         5. Confidential Information: Advisor and the Company acknowledge that
the Company's business is highly competitive and that the Company may, from time
to time, provide Advisor with access to confidential information. Advisor agrees
that he will not make any unauthorized disclosure of confidential business
information obtained from the Company ("Confidential Information"), or make any
unauthorized use thereof. However, Advisor shall be permitted to disclose
Confidential Information as is required by law, including deposition or trial
testimony pursuant to subpoena, provided that if he is requested or required (by
oral question, interrogatories, request for information or documents, subpoena,
civil investigative demand or similar process) to disclose any Confidential
Information, if reasonably possible under the circumstances as determined in
good faith, he will promptly notify the other party of such request or
requirement so that the other party may seek an appropriate protective order or
waive compliance with the provisions of this Agreement.

         In the absence of a protective order or the receipt of a waiver
hereunder, or in the good faith determination of Advisor that time is of the
essence, Advisor shall obtain legal counsel, and if Advisor and/or his counsel
in good faith believe that Advisor is compelled to disclose the Confidential
Information or be exposed to liability for contempt or suffer other censure or
penalty, Advisor may disclose only such Confidential Information to the party
compelling disclosure as is required by law, as determined by Advisor on advice
of counsel. Advisor further agrees that he will cooperate with the Company in
its efforts to obtain a protective order or other reliable assurance that
confidential treatment will be accorded the Confidential Information. All
reasonable legal fees, costs and expenses incurred by Mr. Gibbs in obtaining
legal representation pursuant to his obligations under this paragraph shall be
paid by the Company.

apply during the term of this Agreement and shall survive for one year following
the termination of this Agreement.

         6. Capacity and Benefits: At all times while serving under this
Agreement, Advisor shall be an independent contractor and not a common-law

programs for its employees. Further, Advisor will in no way be considered to be
an agent, employee, or servant of the Company. Advisor shall have no authority
to bind the Company without receiving specific written authority to do so. It is

same shall not be construed as creating, any partnership, partnership relation,
joint venture, agency, or employment relationship.
