                                     PART I

ITEM 1.   BUSINESS.

     Hologic, Inc. (the "Company") is a leading international developer,
manufacturer and marketer of X-ray bone densitometers which precisely measure
bone density for use in the diagnosis and monitoring of metabolic bone diseases
such as osteoporosis.  The Company pioneered the use of dual-energy X-ray
absorptiometry ("DXA") to measure bone density, introducing the first DXA bone
densitometer in 1987.  Since this introduction, DXA systems have become the
standard for measuring bone density.  In 1995, the Company introduced its fourth
generation of DXA bone densitometers, its clinically oriented QDR [registered
trademark] 4500 ACCLAIM product line.

     To address the growing clinical market for the early diagnosis and
monitoring of osteoporosis, the Company is developing products that it believes
will complement its DXA product line.  In December 1994, the Company acquired
the ultrasound bone analyzer business of Walker Sonix, Inc. ("Walker Sonix").
The Company is developing an enhanced ultrasound bone analyzer, the Sahara
[trademark] which it intends to introduce in clinical test sites in the United
States and certain international markets during fiscal 1996.  The Company
believes that ultrasound systems could represent a relatively low cost, compact,
easy-to-use, non-X-ray based, screening technique to assist in the initial
diagnosis of osteoporosis.  In September 1994, the Company began a joint
development effort with Serex, Inc. ("Serex") to develop a diagnostic strip test
to detect biochemical markers that indicate the rate of a patient's bone loss.
The strip test is being designed to provide a physician with a real-time means
of measuring a patient's biochemical response to osteoporosis therapies and
compliance with those therapies, as a complement to periodic bone density
measurements.  The Company and Serex have also recently entered into an
agreement in principle with a leading pharmaceutical company to develop and
market an over-the-counter version of the strip test.

BACKGROUND

     OSTEOPOROSIS.  Osteoporosis is a condition characterized by reduced bone
density that leads to an increased risk of fractures.  Bone is a dynamic organ
that is maintained through a process referred to as remodeling in which old bone
is removed (resorption) and new bone is formed.  In early adulthood, the levels
of bone resorption and bone formation are generally balanced, with the quantity
and distribution of bone throughout the body varying over time depending on
muscle mass, strength and use.  When remodeling does not function properly, and
resorption exceeds formation, the result is a net loss of bone mass and density,
often causing diminished structural integrity of the skeleton (particularly of
the trabecular "spongy" bone) and an increased risk of fracture.

     According to the National Osteoporosis Foundation (the "NOF"), 25 million
Americans, 80% of whom are women, and approximately 200 million people
worldwide, suffer from osteoporosis.  Osteoporosis typically develops silently
over a period of years, eventually progressing to a point where a fracture can
easily occur, causing pain and disability.  The post-menopausal female
population has the highest incidence of osteoporosis and the highest rate of
   
                                       2
<PAGE>
 
morbidity (loss of quality of life) and mortality due to osteoporosis.  The NOF
estimates that in the United States osteoporosis contributes to more than 1.3
million fractures annually, a majority of which were of the spine and hip, and
that related direct health care and indirect productivity costs in 1987 were
approximately $10 billion.  Hip fractures lead to the most serious consequences.
According to the NOF, as many as one in every five hip fracture patients dies
from complications within a year after fracture, one in every four requires
long-term care and an even higher percentage of hip fracture patients never
return to an active and independent lifestyle.

     Until recently, osteoporosis was thought to be an untreatable consequence
of aging.  The Company believes that the recent development and introduction of
new drug therapies, the aging of the population, and an increased focus on
women's health issues and preventive medical practices has created a growing
awareness among patients and physicians that osteoporosis is treatable.

     THERAPIES.  The Company believes that over 70 clinical studies are
currently in progress to assess the safety and effectiveness of new therapies to
treat osteoporosis. However, prior to 1995, there were only two approved drug
treatments for osteoporosis in the United States, hormone replacement therapy,
using estrogen and related hormones ("HRT"), and calcitonin, with the most
widely prescribed treatment being HRT.  Patient concerns regarding complications
related to prolonged use of HRT have contributed to a low compliance rate.
Until recently, calcitonin was available only in an injectable form, a delivery
method that has contributed to low patient compliance.  Although HRT and
calcitonin have generally been shown in clinical trials to slow or stop the loss
of bone mass, these therapies have not been proven to restore bone mass.

     On September 29, 1995, the FDA approved Merck's drug Fosamax for the
treatment of established osteoporosis in post-menopausal women.  Fosamax is a
bisphosphonate that acts by coating the bone surface and inhibiting bone
resorption.  Merck reports that in clinical studies of Fosamax conducted in over
16 countries post-menopausal patients with established osteoporosis who were
treated with Fosamax gained on average of 7-10% bone mass in the spine and 7-8%
bone mass in the hip over a three-year period compared to patients treated with
placebo, and that Fosamax reduced the number of new vertebral fractures
(fractures of the spine) by approximately 48% compared with placebo.  Merck is
conducting ongoing clinical trials to determine the effectiveness of Fosamax in
preventing osteoporosis. Fosamax is also approved in at least 18 countries in
addition to the United States.

     Other therapies cleared by the FDA to treat osteoporosis in 1995 are a
one-tablet hormone replacement therapy, which combines estrogen and progestin,
developed by Wyeth-Ayerst Laboratories, and an intra-nasal formulation of
calcitonin developed by Sandoz.  In addition, in November 1995, an FDA advisory
committee recommended that the FDA approve slow-release sodium fluoride for the
treatment of post-menopausal osteoporosis.   Additional therapies undergoing
clinical trials for the prevention or treatment of osteoporosis include
bisphosphonates being developed by Proctor & Gamble (Rasidronate), Boehringer-
Mannheim (Ibandronate) and Sanofi (Tiludronate), and estrogen analogues or anti-
estrogens being developed by Eli Lilly (Raloxifene) and Pfizer (Draloxifene).
   
                                       3
<PAGE>
 
     In several European countries, Japan and other international markets,
there has been an earlier availability and greater acceptance of osteoporosis
therapies.  Some of these therapies include estrogens, bisphosphonates,
calcitonins, vitamin D compounds and ipriflavone.

     The timing of when and where new drugs will become commercially available,
if ever, is uncertain.  However, the Company believes that there will be
broadened and new approvals of osteoporosis therapies for both treatment and
prevention which should positively impact the bone assessment market worldwide.

     Diagnosis and Monitoring of Osteoporosis.  There are a number of different
technologies that are available that can be used to assess bone mineral status.

     Since the introduction of the first DXA bone densitometer by the Company
in 1987, dual energy X-ray absorptiometry has become the primary means of
measuring bone density.  Prior to that introduction, the most widely used bone
density measuring technique for the hip and spine was dual photon absorptiometry
(DPA).  DPA systems were not very precise and required relatively long scanning
times and the use of an expensive radioactive source that required periodic
replacement.  In contrast, DXA systems have much higher precision, require
significantly shorter scanning times and do not require a radioactive source.
DXA systems require a low patient radiation exposure.  The most advanced DXA
systems can be used to measure the bone density of the whole body, or any site,
including the most important fracture sites of the hip or spine.  As a result of
their precision and versatility, DXA systems have become the predominant means
of evaluating low bone density before fractures occur and monitoring changes in
a patient's bone density in response to therapies.

     Other bone assessment technologies include single photon absorptiometry
(SPA), radiographic absorptiometry (RA), quantitative computed tomography (QCT),
quantitative ultrasound and biochemical markers.

     Single photon absorptiometry was introduced in the 1960s and represents an
effective method of measuring bone density at a peripheral site of the skeleton
(forearm or heel), although it cannot be used to measure the most important
fracture sites of the spine or hip. SPA systems also have the added
inconvenience of requiring the patient to place the site being scanned in water
or other tissue-equivalent media to achieve precision.  SPA, however, does
represent a relatively inexpensive and valuable tool in the diagnosis of
osteoporosis with reasonable precision and low radiation exposure.

     Quantitative computed tomography was introduced in the mid 1970s and can
measure bone density by using a CT scanner to determine both the patient's bone
density and bone distribution in three dimensions.  QCT, however, has remained
limited in clinical use because of its relatively high radiation dose and the
high cost of CT scanner equipment.

     Radiographic absorptiometry, also introduced in the 1970s, measures bone
density from two X-ray images (radiographs) of the hand placed alongside a
calibration device using a conventional X-ray machine.  The radiographs are 
   
                                       4
<PAGE>
 
sent to a central processing laboratory where a computer measures the density of
the bone. The precision of this technique is comparable to SPA measurements. An
advantage of this system is that it does not require any additional capital
investment, as traditional X-ray equipment can be used to obtain the
radiographs. The technique, however, cannot be used to measure and monitor the
hip or spine. Also, because the radiograph must be sent to a laboratory for
testing, it does not provide a real-time assessment of bone density, and, if the
test is positive, a follow-up consultation is required. The Company believes
that RA will be useful in rural areas where there may not be a sufficient
concentration of patients to justify a capital investment in DXA bone density
measuring equipment.

     Ultrasound has long been used in medical testing.  However, the use of
ultrasound for the detection of osteoporosis was not commercially introduced
until recently, and then only in certain foreign countries.  Ultrasound
measurement has concentrated mainly on the calcaneous (the heel), which is
comprised primarily of trabecular bone, as a measuring site.  Initial clinical
trials of ultrasound systems have indicated a significant association of low
ultrasonic bone measurements of the calcaneous and the risk of fracture.  The
latest developments in hardware and software, resulting in enhanced precision
and ease of use, are currently making ultrasound techniques an option for the
diagnosis of osteoporosis.  Major advantages of ultrasound examination are the
complete absence of radiation and the small size and low cost of the equipment.
Ultrasound devices do not use X-rays in making their measurements and therefore
do not require X-ray licensing or registered operators.  However, because
ultrasound bone measurements currently are not as precise as DXA and other
measurements, they are less reliable for continued monitoring of small changes
in bone density or for assessing the response to therapies.  In addition, they
are generally limited to measurements at peripheral sites, not the more
important spine or hip fracture sites.  Accordingly, the Company believes that
the most likely use for ultrasound techniques currently employed and under
development by the Company and others will be for initial screening for
osteoporosis and not for continued monitoring of changes in bone density or the
response to therapies.

     Biochemical markers are substances that are produced within the body that
correlate directly or indirectly to disease or bodily function.  A number of
biochemical markers have been discovered that can be used to measure the rate of
bone resorption or formation.  These measurements, while not measuring bone
density, can provide a means to assess quickly (within approximately three
months) the effectiveness of treatment and patient compliance with therapies for
osteoporosis. A baseline and subsequent bone density tests (as frequently as
annually) must be used in conjunction with biochemical marker measurements to
assess fully the bone density of the patient.  Because biochemical markers
cannot be used independently to diagnose osteoporosis or risk of fracture, or to
monitor a patient's changes in bone density as a result of therapy or otherwise,
the Company believes that biochemical marker tests, including those being
developed by the Company, will complement and not replace densitometry.

     MARKET. The Company believes that the clinical market for osteoporosis
diagnostic and monitoring products is expanding due to the recent development
and introduction of new drug therapies to treat osteoporosis, the more
widespread and increased reimbursement for bone density examinations, the 
    
                                       5
<PAGE>
 
aging of the population, and an increased focus on women's health issues and
preventive medical practices. All of these factors have led to an increased
awareness by women and primary care providers, such as gynecologists and family
physicians, that osteoporosis is a treatable disease and that measurement of
bone density is an integral component of diagnosis and monitoring of this
disease.

     Upon obtaining FDA approval for Fosamax in September 1995, Merck launched
an extensive educational campaign to increase patient and physician awareness
that osteoporosis is a treatable disease.  In connection with this effort, Merck
is promoting the use of DXA and other techniques to diagnose and monitor
osteoporosis and the effects of drug therapies.  The Company believes that this
comprehensive Merck program will further accelerate the growth of the bone
densitometer and related markets.  Currently, Fosamax is only approved for use
by patients with established osteoporosis.  However, Merck and other drug
companies are conducting ongoing clinical trials to establish the efficacy of
drug therapies to prevent osteoporosis in high risk patients.  Such approval
would increase the need for patient testing and monitoring at an earlier age,
before a patient is afflicted with osteoporosis.

     In the United States, the Health Care Finance Administration, which
establishes guidelines for the reimbursement of health care providers treating
Medicare and Medicaid patients, provided validation for DXA bone densitometry
examinations as a clinically useful procedure by recommending the reimbursement
for DXA bone evaluations at the rate of $68 per scan effective April 1994.
Effective January 1995, HCFA furthered the clinical use of DXA evaluations by
increasing the recommended reimbursement rate to $124.  In part as a result of
the reimbursement policy recommendations implemented by HCFA, bone density
examinations are paid for by many private third party insurers in the United
States.

     With the recent increase in reimbursement levels in the United States, and
the FDA approval of Fosamax and other drug therapies, the Company believes that
the United States market for bone densitometers and other methods of bone
mineral assessment will expand from the hospitals, large clinics, research
institutions and imaging and women's centers, to the larger potential market of
primary care providers, including gynecologists and family physicians.

     In several European countries, Japan and other international markets, there
has been a greater availability or acceptance of osteoporosis therapies and an
earlier adoption of reimbursement for bone densitometry exams.   Countries in
which reimbursement for the use of X-ray bone densitometers has been approved
include Belgium, Brazil, Canada, Germany, Greece, Japan, South Korea, Spain and
Switzerland.  In addition, the Japanese government has been actively supporting
an educational program to promote public awareness of osteoporosis as a
treatable disease.  In Latin American countries such as Argentina, Brazil and
Chile, and in Pacific Rim countries, such as Australia, The Peoples Republic of
China, South Korea and Taiwan, there is a growing use of osteoporosis therapies
and an expanding market for osteoporosis diagnostic and monitoring equipment.

HOLOGIC'S STRATEGY
   
                                       6
<PAGE>
 
     The Company's goal is (i) to become the leading fully-integrated supplier
of technologically advanced, innovative and clinically valuable diagnostic
systems and tests that address the growing market for osteoporosis prevention
and treatment, and (ii) to diversify into other medical device markets which it
believes will be complementary to its current business.  Key elements of this
strategy are as follows:

     MAINTAIN AND ENHANCE DXA TECHNOLOGICAL LEADERSHIP.  The Company has been a
pioneer in the development of DXA bone densitometers.  Since commercially
introducing the first DXA bone densitometer in 1987, the Company introduced a
bone densitometer capable of assessing the bone density of the entire body in
1989, introduced the first bone densitometer capable of taking supine lateral
measurements of the spine in 1991 and introduced its fourth generation
clinically-oriented QDR 4500 ACCLAIM series of bone densitometers in 1995.   The
ACCLAIM series integrates the Company's most advanced X-ray technology into a
compact package that facilitates installation in a standard examination room.
The Company believes that because of their technological features, its DXA
systems have been and continue to be the most widely used bone densitometers for
clinical studies involving the emerging drug therapies for osteoporosis.  The
Company intends to continue to enhance and expand upon its core technical
expertise to develop increasingly efficient and cost-effective DXA bone
densitometer solutions.

     EXPAND RANGE OF COMPLEMENTARY BONE DIAGNOSTIC AND MONITORING PRODUCTS.  The
Company believes that a significant market exists for relatively low-cost
products that assess bone density, employ technologies that do not use X-rays or
other ionizing radiation, and may be used in a doctor's office.  In order to
address this market, the Company is pursuing the development and acquisition of
products that use ultrasound and biochemical markers to assess bone mineral
status.  Recent milestones achieved by the Company in connection with this
pursuit include the following:

     . In December 1994, the Company acquired the Walker Sonix ultrasound bone
       analyzer business.

     . In September 1995, the Company introduced a prototype of the Sahara, an
       internally developed advanced ultrasound bone analyzer that does not
       require the use of water, at the American Society of Bone Mineral
       Research.

     . In September 1994, the Company began a joint development effort with
       Serex to develop a low-cost biochemical marker strip test.

     . In December 1995, the Company and Serex further entered into an
       agreement in principle with a major pharmaceutical company to develop an
       over-the-counter version of the biochemical marker strip test.

The Company believes that if it is able to develop these products successfully
it will be in a position to offer a full range of diagnostic and monitoring
products for the growing osteoporosis market.  The Company also plans to pursue
other product development and market opportunities in the area of bone
assessment that the Company identifies as promising.
   
                                       7
<PAGE>
 
     EXPAND UNITED STATES DISTRIBUTION.  The Company believes that the continued
development of its distribution network in the United States will be an
important factor in its continued success.  The Company has developed an
experienced 11 person direct sales force covering the United States and plans to
enhance further its distribution capabilities in the United States through a
combination of an expansion of its sales force and strategic alliances with
companies with established distribution channels in the various market segments
for the Company's products.

     CONTINUED INTERNATIONAL EXPANSION.  International sales have accounted for
approximately 75% of the Company's sales in fiscal 1995, with such sales being
made predominantly to countries in Western Europe and Japan.  In fiscal 1995,
the Company increased its efforts to expand its market penetration into new
markets in Latin America, including Argentina, Brazil and Chile, and along the
Pacific Rim, including Australia, The Peoples Republic of China, South Korea and
Taiwan.  The Company intends to continue to seek to expand sales in these and
other less-developed territories.

     DIVERSIFICATION INTO COMPLEMENTARY MARKETS.  The Company is seeking to
leverage its medical device development, manufacturing and distribution
expertise to expand, through acquisition or strategic alliances, into
complementary markets.  Such markets could include other diagnostic or imaging
markets, or other women's healthcare markets.

     There can be no assurance that the Company will be able to implement
successfully any of its strategies on a timely basis, if at all, or if
successfully implemented, that any of these strategies will enable the Company
to maintain or enhance its growth.

BONE ASSESSMENT PRODUCTS

     The Company's products include a family of DXA bone densitometers which are
used for the precise measurement of bone density to assist physicians in the
diagnosis and monitoring of metabolic bone diseases such as osteoporosis.  Since
commercially introducing the first DXA bone densitometer in 1987, the Company
introduced its first bone densitometer capable of assessing the bone density of
the entire body in 1989, introduced the first bone densitometer capable of
taking lateral measurements of the spine in 1991, and, in 1995, introduced its
new QDR 4500 ACCLAIM fourth generation series of bone densitometers, which
integrates the Company's most advanced X-ray technology into a compact package
that facilitates installation in a standard examination room.  The United States
list prices for the Company's DXA bone densitometers range from approximately
$55,000 to $165,000 per system.

     The Company believes that a significant market may exist for relatively
low-cost products that assess bone mineral status, employ technologies that do
not use ionizing radiation and may be used in a doctor's office.  In order to
address this market, the Company has acquired or is developing products that use
ultrasound or measure biochemical markers to assist in the assessment of bone
mineral status.

     QDR X-RAY BONE DENSITOMETERS.  Since the Company's first commercial
shipment of a DXA system in October 1987, the Company has sold more than 2,000
DXA systems.  The Company believes that its systems' performance advantages 
    
                                       8
<PAGE>
 
and their early adoption by leading clinical investigators have led to their
market acceptance. The Company's DXA systems have been purchased for multiple-
site studies sponsored by the pharmaceutical companies and by the United States
government for evaluation of the incidence and treatment of osteoporosis. In
addition, pharmaceutical companies have promoted the purchase of the systems for
use by physicians to assist in the diagnosis and treatment of osteoporosis.

     Advantages of the Company's DXA systems include high precision (consistency
from test to test), low patient radiation exposure equivalent to 1/10th of a
conventional chest X-ray, a relatively fast scanning time, low operating cost,
no radioactive source and the ability to measure bone density of the most
important fracture sites, the spine and hip.  Studies conducted by the Company
and independent investigators have demonstrated that the systems can detect a
change in spine bone density with a precision error of less than 1%.

     All the Company's DXA systems employ the Company's patented Automatic
Internal Reference System, which continuously calibrates each patient's bone
density measurement to a known standard.  This system virtually eliminates
errors that might result from manual calibration and saves operators the time-
consuming task of calibrating several times a day.  The system automatically
compensates for drift in the X-ray system, detectors or other electronic
components which ensures long-term measurement stability.

     Each of the Company's DXA systems contains an X-ray source mounted beneath
the patient, who is positioned lying on her back.  The X-ray source generates
alternating high and low energy pulses in a thin beam that passes through the
Company's patented Automatic Internal Reference System and then through the
patient to an X-ray detector mounted above the patient.  Controlled by a
computer, the X-ray source and detector are moved in tandem across the patient.
When the X-ray beam is detected, it contains information about the X-ray
absorbing characteristics of both the patient and the calibration materials in
the Automatic Internal Reference System at each of the two levels of radiation.
The system converts this information into a digital format which is processed
and analyzed by a computer and displayed on a high-resolution color monitor,
both of which are incorporated into the system.

     The Company has invested substantial resources in developing operating and
applications software for its systems.  The software includes calibration
software, automated scan and analysis programs for each scan site, a patient
data base manager that archives all raw data for later retrieval and analysis
and allows the operator to review the current image with an earlier image of the
same patient.

     Initial DXA systems developed by the Company employed a single narrow
pencil beam detected by one receptor.  In 1991, the Company introduced the first
bone densitometer employing a high density fan shaped X-ray beam that is
detected by an array of receptors.  This configuration enables the system to
obtain better quality images with improved spatial resolution, significantly
faster scanning time and higher patient throughput compared to single-beam
systems.  Moreover, for standard spine and hip scans, fan beam technology can
   
                                       9
<PAGE>
 
reduce scan time by a factor of more than 25 compared to older single-beam
scanning systems.

     The Company developed this fan beam technology to perform lateral (side-to-
side) scans of the lower spine, in addition to the posterior-anterior (back-to-
front) measurements performed by the Company's pencil beam systems.  The
earliest and most dramatic loss of bone density in the spine occurs primarily in
the spine's soft (trabecular) bone, which is positioned directly behind the hard
(cortical) bone when taking back-to-front measurements.  This results in bone
density measurements that average the density of the soft and hard bone and
tends to mask changes in the soft bone.  A lateral scan permits the imaging and
measurement of the spine's soft bone with only limited interference from hard
bone.  In addition, a lateral scan reduces the interference caused by abnormal
accumulation of bone and calcium deposits in and around the spine.

     Numerous scientific articles have established lateral bone densitometry,
using supine patient positioning, as a highly precise and more diagnostically
sensitive way to measure the spine than conventional posterior-anterior
examinations.  Lateral densitometry also eliminates scan artifacts such as
aortic calcification or degenerative disease of the spinal processes that can
distort conventional posterior-anterior measurements.

     In November 1994, the Company introduced the QDR 4500A ACCLAIM at the
annual meeting of the Radiological Society of North America and in January 1995
obtained FDA clearance to sell the system in the United States.  As of December
11, 1995, regulatory approval to sell the system in Japan was pending.  See
"Regulation."

     The Company's QDR 4500 ACCLAIM series of bone densitometers offers rapid
scanning and high resolution imaging using the latest available fan beam and
high density, solid-state multi-detector array technology. In addition, the QDR
4500 ACCLAIM series is built in modular configurations that allow customers to
add new features and capabilities, while protecting their investment in the
equipment and patient data.

     An important feature of the QDR 4500A and QDR 4500SL is their ability to
perform lateral (side-to-side) scans of the lower spine, without turning the
patient on her side, in addition to the posterior-anterior (back-to-front)
measurements.  The QDR 4500A and QDR 4500SL ACCLAIM are capable of producing
high quality images of the spine, lateral spine, hip and other skeletal sites.
The ACCLAIM's scan arm allows for multiple scan views without patient
repositioning.  The images produced can be combined with capabilities that
enable vertebral dimensions to be determined with a radiation dose approximately
ten to 100 times lower than that of conventional chest X-rays.  Using the QDR
4500A or the QDR 4500SL, high-quality lateral images of the entire spine can now
be obtained in as little as ten seconds.

     The ACCLAIM systems are designed to require less floor space than any other
bone densitometer capable of taking hip and spine measurements.  The special
tabletop design and motorized scanner C-arm allow the QDR 4500C and QDR 4500SL
to be installed in a standard 8ft x 8ft examination room (the QDR 4500W and QDR
4500A require an 8ft x 10ft room).  Installation requirements for any of the
ACCLAIM bone densitometers are minimal and normally do not 
   
                                       10
<PAGE>
 
require special electrical, structural or lead-shielding preparation. In
addition to their small size, the QDR 4500 series offers virtually silent
operation.

     The ACCLAIM series has replaced the Company's QDR 1500, QDR 2000 and QDR
2000plus products.  The Company has retained its QDR 1000plus system as a low-
price offering.  The QDR 1000plus employs the Company's older pencil beam
technology.  In the fourth quarter of fiscal 1995, the ACCLAIM series accounted
for approximately 70% of DXA sales.

     ULTRASOUND.  In December 1994, the Company acquired the ultrasound bone
analyzer business of Walker Sonix.  WalkerSonix had developed an ultrasound
product line to assess bone mineral status of the heel.  The location of the
heel facilitates easy coupling of the ultrasound transducers at a site with a
relatively low amount of overlying soft tissue.  The heel is also made up of
predominantly trabecular bone which tends to be more metabolically active.  The
Walker Sonix ultrasound devices measure two parameters, Broadbased Ultrasound
Attention (BUA) and Speed of Sound (SOS) through a water medium to characterize
bone mineral status.  The use of water as a medium, which is a characteristic of
other ultrasound bone analyzers, requires the patient to place her foot in
water.  The use of water requires cumbersome plumbing and cleaning mechanisms to
be incorporated in the system.

     The Company is developing internally an enhanced dry ultrasound bone
analyzer, called "Sahara" that will not require the use of water.  The Company
believes that this "dry" technology will offer further operator convenience by
the elimination of the water handling required between each patient.  The
elimination of the use of water has also enabled the Company to reduce the size
and weight of the device. In September 1995, the Company introduced a prototype
of the Sahara at the American Society of Bone Mineral Research and plans to
begin clinical trials of the Sahara in the United States and selected foreign
countries, and to commence international sales of the system in fiscal 1996.
Commercial introduction of the system in the United States is dependent upon FDA
approval.  The Company believes that this approval process may take as long as
two to three years.  There can be no assurance that the Company will be able to
obtain FDA approval for the Sahara on a timely basis, if at all.

     Recent studies have suggested that ultrasound provides good separation of
fracture populations from reference groups and suggests that this method is a
promising screening tool for evaluating a patient's fracture risk.  However,
ultrasound does not allow for direct assessment of important hip and spine
fracture sites, has undocumented ability to follow the effects of therapy and
has less precision (reproducibility of results) compared to DXA measurements.
Accordingly, the Company believes that ultrasound systems will be used
predominantly as a low cost initial screening or diagnostic tool and not as a
patient monitoring tool.

     BIOCHEMICAL MARKERS.   In September 1994, the Company  entered into a joint
development agreement with Serex to develop a simple strip test for use by
physicians to monitor the levels of a patient's biochemical markers that
indicate the rate of bone resorption.  In December 1995, the Company and Serex
expanded the scope of this development effort by entering into an agreement in
principle with a major pharmaceutical company to develop an over-the-counter
   
                                       11
<PAGE>
 
version of this strip test.  Although biochemical markers cannot measure bone
density, the Company believes that biochemical markers may be useful as a tool
to determine if therapy is effective.  This is accomplished by comparing the
baseline level of the marker with the value obtained from a serial measurement
performed only two or three months following the start of therapy.  This same
technique may be useful to evaluate patient compliance with a prescribed
therapy.

     Traditionally, biochemical markers of bone were performed using high
pressure liquid chromatography ("HPLC") methods conducted in a research
laboratory.  HPLC procedures are complex, labor intensive requiring a highly
trained technician, relatively slow, subject to high variability and expensive.
For these reasons, biochemical markers of bone using HPLC methods have not been
used for routine clinical testing.  Recently, several immunodiagnostic tests
that are antibody-based have been developed as biochemical markers of bone
remodeling.  Immunodiagnostic tests may be performed in a variety of technical
formats.  The format that has been introduced by several companies is the
microtitre plate system, which is used for many different types of in-vitro
diagnostic tests and is normally performed in a reference laboratory.

     Serex has developed a proprietary and patented technology that enables
complex immuno-chemistry assays to be performed in a strip test format that the
Company believes is well-suited for testing directly in the physician's office
or the home to provide a real-time assessment of bone resorption.  In September
1994, the Company purchased a minority interest in Serex and entered into a
license and supply agreement with Serex to develop a urine-based bone resorption
test deliverable in a diagnostic strip test format.  The Company believes that
other applications for biochemical markers of bone as well as new markers are
likely to be developed in the future, and under its agreement with Serex, the
Company retains the first right of negotiation to develop and license such
tests.  There can be no assurance that Serex will be able to develop effective
strip tests, either for physician or over-the-counter use, on a timely basis, if
at all, that once developed, any strip test will be approved or cleared for sale
in the United States or other jurisdictions, or that once cleared or approved
for sale any strip test will be commercially successful.

OTHER PRODUCTS; SCANORA

     In order to take advantage of its European sales force and associated
distribution capability, in May 1993, the Company entered into exclusive
distribution agreement with Soredex, S.A. ("Soredex"), a division of Orion
Corporation of Helsinki, Finland, to distribute Scanora, a specialized system
for taking X-ray images of the maxillo-facial anatomy (teeth, jaw and other
facial structures).

     The Scanora system supports more than 1,000 different image modes,
including pre-surgical planning of dental implants, reconstructive surgery and
temporal mandibular joint repair.  This system provides significantly improved
images of the maxillo-facial anatomy compared to other techniques available in
the market, such as panoramic X-rays or computed tomography.  Dental implant
procedures have experienced significant growth in Europe over the past five
years.
   
                                       12
<PAGE>
 
     Under the agreement, the Company is the exclusive distributor of Scanora
systems in Western Europe, the Middle East and Africa, excluding South Africa
and Namibia. In addition, the Company has non-exclusive distribution rights in
several Eastern European countries.  The agreement with Soredex provides for the
Company to purchase a minimum number of systems in each contract year.  In the
event that the Company does not achieve the minimum levels set forth under this
agreement, Soredex has the option to terminate the distribution agreement.   The
Company has met its minimum purchase requirements in each year of the contract.
The agreement expires in May 1996, subject to the rights of each party to pursue
an extension under conditions to be agreed upon at such time.  There can be no
assurance that the Company and Soredex will agree to an extension of the
distribution agreement on favorable terms, if at all.

CUSTOMERS

     The Company's DXA customers include many pharmaceutical companies active in
the field of bone mineral metabolism, such as Ciba-Geigy, Eli Lilly, Merck,
Pfizer, Proctor & Gamble, Rhone-Poulenc/Rorer, Sandoz, Sanofi Research and
SmithKline.  The Company believes that because of their technological features,
its DXA systems have been and continue to be the most widely used bone
densitometers for clinical studies involving the emerging drug therapies for
osteoporosis.  The Company has a group of eight employees who provide data
collection and quality assurance services to such customers.  Initial clinical
evaluation sites for the Company's DXA systems included leading medical and
research institutions, such as the Mayo Clinic, the Massachusetts General
Hospital and the University of California at San Francisco in the United States;
the University of Lyon and Guy's Hospital in Europe; and Kobe University in
Japan.  These institutions, along with many other leading medical institutions,
continue to be users of the Company's DXA systems.

     The clinical demand for the Company's DXA bone densitometers is growing as
a result of the increased worldwide focus on women's health problems and the
availability of new osteoporosis therapies entering the market.  More than 50%
of the Company's new sales of DXA systems have shifted to the clinical segment
of the market which includes radiologists, endocrinologists and rheumatologists.
The Company expects a further shift in the market for bone densitometers to
primary care physicians, including gynecologists and family physicians, in
response to the development of new drug therapies for osteoporosis and the
growing awareness of osteoporosis as a treatable disease.

     In fiscal 1995, the Company's sales to its Japanese distributor, Toyo
Medic, accounted for 20% of product sales.  The loss of Toyo Medic as a customer
of the Company or an adverse change in the relationship between the Company and
Toyo Medic could have a material adverse affect on the Company's business.

MARKETING AND SALES

     In the United States, the Company sells its DXA systems primarily through
its direct sales force.  As of November 30, 1995, the Company had approximately
11 employees engaged in sales in the United States.  In order to penetrate this
market more effectively, the Company has expanded its direct 
  
                                       13
<PAGE>
 
marketing activities, including additions to its sales force, and has
implemented various leasing programs, including a program with a third party
leasing company to make its QDR 4500C ACCLAIM system available to physicians on
a fee-per-scan basis. To meet the growing demand for its products, the Company
plans to enhance further its distribution capabilities in the United States
through a combination of an expansion of its sales force and strategic alliances
with companies with established distribution channels in the various market
segments for the Company's products.

     The Company sells its DXA and Scanora systems in international markets
through independent distributors, as well as a direct sales force in France, the
Benelux countries, Spain and Portugal.  As of November 30, 1995, the Company had
six employees engaged in sales in Europe.

     The Company distributes its products in Japan through Toyo Medic, which has
been the Company's exclusive distributor in Japan since April 1988.  The
agreement requires Toyo Medic to purchase certain minimum quantities and to
provide technical and warranty support to its customers.

     In certain other territories outside the United States, the Company sells
its DXA systems through independent distributors, all of whom offer technical
support.  Employees of these distributors and sales representatives have
undergone product and technical training related to the Company's products.  The
Company has increased its efforts to expand its market penetration into Latin
America, including Argentina, Brazil and Chile, and into Pacific Rim countries
other than Japan, including Australia, the Peoples Republic of China, South
Korea and Taiwan, by working with local sales representatives and distributors
or entering into strategic marketing alliances in those territories.  The
Company believes that with time, Eastern Europe may present a significant
opportunity for growth and also is seeking to expand its presence in the area.

     In fiscal 1995, foreign sales accounted for approximately 75% of the
Company's product sales.  The Company believes that the relatively high level of
foreign sales reflects, in part, a more advanced regulatory status for drug
therapies for osteoporosis in certain foreign countries than in the United
States.  Additionally, the large percentage of foreign sales in Japan in fiscal
1994 reflect a government initiative in Japan to provide wide-spread screening
for women's health problems such as osteoporosis and the Company's efforts to
develop new foreign markets.  The Company's foreign sales are subject to risks
generally associated with foreign sales, including United States and foreign
regulatory approval requirements and policy changes.  The relative strength of
the United States dollar in relation to foreign currencies may also adversely
affect the Company's sales to foreign countries.  The Company also believes that
its sales to Europe may be seasonal, with reduced orders in the summer months
reflecting summer vacation schedules.  International sales will also be affected
by government approval of new drug therapies, changes in local health care
policies regarding reimbursement and the strength of promotional efforts by its
distributors.  See "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and Note 11 of Notes to Consolidated Financial
Statements.

COMPETITION
   
                                       14
<PAGE>
 
     The bone assessment market is highly competitive and characterized by
continual change and improvement in technology, and multiple technologies that
have been or are under development.  Some of the companies in this industry have
significantly greater manufacturing, marketing and financial resources than the
Company.   See "Background."

     Four companies, Lunar, Norland Medical Systems, Aloka and Hitachi, have
developed DXA systems to measure bone density which compete with the Company's
systems.  The Company believes that competition in the field of DXA bone
densitometry is based upon their price, precision, speed of measurement, patient
radiation dose, cost and ease of operation, product versatility, product
reliability and quality of service.  The Company believes that it competes
effectively with respect to these criteria.   The Company believes that its DXA
systems will also compete with other X-ray based modalities, including an
radiographic absorptiometry product developed by CompuMed Inc. which has been
licensed to Merck. The Company's DXA systems also compete with specially-
equipped CT scanners and may compete with used and refurbished DXA systems.  See
"Background" for a discussion of the technical advantages and disadvantages of
these other systems.

     Several companies, including Igea SPA, McCue Ultrasonics, Lunar, Myriad
Ultrasound, Osteometer and Osteo-Sciences have developed ultrasound systems to
assess bone mineral status.  Some of these companies have had substantially more
experience than the Company in developing and marketing their systems. The
Company believes that competition in the field of ultrasound systems is based on
price, precision, speed of measurement, cost and ease of operation, product
versatility, product reliability and quality of service.  The Company believes
that advantages of its Sahara ultrasound bone analyzer system under development
will include the system's dry operation, simple single-button operation, and a
compact and self-contained design that does not require the use of a separate
computer.  No ultrasound bone analyzer has been approved for commercial sale in
the United States.  The timing of FDA clearance or approval for ultrasound bone
analyzers in the United States, developed by the Company and others, could have
a significant impact on their respective market shares.  The Company believes
that ultrasound systems will compete with DXA systems in the diagnostic market
for initial screening of patients.  However, the Company believes that because
ultrasound systems can only measure peripheral skeletal sites and do not have
the precision of DXA systems, DXA systems will continue to be the predominant
means of monitoring bone density for patients being treated for or at high risk
of osteoporosis.

     Three companies have obtained FDA clearance to market biochemical marker
tests that evaluate bone turnover in a microtitre format.  Ostex International
and Metra Biosystems have been cleared to market biochemical markers that assess
bone resorption.  Hybritech and Metra Biosystems have been cleared to market
biochemical markers that assess bone formation.  One or more of these companies
may develop point-of-care, over-the-counter or other biochemical marker tests
that would compete with the biochemical marker strip tests being developed by
the Company and Serex.  Competition in this market will be based upon price,
product reliability, diagnostic sensitivity, precision and ease of use.  There
can be no assurance that the Company and Serex will be able to compete
effectively in this market.

MANUFACTURING
   
                                       15
<PAGE>
 
     The Company's manufacturing operations for its DXA and ultrasound systems
consist primarily of assembly, test, burn-in and quality control.  The Company
purchases a major portion of the parts and peripheral components for its
products, and manufactures certain subsystems, such as the high-voltage X-ray
power supply, from raw materials.  Parts and materials are readily available
from several supply sources.

     The Company is required to purchase all of its requirements for Scanora
from Soredex.  Failure of Soredex to manufacture those systems on time and in
accordance with specifications would have an adverse impact on the Company's
sales of those systems.

BACKLOG

     Backlog for the Company's systems as of November 30, 1995 and 1994 totaled
approximately $4.6 million and $4.9 million, respectively.  Backlog consists of
purchase orders for which a delivery schedule within the next twelve months has
been specified by the customer.  Orders included in backlog may be canceled or
rescheduled by customers without significant penalty.  Backlog as of any
particular date should not be relied upon as indicative of the Company's net
revenues for any future period.

RESEARCH AND DEVELOPMENT

     The Company's research and development efforts are focused on enhancing its
existing products and developing new products for the bone assessment market.
The Company's research and development personnel also are involved in
establishing protocols, monitoring and interpreting and submitting test data to
the FDA and other regulatory agencies to obtain the requisite clearances and
approvals for its products.  At November 30, 1995, the Company had 32 persons
engaged in research and development, of whom 23 persons were engaged in the
enhancement of the DXA product line and nine persons were engaged in the
development and enhancement of the Company's ultrasound systems.  Of these
persons, ten persons were engaged in software development.  The research and
development group was responsible for the introduction of the Company's fourth
generation QDR ACCLAIM series of DXA bone densitometers during 1995 and the
ongoing development of the Company's Sahara bone analyzer.   During fiscal 1995,
1994 and 1993, the Company's research and product development expenses were
approximately $4.3 million, $3.4 million and $3.2 million, respectively.

PATENTS AND PROPRIETARY RIGHTS

     The Company relies upon trade secrets and patents to protect its
technology.  Due to the rapid technological change that characterizes the
medical instrumentation industry, the Company believes that the improvement of
existing products, reliance upon trade secrets and unpatented proprietary know-
how and the development of new products are generally as important as patent
protection in establishing and maintaining a competitive advantage.
Nevertheless, the Company has obtained patents and will continue to make efforts
to obtain patents, when available, in connection with its product development
program.  The Company has obtained ten patents, licensed three patents and has
pending 17 patent applications in the United States relating to its DXA
technology, and has obtained three patents, licensed four patents 
   
                                       16
<PAGE>
 
and has pending two patent applications in the United States relating to its
ultrasound technology. The Company has obtained or applied for corresponding
patents and patent applications for certain of these patents and patent
applications in certain foreign countries. There can be no assurance that any of
the Company's patent applications will be granted or that any patent or patent
application will provide significant protection for the Company's products and
technology. Moreover, there can be no assurance that foreign intellectual
property laws will protect the Company's intellectual property rights. In the
absence of significant patent protection, the Company may be vulnerable to
competitors who attempt to copy the Company's products, processes or technology.

     In September 1994, Serex granted the Company an exclusive license to use
Serex's technology to manufacture, market, sell and distribute the bio-chemical
marker strip test being developed under a joint development agreement between
Serex and the Company.  Serex further granted the Company the right of first
negotiation with respect to the development and distribution of new products
conceived of by Serex for application in bone metabolism.  In order to maintain
its exclusive rights, the Company is required to purchase a certain minimum
number of tests or pay Serex amounts that would have been paid had the Company
purchased the minimum number of tests.  If the Company does not meet these
minimum requirements, its rights become nonexclusive.

     In June 1989, the Company granted an exclusive worldwide license of certain
of its DXA technology to Vivid Technologies, Inc., an affiliate of S. David
Ellenbogen and Jay A. Stein, the Chief Executive Officer and Senior Vice
President of the Company, for the sole purpose of developing a baggage
inspection and security system.

     Until recently, the Company had been involved in extensive patent
litigation with Lunar, with each party claiming that the other was infringing
certain patents held by the other.  This litigation was settled by agreement
dated November 22, 1995.  The agreement provides for certain royalties to be
paid by each party to the other for future sales of products using certain
defined technologies.  The Company does not believe that amounts to be paid by
either party under this arrangement will be material.  The agreement also
provides that neither party will engage the other party in patent litigation for
a period of ten years following the date of the agreement, regardless of the
infringement claimed and regardless of whether the technology in question
currently exists or is developed or acquired by the other party in the future.
Neither party is required to disclose to the other any of its technology during
this ten year period or otherwise.  However, there can be no assurance that
Lunar will not use the Company's technology in a manner that would materially
and adversely affect the Company's business and results of operations.

THIRD PARTY REIMBURSEMENT

     In the United States, the Health Care Finance Administration, which
establishes guidelines for the reimbursement of health care providers treating
Medicare and Medicaid patients, provided validation for DXA bone densitometry
examinations as a clinically useful procedure by recommending the reimbursement
for DXA bone evaluations at an initial rate of $68 per scan effective April
1994, which was increased to $124, effective January 1995.  
   
                                       17
<PAGE>
 
The actual reimbursement amounts provided for DXA examinations is determined by
the individual state Medicare carriers. As of December 1995, several of the more
populous states, including California, Connecticut, New York, New Jersey and
Pennsylvania, had no or only partial reimbursement of DXA examinations. In part
as a result of HCFA's recommendations, bone density examinations are paid for by
many private third party insurers in the United States.

     In several European countries, Japan and other international markets, there
has generally been an earlier adoption of reimbursement for bone densitometry
exams.   Countries in which reimbursement for the use of X-ray bone
densitometers has been approved include Belgium, Brazil, Canada, Germany,
Greece, Japan, South Korea, Spain and Switzerland.  In addition, in Japan, where
there is a general aversion to ionizing devices, the government has initiated a
program to subsidize purchases of ultrasound bone densitometers.  As a result,
there is much greater use of ultrasound bone densitometers than in any other
country.  However, DXA bone densitometers continue to account for a substantial
portion of the Japanese market.

REGULATION

     The medical devices manufactured and marketed by the Company are subject to
regulation by the FDA and, in many instances, by foreign governments.  Under the
Federal Food, Drug and Cosmetic Act (the "FDA Act"), manufacturers of medical
devices must comply with certain regulations governing the testing,
manufacturing, packaging and marketing of medical devices.  The Company's
products are also subject to the Radiation Control for Health and Safety Act,
administered by the FDA, which imposes performance standards and record keeping,
reporting, product testing and product labeling requirements for devices using
radiation, such as X-rays.

     The FDA generally must approve the commercial sale of new medical devices.
Commercial sales of the Company's medical devices within the United States must
be preceded by either a premarket notification filing pursuant to Section 510(k)
of the FDA Act or the granting of a premarket approval.  The 510(k)
notification filing must contain information that establishes that the device is
substantially equivalent to an existing device that has been continuously
marketed since May 28, 1976.  The Company received FDA market clearance under
510(k) for its DXA bone densitometers and expects to be eligible to seek 510(k)
clearance for its biochemical marker strip test for use by physicians, once
developed.

     The premarket approval procedure involves a more complex and lengthy
testing and review process by the FDA than the 510(k) premarket notification
procedure and often requires at least several years to obtain.  The Company must
first obtain an investigational device exemption ("IDE") for the product to
conduct extensive clinical testing of the device to obtain the necessary
clinical data for submission to the FDA.  The FDA will thereafter only grant
premarket approval if, after evaluating this clinical data, it finds that the
safety and efficacy of the product has been sufficiently demonstrated.  This
approval may restrict the number of devices distributed or require additional
patient follow-up for an indefinite period of time.  The Company believes that
the approval to market its ultrasound products and its over-the-counter
   
                                       18
<PAGE>
 
biochemical market strip test, once developed, in the United States may be
subject to this more stringent FDA review process.

     The Company's systems are also subject to approval by certain foreign
regulatory and safety agencies.  The Company is awaiting regulatory approval of
the Company's QDR 4500 ACCLAIM systems in Japan and certain other foreign
countries, and has obtained the requisite regulatory approvals for the systems
in certain other countries.

     No assurance can be given that the FDA or foreign regulatory agencies will
give the requisite approvals or clearances for any of the Company's medical
devices under development on a timely basis, if at all.  Moreover, after
clearance is given, these agencies can later withdraw the clearance or require
the Company to change the device or its manufacturing process or labeling, to
supply additional proof of its safety and effectiveness, or to recall, repair,
replace or refund the cost of the medical device, if it is shown to be hazardous
or defective.  The process of obtaining clearance to market products is costly
and time-consuming and can delay the marketing and sale of the Company's
products.

     As a manufacturer of medical devices, the Company is subject to certain
other FDA regulations and the Company's manufacturing processes and facilities
are subject to continuing review by the FDA.  Most states and certain other
foreign countries monitor and require licensing of X-ray devices.  Federal,
state and foreign regulations regarding the manufacture and sale of medical
devices are subject to future change.  The Company cannot predict what impact,
if any, such changes might have on its business.

EMPLOYEES

     As of November 30, 1995, the Company had 191 full-time employees, including
53 in manufacturing operations, 32 in research and development, 71 in marketing,
sales and support services, 27 in finance and administration and eight in
medical data management.  None of the Company's employees are represented by a
union.  The Company considers its employee relations to be good.


ITEM 2.  PROPERTIES

     The Company leases a 83,500 square foot building located in Waltham,
Massachusetts. The initial term of the lease expires in June 1996, with the
Company having an option to extend the lease for an additional four years.  The
Company has subleased approximately 26,500 square feet of this space to Vivid,
an affiliate of Mr. Ellenbogen and Dr. Stein.  During fiscal 1995, Vivid paid
the Company approximately $320,000 for this space.  The Company and Vivid have

ITEM 3.  LEGAL PROCEEDINGS.

     On November 22, 1995, the Company and Lunar entered into a settlement
agreement relating to litigation involving allegations of each party against the
other of patent infringement.  See "Item 1 --Patents and Proprietary Rights."

     Until recently, the Company had been involved in litigation brought in
January  1995 by B.V. Optische Industrie de Oude Delft and two subsidiaries
("Oldelft") claiming damages relating to a prior patent dispute.  On December
14, 1995, the United States District Court for the Southern District of New York
granted the Company's Motion to Dismiss and dismissed all claims against the
Company.  While the court granted Oldelft leave to replead its complaint, no
action has been filed with the court to date.

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

     No matters were submitted to a vote to the Company's security holders
during the fourth quarter of the fiscal year ended September 30, 1995.

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

OVERVIEW

     Since inception, the Company has experienced generally increasing annual
sales as interest in bone diseases, such as osteoporosis, has grown, as new drug
therapies have become available in the United States and other countries to
treat these diseases and as the use of DXA systems to measure bone density has
become more widespread.  The Company's revenues increased 75% to $43.4 million
in 1995 from $24.8 million in 1993.   During 1995, the Company's net income was
adversely impacted by litigation costs of $2.5 million, or $0.41 per share,
incurred in connection with the Company's dispute with Lunar, which was settled
in November 1995, and, to a lesser extent, its dispute with Oldelft which was
dismissed in December 1995.  In fiscal 1993, the Company's sales dropped
slightly from fiscal 1992 as a result of certain recessionary economic trends in
Europe and a significant reduction of United States sales due to uncertainty
over the direction of proposed healthcare reform.  In fiscal 1994 and 1995, the
economic climate in Europe steadily improved and the uncertainty over United
States government reform of the healthcare system abated.  In addition, the
Company was successful in its efforts to develop new international markets in
Latin America and the Pacific Rim.

     The Company commenced operations in April 1986 and was primarily engaged
in product development through the end of fiscal 1987.  The Company shipped the
first QDR 1000 for clinical testing in June 1987 and began commercial shipments
of the system in October 1987 upon receipt of FDA marketing clearance.  The
Company introduced a bone densitometer capable of assessing the bone density of
the entire body in 1989, introduced the first bone densitometer capable of
taking supine lateral measurements of the spine in 1991, and introduced its
fourth generation clinically-oriented QDR 4500 ACCLAIM series of bone
densitometers at the annual meeting of the Radiological Society of North America
in November 1994.  The Company's shipments of its high-end QDR 4500A ACCLAIM
began in January 1995 and of its entire ACCLAIM product line began in the third
quarter of fiscal 1995.  In the fourth quarter of fiscal 1995, ACCLAIM sales
represented approximately 70% of the Company's total DXA sales.  The Company
achieved a slightly higher gross margin on this product line because of higher
selling prices and lower overall manufacturing costs than the older DXA line.

                                       23
<PAGE>
 
The Company believes that the two major drivers of the growth in demand for its
bone densitometers are (i) the availability of new and effective drug therapies
to treat and prevent bone diseases, including osteoporosis, and (ii) the
availability of reimbursement to healthcare providers for bone density
measurements of patients.  On September 29, 1995, the FDA cleared for marketing
Merck's new bisphosphonate, Fosamax, for treatment of established osteoporosis
in post-menopausal women.  The Health Care Finance Administration, the agency
which administers Medicare, increased the recommended reimbursement rate for DXA
tests to a national average of $124, effective January 1, 1995, from $68, the
original recommended reimbursement rate which went into effect in April 1994.

FISCAL YEARS ENDED SEPTEMBER 30, 1995, SEPTEMBER 24, 1994 AND SEPTEMBER 25, 1993

     REVENUES. Total revenues were $43.4 million in fiscal 1995, $38.5 million
in fiscal 1994 and $24.8 million in fiscal 1993. The increase in total revenues
of 13% in fiscal 1995 compared to fiscal 1994 was primarily due to the increase
in the total number of DXA product shipments in both the Company's domestic and
international markets, particularly to Europe where product sales increased 30%
over the prior year. During fiscal 1995, there was also a shift in product sales
mix to the Company's new line of bone densitometers, the ACCLAIM series, which
the Company began shipping in January 1995. The new ACCLAIM products have higher
average selling prices than the comparable DXA bone densitometers which they
replace. For the current year, sales of the ACCLAIM product accounted for over
42% of product sales. The increase in total revenues in fiscal 1994 compared to
1993 was primarily due to the increase in the total number of DXA product
shipments in both the Company's domestic and international markets, particularly
Japan where the Company's distributor accounted for 28% of product sales in
fiscal 1994. During fiscal 1994, there was also a shift in product sales mix
from fiscal 1993, with an increased percentage of sales being derived from the
higher-priced QDR 2000plus and QDR 2000 systems, and an increase in sales of two
X-ray products which the Company began to sell as a distributor, primarily in
Europe.

     Other revenues consist of royalty revenues from the Company's licensing of
its technology to a related party and revenue relating to medical data
management services provided to pharmaceutical companies to assist in the
collection and monitoring of clinical trial data. In fiscal 1995, other revenue
increased 59% to $2.3 million from $1.4 million in fiscal 1994,

                                       25
<PAGE>
 
primarily due to an increase in revenue for medical data management services. In
fiscal 1994, other revenue increased 101% from $710,000 in fiscal 1993 primarily
due to an increase in royalty revenues and, to a lesser extent, an increase in
revenue relating to medical data management services. See "Business --
Customers" and "Business -- Patents and Proprietary Rights."

     In fiscal 1995, approximately 37% of product sales were generated in
Europe, 29% in Asia, 25% in the United States and 9% in other international
markets. In fiscal 1994, approximately 38% of product sales were generated in
Asia, 31% in Europe, 26% in the United States and 5% in other international
markets. In fiscal 1993, approximately 51% of product sales were generated in
Europe, 26% in the United States, 17% in Asia and 6% in other international
markets. The Company expects that foreign sales in the current fiscal year will
continue to account for a substantial portion of product sales.

     COSTS AND EXPENSES. The cost of product sales decreased as a percentage of
product sales to 54% in fiscal 1995 from 56% in fiscal 1994 and from 57% in
fiscal 1993. In fiscal 1995, these costs decreased as a percentage of product
sales primarily due to the Company initiating shipments of its new family of DXA
bone densitometers, the ACCLAIM series, and a volume increase in the number of
DXA systems sold resulting in certain manufacturing efficiencies. The Company
began selling the ACCLAIM product in the second quarter of fiscal 1995 and has
recognized higher gross margins than on the older DXA product line from higher
average selling prices and lower labor and overhead-related manufacturing costs.
In fiscal 1994, the cost of product sales decreased as a percentage of product
sales primarily due to the volume increase in the number of DXA systems sold and
the associated manufacturing efficiencies. These gross margin improvements were
offset somewhat by increased sales of X-ray systems, which are distributed but
not manufactured by the Company in Europe, resulting in an overall gross margin
percentage that is less than what is earned on the DXA product line.

     Research and development expenses increased 25% to $4.3 million (10% of
total revenues) in fiscal 1995 from $3.4 million (9% of total revenues) in
fiscal 1994 primarily due to the addition of engineering personnel and outside
consultants working on the development of new products and the funding of Serex
to develop a biochemical marker strip test. In fiscal 1994, research and
development expenses increased from $3.2 million (13% of total revenues) in
fiscal 1993 primarily due to the addition of engineering personnel working on
the development of new products and due to higher prototype material costs
associated with the Company's new fourth-generation QDR 4500 ACCLAIM bone
densitometers.

     Selling and marketing expenses increased 33% to $7.8 million (19% of
product sales) in fiscal 1995 from $5.9 million (16% of product sales) in fiscal
1994. The increase in fiscal 1995 expenses was primarily due to an increase in
sales personnel and related expenses, marketing and promotional costs incurred
in connection with the introduction of the QDR 4500 ACCLAIM product and
increased sales commissions based on the higher sales volume. In fiscal 1994,
selling and marketing expenses increased 8% from $5.5 million (23% of product
sales) in fiscal 1993. The increase in fiscal 1994 from 1993 was primarily due
to increased sales commissions based on the higher sales volume, especially in
North America and Latin America where the Company sells directly to end-user
customers. In addition, the Company incurred additional

                                       26
<PAGE>
 
costs in connection with its initiation of a formal new business development
effort, which has resulted in the Company's recent product acquisitions and
strategic alliances. The decrease in expenses as a percentage of product sales
in fiscal 1994 was due to the significant increase in sales volume to
distributors which generally do not receive commissions.

     General and administrative expenses increased to $4.5 million (10% of total
revenues) in fiscal 1995 from $4.2 million (11% of total revenues) in fiscal
1994 and $3.5 million (14% of total revenues) in fiscal 1993. The increase in
fiscal 1995 was primarily due to increased head count and other compensation-
related expenditures. The increase in fiscal 1994 when compared to fiscal 1993
was primarily due to increases in accounts receivable reserves, which reflects
the increase in accounts receivable, and an increase in employee incentive
programs. These increases were offset in part by a decrease of general and
administrative expenses in Europe as part of the reorganization begun in the
fourth quarter of fiscal 1993.

     Litigation expenses incurred in fiscal 1995 were in connection with the
Company's disputes with Lunar and Oldelft. Legal expenses in connection with the
patent litigation with Lunar began in October 1994 and represent a substantial
portion of the total litigation expenses. In November 1995, a definitive
agreement that provides for the cross-licensing of certain patent rights
involving DXA and ultrasound technologies for a period of ten years was reached
by the Company and Lunar. The complaint brought by Oldelft against the Company
was dismissed in December 1995. See Item 1 "Business - Patents and Proprietary
Rights" and Item 3 - "Legal Proceedings."

     In the fourth quarter of fiscal 1993, the Company recorded a restructuring
charge of $900,000. This nonrecurring charge covered the reorganization of its
European operations, including consolidation of the distribution and
administrative infrastructure, asset write-offs including receivables and
inventory, and a reduction of its European workforce. The charges from this
restructuring were a result of the weak European economy and the Company's
desire to reallocate its resources to expanding territories with greater growth
potential. At the end of fiscal 1994, the Company's reorganization was complete
and all restructuring charges had been incurred.

     INTEREST INCOME. Interest income increased to $610,000 in fiscal 1995 from
$320,000 in fiscal 1994 as the Company earned a higher rate of return on a
slightly higher investment base than in the prior year and increased the number
of long-term receivables to Latin American customers. In fiscal 1994, interest
income increased from $300,000 in fiscal 1993 as the Company earned a slightly
higher rate of return on a slightly lower investment base than in the preceding
year.

     OTHER EXPENSE. In fiscal 1995 and 1994, the Company incurred other expenses
of $270,000 and $80,000, respectively. These expenses were primarily
attributable to the interest costs on a line of credit established by the
Company in the third quarter of fiscal 1994 for use by the Company's European
subsidiaries to borrow funds in their local currencies to pay for all
intercompany sales, thereby reducing the foreign currency exposure on those
transactions.

                                       27
<PAGE>
 
     In fiscal 1993, the Company recognized other expenses of $440,000 which
primarily represented foreign currency exchange losses, net of hedge
transactions, arising from the Company's United States dollar-denominated sales
to its three European subsidiaries. Approximately one-half of the losses for the
year were incurred in the first quarter, prior to the implementation of the
Company's program to purchase foreign currency forward contracts to hedge its
foreign currency exposure. In 1993, the United States dollar strengthened
significantly against the three foreign currencies (the French franc, the
Belgian franc and the Spanish peseta) in which the subsidiaries conducted
business causing the Company to recognize a transaction loss.

     To the extent that foreign currency exchange rates fluctuate in the future,
the Company may be exposed to continued financial risk. Although the Company has
established a borrowing line denominated in the two foreign currencies (the
French franc and the Belgian franc) in which the subsidiaries currently conduct
business to minimize this risk, there can be no assurance that the Company will
be successful or can fully hedge its outstanding exposure.

     PROVISION FOR INCOME TAXES. The Company's effective tax rate was 25.8% in
fiscal 1995 and 30.8% in fiscal 1994. In fiscal 1993, the Company had a benefit
for income taxes as a result of that year's loss. The Company's effective tax
rate is lower than the statutory tax rates due primarily to the utilization of
tax credits, the utilization of net operating losses in foreign jurisdictions
and tax benefits associated with the Company's foreign sales corporation.

LIQUIDITY AND CAPITAL RESOURCES

     The Company has funded its operations primarily through cash flows from
operations and the issuance of Common Stock. On December 14, 1995 the Company
filed a Registration Statement with the Securities and Exchange Commission with
respect to a proposed offering by the Company of 1,200,000 shares of its Common
Stock. The Company plans to use the net proceeds of the offering, if made, for
general corporate purposes, including working capital, new product development,
sales and marketing expansion and potential acquisitions.

     At September 30, 1995, the Company's working capital was $19.4 million. At
such date, the Company had $9.9 million in cash, cash equivalents and short-term
investments. The current cash, cash equivalents and investments balance
increased approximately $540,000 from September 24, 1994 primarily due to an
increase in the Company's current liabilities, which were partially offset by an
increase in inventories and accounts receivable. The increase in current
liabilities, inventories and accounts receivable reflects the Company's
introduction of its new ACCLAIM family of bone densitometers and the increase in
sales activity. At September 30, 1995, one customer had accounts receivable
outstanding of approximately $2.2 million, which were current within their
payment terms. The Company finances certain sales to Latin America over a two to
three year time frame. At September 30, 1995, the Company had long-term accounts
receivable outstanding of approximately $800,000 relating to these sales, which
were included in other assets. Working capital increased by approximately $1.7
million in fiscal 1995, primarily from the addition of net income. In fiscal
1995, the Company

                                       28
<PAGE>
 
purchased $800,000 of property and equipment, primarily computers and other
equipment associated with the hiring of additional personnel.

     The Company does not currently have any significant capital commitments and
believes that existing sources of liquidity, including the anticipated net
proceeds of the proposed offering, funds expected to be generated from
operations and a $3.0 million credit line for use by its European subsidiaries,
will provide adequate cash to fund the Company's anticipated working capital and
other cash needs for the foreseeable future.

              REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON SCHEDULE



To Hologic, Inc.:


     We have audited in accordance with generally accepted auditing standards,
the consolidated financial statements included in this Form 10-K, and have
issued our report thereon dated November 22, 1995. Our audits were made for the
purpose of forming an opinion on those statements taken as a whole. The schedule
listed in Item 14 (a)(2) is the responsibility of the Company's management and
is presented for purposes of complying with the Securities and Exchange
Commission's rules and is not part of the basic financial statements. This

the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Hologic, Inc.:
 
  We have audited the accompanying consolidated balance sheets of Hologic,
Inc. (a Delaware corporation) and subsidiaries as of September 24, 1994 and
September 30, 1995, and the related consolidated statements of operations,
stockholders' equity and cash flows for each of the three years in the period
ended September 30, 1995. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Hologic, Inc. and
subsidiaries as of September 24, 1994 and September 30, 1995, and the results
of their operations and their cash flows for each of the three years in the
period ended September 30, 1995, in conformity with generally accepted
accounting principles.

                        HOLOGIC, INC. AND SUBSIDIARIES
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) OPERATIONS
 
  Hologic, Inc. (the Company) is engaged in the development, manufacture and
distribution of proprietary x-ray and other medical systems.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  The accompanying consolidated financial statements reflect the application
of certain accounting policies as described in this note and elsewhere in the
accompanying consolidated financial statements.
 
 (a) Principles of Consolidation
 
  The accompanying consolidated financial statements include the accounts of
the Company and all of its wholly owned subsidiaries. All material
intercompany accounts and transactions have been eliminated in consolidation.
 
 (b) Change in Fiscal Year
 
  During fiscal 1993, the Company elected to change its fiscal year-end from
September 30 to the last Saturday in September. Fiscal 1993, 1994 and 1995
ended on September 25, 1993, September 24, 1994 and September 30, 1995.
 
 (c) Management Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 (d) Cash and Cash Equivalents and Short-term Investments
 
  The Company considers all highly liquid investments with maturities of three
months or less at the time of acquisition to be cash equivalents. Included in
cash equivalents at September 24, 1994 is approximately $4,804,000 of
securities purchased under agreements to resell. Included in cash equivalents
at September 30, 1995 is approximately $4,217,000 of securities purchased
under agreements to resell. The securities purchased under agreements to
resell are collateralized by U.S. Government securities. Short-term
investments have maturities of greater than three months and consist of
securities issued by the U.S. Government and its agencies.
 
  The Company accounts for investments in accordance with the Statement of
Financial Accounting Standards (SFAS) No. 115, Accounting for Certain
Investments in Debt and Equity Securities. Under SFAS No. 115, investments
that the Company has the positive intent and ability to hold to maturity are
reported at amortized cost, which approximates fair market value, and are
classified as held-to-maturity. These investments include cash, cash
equivalents and securities issued by U.S. Government agencies, which total
$6,522,000 at September 30, 1995. Investments purchased to be held for
indefinite periods of time and not intended at the time of purchase to be held
until maturity are classified as available-for-sale, which total $1,803,000 at
September 30, 1995. These investments consist of securities issued by the U.S.
Government and are carried at cost which approximates fair market value.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 (e) Concentration of Credit Risk
 
  SFAS No. 105, Disclosure of Information about Financial Instruments with
Off-Balance-Sheet Risk and Financial Instruments with Concentration of Credit
Risk, requires disclosure of any significant off-balance-sheet and credit risk
concentrations. Financial instruments that subject the Company to credit risk
consist primarily of trade accounts receivable. The Company utilizes
distributors in certain countries with various credit terms, depending on the
individual circumstances. One distributor had amounts due to the Company of
approximately $4,817,000 and $2,231,000 as of September 24, 1994 and September
30, 1995, respectively. This distributor accounted for 14%, 28% and 20% of
product sales for fiscal 1993, 1994 and 1995, respectively.
 
 (f) Inventories
 
  Inventories are stated at the lower of cost (first-in, first-out) or market

  Work-in-process and finished goods inventories consist of materials, labor
and manufacturing overhead.
 
 (g) Depreciation and Amortization
 
  The Company provides for depreciation and amortization by charges to
operations, using the straight-line and declining-balance methods, which
allocate the cost of property and equipment over the following estimated
useful lives:

             Furniture and fixtures.....     5-7 Years
             Leasehold improvements..... Life of lease
</TABLE>
 
 (h) Intangible Assets
 
  The Company assesses the realizability of intangible assets in accordance
with SFAS No. 121, Accounting for Impairment of Long-lived Assets and for
Long-lived Assets To Be Disposed Of.
 
 (i) Foreign Currency Translation
 
  The Company translates certain of its accounts and the financial statements
of its foreign subsidiaries in accordance with SFAS No. 52, Foreign Currency
Translation. In translating the accounts of the foreign subsidiaries into U.S.
dollars, assets and liabilities are translated at the rate of exchange in
effect at year-end, while stockholders' equity is translated at historical
rates. Revenue and expense accounts are translated using the weighted average
exchange rate in effect during the year. Gains and losses from foreign
currency translation are credited or charged to cumulative translation
adjustment, included in stockholders' equity in the accompanying consolidated
balance sheets.
 
  Transaction losses of approximately $430,000 in fiscal 1993 are included in
other expense in the accompanying consolidated statements of operations.
Transaction gains in fiscal 1994 and 1995 were not significant.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 (j) Revenue Recognition
 
  The Company recognizes product revenue upon shipment. A provision is made at
that time for estimated warranty costs to be incurred. Other revenues are
recorded at the time the product is shipped or the service rendered.
 
  Maintenance revenues are recognized over the term of the contract. Cash
received in excess of revenues recognized is included in deferred revenue in
the accompanying consolidated balance sheets.
 
 (k) Research and Development and Software Development Costs
 
  Research and development costs, other than software development costs, have
been charged to operations as incurred. SFAS No. 86, Accounting for the Costs
of Computer Software To Be Sold, Leased or Otherwise Marketed, requires the
capitalization of certain computer software development costs incurred after
technological feasibility is established. The Company believes that once
technological feasibility of a software product has been established, the
additional development costs incurred to bring the product to a commercially
acceptable level are not significant.
 
 (l) Net Income (Loss) per Common and Common Equivalent Share
 
  Net income (loss) per share data are computed using the weighted average
number of shares of common stock outstanding during each period. Common
equivalent shares from stock options have been included in the computation
using the treasury stock method only when their effect would be dilutive.
Fully dilutive net income per share has been separately presented only when
the difference from primary net income per share is significant.
 
 (m) Restructuring Charge
 
  In fiscal 1993, the Company recorded a nonrecurring restructuring charge of
$900,000, representing the costs associated with reorganizing its European
operations. These costs included a reduction in work force, consolidation of
distribution and administrative functions, and asset write-offs and write-
downs. The restructuring was completed during the fourth quarter of fiscal
1994.
 
 (n) Derivative Financial Instruments
 
  During October 1994, the Financial Accounting Standards Board issued SFAS
No. 119, Disclosure About Derivative Financial Instruments and Fair Value of
Financial Instruments, which requires disclosures about derivative financial
instruments. SFAS No. 119 will be effective for fiscal 1996. The Company does
not expect the adoption of this standard to have a material effect on its
consolidated financial position or results of operations. At September 30,
1995, the Company had no instruments requiring disclosure under SFAS No. 119.
 
(3) LINE OF CREDIT
 
  The Company maintains a line of credit with a bank for the equivalent of
$3,000,000, which bears interest at the Paris Interbank Offered Rate (6.375%
at September 30, 1995) plus 2.25%. The borrowings under this line are
primarily used by the Company's European subsidiaries to settle intercompany
sales and are denominated in the respective local currencies of its European
subsidiaries. The line of credit may be canceled by the bank with a 30-day
notice. Interest expense on this line of credit of approximately $79,000 and
$204,000 has been included in other expenses in the accompanying consolidated
statements of operations for 1994 and 1995, respectively.

(4) INCOME TAXES

accordance with SFAS No. 109, Accounting for Income Taxes.

statements of operations consists of the following:

foreign jurisdictions, for which realization is uncertain. The reduction in
the valuation allowance in 1995 is directly attributable to the reduction of
foreign net operating losses.

 (b) Employee Stock Purchase Plan
 
  In December 1994, the Company adopted the 1995 Employee Stock Purchase Plan
(the ESP Plan) in compliance with Section 423 of the Internal Revenue Code.
Employees who have completed 12 consecutive months or two years, whether or
not consecutive, of employment with the Company are eligible to participate in
the ESP Plan. The ESP Plan allows participants to purchase common stock of the
Company at 85% of the fair market value, as defined. The Company may issue up
to 100,000 shares under the ESP Plan. During fiscal 1995, the Company issued
4,780 shares under the ESP Plan. At September 30, 1995, the Company has 95,220
shares available for purchase under the ESP Plan.
 
 (c) Rights Agreement
 
  In December 1992, the Company adopted a shareholder rights plan. The plan is
intended to protect shareholders from unfair or coercive takeover practices.
In accordance with the plan, the Board of Directors declared a dividend
distribution of one common stock purchase right for each share of common stock
outstanding until the rights become detachable. Each right entitles the
registered holder to purchase from the Company one share of common stock for
$30, adjusted for certain events. In the event that the Company is acquired in
a merger or other business combination transaction or more than 50% of its
assets or earning power are sold, each holder shall thereafter have the right
to receive, upon exercise of each right, that number of shares of Common Stock
of the acquiring Company which at the time of such transaction would have a
market value of two times the $30 per share exercise price. The rights will
not be detachable or exercisable until certain events occur. The Board of
Directors may elect to terminate the rights under certain circumstances.
 
(6) PROFIT-SHARING 401(K) PLAN
 
  The Company has a qualified profit-sharing plan covering substantially all
of its employees. Contributions to the plan are at the discretion of the
Company's Board of Directors. The Company has recorded approximately $98,000,
$120,000 and $135,000 as a provision for the profit-sharing contribution for
fiscal 1993, 1994 and 1995, respectively.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

(13) LITIGATION
 
  On September 7, 1994, Lunar Corporation (Lunar) filed a complaint in United
States District Court against the Company, alleging, among other things, that
two of the Company's patents are not valid and infringe on three of Lunar's
patents. The Company filed a counterclaim against Lunar with respect to the
infringement of two of the Company's patents and a declaration that certain of
Lunar's patents are invalid and unenforceable.
 
  On November 22, 1995, the Company and Lunar executed a definitive agreement
settling all disputes between the parties. The agreement provides for the
cross-licensing of certain patent rights and continuing payments between the
parties related to future sales. The Company and Lunar have agreed not to
engage each other in patent litigation in the area of x-ray densitometry and
ultrasound for a ten-year period. Management believes that the financial terms
of this agreement will not have a material adverse effect on the Company's
financial position or results of operations.
   
  On January 24, 1995, B.V. Optische Industrie de Oude Delft (Oldelft) filed
suit in the United States District Court against the Company seeking
unspecified treble damages, attorneys' fees and costs relating to a prior
patent dispute between the Company and Oldelft relating to equalization
radiography. On December 14, 1995, the litigation was dismissed by the United
States District Court. Management believes that the outcome of this dispute
will not have a material adverse effect on the Company's financial position or
results of operations.

                             AMENDED AND RESTATED
                 1990 NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN

    1.   Purpose.  The purpose of this 1990 Non-Employee Director Stock Option
Plan is to attract and retain the services of experienced and knowledgeable
independent directors of the Corporation for the benefit of the Corporation and
its stockholders and to provide additional incentives for such independent
directors to continue to work for the best interests of the Corporation and its
stockholders through continuing ownership of its common stock.

    2.   Definitions.  As used herein, each of the following terms has the
indicated meaning:

    "Corporation" means Hologic, Inc.

    "Eligible Director" means each director of the Corporation who is not then
an employee of the Corporation or affiliated with any holder of more than 5% of
the outstanding voting stock of the Corporation.

    "Fair Market Value" means the last sale price of the Shares as reported on
the National Association of Securities Dealers Automated Quotation System
("NASDAQ") or on a national securities exchange on which the Shares may be
traded on the date of the granting of the Option, or if such date is not a
business day, the first business day preceding such grant. If the Shares are not
publicly traded, the fair market value shall mean the fair market value of the
Shares as determined by the Board of Directors.

    "Option" means the contractual right to purchase Shares upon the specific
terms set forth in this Plan.

    "Option Exercise Period" means the period commencing on the date of grant of
an Option pursuant to this Plan and ending ten years from the date of grant.

    "Plan" means this amended and restated Hologic, Inc. 1990 Non-Employee
Director Stock Option Plan.

    "Shares" means the Common Stock, $.01 par value, of the Corporation.

    3.   Stock Subject to the Plan.  The aggregate number of Shares that may be
issued and sold under the Plan shall be 100,000 shares. The Shares to be issued
upon exercise of Options granted under this Plan shall be made available, at the
discretion of the Board of Directors, from (i) treasury Shares and/or Shares
reacquired by the Corporation for such purposes, including Shares purchased in
the open market, (ii) authorized but unissued Shares, and (iii) Shares
previously reserved for issuance upon exercise of Options which have expired or
been terminated. If any Option granted under this Plan shall expire or terminate
for any reason without having been exercised in full, the unpurchased Shares
covered thereby shall become available for grant as additional Options under the
Plan so long as it shall remain in effect.

    4.   Administration of the Plan.  The Plan shall be administered by the
Board of Directors of the Corporation (the "Board"). The Board shall, subject to
the provisions of the Plan, grant options under the Plan and shall have the
power to construe the Plan, to determine all questions as to eligibility, and
<PAGE>
 
to adopt and amend such rules and regulations for the administration of the Plan
as it may deem desirable. The Board may delegate any and all of its authority
hereunder to one or more Committees of the Board.

    5.   Eligibility; Grant of Options.  Each Eligible Director shall be granted
an option to acquire 5,000 Shares (the "Initial Option") effective on the date
he or she is first elected to the Board. In addition, each Eligible Director who
has served as a Director for a full fiscal year will be entitled to receive
options to purchase an additional 4,000 shares of Common Stock on December 15 of
each year (provided the director continues to be an Eligible Director on that
Date) until the director has received options to purchase 22,000 additional
shares (the "Additional Options").

    6.   Terms of Options and Limitations Thereon.

         (a) Option Agreement.  Each Option granted under this Plan shall be
evidenced by an option agreement between the Corporation and the Option holder
and shall be upon such terms and conditions not inconsistent with this Plan as
the Board may determine. Each Option shall explicitly state that it is not
intended to be an "incentive stock option" as that term is defined in Section
422 of the Internal Revenue Code.

         (b) Price.  The price at which any Shares may be purchased pursuant to
the exercise of an Option shall be the Fair Market Value of the Shares on the
date of grant, but in no event shall the price be less than the par value of the
Shares.

         (c) Exercise of Options.  Subject to Paragraph 7 of this Plan, each
Option granted under this Plan may be exercised in full at one time or in part
from time to time only during the Option Exercise Period on the giving of
written notice, signed by the person or persons exercising the Option, to the
Corporation stating the numbers of Shares with respect to which the Option is
being exercised, accompanied by full payment for such Shares pursuant to
Paragraph 7(b) hereof; provided however, (i) if a person to whom an Option has
been granted is permanently disabled or dies during the Option Exercise Period,
the portion of such Option then exercisable, as provided in Paragraph 7(a),
shall be exercisable by him or her or by the executors, administrators, legatees
or distributees of his or her estate during the 12 months following his or her
or death or permanent disability and, (ii) if a person to whom an Option has
been granted ceases to be a director of the Corporation for any cause other than
death or permanent disability, the portion of Option then exercisable shall be
exercisable during the thirty (30) day period following the date such person
ceased to be a director, but, in any event, only to the extent vested pursuant
to Paragraph 7(a) hereof.

         (d) Non-Assignability.  No Option or right or interest in an Option
shall be assignable or transferable by the holder except by will or the laws of
descent and distribution and during the lifetime of the holder shall be
exercisable only by him or her.

    7.   Vesting; Payment.

         (a) Options granted under this Plan may be exercised as follows: the
Initial Options may be exercised during the Option Exercise Period at the rate
of 20% per year, commencing one year after the date of grant, such that the
Option may be exercised in full from and after five years from the date of
grant, and the Additional Options may be exercised during the Option Exercise
Period at any time after six months from the date of grant.

         (b) The purchase price of Shares upon exercise of an Option shall be
paid by the Option holder in full upon exercise and may be paid (i) in cash,
(ii) by delivery of Shares having a Fair Market Value on the date of

                                      -2-
<PAGE>
 
exercise equal to the purchase price, or (iii) any combination of cash and
Shares, as the Board may determine.

         (c) No Shares shall be issued or transferred upon exercise of any
Option under this Plan unless and until all legal requirements applicable to the
issuance or transfer of such shares and such other requirements as are
consistent with the Plan have been complied with to the satisfaction of the
Board, including without limitation those described in Paragraph 10 hereof.

    8.   Stock Adjustments.

         (a) If the Corporation is a party to any merger or consolidation, any
purchase or acquisition of property or stock, or any separation, reorganization
or liquidation, the Board (or, if the Corporation is not the surviving
corporation, the Board of Directors of the surviving corporation) shall have the
power to make arrangements, which shall be binding upon the holders of unexpired
Options, for the substitution of new options for, or the assumption by another
corporation of, any unexpired Options then outstanding hereunder.

         (b) If by reason of recapitalization, reclassification, stock split-up,
combination of shares, separation (including a spin-off) or dividend on the
Stock payable in Shares, the outstanding Shares of the Corporation are increased
or decreased or changed into or exchanged for a different number or kind of
shares or other securities of the Corporation, the Board shall conclusively
determine the appropriate adjustment in the exercise prices of outstanding
Options and in the number and kind of shares as to which outstanding Options
shall be exercisable.

         (c) In the event of a transaction of the type described in Paragraphs
(a) and (b) above, the total number of Shares on which Options may be granted
under this Plan shall be appropriately adjusted by the Board.

    9.   No Rights Other Than Those Expressly Created. No person affiliated with
the Corporation or other person shall have any claim or right to be granted an
Option hereunder. Neither this Plan nor any action taken hereunder shall be
construed as (i) giving any Option holder any right to continue to be affiliated
with the Corporation, (ii) giving any Option holder any equity or interest of
any kind in any assets of the Corporation, or (iii) creating a trust of any kind
or a fiduciary relationship of any kind between the Corporation and any such
person. No Option holder shall have any of the rights of a stockholder with
respect to Shares covered by an Option until such time as the Option has been
exercised and Shares have been issued to such person.

    10.  Miscellaneous.

         (a) Withholding of Taxes.  Pursuant to applicable federal, state, local
or foreign laws, the Corporation may be required to collect income or other
taxes upon the grant of an Option to, or exercise of an Option by, a holder. The
Corporation may require, as a condition to the exercise of an Option, that the
recipient pay the Corporation, at such time as the Board determines, the amount
of any taxes which the Board may determine is required to be withheld.

         (b) Securities Law Compliance.  Upon exercise of an Option, the holder
shall be required to make such representations and furnish such information as
may, in the opinion of counsel for the Corporation, be appropriate to permit the
Corporation to issue or transfer the Shares in compliance with the provisions of
applicable federal or state securities laws. The Corporation, in its discretion,
may postpone the issuance and delivery of Shares upon any exercise of an Option
until completion of such registration or other qualification of such Shares
under any federal or state laws, or stock

                                      -3-
<PAGE>
 
exchange listing, as the Corporation may consider appropriate. The Corporation
is not obligated to register or qualify the Shares under federal or state
securities laws and may refuse to issue such Shares if neither registration nor
exemption therefrom is practical. The Board may require that prior to the
issuance or transfer of any Shares upon exercise of an Option, the recipient
enter into a written agreement to comply with any restrictions on subsequent
disposition that the Board or the Corporation deems necessary or advisable under
any applicable federal and state securities laws. Certificates representing the
Shares issued hereunder may be legended to reflect such restrictions.

         (c) Indemnity.  The Board shall not be liable for any act, omission,
interpretation, construction or determination made in good faith in connection
with its responsibilities with respect to the Plan, and the Corporation hereby
agrees to indemnify the members of the Board, in respect of any claim, loss,
damage, or expense (including counsel fees) arising from any such act, omission,
interpretation, construction or determination to the full extent permitted by
law.

    11.  Effective Date; Amendment; Termination.

         (a) The effective date of this Plan shall be the date of the approval
of stockholders of the Corporation holding at least a majority of the voting
stock of the Corporation.

         (b) The date of grant of any Option granted hereunder shall be the date
upon which the Eligible Director to whom the Option is granted becomes a
director of the Company.

         (c) The Board, or any Committee who has been delegated the authority to
do so, may at any time, and from time to time, amend, suspend or terminate this
Plan in whole or in part. Provided however, that so long as there is a
requirement under Rule 16b-3 under the Securities Exchange Act of 1934, as
amended, for stockholder approval of a Plan and certain amendments thereto, any
such amendment which (i) materially increases the number of Shares which may be
subject to Options granted under the Plan, (ii) materially increases the
benefits accruing to participants in the Plan, or (iii) materially modifies the
requirement for eligibility to participate in the Plan, shall be subject to
stockholder approval, to the extent so required under said Rule; and provided
further that the Plan may not be modified more often than once every six months
to materially modify (i) the requirements for eligibility under the Plan, (ii)
the timing of the grants of Options under the Plan or (iii) the number of Shares
subject to Options to be granted under the Plan. Except as provided herein, no
amendment, suspension or termination of this Plan may adversely affect the
rights of any person under an Option that has been granted to such person
without such person's consent.

         (d) This Plan shall terminate January 3, 2000, and no Option shall be
granted under this Plan thereafter, but such termination shall not affect the
validity of Options granted prior to the date of termination.

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

     SECTION I.  PURPOSE OF THE PLAN.

     The purposes of this Hologic, Inc. 1995 Combination Stock Option Plan (the
"1995 Plan") are (i) to provide long-term incentives and rewards to those key
employees (the "Employee Participants") of Hologic, Inc. (the "Corporation") and
its subsidiaries (if any), and any other persons (the "Non-employee
Participants") who are in a position to contribute to the long-term success and
growth of the Corporation and its subsidiaries, (ii) to assist the Corporation
in retaining and attracting executives and key employees with requisite
experience and ability, and (iii) to associate more closely the interests of
such executives and key employees with those of the Corporation's stockholders.
Notwithstanding the foregoing, if Section 16, as defined in Section II, is
applicable to the Corporation, then any director of the Corporation who is a
member of the Committee, as defined in paragraph (a) of Section III, shall not

     SECTION III.  ADMINISTRATION.

     (a) The Committee.  This 1995 Plan shall be administered by a compensation
committee designated by the Board of Directors of the Corporation, which may
include any persons (including any or all of the directors) designated by the
Board of Directors (the administering body is hereafter referred to as the
"Committee"). The Committee shall serve at the pleasure of the Board of
Directors, which may from time to time, and in its sole discretion, discharge
any member, appoint additional new members in substitution for those previously
appointed and/or fill vacancies however caused. A majority of the Committee
shall constitute a quorum and the acts of a majority of the members present at
any meeting at which a quorum is present shall be deemed the action of the
Committee. No person shall be eligible to be a member of the Committee if that
person's membership would prevent the plan from complying with Section 16, if
applicable to the Corporation. At such time as any class of equity security of
the Corporation is registered pursuant to Section 12 of the Securities Exchange
Act of 1934, as amended (the "Act"), (i) the Committee shall consist of at least
two members of the Board of Directors and (ii) no member
                                      
                                      -2-
<PAGE>
 
of the Committee while a member thereof shall be granted Stock Options under
this Plan, nor may any person be appointed to the Committee unless he was not
granted or awarded stock options or shares of Common Stock under this 1995 Plan
or any other plan of the Corporation at any time within the one-year period
immediately prior to such appointment as provided in Rule 16b-3 promulgated
under the Act.

     (b) Authority and Discretion of the Committee.  Subject to the express
provisions of this 1995 Plan and provided that all actions taken shall be
consistent with the purposes of this 1995 Plan, and subject to ratification by
the Board of Directors only if required by applicable law, the Committee shall
have full and complete authority and the sole discretion to: (i) determine those
persons who shall constitute key employees eligible to be Employee Participants;
(ii) select the Participants to whom Stock Options shall be granted under this
1995 Plan; (iii) determine the size and the form of the Stock Options, if any,
to be granted to any Participant; (iv) determine the time or times such Stock
Options shall be granted including the grant of Stock Options in connection with
other awards made, or compensation paid, to the Participant; (v) establish the
terms and conditions upon which such Stock Options may be exercised and/or
transferred, including the exercise of Stock Options in connection with other
awards made, or compensation paid, to the Participant; (vi) make or alter any
restrictions and conditions upon such Stock Options and the Stock received on
exercise thereof, including, but not limited to, providing for limitations on
the Participant's right to keep any Stock received on termination of employment;
(vii) determine whether the Participant or the Corporation has achieved any
goals or otherwise satisfied any conditions or requirements that may be imposed
on or related to the exercise of Stock Options; and (viii) adopt such rules and
regulations, establish, define and/or interpret these and any other terms and
conditions, and make all determinations (which may be on a case-by-case basis)
deemed necessary or desirable for the administration of this 1995 Plan.
Notwithstanding any provision of this 1995 Plan to the contrary, only Employee
Participants shall be eligible to receive 1995 Plan ISOs. If the Common Stock is
registered pursuant to Section 12 of the 1934 Act, then notwithstanding any
provision of this 1995 Plan to the contrary, grants of Stock Options to non-
employee directors must be uniformly offered to all such non-employee directors.

     (c) Applicable Law.  This 1995 Plan, and all Stock Options shall be
governed by the law of the state in which the Corporation is incorporated.

     SECTION IV. TERMS OF STOCK OPTIONS.

     (a) Agreements.  Stock Options shall be evidenced by a written agreement
between the Corporation and the Participant awarded the Stock Option. This
agreement shall be in such form, and contain such terms and conditions (not
inconsistent with this 1995 Plan) as the Committee may determine. If the Stock
Option described therein is not intended to be an Incentive Stock Option, but
otherwise qualifies as an Incentive Stock Option, the agreement shall include
the following, or a similar, statement: "This stock option is not intended to be
an Incentive Stock Option, as that term is described in Section 422 of the
Internal Revenue Code of 1986, as amended."

     (b) Term.  Stock Options shall be for such periods as may be determined by
the Committee, provided that in the case of 1995 Plan ISOs, the term 

                                      -3-
<PAGE>
 
of any such 1995 Plan ISO shall not extend beyond three months after the time
the Participant ceases to be an employee of the Corporation. Notwithstanding the
foregoing, the Committee may provide in a 1995 Plan ISO that in the event of the
Permanent and Total Disability or death of the Participant, the 1995 Plan ISO
may be exercised by the Participant or his estate (if applicable) for a period
of up to one year after the date of such Permanent and Total Disability or
Death. In no event may a 1995 Plan ISO be exercisable (including provisions, if
any, for exercise in installments) subsequent to ten years after the date of
grant, or, in the case of 1995 Plan ISOs granted to Ten Percent Stockholders,
more than five years after the date of grant.

     (c) Purchase Price.  The purchase price of shares purchased pursuant to any
Stock Option shall be determined by the Committee, and shall be paid by the
Participant or other person permitted to exercise the Stock Option in full upon
exercise, (i) in cash, (ii) by delivery of shares of Common Stock (valued at
their Fair Market Value on the date of such exercise), (iii) any other property
(valued at its Fair Market Value on the date of such exercise), or (iv) any
combination of cash, stock and other property, with any payment made pursuant to
subparagraphs (ii), (iii) or (iv) only as permitted by the Committee, in its
sole discretion. In no event will the purchase price of Common Stock be less
than the par value of the Common Stock. Furthermore, the purchase price of
Common Stock subject to a 1995 Plan ISO shall not be less than the Fair Market
Value of the Common Stock on the date of the issuance of the 1995 Plan ISO,
provided that in the case of 1995 Plan ISOs granted to Ten Percent Stockholders,
the purchase price shall not be less than 110% of the Fair Market Value of the
Common Stock on the date of issuance of the 1995 Plan ISO.

     (d) Further Restrictions as to Incentive Stock Options.  To the extent that
the aggregate Fair Market Value of Common Stock with respect to which
Corporation ISOs (determined without regard to this section) are exercisable for
the first time by any Employee Participant during any calendar year exceeds
$100,000, such Corporation ISOs shall be treated as options which are not
Incentive Stock Options. For the purpose of this limitation, options shall be
taken into account in the order granted, and the Committee may designate that
portion of any Corporation ISO that shall be treated as not an Incentive Stock
Option in the event that the provisions of this paragraph apply to a portion of
any option, unless otherwise required by the Code or regulations of the Internal
Revenue Service. The designation described in the preceding sentence may be made
at such time as the Committee considers appropriate, including after the
issuance of the option or at the time of its exercise. For the purpose of this
section, Fair Market Value shall be determined as of the time the option with
respect to such stock is granted.

     (e) Restrictions.  At the discretion of the Committee, the Stock Options,
as well as the Common Stock issued pursuant to the Stock Options, may be subject
to restrictions on vesting or transferability. For the purposes of this
limitation, options shall be taken into account in the order granted.

     (f) Withholding of Taxes.  Pursuant to applicable federal, state, local or
foreign laws, the Corporation may be required to collect income or other taxes
upon the grant of a Stock Option to, or exercise of a Stock Option by, a holder.
The Corporation may require, as a condition to the exercise of a Stock Option,
or demand, at such other time as it may consider appropriate, that the
Participant pay the Corporation the amount of any taxes which the

                                      -4-
<PAGE>
 
Corporation may determine is required to be withheld or collected, and the
Participant shall comply with the requirement or demand of the Corporation. In
its discretion, the Corporation may withhold shares to be received upon exercise
of a Stock Option if it deems this an appropriate method for withholding or
collecting taxes.

     (g) Securities Law Compliance.  Upon exercise (or partial exercise) of a
Stock Option, the Participant or other holder of the Stock Option shall make
such representations and furnish such information as may, in the opinion of
counsel for the Corporation, be appropriate to permit the Corporation to issue
or transfer Stock in compliance with the provisions of applicable federal or
state securities laws. The Corporation, in its discretion, may postpone the
issuance and delivery of Stock upon any exercise of this Option until completion
of such registration or other qualification of such shares under any federal or
state laws, or stock exchange listing, as the Corporation may consider
appropriate. Furthermore, the Corporation is not obligated to register or
qualify the shares of Common Stock to be issued upon exercise of a Stock Option
under federal or state securities laws (or to register or qualify them at any
time thereafter), and it may refuse to issue such shares if, in its sole
discretion, registration or exemption from registration is not practical or
available. The Corporation may require that prior to the issuance or transfer of
Stock upon exercise of a Stock Option, the Participant enter into a written
agreement to comply with any restrictions on subsequent disposition that the
Corporation deems necessary or advisable under any applicable federal and state
securities laws. Certificates of Stock issued hereunder may bear a legend
reflecting such restrictions.

     (h) Right to Stock Option.  No employee of the Corporation or any other
person shall have any claim or right to be a participant in this 1995 Plan or to
be granted a Stock Option hereunder. Neither this 1995 Plan nor any action taken
hereunder shall be construed as giving any person any right to be retained in
the employ of the Corporation. Nothing contained hereunder shall be construed as
giving any person any equity or interest of any kind in any assets of the
Corporation or creating a trust of any kind or a fiduciary relationship of any
kind between the Corporation and any such person. As to any claim for any unpaid
amounts under this 1995 Plan, any person having a claim for payments shall be an
unsecured creditor.

     (i) Indemnity.  Neither the Board of Directors nor the Committee, nor any
members of either, nor any employees of the Corporation or any parent,
subsidiary, or other affiliate, shall be liable for any act, omission,
interpretation, construction or determination made in good faith in connection
with their responsibilities with respect to this 1995 Plan, and the Corporation
hereby agrees to indemnify the members of the Board of Directors, the members of
the Committee, and the employees of the Corporation and its parent or
subsidiaries in respect of any claim, loss, damage, or expense (including
reasonable counsel fees) arising from any such act, omission, interpretation,
construction or determination to the full extent permitted by law.

     (j) Participation by Foreigners.  Without amending this 1995 Plan, except
to the extent required by the Code in the case of Incentive Stock Options, the
Committee may modify grants made to participants who are foreign nationals or
employed outside the United States so as to recognize differences in local law,
tax policy, or custom.

                                      -5-
<PAGE>
 
     SECTION V.   AMENDMENT AND TERMINATION; ADJUSTMENTS UPON CHANGES IN STOCK.

     The Board of Directors of the Corporation may at any time, and from time to
time, amend, suspend or terminate this 1995 Plan in whole or in part; provided,
however, that neither the Board of Directors nor the Committee may materially
amend or modify the definition of Employee Participants, materially increase the
benefits accruing to Participants, increase the number of shares of Common Stock
reserved for purposes of this 1995 Plan, extend the term of this 1995 Plan,
materially modify the requirements to be a Participant in this 1995 Plan, or
otherwise modify this 1995 Plan in any way or manner requiring the approval of
the Stockholders under the Code, or rules and regulations thereunder, or Section
16, if applicable to the Corporation, without Stockholder Approval and
compliance with any applicable law, rules, or regulations. Except as provided
herein, no amendment, suspension or termination of this 1995 Plan may affect the
rights of a Participant to whom a Stock Option has been granted without such
Participant's consent. The Committee is specifically authorized to convert, in
its discretion, the unexercised portion of any 1995 Plan ISO granted to an
Employee Participant to a Non-qualified Option at any time prior to the
exercise, in full, of such 1995 Plan ISO. If there shall be any change in the
Common Stock or to any Stock Option granted under this 1995 Plan through merger,
consolidation, reorganization, recapitalization, stock dividend, stock split or
other change in the corporate structure of the Corporation, appropriate
adjustments may be made by the Committee (or if the Corporation is not the
surviving corporation in any such transaction, the Board of Directors of the
surviving corporation, or its designee) in the aggregate number and kind of
shares subject to this 1995 Plan, and the number and kind of shares and the
price per share subject to outstanding options, provided that such adjustment
does not affect the qualification of any 1995 Plan ISO as an Incentive Stock
Option. In connection with the foregoing, the Committee may issue new Stock
Options in exchange for outstanding Stock Options.

     SECTION VI.  SHARES OF STOCK SUBJECT TO THE PLAN.

     The number of shares of Common Stock that may be the subject of awards
under this 1995 Plan shall not exceed an aggregate of 550,000 shares. Shares to
be delivered under this 1995 Plan may be either authorized but unissued shares
of Common Stock or treasury shares. Any shares subject to an option hereunder
which for any reason terminates, is cancelled or otherwise expires unexercised,
and any shares reacquired by the Corporation due to restrictions imposed on the
shares, shares returned because payment is made hereunder in stock of equivalent
value rather than in cash, and/or shares reacquired from a recipient for any
other reason shall, at such time, no longer count towards the aggregate number
of shares which have been the subject of Stock Options issued hereunder, and
such number of shares shall be subject to further awards under this 1995 Plan,
provided, first, that the total number of shares then eligible for award under
this 1995 Plan may not exceed the total specified in the first sentence of this
Section VI, and second, that the number of shares subject to further awards
shall not be increased in any way that would cause this 1995 Plan or any Stock
Option to not comply with Section 16, if applicable to the Corporation.

     SECTION VII. EFFECTIVE DATE AND TERM OF THIS PLAN.

effective date of this 1995 Plan is June 28, 1995 (the "Effective Date") and
awards under this 1995 Plan may be made for a period of ten years commencing on

                         SELLING STOCKHOLDER AGREEMENT
                         -----------------------------

     AGREEMENT, dated as of December __, 1995 (the "Agreement"), among Hologic,
Inc., a Delaware corporation (the "Company"), and each stockholder of the
Company listed on Exhibit A, attached hereto (collectively the "Selling
Stockholders").

                              W I T N E S S E T H
                              -------------------

     WHEREAS, the Board of Directors of the Company has determined that a public
offering (the "Public Offering") of the Company's Common Stock, $.01 par value
(the "Common Stock"), would be beneficial to the Company and its stockholders
and proposes to issue shares of Common Stock (the "Company Shares") for such
purpose; and

     WHEREAS, the Company also has determined that it would be beneficial to the
Company and its stockholders for certain stockholders to have the opportunity to
sell in the Public Offering a portion of the shares of Common Stock held by such
stockholders; and

     WHEREAS, the Company has offered such stockholders such opportunity and the
Selling Stockholders propose to accept such offer and sell in the Public
Offering an aggregate of up to 180,000 shares of Common Stock (the "Stockholder
Shares").

     NOW THEREFORE, in consideration of the mutual and dependent promises
hereinafter set forth and such other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

     SECTION 1.  Payment of Expenses.
                 ------------------- 

(a)  The Company shall pay (i) all of the expenses, other than underwriting
discounts, incurred in connection with the Public Offering (including, but not
limited to, all registration, filing and qualification fees, transfer agent's
fees, printing and engraving fees and legal and accounting fees), and (ii) the
Company's pro rata portion of all underwriting discounts incurred in connection
with the Public Offering, determined in accordance with the number of Company
Shares and Stockholder Shares actually sold by each respective party in the
Public Offering.

          (b)  Each Selling Stockholder shall pay such Selling Stockholder's pro
rata portion of all underwriting discounts incurred in connection with the
Public Offering, determined in accordance with the number of Company Shares and
Stockholder Shares actually sold by each respective party in the Public
Offering.

          (c)  Notwithstanding the provisions of this Section 1 or any other
agreement of the Company to pay certain expenses of the Public Offering, if the
payment of any such expenses by the Company shall be prohibited by any state
Blue Sky or securities regulatory commission in a jurisdiction in which Shares
are offered, then each Selling Stockholder agrees to pay his or its

                                       1
<PAGE>
 
pro rata portion of any such expenses determined in accordance with the number
of Company Shares and Stockholder Shares actually sold by each respective party
in the Public Offering.

     SECTION 2.  Indemnification; Contribution.
                 ----------------------------- 

          (a)  The Company shall indemnify each of the Selling Stockholders, and
each person (if any) who controls such Selling Stockholder within the meaning of

of a material fact  contained in the registration statement filed or to be filed
with the Securities and Exchange Commission (the "Commission"), in connection
with the Public Offering, as the same may be amended or supplemented from time

                                                       --------  ------- 
insofar as such losses, claims, damages, or liabilities are caused by an untrue
statement of a material fact contained in, or any material fact omitted from,
information relating to a Selling Stockholder furnished in writing to the
Company by such Selling Stockholder for use in the Registration Statement or any
amendment or supplement thereto, or any such prospectus, then the Company shall

Stockholders contained in this Section 2 shall remain in effect regardless of

circumstances in which indemnification provided for in paragraph (a) of this
Section 2 is unavailable, the Company and each of the Selling Stockholders shall
contribute to the aggregate losses, claims, damages, liabilities and expenses
(including all reasonable fees and disbursements of counsel incurred in 
defending against any claim, damage, or liability), to which one or more of the
Selling Stockholders may be subject in such proportion as is appropriate to 
reflect the relevant fault of the Company and the respective Selling 
Stockholders in connection with the statements or omissions that resulted in 
such losses, claims, damages, liabilities and expenses as well as any other
relevant equitable considerations: provided, however, that:
                                   --------  -------

               (ii)   no Selling Stockholder shall in any case be required to
contribute or make any payments under this paragraph (d) which in the aggregate
exceed his pro rata share of such losses, claims, damages, liabilities and
expenses determined in accordance with the total number of Company Shares and
Stockholder Shares sold by each respective party hereto provided, however, that,
                                                        --------  -------       
except as set forth in subparagraph (iii) of this paragraph (d), no Selling
Stockholder shall be liable to contribute an amount that exceeds the aggregate
public offering price of the Stockholder Shares sold by the Selling Stockholder,
net of the underwriting discount;

               (iii)  in the event the Company or any Selling Stockholder
defaults on its obligation to make any contribution pursuant to this paragraph
(d), the amount that each of the remaining parties is obligated to contribute
hereunder shall be increased in accordance with the relation of the number of
shares of Common Stock being sold by each such remaining party to the aggregate
number of shares of Common Stock being sold by all such remaining parties;

               (iv)   neither the Company nor any Selling Stockholder will be
required to make any contribution to another Selling Stockholder with respect to
matters for which the other Selling Stockholder would not otherwise be entitled
to be indemnified under paragraph (a) of this Section 2 had such indemnification
been available; and

               (v)    for purposes of this paragraph (d), each person, if any,
who controls a Selling Stockholder within the meaning of Section 15 of the Act,
and each director, officer or partner (if any) of such Selling Stockholder,
shall have the same rights to contribution under this Agreement as such Selling
Stockholder.

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



    This Agreement is made and entered into as of this 30th day of September,
1994 (the "Effective Date") by and between HOLOGIC, INC. ("HOLOGIC"), a Delaware
corporation with a principal place of business at 590 Lincoln Street, Waltham,
Massachusetts 02154, and SEREX, INC. ("SEREX"), a New Jersey corporation with a
principal place of business at 230 West Passaic Street, Maywood, New Jersey
07607.

    WHEREAS, SEREX has developed a proprietary technology that has applications
for diagnostic test strip markers; and

    WHEREAS, HOLOGIC is in the business of developing and marketing diagnostic
products applicable to osteoporosis and bone metabolism; and

    WHEREAS, HOLOGIC and SEREX wish to cooperate in the development and
production of a product that uses SEREX's proprietary technology to assess and

    WHEREAS, SEREX is willing to grant, and HOLOGIC desires to obtain, exclusive
rights and licenses in the product resulting from their cooperation;

    NOW, THEREFORE, in consideration of the mutual promises made herein and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties agree as follows:

    1.   DEFINITIONS

    The following terms as used in this Agreement shall have the meanings
specified below:

         (a) The term "TEST" shall mean a urine-activated test strip marker that

technology to assess bone turnover, and any IMPROVEMENT thereof.

         (b) The term "READER" shall mean one or more reader devices that are
capable of analyzing and displaying the result produced by the use of a TEST and
any IMPROVEMENT thereof.

                                      -1-
<PAGE>
 
         (c) The term "PRODUCT" shall mean the TEST and the READER.

         (d) The term "IMPROVEMENT" shall mean any modification or addition to
the TEST or READER that improves the cost, accuracy, precision, or processing
speed of such TEST or READER.

         (e) The term "PROJECT" shall mean the joint undertaking of HOLOGIC and
SEREX to develop, conduct clinical trials of, gain regulatory approval for,
manufacture, market and sell the PRODUCT.

         (f) The term "PATENTS" shall mean the patent, if any, issued in
connection with U.S. Patent Application # 08192778, and any patent application
filed in the United States or elsewhere with respect to the PRODUCT and any
patent issued thereon.

         (g)  The term "INTELLECTUAL PROPERTY" shall mean the PATENTS and all
trade secrets and other know-how relating to the design, development, and
manufacture of the PRODUCT.
  
    2.   ROLE OF THE PARTIES IN COOPERATION

    2.1  The parties jointly will devise specifications for the function,
application, utilization, accuracy, and cost of the PRODUCT.

    2.2  SEREX will conduct the development of the TEST and supervise the
development of the READER to satisfy the agreed specifications.

    2.3  HOLOGIC will design, negotiate, and conduct clinical trials of the
PRODUCT and will bear the cost of such clinical trials.  SEREX will cooperate
with HOLOGIC and provide technical assistance to effect clinical trials of the
PRODUCT.

    2.4  HOLOGIC will file for and use diligent efforts to obtain approval from
the Food and Drug Administration ("FDA") and any other relevant regulatory
authority in the United States and elsewhere in the world where HOLOGIC intends
to market and sell the PRODUCT.  Regulatory approvals will be issued in the name
of HOLOGIC, which will bear the cost of obtaining such approvals.  SEREX will
cooperate with HOLOGIC and provide technical assistance to secure regulatory
approvals of the TEST.
  
    2.5  On or before October 1st of each year following FDA approval, HOLOGIC
shall deliver to SEREX a marketing forecast for the following calendar year,
including the estimated number of TESTS HOLOGIC anticipates purchasing during
such period and any delivery requirements HOLOGIC anticipates imposing.  Within
thirty (30) days following receipt of such forecast, SEREX shall notify 
  
                                      -2-
<PAGE>
 
HOLOGIC whether it has the capacity to manufacture and deliver the estimated
number of TESTS.

    2.6  At HOLOGIC's request from time to time, SEREX will manufacture the
TESTS and design and procure the packaging for the PRODUCT. While HOLOGIC has a
present intention to have SEREX manufacture the TESTS provided SEREX can meet
the quality, quantity and delivery requirements of HOLOGIC, HOLOGIC, subject to
the provisions of Section 8 hereof, reserves to itself, in its sole and absolute
discretion, the right to purchase TESTS from third party manufacturers.

    2.7  HOLOGIC will market, distribute and sell the PRODUCT worldwide.

    3.   CONDUCT OF THE DEVELOPMENT

    3.1  It is agreed by both parties hereto that the development of the PRODUCT
under this Agreement will be conducted through mutually agreed steps and
according to a mutually agreed schedule. Within sixty (60) days after the
Effective Date, SEREX will deliver to HOLOGIC a detailed development plan based
on the proposal set forth in HOLOGIC's letter to SEREX dated June 24, 1994, a
copy of which is attached hereto as Appendix A. The proposed plan shall include
estimated costs, performance targets, a monthly budget and a schedule for
development of the PRODUCT. In the event that HOLOGIC does not agree with the
plan as proposed, the parties shall use their best efforts to develop a
development plan with mutually agreeable terms. The development plan, as finally
agreed to by the parties, shall be referred to in this Agreement as the "Plan."

    3.2  SEREX will use its best efforts to complete the development of each
step as scheduled in the Plan. In the event that SEREX does not complete a step
as set forth in the Plan or according to the schedule in the Plan, SEREX may
propose a revised Plan, provided that SEREX shall agree to bear all costs and
expenses arising from delays or deviance from the original Plan. HOLOGIC may
accept or reject a proposed revised Plan at its sole discretion.

    3.3  SEREX will assign [  *  ] persons to work full-time in the development
of the PRODUCT, and will provide all necessary materials, facilities, equipment
and other resources to support such personnel. The persons assigned to the
PROJECT may change from time to time, provided that the persons assigned at any
one time shall have the knowledge and skills appropriate to the portion of the
PROJECT on which they are working.
 
                                      -3-
<PAGE>
 
    3.4  Judith Fitzpatrick, Ph.D., founder and Chief Science Officer of SEREX,
shall serve as PROJECT Manager and agrees to devote whatever portion of her
professional efforts are necessary to ensure that the PROJECT proceeds according
to the Plan. In the event that Dr. Fitzpatrick fails to devote adequate time and
attention to the PROJECT, as determined by HOLOGIC in the reasonable exercise of
its discretion, or if Dr. Fitzpatrick ceases to be actively involved in the
PROJECT or in SEREX's business generally, HOLOGIC, in the sole exercise of its
discretion and at its own expense, may select and appoint a manager to oversee
the conduct and completion of the PROJECT.

    3.5  Not less than sixty (60) days prior to the projected date of completion
of SEREX's development of the PRODUCT, as estimated by the parties from time to
time, HOLOGIC shall deliver to SEREX a plan for the clinical trials of the
PRODUCT. The proposed plan shall include a description of the manner in which
the trials will be conducted, as well as an estimated schedule for such trials.
HOLOGIC agrees to use its best efforts to conduct the clinical trials
substantially in accordance with the proposed plan.

    3.6  At least fifteen (15) days prior to submitting any filing to the FDA or
any other regulatory authority pursuant to Section 2.4, above, HOLOGIC shall,
prior to submission to the FDA, provide copies of the proposed filings (together
with English translations thereof, where necessary) to SEREX for review and
comment. The final form and contents of any such filing shall be determined by
HOLOGIC in the sole exercise of its discretion.

    4.   COSTS AND EXPENSES

    4.1  HOLOGIC shall reimburse SEREX for the expenses incurred by SEREX to
develop the PRODUCT, not to exceed the sum of [   *   ] for any one month;
provided, however, that the maximum amount of expenses for which reimbursement
is required shall be reduced to [  *  ] per month upon the commencement of
clinical trials of the TEST (as confirmed by first patient enrollment) and shall
be reduced to [  *  ] upon the first commercial sale of the PRODUCT.  As used
herein, the term "expenses" shall mean expenses incurred in connection with this
Agreement (even if incurred prior to the Effective Date), salaries and benefits
allocable to the portion of any employee's time spent on the PROJECT, costs of
materials, travel costs specifically related to the PROJECT, and costs of
maintaining and operating laboratory and other facilities used for the PROJECT.
The term "expenses" shall not include any attorneys fees or 

                                      -4-
<PAGE>
 
other legal expenses incurred by SEREX in connection with the negotiation,
execution, or enforcement of this Agreement.

    4.2  Reimbursement required pursuant to Section 4.1 shall be provided as
follows:

         a.   HOLOGIC shall pay SEREX the sum of [   *   ] upon the execution of
              this Agreement;

         b.   HOLOGIC shall pay SEREX the sum of [   *   ] ninety (90) days
              after the Effective Date;

         c.   HOLOGIC shall pay SEREX the lesser of SEREX's projected expenses
              for the then-current calendar quarter or [   *   ] ([   *   ],
              after the commencement of clinical trials of the TEST) on or
              before the one hundred eightieth day following the Effective Date
              and on or before the same day of each third month thereafter, but
              in no event sooner than five (5) days after HOLOGIC's receipt of
              SEREX's most recent monthly report due pursuant to Section 6.1,
              below, in each case minus any amount by which the previous payment
              exceeded the actual expenses incurred by SEREX.

    5.   OPTION TO ADD THIRD PARTY

    For a period of ninety (90) days after the Effective Date, HOLOGIC reserves
the right, and SEREX grants HOLOGIC the option, to identify a third party to
assist in and expedite biochemical research for development of the TESTS. If
HOLOGIC identifies such a third party and the identified party is acceptable to
SEREX (such acceptance not to be unreasonably withheld or delayed), then
HOLOGIC, SEREX, and the third party shall use their best efforts to negotiate
their respective rights and obligations in the development of the PRODUCT, which
negotiation may result in the execution of an agreement mutually acceptable to
both parties that modifies or supersedes this Agreement.

    6.   REPORTS AND MEETINGS

    6.1  The PROJECT Manager shall conduct a formal PROJECT review not less
frequently than once per month. On or before the 15th of each month, SEREX will
furnish a written report to HOLOGIC that describes the progress of the
development effort as of the end of the preceding calendar month, including the
status of the PRODUCT, the actual costs incurred to date, the proposed

                                      -5-
<PAGE>
 
work for the next one- and three-month periods, the projected costs of the next
one- and three-month periods, and any other information reasonably requested by
HOLOGIC.

    6.2 SEREX shall keep true and accurate records, files, and books of account
containing all the data reasonably required for the full computation and
verification of costs and expenses to be reimbursed under this Agreement or of
income on which reimbursement of amounts due under Section 13.8, if applicable,
are to be computed. Such materials shall be retained for a period of at least 5
years following the end of the fiscal year to which they relate. SEREX's books
of account shall be maintained in accordance with generally accepted accounting
principles consistently applied. SEREX shall permit the reasonable inspection
and copying of such records, files, and books of account by HOLOGIC or its
representatives during regular business hours at SEREX's regular place of
business, provided that HOLOGIC shall give SEREX at least 7 days prior written
notice of its election to inspect such records, files, and books of account.
Fees and expenses incurred in connection with such inspections (including, but
not limited to, professional fees and expenses paid to accountants or other
examiners retained by HOLOGIC and the cost of copying records, files, and books
of account) shall be borne by HOLOGIC, unless such inspection shall reveal that
an error in the amount of five percent (5%) or more of the aggregate amount of
expenses for any month was made, in which case the fees and expenses incurred in
connection with the inspection during which such error was discovered shall be
borne by SEREX.

    6.3  HOLOGIC and SEREX shall meet at least once every three months, or more
frequently as the need may arise, at such times and places as mutually agreed in
order to render the technical cooperation most effective and desirable to both
parties.

    7.   LICENSING AND DISTRIBUTION

    7.1  SEREX hereby grants HOLOGIC the exclusive right and license, with the
right to grant sublicenses to others, to use the INTELLECTUAL PROPERTY to
manufacture, market, sell, and distribute the PRODUCT worldwide, in all markets
and for all applications, directly or through such contractors, agents,
distributors, licensees, sublicenses or representatives as HOLOGIC may appoint.

                                      -6-
<PAGE>
 
    7.2  In the event that SEREX conceives a new product (not including an
IMPROVEMENT) with applications in bone metabolism, SEREX shall provide HOLOGIC
with a description of such product and with all information available to SEREX
regarding the design, development, application of, or market for such product.
If HOLOGIC notifies SEREX of its interest in such product within thirty (30)
days following receipt of such information, the parties shall negotiate in good
faith the terms of an agreement governing the development and distribution of
such product. In the event that SEREX and HOLOGIC do not agree to the terms of
such an agreement within ninety (90) days following HOLOGIC's notice of its
interest to SEREX, SEREX may, at its option, negotiate a development and
distribution agreement with another party, provided that SEREX may not enter
into an agreement with any third party on more favorable terms to such third
party than SEREX has offered to HOLOGIC.

    7.3  To maintain its exclusive rights pursuant to Section 7.1, HOLOGIC is
required to purchase from SEREX or any third party manufacturer, in the
aggregate, at least the minimum number of TESTS specified below in the [   *   ]
commencing 90 days after the issuance of a patent on the application filed
pursuant to Section 10.2, below:

    (a)  [     *     ] - [   *   ] TESTS
    (b)  [     *     ] - [   *   ] TESTS
    (c)  [     *     ] - [   *   ] TESTS
    (d)  [     *     ] - [   *   ] TESTS
    (e)  [     *     ] - [   *   ] TESTS

If HOLOGIC fails to purchase the minimum number of TESTS for any year, then
SEREX may elect, upon sixty (60) days advance notice to HOLOGIC (which notice
must be given within ninety (90) days following the end of such year), to make
HOLOGIC's license and distribution rights nonexclusive, unless HOLOGIC, within
such 60-day period, agrees to pay SEREX an amount equal to the difference
between the amount actually paid pursuant to Section 8 and the amount that would
have been payable if HOLOGIC had purchased the minimum number of TESTS.

    8.  PAYMENTS

    8.1  In consideration of the rights granted to HOLOGIC under this Agreement,
HOLOGIC shall pay SEREX for each TEST purchased, whether from SEREX or a third
party manufacturer, according to the following schedule:

                                      -7-
<PAGE>
 
         (a)  [           *           ] TESTS purchased, [  *  ] per TEST

         (b)  [           *           ] TESTS purchased, [  *  ] per TEST;

         (c)  [     *     ] or more TESTS purchased, the lesser of [   *   ] per
              TEST or manufacturing cost plus [   *   ] [ * ]  per TEST,

provided that, for any year in which HOLOGIC purchases [      *      ] TESTS or
more, the price of all TESTS purchased shall be computed in accordance with
subparagraph (c), above.

    8.2  In the event that HOLOGIC exercises its right to purchase the TESTS
from a third party manufacturer, as set forth in Section 2.6 hereof, the payment
due to SEREX shall be reduced by the amount paid to the third party, provided
that, in the event that SEREX had the capacity to produce at least the number of
TESTS HOLOGIC notified SEREX it planned to purchase during the year (as provided
in Section 2.5 of this Agreement), the amount due to SEREX shall not be reduced
pursuant to this paragraph below the following amounts:

         (a)  [   *   ] on the first [    *    ] TESTS, provided subparagraph
              (b) does not apply;

         (b)  [   *   ] on all TESTS in excess of [    *    ] and on all TESTS
              purchased in a year in which HOLOGIC purchases [    *    ] TESTS
              or more.

Payments, if any, required to be made by HOLOGIC to SEREX pursuant to this
Section 8.2 shall be made quarterly together with the report to be submitted to
SEREX under Section 8.6 hereof.

    8.3  In the event that HOLOGIC is entitled to a refund as a result of the
recalculation of the payments pursuant to Section 8.1 or 8.2(b) in a year in
which more than [    *    ] TESTS are purchased, such refund shall be credited
against payments next due from HOLOGIC, provided that, at HOLOGIC's option,
SEREX shall make a cash payment to HOLOGIC with respect to 
  
                                      -8-

any refund not applied within six (6) months from the date first due to HOLOGIC.

    8.4  The payments specified in Section 8.1(a) and (b) and the [ * ] maximum
payment specified in Section 8.1(c) may be adjusted one year after FDA approval
for marketing of the PRODUCT is obtained, to reflect the change between the
value of the Consumer Price Index at the time FDA approval was granted and the
value of said Index one year later, provided that that the above-referenced
payments shall not be increased or decreased by more that [      *      ] of the
original prices.

    8.5  The "manufacturing cost" of the TESTS, for purposes of determining the
price due to SEREX pursuant to Section 8.1(c), shall be SEREX's direct costs of
materials and personnel expended on the fabrication, quality control, and FDA
documentation of the TESTS, plus a pro rata portion of SEREX's manufacturing
overhead based on the portion of SEREX's manufacturing resources allocated to
the manufacture of the TESTS, as confirmed by independent audit.

    8.6  HOLOGIC shall keep true and accurate records, files, and books of
account containing all the data reasonably required for the determination and
verification of the number of TESTS purchased by it, on which the amount due to
SEREX under Section 8.2 hereof is to be computed, and shall submit a report to
SEREX within 45 days after the end of any calendar quarter in which HOLOGIC
purchases TESTS from a third party manufacturer, which report shall set forth
the number of TESTS purchased and a calculation of payments due SEREX under
Section 8.2.  Such materials shall be retained for a period of at least 5 years
following the end of the fiscal year to which they relate.  HOLOGIC's books of
account shall be maintained in accordance with generally accepted accounting
principles consistently applied.  HOLOGIC shall permit the reasonable inspection
and copying of such records, files, and books of account by SEREX or its
representatives during regular business hours at HOLOGIC's regular place of
business, provided that SEREX shall give HOLOGIC at least 7 days prior written
notice of its election to inspect such records, files, and books of account.
Fees and expenses incurred in connection with such inspections (including, but
not limited to, professional fees and expenses paid to accountants or other
examiners retained by SEREX and the cost of copying records, files, and books of

                                      -9-

account) shall be borne by SEREX, unless such inspection shall reveal that an
error in the amount of five percent (5%) or more of the aggregate amount paid to
SEREX in any quarter was made, in which case the fees and expenses incurred in
connection with the inspection during which such error was discovered shall be
borne by HOLOGIC.

    9.   CONFIDENTIALITY

    9.1  Each party shall hold in strict confidence and shall cause each of its
officers, directors, employees, and agents to hold in strict confidence any and
all proprietary information that may be disclosed to such party by the other
party, which information shall be identified by the disclosing party as being
confidential, in writing, at the time of the disclosure or, in the event the
disclosure is made orally, within thirty (30) days thereafter.

    9.2  Each party understands that the obligation of nondisclosure set forth
in Section 9.1 above shall not apply to any information that:

         (a)  at the time of the disclosure, is freely available to the general
              public or that has been identically disclosed in published
              literature or patents, provided that no combination of features
              shall be deemed to be within this exception merely because its
              component features are freely available to the general public or
              have been disclosed in published literature or patents, but only
              if the combination itself and its principles of operation are
              freely available to the general public or disclosed in published
              literature or patents;

         (b)  is or has become generally known to the public through no fault of
              the receiving party,

         (c)  the receiving party can reasonably show is already known to it or
              independently developed by it,

         (d)  is received by the receiving party without restriction from a
              third party who has a right to disclose the same,

         (e)  is required to be disclosed by a government authority or by order
              of a court of competent jurisdiction, provided that such
              disclosure is subject to all applicable governmental and judicial
              protection available for like material, or

                                      -10-
<PAGE>
 
         (f)  is approved for release to a third party by the prior written
              authorization of the disclosing party.

    9.3 Each party will take whatever action is necessary or appropriate to
ensure that its employees, officers, and directors comply with the provisions of
this Section 9 both during and after the time they serve in such capacities. In
the event that any such individual makes an unpermitted disclosure of any
confidential information hereunder, the party with which such individual is
affiliated shall promptly take whatever action is necessary or appropriate to
minimize the adverse effect of such disclosure.

    9.4  The parties understand and agree that any breach of the obligation of
confidentiality expressed in this Section 9 may cause irreparable damage to the
business and property of the nondisclosing party. In the event of any such
breach or of the substantial likelihood that such a breach will occur, the
disclosing party understands that the other party may take legal action,
including seeking injunctive relief, to protect its interests and property. The
disclosing party hereby consents to the entry of an injunction in such
circumstances to enjoin the disclosure.

    9.5  Notwithstanding the foregoing provisions of this Section 9, each party
may disclose to a third party to be engaged in the PROJECT for such party any
information of the other party to the extent that such information is necessary
for such third party's involvement, provided, however, that prior to any such
disclosure, the third party shall have executed a confidentiality agreement,
substantially in the form attached hereto in Appendix B, agreeing to maintain
the confidentiality of such information.

    10.  INTELLECTUAL PROPERTY RIGHTS

    10.1 Ownership of the INTELLECTUAL PROPERTY shall reside with the party
employing the employee or agent who creates or invents the property in
connection with the development contemplated hereunder; provided however, that
if an invention or device shall have been jointly made by the employees or
agents of both HOLOGIC and SEREX, then HOLOGIC and SEREX shall jointly own any
INTELLECTUAL PROPERTY associated with such joint invention or device.

    10.2 SEREX agrees to file an application for a United States patent on the
Serex Antibody Release Assay immuno-diagnostic technology as it applies to
osteoporosis within six (6) months following the Effective Date.
  
                                      -11-
<PAGE>
 
    10.3 All expenses and charges necessary for filing applications for
registration and maintenance fees of any intellectual property right shall be
borne by the party that owns such intellectual property right. All such expenses
and charges arising in connection with any intellectual property right to be
jointly owned by HOLOGIC and SEREX shall be equally borne by HOLOGIC and SEREX.
Notwithstanding the preceding sentence and except as agreed by SEREX pursuant to
Section 10.2, above, neither party shall be obligated to apply for registration
of any intellectual property right owned, in whole or in part, by it if such
party determines, in the reasonable exercise of its business judgment, that such
registration is not necessary or would not be cost effective. If the party
owning such rights (the "OWNER") elects not to register an intellectual property
right, and the other party (the "ASSIGNEE") would have exclusive or nonexclusive
license to exercise the inventions or devices to which such rights pertain, the
ASSIGNEE, at its own expense, may register such intellectual property rights in
the OWNER's name in such countries as it deems necessary or appropriate and the
OWNER will assign its rights in such registration to the ASSIGNEE. No assignment
pursuant to this provision shall negate or otherwise limit the ASSIGNEE's
obligation, if any otherwise exists, to pay royalties to the OWNER with respect
to the intellectual property rights that are the subject of the assigned
registration nor shall any such assignment negate or otherwise limit the OWNER's
rights to use such intellectual property rights.

    10.4 The name "Hologic" or HOLOGIC's trademark may be used in connection
with the PRODUCT only with advance written consent of HOLOGIC and, if so used,
creates and confers no right in such name or trademark upon SEREX.

    11.  INDEMNIFICATION

    11.1 HOLOGIC agrees to indemnify and hold SEREX and its officers, directors,
employees, licensees, and agents harmless from and against any liabilities,
costs, or other damages (including reasonable attorneys fees and litigation
costs, regardless of outcome) arising out of a breach of one or more of
HOLOGIC's representations or warranties expressed in Section 15 of this
Agreement, provided SEREX shall have taken reasonable actions to minimize such
liabilities, costs, or other damages and provided, further, that SEREX has
complied with the procedures set forth in subsection 11.4, below. HOLOGIC shall
use its best efforts to have SEREX identified as a third party

                                      -12-
<PAGE>
 
beneficiary of any contractual right to indemnification that HOLOGIC secures
from a third party manufacturer of the PRODUCT.

    11.2 SEREX agrees to indemnify and hold HOLOGIC and its officers, directors,
employees, licensees, and agents harmless from and against any liabilities,
costs, or other damages (including reasonable attorneys fees and litigation
costs, regardless of outcome) arising out of the design, manufacture by SEREX,
use, or sale of the PRODUCT or of any improvements or alterations thereto,
provided that no such damages are the result of a use, application, or written
warranty authorized by HOLOGIC without the knowledge of SEREX, or from a breach
of any one or more of SEREX's representations or warranties expressed in Section
15 of this Agreement, provided HOLOGIC shall have taken reasonable actions to
minimize such liabilities, costs, or other damages and provided, further, that
HOLOGIC has complied with the procedures set forth in subsection 11.4, below.

    11.3 Each party (the "Indemnifying Party") agrees to indemnify and hold the
other party (the "Indemnified Party") and such other party's officers,
directors, employees, licensees, and agents harmless from and against any
liabilities, costs, or other damages (including reasonable attorneys fees and
litigation costs, regardless of outcome) arising out of the infringement of any
third party's intellectual property rights by the intellectual property owned by
the Indemnifying Party, provided the Indemnified Party shall have taken
reasonable actions to minimize such liabilities, costs, and other damages and
provided, further, that the Indemnified Party has complied with the procedures
set forth in subsection 11.4, below.

    11.4 If any claim, action, or other legal proceeding is asserted against a
party for which such party may have a right to indemnification pursuant to this
Section 11, such party (the "Indemnified Party") shall give the other party (the
"Indemnifying Party") prompt written notice of such claim or proceeding and the
Indemnifying Party may elect to control the defense to or settlement of such
dispute.  In the event that the Indemnified Party cannot reasonably anticipate
that the Indemnifying Party will receive notice of such claim or proceeding at
least 20 days prior to the date by which any action needs to be taken to
preserve and protect the parties' rights, the Indemnified Party shall take such
action on behalf of the Indemnifying Party.  The Indemnified Party shall
cooperate with the Indemnifying Party in any defense 
 
                                     -13-
<PAGE>
 
or settlement made by the Indemnifying Party. The Indemnified Party shall not
enter into any settlement agreement or other voluntary resolution of any such
claim or proceeding without obtaining the Indemnifying Party's prior written
consent thereto.

    12.  INFRINGEMENT

    12.1 If HOLOGIC or SEREX becomes aware that any INTELLECTUAL PROPERTY is
being or may be infringed by a third party, the party who learns of or suspects
such infringement shall promptly notify the other party thereof. SEREX may at
its own expense prosecute any action it deems necessary to protect the rights of
each of the parties to the PRODUCT under this Agreement. If, upon inquiry by
HOLOGIC, SEREX does not initiate any such action or confirm that it intends to
do so promptly and in a timely fashion, HOLOGIC may initiate such an action in
its own behalf. If either party initiates an action pursuant to this Section 12
and recovers damages or lost profits or both as a result thereof, the recovering
party may retain the entire amount of such recovery.

    12.2 In any action prosecuted, defended, or resolved by either party
pursuant to this Section 12, the other party shall provide such assistance as
may be reasonably necessary or appropriate and shall be entitled to
noncontrolling participation at its own expense, through counsel of its own
selection.

    13.  TERM AND TERMINATION

    13.1 This Agreement shall remain in effect from the date first written
above until the first anniversary of the Effective Date that occurs after the
expiration of all PATENTS or until terminated by mutual agreement of the parties
or otherwise as provided by law or as permitted in this Section 13.

    13.2 This Agreement may be terminated by HOLOGIC, without cause, effective
on a date stated in a notice of termination given to SEREX by HOLOGIC. If
HOLOGIC terminates this Agreement pursuant to this Section 13.2 and such
termination takes place after the expiration of the 90-day option period
specified in Section 5 of this Agreement, HOLOGIC shall pay SEREX's development
expenses for the PROJECT for the three (3) months following the date of
HOLOGIC's notice of termination. If HOLOGIC terminates the Agreement pursuant to
this Section 13.2 after the first commercial sale of the PRODUCT

                                      -14-
<PAGE>
 
in the United States, the effective date of termination shall be at least ninety
(90) days after the date on which notice of termination is given.

    13.3 This Agreement may be terminated by either party for material defaults
of the other party, effective immediately upon giving notice of such termination
to the other party, provided that (i) the terminating party shall have given the
defaulting party notice of the occurrence and nature of the default at least
thirty (30) days prior to the notice of termination and (ii) the defaulting
party shall have failed to cure the default during such 30-day period and shall
have failed to initiate action during such 30-day period that is reasonably
calculated to cure the default as promptly as practical.

    13.4 This Agreement may be terminated by either party, effective immediately
upon giving notice to the other party, in the event that (i) proceedings are
instituted by such other party in bankruptcy, reorganization, receivership, or
dissolution; or (ii) proceedings are instituted against such other party in
bankruptcy, reorganization, receivership, or dissolution and such proceedings
have not been dismissed or otherwise terminated within sixty (60) days following
the date they were initiated; or (iii) such other party is generally unable to
pay its debts as they come due in the ordinary course of business or makes an
assignment for the benefit of creditors.

    13.5 This Agreement may be terminated by HOLOGIC, effective immediately upon
giving notice to SEREX, in the event that (i) the PROJECT deviates materially
and adversely from the Plan, provided that HOLOGIC has given SEREX at least 30
days' prior notice of its intention to terminate hereunder and SEREX has not,
during such 30 days, either satisfied HOLOGIC that the PROJECT is proceeding in
accordance with the Plan or proposed a revised Plan that is acceptable to
HOLOGIC; or (ii) a United States patent is not issued to SEREX pursuant to U.S.
Patent Application # 08192778 within one (1) year following the Effective Date.

    13.6 In the event of termination by HOLOGIC pursuant to Section 13.4,
HOLOGIC may, in the sole exercise of its discretion, elect to purchase all of
SEREX's rights in the PRODUCT, including all intellectual property rights
relating to processes, devices, know-how, technology, formulae, or other
components of the PRODUCT (but not including the Serex Antibody Release Assay
technology or other technology developed by SEREX and documented prior to the
Effective Date ("Existing Technology")) and to purchase a perpetual,

                                     -15-
<PAGE>
 
nonexclusive license to use the Existing Technology to complete the development
and commercialization of the PRODUCT (including manufacturing, marketing,
distributing, selling, and using the PRODUCT). In the event that HOLOGIC
exercises its rights pursuant to this Section 13.6, HOLOGIC shall pay SEREX the
amount of [   *   ] in cash or, at HOLOGIC's option, in unregistered shares of
HOLOGIC's common stock, which shares shall be subject to a limited right of
registration under the same terms as are set forth in Section 7.12 of the
"Preferred Stock Purchase Agreement" dated as of September 30, 1994 between
HOLOGIC and SEREX. SEREX shall execute such bills of sale, assignments,
representations regarding compliance with state and federal securities laws, and
other documents as HOLOGIC shall reasonably request.

    13.7 In the event that HOLOGIC terminates this Agreement pursuant to Section
13.3, 13.4 (provided HOLOGIC does not elect to exercise its rights pursuant to
Section 13.6), or 13.5, SEREX shall reimburse HOLOGIC for [      *     ] of the
amounts paid by HOLOGIC pursuant to Section 4 of this Agreement by remitting to
HOLOGIC, at the end of each calendar quarter, [     *     ]of the net sales,
royalties, license fees, and other income derived from the PRODUCT or any
device, process, know-how, technology, or other item developed in the course of
the PROJECT.

    13.8 Notwithstanding anything to the contrary contained in this Agreement,
HOLOGIC may continue to market, distribute, and sell PRODUCT then in inventory
or for which purchase orders have been issued, for a period of ninety (90) days
following the effective date of termination of this Agreement.

    13.9 Sections 9, 10, 11, 13, 16, and 17 shall survive termination of this
Agreement. In the event that HOLOGIC terminates this Agreement and is entitled
to reimbursement from SEREX pursuant to Section 13.7, Section 6.2 shall also
survive termination of this Agreement.

    14.  INVOLVEMENT OF THIRD PARTIES

    Following the option period set forth in Section 5, either party may retain
the services of one or more third parties to assist it in the performance of its
obligations under this Agreement, provided that the party to this Agreement
retains ultimate responsibility for the full and satisfactory performance of its
obligations hereunder.

              Board of Directors of SEREX to enter into this Agreement; and

         (d)  this Agreement does not violate the terms of any agreement, order,
              stipulation, understanding, or other arrangement to which it is
              subject or by which it is bound.

SEREX gives no warranty or representation, express or implied, except as
specifically stated herein.

    15.2 HOLOGIC hereby represents and warrants to SEREX that:

         (a)  it has the full authority to enter into this Agreement without the
              prior consent, concurrence, or other authorization of any court,
              agency, or other third party;

         (b)  the undersigned officer has the full authority and approval of the

              stipulation, understanding, or other arrangement to which it is
              subject or by which it is bound.

HOLOGIC gives no warranty or representation, express or implied, except as
specifically stated herein.

    16.  LIMITATIONS ON LIABILITY

    Except as expressly provided in Section 11, neither party shall be liable to
the other party under any theory of liability (including negligence) for any
indirect, special or consequential damages of any kind, or for any lost

                                     -17-
<PAGE>
 
profits or opportunities, even if the party that might be liable was advised of
the possibility of such damage.

    17.  INSURANCE

    SEREX shall procure and maintain, at its sole cost and expense, liability
insurance with a reputable and financially sound insurance carrier or carriers
against liability and claims for injuries to persons (including injuries
resulting in death) and property damage in a combined single limit of not less
than $1,000,000.00 per occurrence, and any additional insurance as may be
required by applicable laws or regulations, and shall furnish to HOLOGIC written
certificates obtained from each insurance carrier showing that insurance has
been procured and is properly maintained, that the premiums therefor are paid,
and specifying the name of the insurance carrier, the policy number or numbers,
and the expiration date or dates. At least thirty (30) days prior written notice
of any cancellation or modification of any such policy shall be given to
HOLOGIC.

    18.  SERIOUS INJURIES; PRODUCT RECALL; CORRECTIVE ACTION

    18.1 Each party shall advise the other, by confirmed facsimile, within
twenty-four (24) hours after the notifying party becomes aware of any serious
injury from the use or malfunction of the PRODUCT. The notifying party shall
include in the notification all information known to it, including (but not
limited to) the name, address, and telephone number of the person or entity that
purchased the PRODUCT in question, the name, address, and telephone number of
the patient (if different), and the lot or serial number of the TEST or READER
involved in the incident, as appropriate.

    18.2 If either party believes that a recall of any PRODUCT is necessary or
appropriate, it will promptly notify the other party. The parties will then
discuss reasonably and in good faith whether such recall is necessary or
appropriate (unless such recall is required by law) and the manner in which any
agreed or required recall shall be conducted. If a recall is not required by law
and the parties cannot agree whether or not the recall is necessary or
appropriate, either party may elect to conduct the recall in question. The
parties shall cooperate with each other in conducting any recall pursuant to
this Section. All out-of-pocket costs of a required or agreed recall, except the
printing and mailing costs incurred to notify customers of such recall, shall be
borne by SEREX. All costs of a recall to which the parties have not

                                     -18-
<PAGE>
 
agreed shall be borne by the party that elects to conduct the recall, provided
that, if a court of competent jurisdiction determines that any PRODUCTS recalled
by HOLOGIC were defective or in violation of any applicable law, SEREX shall
reimburse HOLOGIC for all reasonable out-of-pocket costs and expenses of such
recall (except for the mailing and printing costs incurred to notify customers
of such recall). HOLOGIC shall maintain complete and accurate records of all
PRODUCTS sold by it, for such periods as are required by law. Nothing contained
in this Section 18 shall be construed to modify or limit the legal obligations
of either party with respect to any recall that is required by law.

    18.3 In the event that any governmental agency having jurisdiction shall
request or order any corrective action with respect to any PRODUCTS, including
(but not limited to) any recall, customer notice, restriction, change, market
action, or any modification of the PRODUCT, and the cause or basis of such
corrective action is primarily attributable to a condition, fact, or action that
constitutes a breach by SEREX of any of its warranties, representations,
obligations, or covenants contained herein or that SEREX knew or should have
known would require such corrective action, then SEREX shall be liable for, and
shall pay or reimburse HOLOGIC for, all costs incurred by HOLOGIC as a result of
such action, including the replacement cost of any PRODUCT affected thereby.

    19.  FORCE MAJEURE

    Neither party shall be responsible for failure or delay to comply with this
Agreement, if such failure or delay is caused by fire, flood, strikes, labor
disputes or other industrial disturbances, unavoidable accidents, war, riots,
civil commotion, embargoes, prohibition of exportation, governmental direction,
intervention of civil, naval, or military authorities, or any other causes
beyond the control of the party. In such case, performance by such party of this
Agreement, other than the obligation to make payments, shall be suspended
without liability to the extent performance is affected and for the period of
delay reasonably attributable to such causes, including, without limitation,
time for recovery from such causes.

    20.  ASSIGNMENT

    Prior to the first commercial sale of the PRODUCT in the United States,
neither party may assign its rights (through contractual assignment, merger,

                                     -19-
<PAGE>
 
consolidation, sale of assets, stock or otherwise), or delegate its obligations
under this Agreement to a third party, unless the assigning or delegating party
obtains the prior written consent of the other party to this Agreement (which
consent shall not be unreasonably withheld or delayed). Notwithstanding the
foregoing and without the consent of SEREX, HOLOGIC may assign any and all
rights and delegate any and all duties under this Agreement at any time during
the term of this Agreement to (a) an entity that is owned or controlled by
HOLOGIC or by the person or persons who own or control HOLOGIC or that owns or
controls HOLOGIC or (b) the purchaser of all or substantially all of HOLOGIC's
business relating to bone metabolism diagnostic products. SEREX shall be
provided with prompt written notice of any such permitted assignment or
delegation by HOLOGIC. Any assignment, delegation, sale, or other transfer by
either party other than as expressly permitted in this Section 20 shall be null
and void.

    21.  DISPUTE RESOLUTION

    21.1 The parties shall attempt in good faith to resolve all disputes that
may arise during the term of this Agreement or thereafter promptly by
negotiation between executives who possess the authority to settle such dispute.
Either party may give the other written notice of any dispute not resolved in
the ordinary course of business. Within fifteen (15) days after delivery of the
notice, the receiving party shall forward a written response to the disputing
party. The notice and the response shall include (a) a brief statement of each
party's position, and (b) the name and title of the executive who will represent
that party in negotiations. Within thirty (30) days after delivery of the
disputing party's notice, the executives of both parties shall meet at a
mutually acceptable time and place, and again thereafter as they reasonably deem
necessary, to exchange relevant information and to attempt to resolve the
dispute. All reasonable requests for information by one party to the other will
be honored. All negotiations pursuant to this Section are confidential and shall
be treated as compromise and settlement negotiations for evidentiary purposes.

    21.2 If the dispute has not been resolved within sixty (60) days after
delivery of the disputing party's notice, the dispute shall be submitted to
arbitration under the then prevailing rules of the American Arbitration

                                     -20-
<PAGE>
 
Association for commercial arbitration. The place of arbitration shall be
Boston, Massachusetts. The award of arbitration shall be final and binding.

    22.  COMPLIANCE WITH LAWS; GOVERNING LAW

    22.1 The parties agree to conduct their efforts pursuant to this Agreement
in compliance with all applicable statutory and regulatory requirements,
including making information available to each other that is required in order
to comply with the parties' respective regulatory reporting requirements. The
parties agree to comply with all health registration laws, regulations, and
orders applicable to the development, manufacture, marketing, distribution, and
sale of the PRODUCT.

    22.2 This agreement shall be governed by and construed in accordance with
the laws of the Commonwealth of Massachusetts, without reference to any
conflicts of laws provisions.

    23.  NOTICE

    Any notice or other communication required or permitted under this Agreement
shall be sufficiently given, unless specifically required to be given in some
other manner pursuant to the terms of this Agreement, if (a) delivered by hand;
or (b) sent by Federal Express or other overnight carrier; or (c) sent by
