                 INFORMATION REQUIRED IN REGISTRATION STATEMENT

     This Amendment No. 1 to our Form 8-A filed with the Securities and Exchange
Commission on July 20, 2006, amends the name of the exchange on which our common
stock is registered. No other changes are made to the Form 8-A.

Item 1.  Description of Registrant's Securities to be Registered.
         -------------------------------------------------------

     The class of securities to be registered hereby is the common stock, $0.001
par value per share (the "Common Stock'), of Houston American Energy Corp., a
Delaware corporation (the "Company").

     A description of the Common Stock is contained under the caption
"Description of Securities" in the Prospectus included in the Registration
Statement on Form SB-2 of the Company, Registration Statement File No.
333-134756, filed with the Securities and Exchange Commission on June 6, 2006
and declared effective on June 16, 2006. Such description is incorporated herein
by reference.

Item 2.  Exhibits.
         --------

     Under the Instructions as to Exhibits with respect to Form 8-A, no exhibits
are required to be filed because no securities of the Company other than its
Common Stock are registered on an exchange and the securities registered hereby
are not being registered pursuant to Section 12(g) of the Securities Exchange
Act of 1934, as amended.

                                    SIGNATURE

     Pursuant to the requirements of Section 12 of the Securities Exchange Act
of 1934, the registrant has duly caused this registration statement to be signed
on its behalf by the undersigned, thereto duly authorized.
