                                   ARTICLE IV

                                      STOCK

                                   Section 1.

                  Common Stock. The Board of Directors of the Corporation may,
from time to time, distribute on a pro rata basis to its Common Stock
shareholders, out of the capital surplus of the Corporation, a portion of its
assets, in cash or property.

                  The Board of Directors of the Corporation may, from time to
time, cause the Corporation to purchase its own Common Stock shares to the
extent of the unreserved and unrestricted earned and capital surplus of the
Corporation.

                  The Corporation may issue rights and options to purchase
shares of Common Stock of the Corporation to Directors, Officers or employees of
the Corporation or any affiliate thereof, and no shareholder approval or
ratification of any such issuance of rights and options shall be required.

                                   Section 2.

                  Preferred Stock. The Corporation shall have authority to issue
its Preferred Stock in series. The Board of Directors is vested with authority
to establish and designate series and to fix the number of shares to be included
in each such series and the relative rights, preferences and limitations of each
such series, subject to the provisions set forth below. If the stated dividends
and amounts payable on liquidation are not paid in full, the shares of all
series of the same class shall share ratably in the payment of dividends
including accumulations, if any, in accordance with the sums which would be
payable on such shares if all dividends were declared and paid in full, and in
any distribution of assets other than by way of dividends in accordance with the
sums which would be payable in such distribution if all sums payable were
discharged in full. The authority of the Board of Directors with respect to each
series of Preferred Stock shall include, but not be limited to, determination of
the following:

                           a. The number of shares constituting that series and
the distinctive designation of that series;

   3
                           b. The dividend rate on the shares of that series,
whether dividends shall be cumulative, and, if so, from which date or dates;

                           c. Whether that series shall participate in unlimited
dividend rights, and, if so, the extent of such participation;

                           d. Whether that series shall have voting rights, in
addition to the voting rights provided by law, and, if so, the terms of such
voting rights, including whether it shall vote as a separate series, or with
other series of Preferred Stock, or as one class with the holders of Common
Stock, with or without other series of Preferred Stock, and whether differently
as to different matters, or any combination of the foregoing;

                           e. Whether that series shall have conversion
privileges, and, if so, the terms and conditions of such conversion, including
provision for adjustment of the conversion rate in such events as the Board of
Directors shall determine;

                           f. Whether or not the shares of that series shall be

limitations of that series.

                  Dividends on outstanding Preferred Stock of each series shall
be declared and paid, or set apart for payment, before any dividends shall be
declared and paid, or set apart for payment, on the Common Stock with respect to
the same dividend period.

                  Upon any dissolution, liquidation or winding up of the
Corporation, whether voluntary or involuntary, the holders of the Preferred
Stock shall be entitled to receive out of the assets of the Corporation, before
any distribution shall be made to the holders of the Common Stock, the amounts
determined to be payable on the Preferred Stock of each series in the event of
voluntary or involuntary liquidation.

                  No holder of Preferred Stock shall be entitled to any
preemptive rights.

                  The Corporation may issue rights and options to purchase
shares of Preferred Stock of the Corporation to Directors, Officers or employees
of the Corporation or any affiliate thereof, and no shareholder approval or
ratification of any such issuance of rights and options shall be required.

                                   Section 3.

                  Cumulative Voting. At all elections of directors of the
Corporation, or at elections held under specified circumstances, each holder of
stock or of any class or classes or of a series or series thereof shall be
entitled to as many votes as shall equal the number of votes which he would be
entitled to cast for the election of directors with respect to his shares of
stock multiplied by the number of directors

                                       3
   4
to be elected by him, and he may cast all of such votes for a single director or
may distribute them among the number to be voted for, or for any two or more of
them as he may see fit.

                                    ARTICLE V

                               BOARD OF DIRECTORS

                  The number of persons to serve on the Board of Directors shall
be fixed by the Bylaws.

                                   ARTICLE VI

                                 INDEMNIFICATION

                                   Section 1.

                  A director of the Corporation shall not be personally liable
to the Corporation or its stockholders for monetary damages for breach of
fiduciary duty as a director, except for liability (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) under Section 174 of the Delaware General
Corporation Law, or (iv) for any transaction from which the director derived any
improper personal benefit. If the Delaware General Corporation Law is amended to
authorize corporate action further eliminating or limiting the personal
liability of directors, then the liability of a director of the Corporation
shall be eliminated or limited to the fullest extent permitted by the Delaware
General Corporation Law, as so amended.

                  Any repeal or modification of the foregoing paragraph by the
stockholder of the Corporation shall not adversely affect any right or
protection of a director of the Corporation existing at the time of such repeal
or modification.

                                   Section 2.

                           a. Right to Indemnification. Each person who was or
is made a party or is threatened to be made a party to or is otherwise involved
in any action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter a "Proceeding"), by reason of the fact that he or she
is or was a director, officer or employee of the Corporation or is or was
serving at the request of the Corporation as a director, officer, employee or
agent of another Corporation or of a partnership, joint venture, trust or other
enterprise, including service with respect to employee benefit plans
(hereinafter an "Indemnitee"), whether the basis of such Proceeding is an
alleged action in an official capacity as a director, officer, employee or agent
or in any other capacity while serving as a director, officer, employee or
agent, shall be indemnified and held harmless by the Corporation to the fullest
extent authorized by the Delaware General Corporation Law, as the same exists or
may hereafter be amended (but, in the case of any such amendment, only to the
extent that such amendment permits the Corporation to provide broader
indemnification rights than such law permitted the Corporation to provide prior
to such amendment), against all expense, liability and loss (including
attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts
paid in settlement) reasonably incurred or suffered by such Indemnitee in
connection therewith and such indemnification shall continue as to an Indemnitee
who has ceased to be a director, officer, employee or agent and shall inure to
the benefit of the Indemnitee's heirs, executors and administrators; provided,
however, that, except as provided in paragraph (b) hereof with respect to
Proceedings to enforce rights to indemnification, the Corporation shall
indemnify any such Indemnitee in

                                       4
   5
connection with a Proceeding (or part thereof) initiated by such Indemnitee only
if such Proceeding (or part thereof) was authorized by the Board of Directors of
the Corporation. The right to indemnification conferred in this Section shall be
a contract right and shall include the right to be paid by the Corporation the
expenses incurred in defending any such Proceeding in advance of its final
disposition (hereinafter an "Advancement of Expenses"); provided, however, that,
if the Delaware General Corporation Law requires, an Advancement of Expenses
incurred by an Indemnitee in his or her capacity as a director or officer (and
not in any other capacity in which service was or is rendered by such
Indemnitee, including without limitation, service to an employee benefit plan)
shall be made only upon delivery to the Corporation of an undertaking, by or on
behalf of such Indemnitee, to repay all amounts so advanced if it shall
ultimately be determined by final judicial decision from which there is no
further right to appeal that such Indemnitee is not entitled to be indemnified
for such expenses under this Section or otherwise (hereinafter and
"Undertaking").

                           b. Right of Indemnitee to Bring Suit. If a claim
under paragraph (a) of this Section is not paid in full by the Corporation
within sixty days after a written claim has been received by the Corporation,
except in the case of a claim for an Advancement of Expenses, in which case the
applicable period shall be twenty days, the Indemnitee may at any time
thereafter bring suit against the Corporation to recover the unpaid amount of
the claim. If successful in whole or in part in any such suit or in a suit
brought by the Corporation to recover an Advancement of Expenses pursuant to the
terms of an Undertaking, the Indemnitee shall be entitled to be paid also the
expense of prosecuting or defending such suit. In (i) any suit brought by the
Indemnitee to enforce a right to indemnification hereunder (but not in a suit
brought by the Indemnitee to enforce a right to an Advancement of Expenses) it
shall be a defense that, and (ii) any suit by the Corporation to recover an
Advancement of Expenses pursuant to the terms of an Undertaking the Corporation
shall be entitled to recover such expenses upon final adjudication that, the
Indemnitee has not met the applicable standard of conduct set forth in the
Delaware General Corporation Law. Neither the failure of the Corporation
(including its Board of Directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
suit that indemnification of the Indemnitee is proper in the circumstances
because the Indemnitee has met the applicable standard of conduct set forth in
the Delaware General Corporation Law, nor an actual determination by the
Corporation (including its Board of Directors, independent legal counsel, or its
stockholders) that the Indemnitee has not met such applicable standard of
conduct, shall create a presumption that the Indemnitee has not met the
applicable standard of conduct or, in the case of such a suit brought by the
Indemnitee, be a defense to such suit. In any suit brought by the Indemnitee to
enforce a right hereunder, or by the Corporation to recover an Advancement of
Expenses pursuant to the terms of an undertaking, the burden of proving that the
Indemnitee is not entitled to be indemnified or to such Advancement of Expenses
under this Section or otherwise shall be on the Corporation.

                           c. Non-Exclusivity of Rights. The rights to
indemnification and to the advancement of expenses conferred in this Section
shall not be exclusive of any other right which any person may have or hereafter
acquire under any statute, this Certificate of Incorporation, Bylaws, agreement,
vote of stockholders or disinterested directors or otherwise.

                           d. Insurance. The Corporation may maintain insurance,
at its expense, to protect itself and any director, officer, employee or agent
of the Corporation or another Corporation, partnership, joint venture, trust or
other enterprise against any expense, liability or loss, whether or not the
Corporation would have the power to indemnify such person against such expense,
liability or loss under the Delaware General Corporation Law.

                                       5
   6
                           e. Indemnification of Agents of the Corporation. The
Corporation may, to the extent authorized from time to time by the Board of
Directors, grant rights to indemnification and to the advancement of expenses,
to any agent of the Corporation to the fullest extent of the provisions of this
Section with respect to the indemnification and advancement of expenses of
directors, officers and employees of the Corporation.


                                   ARTICLE VII

                              ELECTION OF DIRECTORS

                  All elections of Directors will be by ballot vote where a
ballot vote is demanded by any person entitled to vote prior to the time the
voting begins; otherwise, a voice vote will suffice.


                                  ARTICLE VIII

                               AMENDMENT OF BYLAWS

amended or repealed or new bylaws may be adopted by the stockholders only (i)
upon the affirmative vote as to all the stock held by the holders of not less

                  Interested Stockholder has previously paid for shares of such

                  a majority of the Continuing Directors; (ii) there shall have
                  been

                  Continuing Directors; (iii) there shall have been an increase

                  reorganization or any similar reorganization which has the
                  effect of reducing the number of issued and outstanding shares

                  annual rate is approved by a majority of the Continuing
                  Directors; and (iv) such Interested Stockholder shall not have
                  become the Beneficial Owner of any additional Voting Stock
                  except as part of the transaction which results in such
                  Interested Stockholder becoming an Interested Stockholder; and

                                    (e) after such Interested Stockholder has
                  become an Interested Stockholder, such Interested Stockholder
                  shall not have received the benefit, directly or indirectly
                  (except proportionately as a shareholder), of any loans,

                  such Business Combination or otherwise; and

shares of capital stock of the Corporation that pursuant to or in accordance
with this Second restated Certificate of Incorporation are entitled to vote
