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 and the nine month period
are not necessarily indicative of results for the year.

Inventories
- -----------

Inventories are stated at the lower of cost or market using the average cost
method.

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS

Summary Analysis
- ----------------

In this third quarter of fiscal year 2000, BIOQUAL (hereinafter, "the Company"
or "BIOQUAL") realized net income of $10,153.  Net income for the first nine
months of fiscal year 2000 totaled $45,455.

On December 31, 1999, Diagnon Corporation ("Diagnon") changed its name to
BIOQUAL, Inc.  The name change was effected as a result of the merger of Diagnon
and its wholly owned subsidiary, BIOQUAL, Inc., with Diagnon being the surviving
corporation.  In the merger Diagnon adopted the name BIOQUAL, Inc. as the name
of the surviving entity.  The business and operations of BIOQUAL, Inc. will be
the same as the consolidated business and operations of Diagnon together with
its wholly owned subsidiaries prior to the merger.

During the third quarter the following developments occurred:

  .   On December 28, 1999, BIOQUAL renewed its contract to support hepatitis
      researchers at the National Institute of Allergy and Infectious Diseases
      (NIAID). The contract entitled "Care and Housing of Hepatitis Research
      Animals" totals $13,634,742 and extends for seven years to December 2006.

  .   On January 28, 2000, BIOQUAL renewed its contract to support AIDS
      researchers at the NIAID. The contract entitled "Care and Housing of AIDS
      Research Animals" totals $10,798,411 and extends for seven years to
      January 2007.

  .   On February 29, 2000, the Company renewed its contract to support
      infectious disease researchers at the NIAID. The contract entitled
      "Facility for Animals Used in Infectious Disease Research" totals
      $6,298,647 and extends for seven years to February 2007.

Subsequent to the end of the quarter the following developments occurred:

  .   On March 2, 2000, the Company was awarded a $99,153 Phase I grant from the
      National Institutes of Health as part of its Small Business Innovation
      Research (SBIR) program. The six month grant

                                       6
<PAGE>

      is to identify and characterize DNA sequence variation in chimpanzees at
      four genes that contain mutations implicated in the pathogenesis of
      Alzheimer's Disease.

  .   The NIAID contract, "MAO/Evaluation of AIDS Vaccines in Non-Human
      Primates" expired on March 31, 2000. This contract accounts for
      approximately 1% of the Company's projected revenues for fiscal year 2000.
      The expiration of this contract will have minimal effect on the Company's
      revenues and operating capital.

Year 2000
- ---------

The Company performed an internal assessment of the scope of the Year 2000
computer systems and software problems and its potential effect on the operation
of the Company.  The Company continues to monitor its information and non-
information systems for signs of malfunction due to the Year 2000 computer
problem.  The Company has not encountered any delays of service or non-service
from its major suppliers of products and services, however there can be no
assurance that the Company will not be affected by another company's Year 2000
non-compliance. The Company spent approximately $20,000 in fiscal year 1999 and
approximately $23,000 to date in fiscal year 2000 to replace non-compliant
computers and software.  Any costs incurred in connection with Year 2000
compliance were expensed as incurred.  It is the opinion of management that the
Year 2000 computer problem will not have a material effect on the Company's
operation.  However, the Company continues to monitor the status of its largest
customer, the National Institutes of Health (NIH), regarding Year 2000
compliance.  The NIH states that all of its mission critical systems and 98% of
its non-mission critical systems are currently compliant.  However, if the NIH
does experience Year 2000 related problems, the Company's financial condition
may be adversely affected until such time that the NIH's non-compliant
contingency plan is initiated.

Not all instances of date failure can be anticipated or controlled.  In planning
for the most reasonably likely worst-case scenario, (e.g. NIH systems being non-
compliant after January 1, 2000), or in cases which, despite our efforts,
failures occur, we have developed a contingency plan.  The contingency plan
includes the stockpiling of critical materials necessary to maintain operations.

Results of Operations
- ---------------------

Three Months Comparison
- -----------------------

For the three months of operations ended February 29, 2000 (the Company's third
quarter in fiscal year 2000), contract revenues increased by 8.2% or $217,731 to
$2,867,429 compared to $2,649,698 in the third quarter of fiscal year 1999.
This increase was due to increased government contract activity including
approximately $69,000 in costs incurred related to a toxicity study which began
this quarter.  However, the increase is not as large as anticipated due to a
decrease in the number of commercial contracts compared to the third quarter of
fiscal year 1999 and the expiration of a major contract on November 8, 1998.
Product sales increased to $55,299 for the quarter ended February 29, 2000
compared to $35,897 for the same quarter in fiscal year 1999.

                                       7
<PAGE>

Contract operating expenses increased 8.1% or $170,268 compared to the third
quarter of fiscal year 1999 primarily due to increased government contract
activity (including the $69,000 in costs incurred related to a toxicity study as
mentioned above), an increase in overhead expenses supporting the equine
production facility of approximately $35,000 compared to the third quarter in
fiscal year 1999, offset by the decrease in commercial contracts. Cost of goods
sold increased to $40,892 from $27,253 in the third quarter of fiscal year 1999.
This increase was primarily due to the increase in units sold during this fiscal
year. Research and development (R&D) expenses decreased to $33,947 compared to
$54,749 in the third quarter of fiscal year 1999. This decrease is primarily due
to the temporary reassignment of R&D staff to prepare Small Business Innovative
Research (SBIR) grant proposals to possibly provide additional funding for the
research associated with the high throughput assay system currently being
developed by the Company's Department of Discovery Research. General and
administrative expenses increased 17.7% compared to the third quarter of fiscal
year 1999 primarily due to inflationary increases in several items of expense
plus the increased costs associated with the preparation of the SBIR grant
proposals this quarter compared to fiscal year 1999. Total operating expenses
increased 9.3% due to the above.

Operating income decreased to $30,389 for the third quarter of fiscal year 2000
compared to $38,341 in the same quarter in the prior year.  The decrease is
primarily due to the following factors: 1) the increase in contract expenses
without a comparative increase in related contract revenues resulting in a
decrease in the gross margin percentage on contracts this fiscal year, 2) the
increase in overhead expenses supporting the equine production facility of
approximately $35,000, offset by 3) the increase in government contract
activity.

For this quarter, the Company had interest expense of $14,387 compared to
interest expense of $16,067 in the prior year.

In accordance with SFAS No. 109, "Accounting for Income Taxes", the Company
reported a deferred federal income tax expense of $4,000 for the three months
ended February 29, 2000.  The Company made a provision for state income tax
which is estimated at $3,000.  State income tax expense is reimbursable under
government contracting regulations.

Earnings Per Share (EPS) - For the three month comparison, options to purchase
29,502 shares of common stock at prices ranging from $2.8875 per share to $3.375
per share were outstanding on February 29, 2000 but were not included in the
computation of diluted EPS because the option exercise prices were greater than
the market price of the common shares. Options to purchase 59,345 shares of
common stock at prices ranging from $1.80 per share to $3.375 per share were
outstanding on February 28, 1999 but were not included in the computation of
diluted EPS because the option exercise prices were greater than the market
price of the common shares.

Nine Month Comparison
- ---------------------

For the nine months of operations ended February 29, 2000, contract revenues
increased by 6.7% or $536,540 to $8,564,407 compared to $8,027,867 for the first
nine months of fiscal year 1999.  This increase was due to increased government
contract activity including two one-time

                                       8
<PAGE>

purchases totaling approximately $210,000 during the second quarter of this
fiscal year and $69,000 in costs incurred related to a toxicity study which
began during the third quarter of this fiscal year. However, the increase is not
as large as anticipated due to a decrease in the number of commercial contracts
compared to the first nine months of fiscal year 1999, the end of a major
contract on November 8, 1998, the fiscal year 1999 funding of a $34,976 indirect
rate variance cost overrun of a contract that expired in fiscal year 1995 (the
contract was administratively closed out on September 30, 1998), and a fiscal
year 2000 reserve for a $50,000 cost overrun, due to indirect cost variances, on
a contract that expired on December 27, 1999. Product sales increased to $94,809
for the nine month period ending February 29, 2000 compared to $42,975 for the
same period in fiscal year 1999. Contract operating expenses increased 10.5% or
$647,166 compared to the first nine months of fiscal year 1999 primarily due to
increased government contract activity (including the two one-time purchases
totaling approximately $210,000 and the $69,000 toxicity study mentioned above),
an increase in overhead expenses supporting the equine production facility of
approximately $95,000 compared to the first nine months in fiscal year 1999,
offset by the decrease in commercial contracts. Cost of goods sold increased to
$76,932 from $36,643 in the first nine months of fiscal year 1999. This increase
was primarily due to the increase in units sold during this fiscal year and the
expensing of 22 free doses of Eqstend. Research and development (R&D) expenses
decreased to $134,818 compared to $140,956 in the first nine months of fiscal
year 1999. This decrease is primarily due to the temporary reassignment of R&D
staff (during the third quarter of fiscal year 2000) to prepare Small Business
Innovative Research (SBIR) grant proposals to possibly provide additional
funding for the research associated with the high throughput assay system
currently being developed by the Company's Department of Discovery Research as
previously mentioned. General and administrative expenses increased 8.6%
compared to the first nine months of fiscal year 1999 primarily due to
inflationary increases in several items of expense plus the increased costs
associated with the preparation of the SBIR grant proposals during the third
quarter of fiscal year 2000 compared to fiscal year 1999, offset by a decrease
in legal expenses during this year compared to fiscal year 1999. Total operating
expenses increased 10.4% due to the above.

Operating income decreased to $115,678 for the nine month period ending February
29, 2000 compared to $328,648 for the same period in the prior year.  The
decrease is primarily due to several factors: 1) the increase in contract
expenses without a comparative increase in related contract revenues resulting
in a decrease in the gross margin percentage on contracts this fiscal year, 2)
the increase in overhead expenses supporting the equine production facility of
approximately $95,000, 3) the reserve for a $50,000 cost overrun, due to
indirect cost variances, on a contract that ended on December 27, 1999 and 4)
$34,976 increased funding to cover an indirect cost overrun for an expired
contract during the previous fiscal year as mentioned above.

For the nine months of this fiscal year, the Company had interest expense of
$41,994 compared to interest expense of $41,471 in the prior year.

In accordance with SFAS No. 109, "Accounting for Income Taxes", the Company
reported a deferred federal income tax expense of $9,000 for the nine months
ended February 29, 2000.  The Company made a provision for state income tax
which is estimated at $22,000.  State income tax expense is reimbursable under
government contracting regulations.

Earnings Per Share (EPS) - For the nine month comparison, options to purchase
29,502 shares of common stock at prices ranging from $2.8875 per share to $3.375
per share were outstanding on February 29, 2000 but were not included in the
computation of diluted EPS because the option exercise prices were greater than
the market price of the common shares. Options to purchase 59,345 shares of
common stock at prices ranging from $1.80 per share to $3.375 per share were
outstanding on February 28, 1999 but were not included in the computation of
diluted EPS because the option exercise prices were greater than the market
price of the common shares.

Liquidity and Capital Resources
- -------------------------------

Assets

The changes in cash and cash equivalents are detailed in the Statements of
Consolidated Cash Flows on page 5.  Total assets increased $269,953 from
$4,623,734 at May 31, 1999 to $4,893,687 at February 29, 2000.  This amount was
primarily attributable to an increase in accounts receivable of $188,636
consisting mainly of 1) an increase of $318,176 in trade accounts receivable
reflecting a slower collection rate compared to the previous fiscal year end, 2)
a $121,782 net decrease in unbilled accounts receivable (current plus
noncurrent) primarily resulting from a $1,427 increase in reimbursable indirect
rate variances for the current fiscal year, a net $92,976 decrease in month end
accrued sales on accrued direct labor comparing the current period and the
accrual at the end of fiscal year 1999, the recording of $19,767 unbilled
contract fee retention to be billed at the completion of the respective
contracts, and a $50,000 reserve for a cost overrun, due to indirect rate
variances from prior years, on a contract that expired on December 27, 1999, and
3) a $7,758 decrease in other accounts receivable.  Prepaid expenses increased
$7,535 primarily due to the prepayment of life insurance premiums.  Fixed
assets, net of accumulated depreciation and amortization increased $144,077
reflecting fixed asset purchases of $367,234 (mainly nonhuman primate
enclosures, lab equipment, and facility improvements) offset by depreciation and
amortization of $223,157.

The above increase is partially offset by 1) a decrease in loans to officers of
$32,906 due to payments made during the this fiscal year, 2) a deferred income
tax decrease of $9,000 primarily as a result of utilizing a portion of the
federal income tax loss carryforward, and 3) a $30,806 decrease to inventories.
The balance of the increase was due to other miscellaneous factors.

Liabilities

In the first nine months of operations, total liabilities increased $256,244
from $1,127,598 at May 31, 1999 to $1,383,842 at February 29, 2000.  This
increase is primarily attributable to an increase to borrowings under line-of-
credit of $549,847 reflecting the slow

                                       10
<PAGE>

collection of trade accounts receivable and the payment of accrued bonuses from
the previous fiscal year.

The above increase is partially offset by 1) a decrease in accrued compensation
and related costs of $187,975 reflecting the payment of accrued bonuses from
fiscal year 1999 during the first quarter of this fiscal year and a shorter
accrual period at the end of the quarter compared to the prior fiscal year end.
2) payments totaling $51,553 on capital leases reducing long-term debt, 3) a
decrease in accrued income taxes of $24,281, 4) a decrease in accounts payable
of $22,780, and 5) a decrease in other accrued liabilities of $7,014.  The
balance of the increase was due to other miscellaneous factors.

Stockholders' Equity

During the second quarter the company paid a cash dividend totaling $17,363 to
shareholders of record as of September 7, 1999.

Capital Resources

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.

     of fixed fee shall not be made in less than monthly increments.

c.   The Government's obligation, represented by the sum of the estimated cost
     plus the fixed fee for this contract is $13,634,742.

d.   Total funds currently available for payment and allotted to this contract

e.   It is estimated that the amount currently allotted will cover performance
     of the contract through December 27, 2000.

     the concurrence of the Contractor.

ARTICLE B.3. PROVISIONS APPLICABLE TO DIRECT COSTS

     Project Manager.  No Contractor employee will be directly supervised by the
     Government.  All individual employee assignments, and daily work direction,
     shall be given by the applicable employee supervisor.  If the Contractor

     Officer of this communication or action.

(2)  The contractor agrees to immediately notify the contracting officer in
     writing if there is an anticipated overrun (any amount) or unexpended
     balance (greater than 10 percent) of the amount allotted to the contract,
     and the reasons for the variance.  Also refer to the requirements of the
     Limitation of Funds and Limitation of Costs Clauses in the contract.

(3)  Overtime (premium) pay costs shall not exceed a total of $76,180 unless
     prior approval is granted by the Contracting Officer via a Contract
     modification.

(4)  The contractor may charge directly to this contract an equal monthly amount
     for the depreciation of each Animal Enclosure (cage) use for this project,
     not to exceed a ten (10) year recovery period from the date the enclosure
     was first placed in service.  The contractor shall add Enclosure
     refurbishing costs to its overhead pool.

(5)  Fringe Benefits, Overhead and G&A rates, as proposed in Bioqual,
     Incorporated Final Revised Offer, dated December 13, 1999, are accepted for

SECTION H - SPECIAL CONTRACT REQUIREMENTS

ARTICLE H.l. REIMBURSEMENT OF COSTS FOR INDEPENDENT RESEARCH AND DEVELOPMENT
PROJECTS (Commercials Only)

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.


                                       9
<PAGE>

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. NEEDLE EXCHANGE

a. Pursuant to Public Law(s) cited in paragraph b., below, contract funds shall
   not be used to carry out any program of distributing sterile needles or
   syringes for the hypodermic injection of any illegal drug.

b. Public Law 106-113 Section 505       Federal Fiscal Year 2000

ARTICLE H.3. 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 I-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.4. PRESS RELEASES

a. Pursuant to Public Law(s) sited in paragraph b., below, the contractor shall
   clearly state, when issuing statements, press releases, requests for
   proposals, bid solicitations and other documents describing projects or
   programs funded in whole or in part with Federal money: (1) the percentage of
   the total costs of the program or project which will be financed with Federal
   money; (2) the dollar amount of Federal funds for the project or program; and
   (3) the percentage and dollar amount of the total costs of the project or
   program that will be financed by nongovernmental sources.

b. P.L. 106-113 Section 507             Federal Fiscal Year 1999

                               STATEMENT OF WORK

Independently and not as an agent of the Government, the Contractor shall be
required to furnish all the necessary services, qualified personnel, material,
equipment, and facilities, not otherwise provided by the Government as needed to
perform the work set forth below.

A. Specifically, the Contractor shall:

   1. Provide continued housing, feed and care for an estimated 110 non-human
   primates, consisting of approximately 25 infant and juvenile chimpanzees, 80
   Old World and New World non-human primates and a small amount of species
   other than non-human primates (consisting primarily of woodchucks, but on
   occasion rats, mice, rabbits or Guinea pigs). The use of species other than
   non-human primates will represent a small part (less than 1%) of the level of
   effort for the Statement of Work. The Contractor must only state their
   capability and willingness to accommodate species other than non-human
   primates. No cost information for species other than non-human primates is
   required. However, if the costs associated with work using species other than
   non-human primates appear that they will exceed 1%, fiscal accounting will be
   required.

   2. Perform routine procedures on these animals which shall include, but not
   be limited to: inoculation of the animals with various hepatitis agents,
   monitoring animals for signs of disease, treatment with therapeutic regimens,
   and collection of specimens as descried by protocols furnished by the Project
   Officer. The performance of specialized tests on specimens collected by the
   Contractor shall be the responsibility of Government scientists. However the
   costs associated with collection of specimens such as blood, samples for
   virus isolation, and specimens for pathologic observations shall be the
   responsibility of the Contractor. It is estimated that the following shall be
   required:

   a. Procedures:  (1) Inoculations: Intravenous, intraperitoneal, subcutaneous,
   and intra muscular (2) Ultrasound-guided transfection of the liver and liver
   biopsy and bile aspiration (3) Plasmapheresis (4) Leukopheresis (5) Lavages
   (6) Gavages (7) Biopsies: Liver, lymph node, intestine, bone marrow, CSF,
   skin, bile. (8) Dynamic color flow abdominal imaging and echocardiography.

   b. Specimens:  Liver, CSF, sera, plasma, PBMC, lymph node, intestine, bone
   marrow, lavage/gavage samples, bile, feces, skin.

   c. Survival Surgery: Laparotomy to collect up to 10% of the liver by open
   biopsy; laparotomy-guided transfection of the liver or liver biopsy.

   d. Necropsy:  Comprehensive necropsy at completion of terminal studies.

   Deliver upon request, clinical specimens, drawn freshly from the animal, to
   NIAID within 2 hours after being drawn; preferably by 11:00 A.M. on the day
   obtained in order to achieve optimal virus viability.

   The Contractor's professional and technical personnel assigned to the
   contract shall meet with scientists in the Hepatitis Viruses Section and
   Molecular Hepatitis Section, Laboratory of Infectious Diseases, NIAID,
   Building 7, Room 202, Bethesda, Maryland biweekly to monthly as needed for 2
   hours, commencing at 1400-1500 hours.

   The Contractor shall function as a central receiving and shipping point and
   repository for samples exchanged between USA and international collaborators
   with NIAID scientists.

   Conduct some protocols in accordance with 21 CFR, Chapter 1, Food and Drug
   Administration, Part 58-Good Laboratory Practices For Nonclinical Laboratyory
   Studies.

   3. Physical Plant:

   a. Biosafety Level:  ABSL-2 practices, containment equipment, and facilities
   are required for activities using non-human primates and small animals
   experimentally infected with viruses in this 1. above and other latent or
   intercurrent infections associated with these species.

   b. Animal rooms: Provide the Project Officer separate rooms dedicated to this
   contract (no commingling of animals from other projects) which are
   environmentally controlled with non-recirculating air which is exchanged 10-
   15 times per hour. Negative air

                                      18
<PAGE>

pressure relative to non-containment areas shall be accomplished by an
independent exhaust fan system.

   c. Exhaust Air: Pass exhaust air through absolute HEPA filters.  All
   biocontainment modules will be attached directly to the building exhaust
   system by flexible tubing. Al of the air exhausted from a room will be drawn
   through cages when the room is fully fitted with the biocontainment units.
   Air entering biocontainment units will pass through a medium efficiency
   filter while the air leaving a unit will move through the exhaust system and
   be HEPA filtered before exiting the building. Back-up exhaust fans shall be
   used to insure operational integrity of this system at all times.

   d. Special Procedures Rooms: Provide suitable and separate rooms and
   equipment consistent with the Guide for animal examination, necropsy,
   surgery, surgical preparation, and radiography. The necropsy room will
   contain workstations and a downdraft ventilation necropsy table which meets
   OSHA and ASHRAE standards for exposure limits to formalin.

   e. Storage Areas: Provide up to 500 square feet of secure floor and shelf
   space for the storage of all equipment, supplies, and pharmaceutical
   products. All pharmaceutical products (i.e., for treatment of intercurrent
   infections, all tranquilizers, all analgesics), supplies and equipment (i.e.,
   for specimen collection, inoculation, biopsy, surgery, necropsy, etc.), shall
   be specified by the Project Officer, and supplied by the Contractor.

   f. Alternative Power Supply: An emergency electric generator shall be
   available to this project and available for immediate use in the event of a
   loss of electric power.

   g. Security: Provide a 24-hour security system and 24 hour security personnel
   to prevent unauthorized entry. Restrict entrances into the animal areas by
   locks and animal rooms shall display signs marked boldly with the designation
   "Biohazard Area" on animal room doors. Signs shall list the precautions
   necessary when entering the area(s) and entry shall be limited to authorized
   personnel only.

      passage between adjacent cages thus enhancing safety, security,
      efficiency, operational flexibility, and attention to psychological well-
      being. This system permits and fosters social housing of primates in
      accordance with the USDA/APHIS regulations under the Animal Welfare Act
      and USPHS policy. The caging shall promote the psychological well being of
      the animals while minimizing exposure to infectious agents. The 6.0 Mobile
      Home Over/Under Biocontainment Modules are essential for hepatitis virus

      as well as an enriched environment including an adjacent exercise area.
      Specifically, the air handling shall prevent the acquisition of viruses,
      especially respiratory viruses, by the chimpanzees from their animal
      handlers and vice versa. The primary enclosure shall be at least 25 sq.
      ft. of floor space with an internal height of 84 inches. An adjacent
      exercise area shall be at least 35 sq. ft. of floor space with an interior
      height of 84 inches. The primary enclosure shall be equipped with a
      squeeze mechanism to gain control of the chimpanzee for injections or to
      persuade the chimpanzee to enter a transfer cage. The primary enclosure
      shall have an adjacent service area door that can be closed when the
      chimpanzee is being manipulated. When required, chimpanzees shall be
      individually housed with exclusive access to both a primary enclosure area
      and an exercise area. Individually housed chimpanzees shall have visual
      contact with conspecifics. These enclosures shall be designed to be washed

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.

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.

   Independently and not as an agent of the Government, the Contractor shall be
   required to furnish all the necessary services, qualified personnel,
   material, equipment, and facilities, not otherwise provided by the Government
   as needed to perform the work set forth below.

   The Contractor shall adhere to the following:

   1  The institution must have the following credentials: a. AAALAC
      International file number b. OPRR Animal Welfare Assurance number c. USDA
      R Registration (Class "R" Research).

   2  The facility in which the animals are housed shall be operated in
      compliance with: a. The Animal Welfare Act (P.L. 89-544, as amended) Rules
      and Regulations published in the Code of Federal Regulations (CFR), Title
      9 (Animals and Animal Products), Chapter 1, Subchapter A (Animal Welfare),
      Parts 1,2, and 3.b. Public Health Service (PHS) Policy on Humane Care and
      Use of Laboratory Animals, updated 1996. c. The Guide for the Care and Use
      of Laboratory Animals, revised 1996. d. NIH Manual 3040-3 Intramural
      Contracts Involving Animals. e. Biosafety in Microbiological and

      Prevention and Treatment of B-Virus Infections in Exposed Persons
      (Clinical Infectious Diseases, 1995; 20: 421-439). h. New Ceropithecine
      herpesvirus 1 (CHV-1) guidelines (to be established).

   3  All nonhuman primates housed under this contract will be provided by the
      Government.

   4  All Animal Study Proposals for procedures that are to be performed on
      NIAID owned animals will be prepared by the NIH, NIAID scientists and
      submitted to the Contractor through the Project Officer or his/her
      designee.

   5  At the conclusion, the disposition of the animals shall be the
      responsibility of the NIH, NIAID.

   Specifically, the Contractor shall:

   1  House, feed and care for an estimated 200 nonhuman primates including but
      not limited to the following species: Macaca mulatta, Macaca nemestrina,
      Cercopithecus, and any other combination of Old World and New World
      species. Conduct up to 10 procedures per year with each experimental group
      consisting of 4 to 12 nonhuman primates using one or more viruses. The
      nature of investigations being conducted by the NIAID scientists using
      simian immunodeficiency viruses require long-term, overlapping, labor
      intensive studies which will necessitate that animals be maintained for

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.

Notwithstanding any other clause in this contract, the Contractor will not be

prior written approval of the Contracting Officer.

   67 -  Photographic Equipment

   74 -  Office Machines and Visible Record Equipment

property sources, provided the request is made under a cost-reimbursement
contract.  Extensions or renewals of approved existing leases or rentals for
equipment in these Federal Supply Groups are excluded from the provisions of
this article.

SECTION H - SPECIAL CONTRACT REQUIREMENTS

ARTICLE H.l. REIMBURSEMENT OF COSTS FOR INDEPENDENT RESEARCH AND DEVELOPMENT
PROJECTS (Commercials Only)

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. NEEDLE EXCHANGE

a. Pursuant to Public Law(s) cited in paragraph b., below, contract funds shall
   not be used to carry out any program of distributing sterile needles or
   syringes for the hypodermic injection of any illegal drug.

b. Public Law 106-113 Section 505; Federal Fiscal Year 2000

ARTICLE H.3.  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 I-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. PRESS RELEASES

a. Pursuant to Public Law(s) sited in paragraph b., below, the contractor shall
   clearly state, when issuing statements, press releases, requests for
   proposals, bid solicitations and other documents describing projects or
   programs funded in whole or in part with Federal money: (1) the percentage of
   the total costs of the program or project which will be financed with Federal
   money; (2) the dollar amount of Federal funds for the project or program; and
   (3) the percentage and dollar amount of the total costs of the project or
   program that will be financed by nongovernmental sources.

b. P.L. 106-113 Section 507; Federal Fiscal Year 2000

ARTICLE H.5. REPORTING MATTERS INVOLVING FRAUD, WASTE AND ABUSE

Anyone who becomes aware of the existence or apparent existence of fraud, waste
and abuse in NIH funded programs is encouraged to report such matters to the
DHHS Inspector General's Office in writing or on the Inspector General's
Hotline.  The toll free number is 1-800-DHHS-TIPS (1-800-447-8477).  All
telephone calls will be handled confidentially.  The e-mail address is

                               STATEMENT OF WORK

Independently and not as an agent of the Government, the Contractor shall be
required to furnish all the necessary services, qualified personnel, material,
equipment, and facilities, not otherwise provided by the Government as needed to
perform the work set forth below.

A. Specifically, the Contractor shall:

   1. House, feed and care for an estimated 68 Old World and/or New World non-
      human primates, in addition to an estimated 6 chimpanzees and 12 small
      animals (e.g. rabbits) at all times. (Note to Offeror: The use of species
      other than non-human primates will represent a small part (less than 2%)
      of the level of effort for the Statement of Work. The Contractor must only
      state their capability and willingness to accommodate species other than
      non-human primates. No cost information for species other than non-human
      primates is required. However, if the costs associated with work using
      species other than non-human primates appear that they will exceed 2%,
      fiscal accounting will be required.)

   2. Conduct an estimate of 12 procedures per year designed by the Project
      Officer, each utilizing approximately 24 monkeys and one or more viruses,
      that last generally one month in duration (occasionally two months).
      Conduct an estimate of four procedures per year also designed by the
      Project Officer with six chimpanzees that last form one to three months.
      Alternatively, a small number (approximately 4 or less) of procedures
      shall be conducted on small animals (e.g. rabbits, ferrets) when specified
      by the Project Officer. Procedures will be conducted according to
      individual working protocols issued under NIAID ACUC approved Animal Study
      Proposals. Viruses to be tested include, but are not limited to, the
      following:

           a. Wild type and attenuated parainfluenza, respiratory syncytial,
              influenza A and B viruses, and measles virus.
           b. Vaccinia wild type and recombinant viruses.
           c. Attenuated and wild type adenoviruses, including recombinant
              adenovirus.
           d. Rotaviruses.
           e. Norwalk-like viruses.
           f. Flaviviruses.

   3. Administer new therapies such as antiviral agents and immunotherapies and
      record their effectiveness against viral infection and collect specimens
      as described in protocols furnished by the Project Officer.

      Produce polyclonal antibodies in SPF rabbits under conditions of isolation
      to prevent the acquisition of adventitious pathogens by the rabbit. The
      method for production of the polyclonal antibodies will be the creation of
      whiffle-ball chambers by surgical implantation, two per rabbit (Clemons,
      et al. Evaluation of a subcutaneously implanted chamber for antibody
      production in rabbits. Laboratory Animal Science 42: 307-311)

      Monkeys will be pre-conditioned for use on experimental protocols
      following arrival and during quarantine. Post-study animals will be held
      (generally 1-4 weeks) until disposition and transportation are arranged by
      the Government.

      The performance of specialized tests on specimens collected by the
      Contractor shall be the responsibility of Government scientists. However
      the costs associated with collection of specimens such as blood, samples
      for virus isolation, and specimens for pathologic observations shall be
      the responsibility of the Contractor. It is estimated that the following
      shall be required:

               a. Five (5) blood specimens per animal.
               b. Ten (10) nasopharyngeal swabs per animal.
               c. Four (4) tracheal lavages per animal.
               d. Up to 1,000 pathologic specimens (total).

      In some instances, clinical specimens, drawn fresh daily from the animal,
      shall be delivered intact, on wet ice, to NIH, Building 7, Respiratory
      Viruses Section, within 2 to 4 hours after having been drawn, by 1:00 P.M.
      on the day obtained in order to achieve optimal and maximum virus
      isolation and recovery rates. In most procedures, specimens shall be
      frozen at -70C until delivery on dry ice.

<PAGE>

     and small animals experimentally infected with viruses in this 1. above and
     other latent or intercurrent infections associated with these species.

  b. Animal rooms: Provide the Project Officer separate rooms dedicated to this
     contract (no commingling of animals from other projects) which are
     environmentally controlled with non-recirculating air which is exchanged
     10-15 times per hour. Negative air pressure relative to non-containment
     areas shall be accomplished by an independent exhaust fan system.

  c. Exhaust Air: Pass exhaust air through absolute HEPA filters. All
     biocontainment modules will be attached directly to the building exhaust
     system by flexible tubing. Al of the air exhausted from a room will be
     drawn through cages when the room is fully fitted with the biocontainment
     units. Air entering biocontainment units will pass through a medium
     efficiency filter while the air leaving a unit will move through the
     exhaust system and be HEPA filtered before exiting the building. Back-up
     exhaust fans shall be used to insure operational integrity of this system
     at all times.

  d. Special Procedures Rooms: Provide suitable and separate rooms and equipment
     consistent with the Guide for animal examination, necropsy, surgery,
     surgical preparation, and radiography. The necropsy room will contain
     workstations and a downdraft ventilation necropsy table which meets OSHA
     and ASHRAE standards for exposure limits to formalin.

  e. Storage Areas: Provide up to 500 square feet of secure floor and shelf
     space for the storage of all equipment, supplies, and pharmaceutical
     products. All pharmaceutical products (i.e., for treatment of intercurrent

     to prevent unauthorized entry. Restrict entrances into the animal areas by
     locks and animal rooms shall display signs marked boldly with the
     designation "Biohazard Area" on animal room doors. Signs shall list the
     precautions necessary when entering the area(s) and entry shall be limited
     to authorized personnel only.

  5. Animal Environment, Housing, and Management:

   a.  Caging Specifications:

       (1) The Contractor shall provide a combination of 6.0 Mobile Home
           Over/Under Modules and 6.0 Mobile Home Over/Under Biocontainment
           Modules. These mobile modular cages are designed to allow docking
           with adjacent cages and opening of transparent plexi-glass shuttle
           doors to allow animal passage between adjacent cages thus enhancing
           safety, security, efficiency, operational flexibility, and attention
           to psychological well-being. This system permits and fosters social
           housing of primates in accordance with the USDA/APHIS regulations
           under the Animal Welfare Act and USPHS policy. The caging shall
           promote the psychological well being of the animals while minimizing
           exposure to infectious agents. The 6.0 Mobile Home Over/Under
           Biocontainment Modules are essential for hepatitis virus research.

       (2) Chimpanzee housing shall be of a design that provides biocontainment
           as well as an enriched environment including an adjacent exercise
           area. Specifically, the air handling shall prevent the acquisition of
           viruses, especially respiratory viruses, by the chimpanzees from
           their animal handlers and vice versa. The primary enclosure shall be
           at least 25 sq. ft. of floor space with an internal height of 84
           inches. An adjacent exercise area shall be at least 35 sq. ft. of
           floor space with an interior height of 84 inches. The primary
           enclosure shall be equipped with a squeeze mechanism to gain control
           of the chimpanzee for injections or to persuade the chimpanzee to
           enter a transfer cage. The primary enclosure shall have an adjacent
           service area door that can be closed when the chimpanzee is being
           manipulated. When required, chimpanzees shall be individually housed
           with exclusive access to both a primary enclosure area and an
           exercise area. Individually housed chimpanzees shall have visual
           contact with conspecifics. These enclosures shall be designed to be
           washed and disinfected in place.

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.
