applicable, shipped to a customer or End User by or for MIRAI. MIRAI shall
further include the End User Licenses and Terms and Conditions on every Luminex
System, Kit and [__]* in the manner prescribed by LUMINEX. LUMINEX shall have
the right to change such End User Licenses and Terms and Conditions on 30 days

legally bind such customers and End Users to the End User Licenses and Terms and
Conditions.

3.6     Subdistributors. Subject to all the terms and conditions herein, each of
MIRAI, HSW and DNACR, as agents for MIRAI, may appoint Kit Subdistributors to
(i) develop and sell Kits and Tests in accordance with the provisions of Article

such action as shall be reasonably necessary to advise each such Subdistributor
of MIRAI's confidentiality and intellectual property obligations under this
Agreement, (ii) use reasonable commercial efforts to include in any agreement or
contract with such Subdistributors terms and conditions substantially similar to
those set forth in this Agreement and a provision expressly making LUMINEX a

(iv) indemnify and hold LUMINEX harmless from and against any claims, causes of
action, costs, losses or liabilities incurred by LUMINEX as a result of any such
breach, violation, improper use, infringement or misappropriation. LUMINEX

remedies against any Subdistribution. Except as expressly provided in this
Section 3.6 and Section 12.4, neither MIRAI, HSW nor DNACR shall have any right
to assign or sublicense its rights or appoint subdistributors hereunder.

3.7     To LUMINEX. MIRAI hereby grants to LUMINEX a nonexclusive, perpetual
worldwide, unrestricted license, with the right to grant and authorize

purchase order, and shall provide for shipment in accordance with LUMINEX's
standard lead times, currently six to eight weeks, then in effect. For
quantities of Luminex 100 Systems and Beads conforming to Forecasts, LUMINEX
will use its reasonable commercial efforts to ship such quantities within two
(2) weeks from receipt of the order. ANY TERMS OR CONDITIONS OF ANY PURCHASE
ORDER, ACKNOWLEDGMENT OR SIMILAR STANDARDIZED FORM GIVEN OR RECEIVED PURSUANT TO
THIS AGREEMENT WHICH CONFLICT OR ARE INCONSISTENT WITH THE TERMS OF THIS
AGREEMENT SHALL HAVE NO EFFECT AND SUCH TERMS AND CONDITIONS ARE HEREBY
EXCLUDED. FOR THE AVOIDANCE OF DOUBT, SUCH TERMS SHALL BE EXCLUDED
NOTWITHSTANDING THE FACT THAT ANY SUCH PURCHASE ORDER, ACKNOWLEDGEMENT OR
SIMILAR STANDARDIZED FORM MAY (1) HAVE COME INTO EXISTENCE AFTER THE EFFECTIVE

shipment, the purchase order number, and the nature of the discrepancy between
the order and the shipment or the nature of the discrepancy in the shipping or
other charges, as applicable. LUMINEX agrees to replace, at no additional
expense to MIRAI, any Beads and Luminex Systems which fail to conform in any
material respect (i.e., provide substantially the same functionality) to the
Bead Specifications or Luminex System Specifications, respectively, with Beads
and Luminex Systems which conform to the Bead Specifications or the applicable
Luminex System Specifications, respectively. LUMINEX may analyze any Beads and
Luminex Systems rejected by MIRAI for nonconformity and if it is objectively
established that the Beads and Luminex Systems were conforming in all material
respects, then MIRAI shall be responsible for payment for such Beads and Luminex
Systems. MIRAI shall, at LUMINEX's option, return to LUMINEX or destroy, and
provide written certification of destruction, all Beads which do not conform in
all material respects to the then current, published Bead Specifications, and
MIRAI shall return to LUMINEX all Luminex Systems which do not conform in all
material respects to the then current, published applicable Luminex System
Specifications. All returns shall be in accordance with LUMINEX's written
instructions and shall be at LUMINEX's expense if the Beads and Luminex System
are confirmed by LUMINEX as not conforming in all material respects to the then
current, published applicable Luminex System Specifications.

4.5     Pricing and Royalties.

               (a)    Bead Pricing. MIRAI shall pay LUMINEX [__]* of the then

               (b)    Luminex System Pricing. MIRAI shall pay to LUMINEX [__]*
of the then effective full list price for each Luminex System (collectively, the
"System Price"), except that if MIRAI earns [__]* Field Credits during a
calendar year, LUMINEX will refund to MIRAI [__]* of the LUMINEX list price paid
by MIRAI for each Luminex Systems sold during that calendar year.

               (c)    Direct Royalties. MIRAI shall pay to LUMINEX a royalty
("Direct Royalties") equal to [__]* of Net Sales generated from MIRAI's sale of
Kits and Tests.

               (d)    Indirect Royalties. Each Kit Subdistributor shall pay to
MIRAI a royalty ("Subdistributor Royalties") measured as a percentage of Net
Sales generated from such Kit Subdistributor's sale of Kits and Tests. MIRAI
shall pay to LUMINEX a royalty ("Indirect Royalties") equal to the greater of
(i) [__]* of the Subdistributor Royalties or (ii) [__]* of the Net Sales
generated from such Kit Subdistributor's sale of Kits and Tests, as and when the
Subdistributor Royalties are received by MIRAI from Kit Subdistributors. MIRAI
shall use reasonable commercial efforts to collect all Subdistributor Royalties
from Kit Subdistribution. In addition, if a Kit Subdistributor pays an up-front
payment, MIRAI shall pay LUMINEX (i) [__]* of the first [__]* of each such
payment and (ii) [__]* of any amount in excess of [__]* of each such payment.

        4.6    Conflicts of Interest. It is understood and agreed that MIRAI may
sell Kits and Tests, the Luminex System [___]* to End Users or Subdistributors

market, promote or distribute Kits, Tests or the Luminex Systems in a manner
that would disadvantage the Kits, Tests or the Luminex Systems in comparison
with such other products or services marketed by MIRAI.

        4.7    Invoices. LUMINEX shall submit an invoice to MIRAI upon shipment
of Beads or Luminex Systems ordered by MIRAI hereunder to the following address:
1201 Harbor Bay Parkway, Suite 150, Alameda, California 94502, or such other
address as specified in the purchase order therefor, and each such invoice shall
state the fees due for Beads or Luminex Systems in a given shipment, plus any
insurance, taxes or other costs incident to the purchase or shipment initially
paid by LUMINEX but to be borne by MIRAI hereunder.

        4.8    Reporting and Payment. Unless otherwise agreed in writing by
LUMINEX, payment of the Bead Prices and the System Prices to LUMINEX shall be
made within thirty (30) days of MIRAI's receipt of an invoice therefor. Payment
of the Direct Royalties and the Indirect Royalties shall be made within [__]*
days after the end of each calendar quarter, and shall be accompanied by a
written report stating the Net Sales generated in the prior calendar quarter,
the total Direct Royalties and Indirect Royalties due and all supporting data
and calculations used by MIRAI to compute Direct Royalties and Indirect
Royalties. In addition, MIRAI shall provide LUMINEX with a quarterly report of
estimated Direct Royalties and Indirect Royalties within 15 days after the end
of each calendar quarter; provided, however, that the failure to provide any
such report shall not be deemed to be a breach of this Agreement. All payments
hereunder shall be made in U.S. Dollars in the United States by: (i) direct bank
transfer to a LUMINEX account, (ii) check, or (iii) other form of payment
acceptable to and approved in advance by LUMINEX. In the event that MIRAI is
unable to make such payments in the United States, due solely to its inability
to export funds from a country within the applicable Territory, MIRAI shall
notify LUMINEX immediately, and if so instructed by LUMINEX, deposit all monies
due LUMINEX in an account of LUMINEX in a local bank of LUMINEX's choice within
the applicable Territory. Any late payments shall bear interest at the rate of
one percent (1.0%) per month or the highest rate permitted under applicable law,
which ever is less, based on the number of days overdue.

4.9     Taxes.

               (a)    Any and all amounts payable hereunder do not include any
government taxes (including, without limitation, sales, use, excise, and value
added taxes) or duties imposed by any governmental agency that are applicable to
the export, import, or purchase of the Beads or the Luminex Systems (other than
taxes on the net income of LUMINEX), and MIRAI shall bear all such taxes and
duties. When LUMINEX has the legal obligation to collect and/or pay such taxes,
the appropriate amount shall be added to MIRAI's invoice and paid by MIRAI,
unless MIRAI provides LUMINEX with a valid tax exemption certificate authorized
by the appropriate taxing authority.

               (b)    All payments by MIRAI specified hereunder are expressed
as net amounts and shall be made free and clear of, and without reduction for,
any withholding taxes. Any taxes which are otherwise imposed on payments to
LUMINEX shall be the sole responsibility of MIRAI. MIRAI shall provide LUMINEX
with official receipts issued by the appropriate taxing authority or such other
evidence as is reasonably requested by LUMINEX to establish that such

                                      -12-

taxes have been paid. If LUMINEX uses a foreign tax credit received by LUMINEX
as a result of the payment of withholding taxes by MIRAI and thereby reduces the
amount of U.S. income tax that LUMINEX otherwise would have paid, LUMINEX shall
refund to MIRAI the amount of such reduction with respect to such foreign tax
credit.

4.10    Currency Conversion. If any currency conversion shall be required in
connection with the calculation of amounts payable under this Agreement, such
conversion shall be made using the selling exchange rate for conversion of the
foreign currency into U.S. Dollars, quoted for current transactions reported by
The Wall Street Journal (New York Edition) for the last business day of the
calendar month to which such payment pertains.

4.11    Records; Inspection. MIRAI shall keep complete, true and accurate books
of accounts and records for the purpose of determining the amounts payable under
this Article 4 for at least three (3) years following the end of the calendar
quarter to which they pertain. Such books and records will be open for
inspection during such three (3)-year period by an independent auditor chosen by
LUMINEX at MIRAI's site for the purpose of verifying the amounts payable by
MIRAI under this Article 4. Such on-site inspections may be made no more than
once each calendar year, at reasonable times and on reasonable notice.
Inspections conducted under this Section 4.11 shall be at the expense of
LUMINEX, unless a variation or error producing an underpayment in amounts
payable exceeding five percent (5%) of the amount paid for any period covered by
the inspection is established in the course of any such inspection, whereupon
all costs relating to the inspection for such period and any unpaid amounts that
are discovered shall be paid by MIRAI, together with interest as specified in
Section 4.8 above. The parties will endeavor to minimize disruption of MIRAI's
normal business activities.

        4.12   Forecasts. Within 30 days prior to the end of each calendar
quarter, MIRAI shall provide LUMINEX a rolling six-month forecast of delivery
requirements of Beads and Luminex 100 Systems for the next two succeeding
calendar quarters ("Forecast"). The Forecasts shall constitute MIRAI's good
faith estimates of MIRAI's requirements, but shall be nonbinding upon either
party.

                                   ARTICLE 5
                              COMPLIANCE WITH LAWS

        MIRAI shall develop and distribute Kits, and distribute [__]* Luminex
Systems, in accordance with all federal, state, local and foreign laws and
regulations pertaining thereto and shall be responsible for securing and
maintaining required regulatory approvals at MIRAI's expense. MIRAI shall be
responsible for complying with all directives, laws, rules and regulations
relating to the performance of MIRAI's obligations and exercise of MIRAI's
rights hereunder, including without limitation, regulatory reporting
regulations, and further shall be responsible for all activities relating to
recalls. MIRAI agrees to cooperate with LUMINEX, including without limitation,
providing required documentation, in order to obtain export licenses or
exemptions therefrom. MIRAI warrants that it will comply with applicable laws
and regulations governing imports and exports in effect from time to time.

LUMINEX will provide the necessary parts to MIRAI or HSW at no charge. [__]*

        6.2    Software Errors. MIRAI acknowledges that inevitably some errors
("bugs") may exist in the Software, and the discovery of the presence of such
bugs shall not be a breach of this Agreement. In the event that MIRAI finds a
bug in the Software, MIRAI shall notify LUMINEX in writing (or by fax or
electronic mail) and shall provide LUMINEX adequate information about the bug
and the circumstances under which it was found. LUMINEX's sole obligation, if it
concurs that MIRAI's finding is a bug, shall be to correct such bug, without
additional compensation, as soon as is reasonably possible.

        6.3    Training. At MIRAI's request, LUMINEX will provide a two-day

        6.4    Service Contracts. MIRAI and its Subdistributors shall have the
right to offer service contracts for Luminex Systems to customers who have
purchased a Luminex System from them. In providing front-line maintenance and

shall use only parts and components authorized by LUMINEX, which LUMINEX agrees
to provide to MIRAI and its Subdistributors at LUMINEX's standard or list prices
in effect from time to time.

                                   ARTICLE 7

either party by written notice of termination effective immediately (i) if the
other party breaches any material term or condition of this Agreement and fails
to remedy the breach within thirty (30) days after being given written notice
thereof stating the nonbreaching party's intent to terminate; or (ii) in the
event that any current legislation or exchange controls under applicable law
preclude MIRAI from making payments to LUMINEX in United States currency for a
period of sixty (60) days, provided, however, that termination under this
subsection 8.2 (ii) shall not relieve MIRAI of its payment obligations under
this Agreement.

        8.3    Effect of Termination. MIRAI may at MIRAI's option (i) sell
Luminex Systems, [__]* and Kits existing in its inventory as of the effective

                               LUMINEX TRADEMARKS

        9.1    Trademarks. Subject to the provisions of this Article 9, during
the term of this Agreement, MIRAI and its authorized Subdistributors shall

from time to time ("LUMINEX's Trademarks"), in a manner agreed upon in writing
by the parties. Branding of Kits, [__]* Luminex Systems shall be subject to
LUMINEX's prior inspection and written approval. MIRAI shall not modify
LUMINEX's branding of Luminex Systems except by mutual agreement. LUMINEX agrees
to co-brand the Luminex 100 Systems in a mutually agreeable manner; provided,
that the System Price shall be increased for LUMINEX's cost of such co-branding
unless the co-branding only consists of standard labeling of the Luminex Systems
with MIRAI's trademark. All representations of LUMINEX's Trademarks that MIRAI
intends to use shall first be submitted to LUMINEX for approval (which shall not
be unreasonably withheld) of design, color and other details, or shall be exact
copies of those used by LUMINEX. MIRAI shall fully comply with all guidelines,
if any, communicated by LUMINEX concerning the use of LUMINEX's Trademarks.
LUMINEX may modify any of LUMINEX's Trademarks, or substitute an alternative
mark for any of LUMINEX's Trademark, upon sixty (60) days' prior notice to
MIRAI.

        9.2    Use. MIRAI shall not alter or remove any of LUMINEX's Trademarks
affixed to or otherwise contained on or within the Luminex Systems, Beads or
packaging or documentation therefor, except by mutual agreement. All uses of
LUMINEX's Trademarks will inure solely to LUMINEX, MIRAI shall obtain no rights
with respect to any of LUMINEX's Trademarks, other than as expressly set forth
herein, and MIRAI irrevocably assigns to LUMINEX all such right, title and
interest, if any, in any of LUMINEX's Trademarks. At no time during or after the
term of this Agreement may MIRAI challenge or assist others to challenge
LUMINEX's Trademarks (except to the extent expressly required by applicable law)
or the registration thereof or attempt to register any trademarks, marks or
trade names confusingly similar to those of LUMINEX. LUMINEX and MIRAI shall
enter into registered user agreements with respect to the LUMINEX's Trademarks
pursuant to applicable trademark law requirements worldwide. MIRAI shall be
responsible for proper filing of the registered user agreement with government
authorities for those countries listed in the applicable Territories and shall
pay all costs or fees associated with such filing.

                                 INDEMNIFICATION

11.1    LUMINEX Indemnity. LUMINEX shall defend and/or settle any claim,
complaint, suit, proceeding or cause of action (collectively and individually
referred to as a "Claim") brought against MIRAI by a third party for
infringement of any third party, patent trademark, copyright or other
intellectual property right issued as of the Effective Date by the Beads and
Luminex Systems, as delivered by LUMINEX hereunder, subject to the requirements
of this Section 11.1 and Section 11.2 below. LUMINEX shall pay all resulting
damages or settlement amounts finally awarded against MIRAI (including
reasonable attorneys' fees, legal expenses and court costs) to the extent
attributable to such Claim. Notwithstanding the provisions of this Section 11.1,
LUMINEX will not have any obligation under this Article 11 to the extent a Claim
for infringement is based upon (i) indirect or contributory infringement, (ii) a
modified Luminex System, modifications to any portion thereof or modifications
to Beads, if such infringement would have been avoided by use of the Luminex
System or Beads as provided by LUMINEX, (iii) completed products or equipment or
any assembly, combination, method or process in which the Luminex System and
Beads are used, to the extent the infringement would not have resulted

if the Luminex System and Beads were used alone, (iv) continuation of allegedly
infringing activity after being provided modifications that would have avoided
the alleged infringement without materially altering the functionality of the
Luminex System and Beads, or (v) the making, using, selling, offering for sale
or importation of Developed Kits or Tests. MIRAI shall

(i) promptly notify LUMINEX of each Claim, (ii) provide LUMINEX with sole
control over the defense and/or settlement thereof, and (iii) at LUMINEX's
request and expense, provide full information and reasonable assistance to
LUMINEX with respect to such Claims.

11.2    Alternatives. Without limiting Section 11.1 above, if the Beads or
Luminex Systems or any portion thereof is or in LUMINEX' reasonable judgment may
become the subject of any Claim of infringement of third party intellectual
property rights, or if a court determines that the Beads or Luminex Systems or
any portion thereof infringes any third party intellectual property rights,
LUMINEX, at its option and expense, may (i) procure for MIRAI the right under
such third party intellectual property rights to use the Luminex Systems or
Beads in accordance with the terms and conditions of this Agreement; or (ii)
replace the infringing portion of the Luminex Systems or Beads with other
suitable noninfringing product having functionality substantially the same as
the infringing portion of the Luminex System or Beads so replaced; or (iii)
modify the Luminex System or Beads to make the same noninfringing; or (iv) in
the event (i), (ii) or (iii) above are not commercially practicable in LUMINEX's
judgment, require that MIRAI remove the Luminex Systems and/or Beads or any
portion thereof from use at LUMINEX's expense, in which event LUMINEX may
terminate this Agreement by written notice to MIRAI.

11.3    Entire Liability. EXCEPT FOR ANY ACTIONS GOVERNED BY LAWS OF THE UNITED

ADDITIONALLY, IF WITHDRAWAL OF LUMINEX SYSTEMS FROM THE MARKET IS REQUIRED AS
THE RESULT OF AN INFRINGEMENT CLAIM, [__]*. THE FOREGOING PROVISIONS OF THIS

EXCLUSIVE REMEDY OF MIRAI WITH RESPECT TO ANY ALLEGED INFRINGEMENT OF PATENT
RIGHTS, TRADE SECRETS, COPYRIGHTS OR OTHER INTELLECTUAL PROPERTY RIGHTS WITH
RESPECT TO THE LUMINEX SYSTEM, BEADS, KITS OR ANY PORTION THEREOF.

11.4    Indemnification. Subject to the foregoing provisions of this Article 11,
each Party (the "First Party") shall, except to the extent that the same can be
shown to have been caused by the other (the "Second Party") or its Affiliates or
its or their agents (including in the case of MIRAI all Subcontractors and
Subdistributors), defend, indemnify and save harmless the Second Party and its
Affiliates and the directors, officers, employees, and agents of the Second
Party and its Affiliates (the "Indemnified Parties") from and against any and
all claims, liabilities, losses, damages or expenses (including but not limited
to reasonable attorneys' fees and other costs of defending any action) that the
Second Party may sustain or incur as a result of (i) any claim of negligence,
breach of implied warranty, strict liability in tort, or other theory of law,
based upon acts or omissions of the First Party or any of its Affiliates or
agents or the directors, officers, agents, or employees of any of the foregoing
and resulting from, or in any way arising out of or related to, the manufacture,

     conditions of any type may not be disclaimed, any such warranty, guaranty,
     representation and/or condition is hereby limited to the period of either
