Item 5.03.    Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year

On December 6, 2007, the Board of Directors of OI Corporation (the "Company") amended Section 1 of Article VI of the Company's Bylaws to expressly provide for the issuance of un-certificated shares of the Company's stock in order to comply with a NASDAQ rule change requiring listed securities to be eligible to participate in the Direct Registration System by January 1, 2008. The Direct Registration System allows investors to have securities registered in their names without the issuance of physical certificates and allows investors to electronically transfer securities to broker-dealers in order to effect transactions without the risks and delays associated with transferring physical certificates. The System is currently administered by the Depository Trust Company.

The amendment to the Bylaws is filed as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference.
