                                     PART I


ITEM 1.   BUSINESS

OVERVIEW

         SpectRx is a medical biophotonics company that develops and
manufactures painless and bloodless alternatives to traditional medical
diagnostic and monitoring procedures. Medical biophotonics is the technology of
using light beams and other forms of energy to gain unique access to the human
body to diagnose and monitor medical conditions. The Company has developed a
non-invasive alternative to conventional tests for monitoring infant jaundice,
and is developing less invasive and painless alternatives than are currently
available for conventional diabetes detection, glucose monitoring and cancer
detection tests. The Company has entered into collaborative arrangements with
Respironics, Inc. ("Respironics") through its acquired business, Healthdyne
Technologies, Inc., Abbott Laboratories ("Abbott"), Roche Diagnostics Boehringer
Mannheim Corp. ("Roche Diagnostics") and Welch Allyn, Inc. ("Welch Allyn") to
facilitate the development, commercialization and introduction of its infant
jaundice, diabetes detection, glucose monitoring and cancer detection products,
respectively.

SPECTRX'S BUSINESS STRATEGY

          The Company's goal is to introduce products that reduce or eliminate
pain, are convenient to use and provide rapid results at the point of care,
thereby improving patient well being and reducing health care costs. To achieve
this objective, the Company is pursuing the following business strategy:

         -        Focus on Current Products. The Company intends to continue to
                  advance its current products to commercialization by (i)
                  leveraging the expertise of its collaborative partners, (ii)
                  seeking 510(k) clearance from the United States Food and Drug
                  Administration ("FDA") for these products where possible,
                  (iii) expanding its internal product development
                  capabilities, and (iv) developing its sales, marketing and
                  manufacturing capabilities. This includes the manufacturing
                  and marketing of its BiliChek(TM) system and the continued
                  development and introduction of the Company's diabetes
                  detection product.

         -        Develop Additional Products. Develop additional products from
                  the current product foundation. The Company believes that its
                  development activities in glucose monitoring and cancer
                  detection have significant promise for as many as four
                  additional product offerings that utilize the Company's
                  biophotonic technologies. The Company believes that its
                  diabetes detection product will lead to increased testing,
                  enlarging the market for glucose monitoring. The Company also
                  believes that the cancer detection products will be an
                  extension upon the technology used in the BiliChek(TM) and
                  diabetes detection products.

          -       Collaborate with Market Leaders. The Company has selectively
                  established collaborative arrangements with Abbott, Roche
                  Diagnostics, Respironics and Welch Allyn to develop and
                  commercialize its products. The Company intends to continue
                  selectively establishing strategic relationships with leading
                  companies, as appropriate, for the development,
                  commercialization and introduction of future products.

          -       Leverage Proprietary Technologies. The Company intends to
                  leverage its proprietary biophotonic technologies by
                  developing future products based on these technologies that
                  can provide cost effective, less invasive alternatives to
                  current diagnostic or monitoring products at the point of
                  care. For example, the Company believes its interstitial
                  fluid sampling technology may be applicable for monitoring
                  analytes other than glucose.

          -       Address Large Market Opportunities. The Company intends to
                  selectively develop future products for large markets in
                  which its products can ideally (i) apply for timely clearance
                  from the FDA, (ii) incorporate a disposable component and
                  (iii) qualify for third-party reimbursement.

INDUSTRY OVERVIEWS

INFANT JAUNDICE

Background

          Infant jaundice is a condition that primarily affects newborns within
the first three to ten days of life. If left untreated infant jaundice may, in
extreme cases (kernicterus), lead to brain damage or death. Jaundice is
characterized by a yellowing of the skin and eyes caused by an excess of
bilirubin in the body. Bilirubin is a normal waste product resulting from the
breakdown of red blood cells and is removed from the body by the liver. Prior
to birth, the bilirubin in an infant is processed by the mother's liver and
excreted. After birth, an infant must eliminate bilirubin without the mother's
help. It may take the infant's system several days to begin eliminating the
bilirubin faster than it is produced. Infants who are born prematurely, who are
underfed, or who belong to certain ethnic groups are at increased risk of
developing jaundice. The initial screening for jaundice is the observation of
yellow skin. This is a subjective determination prone to errors due to
differing skin colors and gestational ages. If a baby is selected for further
jaundice testing, the current procedure requires that a blood sample be
obtained from the infant, usually by lancing the infant's heel, which is a
traumatic process for the infant. Since jaundice normally presents in infants
36 to 72 hours after birth, infants who are sent home after a short hospital
stay pursuant to managed care guidelines in the United States are at risk
because the condition may not have presented prior to release.

The Infant Jaundice Screening and Monitoring Market

          Of the approximately four million newborns each year in the United
States, approximately 40-60% have recognizable jaundice. Annually,
approximately 1.7 million newborns receive at least one blood test for
bilirubin. Of those newborns tested, approximately 700,000 have elevated
bilirubin levels, and a portion of these newborns will receive additional
tests. The cost to the patient for a bilirubin test ranges from $22.25 to
$37.75; the laboratory processing cost usually ranges from $10.00-$12.00. Many
of those infants in the United States diagnosed with jaundice will undergo
phototherapy, a treatment that converts bilirubin into a water soluble form
that can be processed and eliminated from the infant's system. The Company
believes that the average newborn under active phototherapy treatment receives
three to four bilirubin monitoring tests.

The SpectRx Non-Invasive Infant Jaundice Product

          The Company's infant jaundice product, named the "BiliChek(TM)"
Non-Invasive Bilirubin Analyzer (sold internationally as BiliCheckTM) is based
upon reflection spectroscopy and measures bilirubin regardless of the patient's
skin color or gestational age. The product is designed to provide rapid,
point-of-care bilirubin measurements and to serve as an initial screening and
ongoing monitoring device. The Company believes that the BiliChek(TM) has the
potential to replace the painful heel stick procedure currently utilized.

          The design of the BiliChek(TM) consists of a hand held,
battery-operated instrument, which, when not in use, sits in a compact charger
base. This instrument incorporates a microspectrometer to collect spectroscopic
information from the skin and a proprietary, disposable calibration element,
BiliCal(TM). After calibration, the instrument is applied to the skin of the
infant for five applications, which generally takes less than one minute to
produce a measureable value. During this time the bilirubin level is measured
by collecting the light reflected from the skin and analyzing it using a
proprietary algorithm that adjusts for interfering factors that are present due
to skin color, gestational age and other factors.

         In 1998, the Company received ISO 9001/EN 46001 certification and was
granted the CE mark which allowed it to begin selling the BiliChek(TM)
internationally. In April 1998, the Company announced it had begun commercially
shipping BiliChek(TM) units to certain international distributors. The
BiliChek(TM) is currently being marketed in more than 60 countries worldwide. In
August 1998, the Company announced that a 510(k) premarket notification
submission was filed with the U.S. Food and Drug Administration (FDA) on behalf
of the BiliChek(TM) by Respironics (formerly Healthdyne Technologies). In March
1999, the Company announced that it had received clearance from the FDA for


                                      -3-
<PAGE>   4

Respironics to market the BiliChek(TM) in the U.S. Respironics commenced
marketing of the BiliChek(TM) in the United States after obtaining FDA
clearance. In September 1998, Atom Medical Corporation was named as distributor
of the BiliChek(TM) in the Japanese market. In November 1999 the Japanese
Ministry of Health and Welfare granted marketing clearance to Atom. In January
2000 Respironics reported it had filed a 510(k) premarket notification
application with the FDA for expanded claims for use of the BiliChek(TM) during
phototherapy.

         The Company's BiliChek(TM) was developed pursuant to a collaborative
arrangement with Respironics. Under the terms of the arrangement, SpectRx
developed and manufactures the product and Respironics paid and will continue
to pay certain costs associated with additional product developmental and
clinical trials. Respironics has been granted a license to market and sell the
product in the United States and Canada, while SpectRx retains the rights to
sell the product in all other geographic markets. Respironics retains a
significant degree of discretion regarding the timing of these activities and
the amount and quality of financial, personnel and other resources that they
devote to these activities. Accordingly, there can be no assurance that the
marketing schedules will be met, if at all.


DIABETES

Background

          Diabetes is a major health care problem which, according to the World
Health Organization, is estimated to affect 100 million people worldwide by the
year 2000. If undiagnosed and untreated, diabetes can lead to severe medical
complications over time, including blindness, loss of kidney function, nerve
degeneration, and cardiovascular disease. Diabetes is the sixth leading cause
of death by disease in the United States and is estimated to cost the American
economy over $110 billion annually, including indirect costs such as lost
productivity.

          Diabetes occurs when the body does not produce sufficient levels of,
or effectively utilize, insulin, a hormone that regulates the metabolism
(breakdown) of glucose. Glucose levels in the blood must be within a specific
concentration range to ensure proper cellular function and health. Insulin
deficiency results in an abnormally high blood glucose concentration, which
causes protein glycation throughout the body, impairs the ability of cells to
intake glucose and has other adverse effects. In Type I (insulin-dependent
juvenile-onset) diabetes, which affects from 5% to 10% of all people with
diagnosed diabetes, the cells that make insulin have been destroyed. Type I
diabetes is treated with daily insulin injections. In the more prevalent form
of diabetes, Type II (non-insulin-dependent adult-onset) diabetes, the insulin
producing cells are unable to produce enough insulin to compensate for the
patient's poor sensitivity to the hormone in glucose-using tissues such as
skeletal muscle (a condition called insulin resistance). Type II diabetes is
initially managed with proper diet, exercise and oral medication. Based on
statistics published by the National Institutes of Health the Company estimates
that approximately 50% of Type II diabetics will eventually require insulin
therapy.

The Diabetes Detection Market

          The American Diabetes Association (the "ADA") estimates that
approximately 16 million people in the United States have diabetes, but only
10.3 million have been diagnosed with the disease. The long term health care
costs of a diabetic patient can be substantially reduced if the patient can be
diagnosed in the early stages of the disease. Early diagnosis allows glucose
levels to be monitored and properly controlled, thereby reducing complications
that result from long term exposure to elevated glucose levels. These
complications include diabetic retinopathy, kidney disease, nerve degeneration,
and cardiovascular disease. Currently, approximately 798,000 new cases of
diabetes are diagnosed each year in the United States, and many of those
diagnosed have complications that generally appear eight to ten years after
onset of the disease. The Company believes that the low rate of diabetes
diagnosis and the failure in many cases to diagnose the disease prior to the
onset of complications is due primarily to the lack of a convenient and
accurate diabetes detection test. In June 1997, the ADA altered its
recommendation for diabetes detection to increase the recommended level of
screening for all adults over 45 years old to every three years, which the
Company believes will increase market spending.


                                      -4-
<PAGE>   5

          There are several diabetes detection tests in use today. The diabetes
detection procedure recommended by the ADA is the blood-based fasting plasma
glucose test. This test is difficult and inconvenient to administer because it
requires the patient to fast for eight hours prior to the drawing of blood, and
because the blood sample is usually sent to a laboratory for analysis, which
delays the receipt by the patient of the test results. Current methods for
diabetes detection that utilize random finger stick blood glucose tests are no
longer recommended by the ADA because the random nature of the tests results in
an unacceptably low level of sensitivity (i.e., the ability to correctly
determine that a particular person has diabetes) and specificity (i.e., the
ability to correctly determine that a particular person does not have
diabetes). Glucose urine test products, which are available over-the-counter,
have an even lower test sensitivity and specificity and are not recommended for
screening by the ADA. The low levels of sensitivity and specificity in both the
random finger stick blood glucose test and the glucose urine test result in
cases of both undetected diabetes, which can prevent early treatment of the
disease in such cases, and false indications of diabetes, which can cause
patients to incur the expense of, and devote the time for, needless additional
testing.

The SpectRx Non-Invasive Diabetes Detection Product (The Accu-Chek(TM)
D-Tector(TM))

          The SpectRx non-invasive diabetes detection product being developed
by SpectRx and Roche is designed to detect and measure fluorescence in the lens
of the eye and evaluate that measurement using the Company's proprietary
algorithm. An abnormally high level of fluorescence in the lens of the eye may
be indicative of prolonged exposure to high levels of glucose due to diabetes.
A measurement indicating a patient is likely to have diabetes could be
confirmed by subsequent testing using conventional blood-based diagnostics. The
performance of the diabetes detection product has been shown to be comparable
to that of the blood-based screening test. Unlike the blood based tests,
however, the SpectRx diabetes detection product is painless, would provide the
patient with test results in less than a minute at the point of care, and would
not require the patient to fast for eight hours prior to administration of the
test.

          The Company's non-invasive diabetes detection product is designed to
be simple and painless to use and to produce accurate point-of-care results in
a very short period of time. The Company believes that such a method of
diabetes detection is likely to become as prevalent as glaucoma testing, which
is regularly performed during eye exams. Thus, the Company believes that the
product may result in increased diagnoses of the approximately 50 million
undiagnosed diabetics worldwide, including the approximately 5.5 million in the
United States. For this reason, the Company believes that its non-invasive
diabetes detection product presents a substantial opportunity to identify new
patients who can benefit from proper treatment thereby reducing incidence of
complications and their associated cost.

          The diabetes detection instrument, trademarked Accu-Chek(TM)
D-Tector(TM), is designed as a compact instrument that will meet the space
requirements of optometrists' and physicians' offices and will also be suitable
for retail establishments such as pharmacies. To use the device, the individual
looks into the instrument while placing his or her head against a rest. The
individual is instructed to look at a fixed light as the instrument locates the
eye and automatically tracks the pupil opening. The device measures
fluorescence in the lens of the eye using a low-intensity blue light. The
results of the analysis will indicate either that the patient should undergo
further diagnostic testing or that there is no indication of diabetes. In a
pilot study of more than 1,300 subjects (both diabetics and non-diabetics)
conducted by Roche Diagnostics, an early stage prototype of the Company's
diabetes detection product demonstrated an ability to detect diabetes.

         The Company is in the process of final testing and manufacturing
ramp-up of the product. In December 1998, a 510(k) premarket notification
submission was filed with the U.S. Food and Drug Administration by Roche
Diagnostics on behalf of the SpectRx non-invasive diabetes detection product.
That application was withdrawn in June 1999. In June 1999 Roche reported that
the FDA required a PMA approval process for the device and began the filing
process. We expect the Accu-Chek(TM) D-Tector(TM) to be reviewed as an expedited
PMA. In addition, Roche Diagnostics retains a significant degree of discretion
regarding the timing of these activities and the amount and quality of
financial, personnel and other resources that it devotes to these activities.
Accordingly, there can be no assurance that the production or regulatory
approval will occur.


                                      -5-
<PAGE>   6


          The Company has entered into a collaboration agreement with Roche
Diagnostics, as a result the Company has granted Roche Diagnostics an exclusive
worldwide license to sell and market the Company's non-invasive diabetes
detection product. The Company receives development milestone payments and
expects to receive a manufacturing profit on products sold to Roche
Diagnostics. Roche Diagnostics is responsible for conducting clinical testing,
obtaining regulatory approvals for, and the marketing, distribution and sales
of the Accu-Chek(TM) D-Tector(TM). In 1999 the Company received development
milestones for a total of $987,000 from Roche.

The Glucose Monitoring Market

          People with diabetes have difficulty achieving optimal glucose
control. For proper glucose control, each insulin injection, or other form of
medication, should be adjusted to reflect the person's current blood glucose
concentration, carbohydrate consumption, exercise pattern, stress or other
illness. Accordingly, personal glucose monitoring products have become critical
in managing diabetes by allowing diabetics to measure their glucose levels in
order to adjust their diet, exercise and use of oral medication or insulin to
maintain proper blood glucose levels.

          In June 1993, the National Institutes of Health announced the results
of the Diabetes Control and Complications Trial ("DCCT"). This long term study
of approximately 1,400 people with Type I diabetes confirmed the importance of
glucose control as a determinant of long term risk of degenerative
complications. The data from the DCCT demonstrated that the risk of
degenerative complications is significantly reduced if blood glucose
concentrations in people with Type I diabetes can be brought closer to the
concentrations measured in non-diabetic individuals. For example, the DCCT
study demonstrated that the risk of complications of diabetic retinopathy, the
leading cause of blindness in the United States, could be reduced up to 76%
through proper glucose control. The DCCT panel recommended that Type I
diabetics measure their blood glucose four times per day in order to maintain
proper control over their glucose levels. Although the DCCT study involved
people with Type I diabetes only, a similar Japanese study on Type II diabetics
supports the conclusion of the DCCT study that maintaining low average glucose
levels reduces the risks of complications associated with diabetes.

          Because glucose monitoring is an important part of the every day life
of the world's diagnosed diabetics, the personal glucose monitoring market is
substantial. The Company believes that the worldwide market for glucose
monitoring products at manufacturers' price levels is approximately $3.0
billion annually and is growing at approximately 12%-18% per year. The North
American market for such products was approximately $1.0 billion in 1996. The
Company believes that the market for personal glucose monitoring products is
driven by four main factors: 1) an aging population; 2) the realization that
tight glucose control dramatically reduces the risk of complications; 3) the
availability of third-party reimbursement in developed nations; and 4) the
promotion and increased availability of glucose monitoring products. It is
estimated that diabetics currently monitor their glucose on average less than
twice a day instead of the DCCT recommendation of four times per day. The
Company believes that the pain, inconvenience and cost associated with
conventional finger stick blood glucose monitoring systems is the primary
reason that most people with diabetes fail to comply with the recommendations
of the DCCT panel. The Company believes that greater awareness of the benefit
of frequent self-monitoring and less painful, more convenient monitoring
products could significantly increase the global market. Currently, no
non-invasive glucose monitoring systems are commercially available in the U.S.

          Glucose monitoring products have evolved rapidly over time. Various
factors have allowed new entrants to establish market share in the glucose
monitoring product market, including technological advances, broader product
distribution and increased patient awareness of product innovations. These
factors have also expanded the overall size of the market for glucose
monitoring products.

          Current commercially available glucose monitoring systems are painful
and inconvenient. These systems require that a blood sample be obtained from a
patient, applied to a disposable test strip and then measured for glucose
concentrations using a battery-powered, handheld monitor. Under these systems,
the blood sample is usually obtained from a patient's fingertip because of the
high concentration of capillaries at this site and because the blood produced
at the fingertip can most easily be applied directly to test strips used in
such devices. These systems typically require the patient to complete the
following steps: insert the disposable test strip into the meter, lance the
finger, apply the drop of


                                      -6-
<PAGE>   7

blood to the test strip and wait for the meter to display the results. Because
nerve endings are concentrated in the fingertips, this sampling process can be
painful. The level of patient discomfort is compounded by the fact that the
fingertips offer a limited surface area from which to obtain a blood sample.
Thus, the patient can be required to repeatedly sample from the same site,
eventually resulting in callouses. In addition, applying the drop of blood to
the test strip is difficult for those diabetics who have lost dexterity in
their extremities due to nerve degeneration.

The SpectRx Glucose Monitoring Products

          The Company is developing glucose monitoring products that utilize
the Company's proprietary interstitial fluid sampling technology that will
allow people with diabetes to easily and accurately measure their glucose
levels. Interstitial fluid is an extracellular fluid that is prevalent
throughout the body just beneath the skin. Interstitial fluid is the means by
which proteins and chemicals, including glucose, pass between capillaries and
cells. Studies based on the Company's and independent research have indicated
that interstitial fluid glucose levels correlate closely with blood glucose
levels. The Company believes that using interstitial fluid to assay glucose
levels is more efficient than using blood because it is free of interferences
such as red blood cells, which must often be separated from the plasma prior to
measurement. SpectRx's glucose monitoring products use the Company's
microporation technology to collect a sample of interstitial fluid. This
interstitial fluid sample may be measured once in a single-use application, or
a stream of interstitial fluid may be repeatedly measured for a continuous
monitoring application. Products using either sampling methodology are intended
to measure the glucose concentration of the interstitial fluid using disposable
assay technology. Because the Company's glucose monitoring products are
designed to obtain a sample of interstitial fluid from the outermost layers of
the skin and do not require a blood sample, their use does not stimulate pain
sensors and capillaries found in the deeper layers of skin and is thus free of
the pain and blood involved in conventional finger stick assaying techniques.

          The Company initially focused its research effort in the area of
single use glucose monitoring in collaboration with Abbott. Since the fall of
1998 SpectRx has focused its research efforts on applications in the continuous
monitoring area. In November 1999, the Company entered into an amendment to its
agreement with Abbott to include continuous monitoring products. The primary
focus of the Abbott/SpectRx collaboration is currently upon the continuous
monitoring product.

Continuous Glucose Monitoring Product

          During the course of research and development of its single-use
interstitial fluid-based glucose monitoring product, the Company discovered a
technique which allows for continuous monitoring of glucose. By applying a
constant state of low-level vacuum to an array of micropores, a stream of
interstitial fluid is produced. This stream of interstitial fluid may be passed
over a sensor which measures the glucose concentration periodically providing
the patient with multiple readings. Feasibility data generated by the company
in 1998 indicates that an array of micropores may be kept viable for up to
three days. A second feasibility study showed that the concentration of
interstitial fluid glucose continued to correlate to the concentration of blood
glucose during a three day period.

          The product concept of the continuous glucose monitoring product
consists of a disposable patch electronically connected to a beeper-sized
meter. The patch would be placed over a small array of micropores created on
the body. This array could be placed in a number of locations, but the current
concept would have it placed on the torso. The patch would be designed to
eliminate spent interstitial fluid. The meter would be worn on a belt or hidden
under clothing. The system would collect a new glucose reading every 10 to 15
minutes which would be recorded by the meter and presented on the meter's
display. The stored information would be capable of being downloaded for
analysis. The meter could also indicate if the current reading is higher or
lower than any previous reading, showing a trend. The meter would also be
capable of indicating high or low glucose levels via an alarm. For convenience,
the umbilical would be detachable so that the patient may bathe or engage in
other activities, then reattach the umbilical and resume monitoring the stream
of interstitial fluid. In June 1999, at the American Diabetes Association
meeting, the Company publicly demonstrated an integrated prototype capable of
measuring glucose concentration in a stream of interstitial fluid.


                                      -7-

          In October 1999, the Company received a grant of $292,000 from the
Centers for Disease Control to adapt its continuous glucose monitoring
technology to monitor levels of children and the elderly.

         In November 1999, the Company and Abbott entered into an amendment of
the agreement signed in 1996. The primary focus of the amendment was to include
the continuous glucose monitoring research, development and commercialization
effort with the agreement between SpectRx and Abbott. It also included potential
manufacturing by SpectRx and other potential collaborations with Abbott. In
addition, SpectRx issued redeemable, convertible preferred stock to Abbott for
$5,250,000 in conjunction with the signing of the amendment.

         The research and development is focused on the integration of the
Company's microporation technology, fluid management and the glucose assay
technology into a prototype device. The Company expects prototype development to
be followed by clinical trials and a regulatory submission. Unexpected problems,
however, may arise during the development and regulatory approval processes. In
addition, Abbott retains a significant degree of discretion regarding the timing
of these activities and the amount and quality of financial, personnel and other
resources that it devotes to these activities. Accordingly, there can be no
assurance that these events will occur.

Single-use Glucose Monitoring Product

          The single-use glucose monitoring product is expected to be comprised
of a small, hand held battery-powered, monitoring device and a proprietary,
disposable assay cartridge. The monitoring device will be placed on the skin,
and a laser or other suitable energy source mounted in the housing will be
directed onto the skin. When activated, an array of micropores will be
painlessly created in the outermost layer of skin, the stratum corneum. The
Company believes the creation of micropores will not damage adjacent tissue or
penetrate deeply enough to reach the capillary bed or nerve layer below the
stratum corneum. The Company anticipates that the device will have a
proprietary mechanism that will force the interstitial fluid out of the
micropores and into the disposable cartridge. When the assay cartridge is full
and the interstitial fluid has been analyzed, the results will appear on a
display.

          In January 1996, the Company undertook a pilot study of 10 subjects
(six diabetics and four nondiabetics) under a protocol reviewed and approved by
the Georgia Baptist Medical Center. The study was designed to evaluate the
correlation between results obtained using early stage prototypes of the
Company's glucose monitoring product and a leading conventional personal blood
glucose monitoring system. The study compared the glucose levels in
interstitial fluid and blood of the 10 subjects who were each administered 75
grams of glucose. The study, which yielded a total of 876 glucose measurements
(438 contemporaneous measurements of interstitial fluid and blood), produced a
correlation coefficient of 0.96 between glucose levels in interstitial fluid
and blood.

          In October 1996, the Company entered into a collaborative arrangement
with Abbott for the development and commercialization of the Company's glucose
monitoring products. Pursuant to the arrangement, the Company granted Abbott an
exclusive worldwide license for the Company's single use glucose monitoring
product and other related glucose monitoring devices in all countries except
Singapore and the Netherlands, where the license is non-exclusive. Pursuant to
the terms of the collaborative arrangement, Abbott agreed to pay all costs
associated with a joint research and development program, to make certain
milestone payments to the Company and to pay the Company a royalty based on net
sales. Abbott will also be responsible for conducting clinical trials,
obtaining regulatory approval for and manufacturing, marketing, distributing,
and selling the products covered by the arrangement. In addition, Abbott made a
$3 million equity investment in the Company in 1996 whereby it purchased
500,000 shares of Series C Preferred Stock which converted into 357,143 shares
of Common Stock upon the Company's initial public offering.

          The Company conducted research on the single use glucose monitoring
product through the third quarter of 1998. At that point in time that research
work was transferred to Abbott. Abbott is currently responsible for the research
program for single use glucose monitoring. The focus of that research will be to
produce methodologies that will permit collection of interstitial fluid at a
minimum volume level, and within a specified time, on a universal basis within
the target diabetic population. Abbott retains a significant degree of
discretion regarding the timing of these activities and the amount and quality
of financial, personnel and other resources that it devotes to these activities.
Accordingly, there can be no assurance that these events will occur.

NON-INVASIVE CANCER DETECTION

Background

         According to the American Cancer Society, cancer is a group of many
related diseases. All forms of cancer involve out-of-control growth and spread
of abnormal cells. Normal body cells grow, divide, and die in an orderly
fashion. Cancer cells, however, continue to grow and divide, and can spread to
other parts of the body. In America, half of all men and one-third of all women
will develop cancer during their lifetimes. According to the Society, the
sooner a cancer is found, and the sooner treatment begins, the better a
patient's chances are of a cure.

Cervical Cancer

         Cervical cancer is a cancer which begins in the lining of the cervix
(the lower part of the uterus) which may spread to other parts of the body if
left untreated. Cervical cancers form over time. There is generally a gradual
change from a normal cervix to cervix with precancer cells to cervical cancer.
For some women, precancerous changes may go away without any treatment. While
the majority of precancerous changes do not advance to cancer, if these
precancers are treated, true cancers can be prevented. The Pap smear, where a
sample of cervical tissue is placed on a slide and observed in a laboratory, is
the most common form of cervical cancer screening.

Cervical Cancer Market

         The American Cancer Society estimates that during 1999, about 12,800
cases of invasive cervical cancer will be diagnosed in the United States.
Cervical cancer is the ninth most deadly cancer in the U.S. with 4,800 deaths
predicted in 1999. According to published data, cervical cancer results in
approximately 190,000 deaths annually worldwide with 371,000 new cases reported
each year.

         The major market opportunities are in screening and diagnosis. Since
the introduction of better screening and diagnosis methods, the number of
cervical cancer deaths in the U.S. has declined dramatically. The main reason
for this change is the increased use of the Pap smear screening test. However
the Pap smear screening test has a wide variation in sensitivity (11% to 99%)
and specificity (14% to 97%), according to a meta-analysis of Pap test accuracy
published in the American Journal of Epidemiology, Vol. 141, No. 7, 1995.
Approximately 55 million Pap tests are given annually in the U.S. and Europe.
The average price of a Pap test in the U.S. is $26. New technologies improving
the sensitivity and specificity of pap smear screening have recently been
introduced and are finding acceptance in the market place.

         The standard for cervical cancer diagnosis, after screening, is a
visual examination of the cervix using a Colposcope followed by a biopsy. This
method looks for visual morphological changes attributable to cancer. There are
approximately two million Colposcope examinations annually in the U.S. and
Europe. The average cost of a Colposcope examination in the U.S. is $185.

Non-invasive Cervical Cancer Product

         The Company, in collaboration with Welch Allyn, is developing a
non-invasive cervical cancer detection product. The product is based on
SpectRx's proprietary biophotonic technology and the intended design is
expected to identify cancers and precancers painlessly, non-invasively and at
the point of care by shining light onto the cervix, then analyzing the light
reflected from the cervix. The information presented by the reflected light
will be used to produce a map or image of diseased tissue. Consequently, this
test, unlike the Pap smear test or biopsy, preserves the perspective and
positional information of disease on the cervix, allowing for more accurate
diagnosis. The SpectRx/Welch-Allyn product, in addition to detecting the
morphological changes, is also expected to detect the biochemical changes that
precede the development of visual lesions. In this way the cancer is detected
early in its development thereby increasing the chances of effective treatment.
The product is expected to incorporate a calibration disposable.

         During 1999, the Company conducted human clinical feasibility studies
of laboratory prototypes. In December 1999, the Company concluded the
feasibility studies and received a $700,000 milestone from Welch Allyn.
As a result the program moved into the development/engineering phase.


                                      -9-
<PAGE>   10

         The feasibility clinical studies were conducted at three U.S. centers
and resulted in 252 enrolled patient tests. The prototype devices effectively
differentiated cancerous and precancerous lesions from normal tissue and other
lesions with sensitivity from the three studies ranging from 89% to 100% (0% to
11% false negative rate) and specificity ranging from 80% to 89% (11% to 20%
false positive rate). In contrast, for patients where Pap test data could be
obtained, the Pap test classified 30% of cancerous and precancerous lesions as
normal or infection for a sensitivity of 70% (30% false negative rate), with a
corresponding specificity of 72% (28% false positive rate). The majority of the
cancerous and precancerous lesions missed by the Pap test were accurately
classified by the SpectRx test as precancerous.

         The Company expects prototype development to be followed by pivotal
clinical trials and a regulatory submission. Unexpected problems, however, may
arise during the development and regulatory approval processes. In addition,
Welch Allyn retains a significant degree of discretion regarding the timing of
these activities and the amount and quality of financial, personnel and other
resources that it devotes to these activities. Accordingly, there can be no
assurance that these events will occur.



COLLABORATIVE ARRANGEMENTS

          The Company's business strategy for the development, clinical
testing, regulatory approval, manufacturing, and commercialization of its
products depends upon the Company's ability to selectively enter into and
maintain collaborative arrangements with leading medical device companies. The
Company has been successful in its history in developing such strategic
relationships. The Company currently has collaborative arrangements with
Abbott, Roche Diagnostics, Respironics and Welch Allyn. The Company is, to
varying degrees, dependent upon its collaborative partners for the development,
clinical testing, regulatory approval, manufacturing, and commercialization of
its products.

Respironics
          In June 1996, SpectRx entered into a Purchasing and Licensing
Agreement with Healthdyne Technologies, Inc., which was later acquired by
Respironics (the "Respironics Agreement"). This agreement was amended October
21, 1998. Pursuant to the Respironics Agreement, Respironics is responsible for
clinical trials, the regulatory approval process and sale of the BiliChek(TM)
in the United States and Canada. The Company retains manufacturing rights and
is responsible for the regulatory approval process and sale of the infant
jaundice product outside of the United States and Canada. Under the Respironics
Agreement, the Company receives from Respironics licensing fees and a
manufacturing profit on products sold to Respironics and shares any profit from
the sales of disposables by Respironics. Respironics receives an exclusive
license for the United States and Canada (i) to use and sell instruments for
non-invasive bilirubin measurement ("Instruments"), (ii) to use and sell
disposable probes, tips or other devices which, when used with Instruments,
measure bilirubin levels ("Disposables") and items accessory to and not
necessary for the operation of Instruments or Disposables ("Accessories"), and
(iii) to make Instruments, Disposables and/or Accessories (collectively,
"Licensed Products"). Unless SpectRx is unable to supply Licensed Products,
Respironics must purchase its requirements for Licensed Products from SpectRx.
Respironics has agreed to pay SpectRx's cost for manufacturing each Licensed
Product. Respironics and SpectRx then share equally the margin earned on the
sale of Licensed Products. In order to maintain license exclusivity,
Respironics has agreed to purchase from SpectRx certain minimum amounts of
Licensed Products or pay a royalty to SpectRx for an equivalent number of
Licensed Products. In the event that SpectRx is unable to supply Licensed
Products, Respironics receives a license to manufacture the Licensed Products
and pays a royalty to SpectRx on sales of Licensed Products.

          SpectRx has granted to Respironics the exclusive option to acquire an
exclusive license for the United States and Canada, on terms substantially
similar to those contained in the Respironics Agreement, with respect to any
new intellectual property that comes into existence after the effective date of
the Respironics Agreement, which covers devices that would compete, directly or
indirectly, with the Licensed Products and for which SpectRx has the right and
authority to grant licenses. In such event, Respironics has agreed to reimburse
SpectRx for one-half of SpectRx's cost to develop and commercialize such
product, in lieu of paying any license fees. If Respironics fails to exercise
such option,


                                     -10-
<PAGE>   11

SpectRx may license such intellectual property to any third party on terms no
more favorable than those offered to Respironics.

          The Respironics Agreement remains in effect for the longer of fifteen
years or until the expiration date of the last licensed patent to expire. Upon
expiration of the Respironics Agreement, Respironics has the option to renew
the Respironics Agreement for additional fifteen year terms indefinitely.
Respironics also has the right to terminate the Respironics Agreement without
cause upon not less than 30 days' written notice to the Company.

Roche Diagnostics

          In December 1994, SpectRx entered into a Development and License
Agreement with Boehringer Mannheim Corp. (which has since merged with Roche
Diagnostics) with respect to a non-invasive instrument that measures changes in
the lens of the human eye for the purpose of detecting diabetes. The agreement
was superceded by a new Development and License Agreement (the "Development
Agreement") between SpectRx and Roche in June 1999. Pursuant to the Development
Agreement, SpectRx has granted to Roche Diagnostics an exclusive, worldwide
license to sell and market the Company's diabetes detection product. SpectRx
receives development milestone payments from Roche Diagnostics pursuant to the
Development Agreement. The Development Agreement remains exclusive for so long
as Roche Diagnostics meets certain minimum volume purchase requirements set
forth in the Supply Agreement with Roche Diagnostics (discussed below). The
Development Agreement may be terminated at any time by Roche Diagnostics upon
written notice to SpectRx.

          In January 1996, Roche Diagnostics and SpectRx entered into a Supply
Agreement for the supply by SpectRx to Roche Diagnostics of the Company's
diabetes detection product. This agreement was also superceded by a new Supply
Agreement (the "Supply Agreement") in June 1999. Roche Diagnostics 's purchase
price for the Company's diabetes detection product is calculated pursuant to a
formula based on a gross margin. Roche Diagnostics is required to meet minimum
annual purchase requirements for the diabetes detection product each year or
Roche Diagnostics forfeits its exclusivity under the marketing license granted
in the Development Agreement. The term of the Supply Agreement is coincident
with the term of the Development Agreement. Roche Diagnostics may terminate the
Supply Agreement for material breach (including a failure to supply adequate
requirements) of the agreement by the Company, which breach remains unremedied
for 30 days after notice to the Company and in which case Roche Diagnostics is
deemed to have acquired a manufacturing license under the Development
Agreement. If Roche Diagnostics acquires this manufacturing license, it must
pay royalties to SpectRx on Roche Diagnostics sales of the diabetes detection
product. SpectRx would retain the right to reacquire the manufacturing license.
During the term of the Supply Agreement, SpectRx cannot enter into any
agreement to develop or manufacture a non-invasive diabetes detection
instrument using the same or similar technology as used in the Company's
diabetes detection product other than with Roche Diagnostics affiliates. Roche
Diagnostics is not restricted from pursuing the development of a diabetes
detection instrument with another party.

Abbott Laboratories

          In October 1996, SpectRx entered into a Research & Development and
License Agreement with Abbott for the development and commercialization of the
Company's glucose monitoring technology in the field of extracting interstitial
fluid samples for glucose monitoring (the "Field"). In November 1999, SpectRx
and Abbott entered into an amendment of the Research Development and License
Agreement which included specific terms related to the continuous monitoring
program (the "Abbott Agreement".) Pursuant to the Agreement, SpectRx has
granted to Abbott a worldwide license under its patents, patent applications
and know how (the "Technology") useful in the Field, including improvements, to
manufacture and sell products in the Field. The license is exclusive in all
countries except Singapore and the Netherlands where the license is
non-exclusive. Abbott also has certain rights of first negotiation with the
Company regarding any rights the Company may have to license the Technology for
the development and commercialization of other products relating to the
measurement of analytes in interstitial fluid and the delivery of therapeutic
agents based on such measurements. Under the Abbott Agreement, SpectRx receives
from Abbott development funding, payments on achievement of milestones and a
royalty on Abbott product sales.


                                     -11-
<PAGE>   12

          In conjunction with the first agreement, Abbott made a $3 million
equity investment in SpectRx in 1996 whereby it purchased 500,000 shares of
Series C Preferred Stock which converted into 357,143 shares of Common Stock
upon the Company's initial public offering. Abbott subsequently purchased
SpectRx Common Stock on the open market and currently owns 6.2% of the
outstanding Stock of the Company. In conjunction with the signing of the
amendment, Abbott made a $5.25 million equity investment whereby it purchased
100,000 shares of Redeemable, Convertible Preferred Stock which is convertible
into the Company Common Stock. The conversion price is to be set at the market
price at the date of conversion, or at $9.388 per share, whichever is higher.
If the stock were to convert at $9.388 per share, Abbott would own 13.2% of the
outstanding stock of the Company, based upon shares outstanding on December 31,
1999.

          Under the Abbott Agreement, the parties agreed to jointly conduct a
research program designed to demonstrate that the Company's single use glucose
monitoring product can extract an adequate sample of interstitial fluid in a
targeted time period. The focus of that development activity through August
1998 was toward a single use product concept. During the joint development
program, which began in the fourth quarter of 1996, Abbott paid mutually agreed
development costs. Abbott currently is responsible for all research on means of
extracting adequate samples of interstitial fluid related to single use glucose
monitoring applications. The current focus of research and development activity
is on the continuous monitoring application. After satisfactory demonstration
of sample extraction and measurement of glucose in interstitial fluid using the
continuous process, and if Abbott wishes to commercialize the product, it is
responsible for further product development and obtaining all required
regulatory approvals. After obtaining these regulatory approvals, Abbott is
required to diligently pursue the sales of the products but is not prohibited
from marketing competing products. If Abbott elects not to commercialize the
product the agreement may be terminated by either party. Abbott has a fixed
period from the date of notice to the Company of its intention to commercialize
the product in which to complete commercialization and begin shipment of
products. If such commercialization has not been completed within the permitted
time, SpectRx may terminate the agreement.

          Under the Abbott Agreement, all technology invented solely by SpectRx
during the joint development program is owned solely by SpectRx. All technology
invented solely by Abbott and all clinical data, regulatory filings and
government marketing approvals developed solely by Abbott are the property of
Abbott. On certain early termination events, SpectRx has a right to obtain a
license to certain of the relevant Abbott technology. Technology jointly
invented during the joint development program will be jointly owned pursuant to
a royalty sharing arrangement.

          The Abbott Agreement remains in effect until the expiration of the
last licensed patent to expire. Abbott has the right to terminate the Abbott
Agreement without cause upon not less than 60 days' prior notice to the Company
at any time prior to the first shipment of products and upon not less than 120
days' prior notice to the Company thereafter. Abbott may terminate the Abbott
Agreement upon not less than 30 days' prior notice to the Company for certain
product development failures.

Welch Allyn

          In December 1998, SpectRx entered into a Development and
Commercialization Agreement with Welch Allyn, Inc. with respect to noninvasive
cervical and skin cancer diagnostic products. Under the terms of the agreement,
the two companies jointly share in the development costs for such products and
also will jointly share in the revenue produced by such products, if those
products are developed to commercialization. SpectRx can also receive certain
milestone payments pursuant to the agreement. The agreement further anticipates
that both Welch Allyn and SpectRx would manufacture portions of any
commercialized products and would collaborate in sales and marketing. Both
SpectRx and Welch Allyn are prohibited from pursuing development of devices,
utilizing the technology covered by the agreement, with another party while the
collaboration remains in effect. The agreement specifically focuses on the
development of a cervical cancer detection product. Should SpectRx determine
through research efforts that an application of the technology for the
detection of skin cancer is feasible, the agreement provides for, and retains
certain rights for Welch Allyn to expand the relationship with SpectRx to
develop and commercialize a skin cancer (melanoma) detection product. In
December 1999, SpectRx completed the requirements for Phase II (feasibility),
which triggered a milestone payment of $700,000.

LICENSING ARRANGEMENTS

Georgia Tech Research Corporation

          The Company has a license agreement with Georgia Tech Research
Corporation ("GTRC") pursuant to which GTRC has granted the Company an
exclusive, worldwide license (including the right to grant sublicenses) to
make, use and sell products that incorporate GTRC's know how related to a
method of using non-invasive instrumentation to quantitatively measure
molecular changes in living human lenses for the purposes of diagnosing
diabetes and precataractous conditions (the "GTRC Agreement"). Under the
license, the Company must pay a royalty to GTRC on net sales of any such
products manufactured and sold by the Company. The term of the GTRC Agreement
is until the expiration date of the last expiring patent covering any of the
technology licensed or, if no patent issues, for 15 years from the date of
execution of the GTRC Agreement.

Altea Technologies, Inc

          In March 1996, SpectRx entered into a License and Joint Development
Agreement (the "Altea/Nimco Agreement") among the Company, Altea ("Altea") and
Non-Invasive Monitoring Company, Inc. ("Nimco") pursuant to which certain
rights in respect of jointly developed technology are allocated between the
Company and Altea. Both Altea and Nimco are jointly controlled by Jonathan
Eppstein, a former Vice President of the Company, and his sister. The
Altea/Nimco Agreement also covers one granted patent and know how related to
the glucose monitoring product, the joint application of the Company and Altea
for a U.S. patent and an international patent related to the glucose monitoring
product, and provides for continued joint development efforts between SpectRx
and Altea as mutually agreed. The Altea/Nimco Agreement further provides for
the joint ownership by SpectRx and Altea of certain patents and technology
relating to the transdermal/intradermal movement of substances utilizing
various methods. Under the Altea/Nimco Agreement, SpectRx receives worldwide,
exclusive rights to any technology for monitoring applications covered by the
Nimco patents and related joint technology and Altea receives exclusive,
worldwide rights to any technology for delivery applications covered by the
joint technology. Future inventions in certain areas made by each of SpectRx
and Altea based on newly developed technology related to the licensed
technology could be included within the Altea/Nimco Agreement.

          SpectRx is obligated to pay royalties to Nimco for products using its
technology and to Altea for products using its technology, in each case based
on net sales of products and net revenues from sublicensees. Royalties on
products using both Nimco and Altea technology will be allocated as mutually
agreed. Minimum annual royalties are payable by SpectRx to Altea. See Note 8 of
Notes to Consolidated Financial Statements. If actual accrued royalties are
less than the minimum royalty amount, SpectRx may pay Altea the difference or
the license will become non-exclusive. Thereafter, SpectRx must offer a right
of first refusal to acquire exclusive rights to the monitoring technology to
Altea.

          The term of the Altea/Nimco Agreement is for the life of the patents
covered by the agreement. The agreement may be terminated by any party in the
event of a default by any other party that is not cured within 90 days of
notice to the defaulting party. The agreement may be terminated globally by
Altea if SpectRx fails to commercialize any product, use or application
utilizing the monitoring technology in any major country by the date of the
first commercial shipment date under the Abbott Agreement and may be terminated
by Altea with respect to certain regions if SpectRx fails to commercialize any
product, use or application in those regions by this date. SpectRx may
terminate the agreement upon not less than three months prior notice to Altea
and Nimco if given before it has commercialized the technology and upon not
less than six months prior notice to each party if given after
commercialization has commenced. Except in the case of termination of the
agreement by SpectRx for breach, upon termination all technology and joint
technology shall become the exclusive property of Altea, except the Nimco
patents. If the agreement is terminated by SpectRx for breach, all rights to
the monitoring technology in the countries in which SpectRx has retained its
exclusive rights shall become the exclusive property of SpectRx, each party
shall retain non-exclusive rights to the monitoring technology in other
countries, and Altea shall retain all rights to the delivery technology. If
SpectRx loses its rights to the monitoring technology for failure to
commercialize (but not due to breach), Altea and Nimco, after their
reacquisition of rights from


                                     -13-
<PAGE>   14

SpectRx, will pay an amount of money by way of a royalty to SpectRx according
to a formula to reflect each party's relative investment.

The University of Texas M.D. Anderson Cancer Center

          In March 1996, SpectRx, entered into a Patent License Agreement with
the Board of Regents (the "Board") of the University of Texas System and M.D.
Anderson pursuant to which the Board granted SpectRx an exclusive license under
certain of its patents to manufacture, have manufactured, use and sell products
within the United States for use within the licensed field of optical
measurement of bilirubin in human tissue (the "MDA Patent License Agreement").
SpectRx has the right to assign this license to affiliates and the right to
sublicense the foregoing rights. In connection with the MDA Patent License
Agreement, SpectRx has agreed to pay all expenses incurred in prosecuting and
maintaining the patents licensed and a royalty on net sales of products that
incorporate the licensed patents, subject to annual minimum royalty payments.
See Note 8 of Notes to Consolidated Financial Statements. The term of the MDA
Patent License Agreement is until the expiration date of the last expiring
patent licensed. The Board has the right at any time after one year from the
effective date of the MDA Patent License Agreement to terminate the license if
SpectRx, within 90 days after written notice from the Board, fails to provide
written evidence satisfactory to the Board that SpectRx has commercialized or
is actively and effectively attempting to commercialize an invention licensed
under the MDA Patent License Agreement.

Joseph Lakowicz, Ph.D.

          The Company has a license agreement with Joseph Lakowicz, Ph.D.
whereby Dr. Lakowicz has granted the Company an exclusive, worldwide license
(including the right to grant sublicenses) to make, use, and sell medical
products that incorporate Dr. Lakowicz's intellectual property related to
lifetime fluorescence technology (the "Lakowicz Agreement"). The intellectual
property consists of a portfolio of granted patents, patent applications and
foreign filings in the area of lifetime fluorescence technology. The Company
has agreed to pay a royalty to Dr. Lakowicz on net sales of such products
manufactured and sold. Additionally, the Company is committed to fund certain
research programs under the direction of Dr. Lakowicz. See Note 8 of Notes to
Consolidated Financial Statements, which includes these funding commitments.
The Company has sublicensed some parts of this intellectual property related to
invasive blood tests to its subsidiary, FluorRx, Inc. The term of the Lakowicz
Agreement is until the expiration date of the last expiring patent covering any
of the technology licensed.


RESEARCH, DEVELOPMENT AND ENGINEERING

          To date, the Company has been engaged primarily in the research,
development and testing of the Company's glucose monitoring, diabetes
detection, infant jaundice and cancer detection products, including research
for and development of its core biophotonic technologies. Since inception to
December 31, 1999, the Company incurred approximately $17.6 million in research
and development expenses, net of approximately $4.6 million which was
reimbursed through collaborative arrangements. Three distinct groups within the
Company conduct research, development and engineering. One group consists of 24
engineers and support personnel who design optics, electronics, mechanical
components and software for the infant jaundice, diabetes detection, continuous
glucose monitoring and non-invasive cervical cancer detection products. A
second group consists of 21 scientists and engineers who devote their time to
the development of microporation technology for the monitoring of glucose and
other analytes. The third group consists of 12 scientists and engineers focused
on the development of cancer detection products.

          The Company believes that the interstitial fluid sampling technology
under development at SpectRx and Abbott for use in connection with the
Company's glucose monitoring products may also be used to develop alternatives
for certain blood tests where the analyte being tested is also present in
comparable volumes in interstitial fluid. Abbott has a right of first
negotiation with the Company regarding the use of interstitial fluid sampling
technology for these applications.

          In 1996, SpectRx executed a licensing agreement with Dr. Lakowicz of
the University of Maryland pursuant to which the Company licenses a portfolio
of intellectual property related to lifetime fluorescence technology, a
technology used to determine the spectroscopic fingerprint of a substance. The
Company believes lifetime fluorescence technology may have applications
including in vitro blood chemistry, molecular diagnostics, flow cytometry,
combinatorial chemistry for pharmaceutical discovery research and noninvasive
optical diagnostics. All activity related to this technology is being conducted
by our subsidiary, FluorRx.

          To date, the Company has only tested prototypes of its glucose
monitoring and cancer products. Because the Company's research and clinical
development programs are at an early stage, substantial additional research and
development and clinical trials will be necessary before commercial prototypes
of the Company's glucose monitoring and cancer detection products are produced.
The company is developing the pre-production prototypes and beginning its
ramp-up for production of the diabetes detection device. While significant
progress has been made in development and engineering, considerable additional
effort and expense will be required before a commercial device is shipped.


MANUFACTURING

          One element of the Company's business strategy is to manufacture
certain of its products and to outsource the production of other, high volume
products and associated disposables. To date, the Company's manufacturing
activities have consisted of building certain prototype devices, developing
production infrastructure and building production versions of its BiliChek(TM)
and BiliCal(TM) products. If the Company successfully develops its diabetes
detection product and, together with Roche Diagnostics obtains FDA clearance
and other regulatory approvals to market this product, the Company will
undertake to manufacture both of these products in commercial quantities. The
Company has little experience manufacturing such products in the volumes that
would be necessary for the Company to achieve significant commercial sales.
Currently 12 individuals are employed by the Company to accomplish the
production planning, quality system management, facility development, and
production scaling that will be needed to bring production to commercial
levels. The Company announced in 1998 that it had received ISO 9001/EN46001 and
CE mark Certification. These approvals enabled the Company to commence
production of its BiliChek(TM) and BiliCal(TM) products and to begin shipment
of these products into markets for which it has received regulatory clearance.


SALES, MARKETING AND DISTRIBUTION

          The Company has elected to focus most of the sales and distribution
of its current and developing products through its collaborative partners. The
Company believes that by aligning with larger, more established partners, in
specific market segments, it can utilize its partners' already developed
strengths and more effectively and quickly penetrate the market place. The
Company's primary efforts to date have been to build the skill and information
base to identify and quantify market segments to which the Company's
technologies can be economically developed and marketed and to launch the
BiliChek(TM) product system.

          The Company has developed the BiliChek(TM) and BiliCal(TM) internal
marketing and distribution program to an introductory stage. SpectRx has
developed packaging, advertising, display materials, and training, and has, in
addition, signed distribution agreements or is in negotiation with companies it
believes to be highly experienced in the neonatal markets that SpectRx is
targeting in Europe, Asia and South America. The Company has also added or
engaged marketing personnel to develop and execute the programs necessary to
launch the BiliChek(TM) system and to manage sales of these products. The
Company launched its products in markets outside the U.S. and Canada in April
1998 and began introductory programs during the remainder of 1998.
Nevertheless, significant volumes of these products have not yet been shipped
and the efficacy of the marketing programs or the distributors has not yet been
tested with SpectRx's products.


                                     -15-
<PAGE>   16


          Respironics has the exclusive right to market and sell the Company's
infant jaundice product in the United States and Canada. Abbott has the
exclusive right to market and sell the Company's glucose monitoring products in
all countries except Singapore and the Netherlands, where the license is
non-exclusive. Roche Diagnostics has the exclusive worldwide right to market
and sell the Company's diabetes detection product. It is anticipated that Welch
Allyn and SpectRx will jointly manage the sales and marketing of any cancer
products that are developed.


PATENTS

         The Company has pursued a strategy of developing and acquiring patents
and patent rights and licensing technology. SpectRx's success depends in large
part upon its ability to establish and maintain the proprietary nature of its
technology through the patent process and to license from others patents and
patent applications necessary to develop its products. The Company has licensed
from Nimco one granted patent and know-how related to its glucose monitoring
product, jointly applied with Altea for a U.S. patent and an international
patent related to this device and has licensed this granted patent and these
patent applications to Abbott pursuant to the parties' collaborative
arrangements. SpectRx has license agreements with GTRC that give the Company the
right to use two patents related to its diabetes detection product, and the
Company has licensed this proprietary technology to Roche Diagnostics pursuant
to the Company's collaborative arrangement. The Company has license agreements
with M.D. Anderson that give SpectRx access to one patent related to the
Company's infant jaundice product, and the Company has applied for two patents
related to this product. SpectRx has licensed the one patent and two patent
applications to Respironics pursuant to its collaborative arrangement with that
company. In addition, SpectRx has licensed from Dr. Joseph Lakowicz of the
University of Maryland several granted patents and patent applications related
to fluorescence spectroscopy that it intends to use in its research and
development efforts.

          There can be no assurance that one or more of the patents held
directly by the Company or licensed by the Company from third parties,
including the disposable components to be used in connection with its glucose
monitoring and infant jaundice products, or processes used in the manufacture
of the Company's products, will not be successfully challenged, invalidated or
circumvented or that the Company will otherwise be able to rely on such patents
for any reason. In addition, there can be no assurance that competitors, many
of whom have substantial resources and have made substantial investments in
competing technologies, will not seek to apply for and obtain patents that
prevent, limit or interfere with the Company's ability to make, use and sell
its products either in the United States or in foreign markets. If any of the
Company's patents are successfully challenged, invalidated or circumvented or
the Company's right or ability to manufacture its products were to be
proscribed or limited, the Company's ability to continue to manufacture and
market its products could be adversely affected, which would likely have a
material adverse effect upon the Company's business, financial condition and
results of operations.


COMPETITION

          The medical device industry in general, and the markets for glucose
monitoring, cervical cancer detection and diabetes detection devices and
processes in particular, are intensely competitive. If successful in its
product development, the Company will compete with other providers of personal
glucose monitors, diabetes detection tests, infant jaundice and cancer
products.

          A number of competitors, including Johnson & Johnson, Inc. (which
owns Lifescan, Inc.), Roche Diagnostics, Bayer AG (which owns Miles
Laboratories, Inc.) and Abbott (which owns MediSense, Inc.) are currently
marketing traditional single use glucose monitors. These monitors are widely
accepted in the health care industry and have a long history of accurate and
effective use. Furthermore, a number of companies have announced that they are
developing products that permit non-invasive and less invasive glucose
monitoring. Accordingly, competition in this area is expected to increase.


                                     -16-
<PAGE>   17

          There is also competition in the diabetes detection and infant
jaundice markets. The existing blood test providers, companies that produce
blood tests and other technologies that could replace blood testing will
compete for a share of these markets.

          Competition in cancer detection is also intense. Current screening
systems, primarily the Pap smear and colposcopy, are well established and
pervasive. The Company will be required, in conjunction with Welch Allyn, to
develop devices that are more accurate, easier to use or less costly to
administer, such that these devices have a competitive advantage to be
commercially successful. In addition to existing external competitors,
SpectRx's partner, Welch Allyn, is currently a competitor in the colposcopy
market.


GOVERNMENT REGULATION

          All of the Company's products are regulated as medical devices.
Medical device products are subject to rigorous FDA and other governmental
agency regulations in the United States and may be subject to regulations of
relevant foreign agencies. The FDA regulates the clinical testing, manufacture,
labeling, packaging, marketing, distribution and record keeping for such
products in order to ensure that medical products distributed in the United
States are safe and effective for their intended uses. Noncompliance with
applicable requirements can result in import detentions, fines, civil
penalties, injunctions, suspensions or losses of regulatory approvals or
clearances, recall or seizure of products, operating restrictions, refusal of
the government to approve product export applications or allow the Company to
enter into supply contracts, and criminal prosecution. Failure to obtain
regulatory approvals, the restriction, suspension or revocation of regulatory
approvals or clearances, if obtained, or any other failure to comply with
regulatory requirements would have a material adverse effect on the Company's
business, financial condition and results of operations.

          The Clinical Chemistry Branch of the FDA's Division of Clinical
Laboratory Devices (the "Branch") has traditionally been the reviewing branch
for blood-based personal glucose monitoring products. The Clinical Chemistry
and Clinical Toxicology Devices Panel (the "Panel") is an external advisory
panel that provides advice to the Branch regarding devices that are reviewed by
the Branch. The panel meets from time to time and provides comments on testing
guidelines. There can be no assurance that the Panel's comments will not result
in a FDA policy or change in FDA policy that is materially adverse to the
Company's regulatory position.

          In the United States, medical devices are classified into one of
three classes (Class I, II or III), on the basis of the controls deemed
necessary by the FDA to reasonably assure their safety and effectiveness. Under
FDA regulations, Class I devices are subject to general controls (for example,
labeling, premarket notification and adherence to GMP), and Class II devices
are subject to general and special controls (for example, performance
standards, postmarket surveillance, patient registries, and FDA guidelines).
Generally, Class III devices are those which must receive premarket approval
from the FDA to ensure their safety and effectiveness (for example,
life-sustaining, life-supporting and implantable devices, or new devices which
have not been found substantially equivalent to legally marketed Class I or II
devices).

          A medical device manufacturer may seek clearance to market a medical
device by filing a 510(k) premarket notification with the FDA if a medical
device manufacturer establishes that a newly developed device is "substantially
equivalent" to either a device that was legally marketed prior to May 28, 1976,
the date upon which the Medical Device Amendments of 1976 were enacted, or to a
device that is currently legally marketed and has received 510(k) premarket
clearance from the FDA. The 510(k) premarket notification must be supported by
appropriate information, including, where appropriate, data from clinical
trials, establishing the claim of substantial equivalence to the satisfaction
of the FDA. Commercial distribution of a device for which a 510(k) premarket
notification is required can begin only after the FDA issues an order finding
the device to be "substantially equivalent" to a predicate device. The FDA has
recently been requiring a more rigorous demonstration of substantial
equivalence than in the past. It generally takes from four to 12 months from
the date of submission to obtain clearance of a 510(k) submission, but it may
take substantially longer. The FDA may determine that a proposed device is not
substantially equivalent to a legally marketed device, or that additional
information is needed before a substantial equivalence determination can be
made.


                                     -17-
<PAGE>   18

          A "not substantially equivalent" determination, or a request for
additional information, could delay the market introduction of new products
that fall into this category and could have a material adverse effect on the
Company's business, financial condition and results of operations. For any of
the Company's products that are cleared through the 510(k) process,
modifications or enhancements that could significantly affect the safety or
efficacy of the device or that constitute a major change to the intended use of
the device will require new 510(k) submissions or approval of a PMA
application. Any modified device for which a new 510(k) premarket notification
is required cannot be distributed until 510(k) clearance is obtained for the
modified device. There can be no assurance that the Company will obtain 510(k)
clearance in a timely manner, if at all, for any devices or modifications to
devices for which it may submit a 510(k) notification.

          A PMA application must be submitted if a proposed device is not
substantially equivalent to a legally marketed Class I or Class II device, or
for a Class III device for which FDA has called for PMAs. The PMA application
must contain valid scientific evidence to support the safety and effectiveness
of the device which includes the results of clinical trials, all relevant bench
tests, and laboratory and animal studies. The PMA application must also contain
a complete description of the device and its components, and a detailed
description of the methods, facilities and controls used for manufacture,
including, where appropriate, the method of sterilization and its assurance. In
addition, the submission must include proposed labeling, advertising literature
and training methods (if required). If human clinical trials of a device are
required in connection with a PMA application, and the device presents a
"significant risk," the sponsor of the trial (usually the manufacturer or the
distributor of the device) is required to file an investigational device
exemption ("IDE") application prior to commencing human clinical trials. The
IDE application must be supported by data, typically including the results of
animal and laboratory testing, and a description of how the device will be
manufactured. If the IDE application is reviewed and approved by the FDA and
one or more appropriate institutional review boards ("IRBs"), human clinical
trials may begin at a specific number of investigational sites with a specific
number of patients, as approved by the FDA. If the device presents a
"nonsignificant risk" to the patient, a sponsor may begin clinical trials after
obtaining approval for the study by one or more appropriate IRBs, but FDA
approval for the commencement of the study is not required. Sponsors of
clinical trials are permitted to sell those devices distributed in the course
of the study provided such compensation does not exceed recovery of costs of
manufacture, research, development and handling. An IDE supplement must be
submitted to and approved by FDA before a sponsor or an investigator may make a
significant change to the investigational plan that may affect the plan's
scientific soundness or the rights, safety or welfare of human subjects.

          Upon receipt of a PMA application, the FDA makes a threshold
determination as to whether the application is sufficiently complete to permit
a substantive review. If the FDA determines that the PMA application is
sufficiently complete to permit a substantive review, the FDA will accept the
application for filing. An incomplete application will be returned to the
sponsor and must be resubmitted and accepted for filing before the application
will be substantively reviewed. Once the submission is accepted for filing, the
FDA begins an in-depth review of the PMA application. An FDA review of a PMA
application generally takes one to two years from the date the PMA application
is accepted for filing, but may take significantly longer. The review time is
often significantly extended by the FDA asking for more information or
clarification of information already provided in the submission. During the PMA
application review period, the submission may be sent to an FDA-selected
scientific advisory panel composed of physicians and scientists with expertise
in the particular field. The FDA scientific advisory panel issues a
recommendation to the FDA that may include conditions for approval. The FDA is
not bound by the recommendations of the advisory panel. Toward the end of the
PMA application review process, the FDA will conduct an inspection of the
manufacturer's facilities to ensure that the facilities are in compliance with
applicable GMP requirements.

          If the FDA evaluations of both the PMA application and the
manufacturing facilities are favorable, the FDA will issue an approvable
letter, which usually contains a number of conditions which must be met in
order to secure final approval of the PMA application. When those conditions
have been fulfilled to the satisfaction of the FDA, the agency will issue a PMA
application approval letter authorizing commercial marketing of the device for
certain indications and intended uses. The PMA application review process can
be expensive, uncertain and lengthy. A number of devices for which a PMA has
been sought have never been approved for marketing. The FDA may also determine
that additional clinical trials are necessary, in which case the PMA may be
significantly delayed while such trials are conducted and


                                     -18-

data is submitted in an amendment to the PMA application. Modifications to the
design, labeling or manufacturing process of a device that is the subject of an
approved PMA application, its labeling, or manufacturing process may require
approval by the FDA of PMA supplements or new PMA applications. Supplements to
a PMA often require the submission of the same type of information required for
an initial PMA, except that the supplement is generally limited to that
information needed to support the proposed change from the product covered by
the original PMA. The FDA generally does not call for an advisory panel review
for PMA supplements. There can be no assurance that, if required, the Company
will be able to meet the FDA's PMA requirements or that any necessary approvals
will be received. Failure to comply with regulatory requirements would have a
material adverse effect on the Company's business, financial condition and
results of operations.

          Regulatory approvals and clearances, if granted, may include
significant labeling limitations and limitations on the indicated uses for
which the product may be marketed. In addition, to obtain such approvals and
clearances, the FDA and certain foreign regulatory authorities impose numerous
other requirements with which medical device manufacturers must comply. FDA
enforcement policy strictly prohibits the marketing of approved medical devices
for unapproved uses. Any products manufactured or distributed by the Company
pursuant to FDA clearances or approvals are subject to pervasive and continuing
regulation by the FDA. The FDA also requires the Company to provide it with
information on death and serious injuries alleged to have been associated with
the use of the Company's products, as well as any malfunctions that would
likely cause or contribute to death or serious injury. Failure to comply with
applicable regulatory requirements can result in, among other things, warning
letters, fines, injunctions, civil penalties, recall or seizure of products,
total or partial suspension of production, refusal by the government to grant
premarket clearance or premarket approval for devices, withdrawals of approvals
and criminal prosecutions.

          The Company is required to register with the FDA as a device
manufacturer and list its products with the Agency. The Company also is subject
to biannual inspections, for compliance with GMP, by the FDA and state agencies
acting under contract with the FDA. The GMP regulations require that the
Company manufacture its products and maintain its documents in a prescribed
manner with respect to manufacturing, testing, quality assurance and quality
control activities. The FDA also has promulgated final regulatory changes to
the GMP regulations that require, among other things, design controls and
maintenance of service records, and which will increase the cost of complying
with GMP requirements.

          Labeling and promotional activities are subject to scrutiny by the
FDA and in certain instances, by the Federal Trade Commission. The FDA actively
enforces regulations prohibiting marketing of products for unapproved users.
The Company and its products are also subject to a variety of state and local
laws and regulations in those states and localities where its products are or
will be marketed. Any applicable state or local regulations may hinder the
Company's ability to market its products in those states or localities.
Manufacturers are also subject to numerous federal, state and local laws
relating to such matters as safe working conditions, manufacturing practices,
environmental protection, fire hazard control and disposal of hazardous or
potentially hazardous substances. There can be no assurance that the Company
will not be required to incur significant costs to comply with such laws and
regulations now or in the future or that such laws or regulations will not have
a material adverse effect upon the Company's ability to do business.

          International sales of the Company's products are subject to the
regulatory requirements of each target country. The regulatory review process
varies from country to country. The ISO 9000 series of standards for quality
operations have been developed to ensure that companies know the standards of
quality to which they must adhere to receive certification. The European Union
has promulgated rules which require that medical products received by mid-1998
the right to affix the CE mark, an international symbol of adherence to quality
assurance standards and compliance with applicable European medical device
directives. The ISO 9001 certification was one of the CE mark certification
requirements required by mid-1998. The Company currently has ISO 9001/EN46001
certification. Failure, however, to maintain the right to affix the CE mark
would prohibit the Company from selling its products in member countries of the
European Union.


                                     -19-
<PAGE>   20



          The Company will rely upon its corporate partners to obtain certain
United States and foreign regulatory approvals and if such approvals are
obtained the Company will rely upon its corporate partners to remain in
compliance with ongoing United States and foreign regulatory restrictions. The
inability or failure of such third parties to comply with the varying
regulations or the imposition of new regulations would materially adversely
affect the Company's business, financial condition and results of operations.


EMPLOYEES AND CONSULTANTS

          As of December 31, 1999, the Company had 62 employees and consulting
or other contract arrangements with 41 additional persons to provide services
to the Company on a full- or part-time basis. Of the 103 people so employed or
engaged by the Company, 59 are engaged in research and development activities,
10 are engaged in sales and marketing activities, 7 are engaged in regulatory
affairs and quality assurance, 13 are engaged in manufacturing and development,
and 14 are engaged in administration and accounting. No employees are covered
by collective bargaining agreements, and the Company believes it maintains good
relations with its employees.

          The Company's ability to operate successfully and manage its
potential future growth depends in significant part upon the continued service
of certain key scientific, technical, managerial and finance personnel, and its
ability to attract and retain additional highly qualified scientific,
technical, managerial and finance personnel. None of these key employees has an
employment contract with the Company nor are any of these employees covered by
key person or similar insurance. In addition, if the Company, together with its
collaborative partners, is able to successfully develop and commercialize the
Company's products, the Company will need to hire additional scientific,
technical, marketing, managerial and finance personnel. The Company faces
intense competition for qualified personnel in these areas, many of whom are
often subject to competing employment offers, and there can be no assurance
that the Company will be able to attract and retain such personnel. The loss of
key personnel or inability to hire and retain additional qualified personnel in
the future could have a material adverse effect on the Company's business,
financial condition and results of operations.


RISK FACTORS

          The following risk factors should be considered carefully in addition
to the other information presented in this report. This report contains forward
looking statements that involve risks and uncertainties. The Company's actual
results may differ significantly from the results discussed in the forward
looking statements. Factors that might cause such differences include, but are
not limited to, the following risk factors.

Early Stage of Development; No Assurance of Successful Product Development

          To date, the Company has released for sale one product line. For the
remainder of its expected products, the company has only tested prototypes and
pre-release production versions of its products. Because the Company's research
and clinical development programs are at an early stage, substantial additional
research and development and clinical trials will be necessary before
commercial prototypes of the Company's other products are produced. The Company
could encounter unforeseen problems in the development of those products such
as delays in conducting clinical trials, delays in the supply of key components
or delays in overcoming technical hurdles. There can be no assurance that the
Company will be able to successfully address the problems that may arise during
the development and commercialization process. In addition, there can be no
assurance that all of the Company's products will be successfully developed,
proven safe and efficacious in clinical trials, meet applicable regulatory
standards, be capable of being produced in commercial quantities at acceptable
costs, be eligible for third-party reimbursement from governmental or private
insurers, be successfully marketed or achieve market acceptance. If any of the
Company's development programs are not successfully completed, required
regulatory approvals or clearances are not obtained, or products for which
approvals or clearances are obtained are not commercially successful, the
Company's business, financial condition and results of operations would be
materially adversely affected.


                                     -20-
<PAGE>   21

          The Company's business is subject to the risks inherent in the
development of new products using new technologies and approaches. There can be
no assurance that unforeseen problems will not develop with these technologies
or applications, that the Company will be able to successfully address
technological challenges it encounters in its research and development programs
or that commercially feasible products will ultimately be developed by the
Company.

Dependence on Collaborative Arrangements

          The Company's business strategy for the development, clinical
testing, regulatory approval, manufacturing and commercialization of its
products depends upon the Company's ability to selectively enter into and
maintain collaborative arrangements with leading medical device companies. The
Company has entered into collaborative arrangements with, (i) Respironics under
which Respironics has significant responsibility for undertaking or funding the
development, clinical testing, regulatory approval process and sale of the
Company's infant jaundice product in the United States and Canada, (ii) Roche
Diagnostics under which Roche Diagnostics has significant responsibility for
undertaking or funding the development, clinical testing, regulatory approval
process and sale of the Company's diabetes detection product, (iii) Abbott
under which Abbott is primarily responsible for undertaking or funding the
development, clinical testing, regulatory approval process, manufacture and
sale of the Company's glucose monitoring products and (iv) Welch Allyn which is
a cooperative development program in the early stages of product development
for a cervical cancer detection product. The agreements evidencing these
collaborative arrangements grant a substantial amount of discretion to each of
Abbott, Roche Diagnostics, Respironics and Welch Allyn. For example, each of
these collaborative partners may terminate their respective collaborative
arrangements with the Company effective upon the expiration of certain notice
periods. In addition, the obligation of each of the Company's collaborative
partners to fund or undertake the development, clinical testing, regulatory
approval process, marketing, distribution and/or sale of the products covered
by their respective collaborative arrangements with the Company is, to a large
extent, dependent upon the satisfaction of certain goals or "milestones" by
certain specified dates, some of which are outside the Company's control. To
the extent that the obligations of the Company's collaborative partners to fund
or undertake all or certain of the foregoing activities are not contingent upon
the satisfaction of certain goals or milestones, the collaborative partners
nevertheless retain a significant degree of discretion regarding the timing of
these activities and the amount and quality of financial, personnel and other
resources that they devote to these activities. Furthermore, there can be no
assurance that disputes will not arise between the Company and one or more of
its collaborative partners regarding their respective rights and obligations
under the collaborative arrangements. Finally, there can be no assurance that
one or more of the Company's collaborative partners will not be able, due to
financial, regulatory or other reasons, to satisfy its obligations under its
collaborative arrangement with the Company or will not intentionally or
unintentionally breach its obligations under the arrangement.

          There can be no assurance that one or more of the Company's
collaborative partners will not, for competitive reasons, support, directly or
indirectly, a company or product that competes with the Company's product that
is the subject of its collaborative arrangement with the Company. Furthermore,
any dispute between the Company and one of its collaborative partners might
require the Company to initiate or defend expensive litigation or arbitration
proceedings.

          Any termination of any collaborative arrangement by one of the
Company's collaborative partners, any inability of a collaborative partner to
fund or otherwise satisfy its obligations under its collaborative arrangements
with the Company and any significant dispute with, or breach of a contractual
commitment by, a collaborative partner, would likely require the Company to
seek and reach agreement with another collaborative partner or to assume, to
the extent possible and at its own expense, all the responsibilities being
undertaken by this collaborative partner. There can be no assurance that the
Company would be able to reach agreement with a replacement collaborative
partner. If the Company were not able to find a replacement collaborative
partner, there can be no assurance that the Company would be able to perform or
fund the activities for which such collaborative partner is currently
responsible. Even if the Company were able to perform and fund these
activities, the Company's capital requirements would increase substantially. In
addition, the further development and the clinical testing, regulatory approval
process, marketing, distribution and sale of the product covered by such
collaborative arrangement would be significantly delayed.


                                     -21-
<PAGE>   22

          Any of the foregoing circumstances could have a material adverse
effect upon the Company's business, financial condition and results of
operations.

Limited Operating History; History of Losses and Expectations of Future Losses

          The Company has a limited operating history upon which its prospects
can be evaluated. Such prospects must be considered in light of the substantial
risks, expenses and difficulties encountered by entrants into the medical
device industry, which is characterized by an increasing number of
participants, intense competition and a high failure rate. The Company has
experienced operating losses since its inception, and, as of December 31, 1999,
the Company had an accumulated deficit of approximately $25.3 million. To date,
the Company has engaged primarily in research and development efforts. The
Company has only generated limited revenues from product sales and does not
have significant experience in manufacturing, marketing or selling its
products. There can be no assurance that the Company's development efforts will
result in commercially viable products, that the Company will be successful in
introducing its products, or that required regulatory clearances or approvals
will be obtained in a timely manner, or at all. There can be no assurance that
the Company's products will ever gain market acceptance or that the Company
will ever generate significant revenues or achieve profitability. The
development and commercialization of its products will require substantial
development, regulatory, sales and marketing, manufacturing and other
expenditures. The Company expects its operating losses to continue through 2001
as it continues to expend substantial resources to complete development of its
products, obtain regulatory clearances or approvals, build its marketing,
sales, manufacturing and finance organizations and conduct further research and
development.

Government Regulations; No Assurance of Regulatory Approvals

          The design, manufacturing, labeling, distribution and marketing of
the Company's products will be subject to extensive and rigorous government
regulation in the United States and certain other countries where the process
of obtaining and maintaining required regulatory clearance or approvals is
lengthy, expensive and uncertain. In order for the Company to market its
products in the United States, the Company must obtain clearance or approval
from the FDA. The Company intends to seek clearance to market each of its
products, where possible through a 510(k) premarket notification supported by
clinical data. A 510(k) premarket notification has been filed with and approved
by the FDA, for clearance to market the Company's infant jaundice product. A
510(k) has been filed for expanded use during phototherapy treatment for the
BiliChek(TM). A 510(k) premarket notification was filed in 1998 with the FDA
for clearance to market the diabetes detection product. The 510(k) was later
withdrawn, and discussions have been held by Roche Diagnostics with the FDA in
preparation for clinical activity and the submission of a PMA for this product
to be filed in 2000. The Company has not filed any other 510(k) premarket
notification or PMA for clearance with the FDA. A 510k or PMA for the glucose
monitoring product is expected after the completion of development. There can
be no assurance that any such notifications will be filed in accordance with
this schedule, that the FDA will act favorably or quickly on such 510(k)
submissions, or that significant difficulties and costs will not be encountered
during efforts to obtain FDA clearance or approval. Specifically, the FDA may
request additional data or require additional clinical studies be conducted to
obtain 510(k) clearance for one or more of the Company's products. In addition,
there can be no assurance that the FDA will not require the submission of a
premarket approval ("PMA") application to obtain FDA approval to market one or
more of the Company's products. Preliminary expectations regarding the
Company's cancer program and glucose program are that those filings would be a
PMA. The PMA process is more rigorous and lengthier than the 510(k) clearance
process and can take several years from initial filing and require the
submission of extensive supporting data and clinical information. In addition,
there can be no assurance that the FDA will not impose strict labeling or other
requirements as a condition of its 510(k) clearance or PMA, any of which could
limit the Company's ability to market its products. Further, if the Company
wishes to modify a product after FDA clearance of a 510(k) premarket
notification or approval of a PMA application, including changes in indications
or other modifications that could affect safety and efficacy, additional
clearances or approvals will be required from the FDA. Any request by the FDA
for additional data or any requirement by the FDA that the Company conduct
additional clinical studies or submit to the more rigorous and lengthier PMA
process could result in a significant delay in bringing the Company's products
to market and substantial additional research and other expenditures by the
Company. Similarly, any labeling or other conditions or restrictions imposed by
the FDA on the marketing of the Company's products could hinder the Company's
ability to effectively market its products. Any of the foregoing actions by the
FDA could delay or prevent altogether the


                                     -22-

Company's ability to market and distribute its products and could have a
material adverse effect on the Company's business, financial condition and
results of operations.

          In order for the Company to market its products under development in
Europe and certain other foreign jurisdictions, the Company and its
distributors and agents must obtain required regulatory registrations or
approvals and otherwise comply with extensive regulations regarding safety,
efficacy and quality in those jurisdictions. Specifically, certain foreign
regulatory bodies have adopted various regulations governing product standards,
packaging requirements, labeling requirements, import restrictions, tariff
regulations, duties and tax requirements. These regulations vary from country
to country. In order to commence sales in Europe, the Company has obtained ISO
9001 certification and CE mark certification, which is an international symbol
of quality and compliance with applicable European medical device directives.
While the Company has received ISO 9001 and CE mark certification, it must
maintain its certifications in future periods. Failure to receive or maintain
ISO 9001 or CE mark certification or other foreign regulatory approvals could
have a material adverse effect on the Company's business, financial condition
and results of operations. There can be no assurance that the Company will
obtain any other required regulatory registrations or approvals in such
countries or that it will not be required to incur significant costs in
obtaining or maintaining such regulatory registrations or approvals. Delays in
obtaining any registrations or approvals required to market the Company's
products, failure to receive these registrations or approvals, or future loss
of previously obtained registrations or approvals could have a material adverse
effect on the Company's business, financial condition and results of
operations.

          The Company and its collaborative partners will be required to adhere
to applicable FDA regulations regarding Good Manufacturing Practice ("GMP") and
similar regulations in other countries, which include testing, control, and
documentation requirements. Ongoing compliance with GMP and other applicable
regulatory requirements will be strictly enforced in the United States through
periodic inspections by state and federal agencies, including the FDA, and in
foreign jurisdictions by comparable agencies. Failure to comply with applicable
regulatory requirements could result in, among other things, warning letters,
fines, injunctions, civil penalties, recall or seizure of products, total or
partial suspension of production, refusal of the government to grant premarket
clearance or premarket approval for devices, withdrawal of approvals previously
obtained and criminal prosecution. The restriction, suspension or revocation of
regulatory approvals or any other failure to comply with regulatory
requirements would have a material adverse effect on the Company's business,
financial condition and results of operations.

          The Clinical Chemistry Branch of the FDA's Division of Clinical
Laboratory Devices (the "Branch") has traditionally been the reviewing branch
for blood-based personal glucose monitoring products. The Clinical Chemistry
and Clinical Toxicology Devices Panel (the "Panel") is an external advisory
panel that provides advice to the Branch regarding devices that are reviewed by
the Branch. The panel meets from time to time and provides comments to the
Branch regarding guidelines. There can be no assurance that the Panel's
comments will not result in a FDA policy or change in FDA policy that is
materially adverse to the Company's regulatory position.

          The Company will rely upon Abbott, Roche Diagnostics and Respironics
to obtain United States and foreign regulatory approvals and clearances for its
glucose monitoring, diabetes detection and infant jaundice products,
respectively, and if such approvals or clearances are obtained the Company will
rely upon these collaborative partners to maintain them in full force and
effect and to otherwise remain in compliance with all applicable United States
and foreign regulatory restrictions. The inability or failure of such third
parties to comply with the varying regulations or the imposition of new
regulations would materially adversely affect the Company's business, financial
condition and results of operations.

Dependence on Licensed Patent Applications and Proprietary Technology

          SpectRx's success depends in large part upon its ability to establish
and maintain the proprietary nature of its technology through the patent
process and to license from others patents and patent applications necessary to
develop its products. The Company has licensed from Non-Invasive Monitoring
Company, Inc. ("Nimco") one granted patent and know-how related to its glucose
monitoring product, jointly applied with Altea Technologies, Inc. ("Altea") for
a U.S. patent and an international patent related to this device and has
licensed this granted patent and these patent applications


                                     -23-
<PAGE>   24

to Abbott pursuant to the parties' collaborative arrangements. SpectRx has
license agreements with Georgia Tech Research Corporation ("GTRC") that give
the Company the right to use two patents related to its diabetes detection
product, and the Company has licensed this proprietary technology to Roche
Diagnostics pursuant to the Company's collaborative arrangement with Boehringer
Mannheim. The Company has license agreements with the University of Texas M.D.
Anderson Cancer Center ("M.D. Anderson") that give SpectRx access to one patent
related to the Company's infant jaundice product, and the Company has applied
for two patents related to this product. SpectRx has licensed the one patent
and two patent applications to Respironics pursuant to its collaborative
arrangement with that company. In addition, SpectRx has licensed from Joseph
Lakowicz, Ph.D. of the University of Maryland several granted patents and
patent applications related to fluorescence spectroscopy that it intends to use
in its research and development efforts.

          There can be no assurance that one or more of the patents held
directly by the Company or licensed by the Company from third parties,
including the disposable components to be used in connection with its glucose
monitoring and infant jaundice products, or processes used in the manufacture
of the Company's products, will not be successfully challenged, invalidated or
circumvented or that the Company will otherwise be able to rely on such patents
for any reason. In addition, there can be no assurance that competitors, many
of whom have substantial resources and have made substantial investments in
competing technologies, will not seek to apply for and obtain patents that
prevent, limit or interfere with the Company's ability to make, use and sell
its products either in the United States or in foreign markets. If any of the
Company's patents are successfully challenged, invalidated or circumvented or
the Company's right or ability to manufacture its products were to be
proscribed or limited, the Company's ability to continue to manufacture and
market its products could be adversely affected, which would likely have a
material adverse effect upon the Company's business, financial condition and
results of operations.

          The medical device industry has been characterized by extensive
litigation regarding patents and other intellectual property rights. Certain
companies in the medical device industry have instituted intellectual property
litigation, including patent infringement actions, for legitimate and, in
certain cases, competitive reasons. In addition, the United States Patent and
Trademark Office ("USPTO") may institute litigation or interference
proceedings. There can be no assurance that the Company will not become subject
to patent infringement claims or litigation or interference proceedings
instituted by the USPTO to determine the priority of inventions. The defense
and prosecution of intellectual property suits, USPTO interference proceedings
and related legal and administrative proceedings are both costly and time
consuming. Litigation may be necessary to enforce patents issued to the
Company, to protect trade secrets or know-how owned by the Company or to
determine the enforceability, scope and validity of the proprietary rights of
others. Any litigation or interference proceedings brought against, initiated
by or otherwise involving the Company may require the Company to incur
substantial legal and other fees and expenses and may require some of the
Company's employees to devote all or a substantial portion of their time to the
prosecution or defense of such litigation or proceedings. An adverse
determination in litigation or interference proceedings to which the Company
may become a party, including any litigation that may arise against the
Company, could subject the Company to significant liabilities to third parties,
require the Company to seek licenses from third parties or prevent the Company
from selling its products in certain markets, or at all. Although patent and
intellectual property disputes regarding medical devices are often settled
through licensing or similar arrangements, there can be no assurance that the
Company would be able to reach a satisfactory settlement of such a dispute that
would allow it to license necessary patents or other intellectual property.
Even if such a settlement were reached, the settlement process may be expensive
and time consuming and the terms of the settlement may require the Company to
pay substantial royalties. An adverse determination in a judicial or
administrative proceeding or the failure to obtain a necessary license could
prevent the Company from manufacturing and selling its products, which would
have a material adverse effect on the Company's business, financial condition
and results of operations.

          In addition to patents, the Company relies on trade secrets and
proprietary know-how, which it seeks to protect, in part, through
confidentiality and proprietary information agreements. There can be no
assurance that such confidentiality or proprietary information agreements will
not be breached, that the Company would have adequate remedies for any breach,
or that the Company's trade secrets will not otherwise become known to or be
independently developed by competitors.


                                     -24-
<PAGE>   25

Royalty Rates and Manufacturing Profits

          The majority of the Company's revenues and profits are expected to be
derived from royalties and manufacturing profits that the Company will receive
from Abbott, Roche Diagnostics and Respironics resulting from sales of its
glucose monitoring, diabetes detection and infant jaundice products,
respectively. The royalties and manufacturing profits that the Company is
expected to receive from each of its collaborative partners depend on sales of
such products. There can be no assurance that the Company, together with its
collaborative partners, will be able to sell sufficient volumes of the
Company's products to generate substantial royalties and manufacturing profits
for the Company. In addition, the Company's profit margins on some of its
products are not likely to increase over time because the royalty rates and
manufacturing profit rates on those products are predetermined.

          In addition, it is common practice in the glucose monitoring device
industry for manufacturers to sell their glucose monitoring devices at
substantial discounts to their list prices or to offer customers rebates on
sales of their products. Manufacturers offer such discounts or rebates to
expand the use of their products and thus increase the market for the
disposable assay strips they sell for use with their products. Because Abbott
may, pursuant to its collaborative arrangement with the Company, determine the
prices at which it sells the Company's glucose monitoring devices, it may
choose to adopt this marketing strategy. If Abbott adopts this marketing
strategy and discounts the prices at which it sells the Company's glucose
monitoring devices, the royalties earned by the Company in respect of such
sales will be less. There can be no assurance that, if this strategy is
adopted, royalties earned by the Company on sales of the disposable cartridges
to be used in connection with its glucose monitoring device will be equal to or
greater than the royalties the Company would have earned had its glucose
monitoring devices not been sold at a discount. This possible reduction in
royalties on sales of the Company's glucose monitoring devices could have a
material adverse effect upon the Company's business, financial condition and
results of operations.

          The collaboration with Welch Allyn is a joint development and
commercialization effort. It is anticipated that both SpectRx and Welch Allyn
would manufacture portions of the cancer detection device and both would share
in the revenues of products sold to customers. There can be no assurance,
however, that the Company, together with Welch Allyn, will sell sufficient
volumes of these products to generate substantial revenues.

Uncertainty of Market Acceptance

         The Company's products are based upon new methods of glucose
monitoring, diabetes detection, infant jaundice monitoring and cervical cancer
detection. There can be no assurance that any of these products will gain market
acceptance. Physicians and individuals will not recommend or use the Company's
products unless they determine, based on experience, clinical data, relative
cost, and other factors, that these products are an attractive alternative to
current blood-based or other tests that have a long history of safe and
effective use. To date, the Company's products have been utilized by only a
limited number of subjects, and no independent studies regarding the Company's
products have been published. The lack of any such independent studies may have
an adverse effect on the Company's ability to successfully market its products.
In addition, purchase decisions for products like the Company's diabetes
detection and infant jaundice products are greatly influenced by health care
administrators who are subject to increasing pressures to reduce costs. Failure
of the Company's products to achieve significant market acceptance would have a
material adverse effect on the Company's business, financial condition and
results of operations.

Intense Competition

          The medical device industry in general, and the markets in which the
company expects to offer products in particular, are intensely competitive. If
successful in its product development, the Company will compete with other
providers of personal glucose monitors, diabetes detection tests, infant
jaundice and cancer detection products.

          A number of competitors, including Johnson & Johnson, Inc. (which
owns Lifescan, Inc.), Roche Diagnostics, Bayer AG (which owns Miles
Laboratories, Inc.) and Abbott (which owns MediSense, Inc.), are currently
marketing traditional glucose monitors. These monitors are widely accepted in
the health care industry and have a long history of


                                     -25-
<PAGE>   26

accurate and effective use. Furthermore, a number of companies have announced
that they are developing products that permit non-invasive and less invasive
glucose monitoring. Accordingly, competition in this area is expected to
increase.

          Many of the Company's competitors have substantially greater
financial, research, technical, manufacturing, marketing and distribution
resources than the Company and have greater name recognition and lengthier
operating histories in the health care industry. There can be no assurance that
the Company will be able to effectively compete against these and other
competitors. In addition, there can be no assurance that the Company's glucose
monitoring, diabetes detection, infant jaundice or cancer detection products
will replace any currently used devices or systems, which have long histories
of safe and effective use. Furthermore, there can be no assurance that the
Company's competitors will not succeed in developing, either before or after
the development and commercialization of the Company's products, devices and
technologies that permit more efficient, less expensive non-invasive and less
invasive glucose monitoring, diabetes detection, infant jaundice monitoring and
cancer detection. It is also possible that one or more pharmaceutical or other
health care companies will develop therapeutic drugs, treatments or other
products that will substantially reduce the prevalence of diabetes or infant
jaundice or otherwise render the Company's products obsolete. Such competition
could have a material adverse effect on the Company's business, financial
condition and results of operation.

          In addition, there can be no assurance that one or more of the
Company's collaborative partners will not, for competitive reasons, reduce its
support of its collaborative arrangement with the Company or support, directly
or indirectly, a company or product that competes with the Company's product
that is the subject of the collaborative arrangement.

Little Manufacturing Experience; Dependence on Sole Sources of Supply

          To date, the Company's manufacturing activities have only included
its BiliChek(TM) and BiliCal(TM) products on a limited scale. If the Company
successfully develops its diabetes detection product and, together with Roche
Diagnostics obtains FDA clearance and other regulatory approvals to market that
product, the Company will undertake to manufacture this product in significant
volumes. The Company has no experience manufacturing such products in the
volumes that would be necessary for the Company to achieve significant
commercial sales. There can be no assurance that the Company will be able to
establish and maintain reliable, full scale manufacturing of these products at
commercially reasonable costs. Although the Company has leased space that it
plans to use to manufacture its products, it may encounter various problems in
establishing and maintaining its manufacturing operations, resulting in
inefficiencies and delays. Specifically, companies often encounter difficulties
in scaling up production, including problems involving production yield,
quality control and assurance, and shortages of qualified personnel. In
addition, the Company's manufacturing facilities will be subject to GMP
regulations, including possible preapproval inspection, international quality
standards and other regulatory requirements. Difficulties encountered by the
Company in manufacturing scale-up or failure by the Company to implement and
maintain its manufacturing facilities in accordance with GMP regulations,
international quality standards or other regulatory requirements could result
in a delay or termination of production, which could have a material adverse
effect on the Company's business, financial condition and results of
operations.

          The microspectrometer and disposable calibration element, components
of the Company's infant jaundice product, and the blue light module and
calibration element, components of the Company's diabetes detection product,
are each available from only one supplier and these products would require a
major redesign in order to incorporate a substitute component. Certain other
components of the infant jaundice and diabetes detection products are currently
obtained from only one supplier, but have readily available substitute
components that can be incorporated in the applicable product with minimal
design modifications. For the Company's products which require a PMA, the
inclusion of substitute components could require the Company to qualify the new
supplier with the appropriate government regulatory authorities. Alternatively,
for the Company's products which qualify for a 510(k) premarket notification,
the substitute components need only meet the Company's product specifications.
Any significant problem experienced by one of the Company's sole source
suppliers may result in a delay or interruption in the supply of components to
the Company until such supplier cures the problem or an alternative source of
the component is located and qualified. Any delay or interruption would likely
lead to a delay or interruption in the Company's manufacturing operations,
which could have a material adverse effect upon the Company's business,
financial condition and results of operations.

<PAGE>   27

Limited Marketing and Sales Experience

           The Company is responsible for marketing its infant jaundice product
in countries other than the United Sates and Canada. The Company has relatively
limited experience in marketing or selling medical device products and only has
a six person marketing and sales staff. In order to successfully continue to
market and sell its infant jaundice product outside the United States and
Canada, the Company must either develop a marketing and sales force or expand
its arrangements with third parties to market and sell this product. While the
Company has signed distributor agreements for its BiliCheck(TM) and BiliCal(TM)
products, there can be no assurance that the Company will be able to
successfully fully develop a marketing and sales force or that it will be able
to enter into and maintain marketing and sales agreements with third parties on
acceptable terms. If the Company develops its own marketing and sales
capabilities, it will compete with other companies that have experienced and
well-funded marketing and sales operations. If the Company enters into a
marketing arrangement with a third party for the marketing and sale of its
infant jaundice product outside the United States and Canada, any revenues to
be received by the Company from this product will be dependent on this third
party, and the Company will likely be required to pay a sales commission or
similar amount to this party. Furthermore, the Company is currently dependent
on the efforts of Abbott and Roche Diagnostics for any revenues to be received
from its glucose monitoring and diabetes detection products, respectively.
There can be no assurance that the efforts of these third parties for the
marketing and sale of the Company's products will be successful.

Product Liability Risk; Limited Insurance Coverage

          The development, manufacture and sale of medical products entail
significant risks of product liability claims. The Company currently has no
product liability insurance coverage beyond that provided by its general
liability insurance. Accordingly, there can be no assurance that the Company is
adequately protected from any liabilities, including any adverse judgments or
settlements, it might incur in connection with the development, clinical
testing, manufacture and sale of its products. In addition, product liability
insurance is expensive and may not be available to the Company on acceptable
terms, if at all. A successful product liability claim or series of claims
brought against the Company that results in an adverse judgment against or
settlement by the Company in excess of any insurance coverage could have a
material adverse effect on the Company's business, financial condition and
results of operations.

Need for Additional Capital; Uncertainty of Access to Capital

          Substantial capital will be required to develop the Company's
products, including completing product testing and clinical trials, obtaining
all required United States and foreign regulatory approvals and clearances,
commencing and scaling up manufacturing and marketing its products. Pursuant to
the Company's collaborative arrangements with Abbott, Roche Diagnostics,
Respironics and Welch Allyn, these collaborative partners will either directly
undertake these activities or will fund a substantial portion of these
expenditures. The obligations of the Company's collaborative partners to fund
the Company's capital expenditures is largely discretionary and depends on a
number of factors, including the Company's ability to meet certain milestones
in the development and testing of its products. There can be no assurance that
the Company will meet such milestones or that the Company's collaborative
partners will continue to fund the Company's capital expenditures. Any failure
of the Company's collaborative partners to fund its capital expenditures would
have a material adverse effect on the Company's business, financial condition
and results of operations.

          In addition to funds that the Company expects to be provided by its
collaborative partners, the Company may be required to raise additional funds
through public or private financing, additional collaborative relationships or
other arrangements. The Company believes that its existing capital resources
will be sufficient to satisfy its funding requirements for at least the next 12
months, but may not be sufficient to fund the Company's operations to the point
of commercial introduction of either of its glucose monitoring product concepts.
There can be no assurance that any required additional funding, if needed, will
be available on terms attractive to the Company, or at all, which could have a
material adverse effect on the Company's business, financial condition and
results of operations. Any additional equity financing may be dilutive to
stockholders, and debt financing, if available, may involve restrictive
covenants.


                                     -27-
<PAGE>   28

Uncertainty of Third-Party Reimbursement

          In the United States, patients, hospitals and physicians who purchase
medical devices such as the Company's products, generally rely on third-party
payors, principally federal Medicare, state Medicaid and private health
insurance plans, to reimburse them for all or a portion of the cost of the
medical device. Reimbursement for devices that have received FDA approval has
generally been available in the United States. In addition, certain health care
providers are gradually adopting a managed care system in which such providers
contract to provide comprehensive health care services for a fixed cost per
person. The Company is unable to predict what changes will be made in the
reimbursement methods utilized by third-party health care payors. Although the
Company anticipates that patients, hospitals and physicians will justify the
use of the Company's products by the attendant cost savings and clinical
benefits that the Company believes will be derived from the use of its
products, there can be no assurance that this will be the case. Furthermore,
the Company could be adversely affected by changes in reimbursement policies of
governmental or private health care payors. Any inability of patients,
hospitals, physicians and other users of the Company's products to obtain
sufficient reimbursement from health care payors for the Company's products or
adverse changes in relevant governmental policies or the policies of private
third-party payors regarding reimbursement for such products could have a
material adverse effect on the Company's business, financial condition and
results of operations.

          If the Company obtains the necessary foreign regulatory approvals,
market acceptance of the Company's products in international markets will be
dependent, in part, upon the availability of reimbursement within prevailing
health care payment systems. Reimbursement and health care payment systems in
international markets vary significantly by country and include both government
sponsored health care and private insurance. Although the Company intends to
seek international reimbursement approvals, there can be no assurance that such
approvals will be obtained in a timely manner, if at all. Any failure to
receive international reimbursement approvals could have an adverse effect on
market acceptance of the Company's products in the international markets in
which such approvals are sought.

          In the United States and elsewhere, sales of medical products are
dependent, in part, on the ability of consumers of these products to obtain
reimbursement for all or a portion of their cost from third-party payors, such
as government and private insurance plans. Third-party payors are increasingly
challenging the prices charged for medical products and services. If the
Company succeeds in bringing one or more products to market, there can be no
assurance that these products will be considered cost effective and that
reimbursement to the consumer will be available or sufficient to allow the
Company to sell its products on a competitive basis.

Need to Attract and Retain Key Employees

          The Company's ability to operate successfully and manage its
potential future growth depends in significant part upon the continued service
of certain key scientific, technical, managerial and finance personnel, and its
ability to attract and retain additional highly qualified scientific,
technical, managerial and finance personnel. The officers listed in the
Executive Officers and Directors table included in the Company's 2000 Proxy
Statement comprise the Company's key personnel. None of these key employees has
an employment contract with the Company nor are any of these employees covered
by key person or similar insurance. In addition, if the Company, together with
its collaborative partners, is able to successfully develop and commercialize
the Company's products, the Company will need to hire additional scientific,
technical, marketing, managerial and finance personnel. The Company faces
intense competition for qualified personnel in these areas, many of whom are
often subject to competing employment offers, and there can be no assurance
that the Company will be able to attract and retain such personnel. The loss of
key personnel or inability to hire and retain additional qualified personnel in
the future could have a material adverse effect on the Company's business,
financial condition and results of operations.

Control by Directors, Executive Officers and Affiliated Entities

          The Company's directors, executive officers and entities affiliated
with them, in the aggregate, beneficially owned as of December 31, 1999
approximately 32% of the Company's outstanding Common Stock. These
stockholders, acting together, would be able to control substantially all
matters requiring approval by the stockholders of the Company, including the
election of directors and the approval of mergers and other business
combination transactions.

Potential Volatility of Stock Price

          The stock markets have experienced extreme price and volume
fluctuations that have substantially affected small capitalization medical
technology companies, resulting in changes in the market prices of the stocks
of many such companies that may not have been directly related to their
operating performance. Such broad market fluctuations may adversely affect the
market price of the Company's Common Stock. In addition, the market price of
the Common Stock may be highly volatile. Factors such as variations in the
Company's financial results, changes in the Company's collaborative
arrangements, comments by security analysts, announcements of technological
innovations or new products by the Company or its competitors, changing
government regulations and developments with respect to FDA submissions,
patents and proprietary rights, or litigation may have a material adverse
effect on the market price of the Common Stock.

Anti-Takeover Effect of Certain Charter and Bylaw Provisions on Price of Common
Stock

          Certain provisions of the Company's Certificate of Incorporation and
Bylaws may have the effect of making it more difficult for a third party to
acquire, or of discouraging a third party from attempting to acquire, control
of the Company. Such provisions could limit the price that certain investors
might be willing to pay in the future for shares of the Company's Common Stock.
Certain of these provisions allow the Company to issue Preferred Stock without
any vote or further action by the stockholders, eliminate the right of
stockholders to act by written consent without a meeting and specify procedures
for director nominations by stockholders and submission of other proposals for
consideration at stockholder meetings. Certain provisions of Delaware law
applicable to the Company, including Section 203, which prohibits a Delaware
corporation from engaging in any business combination with any interested
stockholders for a period of three years unless certain conditions are met,
could also delay or make more difficult a merger, tender offer or proxy contest
involving the Company. The possible issuance of Preferred Stock, the procedures
required for director nominations and stockholder proposals and Delaware law
could have the effect of delaying, deferring or preventing a change in control
of the Company, including without limitation, discouraging a proxy contest or
making more difficult the acquisition of a substantial block of the Company's
Common Stock. These provisions could also limit the price that investors might
be willing to pay in the future for shares of the Company's Common Stock.

Lack of Dividends

          The Company has not paid any dividends and does not anticipate paying
any dividends in the foreseeable future.

ITEM 2.   PROPERTIES

          The Company leases approximately 38,000 square feet in Norcross,
Georgia, which comprise the Company's administrative, research and development,
marketing and production facilities and the Company's planned manufacturing
facility. The Company's lease for the portion of this facility housing the
finance department and certain planned manufacturing operations extends through
2001, the portions housing certain research and development operations expire
in June 2002 and March 2003 and the portion housing administration, sales and
marketing, engineering and certain other planned manufacturing operations
expires in March 2001.


ITEM 3.   LEGAL PROCEEDINGS

          In March 2000, SpectRx filed a Demand for Arbitration of certain
disputes arising under its License Agreement with Altea/NIMCO and a former
officer-employee of SpectRx, Jonathan Eppstein, who is also a principal in
Altea/NIMCO. SpectRx seeks an interpretation of certain portions of the License
Agreement relating to SpectRx's obligation to assign future intellectual
property rights and seeks relief and damages for these and other issues. Altea
has subsequently sent a letter to SpectRx purporting to give notice of material
breach of the License Agreement for failure to assign certain intellectual
property rights to Altea or NIMCO and to participate in a joint development
program. The company believes that Altea's claims are without merit, but intends
to abide by the decision of the Arbitration panel as to the proper scope of
SpectRx's duties to assign future intellectual property rights under the
License Agreement and to participate in a joint development program.

           The Company has not paid any dividends since its inception and does
not intend to pay any dividends in the foreseeable future.

         On July 1, 1997, the Company commenced and completed its initial
public offering (the "IPO") of 2,361,699 shares (including 201,699 shares sold
by selling stockholders and including the exercise of the underwriters'
over-allotment option consisting of 160,000 shares) of its Common Stock, $0.001
par value per share, at a public offering price of $7.00 per share pursuant to
a registration statement on Form S-1 (file no. 333-80453) filed with the
Securities and Exchange Commission. All of the shares registered were sold.
Hambrecht & Quist LLC and Volpe Brown Whelan & Company, LLC were the managing
underwriters of the IPO. Aggregate gross proceeds to the Company from the IPO
(prior to deduction of underwriting discounts and commissions and expenses of
the offering) were $15,120,000.

         The Company paid underwriting discounts and commissions of $1,058,400
and other expenses of approximately $896,000 in connection with the IPO. The
total expenses paid by the Company in the IPO were $1,954,400, and the net
proceeds to the Company in the IPO were $13,165,600.

         In conjunction with the amendment of the Abbott Agreement in November
1999, the Company received a total of $5.25 million in November 1999 and
January 2000. The funds received are to be applied to research on the
continuous monitoring technology.

         In February of 2000, the Company sold 400,000 shares of Common Stock
in a private placement transaction to a small group of individual investors for
total gross proceeds of $5.0 million.

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

         Statements in this report which express "belief", "anticipation" or
"expectation" as well as other statements which are not historical fact are
forward looking statements within the meaning of Section 27A of the Securities
Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These
forward looking statements are subject to certain risks and uncertainties that
could cause actual results to differ materially from historical results or
anticipated results, including those set forth under "Risk Factors" in this
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and elsewhere in or incorporated by reference into this report.
Examples of such uncertainties and risks include, but are not limited to,
whether the Company's products in development will prove safe and effective;
whether and when the Company or its strategic partners will obtain approval
from the United States Food and Drug Administration ("FDA") and corresponding
foreign agencies; the Company's need to achieve manufacturing scale-up in a
timely manner, and its need to provide for the efficient manufacturing of
sufficient quantities of its products; the lack of immediate alternate sources
of supply for some critical components of its products; the Company's patent
and intellectual property position; the company's need to fully develop the
marketing, distribution, customer service and technical support and other
functions critical to the success of the Company's potential product lines; the
effectiveness and ultimate market acceptance of the Company's products; and the
dependence of the Company on its strategic partners for funding, development
assistance, clinical trials, distribution and marketing of products developed
by the Company. The following discussion should be read in conjunction with the
Company's Financial Statements and Notes thereto included elsewhere in this
report.

OVERVIEW

          SpectRx was incorporated on October 27, 1992, and since that date has
raised capital through the sale of preferred stock, issuance of debt securities,
the public and private sale of common stock and funding from collaborative
arrangements. Following its initial funding in early 1993, the Company
immediately began research and development activities with the objective of
commercializing less invasive diagnostic, screening and monitoring products. As
part of its business strategy, the Company has selectively established
arrangements with leading medical device companies for the development,
commercialization and introduction of its products. The company has entered into
collaborative arrangements with Abbott, Roche Diagnostics, Respironics, (a
successor to Healthdyne Technologies, Inc.) and Welch Allyn for its glucose
monitoring, diabetes detection, infant jaundice and cancer detection products,
respectively. In December 1996, the Company sublicensed certain technology to
and acquired a 64.8% interest in FluorRx, Inc., a Delaware corporation formed
for the purpose of developing and commercializing technology related to
fluorescence spectroscopy. At December 31, 1999, as a result of a subsequent
financing, SpectRx's interest in FluorRx was 45%.

          The Company has a limited operating history upon which its prospects
can be evaluated. Such prospects must be considered in light of the substantial
risks, expenses and difficulties encountered by entrants into the medical
device industry, which is characterized by an increasing number of
participants, intense competition and a high failure rate. The Company has
experienced operating losses since its inception, and, as of December 31, 1999,
the Company had accumulated deficit of approximately $25.3 million. To date,
the Company has engaged primarily in research and development efforts. The
Company first generated revenues from product sales in 1998 and does not have
significant experience in manufacturing, marketing or selling its products.
There can be no assurance that the Company's development efforts will result in
commercially viable products, that the Company will be successful in
introducing its products, or that required regulatory clearances or approvals
will be obtained in a timely manner, or at all. There can be no assurance that
the Company's products will ever gain market acceptance or that the Company
will ever generate significant revenues or achieve profitability. The
development and commercialization of its products will require substantial
development, regulatory, sales and marketing, manufacturing and other
expenditures. The Company expects its operating losses to continue through 2001
as it continues to expend substantial resources to complete development of its
products, obtain regulatory clearances or approvals, build its marketing,
sales, manufacturing and finance organizations and conduct further research and
development.

          The majority of the Company's revenues and profits are expected to be
derived from royalties and manufacturing profits that the Company will receive
from Abbott, Roche Diagnostics and Respironics resulting from


                                     -33-
<PAGE>   34

sales of its glucose monitoring, diabetes detection and infant jaundice
products, respectively. The royalties and manufacturing profits that the
Company is expected to receive from each of its collaborative partners depend
on sales of such products. There can be no assurance that the Company, together
with its collaborative partners, will be able to sell sufficient volumes of the
Company's products to generate substantial royalties and manufacturing profits
for the Company.

          The Company has entered into collaborative arrangements with Abbott,
Roche Diagnostics, Respironics, and Welch Allyn. The agreements evidencing
these collaborative arrangements grant a substantial amount of discretion to
each collaborative partner. If one or more of the Company's collaborative
partners were to terminate its arrangement with the Company, the Company would
either need to reach agreement with a replacement collaborative partner or
undertake at its own expense the activities handled by its collaborative
partner prior to such termination, which would require the Company to develop
expertise it does not currently possess, would significantly increase the
Company's capital requirements and would limit the programs the Company could
pursue. The Company would likely encounter significant delays in introducing
its products and the development, manufacture and sales of its products would
be adversely affected by the absence of such collaborative arrangements. The
termination of any of the Company's collaborative arrangements would have a
material adverse effect on the Company's business, financial condition and
results of operations.

RESULTS OF OPERATIONS

Comparison of 1999 and 1998

         General. Net losses were approximately $6.6 million, or ($.82) per
share, for the year ended December 31, 1999 compared to approximately $6.6
million, or ($.84) per share, in 1998 due to increases in cost of production,
research and development expenses and administrative expenses. The Company
expects net losses to continue. If the Company is unable to attain certain
milestones under a collaboration agreement, its collaborative partner may not
make milestone payments under, or may terminate altogether, such agreement. If
this were to happen, future net losses would escalate rapidly because of
spending increases necessary to complete research, development and clinical
trials of the Company's products, commence sales and marketing efforts and
establish a manufacturing capability.

          Revenues and Cost of Sales. Revenues increased to approximately $3.3
million for the year ended December 31, 1999 from approximately $1.4 million in
1998. The increase was both in revenue from product sales and milestones from
collaboration partners. Product sales of the Company's BiliCheck(TM) product
grew 75% to approximately $1.4 million in 1999. Revenue from collaborative
agreements, which is generally predicated on achievement of milestones,
increased to approximately $1.9 million for the twelve months ended December
31, 1999 from approximately $600,000 in 1998. Cost of Sales were approximately
$1.7 million for the twelve months ended December 31, 1999, compared to $1.6
million in 1998. All Cost of Sales are related to product sales and those costs
exceeded sales revenues because the Company is in the early stages of product
introduction and has excess capacity.

          Research and Development Expenses. Research and development expenses
increased to approximately $5.2 million for the year ended December 31, 1999
from approximately $4.2 million in 1998. The increase in research and
development expenses was primarily due to increases in prototype materials
($290,000) temporary help ($130,000) and royalty expense ($125,000) primarily
related to the initiatives in continuous glucose monitoring and cancer
detection, in clinical costs ($70,000) for the company's infant jaundice and
diabetes detection products, in legal expenses ($183,000) for patent filings and
patent maintenance and a reduction in reimbursed expenses. The Company expects
research and development expenses to increase in the future as it expands
clinical trials for its products.

         Sales and marketing expenses. Sales and marketing expenses decreased to
approximately $900,000 for the year ended December 31, 1999 from $1.1 million in
1998. The decrease was due primarily to decreases in marketing materials
($112,000), and in travel costs ($56,000) related to the infant jaundice product
introduction and marketing activity. Sales and marketing expenses are expected
to increase in the future, however, as the Company begins to market this product
in additional territories.


                                     -34-
<PAGE>   35
          General and administrative expenses. General and administrative
expenses increased to approximately $2.2 million for the year ended December 31,
1999 from approximately $1.9 million in 1998. The increase in general and
administrative expense was due to the increases in compensation ($112,000), and
outside professional fees ($148,000). General and administrative expenses are
expected to increase in the future as a result of overhead costs associated with
expanded research and development activities and, to a lesser extent, expenses
associated with being a public company.

          Net interest income and other expense. Net interest and other income
decreased to $125,000 for the year ended December 31, 1999 from $783,000 in
1998. This decrease results primarily from recognizing $329,000 of income in
1998 relating to the deconsolidation of FluorRx and lower interest income due
to lower cash balances.

Comparison Of 1998 and 1997

          General. Net losses increased to approximately $6.6 million, or
($.84) per share (on more shares), for the year ended December 31, 1998 from
approximately $5.7 million, or ($1.26) per share, in 1997 due to increases in
cost of production, research and development expenses and marketing expenses.

          Revenues and Cost of Sales. Revenues increased to approximately $1.4
million for the year ended December 31, 1998 from approximately $900,000 in
1997. All of the increase was due to product sales of the Company's
BiliChek(TM) product (approximately $823,000) which was introduced in April
1998. Revenue from collaborative agreements, which is generally predicated on
achievement of milestones, declined to approximately $583,000 for the twelve
months ended December 31, 1998 from approximately $900,000 in 1997. Cost of
Sales were approximately $1.6 million for the twelve months ended December 31,
1998. There was no Cost of Sales in 1997. All Cost of Sales are related to
product sales and those costs exceeded sales revenues because the Company is in
the early stages of product introduction and has excess capacity.

          Research and development expenses. Research and development expenses
increased to approximately $4.2 million for the year ended December 31, 1998
from approximately $3.7 million in 1997. The increase in research and
development expenses was primarily due to increases in compensation ($392,000)
primarily related to new initiatives in continuous glucose monitoring and
cancer detection, in clinical costs ($108,000) for the company's infant
jaundice and diabetes detection products, in legal expenses ($76,000) for
patent filings and patent maintenance, offset by a reduction in FluorRx expense
($550,000) as a result of reporting FluorRx results under the equity method.

          Sales and marketing expenses. Sales and marketing expenses increased
to approximately $1.1 million for the year ended December 31, 1998 from
$835,000 in 1997. The increase was due primarily to increases in advertising
and marketing materials ($110,000), in travel ($70,000) and compensation costs
($50,000) for additional personnel all related to the infant jaundice product
introduction and marketing activity.

          General and administrative expenses. General and administrative
expenses decreased to approximately $1.9 million for the year ended December
31, 1998 from approximately $2.3 million in 1997. The decrease in general and
administrative expense was due to the exclusion of FluorRx administrative
expense in 1998. SpectRx did not consolidate FluorRx during 1998 as its
ownership declined below 50%. (See Note 3 in the accompanying notes). In
addition, production planning and development expenses of approximately
$750,000 were incurred as general and administrative expense in 1997; and
because production began in 1998 all such costs are included in cost of product
sales. These decreases were offset primarily by increases in compensation
($200,000), recruiting expenses ($105,000), and outside professional fees
($85,000).

          Net interest expense and other expense. Net interest and other income
increased to $783,000 for the year ended December 31, 1998 from $194,000 in
1997. This increase results primarily from a one-time gain of $329,000 (net of
previously recognized losses in connection with the deconsolidation of FluorRx)
(See Note 3 in the accompanying notes), and from an increase in interest
received on cash balances received from the initial public offering, available
for a full year in 1998, offset by other expense items.

LIQUIDITY AND CAPITAL RESOURCES

          The Company has financed its operations since inception primarily
through private sales of its debt and equity securities and public sale of its
common stock. From October 27, 1992 (inception) through December 31, 1999, the
Company received approximately $31.2 million in net proceeds from sales of its
debt and equity securities. At December 31, 1999, the Company had cash of
approximately $2.1 million and working capital of approximately $4.8 million.
In November 1999, the Company received $2.75 million from its sale of
redeemable convertible preferred stock to Abbott in conjunction with an
amendment to its Agreement with Abbott for research and development of the
Company's glucose monitoring technology. The Company completed an initial
public offering of its common stock on July 7, 1997 which resulted in net
proceeds received by the Company, of approximately $13.2 million. The Company
currently invests its excess cash balances primarily in short-term,
investment-grade, interest-bearing obligations until such funds are utilized in
operations. Substantial capital will be required to develop the Company's
products, including completing product testing and clinical trials, obtaining
all required United States and foreign regulatory approvals and clearances,
commencing and scaling up manufacturing and marketing its products. Any failure
of the Company's collaborative partners to fund its development expenditures
would have a material adverse effect on the Company's business, financial
condition and results of operations.

          Subsequent to December 31, 1999, the Company received additional
financing. In January 2000 it received $2.5 million for completion of its sale
of Redeemable Convertible Preferred Stock to Abbott, and in February 2000, it
received $5.0 million in gross proceeds from the sale of 400,000 shares of its
Common Stock in a private placement transaction.

          In addition to funds that the Company expects to be provided by its
collaborative partners, the Company may be required to raise additional funds
through public or private financing, additional collaborative relationships or
other arrangements. The company believes that its existing capital resources
will be sufficient to satisfy its funding requirements for at least the next 12
months, but may not be sufficient to fund the Company's operations to the point
of commercial introduction of its glucose monitoring product.

OTHER MATTERS

         Year 2000 Issue Update: We did not experience any significant
malfunctions or errors in our operating or business systems when the date
changed from 1999 to 2000. Based on operations since January 1, 2000, we do not
expect any significant impact to our ongoing business as a result of the year
2000 issue. However, it is possible that the full impact of the date change has
not been fully recognized. We believe that any such problems are likely to be
minor and correctable. In addition, we could still be negatively affected if our
customers or suppliers are adversely affected by year 2000 or similar issues.
Currently we are not aware of any significant year 2000 or similar problems that
have arisen for our customers and suppliers. Expenditures related to year 2000
compliance efforts were less than $40,000.

                          NOTES TO FINANCIAL STATEMENTS

                           DECEMBER 31, 1998 AND 1999


1.       ORGANIZATION AND BACKGROUND

                  SpectRx, Inc. (the "Company") is engaged in the research and
         development of products that offer painless and less invasive
         alternatives to blood tests currently used for glucose monitoring,
         diabetes screening, and infant jaundice. The Company is also in the
         process of developing a cervical cancer detection system. The Company's
         goal is to introduce products that reduce or eliminate pain, are
         convenient to use, and provide rapid results at the point of care,
         thereby improving patient well-being and reducing health care costs.
         The Company's infant jaundice product and products in development for
         glucose monitoring, diabetes screening, and cervical cancer are based
         on proprietary electro-optical and microporation technology that can
         eliminate the pain and inconvenience of a blood sample. The Company has
         entered into collaborative arrangements with Abbott Laboratories
         ("Abbott"), Roche Diagnostics BMC ("Roche"), Respironics, Inc.
         ("Respironics"), and Welch Allyn, Inc. ("Welch Allyn") to facilitate
         the development, commercialization, and introduction of its glucose
         monitoring, diabetes screening, infant jaundice, and cervical cancer
         detection system products, respectively.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         PRESENTATION

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

         CASH AND CASH EQUIVALENTS

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

         INVENTORIES

                  Inventories are stated at lower of cost or market using the
         first-in, first-out method. Inventories are summarized as follows at
         December 31, 1998 and 1999 (in thousands):

         PROPERTY AND EQUIPMENT

                  Property and equipment are recorded at cost. Depreciation is
         computed using the straight-line method over estimated useful lives of
         five to seven years. Expenditures for repairs and maintenance are
         expensed as incurred. Property and equipment are summarized as follows
         at December 31, 1998 and 1999 (in thousands):

</TABLE>

         LONG-LIVED ASSETS

                  The Company periodically reviews the values assigned to
         long-lived assets, such as property and equipment and purchased
         technology, to determine whether any impairments are other than
         temporary. Management believes that the long-lived assets in the
         accompanying balance sheets are appropriately valued.

         PATENT COSTS

                  Costs incurred in filing, prosecuting, and maintaining patents
         are expensed as incurred. Such costs aggregated approximately $286,000,
         $496,000, and $608,000 in 1997, 1998, and 1999, respectively.

         REVENUE RECOGNITION

                  Revenue from product sales is recorded upon shipment of the
         product to the customer.

                  Revenue from collaborative research and development agreements
         is recorded when milestones have been met. Periodic license fee
         payments under collaborative agreements related to future performance
         are deferred and recognized as income when earned.

         RESEARCH AND DEVELOPMENT

                  Research and development expenses consist of expenditures for
         research conducted by the Company and payments made under contracts
         with consultants or other outside parties. All research and development
         costs are expensed as incurred.

         NET LOSS PER SHARE

                  The calculation and presentation of net loss per share are
         presented in accordance with Statement of Financial Accounting
         Standards ("SFAS") No. 128, "Earnings Per Share." Basic earnings per
         share are based on the weighted average number of shares outstanding.
         Diluted earnings per share are based on the weighted average number of
         shares outstanding and the dilutive effect of common stock equivalent
         shares ("CSEs") issuable on the conversion of convertible preferred
         stock (using the if-converted method) and stock options and warrants
         (using the treasury stock method). For all periods presented, CSEs have
         been excluded from weighted average shares outstanding, as their impact
         was antidilutive.

         FAIR VALUE OF FINANCIAL INSTRUMENTS

                  The book values of cash, trade accounts receivable, trade
         accounts payable, and other financial instruments approximate their
         fair values principally because of the short-term maturities of these
         instruments. The fair value of the Company's collaborative partner
         advance is estimated based on the current rates offered to the Company
         for debt of similar terms and maturities. Under this method, the fair
         value of the Company's collaborative partner advance was not
         significantly different than the stated value at December 31, 1999.

         COMPREHENSIVE INCOME

                  The Company has adopted the provisions of SFAS No. 130,
         "Reporting Comprehensive Income," which establishes new rules for the
         reporting and display of comprehensive income and its components;
         however, the Company has no other comprehensive income items as defined
         in SFAS No. 130.

         RECENT ACCOUNTING PRONOUNCEMENTS

                  In June 1998, the Financial Accounting Standards Board
         ("FASB") issued SFAS No. 133, "Accounting for Derivative Instruments
         and Hedging Activities," which establishes accounting and reporting
         standards requiring that every derivative instrument (including certain
         derivative instruments embedded in other contracts) be recorded in the
         balance sheet as either an asset or liability measured at its fair
         value, and changes in the derivative's fair value be recognized
         currently in earnings unless specific hedge accounting criteria are
         met. In June 1999, the FASB issued SAFS No. 137 which deterred the
         effective date of SFAS No. 133 for fiscal quarters of all fiscal years
         beginning after June 15, 2000, although earlier adoption is permitted.
         The Company plans to adopt SFAS No. 133 in the first quarter of fiscal
         2001. Management does not believe the adoption of this statement will
         have a material effect on the financial statements of the Company.

3.       INVESTMENT IN FLUORRX, INC.

                  In December 1996, the Company sublicensed certain technology
         to and acquired a 65% interest in FluorRx, Inc. ("FluorRx"), a
         corporation organized for the purpose of developing and commercializing
         technology related to fluorescence spectroscopy. The Company's interest
         in FluorRx is represented by two seats on the board of directors and
         1.2 million shares of convertible preferred stock purchased for
         $250,000. In December 1997, March 1998, August 1998, and April 1999,
         FluorRx sold additional convertible preferred stock for net cash
         proceeds of $521,000, $429,000, $511,000, and $300,000, respectively.
         The issuance of additional preferred stock reduced the Company's
         ownership (on a converted basis) to 45%.

                  For the year ended December 31, 1997, FluorRx incurred an
         operating loss of $632,000 which was fully consolidated as the Company
         represented FluorRx's sole source of financial support and
         substantially all the capital at risk related to investments and
         advances from the Company. Beginning with the December 1997 funding and
         through the August 1998 funding, the Company consolidated the FluorRx
         losses, but with appropriate allocations to the minority shareholders.
         FluorRx losses recorded by the Company during the fiscal 1998 amounted
         to $306,000. Effective with the August 1998 funding, the Company began
         accounting for its investment in FluorRx under the equity method of
         accounting. In connection with the change in accounting from
         consolidation to the equity method, the Company adjusted its investment
         in FluorRx to $0, which resulted in a one-time gain of $635,000. All
         FluorRx activity (losses and the one-time gain) is reflected in other
         (income) expense in the accompanying statements of operations. The
         Company has also suspended recording losses from its investment in
         FluorRx. Suspended equity losses amounted to $577,000 and $342,000 for
         the years ended December 31, 1998 and 1999, respectively. At December
         31, 1999, the cumulative suspended equity loss amounted to $1,133,000.


                                      -43-
<PAGE>   44

                  In 1997, 1998, and 1999, the Company paid certain patent
         maintenance and minimum royalty costs amounting to $157,000, $57,000,
         and $80,000, respectively, related to technology owned by the Company
         and sublicensed to FluorRx. These costs have been expensed as paid.

4.       STOCKHOLDERS' EQUITY

         INITIAL PUBLIC OFFERING

                  In July 1997, the Company successfully completed its initial
         public offering of common stock. The Company sold 2,160,000 shares of
         common stock, including an underwriter's overallotment of 160,000
         shares, at an initial public offering price of $7. The total proceeds
         of the initial public offering, net of underwriting discounts and
         offering expenses, were approximately $13.2 million. In connection with
         the offering, all outstanding shares of Series A, B, and C preferred
         stock converted into 3,482,762 shares of common stock. Additionally,
         warrants to purchase 559,986 shares of common stock were exercised for
         proceeds of $694,000.

         PREFERRED STOCK

                  In January 1997, the Company authorized 5,000,000 shares of
         preferred stock with a $.001 par value. The board of directors has the
         authority to issue these shares and to fix dividends, voting and
         conversion rights, redemption provisions, liquidation preferences, and
         other rights and restrictions.

                  In November 1999, the board of directors designated 525,000
         shares of the preferred stock as redeemable convertible preferred
         stock. Dividends are payable annually in cash or securities at a rate
         of 6% per annum. The preferred shares, together with any accrued but
         unpaid dividends, are convertible into common shares at the greater of
         $9.39 per share or the average of the closing sales price for 15 days
         prior and 15 days subsequent to the conversion and automatically
         convert on December 31, 2004 at the then conversion rate. The shares
         are mandatorily redeemable at $10 per share, plus accrued but unpaid
         dividends, at the later of December 31, 2002 or 60 days subsequent to
         the date upon which the Company gives notice to Abbott of Abbott's
         right to redeem the shares (which notice may not be given prior to June
         1, 2002). Additionally, the Company may redeem the shares upon
         receiving a conversion notice. The shares have a liquidation preference
         of $10 per share, plus all accrued but unpaid dividends.

                  In November 1999, Abbott subscribed to 525,000 shares of
         Redeemable Convertible Preferred Stock for consideration of $5,250,000
         of which $2,750,000 was received in November 1999 and $2,500,000 was
         received in January 2000.

         CONVERSION OF SUBORDINATED PROMISSORY NOTES

                  In June 1996, the Company issued an 8% convertible
         subordinated promissory note for $250,000. In June 1998, the holder of
         the note converted outstanding principal and interest into 82,637
         shares of common stock at a conversion rate of $3.50.

         STOCK OPTIONS

                  In May 1995, the Company adopted the 1995 Stock Option Plan
         (the "Plan") (as amended), under which 1,428,572 shares of common stock
         are authorized and reserved for use in the Plan. The Plan allows the
         issuance of incentive stock options, nonqualified stock options, and
         stock purchase rights. The exercise price of options is determined by
         the Company's board of directors, but incentive stock options must be
         granted at an exercise price equal to the fair market value of the
         Company's common stock as of the grant date. Options generally become
         exercisable over four years and expire ten years from the date of
         grant. At December 31, 1999, options to purchase 110,494 shares of
         common stock were available for future grant under the Plan.

                  In June 1996, November 1996, and December 1996, the Company
         granted options to purchase 269,652, 8,573, and 60,715, respectively,
         shares of common stock at exercise prices of $.70, $2.45, and $2.45 per
         share, respectively. In connection with the issuance of these options,
         the Company recognized $304,000 as deferred compensation for the excess
         of the deemed value for accounting purposes of the common stock
         issuable upon exercise of such options over the aggregate exercise
         price of such options. This deferred compensation is amortized ratably
         over the vesting period of the options.

                  The Company has elected to account for its stock-based
         compensation plan under Accounting Principles Board Opinion No. 25,
         "Accounting for Stock Issued to Employees," however, the Company has
         computed for pro forma disclosure purposes the value of all options
         granted in each of the three years ended December 31, 1999 using the
         Black-Scholes option pricing model as prescribed by SFAS No. 123,
         "Accounting for Stock-Based Compensation," and using the following
         weighted average assumptions used for grants in 1997, 1998, and 1999:

</TABLE>

         The total values of the options granted during the years ended December
         31, 1997, 1998, and 1999 were computed as approximately $1,587,000,
         $437,000, and $749,000, respectively, which would be amortized over the
         vesting period of the options. If the Company had accounted for these
         plans in accordance with SFAS No. 123, the Company's reported net loss
         and net loss per share for each of the three years ended December 31,
         1999 would have increased by the following pro forma amounts (in
         thousands, except per share amounts):

         WARRANTS

                  In connection with the November 1995 and April 1996 note sales
         (Note 4), the Company issued warrants to purchase 317,613 shares of
         common stock at an exercise price per share of 20% of the price per
         share paid in the next equity financing of $5,000,000 or more,
         inclusive of the notes and warrants subject to conversion. In August
         1996, the exercise price was set at $1.12 per share.

                  Upon the close of the initial public offering, all outstanding
         warrants to purchase 559,986 shares of common stock were exercised
         providing proceeds of approximately $694,000.

         EMPLOYEE STOCK PURCHASE PLAN

                  In connection with the offering, the Company adopted an
         employee stock purchase plan under which the Company may issue up to
         214,286 shares of common stock. Eligible employees may use up to 10% of
         their compensation to purchase, through payroll deductions, the
         Company's common stock at the end of each plan period for 85% of the
         lower of the beginning or ending stock price in the plan period. At
         December 31, 1999, there were 185,948 shares available for future
         issuance under the Plan.

5.       INCOME TAXES

                  The Company has incurred net operating losses ("NOLs") since
         inception. As of December 31, 1999, the Company had net operating loss
         carryforwards of approximately $24,357,000 available to offset its
         future income tax liability. The NOL carryforwards begin to expire in
         2007. The Company has recorded a valuation allowance for all NOL
         carryforwards. Utilization of existing NOL carryforwards may be limited
         in future years if significant ownership changes have occurred.

                  Components of deferred tax assets are as follows at December
         31, 1998 and 1999 (in thousands):

6.       COMMITMENTS AND CONTINGENCIES

         Future minimum rental payments at December 31, 1999 under
         noncancellable operating leases for office space and equipment are as
         follows (in thousands):

                          2002                         102
</TABLE>

                  Rental expense was $215,000, $261,000, and $225,000 in 1997,
         1998, and 1999, respectively.

                  In the past, the Company has been subject to certain asserted
         and unasserted claims against certain intellectual property rights
         owned and licensed by the Company. A successful claim against
         intellectual property rights owned or licensed by the Company could
         subject the Company to significant liabilities third parties, require
         the Company to seek licenses from third parties, or prevent the Company
         from selling its products in certain markets or at all. In the opinion
         of management, there are no known claims against the Company's owned or
         licensed intellectual property rights that will have a material adverse
         impact on the Company's financial position or results of operations.

7.       RELATED-PARTY TRANSACTIONS

                  In connection with a June 1994 sale of restricted stock, the
         Company loaned two officers of the Company $48,000, of which $31,000 is
         outstanding at December 31, 1999. These loans are secured by common
         stock of the Company held by the officers, bear interest at 6% per
         annum, and become payable on December 31, 2001. Outstanding balances
         are classified as a reduction of stockholders' equity in the
         accompanying balance sheets.

                  In October 1996, the Company loaned two officers a total of
         $400,000. The loans are secured by common stock of Laser Atlanta
         Optics, Inc. ("LAO"). The Company and LAO are related through a common
         group of shareholders. The loans bear interest at 6.72% per annum and
         are due and payable in cash in October 2001. Outstanding balances are
         reflected as due from related parties in the accompanying balance
         sheets.

                  In 1997, a portion of the proceeds from the Company's sale of
         convertible subordinated promissory notes and Series A and B preferred
         stock were received from officers, directors, or other parties related
         to the Company as a result of previous equity transactions. The sales
         were conducted concurrently with and on the same terms as those entered
         into with unrelated parties.

8.       LICENSE AND TECHNOLOGY AGREEMENTS

                  As part of the Company's efforts to conduct research and
         development activities and to commercialize potential products, the
         Company, from time to time, enters into agreements with certain
         organizations and individuals that further those efforts but also
         obligate the Company to make future minimum payments or to remit
         royalties ranging from 1% to 3% of revenue from the sale of commercial
         products developed from the research.

                  The Company generally has the option not to make required
         minimum royalty payments, in which case the Company loses the exclusive
         license to develop applicable technology. Minimum required payments to
         maintain exclusive rights to licensed technology are as follows at

3.       RESEARCH AND DEVELOPMENT

         3.1 Continuous Product Research Program. The Continuous Product
Research Program for ABBOTT primarily will be conducted by SPECTRX at its
facility in Norcross, Georgia. SPECTRX will have control over the Continuous
Product Research Program provided that SPECTRX is working toward achieving the
Continuous Product Research Program Specifications, unless it is transferred to
ABBOTT pursuant to Section 3.3(B), in which case ABBOTT will have control. All
deviations from or modifications to the Continuous Product Research Program
Specifications will be in writing and signed by both parties. SPECTRX shall
Diligently undertake, pursue and support those activities under the Continuous
Product Research Program required to achieve the Continuous Product Research
Program Specifications. For avoidance of doubt, non-achievement of the
Continuous Product Research Program Specifications does not necessarily mean
lack of Diligence on the part of either party. ABBOTT shall Diligently
undertake, pursue, and support those research activities to which the parties
have mutually agreed in writing shall be carried out by ABBOTT as part of the
Continuous Product Research Program, including a specific reference to what
performance requirements constitutes Diligence with regard to such activities.
However, notwithstanding such research activities by ABBOTT, other than ABBOTT's
obligation of Diligence in the preceding sentence, ABBOTT shall have no
responsibility for achievement of, nor any liability for failure to achieve, the
Continuous Product Research Program Specifications, no matter what is the reason
for such failure. Further, after ABBOTT delivers a Development Program
Notification for the first Continuous Product under this Agreement, neither
ABBOTT nor SPECTRX shall have

(*)      Confidential treatment requested pursuant to a request for confidential
         treatment filed with the Securities and Exchange Commission. Omitted
         portions have been filed separately with the Commission.



                                       10

further obligations with regard to any research activities or Diligence
obligations with regard to any other Continuous Product that ABBOTT may
determine to develop or any improvements to any Continuous Product that ABBOTT
may make. Diligence requirements for development of the first Continuous Product
which is actually commercialized remain in accordance with Section 3.4 of the
Third Amendment . If SPECTRX and ABBOTT determine that certain activities have
the potential for intellectual property disputes then the parties will negotiate
an agreement to cover such specific activities including relevant intellectual
property issues before commencing such activities where possible.

         3.2 Research Oversight Committee. Within thirty (30) days of the Third
Amendment Effective Date, ABBOTT and SPECTRX will appoint members to a committee
to review the work under the Continuous Product Research Program ("Research
Oversight Committee"). The parties will define the number of members, duties and
frequency of meetings (which shall not be less than every two (2) months) within
thirty (30) days of the Third Amendment Effective Date. Notwithstanding the
foregoing, upon thirty (30) days prior notice by ABBOTT, SPECTRX will disclose
such data and other information related to the Continuous Product Research
Program as reasonably requested by ABBOTT. Prior to each Research Oversight
Committee meeting, ABBOTT and SPECTRX shall each provide to the other a written
report of its respective activities under the Continuous Product Research
Program, including relevant data, a description of progress made, and a
discussion of any plan variances or problems encountered.

         3.3 Completion, Termination or Transfer of the Continuous Product
Research Program.

                  (A)      ABBOTT will have no obligation to pay any wind-down
                           or other expenses of SPECTRX if the Continuous
                           Product Research Program is successfully completed,
                           terminated or transferred under this provision or any
                           other provision of the Third Amendment or the
                           Agreement; provided, however, that SPECTRX may
                           utilize the funds from ABBOTT's purchase of preferred
                           stock as set forth in Section 5.5 of this Third
                           Amendment for such expenses.

                  (B)      ABBOTT may, in its sole discretion, after (*), elect
                           to transfer the Continuous Product Research Program
                           to ABBOTT and/or redefine the Continuous Product
                           Research Program Specifications and to cease funding
                           such Continuous Product Research Program as conducted
                           by SPECTRX if SPECTRX has not achieved the (*)
                           Milestone by such date. If ABBOTT makes such
                           election, ABBOTT will give SPECTRX forty-five (45)
                           days prior written notice of such election. For
                           clarification, but not limitation, ABBOTT may give


(*)      Confidential treatment requested pursuant to a request for confidential
         treatment filed with the Securities and Exchange Commission.Omitted

                           such notice any time after (*). At the end of the
                           forty-five (45) day notice period if ABBOTT transfers
                           the Continuous Product Research Program to ABBOTT,
                           ABBOTT will Diligently undertake the research
                           activities in an attempt to achieve acceptable
                           performance to meet the Continuous Product Research
                           Program Specifications and expenditures for that
                           purpose shall be in accordance with Section
                           3.4(A)(2). If ABBOTT notifies SPECTRX of its interest
                           to transfer the Continuous Product Research Program,
                           SPECTRX will promptly, after such notice, (i)
                           transfer to ABBOTT all information, all data and half
                           of the (*) Products related to the Continuous Product
                           Research Program as conducted by SPECTRX; (ii)
                           provide shared access to all materials, hardware,
                           software and pilot manufacturing lines related to the

                           SPECTRX for a reasonable period of time until ABBOTT
                           is able to develop or acquire its own capabilities in
                           these areas, and (iii) provide reasonable assistance
                           to ABBOTT in transferring such activities to ABBOTT,
                           and ABBOTT shall reimburse SPECTRX for its reasonable
                           direct expenses, excluding the cost of personnel time
                           required to physically transfer the Continuous
                           Product Research Program materials. If only one
                           hardware item or other item exists, ABBOTT and
                           SPECTRX will develop a plan that allows use by both
                           parties, including the sharing of any operating costs
                           of such item.

                  (C)      ABBOTT may elect to cease funding the Continuous
                           Product Research Program as either conducted by
                           SPECTRX or ABBOTT, including declining to make any

                           together with expenditures made or to be made by
                           SPECTRX for the Continuous Product Research Program,
                           are in excess of the funding by the preferred stock
                           purchase, then such additional expenditures shall be
                           separately funded by ABBOTT with prior written
                           approval of ABBOTT. If ABBOTT determines, and SPECTRX
                           agrees, to maintain a portion of the Development
                           Program at SPECTRX, such determination and agreement
                           to be made at the time of Development Program
                           Notification, then ABBOTT and SPECTRX shall establish
                           a mutually agreeable plan and budget for such
                           Development Program within ninety (90) days of the
                           date the Development Program Notification is
                           delivered to SPECTRX. Such Development Program plan
                           will require that SPECTRX at a minimum provide the
                           same resources and expertise, as it has used during
                           the Continuous Product Research Program, or their
                           equivalents as agreed to by ABBOTT and SPECTRX.
                           ABBOTT and SPECTRX shall agree on interim activities,
                           if any, and ABBOTT shall provide interim funding for
                           such activities between Development Program
                           Notification and establishment of the mutually
                           agreeable plan. If SPECTRX is concurrently pursuing
                           development of the SPECTRX Continuous Product, then
                           SPECTRX will also provide equivalent resources,
                           expertise, and priorities for the ABBOTT Continuous
                           Product Development Program. If ABBOTT believes that
                           there is a conflict of interest between the SPECTRX
                           Continuous Product development and the Continuous
                           Product Development Program that materially impacts
                           ABBOTT's Continuous Product Development Program, then
                           ABBOTT shall notify SPECTRX in writing describing the
                           specifics of the conflict of interest. Upon such
                           written notification, the parties will meet to
                           attempt to resolve any issue and SPECTRX shall have
                           thirty (30) days to correct the conflict of interest.
                           If SPECTRX does not correct such conflict of interest
                           within such thirty (30) day period, then ABBOTT (1)
                           will have no obligation to enter into a Supply
                           Agreement or may terminate an existing Supply
                           Agreement for the manufacture of (*)s by SPECTRX; (2)
                           ABBOTT may immediately cease funding SPECTRX
                           activities under the Continuous Product Development
                           Program; and (3) then SPECTRX will promptly transfer
                           to ABBOTT everything related to the Continuous
                           Product Development Program, including, but not

                           transferring such activities and items to ABBOTT.
                           Such transfer shall not include information, data,

                           program for the SPECTRX Continuous Product. If any of
                           these items are common between the ABBOTT program and
                           the SPECTRX program, then the parties will negotiate
                           in good faith on an approach to split or share such
                           items. For clarification, neither the fact that
                           SPECTRX is developing the SPECTRX Continuous Product,
                           nor the fact that it has entered into a Third Party
                           relationship, shall be deemed in and of itself to
                           constitute a conflict of interest for the purposes of
                           this Section 3.5(A).

                           has been achieved less than (*) before (*), and
                           ABBOTT has not delivered the Development Program
                           Notification for such Product by (*), then ABBOTT
                           shall have (*) from the date of (*) Milestone
                           achievement to deliver the Development Program
                           Notification and will be obligated to pay for any
                           Continuous Product Research Program expenses or any
                           development activities expenses for such Continuous
                           Product requested and authorized in writing by ABBOTT
                           and incurred by SPECTRX after (*) until the date of
                           Development Program Notification. In such case,
                           SPECTRX will have no obligation to continue the

                           Research Program after (*) unless ABBOTT and SPECTRX
                           agree to such activities commencing (*).

         3.6      Development Program - Non-Continuous Product.

                  (A)      At any time prior to (*), ABBOTT may deliver the
                           Development Program Notification to SPECTRX if ABBOTT
                           determines to commence the Development Program for
                           the Non-Continuous Product. ABBOTT shall have
                           complete control of the Development Program for the
                           Non-Continuous Product or Non- Continuous Products
                           under this Agreement. However, such control by ABBOTT
                           shall not affect the timing of Milestones or the rate
                           of royalties for such Non-Continuous Product or
                           Non-Continuous Products.

                  (B)      If ABBOTT does not Diligently pursue research
                           activities beginning (*), and spend at the minimum
                           rate of (*) per year on the Non-Continuous Product
                           research activities beginning (*) and ending upon

                           ABBOTT notifies SPECTRX that it is terminating the
                           Continuous Product Research Program or Development
                           Program, then ABBOTT must deliver the Non-Continuous

                           prior to (*) from such termination date for the

                  (A)      For the Continuous Product and the Non-Continuous
                           Product on which ABBOTT delivers a Development
                           Program Notification to SPECTRX, ABBOTT shall
                           Diligently use its commercially reasonable efforts to
                           achieve:

                           (1)      submission of a Regulatory Filing with the
                                    FDA within (*) (if a 510K Filing submission
                                    is to be made) (*) (if a PMA submission is
                                    to be made) after delivery of such
                                    Development Program Notification for such
                                    Product;

                           (2)      the First Shipment Date for such Product
                                    within (*) after delivery of such

                           failure is not due to a lack of SPECTRX Diligence in
                           fulfilling its responsibilities, if any, under the
                           Development Program, then prior to the end of the
                           period set forth in Section 3.7(A)(1) or such
                           extended period agreed by the parties, ABBOTT may
                           extend such period by (*) by written notice of
                           extension to SPECTRX and within thirty (30) days of
                           such notice, payment to SPECTRX of (*)set forth in
                           Section 5.1(A)(4). ABBOTT further may extend such
                           period by an additional (*) if SPECTRX has commenced
                           developing its SPECTRX Continuous Product and if
                           ABBOTT is Diligently working toward a Regulatory
                           Filing to the FDA. If ABBOTT's failure under this
                           Section 3.7(B) is due to a lack of SPECTRX Diligence,
                           if any, then any such deadline will be extended to
                           the extent impacted by SPECTRX's lack of Diligence.

                  (C)      If the First Shipment Date has not occurred and such
                           failure is not due to a lack of SPECTRX Diligence in
                           fulfilling its responsibilities, if any, under the
                           Development Program, then prior to the end of the (*)
                           period set forth in Section 3.7(A)(2), as the case
                           may be, ABBOTT may extend such period (*) ,
                           respectively, by written notice of extension to
                           SPECTRX and within thirty (30) days of such notice,
                           payment to SPECTRX of (*). ABBOTT further may extend
                           such period by an additional (*) if SPECTRX has
                           commenced developing its SPECTRX Continuous Product
                           and if ABBOTT is Diligently working toward the First
                           Shipment Date. If ABBOTT's failure under this Section
                           3.7(C) is due to a lack of SPECTRX Diligence, then
                           such deadlines will be extended to the extent
                           impacted by SPECTRX's lack of Diligence.

                  (D)      Unless the parties agree to extend such time for the
                           Regulatory Filing in Section 3.7(A)(1) above, if
                           ABBOTT (i) has not made such Regulatory Filing within
                           the period set forth in Section 3.7(A)(1) or an
                           extended period pursuant to Section 3.7(B) or (ii) if
                           the First Shipment Date has not occurred within the
                           period set forth in Section 3.7(A)(2) or an extended
                           period pursuant to Section 3.7(C), then upon written
                           notice from SPECTRX, ABBOTT shall have no further

                           and as a result this Agreement terminates in
                           accordance with Section 3.8(A), and a Regulatory
                           Filing did not occur due to one of the events set
                           forth in Section 3.1(B) of the Agreement, then
                           SPECTRX shall not be entitled to the license in
                           Section 6.2(C) of the Agreement and grant back of
                           rights set forth in Section 7.1 of the Agreement or

                           Amendment upon termination of the Agreement.

                  (E)      If ABBOTT has made a payment for a particular
                           extension under Section 3.7(B) and/or 3.7(C) for
                           either the first Continuous Product or the first
                           Non-Continuous Product, then if ABBOTT requires the
                           same extension for the first Product of the other
                           type (Non-continuous Product or Continuous Product,
                           as the case may be) under a Development Program,
                           ABBOTT will receive such extension (*) upon prior
                           written notification to SPECTRX within the original
                           time period; provided, that, ABBOTT is employing
                           Diligent commercially reasonable efforts to meet the
                           requirements as set forth in Section 3.7(A) (1) or
                           (2) for such Product and requires such extension to
                           meet such requirements.

                  (F)      If ABBOTT does not deliver the Development Program
                           Notification for a Continuous Product by the
                           prescribed date or if ABBOTT notifies SPECTRX that it
                           is terminating all Continuous Product Research or
                           Development Programs, then in the first (*) following
                           the prescribed date or notice of such termination,
                           ABBOTT will Diligently pursue research activities or
                           Development Program, (including spending at the rate
                           of at least (*) on Non-Continuous Product research
                           activities or Development Program and, thereafter, at
                           the rate of (*) per each (*) period until completion
                           or termination of such program). If ABBOTT does not
                           meet these requirements, then SPECTRX may terminate
                           ABBOTT's rights to all Non-Continuous Products upon
                           written notice to ABBOTT and the Agreement will
                           terminate in accordance with Section 3.8(A).

         3.8      Termination of all Programs.

                  (A)      Prior to the First Shipment Date, if ABBOTT ceases
                           funding all research activities as set forth in the
                           Agreement, and does not deliver any Development
                           Program Notifications within the prescribed times or
                           ceases all or does not commence any Development
                           Program with regard to either the Continuous Product
                           or Non-Continuous Product, and the parties have not
                           agreed otherwise, then this Agreement shall terminate
                           upon receipt of written notice of same from one party
                           to the other, subject to

                           Sections 10.3 and 10.4 of the Agreement. In any case,
                           prior to the First Shipment Date, if rights to both
                           the Continuous Product and the Non-Continuous Product
                           are relinquished by ABBOTT, this Agreement shall
                           terminate.

                  (B)      After the First Shipment Date, if rights to both the
                           Continuous Product and the Non-Continuous Product are
                           relinquished by ABBOTT, this Agreement shall
                           terminate.

                  (C)      If ABBOTT ceases funding any research activities,
                           ceases any research activities or any development
                           activities which are required by the Agreement for
                           the Continuous Product or the Non-Continuous Product,
                           ABBOTT shall notify SPECTRX within thirty (30) days
                           of each such cessation unless otherwise provided by
                           this Third Amendment or the Agreement.

         3.9 Reports. ABBOTT and SPECTRX each will provide the other with
quarterly reports on its activities under either the Continuous Product Research
Program or Research Program and reports every six (6) months for activities
under Development Programs, including summary data generated, to the extent
necessary to demonstrate that such party is meeting its Diligence requirements
(including spending requirements) set forth in the Agreement. Such reports shall
redact any data or other information which is subject to a confidentiality
agreement between ABBOTT and a Third Party and any data which is outside the
scope of ABBOTT's obligations under this Agreement. This requirement for reports
for a Research Program and any Development Programs shall not commence until a
party has Diligence requirements for such Research Program or Development
Program as set forth in Sections 3.5, 3.6 and/or 3.7, as the case may be. Such
reports to the Research Oversight Committee will satisfy reporting requirements
under this Section 3.9.

         3.10 R & D Expense Records and Audit. ABBOTT and SPECTRX each shall
keep and maintain records of amounts spent on the Continuous Product Research
Program, the Research Program and Development Programs conducted in accordance
with the provisions of Article 3 of the Agreement and Article 3 of this Third
Amendment, except for Abbott's requirement for the Research Program and
Development Program which shall commence upon the date it has Diligence
requirements for such Research Program or Development Program as set forth in
Sections 3.5, 3.6 and/or 3.7, for a period of two (2) years after the period to
which such records relate. During this period, such records shall be open to
inspection upon reasonable written notice by one party to the other party. Such
inspection shall be performed by a nationally recognized independent certified
public accountant selected by the party requesting the audit and approved by the
party to be audited, which approval shall not be unreasonably withheld. All
expenses of such inspection shall be borne by the party requesting the audit;
provided that, if the audited party is found to have overstated its spending by
more than (*) any amounts required to be spent for the Continuous Product
Research

Program, Research Program or Development Programs under Article 3, and as a
result is non-compliant with its Diligence requirements, then the audited party
shall bear such expenses. The independent certified public accountant shall sign
a confidentiality agreement and shall then have the right to examine the records
kept pursuant to this Section and report findings (but not the underlying data)
of the examination to the party requesting the audit as is necessary to evidence
that records were or were not maintained and expenditures made as required by
this Article 3. A copy of any report provided to the party requesting the audit
by the independent certified public accountant shall be given concurrently to
the audited party.

4.       SPECTRX CONTINUOUS PRODUCT

         4.1 Development by SPECTRX. If ABBOTT delivers a notice to materially
redefine the Continuous Product Research Program Specifications or of the
transfer to ABBOTT of the Continuous Product Research Program or to extend the
Development Program Notification date for the Continuous Product in accordance
with the Agreement, then SPECTRX may determine to develop not earlier than (*),
one (1) Continuous Product, for its own benefit, such research and development
to be funded by SPECTRX ("SPECTRX Continuous Product"). SPECTRX shall have the
right to modify SPECTRX Continuous Product to eliminate the use of any or all
Licensed Rights (as defined in Section 4.2(B)). Notwithstanding the foregoing,
SPECTRX will not have such rights to develop a SPECTRX Continuous Product until
after (*) if ABBOTT funds the Continuous Product Research Program at SPECTRX
after (*) with a commercially reasonable funding level agreed to by the parties
in order to develop a (*) Product that meets the Continuous Product Research
Program Specifications as first specified in Appendix 2.7. SPECTRX will provide
ABBOTT with ten (10) days prior written notice prior to commencing development
of a SPECTRX Continuous Product. One Continuous Product means (*) Continuous
Product which shall be sold (*) and pursuant to a (*) and which, after
commercial launch, (*). Notwithstanding anything in this Section 4.1, (A) if the
(*) Milestone is achieved between (*), and (*),, and ABBOTT delivers Development
Program Notification within sixty (60) days of SPECTRX's achievement of the (*)
Milestone, or (B) if ABBOTT provides Development Program Notification to SPECTRX
between (*), and (*), after funding the Continuous Product Research Program at
SPECTRX after (*), as set forth in this Section 4.1, then SPECTRX shall not have
the right to develop a SPECTRX Continuous Product.

         4.2 License to SPECTRX.

         (A)      If the criteria of Section 4.1 are met and within the time
                  period that ABBOTT has extended the deadline for delivering
                  the Product Development Notification ABBOTT receives a written
                  notification from SPECTRX of its election to develop such
                  SPECTRX Continuous Product, ABBOTT shall grant to SPECTRX a
                  royalty-bearing, non-exclusive license, without the right to
                  sublicense,

                           made, use, sell and import the SPECTRX Continuous
                           Product in the Territory, (*). ABBOTT and SPECTRX
                           shall enter into a license agreement which shall
                           include the grant set forth in this Section 4.2(A),
                           the royalty in Section 4.4 and other customary terms
                           and conditions, similar where appropriate, to those
                           license terms set forth in the Agreement.

                  (B)      Upon receiving SPECTRX's election to develop such
                           SPECTRX Continuous Product, ABBOTT shall grant to
                           SPECTRX a royalty-bearing, non-exclusive license,
                           without the right to sublicense, under those ABBOTT
                           patent rights and know-how ("Licensed Rights") which
                           have been incorporated into the Continuous Product at
                           the earliest of the following: (1) date of ABBOTT's
                           notice to materially redefine the Continuous Product
                           Research Program Specifications as set forth in
                           Section 4.1; or (2) date of ABBOTT's notice of the
                           transfer to ABBOTT of the Continuous Product Research
                           Program as set forth in Section 4.1; or (3) date of
                           SPECTRX's notice as set forth in Section 4.2(A), to
                           use, sell, and import the SPECTRX Continuous Product
                           in the Territory. ABBOTT and SPECTRX shall enter into
                           a license agreement for such Licensed Rights under
                           commercially reasonable royalty rates and other
                           customary terms and conditions, similar where
                           appropriate, to those license terms set forth in the
                           Agreement.

         4.3 Manufacturing Rights.

                  (A)      If SPECTRX is granted a license under Section 4.2(B),
                           ABBOTT shall have the option to manufacture for
                           SPECTRX those items covered by the Licensed Rights.
                           SPECTRX shall deliver notification of such
                           anticipated date to ABBOTT within (*) prior to
                           SPECTRX's commercially reasonable anticipated date of
                           the first commercial sale of the SPECTRX Continuous
                           Product. ABBOTT may exercise its option hereunder by
                           written notice to SPECTRX (*) days of receiving
                           SPECTRX's notification. If ABBOTT delivers such
                           notice to SPECTRX, SPECTRX and ABBOTT shall enter
                           into a manufacturing agreement under commercially
                           reasonable terms agreed upon by the parties. If
                           ABBOTT does not exercise its option within the
                           designated time period, then ABBOTT shall modify
                           SPECTRX's license grant set forth in Section 4.2(B)
                           to extend it to "make and have made."

                           4.4(B) of the SPECTRX Continuous Product and (*) and
                           the (*) of ABBOTT Continuous Product and (*), then
                           ABBOTT shall have the option to transfer such
                           manufacture of (*)s to ABBOTT or a Third Party
                           designated by ABBOTT. ABBOTT may exercise its option
                           at any time after SPECTRX exceeds the threshold set
                           forth in this Section by written notice to SPECTRX.
                           ABBOTT and SPECTRX will agree on a commercially
                           reasonable transition plan and timetable to transfer
                           such manufacturing to ABBOTT or ABBOTT's designee and
                           SPECTRX will provide the necessary documentation and
                           assistance for such transfer. SPECTRX will provide
                           the necessary documentation and limited assistance at
                           its own expense and ABBOTT shall pay for all other
                           expenses associated with such transfer.

         4.4 Royalty.

                  (A)      In consideration for the license granted under
                           Section 4.2(A), SPECTRX shall pay to ABBOTT a royalty
                           as set forth in Section 4.4(B) on (*) of the SPECTRX
                           Continuous Product and (*) in the Territory applying
                           the same criteria to SPECTRX as in (*) for ABBOTT,
                           including the same provisions for deductions as set
                           forth in Section 1.23(A) of the Agreement and Section
                           5.6(B) of the Third Amendment. No royalty shall be
                           due for sales through ABBOTT or by ABBOTT under
                           distributor rights negotiated under Section 4.5 or
                           for items manufactured by ABBOTT for SPECTRX that are
                           related to the SPECTRX Continuous Product; provided,
                           that royalties also shall be due under the
                           circumstances that would call for ABBOTT to pay
                           royalties on its (*) under Section 4.2(D) of the
                           Agreement.

                  (B)      Prior to First Shipment Date of Abbott's Continuous
                           Product, royalties will be calculated on (*) at a
                           royalty rate of (*). Thereafter, the royalty rate
                           will be based on SPECTRX (*) (as defined in Section
                           4.4(B)(1)) in accordance with Appendix 4.4. Royalties
                           shall be calculated as follows:

                           (1)      It is anticipated that a majority of
                                    SPECTRX's (*), if any, of the SPECTRX
                                    Continuous Product and (*) will be made (*)
                                    for each year, total SPECTRX actual (*) of
                                    the SPECTRX Continuous Product and (*) shall
                                    be (*) unless SPECTRX or ABBOTT can

                                    for such year shall be determined by
                                    applying such SPECTRX (*) to the chart in
                                    Appendix 4.4.

                           (2)      The royalty payment shall be determined by
                                    the formula (*) where (*) is the applicable
                                    royalty rate in Appendix 4.4; (*) is the
                                    total SPECTRX (*); and (*) is a fraction,
                                    the numerator of which is that portion of
                                    the SPECTRX (*) applicable to such royalty
                                    rate and the denominator of which is the
                                    total (*).

                  (C)      Any sales of the SPECTRX Continuous Product and/or
                           (*) by a Third Party in which SPECTRX has a material
                           financial interest shall be deemed sales by SPECTRX
                           and such sales shall be included in (*) for purposes
                           of calculation of the royalty payment under this
                           Article.

         4.5 Right of First Negotiation - Distribution Rights. ABBOTT shall have
the right of first negotiation for the exclusive right to the distribution of
the SPECTRX Continuous Product which right of first negotiation may be exercised
as follows:

                  (A)      Within (*) prior to SPECTRX's commercially reasonable
                           anticipated date of first commercial sale of the
                           SPECTRX Continuous Product, SPECTRX shall deliver
                           written notification to ABBOTT regarding its right of
                           first negotiation. SPECTRX shall not engage in any
                           discussions with any Third Party concerning such
                           distribution until ABBOTT's right of first
                           negotiation terminates in accordance with Section
                           4.5(C) or 4.5(D).

                  (B)      ABBOTT shall have (*) after receipt of the notice and
                           the report in Section 4.5(C) to provide a written
                           response indicating whether ABBOTT is interested or
                           not in such distribution rights.

                  (C)      At the time that the notice is delivered to ABBOTT,
                           SPECTRX shall provide to ABBOTT a full report on the
                           SPECTRX Continuous Product, including technical
                           specifications and performance of the SPECTRX
                           Continuous Product reasonably necessary to assess
                           performance and marketability and any other
                           information reasonably requested by ABBOTT. Within
                           (*) after receipt of such report, ABBOTT may send to
                           SPECTRX an initial proposal containing proposed
                           financial and other material terms for such
                           distribution relationship (the "ABBOTT Proposal"). If
                           ABBOTT does not send an ABBOTT Proposal within such
                           period of time, then ABBOTT's right of first
                           negotiation with regard to such distribution rights
                           shall terminate.

                  (D)      If ABBOTT delivers an ABBOTT Proposal to SPECTRX,
                           SPECTRX and ABBOTT shall promptly enter into good
                           faith negotiations towards a distribution agreement
                           upon mutually agreed terms and conditions. Subject to
                           SPECTRX making all reasonable efforts to meet and
                           negotiate with ABBOTT on a timely basis and in good
                           faith, if SPECTRX and ABBOTT fail to reach mutual
                           agreement on a term sheet covering the material terms
                           and conditions of a distribution agreement within (*)
                           from the receipt of the ABBOTT Proposal by SPECTRX,
                           or fail to execute a definitive distribution
                           agreement within (*) of such receipt, then upon
                           written notice from SPECTRX, ABBOTT shall have no
                           further right of first negotiation with regard to
                           such distribution rights except as set forth in
                           Section 4.5(E).

                  (E)      (1)      If, during  the (*) period subsequent to the
                                    process set forth in Section 4.5(A)-(D),
                                    SPECTRX negotiates proposed terms for a
                                    distribution agreement for the SPECTRX
                                    Continuous Product with a Third Party under
                                    terms and conditions that are more favorable
                                    to the Third Party than those originally
                                    proposed during negotiation with ABBOTT
                                    (taking into consideration all relevant
                                    terms of both proposals, including, but not
                                    limited to, quantities, any minimum purchase
                                    obligations, type of distribution rights,
                                    type of Third Party and other agreement
                                    obligations) ("More Favorable Terms"), then
                                    SPECTRX by written notice promptly shall
                                    inform ABBOTT of the More Favorable Terms
                                    and ABBOTT shall have (*) to accept such
                                    More Favorable Terms by written notice to
                                    SPECTRX.

                           (2)      If ABBOTT and SPECTRX fail to enter into a
                                    distribution relationship pursuant to
                                    Section 4.5(D), and prior to entering into
                                    any other definitive distribution agreement
                                    with a Third Party, SPECTRX makes
                                    significant improvements to the SPECTRX
                                    Continuous Product, then ABBOTT shall have
                                    the right of first negotiation with regard
                                    to such improved SPECTRX Continuous Product
                                    under the same process as set forth in this

SPECTRX's election to develop a SPECTRX Continuous Product, if SPECTRX is

                                    described in the Continuous Product Research

                                    Milestone shall be deemed achieved if ABBOTT
                                    delivers the Development Program
                                    Notification in Section 5.1(A)(3) for either

                           (3)      (*) of delivery by ABBOTT to SPECTRX of a
                                    Development Program Notification.

                           (4)      (*) of submission by ABBOTT of a Regulatory
                                    Filing with the FDA for a Product.

                           (5)      (*) of ABBOTT receiving the first written
                                    approval to market from the FDA for a

                  (B)      The payment for each Milestone shall be made only
                           once, notwithstanding that the Milestone is met for
                           more than one Product. The total consideration due
                           from ABBOTT under this Section 5.1 shall not exceed
                           (*).

                  (C)      ABBOTT at its election by the delivery of a written

                           may use a portion, up to one-half, of its payment

                           5.1(A)(2) and Section 5.1(A)(3) to purchase shares of
                           common stock of SPECTRX ("SPECTRX Common Stock") as
                           detailed in the Common Stock Purchase Agreement,
                           Appendix 5.1. If ABBOTT elects to make any such
                           purchase of SPECTRX Common Stock, then, as further
                           provided in Section 5.4(A) hereof, the credit against
                           royalties for certain Milestone payments shall be
                           reduced by a sum equal to the aggregate purchase
                           price of such SPECTRX Common Stock.

                  (D)      If a Milestone payment is made as specified in 5.1(A)
                           or as a prepayment for an extension (Sections 3.4(B),
                           3.7(B), 3.7(C)) any such payment is non-refundable,
                           except as to credits in Section 5.4, or in any case,
                           if this Agreement is terminated.

         5.2 Transfer Price - (*)s for Continuous Product. If SPECTRX is
competitive with regard to Manufacturing Costs (*) greater than those by
bonafide Third Party manufacturers) unless SPECTRX adjusts its Transfer Price to
an amount equal to that Transfer Price that would have resulted had SPECTRX
Manufacturing Costs been no more than (*) greater, and manufacturing quality of
the (*)s for the Continuous Product (i.e., SPECTRX meets FDA QSR and European
EN46001 requirements, demonstrates to ABBOTT's reasonable satisfaction it has
sufficient manufacturing capacity to timely meet reasonably expected demand in
accordance with the forecast according to the Supply Agreement, and is able to
consistently supply (*)s that meet the final product specifications), then
ABBOTT and SPECTRX shall enter into a supply agreement substantially in the form
of Appendix 5.2 and containing the following terms for the supply of the (*)s by
SPECTRX to ABBOTT ("Supply Agreement"). ABBOTT shall pay a Transfer Price for
each (*) whether manufactured by SPECTRX or for SPECTRX by a Third Party that
equals the product of the Manufacturing Costs multiplied (*) or such lower
Transfer Price as SPECTRX may propose. If SPECTRX elects to supply the (*)s that
are manufactured by a Third Party under the direction of SPECTRX, ABBOTT shall
have the right to approve such Third Party, which approval will not be
unreasonably withheld.

         5.3 Royalty - Continuous Product. ABBOTT will pay royalties on annual
(*) of all Continuous Product and all (*) which are Licensed Products, excluding
that part of (*) attributable to (*) manufactured by SPECTRX, in the Territory
as set forth in Section 4.2(C) of the Agreement; subject to the (*) deduction in
Section 5.6, and provided, however, that the (*) of all Licensed Products shall
be aggregated to obtain the (*) Within One Year for purposes of the royalty
calculation set forth in Section 4.2(C) of the Agreement.

         5.4      Credits Against Royalties and Transfer Price.

                  (A)      The Milestone payments under Sections 5.1(A)(5) and
                           5.1(A)(6), up to a total amount of (*), less any
                           amounts paid for preferred

                           royalties payable by ABBOTT and/or the Transfer Price
                           of the (*)s purchased by ABBOTT from SPECTRX. Such
                           payments shall be credited against royalties or the
                           Transfer Price due to SPECTRX (1) at the time of
                           payment of such royalty so that SPECTRX shall receive
                           (*) of the royalty amount due to it (i.e., for every
                           (*) in royalties due SPECTRX, SPECTRX shall receive
                           (*) or (2) at a rate of (*) of the Transfer Price,
                           respectively, until the total of (*) or such
                           applicable lesser amount, has been credited against

                           Product establishes the First Shipment Date, and all

                           agreed to issue and sell, and ABBOTT has agreed to
                           purchase, an aggregate of 525,000 shares of a new
                           class of preferred stock of SPECTRX to be designated

                           stock received from ABBOTT, SPECTRX shall first use
                           the balance of those payments for the above-mentioned
                           continuing research and development activities and

                           Section 4.1 of this Third Amendment, which shall not
                           be before specifications sufficient to allow

                           offered by ABBOTT. During such negotiation, ABBOTT
                           shall supply (*) to SPECTRX on mutually agreeable
                           terms, or at SPECTRX's option, SPECTRX shall have the
                           right to purchase (*) from a Third Party.

                  (D)      In any case in which a license to patent rights
                           covering (*) Technology is conveyed to a party, it
                           shall convey a license to patent rights covering
                           combinations of (*) Technology with (*) Technology or
                           combinations of (*) Technology with (*), in which the
                           advancement over the art is in (*) Technology, and
                           the combination is made with (*) Technology or (*) in
                           existence as of the Effective Date of this Third
                           Amendment, but shall not convey a license to patent
                           rights covering (*) Technology or (*) alone.
                           Therefore, a license to such patent rights for the
                           combinations does not in and of itself provide the
                           right to practice the combination unless the party
                           already has the right to use such (*)Technology or
                           (*).

         6.2 (*). At SPECTRX's written request, ABBOTT agrees to enter into good
faith negotiations with SPECTRX for the granting of a license to SPECTRX for
ABBOTT Diagnostic Division (*) (which technology is not subject to an exclusive
license or other restrictions prohibiting the granting of a license at the time
of SPECTRX's request); provided, that, ABBOTT Diagnostics Division desires to
out-license such technology to Third Parties, not including technology which
ABBOTT is cross-licensing or has cross-licensed with a Third Party in order to
obtain the technology of such Third Party. If SPECTRX makes such a request to
ABBOTT and ABBOTT does not desire to out-license such technology at the time of
such request, then SPECTRX's request shall be effective for a (*) period
following the date the request is received by ABBOTT. If ABBOTT desires to
out-license such technology during such (*) period, ABBOTT will notify SPECTRX
and SPECTRX and ABBOTT will enter into good faith negotiations for the grant of
a license to SPECTRX for such technology. After such (*) period, ABBOTT will
have no obligation to enter into such negotiations unless SPECTRX makes another
request in writing. Any breach of this Section 6.2 by ABBOTT will not be
considered a material breach of the Agreement.

                           and neither party shall have an obligation under the
                           Agreement to grant such license to the other.

                  (B)      If under the terms of a contract that existed prior
                           to the Effective Date of the Agreement between a
                           party to this Agreement and a Third Party, such party
                           is obligated to license to such Third Party any
                           rights granted to it under this Article 6, then such
                           license shall be granted to such Third Party only to
                           the extent of the license granted to such party
                           (i.e., such license to a Third Party must include all
                           limitations imposed on the original licensee
                           hereunder).

                                  Appendix 5.1
                         COMMON STOCK PURCHASE AGREEMENT

                  THIS AGREEMENT is made as of November November 30, 1999
between SpectRx, Inc., a Delaware corporation located at 6025A Unity Drive,
Norcross, Georgia 30071 ("SpectRx"), and Abbott Laboratories, an Illinois
corporation located at 100 Abbott Park Road, Abbott Park, Illinois 60064
("Abbott").

                                   WITNESSETH:

                  WHEREAS, contemporaneously with the execution and delivery of
this Agreement, the parties hereto have entered into a certain Amendment dated
of even date herewith to that certain Research & Development and License
Agreement between the parties dated October 10, 1996 (the "Development
Amendment");

                  WHEREAS, pursuant to Section 5.1(A)(2) and Section 5.1(A)(3)
of the Development Amendment, and subject to certain terms and conditions,
Purchaser has agreed to make certain milestone payments to SpectRx, each in the
amount of (*);

                  WHEREAS, the parties hereto have agreed that Abbott (*) and
receive in exchange therefor shares of common stock of SpectRx ("SpectRx Common
Stock"), and to accommodate these agreements and the purchase and sale of such
shares of SpectRx Common Stock, the parties have entered into this Common Stock
Purchase Agreement;

                  NOW, THEREFORE, in consideration of the premises and the
mutual promises and covenants set forth below, SpectRx and Abbott agree as
follows:

         1.       AGREEMENT AS TO PURCHASE AND SALE OF SPECTRX COMMON STOCK.
Abbott at its election by delivery of a written notice to SpectRx ("Common Stock
Election Notice"), may use a portion, up to one-half, of its payment obligations
under each of Section 5.1(A)(2) and Section 5.1(A)(3) of the Development
Amendment to purchase shares of common stock of SpectRx ("SpectRx Common
Stock"). The number of shares of SpectRx Common Stock to be issued and sold by
SpectRx, and purchased by Abbott, should Abbott make any of the elections
described in the preceding sentence, will equal the sum so elected by Abbott to
be applied to purchase SpectRx Common Stock, divided by the average closing
sales price of the SpectRx Common Stock as reported by NASDAQ for the thirty
(30) trading days prior to the date of the Common Stock Election Notice. The
Common Stock Election Notice in respect of the payments due under Section
5.1(A)(2) and under Section 5.1(A)(3) shall be

issued and delivered simultaneously with the respective notifications pursuant
to such Section 5.1(A)(2) and Section 5.1(A)(3) made by Abbott of achievement of
such milestones. If Abbott elects to make any such purchase of SpectRx Common
Stock, then as further provided in Section 5.4(A) of the Development Agreement,
the credit against royalties for certain milestone payments shall be reduced by
a sum equal to the aggregate purchase price of such SpectRx Common Stock.

                  2.       CLOSING AND DELIVERIES. The closing of the purchase
and sale of SpectRx Common Stock pursuant to this Agreement shall be held at the
executive offices of SpectRx on the fifth (5th) business day following the date
of receipt by SpectRx of the Common Stock Election Notice, or at such other time
and place upon which SpectRx and Abbott shall agree. At such closing, SpectRx
will deliver to Abbott a certificate, registered in Abbott's name, representing
the shares of SpectRx Common Stock to be purchased, against payment of the sum
as to which Abbott has made an election to receive and purchase SpectRx Common
Stock as provided for hereinabove.

                  3.       REPRESENTATIONS AND WARRANTIES. Coincident with the
closing of the purchase and sale of SpectRx Common Stock pursuant to this
Agreement, SpectRx will deliver a certificate by which it will make to Abbott
representations and warranties that are substantially similar to those contained
in the Redeemable Convertible Preferred Stock Purchase Agreement of even date
herewith between the parties ("Preferred Stock Agreement"), although such
representations and warranties shall be updated or exceptions made thereto to
account for changes or events that have occurred between the date of this
Agreement and the date of such closing, and such other corresponding changes to
dates and references to financial statements and share numbers and the like so
as to enable SpectRx to make such representations on a current basis. Similarly,
Abbott will deliver a certificate at closing where it will make to SpectRx as of
the date of such closing the representations and warranties contained in Section
4 of the Preferred Stock Agreement.

                  4.       COVENANT RE: TRANSFER OF SPECTRX COMMON STOCK. Abbott
covenants and agrees that it shall not sell, make any short sale of, loan, grant
any option for the purchase of, or otherwise dispose of any shares of SpectRx
Common Stock acquired by Abbott pursuant to this Agreement for a period of one
hundred eighty (180) days from the date of issuance of shares of SpectRx Common
Stock. Abbott agrees that the certificates for shares of SpectRx Common Stock
issued pursuant to this Agreement shall bear the following legend:

         "THESE SECURITIES MAY NOT BE SOLD, PLEDGED OR OTHERWISE DISPOSED OF
         PRIOR TO ____________________ [181st day after issuance] BY REASON OF
         AN AGREEMENT BETWEEN THE COMPANY AND THE HOLDER OF THE SHARES
         REPRESENTED BY THIS CERTIFICATE."

                           (*) Supply Agreement Terms

Unless otherwise defined in this Exhibit 5.2, the defined terms have the
meanings set forth in the Third Amendment or the Agreement.

                  I. PRICING, ORDERING, DELIVERY, and INVOICING

A. Transfer Price. The Transfer Price for (*)s supplied by SPECTRX to ABBOTT

Costs. A reconciliation process will be developed as part of the Supply
Agreement to reconcile any differences between actual and estimated
Manufacturing Costs.

B. Manufacturing Costs Reduction. SPECTRX will use commercially reasonable
efforts to minimize Manufacturing Costs. If the then current Transfer Price for
(*)s results in a gross margin for SPECTRX of less than (*) any cost savings
will be absorbed by SPECTRX until said margin reaches (*). Gross margin shall be
computed as the difference between the Transfer Price and actual Manufacturing
Costs divided by the Transfer Price. SPECTRX will implement commercially
reasonable manufacturing process changes requested by ABBOTT. Any costs
associated with said changes will be paid (*). SPECTRX will buy raw materials
and components of the (*) through ABBOTT if ABBOTT can purchase such raw
materials and components at a lower price than SPECTRX.

C. Delivery. SPECTRX will ship within (*) from date of receipt of purchase order
if requested by ABBOTT as long as the cumulative quantities of (*)s ordered by
ABBOTT and scheduled to ship during that month do not exceed the forecast for
that month or SPECTRX's production capacity as defined in Section II-G. SPECTRX
will make commercially reasonable efforts to ship (*)s that are ordered in
excess of the amount forecasted for that month within thirty (30) days of
receipt of said order. ABBOTT will reimburse SPECTRX, with prior written
approval by ABBOTT, for any (*). SPECTRX shall ship (*)s ordered by ABBOTT
F.O.B. SPECTRX's manufacturing facility.

D. Forecasting and Ordering. ABBOTT shall provide rolling 12-month forecasts of
its monthly requirements starting six (6) months prior to the delivery of the
first production units, and, updated monthly for the first year after the first
(*) shipment, and quarterly thereafter, submitted thirty (30) days in advance of
the beginning of said quarter. The first three (3) months of such forecast shall
be binding and shall vary by no more than

(9) months of the forecast shall not be binding and shall be used only for
planning purposes and ordering materials.

E. Purchase Orders. Orders shall be placed upon ABBOTT's purchase order form,
specifying quantities ordered and delivery dates. Purchase orders must be placed

Purchase orders issued by ABBOTT are non-cancellable.

F. Invoice Terms. SPECTRX shall invoice ABBOTT for (*)s purchased by ABBOTT upon
shipment of such (*)s to ABBOTT. Such invoices shall be paid in full within
thirty (30) days of the date such invoice is received by ABBOTT.

G. Certificate of Analysis. Each shipment of (*)s will be delivered with a full
certificate of analysis verifying the (*)s' compliance with the current (*)
Specifications (as defined in Section II-A).

H. (*). At SPECTRX's option, ABBOTT will pay SPECTRX in advance for (*).

I. Tooling & Equipment. All tooling and equipment required to be purchased
exclusively for the manufacture of (*)s for ABBOTT will be paid for and owned by
ABBOTT, including any such tooling and equipment required to increase capacity.
ABBOTT shall bear all costs for replacement of such tooling and equipment owned
byAbbott, except in cases of negligence or willful misconduct on the behalf of
Spectrx in which case SPECTX shall bear all such costs.

J. ABBOTT Purchases. Any tooling, equipment, raw materials, and components that
are purchased by ABBOTT for use in manufacturing by SPECTRX and not then sold to
SPECTRX will not be included in calculating Manufacturing Costs for purposes of
determining the Transfer Price.

K. (*) Acceptance. ABBOTT shall have twenty (20) business days from date of

                      II. SPECIFICATIONS AND MANUFACTURING

A. Specifications. The specifications for the (*)(s) will be incorporated into
the Supply Agreement and shall include SpectRx's internal manufacturing
specifications as well as technical specifications and test protocols relating
to the (*)s ("(*) Specifications").

B. Regulatory & QSR Compliance. (*)s manufactured by SPECTRX for ABBOTT under
the Supply Agreement shall be manufactured and tested by SPECTRX in accordance
with the (*) Specifications, United States FDA QSR, European EN46001, and all
applicable federal, state and local laws, regulations and guidelines. Any fees
and expenses for licensing or registration to market the (*) in the U.S. and in
world markets shall be (*).

C. Safety Stock. At ABBOTT's request, SPECTRX shall maintain and store a safety
stock of key raw materials and (*) components sufficient to produce that
quantity of (*)s in ABBOTT's (*) forecast. In order to minimize the cost of
maintaining safety stock, SPECTRX will be allowed a reasonable amount of time to
adjust its safety stock as new forecasts are issued by ABBOTT in accordance with
Section I-D or as requested in writing by ABBOTT. (*).

D. Termination. In the event of termination of the Supply Agreement, ABBOTT will

E. Manufacturing Changes. SPECTRX and ABBOTT shall establish a "Change
Notification Protocol" covering changes in the manufacturing process of (*)s,
including but not limited to any changes that affect written quality plans for
production or written quality procedures respecting same, as well as any changes
outside the validated level or procedure, in manufacturing procedures, component
part or raw materials vendors or manufacturing sites. ABBOTT will have final
approval of such Change Notification Protocol. Under the Change Notification
Protocol, manufacturing changes will be classified, as determined by ABBOTT,
into three categories: 1) ABBOTT written approval required prior to
implementation, 2) SPECTRX notification to ABBOTT prior to implementation, and
3) no notification required. For those changes requiring approval by ABBOTT,
only upon notice of written approval from ABBOTT may SPECTRX incorporate such
change into the manufacturing process (such approval shall not be unreasonably
withheld and, if forthcoming, shall be delivered in a timely manner). All
changes to the design and manufacturing process will be made in accordance with
SPECTRX's written change control procedures incorporated into the Change
Notification Protocol, and in compliance with 21 CFR ss. 820.40. In the event
such manufacturing change was due to SPECTRX and it has an impact on product

registrations, SPECTX shall reimburse ABBOTT for the costs of any such product
registration amendment, notification or resubmission as a result of such
manufacturing change. In the event such manufacturing change was due to ABBOTT
and it has an impact on product registrations, ABBOTT shall pay for the costs of
any such product registration amendment, notification or resubmission as a
result of such manufacturing change. Abbott shall be responsible for the cost of
any inventory obsoleted by design or process changes requested by Abbott.

F. Manufacturing Site. Abbott shall have approval of SPECTRX's choice of
manufacturing site and any future changes, which approval shall not be
unreasonably withheld. In the event SPECTRX changes the manufacturing site for
reasons other than force majeure and such relocation has an impact on product
registrations, SPECTRX shall reimburse ABBOTT for the costs of any such product
registration amendment, notification or resubmission.

G. Manufacturing Capacity. SPECTRX shall maintain manufacturing capacity
(facilities, support personnel, equipment and tooling) of at least (*) above the
(*) forecast provided by ABBOTT.

H. Failure to Supply. Failure by SPECTRX to deliver by the requested delivery
date (*), will constitute a "Failure to Supply," unless such failure is due to
changes in design or process required by Abbott or due to ABBOTT's failure to
timely approve requested changes to the design and manufacturing process
requested by SPECTRX as described in Section II-E. Upon written notification by
ABBOTT of Failure to Supply, Abbott may (i) agree to a future delivery date,
(ii) terminate the Supply Agreement or (iii) require SPECTRX to assist ABBOTT,
and at ABBOTT's sole discretion, to allow ABBOTT to manufacture (*)s itself or
by a designated Third Party by transferring all know-how, technology, trade
secrets and patent rights necessary to manufacture (*)s ("(*) Technology")
thereby enabling ABBOTT to manufacture (*)s. To the extent required beyond
ABBOTT's licenses set forth in the Agreement to implement ABBOTT's right to
manufacture and sell such (*)s, SPECTRX hereby grants to ABBOTT, without the
necessity of any further documentation, a non-exclusive, royalty-free,
irrevocable worldwide manufacturing license. The license will include access to
SPECTRX's (*) Technology to make and have made such (*)s. In the event any (*)
Technology is owned by, controlled by or licensed from a Third Party, to the
extent required to implement ABBOTT's right to manufacture (*)s, SPECTRX shall
use commercially reasonable efforts to obtain from the owners, the right for
ABBOTT to use said (*) Technology for the production of (*)s. In addition,
SPECTRX shall reasonably assist ABBOTT in the transfer and the start-up of
manufacturing operations for such (*)s and shall make the necessary plans,
formulations and manufacturing processes and

its regulatory files and shall supply technical or regulatory assistance as is
reasonably requested by ABBOTT. Any tooling, equipment and component parts owned
or committed to be purchased by SPECTRX exclusively for the manufacture of the
(*)s will be sold to ABBOTT at SPECTRX's asset value for equipment and (*) for
raw materials and WIP. Within thirty (30) days of the first anniversary of
ABBOTT's shipment of (*)s manufactured by Abbott, if SPECTRX can demonstrate in
reasonable detail, its ability to resume manufacturing of the (*)s in accordance
with the Supply Agreement, SPECTRX may resume manufacturing within a mutually
agreed to time frame, with tooling, equipment and component parts sold back to
SPECTRX and reasonable assistance provided by ABBOTT. ABBOTT will not
unreasonably deny SPECTRX the right to resume manufacturing.

I. Warranty. SpectRx will warrant the (*)s for the same period of time ABBOTT
warrants the (*)s to its customers up to (*) from date of delivery to ABBOTT's
customers or (*) from delivery to ABBOTT, whichever comes first, for failure to
meet the (*) Specifications or SPECTRX's internal manufacturing specifications
due to defects in material (other than design) or workmanship, and will replace,
free of charge, any (*) component (*), that fails such warranty. Any spare parts
and shipping expenses associated with warranty work will be at SPECTRX's
expense. Abbott will return all (*)s to SpectRx which it wants replaced under
warranty, within thirty (30) days of return by customer and no later than thirty
(30) days after expiration of warranty. (*)

                             III. REGULATORY MATTERS

A. (*) Recalls. Should either party's actions or any governmental action
attributable to a (*) require: (a) the recall, destruction or withholding from
market of any Product sold by ABBOTT ("Recall") or (b) institution of a field
correction of any Product containing a (*) sold by ABBOTT ("Field Correction"),
SPECTRX shall bear the costs and expenses of such Recall or Field Correction to
the extent such Recall or Field Correction is attributable to SPECTRX's
manufacture of the (*)s, and ABBOTT shall bear the costs and expenses of such
Recall or Field Correction to the extent such Recall or Field Correction is not
attributable to SPECTRX's manufacture of the (*)s. Such Recall or Field
Correction shall be based solely on ABBOTT's policies and historical practices.

B. Site Inspections. SPECTRX shall allow representatives of ABBOTT to tour and
inspect all facilities utilized by SPECTRX in manufacturing, testing, packaging
and shipment of (*)s sold to ABBOTT under the Supply Agreement. During such
visits (and other reasonable times), SPECTRX shall provide reasonable access to
its manufacturing quality control documentation and shall cooperate with such

representatives in every reasonable manner. Except in extreme circumstances,
ABBOTT will provide a minimum of five (5) business days notice of any such
inspections. All such inspections shall be arranged by SpectRx, conducted during
SPECTRX's normal business hours and in the presence of a representative of
SpectRx.

C. Customer Complaints. In the event that ABBOTT or SPECTRX receives any
customer complaint regarding ABBOTT's Products containing SPECTRX (*)s, the
complaint shall be evaluated and investigated by ABBOTT. If ABBOTT determines
that the complaint is related to SPECTRX's (*), then SPECTRX shall assist ABBOTT
in follow-up correction of Product complaints, at ABBOTT's reasonable request,
should said complaint be the result of the (*).

                            IV. TERM AND TERMINATION

A. Term. The Supply Agreement shall become effective upon full execution of the
Supply Agreement and, unless terminated early in accordance with the terms of

                  Products pursuant to the Agreement.
         2.       If either party is in default of any material obligation
                  imposed upon such party under the Supply Agreement, such party
                  shall use reasonable efforts to remedy such default as soon as
                  possible, and if such default is not remedied within a period
                  of sixty (60) days after written notice thereof is given to
                  the defaulting party by the other party, then the other party
                  may terminate the Supply Agreement immediately by giving
                  written notice of termination to the defaulting party.
         3.       If SPECTRX is not cost competitive or does not elect to change
                  the Transfer Price, as set forth in Section 5.2 of the Third
                  Amendment, which determination may be made at the end of each
                  contract year of the Supply Agreement. Contract year shall

The Company represents and warrants to the Purchaser as follows:

Company has requisite power and authority to own and operate its properties and
assets, and to carry on its business as presently conducted and as proposed to
be conducted. The Company is not presently qualified to do business as a foreign
corporation in any jurisdiction other than Georgia, and the failure to be so

now conducted or as now proposed to be conducted.

         3.2      CORPORATE POWER. The Company has all requisite legal and
corporate power and authority to execute and deliver this Agreement and at the
First Closing to execute and deliver the agreements set forth as Exhibits hereto
(collectively referred to with this Agreement as the "Agreements"), and at each

to be issued and sold at such respective closings, to issue the Common Stock
issuable upon conversion of the Preferred Shares and to carry out and perform
its obligations under the terms of the Agreements.

         3.3      SUBSIDIARIES. The Company has no subsidiaries or affiliated
companies and does not otherwise own or control, directly or indirectly, any

consists or will, upon the filing of the Certificate of Designations, consist of
50,000,000 shares of Common Stock, and 5,000,000 shares of Preferred Stock, of
which 525,000 shall be designated as Redeemable Convertible Preferred Stock
pursuant to the Certificate of Designations (the "Preferred Stock"). As of
November 29, 1999, there are 8,048,856 shares of Common Stock, issued and
outstanding and no other shares of capital stock which are issued and
outstanding. As of November 29, 1999, there are options outstanding issued by
the Company to purchase an aggregate of 1,121,789 shares of Common Stock. All of
the outstanding shares of Common Stock are duly authorized, validly issued,
fully paid and nonassessable, and were issued in compliance with applicable
federal and state securities laws. The Preferred Shares, when issued pursuant to
the terms of this Agreement, will be duly authorized, validly issued, fully


                                       2

paid and nonassessable. The Company has reserved 559,225 shares of Common Stock
for issuance upon conversion of the Preferred Stock, and 1,303,112 shares of its
Common Stock for issuance pursuant to its stock option plans. Except as set

         3.5      AUTHORIZATION. All corporate action on the part of the
Company, its officers, directors and stockholders necessary for the
authorization, execution, delivery and performance of the Agreements by the
Company, the authorization, sale, issuance and delivery of the Preferred Shares
(and the Common Stock issuable upon conversion of the Preferred Stock) and the
performance of all of the Company's obligations under the Agreements has been
taken or will be taken prior to the Closing. The approval of the transactions
provided for herein will constitute approval of Abbott becoming an interested
stockholder under Section 203 of the Delaware General Corporation Law, to the
extent applicable. The Agreements, when executed and delivered by the Company,
shall constitute valid and binding obligations of the Company, enforceable in
accordance with their terms, and subject to the laws of general application
relating to bankruptcy, insolvency and the relief of debtors and rules of law
governing specific performance, injunctive relief or other equitable remedies.
The Preferred Shares, when issued in compliance with the provisions of this
Agreement, will be validly issued, will be fully paid and nonassessable, and
will have the rights, preferences and privileges described in the Certificate of
Designations; the Common Stock issuable upon conversion of the Preferred Stock
has been duly and validly reserved and, when issued in compliance with the
provisions of this Agreement and the Certificate of Designations, will be
validly issued, and will be fully paid and nonassessable; and the Preferred
Stock and such Common stock will be free of any liens or encumbrances, assuming
the Purchaser takes the Preferred Shares with no notice thereof, other than any
liens or encumbrances created by or imposed upon the holders; provided, however,
that the Preferred Stock (and the Common Stock issuable upon conversion thereof)
may be subject to restrictions on transfer under state and/or federal securities
laws as set forth herein.

         3.6      REPORTS AND FINANCIAL STATEMENTS. The Company has delivered to
the Purchaser prior to the execution of this Agreement a copy of each

10-Q for the quarters ended March 31, 1999 and June 30, 1999, the definitive
proxy statement for the Company's 1999 annual meeting of shareholders and any
Current Reports on Form 8-K (as such documents have since the time of their

Securities Exchange Act of 1934, as amended and (b) did not contain any untrue
statement of a material fact or omit to state a material fact required


                                       3
<PAGE>   56

to be stated therein or necessary in order to make the statements therein, in

                                    SECTION 4

                 REPRESENTATIONS AND WARRANTIES OF THE PURCHASER

         The Purchaser represents and warrants to the Company with respect to
the purchase of the Preferred Shares as follows:

         4.1      EXPERIENCE. It has substantial experience in evaluating and
investing in private placement transactions of securities in companies similar
to the Company so that it is capable of evaluating the merits and risks of its
investment in the Company and has the capacity to protect its own interests.

         4.2      INVESTMENT. It is acquiring the Preferred Shares and the
Common Stock underlying the Preferred Stock for investment for its own account,
not as a nominee or agent, and not with the view to, or for resale in connection
with, any distribution thereof. It understands that the Preferred Shares to be
purchased and the Common Stock underlying the Preferred Stock have not been, and
will not be, registered under the Securities Act of 1933, as amended (the
"Securities Act") by reason of a specific exemption from the registration
provisions of the Securities Act, the availability of which depends upon, among
other things, the bona fide nature of the investment intent and the accuracy of
such Purchaser's representations as expressed herein.

         4.3      RULE 144. It acknowledges that the Preferred Stock and the
underlying Common Stock must be held indefinitely unless subsequently registered
under the Securities Act or unless an exemption from such registration is
available. It is aware of the provisions of Rule 144 promulgated under the
Securities Act which permit limited resale of shares purchased in a private
placement subject to the satisfaction of certain conditions, including, among
other things, the existence of a public market for the shares, the availability
of certain current public information about the Company, the resale occurring
not less than one year after a party has purchased and paid for the security to
be sold, the sale being effected through a "broker's transaction" or in


                                       4
<PAGE>   57

transaction directly with a "market maker" and the number of shares being sold
during any three-month period not exceeding specified limitations.

         4.4      NO PUBLIC MARKET. It understands that no public market now
exists for the Preferred Shares and that the Company has made no assurances that
such a public market will ever exist.

         4.5      ACCESS TO DATA. It has had an opportunity to discuss the
Company's business, management and financial affairs with its management. It has
also had an opportunity to ask questions of officers of the Company, which
questions were answered to its satisfaction. It understands that such
discussions, as well as any written information issued by the Company, were
intended to describe certain aspects of the Company's business and prospects but
were not a thorough or exhaustive description.

         4.6      AUTHORIZATION. This Agreement when executed and delivered by
such Purchaser will constitute a valid and legally binding obligation of the
Purchaser, enforceable in accordance with its terms, subject to laws of general
application relating to bankruptcy, insolvency and the relief of debtors and
rules of law governing specific performance, injunctive relief or other
equitable remedies.

         4.7      BROKERS OR FINDERS. The Company has not, and will not, incur,
directly or indirectly, as a result of any action taken by such Purchaser, any
liability for brokerage or finders' fees or agents' commissions or any similar
charges in connection with this Agreement.

         4.8      TAX LIABILITY. It has reviewed with its own tax advisors the
federal, state, local and foreign tax consequences of this investment and the
transactions contemplated by this Agreement. It relies solely on such advisors
and not on any statements or representations of the Company or any of its
agents. It understands that it (and not the Company) shall be responsible for
its own tax liability that may arise as a result of this investment or the
transactions contemplated by this Agreement.

         4.9      LEGEND. It is understood that the certificates evidencing the
Preferred Shares, and shares of Common Stock to be issued upon conversion of the
Preferred Shares, will bear the following legend: "THESE SECURITIES HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. THEY MAY NOT BE SOLD, OFFERED
FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN
EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF COUNSEL
SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED OR UNLESS
SOLD PURSUANT TO RULE 144 OF SUCH ACT."

                                   Schedule 1

                     DESIGNATIONS, PREFERENCES AND RIGHTS OF
                    REDEEMABLE CONVERTIBLE PREFERRED STOCK OF
                                  SPECTRX, INC.

         Pursuant to authority granted in the certificate of incorporation, as
amended, of SpectRx, Inc. (the "Corporation"), the Board of Directors of the
Corporation has been authorized to issue in series shares of preferred stock and
to designate by resolution the relative preferences and rights of each series
established. By resolution of the Corporation's Board of Directors, the
Corporation has established and fixed the relative preferences and rights of
525,000 shares of preferred stock designated the "Redeemable Convertible
Preferred Stock," each of $0.001 par value.

                  For the purposes of this statement,

                  "Board of Directors" shall mean the board of directors of the
Corporation.

                  "Common Stock" shall mean the common stock, $0.001 par value,
of the Corporation.

                  "Corporation" shall mean SpectRx, Inc.

                  "Holder" means a holder of record of shares of Preferred
Stock.

                  "Issue Date" as to any share of Preferred Stock shall mean the
date of issuance of such share.

                  "Invested Amount" per share of Preferred Stock shall mean
$10.00 (as adjusted for changes in the Preferred Stock by stock split, stock
dividend, or the like occurring after the Original Issue Date).

                  "Junior Stock" means shares of any class of capital stock of
the Corporation ranking subordinate to the Preferred Stock as to both dividends
and distribution of assets upon liquidation.

                  "Original Issue Date" shall mean the initial Issue Date, when
shares of Preferred Stock are first issued.

                  "Preferred Stock" shall mean the 525,000 shares of Redeemable
Convertible Preferred Stock, $0.001 par value, hereby designated.

                  The rights, preferences, privileges and restrictions granted
to and imposed upon the Preferred Stock are as follows:



                                       13
<PAGE>   66

                  (a)      Dividend Rights. The Holders shall be entitled when
and if declared by the Board of Directors to receive dividends out of assets of
the Corporation legally available therefor at an annual rate of $0.60 per share
of Preferred Stock (as adjusted for changes in the Preferred Stock by stock
split, stock dividend, or the like occurring after the Original Issue Date).
Such dividends shall be cumulative and shall accrue whether or not declared by
the Board of Directors of the Corporation. So long as any shares of Preferred
Stock shall be outstanding, the Corporation shall not declare or pay on any
Junior Stock any dividend whatsoever, whether in cash, property or otherwise,
nor shall the Corporation make any distribution on any Junior Stock, nor shall
any Junior Stock be purchased or redeemed by the Corporation, nor shall any
monies by paid or made available for a sinking fund for the purpose of
redemption of Junior Stock, unless all dividends declared or accrued on any
outstanding shares of Preferred Stock shall have been paid or declared and a sum
of money sufficient for the payment thereof set apart.

                  (b)      Liquidation. In the event of any voluntary or
involuntary liquidation, dissolution or winding up of the Corporation, before
any payment or distribution of the assets of the Corporation shall be made to or
set apart for the holders of Junior Stock, the Holders shall be entitled to
receive in respect of their shares of Preferred Stock payment out of assets of
the Corporation of Ten Dollars ($10.00) per share, plus all accrued but unpaid
dividends to the date of final distribution.

                  (c)      Conversion. The Holders shall have conversion rights
in respect of these shares of Preferred Stock as follows (the "Conversion
Rights"):

                           1.       Conversion Rate. The shares of Preferred
Stock shall be convertible, at the times and under the conditions described in
this Section (c) hereafter, at the rate (the "Conversion Rate") of one share of
Preferred Stock into the number of shares of Common Stock that equals the
quotient obtained by dividing the Invested Amount by the Conversion Price
(defined hereinafter). Thus, the number of shares of Common Stock to which a
Holder shall be entitled upon any conversion provided for in this Section (c)
shall be the product obtained by multiplying the Conversion Rate by the number
of shares of Preferred Stock being converted. Such conversion shall be deemed to
have been made on the Conversion Effective Date (defined hereinafter), and such
conversion shall be effected in accordance with the procedures described in
Subsection (c)(3) below. Upon conversion of any shares of Preferred Stock, the
Company shall pay all declared or accrued but unpaid dividends as to such shares
to the Holders thereof to and through the Conversion Effective Date; provided,
however, that the Corporation may, at its option, in lieu of making a full cash
payment of all such declared or accrued but unpaid dividends, make payment
thereof in that number of whole shares of Common Stock calculated by dividing
the total of such declared or accrued but unpaid dividends due such Holders by
the Conversion Price.. The "Conversion Price" shall be equal to the greater of
(I) (*) or (ii) the average of the closing sales price of the Common Stock as
reported by the NASDAQ Stock Market for each day of the thirty (30)-day trading
period that begins on the trading day that is




                                       14
<PAGE>   67

fifteen (15) trading days prior to the date of the receipt by the Corporation of
the Conversion Notice (defined hereinafter).

                           2.       Conversion Right. Each share of Preferred
Stock shall be convertible, at the option of the Holder thereof and without
payment of additional consideration, at any time after the first (1st)
anniversary of the Issue Date in respect of such share at the office of the
Corporation or any transfer agent for the Preferred Stock, into Common Stock at
the then effective Conversion Rate; provided, however, that if on or prior to
such first anniversary, the Corporation shall effect a merger or consolidation
wherein shares of Common Stock are exchanged for securities of another
corporation or for other consideration, then each of the Holders will be
afforded reasonable prior notice of such merger or consolidation and permitted,
if such Holder so chooses, to convert its shares of Preferred Stock into Common
Stock at the then effective Conversion Rate to be effective immediately prior to
the effectiveness of such merger or consolidation.

                           3.       Automatic Conversion. Each outstanding share
of Preferred Stock shall automatically be converted into Common Stock on and as
of December 31, 2004, at the then effective Conversion Rate. Such conversion
shall be automatic, without need for any further action by the Holders and
regardless of whether the certificates representing such shares are surrendered
to the Corporation or its transfer agent; provided, however, that the
Corporation shall not be obligated to issue certificates evidencing the shares
of Common Stock issuable upon such conversion or to pay the dividends payable
upon such conversion unless certificates evidencing such shares of the Preferred
Stock are surrendered to the Corporation in accordance with the procedures
described in Subsection (c)(5) below. Upon the conversion of the Preferred Stock
pursuant to this Subsection (c)(3), the Corporation shall promptly send notice
thereof to each Holder, which notice shall state that certificates evidencing
shares of Preferred Stock must be surrendered at the office of the Corporation
(or of its transfer agent for the Common Stock, if applicable) in the manner
described in Subsection (c)(5) below.

                           4.       Fractional Shares. No fractional shares of
Common Stock shall be issued upon conversion of Preferred Stock, and any shares
of Preferred Stock surrendered for conversion that would otherwise result in a
fractional share of Common Stock shall be redeemed at the then effective
Conversion Price per share, payable as promptly as possible when funds are
legally available therefor.

                           5.       Mechanics of Conversion. Before any Holder
shall be entitled to receive certificates representing the shares of Common
Stock into which shares of Preferred Stock are converted in accordance with
Subsections (c)(2) or (c)(3) above, such Holder shall surrender the certificate
or certificates for such shares of Preferred Stock, duly endorsed, at the office
of the Corporation or of any transfer agent for the Preferred Stock, and shall
give written notice to the Corporation at such office of the name or names in
which such Holder wishes the certificate or certificates for


                                       15
<PAGE>   68
shares of Common Stock to be issued, if different from the name shown on the
books and records of the Corporation. Said conversion notice ("Conversion
Notice") shall also contain such representations of the Holder as may reasonably
be required by the Corporation to the effect that the shares to be received upon
conversion are not being acquired and will not be transferred in any way that
might violate the then applicable securities laws. In the case of a conversion
pursuant to Subsection (c)(2) hereof, the Corporation shall, on the
seventy-fifth (75th) day succeeding receipt by the Corporation of the Conversion
Notice, unless the Corporation elects to redeem such shares of Preferred Stock
in accordance with the provisions of Subsection (d)(2) hereof, issue and deliver
at such office to such Holder, or to the nominee or nominees of such Holder as
provided in the Conversion Notice, a certificate or certificates for the number
of shares of Common Stock to which such Holder shall be entitled as aforesaid.
Such date for issuance and delivery of the shares of Common Stock received upon
conversion of Preferred Stock pursuant to Subsection (c)(2) hereof is hereafter
referred to as the Conversion Effective Date. The person or persons entitled to
receive the shares of Common Stock issuable upon a conversion pursuant to
Subsection (c)(2) hereof shall be treated for all purposes as the record holder
or holders of such shares of Common Stock as of the Conversion Effective Date.
All certificates issued upon the exercise or occurrence of the conversion shall
contain a legend governing restrictions upon such shares imposed by law or
agreement of the Holder or his or its predecessors.

                           6.       Adjustment for Subdivisions or Combinations
of Common Stock. In the event the Corporation at any time or from time to time
after the Original Issue Date effects a subdivision or combination of the
outstanding Common Stock into a greater or lesser number of shares without a
proportionate and corresponding subdivision or combination of the outstanding
Preferred Stock, then and in each such event the Conversion Price (and the
corresponding Conversion Rate) shall be increased or decreased proportionately.

                           7.       No Impairment. The Corporation shall not, by
amendment of its Certificate of Incorporation or Bylaws or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Corporation, but shall at all times in good faith assist in the
carrying out of all the provisions of this Section (c) and in the taking of all
such action as may be necessary or appropriate in order to protect the
Conversion Rights of the Holders against impairment.

                           8.       Reservation of Stock Issuable Upon
Conversion. The Corporation shall at all times reserve and keep available out of
its authorized but unissued shares of Common Stock solely for the purpose of
effecting the conversion of the shares of the Preferred Stock such number of its
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of all outstanding shares of the Preferred Stock; and if at any time
the number of authorized but unissued shares of


                                       16
<PAGE>   69

Common Stock shall be insufficient to effect the conversion of all then
outstanding shares of the Preferred Stock, the Corporation shall take such
corporate action as may, in the opinion of its counsel, be necessary to increase
its authorized but unissued shares of Common Stock to such number of shares as
shall be sufficient for such purpose.

                           (d)      Redemption. The Preferred Stock shall be
subject to redemption as follows:

                                    1.       Optional Redemption at Election of
Holders. In the event the Holders elect, by a vote of the Holders of a majority
of the issued and outstanding shares of Preferred Stock, to cause the redemption
of the outstanding shares of Preferred Stock, then such Holders shall so notify
the Corporation by delivery of a written notice to the Corporation on or prior
to the later to occur of (i) September 30, 2002 or (ii) sixty (60) days
subsequent to the date upon which the Company gives the Holders notice (which
notice the Company undertakes to timely issue) of its right to cause such
redemption (which notice may not be given prior to June 1, 2002). Should such
election be timely made, then all shares of Preferred Stock shall be redeemed in
accordance with the following provisions of this Subsection (d)(1). The
Corporation shall, on December 31, 2002, redeem one-half (1/2) of all of the
then outstanding shares of Preferred Stock held by each Holder of Preferred
Stock at a price per share equal to the Redemption Price (hereinafter defined).
If the Corporation has achieved the Revenue Threshold (defined hereinafter),
then the Corporation shall, as soon as reasonably practicable after the
determination of whether the Corporation has met the Revenue Threshold, but in
any event on or prior to January 31, 2004, redeem all of the then outstanding
shares of Preferred Stock at a price per share equal to the Redemption Price. If
the Corporation has not achieved the Revenue Threshold, it shall, no later than
the time for redemption indicated in the immediately prior sentence, redeem
one-half (1/2) of the then outstanding shares of Preferred Stock held by each
Holder of Preferred Stock at a price per share equal to the Redemption Price,
and it shall, on December 31, 2004, redeem all of the then remaining outstanding
shares of Preferred Stock at a price per share equal to the Redemption Price.
Notwithstanding the foregoing, the date for notification of the election of the
Holders to cause a redemption as provided herein, and the dates for redemption
provided herein, may be extended by written agreement of the Corporation and the
Holders of a majority of the outstanding shares of Preferred Stock.

                                    2.       Optional Redemption Upon Conversion
Notice. In addition to the foregoing provisions governing mandatory redemption,
the Corporation may at its option redeem any shares of Preferred Stock which any
Holder has elected to convert to Common Stock by the issuance of a Conversion
Notice by redeeming any or all of such shares at a price per share equal to the
Redemption Price. If the Corporation elects to so redeem any such shares of
Preferred Stock, it shall, by the issuance of a notice to the Holders whose
shares are to be so redeemed, schedule a date for redemption, which date must be
prior to the Conversion Effective Date which would


                                       17
<PAGE>   70

apply to such shares in accordance with the provisions of Subsection (c)(4) were
they to be converted to Common Stock pursuant thereto. On or before each date
scheduled for redemption, each Holder of shares to be redeemed shall surrender
the certificate representing such shares to the Corporation and shall receive
payment of the Redemption Price therefor in cash. If fewer than all of the
shares represented by a surrendered certificate are redeemed, the Corporation
shall issue a new certificate representing the unredeemed shares.

                                    3.       Certain Definitions. As used
herein, "Redemption Price" means $10.00 per share on Preferred Stock (as
adjusted for changes in the Preferred Stock by stock split, stock dividend, or
the like occurring after the Original Issue Date), plus all accrued but unpaid
dividends in respect of such share of Preferred Stock. "Revenue Threshold" shall
mean the recognition of Twenty Million Dollars ($20,000,000) or more of revenue
by the Corporation on a consolidated basis as reflected on the regularly
prepared income statements of the Corporation for the twelve (12) months ended
December 31, 2003.

                  (e)      Voting Rights. Except as set forth in this Section
(e), the Holders shall have no voting rights in respect of the Preferred Stock
except that Holders shall have the right to vote on those matters which, under
the Delaware General Corporation Law, voting by classes of stock is required.

                  So long as any shares of Preferred Stock are outstanding, the
Corporation shall not, without the unanimous consent (given by vote in person or
by proxy at a meeting called for the purpose, or by written consent) of the
Holders of the shares of Preferred Stock then outstanding:

                           (i)      alter or change the annual dividend rate on
the Preferred Stock;

                           (ii)     alter or change the cumulative nature of the
annual dividend rate on the Preferred Stock or the date from which such
dividends are cumulative;

                           (iii)    alter or change the amounts which the
Holders shall be entitled to receive on the liquidation, dissolution or winding
up of the Corporation;

                           (iv)     alter or change the terms relating to time
of payment or price to be paid in connection with the redemption of Preferred
Stock by the Corporation;

                           (v)      alter or change the terms relating to
conversion of Preferred Stock to shares of Common Stock;

                           (vi)     allocate any earned surplus, whether now
existing or hereafter arising, to capital, in accordance with Delaware law, if
the effect thereof would


                                       18
<PAGE>   71
be to reduce the legally available funds for payment of dividends or for
redemption of the Preferred Stock; or

                           (vii)    create or authorize any shares of any class
of capital stock of the Corporation having any preference or priority as to
either dividends or distribution or assets upon liquidation superior to any such
preference or priority of the shares of Preferred stock or reclassify any
securities into shares of such superior stock.

                  (f)      Registration of Transfer. The Corporation shall keep
at its principal office (or such other place as the Corporation reasonably
designates) a register for the registration of Preferred Stock. Upon the
surrender of any certificate representing Preferred Stock at such place, the
Corporation shall, at the request of the record Holder of such certificate,
execute and deliver (at the Corporation's expense) a new certificate or
certificates in exchange therefor representing in the aggregate the number of
shares represented by the surrendered certificate, and the Corporation forthwith
shall cancel such surrendered certificate. Each such new certificate will be
registered in such name and shall represent such number of shares as is
requested by the Holder of the surrendered certificate and will be substantially
identical in form to the surrendered certificate, and dividends shall accrue on
the Preferred Stock represented by such new certificate from the date to which
dividends have been fully paid on such Preferred Stock represented by the
surrendered certificate. The issuance of new certificates shall be made without
charge to the Holders of the surrendered certificates.

                  (g)      Replacement. Upon receipt of evidence reasonably
satisfactory to the Corporation (an affidavit of the registered Holder shall be
satisfactory) of the ownership and the loss, theft, destruction or mutilation of
any certificate evidencing shares of Preferred Stock, and in the case of any
such loss, theft or destruction, upon receipt of indemnity reasonably
satisfactory to the Corporation (provided that if the Holder is a financial
institution, other institutional investor or executive officer of the
Corporation, such Holder's own agreement shall be satisfactory), or, in the case
of any such mutilation upon surrender of such certificate, the Corporation shall
(at its expense) execute and deliver in lieu of such certificate a new
certificate of like kind representing the number of shares represented by such
lost, stolen, destroyed or mutilated certificate and dated the date of such
lost, stolen, destroyed or mutilated certificate, and dividends shall accrue on
the Preferred Stock represented by such new certificate from the date to which
dividends have been fully paid on such lost, stolen, destroyed or mutilated
certificate.

                  (h)      Notices. Any notice required by the provisions hereof
to be given to the Corporation or Holders shall be deemed given if deposited in
the United States Postal Service, postage prepaid, and addressed to the
Corporation at its then principal executive office, or to each Holder at the
address of such Holder appearing on the books of the Corporation.
