INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND FILED SEPARATELY WITH THE
COMMISSION.  CONFIDENTIAL TREATMENT HAS
BEEN REQUESTED WITH RESPECT TO THE OMITTED PORTIONS.  WNV Association Agreement  This WNV Association
Agreement (this WNV Association Agreement) is made effective as of July 1,
2003, between Americas Blood Centers (ABC), a charitable and non-profit
corporation, having its principal office at 725 15th Street, N.W.
Suite 700, Washington, D.C. 20005, and Chiron Corporation, a Delaware
corporation (Chiron) having its offices at 4560 Horton Street, Emeryville,
California 94608-2916.  Background  A.WHEREAS, ABC is an association of
non-profit community-based
centers (each such blood center, a Member);  BWHEREAS,
Members currently screen for themselves and for other blood banks in the United
States, human blood samples for viruses such as Human Immunodeficiency Virus
type-1 (HIV-1)
and Hepatitis C Virus (HCV) by performing screening using
amplified nucleic acid screening;  C.WHEREAS, Chiron and ABC are parties to that certain
Association Agreement Regarding Sale and Servicing of Blood Screening Products
effective as of May 1, 2002 (the 2002
Association Agreement), pursuant to which Chiron sells to
Participating Members, and Participating Members purchase from Chiron, certain
assays and blood screening instruments to conduct nucleic acid amplification
screening to detect the presence of certain viruses in blood, including HIV-1
and HCV;  D.WHEREAS,
Chiron, together with its collaboration partner, Gen-Probe, Incorporated
(Gen-Probe)  is developing a WNV Assay which can be used
to conduct amplified nucleic acid tests to detect the West Nile Virus (WNV) in pooled and single donor blood
products (the WNV Assay);  E.WHEREAS,
Further development and testing of the WNV Assay is necessary before
Chiron and Gen-Probe may seek to obtain FDA approval for the commercial
distribution and use of such WNV Assay;  F.WHEREAS, The costs and efforts required for
such further development and testing far exceed those that Chiron and Gen-Probe
will undertake without assistance and collaboration from other entities, and
the absence or delay of such assistance and collaboration of those entities
would significantly delay the further development and testing, and, thus, the
availability to Members of the WNV Assay;  1

parties shall agree upon a single arbitrator. 
If the parties are unable to agree on an arbitrator, then they will
obtain nominations of three (3) potential arbitrators who are retired federal or
state judges and each party will have the right to strike one candidates name
from the list.  11.6The prevailing party
shall be entitled to recover all costs and expenses, including reasonable
attorneys fees, incurred because of any legal action arising in relation to

in performance or from failure to perform in accordance with the terms of this
Agreement, to the extent that such delay or failure to perform results from a
Force Majeure Event. The provisions of this paragraph shall apply only if such
party shall have used its reasonable efforts to avoid such Force Majeure
Event.  Such party shall give notice to
the other promptly in writing upon learning of the Force Majeure Event.  The affected partys time for performance
shall be extended for the period of the delay or inability to perform due to
such Force Majeure Event and notwithstanding any provision herein to the
contrary, the affected party shall not be liable for any Damages arising out of

Agreement. This Agreement
constitutes the entire agreement between the parties in respect of the subject
matter hereof.  This Agreement cancels
and supersedes any and all pre-existing agreements, either oral or in writing
between the parties.  There are not and
shall not be any oral statements, representations, warranties, undertakings or
agreements between the parties other than as provided by this Agreement and any
mutually accepted written amendments hereto. 
For the avoidance of doubt nothing in this Agreement amends, modifies,
cancels  16 
   or
supercedes the 2002 Association Agreement or any 2002 Member Supplement.  12.8No
Waiver.  The failure on the part of either party
hereto to exercise or enforce any right conferred upon it by this Agreement
shall not be a waiver of any such right nor shall any single or partial
exercise of any right or power hereunder or further exercise thereof operate so
as to bar the later exercise or enforcement thereof.  12.9Nature
of Relationship.  Nothing herein contained shall be deemed to
be or construed as constituting either party the agent or partner of the other
party.  The relationship between Chiron
and each Participating Member shall be that of an independent contractor.  No party shall have the right, title or
authority to enter into any contract, agreement or commitment on behalf of the
other or to bind the other party in any manner whatsoever.  In no event shall ABC have any
responsibility for the financial obligations of any Participating Member, nor
shall any Participating Member have any responsibility for the financial
obligations of any other Participating Member.  12.10Conflict
Between Terms and Conditions.  In the event of any conflict between the
terms and conditions of this WNV Association Agreement and any terms and
conditions that may be set forth in a WNV Member Supplement or on any invoice
or purchase order or other similar document relating to the Products, the terms
and conditions of this WNV Association Agreement govern.  For the avoidance of doubt no term or
condition contained in the 2002 Association Agreement or any 2002 Member
Supplement amends, modifies, cancels or supercedes the terms and conditions of
this Agreement with regard to the Products.  12.11Compliance with
Applicable Law.  In performing this
Agreement, the parties shall comply with all applicable laws.  Nothing in this Agreement shall be construed
so as to require the violation of law, and wherever there is any conflict
between any provision of this Agreement and any rule of mandatory law, the
latter shall prevail, but in such event, the affected provision of this
Agreement shall be ineffective only to the extent necessary to comply with the
applicable law, and the parties hereto undertake to replace the invalid and/or
unenforceable provision by a valid and/or enforceable provision, the nature and
scope of which will come as close as possible to the contractual provision to
be replaced.  12.12Counterparts.  This WNV Association Agreement and any WNV
Member Supplement may be executed in two or more counterparts, each of which
shall be deemed to be an original and each of which shall constitute one and
the same Agreement.  12.13Severability.  In the event that any provision of this
Agreement is found to be invalid or  in
conflict with any applicable law or regulation, the affected provision of this
Agreement shall be limited or eliminated only to the extent  17 
   necessary to comply with
such law or regulation, and the remainder of this Agreement shall remain in
full force and effect, provided that the remainder of this Agreement is
consistent with the economic intentions of the parties as evidenced by this
Agreement as a whole.  12.14Publicity.  Neither Party shall permit or generate any publicity,
advertising or promotion concerning this Agreement without the prior written
consent of the other Party.  Each Party
recognizes that the name, logo and marks of the other Party represent valuable
assets of that Party and that substantial recognition and goodwill are
associated with such assets.  Each Party
hereby agrees that neither it nor any of its Affiliates shall use the other
Partys name, logo or marks without the prior written authorization from such
other Party.  Notwithstanding any other provisions
of this paragraph, it is agreed that the parties may, without prior approval of
any other party, make factual, non-promotional statements (a) that WNV testing
will be and/or is being performed by Participating Members, (b) as to the
source of the WNV Assays, and (c) as to costs of WNV testing that will have to
be passed along, so long as the specific financial terms of this Agreement are
not discussed.  Each
of the Parties acknowledges that a violation of this Section 12.14 would cause
irreparable harm to the other Party for which no adequate remedy at law exists
and each Party therefore agrees that, in addition to any other remedies
available, and notwithstanding any other provision of this Agreement, the
aggrieved Party shall be entitled to injunctive relief to enforce the terms of
this Section 12.14.  To the extent
allowed by law, the prevailing Party shall be entitled to recover all costs and
expenses, including reasonable attorneys fees, incurred because of any legal
action arising in relation to this Section 12.14.  12.15Disclosure of Agreements and Terms.  Subject to mutual agreement as
to form and substance, each of the Parties may issue a press release disclosing
the existence of this Agreement.  Each
Party may disclose any of the terms of this Agreement to any Affiliate;
provided that the recipient of such disclosure is obligated to confidentiality
terms no less restrictive than those contained in Section 6.7.  Each Party may disclose any information
contained in or regarding this Agreement to the extent required in its
respective reasonable judgment by applicable law, regulation or order of any
court or governmental agency.  Further,
each Party may determine in its respective discretion to file this Agreement
under the Securities and Exchange Act of 1934, even if that filing may result
in this Agreement becoming available to the public generally.  The filing Party shall seek confidential
treatment for at least the essential financial terms hereof in connection with
any such filing, subject to applicable law and regulation, and shall notify the
other Party in advance of any such filing and consider such suggestions as the
other Party may make as to the terms herein as to which the filing party should
seek confidential treatment.  18

   SCHEDULE B  TERMS AND
CONDITIONS FOR PROVISION OF WNV ASSAY  1.Supply, Handling and Storage Obligation. 
During the Term of this Agreement Chiron agrees to supply to
Participating Members the WNV Assays to permit each Participating Member to
conduct screening of blood donations in the Territory.  Participating Members agree to store and
handle all WNV Assays in accordance with the applicable Package Insert.  Any WNV Assays lost or damaged due to
failure to comply with such storage and handling instructions will be replaced
at the Participating Members expense.  2.Packing and
Delivery of WNV Assays.  All WNV
Assays will be suitably packed and transported to ensure safe transport to the
Participating Members in accordance with the manufacturers instructions and
delivered Carriage and Insurance Paid to the Participating Members designated
Testing Centers, and each delivery will be accompanied by a packing slip
indicating the quantity delivered.  WNV
Assays will be delivered during normal business hours and accompanied by
storage instructions and arrive at the temperatures specified by the
manufacturer and set out in the Package Insert.  The WNV Assays will be delivered in kit form, with appropriate
distribution between screening tests, discriminatory tests and related
calibrators.  3.Shipping.
Except as set forth below, all shipping and handling charges for the regular
monthly shipments of WNV Assays will be borne entirely by Chiron on shipments
to the Testing Centers.  All shipping
and handling charges for shipping requests other than to a Testing Center, and
all incremental shipping and handling charges for Modified Orders and Changed
Orders, will be borne by the requesting Participating Member.  4.Forecasts and
Orders.  4.1Each Participating
Member will provide Chiron with a written twelve month forecast of its
requirements of WNV Assays (each a Product Requirements Forecast) on an
annual basis, including requested delivery dates, which forecast shall
constitute such Participating Members standing firm purchase order for each
month contained therein.  Not less than
ninety (90) days prior to each anniversary of the effective date of the
applicable WNV Member Supplement, each Participating Member will provide such a
Product Requirements Forecast.  Participating
Members shall deliver any modifications to the standing firm purchase order for
WNV Assays for delivery during the next following month on or prior to the
first day of the immediately preceding calendar month (for example, a
Participating Member will provide requested modifications to the February
standing firm purchase orderfor deliveries to be made during the month of
Februaryprior to January 1).  All
purchase order modification requests  26 
   must be received at least
30 days prior to a requested delivery date. 
Except as otherwise agreed, Chiron agrees to accept modifications to
standing firm purchase orders which do not differ by more than [***]
from the quantities forecast for delivery in the applicable month in the
current Product Requirements Forecast. 
Participating Members may further adjust their Product Requirements
Forecast from time to time with the consent of Chiron, such consent to not be
unreasonably withheld.  4.2If the variance between
the modification requested and the current Product Requirements Forecast
exceeds the [***] referenced in Section 4.1 of this Schedule B,
Chiron will notify the requesting Participating Member within five (5) business
days after receipt of the modification request as to whether it accepts such
modification request.  If a modification
request is accepted, Chiron agrees to deliver such amounts of WNV Assays on the
delivery date(s) stated.  If a
modification request is not accepted, the parties will use all reasonable
endeavors to agree on further modifications to the order and/or delivery date
(a Modified Order), subject to Chirons manufacturers accommodating Chirons
requests for changes in forecasted amounts.  5.Changes to Orders.  If a Participating Member requests any
modifications to quantities of WNV Assays ordered or the delivery schedule or
locations reflected in such order within 30 days of a delivery date (a Changed
Order), Chiron will use reasonable commercial efforts to comply with such
request.  6.IQA Procedures.  Prior to the initial delivery of WNV Assays,
Chiron, ABC and the Participating Members shall mutually agree upon procedures
for quality assurance testing of WNV Assays received by Participating Members
(IQA Procedures).  Chiron agrees to
replace WNV Assays which fail to conform to the specifications as set forth in
the Package Insert.  The IQA Procedures
shall include procedures for notice to Chiron and for implementing the return
of WNV Assays for replacement.  If
testing by Chiron or its supplier confirms the non-conformity of the WNV
Assays, Chiron will bear the shipping costs associated with replacement.  If Chirons testing provides reasonably
acceptable evidence to the applicable Participating Member that the WNV Assays
do conform to the specifications in question, the shipping costs will be borne
by the applicable Participating Member.  7.Nature of Testing. 
Each Participating Member will determine, in its sole discretion,
whether to use the WNV Assays supplied by Chiron hereunder  to conduct Pooled Testing or Single Donor
Testing.  If a Participating Member
desires to change its testing from Pooled Testing to Single Unit Testing or any
other pool size, the Participating Member and Chiron shall enter into an
addendum to the applicable WNV Member Supplement reflecting any additional
instrumentation or any other amendments that may be applicable by reason of
such change.  27
