This Contract deals with the manufacturing as well as the distribution of

Provision 3: Production Cost

The direct product cost (including salary costs) relative to the manufacture of
the cameras will be charged to D.M.D.S.

The exact amount of these costs will be transmitted by DDM to D.M.D.S., which is
engaged in the payment of these costs, at the presentation of the bill when the
cameras are delivered and not any supplementary cost will be charged to D.M.D.S.

The parts necessary to the manufacture of these cameras will be administered
and purchased by DDM and billed to D.M.D.S. "au franc le franc", with payment
terms identical to those which DDM gets from its vendors.

Provision 4: Amortization

Not included in the production costs are all the indirect costs such as
investment connected to the production plant (machinery). This stays at the
charge of DDM.

The shipping cost of the parts necessary to the manufacture will be at the
charge of DDM.

Provision 5: Transfer of Production

It is agreed between the parties that there is a possibility that DMDS will be
in charge of the production of the wireless cameras for the North American
market. If D.M.D.S. chooses this option, DDM promises to collaborate with
D.M.D.S. (meaning to provide the documentation, the manufacturing instructions,
the existing information relating to the production of the wireless cameras),
so that D.M.D.S. could continue the production of these cameras.

For this doing, D.M.D.S. must inform, by all means agree by the parties, the
company DDM, at least three months in advance.

However, the royalties will continue to be paid to DDM by D.M.D.S.

Provision 6: Nullity

The nullity of one clause (or provision) will not be of nature to annul the
entire contract. In such hypothesis, the parties are engaged to negotiate in
good faith for the conclusion of a new clause replacing the void clause.

relating to the execution or to the interpretation of the present agreement.
