collected Funds received from Samsung and shall be paid over the time period
during which payments from Samsung are received by either of the Companies. Each
Company agrees to make payments to Consultant within seven (7) business days of
receipt of cleared funds from Samsung in the Company's account. If there is a
failure by either Company to make any payment to Consultant within the time

shall not be entitled to any of the rights and privileges established for the
employees of the Companies (if any), including but not limited to the following
retirement benefits, medical insurance coverage, severance pay benefits, paid
vacation and sick pay, overtime pay or any of the foregoing items. Consultant

compensation paid to Consultant pursuant to this Agreement any sums customarily
paid or withheld for or on behalf of employees for income tax, unemployment
insurance, social security, worker's compensation or any other withholding tax,
insurance or payment pursuant to any law of governmental requirement, and all
such payments as may be required by law are the sole responsibility of
Consultant. Consultant agrees to hold the Companies harmless against, and
indemnify the Companies for any of such payments of liabilities for which the
Companies, or either of them, may become liable with respect to such matters.
This Agreement shall not be construed as a partnership agreement.

         The Companies shall have no responsibility for any of Consultant's
debts, liabilities or other obligations, or for the intentional, reckless,
negligent or unlawful acts or omissions of Consultant or Consultant's employees
or agents.

         6.       Confidentiality. Consultant shall not for any reason or at any
time, whether during or after the term of this Agreement, disclose to any person

disclosure to employees or agents of Samsung and such persons have entered into
a confidentiality agreement in form and substance satisfactory to the Companies)
any secret or confidential information obtained by Consultant in the course of,
or as a result of, performance of this Agreement, which secret or confidential
information relates to either Company or any subsidiary corporation of either
Company, unless so authorized by the President or Executive Vice President of
the Company to which such confidential information relates. Any information that

of the provisions of this paragraph, the affected Company shall be entitled to
an injunction restraining Consultant from disclosing, in whole or in part, any
such secret or confidential information; provided, however, that nothing herein
shall be construed as prohibiting either Company from pursuing any other
remedies available for any such breach or threatened breach, including the
recovery of damages from Consultant.

         7.       Rights to Materials. All records, files, memoranda, reports,
price lists, customer lists, plans, drawing, sketches, documents and the like

any of their subsidiaries that Consultant shall use or prepare or come into

Agreement shall remain the sole property of the Company to whose business such
information relates. Upon termination of this Agreement or upon the prior demand
of either Company, Consultant shall immediately return all such materials to the
Company to which such materials belong.

         8.       Rights to Inventions and Technology. Any and all methods,

either in law or in equity, to enjoin Consultant from violating any of the terms
of this Agreement, to enforce the specific performance by Consultant of any of

nothing herein contained shall be construed to prevent such remedy or
combination of remedies as the Companies may, in their discretion, choose to
invoke. The failure of either Company to promptly institute legal action upon
any breach of this Agreement shall not constitute a waiver of that or any other
breach hereof.
