The undersigned, on behalf of the above addressee, agrees to the terms of this letter agreement:

Exhibit A

Informed Consent Form

INFORMED CONSENT FORM

Minnetronix is conducting a study on the industrial design of spinal cord stimulation systems. Through this study Minnetronix hopes to learn more about how people are using and interacting with their systems and, in particular, the programmer and battery recharger. The information obtained by Minnetronix in the study will be used to design and develop more user-friendly spinal cord stimulation systems. You were selected as a possible participant in this study because your physician has notified us that you have an implanted spinal cord stimulation system and you have, at least initially, expressed a willingness to participate in this study.

If you decide to participate in this study, you will be asked to meet with a Minnetronix representative in a hotel conference room in the Denver area for a two-hour videotaped interview. Additionally, several months after the interview, Minnetronix may contact you to request a second, brief follow-up interview. You are not obligated to participate in the follow-up interview and may discontinue participation in this study at any time.

Only Minnetronix and its two sponsors will have access to the study data and information. By signing this informed consent form you agree that Minnetronix, any successor to Minnetronix, and its sponsors may use your personal health information for purposes of the study. Neither Minnetronix nor its sponsors will sell or otherwise disclose to any other third party any personal information which may be obtained in the study. All reasonable efforts will be used by Minnetronix and its sponsors to protect the confidentiality of your identifiable information. Further, while Minnetronix will videotape your interview, your face will not be shown and only your first name will be used.

The study does not involve any medical procedures. There should be no medical risks associated with participating in the study. You will not get any direct clinical benefit from taking part in this study. Hopefully, the information gained from this study will help in the treatment of future patients.

In exchange for your participation in this study, Minnetronix will pay you a fee of $50 per hour. This fee will be paid for interview time only. You will not be paid for travel time or travel expenses. This fee will be paid by check, which will be mailed to you at the address you included below shortly after the completion of the interview.

If you have any questions, please contact Anne Mickelson at (     )                 who will be happy to answer them.

You will be offered a copy of this form to keep.
