PART I

ITEM 1  DESCRIPTION OF BUSINESS

Summary

ImmuCell Corporation was founded in 1982 and completed an initial public offering of common stock in
1987. Our purpose is to create scientifically-proven and practical products that result in a measurable economic impact on animal health and productivity in the dairy and beef industries. After achieving approval from the U.S. Department of
Agriculture (USDA) to sell First Defense® in 1991, we focused most of our efforts in the 1990s
developing human product applications of the underlying milk antibody technology. Beginning in 1999, we re-focused on First Defense® and other products for the dairy industry.

In 2000, we began the development of Mast Out®, our
Nisin-based treatment for subclinical mastitis in lactating dairy cows. No sales of this product can be made without prior approval from the Center for Veterinary Medicine, U.S. Food and Drug Administration (FDA). Because dairy producers are
required to discard milk for a period during and after treatment with all currently marketed mastitis treatment products, it is generally current practice to only treat mastitis when the disease has progressed to the stage where the milk from an
infected cow cannot be sold. Because milk from cows treated with Mast Out® may be allowed to be sold, we
believe we could revolutionize the way that mastitis is treated by removing the milk discard penalty, which would make earlier treatment of subclinically infected cows economically feasible. No other mastitis treatment product on the market has this
claim. At present, most dairy producers simply do not treat subclinically infected cows because of the milk discard or they cull the affected animals from the herd.

Many fear that the possible overuse of antibiotics in livestock could undermine the effectiveness of drugs to combat
human illnesses and may be a contributing factor to the rising problem of bacterial drug resistance. The FDA is committed to addressing its concern with respect to this important public health issue. This current environment could be favorable to
the introduction of a new product such as Mast Out®. We continue to believe that this product opportunity
justifies continued product development efforts.

During the eleven-year period that began on
January 1, 2000 and ended on December 31, 2010, we invested the aggregate of $13,965,000 in product development expenses. Approximately 54% of this amount pertained directly to the development of Mast Out®. This estimated (unaudited) allocation to Mast Out®includes no allocation of corporate overhead expenses. Approximately $2,375,000 of this investment was offset by product licensing revenues. By the end of the
second quarter of 2011, we plan to have made initial submissions to the FDA of all Technical Sections required for FDA approval of our New Animal Drug Application (NADA) with respect to Mast Out®. Additional investments, related principally to manufacturing scale-up and preparations of full-scale batches of Mast Out®, could amount to approximately $6,000,000 prior to receiving NADA approval. We have decided not to fund this
investment internally. We are engaged in negotiations with potential partners that may fund this investment as well as the marketing expenses for product launch and sales. Our objective from a successful partnership would be to benefit from the
gross margin on product that we produce and sell into distribution. We expect that a partner would benefit from a to-be-negotiated profit-sharing arrangement or a mark-up on the product sold into distribution. This strategic decision not to fund
these large, late-stage development expenses should allow us to return to positive net operating income (before other revenues (expenses), net and income taxes) during the last six months of 2011.

With our 1999 shift in focus to animal health products, we were able to record net income for each year during the
nine-year period that began on January 1, 1999 and ended on December 31, 2007. We believe that the conservative approach to financial management that is reflected in such results put us in a position to be able to weather a significant
financial downturn like the one we have been experiencing, while we have been paying for the Mast Out®product development expenses. This strategy, calling for a significant and controlled investment in the development of Mast Out®, resulted in net losses during the years ended December 31, 2008, 2009 and 2010 and is expected to result in another net loss for at least the first six
months of the year ending December 31, 2011. We believe that we have more than enough cash and short-term investments to fund our projected loss. Even without the commercial sales of Mast
Out®, we could return to profitability based principally on the sales of First Defense®. We operated without debt from 2002 until we incurred approximately $1,000,000 in mortgage debt during the third
quarter of 2010 and became further indebted under a $600,000 note payable during the first quarter of 2011. We have not had to dilute our shareholders by raising equity to fund our operations through 2010 and do not expect to do so during 2011. This
strategy has allowed us

This growth has been
accomplished with only limited dilution from the exercise of stock options. We had approximately 2,429,000 shares of common stock outstanding as of December 31, 1998 in comparison to 2,974,000 as of December 31, 2010. There were
approximately 480,000 and 273,500 shares of common stock reserved for issuance under stock options that were outstanding as of December 31, 1998 and 2010, respectively. During the twelve-year period that began January 1, 1999 and ended on
December 31, 2010, we invested the aggregate of $14,778,000 in product development expenses.

During
2006, we initiated efforts to become compliant with current Good Manufacturing Practice (cGMP) regulations in our manufacturing operations. Compliance with cGMP regulations requires a sustained investment that we believe further increases our
products quality and may open access to international markets where such standards are imposed. At the same time, we are investigating ways to develop new products utilizing our First
Defense®and Nisin technologies.

Animal Health Products for the Dairy and Beef Industries

Our lead product, First Defense®, is manufactured from cows colostrum using our proprietary vaccine and milk protein purification technologies. The target disease, bovine enteritis (calf
scours), causes diarrhea and dehydration in newborn calves and often leads to serious sickness and even death. First
Defense® is the only USDA-licensed, orally delivered scours preventive product on the market for calves with
claims against E. coli K99 and coronavirus (two leading causes of scours). We are a leader in the scours prevention market with this product. During the third quarter of 2010, we sold the 10,000,000thdose of First Defense®, since receiving USDA approval of this product in 1991. We believe that this milestone demonstrates the value of our
technology and the long-term market acceptance of our product. Harsh winter weather and severe temperature fluctuations cause stress to calves, and calves under stress are more susceptible to scours, contributing to the seasonality in the sales of
this product. Sales of this product into the beef industry are highly seasonal because most beef calves are born between January and April each year. During the second quarter of 2006, certain regional organic certifying agencies determined that the
ingredients in First Defense® are in compliance with the National Organic Program (NOP) and may be
considered for use on organic farms. First Defense® should be considered a preventive vaccine as
described in USDA-NOP regulations for organic producer consideration when establishing management plans.

First Defense® provides bovine antibodies that newborn calves need but are unable to produce on their own immediately after birth. Due to natural variability in colostrum,
newborn calves do not always get the antibodies they need from maternal colostrum. First Defense®
competes with scours vaccines, but we know that newborn calves respond poorly, if at all, to vaccines, and the immune system must be given time to develop a response to vaccines. Colostrum feeding must be delayed when calf vaccines are used, and it
is not good calf health practice to delay the feeding of colostrum while waiting for a vaccine response to be mounted. First Defense®provides immediate and preformed immunity (Immediate Immunity) when calves need it most - during the first few critical days of life. The direct, two-part
mode-of-action of First Defense® delivers specific immunoglobulins at the gut level to immediately
protect against disease, while also providing additional antibodies that are absorbed into the bloodstream. These circulating antibodies function like a natural timed-release mechanism, as they are re-secreted into the gut later to provide extended
protection. A single dose of First Defense® provides a guaranteed level of protection proven to reduce
mortality and morbidity from two major causes of calf scours. Studies have shown that calves that scour are more susceptible to other diseases and under-perform calves that do not contract scours. First Defense® is convenient. A calf needs to receive only one bolus of First Defense®within the first twelve hours after birth. The product is stored at room temperature and no mixing is required
before it is given to the calf. There is no required slaughter withdrawal period for calves that are given First
Defense®.

In 1999, we acquired Wipe Out® Dairy Wipes, which is our second leading source of product sales. That transaction included the purchase of
certain equipment, trademarks and a license of intellectual property, including several issued patents, covering the product and rights to develop skin and environmental sanitizing applications of the Nisin technology. Wipe Out® Dairy Wipes consist of biodegradable towelettes that are pre-moistened with Nisin to prepare the teat area of a
cow in advance of milking. Nisin is an antibacterial peptide that has been demonstrated in clinical studies to be an effective aid in the reduction of mastitis-causing organisms in dairy cows. Mastitis is a very common infection in dairy cows that
results in inflammation of the mammary gland. Milking regulations require that the teat area of cows be cleaned, sanitized and dried for each milking. Some dairy producers wash their cows as they approach the milking parlor. Other producers use a
variety of methods including dips and paper or cloth towels. Our wipes are made from a non-woven fabric that is strong enough to allow for a vigorous cleaning but still biodegradable for disposal. The wiping process can also help promote milk
letdown. Wipe Out® Dairy Wipes are manufactured in compliance with cGMP regulations, as required by
federal law.

In 2001, we began to offer our own, internally developed California Mastitis Test (CMT). CMT can
be used for bulk tank as well as individual cow sample monitoring and can be used to determine which quarter of the udder is mastitic. This test can be performed at cow-side for early detection of mastitis. CMT products are also made by other
manufacturers and are readily available to the dairy producer. The wholesale price of our product is generally lower than the competitive products that were present in the market when we initiated commercial sales.

In 2000, we acquired MASTiK®, Mastitis Antibiotic Susceptibility Test Kit, from an entrepreneurial veterinarian. Once mastitis is detected, there are different treatment options. MASTiK® helps veterinarians and producers quickly select the antibiotic most likely to be effective in the treatment of
individual cases of mastitis. MASTiK® can usually help make the treatment selection in less than one day,
which is faster than other commonly used antibiotic susceptibility tests. Typically, producers will treat mastitis with whatever antibiotics they have on hand while they send samples to a laboratory and wait several days for susceptibility test
results to arrive. MASTiK® allows producers to begin treatment sooner with an antibiotic that is more
likely to be effective. Sales of this product have been limited to date. Unless a bulk volume order materializes from current international or domestic customer prospects, availability of inventory for small orders in 2011 is unlikely.

In 1987, we obtained approval from the USDA to sell rjt (Rapid Johnes Test). This test can rapidly identify cattle with symptomatic Johnes Disease in a herd with 100% specificity and greater than 85%
sensitivity. Due to limited sales volume and the wider acceptance of alternative technology in the marketplace, we are not currently manufacturing or actively selling this product.

Sales and Markets

The FDA may grant a period of five
years of market exclusivity for Mast Out® (meaning the FDA might not grant approval to a second and
similar NADA for a period of five years after the first NADA approval is granted) under Section 512(c)(2)F of the Federal Food, Drug, and Cosmetic Act. Mastitis is estimated to cost U.S. dairy producers approximately $2 billion per year. These
losses include the cost of treatment products, reduced milk production, discarded milk and lost cows. We estimate that the U.S. market for the use of antibiotics to treat clinical mastitis in lactating cows is approximately $40,000,000 per year and
that similar market opportunities also exist outside of the United States and for the treatment of dry (non-lactating) cows. Because milk from cows treated with traditional antibiotics must be discarded for a period of time during and after
treatment due to concerns about antibiotic residue in the milk, currently it is not common practice to treat subclinical mastitis (those cases where cows have infected udders, but still produce saleable milk). The ability to treat such cases without
a milk discard could revolutionize the way mastitis is managed in a herd. If Mast Out® is approved by the
FDA as the first treatment for mastitis without a milk discard requirement, we believe it could open the market to treatment of subclinical mastitis and could compete effectively against the traditional antibiotic products currently on the market,
which are all sold subject to a milk discard. It is difficult to evaluate the potential size of the as-yet undeveloped subclinical mastitis treatment market.

Effective for 2011 and renewable annually by mutual agreement, we entered into a sales and marketing collaboration
with Agri Laboratories Ltd. of St. Joseph, Missouri, under which the AgriLabs sales and marketing teams are working with us to expand market demand for First Defense®. We are also investigating a product line extension of First Defense® with AgriLabs. The objective of this development is to bring our First Defense Technology, a whey

protein concentrate product, to market as a feed ingredient. The AgriLabs national marketing network consists of 20 independent distributors operating approximately 125 branch locations with more
than 700 sales representatives. AgriLabs has developed and markets more than 750 products through its own branded product lines. The AgriLabs sales team is comprised of approximately 22 well-trained, experienced professionals that cover the United
States.

The manner in which we sell and distribute our products depends, in large measure, upon the
nature of the particular product, its intended users and the country in which it is sold. The distribution channel selected is intended to address the particular characteristics of the marketplace for a given product. First Defense® is sold primarily through major veterinarian distributors. We sell Wipe Out® Dairy Wipes, MASTiK® and CMT to distributors, bovine veterinarians and directly to producers. Product selling expenses amounted to 12%, 9% and 15% of product sales in the years
ended December 31, 2008, 2009 and 2010, respectively. Our budget guideline for 2011 is to invest less than 20% of product sales in selling expenses.

First Defense® is generally sold through large, financially
strong distributors, which we believe has resulted in minimal bad debt with respect to this product. We provide for a 50% account credit for domestic distributors on expired First Defense® product, which has a two-year shelf life resulting in an immaterial amount of returns. Promotional merchandise is given to certain customers at times because we
believe it enhances brand recognition. Additionally, training meetings, incentive programs, direct mail initiatives and face-to-face solution selling are tactics we use to create brand loyalty.

International product sales represented approximately 16%, 22% and 18% of our total product sales for the years ended December 31,
2008, 2009 and 2010, respectively. The majority of these international sales were to Canada. We currently price our products in U.S. dollars. An increase in the value of the dollar in any country in which we sell products may have the effect of
increasing the local price of such products, thereby leading to a reduction in demand. Conversely, to the extent that the value of the dollar declines with respect to any other currency, our competitive position may be enhanced.

We continue our efforts to grow sales of First Defense® in North America, where there are approximately 9,000,000 cows in the United States and 1,000,000 cows in Canada. We believe that even greater market
opportunities exist in other international territories. There are estimated to be approximately 24,000,000 dairy cows in the European Union, another 9,000,000 in Russia, another 6,000,000 in Australia and New Zealand and another 800,000 in Japan.
These figures do not consider potential sales in the beef markets. Industry practices, economic conditions and cause of disease may differ in these foreign markets from what we experience in the United States. We introduced First Defense® into South Korea in 2005 and its equivalent into Japan in 2007 through collaborations with in-country
distributors.

Product Development

In 1999, we shifted the primary focus of our product development efforts from applications of our milk antibody technology for humans to scientifically-proven and practical products that result in a
measurable economic impact on animal health and productivity in the dairy and beef industries. This strategy was maintained through 2010 and is expected to continue. We spent approximately $1,746,000, $1,645,000 and $1,493,000 on product development
activities during the years ended December 31, 2008, 2009 and 2010, respectively. We expect higher product development expenses during the year ending December 31, 2011. If a partner agrees to fund the completion of the Mast Out® product development effort, these expenses would be expected to increase even higher, but only if they are off
set, in part, by the funds expected to be received from a potential strategic collaboration.

In 2000, we
acquired an exclusive license from Nutrition 21, Inc. to develop and market Nisin-based products for animal health applications, which allowed us to initiate the development of Mast Out®, our intramammary infusion product. In 2004, we paid Nutrition 21 approximately $965,000 to buy out this royalty and milestone-based license to Nisin, thereby
acquiring control of the animal health applications of Nisin. Nisin, the same active ingredient contained in Wipe
Out® Dairy Wipes, is an antibacterial peptide. Nisin is known to have activity against most gram positive
and some gram negative bacteria. Nisin is a well characterized substance, having been used in food preservation applications for over 50 years. Nisin has been granted GRAS (Generally Regarded as Safe) status by the FDA for food preservative
applications, which may be of some help in obtaining approval for the use of Mast Out® on organic farms.
Food-grade

Nisin, however, cannot be used in pharmaceutical applications because of its low purity. Our Nisin technology includes methods to achieve pharmaceutical-grade purity.

Traditional antibiotic products currently on the market for use in the treatment of mastitis are sold subject to a
regulatory requirement to discard milk from treated cows during the course of and for a period following antibiotic treatment (the milk discard requirement). Currently, mastitis treatment is generally limited to only clinical cases - those cases
where cows are producing abnormal milk - since that milk already is unsuitable for commercial sale. Because milk from cows infected with subclinical mastitis (those with infected udders, but still producing normal milk) can be sold, dairy producers
generally do not treat subclinical mastitis. Doing so would give rise to the milk discard requirement and a resulting loss in revenue to the dairy producer. The safety profile of Nisin may allow for the use of Mast Out® in the U.S. without a milk discard requirement, which would be a significant competitive advantage. We are not
aware of any other intramammary mastitis treatment product that has such a zero discard claim. Without the milk discard requirement, we believe Mast Out® could expand the subclinical mastitis treatment market niche. While the benefit of treating clinical mastitis is widely known, there is a growing awareness of the
cascade of events associated with subclinical mastitis, including reduced or foregone milk quality premiums, increased abortions, lower milk production and increased cull rates. Some industry experts have estimated that subclinical mastitis costs
the U.S. dairy industry approximately $1 billion per year. Regulations in the European Union will likely require that Mast
Out® be sold subject to a milk discard requirement in that territory, although the duration of the milk
discard requirement may be shorter than the discard requirement applicable to competitive products on the market.

In 2004, we entered into a product development and marketing agreement with Pfizer Animal Health, a division of Pfizer, Inc., covering Mast Out®. Under that agreement (as amended and supplemented and later terminated), we received $2,375,000 in payments from Pfizer. Pfizer elected to terminate the product
development and marketing agreement in 2007. Soon thereafter, Pfizer returned to us all rights, data, information, files, regulatory filings, materials and stocks of Nisin and Nisin producing cultures relating to the development of Mast Out®. We believe that Pfizers decision to terminate the product development and marketing agreement was not
based on any unanticipated efficacy or regulatory issues. Rather, we believe Pfizers decision was primarily market driven, largely relating to concerns that the use of Mast Out® may require specific treatment restrictions at the herd level.

A significant risk to the market success of Mast Out® is
that the use of Mast Out® may require specific treatment restrictions at the herd level when used to
treat subclinical mastitis with no milk discard. Due to its antibacterial nature, Nisin in bulk tank milk could interfere with the manufacture of certain (but not all) cultured milk products, such as some kinds of cheese and yogurt, if a high enough
percentage of animals from a herd is treated at any one time. We are evaluating potential strategies to quantify and manage this risk. Milk that is sold exclusively for fluid milk products would not be subject to this restriction. We believe that
the benefits of using Mast Out® would outweigh the management costs associated with implementing a
potential treatment restriction. Another risk is that Mast Out® likely will be priced at a premium to the
traditional antibiotic products currently on the market, that are all sold subject to a milk discard requirement.

In 2007, we began the production of registration batches of drug product at 10% of commercial scale to fulfill the pivotal regulatory requirements of effectiveness, target animal safety and stability.
During the second quarter of 2008, we initiated the pivotal effectiveness study. Positive results from the study were announced during the third quarter of 2009. With enrollment of approximately 300 qualified cows with subclinical mastitis, the
Mast Out®treatment group showed a statistically highly significant (p<0.0001) overall cure rate in
comparison to the placebo group. We believe that the breakdown of the data by species suggests both the necessary numerical superiority and clinical relevancy to support robust product performance in the field. For example, one of the most important
mastitis pathogens, coagulase-negative staphylococci, predominated in our study, and Mast Out®achieved
almost 10-fold higher cure rates than the placebo-treated animals against this pathogen. Further, Mast Out®treatment was associated with a statistically significant (p<0.005) reduction in milk somatic cell count (SCC), which is an important measure of milk quality.

Commercial introduction of Mast Out® in the United States is subject to approval of our NADA by the FDA, which approval cannot be assured. Foreign regulatory approvals would be required for sales in
key markets outside of the United States and would involve some similar and some different requirements. The NADA is comprised of five principal Technical Sections subject to the FDAs phased review of a NADA. By statute, each Technical Section

ImmuCell Corporation



submission is subject to a six-month review cycle by the FDA. The current status of our work on these Technical Sections is as follows:

1) Environmental Impact: During the third quarter of 2008, we received the Environmental Impact Technical Section Complete Letter from
the FDA.

2) Effectiveness: During the third quarter of 2010, we made our first submission of the
Effectiveness Technical Section. This 65 volume submission contains the results from our pivotal trial conducted from 2008 to 2009 as well as all supporting data related to the effectiveness of Nisin, demonstrating the effectiveness of Mast Out®in the field at a level similar to currently marketed intramammary antibiotics and confirming prior results from
two major field studies conducted since 2003. During the first quarter of 2011, we received an Effectiveness Technical Section Incomplete Letter from the FDA. The FDA has requested additional information in the areas of raw data, subject eligibility
and statistical analyses and has requested that certain treatment outcomes be changed or justified. Additional clinical studies are not required. Our response to the FDA is not expected to materially change our initial conclusions about the
products effectiveness. We expect to make a second submission of this Technical Section that will be responsive to the questions raised by the FDA during the second quarter of 2011. We would expect the FDAs response to this second
submission during the fourth quarter of 2011 after one, six-month review cycle.

3) Human Food Safety (HFS): The HFS Technical
Section submission was made during the fourth quarter of 2010. This Technical Section determines if a milk discard period or meat withhold period will be required. This Technical Section includes several subsections such as: a) toxicology, b) total
metabolism, c) effects of drug residues in food on human intestinal microbiology, d) effects on bacteria of human health concern (antimicrobial resistance) and e) pivotal residue chemistry. A zero meat withhold requirement, during the course of and
for any period following treatment, has been granted. The Acceptable Daily Intake (ADI) level for humans consuming milk from treated cows has been accepted by the FDA, and this ADI supports a zero milk discard claim. We expect the FDAs
response to this submission during the second quarter of 2011 after one, six-month review cycle.

4) Target Animal Safety:
Under a protocol approved in advance by the FDA, the pivotal Target Animal Safety trial was completed during the first quarter of 2010. We expect to submit the Target Animal Safety Technical Section to the FDA for review during the second quarter of
2011. We would expect the FDAs response to this submission during the fourth quarter of 2011 after one, six-month review cycle.

5) Chemistry, Manufacturing and Controls (CMC): We have entered into agreements with three manufacturers to produce inventory for us utilizing our proprietary technology and processes. We have entered
into a long-term, exclusive supply agreement with Plas-Pak Inc. of Norwich, Connecticut covering the proprietary syringe that was developed specifically for Mast Out®. These syringes were used for all pivotal studies of Mast Out®. During the third quarter of 2010, we entered into a Development and Manufacturing Agreement with Lonza Sales, Ltd. of Basel, Switzerland covering the exclusive
manufacture of the Active Pharmaceutical Ingredient (API) by Lonza for Mast Out®. The identified
manufacturing site in Europe is FDA-approved, compliant with current Good Manufacturing Practices (cGMP) regulations and subject to future FDA approval and inspection. During the third quarter of 2010, we entered into an exclusive Contract
Manufacture Agreement with Norbrook Laboratories Limited of Newry, Northern Ireland, an FDA-approved drug product manufacturer, to formulate the API into drug product, conduct sterile-fill of syringes and perform final packaging. Norbrook provided
these services for clinical material used in all pivotal studies of Mast Out®. Our successful operation
under these collaborative agreements with these highly qualified partners is crucial to our success. We expect to make our first submission of the CMC Technical Section to the FDA for review during the second quarter of 2011. We would expect the
FDAs response to this submission during the fourth quarter of 2011 after its first, six-month review cycle. We expect that a second CMC Technical Section submission will be required because production facility modifications and full-scale
manufacturing batches (which will not be completed for the first submission) will be required for approval of this Technical Section. The completion of this work and compilation of the relevant data is subject to the strategic funding collaboration
discussed above. The timing of the second submission of the CMC Technical Section and the following six-month FDA review cycle defines the critical path to the submission of the administrative NADA to the FDA.

6) Several Administrative Requirements: After obtaining the last Technical Section Complete Letter, preparing materials responsive to
other administrative requirements and assembling the administrative NADA submission for final review by the FDA - a statutory sixty-day review period of the administrative NADA would be expected. The timing of



6

##### Table of Contents

ImmuCell Corporation



the administrative NADA submission and the timing of a potential market launch (if the FDA grants approval) will be determined by the FDAs responses to our outstanding Technical Section
submissions and by the successful resolution of any identified issues. Product produced for the validation batches under the CMC Technical Section could be sold in test markets upon FDA approval.

In addition to our work on Mast Out®, we are actively exploring further improvements, extensions or additions to our current product line. For example, we currently are investigating therapies that
could prevent scours in calves caused by enteric pathogens other than E. coli K99 and bovine coronavirus (the current First Defense® claims). In connection with that effort, during the second quarter of 2009 we entered into an exclusive license with Baylor College of Medicine covering certain
rotavirus vaccine technology. This perpetual license (if not terminated for cause) is subject to milestone and royalty payments. Results from pilot studies completed during the first quarter of 2009 justify continued product development. It is our
objective to initiate a pivotal effectiveness study during the second quarter of 2011. Successful results could position us for USDA approval in 2011 of an additional disease claim for First
Defense® to prevent scours caused by rotavirus. As additional opportunities arise to commercialize our own
technology, or licensable technology, we may begin new development projects. While we continue to pursue internally funded product development programs, we also remain interested in acquiring new products and technologies that fit with our sales
focus on the dairy and beef industries.

Competition

Our competition in the animal health market includes other biotechnology companies and major animal health companies. Many of these competitors have substantially greater financial, marketing,
manufacturing and human resources and more extensive product development capabilities than we do. Many may be capable of developing technologies and/or products that are superior to ours, or may be more successful in developing production capability
or in obtaining required regulatory approvals.

We believe that First Defense® offers two significant competitive advantages over other oral antibody products on the market. First, its
capsule form does not require refrigeration and provides ease of administration. Second, First Defense®
provides protection against the leading cause of calf scours (E. coli) and additional protection against coronavirus, another leading cause of the disease. In addition to direct competition from oral antibody products, First Defense® also competes for market share against vaccine products that are used to increase the production of antibodies
by the dam that can then be transferred through the mothers milk to the calf and against vaccine products that are administered to the newborn calf. The immediate and preformed immunity (Immediate Immunity) that First Defense® provides to the calf is a competitive advantage over the vaccine products. Certain licensed products that
compete directly with First Defense® have been experiencing back log issues. First Defense®also competes against scours preventives that are not licensed by the USDA.

There are many products on the market that may be used in place of Wipe Out® Dairy Wipes. Wipe Out® Dairy Wipes sell at a premium to most of them. These products include teat dips, teat sprays and other disposable and washable towel products offered by several
different companies. Competitive advantages of Wipe Out® Dairy Wipesinclude that they are convenient to
use, they do not irritate the udder, they do not adulterate the milk and they are biodegradable.

We would
consider any company that sells an antibiotic to treat mastitis, such as Pfizer Animal Health, Merck/Intervet/Schering Plough Animal Health and Boeringher Ingelheim, to be among the potential competitors for Mast Out®.

We may not be aware of competition that we face from other companies. Our competitive position will be highly influenced by our ability to attract and retain key scientific and managerial personnel, to
develop proprietary technologies and products, to obtain USDA or FDA approval for new products, to effectively promote and market our products and to continue to profitably sell our current products. We currently compete on the basis of product
performance, price and distribution capability. We continue to monitor our network of independent distributors to maintain our competitive position.

Patents, Proprietary Information and Trademarks

In connection with the December 1999 acquisition of Wipe Out® Dairy Wipesand the April 2000 license to all veterinary applications of Nisin from Nutrition 21, Inc., we acquired a license to six patents. In November 2004, we
bought out certain future milestone and royalty obligations under the 1999 and 2000 licenses, which principally resulted in a fully paid, perpetual license related to the animal health applications of Nisin. Four of these six patents have expired or
are expiring and one of the two longer-term patents may be subject to a patent term extension. In 2004, we were issued U.S. Patent No. 6,794,181 entitled Method of Purifying Lantibiotics covering a key step in a manufacturing
process for pharmaceutical-grade Nisin. We are investigating the merits of filing a new patent application directed toward what we believe to be a novel step in our manufacturing process.

In 2000, we were issued U.S. Patent No. 6,074,689 entitled Colonic Delivery of Protein or Peptide Compositions covering
the method of formulation that can be used to deliver proteins to the colon. In 1999, we acquired an exclusive license for pharmaceutical applications to U.S. Patent No. 5,773,000 entitled Therapeutic Treatment of Clostridium
difficile Associated Diseases from GalaGen, Inc. In 2002, we acquired ownership of this patent from the court administering the bankruptcy proceedings of GalaGen. These patents are included in the license we granted to Immuron, Ltd.
(formerly known as Anadis) of Australia in 2008.

In the future, we may file additional patent applications for certain
products under development. There can be no assurance that patents will be issued with respect to any pending or future applications.

In some cases, we have chosen (and may choose in the future) not to seek patent protection for certain products or processes. Instead, we have sought (and may seek in the future) to maintain the
confidentiality of any relevant proprietary technology through operational measures and contractual agreements. Reliance upon trade secret, rather than patent, protection may cause us to be vulnerable to competitors who successfully replicate our
manufacturing techniques and processes. Additionally, there can be no assurance that others may not independently develop similar trade secrets or technology or obtain access to our unpatented trade secrets or proprietary technology. Other companies
may have filed patent applications and may have been issued patents involving products or technologies potentially useful to us or necessary for us to commercialize our products or achieve our business goals. There can be no assurance that we will
be able to obtain licenses to such patents on terms that are acceptable.

We have registered certain
trademarks with the U.S. Patent and Trademark Office in connection with the sale of our products. We own federal trademark registrations of the following trademarks: ImmuCell, First Defense®, our calf scours preventive product; Wipe Out® Dairy Wipes and the related design and the trademark One Step Cow Prep®, our pre-milking wipe product;
MASTiK®, our antibiotic susceptibility test; and Mast Out®.

Government Regulation

We believe that we are in compliance with current regulatory requirements relating to our business and products. The manufacture and sale of animal health biologicals within the United States is generally
regulated by the USDA. We have received USDA and Canadian Food Inspection Agency approval for First Defense®(our scours preventive product). Mast Out® is regulated by the FDA, Center for Veterinary Medicine,
which regulates veterinary drugs. The manufacture of Wipe Out® Dairy Wipes also is regulated by the FDA,
Center for Veterinary Medicine. Comparable agencies exist in foreign countries and foreign sales of our products will be subject to regulation by such agencies. Many states have laws regulating the production, sale, distribution or use of biological
products, and we may have to obtain approvals from regulatory authorities in states in which we propose to sell our products. Depending upon the product and its applications, obtaining regulatory approvals may be a relatively brief and inexpensive
procedure or it may involve extensive clinical tests, incurring significant expenses and an approval process of several years duration.

investments in facility modifications and production equipment or the availability and cost of alternative manufacturing and/or distribution resources; the future adequacy of our working capital
and the availability of third party financing; future expense ratios; costs and timing associated with sustaining compliance with cGMP regulations; anticipated competitive and market conditions; and any other statements that are not historical
facts. Forward-looking statements can be identified by the use of words such as expects, may, anticipates, intends, would, could, should, will,
plans, believes, estimates, targets and similar words and expressions. In addition, there can be no assurance that future developments affecting us will be those that we anticipate, especially
considering the effects the distress in credit and capital markets will have on our current and prospective customers and the global economy and the uncertainties surrounding the potential for a prolonged global recession. Such statements involve
risks and uncertainties, including, but not limited to, those risks and uncertainties relating to difficulties or delays in development, testing, regulatory approval, production and marketing of our products, competition within our anticipated
product markets, the uncertainties associated with product development, manufacturing reliance upon third parties for products and services, changes in laws and regulations, decision making by regulatory authorities, currency fluctuations and other
risks detailed from time to time in filings we make with the Securities and Exchange Commission, including our Quarterly Reports on Form 10-Q, our Annual Reports on Form 10-K and our Current Reports on Form 8-K. Such statements are based on our
current expectations, but actual results may differ materially due to various factors, including the risk factors summarized below and uncertainties otherwise referred to in this Annual Report.

Risks associated withMast Out®funding strategy: There are risks associated with our decision not to internally fund the development of Mast Out® through to the submission of the administrative NADA to the FDA. A development and marketing partner may not be
willing to step in and fund the completion of this product development effort. If a partner does help us complete the submission, the FDA may never grant approval of this product. If a partner is not willing to come to acceptable terms on this
collaboration with us, we will need to re-evaluate alternative strategies that do not involve risking significantly more of our capital in order to get full NADA approval and to support the product launch. After we have made submissions of all
required Technical Sections to the FDA, this product development effort would essentially be put on hold pending a funding agreement with a partner or implementation of an alternative strategy, while we would turn our focus to our commercial
business.

Projections of loss before income taxes and net loss: After nine consecutive years of
reporting net income, we reported a loss before income taxes of $961,000 and a net loss of $469,000 for the year ended December 31, 2008, a loss before income taxes of $429,000 and a net loss of $216,000 for the year ended December 31,
2009 and a loss before income taxes of $683,000 and a net loss of $385,000 for the year ended December 31, 2010 due in large part to our current product development strategy. Continued development of Mast Out® will likely result in a net loss for the six-month period ending June 30, 2011. Our decision not to fund
the majority of the remaining expenses to complete the development of Mast Out® may allow us to return to
positive net operating income (before other revenues (expenses), net and income taxes) during the last six months of 2011. Generally speaking, our financial performance can differ significantly from management projections, due to numerous factors
that are difficult to predict or that are beyond our control. Stronger than expected sales of First
Defense®, for example, could diminish the overall loss. Conversely, weaker than expected sales of First
Defense® could lead to larger losses. Prior to 2008, we had not publicly disclosed our projections of future
profitability. We did so in 2008, 2009 and 2010 and have done so again for 2011 to make it clear to our stockholders that the decision to pursue internal development of Mast Out® entails an important change in our financial model and strategy that, we believe, is in the long-term interests of the Company and its stockholders.

Exposure to risks associated with the financial downturn and global economic crisis: The U.S. economy appears to be just coming
out of a recession, caused principally by the housing, credit and financial crises. The credit markets continue to be very turbulent and uncertain. Sales and financial performance are still down at many businesses. This extraordinary period of
instability facing the U.S. economy and the financial markets has been troubling for nearly all Americans. The national unemployment rate is too high, the housing market remains problematic for the overall U.S. economy and the U.S. has taken on too
much national debt. A continued and prolonged economic downturn could have a corresponding negative effect on our business and operations.

Economics of the dairy industry: The U.S. dairy industry has been facing very difficult economic pressures, which are forcing many dairy producers out of business. The size (annual average) of the
U.S. dairy herd ranged from approximately 9,011,000 to 9,199,000 cows from 1998 to 2007. This annual average jumped to 9,315,000 cows in 2008. The annual average was 9,200,000 in 2009 and 9,112,000 in 2010 The size of the milking herd affects the
price of milk. The impact on the milk supply from this decrease in cows is offset, in part, by an increase in milk production per cow.

Sales of our products may be influenced by the prices of milk, milking cows and calves. The Class III milk price is an industry benchmark that reflects the value of product used to make cheese.
The Class III milk price (which is largely out of the direct control of individual dairy producers) is an important indicator because it defines our customers revenue level. The average Class III milk price for 2008 was $17.44 per 100 pounds,
which represented a 3% decrease from the 2007 average of $18.04. For 2009, this price level averaged $11.36, which represents a 35% decrease from 2008. The average price for 2009 was 36% lower than the average experienced during the two-year period
ended December 31, 2008. For 2010, this price level averaged $14.41, which represents a 27% increase from 2009 but is well below the 2007 and 2008 levels. While the number of cows in the U.S. herd and the production of milk per cow directly
influence the supply of milk to the market, demand for milk has been largely influenced by very volatile international demand for milk products. However, the actual level of milk prices may be less important than their level relative to costs. One
measure of this relationship is known as the milk-feed price ratio, which represents the amount of feed that one pound of milk can buy. Whenever this ratio meets or exceeds 3.0, it is considered profitable to buy feed and produce milk. For 2008,
this ratio averaged 2.01. For 2009, this ratio averaged 1.78, representing a 12% decrease compared to 2008. For 2010, this ratio averaged 2.27, representing a 27% increase compared to 2009. This means that a dairy producer can buy only 2.27 pounds
of feed for every pound of milk sold. Recent improvement in milk prices has been offset by higher feed costs. An increase in feed costs also has a negative impact on the beef industry. Another indication of the economic condition of the dairy
industry is the average price for animals sold for dairy herd replacement. In 2008, this average price (reported as of January, April, July and October) is estimated to have increased to approximately $1,953, which was a 6% increase over 2007. This
price averaged approximately $1,385 in 2009, which represented a 29% decrease in comparison to the same period in 2008. This price averaged approximately $1,330 in 2010, which represented a 4% decrease in comparison to the same period in 2009. The
dairy industry data referred to above is compiled from USDA databases. Another factor in the demand for our product is the value of bull calves. A decline in the price of bull calves reduces the return on investment from a dose of First Defense®for bull calves. We are trying to maintain and grow our sales for use with heifer calves to offset what we
assume is a significant decrease in the use of our product for bull calves. Given our focus on the dairy and beef industries, the financial insecurity of our primary customer base is a risk to our ability to maintain and grow sales at a profitable
level. Further, the loss of farms from which we buy raw material for First Defense®could make it
difficult for us to produce enough inventory until supply agreements are reached with replacement farms on suitable terms.

Product risks generally: The sale of our products is subject to financial, efficacy, regulatory and competitive and other market
risks. We cannot be sure that we will be able to maintain the regulatory compliance required to continue selling our products. There is no assurance that we will continue to achieve market acceptance at a profitable price level or that we can
continue to manufacture our products at a sufficient gross margin.

Product Liability:The manufacture and sale of
certain of our products entails a risk of product liability. Our exposure to product liability is mitigated to some extent by the fact that our products are principally directed towards the animal health market. We have maintained product liability
insurance in an amount which we believe is reasonable in relation to our potential exposure in this area.

Reliance on sales ofFirst Defense®:We
are heavily reliant on the market acceptance of First Defense® to generate product sales and fund our
operations. Our business would not have been profitable during the nine consecutive years in the period ended December 31, 2007, and our net losses would have been larger during the years ended December 31, 2008, 2009 and 2010, without the
gross margin that we earned from the sale of First Defense®.

Concentration of sales: A large portion of our product sales (47%, 49% and 49% for the years ended December 31, 2008, 2009
and 2010, respectively) was made to three large distributors. A large portion of our trade accounts receivable (62% as of December 31, 2009 and 47% as of December 31, 2010) was due from these three distributors. We have a good history with
these distributors, but the concentration of sales and accounts receivable with a small number of customers does present a risk to us.

Product development risks: Our current strategy relies heavily on the development of new products, the most important of which is Mast Out®. The development of new products is subject to financial, scientific, regulatory and market risks. In particular, the development of Mast Out® requires (and will continue to require) substantial investments by us and by a potential partner, and there is
no assurance that we will obtain all of the clinical and other data necessary to support regulatory approval for this product. The market for the treatment of mastitis in dairy cows is

##### Table of Contents

ImmuCell Corporation



highly competitive, and presently is dominated by large companies such as Pfizer, Merck/Intervet/Schering Plough and Boehringer Ingelheim. There is no assurance that Mast Out® will compete successfully in this market.

Regulatory requirements forMast Out®: The commercial introduction of Mast Out®in the United States will require us to obtain appropriate FDA approval for this product. Approval of a zero milk discard claim is a critical competitive feature
of this product. It presently is uncertain whether or when this approval will be achieved. We are exposed to additional regulatory compliance risk through the subcontractors that we choose to work with to produce Mast Out®. Foreign regulatory approvals would be required for sales outside of the United States. European regulatory
authorities are not expected to approve a product with a zero milk discard claim, which would remove a significant competitive advantage of Mast Out® in that territory.

Risks associated with USDA regulatory oversight: First Defense®, and modifications and extensions thereto, is subject to the jurisdiction of the Center for Veterinary
Biologics, USDA. Recent budgetary constraints at the USDA have caused significant delays in rulings and responses to submissions, according to the Association of Veterinary Biologics Companies, of which we are a member. Similar regulatory oversight
risks exist in territories outside of the United States where we sell our products.

Regulatory
requirements forFirst Defense®: First Defense® is sold in the United States subject to a product license approval from the USDA, first obtained in 1991. The
potency of serial lots is directly traceable to the original serial used to obtain the product performance claims (the Reference Standard). Due to the unique nature of the First
Defense® label claims, host animal re-testing is not required as long as periodic laboratory analyses
continue to support the stability of stored Reference Standard. To date, these analyses have demonstrated strong stability. However, if the USDA were not to approve requalification of the Reference Standard, additional clinical studies could be
required to meet regulatory requirements and allow for continued sales of the product. During 2006, certain regional organic certifying agencies determined that the ingredients in First Defense® are in compliance with the National Organic Program (NOP) and may be considered for use on organic farms. First Defense® should be considered a preventative vaccine as described in USDA-NOP regulations for organic producer
consideration when establishing management plans.

Regulatory requirements forWipe Out® Dairy Wipes: While the FDA regulates the manufacture and sale of Wipe Out®, this type of product is permitted to be sold without a NADA approval, in accordance with the FDAs
Compliance Policy Guide 7125.30 (Teat Dips and Udder Washes for Dairy Cows and Goats). This policy guide could be withdrawn at the FDAs discretion, in which case we would likely discontinue sales of the product. The manufacture of
Wipe Out® is subject to Part 211 of the cGMP regulations. As such, our operations are subject to
inspection by the FDA. We continue to invest in personnel, facility improvements and new equipment to sustain compliance with cGMP regulations across our entire product line. In June 2007, we received a Warning Letter from the FDA citing
deficiencies in specific areas of the cGMP regulations. We filed a response to the FDA in June 2007, and we responded to a request for additional information in April 2008. We believe we have substantially corrected the deficiencies cited, but have
received no further communications from the FDA on this subject. We remain subject to the risk of adverse action by the FDA in this respect.

Uncertainty of market estimates: Even assuming that Mast
Out® achieves regulatory approval in the United States with a zero milk discard requirement, estimating the
size of the market for this product is subject to numerous uncertainties. Some of the uncertainties surrounding our product include the development of the subclinical mastitis treatment market, coverage of relevant pathogens, selling price and its
effect on market penetration, cost of manufacture, integration of milk from treated cows into cheese starter cultures and market acceptance.

Competition from others: Many of our competitors are significantly larger and more diversified in the relevant markets, and have substantially greater financial, marketing, manufacturing and human
resources and more extensive product development capabilities than do we, including greater ability to withstand adverse economic or market conditions and declining revenues and/or profitability. We may not be aware of other companies that compete
with us or intend to compete with us in the future. Our competitive position will be highly influenced by our ability to attract and retain key scientific and managerial personnel, to develop proprietary technologies and products, to obtain USDA or
FDA approval for new products and to continue to profitably sell our current products. We currently compete on the basis of product performance, price and distribution capability. We continue to monitor our network of independent distributors to
maintain our competitive position.

Failure to protect intellectual property: In some cases, we have chosen (and may
choose in the future) not to seek patent protection for certain products or processes. Instead, we have sought (and may seek in the future) to maintain the confidentiality of any relevant proprietary technology through operational safeguards and
contractual agreements. Reliance upon trade secret, rather than patent, protection may cause us to be vulnerable to competitors who successfully replicate our manufacturing techniques and processes. Additionally, there can be no assurance that
others may not independently develop similar trade secrets or technology or obtain access to our unpatented trade secrets or proprietary technology. Other companies may have filed patent applications and may have been issued patents involving
products or technologies potentially useful to us or necessary for us to commercialize our products or achieve our business goals. There can be no assurance that we will be able to obtain licenses to such patents on terms that are acceptable. There
is a risk that competitors could challenge the claims in patents that have been issued to us.

Small size: We are a
small company with 29 full-time and 3 part-time employees. As such, we rely on certain key employees to support different operational functions, with limited redundancy in capacity. The loss of any of these key employees could adversely affect our
operations until a qualified replacement is hired and trained.

Our reporting obligations as a public company are
costly: Operating a public company involves substantial costs to comply with reporting obligations under federal securities laws and the provisions of the Sarbanes-Oxley Act of 2002.

Access to raw materials: Our policy is to maintain more than one source of supply for the components used to
manufacture and test our products. However, there is a risk that we could have difficulty in efficiently acquiring essential supplies. We are dependent on our manufacturing operations and facility at 56 Evergreen Drive in Portland, Maine for the
production of First Defense® and Wipe Out® Dairy Wipes. The specific antibodies that we purify for First Defense® and the Nisin we produce by fermentation for Wipe Out® Dairy Wipesare not readily available from other sources. We expect to be dependent on Plas-Pak, Lonza and Norbrook for the manufacture of Mast Out® if that product proceeds to commercialization. Any significant damage to or other disruption in the services at
these facilities could adversely affect the production of inventory and result in significant added expenses and loss of sales.

Bovine diseases: The potential for epidemics of bovine diseases such as Foot and Mouth Disease, Bovine Tuberculosis, Brucellosis and Bovine Spongiform Encephalopathy (BSE) presents a risk to us and
our customers. Documented cases of BSE in the U.S. have led to an overall tightening of regulations pertaining to ingredients of animal origin, especially bovine. First Defense® is considered a veterinary medicine rather than a feed ingredient, and it is manufactured from bovine milk and colostrum, which is not considered a BSE risk
material. Future regulatory action to increase protection of the human food supply could affect First
Defense®, although presently we do not anticipate that this will be the case.

Biological terrorism: The threat of biological terrorism is a risk to both the economic health of our customers and to our ability
to economically acquire and collect good quality raw material from our contract farms. Any act of widespread bioterrorism against the dairy industry could adversely affect our operations.

No expectation to pay any dividends for the foreseeable future:We do not anticipate paying any dividends to our stockholders for
the foreseeable future, instead using cash to fund product development costs. Also, any debt or equity financing we obtain to assist in funding our product development programs may include terms prohibiting or restricting our paying dividends or
repurchasing stock for a lengthy period. Stockholders must be prepared to rely on sales of their common stock after price appreciation to earn an investment return, which may never occur. Any determination to pay dividends in the future will be
made at the discretion of our Board of Directors and will depend on our results of operations, financial condition, contractual restrictions, restrictions imposed by applicable laws and other factors our Board of Directors deems relevant.

Market for common stock: Our common stock trades on the Nasdaq Stock Market (NASDAQ: ICCC). Our average daily trading
volume is lower than the volume for most other companies, which could result in investors facing difficulty selling their stock for proceeds that they may expect or desire.

ITEM 2  DESCRIPTION OF PROPERTY

We own a 27,750 square foot building at 56 Evergreen Drive in Portland, Maine. We currently use this space for substantially all of our
office, laboratory and manufacturing needs. When we originally purchased this building in 1993, its size was 15,000 square feet, including 5,000 square feet of unfinished space on the second floor. In May 2001, we completed a construction project
that added approximately 5,200 square feet of new manufacturing space on the ground level. The 2001 facility addition also added a storage mezzanine of approximately 4,100 square feet on the second floor. In May 2007, we completed a renovation
project converting the 5,000 square feet of unfinished space on the second floor into usable office space. After moving first floor offices into this space, we modified and expanded the laboratory space on the first floor. As part of the 2007
project, we also added approximately 2,500 square feet of mezzanine storage space in the second floor. During 2009, we added 600 square feet to the mezzanine storage area and 350 square feet of cold storage space. We funded these investments with
available cash. These investments are an integral part of our strategy to increase our production capacity and to be compliant with cGMP regulations in our manufacturing operations.

We rent approximately 550 square feet of office and warehouse space in New York State on a short-term basis to support our farm
operations.

We maintain property insurance in amounts that approximate replacement cost and a modest amount of business
interruption insurance. We also maintain access to certain animals, primarily cows, through contractual relationships with commercial dairy farms.

ITEM 7  MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Results of Operations

Fiscal Year
2010 Compared to Fiscal Year 2009

Product Sales

Product sales for the year ended December 31, 2010 decreased by 3%, or $120,000, to $4,386,000 from $4,506,000 in 2009. Domestic
product sales increased by 2%, or $76,000, during the year ended December 31, 2010, while international sales decreased by 20%, or $196,000, in comparison to 2009. For the three-month period ended December 31, 2010, product sales increased
by 9%, or $89,000, in comparison to the three-month period ended December 31, 2009. We expect some sales volatility in our international sales. We believe that sales of our products were influenced by the price of milk, cows and calves and by
the cost of feed.

Sales of First Defense® decreased by 2% during the year ended December 31, 2010 in comparison to 2009. Domestic sales of First Defense®increased by 2%, but international sales decreased by 18%. Sales of First Defense® increased by 13% during the three-month period ended December 31, 2010 in comparison to the three-month
period ended December 31, 2009. Sales of First Defense® are normally seasonal, with higher sales
expected during the first quarter. First Defense®continued to benefit in 2010 from wide acceptance by
dairy and beef producers as an effective tool to prevent bovine enteritis (calf scours).

Sales of Wipe
Out® Dairy Wipesincreased by 10% during the year ended December 31, 2010 in comparison to 2009. We
believe that sales growth potential for Wipe Out® Dairy Wipes is limited because most of our sales of
this product tend to be to smaller dairies that are under continued financial pressures that are forcing many small dairy producers out of business and because, while our product is a high quality tool, there are less expensive ways to sanitize a
cow prior to milking.

The other products we sell primarily into the dairy industry
decreased to 3% of product sales during the year ended December 31, 2010 compared to 4% of product sales during 2009. The other products we sell outside of the dairy and beef industries, principally Isolate (formerly known as
Crypto-Scan®), aggregated 3% of product sales during the years ended December 31, 2010 and 2009.

We generally held our product selling prices without increase during the seven year period ended
December 31, 2007. During the first quarter of 2008, we implemented a modest increase to the selling price of First
Defense®. We have implemented no significant price increases since then.

Gross Margin

Changes in the gross margin on product sales are summarized in the following table for the respective periods (in thousands, except for percentages):



|                         |  |                         |       |   |          |   |       |        |  |   |    |   |  |  |   |  
|------------------------ |  | ----------------------- | ----- | - | -------- | - | ----- | ------ |  | - | -- | - |  |  | - | -
|                         |  | Years EndedDecember 31, |       |   | Decrease |  
|                         |  | 2010                    |       |   | 2009     |   |       | Amount |  |   | %  |  
|Gross margin             |  | $                       | 2,302 |   |          | $ | 2,398 |        |  | $ | 96 |   |  |  | 4 | %
|Percent of product sales |  |                         | 52    | % |          |   | 53    | %      |  |   | 1  | % |  |  | 2 | %

The
gross margin as a percentage of product sales was 52% and 53% during the years ended December 31, 2010 and 2009, respectively. This compares to gross margin percentages of 45% and 52% for the years ended December 31, 2008 and 2007,
respectively. We experienced an unusually low gross margin percentage during 2008 in comparison to those achieved in other periods. Our current annual target is to maintain the gross margin percentage at approximately 50%. A number of factors
account for the variability in our costs. We expect some fluctuations in gross margin percentages from quarter to quarter. The gross margin on First Defense® is affected by biological yields from our raw material, which do fluctuate over time. More generally, costs for production of First Defense®and Wipe Out® Dairy Wipeshave increased due to increased labor costs and expenses associated with our efforts to sustain compliance with cGMP regulations in our production
processes. Like most manufacturers in the U.S., we have been experiencing increases in the cost of raw materials that we purchase. We have been able to minimize the impact of these cost increases by implementing yield improvements. Product mix also
affects gross margin in that we earn a higher gross margin on First Defense® and a lower gross margin on
Wipe Out® Dairy Wipes. Our inventory balance increased by 47%, or $514,000, to $1,601,000 at
December 31, 2010 from $1,087,000 at December 31, 2009. This investment was made to help prevent a potential back log of orders. We have not experienced a back log of orders since the third quarter of 2009. We have not implemented
significant increases to our selling prices, believing that we could benefit more from higher unit sales volume than through a higher average selling price per unit.

Product Development Expenses

Product development
expenses decreased by 9%, or $152,000, to $1,493,000 during the year ended December 31, 2010, as compared to $1,645,000 during 2009. We expect higher product development expenses during the year ending December 31, 2011. If a partner
agrees to fund the completion of the Mast Out® product development effort, these expenses would be
expected to increase even higher, but only if they are off set, in part, by the funds expected to be received from a potential strategic collaboration. Product development expenses aggregated 34% and 37% of product sales in 2010 and 2009,
respectively. The majority of our product development budget from 2000 through 2010 has been focused on the development of Mast Out®. Going forward, we expect to focus our product development expenses on Mast Out® and other improvements, extensions or additions to our First Defense®product line. The other improvements, extensions, or additions to our current product line include the potential to prevent scours in calves caused by pathogens
other than those within the current First Defense® disease claims (E. coli K99 and coronavirus)
such as rotavirus. We also remain interested in acquiring other new products and technologies that fit with our sales focus on the dairy and beef industries.

Administrative Expenses

Administrative expenses decreased by approximately 3%, or $23,000, to $849,000 during the year ended December 31,
2010 as compared to $873,000 during 2009. We strive to be efficient with these expenses while funding costs associated with complying with the Sarbanes-Oxley Act of 2002 and other costs associated with being a publicly-held company. At this stage in
our development, we have limited our investment in investor relations spending. We provide a full disclosure of the status of our business and financial condition in three quarterly reports and one annual report each year. Additional information
about our business is available in our annual Proxy Statement. All of these reports are filed with the SEC and are available on-line or upon request to the Company. Presently, our financial and time resources are committed principally to managing
our commercial business and developing Mast Out®. Our Board of Directors is very involved with and
supportive of this resource allocation. While this strategy of providing cost-effective investor relations through our SEC reporting is subject to change, we believe that this focus currently is in the best long-term interest of all stockholders.

Product Selling Expenses

Product selling expenses increased by approximately 58%, or $240,000, to $651,000 in 2010, increasing to 15% of product sales in 2010 from 9% in 2009. We continue to leverage the efforts of our small
sales force through veterinary distributors. These expenses have increased due principally to a strategic decision to invest more to support First Defense®sales and to prepare for a market launch of Mast Out®. Our objective in 2011 is to maintain the ratio of product selling expenses to product sales below 20% on an annual basis.

Interest income decreased by approximately 74%, or $71,000, to $25,000 in 2010 in comparison to 2009 due principally to a decrease in interest rates. We did not incur interest expense during 2009 or 2008.
Interest expense during 2010 aggregated $22,000.

Loss Before Income Taxes and Net Loss

Our loss before income taxes of $683,000 during the year ended December 31, 2010 compares to a loss before income taxes of $429,000
during the year ended December 31, 2009. We recorded income tax benefits of 44% and 49% of the losses before income taxes during the years ended December 31, 2010 and 2009, respectively. Our net loss of $385,000, or $0.13 per share, during
the year ended December 31, 2010 compares to a net loss of $216,000, or $0.07 per share, during the year ended December 31, 2009.

Fiscal Year 2009 Compared to Fiscal Year 2008

Product Sales

Product sales for the year ended
December 31, 2009 decreased by 3%, or $123,000, to $4,506,000 from $4,628,000 in 2008. Domestic product sales decreased by 10%, or $374,000, during the year ended December 31, 2009, while international sales increased by 34%, or $252,000,
in comparison to 2008. As we introduce our products (principally First Defense®) to markets outside of
the United States, we expect some sales volatility in those territories. For example, international sales in 2008 decreased by 26% in comparison to 2007. The 2009 level of international sales was 58% higher than 2006 but 1% lower than 2007. We
believe that sales of our products were influenced by the price of milk, cows and calves and by the cost of feed as well as by the number of cows in the U.S. dairy herd.

Sales of First Defense® decreased by 4% during the year ended December 31, 2009 in comparison to 2008. Sales of First Defense® are normally seasonal, with higher sales expected during the first and fourth quarters and lower sales expected during the second and third quarters. First
Defense®continued to benefit in 2009 from wide acceptance by dairy and beef producers as an effective tool
to prevent calf scours.

Sales of Wipe Out® Dairy Wipesdecreased by 9% during the year ended December 31, 2009 in comparison to 2008. We believe that sales growth potential for Wipe Out® Dairy Wipes is limited because most of our sales of this

product tend to be to smaller dairies that are under continued financial pressures that are forcing many small dairy producers out of business.

The other products we sell primarily into the dairy industry increased to 4% of product sales during the year ended
December 31, 2009 compared to 3% of product sales during 2008. The other products we sell outside of the dairy and beef industries, principally Isolate (formerly known as Crypto-Scan®), aggregated 3% of product sales during the years ended December 31, 2009 and 2008.

We generally held our product selling prices without increase during the seven year period ended December 31,
2007. During the first quarter of 2008, we implemented a modest increase to the selling price of First
Defense®. We have implemented no significant price increases since then.

Gross Margin

Changes in the gross margin on product sales are summarized in the following table for the respective periods (in thousands, except for percentages):



|                         |  |                         |       |   |          |   |       |        |  |   |     |   |  |  |    |

|Gross margin             |  | $                       | 2,398 |   |          | $ | 2,069 |        |  | $ | 329 |   |  |  | 16 | %
|Percent of product sales |  |                         | 53    | % |          |   | 45    | %      |  |   | 8   | % |  |  | 18 | %

We
experienced an unusually low gross margin percentage during 2008 in comparison to those achieved in prior years. The gross margin as a percentage of product sales was 53% and 45% during the years ended December 31, 2009 and 2008, respectively.
This compares to gross margin percentages of 52% and 56% for the years ended December 31, 2007 and 2006, respectively. Our current annual target is to maintain the gross margin percentage at around 50%. A number of factors account for the
variability in our costs. We expect some fluctuations in gross margin percentages from quarter to quarter. The gross margin on First Defense® is affected by biological yields from our raw material, which do fluctuate over time. More generally, we are beginning to experience higher costs for production
of First Defense®and Wipe Out® Dairy Wipesdue to increased labor costs and expenses associated with our efforts to sustain compliance with cGMP regulations in our production processes. Like
most manufacturers in the U.S., we have been experiencing increases in the cost of raw materials that we purchase. Product mix also affects gross margin in that we earn a higher gross margin on First Defense® and a lower gross margin on Wipe Out® Dairy Wipes. Because First
Defense® customers are price sensitive, we had held its selling price without significant increase for about
seven years, believing that we could benefit more from higher unit sales volume than through a higher average selling price per unit. However, during the first quarter of 2008, we implemented a modest increase to the selling price of First
Defense® reflecting a part of the increase we have experienced in our labor and raw material costs.

Product Development Expenses

Product development expenses decreased by 6%, or $102,000, to $1,645,000 during the year ended December 31, 2009,
as compared to $1,746,000 during 2008. Product development expenses aggregated 37% and 38% of product sales in 2009 and 2008, respectively. The majority of our product development budget from 2000 through 2009 has been focused on the development of
Mast Out®. Going forward, we expect to focus our internally-funded product development expenses on
Mast Out® and other improvements, extensions or additions to our First Defense®product line and a sustained effort to maintain cGMP compliance in our manufacturing operations. The other
improvements, extensions, or additions to our current product line include the potential to prevent scours in calves caused by pathogens other than those within the current First Defense® disease claims (E. coli K99 and coronavirus) such as rotavirus. We also remain interested in acquiring other new products and technologies that fit with
our sales focus on the dairy and beef industries.

Administrative Expenses

Administrative expenses decreased by approximately 6%, or $54,000, to $873,000 during the year ended December 31, 2009 as compared to
$926,000 during 2008. We strive to be efficient with these expenses while funding costs associated with complying with the Sarbanes-Oxley Act of 2002 and other costs associated with being a publicly-held company.

Product Selling Expenses

Product selling expenses decreased by approximately 28%, or $159,000, to $411,000 in 2009, decreasing to 9% of product sales in 2009 from 12% in 2008. We continue to leverage the efforts of our small
sales force through veterinary distributors. As we invest more to support First Defense®sales and begin
to prepare for a market launch of Mast Out®, we anticipate an increase in these expenses. Our objective
in 2010 was to maintain the ratio of product selling expenses to product sales at approximately 15% on an annual basis.

Other Revenues (Expenses), Net

Interest income decreased by approximately 53%, or $108,000, to $96,000 in 2009 in comparison to 2008 due principally to a decrease in interest rates and a reduction in funds invested during 2009. We did
not incur interest expense in 2009 or 2008, since we repaid our outstanding bank debt in 2002. Royalty income decreased by $2,000 to just $3,000 during the year ended December 31, 2009 in comparison to 2008, as the result of less sales reported
by the firm that has licensed our milk protein purification technology. No product development grants or contracts have been applied-for or awarded since the first quarter of 2006.

Loss Before Income Taxes and Net Loss

Our loss before income taxes of $429,000 during the year ended December 31, 2009 compares to a loss before income taxes of $961,000 during the year ended December 31, 2008. We recorded income
tax benefits of 49% and 51% of the losses before income taxes during the years ended December 31, 2009 and 2008, respectively. Our net loss of $216,000, or $0.07 per share, during the year ended December 31, 2009 compares to a net loss of
$469,000, or $0.16 per share, during the year ended December 31, 2008.

Financial Condition, Liquidity and Capital Resources

We had approximately $4,626,000 in available cash and short-term investments as of December 31,
2010. We are using some of this cash to fund product development, principally Mast Out®, and to continue
a sustained investment in compliance with cGMP regulations in our manufacturing operations. We continue to look for new product acquisition opportunities that would have a strategic fit with the products that we currently sell. The table below
summarizes the changes in selected, key balance sheet items (in thousands, except for percentages):

Cash, cash equivalents and short-term investments increased by 1%, or $41,000, to
$4,626,000 at December 31, 2010 from $4,585,000 at December 31, 2009. Net cash used for operating activities amounted to $809,000 during the year ended December 31, 2010 as compared to net cash used for operating activities of
$110,000 during the year ended December 31, 2009. Capital investments of $117,000 during 2010 were funded principally by cash and maturities of short-term investments. Net working capital increased by 8%, or $497,000, to $6,441,000 at
December 31, 2010 from $5,944,000 at December 31, 2009. Total assets increased by 8%, or $766,000, to $10,751,000 at December 31, 2010 from $9,985,000 at December 31, 2009. Stockholders equity decreased by 4%, or $340,000,
to $9,282,000 at December 31, 2010 from $9,622,000 at December 31, 2009.

As part of our sustained investment in
compliance with cGMP regulations across our product lines and as we make other process improvements, we are investing in personnel, equipment and facility modifications to increase the efficiency and quality of our operations. In 2008, our Board of
Directors authorized an investment of up to approximately $1,314,000 for capital expenditures (facility modifications and production equipment). We did not increase this authorized limit during 2009 or 2010 or to date in 2011. As of
December 31, 2010, we had remaining authorization to spend up to $327,000 on capital expenditures, net of $987,000 in investments made from January 1, 2008 through December 31, 2010.

We believe that we have sufficient capital resources to meet our working capital requirements and to finance our
ongoing business operations during at least the next twelve months. The return of the Mast Out® product
rights to us has caused us to increase our spending on product development expenses that had been funded by Pfizer from 2005 to mid 2007. As expected, the expenditures on this program of product development resulted in net losses in 2010, 2009 and
2008 ending the nine consecutive years of profitability that we recorded through the year ended December 31, 2007. Continued development towards regulatory approval of Mast Out®will likely result in a net loss during the first six months of 2011 as well. We believe that our current balance of cash and short-term investments is more than
sufficient to fund our projected loss and that the commercial prospects for Mast Out® warrant this level
of investment. We expect to return to positive net operating income (before other revenues (expenses), net and income taxes) during the last six months of 2011.

Since 1999, our strategy has been focused on selling and developing products that improve animal health and productivity in the dairy and beef industries. These product opportunities are generally less
expensive to develop than the human health product opportunities that we had worked on during the 1990s. We funded most of our product development expenses principally from product sales and were profitable for each of the nine years in the
period ended December 31, 2007. During the nine years of profitability from 1999 through 2007, our cumulative investment in product development expenses of $9,894,000 was supported, in small part, by $975,000 in grant awards. The investment of
an additional $4,884,000 in product development expenses during 2008, 2009 and 2010 brings our cumulative investment to $14,778,000 during the twelve-year period ended December 31, 2010. We may, on occasion, seek additional research grant
support as a means of leveraging the funds that we are able to spend developing new products.

Critical Accounting Policies

The financial statements are presented on the basis of accounting principles that are generally accepted in the U.S. All professional accounting standards that were effective and applicable to us as of
December 31, 2010 have been taken into consideration in preparing the financial statements. The preparation of financial statements requires that we make estimates and judgments that affect the reported amounts of assets, liabilities, revenues
and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to revenue recognition, income taxes, contingencies and the useful lives and carrying values of
intangible and long lived assets. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying
values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We have chosen to highlight certain policies that we consider critical to
the operations of the business and understanding our financial statements.

We recognize revenue in accordance with Staff Accounting Bulletin (SAB) No. 104,
Revenue Recognition, which supersedes SAB No. 101, Revenue Recognition in Financial Statements. SAB No. 104 requires that four criteria are met before revenue is recognized. These include i) persuasive evidence that
an arrangement exists, ii) delivery has occurred or services have been rendered, iii) the sellers price is fixed and determinable and iv) collectibility is reasonably assured. We recognize revenue at the time of shipment (including to
distributors) for substantially all products, as title and risk of loss pass to the customer on delivery to the common carrier after concluding that collectibility is reasonably assured. We recognize service revenue at the time the service is
performed. Royalty income is recorded on the accrual basis based on sales as reported to us by our licensee pursuant to the terms of the agreement. All research and development costs and patent costs are expensed as incurred.

Inventory includes raw materials, work-in-process and finished goods and are recorded at the lower of standard cost which approximates
cost on the first-in, first-out method or market (net realizable value). Work-in-process and finished goods inventories include materials, labor and manufacturing overhead.

ITEM 7A  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We believe that neither inflation nor interest rates nor currency exchange rates have had a significant effect on our revenues and expenses. However, future increases in inflation or interest rates or the
value of the U.S. dollar could affect our customers and the demand for our products. We hedged our interest rate exposure to a $1,000,000 mortgage with an interest rate swap agreement that effectively converted a floating interest rate to the fixed
rate of 6.04%. The interest rate on our $600,000 note payable is variable. If the London Interbank Offered Rate plus 3.25% exceeds 4.25%, our interest payments will increase over the current amount. We hope to increase the level of our future sales
of products outside the United States. The cost of our products to international customers could be affected by currency fluctuations. The decline of the U.S. dollar against other currencies could make our products less expensive to international
customers. We do not anticipate that currency fluctuations will significantly affect our sales or the cost of operations.

ITEM 9  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON
ACCOUNTING AND FINANCIAL DISCLOSURE

None

ITEM 9A  CONTROLS AND PROCEDURES

Disclosure Controls and Procedures. Our management, with the participation of the individual who serves as our principal executive
and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2010. Based on this evaluation, that officer concluded that our disclosure controls and procedures were effective as of
that date. Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act (i) is recorded, processed, summarized and reported, within the
time periods specified in the SECs rules and forms and (ii) is accumulated and communicated to our management, including our principal executive and principal financial officer, as appropriate to allow timely decisions regarding required
disclosure.

Managements Annual Report on Internal Control Over Financial Reporting.The management of the
Company is responsible for establishing and maintaining adequate internal control over financial reporting. The Companys internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Management conducted an evaluation of the effectiveness of the internal controls over financial reporting based on the framework in Internal Control - Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission. This evaluation included a review of the documentation of controls, evaluation of the design effectiveness of controls, testing the operating effectiveness of the controls and a conclusion on this
evaluation. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to
financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

Management assessed the effectiveness of the Companys internal control
over financial reporting as of December 31, 2010. Based on managements assessment and those criteria, management believes that the internal control over financial reporting as of December 31, 2010 was effective.

This Annual Report does not include an attestation report of the Companys independent registered public accounting firm regarding
internal control over financial reporting. Managements internal control report was not subject to attestation by the Companys independent registered public accounting firm pursuant to rules of the Securities and Exchange Commission that
permit the Company to provide only managements report.

Changes in Internal Controls over Financial Reporting.
There was no change in our internal control over financial reporting that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders

ImmuCell Corporation

Portland, Maine

We have audited the accompanying balance sheets of ImmuCell Corporation (the Company) as of December 31, 2010 and 2009, and the related statements of operations, stockholders equity and cash
flows for each of the three years in the period ended December 31, 2010. 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. The Company is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Companys internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the
financial statements, assessing the accounting principles used and significant estimates made by management, 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 financial position of ImmuCell
Corporation as of December 31, 2010 and 2009, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2010, in conformity with U.S. generally accepted accounting principles.

|1. | BUSINESS OPERATIONS
|-- | -------------------

ImmuCell Corporations (the Company) purpose is to create scientifically-proven and practical products that result in a measurable
economic impact on animal health and productivity in the dairy and beef industries. The Company was originally incorporated in Maine in 1982 and reincorporated in Delaware in 1987, in conjunction with its initial public offering of common stock. The
Company is subject to certain risks associated with its stage of development including dependence on key individuals, competition from other larger companies, the successful sales of existing products and the development and acquisition of
additional commercially viable products with appropriate regulatory approvals, where applicable.



|2. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
|-- | ------------------------------------------



|(a) | Basis of presentation
|--- | ---------------------

We have prepared the accompanying audited financial statements reflecting all adjustments, all of which are of a normal recurring nature, that are, in our opinion, necessary in order to make the financial
statements not misleading. We follow accounting standards set by the Financial Accounting Standards Board, commonly referred to as the FASB. The FASB sets generally accepted accounting principles (GAAP) that we follow to ensure we consistently
report our financial condition, results of operations, earnings per share and cash flows. References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification (Codification). The FASB finalized the
Codification effective for periods ending on or after September 15, 2009. Certain prior year accounts have been reclassified to conform with the 2010 financial statement presentation.



|(b) | Cash, Cash Equivalents and Short-Term Investments
|--- | -------------------------------------------------

We consider all highly liquid investment instruments that mature within three months of their purchase dates to be cash equivalents. Cash equivalents are principally invested in securities backed by the
U.S. government. Amounts in excess of these FDIC limits per bank that are not invested in securities backed by the U.S. government aggregated $704,000 and $899,000 at December 31, 2009 and 2010, respectively. Certain cash balances in excess of
Federal Deposit Insurance Corporation (FDIC) limits per financial institution are maintained in money market accounts at financial institutions that are secured, in part, by the Securities Investor Protection Corporation. Short-term investments are
classified as held to maturity and are comprised principally of certificates of deposits that mature in more than three months from their purchase dates and not more than twelve months from the balance sheet date and are held at different financial
institutions that are insured by the FDIC within the FDIC insurance limit of $250,000 per institution per depositor. We are required by bank debt covenant to maintain at least $1,000,000 of otherwise unrestricted cash, cash equivalents and
short-term investments. Cash, cash equivalents and short-term investments consist of the following (in thousands):



|                          |  |                    |       |  |          |   |       |            |  |   |      |

|(c) | Trade Receivables
|--- | -----------------

Trade
receivables are carried at the original invoice amount less an estimate made for doubtful collection. Management determines the allowance for doubtful accounts on a monthly basis by identifying troubled accounts and by using historical experience
applied to an aging of accounts. Trade receivables are written off when deemed uncollectible. Recoveries of trade receivables previously written off are recorded when received. A trade receivable is considered to be past due if any portion of the
receivable balance is outstanding for more than 30 days. Interest is charged on past due trade receivables.



|(d) | Inventory
|--- | ---------

Inventory
includes raw materials, work-in-process and finished goods and is recorded at the lower of cost, on the first-in, first-out method, or market (net realizable value). Work-in-process and finished goods inventories include materials, labor and
manufacturing overhead. Inventory consists of the following (in thousands):



|                |  |                    |       |  |          |   |       |  |  |   |     |

|(e) | Property, Plant and Equipment
|--- | -----------------------------

We depreciate property, plant and equipment on the straight-line method by charges to operations in amounts estimated to expense the cost of the assets from the date they are first put into service to the
end of the estimated useful lives of the assets. The cost of the building, acquired in 1993, and the 2001 and 2007 additions thereto, are being depreciated through 2023. Related building improvements are depreciated over ten year periods. Large and
durable fixed assets are depreciated over their useful lives that are generally estimated to be ten years. Other fixed assets and computer equipment are depreciated over their useful lives that are generally estimated to be five and three years,
respectively. See Note 3.



|(f) | Intangible Assets
|--- | -----------------

We amortize intangible assets on the straight-line method by charges to operations in amounts estimated to expense the cost of the assets from the date they are first put into service to the end of the
estimated useful lives of the assets. The $250,000 acquisition of product rights related to Wipe Out® Dairy
Wipes in December 1999 was amortized to cost of sales over the ten-year period ended in December 2009, and the related manufacturing rights acquired in 2001 for $45,000 were amortized to cost of sales through December 2009. The $75,000
acquisition of product rights related to MASTiK® in July 2000 was amortized to cost of sales through June
2008. In connection with certain credit facilities entered into during the third quarter of 2010, we incurred debt issue costs of approximately $26,000, which costs are being amortized to other revenues (expenses), net over the terms of the credit
facilities.

We continually assess the realizability of these assets in accordance with the impairment provisions of
Codification Topic 360. If an impairment review is triggered, we evaluate the carrying value of long-lived assets by determining if impairment exists based on estimated undiscounted future cash flows over the remaining useful life of the assets and
comparing that value to the carrying value of the assets. If the carrying value of the asset is greater than the estimated future cash flows, the asset is written down to its estimated fair value. The cash flow estimates that are used contain our
best estimates, using appropriate and customary assumptions and projections at the time. We also review the estimated useful life of intangible assets at the end of each reporting period, making any necessary adjustments.

|(g) | Disclosure of Fair Value of Financial Instruments and Concentration of Risk
|--- | ---------------------------------------------------------------------------

Financial instruments consist mainly of cash and cash equivalents, short-term investments, accounts receivable, accounts payable, and an
interest rate swap. Financial instruments that potentially subject the Company to concentrations of credit risk are principally cash, cash equivalents, short-term investments and accounts receivable. We invest our short-term investments in financial
instruments that are insured by the FDIC. We account for fair value measurements in accordance with Codification Topic 820, Fair Value Measurements and Disclosures, which defines fair value, establishes a framework for measuring fair value
and requires additional disclosures about fair value measurements. Codification Topic 820 applies to fair value measurements that are already required or permitted by other accounting standards, except for measurements of share-based payments and
measurements that are similar to, but not intended to be, fair value and does not change existing guidance as to whether or not an instrument is carried at fair value. The adoption of this Statement did not have a material impact on our financial
condition, results of operations, earnings per share, cash flows or financial statement disclosures.

Concentration of credit
risk with respect to accounts receivable is principally limited to certain customers to whom we make substantial sales. To reduce risk, we routinely assess the financial strength of our customers and, as a consequence, believe that our accounts
receivable credit risk exposure is limited. We maintain an allowance for potential credit losses, but historically we have not experienced significant credit losses related to an individual customer or groups of customers in any particular industry
or geographic area. We did incur a net loss of $14,000 during 2010 as the result of the bankruptcy of a former distributor. The carrying amounts of our financial instruments approximate fair market value.

We believe that supplies and raw materials for the production of our products are available from more than one vendor or farm. Our policy
is to maintain more than one source of supply for the components used in our products. However, there is a risk that we could have difficulty in efficiently acquiring essential supplies.



|(h) | Interest Rate Swap Agreement
|--- | ----------------------------

As described in Note 6, we entered into an interest rate swap agreement in 2010. All derivatives are recognized on the balance sheet at their value. On the date the agreement was entered into, we
designated the derivative as a hedge of the variability of cash flows to be paid related to the long-term debt described in Note 6. The agreement has been determined to be highly effective in hedging the variability of identified cash flows, so
changes in the fair market value of the interest rate swap agreement are recorded in other comprehensive income, until earnings are affected by the variability of cash flows (e.g. when periodic settlements on a variable-rate asset or liability are
recorded in earnings). We formally documented the relationship between the interest rate swap agreement and the related hedged items. We also formally assess, both at this interest rate swap agreements inception and on an ongoing basis,
whether the agreement is highly effective in offsetting changes in cash flow of hedged items.



|(i) | Revenue Recognition
|--- | -------------------

Revenues related to the sale of manufactured products are recorded when title and risk of loss have passed to the customer, which is at
the time of shipment and when collectibility is reasonably assured. Royalty income is recognized on the accrual basis based on sales as reported to us by our licensee and is recorded as other revenues (expenses), net.



|(j) | Expense Recognition
|--- | -------------------

Advertising costs are expensed when incurred, which is generally during the month in which the advertisement is published. Advertising
expenses amounted to $140,000, $33,000 and $16,000 during the years ended December 31, 2008, 2009 and 2010, respectively. All product development expenses are expensed as incurred, as are all related patent costs.

|(k) | Income Taxes
|--- | ------------

We account
for income taxes in accordance with Codification Topic 740, Income Taxes, which requires that we recognize a current tax liability or asset for current taxes payable or refundable and a deferred tax liability or asset for the estimated future
tax effects of temporary differences and carryforwards to the extent they are realizable. We believe it is more likely than not that the deferred tax assets will be realized through future taxable income and tax effects of temporary differences
between book income and taxable income. Accordingly, we have not established a valuation allowance for the deferred tax assets. Codification Topic 740-10 clarifies the accounting for income taxes by prescribing a minimum recognition threshold that a
tax position must meet before being recognized in the financial statements. In the ordinary course of business, there are transactions and calculations where the ultimate tax outcome is uncertain. In addition, we are subject to periodic audits and
examinations by the IRS and other taxing authorities. We have evaluated the positions taken on our filed tax returns. We have concluded that no uncertain tax positions exist as of December 31, 2010. Although we believe that our estimates are
reasonable, actual results could differ from these estimates. See Note 8.



|(l) | Net Income (Loss) Per Common Share
|--- | ----------------------------------

The net income (loss) per common share has been computed in accordance with Codification Topic 260-10, Earnings Per Share. Basic net income per common share is computed by dividing net income by
the weighted average number of common shares outstanding during the period. Diluted net income per common share reflects the potential dilution from outstanding stock options as shown below. The net loss per common share has been computed by
dividing the net loss by the weighted average number of common shares outstanding during the period, without giving consideration to outstanding stock options because the impact would be anti-dilutive.

|                                                                                                    |  |                         |           |  |      |  |           |      |  |  |           | 

For additional disclosures regarding the outstanding common stock options, see Note 9(a) and 9(b).



|(m) | Employee Stock-Based Compensation
|--- | ---------------------------------

We account for the stock-based compensation in accordance with Codification Topic 718, Compensation-Stock Compensation, which generally requires us to recognize non-cash compensation expense for
stock-based payments using the fair-value-based method. The fair value of each stock option grant has been estimated on the date of grant using the Black-Scholes option pricing model, as detailed in Note 9(b). Accordingly, we recorded $55,000,
$94,000 and $30,000 of compensation expense pertaining to stock-based compensation, which resulted in an increase in loss before income taxes of approximately $0.02, $0.03 and $0.01 per share (before the effect of income taxes), during the years
ended December 31, 2008, 2009 and 2010, respectively. Codification Topic 718 requires us to reflect gross tax savings resulting from tax deductions in excess of expense reflected in our financial statements as a financing cash flow, but there
were no significant tax deductions during the three years in the period ended December 31, 2010.

|(n) | Use of Estimates
|--- | ----------------

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

|6. | BANK DEBT
|-- | ---------

During the
third quarter of 2010, we agreed to terms of certain credit facilities with TD Bank, N.A. aggregating up to approximately $2,100,000, which are secured by substantially all of our assets. These credit facilities are comprised of a $1,000,000
ten-year mortgage loan, a $600,000 fifty-four month note payable and a $500,000 line of credit, which is renewable annually. Proceeds from the $1,000,000 mortgage were received during the third quarter of 2010. Based on a 15-year amortization
schedule, a balloon principal payment of approximately $452,000 will be due in the third quarter of 2020. We hedged our interest rate exposure on this mortgage with an interest rate swap agreement that effectively converted a floating interest rate
to the fixed rate of 6.04%. The original notional amount of the interest rate swap agreement of $1,000,000 amortizes in accordance with the amortization of the mortgage. As the result of our decision to hedge this interest rate risk, we recorded a
credit to equity in the amount of approximately $10,000 to reflect the fair value of the interest rate swap asset as of December 31, 2010. The fair value of the interest rate swap has been determined using observable market-based inputs or
unobservable inputs that are corroborated by market data. Accordingly, the interest rate swap is classified as level 2 within the fair value hierarchy provided in Codification Topic 820, Fair Value Measurements and Disclosures. Proceeds from
the $600,000 note payable were received during the first quarter of 2011. The $500,000 line of credit is available as needed. Interest on the loan and the line of credit will be variable at the higher rate of 4.25% or the one month London Interbank
Offered Rate (LIBOR) plus 3.25% for the $600,000 note payable or the one month LIBOR plus 3.50% for the $500,000 line of credit. These credit facilities are subject to certain financial covenants. A technical non-compliance with one of these
covenants as of December 31, 2010 was waived by the bank. Because these covenants were calculated anticipating much higher spending on product development expenses than we currently plan, we expect to be in compliance with these covenants going
forward. Principal payments due under debt outstanding as of December 31, 2010 are reflected in the following table by the year that payments are due (in thousands):

|8. | INCOME TAXES
|-- | ------------

We account
for income taxes in accordance with Codification Topic 740, Income Taxes, which requires that we recognize a current tax liability or asset for current taxes payable or receivable and a deferred tax liability or asset for the estimated future
tax effects of temporary differences and carryforwards to the extent they are realizable. We believe it is more likely than not that the deferred tax assets will be realized through the future tax effects of temporary differences and through future
taxable income. Accordingly, we have not established a valuation allowance for the deferred tax assets. Our income tax benefit aggregated $492,000, $212,000 and $299,000 (51%, 49% and 44% of the loss before income taxes, respectively) for the years
ended December 31, 2008, 2009 and 2010, respectively. The income tax provision consists of the following (in thousands):

In order to accelerate the utilization of available net operating loss carryforwards in advance of their
expiration dates, we elected to increase income for federal income tax purposes by capitalizing research and experimentation expenditures aggregating $1,731,000 for our 2000 and 2001 tax returns. Accordingly, we recorded amortization of these
capitalized expenditures of approximately $90,000 in 2000 and $173,000 in each of the nine years ended December 31, 2009 and $84,000 for the year ending December 31, 2010 for tax return purposes only. We carried back our 2008 federal net
operating loss of approximately $1,151,000 to previous years for tax return purposes, and we have a state net operating loss carryforward of approximately $2,561,000 that expires in 2028, 2029 and 2030, if not utilized before then, and a federal net
operating loss carryforward of approximately $1,395,000 that expires in 2029 and 2030, if not utilized before then. The $1,500,000 licensing payment that we received in December 2004 was treated as taxable income in 2004, for tax return purposes
only. The $965,000 licensing payment that we made in November 2004 was treated as an intangible asset and is being amortized over 15 years, for tax return purposes only.

|9. | STOCKHOLDERS EQUITY
|-- | --------------------



|(a) | Stock Option Grants Outside of Stock Option Plans
|--- | -------------------------------------------------

On March 1, 1999, 31,100 non-qualified stock options were issued to each of the three then-serving executive officers at an exercise price of $1.31 per share, the then current market price of our
common stock, vesting as to one-third in each of March 2000, 2001 and 2002. These options were granted outside of the stock option plans described below. In 2000, 20,734 of these options terminated when one of the officers separated from the
Company. In September 2001, that former officer exercised 10,300 of these options and 66 of these options expired without being exercised. In February 2009, the aggregate of 34,200 of the outstanding options were exercised by two current executive
officers and the remaining 28,000 of these options expired without being exercised. The aggregate intrinsic value of these outstanding options approximated $22,000 as of December 31, 2008.



|(b) | Stock Option Plans
|--- | ------------------

In
May 1989, the stockholders approved the 1989 Stock Option and Incentive Plan (the 1989 Plan) pursuant to the provisions of the Internal Revenue Code of 1986, under which employees may be granted options to purchase shares of the
Companys common stock at i) no less than fair market value on the date of grant in the case of incentive stock options and ii) no less than 85% of fair market value on the date of grant in the case of non-qualified stock options. Vesting
requirements are determined by the Compensation and Stock Option Committee of the Board of Directors on a case by case basis. All options granted under the 1989 Plan expire no later than ten years from the date of grant. The 1989 Plan expired in
March 1999, and no further options may be granted under the 1989 Plan. The last 41,800 options under the 1989 plan were exercised in February 2009 in accordance with their terms.

In June 2000, the stockholders approved the 2000 Stock Option and Incentive Plan (the 2000 Plan) pursuant to the provisions
of the Internal Revenue Code of 1986, under which employees and certain service providers may be granted options to purchase shares of the Companys common stock at i) no less than fair market value on the date of grant in the case of incentive
stock options and ii) no less than 85% of fair market value on the date of grant in the case of non-qualified stock options. Vesting requirements are determined by the Compensation and Stock Option Committee of the Board of Directors on a case by
case basis. Originally, 250,000 shares of common stock were reserved for issuance under the 2000 Plan. The stockholders of the Company approved an increase in this number to 500,000 shares in June 2001. All options granted under the 2000 Plan expire
no later than ten years from the date of grant. The 2000 Plan expired in February 2010, after which date no further options may be granted under the 2000 Plan. However, outstanding options under the 2000 Plan may be exercised in accordance with
their terms.

In June 2010, the stockholders approved the 2010 Stock Option and Incentive Plan (the 2010 Plan)
pursuant to the provisions of the Internal Revenue Code of 1986, under which employees and certain service providers may be granted options to purchase shares of the Companys common stock at i) no less than fair market value on the date of
grant in the case of incentive stock options and ii) no less than 85% of fair market value on the date of grant in the case of non-qualified stock options. Vesting requirements are determined by the Compensation and Stock Option Committee of the
Board of Directors on a case by case basis. At that time, 300,000 shares of common stock were reserved for issuance under the 2010 Plan. All options granted under the 2010 Plan expire no later than ten years from the date of grant.

At December 31, 2010, 273,500 shares of common stock were reserved for future issuance under
all outstanding stock options described above, and an additional 275,500 common shares were reserved for the potential issuance of stock options in the future under the 2010 Plan. The weighted average remaining life of the options outstanding under
the 2000 Plan and the 2010 Plan as of December 31, 2010 was approximately six years and seven months. The exercise price of the options outstanding and of the options exercisable as of December 31, 2010 ranged from $1.70 to $7.00 per
share. Of the 44,000 stock options granted during 2008, 24,000 had exercise prices between $3.00 and $3.18 per share and 20,000 had exercise prices between $3.35 and $3.75 per share. Of the 115,000 stock options granted during 2009, 95,000 had an
exercise price of $1.70 per share, 15,000 had exercise prices between $2.55 and $2.94 per share and 5,000 had an exercise price of $3.99 per share. The 45,500 stock options granted during 2010 had exercise prices between $3.15 and $3.99 per share.
The aggregate intrinsic value of options exercised during 2008, 2009 and 2010 approximated $7,000, $3,000 and $3,000, respectively. The weighted-average grant date fair values of options granted during 2008, 2009 and 2010 were $1.35, $0.81 and $1.45
per share, respectively. The fair value of each stock option grant has been estimated on the date of grant using the Black-Scholes option pricing model, for the purpose discussed in Note 2(m), with the following weighted-average assumptions:



|                        |  |      |         |   |      |  |         |      |  |  |         |

|Risk-free interest rate |  |      | 2.8     | % |      |  | 1.7     | %    |  |  | 2.4     | %

|Expected volatility     |  |      | 43.7    | % |      |  | 44.9    | %    |  |  | 44.2    | %
|Expected life           |  |      | 5 years |   |      |  | 5 years |      |  |  | 5 years |  

As of
December 31, 2010 total unrecognized compensation costs related to non-vested stock-based compensation arrangements aggregated approximately $86,000. That cost is expected to be recognized at a declining rate through December 31, 2013
which represents the remaining vesting period of the outstanding non-vested stock options.

|(c) | Stock Option Exercises
|--- | ----------------------

During the year ended December 31, 2008, one employee exercised stock options covering 5,000 shares. These options were exercised by
the surrender of 2,824 shares of common stock with a fair market value of $9,700 at the time of exercise. During the year ended December 31, 2009, four employees exercised stock options covering the aggregate of 76,000 shares. These options
were exercised for cash, resulting in total proceeds of $99,750. During the year ended December 31, 2010, three employees exercised 1,000 stock options each covering the aggregate of 3,000 shares. These options were exercised for cash,
resulting in total proceeds of $6,000.



|(d) | Common Stock Rights Plan
|--- | ------------------------

In September 1995, our Board of Directors adopted a Common Stock Rights Plan and declared a dividend of one common share purchase right (a
Right) for each of the then outstanding shares of the common stock of the Company. Each Right entitles the registered holder to purchase from the Company one share of common stock at an initial purchase price of $70.00 per share, subject
to adjustment. The description and terms of the Rights are set forth in a Rights Agreement between the Company and American Stock Transfer & Trust Co., as Rights Agent.

The Rights become exercisable and transferable apart from the common stock upon the earlier of i) 10 days following a public announcement
that a person or group (acquiring person) has, without the prior consent of the Continuing Directors (as such term is defined in the Rights Agreement), acquired beneficial ownership of 15% or more of the outstanding common stock (which amount was
later increased by amendment to 18%, as discussed below) or ii) 10 days following commencement of a tender offer or exchange offer the consummation of which would result in ownership by a person or group of 20% or more of the outstanding common
stock (the earlier of such dates being called the Distribution Date).

Upon the acquisition of 15% or more of the
Companys common stock by an acquiring person, the holder of each Right not owned by the acquiring person would be entitled to purchase common stock having a market value equal to two times the exercise price of the Right (i.e., at a 50%
discount). If, after the Distribution Date, the Company should consolidate or merge with any other entity and the Company were not the surviving company, or, if the Company were the surviving company, all or part of the Companys common stock
were changed or exchanged into the securities of any other entity, or if more than 50% of the Companys assets or earning power were sold, each Right would entitle its holder to purchase, at the Rights then-current purchase price, a
number of shares of the acquiring companys common stock having a market value at that time equal to twice the Rights exercise price.

At any time after a person or group becomes an acquiring person and prior to the acquisition by such person or group of 50% or more of the outstanding common stock, the Board of Directors of the Company
may exchange the Rights (other than Rights owned by such person or group which have become void), in whole or in part, at an exchange ratio of one share of common stock per Right (subject to adjustment). At any time prior to 14 days following the
date that any person or group becomes an acquiring person (subject to extension by the Board of Directors), the Board of Directors of the Company may redeem the then outstanding Rights in whole, but not in part, at a price of $0.005 per Right,
subject to adjustment.

On June 8, 2005, our Board voted to authorize an amendment of the Rights Agreement to extend the
Final Expiration Date by an additional three years, to September 19, 2008. As of June 30, 2005, we entered into an amendment to the Rights Agreement with the Rights Agent reflecting such extension. No other changes were made to the terms
of the Rights or the Rights Agreement at that time. On June 6, 2008 our Board voted to authorize an amendment of the Rights Agreement to extend the Final Expiration Date by an additional three years, to September 19, 2011 and to increase
the ownership threshold for determining Acquiring Person status from 15% to 18%. As of June 30, 2008, we entered into an amendment to the Rights Agreement with the Rights Agent reflecting such extension and threshold increase. No
other changes were made to the terms of the rights or the Rights Agreement.

|10. | COMMITMENTS AND CONTINGENT LIABILITIES
|--- | --------------------------------------

In connection with a Development and Manufacturing Agreement entered into during the third quarter of 2010 with Lonza Sales Ltd., we have committed approximately an additional $567,000 (50% paid during
the fourth quarter of 2010 and the balance due upon completion) to Lonza to generate the manufacturing data required for a regulatory submission to the FDA pertaining to the development of Mast
Out®. Approximately 27% of this work was complete as of December 31, 2010, and, accordingly, we
expensed approximately $155,000 to product development expenses during 2010 on the percentage of completion basis. This work is expected to be completed during the first six months of 2011. This commitment is in addition to approximately $137,000
that we paid to Lonza during the fourth quarter of 2009, of which approximately 71%, or approximately $98,000, was expensed prior to 2011 on the percentage completion basis. This work is expected to be completed during the first six months of 2011.

We committed approximately $65,000 to subcontractors for work necessary to complete certain facility projects that were
incomplete as of December 31, 2010.

Our By-Laws, as amended, in effect provide that the Company will indemnify its
officers and directors to the maximum extent permitted by Delaware law. In addition, we make similar indemnity undertakings to each director through a separate indemnification agreement with that director. The maximum payment that we may be required
to make under such provisions is theoretically unlimited and is impossible to determine. We maintain directors and officers liability insurance, which may provide reimbursement to the Company for payments made to, or on behalf of,
officers and directors pursuant to the indemnification provisions. Our indemnification obligations were grandfathered under the provisions of Codification Topic 460, Guarantees. Accordingly, we have recorded no liability for such obligations
as of December 31, 2010. Since our incorporation, we have had no occasion to make any indemnification payment to any of our officers or directors for any reason.

We enter into agreements with third parties in the ordinary course of business under which we are obligated to indemnify such third parties for and against various risks and losses. The precise terms of
such indemnities vary with the nature of the agreement. In many cases, we limit the maximum amount of our indemnification obligations, but in some cases those obligations may be theoretically unlimited. We have not incurred material expenses in
discharging any of these indemnification obligations, and based on our analysis of the nature of the risks involved, we believe that the fair value of these agreements is minimal. Accordingly, we have recorded no liabilities for these obligations as
of December 31, 2010.

The development, manufacturing and marketing of animal health care products entails an inherent
risk that liability claims will be asserted against us. We feel that we have reasonable levels of liability insurance to support our operations.



|11. | SEGMENT AND SIGNIFICANT CUSTOMER INFORMATION
|--- | --------------------------------------------

We principally operate in the business segment described in Note 1. Pursuant to Codification Topic 280, Segment Reporting, we operate in one reportable business segment, that being the development,
acquisition, manufacture and sales of products that improve the health and productivity of cows for the dairy and beef industries. Almost all of our internally funded product development expenses are in support of such products. The significant
accounting policies of this segment are described in Note 2.

|15. | SUBSEQUENT EVENTS
|--- | -----------------

We
have adopted the disclosure provisions of Codification Topic 855-10-50-1, Subsequent Events, which provides guidance to establish general standards of accounting for and disclosures of events that occur after the balance sheet date but before
financial statements are issued. Entities are required to disclose the date through which subsequent events were evaluated as well as the rationale for why that date was selected. This disclosure should alert all users of financial statements that
an entity has not evaluated subsequent events after that date in the set of financial statements being presented. Codification Topic 855-10-50-1 requires additional disclosures only, and therefore did not have an impact on our financial condition,
results of operations, earnings per share or cash flows. Public entities must evaluate subsequent events through the date that financial statements are issued. Accordingly, we have evaluated subsequent events through the time of filing on
March 28, 2011, the date we have issued this Annual Report on Form 10-K.
