ITEM 1.   FINANCIAL STATEMENTS (CONTINUED)
          --------------------            

SYNBIOTICS CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

NOTE 1 - INTERIM FINANCIAL STATEMENTS:

The accompanying consolidated balance sheet as of March 31, 1999 and the
consolidated statements of operations and comprehensive income and of cash flows
for the three month periods ended March 31, 1999 and 1998 have been prepared by
Synbiotics Corporation (the "Company") and have not been audited. The
consolidated financial statements of the Company include the accounts of its
wholly-owned subsidiary Synbiotics Europe SAS. All significant intercompany
transactions and accounts have been eliminated in consolidation. These financial
statements, in the opinion of management, include all adjustments (consisting
only of normal recurring accruals) necessary for a fair presentation of the
financial position, results of operations and cash flows for all periods
presented. The financial statements should be read in conjunction with the
financial statements and notes thereto included in the Company's Annual Report
on Form 10-KSB filed for the year ended December 31, 1998. Interim operating
results are not necessarily indicative of operating results for the full year.

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.


NOTE 2 - EXTRAORDINARY ITEM:

In February 1999, the Company repaid the $1,000,000 note issued in conjunction
with the March 1998 acquisition of Prisma Acquisition Corp., which was due in
March 1999, for $800,000.  As a result, the Company recognized a $200,000
extraordinary gain upon early extinguishment of the debt, which was recorded net
of income taxes totalling $84,000.


NOTE 3 - INVENTORIES:

Inventories consist of the following:

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION
          ---------------------------------------------------------

The information contained in this Management's Discussion and Analysis or Plan
of Operation and elsewhere in this Quarterly Report on Form 10-QSB contains both
historical financial information and forward-looking statements.  Synbiotics
does not provide forecasts of future financial performance.  While management is
optimistic about the Company's long-term prospects, the historical financial
information may not be indicative of future financial performance.  In fact,
future financial performance may be materially different than the historical
financial information presented herein.  Moreover, the forward-looking
statements about future business or future results of operations are subject to
significant uncertainties and risks, which could cause actual future results to
differ materially from what is suggested by the forward-looking information.
The following risk factors should be considered in evaluating the Company's
forward-looking statements:

No Assurance that Acquired Businesses Can Be Successfully Combined
- ------------------------------------------------------------------

There can be no assurance that the anticipated benefits of the 1998 acquisition
of Prisma Acquisition Corp. ("Prisma"), the 1997 acquisition of the veterinary
diagnostics business of Synbiotics Europe SAS ("SBIO-E"), the 1996 acquisition
of the business of International Canine Genetics, Inc. ("ICG"),  or any other
future acquisitions (collectively, the "Acquired Business") will be realized.
Acquisitions of businesses involve numerous risks, including difficulties in the
assimilation of the operations, technologies and products of the Acquired
Business, introduction of different distribution channels, potentially dilutive
issuances of equity and/or increases in leverage and risk resulting from
issuances of debt securities, the need to establish internally operating
functions which had been previously provided pre-acquisition by a corporate
parent, accounting charges, operating companies in different geographic
locations with different cultures, the potential loss of key employees of the
Acquired Business, the diversion of management's attention from other business
concerns and the risks of entering markets in which Synbiotics has no or limited
direct prior experience.  In addition, there can be no assurance that the
acquisitions will not have a material adverse effect upon Synbiotics' business,
results of operations or financial condition, particularly in the quarters
immediately following the consummation of the acquisition, due to operational
disruptions, unexpected expenses and accounting charges which may be associated
with the integration of the Acquired Business and Synbiotics, as well as
operating and development expenses inherent in the Acquired Business itself as
opposed to integration of the Acquired Business.

Competition
- -----------

Many competitors, such as Pfizer Animal Health, Merial Animal Health (the
successor to Rhone Merieux), Schering-Plough and IDEXX Laboratories, have
substantially greater financial, manufacturing, marketing and product research
resources than the Company.  Large companies in particular have extensive
expertise in conducting pre-clinical and clinical testing of new products and in
obtaining the necessary regulatory approvals to market products.  Competition is
based on test sensitivity, accuracy and speed; product price; and similar
factors.  IDEXX Laboratories requires its distributors not to carry the products
of competitors such as Synbiotics.  Competition in the animal health care
industry is intense, and is particularly intense in vaccines.  There can be no
assurance that such competition will not adversely affect Synbiotics' results of
operations or ability to maintain or increase sales and market share.

History of Operating Losses; Accumulated Deficit
- ------------------------------------------------

Although the Company's operations were profitable for the years ended December
31, 1997 and 1996, the Company has had a history of losses.  Due to the
settlement with Barnes-Jewish Hospital of St. Louis (the "Hospital"), the
Company incurred a loss of $1,911,000 for 1998.  Synbiotics has incurred a
consolidated accumulated deficit of $10,321,000 at March 31, 1999, even after
the release in 1996 of a $7,158,000 valuation allowance related to deferred tax
assets.

                                      -10-

 
Reliance on Third Party Manufacturers
- -------------------------------------

Certain of Synbiotics' products (including its ICT Gold(TM), VetRED(R) and
WITNESS(R) diagnostic kits and all of its vaccines) are, and certain anticipated
new products are expected to be, manufactured by third parties under the terms
of distribution and/or manufacturing agreements. The ICT Gold, VetRED(R) and
WITNESS(R) products and feline leukemia virus vaccine are licensed to Synbiotics
by their respective outside manufacturers. In the event that these third parties
are unable (due to operational, licensing, financial or other reasons) to supply
Synbiotics with sufficient finished products capable of being sold in
Synbiotics' markets, Synbiotics would suffer significant disruption of its
business. Synbiotics has the right, under certain circumstances, pursuant to the
agreements to use alternate manufacturing sources. In some circumstances,
however, the Company would lack such a right.

In November 1998, Bio-Trends International, Inc. ("Bio-Trends"), Synbiotics'
supplier of feline leukemia virus ("FeLV") vaccine, declared Synbiotics'
previously exclusive worldwide rights to the vaccine to be non-exclusive, based
on an alleged insufficiency of marketing expenditures by Synbiotics.  Synbiotics
has filed an arbitration action against Bio-Trends, seeking a declaration that
its rights remain exclusive.  An arbitrator has scheduled the hearing in the
action for May 1999.  In addition, in February 1999, Binax, Inc. ("Binax"), the
licensor and manufacturer of the ICT Gold products, purported to invoke a
contract clause, based on number of products marketed, which could conceivably
result in Synbiotics losing the right to sell the products.  Synbiotics has
denied that Binax is entitled to invoke the clause, but has entered into
negotiations with Binax regarding the reversion of certain license rights.  In
the event that Synbiotics were to lose its right to sell these products,
management believes that the Company would be able to replace most of the lost
sales with sales of its other canine heartworm diagnostic and FeLV diagnostic
products.  Binax has indicated that it does not propose to deprive Synbiotics of
the right to sell the ICT Gold(TM) canine heartworm diagnostic product.

In addition, Synbiotics' sales of FeLV vaccine to Merial Animal Health and other
distributors for resale in Europe will be at risk unless Bio-Trends obtains
European Union regulatory approvals for its manufacturing facilities.  Loss of
these sales would have a material adverse effect on Synbiotics' profitability.

If Synbiotics should encounter delays or difficulties in its relationships with
manufacturers, the resulting problems could have a material adverse effect on
Synbiotics.  In fact, all of the Company's vaccine products (exclusive of its
FeLV and canine corona virus vaccine products) are manufactured using bulk
antigen fluids that have been supplied by a third party.  The supply agreement
has expired and the Company has been unable to locate a replacement supplier for
these bulk antigen fluids.  The Company has decided to discontinue the sales of
the affected products once its remaining supplies have been exhausted, which the
Company believes will be during the second quarter of 1999.  Sales of the
affected products totalled $2,073,000, $1,596,000 and $1,225,000 during 1998,
1997 and 1996, respectively.

Sales and Marketing
- -------------------

The Company's product distribution strategy results in a large percentage of
sales being to only a few customers.  During the year ended December 31, 1998,
sales to two distributors totalled 33% of the Company's net sales.    One of
these distributors is a co-op with which Synbiotics ceased doing business in the
second quarter of 1999.  In addition, SBIO-E's small animal products are
presently sold primarily through distributors (although the Company is expanding
its telesales and direct sales capabilities), while its large animal products
are sold directly to laboratories.  (Small animals mean pet dogs and cats; large
animals mean farm animals.)  There can be no assurance that Synbiotics will be
able to establish an adequate sales and marketing capability in any or all
targeted markets or that it will be successful in gaining market acceptance of
its products.  To the extent Synbiotics enters into distributor arrangements,
any revenues received by Synbiotics will be dependent on the efforts of third
parties and there can be no assurance that such efforts will be successful.
IDEXX Laboratories' requirement that its distributors not carry the products of
competitors such as Synbiotics has induced certain distributors to stop doing
business with Synbiotics in order to carry IDEXX products instead.  Synbiotics
adopted a somewhat similar policy in the second quarter of

                                      -11-

 
1999, which caused some distributors to abandon the Synbiotics product line.  In
addition, Synbiotics' sales of products, on a private-label basis, toward the
over-the-counter market may cause an adverse reaction among Synbiotics' regular
distributor and veterinarian customers.

Attraction of Key Employees
- ---------------------------

The success of Synbiotics depends, in part, on its ability to retain highly
qualified personnel, including senior management and scientific personnel.
Competition for such personnel is intense and the inability to retain additional
key employees or the loss of one or more current key employees could adversely
affect Synbiotics.  Although Synbiotics has been successful in retaining
required personnel to date, there can be no assurance that Synbiotics will be
successful in the future.

Reliance on New and Recent Products
- -----------------------------------

Synbiotics relies to a significant extent on new and recently developed
products, and expects that it will need to continue to introduce new products to
be successful in the future. There can be no assurance that Synbiotics will
obtain and maintain market acceptance of its products. With respect to future
products, there can be no assurance that such products will meet applicable
regulatory standards, be capable of being produced in commercial quantities at
acceptable cost or be successfully commercialized.

There can be no assurance that new products can be manufactured at a cost or in
quantities necessary to make them commercially viable.  If Synbiotics were
unable to produce internally, or to contract for, a sufficient supply of its new
products on acceptable terms, or if it should encounter delays or difficulties
in its relationships with manufacturers, the introduction of new products would
be delayed, which could have a material adverse effect on  Synbiotics.

Future Capital Needs; Uncertainty of Additional Funding
- -------------------------------------------------------

The development and commercialization of Synbiotics' products require
substantial funds.  Synbiotics' future capital requirements will depend on many
factors, including cash flow from operations, the need to finance further
acquisitions, if any, continued scientific progress in its products and
development programs, the cost of manufacturing scale-up, the costs involved in
preparing, filing, prosecuting, maintaining and enforcing patent claims, the
cost involved in patent infringement litigation, competing technological and
market developments, and the cost of establishing effective sales and marketing
arrangements.  Synbiotics anticipates that its existing, available cash, cash
equivalents and short-term investments will be adequate to satisfy its current
capital requirements and fund its current operations, although any large
acquisition would require additional capital resources.  There can be no
assurance that additional financing, if required, will be available on
acceptable terms or at all.  If additional funds are raised by issuing equity
securities, further dilution to then existing shareholders may result. Debt
financing would result in increased leverage and risk.

In July 1997, the Company obtained $15,000,000 of debt financing from Banque
Paribas, of which $11,493,000 was used in connection with the acquisition of
SBIO-E.  The $15,000,000 included a $5,000,000 revolving line of credit.
However, draws on the line of credit are subject to certain requirements and can
be used only for certain purposes.  Additionally, Banque Paribas requires the
Company to maintain certain financial ratios and levels of tangible net worth
and also restricts the Company's ability to pay dividends and make loans,
capital expenditures or investments without the Bank's consent.  Through March
31, 1999, the Company had repaid $1,750,000 of principal on the loans and had an
outstanding principal balance on the loans of $8,250,000 as of March 31, 1999.

                                      -12-

 
Seasonality
- -----------

The Company's operations have become seasonal due to the success of its canine
heartworm diagnostic products.  Sales and profits tend to be concentrated in the
first half of the year, as distributors prepare for the heartworm season by
purchasing diagnostic products for resale to veterinarians.  This seasonality
has been somewhat reduced by the SBIO-E operations, which is relatively less
seasonal.  Increased sales of the Prisma instruments and supplies would also
reduce seasonality.

Patents and Proprietary Technology
- ----------------------------------

Synbiotics generally has sought and will continue to seek to protect its
interests by treating its particular variations in the production of monoclonal
antibodies as trade secrets.  Synbiotics also has pursued and intends to
continue aggressively to pursue protection for new products, new methodological
concepts, and compositions of matter through the use of patents where
obtainable.  At present, Synbiotics has been granted eleven U.S. patents and has
three U.S. patents pending..

There can be no assurance that Synbiotics will be issued any additional patents
or that, if any patents are issued, they will provide Synbiotics with
significant protection or will not be challenged.  Even if such patents are
enforceable, Synbiotics anticipates that any attempt to enforce its patents
would be time consuming and costly.  Synbiotics is currently suing Heska
Corporation ("Heska") for infringing Synbiotics' canine heartworm patent, and
Heska has countersued seeking to invalidate the patent.  In the event that
Synbiotics were to lose its lawsuit against Heska, management believes its only
direct liability would be its out-of-pocket legal expenses.  Although Heska's
counterclaim does not include a claim for damages, if Synbiotics were to lose on
Heska's counterclaim, the Company could face additional competition for its
canine heartworm diagnostic products as other third parties would be able to
manufacture products incorporating Synbiotics' patented technology.  Moreover,
the laws of some foreign countries do not protect Synbiotics' proprietary rights
in its products to the same extent as do the laws of the United States.

The patent positions of biotechnology companies, including Synbiotics, are
uncertain and involve complex legal and factual issues.  Additionally, the
coverage claimed in a patent application can be significantly reduced before the
patent is issued.  As a consequence, there can be no assurance that any of
Synbiotics' future patent applications will result in the issuance of patents
or, if any patents issue, that they will provide significant proprietary
protection or will not be circumvented or invalidated.  Because patent
applications in the United States are maintained in secrecy until patents issue
and publication of discoveries in the scientific or patent literature often lag
behind actual discoveries, Synbiotics cannot be certain that it was the first
inventor of inventions covered by its pending patent applications or that it was
the first to file patent applications for such inventions.  Moreover, Synbiotics
may have to participate in interference proceedings declared by the U.S. Patent
and Trademark Office to determine priority of invention that could result in
substantial cost to Synbiotics, even if the eventual outcome is favorable to
Synbiotics.  There can be no assurance that Synbiotics' patents would be held
valid by a court of competent jurisdiction.  An adverse outcome of any patent
litigation based on third parties' patents could subject Synbiotics to
significant liabilities to third parties, require disputed rights to be licensed
from or to third parties or require Synbiotics to cease using the technology in
dispute.

In October 1997, the Hospital filed a lawsuit against the Company claiming that
the Company infringed a patent owned by the Hospital which covers the Company's
canine heartworm diagnostic products.  On July 28, 1998, the Company entered
into a settlement agreement with the Hospital calling for the Company to pay the
Hospital or its affiliates $1,600,000 in cash, 333,000 shares of the Company's
common stock, and undisclosed future payments and royalties.  The Company
recorded a one-time pre-tax charge of approximately $3,922,000 and reclassified
$678,000 of legal expenses related to the patent litigation from general and
administrative expenses in the year ended December 31, 1998.

                                      -13-

 
There can be no assurance that other third parties will not assert other
infringement claims against Synbiotics in the future or that any such assertions
will not result in costly litigation or require Synbiotics to obtain a license
to intellectual property rights of such parties.  There can be no assurance that
any such licenses would be available on terms acceptable to Synbiotics, if at
all.  Furthermore, parties making such claims may be able to obtain injunctive
or other equitable relief that could effectively block Synbiotics' ability to
further develop, or commercialize, its products in the United States and abroad.
Such claims could also result in the award of substantial damages.  Finally,
litigation, regardless of outcome, could result in substantial cost to, and a
diversion of efforts by, Synbiotics.

Government Regulation
- ---------------------

Synbiotics' business is subject to substantial regulation by the United States
government, most notably the United States Department of Agriculture, and
France.  In addition, Synbiotics' operations may be subject to future
legislation and/or rules issued by domestic or foreign governmental agencies
with regulatory authority relating to Synbiotics' business.  There can be no
assurance that Synbiotics will be found in compliance with any of the various
regulations to which it is subject.

For marketing outside the United States, Synbiotics and its suppliers are
subject to foreign regulatory requirements in such foreign jurisdictions, which
vary widely from country to country.  There can be no assurance that Synbiotics
and its suppliers will meet and sustain compliance with any such requirements.
In particular, Synbiotics' sales of feline leukemia virus vaccine to Merial
Animal Health and other distributors for resale in Europe will be at risk unless
Bio-Trends, our supplier, obtains European Union regulatory approvals for its
manufacturing facilities.

Product Liability and Insurance
- -------------------------------

The design, development and manufacture of Synbiotics' products involve an
inherent risk of product liability claims and associated adverse publicity.
Synbiotics has obtained liability insurance for potential product liability
associated with the commercial sale of its products.  There can be no assurance,
however, that Synbiotics will be able to obtain or maintain such insurance.
Although Synbiotics currently maintains general liability insurance, there can
be no assurance that the coverage limits of Synbiotics' insurance policies will
be adequate.

Hazardous Materials
- -------------------

Synbiotics' manufacturing and research and development processes involve the
controlled use of hazardous materials, chemicals and various radioactive
compounds.  Although Synbiotics believes that its safety procedures for handling
and disposing of such materials comply with the standards prescribed by local
state and federal regulations, the risk of accidental contamination or injury
from these materials cannot be completely eliminated.  In the event of such an
accident, Synbiotics could be held liable for any damages that result and any
such liability could exceed the resources of Synbiotics.  Synbiotics may incur
substantial costs to comply with environmental regulations.

RESULTS OF OPERATIONS

Net sales for the first quarter of 1999 increased by $589,000 or 7% over the
first quarter of 1998. The increase in net sales is due to a net increase in the
overall sales of diagnostic products of $440,000 and an increase in vaccine
product sales of $149,000. The increase in the sales of diagnostic products is
due to an increase in canine heartworm diagnostics sales of 9% and an increase
in feline diagnostics sales of 8%. The increased canine heartworm diagnostics
sales were due to increases in the sales of rapid canine heartworm diagnostic
tests, resulting from the success of the Company's WITNESS(R) product (which was
introduced in the U.S. in the third quarter of 1998), and further increases in
DiroCHEK(R) sales; however, the Company's sales of its canine heartworm
diagnostic products have been impacted by increased competition. The increase in
feline diagnostic sales was due to a full quarter of sales of the Company's
WITNESS(R) FeLV diagnostic test which was introduced at the end of the first
quarter of 1998, offset by a decrease in the sales of the Company's feline
heartworm diagnostic test which was launched in the

                                      -14-

 
first quarter of 1998.  The increase in companion animal diagnostic sales was
offset by decreases in large animal diagnostic sales for SBIO-E of 14% due to
the non-recurrence of one-time sales in the first quarter of 1998 relating to
the changing of distribution partners.  These one-time sales of approximately
$800,000 in the first quarter of 1998 were also at reduced prices which
negatively impacted gross margins during the first quarter of 1998.  The
increased vaccine sales reflected an increase of 69% in sales of bulk FeLV
vaccine (related to the timing of shipments as requested by Merial Animal
Health, our OEM customer), offset by a 6% decrease in sales of vaccines to
private label partners.  The Company's instrument business, which was acquired
in March 1998, contributed 3% of sales for the first quarter of 1999.

Overall, net sales in countries other than the U.S. and France in the first
quarter of 1999 increased by $758,000 or 84% over the first quarter of 1998,
reflecting the transition of SBIO-E's strategy from distribution to direct
sales.

All of the Company's vaccine products (exclusive of its FeLV and canine corona
virus vaccine products) are manufactured using bulk antigen fluids that have
been supplied by a third party.  The supply agreement has expired and the
Company has been unable to locate a replacement supplier for these bulk antigen
fluids.  The Company has decided to discontinue the sales of the affected
products once its remaining supplies have been exhausted, which the Company
believes will be during the second quarter of 1999.  Sales of the affected
products totalled $2,073,000 and $1,596,000 during 1998 and 1997, respectively.

The cost of sales as a percentage of net sales was 43% during the first quarter
of 1999 compared to 46% during the first quarter of 1998 (i.e., gross margin
increased to 57% from 54%).  The higher gross margin is a direct result of two
factors: i) a high percentage of SBIO-E's sales relate to products manufactured
by SBIO-E rather than by third party manufacturers and ii) SBIO-E's sales of its
large animal diagnostic products during the first quarter of 1999 carried higher
margins than those during the first quarter of 1998 as a result of one-time
sales in the first quarter of 1998, relating to the changing of distribution
partners, of approximately $800,000 which were at reduced prices and which
negatively impacted gross margins. The Company's domestic sales (i.e., exclusive
of the SBIO-E sales), during the first quarter of 1999 and 1998 had a 56% gross
margin. A significant portion of the Company's manufacturing costs are fixed
costs. Among the Company's major products, DiroCHEK(R) canine heartworm
diagnostic products are manufactured at Company facilities, whereas WITNESS(R),
ICT GOLD HW, VetRED(R) and all vaccines are manufactured by third parties. In
addition to affecting gross margins, outsourcing of manufacturing renders the
Company relatively more dependent on the third-party manufacturers.

In March 1999, the Company amended (effective July 1, 1998) its FeLV vaccine
supply agreement with Merial.  Since 1992, Synbiotics has supplied Bio-Trends-
manufactured FeLV vaccine to Merial in the United States.  This has included
shipments to Merial at Synbiotics' cost, while Merial has paid a royalty to
Synbiotics on Merial's sales of Merial-labeled FeLV vaccine.  In exchange for
$1,500,000 in cash (which the Company recorded as a one-time license fee in the
first quarter of 1999), the revised supply agreement broadens Merial U.S.
distribution rights (which had been an area of ongoing discussions) and
eliminates the royalty.  In addition, the Company and Merial will seek to have
Bio-Trends supply FeLV vaccine directly to Merial for U.S. distribution.  The
FeLV vaccine sales to Merial for U.S. resale totalled $2,029,000 and $1,309,000
during 1998 and 1997, respectively.  If Merial buys its FeLV vaccine for U.S.
resale from Bio-Trends instead of from Synbiotics, Synbiotics will lose net
sales but have a relatively higher overall gross margin.  In the meantime,
Synbiotics will continue to resell Bio-Trends-supplied FeLV vaccine to Merial at
cost for U.S. resale.  Synbiotics' sales of its own VacSyn and other FeLV-
labeled vaccine products, its sales of Bio-Trends supplied FeLV vaccine to
Merial S.A. in France, which are at a profit rather than at cost, and the
collaborative research relationship between Merial Limited and Synbiotics are
not affected by this amendment.

Research and development expenses during the first quarter of 1999 increased
$39,000 or 7% over the first quarter of 1998.  The increase is primarily due to
an increase in personnel costs resulting from the March 1998 acquisition of
Prisma, offset by a decrease in external research and development projects.
Research and development expenses as a percentage of net sales were 6% during
the first quarters of 1999 and 1998.  The Company expects its research

                                      -15-

 
and development expenses to increase during the remainder of 1999 due to further
development of Prisma's product line.

Selling and marketing expenses during the first quarter of 1999 increased by
$427,000 or 27% over the first quarter of 1998.    The increase is due primarily
to the addition of an outbound telemarketing group during the third quarter of
1998, increased royalties due to the 1998 introduction of the WITNESS/(R)/
products, an increase in the field sales force during the fourth quarter of 1998
and an increase in promotional programs.  Selling and marketing expenses as a
percentage of net sales were 21% and 18% during the first quarter of 1999 and
1998, respectively.

The Company has experienced increased competition in certain of its U.S.
distribution channels.  In addition to the previously announced patent
infringement lawsuit, the Company has significantly revised some of its
distribution strategies and policies, arising primarily from Heska's attempt to
launch a canine heartworm diagnostic product, and continues to increase its own
marketing capabilities.  The Company will continue to increase its investment in
sales and marketing to expand its field sales force, its telemarketing effort.
Sales to U.S. distributors accounted for 33%, 47% and 50% of first quarter net
sales during 1999, 1998 and 1997, respectively.  In the second quarter of 1999,
the Company decided to require its full-line distributors to carry its heartworm
diagnostics exclusively.  As a result of this policy, the Company and several of
its U.S. distributors terminated their relationship in the second quarter of
1999.  The Company believes that its remaining exclusive distributors, coupled
with its own marketing efforts, may be able to substantially mitigate the sales
lost from the terminated distribution arrangements.

General and administrative expenses during the first quarter of 1999 increased
by $175,000 or 14% over the first quarter of 1998.  The increase is due
primarily to an increase in personnel costs resulting from the March 1998
acquisition of Prisma.  General and administrative expenses as a percentage of
net sales were 15% during the first quarters of 1999 and 1998.

Royalty income during the first quarter of 1999 decreased $71,000 or 96% from
the first quarter of 1999.  As a result of the amended supply agreement with
Merial (see above), the Company will no longer receive royalties beginning in
1999.  Royalty income totalled $317,000 and $332,000 during 1998 and 1997,
respectively.

Net interest expense during the first quarter of 1999 increased by $69,000 over
the first quarter 1998 due to a higher number of days of interest expense
related to the debt incurred to a form stockholder of Prisma and  increasing
amortization of debt issuance costs and debt discount, incurred in conjunction
with the acquisition of SBIO-E.

The combined effective tax rate was 44% during the first quarter of 1999 as
compared to 43% during the first quarter of 1998.  The increase in the effective
rate is due primarily to an increase in state income tax expense resulting from
certain states' taxes being calculated on net worth rather than net income.

FINANCIAL CONDITION

Management believes that the Company's present capital resources, which included
working capital of $11,524,000 at March 31, 1999, are sufficient to meet its
current working capital needs and service the debt related to the acquisition of
SBIO-E through 1999.  However, pursuant to a debt agreement with Banque Paribas,
the Company is required to maintain certain financial ratios and levels of
tangible net worth and is also restricted in its ability to pay dividends and
make loans, capital expenditures or investments without Banque Paribas' consent.
As of March 31, 1999, the Company had outstanding principal balances on its
Banque Paribas debt of $8,250,000, and may borrow up to $5,000,000 (subject to a
borrowing base calculation) on its revolving line of credit.  In February 1999,
the Company repaid the $1,000,000 note issued in conjunction with the
acquisition of Prisma for $800,000, and recognized a $200,000 extraordinary
gain, which was recorded, net of income taxes totalling $84,000, during the
first quarter of 1999.

                                      -16-

 
The Company's operations have become seasonal due to the success of its canine
heartworm diagnostic products.  Sales and profits tend to be concentrated in the
first half of the year, as distributors prepare for the heartworm season by
purchasing diagnostic products for resale to veterinarians.  This seasonality
has been somewhat reduced by the SBIO-E operations, which are relatively less
seasonal.  Increased sales of the Prisma instruments and supplies would also
reduce seasonality.

Impact of the Year 2000 Issue
- -----------------------------

The year 2000 issue is the result of computer programs being written using two
digits rather than four digits to define the applicable year.  Any of the
Company's embedded microprocessors or computer programs that have date-sensitive
software may recognize a date using "00" as the year 1900 rather than the year
2000.  This could result in a system failure or miscalculation causing
disruptions of operations, including, among other things, a temporary inability
to process transactions, send invoices or engage in similar normal business
activities.

The Company has determined that the financial systems used in its U.S.
operations are not year 2000 compliant.  Although the software manufacturer has
provided the necessary software to make the systems year 2000 compliant, the
Company has also determined that its current information system is inadequate to
meet its growth goals and objectives.  The Company selected an enterprise
resource planning system, and began implementation of the new system in March
1999. The total cost of the new system (including software, hardware and
implementation) is expected to be approximately $1,000,000, for which the
Company has obtained lease financing.  The new system is year 2000 compliant.

The computer systems of SBIO-E are not affected by the year 2000 issue as new
systems were implemented during 1999, and those systems are year 2000 compliant.
The Company has also determined that its telephone systems and equipment used in
its manufacturing and research and development processes are year 2000
compliant.

The Company is currently in the process of determining the year 2000 compliance
status of its major suppliers and customers.  The Company has sent letters
requesting the status of the suppliers' and customers' year 2000 compliance, and
has yet to receive any responses.  In the event that these suppliers and
customers fail to become year 2000 compliant and suffer disruptions in their own
operations, there could be a material adverse impact on the Company's results of
operations and financial condition beginning in 2000.  The greatest disruption
would occur if third-party manufacturers of Synbiotics' diagnostic products and
vaccines were interrupted due to their own, or their own suppliers', year 2000
problems.
