    WHEREAS,
      the
      Board of Directors of the Alabama Company and the Board of Directors of the
      Texas Company deem it to be for the benefit and advantage of each of the
      companies and their respective stockholders that the companies merge under
      and
      pursuant to the provisions of Section 10-2A-146 of the Alabama Business
      Corporation Act and Section 5.07 of the Texas Business Corporation Act, and
      the

      purpose, among others, of considering approval of the Agreement.

    Except
      as
      herein specifically set forth, the corporate existence of the Texas Company,
      with all its purposes, powers and objects, shall continue in effect and

      the
      purposes, powers, and objects of the Alabama Company, shall be merged into

      merger shall become effective only if the Agreement is adopted by the
      stockholders of the Constituent Companies as provided in Article X hereof.
      Upon
      such adoption, that fact shall be certified upon the Agreement by the Secretary
      or Assistant Secretary of each of the Constituent Companies, under the seal

      Corporation Act,

      Merger shall be filed with the Secretary of State of Alabama. The merger shall

      property, real and personal, including subscriptions to shares,

    causes
      of
      action and every other asset of each of the Constituent Companies, shall vest
      in
      the Surviving Company without further act or deed; and the Surviving Company
      shall be liable for all of the liabilities, obligations and penalties of each
      of

      effective date of the merger, shall be cancelled and retired. 

     

    ARTICLE

    The
      officers and directors of the Alabama Company immediately prior to the effective

      Company, until their successors shall have been elected and shall qualify or
      as
      otherwise provided in the Bylaws of the Surviving Company. 

     

    If,
      on or
      after the effective date of the merger, a vacancy shall exist in the Board

    ARTICLE
      IX

     

    All
      corporate acts, plans, policies, approvals and authorizations of the Alabama
      Company, its stockholders, Board of Directors, committees elected or appointed
      by the Board of Directors, officers and agents, which were valid and effective
      immediately prior to the effective date of the merger, shall be taken for all
      purposes as the acts, plans, policies, approvals and authorizations of the
      Surviving Company and shall be as effective and binding thereon as they were
      on
      the Alabama Company. Without limiting the foregoing, all stock option, stock
      purchase and profit sharing plans of the Alabama Company, all as amended and
      in
      effect immediately prior to the merger becoming effective, and any and all
      outstanding options and rights thereunder, shall be continued by the Surviving
      Company, which shall be substituted for the Alabama Company. Such merger shall
      not, in itself, effect any other change in such plans, options or rights. The
      employees of the Alabama Company shall become the employees of the Surviving
      Company and continue to be entitled to the same rights and benefits they enjoyed
      as employees of the Alabama Company. It is intended that the transaction
      described herein qualifies as a reorganization within the definition of Clause
      (F) of Section 368(a)(l) of the Internal Revenue Code of 1986, as amended.
