respectively).  Contract Operating Expenses decreased 7.6% primarily due to
decreased contract activity  offset by costs incurred associated with the
production of Equine IgG which the Company intends to market and sell during
the first half of the next calendar year.  General and Administrative Expenses
(G&A) decreased 14.5% compared to the prior year.  During the same quarter last
year, the Company wrote off approximately $104,000 related to the termination
of the agreements between Diagnon and The Johns Hopkins University (see
November 1994 10-QSB).  The decrease in G&A is the net result of the prior year
write off and an increase in current year expenses resulting from annual salary
increases and the addition of a full-time legal counsel.  Total Operating
Expenses decreased 9.1% primarily due to the expiration of the two contracts
mentioned above.

Operating Income decreased 49.8% compared to the prior year primarily due to
decreased contract activity and to the costs incurred associated with the
production of Equine IgG as stated above.

For this quarter, Diagnon had interest expense of $12,341 compared to interest
expense of $9,769 in the prior year.  The increase is primarily attributable to
capitalized leases at higher interest rates.

Six Months Comparison

For the six months of operations ended November 30, 1995, Contract Revenues
decreased by 10.3% compared to the prior year primarily due to decreased
contract activity.  Contract Operating Expenses decreased 10.1% primarily due
to decreased contract activity offset by costs incurred associated with the
production of Equine IgG which the Company intends to market and sell during
the first half of the next calendar year.  General and Administrative Expenses
decreased 5.8% primarily due to the net result of the $104,000 prior year
write-off and the salary increases and additional staff as discussed in the
Three Months Comparison.  Total Operating Expenses decreased 9.3%, due to the
above.

Operating Income decreased 38.8% compared to the prior year primarily due to
decreased contract activity and to the costs incurred associated with the
production of Equine IgG as stated above.

For the six months of this fiscal year, Diagnon had interest expense of $19,986
compared to interest expense of $14,082 in the prior year.  The increase is
primarily attributable to capitalized leases at higher interest rates.

Liquidity and Capital Resources

Assets

The changes in Cash and Cash Equivalents are detailed in the Statements of
Consolidated Cash Flows on page 5.  Accounts Receivable have increased by
$224,667 consisting of 1) an increase of $359,432 to Unbilled Accounts
Receivable representing increases in reimbursable indirect rate variances of
$280,630 and unbilled accrued direct costs of $78,802 billed in December 1995,
2) a $141,036 decrease to Trade Receivables reflecting decreased contract
activity and a slightly faster than normal collections rate when compared to
the prior fiscal year end and 3) a $6,271 increase to a receivable from
ZooQuest Technologies LTD.  Prepaid Expenses increased by


                                      -7-
<PAGE>   9
$62,080 primarily due to the prepayment of $6,600 in life insurance premiums,
$21,100 in business insurance premiums, and $29,000 in real estate and personal
property taxes.  An increase in Fixed Assets, net of Accumulated Depreciation
and Amortization of $143,578 reflects fixed asset purchases of $270,520 (mainly
nonhuman primate housing units and an autoclave) offset by depreciation and
amortization of $126,942 during this six month period.  Other Noncurrent Assets
increased by $17,097 as the net result of the completion of a nonhuman primate
housing unit order from the previous fiscal year ($52,553) and a $70,000
deposit on a new order of eleven units during this quarter.

Deferred Income Taxes decreased by $24,000 primarily as a result of utilizing a
portion of the federal income tax loss carryforward.

Liabilities

In the first six months of operations, Total Liabilities increased $248,319.
This increase is primarily attributable to 1) an increase to Borrowings Under
Line-of-Credit of $223,793 necessitated by the increases in Prepaid Expenses
and Unbilled Accounts Receivable and Fixed Asset purchases as stated above, 2)
an increase in Long-Term Debt of $78,045 related to capital leases of $128,252
for nonhuman primate enclosures at the Research Boulevard Facility offset by
$50,207 of payments on capital leases, and 3) an increase in Other Accrued
Liabilities of $8,675 reflecting the accrual of an equine serum purchase for
the production of the equine IgG product.

The above increase is partially offset by a decrease in Accounts Payable of
$64,473 due to decreased contract activity.

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.

          listed in the Contractor's Guide for Control of Government Property,
          1990, regardless of acquisition value).

b.   Travel Costs

     (1)  Domestic Travel

          (a)  Total expenditures for domestic travel (transportation, lodging,
               subsistence, and incidental expenses) incurred in direct 
               performance of this MAO shall not exceed $-0- without the prior

               B.3.a. above and which shall be specifically approved in writing
               by the Contracting Officer.)
 
          (b)  The cost of travel by privately-owned automobile shall be 
               reimbursed at the mileage rate prescribed by the MAO Holder's 
               established, generally applicable travel policy in lieu of 
               actual costs, provided, however, that such reimbursement shall 
               not exceed the otherwise allowable comparative cost of travel 
               by common carrier.

          (c)  Reasonable actual costs of lodging and subsistence, or per diem 
               in lieu of actual costs, shall be allowable to the extent that 
               such actual costs or per diem amounts do not exceed the amounts 
               or per diem rates prescribed by the MAO Holder's established, 
               generally applicable travel policy.

          (d)  Any revision to the MAO Holder's established, generally

          travel of Master Agreement Order personnel will benefit and
          contribute to accomplishing the specific Master Agreement Order
          project, or will otherwise justify the expenditure of NIH Master
          Agreement Order funds; (e) how such advantages justify the costs for
          travel and absence from the project





                                       4
<PAGE>   6
          of more than one person if such are suggested; and (f) what additional
          functions may be performed by the travelers to accomplish other 
          purposes of the specific Master Agreement Order and thus further 
          benefit the project.


ARTICLE B.4. ADVANCE UNDERSTANDINGS

Other provisions of this MAO notwithstanding, approval of the following items
within the limits set forth is hereby granted without further authorization
from the Contracting Officer.

a.   The estimated level of effort set forth below is for guidance to serve not
     as a measure of the MAO Holder's obligation but as a further description
     of the required tasks.  It will represent the basis of direct labor agreed
     to in the MAO negotiations for the period from September 30, 1995 through

b.   The MAO Holder agrees to abide by the terms of FAR 52.247-63, Preference
     for U.S.-Flag Air Carriers.  This provision states in part that, in
     performing work under this MAO, the MAO Holder shall utilize U.S. flag air
     carriers unless service by those carriers is not available.  If U.S. flag
     air carriers are not available the MAO Holder shall so certify in writing
     and include that certification/justification in the request for advance
     approval of foreign travel. (Cost/lower fares are not acceptable reasons
     for proposing to utilize foreign air carriers.)

c.   If the MAO contains any specific limitations/ceilings on particular costs,
     these shall always prevail until modified in the MAO.

d.   The MAO Holder agrees that samples/products received from/through the
     Government for utilization under this MAO shall be used only for purposes
     required by this MAO.

e.   Publication of Manuscripts or Abstracts

     Because there is a likelihood that the MAO Holder will be evaluating
     proprietary compounds provided to the Government by a third party, it is
     essential to include provisions that will protect the rights of the third
     party suppliers as follows:

          The MAO Holder agrees that manuscripts/abstracts based on
          data/information generated under this MAO will not be submitted for
          publication until written Project Officer clearance has been
          received.  MAO support shall be acknowledged in all such
          publications. (Refer to Attachment 1, Work Statement, Item Number
          11.C.) A "publication" is defined as an issue of printed material
          offered for distribution or any communication or oral presentation of
          information.

          The Project Officer will review all manuscripts/documents in a period
          of time not to exceed 30 calendar days from receipt, and will either
          grant clearance for publication/disclosure, recommend changes or, as
          applicable, refer the document to the Supplier of the compound for
          their review.

          NIAID will use its best efforts to assist and expedite the review
          process by the Supplier wherever possible.

     FEDERAL ACQUISITION REGULATION (48 CFR CHAPTER 1) CLAUSE: 52.251-01,
          GOVERNMENT SUPPLY SOURCES


SECTION H - SPECIAL CONTRACT REQUIREMENTS

ARTICLE H.1. 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 totalling 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, will 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. ANIMAL WELFARE ASSURANCE

The Contractor shall perform all animal-related work under this contract in
accordance with Animal Assurance #A-3086-01.  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. SALARY RATE LIMITATION LEGISLATION PROVISIONS

a.   Pursuant to Public Law(s) cited in paragraph b., below, no NIH Fiscal Year
     funds may be used to pay the direct salary of an individual through this
     contract at a rate in excess of applicable amount shown for the fiscal
     year covered.  Direct salary is exclusive of overhead, fringe benefits and
     general and administrative expenses.  The per year salary rate limit also
     applies to individuals proposed under subcontracts.  If this is a
     multi-year contract, it may be subject to unilateral modifications by the
     Government if an individual's salary rate exceeds any salary rate ceiling
     established in future DHHS appropriation acts.

ARTICLE I.4. ADDITIONAL FAR CONTRACT CLAUSES INCLUDED IN FULL TEXT

a.   FAR Clause 52.202-1 DEFINITIONS (OCTOBER 1995)

     "....

     (b)  COMMERCIAL COMPONENT means any component that is a commercial item.

     (c)  COMMERCIAL ITEM means-

          (1)  Any item, other than real property, that is of a type customarily
               used for nongovernmental purposes and that-

               (i)  Has been sold, leased, or licensed to the general public; or

               (ii) Has been offered for sale, lease, or license to the general
                    public;

          (2)  Any item that evolved from an item described in paragraph (c)(1) 
               of this clause through advances in technology or performance and 
               that is not yet available in the commercial marketplace, but 
               will be available in the commercial marketplace in time to 
               satisfy the delivery requirements under a Government 
               solicitation;
 
          (3)  Any item that would satisfy a criterion expressed in paragraphs
               (c)(1) or (c)(2) of this clause, but for-

               (i)  Modifications of a type customarily available in the 
                    commercial marketplace; or

               (ii) Minor modifications of a type not customarily available in 
                    the commercial marketplace made to meet Federal Government
                    requirements.  "Minor" modifications means modifications 
                    that do not significantly alter the nongovernmental 
                    function or essential physical characteristics of an item 
                    or component, or change the purpose of a process.  Factors 
                    to be considered in determining whether a modification is 
                    minor include the value and size of the modification and 
                    the comparative value and size of the final product.  
                    Dollar values and percentages may be used as guideposts, 
                    but are not conclusive evidence that a modification is 
                    minor;

          (4)  Any combination of items meeting the requirements of paragraphs
               (c)(1), (2), (3), or (5) of this clause that are of a type
               customarily combined and sold in combination to the general 
               public;
 
          (5)  Installation services, maintenance services, repair services,
               training services, and other services if such services are 
               procured for support of an item referred to in paragraphs (c)(1),
               (2), (3), or (4) of this clause, and if the source of such 
               services-

               (i)  Offers such services to the general public and the Federal
                    Government contemporaneously and under similar terms and
                    conditions; and

               (ii) Offers to use the same work force for providing the Federal
                    Government with such services as the source uses for 
                    providing such services to the general public;

          (6)  Services of a type offered and sold competitively in substantial
               quantities in the commercial marketplace based on established 
               catalog or market prices for specific tasks performed under 
               standard commercial terms and conditions.  This does not include
               services that are sold based on hourly rates without an 
               established catalog or market price for a specific service 
               performed;

          (7)  Any item, combination of items, or service referred to in
               subparagraphs (c)(1) through (c)(6), notwithstanding the fact 
               that the item, combination of items, or service is transferred 
               between or among separate divisions, subsidiaries, or 
               affiliates of a Contractor; or

          (8)  A nondevelopmental item, if the procuring agency determines the
               item was developed exclusively at private expense and sold in
               substantial quantities, on a competitive basis, to multiple
               State and local Governments.

     (d)  COMPONENT means any item supplied to the Federal Government as part
          of an end item or of another component.

     (e)  NONDEVELOPMENTAL ITEM means-

          (1)  Any previously developed item of supply used exclusively for
               governmental [*48251] purposes by a Federal agency, a State or
               local government, or a foreign government with which the United
               States has a mutual defense cooperation agreement;

          (2)  Any item described in paragraph (e)(1) of this definition that
               requires only minor modification or modifications of a type
               customarily available in the commercial marketplace in order to
               meet the requirements of the procuring department or agency; or

          (3)  Any item of supply being produced that does not meet the
               requirements of paragraph (e)(1) or (e)(2) solely because the
               item is not yet in use...."

               *Subsections 27(a), (b), and (d) are effective on December 1,
               1990.  Subsection (f) is effective on June 1, 1991.

               THIS CERTIFICATION CONCERNS A MATTER WITHIN THE JURISDICTION OF
               AN AGENCY OF THE UNITED STATES AND THE MAKING OF A FALSE,
               FICTITIOUS, OR FRAUDULENT CERTIFICATION MAY RENDER THE MAKER

                             [End of certification]

     (d)  In making the certification in paragraph (2) of the certificate, the
          officer or employee of the competing Contractor responsible for the
          offer or bid, may rely upon a one-time certification from each
          individual required to submit a certification to the competing
          Contractor, supplemented by periodic training.  These certifications
          shall be obtained at the earliest possible date after an individual
          required to certify begins employment or association with the
          Contractor.  If a contractor decides to rely on a certification
          executed prior to the suspension of section 27 (i.e., prior to
          December 1, 1989), the Contractor shall ensure that an individual who
          has so certified is notified that section 27 has been reinstated.
          These certifications shall be maintained by the Contractor for a
          period of 6 years from the date a certifying employee's employment
          with the company ends or, for an agent, representative, or
          consultant, 6 years from the date such individual ceases to act on
          behalf of the Contractor.

     (e)  The certification required by paragraph (c) of this clause is a
          material representation of fact upon which reliance will be placed in
          executing this modification.

d. FAR Clause 52.215-42  REQUIREMENTS FOR COST OR PRICING DATA OR INFORMATION
                         OTHER THAN COST OR PRICING DATA--MODIFICATIONS
                         (OCTOBER 1995)

     (a)  EXCEPTIONS FROM COST OR PRICING DATA.

          (1)  In lieu of submitting cost or pricing data for modifications
               under this contract, for price adjustments expected to exceed
               the threshold set forth at FAR 15.804-2(a)(1) on the date of the
               agreement on price or the date of the award, whichever is later,
               the Contractor may submit a written request for exception by
               submitting the information described in the following
               subparagraphs.  The Contracting Officer may require additional
               supporting information, but only to the extent necessary to
               determine whether an exception should be granted, and whether
               the price is fair and reasonable-

           (i) Information relative to an exception granted for prior or 
               repetitive acquisitions.

          (ii) Catalog price information as follows:

               (A)  Attach a copy of or identify the catalog and its date, or
                    the appropriate pages for the offered items, or a statement
                    that the catalog is on file in the buying office to which
                    this proposal is being made.

               (B)  Provide a copy or describe current discount policies and
                    price lists (published or unpublished), e.g., wholesale,
                    original equipment manufacturer, and reseller.

               (C)  Additionally, for each catalog item that exceeds _________*
                    (extended value not unit price), provide evidence of
                    substantial sales to the general public.  This may include
                    sales order, contract, shipment, invoice, actual recorded
                    sales or other records that are verifiable.  In addition,
                    if the basis of the price proposal is sales of essentially
                    the same commercial item by affiliates, other manufacturers
                    or vendors, those sales may be included.  The offeror shall
                    explain the basis of each offered price and its
                    relationship to the established catalog price.  When
                    substantial general public sales have also been made at
                    prices other than catalog or price list prices, the offeror
                    shall indicate how the proposed price relates to the price
                    of such recent sales in quantities similar to the proposed
                    quantities.

                    * Insert dollar amount for sampling (see 15.804-1(c)(1)).

          (iii) Market price information.  Include the source and date or
                period  of the market quotation or other basis for market
                price, the  base amount, and applicable discounts.  The nature
                of the market  should be described.  The supply or service
                being purchased  should be the same as or similar to the market
                price supply or  service.  Data supporting substantial sales to
                the general  public is also required.

           (iv) Identification of the law or regulation establishing the price
                offered.  If the price is controlled under law by periodic
                rulings, reviews, or similar actions of a governmental body,
                attach a copy of the controlling document, unless it was
                previously submitted to the contracting office.

           (v)  Information on modifications of contracts or subcontracts for
                commercial items.

               (A)  If (1) The original contract or subcontract was granted an
                    exception from cost or pricing data requirements because
                    the price agreed upon was based on adequate price
                    competition, catalog or market prices of commercial items,
                    or prices set by law or regulation; and (2) the
                    modification (to the contract or subcontract) is not
                    exempted based on one of these exceptions, then the
                    Contractor may provide information to establish that the
                    modification would not change the contract or subcontract
                    from a contract or subcontract for the acquisition of a
                    commercial item to a contract or subcontract for the
                    acquisition of an item other than a commercial item.

                                                       Contract No. NO1-CP-62601


               (B)  For a commercial item exception, the Contractor may provide
                    information on prices at which the same item or similar
                    items have been sold in the commercial market.

          (2)  The Contractor grants the Contracting Officer or an authorized
               representative the right to examine, at any time before award, 
               books, records, documents, or other directly pertinent records 
               to verify any request for an exception under this clause, and 
               the reasonableness of price.  Access does not extend to cost or
               profit information or other data relevant solely to the 
               Contractor's determination of the prices to be offered in the 
               catalog or marketplace.

          (3)  By submitting information to qualify for an exception, an 
               offeror is not representing that this is the only exception 
               that may apply.

     (b)  REQUIREMENTS FOR COST OR PRICING DATA.  If the Contractor is not 
          granted an exception from the requirement to submit cost or pricing 
          data, the following applies:

          (1)  The Contractor shall submit cost or pricing data on Standard Form
               (SF) 1411, Contract Pricing Proposal Cover Sheet (Cost or 
               Pricing Data Required), with supporting attachments prepared in 
               accordance with Table 15-2 of FAR 15.804-6(b)(2).

          (2)  As soon as practicable after agreement on price, but before award
               (except for unpriced actions), the Contractor shall submit a
               Certificate of Current Cost or Pricing Data, as prescribed by FAR
               15.804-4.

                                (End of clause.)


e.   FAR Clause 52.242-3 PENALTIES FOR UNALLOWABLE COSTS (OCTOBER 1995)

     (a)  Definition.  Proposal, as used in this clause, means either- 

          (1)  A final indirect cost rate proposal submitted by the Contractor 
               after the expiration of its fiscal year which-

               (i)  Relates to any payment made on the basis of billing rates;
                    or

               (ii) Will be used in negotiating the final contract price; or

          (2)  The final statement of costs incurred and estimated to be
               incurred under the Incentive Price Revision clause (if
               applicable), which is used to establish the final contract
               price.

     (b)  Contractors which include unallowable indirect costs in a proposal
          may be subject to penalties.  The penalties are prescribed in 10
          U.S.C. 2324 or 41 U.S.C. 256, as applicable, which is implemented in
          Section 42.709 of the Federal Acquisition Regulation (FAR).

     (c)  The Contractor shall not include in any proposal any cost which is
          unallowable, as defined in Part 31 of the FAR, or an executive agency
          supplement to Part 31 of the FAR.

     (d)  If the Contracting Officer determines that a cost submitted by the
          Contractor in its proposal is expressly unallowable under a cost
          principle in the FAR, or an executive agency supplement to the FAR,
          that defines the allowability of specific selected costs, the
          Contractor shall be assessed a penalty equal to- 

          (1)   The amount of the disallowed cost allocated to this contract; 
                plus

                                                       Contract No. NO1-CP-62601

          (2)  Simple interest, to be computed-

               (i)  On the amount the Contractor was paid (whether as a
                    progress or billing payment) in excess of the amount to
                    which the Contractor was entitled; and

               (ii) Using the applicable rate effective for each six-month
                    interval prescribed by the Secretary of the Treasury
                    pursuant to Pub. L. 92-41 (85 Stat. 97).

     (e)  If the Contracting Officer determines that a cost submitted by the
          Contractor in its proposal includes a cost previously determined to
          be unallowable for that Contractor, then the Contractor will be
          assessed a penalty in an amount equal to two times the amount of the
          disallowed cost allocated to this contract.

     (f)  Determinations under paragraphs (d) and (e) of this clause are final
          decisions within the meaning of the Contract Disputes Act of 1978 (41
          U.S.C. 601, et seq.).

     (g)  Pursuant to the criteria in FAR 42.709-5, the Contracting Officer may
          waive the penalties in paragraph (d) or (e) of this clause.

     (h)  Payment by the Contractor of any penalty assessed under this clause
          does not constitute repayment to the Government of any unallowable
          cost which has been paid by the Government to the Contractor.

f.   FAR Clause 52.242-4 CERTIFICATION OF INDIRECT COSTS (OCTOBER 1995)

     (a)  The Contractor shall-

          (1)  Certify any proposal to establish or modify billing rates or to
               establish final indirect cost rates;

          (2)  Use the format in paragraph (c) of this clause to certify; and

          (3)  Have the certificate signed by an individual of the Contractor's
               organization at a level no lower than a vice president or chief
               financial officer of the business segment of the Contractor that
               submits the proposal.

     (b)  Failure by the Contractor to submit a signed certificate, as
          described in this clause, shall result in payment of indirect costs
          at rates unilaterally established by the Government.

     (c)  The certificate of indirect costs shall read as follows:

                         CERTIFICATE OF INDIRECT COSTS

          This is to Certify that to the best of my knowledge and belief:

          1.   I have reviewed this indirect cost proposal;

          2.   All costs included in this proposal (identify proposal and date)
               to establish billing or final indirect costs rates for (identify
               period covered by rate) are allowable in accordance with the
               requirements of contracts to which they apply and with the cost
               principles of the Federal Acquisition Regulation (FAR) and its
               supplements applicable to those contracts;

          3.   This proposal does not include any costs which are unallowable
               under applicable cost principles of the FAR or its supplements,
               including, but not limited to: advertising and public relations
               costs, contributions and donations, entertainment costs, fines
               and penalties, lobbying costs, defense of fraud proceedings, and
               goodwill; and

          4.   All costs included in this proposal are properly allocable to
               Government contracts on the basis of a beneficial or causal
               relationship between the expenses incurred and the contracts to
               which they are allocated in accordance with applicable
               acquisition regulations.

          I declare under penalty of perjury that the foregoing is true and
          correct.
