Dear Ken:

This letter confirms the terms and conditions of a Contract Manufacturing
Arrangement between Unotech Diagnostics, Inc. of San Leandro, California and
Matritech, Inc. of Newton, Massachusetts. Would you please sign both copies and
return one original to me.

Purpose:

commercial commitments included in this contract.

Unotech is a manufacturer of various point-of-care testing devices and is able
to manufacture the NMP22 POC Test in the quantities projected by Matritech and
is willing to make the commercial commitments included in this contract.

Product:

The Matritech NMP22 POC Test (the "Product") is a lateral flow
immunochromatographic assay that measures the nuclear matrix protein NuMA
(nuclear mitotic apparatus protein) in freshly voided, untreated urine. The
device employs two monoclonal antibodies that recognize different epitopes on
the NuMA molecule.

Minimum Purchases and Pricing:

Matritech will pay the following prices:
For orders of [**] to [**] units, $[**] per unit
For orders of [**] to [**] units, $[**] per unit
For orders of [**] or more units, $[**] per unit.
Matritech will provide the necessary reagents to test intermediate and final
product and will supply the antibodies incorporated in the product based on
Unotech's forecasted requirements.. These prices are F.O.B. Unotech's dock.
