NOTES TO FINANCIAL STATEMENTS

Interim Financial Statements

In the opinion of management, all adjustments consisting only of normal
recurring accruals necessary for a fair presentation of such amounts have been
included. The results of operations for the quarter are not necessarily
indicative of results for the year.

Inventories

Inventories are stated at the lower of cost or market.

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS

Summary Analysis

In this first quarter of fiscal year 1998, Diagnon realized net income of $986.

On June 11, 1997, the Company was granted United States Department of
Agriculture approval to sell and distribute the oral/IV version of its equine
immunoglobulin product, Lyphomune(R). Previously, Lyphomune(R) could only be
administered orally. The highly purified equine IgG is used for treatment for
Failure of Passive Transfer (FPT) of immunity in newborn foals. During the first
twenty-four hours postpartum foals showing symptoms of FPT can be, under normal
circumstances, administered IgG orally; however, after twenty-four hours
postpartum, the foals, generally, must be treated using intravenous (IV)
methods.

To complement the Company's distribution agreement with The Butler Co., Diagnon
has entered into Lyphomune(R) distribution agreements with Milburn
Distributions, Inc. and Burns Veterinary Supply, Inc. as additional distributors
of Lyphomune(R) to veterinary practitioners and with Jeffers Veterinary Supply,
Inc. to distribute the product to over-the-counter retail customers. To this
date, Diagnon has only sold Lyphomune(R) to veterinarians and the Jeffers
agreement represents increased market exposure for the product.

The following developments occurred after the end of the quarter and therefore
are not reflected in the results of operations of the quarter:

o        On September 30, 1997, the Company's subsidiary, BIOQUAL, Inc., was
         awarded a National Cancer Institute (NCI) Small Business Innovation
         Research (SBIR) Grant titled "Nonhuman Primate Model for Helicobacter
         Pylori Infection". This six month grant totals $100,000.

o        Also on September 30, 1997, BIOQUAL was awarded a National Institute of
         Diabetes and Digestive and Kidney Diseases SBIR Grant titled
         "Identification of Helicobacter pylori Protective Antigens". The six
         month grant totals $99,673.

o        On October 1, 1997, BIOQUAL was awarded and began work on the sole
         source renewal of the NCI contract "Facility for Preparing and Housing
         Virus Infected Mice, Genetically Manipulated Mice and Chimeric Mice".
         This four year contract totals $3,161,223.

Results of Operations

For the three months of operations ended August 31, 1997 (the Company's first
quarter), Contract Revenues increased by 2.0% compared to the first quarter of
fiscal year 1997 (FY97) while Product Sales were relatively the same. Contract
Operating Expenses increased 2.1% compared to the first quarter of FY97
primarily due to increased contract activity. Cost of Goods Sold increased to
$16,478 from $620 in the first quarter of FY97. This increase was primarily due
to the expensing, from inventory, of 147 units of Lyphomune(R) used in a sales
promotion. Research and Development (R&D) expenses increased to $117,850
compared to $81,733 in the first quarter of FY97. This increase was primarily
due to increased costs associated with the Company's ongoing Helicobacter pylori
research program. General and Administrative (G&A) Expenses decreased 3.3%
compared to the first quarter of FY97 primarily due to a temporary reduction of
staff compensation during this quarter. Total Operating Expenses increased 3.3%
due to the above.

Operating Income decreased 68.9% compared to the prior year as Total Operating
Expenses increased at a greater rate than Total Revenues and Sales. The
operating expense increase was primarily due to the increases in Cost of Goods
Sold and R&D expenses mentioned above.

For this quarter, Diagnon had Interest Expense of $12,121 compared to Interest
Expense of $11,815 in the prior year.

Liquidity and Capital Resources

Assets

The changes in Cash and Cash Equivalents are detailed in the Statements of
Consolidated Cash Flows on page 4. Total Assets increased $62,576 as compared to
May 31, 1997. This increase is primarily attributable to 1) an increase in Fixed
Assets, net of Accumulated Depreciation and Amortization of $110,889, reflecting
fixed asset purchases of $181,266 (mainly nonhuman primate enclosures) offset by
depreciation and amortization of $70,377 during this quarter, and 2) Prepaid
Expenses increased $70,703 primarily due to the prepayment of $17,400 in life
insurance premiums, $18,000 in business insurance premiums, a $25,000 salary
advance to the President during the negotiation of his employment agreement, and
the prepayment of $7,000 in real estate and personal property taxes.

The increase above is partially offset by a decrease in Accounts Receivable of
$66,237 consisting primarily of 1) a decrease of $82,929 to Unbilled Accounts
Receivable reflecting a decrease in prior year unbilled direct costs of $125,440
that were billed in June 1997 and an increase in reimbursable indirect rate
variances of $42,511 during this quarter, 2) an increase of $42,860 to Trade
Receivables, and 3) a $26,168 decrease to Other Accounts Receivable due to the
collection of a prior year receivable from the Medical Center Dr. facility
landlord. Other Noncurrent Assets decreased $54,000 due to the completion of a
nonhuman primate housing unit order from the previous fiscal year.

<PAGE>


Liabilities

In the first three months of operations, Total Liabilities increased $61,590 as
compared to May 31, 1997. This increase is primarily attributable to an increase
to Borrowings Under Line-of-Credit of $256,449 reflecting the increase in Fixed
Assets and Prepaid Expenses stated above.

The above increase is partially offset by 1) a decrease in Accounts Payable of
$31,900, 2) a decrease in Accrued Compensation and Related Costs of $121,619
reflecting a shorter accrual period this quarter when compared to the prior year
end, and 3) payments totalling $30,005 on capital leases reducing Long-Term
Debt.

The Company believes it has sufficient cash and financing sources to provide for
its ongoing operations and the Company continues to believe that the impact of
inflation, or the absence of it, will have no significant effect on its
operations.

PART II.  Other Information

Item 1.  LEGAL PROCEEDINGS

On September 3, 1997 Lourdes Weisgerber, a former employee, filed a Complaint in
The United States District Court for the District of Maryland (Southern
Division) Case No. PJM 972970 alleging that BIOQUAL, Inc. violated her
employment rights under the American With Disabilities Act. This allegation was
previously reported as an administrative law matter within the Equal Employment
Opportunity Commission (EEOC) and the Montgomery County Human Relations
Commission. The joint investigation conducted by the Montgomery County Human
Relations Commission found no discrimination. Ms. Weisgerber asked for and
received a Notice of Right to Sue upon the dismissal of the administrative
complaint by Montgomery County and the EEOC. The Plaintiff has sued for backpay,
emotional distress, pain and suffering, punitive damages, and attorneys' fees
and costs. While the Company intends to defend this action vigorously and
believes that it will not have a material effect on its financial condition, it
can not give any assurance of the results of this pending litigation.

SECTION H - SPECIAL CONTRACT REQUIREMENTS

ARTICLE H.l. REIMBURSEMENT OF COSTS FOR INDEPENDENT RESEARCH AND DEVELOPMENT
PROJECTS

The primary purpose of the Public Health Service (PHS) is to support and advance
independent research within the scientific community. This support is provided
in the form of contracts and grants totaling approximately 7 billion dollars
annually. PHS has established effective, time tested and well recognized
procedures for stimulating and supporting this independent research by selecting
from multitudes of applications those research projects most worthy of support
within the constraints of its appropriations. The reimbursement through the
indirect cost mechanism of independent research and development costs not
incidental to product improvement would circumvent this competitive process.

To ensure that all research and development projects receive similar and equal
consideration, all organizations may compete for direct funding of independent
research and development projects they consider worthy of support by submitting
those projects to the appropriate Public Health Service grant office for review.
Since these projects may be submitted for direct funding, the Contractor agrees
that no costs for any independent research and development project, including
all applicable indirect costs, will be claimed under this contract.

ARTICLE H.2. HUMAN SUBJECTS

It is hereby understood and agreed that research involving human subjects shall
not be conducted under this contract, and that no material developed, modified,
or delivered by or to the Government under this contract, or any subsequent
modification of such material, shall be used by the Contractor or made available
by the Contractor for use by anyone other than the Government, for experimental
or therapeutic use involving humans without the prior written approval of the
Contracting Officer.

ARTICLE H.3. INTRODUCTION OF RODENTS AND RODENT PRODUCTS

No rodent or rodent product shall be delivered into the NIH, NCI environment
(NIH) directly, or through collaborative research or holding facilities under
contract to NCI except by permit. Direct shipments to NIH from a commercial
colony will be considered exempt. Non-exempt sources must be approved by permit
issued through the National Center for Research Resources (NCRR). The permit
must be obtained by the Contractor prior to the shipment to NIH of the rodents
and/or rodent products. The Contractor must be sure that this permit exists and
is current before transferring rodents or rodent products into the NIH, NCI
environment. Refusal or negligence to do so will be considered a material breach
of contract and may be treated as any other such material breach. Applications
for permits should be submitted not less than 30 days prior to shipping date to:
NIH Veterinary Resources Branch (VRP), National Center for Research Resources
(NCRR), Scientific Services Branch, Laboratory Sciences Section, Building 28A,
Room 11 1, 28 LIBRARY DR MSC 5210, BETHESDA MD 20892-5210, (301)496-4463.

ARTICLE H.4. ANIMAL WELFARE ASSURANCE

The Contractor shall obtain, prior to the start of any work under this contract,
an approved Animal Welfare Assurance from the Office of Protection from Research
Risks (OPRR), Office of the Director, NIH, as required by Section 1-43-30 of the
Public Health Service Policy on Humane Care and Use of Laboratory Animals. The
Contractor shall maintain such assurance for the duration of this contract, and
any subcontractors performing work under this contract involving the use of
animals shall also obtain and maintain an approved Animal Welfare Assurance.

ARTICLE H.5. OPTION PROVISION

Unless the Government exercises its option pursuant to the Option Clause set
forth in ARTICLE I.3., the contract will consist only of the work required in
accordance with the Statement of Work, as defined in Sections C and F, for the
Base Year (Year 1) of the contract. Pursuant to FAR 52.217-9, set forth in
ARTICLE 1.3. of this contract, the Government may, by unilateral contract
modification, require the Contractor to perform the work required in accordance
with the Statement of Work, as defined in Sections C and F, for Options 1

exercises these options, notice must be given at least 60 days prior to the
expiration date of this contract, and the estimated cost plus fixed fee of the

PHS 352.223-70 SAFETY AND HEALTH (DEVIATION) (AUGUST 1997)

(a)   To help ensure the protection of the life and health of all persons, and
      to help prevent damage to property, the Contractor shall comply with all
      Federal, State and local laws and regulations applicable to the work being
      performed under this contract. These laws are implemented and/or enforced
      by the Environmental Protection Agency, Occupational Safety and Health
      Administration and other agencies at the Federal, State and local levels
      (Federal, State and local regulatory/enforcement agencies).

(b)   Further, the Contractor shall take or cause to be taken additional safety
      measures as the Contracting Officer in conjunction with the project or
      other appropriate officer, determines to be reasonably necessary. If
      compliance with these additional safety measures results in an increase or
      decrease in the cost or time required for performance of any part of work
      under this contract, an equitable adjustment will be made in accordance
      with the applicable "Changes" Clause set forth in this contract.

(c)   The Contractor shall maintain an accurate record of, and promptly report
      to the Contracting Officer, all accidents or incidents resulting in the
      exposure of persons to toxic substances, hazardous materials or hazardous
      operations; the injury or death of any person; and/or damage to property
      incidental to work performed under the contract and all violations for
      which the Contractor has been cited by any Federal, State or local
      regulatory/enforcement agency.  The report shall include a copy of the
      notice of violation and the findings of any inquiry or inspection, and an
      analysis addressing the impact these violations may have on the work
      remaining to be performed.  The report shall also state the required
      action(s), if any, to be taken to correct any violation(s) noted by the
      Federal, State or local regulatory/enforcement agency and the time frame
      allowed by the agency to accomplish the necessary corrective action.

(d)   If the Contractor fails or refuses to comply promptly with the Federal,
      State or local Regulatory/enforcement agency's directive(s) regarding any
      violation(s) and prescribed corrective action(s), the Contracting Officer
      may issue an order stopping all or part of the work until satisfactory
      corrective action (as approved by the Federal, State or local
      regulatory/enforcement agencies) has been taken and documented to the
      Contracting Officer. No part of the time lost due to any stop work order
      shall be subject to a claim for extension of time or costs or damages by
      the Contractor.

(e)   The Contractor shall insert the substance of this clause in each
      subcontract involving toxic substances, hazardous materials, or
      operations. Compliance with the provisions of this clause by
      subcontractors will be the responsibility of the Contractor.

      INTRODUCTION OF RODENTS AND RODENT PRODUCTS

A.    Purpose. This Policy Manual establishes procedures designed to prevent the
      introduction of infected rodents and rodent products into the National
      Institutes of Health which could: (1) adversely affect the health of
      rodents used in research; (2) directly or indirectly interfere with
      research; or (3) pose a health hazard to personnel.

B.    Background. The conduct of a vigorous research program necessitates the
      movement of animals and their tissues from animal colony to animal colony
      and between laboratories. This creates the possibility of introducing
      agents that are pathogenic to either animals or humans. Examples of the
      latter include the lymphocytic choriomeningitis (LCM) virus and the
      hantaviruses, which can have serious implications for human health.
      Hantaviruses infect wild rodents and have been detected in laboratory rats
      in Europe and Asia; humans in contact with infected animals can become ill
      and occasionally die.

      Federal regulations pertaining to the movement of laboratory rodents or
      their products relate mainly to organisms causing diseases in humans or
      domestic poultry or livestock. Thus, it is important for the NIH to
      supplement these regulations with policies that address concerns relating
      to protection of its intramural animal colonies and scientific and support
      staff in contact with animals or animal products.

C.    Applicability. The policies and procedures in this chapter apply when
      introducing into any National Institutes of Health (NIH) facility rodents
      and rodent products that originate from sources other than those approved
      by the Veterinary Resources Program (VRP), National Center for Research
      Resources (NCRR). This policy also applies to facilities of other Agencies
      on NIH property.

D.    Definitions.

      1.     Animal Program Director (APD). The individual (usually a
             veterinarian) who receives delegated program authority from the
             Director or Scientific Director for all activities involving
             animals in the ICD.

      2.     Approved Source. A source of rodents or rodent products which has a
             contract established with, and maintained by, the NCRR. VRP or a
             comparable contract with other programs within the NIH to supply
             genetically-defined, specific pathogen-free

      INTRODUCTION OF RODENTS AND RODENT PRODUCTS

      1.     Animals from nondomestic sources:

             j.    The principal investigator must complete and submit the
                   application to his/her APD. The APD will obtain the
                   concurrence of the facility veterinarian and then forward it
                   to the Rodent Import Officer. In most cases, importation from
                   nondomestic sources will require quarantine and health
                   assessment at the VRP Rodent and Rabbit Quarantine Unit
                   located at the NIH Animal Center near Poolesville, Maryland.
                   If animals are being brought to NIH for tissue harvesting
                   only, quarantine may be minimal, but tissues must be
                   harvested at the Poolesville Quarantine Facility.

             k.    If the animals are destined for an NIH animal facility, the
                   APD will obtain additional health status information to be
                   attached to the application. The facility veterinarian must
                   specify on the application the animal health requirements to
                   be met, in addition to negative test results for LCM and
                   ectromelia viruses, prior to release from quarantine.

             c.    Animals will be quarantined at the VRP Rodent and Rabbit
                   Quarantine Unit located at the NIH Animal Center near
                   Poolesville, Maryland or an alternative site approved by the
                   Rodent Import Officer.  The Rodent Import Officer will
                   maintain a list of recognized rodent agents developed with
                   the Animal Program Directors and approved by the Animal
                   Research Advisory and Safety Committee which must be excluded

      INTRODUCTION OF RODENTS AND RODENT PRODUCTS

             b.    1)      If animals are destined for a laboratory for holding
                           less than 12 hours, where no contact with other
                           animals is planned and no materials from the animals
                           will be inoculated into rodents or used in materials
                           destined for introduction into rodents, then the
                           application can be approved by the APD.  A permit
                           number will be obtained from the Rodent Import
                           Officer and the APD will provide the Rodent Import
                           Officer with a copy of the application and the
                           permit.

                   2)      If animals are destined for a laboratory for holding
                           more than 12 hours, where no contact with other
                           animals is planned and no material from those animals
                           will be introduced into rodents or used in materials
                           destined for introduction into rodents, the ICD
                           Animal Care and Use Committee (ACUC) must approve the
                           holding of the animals in the laboratory. The
                           application can then be evaluated by the APD and
                           approved if appropriate.

                   3)      If animals are destined for an animal facility or
                           will come into contact with other rodents, or if
                           materials derived from the imported rodents will be
                           inoculated into rodents or used in materials destined
                           for introduction into rodents, the APD will obtain
                           additional health status information and attach it to
                           the application. Concurrence of the facility
                           veterinarian must also be obtained. Prior to
                           forwarding the application to the Rodent Import
                           Officer, the facility veterinarian must specify on
                           the application the animal health requirements
                           necessary for entry into the designated animal
                           facility, including the mandatory negative test
                           results for LCM and ectromelia viruses.

             C.    The Rodent Import Officer, in consultation with the facility
                   veterinarian and principal investigator, will: (1) designate
                   the quarantine location; and (2) specify the criteria for
                   release from quarantine. If the VRP Rodent and Rabbit
                   Quarantine Unit, located at the NIH Animal Center is used,
                   the Rodent Import Officer will: (1) conduct testing and
                   review results; (2) provide results to the facility
                   veterinarian; and (3) release animals as appropriate. Non-VRP
                   quarantine locations must provide the NIH Rodent Import
                   Officer with documentation that release criteria have been
                   met prior to release of the animals.

      INTRODUCTION OF RODENTS AND RODENT PRODUCTS

H.    Procedure for Introduction of Rodent Products. (See Appendix 1 for
      schematic of procedures.) The introduction of rodent products into NIH
      laboratories or animal facilities also requires the submission and
      approval of an application, NIH Form 2369- 1, or receipt of permission
      from the principal investigator's laboratory or branch chief, as described
      below:

      1.     Procedure for Introduction of Rodent Products into an NIH Animal
             Facility.

             The principal investigator must complete and submit the application
             through the APD, or his/her designee, to the facility veterinarian.
             This includes the purchase of rodent products on BPAS. Unless a
             recent Mouse Antibody Production (MAP)/Rat Antibody Production
             (RAP)/Hamster Antibody Production (HAP) test result is available,
             cells must be maintained frozen until tested and determined to be
             free of LCM and ectromelia viruses, at a minimum, before
             introduction into an NIH animal facility. The facility veterinarian
             will issue a permit listing the agents that the product must be
             free of, including the agents listed above. The permit number will
             be obtained from the Rodent Import Officer. The facility
             veterinarian will provide a copy of the application and permit to
             the Rodent Import Officer. Alternatively, a permit may be issued if
             the product will be inoculated into animals within an appropriate
             quarantine facility such as the VRP Rodent and Rabbit Quarantine
             Unit at the NIH Animal Center near Poolesville, Maryland.

             The principal investigator will not introduce the animal product
             into an NIH animal facility unless the facility veterinarian
             receives the test results and approves the introduction.

      2.     Procedure for Introduction of Rodent Products into an NIH
             Laboratory.

             If rodent products will not be introduced into, or come in contact
             with live animals, a permit is not required. The Quarantine Permit
             Service Office (QPSO), Occupational Safety and Health Branch,
             Division of Safety, should be consulted to determine if a USDA
             permit is required (for reasons stated below). It is the
             responsibility of the principal investigator's laboratory or branch
             chief to assess the zoonotic potential of the material and
             determine if testing is required prior to importation and use.
             Assistance in making this determination is available from the NIH
             Biosafety Officer, Occupational Safety and Health Branch Division
             of Safety (496-2960).

      INTRODUCTION OF RODENTS AND RODENT PRODUCTS

      3.     Alternative Methods for Introduction of Non-living Rodent Products.

             As an alternative to conducting MAP/RAP/HAP testing of nonliving
             rodent products coming to the NIH from an unapproved or nondomestic
             source, the laboratory or branch chief and/or the APD or his/her
             designee, may approve the sterilization of the products. It is the
             responsibility of the individuals designated above to ensure that
             the method of sterilization is appropriate and adequate/effective
             prior to introduction of the material into NIH facilities. In the
             case of materials being introduced into laboratories, the
             Laboratory Chief is the approving official; in the case of an
             animal facility, the facility veterinarian is the approving
             official.

I.    Quarantine Permit Service Office (QPSO), Occupational Safety and Health
      Branch, Division of Safety.

      Several agencies of the United States Government regulate and require
      permits for the importation, shipment, or exportation of animals, animal
      products, or etiologic agents or vectors of human or animal diseases. The
      Quarantine Permit Service Office (QPSO) of the NIH Occupational Safety and
      Health Branch, Division of Safety, will provide investigators with
      assistance and appropriate application forms necessary to import, export,
      or transport regulated materials or animals.

      1.     The United States Department of Agriculture (USDA) Animal and Plant
             Health Inspection Service (APHIS) has statutory authority to
             regulate the importation of any animal-derived material or
             biological material that has been in contact with material of
             animal origin. Thus, USDA permits are required for the importation
             of monoclonal antibodies, hybridoma cell lines, cell cultures, and
             other biologic materials that have been in contact with material of
             animal origin, such as fetal bovine serum.

      INTRODUCTION OF RODENTS AND RODENT PRODUCTS

      2.     The Public Health Service (PHS) is responsible for regulations
             involving the importation into the United States or distribution
             after importation, of any etiologic agent or any arthropod or other
             animal host or vector of human disease (see NIH Manual Chapter
             1340-1, Permits for Import or Export of Biological Materials). A
             PHS permit must be obtained for importation and/or distribution of
             these materials. The Chief, QPSO, or his/her designee, is
             authorized to issue PHS import permits.

      3.     The United States Fish and Wildlife Service (USFWS), United States
             Department of Interior, is responsible for regulations involving
             the prevention and control of wildlife diseases, and the
             importation of wildlife or products derived from threatened or
             endangered wildlife species. Permits for designated port exemptions
             are issued through the QPSO.

      4.     Finally, the QPSO must be notified, and a USDA permit obtained, if
             transgenic rodents, carrying receptors which enable those rodents
             to develop productive infection with human pathogens, are imported
             into the United States or transported within the United States by
             NIH investigators (496-3353).

J.    Additional Information.

      For further information on this policy, contact the Rodent Import Officer,
      Veterinary Resources Program, NCRR, on 402-2799 or the applicable ICD
      Animal Program Director. Additional copies of this policy may be obtained
      by submitting the request to Printing and Reproduction Branch (P&RB), DSS,
      Stonestreet, Room 115.

      For additional information on the importation or transportation of any
      etiologic agent or host or vector of human or animal diseases, or the
      importation of wildlife, contact the Quarantine Permit Service Office,
      Division of Safety (496-3353).

commercialization license may be required. Recipient agrees to comply with all
Federal rules and regulations applicable to the Research Project and the
handling of the Research Material.

      2.(a) Are Research Materials of human origin?  ___ Yes   ___ No

      2.(b) If Yes in 2.(a), were Research Materials collected according to 45
CFR 46 "Protection of Human Subjects?"  ___ Yes  ___ No.   Please provide

      3. This Research Material will be used by recipient's investigator solely
in connection with the following research project ('Research Project") described
with specificity as follows (use an attachment page if necessary:
________________________________________________________________________________
________________________________________________________________________________

      4. In all oral presentations or written publications concerning the
Research Project, Recipient will acknowledge Provider's contribution of this
Research Material unless requested otherwise. To the extent permitted by law,
Recipient agrees to treat in confidence, for a period of three (3) years from
the date of its disclosure, any of Provider's written information about this
Research Material that is stamped "CONFIDENTIAL," except for information that
was previously known to recipient or that is or becomes publicly available or
which is disclosed to Recipient without a confidentiality obligation. Recipient
may publish or otherwise publicly disclose the results of the Research Project,
but if Provider has given CONFIDENTIAL information to Recipient such public
disclosure may be made only after Provider has had thirty (30) days to review
the proposed disclosure, except when a shortened time period under court order
or the Freedom of Information Act pertains.

      5. This Research Material represents a significant investment on the part
of Provider, and is considered proprietary to Provider. Recipient's investigator
therefore agrees to retain control over this Research Material, and further
agrees not to transfer the Research Material to other people not under her or
his direct supervision without advance written approval of Provider. Provider
reserves the right to distribute the Research Material to others and to use it
for its own purposes. When the Research Project is completed, or three (3) years
have elapsed, whichever occurs first, the Research Material will be destroyed by
Recipient or otherwise disposed of as mutually agreed by Provider and Recipient.

      6.     This Research Material is provided as a service to the research
community. IT IS BEING SUPPLIED TO RECIPIENT WITH NO WARRANTIES, EXPRESS OR
IMPLIED, INCLUDING ANY

WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.  Provider makes
no representations that the use of the Research Material will not infringe any
patent or proprietary rights of third parties.

      7. When Provider is the NIH/ADAMHA: Recipient shall retain title to any
patent or other intellectual property rights in inventions made by its employees
in the course of the Research Project Recipient agrees not to claim, infer, or
imply Governmental endorsement of the Research Project, the institution or
personnel conducting the Research Project or any resulting commercial
product(s). Recipient agrees to hold the United States Government harmless and
to indemnify the Government for all liabilities, demands, damages, expenses and
losses arising out of Recipient's use for any purpose of the Research Material.

      8. When Recipient is the NIH/ADAMHA: The NIH/ADAMHA shall retain tit e to
any patent or other intellectual property rights in, inventories made by its
employees in the course of the Research Project. The NIH/ADAMHA are not
authorized to promise rights in advance for inventions developed through this
Research Project, except under a Cooperative Research and Development Agreement
("CRADA") pursuant to the Federal Technology Transfer Act of 1986. Except as may
be accorded through Paragraph 9., below, Provider acquires no intellectual
property rights under this MTA, but may apply for license rights to any
patentable invention that might result from this Research Project. It is the
intention of NIH/ADAMHA that Provider not be liable to NIH/ADAMHA for any claims
or damages arising from NIH/ADAMHA's use of the Research Material; however, no
indemnification is provided or intended.

      9. Pursuant to their "Policy Statement or Cooperative Research and
Development Agreements and Intellectual Property Licensing," NIH and ADAMHA may
permit their investigators to enter into CRADAs (and thereby promise an option
to acquire intellectual property rights) in exchange for the contribution of
"essential research materials ... not otherwise reasonably available." If the
Research Material transferred by this MTA is so certified below, Provider and
the NIH/ADAMHA (when Recipient) investigator should submit a formal CRADA for
NIH/ADAMHA approval. For nongovernmental entities that regularly provide
research materials to NIH or ADAMHA, it is suggested that a master CRADA be
negotiated under which a certification below will suffice to invoke the
provisions of the CRADA. If Provider and Recipient otherwise decide to engage in
a cooperative research or development project using the Research Material, a
formal CRADA must also be negotiated. For general inquiries regarding CRADAs or
NIH/ADAMHA technology transfer policies, contact the Office of Invention
Development at (301) 496-0750.

             For receipt of Research Material under this Paragraph, when a
master CRADA governing material transfers is in effect between NIH or ADAMHA and
Provider, the NIH/ADAMHA investigator must identify the CRADA by NIH/ADAMHA
reference number:                      , and provide a more detailed description
than in Paragraph 2., above, of the specific extent of activities within the
overall Research Project to which the provisions of the CRADA will pertain (use
an attachment page if necessary). Signature by the investigator and authorized
official below constitutes certification that the Research Material transferred
by this MTA is essential and not otherwise reasonably available for the
following activities:
________________________________________________________________________________
________________________________________________________________________________
________________________________________________________________________________

      10. This MTA shall be construed in accordance with Federal law as applied
by the Federal courts in the District of Columbia.
