                                     PART I

ITEM 1. DESCRIPTION OF BUSINESS.

BUSINESS DEVELOPMENT

         Life Sciences, Inc., a Delaware corporation (the "Company", "LSI" or
"Registrant"), was incorporated in 1963 to produce and sell
specific-pathogen-free, or "SPF", laboratory animals for biomedical research,
particularly in the area of cancer. Since 1990 the Company has primarily focused
its activities on the production and sale of molecular biology enzymes employed
in the synthesis and other manipulations of DNA and other nucleic acids.

         In 1997 the Company ceased production of SPF laboratory animals, and in
1998 shut down a joint venture then engaged in the incineration of biomedical
waste. In 1999 the Company sold an outlying parcel of land to an unaffiliated
neighboring business and, in a separate transaction in May 1999, sold all of its
remaining real estate and entered into a lease for the laboratory and office
facilities it historically occupied. The latter sale transaction satisfied the
$859,075 principal amount of a mortgage on the property and extinguished the
additional mortgage indebtedness secured by the property. The Company also
eliminated in 1999 an additional $568,829 of principal amount of indebtedness
through its conversion into 1,399,927 shares of the Company's Common Stock. In
the mortgage satisfaction transaction and the conversion of debt to equity
transactions, interest and other amounts aggregating approximately $1,100,000
were forgiven and extinguished. The mortgage satisfaction transaction, the lease
transaction, the conversion of debt to equity transactions, and the forgiveness
of indebtedness transactions, were each effected with parties affiliated with
LSI in a restructuring of the Company.

         While revenues during the most recent three fiscal year period
beginning June 1, 1996 went from approximately $660,000 to approximately
$1,084,000, the Company did not have a material operating profit during that
time. Those revenue and additional loans from affiliated parties allowed LSI to
continue in business and to carry out only those activities absolutely essential
to its survival. While the number of Registrant's employees during this time
period remained relatively constant, the mix of employees changed to accommodate
the shift in the emphasis of the Company's business from SPF laboratory animals
to molecular biology enzymes.

BUSINESS OF REGISTRANT

         LSI is a biotechnology company engaged primarily in the production and
sale of enzymes used in the synthesis and manipulation of DNA and other nucleic
acids. The Company specializes in enzyme products employed by scientists to make
genetic (DNA) sequences, which sequences are utilized in basic research and the
genetic modification of plants, animals and other organisms. Genetically
modified organisms provide the basis for production of unique, genetically
engineered drugs, the optimization of certain industrial processes to include
food production, and many other applications.

         For more than 15 years LSI has produced and sold enzymes recovered from
retroviruses, a family of viruses that includes HIV, the causative agent of
AIDS. Specifically the Company propagates large quantities of avian
myeloblastosis virus ("AMV") from which it harvests the enzymes AMV reverse
transcriptase and integrase. Reverse transcriptase causes the synthesis of cDNA
from an RNA template,




                                       3
<PAGE>   4

while integrase catalyzes the cutting of genetic material and is believed to aid
the splicing of retrovirus genes or other foreign DNA into the host's
chromosome.

         In the just ended fiscal year, the Company expanded its production
capability to include the two enzymes of bacterial origin that in combination
with AMV reverse transcriptase are required to carry out nucleic acid
amplification using nucleic acid sequence based amplification ("NASBA"), a
proprietary method for rapid test-tube synthesis of billions of copies of
specific fragments of RNA or DNA. NASBA technology, now owned by Organon
Teknika, a business unit of Akzo Nobel (the Netherlands based chemical and
pharmaceutical giant), and licensed to other diagnostic manufacturers, is
primarily employed in products for assessment of human health to identify the
presence and concentration of viral (virus load) and bacterial pathogens in the
body fluids of patients with diseases such as hepatitis or HIV infection.

         In addition to the sale of enzymes produced in its own facilities, the
Company also sells enzymes produced by others, as well as products that arise
from the combination of enzymes with other substrates into kits used to carry
out certain specific molecular biology reactions. These products include:

         AMV RT CDNA SYNTHESIS KIT - a product designed to maximize the test
         tube synthesis of full-length cDNA to provided an optimal template for
         polymerase chain reaction (PCR) based amplification and other
         experimental techniques; and

         NASBA RESEARCH KIT - a product utilized for nucleic acid amplification
         that is uniquely suited for the amplification of RNA.

         Individuals and organizations engaged in basic genetic research and the
development of genetically engineered products are currently the Company's
primary customers for its enzyme products.

         Registrant currently derives most of its revenue from the sale of AMV
reverse transcriptase and T7 RNA polymerase. When used in combination with the
enzyme RNase-H, these products in proprietary combinations are used to cause the
directed amplification, or copying, of specific segments of RNA or DNA. This
method, along with LSI's enzymes, are employed by the Company and certain of its
customers in the identification of pathogens involved in various human diseases
and their presence as contaminants in water and other materials that may be
ingested by humans.

         The Company sells its molecular biology enzyme products directly to end
users who carry out nucleic acid related research and product development at
universities and diagnostic and pharmaceutical manufacturers, primarily in the
United States and Europe. Direct mail and internet-based communication are
employed in these efforts. The Company also utilizes independent distributors in
Europe and Asia for distribution of its products in those regions of the World.
In addition, the Company sells a significant portion of its enzyme production to
other manufacturers or resellers who either use the product as a component in
kits of their own manufacture, or resell the enzymes in combination with other
substrates to end users. The Company employs four professional scientists and
eight technicians in its enzyme operations.

         Since December 1998, over 40% of the Company's revenues have arisen
from the sale of a special formulation of all of LSI's internally produced
enzyme products to a single clinical diagnostic manufacturer. A supply agreement
currently being negotiated with this manufacturer, Organon Teknika, is expected
to provide that the Company will, until August 2002, supply the enzymes at a
rate about equal to the approximately $400,000 of sales of this product to this
customer during the six months ended July 31, 1999. During the year ended May
31, 1999, the Company was also dependent on a single Asian independent
distributor for an additional 15% of the Company's enzyme revenues for the year.




                                       4
<PAGE>   5

         The Company has begun development of products for rapid detection of
biological contaminants in environment related locations (drinking water and
air), as well as in food and certain samples used to identify the causative
agent of certain human diseases. All of the Company's planned environmental and
clinical diagnostic products for detection of viral or bacterial pathogens are
based on Organon Teknika's NASBA technology. The Company has licensed the NASBA
technology from Organon Teknika for certain specific applications and expects to
reach agreement with other unaffiliated parties to expand the scope of LSI's
NASBA related activities. The NASBA method employs all of the Company's
internally produced enzyme products in conjunction with other substrates to
cause rapid replication (amplification) of specific segments of nucleic acids.
Confirmation of the presence of large numbers of a single segment of RNA or DNA
after the amplification reaction is the basis for determination of the identity
of contaminating viruses or bacteria.

         In 1997, Registrant entered into the first of two agreements with
Innovative Biotechnologies, Inc. ("Innovative"), a Niagara Falls, New York
company, to provided technical and financial support in the development of a
NASBA based test for the waterborne pathogen, Cryptosporidium parvum. This
development effort was successfully completed in the Fall of 1999, and in the
Spring of 2000 the Company expects to begin supplying to Innovative all of the
molecular biology components of the C. parvum test as well as distribution of
the complete test in certain areas of the world. The Company expects to
independently develop additional NASBA based tests for waterborne pathogens.

         The Company executed in June 1999 a letter of intent with 1144668
Ontario Ltd., ("NumberCo"), a Mississauga, Ontario company, that is expected to
enable LSI to produce and sell NASBA based test kits for detection of food borne
pathogens. NumberCo, a successor to Cangene Corp., the original owner of the
NASBA technology, retained a license to utilize NASBA for detection of food
borne pathogens in 1995 when the NASBA related patents and related technology
were conveyed to Organon Teknika. The joint venture of the Company and NumberCo
contemplated by this executed letter of intent is expected to begin operations
in the Summer of 2000 and projects introduction of its first product, a NASBA
based test for Listeria monocytogenes, to the research market in late 2000. The
Company expects to produce and sell additional food borne pathogens tests
developed by the planned joint venture with NumberCo.

         In addition to its enzyme related activities, the Company has continued
its development of a light based analyzer and related sensors for real-time
detection of certain chemicals in the air and in aqueous solutions. This work,
begun more than five years ago with US Department of Energy funding in
conjunction with Lockheed Martin Corp., was slowed in recent years by limited
working capital. However, the Company's activity in this area led to the
February 2000 execution of a letter of intent with Life Sciences, Corp. ("LSC"),
an unaffiliated, Gaithersburg, Maryland company, and Accident Prevention Plus,
LLC ("APP"), a Hauppauge, New York company, to form a joint venture that would
operate state-wide alcohol interlock services initially in the states of Florida
and Georgia. This letter of intent further contemplates the development and sale
of a novel motor vehicle safety related device that combines a breath alcohol
detector based motor vehicle ignition interlock with a motor vehicle data
logger. The proposal anticipates a to-be-completed definitive agreement that,
among other things, is expected to obligate LSC to make available to the
proposed joint venture a breath alcohol analyzer based ignition interlock, as to
which LSC holds an exclusive license for distribution in North America, and a
license to proprietary software that it has developed and currently uses to
support state-wide alcohol interlock programs in 13 states. The contemplated
definitive agreement is similarly expected to obligate APP to grant a license to
the joint venture to utilize APP's proprietary software and related hardware
design for a motor vehicle data logger. The letter of intent provides for equal
holdings in the proposed venture by each of APP, LSC and the Company.




                                       5
<PAGE>   6

         The formation of the proposed joint venture anticipates rapidly
expanding mandated usage of alcohol interlock devices nationwide, as individual
states enact legislation and administrative policies to satisfy certain
requirements related to monitoring of motor vehicle operators with multiple DUI
convictions. Such monitoring or impoundment of vehicles is mandated in
provisions of the U.S. Transportation Equity Act for the 21st Century (TEA 21)
that take effect in October 2000. The potential for successful, rapid extension
of alcohol interlock programs into a large number of states with relatively
modest requirements for capital is enhanced by the combination of the interlock
devices and data logger.

         In addition to applications of the proposed integrated instrument
related to monitoring the breath alcohol level of a motor vehicle operator prior
to starting the vehicle, and from time to time during the course of the
vehicle's operation, the data logger component of the device would monitor and
magnetically store a record of salient parameters associated with the vehicle
performance. Information related to vehicle speed, acceleration and deceleration
rates, engine speed, etc. for over 600 hours of vehicle operation may be stored
on a credit card like device, or communicated in real time to other locations
via modem.

         The participants in the proposed joint venture expect to extend the
range of applications of the integrated data logger / interlock to embrace
monitoring of vehicle operator behavior, including sensors and alarms to detect
and warn of drowsiness.

COMPETITION

         The Company competes with independent laboratories, laboratory product
distributors, clinical diagnostic producers, and non-profit organizations, many
of which are larger and have greater resources than the Company.

         The enzyme segment of the molecular biology industry in which the
Company primarily markets its products is highly fragmented, but includes
several companies with substantially greater financial resources, product
development capabilities and management depth than LSI. Registrant believes its
direct competition in its existing business arises primarily from its
competitors' sale of genetically engineered variants of its major product, AMV
reverse transcriptase, which are sometimes sold at a lower price than the
Company's natural-origin product.

         With respect to its planned environmental and clinical diagnostic
products, the Company will encounter entrenched competition from products that
incorporate the more widely accepted polymerase chain reaction (PCR) method for
amplification of segments of DNA. Vigorous competition is also anticipated in
connection with the proposed joint venture concerning interlock and data logger
devices.

SOURCE AND AVAILABILITY OF MATERIALS

         The principal supplies used in the Company's business consist of
domestic livestock, laboratory plastic ware, glassware, chemicals and animal
feed. Except as described below, these supplies are available from numerous
suppliers, and the Company has experienced no difficulty in purchasing adequate
supplies for its operations. Biological specimens (day old birds) utilized in
the production of the virus substrate from which AMV reverse transcriptase is
derived, are of a specific type and are not widely available. To insulate itself
from disruptions in supply of these birds, LSI has initiated an internal
hatchery operation that enables the Company to sustain its supplies of birds
through the purchase of fertilized eggs from any of 10 hatcheries throughout the
United States. In addition, the Company maintains substantial inventories of the
virus substrate, a portion of which is stored at an off-site, contingent
production facility.




                                       6

PATENTS, TRADEMARKS AND LICENSES

         The Company holds a series of nonexclusive licenses that enable it to
employ a proprietary technology, nucleic acid sequence based amplification
(NASBA), in the production and sale of products for identification of pathogenic
organisms, including biological warfare agents in water, food and air. The NASBA
license regime also permits the Company to produce and sell, in China and Taiwan
only, products for identification of certain viral and bacterial pathogens that
cause a variety of human diseases.

         The Company holds a separate nonexclusive license to produce and sell
products incorporating a proprietary liposome-based technology for rapid, low
cost electrochemical or colorimetric detection and analysis of the outcome of
the nucleic acid amplification events engendered in the NASBA reaction.

         The Company also holds a license to produce and sell a renewable
chemical reagent sensor, the FlowProbe, for real time detection of inorganic and
organic chemical contaminants in water and other aqueous solutions.

         In addition to the foregoing, LSI also holds a concession from the
University of Florida Research Foundation that will permit the Company to
operate a contingent production facility at the Sid Martin Biotechnology Center,
an affiliate of the University of Florida, for emergency production of LSI's
enzyme products using pre-positioned substrates. The availability of a
contingent production facility is expected to be a necessary condition of a
multi-year agreement being negotiated by the Company to supply enzymes for use
in certain clinical diagnostic kits produced by others.

ENVIRONMENTAL MATTERS

         The Company believes it is in compliance with all relevant federal,
state and local environmental regulations, and does not expect to incur
significant costs in the foreseeable future to maintain compliance with such
regulations.

EMPLOYEES

         At May 31, 1999, the Company employed 21 people, including ten
professional employees.

RESEARCH AND DEVELOPMENT

         Product development expenses were $89,284 in 1998 and $118,298 in 1999.
Of these amounts, the majority was applied to the expansion of the Company's
family of enzyme products and the creation of novel formulations of the enzymes
used in the NASBA reaction in order to satisfy the revised requirements of a
major customer. The same enzyme formulations will be used in the NASBA based
diagnostic products that will be produced by the Company. The remaining amounts
were applied in both years to the development of a real time analyzer and
related sensors for real-time detection of chemical contaminants in water and
air.

ITEM 2. DESCRIPTION OF PROPERTY.

         The Company leases a facility of approximately 24,000 square feet at
2900 - 72nd Street North, St. Petersburg, Florida 33710 under the terms of a
five-year lease expiring in 2004. Minimum annual rental under the lease is
$90,000. Until May 1999 the Company owned this property. At that time,
Registrant sold the property to an affiliated entity in satisfaction of the
mortgage indebtedness held by the affiliate on the property. See notes 9 and 10
to Registrant's audited financial statements referred to in Item 7 of this
Amendment No. 1 to Annual Report on Form 10-KSB.

         Registrant's executive and other offices, and its laboratories are
located within these facilities, the majority of which was constructed in 1969
and the balance in 1962. Management believes these facilities are adequate to
meet the needs of the Company's through the end of the lease term.

ITEM 3. LEGAL PROCEEDINGS.

         Registrant is a defendant in an action captioned Imaging Science
Technologies, Inc. v. Life Sciences, Inc., Pinellas County, Florida Circuit
Court Case No. 98-6412-CI-19, which was served on the Company in October 1998.
The complaint seeks unspecified damages based on allegations the Company failed
to hold allegedly confidential information relating to immunobiosensors and
related technology in confidence, failed to return such information to the
plaintiff, and disclosed or used such information for its own purposes. The
Company has denied the material allegations of the complaint. Management of the
Company believes plaintiff's claims are without merit and are immaterial to the
business, operations and prospects of the Company.

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

         No matters were submitted during Registrant's fiscal quarter ended May
31, 1999 to a vote of its stockholders.

$2.00 on April 26, 2000 (the last date prior to the date of this amended report
where a sale of Common Stock was reported on the OTC bulletin board). On April
26, 2000, the closing bid and ask prices for the Common Stock were reported as
$1.50 and $2.00 per share, respectively. The preceding quotations were reported
through market makers or other inter-dealer quotation medium. Those quotations
reflect inter-dealer prices, without retail mark-ups, mark-downs or commissions,

HOLDERS

         At August 19, 1999 and at April 26, 2000 there were approximately 1,200
holders of record of the Common Stock.

DIVIDENDS

         No cash dividends were paid at any time during the Company's two most
recent fiscal years, and the Company does not anticipate or contemplate paying
cash dividends in the foreseeable future. In addition, dividends generally may
only be paid under the laws of the State of Delaware, the place of the Company's
incorporation, out of a corporation's "surplus" (generally the difference
between (i) the total assets of the corporation and (ii) the sum of its total
liabilities, plus the aggregate par value of its outstanding stock), or its net
profits for the fiscal year in which the dividend is declared and/or the
preceding fiscal year. These provisions would be expected to prevent the Company
from paying a dividend at this time.

RECENT SALES OF UNREGISTERED SECURITIES

         The only securities sold by Registrant during the preceding three years
without registration under the Securities Act of 1933, as amended (the
"Securities Act"), were the 1,399,927 shares of Common Stock sold by the Company
in April and May 1999 in two private transactions effected directly by
Registrant with accredited investors and without the payment of any commission.
The Company entered into these transactions with Simon Srybnik, its Chairman and
CEO, a member of Simon Srybnik's family, and business entities wholly owned by
Mr. Srybnik and members of his family.

         Louis D. Srybnik, the brother of Simon Srybnik, agreed in April 1999 to
accept 57,142 shares of Common Stock at $0.4375 per share in payment and
discharge of the $25,000.00 principal amount of a debt due to him. The debt
arose through Louis D. Srybnik's earlier loan to the Company. Interest and other
charges in the amount of approximately $4,300.00 were forgiven or deemed not to
have accrued in the transaction.

         In May 1999 Simon Srybnik and business entities wholly owned by him and
his two brothers, Louis D. and Julius B. Srybnik, agreed to accept an aggregate
of 1,342,785 shares of Common Stock at $0.405 per share in payment and discharge
of the $543,829.39 principal amount of indebtedness represented by various loans
made by them to Registrant over the prior years. Interest and other charges of
approximately $216,770.00 were forgiven or deemed not to have accrued in the
transaction.

         Each of the investors in these two transactions represented to
Registrant that they were accredited investors within the meaning of Regulation
D, as adopted by the Commission under the Securities Act, by virtue of directly
(in the case of the individual investors) or indirectly through their owners (in
the case of the entity investors) meeting the income and/or net worth portions
of the definition of accredited investor within that regulation. The investors
also each made various representations to the Company regarding their investment
intent and sophistication, their knowledge of and access to information
regarding the business and affairs of the Company, and similar matters typical
in such private placement transactions. On the basis of all of the relevant
facts and circumstances, Registrant relied on the provisions of Rule 506 of
Regulation D and/or Section 4(2) of the Securities Act in effecting the
transactions without registration under that act.

ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION.

Introductory Note

         Some of the statements in the following discussion and analysis, and
elsewhere in this Annual Report are "forward-looking statements" and are made
pursuant to the safe harbor provisions of the Private Securities Litigation
Reform Act of 1995. Readers are cautioned that these forward-looking statements
reflect numerous assumptions, known and unknown risks, uncertainties and other
factors that may affect the business and prospects of LSI and cause the actual
results, performance or achievements of the Company to differ materially from
those expressed or implied by the forward-looking statements. These factors
include longer product development lead times, delays in product roll outs,
failure to obtain anticipated contracts with third parties or orders from
customers, or less favorable contracts with third parties or lower than expected
volumes from customers, higher material and labor costs, unfavorable patent or
other technology decisions, the availability of adequate sources of working
capital and cash flow, and economic, competitive, technological, governmental
and other factors. In addition, from time to time the Company may make other
forward-looking statements in future filings (including exhibits) with the
Securities and Exchange Commission, in reports of the Company to its
stockholders, and in other communications made by or with the approval of the
Company.

         Due to the Company's history of operating losses and continued reliance
on loans and advances from related parties, the Company's independent certified
public accountants have qualified their report dated September 8, 1999 on the
Company's financial statements as to a going concern uncertainty. The following
commentary within management's discussion and analysis addresses the Company's
plans with regard to these matters and subsequent events that have a direct
bearing on these matters.

         While revenues from the sale of molecular biology enzymes during fiscal
1999 of $1.08 million were essentially unchanged from the prior year, a
significant shift in the mix of particular enzyme products occurred. The change
reflects the commencement of sales to Organon Teknika, the Netherlands based
manufacturer of clinical diagnostics products, of a novel combination of enzymes
utilized in a proprietary nucleic acid amplification reaction. Until fiscal year
1999, Organon Teknika had purchased only AMV RT from LSI and procured the
remainder of the enzymes required for the NASBA amplification technology from
other vendors. A supply agreement currently being negotiated with Organon
Teknika is expected to commit it to purchase the combination of three enzymes
from LSI until




                                       10
<PAGE>   11

January 2002. The Company currently projects sales of the NASBA enzymes of
slightly less than $1 million for the fiscal year ending May 31, 2000.

         Although the Company's sales to Organon Teknika increased during the
1999 fiscal year, sales to Pacific Rim customers were adversely impacted during
the first half of the fiscal year by generally downward economic trends in Japan
and other countries in the region. Sales to this region rebounded during the
final quarter of the 1999 fiscal year and the Company expects this restored
level to be sustained through fiscal year 2000.

         The cost of sales of enzyme products increased less than $5,000 between
fiscal 1998 and 1999.

         Expenses related to the operating and administrative elements of the
Company's operations increased more than 50% to slightly more than $600,000
between the periods. Significant increases in wages and a portion of the added
amounts for professional expense reflect the costs associated with the sale of
real estate and the recapitalization of the Company through an exchange of debt
held by related parties for equity. Additional expense related to preparations
for an audit of the Company's financial statements for the first time since the
fiscal year ended May 31, 1994. Together these costs exceeded $100,000.
Additional increases in this expense category reflect the Company's increased
attention, manifested in increased travel and communications expense, to its
European and Asian customers who together accounted for more than 65% of fiscal
year 1999 revenue.

         In addition to the costs identified above, additional increases in the
Company's operating and administrative expense arose from a new initiative to
acquire a license to the NASBA technology from Organon Teknika. The Company also
acquired other licenses for complementing proprietary concepts to render the
substrates used in the NASBA reaction thermo stable and to enable rapid
detection of the nucleic acid sequences generated during the NASBA reaction.
When integrated, these innovations are expected to form the technology platform
to support the launch of a family of robust, low-cost, nucleic acid
amplification based tests for detection of pathogens in drinking water, in fresh
and prepared foods, and in applications related to biological weapons defense.

         Further because of the relatively low-cost characteristics of the NASBA
diagnostic tests designed by the Company, a second NASBA license was acquired
from Organon Teknika to enable the Company to produce and sell NASBA based
diagnostic tests for HIV, Hepatitis and other sexually transmitted diseases in
China and Taiwan. The Company believes that a market for these tests exceeding
200 million procedures per year exists in China and adjacent regions. Because
management believes it is essential that a China based joint venture company be
created and separately capitalized in order to achieve the market potential for
NASBA based human diagnostics in this region, the Company incurred significant
related travel, communication and legal expense in connection with the license
negotiations and presentations to potential joint venture partners in the United
States, Japan, China and Taiwan.

         The Company's steps to acquire licenses for NASBA technology and
complementing technologies reflect management's belief that the Company has put
in place the requisite staff and installed the appropriate manufacturing
controls to enable it to supply enzymes to any entity that produces NASBA based
diagnostic kits. The identical resources are expected to be employed to develop
NASBA based diagnostic products for clinical and environmental applications for
LSI's own account. The Company is committed to expansion of its resources to
develop NASBA tests through affiliations and collaborations with business
partners and academic based scientists. Activities in this sphere are expected
to constitute the Company's focus for growth in the intermediate term.

         In addition to the NASBA enzyme mix currently being supplied to Organon
and other NASBA licensees, the Company will begin to produce a dried NASBA
enzyme mix during the fourth quarter of




                                       11
<PAGE>   12

fiscal year 2000. Dried enzymes and other components in NASBA based diagnostic
kits permit the products to be transported and stored in locations where
next-day delivery of frozen products and storage at deep-freeze temperatures may
not be possible. Additionally, the shelf life of new products is extended by the
use of dried test kit components. LSI licensed the enzyme drying technology from
Organon Teknika, and management believes the implementation of the enzyme drying
technology will enhance its currently advantaged position for NASBA enzyme sales
when compared to its competitors.

         The technology used to produce the dried NASBA enzyme mix is equally
effective in protecting any of the nucleic acid modifying enzymes used in
molecular biology research. The availability of dried enzymes for shipment and
short-term storage at ambient temperature is expected to enhance the Company's
ability to market it entire offering of enzyme products to North American end
users, as well as to distributors world wide, particularly those targeting their
sales to the Pacific Rim and Eastern Europe. The availability of dried enzymes
precludes the need for transport of enzyme products using dry ice as a
refrigerant.

         With respect to specific NASBA based environmental diagnostic products,
the Company expects to begin the sale of a NASBA based test for the waterborne
pathogen Cryptosporidium parvum in Autumn 2000 under an agreement with
Innovative Biotechnologies International. While the test kit will be produced by
Innovative, LSI expects to supply all of the molecular biology components of the
test kit, including enzymes, primers and other substrates, while Innovative will
provide the sample collection and sample preparation components together with a
proprietary system and related instrumentation to support analysis of the test
results.

         The Company has executed a letter of intent with 1144668 Ontario Ltd
("NumberCo") to form a joint venture to develop and sell NASBA based test for
detection of food borne pathogens. NumberCo holds a license to employ the NASBA
technology in detection of food-borne pathogens that has its origins in the
invention of the NASBA amplification technology and its subsequent sale to
Organon Teknika. In addition to the license for use of the NASBA technology,
NumberCo owns a completed NASBA based test for detection of Listeria
monocytogenes, a food borne pathogen that was implicated in the FDA mandated
destruction of more than 30 million pounds of prepared foods within the past 12
months. The Company expects to manufacture and sell NumberCo's test for Listeria
monocytogenes.

         To support the planned test for Listeria and other environmental and
clinical diagnostic targets that the Company expects to develop and market, the
Company has acquired via a license from Innovative the identical detection and
analysis technology used with Innovative's test for C. parvum. This detection
system represents a significant advance in the technologies for assessment of
the outcome of nucleic acid amplification and related events. While nearly every
competing method or instrument relies on the examination of emissions of light
from fluorescent or luminescent events, the LSI NASBA tests will rely on the
measurement of low level electrical signals from an electrochemical reaction, or
the detection of changes in color that are machine readable or readily
detectable to the unaided eye. In either version of the technology, the
detection instrument is expected to be market priced at approximately $1,000,
compared to 10 to 50 times that amount for instruments generally used to support
competing nucleic acid detection and analysis technologies. Further, because of
the sensitivity and relative simplicity of the electrochemical detection system,
the time required to carry out the analysis phases of a nucleic acid
amplification reaction can be reduced to approximately 5 minutes compared to the
1 to 2 hours required for some competing methods.

         In December 1999, the Company executed a letter of understanding with
the Centers for Disease Control ("CDC"), an agency of the U.S. government, that
obligates CDC to negotiate solely with LSI on a cooperative research and
development agreement to develop a NASBA based test for detection of
Norwalk-like viruses ("NLV"). This group of food borne pathogens is estimated to
cause approximately




                                       12
<PAGE>   13

23 million cases of food related illness annually in the U.S. The contemplated
agreement is expected to provide for the transfer to the Company of certain U.S.
Government owned intellectual property (patents, patent applications and trade
secrets) related to NLV in exchange for the Company's direct and in-kind funding
to the CDC for development of the test. The Company's effort with the CDC is
focused on the development of tests to support the CDC programs in active and
passive surveillance for food borne pathogens. Because tests used in this manner
are not employed in the diagnosis of human disease, but rather in the
identification of the locus for episodic outbreaks of NLV infections, the
Company believes that it will be able to begin marketing the NLV test without
approvals by the U.S. Food and Drug Administration or other regulatory agencies.
Since the contemplated test for NLV will have applications beyond public health
related surveillance, including clinical diagnosis, the Company expects to enter
into one or more OEM sale arrangements with a major clinical diagnostics
supplier and to jointly seek appropriate regulatory approvals and certifications
after the start of initial sales of the test product. Work on NLV test related
development effort is scheduled to begin in Spring 2000.

         The Company has executed a letter of intent to form a joint venture to
pursue in equal ownership with Life Sciences Corp. (an unrelated entity) and
Accident Prevention Plus the development, operation and/or marketing of alcohol
interlock services and a combination breath alcohol detector based motor vehicle
ignition interlock with a motor vehicle data logger. Certain license rights and
proprietary technologies would be utilized by the proposed joint venture to
participate in an anticipated expansion in federally-mandated usage of alcohol
interlock devices nationwide, as well as expected combinations of the interlock
devices and data logger to perform a variety of functions, including monitoring,
magnetically storing and/or simultaneously transmitting to other locations
records of vehicle performance (e.g., vehicle speed, acceleration and
deceleration rates, engine speed) and monitoring of operator behavior (e.g.,
signs of drowsiness) and related warning alarms.

         The expansion of the Company's product offering to include NASBA based
tests for environmental pathogens, together with the introduction of dried
enzyme preparations and a renewed focus on end-user customers, will require
increases in staff and financial resources allocated to marketing. Additional
staff also will be required to produce increased amounts of molecular biology
enzymes. Management believes that these activities can be readily supported from
projected improvements in the Company's cash flows.

         With respect to product development, the Company is presently seeking a
capital commitment in the range of $6 to $10 million to support the proposed
China joint venture's plan to complete clinical trials in China on a low-cost
virus-load test for HIV before the end of calendar year 2000. Management
believes successful completion of this initial clinical trial will be sufficient
to attract the additional capital required to expand the range of NASBA based
human diagnostic products to be approved by the cognizant regulatory agencies
and offered for sale in China. These additional funds also will be employed to
develop the requisite distribution relations to foster sales of the products
throughout the Chinese subcontinent.

         The Company faces similar challenges with respect to funding the
development of additional diagnostic products for detection of food and water
borne pathogens and biowarfare agents. Management believes development funds
from governmental and private agencies with interests in public health and
alliances with strategic corporate partners will complement the Company's
internally funded development efforts.

         The Company was restructured during fiscal 1999. The Company sold a
parcel of its land to an unrelated party and, in a separate transaction with the
entity holding a mortgage on all the Company's real estate and owned by the
Company's President and Chairman and members of his family, sold its remaining
land together with its office and laboratory facilities. The first transaction
resulted in a gain of approximately $195,000 while




                                       13
<PAGE>   14

the latter, when combined with related forgiveness of accrued interest and of a
related note payable, resulted in an increase in paid-in capital of slightly
more than $1.1 million. In another group of transactions, the Company's Chairman
and President, his brother and related entities agreed to convert existing loans
in the principal amount of $568,829 made by them to the Company into shares of
Common Stock of the Company at the fair market values on the dates of
conversion.

Liquidity and Capital Resources

         During the five years ended May 31, 1999, the Company had operating
losses aggregating $1,695,739, and during those years relied on loans and
advances from related entities to fund its operations. The elimination of
interest for the past two fiscal years, further loans and advances from the
same related entities during that period, and cash from the sale of vacant land
at the end of fiscal 1999 have been the primary sources of working capital to
sustain the Company's operations.

         Net cash used in operating activities in fiscal 1999 was $260,919
compared to $72,421 in fiscal 1998. Net cash in fiscal 1999 was used primarily
to fund the fiscal 1999 operating loss. After taking into account the increase
of $230,382 in accrued interest payable, the net cash in fiscal 1998 was used
mainly to fund the net loss and an almost $200,000 fourth quarter increase in
accounts receivable.

         While the Company's cash needs will increase in fiscal 2000, management
expects that an increase in revenues, improvements in gross margin for certain
of its enzyme products and the elimination of interest expense will assure
sufficient working capital for all of the Company's expanded operations expected
to be internally funded.

         In late calendar 1999, the Company experienced resurgence in enzymes
sales from its Pacific Rim distributors, and at the beginning of fiscal year
2000 a substantial increase in enzyme orders from its most significant customer,
Organon Teknika. Revenues of slightly more than $1.1 million through the end of
the third quarter of fiscal 2000 indicate that total revenues for fiscal year
2000 will exceed 1999 revenues of $1,084,181.

         The Company is pursuing negotiations with respect to a proposed supply
agreement with an expected term of more than two years with respect to supplying
Organon Teknika with the group of enzymes for its nucleic acid amplification
based clinical diagnostic kits. Because LSI would be the sole source supplier of
NASBA enzymes to Organon Teknika, this proposed supply agreement is expected to
be complemented by two additional agreements with Organon Teknika which would be
intended to assure the continuity of Organon Teknika's supply of the NASBA
enzymes. A proposed facilities management agreement and a proposed license
agreement would provide, in essence, that in the event LSI were to be unable to
deliver the NASBA enzymes to Organon Teknika at a scheduled time, Organon
Teknika would, via the provisions of these proposed agreements, advance the
Company approximately $200,000 in cash through a one-time, forward purchase of
substrates used in the production of the AMV reverse transcriptase component of
the NASBA enzyme mix. Under the provisions of these proposed supplemental
agreements, Organon Teknika would also be entitled to directly supervise the
production of the NASBA enzymes in LSI's facilities until LSI were to restore
its capability to make timely delivery of the enzymes. The amounts advanced to
LSI by Organon Teknika would be credited on a prorata basis (with respect to
quantity of enzyme delivered to Organon Teknika in each consignment) against
future deliveries by the Company of the NASBA enzymes to Organon Teknika.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Exchange Act and applicable regulations require
all officers, directors and persons who beneficially own more than 10% of the
Common Stock (collectively, the "Reporting Persons") to file initial reports of
ownership and reports of changes in ownership with the Securities and Exchange
Commission, and to furnish copies to the Company. Specific due dates for these
reports have been established by statute and the Commission. LSI is required to
report herein specified information regarding failures to file such reports on a
timely basis during the most recent fiscal year or prior fiscal years. Based on
its review of available records, the Company believes that all Section 16(a)
filing requirements applicable to the Reporting Persons have been complied with
during LSI's past nine fiscal years, except as shown in the following table.

ITEM 12. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

         During a period of more than five years preceding June 1, 1998, which
date was the beginning of the Company's 1999 fiscal year, various business
entities owned directly or indirectly in equal shares by Simon Srybnik and his
two brothers, Louis D. and Julius B. Srybnik, and Simon Srybnik and Louis D.
Srybnik individually, provided various loans in amounts that were required, when
combined with the limited revenues of LSI during the period, to allow LSI to
continue in business and to carry out only those activities absolutely essential
to its survival. Simon Srybnik is a director of the Company, a nominee for
re-election as a director of the Company, and is the Company's Chairman, Chief
Executive Officer and President. He and his two brother may be considered to be
the "parents" of LSI within the meaning of the Exchange Act by virtue of their
direct and indirect beneficial ownership of LSI Common Stock. See the tabular
information and related notes set forth in Item 11 of this Amendment No. 1 to
Annual Report on Form 10-KSB.

     While there may have been some upward and downward fluctuations in the
total amounts due to these affiliated parties during the period, from May 31,
1993 to May 31, 1998 the aggregate amount of the indebtedness to these related
parties, including interest and other charges, increased from approximately
$707,000 to approximately $2,425,000. The rates of interest on these loans
during this period was typically between 10.5% and 11.5%, and was 10.5% during
fiscal 1998. No interest accrued on this debt subsequent to May 31, 1998. During
fiscal 1998, the aggregate amount of this related party indebtedness increased
by approximately $186,648 to reach the total of approximately $2,425,000 at May
31, 1998. In the fiscal year ended May 31, 1999, the principal of this
indebtedness increased by $103,165 (net). All of this indebtedness was
eliminated through restructuring transactions between the Company and these
related parties in fiscal 1999.




                                       19
<PAGE>   20

         Approximately $905,000 of the total of this indebtedness was eliminated
through the conversion in April and May 1999 of a total of $568,829 of principal
into 1,399,927 shares of the Company's Common Stock and the forgiveness by the
creditors of the balance. Louis D. Srybnik agreed in April 1999 to accept 57,142
shares of Common Stock at $0.4375 per share in payment and discharge of the
$25,000.00 principal amount of a debt due to him in connection with his earlier
loan to the Company. In May 1999 Simon Srybnik and certain of the business
entities controlled by him and his two brothers (Kerns Manufacturing Corp.,
Industrial Renting Corp., Continental Salvage Corp., Sutton Investing Corp., S&S
Machinery Corp., and Apex Organization, Inc.) agreed to accept an aggregate of
1,342,785 shares of Common Stock at $0.405 per share in payment and discharge of
the $543,829.39 aggregate principal amount of indebtedness represented by
various separate loans made by them to LSI over the prior years. Interest and
other charges due on these debts were forgiven in these stock issuance
transactions. The prices at which the shares were issued in these transactions
were each equal to the approximate mean between the last available reported bid
and ask prices of the Common Stock in the over-the-counter market prior to the
respective dates of the transactions. Kerns Manufacturing Corp. was a more than
10% beneficial owner of the Common Stock prior to the May 1999 transaction and
increased its ownership through it, and Sutton Investing Corp. became a more
than 10% beneficial owner of the Common Stock through that transaction.

         Also in May 1999, the Company sold an outlying parcel of its land to an
unaffiliated neighboring business for $200,000 cash. In a separate transaction
on the same day with a related business entity, the Company sold all of its
remaining real estate and entered into a lease for the laboratory and office
facilities it historically owned and occupied. The latter sale transaction
satisfied $859,075 of the principal amount of a mortgage on the property and,
via forgiveness of interest and other amounts, extinguished an additional
approximately $764,000 of real estate related indebtedness. The Company's
aggregate historical cost from the 1960's of all of the land and building
improvements was less than $500,000. The aggregate of the sales prices in these
two real estate sale transactions was slightly greater than an appraisal secured
about a year earlier of the entire property. The mortgage satisfaction real
estate transaction and the lease transaction were effected with 186-194 Imlay
Street Realty Corp. ("Imlay Street Realty"), one of the business entities
equally owned by Simon, Louis D. and Julius B. Srybnik.

         Imlay Street Realty leases the laboratory and office facilities of the
Company to the Company under a five year lease expiring in 2004. The lease of
the approximately 24,000 facility in St. Petersburg, Florida provides for an
annual rental for the initial two years of $90,000. The rent is subject to
adjustment each two years thereafter to reflect current market rental rates, but
not less than the initial rate.

         As described in the text following the caption "Option Grants in Last
Fiscal Year" under Item 10 of this Amendment No. 1 to Annual Report on Form
10-KSB, the Company granted Alex A. Burns, an executive officer of LSI, a
nominee for election as a director of the Company and the beneficial owner of
more than 5% of the Common Stock, options covering 350,000 shares of Common
Stock in fiscal 1999. As indicated in that text, these options were granted with
an option exercise price of not less than 100% of the fair market value of the
underlying Common Stock on the date of the grants.

                                                              Exhibit 10.1

                        1988 EMPLOYEE STOCK OPTION PLAN
                                       OF
                              LIFE SCIENCES, INC.


         1.       THE PLAN. This 1988 Employee Stock Option Plan (the "Plan")
is intended to encourage ownership of stock of Life Sciences, Inc. (the
"Corporation") by specified employees of the Corporation and its subsidiaries
and to provide additional incentive for them to promote the success of the
business of the Corporation.

         2.       STOCK SUBJECT TO THE PLAN. Subject to the provisions of
Paragraph 14 hereof, the total number of shares of the common stock, par value
$.10 per share, of the Corporation (the "Stock") which may be issued pursuant
to incentive stock options and non-incentive stock options granted under the
Plan (the "Options") shall not exceed 250,000. Such shares of Stock may be, in
whole or in part, either authorized and unissued shares or treasury shares, as
the Board of Directors of the Corporation (the "Board") shall from time to time
determine. If an Option shall expire or terminate for any reason without having
been exercised in full, the unpurchased shares covered thereby shall (unless
the Plan shall have been terminated) again be available for Options under the
Plan.

         3.       ADMINISTRATION OF THE PLAN. The Plan shall be administered by
the Board which shall have plenary authority, in its discretion, to determine
the employees of the Corporation and its subsidiaries to whom Options shall be
granted (individually, an "Optionee," and collectively, the "Optionees"), the
number of shares to be subject to each Option and the terms of each Option. The
Board shall also have plenary authority, subject to the express provisions of
the Plan, to interpret the Plan, to prescribe, amend and rescind any rules and
regulations relating to the Plan and to take such other action in connection
with the Plan as it deems necessary or advisable. The interpretation and
construction by the Board of any provisions of the Plan or of any Option
granted thereunder shall be final, and no member of the Board shall be liable
for any action or determination made in good faith with respect to the Plan or
any Option granted thereunder.

         4.       EMPLOYEES ELIGIBLE FOR OPTIONS. All employees of the
Corporation or its subsidiaries shall be eligible for Options. In making the
determination as to employees to whom Options shall be granted and as to the
number of shares to be covered by such Options, the Board shall take into
account the duties of the respective employees, their present and potential
contributions to the success of the Corporation, and such other factors as it
shall deem relevant in connection with accomplishing the purposes of the Plan.

         5.       TERM OF PLAN. The Plan shall terminate on, and no Options
shall be granted after, October 1, 1998, provided that the Board may at any
time terminate the Plan prior thereto.


<PAGE>   2

         6.       MAXIMUM OPTION GRANT. The aggregate fair market value
(determined as of the time the Option is granted) of the Stock of the
Corporation, with respect to which incentive stock options are exercisable for
the first time by an employee during any calendar year (under this Plan or any
other plan of the Corporation or the parent or any subsidiary of the
Corporation), shall not exceed $100,000.

         7.       OPTION PRICE. Each Option shall state the option price, which
shall be not less than 100% of the fair market value of the Stock on the date
of the granting of the Option. The fair market value of shares of Stock shall
be determined by the Board and shall be the mean between the bid and ask prices
of the Stock in the over-the-counter market on the date of the granting of the
Option. Notwithstanding any other provision contained in this Plan, an Option
granted to an employee who, on the date of grant, owns stock possessing more
than 10% of the total combined voting power of all classes of stock of either
the Corporation or any parent or subsidiary, shall be granted at an option
price of 110% of fair market value on the date of grant and shall be
exercisable only during the five-year period immediately following the date of
grant. In calculating stock ownership of any person, the attribution rules of
Code ss. 425(d) will apply. Furthermore, in calculating stock ownership, any
stock that the employee may purchase under outstanding options will not be
considered.

         8.       TERM OF OPTIONS. The term of each Option shall be for a
maximum of ten years from the date of granting thereof, but may be for a lesser
period or be subject to earlier termination as hereinafter provided.

         9.       EXERCISE OF OPTIONS. Any Option may be exercised from time to
time as to any part or all of the Stock to which the Optionee shall then be
entitled, provided, however, that an Option may not be exercised (a) as to less
than 100 shares at any one time (or for the remaining shares then purchasable
under the Option, if less that 100 shares), and (b) unless the Optionee shall
have been in the continuous employ of the Corporation or its subsidiaries from
the date of the granting of the Option to the date of its exercise, except as

in cash, or (ii) by the transfer to the Corporation of shares of its Stock with
a fair market value (as determined by the Board) equal to the purchase price of
the Stock issuable upon exercise of such Option. The holder of an Option shall

exercise of an Option until certificates for such Stock shall have been
delivered to him after the exercise of the Option.

         10.      NON-TRANSFERABILITY OF OPTIONS. An Option shall not be

shall deem appropriate.

         12.      TERMINATION OF EMPLOYMENT. In the event that the employment
of an Optionee shall be terminated (otherwise than by reason of death), such
Option shall be exercisable (to the extent that the Optionee shall have been
entitled to do so at the termination of his employment) at any time before the
expiration of a period of time not exceeding three months after such
termination, but not more than ten years after the date on which such Option
shall have been granted. Nothing in the Plan or in the Option Agreement shall
confer upon any Optionee any right to be continued in the employ of the
Corporation or its subsidiaries, or to interfere in any way with the right of
the Corporation or any such subsidiary to terminate or otherwise modify the
terms of Optionee's duties or position shall not affect such Optionee's Option
so long as such Optionee is still an employee of the Corporation or its
subsidiaries.

         13.      DEATH OF EMPLOYEE. In the event of the death of an Optionee,
any unexercised Option shall be exercisable (to the extent that the Optionee
shall have been entitled to do so at the time of his death) at any time before

more that ten years after the date on which such Option shall have been
granted, and only by such person or persons to whom such deceased Optionee's
right shall pass under such Optionee's will or by the laws of descent and
distribution.

         14.      ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. In the event of
changes in the outstanding Stock of the Corporation by reason of stock
dividends, split-ups, capitalization, mergers, consolidations, combinations or
exchanges of shares, reorganizations or liquidations, the number and class of
shares available under the Plan and the maximum number of shares as to which
Options may be granted to an employee shall be correspondingly adjusted.

         15.      SHAREHOLDER APPROVAL. This Plan is subject to, and no Options
shall be exercisable hereunder until after, the approval of the Plan by a
majority of the outstanding Stock of the Corporation within twelve months after
the date of the adoption of the Plan by the Board.

         16.      AMENDMENT OF THE PLAN. The Board shall have complete power
and authority to modify or amend the Plan (including the form of Option
Agreement) from time to time in such respects as it shall deem appropriate,
provided, however, that the Board shall not, without the approval of a majority
of the outstanding Stock of the Corporation entitled to vote at a meeting of
the stockholders, (I) increase the maximum number of shares which in the
aggregate are subject to Options under the Plan except as set forth in
Paragraph 14, (ii) extend the period during which Options may be granted or
exercised, or (iii) reduce the Option price below 100% of the fair market value
of the Stock issuable upon exercise of Options at the time of the granting
thereof, other than to change the manner of determining the fair market value
thereof. No termination or amendment of the Plan shall, without consent of the
individual Optionee, adversely affect the right of such Optionee under an
Option theretofore granted to him or under such Optionee's Option Agreement.

                        1990 EMPLOYEE STOCK OPTION PLAN
                                       OF
                              LIFE SCIENCES, INC.

         1.       THE PLAN: This 1990 Employee Stock Option Plan (the "Plan")
is intended to encourage ownership of stock of Life Sciences Inc. (the
"Corporation") by specified employees of the Corporation and its subsidiaries
and to provide additional incentive for them to promote the success of the
business of the Corporation.

         2.       STOCK SUBJECT TO THE PLAN: Subject to the provisions of
Paragraph 14, the total number of shares of the Common Stock, par value $.10
per share, of the Corporation (the "Stock") that may be issued pursuant to
incentive stock options [within the meaning of the Internal Revenue Code of
1986, as amended, (the "Code")], and non-incentive stock options granted under
the Plan (the "Options") shall not exceed 500,000. The Stock may be, in whole
or in part, either authorized and unissued shares or treasury shares as the
Board of Directors of the Corporation (the "Board") shall from time to time
determine. If an Option shall expire or terminate for any reason without having
been exercised in full, the unpurchased shares covered thereby shall (unless
the Plan shall have been terminated) again be available for Options under the
Plan.

         3.       ADMINISTRATION OF THE PLAN: The Plan shall be administered by
the Board which shall have plenary authority, in its discretion, to determine
the employees of the Corporation and its subsidiaries to whom Options shall be
granted (individually, an "Optionee," and collectively, the "Optionees"), the
number of shares of Stock to be subject to each Option, and the terms of each
Option, including whether it is intended to be an incentive stock option, a
non-incentive stock option, or both. The Board shall also have plenary
authority, subject to the express provisions of the Plan, to interpret the
Plan, to prescribe, amend and rescind any rules and regulations relating to the
Plan, and to take such other action in connection with the Plan as it deems
necessary or advisable. The interpretation and construction by the Board of any
provisions of the Plan or of any Option granted thereunder shall be final, and
no member of the Board shall be liable for any action or determination made in
good faith with respect to the Plan or any Option granted thereunder.

         4.       EMPLOYEES ELIGIBLE FOR OPTIONS: All employees of the
Corporation or its subsidiaries shall be eligible for Options. In making the
determination as to employees to whom Options shall be granted and as to the
number of shares of Stock to by covered by such Options, the Board shall take
into account the duties of the respective employees, their present and
potential contributions to the success of the Corporation, and such other
factors as it shall deem relevant in connection with accomplishing the purposes
of the Plan.

         5.       TERM OF PLAN: The Plan shall terminate on, and no Options
shall be granted after, December 12, 2000 provided, however, the Board may at
any time terminate the Plan prior thereto, subject to the last sentences of
Paragraph 16.

         6.       MAXIMUM OPTION GRANT: The aggregate fair market value
(determined as of the time of the Option granted) of Stock with respect to
which incentive stock options are exercisable for the first time by an Optionee
during any calendar year (under this Plan or any other plan of the Corporation
or the parent or any subsidiary of the Corporation) shall not exceed $100,000.

         7.       OPTION PRICE: Each Option shall state the option price, which
shall be not less than 100% of the fair market value of the Stock on the date
of the granting of the Option. The fair market value of the Stock shall be
determined by the Board and shall be the mean between the bid and ask prices of
the Stock in the over-the-counter market on the date of the granting of the
Option. Notwithstanding any other provision contained in this Plan, an Option
granted to an employee who, on the date of grant owns voting securities
possessing more than 10% of the total combined voting power of all classes of
shares of either the Corporation or any parent or subsidiary, shall be granted
at an option price of not less than 110% of fair market value on the date of
grant, and shall be exercisable only during the five-year period immediately
following the date of grant. In calculating ownership of shares of any person,
the attribution rules of Code, Section 425(d), will apply. Furthermore, in
calculating share ownership, any shares the Optionee may purchase under
outstanding options will not be considered.



                                  Page 1 of 3

<PAGE>   2

         8.       TERM OF OPTIONS: The term of each Option shall be for a
maximum of ten years from the date of granting thereof, but may be for a lesser
period or be subject to earlier termination as hereinafter provided.

         9.       EXERCISE OF OPTIONS: Any Option may be exercised from time to
time as to any part or all of the Stock to which the Optionee shall then be
entitled; provided, however, an Option may not be exercised (a) as to less than
100 shares at any one time (or for the remaining shares then purchasable under
the Option if less than 100 shares), (b) unless the Optionee shall have been in
the continuous employ of the Corporation or its subsidiaries from the date of
the granting of the Option to the date of its exercise, except as provided in
Paragraphs 12 and 13, and (c) an incentive stock option may not be exercised
while any previously granted incentive stock option is outstanding. The
purchase price of the Stock issuable upon exercise of an Option shall be paid
in full at the time of exercise thereof (i) in cash, or (ii) by the transfer to
the Corporation of shares of Stock with a fair market value (as determined by
the Board) equal to the purchase price of the Stock issuable upon exercise of
such Option. The holder of an Option shall not have any rights as a stockholder
with respect to the Stock issuable upon exercise of an Option until
certificates for such Stock shall have been registered in the name of the
Optionee after the exercise of the Option.

         10.      NON-TRANSFERABILITY OF OPTIONS: An Option shall not be
transferable otherwise than by will or the laws of descent and distribution,
and is exercisable during the lifetime of the Optionee only by the Optionee.

         11.      FORM OF OPTION: Each Option granted pursuant to the Plan
shall be evidenced by an agreement (an "Option Agreement") in such form as the
Board shall from time to time approve. The Option Agreement shall comply in all
respects with all the terms and conditions of the Plan and the requirements of
the Code, and may contain such additional provisions, including, without
limitation, restrictions upon the exercise of the Option, as the Board shall
deem advisable.

         12.      TERMINATION OF EMPLOYMENT: In the event the employment of an
Optionee shall be terminated (otherwise than by reason of death), any Option
held by such Optionee shall be exercisable (to the extent the Optionee shall
have been entitled to do so at the termination of his employment) at any time
prior to the expiration of three months after such termination, but not more
than ten years after the date on which such Option shall have been granted.
Nothing in the Plan or in the Option Agreement shall confer upon any Optionee
any right to be continued in the employ of the Corporation or its subsidiaries
or interfere in any way with the right of the Corporation or any such
subsidiary to terminate or otherwise modify the terms of an Optionee's
employment; provided, however, a change in an Optionee's duties or position
shall not affect such Optionee's Option so long as such Optionee is still an
employee of the Corporation or its subsidiaries.

         13.      DEATH OF EMPLOYEE: In the event of the death of an Optionee,
any unexercised portion of his Option shall be exercisable (to the extent the
Optionee shall have been entitled to do so at the time of his death) at any
time before the expiration of three months after his death, but not more than
ten years after the date on which such Option shall have been granted, and only
by such person or persons to whom such deceased Optionee's rights shall pass
under such Optionee's will or by the laws of descent and distribution.

         14.      ADJUSTMENTS UPON CHANGES IN CAPITALIZATION: In the event of
changes in the outstanding Stock by reason of any stock dividends, split-ups,
capitalizations, mergers, consolidations, combinations or exchanges of shares,
reorganizations or liquidations, the number and class of shares available under
the Plan and the maximum number of shares as to which Options may be granted to
Optionees under outstanding Option Agreements shall be correspondingly
adjusted.

         15.      SHAREHOLDER APPROVAL: This Plan is subject to, and no Options
shall be exercisable hereunder until after, the approval by a majority of the
outstanding Stock of the Corporation within twelve months after the date of the
adoption of the Plan by the Board.

         16.      AMENDMENT OF THE PLAN: The Board shall have complete power
and authority to modify or amend the Plan (including the form of Option
Agreement) form time to time in such respects as it shall deem appropriate;
provided, however, the Board shall not, without the approval of a majority of
the outstanding Stock entitled to vote at a meeting of the stockholders, (i)
increase the maximum number of shares of Stock which in the aggregate are
subject to Options under the Plan except as set forth in Paragraph 14, (ii)
extend the period during which Options may be granted or exercised, or (iii)
reduce the Option price below 100% of the fair market value of the Stock
issuable upon exercise of Options at the time of the granting thereof, other
than to change the manner of determining the fair market value thereof. No
termination or amendment of the Plan shall, without the consent of the
individual Optionee, adversely affect the rights of such Optionee under an
Option theretofore granted to him or under such Optionee's Option Agreement.

3.       Royalties, Records and Accounting

3.1      In consideration of the rights granted under Article 2, LICENSEE shall

         Agreement a non-refundable, non deductible payment of USD 300,000 {US
         Dollars three hundred thousand}, which payment shall not act as prepaid
         royalties creditable toward any running royalties due under this
         Paragraph as and when such royalties are due and payable.

3.2      Furthermore LICENSEE shall pay Teknika as from the Effective Date
         hereof, a running royalty of 8% of the Net Sales to end-users of
         Licensed Products utilizing NASBA Technology. The LICENSEE shall pay
         Teknika a running royalty of 10% of the Net Sales to resellers for

         royalty of 3% of the Net Sales for Licensed Products utilizing Boom

         resellers. Royalties due on sales of Licensed Products made during the
         periods prior to the LICENSEE achieving annual sales of USD 5 million
         of the Licensed Products may be offset by license fees payable to the
         LICENSEE by Teknika for Teknika's access to trade secrets or other
         intellectual property developed by the LICENSEE and its affiliates. The
         election to license such trade secrets or intellectual property is to
         be made at Teknika's sole discretion. The LICENSEE's anticipated
         integrated NASBA cassette shall be excluded from the technologies made
         available to Teknika via this construction.

         of account in accordance with good accounting practice, showing the
         information required to permit calculation of Net Sales and the
         royalties under this Article. These books and records shall be
         preserved for at least six {6} years from the date of the royalty
         payments to which they pertain.

3.4      On or before the 45th day of each calendar quarter during the term
         hereof LICENSEE shall prepare and send to Teknika royalty reports for
         the previous quarter. Said reports shall indicate total sales and Net
         Sales per country under this Agreement for the previous calendar
         quarter, per Licensed Product, and shall show the amount of royalty due
         with sufficient information to enable confirmation by Teknika, and
         LICENSEE shall include payment of the amount of royalties shown to be
         due with such report.




<PAGE>   4

3.5      Periodically {i.e., each calendar quarter}, LICENSEE shall provide to
         Teknika customer lists, enabling Teknika to closely follow-up and keep
         track of which customers are being served by LICENSEE.

3.6      Upon ten (10) days written notice and not more than once per calendar
         year, LICENSEE agrees to permit one or more Certified Public Account
         {s} appointed by Teknika {except one to whom LICENSEE has a reasonable
         objection}, to enter upon the premises of LICENSEE during all usual
         business hours of LICENSEE at any time following the 60th day of any
         calendar quarter in order to inspect files and records pertaining to
         Net Sales and royalties under this Agreement, and to make on LICENSEE's
         premises and retain copies of any and all parts of the records and
         accounts kept by LICENSEE pursuant to this Article, including invoices
         which are relevant to any reports required to be rendered by LICENSEE.

3.7      Said copies shall be provided to the Certified Public Accountant {s} at
         no expense to Teknika. Said Certified Public Accountant {s} shall keep
         all information received from LICENSEE confidential; however, it will
         provide Teknika with the Net Sales, per country, for each type of
         Licensed Product, specifying the sales and the application of the
         appropriate royalty rate so that royalties due Teknika may be
         calculated. The information obtained by the Certified Public Accountant
         {s} shall be retained for a period of seven {7} years.

         In the event any audit results in a change upward in any royalty
         payment of as much as five percent {5%} for any annual period, LICENSEE
         shall pay the costs of such audit for such annual period, otherwise
         such audit shall be at Teknika's expenses.

3.7      Payment of all royalties hereunder shall be made at Teknika's option in
         Dutch Guilders or Euro at the mean rate of exchange existing on the
         last day of the quarter to which the payment applies as published in
         the Wall Street Journal {European Edition}.

         Date} and shall remain in effect until the last to expire of the Patent

         default may terminate this Agreement by written notice. Such
         termination shall become effective on the date set forth in the notice
         of termination, but in no event shall it be earlier than sixty (60)
         days from the date of mailing

         the said period of notice.

         obligation to pay Teknika all royalties that shall have accrued up to
         the effective date of termination.

5.       Assignment

         Teknika shall have the right to assign this Agreement to, or delegate
         its obligations hereunder to be performed by any successor or
         Affiliated Company of Teknika, provided that Teknika warrants that the
         terms and conditions for LICENSEE remain unchanged. This Agreement is

St. Petersburg, Florida 33710

         Re:      Investment Representations and Agreements - Life Sciences,
                  Inc.

Gentlemen:

         This letter sets forth my representations, warranties and
acknowledgements to Life Sciences, Inc., a Delaware corporation ("LSI", "you" or
the "Company"), and my related covenants and agreements with you, all in
connection with the offer to purchase from you shares of common stock, $.10 par
value per share, of LSI (the "Common Stock"), at $.4375 per share(1) as the
means of liquidating your indebtedness to me.

         As of the close of business yesterday, April 8, 1999, you were indebted
to me in the aggregate amount of $29,342.13, consisting of $25,000.00 in
principal (the "Principal") and $4,342.13 in interest and other charges
(collectively, the "Other Charges"), all of which is due to me in connection
with one or more loans of money to you as reflected in your books and records.
During my current visit to Florida, you and I have agreed, and upon acceptance
of this letter (this "Investment Representation Letter" or this "Letter") by you
we hereby evidence our agreement, that the Principal shall be paid and
discharged by the sale and issuance by you, in a private offering to me, of
shares of Common Stock at $.4375 per share, and that the Other Charges shall be
forgiven and extinguished upon the date of your acceptance of this Letter
without any further act or deed by either of us. This would result in the sale
and issuance to me of a total of 57,142 whole shares (rounded down in
calculation) of Common Stock (the "Shares") as of the date this Letter. I hereby
subscribe for and agree to purchase the Shares.

         It is in this context that I provide you with this Letter as an
inducement to your sale of the Shares to me, and I intend and realize that the
Company and its agents and representatives will rely on my representations,
warranties, acknowledgements, covenants and agreements set forth in this Letter
in connection with the sale to me of the Shares. I understand that reliance will
also be placed on the accuracy and completeness hereof in complying with the
obligations of applicable securities laws, and that failure to comply with those
obligations may have significant legal consequences.

         (1)      Representations, Etc. Therefore, for good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
preceding three paragraphs are incorporated herein by this reference, and I
represent, warrant, acknowledge, covenant and agree as follows:

                  (a)      My business address is 140 - 53rd Street, Brooklyn,
New York 11232, and my social security number is ###-##-####. Insofar as I am
aware, no commission or other remuneration is payable as a result of my proposed
purchase of the Shares, and no general solicitation or advertisement occurred in
connection therewith.

                  (b)      I am an "accredited investor" within the meaning of
Regulation D under the

- --------
(1) This amount is equal to the last reported high, low and closing prices of
    the Common Stock in the over-the-counter market on March 26, 1999, the
    closest available date for such information prior to the date hereof.

Life Sciences, Inc.                             Investment Representation Letter
April 9, 1999                                                             Page 2

Securities Act of 1933, as amended ("Securities Act"), and the Florida
Securities and Investor Protection Act ("Florida Act") because my current
individual net worth exceeds $1,000,000, and/or I had individual income(2) in
excess of $200,000 in each of the two most recent years and have a reasonable
expectation of reaching the same income level in the current year. I also have
such knowledge and experience in financial and business matters that I am
capable of evaluating the merits and risks of my acquisition of the Shares and
of my investment in LSI. I understand there is no guaranty or assurance that you
ever will be profitable, and that your operating history includes a history of
losses. Accordingly, I am aware of the speculative nature of my proposed
investment and of the significant risks involved, and I represent and warrant
that I can bear the economic risk of such investment. I understand that an
investment in LSI is not suitable for any person who does not so understand such
risks. My investments in and commitments to all non-liquid investments,
including my proposed purchase of the Shares, are reasonable in relation to my
net worth, and I have adequate means of providing for my current needs and
possible contingencies without disposing of my proposed investment in the
Shares. All information I have provided to you concerning my financial position
and knowledge of financial and business matters is correct and complete as of
the date hereof.

                  (c)      I have received and reviewed prior to my
determination to purchase the Shares and prior to the execution and delivery of
this Investment Representation Letter, all of the material information
concerning LSI, the Common Stock, the Shares and other matters that I considered
to be necessary or appropriate in connection with my investment decision.

                  (d)      Among the documents I have had full and fair access
to prior to the execution and delivery of this Letter are all material contracts
to which LSI is a party or by which you are bound or benefitted, your historical
financial statements and related financial information as requested by me, and
the minute book of LSI containing the records of the actions of your Board of
Directors and stockholders.

                  (e)      The Shares are to be acquired by me, in my name only,
for my own account, and no other person has any direct or indirect beneficial
ownership interest or other interest therein. The Shares are to be acquired by
me solely for investment purposes and not with a view to resale or distribution,
and I have no contract, undertaking, agreement or arrangement for any sale,
distribution or other transfer of any interest in any of the Shares, and no
present plans to enter into any such arrangement.

                  (f)      I understand that the offer and sale of the Shares
has not been registered with or reviewed by the Securities and Exchange
Commission under the Securities Act, with or by any agency under the Florida
Act, or with or by any other state securities law administrator on the grounds,
among others, that the issuance and sale thereof is exempt from those
registration requirements on the grounds, among others, of not involving any
public offering and/or that the Shares in the context of this transaction are a
"covered security" as that phrase is defined in Section 18(a) of the Securities
Act and, accordingly, a "federal covered security" as that phrase is defined and
used in the Florida Act. I further understand that your, and your agents' and
representatives', reliance on such exemptions are, in material part, based on my
representations, warranties, acknowledgements, covenants and agreements set
forth herein. I also understand that no federal or state securities law
administrator has reviewed or approved any disclosure or other associated
material concerning the Shares, LSI, the Common Stock or any related matter, and
I acknowledge that my decision to acquire the Shares is of my own volition and
has not been recommended by you or by any federal or state securities law
administrator.

- --------

(2) A measure of a person's income for this purpose is the amount of his
    individual adjusted gross income (as reported on a federal income tax
    return) increased by: (i) any deduction for a portion of long term capital
    gains [Internal Revenue Code ("Code") Section 1202]; (ii) any deduction for
    depletion (Section 611 et. seq. of the Code); (iii) any exclusion for
    interest on tax-exempt municipal obligations (Section 103 of the Code); and
    (iv) any losses of a partnership allocated to the individual limited
    partner (as reported on Schedule E of Form 1040).

April 9, 1999                                                             Page 3

                  (g)      I have been represented by such legal, tax,
accounting, financial and other advisors selected and retained by me as I have
found necessary to consult concerning my proposed purchase of the Shares and my
proposed investment. I have sufficient knowledge and experience in business and
financial matters that I am capable of evaluating all facets of the merits and
risks thereof [or I have used and relied upon in connection with my decision to
purchase the Shares, my own independent purchaser representative (insert
identity of purchaser representative or insert "N/A":            N/A           )
who does have such knowledge and experience and, therefore, the terms "I" and
"me" in this paragraph (g) shall include (as appropriate in the context) such
identified representative], and I investigated all facets of the merits and
risks of such proposed purchase prior to deciding to purchase the Shares. I
acknowledge that I have had full and fair access to all information concerning
LSI, the Shares (and also to other information considered by me to be necessary
or appropriate as a prudent and knowledgeable investor to enable me to make an
informed investment decision concerning the acquisition of the Shares), and that
I was previously informed that all documents, records and books pertaining to
such proposed investment were at all relevant times available for inspection and
review by me. I have determined the information necessary or appropriate for my
review of the merits and risks of my proposed investment, and I shall not seek
to hold you, or any of your agents or representatives, liable for matters
included in or omitted from my investigation based on such determination. I
acknowledge that I have had the opportunity to ask questions of, and have
received satisfactory answers from, you and your officers and directors
concerning LSI, the Shares and related matters. I also acknowledge that I have
had an opportunity to obtain additional information necessary to verify the
accuracy of such information and to evaluate the merits and risks of my proposed
investment. In my determination to acquire the Shares, no person made any
representation or warranty, expressed or implied, to me in any way relating
thereto except as expressly set forth or referenced herein, I have not relied on
any oral representation or warranty, and I did not rely on any offering
literature other than the documents and information made available to me as
provided herein.

                  (h)      I understand that the Shares are not readily
transferable, and that there is only a limited over-the-counter market for the
Common Stock, no assurance is given by anyone that an active and substantial
public market will develop, or if developed that it will be sustained, I may not
be able to readily liquidate my proposed investment in the Shares in any event,
and I must bear the economic risk of an investment therein indefinitely. I also
understand there are substantial restrictions on the sale and transfer of the
Shares I am purchasing, and that subsequent sale or other transfer where
permitted will require registration thereof with applicable federal and state
securities law administrators and/or an opinion of my counsel acceptable to LSI
that any such transfer is exempt from such securities law requirements. I
further understand that legends, including a legend substantially as set forth
in Section (2) below, will be on the certificate issued to represent the Shares.
I agree not to offer, sell, pledge or otherwise transfer any of the Shares or
any interest therein absent compliance with applicable federal and state
securities laws and the referenced legend conditions. I understand that neither
the Company nor any other person has any obligation to register any Common Stock
or to provide me an opinion for the foregoing purposes.

                  (i)      No representation or warranty by me herein contains
any untrue statement of a material fact or omits to state a material fact
necessary to make the statements contained herein not misleading, and the
representations, warranties, acknowledgements, covenants and agreements set
forth herein shall survive the payment, issuance and delivery, of the Shares.

                  (j)      I acknowledge that I understand the meaning and legal
consequences of the representations, warranties, acknowledgements, covenants and
agreements contained herein, and I agree to indemnify and hold LSI and its
agents and representatives harmless from and against any and all loss,

damage, liability or expense, including costs and reasonable attorneys' and
paralegal fees, to which any of them may be put or which they may incur by
reason of, or in connection with, any misrepresentation by me, any breach by me
of any representation or warranty, or any failure by me to fulfill any covenant
or agreement herein. The representations, warranties, acknowledgements,
covenants and agreements set forth in this Letter are intended to benefit each
of the persons described in the preceding sentence.

         (2)      Legends. The Shares shall be subject to any legend condition
necessary to assist in complying with applicable federal and state securities
laws, including such legends as may be appropriate under Regulation D as adopted
by the Securities and Exchange Commission under the Securities Act and the
legend set forth below. In any event, the certificate representing the Shares
shall have endorsed on it a legend reading substantially as follows:

         THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AND MAY NOT BE OFFERED FOR SALE,
         SOLD, HYPOTHECATED OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN
         EFFECTIVE REGISTRATION STATEMENT UNDER THAT ACT OR AN OPINION OF
         COUNSEL SATISFACTORY TO THE ISSUER THAT SUCH REGISTRATION IS NOT
         REQUIRED.

         (3)      Interpretation. Any descriptive headings of or in sections and
paragraphs of this Letter are inserted for convenience only and are not a part
of this Letter. No provision in this Investment Representation Letter shall be
construed against any party as the drafter. As used herein, the singular
includes the plural, the plural includes the singular and words in one gender
include the others; the terms "herein", "hereof", "hereunder" and similar
references refer to the whole of this Investment Representation Letter; and
"include", "including" and similar terms are not words of limitation. Whenever
possible, each provision of this Letter shall be interpreted in such manner as
to be effective and valid under applicable law, but if any provision shall be
prohibited or invalid under applicable law, such provision shall be ineffective
to the extent of such prohibition or invalidity only, without invalidating the
remainder of such provision or of the remaining provisions of this Letter.

         (4)      Miscellaneous. This Investment Representation Letter: (i)
contains the complete statement of all arrangements between LSI and me with
respect to its subject matter, and supersedes all previous agreements, promises,
arrangements and understandings, written or oral, relating to its subject
matter; (ii) cannot be assigned by either party without the other's prior
written consent, and cannot be modified, amended or waived except by an
instrument in writing signed by the parties necessary to the enforcement
thereof; (iii) shall be binding upon and shall inure to the benefit of our
respective successors, permitted assigns, heirs and legal representatives; (iv)
may be executed in any number of counterparts, each of which shall be deemed an
original instrument, but all such counterparts together shall constitute but one
agreement; and (v) shall be governed by, and construed and enforced in
accordance with, the laws of the State of Florida; provided, however, to the
extent Florida law is preempted by federal law, federal law shall apply. LSI and
I each hereby consent to the personal jurisdiction of the state and federal
courts located within the territorial limits of the United States District Court
for the Middle District of Florida, Tampa Division, agree that venue for any
litigation (or mediation or arbitration in connection therewith) related in any
way to this Letter shall only be in Pinellas County, Florida, or, if
appropriate, the United States District Court for the Middle District of
Florida, Tampa Division, and waive any objection to such exclusive jurisdiction
and venue. If either of us retains the services of counsel to enforce any
provision of this Letter, or because of litigation (or mediation or arbitration
in connection therewith) involving this Letter, the prevailing party shall be
entitled to recover, in addition to any other relief or remedy obtained, all
costs, expenses, and attorneys' and paralegal fees paid or incurred by it,
including costs, expenses and such fees at trial and any appeal,

                     STANDARDS FOR REAL ESTATE TRANSACTIONS

(a) EVIDENCE OF TITLE: A title insurance commitment issued by a Florida
licensed title insurer agreeing to issue to Buyer, upon recording of the deed
to Buyer, an owner's policy of title insurance in the amount of the purchase
price, insuring Buyer's title to the Property, subject only to liens,
encumbrances, exceptions or qualification provided in this Contract and those
to be discharged by Seller at or before closing. Seller shall convey marketable
title subject only to liens, encumbrances, exceptions or qualifications
provided in this Contract. Marketable title shall be determined according to
applicable title standards adopted by authority of The Florida Bar and in
accordance with law. Buyer shall have 5 days from the date of receiving
evidence of title to examine it. If title is found defective, Buyer shall
within such 5 days notify Seller in writing specifying any defects. If defects
render title unmarketable, Seller will have 30 days from receipt of written
notice to remove the defects, failing which Buyer shall, within 5 days after
expiration of the 30 day period, deliver written notice to Seller either: (1)
extending the time for a reasonable period not to exceed 60 additional days
within which Seller shall use diligent effort to remove the defects; or (2)
requesting a refund of the Deposit, which shall immediately be returned to
Buyer. If Buyer fails to so notify Seller, Buyer shall be deemed to have
accepted the title as it then is. Seller shall, if title is found unmarketable,
use diligent effort to correct any defects within the time provided therefor.
If Seller is unable to timely correct the defects, Buyer shall either waive the
defects, or receive a refund of the Deposit, thereby releasing Buyer and Seller
form all further obligations under this Contract. If evidence of title is
delivered to Buyer less than 5 days prior to closing, Buyer may extend the
closing date so that Buyer shall have up to 5 days from the date of receipt of
evidence of title to examine the same in accordance with this paragraph (a).

(b) SURVEY: Seller, within time allowed to deliver evidence of title and to
examine same, shall have the Property surveyed and certified by a registered
Florida surveyor. If the survey discloses encroachments on the Property, other
than from real property currently owned or occupied by Buyer, or that any
improvements located thereon encroach on setback lines, easements, lands of
others or violate any restrictions, contract covenants or applicable
governmental regulation, the same shall constitute a title defect. Seller shall
also cause such surveyor to prepare the legal descriptions and related drawing
of the Easement Area for the Driveway Easement referenced in Section 5 of this
Contract. The cost of the survey of the Property and of the Easement Area shall
be paid 1/2 by Buyer and 1/2 by Seller as part of the closing of the
Transaction.

(c) LIENS: Seller shall furnish to Buyer at time of closing an affidavit
attesting to the absence, unless otherwise provided for herein, of any
financing statement, claims of lien or potential lienors arising or resulting
from work or materials ordered at the instance or behest of Seller and further
attesting that there has not been at the instance or behest of Seller any
improvements or repairs to the Property for 90 days immediately preceding the
date of closing. If the Property has been improved or repaired within that time
at the instance or behest of Seller, Seller shall deliver releases or waivers
of construction liens executed by all general contractors, subcontractors,
suppliers, and materialmen in addition to Seller's lien affidavit setting forth
the names of all such persons, further affirming that all charges for such
improvements or repairs ordered at the instance or behest of Seller which could
serve as a basis for a construction lien or a claim for damages have been paid
or will be paid at the closing of this Contract. The foregoing requirements of
Seller shall not apply to the extent any such person, work or materials were
retained or ordered by, or are the obligation of, Buyer.

(d) TIME: Time is of the essence of this Contract. In computing time periods of
less than 6 days, Saturdays, Sundays and state or national legal holidays shall
be excluded. Any time periods provided for herein which shall end on a
Saturday, Sunday or a legal holiday shall extend to 5:00 p.m. of the next
business day.

(e) CLOSING DOCUMENTS: Seller shall furnish the deed, Seller's lien affidavit,
Seller's possession affidavit and corrective instruments attributable to acts
or omissions of Seller. Buyer shall furnish those items reasonably requested by
Escrow Agent.

(f) EXPENSES: Recording of corrective instruments shall be paid by Seller.
Documentary stamps on the deed and recording the deed shall be paid 1/2 by
Buyer and 1/2 by Seller. Charges for the following related title services,
namely title or abstract charge, title examination, and settlement and closing
fee, shall also be paid 1/2 by Buyer and 1/2 by Seller.

(g) PRORATIONS; CREDITS: Taxes, assessments and other expenses of the Property
shall be prorated through the day before closing. Cash at closing shall be
increased or decreased as may be required by prorations to be made through the
day prior to closing, or occupancy, if occupancy occurs before closing. Taxes
shall be prorated based on the current year's tax with due allowance made for
maximum allowable discount, homestead and other exemptions. If closing occurs
at a date when the current year's millage is not fixed and current year's
assessment is available, taxes will be prorated based on such assessment and
prior year's millage. If current year's assessment is not available, then taxes
will be prorated on prior year's tax. A tax proration based on an estimate
shall, at request of either party, be readjusted upon receipt of tax bill on
condition that a statement to that effect is signed at closing.

(h) SPECIAL ASSESSMENT LIENS: Certified, confirmed and ratified special
assessment liens as of date of closing (not as of Effective Date) are to be
paid by Seller. Pending liens as of date of closing shall be assumed by Buyer.
If the improvement has been substantially completed as of Effective Date, any
pending lien shall be considered certified, confirmed or ratified and Seller
shall, at closing, be charged an amount equal to the last estimate or
assessment for the improvement by the public body.

(i) RISK OF LOSS: If the Property is damaged by any casualty before closing and
cost of restoration does not exceed $2,500.00, cost of restoration shall be an
obligation of Seller and closing shall proceed pursuant to the terms of this
Contract with restoration costs escrowed at closing. If the cost of restoration
exceeds such amount and Seller does not elect to pay the additional cost, Buyer
shall have the option of either taking the Property as is, together with either
such amount or any insurance proceeds payable by virtue of such loss or damage,
or of canceling this Contract and receiving return of the Deposit.

(j) ESCROW: Escrow Agent is authorized and agrees by acceptance of the Deposit
to deposit them promptly, hold same in escrow and, subject to clearance,
disburse them in accordance with terms and conditions of this Contract. Failure
of funds to clear shall not excuse Buyer's performance. If in doubt as to
Escrow Agent's duties or liabilities under this Contract, Escrow Agent may, at
Escrow Agent's option, continue to hold the subject matter of the escrow until
the parties hereto agree to its disbursement or until a judgment of a court of
competent jurisdiction shall determine the rights of the parties, or Escrow
Agent may deposit the same with the clerk of the circuit court having
jurisdiction of the dispute. Upon notifying all parties concerned of such
action, all liability on the part of Escrow Agent shall terminate, except to
the extent of accounting for any items previously delivered out of escrow. Any
suit between Buyer and Seller wherein Escrow Agent is made a party because of
acting as Escrow Agent hereunder, or in any suit wherein Escrow Agent
interpleads the subject matter of the escrow, Escrow Agent shall recover
reasonable attorneys' fees and costs incurred, with these amounts to be paid
out of the escrowed funds or equivalent and charged and awarded as court costs
in favor of the prevailing party. Escrow Agent shall not be liable to any party
or person for misdelivery to Buyer or Seller of items subject to the escrow,
unless such misdelivery is due to willful breach of the provisions of this
Contract or gross negligence of Escrow Agent.

(k) ATTORNEYS' FEES; COSTS: In any litigation, including breach, enforcement or
interpretation, arising out of this Contract, the prevailing party in such
litigation shall be entitled to recover from the non-prevailing party
reasonable attorneys' fees and costs.

(l) FAILURE OF PERFORMANCE: If Buyer fails to perform this Contract within the
time specified, the Deposit paid by Buyer may be recovered and retained by and
for the account of Seller as agreed upon liquidated damages, consideration for
the execution of this Contract and in full settlement of any claims; whereupon,
Buyer and Seller shall be relieved of all further obligations under this
Contract; or Seller, at Seller's option, may proceed in equity to enforce
Seller's rights under this Contract. If, for any reason other than failure of
Seller to make Seller's title marketable after diligent effort, Seller fails,
neglects or refuses to perform this Contract, Buyer may seek specific
performance or elect to receive the return of the Deposit without thereby
waiving any action for damages resulting from Seller's breach.

(m) CONTRACT NOT RECORDABLE; PERSONS BOUND: Neither this Contract nor any
notice of it shall be recorded in any public records. This Contract shall bind
and inure to the benefit of the parties and their successors in interest.
Whenever the context permits, the singular shall include the plural, and one
gender shall include all.

(n) HEADINGS; OTHER AGREEMENTS: The headings of the section and paragraphs of
this Contract are inserted for convenience only and are not a part of this
Contract. This Contract shall not be construed against any party as the
drafter. No prior or present agreement or warranty shall be binding on Buyer or
Seller, unless included in this Contract. No modification to or change in this
Contract shall be valid or binding upon the parties unless in writing and
executed by the party or parties intended to be bound by it.

                     STANDARDS FOR REAL ESTATE TRANSACTIONS

(a) EVIDENCE OF TITLE: A title insurance commitment issued by a Florida
licensed title insurer agreeing to issue to Buyer, upon recording of the deed
to Buyer, an owner's policy of title insurance in the amount of the purchase
price, insuring Buyer's title to the Property, subject only to liens,
encumbrances, exceptions or qualifications provided in this Contract and those
to be discharged by Seller at or before closing. Seller shall convey marketable
title subject only to liens, encumbrances, exceptions or qualifications
provided in this Contract. Marketable title shall be determined according to
applicable title standards adopted by authority of The Florida Bar and in
accordance with law. Buyer shall have 2 days from the date of receiving
evidence of title to examine it. If title is found defective, Buyer shall
within such 2 days notify Seller in writing specifying any defects. If defects
render title unmarketable, Seller will have 30 days from receipt of written
notice to remove the defects, failing which Buyer shall, within 5 days after
expiration of the 30 day period, deliver written notice to Seller either: (1)
extending the time for a reasonable period not to exceed 60 additional days
within which Seller shall use diligent effort to remove the defects; or (2)
Buyer shall pay title and escrow charges incurred and the Transaction shall be
terminated. If Buyer fails to so notify Seller, Buyer shall be deemed to have
accepted the title as it then is. Seller shall, if title is found unmarketable,
use diligent effort to correct any defects within the time provided therefor.
If Seller is unable to timely correct the defects, Buyer shall either waive the
defects, or shall pay title and escrow charges incurred, thereby releasing
Buyer and Seller from all further obligations under this Contract. If evidence
of title is delivered to Buyer less than 2 days prior to closing, Buyer may
extend the closing date so that Buyer shall have up to 2 days from the date of
receipt of evidence of title to examine the same in accordance with this
paragraph (a).

(b) SURVEY: Seller, at Buyer's expense, within time allowed to deliver evidence
of title and to examine same, shall have the Property surveyed and certified by
a registered Florida surveyor. If the survey discloses encroachments on the
Property, or that any improvements located thereon encroach on setback lines,
easements, lands of others or violate any restrictions, contract covenants or
applicable governmental regulation, the same shall constitute a title defect.

(c) LIENS: Seller shall furnish to Buyer at time of closing an affidavit
attesting to the absence, unless otherwise provided for herein, of any
financing statement, claims of lien or potential lienors arising or resulting
from work or materials ordered at the instance or behest of Seller and further
attesting that there has not been at the instance or behest of Seller any
improvements or repairs to the Property for 90 days immediately preceding the
date of closing. If the Property has been improved or repaired within that time
at the instance or behest of Seller, Seller shall deliver releases or waivers
of construction liens executed by all general contractors, subcontractors,
suppliers, and materialmen in addition to Seller's lien affidavit setting forth
the names of all such persons, further affirming that all charges for such
improvements or repairs ordered at the instance or behest of Seller which could
serve as a basis for a construction lien or a claim for damages have been paid
or will be paid at the closing of this Contract. The foregoing requirements of
Seller shall not apply to the extent any such person, work or materials were
retained or ordered by, or are the obligation of, Buyer.

(d) TIME: Time is of the essence of this Contract. In computing time periods of
less than 6 days, Saturdays, Sundays and state or national legal holidays shall
be excluded. Any time periods provided for herein which shall end on a
Saturday, Sunday or a legal holiday shall extend to 5:00 p.m. of the next
business day.

(e) CLOSING DOCUMENTS: Seller shall furnish the deed, Seller's
lien affidavit, Seller's possession affidavit and corrective instruments
attributable to acts or omissions of Seller. Buyer shall furnish the
Satisfaction and those other items reasonably requested by Escrow Agent.

(f) EXPENSES: Recording of corrective instruments other than the Satisfaction
shall be paid by Seller. Documentary stamps on the deed and recording the deed
and the Satisfaction shall be paid by Buyer. Charges for the following related
title services, namely title or abstract charge, title examination, and
settlement and closing fee, shall be paid by Buyer as the party responsible for
paying for the title evidence in accordance with Section 4 of this Contract.

(g) PRORATIONS; CREDITS: Taxes, assessments and other expenses of the Property
shall be prorated through the day before closing. Cash at closing shall be
increased or decreased as may be required by prorations to be made through the
day prior to closing, or occupancy, if occupancy occurs before closing. Taxes
shall be prorated based on the current year's tax with due allowance made for
maximum allowable discount, homestead and other exemptions. If closing occurs
at a date when the current year's millage is not fixed and current year's
assessment is available, taxes will be prorated based on such assessment and
prior year's millage. If current year's assessment is not available, then taxes
will be prorated on prior year's tax. A tax proration based on an estimate
shall, at request of either party, be readjusted upon receipt of tax bill on
condition that a statement to that effect is signed at closing.

<PAGE>   3

(h) SPECIAL ASSESSMENT LIENS: Certified, confirmed and ratified special
assessment liens as of date of closing (not as of Effective Date) are to be
paid by Seller. Pending liens as of date of closing shall be assumed by Buyer.
If the improvement has been substantially completed as of Effective Date, any
pending lien shall be considered certified, confirmed or ratified and Seller
shall, at closing, be charged an amount equal to the last estimate or
assessment for the improvement by the public body.

(i) RISK OF LOSS: If the Property is damaged by any casualty before closing and
cost of restoration does not exceed $2,500.00, cost of restoration shall be an
obligation of Seller outside of the Transaction and closing shall proceed
pursuant to the terms of this Contract. If the cost of restoration exceeds such
amount and Seller does not elect to pay the additional cost, Buyer shall have
the option of either taking the Property as is, together with either such
amount or any insurance proceeds payable by virtue of such loss or damage, or
of canceling this Contract and paying title and escrow charges incurred.

(j) ESCROW: Escrow Agent is authorized and agrees by execution hereof to hold
the documents and funds deposited in escrow under this Contract and, subject to
clearance as to funds, to disburse them in accordance with terms and conditions
of this Contract. If in doubt as to Escrow Agent's duties or liabilities under
this Contract, Escrow Agent may, at Escrow Agent's option, continue to hold the
subject matter of the escrow until the parties hereto agree to its disbursement
or until a judgment of a court of competent jurisdiction shall determine the
rights of the parties, or Escrow Agent may deposit the same with the clerk of
the circuit court having jurisdiction of the dispute. Upon notifying all
parties concerned of such action, all liability on the part of Escrow Agent
shall terminate, except to the extent of accounting for any items previously
delivered out of escrow. Any suit between Buyer and Seller wherein Escrow Agent
is made a party because of acting as Escrow Agent hereunder, or in any suit
wherein Escrow Agent interpleads the subject matter of the escrow, Escrow Agent
shall recover reasonable attorneys' fees and costs incurred, with these amounts
to be paid out of the escrowed funds or equivalent and charged and awarded as
court costs in favor of the prevailing party. Escrow Agent shall not be liable
to any party or person for misdelivery to Buyer or Seller of items subject to
the escrow, unless such misdelivery is due to willful breach of the provisions
of this Contract or gross negligence of Escrow Agent.

(k) ATTORNEYS' FEES; COSTS: In any litigation, including for breach,
enforcement or interpretation, arising out of this Contract, the prevailing
party in such litigation shall be entitled to recover from the non-prevailing
party reasonable attorneys' fees and costs.

(l) FAILURE OF PERFORMANCE: If Buyer fails to perform this Contract within the
time specified, Seller, at Seller's option, may proceed in equity to enforce
Seller's rights under this Contract. If, for any reason other than failure of
Seller to make Seller's title marketable after diligent effort, Seller fails,
neglects or refuses to perform this Contract, Buyer may seek specific
performance or elect to pay title and escrow charges incurred without thereby
waiving any action for damages resulting from Seller's breach.

(m) CONTRACT NOT RECORDABLE; PERSONS BOUND: Neither this Contract nor any
notice of it shall be recorded in any public records. This Contract shall bind
and inure to the benefit of the parties and their successors in interest.
Whenever the context permits, the singular shall include the plural, and one
gender shall include all.

(n) HEADINGS; OTHER AGREEMENTS: The headings of the section and paragraphs of
this Contract are inserted for convenience only and are not a part of this
Contract. This Contract shall not be construed against any party as the
drafter. No prior or present agreement or warranty shall be binding on Buyer or
Seller, unless included or referred to in this Contract. No modification to or
change in this Contract shall be valid or binding upon the parties unless in
writing and executed by the party or parties intended to be bound by it.

                           DRIVEWAY EASEMENT AGREEMENT


     This DRIVEWAY EASEMENT AGREEMENT ("Agreement") is made and entered into on
May 27, 1999 by and between LIFE SCIENCES, INC., a Delaware corporation ("LSI"),
and CAVAFORM, INC., a Florida corporation ("Cavaform").

RECITALS:

     (a) LSI is the owner of the real property situate, lying and being in
Pinellas County, Florida and described on the attached Exhibit A, which is
incorporated herein by this reference ("Exhibit A), as PARCEL ONE. This property
and each part thereof is sometimes referred in this Agreement as the "LSI
Property".

     (b) On or about the date hereof, Cavaform became the owner, through
acquisition from LSI, of the real property situate, lying and being in Pinellas
County, Florida and described on Exhibit A as PARCEL TWO. This property and each
part thereof is sometimes referred to in this Agreement as the "Cavaform
Property".

     (c) By this Agreement, the parties desire to establish and to regulate a
driveway easement from 72nd Street North, St. Petersburg, Florida for ingress
and egress to and from the LSI Property and the Cavaform Property (sometimes
collectively referred to herein as the "Benefited Property"), such driveway
easement (the "Driveway Easement") to be over the southerly portion of the LSI
Property and the northerly portion of the Cavaform Property. Such southerly and
northerly portions of property are more particularly described as the real
property situate, lying and being in Pinellas County, Florida and described on
Exhibit A as PARCEL THREE (the "LSI Easement Parcel") and PARCEL FOUR (the
"Cavaform Easement Parcel"). The LSI Easement Parcel and the Cavaform Easement
Parcel are sometimes collectively referred to in this Agreement as the "Easement
Area". The Easement Area is more particularly described as the real property
situate, lying and being in Pinellas County, Florida and described on Exhibit A
as PARCEL FIVE.

     NOW, THEREFORE, in consideration of the foregoing and the covenants
contained herein, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged by LSI and Cavaform, the parties
agree as follows:

1. RECITALS. The foregoing recitals are true and correct, and are incorporated
herein by this reference.

2. GRANTS OF EASEMENTS. On the terms and conditions herein contained, LSI hereby
grants to Cavaform, and to the successors in title to the Cavaform Property, for
the use and benefit of the Cavaform Property, a perpetual, non-exclusive
easement for ingress and egress to the Cavaform Property, on, over and across
the LSI Easement Parcel. On the terms and conditions herein contained, Cavaform
hereby grants to LSI, and to the successors in title to the LSI Property, for
the use and benefit of the LSI Property, a perpetual, non-exclusive easement for
ingress and egress to the LSI Property, on, over and across the Cavaform
Easement Parcel.

3. USE. Without limiting the other provisions of this Agreement, the Driveway
Easement may be used for the intended purpose of providing ingress and egress to
and from the Benefited Property by the respective employees, agents, tenants,
subtenants, licensees, mortgagees in possession, customers and business invitees
of the owners of the Benefited Property. Neither of the parties shall do
anything that will impair the use of the Driveway Easement for its intended
purpose; provided, however, that limited impairment of use resulting from
construction, repair and maintenance of improvements to the Driveway Easement is
not a breach of this provision. Parking or standing of vehicles in the Driveway
Easement is not permitted, except as requisite in and about the construction,
repair and maintenance of improvements to the Driveway Easement.

4. COVENANTS RUNNING WITH THE LAND. The terms, covenants and conditions set
forth in this Agreement shall run with the real property described herein (i.e.,
the Benefited Property and the Easement Area) and shall benefit and bind the
parties, and any successor owner of all or any portion of the real property
described in this Agreement. Subsequent owners of all or any portion of the
Benefited Property shall have the full benefit and right of enjoyment of the
easements and other rights herein granted. The rights, benefits and obligations
of this Agreement shall be transferred and conveyed upon transfer or conveyance
of any portion of real property benefited or burdened by the easements herein
granted without the need of any reference to this Agreement.




<PAGE>   2

5. NO PUBLIC DEDICATION. Nothing contained in this Agreement shall be deemed to
be a gift or dedication of any portion of any real property described herein to
the general public or for any public use or purpose.

6. CONSTRUCTION, REPAIR AND MAINTENANCE. At its sole cost and expense, Cavaform
shall construct, or shall cause to be constructed, improvements, including
asphalt paving and concrete curbing, within the Easement Area suitable to the
use thereof as the Driveway Easement, and thereafter shall maintain the same, or
cause it to be maintained, in good repair and in a safe, well-lighted, clean and
orderly condition, and shall provide suitable insurance with respect to the
same. Notwithstanding the foregoing, from and after such time as the owner of
the LSI Easement Parcel makes more than an incidental use of the Driveway
Easement, such owner shall be responsible for reimbursing the party performing
the maintenance on, and providing the insurance with respect to, the Driveway
Easement for one-half of the reasonable cost of such maintenance and insurance
applicable to the Driveway Easement for periods of time after the commencement
of more than such an incidental use. Each party shall be solely responsible for
the property taxes and assessments on that portion of the Easement Area owned by
the party.

7. DAMAGE. If any owner of any of the Benefited Property, or such owner's
employees, agents, tenants, subtenants, licensees, mortgagees in possession,
customers or business invitees, cause any damage (such owner is referred to as
the "Applicable Owner") to the Driveway Easement, the Applicable Owner shall
immediately begin the repair of such damage at its sole cost and expense and
diligently complete such repairs as soon as reasonably possible, but in no event
later than 30 days after such property is damaged.

8. FAILURE TO MAINTAIN AND REPAIR. If any person responsible for construction,
repair or maintenance under the provisions of this Agreement fails to perform
its obligations hereunder (the "Defaulting Owner"), then after notice to the
Defaulting Owner by another owner of property affected by this Agreement (the
"Non-Defaulting Owner"), and provided that the Defaulting Owner does not
commence its construction, repair or maintenance obligations within five days
after receiving the notice and diligently complete the performance of such
maintenance and repair obligations as soon as reasonably possible, but in no
event more than 30 days after the delivery of such notice, the Non-Defaulting
Owner shall have the right, but not the obligation, to perform any of the
obligations of the Defaulting Owner. In the event of an emergency, the
Non-Defaulting Owner may immediately perform the obligations of the Defaulting
Owner. All reasonable costs and expenses incurred by the Non-Defaulting Owner in
connection with the Defaulting Owner's failure to perform, together with
interest at the highest lawful rate per annum from the date of the expenditure
of such funds (the "Remediation Costs") shall be due from the Defaulting Owner
to the Non-Defaulting Owner upon receipt of a bill therefor. The Remediation
Costs shall be the obligation of the Defaulting Owner, and the Non-Defaulting
Owner shall have a lien against the property owned by the Defaulting Owner and
subject to this Agreement ("Defaulting Owner's Property") to secure the
Remediation Costs. The priority of such lien shall be the date a claim of lien,
stating the amount of Remediation Costs and specifying that the lien is against
the Defaulting Owner's Property, is mailed to the Defaulting Owner and recorded
in the public records of Pinellas County, Florida. Such lien may be foreclosed
in the same manner as a real estate mortgage.

9. INTERPRETATION. In the event any provision of this Agreement is determined to
be invalid, illegal, void or unenforceable, in whole or in part, such
determination shall not be construed to invalidate the remaining provisions of
this Agreement which shall remain in full force and effect. Descriptive headings
of or in sections and any exhibits are inserted for convenience only and are not
a part of this Agreement. Any time period provided for herein which shall end
on, and any date provided for herein which is on, a Saturday, Sunday or legal
holiday in the United States shall extend to 5:00 p.m. of the next business day.
Unless otherwise qualified, references in this Agreement to "Section" or
"section" are to provisions of this Agreement and a reference thereto includes
any subparts, and the use of the terms "party" or "parties" are references to
Cavaform and/or LSI, and their respective successors as contemplated by Sections
2 and 4, as required or permitted by the context. As used herein, the singular
includes the plural, the plural includes the singular and words in one gender
include the others; the terms "herein", "hereof", "hereunder" and similar
references refer to the whole of this Agreement; and "include", "including" and
similar terms are not words of limitation. This Agreement shall not be construed
against any party as the drafter, and may not be waived, amended or modified in
any respect except by further agreement in writing duly executed by all parties
that own the real property that is affected by such waiver, amendment or
modification.

10. GENERAL. This Agreement: (i) shall become effective on the date it is first
recorded in the public records of Pinellas County, Florida; (ii) contains the
entire statement of all arrangements, representations, warranties, promises,
covenants, understandings and agreements, written or oral, between LSI and
Cavaform with respect to its subject matter, and supersedes all previous
arrangements, representations, warranties, promises, covenants, understandings
and agreements, written or oral, relating to its subject matter; and (iii) shall
be governed by, and construed and enforced in accordance with, the internal laws
of the State of Florida without reference to its laws relating to the conflict
of laws; provided, however, to the extent Florida law is preempted by federal
law, federal law shall apply. With respect to the Driveway Easement, each of the
parties shall comply with all applicable laws, rules, regulations and
requirements of public authorities, and shall indemnify, defend and hold
harmless each owner of real property underlying the Easement Area against all
claims, demands, loss, damage, liabilities,




                                                                          PAGE 2
<PAGE>   3

suits, actions and judgments (including costs and reasonable attorneys' and
paralegals' fees) arising or resulting out of, or related to, the other party's
use (including use by such party's employees, agents, tenants, subtenants,
licensees, mortgagees in possession, customers or business invitees) of the
portion of the Driveway Easement that is upon such owner's real property. In the
event of litigation involving this Agreement, each party irrevocably consents to
the exclusive personal jurisdiction over that party of the courts (both federal
and state) located within the territorial limits of the United States District
Court for the Middle District of Florida, Tampa Division, in the State of
Florida and to venue therein for all purposes, and the prevailing party shall be
entitled to recover as part of the judgment its costs of suit, including
reasonable attorneys' and paralegals' fees, at trial and on appeal. The defense
to an action for the specific enforcement of this Agreement that the remedy of
damages alone may be adequate is waived by each of the parties.

11. NOTICE. Any notice given to any party under this Agreement shall be valid
only if in writing and shall be deemed to be duly given only if delivered
personally or sent by courier service, by overnight delivery service, or by
registered or certified mail, postage prepaid, addressed to the respective
addresses of the parties set forth under their signatures below. Either party
may by notice to the other change its address for notice. Notice shall be
effectively given upon the earlier of actual receipt or three days after
forwarding. In the event notice is mailed as provided in this section and is
returned to the sender for any reason, that notice shall be deemed to have been
received by the party to whom it was addressed on the date the notice was
initially placed in the U. S. Postal Service by the sender.

     IN WITNESS WHEREOF, LSI and Cavaform have caused this Driveway Easement
Agreement to be executed, acknowledged and delivered in their respective names
by duly authorized officers on the date first written above.

         During his current visit to Florida, Simon Srybnik has, for himself,
individually, and as an authorized officer of each of the entities named in the
foregoing table (the "Entities") reached agreement with you, and upon
acceptance by you of this letter (this "Investment Representation Letter" or
this "Letter") it shall evidence the agreement between you and us, that the
individual amounts of Principal shall be paid and discharged by the sale and
issuance by you, in a private offering to us, of shares of Common Stock at

(1)  This amount is the approximate mean between the last available reported
     bid and ask prices of the Common Stock in the over-the-counter market

(2)  Interest included in the table is calculated through May 31, 1999, the
     five additional days being immaterial under the circumstances. It is
     understood that late payment charges were never booked by the Company;

         It is in this context that we provide you with this Letter as an
inducement to your sale of the Shares to us, and each of us intend and realize
that the Company and its agents and representatives will rely on our individual
representations, warranties, acknowledgements, covenants and agreements set
forth in this Letter in connection with the sale to us of the Shares. We each
understand that reliance will also be placed on the accuracy and completeness
hereof in complying with the obligations of applicable securities laws, and
that failure to comply with those obligations may have significant legal
consequences.

         (1) Representations, Etc. Therefore, for good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
each of the preceding portions of this Letter is incorporated herein by this
reference, and we each for ourselves individually (severally, and not jointly
and severally) represent, warrant, acknowledge, covenant and agree as follows:

             (a) Except as otherwise set forth in the immediately preceding
table, the business address for each of us is 140 - 53rd Street, Brooklyn, New
York 11232. Our respective employer identification numbers or social security
number are as set forth in that same table. Insofar as we are individually
aware, no commission or other remuneration is payable as a result of our
respective proposed purchases of the Shares, and no general solicitation or
advertisement occurred in connection therewith.

             (b) We are each an "accredited investor" within the meaning of
Regulation D under the Securities Act of 1933, as amended ("Securities Act"),
and the Florida Securities and Investor Protection Act ("Florida Act") because,
(i) in the case of Simon Srybnik, his current individual net worth exceeds
$1,000,000 and/or he had individual income(3) in excess of $200,000 in each of
the two most recent years and has a reasonable expectation of reaching the same
income level in the current year, and (ii) in the case of each of the Entities,
each of the three stockholders of each of the Entities (i.e., Simon Srybnik,
Louis D. Srybnik and Julius B. Srybnik), each of whom owns one-third of the
outstanding stock of each of the Entities, is an accredited investor by virtue
of having a current individual net worth in excess of $1,000,000

- ---------------

3  A measure of a person's income for this purpose is the amount of his
   individual adjusted gross income (as reported on a federal income tax
   return) increased by: (i) any deduction for a portion of long term capital
   gains [Internal Revenue Code ("Code") Section 1202]; (ii) any deduction for
   depletion (Section 611 et. seq. of the Code); (iii) any exclusion for
   interest on tax-exempt municipal obligations (Section 103 of the Code); and
   (iv) any losses of a partnership allocated to the individual limited partner
   (as reported on Schedule E of Form 1040).

and/or because he had individual income(4) in excess of $200,000 in each of the
two most recent years and has a reasonable expectation of reaching the same
income level in the current year. We each also have such knowledge and
experience in financial and business matters that we are capable of evaluating
the merits and risks of our respective acquisitions of the Shares and of our
investments in LSI. We understand there is no guaranty or assurance that you
ever will be profitable, and that your operating history includes a history of
losses. Accordingly, we are aware of the speculative nature of our proposed
investments and of the significant risks involved, and we represent and warrant
that we can individually bear the economic risk of such investments. We
understand that an investment in LSI is not suitable for any person who does
not so understand such risks. Our respective investments in and commitments to
all non-liquid investments, including our individual proposed purchases of the
Shares, are reasonable in relation to our respective net worths, and we each
have adequate means of providing for our respective current needs and possible
contingencies without disposing of our respective proposed investments in the
Shares. All information we have provided to you concerning our respective
financial positions and knowledge of financial and business matters is correct
and complete as of the date hereof.

             (c) We have received and reviewed prior to our individual
determinations to purchase the Shares and prior to the execution and delivery
of this Investment Representation Letter, all of the material information
concerning LSI, the Common Stock, the Shares and other matters that we
considered to be necessary or appropriate in connection with our respective
investment decisions.

             (d) Among the documents we have had full and fair access to prior
to the execution and delivery of this Letter are all material contracts to
which LSI is a party or by which you are bound or benefitted, your historical
financial statements and related financial information as requested by one or
more of us, and the minute book of LSI containing the records of the actions of
your Board of Directors and stockholders.

             (e) The Shares are to be acquired by us individually, in our own
respective names only, for our own respective accounts, and no other person has
any direct or indirect beneficial ownership interest or other interest therein,
other than the stockholders of the Entities in their capacities as such. The
Shares are to be individually acquired by us solely for investment purposes and
not with a view to resale or distribution, and none of us has any contract,
undertaking, agreement or arrangement for any sale, distribution or other
transfer of any interest in any of the Shares, and no present plans to enter
into any such arrangement.

             (f) We each understand that the offer and sale of the Shares has
not been registered with or reviewed by the Securities and Exchange Commission
under the Securities Act, with or by any agency under the Florida Act, or with
or by any other state securities law administrator on the grounds, among
others, that the issuance and sale thereof is exempt from those registration
requirements on the grounds, among others, of not involving any public offering
and/or that the Shares in the context of these transactions are a "covered
security" as that phrase is defined in Section 18(a) of the Securities Act and,
accordingly, a "federal covered security" as that phrase is defined and used in
the Florida Act. We each further understand that your, and your agents' and
representatives', reliance on such exemptions are, in material part, based on
our representations, warranties, acknowledgements, covenants and agreements set
forth herein. We also each understand that no federal or state securities law
administrator has reviewed or approved any disclosure or other associated
material concerning the Shares, LSI, the Common Stock or any related matter,
and we each acknowledge that our respective decisions to acquire the Shares is
of our own

volition and has not been recommended by you or by any federal or state
securities law administrator.

             (g) We have been represented by such legal, tax, accounting,
financial and other advisors selected and retained by us as we have
individually found necessary to consult concerning our respective proposed
purchases of the Shares and our respective proposed investments. We have
sufficient knowledge and experience in business and financial matters that we
are individually capable of evaluating all facets of the merits and risks
thereof [or one or more of us have used and relied upon in connection with our
respective decisions to purchase the Shares, our own independent purchaser
representative [insert identity of purchaser representative(s) or insert "N/A":
                                     N/A ]
                      -----------------------------------

who does have such knowledge and experience and, therefore, the terms - "we"
and "us" in this paragraph (g) shall include (as appropriate in the context)
such identified representative(s) for those of us, if any, who have used such a
representative], and we each investigated all facets of the merits and risks of
such proposed purchases prior to deciding to purchase the Shares. We each
acknowledge that we have had full and fair access to all information concerning
LSI, the Shares (and also to other information considered by us individually to
be necessary or appropriate as a prudent and knowledgeable investor to enable
us individually to make an informed investment decision concerning the
acquisition of the Shares), and that we were previously informed that all
documents, records and books pertaining to such proposed investments were at
all relevant times available for inspection and review by us. We have each
determined the information necessary or appropriate for our respective reviews
of the merits and risks of our proposed investments, and we shall not seek to
hold you, or any of your agents or representatives, liable for matters included
in or omitted from our respective investigations based on such determinations.
We acknowledge that we have had the opportunity to ask questions of, and have
received satisfactory answers from, you and your officers and directors
concerning LSI, the Shares and related matters. We also acknowledge that we
have each had an opportunity to obtain additional information necessary to
verify the accuracy of such information and to evaluate the merits and risks of
our proposed investments. In our respective determinations to acquire the
Shares, no person made any representation or warranty, expressed or implied, to
any of us in any way relating thereto except as expressly set forth or
referenced herein, we have not relied on any oral representation or warranty,
and we did not rely on any offering literature other than the documents and
information made available to us individually as provided herein.

             (h) We each understand that the Shares are not readily
transferable, and that there is only a limited over-the-counter market for the
Common Stock, no assurance is given by anyone that an active and substantial
public market will develop, or if developed that it will be sustained, we may
not be able to readily liquidate our proposed investments in the Shares in any
event, and we must bear the economic risk of an investment therein
indefinitely. We also understand there are substantial restrictions on the sale
and transfer of the Shares we are purchasing, and that subsequent sale or other
transfer where permitted will require registration thereof with applicable
federal and state securities law administrators and/or an opinion of our
counsel acceptable to LSI that any such transfer is exempt from such securities
law requirements. We each further understand that legends, including a legend
substantially as set forth in Section (2) below, will be on the certificates
issued to each of us to represent our individual portions of the Shares. We
each agree not to offer, sell, pledge or otherwise transfer any of the Shares
or any interest therein absent compliance with applicable federal and state
securities laws and the referenced legend conditions. We each understand that
neither the Company nor any other person has any obligation to register any
Common Stock or to provide any of us an opinion for the foregoing purposes.

             (i) No representation or warranty by any of us herein contains any
untrue statement of a material fact or omits to state a material fact necessary
to make the statements contained herein not misleading, and the
representations, warranties, acknowledgements, covenants and agreements set
forth herein shall survive the payment, issuance and delivery, of the Shares.

             (j) We each acknowledge that we understand the meaning and legal
consequences of our individual representations, warranties, acknowledgements,

hold LSI and its agents and representatives harmless from and against any and
all loss, damage, liability or expense, including costs and reasonable

         EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER
         THAT ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER
         THAT SUCH REGISTRATION IS NOT REQUIRED.

Dear Tony and Larry:


Over the past year we have discussed a variety of proposals that would enable us
jointly to bring to market NASBA based products for detection of food home
pathogens. That the concept has retained its viability despite the many
distractions that we at Life Sciences have experienced during the interim
encourages me that our objectives are valid and with a modicum of good fortune
some measure of success in the food testing marketplace should be readily
achievable.

In our most recent discussions, I advised you that LSI had completed its
negotiations to license the electrochemical detection technology that has been
patented by Cornell University. Further, we have continued our discussions with
Princeton Separations to develop a NASBA compatible electrochemiluminescent
technology that would provide the basis for an absorbance based, qualitative
assessment of the amplicons yielded in a successful NASBA reaction. These steps,
together with LSl's continuing effort to develop a solid state cassette to carry
out NASBA reactions using immobilized enzymes and primers, are expected to fuel
our opportunity for successful early on financing to support the development and
marketing of food testing products. The factors set out above are significant
elements in the follow on proposals for joint activities between our
organizations.

In our most recent series of discussions on various aspects of proposed
collaborations, we agreed in principle that LSI and 1144668 Ontario Ltd.
(Numberco) would, subject to definitive documentation, enter into agreements
that would eventually lead to LSl's acquisition of 1144668 Ontario Ltd. in
exchange for the common stock of Life Sciences. As a path to this objective, LSI
and Numberco would initially form a joint venture to be equally owned by LSI and
Numberco to develop and market NASBA based tests for food home pathogens. With
the exception of contributing to the joint venture the technology necessary to
enable the joint venture to produce and sell a NASBA test for Listeria
monocytogenes, which is now an asset of Numberco, and Numberco's representation
on the governing body of the joint venture, the role of Numberco or the staff of
Genescape in the joint venture would be limited to that of advisory,
specifically with respect to advice regarding scientific operation of the
venture. LSI would bear all the legal, administrative and related costs to
establish, house and staff the venture's operations, and LSI would provide the
lead effort to attract grant and contract support from public and private U.S.
and international agencies with interest in food safety.

1144668 Ontario Ltd.                  June 15, 1999                       page 2

Our discussions with respect to funding of the development of individual test
products also provided that either of LSI or Numberco may pursue investments
from others or make direct investment in the joint venture or alternatively in
individual test products. In such cases additional equity in the joint venture,
or a royalty interest in a specific test product, would be awarded. With respect
to the already developed test for Listeria monocytogenes, if the test is at or
near the market-ready state and may be introduced without substantial added
development expense to be borne by LSI, Numberco would receive a royalty equal
to 15% of the net sales of the L. monocytogenes test kit.

With respect to the existing and any altered capital structure of Numberco, in
exchange for 50,000 shares of LSI common stock, the principals of Numberco would
grant LSI an option to purchase their holdings in Numberco for an additional
200,000 shares of the common stock of LSI. LSI's option would be exercisable
within 3 years of the date of the joint venture agreement at any time that the
market value of LSI common stock is sustained at or above $6.00 per share for 30
consecutive days, the market value being computed as one-half the sum of the
closing bid and asked prices of the LSI common stock. LSI's option to purchase
would also be alternatively exercised through LSI's payment to you of $1.2
million.

LSI's acquisition of an option to purchase Numberco recognizes that Cangene
Corporation owns a separate option to purchase a 25% interest in Numberco. This
option expires in September, 2000. With respect to the Cangene option, Numberco
and LSI are agreed that in the event Cangene elects to exercise its option, the
proceeds will flow to the current shareholders of Numberco, and LSI's option to
purchase Numberco becomes exercisable for the same consideration without regard
to the market value of the LSI common stock. Further, with respect to the LSI
option, prior to its exercise of same, the principals of Numberco may recover
for their own use such assets of Numberco as you elect, except for the NASBA
license for detection of food borne pathogens.

I trust that this communication accurately summarizes our discussions on this
matter to date and may serve as a basis for the development of definitive joint
venture and acquisition agreements. The agreement in principle represented by
this letter in intent is subject to the completion of our discussions, the
preparation, execution and delivery of definitive agreements, and the initiation
and completion of steps necessary to achieve compliance with applicable
securities laws. Please know that we at Life Sciences look forward to an
aggressive effort to fulfill the objectives described herein.

Sincerely,
LIFE SCIENCES, INC.

                         DEFINITION OF NASBA TECHNOLOGY


The term "NASBA" refers to Nucleic Acid Sequence Based Amplification, an
isothermal, transcription-based enzymatic nucleic acid amplification procedure
that can be applied to both RNA and DNA targets. The reaction process for RNA
analytes is depicted in Figure 1. The process is initiated by the annealing of
an oligonucleotide primer (designated P1) to the RNA target present in the
nucleic acid extract obtained from the test sample. The 3' end of the P1 primer
is complementary to the target analyte; the 5' end encodes the T7 RNA polymerase
promoter. After annealing, the reverse transcriptase activity of AMV-RT is
engaged and a cDNA copy of the RNA target is produced. The RNA portion of the
resulting hybrid molecule is hydrolyzed through the action of RNase H. This
permits the second primer (P2; sense), which is complementary to an upstream
portion of the RNA target, to anneal to the cDNA strand. This permits the
DNA-dependent DNA polymerase activity of AMV-RT to be engaged, producing a
double stranded cDNA copy of the original RNA analyte with a functional T7 RNA
polymerase promoter at one end. This promoter is then recognized by the T7 RNA
polymerase, which produces a large amount of anti-sense, single stranded RNA
transcripts corresponding to the original RNA target. These anti-sense RNA
transcripts can then serve as templates for the amplification process, however
the primers anneal in the reverse order. The entire NASBA process is isothermal
and is generally conducted at 41oC. For the amplification of DNA, the process is
the same as described in Figure 1, except that an initial heat denaturing step
(e.g., 100oC, 5 minutes) is required before the addition of the enzymes to the
reaction mix.

Both INNOVATIVE and LSI understand and agree that a NASBA reaction may be
performed in one or more other manners similar to, but different from, that
depicted in Figure 1. Where LSI can demonstrate by documentary evidence that it
has obtained license rights from Organon Teknika to employ such other methods
for performance of NASBA, then INNOVATIVE and LSI hereby agree that such other
methods of performing NASBA shall be included in the definition of NASBA.

November 21, 1999

Stephan S. Monroe, Ph.D.
Viral Gastroenteritis Section
Division of Viral and Rickettsial Diseases
MailStop G04
Centers for Disease Control and Prevention
1600 Clifton Rd., NE
Atlanta, Georgia 30333

Dear Dr. Monroe,

This letter is to confirm the understanding between Life Sciences, Inc. and the
Gastroenteritis Section of the Centers for Disease Control with respect to the
impending initiation of work on a NASBA-based test for detection of Norwalk-like
viruses prior to the execution of a definitive cooperative research and
development agreement (CRADA) between the parties.

As we discussed in our meeting on November 17, 1999, completion of the work
within a timeframe consistent with the mission of the Centers can be achieved
only if there are no significant delays in the start-up and pursuit of the
effort. At the same time, the dollar value and missed business opportunity
implications of Life Sciences' in-kind contributions to the early stages of the
effort are of sufficient magnitude to warrant the assurances requested by LSI in
this communication. In addition, because LSI's work on this effort must begin in
earnest on November 29, 1999 to meet the timing discussed, the prompt execution
of this letter approaches the imperative.

Further with respect to our November 17 discussions, Life Sciences represented
that it will provide with respect to the CRADA, at no cost to the Centers, the
items set out below as its base contribution to the effort described above:

                  (i)* The financial wherewithal to support a post-doctoral
         level scientist posted at the Centers, or at a location designated by
         the Centers, to work on this effort for the initial 12 months of the
         proposed CRADA. Funding at the same or adjusted level will be provided
         for a second 12-month period if the program objectives of the initial
         12 months are achieved. (This element of direct financial support,
         including employee benefit related overhead, is not expected to exceed
         $60,000 on an annual basis);

                  (ii) The transfer of a significant body of knowledge to CDC
         based scientists in the performance of nucleic acid sequence based
         amplification (NASBA); the design of primers necessary for
         amplification of RNA and DNA templates using NASBA; and the detection
         and analysis of the amplicons arising from these reactions using a
         proprietary technology.

Stephan S. Monroe, Ph.D.             November 21, 1999                   Page 2

                  (iii) A quantity of NASBA amplification and detection reagents
         (enzyme, primers, probe-labeled liposomes, etc.) and supplies
         sufficient to support this effort as ultimately defined in the scope of
         work of the proposed CRADA for the full term of the agreement;

                  (iv) A quantity (not to exceed 20 ) of specially modified,
         hand-held densitometers for low-cost, high-throughput qualitative and
         semi-quantitative assessment of NASBA reactions using a lateral flow
         cassette and a proprietary technology;

                  (v)* A quantity (not to exceed 3) of the LSI electrochemical
         NASBA analyzers for low-cost, high-throughput quantitative assessment
         of NASBA reactions using a proprietary technology;

                  (vi)* The use of an Organon Teknika automated nucleic acid
         extractor apparatus for the full term of the CRADA;

                  (vii)* The use of an Organon Teknika electrochemiluminescece
         detector for not less than the initial 6 months of the work effort;
         and.

                  (viii)* The assembly and support of a LSI-
         multiple-academic-center consortium to support the development of
         technology and methods for recovery of Norwalk-like virus/RNA templates
         in low copy number from non-patient related matrices to include water
         and food.

         *   To be provided only upon execution of the definitive CRADA.

While the language of the draft agreement provided to us contemplates that, at
the successful completion of the work effort to be described in the CRADA,
certain U.S. government-owned intellectual property will be licensed to LSI for
a range of applications, excluding vaccine development and production, it is our
expectation that certain additional assurances can be provided by your Section
in order to secure LSI's contributions during the period prior to the execution
of a definitive CRADA. Specifically, the Gastroenteritis Section agrees by
execution of this letter that during the period prior to execution of the
definitive agreement, and provided Life Sciences faithfully provides those
elements of the resources described above that are designated as appropriate to
the work to be carried out during the pre-agreement period, the Gastroenteritis
Section will collaborate exclusively with Life Sciences on development of the
NASBA-based test for Norwalk-like viruses contemplated in our discussions.

It is our current plan to begin synthesis of the required primers and probes for
amplification of certain of the Norwalk-like viruses and detection of both the
Astro and Norwalk-like viruses during this coming Thanksgiving week. This
timetable is necessitated by the absolute requirement that work on production of
the labeled liposomes be carried out at Cornell University beginning on November
29 as an element of the transfer of a licensed technology. If this schedule is
not met, it is doubtful that the detection components will be available to us

                                LETTER OF INTENT


                   LIFE SCIENCES WITH ACCIDENT PREVENTION PLUS
                          AND LIFE SCIENCES CORPORATION


This shall serve to confirm the understanding of the parties with respect to a
proposed Joint Venture by and between Life Sciences, Inc. ("LSI"), Accident
Prevention Plus, Inc. ("APP") and Life Sciences Corporation ("LIFE").

         WHEREAS, APP is the developer of an on-board vehicular data logger
("the Data Logger"); and

         WHEREAS, LSI has a continuing business relationship with LIFE pursuant
to which LSI is negotiating to act inter alia as the Florida and Georgia
marketer of an alcohol breathalyzer based vehicle ignition interlock program
("Breathalyzer Interlock") distributed by LIFE; and

         WHEREAS, the parties have conceived of the idea to integrate into a
single product (the "Integrated Product:") the Data Logger of APP, with LIFE's
Breathalyzer system and software for the Breathalyzer Interlock, to provide in
the commercial market a system able to monitor driving and motor vehicle
activity via the Data Logger when combined with other software programs; and

         WHEREAS, LIFE desires to join in this joint venture; and

         WHEREAS, LSI has committed to raising from outside sources the capital
necessary to fund the proposed Joint Venture

         NOW, THEREFORE, the parties hereto express their intent to establish to
a joint venture to create, market and distribute nationally and in other
countries the "Integrated Product," and establish and operate a Breathalyzer
Interlock provider service, minimally in the states of Georgia and Florida:

         1.       The joint venture shall be established in a separate
Delaware corporation ("Newco"). Each of LSI, APP and Life shall own 33-1/3% of
the capital stock. Newco shall have a Board of Directors of seven (7) persons,
two (2) appointed by APP, two (2) appointed by LSI, two (2) appointed by LIFE
and one (1) independent appointed by consent of all of the shareholders. The
affirmative vote of five (5) directors shall be required for any corporate
action by Newco.

                  (a)      LSI shall provide the capital or other resources
necessary for product research and development of the Integrated Product. APP
will contribute a license for the Data Logger with provisions for sublicenses by
Newco as well as sufficient product and parts to permit the research and




<PAGE>   2

development of the Integrated Product. It is estimated that the capital required
would be approximately Two Hundred and Fifty Thousand ($250,000) Dollars. The
maximum amount required of LSI for development of the Integrated Product shall
be Three Hundred and Fifty ($350,000) Dollars for the integrated product portion
of this venture.

                  (b)      LSI shall provide additional funding to Newco for
approximately $600,000 to be used for to build, establish, operate, and provide
installations, calibration, monitoring, service, removals, and collateral needs
to an Ignition Interlock Program in the states of Georgia and Florida
(approximately evenly divided between the 2 state interlock programs).

                           i.       This program will be owned by Newco, but
managed entirely by LIFE and its management, support staff, and contractors, and
LIFE shall be entitled to its costs of providing product, supplies and service,
and a reasonable ROI for its work. LIFE will provide the budgets needed for this
Georgia and Florida effort, and LSI will fund that budget as required for
implementation.

                           ii.      LIFE will maintain the accounting for these
2 programs, and report to NEWCO's Board on the program development as required.
LIFE will conduct these programs on a reasonable budget, which will not
sacrifice quality of service, and will be intended to provide statewide coverage
for each program as soon as practicable. All costs of doing business in these 2
state programs will be the responsibility of Newco, funded by LSI, using Life's
management, programs, and expertise. Newco will fund the monthly startup
requirements of each state program.

                           iii.     The programs shall be identified as LIFE
interlock programs, and/or Ignition Interlock Group of Georgia or Florida,
respectively (in the discretion of LIFE), and bear all the trademarks and
copyrights of a LIFE program (e.g., titles on reports to courts, probation and
administrators, IIG corporate logo, "authorized service center" logos, and
building signage), so that it can be identified as part of LIFE's national
interlock service program. LSI shall also provide the resources necessary to
combine certain computer software owned by LIFE in order to enable distributed
use of the complete In*CARS and administrative support software already
developed by LIFE. LIFE will continue to own its software programs. LIFE will
prepare and present its budget for start of the Georgia program within 120 days
of the funding requirements of LSI being met. If not funded so that the program




<PAGE>   3

can begin in Georgia by August 1, 2000, then LIFE may start the program through
other funding sources, and not be obligated to allow NEWCO to participate in the
ownership of the Georgia interlock program.

                           iv.      LIFE will receive a royalty-free license to
utilize the modified integrated product computer software and any modifications
or maintenance required on that software from time to time.

                           v.       Georgia and Florida will be the only
interlock states involved in this project, but LIFE will assist in marketing the
joint APP/LSI/LIFE breathalyzer/APP-product integrated project device
nationally, be responsible for supervising installation, calibration,
monitoring, training and maintenance of this project at its cost of providing
such services, on a budget and in a format agreed to by Newco.

                           vi.      The Parties will use their best efforts to
extend the sale of the of integrated product worldwide, but failing any such
extension each party shall remain free to engage in international sales of its
own products.

                  (c)      The parties shall work together to develop a more
precise description of the Integrated Product and of the intellectual property
being contribute to such Integrated Product by APP and LIFE. The parties will
also work together to identify and summarize technical constraints and other
elements of the research and development project for the Integrated product. If
either party becomes aware of any additional technology which would be useful or
appropriate for inclusion in the integrated product such party shall share the
information with the others.

                  (d)      APP has advised LSI of its awareness of certain
technology related to the detection of drowsiness of motor vehicle operators
being developed at Carnegie Mellon University ("CMU"). APP shall use its best
efforts to gain access to the drowsiness technology for the joint venture from
CMU. Newco shall be solely responsible for any royalty payable with respect to
such drowsiness technology, and Newco shall be solely responsible for
negotiating any such royalty arrangement.

                  (e)      LIFE shall provide Newco with the right to lease at
an agreed fee the "In Cars" program and any modifications that are required in
order to support the marketing of the Breathalyzer Interlock in the states of
Florida and Georgia. Modifications shall be part of the costs of providing the
program for which LIFE will be paid by NEWCO.

                  (f)      The Parties contemplate that equity capital of
between




<PAGE>   4

$3 and $5 Million will be required for the full business activities of Newco.
Any sale of equity capital shall be for the account of Newco and shall equally
dilute the interests of LSI, APP and LIFE.

         2.       It shall be the responsibility of APP to budget and man the
integration project, under the supervision of Alex Burns and Jean Paul Daveau.
In the event LSI elects to have the integration project carried out by persons
other than APP, LSI shall make available to APP lending in an amount up to One
Hundred Thousand ($100,000) Dollars under terms to be negotiated and APP shall
allocate a sufficient portion of the time of JP Daveau to direct the integration
project during the course of the integration effort. Such loan shall be made
available at the commencement the integration project. As security for the
repayment of such $100,000 loan, APP shall pledge with LSI its shares in Newco.
LSI shall retain such shares until it is either repaid directly by APP or, if
not repaid directly, until it receives a disproportionate share of the proceeds
from Newco to the extend of such unpaid loan amount, or until such lending is
repaid in full. LSI shall have the option to convert the loan into APP common
stock at a price per share to be negotiated by the parties prior to the
execution of the formal agreement, provided for hereinafter.

         If APP is engaged to carry out the integration project APP shall
receive a deposit of $50,000 against such work at the time it commences.

         3.       The estimated timetable for the completion of the integration
project is 8/1/00, provided however that if the work is proceeding the deadline
for completion of the integration project shall be extended up to June1, 2001,.
In the event the Integrated Product is not successfully developed on or prior to
the deadline prior, APP shall be released from the requirement to work
exclusively with Newco in the development of an integrated Data Logger /
Breathalyzer Interlock device, unless specifically extended by agreement of the
parties hereto. Likewise, if LSI has not funded the Georgia interlock program in
an agreed budget by August 1, 2000, LIFE shall be released from the requirement
to work exclusively with Newco in Georgia and may develop that program with
others. If LSI has not secured the funding for a Florida interlock program

developed, Newco shall have the exclusive license for the sale of the Integrated
Product and Newco shall purchase all Breathalyzer Interlock elements from Life,
and all Data Logger elements from APP.

                  (b)      In the event Newco elects to contract/license
production of the Integrated Product to others and such product incorporates
intellectual property from APP to Newco, APP will additionally receive a royalty
equal to Five (5%) Percent of the selling price of the product.

it has no objection thereto.

         6.       The formal agreement with respect to the matters set forth in
this Letter of Intent shall be executed on or before March 9, 2000. In the event
there is failure to execute a formal agreement, this Letter of Intent shall be

               Report of Independent Certified Public Accountants

Board of Directors of
Life Sciences, Inc.


We have audited the accompanying consolidated balance sheets of Life Sciences,
Inc. and Subsidiary as of May 31, 1999 and 1998, and the related consolidated
statements of operations, stockholders' equity, and cash flows for the years
then ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our 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 consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Life
Sciences, Inc. and Subsidiary as of May 31, 1999 and 1998, and the consolidated
results of their operations and their cash flows for the years then ended, in
conformity with generally accepted accounting principles.

The accompanying consolidated financial statements have been prepared assuming
that the Company will continue as a going concern. As shown in the consolidated
financial statements, the Company had an accumulated deficit of $3,290,599 at
May 31, 1999. The Company has historically relied on loans and advances from
related entities to fund its operations. While the Company's history of
operating losses raises substantial doubt about the Company's ability to
continue as a going concern, management's plans in regard to this matter are
described in Note 3. The consolidated financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

NOTE 1 - DESCRIPTION OF ORGANIZATION AND BUSINESS

Life Sciences, Inc. (the Company) is a biotechnology company with its primary
operations in the production and sale of molecular biology enzymes used in the
test tube synthesis of DNA and its manipulation in a variety of genetic
engineering applications. The Company specializes in enzyme products employed by
scientists to make genetic (DNA) sequences, which are utilized in basic research
and the genetic modification of plants, animals and other organisms. The Company
sells its molecular biology enzyme products directly to end users who perform
nucleic acid related research and product development at universities and
diagnostic and pharmaceutical manufacturers, primarily in the United States,
Europe and Asia. Sales to customers based in Europe and Asia accounted for
approximately 65% of net sales during fiscal year 1999. The Company also
utilizes independent distributors in Europe and Asia to distribute its products
in these regions of the world. Through a 50 percent subsidiary, the Company,
until 1998, also engaged in the incineration of biomedical waste.


NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A summary of the significant accounting policies consistently applied in the
preparation of the accompanying consolidated financial statements follows:

Principles of Consolidation

The consolidated financial statements include the accounts of Life Sciences,
Inc. and a 50 percent owned subsidiary. Since Life Sciences, Inc. is deemed to
have the financial controlling interest in the subsidiary, it has been
consolidated in the accompanying financial statements. The minority interest
reflected in the statements of operations represents the net loss of the
consolidated subsidiary allocable to the remaining 50 percent interest held by
independent shareholders. All significant intercompany accounts and transactions
have been eliminated in consolidation.

Use of Estimates

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

Cash Equivalents

The Company considers all highly liquid investments with an original maturity of
three months or less to be cash equivalents. There were no cash equivalents at
May 31, 1999 and 1998.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

Inventories

Inventories are stated at the lower of cost or market with cost determined on a
first-in, first-out (FIFO) method.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Prior
to January 1, 1981, depreciation and amortization are provided using the
straight-line method over the estimated useful service lives of the related
assets. After this date, property and equipment are depreciated using
accelerated methods that are used for federal income tax reporting.

Impairment of Long-Lived Assets

The Company evaluates the recoverability of its long-lived assets (including
intangibles) in accordance with Statement of Financial Accounting Standards No.
121 ("SFAS No. 121"), Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed Of. SFAS No. 121 requires long-lived assets to
be reviewed for impairment whenever circumstances indicate that the carrying
amount of an asset may not be recoverable. An impairment is recognized to the
extent the sum of undiscounted estimated future cash flows expected to result
from the use of the asset is less than the carrying value. No impairment exists
for all periods presented.

Revenue Recognition

The Company recognizes revenue when product is shipped to its customers.

Research and Development Costs

Expenditures relating to the development of new products and processes, as well
as significant refinements to existing products, are expensed as incurred.
Research and development expenses charged to operations amounted to $118,298 and
$89,284 for the years ended May 31, 1999 and 1998. Included in these amounts
were primarily payroll and related costs incurred to expand the Company's enzyme
products for a major customer.

Net Income (Loss) Per Common Share

Net income (loss) per common share, which represents both basic and diluted
earnings per share ("EPS"), is computed by dividing net income (loss) by the
weighted average common shares outstanding. The following table reconciles the
numerator and denominator of the basic and diluted EPS computation:

For the year ended May 31, 1999, options to purchase 480,000 shares of Common
Stock were outstanding during the year but were not included in the computation
of diluted earnings per share because the exercise prices of the options were
greater than the average market price of the Common Stock and, therefore, the
effect would be anti-dilutive. Basic loss per share is the same as the diluted
loss per share for the year ended May 31, 1998, since the Company experienced a
net loss for the year.

Stock-Based Compensation

The Company presents only the disclosure provisions of Statement of Financial
Accounting Standards No. 123, Accounting for Stock Based Compensation, and
recognizes stock-based compensation using the intrinsic value method of
accounting prescribed by APB Opinion No. 25, Accounting for Stock Issued to
Employees (Note 11). Under this method, compensation is recognized at the date
of grant by the amount that the fair value of the underlying stock exceeds the
exercise price.

Financial Instruments

The carrying amount of the Company's financial instruments, which include cash,
accounts receivable, accounts payable, accrued expenses and debt, approximate
fair value due to the short-term maturity of those instruments. The Company
considers the fixed and variable rate debt instruments to be representative of
current market interest rates and, accordingly, the recorded amounts approximate
their present fair market value.

Income Taxes

Deferred taxes are provided on the liability method whereby deferred tax assets
are recognized for deductible temporary differences, net operating losses and
tax credit carryforwards, and deferred tax liabilities are recognized for
taxable temporary differences. Temporary differences are the differences between
the reported amounts of assets and liabilities for financial reporting purposes
and their tax bases. Deferred tax assets are reduced by a valuation allowance
when, in the opinion of management, it is more likely than not that some portion
or all of the deferred tax assets will not be realized. Deferred tax assets and
liabilities are adjusted for the effect of changes in tax laws and rates on the
date of enactment.

Concentration of Credit Risk

The Company grants credit to customers who meet pre-established credit
requirements. The Company does not require collateral when trade credit is
granted to customers. Credit losses are provided for in the financial statements
and have been consistently within management's expectations. The allowance for
doubtful accounts related to accounts receivable at May 31, 1999 and 1998 was
approximately $5,000.


NOTE 3 - OPERATIONAL AND FUNDING MATTERS

The accompanying consolidated financial statements have been prepared in
conformity with generally accepted accounting principles, which contemplates
continuation of the Company as a going concern. Continuation of the Company as a
going concern contemplates the realization of assets, and settlement of
liabilities and commitments, in the normal course of business.

The Company had an accumulated deficit of $3,215,599 at May 31, 1999. The
Company has historically relied on loans and advances from related entities to
fund its operations. The financial statements do not include any adjustments
relating to the recoverability and classification of recorded asset amounts, or
amounts and classification of liabilities that might be necessary should the
Company be unable to continue in existence. The following commentary addresses
the Company's operations for the year ended May 31, 1999 and its plan to improve
future results.

Since 1994 the Company's aggregate loss of $1.7 million arose largely from the
Company's sustained effort to develop new products and services to offset
declines in revenues from the sale of its earlier anchor products, AMV reverse
transcriptase, and specific-pathogen-free (SPF) mice. In response to these
declining revenues, the Company ceased its sale of SPF mice in 1997 and, in a
further cost reduction effort in 1998, shut down a joint venture effort for
treatment of biomedical waste through thermal reduction.

                              May 31, 1999 and 1998


NOTE 3 - OPERATIONAL AND FUNDING MATTERS - CONTINUED

The Company's development efforts during this period focused on technologies for
rapid detection of biological and chemical contaminants in food, water, and
other environmental samples. The Company also undertook work to expand its
offering of enzyme products and develop new formulations of the enzymes to
address the needs of particular customers.

While revenues from the sale of enzymes were essentially unchanged between 1998
and 1999, sales of a new formulation of AMV reverse transcriptase and other
enzymes introduced in 1999 offset a nearly $200,000 decline in sales of enzymes
to Pacific Rim distributors. The new formulation of enzymes was adopted by a
major clinical diagnostics manufacturer for use as substrate in a line of
proprietary products for nucleic acid sequence based amplification (NASBA) based
diagnosis of HIV and other human diseases. This new product has fostered a
revival in the enzyme sector of the Company's operations, with sales of NASBA
enzymes expected by management to increase from $420,000 in 1999 to nearly $1
million in 2000. Sales of the Company's standard enzyme products to Pacific Rim
distributors rebounded in the second half of 1999, and the Company expects this
sales level to be sustained.

In addition to the NASBA enzyme mix currently being supplied to diagnostic
manufacturers, the Company will begin to produce in fiscal 2000 a dried NASBA
enzyme mix using a licensed, proprietary technology. Dried enzymes and other
components in NASBA based diagnostic kits permit the products to be transported
and stored in locations where next-day delivery of frozen products using dry ice
as a refrigerant and storage at deep-freeze temperatures may not be possible.
Additionally the shelf life of new products is extended by the use of dried test
kit components.

Using the same drying technology, the Company plans to increase its product
offering to include dried preparations of any of the nucleic acid modifying
enzymes used in molecular biology research. The availability of dried enzymes
for shipment and short term storage at ambient temperature is expected to
enhance the Company's ability to market its entire offering of enzyme products
to North American end users as well as to distributors worldwide, particularly
those that target their sales to developing Pacific Rim countries and Eastern
Europe.

The diagnostic tests for which the Company supplies NASBA enzymes are based on a
proprietary technology for amplification of DNA and RNA. The technology offers a
powerful method for rapid identification of viral and bacterial pathogens
associated with human disease. Because of management's belief that NASBA
technology is an equally robust tool for detection of pathogens in food,
drinking water and other environmental locations to include bio-warfare agents,
the Company has acquired licenses from Organon Teknika and others to enable the
Company to produce and sell NASBA based tests for detection of environmental
pathogens worldwide and the development and sale of diagnostic tests for
identification of certain clinical pathogens in defined, geographically
restricted regions. The Company expects to launch its initial NASBA based tests
for environmental diagnosis during fiscal year 2000.

NOTE 3 - OPERATIONAL AND FUNDING MATTERS - CONTINUED

To support this effort, the Company additionally licensed a proprietary
technology to support the development of field portable devices for rapid
analysis of the results of NASBA reactions. The NASBA detection system now
employed by the Company reduces the cost of associated instrumentation by more
than 80% and increases sample throughput by more than five fold. The technical
and cost advantages of the Company detection system are expected to jump-start
the Company's sale of NASBA based products in the molecular biology community.

The favorable cost and throughput related characteristics of the Company's
NASBA detection system also have attracted substantial interest on the part of
public health authorities in the United States and China. In collaboration with
an agency of the United States government, the Company has begun work on a
NASBA based test for Norwalk-like virus, a food borne pathogen that causes an
estimated 23 million annual cases of illness in the United States. With the
encouragement of Chinese public health agencies, the Company has investigated
the potential use of the Company's NASBA diagnostic system to monitor the
virus-load of HIV patients and potentially screen extremely large numbers of
individuals for the presence of the pathogens that cause HIV, hepatitis, and
other sexually transmitted diseases. The Company is presently seeking a capital
commitment of $6-$10 million for a China based joint venture that would carry
out the Company's plan to complete clinical trails in China on a low-cost NASBA
based test for virus load in HIV patients during calendar year 2000. If the
capital commitment is not obtained, the Chinese initiative will not be further
pursued. If the commitment is obtained, management believes that successful
completion of this initial clinical trial will be sufficient to attract the
additional investment required to develop and distribute a full line of NASBA
based human diagnostic products for sexually transmitted diseases throughout
China.

The expansion of the Company's product offering to include NASBA based tests
for the research market, test kits for waterborne and food borne pathogens and
dried enzyme preparations, requires a renewed focus on the North American,
end-user market. Additional marketing resources must be added to the Company's
staff to achieve this objective. Further, additional production staff and
capital equipment would be required to support larger outputs of enzymes and to
produce dried enzyme preparations. Management believes that the additional
expenditures of approximately $300,000 that would be required to support these
activities should be provided from cash generated from the Company's
operations.

Management intends to continue to operate the Company in a conservative manner
and to limit any short-term expansion (exclusive of the contemplated China
based joint venture) to that which can be funded by cash flows from current
operations. While management believes the Company will be able to operate
without interruption, it intends to continue discussions with potential
business partners that can potentially enhance the Company's product and market
position. However, no assurances can be given that the Company will be able to
operate without interruption.

During fiscal year 1999, the unsecured notes payable described above were
converted into shares of Common Stock and the accrued interest was forgiven
(see Note 9).

In addition, in May 1999, the corporate office land and building was sold and
the note payable and accrued interest were released by the holder (Note 9).


NOTE 9 - STOCKHOLDERS' EQUITY (DEFICIT)

In 1999, the Company completed a major restructuring plan by eliminating debt
totaling $2,528,148 consisting of principal of $1,613,985 and accrued interest
of $914,163. This restructuring plan greatly enhanced its financial position at
May 31, 1999.

Notes payable (principal only) to related parties totaling $568,828 were
converted to equity by the issuance of 1,399,927 shares of the Company's common
stock. A note payable to a related party totaling $186,082 was forgiven. In
addition, the accrued interest associated with these notes payable totaling
$914,163 at May 31, 1998 was forgiven by the parties.

NOTE 9 - STOCKHOLDERS' EQUITY (DEFICIT) - CONTINUED

In addition, the Company sold its land and building in two distinct
transactions. The first involved an unrelated third party, which bought a
portion of the Company's vacant land for $200,000 in cash. The second
transaction involved a related party who bought the remaining land and the
buildings housing the corporate and manufacturing headquarters, which was
immediately leased back to the Company under a five-year term without any
current provisions for renewal. The note payable (the principal only) totaling
$859,075 collateralized by the property was held by the related party who
purchased the property and was used as consideration in the transaction. As a
result, the note payable, which approximated the estimated fair value of the
property immediately before the sale, was deemed fully satisfied by the
transaction. The accrued interest related to this note payable was forgiven.

The notes had resulted from the related parties funding the Company's
operations over a period of time exceeding four to five years. Prior to 1999,
the intent of all parties was that the debt would be repaid. The obligations
were represented by formal notes bearing market interest rates and containing
other provisions. With the elimination of the related party debt in 1999, all
parties agreed that interest would not accrue subsequent to May 31, 1998.

For financial statement reporting purposes, the restructuring (exclusive of the
sale of a portion of the vacant land to an unrelated third party) is presented
as capital transactions reflecting the substance of the transactions with
parties under varying percentage of common ownership. Accordingly, the
forgiveness of the accrued interest and note payable of $914,163 and $186,082,
respectively, are reflected as additional paid-in capital and not as income in
the statement of operations. The difference of $756,475 between the balance on
the note payable and the basis in the related property of approximately
$102,600, is also presented as an additional paid-in capital and not as a gain
on sale in the statement of operations.

Leases

The Company leases its corporate offices from an entity owned by the Company's
President and Chairman and individuals related to the Company's President and
Chairman (Note 9). The lease expires in the year 2004, without any current
provisions for renewal, and provides for annual commitments of $90,000, subject
to adjustment to reflect current market rates.

Legal Proceedings

In October 1998, Imaging Science Technologies, Inc. filed an action in the
Pinellas County, Florida Circuit Court against the Company. The complaint seeks
unspecified damages based on allegations that the Company failed to return
confidential information to the Plaintiff and used such information for its own
purposes. The Company has denied the material allegations of the complaint. At
this time, management believes the Plaintiff's claims are without merit and the
ultimate resolution of this matter will not have a material effect on the
Company's financial position or results of operations.

Year 2000 Compliance

The Year 2000 issue relates to limitations in computer systems and applications
that may prevent proper recognition of the year 2000. The potential effect of
the Year 2000 issue on the Company and its vendors will not be fully
determinable until the Year 2000 and thereafter. If the Year 2000 modifications
are not properly completed either by the Company or entities with which the
Company conducts business, the Company's revenues and financial condition could
be adversely impacted.

The Company has identified its significant information technology systems that
could possibly be impacted by the Year 2000. The Company has been notified that
its accounting software packages and production system software are already
Year 2000 compliant.

The Year 2000 issue also provides for certification of Year 2000 compliance by
the Company's vendors. Such vendors provide biological resources used in the
production of enzymes. The Company could replace such vendors and related
products if it believes their state of Year 2000 readiness poses a risk to the
Company sufficient to warrant doing so. The Company does not anticipate any
difficulty in securing adequate replacements for such vendors or products.
Management does not anticipate significant disruptions in its operations as a
result of the turn of the century.

NOTE 11 - STOCK OPTIONS

The Board of Directors adopted a stock option plan under which incentive or
non-incentive stock options may be granted to directors, officers and key
employees. A total of 500,000 shares of Common Stock have been reserved for
issuance under the plan. The exercise price on options granted shall not be
less than the fair market value of the stock on the date of grant and will
expire no later than ten years from the date of grant. In the case of a
stockholder owning more than 10% of the outstanding stock of the Company, the
exercise price of an incentive option may not be less than 110% of the fair
market value of the stock on the date of grant, and such options will expire no
later than five years from the date of grant. Also, an aggregate fair market
value of the stock with respect to which incentive stock options are
exercisable for the first time by any individual in any calendar year may not
exceed $100,000. Options to purchase 270,000 shares of common stock were
outstanding under the terms of the 1990 plan and options to purchase 210,000
shares of common stock were granted in 1999 not within the terms of the 1990
plan. Additionally, at May 31, 1999, options to purchase 65,000 shares of
common stock were outstanding under stock option plans that have been
terminated.

The exercise price of each outstanding option equals the market price of the
Company's stock on the date of grant. Accordingly, no compensation cost has
been recognized for the plan. Had compensation cost for the plan been
determined based on the fair value of the options at the grant dates, the
Company's historical net loss and historical net loss per common share would
have been reduced to the pro forma amounts indicated below:

The fair value of each option grant is estimated on the date of grant using
Binomial options-pricing model with the following weighted average assumptions
used for grants in 1999 and 1998, respectively: no dividend yield, expected
volatility of 50%, risk-free interest rate of 6.0% and expected lives of 5
years.

NOTE 12 - DEFINED PENSION PLAN

In 1999, the Company adopted Statement of Financial Accounting Standards No.
132 ("SFAS No. 132"), Employers Disclosures about Pensions and Other
Postretirement Benefits. SFAS No. 132 standardizes the disclosure requirements
for pensions and other postretirement benefits, requires additional information
on changes in the benefit obligations and fair values of plan assets, and
eliminates certain disclosures that are no longer considered useful. The
adoption of SFAS No. 132 had no impact on the Company's financial position or
results of operations.

The Company sponsors a noncontributory defined benefit pension plan that covers
substantially all full-time employees. The plan provides for benefits to be
paid to eligible employees at retirement, based upon years of service with the
Company and compensation rates near retirement. Contributions to the plan
reflect benefits attributed to employees' services to date, as well as services
expected to be earned in the future. The Company's general funding policy is to
contribute amounts deductible for federal income tax purposes. Plan assets
primarily consist of common and preferred stock, investment grade corporate
bonds, and U.S. government obligations. The Company has the right to modify,
amend or terminate the plan.

The following table provides a reconciliation of the changes in the benefit
obligations and the fair value of the plan assets for the years ended May 31,
1999 and 1998 and statements of the funded status as of May 31, 1999 and 1998.

</TABLE>

At May 31, 1999 and 1998 the projected benefit obligation exceeds the fair
value of plan assets by approximately $150,000. As the accrued benefit cost
exceeds this amount in both years an additional minimum liability has not been
recognized.

The Company has not made a contribution to the Plan since April 1990. As a
result, the Plan is underfunded as defined by the rules and regulations of the
Internal Revenue Code. A minimum contribution of approximately $200,000 is
currently required to rectify this deficiency.

The assumptions used in the measurement of the Company's benefit obligations
are shown in the following table:
