such four (4) year period. If the inspection discloses that Caliper was
underpaid royalties by at least [ * ] for any Contract Quarter, then Bio-Rad
shall reimburse Caliper for any documented and reasonable costs associated with
the inspection, together with an amount equal to the additional royalties to
which Caliper is entitled as determined by the inspection.

         2.6      Withholding Taxes. In the event that Bio-Rad is required to
withhold taxes under the laws of any foreign country for the account of Caliper,
then such payments will be made by Bio-Rad on behalf of Caliper to the
appropriate governmental authority, and Bio-Rad shall furnish proof of payment
of such tax together with official or other appropriate evidence issued by the
appropriate government authority. Any such tax actually paid on Caliper's behalf
shall be deducted from royalty payments then due and owing Caliper.

         2.7      Interest on Late Payments. Should Bio-Rad fail to make any
payment to Caliper within the time period prescribed for such payment, then the
unpaid amount shall bear interest at the lesser of (i) [ * ] or (ii) the

         3.3      Management of Development Workplans. Caliper and Bio-Rad shall
each designate a Project Manager who together shall jointly plan and oversee all
Development Workplan activities carried out under this Agreement, monitor the
progress of such activities, and prepare reports on such progress for the
Strategic Steering Committee. At the request of one Party's Project Manager (to
be made not more than once per Contract Quarter), the other Party's Project
Manager shall provide the requesting Project Manager with a confidential written
report, within thirty (30) days after such request is made, summarizing the
activities undertaken and the results achieved under the applicable Development
Workplan since the date of the last such written report. Each Party shall,
within ten (10) business days after the Effective Date, appoint its initial
Project Manager for development projects under this Agreement and notify the
other Party in writing as to whom such Party has designated as its Project
Manager hereunder. Either Party, in its sole discretion, may replace its Project
Manager by delivering written notice to the other Party. The Parties shall
coordinate their efforts through the Project Managers for each Development
Workplan, but each Party shall be solely responsible for managing the personnel
and other resources it allocates to performing its designated tasks under each
Development Workplan.

         3.4      Reports to SSC; Amendment of Development Workplans. Unless
each of the Parties otherwise agrees, for so long as there are any ongoing
activities under an approved Development Workplan, the Project Managers shall
meet at least once per calendar quarter with the Strategic Steering Committee to
report on the activities undertaken and the results achieved under each
outstanding Development Workplan, including project milestones achieved, project
resourcing, and project management. The members of the Strategic Steering
Committee shall assess the progress of each Development Workplan, and discuss
any amendments proposed by either Party to any of the outstanding Development
Workplans. Amendments or other modifications of approved Development Workplans
may be made only with the unanimous written approval of the Strategic Steering
Committee.

         3.5      Termination of Development Workplans.

Workplan shall include, for the product covered by such Development Workplan,
phases for Definition and Feasibility, Development, and Commercialization.
Transition from one Development Workplan phase to the next will require
successful completion of required milestones, as determined by the Strategic
Steering Committee. Each Party will be entitled to terminate further work on a
Development Workplan at the completion of the Definition and Feasibility phase
and at the completion of the Development phase. If a Development Workplan is
terminated by either Party at the end of the Definition and Feasibility phase,
neither Party will have any obligations to the other Party with respect to the
further development or commercialization of the System covered by the terminated
Development Workplan. If a Development Workplan is terminated by one Party at
the end of the Development phase, and the other Party desires to continue the
development of the System covered by the terminated Development Workplan, the
Party terminating the Development Workplan shall [ * ]. In the event Caliper
terminates a Development Workplan after the Development phase and Bio-Rad
desires to continue with the commercialization of the subject System, Caliper
shall also [ * ].

                  3.5.2    Termination Due to Infringement. Notwithstanding
anything in this Agreement to the contrary, either Party may elect at any time
to cease developing any System pursuant to an approved Development Workplan if
(i) such Party reasonably determines, on advice of independent patent counsel
approved by both Parties, that the System contemplated by such Development
Workplan poses a substantial risk of infringing third party intellectual
property rights and (ii) either Party has not eliminated or substantially
mitigated such risk (either by obtaining a license from such third party or
modifying the System in a manner reasonably acceptable to each Party) within a
commercially reasonable time period. If one Party desires to continue the
development of the System covered by such terminated Development Workplan
notwithstanding the other Party's conclusions regarding third party
infringement, the Party terminating the Development Workplan shall [ * ]. In the
event Caliper elects to cease developing any System under this Section 3.5.2 and
Bio-Rad desires to continue with the commercialization of the subject System,
Caliper shall also [ * ]

                  3.5.3    Termination Due to Non-Performance. If one Party
fails to substantially perform under and in accordance with an approved
Development Workplan and if, within [ * ] after written notice of such
substantial non-performance by the performing Party, the non-performing Party
fails to remedy such non-performance, the performing Party shall have, in
addition to any other rights and remedies available under this Agreement, the
right to terminate such Development Workplan. In addition, [ * ]. [ * ]

                  3.5.4    Royalty Rate for [ * ]. Notwithstanding anything to
the contrary set forth in this Section 3.5, in the event that Caliper terminates
the Development Workplan for the [ * ] pursuant to either Section 3.5.1 or 3.5.2
and Bio-Rad desires to continue with the development and commercialization of
such System, [ * ]

                  3.5.5    Indemnification. In the event that a Party elects to
proceed with the development and commercialization of a System after the
termination of the Development Workplan for such System pursuant to Section
3.5.2, such Party shall defend, indemnify and hold harmless the other Party and
all of its officers, directors, employees and agents from and against any and
all damages, awards, costs and expenses (including court and arbitration costs,
witness fees and reasonable attorneys' fees) (collectively, "Losses") incurred
by any indemnified Party in connection with any claim, demand, law suit or other
legal action by any third party against such indemnified Party that arises from
or occurs as a result of development or commercialization of such System after
termination of the applicable Development Workplan, provided that no such
indemnification shall apply to the extent that such Losses arise from or occur
as a result of the negligence or intentional misconduct of an indemnified Party.

         3.6      Due Diligence; Exchange of Information. Upon the effectiveness
of any Development Workplan, Caliper and Bio-Rad agree to use [ * ] efforts to
perform the development activities as described in each Development Workplan, in
accordance with the terms of this Agreement and such Development Workplan, until
such Workplan is completed in accordance with the terms thereof or terminated in
accordance with Section 3.5. Without limiting the foregoing, each Party shall
assign such of its staff to each Development Workplan activity for which it has
responsibility as it shall deem appropriate, in its sole discretion, to fulfill
its responsibilities under this Agreement and such Development Workplan. Each
Party also shall share with the other Party relevant information in its

         6.9      Acceptance and Rejection of Products. All Caliper Products
delivered hereunder shall be [ * ] after the date of receipt of such Caliper
Products by Bio-Rad or its Affiliate from the carrier, Caliper receives written
notice of rejection from Bio-Rad or its Affiliate. Notwithstanding the
foregoing, no inspection or test of any Caliper Products by Bio-Rad or its
Affiliates shall relieve Caliper from its warranty obligations under section
6.15 and Bio-Rad's failure to inspect or test any Caliper Products shall not
constitute a waiver by Bio-Rad of any of its rights or remedies in respect of
any breach of warranty.

         6.10     Delivery of Caliper Products; Delivery Dates. The delivery
dates for all Caliper Products sold pursuant to this Agreement shall be deemed
to be the dates on which such Caliper Products are delivered into the possession
of the carrier designated by Bio-Rad, packed and ready for shipment to Bio-Rad,
or to a Bio-Rad Affiliate designated by Bio-Rad (subject to applicable minimum
order quantities). Caliper shall ship all Caliper Products [ * ]. If Caliper
shall fail to so deliver any Caliper Products purchased by Bio-Rad under this
Agreement within the lead-time for such Caliper Products specified in this
Agreement, Caliper shall immediately inform Bio-Rad of such failure by facsimile
notice, advise Bio-Rad of the reasons for such failure and the expected date of
delivery of the subject Caliper Products, and obtain Bio-Rad's instructions with
respect to the delivery of such Caliper Products to Bio-Rad. [ * ]

         6.11     Rejection or Cancellation of Orders. Caliper may reject any
order and may cancel any order previously accepted if Caliper reasonably
determines that such order will not be paid for in accordance with the terms and
conditions of this Agreement. Bio-Rad may only cancel orders with the written
consent of Caliper.

         6.12     Change of Caliper Products. Caliper shall have the absolute
right at any time and from time to time during the term of this Agreement, [ *

with such technical information regarding the Caliper Products (including
without limitation Material Safety Data Sheets) as Bio-Rad may reasonably
request from time to time during the term of this Agreement, provided that (i)
Caliper shall not be obligated to deliver to Bio-Rad any technical information
regarding the Caliper Products that Caliper reasonably considers to be a trade
secret or otherwise proprietary to Caliper and (ii) Bio-Rad shall continue to be
solely responsible for determining the suitability of the Caliper Products for
any proposed application of the Caliper Products notwithstanding the delivery of
any such technical information to Bio-Rad, other than any

                                      -19-



applications for which Caliper and Bio-Rad have agreed in writing are suitable
applications for such Caliper Products.

         6.15     Warranty and Disclaimer; Remedy.

                  6.15.1   Warranty and Disclaimer. Caliper warrants the Caliper
Products delivered by it hereunder against faulty workmanship and use of
defective materials for a period equal to [ * ] from the date such Caliper
Products are delivered into the possession of the carrier designated by Bio-Rad
or its Affiliate, packed and ready for shipment to Bio-Rad or its Affiliate; [ *
]. Faulty workmanship and/or use of defective materials shall be hereinafter
referred to as a "deficiency" and shall include any failure of any Caliper
Product to conform to its applicable specifications. Such warranty is the only
warranty made by Caliper and it can be amended only by a written instrument
signed by a duly authorized officer of Caliper. Caliper's obligations are also
subject to the condition that Caliper shall have no liability whatsoever for any
deficiency unless (x) Caliper is notified in writing promptly [ * ] after
discovery by Bio-Rad of the alleged deficiency, which notice shall include a
detailed explanation of the alleged deficiency, (y) a representative sample of
the Caliper Products containing the alleged deficiency is promptly returned to
Caliper, and (z) Caliper's examination of such returned sample of Caliper
Products discloses to Caliper's reasonable satisfaction that such alleged
deficiency actually exists and occurred in the course of proper and normal use
and was not caused by accident, misuse, neglect, alteration or improper
installation, repair or testing. If any Caliper Products so prove to contain a
deficiency and Bio-Rad elects to have them replaced, Caliper shall have a
reasonable time to make such replacement. Bio-Rad shall dispose of any
nonconforming Caliper Products, at Caliper's expense, in accordance with the
written instructions of Caliper. THE FOREGOING WARRANTY IS IN LIEU OF ALL OTHER
WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING WITHOUT LIMITATION ANY IMPLIED
WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND OF ANY OTHER
OBLIGATION ON THE PART OF CALIPER, EITHER EXPRESS OR IMPLIED, WHETHER ARISING
UNDER ANY STATUTE, LAW, COMMERCIAL USAGE OR OTHERWISE, ARE HEREBY EXCLUDED.

                  6.15.2   Remedy for Breach of Warranty. Bio-Rad acknowledges
and agrees that Caliper's responsibility in the case of breach of the foregoing
warranty shall be for Caliper, [ * ] to provide a replacement for the Caliper
Products or portion thereof with respect to which such warranty is breached or
to return all payments made with respect to such Caliper Products or portion
thereof. [ * ]

                  6.15.3   Limitation of Liability. Caliper's liability and
obligations with respect to any claim pursuant to Section 6.15.1 shall in no
event exceed in the aggregate the total purchase price received by Caliper for
the Caliper Products delivered hereunder (or, in the case of obligations arising
from or relating to particular Caliper Products delivered hereunder, the
purchase price of such Caliper Products). Except as set forth in Section 8.1,
Caliper shall in no event be liable to Bio-Rad or any other Person, whether in
contract, strict liability, tort or otherwise, for loss of or damage to or loss
of use of facilities or other property, loss of revenue, loss of use of revenue,
loss of anticipated profits, or other punitive, special, incidental, indirect or
consequential damages of any kind whatsoever, or claims of any customers of
Bio-Rad or other

                                      -20-



claimants, resulting or arising from or relating to the sale of Caliper Products
pursuant to this Agreement or Caliper's performance of its obligations
hereunder.

         7.       CONFIDENTIALITY; PUBLICITY

         7.1      Confidential Information. During the term of this Agreement,
and for a period of [ * ] following the expiration or termination of this

software provided by either Party hereunder shall be maintained in confidence in
perpetuity. Each Party further agrees that it shall not use for any purpose not
authorized under this Agreement or disclose to any third party the Confidential
Information of the other Party, except that either Party may disclose
Confidential Information of the other Party on a need-to-know basis to its
directors, officers, employees, consultants and agents, and Bio-Rad may disclose
such information to its Affiliates to the extent that such Affiliates have
undertaken an obligation of confidentiality and non-use similar to this Section
7.1. Upon request from a Party, the other Party shall return to such Party any
and all tangible embodiments of the Confidential Information of such other Party
or its Affiliates except to the extent that a Party is expressly permitted to
use such Confidential Information pursuant to a license grant set forth in this
Agreement or otherwise and except as necessary to monitor its compliance with
its obligations under this section 7.1.

         7.2      Publicity. The Parties anticipate that upon execution and
delivery of this Agreement, each Party will issue a press release regarding the
collaboration established pursuant to this Agreement. However, neither Party
shall issue any press release or other public announcement relating to the
contents of this Agreement without the prior written approval of the other
Party, which approval shall not be unreasonably withheld, or delayed for longer
than five (5) business days. Notwithstanding the foregoing, either Party may
disclose the existence and/or the provisions of this Agreement (i) under
standard obligations of confidentiality and non-use on a need-to-know basis, to
investors and their representatives in a private or public financing
transaction, or to potential acquirers or targets and their representatives in a

be permitted to the extent it would constitute a violation of Section 7.1, or
(ii) as required by law (including but not limited to the filing of this
Agreement as an exhibit to a document filed with the Securities and Exchange
Commission), order or regulation of a governmental agency. The disclosing Party
shall provide written notice to the other Party of any such disclosure required
by law, order or regulation of a governmental agency, reasonably in advance of
such disclosure if practical. If either Party intends to file this Agreement
with the Securities and Exchange Commission, it shall provide the other Party
with the opportunity to review and comment on the proposed filing, and the
filing Party will incorporate the comments of the other Party subject only to
securities law requirements.

of Bio-Rad or its Affiliates, (ii) Bio-Rad's use of Caliper Products in

(the "Indemnifying Party") written notice of the relevant claim and the related
facts with reasonable promptness after becoming aware of same, (ii) reasonably
cooperate with the Indemnifying Party, at the Indemnifying Party's expense, in

participate in such defense through counsel of its own choosing.

good faith:

                  (a)      With respect to disputes arising between the Project

         have the right to refer the dispute to the Strategic Steering
         Committee, which shall attempt in good faith to negotiate a

                                      -25-



         resolution of such dispute within thirty (30) days. Any dispute that

         consider in good faith the analyses and opinions of any such
         independent experts engaged by either of them in making a
         determination. Any written resolution of the dispute agreed to by such
         officers shall be final and binding on the Parties.

                  (b)      If the executive officers have not succeeded in
         negotiating a written resolution of the dispute within the time
         allotted therefor, either Party shall have the right to take legal
         action in a court of law.

                  11.2.2   Interim Relief. Notwithstanding anything herein to
the contrary, nothing in this Section shall preclude either Party from seeking
interim or provisional relief, including a temporary restraining order,
preliminary injunction or other interim equitable relief concerning a dispute,

construed in accordance with the laws of the State of California, without regard
to the conflicts of law principles thereof.

         11.4     Assignment. This Agreement is personal in its character, and
neither Party shall assign its rights or obligations under this Agreement, in
whole or in part, without the prior written consent of the other Party; provided
that either Party may assign this Agreement (i) to any successor by merger or
sale of substantially all of the line of business to which this Agreement

made by any Party hereto of any of its rights under this Agreement unless such
waiver is in writing and is signed on behalf of such Party by its duly
authorized officer. Any such waiver shall constitute a waiver only with respect
to the specific matter described in such writing and shall in no way impair the
rights of the waiving Party in any other respect or at any other time. No change
or modification of this Agreement, or any of the provisions herein contained,

         11.6     Entire Agreement. This Agreement, together with the exhibits
and schedules hereto, embodies the entire understanding between the Parties and

with respect to the subject matter of this Agreement.

         11.7     Severability. If a court of competent jurisdiction declares

or other agency having jurisdiction over either Party deems any provision to be
contrary to any laws, then that provision shall be severed and the remainder of
