                             NOTES AND INSTRUCTIONS


       
NOTE 1:   State the true exact corporate name as it appears on the records of the office of the Secretary of
          State, BEFORE any amendments herein reported.

NOTE 2:   Incorporators are permitted to adopt amendments ONLY before any shares have been issued and before
          any directors have been names or elected. ((S) 10.10)

NOTE 3:   Directors may adopt amendments without shareholder approval in only six instances, as follows:
          (a)  to remove the names and addresses of directors named in the articles of incorporation;
          (b)  to remove the name and address of the initial registered agency and registered office, provided a
               statement pursuant to (S) 5.10 is also filed;
          (c)  to split the issued whole shares and unissued authorized shares by multiplying them by a whole
               number, so long as no class or series is adversely affected thereby;
          (d)  to change the corporate name by substituting the word "corporation", "incorporated", "company",
               "limited", or the abbreviation "corp.", "inc.", "co", or "ltd" for a similar word or abbreviation
               in the name, or by adding a geographical attribution to the name;
          (e)  to reduce the authorized shares of any class pursuant to a cancellation statement filed in
               accordance with (S) 9.05.
          (f)  to restate the articles of incorporation as currently amended. ((S) 10.15)

NOTE 4:   All amendments not adopted under (S) 10.10 or (S) 10.15 require (1) that the board of directors adopt
          a resolution setting forth the proposed amendment and (2) that the shareholders approve the
          amendment.

          Shareholder approval may be (1) by vote at a shareholders' meeting (either annual or special) or (2)
          by consent, in writing, without a meeting.

          To be adopted, the amendment must receive the affirmative vote or consent of the holders of at least
          2/3 of the outstanding shares entitled to vote on the amendment (but if class voting applies, then
          also at least a 2/3 vote within each class is required).

          The articles of incorporation may supersede the 2/3 vote requirement by specifying any smaller or
          larger vote requirement not less than a majority of the outstanding shares entitled to vote and not
          less than a majority within each class when class voting applies. ((S) 10.20)

NOTE 5:   When shareholder approval is by written consent, all shareholders must be given notice of the proposed
          amendment at least 5 days before the consent is signed. If the amendment is adopted, shareholders who
          have not signed the consent must be promptly notified of the passage of the amendment. ((S)(S) 7.10 &
          10.20)
