requirements of law and any other provision of this Restated Certificate of
Incorporation or any resolution or resolutions of the Board of Directors adopted

         EIGHTH: To the fullest extent that the General Corporation Law of the
State of Delaware or any other law of the State of Delaware as it exists on the
date hereof or as it may hereafter be amended permits the limitation or
elimination of the liability of directors, no director of the Corporation shall
be liable to the Corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director. No amendment to, or modification or repeal of,

be required notwithstanding the fact that no vote may be required, or that a
lesser percentage or separate class vote may be specified, by law, by any other
provision of this Restated Certificate of Incorporation or the Bylaws of the
Corporation, by any agreement with any national securities exchange or
otherwise.

not be applicable to any particular Business Combination, and such Business
Combination shall require only such affirmative vote, if any, as is required by
law, by any other provision of this Restated Certificate of Incorporation or

                      transaction that has the effect of reducing the number of
                      outstanding shares of Common Stock, unless the failure so
                      to increase the amount of such dividends is approved by a
                      majority of the Continuing Directors; and (z) such
                      Interested Stockholder shall not have become the

                      of related transactions) and except in a transaction or
                      series of related transactions that, after giving effect

                      of any class or series of Capital Stock.

                      Interested Stockholder shall not have received the

                      Corporation at least 30 days prior to the consummation of

                      information statement is required to be mailed pursuant to

                      any statement as to the advisability (or inadvisability)
                      or the Business Combination that the Continuing Directors,
                      or any of them, may choose to make and, if deemed

                      Stockholder and its Affiliates or Associates, such
                      investment banking firm to be paid a reasonable fee for

                      Interested Stockholder shall not have made any majority
                      change in the Corporation's business or capital structure
                      without the approval of a majority of the Continuing

         TENTH:   (a) In addition to any affirmative vote required by law or by
this Restated Certificate of Incorporation or the Bylaws of the Corporation, and
except as otherwise expressly provided in Section (b) of this Article TENTH, the
Corporation shall not knowingly engage, directly or indirectly, in any Stock
Repurchase (as hereinafter defined) from an Interested Stockholder (as
hereinafter defined), who has been such for a period of less than two years

without the affirmative vote of a majority of the votes entitled to be cast by
the holders of all then outstanding shares of Voting Stock which are
beneficially owned by persons other than such Interested Stockholder, voting
together as a single class. Such affirmative vote shall be required
notwithstanding the fact that no vote may be required, or that a lesser

with any national securities exchange or otherwise.

                  (b) The provisions of Section (a) of this Article TENTH shall

Stockholder, and such Stock Repurchase shall require only such affirmative vote,
if any, as is required by law or by any other provision of this Restated
Certificate of Incorporation or the Bylaws of the Corporation, or any agreement
with any national securities exchange, if: (i) the Stock Repurchase is made
pursuant to a tender offer or exchange offer for a class of Capital Stock (as
defined in Article NINTH of this Restated Certificate of Incorporation) made
available on the same basis to all holders of such class of Capital Stock; or
(ii) the Stock Repurchase is made pursuant to an open market purchase program
approved by a majority of the Continuing Directors (as defined in Article NINTH
of this Restated Certificate of Incorporation), provided that such repurchase is
effected on the open market and is not the result of a privately negotiated
transaction.

                  (c) For the purposes of this Article TENTH:

                      (i)     The term "Stock Repurchase" shall mean any
repurchase, directly or indirectly, by the Corporation or any Subsidiary of any
shares of Capital Stock at a price greater than the then Fair Market Value of
such shares.

                      (ii)    The term "Interested Stockholder" shall mean any
person (other than the Corporation or any Subsidiary and other than any

Corporation or any Subsidiary or any trustee of or fiduciary with respect to any
such plan when acting in such capacity) who (A) is the beneficial owner of
Voting Stock representing five percent (5%) or more of the votes entitled to be
cast by the holders of all then outstanding shares of Voting Stock; or (B) is an
Affiliate or Associate of the Corporation and at any time within the two-year

owner of Voting Stock representing five percent (5%) or more of the votes
entitled to be cast by the holders of all then outstanding shares of Voting
Stock.

                      (iii)   The terms "person," "beneficial owner,"
"Affiliate," "Associate," "Subsidiary," "Continuing Director" and "Fair Market
Value" shall have the respective meanings set forth in Article NINTH of this
Restated Certificate of Incorporation.

                  (d) The Board of Directors shall have the power and duty to
determine for the purposes of this Article TENTH, on the basis of information
known to them after reasonable inquiry, (i) whether a person is an Interested
Stockholder, (ii) the number of shares of Capital Stock or other securities
beneficially owned by any person, (iii) whether a person is an Affiliate or
Associate of another and (iv) whether the consideration to be paid in any Stock
Repurchase has an aggregate Fair Market Value in excess of the then Fair Market
Value of the shares of Capital Stock being repurchased. Any such determination
made in good faith shall be binding and conclusive on all parties.

                  (e) Nothing contained in this Article TENTH shall be construed
to relieve any Interested Stockholder from any fiduciary obligation imposed by
law.

         ELEVENTH:(a) Except as set forth in this Article ELEVENTH,
stockholders of the Corporation shall not be entitled to cumulative voting in
connection with the election of directors. In the event that the Corporation has
a Substantial Stockholder (as hereinafter defined) at the time of any election
of directors, each holder of Voting Stock (as defined in Article FIFTH of this
Restated Certificate of Incorporation) shall be entitled, in connection with any
vote taken for such election of directors, to as many votes as shall equal the
number of votes which (except for this Article ELEVENTH) such stockholder would
be entitled to cast for the election of directors with respect to such
stockholder's shares of Voting Stock multiplied by the number of directors to be
elected by such stockholder, and such stockholder may cast all of such votes for
election of a single director or may distribute them among the number of
directors to be voted for, or for any two or more of them as such stockholder
may see fit.

Stock representing forty percent (40%) or more of the votes entitled to be cast
by the holders of all then outstanding shares of Voting Stock.

                                       13



                      (ii)    The terms "beneficial owner," "Capital Stock,"
"person," "Affiliate," "Associate," "Subsidiary," "Fair Market Value" and

Restated Certificate of Incorporation.

                  (c) The Board of Directors shall have the power and duty to
determine for the purposes of this Article ELEVENTH on the basis of information
known to them after reasonable inquiry, (i) whether a person is a Substantial
Stockholder, (ii) the number of shares of Voting Stock or other securities
beneficially owned by any person, and (iii) whether a person is an Affiliate or
Associate of another. Any such determination made in good faith shall be binding
and conclusive on all parties.

                  (d) Nothing contained in this Article ELEVENTH shall be
construed to relieve any Substantial Stockholder from any fiduciary obligation
imposed by law.

         TWELFTH: The Board of Directors of the Corporation, when evaluating any
offer to (a) make a tender or exchange offer for any equity security of the
Corporation, (b) merge or consolidate the Corporation with another person, or

assets of the Corporation (an "Acquisition Proposal"), shall, in connection with
the exercise of its business judgment, give due consideration to all relevant
factors, including without limitation the social and economic effects thereof
and of consummation thereof on the employees, customers, suppliers and other
constituents of the Corporation and its subsidiaries and on the communities in
which the Corporation and its subsidiaries operate or are located and the
desirability of maintaining independence from any other entity which is a
customer or competitor of the Corporation.

         THIRTEENTH: In addition to any requirements of law and any other
provisions of this Restated Certificate of Incorporation or any resolution or
resolutions of the Board of Directors adopted pursuant to Article FOURTH of this
Restated Certificate of Incorporation (and notwithstanding the fact that a
lesser percentage may be specified by law, this Restated Certificate of
Incorporation or any such resolution or resolutions), the affirmative vote of
the holders of 80% or more of the combined voting power of the then outstanding
shares of Voting Stock, voting together as a single class, shall be required to
amend, alter or repeal ARTICLES FIFTH, SIXTH, SEVENTH, EIGHTH, NINTH, TENTH,
ELEVENTH, TWELFTH and THIRTEENTH of this Restated Certificate of Incorporation.
Subject to the foregoing provisions of this Article THIRTEENTH, the Corporation
reserves the right to amend, alter or repeal any provision contained in this
Restated Certificate of Incorporation in the manner now or hereinafter
prescribed by statute, and all rights conferred upon stockholders herein are
subject to this reservation.
