Jim Stobie

This letter is to advise that Kambi Enterprises, Inc. worked with me in supplying me MWD equipment in order to launch Stealth Directional Services as a part of Transco Oilfield. We were successful in obtaining work in Papua New Guinea, and had a very successful drilling campaign utilizing their equipment.

From the start through completion of the project, Ivan Katic and his entire staff were very thorough, flexible and professional in all the dealings we had. They also trained my personnel in regards to the make-up, breakdown and rebuild of all of the directional tools including thorough instruction of the electronics and readout equipment.

I look forward to our continuing working relationship with Ivan and Kambi Enterprises, Inc. in regards to any upcoming projects that they may be involved in.
