Ladies and Gentlemen:

     At your request we have examined the section entitled "Cayman Islands Tax
Consequences" in the Registration Statement on Form S-4 to be filed with the
Securities and Exchange Commission in connection with the Company. We are of the
opinion that this is a fair and accurate summary of the Cayman Islands tax
implications of the merger of Apco Delaware, Inc. with and into Globex Energy,
Inc.

     We consent to the use of this opinion as an exhibit to the Registration
Statement, and to the use of our name under the caption "Cayman Islands Tax
Consequences". Except as set forth above, we express no other opinion. This
opinion is expressed as of the date hereof and we disclaim any undertaking to
advise you of subsequent changes relating to matters considered herein or of any
subsequent changes in applicable law.

Yours faithfully,
