           equal amount per share of Class A Common Stock and Class B Common

           also be split, subdivided, combined or reclassified so that the
           number of shares of Class A Common Stock and Class B Common Stock
           outstanding immediately following such split, subdivision,
           combination or reclassification shall bear the same relationship
           to each other as did the number of shares of Class A Common Stock
           and Class B Common Stock outstanding immediately prior to such
           split, subdivision, combination or reclassification.

           (6)  Liquidation, Dissolution, etc.  In the event of any

           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 of the
           Corporation that may at the time be outstanding, in proportion to
           the number of shares held by them, respectively, without regard
           to class.

           (7) Merger, etc.  In the event of a merger or consolidation of
           the Corporation with or into another entity (whether or not the
           Corporation is the surviving entity), the holders of each share
           of Class A Common Stock and Class B Common Stock shall be
           entitled to receive the same per share consideration without
           regard to class.

           (8)  No Preemptive or Subscription Rights.  No holder of shares
           of Class A Common Stock or Class B Common Stock shall be entitled

           requirements of applicable law, the Corporation shall have the
           power to issue and sell all or any part of any shares of any
           class of stock herein or hereafter authorized to such persons,
           and for such consideration, as the Board of Directors shall from
           time to time, in its discretion, determine, whether or not
           greater consideration could be received upon the issue or sale of
           the same number of shares of another class, and as otherwise
           permitted by law.  Subject to the requirements of applicable law,
           the Corporation shall have the power to purchase any shares of
           any class of stock herein or hereafter authorized from such
           persons, and for such consideration, as the Board of Directors
           shall from time to time, in its discretion, determine, whether or
           not less consideration could be paid upon the purchase of the
           same number of shares of another class, and as otherwise
           permitted by law.

           (10)  Conversion.  At any time and from time to time each holder
           of Class A Common Stock shall be entitled to convert any or all
           of such holder's shares into the same number of shares of Class B
           Common Stock, and each holder of Class B Common Stock shall be
           entitled to convert any or all of such holder's shares into the

           Affiliates to, convert any shares of Class B Common Stock into

           conversion, such person would own or control or have owned or
           controlled shares of Class A Common Stock, including all shares
           of Class A Common Stock held by such person while such person was
           subject to Regulation Y, representing 5% or more of the
           outstanding Class A Common Stock; provided, further, that any
           person subject to Regulation Y shall, and any such person shall
           permit any of its Regulation Y Affiliates to, transfer Class B

           transferred to such investor has been fully converted by such
           investor, (c) to any person that already controls the Corporation
           prior to such transfer, (d) in a transaction that complies with
           Rule 144 (or any successor thereto) of the Securities Act of
           1933, as amended, or (e) in any other transaction approved in
           advance by the Federal Reserve System. "Regulation Y Affiliate"

      (c)  Preferred Stock.  The Board of Directors is hereby expressly
      authorized to provide for the issuance of all or any shares of the
      Preferred Stock in one or more classes or series, and to fix for each

      qualifications, limitations or restrictions thereof, as shall be
      stated and expressed in the resolution or resolutions adopted by the
      Board of Directors providing for the issuance of such class or series,
      including, without limitation, the authority to provide that any such
      class or series may be (i) subject to redemption at such time or times
      and at such price or prices; (ii) entitled to receive dividends (which
      may be cumulative or noncumulative) at such rates, on such conditions,
      and at such times, and payable in preference to, or in such relation
      to, the dividends payable on any other class or classes or any other
      series; (iii) entitled to such rights upon the dissolution of, or upon
      any distribution of the assets of, the Corporation; or (iv)

      class or classes of stock, of the Corporation at such price or prices
      or at such rates of exchange and with such adjustments; all as may be
      stated in such resolution or resolutions.

 FIFTH:  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:

      (a)  The business and affairs of the Corporation shall be managed by
      or under the direction of the Board of Directors.

      (b)  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 so provide.

      (c)  A director shall hold office until the annual meeting for the
      year in which his or her term expires and until his or her successor
      shall be elected and shall qualify, subject, however, to prior death,
      resignation, retirement, disqualification or removal from office.

      (d)  Subject to the terms of any one or more classes or series of
      Preferred Stock, any vacancy on the Board of Directors that results
      from an increase in the number of directors may be filled by a
      majority of the Board of Directors then in office, provided that a
      quorum is present, and any other vacancy occurring on the Board of
      Directors may be filled by a majority of the Board of Directors then
      in office, even if less than a quorum, or by a sole remaining
      director.  Any director elected to fill a vacancy not resulting from
      an increase in the number of directors shall have the same remaining
      term as that of his predecessor.  Subject to the rights, if any, of
      the holders of shares of Preferred Stock then outstanding, 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 at least a majority of the voting power of the
      Corporation's then outstanding capital stock entitled to vote
      generally in the election of directors.  Notwithstanding the
      foregoing, whenever the holders of any one or more classes or series
      of Preferred Stock issued by the Corporation shall have the right,
      voting separately by class or series, to elect directors at an annual
      or special meeting of stockholders, the election, term of office,
      filling of vacancies and other features of such directorships shall be
      governed by the terms of this Certificate of Incorporation applicable
      thereto, and such directors so elected shall not be divided into
      classes pursuant to this Article FIFTH unless expressly provided by
      such terms.

      (e)  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 Certificate of Incorporation, and
      any By-Laws adopted by the stockholders; 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:  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 to the extent such exemption from liability or limitation
 thereof is not permitted under the GCL as the same exists or may hereafter
 be amended.  If the GCL is amended hereafter to authorize the further
 elimination or limitation of the liability of directors, then the liability
 of a director of the Corporation shall be eliminated or limited to the
 fullest extent authorized by the GCL, as so amended. Any repeal or
 modification of this Article SIXTH by the stockholders of the Corporation
 shall not adversely affect any right or protection of a director of the
 Corporation existing at the time of such repeal or modification with
 respect to acts or omissions occurring prior to such repeal or
 modification.

 SEVENTH:  The Corporation shall indemnify its directors and officers to the
 fullest extent authorized or permitted by law, as now or hereafter in
 effect, and such right to indemnification shall continue as to a person who
 has ceased to be a director or officer of the Corporation and shall inure
 to the benefit of his or her heirs, executors and personal and legal
 representatives; provided, however, that, except for proceedings to enforce
 rights to indemnification, the Corporation shall not be obligated to
 indemnify any director or officer (or his or her heirs, executors or
 personal or legal representatives) in connection with a proceeding (or part
 thereof) initiated by such person unless such proceeding (or part thereof)
 was authorized or consented to by the Board of Directors.  The right to
 indemnification conferred by this Article SEVENTH shall include the right
 to be paid by the Corporation the expenses incurred in defending or
 otherwise participating in any proceeding in advance of its final
 disposition.

      The Corporation may, to the extent authorized from time to time by the
 Board of Directors, provide rights to indemnification and to the
 advancement of expenses to employees and agents of the Corporation similar
 to those conferred in this Article SEVENTH to directors and officers of the
 Corporation.

      The rights to indemnification and to the advancement of expenses
 conferred in this Article SEVENTH shall not be exclusive of any other right
 which any person may have or hereafter acquire under this Certificate of
 Incorporation, the By-Laws of the Corporation, any statute, agreement, vote
 of stockholders or disinterested directors or otherwise.

      Any repeal or modification of this Article SEVENTH by the stockholders
 of the Corporation shall not adversely affect any rights to indemnification
 and to the advancement of expenses of a director or officer of the
 Corporation existing at the time of such repeal or modification with
 respect to any acts or omissions occurring prior to such repeal or
 modification.

 EIGHTH:  Meetings of 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 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.

 NINTH:  Any action required or permitted to be taken by the stockholders of
 the Corporation must be effected at a duly called Annual or Special Meeting
 of Stockholders of the Corporation and may not be effected by any consent
 in writing by such stockholders unless all of the stockholders entitled to
 vote thereon consent thereto in writing.

 TENTH:  In furtherance and not in limitation of the powers conferred upon
 it by the laws of the State of Delaware, the Board of Directors shall have
 the power to adopt, amend, alter or repeal the Corporation's By-Laws.  The
 affirmative vote of at least a majority of the entire Board of Directors
 shall be required to adopt, amend, alter or repeal the Corporation's By-
 Laws.  The Corporation's By-Laws also may be adopted, amended, altered or
 repealed by the affirmative vote of the holders of at least a majority of
 the voting power of the shares entitled to vote at an election of
 directors.

 ELEVENTH:  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 herein
 conferred upon stockholders are granted subject to such reservation.


           IN WITNESS WHEREOF, the Corporation has caused this Amended and
 Restated Certificate of Incorporation to be executed on its behalf this 6th
 day of January, 2000.
