--------------------------------------------------------------------------------

The contract ends at the end of the month in which Dr. Sappok reaches the age of
65. Any renewal of the contract after that point in time shall be by mutual
agreement between Dr. Sappok and the Employer’s shareholders.

In case of termination by Dr. Sappok, the Company may forego, in whole or in
part, any additional work by Dr. Sappok with the continued payment of his fixed
remuneration (fixed salary and guaranteed management bonus) until the end of the
termination period. If the company foregoes any of Dr. Sappok’s services, his
entire remuneration from new employment shall be deducted from the remuneration
thus far.

In the event that Dr. Sappok is temporarily prevented from fulfilling his
responsibilities as Managing director due to illness, or for other reasons for
which he cannot justify, Dr. Sappok shall receive the fixed remuneration (fixed
salary and guaranteed management bonus) for a period of 6 months, however, not
for longer than the contract period. After the 6 months, the supervisory board
shall make a decision regarding continued payment of the remuneration, if
necessary.

In case of death, his widow, Mrs. Elisabeth Sappok, nee Graf, shall receive the
fixed remuneration (fixed salary and guaranteed managed bonus) for 3 months,

--------------------------------------------------------------------------------

Dr. Sappok is obligated to maintain as company property any business documents
and his own records, if they pertain to company activities, and maintain
confidentiality, and must turn over these documents to the company upon request,
however, at the latest at the end of the employment contract, unless this is
unreasonable in an isolated case under special circumstances.

Records pertaining to results, which are based on his creative work and which
are pertinent to the business purpose of the Employer, shall be made available
to the company at the end of the employment contract. Dr. Sappok may keep these,
if it does not run counter to any special company interests.

The obligation of secrecy does not end at the end of the employment contract. As
long as Dr. Sappok does not receive any pension benefits from the company and is
not obligated by a prohibition of competition, the obligation of secrecy does
not apply after the end of the employment contract, as long as Dr. Sappok
demonstrates that the limitation of his professional activities is unreasonable
in relation to the company’s interests concerning secrecy.

§ 8 Employment on the side

Any employment on the side requires express prior written consent from the
shareholders. Participation in limited companies as well as the participation in
company supervisory bodies is considered as employment on the side.

Law concerning employee inventions [“Gesetz ueber Arbeitnehmererfindungen”] as
well as the guidelines pertaining thereto, with the exception of § 22 of the law

§ 11 Contract amendments

Additions or amendments to this contract must be made in writing and are only
legally effective, if signed by both parties to the contract. If one contract
clause becomes legally ineffective, the validity of the other provisions shall
not be affected. In this case, the parties to the contract are obligated to
determine a provision, which economically most closely reflects the purpose of
the ineffective provision. The same applies for any gaps in the contract.

The conclusion of the contract renders any previous contracts and agreements
invalid.

§ 12 Other liabilities

The employer1 shall assume the directly enforceable guarantee for any
liabilities under this contract.

This contract has been prepared in duplicate. Each party to the contract
receives one copy.

    1 Translator’s note: Here the word “Auftraggeber” is used instead of
“Arbeitgeber,” used up to this point. Auftraggeber is usually understood to mean
“client,” but can also be translated as employer. “Arbeitgeber” on the other
hand always means “Employer.”
