OBJECTIVE:

The objective of this cooperative research project is to develop and implement a
high speed mass spectrophotometer based genotyping system for livestock. This
requires a system to utilize primers for single nucleotide polymorphism (SNP) in
livestock.

APPROACH:

A mass spectrophotometer based high speed genotyping system is required for use
of SNP's to genotype livestock populations. To efficiently use expressed
sequence tags (EST) sequence data in livestock and link this information with
the human genome database, we must be able to genotype SNP's in livestock
populations. Preliminary studies with the Sequenom DNA MassArray analytical
system have demonstrated this system can be used effectively to genotype SNP's
in livestock. This system will be implemented and upgraded to develop markers
for SNP's and map these markers on the ARS linkage maps.

STATEMENT OF MUTUAL INTEREST:

Both parties are actively engaged in independent research projects to identify
and implement efficient SNP genotyping systems. This project combines Sequenom's
expertise and technology relating to their DNA MassArray Basic System Plus and
ARS's expertise and technology relating to SNP marker development to develop and
implement a high speed SNP genotyping system. The parties agree that meeting the
objectives of this project will strengthen and enhance ongoing research within
the scope of this agreement.

THE COOPERATOR AGREES TO:

1.   Work closely with ARS in planning and providing engineering and systems
support for conducting the research outlined below.

2.   Conduct at ARS facilities and elsewhere as appropriate, engineering and
systems support research to upgrade the DNA MassArray Analytical System for use
in developing markers for SNP's..... activities include:

a.   Provide for the use during this project of a DNA MassArray Basic System
Plus incorporating the following components: a High-speed Bruker/SEQUENOM Array
Mass Spectrometer; a Spectrojet Nanoliter Dispenser; a SEQUENOM BioMASS
lnformatics Workstation and use of appropriate software; Beckman Multimek
Instrument with SEQUENOM Magnetic Lifters. Provide hardware and software
upgrades to the system as they become available.

b.   Provide SEQUENOM 96 D SpectroChipTM , reagents, and the magnetic beads
required in sample preparation for 200,000 elements (excluding the reagents
provided for by ARS and

outlined below). An element is defined as a sample pad on SEQUENOM's
SpectroChipTM (Patent US 5,605,798).

c.   Assist in developing markers to run on this "system."

d.   Assist in integrating DNA MassArray data with the ARS livestock database.

ARS AGREES TO:

1.   Work closely with the cooperator in planning and conducting the research
outlined above.

2.   Conduct research on the following aspects of the project:

a.   Develop primers to amplify specific regions of DNA (Primers and PCR
reagents will be provided by ARS).

b.   Identify SNP markers within the amplified fragments.

c.   Synthesize probe primers that can be used with the DNA MassArray Basic
System to genotype the SNPs (reagents to be provided by ARS include primers,
neucleotides, enzymes, biotinylated primers).

d.   Utilize SNP genotypic data to place the markers on the linkage map.

MUTUAL AGREEMENTS:

1.   The estimated budget, Form ARS-454, is hereby incorporated into the
agreement. The awarding agency will reimburse the Cooperator for costs related
to salaries, material, supplies in the amount of $436,000, and will contribute
in-house resources in the amount of $574,900. As evidence of the Cooperator's
contribution to this project the Cooperator will provide in-house resources in
the amount of $312,187.50.

2.   Payments to the Cooperator will be made quarterly via Electronic Funds
Transfer (EFT), upon submission of a properly executed invoice. See ARS-452,
Part 15 (Attached). Reimbursement for the use of the DNA MassArray Basic System
will be made after delivery of the system and evidence that ARS can produce
acceptable results; reimbursement of expenses associated with the BioMass Probe
reaction units ($150,000/100,000 elements) will be based on quantity used; and
the monthly maintenance fee will be reimbursed on a quarterly basis.

3.   The use of the DNA MassArray Basic System Plus and Spectrochip (System)
will be solely used for purposes of livestock SNP analysis. The Cooperator shall

1.  By signing and submitting this form, the prospective primary participant is
providing the certification set on the reverse side in accordance with these
instructions.

2.  The inability of a person to provide the certification required below will

prospective participant shall submit an explanation of why cannot provide the
certification set out on this form. The certification or explanation will be
considered connection with the department or agency's determination whether to

which reliance was placed when the department or agency determined to enter into
this transaction. If it is later determined that the prospective primary
participant knowingly rendered an erroneous certification, in addition to other
remedies available to the Federal Government, the department or agency may
terminate this transaction for cause or default.

4.  The prospective primary participant shall provide immediate written notice
to the department or agency to whom this proposal is submitted if at any time
the prospective primary participant learns that its certification was erroneous

                        Instructions for Certification
                        ------------------------------

1.   By signing and submitting this form, the grantee is providing the
     certification set out on pages 1 and 2

2.   The certification set out on pages 1 and 2 is a material representation of
fact upon which reliance is placed when the agency awards the grant. If it is
later determined that the grantee knowingly rendered a false certification, or
otherwise violates the requirements of the Drug-Free Workplace Act, the agency,
in addition to any other remedies available to the Federal Government, may take
action authorized under the Drug-Free Workplace Act.

3.   Workplaces under grants, for grantees other than individuals, need not be
identified on the certification. If known, they may be identified in the grant
application. If the grantee does not identify the workplaces as the time of
application, or upon award, if there is no application, the grantee must keep
the identity of the workplace(s) on file in its office and make the information
available for Federal inspection. Failure to identify all known workplaces
constitutes a violation of the grantee's drug-free workplace requirements.

4.   Workplace identifications must include the actual address of buildings (or
parts of buildings) or other sites where work under the grant takes place.
Categorical descriptions may be used (e.g., all vehicles of a mass transit
authority or State highway department while in operation, State employees in
each local unemployment office, performers in concert halls or radio studios).

5.   If the workplace identified to the agency changes during the performance of
the grant, the grantee shall inform the agency of the change(s), if it
previously identified the workplaces in question (see paragraph 3).

6.   Definitions of terms in the Nonprocurement Suspension and Debarment common
rule and Drug-Free Workplace common rule apply to this certification. Grantees'
attention is called, in particular, to the following definitions from these
rules:

"Controlled" substance means a controlled substance in Schedules I through V of

                     Certification/Disclosure Requirements
                              Related to Lobbying

________________________________________________________________________________

Section 319 of Public Law 101-121 (31 U.S.C.), signed into law on October 23,
1989, imposes new prohibitions and requirements for disclosure and certification
related to lobbying on recipients of Federal contracts, grants, cooperative
agreements, and loans. Certain provisions of the law also apply to Federal
commitments for loan guarantees and insurances; however, it provides exemptions
for Indian tribes and tribal organizations.

Effective December 23, 1989, current and prospective recipients (and their
subtier contractors and/or subgrantees) will be prohibited from using Federal
funds, other than profits from a Federal contract, for lobbying Congress or any
Federal agency in connection with the award of a particular contract, grant,
cooperative agreement or loan. In addition, for each award action in excess of
$100,000 (or $150,000 for loans) on or after December 23, 1989, the law requires
recipients and their subtier contractors and/or subgrantees to: (1) certify that
they have neither used nor will use any appropriated funds for payment to
lobbyists, (2) disclose the name, address, payment details, and purpose of any
agreements ,with lobbyists whom recipients or their subtier contractors or
subgrantees will pay with profits or nonappropriated funds on or after December
23, 1989; and (3) file quarterly updates about the use of lobbyists if material
changes occur in their use. The law establishes civil penalties for
noncompliance.

If you are a current recipient of funding or have an application, proposal or
bid pending as of December 23, 1989, the law will have the following immediate
consequences for you:

-    You are prohibited from using appropriated funds (other than profits from
Federal contracts) on or after December 23, 1989, for lobbying Congress or any
Federal agency in connection with a particular contract, grant, cooperative
agreement, or loan;

-    you are required to execute the attached certification at the time of
submission of an application or before any action in excess of $100,000 is
awarded; and

-    you will be required to complete the lobbying disclosure form if the
disclosure requirements apply to you.

Regulations implementing Section 319 of Public Law 101 - 121 have been published
as an Interim Final Rule by the Office of Management and Budget as Part III of
the February 26, 1990 Federal Register (pages 6736-6746).

                                 INSTRUCTIONS

GENERAL

This form is for use in submitting INTERIM and FINAL invention reports to the
Contracting Officer and for use in the prompt notification of the award of
subcontracts containing a "Patent Rights" clause. If the form does not afford
sufficient space, multiple forms may be used or plain sheets of paper with
proper identification of information by Item may be attached.

An INTERIM report is due at least every 12 months from the date of contract
award and shall include (a) a listing of "Subject Inventions" during the
reporting period, (b) a certification of compliance with required invention
identification and disclosure procedures together with a certification of
reporting of all "Subject Inventions." and (c) any required information not
previously reported on subcontracts awarded during the reporting period and
containing a "Patent Rights" clause.

A FINAL report is due within 6 months if contractor is a small business firm of
domestic nonprofit organization and within 3 months for all others after
completion of the contract work and shall include (a) a listing of all "Subject
Inventions" required by the contract to be reported, and (b) any required
information not previously reported on subcontracts awarded during the course of
or under the contract and containing a "Patent Rights" clause.

While the form may be used for simultaneously reporting inventions and
subcontracts, it may also be used for reporting, promptly after award,
subcontracts containing a "Patent Rights" clause.

Dates shall be entered where indicated in certain Items on this form and shall
be entered in four or six digit numbers in the order of year and month (YYMM) or
year, month and day (YYMMDD). Example: April 1981 should be entered as 8104 and
April 15, 1981 should be entered as 810415.

                    contract (DAR 20-203).

Item 2d. thru 5c.   Self-explanatory.

Item 5f, ii and iii. The name and address of the employer of each inventor not
employed by the contractor subcontractor is needed inasmuch as the Government's
rights in a reported invention may not be determined solely by the terms of the
"Patent Rights" clause in the contract. Example (1): If an invention is made by
a Government employee assigned to work with a contractor, the Government rights
in such an invention will be determined under Executive Order 10096. Example
(2): I f an invention is made under a contract by joint inventors and one of the
inventors is a Government employee, the Government's rights in such an
inventor's interest in the invention will also be determined under Executive
Order 10096, except where the contractor is a small business or nonprofit
organization, in which case the provisions of Section 202(c) of P.L. 96-517 will
apply.

Item 5g, 1.  Self-explanatory.

Item 5g, ii. Self-explanatory with the exception that the contractor or
subcontractor shall indicate, if known at the time of this report, whether
application will be filed under either the Patent Cooperation Treaty (PCT) or

country.
