Amendments
                to Articles of Incorporation or Bylaws; Change of Fiscal
                Year
On
      December 11 2007, the registrant's board of directors approved pursuant to an
      unanimous written consent effective December 1, 2007 an amendment and
      restatement of Article IX of the registrant's by-laws to allow for
      uncertificated shares of the registrant in order for such shares to be eligible
      for participation in the Direct Registration System of the Depository Trust
      Company by January 1, 2007.  This system will allow for the electronic
      issuance and transfer of uncertificated shares of NL common stock.  In
      addition, the amendment added certain additional language
      regarding:
·
requirements
                for stock certificates;
·
lost
                of stolen stock certificates;
·
the
                registrant's right to recognize the exclusive right of a person registered
                on its books as the owner of shares;
                and
·
restrictions
                on transfers of shares
Pursuant
      to the amendment and restatement, Article IX of the registrant's by-laws reads
      in its entirety as follows:
ARTICLE IX
STOCK
      CERTIFICATES
9.1
Form
.  The
      shares of stock of the Corporation shall be represented by certificates, or
      shall be uncertificated shares.  Every holder of uncertificated shares
      of the Corporation shall be entitled upon request to have a stock certificate
      issued to such holder signed by the chairman of the board, the president or
      any
      vice-president, and may be countersigned by the treasurer or an assistant
      treasurer, or the secretary or an assistant secretary, certifying to the number
      of shares owned by such shareholder.  Any and all signatures upon a
      certificate may be a facsimile.  In case any officer, transfer agent
      or registrar who has signed or whose facsimile signature has been placed upon
      such certificate, shall have ceased to be such officer, transfer agent or
      registrar before such certificate is issued, it may be issued by the Corporation
      with the same effect as if he or she were such officer, transfer agent or
      registrar at the date of issue.  All certificates for shares shall be
      consecutively numbered or otherwise identified.  The name of the
      person to whom either certificated or uncertificated shares are issued, with
      the
      number of shares and date of issue, shall be entered on the books of the
      Corporation.  Notwithstanding any other provision in these By-Laws,
      the Corporation may adopt a system of issuance, recordation and transfer of
      its
      shares by electronic or other means not involving any issuance of certificates,
      including provisions for notice to purchasers in substitution for any required
      statements or certificates, and as may be required by applicable law, which
      system has been approved by the U.S. Securities and Exchange
      Commission.  Any system so adopted shall not become effective as to
      issued and outstanding certificated securities until the certificates therefor
      have been surrendered to the Corporation.
9.2
Transfers
.  Transfers
      of stock shall be made only upon the transfer books of the Corporation or
      respective transfer agents designated to transfer the several classes of stock
      and, in the case of shares represented by a certificate or certificates, upon
      the surrender of a properly endorsed certificate or certificates for a like
      number of shares.
9.3
Lost
      or Destroyed Certificates
.  The Corporation may issue a new stock
      certificate in place of any certificate theretofore issued by it, alleged to
      have been lost, stolen or destroyed, and the Corporation shall, except as
      otherwise determined by the board of directors, the chairman of the board,
      the
      president, the chief executive officer any vice-president or other authorized
      officer, require the owner of the lost, stolen or destroyed certificate, or
      his
      or her legal representative, to give the Corporation a bond sufficient to
      indemnify it against any claim that may be made against it on account of the
      alleged loss, theft or destruction of any such certificate or the issuance
      of
      such new certificate.
9.4
Registered
      Stockholders
.  The Corporation shall be entitled to recognize the
      exclusive right of a person registered on its books as the owner of shares
      to
      receive dividends, and to vote as such owner, and to hold liable for calls
      and
      assessments a person registered on its books as the owner of shares, and shall
      not be bound to recognize any equitable or other claim to or interest in such
      shares on the part of another person, whether or not the Corporation shall
      have
      express or other notice thereof, except as otherwise provided by the laws of
      the
      State of New Jersey.
9.5
Restrictions
      on Transfers of Shares
.  Notice of any restriction on the
      transfer of shares of the Corporation's stock shall be placed on each
      certificate of stock issued, or in the case of uncertificated shares, contained
      in the notice sent to the registered holder of such shares, in addition to
      such
      other requirements of the laws of the State of New Jersey for such certificate
      or notice.
Prior
      to
      such amendment, Article IX of the registrant's by-laws read in its entirety as
      follows:
ARTICLE
      IX
TRANSFER
      OF STOCK
Shares
      of
      stock of the Corporation shall be transferred only on the books of the
      Corporation by the holder thereof, in person or by his attorney duly authorized
      thereto in writing, upon the surrender of the certificate
      therefor.  Whenever any transfer shall be made for collateral security
      and not absolutely, the same shall be so expressed in the entry of said
      transfer.
In
      the
      case of loss or destruction of a certificate of shares of stock, another may
      be
      issued in its place, upon proof of such loss and the giving of a satisfactory
      bond of indemnity.
