                                     PART I
                                     ------

ITEM 1.   BUSINESS
          --------

GENERAL

Synbiotics Corporation (the "Company") is a leading provider of rapid diagnostic
and laboratory diagnostic products for the animal health care industry.  The
Company also markets a line of vaccine products.  Synbiotics was founded in 1982
to research and develop monoclonal antibody-based diagnostic and therapeutic
products.  In the early years, the Company, like most biotechnology firms, was
focused on developing therapeutics for human diseases.  The high cost of human
drug development, coupled with the lengthy FDA approval process, motivated
Synbiotics to begin commercializing its technology through the less restrictive
animal health care market.  Synbiotics is one of a small number of companies
that focuses exclusively on animal health and is the second largest provider of
diagnostic products to the animal health market.

On July 9, 1997, the Company acquired Synbiotics Europe SAS ("SBIO-E") (formerly
Rhone Merieux Diagnostics, S.A.S.), the worldwide veterinary diagnostic business
of Rhone Merieux S.A.S. pursuant to purchase agreements dated May 14, 1997 and
amended July 9, 1997.

On October 25, 1996 the Company acquired substantially all of the assets of
International Canine Genetics, Inc. ("ICG") pursuant to a purchase agreement
dated July 23, 1996 and amended September 7, 1996.  The operations acquired from
ICG consist of the manufacturing and marketing of canine reproduction diagnostic
products and services, PennHIP/(R)/ (a diagnostic test for canine hip dysplasia)
and nutritional supplements sold to breeders and owners of purebred dogs and
their veterinarians.

Synbiotics is blending its research and development, acquisitions, and licensing
agreements with its distribution through established global channels.  The
Company's product portfolio consists of sixty-two diagnostic test kits and
detection devices, one veterinary immunotherapeutic product, and seven vaccines.
Many of its products hold strong positions in their specific markets.

On March 6, 1998, the Company acquired by merger Prisma Acquisition Corp.
("Prisma"), a privately-held company located in Rome, NY, which develops,
manufactures and markets instruments and reagents used by veterinarians to
measure blood chemistry information at the point-of-care.

BUSINESS STRATEGY

The Company's strategy is to grow from its established position in the market
through new products and technologies, expanded distribution, enhanced marketing
and acquisitions and licensing.

MARKET AND PRODUCT OVERVIEW

The Company sells its products both in the United States and in foreign
countries.  The total number of family owned dogs and cats is estimated to
exceed 100 million in the United States alone.  The Company believes that its
current and intended future products will offer veterinarians an opportunity to
improve the quality and expand the scope of veterinary health care services.

Synbiotics' most commercially successful products are its canine heartworm
diagnostics (representing 33% of 1997 sales).  The Company estimates that it has
a 25% - 30% share of the estimated $30 million U.S. heartworm

                                      -1-
<PAGE>
 
diagnostics market.  Sales in this segment have historically been strongest
during the December to April time period when distributors purchase merchandise
to sell to veterinarians for the heartworm season.

MARKETING

Synbiotics sells its products in the United States, Europe and, to a limited
extent, Latin America.  In the United States, the Company markets its line
through independent distributors which, taken together, have approximately 90
outlets, 600 field sales representatives, and 200 telemarketing representatives
covering the 25,000 veterinary clinics throughout the country.  In addition,
Synbiotics sells vaccine products to distributors, on a private label basis, for
resale to the over-the-counter market and through catalogs.  Sales to
laboratories and other centralized facilities (approximately 50 in the U.S.) are
handled directly.  Outside the United States, Synbiotics sells its small animal
products through distributors, and on an OEM basis, and its large animal
products directly to laboratories.  The Company maintains a small marketing and
sales force, and this internal staff services the sales network by training
distributor representatives, responding to technical inquiries, advertising and
promoting products through direct mail, telemarketing, and journal
advertisements, and providing other marketing support functions.  However, this
strategy results in a large percentage of sales being to only a few customers.
During the year ended December 31, 1997, sales to two distributors totalled 40%
of the Company's gross revenues.


MANUFACTURING

Synbiotics manufactures most of its products at its facilities located in San
Diego, California and Lyons, France. However, Synbiotics relies on outside
manufacturers for its ICT Gold/(TM)/, VetRED/(R)/ and WITNESS/(R)/ diagnostic
tests and for all of its vaccine products. The ICT Gold/(TM)/, VetRED/(R)/ and
WITNESS/(R)/ products and feline leukemia virus vaccine are licensed to
Synbiotics by their respective outside manufacturers.

PATENTS AND TRADE SECRETS

The Company believes that its proprietary technology is an important competitive
factor in its business, and that protection of its intellectual property rights
is a high priority.  The Company believes that the basic hybridoma (the cell
that produces the monoclonal antibody) technology is in the public domain and is
therefore not patentable.  The complex biological and chemical process, however,
is subject to numerous improvements, variations and applications of hybridoma
technology which may prove to be patentable.  Considering the difficulty of
enforcing any patent rights to such improvements, and the rapid advancements in
the field, the Company 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.  The Company 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, the Company has been granted eleven U.S. patents
and has three U.S. patents pending.

GOVERNMENT REGULATION

Most diagnostic test kits for animal health applications marketed in the U.S.
require approval by the United States Department of Agriculture ("USDA").
Germany and Japan are the only foreign countries in which the Company markets
its products that require governmental approval.  Synbiotics' semen freezing
products and ovulation timing diagnostic products for dogs fall within the
definition of devices as that term is defined in the Federal Food, Drug, and
Cosmetic Act and, therefore, may be subject to regulation by the FDA.  The
Company is also subject to additional regulation in connection with its pet food
products.

The Company's manufacturing facility in the United States is licensed by the
USDA.  The Company adheres to Good Manufacturing Practices ("GMP") standards.
The Company's SBIO-E manufacturing facility is not licensed by any foreign
regulatory agency (as there is no licensing requirement) nor by the USDA (as the
products manufactured at

                                      -2-
<PAGE>
 
the facility are not currently sold in the United States).  Should the Company
wish to sell in the U.S. the products manufactured by SBIO-E, the facility will
have to obtain a license from the USDA.

In addition to the foregoing, the Company's operations may be subject to future
legislation and/or rules issued by domestic or foreign governmental agencies
with regulatory authority relating to the Company's business.  The Company has
no reason to believe that any such future legislation and/or rules would be
materially adverse to its business.

COMPETITION

The Company believes that it is the second-leading competitor in the animal
health diagnostic market.  Most of the Company's competitors are either small
divisions of larger human health and chemical companies or smaller companies
that sell veterinary products while trying to diversify into the higher profile,
and more regulated, human health field.  The principal competitor in the
industry is IDEXX Laboratories, Inc., a publicly traded company with annual
revenues of $263,000,000 that develops, manufactures, and distributes detection
and diagnostic products for animal health, food, and environmental testing
applications.

Competition in the animal health care industry is intense.  Many competitors,
such as Pfizer Animal Health, Merial Animal Health, 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 the Company.

RESEARCH AND DEVELOPMENT

The Company spent approximately $1,692,000 and $994,000 on research and
development activities during the years ended December 31, 1997 and 1996,
respectively.  These figures include both internal research and development and
expenditures under contracts for research and development activities with
outside parties relating to certain veterinary diagnostic products which utilize
licensed technology.

EMPLOYEES

As of December 31, 1997, the Company had a total of 104 employees worldwide, all
of whom were full-time.

RAW MATERIALS

The manufacturing of diagnostics, therapeutics and vaccines requires raw
materials which generally are, and have been, readily available from several
sources.  A majority of the Company's vaccine products (exclusive of its feline
leukemia vaccine products) are manufactured using bulk antigen fluids that have
been supplied by a third party.  The supply agreement has expired and the
Company is currently seeking a replacement supplier for these fluids.  The
Company believes it has adequate levels of these bulk fluids to meet its
manufacturing requirements through the third quarter of 1998.  In the event that
the Company is unable to locate a replacement supplier, sales of the Company's
private label vaccine products, beginning in the fourth quarter of 1998, will be
materially adversely affected.


ITEM 2.   PROPERTIES
          ----------

The Company leases two buildings in San Diego, California.  The buildings
contain approximately 49,000 square feet of space, and house the Company's
corporate and sales headquarters, executive offices, research and development

                                      -3-
<PAGE>
 
laboratories and manufacturing facilities.  The Company also leases an
approximately 13,000 square foot building in Lyons, France which houses SBIO-E's
corporate and sales headquarters, executive offices, research and development
laboratories and manufacturing facilities.  Management believes that these
facilities are adequate for the Company's current level of operations.  The
Company also leases a Malvern, Pennsylvania facility for operating its
PennHIP(R) business, a sales office in Kansas City, Missouri, and, since the
Prisma acquisition, the Rome, New York facilities Prisma had occupied.


ITEM 3.   LEGAL PROCEEDINGS
          -----------------

Barnes-Jewish Hospital v. Synbiotics Corporation - United States District Court
- -------------------------------------------------------------------------------
for the Eastern District of Missouri, Eastern Division
- ------------------------------------------------------

As previously reported by Synbiotics, Barnes-Jewish Hospital of St. Louis (the
"Hospital") is the owner of a patent which the Hospital alleges covers the
Company's canine heartworm diagnostic products.  The Company is also the owner
of several patents which cover its canine heartworm diagnostic products.  The
Company believes that it does not infringe the Hospital's patent, and also
believes that the Hospital's patent is invalid.  On September 29, 1997, the
Hospital sued the Company in the United States District Court for the Eastern
District of Missouri for patent infringement, seeking unspecified damages.

The Hospital had previously sued IDEXX Laboratories, Inc., the Company's primary
competitor for canine heartworm diagnostics, for patent infringement under the
Hospital's patent; IDEXX's defense involved an assertion that the patent is
invalid.  IDEXX announced a settlement of this suit on September 28, 1997.


Item 4.   Submission of Matters to a Vote of Security Holders
          ---------------------------------------------------

None.

ITEM 5.   MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS
          --------------------------------------------------------

The Company's common stock is quoted in the Nasdaq National Market under the
symbol SBIO.  Price ranges reported are the high and low trade price information
as reported by the Nasdaq National Market.  No cash dividends have ever been
paid, and the Company does not currently anticipate paying cash dividends in the
foreseeable future.  As of March 31, 1998, there were approximately 517
shareholders of record of the Company's common stock.

ITEM 6.   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 Annual Report on Form 10-KSB 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:

Patent Litigation Involving the Company's Canine Heartworm Diagnostic Products
- ------------------------------------------------------------------------------

Barnes-Jewish Hospital of St. Louis (the "Hospital") has filed a lawsuit against
the Company claiming that the Company infringes a patent owned by the Hospital
(see Item 3 - Legal Proceedings) and is seeking unspecified damages.  As
previously reported by Synbiotics, the Hospital is the owner of a patent which
the Hospital alleges covers the Company's canine heartworm diagnostic products.
The Company is also the owner of several patents which cover its canine
heartworm diagnostic products.  The Company believes that it does not infringe
the Hospital's patent, and also believes that the Hospital's patent is invalid.
However, in the event that the Company were to lose the lawsuit or enter into an
unfavorable settlement agreement, there would be a materially adverse effect on
the Company's financial condition and results of operations.  In addition,
patent litigation is likely to be costly and disruptive even if the Company were
to prevail in the litigation.

The Hospital had previously sued IDEXX Laboratories, Inc., the Company's primary
competitor for canine heartworm diagnostics, for patent infringement under the
Hospital's patent; IDEXX's defense involved an assertion that the patent is
invalid.  On September 28, 1997, IDEXX announced a settlement of this suit for
$5,500,000 (an undisclosed portion of which represents royalties on prior sales)
and future royalties.

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

There can be no assurance that the anticipated benefits of the 1998 acquisition
of Prisma, the 1997 acquisition of the veterinary diagnostics business of SBIO-
E, the 1996 acquisition of the business of 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

                                      -5-
<PAGE>
 
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.

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

Competition in the animal health care industry is intense.  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.  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.  Synbiotics has
incurred a consolidated accumulated deficit of $9,754,000 at December 31, 1997,
even after the release in 1996 of a $7,158,000 valuation allowance related to
deferred tax assets.  There can be no assurance that Synbiotics can generate
sufficient revenue to sustain profitability.

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/(TM)/,
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,
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.

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, a majority of the Company's vaccine products (exclusive of
its feline leukemia vaccine products) are manufactured using bulk antigen fluids
that have been supplied by a third party.  The supply agreement has expired and
the Company is currently seeking a replacement supplier for these fluids.  The
Company believes it has adequate levels of these bulk fluids to meet its
manufacturing requirements through the third quarter of 1998.  In the event that
the Company is unable to locate a replacement supplier, sales of the Company's
private label vaccine products, beginning in the fourth quarter of 1998, will be
materially adversely affected.

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, 1997,
sales to two distributors totalled 40% of the Company's net sales.  In addition,
SBIO-E's small animal products are presently sold through distributors, while
its large animal products are sold directly to laboratories.  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.

                                      -6-
<PAGE>
 
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.  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 is highly dependent, 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 requires
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.

If adequate funds are not available, Synbiotics may be required, among other
things, to delay, scale back or eliminate one or more of its research and
development programs or seek to obtain funds through arrangements with

                                      -7-
<PAGE>
 
collaborative partners or others even if the arrangements would require
Synbiotics to relinquish certain rights to certain of its technologies, product
candidates or products that Synbiotics would not otherwise relinquish.

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

Synbiotics has experienced some seasonality in its business, with sales highest
in December to April, the time period in which distributors purchase canine
heartworm diagnostic products to sell to veterinarians for the heartworm season.
This seasonality may be somewhat reduced by the acquisition of SBIO-E, which is
relatively less seasonal.  There can be no assurance that such seasonality will
not have a material adverse impact on Synbiotics' operations.

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.  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 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.  A patentholder has filed a
lawsuit asserting that the Company's key canine heartworm diagnostic tests
infringe its patent (see Item 3 - Legal Proceedings).

There can be no assurance that such patentholder or 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 result in the award of substantial
damages.  Defense of any lawsuit or failure to obtain any such license could
have a material adverse effect on Synbiotics.  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 (see Item 1 - Business--Government Regulation).  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 will be subject to foreign
regulatory requirements in such foreign jurisdictions, which vary widely from
country to country.  There can be no assurance that Synbiotics will meet and
sustain compliance with any such requirements.

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.  Product liability insurance is expensive, difficult to obtain and
may not be available in the future on acceptable terms or at all.  A successful
claim brought against Synbiotics in excess of Synbiotics' insurance coverage
could have a material adverse effect upon Synbiotics.

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

Synbiotics' research and development involves 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

Year Ended December 31, 1997 Compared to Year Ended December 31, 1996
- ---------------------------------------------------------------------

Net sales for the year ended December 31, 1997 increased by $6,069,000 or 35%
over the year ended December 31, 1996.  The increase in net sales is primarily
due to $3,724,000 in sales of diagnostic products acquired in conjunction with
the acquisition of SBIO-E in July 1997 and $1,117,000 in sales of the canine
breeding diagnostic products acquired from ICG in October 1996.  In addition,
the sales of non-SBIO-E and non-ICG diagnostic products increased 13% during
1997.  Sales of vaccine products in 1997 were flat compared to 1996.  However,
sales of vaccines to private label partners in 1997 increased by 60% over 1996,
offset by a 14% decrease in other vaccine sales due to decreased sales of bulk
feline leukemia vaccine (related to the timing of shipments as requested by OEM
customers).  Sales of vaccines have also been negatively impacted by severe
competition from Pfizer, Fort Dodge and Solvay who manufacture their own vaccine
products, whereas the Company's vaccines are all manufactured by third parties.
During the fourth quarter of 1997, the Company stopped selling its vaccines
(except for its feline leukemia vaccines) to distributors and focused its
efforts on selling vaccines to private label partners for resale to the over-
the-counter market and through catalogs.

A majority of the Company's vaccine products (exclusive of its feline leukemia
vaccine products) are manufactured using bulk antigen fluids that have been
supplied by a third party.  The supply agreement has expired and the Company is
currently seeking a replacement supplier for these fluids.  The Company believes
it has adequate levels

                                      -9-
<PAGE>
 
of these bulk fluids to meet its manufacturing requirements through the third
quarter of 1998.  In the event that the Company is unable to locate a
replacement supplier, sales of the Company's private label vaccine products,
beginning in the fourth quarter of 1998, will be materially adversely affected.

The cost of sales as a percentage of net sales decreased to 55% during 1997
compared to 56% for 1996 (i.e., gross margin increased to 45% from 44%).  The
higher gross margin is a direct result of the fact that 81% of SBIO-E's sales
relate to products manufactured by SBIO-E rather than by third party
manufacturers.  In comparison, the Company's sales, exclusive of the SBIO-E
sales, in 1997 had a 43% gross margin.  The reduced margin on 1997 non-SBIO-E
sales is due to the fact that a larger percentage of net sales during 1997 were
generated from products which are manufactured for the Company by third parties.
The Company's manufacturing costs are predominantly fixed costs.  Among the
Company's major products, DiroCHEK/(R)/ canine heartworm diagnostic products are
manufactured at Company facilities, whereas ICT GOLD/(TM)/ HW, VetRED/(R)/,
WITNESS/(R)/ and all vaccines are manufactured by third parties.  In addition to
affecting gross margins, this shift in product mix renders the Company
relatively more dependent on the third-party manufacturers.  Vaccines (other
than feline leukemia virus vaccine) have particularly been a drain on
profitability.  Gross margin during 1997 was also affected by a decrease in the
average selling prices for the Company's canine heartworm products during the
first six months of 1997 due to severe price competition from IDEXX
Laboratories, the Company's main diagnostic competitor, as well as a decrease in
average selling prices for certain potentially short-dated vaccines during the
first quarter of 1997.

Research and development expenses during 1997 increased by $698,000 or 70% over
1996.  The increase is primarily due to the acquisition of SBIO-E, which has its
own research and development group, as well as increased contracted research and
development expenses and legal expenses related to patent filings.  Research and
development expenses as a percentage of net sales were 7% and 6% during 1997 and
1996, respectively.

Selling and marketing expenses during 1997 increased by $327,000 or 8% over
1996.  The increase is due primarily to the acquisition of SBIO-E, which has its
own sales and marketing group.  Selling and marketing expenses as a percentage
of net sales were 19% and 24% during 1997 and 1996, respectively.

General and administrative expenses during 1997 increased by $1,484,000 or 72%
over 1996.  The increase is due primarily to amortization of goodwill and
additional payroll costs related to the acquisition of both SBIO-E and the
operations of ICG.  General and administrative expenses as a percentage of net
sales were 15% and 12% during 1997 and 1996, respectively.

Other income (expense) during 1997 decreased by $1,759,000 or 99% from 1996 due
primarily to the non-recurrence of the $1,159,000 gain in 1996 from the sale of
the Company's investment in Texas Biotechnology Corporation ("TBC").  The
remaining decrease is due to interest expense related to the debt incurred in
conjunction with the acquisition of SBIO-E and the non-recurrence of license
fees received in conjunction with an exclusive distribution agreement with
Daiichi Pharmaceutical Co., Ltd. for the distribution of the Company's vaccine
and diagnostic products in Japan.  The interest expense was partially offset by
an increase in interest revenue due to an increased level of invested cash
resulting from the proceeds received from the sale of the TBC shares in 1996.

The income tax provision for 1997 includes $97,000 in foreign income taxes
resulting from the SBIO-E operations.  The combined Federal and state effective
tax rate was 73% during 1997 as compared to -325% during 1996.  The income tax
provision during 1997, in addition to the foreign income taxes, comprises a
current income tax provision of $6,000 and a deferred income tax provision of
$456,000.  The income tax provision during 1996 comprises a current income tax
provision of $64,000 and a deferred income tax benefit of $7,158,000.  The
current provision for income taxes during 1997 and 1996 arose from alternative
minimum taxes due to the utilization of net operating loss carryforwards.  The
increase in the deferred provision for income taxes is due to the fact that as
of December 31, 1995 the Company provided a deferred tax asset valuation
allowance for deferred tax assets which management determined were "more likely
than not" to be unrealizable based on recent trends in operating results.  At
the end of 1996, the Company released the valuation allowance related to its
deferred tax assets based on management's

                                      -10-
<PAGE>
 
assessment that it was "more likely than not" that the Company would realize
those assets in future periods due to improvements in the Company's operating
results. As a result, $463,000 (representing the tax effect of the change in the
carrying amount of the deferred tax assets) was included in the 1997 statement
of operations because, unlike in 1996, there was no longer any valuation
allowance left to release it from. In addition, the 1997 deferred state tax
provision includes $294,000 related to the expiration of state net operating
loss carryforward. The deferred tax provision reduces the Company's deferred tax
assets, but the amount of the deferred tax provision does not actually have to
be paid to the Government.

The Company believes that earnings before interest, taxes, depreciation and
amortization ("EBITDA") is an important and meaningful tool in comparing its
performance from year to year.  While there are many interpretations in the
financial community as to the physical calculation of EBITDA, the Company
calculates EBITDA as net income plus the sum of 1) interest expense, 2) income
tax expense, 3) depreciation expense and 4) amortization expense.  However, it
should be noted that EBITDA is not an equivalent of, nor a substitute for, cash
flow.  EBITDA for 1997 was $2,712,000 as compared to $3,027,000 for 1996, a
decrease of $315,000 or 10%.  The decrease is due, in addition to the above
factors, to the non-recurrence of the 1996 gain on the sale of the TBC shares,
offset by the interest on the debt issued in conjunction with the acquisition of
SBIO-E and a larger amount of goodwill amortization in 1997 (due to a full
year's amortization related to the ICG acquisition, as well as the amortization
related to the SBIO-E acquisition).  After excluding the non-recurring 1996 gain
on the sale of the TBC shares, EBITDA increased $844,000 during 1997.

Because SBIO-E is such a large part of the post-acquisition Company, and because
of the significant amount of long-term debt the Company incurred in connection
with the acquisition, historical results of operations will not necessarily be
comparable to results of operations in the near-term future.

Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
- ---------------------------------------------------------------------

Net sales for the year ended December 31, 1996 increased by $3,541,000 or 26%
over the year ended December 31, 1995.  The increase in net sales was due to an
increase in diagnostic sales of $1,772,000 or 20%, a $1,648,000 or 33% increase
in the sales of vaccines and $121,000 of PennHIP/(R)/ and semen storage related
revenues.  The increased diagnostic sales are primarily due to increased average
selling prices, the introduction of the Company's DiroCHEK TF/(R)/ canine
heartworm diagnostic product, Assure/(R)//Parvo, a canine parvovirus diagnostic
product, and ICT GOLD/(TM)/ FeLV, the Company's new feline leukemia diagnostic,
and canine breeding diagnostic products acquired from International Canine
Genetics, Inc. ("ICG"). The increased average selling prices of the Company's
existing diagnostic products resulted from a general price increase during the
third quarter of 1996, as well as the non-recurrence of promotional pricing
which was in effect during the third quarter of 1995. Also, in 1996 the Company
was able to market its ICT GOLD/(TM)/ HW canine heartworm diagnostic for the
full year (the product was introduced in March 1995). The PennHIP/(R)/ and semen
storage revenues were due to the acquisition of ICG's operations in October
1996. Vaccine sales increased due to sales to private label partners and
increased shipments of bulk feline leukemia vaccine, offset by a decrease in
average selling prices related to certain potentially short-dated vaccines.

The cost of sales as a percentage of net sales decreased to 56% during the year
ended December 31, 1996 as compared to 59% for the year ended December 31, 1995.
The improvement is due primarily to the increase in average selling prices
discussed above and the non-recurrence of a $243,000 write-off of vaccine
inventory during 1995.  These factors were partially offset by extra costs in
connection with the 1996 transition of vaccine manufacturing from one third
party to another and by an increase in inventory reserves related to potentially
short-dated products.  In addition, the cost of products as a percentage of
product revenue is impacted by domestic shipments of bulk feline leukemia
vaccine to Rhone Merieux, Inc. (located in Athens, Georgia).  The Company has
contracted to sell bulk vaccine to Rhone Merieux, Inc. at cost because the
Company receives a royalty on Rhone Merieux, Inc.'s resulting product sales in
the United States.  By contrast, the Company's international sales of bulk
feline leukemia vaccine to Rhone-Merieux of France are at a profit, not at cost.
Cost of sales as a percentage of product revenue would have been 52% and 53%
during the years ended December 31, 1996 and 1995, respectively, if the zero
margin bulk sales were not taken into consideration.

                                      -11-
<PAGE>
 
Research and development expenses increased by $88,000 or 10% over 1995 due to
increased license amortization and consulting expenses resulting from a
licensing and research development agreement which was entered into in January
1996.  Research and development expenses as a percentage of net sales were 6%
and 7% in 1996 and 1995, respectively.

General and administrative expenses increased by $571,000 or 38% over 1995.  The
increases are due to a $335,000 compensation package related to the retirement
of the Company's President on July 31, 1996, the hiring of a new Chief Executive
Officer in May 1996 and an increase in certain patent-related legal expenses and
the amortization of intangibles purchased from ICG.  General and administrative
expenses as a percentage of net sales were 12% and 11% in 1996 and 1995,
respectively.

Other income (expense) increased during 1996 increased by $400,000 or 29% over
1995 due primarily to the sale of the Company's investment in Texas
Biotechnology Corporation ("TBC").  On February 27, 1996 and February 28, 1996,
the Company sold a total of 614,000 shares of TBC common stock on the American
Stock Exchange at an average selling price of $3.573 per share.  During the
period April 25, 1996 to May 2, 1996, the Company sold its remaining 614,000
shares of TBC common stock on the American Stock Exchange at an average selling
price of $4.205 per share.  As a result of the transactions, the Company
recognized a gain of $1,159,000 during 1996. The net proceeds received from the
sales, which totalled $4,727,000, will be used primarily for working capital
requirements and to fund business opportunities such as acquisitions.  On June
30, 1995, the Company received 573,000 shares of TBC common stock resulting from
the satisfaction of a certain contingency on May 31, 1995 related to the
acquisition of ImmunoPharmaceutics, Inc. ("IPI") by TBC in July 1994 and
recognized a gain for financial reporting purposes in the amount of $931,000.
In addition, interest income, license fees and other revenues increased $208,000
over 1995 due primarily to an increased level of invested cash resulting from
the TBC sale and a $75,000 license fee received in conjunction with the Daiichi
distribution agreement, offset by a $66,000 decrease in royalty income from
Rhone Merieux.

The Company recognized a benefit from income taxes during 1996 in the amount of
$7,094,000.  The benefit is due to the release of the Company's deferred tax
asset valuation allowance.  At December 31, 1995, the Company provided a
deferred tax asset valuation allowance for deferred tax assets which management
determined were "more likely than not" to be unrealizable based on recent trends
in operating results.  During 1996, the Company released the valuation allowance
related to its deferred tax assets based on management's assessment that it was
"more likely than not" that the Company would realize a portion of those assets
in future periods due to improvements in the Company's operating results.

The Company believes that earnings before interest, taxes, depreciation and
amortization ("EBITDA") is an important and meaningful tool in comparing its
performance from year to year.  While there are many interpretations in the
financial community as to the physical calculation of EBITDA, the Company
calculates EBITDA as net income plus the sum of 1) interest expense, 2) income
tax expense, 3) depreciation expense and 4) amortization expense.  However, it
should be noted that EBITDA is not an equivalent of, nor a substitute for, cash
flow.  EBITDA for 1996 was $3,027,000 as compared to $1,531,000 for 1995, an
increase of $1,496,000 or 98%.  The increase is due, in addition to the above
factors, to the 1996 gain on the sale of the TBC shares (an additional $931,000
was recognized in 1995 related to the acquisition of IPI by TBC), and the
goodwill amortization in 1996 related to the ICG acquisition.

FINANCIAL CONDITION

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

Management believes that the Company's present capital resources, which included
working capital of $11,258,000 at December 31, 1997, are sufficient to meet its
current working capital needs and service the debt related to the acquisition of
SBIO-E through 1998.  However, pursuant to a debt agreement with Banque Paribas,
the Company

                                      -12-
<PAGE>
 
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.

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
December to April time period, as distributors prepare for the heartworm season
by purchasing diagnostic products for resale to veterinarians.  This seasonality
may be somewhat reduced by the acquisition of SBIO-E, which is relatively less
seasonal.

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 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 and manufacturing systems used in
its U.S. operations are not year 2000 compliant.  However, the software
manufacturer has provided the necessary software to make the systems year 2000
compliant, and the Company plans on implementing the software changes in the
third quarter of 1998.  As the Company has an ongoing maintenance agreement with
the software vendor, which includes the year 2000 software changes, the Company
does not expect to have a material impact on its results of operations related
to implementing the software changes.

The computer systems of SBIO-E are not affected by the year 2000 issue as new
systems had to be acquired subsequent to the acquisition and those systems were
already year 2000 compliant.

Other
- -----

On March 6, 1998, the Company acquired by merger Prisma Acquisition Corp.
("Prisma"), a privately-held company located in Rome, NY, which develops,
manufactures and markets instruments and reagents used by veterinarians to
measure blood chemistry information at the point-of-care.  The consideration
paid to the stockholders of Prisma was a $1,000,000 convertible note, 458,000
newly issued and unregistered shares of the Company's common stock and the
issuance of options to purchase 157,000 shares of the Company's common stock,
with an exercise price of $.0016 per share, in replacement of Prisma's
outstanding stock options.  The 458,000 shares and 157,000 stock options numbers
were calculated by dividing $2,000,000 by $3.25, which was the average closing
price of Synbiotics' common stock for the thirty trading days prior to March 6,
1998.

The convertible note (which was issued to only one of the Prisma stockholders)
is due March 5, 1999, bears interest at the rate of 5% per year and is
unsecured.  The note is convertible at any time, at the option of the Company,
into a number of unregistered shares of the Company's common stock equal to the
outstanding principal and accrued interest divided by the average closing price
of the Company's common stock for the thirty trading days immediately prior to
the conversion.  The note is subordinate to the Company's notes payable to
Banque Paribas.

The Company believes that Prisma's products will be of significant strategic
importance to the Company. However, there can be no assurance that the
anticipated benefits of the acquisition will be realized. The acquisition will
involve numerous risks, including difficulties in the assimilation of the
operations, technologies and products of the Prisma, dilutive issuances of
equity and/or debt securities, accounting charges, operating companies in
different geographic locations, the potential loss of key employees of Prisma,
the diversion of management's attention from other business concerns and the
risks of entering markets in which Synbiotics has no direct prior experience. In
addition, there can be no assurance that the acquisition will not have a
material adverse effect upon Synbiotics' business, results of operations or
financial condition, particularly in the quarters immediately following the

                                      -13-
<PAGE>
 
consummation of the acquisition due to further product development work,
operational disruptions, unexpected expenses and accounting charges which may be
associated with the acquisition and integration of Prisma.

                       REPORT OF INDEPENDENT ACCOUNTANTS
                       ---------------------------------

To the Board of Directors and Shareholders
 of Synbiotics Corporation


In our opinion, based upon our audits and the report of other auditors, the
financial statements listed in the accompanying index present fairly, in all
material respects, the financial position of Synbiotics Corporation and its
subsidiary at December 31, 1997 and 1996, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1997, in conformity with generally accepted accounting principles.  These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits.  We did not audit the financial statements of Synbiotics Europe SAS,
a wholly-owned subsidiary, which statements reflect total assets of $12,991,000
at December 31, 1997 and total sales of $3,724,000 for the six months ended
December 31, 1997.  Those statements were audited by other auditors whose report
thereon has been furnished to us, and our opinion expressed herein, insofar as
it relates to the amounts included for Synbiotics Europe SAS, is based solely on
the report of the other auditors.  We conducted our audits of these statements
in accordance with generally accepted auditing standards which require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement.  An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation.  We believe that our audits and the report of other
auditors provide a reasonable basis for the opinion expressed above.

To the Board of Directors and Shareholders
 Synbiotics Europe SAS

We have audited the accompanying balance sheet of Synbiotics Europe SAS as of
December 31, 1997, and the related statements of operations, of cash flows and
of shareholders' equity, for the six month period then ended.  These financial
statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements based on
our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free from material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Synbiotics Europe SAS as of
December 31, 1997 and the results of its operations and its cash flows for the
six month period then ended in conformity with generally accepted accounting

Notes to Consolidated Financial Statements
- --------------------------------------------------------------------------------

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES:

THE COMPANY

Synbiotics Corporation (the "Company"), incorporated in 1982, is an animal
health business which develops, manufactures and markets diagnostic products and
biological products for animals. The Company's principal markets are
veterinarians and veterinary clinical laboratories in the United States and
Europe.  The Company's products are sold primarily to wholesale distributors and
direct to veterinary clinical laboratories.  In addition, due to the October
1996 acquisition of substantially all of the assets of International Canine
Genetics, Inc. (Note 2), the Company also develops and manufactures specialty
products which are marketed to veterinarians and purebred dog enthusiasts.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements of the Company include the accounts of its
wholly-owned subsidiary Synbiotics Europe SAS (Note 2).  All significant
intercompany transactions and accounts have been eliminated in consolidation.

INVENTORIES

Inventories are stated at the lower of cost or market; cost is determined using
the first-in, first-out method.

PROPERTY AND EQUIPMENT

Property and equipment, including leasehold improvements, are recorded at cost.
Maintenance costs are charged to operations as incurred.  Depreciation and
amortization are computed using the straight-line method over the estimated
useful lives of five to eight years or the lease terms, if shorter.

CERTAIN INVESTMENTS IN DEBT AND EQUITY SECURITIES

The Company determines the appropriate classification of its U.S. Government,
debt and equity securities at the time of acquisition and reevaluates such
designation as of each balance sheet date.  The Company has recorded these
investments at fair market value as it has designated them as "available for
sale".

PATENTS AND LICENSES

Patents and licenses are recorded at cost and are amortized ratably over the
life of the respective patents or licenses.

LONG-LIVED ASSETS

The Company investigates potential impairments of long-lived assets, certain
identifiable intangibles and associated goodwill, on an exception basis, when
there is evidence that events or changes in circumstances have made recovery of
an asset's carrying value unlikely.  An impairment loss is recognized when the
sum of the expected future net cash flows is less than the carrying amount of
the asset.  No such impairments of long-lived assets existed through December
31, 1997.

Notes to Consolidated Financial Statements
- --------------------------------------------------------------------------------

FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amounts for cash and cash equivalents at December 31, 1997 and 1996
approximate their fair values.  The carrying amount of long-term debt
approximates fair value at December 31, 1997 as the variable interest rate on
the debt approximates current market rates of interest.

TRANSLATION OF FINANCIAL STATEMENTS

The financial statements for subsidiaries whose functional currency is not the
U.S. dollar are translated in the following manner:  assets and liabilities at
the year end rates; shareholders' equity at historical rates; and results of
operations at the monthly average exchange rates.  The effects of exchange rate
changes are reflected as a separate component of shareholders' equity.

REVENUE RECOGNITION

Revenue from products is recognized when the products are shipped.

ADVERTISING COSTS

The Company recognizes the production costs of advertising at the time such
charges are incurred.  Advertising expense totalled $450,000, $505,000 and
$629,000 during the years ended December 31, 1997, 1996 and 1995, respectively.

STOCK-BASED COMPENSATION

The Company measures its stock-based employee compensation using the intrinsic
value method and provides pro forma disclosures of net income and earnings per
share as if the fair value method had been applied in measuring compensation
expense.

INCOME TAXES

The Company's current income tax expense is the amount of income taxes expected
to be payable for the current year.  A deferred income tax asset or liability is
computed for the expected future impact of differences between the financial
reporting and tax bases of assets and liabilities as well as the expected future
tax benefit to be derived from tax loss and tax credit carryforwards.  Valuation
allowances are established, when necessary, to reduce deferred tax assets to the
amount "more likely than not" to be realized in future tax returns.  Tax rate
changes are reflected in income during the period such changes are enacted.

NET INCOME PER SHARE

The Company adopted Statement of Financial Accounting Standards No. 128 ("SFAS
128"), "Earnings Per Share", for 1997 and retroactively restated all prior
periods to conform with SFAS 128 as required.  Basic net income per share is
computed as net income less accretion of mandatorily redeemable common stock
divided by the weighted average number of common shares outstanding during the
period.  Diluted net income per share is computed as net income less accretion
of mandatorily redeemable common stock divided by the weighted average number of
common shares and potential common shares, using the treasury stock method,
outstanding during the period (Note 10).

STATEMENT OF CASH FLOWS

For purposes of this statement, cash includes cash investments which are highly
liquid and have an original maturity of three months or less.

USE OF ESTIMATES AND KNOWN UNCERTAINTY

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.

A majority of the Company's vaccine products (exclusive of its feline leukemia
vaccine products) are manufactured using bulk antigen fluids that have been
supplied by a third party.  The supply agreement has expired and the Company is
currently seeking a replacement supplier for these fluids.  The Company believes
it has adequate levels of these bulk fluids to meet its manufacturing
requirements through the third quarter of 1998.  In the event that the Company
is unable to locate a replacement supplier, sales of the Company's private label
vaccine products, beginning in the fourth quarter of 1998, will be materially
adversely affected.

RECLASSIFICATIONS

Certain reclassifications have been made to the financial statements as of and
for the years ended December 31, 1996 and 1995 to conform with the presentation
used as of and for the year ended December 31, 1997.

NEW ACCOUNTING PRONOUNCEMENTS

In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No.  130 ("SFAS 130"), "Reporting
Comprehensive Income", which the Company is required to adopt for 1998.This
statement will require the Company to report in the financial statements, in
addition to net income, comprehensive income and its components including
foreign currency items and unrealized gains and losses on certain investments in
debt and equity securities.  Upon adoption of SFAS 130, the Company is also
required to reclassify financial statements for earlier periods provided for
comparative purposes.  The adoption of SFAS 130 will not have a significant
impact on the Company's consolidated financial statement disclosures.

In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No.  131 ("SFAS 131"), "Disclosures About
Segments of an Enterprise and Related Information", which the Company is
required to adopt for its 1998 annual financial statements.  This statement
establishes standards for reporting information about operating segments in
annual financial statements and requires selected information about operating
segments in interim financial reports issued to stockholders.  It also
establishes standards for related disclosures about products and services,
geographic areas and major customers.  Under SFAS 131, operating segments are to
be determined consistent with the way that management organizes and evaluates
financial information internally for making operating decisions and assessing
performance.  The Company has not determined the impact of the adoption of this
new accounting standard on its consolidated financial statement disclosures.

NOTE 2 - ACQUISITIONS:

On July 9, 1997, the Company acquired Synbiotics Europe SAS ("SBIO-E") (formerly
Rhone Merieux Diagnostics, S.A.S.), the worldwide veterinary diagnostic business
of Rhone Merieux S.A.S. pursuant to purchase agreements dated May 14, 1997 and
amended July 9, 1997.  The consideration paid to Rhone Merieux was $10,659,000
in cash and 759,000 shares of newly issued, unregistered Synbiotics common stock
valued at $3,178,000 (based upon the closing price of Synbiotics' common stock
on July 9, 1997 which was $4.1875 per share) (Note 7).  The shares issued by the
Company include 230,000 shares which have been placed in escrow pending certain
U.S. regulatory approvals and subsequent sales of related products. The cash
portion of the consideration was provided by a series of loans obtained from
Banque Paribas (Note 6).  Depending on performance of the combined business in
the three years following the acquisition, Synbiotics may also pay up to
$3,600,000 in contingent cash payments.  The transaction was accounted for as a
purchase.  Goodwill arising from the transaction totalled $6,612,000 which is
being amortized over an estimated useful life of 15 years utilizing the
straight-line method.  The $3,178,000 common stock portion of the of the
purchase price is considered a non-cash financing activity for purposes of the
statement of cash flows.  The acquisition was effective as of July 1, 1997.

Rhone Merieux and Synbiotics also entered into related agreements covering the
supply of various products and services, collaborative research and development,
licenses of Rhone Merieux patents, and the distribution of certain of the
acquired products by Rhone Merieux.  The collaborative research agreement gives
Synbiotics a right of first refusal to acquire technology or products emanating
from Rhone Merieux's future research efforts that have potential veterinary
diagnostic applications.

On October 25, 1996, the Company acquired substantially all of the assets of
International Canine Genetics, Inc. ("ICG") pursuant to a purchase agreement
dated July 23, 1996 and amended September 7, 1996.  The operations acquired from
ICG consist of the manufacturing and marketing of canine reproduction diagnostic
products and services, PennHIP(R) (a diagnostic test for canine hip dysplasia),
nutritional supplements and a line of coat and skin care products to breeders
and owners of purebred dogs and their veterinarians.

The consideration paid to ICG was $1.00 plus 1,152,000 shares of Synbiotics
common stock valued at $4,852,000 (based upon the average closing price of
Synbiotics' common stock, for the period October 18, 1996 through October 24,
1996, which was $4.2125 per share).  The Company also assumed approximately
$262,000 of outstanding ICG liabilities which were due and payable as of the
closing date.  In addition, all of ICG's outstanding warrants and stock options
were made exercisable for an adjusted number of shares of Synbiotics common
stock.  Prior to the acquisition, S.R. One, Limited, ICG's largest shareholder,
purchased 237,000 shares of newly issued Synbiotics common stock for $1,000,000
(based upon the average closing price of Synbiotics' common stock, for the
period October 18, 1996 through October 24, 1996, which was $4.2125 per share).
The transaction was accounted for as a purchase.  Goodwill arising from the
transaction totalled $5,407,000 which is being amortized over an estimated
useful life of 15 years utilizing the straight-line method.  The assets acquired
and liabilities assumed are considered non-cash investing activities for the
purposes of the statement of cash flows.

The Company's statement of operations includes the results of operations of
SBIO-E for the period July 1, 1997 to December 31, 1997 and the results of
operations of ICG for the period October 25, 1996 to December 31, 1996 and for
the year ended December 31, 1997.  The following are unaudited pro forma results
of operations as if the SBIO-E transaction had been consummated on January 1,
1996 and the ICG transaction had been consummated on January 1, 1995:

NOTE 3 - DISPOSITION OF INVESTMENT AND RELATED PARTY TRANSACTION:

On July 25, 1994, ImmunoPharmaceutics, Inc. ("IPI"), of which the Company was a
41% shareholder, was acquired by Texas Biotechnology Corporation ("TBC") in a
triangular merger transaction whereby unregistered shares of TBC common stock
were issued in exchange for all of the outstanding stock of IPI.  The Company's
655,000 TBC shares were registered effective December 6, 1995.

On June 30, 1995, the Company received an additional 573,000 shares of TBC
common stock resulting from the satisfaction of a certain contingency on May 31,
1995 related to the acquisition of IPI by TBC.  Accordingly, the Company
recognized a gain for financial reporting purposes in the amount of $931,000,
based on the closing price of TBC common stock on May 31, 1995 of $1.625 per
share as reported on the American Stock Exchange.

On February 27, 1996 and February 28, 1996, the Company sold a total of 614,000
shares of TBC common stock on the American Stock Exchange at an average selling
price of $3.573 per share.  During the period April 25, 1996 to May 2, 1996, the
Company sold its remaining 614,000 shares of TBC common stock on the American
Stock Exchange at an average selling price of $4.205 per share.  As a result of
the transactions, the Company received net proceeds totalling $4,727,000 and
recognized a gain of $1,159,000.

The Company charged its former affiliate, IPI, now a wholly-owned subsidiary of
TBC, for shared costs including, but not limited to, rent, utilities and
property taxes through December 31, 1996.  Such charges totalled $343,000 and
$357,000 during the years ended December 31, 1996 and 1995, respectively.

NOTE 6 - LONG-TERM DEBT:

In conjunction with the acquisition of SBIO-E (Note 2), the Company obtained a
series of loans from Banque Paribas (the "Bank") as follows: 1) $5,000,000, due
May 31, 2002, bearing interest at the rate of LIBOR plus 2.50% (effectively
8.25% at December 31, 1997), payable quarterly beginning August 31, 1997 in the
amount of $250,000 of principal plus accrued interest, and secured by
substantially all of the Company's assets; and 2) $5,000,000, due May 31, 2003,
bearing interest at the rate of LIBOR plus 3.00% (effectively 8.75% at December
31, 1997), interest only payable quarterly beginning August 31, 1997, and
secured by substantially all of the Company's assets.  In accordance with the
debt agreements, the Company has entered into an interest rate collar agreement
with a financial institution, which expires in May 2003, whereby the LIBOR rate
payable by the Company, on a notional principal amount equal to the then
outstanding principal balance, cannot fall below 5.70% nor rise above 7.08%. The
Company did not pay or receive any premiums associated with this agreement,
which is maintained for interest rate protection and not for speculative
purposes. Accordingly, no amounts have been recorded in the accompanying
financial statements with respect to this agreement. At December 31, 1997, the
fair value of the interest collar, as confirmed by the counterparty to the
instrument, was not material.

The Company incurred deferred debt issuance costs totalling $949,000 and a debt
discount totalling $1,003,000, representing the value of common stock warrants
issued to the Bank (Note 8).  The debt discount and deferred debt issuance
costs, which have been allocated evenly to the two notes payable, are being
amortized over the lives of the loans using the effective interest method.

In addition, the Company also obtained a revolving line of credit from the Bank
whereby the Company may borrow up to $5,000,000 as determined by a borrowing
base calculation.  The line of credit bears interest at the rate of prime plus
 .75% (effectively 9.25% at December 31, 1997), with interest only payments to be
made quarterly beginning August 31, 1997.  Any outstanding principal is due May
31, 2002, although a portion of the outstanding principal may become due and
payable as determined by a monthly borrowing base calculation.  There were no
borrowings outstanding under the line of credit at December 31, 1997.  The
Company is required to pay a quarterly commitment fee equal to 0.5% per annum on
the average unused portion of the line of credit facility.

The Bank 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.

Principal payments scheduled during the next five years and thereafter are as
follows: 1998 - $1,000,000, 1999 -$1,000,000, 2000 - $1,000,000, 2001 -
$1,000,000, 2002 - $500,000 and 2003 - $5,000,000.  Interest paid during 1997
totalled $262,000.

NOTE 7 - MANDATORILY REDEEMABLE COMMON STOCK:

The 759,000 shares issued in conjunction with the acquisition of SBIO-E (Note 2)
are subject to certain registration rights as well as put and call provisions.
The put option gives Rhone Merieux the right, beginning on July 9, 2001, to sell
all or any portion of its shares to the Company at a price of $5 per share.  The
call option gives the Company the right to acquire, at any time, all or any
portion of the shares then owned by Rhone Merieux at a per share price of the
greater of the average closing sale price of the Company's common stock for the
30 day period prior to the call or $5.  Should the Company exercise its call
option prior to July 9, 2001 at a call option price greater than $5 per share,
the agreement requires the difference between the per share call option price
and $5 to be shared by the Company and Rhone Merieux on a sliding scale basis.
In addition, should Rhone Merieux sell all or any portion of the shares to a
third party prior to July 9, 2001 at a price greater than $5 per share, the
agreement requires the difference between the per share sales price and $5 to be
shared by the Company and Rhone Merieux on a sliding scale basis.  The Company
has classified the shares on the balance sheet as mandatorily redeemable and is
accreting the value of the shares to the put option price, using the interest
method, with the accretion being charged directly to retained earnings.


NOTE 8 - SHAREHOLDERS' EQUITY:

In May 1996, in conjunction with an employment agreement, the Company granted an
award of 10,000 shares of unregistered Synbiotics common stock and recognized
compensation expense in the amount of $39,000.

STOCK WARRANTS

In conjunction with the acquisition of SBIO-E (Note 2), the Company issued to
Banque Paribas a warrant to purchase 240,000 unregistered shares of the
Company's common stock at an exercise price of $.01 per share.  The warrant is
exercisable at any time through May 31, 2007 and contains certain anti-dilution
provisions and registration rights.  The Company has valued the warrant at
$1,003,000 using the Black-Scholes option pricing model.

In conjunction with the acquisition of ICG (Note 3), the Company assumed all of
the outstanding ICG stock warrants, after giving effect to the exchange ratio
inherent in the transaction.  As a result, 284,000 shares of the Company's
common stock were reserved for issuance with an exercise price of $4.54 per
share.

STOCK OPTION PLANS

The Company recognizes compensation expense related to its stock option plans
using the intrinsic value method.  Had compensation expense for the Company's
stock option plans been determined based on the fair value at the grant dates,
the Company's net income and net income per share would have been reduced to the
pro forma amounts indicated below:

The Company had adopted a series of non-qualified and incentive stock option
plans (the "Predecessor Plans").  In April 1995, the Company adopted the 1995
Stock Option/Stock Issuance Plan (the "1995 Plan") whereby an aggregate of
1,300,000 shares of the Company's common stock, inclusive of all optioned shares
that were exercisable and/or issuable under the Predecessor Plans, were reserved
for issuance.  No further option grants may be made under the Predecessor Plans.
The 1995 Plan is administered by the Board of Directors and provides that
exercise prices shall not be less than 85 percent (non-qualified options) and
100 percent (incentive options) of the fair market value of the shares at the
date of grant.  Options will generally vest at the rate of 1/16th of the granted
shares in each continuous quarter of employment and have an exercise period not
more than ten years from date of grant.

In October 1996, the Company adopted the 1996 Stock Option Plan (the "1996
Plan") whereby an aggregate of 250,000 shares of the Company's common stock were
reserved for issuance.  The 1996 Plan is administered by the Board of Directors
and provides for the issuance of non-qualified options to key employees,
consultants and other independent contractors (excluding officers and directors,
other than newly-hired directors or officers) at exercise prices to be
determined by the Board of Directors at its discretion.  Options will generally
vest at the rate of 1/16th of the granted shares in each continuous quarter of
employment and have an exercise period not more than ten years from date of
grant.

In April 1997, the 1995 Plan was amended to incorporate the 1996 Plan into the
1995 Plan and add an additional 450,000 shares to the maximum authorized for
issuance.  Under the 1995 Plan, an aggregate of 2,000,000 shares of the
Company's common stock, inclusive of all optioned shares that were exercisable
and/or issuable under the 1996 Plan, were reserved for issuance.  No further
option grants may be made under the 1996 Plan.

For disclosure purposes, the fair value of each option granted is estimated on
the date of grant using the Black-Scholes option pricing model with the
following weighted-average assumptions for grants in 1997, 1996 and 1995,
respectively:  dividend yield of 0% for all years; expected volatility of 56.8%,
57.8% and 56.5%; risk-free interest rates of 6.2%, 5.8% and 6.1%; and expected
lives of 2.7 year, 2.5 years and 2.2 years.

In conjunction with the acquisition of ICG (Note 2), the Company assumed all of
the outstanding ICG stock options (the "ICG Plan"), after giving effect to the
exchange ratio inherent in the transaction.  As a result, 93,000 shares of the
Company's common stock were reserved for issuance with exercise prices ranging
from $4.54 to $25.42 per share.  As of December 31, 1997, there were 93,000
shares outstanding under the ICG Plan with a weighted-average exercise price of
$9.91 per share and a weighted-average remaining contractual life of 6.50 years.
Options to purchase 78,000 shares were exercisable under the ICG Plan with a

December 31, 1995, the Company provided a deferred tax asset valuation allowance
for deferred tax assets which management determined were "more likely than not"
to be unrealizable based on recent trends in operating results.  During 1996,
the Company released the valuation allowance related to its deferred tax assets
based on management's assessment that it was "more likely than not" that the
Company would realize those assets in future periods due to improvements in the
Company's operating results.  The decreases are also due to the utilization of
net operating loss carryforwards during the year ended December 31, 1996 and the
realization of the remaining equity in losses of IPI due to the sale of the
Company's investment in TBC (Note 3).  In addition, the valuation allowance for
state deferred tax assets was further reduced due to the expiration of a portion
of the state net operating loss carryforwards.

applying the statutory federal income tax rate to income before income taxes

Barnes-Jewish Hospital of St. Louis (the "Hospital") has filed a lawsuit against
the Company claiming that the Company infringes a patent owned by the Hospital
and is seeking unspecified damages.  The Hospital is the owner of a patent which
the Hospital alleges covers the Company's canine heartworm diagnostic products.
The Company is also the owner of several patents which cover its canine
heartworm diagnostic products.  The Company believes that it does not infringe
the Hospital's patent, and also believes that the Hospital's patent is invalid.
The Company is vigorously defending the lawsuit which is in the discovery stage.
No provision has been made in the financial statements related to this lawsuit
as the likelihood of an unfavorable outcome cannot be determined at this time.


NOTE 12 - SIGNIFICANT CUSTOMERS:

The Company had sales to two customers totalling 40% of gross revenues during
the year ended December 31, 1997. During the year ended December 31, 1996, sales
to two customers totalled 37% of gross revenues.  Sales totalling 44% of gross
revenues during the year ended December 31, 1995 were made to two customers.
Sales to foreign customers, primarily in Europe, totalled 26%, 16% and 12% of
product revenues during the years ended December 31, 1997, 1996 and 1995,
respectively.  The Company grants credit to all of its customers, substantially
all of whom are in the animal health products industry.


NOTE 13 - SUBSEQUENT EVENT:

On March 6, 1998, the Company acquired by merger Prisma Acquisition Corp.
("Prisma"), a privately-held company located in Rome, NY, which develops,
manufactures and markets instruments and reagents used by veterinarians to
measure blood chemistry information at the point-of-care.  The consideration
paid to the stockholders of Prisma was a $1,000,000 convertible note, 458,000
newly issued and unregistered shares of the Company's common stock and the
issuance of options to purchase 157,000 shares of the Company's common stock,
with an exercise price of $.0016 per share, in replacement of Prisma's
outstanding stock options.  The 458,000 shares and 157,000 stock options numbers
were calculated by dividing $2,000,000 by $3.25, which was the average closing
price of Synbiotics' common stock for the thirty trading days prior to March 6,
1998.

The convertible note (which was issued to only one of the Prisma stockholders)
is due March 5, 1999, bears interest at the rate of 5% per year and is
unsecured. The note is convertible at any time, at the option of the Company,
into a number of unregistered shares of the Company's common stock equal to the
outstanding principal and accrued interest divided by the average closing price
of the Company's common stock for the thirty trading days immediately prior to
the conversion. The note is subordinate to the Company's notes payable to Banque
