         A.   AUTHORIZED CAPITAL STOCK.  The total number of shares which the
Corporation shall have authority to issue is two hundred thousand (200,000)
shares, with each 



share having a par value of one cent ($0.01).  These shares shall be divided

Class A Voting Common Stock (the "CLASS A COMMON STOCK"); and (ii) one hundred
thousand (100,000) shares of Class B Supervoting Common Stock (the "CLASS B
COMMON STOCK" and, together with the Class A Common Stock, the "COMMON STOCK").

         B.   RIGHTS AND PRIVILEGES.  Except as otherwise provided herein, all
shares of Class A Common Stock and Class B Common Stock will be identical and
will entitle the holder thereof to the same rights and privileges.

              (1)  VOTING RIGHTS.  

                   (a)       The holders of Class A Common Stock will be
entitled to one vote per share on all matters to be voted on by the
Corporation's stockholders.  

                   (b)       Until one of the events described in subsections
(i) through (iv) below (each, a "VOTING EVENT") shall have occurred, the holders
of Class B Common Stock will be entitled to ten votes per share on all matters
to be voted upon by the Corporation's stockholders.  Following the occurrence of
a Voting Event, the holders of Class B Common Stock will be entitled to one vote
per share on all matters to be voted on by the Corporation's stockholders.

                        (i)     The Corporation  (A) shall commence any
proceeding under any bankruptcy, reorganization, arrangement, readjustment of
debt, dissolution or liquidation law or statute of any jurisdiction, whether now
or hereafter in effect; or (B) shall have had any such petition or application
filed or any such proceeding shall have been commenced, against it, in which an
adjudication or appointment is made or order for relief is entered, or which

or more;

                        (ii)    (A) Michael J. Hartnett shall die or (B) ninety

functions, taken as a whole, of his position as Chief Executive Officer of the
Corporation and/or of its wholly owned subsidiaries;

                        (iii)   At such time that Michael J. Hartnett and his
Permitted Transferees shall have the power to vote with respect to, or the power
to dispose of, less than 50% of the shares of the Common Stock, on a fully
diluted basis (i.e., assuming full exercise of all such holders' warrants,
options and other rights to purchase shares of Common Stock), owned by
Michael J. Hartnett on the date hereof (as adjusted to allow for subdivisions
and combinations of Common Stock, stock dividends and other similar dilution
events); and 

                        (iv)    the first underwritten public offering of
equity securities of the Corporation pursuant to an effective registration
statement under the Securities 

                                         -2-




Act of 1933, as amended, for which the Corporation shall have received not less
than $25 million in gross proceeds and following which there is a public market
for the securities so offered.

         For the purposes of this subsection (iii), "Permitted Transferee"
shall mean, with respect to any Person, (i) if such Person is an individual, (A)
a member of the Immediate Family of such Person, or (B) a trust or other similar
legal entity for the primary benefit of such Person and/or one or more members
of his Immediate Family, or (C) a partnership, limited partnership, limited
liability company, corporation or other entity in which such Person and members

corporation, any wholly owned subsidiary or parent of such corporation that
wholly owns such corporation.  For purposes of this definition, "Immediate
Family", with respect to any individual, shall mean his brothers, sisters,
spouse, children (including adopted children), parents, parents-in-law,
grandchildren, great grandchildren and other lineal descendants and spouses of
any of the foregoing.

                   (c)  Notwithstanding the foregoing, the affirmative vote of
a majority of the outstanding shares of Class A Common Stock and Class B Common
Stock, each voting as a class, shall be required in respect of 

                        (i)     any modification of any kind or nature
whatsoever to the bylaws of the Corporation or the Certificate of Incorporation
of the Corporation if such modification would adversely affect the rights and
entitlements of the holders of shares of such class as then set forth in such
bylaws or Certificate of Incorporation, or 

                        (ii)    a merger or consolidation involving the
Corporation, or a sale of all or substantially all of the assets of the
Corporation and its subsidiaries, taken as a whole, in any such case if by
reason thereof the holders of Common Stock, regardless of class (A) do not
receive equivalent per share consideration (i.e. as among themselves), or (B)
receive consideration other than cash and/or securities that are listed on the
New York Stock Exchange, the American Stock Exchange or the NASDAQ National
Market.

              (2)  DIVIDENDS.  When, as and if dividends are declared, whether
payable in cash, property or securities of the Corporation, the holders of both
Class A Common Stock and Class B Common Stock will be entitled to receive such
dividends, ratably according to the number of shares of Common Stock held by
them.

              (3)  LIQUIDATION RIGHTS.  In the event of any liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary,
the holders of Class A Common Stock and Class B Common Stock shall be entitled
to share, ratably according to the number of shares of Common Stock held by
them, in the assets of the Corporation available for distribution to its
stockholders.  

                                         -3-




              (4)  CONVERSION OF CLASS B COMMON STOCK.  

                   (a)  At any time and from time to time, each record holder
of Class B Common Stock will be entitled to convert any and all of the shares of
such holder's Class B Common Stock into shares of Class A Common Stock on a one
to one basis at such holder's election.

                   (b)  At any time and from time to time that Michael J.
Hartnett or any Permitted Transferee of Michael J. Hartnett shall transfer any
shares of Class B Common Stock other than to a Permitted Transferee such shares
of Class B Common Stock so transferred will automatically and without any
further action be deemed to have been converted into shares of Class A Common
Stock on a one-to-one basis.  Upon any such transfer, such holder of shares of
Class B Common Stock shall be obligated to effect the procedures described in
paragraphs (c) through (f) below; provided, however, that such conversion shall
be deemed to have occurred regardless of such holder's compliance therewith.

                   (c)  Each conversion of shares of Class B Common Stock into
shares of Class A Common Stock will be effected by the surrender of the
certificate or certificates representing the shares to be converted at the
principal office of the Corporation (or such other office or agency of the
Corporation as the Corporation may designate by notice in writing to the holder
or holders of the Class B Common Stock) at any time during normal business
hours, together with a written notice by the Holder of such Class B Common Stock
stating that such holder desires to convert the shares, or a stated number of
the shares, of Class B Common Stock represented by such certificate or
certificates into Class A Common Stock.  Such conversion will be deemed to have
been effected as of the close of business on the date on which 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 B Common Stock as such
will cease and the person or persons in whose name or names the certificate or
certificates for shares of Class A Common Stock are to be issued upon such
conversion will be deemed to have become the holder or holders of record of the
shares of Class A Common Stock represented thereby.

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

                   (e)  The Corporation will at all times reserve and keep
available out of its authorized but unissued shares of Class A Common Stock or
its treasury shares, solely for the purpose of issue upon the conversion of the
Class B Common Stock as provided in this Section (B)(4), such number of shares
of Class A Common Stock as shall then be issuable upon the conversion of all
then outstanding shares of Class B Common Stock.

                   (f)  The issuance of certificates for Class A Common Stock
upon the conversion of Class B Common Stock will be made without charge to the
holders of such 

                                         -4-




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
A Common Stock.  The Corporation will not close its books against the transfer
of Class B Common Stock or of Class A Common Stock issued or issuable upon the
conversion of Class B Common Stock in any manner which would interfere with the
timely conversion of Class B Common Stock.

              (5)  PREEMPTIVE RIGHTS.  No holder of shares of Common Stock
shall be entitled to the preemptive right to subscribe to any or all additional
issues of stock of the Corporation of any or all classes or series thereof, or
to any securities of the Corporation convertible into, or exchangeable or
exercisable for, such stock, except to the extent set forth in the Stockholders'
Agreement, dated as of June 23, 1997, by and among the Corporation and certain
of its stockholders, as the same may be amended from time to time.

              (6)  BUSINESS COMBINATIONS WITH INTERESTED STOCKHOLDERS.  The
Corporation shall not be governed by the provisions of Section 203 of the
Delaware General Corporation Law.

         FIFTH:  Amendment of Bylaws.

         In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized to make, repeal, alter,
amend and rescind the bylaws of the Corporation, subject to the receipt of the
requisite vote of the stockholders, if any, pursuant to Article Fourth above.

         SIXTH:  Election of Directors.

         Elections of directors need not be by written ballot unless the bylaws
of the Corporation shall so provide.

         SEVENTH:  Amendment of Certificate of Incorporation.

         Subject to the receipt of the requisite vote of the stockholders, if
any, pursuant to Article Fourth above, the Corporation reserves the right to
amend, alter, change or repeal any provision contained in this 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.

         EIGHT:  Liability and Indemnification.

         A.   The Corporation shall indemnify, in the manner and to the full
extent permitted by law, any person (or the estate of any person) who was or is
a party to, or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether or not by or in the right of the
Corporation, and whether civil, criminal, administrative, investigative or
otherwise, by reason of the fact that such person is or was a director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee, agent or fiduciary of another
corporation, 

                                         -5-




partnership, joint venture, trust or other enterprise.  The Corporation may, to
the full extent permitted by law, purchase and maintain insurance on behalf of
any such person against any liability which may be asserted against him.  To the
full extent permitted by law, the indemnification provided herein shall include
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement, and, in the manner provided by law, any such expenses shall be paid
by the Corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of the person seeking
indemnification to pay such amounts if it is ultimately determined that he is
not entitled to be indemnified.  The indemnification provided herein shall not
be deemed to limit the right of the Corporation to indemnify any other person
for any such expenses to the full extent permitted by law, nor shall it be
deemed exclusive of any other rights to which any person seeking indemnification
from the Corporation may be entitled under any agreement, vote of stockholders
or disinterested directors or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office.

         B.   A director of the Corporation shall not be liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except to the extent such exemption from liability or
limitation thereof is not permitted under the Delaware General Corporation Law
as the same exits or may hereafter be amended.

         C.   Any repeal or modification of Section B of this Article EIGHTH
shall not adversely affect any right or protection of a director of the
Corporation existing hereunder with respect to any act or omission occurring
prior to such repeal or modification.

         IN WITNESS WHEREOF, the undersigned has executed this Amended and
Restated Certificate of incorporation on behalf of the Corporation and does
hereby verify and affirm, under penalty of perjury, that this Amended and
Restated Certificate of Incorporation is the act and deed of the Corporation and
that the facts stated herein are true as of June 23, 1997.
