ITEM 1.  BUSINESS

GENERAL

         Embrex, Inc. ("Embrex" or the "Company") is a North Carolina
corporation that develops and markets bioscience and bioengineering-based
products to increase the productivity and profitability of the global poultry
industry. The Company was incorporated in 1985.

         Embrex has developed and commercialized a proprietary automated egg
injection and transfer system which can inoculate 20,000 to 50,000 eggs per hour
and eliminate the need for manual post-hatch injection, the current procedure in
virtually all hatcheries in the U.S. that have not converted to the use of
Embrex's system. This proprietary system, called the INOVOJECT(R), is designed
to inject vaccines and other compounds in precisely calibrated volumes into
targeted compartments within the egg. Embrex markets the INOVOJECT(R) system to
commercial poultry producers, charging a fee for each egg injected.

         In addition to the INOVOJECT(R) system, Embrex has developed and is
marketing a Viral Neutralizing Factor antibody useful in the development of
certain avian vaccines. Embrex also is developing various other proprietary
pharmaceutical and biological products to improve bird health, reduce bird
production costs and provide other economical benefits to the poultry industry.
These compounds include vaccines, immune enhancers, performance modifiers,
antimicrobials and genetic materials designed to increase poultry productivity
and health while reducing costs. These products are in various stages of
development, and some are being developed in collaboration with major drug
companies, the USDA, and several leading universities in the field of avian
science. These compounds can be delivered through the INOVOJECT(R) system and,
alternatively, some can be administered via post-hatch injection.

EXISTING PRODUCTS

         Patented Egg Injection System (INOVOJECT(R))

         Embrex has developed and commercialized a proprietary automated egg
injection and transfer system which can inoculate 20,000 to 50,000 eggs per hour
and eliminate the need for manual post-hatch injection, the current procedure in
virtually all hatcheries in the U.S. that have not converted to the use of
Embrex's system. This proprietary system, called INOVOJECT(R), is designed to
inject vaccines and other compounds in precisely calibrated volumes into
targeted compartments within the egg. Embrex markets the INOVOJECT(R) system to
commercial poultry producers, charging a fee for each egg injected.

         In 1996, the Company converted a number of hatcheries to the
INOVOJECT(R) egg injection system and continued operations of INOVOJECT(R)
systems in hatcheries converted prior to 1996. As a result, at December 31,
1996, Embrex had over 250 INOVOJECT(R) systems installed in the United States
("U.S.") and Canada, as compared with 235 at year end 1995.

         During 1996, the Company also placed a number of INOVOJECT(R) systems
for trial and on contract at locations outside the U.S. and Canada. The
Company's expansion outside the U.S. and Canada has been focused initially on
Europe. At year end, the Company had INOVOJECT(R) systems either installed or on
trial in England, Ireland, France, Spain, the Netherlands, Belgium, Italy, 
Israel, Egypt, South Africa, Turkey and Australia. Overall, the placement 
of INOVOJECT(R) systems outside the U.S. and Canada is dependent on market 
acceptance of various in ovo vaccines and obtaining regulatory approval of 
these vaccines in numerous countries.

         Certain poultry diseases are more prevalent in some geographic regions
than in others. For example, Marek's disease, for which the INOVOJECT(R) system
is used in the U.S., is not as widespread in Europe as in North America.
Similarly, Gumboro disease (also known as infections bursal disease) is
prevalent both in the United States and in

                                       3
<PAGE>


Northern Europe and Asia. The Company expects that primary usage of its
INOVOJECT(R) systems will vary by geographic region according to the prevailing
diseases.

         Viral Neutralizing Factor ("VNF")

         Embrex has developed and commercialized a Viral Neutralizing Factor
("VNF") technology which permits single dose immunization of the avian embryo
effective for the life of the bird. By combining VNF, an antibody, with a
vaccine virus, immunization is provided in a single step, reducing or
eliminating many of the multiple vaccinations carried out in the industry. VNF
can neutralize a virulent vaccine virus without impairing the virus' ability to
stimulate an immune response. By using VNF in this manner, the virulent vaccine
virus can be made into a safe and effective vaccine which can be used at or
before hatching.

         The VNF technology is the subject of two issued U.S. patents, a pending
U.S. patent application, and several foreign patents and foreign patent
applications. The U.S. patents are owned by the University of Arkansas and
exclusively licensed to Embrex on a royalty basis for the life of the patents.
Embrex sells VNF and sublicenses the VNF technology to infectious bursal disease
("IBD") vaccine manufacturers for the production of improved IBD vaccines for
both in ovo ("in the egg") and post-hatch use. Embrex also is researching 
application of VNF for other avian disease vaccines, including for Newcastle's 
disease, although there is no assurance such research will result in product 
opportunities.

         To date, the Company's research efforts with its VNF compound have been
focused on avian uses. Based on initial experimental data, the Company now
believes that the potential exists for VNF to be used in several non-avian
species. The Company is in the early stages of exploring collaborative
relationships with other companies for the development and licensing of VNF for
non-avian uses. Embrex has not initiated any regulatory approval processes with
respect to non-avian uses of VNF, nor is there any assurance that its efforts in
this area will result in products or collaborative agreements.

         Infectious Bursal Disease ("IBD") Vaccines

         VNF is especially useful in vaccines against avian IBD, which weakens a
bird's immune system. Birds infected by IBD typically exhibit poor growth or can
succumb to other diseases because of a compromised immune system. This disease
is widespread in the U.S., Northern Europe and Asia. VNF renders a virulent IBD
vaccine both safe and effective, thus allowing its use at or before hatch.

         In January 1995, Sanofi Animal Health, Inc. ("Sanofi") received
approval from the United States Department of Agriculture (the "USDA") for an
IBD vaccine containing Embrex's VNF for post-hatch use. Under the terms of a
1991 agreement, Embrex was to sell VNF to Sanofi, which was to manufacture and
market the vaccine. In 1995, Sanofi was acquired by Rhone Merieux SA. In January
1996, Embrex entered into an agreement with Select Laboratories, Inc.
("Select"), a wholly-owned subsidiary of Rhone Merieux SA, under which Embrex
took over the ownership and marketing from Select of the IBD vaccine containing
Embrex's VNF, known as "BURSAPLEX(TM)" (previously known as "BDA-Blen"), and
Select agreed to manufacture BURSAPLEX(TM) for Embrex on a contract basis for at
least two years. Under the agreement, Embrex will market BURSAPLEX(TM) in North
America, South America and Asia, upon receipt of appropriate regulatory
approvals. Additionally, Embrex has agreed to purchase all existing inventories
of raw material, BURSAPLEX(TM), and related materials within thirty months
following the receipt of in ovo approval of the product by the USDA, which
occurred on January 20, 1997. The Company contemplates that all of these
materials will be purchased in the form of finished goods. This purchase
commitment totals approximately $1.6 million, of which $400,000 was paid upon
execution of the agreement and $125,000 was paid following in ovo approval on
January 20, 1997.

         In August 1995, the Company entered into an agreement with Cyanamid
Websters ("Webster"), a subsidiary of American Home Products, Inc., for the
joint development of another IBD vaccine containing VNF, which will be marketed
by Webster in Europe, the Middle East, and Africa under the trade name
"Bursamune(TM)."

         On January 20, 1997, the Company received U.S. Department of
Agriculture approval for in ovo use of the Company's VNF based vaccine for IBD
in broiler chickens. The approval is specifically for in ovo (as opposed to
post-


                                       4
<PAGE>

hatch) administration of the vaccine complex via Embrex's patented INOVOJECT(R)
egg injection systems. To date, IBD has been treated post-hatch via manually
delivered vaccines or in drinking water. The Company estimates the worldwide
market for IBD vaccines to be $40 million. Existing vaccines are associated,
however, with certain limitations, and some cannot be used safely or effectively
in ovo.

         Embrex intends to seek regulatory approval in selected Latin American
and Asian markets for in ovo use of BURSAPLEX(TM). Embrex is beginning to
initiate this process, but there is no assurance that any such regulatory
approvals will be obtained. Moreover, the placement of INOVOJECT(R) systems
outside the U.S. and Canada is dependent on market acceptance of various in ovo
vaccines.

PRODUCTS UNDER DEVELOPMENT

         Embrex is developing individually and in collaboration with others
additional products which address poultry health and performance needs when
administered in ovo. These additional products are in various stages of
development. There can be no assurance that Embrex will successfully develop or
market any of these products. Marketing products developed jointly with others
may require royalty or other payments by Embrex to its co-developers. Embrex has
not initiated the regulatory approval process for any of these potential
products, and there is no assurance regulatory approval will be obtained.

         In Ovo Products for Control of Coccidiosis

         In 1995, the Company began an initiative aimed at development of a
novel in ovo biological control method for coccidiosis. Coccidiosis is caused by
a protozoan parasite which attacks the gut of the chicken, causing significant
problems with the intake and digestion of feed and, therefore, the physical and
economic performance of the bird. Currently, virtually all broiler chickens, and
most poultry in general, receive anti-coccidiosis compounds called coccidiostats
incorporated into poultry feed. Over the years, coccidia have developed levels 
of resistance to these coccidiostats and thus effectiveness has been somewhat
reduced. A limited number of live vaccines have also been developed and are
administered orally soon after hatch. However, due to difficulties in providing
a precise oral dose to each bird, growth depression can occur in broiler flocks.
Therefore, such live vaccines are used primarily in parent stock. Using its
INOVOJECT(R) technology and its knowledge of avian embryology, the Company has
begun this initiative to develop a novel, efficacious and cost-effective means
of preventing coccidiosis in broiler chickens, aimed at overcoming many of the
problems associated with current practices.

         Embrex's initial experiments with in ovo delivery of certain early
stage coccidiosis antigens have shown that broilers immunized in ovo with
coccidiosis antigens are better protected against coccidiosis as compared to
broilers immunized post-hatch with the same coccidiosis antigens. There can be
no assurances that any of these development efforts will be successful. Embrex
has not initiated the regulatory approval process with respect to these
development efforts, and does not expect for any coccidiosis product developed
by the Company to reach the market in the near future.

         In Ovo Products for Control of Salmonella

         Salmonella bacteria are widespread in nature and difficult to control.
With the 1996 adoption of the USDA's Hazard Analysis Critical Control Points
(HACCP) regulations, poultry producers are obliged to implement systems to
minimize contamination of meat by specific salmonella which reside in the
intestinal tract of chickens and are harmless to the bird, but which are capable
of inducing an illness (typically gastrointestinal) in humans. Newly hatched
chicks can be first exposed to salmonella very early in the hatchery
environment. Consequently, the Company believes that the earliest delivery of a
variety of agents, such as competitive exclusive agents or various vaccines,
would be best administered in ovo. Embrex continues to explore, through
collaborative relationships with the USDA and others, various products to reduce
salmonella contamination. There can be no assurance that development of such
products will be successful or that regulatory approval will be available.
Embrex has not initiated the regulatory approval process with respect to such
products.

                                       5

         Other Products Under Development

         In February 1996, the Company signed an agreement with Solvay S.A.
("Solvay") of Belgium to collaborate on the use of vaccines manufactured by
Solvay together with Embrex's proprietary in ovo delivery technology. The
territories specified include Europe, the Middle East, and Africa. Under the
agreement, Embrex and Solvay will work together to introduce and establish the
use of appropriate in ovo vaccines currently being adapted or developed by
Solvay for sale to poultry producers, via Embrex's INOVOJECT(R) system, and to
extend the use of the Embrex equipment throughout the territories concerned.

         During 1996, Embrex continued the evaluation process for several
compounds which the Company believes may have the potential to yield
improvements in the areas of feed conversion, muscle mass and leanness within
broiler chickens. These compounds need to be administered in the first several
days of embryonic development in order to have the desired effect. The Company
plans to continue its research efforts in this area in 1997. The effectiveness
of these compounds has not been confirmed, and there is no assurance that these
efforts will yield product opportunities.

         Embrex also is researching technology alternatives to enhance or
automate sexing and gender sorting practices for poultry. Early gender
sorting improves processing plant efficiencies by enabling gender-specific
feed rations and improved feed conversion. There is no assurance such research
will result in product opportunities.

         Embrex routinely enters into collaborative agreements with various
animal health companies, pharmaceutical companies and research and academic
institutions to evaluate the utility of certain of their compounds or devices
when delivered or applied in ovo. Depending upon the outcome of these tests,
Embrex may or may not proceed with these collaborations for further development.
There is no assurance that these efforts will yield products or further
collaborations.

PATENTS AND PROPRIETARY RIGHTS

         Embrex controls (either through direct ownership or exclusive license)
18 issued U.S. patents, 15 pending U.S. patent applications and over 34 issued
foreign patents and 60 pending foreign patent applications. In addition, Embrex
has executed confidentiality agreements with its employees, consultants,
collaborators, subcontractors and directors.

         The process utilized by the INOVOJECT(R) system of injecting viral,
bacterial, or fungal vaccines into an avian embryo was patented in the U.S. by
the USDA in 1984. Embrex holds an exclusive license to this patent through its
expiration in June 2002. Embrex has supplemented the USDA patent with five
separately issued U.S. patents (and multiple foreign patents and patent
applications) covering certain design features of the INOVOJECT(R) system.
Embrex owns or licenses method-of-use patents which have been filed for the in
ovo administration of VNF and numerous other molecules. Two U.S. patents for
methods of treating IBD virus infections using VNF, including in ovo use, were
issued in March 1995. These patents and patent applications cover the use of
these compounds to elicit various beneficial responses in poultry and are
independent of the source of the compounds. Through licenses, Embrex has
complemented the method-of-use patents and applications with issued
composition-of-matter patents for VNF-vaccine compositions. These patents cover
the composition of matter used to elicit a beneficial effect, regardless of the
manner in which they are used.

         In 1996, six additional U.S. patent applications were made covering
various aspects of in ovo biotechnology.

         Embrex has begun a continuing effort to patent delivery methods
focusing on applications of in ovo technology relying upon early intervention
methods and devices. In August 1995, a second patent on early delivery was
issued in the U.S., complementing an earlier patent obtained in August 1994.

         In addition, Embrex owns the federally registered trademarks EMBREX(R),
INOVOJECT(R), and OVOVAC(R), and has applied for federal registration of the VNF
logo, BURSAPLEX(TM) and FORTIMUNE(TM) trademarks.

FINANCING

         During 1996, Embrex utilized a total of $2.1 million in existing lease
and other collateralized equipment financing, which the Company accounts for as
capital leases, to support the purchase of the Company's INOVOJECT(R) egg
injection systems. The Company, in turn, leases the INOVOJECT(R) systems to its
customers under multi-year contracts.

                                       6
<PAGE>

At December 31, 1996, an aggregate of $2.0 million remained available for
utilization by Embrex under this financing arrangement.

         In September 1996, the Company obtained a $2.0 million secured line of
credit from a bank in the United Kingdom, which will be used to finance the
construction of additional INOVOJECT(R) systems for Europe, the Middle East and
Africa. The Company utilized $0.4 million of this line in 1996, with the balance
of $1.6 million available at year end.

COMPETITION

         Embrex continues to monitor the presence of any competitive in ovo
administration system. See Item 3, "Legal Proceedings," below. The primary
competition for the INOVOJECT(R) system is the conventional, manual, post-hatch
administration of biological products. As most of Embrex's potential products
are being designed to be administered through the INOVOJECT(R) system, the
INOVOJECT(R) system must continue to develop market acceptance within the
poultry industry and operate as intended under long-term commercial conditions
in order for these potential products to be marketed successfully.

         Competitive success for Embrex will be based primarily on commercial
acceptance of its products, achieving and retaining scientific expertise and
technological superiority, identifying and pursuing scientifically feasible and
commercially viable opportunities, obtaining proprietary protection for its
research achievements, obtaining adequate funding and timely regulatory
approvals, and attracting corporate sponsors or partners in developing, testing,
producing, and marketing products, none of which can be assured. In addition, a
primary competitive factor affecting Embrex is its ability to conduct research
and development. Maintaining financial and human resources, therefore, are
important factors for success. Embrex's ability to compete also is dependent on
its ability to attract and retain key personnel.

PRODUCTION, MARKETING AND DISTRIBUTION

         
Production

         Embrex currently subcontracts the production of substantially all of
its mechanical and biological products and expects to continue to do so for the
foreseeable future. The Company believes that alternative sources of manufacture
and supply generally exist.

         INOVOJECT(R)  System

         Embrex's in-house engineering staff designs the INOVOJECT(R) system,
which incorporates proprietary mechanical, pneumatic and electronic sub-systems
and concepts. Embrex subcontracts with equipment manufacturers to build the
INOVOJECT(R) systems. The Company uses a single contract manufacturer to
fabricate its INOVOJECT(R) systems. While other machine fabricators exist and
have constructed limited numbers of INOVOJECT(R) systems, a change in
fabricators could cause a delay in manufacturing and a possible delay in the
timing of future INOVOJECT(R) installations and revenues from those
installations.

         VNF (Viral Neutralizing Factor)

         In 1993, Embrex signed multi-year agreements with SPAFAS, Inc., a
subsidiary of Charles River Laboratories, Inc., and Hy-Vac Laboratory Eggs
Company, a division of the German-based Lohmann Group, under which the two
companies will supply the active ingredient in VNF. In connection with these
agreements, Embrex maintains appropriate inventory levels and places orders with
these companies to allow Embrex to satisfy anticipated customer demand for VNF.
The regulatory approval granted by the USDA for BURSAPLEX(TM) in January 1997
specifically covers the vaccine produced with SPAFAS-manufactured VNF. The
Company does not intend to use its remaining inventories of Hy-Vac produced VNF
domestically and, accordingly, wrote off $160,000 as the value of this inventory
in December 1996.

         Marketing and Distribution

         Because of the geographical and industrial concentration of the poultry
industry in the U.S., Embrex markets its products and provides ongoing service
directly to the industry. Embrex's marketing is focused principally on the
broiler chicken segment of the poultry industry, but the Company also has
adapted its products for use by and initiated trials and entered into commercial
contracts with a limited number of turkey producers.

         In order to encourage proper use of the INOVOJECT(R) system technology
within an appropriate production environment, Embrex leases and licenses
INOVOJECT(R) units to hatcheries. The agreements cover the use of the mechanical
equipment and ongoing field service, maintenance and technical support. The
agreements also include a license with royalty fees for use of Embrex's
proprietary injection process. Products which are delivered in ovo are sold
separately.

         Embrex has initiated activities necessary for the commercialization of
its technology in Japan. In 1992, Embrex entered into a distribution agreement
with Ishii Company, Ltd. ("Ishii"), a leading chick producer and the dominant
supplier of hatchery equipment in Japan. Upon veterinary medical device
regulatory approval by the Japanese Ministry of Agriculture, Fisheries and
Forestry, Ishii intends to distribute the INOVOJECT(R) egg injection system to
poultry producers throughout Japan.

         The Company also is initiating arrangements for international
distribution of IBD vaccines, subject in each case to the availability of
required regulatory approvals. In August 1995, the Company entered into an
agreement with Cyanamid Websters, a subsidiary of American Home Products, Inc.,
providing Cyanamid Websters the right to develop, manufacture and market an in
ovo IBD vaccine containing VNF in Europe, the Middle East and Africa. In 1996,
the Company entered into agreements with other parties to distribute
BURSAPLEX(TM) in Israel, Chile, Peru and Pakistan. The agreement for Israel also
entitles the distributor to manufacture a VNF-based IBD vaccine. Subject to
these agreements, the Company also will conduct international marketing
directly.

         Other significant poultry markets exist in Asia and Latin America.
Embrex has held a number of discussions regarding marketing and distribution in
each of these markets.

         The Company's revenues attributable to international operations in
1996, 1995 and 1994 were 10%, 6% and 2% of the Company's consolidated revenues,
respectively. The company's identifiable assets attributable to international
operations in 1996, 1995 and 1994 were 13%, 5% and 4% of the Company's
consolidated assets, respectively.

RESEARCH AND DEVELOPMENT

         Research and development expense was $4.3 million in 1994, $3.4 million
in 1995 and $3.7 million in 1996. The decrease in research and development
expense from 1994 to 1995 and the increase from 1995 to 1996 largely reflect
variances in outside contract research, supplies consumption, and INOVOJECT(R)
design and development activity. Research and development is principally Company
sponsored and funded primarily from internal sources.

GOVERNMENTAL REGULATION

         Regulation by governmental authorities in the U.S. and other countries
is a significant factor in the production and marketing of Embrex's products and
in its on-going research and development activities. Although the use of the
INOVOJECT(R) system is not subject to regulatory approval in the U.S., animal
health products being developed by Embrex must receive approval for marketing
from either the USDA or the Food and Drug Administration (the "FDA") and from
similar agencies in foreign countries where it has begun or contemplates doing
business. These countries may also require approval of the INOVOJECT(R) system.
Regulatory agencies require that products be tested in animals and demonstrate
appropriate levels of safety and efficacy. Generally, with respect to animal
health products, the USDA has regulatory authority over products which are
biological in origin or which stimulate or affect an animal's immune system, and
the FDA has authority over all other products. The time and cost of USDA
approvals are generally less than those for 

                                       8
<PAGE>

FDA approvals. FDA approval generally requires more extensive animal and
toxicology testing than USDA approvals and may take five or more years to
obtain, whereas USDA approvals generally require one to three years to obtain.
Embrex's VNF technology received USDA approval in January 1995 for IBD
applications post hatch and for in ovo use in January 1997. Of Embrex's products
currently under development, only the growth enhancing compounds and certain
gene therapy products (depending on the nature of the genetic material and the
response induced) are known to require FDA approval. Embrex believes all of its
other products under development will be subject only to USDA approval. Embrex's
existing products have received all necessary governmental approvals in the U.S.
Embrex's products also are subject to regulatory approval in other countries.

         Management believes that compliance with environmental regulations
currently has no material adverse effect on the Company's capital expenditures,
earnings or competitive position.

EMPLOYEES

         At December 31, 1996, Embrex employed 106 persons, 101 of whom were
full-time employees, an increase of 5 percent or 5 persons from the number of
employees at December 31, 1995.

SIGNIFICANT CUSTOMERS

         Tyson Foods, Inc. ("Tyson") and Perdue Farms, Inc. ("Perdue") accounted
for 33 and 11 percent of Embrex's consolidated 1996 revenues, respectively.
Based on the number of birds produced in 1996, Tyson and Perdue accounted for
approximately 22 and 8 percent of the broilers grown in the U.S., respectively.
In 1996, Tyson and Perdue were the only customers which represented greater than
10 percent of total revenues.

ITEM 2.  PROPERTIES

         Embrex leases its corporate headquarters and research and development
facilities, which occupy approximately 23,000 square feet and are located
adjacent to Research Triangle Park, North Carolina. Two-thirds of the space is
devoted to research and development. The lease is for a 10-year term expiring
March 31, 1997, with a 5 year renewal option at prevailing rates. Embrex pays an
annual rent of approximately $266,000. In December 1996, the Company exercised
its 5 year renewal option and renegotiated the annual rent. As a result, the
Company's annual rent, commencing April 1, 1997, decreases to $196,580, with
annual increases of approximately 3% thereafter. The lease will expire on March
31, 2002. Embrex paid rent totaling approximately $240,000 for its use of the
facility during 1996. Embrex is in the process of developing plans for a 
new 12,000 square foot testing facility near Embrex's Research 
Triangle Park headquarters. Embrex anticipates completing construction 
in 1997. Embrex has extended for twelve months, until 
May 10, 1998, its one-year lease agreement for
approximately 3,000 square feet of warehouse space in Springdale, Arkansas,
which is used to support the Embrex customer service function in the region. The
Company also leases offices of 650 square feet and warehouse space of 1,060
square feet in Great Dunmow, Essex, England and a 2,000 square foot office in
Dallas, Georgia to support field operations. Embrex also has access to
facilities at certain universities. The use of these facilities is important to
Embrex's ongoing research and development efforts. Embrex has agreements with
North Carolina State University providing access to facilities used for
incubating eggs and growing live birds and for research and testing purposes.
Embrex believes that suitable alternative facilities exist if the above
agreements are not renewed.

ITEM 3.  LEGAL PROCEEDINGS

         In September 1996, Embrex filed a patent infringement suit in the
United States District Court for the Eastern District of North Carolina against
Service Engineering Corporation, a Maryland corporation, and Edward G. Bounds,
Jr., a Maryland resident and officer of Service Engineering Corporation. The
suit alleged that each of the defendants' development of an in ovo injection
device, designed to compete with Embrex's patented INOVOJECT(R) injection
method, infringes at least one claim of the U.S. patent No. 4,458,630
exclusively licensed to Embrex for the in ovo injection of vaccines into an
avian embryo (the "Sharma Patent"). Further, Embrex claims that the defendants
have violated the terms of a Consent Judgment and Settlement Agreement entered
into with Embrex in November 1995 in which prior litigation was concluded with
Service Engineering and Bounds agreeing not to engage in future activities
violating the Sharma Patent. Embrex sought injunctive relief to prevent
infringement of the Sharma Patent as well as monetary damages. In

                                       9
<PAGE>

November 1996, Service Engineering Corporation and Edward G. Bounds responded to
Embrex's patent infringement suit by asserting various affirmative defenses and
denying the substantive allegations in Embrex's complaint.

         In November 1996, Embrex filed a patent infringement suit in the United
States District Court for the Eastern District of North Carolina against IGI,
Inc., a Delaware corporation. The suited alleged that IGI, through its
activities with Service Engineering Corporation and Edward G. Bounds, Jr., an
officer of Service Engineering Corporation, is engaging in activities that
constitute infringement of the Sharma Patent. Embrex sought injunctive relief to
prevent infringement of the Sharma Patent as well as monetary damages. In
January 1997, IGI, Inc. responded to Embrex's patent infringement suit by
asserting various affirmative defenses and denying the substantive allegations
in Embrex's complaint.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         No matters were submitted to a vote of security holders during the
fourth quarter of the fiscal year ended December 31, 1996.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

RESULTS OF OPERATIONS

         The following discussion and analysis should be read in conjunction
with the Company's financial statements and related notes appearing elsewhere in
this report.

         Consolidated net income for 1996 was $341,000 compared to net losses of
$4.5 million in 1995, on a restated basis, and $6.7 million in 1994. The Company
marked its first profitable year in 1996, which is attributable primarily to
continued growth in INOVOJECT(R) revenues. Earnings per share increased from net
losses of $1.12 in 1994 and $.71 in 1995, on a restated basis, to net income of
$.05 in 1996. For the year ended 1996, weighted average shares outstanding were
7.4 million, up from 6.3 and 6.0 million at year-end 1995 and 1994,
respectively. See "Liquidity and Capital Resources."


                                       11
<PAGE>

         Revenues

         Consolidated revenues in 1996 totaled $20.6 million, representing an
increase of 50% over 1995 revenues ($13.7 million) which was 199% over 
1994 revenues ($6.9 million). INOVOJECT(R) revenues totaled $19.3 million 
in 1996 compared to $12.8 million in 1995 and $5.9 million in 1994,
representing increases of 50% from 1995 to 1996, and 116% from 1994 to 1995.

         The 1996 revenues include INOVOJECT(R) lease fees derived from
multi-year contracts and paid trials in the U.S. and foreign countries, the sale
of INOVOJECT(R) systems to distributors, and the sale of one INOVOJECT(R) system
to a pharmaceutical company for use in the production of human influenza
vaccine. Embrex does not expect sales of INOVOJECT(R) systems for use in the
production of vaccines, if any, to be a significant source of future revenue. At
December 31, 1996, Embrex had over 250 INOVOJECT(R) systems installed and
operating under lease agreements worldwide, up from 235 systems at December 31,
1995, and 117 at December 31, 1994. Additionally, Embrex estimates that as of
December 31, 1996, it was vaccinating approximately 80% of the 7.7 billion
broiler birds grown in the U.S. in 1996, up from 66% in 1995, and 37% in 1994.

         Management anticipates further revenue growth in 1997 from existing
INOVOJECT(R) operations in the United States and Canada, new INOVOJECT(R) system
leases in other countries, and sales of BURSAPLEX(TM) product to poultry
producers. However, the rate at which the marketplace will accept the
INOVOJECT(R) technology outside the United States and Canada, the timing of
approvals of third-party vaccines for in ovo use outside the United States and
Canada, possible variability in U.S. hatchery bird production as a result of
recent high grain prices, and possible variability in the demand for U.S.
poultry and poultry products outside the U.S., will impact the pace of revenue
growth, if any, and the sustaining of profitability from the installation and
operational throughputs of INOVOJECT(R) systems.

         Sales of the Company's proprietary Viral Neutralizing Factor product
(VNF) for inclusion in Gumboro disease vaccines were the principal source of
product revenues, which generated $1.2 million, $817,000, and $952,000 in 1996,
1995, and 1994, respectively.

         Cost of Product Sales and INOVOJECT(R) REVENUES

         Cost of revenues as a percentage of revenues decreased from 62% and
80% of total revenues in 1995 and 1994, respectively, to 51% of total revenues
in 1996. The improvement in 1996 is primarily attributable to the fact that
revenues increased at a rate substantially in excess of the rate of change in
the cost of products.

         Operating Expenses

         Operating expenses totaled $8.3 million in 1996 compared to $7.4
million in 1995, and $7.8 million in 1994.

         General and administrative ("G&A") expenses were $3.7 million in 1996,
up 11% from $3.3 million in 1995, and 6% from $3.1 million in 1994. The 1996 
increase was largely due to increased legal expenses associated with the 
implementation of a shareholder rights plan in March 1996 and amendments to 
the Company's Articles of Incorporation approved at the annual meeting of 
shareholders in May 1996. The 1995 increase over 1994 was attributable to 
legal expenses incurred in connection with various patent infringement 
lawsuits filed, and subsequently settled, by the Company during 1995. 
See "Legal Proceedings."

         Sales and marketing expenses totaled $929,000 in 1996 compared to
$718,000 and $427,000 in 1995 and 1994, respectively. The increases in 1996 and
1995 resulted from stepped-up international activity, principally in Europe, as
well as general increases in the Company's sales and customer service functions
to support market expansion and field support of INOVOJECT(R) systems.

                                       12
<PAGE>

         Research and development ("R&D") expenses were $3.7 million in 1996
compared to $3.4 million in 1995 and $4.3 million in 1994. The increase in R&D
expense from 1995 to 1996 largely reflects an increase in outside contract
research, supplies consumption, and INOVOJECT(R) design and development
activity. The decrease in expense from 1994 to 1995 is principally attributable
to reductions in contract research, lower use of consumable supplies, and a
reduction in INOVOJECT(R) design and development activity. The Company continues
to manage its research and development effort to leverage its know-how, patent
position, market presence and expenditures.

         Other Income and Expense

         Interest income totaled $355,000, $389,000, and $297,000 in years 1996,
1995, and 1994, respectively. The 1996 decrease relative to 1995 resulted
principally from lower interest rates, while the increase in 1995 relative to
1994 was a function of higher cash balances.

         Interest expense totaled $1.6 million in 1996 compared to $2.7 million,
on a restated basis in 1995, and $579,000 in 1994. In all years, the amount of
expense is principally attributable to the Company's funding of its growing
installed base of INOVOJECT(R) systems with the use of capital lease financing
and in 1995 the issuance of convertible debentures. Additionally, interest
expense for 1995 has been restated to reflect a one-time charge associated with
recognizing $1,019,000 of interest expense attributable to the difference
between the market price of the Company's Common Stock and the conversion price
of the debentures issued in 1995. See "Liquidity and Capital Resources" and Note
11 to the Company's financial statements. Management expects to place a greater
emphasis and reliance on the use of internally generated funds to finance the
cost of additional INOVOJECT(R) systems in 1997.

         Effect of Inflation

         Management expects cost of product sales and INOVOJECT(R) revenues,
operating expenses and capital equipment costs to change in line with periodic
inflationary changes in price levels. Management also believes that the Company
will be able to offset the effect of price level changes by adjusting
selling/lease prices and effecting operating efficiencies. Consequently,
management does not expect changes in price levels to have any material adverse
affect on its results of operations.

LIQUIDITY AND CAPITAL RESOURCES

         At December 31, 1996, the Company's cash and short-term investment
balances totaled $9.9 million compared to $7.3 million and $4.6 million at
December 31, 1995 and 1994, respectively. Working capital increased from $5.9
million in 1995 to $7.6 million in 1996 primarily due to the exercise of
warrants as described below.

         During 1996, operating activities generated $4.1 million in cash,
including $626,000 million attributable to a net increase in working capital.
Within investing activities, INOVOJECT(R) and equipment purchases required $4.9
million, while the sale of short-term investments, provided an
offsetting $1.1 million. In addition, financing activities during 1996 generated
a net $3.3 million in cash reflecting $3.9 million from the issuance of equity
and debt securities offset by approximately $700,000 in net payments on 
capital lease obligations.

         To diversify its sources of external financing, in September 1996 the
Company obtained a $2.0 million line of credit from a bank in the United
Kingdom, which will be used to finance the construction of additional
INOVOJECT(R) systems for Europe, the Middle East and Africa. The line is secured
by compensating cash balances on deposit with the bank in an amount equal to the
funds loaned. The Company will receive interest on the deposited funds, and will
pay interest on the loaned funds at a rate of 1% in excess of the interest it
earns. The terms call for minimum drawdowns of $250,000, with repayment of each
drawdown over four years. The Company utilized $400,000 of this line in 1996.

         In November 1996, the holders of warrants to purchase Common Stock,
originally issued to the managing underwriter of the Company's initial public
offering, exercised such warrants for 638,805 shares at an aggregate exercise


                                       13
<PAGE>

price of $3,085,447. Also in November, warrants to purchase approximately 3.5
million shares of Common Stock at exercise prices ranging from $9.02 to $15.52
per share expired. After giving effect to these events, warrants to purchase a
total of 360,775 shares of Common Stock at prices ranging from $6.00 to $9.50,
subject to adjustment, remain outstanding. These outstanding warrants have
expiration dates ranging from July 29, 1998 through June 9, 2001.

         The Company had outstanding purchase commitments of approximately $3.5
million as of December 31, 1996 which were principally related to construction
of additional INOVOJECT(R) systems scheduled for delivery at various times
during 1997 as well as the production of BURSAPLEX(TM). See "Subsequent Events."

         Based on its current operations, management believes that its available
cash and short-term investments, together with cash flow from operations and
existing equipment financing lines, will be sufficient to meet its foreseeable
cash requirements.

SUBSEQUENT EVENTS

         On January 20, 1997, the Company received U.S. Department of
Agriculture (USDA) approval for in ovo use of the Company's viral neutralizing
factor-based vaccine for IBD in broiler chickens. The approval is specifically
for in ovo (as opposed to post-hatch) administration of the vaccine complex via
Embrex's INOVOJECT(R) systems.

         Trade-named BURSAPLEX(TM), this new vaccine (previously called
BDA-Blen) is a unique combination of an existing strain of IBD vaccine and
Embrex's patented Viral Neutralizing Factor (VNF) licensed from the University
of Arkansas. VNF has been shown to render a virulent infectious bursal disease
vaccine both safe and effective in broiler chickens, thus allowing its use at or
before hatch. Some of the health benefits of this new VNF/vaccine complex
include single-dose efficacy and effective early vaccination in broilers.
Infectious bursal disease weakens a chicken's immune system, resulting in poor
growth and the potential for contracting other diseases. The disease is
widespread in the United States, Northern Europe and Asia.

FORWARD-LOOKING STATEMENTS

Information set forth in this Annual Report on Form 10-K contains various
"forward looking statements" within the meeting of Section 27A of the Securities
Act of 1933 and Section 21E of the Securities Exchange Act of 1934, which
statements represent the Company's judgment concerning the future and are
subject to risks and uncertainties that could cause the Company's actual
operating results and financial position to differ materially. Such forward
looking statements can be identified by the use of forward looking terminology
such as "may," "will," "expect," "anticipate," "estimate," "believe," or
"continue," or the negative thereof or other variations thereof or comparable
terminology.

The Company cautions that any such forward looking statements are further
qualified by important factors that could cause the Company's actual operating
results to differ materially from those in the forward looking statements,
including without limitation the Company's dependence on certain customers; the
ability of the Company, its manufacturing and marketing partners and others to
obtain regulatory approval for products to be delivered in ovo, which are
dependent on a number of factors, including the results of trials, the
discretion of regulatory officials, and any potential changes in regulations;
the Company's ability to generate future cash flow from operations; continued
demand for the INOVOJECT (R) system; the Risk Factors described in Exhibit 99 to
this report; and other risks detailed from time to time in the Company's
Securities and Exchange Commission filings, including the Company's Forms 10-Q,
10-K, and 8-K.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA


                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Shareholders, Embrex, Inc.

We have audited the accompanying consolidated balance sheets of
Embrex, Inc. and subsidiaries as of December 31, 1996 and 1995, and
the related consolidated statements of operations, shareholders' equity
and cash flows for each of the three years in the period ended December
31, 1996. These consolidated financial statements are the responsibility
of the Company's management. Our responsibility is to express an opinion
on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial
position of Embrex, Inc. and subsidiaries at December 31, 1996 and 1995,
the consolidated results of their operations and their cash flows for
each of the three years in the period ended December 31, 1996, in
conformity with generally accepted accounting principles.

1. Significant Accounting Policies

Nature of Business

Embrex, Inc. has developed and commercialized the INOVOJECT(R) system, a
proprietary, automated, in-the-egg injection system which eliminates the need
for manual vaccination of newly hatched broiler chicks. Embrex also develops and
markets patented pharmaceutical and biological products to improve bird health,
reduce bird production costs and provide economic value to the global poultry
industry.

Principles of Consolidation

The consolidated financial statements include the accounts of Embrex, Inc.
and its wholly owned subsidiaries, Embrex Europe Limited and Embrex
Sales, Inc. (the "Company"). All significant intercompany transactions 
and accounts have been eliminated. Currently, foreign operations account 
for less than 10% of the Company's revenues.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.

Inventories

Items recorded as inventory are generally purchased from others and recorded at
the lower of cost or market using the average cost method. Materials and
supplies inventories include spare parts for the INOVOJECT(R) systems as well as
laboratory and general supplies. Product inventories are comprised of biological
compounds, principally the Company's viral neutralizing factor product (VNF).

INOVOJECT(R) Systems

INOVOJECT(R) systems are comprised of egg injection and related equipment
available for lease to customers. The equipment is recorded at the lower of cost
or estimated net realizable value. Depreciation is computed principally by using
accelerated methods over the estimated useful life of the equipment and
commences after construction is complete and the equipment is placed in service.

Equipment, Furniture and Fixtures

Equipment, furniture and fixtures are recorded at cost. Depreciation is computed
principally by using accelerated methods over the estimated useful lives of the
assets placed in service.

                                          19

Patents and Exclusive Licenses of Patentable Technology

Costs incurred to acquire exclusive licenses of U.S. patentable technology and
to apply for and obtain U.S. patents on internally developed technology are
capitalized and amortized over the period of the exclusive license agreements or
patents using the straight-line method.

Foreign Currency Translation

All assets and liabilities in the balance sheets of the Company's foreign
subsidiary, Embrex Europe Limited, are translated at year-end exchange rates
except shareholders' equity which is translated at historical rates. Revenues,
costs and expenses are recorded at average rates of exchange during the year.
Translation gains and losses are accumulated as a component of shareholders'
equity. Foreign currency transaction gains and losses are included in
determining net income.

Revenue Recognition

INOVOJECT(R) system fees are recognized based on eggs processed during the
period. Product sales are recognized when the products are shipped. Contract
research revenue is recognized on a straight-line basis over the term of the
contract. Revenue received, but not yet earned, is classified as deferred
revenue.

Research and Development Costs

Research and development costs, including costs incurred to complete contract
research, are charged to operations when incurred and are included in operating
expenses.

Income Taxes

Income tax expense includes U.S. and international income taxes. Certain items
of income and expense are not reported in tax returns and financial statements
in the same year. The tax effects of these differences are reported as deferred
income taxes. Tax credits are accounted for as a reduction of tax expense in the
year in which the credits reduce taxes payable.

Net Income (Loss) Per Share

Net income (loss) per share is computed using the weighted average number of
shares of Common Stock outstanding. Common equivalent shares from stock options
and warrants are excluded from the computation during periods of net loss
because their effect is antidilutive. For all periods presented, the difference
between primary and fully diluted net income per share is not significant.


Use of Estimates

                                       20
<PAGE>



The presentation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.

Actual results could differ from these estimates.

Principal Customers

Tyson Foods, Inc. ("Tyson") and Perdue Farms Inc. ("Perdue") accounted for 33
percent and 11 percent of consolidated 1996 revenues, respectively. Based on the
number of birds produced in 1996, Tyson and Perdue accounted for approximately
22 and 8 percent of the broilers grown in the U.S., respectively. In 1995, Tyson
and Perdue Farms, Inc. individually accounted for greater than 10 percent of
total revenues.

Sources of Supply

The Company has developed a strategic relationship with a single contract
manufacturer to fabricate its INOVOJECT(R) systems. While other machine
fabricators exist and have constructed limited numbers of INOVOJECT(R) systems,
a change in fabricators could cause a delay in manufacturing and a possible
delay in the timing of future INOVOJECT(R) installations and revenues from those
installations.

The Company has granted Select Laboratories, Inc. ("Select"), a division of
Rhone Merieux, exclusive rights to manufacture bursal disease vaccines
containing Embrex's proprietary VNF product for Embrex to market in the North
American, South American and Asian regions. Embrex has also granted Arthur
Webster Pty. Ltd. ("Webster") exclusive rights to manufacture bursal disease 
vaccines containing the Company's VNF product to be marketed in Europe, 
the Middle East and Africa. Additionally, the Company has two contract 
suppliers of its VNF product. The manufacture of the bursal disease vaccines 
being produced by Select and Webster and the Company's VNF product generally 
must be performed in licensed facilities and/or under regulatory approved
methods. Although there are other manufacturers who are capable of 
manufacturing bursal disease products and producing products such as VNF, a 
change of suppliers could adversely effect the Company's future operating 
results due to the time it would take a new supplier to obtain regulatory 
approval of its production process and/or manufacturing facilities. The
Company seeks to minimize this exposure through multi-year supply agreements 
and the maintenance of adequate inventories.

Long-Lived Assets

The Company adopted Financial Accounting Standards Board ("FASB") Statement No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of" ("FASB 121") in the first quarter of 1996. The
adoption for FASB 121 had no material effect on the financial statements in
1996.

Reclassification

Certain 1995 and 1994 amounts in the accompanying financial statements have been
reclassified to conform to the 1996 presentation. These reclassifications had no
effect on previously reported net loss or shareholders' equity.





2. Short-Term Investments

Management determines the appropriate classification of its investments in debt
securities at the time of purchase and reevaluates such determination at each
balance sheet date. Debt securities for which the Company has both the intent
and ability to hold to maturity are classified as held to maturity. These
securities are carried at amortized cost. At December 31, 1996, the Company had
no investments that qualified as trading or available for sale.

 At December 31, 1996, the Company's investments in debt securities were
classified as cash and cash equivalents and short-term investments. The Company
maintains cash and cash equivalents and short-term investments principally of
United States treasury securities and commercial paper with a maturity date less
than twelve months with various financial institutions. The Company performs
periodic evaluations of the relative credit standing of those financial
institutions that are considered in the Company's investment strategy which is
designed to limit exposure to any one institution.

The following is a summary of short-term investments by balance sheet
classification at December 31:

The Company's short-term investment balances are maintained in accounts at
various financial institutions. In connection with the secured line of
credit, the Company has deposited $417,000 as a compensating cash balance
with the lender.

3. Leases

At December 31, 1996 and 1995, the Company had assets totaling $13.9 million and
$13.1 million, respectively, financed by capital lease agreements which expire
through October 2000. Accumulated depreciation and amortization includes $8.2
million and $5.1 million of amortization related to these assets at December 31,
1996 and 1995, respectively. Amortization of assets financed by capital leases
is included with depreciation expense. As of December 31, 1996, the Company has
used $9.2 million ($2.1 million in 1996 and $7.1 million in 1995) of the $11.2
million capital lease financing closed in 1995 to fund construction of
INOVOJECT(R) systems principally under contract with North American customers in
the United States. At December 31, 1996, the Company had available $2.0 million
of aggregate unutilized capital financing capacity for use in the construction
of INOVOJECT(R) systems.

The Company leases its principal facilities under an operating lease extending
through March 2002. The company has the option to cancel the operating lease
agreement with the payment of a $180,000 penalty. Total rent expense was
$334,000, $426,000, and $307,000 for the years ended December 31, 1996, 1995,
and 1994, respectively.

At December 31, 1996, the Company's minimum future commitments under capital and
operating leases were as follows:

4. Long-Term Debt

 On May 1, 1995, the Company closed on a private placement offering of
convertible debentures ("the debentures") resulting in net proceeds to the
Company of $5.4 million (as adjusted for the August 1995 rescission of the
issuance of $225,000 of the debentures). The debentures are payable on May 1,
1997. Through June 13, 1995, the holders of the debentures were entitled to
convert the debentures into Common Stock of the Company at a conversion price
equal to the average market price at the time of issuance. Commencing on June
14, 1995, the holders of the debentures are entitled to convert the debentures
into Common Stock of the Company at a conversion price of the lesser of the
market price at the time of issuance ($5.00 per share) or 85 percent of the
average closing bid price of the Company's Common Stock for the five trading
days ending on the conversion date. The debentures accrue interest, payable at
maturity, at a rate of 8 percent per annum. The accrued interest is convertible
into Common Stock of the Company at the same conversion price as the debenture
principal. The Company has the right to demand conversion of the debentures and
any accrued interest after April 30, 1996. Additionally, at any time, the
Company has the right to redeem the debentures for cash equal to the closing bid
of the Company's Common Stock at the date of redemption multiplied by the
underlying shares into which the debentures would have been convertible. In
conjunction with this offering, the Company incurred issuance costs totaling
$540,000 and recorded $1.0 million of interest expense related to the 15%
discount from market upon conversion (See Note 11). The issuance costs are being
amortized as a component of interest expense over the term of the debentures.

In 1995, $3.0 million of the debentures' principal and related discount was
converted into 517,910 shares of Common Stock, net of unamortized debt issuance
costs totaling $215,000. During 1996, an additional $3.3 million debentures and
related discount, along with $258,000 of accrued interest were converted into
612,061 shares of Common Stock, net of unamortized debt issuance costs totaling
$111,000.

As part of its compensation for the sale of the convertible debentures, the
Company's placement agent received a 6.5 percent commission, which is included
in the $540,000 total issuance costs, and warrants to purchase 96,000 shares of
Common Stock at a price of $6.00 per share. The estimated value of these
warrants, $150,600, has been recorded as additional paid-in capital, while their
cost has been included within the $540,000 total issuance costs discussed above.

On May 29, 1991, the Company issued a four-year convertible term note (the
"note") to American Cyanamid Company, now a subsidiary of American Home Products
Corporation, in exchange for $1.2 million. During May 1995, at the election of
American Cyanamid, the

                                      24

<PAGE>




note was converted into 320,000 shares of Common Stock of the Company. 
Contemporaneous with the conversion, the Company paid to American Cyanamid 
$160,000 of accrued interest due on the note.

5. Shareholders' Equity

On May 16, 1996, the Company's shareholders approved an increase in the number
of authorized shares of Common Stock from 15,000,000 to 30,000,000 shares and an
increase in the amount of authorized Preferred Stock from 20,000 to 15,000,000
shares. In addition, the Company changed the par value of the Common Stock and
Series A Participating Preferred Stock from no par value to par value stock,
with a par value of $.01 per share.

At December 31, 1996, the Company had reserved a total of 2,006,970 shares of
its Common Stock for future issuance as follows:

For conversion of debentures                            96,492

6. Stock Option Plans

The Company's stock option plans provide for option grants designated as either
nonqualified or incentive stock options. The options generally vest over a
four-year period and expire ten years from the date of grant. In general, the
exercise price of stock options is the closing price of the Company's Common
Stock on the date of grant.

Most U.S. employees and certain employees outside the U.S. are eligible to
receive a grant of stock options periodically with the number of shares
generally determined by the employee's salary grade and performance level. In
addition, certain management and professional level employees may receive a
stock option grant upon hire. Non- employee directors of the Company receive
annual grants of stock options in amounts specified in the applicable plan.

</TABLE>

At December 31, 1996, options to purchase 534,188 shares of Common Stock were
exercisable at prices ranging from $2.00 to $8.375 per share.

The Company has elected to follow Accounting Principles Board Option No. 25,
"Accounting for Stock Issued to Employees" (APB 25) and related Interpretations
in accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under FASB Statement No. 123,
"Accounting for Stock-Based Compensation," requires use of option valuation 
models that were not developed for use in valuing employee stock options. Under 
APB 25, because the exercise price of the Company's employee stock options 
equals the market price of the underlying stock on the date of grant, no 
compensation expense is recognized.

                                        27
<PAGE>



The Company's 1996 Amendment to its 1993 Incentive Stock Option Plan increases
the authorized grant of options to company personnel from 500,000 shares of
common stock up to 1.2 million shares. All options granted have 10 year 
terms and vest and become fully exercisable at the end of 4 years of 
continued employment.

Proforma information regarding net loss and loss per share is required by SFAS
123, and has been determined as if the Company accounted for its employee stock
options granted subsequent to December 31, 1994 under the fair value method of
SFAS 123. The fair value for these options was estimated at the date of grant
using a Black- Scholes option pricing model with the following weighted average
assumptions for 1996 and 1995:
                                     1996                          1995
Risk free interest rate              6.42                          6.67
Dividends                             --                            --
Volatility factor                    .421                          .421

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options which have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions including the expected stock price volatility. Because
changes in the subjective input assumptions can materially affect the fair value
estimate, in management's opinion, the existing models do not necessarily
provide a reliable single measure of the fair value of its employee stock
options.

For purposes of proforma disclosures, the estimated fair value of the options is
amortized to expense over the options' vesting period. The Company's pro forma
information follows:

                                                        December 31
                                             1996                    1995
Pro forma net income (loss)                 $51,513                $(4,574,000)
Pro forma income (loss) per share           $  .007                $      (.72)



Because SFAS 123 is applicable only to options granted subsequent to December
31, 1994, its proforma effect will not be fully reflected until 1997.

Exercise prices for options outstanding as of December 31, 1996
ranged from $5.875 to $8.75.


                                 28

The weighted average remaining contractual life of those options is 8.21
years. The weighted average exercisable price of outstanding options at December
31, 1996 is $6.30.

7. Employee Stock Purchase Plan

The Company has an Employee Stock Purchase Plan (the "Purchase Plan") to provide
its employees with an additional opportunity to share in the ownership of the
Company. Under terms of the Purchase Plan, all regular full-time employees of
the Company may make voluntary payroll contributions thereby enabling them to
purchase Common Stock at a price to be determined by the Compensation Committee
of the Board, but not less than 85 percent of the lower of the fair market value
as of the beginning or end of the twelve-month offering period. Contributions 
are limited to 20 percent of an employee's compensation. Up to 100,000 shares of
Common Stock may be issued under the Purchase Plan.

Under the Purchase Plan, during 1996, 1995 and 1994, 11,028, 17,041 and 7,556
shares of Common Stock, respectively, were purchased.

liabilities. Significant components of the Company's deferred tax assets are as

During 1996 and 1995, the valuation allowance (decreased) increased by
($255,000) and $1,112,000, respectively.



At December 31, 1996, the Company had net operating loss carry forwards for
federal income tax purposes of approximately $34 million which are available to
offset future taxable income. These net operating loss carry forwards expire
during the years 2000 through 2010. As a result of the changes in ownership
percentages which occurred with the 1991 Initial Public Offering (IPO), the
future utilization of the net operating loss carry forwards incurred prior to
the 1991 IPO is limited to approximately $2.1 million per year. Any loss
carryforward amounts exceeding the limitation can be carried forward to future
years within the carryforward period. The net operating loss carry forwards
incurred

subsequent to the 1991 IPO are not subject to these change in ownership 
limitations.



In addition, the Company has Research and Experimental Tax Credit Carry forwards
totaling approximately $1.6 million which are available to offset future federal
income taxes. These credits expire during the years 2000 through 2012.

11.      Restatement


At the annual meeting of the American Institute of Certified Public Accountants
(AICPA) in January 1997 and at the March 1997 staff meeting of the Emerging
Issues Task Force of the Financial Accounting Standards Board (FASB), the
Securities and Exchange Commission staff stated that a charge to income is
appropriate in situations where a registrant has issued debt securities
convertible to Common Stock at the lower of a conversion rate fixed at issuance
or a fixed discount to the Common Stock's market price at the date of
conversion.

In accordance with the SEC's position, the Company has restated its
1995 financial statements to record additional interest expense of
$1.1 million related to the conversion feature at a 15% discount included in
the 1995 debentures (see Note 4). The restatement resulted in an increase 
of $1.0 million in the previously reported 1995 net loss and an increase in 
1995 net loss per share from $.55 per share to $.71 per share. In addition, 
at December 31, 1995, long-term debt was increased by $569,000 and shareholders 
equity was decreased by $569,000 to reflect the conversion discount related to 
outstanding debentures that had not been converted.

                         Report of Independent Auditors


The Board of Directors
Embrex, Inc.


We have audited the accompanying statements of net assets available for plan
benefits of Embrex, Inc. Employee Stock Purchase Plan as of December 31, 1996
and 1995, and the related statement of changes in net assets available for plan
benefits for each of the three years in the period ended December
31, 1996. 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 generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for plan benefits of Embrex,
Inc. Employee Stock Purchase Plan at December 31, 1996 and 1995, and the changes
in net assets available for plan benefits for each of the three years in the
period ended December 31, 1996 in conformity with generally accepted 
accounting principles.

                    EMBREX, INC. EMPLOYEE STOCK PURCHASE PLAN
                          NOTES TO FINANCIAL STATEMENTS

                                December 31, 1996



NOTE 1 - BASIS OF PRESENTATION

The accompanying financial statements of the Embrex, Inc. Employee Stock
Purchase Plan ("the Plan") have been prepared on the accrual basis.

NOTE 2 - PLAN DESCRIPTION AND SUMMARY OF SIGNIFICANT PLAN PROVISIONS

The Board of Directors of Embrex, Inc. ("the Company") adopted the Plan on
January 28, 1993, and the Plan was approved by shareholders of the Company at
the Annual Meeting of Shareholders on May 20, 1993. The Plan became effective as
of June 1, 1993.

The purpose of this Plan is to provide the Company's employees with an
additional opportunity to share in the ownership of the Company. Under terms of
the Plan, all regular full-time employees of the Company may make voluntary
payroll contributions thereby enabling them to purchase Common Stock at a price
to be determined by the Compensation Committee of the Board, but not less than
85 percent of the lower of the fair market values as of the beginning or end of
the twelve month offering period.

Contributions are limited to 20 percent of an employee's compensation, and the
aggregate number of shares of Common Stock which may be purchased in total by
all Plan participants may not exceed 100,000 shares.

Contributions to the Plan are maintained in a non-interest bearing account until
such time as the participant exercises the option to purchase shares of Common
Stock from his or her available contributions, or withdraws from the account.
All amounts representing net Plan assets are considered general assets of the
Company and may be subject to the claims of creditors.

In addition to contributions, plan activity consists of voluntary purchases of
shares of Common Stock and withdrawals from participation in the Plan.
Participants may purchase whole shares of Common Stock during a Purchase Period
(generally a twelve month period ending each June 30th). A participant may
withdraw from the Plan and cease making contributions at any time.

The Plan is not subject to the provisions of the Employee Retirement Income
Security Act of 1974 ("ERISA") and is not qualified under Section 401(a) of the
Internal Revenue Code of 1986, as amended which relates to qualification of
certain pension, profit-sharing and stock bonus plans.

All costs to administer the Plan are paid by the Company.

                AMENDED AND RESTATED EMPLOYEE STOCK PURCHASE PLAN


                             ARTICLE I. INTRODUCTION

         Section 1.01 Background. On January 28, 1993, the Board of Directors of
Embrex, Inc. (the "Company") adopted the Employee Stock Purchase Plan and the
shareholders of the Company approved such plan at the Annual Meeting of
Shareholders on May 20, 1993. On November 21, 1996, the Board of Directors
amended such plan by adopting this Amended and Restated Employee Stock Purchase
Plan (hereinafter referred to as the "Plan").

         Section 1.02 Purpose. The purpose of the Plan is to provide the
employees of the Company and certain related corporations with an opportunity to
share in the ownership of the Company by providing them a convenient means for
regular and systematic purchases of the Company's Common Stock and, thus, to
develop a stronger incentive to work for the continued success of the Company.

         Section 1.03  Effective Date.  The Plan will become effective on and as
of June 1, 1993.

         Section 1.04 Rules of Interpretation. It is intended that the Plan be
an "employee stock purchase plan" as defined in Section 423(b) of the Internal
Revenue Code of 1986, as amended (the "Code"), and Treasury Regulations
promulgated thereunder. Accordingly, the Plan will be interpreted and
administered in a manner consistent therewith. All Participants in the Plan will
have the same rights and privileges consistent with the provisions of the Plan.

Company by any "person" (as defined in Section 13(d) of the Exchange Act) other
than the Company, by means of a tender offer, exchange offer or otherwise; and
(ii) the date five (5) business days after the date of public announcement of
the acquisition of beneficial ownership (as so defined) of more than twenty-five
percent (25%) but not more than fifty percent (50%) of the outstanding voting
stock of the Company by any person (as so defined) other than the Company, by
means of a tender offer, exchange offer or otherwise if, during such five (5)
business day period, the Board or the Committee (as defined in Section 1.05(d)
below) has not, by resolution duly adopted, elected that such acquisition not
give rise to an Acquisition Date. In any such resolution, the Board or Committee
may elect that any continued acquisition or acquisitions by the same person (as
so defined) which would otherwise trigger an Acquisition Date under clause (ii)
above shall also not give rise to an Acquisition Date.

         (c)      "Affiliate"  means any parent or subsidiary  corporation  of

exchange.

earlier of the next June 30 or the next Acceleration Date.

         (n) "Regular Full-Time Employee" means an employee of the Company or a

                    ARTICLE II. ELIGIBILITY AND PARTICIPATION

         Section 2.01 Eligible Employees. All Regular Full-Time Employees as
defined in Section 1.05(n) shall be eligible to participate in the Plan
beginning on the first day after such person becomes a Regular Full-Time
Employee. Subject to the provisions of Article VI, each such employee will
continue to be eligible to participate in the Plan so long as he or she remains
a Regular Full-Time Employee.

         Section 2.02 Election to Participate. An eligible Regular Full-Time
Employee may elect to participate in the Plan by filing with his or her Employer
a form provided by such Employer authorizing regular payroll deductions from
Current Compensation. Participation and payroll deductions shall begin on the

the Plan or ceases to be eligible to participate in the Plan.

         Section 2.03 Commencement of Participation. The initial Enrollment Date
shall be June 1, 1993, for all eligible Regular Full-Time Employees who file an

which they become eligible to participate shall be the first day of the next pay
period following their election, and the Enrollment Date for all others shall be

         Section 2.04 Limits on Stock Purchase. No employee shall be granted any
right to purchase hereunder if such employee, immediately after a right to
purchase is granted, would own, directly or indirectly, stock possessing five
percent (5%) or more of the total combined voting power or value of all classes

Plan, the rules of Section 424(d) of the Code shall apply in determining the

                                       3

<PAGE>




stock which the Participant may purchase under outstanding options shall be 
treated as stock owned by the Participant.

         Section 2.05 Voluntary Participation. Participation in the Plan on the
part of the Participant is voluntary and such participation is not a condition
of employment, nor does participation in the Plan entitle a Participant to be
retained as an employee.


                       ARTICLE III. PAYROLL DEDUCTIONS AND
                             STOCK PURCHASE ACCOUNT

         Section 3.01 Deduction from Pay. The form described in Section 2.02
will permit a Participant to elect payroll deductions of any whole percentage
from one percent (1%) through twenty percent (20%) of Current Compensation for
each pay period. The Participant may reduce or increase future payroll
deductions (within the foregoing limitations) by filing with such Participant's
Employer a form provided by such Employer for such purpose. The effective date
of any reduction in future payroll deductions will be the first day of the next
succeeding pay period. The effective date of any increase in future payroll
deductions will be the first day of the next succeeding Purchase Period. Also,
the Participant may cease making payroll deductions at any time, as provided in
Section 6.01.

         Section 3.02 Credit to Account. Payroll deductions will be credited to
the Participant's Stock Purchase Account on each payday.

         Section 3.03 Interest. No interest will be paid upon payroll deductions
or on any amount credited to, or on deposit in, a Participant's Stock Purchase
Account.

         Section 3.04 Nature of Account. The Stock Purchase Account is
established solely for accounting purposes, and all amounts credited to the
Stock Purchase Account will remain part of the general assets of the Company or
the Participating Affiliate (as the case may be).

         Section 3.05 No Additional Contributions. A Participant may not make
any payment into the Stock Purchase Account other than the payroll deductions
made pursuant to the Plan.


                      ARTICLE IV. RIGHT TO PURCHASE SHARES

         Section 4.01 Number of Shares. Subject to the provisions of Section
5.01 herein, each Participant will have the right to purchase at any time, at
the price specified in Section 4.02, any number of whole shares of Stock that
can be purchased with the entire credit balance in the Participant's Stock
Purchase Account; provided, however, that on no occasion may any one Participant
purchase (a) more than Five Thousand (5,000) shares of Stock under the Plan
during any Purchase Period or (b) more than Twenty-five Thousand Dollars
($25,000) in Fair Market Value (determined at the beginning of each Purchase
Period) of Stock under the Plan and all other employee stock purchase plans (if
any) of the Company and the Affiliates during any calendar year. If the
purchases for all Participants would otherwise cause the aggregate number of
shares of Stock to be sold under the Plan to exceed the number specified in
Section 10.03, however, each Participant shall be allocated a pro rata portion
of the Stock to be sold.

                                       4
<PAGE>


         Section 4.02 Purchase Price. The percentage of Fair Market Value to be
used in determining the purchase price during each Purchase Period shall be
established by the Committee at least thirty (30) days prior to the commencement
of each such Purchase Period. In no event shall the purchase price be less than
the lesser of (a) eighty-five percent (85%) of the Fair Market Value of the
Stock on the first business day of the Purchase Period or (b) eighty-five
percent (85%) of the Fair Market Value of the Stock on the date of exercise of
the right to purchase by the Participant, in each case rounded up to the next
higher full cent.


                          ARTICLE V. EXERCISE OF RIGHT

         Section 5.01 Purchase of Stock. A Participant may purchase shares of
Stock at any time by filing written notice with his or her Employer, on a form
provided for this purpose by the Employer, designating the portion of the credit
balance in such Participant's Stock Purchase Account to be used for such
purchase; provided, however, that the number of shares purchasable upon any
exercise of this right shall be no less than ten (10) whole shares and shall be
no greater than the largest number of whole shares of Stock purchasable with
such credit balance (subject to the additional limitations of Section 4.01);
and, provided, further, that each Participant may exercise this right of
purchase on no more than four (4) occasions during any Purchase Period.

         Section 5.02 Stock Transfer Restrictions. This Plan is intended to
satisfy the requirements of Section 423 of the Code. A participant will not
obtain the benefits of this provision if such Participant disposes of Stock
acquired pursuant to the Plan within two (2) years from the first day of the
Purchase Period or within one (1) year from the date the Stock is purchased by
the Participant.

         Section 5.03 Cash Distributions. Any amount remaining in a
Participant's Stock Purchase Account after the last business day of a Purchase
Period will be paid to the Participant in cash within thirty (30) days after the
end of the Purchase Period.

         Section 5.04 Notice of Acceleration Date. The Company shall use its
best efforts to notify each Participant in writing at least ten (10) days prior
to any Acceleration Date that the then current Purchase Period will end on such
Acceleration Date.


                        ARTICLE VI. WITHDRAWAL FROM PLAN

         Section 6.01 Voluntary Withdrawal. A Participant may, at any time,
withdraw from the Plan and cease making payroll deductions by filing with such
Participant's Employer a form provided for this purpose. In such event, the
entire credit balance in the Participant's Stock Purchase Account will be paid
to the Participant in cash within thirty (30) days. A Participant who withdraws
from the Plan will not be eligible to reenter the Plan until the beginning of
the next Purchase Period.

         Section 6.02 Death. Participation in the Plan will cease on the date of
the Participant's death, and the entire credit balance in the Stock Purchase
Account will be paid to the Participant's estate in cash within thirty (30)
days. Each Participant, however, may designate one or more beneficiaries who,
upon death, are to receive the amount that otherwise would have been paid to the
Participant's estate 

                                       5

and may change or revoke any such designation from time to time. No such 
designation, change or revocation will be effective unless made by the 
Participant in writing and filed with the Participant's Employer during the
Participant's lifetime. Unless the Participant has otherwise specified in the
beneficiary designation, the beneficiary or beneficiaries so designated will
become fixed as of death so that, if a beneficiary survives the Participant but
dies before the receipt of the payment due such beneficiary, the payment will be
made to such beneficiary's estate.

         Section 6.03 Termination of Employment. Participation in the Plan also
will cease on the date the Participant ceases to be a Regular Full-Time Employee
for any reason other than death. In such event, the entire credit balance in the
Participant's Stock Purchase Account will be paid to the Participant in cash
within thirty (30) days. For purposes of this Section, an unpaid leave of
absence without the prior written approval of the Committee will be deemed a
termination of employment but a paid leave of absence or an unpaid leave of
absence which has been approved by the Committee or is required by law or
regulation will not be deemed a termination of employment as a Regular Full-Time
Employee.


                         ARTICLE VII. NONTRANSFERABILITY

         Section 7.01 Nontransferable Right to Purchase. The right to purchase
Stock hereunder may not be assigned, transferred, pledged or hypothecated
(whether by operation of law or otherwise) other than by will or the laws of
descent and distribution, and must be exercisable during the Participant's
lifetime only by the Participant. The right to purchase Stock hereunder will not
be subject to execution, attachment or similar process. Except as provided
herein, any attempted assignment, transfer, pledge, hypothecation or other
disposition or levy of attachment or similar process upon the right to purchase
will be null and void and without effect.

         Section 7.02 Nontransferable Account. The amounts credited to a Stock
Purchase Account may not be assigned, transferred, pledged or hypothecated in
any way, and any attempted assignment, transfer, pledge, hypothecation or other
disposition of such amounts will be null and void and without effect.


                        ARTICLE VIII. STOCK CERTIFICATES

         Section 8.01 Delivery. Within thirty (30) days after a Participant
exercises his or her right to purchase pursuant to Section 5.01, the Company
will cause to be delivered to the Participant a certificate representing the
Stock purchased.

         Section 8.02 Securities Laws. The Company shall not be required to
issue or deliver any certificate representing Stock prior to registration under
the Securities Act of 1933, as amended, or registration or qualification under
any state law if such registration is required. The Company will use its best
efforts to accomplish such registration (if and to the extent required) within a
reasonable time following exercise of the right to purchase, and delivery of
certificates may be deferred until registration is accomplished.

         Section 8.03 Completion of Purchase. A Participant will have no
interest in the Stock purchased until a certificate representing the same is
issued.

         Section 8.04 Form of Ownership. The certificates representing Stock
issued under the Plan will be registered in the name of the Participant or
jointly in the name of the Participant and another person, as the Participant
may direct on a form provided by the Participant's Employer.


                          ARTICLE IX. AMENDMENT OF AND
                               TERMINATION OF PLAN

         Section 9.01 Powers of Board. The Board of Directors of the Company may
at any time amend or terminate the Plan, except that no amendment will be made
without prior approval of the shareholders which would (a) authorize an increase
in the number of shares of Stock which may be purchased under the Plan, except
as provided in Section 11.01, (b) permit the issuance of Stock before payment
therefor in full, (c) increase the rate of payroll deductions above twenty

                            ARTICLE X. ADMINISTRATION

         Section 10.01 Appointment of Committee. The Board of Directors of the
Company shall appoint a Committee to administer the Plan consisting of three or
more persons (who may, but need not be, directors of the Company or of a
Participating Affiliate). The Board will determine the size of the Committee
from time to time and will have the power to remove and replace the members
thereof.

         Section 10.02 Powers of Committee. Subject to the provisions of the
Plan, the Committee will have full authority to administer the Plan, including
authority to interpret and construe any provision of the Plan, to establish

the Plan as it may deem appropriate. Decisions of the Committee will be final
and binding on all parties who have an interest in the Plan.

         Section 10.03 Stock to be Sold. The Stock to be issued and sold under
the Plan shall be authorized but unissued Stock. Except as provided in Section
11.01, the aggregate number of shares of Stock to be sold under the Plan will

1, 1990 (the "Agreement");
         WHEREAS, Employee continues to be employed by Employer; and WHEREAS,
         the parties both desire to amend the prior Employment

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties agree to amend their
prior Agreement as follows:
         The Agreement is hereby amended by deleting Paragraph 12, Termination
and Liquidated Damages and inserting in lieu thereof the following:
         12.      SEVERANCE.  If Employer terminates Employee's employment

                      CHANGE IN CONTROL SEVERANCE AGREEMENT

         THIS CHANGE IN CONTROL SEVERANCE AGREEMENT ("Agreement"), is made and
entered into this 21st day of May, 1996 by and between Embrex, Inc. ("Company"),
a North Carolina corporation, and Randall L. Marcuson ("Employee").
         WHEREAS, the Board of Directors ("Board") of the Company considers the
maintenance of a vital management group to be essential in protecting and 
enhancing the best interests of the Company and its shareholders;
          WHEREAS, the Board recognizes that the possibility of a Change in
Control (as hereinafter defined) exists and that the threat of or the occurrence
of a Change in Control can result in significant distractions of its key
management personnel because of the uncertainties inherent in such a situation;
         WHEREAS, the Board has determined that it is in the best interest of
the Company and its shareholders to ensure the Employee's continued dedication
and efforts on behalf of the Company; and
         WHEREAS, in order to induce the Employee to remain in the employ of the
Company, particularly in the event of a threat of or the occurrence of a Change
in Control and to dispel any concerns that the Employee may have about taking an
active part in the defense against an inappropriate attempt to bring about a
Change in Control of the Company, the Company desires to enter into this
Agreement with the Employee to provide the Employee with certain payments and
benefits in the event that his employment with the Company is terminated as a
result of, or in connection with, a Change in Control.
         NOW, THEREFORE, in consideration of the mutual agreements herein set
forth, the legal sufficiency and adequacy of which are hereby acknowledged, the
parties agree as follows:

                                        1

<PAGE>



         1. Employment. Employee acknowledges that he is employed with the
Company pursuant to an Employment Agreement dated November 15, 1989 and hereby
agrees that to the extent any provision of this Agreement should be contrary to
any provision of the Employment Agreement, the terms of this Agreement shall
control.
         2.       Definitions.  For purposes of this Agreement, the following 
terms have the meanings indicated:
                  (A) "Acquiring Person" shall mean any Person (as such term is
hereinafter defined) who or which, together with all Affiliates (as such term is
hereinafter defined) and Associates (as such term is hereinafter defined) of
such Person, shall be the Beneficial Owner (as such term is hereinafter defined)
of thirty-three percent (33%) or more of the shares of Common Stock then
outstanding, but shall not include (i) the Company, (ii) any Subsidiary of the
Company, (iii) any employee benefit plan or employee stock plan of the Company
or of any Subsidiary of the Company, (iv) any dividend reinvestment plan of the
Company, or (v) any Person or entity organized, appointed, or established by the
Company for or pursuant to the terms of such plan. Notwithstanding the
foregoing, no Person shall become an "Acquiring Person" as the result of an
acquisition of Common Stock by the Company which, by reducing the number of
shares outstanding, increases the proportionate number of shares beneficially
owned by such Person to thirty-three percent (33%) or more of the Common Stock
of the Company then outstanding; provided, however, that if a Person shall
become the Beneficial Owner of thirty-three (33%) or more of the Common Stock of
the Company, then outstanding by reason of such an acquisition and shall, after
such acquisition, become the Beneficial Owner of any additional shares of Common
Stock, then such Person shall be deemed to be an "Acquiring Person." In
addition, notwithstanding the foregoing, if the Board of Directors of the
Company determines in good faith that a Person who would otherwise be an
"Acquiring

                                        2

<PAGE>



Person," as defined pursuant to the foregoing provisions of this Paragraph (A),
has become such inadvertently, and such Person divests as promptly as
practicable a sufficient number of shares of Common Stock so that such Person
would no longer be an "Acquiring Person" as defined pursuant to the foregoing
provisions of this Paragraph (A), then such Person shall not be deemed to be an
"Acquiring Person" for any purposes of this Agreement.
                  (B) "Affiliate" and "Associate" shall have the respective
meanings ascribed to such terms in Rule 12b-2 of the General Rules and
Regulations under the Securities Exchange Act of 1934, as amended (the "Exchange
Act").
                  (C) A Person shall be deemed the "Beneficial Owner" of and
shall be deemed to "beneficially own," any securities:
                           (i) which such Person or any of such Person's
                  Affiliates or Associates, directly or indirectly, has the
                  right or obligation to acquire (whether such right is
                  exercisable immediately or only after the passage of time)
                  pursuant to any agreement, arrangement or understanding
                  (whether or not in writing) or upon the exercise of conversion
                  rights, exchange rights, rights, warrants or options, or
                  otherwise; provided, however, that a Person shall not be
                  deemed the "Beneficial Owner" of, or to "beneficially own,"
                  (a) securities tendered pursuant to a tender or exchange offer
                  made by such Person or any of such Person's Affiliates or
                  Associates until such tendered securities are accepted for
                  purchase or exchange, or (b) at any time prior to the
                  occurrence of a Triggering Event, securities issuable upon
                  exercise of the Rights ("Triggering Event" and "Rights" shall
                  have the respective meanings ascribed to such terms as set
                  forth in the Rights Agreement between Embrex, Inc. and Branch
                  Banking & Trust Company as Rights Agent, dated as of March 21,
                  1996 and as in effect on the date

                  occurrence of a Triggering Event, securities issuable upon
                  exercise of Rights which were acquired by such Person or any
                  of such Person's Affiliates or Associates prior to the
                  Distribution Date (as defined in the Rights Agreement) or
                  pursuant to Section 3(a) or Section 22 of the Rights Agreement
                  (the "Original Rights") or pursuant to Section 11(i) of the
                  Rights Agreement in connection with an adjustment made with
                  respect to any Original Rights;
                           (ii) which such Person or any of such Person's
                  Affiliates or Associates, directly or indirectly, has the
                  right to vote or dispose of or has "beneficial ownership" of
                  (as determined pursuant to Rule 13d-3 of the General Rules and
                  Regulations under the Exchange Act and any successor provision
                  thereof), including pursuant to any agreement, arrangement or
                  understanding, whether or not in writing; provided, however,
                  that a Person shall not be deemed the "Beneficial Owner" of,

                  (ii) as a result of an agreement, arrangement or understanding
                  to vote such security if such agreement, arrangement or
                  understanding: (a) arises solely from a revocable proxy given
                  in response to a public proxy or consent solicitation made
                  pursuant to, and in accordance with, the applicable provisions
                  of the General Rules and Regulations under the Exchange Act,
                  and (b) is not also then reportable by such Person on Schedule
                  13D under the Exchange Act (or any comparable or successor
                  report); or
                           (iii) which are beneficially owned, directly or
                  indirectly, by any other Person (or any Affiliate or Associate
                  thereof) with which such Person (or any of such Person's
                  Affiliates or Associates) has any agreement, arrangement or

                  voting (except pursuant to a revocable proxy as described in
                  the provision to subparagraph (ii) of this paragraph (C)) or

                  perform substantially his duties with the Company (other than
                  any such failure resulting from his Disability) for a
                  significant period of time, after a demand for substantial
                  performance is delivered to Employee by the Board or a
                  committee thereof, which specifically identifies the manner in
                  which the Board believes that Employee has not substantially
                  performed his duties; or
                           (ii) the willful engaging by Employee in gross
                  misconduct materially and demonstrably injurious to the
                  Company. No act, or failure to act, on Employee's part shall
                  be considered "willful" unless done, or omitted to be done, by
                  Employee in the absence of good faith and without a reasonable
                  belief that his action or failure to act was in the best
                  interest of the Company.

         For purposes of this Agreement, "Disability" shall mean a physical or
mental infirmity which impairs the Employee's ability substantially to perform
his employment duties for the Company and which continues for a period of at
least one hundred and eighty (180) consecutive days.
                  (B) The Employee terminates his employment with the Company
for "Good Reason." For purposes of this Agreement, "Good Reason" shall mean the
occurrence after a Change in Control of any of the following events or
conditions:
                           (i) a change in the Employee's status, title,
                  position or responsibilities (including reporting
                  responsibilities) which, in the Employee's reasonable
                  judgment, represents an adverse change from his status, title,
                  position or responsibilities in effect immediately prior
                  thereto; the assignment to Employee of any duties or
                  responsibilities which in the Employee's reasonable judgment,
                  are inconsistent with his status, title, position or
                  responsibilities; or any removal of Employee from or failure
                  to reappoint or reelect him to any of such positions, status,
                  or title except in connection with the termination of his
                  employment for Disability, Cause, or death, or by the Employee
                  other than for Good Reason;
                           (ii) a reduction in the Employee's base salary;
                           (iii) the Company's requiring the Employee to be 
                  based at any place outside a 30 mile radius from Durham, 
                  North Carolina, except for reasonably required travel on the 
                  Company's business which is not greater than such travel 
                  requirements prior to the Change in Control;
                           (iv) the failure by the Company to continue in effect
                  any compensation, welfare or benefit plan in which Employee is
                  participating at the time of a Change in Control without
                  substituting plans providing Employee with

                                        8

<PAGE>



                  substantially similar or greater benefits, or the taking of
                  any action by the Company which would adversely affect
                  Employee's participation in or materially reduce Employee's
                  benefits under any of such plans or deprive Employee of any
                  material fringe benefit enjoyed by Employee at the time of the
                  Change in Control;
                           (v)  any purported termination of Employee's 
                  employment for Cause or Disability without grounds therefore;
                           (vi)  the insolvency or the filing (by any party 
                  including the Company) of a petition for bankruptcy of the 
                  Company;
                           (vii)  any material breach by the Company of any 
                  provision of this Agreement; or
                           (viii) the failure of the Company to obtain an
                  agreement, satisfactory to the Employee, from any successor or
                  assign of the Company to assume and agree to perform this
                  Agreement.
         5.       Severance Pay and Benefits.  In the event that Employee's 
employment with the Company terminates under any of the circumstances described 
in Paragraph 4 above, Employee shall be entitled to receive all of the 
following:
                  (A)  all accrued compensation and any pro-rata bonuses 
Employee may have earned up to the Termination Date;
                  (B) a severance payment equal to two and nine-tenths (2.9)
times the amount of the Employee's most recent annual compensation, including
the amount of his most recent annual bonus. The severance payment shall be paid
in thirty-four (34) equal monthly installments without interest, commencing one
month after the Termination Date;

                                        9

<PAGE>



                  (C) a continuation of benefits. The Company shall maintain in
full force and effect, for two (2) years after the Termination Date, all life
insurance, health, accidental death and dismemberment, and disability plans and
other benefit programs in which Employee is entitled to participate immediately
prior to the Termination Date provided that Employee's continued participation
is possible under the general terms and provisions of such plans and programs.
Employee's continued participation in such plans and programs shall be at no
greater cost to Employee than the cost he bore for such participation
immediately prior to the Termination Date. If Employee's participation in any
such plan or program is barred, the Company shall arrange upon comparable terms,
and at no greater cost to Employee than the cost he bore for such plans and
programs prior to the Termination Date, to provide Employee with benefits
substantially similar to, or greater than, those which he is entitled to receive
under any such plan or program; and
                  (D) a lump sum payment (or otherwise as specified by Employee
to the extent permitted by the applicable plan) of any and all amounts
contributed to a Company pension or retirement plan which Employee is entitled
to under the terms of any such plan.
         6. No Duty to Mitigate. Employee shall not be required to mitigate the
amount of any payment provided for in this Agreement by seeking other employment
or otherwise, and no such payment shall be offset or reduced by the amount of
any compensation or benefits provided to the Employee in any subsequent
employment. The severance pay and benefits under this Agreement shall be in lieu
of any other severance pay to which Employee may be entitled from the Company.
         7. Stock Options.  Upon the occurrence of a Change in Control, all 
stock options shall immediately vest and, except as may be required by the 
nature of the transaction constituting the Change in Control, the options shall 
remain exercisable for the duration of the

                                       10

<PAGE>



original option term. If plans or agreements to which outstanding options have
been issued do not provide for immediate vesting, the Company shall use its best
efforts to effect amendments permitting the acceleration of vesting so long as
no material adverse accounting treatment results to the Company.
         8. Fees and Expenses. The Company agrees that if Employee is entitled
to any severance pay or benefits under this Agreement, and the Company or its
survivor disputes the obligation to pay such severance pay or benefits and the
Employee prevails, in whole or in part, the Company or its survivor shall
promptly pay or reimburse Employee for all expense incurred by Employee in such
dispute, including, but not limited to, attorneys fees and associated expenses.
         9.       Excise Tax Payments.
                  (A) In the event that any payment or benefit (within the
meaning of Section 280G(b)(2) of the Internal Revenue Code of 1986, as amended
(the "Code")), to the Employee or for his benefit paid or payable or distributed
or distributable pursuant to the terms of this Agreement or otherwise in
connection with, or arising out of, his employment with the Company or a change
in ownership or effective control of the Company or of a substantial portion of
its assets (a "Payment" or "Payments"), would be subject to the excise tax
imposed by Section 4999 of the Code or any interest or penalties are incurred by
the Employee with respect to such excise tax (such excise tax, together with any
such interest and penalties, are hereinafter collectively referred to as the
"Excise Tax"), then the Employee will be entitled to receive an additional
payment (a "Gross-Up Payment") in an amount such that after payment by the
Employee of all taxes (including any interest or penalties, other than interest
and penalties imposed by reason of the Employee's failure to file timely a tax
return or pay taxes shown due on his return, imposed with respect to such taxes
and the Excise

                                       11

<PAGE>



Tax), including any Excise Tax imposed upon the Gross-Up Payment, the Employee
retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon
the Payments.
                  (B) An initial determination as to whether a Gross-Up Payment
is required pursuant to this Agreement and the amount of such Gross-Up Payment
shall be made at the Company's expense by an accounting firm selected by the
Company and reasonably acceptable to the Employee which is designated as one of
the five largest accounting firms in the United States (the "Accounting Firm").
The Accounting Firm shall provide its determination (the "Determination"),
together with detailed supporting calculations and documentation to the Company
and the Employee within ten days of the Termination Date if applicable, or such
other time as requested by the Company or by the Employee (provided the Employee
reasonably believes that any of the Payments may be subject to the Excise Tax)
and if the Accounting Firm determines that no Excise Tax is payable by the
Employee with respect to a Payment or Payments, it shall furnish the Employee
with an opinion reasonably acceptable to the Employee that no Excise Tax will be
imposed with respect to any such Payment or Payments. Within ten days of the
delivery of the Determination to the Employee, the Employee shall have the right
to dispute the Determination (the "Dispute"). The Gross-Up Payment, if any, as
determined pursuant to this Paragraph 9(B) shall be paid by the Company to the
Employee within five days of the receipt of the Accounting Firm's determination.
The existence of the Dispute shall not in any way affect the Employee's right to
receive the Gross- Up Payment in accordance with the Determination . Upon the
final resolution of a Dispute, the Company shall promptly pay to the Employee
any additional amount required by such resolution. If there is no Dispute, the
Determination shall be binding, final and conclusive upon the Company and the
Employee subject to the application of Paragraph 9(C) below.

<PAGE>



                  (C) Notwithstanding anything in this Agreement to the
contrary, in the event that, according to the Determination, an Excise Tax will
be imposed on any Payment or Payments, the Company shall pay to the applicable
government taxing authorities as Excise Tax withholding, the amount of the
Excise Tax that the Company has actually withheld from the Payment or Payments.
         10.      Successors and Assigns.
                  (A) This Agreement shall be binding upon and shall inure to
the benefit of the Company, its successors, and assigns, and the Company shall
require any successor or assign to expressly assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession or assignment had taken place.
                  (B) Neither this Agreement nor any right or interest hereunder
shall be assignable or transferable by the Employee, his beneficiaries, or legal
representatives except by will or by the laws of dissent and distribution. This
Agreement shall inure to the benefit of and be enforceable by the Employee's
legal personal representative.
         11. Notice. Notice as provided for in this Agreement shall be in
writing and shall be deemed to have been duly given when delivered in person or
mailed by United States Registered Mail, Return Receipt Requested, Postage
Pre-Paid, addressed to the respective addresses last given by each party to the
other, provided that all notices to the Company shall be directed to the

27602-2611, counsel for the Company. All notices and communications shall be
deemed to have been received on the date of delivery thereof or on the third
business day of the mailing thereof, except that notice of change of address
shall be effective only upon receipt.

         12. Modifications. No provision of this Agreement may be modified,
waived, or discharged unless such modification, waiver, or discharge is agreed
to in writing signed by the Employee and the Company. No waiver by either party
hereto at any time of any breach by the other party hereto of, or compliance
with, any conditional provision of this Agreement to be performed by such other
party shall be deemed a waiver of similar or dissimilar provisions or conditions
of the same at any prior or subsequent time.
         13.      Entire Agreement.  No agreement or representations, oral or 
otherwise, express or implied, with respect to the subject matter hereof have 
been made by either party which are not expressly set forth in this Agreement.
         14.      Governing Law.  This Agreement shall be governed by and 
construed and enforced in accordance with the laws of the State of North 
Carolina.
         15.      Severability.  The provisions of this Agreement shall be 
deemed severable and the invalidity or unenforceability of any provision shall 
not affect the validity or enforceability of the other provisions hereof.
         IN WITNESS WHEREOF, the parties have executed this Agreement as of the

                                       CHANGE IN CONTROL SEVERANCE AGREEMENT

         THIS CHANGE IN CONTROL SEVERANCE AGREEMENT ("Agreement"), is made and
entered into this 21st day of May, 1996 by and between Embrex, Inc. ("Company"),
a North Carolina corporation, and Catherine A. Ricks ("Employee").
         WHEREAS, the Board of Directors ("Board") of the Company considers the
maintenance of a vital management group to be essential in protecting and
enhancing the best interests of the Company and its shareholders;
          WHEREAS, the Board recognizes that the possibility of a Change in
Control (as hereinafter defined) exists and that the threat of or the occurrence
of a Change in Control can result in significant distractions of its key
management personnel because of the uncertainties inherent in such a situation;
         WHEREAS, the Board has determined that it is in the best interest of
the Company and its shareholders to ensure the Employee's continued dedication
and efforts on behalf of the Company; and
         WHEREAS, in order to induce the Employee to remain in the employ of the
Company, particularly in the event of a threat of or the occurrence of a Change
in Control and to dispel any concerns that the Employee may have about taking an
active part in the defense against an inappropriate attempt to bring about a
Change in Control of the Company, the Company desires to enter into this
Agreement with the Employee to provide the Employee with certain payments and
benefits in the event that her employment with the Company is terminated as a
result of, or in connection with, a Change in Control.
         NOW, THEREFORE, in consideration of the mutual agreements herein set
forth, the legal sufficiency and adequacy of which are hereby acknowledged, the
parties agree as follows:

                                        1

<PAGE>



         1. Employment. Employee acknowledges that she is employed with the
Company pursuant to an Employment Agreement dated October 16, 1989 and hereby
agrees that to the extent any provision of this Agreement should be contrary to
any provision of the Employment Agreement, the terms of this Agreement shall
control.
         2.       Definitions.  For purposes of this Agreement, the following 
terms have the meanings indicated:
                  (A) "Acquiring Person" shall mean any Person (as such term is
hereinafter defined) who or which, together with all Affiliates (as such term is
hereinafter defined) and Associates (as such term is hereinafter defined) of
such Person, shall be the Beneficial Owner (as such term is hereinafter defined)
of thirty-three percent (33%) or more of the shares of Common Stock then
outstanding, but shall not include (i) the Company, (ii) any Subsidiary of the
Company, (iii) any employee benefit plan or employee stock plan of the Company
or of any Subsidiary of the Company, (iv) any dividend reinvestment plan of the
Company, or (v) any Person or entity organized, appointed, or established by the
Company for or pursuant to the terms of such plan. Notwithstanding the
foregoing, no Person shall become an "Acquiring Person" as the result of an
acquisition of Common Stock by the Company which, by reducing the number of
shares outstanding, increases the proportionate number of shares beneficially
owned by such Person to thirty-three percent (33%) or more of the Common Stock
of the Company then outstanding; provided, however, that if a Person shall
become the Beneficial Owner of thirty-three (33%) or more of the Common Stock of
the Company, then outstanding by reason of such an acquisition and shall, after
such acquisition, become the Beneficial Owner of any additional shares of Common
Stock, then such Person shall be deemed to be an "Acquiring Person." In
addition, notwithstanding the foregoing, if the Board of Directors of the
Company determines in good faith that a Person who would otherwise be an
"Acquiring

                                        2

<PAGE>



Person," as defined pursuant to the foregoing provisions of this Paragraph (A),
has become such inadvertently, and such Person divests as promptly as
practicable a sufficient number of shares of Common Stock so that such Person
would no longer be an "Acquiring Person" as defined pursuant to the foregoing
provisions of this Paragraph (A), then such Person shall not be deemed to be an
"Acquiring Person" for any purposes of this Agreement.
                  (B) "Affiliate" and "Associate" shall have the respective
meanings ascribed to such terms in Rule 12b-2 of the General Rules and
Regulations under the Securities Exchange Act of 1934, as amended (the "Exchange
Act").
                  (C) A Person shall be deemed the "Beneficial Owner" of and
shall be deemed to "beneficially own," any securities:
                           (i) which such Person or any of such Person's
                  Affiliates or Associates, directly or indirectly, has the
                  right or obligation to acquire (whether such right is
                  exercisable immediately or only after the passage of time)
                  pursuant to any agreement, arrangement or understanding
                  (whether or not in writing) or upon the exercise of conversion
                  rights, exchange rights, rights, warrants or options, or
                  otherwise; provided, however, that a Person shall not be
                  deemed the "Beneficial Owner" of, or to "beneficially own,"
                  (a) securities tendered pursuant to a tender or exchange offer
                  made by such Person or any of such Person's Affiliates or
                  Associates until such tendered securities are accepted for
                  purchase or exchange, or (b) at any time prior to the
                  occurrence of a Triggering Event, securities issuable upon
                  exercise of the Rights ("Triggering Event" and "Rights" shall
                  have the respective meanings ascribed to such terms as set
                  forth in the Rights Agreement between Embrex, Inc. and Branch
                  Banking & Trust Company as Rights Agent, dated as of March 21,
                  1996 and as in effect on the date

                                        3

<PAGE>



                  hereof ("Rights Agreement")), or (c) from and after the
                  occurrence of a Triggering Event, securities issuable upon
                  exercise of Rights which were acquired by such Person or any
                  of such Person's Affiliates or Associates prior to the
                  Distribution Date (as defined in the Rights Agreement) or
                  pursuant to Section 3(a) or Section 22 of the Rights Agreement
                  (the "Original Rights") or pursuant to Section 11(i) of the
                  Rights Agreement in connection with an adjustment made with
                  respect to any Original Rights;
                           (ii) which such Person or any of such Person's
                  Affiliates or Associates, directly or indirectly, has the
                  right to vote or dispose of or has "beneficial ownership" of
                  (as determined pursuant to Rule 13d-3 of the General Rules and
                  Regulations under the Exchange Act and any successor provision
                  thereof), including pursuant to any agreement, arrangement or
                  understanding, whether or not in writing; provided, however,
                  that a Person shall not be deemed the "Beneficial Owner" of,
                  or to "beneficially own," any security under this subparagraph
                  (ii) as a result of an agreement, arrangement or understanding
                  to vote such security if such agreement, arrangement or
                  understanding: (a) arises solely from a revocable proxy given
                  in response to a public proxy or consent solicitation made
                  pursuant to, and in accordance with, the applicable provisions
                  of the General Rules and Regulations under the Exchange Act,
                  and (b) is not also then reportable by such Person on Schedule
                  13D under the Exchange Act (or any comparable or successor
                  report); or
                           (iii) which are beneficially owned, directly or
                  indirectly, by any other Person (or any Affiliate or Associate
                  thereof) with which such Person (or any of such Person's
                  Affiliates or Associates) has any agreement, arrangement or

                                        4

                  understanding (whether or not in writing), but excluding
                  customary agreements with and between underwriters and selling
                  group members with respect to a bona fide public offering of

<PAGE>



                           (iii) the Company shall sell or otherwise transfer
                  (or one or more of its Subsidiaries shall sell or otherwise

         4. Termination Following Change in Control. After the occurrence of a
Change in Control, Employee shall be entitled to receive payments and benefits

Change in Control, her employment with the Company is terminated under any of
the following circumstances:
                  (A) The Company terminates Employee's employment for reasons
other than "Cause," "Disability," or death. For purposes of this Agreement,
"Cause" shall be defined as:
                           (i) the willful and continued failure by Employee to
                  perform substantially her duties with the Company (other than
                  any such failure resulting from her Disability) for a
                  significant period of time, after a demand for substantial
                  performance is delivered to Employee by the Board or a
                  committee thereof, which specifically identifies the manner in
                  which the Board believes that Employee has not substantially
                  performed her duties; or
                           (ii) the willful engaging by Employee in gross
                  misconduct materially and demonstrably injurious to the
                  Company. No act, or failure to act, on Employee's part shall
                  be considered "willful" unless done, or omitted to be done, by
                  Employee in the absence of good faith and without a reasonable
                  belief that her action or failure to act was in the best
                  interest of the Company.

                                        7

<PAGE>



         For purposes of this Agreement, "Disability" shall mean a physical or
mental infirmity which impairs the Employee's ability substantially to perform
her employment duties for the Company and which continues for a period of at
least one hundred and eighty (180) consecutive days.
                  (B) The Employee terminates her employment with the Company
for "Good Reason." For purposes of this Agreement, "Good Reason" shall mean the
occurrence after a Change in Control of any of the following events or
conditions:
                           (i) a change in the Employee's status, title,
                  position or responsibilities (including reporting
                  responsibilities) which, in the Employee's reasonable
                  judgment, represents an adverse change from her status, title,
                  position or responsibilities in effect immediately prior
                  thereto; the assignment to Employee of any duties or
                  responsibilities which in the Employee's reasonable judgment,
                  are inconsistent with her status, title, position or
                  responsibilities; or any removal of Employee from or failure
                  to reappoint or reelect him to any of such positions, status,
                  or title except in connection with the termination of her
                  employment for Disability, Cause, or death, or by the Employee
                  other than for Good Reason;
                 (ii) a reduction in the Employee's base salary;
                 (iii) the Company's requiring the Employee to be based at any 
                  place outside a 30 mile radius from Durham, North Carolina, 
                  except for reasonably required travel on the Company's 
                  business which is not greater than such travel requirements 
                  prior to the Change in Control;
                           (iv)  the failure by the Company to continue in 
                  effect any compensation, welfare or benefit plan in which 
                  Employee is participating at the time of a

                                        8

<PAGE>



                  Change in Control without substituting plans providing
                  Employee with substantially similar or greater benefits, or
                  the taking of any action by the Company which would adversely
                  affect Employee's participation in or materially reduce
                  Employee's benefits under any of such plans or deprive
                  Employee of any material fringe benefit enjoyed by Employee at
                  the time of the Change in Control;
                           (v)  any purported termination of Employee's 
                  employment for Cause or Disability without grounds therefore;
                           (vi)  the insolvency or the filing (by any party 
                  including the Company) ofa petition for bankruptcy of the 
                  Company;
                           (vii)  any material breach by the Company of any 
                  provision of this Agreement; or
                           (viii) the failure of the Company to obtain an
                  agreement, satisfactory to the Employee, from any successor or
                  assign of the Company to assume and agree to perform this
                  Agreement.
         5.       Severance Pay and Benefits.  In the event that Employee's 
employment with the Company terminates under any of the circumstances described 
in Paragraph 4 above, Employee shall be entitled to receive all of the 
following:
                  (A)  all accrued compensation and any pro-rata bonuses 
Employee may have earned up to the Termination Date;
                  (B) a severance payment equal to two and nine-tenths (2.9)
times the amount of the Employee's most recent annual compensation, including
the amount of her most recent annual bonus. The severance payment shall be paid
in thirty-four (34) equal monthly installments without interest, commencing one
month after the Termination Date;

                                        9

<PAGE>



                  (C) a continuation of benefits. The Company shall maintain in
full force and effect, for two (2) years after the Termination Date, all life
insurance, health, accidental death and dismemberment, and disability plans and
other benefit programs in which Employee is entitled to participate immediately
prior to the Termination Date provided that Employee's continued participation
is possible under the general terms and provisions of such plans and programs.
Employee's continued participation in such plans and programs shall be at no
greater cost to Employee than the cost she bore for such participation
immediately prior to the Termination Date. If Employee's participation in any
such plan or program is barred, the Company shall arrange upon comparable terms,
and at no greater cost to Employee than the cost she bore for such plans and
programs prior to the Termination Date, to provide Employee with benefits
substantially similar to, or greater than, those which she is entitled to
receive under any such plan or program; and
                  (D) a lump sum payment (or otherwise as specified by Employee
to the extent permitted by the applicable plan) of any and all amounts
contributed to a Company pension or retirement plan which Employee is entitled
to under the terms of any such plan.
         6. No Duty to Mitigate. Employee shall not be required to mitigate the
amount of any payment provided for in this Agreement by seeking other employment
or otherwise, and no such payment shall be offset or reduced by the amount of
any compensation or benefits provided to the Employee in any subsequent
employment. The severance pay and benefits under this Agreement shall be in lieu
of any other severance pay to which Employee may be entitled from the Company.
         7. Stock Options.  Upon the occurrence of a Change in Control, all 
stock options shall immediately vest and, except as may be required by the 
nature of the transaction constituting the Change in Control, the options shall 
remain exercisable for the duration of the

                                       10

<PAGE>



original option term. If plans or agreements to which outstanding options have
been issued do not provide for immediate vesting, the Company shall use its best
efforts to effect amendments permitting the acceleration of vesting so long as
no material adverse accounting treatment results to the Company.
         8. Fees and Expenses. The Company agrees that if Employee is entitled
to any severance pay or benefits under this Agreement, and the Company or its
survivor disputes the obligation to pay such severance pay or benefits and the
Employee prevails, in whole or in part, the Company or its survivor shall
promptly pay or reimburse Employee for all expense incurred by Employee in such
dispute, including, but not limited to, attorneys fees and associated expenses.
         9.       Excise Tax Payments.
                  (A) In the event that any payment or benefit (within the
meaning of Section 280G(b)(2) of the Internal Revenue Code of 1986, as amended
(the "Code")), to the Employee or for her benefit paid or payable or distributed
or distributable pursuant to the terms of this Agreement or otherwise in
connection with, or arising out of, her employment with the Company or a change
in ownership or effective control of the Company or of a substantial portion of
its assets (a "Payment" or "Payments"), would be subject to the excise tax
imposed by Section 4999 of the Code or any interest or penalties are incurred by
the Employee with respect to such excise tax (such excise tax, together with any
such interest and penalties, are hereinafter collectively referred to as the
"Excise Tax"), then the Employee will be entitled to receive an additional
payment (a "Gross-Up Payment") in an amount such that after payment by the
Employee of all taxes (including any interest or penalties, other than interest
and penalties imposed by reason of the Employee's failure to file timely a tax
return or pay taxes shown due on her return, imposed with respect to such taxes
and the Excise

                                       11

<PAGE>



Tax), including any Excise Tax imposed upon the Gross-Up Payment, the Employee
retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon
the Payments.
                  (B) An initial determination as to whether a Gross-Up Payment
is required pursuant to this Agreement and the amount of such Gross-Up Payment
shall be made at the Company's expense by an accounting firm selected by the
Company and reasonably acceptable to the Employee which is designated as one of
the five largest accounting firms in the United States (the "Accounting Firm").
The Accounting Firm shall provide its determination (the "Determination"),
together with detailed supporting calculations and documentation to the Company
and the Employee within ten days of the Termination Date if applicable, or such
other time as requested by the Company or by the Employee (provided the Employee
reasonably believes that any of the Payments may be subject to the Excise Tax)
and if the Accounting Firm determines that no Excise Tax is payable by the
Employee with respect to a Payment or Payments, it shall furnish the Employee
with an opinion reasonably acceptable to the Employee that no Excise Tax will be
imposed with respect to any such Payment or Payments. Within ten days of the
delivery of the Determination to the Employee, the Employee shall have the right
to dispute the Determination (the "Dispute"). The Gross-Up Payment, if any, as
determined pursuant to this Paragraph 9(B) shall be paid by the Company to the
Employee within five days of the receipt of the Accounting Firm's determination.
The existence of the Dispute shall not in any way affect the Employee's right to
receive the Gross-Up Payment in accordance with the Determination . Upon the
final resolution of a Dispute, the Company shall promptly pay to the Employee
any additional amount required by such resolution. If there is no Dispute, the
Determination shall be binding, final and conclusive upon the Company and the
Employee subject to the application of Paragraph 9(C) below.

                                       12

<PAGE>



                  (C) Notwithstanding anything in this Agreement to the
contrary, in the event that, according to the Determination, an Excise Tax will
be imposed on any Payment or Payments, the Company shall pay to the applicable
government taxing authorities as Excise Tax withholding, the amount of the
Excise Tax that the Company has actually withheld from the Payment or Payments.
         10.      Successors and Assigns.
                  (A) This Agreement shall be binding upon and shall inure to
the benefit of the Company, its successors, and assigns, and the Company shall
require any successor or assign to expressly assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession or assignment had taken place.
                  (B) Neither this Agreement nor any right or interest hereunder
shall be assignable or transferable by the Employee, her beneficiaries, or legal
representatives except by will or by the laws of dissent and distribution. This
Agreement shall inure to the benefit of and be enforceable by the Employee's
legal personal representative.
         11. Notice. Notice as provided for in this Agreement shall be in
writing and shall be deemed to have been duly given when delivered in person or
mailed by United States Registered Mail, Return Receipt Requested, Postage
Pre-Paid, addressed to the respective addresses last given by each party to the
other, provided that all notices to the Company shall be directed to the

         12. Modifications. No provision of this Agreement may be modified,
waived, or discharged unless such modification, waiver, or discharge is agreed
to in writing signed by the Employee and the Company. No waiver by either party
hereto at any time of any breach by the other party hereto of, or compliance
with, any conditional provision of this Agreement to be performed by such other
party shall be deemed a waiver of similar or dissimilar provisions or conditions
of the same at any prior or subsequent time.
         13.      Entire Agreement.  No agreement or representations, oral or 
otherwise, express or implied, with respect to the subject matter hereof have 
been made by either party which are not expressly set forth in this Agreement.

construed and enforced in accordance with the laws of the State of North 
Carolina.
         15.      Severability.  The provisions of this Agreement shall be

                      CHANGE IN CONTROL SEVERANCE AGREEMENT

         THIS CHANGE IN CONTROL SEVERANCE AGREEMENT ("Agreement"), is made and
entered into this 21st day of May, 1996 by and between Embrex, Inc. ("Company"),
a North Carolina corporation, and Brian V. Cosgriff ("Employee").
         WHEREAS, the Board of Directors ("Board") of the Company considers the
maintenance of a vital management group to be essential in protecting and
enhancing the best interests of the Company and its shareholders;
          WHEREAS, the Board recognizes that the possibility of a Change in
Control (as hereinafter defined) exists and that the threat of or the occurrence
of a Change in Control can result in significant distractions of its key
management personnel because of the uncertainties inherent in such a situation;
         WHEREAS, the Board has determined that it is in the best interest of
the Company and its shareholders to ensure the Employee's continued dedication
and efforts on behalf of the Company; and
         WHEREAS, in order to induce the Employee to remain in the employ of the
Company, particularly in the event of a threat of or the occurrence of a Change
in Control and to dispel any concerns that the Employee may have about taking an
active part in the defense against an inappropriate attempt to bring about a
Change in Control of the Company, the Company desires to enter into this
Agreement with the Employee to provide the Employee with certain payments and
benefits in the event that his employment with the Company is terminated as a
result of, or in connection with, a Change in Control.
         NOW, THEREFORE, in consideration of the mutual agreements herein set
forth, the legal sufficiency and adequacy of which are hereby acknowledged, the
parties agree as follows:

                                        1

<PAGE>



         1. Employment. Employee acknowledges that he is employed with the
Company pursuant to an Employment Agreement dated August 18, 1995 and hereby
agrees that to the extent any provision of this Agreement should be contrary to
any provision of the Employment Agreement, the terms of this Agreement shall
control.
         2.       Definitions.  For purposes of this Agreement, the following 
terms have the meanings indicated:
                  (A) "Acquiring Person" shall mean any Person (as such term is
hereinafter defined) who or which, together with all Affiliates (as such term is
hereinafter defined) and Associates (as such term is hereinafter defined) of
such Person, shall be the Beneficial Owner (as such term is hereinafter defined)
of thirty-three percent (33%) or more of the shares of Common Stock then
outstanding, but shall not include (i) the Company, (ii) any Subsidiary of the
Company, (iii) any employee benefit plan or employee stock plan of the Company
or of any Subsidiary of the Company, (iv) any dividend reinvestment plan of the
Company, or (v) any Person or entity organized, appointed, or established by the
Company for or pursuant to the terms of such plan. Notwithstanding the
foregoing, no Person shall become an "Acquiring Person" as the result of an
acquisition of Common Stock by the Company which, by reducing the number of
shares outstanding, increases the proportionate number of shares beneficially
owned by such Person to thirty-three percent (33%) or more of the Common Stock
of the Company then outstanding; provided, however, that if a Person shall
become the Beneficial Owner of thirty-three (33%) or more of the Common Stock of
the Company, then outstanding by reason of such an acquisition and shall, after
such acquisition, become the Beneficial Owner of any additional shares of Common
Stock, then such Person shall be deemed to be an "Acquiring Person." In
addition, notwithstanding the foregoing, if the Board of Directors of the
Company determines in good faith that a Person who would otherwise be an
"Acquiring

                                        2

<PAGE>



Person," as defined pursuant to the foregoing provisions of this Paragraph (A),
has become such inadvertently, and such Person divests as promptly as
practicable a sufficient number of shares of Common Stock so that such Person
would no longer be an "Acquiring Person" as defined pursuant to the foregoing
provisions of this Paragraph (A), then such Person shall not be deemed to be an
"Acquiring Person" for any purposes of this Agreement.
                  (B) "Affiliate" and "Associate" shall have the respective
meanings ascribed to such terms in Rule 12b-2 of the General Rules and
Regulations under the Securities Exchange Act of 1934, as amended (the "Exchange
Act").
                  (C) A Person shall be deemed the "Beneficial Owner" of and
shall be deemed to "beneficially own," any securities:
                           (i) which such Person or any of such Person's
                  Affiliates or Associates, directly or indirectly, has the
                  right or obligation to acquire (whether such right is
                  exercisable immediately or only after the passage of time)

<PAGE>



                           (iii) the Company shall sell or otherwise transfer
                  (or one or more of its Subsidiaries shall sell or otherwise

         4. Termination Following Change in Control. After the occurrence of a
Change in Control, Employee shall be entitled to receive payments and benefits

Change in Control, his employment with the Company is terminated under any of
the following circumstances:
                  (A) The Company terminates Employee's employment for reasons
other than "Cause," "Disability," or death. For purposes of this Agreement,
"Cause" shall be defined as:
                           (i) the willful and continued failure by Employee to
                  perform substantially his duties with the Company (other than
                  any such failure resulting from his Disability) for a
                  significant period of time, after a demand for substantial
                  performance is delivered to Employee by the Board or a
                  committee thereof, which specifically identifies the manner in
                  which the Board believes that Employee has not substantially
                  performed his duties; or
                           (ii) the willful engaging by Employee in gross
                  misconduct materially and demonstrably injurious to the
                  Company. No act, or failure to act, on Employee's part shall
                  be considered "willful" unless done, or omitted to be done, by
                  Employee in the absence of good faith and without a reasonable
                  belief that his action or failure to act was in the best
                  interest of the Company.

                                        7

         For purposes of this Agreement, "Disability" shall mean a physical or
mental infirmity which impairs the Employee's ability substantially to perform
his employment duties for the Company and which continues for a period of at
least one hundred and eighty (180) consecutive days.
                  (B) The Employee terminates his employment with the Company
for "Good Reason." For purposes of this Agreement, "Good Reason" shall mean the
occurrence after a Change in Control of any of the following events or
conditions:
                           (i) a change in the Employee's status, title,
                  position or responsibilities (including reporting
                  responsibilities) which, in the Employee's reasonable
                  judgment, represents an adverse change from his status, title,
                  position or responsibilities in effect immediately prior
                  thereto; the assignment to Employee of any duties or
                  responsibilities which in the Employee's reasonable judgment,
                  are inconsistent with his status, title, position or
                  responsibilities; or any removal of Employee from or failure
                  to reappoint or reelect him to any of such positions, status,
                  or title except in connection with the termination of his
                  employment for Disability, Cause, or death, or by the Employee
                  other than for Good Reason;
                 (ii) a reduction in the Employee's base salary;
                 (iii) the Company's requiring the Employee to be based at any 
                  place outside a 30 mile radius from Durham, North Carolina, 
                  except for reasonably required travel on the Company's 
                  business which is not greater than such travel requirements 
                  prior to the Change in Control;
                           (iv) the failure by the Company to continue in effect
                  any compensation, welfare or benefit plan in which Employee is
                  participating at the time of a Change in Control without
                  substituting plans providing Employee with

                                        8

<PAGE>



                  substantially similar or greater benefits, or the taking of
                  any action by the Company which would adversely affect
                  Employee's participation in or materially reduce Employee's
                  benefits under any of such plans or deprive Employee of any
                  material fringe benefit enjoyed by Employee at the time of the
                  Change in Control;
                           (v) any purported termination of Employee's 
                  employment for Cause or Disability without grounds therefore;
                           (vi)  the insolvency or the filing (by any party 
                  including the Company) of a petition for bankruptcy of the 
                  Company;
                           (vii)  any material breach by the Company of any 
                  provision of this Agreement; or
                           (viii) the failure of the Company to obtain an
                  agreement, satisfactory to the Employee, from any successor or
                  assign of the Company to assume and agree to perform this
                  Agreement.
         5.       Severance Pay and Benefits.  In the event that Employee's 
employment with the Company terminates under any of the circumstances described 
in Paragraph 4 above, Employee shall be entitled to receive all of the 
following:
                  (A)  all accrued compensation and any pro-rata bonuses 
Employee may have earned up to the Termination Date;
                  (B) a severance payment equal to two and nine-tenths (2.9)
times the amount of the Employee's most recent annual compensation, including
the amount of his most recent annual bonus. The severance payment shall be paid
in thirty-four (34) equal monthly installments without interest, commencing one
month after the Termination Date;

                                        9

<PAGE>



                  (C) a continuation of benefits. The Company shall maintain in
full force and effect, for two (2) years after the Termination Date, all life
insurance, health, accidental death and dismemberment, and disability plans and
other benefit programs in which Employee is entitled to participate immediately
prior to the Termination Date provided that Employee's continued participation
is possible under the general terms and provisions of such plans and programs.
Employee's continued participation in such plans and programs shall be at no
greater cost to Employee than the cost he bore for such participation
immediately prior to the Termination Date. If Employee's participation in any
such plan or program is barred, the Company shall arrange upon comparable terms,
and at no greater cost to Employee than the cost he bore for such plans and
programs prior to the Termination Date, to provide Employee with benefits
substantially similar to, or greater than, those which he is entitled to receive
under any such plan or program; and
                  (D) a lump sum payment (or otherwise as specified by Employee
to the extent permitted by the applicable plan) of any and all amounts
contributed to a Company pension or retirement plan which Employee is entitled
to under the terms of any such plan.
         6. No Duty to Mitigate. Employee shall not be required to mitigate the
amount of any payment provided for in this Agreement by seeking other employment
or otherwise, and no such payment shall be offset or reduced by the amount of
any compensation or benefits provided to the Employee in any subsequent
employment. The severance pay and benefits under this Agreement shall be in lieu
of any other severance pay to which Employee may be entitled from the Company.
         7.       Stock Options.  Upon the occurrence of a Change in Control, 
all stock options shall immediately vest and, except as may be required by the 
nature of the transaction constituting the Change in Control, the options shall 
remain exercisable for the duration of the

                                       10

<PAGE>



original option term. If plans or agreements to which outstanding options have
been issued do not provide for immediate vesting, the Company shall use its best
efforts to effect amendments permitting the acceleration of vesting so long as
no material adverse accounting treatment results to the Company.
         8. Fees and Expenses. The Company agrees that if Employee is entitled
to any severance pay or benefits under this Agreement, and the Company or its
survivor disputes the obligation to pay such severance pay or benefits and the
Employee prevails, in whole or in part, the Company or its survivor shall
promptly pay or reimburse Employee for all expense incurred by Employee in such
dispute, including, but not limited to, attorneys fees and associated expenses.
         9.       Excise Tax Payments.
                  (A) In the event that any payment or benefit (within the
meaning of Section 280G(b)(2) of the Internal Revenue Code of 1986, as amended
(the "Code")), to the Employee or for his benefit paid or payable or distributed
or distributable pursuant to the terms of this Agreement or otherwise in
connection with, or arising out of, his employment with the Company or a change
in ownership or effective control of the Company or of a substantial portion of
its assets (a "Payment" or "Payments"), would be subject to the excise tax
imposed by Section 4999 of the Code or any interest or penalties are incurred by
the Employee with respect to such excise tax (such excise tax, together with any
such interest and penalties, are hereinafter collectively referred to as the
"Excise Tax"), then the Employee will be entitled to receive an additional
payment (a "Gross-Up Payment") in an amount such that after payment by the
Employee of all taxes (including any interest or penalties, other than interest
and penalties imposed by reason of the Employee's failure to file timely a tax
return or pay taxes shown due on his return, imposed with respect to such taxes
and the Excise

                                       11

<PAGE>



Tax), including any Excise Tax imposed upon the Gross-Up Payment, the Employee
retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon
the Payments.
                  (B) An initial determination as to whether a Gross-Up Payment
is required pursuant to this Agreement and the amount of such Gross-Up Payment
shall be made at the Company's expense by an accounting firm selected by the
Company and reasonably acceptable to the Employee which is designated as one of
the five largest accounting firms in the United States (the "Accounting Firm").
The Accounting Firm shall provide its determination (the "Determination"),
together with detailed supporting calculations and documentation to the Company
and the Employee within ten days of the Termination Date if applicable, or such
other time as requested by the Company or by the Employee (provided the Employee
reasonably believes that any of the Payments may be subject to the Excise Tax)
and if the Accounting Firm determines that no Excise Tax is payable by the
Employee with respect to a Payment or Payments, it shall furnish the Employee
with an opinion reasonably acceptable to the Employee that no Excise Tax will be
imposed with respect to any such Payment or Payments. Within ten days of the
delivery of the Determination to the Employee, the Employee shall have the right
to dispute the Determination (the "Dispute"). The Gross-Up Payment, if any, as
determined pursuant to this Paragraph 9(B) shall be paid by the Company to the
Employee within five days of the receipt of the Accounting Firm's determination.
The existence of the Dispute shall not in any way affect the Employee's right to
receive the Gross-Up Payment in accordance with the Determination . Upon the
final resolution of a Dispute, the Company shall promptly pay to the Employee
any additional amount required by such resolution. If there is no Dispute, the
Determination shall be binding, final and conclusive upon the Company and the
Employee subject to the application of Paragraph 9(C) below.

<PAGE>



                  (C) Notwithstanding anything in this Agreement to the
contrary, in the event that, according to the Determination, an Excise Tax will
be imposed on any Payment or Payments, the Company shall pay to the applicable
government taxing authorities as Excise Tax withholding, the amount of the
Excise Tax that the Company has actually withheld from the Payment or Payments.
         10.      Successors and Assigns.
                  (A) This Agreement shall be binding upon and shall inure to
the benefit of the Company, its successors, and assigns, and the Company shall
require any successor or assign to expressly assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession or assignment had taken place.
                  (B) Neither this Agreement nor any right or interest hereunder
shall be assignable or transferable by the Employee, his beneficiaries, or legal
representatives except by will or by the laws of dissent and distribution. This
Agreement shall inure to the benefit of and be enforceable by the Employee's
legal personal representative.
         11. Notice. Notice as provided for in this Agreement shall be in

otherwise, express or implied, with respect to the subject matter hereof have

                      CHANGE IN CONTROL SEVERANCE AGREEMENT


         THIS CHANGE IN CONTROL SEVERANCE AGREEMENT ("Agreement"), is made and
entered into this 9th day of June, 1996 by and between Embrex, Inc., including
its wholly-owned subsidiary, Embrex Europe Limited (hereinafter Embrex, Inc. and
Embrex Europe Limited are collectively referred to as "Company"), and David M.
Baines ("Employee").
         WHEREAS, the Board of Directors ("Board") of the Company considers the
maintenance of a vital management group to be essential in protecting and
enhancing the best interests of the Company and its shareholders;
          WHEREAS, the Board recognizes that the possibility of a Change in
Control (as hereinafter defined) exists and that the threat of or the occurrence
of a Change in Control can result in significant distractions of its key
management personnel because of the uncertainties inherent in such a situation;
         WHEREAS, Employee is currently a member of the key management of both 
Embrex, Inc. and Embrex Europe Limited;
         WHEREAS, the Board has determined that it is in the best interest of
the Company and its shareholders to ensure the Employee's continued dedication
and efforts on behalf of the Company; and
         WHEREAS, in order to induce the Employee to remain in the employ of the
Company, particularly in the event of a threat of or the occurrence of a Change
in Control and to dispel any concerns that the Employee may have about taking an
active part in the defense against an inappropriate attempt to bring about a
Change in Control of the Company, the Company desires to enter into this
Agreement with the Employee to provide the Employee with certain


<PAGE>



payments and benefits in the event that his employment with the Company is
terminated as a result of, or in connection with, a Change in Control.
         NOW, THEREFORE, in consideration of the mutual agreements herein set
forth, the legal sufficiency and adequacy of which are hereby acknowledged, the
parties agree as follows:
         1. Employment. Employee acknowledges that he is employed by Embrex
Europe Limited pursuant to an Employment Agreement dated April 1, 1994 and
hereby agrees that to the extent any provision of this Agreement should be
contrary to any provision of the Employment Agreement, the terms of this
Agreement shall control.
         2. Definitions. For purposes of this Agreement, the following terms 
have the meanings indicated:
                  (A) "Acquiring Person" shall mean any Person (as such term is
hereinafter defined) who or which, together with all Affiliates (as such term is
hereinafter defined) and Associates (as such term is hereinafter defined) of
such Person, shall be the Beneficial Owner (as such term is hereinafter defined)
of thirty-three percent (33%) or more of the shares of Common Stock (as such
term is hereinafter defined) then outstanding, but shall not include (i) the
Company, (ii) any Subsidiary of the Company, (iii) any employee benefit plan or
employee stock plan of the Company or of any Subsidiary of the Company, (iv) any
dividend reinvestment plan of the Company, or (v) any Person or entity
organized, appointed, or established by the Company for or pursuant to the terms
of such plan. Notwithstanding the foregoing, no Person shall become an
"Acquiring Person" as the result of an acquisition of Common Stock by the
Company which, by reducing the number of shares outstanding, increases the
proportionate number of shares beneficially owned by such Person to thirty-three
percent (33%) or more of the Common Stock then outstanding; provided, however,
that

                                        2

<PAGE>



if a Person shall become the Beneficial Owner of thirty-three percent (33%) or
more of the Common Stock, then outstanding by reason of such an acquisition and
shall, after such acquisition, become the Beneficial Owner of any additional
shares of Common Stock, then such Person shall be deemed to be an "Acquiring
Person." In addition, notwithstanding the foregoing, if the Board of Directors
of the Company determines in good faith that a Person who would otherwise be an
"Acquiring Person," as defined pursuant to the foregoing provisions of this
Paragraph (A), has become such inadvertently, and such Person divests as
promptly as practicable a sufficient number of shares of Common Stock so that
such Person would no longer be an "Acquiring Person" as defined pursuant to the
foregoing provisions of this Paragraph (A), then such Person shall not be deemed
to be an "Acquiring Person" for any purposes of this Agreement.
                  (B) "Affiliate" and "Associate" shall have the respective
meanings ascribed to such terms in Rule 12b-2 of the General Rules and
Regulations under the Securities Exchange Act of 1934, as amended (the "Exchange
Act").
                  (C) A Person shall be deemed the "Beneficial Owner" of and
shall be deemed to "beneficially own," any securities:
                           (i) which such Person or any of such Person's
                  Affiliates or Associates, directly or indirectly, has the
                  right or obligation to acquire (whether such right is
                  exercisable immediately or only after the passage of time)
                  pursuant to any agreement, arrangement or understanding
                  (whether or not in writing) or upon the exercise of conversion
                  rights, exchange rights, rights, warrants or options, or
                  otherwise; provided, however, that a Person shall not be
                  deemed the "Beneficial Owner" of, or to "beneficially own,"
                  (a) securities tendered pursuant to a tender or exchange offer
                  made by such Person or any of such Person's

                                        3

<PAGE>



                  Affiliates or Associates until such tendered securities are
                  accepted for purchase or exchange, or (b) at any time prior to
                  the occurrence of a Triggering Event, securities issuable upon
                  exercise of the Rights ("Triggering Event" and "Rights" shall
                  have the respective meanings ascribed to such terms as set
                  forth in the Rights Agreement between Embrex, Inc. and Branch
                  Banking & Trust Company as Rights Agent, dated as of March 21,
                  1996 and as in effect on the date hereof ("Rights
                  Agreement")), or (c) from and after the occurrence of a
                  Triggering Event, securities issuable upon exercise of Rights
                  which were acquired by such Person or any of such Person's
                  Affiliates or Associates prior to the Distribution Date (as
                  defined in the Rights Agreement) or pursuant to Section 3(a)
                  or Section 22 of the Rights Agreement (the "Original Rights")
                  or pursuant to Section 11(i) of the Rights Agreement in
                  connection with an adjustment made with respect to any
                  Original Rights;
                           (ii) which such Person or any of such Person's
                  Affiliates or Associates, directly or indirectly, has the
                  right to vote or dispose of or has "beneficial ownership" of
                  (as determined pursuant to Rule 13d-3 of the General Rules and
                  Regulations under the Exchange Act and any successor provision
                  thereof), including pursuant to any agreement, arrangement or
                  understanding, whether or not in writing; provided, however,
                  that a Person shall not be deemed the "Beneficial Owner" of,
                  or to "beneficially own," any security under this subparagraph
                  (ii) as a result of an agreement, arrangement or understanding
                  to vote such security if such agreement, arrangement or
                  understanding: (a) arises solely from a revocable proxy given
                  in response to a public proxy or consent solicitation made
                  pursuant to, and in accordance with, the applicable provisions

                                        4

                  13D under the Exchange Act (or any comparable or successor
                  report); or
                           (iii) which are beneficially owned, directly or
                  indirectly, by any other Person (or any Affiliate or Associate
                  thereof) with which such Person (or any of such Person's
                  Affiliates or Associates) has any agreement, arrangement or

                  group members with respect to a bona fide public offering of

                  voting (except pursuant to a revocable proxy as described in
                  the provision to subparagraph (ii) of this paragraph (C)) or
                  disposing of any voting securities of the Company.

                  Company), and the Company shall

                  not be the continuing or surviving corporation of such

         4. Termination Following Change in Control. After the occurrence of a
Change in Control, Employee shall be entitled to receive payments and benefits
pursuant to this Agreement if, within two (2) years after the occurrence of a
Change in Control, his employment with the Company is terminated under any of
the following circumstances:
                  (A) The Company terminates Employee's employment for reasons
other than "Cause," "Disability," or death. For purposes of this Agreement,
"Cause" shall be defined as:
                           (i) the willful and continued failure by Employee to
                  perform substantially his duties with the Company (other than
                  any such failure resulting from his Disability) for a
                  significant period of time, after a demand for substantial
                  performance is delivered to Employee by the Board or a
                  committee thereof, 


                                       7

<PAGE>


                  which specifically identifies the manner in which the Board 
                  believes that Employee has not substantially performed his 
                  duties; or
                           (ii) the willful engaging by Employee in gross
                  misconduct materially and demonstrably injurious to the
                  Company. No act, or failure to act, on Employee's part shall
                  be considered "willful" unless done, or omitted to be done, by
                  Employee in the absence of good faith and without a reasonable
                  belief that his action or failure to act was in the best
                  interest of the Company.

         For purposes of this Agreement, "Disability" shall mean a physical or
mental infirmity which impairs the Employee's ability substantially to perform
his employment duties for the Company and which continues for a period of at
least one hundred and eighty (180) consecutive days.
                  (B) The Employee terminates his employment with the Company
for "Good Reason." For purposes of this Agreement, "Good Reason" shall mean the
occurrence after a Change in Control of any of the following events or
conditions:
                           (i) a change in the Employee's status, title,
                  position or responsibilities (including reporting
                  responsibilities) which, in the Employee's reasonable
                  judgment, represents an adverse change from his status, title,
                  position or responsibilities in effect immediately prior
                  thereto; the assignment to Employee of any duties or
                  responsibilities which in the Employee's reasonable judgment,
                  are inconsistent with his status, title, position or
                  responsibilities; or any removal of Employee from or failure
                  to reappoint or reelect him to any of such positions, status,
                  or title except in connection with the termination of his
                  employment for Disability, Cause, or death, or by the Employee
                  other than for Good Reason;
                           (ii) a reduction in the Employee's base salary;

                                       8

<PAGE>


                           (iii) the Company's requiring the Employee to be 
                  based at any place outside a 30 mile radius from Great Dunmow,
                  Essex, Great Britain, except for reasonably required travel on
                  the Company's business which is not greater than such travel 
                  requirements prior to the Change in Control;
                           (iv) the failure by the Company to continue in effect
                  any compensation, welfare or benefit plan in which Employee is
                  participating at the time of a Change in Control without
                  substituting plans providing Employee with substantially 
                  similar or greater benefits, or the taking of any action by 
                  the Company which would adversely affect Employee's 
                  participation in or materially reduce Employee's benefits 
                  under any of such plans or deprive Employee of any material 
                  fringe benefit enjoyed by Employee at the time of the
                  Change in Control;
                           (v)  any purported termination of Employee's 
                  employment for Cause or Disability without grounds therefore;
                           (vi)  the insolvency or the filing (by any party 
                  including the Company) of a petition for bankruptcy of the 
                  Company;
                           (vii)  any material breach by the Company of any 
                  provision of this Agreement; or
                           (viii) the failure of the Company to obtain an
                  agreement, satisfactory to the Employee, from any successor or
                  assign of the Company to assume and agree to perform this
                  Agreement.
         5.       Severance Pay and Benefits.  In the event that Employee's 
employment with the Company terminates under any of the circumstances described 
in Paragraph 4 above, Employee shall be entitled to receive all of the 
following:

                                       9

<PAGE>


                  (A)  all accrued compensation and any pro-rata bonuses 
Employee may have earned up to the Termination Date;
                  (B) a severance payment equal to two and nine-tenths (2.9)
times the amount of the Employee's most recent annual compensation, including
the amount of his most recent annual bonus. The severance payment shall be paid
in thirty-four (34) equal monthly installments without interest, commencing one
month after the Termination Date;
                  (C) a continuation of benefits. The Company shall maintain in
full force and effect, for two (2) years after the Termination Date, all life
insurance, health, accidental death and dismemberment, and disability plans and
other benefit programs in which Employee is entitled to participate immediately
prior to the Termination Date provided that Employee's continued participation
is possible under the general terms and provisions of such plans and programs.
Employee's continued participation in such plans and programs shall be at no
greater cost to Employee than the cost he bore for such participation
immediately prior to the Termination Date. If Employee's participation in any
such plan or program is barred, the Company shall arrange upon comparable terms,
and at no greater cost to Employee than the cost he bore for such plans and
programs prior to the Termination Date, to provide Employee with benefits
substantially similar to, or greater than, those which he is entitled to receive
under any such plan or program; and
                  (D) a lump sum payment (or otherwise as specified by Employee
to the extent permitted by the applicable plan) of any and all amounts
contributed to a Company pension or retirement plan which Employee is entitled
to under the terms of any such plan.
         6. No Duty to Mitigate. Employee shall not be required to mitigate the
amount of any payment provided for in this Agreement by seeking other employment
or otherwise, and 

                                       10
<PAGE>


no such payment shall be offset or reduced by the amount of any compensation or 
benefits provided to the Employee in any subsequent employment. The severance 
pay and benefits under this Agreement shall be in lieu of any other severance 
pay to which Employee may be entitled from the Company.
         7.       Stock Options.  Upon the occurrence of a Change in Control, 
all stock options shall immediately vest and, except as may be required by the 
nature of the transaction constituting the Change in Control, the options shall 
remain exercisable for the duration of the original option term. If plans or 
agreements to which outstanding options have been issued do not provide for 
immediate vesting, the Company shall use its best efforts to effect amendments 
permitting the acceleration of vesting so long as no material adverse accounting
treatment results to the Company.
         8. Fees and Expenses. The Company agrees that if Employee is entitled
to any severance pay or benefits under this Agreement, and the Company or its
survivor disputes the obligation to pay such severance pay or benefits and the
Employee prevails, in whole or in part, the Company or its survivor shall
promptly pay or reimburse Employee for all expense incurred by Employee in such
dispute, including, but not limited to, attorneys fees and associated expenses.
         9.       Excise Tax Payments.
                  (A) In the event that any payment or benefit (within the
meaning of Section 280G(b)(2) of the Internal Revenue Code of 1986, as amended
(the "Code")), to the Employee or for his benefit paid or payable or distributed
or distributable pursuant to the terms of this Agreement or otherwise in
connection with, or arising out of, his employment with the Company or a change
in ownership or effective control of the Company or of a substantial portion of
its assets (a "Payment" or "Payments"), would be subject to the excise tax

                                       11

<PAGE>


imposed by Section 4999 of the Code or any interest or penalties are incurred by
the Employee with respect to such excise tax (such excise tax, together with any
such interest and penalties, are hereinafter collectively referred to as the
"Excise Tax"), then the Employee will be entitled to receive an additional
payment (a "Gross-Up Payment") in an amount such that after payment by the
Employee of all taxes (including any interest or penalties, other than interest
and penalties imposed by reason of the Employee's failure to file timely a tax
return or pay taxes shown due on his return, imposed with respect to such taxes
and the Excise Tax), including any Excise Tax imposed upon the Gross-Up Payment,
the Employee retains an amount of the Gross-Up Payment equal to the Excise Tax 
imposed upon the Payments.
                  (B) An initial determination as to whether a Gross-Up Payment
is required pursuant to this Agreement and the amount of such Gross-Up Payment
shall be made at the Company's expense by an accounting firm selected by the
Company and reasonably acceptable to the Employee which is designated as one of
the five largest accounting firms in the United States (the "Accounting Firm").
The Accounting Firm shall provide its determination (the "Determination"),
together with detailed supporting calculations and documentation to the Company
and the Employee within ten days of the Termination Date if applicable, or such
other time as requested by the Company or by the Employee (provided the Employee
reasonably believes that any of the Payments may be subject to the Excise Tax)
and if the Accounting Firm determines that no Excise Tax is payable by the
Employee with respect to a Payment or Payments, it shall furnish the Employee
with an opinion reasonably acceptable to the Employee that no Excise Tax will be
imposed with respect to any such Payment or Payments. Within ten days of the
delivery of the Determination to the Employee, the Employee shall have the right
to dispute the Determination (the "Dispute"). The Gross-Up Payment, if any, as
determined pursuant to this Paragraph 9(B) shall be paid by the Company 

                                       12
<PAGE>



to the Employee within five days of the receipt of the Accounting Firm's 
determination. The existence of the Dispute shall not in any way affect the 
Employee's right to receive the Gross-Up Payment in accordance with the 
Determination . Upon the final resolution of a Dispute, the Company shall 
promptly pay to the Employee any additional amount required by such resolution. 
If there is no Dispute, the Determination shall be binding, final and conclusive
upon the Company and the Employee subject to the application of Paragraph 9(C) 
below.
                  (C) Notwithstanding anything in this Agreement to the
contrary, in the event that, according to the Determination, an Excise Tax will
be imposed on any Payment or Payments, the Company shall pay to the applicable
government taxing authorities as Excise Tax withholding, the amount of the
Excise Tax that the Company has actually withheld from the Payment or Payments.
         10.      Successors and Assigns.
                  (A) This Agreement shall be binding upon and shall inure to
the benefit of the Company, its successors, and assigns, and the Company shall
require any successor or assign to expressly assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession or assignment had taken place.
                  (B) Neither this Agreement nor any right or interest hereunder
shall be assignable or transferable by the Employee, his beneficiaries, or legal
representatives except by will or by the laws of dissent and distribution. This
Agreement shall inure to the benefit of and be enforceable by the Employee's
legal personal representative.
         11. Notice. Notice as provided for in this Agreement shall be in
writing and shall be deemed to have been duly given when delivered in person or
mailed by United States Registered Mail, Return Receipt Requested, Postage
Pre-Paid, addressed to the respective 

                                       13

Company. All notices and communications shall be deemed to have been received 
on the date of delivery thereof or on the third business day of the mailing 
thereof, except that notice of change of address shall be effective only upon 
receipt.
         12. Modifications. No provision of this Agreement may be modified,
waived, or discharged unless such modification, waiver, or discharge is agreed
to in writing signed by the Employee and the Company. No waiver by either party
hereto at any time of any breach by the other party hereto of, or compliance
with, any conditional provision of this Agreement to be performed by such other
party shall be deemed a waiver of similar or dissimilar provisions or conditions
of the same at any prior or subsequent time.
         13. Entire Agreement.  No agreement or representations, oral or 
otherwise, express or implied, with respect to the subject matter hereof have 
been made by either party which are not expressly set forth in this Agreement.
         14.      Governing Law.  This Agreement shall be governed by and 
construed and enforced in accordance with the laws of the State of North 
Carolina.
         15.      Severability.  The provisions of this Agreement shall be 
deemed severable and the invalidity or unenforceability of any provision shall 
not affect the validity or enforceability of the other provisions hereof.

Mr. Don Seaquist
5916 Loch Maree Drive
Plano, Texas 75093

Dear Don:

  It is our pleasure to confirm our offer of employment with EMBREX as Vice-
President, Finance & Administration, effective on September 9, 1996, contingent
upon your submitting to and obtaining a negative result from a chemical
screening for drugs and alcohol. Please call Human Resources to schedule your
sample collection. Your starting compensation will be at the rate of $11,250.00
per month.

  Upon commencing employment at EMBREX, you will be entitled to receive an
Incentive Stock Option for 31,500 shares of EMBREX Common Stock at an option
price per share at fair market value on date of grant. These options will vest
equally over four years from the date of grant. This stock option is subject to
the approval and grant by the Compensation Committee of the EMBREX Board of
Directors at their next scheduled meeting.

  Regular, full-time employees of EMBREX are entitled to participate in all
company-sponsored benefit plans. Each plan has terms and conditions regarding
enrollment, which you must discuss with our Human Resources office on your first
day of employment. A booklet describing our current employee benefits and plan
highlights are enclosed for your information. Please review the medical, dental,
LTD and supplemental life plans and make your decision about which plans you
would desire to participate in. Also enclosed is an information package about
our 401(k) retirement savings plan. You are eligible to enroll on your first day
of employment and will need to make several decisions about your employee and
employer investment options, even if you elect not to participate. Please review
the information, complete the enrollment form and beneficiary designation (even
if you elect not to contribute) and bring to your orientation.

  As a relocating employee, and upon presentation of receipts, you will be
entitled to reimbursement for actual and reasonable relocation expenses
including:

  (bullet) Two house (or apartment) hunting trips for you (and your family) not
to exceed 7 days.

  (bullet) Relocation of household effects; and

  (bullet) Temporary living expenses up to 30 days.

  As a homeowner, you are entitled to payments associated with the sale/
purchase as follows:

  (bullet) Real estate and other fees (except discount points, association
fees, prepaid items (escrow), memberships): and

  (bullet) Good faith estimates on closing costs (obtain 2 quotes).

  You are also entitled to a direct incidental cash allowance of $2,000.00,
which is fully taxable. You may submit a check request at any time during the
relocation process, to receive this payment. To offset the anticipated loss on
the sale of your home, we will give you a one-time settlement in the amount of
$15,000.

  Since the Company's relocation policy is a personal arrangement between you
and the Company, you should not discuss it with or make copies of this agreement
available to anyone outside your immediate family.

                       AMENDMENT TO EMPLOYMENT AGREEMENT


     This Amendment to Employment Agreement is made and entered into by Embrex,

Employer and Employee may be collectively referred to as "the parties".

     WHEREAS, the parties entered into an Employment Agreement dated 
8/20/96 (the "Agreement");

    WHEREAS, Employee continues to be employed by Employer; and

    WHEREAS, the parties both desire to amend the prior Employment Agreement
as set forth below.

    NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties agree to amend
their prior Agreement as follows:

    The Agreement is hereby amended by deleting Paragraph 12, Termination
and Liquidated Damages and inserting in lieu thereof the following:

     12. Severance. If Employer terminates Employee's employment under this
     Agreement without cause, then Employee shall be entitled to receive from

     month after termination.

    IN WITNESS WHEREOF, the parties have executed this Amendment to Employment

                               EMBREX, INC.

<PAGE>


                      CHANGE IN CONTROL SEVERANCE AGREEMENT

  THIS CHANGE IN CONTROL SEVERANCE AGREEMENT ("AGREEMENT"), is made and entered
into this 9th day of September, 1996 by and between Embrex, Inc. ("Company"),
a North Carolina corporation, and Don T. Seaquist ("Employee").

  WHEREAS, the Board of Directors ("Board") of the Company considers the
maintenance of a vital management group to be essential in protecting and
enhancing the best interests of the Company and its shareholders;

  WHEREAS, the Board recognizes that the possibility of a Change in Control (as
hereinafter defined) exists and that the threat of or the occurrence of a
Change in Control can result in significant distractions of its key management
personnel because of the uncertainties inherent in such a situation;

  WHEREAS, the Board has determined that it is in the best interest of the
Company and its shareholders to ensure the Employee's continued dedication and
efforts on behalf of the Company; and

  WHEREAS, in order to induce the Employee to remain in the employ of the
Company, particularly in the event of a threat of or the occurrence of a Change
in Control and to dispel any concerns that the Employee may have about taking an
active part in the defense against an inappropriate attempt to bring about a
Change in Control of the Company, the Company desires to enter into this
Agreement with the Employee to provide the Employee with certain payments and
benefits in the event that his employment with the Company is terminated as a
result of, or in connection with, a Change in Control.

  NOW, THEREFOR, in consideration of the mutual agreements herein set forth, the
legal sufficiency and adequacy of which are hereby acknowledged, the parties
agree as follows:

  1. Employment. Employee acknowledges that he is employed with the Company
pursuant to an Employment Agreement dated September 9th, 1996 and hereby agrees
that to the extent any provision of this Agreement should be contrary to any
provision of the Employment Agreement, the terms of this Agreement shall
control.

  2.  Definitions. For purposes of this Agreement, the following terms have the

<PAGE>


meanings indicated:

  (A) "Acquiring Person" shall mean any Person (as such term is hereinafter
defined) who or which, together with all Affiliates (as such term is hereinafter
defined) and Associates (as such term is hereinafter defined) of such Person,
shall be the Beneficial Owner (as such term is hereinafter defined) of
thirty-three percent (33%) or more of the shares of Common Stock then
outstanding, but shall not include (i) the Company, (ii) any Subsidiary of the
Company, (iii) any employee benefit plan or employee stock plan of the Company
or of any Subsidiary of the Company, (iv) any dividend reinvestment plan of the
Company, or (v)any Person or entity organized, appointed, or established by the
Company for or pursuant to the terms of such plan. Notwithstanding the
foregoing, no Person shall become an "Acquiring Person" as the result of an
acquisition of Common Stock by the Company which, by reducing the number of
shares outstanding, increases the proportionate number of shares beneficially
owned by such Person to thirty-five percent (33%) or more of the Common Stock of
the Company then outstanding; provided, however, that if a Person shall become
the Beneficial Owner of thirty-three (33%) or more of the Common Stock of the
Company, then outstanding by reason of such an acquisition and shall, after such
acquisition, become the Beneficial Owner of any additional shares of Common
Stock, then such Person shall be deemed to be an "Acquiring Person." In
addition, notwithstanding the foregoing, if the Board of Directors of the
Company determines in good faith that a Person who would otherwise be an
"Acquiring Person,", as deemed pursuant to the foregoing provisions of this
Paragraph (A), has become such inadvertently, and such Person divests as
promptly as practicable a sufficient number of shares of Common Stock to that
such Person would no longer be an "Acquiring Person" as defined pursuant to the
foregoing provisions of this Paragraph (A), then such Person shall not be deemed
to be an "Acquiring Person" for any purposes of this Agreement.

  (B) "Affiliate" and "Associate" shall have the respective meanings ascribed to
such terms in Rule 12b-2 of the General Rules and Regulations under the
Securities


                                        2
<PAGE>



Exchange Act of 1934, as amended (the "Exchange Act").

  (C) A Person shall be deemed that "Beneficial Owner" of and shall be deemed to
"beneficially own," any securities:

       (i) which such Person or any such Person's Affiliates or Associates,
  directly or indirectly, has the right or obligation to acquire (whether such
  right is exercisable immediately or only after the passage of time) pursuant
  to any agreement, arrangement or understanding (whether or not in writing) or
  upon the exercise of conversion rights, exchange rights, rights, warrants or
  options, or otherwise; provided, however, that a Person shall not be deemed

Reason." For purposes of this Agreement, "Good Reason" shall mean the occurrence
after a Change in Control of any of the following events or conditions:

       (i) a change in the Employee's status, title, position or

(34) equal monthly installments without interest, commencing one month after

benefit programs in which Employee is entitled to participate immediately prior
to the Termination Date provided that Employee's continued participation is
possible under the general terms and provisions of such plans and programs.
Employee's continued participation in such plans and programs shall be at no
greater cost to Employee than the cost he bore for such participation
immediately prior to the Termination Date. If Employee's participation in any
such plan or program is barred, the Company shall arrange upon comparable
terms, and at no greater cost to Employee than the cost he bore for such plans
and programs prior to the Termination Date, to provide Employee with benefits
substantially similar to, or greater than, those which he entitled to receive
under any such plan or program; and

terms of any such plan.

   6. No Duty to Mitigate. Employee shall not be required to mitigate the amount
of any payment provided for in this Agreement by seeking other employment or
otherwise, and no such payment shall be offset or reduced by the amount of any
compensation or benefits provided to the Employee in any subsequent

  7. Stock Options. Upon the occurrence of a Change in Control, all stock
options shall immediately vest and, except as may be required by the nature
of the transaction constituting the Change in Control, the options shall remain
exercisable for the duration of the original option term. If plans or agreements
to which outstanding options have been issued do not provide for immediate
vesting, the Company shall use its best efforts to effect amendments permitting
the acceleration of vesting so long as no material adverse accounting

                                       9

<PAGE>

 treatment results to the Company.

  8. Fees and Expenses. The Company agrees that if Employee is entitled to any
severance pay or benefits under this Agreement, and the Company or its

Employee prevails, in whole or in part, the Company or its survivor shall
promptly pay or reimburse Employee for all expense incurred by Employee in such
dispute, including, but not limited to, attorneys fees and associated expenses.

  9. Excise Tax Payments.

   (A) In the event that any payment or benefit (within the meaning of Section
280G(b)(2) of the Internal Revenue Code of 1986, as amended (the "Code")), to
the Employee or for his benefit paid or payable or distributed or distributable
pursuant to the terms of this Agreement or otherwise in connection with, or
arising out of, his employment with this Company or a change in ownership or
effective control of the Company or of a substantial portion of its assets (a
"Payment" or "Payments"), would be subject to the excise tax imposed by Section
4999 of the Code or any interest or penalties are incurred by the Employee with
respect to such excise tax (such excise tax, together with any such interest and
penalties, are hereinafter collectively referred to as the "Excise Tax"), then
the Employee will be entitled to receive an additional payment (a "Gross-Up
Payment") in any amount such that after payment by the Employee of all taxes
(including any interest or penalties, other than interest and penalties imposed
by reason of the Employee's failure to file timely a tax return or pay taxes
shown due on his return, imposed with respect to such taxes and the Excise Tax),
including any Excise Tax imposed upon the Gross-Up Payment, the Employee retains
an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the
Payments.

   (B) An initial determination as to whether a Gross-Up Payment is required
pursuant to this Agreement and the amount of such Gross-Up Payment shall be made
at the Company's expense by an accounting firm selected by the Company and
reasonably


                                       10

<PAGE>


acceptable to the Employee which is designated as one of the five largest
accounting firms in the United States (the "Accounting Firm"). The Accounting
Firm shall provide its determination (the "Determination"), together with
detailed supporting calculations and documentation to the Company and the
Employee within ten days of the Termination Date if applicable, or such other
time as requested by the Company or by the Employee (provided the Employee
reasonably believes that any of the Payments may be subject to the Excise Tax)
and if the Accounting Firm determines that no Excise Tax is payable by the
Employee with respect to a Payment or Payments, it shall furnish the Employee
with an opinion reasonably acceptable to the Employee that no Excise Tax will be
imposed with respect to any such Payment or Payments. Within ten days of the
delivery of the Determination to the Employee, the Employee shall have the
right to dispute the Determination (the "Dispute"). The Gross-Up Payment, if
any, as determined pursuant to this Paragraph 9(B) shall be paid by the Company
to the Employee within five days of the receipt of the Accounting Firm's
determination. The existence of the Dispute shall not in any way affect the
Employee's right to receive the Gross-Up Payment in accordance with the
Determination. Upon the final resolution of a Dispute, the Company shall
promptly pay to the Employee any additional amount required by such resolution.
If there is no Dispute, the Determination shall be binding, final and conclusive
upon the Company and the Employee subject to the application of Paragraph 9(C)
below.

   (C) Notwithstanding anything in this Agreement to the contrary, in the
event that, according to the Determination, an Excise Tax will be imposed on any
Payment or Payments, the Company shall pay to the applicable government taxing
authorities as Excise Tax withholding, the amount of the Excise Tax that the
Company has actually withheld from the Payment or Payments.

  10. Successor and Assigns.

   (A) This Agreement shall be binding upon and shall inure to the benefit of
the Company, its successors, and assigns, and the Company shall require any
successor or


                                     11

<PAGE>



assign to expressly assume and agree to perform this Agreement in the same
manner and to the same extent that the Company would be required to perform it
if no such succession or assignment had taken place.

   (B) Neither this Agreement nor any right or interest hereunder shall be
assignable or transferable by the Employee, his beneficiaries, or legal
representatives except by will or by the laws of dissent and distribution. This
Agreement shall inure to the benefit of and be enforceable by the Employee's
legal personal representative.

duties hereunder and other duties as (s)he may have to EMBREX.

  8.3 Employee agrees that all such secret information heretofore or hereafter
received will be kept and maintained as confidential and in complete secrecy,
and Employee shall not disclose at any time, either orally or in writing, or
otherwise, in any manner, directly or indirectly, any knowledge or information
Employee has acquired or any trade secret relating to EMBREX or its
subsidiaries, with the exception of disclosure of such information: (i) to
employees of EMBREX who have a need to know it to properly carry out their
duties on behalf of EMBREX and (ii) in the ordinary course of EMBREX business
to customers, suppliers, subcontractors and parties similarly situated.

  8.4 Employee agrees that, while an employee of EMBREX and for two years
thereafter, at least fifteen days before release of publication of any
scientific paper or contributions to periodicals dealing

                                GENERAL PROVISIONS
                             PERSONAL AND CONFIDENTIAL


with or making reference to a subject of interest to EMBREX, Employee will make
available to EMBREX a copy of what is to be published.

9. DELIVERY OF DATA

  Employee agrees to deliver to EMBREX promptly at the termination of employment
or at any other time EMBREX may request, all memoranda, notes, records,
sketches, plans, or other documents which are in Employee's possession or under
his/her control concerning costs, uses, application or purchases of products
made for or by EMBREX ( or any subsidiary, affiliate, or licensee of EMBREX)
or any product, process, formula, or manufacturing method uses, developed,
produced, or investigated by EMBREX (or any subsidiary, affiliate or licensee
of EMBREX), during his/her employment hereunder.

10. INJUNCTIVE RELIEF

  Employee agrees that the remedy at law for any breach of the provisions of
paragraphs 7, 8, and/or 9 of this Agreement will be inadequate and that EMBREX
shall be entitled to injunctive relief in addition to any other remedy they
might have as so ordered by a Court.

11. SEVERABILITY

any portion or portions thereof are held to be invalid, such invalidity shall
not affect the validity of the remaining portion or portions.

  If EMBREX shall terminate the employment of Employee without cause or because
of death, then EMBREX shall be liable to Employee for salary payable pursuant
to 4.1 for one month. No sums shall be due pursuant to any other portion of 4
in the event of termination. The parties agree that this sum is a reasonable
approximation of the actual damages which they presently anticipate would
result from a termination of Employee's employment, and further agree that this
clause is inserted herein not as a penalty but for the sole purpose of avoiding
the difficulty of proof of the actual damages.

13. NOTICES

  All notices, requests, demands, and other communication hereunder shall be
in writing and shall be deemed to have been duly given if mailed by certified
or registered mail, return receipt requested, to the respective parties at

merger, consolidation or other reorganization of EMBREX.

administrators, successors, and assigns, to execute any instruments and to
perform any acts which may be necessary or proper to carry out the purposes
of the Agreement.

North Carolina. The provisions of this Agreement are severable, and in the event

other competent authority shall hold a portion of this Agreement invalid,

                       CHANGE IN CONTROL SEVERANCE AGREEMENT


  THIS CHANGE IN CONTROL SEVERANCE AGREEMENT ("Agreement"), is made and entered
into this 26th day of August, 1996 by and between Embrex, Inc. ("Company"), a
North Carolina corporation, and Rick L. Ryan ("Employee").

  WHEREAS, the Board of Directors ("Board") of the Company considers the
maintenance of a vital management group to be essential in protecting and
enhancing the best interests of the Company and its shareholders;

  WHEREAS, the Board recognizes that the possibility of a Change in Control
(as hereinafter defined) exists and that the threat of or the occurrence of a
Change in Control can result in significant distractions of its key management
personnel because of the uncertainties inherent in such a situation;

  WHEREAS, the Board has determined that it is in the best interest of the
Company and its shareholders to ensure the Employee's continued dedication and
efforts on behalf of the Company; and

  WHEREAS, in order to induced the Employee to remain in the employ of the
Company, particularly in the event of a threat of or the occurrence of a Change
in Control and to dispel any concerns that the Employee may have about taking
an active part in the defense against an inappropriate attempt to bring about
a Change in Control of the Company, the Company desires to enter into this
Agreement with the Employee with certain payments and benefits in the event
that his employment with the Company is terminated as a result of, or in
connection with, a Change in Control.

  NOW THEREFORE, in consideration of the mutual agreements herein set forth,
the legal sufficiency and adequacy of which are whereby acknowledged, the
parties agree as follows:

  1. Employment. Employee acknowledges that he is employed with the Company
pursuant to an Employment Agreement dated August 26th, 1996 and hereby agrees
that to the extent any provision of this Agreement should be contrary to any
provision of the Employment Agreement, the terms of this Agreement shall
control.

  2. Definitions. For purposes of this Agreement, the following terms have the

<PAGE>


meanings indicated:

  (A) "Acquiring Person" shall mean any Person (as such term is hereinafter
defined) who or which, together with all Affiliates (as such term is hereinafter
defined) and Associates (as such term is hereinafter defined) of such Person,
shall be the Beneficial owner (as such term is hereinafter defined) of thirty-
three percent (33%) or more of the shares of Common Stock then outstanding, but
shall not include (i) the Company, (ii) any Subsidiary of the Company,
(iii) any employee benefit plan or employee stock plan of the Company or of any
Subsidiary of the Company, (iv) any dividend reinvestment plan of the Company
or, (v) any Person or entity organized, appointed, or established by the
Company for or pursuant to the terms of such plan. Notwithstanding the
foregoing, no Person shall become an "Acquiring Person" as the result of an
acquisition of Common Stock by the Company which, by reducing the number of
shares outstanding, increases the proportionate number of shares beneficially
owned by such Person to thirty-three percent (33%) or more of the Common Stock
of the Company then outstanding; provide, however, that if a Person shall become
the Beneficial Owner of thirty-three (33%) or more of the Common Stock of the
Company, then outstanding by reason of such an acquisition and shall, after
such acquisition, become the Beneficial Owner of any additional shares of
Common Stock, then such Person shall be deemed to be an "Acquiring Person." In
addition, notwithstanding the foregoing, if the Board of Directors of the
Company determines in good faith that a Person who would otherwise be an
"Acquiring Person," as defined pursuant to the foregoing provisions of this
Paragraph (A), has become such inadvertently, and such Person divests as
promptly as practicable a sufficient number of shares of Common Stock so that
such Person would no longer be an "Acquiring Person" as defined pursuant to the
foregoing provisions of this Paragraph (A), then such Person shall not be
deemed to be an "Acquiring Person" for any purposes of this Agreement.

  (B) "Affiliate" and "Associate" shall have the respective meanings ascribed
to such terms in Rule 12b-2 of the General Rules and Regulations under the
Securities

the exercise of conversion rights, exchange rights, rights, warrants or options,
or otherwise; provided, however, that a Person shall not be deemed the

Section 3(a) or Section 22 of the Rights Agreement (the "Original Rights") or
pursuant to Section 11(i) of the Rights Agreement in connection with an
adjustment made with respect to any Original Rights;

    (ii) which such Person or any of such Person's Affiliates or Associates,

ownership" of (as determined pursuant to Rule 13d-3 of the General Rules and

cluding pursuant to any agreement, arrangement or understanding, whether or not
in writing; provided, however, that a person shall not be deemed the "Beneficial
Owner" of, or to "beneficially own," any security under this subparagraph (ii)
as a result of an agreement, arrangement or understanding to vote such security
if such agreement, arrangement or understanding: (a) arises solely from a
revocable proxy given in response to a public proxy or consent solicitation
made pursuant to, and in accordance with, the applicable provisions of the
General Rules and Regulations under the Exchange Act, and (b) is not also then
reportable by such Person on Schedule 13D under the Exchange Act (or any
comparable or successor report); or

    (iii) which are beneficially owned, directly or indirectly, by any other
Person (or any Affiliate or Associate thereof) with which such Person (or any
of such Person's Affiliates or Associates) has any agreement, arrangement or
understanding (whether or not in writing), but excluding customary agreements
with and between underwriters and selling group members with respect to a bona
fide public offering of securities until the expiration of forty days after the

Acquiring Person, or a representative of an Acquiring Person or of any such
Affiliate or Associate, if such Person's nomination for election or election
to the Board of directors is recommended or approved by a majority of the
Continuing Directors.

  (E) "Person" shall mean any individual, firm, corporation, partnership,
limited liability company or other entity.

  (F) "Subsidiary" shall mean, with reference to any other Person, any

having ordinary voting power, in the absence of contingencies, to elect at
least a majority of the directors or other persons performing similar functions

otherwise controlled by such Person.

  (G) "Termination Date" shall mean the date on which the Employee's employment
with the Company is terminated by the Employee for Good Reason or by the

(taken as a whole) to any Person or Persons other than the Company or any
Subsidiary of the Company).

  4. Termination Following Change in Control. After the occurrence of a Change
in Control, Employee shall be entitled to receive payments and benefits
pursuant to this Agreement if, within two (2) years after the occurrence of a
Change in Control, his employment with the Company is terminated under any of
the following circumstances:

  (A) The Company terminates Employee's employment for reasons other than
"Cause," "Disability," or death. For purposes of this Agreement, "Cause" shall
be defined as:

    (i) the willful and continued failure by Employee to perform substantially
his duties with the Company (other than any such failure resulting from his
Disability) for a significant period of time, after a demand for substantial
performance is delivered to Employee by the Board or a committee thereof, which
specifically identifies the manner in which the Board believes that Employee has
not substantially performed his duties; or

                                       6


<PAGE>


    (ii) the willful engaging by Employee in gross misconduct materially and
demonstrably injurious to the Company. No act, or failure to act, on Employee's
part shall be considered "willful" unless done, or omitted to be done, by
Employee in the absence of good faith and without a reasonable belief that his
action or failure to act was in the best interest of the Company.

  For purposes of this Agreement, "Disability" shall mean a physical or mental
infirmity which impairs the Employee's ability substantially to perform his
employment duties for the Company and which continues for a period of at least
one hundred and eighty (180) consecutive days.

  (B) The Employee terminates his employment with the Company for "Good Reason."
For purposes of this Agreement, "Good Reason" shall mean the occurrence after a
Change in Control of any of the following events or conditions:
    (i) a change in the Employee's status, title, position or responsibilities
(including reporting responsibilities) which, in the Employee's reasonable
judgment, represents an adverse change from his status, title, position or
responsibilities in effect immediately prior thereto; the assignment to Employee
of any duties or responsibilities which in the Employee's reasonable judgment,
are inconsistent with his status, title, position or responsibilities; or any
removal of Employee from or failure to reappoint or reelect him to any of such
positions, status, or title except in connection with the termination of his
employment for Disability, Cause, or death, or by the Employee other than for
Good Reason;

    (ii) a reduction in the Employee's base salary;

    (iii) the Company's requiring the Employee to be based at any place outside
a 30 mile radius from Durham, North Carolina, except for reasonably required
travel on the Company's business which is not greater than such travel
requirements prior to the Change in Control;

                                       7


<PAGE>


    (iv) the failure by the Company to continue in effect any compensation,
welfare or benefit plan in which Employee is participating at the time of a
Change in Control without substituting plans providing Employee with sub-
stantially similar or greater benefits, or the taking of any action by the
Company which would adversely affect Employee's participation in or materially
reduce Employee's benefits under any of such plans or deprive Employee of any
material fringe benefit enjoyed by Employee at the time of the Change in
Control;

    (v) any purported termination of Employee's employment for Cause or
Disability without grounds thereof;

    (vi) the insolvency or the filing (by any party including the Company) of a
petition for bankruptcy of the Company;

    (vii) any material breach by the Company of any provision of this
Agreement; or

    (viii) the failure of the Company to obtain an agreement, satisfactory to
the Employee, from any successor or assign of the Company to assume and agree
to perform this Agreement.

  5. Severance Pay and Benefits. In the event that Employee's employment with
the Company terminates under any of the circumstances described in Paragraph 4
above, Employee shall be entitled to receive all of the following:

  (A) all accrued compensation and any pro-rata bonuses Employee may have
earned up to the Termination Date;

  (B) a severance payment equal to two and nine-tenths (2.9) times the amount
of the Employee's most recent annual compensation, including the amount of his
most recent annual bonus. The severance payment shall be paid in thirty-four
(34) equal monthly installments without interest, commencing one month after
the Termination Date;

                                       8


<PAGE>


  (C) a continuation of benefits. The Company shall maintain in full force and
effect, for two (2) years after the Termination Date, all life insurance,
health, accidental death and dismemberment, and disability plans and other
benefit programs in which Employee is entitled to participate immediately
prior to the Termination Date provided that Employee's continued participation
is possible under the general terms and provisions of such plans and programs.
Employee's continued participation in such plans and programs shall be at no
greater cost to Employee than the cost he bore for such participation
immediately prior to the Termination Date. If Employee's participation in any
such plan or program is barred, the Company shall arrange upon comparable terms,
and at no greater cost to Employee than the cost he bore for such plans and
programs prior to the Termination Date, to provide Employee with benefits
substantially similar to, or greater than, those which he is entitled to
receive under any such plan or program; and

  (D) a lump sum payment (or otherwise as specified by Employee to the extent
permitted by the applicable plan) of any and all amounts contributed to a
Company pension or retirement plan which Employee is entitled to under the
terms of any such plan.

  6. No Duty to Mitigate. Employee shall not be required to mitigate the amount
of any payment provided for in this Agreement by seeking other employment or
otherwise, and no such payment shall be offset or reduced by the amount of any
compensation or benefits provided to the Employee in any subsequent employment.
The severance pay and benefits under this Agreement shall be in lieu of any
other severance pay to which Employee may be entitled from the Company.

  7. Stock Options. Upon the occurrence of a Change in Control, all stock
options shall immediately vest and, except as may be required by the nature
of the transaction constituting the Change in Control, the options shall remain
exercisable for the duration of the original option term. If plans or
agreements to which outstanding options have been issued do not provide for
immediate vesting, the Company shall use its best efforts to effect amendments
permitting the acceleration of vesting so long as no material adverse
accounting

                                       9


<PAGE>


treatment results to the Company.

  8. Fees and Expenses. The Company agrees that if Employee is entitled to any
severance pay or benefits under this Agreement, and the Company or its survivor
disputes the obligation to pay such severance pay or benefits and the Employee
prevails, in whole or in part, the Company or its survivor shall promptly pay
or reimburse Employee for all expense incurred by Employee in such dispute,
including, but not limited to, attorneys fees and associated expenses.

  9. Excise Tax Payments.

  (A) In the event that any payment or benefit (within the meaning of Section
280G(b)(2) of the Internal Revenue Code of 1986, as amended (the "Code")), to
the Employee or for his benefit paid or payable or distributed or distributable
pursuant to the terms of this Agreement or otherwise in connection with, or
arising out of, his employment with the Company or a change in ownership or
effective control of the Company or of a substantial portion of its assets (a
"Payment" or "Payments"), would be subject to the excise tax imposed by Section
4999 of the Code or any interest or penalties are incurred by the Employee with
respect to such excise tax (such excise tax, together with any such interest and
penalties, are hereinafter collectively referred to as the "Excise Tax"), then
the Employee will be entitled to receive an additional payment (a "Gross-Up
Payment") in an amount such that after payment by the Employee of all taxes
(including any interest or penalties, other than the interest and penalties
imposed by reason of the Employee's failure to file timely a tax return or pay
taxes shown due on his return, imposed with respect to such taxes and the
Excise Tax), including any Excise Tax imposed upon the Gross-Up Payment, the
Employee retains an amount of the Gross-Up Payment equal to the Excise Tax
imposed upon the Payments.

  (B) An initial determination as to whether a Gross-Up Payment is required
pursuant to this Agreement and the amount of such Gross-Up Payment shall be
made at the Company's expense by an accounting firm selected by the Company
and reasonably

                                      10


<PAGE>


acceptable to the Employee which is designated as one of the five largest
accounting firms in the United States (the "Accounting Firm"). The Accounting
Firm shall provide its determination (the "Determination"), together with
detailed supporting calculations and documentation to the Company and the
Employee within ten days of the Termination Date if applicable, or such other
time as requested by the Company or by the Employee (provided the Employee
reasonably believes that any of the Payments may be subject to the Excise Tax)
and if the Accounting Firm determines that no Excise Tax is payable by the
Employee with respect to a Payment or Payments, it shall furnish the Employee
with an opinion reasonably acceptable to the Employee that no Excise Tax will
be imposed with respect to any such Payment of Payments. Within ten days of
the delivery of the Determination to the Employee, the Employee shall have the
right to dispute the Determination (the "Dispute"). The Gross-Up Payment, if
any, as determined pursuant to this Paragraph 9(B) shall be paid by the Company
to the Employee within five days of the receipt of the Accounting Firm's
determination. The existence of the Dispute shall not in any way affect the
Employee's right to receive the Gross-Up Payment in accordance with the
Determination. Upon the final resolution of a Dispute, the Company shall
promptly pay to the Employee any additional amount required by such resolution.
If there is no Dispute, the Determination shall be binding, final and
conclusive upon the Company and the Employee subject to the application of
Paragraph 9(C) below.

  (C) Notwithstanding anything in this Agreement to the contrary, in the
event that, according to the Determination, an Excise Tax will be imposed on
any Payment or Payments, the Company shall pay to the applicable government
taxing authorities as Excise Tax withholding, the amount of the Excise Tax that
the Company has actually withheld from the Payment or Payments.

  10. Successors and Assigns.

  (A) This Agreement shall be binding upon and shall inure to the benefit of
the Company, its successors, and assigns, and the Company shall require any
successor or

                                      11


<PAGE>


assign to expressly assume and agree to perform this Agreement in the same
manner and to the same extent that the Company would be required to perform it
if no such succession or assignment had taken place.

  (B) Neither this Agreement nor any right or interest hereunder shall be
assignable or transferable by the Employee, his beneficiaries, or legal
representatives except by will or by the laws of dissent and distribution. This
Agreement shall inure to the benefit of and be enforceable by the Employee's
legal personal representative.

  11. Notice. Notice as provided for in this Agreement shall be in writing and
shall be deemed to have been duly given when delivered in person or mailed by
United States Registered Mail, Return Receipt Requested, Postage Pre-Paid,
addressed to the respective addresses last given by each party to the other,

shall be deemed to have been received on the date of delivery thereof or on the
third business day of the mailing thereof, except that notice of change of
address shall be effective only upon receipt.

  12. Modifications. No provision of this Agreement may be modified, waived, or
discharged unless such modification, waiver, or discharge is agreed to in
writing signed by the Employee and the Company. No waiver by either party
hereto at any time of any breach by the other party hereto of, or compliance
with any conditional provision of this Agreement to be performed by such other
party shall be deemed a waiver of similar or dissimilar provisions or conditions
of the same at any prior or subsequent time.

  13. Entire Agreement. No agreement or representations, oral or otherwise,
express or implied, with respect to the subject matter hereof have been made by
either party which are not expressly set forth in this Agreement.

  14. Governing Law. This Agreement shall be governed by and construed and

                                      12


<PAGE>


enforce in accordance with the laws of the State of North Carolina.

  15. Severability. The provisions of this Agreement shall be deemed severable

SPECIAL CONDITIONS

1   Drawdown
    
    Individual tranches of the loan will be drawn by the borrower in sums of not
    less than $250,000 US. Such drawings may be authorised in writing by a 
    Director of EMBREX EUROPE LTD provided that this authorisation is given in
    accordance with the terms of the Company's account operation mandate 
    current at that time.

    In addition, it is a requirement of the Bank that prior to each individual
    drawdown, the borrower provides the Bank with its written confirmation of 
    the installation of the machinery to which that particular tranche of 
    funding relates, and also details of the specific contract terms.

2   Repayment

    Each individual tranche of funds, once drawn, is to be repaid over four 
    years with equal quarterly repayments of principal being made.

    Interest on each tranche is payable on the quarterly roll-over dates by 
    debit to the borrower's US Dollar Call Account.

3   Fees

    The borrower will pay an arrangement fee equivalent to 0.5% of the amount
    borrowed. The fee will be payable in stages as the individual tranches of 
    the loan are drawn down.

    These arrangement fees will be debited to the borrower's US Dollar Call 
    Account.

4   Interest
  
    Interest will be payable by the borrower at 1% above Barclays three month
    US Dollar Deposit rate applicable at the time of drawdown and subsequent
    roll-over dates. This is dependent upon the Borrower maintaining credit
    balances with Barclays in London in line with security requirements as 
    detailed below, and depositing the funds on fixed three monthly deposits 
    maturing in conjunction with the borrowing so secured. Interest on such 
    deposits will be payable at Barclays three month US Dollar Deposit rate
    applicable at the time the deposit is placed.

<PAGE>

5   Security

    The loan will be secured by:

    a)  US Dollar cash deposits in the name of Barclays Bank re EMBREX EUROPE
        LIMITED provided at the time of, or prior to, drawings of the loan being
        made, in such amounts as to ensure that all borrowings under this
        agreement are 102% covered to allow for interest accrued but not yet 
        paid. These deposits will be placed for a term of three months,
        mirroring the associated borrowing. Any surplus cash deposits made in
        advance of drawings will be initially placed to a US Dollar Call 
        Deposit Account in the name of Barclays Bank PLC re EMBREX EUROPE
        LIMITED.

    b)  Deed of charge over the cash balances referred to above on the Bank's
        standard form to be executed by the Borrower and registered at
        Companies House.

    c)  The Bank requires confirmation from EMBREX INC. that the Deed of Charge
        and the Bank's security interest shall not be affected in any manner
        by any bankruptcy, insolvency, moratorium, assignment for benefit of
        creditors, appointment of a receiver, or any other law or event 
        affecting EMBREX INC, the parent company. Otherwise, the provisions of
        the facility, including without limitation, the Special Conditions and
        the Deed of Charge, shall not apply to Embrex Inc.

We accept the above special terms and conditions which are acknowledged to form
part of the Currency Loan Agreement between EMBREX EUROPE LTD and BARCLAYS BANK
PLC.

For and on behalf of
EMBREX EUROPE LTD

                        BY A CHARGOR FOR OWN LIABILITIES

(If executed by a company this Deed of Charge requires registration at Companies
House within 21 days after its creation).

TO BARCLAYS BANK PLC

1. In consideration of your giving or continuing to give time, credit and/or
   banking facilities and accommodation to me/us, being the party or parties
   named in Schedule 1 hereto, I/we with full title guarantee hereby charge by
   way of first fixed charge all sums of money specified in Schedule 2 hereto
   (the "Deposit(s)" which expression includes all or any part of the money
   payable pursuant to such deposit(s) and the debt(s) represented thereby), 
   together with all interest from time to time accruing thereon, as security
   for the payment of all money and the discharge of all liabilities now or at
   any time hereafter due, owing or incurred to you by me/us (and, if more than
   one, by us jointly or jointly and severally) on any account or accounts 
   or in respect of any obligation howsoever incurred to you by me/us 
   in whatsoever manner and whether actually or contingently and whether alone 
   or together with another or others and whether as principal or 
   surety and in whatsoever name or style, together with interest, 
   discount, commission and all other charges, costs and expenses for 
   which I/we may be or become liable to you ("the Secured Sums").

2. I/we hereby assign to you for the purposes of and to give effect to this
   security my/our right to require you to repay to me/us the Deposit(s) and to 
   pay interest thereon to me/us.

3. I/we agree that during the currency of this security and notwithstanding any
   term (express or implied) pursuant to which any of the Deposit(s) is or may
   be deposited with you or paid to you or held by you, such Deposit(s) shall
   only be repayable upon written request or demand and I/we shall not be 
   entitled to make any request or demand upon you for repayment of such 
   Deposit(s) or for payment of interest thereon, unless you shall first have
   agreed to release this security insofar as it concerns such Deposit(s). Any
   repayment(s) permitted by you shall not be deemed to be a release of this
   security over any other money or interest then or at any time thereafter
   forming part of the Deposit(s) or interest accrued thereon. It is hereby
   expressly agreed that the terms of this security shall override the terms
   applicable to the Deposit(s).

4. (a) You may at any time hereafter enforce this security, without notice to
       me/us and without any further or other consent from me/us, by applying
       or transferring as you think fit all or part of any money or interest
       subject to this security at any time or times (whether on or before or
       after the expiry of any fixed or minimum period for which such money
       may have been deposited) in or towards satisfaction of all or such part
       of the Secured Sums not paid when due.

   (b) You are hereby irrevocably empowered and authorised as my/our attorney in
       my/our name and at my/our expense to execute such documents and give
       such instructions as may be required to give effect hereto, including
       (without limitation) instructions for the withdrawal of any sums which
       you may have placed upon my/our behalf with any third party and for the
       use of any money or interest subject to this security to purchase any
       currency or currencies required to effect such application.

   (c) You shall not be liable for any loss sustained by me/us in consequence
       of the exercise of your rights hereunder, including (without limitation)
       any loss of interest caused by the determination before maturity of any
       Deposit(s) or by the fluctuation in any exchange rate at which currency
       may be bought or sold by you.

5. This security shall be a continuing security notwithstanding any intermediate
   payments or settlement of accounts or other matters whatsoever and shall be 
   in addition to and shall not prejudice or be prejudiced by any rights of set-
   off, combination, lien or other rights exercisable by you as bankers against
   me/us or by any securities, guarantees, indemnities and/or negotiable 
   instruments now or hereafter held by you.

6. I/we shall not assign, transfer, charge or otherwise alienate, deal with or
   encumber any or all of the money or interest subject to this security or 
   my/our right, title or interest therein, or agree so to do.

7. For the avoidance of doubt, I/we agree that this security is to operate by
   way of security only in favour of you and that no release of any 
   indebtedness existing now or in the future from you to me/us is intended
   or effected by this security.

<PAGE>

8. If the persons executing this security are in partnership together and if any
   change shall at any time occur in the composition of the partnership, then,
   unless you decide to close the then current account or accounts of the
   partnership and to open a new account or accounts for the continuing
   partners, this security shall be a continuing security for all liabilities
   incurred to you (after as well as before such change) by the persons for the
   time being constituting such partnership.

9. Deleted. 

10. Where this security is signed by or on behalf of two or more persons, the
    obligations and liabilities of such persons under it shall be joint and
    several. In this security the singular shall include the plural and vice
    versa.

IN WITNESS whereof these presents were executed as a deed this 
day of                    19    .

                                  RISK FACTORS


DEPENDENCE ON CERTAIN CUSTOMERS

         The Company's revenues are highly dependent on expenditures by the
poultry producing industry. The Company's operations could be materially and
adversely affected by a general economic decline in this industry. The Company
has in the past derived, and may in the future derive, a significant portion of
its revenues from a relatively limited number of customers. In 1996, two
customers (Tyson Foods, Inc. and Perdue Farms, Inc.) accounted for approximately
33% and 11%, respectively, of the Company's consolidated revenues. The Company
also has experienced such concentration in the current year and is likely to do
so in future years. The loss of any such customer could materially adversely
affect the Company's revenues.

POSSIBLE NEED FOR ADDITIONAL FINANCING

         From its inception in May 1985 through December 31, 1996, Embrex had
cumulative operating losses (accumulated deficit) of $40.7 million. Until the
first quarter of 1996, Embrex had incurred operating losses since its inception.
Although the Company has been profitable in 1996, there can be no assurance that
Embrex will continue to operate profitably.

         The ability of Embrex to attain revenues sufficient to meet its cash
requirements for operations is dependent upon continued market acceptance of the
INOVOJECT(R) system on lease terms acceptable to Embrex and on the successful
development and commercialization of additional products. The extent of the
Company's future revenues, if any, derived from INOVOJECT(R) fees is subject to
many variables such as whether additional agreements for INOVOJECT(R) systems
are reached, the timing of any agreements, whether existing or new installation
schedules are met, and the extent to which customers use the INOVOJECT(R)
system.

         Until the Company realizes revenues sufficient to satisfy its cash
requirements, it will depend on its current cash and short-term investment
balances and on access to external financing to meet its equipment, working
capital and operating requirements. Although the Company anticipates that its
existing funds, as well as revenues from operations and existing equipment
financing lines, will be sufficient to sustain its existing operations for the
foreseeable future, there are no assurances that such funds will be sufficient.
If additional funds become necessary to sustain existing operations, the Company
will be required to seek additional financing, and there can be no assurance
that such financing will be obtainable or that, if available, such financing
will be on terms favorable or acceptable to the Company. The Company may need
additional financing in order to sustain its anticipated growth, in the event it
does not generate revenues sufficient to satisfy its cash requirements for
future growth. Obtaining additional financing for such purposes may be difficult
or impossible, or financing may only be available on terms unfavorable or
unacceptable to the Company.

EFFECT OF ECONOMIC FACTORS ON REVENUES

         The Company's revenues may be impacted by economic factors that are
beyond the Company's control, such as fluctuations in the price of poultry feed
and export demand for U.S. poultry products. A principal component of the
Company's revenues is fees charged to customers for the number of eggs injected
with the INOVOJECT(R) system. Rising poultry feed prices increase the production
costs of commercial poultry producers and may cause them to reduce production
which, in turn, could adversely impact the Company's revenues. Reduced demand
for U.S. poultry products in markets outside the United States also could impact
the Company's revenues adversely.

                                   1

<PAGE>


NO ASSURANCE OF MARKET ACCEPTANCE OR DEVELOPMENT OF NEW PRODUCTS

         Embrex's principal existing product, the INOVOJECT(R) system, has only
been in full commercial use since 1993. The market acceptance of new
technologies, including those of the Company, is subject to a number of factors,
including the ability of the technology to meet the potential customers' needs
more effectively than competitive products or technologies and any concerns
which may be associated with the use of new technology, such as reliability and
maintenance.

         In addition to the presently marketed INOVOJECT(R) system, Embrex, both
itself and together with collaborators, is developing vaccines for control of
viral and parasitic diseases and products for health and performance
modification which are in various stages of development. These products are
subject to the risks inherent in the development of products based on innovative
technologies and are subject to various regulatory approval requirements.

         Embrex has developed and commercialized a new technology using its
proprietary viral neutralizing factor ("VNF") which permits a single dose
immunization of an egg embryo for the life of the bird. The Company markets a
vaccine known as BURSAPLEX(TM) (formerly known as BDA-Blen) which uses Embrex's
VNF. The vaccine has been approved by the United States Department of
Agriculture ("USDA") for in ovo and post-hatch use. However, BURSAPLEX(TM) has
not yet been accepted in the market and there is no assurance that the product
will be successfully marketed even if it is shown to be effective.

         The development and commercialization of additional new products will
require substantial testing and development and regulatory approval.

GOVERNMENT REGULATION AND NEED FOR REGULATORY APPROVAL

         Although the use of the INOVOJECT(R) system is not subject to
regulatory approval in the U.S., the research and development activities of
Embrex as well as the investigation, manufacture and sale of poultry health and
performance enhancement products are subject to regulation either by the USDA or
the United States Food and Drug Administration ("FDA") and state and foreign
agencies. Foreign agencies may also require approval of the INOVOJECT(R) system.
The process of obtaining governmental approval is costly and at the USDA
generally takes from one to three years and at the FDA five or more years. There
can be no assurance that any future product that Embrex may develop will be
approved by the USDA, the FDA or any other regulatory agency. Delays in
obtaining regulatory approval may adversely affect the marketing of any products
developed by Embrex and the ability of Embrex to receive product revenues and
royalties. There can be no assurance that regulatory approvals for Embrex's
future products will be obtained without lengthy delays, if at all.

         Moreover, Embrex is, or may become, subject to various federal, state
and local laws, regulations and recommendations relating to safe working
conditions, laboratory and manufacturing practices and the use and disposal of
hazardous substances used in conjunction with Embrex's research work. In
addition, Embrex cannot predict the extent of governmental regulations which
might have an adverse effect on the production and marketing of Embrex's
products.

         Embrex has entered into and intends to continue to enter into licensing
or joint development agreements pursuant to which costs associated with the
regulatory approval process for some products are and will be borne by the
licensees or joint developers. To the extent that Embrex is unable to generate
sufficient funds from operations or enter into licensing or joint development
agreements to develop products, it may not have the financial resources to
complete the regulatory approval process with respect to all or any of the
products currently under development. Products developed by Embrex may not be
marketed commercially in any jurisdiction in which required approvals have not
been obtained.

                                       2
<PAGE>


PATENTS AND PROPRIETARY RIGHTS

         Certain of Embrex's products and certain of the processes by which
Embrex is able to produce its products are proprietary. Embrex has ownership
rights to some of the technologies employed in these processes, and some are
owned by others and exclusively licensed to Embrex. Embrex believes that patent
protection of materials or processes it develops and any products that may
result from Embrex's and licensors' research and development efforts are
important to the possible commercialization of Embrex's products. The patent
position of companies such as Embrex generally is highly uncertain and involves
complex legal and factual questions. To date no consistent policy has emerged
regarding the breadth of claims allowed in biotechnology patents. Accordingly,
there can be no assurance that patent applications relating to Embrex's products
or technology will result in patents being issued or that, if issued, the
patents will afford protection against competitors with similar technology.
Moreover, some patent licenses held by Embrex may be terminated upon the
occurrence of certain events or become non-exclusive after a specified period.
In addition, companies that obtain patents claiming products or processes that
are necessary for or useful to the development of Embrex's products could bring
legal actions against Embrex claiming infringement. Embrex is currently not the
subject of any patent infringement claim. There can be no assurance that Embrex
will have the financial resources necessary to enforce any patent rights it may
hold. Also, Embrex may be required to obtain licenses from others to develop,
manufacture or market its products. There can be no assurance that Embrex will
be able to obtain such licenses on commercially reasonable terms or that the
patents underlying the licenses will be valid and enforceable.

         Embrex also relies upon unpatented, proprietary technology, and no
assurance can be given that others will not independently develop substantially
equivalent proprietary information or techniques or properly gain access to
Embrex's proprietary technology, or disclose such technology, or that Embrex can
meaningfully protect its rights in such unpatented proprietary technology.

         Embrex attempts and will continue to attempt to protect its proprietary
materials and processes by relying on trade secret laws and non-disclosure and
confidentiality agreements with its employees and certain other persons who have
access to its proprietary materials or processes or who have licensing or
research arrangements with Embrex. Despite these protections, no assurance can
be given that others will not independently develop or obtain access to such
materials or processes or that Embrex's competitive position will not be
adversely affected thereby.

         In September 1996, Embrex filed an action for patent infringement and
breach of contract against Service Engineering Corp. and a related party. The
infringement action relates to a patent exclusively licensed to Embrex for the
in ovo injection of vaccines into an avian embryo; the breach of contract action
is based on a previous infringement action by Embrex against these parties which
was settled. The defendants have filed counterclaims against Embrex seeking
invalidity of the patent and alleging, among other things, that Embrex violated
federal law by misrepresenting the defendants' commercial activities and sought
to maintain prices for in ovo vaccinations at an artificially high level. The
outcome of this litigation is uncertain and there is no assurance that Embrex
will prevail on the merits or successfully defend the validity of its patent.

         In November 1996, Embrex filed an action for patent infringement
against IGI, Inc. and the same related party, relating to the same patent. The
defendants have asserted various affirmative defenses and denied the substantive
allegations in Embrex's complaint. The outcome of this litigation is uncertain
and there is no assurance that Embrex will prevail on the merits or successfully
defend the validity of its patent.

DEPENDENCE ON KEY PERSONNEL

         Embrex's ability to develop marketable products and maintain a
competitive research and technological position will depend on its ability to
continue to attract and retain experienced and highly educated scientific and
management personnel and advisors. Competition for qualified employees among
biotechnology companies is 

                                       3
<PAGE>


intense and the loss of key scientific or management personnel would adversely 
affect Embrex. Embrex has obtained insurance in the amount of $1,000,000 on the 
life of Randall L. Marcuson, its President and Chief Executive Officer, of 
which Embrex is the sole beneficiary. There can be no assurance that Embrex 
will be able to continue to attract and retain qualified staff.

SUPPORT AND MAINTENANCE REQUIREMENTS

         The Company is required to supply, support, and maintain large numbers
of INOVOJECT(R) systems at its customers' hatcheries on a timely basis at a
reasonable cost to the Company. There can be no assurance that the Company will
be able to continue to provide such services on a cost-effective basis.

TECHNOLOGY AND COMPETITION

         The areas of technology in which Embrex is involved are subject to
rapid and significant technological change. Competitors include independent
companies that specialize in biotechnology as well as major chemical and
pharmaceutical companies, universities, and public and private research
organizations, many of which are well established and have substantially greater
marketing, financial, technological and other resources than Embrex. There can
be no assurance that competitors will not succeed in developing technologies and
products that are more effective than any which have been or are being developed
by Embrex or which would render Embrex's technology and products obsolete or
non-competitive.

DEPENDENCE ON OTHERS

         Embrex plans to continue to conduct its operations with third party
collaborators, licensors or licensees. While Embrex believes its present and
future collaborators, licensors and licensees will have an economic motivation
to succeed in performing their obligations under its agreements with them, the
amount and timing of funds and other resources to be devoted under such
agreements will be controlled by such other parties and are subject to financial
or other difficulties that may befall such other parties. Thus, no assurance can
be given that Embrex will generate any revenues from such agreements.

         Embrex does not have large scale facilities for the production of
Embrex's INOVOJECT(R) system and biological products and does not plan to
develop such facilities in the foreseeable future. Embrex therefore will rely
principally upon relationships with contract manufacturers. There can be no
assurance that manufacture and supply agreements will be maintained on terms and
at costs acceptable to Embrex.

         The Company has developed a strategic relationship with a single
contract manufacturer to fabricate its INOVOJECT(R) systems. While other machine
fabricators exist and have contracted limited numbers of INOVOJECT(R) systems, a
change in fabricators could cause a delay in manufacturing and a possible delay
in the timing of future INOVOJECT(R) installations and revenues from those
installations.

         The Company has granted Select Laboratories, Inc. ("Select"), a
wholly-owned subsidiary of Rhone Merieux SA, exclusive rights to manufacture
bursal disease vaccines containing Embrex's proprietary VNF product for Embrex
to market in North America, South America and Asia. Embrex has also granted
Cyanamid Websters, a subsidiary of American Home Products, Inc., exclusive
rights to manufacture bursal disease vaccines containing the Company's VNF
product to be marketed in Europe, the Middle East and Africa. Additionally, the
Company has two contract suppliers of its VNF product, although only one of
these suppliers was included in the USDA's approval for in ovo use of
BURSAPLEX(TM). The manufacture of the bursal disease vaccines being produced by
Select and Webster and the Company's VNF product generally must be performed in
licensed facilities and/or under approved regulatory methods. Although there are
other manufacturers who are capable of manufacturing bursal disease products and
producing products such as VNF, a change of suppliers could adversely affect the


                                       4

<PAGE>


Company's future operating results due to the time it would take a new supplier
to obtain regulatory approval of its production process and/or manufacturing
facilities.

ISSUANCE OF PREFERRED STOCK; SHAREHOLDER RIGHTS PLAN; ANTI-TAKEOVER EFFECTS

         The Board of Directors has the authority to issue up to 15,000,000
shares of Preferred Stock, no par value per share, in one or more series and to
determine the designations, preferences and relative participating, optional or
other special rights and qualifications, limitations or restrictions thereof, of
the shares constituting any series of Preferred Stock, without any further vote
or action by the shareholders. The issuance of Preferred Stock by the Board of
Directors could affect the rights of the holders of Common Stock. For example,
such issuance could result in a class of securities outstanding that would have
preferences with respect to voting rights and dividends and in liquidation over
the Common Stock, and could (upon conversion or otherwise) enjoy all of the
rights appurtenant to Common Stock.

         The authority of the Board of Directors to issue Preferred Stock could
potentially be used to discourage attempts by others to obtain control of the
Company through merger, tender offer, proxy contest or otherwise by making such
attempts more difficult to achieve or more costly. The Board of Directors may
issue the Preferred Stock without shareholder approval and with voting and
conversion rights which could adversely affect the voting power of the holders
of Common Stock. There are no agreements or understandings for the issuance of
Preferred Stock and the Board of Directors has no present intention to issue any
Preferred Stock.

         In March 1996, Embrex adopted a shareholder rights plan which could
have the effect of discouraging a takeover of the Company. The rights plan, if
triggered, would make it more difficult to acquire the Company by, among other
things, allowing existing shareholders to acquire additional shares at a
substantial discount, thus substantially inhibiting an acquiror's ability to
obtain control of the Company.

INTERNATIONAL SALES AND MARKETING

         The company intends to continue its efforts to expand its markets
outside of North America. Sales outside of North America accounted for
approximately 10%, 6% and 2% of revenues in fiscal 1996, 1995 and 1994,
