ITEM 1.   BUSINESS

     Metra is a leader in developing and commercializing diagnostic products 
for the detection and management of metabolic bone diseases and disorders. 
The Company's strategy is to offer a portfolio of diagnostic products that 
will provide physicians with comprehensive clinical information regarding the 
metabolism of bone and other connective tissues. The Company has developed 
and is currently marketing for either research use or clinical use two 
immunodiagnostic tests to measure bone resorption (loss), two 
immunodiagnostic tests to measure bone formation and one immunodiagnostic 
test to measure bone growth disorders. In addition, the Company is currently 
developing a portable ultrasound device designed to assess bone fragility, a 
simple bone-resorption test for use in the physicians offices and biochemical 
markers to detect cartilage disorders. Since August 1995, the Company has 
received 510(k) clearances for commercial sale of the following 
immunodiagnostic tests: Alkphase-B in August 1995, Pyrilinks in November 1995 
and Pyrilinks-D in December 1995. In addition, the Company has entered into 
several collaborative arrangements with major pharmaceutical and diagnostic 
companies, including a worldwide marketing collaboration with Wyeth-Ayerst 
Laboratories, a division of American Home Products, in November 1995 and, in 
February 1996, a collaboration with Abbott Laboratories to format the 
Company's products for Abbott's automated immunoassay systems. 

BACKGROUND

     The human body and its major organs are supported and protected by a 
matrix of connective tissues. Major connective tissue systems in the body 
include bone, cartilage, tendons and skin. Connective tissues primarily 
consist of the extracellular matrix, which is composed of a variety of 
proteins. Connective tissue diseases and disorders usually result from 
excessive production or breakdown of this extracellular matrix. 

     The body's principal connective tissue systems are bone and cartilage. 
Although the two systems are distinct, they have a similar underlying 
biology. Major diseases and disorders affecting bone and cartilage include 
osteoporosis, Paget's disease, cancers that metastasize to bone, 
hyperthyroidism, hyperparathyroidism, growth hormone deficiency, rheumatoid 
arthritis, and osteoarthritis. Many of these diseases and disorders can be 
disabling, can affect the quality of life, and can eventually lead to death. 

  BONE BIOLOGY

     Bone is a dynamic tissue that continually regenerates and remodels 
itself throughout an individual's life. This remodeling process, which 
consists of bone formation and resorption (loss), is ongoing and is necessary 
to maintain skeletal integrity. Clinical studies suggest that 


                                       3


<PAGE>


between 10% and 20% of the adult skeleton is replaced each year by the 
remodeling process. From childhood to early adulthood, bone formation exceeds 
resorption, causing bone mass to increase. Typically, after reaching peak 
bone mass between the ages of 30 and 40, bone resorption begins to exceed 
formation, and both men and women experience a slow, age-related phase of 
bone loss, lasting for the rest of their lives. In addition to age-related 
bone loss, most women also experience an accelerated phase of bone loss for 
several years following menopause, primarily due to the cessation of estrogen 
production. 

     Bone remodeling is a complex process involving bone resorption, in which 
cells called "osteoclasts" excavate small pits throughout the bone, followed 
by bone formation, in which cells called "osteoblasts" produce and deposit 
bone collagen to fill the pits excavated by the osteoclasts. The remodeling 
process takes place continuously throughout the skeleton, at multiple 
locations and in different phases at the same time. At the beginning of a 
remodeling cycle at a particular location, osteoclast precursor cells in the 
bone marrow are recruited and migrate to the targeted area of bone. These 
cells fuse to form osteoclasts and, over a period of one to three weeks, the 
osteoclasts erode away bone in the targeted area. The osteoclasts are 
replaced by osteoblasts during the next phase of the cycle, which then fill 
in the resorption cavities with mineralized collagen over a period of three 
to four months to create new bone. The osteoclastic and osteoblastic 
processes produce fragments of collagen and other proteins, which are 
released into the bloodstream and eventually appear in other bodily fluids, 
including urine.

     In general, the bone resorption and formation processes are tightly 
coupled and balanced. When this tightly balanced remodeling process becomes 
unbalanced or exaggerated, bone disease ensues. In addition, there are a 
number of drugs or medications, including those used to treat patients with 
endometriosis, asthma, organ transplants, cancer, arthritis, thyroid 
disorders and patients with renal failure, that can have an adverse side 
effect of stimulating excessive bone loss. 

OSTEOPOROSIS

     The most widespread bone disease is osteoporosis, a disorder 
characterized by a decrease in bone mass that leads to increased 
susceptibility to fractures, particularly those of the hip, spine and wrist. 
There are two major types of osteoporosis. The most common type is primary 
osteoporosis, which includes post-menopausal osteoporosis, resulting from an 
estrogen deficiency in women, and senile osteoporosis, an age-related 
condition primarily affecting men and women over age 75. Secondary 
osteoporosis occurs as a side effect of medication, or as a consequence of 
another disease that causes a decrease in bone mass. 

     Osteoporosis is often called the "silent disease" because bone loss 
itself causes no physical symptoms. In many cases, doctors and patients are 
not aware of the problem until many bones in the skeletal system have become 
so weak that a sudden strain, bump or fall causes a fracture. If diagnosed 
early enough, the rate of bone loss can be reduced using one or a combination 
of drug therapies. Consequently, diagnosis of bone loss and preventive 
intervention is important for a physician to develop an effective care plan 
for the patient. 

     According to the National Osteoporosis Foundation ("NOF"), osteoporosis 
afflicts over 25 million Americans and over 200 million people worldwide. In 
the United States, approximately 1.5 million osteoporosis-related fractures 
occur each year, including more than 250,000 hip fractures, 500,000 vertebral 
fractures and 240,000 wrist fractures. For Caucasian women, it is estimated 
that the risk of hip fractures approximates the combined risks of breast, 
endometrial and ovarian cancers. In addition, approximately one in three 
women over age 65 will suffer vertebral fractures. By age 75, approximately 
one-third of all men will also be 


                                       4


<PAGE>


affected by osteoporosis. Industry studies estimate that the lifetime risk of 
hip fracture in men approximates the risk of prostate cancer. 

     The World Health Organization estimates that the cost of 
osteoporosis-related fractures in the United States exceeds $7 billion 
annually. The most severe osteoporosis-related fracture is that of the hip. 
Over 95% of osteoporosis-related hip fractures require hospitalization, 
between 12% and 20% result in fatality from other health complications 
arising from the fractures and half of the patients who survive are unable to 
walk unassisted for the rest of their lives. Another 25% are confined to 
long-term care under supervised conditions. 

     There are several groups of women at high-risk for osteoporosis. The 
largest of these groups is post-menopausal women. At menopause, the ovaries 
cease producing estrogen, a hormone with anti-resorptive properties, which 
results in an increase in the rate of bone loss. In addition, women have 10% 
to 25% less bone mass at maturity than men, leaving them more susceptible to 
osteoporosis. Another condition that increases the risk of 
osteoporosis-related fractures is amenorrhea, the cessation of menstruation 
not associated with the onset of menopause, which results from the 
interruption of estrogen production and consequently decreases bone mass. 
Amenorrhea generally affects women who participate in extremely rigorous 
exercise regimens or have eating disorders. 

     According to the NOF, certain other risk factors increase an 
individual's likelihood of developing osteoporosis. These include (i) genetic 
factors, such as Caucasian or Asian descent, thin frame and/or small bones, 
and a family history of fractures in elderly women, (ii) lifestyle factors, 
such as cigarette smoking, excessive use of alcohol or caffeine, chronically 
low calcium intake, and inactivity, and (iii) drug-induced factors resulting 
from use of medications for certain conditions, such as arthritis, asthma, 
endometriosis and thyroid disorders. 

OTHER BONE-RELATED DISEASES

     In addition to developing diagnostic tests to assess osteoporosis, 
assays for a number of other diseases that can adversely affect bone 
remodeling, including Paget's disease of bone, cancers that metastasize to 
bone, hyperthyroidism, hyperparathyroidism, osteoarthritis and growth hormone 
deficiency are also being developed. Unlike osteoporosis, these diseases have 
physical symptoms that may alert a physician to the possibility of bone loss 
and, accordingly, the need to monitor the bone remodeling process with 
diagnostic tests. 

          PAGET'S DISEASE.  Paget's disease is a chronic bone disease
          characterized by the enlargement and softening of bones. This
          condition is thought to be caused by a localized disruption of normal
          bone remodeling. Paget's disease is manifested by the presence of an
          increased number of abnormally enlarged osteoclasts resulting in an
          increase in bone resorption. In addition, the bone formation process
          is also increased, resulting in structurally inferior bone, which may
          increase a patient's risk of fracture. 

          CANCER.  Cancers that metastasize to bone adversely affect skeletal
          metabolism. Approximately 25% of cancer patients will have metastases
          of their primary tumor to bone. Several common malignancies, including
          prostate, breast and lung cancers, spread more often to bone than to
          other tissues. 

          DRUG-RELATED DISEASES.  Skeletal degradation can also be a
          drug-induced side-effect. Many drugs and medications approved to treat
          other diseases and disorders, including thyroid medications, steroids
          to treat asthma and arthritis, 


                                       5


<PAGE>


          and drugs to treat infertility and endometriosis, are known to 
          cause increased bone resorption. 

          HYPERTHYROIDISM/HYPERPARATHYROIDISM.  Hyperthyroidism is caused by
          either an excessive functional activity of the thyroid gland or by
          excessive doses of thyroid hormone. The resulting condition is
          characterized by an increased metabolic rate. One consequence of an
          increase in these hormones is an increase in bone remodeling.
          Hyperparathyroidism is a condition that results from an abnormal
          increase in the secretion of parathyroid hormone, which increases the
          breakdown of bone. 

          OSTEOARTHRITIS.  Osteoarthritis is characterized by degenerative
          changes in the bone and cartilage of one or more joints, which can
          lead to disability, pain and impairment of mobility. 

          GROWTH HORMONE DEFICIENCY.  Growth hormone deficiency particularly
          affects children and is characterized by a very low or absent
          production of growth hormone which retards normal growth rates of such
          children. 

THERAPIES FOR OSTEOPOROSIS

     During the past several decades, a number of therapies have been 
developed to address bone diseases and disorders. Most of these are 
prescribed therapies, including hormone replacement therapy ("HRT"), 
calcitonins and bisphosphonates, and are focused on preventing further bone 
loss rather than systemically forming new bone. Other products include 
supplements that are available over-the-counter, such as calcium and vitamin 
D. 

     The Company believes the market for drugs to treat osteoporosis will 
grow as a result of several factors, including worldwide aging of the 
population, heightened public awareness of osteoporosis, FDA approval of new 
therapeutics and the development and availability of effective diagnostic 
tests.

          HORMONE REPLACEMENT THERAPY.  Hormone replacement therapies, such as
          estrogen and progestin, are the most frequently prescribed drugs given
          to alleviate symptoms in post-menopausal women. HRT products act to
          decrease bone loss (are anti-resorptive) and are also approved for
          preventive treatment of osteoporosis. There are a number of estrogen
          products currently approved by the FDA and available worldwide for use
          in preventing or managing osteoporosis, including Wyeth-Ayerst
          Laboratories' Premarin, Ciba-Geigy Ltd.'s Estraderm, and Bristol-Myers
          Squibb Company's Estrace. In 1994, total sales of hormone replacement
          therapies, including oral, transdermal and other formulations, were in
          excess of $1.5 billion in the United States. 

          CALCITONINS.  Calcitonin acts to slow bone resorption and may be a
          viable substitute for estrogen as an anti-resorptive drug, especially
          in male patients or in those female patients who cannot tolerate, or
          choose not to use, hormone replacement therapy. Most formulations,
          however, are injectible and not as easily administered as oral
          medications. In the United States, Sandoz Ltd.'s Miacalcin and
          Rhone-Poulenc Rorer Inc.'s Calcimar are the only FDA-approved
          calcitonin products. 

          BISPHOSPHONATES.  Bisphosphonates have been researched for use in the
          prevention and treatment of osteoporosis. Fosamax, a bisphosphonate
          from 


                                       6


<PAGE>




          Merck & Co., Inc. was approved in late 1995 for the treatment of
          patients with low bone mineral density. Additionally, Didronel, a
          bisphosphonate from The Procter & Gamble Company, is currently
          approved for use in treating Paget's disease. Several other
          bisphosphonates are in various stages of development. 

          OTHERS.  Other products used for the prevention of bone loss include
          vitamin D and calcium supplements. In addition, injectible vitamin D
          metabolites are a prescribed therapy for preventing bone loss that are
          widely used in Japan but are not approved in the United States. There
          are a number of other new therapies under development, including
          estrogen analogs designed to minimize the side effects of HRT and slow
          release sodium fluoride, which is believed to increase bone mineral
          density. 

OSTEOPOROSIS-RELATED DIAGNOSTICS

     IMAGING METHODS

     Several imaging technologies provide varying degrees of sensitivity for 
the assessment of bone mass. For many years, changes in bone mass have been 
roughly assessed with traditional x-ray technology, which can reveal a 
decrease in bone mass only after approximately 30% of the bone has been lost. 
Newer techniques for measuring bone loss with improved accuracy and precision 
have been developed that can measure bone mass and bone mineral density 
("BMD"). 

     Dual energy x-ray absorptiometry ("DEXA") is the most advanced imaging 
system currently used to measure BMD. DEXA offers faster image-capture time 
(approximately 10 minutes) and higher resolution measurements with lower 
overall radiation doses than early imaging methods. DEXA systems are 
available for use in partial and whole body scans. 

     Recently, additional technologies, such as ultrasound, have been 
developed that may be less expensive than DEXA, do not involve radiation and 
may provide information concerning bone structure and quality. 

     DEXA and ultrasound systems are more precise and accurate than earlier 
imaging methods, but changes in bone mass occur so slowly relative to the 
sensitivity and precision limitations of these technologies that these 
technologies have limitations in assessing the rate of bone loss on a 
real-time basis. The inability of DEXA and ultrasound to measure the rate of 
bone loss in real time limits its use in determining treatment efficacy or 
patient compliance in adhering to treatment regimens. To be effective, these 
technologies require initial and follow-up measurements which can be compared 
in order to assess bone loss. Typically the period between measurements can 
be up to two years to effectively diagnose a differential. This period is one 
of the many reasons why biochemical markers which detect bone loss are 
important for effective health care management. However, DEXA and ultrasound 
measurements can provide a physician with important data regarding a 
patient's bone characteristics at a given point in time. This data can be 
helpful in determining which therapeutic regimes are most appropriate in 
light of the patient's current bone status.

     TESTS FOR BIOCHEMICAL MARKERS

     Biochemical markers are substances that are produced by the body that 
correlate directly or indirectly to disease or bodily function. Biochemical 
markers have been discovered that can be used to assess the dynamic rates of 
bone resorption and bone formation, unlike imaging methods, which determine 
bone mass at a specific point in time. The use of biochemical markers could 
therefore complement imaging methods in providing a more complete picture of 
bone metabolism. 

     Several biochemical markers of bone resorption have been discovered over 
the past few decades. Two such markers are the pyridinium crosslinks, 
pyridinoline ("Pyd") and deoxypyridinoline ("Dpd"). Pyd and Dpd are modified 
amino acids that crosslink adjacent collagen molecules thereby providing 
structural rigidity to bone. During the bone remodeling process, collagen is 
degraded by osteoclasts and Pyd and Dpd fragments are released into 
circulation and excreted into bodily fluids, such as blood and urine. The 
utility of pyridinium crosslinks as an indicator of the rate of bone 
resorption has been demonstrated with studies of bone biopsy, where the 
levels of the pyridinium crosslinks in urine directly correlated with the 
level of osteoclastic activity in bone biopsy samples. 

     In addition to biochemical markers for resorption, markers have been 
discovered for bone formation. These include certain molecules that are 
released into the blood as a result of osteoblastic activity, such as 
alkaline phosphatase and osteocalcin. 

     Several methods exist to measure biochemical markers. An established 
method to measure pyridinium crosslinks in urine has traditionally been high 
pressure liquid chromatography ("HPLC"). HPLC is a complex procedure that 
requires a trained technician and is typically performed in a research 
laboratory. Although the HPLC method for measuring pyridinium crosslinks is 
extremely accurate, it is primarily a research tool and is not commonly used 
for routine clinical testing because it has low throughput, is expensive, and 
is labor intensive. 

     Immunodiagnostic tests are antibody-based tests that measure biochemical 
markers used to diagnose, screen or monitor disease progression, patient 
compliance and drug efficacy. Immunodiagnostic tests have been developed that 
measure biochemical markers of bone resorption and biochemical markers of 
bone formation. Urinary Pyd and Dpd crosslinks consist of free crosslinks 
(approximately 40%), crosslinks linked to one or two amino acids 
(approximately 40%), crosslinks linked to smaller peptides (approximately 
15%) and crosslinks linked to larger peptides (approximately 5%). 
Immunodiagnostic tests can be used to measure any of these Pyd and Dpd 
crosslinks. In general, free crosslinks occur in consistent proportion to 
total crosslinks. This relationship suggests that an increase in the amount 
of free crosslinks corresponds to an increase in total crosslinks and hence 
corresponds to an increase in the rate of bone resorption. As a result, 
immunodiagnostic tests that measure these free crosslinks generally provide 
similar information, and have a high degree of correlation, to results of the 
HPLC procedure, but in an easier, less expensive more reliable and 
reproducible method suitable for routine use by clinical laboratories. 

     In September 1995, Dr. Pierre Delmas, of the INSERM Research Unit in 
Lyon, France and a member of Metra's Scientific Advisory Board, announced 
interim investigational data from an ongoing independent and blinded study 
conducted at the Claude Bernard University, also in Lyon, that supports the 
clinical utility of measurement of free Dpd. Data from the French "EPIDOS" 
prospective study of more than 7,500 women over 75 years of age found that 
the measurement of free Dpd was correlated with increased risk of hip 
fracture and, therefore, may have the potential to determine individuals at 
greater risk of this potentially 


                                       8

fatal trauma. Women whose hips had fractured possessed elevated Dpd when 
compared to women in the study of the same age who did not fracture. The 
investigational study suggests that patients with higher levels of Dpd may 
have a greater risk of hip fracture. 

     In an additional independent study conducted in Rotterdam, The 
Netherlands, higher Dpd levels appeared to be associated with a higher risk 
of hip fracture in independently living subjects. This epidemiological study 
followed 7,900 individuals, 55 years of age and older, for nearly two and 
one-half years. 

CARTILAGE BIOLOGY

     Cartilage is a compressable tissue which covers the ends of bones and 
allows them to glide smoothly and freely within a joint. Cartilage is 
composed primarily of one cell type, the chondrocyte, and an extensive 
extracellular matrix. The main structural elements of this matrix are large 
proteoglycan aggregates, responsible for the tissue's elastic properties, and 
a collagen fiber meshwork, responsible for the tissue's resilience. Joints 
are classified as either freely mobile, slightly mobile, or fixed. Freely 
mobile joints, or synovial joints, are enclosed by a joint capsule which is 
lined by a synovial membrane, or synovium. The synovium is lined by cells, or 
synoviocytes, which produce a small amount of liquid called synovial fluid 
that nourishes and lubricates the joint. Cartilage breakdown may be 
attributed to an autoimmune response in the synovial fluid, and/or a 
degrative enzymatic process within the cartilage itself, and when the 
cartilage breaks down, a disease known as arthritis may occur. 

ARTHRITIS

     Arthritis is generally characterized by joint pain and swelling. There 
are more than 100 types of arthritis affecting approximately 40 million 
people in the United States. The two most prevalent forms of arthritis are 
osteoarthritis ("OA") and rheumatoid arthritis ("RA"). Although the causes of 
OA and RA are very different, both diseases result in the common problem of 
joint destruction.

     Osteoarthritis is the most common form of arthritis. The prevalence of 
osteoarthritis among individuals aged 45 to 50 is estimated to be 
approximately 30%, and approaches a 60% prevalence rate for individuals over 
65 years of age. Osteo, or degenerative, arthritis is a disease that is 
believed to result from the breakdown of cartilage in a specific joint or 
joints and bone proximate to joints. Osteoarthritis can affect any type of 
joint, but the disease most commonly occurs in weight bearing joints such as 
the hips, knees and spine. 

     Rheumatoid arthritis is the second most common form of arthritis. In 
North America, it is estimated that two million people are afflicted with 
this condition and in excess of $200 million dollars is spent each year for 
the care and treatment of the disease. Rheumatoid arthritis can occur at any 
age, but the onset of the disease typically peaks between ages 35 and 45. 
This disease is thought to be a systemic autoimmune disorder in which the 
synovium becomes inflamed, causing hot, tender, and swollen joints. Only the 
freely mobile joints such as hands, feet and knees are affected by this form 
of arthritis. As the disease progresses, the cartilage and eventually the 
bone are destroyed by various autoimmune-mediated enzymatic responses. This 
process results in continuous pain, progressive deformity, and disability. 

ARTHRITIS THERAPIES

     No known treatments can stop or reverse osteoarthritis. Current 
treatment for OA is primarily focused on reducing pain, minimizing 
inflammation, and maximizing joint function. Physicians most commonly 
recommend analgesics such as aspirin or acetaminophen to reduce 


                                       9


<PAGE>


pain and non-steroidal anti-inflammatory drugs ("NSAIDs") such as ibuprofen 
to reduce inflammation. In advanced OA, more invasive measures such as 
injection of steroids into the joint space, arthroscopic surgery, and partial 
or total joint replacement can be used. 

     For treatment of RA, physicians commonly prescribe NSAIDs in an effort 
to reduce inflammation. Additionally, doctors often prescribe other 
non-specific drugs designed to reduce the body's immune response and 
associated inflammation. The effectiveness of these therapies is variable 
from patient to patient, and may involve various side effects and 
complications. 

     There are numerous pharmaceutical companies working to develop more 
effective therapies to treat OA and RA. During the early stages of arthritis, 
the patient is not necessarily aware of the progression of the disease until 
the associated pain and swelling occurs accompanied by reduced joint 
mobility. In certain patients who are experiencing pain, there may be little 
correlation between the severity of active disease and the amount of pain. A 
biochemical marker test integrated into the overall health care of a patient 
may identify the early stages of arthritis and enable more effective 
treatments with emerging therapies along with subsequent therapeutic drug 
monitoring. 

ARTHRITIS DIAGNOSTICS

     Many diagnostic tools for OA and RA exists, but none is specific to 
arthritis or can confirm a diagnosis of either type of disease or accurately 
assess disease progression. Current diagnosis of arthritis is based on: 

     -    Medical history and a physical examination; 

     -    Symptoms, i.e., swelling, red and hot joints, nodules under the skin,
          and stiffness; 

     -    X-rays, which are not designed for detection of soft tissue disorders,
          and which can detect a pattern of visible damage only after multiple
          exposures; and 

     -    In the case of RA, laboratory tests for anemia, low white-blood-cell
          count, rheumatoid factor ("RF") and erythrocyte sedimentation rate
          ("ESR"). Anemia can be an accompanying symptom of rheumatoid arthritis
          but is not caused by or otherwise necessarily correlated to arthritis.
          RF is present in 85% of people with rheumatoid arthritis, but also
          does not necessarily indicate rheumatoid arthritis. ESR indicates a
          systemic inflammatory condition but not necessarily rheumatoid
          arthritis. 

MARKET FOR IMMUNODIAGNOSTIC TESTS

     Diagnostic tests are widely used for both research and routine clinical 
use. Academic and clinical researchers in universities, teaching hospitals, 
pharmaceutical companies and government research units, such as the National 
Institutes of Health, use research products routinely. However, not all 
research products are introduced for routine clinical use for many reasons, 
including a lack of clinical utility or cost of obtaining regulatory 
approval. 

     Immunodiagnostic tests are performed in a variety of technical formats. 
A common format for research and clinical testing is the microtiter plate 
system utilizing enzyme immunoassay ("EIA") detection. EIA utilizes an immune 
reaction, that is, an antibody reacting with an antigen, and the detection of 
the reaction using enzymes which are attached to the reactants as indicators. 
EIA's are based on two phenomena: (i) the discriminatory nature of 


                                       10


<PAGE>


antibodies (proteins that bind specifically to antigens), which have an 
affinity for specific compounds (i.e. antigens), and (ii) the high catalytic 
power and specificity of enzymes. Although this technology is considered an 
established industry standard, this manual format is relatively slow, has low 
throughput, and requires skilled technicians. Instrument systems have been 
developed that automate tests to increase throughput and decrease cost per 
test. Most of the widely used immunodiagnostic tests have been adapted for, 
and are used on, automated systems. These formats are used in hospitals and 
clinical laboratories throughout the world. In general, faster and more 
convenient formats are required and in development for point-of-care use in 
physicians' offices or for home use. 

BUSINESS STRATEGY

     The Company is a leader in developing and commercializing innovative 
products for the detection and management of metabolic bone diseases and 
disorders. The Company's general business stategy is comprised of certain key 
elements: first, the continual development of new diagnostic products to 
complement the Company's existing products for the detection and management 
of metabolic bone and connective tissue disorders; second, the establishment 
of collaborative relationships with corporate partners for co-promotion 
(medical education and awareness), and co-development of the Company's tests 
with several diagnostic industry leaders to establish a dominant position in 
the strategically important clinical laboratory market, where the majority of 
the testing in the United States is accomplished today by providing tests in 
either an automated or manual format; and third, the development of 
distribution capabilities to maximize market share through partnerships with 
diagnostic companies and the expansion of the Company's direct sales 
capabilities. The Company's business strategy includes the following 
components: 

     -    DEVELOP PROPRIETARY DIAGNOSTICS AND DISCOVER ADDITIONAL MARKERS.  The
          Company's focus is on the discovery of biochemical markers and the
          development of proprietary diagnostic tools for major bone, cartilage
          and other connective tissue diseases. The Company is seeking to
          develop products that have a high degree of specificity to the disease
          being measured, and that will achieve wide research acceptance and
          clinical utility. 

     -    OFFER A PORTFOLIO OF DIAGNOSTIC PRODUCTS.  The Company believes that
          no single technology will give physicians a complete picture of the
          metabolic bone remodeling process. The Company's product strategy is
          focused on developing a portfolio of tests and complementary
          diagnostic devices to provide comprehensive clinical information to
          physicians for targeted diseases. The Company has developed and will
          continue to develop multiple tests for bone resorption and formation,
          as well as tests for other connective tissues, and is developing an
          ultrasound-based diagnostic device in order to provide the physician
          with information relevant to a patient's overall bone characteristics.
          

     -    EXPAND CLINICAL UTILITY FOR APPROVED PRODUCTS.  The Company has
          entered into a number of international academic collaborations and
          pharmaceutical company collaborations, as well as Metra sponsored
          clinical studies, designed to gather data to submit to the FDA for
          clearance to market the Company's existing products for broader
          clinical claims. This work is primarily targeted at application of the
          Company's technologies in therapeutic drug monitoring, fracture risk
          assessment, monitoring of metastatic cancers and periodontal disease. 


                                       11


<PAGE>


     -    PROVIDE MULTIPLE TEST FORMATS.  In order to address the highly
          fragmented market for its diagnostic tests, the Company has
          established collaborations to format its products for use with
          existing laboratory equipment and instrumentation. The Company will
          seek to adapt its products to work with the installed base of
          automated and other instrument systems supplied by a number of
          companies. In the future, Metra expects to offer its products in
          point-of-care or other rapid-test formats. 
     
     -    INCREASE MARKET EDUCATION AND ADOPTION.  The Company develops its
          products initially as research products and works with the medical and
          scientific communities to establish and assess initial clinical
          utility and to obtain feedback prior to pursuing clinical
          introduction. The Company, together with its collaborative partners,
          is conducting studies to determine the clinical utility of its
          research use-only biochemical marker tests. In addition, the Company
          will continue to pursue collaborative arrangements with pharmaceutical
          partners that have or are developing therapies for osteoporosis to
          enhance market awareness of the Company's products. 
     
     -    EXPAND SALES IN INTERNATIONAL MARKETS.  The Company sells its products
          internationally for both research and clinical use. The Company plans
          to expand its international sales and marketing efforts to third-party
          payors to establish reimbursement for its products. The Company
          believes that the use of its products by researchers and physicians
          will accelerate the determination of clinical utility and market
          acceptance of its products. 

     The key elements of the Company's strategy are based on a belief that a 
small percentage of the population at risk for certain bone and connective 
tissue diseases and disorders, such as osteoporosis, RA and OA, are not 
diagnosed early enough for preventative treatment to be effective. The 
Company believes that the historical lack of consistent therapeutic 
intervention can be traced in part to the limited availability of timely, 
cost-effective and accurate methods to detect and monitor these diseases. The 
Company believes that the demand for its products will be driven in part by 
physicians' need to easily, inexpensively and accurately (i) identify those 
persons most at risk before significant onset of these diseases, (ii) 
quantify the parameters of each patient's disease progression, (iii) 
determine therapeutic dosage and duration of therapy and (iv) monitor the 
effectiveness of, and compliance with, prescribed therapies. 

PRODUCTS

     The Company has developed and is currently marketing for research and 
clinical use four immunodiagnostic tests to measure bone resorption and 
formation and one immunodiagnostic test to detect certain pediatric growth 
disorders. In draft guidelines to pharmaceutical companies developing new 
osteoporosis drugs, the FDA recommends using a combination of three 
biochemical markers that together detect both resorption and bone formation 
to assess efficacy as part of their pre-clinical and clinical testing. These 
are (i) urinary pyridinium crosslinks, (ii) osteocalcin and (iii) 
bone-specific alkaline phosphatase. The Company currently offers tests for 
each of these biochemical markers. 

     The Company's Pyrilinks tests and Alkphase-B test are proprietary and 
measure specific biochemical markers. Although the Company's other tests such 
as NovoCalcin and Prolagen-C measure markers that are not proprietary and are 
available from other companies, these tests allow the Company to offer a more 
complete line of relevant clinical and research use tests to measure bone 
metabolism. The following table identifies the Company's products,

</TABLE>

BONE RESORPTION TESTS

     The Company's primary tests measure free pyridinium crosslinks, which 
are well characterized markers of bone resorption. Metra's Pyrilinks and 
Pyrilinks-D immunoassays are inexpensive, specific tests capable of directly 
measuring free pyridinium crosslinks (Pyd and Dpd) through simple urine 
tests. The results of Metra's bone resorption tests have a high correlation 
co-efficient (greater than 90%) to those derived from HPLC, which is 
generally accepted as an extremely accurate method for measuring pyridinium 
crosslinks. The Company estimates that the cost to the patient of its tests 
is approximately $30 to $80, depending on the mark-up charged by 
distributors, clinical laboratories and physicians. 

     Pyrilinks Polyclonal, Metra's first immunoassay, was introduced in 
Europe in 1992 for sale as a research use only product and is a polyclonal 
antibody test that measures free pyridinium crosslinks. The second generation 
of the test, Pyrilinks, was introduced in Europe in 1994 and uses a 
monoclonal antibody to measure free pyridinium crosslinks. The modifications 
in Pyrilinks reduced manufacturing costs and shortened time for results to a 
few hours, as compared to overnight for Pyrilinks Polyclonal. The biochemical 
markers measured by Pyrilinks and Pyrilinks Polyclonal result from the 
breakdown of collagen found in both bone and cartilage. In November 1995, 
Metra received 510(k) clearance to market both Pyrilinks Polyclonal and 
Pyrilinks as quantitative measures of the excretion of pyridinium crosslinks 
as an indicator of type I collagen resorption, especially bone collagen. Due 
to the improvements of Pyrilinks over Pyrilinks Polyclonal, the Company is 
not actively promoting or marketing


                                       13


<PAGE>


Pyrilinks Polyclonal and may in the future discontinue manufacture and sale 
of this product. Pyrilinks-D utilizes a more bone-specific biochemical marker 
to measure bone resorption, was introduced for research use only in 1993 and 
received FDA 510(k) clearance for clinical use in December 1995 as an 
indicator of bone resorption. 

BONE FORMATION TESTS

     In addition to tests that measure bone resorption, Metra has developed 
immunodiagnostic tests that measure bone formation. The Company believes that 
multiple formation assays are important because increases or decreases in 
bone formation provide relevant research, diagnostic and therapeutic 
information. 

     Alkphase-B, Metra's newest bone formation immunodiagnostic test, 
measures bone-specific alkaline phosphatase. Alkaline phosphatase is found 
not only in bone but also in the liver, kidney and other organs. Metra 
believes that Alkphase-B is a significant improvement over other widely 
available alkaline phosphatase tests because it measures only the alkaline 
phosphatase generated from bone formation. In August 1995, Metra received 
510(k) clearance to market Alkphase-B as an aid in the management of patients 
diagnosed with Paget's disease. 

     NovoCalcin, an immunoassay introduced in July 1993, is a test to measure 
intact osteocalcin. Osteocalcin is a small peptide that is produced only by 
osteoblasts during the formation phase of the bone remodeling process. Up to 
20% of osteocalcin is released into circulation during bone formation, and 
the rest is deposited into the bone matrix and later released by osteoclasts 
during the process of bone resorption. NovoCalcin can be used to measure bone 
remodeling or as a specific marker of bone formation. NovoCalcin is marketed 
as a research and clinical test in certain European countries and as a 
research test in Japan and the United States. In the United States, the 
Company believes that PMA approval will be required for clinical use, and the 
Company has not determined whether it will pursue FDA approval for this 
product. 

     GROWTH DISORDER TEST

     In response to the development of new pediatric growth therapies such as 
human growth hormone, Metra has developed an immunodiagnostic test that is 
used as an indicator of bone growth, called Prolagen-C, which was launched in 
November 1993 for research use only. This immunodiagnostic test measures 
collagen type I carboxyterminal propeptide ("CICP"), a marker for collagen 
production in serum. Unlike osteocalcin, 100% of newly synthesized CICP is 
released into circulation in proportion to the amount of new bone formed. The 
Company believes Prolagen-C may be useful for monitoring the effectiveness of 
certain pediatric growth disorder therapies. Prolagen-C is marketed as a 
research and clinical test in certain European countries and as a research 
test in Japan and the United States. In the United States, the Company 
believes a PMA approval will be required for clinical use and the Company has 
not determined whether it will pursue FDA approval for the product. 

     There can be no assurance that the Company will have adequate resources 
or the clinical data necessary to file required state, federal and 
international regulatory filings required to further develop and 
commercialize these resorption, formation and growth disorder products. Even 
if the Company has the necessary resources and decides to seek regulatory 
approvals for research and/or clinical sale of these products, there can be 
no assurance that the Company will obtain approvals in a timely manner, if at 
all, that reimbursement in adequate amounts will be available, if at all, or 
that the products, even if approved, will be accepted as effective diagnostic 
tools by the medical community.

RESEARCH AND DEVELOPMENT

     The Company's research and development efforts are currently focused in 
four principal areas: (i) discovery and development of biochemical marker 
tests focused in the area of bone and cartilage diseases, (ii) conducting 
clinical studies designed to broaden the clinical claims for its existing 
products; (iii) formatting of Metra's existing tests in alternative formats 
to address different segments of the diagnostic market; and (iv) development 
of its recently acquired ultrasound technology. 

     NEW BONE AND CARTILAGE TESTS

     The Company has entered into a license agreement with NovaDx Inc. to 
develop and manufacture a microtiter plate assay for the measurement of 
YKL-40 ("Chondrex"), a novel glycoprotein which has been shown to be 
significantly elevated in OA and RA patients. The Company believes that 
YKL-40 may provide the basis for the development of a diagnostic test which 
can be utilized in the detection and management of OA and RA. In addition, 
the Company has entered into a collaborative agreement pursuant to which the 
Company will fund research and development of a new protein found in serum of 
patients with decreased bone density. 

     The Company is funding internal and third-party research and development 
efforts designed to identify and develop additional markers for bone and 
other connective tissue conditions and new immunoassays to measure markers 
that it believes will have clinical utility. As new immunodiagnostic tests 
are developed, the Company intends to offer them first to researchers, and, 
to the extent research in the medical community validates the clinical 
utility of measuring the relevant markers, to further develop and 
commercialize products based on existing immunodiagnostic technology formats. 
The Company currently sponsors research by physicians at research 
institutions including The Rowett Research Institute in Scotland, the 
University of Heidelberg in Germany, the University of California at San 
Francisco and at Cambridge University and St. Thomas Hospital in England. 

     CLINICAL STUDIES

     The Company is conducting clinical studies designed to gather data to 
submit to the FDA for clearance to market the Company's existing products for 
broader clinical claims. The Company is investigating use of its products in 
applications including therapeutic drug monitoring, fracture risk assessment, 
and monitoring of metastatic cancers and periodontal disease. 

     ALTERNATIVE TEST FORMATS

     The Company is reformatting certain of its tests to be run on Abbott 
Laboratories' installed base of automated diagnostic instruments. The Company 
has also entered into a collaborative agreement to develop and manufacture 
its Pyrilinks-D test in a radioimmunoassay format which was launched for 
clinical use in France in May, 1996. The Company believes that less 
complicated and capital intensive formats may be more suitable for 
decentralized testing in physician office laboratories, small clinics, 
satellite laboratories and for home use. Metra is also reformatting its lead 
bone resorption product, Pyrilinks-D, for the Cholestech point-of-care 
analyzer, named the L-D-X for use in the physicians offices.

     ULTRASOUND TECHNOLOGY

     In order to offer a broader portfolio of products that will provide 
physicians with more comprehensive clinical information regarding the 
metabolism and clinical status of bone, Metra recently acquired Osteo 
Sciences Corporation, a company developing ultrasound technology based on 
proprietary algorithms and designs. The Company is developing a portable 
ultrasound device designed to evaluate certain characteristics of bone that 
are associated with bone weakness and bone quality. The target market for the 
device will be physicians' offices or small group practices, which should 
provide physicians and patients with a convenient and cost effective 
alternative to the currently available techniques for assessing bone 
fragility.

     OTHER PROGRAMS

     In light of the Company's current focus on developing its ultrasound 
technology, its decision to further expand its panel of bone 
immunodiagnostics, and its entry into the cartilage field, the Company has 
deferred its development efforts relating to Factor BP-3, a blood test for 
insulin-like growth factor binding protein-3, and osteopoeitin ("OPO"), an 
osteogenic factor discovered by the Company. 

     As of June 30, 1996, the Company had 25 employees engaged in research 
and development. Research and development expenses for the fiscal years ended 
June 30, 1996, 1995, and 1994 were $4.3 million, $3.7 million, and $2.9 
million, respectively. 

     There can be no assurance that Metra will be successful in developing 
new products or that new products developed by the Company will receive 
necessary government approval or, if approved, will gain market acceptance. 
Any failure by the Company to successfully develop and introduce new products 
could have a material adverse effect on the Company's business, financial 
condition and results of operations. 

SALES AND MARKETING

     The Company's products are currently being marketed internationally for 
both clinical and research use.  In the United States, three of the Company's 
tests have received 510(k) clearance from the FDA for clinical use and two of 
the Company's tests are being marketed for research use only.  The company is 
currently marketing its products in Japan for research use only and for 
clinical as well as research use in numerous other European countries, 
including (but not limited to) Germany, Italy, Spain, and the United Kingdom. 
 The Company's approach is to initially market the tests for research 
purposes by academic and clinical researchers in universities, teaching 
hospitals, pharmaceutical companies and government institutions.  As 
regulatory clearances are obtained for clinical use, clinical reference and 
hospital laboratories are then targeted as customers.

     The Company's strategy is to sell and market its products through a 
direct sales force and through distribution alliances with diagnostic product 
companies. The Company has limited experience in sales, marketing and 
distribution of its products. The Company currently sells its products 
directly in the United States and the United Kingdom and through commissioned 
representatives in Italy. The Company intends to expand its marketing staff 
and direct sales force, and there can be no assurance that the Company will 
be able to do so cost-effectively, or that the Company's direct sales and 
marketing efforts will be successful. The market for the Company's products 
is fragmented and consists of clinical laboratories, reference laboratories, 
academic and clinical researchers in universities and physicians, among 
others. The Company plans to rely on its collaborative partners to help build 
market awareness and acceptance of the Company's products. There can be no 
assurance that the Company will be able to enter into


                                       16


<PAGE>


new alliances or that its distributors or collaborative partners will be 
successful in marketing, selling or gaining market acceptance for the 
Company's products. Outside the United States, the United Kingdom and Italy, 
the Company sells its products through distributors. 

     The Company's distribution alliances consist of arrangements with over 
30 distributors of diagnostic products that have well established 
distribution channels in the Company's markets, including Hoechst Behring 
(France), DPC Biermann (Germany), Dade Diagnostics (Australia) and Amersham 
K.K. (Japan). Product revenues from one customer constituted 12% of total 
revenues for the year ended June 30, 1996.  Product revenues from two 
distributors constituted 12% and 11%, respectively, of total revenues for the 
year ended June 30, 1995. The loss of one or more of these distributors or 
the inability to find new distributors could have a material effect on the 
Company's business, financial condition and results of operations. 

     International product sales accounted for approximately 78%, 78% and 72% 
of product revenues for the fiscal years ended June 30, 1996, 1995, and 1994, 
respectively. The Company expects that such sales will continue to account 
for a significant portion of the Company's revenues in the future. In order 
to successfully expand international sales, the Company may need to establish 
additional foreign operations, hire additional personnel and recruit 
additional international distributors and commissioned representatives. This 
will require significant management attention and financial resources and 
could adversely affect the Company's operating margins. In addition, to the 
extent that the Company is unable to effect these additions in a timely 
manner, the Company's growth, if any, in international sales will be limited, 
and the Company's business, financial condition and results of operations 
could be materially adversely affected. In addition, there can be no 
assurance that the Company will be able to maintain or increase international 
sales of the Company's products. The Company's international revenues are 
currently denominated in United States dollars. As a result, increases in the 
value of the United States dollar relative to foreign currencies could make 
the Company's products more expensive and, therefore, potentially less 
competitive in those markets. Additional risks inherent in the Company's 
international business activities generally include unexpected changes in 
regulatory requirements, tariffs and other trade barriers, longer accounts 
receivable payment cycles, difficulties in managing international operations, 
potentially adverse tax consequences including restrictions on the 
repatriation of earnings, and the burdens of complying with a wide variety of 
foreign laws. There can be no assurance that such factors will not have a 
material adverse effect on the Company's future international sales and 
consequently, the Company's business, financial condition and results of 
operations. 

     The Company is working with a number of diagnostic companies, including 
Abbott Laboratories, Bayer Corporation, Ciba Corning Diagnostics, and 
Diagnostics Products Corporation to format Metra's products for incorporation 
into these companies' existing installed base of high-speed, automated 
testing systems. The Company believes these collaborative programs will 
facilitate the development of cost-effective, disease-specific testing 
programs for the managed-care market. The Company intends to market directly 
to third-party payors. 

     The Company believes that educating patients and physicians about the 
long-term health benefits and cost-effectiveness of diagnosis and treatment 
of bone diseases and disorders at an early stage is critical to market 
acceptance for the Company's products. The Company believes that the trend 
toward management of health care costs in the United States will lead to 
increased awareness of and emphasis on disease prevention, and as a result, 
will increase demand for cost-effective diagnostic tests. 


                                       17


<PAGE>


     The Company will need to rely on current and any future collaborative 
partners to help build market awareness and acceptance of the Company's 
products. The Company has entered into marketing collaborations with several 
pharmaceutical companies, including Wyeth-Ayerst Laboratories, to promote 
patient and physician education, to help identify patients at risk and to 
monitor drug compliance. The Company, together with its partners, will 
continue to originate research and clinical studies to demonstrate and 
explain how the Company's products relate to improvements in early detection, 
disease management and drug compliance. There can be no assurance that the 
Company will be able to enter into new alliances or that its distributors or 
collaborative partners will be successful in marketing, selling or gaining 
market acceptance for the Company's products. The Company is initiating 
programs with physicians and consumer advocacy groups to provide a better 
understanding of metabolic bone diseases such as osteoporosis. The commercial 
success of the Company's products will depend upon their acceptance by the 
medical community and third-party payors as clinically useful, cost-effective 
and safe. The use of pyridinium crosslinks to measure bone loss and the use 
of markers such as bone-specific alkaline phosphatase to measure bone 
formation are relatively new technologies. Market acceptance will depend on 
several factors, including the establishment of clinical utility of these 
biochemical markers, the receipt of regulatory clearances where required, the 
development of diagnostic tests that can be processed using commercially 
available automated systems, the availability of third-party reimbursement, 
extensive physician education and the approval and commercial acceptance of 
therapies for the treatment of osteoporosis. In addition, research is in 
progress to determine whether certain therapies for osteoporosis and other 
bone diseases diminish the reliability of certain markers measured by the 
Company's tests. An adverse outcome in this research could limit the market 
acceptance of the Company's products because it could indicate that they have 
reduced utility in the management of certain drug therapy regimens. Further, 
clinical research is in progress to determine the clinical utility of 
biochemical markers, including the Company's products. Adverse results from 
such research have in the past and may in the future be made public. Such 
adverse results could limit the market acceptance of the Company's products. 
There can be no assurance that the Company's products will gain market 
acceptance. Failure to achieve market acceptance would have a material 
adverse effect on the Company's business, financial condition and results of 
operations. 

COLLABORATIVE RELATIONSHIPS

     The Company has entered into collaborative relationships which provide 
technological, clinical, marketing, financial and other key resources. 
Important elements of the Company's strategy are (i) to collaborate with 
corporate partners to develop additional markers and multiple formats for its 
tests, including automated systems, and eventually rapid tests for 
point-of-care use in physicians' offices or for home use, and (ii) to develop 
additional corporate alliances with pharmaceutical partners in order to 
facilitate the Company's market education and adoption strategy. The revenues 
from license fees and milestone payments from certain of these relationships 
have historically accounted for a significant percentage of the Company's 
revenues. The Company has entered into contractual relationships with the 
following entities: 

DEVELOPMENT OF ADDITIONAL MARKERS

     NOVADX INC.  In January 1996, Metra and NovaDx Inc. entered into a
     development and license agreement pursuant to which Metra received
     worldwide exclusive rights to manufacture and market Chondrex in manual
     formats and worldwide co-exclusive rights, with rights to sublicense, to
     manufacture and market Chondrex in automated formats. Chondrex is a blood
     test which the Company believes may provide the basis for the development
     of a diagnostic test which can be utilized in the detection and management
     of OA and RA. This technology has been licensed to NovaDx by the


                                       18


<PAGE>


     University of California Regents, is being developed by NovaDx and, 
     if successfully developed, Metra will manufacture, market and distribute 
     the test. This agreement also allows Metra to license additional 
     biochemical markers of joint disease developed by NovaDx. 

     CAMBRIDGE UNIVERSITY AND ST. THOMAS HOSPITAL.  In January 1996, Metra,
     Cambridge University and St. Thomas Hospital in England entered into a
     development agreement pursuant to which Cambridge University and St. Thomas
     Hospital agreed to develop a bone-specific biochemical marker based on
     their discovery of a new protein in serum of patients with decreased bone
     density. If successfully developed, Metra plans to develop and
     commercialize this proprietary osteoporosis-specific test in a manual assay
     format and thereafter may adapt this test for automated immunodiagnostic
     instruments and physician office formats. 

MULTIPLE FORMATS

     CIBA CORNING DIAGNOSTICS CORPORATION ("CCD").  In November 1993, Metra and
     CCD (a wholly owned subsidiary of Chicon Corporation) entered into a
     license and supply agreement. Pursuant to the license agreement, CCD will
     develop tests for bone resorption for its automated ACS:180 system using
     Metra's pyridinium crosslinks technology. CCD plans to commercialize the
     test during 1996 in this format, except in Japan. Metra has received
     license fees and milestone payments and sells reagents to CCD for use in
     its development program. Metra will receive royalty payments on any sales
     of CCD's systems, and CCD will purchase reagents from Metra for
     incorporation into CCD's systems. In June 1990, Metra and Ciba-Geigy
     entered into a development and license agreement to commercialize Metra's
     pyridinium crosslinks technology. In connection with entering into this
     agreement, Ciba-Geigy made an equity investment in the Company and paid
     Metra license fees and milestone payments.  In September 1996 the Company
     announced the filing of a 510(k) premarket notification with the FDA for
     clearnace to market the Company's Pyrilinks-D bone resporption technology
     for clinical use on CCD's ACS 180 automated immunoassay system.

     DIAGNOSTIC PRODUCTS CORPORATION ("DPC").  In December 1993, Metra and DPC
     entered into a development and manufacturing agreement pursuant to which
     DPC will incorporate the Company's pyridinium crosslinks technology into
     DPC's Immulite automated system used by hospitals and research and clinical
     laboratories. Metra has rights to market any test developed and will pay
     royalties on the future sales of such tests. 

     IMMUNODIAGNOSTIC SYSTEMS, INC. ("IDS").   In January 1995, Metra entered
     into a collaborative agreement with IDS to develop and manufacture a
     Pyrilinks-D assay in a radioimmunoassay ("RIA") format. IDS will
     manufacture the RIA test for Metra and will also have rights to sell the
     RIA test under its own name. . In May, 1996, the RIA test was made
     available for commercial use.  Metra will receive royalty payments on any
     sales of IDS' RIA products

     BIOQUANT, INC ("BIOQUANT").  In February 1995, Metra and BioQuant entered
     into a license and supply agreement pursuant to which BioQuant will
     evaluate the utility of Metra's pyridinium crosslinks excreted through
     perspiration with the aim of developing an alternative body fluid testing
     format. If successful, BioQuant will pay Metra royalties on sales of its
     products and will purchase Metra's reagents for incorporation into
     BioQuant's test. Metra has received license fees and sells reagents to
     BioQuant for use in its development program.  


                                       19


<PAGE>


     BAYER CORPORATION ("BAYER").  In July 1995, Metra and Bayer Corporation
     entered into a collaborative agreement to commercialize Metra's then
     available biochemical bone markers internationally, except in Japan. The
     agreement allows Bayer to market automated central laboratory systems,
     point-of-care assays, and over-the-counter tests based on Metra's
     proprietary technologies. In return Metra will receive milestone and
     royalty payments and will supply Bayer with reagents for each of the assays
     to be developed by Bayer. 

     ABBOTT LABORATORIES ("ABBOTT").  In February 1996, Metra and Abbott entered
     into a license, development and supply agreement for the commercialization
     of Metra's biochemical bone markers worldwide, except in Japan. The
     agreement grants Abbott the right to develop and market automated tests for
     metabolic bone and joint diseases based upon Metra's proprietary
     technologies. Under the agreement, Abbott will provide funding and
     instruments to Metra for co-development of Metra's existing and future
     technologies on Abbott's automated systems. Additionally, Metra will
     receive a revenue stream from royalties and reagent sales to Abbott.

     CHOLESTECH.  In May 1996, the Company entered into a license, development,
     supply and marketing agreement for the commercialization of Metra's
     biochemical bone markers worldwide on Cholestech's proprietary point-of-
     care analyzer, the L-D-X.  Under the terms of the agreement, Cholestech
     will be responsible for developing an immunoassay cassette incorporating
     the Pyrilinks-D assay and obtaining all regulatory clearances prior to
     marketing.  Cholestech will market the test through its existing US
     distributor network and will work together with Metra to market the system
     internationally.  Upon entering the agreement, Metra made a small equity
     investment in Cholestech, with additional equity investments to be made by
     Metra based upon the achievement of certain product development milestones.

  MARKET EDUCATION AND ADOPTION

     SUMITOMO PHARMACEUTICALS LTD.  In March 1993, Metra and Sumitomo entered
     into a co-development agreement to develop new biomedical products for the
     detection and management of bone and other connective tissue diseases for
     the Japanese market. In February 1995, Metra announced a research and
     development collaboration with Sumitomo for the Company's bone-specific
     alkaline phosphatase test. Sumitomo is responsible for all Japanese
     regulatory filings for both of these agreements and Metra is responsible
     for the research and development of these products. Metra receives license
     fees, milestone payments and royalties and will supply products to Sumitomo
     for distribution in Japan.

     WYETH-AYERST LABORATORIES ("WYETH-AYERST").  In November 1995, Metra and
     Wyeth-Ayerst entered into a marketing collaboration, pursuant to which
     Metra and Wyeth-Ayerst will promote education of the scientific and health
     aspects of bone disorders with the purpose of increasing awareness and
     treatment.

     AMERSHAM INTERNATIONAL PLC ("AMERSHAM").  In September 1996, the Company
     and Amersham entered into a distribution agreement through which Amersham
     received co-exclusive rights to market Metra's bone metabolism assays to
     the research community in the United States, United Kingdom, Eire, Denmark
     and Italy.  Since 1993, Amersham K.K. (a subsidiary of Amersham) has
     distributed the Company's assays for research use in Japan.



                                       20


<PAGE>


     The Company depends on most of these partners to develop and sell the 
Company's tests in the partners' formats or based on their proprietary 
systems. In particular, the Company will need to rely on collaborative 
partners to adapt the Company's products to high-volume automated instruments 
such as those sold by Abbott, Bayer, CCD and DPC. Substantially all of the 
Company's collaborative agreements are non-exclusive, and therefore such 
partners are free to enter into similar agreements with third parties, 
including the Company's competitors. In addition, the Company has not 
developed physician office or home-use adaptations of its products, and there 
can be no assurance that the Company or its collaborative partners will 
either develop such formats and sell the Company's tests on their formats, or 
obtain any required regulatory approvals. In addition, the Company has 
entered into a marketing collaboration with Wyeth-Ayerst Laboratories. The 
amount and timing of resources that Wyeth-Ayerst Laboratories or any other 
partner devotes to these activities is not within the control of the Company. 
In addition, several of these agreements may be terminated by the partner 
without cause. There can be no assurance that any of these partners will 
perform its contractual obligations or that it will not terminate its 
agreement. The failure to adapt the Company's products to different formats 
and instruments or otherwise to commercialize or co-promote such products, 
could have a material adverse effect on the Company's business, financial 
condition and results of operations. 

     The Company expects to enter into additional collaborative agreements in 
the future to develop, commercialize and sell current and future products. 
There can be no assurance that the Company will be able to negotiate 
acceptable agreements in the future, or that such new agreements or existing 
agreements will be successful. In addition, there can be no assurance that 
the Company's collaborative partners will not pursue alternative competing 
technologies. 

MANUFACTURING

     The Company's manufacturing operations are fully integrated and consist 
of antibody production, reagent purification, reagent and microtiter plate 
processing, filling, labeling, packaging and distribution. The Company has 
limited experience in manufacturing its products. To date, the Company's 
manufacturing activities have consisted primarily of manufacturing limited 
quantities of its immunoassays. If the Company experiences significant demand 
for its products, the Company will have to manufacture its products in 
commercial quantities in compliance with regulatory requirements at 
acceptable costs, and expend significant capital resources to develop 
large-scale manufacturing capabilities. If the Company is unable to develop 
large-scale manufacturing capabilities, the Company's competitive position 
and financial condition would be adversely affected. Failure to increase 
production volumes, if required, in a cost-effective manner or lower than 
anticipated yields or production constraints encountered as a result of 
changes in the manufacturing process could result in shipment delays as well 
as increased manufacturing costs, which could have a material adverse effect 
on the Company's business, financial condition and results of operations. 

     The majority of raw materials and purchased components used to 
manufacture the Company's products are readily available. However, certain of 
these materials are obtained from a sole supplier or a limited group of 
suppliers. In particular, the anti-osteocalcin antibody used in the Company's 
NovoCalcin test is currently available only from Haematologic Technologies, 
Inc. and the transducers incorporated in the Company's ultrasound product 
under development may only be available from a single manufacturer. In the 
event that the supply of anti-osteocalcin antibodies or, if the development 
of the ultrasound product is completed, the supply of the transducers, is 
interrupted for any reason, products from alternative suppliers are unlikely 
to be immediately available in sufficient volume to meet the Company's 
production needs, if at all. The Company does not maintain long-term 
agreements with any of its suppliers. The reliance on sole or limited 
suppliers and the failure to maintain long-term 


                                       21


<PAGE>


agreements with suppliers involves several risks, including the inability to 
obtain an adequate supply of required raw materials and components and 
reduced control over pricing, quality and timely delivery. Although the 
Company attempts to minimize its supply risks by maintaining an inventory of 
raw materials and continuously evaluating other sources, any interruption in 
supply could have a material adverse effect on the Company's business, 
financial condition and results of operations. 

     The Company's business, financial condition and results of operations 
would be adversely affected by the inability to obtain working capital, 
satisfactory manufacturing facilities, equipment and qualified manufacturing 
personnel. In addition, the Company's manufacturing facilities and its 
operations are subject to periodic inspections conducted by the FDA and 
equivalent inspections conducted by State of California officials, and its 
operations undergo current good manufacturing practices compliance 
inspections conducted by the FDA and equivalent inspections conducted by 
state officials. Because the Company has received FDA clearance to market 
certain of its products for clinical use, the Company expects that its 
facilities will be inspected by the FDA and by state authorities. Failure to 
comply with applicable regulatory requirements can result in, among other 
things, fines, suspension or withdrawal of clearances or of approvals, 
seizures or recalls of products, operation restrictions and criminal 
prosecutions. Furthermore, changes in existing regulations or adoption of new 
regulations could prevent the Company from obtaining, or affect the timing 
of, future clearances or approvals. There can be no assurance that the 
Company will be able to obtain necessary regulatory clearances or approvals 
on a timely basis or at all. Delays in receipt of or failure to receive such 
clearances or approvals or loss of previously received clearances or 
approvals could have a material adverse effect on the Company's business, 
financial condition and results of operations. 

In September 1996, the Company received ISO 9001 certification for its 
quality management systems.  The Company's certification is officially 
recognized by European and North American authorities and is accepted 
worldwide.

     The Company faces an inherent risk of exposure to product liability 
claims in the event that the use of its products is alleged to have resulted 
in adverse effects to a patient. The Company maintains a general insurance 
policy which includes coverage for product liability claims. The policy is 
limited to a maximum of $1.0 million per product liability claim and an 
annual aggregate policy limit of $1.0 million. There can be no assurance that 
liability claims will not exceed the coverage limits of such policy or that 
such insurance will continue to be available on commercially reasonable terms 
or at all. Consequently, a product liability claim or other claim with 
respect to uninsured liabilities or in excess of insured liabilities could 
have a material adverse effect on the Company's business, financial condition 
and results of operations.

COMPETITION

     Competition in the market for products that diagnose and monitor bone 
and other connective tissue diseases and disorders is intense and expected to 
increase. The Company currently competes with other medical technology 
companies, biotechnology companies, pharmaceutical companies and research and 
academic institutions, both in the United States and abroad. Metra believes 
that its most significant competitors in the area of biochemical markers 
include Bio-Rad Laboratories, a life sciences company; DSL, a diagnostic 
company that in 1996 received 510(k) clearance from the FDA to market 
Osteometer's bone resorption product in the United States; IncStar, a 
diagnostic company; Corning Nichols Institute, a research laboratory and 
diagnostic company; Orion, a diagnostic and pharmaceutical company in 
Finland; Osteometer, a diagnostic company in Denmark; Hybritech, a division 
of Beckman 


                                       22


<PAGE>


Instruments, a diagnostic company that in 1996 received 510(k) clearance from 
the FDA to market its test for bone-specific alkaline phosphatase for the 
management of osteoporotic patients; and Ostex International, Inc., a 
diagnostic company that in 1995 received 510(k) clearance from the FDA to 
market an immunoassay for in vitro (clinical) diagnostic use. In addition, 
the Company will compete with companies that measure the same biochemical 
markers as Metra using different testing methods. The most established of 
these are companies manufacturing HPLC assays, including Corning Nichols 
Institute and Bio-Rad Laboratories. The Company believes that although the 
HPLC method for measuring pyridinium crosslinks is extremely accurate, it is 
primarily a research tool and is unsuitable for routine clinical use because 
it has low throughput, is expensive and labor intensive, and requires skilled 
technicians. There can be no assurance, however, that competitors have not 
developed, or are not developing, less expensive, more clinically useful HPLC 
products. In addition, as the Company licenses its technology to diagnostic 
companies for use in alternative formats, tests sold by these licensees will 
compete with the Company's products. 

     Certain diseases and disorders targeted by the Company's products can 
also be diagnosed and monitored using existing imaging technologies, such as 
DEXA. Although DEXA may be considered more expensive and less convenient than 
tests for biochemical markers for routine diagnosis and monitoring of 
connective tissue diseases and disorders, there can be no assurance that 
competitors have not developed, or are not developing, less expensive, more 
clinically convenient imaging devices. The Company believes that, at least in 
their present forms, current imaging systems and tests for biochemical 
markers should be complementary tools because Metra's tests can identify a 
patient's rate of bone loss, as compared to imaging analysis, which measures 
a patient's existing bone mass. 

     The market for the Company's ultrasound product under development is 
expected to be highly competitive and subject to rapid technological change 
and evolving industry requirements and standards. The Company believes that 
these trends will continue into the foreseeable future. The Company's 
ultrasound-based diagnostic product currently under development could 
experience competition from companies with DEXA products, companies with 
biochemical markers, and makers of ultrasound systems. Several companies, 
including Aloka Company Ltd., Hitachi Instruments, Inc., Hologic, Inc., Lunar 
Corporation, Norland Medical Systems and Osteometer MediTech AS have 
developed systems to measure bone density which could compete with the 
Company's ultrasound product under development. The Company believes that 
competition in the field of bone densitometry is based upon price, precision, 
speed of measurement, patient radiation dose, size and ease of operation, 
product versatility, product reliability and quality of service. There can be 
no assurance that the Company's product, if commercialized, will compete 
effectively with respect to these criteria. 

     Several companies, including Hologic, Inc., IGEA S.r.l., McCue PLC, 
Lunar Corporation, Myriad Ultrasound Systems, Ltd., and Osteometer MediTech 
AS, have developed ultrasound systems to assess bone fragility. All 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, size and ease of operation, product reliability and quality of 
service. No ultrasound bone analyzer has been approved for commercial sale in 
the United States. If the Company's competitors obtain FDA clearance or 
approval for ultrasound bone analyzers in the United States before the 
Company, it could have a material adverse effect on the Company's ability to 
introduce its ultrasound device (if developed), which in turn could have a 
material adverse effect on the Company's business, financial condition and 
results of operations. 

     In addition, other companies have developed ultrasound technology for 
uses unrelated to measurement of bone characteristics. There can be no 
assurance that such companies will 


                                       23


<PAGE>


not successfully adapt their technology to the bone field, and obtain 
significant market share. The entry of such companies into the market for the 
Company's ultrasound product under development could have a material adverse 
effect on its business, financial condition and results of operations. 

     Many of the Company's competitors have substantially greater financial, 
technical and human resources than the Company. In addition, many of these 
competitors have substantially greater experience than the Company in 
research and development, undertaking clinical trials, obtaining regulatory 
approvals and third-party reimbursement and manufacturing, marketing and 
selling diagnostic products. Smaller companies may also prove to be 
significant competitors, particularly through collaborative arrangements with 
larger companies. Furthermore, academic institutions, governmental agencies, 
and other public and private research organizations conduct research, seek 
patent protection and establish collaborative arrangements for product 
development and marketing and therefore could become significant competitors. 

     A number of diagnostic tests and procedures for measure of bone 
metabolism and other connective tissue diseases and disorders currently exist 
and others are in development by other companies. These products, as well as 
products that may be developed in the future, may be available for sale prior 
to the Company's products, or at a lower cost, or with better technical 
characteristics, rendering the Company's products less competitive or 
obsolete. In addition, as the Company licenses its technology to diagnostic 
companies for use in alternative formats, tests sold by these licensees will 
compete with the Company's products. Any product that the Company succeeds in 
developing and for which it gains regulatory approval must then compete for 
market acceptance and market share. There can be no assurance that 
competitors' products will not be found more competitive, either for general 
use or in specific applications such as patients with particular medical 
conditions, or those who are receiving certain therapies. The Company 
believes that for all of its immunoassay products important competitive 
factors include the relative speed with which companies can develop products, 
establish clinical utility, complete the clinical testing and regulatory 
approval processes, obtain reimbursement and supply commercial quantities of 
the product to the market. The Company's inability to compete favorably with 
respect to any of these factors could have a material adverse effect on its 
business, financial condition and results of operations. 

PATENTS, PROPRIETARY RIGHTS AND RELATED LITIGATION RISKS

     The Company's success will depend in part on its ability to obtain 
patent protection for its products and processes, to preserve its trade 
secrets and to operate without infringing the proprietary rights of third 
parties. The Company owns five United States patents, 15 pending United States 
patent applications, and corresponding foreign patent applications, all in 
the area of medical diagnostics. 

     The Company is the exclusive licensee from The Rowett Research Institute 
in Scotland of patents and patent applications directed to certain diagnostic 
methods of detecting metabolic bone disorders, including a United States 
patent, six pending United States patent applications, two European Patent 
Office patents, a related Australian patent, a related Canadian patent and 
ten related foreign patent applications. The Company pays The Rowett Research 
Institute royalties upon sales of the Company's Pyrilinks products. 

     The Company's ability to protect its proprietary position is in part 
dependent on the issuance of patents on current and future applications. The 
Company currently has applications pending in the United States, Europe, 
Japan, Canada and Australia. The validity and breadth of claims covered in 
medical technology patents involve complex legal and factual questions, and 


                                       24


<PAGE>


therefore, are highly uncertain. Patent applications covering the technology 
underlying the Company's products that have received 510(k) clearances from 
the FDA have not been issued (other than a European patent covering the 
technology underlying the Company's Pyrilinks products), and no assurance can 
be given that such and other pending patent applications or any future patent 
applications will be issued, that the scope of any patent protection will 
exclude competitors or provide competitive advantages to the Company, that 
any of the Company's patents will be held valid if subsequently challenged or 
that others will not claim rights in or ownership to the patents and other 
proprietary rights held by the Company. The failure of the Company to obtain 
issuances of patents that cover the technology underlying the Company's 
products that have received 510(k) clearances from the FDA, or any other 
outstanding patent applications, could have a material adverse effect on the 
Company's business, financial condition and results of operations. 
Furthermore, there can be no assurance that others have not developed or will 
not develop similar products, duplicate any of the Company's products or 
design around the Company's patents. In addition, others may hold or receive 
patents or file patent applications that contain claims having a scope that 
covers products developed by the Company. In the event that any relevant 
claims of third-party patents are upheld as valid and enforceable, the 
Company could be prevented from practicing the subject matter claimed in such 
patents or could be required to obtain licenses from the patent owners of 
each of such patents or to redesign its products or processes to avoid 
infringement. There can be no assurance that such licenses would be available 
or, if available, would be on terms acceptable to the Company or that the 
Company would be successful in any attempt to redesign its products or 
processes to avoid infringement. The Company also relies upon unpatented 
trade secrets to protect its proprietary technology, and no assurance can be 
given that others will not independently develop or otherwise acquire 
substantially equivalent techniques or otherwise gain access to the Company's 
proprietary technology or that the Company can ultimately protect meaningful 
rights to such unpatented proprietary technology. 

     There has been substantial litigation regarding patent and other 
intellectual property rights in the medical device industry. Litigation, 
which would result in substantial cost to and diversion of effort by the 
Company, may be necessary to enforce patents issued to the Company, to 
protect trade secrets or know-how owned by the Company, to defend the Company 
against claimed infringement of the rights of others or to determine the 
ownership, scope or validity of the proprietary rights of the Company and 
others. An adverse determination in any such litigation could subject the 
Company to significant liability to third parties, could require the Company 
to seek licenses from third parties, which licenses may not be available or, 
if available, may not be on terms acceptable to the Company, and ultimately 
could prevent the Company from manufacturing, selling or using its products, 
any of which could have a material adverse effect on the Company's business, 
financial condition and results of operations. 

     Metra also relies on trade secrets and proprietary know-how in its 
manufacturing processes. The Company requires each of its employees, 
consultants and advisors to execute a confidentiality agreement upon the 
commencement of any employment, consulting or advisory relationship with the 
Company. Each agreement provides that all confidential information developed 
or made known to the individual during the course of the relationship will be 
kept confidential and not disclosed to third parties except in specified 
circumstances. In the case of employees, the agreements provide that all 
inventions conceived of by an individual shall be the exclusive property of 
the Company, other than inventions unrelated to the Company and developed 
entirely on the employee's own time. There can be no assurance, however, that 
these agreements will provide meaningful protection or adequate remedies for 
misappropriation of the Company's trade secrets in the event of unauthorized 
use or disclosure of such information.

REIMBURSEMENT

     The Company's ability to successfully commercialize its products depends 
in part on the availability of, and the Company's ability to obtain, adequate 
levels of third-party reimbursement for use of its diagnostic tests. Although 
the Company's products are available for clinical use in certain European 
countries, reimbursement is currently available in only certain of those 
countries. 

     In the United States, the Company has received FDA clearance for 
Alkphase-B, Pyrilinks and Pyrilinks-D. Reimbursement for the Company's FDA 
cleared tests is determined by CPT codes and may vary by state. Reimbursement 
under a specific CPT code is available for Alkphase-B, and the Company has 
been informed that a specific CPT code to enable reimbursement in the United 
States for its bone resorption tests, Pyrilinks and Pyrilinks-D, will be 
published in January 1997. In the United States, the cost of medical care is 
funded, in substantial part, by government insurance programs, such as 
Medicare and Medicaid, and private and corporate health insurance plans. 
Third-party payors may deny reimbursement if they determine that a prescribed 
device has not received appropriate FDA or other governmental regulatory 
clearances, is not used in accordance with cost-effective treatment methods 
as determined by the payor, or is experimental, unnecessary or inappropriate. 
The Company's ability to commercialize its products successfully will depend 
in part on the extent to which appropriate reimbursement levels for the cost 
of such products and related treatment are obtained from government 
authorities, private health insurers and other organizations, such as health 
maintenance and organizations ("HMOs"). Third-party payors are increasingly 
challenging the prices charged for medical products and services. Also, the 
trend towards managed health care in the United States and the concurrent 
growth of organizations such as HMOs, which could control or significantly 
influence the purchase of health care services and products, as well as 
legislative proposals to reform health care or reduce government insurance 
programs, may all result in lower prices for the Company's products. The cost 
containment measures that health care providers are instituting and the 
impact of any health care reform could have an adverse effect on the 
Company's ability to sell its products and may have a material adverse effect 
on the Company's business, financial condition and results of operations. 

     There can be no assurance that reimbursement in the United States or 
foreign countries will be available for any of the Company's products, or if 
available, will not be decreased in the future, or that reimbursement amounts 
will not reduce the demand for, or the price of, the Company's products. The 
unavailability of third-party reimbursement or the inadequacy of the 
reimbursement for medical procedures using the Company's tests could have a 
material adverse effect on the Company's business, financial condition and 
results of operations. Moreover, the Company is unable to forecast what 
additional legislation or regulation, if any, relating to the health care 
industry or third-party coverage and reimbursement may be enacted in the 
future or what effect such legislation or regulation would have on the 
Company's business. 

GOVERNMENT REGULATION

     The manufacturing, testing, labeling, distribution, marketing, 
advertising and promotion of the Company's products are subject to extensive 
and rigorous regulation by the FDA and, to varying degrees of regulation, by 
state and foreign regulatory agencies. The Company's products are regulated 
by the FDA under the Federal Food, Drug and Cosmetic Act (the "Act"), as 
amended by the Medical Device Amendments of 1976 and the Safe Medical Devices 
Act of 1990, among other laws. Under the Act, the FDA regulates the clinical 
testing, manufacturing, labeling, distribution, sale, advertising and 
promotion of medical devices in the United States. In addition, various 
foreign countries in which the Company's products are or may be sold, 
including, Germany, France, Japan and Canada, impose local regulatory 


                                       26


<PAGE>


requirements. The testing for, preparation of and subsequent FDA and foreign 
regulatory review of required applications is expensive, lengthy and 
uncertain. Failure to comply with FDA and similar foreign requirements could 
result in civil monetary penalties or criminal sanctions, restrictions on or 
injunction against marketing of the Company's products, as well as seizure or 
recall of the Company's products, or other regulatory action. There can be no 
assurance that the Company will be able to obtain necessary regulatory 
approvals or clearances on a timely basis or at all, and delays in receipt of 
or failure to receive such approvals or clearances, the loss or limitation of 
previously received approvals or clearances, adoption of future regulations 
which may further restrict the production or sales of the Company's products, 
or failure to comply with existing or future regulatory requirements would 
have a material adverse effect on the Company's business, financial condition 
and results of operations. 

     The Act, among other things, classifies medical devices into three 
categories over which the FDA maintains increasing levels of regulation: 
Class I (general controls), II (special controls) and III (premarket 
approval). Although most devices new to the marketplace after May 1976 are 
automatically classified as Class III, the Company believes that the majority 
of Metra's products will ultimately be classified as Class I or II devices 
and hence, not subject to the requirement of premarket approval by the FDA. 
Prior to marketing any of these devices, the Company is required to submit a 
510(k) premarket notification to the FDA and await the FDA's determination 
that the product may be marketed. In any 510(k) premarket notification the 
Company must, among other things, demonstrate the product to be marketed is 
substantially equivalent in performance, formula, design and intended use to 
a legally marketed Class I or Class II predicate device or to a Class III 
device for which the FDA has not required premarket approval. Test data from 
clinical trials may be required to demonstrate substantial equivalence and 
that the products are safe and effective, which may delay the 510(k) 
premarket notification review period. 

     Following submission of a 510(k) premarket notification, a company may 
not market the device for clinical use until an order is issued by the FDA 
finding the product to be substantially equivalent. The FDA has no specific 
time limit by which it must respond to a 510(k) premarket notification. The 
FDA may agree that the product is substantially equivalent to a predicate 
device and allow the product to be marketed in the United States. The FDA, 
however, may (i) determine that the new device is not substantially 
equivalent and require a premarket approval application ("PMA"), or (ii) 
require further information, such as additional test data, including data 
from clinical studies, before it is able to make a determination regarding 
substantial equivalence. By requesting additional information the FDA can 
further delay market introduction of a Company's products. 

     In August 1995, Metra received FDA clearance of its 510(k) premarket 
notification for Alkphase-B for use as an aid in the management of patients 
diagnosed with Paget's disease. In November 1995, Metra received FDA 
clearance of its 510(k) premarket notification for Pyrilinks Polyclonal and 
Pyrilinks as measures of type I collagen degradation, especially bone 
collagen. In December 1995, Metra received FDA clearance of its 510(k) 
premarket notification for Pyrilinks-D as a measure of bone resorption. 

     There can be no assurance that the FDA will act favorably or quickly in 
its review of the Company's future 510(k) submissions, if any, and 
significant difficulties and costs may be encountered by the Company in its 
efforts to obtain FDA clearance that could delay or preclude the Company from 
selling its products in the United States. Furthermore, there can be no 
assurance that the FDA will not request additional data, require that the 
Company conduct further clinical studies or require a PMA, causing the 
Company to incur further cost and delay. In addition, there can be no 
assurance that the FDA will not limit the intended use of the Company's 
products as a condition of 510(k) clearance or PMA approval. Further, if a 


                                       27


<PAGE>


company wishes to propose modifications to a product after FDA clearance of a 
510(k) premarket notification or approval of a PMA, including changes in 
indications or other significant modifications to labeling or manufacturing, 
additional clearances or approvals will be required from the FDA. Failure to 
receive or delays in receipt of FDA clearances or approvals, including the 
need for extensive clinical trials or additional data as a prerequisite to 
approval, or any FDA limitations on the intended use of the Company's 
products, could have a material adverse effect on the Company's business, 
financial condition and results of operations. 

     If the FDA indicates that a PMA is required for any of the Company's 
products, the application will require the results of extensive clinical 
studies, manufacturing information and likely review by a panel of experts 
outside the FDA. Clinical studies would need to be conducted in accordance 
with FDA requirements. Failure to comply with FDA requirements could result 
in the FDA's refusal to accept the data or the imposition of regulatory 
sanctions. FDA review of a PMA application can take significantly longer than 
that for a 510(k) premarket notification. There can be no assurance that the 
Company will be able to meet the FDA's PMA requirements or that any necessary 
approvals will be received. Failure to obtain necessary regulatory approvals, 
the restriction, suspension or revocation of regulatory approvals, if 
obtained, or any other failure to comply with regulatory requirements could 
have a material adverse effect on the Company's business, financial condition 
and results of operations.

     The Act and California laws also require the Company to be licensed and 
to manufacture its products in compliance with current good manufacturing 
practices ("GMP") regulations. These regulations require that the Company 
manufacture its products and maintain related documentation in a prescribed 
manner with respect to manufacturing, testing and control activities. The 
Company is also required to comply with various FDA requirements for labeling 
and marketing, and the FDA prohibits a device, whether or not cleared under a 
510(k) premarket notification or approved under a PMA, from being marketed 
for unapproved clinical uses. If the FDA believes that a company is not in 
compliance with the regulations, it can institute proceedings to detain or 
seize a product, issue a recall, prohibit marketing and sales of the 
company's products and assess civil and criminal penalties against the 
company, its officers or its employees. There can be no assurance that Metra 
will receive marketing clearance or approval for any of its future products 
or that its manufacturing facility will satisfy GMP or California 
manufacturing requirements. The Company's facilities and manufacturing 
processes have been periodically inspected by the State of California and 
other agencies, but remain subject to audit from time to time. The Company 
believes that it is in substantial compliance with all applicable federal and 
state regulations. Nevertheless, there can be no assurance that the FDA or a 
state agency will agree with the Company's position, or that its GMP 
compliance will not be challenged at some subsequent point in time. 
Enforcement of the GMP regulations has increased significantly in the last 
several years and the FDA has publicly stated that compliance will be more 
strictly scrutinized. In the event that the Company is determined to be in 
noncompliance with FDA regulations, to the extent that the Company is unable 
to convince the FDA or state agency of the adequacy of its compliance, the 
FDA or state agency has the power to assert penalties or remedies, including 
injunction or temporary suspension of shipment until compliance is achieved. 
Noncompliance may also lead to a recall of product. Such penalties or 
remedies could have a materially adverse effect on the Company's business, 
financial condition and results of operations. In addition, the manufacture, 
sale or use of the Company's products are also subject to regulation by other 
federal entities, such as the Occupational Safety and Health Agency and the 
Environmental Protection Agency, and by various state agencies, including the 
California Environmental Protection Agency. Federal and state regulations 
regarding the manufacture, sale or use of the Company's products are subject 
to future change, which changes could have a material adverse effect on the 
Company's business, financial condition and results of operations.


                                       28


<PAGE>


     Distribution of the Company's products outside the United States is 
subject to FDA export and extensive foreign government regulation. These 
regulations, including the requirements for approvals or clearance to market, 
the time required for regulatory review and the sanctions imposed for 
violations, vary from country to country. There can be no assurance that the 
Company will obtain regulatory approvals in such countries or that it will 
not be required to incur significant costs in obtaining or maintaining its 
foreign regulatory approvals. In addition, the export by the Company of 
certain of its products which have not yet been cleared for domestic 
commercial distribution may be subject to FDA export restrictions. Failure to 
obtain necessary regulatory approvals, the restriction, suspension or 
revocation of existing approvals or any other failure to comply with 
regulatory requirements outside the United States could have a material 
adverse effect on the Company's business, financial condition and results of 
operations. 

     Any of Metra's customers using its diagnostic devices for clinical use 
in the United States may also be regulated under the Clinical Laboratory 
Improvement Amendments of 1988 ("CLIA"). CLIA is intended to ensure the 
quality and reliability of all medical testing in laboratories in the U.S. by 
requiring that any health care facility in which testing is performed meet 
specified standards in the areas of personnel qualification, administration, 
participation in proficiency testing, patient test management, quality 
control, quality assurance and inspections. The regulations have established 
three levels of regulatory control based on test complexity _ "waived," 
"moderately complex" and "highly complex". Metra's Alkphase-B test is 
categorized as a highly complex test for clinical use in the United States, 
and the Company believes that its other tests will also be categorized as 
highly complex. Laboratories that perform either moderately or highly complex 
tests must meet certain standards with the major difference in requirements 
being quality control and personnel standards. Personnel requirements for 
highly complex tests are more rigorous than those for moderately complex 
tests, requiring that personnel have more education and experience than 
personnel conducting moderately complex tests. Under the CLIA regulations, 
all laboratories performing high or moderately complex tests are required to 
obtain either a registration certificate or certification of accreditation 
from the Health Care Financial Administration ("HCFA"). As a result of the 
CLIA requirements, physician office laboratories and small volume test sites 
may be dissuaded from initiating, continuing or expanding patient testing, 
particularly if the tests are classified as moderately or highly complex 
tests. There can be no assurance that the CLIA regulations and future 
administrative interpretations of CLIA will not have an adverse impact on the 
potential market for the Company's products. 

EMPLOYEES

     As of June 30, 1996, the Company had 86 full-time employees, 25 of whom 
were engaged in, or directly supported, the Company's research and 
development activities, 23 of whom were in domestic and international sales 
and marketing, 25 of whom were in manufacturing, and 13 of whom were in 
administration. The Company also employs several part-time employees and uses 
outside consultants. The Company considers relations with its employees to be 
good. None of the Company's employees is covered by a collective bargaining 
agreement. 

FACILITIES

     Metra currently leases approximately 31,000 square feet of laboratory 
and office space at two facilities in Mountain View, California.  The Company 
leases these facilities under operating leases which last through May 2001, 
each with a renewal option that, if exercised, would extend the term of the 
lease through May 2003.  In addition, the Company leases approximately 4,000 
square feet of office space in Beaverton, Oregon under an 


                                       29


<PAGE>


operating lease which lasts until July 7, 1997.  The Company believes that 
its existing facilities will be sufficient for its operational purposes 
through 1998.

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

OVERVIEW

    Since its commencement of operations in March 1990, Metra has been 
engaged in the development and commercialization of diagnostic products for 
the detection and management of metabolic bone diseases and disorders. The 
Company has developed and is currently marketing for research and clinical 
use four immunodiagnostic tests to measure bone resorption (loss) and 
formation and one immunodiagnostic test to detect certain pediatric growth 
disorders. In the United States, three of these tests have received 510(k) 
clearance from the FDA for clinical use and two of these tests are being 
marketed for research use only. The Company is currently marketing its 
products in Japan for research use only and for research as well as clinical 
use in numerous other countries, including Germany, Italy, Spain and the 
United Kingdom. 

     The Company's principal sources of revenue are product sales and partner 
revenues. Product sales are principally derived from sales of the Company's 
bone resorption and formation tests for research and clinical use. Partner 
revenues result from certain collaborative relationships and primarily 
consist of milestone payments and licensing fees received from these partners 
and revenues from sales to these partners of proprietary reagents for use 
with their test formats. 

     The Company's revenues from product sales have historically resulted 
from  international sales for clinical and research use and from sales in the 
United States for research use. In November and December of 1995, the Company 
received 510(k) clearance from the FDA for its Pyrilinks and Pyrilinks-D 
products. Revenues from clinical sales in the United States will be 
dependent, in part, upon the rate at which the Company can increase awareness 
and acceptance of its products among clinicians. The Company commenced its 
marketing efforts in the United States upon receiving 510(k) clearance, and 
does not anticipate significant revenues from clinical sales of its products 
in the United States unless and until the results of its marketing efforts 
are realized.  As a result of the significantly increased sales and marketing 
activities in the United States following receipt of the FDA clearances, the 
Company expects expenses associated with such activities to increase in 
future periods. There can be no assurance that the Company can successfully 
increase market awareness or acceptance of the Company's products in a timely 
manner or at all, and failure to do so would have a material adverse effect 
on the Company's business, financial condition and results of operations. 

     Historically, the Company's quarterly revenues have fluctuated 
significantly. Partner revenues have fluctuated primarily as a result of the 
timing of milestone payments received from corporate collaborations. Product 
sales have fluctuated primarily as a result of the introduction of new 
products, seasonal variations in demand, the rate of acceptance of the 
Company's products, and variations in the timing and volume of distributor 
purchases. The Company expects that its revenues will fluctuate as a result 
of these and other factors.   Such fluctuations may result in the Company 
failing to meet securities analysts' expectations, which could have a 
material adverse effect upon the market price of the Company's Common Stock.  
In June 1996 the Company announced that for the fourth quarter of 1996 and 
for fiscal 1997 its product sales would not meet securities analysts' 
expectations.  Subsequent to this announcement, the market price of the 
Company's Common Stock dropped from $11.00 to $7.00 on the first full day of 
trading after the announcement.  The Company expects that international sales 
will continue to account for a significant portion of its revenues in the 
future. Also, the Company expects to incur increased costs related to sales 
and marketing, clinical studies, manufacturing, research and development, 
general and administrative expenses and expansion of its facilities. As a 
result, the Company expects its results from operations will vary 
significantly from quarter to quarter and from year to year and will depend 
on, among other things, gaining regulatory clearances in the United States, 
Japan and elsewhere, the rate of acceptance of the Company's products in the 
marketplace, the availability of reimbursement, the timing of fees and 
milestone payments from its partners in collaborative relationships, the 
execution of new collaborative relationships, costs associated with the 
development of the Company's products and costs associated with and the 
financial impact of acquisitions, including the Company's recent acquisition 
of Osteo Sciences Corporation ("Osteo"). 

     Effective January 31, 1996, the Company completed the acquisition of 
Osteo, a company engaged in the development of a portable ultrasound product 
designed to assess bone fragility. The acquisition was accounted for as a 
purchase. As a result of the acquisition, the Company took a one time charge 
to

                                 35

<PAGE>

operations in the quarter ending March 31, 1996 related to acquired 
in-process research and development of approximately $11,291,000. This charge 
was primarily composed of the purchase price of approximately $10,017,000, 
with the balance related to costs and expenses associated with the 
acquisition, the fair value of liabilities assumed including reserves for 
future costs related to the acquisition, less the fair value of tangible 
assets acquired. Prior to the acquisition, research and development expenses 
constituted a significant percentage of the operating expenses incurred by 
Osteo. The Company intends to continue the research and development 
activities related to ultrasound technology at levels which exceed the level 
historically performed by Osteo. As a result, the Company expects that its 
research and development expenses will increase from the levels experienced 
prior to the acquisition. 

     The Company's gross margin is affected by a number of factors, including 
product mix, product pricing, the extent of diagnostic test sales compared to 
reagent sales and royalty revenue, the percentage of direct sales compared to 
distributor sales and manufacturing costs, including overhead and material 
costs. Due to seasonal factors such as customer and distributor vacations, 
the Company expects reduced product sales during the summer months, 
particularly in Europe. As a result of this seasonal effect, the Company's 
revenues could be lower in the quarters ending June 30 and September 30 than 
in the other quarters. 

     The manufacturing, testing, labeling, distribution, marketing, 
advertising and promotion of the Company's products are subject to extensive 
and rigorous government regulation in the United States and other countries. 
The Company can only commence marketing its products for clinical use after 
regulatory requirements are satisfied, thus, the Company's future product 
sales and profitability are uncertain. There can be no assurance that 
additional regulatory approvals will be obtained in a timely manner, if at 
all, and significant difficulties and costs that may be encountered by the 
Company in its efforts to obtain additional regulatory approvals could delay 
or affect the Company's ability to sell its products for clinical use in the 
United States or internationally. Inability to obtain regulatory approvals or 
any other failure to comply with the regulatory requirements could have a 
material adverse effect on the Company's business, financial condition and 
results of operations.

     The Company has limited experience in manufacturing its products and 
relies on key sources of supply for certain ingredients and other product 
components. If the Company experiences significant demand for its products, 
the Company will have to expend significant capital resources to develop 
large-scale manufacturing capabilities.

     Metra has established corporate partner relationships with a number of 
companies, including Sumitomo Pharmaceuticals Co., Ltd., Ciba Corning 
Diagnostics Corporation (a subsidiary of Chiron Corporation), Bayer 
Corporation, Diagnostic Products Corporation, and Abbott Laboratories. The 
Company expects to continue to rely on current and future collaborative 
relationships to develop products and to provide milestone, royalty and 
reagent-sales revenues. There can be no assurance that the Company will be 
able to negotiate acceptable agreements in the future, that such new 
agreements or existing agreements will be successful, or that the other 
parties to the agreements will not terminate such agreements or pursue 
alternative technologies.

     Competition in the market for the Company's diagnostic products from 
other medical technology companies, biotechnology companies, pharmaceutical 
companies and research and academic institutions both in the United States 
and abroad is intense and is expected to increase. Many of the Company's 
competitors have substantially greater financial, technical and human 
resources than the Company. In addition, many of these competitors have 
significantly greater experience than the Company in research and 
development, manufacturing, marketing and selling diagnostic products, 
undertaking clinical trials and obtaining regulatory approvals and 
third-party reimbursement. Developments involving competitors, including 
introduction of new diagnostic products and receipt of regulatory approvals, 
could have a material adverse effect on the Company's business, financial 
condition and results of operations.

     There has been substantial litigation regarding patent and other 
intellectual property rights in the medical device industry. Litigation, 
which would result in substantial cost to and diversion of effort by the 
Company, may be necessary to enforce patents issued to the Company, to 
protect trade secrets or know-how owned by the Company, to defend the Company 
against claimed infringement of the rights of others or to determine the 
ownership, scope or validity of the proprietary rights of the Company and 
others. An adverse determination in any such litigation could subject the 
Company to significant liability to third parties, could require the Company 
to seek licenses from third parties, which licenses may not be available or, 
if available,


                                    36
<PAGE>

may not be on terms acceptable to the Company, and ultimately could prevent 
the Company from manufacturing, selling or using its products, any of which 
could have a material adverse effect on the Company's business, financial 
condition and results of operations.

     The Company's ability to successfully commercialize its products depends 
in part on the availability of, and the Company's ability to obtain, adequate 
levels of third-party reimbursement for clinical use of its diagnostic tests. 
Although the Company's products are available for clinical use in certain 
European countries, reimbursement is currently available in only certain of 
those countries. In the United States, reimbursement is not available for 
research use only products. Reimbursement for the Company's FDA cleared tests 
is determined by CPT codes and may vary by state. In addition, reimbursement 
under a specific CPT Code is not currently available for the Company's 
Pyrilinks and Pyrilinks-D products. There can be no assurance that 
reimbursement in the United States or foreign countries will be available for 
any of the Company's products, or if available, will not be decreased in the 
future, or that reimbursement amounts will not reduce the demand for, or the 
price of, the Company's products. The unavailability of third-party 
reimbursement or the inadequacy of reimbursement for medical procedures using 
Metra's tests could have a material adverse effect on the Company's business, 
financial condition and results of operations.

RESULTS OF OPERATIONS

FISCAL YEARS ENDED JUNE 30, 1996 AND 1995

     Total revenues for the fiscal year ended June 30, 1996 increased to 
$6,470,000 from $3,296,000 for the year ended June 30, 1995.  The increase in 
total revenues resulted from the growing market acceptance of the Company's 
products coupled with increased partner revenues due to product approvals and 
associated milestone payments.

     Product sales for the year ended June 30, 1996 increased to $4,413,000 
from $2,552,000 for the year ended June 30, 1995.  The increase in product 
sales was due to broader acceptance of the Company's bone resorption tests 
for clinical use internationally and in the United States.   The Company's 
bone resorption products were cleared for marketing by the FDA in late 
calendar 1995.  International product sales accounted for 78% of product 
revenues for both the fiscal years ended June 30, 1996 and 1995.

     Partner revenues for the fiscal year ended June 30, 1996 increased to 
$2,057,000 from $744,000 for the fiscal year ended June 30, 1995.  This 
increase resulted primarily from an increase in non-recurring milestone 
payments from corporate partners, earned upon receipt of FDA clearance of 
Pyrilinks (November 1995) and Pyrilinks-D (December 1995), and to a lesser 
extent an increase in reagent sales to collaborative partners.

     Cost of product sales for the fiscal year ended June 30, 1996 increased 
to $3,276,000 from $1,987,000 for the fiscal year ended June 30, 1995, 
reflecting the increased volume of products sold and associated production 
costs.

     Research and development expenses for the fiscal year ended June 30, 
1996 increased to $4,308,000 from $3,717,000 for the fiscal year ended June 
30, 1995.  This increase resulted from the increased costs of the Company's 
internal product development programs, external collaborative efforts and the 
on-going research costs of the Ultrasound program which was acquired in 
January 1996 (Osteo Sciences Corporation).  The Company expects to increase 
its research and development expenditures during the next several years to 
continue to enhance and expand its product lines.

     Sales and marketing expenses for the fiscal year ended June 30, 1996 
increased to $7,725,000 from $2,881,000 for the fiscal year ended June 30, 
1995.  The increase is due to increased staffing in domestic and 
international locations, the costs of additional marketing programs being 
implemented to support the clinical launch of the Company's products in the 
United States following recent clearance by the FDA, and the addition of a 
direct sales force in the United States.  Sales and marketing expenditures 
are expected to increase significantly in the next several years as 
additional marketing programs and sales and marketing staff are added to 
support the expansion of the sales operations domestically and 
internationally.

     General and administrative expenses for the fiscal year ended June 30, 
1996 increased to $3,070,000 from $1,851,000 for the fiscal year ended June 
30, 1995, due to increased personnel costs and additional expenses


                                  37
<PAGE>

associated with being a public company.  The Company expects to increase its 
general and administrative expenditures during the next several years to 
support the Company's growth, when and if such growth occurs.

Acquired in-process research and development costs for the fiscal year ended 
June 30, 1996 resulted from a one-time charge of $11,291,000. This charge was 
primarily composed of the purchase price of approximately $10,017,000, with 
the balance related to costs and expenses associated with the acquisition, 
the fair value of liabilities assumed including reserves for future costs 
related to the acquisition, less the fair value of tangible assets acquired.

Net other income for the fiscal year ended June 30, 1996 increased to 
$1,801,000 from $337,000 for the fiscal year ended June 30, 1995 primarily as 
a result of the investment of the proceeds from the Company's initial public 
offering in July 1995 and the Company's follow-on offering in April 1996.

FISCAL YEARS ENDED JUNE 30, 1995 AND 1994

     Total revenues for the fiscal year ended June 30, 1995 decreased to $3.3 
million from $3.5 million for the year ended June 30, 1994. This decrease in 
total revenues reflects a decrease in partner revenues, which was offset in 
part by an increase in product sales. 

     Product sales for the fiscal year ended June 30, 1995 increased to $2.6 
million from $1.4 million for the year ended June 30, 1994. This increase in 
product sales was due to broader acceptance of the Company's bone resorption 
tests for research purposes and for clinical use internationally and, to a 
lesser extent, the introduction in January 1995 of a new product, Alkphase-B. 
International sales accounted for 78% and 72% of product revenues for the 
fiscal years ended June 30, 1995 and 1994, respectively. 

     Partner revenues for the fiscal year ended June 30, 1995 decreased to 
$744,000 from $2.0 million for the year ended June 30, 1994. This decrease 
resulted from a decline of $1.4 million in non-recurring licensing fees and 
milestone payments due to the timing of contracts with collaborative 
partners. The decline was partially offset by an increase of $113,000 in 
reagent sales to collaborative partners. 

     Cost of product sales for the fiscal year ended June 30, 1995 increased 
to $2.0 million from $1.5 million for the year ended June 30, 1994, 
reflecting primarily an increase in both the volume of products sold and, to 
a lesser extent, the cost of maintaining and expanding the Company's 
manufacturing operations and an increase in the reserve for inventory with a 
risk of expiration. 

     Research and development expenses for the fiscal year ended June 30, 
1995 increased to $3.7 million from $2.9 million for the year ended June 30, 
1994, due primarily to costs associated with additional clinical studies and, 
to a lesser extent, to additional costs associated with the Company's 
research and development program. 

     Sales and marketing expenses for the fiscal year ended June 30, 1995 
increased to $2.9 million from $1.4 million for the year ended June 30, 1994, 
due to increased costs associated with providing training and support to 
distributors, clinicians, physicians and other customers in international 
markets and due to increased staffing. 

     General and administrative expenses for the fiscal year ended June 30, 
1995 increased to $1.9 million from $1.5 million for the year ended June 30, 
1994, due to increased facilities expenses and personnel costs. General and 
administrative expenses for the year ended June 30, 1995 included $388,000 in 
compensation expense associated with stock option grants. 

     Net other income for the fiscal year ended June 30, 1995 increased to 
$337,000 from $165,000 for the year ended June 30, 1994, primarily as a 
result of the timing of receipt of cash from issuances of redeemable 
preferred stock by the Company and the associated interest income received on 
the investment of proceeds. 

FISCAL YEARS ENDED JUNE 30, 1994 AND 1993

     Total revenues for fiscal 1994 increased to $3.5 million from $2.7 
million for fiscal 1993. This increase in total revenues primarily reflects 
increased product sales for research use. 


                                       38

<PAGE>

     Product sales for fiscal 1994 increased to $1.4 million from $617,000 in 
fiscal 1993. This increase in product sales was due to the introduction 
during fiscal 1994 of three new products, Pyrilinks-D, Pyrilinks and 
Prolagen-C, and broader acceptance of two products that were introduced in 
fiscal 1993, Pyrilinks and NovoCalcin, both for research purposes and for 
clinical use in certain foreign countries. International sales accounted for 
72% and 68% of product revenues for the fiscal years ended June 30, 1994 and 
1993, respectively. 

     Partner revenues for fiscal 1994 decreased to $2.0 million from $2.1 
million for fiscal 1993. In fiscal 1994 these revenues included $1.8 million 
of licensing fees and milestone payments as well as $215,000 in reagent 
sales. In fiscal 1993, all partner revenues consisted of licensing fees and 
milestone payments. Revenues from two partners, Ciba Corning Diagnostics 
Corporation and Hybritech, Inc., constituted 16% and 13% of total revenues 
for fiscal 1994. 

     Cost of product sales for fiscal 1994 increased to $1.5 million from 
$1.2 million for fiscal 1993, reflecting primarily an increase in both the 
volume of products sold and, to a lesser extent, the cost of maintaining and 
expanding the Company's manufacturing operations. 

     Research and development expenses for fiscal 1994 decreased to $2.9 
million from $3.2 million for fiscal 1993. This decrease was due to a 
decrease in clinical studies expenses to $172,000 for fiscal 1994 from 
$677,000 for fiscal 1993. The increased clinical studies expenses in fiscal 
1993 were incurred in connection with the Company's initial FDA filing for 
Pyrilinks. Excluding clinical studies expenses, research and development 
expenses for fiscal 1994 increased to $2.7 million from $2.5 million for 
fiscal 1993. 

     Sales and marketing expenses for fiscal 1994 increased to $1.4 million 
from $930,000 for fiscal 1993, due to increased costs associated with 
providing training and support to distributors, clinicians, physicians and 
other customers in international markets and to increased staffing. 

     General and administrative expenses for fiscal 1994 increased to $1.5 
million from $1.0 million for fiscal 1993 due to increased staffing expenses. 

     Net other income for fiscal 1994 increased to $165,000 from $87,000 for 
fiscal 1993. This increase resulted primarily from the timing of receipt of 
cash from issuances of Redeemable Preferred Stock by the Company. 

LIQUIDITY AND CAPITAL RESOURCES

     The Company has financed its operations from inception primarily through 
the sale of preferred and common stock, payments related to collaborative 
research and development agreements, sales of the Company's diagnostic 
products for research and clinical use and, to a lesser extent, through 
equipment financing. In July 1995, the Company completed its initial public 
offering of 3,450,000 shares of common stock. All preferred stock was 
automatically converted into shares of common stock upon closing of the 
offering. The cash proceeds from the Company's initial public offering, net 
of underwriters discounts were $32,085,000. Total additional expenses 
associated with the offering were $727,000, resulting in net proceeds from 
the offering of $31,358,000.  In April, 1996, the Company had a follow-on 
offering of 2,300,000 shares of common stock. The cash proceeds from the 
Company's follow-on offering dated April 22, 1996, net of underwriters' 
discounts were $29,187,000.  Total additional expenses associated with the 
follow-on offering were $450,000, resulting in net proceeds to the Company 
from the follow-on offering of $28,737,000.

     As of June 30, 1996, Metra had $19,217,000 in cash and cash equivalents 
and $33,030,000 in investment securities for total cash resources of 
$52,247,000. During the fiscal year ended June 30, 1996 the Company's use of 
cash in operating activities was $10,730,000 compared to $5,830,000 for the 
fiscal year ended June 30, 1995. The increase in cash used in operating 
activities was primarily due to the increased net loss, higher accounts 
receivable and inventory balances and an increase in prepaid expenses.  These 
increases are in support of the Company's product launch of certain key 
products in the United States in fiscal 1996, and to a lesser extent, 
increased sales of products internationally.  Net cash used in investing 
activities was $35,081,000 and was primarily due to the purchase of 
investment securities with a portion of the proceeds of the initial public 
offering and the follow-on offering and the costs of expansion of the 
Company's facilities.

     The Company has historically utilized leasing arrangements to finance 
capital purchases. In December 1995, the Company entered into two new leasing 
arrangements to finance $2,750,000 of equipment and building improvements. As 
of June 30, 1996, $1,922,000 of the available lease lines were utilized and 
outstanding in conjunction with these leases. The leases are both classified 
as capital leases and expire in fiscal year 2000. Both leasing agreements 
include negative covenants which require an irrevocable letter of credit in 
the event of non-compliance of the covenants. 

     The Company's future capital requirements depend upon, among other 
things, the costs of research and development programs, the funding of 
clinical and regulatory related studies, the expansion of marketing and 
selling activities, costs involved in filing, prosecuting and enforcing 
patent claims, and the time and costs associated with obtaining regulatory 
approvals for future products. Funds may also be used for investments in, or 
acquisitions of, complementary businesses, products or technologies, in 
expanding the Company's manufacturing capacity or in improving its existing 
facilities. Although the Company believes that its current cash, cash 
equivalents and investment securities will be sufficient to meet the 
Company's operating expenses and capital requirements through fiscal 1998, 
the Company's future liquidity and capital requirements will depend on 
numerous factors, including regulatory actions by the FDA and other 
international regulatory bodies, market acceptance of its products, expansion 
of the Company's marketing and sales activities and the cost of intellectual 
property protection. The Company may, however, seek additional equity or debt 
financing to fund further expansion of its manufacturing capacity, or to fund 
other projects or acquisitions. The timing and amount of such capital 
requirements cannot be precisely determined at this time and will depend on a 
number of factors, including demand for the Company's products, product mix 
changes, industry conditions and competitive factors. There can be no 
assurance that if it becomes necessary to raise additional capital, that such 
capital will be available on acceptable terms, if at all.

                Notes to Consolidated Financial Statements
                          June 30, 1996 and 1995


(1)   THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      (a)   THE COMPANY

      Metra Biosystems, Inc. ("Metra" or the "Company") was incorporated on 
      March 21, 1990. Since the commencement of operations the Company has 
      been engaged in the development and commercialization of diagnostic 
      products for the detection and management of metabolic bone diseases 
      and disorders. 

      In December 1993, the Company incorporated a wholly-owned subsidiary, 
      Metra Biosystems (U.K.) Ltd., that is responsible for the 
      commercialization of Metra's products in Europe. In October 1995, the 
      Company opened a branch office of Metra Biosystems (U.K.) Ltd., Metra 
      Biosystems (Italy) Ltd., that is responsible for the commercialization 
      of Metra's products in Italy. 

      In July 1995, the Company consummated its initial public offering of 
      its common stock resulting in the issuance of 3,450,000 shares of 
      common stock to the public at $10.00 per share. Net proceeds received 
      from the offering were approximately $31,358,000. In April 1996, the 
      Company issued another 2,300,000 shares of common stock in a follow-on 
      offering at $13.50 per share. Net proceeds received from this second 
      offering were approximately $28,737,000.

      (b)  DEVELOPMENTAL STAGE ENTERPRISE

      For the year ended June 30, 1994, the Company was considered to be in 
      the development stage and was engaged principally in research and 
      development activities. As of June 30, 1995, the Company was no longer 
      considered to be a developmental stage enterprise as principal 
      operations had commenced. 

      (c)  PRINCIPLES OF CONSOLIDATION

      The consolidated financial statements include the accounts of the 
      Company and its wholly-owned subsidiaries. All significant intercompany 
      balances and transactions have been eliminated in consolidation. The 
      operations of Osteo Sciences Corporation are included in the Company's 
      results of operations beginning February 1, 1996.

      (d)  CASH AND CASH EQUIVALENTS

      The Company considers all highly liquid debt instruments purchased with 
      an original maturity of less than 90 days to be cash equivalents. 

      (e)  INVENTORIES

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

      (f)  PROPERTY AND EQUIPMENT

      Property and equipment are stated at cost. Depreciation is provided 
      using the straight-line method over the estimated useful lives of the 
      respective assets, generally three to five years. Assets under capital 
      leases and leasehold improvements are amortized using the straight-line 
      method over the shorter of the lease term or the estimated useful lives 
      of the related assets.

            Notes to Consolidated Financial Statements, continued
                          June 30, 1996 and 1995


      (g)  INTANGIBLE ASSETS

      Included in other assets for the year ended June 30, 1995 were 
      intangible assets consisting primarily of licensed technology. 
      Intangible assets have been amortized on a straight-line basis over the 
      estimated useful lives of the assets, primarily eight years. 

      The Company assesses the recoverability of intangible assets by 
      determining whether the amortization of the asset's balance over its 
      remaining life can be recovered through projected undiscounted future 
      cash flows. Intangible assets are expensed if the Company determines 
      that the amortization of the asset's balance will not be recovered 
      through projected future cash flows. Intangible assets related to 
      acquired in-process research and development are expensed when incurred.

      (h)  PARTNER REVENUE
 
      Partner revenue consists principally of milestone payments, licensing 
      fees and proceeds from sales of reagents to collaborative partners for 
      research purposes.

      (i)  INCOME TAXES

      The Company accounts for income taxes under the Financial Accounting 
      Standards Board issued Statement of Financial Accounting Standards 
      (SFAS) No. 109, "Accounting for Income Taxes." SFAS No. 109 requires an 
      asset and liability approach for the financial reporting of income 
      taxes. Under SFAS No. 109, deferred tax assets and liabilities are 
      recognized for the future tax consequences attributable to differences 
      between the financial statement carrying amounts of existing assets and 
      liabilities and their respective tax bases and operating loss and tax 
      credit carryforwards. Deferred tax assets and liabilities are measured 
      using enacted tax rates expected to apply to taxable income in the 
      years in which those temporary differences are expected to be recovered 
      or settled. Under SFAS No. 109, the effect on deferred tax assets and 
      liabilities of a change in tax rates is recognized in income in the 
      period that includes the enactment date. 

      (j)  MARKETING COSTS

      All costs related to marketing and advertising the Company's products 
      are expensed in the period incurred.

      (k)  FOREIGN CURRENCY

      Foreign currency transactions and financial statements are translated 
      into U.S. dollars at current rates, except that revenue, costs and 
      expenses are translated at average rates during each reporting period. 
      Gains and losses resulting from foreign currency transactions and 
      intercompany balances expected to be paid in the foreseeable future are 
      included in results of operations. Gains and losses resulting from 
      translation of financial statements are excluded from results of 
      operations and are reflected as a cumulative translation adjustment, 
      which is reported as part of shareholders' equity (deficit). Translation 
      and transaction gains and losses for the years ended June 30, 1996, 1995 
      and 1994 were insignificant.

      (l)  STOCK SPLIT

      In April 1995, the Company's Board of Directors approved a one-for-six 
      reverse split of the Company's common and preferred stock. All 
      references in the accompanying financial statements to the number of 
      shares of common stock and per share amounts have been retroactively 
      restated to reflect this stock split.

            Notes to Consolidated Financial Statements, continued
                          June 30, 1996 and 1995


      (m)  REVENUE RECOGNITION

      Revenue from development contracts is recognized as the relevant 
      technical milestones are attained. Revenue from product sales is 
      recognized upon product shipment when title passes to the buyer. 

      (n)  NET LOSS PER SHARE

      Except as noted below, net loss per share is computed using the 
      weighted average number of shares of common stock outstanding. Common 
      equivalent shares from stock options and warrants are excluded from the 
      computation as their effect is anti-dilutive, except that, pursuant to 
      the Securities and Exchange Commission Staff Accounting Bulletin No. 
      83, common stock issued for consideration below the Company's initial 
      public offering (IPO) price and stock options granted with exercise 
      prices below the IPO price during the 12-month period preceding the 
      date of the initial filing of the Registration Statement, even when 
      anti-dilutive, have been included in the calculation of common 
      equivalent shares for periods prior to the closing of the Company's 
      IPO, using the treasury stock method based on the initial public 
      offering price, as if they were outstanding for all periods presented. 

      Furthermore, pursuant to Securities and Exchange Commission staff 
      policy, common equivalent shares from convertible preferred stock and 
      warrants that were converted upon the completion of the Company's IPO 
      are included (using the as if-converted method) for periods prior to 
      the closing of the Company's IPO. 

      (o)  MAJOR CUSTOMERS AND CONCENTRATIONS OF CREDIT RISK

      Financial instruments which potentially expose the Company to 
      concentrations of credit risk consist primarily of trade accounts 
      receivable. As of June 30, 1996, approximately 14% of recorded trade 
      receivables were concentrated with one customer. As of June 30, 1995, 
      approximately 22% of recorded trade receivables were concentrated with 
      two customers. To reduce credit risk, the Company performs ongoing 
      credit evaluations of its customers' financial condition. The Company 
      does not generally require collateral on credit sales to its customers. 

      The Company earns revenues primarily through product sales through 
      distributors and through collaborative agreements with partners. 
      Revenues from one corporate partner constituted 16%, 13% and 29% of 
      total revenues for the years ended June 30, 1996, 1995 and 1994, 
      respectively. Revenues from two corporate collaborators constituted 16% 
      and 13%, respectively, of total revenues for the year ended June 30, 
      1994. Product revenues from two distributors constituted 12% and 11%, 
      respectively, of total revenues for the year ended June 30, 1995. 
      Product revenues from one customer constituted 12% of total revenues 
      for the year ended June 30, 1996.

      (p)  USE OF ESTIMATES

      The Company's management has made a number of estimates and assumptions 
      relating to the reporting of assets and liabilities and revenues and 
      expenses and the disclosure of contingent liabilities to prepare these 
      financial statements in conformity with generally accepted accounting 
      principles. Actual results could differ from those estimates.

      (q)  RECLASSIFICATIONS

      Certain reclassifications have been made to the 1995 and 1994 financial 
      statements to conform to the 1996 presentation.

(2)   FINANCIAL INSTRUMENTS

      (a)  MARKETABLE SECURITIES

      In accordance with the requirements of SFAS 115, the Company has 
      classified its investments in certain debt and equity securities as 
      "available-for-sale." Such investments are recorded at fair value, as 
      determined by quoted market values as of June 30, 1996 and 1995, with 
      unrealized gains and losses, deemed by the Company as temporary in 
      nature, reported as a separate component of shareholders' equity 
      (deficit). There were no sales of investments during 1996, 1995 or 1994.

      Available-for-sale securities consisted of the following at June 30:

      value common stock. Since inception, 289,165 shares of common stock 
      have been issued to certain individuals under stock purchase agreements 
      that permit the Company to repurchase, at the original issuance price, 
      a portion of such shares in the event an individual shareholder ceases 
      to be associated with the Company. The shares subject to repurchase 
      generally expire on a pro-rata basis over a four-year period. As of 
      June 30, 1996 and 1995, there were approximately 51,563 and 85,522 
      shares, respectively, subject to repurchase. 

      (b)  PREFERRED STOCK

      Effective upon the closing of the Company's IPO, which occurred in July 
      1995, the Board of Directors received the authority to issue up to 
      5,000,000 shares of $0.001 par value preferred stock, to determine the 
      powers, preferences and rights and the qualifications, limitations or 
      restrictions granted to or imposed upon any unissued series of 
      undesignated preferred stock and to fix the number of shares 
      constituting any series and the designation of such series, without any 
      further vote or action by the Company's shareholders. No shares were 
      issued or outstanding at June 30, 1996.

(10)  STOCK OPTION PLANS

      (a)  1990 INCENTIVE STOCK PLAN

      The Company has reserved 700,000 shares for issuance under its 1990 
      Incentive Stock Plan (the Stock Plan) which provides for stock options 
      to be granted to employees (including consultants, officers, and 
      directors). The term of a stock option may not exceed 10 years. Options 
      granted to each employee under the Stock Plan generally become 
      exercisable at the rate of 12.5% of the total number of shares subject 
      to the options after the six month period from the date of grant, and 
      approximately 2% each month thereafter subject to continued service to 
      the Company. The exercise price of all incentive stock options granted 
      under the Stock Plan must be at least equal to the fair market value of 
      the common stock of the Company on the date of grant. The exercise 
      price of all nonstatutory stock options must equal at least 85% of the 
      fair market value of the common stock on the date of grant. The 
      exercise price of any incentive stock option granted to an optionee who 
      owns stock possessing more than 10% of the voting power of all classes 
      of stock of the Company's outstanding capital stock must equal at least 
      110% of the fair market value of the common stock on the date of grant. 
      Payment of the exercise price may be made in cash, promissory notes, 
      common stock of the Company owned by the optionee for more than six 
      months or other consideration as determined by the Board of Directors 
      or a committee of the Board. 

      The Company has recorded deferred compensation of $575,000 related to 
      certain of the Company's common stock options granted for the year 
      ended June 30, 1995 under the Stock Plan. This amount is being 
      amortized over the relevant period of benefit. For the years ended June 
      30, 1996 and 1995, $108,000 and $388,000, respectively, was amortized

      70,086 shares, respectively, had vested. Also, see note 18.

      Upon adoption of the Company's 1995 Stock Option Plan, the Company's 
      Board of Directors determined to make no further grants under the 1990 
      Incentive Stock Plan.

      (b)  1995 STOCK OPTION PLAN

      The Company's 1995 Stock Option Plan (the 1995 Option Plan) was adopted 
      by the Board of Directors in April 1995 and was approved by the 
      Company's shareholders in June 1995. An aggregate of 1,000,000 shares 
      of the Company's common stock are reserved for issuance under the 1995 
      Option Plan.  The 1995 Option Plan provides for the granting to 
      employees (including officers and employee directors) of incentive 
      stock options and for the granting to employees and consultants of 
      nonstatutory stock options. The 1995 Option Plan may be administered by 
      the Board of Directors or a committee of the Board (the Administrator). 
      The Administrator determines the terms of options granted under the 
      1995 Option Plan, including the number of shares subject to the option, 
      exercise price, term and exercisability. The exercise price of all 
      incentive stock options granted under the 1995 Option Plan must be at 
      least equal to the fair market value of the common stock of the Company 
      on the date of grant. The exercise price of any incentive stock option 
      granted to an optionee who owns stock representing more than 10% of the 
      voting power of the Company's outstanding capital stock must equal at 
      least 110% of the fair market value of the common stock on the date of 
      grant. Payment of the exercise price may be made in cash, promissory 
      notes or other consideration as determined by the Administrator. The 
      Administrator determines the term of options. With respect to any 
      participant who owns stock possessing more than 10% of the voting power 
      of all classes of stock of the Company, the maximum term of the option 
      must not exceed five years. The term of all other options may not 
      exceed ten years. If not terminated earlier, the 1995 Option Plan will 
      terminate in 2005. The Administrator has the authority to amend or 
      terminate the 1995 Option Plan as long as such action does not 
      adversely affect any outstanding option.

      (c)  1995 DIRECTOR STOCK OPTION PLAN

      The 1995 Director Stock Option Plan (the Directors' Plan) was adopted 
      by the Board of Directors in April 1995 and was approved by the 
      Company's shareholders in June 1995. A total of 200,000 shares of 
      common stock has been reserved for issuance under the Directors' Plan. 
      The Directors' Plan provides for the grant of nonstatutory stock 
      options to nonemployee directors of the Company. The Directors' Plan 
      provides that each person who is a nonemployee director of the Company 
      on the date of the Company's IPO and each person who first becomes a 
      nonemployee director of the Company after the date of the Company's IPO 
      shall be granted a nonstatutory stock option to purchase 10,000 shares 
      of common stock (the First Option) on the effective date of the 
      Company's IPO or on the date on which the optionee first becomes a 
      nonemployee director of the Company. Thereafter, on the date of each 
      annual meeting of the Company's shareholders at which such director is 
      elected, each such nonemployee director shall be granted an additional 
      option to purchase 5,000 shares of common stock (a Subsequent Option) 
      if, on such date, he or she shall have served on the Company's Board of 
      Directors for at least six months. The Directors' Plan provides that 
      the First Option shall become exercisable in installments as to 25% of 
      the total number of shares subject to the First Option on each of the 
      first, second, third and fourth anniversaries of the date of grant of 
      the First Option; each Subsequent Option shall become exercisable in 
      full on the first anniversary of the date of grant of that Subsequent 
      Option. The exercise price of all stock options granted under the 
      Directors' Plan shall be equal to the fair market value of a share of 
      the Company's common stock on the date of grant of the option. Options 
      granted under the Directors' Plan have a term of ten years. 

      In connection with the Company's IPO becoming effective on June 30, 
      1995, options to purchase 70,000 shares of common stock at an exercise 
      price of $10.00 per share were granted under the Directors' Plan.

      (d)  1995 EMPLOYEE STOCK PURCHASE PLAN

      The Company's 1995 Employee Stock Purchase Plan (the Purchase Plan) was 
      adopted by the Board of Directors in April 1995 and was approved by the 
      shareholders in June 1995. A total of 200,000 shares of common stock 
      has been reserved for issuance under the Purchase Plan. The Purchase 
      Plan will be implemented by two six-month offering periods each year. 
      The Purchase Plan will be administered by the Board of Directors or by 
      a committee appointed by the Board. Employees (including officers and 
      employee directors) of the Company, or of any majority owned subsidiary 
      designated by the Board, are eligible to participate if they are 
      customarily employed by the Company or any such subsidiary for at least 
      20 hours per week and more than five months per year. The Purchase Plan 
      permits eligible employees to purchase common stock through payroll 
      deductions, which may not exceed 5% of an employee's compensation, at a 
      price equal to the lower of 85% of the fair market value of the 
      Company's common stock at the beginning or end of the offering period. 
      Common stock purchased under the Purchase Plan must be held for a 
      period of six months before it may be sold. Employees may end their 
      participation in the offering at any time during the offering period, 
      and participation ends automatically on termination of employment with 
      the Company. 

      As of June 30, 1996, 19,114 shares had been purchased under the Purchase
      Plan.

      (e)  FUTURE ADOPTION OF NEW ACCOUNTING STANDARD

      The Financial Accounting Standards Board recently issued SFAS No. 123, 
      Accounting for Stock-Based Compensation. This statement establishes 
      financial accounting and reporting standards for stock-based employee 
      compensation plans, including employee stock purchase plans and stock 
      option plans. Adoption of SFAS No. 123 is required for fiscal years 
      beginning after December 15, 1995. Management plans to remain on APB 
      No. 25, Accounting for Stock Issued to Employees, for purposes of 
      measurement of compensation expense. Therefore, adoption of SFAS No. 
      123 will not have a material effect on the Company's consolidated 
      results of operations.

      (f)  NOTES RECEIVABLE FROM SHAREHOLDERS

      At June 30, 1996, the Company had two notes receivable outstanding from 
      shareholders totaling $90,000 for purchases of common stock at an 
      interest rate of 7.60%. At June 30, 1995, the Company had five notes 
      receivable outstanding from shareholders totaling $169,000 for 
      purchases of common stock at interest rates ranging from 5.47% to 
      7.60%. Full payment of principal and accrued interest on the notes is 
      due four years from the date of purchase of the common stock. 

(11)  DEVELOPMENT AND LICENSE AGREEMENTS

      The Company has a significant number of development and license 
      agreements.  Revenues earned from milestone and licensing fees under 
      development and license agreements were $1,670,000, $414,000 and 
      $1,817,000 for the years ended June 30, 1996, 1995 and 1994, 
      respectively. No royalty payments have been received by the Company. 
      Other partner revenues were earned for sales of reagents to customers.

      Development and license agreements which involve significant financial 
      commitments include the following:

      SUMITOMO PHARMACEUTICALS CO., LTD.

      In March 1993, the Company entered into a research and development 
      agreement with Sumitomo Pharmaceuticals Co., Ltd. (Sumitomo). Under the 
      terms of the agreement, the Company will update existing, and develop 
      new, diagnostic assay kits for the detection and management of bone and 
      other connective tissue diseases. The distribution and marketing rights 
      for these kits in Japan will be held by Sumitomo. Under certain 
      circumstances, Sumitomo will also have the right to acquire marketing 
      and distribution rights in certain Asian markets. Under the agreement, 
      the Company will also manufacture and supply the products at formula 
      prices which are subject to periodic renegotiation. The term of the 
      agreement is for an initial ten-year period with options to extend the 
      term upon mutual consent. Sumitomo has the right to terminate the 
      agreement upon six months written notice. Payments for certain ongoing 
      costs of research and development incurred by the Company are payable 
      to the Company under the agreement upon the achievement of certain 
      milestones and regulatory approvals.

      In June 1994 and February 1995, the Company entered into two additional 
      agreements with Sumitomo, granting Sumitomo certain additional 
      marketing and distribution rights. These agreements call for Sumitomo 
      to pay the Company certain amounts upon the achievement of certain 
      milestones and regulatory approvals.

      DIAGNOSTIC PRODUCTS CORPORATION

      In December 1993, the Company entered into a three-year agreement with 
      automatic one-year renewal periods unless terminated by either party 
      with Diagnostic Products Corporation (DPC) under which DPC received a 
      license to format the Company's assays for use on DPC's Immulite 
      automated testing systems. The agreement calls for DPC to manufacture 
      the licensed products and for the Company to purchase the licensed 
      products from DPC and sell and distribute them to users of Immulite 
      systems. Provided that DPC places a specific minimum number of Immulite 
      units worldwide, the Company is required to purchase a specific minimum 
      number of product kits from DPC during the first three years following 
      commercialization of the product. The Company's minimum purchase 
      commitments could equal $2,031,000 provided DPC achieves certain 
      milestones. The Company is also obligated to pay DPC a royalty on 
      future sales of the product kits.

      Norian Corporation, creating a new company, Orquest, Inc. Orquest 
      intends to commercialize novel collagen matrix technology to promote

(13)  INCOME TAXES

      As discussed in note 1, the Company adopted SFAS No. 109 effective as 
      of July 1, 1993 on a prospective basis. The cumulative effect of this 
      change in accounting for income taxes did not have a significant effect 
      on the consolidated financial statements. 

      Due to the operating losses incurred since inception, income tax 
      expense for all periods has consisted only of minimum state taxes.

      Income tax expense differed from the amounts computed by applying the 
      U.S. federal income tax rate of 34% of pretax losses as a result of the 
      following:

      The valuation allowance for deferred tax assets as of July 1, 1994 was 
      $4,683,000. The net change in the valuation allowance for the years 
      ended June 30, 1996 and 1995 was an increase of $4,355,000 and 
      $2,531,000, respectively. Management believes significant uncertainty 
      exists regarding the ability to realize the Company's deferred tax 
      assets and accordingly, a valuation allowance has been established. 
      When realized, approximately $231,000 of deferred tax assets will be 
      credited to paid-in-capital. 

      As of June 30, 1996, 1995 and 1994, the Company had federal tax net 
      operating loss carryforwards of approximately $27,193,000, $17,607,000 
      and $11,204,000, respectively, which expire in 2004 through 2010. The 
      Company also had foreign loss carryforwards of $806,000 at June 30, 
      1996 which extend indefinitely.

      The Company also has federal research credit carryforwards of 
      approximately $436,000, $436,000 and $314,000 at June 30, 1996, 1995 
      and 1994, respectively, which will expire in 2004 through 2010. 

      State tax net operating loss carryforwards were approximately 
      $13,206,000, $8,545,000 and $5,393,000 and research and development 
      credit carryforwards were $295,000, $250,046 and $174,000 at June 30, 
      1996, 1995 and 1994, respectively. The state losses expire in 1997 
      through 2001 and the credits expire in 2004 through 2011. 

      The Company's ability to utilize federal and state net operating loss 
      carryforwards and research credits is subject to annual limitations 
      under certain provisions of the Internal Revenue Code.

(16)  ACQUISITION OF OSTEO SCIENCES CORPORATION

      On January 31, 1996, the Company purchased Osteo Sciences Corporation 
      ("Osteo") in a tax free exchange which resulted in shareholders of 
      Osteo exchanging all of their shares of preferred and common stock for 
      shares of the Company's common stock. The Company issued 541,072 shares 
      of common stock to Osteo shareholders valued at approximately 
      $9,672,000 and assumed options to purchase 19,343 shares of the 
      Company's common stock valued at approximately $345,000. The 
      transaction was recorded using the purchase method of accounting and 
      resulted in the Company incurring a one-time charge of $11,291,000 for 
      acquired in-process research and development. The operations of Osteo 
      were included in the Company's results of operations beginning 
      February 1, 1996.

    The calculation includes the shares of mandatorily redeemable convertible 
preferred stock (Series A, Series B, Series C, Series D and Series E) and a 
convertible warrant as if they had converted to common stock on their 
respective original dates of issuance, because such shares automatically 
convert to common stock upon the closing of the initial public offering of 
the Company's common stock.
