CONFIDENTIAL PROPOSAL

CLINICAL STUDY SERVICES: MIRA-1 STUDY FOR TREATMENT OF AMD

FOR VASCULAR SCIENCES

Revised July 21, 2003

<PAGE>

BACKGROUND

Vascular Sciences and Promedica International have worked together since early
1999 on the company's clinical study of the safety and effectiveness of
Rheopheresis using membrane differential filtration for treatment of age related
macular degeneration. As the company's CRO, Promedica has provided study and
data management services for this trial. Funding difficulties have necessitated
project stops/ slowdowns, as follows in mid 2000, Promedica was notified to stop
work on the project. Subjects enrolled in the study continued to be followed by
study sites; however, field monitoring and all but essential data collection
activities were placed on hold, and management of study activities was taken
in-house.

In mid-2001, additional funding was received and Vascular Sciences requested
that Promedica resume work on the trial. Planned activities were organized into
two sequential phases, as follows:

The initial phase involved monitoring and data compilation for sites that
remained active since the trial was stopped. Work in this phase is substantially
complete.

The second phase involved activities associated with resumption of the study
utilizing an amended protocol and additional study sites. The current proposal
has been developed to cover services anticipated during this phase.

Promedica's proposal assumes that clinical study services provided will be
governed by Promedica's Standard Operating Procedures (SOPs), with the exception
that Vascular Sciences will have responsibility for quality assurance audits of
Promedica' management and administration of project activities.

The proposed project Scope of Work, along with associated estimated fees and
expenses, is organized as follows:

-     Ongoing Study Activities

      Included, are revisions to clinical and administrative databases, updates
      to project and monitoring plans, site initiation activities, site
      monitoring visits, ongoing site management activities, clinical data
      collection, compilation and management; and maintenance of project systems
      and controls.

-     Study Close out Activities

      This section includes collection of site closeout documentation, as data
      cleaning/database lock for generation of the final study report, and site
      closeout visits.

Promedica has significant previous experience with ophthalmology device trials,
and has established systems and personnel to facilitate management and execution
of this project.

SCOPE OF WORK

Following is a detailed assignment of responsibilities for this project. Please
reference Attachment 1 for assumptions and Promedica's associated estimated
budget. In the event that assumptions change during the course of this project,
actual fees and expenses will be based on the terms set forth in Attachment 2
(Pricing Schedule & Travel Expense Guidelines) of this document.

1.    Sponsor is responsible for amendments to study protocol and Case Report
      Forms (CRFs), along with Informed Consent Document (ICD) template.
