(a) Any Foreground Intellectual Property developed or created in Unipath's Field
of Interest shall vest in and be owned absolutely by Unipath and any Foreground
Intellectual Property developed or created in HET's Field of Interest shall vest
in and be owned absolutely by HET. Nothing in this agreement shall restrict a

Intellectual Property Rights, the dispute shall be dealt with in accordance with
clause 14.

4.4 Each party agrees to sign all documents and provide any other reasonable

the termination of this agreement so that the party making the request may apply
for, obtain and enforce any of its Foreground Intellectual Property Rights .

4.5 To the extent that either party sub-contracts performance of the Project,
that party shall ensure that any Foreground Intellectual Property Rights created
from the work of its sub-contractors shall be assigned to the party whose
relevant Field of Interest those Foreground Intellectual Property Rights fall
within.

4.6 Each party shall immediately give written notice to the other of any
infringement or threatened infringement of, or any challenge to, the other
party's Background Intellectual Property Rights, Foreground Intellectual
Property Rights or any unauthorised use of the other party's Technology and
Know-How by a third party which comes to its knowledge. The party that owns the
Background Intellectual Property Rights, Foreground Intellectual Property Rights
or Technology and Know-How to which the infringement, threatened infringement or
challenge relates shall decide, in its sole discretion, what steps shall be
taken (if any) to resolve the activity.

4.7 Subject to the remainder of this clause 4, each party (Indemnifying Party)
shall, at its own expense, defend or at its option settle any action brought
against the other party (Indemnified Party) which consists of a claim that the
use of the Indemnifying Party's Technology and Know-How or Background
Intellectual Property Rights for any activity contemplated under this agreement
infringes any Intellectual Property Right belonging to a third party, and the
Indemnifying Party agrees to be responsible for all losses, costs (including
reasonable legal costs), damages, liabilities, claims and expenses suffered or
incurred by the Indemnified Party in connection with any such claim. The
Indemnifying Party's obligations under this clause 4.7 shall be conditional on
the Indemnified Party:

(b) giving the Indemnifying Party express authority to proceed as contemplated
by this clause4.7; and

(c) providing the Indemnifying Party with all such available information and
assistance as it may reasonably require.

4.8 In addition and without prejudice to clause 4.7, in the event that the use
of the Indemnifying Party's Technology and Know-How or Background Intellectual
Property Rights for any activity contemplated under this agreement infringes any
Intellectual Property Right belonging to a third party, the Indemnifying Party
shall have the right, at its sole option and at its own expense, either to
modify its Technology and Know-How or

                                        6
<PAGE>


Background Intellectual Property Rights to be non-infringing or to obtain at its
own expense for the Indemnified Party a licence to continue using the
Indemnifying Party's Technology and Know-How or Background Intellectual Property
Rights, provided that in the event that the parties reasonably agree that it is
not possible either to modify the Indemnifying Party's Technology and Know-How
or Background Intellectual Property Rights to be non-infringing or to obtain for
the Indemnified Party a licence to continue using the Indemnifying Party's
Technology and Know-How or Background Intellectual Property Rights then the
Indemnified Party may terminate this agreement immediately on written notice.
Termination under this clause 4.8 shall be without prejudice to the rights of
either party accrued at the date of termination.

THE PROJECT

o Title

Feasibility, development and introduction to market of a low-cost, minimally
invasive system to measure plasma or blood coagulation using the patented
technology of Unipath and the patented measurement techniques of HET.

o Objectives of Project

HET Obligations:

HET shall use its reasonable efforts to achieve the objectives of the three
stages of the projects within the time frame set out in Schedule 3. The three
stages are as follows:

Stage 1: Proof of principle and optimise measurement methodology:

Outcome: Definition of the measurement methodology (or combination of
methodologies) Demonstration of the test principle using laboratory equipment
and prototype test devices Assessment of the performance characteristics of the
test Blood volume requirement (Target <= 1ul) Accuracy: Correlation of the
measurement method to a lab result using clinical reference sample (Target
Correlation => 0.95) Precision: Reproducibility of a sample tested at low, mid
and high INR (Target Precision <= 5% CV at all levels)

Stage 2: Development of the system design and configuration

Outcome: Development of the system performance, Definition of the instrument
design Development of the system configuration to achieve product requirement
specifications: Definition of the instrument design to meet product requirement
specifications

Stage 3: Optimised system configuration for production release and transfer of
         the technology to Unipath Meter design finalised

Meter bill of materials defined Meter design specifications defined 1st run
meter samples built Meter reliability testing completed Meter test fixtures
requirements defined Meter hardware and software validation plans defined Final
system tested to meet product requirements specifications

UNIPATH Obligations:
During each stage of the project and within the time frames set out in schedule
3, Unipath shall ensure the timely supply of materials and technical support as
may be reasonably requested by HET from time to time to support the projects.
