                             SCOPE OF COLLABORATION

         Section 2.01 Project Planning.

         (a)      Areas of Responsibility:

         Caliper shall have principal engineering responsibility for target
preparation automation and microfluidics and Affymetrix shall have principal
engineering responsibility for array and assay methods development, software
integration with respect to scanning, and system validation. Subject to the
foregoing, the initial Areas of Responsibility shall be set forth in the Work
Plan for any Project. Further specification of the initial Affymetrix Areas of
Responsibility and Caliper Areas of Responsibility shall be agreed as necessary
during the Term by the Parties. Prior to the commencement of any additional Area
of Responsibility, the Parties shall amend or supplement the Work Plan for a
Project in a mutually agreed to writing that specifies, among other things,
whether such Area of Responsibility is an Affymetrix Area of Responsibility or a
Caliper Area of Responsibility or both, and the related research objectives,
work plans and budgets.

         (b)      Work Plans:

         Subject to the next paragraph, the Parties shall execute a mutually
acceptable written Work Plan with respect to each distinct area of inquiry
(each, a "PROJECT") to be included in the Collaboration. Each such Work Plan
shall be binding, and shall deemed to be incorporated herein in its entirety. As
of the Effective Date, the initial Projects are the following (each of which
shall be documented with its own mutually acceptable Work Plan which shall be
attached to this Agreement when completed):

                  1.       Stacatto-based HTA system for gene expression
                           ("PROJECT 1");

                  2.       Sciclone-based automated target preparation system
                           for gene expression ("PROJECT 2");

                  3.       Sciclone-based automated target preparation system
                           for genotyping ("PROJECT 3");

                  4.       [ * ] ;

                  5.       [ * ] ; and

                  6.       [ * ] .

         The Work Plans for Project 1 and Project 2 are attached hereto as
Exhibits A and B, respectively. On or before March 31, 2004 (the "SECOND
COLLABORATION COMMENCEMENT DATE"), each Party shall notify the other Party in

<PAGE>

writing as to whether it wishes to proceed with the development of Work Plans
for any of Project 3 [ * ] . In the event that both Parties wish to proceed with
Work Plans for any of Project 3 [ * ] , the Parties shall proceed in good faith
to negotiate, prepare and document Work Plans for such Projects on or prior to
April 1, 2004 in the case of both Project 3 [ * ] . Notwithstanding the
foregoing, neither Party shall be obligated to proceed with Project 3 [ * ]
unless both Parties agree in writing to the Work Plans for such Project or
Projects pursuant to the terms of this Agreement.

         (c)      Conflict.

         In the event that the provisions of a Work Plan conflict with the
provisions of this Agreement with respect to a Project under such Work Plan, the
provisions of the Work Plan shall govern solely to the extent of any such
conflict and solely with respect to such Project.

         (d)      Content of Work Plan.

         Each Work Plan shall contain at least the following information and
terms with respect to such Project, where applicable or where different from the
terms set forth in this Agreement:

                  (i)      the identity of the Project Managers for the Project
         and/or the manner in which they will be selected;

                  (ii)     a description of the initial Areas of Responsibility
         for each Party (which shall include any joint Areas of Responsibility);

                  (iii)    a list of the Deliverables to be developed during the
         Project, including the functional requirements, technical
         documentation, specifications, protocols, standard operating procedures
         and branding requirements for each Developed Product;

                  (iv)     acceptance criteria for each Deliverable due during
         the Project, and procedures for the delivery, testing, acceptance and
         correction of any non-conformities for such Deliverables;

                  (v)      a schedule or timetable with a description of all
         Project milestones and/or Deliverable due dates;

                  (vi)     a description of any performance, status and
         operational reports to be generated during the Project;

                  (vii)    quality criteria for assessing the performance of the
         Parties during such Project including, but not limited to, performance
         criteria for milestones, classifications of the severity of errors or
         failures, and response processes for the correction of any such errors
         or failures;

<PAGE>

                  (viii)   a resources plan setting forth the resources and
         staffing required for such Project by each Party, and the extent, if
         any, to which one Party will reimburse the other Party for the
         personnel and other expenses incurred by such Party in connection with
         such Project;

                  (ix)     a plan setting forth [ * ] ; and

                  (x)      any other terms and conditions agreed upon by the
         Parties with respect to the Project.

         (e)      Termination of a Work Plan. Notwithstanding anything in this
Agreement to the contrary, either Party may elect at any time to cease
development work on any of Project 3 [ * ] pursuant to the approved applicable
Work Plan if (i) such Party reasonably determines, based on the written opinion
of independent patent counsel agreed to and retained by both Parties pursuant to
a joint defense agreement, that the product contemplated by such Project 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 product contemplated
by such Project in a manner reasonably acceptable to each Party) such that,
within a commercially reasonable time period thereafter, such independent patent
counsel is of the written opinion (as addressed to the Parties) that the product
contemplated by such Project no longer poses a substantial risk of infringing
third party Intellectual Property Rights. In addition to the foregoing, if at
any time a Party reasonably determines that the development of a product
contemplated by any of Project 3 [ * ] is no longer scientifically or
technically feasible, it shall promptly notify the other Party in writing
setting forth the basis for its determination in reasonable detail. The Steering
Committee shall promptly meet to discuss how to proceed with respect to such
Project taking into consideration the relative contributions and expectations of
the Parties with respect to the Project, but shall be under no obligation to
reach agreement with respect thereto. If the Parties are unable to agree on an
alternative course of action within thirty (30) calendar days (or such other
period as may be mutually agreed to by the Steering Committee) after the
consideration of such Project by the Steering Committee, the relevant Work Plan
shall be deemed to have been terminated.

         (f)      Duration of Initial Collaboration Period. The Parties agree
that the initial period of Collaboration (the "INITIAL COLLABORATION PERIOD")
shall begin on the Effective Date and end on the earlier of (i) the acceptance
by Affymetrix of Initial Developed Products from each of Project 1 and Project 2
pursuant to Section 4.02 of this Agreement, or (ii) the first anniversary of the
Effective Date. The Initial Collaboration Period may, however, be extended by
mutual written agreement of the Parties.

         (g)      Duration of the Second Collaboration Period. The Parties agree
that the second period of Collaboration (the "SECOND COLLABORATION PERIOD")
shall begin on the Second Collaboration Commencement Date and end on the earlier
of

<PAGE>

(i) the acceptance by Affymetrix of Developed Products from each of Project 3 [
* ] pursuant to Section 4.02 of this Agreement, or (ii) the first anniversary of
the Second Collaboration Commencement Date. The Second Collaboration Period may,
however, be extended by mutual written agreement of the Parties.

         Section 2.02 Steering Committee.

         (a)      Composition and Responsibilities.

         There shall be a committee consisting of two (2) persons (each of which
shall be at Affymetrix' Vice President level or above) appointed by Affymetrix
and two (2) persons (each of which shall be at Caliper's Vice President level or
above) appointed by Caliper (the "STEERING COMMITTEE"). Affymetrix' initial
designees shall be [ * ] , and Caliper's initial designees shall be [ * ] . The
Steering Committee shall establish procedures to govern the conduct of its
meetings including the election of co-chairmen (one from each Party), the
frequency of regular meetings, the calling of special meetings, advance notice
of meeting agendas and the keeping of minutes of its meetings. Action by the
Steering Committee shall require the affirmative vote or agreement of a majority
of the total number of members of the committee. The Steering Committee shall
meet at least once in any consecutive six-month period in person or via
teleconference. Either Party may call a meeting of the Steering Committee with
thirty (30) calendar days prior written notice to the other Party. Either Party
may, in its sole discretion by providing prior written notice to the other
Party, (x) replace its Steering Committee members, or (y) designate a substitute
for a committee member to participate in the event one of the Party's regular
committee members is unable to be present at a meeting. The Steering Committee
may, as it sees fit, create other committees (e.g., a research and development
committee, an intellectual property committee and a commercialization committee)
to which it may delegate responsibilities. Any such other committee shall have
an equal number of representatives from each Party (who need not be members of
the Steering Committee). The Steering Committee shall be responsible for the
strategic direction, coordination and oversight of all research and development
programs with respect to a Project within the Collaboration including without
limitation the following:

                  (i)      identification of the research goals and parameters
         with respect to each Area of Responsibility;

                  (ii)     specification of the research activities to be
         undertaken by each Party with respect to each Area of Responsibility;

                  (iii)    prioritization of research activities and allocation
         of resources among each Area of Responsibility (subject to the
         applicable Work Plan);

                  (iv)     monitoring the results of each Area of
         Responsibility;

<PAGE>

                  (v)      recommending to the Parties any material capital
         expenditures required in connection with any Area of Responsibility;

                  (vi)     recommending to the Parties budgeting and financial
         controls with respect to each Area of Responsibility;

                  (vii)    assessing the progress of each Work Plan in light of
         the goals set forth therein, including marketing and other
         commercialization efforts, and discussing and approving proposed
         amendments to each outstanding Work Plan as necessary;

                  (viii)   identifying future marketing and product
         opportunities that might be addressed through collaboration between the
         Parties; and

                  (ix)     such other responsibilities as may be assigned to it
         by the Parties.

                  (b)      Project Managers.

         The Steering Committee shall appoint one (1) person selected by
Affymetrix and one (1) person selected by Caliper to serve as Project managers
for each Project ("PROJECT MANAGER"). The Project Managers shall be reasonably
qualified to perform their responsibilities under the direction of the Steering
Committee and shall be reasonably acceptable to the other Party. The Project
Managers shall be responsible for the direction, coordination and execution of
the Project including but not limited to the following responsibilities (i)
administering and coordinating the technical aspects of each Project; (ii)
arranging meetings, visits and consultations relating to the technical aspects
of each Project; (iii) coordinating the submission of and testing of all

                  (c)      Disputes.

         Disputes that arise in any committee established by the Steering
Committee pursuant to Section 2.02(a) or that arise between Project Managers
with respect to a particular Project, and that such committee or Project
Managers, as the case may be, are unable to resolve themselves within twenty-one
(21) calendar days of formal written notice to the other Party that a dispute
exists (the "INITIAL DISPUTE RESOLUTION PERIOD") will be referred to the
Steering Committee. The Steering Committee shall attempt to resolve any disputes
between the Parties in good faith within twenty-one (21) calendar days after the
expiration of the Initial Dispute Resolution Period (the "STEERING COMMITTEE
DISPUTE RESOLUTION PERIOD"), or if such dispute arises in the Steering
Committee, within twenty-one (21) calendar days after formal written notice by
any of the Parties that a dispute exists. If the Steering Committee is unable to
resolve a dispute regarding any issue presented to it (or arising within the
Steering Committee) during the Steering Committee Dispute Resolution Period,
such dispute will be referred to

<PAGE>

designated officers of the Parties for good faith resolution, for a period of
thirty (30) calendar days following expiration of the Steering Committee Dispute
Resolution Period, pursuant to Section 10.02(a)(i) below. If such dispute is not
resolved by the end of such thirty (30) calendar day period, then either Party
shall be free to pursue any legal or equitable remedy available to it, in
accordance with Section 10.02(b) below.

         (d)      Mutual Support.

         The Parties will provide reasonably sufficient resources to support the
development effort for each Project including without limitation: (i) close
coordination with Project Managers, developers, testers and customers on a
worldwide basis; (ii) conference calls; (iii) travel for workshops, training,
laboratory setup, integration testing, and field trials; (iv) deployment of
modern state-of-the-art development processes, tools and methodologies; and (v)
compliance with all applicable labor law requirements. Unless otherwise agreed
to by the Parties in writing, each Party will bear its own costs in respect of
the activities specified in this Section 2.01(d) and shall be responsible for
managing its own resources; provided, however, that Caliper may condition its
agreement to participate in any marketing or sales activities at the request of
Affymetrix on Affymetrix' agreement to reimburse Caliper for any out-of-pocket
costs incurred by Caliper in connection with such activities.

         (e)      Records; Exchange of Information.

                  (i)      Records. During the Term of this Agreement, each
         Party will maintain complete and accurate scientific records of all
         work done and results achieved by that Party in the performance of
         their obligations pursuant to this Agreement ("COLLABORATION RECORDS").
         During the Term of this Agreement, each Party will grant the other
         Party reasonable access to that Party's Collaboration Records during
         ordinary business hours, the disclosure of which, without limiting the
         generality of Article 6 of this Agreement, shall be subject to the
         confidentiality restrictions provided therein.

                  (ii)     Reports. Periodically during the Term of this
         Agreement at the Steering Committee's request (but in any event at
         least quarterly with respect to each of Project 1 and Project 2), the
         Parties will provide the Steering Committee with written reports
         summarizing the progress of the work performed pursuant to this
         Agreement and any particular Project performed hereunder. Within thirty
         (30) calendar days after the termination or expiration of any Work Plan
         for a particular Project, each Party's Project Manager will provide a
         final written report to the Steering Committee summarizing such Party's
         activities and results during such Project.

         Section 2.03 Ownership of Intellectual Property.

         (a)      Notification. Each Party shall promptly notify the other of
any Inventions invented, discovered, generated, conceived or reduced to practice
by such Party.

         (b)      Sole Inventions. Unless otherwise provided in a Work Plan with
respect to a particular Project, any Inventions invented, discovered, generated,
conceived or reduced to practice solely by one or more employees or agents of a
Party (the "SOLE INVENTIONS") shall be the sole property of such Party, subject
to the licenses granted in Section 2.04 below.

         (c)      Joint Inventions.

                  (i)      Unless otherwise provided in a Work Plan with respect
         to a particular Project, the Parties shall jointly own, without
         obligation of accounting to each other, all Inventions that are
         invented, discovered, generated, conceived or reduced to practice by
         one or more employees or agents of a Party jointly with one or more
         employees or agents of the other Party (the "JOINT INVENTIONS").

                  (ii)     In furtherance of the foregoing, (A) Affymetrix
         hereby assigns and shall assign to Caliper an undivided joint ownership
         interest in and to the Joint Inventions, such interest to be without
         any obligation to account to Affymetrix with respect thereto and
         without any right to claim against Affymetrix for such accounting, and
         (B) Caliper hereby assigns and shall assign to Affymetrix an undivided
         joint ownership interest in and to the Joint Inventions, such interest
         to be without any obligation to account to Caliper with respect thereto
         and without any right to claim against Caliper for such accounting. For
         the avoidance of doubt, each of Affymetrix and Caliper shall have
         reserved for itself an undivided joint ownership interest in and to the
         Joint Inventions.

                  (iii)    Each Party shall execute and do all things reasonably
         necessary to vest such joint rights, title and interest in, to and
         under the Joint Inventions equally in both Parties. The Parties shall
         reasonably cooperate with one another in connection with the
         prosecution and defense of Patents with respect to Joint Inventions,
         and except as provided below, shall share equally in any costs and
         expenses incurred in connection therewith. If at any time one Party
         declines to fund the prosecution or maintenance of a Patent pursued by
         the other Party with respect to a Joint Invention, the declining Party
         shall immediately, and hereby does and will assign all of its right,
         title and interest in and to such Joint Invention to the other Party,
         and shall provide such non-financial support as the other Party may
         reasonably request in the prosecution of such Patent.

<PAGE>

                  (iv)     Prior to filing with any patent authority any
         application for any Patent the subject matter of which is any Joint
         Invention (each, a "JOINT PATENT"), the Parties shall mutually agree on
         (A) which of the two parties will be primarily responsible for the
         filing, prosecution, defense and maintenance, before any such patent
         authorities, of such Joint Patent (such Party, the "PROSECUTION PARTY")
         and (B) the law firm which shall be used for the filing, prosecution,
         defense and maintenance of such Joint Patent, provided that unless the
         Parties otherwise agree in writing, Caliper shall be the Prosecution
         Party for any Joint Patent relating to liquid handling or microfluidics
         and Affymetrix shall be the Prosecution Party for any Joint Patent
         relating to arrays, reagents for target preparation, genotyping,
         resequencing, gene expression, transcript and exon analysis or other
         genomic system protocols, and scanning. The Party which is not the
         Prosecution Party shall have the right to review and comment on the
         filing, prosecution and defense by the Prosecution Party of the Joint
         Patents. If the Prosecution Party determines in its sole discretion to
         not file, prosecute, defend or maintain any Patent within the Joint
         Patents in any country, then the Prosecution Party shall provide the
         other Party with thirty (30) calendar days prior written notice of such
         determination and shall provide the other Party with the right and
         opportunity to file, prosecute, defend and maintain such Patent.
         Subject to Section 2.03(c)(iii) above, all costs and expenses
         associated with the filing, prosecution, defense and maintenance,
         before any such patent authorities, of the Joint Patents shall be
         shared equally by the Parties.

         Section 2.04 Licenses.

         (a)      Limited Cross License to Perform the Collaboration. During the
Term of this Agreement and subject to the terms and conditions of this

         paid-up, royalty-free, worldwide, non-exclusive, transferable and
         sublicensable (directly or indirectly through multiple tiers) license
         under all of Caliper's Intellectual Property Rights to make, have made,
         use, sell, have sold, offer to sell, have offered for sale, import and
         have imported Caliper's Sole Inventions, for the life of any such
         Intellectual Property Rights.

<PAGE>

                  (ii)     Subject to any restrictions set forth in a Work Plan,
         Affymetrix hereby grants to Caliper a perpetual, irrevocable, fully
         paid-up, royalty-free, worldwide, non-exclusive, transferable and
         sublicensable (directly or indirectly through multiple tiers) license

         any such Intellectual Property Rights.

         (c)      No Implied License to Background Technology. For the avoidance
of doubt, except as expressly set forth in this Agreement, each Party retains
sole ownership and control of its Background Technology and no license is
conveyed, by implication, estoppel or otherwise, under the Background Technology
of either Party.

         (d)      Patent Enforcement.

                  (i)      Notification. If either Party learns of material
         infringement, unauthorized use, misappropriation or ownership claim
         (any of the foregoing, an "INFRINGEMENT") by a third party with respect
         to any of the other Party's Inventions, such Party shall promptly
         notify the other Party and shall provide such other Party with
         available evidence of such Infringement.

                  (ii)     Right to Bring Suit. Caliper shall have the exclusive
         right, but not the obligation, to institute Patent or other
         Intellectual Property Rights Infringement actions against third parties

         based on any Affymetrix Technology.

                  (iii)    Expenses. The costs and expenses of any such action
         (including fees of attorneys and other professionals) shall be borne by
         the Party instituting the action, or, if the Parties elect to cooperate
         in instituting and maintaining such action, such costs and expenses
         shall be borne by the Parties in such proportions as they may agree in
         writing.

                  (iv)     Standing and Cooperation. Each Party shall execute
         all reasonably necessary and proper documents, take such actions as
         shall be appropriate (at the other Party's reasonable expense) to allow
         the other Party to institute and prosecute such infringement actions
         and shall otherwise reasonably cooperate in the institution and
         prosecution of such actions (including, without limitation, consenting
         to being named as a nominal party thereto).

<PAGE>

                  (v)      Proceeds. Any award paid by third parties as a result
         of such an infringement action (whether by way of settlement or
         otherwise) shall be applied first to reimburse both Parties for all
         costs and expenses incurred by the Parties with respect to such action
         on a pro rata basis and, if after such reimbursement any funds shall
         remain from such award, they shall be allocated as follows: (i) if
         Caliper has instituted and maintained such action alone, Caliper shall
         be entitled to retain such remaining funds; (ii) if Affymetrix has
         instituted and maintained such action alone, Affymetrix shall be
         entitled to retain such remaining funds; or (iii) if the Parties have
         cooperated in instituting and maintaining such action, the Parties
         shall allocate such remaining funds between themselves in the same
         proportion as they have agreed to bear the expenses of instituting and
         maintaining such action.

         Upon Caliper's determination that it has completed a Project and that
the resulting Deliverable conforms with the applicable specifications and/or
documentation agreed upon by Affymetrix and set forth in or created under the
applicable Work Plan for such Deliverable ("SPECIFICATIONS"), Caliper shall
promptly deliver to Affymetrix for evaluation one prototype of such Deliverable
(a "PROTOTYPE") and a copy of the complete instructions and operational
documentation for the Prototype. Upon the acceptance of such Prototype by
Affymetrix pursuant to section 4.02, Affymetrix shall, as reasonably as
practicable, return such Prototype to Caliper for modification into an Initial
Developed Product, and, upon shipment to Affymetrix of such Initial Developed
Product, Caliper shall invoice Affymetrix and Affymetrix shall pay Caliper in
accordance with the terms of this Agreement. For purposes of clarification, the
shipment of such Initial Developed Product shall count towards Affymetrix'
Minimum Purchase Requirement.

<PAGE>

receipt of the Prototype in which to evaluate the Prototype in order to
determine whether or not it conforms to the Specifications and is commercially
satisfactory. In the event Affymetrix reasonably determines in the course of
such evaluation that the Prototype does not conform to the Specifications, or is
not commercially satisfactory, Affymetrix shall so notify Caliper in writing
specifying in reasonable detail the nature of the deficiencies discovered by
Affymetrix in the course of its evaluation. Caliper shall have a period of
thirty (30) calendar days (or such other period as may be mutually agreed to by
the Steering Committee) thereafter in which to use its best efforts to correct
any such deficiencies specified by Affymetrix and submit an appropriately
revised version of the Prototype to Affymetrix for further evaluation (a
"CALIPER DEFICIENCY CORRECTION PERIOD"). Affymetrix shall then have successive
thirty (30) calendar day (or such other period as may be mutually agreed to by
the Steering Committee) reevaluation periods (each, an "AFFYMETRIX REEVALUATION
PERIOD"), each such Affymetrix Reevaluation Period being followed by a Caliper
Deficiency Correction Period of thirty (30) calendar days (or such other period
as may be mutually agreed to by the Steering Committee), until the earlier of
such time as either (i) Affymetrix notifies Caliper in writing that Affymetrix'
evaluation of the latest version of the Prototype submitted by Caliper has not
revealed any nonconformities with the Specifications and that Affymetrix has
determined that the Prototype is commercially satisfactory ("ACCEPTANCE DATE"),
(ii) after Affymetrix has notified Caliper in writing that Caliper's third
attempt to correct the deficiencies specified by Affymetrix is not accepted,
Affymetrix also notifies Caliper in writing that it elects to terminate the
efforts to develop the applicable Developed Product, or (iii) after Caliper has
notified Affymetrix in writing of Caliper's conclusion that a fourth attempt by
Caliper is not reasonably likely to correct the deficiencies specified by
Affymetrix and is not reasonably likely to be accepted by Affymetrix, Caliper
also notifies Affymetrix in writing that it elects to terminate the efforts to
develop the applicable Developed Product (either of the events described in the
foregoing clause (ii) or clause (iii) being referred to herein as "PROJECT
TERMINATION").

         (b)      On the Acceptance Date of the Initial Developed Product from
Project 1, the provisions of Article 5 shall become effective with respect to
the Initial Developed Product from Project 1 (the "PROJECT 1 ACCEPTANCE DATE"),
on the Acceptance Date of the Initial Developed Product from Project 2, the
provisions of Article 5 shall become effective with respect to the Initial
Developed Product from Project 2 (the "PROJECT 2 ACCEPTANCE DATE"), and on the
Acceptance Date of the Initial Developed Product from Project 3, the provisions
of Article 5 shall become effective with respect to the Initial Developed
Product from Project 3. The earlier to occur of the Project 1 Acceptance Date
and the Project 2 Acceptance Date shall be referred to herein as the "INITIAL
ACCEPTANCE DATE" and the later to occur of the Project 1 Acceptance Date and the
Project 2 Acceptance Date shall be referred to herein as the "FINAL ACCEPTANCE
DATE". For purposes of this Agreement, "PROJECT ACCEPTANCE DATE" shall mean,
when used in reference to a particular Project, the Acceptance Date of the

applicable to the providing of Repair Services. Caliper's invoice shall contain
the following:

                  (i)      Affymetrix' Purchase Order number for the Repair
         Services;

                  (ii)     a detailed description of the Repair Services

replacement Initial Developed Products and shall comply with the requirements
set forth in Exhibit I.

         (g)      Products Beyond Repair. Caliper shall promptly notify
Affymetrix of returned Initial Developed Products which are found by Caliper to

reparable, which determination will be made as soon as commercially reasonable
after Caliper's receipt of the Initial Developed Product.

         (h)      Repairs by Third Parties. Nothing in this Agreement shall be
construed as giving Caliper an exclusive privilege to repair any Initial
Developed Products covered under this Agreement; provided, however, that the
Parties acknowledge that the repair of any Initial Developed Products during the
Warranty Period by any third party who is not authorized by Caliper to perform
service work may have the effect of voiding Caliper's warranty obligations with
respect to such Initial Developed Product.

         Section 5.19 Discontinuation (Service & Spares).

         Following expiration of the Term, Caliper shall make available to
Affymetrix replacement parts and Repair Services for the Initial Developed

         Caliper undertakes to ensure that it and any of its material component
manufacturers and suppliers shall maintain ISO 9001:2000 certification in effect
throughout the Term, and Caliper's failure to ensure that any such party
maintains ISO 9001:2000 certification shall constitute a material breach by
Caliper of its obligations hereunder.

         In the event that Caliper or any of Caliper's material component
manufacturers and suppliers receive any notice of major non-conformance to ISO

<PAGE>
from the ISO registrars, Caliper shall immediately advise Affymetrix and

notice as reasonably possible. Affymetrix reserves the right to reevaluate and
submit to acceptance testing as specified above in Article 4 any Initial
Developed Product affected by a

Developed Products, including appropriate technical and marketing materials, in
a timely and cooperative manner consistent with the schedule set forth on
Exhibit L and in any event not less favorable than the manner in which each
Party provides its own marketing and sales personnel with similar information.
Each Party will bear the full cost for the development and production of the
technical and marketing materials relating to its own product(s) and both
Parties agree to label such technical and marketing materials relating to the
interrelationship between the Initial Developed Products and Affymetrix products
with appropriate branding and trademarks of each other's Party as mutually
agreed by the Parties pursuant to this Agreement; in the event of co-branded
literature relating equally to both

<PAGE>

Party's products, the Parties shall share the cost for development and
production of such materials as determined by the Steering Committee.

         Section 6.01 Confidential Information.

         Each Party shall retain the other Party's Confidential Information in
the strictest confidence (on a need to know basis) and shall not disclose such
Confidential Information to any person without the other Party's express written
consent, other than to an employee, agent or professional advisor of the
receiving Party under a duty of confidentiality not less than that required of
the Parties herein. Notwithstanding anything to the contrary in this Agreement,
the obligation to maintain the confidentiality of Confidential Information shall
not apply to the extent that the receiving Party is required to disclose such
Confidential Information pursuant to law or legally enforceable order of a court
or judicial body; provided that the receiving Party provides notice to the
disclosing Party as soon as possible to enable the disclosing Party to seek a
protective order or an injunction.

         Section 6.02 Restricted Use.

         With respect to the Confidential Information of the other Party, each

this Agreement and as expressly permitted by this Agreement;

         (b)      not to make copies of or store Confidential Information or any
part thereof except as expressly permitted by this Agreement;

         (c)      to reproduce and maintain on any copies of any Confidential
Information such proprietary legends or notices (whether of disclosing Party or
a third party) as are contained in or on the original or as the disclosing Party
may otherwise reasonably request;

         (d)      not to modify or prepare derivative works from, or decompile,
disassemble or reverse engineer, or sell, publish, make available, compile,
display or transfer any Confidential Information; and

         (e)      to treat the terms and conditions of this Agreement as
Confidential Information; provided, however, that each Party may disclose the
terms and conditions of this Agreement: (i) in confidence, to its accountants,
banks and financing sources and their advisors; (ii) in connection with the
enforcement of this Agreement or rights under this Agreement; (iii) in
confidence, in connection

third party contractors who have a need to know, solely in connection with their
provision of services to such Party; (vi) as required by applicable securities
laws (including but not limited to the filing of this Agreement (or any
amendment or supplement hereto) as an exhibit to a document filed with the
Securities and Exchange Commission) or the rules of any stock exchange on which
securities of such Party are traded or any other applicable regulatory rule or
regulation or governmental agency directive; provided, however, that prior to
making any such disclosure, the receiving Party shall provide notice to the
other Party regarding the nature and extent of the disclosure to enable the
other Party to seek to obtain confidential treatment, to the extent available,
for such Confidential Information; and provided further, however, that with
respect to the filing of this Agreement (or any amendment or supplement hereto)
as an exhibit to a document filed with the Securities and Exchange Commission,
the Parties shall agree in advance as to the proper scope of confidential
treatment to be sought with respect thereto; or (vii) as mutually agreed upon by
the Parties.

         Section 6.03 Publicity

         The Parties anticipate that upon execution of this Agreement, each
Party will issue a press release, or may issue a joint press release, regarding
the collaboration established pursuant to this Agreement. Notwithstanding the
foregoing, neither Party shall issue any press release relating to the
announcement of the execution of this Agreement by the Parties without the prior
written approval of the other Party, which approval shall not be unreasonably
withheld, or delayed for longer than three (3) business days.

         Upon the expiration or termination of this Agreement, the duties and
obligations of the Parties hereunder under any Work Plan for a particular
Project shall likewise expire or terminate, unless (i) such Work Plan by its

the Parties mutually agree that such Work Plan shall survive such expiration or
termination of this Agreement in certain respects.

         Section 8.06 Survival.

         Section 9.01 Indemnification.

         (a)      Caliper hereby agrees to indemnify, defend and hold harmless
Affymetrix and its affiliates, agents, directors, officers and employees (the
"AFFYMETRIX INDEMNITEES") from and against any and all liabilities, costs, fees,
expenses and/or losses, including without limitation reasonable legal costs,
expenses and attorneys' fees for outside counsel (collectively, "LOSSES")
resulting from any third party claims, suits, actions or demands arising out of
(i) any of Caliper's representations and warranties set forth in this Agreement
being untrue in any material respect when made; (ii) any material breach or
material default by Caliper of its covenants and obligations under this
Agreement; and/or (iii) a claim by such third party that any Caliper Technology,
or any portion thereof, when used in accordance with the terms and conditions of
this Agreement, infringes on

<PAGE>

or constitutes a misappropriation of any Intellectual Property Rights of a third
party.

         (b)      Affymetrix hereby agrees to indemnify, defend and hold
harmless Caliper and its Affiliates, agents, directors, officers and employees
(the "CALIPER INDEMNITEES") from and against any and all Losses resulting from
any third party claims, suits, actions or demands arising out of (i) any of
Affymetrix' representations and warranties set forth in this Agreement being
untrue in any material respect when made; (ii) any material breach or material
default by Affymetrix of its covenants and obligations under this Agreement;
and/or (iii) a claim by such third party that any Affymetrix Technology, or any
portion thereof, when used in accordance with the terms and conditions of this
Agreement, infringes on or constitutes a misappropriation of any Intellectual
Property Rights of a third party.

         Section 9.02 Indemnification Procedures.

         To be eligible to be so indemnified as described in Section 9.01, the
indemnified Party shall provide the indemnifying Party with prompt notice of any

nature and amount of any such Loss) giving rise to the indemnification
obligation pursuant to Section 9.01 and the exclusive ability to defend such
claims, suits, actions or demands (with the reasonable cooperation of
indemnified Party). The indemnified Party shall have the right to retain its own
counsel, at its own expense, if representation of the counsel of the
indemnifying Party would be inappropriate due to actual or potential differing
interests between the Parties. Neither Party shall settle or consent to the
entry of any judgment with respect to any claim for Loss for which
indemnification is sought, without the prior written consent of the other Party
(not to be unreasonably withheld).

CONTRACT OR TORT OR BASED ON A WARRANTY OR OTHERWISE) FOR LOSS OF PROFITS,

CONSEQUENTIAL DAMAGES INCURRED BY THE OTHER PARTY OR ANY THIRD PARTY, EVEN IF
THE PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

         Section 10.02 Dispute Resolution.

         (a)      Informal Resolution.

                  (i)      The Parties recognize that disputes as to certain
         matters may from time to time arise during the term of this Agreement
         which relate to either Party's rights and or obligations. It is the
         objective of the Parties to establish procedures to facilitate the
         resolution of disputes arising under this Agreement in an expedient
         manner by mutual cooperation and without resort to litigation, if
         possible. To accomplish this objective, the Parties agree to follow the
         procedures set forth in Section 2.02(b) above and this Section 10.02 if
         and when an issue or dispute arises under this Agreement.

                  (ii)     If the Steering Committee is unable to resolve any
         issue or dispute arising within its authority (or referred to it
         pursuant to Section 2.02(b) above) under the terms of this Agreement
         within thirty (30) calendar days thereof, or upon any other dispute or
         issue regarding a Party's rights or obligations under this Agreement,
         any Party may, by written notice to the other, have such dispute or
         issue referred to their respective chief executive officers, for
         attempted resolution by good faith negotiations.

                  (iii)    Upon such referral of an issue or dispute for
         resolution, such designated officers shall meet promptly thereafter and
         shall use good faith efforts to attempt to resolve such dispute or
         issue.

         (b)      Formal Resolution.

                  (i)      Any unresolved dispute or issue shall be resolved by
         binding arbitration under 35 U.S.C. 294. The Parties agree that under
         35 U.S.C. 294(c), in the event a patent which is the subject of an
         arbitration award is subsequently determined to be invalid or
         unenforceable by a court or governmental body of competent jurisdiction
         from which no appeal can or has been taken such arbitration award may
         be modified by any court of competent jurisdiction upon application by
         a party to the arbitration. Whenever a Party shall decide to institute
         arbitration proceedings, it shall give written notice to that effect to
         the other Party. The Party giving such notice shall refrain from
         instituting the arbitration proceedings for a period of ten (10)
         calendar days following such notice to allow the Parties to attempt to
         resolve the dispute between themselves. If the Parties are still unable
         to resolve the dispute, the Party giving notice may institute the
         arbitration proceeding before JAMS or its successor pursuant to the
         United States Arbitration Act 9 U.S.C. Section 1 et seq. Arbitration
         shall be held in the San Francisco Bay Area of California. The
         arbitration shall be conducted in accordance with the provisions of
         JAMS Comprehensive Arbitration Rules and Procedures before a single
         arbitrator

<PAGE>

         mutually chosen by the Parties, but if the Parties have not agreed upon
         a single arbitrator within fifteen (15) calendar days after notice of
         the institution of the arbitration, then a single arbitrator shall be
         chosen under JAMS rules from neutrals who have experience trying
         complex commercial dispute cases. All arbitrator(s) eligible to conduct
         the arbitration must undertake in writing as a condition of service to
         render their opinion(s) promptly after the final arbitration hearing
         and to provide a reasoned written opinion setting forth the findings of
         fact and conclusions of law. No arbitrator shall have the power to
         award punitive damages or any award of multiple damages under this
         Agreement and such awards are expressly prohibited. Judgment on the
         award of the arbitrator(s) may be entered in any court in the County of
         Santa Clara, California. Except to the extent entry of judgment and any
         subsequent enforcement may require disclosure, or except as required by
         law, all matters relating to the arbitration, including the award,
         shall be held in confidence by the Parties.

                  (ii)     This Agreement shall be governed, construed and
         enforced in accordance with the laws of the State of California,
         without reference to conflict of laws principles. Each of the Parties
         hereto consents to submit to the exclusive personal jurisdiction of the
         U.S. District Court for the Northern District of California and to any
         state court located in such district in the event that any dispute
         arises out of this Agreement, agrees that such Party will not attempt
         to deny or defeat such personal jurisdiction by motion or other request
         for leave from any such court, and agrees that such Party will not
         bring any action relating to this Agreement in any court other than the
         U.S. District Court for the Northern District of California or a state
         court located in such district.

         (c)      Notwithstanding anything to the contrary contained in this
Agreement, the Parties may seek an injunction or injunctions to prevent breaches
of this Agreement and to enforce specifically the terms thereof in any court of
the United States or any state thereof having jurisdiction, this being in
addition to any other remedy to which they may be entitled at law or equity.

         Section 10.03 Non-solicitation.

         The Parties acknowledge and agree that each Party's employees and
consultants are a valuable asset and are difficult to replace. Accordingly, each
Party agrees that, during the Term and for a period of [ * ] thereafter, it will
not knowingly offer employment as an employee, independent contractor, or
consultant to the other Party's employees, independent contractors, or
consultants. The Parties agree that the foregoing shall not be deemed to
prohibit either Party from making a general, public solicitation of employment
in the ordinary course of such Party's business, provided that such solicitation
is not directed specifically to employees of the other Party.

<PAGE>

         Section 10.04 Assignment.

         Except as otherwise expressly provided in this Agreement, neither this
Agreement nor any rights under this Agreement may be assigned or otherwise
transferred by either Party, in whole or in part, whether voluntarily or by
operation of law, including by way of sale of assets, merger or consolidation or
other similar transaction, without the prior written consent of the other Party,
which consent will not be unreasonably withheld; provided, however, that (i)
Affymetrix may, without Caliper's consent, assign this Agreement or any of its
rights or obligations hereunder to (a) an affiliate of Affymetrix or (b) a
person, other than an Affymetrix Disqualified Assignee, that is a successor to
substantially all of the assets of Affymetrix (whether by way of sale of assets,
merger or consolidation or other similar transaction), in each case who executes
a written agreement of assumption by which it agrees to be bound hereby,
provided that Affymetrix shall not be relieved of its obligations hereunder in
connection with any such assignment, and (ii) Caliper may, without Affymetrix'
consent, assign this Agreement or any of its rights or obligations hereunder to
a person, other than a Caliper Disqualified Assignee, that is a successor to
substantially all of the assets of Caliper (whether by way of sale of assets,
merger or consolidation or other similar transaction) who executes a written
agreement of assumption by which it agrees to be bound hereby, provided that
Caliper shall not be relieved of its obligations hereunder in connection with
any such assignment. Subject to the foregoing, this Agreement will be binding
upon and will inure to the benefit of the Parties and their respective
successors and assigns; and provided further, however, that in connection with
any assignment by Affymetrix of this Agreement or any of its rights or
obligations hereunder without Caliper's consent, Caliper shall have the right to
terminate any Work Plan for any Project with respect to which the Project
Acceptance Date shall not have occurred on or prior to the date of such
assignment (for purposes of clarification, Caliper shall, under such
circumstances, have no right to terminate any of its obligations under this
Agreement relating to the manufacture and sale of any Initial Developed Product,
under Article 5 or otherwise, with respect to which the Acceptance Date shall
have occurred on or prior to the date of such assignment). For purposes of this
Section 10.04, (i) an "AFFYMETRIX DISQUALIFIED ASSIGNEE" shall be any person or
entity that [ * ] , and (ii) a "CALIPER DISQUALIFIED ASSIGNEE" shall be any
person or entity that [ * ] .

         Section 10.05 Independent Contractors.

         The relationship of the Parties established by this Agreement is that
of independent contractors, and nothing contained in this Agreement shall be
construed or implied to give either Party the power to direct or control the
day-to-day activities of the other, nor shall any Party have the right or
authority to assume, create or incur any third party liability or obligation of
any kind, express or implied, against or in the name of or on behalf of another
except as expressly set forth in this Agreement.

<PAGE>

         Section 10.06 Severability.

         In the event that any provision of this Agreement conflicts with
governing law or if any provision is held to be null, void or otherwise
ineffective or invalid by a court of competent jurisdiction, (a) such provision
shall be deemed to be restated to reflect as nearly as possible the original
intentions of the Parties in accordance with applicable law, and (b) the
remaining terms, provisions, covenants and restrictions of this Agreement shall
remain in full force and effect. This Agreement has been negotiated by the
Parties and their respective counsel and will be interpreted fairly in
accordance with its terms and without any strict construction in favor of or
against either Party.

         Section 10.07 Entire Agreement.

         This Agreement is an integrated document and all attachments hereto and
incorporated herein constitute the entire, final, complete and exclusive
agreement between the Parties and supersede all previous agreements, intentions,
or representations, oral or written, relating to this Agreement. This Agreement
may not be modified or amended except in a writing signed by a duly authorized
representative of each Party. Both Parties acknowledge having read the terms and
conditions set forth in this Agreement and all attachments hereto, understand
all terms and conditions, and agree to be bound hereby.

         Section 10.08 No Waiver.

         The failure of either Party to enforce at any time any of the
provisions of this Agreement shall not be deemed to be a waiver of the right of
either Party thereafter to enforce any such provisions.

         Section 10.09 Force Majeure.

         If either Party is prevented from performing any of its obligations
hereunder due to strike, fire, flood, governmental act or order or restriction,
or act of God, or any other reason where failure to perform is beyond the
control and not caused by the negligence of the non-performing Party (a "FORCE
MAJEURE EVENT"), such non-performing Party shall not be liable for breach of
this Agreement with respect to such non-performance to the extent any such
non-performance is due to a Force Majeure Event. Such non-performance shall be
excused until the termination of such Force Majeure Event, provided that the
non-performing Party gives immediate written notice to the other Party of the
Force Majeure Event. Such non-performing Party shall exercise all reasonable
efforts to eliminate the Force Majeure Event and to resume performance of its
affected obligations as soon as practicable. Neither Caliper nor Affymetrix
shall be entitled to rely on a Force Majeure Event to relieve it from an
obligation to pay money (including any interest for delayed payment) that would
otherwise be due and payable under this Agreement (save to the extent that
payment of the same cannot be made by reason of bank strike or similar
occurrence).

         Section 10.10 Notices.

         Any notice required or permitted under the terms of this Agreement or
required by law must be in writing and must be (a) delivered in person; (b) sent
by first class registered mail, or air mail, as appropriate; or (c) sent by

EXHIBIT H
ZYMARK SCICLONE PRODUCT FACTORY WARRANTY

Zymark warrants your Zymark manufactured equipment, including hardware,
software, and firmware, and the Zymark purchased controller (if applicable),
against defects in material and workmanship for a period of one (1) year from
the date of shipment.

WHAT IS INCLUDED

-        On site service is provided during normal business hours, your local
     time from 8AM through 5PM, excluding holidays. A Zymark representative will
     make his/her best effort to be on site within three business days.

-        Unlimited emergency on site repair services, parts, and software
     corrections that affect original functional design specifications, and
     their associated labor and travel expenses.

-        Unlimited access to Zymark's Technical Support Center during the
     warranty period, which provides troubleshooting, repair instruction,
     service dispatching, replacement part information, and shipment.

-        One pre-scheduled on site Preventive Maintenance and Diagnostic
     Servicing (PM) performed by a Zymark Field Service Engineer. A PM visit
     includes the replacement of Limited-Life parts exposed to fluidics, such as
     syringes, valves, seals, and fittings. The Zymark Field Service Engineer
     will perform a comprehensive analysis and testing to confirm the equipment
     is left operating to factory specifications.

-        Scheduling of the PM within the warranty period is flexible and
     determined by the customer after notification by the Zymark Field Service
     Engineer. The servicing is typically scheduled six months after the
     equipment installation, but equipment usage rate and availability may cause
     the date to vary. A completed Zymark Field Service Report provides thorough
     documentation of all maintenance and service work performed by the Zymark
     Field Service Engineer during the on site visit. (Exception: Documentation
     is not provided when Zymark provides service via telephone, fax, or modem.)

-        Limited-Life parts are covered for thirty (30) days after installation
     and are replaced once during the PM. See description of Limited Life Parts
     later in this warranty.

-        Cosmetic surfaces are warranted for thirty (30) days from date of
     installation.

Customers MUST use the Zymark-purchased controller. If customers fail to use
Zymark's controller, field service charges incurred during the workstation
installation process will be charged at Zymark's current rates. These charges
include round-trip travel and on site installation time, transportation
expenses, and per them living expenses.

Any defects covered by this warranty shall be corrected by replacing or
repairing the affected item, at Zymark's option. Parts replaced during the
warranty period will be covered for the remaining term of the original warranty,
or for thirty (30) days from time of replacement, whichever is longer. Such
replacement parts may, at Zymark's option, be new or remanufactured. All parts
removed from war ranted equipment become the property of Zymark Corporation.

Zymark reserves the right to satisfy its warranty obligations in full by
refunding the purchase price minus any service, validation, or travel charges of
any defective product.

CUSTOMER RESPONSIBILITIES

-        The equipment must be used under normal installation and application
     conditions as described in the User's Manual.

-        The equipment must be maintained as described in the User's Manual.

-        Reasonable precautions should be taken to keep caustic atmospheric
     conditions, chemical spills, and biological and radioactive contamination
     from rendering the equipment irreparable, which would void this warranty.
     See the Hazardous Limitation Statement for further details.

-       Zymark Automation Certified Disposables are required for proper
     operation of all applicable products.

-       The customer is responsible for making the equipment available for a PM
     during the warranty period. Zymark will not be held liable for a missed PM
     due to restricted access to the equipment during the coverage period.

-        When Zymark provides telephone, fax, or modem support, the customer is
     responsible for completing any necessary documentation of the service.

<PAGE>

-        If the customer maintains a change control/validation logbook as a
     permanent record, then he/she is responsible for entering all service
     documentation into this log.

-        Customers must perform the appropriate level of revalidation required
     as a result of maintenance or service provided.

-        Data back up is the responsibility of the customer. Zymark will not be
     held liable for loss of data due to failure of the PC (controller) hardware
     or software.

-        Customer will make the equipment available for emergency and
     preventative maintenance servicing upon arrival of a Zymark Field Service
     Engineer.

EXCLUSIONS

ANY ALTERATION OF THE HARDWARE OR SOFTWARE ON ZYMARK PRODUCTS COVERED UNDER THIS
WARRANTY, THAT ARE NOT PERFORMED BY ZYMARK CORPORATION OR AN APPROVED ZYMARK
VENDOR, WILL VOID THIS WARRANTY.

-        Product that has been subject to misuse, accident, negligence or
     improper transportation, handling, installation, storage, use, maintenance,
     or application is not covered under this warranty.

-        The Sciclone 384-channel low volume head is warranted for one (1) year
     or 750,000 aspirate or dispense movements, whichever comes first.

-        The Sciclone 100nL head is warranted for one (1) year or 600,000
     aspirate or dispense movements, whichever comes first.

-        Zymark Automated Certified Disposables are required for proper
     operation. Repair services required for inaccurate operation, accuracy, or
     precision due to the use of non-Zymark Automated Certified Disposables will
     void this warranty and be invoiced at Zymark's current field service rates.

-        This warranty is intended to cover equipment manufactured by Zymark.
     Equipment purchased from other vendors is not covered by this warranty.

-        Zymark will provide service for Zymark supported software and hardware
     platforms only. A Zymark representative has the right to remove any
     unsupported software from the controller when troubleshooting to eliminate
     any possible software conflicts it may have on Zymark equipment. Service
     due to unsupported software loaded on the controller will be invoiced at
     Zymark's current field service rates.

-        Limited-Life parts are covered for thirty (30) days after installation
     and are replaced once during the PM. Beyond this replacement, these parts
     are available at current list prices and are designed for replacement by
     the customer. See the description of Limited-Life Parts below.

-        Damage to Limited-Life parts caused by insufficient maintenance or
     cleaning practices, or abnormal applications are not covered under this
     contract. If these situations are diagnosed, charges are at current list
     prices for parts and current service rate structure for labor and travel.

-        Application and chemistry support is not included.

-        Software releases that contain new product features and functionality
     are offered for sale by Zymark and are not included under this program.

-        This warranty applies only to the original users and delivery
     locations. It is not transferable to other users or locations without
     pre-approval from Zymark.

LIMITED-LIFE PARTS

Limited-Life Parts are any parts that are exposed to solvents, reagents, or
samples. Such parts include, but are not limited to: syringes, valves, seals,
and fittings. These parts are warranted to be functional at the time of
installation and are covered for thirty (30) days after installation. Limited
Life Parts are routinely replaced by Zymark Field Service Engineers during a PM
visit or during Zymark Repair Depot servicing. Otherwise, these parts are
available from Zymark at current list prices and are designed for replacement by
the customer.

REPAIR AUTHORIZATION

In servicing situations requiring the return of equipment to Zymark, equipment
must be returned to Hopkinton, MA, USA, or a facility designated by Zymark. The
customer shall prepay charges for equipment returned to Zymark, with Zymark
paying for equivalent return shipment to the customer.

HAZARDOUS LIMITATION STATEMENT

AT NO TIME WILL ZYMARK PERSONNEL PERFORM SERVICE ON UNSAFE EQUIPMENT, PERFORM
SERVICE IN UNSAFE ENVIRONMENTS, OR DECONTAMINATE EQUIPMENT TO MAKE IT SAFE.

ZYMARK IS NOT LICENSED TO ACCEPT PRODUCTS THAT HAVE BEEN EXPOSED TO RADIOACTIVE
MATERIALS.

Prior to the performance of any service work, Zymark personnel will evaluate the
condition of the equipment and the environment in which the equipment is
located. After evaluation and discussion with the customer, Zymark commits to
the following:

-        When the environment and equipment are determined to be free of
     chemical, radioactive and bio-hazardous materials by Zymark personnel,
     servicing will be performed.

-        When the equipment and/or the environment are determined to be
     hazardous by Zymark personnel, Zymark reserves the right to refuse
     servicing the equipment. One of two situations will then occur:

     1)   The customer will decontaminate the equipment and/or the environment
          in which the equipment is located to the satisfaction of Zymark
          personnel, prior to Zymark servicing.

     2)   The customer decides not to decontaminate the equipment and/or the
          environment, and takes responsibility to service the equipment
          themselves through on site, verbal instruction from Zymark personnel.
