faith by the Company and the Holder.

authorized, validly issued, fully paid and nonassessable and free from all
preemptive rights of any stockholder and free of all taxes (other than income
taxes, which may be applicable to Holder, liens and charges with respect to the
issue thereof. The Company covenants that it will reserve and keep available a
sufficient number of shares of its authorized but unissued Stock for such
exercise. The Company will take all such reasonable action as may be necessary

Stock is not then publicly traded, the Market Value shall be determined in good
faith by the Company and the Holder.

GENERAL

         This license and development agreement calls for the research and
development and testing for a proprietary oncogenic fluorescence HPV viral
system utilizing in-vitro hybridization and unique probe(s).

         This system shall be designed to be employed at POC in a desktop
instrument capable of detection of specific HPV related viral probes using
fluorescence and shall be based around the POC analyzer being developed by
Ampersand Medical.

SPECIFICATION REQUIREMENTS

-   Detection time of 1 hour (desired), 2 hours maximum
-   Sensitivity of 99.0%
-   Specificity of 90.0%
-   Detection in solution of no greater than .5 ml.
-   A single fluorescence recorder dye at an excitation (532 or 635nm)
-   SNR > TBD (>10:1)
-   Maximum number of reagents not to exceed 6
-   Maximum temperature 37(degree)C

HPV TEST SPECIFICATIONS

COMPONENTS:

-   Wash solution 1
-   Wash solution 2
-   Hybridization solution
-   Probe cocktail
-   Stringency wash 1
-   Stringency wash 2

Can be combined with antibodies that are applied prior to wash solution 1.
Excludes all antibodies labeled with PerCP (Becton-Dickinson).

Washes 1 and 2 will be performed at room temperature. Hybridization temperature
will be less than 37(degree) C.

Hybridization will take less than 2 hours.

WORKSCOPE

All development work will be performed under the supervision of Dr. Bruce K.
Patterson by a senior level scientist. The majority of work will be performed in
laboratory space rented by INVIRION.

The work will proceed as follows:

1.  Probe reconfiguration using gene sequence analysis software.
2.  Virtual hybridization performed.
3.  Presumptive probe cocktail synthesized.
4.  Individual probes (<200) tested on normal squamous cells for non-specific
    hybridization.
5.  First generation probe cocktail pooled (generated) based on results from 4.
6.  Initial testing on Caski cells with normal squamous cells as controls.
7.  Generate signal to noise data.
8.  Reconfigure probe pool if necessary.
9.  Freeze probe formula.
10. Convert fluorochrome labeling of oligonucleotides based on Ampersand
    instrument specifications.
11. Sign off on final probe configuration, test reagents and processes.
