PART I



Item 1.    Business



General



Synbiotics Corporation is a leading
provider of rapid diagnostic and laboratory diagnostic products for the animal health care industry. We are one of a small number of companies that focuses exclusively on animal health and we are a major provider of diagnostic products to the animal
health market. Our product portfolio consists of 96 diagnostic test kits and detection devices. Many of our products hold strong positions in their specific markets. In recent years we have been moving to refocus our business on our core diagnostics
products.



In 2002, we sold our instrument manufacturing
operations, which were located in Rome, New York, and we disposed of our PennHIP® business, which was located in Malvern, Pennsylvania.



In 2001, we ended our participation in the veterinary vaccines business.



In 2000, we acquired our poultry diagnostic products business, and we disposed of W3COMMERCE, an Internet marketing services subsidiary.



Market and Product Overview



We sell our products globally to veterinary practices, laboratories and
poultry producers. We believe that our current and intended future products will offer veterinarians and other professionals an opportunity to improve the quality and expand the scope of animal health care services.



Our most commercially successful products are our canine heartworm
diagnostics (representing 24% of our net sales in 2003, and 36%, of our net sales in 2002 and 2001). We estimate that we have approximately a 15% share of the estimated $30 million U.S. canine heartworm diagnostics market. Sales of these products
have historically been strongest during the first half of the year when distributors purchase merchandise to sell to veterinarians for the heartworm season.



Marketing



We sell our products in the United States, Canada, Europe, Africa, Oceania, Asia and Latin America. In the United States, we market our line both directly
and 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. We also sell directly to
laboratories and other centralized facilities. Outside the United States, we sell our small-animal products through distributors, and our food animal products directly to laboratories. We maintain a marketing and sales force, which trains
distributor representatives, responds to technical inquiries, promotes products directly to veterinarians, laboratories and poultry producers.



Manufacturing



We manufacture most of our products at our facilities located in San Diego, California and Lyon, France. However, we rely on outside manufacturers for our
WITNESS® canine heartworm, feline leukemia and
canine parvovirus diagnostic products, and our SCA 2000 instrument products. We manufacture the key biological materials contained in our WITNESS® canine heartworm, feline leukemia and canine parvovirus diagnostic products.



Until early 2003, we relied on Agen Biomedical Limited as the contract manufacturer of our key Witness® products. After Agen terminated the supply agreement,
we identified a replacement, U.S.-based contract manufacturer and began the re-introduction of these Witness® products to the market in January 2004.

Patents and Trade Secrets



We believe that our proprietary technology is an important competitive factor in our business, and that protection of our
intellectual property rights is a high priority. The basic hybridoma (the cell that produces the monoclonal antibody) technology is in the public domain and is therefore not patentable. However, numerous improvements, variations and applications of
hybridoma technology may prove to be patentable. Considering the difficulty of enforcing any patent rights to such improvements, and the rapid advancements in the field, we generally seek, and will continue to seek, to protect our interests by
treating our particular variations in the production of monoclonal antibodies as trade secrets. We also pursue, and intend to continue to aggressively pursue, protection for new products, new methodological concepts, and compositions of matter
through the use of patents where obtainable. At present, we have been granted 8 U.S. patents. In fact, we are currently involved in patent litigation with Agen to enforce our heartworm detection patent; in 2002 we successfully settled litigation
with Heska Corporation pertaining to our heartworm detection patent.



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). Certain foreign countries in which we market our diagnostic products also require governmental approval for
animal diagnostic products. Our instrumentation products are not subject to USDA regulation. Our canine semen freezing products and canine ovulation timing diagnostic products 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.



Our manufacturing facilities in San Diego and Lyon, France are licensed by the USDA and adhere to Good Manufacturing Practices (GMP) standards. Our French manufacturing facility, which is ISO 9002
certified, is not licensed by any foreign regulatory agency as there is no licensing requirement. The manufacturing facilities of our important suppliers are subject to licensing and regulatory approval in both the United States and Europe.



In addition to the foregoing, our operations may be subject to
future legislation and/or rules issued by domestic or foreign governmental agencies with regulatory authority relating to our business.



Competition



We are a major provider of diagnostic products to the animal health market. Most of our 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 $476,000,000 (for 2003) that develops, manufactures, and distributes detection and diagnostic products for animal health, food, and environmental testing applications.



The market for animal health care products is extremely competitive.
Companies in the animal health care market compete to develop new products, to market and manufacture products efficiently, to implement effective research strategies, and to obtain regulatory approval. Our current competitors include IDEXX
Laboratories, a significantly larger company, Heska Corporation, to whom we granted a non-exclusive license of our canine heartworm patent in 2003, and Agen Biomedical Limited., the former contract manufacturer of certain of our WITNESS® diagnostic products. These companies have greater
financial, manufacturing, marketing, and research resources than we do. In addition, IDEXX Laboratories prohibits its distributors from selling competitors products, including ours. Further, additional competition could come from new entrants
to the animal health care market. We cannot assure you that we will be able to compete successfully in the future or that competition will not harm our business.



Our core canine heartworm diagnostic products can be subject to significant additional competition, affecting both our
market share and our average selling price, if we are unable to enforce the United States patent

which underlies our products. We sued Heska for infringing our patent; the suit was settled in 2003 when Heska agreed to pay us a royalty. We are also suing
Agen, which entered the U.S. market in 2003, for infringing our patent; in March 2004 we obtained temporary injunctive relief from the United States District Court, barring Agen from continuing its allegedly infringing activities. However, our
patent expires in December 2005.



Research and Development



We spent approximately $1,177,000 and $1,380,000 on research and
development activities during the years ended December 31, 2003 and 2002, 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, 2003, we had a
total of 94 employees worldwide, 92 of whom were full-time.



Raw Materials



The manufacturing of diagnostics and diagnostic
instruments requires raw materials which generally are, and have been, readily available from several sources.



Financial Information About Industry Segments and Financial Information About Foreign and Domestic Operations and Export Sales



See Note 14 to our financials statements in Item 8 of Part II of this Form 10-K.



Item 2.    Properties



We lease two buildings in San Diego, California. The buildings contain approximately 42,000 square feet of space, and house our corporate and sales headquarters, executive offices, U.S. research and development laboratories and
manufacturing facilities. We also lease an approximately 25,000 square foot building in Lyon, France which houses Synbiotics Europes (SBIO-E) corporate and sales headquarters, executive offices, research and development
laboratories and manufacturing facilities. In addition, we lease a small research office in College Park, Maryland.



We believe that these facilities are adequate for our current level of operations.



Item 3.    Legal Proceedings



Agen Biomedical Limited v. Synbiotics CorporationUnited States District Court for the Southern District of California



On September 2, 2003, Agen Biomedical Limited (Agen} filed a lawsuit against us seeking two specific forms of declaratory relief. First, Agen
has asked for a declaratory judgment that Agens canine heartworm diagnostic test kit does not infringe our U.S. Patent No. 4,789,631 pertaining to heartworm detection technology. Agen also asked for a declaratory judgment that Claim 5 of our
U.S. Patent No. 4,789,631 is invalid. We filed a motion to transfer the lawsuit to the United States District Court for the Southern District of California. On November 7, 2003, our motion was granted and the case was transferred.

Synbiotics Corporation v. Agen Biomedical LimitedUnited States District Court for the Southern District of
California



On September 3, 2003, we filed a patent
infringement lawsuit against Agen claiming that Agen has infringed our U.S. Patent No. 4,789,631 pertaining to heartworm detection technology. In addition to seeking unspecified damages, we have asked the Court for a declaratory judgment that Agen
has willfully infringed Claim 5 of our U.S. Patent No. 4,789,631. We have also asked the Court for a temporary restraining order and a preliminary injunction against Agen, preventing Agen from importing, selling or offering for sale their canine
heartworm diagnostic test kit in the United States.



On March
15, 2004, the Court issued a temporary restraining order against Agen, preventing Agens canine heartworm diagnostic product from entering the United States market. The Court ordered that Agen, their directors, officers, employees, agents,
servants, and all those in active concert or participation with them, are restrained from importing, making, using, selling, or offering for sale, in the United States, any canine heartworm kit containing the DI 16 872.5 monoclonal antibody
manufactured or supplied by Agen. The Court ruled earlier that we were likely to succeed on the merits of our claim that Agens canine heartworm diagnostic product, STATScreenTMCHW, which contains our DI 16 872.5 monoclonal antibody, infringed our United States Patent 4,789,631. A preliminary injunction hearing was held on April 15,
2004, and on April 21, 2004, the Court denied our motion and dissolved the temporary restraining order. In conjunction with the temporary restraining order, we were required to post a $250,000 bond; the Court has not yet released the bond.



The lawsuit is currently in the discovery stage, and a trial
date is scheduled for June 28, 2004.



Agen Biomedical Limited v.
Synbiotics CorporationSan Diego County Superior Court



On March 8, 2004, Agen filed an action against us in the San Diego County Superior Court seeking a declaratory judgment and specific performance requiring us to sell them certain biologicals, including the patented canine heartworm test
biologicals, even after the 2003 termination of the supply agreement between Agen and us. A preliminary injunction hearing was held on May 18, 2004; the Court granted Agens motion for a preliminary injunction, and ordered us to supply Agen
with 2,800 milligrams of biologicals.



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



The Annual Meeting of Shareholders was held on October 2, 2003. The following matters were submitted to a vote, with the results below:

Results of Operations



Year Ended December 31, 2003 Compared to Year Ended December 31, 2002



Our net sales for 2003 decreased by $2,557,000 or 12% from 2002. The decrease
reflects a decrease in our diagnostic product sales of $2,858,000 offset by an increase in our instrument product sales of $301,000. Sales of our diagnostic products decreased due to the termination by Agen of our supply agreement under which Agen
supplied us with certain of our Witness® diagnostic
products, as discussed below, leaving us with no inventory of these products for over half the year. Our instrument product sales increased primarily due to increased placements of our SCA 2000 blood coagulation timing instrument, and the resulting sales of the related
consumables.



In April 2003, we were notified by Agen that Agen
was terminating its supply agreement with us due to late payment of invoices for test kits. Agen contract manufactured certain of our Witness® in-clinic diagnostic products including canine heartworm, feline leukemia, feline heartworm and canine parvovirus, using key biological components
which we manufacture at our facilities and had provided to Agen. These Witness® products represented $4,345,000 and $8,069,000 of our net sales during 2003 and 2002, respectively. We have notified Agen that Agen did not have the right to terminate the Agreement, and that it acted wrongfully in
terminating the Agreement.



We identified a U.S.-based
alternate contract manufacturer of the same Witness® products previously manufactured for us by Agen. We licensed the alternate-source Witness® canine heartworm product with the USDA, and we began selling this product in January 2004. We also anticipate having the alternate-source Witness® feline leukemia and canine parvovirus products
available for sale late in the second quarter of 2004. In addition to the material impact during 2003, we also believe that our results of operations and financial condition could be materially adversely affected in 2004 and beyond if we are unable
to successfully reintroduce the alternate-source products into the market.



Agen has introduced into the U.S. market a canine heartworm diagnostic product which is essentially identical to our Witness® canine heartworm diagnostic test kit, including biological components which incorporate our patented technology. In September 2003, we filed a
patent infringement lawsuit against Agen claiming that Agen has willfully infringed our U.S. Patent No. 4,789,631 pertaining to heartworm detection technology. In addition to seeking damages, we are asking for an injunction against Agen, preventing
Agen from importing, selling or offering for sale their canine heartworm diagnostic test kit in the United States.



On March 15, 2004, the Court issued a temporary restraining order against Agen, preventing Agens canine heartworm diagnostic product from entering
the United States market. The Court ordered that Agen, their directors, officers, employees, agents, servants, and all those in active concert or participation with them, are restrained from importing, making, using, selling, or offering for sale,
in the United States, any canine heartworm kit containing the DI 16 872.5 monoclonal antibody manufactured or supplied by Agen. The Court ruled earlier that we were likely to succeed on the merits of our claim that Agens canine heartworm
diagnostic product, STATScreenTMCHW, which contains our DI 16 872.5 monoclonal antibody, infringed our United
States Patent 4,789,631. A preliminary injunction hearing was held on April 15, 2004, and on April 21, 2004, the Court denied our motion and dissolved the temporary restraining order. In conjunction with the temporary restraining order, we were
required to post a $250,000 bond; the Court has not yet released the bond. The lawsuit is currently in the discovery stage, and a trial date is scheduled for June 28, 2004.

Should Agen prevail at trial, our future sales of canine heartworm diagnostics products in general, our
Witness® line of products, and especially our
Witness® canine heartworm diagnostic product, may
be materially adversely affected due to market competition from Agens product. We believe that our first quarter 2004 sales and margins were penalized by competition from Agens products.



Not only has Agen increased the competition in the canine heartworm market,
they have also significantly eroded the average selling price of the product in the marketplace. We do not believe that this erosion will be easily reversed, especially after our patent expires in 2005.



We recognize revenue from product sales when title and risk of loss transfer
to our customer, which is generally upon shipment. Amounts we charge to our customers for shipping and handling are included in our net sales. We provide promotional discounts and rebates to certain of our distributors. Based upon the structure of
these rebate programs and our past history, we are able to accurately estimate the amount of rebates at the time of sale. These rebates are recorded as a reduction of our net sales. We recognize license fee revenue ratably over the license term when
we have further performance obligations to our licensee. In the event that we have no further performance obligations to our licensee, we recognize license fee revenue upon receipt.



Our cost of sales as a percentage of our net sales was 49% during 2003 and 2002. The preservation of margin despite reduced
sales was heartening, because a significant portion of our internal manufacturing costs are fixed. Among our major products, our DiroCHEK® canine heartworm diagnostic products are manufactured at our facilities, whereas our WITNESS® in-clinic canine heartworm, feline leukemia, and canine parvovirus diagnostic products
and our SCA 2000 instrument products are
manufactured by third parties. We manufacture the key biological materials contained in our WITNESS® canine heartworm, feline leukemia and canine parvovirus diagnostic products. In addition to affecting our gross margins, outsourcing of manufacturing renders us relatively more dependent
on the third-party manufacturers. Agen, the previous contract manufacturer of certain of our Witness® products, ceased to supply us with those products In April 2003. We identified a U.S.-based alternate contract manufacturer of the same Witness® products previously contract manufactured for us by Agen, and the cost of these
products to us is lower than the cost of those contract manufactured for us by Agen. In 2003 we also incurred costs to re-license these products with the USDA.



Our research and development expenses decreased by $203,000 or 15% during the year ended December 31, 2003 as compared to the year ended December 31,
2002. The decreases are a result of a cost reduction program that was implemented at the end of the third quarter of 2002, offset by costs incurred 2003 related to the re-launching of our Witness® canine heartworm product. Our research and development expenses as a percentage of our
net sales were 6% during 2003 and 2002.



Our selling and
marketing expenses decreased $228,000 or 5% during 2003 as compared to 2002. The decreases are a result of a cost reduction program, including reductions in headcount, that were implemented at the end of the third quarter of 2002. Our selling and
marketing expenses as a percentage of our net sales were 22% and 20% during 2003 and 2002, respectively.



Our general and administrative expenses decreased by $5,283,000 or 60% during 2003 as compared to 2002. The decrease during 2003 was primarily
attributable to the non-recurrence of $3,682,000 of retention bonuses that became payable in the first quarter of 2002. The decrease was also attributable to a cost reduction program, including reductions in headcount, that was implemented at the
end of the third quarter of 2002, and favorable effects of foreign currency exchange rates on our intercompany balances. Our general and administrative expenses as a percentage of our net sales were 19% and 41% during 2003 and 2002, respectively.
Excluding the first quarter 2002 bonus expense our general and administrative expenses would have been $5,090,000 or 24% of our net sales during 2002.



As previously mentioned, we are currently involved in patent litigation with Agen. As a result, we have incurred, and we will be incurring, material
litigation expenses.

In November 1998, we filed a lawsuit against Heska Corporation alleging that Heska infringed our U.S.
Patent No. 4,789,631 relating to heartworm diagnostic technology. In March 2003, we entered into settlement and license agreements with Heska which resolved all outstanding claims in the lawsuit. As part of those agreements, each party has licensed
certain intellectual property rights from the other party, including Heska licensing from us the patent relating to the heartworm diagnostic technology. In addition, we received $250,000 in April 2003, we will receive $265,000 in 24 monthly
installments of $11,000 beginning in January 2004 and we receive royalty payments on sales of licensed canine heartworm diagnostic products beginning April 2003. As a result, we recorded a one-time credit to operating expenses totaling $515,000
during 2003. We recognized royalty income related to this license totaling $277,000 during 2003.



Our net interest expense decreased by $177,000 or 26% during 2003 as compared to 2002. The decrease was due to decreases in the prime rate, and to
decreases in the outstanding principal balances of our bank debt.



We recognized a benefit from income taxes of $2,000 during 2003 as compared to a provision for income taxes of $7,000 during 2002. We are limited in the utilization of certain of our Federal and state net operating loss carryforwards. As a
result of this limitation, $15,351,000 of our Federal net operating loss carryforwards, and $969,000 of our state net operating loss carryforwards, may expire before they can be utilized. In addition, California placed a moratorium on the
utilization of net operating loss carryforwards for 2003.



In
the first quarter of 2002, we adopted Statement of Financial Accounting Standards No. 142 (FAS 142), Goodwill and Other Intangible Assets. In connection with the adoption of FAS 142, we performed a transitional goodwill
impairment assessment. As a result of this impairment assessment, we recorded an impairment of $7,649,000, net of income tax benefit of $106,000, which is classified as a cumulative effect of a change in accounting principle in the first quarter of
2002. FAS 142 requires that we perform subsequent impairment assessments on an annual basis, or on an interim basis if events occur that may cause an impairment of our goodwill and other intangible assets. In 2002, as a result of the annual
assessment based upon the market price of the our common stock on December 31, 2002, we recorded an additional impairment loss of $2,877,000. Based upon the market price of the Companys common stock on December 31, 2003, there was no
impairment loss resulting from the annual impairment assessment in 2003.



Year Ended December 31, 2002 Compared to Year Ended December 31, 2001



Our net sales for 2002 decreased by $4,143,000 or 16% from 2001. The decrease reflects a decrease in our diagnostic product sales of $4,012,000 primarily related to canine heartworm diagnostic products. Sales of our
diagnostic products decreased due to the loss of one of our larger distributors in January 2002 who accounted for $1,617,000 of our sales in 2001, an additional $599,000 related to the fourth quarter 2001 transfer of our Japanese diagnostic business
to a third party as part of a license agreement, and increased competition in the canine heartworm market. The increased competition in the canine heartworm market resulted from IDEXX Laboratories combination in-clinic diagnostic test. In
addition, our sales in France for the year fell by $635,000 or 26% due primarily to the French authorities decisions to no longer require cattle to be tested annually for tuberculosis.



Our license fee revenue for 2002 decreased by $719,000 or 71% from 2001. The
decrease is due to the recognition, in June 2001, of the remainder of deferred license fee revenue upon the termination of a vaccine supply agreement with Merial.



We recognize revenue from product sales when title and risk of loss transfer to our customer, which is generally upon
shipment. Amounts we charge to our customers for shipping and handling are included in our net sales. We provide promotional discounts and rebates to certain of our distributors. Based upon the structure of these rebate programs and our past
history, we are able to accurately estimate the amount of rebates at the time of sale. These rebates are recorded as a reduction of our net sales. We recognize license fee revenue ratably over the license term when we have further performance
obligations to our licensee. In the event that we have no further performance obligations to our licensee, we recognize license fee revenue upon receipt.

Our cost of sales as a percentage of our net sales was 49% during 2002 compared to 45% during 2001. The
lower gross margins are a direct result of the decrease in our sales during 2002, and the fact that a significant portion of our manufacturing costs are fixed.



Among our major products, our DiroCHEK® canine heartworm diagnostic products are manufactured at our facilities, whereas our WITNESS® canine heartworm and feline leukemia diagnostic products and the SCA 2000 products are manufactured by third parties. Our
poultry diagnostic products were manufactured for us by a third party during 2001. In addition to affecting our gross margins, outsourcing of manufacturing renders us relatively more dependent on the third-party manufacturers.



We completed the transfer of the manufacturing of our poultry diagnostic
products from our supplier to our manufacturing facilities in San Diego during the first quarter of 2002, although some of the lower-volume products were still awaiting licensure by the USDA. We believe that our gross margins on these products will
improve as we will have more products to absorb our fixed manufacturing costs.



Our research and development expenses decreased by $224,000 or 14% during 2002 as compared to 2001. This was due primarily to the decrease in research activities performed for us by third parties, and decreases in
patent legal expense. Our research and development expenses as a percentage of our net sales were 6% during 2002 and 2001.



Our selling and marketing expenses decreased by $1,306,000 or 23% during 2002 as compared to 2001. This was due to a concerted effort to reduce selling
and marketing expenses. Our selling and marketing expenses as a percentage of our net sales were 20% and 22% during 2002 and 2001, respectively.



Our general and administrative expenses increased by $2,526,000 or 40% during 2002 as compared to 2001. The increase is primarily due to $3,682,000 of
retention bonuses that became payable upon the consummation of the January 2002 Redwood preferred stock investment transaction, the severance costs related to the July 2002 termination of the President of SBIO-E and the severance costs related to
the September 2002 resignations of our Chief Executive Officer and Chief Financial Officer, and offset by the fact that goodwill is no longer amortized. Our general and administrative expenses as a percentage of our net sales were 41% and 24% during
2002 and 2001, respectively. Excluding the first quarter 2002 bonus expense and the goodwill amortization during 2001, our general and administrative expenses would have been $5,090,000 and $4,801,000 during 2002 and 2001, respectively, or 24% and
19% of our net sales during 2002 and 2001, respectively.



Our
net interest expense decreased by $268,000 or 29% during 2002 as compared to 2001. This was due to the decrease in the prime rate during 2002 and 2001, and decreases in the outstanding principal balance of our bank loan.



We recognized a provision for income taxes of $7,000 during 2002 as compared
to a provision for income taxes of $10,000 during 2001. The change in our ownership resulting from the January 2002 Redwood transaction limits the utilization of both Federal and state net operating loss carryforwards to $59,000 per year. As a
result of this limitation, $15,999,000 of our Federal net operating loss carryforwards, and $969,000 of our state net operating loss carryforwards, may expire before they can be utilized.



At the end of the third quarter of 2002, we began implementing a cost reduction program, which included a reduction in our
headcount.



We disposed of two unprofitable business lines in
2002. In August 2002, we sold our instrument manufacturing operations, located in Rome, New York, to Danam Acquisition Corp., located in Dallas, Texas, in exchange for a $500,000 note receivable. The note is payable, beginning in September 2002, in
60 monthly principal payments of $8,000 plus interest at 5%, is secured by the assets of the disposed operations (all of which we had been previously written off), and is guaranteed by Drew Scientific Group PLC (the parent of Danam Acquisition
Corp.) In November 2002, we terminated the license agreement for our PennHIP® operations,

located in Malvern, Pennsylvania, and transferred all of the assets related to the PennHIP® operations to the University of Pennsylvania. No consideration was received for the
transferred assets. We recorded the $500,000 sale price for the instrument manufacturing operations in, and we have restated prior amounts related to the disposed operations as, discontinued operations. See Note 4 to our consolidated financial
statements in Item 8 for a reconciliation of the restated amounts for the year ended December 31, 2001.



As of January 1, 2002, we adopted Statement of Financial Accounting Standards No. 142 (FAS 142), Goodwill and Other Intangible
Assets. FAS 142 changed the accounting for goodwill from an amortization method to an impairment-only approach. Under FAS 142, goodwill is tested annually and whenever events or circumstances occur indicating that goodwill might be impaired.
Upon adoption of FAS 142, amortization of goodwill recorded for business combinations consummated prior to July 1, 2001 ceased. In connection with the adoption of FAS 142, we performed a transitional goodwill impairment assessment. As a result of
this impairment assessment, we recorded an impairment of $7,756,000 which is classified as a cumulative effect of a change in accounting principle in the first quarter of 2002. We perform subsequent impairment assessments, at a minimum, in the
fourth quarter of each year; and subsequent impairments, if any, are classified as an operating expense. Our measurement of fair value upon adoption of FAS 142 was based upon a fairness opinion prepared by an independent investment
advisor in conjunction with the Redwood transaction. Our measurement of fair value for subsequent impairment assessments is the market price of our common stock on the date the assessment is performed. As a result of decreases in the market price of
our common stock during 2002, we recorded an impairment loss of $2,877,000 in the fourth quarter of 2002.



As of January 1, 2002, we adopted Statement of Financial Accounting Standards No. 144 Accounting for the Impairment or Disposal of Long-Lived
Assets (FAS 144). FAS 144 supersedes FAS 121 Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of. FAS 144 applies to all long-lived assets (including discontinued operations)
and consequently amends Accounting Principles Board Opinion No. 30 (APB 30), Reporting Results of Operations - Reporting the Effects of Disposal of a Segment of a Business. FAS 144 develops one accounting model for long-lived
assets that are to be disposed of by sale. FAS 144 requires that long-lived assets that are to be disposed of by sale be measured at the lower of book value or fair value less cost to sell. Additionally, FAS 144 expands the scope of discontinued
operations to include all components of an entity with operations that (1) can be distinguished from the rest of the entity and (2) will be eliminated from the ongoing operations of the entity in a disposal transaction. The adoption of FAS 144 did
not have a material impact on our financial position or results of operations.

Our bank loan came due
in January 2004; we did not pay it when it came due, and as of March 31, 2004, we had an outstanding principal balance on the note of $4,700,000. We will have to extend or restructure the note with the bank or refinance it with another lending
source. The bank had informally reduced the monthly principal payments to $30,000 for the payments due February 1, 2004, and March 1, 2004. On March 29, 2004, we entered into a forbearance agreement with the bank whereby the bank agreed not to
exercise any of its rights under the credit agreement through May 5, 2004, and agreed to formally reduce the monthly principal payments to $30,000 for the payments due April 1, 2004, and May 1, 2004; the forbearance agreement has now expired. We
believe we will be able to restructure or refinance the bank debt and it is absolutely essential to us that we do so. However, no assurance can be given that we will be successful in this effort to restructure or refinance the bank debt. Our bank
has given us no commitment that it will formally extend or refinance the loan.

Our loan has been handled by the banks workout department since 2001. We have, however, with the
exception of the January 25, 2004, balloon payment, always made our monthly payments of principal and interest, which we hope will weigh in our favor. In each of the past three years we have repaid approximately $1,200,000 of principal on the note.



We have positive cash flow from operations. Nonetheless, we
may require additional financing in the future, even if our bank loan situation is resolved. There can be no assurance that such financing would be available to us on favorable terms, or at all. Because our stock price is low, any equity financing
would significantly dilute current shareholders.



Our
operations are seasonal due to the sales of our canine heartworm diagnostic products. Our sales and profits tend to be concentrated in the first half of the year, as our distributors prepare for the heartworm season by purchasing diagnostic products
for resale to veterinarians. The operations of SBIO-E have reduced our seasonality as sales of their large animal diagnostic products tend to occur evenly throughout the year. In addition, sales of our SCA 2000 instruments and supplies and our poultry diagnostic products reduce our seasonality.



Certain Risk Factors



Our future operating results are subject to a number of factors, including:



In addition to the necessity of extending or refinancing our bank loan
which matured in January 2004, we may need additional capital in the future



Our bank loan came due in January 2004; we did not pay it when it came due, and as of March 31, 2004, we had an outstanding principal balance on the note of $4,700,000. We will have to restructure the note with the
bank or refinance it with another lending source. The bank had informally reduced the monthly principal payments to $30,000 for the payments due February 1, 2004, and March 1, 2004. On March 29, 2004, we entered into a forbearance agreement with the
bank whereby the bank agreed not to exercise any of its rights under the credit agreement through May 5, 2004, and agreed to formally reduce the monthly principal payments to $30,000 for the payments due April 1, 2004, and May 1, 2004; the
forbearance agreement has now expired. We believe we will be able to restructure or refinance the bank debt. However, no assurance can be given that we will be successful in this effort to restructure or refinance the bank debt. We may also need to
raise additional funds if our estimates of revenues, working capital and/or capital expenditure requirements change or prove inaccurate or in order for us to respond to unforeseen technological or marketing hurdles or to take advantage of
unanticipated opportunities.



Further, our future capital
requirements will depend on many factors beyond our control or ability to accurately estimate, including continued scientific progress in our product 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. Such funds may not
be available at the time or times needed, or available on terms acceptable to us. If adequate funds are not available, or are not available on acceptable terms, we may not be able to take advantage of market opportunities, to develop new products,
or to otherwise respond to competitive pressures. This inability could materially harm our business.



If we are unable to successfully reintroduce to the market the Witness® products which were previously manufactured by Agen, it could also hinder our ability to restructure or refinance our
bank loan, or obtain any other necessary additional capital.



We may be
unable to successfully reintroduce our key Witness®
products



Agen was the contract manufacturer of certain of
our Witness® in-clinic diagnostic products,
representing 38% of our 2002 net sales. Agen ceased supplying these products in April 2003. We have licensed the alternate-



11

##### Table of Contents

source Witness® canine heartworm product with the USDA (now to be supplied by another contract manufacturer), and we began selling this product in January 2004. We also anticipate having the
alternate-source Witness® feline leukemia and
canine parvovirus products available for sale late in the second quarter of 2004. In addition to the risks that the alternate-source products will be delayed, will experience quality issues, cannot be supplied reliably, etc., we cannot ensure that
after our products have been off the market for several months we will necessarily be able to regain our previous market share and our previous price points.



The market in which we operate is intensely competitive, even with regard to our key canine heartworm diagnostic products, and many of our competitors are larger and
more established, and we are facing unfair competition from Agen in this market



The market for animal health care products is extremely competitive. Companies in the animal health care market compete to develop new products, to market and manufacture products efficiently, to implement effective
research strategies, and to obtain regulatory approval. Our current competitors include IDEXX Laboratories, a significantly larger company, Heska Corporation and Agen. These companies may have greater financial, manufacturing, marketing, and
research resources than we do. In addition, IDEXX Laboratories prohibits its distributors from selling competitors products, including ours. Further, additional competition could come from new entrants to the animal health care market. We
cannot assure you that we will be able to compete successfully in the future or that competition will not harm our business.



Our canine heartworm diagnostic products constituted 24% of our sales for the year ended December 31, 2003. In addition to our historic competition with
IDEXX Laboratories, the sales leader in this product category, our sales have been substantially affected since 1999 by a heartworm product from Heska. Agen has entered this market too (with, we believe, a product which infringes our heartworm
patent). Additional competition, including erosion of the average selling price, from Agen in this key market with this product has seriously damaged us. Even if we prevail against Agen in our patent litigation, we could face renewed competition
from Agen or other new competitors when our U.S. heartworm patent expires in December 2005.



As previously mentioned, as a result of Agen ceasing to contract manufacture our Witness® products we believe that our sales could be materially adversely affected in 2004 and beyond if we are unable to successfully reintroduce the
alternate-source products into the market. The Witness® products previously contract manufactured by Agen represented 38% of our net sales for the year ending December 31, 2002. There can be no assurances that we will be able to achieve our previous sales levels of these
in-clinic products.



We have a history of losses and an accumulated deficit



Although we were profitable in 2003 and 2001, we did not
achieve profitability for the year ended December 31, 2002, and we have had a history of annual losses. We have incurred a consolidated accumulated deficit of $45,146,000 at December 31, 2003. We may not achieve annual profitability again, and if we
are profitable in the future there can be no assurance that profitability can be sustained.



We rely on third party distributors for a substantial portion of our sales



We have historically depended upon distributors for a large portion of our sales, and we may not have the ability to establish and maintain an adequate
independent sales and marketing capability in any or all of our targeted markets. Distributor agreements render our sales exposed to the efforts of third parties who are not employees of Synbiotics and over whom we have no control. Their failure to
generate significant sales of our products could materially harm our business. Reduction by these distributors of the quantity of our products which they distribute would materially harm our business. Also, the distributors are not bound to us by
long-term agreements, and a decision by any major distributor to stop doing business with us could materially hurt our revenues. IDEXX Laboratories prohibition against its distributors carrying competitors products, including ours, has
made, and could continue to make, some distributors unavailable to us. In the past, we have lost major distributors to IDEXX Laboratories.

We depend on key executives and personnel, but we have experienced executive turnover



Our future success will depend, to a significant extent, on the ability of
our management to operate effectively, both individually and as a group. Competition for qualified personnel in the animal health care products industry is intense, and we may not be successful in attracting and retaining such personnel. There are
only a limited number of persons with the requisite skills to serve in those positions and it may become increasingly difficult to hire such persons. The loss of the services of any of our key personnel or the inability to attract or retain
qualified personnel could harm our business. At the end of the third quarter of 2002, our chief executive officer and our chief financial officer both resigned. We replaced our chief financial officer by promoting our corporate controller, and we
hired Paul Hays, our new president, at the end of December 2002. In May 2003, we hired Kent Luther, our new vice president of sales and marketing, to replace our former vice president who resigned in April 2003.



We depend on third party manufacturers, and may experience problems in obtaining supplies
of our key products



We contract for the manufacture of
some of our products, including our Witness®
in-clinic canine heartworm, feline leukemia, and canine parvovirus diagnostic products and our SCA 2000 instrument products. We also expect that some of our anticipated new products will be manufactured by third parties. In addition, some of the products manufactured for us by third
parties are licensed to us by their manufacturers. There are a number of risks associated with our dependence on third-party manufacturers including:



| |  |  | the potential for a decision by the manufacturer to cease supplying us and/or to make and market competing products;
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | reduced control over delivery schedules;
| | - |  | ----------------------------------------



| |  |  | quality assurance;
| | - |  | ------------------



| |  |  | manufacturing yields and costs;
| | - |  | -------------------------------



| |  |  | whether the manufacturer maintains financial and operational stability;
| | - |  | -----------------------------------------------------------------------



| |  |  | the potential lack of adequate capacity during periods of excess demand;
| | - |  | ------------------------------------------------------------------------



| |  |  | limited warranties on products supplied to us;
| | - |  | ----------------------------------------------



| |  |  | increases in prices and the potential misappropriation of our intellectual property; and
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | limited negotiating leverage in the event of disputes with the third-party manufacturers.
| | - |  | -----------------------------------------------------------------------------------------



If our third party manufacturers fail to supply us with an adequate number of finished products, our business would be
significantly harmed. We have no long-term contracts or arrangements with any of our vendors that guarantee product availability, the continuation of particular payment terms or the extension of credit limits.



If we encounter delays or difficulties in our relationships with our
manufacturers, the resulting problems could have a material adverse effect on us.



As mentioned above, Agen, the previous contract manufacturer of certain of our Witness® in-clinic products, ceased to supply us with those products, and entered the market with competing products.



We rely on new and recent products



We rely to a significant extent on new and recently developed products, and
expect that we will need to continue to introduce new products to be successful in the future. There can be no assurance that we will obtain and maintain market acceptance of our products. There can be no assurance that future products, including
our alternate-source in-clinic diagnostic products, will meet applicable regulatory standards, be capable of being produced in commercial quantities at acceptable cost or be successfully commercialized.



13



---

##### Table of Contents

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



Our canine heartworm business is seasonal



Our operations are seasonal due to the timing of sales of our canine heartworm diagnostic products. Our sales and profits tend to be concentrated in the first half of the year as our distributors prepare for the
heartworm season by purchasing diagnostic products for resale to veterinarians. One effect of this is a need to devote large amounts of cash to building canine heartworm diagnostic products inventory in preparation for the canine heartworm selling
season at a time when our working capital is relatively low.



Any failure to
adequately establish or protect our proprietary rights may adversely affect us



We rely on a combination of patent, copyright, and trademark laws, trade secrets, and confidentiality and other contractual provisions to protect our proprietary rights. These measures afford only limited protection.
We currently have 13 issued U.S. patents and one pending patent application. Our means of protecting our proprietary rights in the U.S. or abroad may not be adequate and competitors may independently develop similar technologies. Our future success
will depend in part on our ability to protect our proprietary rights and the technologies used in our principal products. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or to
obtain and use trade secrets or other information that we regard as proprietary. In addition, the laws of some foreign countries do not protect our proprietary rights as fully as do the laws of the United States. Issued patents may not preserve our
proprietary position. Even if they do, competitors or others may develop technologies similar to or superior to our own. If we do not enforce and protect our intellectual property, our business will be harmed. From time to time, third parties,
including our competitors, have asserted patent, copyright, and other intellectual property rights to technologies that are important to us. We expect that we will increasingly be subject to infringement claims as the number of products and
competitors in the animal health care market increases.



The
results of any litigated matter are inherently uncertain. In the event of an adverse result in any litigation with third parties that could arise in the future, we could be required to:



| |  |  | pay substantial damages, including treble damages if we are held to have willfully infringed;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | cease the manufacture, use and sale of infringing products;
| | - |  | -----------------------------------------------------------



| |  |  | expend significant resources to develop non-infringing technology; or
| | - |  | ---------------------------------------------------------------------



| |  |  | obtain licenses to the infringing technology.
| | - |  | ---------------------------------------------



Licenses may not be available from any third party that asserts intellectual property claims against us on commercially reasonable terms, or at all.



Also, litigation is costly regardless of its outcome and can
require significant management attention.



Agen has introduced
into the U.S. market a canine heartworm diagnostic product which is essentially identical to our Witness® canine heartworm diagnostic test kit, including our patented biological components. In September 2003, we filed a patent infringement lawsuit against Agen claiming that Agen has
willfully infringed our U.S. Patent No. 4,789,631 pertaining to heartworm detection technology. In addition to seeking damages, we are asking for an injunction against Agen, preventing Agen from importing, selling or offering for sale their canine
heartworm diagnostic test kit in the United States. On March 15, 2004, the Court issued a temporary restraining order against Agen, preventing Agens canine heartworm diagnostic product from entering the United States market. The Court ordered
that Agen, their directors, officers, employees, agents, servants, and all those in



14

##### Table of Contents

active concert or participation with them, are restrained from importing, making, using, selling, or offering for sale, in the United States, any canine
heartworm kit containing the DI 16 872.5 monoclonal antibody manufactured or supplied by Agen. The Court ruled earlier that we were likely to succeed on the merits of our claim that Agens canine heartworm diagnostic product,
STATScreenTMCHW, which contains our DI 16 872.5 monoclonal antibody, infringed our United States Patent 4,789,631.
A preliminary injunction hearing was held on April 15, 2004, and on April 21, 2004, the Court denied our motion and dissolved the temporary restraining order. In conjunction with the temporary restraining order, we were required to post a $250,000
bond; the Court has not yet released the bond. The lawsuit is currently in the discovery stage, and a trial date is scheduled for June 28, 2004.



In September 2003, Agen filed a lawsuit against us, in the U.S. District Court for the Northern District of California, asking for a declaratory judgment
that Agens canine heartworm diagnostic test kit does not infringe our U.S. Patent No. 4,789,631 pertaining to heartworm detection technology, and also asking for a declaratory judgment that Claim 5 of our U.S. Patent No. 4,789,631 is invalid.
We filed a motion to transfer the lawsuit to the U.S. District Court for the Southern District of California. On November 7, 2003, our motion was granted and the case was transferred.



Should Agen prevail in either of these lawsuits, our future sales of canine heartworm diagnostics products in general, and
especially our Witness® canine heartworm diagnostic
product, may be materially adversely affected due to market competition from Agens product. Additionally, we will be incurring material litigation expenses.



Also, because our patents and patent applications cover novel diagnostic approaches:



| |  |  | the patent coverage which we receive could be significantly narrower than the patent coverage we seek in our patent applications; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our patent positions involve complex legal and factual issues which can be hard for patent examiners or lawyers asserting patent coverage to successfully resolve.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



Because of this, our patent position could be
vulnerable and our business could be materially harmed. In any event, our important United States canine heartworm diagnosis patent will expire in December 2005.



The U.S. patent application system also exposes us to risks. In the United States, the first party to make a discovery is
granted the right to patent it and patent applications are generally maintained in secrecy for 18 months. For these reasons, we can never know if we are the first to discover particular technologies. Therefore, we can never be certain that our
technologies will be patented and we could become involved in lengthy, expensive, and distracting disputes concerning whether we were the first to make the disputed discovery. Any of these events would materially harm our business.



Our business is regulated by the United States and various foreign governments



Our business is subject to substantial regulation by the
United States government, most notably the United States Department of Agriculture, and the French government. In addition, our operations may be subject to future legislation and/or rules issued by domestic or foreign governmental agencies with
regulatory authority relating to our business. There can be no assurance that we will continue to be in compliance with any of these regulations.



For marketing outside the United States, we and our suppliers are subject to foreign regulatory requirements, which vary widely from country to country.
There can be no assurance that we and our suppliers will meet and sustain compliance with any such requirements.



We use hazardous materials



Our business requires that we store and use hazardous materials and chemicals. Although we believe that our procedures for storing, handling, and
disposing of these materials comply with the standards prescribed by local, state, and federal regulations, the risk of accidental contamination or injury from these materials cannot be



15

##### Table of Contents

completely eliminated. If any of these materials were mishandled, or if an accident with them occurred, the consequences could be extremely damaging and we
could be held liable for them. Our liability for such an event would materially harm our business and could exceed all of our available resources for satisfying it.



Item 7A.    Quantitative and Qualitative Disclosures About Market Risk



Our market risk consists primarily of the potential for changes in interest rates and foreign currency exchange rates.



Interest Rate Risk



The fair value of our interest bearing debt at December 31, 2003 was $4,804,000, which has a variable interest rate based on
the prime rate.



A change in interest rates of five percentage
points would have a material impact on our financial condition, results of operations and cash flows as it relates to our variable rate debt. In addition, if interest rates increased by five percentage points our ability to refinance our bank debt
would be seriously compromised.



Foreign Currency Exchange Rate Risk



Our foreign currency exchange rate risk relates to the
operations of SBIO-E as it transacts business in Euros, its local currency. However, this risk is limited to our intercompany receivable from SBIO-E and the conversion of its financial statements into the U.S. dollar for consolidation. There is no
foreign currency exchange rate risk related to SBIO-Es transactions outside of the European Union as those transactions are denominated in Euros and, to a lesser extent, U.S. dollars. Similarly, all of the foreign transactions of our U.S.
operations are denominated in U.S. dollars. We do not hedge our cash flows on intercompany transactions, nor do we hold any other derivative securities or hedging instruments based on currency exchange rates. As a result, the effects of a 5% change
in exchange rates would have a material impact on our financial condition, results of operations and cash flows, but only to the extent that it relates to the conversion of SBIO-Es financial statements, including its intercompany payable, into
the U.S. dollar for consolidation. For the year ended December 31, 2003, 40% of our net sales were net sales of SBIO-E.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM



To the Board of Directors

and Shareholders of

Synbiotics Corporation



We have audited the
consolidated financial statements listed in the accompanying index of Synbiotics Corporation and its subsidiary as of December 31, 2003 and 2002, and for each of the years in the three year period ended December 31, 2003. 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 conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards 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. 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 audits provide a reasonable basis for
our opinion.



In our opinion, the financial statements referred
to above present fairly, in all material respects, the consolidated financial position of Synbiotics Corporation and its subsidiary as of December 31, 2003 and 2002, and the consolidated results of their operations and their cash flows for each of
the years in the three year period ended December 31, 2003 in conformity with accounting principles generally accepted in the United States of America.



The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern. As discussed in Note 2 to the
consolidated financial statements, the Company has an accumulated deficit of $45,146,000, and has a note payable of $4,804,000 which was payable in full on January 25, 2004, and was not paid in full. These factors, among others, raise substantial
doubt about its ability to continue as a going concern. Managements plans in regards to these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this
uncertainty.

NOTES TO
CONSOLIDATED FINANCIAL STATEMENTS



NOTE 1SIGNIFICANT ACCOUNTING
POLICIES:



The Company



Synbiotics Corporation (the Company), incorporated in 1982,
develops, manufactures and markets diagnostic products for animals. The Companys principal markets are veterinary practices, laboratories and poultry producers in the United States, Canada, Europe, Africa, Asia, Oceania and Latin America. The
Companys products are sold primarily to wholesale distributors, and also directly to veterinarians, laboratories and poultry producers.



Principles of Consolidation



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



Trade Accounts Receivable



Trade accounts receivable are stated at the amount management expects to collect from outstanding balances. Management provides for probable uncollectible amounts through a charge to earnings and a credit to a valuation allowance based on
its assessment of the current status of individual accounts. Balances that are still outstanding after management has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to trade accounts
receivable. Changes in the valuation allowance have not been material to the financial statements.



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.



Goodwill and Other Intangible Assets



As of January 1, 2002, the Company adopted Statement of Financial Accounting Standards No. 142 (FAS 142), Goodwill and Other Intangible
Assets. FAS 142 changed the accounting for goodwill from an amortization method to an impairment-only approach. Under FAS 142, goodwill is tested annually and whenever events or circumstances occur indicating that goodwill might be impaired.
In connection with the adoption of FAS 142, the Company performed a transitional goodwill impairment assessment. As a result of this impairment assessment, in the first quarter of 2002 the Company recorded an impairment loss of $7,756,000 which is
classified as a cumulative effect of a change in accounting principle for the year ended December 31, 2002. Subsequent impairment assessments will be performed, at a minimum, in the fourth quarter of each year; and subsequent impairments, if any,
will be classified as an operating expense. The Companys measurement of fair value upon adoption was based upon a fairness opinion prepared by an independent investment advisor in conjunction with the Redwood transaction (Note 3).
The Companys measurement of fair value for subsequent impairment assessments will be the market price of the Companys common stock on the date the assessment is performed.

SYNBIOTICS CORPORATION



NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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



Long-Lived Assets



As of January 1, 2002, the Company adopted Statement of Financial Accounting
Standards No. 144 Accounting for the Impairment or Disposal of Long-Lived Assets (FAS 144). FAS 144 supersedes FAS 121 Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of. FAS 144 applies to all long-lived assets (including discontinued operations) and consequently amends Accounting Principles Board Opinion No. 30 (APB 30), Reporting Results of OperationsReporting the Effects of
Disposal of a Segment of a Business. FAS 144 develops one accounting model for long-lived assets that are to be disposed of by sale. FAS 144 requires that long-lived assets that are to be disposed of by sale be measured at the lower of book
value or fair value less cost to sell. Additionally, FAS 144 expands the scope of discontinued operations to include all components of an entity with operations that (1) can be distinguished from the rest of the entity and (2) will be eliminated
from the ongoing operations of the entity in a disposal transaction. The adoption of FAS 144 did not have a material impact on the Companys financial position or results of operations.



Fair Value of Financial Instruments



The carrying amounts for cash and cash equivalents at December 31, 2003 and
2002 approximate their fair values. The carrying amount of the debt approximates fair value at December 31, 2003 and 2002 as the variable interest rate on the debt approximates current market rates of interest.



Translation of Financial Statements



The financial statements for SBIO-E whose functional currency is the Euro
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 title and risk
of loss transfers to the customer. Amounts charged to customers for shipping and handling are included in net sales, and shipping and handling costs are included in cost of sales. The Company provides promotional discounts and rebates to certain of
its distributors. Based upon the structure of these rebate programs and the Companys past history, the Company is able to accurately estimate the amount of rebates at the time of sale. These rebates are recorded as a reduction of net sales.
License fee revenue is recognized ratably over the license term when the Company has a further performance obligation to the licensee. In the event that the Company has no further performance obligation to the licensee, license fee revenue is
recognized upon receipt.



Advertising Costs



The Company recognizes the costs of advertising at the time such charges are
incurred. Advertising expense totaled $342,000, $338,000 and $348,000 during the years ended December 31, 2003, 2002, and 2001, respectively.

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 2003 and 2002, respectively: dividend yield of 0% for both
years; expected volatility of 148.1% and 121.3%; risk-free interest rates of 2.1% and 3.1%; and expected lives of 3.7 years for both years. There were no stock option grants during 2001.



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. The effect of tax rate changes are reflected in income during the period such changes are
enacted.



Net Income (Loss) Per Share



Basic net income (loss) per share is computed as net income (loss) less
cumulative preferred stock dividends divided by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed as net income (loss) divided by the weighted average number of common shares
and potential common shares, using the treasury stock method, outstanding during the period (Note 12).

Cash and Equivalents



Cash and equivalents include cash investments which are highly liquid and have an original maturity of three months or less.



Use of Estimates



The preparation of financial statements in conformity with accounting principles generally accepted in the United States
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.



Comprehensive Income (Loss)



Comprehensive
income (loss) is defined as the change in equity (net assets) of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. It includes all changes in equity during a period except those
resulting from investments by owners and distributions to owners. The Company reports in the financial statements, in addition to net income (loss), comprehensive income (loss) and its components including foreign currency items.



Segment Reporting



Operating segments are determined consistent with the way that management organizes and evaluates financial information
internally for making operating decisions and assessing performance. The Company operates in one segment.



Concentrations of Risk



The Company relies on a third party for the manufacture of certain of its canine heartworm diagnostic products. The Company has the right to manufacture these products in the event that the third party is unable to supply these products.
However, the regulatory process involved in transferring the manufacturing may cause a delay in the manufacturing and a possible loss of sales, which may affect operating results adversely.



NOTE 2GOING CONCERN:



The accompanying consolidated financial statements have been prepared on a
going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As shown in the consolidated financial statements, although profitable in 2003, during 2002 the Company incurred
a net loss of $14,401,000, and had an accumulated deficit of $45,146,000 as of December 31, 2003.



As of December 31, 2003, the Company had an outstanding principal balance under its bank debt totaling $4,804,000 (Note 8), all of which was due and
payable in January 2004. As of March 31, 2004, there was an unpaid balance on the note of $4,700,000. The bank had informally reduced the monthly principal payments to $30,000 for the payments due February 1, 2004, and March 1, 2004. On March 29,
2004, the Company entered into a forbearance agreement with the bank whereby the bank agreed not to exercise any of its rights under the credit agreement through May 5, 2004, and agreed to formally reduce the monthly principal payments to $30,000
for the payments due April 1, 2004, and May 1, 2004; the forbearance agreement has now expired. The Company believes it will be able to restructure or refinance the bank debt. However, no assurance can be given that the Company will be successful in
this effort to obtain an extension from the bank or to restructure or refinance the bank debt. The Companys resources do not enable it to repay the note in its entirety immediately, unless the note were to be refinanced with another lender.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



These factors raise substantial doubt about the Companys ability to continue as a going concern
for a reasonable period of time. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be
necessary should the Company be unable to continue as a going concern.



NOTE
3ISSUANCE OF PREFERRED STOCK AND RESTRUCTURING OF DEBT:



In January 2002, the Company issued 2,800 shares of Series B Preferred Stock to Redwood West Coast, LLC (Redwood) in exchange for $2,800,000 cash, less $196,000 of issuance costs (Note 10). Redwood representatives now constitute
67% of the Companys Board of Directors, and Redwood also controls approximately 57% of the Companys voting stock on a fully diluted basis. The Company agreed to pay an affiliate of Redwood a consulting fee of $15,000 per month beginning
in February 2002. In October 2002, the Company entered into a Stock Swap Agreement with Redwood whereby the Company issued 2,800 shares of Series C Preferred Stock to Redwood in exchange for Redwoods 2,800 shares of Series B Preferred (Note
10).



In January 2002, in conjunction with the Redwood
transaction, the Company amended cash retention bonus agreements with certain employees (the Converted Retention Bonuses) so that, instead of cash, the employees received, on May 15, 2002, an aggregate of 8,255,000 shares of the
Companys common stock under the 1995 Stock Option/Stock Issuance Plan. The Company also agreed to pay the employees income tax withholding obligation related to the Converted Retention Bonuses in exchange for the cancellation of options
outstanding for an aggregate of 880,000 shares of the Companys common stock. In January 2002, the Company recorded compensation expense, including the employees income tax withholding obligation, related to the Converted Retention
Bonuses totaling $3,029,000. In addition, the Company also amended its remaining employee cash retention bonus agreements (the Cash Retention Bonuses) so that the amounts that would have become payable upon the consummation of the
Redwood transaction would instead be payable in January 2003, and were paid in December 2002. The Company recorded compensation expense totaling $653,000 in January 2002 related to the Cash Retention Bonuses. The Cash Retention Bonuses also modified
options to purchase an aggregate of 72,000 shares of the Companys common stock to provide for immediate vesting, upon consummation of the Redwood transaction, and to extend the expiration date to January 25, 2004. No compensation expense was
recorded related to these modifications as the exercise prices of all of the options involved was greater than the fair market value of the shares on the modification date.



The Company amended its credit agreement with Comerica BankCalifornia (Comerica) in conjunction with the
Redwood transaction. The $7,132,000 principal amount then outstanding under the Companys revolving line of credit and term note, which was due in March 2002, was converted into a new $7,132,000 term note (Note 8).



NOTE 4DISCONTINUED OPERATIONS:



In August 2002, the Company sold its instrument manufacturing operations,
located in Rome, New York, to Danam Acquisition Corp., located in Dallas, Texas, in exchange for a $500,000 note receivable. The note is payable, beginning in September 2002, in 60 monthly principal payments of $8,000 plus interest at 5%, is secured
by the assets of the disposed operations (all of which had been previously written off by the Company), and is guaranteed by Drew Scientific Group PLC (the parent of Danam Acquisition Corp.) The Company has recorded the $500,000 gain in discontinued
operations.



In November 2002, the Company terminated the
license agreement for its PennHIP® operations,
located in Malvern, Pennsylvania, and transferred all of the assets related to the PennHIP® operations to the University of Pennsylvania. No consideration was received for the transferred assets.

NOTE 5PATENT LITIGATION
SETTLEMENT:



In November 1998, the Company filed a lawsuit
against Heska Corporation in the United States District Court for the Southern District of California alleging that Heska infringed a patent owned by the Company relating to heartworm diagnostic technology. In March 2003, the Company and Heska
entered into settlement and license agreements which resolved all outstanding claims in the lawsuit. As part of those agreements, each party licensed certain intellectual property rights from the other party, including Heska licensing from the
Company the patent relating to the heartworm diagnostic technology. In addition, the Company received $250,000 in April 2003, will receive $265,000 in 24 monthly installments of $11,000 beginning in January 2004 and is receiving royalty payments on
sales of licensed canine heartworm diagnostic products beginning April 2003. As a result, the Company has recorded a one-time credit to operating expenses totaling $515,000 during the year ended December 31, 2003.

NOTE 7GOODWILL AND OTHER
INTANGIBLES:



On January 1, 2002, the Company adopted FAS
142 (Note 1). As a result, in the first quarter of 2002 the Company recorded an impairment loss of $7,756,000 which is classified as a cumulative effect of a change in accounting principle, and ceased to amortize goodwill. In the fourth quarter of
2002, the Company performed its annual impairment assessment, and, as a result of decreases in the market price of the Companys common stock during 2002, recorded an additional impairment loss of $2,877,000. The fair value used in the annual
assessment was determined based upon the market price of the Companys common stock on December 31, 2002. Based upon the market price of the Companys common stock on December 31, 2003, there was no impairment loss resulting from the
annual impairment assessment in 2003.



The Company has
allocated all of its goodwill to its only reporting unit, which is also its only reportable segment (Note 14). Changes in the carrying amount of goodwill were as follows:

Amortization expense was $625,000 and $654,000 during the years ended December 31, 2003 and 2002,
respectively. The weighted-average amortization periods for patents and licenses are 9 years and 10 years, respectively, and the weighted-average amortization period for total intangible assets is 9 years. Annual pretax amortization for other
intangibles over the next five years is estimated to be as follows:

NOTE 8NOTE PAYABLE AND
LONG-TERM DEBT:



In January 2002, in conjunction with the
Redwood transaction (Note 3), the Company amended its credit agreement with the bank. The $7,132,000 principal amount outstanding under the Companys revolving line of credit and term note, each due in March 2002, was converted into a new
$7,132,000 term note. The new note bears interest at the rate of prime plus 2% (effectively 6% at December 31, 2003), was payable in monthly installments of $100,000 plus accrued interest through January 2003 and monthly installments of $125,000
plus accrued interest thereafter, with all remaining principal due January 25, 2004, and is secured by substantially all of the Companys assets. In September 2003, the Company entered into a Letter Agreement with the bank, effective August 1,
2003, reducing the Companys monthly principal payments from $125,000 to $45,000 from August 1, 2003 through January 1, 2004.



As of December 31, 2003, the Company had an outstanding principal balance under its bank debt totaling $4,804,000, all of which was due and payable in
January 2004. As of March 31, 2004, there was an unpaid balance on the note of $4,700,000. The bank had informally reduced the monthly principal payments to $30,000 for the payments due February 1, 2004, and March 1, 2004. On March 29, 2004, the
Company entered into a forbearance agreement with the bank whereby the bank agreed not to exercise any of its rights under the credit agreement through May 5, 2004, and agreed to formally reduce the monthly principal payments to $30,000 for the
payments due April 1, 2004, and May 1, 2004; the forbearance agreement has now expired. The Company believes it will be able to restructure or refinance the bank debt. However, no assurance can be given that the Company will be successful in this
effort to obtain an extension from the bank or to restructure or refinance the bank debt.



Interest paid during 2003, 2002 and 2001 totaled $334,000, $502,000 and $812,000, respectively.



NOTE 9MANDATORILY REDEEMABLE COMMON STOCK:



621,000 shares issued in conjunction with the 1997 acquisition of SBIO-E were subject to certain registration rights as well as put and call provisions.
As of December 31, 2001, the Company classified the shares on the balance sheet as mandatorily redeemable and had accreted the value of the shares to the put option price, using the interest method, with the accretion being charged directly to
retained earnings.



On June 1, 2001, the Company assigned its
feline leukemia virus vaccine distribution agreement with Intervet, Inc. to Merial Limited, Merial S.A.S. and Merial, Inc. (collectively Merial). In exchange, Merial waived its right to sell to the Company the above mentioned 621,000
shares of the Companys common stock at $5.00 per share (the Put Right). Merial also agreed to allow the Company to pay accrued royalties, under a

separate agreement, totaling $613,000 in ten monthly installments of $61,300 which began in July 2001. If the Company failed to meet its royalty payment
obligation, the Put Right would have reverted to Merial. When the final royalty payment was made in April 2002, and the Put Right was extinguished, the Company reclassified the mandatorily redeemable common stock to shareholders equity.



In March 1999, the Company amended its U.S. feline leukemia
virus vaccine supply agreement with Merial, and the Company received $1,453,000 which it was recognizing as license fee revenue ratably over the remaining life of the supply agreement. As the Company has assigned its distribution agreement with
Intervet, Inc. to Merial, the Company has no further contractual obligations under the supply agreement and recognized, in June 2001, the remaining $868,000 of deferred license fee revenue.



NOTE 10SHAREHOLDERS EQUITY:



In January 2002, in conjunction with the Redwood transaction (Note 3), the
Company amended cash retention bonus agreements with certain employees (the Converted Retention Bonuses) so that, instead of cash, the employees received, on May 15, 2002, an aggregate of 8,255,000 shares of the Companys common
stock under the 1995 Stock Option/Stock Issuance Plan. The Company also agreed to pay the employees income tax withholding obligation related to the Converted Retention Bonuses. In January 2002, the Company recorded compensation expense,
including the employees income tax withholding obligation, related to the Converted Retention Bonuses totaling $3,029,000.



On March 26, 2003, the Company declared a dividend on the Series C preferred stock totaling $213,000, for dividends accrued and payable as of January 31,
2003. On June 12, 2003, the Company declared a dividend on the Series C preferred stock totaling $53,000, for dividends accrued and payable as of April 30, 2003. Redwood, as permitted by the Certificate of Determination of the Series C preferred
stock, elected to receive shares of the Companys common stock in lieu of the cash dividends. As a result, 1,662,000 shares of the Companys common stock were issued to Redwoods distributees on March 26, 2003, and 409,000 shares of
the Companys common stock were issued to Redwoods distributees on June 12, 2003.



On March 11, 2004, the Company declared a dividend on the Series C preferred stock totaling $158,000, for dividends accrued and payable as of January 31, 2004. Redwood, as permitted by the Certificate of Determination
of the Series C preferred stock, elected to receive shares of the Companys common stock in lieu of the cash dividends. As a result, 354,000 shares of the Companys common stock were issued to Redwoods distributees on March 11, 2004.



Preferred Stock



The Company is authorized to issue up to 25,000,000 shares of preferred
stock. The preferred stock may be issued in one or more series. The Board of Directors is authorized to fix or alter the dividend rights, dividend rate, conversion rights, voting rights, rights and terms of redemption (including sinking fund
provisions), redemption price or prices, and the liquidation preferences of any wholly unissued series of preferred stock, and the number of shares constituting any such series and the designation thereof, or any of them; and to increase or decrease
the number of shares of any series subsequent to the issuance of shares of that series, but not below the number of shares of such series then outstanding. In case the number of shares of any series shall be so decreased, the shares constituting
such decrease shall resume the status that they had prior to the adoption of the resolution originally fixing the number of shares of such series.

Series A Preferred Stock



The Company has a Series A Junior Participating Preferred Stock (the Series A Preferred) consisting of 200,000
shares. Each share of Series A Preferred is entitled to 1,000 votes. Each Series A Preferred share is entitled to dividends, payable in cash quarterly, in an amount equal to 1,000 times the aggregate per share amount of dividends declared on the
common stock. In the event that no common stock dividends are declared, each share of Series A Preferred is entitled to $.001 per share. The Series A Preferred is entitled to a liquidation preference of $1,000 per share, plus accrued and unpaid
dividends; provided, however, that each Series A Preferred share is entitled to receive an aggregate amount per share equal to 10,000 times the aggregate amount per share distributed to the holders of common stock. In the event of a consolidation,
merger, combination, etc., each share of Series A Preferred shall be exchanged into 1,000 times the aggregate per share consideration of the common stock.



There were no shares of Series A Preferred issued and outstanding as of December 31, 2003 and 2002.



Series A Preferred Stock Purchase Rights



As part of the Companys implementation of a poison pill
shareholder rights plan, the Company issued preferred share purchase rights (the Rights) to purchase, for $10.00 (the Purchase Price), 1/1000th of a share of Synbiotics Series A Preferred (the Unit). The
Rights are not exercisable until the earlier to occur of (i) a public announcement that beneficial ownership of 20% or more of the Companys outstanding common stock has been acquired or (ii) 10 business days (or a later date as determined by
the Board of Directors) following the commencement of, or announcement of an intention to make, a tender offer or exchange offer to acquire beneficial ownership of 20% or more of the outstanding common stock of the Company.



At any time after the beneficial ownership of 20% or more of the outstanding
shares of the Companys common stock has been acquired (but before the acquiring party has acquired 50% of the outstanding common stock) the Company may exchange all or part of the Rights for Units at an exchange ratio equal to (subject to
adjustment to reflect stock splits, stock dividends and similar transactions) the Purchase Price divided by the then current per share market price per Unit on the Distribution Date. In January 2002, in conjunction with the Redwood transaction (Note
3), the rights plan was amended so that the Rights would not be exercisable upon the consummation of the Redwood transaction.



At any time prior to the public announcement that the beneficial ownership of 20% or more of the outstanding common stock of the Company has been
acquired, the Company may redeem the Rights in whole, but not in part, at a price of $0.001 per Right (the Redemption Price). The redemption of the rights will be effective at such time as the Board of Directors in its sole discretion
may establish.



The Rights will expire on October 7, 2008,
unless the expiration date is extended or unless the Rights are earlier redeemed or exchanged by the Company.



Series B Preferred Stock



In January 2002, in conjunction with the Redwood transaction (Note 3), the Company designated and authorized 4,000 shares of Series B Preferred Stock (the Series B Preferred). In January 2002, the Company issued to Redwood 2,800
shares of Series B Preferred in exchange for $2,800,000 cash. In October 2002, the Company entered into a Stock Swap Agreement with Redwood whereby the Company issued 2,800 shares of Series C Preferred Stock to Redwood in exchange for Redwoods
2,800 shares of Series B Preferred.

Series C Preferred Stock



In October 2002, the Company designated and authorized 4,000 shares of Series C Preferred Stock (the Series C
Preferred), and entered into a Stock Swap Agreement with Redwood whereby the Company issued 2,800 shares of Series C Preferred to Redwood in exchange for Redwoods 2,800 shares of Series B Preferred. Each Series C Preferred share is
entitled to cumulative dividends, payable in cash quarterly (although an election can be made to receive the dividends in shares of the Companys common stock in the event the dividends are not paid within 30 days), in an annual amount of $75
per share; each Series C Preferred share is also entitled to, in effect, the dividends which had accumulated on a corresponding Series B Preferred share before the time of the swap. The Series C Preferred is entitled to a liquidation preference of
$1,000 per share, plus accumulated and unpaid dividends. Each share of Series C Preferred has voting power equivalent to 7,785 shares of common stock. Each share of Series C Preferred is convertible into 7,785 shares of common stock (subject to
anti-dilution adjustments).



On March 26, 2003, the Company
declared a dividend on the Series C preferred stock totaling $213,000, for dividends accrued and payable as of January 31, 2003. On June 12, 2003, the Company declared a dividend on the Series C preferred stock totaling $53,000, for dividends
accrued and payable as of April 30, 2003. Redwood elected to receive shares of the Companys common stock in lieu of the cash dividends. As a result, 1,663,000 shares of the Companys common stock were issued to Redwoods distributees
on March 26, 2003, and 409,000 shares of the Companys common stock were issued to Redwoods distributees on June 12, 2003.



As of December 31, 2003, a cumulative dividend arrearage of $105,000 existed on the Companys Series C preferred stock.



Stock Warrants



In conjunction with a November 2000 amendment to its bank debt agreement, the Company issued to the bank a warrant to
purchase 250,000 shares of the Companys common stock at an exercise price of $2.00 per share. The warrant is exercisable at any time through November 30, 2007. The Company has valued the warrant at $32,000 using the Black-Scholes option
pricing model.



In conjunction with the 1997 acquisition of
SBIO-E, the Company issued to a financial institution a warrant to purchase 240,000 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 January 2002, in conjunction with the Redwood transaction (Note 3), the warrant was adjusted,
pursuant to its anti-dilution provisions, and is now exercisable into 343,000 shares of the Companys common stock at an exercise price of $0.007 per share.



Stock Option Plans



The Company adopted the 1995 Stock Option/Stock Issuance Plan (the 1995 Plan) whereby an aggregate of 2,600,000 shares of the Companys
common stock were initially reserved for issuance. 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 January
2002, in conjunction with the Redwood transaction (Note 3), the 1995 Plan was amended so that an aggregate of 10,753,000 shares of the Companys common stock was reserved for issuance. In July 2003, the Plan was further amended so that an
aggregate of 13,753,000 shares of the Companys common stock was reserved for issuance.

During 2001, $13,000 of accrued stock compensation expense was transferred to common stock upon the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



The valuation allowance for Federal and state deferred tax assets at December 31, 2003 and 2002 is
due to managements determination that, as a result of the Companys liquidity concerns, accumulated deficit and alternative strategies for the business, it is more likely than not that the deferred tax assets will not be realized in the
future.



A reconciliation of the provision for income taxes to
the amount computed by applying the statutory Federal income tax rate to income before income taxes follows:

The Company has
available Federal net operating loss carryforwards at December 31, 2003 of approximately $19,980,000, which expire from 2004 to 2023. Available state net operating loss carryforwards at December 31, 2003 total approximately $3,241,000, which expire
from 2005 to 2013. Due to the change in the Companys ownership resulting from the Redwood transaction (Note 3), the Companys utilization of both Federal and state net operating carryforwards generated prior to February 2002 is limited to
$60,000 per year. As a result of this limitation, $15,351,000 of the Companys Federal net operating loss carryforwards, and $969,000 of the Companys state net operating loss carryforwards, may expire before they can be utilized. In
addition, California placed a moratorium on the utilization of net operating loss carryforwards for 2002 and 2003. Unused investment tax and research and development and alternative minimum tax credits at December 31, 2003 aggregate approximately
$676,000 and expire from 2004 to 2013.

Preferred as determined by the if-converted method totaling 326,000 shares, 22,534,000 shares and 1,678,000 shares have been excluded from the shares used in
computing diluted net income (loss) per share for the years ended December 31, 2003, 2002 and 2001, respectively, as their effect is anti-dilutive.



On March 11, 2004, the Company declared a dividend on the Series C preferred stock totaling $158,000, for dividends accrued and payable as of January 31,
2004. Redwood, as permitted by the Certificate of Determination of the Series C preferred stock, elected to receive shares of the Companys common stock in lieu of the cash dividends. As a result, 354,000 shares of the Companys common
stock were issued to Redwoods distributees on March 11, 2004.



NOTE
13COMMITMENTS AND CONTINGENCIES:



The Company leases
office, laboratory and manufacturing facilities and equipment under operating leases. The facilities leases provide for escalating rental payments. Future minimum rentals under noncancelable operating leases as of December 31, 2003 are as follows:



|           |  |   |          
|---------- |  | - | ---------
|2004       |  | $ | 903,000  
|2005       |  |   | 923,000  
|2006       |  |   | 737,000  
|2007       |  |   | 523,000  
|2008       |  |   | 385,000  
|Thereafter |  |   | 2,022,000
|           |  |   |          
|           |  | $ | 5,493,000
|           |  |   |          



Total rent expense
under noncancelable operating leases was $1,130,000, $1,485,000 and $1,511,000 during the years ended December 31, 2003, 2002 and 2001, respectively.



On September 3, 2003, the Company filed a patent infringement lawsuit in the United States District Court for the Southern District of California against
Agen Biomedical Limited (Agen), based in Australia, claiming that Agen has infringed the Companys U.S. Patent No. 4,789,631 (the 631 Patent) pertaining to heartworm detection technology. In addition to seeking
unspecified damages, the Company has asked the Court for a declaratory judgment that Agen has willfully infringed Claim 5 of the 631 Patent. The Company has also asked the Court for an injunction against Agen, preventing Agen from importing,
selling or offering for sale their canine heartworm diagnostic test kit in the United States. On March 15, 2004, the Court issued a temporary restraining order against Agen, preventing Agens canine heartworm diagnostic product from entering
the United States market. The Court ordered that Agen, their directors, officers, employees, agents, servants, and all those in active concert or participation with them, are restrained from importing, making, using, selling, or offering for sale,
in the United States, any canine heartworm kit containing the DI 16 872.5 monoclonal antibody manufactured or supplied by Agen. The Court ruled earlier that the Company was likely to succeed on the merits of its claim that Agens canine
heartworm diagnostic product, STATScreen CHW,
which contains the Companys DI 16 872.5 monoclonal antibody, infringed the Companys United States Patent 4,789,631. A preliminary injunction hearing was held on April 15, 2004, and on April 21, 2004, the Court denied the Companys
motion and dissolved the temporary restraining order. In conjunction with the temporary restraining order, the Company was required to post a $250,000 bond; the Court has not yet released the bond. The lawsuit is currently in the discovery stage,
and a trial date is scheduled for June 28, 2004.



On September
2, 2003, Agen filed a lawsuit in the United States District Court for the Northern District of California against the Company seeking two specific forms of declaratory relief. First, Agen has asked the Court for a declaratory judgment that
Agens canine heartworm diagnostic test kit does not infringe the 631 Patent

pertaining to heartworm detection technology. Agen has also asked the Court for a declaratory judgment that Claim 5 of the 631 Patent is invalid. The
Company filed a motion with the Court to transfer the lawsuit to the United States District Court for the Southern District of California. On November 7, 2003, the Court granted the motion and the case was transferred.



NOTE 14SEGMENT INFORMATION AND SIGNIFICANT CUSTOMERS:

the fact that all of its products are animal health products. Although the Company sells diagnostic and instrument products, it does not base its business decision making on a product category basis.

Audit Committee Financial Expert



Our board of directors has determined that we do not have
an audit committee financial expert serving on our Audit Committee. The reasons that we do not have an audit committee financial expert are: we are a small company controlled by Redwood (whose representatives occupy two of our three board of
director seats); we want to save money in regards to fees paid to independent directors, especially someone qualified to serve as an audit committee financial expert; and our board of directors is satisfied that no such audit committee financial
expert is necessary to protect our shareholders given our current circumstances.



Section 16(a) Beneficial Ownership Reporting Compliance



Section 16(a) of the Securities Exchange Act of 1934 requires our officers and directors, and persons who own more than 10% of a registered class of our equity securities to file reports of ownership and changes in
ownership of our equity securities with the Securities and Exchange Commission. Officers, directors and greater than 10% shareholders are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file.



Based solely on our review of the copies of such forms furnished to us, or
written representations that no Forms 5 were required, during the fiscal year ended December 31, 2003, our officers, directors and greater than 10% beneficial owners complied with all applicable Section 16(a) filing requirements.



Code of Ethics



We have not adopted a code of ethics that applies to our principal executive officer and our principal financial officer.
Our board of directors is satisfied that no such code is necessary to protect us and our shareholders given our current circumstances, in addition to our long history of uniformly ethical conduct.

Employment Contracts and Change-in-Control
Arrangements



We entered into an employment agreement
dated December 30, 2002 with Paul R. Hays. The employment agreement, which expires December 30, 2005, provided for salary at an initial rate of $250,000 per annum, and provided for the issuance, upon Mr. Hayss relocation to San Diego, of
options to purchase 1,600,000 shares of our common stock (at $0.08 per share). Mr. Hayss current salary rate is $20,833 per month. The agreement also provides for the annual issuance, on December 30, 2003, 2004 and 2005, of options to purchase
400,000 shares of our common stock; the option price for each of the annual options will be determined by the fair market value

of our common stock on December 30 of the year in which the options are granted. Mr. Hays may receive a bonus for the years ending December 31, 2003, 2004
and 2005 calculated as follows: four percent (4.0%) of the first $1,000,000 of EBITDA in excess of $2,000,000 plus six percent (6.0%) of EBITDA in excess of $3,000,000. EBITDA is defined as earnings before; interest, income taxes, depreciation,
amortization and any settlements/awards resulting from litigation existing as of December 30, 2002. The bonus under this agreement earned by Mr. Hays in 2003 totaled $17, 628. If Mr. Hays is terminated without cause within the first 18 months of the
agreement, he will receive twelve months salary at his then base salary rate. If Mr. Hays is terminated without cause within the last 18 months of the agreement, he will receive six months salary at his then base salary rate. If Mr. Hays
is terminated without cause at any time during the agreement due to a change in control of us, he will receive twelve months salary at his then base salary rate.



We entered into an employment agreement dated May 12, 2003 with B. Kent Luther. The employment agreement, which expires
December 30, 2005, provided for salary at an initial rate of $185,000 per annum. Mr. Luthers current salary rate is $15,417 per month. If Mr. Luther is terminated without cause, he will receive six months salary at his then base
salary rate. If Mr. Luther is terminated (other than for cause) in connection with an acquisition of us, he will receive twelve months salary at his then base salary rate.



We entered into an employment agreement dated July 1, 2002 with Serge Leterme. The employment agreement provided for salary
at an initial rate of 130,000 euros per annum. Dr. Letermes current base salary rate is 10,833 euros per month (equivalent to $13,647 per month as of December 31, 2003). In addition, we have provided Mr. Leterme with a company car, for which
we are bearing the leasing costs and reasonable expenses incurred by Mr. Leterme for business activities. If Mr. Leterme is terminated without cause, he will receive the greater of six months salary at his then base salary rate or the amount
of legal severance in France.



We entered into an employment
agreement dated April 24, 2000, and amended February 14, 2001, with Robert Buchanan. The employment agreement provided for salary at an initial rate of $125,000 per annum and options to purchase 50,000 shares of our common stock (at $2.98 per
share). On April 30, 2003, Mr. Buchanan resigned as our Vice President. We entered into a separation agreement with Mr. Buchanan whereby he received severance pay and accrued vacation pay totaling $71,233.



Compensation Committee Interlocks and Insider Participation



Our Compensation Committee consists of Messrs. Donelan, Hays and Hendy. Mr.
Hays is our employee. None of our executive officers served during 2003 as a director or compensation committee member of any other company, where the other company had one of its executive officers on our board of directors or Compensation
Committee.



Report on Executive Compensation



The Compensation Committee acts on behalf of our Board of Directors to
establish our general compensation policy for all of our employees. The Compensation Committee typically reviews base salary levels on or about June 1 of each year, and reviews target bonuses for the Chief Executive Officer and other executive
officers and employees at or about the beginning of each year. The Compensation Committee administers our incentive and equity plans, including the 1995 Stock Option/Stock Issuance Plan.



The following is a report by the Compensation Committee:



General Compensation Policy



All policies, plans and actions of the Compensation Committee are formulated or taken with the goal of maximizing shareholder value by aligning the
financial interests of the President (who is our senior executive officer) and the other executive officers with those of the Companys shareholders. This is achieved through a combination of salary, short-term incentive compensation, including
cash and stock bonuses, and long-term incentive compensation, including stock options. The Compensation Committees policy is to provide the

##### Table of Contents

Companys executive officers with compensation opportunities which are based upon their personal performance, the Companys financial performance
and their contribution to that performance and which are competitive enough to attract and retain highly skilled individuals.



Each executive officers compensation package is comprises one or more of the following:



| |  |  | base salary that is competitive with the market and reflects individual performance,
| | - |  | ------------------------------------------------------------------------------------



| |  |  | short-term incentive compensation, payable in cash or stock and tied to the Companys achievement of annual performance goals, and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------



| |  |  | long term, stock-based incentive awards designed to strengthen the mutuality of interests between the Companys executive officers and its shareholders.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------



Factors



Several of the more important factors which the Compensation Committee
considered in establishing the components of each executive officers compensation package for the 2003 fiscal year are summarized below. Additional factors were also taken into account, and the Compensation Committee may in its discretion
apply entirely different factors, particularly different measures of financial performance, in setting executive compensation for future fiscal years. All compensation decisions will be designed to further the general compensation policy indicated
above.



Base Salary



In setting base salaries, the Compensation Committee considered the
following factors:



| |  |  | industry experience, knowledge and qualifications,
| | - |  | --------------------------------------------------



| |  |  | the salary levels in effect for comparable positions within the Companys principal-industry marketplace competitors,
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | historical salary levels, and
| | - |  | -----------------------------



| |  |  | internal comparability considerations.
| | - |  | --------------------------------------



The Compensation Committee did not rely upon any specific compensation surveys for comparative compensation purposes. Instead, the Compensation Committee
made its decisions as to the appropriate market level of base salary for each executive officer on the basis of its understanding of the salary levels in effect for similar positions at those companies with which the Company competes for executive
talent.



Each executive officers base salary is adjusted
yearly on the basis of the factors described above, subject to floor levels in certain officers employment agreements.



Short-Term Incentive Compensation



Annual cash and stock bonuses are awarded to the extent that the Company meets financial objectives set by the Board of Directors at the beginning of each
year. The amounts of the bonus payments, if any, are determined by the Compensation Committee, in its discretion. Mr. Hays earned a bonus for 2003 totaling $18,734. Only nominal bonuses were awarded to the other executive officers in 2003.



Long-Term Stock Based Incentive Compensation



The Compensation Committee believed that equity-based compensation in the
form of stock options can, under appropriate conditions, link the interests of management and shareholders by focusing management on increasing shareholder value. The actual value of equity-based compensation depends entirely on appreciation of the
Companys common stock.

##### Table of Contents

The Company granted no stock options during 2003, except those pursuant to the Companys employment
agreement with Paul R. Hays. The Companys employment agreement with Mr. Hays provided for the issuance, upon Mr. Hayss relocation to San Diego, of options to purchase 1,600,000 shares of the Companys common stock (at $0.08 per
share). These options were granted on April 9, 2003. The agreement also provides for the annual issuance, on December 30, 2003, 2004 and 2005, of options to purchase 400,000 shares of the Companys common stock; the option price for each of the
annual options is determined by the fair market value of the Companys common stock on December 30 of the year in which the options are granted. All of the options vest quarterly over four years from the date of grant.



Although the Compensation Committee believed the performance of the Company
and of the executive officers was satisfactory in 2003, the Compensation Committees view is that incentive compensation (above any contractual requirements) should be minimized until the Companys turnaround is further along.



Chief Executive Officer Compensation



In setting the total compensation payable to Paul R. Hays, who has served as
the Companys President since December 30, 2002, the Compensation Committee sought to be competitive with other companies in the industry. As described above under Employment Contracts, Severance Agreements and Change in Control
Agreements, an employment agreement between the Company and Mr. Hays sets forth the terms and conditions, including minimum compensation, governing Mr. Hayss employment. Mr. Hays did not receive any other cash or stock compensation
during 2003.



Compliance with Internal Revenue Code Section 162(m)



Section 162(m) of the Internal Revenue Code disallows
a tax deduction to publicly held companies for compensation paid to certain of their executive officers, to the extent that compensation exceeds $1 million per covered officer in any fiscal year. The limitation applies only to compensation that is
not considered to be performance-based. Non-performance based compensation paid to the Companys executive officers for the 2003 fiscal year did not exceed the $1 million limit per officer. The Compensation Committee does not anticipate that
the non-performance based compensation to be paid to the Companys executive officers for will exceed that limit. The Companys 1995 Stock Option/Stock Issuance Plan has been structured so that any compensation deemed paid in connection
with the exercise of option grants made under that plan with an exercise price equal to the fair market value of the option shares on the grant date will qualify as performance-based compensation which will not be subject to the $1 million
limitation. Since it is unlikely that the cash compensation payable to any of the Companys executive officers in the foreseeable future will approach the $1 million limit, the Compensation Committee has decided at this time not to take any
action to limit or restructure the elements of cash compensation payable to the Companys executive officers. The Compensation Committee will reconsider this decision if the individual cash compensation of any executive officer ever approaches
the $1 million level.



The Compensation Committee is of the
opinion that the compensation packages provided to the Companys President and the other executive officers reflect its goal of offering compensation that is fair to these officers and the Companys shareholders alike by providing adequate
base salaries together with substantial opportunity for personal financial growth which will parallel managements ability to increase shareholder value. It is intended that the total economic advantage and opportunities provided to the
executive officers will be at least equivalent to that provided by comparable corporations.
