         Accordingly, the Company amended its Articles of Incorporation to
reflect the name change and 1-for-10 reverse stock split. Because our board of
directors believes that it is advisable to restate the Articles of Incorporation
reflecting all previous amendments into one document for administrative ease
when filing with the Texas Secretary of State, Securities and Exchange
Commission and other third parties, we have amended and restated our Articles of
Incorporation which was filed with the Texas Secretary of State on June 16,
2006. A copy of our amended and restated Articles of Incorporation is attached
as Exhibit 3.1

         In connection with the name change, the Company was assigned a new
ticker symbol "OPXA", and the Company's common stock will continue to be traded
on the OTC Bulletin Board.

         On or about June 19, 2006, the Company's transfer agent, Continental
Stock Transfer & Trust Co. will send a letter of transmittal to the Company's
shareholders instructing them how to exchange their old stock certificates for
new stock certificates.

         The Company's press release is attached to this Current Report on Form
8-K as Exhibit 99.1.
