder (other than any such stockholder
which requested that the Corporation take such action, or which otherwise waives
in writing its rights under this subsection (ii)) to more than 4.99% of the
outstanding shares of such voting securities, unless the Corporation gives
written notice (the "Deferral Notice") of such action to each Regulated
Stockholder. The Corporation will defer making any such conversion, or taking
any such other action for a period of 30 days (the "Deferral Period") after
giving the Deferral Notice in order to allow each Regulated Stockholder to
convert or take any other action with respect to the Common Stock it owns,
controls or has the power to vote in order to permit the Corporation to
consummate any such conversion or other action specified in the Deferral Notice
without violating this Section 3D. Each such Regulated Stockholder shall convert
or take such other action (which action does not adversely affect such Regulated
Stockholder) with respect to the Common Stock it owns, controls or has the power
to vote in order to permit the Corporation to consummate any such conversion or
other action without violating this Section 3D and shall notify the Corporation
in writing within 20 days of the issuance of the Deferral Notice of the
conversion or other action to be taken with respect to such Shares of Common
Stock. Thereupon, the Corporation shall (i) defer taking the pending action
until the end of the Deferral Period, (ii) promptly notify from time to time
each other Regulated Stockholder holding shares of such proposed conversion and
the proposed transactions, and (iii) effect the conversions requested by all
Regulated Stockholders in response to the notices issued pursuant to this
subsection (ii) at the end of the Deferral Period. The Corporation will not
directly or indirectly redeem, purchase, acquire or take any other action
affecting outstanding shares of Common Stock if such action will increase above
24.9% the percentage of outstanding Common Stock owned or controlled by any
Regulated Stockholder and its affiliates (other than a stockholder which waives
in writing its rights under this subsection (ii)), provided that each such
Regulated Stockholder shall convert or take such other action (which action does
not adversely affect such Regulated Stockholder) with respect to the Common
Stock it owns, controls or has the power to vote in order to permit the
Corporation to consummate any such conversion or other action without violating
this Section 3D.

     (iii) As used herein, the term "Regulated Stockholder" shall mean any
stockholder that is subject to the provisions of Regulation Y or any successor
to such regulation, provided that, except in the case of Chemical Equity
Associates, a California Limited Partnership, such stockholder gives the
Corporation written notice that it is subject to such provisions of Regulation
Y.



                                      -10-


     3E. Amendment and Waiver. Notwithstanding anything to the contrary herein,
no amendment or waiver of any provision of this Part 3 shall be effective
without the prior approval of the holders of a majority of the then outstanding
Class B Common voting as a separate class.

     Part 4. Stock Splits and Stock Dividends.

     The Corporation shall not in any manner subdivide (by stock split, stock
dividend or otherwise), or combine (by stock split, stock dividend or otherwise)
the outstanding Common Stock of one class unless the outstanding Common Stock of
all the other classes shall be proportionately subdivided or combined. All such
subdivisions and combinations shall be payable only in shares of the same class
of Common Stock held by a holder of Common Stock. In no event shall a stock
split or stock dividend be designated as a payment of Yield or a return of
Original Cost.

     Part 5. Registration of Transfer.

     The Corporation shall keep at its principal office (or such other place as
the Corporation reasonably designates) a register for the registration of shares
of Common Stock. Upon the surrender of any certificate representing shares of
any class of Common Stock at such place, the Corporation shall, at the request
of the registered holder of such certificate, execute and deliver a new
certificate or certificates in exchange therefor representing in the aggregate
the number of shares of such class represented by the surrendered certificate,
and the Corporation forthwith shall cancel such surrendered certificate. Each
such new certificate will be registered in such name and will represent such
number of shares of such class 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.

     Part 6. Replacement.

     Upon receipt of evidence reasonably satisfactory to the Corporation (an
affidavit of the registered holder will be satisfactory) of the ownership and
the loss, theft, destruction or mutilation of any certificate evidencing one or
more shares of any class of Common Stock, and in the case of any such loss,
theft of destruction, upon receipt of indemnity reasonably satisfactory to the
Corporation (provided that if the holder is a financial institution or other
institutional investor its own agreement will be satisfactory), 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 such class
represented by such lost, stolen, destroyed or mutilated certificate and dated
the date of such lost, stolen, destroyed or mutilated certificate.

     Part 7. Notices.

     All notices referred to herein shall be dated and in writing, to the
Corporation at its principal executive offices and to any stockholder at such
holder's address as it appears in the



                                      -11-


stock records of the Corporation (unless otherwise specified in a written notice
to the Corporation by such holder), and shall be deemed to have been given (i)
when delivered, if delivered personally, sent by confirmed telecopy or certified
mail, return receipt requested, postage prepaid, (ii) on the next business day
if sent by overnight courier and (iii) when received if delivered otherwise.

     Part 8. Amendment and Waiver.

     No amendment or waiver of any provision of this Article Fourth (including,
without limitation, any merger, consolidation or other transaction subject to
stockholder approval in which any class of Common Stock is treated differently
from any other class in a manner not contemplated by this Article Fourth) shall
be effective without the prior written consent of the holders of a majority of
the then outstanding shares of each class of Common Stock voting as a separate

                                                                       EXHIBIT A


                      RESTATED CERTIFICATE OF INCORPORATION
                                       OF
                       JOHNSTOWN AMERICA INDUSTRIES, INC.


     FIRST: The name of the corporation is Johnstown America Industries, Inc.
(hereinafter the "Corporation").

     SECOND: The address of the registered office of the Corporation in the
State of Delaware is 1209 Orange Street, in the City of Wilmington, County of
New Castle. The name of its registered agent at that address is The Corporation
Trust Company.

     THIRD: The purpose of the corporation is to engage in any lawful act or
activity for which a corporation may be organized under the General Corporation
Law of the State of Delaware as set forth in Title 8 of the Delaware Code (the
"GCL").

     FOURTH: The total number of shares of stock which the Corporation shall
have the authority to issue is 221,000,000 shares consisting of 200,000,000
shares of common stock with a par value of $.01 per share (the "Common Stock"),
1,000,000 shares of Class B Common Stock with a par value of $.01 per share (the
"Class B Common Stock"), and 20,000,000 shares of preferred stock with a par
value of $.01 per share (the "Preferred Stock").

     I. Common Stock and Class B Common Stock. Except as otherwise provided in
this Article Fourth or as otherwise required by applicable law, shares of Common
Stock and Class B Common Stock shall be identical and shall entitle the holders
thereof to the same rights and privileges, subject to the same qualifications,
limitations and restrictions.

     (a) Voting Rights. Except as otherwise provided in this Article Fourth or
as otherwise required by applicable law, holders of Common Stock shall be
entitled to one vote per share on all matters to be voted on by the
Corporation's stockholders and holders of shares of Class B Common Stock shall
have no voting rights.

     (b) Conversion Rights. Each record holder of Common Stock shall be entitled
at any time, if such holder has or is reasonably expected to have a Regulatory
Issue, to convert any or all of the shares of such holder's Common Stock into
the same number of shares of Class B Common Stock. For purposes of this
paragraph, a holder will be deemed to have a "Regulatory Issue" when such holder
and such holder's affiliates would own, control or have power over a greater
quantity of securities of any kind issued by the Corporation than is permitted
under any applicable requirement of any governmental authority, or would not be
able to hold an investment or provide financing to the Corporation in compliance
with any applicable requirement of any governmental authority.

     Upon the occurrence (or the expected occurrence as described in the next
paragraph) of any Conversion Event, each record holder of Class B Common Stock
shall be entitled to convert into the same number of shares of Common Stock any
or all of the shares of such





holder's Class B Common Stock being (or expected to be) distributed, disposed of
or sold in connection with the occurrence (or the expected occurrence as
described below) of a Conversion Event. For purposes of this paragraph, a
"Conversion Event" shall mean (i) any public offering or public sale of
securities of the Corporation (including a public offering registered under the
Securities Act of 1933 and a public sale pursuant to Rule 144 of the Securities
and Exchange Commission or any similar rule then in force), (ii) any sale of
securities of the Corporation to a person or group of persons (within the
meaning of the Securities Exchange Act of 1934, as amended (the "1934 Act")) if,
after such sale, such person or group of persons in the aggregate would own or
control securities which possess in the aggregate the ordinary voting power to
elect a majority of the Corporation's directors (provided that such sale has
been approved by the Corporation's Board of Directors (the "Board of Directors")
or a committee thereof), (iii) any sale of securities of the Corporation to a
person or group of persons (within the meaning of the 1934 Act) if, after such
sale, such person or group of persons in the aggregate would own or control
securities of the Corporation (excluding any Class B Common Stock being
converted and disposed of in connection with such Conversion Event) which
possess in the aggregate the ordinary voting power to elect a majority of the
Corporation's directors, (iv) any sale of securities of the Corporation to a
person or group of persons (within the meaning of the 1934 Act) if, after such
sale, such person or group of persons would not, in the aggregate, own, control
or have the right to acquire more than two percent (2%) of the outstanding
securities of any class of voting securities of the Corporation, and (v) a
merger, consolidation or similar transaction involving the Corporation if, after
such transaction, a person or group of persons (within the meaning of the 1934
Act) in the aggregate would own or control securities which possess in the
aggregate the ordinary voting power to elect a majority of the surviving
corporation's directors (provided that the transaction has been approved by the
Board of Directors or a committee thereof). For purpose of this paragraph,
"person" shall include any natural person and any corporation, partnership,
joint venture, trust, unincorporated organization and any other entity or
organization.

     Each record holder of Class B Common Stock shall also be entitled to
convert shares of Class B Common Stock in connection with any Conversion Event
if such holder reasonably believes that such Conversion Event will be
consummated, and a written request for conversion from any holder of Class B
Common Stock to the Corporation stating such holder's reasonable belief that a
Conversion Event will occur shall be conclusive and shall obligate the
Corporation to effect such conversion in a timely manner so as to enable each
such holder to participate in such Conversion Event. The Corporation will not
cancel the shares of Class B Common Stock so converted before the tenth day
following such Conversion Event and will reserve such snares until such tenth
day for reissuance in compliance with the next sentence. If any shares of Class
B Common Stock are converted into shares of Common Stock in connection with a
Conversion Event and such shares of Common Stock are not actually distributed,
disposed of or sold pursuant to such Conversion Event, such shares of Common
Stock shall be promptly converted back into the same number of shares of Class B
Common Stock.

     Unless otherwise provided in connection with a Conversion Event, each
conversion of shares of one class of common stock into shares of the other class
of common stock shall be effected by the surrender of the certificate or
certificates representing the shares to be converted at the principal office of
the Corporation at any time during normal business hours, together with a
written notice by the holder of such common stock stating that such holder
desires



                                      -2-


to convert the shares, or a stated number of the shares, of such common stock
represented by such certificate or certificates into shares of the other class
of common stock. Unless otherwise provided in connection with a Conversion
Event, each conversion shall be deemed to have been effected as of the close of
business on the date on which such certificate or certificates have been
surrendered and such notice has been received, and at such time the rights of
the holder of the converted Common Stock or Class B Common Stock, as the case
may be, as such holder shall cease and the person or persons in whose name or
names the certificate or certificates for shares are to be issued upon such
conversion shall be deemed to have become the holder or holders of record of the
shares represented thereby. Promptly after the surrender of certificates and the
receipt of written notice, the Corporation shall issue and deliver in accordance
with the surrendering holder's instructions (a) the certificate or certificates
for the shares issuable upon such conversion and (b) a certificate representing
any shares which were represented by the certificate or certificates delivered
to the Corporation in connection with such conversion but which were not
converted. The issuance of certificates upon conversion will be made without
charge to the holders of such shares for any issuance tax in respect thereof or
other cost incurred by the Corporation in connection with such conversion.

     The Corporation shall at all times reserve and keep available out of its
authorized but unissued shares of Common Stock solely for the purpose of
issuance upon the conversion of the Class B Common Stack, such number of shares
of Common Stock issuable upon the conversion of all outstanding Class B Common
Stock. All shares of Common Stock which are so issuable shall, when issued, be
duly and validly issued, full paid and nonassessable and free from all taxes,
liens and charges. The Corporation shall take all such actions as may be
necessary to assure that all such shares of Common Stock may be so issued
without violation of any applicable law or governmental regulation or any
requirements of any domestic securities exchange upon which shares of Common
Stock may be listed (except for official notice of issuance which will be
immediately transmitted by the Corporation upon issuance). The Corporation shall
not close its books against the transfer of shares in an manner which would
interfere with the timely conversion of any shares.

     The Corporation shall not be a party to any merger, consolidation or
recapitalization pursuant to which any Regulated Stockholder (as defined in the
following paragraph) would be required to take (a) any voting securities which
would cause such holder to hold more than 4.99% of the outstanding shares of any
"class" of voting securities, or (b) any securities convertible into voting
securities which if such conversion took place would cause such holder to hold
more than 4.99% of the outstanding shares of any "class" of voting securities
other than securities which are specifically provided to be convertible only in
the event that such conversion may occur without any violation of Regulation Y
(as defined below), provided that each such Regulated Stockholder shall convert
or take such other action (which action does not adversely affect such Regulated
Stockholder) with respect to the common stock it owns, controls or has the power
to vote in order to permit the Corporation to consummate any such merger,
consolidation or recapitalization. The term "class" shall be determined by
reference to Regulation Y of the Board of Governors of the Federal Reserve
System (12 C.F.R. Part 225), or any successor to such regulation ("Regulation
Y") and all authoritative interpretations of Regulation Y. The Corporation shall
not convert or directly or indirectly redeem, purchase or otherwise acquire any
shares of capital stock of the Corporation or take any other action affecting
the voting rights of



                                      -3-


such shares, if such action will increase the percentage of any class of
outstanding voting securities owned or controlled by any Regulated Stockholder
(other than any such stockholder which has requested that the Corporation take
such action, or which otherwise waives in writing its rights hereunder to more
then 4.99% of the outstanding shares of such voting securities), unless the
Corporation gives written notice (the "Deferral Notice") of such action to each
Regulated Stockholder. The Corporation will defer making any such conversion or
taking any such other action for a period of 30 days (the "Deferral Period")
after giving the Deferral Notice in order to allow each Regulated Stockholder to
convert or take any other action with respect to the common stock it owns,
controls or has the power to vote in order to permit the Corporation to
consummate any such conversion or other action specified in the Deferral Notice
without violating this paragraph. Each such Regulated Stockholder shall convert
or take such other action (which action does not adversely affect such Regulated
Stockholder) with respect to the common stock it owns, controls or has the power
to vote in order to permit the Corporation to consummate any such conversion or
other action without violating this paragraph and shall notify the Corporation
in writing within 20 days of the issuance of the Deferral Notice of the
conversion or other action to be taken with respect to such shares of common
stock. Thereupon, the Corporation shall (i) defer taking the pending action
until the end of the Deferral Period, (ii) promptly notify from time to time
each other Regulated Stockholder holding shares of each proposed conversion and
the proposed transactions, and (iii) effect the conversions requested by all
Regulated Stockholders in response to the notices issued pursuant to this
paragraph at the end of the Deferral Period. The Corporation will not directly
or indirectly redeem, purchase, acquire or take any other action affecting
outstanding shares of common stock if such action will increase above 24.9% the
percentage of outstanding common stock owned or controlled by any Regulated
Stockholder and its affiliates (other than a stockholder which waives in writing
its rights under this paragraph), provided that each such Regulated Stockholder
shall convert or take such other action (which action does not adversely affect
such Regulated Stockholder) with respect to the common stock it owns, controls
or has the power to vote in order to permit the Corporation to consummate any
such conversion or other action without violating this paragraph.

     As used herein, the term "Regulated Stockholder" shall mean any stockholder
that is subject to the provision of Regulation Y or any successor to such
regulation, provided that, except in the case of Chemical Equity Associates, a
California Limited Partnership, such stockholder gives the Corporation written
notice that it is subject to such provisions of Regulation Y.

     Notwithstanding anything to the contrary herein, no amendment or waiver of
any provision pertaining to the conversion rights of the Common Stock and Class
B Common Stock shall be effective without the prior approval of the holders of a
majority of the then outstanding Class B Common stock voting as a separate
class.

     II. Preferred Stock. Shares of the Preferred Stock of the Corporation may
be issued from time to time in one or more classes or series, each of which
class or series shall have such distinctive designation or title as shall be
fixed by the Board of Directors prior to the issuance of any shares thereof.
Each such class or series of Preferred Stock shall have such voting powers, full
or limited, or no voting powers, and such preferences and relative,
participating, optional or other special rights and such qualifications,
limitations or restrictions thereof as shall be stated in such resolution or
resolutions providing for the issue of such class or series of Preferred



                                      -4-


Stock as may be adopted from time to time by the Board of Directors prior to the
issuance of any shares thereof pursuant to the authority hereby expressly vested
in it, all in accordance with the laws of the State of Delaware.

     FIFTH: The business and affairs of the Corporation shall be managed by or
under the direction of the Board of Directors. The number of directors of the
Corporation shall be not less than three nor more than nine, the exact number to
be fixed from time to time by the Board of Directors. A director shall hold
office until the annual meeting for the year in which his term expires and until
his successor shall be elected and shall be qualified, subject, however, to
prior death, resignation, retirement, disqualification or removal from office.

     SIXTH: At the earlier of (x) such time as Onex U.S. Investments Inc., an
Ontario corporation ("Onex"), has sold or otherwise transferred in one or more
transactions to any persons or entities other than Affiliates (as hereinafter
defined) of Onex 50% or more of (i) the 2,308,450 shares of Common Stock held by
it after consummation of the initial public offering (the "Offering") of shares
of Common Stock or (ii) if the over-allotment option granted to the underwriters
in connection with the Offering is exercised, the 2,017,500 shares of Common
Stock held by it after exercise of such over-allotment option or (y) such time
as Onex has given its consent in writing to the Corporation, and without any
further action by the Corporation, the Board of Directors or the Corporation's
stockholders, the provisions of this Article Sixth shall become and thereafter
shall remain effective. The number of shares referred to in clauses (x) and (y)
of the previous sentence shall be adjusted to reflect any stock split or other
amendments to, or reclassifications of, the capital stock of the Corporation.
The Board of Directors shall be divided into three classes, designated Class I,
Class II and Class III, with each class consisting, as nearly as may be
possible, of one-third of the total number of directors constituting the entire
Board of Directors. The then chairman of the Board of the Corporation shall
designate the initial class of each director. The term of the initial Class I
directors shall terminate on the date of the first annual meeting of
stockholders thereafter; the term of the initial Class II directors shall
terminate on the date of the second annual meeting of stockholders thereafter;
and the term of the initial Class III directors shall terminate on the date of
the third annual meeting of stockholders thereafter. At the first annual meeting
of stockholders after the Board of Directors has been divided into classes and
at each annual meeting of stockholders thereafter, successors to the class of
directors whose term expires at that annual meeting shall be elected for a
three-year term. If the number of directors is changed, any increase or decrease
shall be apportioned among the classes so as to maintain the number of directors
in each class as nearly equal as possible, and any additional directors of any
class elected to fill a vacancy resulting from an increase in such class shall
hold office for a term that shall coincide with the remaining term of that
class, but in no case will a decrease in the number of directors shorten the
term of any incumbent director. Any vacancy on the Board of Directors, howsoever
resulting, may be filled only by a majority of the directors then in office,
even if less than a quorum, or by a sole remaining director. Any director
elected to fill a vacancy shall hold office for a term that shall coincide with
the term of the class to which such director shall have been elected. Any or all
of the directors of the Corporation may be removed from office at any time, but
only for cause and only by the affirmative vote of the holders of a majority of
the outstanding shares of stock of the Corporation then entitled to vote
generally in the election of directors.



                                      -5-


     For purposes of this Restated Certificate of Incorporation, the term
"Affiliate" shall mean, with respect to any person, any of (a) a director or
executive officer of such person, (b) a spouse, parent, sibling or descendant of
such person (or a spouse, parent, sibling or descendant of any director or
executive officer of such person), and (c) any other person that, directly or
indirectly, controls or is controlled by or is under common control with such
person. For the purpose of this definition, "control" (including the terms
"controlling", "controlled by" and "under common control with"), as used with
respect to any person, shall mean the possession, directly or indirectly, of the
power to direct or cause the direction of the management or policies of such
person, whether through the ownership of voting securities or by contract or
agency or otherwise.

     SEVENTH: At the earlier of (x) such time as Onex has sold or otherwise
transferred in one or more transactions to any persons or entities other than
Affiliates of Onex 50% or more of (i) the 2,308,450 shares of Common Stock held
by it after consummation of the Offering or (ii) if the over-allotment option
granted to the underwriters in connection with the Offering is exercised, the
2,017,500 shares of Common Stock held by it after exercise of such
over-allotment option or (y) such time as Onex has given its consent in writing
to the Corporation, and without any further action by the Corporation, the Board
of Directors or the Corporation's stockholders, the provisions of this Article
Seventh shall become and thereafter shall remain effective. The number of shares
referred to in clauses (x) and (y) of the previous sentence shall be adjusted to
reflect any stock split or other amendments to, or reclassifications of, the
capital stock of the Corporation. Special meetings of stockholders of the
Corporation for any purpose or purposes may be called at any time by a majority
of the Board of Directors, the Chairman of the Board of Directors or the
President of the Corporation. Special meetings of the stockholders of the
Corporation may not be called by any other person or persons. Any action
required or permitted to be taken at any annual or special meeting of
stockholders may be taken only upon the vote of the stockholders at an annual or
special meeting duly noticed and called, as provided in the By-laws of the
Corporation, and may not be taken by a written consent of the stockholders
pursuant to the GCL.

     EIGHTH: No director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for any breach of fiduciary
duty by such a director as a director. Notwithstanding the foregoing sentence, a
director shall be liable to the extent provided by applicable law (i) for any
breach of the director's duty of loyalty to the Corporation or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the
GCL or (iv) for any transaction from which the director derived an improper
personal benefit. No amendment to or repeal of this Article Eighth shall apply
to or have any effect on the liability or alleged liability of any director of
the Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment or repeal.

     NINTH: Meetings of the stockholders may be held within or without the State
of Delaware, as the By-laws may provide. The books of the Corporation may be
kept (subject to any provision contained in the GCL) outside of the State of
Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the By-laws of the Corporation.



                                      -6-


     TENTH: In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized to adopt, repeal, alter,
amend or rescind the By-laws of the Corporation; provided, however, that Article
IX of the By-laws shall be amended (i) only with the affirmative vote of the
holders of at least 80% of the outstanding shares of stock of the Corporation
then entitled to vote generally in the election of directors or (ii) by the
unanimous vote of the Board of Directors then in office.

     ELEVENTH: Except as contemplated by Article Twelfth, the affirmative vote
of the holders of at least 80% of the outstanding shares of stock of the
Corporation then entitled to vote generally in the election of directors shall
be required to amend Article Fifth, Sixth, Seventh, Eighth, Ninth, Tenth,
Eleventh or Twelfth of this Restated Certificate of Incorporation, other than
technical amendments.

     TWELFTH: Except as otherwise contemplated by the provisions of this
Restated Certificate of Incorporation, the Corporation reserves the right to
repeal, alter, amend, or rescind any provision contained in this Restated
Certificate of Incorporation, in the manner now or hereafter prescribed by
statute, and all rights conferred on stockholders herein are granted subject to
this reservation.

 Pursuant to Section 151 of the General Corporation Law of the State of Delaware


     The undersigned officer of Johnstown America Industries, Inc., a
corporation organized and existing under the General Corporation Law of the
State of Delaware, in accordance with the provisions of Section 103 thereof,
DOES HEREBY CERTIFY:

     That pursuant to the authority conferred upon the Board of Directors by the
Amended and Restated Certificate of Incorporation of the said Corporation, the
said Board of Directors on October 4, 1995, adopted the following resolution
creating a series of 20,000 shares of Preferred Stock designated as Series A
Junior Participating Preferred Stock:

     RESOLVED, that pursuant to the authority vested in the Board of Directors
of this Corporation in accordance with the provision of its Amended and Restated
Certificate of Incorporation, a series of Preferred Stock of the Corporation be
and it hereby is created, and that the designation and amount thereof and the
voting powers, preferences and relative, participating, optional and other
special rights of the shares of such series, and the qualifications, limitations
or restrictions thereof are as follows:

     Section 1. Designation and Amount. The shares of such series shall be
designated as "Series A Junior Participating Preferred Stock" and the number of
shares constituting such series shall be 20,000.

     Section 2. Dividends and Distributions.

     (A) The holders of shares of Series A Junior Participating Preferred Stock
shall be entitled to receive, when, as and if declared by the Board of Directors
out of funds legally available for the purpose, quarterly dividends payable in
cash on the last day of March, June, September and December in each year (each
such date being referred to herein as a "Quarterly Dividend Payment Date"),
commencing on the first Quarterly Dividend Payment Date after the first issuance
of a share or fraction of a share of Series A Junior Participating Preferred
Stock, in an amount per share (rounded to the nearest cent) equal to the greater
of (a) $0.01 or (b) subject to the provision for adjustment hereinafter set
forth, 1000 times the aggregate per share amount of all cash dividends, and 1000
times the aggregate per share amount (payable in kind) of all non-cash dividends
or other distributions other than a dividend payable in shares of Common Stock
or a subdivision of the outstanding shares of Common Stock (by reclassification
or otherwise), declared on the Common Stock, par value $0.01 per share, of the
Corporation (the "Common Stock") since the immediately preceding Quarterly
Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment
Date, since the first issuance of any share or fraction of a share of Series A
Junior Participating Preferred Stock. In the event the Corporation shall at any
time after October 4, 1995 (the "Rights Declaration Date") (i) declare any
dividend





on Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock, or (iii) combine the outstanding Common Stock into a
smaller number of shares, then in each such case the amount to which holders of
shares of Series A Junior Participating Preferred Stock were entitled
immediately prior to such event under clause (b) of the preceding sentence shall
be adjusted by multiplying such amount by a fraction the numerator of which is
the number of shares of Common Stock outstanding immediately after such event
and the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

     (B) The Corporation shall declare a dividend or distribution on the Series
A Junior Participating Preferred Stock as provided in Paragraph (A) above
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock); provided that, in the
event no dividend or distribution shall have been declared on the Common Stock
during the period between any Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on the
Series A Junior Participating Preferred Stock shall nevertheless be payable on
such subsequent Quarterly Dividend Payment Date.

     (C) Dividends shall begin to accrue and be cumulative on outstanding shares
of Series A Junior Participating Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issue of such shares of Series A Junior
Participating Preferred Stock, unless the date of issue of such shares is prior
to the record date for the first Quarterly Dividend Payment Date, in which case
dividends on such shares shall begin to accrue from the date of issue of such
shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a
date after the record date for the determination of holders of shares of Series
A Junior Participating Preferred Stock entitled to receive a quarterly dividend
and before such Quarterly Dividend Payment Date, in either of which events such
dividends shall begin to accrue and be cumulative from such Quarterly Dividend
Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends
paid on the shares of Series A Junior Participating Preferred Stock in an amount
less than the total amount of such dividends at the time accrued and payable on
such shares shall be allocated pro rata on a share-by-share basis among all such
shares at the time outstanding. The Board of Directors may fix a record date for
the determination of holders of shares of Series A Junior Participating
Preferred Stock entitled to receive payment of a dividend or distribution
declared thereon, which record date shall be no more than 30 days prior to the
date fixed for the payment thereof.

     Section 3. Voting Rights. The holders of shares of Series A Junior
Participating Preferred Stock shall have the following voting rights:

     (A) Subject to the provision for adjustment hereinafter set forth, each
share of Series A Junior Participating Preferred Stock shall entitle the holder
thereof to 1000 votes on all matters submitted to a vote of the stockholders of
the Corporation. In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the number of votes per share to which holders of shares of Series A Junior
Participating Preferred



                                      -2-


Stock were entitled immediately prior to such event shall be adjusted by
multiplying such number by a fraction the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

     (B) Except as otherwise provided herein or by law, the holders of shares of
Series A Junior Participating Preferred Stock and the holders of shares of
Common Stock shall vote together as one class on all matters submitted to a vote
of stockholders of the Corporation.

     (C) (i) If at any time dividends on any Series A Junior Participating
Preferred Stock shall be in arrears in an amount equal to six (6) quarterly
dividends thereon, the occurrence of such contingency shall mark the beginning
of a period (herein called a "default period") which shall extend until such
time when all accrued and unpaid dividends for all previous quarterly dividend
periods and for the current quarterly dividend period on all shares of Series A
Junior Participating Preferred Stock then outstanding shall have been declared
and paid or set apart for payment. During each default period, all holders of
Preferred Stock (including holders of the Series A Junior Participating
Preferred Stock) with dividends in arrears in an amount equal to six (6)
quarterly dividends thereon, voting as a class, irrespective of series, shall
have the right to elect two (2) Directors.

     (ii) During any default period, such voting right of the holders of Series
A Junior Participating Preferred Stock may be exercised initially at a special
meeting called pursuant to subparagraph (iii) of this Section 3(c) or at any
annual meeting of stockholders, and thereafter at annual meetings of
stockholders, provided that such voting right shall not be exercised unless the
holders of ten percent (10%) in number of shares of Preferred Stock outstanding
shall be present in person or by proxy. The absence of a quorum of the holders
of Common Stock shall not affect the exercise by the holders of Preferred Stock
of such voting right. At any meeting at which the holders of Preferred Stock
shall exercise such voting right initially during an existing default period,
they shall have the right, voting as a class, to elect Directors to fill such
vacancies, if any, in the Board of Directors as may then exist up to two (2)
Directors or, if such right is exercised at an annual meeting, to elect two (2)
Directors. If the number which may be so elected at any special meeting does not
amount to the required number, the holders of the Preferred Stock shall have the
right to make such increase in the number of Directors as shall be necessary to
permit the election by them of the required number. After the holders of the
Preferred Stock shall have exercised their right to elect Directors in any
default period and during the continuance of such period, the number of
Directors shall not be increased or decreased except by vote of the holders of
Preferred Stock as herein provided or pursuant to the rights of any equity
securities ranking senior to or pari passu with the Series A Junior
Participating Preferred Stock.

     (iii) Unless the holders of Preferred Stock shall, during an existing
default period, have previously exercised their right to elect Directors, the
Board of Directors may order, or any stockholder or stockholders owning in the
aggregate not less than ten percent (10%) of the total number of shares of
Preferred Stock outstanding, irrespective of series, may request, the calling of
a special meeting of the holders of Preferred Stock, which meeting shall
thereupon be called by the President, a Vice-President or the Secretary of the
Corporation. Notice of such



                                      -3-


meeting and of any annual meeting at which holders of Preferred Stock are
entitled to vote pursuant to this Paragraph (C)(iii) shall be given to each
holder of record of Preferred Stock by mailing a copy of such notice to him or
her at his or her last address as the same appears on the books of the
Corporation. Such meeting shall be called for a time not earlier than 20 days
and not later than 60 days after such order or request or in default of the
calling of such meeting within 60 days after such order or request, such meeting
may be called on similar notice by any stockholder or stockholders owning in the
aggregate not less than ten percent (l0%) of the total number of shares of
Preferred Stock outstanding. Notwithstanding the provisions of this Paragraph
(C) (iii), no such special meeting shall be called during the period within 60
days immediately preceding the date fixed for the next annual meeting of the
stockholders.

     (iv) In any default period, the holders of Common Stock, and other classes
of stock of the Corporation if applicable, shall continue to be entitled to
elect the whole number of Directors until the holders of Preferred Stock shall
have exercised their right to elect two (2) Directors voting as a class, after
the exercise of which right (x) the Directors so elected by the holders of
Preferred Stock shall continue in office until their successors shall have been
elected by such holders or until the expiration of the default period, and (y)
any vacancy in the Board of Directors may (except as provided in Paragraph
(C)(ii) of this Section 3) be filled by vote of a majority of the remaining
Directors theretofore elected by the holders of the class of stock which elected
the Director whose office shall have become vacant. References in this Paragraph
(C) to Directors elected by the holders of a particular class of stock shall
include Directors elected by such Directors to fill vacancies as provided in
clause (y) of the foregoing sentence.

     (v) Immediately upon the expiration of a default period, (x) the right of
the holders of Preferred Stock as a class to elect Directors shall cease, (y)
the term of any Directors elected by the holders of Preferred Stock as a class
shall terminate, and (z) the number of Directors shall be such number as may be
provided for in the certificate of incorporation or by-laws irrespective of any
increase made pursuant to the provisions of Paragraph (C)(ii) of this Section 3
(such number being subject, however, to change thereafter in any manner provided
by law or in the certificate of incorporation or by-laws). Any vacancies in the
Board of Directors effected by the provisions of clauses (y) and (z) in the
preceding sentence may be filled by a majority of the remaining Directors.

     (D) Except as set forth herein, holders of Series A Junior Participating
Preferred Stock shall have no special voting rights and their consent shall not
be required (except to the extent they are entitled to vote with holders of
Common Stock as set forth herein) for taking any corporate action.

     Section 4. Certain Restrictions.

     (A) Whenever quarterly dividends or other dividends or distributions
payable on the Series A Junior Participating Preferred Stock as provided in
Section 2 are in arrears, thereafter and until all accrued and unpaid dividends
and distributions, whether or not declared, on shares of Series A Junior
Participating Preferred Stock outstanding shall have been paid in full, the
Corporation shall not



                                      -4-


          (i) declare or pay dividends on, make any other distributions on, or
     redeem or purchase or otherwise acquire for consideration any shares of
     stock ranking junior (either as to dividends or upon liquidation,
     dissolution or winding up) to the Series A Junior Participating Preferred
     stock;

          (ii) declare or pay dividends on or make any other distributions on
     any shares of stock ranking on a parity (either as to dividends or upon
     liquidation, dissolution or winding up) with the Series A Junior
     Participating Preferred Stock, except dividends paid ratably on the Series
     A Junior Participating Preferred Stock and all such parity stock on which
     dividends are payable or in arrears in proportion to the total amounts to
     which the holders of all such shares are then entitled;

          (iii) redeem or purchase or otherwise acquire for consideration shares
     of any stock ranking on a parity (either as to dividends or upon
     liquidation, dissolution or winding up) with the series A Junior
     Participating Preferred Stock, provided that the Corporation may at any
     time redeem, purchase or otherwise acquire shares of any such parity stock
     in exchange for shares of any stock of the Corporation ranking junior
     (either as to dividends or upon dissolution, liquidation or winding up) to
     the Series A Junior Participating Preferred Stock; or

          (iv) purchase or otherwise acquire for consideration any shares of
     Series A Junior Participating Preferred Stock, or any shares of stock
     ranking on a parity with the Series A Junior Participating Preferred Stock,
     except in accordance with a purchase offer made in writing or by
     publication (as determined by the Board of Directors) to all holders of
     such shares upon such terms as the Board of Directors, after consideration
     of the respective annual dividend rates and other relative rights and
     preferences of the respective series and classes, shall determine in good
     faith will result in fair and equitable treatment among the respective
     series or classes.

     (B) The Corporation shall not permit any subsidiary of the Corporation to
purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under Paragraph (A) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

     Section 5. Reacquired Shares. Any shares of Series A Junior Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and cancelled promptly after the acquisition
thereof. All such shares shall upon their cancellation become authorized but
unissued shares of Preferred Stock and may be reissued as part of a new series
of Preferred Stock to be created by resolution or resolutions of the Board of
Directors, subject to the conditions and restrictions on issuance set forth
herein.

     Section 6. Liquidation, Dissolution or Winding Up. (A) Upon any liquidation
(voluntary or otherwise), dissolution or winding up of the Corporation, no
distribution shall be made to the holders of shares of stock ranking junior
(either as to dividends or upon liquidation, dissolution or winding up) to the
Series A Junior Participating Preferred Stock unless, prior thereto, the holders
of Shares of Series A Junior Participating Preferred Stock shall have received
an amount equal to 1000 times the Exercise Price, plus an amount equal to
accrued and unpaid

                                      -5-


dividends and distributions thereon, whether or not declared, to the date of
such payment (the "Series A Liquidation Preference"). Following the payment of
the full amount of the Series A Liquidation Preference, no additional
distributions shall be made to the holders of shares of Series A Junior
Participating Preferred Stock unless, prior thereto, the holders of shares of
Common Stock shall have received an amount per share (the "Common Adjustment")
equal to the quotient obtained by dividing (i) the Series A Liquidation
Preference by (ii) 1000 (as appropriately adjusted as set forth in subparagraph
(C) below to reflect such events as stock splits, stock dividends and
recapitalizations with respect to the Common stock) (such number in clause (ii),
the "Adjustment Number"). Following the payment of the full amount of the Series
A Liquidation Preference and the Common Adjustment in respect of all outstanding
shares of Series A Junior Participating Preferred Stock and Common Stock,
respectively, holders of Series A Junior Participating Preferred stock and
holders of shares of Common Stock shall receive their ratable and proportionate
share of the remaining assets to be distributed in the ratio of the Adjustment
Number to 1 with respect to such Preferred Stock and Common Stock, on a per
share basis, respectively.

     (B) In the event, however, that there are not sufficient assets available
to permit payment in full of the Series A Liquidation Preference and the
liquidation preferences of all other series of preferred stock, if any, which
rank on a parity with the Series A Junior Participating Preferred Stock, then
such remaining assets shall be distributed ratably to the holders of such parity
shares in proportion to their respective liquidation preferences. In the event,
however, that there are not sufficient assets available to permit payment in
full of the Common Adjustment, then such remaining assets shall be distributed
ratably to the holders of Common Stock.

     (C) In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the Adjustment Number in effect immediately prior to such event shall be
adjusted by multiplying such Adjustment Number by a fraction the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

     Section 7. Consolidation, Merger, etc. In case the Corporation shall enter
into any consolidation, merger, combination or other transaction in which the
shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case the shares of
Series A Junior Participating Preferred Stock shall at the same time be
similarly exchanged or changed in an amount per share (subject to the provision
for adjustment hereinafter set forth) equal to 1000 times the aggregate amount
of stock, securities, cash and/or any other property (payable in kind), as the
case may be, into which or for which each share of Common Stock is changed or
exchanged. In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the amount set forth in the preceding sentence with respect to the exchange or
change of shares of Series A Junior Participating Preferred Stock shall be
adjusted by multiplying such amount by a fraction the nu-



                                      -6-


merator of which is the number of shares of Common Stock outstanding immediately
after such event and the denominator of which is the number of shares of Common
Stock that were outstanding immediately prior to such event.

     Section 8. No Redemption. The shares of Series A Junior Participating
Preferred Stock shall not be redeemable.

     Section 9. Amendment. The Amended and Restated Certificate of Incorporation
of the Corporation shall not be further amended in any manner which would
materially alter or change the powers, preferences or special rights of the
Series A Junior Participating Preferred Stock so as to affect them adversely
without the affirmative vote of the holders of a majority or more of the
outstanding shares of Series A Junior Participating Preferred Stock, voting
separately as a class.

     Section 10. Fractional Shares. Series A Junior Participating Preferred
Stock may be issued in fractions of a share which shall entitle the holder, in
proportion to such holders fractional shares, to exercise voting rights, receive
dividends, participate in distributions and to have the benefit of all other
rights of holders of Series A Junior Participating Preferred Stock.

                                                                       EXHIBIT B

                                    RESTATED

                         CERTIFICATE OF INCORPORATION OF

                  TRANSPORTATION TECHNOLOGIES INDUSTRIES, INC.


     FIRST: The name of the Corporation is TRANSPORTATION TECHNOLOGIES
INDUSTRIES, INC. (the "Corporation").

     SECOND: The address of the registered office of the Corporation in the
State of Delaware is 1013 Centre Road, in the City of Wilmington, County of New

have authority to issue is 20,000,000 shares of common stock, par value $0.01
per share (the "Common Stock"), and 400,000 shares of preferred stock, par value
$0.01 per share (the "Preferred Stock"). The Board of Directors of the
Corporation (the "Board of Directors") has authorized the issuance of 173,000
shares of the 14 1/2% Senior Redeemable Preferred Stock, Series A, with such
powers, preferences, rights, qualifications, limitations and restrictions as are
set forth in Exhibit 1 to this Exhibit B.

     (b) The powers, preferences and rights, and the qualifications, limitations

     (1) Subject to clause (2) of this paragraph (b) of this Article FOURTH, the
powers, preferences and rights of the shares of Common Stock, and the
qualifications, limitations and restriction thereof, shall be in all respects
identical.

     (2) The holders of any outstanding shares of Common Stock shall be entitled
to one vote for each share of Common Stock held of record by such holder and
shall be entitled to vote with respect to all matters as to which a stockholder
of a Delaware corporation would be entitled to vote. Notwithstanding the
foregoing, unless permitted under applicable law (as determined by the affected
holder of Common Stock), if shares of Common Stock owned by any person subject
to the provisions of the Bank Holding Company Act of 1956, as amended (the "BHC
Act") (such person is referred to herein as a "Regulated Entity") represent more
than 5% of the total issued and outstanding shares of Common Stock (including
shares of Common Stock held by affiliates (as defined in the BHC Act) of the
Regulated Entity), those shares that represent the excess over the 5% limit
shall be non-voting Common Stock so long as such shares continue to be held by a
Regulated Entity or its affiliates (as defined in the BHC Act), such shares of
non-voting Common Stock shall not be included in determining whether the
requisite percentage



                                      B-1


of shares has consented to, approved, adopted or taken any action and shall in
all other respects be equivalent to all other outstanding shares of Common
Stock; provided that such shares shall not be non-voting on matters that
significantly and adversely affect the rights or preferences of the Common Stock
as determined by such Regulated Entity. Any Common Stock that is non-voting
pursuant to this paragraph while held by a Regulated Entity shall become voting
upon transfer to any entity that is not a Regulated Entity.

     (3) Subject to the rights of the holders of Preferred Stock, holders of
shares of Common Stock shall be entitled to receive dividends and other
distributions in cash, stock or property of the Corporation when, as and if
declared thereon by the Board of Directors from time to time out of assets or
funds of the Corporation legally available therefore.

     (4) In the event of any dissolution, liquidation or winding up of the
Corporation, whether voluntary or involuntary, the holders of shares of Common
Stock shall be entitled to receive the assets and funds of the Corporation
available for distribution after payments to creditors and to the holders of any
Preferred Stock that may at the time be outstanding, in proportion to the number
of shares held by them, respectively.

     (5) Except as otherwise agreed to by the Corporation, no holder of shares
of Common Stock shall be entitled to preemptive or subscription rights.

     FIFTH: (a) The following provisions are inserted for the management of the
business and the conduct of the affairs of the Corporation, and for further
definition, limitation and regulation of the powers of the Corporation and of
its directors and stockholders.

     (1) Subject to the other provisions in this Article FIFTH, the business and
affairs off the Corporation shall be managed by or under the direction of the
Board of Directors. The number of directors of the Corporation shall be not less
than 3 nor more than 10, the exact number to be fixed from time to time by the
Board of Directors.

     (2) Except as otherwise required by law or the provisions hereof, at all
meetings of the Board of Directors, a majority of the entire Board of Directors
shall constitute a quorum for the transaction of business and the act of a
majority of the directors present at any meeting at which there is a quorum
shall be the act of the Board of Directors. If a quorum shall not be present at
any meeting of the Board of Directors, the directors present thereat may adjourn
the meeting from time to time, without notice other than announcement at the
meeting of the time and place of the adjourned meeting, until a quorum shall be
present. Unless otherwise provided herein or in the by-laws of the Corporation,
any action required or permitted to be taken at any meeting of the Board of
Directors or of any committee thereof may be taken without a meeting, if all the
members of the Board of Directors or committee, as the case may be, consent
thereto in writing, and the writing or writings are filed with the minutes of
proceedings of the Board of Directors.

     (3) Except as otherwise provided by law or by the by-laws of the
Corporation, the holders of a majority of the capital stock of the Corporation
issued and outstanding and entitled to vote thereat, present in person or
represented by proxy, shall constitute a quorum at all meetings of the
stockholders of the Corporation for the transaction of business. If, how-



                                      B-2


ever, such quorum shall not be present or represented at any meeting of the
stockholders of the Corporation, the stockholders of the Corporation entitled to
vote thereat, present in person or represented by proxy, shall have power to
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present or represented. At such adjourned
meeting at which a quorum shall be present or represented, any business may be
transacted which might have been transacted at the meeting as originally
noticed. If the adjournment is for more than thirty days, or if after the
adjournment a new record date is fixed for the adjourned meeting, a notice of
the adjourned meeting shall be given to each stockholder of the Corporation
entitled to vote at the meeting. Unless otherwise required by law, the by-laws
of the Corporation or by the provisions of Stockholders' Agreement, dated as of
March 9, 2000 (the "Stockholders Agreement"), by and among Caravalle Investment
Fund, L.L.C., CIBC WMC Inc. Albion Alliance Mezzanine Fund, L.P., Albion
Alliance Mezzanine Fund II, L.P., Transportation Technologies Industries, Inc.,
and the persons listed on Exhibit A attached thereto, who are or become

meeting of stockholders of the Corporation shall be decided by the vote of the
holders of a majority of the stock represented and entitled to vote thereat.
Each stockholder of the Corporation represented at a meeting of stockholders of
the Corporation shall be entitled to cast one vote for each share of the capital
stock entitled to vote thereat held by such stockholder. Any action required or
permitted to be taken at any annual or special meeting of stockholders of the
Corporation, may be taken without a meeting, without prior notice and without a
vote, if a consent in writing, setting forth the action so taken, shall be
signed by the holders of outstanding stock having not less than the minimum
number of votes that would be necessary to authorize or take such action at a
meeting at which all shares entitled to vote thereon were present and voted.
Prompt notice of the taking of the corporate action without a meeting by less
than unanimous written consent shall be given to those shareholders of the
Corporation who have not consented in writing.

     (4) Nothing contained herein or in the Stockholders Agreement, express or
implied, shall relieve any officer or director of the Corporation or any of its
subsidiaries, or any stockholder of the Corporation, of any fiduciary or other
duties or obligations they may have to the stockholders of the Corporation.

     (5) Subject to the provisions of the Stockholders Agreement, the directors
shall have concurrent power with the stockholders of the Corporation to make,
alter, amend, change, add to or repeal the by-laws of the Corporation.

     (6) The number of directors of the Corporation shall be as from time to
time fixed by, or in the manner provided in, the by-laws of the Corporation.
Election of directors need not be by written ballot unless the by-laws of the
Corporation so provide.

     (7) No director shall be personally liable to the Corporation or any of its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to the
Corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii)
pursuant to Section 174 of the GCL or (iv) for any transaction from which the
director derived an improper personal benefit. Any repeal or modification of
this Article FIFTH by the stockholders of the Corporation shall not adversely
affect any right or protection



                                      B-3


of a director of the Corporation existing at the time of such repeal or
modification with respect to acts or omissions occurring prior to such repeal or
modification.

     (8) In addition to the powers and authority hereinbefore or by statute
expressly conferred upon them, the directors are hereby empowered to exercise
all such powers and do all such acts and things as may be exercised or done by
the Corporation, subject, nevertheless, to the provisions of the GCL, this
Amended and Restated Certificate of Incorporation, any by-laws adopted by the
stockholders and the Stockholders Agreement; provided, however, that no by-laws
hereafter adopted by the stockholders shall invalidate any prior act of the
directors which would have been valid if such by-laws had not been adopted.

     SIXTH: At such time as the Corporation has consummated a public offering
and sale of Common Stock for cash pursuant to an effective registration
statement under the Securities Act of 1933, as amended, which public offering
accounted for at least 20% of the outstanding Common Stock of the Corporation on
a fully-diluted basis and yielded net proceeds of not less than $75.0 million,
and without any further action by the Corporation, the Board of Directors or the
Corporation's stockholders, the provisions of this Article SIXTH shall become
and thereafter shall remain effective.

     (a) The Board of Directors shall be divided into three classes, designated
Class I, Class II and Class III, with each class consisting, as nearly as may be
possible, of one-third of the total number of directors constituting the entire
Board of Directors. The then Chairman of the Board of the Corporation shall
designate the initial class of each director. The total of the initial Class I
directors shall terminate on the date of the first annual meeting of
stockholders thereafter; the term of the initial Class II directors shall
terminate on the date of the second annual meeting of stockholders thereafter;
and the term of the initial Class III directors shall terminate on the date of
the third annual meeting of stockholders thereafter. At the first annual meeting
of stockholders after the Board of Directors has been divided into classes and
at each annual meeting of stockholders thereafter, successors to the class of
directors whose term expires at that annual meeting shall be elected for a
three-year term. If the number of directors is changed, any increase or decrease
shall be apportioned among the classes so as to maintain the number of directors
in each class as neatly equal as possible, and any additional directors of any
class elected to fill a vacancy resulting from an increase in such class shall
hold office for a term that shall coincide with the remaining term of that
class, but in no case will a decrease in the number of directors shorten the
term of my incumbent director. Any vacancy on the Board of Directors, however
resulting, may be filled only by a majority of the directors then in office,
even if less than a quorum, or by a sole remaining director. Any director
elected to fill a vacancy shall hold office for a term that shall coincide with
the term of the class to which such director shall have been elected. Any or all
of the directors of the Corporation may be removed from office at any time, but
only for cause and only by the affirmative vote of the holders of a majority of
the outstanding shares of stock of the Corporation then entitled to vote
generally in the election of directors.

     (b) Special meetings of stockholders of the Corporation for any purpose or
purposes may be called at any time by a majority of the Board of Directors, the
Chairman of the Board of Directors or the President of the Corporation. Special
meetings of stockholders of the



                                      B-4


Corporation may not be called by any other person or persons. Any action
required or permitted to be taken at any annual or special meeting of
stockholders may be taken only upon the vote of the stockholders at an annual or
special meeting duly noticed and called, as provided in the by-laws of the
Corporation, and may not be taken by a written consent of the stockholders
pursuant to the GCL.

     SEVENTH: Meetings of stockholders of the Corporation may be held within or
without the State of Delaware, as the by-laws of the Corporation may provide.
The books of the Corporation may be kept (subject to any provision contained in
the GCL) outside the State of Delaware at such place or places as may be
designated from time to time by the Board of Directors or in the by-laws of the
Corporation.

     EIGHTH: In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized to adopt, repeal, alter,
amend or rescind the bylaws of the Corporation; provided, however, that Article
IX of the by-laws of the Corporation shall be amended (a) only with the
affirmative vote of the holders of at least 80% of the outstanding shares of
stock of the Corporation than entitled to vote generally in the election of
directors or (b) by the unanimous vote of the Board of Directors then in office.

     NINTH: Except as contemplated by Article TENTH, the affirmative vote of the
holders of at least 80% of the outstanding shares of stock of the Corporation
then entitled to vote generally in the election of directors shall be required
to amend Articles FIFTH, SIXTH, SEVENTH, EIGHTH or NINTH of this Amended and
Restated Certificate of Incorporation, other than technical amendments.

     TENTH: Except as otherwise contemplated by the provisions of this Amended
and Restated Certificate of Incorporation, the Corporation reserves the right to
amend, alter, change or repeal any provision contained in this Amended and
Restated Certificate of Incorporation, in the manner now or hereafter prescribed
by statute, and all rights conferred upon stockholders of the Corporation herein
are granted subject to this reservation.

Corporation, as "Junior Securities"); (ii) on a parity with any class of Capital
Stock of the Corporation or series of Preferred Stock of the Corporation
hereafter created the terms of which expressly provide that such class or series
will rank on a parity with the Senior Preferred Stock as to dividend
distributions and distributions upon liquidation, winding-up and dissolution
(collectively referred to as "Parity Securities"), provided that any such Parity
Securities that were not approved by the Holder in accordance with paragraph
(f)(ii)(A) hereof (to the extent such approval is required) shall be deemed to
be Junior Securities and not Parity Securities; and (iii) junior to each other
class of Capital Stock of the Corporation or series of Preferred Stock of the
Corporation hereafter created the terms of which expressly provide that such
class or series will rank senior to the Senior Preferred Stock as to dividend
distributions and distributions upon liquidation, winding-up and dissolution of
the Corporation (collectively referred to as "Senior Securities"), provided that
any such Senior Securities that were not approved by the Holders in accordance
with paragraph (f)(ii)(B) hereof shall be deemed to be Junior Securities and not
Senior Securities.



                                     B-1-1


     (c) Dividends.

     (i) From the Issue Date, the Holders of the outstanding shares of Senior
Preferred Stock shall be entitled to receive, when, as and if declared by the
Board of Directors, out of funds legally available therefor, dividends on each
share of Senior Preferred Stock at a rate per annum, equal to 14 1/2% of the
liquidation preference per share of Senior Preferred Stock. All dividends shall
be cumulative, whether or not earned or declared, an a daily basis from the
Issue Date and shall be payable quarterly in arrears on each Dividend Payment
Date, commencing on the first Dividend Payment Date after the Issue Date. All
unpaid dividends will compound on a quarterly basis at a rate per annum equal to
the then applicable dividend rate. Dividends accumulating on or prior to March
15, 2005, shall be paid by the issuance of additional shares of Senior Preferred
Stock (including fractional shares) having an aggregate liquidation preference
equal to the amount of such dividends. In the event that on or prior to March
15, 2005, dividends are declared and paid through the issuance of additional
shares of Senior Preferred Stock as provided in the previous sentence, such
dividends shall be deemed paid in full and shall not accumulate. Dividends
accumulating after March 15, 2005, must be paid in cash (when, as and if
declared by the Board of Directors out of funds legally available therefor). If
(A) any dividend payable on any Dividend Payment Date subsequent to March 15,
2005, is not paid in full in cash on such Dividend Payment Date, or (B) at any
time, any of the types of Voting Rights Triggering Events described in clauses
(2), (3), (4) or (5) of paragraph (f)(iv)(A) shall have occurred, the per annum
dividend rate will be increased by 2.0% per annum (y) from such Dividend Payment
Date until such dividend is paid in full in cash (in the case of clause (A)
above) or (z) from the occurrence of any such Voting Rights Triggering Event
until the termination of any such Voting Rights Triggering Event (in case of
clause (B) above), as the case may be. After the date on which such dividend is
paid in cash or such Voting Rights Triggering Event ceases to exist, the
dividend rate will revert to the rate originally borne by the Senior Preferred
Stock. Each dividend shall be payable to the Holders of record as they appear on
the stock books of the Corporation on the Dividend Record Date immediately
preceding the related Dividend Payment Date.

     (ii) All dividends paid with respect to shares of the Senior Preferred
Stock pursuant to paragraph (c)(i) shall be paid pro rata to the Holders
entitled thereto.

     (iii) Dividends accruing after March 15, 2005, on the Senior Preferred
Stock for any past Dividend Period and dividends in connection with any optional
redemption pursuant to paragraph (e)(i) may be declared and paid at any time,
without reference to any Dividend Payment Date, to Holders of record on such
date, not more than forty-five (45) days prior to the payment thereof, as may be
fixed by the Board of Directors.

     (iv) (A) No full dividends shall be declared by the Board of Directors or
paid or set apart for payment by the Corporation on any Parity Securities for
any period unless (1) full cumulative dividends have been or contemporaneously
are declared and paid in full, or declared and, if payable in cash, a sum in
cash set apart sufficient for such payment, on the Senior Preferred Stock for
all Dividend Periods terminating on or prior to the date of payment of such full
dividends on such Parity Securities and (2) such payment is in compliance with
paragraph (k)(ii) hereof. If any dividends are not so paid, all dividends
declared upon shares of the



                                     B-1-2


Senior Preferred Stock and any other Parity Securities shall be declared pro
rata so that the amount of dividends declared per share on the Senior Preferred
Stock and such Parity Securities shall in all cases bear to each other the same
ratio that accrued dividends per share on the Senior Preferred Stock and such
Parity Securities bear to each other.

     (B) So long as any share of the Senior Preferred Stock is outstanding, the
Corporation shall not declare, pay or set apart for payment any dividend on any
of the Junior Securities (other than dividends in Junior Securities to the
holders of Junior Securities), or make any payment on account of, or set apart
for payment money for a sinking or other similar fund for, the purchase,
redemption or other retirement of, any of the Junior Securities or any warrants,
rights, calls or options exercisable for or convertible into any of the Junior
Securities whether in cash, obligations or shares of the Corporation or other
property (other than in exchange for Junior Securities), and shall not permit
any corporation or other entity directly or indirectly controlled by the
Corporation to purchase or redeem any of the Junior Securities or any such
warrants, rights, calls or options (other than in exchange for Junior
Securities) unless (1) full cumulative dividends determined in accordance
herewith on the Senior Preferred Stock have been paid in full for all full
quarterly dividend periods ended prior to the date of such payment in respect of
Junior Securities and (2) such payment is in compliance with paragraph (k)(ii)
hereof.

     (C) So long as any share of the Senior Preferred Stock is outstanding, the
Corporation shall not (except with respect to dividends as permitted by
paragraph (c)(iv)(A)) make any payment on account of, or set apart for payment
money for a sinking or other similar fund for, the purchase, redemption or other
retirement of, any of the Parity Securities or any warrants, rights, calls or
options exercisable for or convertible into any of the Parity Securities whether
in cash, obligations or shares of the Corporation or other property, and shall
not permit any corporation or other entity directly or indirectly controlled by
the Corporation to purchase or redeem any of the Parity Securities or any such
warrants, rights, calls or options unless (1) full cumulative dividends
determined in accordance herewith on the Senior Preferred Stock have been or
contemporaneously are paid in full and (2) such payment is in compliance with
paragraph (k)(ii) hereof.

     (v) Dividends payable on the Senior Preferred Stock for any period less
than a year shall be computed on the basis of a 360-day year of twelve 30-day
months and, for periods not involving a full calendar month, the actual number
of days elapsed (not to exceed 30 days).

     (vi) Additional Dividends shall become due and payable with respect to the
Senior Preferred Stock on the terms and subject to the conditions set forth in
the Registration Rights Agreement.

     (d) Liquidation Preference.

     (i) In the event of any voluntary or involuntary liquidation, dissolution
or winding-up of the affairs of the Corporation, the Holders of shares of Senior
Preferred Stock then outstanding shall be entitled to be paid out of the assets
of the Corporation available for distribution to its stockholders an amount in
cash equal to the liquidation preference for each share outstanding, plus,
without duplication, an amount in cash equal to accumulated and unpaid dividends
thereon to the date fixed for liquidation, dissolution or winding-up (including
an amount



                                     B-1-3


equal to a prorated dividend for the period from the last Dividend Payment Date
to the date fixed for liquidation, dissolution or winding-up) before any
distribution shall be made or any assets distributed in respect of Junior
Securities to the holders of any Junior Securities including, without
limitation, Common Stock of the Corporation. If upon any voluntary or
involuntary liquidation, dissolution or winding-up of the Corporation, the
amounts payable with respect to the Senior Preferred Stock and all other Parity
Securities are not paid in full, the Holders of the Senior Preferred Stock and
the Parity Securities will share equally and ratably in any distribution of
assets of the Corporation first in proportion to the full liquidation preference
to which each is entitled until such preferences are paid in full, and then in
proportion to their respective amounts of accumulated but unpaid dividends.

     (ii) For the purposes of this paragraph (d), neither the sale, conveyance,
exchange or transfer (for cash, shares of stock, securities or other
consideration) of all or substantially all of the property or assets of the
Corporation nor the consolidation or merger of the Corporation with or into one
or more entities shall be deemed to be a liquidation, dissolution or winding-up
of the affairs of the Corporation.

     (e) Redemption.

     (i) Optional Redemption. (A) The Corporation may redeem the Senior
Preferred Stock at its option, in whole at any time or in part from time to
time, on or after the Issue Date, subject to contractual and other restrictions
with respect thereto, from any source of funds legally available therefor, in
the manner provided for in paragraph (e)(iii) hereof, at the redemption prices
in cash (expressed as a percentage of the liquidation preference) set forth
below, plus, without duplication, an amount in cash equal to all accumulated and
unpaid dividends (including Additional Dividends, if any) (including an amount
in cash equal to a prorated dividend for the period from the Dividend Payment
Date immediately prior to the Redemption Date to the Redemption Date) if
redeemed during the 12-month period beginning on each date listed below:

           Issue Date.................................     114.500%

           March 15, 2001.............................     114.500%

           March 15, 2002.............................     114.500%

           March 15, 2003.............................     112.083%

           March 15, 2004.............................     109.667%

           March 15, 2008 and thereafter .............     100.000%;

provided that no redemption pursuant to this paragraph (e)(i)(A) shall be
authorized or made unless prior thereto full accumulated and unpaid dividends
(including Additional Dividends, if any) are declared and paid in full, or
declared and a sum in cash is set apart sufficient for such



                                     B-1-4


payment, on the Senior Preferred Stock for all Dividend Periods terminating on
or prior to the Redemption Date.

     (B) In the event of a redemption pursuant to paragraph (e)(i)(A) hereof of
only a portion of the then outstanding shares of Senior Preferred Stock, the
Corporation shall effect such redemption on a pro rata basis according to the
number of shares held by each Holder of Senior Preferred Stock, except that the
Corporation may redeem such shares held by Holders of fewer than one share (or
shares held by Holders who would hold less than one share as a result of such
redemption), as may be determined by the Corporation.

     (ii) Mandatory Redemption. On March 15, 2010 (the "Mandatory Redemption
Date"), the Corporation shall redeem, to the extent of funds legally available
therefor, all of the shares of Senior Preferred Stock then outstanding at a
redemption price equal to 100% of the liquidation preference per share, plus,
without duplication, an amount in cash equal to all accumulated and unpaid
dividends (including Additional Dividends, if any) per share (including an
amount equal to a prorated dividend for the period from the Dividend Payment
Date immediately prior to the Redemption Date to the Redemption Date) (the
"Mandatory Redemption Price").

     (iii) Procedures for Redemption. At least 15 days and not more than 90 days
prior to the date fixed for any redemption of the Senior Preferred Stock,
written notice (the "Redemption Notice") shall be given by first-class mail,
postage prepaid, to each Holder of record on the record date fixed for such
redemption of the Senior Preferred Stock at such Holder's address as it appears
in the register maintained by the transfer agent for the Senior Preferred Stock,
provided that no failure to give such notice nor any deficiency therein shall
affect the validity of the procedure for the redemption of any shares of Senior
Preferred Stock to be redeemed except as to the Holder or Holders to whom the
Corporation has failed to give said notice or except as to the Holder or Holders
whose notice was defective. The Redemption Notice shall state:

          (1) that the redemption is pursuant to paragraph (e)(i)(A) hereof;

          (2) the redemption price;

          (3) whether all or less than all the outstanding shares of Senior
     Preferred Stock are to be redeemed and the total number of shares of Senior
     Preferred Stock being redeemed;

          (4) the Redemption Date;

          (5) that the Holder is to surrender to the Corporation, in the manner,
     at the place or places and at the price designated, his certificate or
     certificates representing the shares of Senior Preferred Stock to be
     redeemed; and

          (6) that dividends on the shares of Senior Preferred Stock to be
     redeemed shall cease to accumulate on such Redemption Date unless the
     Corporation defaults in the payment of the redemption price.



                                     B-1-5


     (C) Each Holder of Senior Preferred Stock shall surrender the certificate
or certificates representing such shares of Senior Preferred Stock to the
Corporation, duly endorsed (or otherwise in proper form for transfer, as
determined by the Corporation), in the manner and at the place designated in the
Redemption Notice, and on the Redemption Date the full redemption price for such
shares shall be payable in cash to the Person whose name appears on such
certificate or certificates as the owner thereof, and each surrendered
certificate shall be canceled and retired. In the event that less than all of
the shares represented by any such certificate are redeemed, a new certificate
shall be issued representing the unredeemed shares.

     (D) On and after the Redemption Date, unless the Corporation defaults in
the payment in full of the applicable redemption price, dividends on Senior
Preferred Stock called for redemption shall cease to accumulate on the
Redemption Date, and all rights of the Holders of redeemed shares shall
terminate with respect thereto on the Redemption Date, other than the right to
receive the redemption price; provided, however, that if a notice of redemption
shall have been given as provided in paragraph (iii)(A) above and the funds
necessary for redemption (including an amount in cash in respect of all
dividends that will accumulate to the Redemption Date) shall have been
irrevocably deposited in trust for the equal and ratable benefit for the Holders
of the shares of Senior Preferred Stock to be redeemed, then, at the close of
business on the Business Day on which such funds are segregated and set aside,
the Holders of the shares to be redeemed shall cease to be stockholders of the
Corporation and shall be entitled only to receive the redemption price.

     (f) Voting Rights.

     (i) The Holders of Senior Preferred Stock, except as otherwise required
under Delaware law or as set forth in paragraphs (ii), (iii) and (iv) below,
shall not be entitled or permitted to vote on any matter required or permitted
to be voted upon by the stockholders of the Corporation.

     (ii) (A) So long as any shares of Senior Preferred Stock are outstanding,
the Corporation shall not authorize or issue any class of Parity Securities
without the affirmative vote or consent of Holders of at least a majority of the
then outstanding shares of Senior Preferred Stock, voting or consenting, as the
case may be, as one class, given in person or by proxy, either in writing or by
resolution adopted at an annual or special meeting; provided, however, that no
such vote or consent shall be necessary in connection with the issuance of
additional shares of Senior Preferred Stock pursuant to the provisions of
paragraph (c) of this Certificate of Designation.

     (B) So long as any shares of Senior Preferred Stock are outstanding, the
Corporation shall not authorize or issue any class of Senior Securities without

outstanding shares of Senior Preferred Stock, voting or consenting, as the case
may be, as one class, given in person or by proxy, either in writing or by
resolution adopted at an annual or special meeting.

     (C) So long as any shares of Senior Preferred Stock are outstanding, the
Corporation shall not amend its Certificate of Incorporation or this Resolution
and Certificate of Designation so as to affect adversely the rights,
preferences, privileges or voting rights of



                                     B-1-6


Holders of shares of Senior Preferred Stock without the affirmative vote or
consent of Holders of at least a majority of the issued and outstanding shares
of Senior Preferred Stock, voting or consenting, as the case may be, as one
class, given in person or by proxy, either in writing or by resolution adopted
at an annual or special meeting; provided, however, that, without the
affirmative vote or consent of each Holder of shares of Senior Preferred Stock
affected, an amendment may not: (I) reduce the percentage of outstanding shares
of Senior Preferred Stock whose Holders must consent to an amendment; (II)
reduce the rate of or change the time for payment of dividends (including
Additional Dividends) on any share of Senior Preferred Stock; (III) reduce the
liquidation preference of or change or have the effect of changing the fixed
redemption date of any share of Senior Preferred Stock, or change the date on
which any share of Senior Preferred Stock may be subject to redemption or
repurchase, or reduce the redemption or repurchase price therefor; (IV) make any
share of Senior Preferred Stock payable in money other than that stated herein;
or (V) affect the ranking of the Senior Preferred Stock in a manner adverse to
the Holders.

     (iii) Without the affirmative vote or consent of Holders of a majority of
the issued and outstanding shares of Senior Preferred Stock, voting or
consenting, as the case may be, as a separate class, given in person or by
proxy, either in writing or by resolution adopted at an annual or special
meeting, the Corporation shall not, in a single transaction or series of related
transactions, consolidate with or merge with or into, or sell, assign, transfer,
lease, convey or otherwise dispose of all or substantially all of its assets to,
another Person unless: (I) at or prior to the consummation of such transaction
all of the then outstanding shares of the Senior Preferred Stock are redeemed in
accordance with the provisions of this Certificate of Designation or (II) (A)
either (1) the Corporation is the continuing Person or (2) the Person (if other
than the Corporation) formed by such consolidation or into which the Corporation
is merged or to which the properties and assets of the Corporation are sold,
assigned, transferred, leased, conveyed or otherwise disposed of shall be a
corporation organized and existing under the laws of the United States or any
State thereof or the District of Columbia and shall expressly assume all of the
obligations of the Corporation under this Resolution and Certificate of
Designation and the obligations hereunder and thereunder shall remain in full
force and effect; (B) if the Corporation is not the surviving Person, the Senior
Preferred Stock shall be converted into or exchanged for and shall become shares
of such successor, transferee or resulting Person, having in respect of such
successor, transferee or resulting Person the same powers, preferences and
relative, participating, optional or other special rights and the
qualifications, limitations or restrictions thereon, and ranking in relation to
all other Capital Stock then outstanding, that the Senior Preferred Stock had
immediately prior to such transaction; (C) except in the case of the Merger,
immediately after giving effect to such transaction on a pro forma basis the
Corporation or such Person (1) could incur at least $1.00 of additional
Indebtedness (other than Permitted Indebtedness) in compliance with paragraph
(k)(i) and (2) will have a Consolidated Net Worth equal to or greater than the
Consolidated Net Worth of the Corporation immediately prior to such transaction;
and (D) except in the case of the Merger, immediately after giving effect to
such transaction (including any Indebtedness incurred or anticipated to be
incurred in connection with the transaction), no Voting Rights Triggering Event
shall have occurred or be continuing.

     For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise, in a single transaction or series of related transactions) of all or
substantially all of the



                                     B-1-7


properties or assets of one or more Restricted Subsidiaries of the Corporation,
the Capital Stock of which constitutes all or substantially all of the
properties and assets of the Corporation shall be deemed to be the transfer of
all or substantially all of the properties and assets of the Corporation.

     (iv) (A) If (1) after March 15, 2005, cash dividends on the Senior
Preferred Stock are in arrears and unpaid for three or more quarterly Dividend
Periods (whether or not consecutive) (a "Dividend Default"); (2) the Corporation
fails to redeem all of the then outstanding shares of Senior Preferred Stock on
or before the Mandatory Redemption Date or otherwise fails to discharge any
redemption obligation with respect to the Senior Preferred Stock; (3) the
Corporation fails to make a Change of Control Offer following a Change of
Control if such Change of Control Offer is required by paragraph (g) hereof or
fails to purchase shares of Senior Preferred Stock from Holders who elect to
have such shares purchased pursuant to the Change of Control Offer; (4) the
Corporation breaches or violates one of the provisions set forth in paragraph
(c)(iv), (d), (f)(ii), (f)(iii) or (k) hereof and the breach or violation
continues for a period of 60 says or more after the Corporation receives written
notice thereof specifying the default from the Holders of at least 25% of the
shares of Senior Preferred Stock then outstanding; or (5) the Corporation fails
to pay when due (giving effect to any applicable grace periods and any waiver or
extension thereof) principal, interest or premium with respect to any
Indebtedness of the Corporation or any Restricted Subsidiary thereof, or any
such Indebtedness is accelerated, if the aggregate amount of such Indebtedness,
together with the amount of any other such Indebtedness in default for failure
to pay principal, interest or premium or which has been accelerated, aggregates
$10.0 million or more at any time; then in the case of any of clauses (1)
through (5) (each of such clauses (1) through (5) a "Voting Rights Triggering
Event"), the number of directors constituting the Board of Directors shall be
adjusted by the number, if any, necessary to permit the Holders of the Senior
Preferred Stock, voting or consenting separately and as one class, to elect the
lesser of two directors or that number of directors constituting at least 20% of
the Board of Directors; provided, that, in the event more than one of the above
defaults occurs, at the same or at different times, the maximum number of
directors that such Holders shall be entitled to elect is the lesser of two
directors and that number of directors constituting 20% of the Board of
Directors. Holders of a majority of the issued and outstanding shares of Senior
Preferred Stock, voting separately and as one class, shall have the exclusive
right to elect the lesser of two directors or 20% of the members of the Board of
Directors at a meeting therefor called upon occurrence of such Voting Rights
Triggering Event, and at every subsequent meeting at which the terms of office
of the directors so elected by the Holders of Senior Preferred stock expire
(other than as described in paragraph (f)(iv)(B) below).

     (B) The right of the Holders of the Senior Preferred Stock voting or
consenting together as a separate class to elect members of the Board of
Directors as set forth in paragraph (f)(iv)(A) above shall continue until such
time as (x) in the event such right arises due to a Dividend Default, all
accumulated dividends that are in arrears on the Senior Preferred Stock are paid
in full in cash, and (y) in all other cases, the failure, breach or default
giving rise to such Voting Rights Triggering Event is remedied, cured or waived
by the Holders of at least a majority of the shares of Senior Preferred Stock
then outstanding and entitled to vote thereon, at which time (1) the special
right of the Holders of Senior Preferred Stock so to vote or consent as a class
for the election of directors and (2) the term of office of the directors
elected by the Holders of



                                     B-1-8


Senior Preferred Stock shall each terminate and the directors elected by the
holders of Common Stock or Capital Stock (other than the Senior Preferred Stock)
shall constitute the entire Board of Directors. At any time after voting power
to elect directors shall have become vested and be continuing in the Holders of
Senior Preferred Stock pursuant to this paragraph (f)(iv), or if vacancies shall
exist in the offices of directors elected by the Holders of Senior Preferred
Stock, (1) the Holders of a majority of the issued and outstanding shares of
Senior Preferred Stock may consent to the election of directors which such
Holders are entitled to elect or (2) a proper officer of the Corporation may,
and upon the written request of the Holders of record of at least 25% of the
shares of Senior Preferred Stock then outstanding addressed to the secretary of
the Corporation shall, call a special meeting of the Holders of Senior Preferred
Stock, for the purpose of electing the directors which such Holders are entitled
to elect. If such meeting shall not be called by a proper officer of the
Corporation within 20 days after personal service of said written request upon
the secretary of the Corporation, or within 20 days after mailing the same
within the United States by certified mail, addressed to the secretary of the
Corporation at its principal executive offices, then the Holders of record of at
least 25% of the outstanding shares of Senior Preferred Stock may designate in
writing one Holder to call such meeting at the expense of the Corporation, and
such meeting may be called by the Person so designated upon the notice required
for the annual meetings of stockholders of the Corporation and shall be held at
the place for holding the annual meetings of stockholders. Any Holder of Senior
Preferred Stock so designated shall have, and the Corporation shall provide,
access to the lists of stockholders to be called pursuant to the provisions
hereof.

     (C) At any meeting held for the purpose of electing directors at which the
Holders of Senior Preferred Stock shall have the right, voting together as a
separate class, to elect directors as aforesaid, the presence in person or by
proxy of the Holders of at least a majority of the outstanding shares of Senior
Preferred Stock entitled to vote thereat shall be required to constitute a
quorum of the Senior Preferred Stock.

     (D) Any vacancy occurring in the office of a director elected by the
Holders of the Senior Preferred Stock may be filled by the remaining director
elected by the Holders of the Senior Preferred Stock unless and until such
vacancy shall be filled by the Holders of the Senior Preferred Stock.

     (v) In any case in which the Holders of the Senior Preferred Stock shall be
entitled to vote pursuant to this paragraph (f) or pursuant to Delaware law,
each holder of Senior Preferred Stock entitled to vote with respect to such
matter shall be entitled to one vote for each share of Senior Preferred Stock
held.

     (g) Change of Control.

     (i) Upon the occurrence of a Change of Control (the date of such occurrence
being the "Change of Control Date"), the Corporation shall make an offer to
purchase (the "Change of Control Offer") the outstanding shares of Senior
Preferred Stock at a purchase price equal to 101% of the liquidation preference
thereof, plus, without duplication, an amount in cash equal to all accumulated
and unpaid dividends (including Additional Dividends, if any) thereon (including
an amount in cash equal to a prorated dividend for the period from the
immediately



                                     B-1-9


preceding Dividend Payment Date to the Change of Control Payment Date) (the
"Change of Control Purchase Price").

     (ii) Within 30 days of the occurrence of a Change of Control, the
Corporation also shall send by first-class mail, postage prepaid, to each Holder
of Senior Preferred Stock, at the address appearing in the register maintained
by the transfer agent for the Senior Preferred Stock, a notice stating:

          (1) that the Change of Control Offer is being made pursuant to this
     paragraph (g) and that all of the Senior Preferred Stock tendered will be
     accepted for payment, and otherwise subject to the terms and conditions set
     forth herein;

          (2) the Change of Control Purchase Price and the purchase date (which
     shall be a Business Day no earlier than 30 days nor later than 45 days from
     the date such notice is mailed (the "Change of Control Payment Date"));

          (3) that any of the Senior Preferred Stock not tendered will continue
     to accumulate dividends;

          (4) that, unless the Corporation defaults in the payment of the Change
     of Control Purchase Price, any of the Senior Preferred Stock accepted for
     payment pursuant do the Change of Control Offer shall cease to accumulate
     dividends after the Change of Control Payment Date;

          (5) that Holders accepting the offer to have their Senior Preferred
     Stock purchased pursuant to a Change of Control Offer will be required to
     surrender their certificates representing the Senior Preferred Stock to the
     Corporation, properly endorsed for transfer together with such customary
     documents as the Corporation and the transfer agent may reasonably require,
     in the manner and at the address specified in the notice prior to the close
     of business on the Business Day preceding the Change of Control Payment
     Date;

          (6) that Holders will be entitled to withdraw their acceptance if the
     Corporation receives, not later than the close of business on the third
     Business Day preceding the Change of Control Payment Date, a telegram,
     telex, facsimile transmission or letter setting forth the name of the
     Holder, the number of shares of Senior Preferred Stock delivered for
     purchase, and a statement that such Holder is withdrawing its election to
     have such Senior Preferred Stock purchased;

          (7) that Holders whose shares of Senior Preferred Stock are being
     purchased only in part will be issued new certificates representing the
     number of shares of Senior Preferred Stock equal to the unpurchased portion
     of the certificates surrendered; and

          (8) any other reasonable procedures that a Holder must follow to
     accept a Change of Control Offer or effect withdrawal of such acceptance.

     (iii) The Corporation will comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of shares of Senior Preferred Stock pursuant to a Change of Control
Offer. To the extent that the provisions of any securities laws or regulations
conflict with the provisions of this paragraph (g), the Corporation will comply
with the applicable securities laws and regulations and will not be deemed to
have breached its obligations under this paragraph (g) by virtue thereof.

     (iv) On the Change of Control Payment Date, the Corporation shall (A)
accept for payment the shares of Senior Preferred Stock validly tendered
pursuant to the Change of Control Offer, (B) promptly mail to the Holders of
shares so accepted the Change of Control Purchase Price therefor in cash and (C)
cancel and retire each surrendered certificate and execute a new certificate
representing that number of shares of Senior Preferred Stock equal to any
unpurchased shares represented by a certificate surrendered. Unless the
Corporation defaults in the payment for the shares of Senior Preferred Stock
tendered pursuant to the Change of Control Offer, dividends shall cease to
accumulate with respect to the shares of Senior Preferred Stock tendered and all
rights of Holders of such tendered shares shall terminate, except for the right
to receive payment therefor, on the Change of Control Payment Date.

     (v) If the repurchase of the Senior Preferred Stock pursuant to this
paragraph (g) would violate or constitute a default or be otherwise prohibited
under any Indebtedness of the Corporation then outstanding, then,
notwithstanding anything to the contrary contained above, prior to complying
with the foregoing provisions, but in any event within 30 days following the
Change of Control Date, the Corporation shall, to the extent required to permit
the repurchase of the Senior Preferred Stock required by this paragraph (g),
either (A) repay in full all obligations and terminate all commitments under or
in respect of all outstanding Indebtedness the terms of which prohibit the
purchase by the Corporation of the Senior Preferred Stock upon a Change of
Control in compliance with the terms of this paragraph (g) or offer to repay in
full all obligations and terminate all commitments under or in respect of all
such Indebtedness and repay the Indebtedness owed to each such lender who has
accepted such offer or (B) obtain the requisite consents, if any, under such
Indebtedness containing such prohibition to permit the repurchase of the Senior
Preferred Stock required by this paragraph (g). The Corporation must first
comply with the covenant described in the preceding sentence before it shall be
required to purchase shares of Senior Preferred Stock in the event of a Change
of Control; provided that the Corporation's failure to consummate a Change of
Control Offer in accordance with the provisions of this covenant due to the
covenant described in the immediately preceding sentence shall constitute a
Voting Rights Triggering Event described in clause (3) of the definition of
"Voting Rights Triggering Event."

     (h) Conversion or Exchange. The Holders of shares of Senior Preferred Stock
shall not have any rights hereunder to convert such shares into or exchange such
shares for shares of any other class or classes or of any other series of any
class or classes of Capital Stock of the Corporation other than as provided in
this Resolution and Certificate of Designation and the Registration Rights
Agreement.



                                     B-1-11


     (i) Reissuance of Senior Preferred Stock. Shares of Senior Preferred Stock
that have been issued and reacquired in any manner, including shares purchased
or redeemed or exchanged, shall (upon compliance with any applicable provisions
of the laws of Delaware) have the status of authorized and unissued shares of
Preferred Stock undesignated as to series and may be redesignated and reissued
as part of any series of Preferred Stock; provided that shares of Senior
Preferred Stock reacquired pursuant to the exchange offer contemplated by the
Registration Rights Agreement shall be reissued as Senior Preferred Stock with
the series designation referred to in paragraph (a) hereof; and provided,
further, that any issuance of such shares of Senior Preferred Stock must be in
compliance with the terms hereof.

     (j) Business Day. If any payment, redemption or exchange shall be required
by the terms hereof to be made on a day that is not a Business Day, such
payment, redemption or exchange shall be made on the immediately succeeding
Business Day.

     (k) Certain Covenants.

     (i) Limitation on Additional Indebtedness. The Corporation will not, and
will not permit any of its Restricted Subsidiaries to, directly or indirectly,
incur any Indebtedness (including Acquired Indebtedness); provided that, from
and after the Effective Time, the Corporation or any of its Restricted
Subsidiaries may incur Indebtedness (including Acquired Indebtedness) if, after
giving effect to the incurrence of such Indebtedness and the receipt and
application of the proceeds thereof, the Corporation's Consolidated Fixed Charge
Coverage Ratio is at least 2.0 to 1 if the Indebtedness is incurred prior to
September 9, 2001 and 2.25 to 1 if the Indebtedness is incurred thereafter.

     Notwithstanding the foregoing, the Corporation and its Restricted
Subsidiaries may incur Permitted Indebtedness.

     Notwithstanding any other provision of this paragraph (k)(i), in the event
that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Indebtedness or is otherwise entitled to be incurred
pursuant to this paragraph (k)(i), the Corporation may, in its sole discretion,
classify (or reclassify) such item of Indebtedness in any manner that complies
with this paragraph and such items of Indebtedness will be treated as having
been incurred pursuant to only one of the categories of Permitted Indebtedness
or pursuant to the first paragraph hereof. Accrual of interest or accretion of
accreted value will not be deemed to be an incurrence of Indebtedness for
purposes of this paragraph.

     (ii) Limitation on Restricted Payments.

     (A) The Corporation will not make, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, make any Restricted Payment;
provided that from and after the Effective Time the Corporation and its
Restricted Subsidiaries may make Restricted Payments if:

          (1) no Voting Rights Triggering Event shall have occurred and be
     continuing at the time of or immediately after giving effect to such
     Restricted Payment;



                                     B-1-12


          (2) immediately after giving pro forma effect to such Restricted
     Payment, the Corporation could incur $1.00 of additional Indebtedness
     (other than Permitted Indebtedness) in compliance with paragraph (k)(i);
     and

          (3) immediately after giving effect to such Restricted Payment, the
     aggregate of all Restricted Payments declared or made after the Issue Date
     does not exceed the sum of, without duplication:

               (a) 50% of the Corporation's Cumulative Consolidated Net Income
          (or minus 100% of any cumulative deficit in Consolidated Net Income
          during such period);

               (b) 100% of the aggregate Net Proceeds received by the
          Corporation from the issue or sale after the Issue Date of Capital
          Stock (other than Disqualified Capital Stock or Capital Stock of the
          Corporation issued to any Subsidiary of the Corporation or to an
          employee stock ownership plan or other trust established by the
          Corporation or any of its Subsidiaries for the benefit of their
          employees to the extent the purchase by such plan or trust is financed
          by Indebtedness of such plan or trust and for which the Corporation is
          liable as guarantor or otherwise) of the Corporation or any
          Indebtedness or other securities of the Corporation convertible into
          or exercisable or exchangeable for Capital Stock (other than
          Disqualified Capital Stock) of the Corporation which have been so
          converted, exercised or exchanged, as the case may be;

               (c) without duplication of any amounts included in clause (3) (b)
          above, 100% of the aggregate Net Proceeds received by the Corporation
          from any equity contribution from a holder of the Corporation's
          Capital Stock; and

               (d) without duplication, the sum of:

                    (i) the aggregate amount returned in cash on or with respect
               to an investment; (other than a Permitted Investment) made
               subsequent to the Issue Date whether through interest payments,
               principal payments, dividends and other distributions;

                    (ii) the net proceeds received by the Corporation or any of
               its Restricted Subsidiaries from the disposition (other than to
               the Corporation or a Subsidiary of the Corporation), retirement
               or redemption of all or any portion of an Investment described in
               clause (3) (d)(i); and

                    (iii) upon redesignation of an Unrestricted Subsidiary as a
               Restricted Subsidiary, the fair market value of the net assets of
               such Subsidiary;

          provided, however, that, with respect to an Investment in any Person,
          the sum of clauses (i), (ii) and (iii) above with respect to the
          Investment in such Person may



                                     B-1-13


          not exceed the aggregate amount of all Investments made in such Person
          subsequent to the Issue Date.

     For purposes of determining under clause (3) above, the amount expended for
Restricted Payments, cash distributed shall be valued at the face amount thereof
and property other than cash shall be valued at its fair market value.

     (B) The provisions of this covenant shall not prohibit

               (1) from and after the Effective Time, the payment of any
          distribution within 60 days after the date of declaration thereof, if
          at such date of declaration such payment would comply with the
          provisions of this Resolution and Certificate of Designation;

               (2) from and after the Effective Time, the repurchase,
          redemption, defeasance or other acquisition or retirement of any
          shares of Capital Stock of the Corporation by conversion into, or by
          or in exchange for, shares of Capital Stock of the Corporation (other
          than Disqualified Capital Stock), or out of the Net Proceeds of the
          substantially concurrent sale (other than to a Subsidiary of the
          Corporation or to an employee stock ownership plan or other trust
          established by the Corporation or any of its Subsidiaries for the
          benefit of their employees to the extent the purchase by such plan or
          trust is financed by Indebtedness of such plan or trust and for which
          the Corporation is liable as guarantor or otherwise) of other shares
          of Capital Stock of the Corporation (other than Disqualified Capital
          Stock);

               (3) Restricted Payments made pursuant to the terms of the Tender
          Offers and the Agreement and Plan of Merger, Including transaction
          fees and expenses;

               (4) the repurchase of shares of, or options to purchase shares
          of, Common Stock of the Corporation or any of its Subsidiaries from
          employees, former employees, directors or former directors of the
          Corporation or any of its Subsidiaries (or permitted transferees of
          such employees, former employees, directors or former directors),
          pursuant to the terms of the agreements (including employment
          agreements and stockholders' agreements) or plans (or amendments
          thereto) approved by the Board of Directors under which such persons
          purchase or sell or are granted the option to purchase or sell, shares
          of such Common Stock; provided, however, that the aggregate amount of
          such repurchases shall not exceed $1.0 million; and

               (5) so long as no Voting Rights Triggering Event shall have
          occurred and be continuing, the payment of management and other
          related fees (including, without limitation, director's fees) not to
          exceed during any fiscal year an amount equal to $1.5 million plus the
          amount of previously accrued but unpaid management fees and related
          fees from prior fiscal years.

     (C) In calculating the aggregate amount of Restricted Payments made
subsequent to the Issue Date for purposes of clause (A)(3), amounts expended
pursuant to clauses (B)(1) and (4) shall be included in such calculation.



                                     B-1-14


     The amount of all Restricted Payments (other than cash) shall be the fair
market value on the date of the Restricted Payment of the asset(s) or securities
proposed to be acquired, transferred or issued to or by the Corporation or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.

          (iii) Limitation on Transactions with Affiliates.

     (A) The Corporation will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, enter into any transaction or series of
related transactions (including, without limitation, the sale, purchase,
exchange or lease of assets, property or services) with or for the benefit of
any Affiliate (each, an "Affiliate Transaction") or extend, renew, waive or
otherwise modify the terms of any Affiliate Transaction entered into prior to
the Issue Date unless

          (1) such Affiliate Transaction is between or among the Corporation and
     one or more of its Wholly Owned Subsidiaries; or

          (2) the terms of such Affiliate Transaction are fair and reasonable to
     the Corporation or such Restricted Subsidiary, as the case may be, and the
     terms of such Affiliate Transaction are at least as favorable as the terms
     which could be obtained by the Corporation or such Restricted Subsidiary,
     as the case may be, in a comparable transaction made on an arm's-length
     basis between unaffiliated parties.

     (B) In any Affiliate Transaction (or any series of related Affiliate
Transactions which are similar or part of a common plan) involving an amount or

of Directors of the Corporation certifying that such Affiliate Transaction
complies with clause (A)(2) above. In any Affiliate Transaction (or any series
of related Affiliate Transactions which are similar or part of a common plan)

favorable written opinion as to the fairness of such transaction or
transactions, as the case may be, from an Independent Financial Advisor.

     in accordance with the past practices of the Corporation or its Restricted
     Subsidiaries, but in any event not to exceed $1.0 million in the aggregate
     outstanding at any one time;

          (5) any agreement as in effect as of the Issue Date or any amendment
     thereto or any transaction contemplated thereby (including pursuant to any
     amendment thereto) in any replacement agreement thereto so long as any such

     Disqualified Capital Stock);

     (iv) Limitation on Asset Sales.

     (A) Prior to the Effective Time, the Corporation will not, and will not
permit any of its Restricted Subsidiaries to, consummate an Asset Sale. From and
after the Effective Time, the Corporation will not, and will not permit any of
its Restricted Subsidiaries to, consummate an Asset Sale unless

          (1) the Corporation or such Restricted Subsidiary, as the case may be,
     receives consideration at the time of such sale or other disposition at
     least equal to the fair market value of the assets sold or otherwise
     disposed of;

          (2) not less than 80% of the consideration received by the Corporation
     or such Restricted Subsidiary, as the case may be, is in the form of cash
     or Cash Equivalents other than in the case where the Corporation is
     undertaking a Permitted Asset Swap; provided that the following will be
     deemed to be cash for purposes of this clause (2):

          Restricted Subsidiary's most recent balance sheet) of the Corporation
          or any Restricted Subsidiary (other than contingent liabilities) that
          are assumed by the transferee of any such assets pursuant to a
          customary novation agreement that releases the Corporation or such
          Restricted Subsidiary from further liability; and



                                     B-1-16


               (b) any securities, notes or other obligations received by the
          Corporation or any such Restricted Subsidiary from such transferee

          within 180 days after the applicable Asset Sale; and

          (3) the Asset Sale Proceeds received by the Corporation or such
     Restricted subsidiary are applied:

               (a) first, to the extent the Corporation or any such Restricted
          Subsidiary, as the case may be, elects, or is required, to prepay,
          repay or purchase Indebtedness under any then existing Indebtedness of
          the Corporation or any such Restricted Subsidiary within 180 days
          following the receipt of the Asset Sale Proceeds from any Asset Sale;
          provided that any such repayment, to the extent relating to revolving
          credit, must result in a permanent reduction of the commitments
          thereunder in an amount equal to the principal amount so repaid;

               (b) second, to the extent of the balance of Asset Sale Proceeds
          after application as described above, to the extent the Corporation
          elects, to an Investment in property or other assets (including
          Capital Stock or other securities purchased in connection with the
          acquisition of Capital Stock or property of another Person) in
          compliance with paragraph (k) (v) within 365 days following receipt of
          such Asset Sale Proceeds; and

               (c) third, if on such 180th day in the case of clause (3)(a) or
          on such 365th day in the case of clause (3)(b) with respect to any
          Asset Sale, the Available Asset Sale Proceeds exceed $5.0 million, the
          Corporation must apply an amount equal to the Available Asset Sale
          Proceeds to an offer to repurchase the Senior Preferred Stock (the
          "Excess Proceeds Offer"), at a purchase price in cash equal to 100% of
          the liquidation preference thereof plus, without duplication, an
          amount in cash equal to all accumulated and unpaid dividends
          (including Additional Dividends, if any) (including an amount in cash
          equal to a prorated dividend from the period from the Dividend Payment
          Date immediately prior to the Excess Proceeds Payment Date to the
          Excess Proceeds Payment Date (an "Excess Proceeds Purchase Price").

     (B) If an Excess Proceeds Offer is not fully subscribed, the Corporation
may retain the portion of the Available Asset Sale Proceeds not required to
repurchase Senior Preferred Stock.

     (C) If the Corporation is required to make an Excess Proceeds Offer, the
Corporation shall send by first-class mail, postage prepaid, within 30 days
following the date specified in clause (3)(c) above, a notice to each Holder of

     shall be a Business Day no earlier than 30 days and not later than 45 days
     from the date such notice in mailed (the "Excess Proceeds Payment Date"));

          (3) that any Senior Preferred Stock not tendered will continue to
     accumulate dividends;

          (4) that, unless the Corporation defaults in the payment of the Excess
     Proceeds Purchase Price, any Senior Preferred Stock accepted for payment
     pursuant to the Excess Proceeds Offer, shall cease to accumulate dividends
     after the Excess Proceeds Payment Date;

          (5) that Holders accepting the offer to have their Senior Preferred
     Stock purchased pursuant to an Excess Proceeds Offer will be required to
     surrender their the certificates representing the Senior Preferred Stock to
     the Corporation, properly endorsed for transfer together with such

     reasonably require, in the manner and at the address specified in the
     notice prior to the close of business on the Business Day preceding the
     Excess Proceeds Payment Date;

          (6) that Holders will be entitled to withdraw their acceptance of the
     Excess Proceeds Offer if the Corporation receives, not later than the close
     of business on the third Business Day preceding the Excess Proceeds Payment
     Date, a telegram, telex, facsimile transmission or letter setting forth the
     name of the Holder, the number of shares of Senior Preferred Stock
     delivered for purchase, and a statement that such Holder is withdrawing its
     election to have such Senior Preferred Stock purchased;

          (7) that if the aggregate liquidation preference of the Senior
     Preferred Stock surrendered by Holders exceeds the amount of Available
     Asset Sale Proceeds, the Corporation shall select the Senior Preferred
     Stock to be purchased on a pro rata basis;

          (8) that Holders whose Senior Preferred Stock are being purchased only
     in part will be issued new certificates representing the number of shares
     of Senior Preferred Stock equal to the unpurchased portion of the
     certificates surrendered;

          (9) the calculations used in determining the amount of Available Asset
     Sale Proceeds to be applied to the purchase of such Senior Preferred Stock;
     and

          (10) any other procedures that a Holder must follow to accept an
     Excess Proceeds Offer or effect withdrawal of such acceptance.

lawful, accept for payment, on a pro rata basis to the extent necessary, Senior
Preferred Stock or portions thereof tendered pursuant to the Excess Proceeds

                                     B-1-18


     (D) In the event of the transfer of substantially all of the property and
assets of the Corporation and its Restricted Subsidiaries as an entirety to a
Person in a transaction permitted under paragraph (f)(iii), the successor Person
shall be deemed to have sold the properties and assets of the Corporation and
its Restricted Subsidiaries not so transferred for purposes of this covenant,
and shall comply with the provisions of this covenant with respect to such
deemed sale as if it were an Asset Sale.

     (E) The Corporation will comply with the requirements of Rule 14e-1 under
the Exchange Act and other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the

the extent that the provisions of any securities laws or regulations conflict
with the provisions of this paragraph (k)(iv), the Corporation will comply with
the applicable securities laws and regulations and will not be deemed to have
breached its obligations under the provisions of this paragraph (k)(iv) by
virtue thereof.

     (v) Limitation on Conduct of Business. The Corporation and its Restricted
Subsidiaries will not engage in any businesses which are not the same, similar,

and its Restricted Subsidiaries are engaged in on the Issue Date.
Notwithstanding the foregoing, the Corporation may acquire and operate any
business which at the time of acquisition is primarily the same, similar,
ancillary or related to the businesses in which the Corporation and its
Restricted Subsidiaries are engaged in on the Issue Date. Notwithstanding the
foregoing, prior to the Effective Time, the Corporation shall not engage in any
business or activities other than holding the TTII Stock and activities related
thereto.

     (vi) Limitation on Sale and Lease-Back Transactions. The Corporation will
not, and will not permit any of its Restricted Subsidiaries to, enter into any
Sale and Lease-Back Transaction; provided that from and after the Effective Time

               (a) incurred Indebtedness (other than Permitted Indebtedness) in
          an amount equal to the Attributable Indebtedness relating to such Sale
          and Lease-Back Transaction under paragraph (k)(i); and

               (b) incurred a Lien to secure such Indebtedness pursuant to
          paragraph (k)(vii) (assuming solely for purposes of this clause (b)

Person, the ratio of EBITDA of such Person during the four full fiscal quarters
(the "Four Quarter Period") ending on or prior to the date of the transaction
giving rise to the need to calculate the Consolidated Fixed Charge Coverage
Ratio (the "Transaction Date") to Consolidated Fixed Charges of such Person for
the Four Quarter Period. In addition to and without limitation of the foregoing,
for purposes of this definition, "EBITDA" and "Consolidated Fixed Charges" shall
be calculated after giving effect on a pro forma basis for the period of such
calculation to

          (1) the incurrence or repayment of any Indebtedness of such Person or
     any of its Restricted Subsidiaries or the issuance or redemption or other

     redemption or other repayment, as the case may be (and the application of
     the proceeds thereof), occurred on the first day of the Four Quarter
     Period; and

          (2) any Asset Sale or Asset Acquisitions (including, without
     limitation, any Asset Acquisition giving rise to the need to make such
     calculation as a result of such Person or one of its Restricted
     Subsidiaries (including any Person who becomes a Restricted Subsidiary as a
     result of the Asset Acquisition) incurring, assuming or otherwise being
     liable for Acquired Indebtedness and also including any EBITDA (provided
     that such EBITDA shall be included only to the extent that Consolidated Net
     Income would be includable pursuant to the definition of "Consolidated Net
     Income") (including any pro forma expense and cost reductions calculated on
     a basis consistent with Regulation S-X of the Exchange Act) attributable to
     the assets which are the subject of the Asset Acquisition or Asset Sale
     during the Four Quarter Period) occurring during the Four Quarter Period or

     If such Person or any of its Restricted Subsidiaries directly or indirectly
     guarantees Indebtedness of a third Person, the preceding sentence shall
     give effect to the incurrence of such guaranteed Indebtedness as if such

               (1) interest on outstanding Indebtedness determined on a
          fluctuating basis as of the Transaction Date and which will continue
          to be so determined thereafter shall be deemed to have accrued at a
          fixed rate per annum equal to the rate of interest on such
          Indebtedness in effect on the Transaction Date;

               (2) if interest on any Indebtedness actually incurred on the
          Transaction Date may optionally be determined at an interest rate
          based upon a factor of a prime or similar rate, a eurocurrency

the payment in full of the IPO Redemption Price, all rights of the holders of
the Series C Preferred Stock to be redeemed shall terminate with respect

however, that if a notice of redemption shall have been given as provided in
Section 3(b) above and the funds (or property) necessary for redemption shall
have been irrevocably deposited in the trust for the equal and ratable benefit
for the holders of the shares of Series C Preferred Stock, then at the close of
business on the day on which such funds are segregated and set aside, the
holders of the shares to be redeemed shall cease to be stockholders of the
Corporation and shall be entitled only to receive the IPO Redemption Price.

     (e) Anything in this Certificate of Designations to the contrary
notwithstanding, the Corporation shall pay the IPO Redemption Price in respect
of the Series C Preferred Stock pursuant to this Section 3 with such types of
consideration such that the holders of Series C Preferred Stock shall receive:

          (i) an amount of cash equal to the sum of (A) the lesser of (x) the
     IPO Cash Excess, if any, and (y) the product of (1) the Maximum Liquidation
     Value and (2) a fraction, the numerator of which is the sum of the

     which is the IPO Cash Excess less the Cash paid in respect of the Series C
     Preferred Stock pursuant to the immediately preceding Clause (A), and the
     denominator of which is the sum of the Re-



                                      -2-


     deemed Series A Preferred Accreted Value, the Series A Preferred Accreted
     Value and the Maximum Liquidation Value, in each case immediately prior to
     the consummation of the IPO; and

          (ii) an amount of Common Stock (which shall be valued, per share, at
     the IPO Value) equal to the aggregate IPO Redemption Price over the amount
     of cash paid in redemption of the Series C Preferred Stock pursuant to this
     Section 3; provided that the Board of Directors may elect to pay cash
     instead of any non-cash consideration (based on the value of such non-cash
     consideration as so determined by the Board of Directors) otherwise so
     payable in respect of any share of the Series C Preferred Stock to any
     holder of Series C Preferred Stock, if it concludes that paying such
     non-cash consideration to such holder may create regulatory or compliance
     burdens on the part of the Corporation or any other participant in the
     transaction giving rise to such redemption event or is otherwise unable to
     pay such non-cash consideration.

     (f) Anything in this Section 3 to the contrary notwithstanding, the Board
of Directors may require that the holder of the Series C Preferred Stock execute
such agreements in respect of any non-cash consideration paid thereto upon
redemption as the Board of Directors may reasonably determine so long as the
holders of Series A Preferred Stock are also required to execute such agreements
in respect of such non-cash consideration; provided, that no holder of Series C
Preferred Stock shall be required to have liability under such agreements in
respect of breaches of representations and warranties in excess of the IPO
Redemption Price for such holders Series C Preferred Stock. Any holder's failure
to execute such agreement shall not affect the status of the Series C Preferred

                         Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware
         -------------------------------------------------------------


     Transportation Technologies Industries, Inc. (the "Corporation"), a
corporation organized and existing under the General Corporation Law of the
State of Delaware, does hereby certify that, pursuant to authority conferred
upon the board of directors of the Corporation (the "Board of Directors") by its
Certificate of Incorporation, as amended (hereinafter referred to as the
"Certificate of Incorporation"), and pursuant to the provisions of Section 151
of the General Corporation Law of the State of Delaware, said Board of
Directors, by unanimous written consent dated December 13, 2003, duly approved
and adopted the following resolution (the "Resolution"):

          RESOLVED, that, pursuant to the authority vested in the Board of
     Directors by the Corporation's Certificate of Incorporation, the Board of
     Directors does hereby create, authorize and provide for the issuance of 25%
     Senior Redeemable Preferred Stock, Series E, Par value $.01 per share, with
     a stated value of $l,000.00 per share, consisting of 41,475 shares, having
     the designations, preferences, relative, participating, optional and other
     special rights and the qualifications, limitations and restrictions thereof
     that are set forth in the Certificate of Incorporation and in this
     Resolution as follows:

     (a) Designation. There is hereby created out of the authorized and unissued
shares of Preferred Stock of the Corporation a class of Preferred Stock
designated as the "25% Senior Redeemable Preferred Stock." The number of shares
constituting such class shall be 41,475 and is referred to herein as the "Senior
Preferred Stock." The liquidation preference of the Senior Preferred Stock shall
be $1,000.00 per share (the "Liquidation Preference").

     (b) Rank. The Senior Preferred Stock shall, with respect to dividend
distributions and distributions upon liquidation, winding-up and dissolution of
the Corporation, rank (i) senior (to the extent set forth herein) to all classes
of Common Stock of the Corporation and to each other class of Capital Stock of
the Corporation or series of Preferred Stock of the Corporation now in existence
or hereafter created the terms of which do not expressly provide that it ranks
senior to, or on a parity with, the Senior Preferred Stock as to dividend
distributions and distributions upon redemption, liquidation, winding-up and
dissolution or Change of Control of the Corporation (collectively referred to,
together with all classes of Common Stock of the Corporation, as "Junior
Securities"); (ii) on a parity with any class of Capital Stock of the
Corporation or series of Preferred Stock of the Corporation hereafter created
the terms of which expressly provide that such class or series will rank on a
parity with the Senior Preferred Stock as to dividend distributions and
distributions upon liquidation, winding up and dissolution (collectively
referred to as "Parity Securities"), provided that any such Parity Securities
that were not





approved by the Holders in accordance with paragraph (f)(ii)(A) hereof shall be
deemed to be Junior Securities and not Parity Securities; and (iii) junior to
each other class of Capital Stock of the Corporation or series of Preferred
Stock of the Corporation hereafter created the terms of which expressly provide
that such class or series will rank senior to the Senior Preferred Stock as to
dividend distributions and distributions upon liquidation, winding-up and
dissolution of the Corporation (collectively referred to as "Senior
Securities"), provided that any such Senior Securities that were not approved by
the Holders in accordance with paragraph (f)(ii)(B) hereof shall be deemed to be
Junior Securities and not Senior Securities. The Senior Preferred Stock shall
rank senior to the outstanding 14 1/2% Senior Redeemable Preferred Stock of the
Corporation originally issued on March 9, 2000 (the "Existing Preferred Stock"),
the Series C Preferred Stock of the Corporation issued on December 18, 2003 (the
"Series C Preferred Stock") and the Series D Preferred Stock of the Corporation
issued on December 18, 2003 (the "Series D Preferred Stock") and shall
constitute "Senior Securities" under the "Certificate of Designations,
Preferences and Relative, Participatory, Optional and Other Special Rights of 14
1/2% Senior Redeemable Preferred Stock, Series A, and Qualifications,
Limitations and Restrictions Thereof" governing the terms of the Existing
Preferred Stock and "Senior Preferred Stock" under the "Certificate of
Designations, Number, Voting Powers, Preferences and Rights of Series C
Preferred Stock" governing the terms of the Series C Preferred Stock and the
"Certificate of Designations, Number, Voting Powers, Preferences and Rights of
Series D Preferred Stock" governing the terms of the Series D Preferred Stock.

     (c) Dividends.

     (i) From the Issue Date, the Holders of the outstanding shares of Senior
Preferred Stock shall be entitled to receive, when, as and if declared by the
Board of Directors, out of funds legally available therefor, dividends on each
share of Senior Preferred Stock at a rate per annum equal to 25% of the
Liquidation Preference per share of Senior Preferred Stock. All dividends shall
be cumulative, whether or not earned or declared, on a daily basis from the
Issue Date and shall be payable semi-annually in arrears on each Dividend
Payment Date, commencing on the first Dividend Payment Date after the Issue
Date. All unpaid dividends will compound on a semi-annual basis at a rate per
annum equal to the then applicable dividend rate. Dividends shall be payable in
cash (when, as and if declared by the Board of Directors out of funds legally
available therefor). Each dividend shall be payable to the Holders of record as
they appear on the stock books of the Corporation on the Dividend Record Date
immediately preceding the related Dividend Payment Date.

     (ii) All dividends paid with respect to shares of the Senior Preferred
Stock pursuant to paragraph (e)(i) shall be paid pro rata to the Holders
entitled thereto.

     (iii) Dividends accruing on the Senior Preferred Stock for any past
Dividend Period may be declared and paid at any time, without reference to any
Dividend Payment Date to Holders of record on such date, not more than ten (10)
days prior to the payment hereof as may be fixed by the Board of Directors.

     (iv) (A) No full dividends shall be declared by the Board of Directors or
paid or set apart for payment by the Corporation on any Parity Securities for
any period unless full cumulative dividends have been or contemporaneously are
declared and paid in full, or declared



                                      -2-


and a sum in cash set apart sufficient for such payment, on the Senior Preferred
Stock for all Dividend Periods terminating on or prior to the date of payment of
such full dividends on such Parity Securities. If any dividends are not so paid,
all dividends declared upon shares of the Senior Preferred Stock and any other
Parity Securities shall be declared pro rata so that the amount of dividends
declared per share on the Senior Preferred Stock and such Parity Securities
shall in all cases bear to each other the same ratio that accrued dividends per
share on the Senior Preferred Stock and such Parity Securities bear to each
other.

     (B) So long as any share of the Senior Preferred Stock is outstanding, the
Corporation shall not declare, pay or set apart for payment any dividends on any
of the Junior Securities (other than dividends in the form of the same class of
Junior Securities), or make any payment on account of, or set apart for payment
money for a sinking or other similar fund for, the purchase, redemption or other
retirement of, any of the Junior Securities or any warrants, rights, calls or
options exercisable for or convertible into any of the Junior Securities whether
in cash, obligations or shares of the Corporation or other property (other than
in exchange for Junior Securities), and shall not permit any corporation or
other entity directly or indirectly controlled by the Corporation to purchase or
redeem any of the Junior Securities or any such warrants, rights, calls or
options (other than in exchange for Junior Securities).

     (C) So long as any share of the Senior Preferred Stock is outstanding, the
Corporation shall not (except with respect to dividends as permitted by
paragraph (c)(iv)(A)) make any payment on account of, or set apart for payment
money for a sinking or other similar fund for, the purchase, redemption or other
retirement of, any of the Parity Securities or any warrants, rights, calls or
options exercisable for or convertible into any of the Parity Securities whether
in cash, obligations or shares of the Corporation or other property, and shall
not permit any corporation or other entity directly or indirectly controlled by
the Corporation to purchase or redeem any of the Parity Securities or any such
warrants, rights, calls or options.

     (v) Dividends payable on the Senior Preferred Stock for any period less
than a year shall be computed on the basis of a 360-day year of twelve 30-day
months and, for periods not involving a full calendar month, the actual number
of days elapsed (not to exceed 30 days).

     (d) Liquidation Preference.

     (i) In the event of any voluntary or involuntary liquidation, dissolution
or winding-up of the affairs of the Corporation, the Holders of shares of Senior
Preferred Stock then outstanding shall be entitled to be paid out of the assets
of the Corporation available for distribution to its stockholders an amount in
cash equal to the Liquidation Preference for each share outstanding, plus,
without duplication, an amount in cash equal to accumulated and unpaid dividends
thereon to the date fixed for liquidation, dissolution or winding-up (including
an amount equal to a prorated dividend for the period from the last Dividend
Payment Date to the date fixed for liquidation, dissolution or winding-up)
before any distribution shall be made or any assets distributed in respect of
Junior Securities to the holders of any Junior Securities including, without
limitation, Common Stock of the Corporation. If upon any voluntary or
involuntary liquidation, dissolution or winding-up of the Corporation, the
amounts payable with respect to the Senior Preferred Stock and all other Parity
Securities are not paid in full, the Holders of the Senior Preferred Stock and
the Parity Securities will share equally and ratably in any distribution of
as-



                                      -3-


sets of the Corporation first in proportion to the full liquidation preference
to which each is entitled until such preferences are paid in full, and then in
proportion to their respective amounts of accumulated but unpaid dividends.

     (ii) For the purposes of this paragraph (d), neither the sale, conveyance,
exchange or transfer (for cash, shares of stock, securities or other
consideration) of all or substantially all of the property or assets of the
Corporation nor the consolidation or merger of the Corporation with or into one
or more entities shall be deemed to be a liquidation, dissolution or winding-up
of the affairs of the Corporation.

     (e) Redemption.

     (i) Optional Redemption. (A) The Corporation may redeem the Senior
Preferred Stock at its option in whole at any time or in part from time to time,
on or after the Issue Date, subject to contractual and other restrictions with
respect thereto, from any source of funds legally available therefor, in the
manner provided for in paragraph (e)(ii) hereof, at the redemption prices in
cash (expressed as a percentage of the Liquidation Preference) set forth below,
plus, without duplication, an amount in cash equal to all accumulated and unpaid
dividends (including an amount in cash equal to a prorated dividend for the
period from the Dividend Payment Date immediately prior to the Redemption Date
to the Redemption Date) if redeemed during the 12-month period beginning on each
date listed below:

          Issue Date - December 31, 2004...................      118.75%
          January 1, 2005 - December 31, 2009..............      112.50%
          January 1, 2010 - December 31, 2010..............      106.25%
          January 1, 2011 and thereafter...................      100.00%

; provided that no redemption pursuant to this paragraph (e)(i)(A) shall be
authorized or made unless prior thereto full accumulated and unpaid dividends
are declared and paid in full, or declared and a sum in each is set apart
sufficient to such payment, on the Senior Preferred Stock for all Dividend
Periods terminating on or prior to the Redemption Date.

     (B) In the event of a redemption pursuant to paragraph (e)(i)(A) hereof of
only a portion of the then outstanding shares of Senior Preferred Stock, the
Corporation shall effect such redemption on a pro rata basis according to the
number of shares held by each Holder of Senior Preferred Stock, except that the
Corporation may redeem such shares held by Holders of fewer than one share (or
shares held by Holders who would hold less than one share as a result of such
redemption), as may be determined by the Corporation.

     (ii) Procedures for Redemption. (A) At least 15 days and not more than 90
days prior the date fixed for any redemption of the Senior Preferred Stock,
written notice (the "Redemption Notice") shall be given by first-class mail,
postage prepaid, to each Holder of record on the record date fixed for such
redemption of the Senior Preferred Stock at such Holder's address as it appears
in the register maintained by the transfer agent for the Senior Preferred Stock,
provided that no failure to give such notice nor any deficiency therein shall
affect the validity of the procedure for the redemption of any shares of Senior
Preferred Stock to be redeemed



                                      -4-


except as to the Holder or Holders to whom the Corporation has failed to give
said notice or except as to the Holder or Holders whose notice was defective.
The Redemption Notice shall state:

          (1) that the redemption is pursuant to paragraph (e)(i)(A) hereof;

          (2) the redemption price;

          (3) whether all or less than all the outstanding shares of Senior
     Preferred Stock are to be redeemed and the total number of shares of Senior
     Preferred Stock being redeemed;

          (4) the Redemption Date;

          (5) that the Holder is to surrender to the Corporation, in the manner,
     at the place or places and at the price designated, his certificate or
     certificates representing the shares of Senior Preferred Stock to be
     redeemed; and

          (6) that dividends on the shares of Senior Preferred Stock to be
     redeemed shall cease to accumulate on such Redemption Date unless the
     Corporation defaults in the payment of the redemption price.

     (B) Each Holder of Senior Preferred Stock shall surrender the certificate
or certificates representing such shares of Senior Preferred Stock to the
Corporation, duly endorsed (or otherwise in proper form for transfer, as
determined by the Corporation), in the manner and at the place designated in the
Redemption Notice, and on the Redemption Date the full redemption price for such
shares shall be payable in cash to the Person whose name appears on such
certificate or certificates as the owner thereof, and each surrendered
certificate shall be canceled and retired. In the event that less than all of
the shares represented by any such certificate are redeemed, a new certificate
shall be issued on the Redemption Date representing the unredeemed shares.

     (C) On and after the Redemption Date, unless the Corporation defaults in
the payment in full of the applicable redemption price, dividends on Senior
Preferred Stock called for redemption shall cease to accumulate on the
Redemption Date, and all rights of the Holders of redeemed shares shall
terminate with respect thereto on the Redemption Date, other than the right to
receive the redemption price; provided, however, that if a notice of redemption
shall have been given as provided in paragraph (ii)(A) above and the funds
necessary for redemption (including an amount in cash in respect of all
dividends that will accumulate to the Redemption Date) shall have been
irrevocably deposited in trust for the equal and ratable benefit for the Holders
of the shares of Senior Preferred Stock to be redeemed, then, at the close of
business on the Business Day on which such funds are segregated and set aside,
the Holders of the shares to be redeemed shall cease to be stockholders of the
Corporation and shall be entitled only to receive the redemption price.

          (f) Voting Rights.

     (g) Change of Control.

     (i) in connection with, and as part of and as a condition to the
effectiveness of, a Change of Control (the date of such occurrence being the
"Change of Control Date"), the Corporation shall redeem the outstanding shares
of Senior Preferred Stock tendered for redemption at a purchase price equal to
the Applicable Redemption Price plus, without duplication, an amount in cash
equal to all accumulated and unpaid dividends thereon (including an amount in
cash equal to a prorated dividend for the period from the immediately preceding
Dividend Payment Date to the Change of Control Payment Date) (the "Change of
Control Purchase Price"), such amount to be payable in cash, and no payment
shall be made to the holders of the Common Stock, Junior Securities or any other
capital stock ranking with regard to dividend rights, rights upon liquidation or
a Change of Control or redemption rights junior to the Senior Preferred Stock
unless such amount is paid in full.

     The Corporation shall not participate in any Change of Control or make or
agree to have made any payments to the holders of Junior Securities or shares of
Common Stock or any other class or series of capital stock of the Corporation
ranking in a Change of Control on a parity with the Senior Preferred Stock
unless the holders of Senior Preferred Stock shall have received the full
preferential amount to which they are entitled hereunder in a Change of Control.

     (ii) Not less than fifteen (15) days prior to the occurrence of a Change of
Control, the Corporation shall send by first-class mail, postage prepaid, to
each Holder of Senior Preferred Stock, at the address appearing in the register
maintained by the transfer agent for the Senior Preferred Stock, a notice (the
"Change of Control Offer") stating:

          (1) that the Change of Control Offer is being made pursuant to this
     paragraph (g) and that all of the Senior Preferred Stock tendered will be
     accepted for payment, and otherwise subject to the terms and conditions set
     forth herein;

          (2) the Change of Control Purchase Price and the date proposed for the
     Change of Control (which shall be a Business Day no later than 30 days from
     the date such notice if mailed);

          (3) that any of the Senior Preferred Stock not tendered will continue
     to accumulate dividends;

          (4) that, unless the Corporation defaults in the payment of the Change
     of Control Purchase Price, any of the Senior Preferred Stock accepted for
     payment pursuant to the Change of Control Offer shall cease to accumulate
     dividends after the Change of Control;



                                      -8-


          (5) that Holders accepting the offer to have their Senior Preferred
     Stock purchased pursuant to a Change of Control Offer will be required to
     surrender their certificates representing the Senior Preferred Stock to the
     Corporation, properly endorsed for transfer together with such customary
     documents as the Corporation and the transfer agent may reasonably require,
     in the manner and at the address specified in the notice prior to the close
     of business on the Business Day preceding the Change of Control;

          (6) that Holders will be entitled to withdraw their acceptance if the
     Corporation receives, not late than the close of business on the third
     Business Day preceding the Change of Control, a telegram, telex, facsimile
     transmission or letter setting forth the name of the Holder, the number of
     shares of Senior Preferred Stock delivered to purchase, and a statement
     that such Holder is withdrawing its election to have such Senior Preferred
     Stock purchased;

          (7) that Holders whose shares of Senior Preferred Stock are being
     purchased only in part will be issued new certificates representing the
     number of shares of Senior Preferred Stock equal to the unpurchased portion
     of the certificates surrendered; and

          (8) any other reasonable procedures that a Holder must follow to
     accept a Change of Control Offer or effect withdrawal of such acceptance.

          (iii) The Corporation will comply with the requirements of Rule 14e-1
     under the Exchange Act and any other securities laws and regulations
     thereunder to the extent such laws and regulations are applicable in
     connection with the repurchase of shares of Senior Preferred Stock pursuant
     to a Change of Control Offer. To the extent that the provisions of any
     securities laws or regulations conflict with the provisions of this
     paragraph (g), the Corporation will comply with the applicable securities
     laws and regulations and will not be deemed to have breached its
     obligations under this paragraph (g) by virtue thereof.

          (iv) On the Change of Control, the Corporation shall (A) accept for
     payment the shares of Senior Preferred Stock validly tendered pursuant to
     the Change of Control Offer, (B) mail to the Holders of shares so accepted
     the Change of Control Purchase Price therefor in cash and (C) cancel and
     retire each surrendered certificate and execute a new certificate
     representing that number of shares of Senior Preferred Stock equal to any
     unpurchased shares represented by a certificate surrendered. Unless the
     Corporation defaults in the payment for the shares of Senior Preferred
     Stock, tendered pursuant to the Change of Control Offer, dividends shall
     cease to accumulate with respect to the shares of Senior Preferred Stock
     tendered and all rights of Holders of such tendered shares shall terminate,
     except for the right to receive payment therefor, upon the Change of
     Control.

     (h) No Avoidance. The Corporation shall not, by amendment to its
Certificate of Incorporation or this Resolution and Certificate Designation (by
way of merger, consolidation, operation of law, or otherwise) or through any
Change of Control or other reorganization, transfer of assets, consolidation,
merger, dissolution, issuance or sale of securities, agreement or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation and shall at
all times in good faith as-



                                      -9-


sist in the carrying out of all the provisions of this Certificate of
Designation and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the holders of the Senior
Preferred Stock against impairment. Any successor to the Corporation shall agree
in writing, as a condition to such succession, to carry out and observe the
obligations of the Corporation hereunder with respect to the Senior Preferred
Stock.

     (i) Contractual Rights of Holders. The various provisions set forth herein
for the benefit of the holders of the Senior Preferred Stock shall be deemed
contract rights enforceable by them, including, without limitation, one or more
actions for specific performance.

     (j) Conversion or Exchange. The Holders of shares of Senior Preferred Stock
shall not have any rights hereunder to convert such shares into or exchange such
shares for shares of any other class or classes or of any other series of any
