Part I

Item 1. BUSINESS

General

Theragenics Corporation ("Theragenics" or the "Company") is a leader in the
production and sales of implantable radiation devices ("seeds") used in the
treatment of prostate cancer. The Company produces and sells TheraSeed(R); a
FDA-licensed device based on Pd-103, a radioactive isotope. Management believes
the Company is currently the only company commercially producing Pd-103 for use
in medical devices. In the treatment of prostate cancer, TheraSeeds(R) are
implanted ("seeding") into the prostate in a one-time, minimally invasive
procedure. The radiation emitted by the seeds is contained within the immediate
prostate area, killing the tumor while sparing surrounding organs. TheraSeed(R)
has been shown in independent clinical studies to offer success rates that are
comparable to or better than other conventional therapies, while being
associated with a reduced incidence of side effects. In addition, TheraSeed(R)
offers significant quality of life and cost advantages. Since 1987, TheraSeed(R)
has been used by physicians in over 400 centers across the United States. Sales
of TheraSeed(R) increased 58% in 1996 and 99% in 1997 due to increased and
reliable production from the Company's cyclotron-based manufacturing process and
higher demand for TheraSeed(R) as a result of increased marketing efforts and
the release of favorable clinical data. TheraSeed(R) has also been used on a
limited basis to treat cancers of the pancreas, lung, head, neck, oral cavity,
brain and eye.

On May 30, 1997, the Company entered into a sales and marketing agreement with
Indigo Medical, Inc., a subsidiary of Johnson & Johnson, granting Indigo the
exclusive worldwide right to market and sell TheraSeed(R) for the treatment of
prostate cancer. Management believes the alliance with Indigo will provide for
sales growth and international expansion while allowing the Company to focus its
resources on maintaining its leadership in the production of Pd-103 for prostate
cancer treatment and other potential applications. By leveraging the extensive
worldwide marketing capability of Indigo and Johnson & Johnson, the Company has
eliminated the need to develop an extensive, vertically integrated sales,
marketing, education and training network for the sale of TheraSeed(R) for
prostate cancer treatment.



Theragenics received FDA clearance to market TheraSeed(R) in 1986 and
commenced product sales in 1987. The Company has been profitable in every
quarter since 1991. In 1992, management increased its control over the
manufacture of TheraSeed(R) while maintaining quality and regulatory compliance
by integrating into the Company the production of Pd-103.

Industry Overview

Prostate Cancer

Excluding skin cancer, prostate cancer is the most common form of cancer,
and the second leading cause of cancer deaths, in men. Based on industry data,
the Company estimates that in 1995 the cost of treating prostate cancer exceeded
$3.0 billion in the United States. In 1998, the American Cancer Society
estimates there will be 184,500 new cases of prostate cancer and an estimated
39,200 deaths associated with the disease. Between 1989 and 1992, prostate
cancer incidence rates increased dramatically, probably due to the increasing
use of prostate-specific antigen (PSA) blood test screenings. In 1993 and 1994,
prostate cancer incidence rates declined as the initial impact of improved
diagnosis caught up with already existing but undiagnosed cases of prostate
cancer. Overall from 1973 to 1994, incidence rates for white men increased from
63 to 135 per 100,000 and incidence rates for African-American men increased
from 106 to 234 per 100,000.

Prostate cancer incidence and mortality increase with age; 77% of men
diagnosed with prostate cancer each year are over 65 years old. While rare in
young men, incidence rates accelerate with age. Illustratively, incidence rates
are 1 in 100,000 for men under 40, 82 in 100,000 for men ages 50-54, 518 in
100,000 for men ages 60-64, and 1,326 in 100,000 for men ages 70-74. Estimates
by the United States Bureau of Census indicate the number of men most prone to
prostate cancer, those 40 to 80 years old, will grow to 55 million by 2006 from
45 million in 1996. The Company estimates that in 1997, its U.S. market share in
the treatment of early stage localized prostate cancer was approximately 5%.

The prostate is a walnut-sized gland surrounding the male urethra, located
below the bladder and adjacent to the rectum. The two most prevalent prostate
diseases are benign prostatic hyperplasia ("BPH") and prostate cancer. BPH is a
non-cancerous enlargement of the innermost part of the prostate. Prostate cancer
is a malignant tumor that begins most often in the periphery of the gland and,
like other forms of cancer, may spread beyond the prostate to other parts of the



body. If left untreated, prostate cancer can metastasize to the lung or bone,
resulting in death. The following table summarizes the various stages of
prostate cancer.

Classification Stage of Progression
- - -------------- --------------------
A Clinically unsuspected
B Tumor confined to the prostate gland (localized)
C Tumor outside prostate capsule
D Metastasized into pelvic lymph nodes
D2 Metastasized into distant lymph nodes,
organs, soft tissues or bone

Approximately 58% of new prostate cancer diagnoses are defined as being
localized. Prostate cancer is typically curable when detected early, but the
lack of early-stage symptoms makes diagnosis difficult. Until 1988, the best
method of routine examination had been the digital rectal exam, an uncomfortable
subjective determination. In 1988, a diagnostic test was developed that
determines the amount of prostate specific antigen ("PSA") present in the blood.
PSA is found in a protein secreted by the prostate, and elevated levels of PSA
are associated with either prostatitis (a noncancerous inflammatory condition)
or a proliferation of cancer cells in the prostate. As stated earlier, the
number of new prostate cancers diagnosed increased significantly from 1989 to
1993 as a result of physicians' use of the PSA test. Industry studies have shown
that the PSA test can detect prostate cancer as many as five years earlier than
the digital rectal exam. The PSA test is currently part of the routine medical
check-up for prostate assessment. Transrectal ultrasound tests and biopsies are
typically performed on patients with elevated PSA readings to confirm the
existence of cancer.

Treatment Options

In addition to seeding, prostate cancer can be treated with radical
prostatectomy ("RP"), external beam radiation therapy ("EBRT"), hormone therapy,
chemotherapy and watchful waiting. Some of these therapies may be combined in
special cases to address a specific cancer stage or patient need. For example,
TheraSeed(R) has been used in combination with EBRT to treat some locally
advanced cases of prostate cancer. The treatments that have been most successful
are those that remove or kill all of the cancerous tissue while avoiding
excessive damage to the surrounding healthy tissue. When the cancerous tissue is
not completely eliminated, the cancer typically returns to the primary site,
often with metastases to other areas. The following is a summary of treatment
options for prostate cancer other than seeding.

Radical Prostatectomy is a major surgical procedure that involves the complete
removal of the prostate gland. This procedure has been used for over 30 years
and is considered to be the standard medical treatment for early-stage,
localized tumors. RP typically requires a three to seven day hospital stay and a
lengthy recovery period (generally four to six weeks). Side effects include
impotence and incontinence. The cost of RP ranges from $20,000 to $30,000 per
procedure, excluding treatment for side effects and postoperative complications.
Approximately 120,000 men underwent RP in 1995.

External Beam Radiation Therapy involves directing a beam of radiation at
the prostate gland to destroy tumorous tissue and has been a common technique
for treating many kinds of cancer since the 1950s. EBRT has typically been
reserved for early-stage prostate cancer in locally advanced cases where the
patient is an inappropriate surgical risk. The therapy consists of a series of
daily treatments usually lasting from six to eight weeks. Rectal complications
resulting from damage to the rectal wall caused by the radiation beam as it
travels to the prostate are the most common side effects. Principal side effects
also include incontinence and impotence, but these side effects generally occur
with less frequency than they do following RP. EBRT is estimated to cost between
$12,000 to $15,000 per patient. Approximately 35,000 men underwent EBRT in 1995.

Ancillary Therapies, primarily consisting of hormone therapy and
chemotherapy, are used to slow the growth of cancer and reduce tumor size, but
are generally not intended to be curative. Ancillary therapies are often used
during advanced stages of the disease to extend life and relieve symptoms. Side
effects of hormonal drug therapy include increased development of breasts,
impotence and decreased libido. In addition, many hormone pharmaceuticals
artificially lower PSA levels in patients, which can interfere with staging the
disease and monitoring its progress. Side effects of chemotherapy include
nausea, hair loss and fatigue. Drug therapy and chemotherapy require long-term,
repeated administration of medication on an outpatient basis.

Watchful Waiting is recommended by some physicians in certain circumstances
based on the severity and growth rate of the disease, as well as on the age and
life expectancy of the patient. The aim of watchful waiting is to monitor the
patient, treat some of the attendant symptoms and determine when more active
intervention is required. Watchful waiting has gained popularity among those



patients refusing treatment due to side effects associated with radical
prostatectomy. Watchful waiting requires periodic physician visits and PSA
monitoring.

In addition to the treatment options described above, other forms of
treatment as well as prevention are being developed and tested in clinical
settings.

The Theragenics Solution

Theragenics produces TheraSeed(R), an FDA-cleared device currently used
principally in seeding for the treatment of prostate cancer. In this
application, TheraSeeds(R) are implanted throughout the prostate gland in a
minimally invasive surgical technique under ultrasound guidance. The radiation
emitted by the seeds is contained within the immediate prostate area, killing
the tumor while sparing surrounding organs. The seeds, whose capsules are
biocompatible, are not removed after delivering their radiation dose to the
prostate. TheraSeed(R) is best suited for solid localized tumors and is
typically classified as a treatment for early-stage disease.

Management believes TheraSeed(R) offers significant advantages over RP and
EBRT. Recent multi-year clinical studies indicate that seeding offers success
rates that are comparable to or better than those of RP or EBRT plus reduced
complication rates. In addition, the TheraSeed(R) treatment is a one-time
outpatient procedure with a typical two to three day recovery period. By
comparison, RP is an inpatient procedure typically accompanied by a three to
seven day hospital stay and a four to six week recovery period, and EBRT
involves six to eight weeks of daily radiation treatments. Treatment with
TheraSeed(R) generally costs $10,000 to $15,000 per procedure, which is
substantially lower than the cost of RP and comparable to the cost of EBRT.

TheraSeed(R) is a radioactive "seed" approximately 4.5 millimeters long and
0.8 millimeters wide, or roughly the size of a grain of rice. Each seed consists
of a biocompatible titanium outer capsule containing the radioactive substance
Pd-103. The half-life of Pd-103, or the time required to reduce the emitted
radiation to one-half of its initial level, is 17 days. The half-life
characteristics result in the loss of almost all radioactivity in less than four
months.

Treatment Protocol

Prostate cancer patients electing seed therapy first undergo a transrectal
ultrasound test or CT scan, which generates a two-dimensional image of the



prostate. With the assistance of a computer program, a three dimensional
treatment plan is designed that calculates the number and placement of the seeds
required for the best possible distribution of radiation to the prostate.

Once the implant model has been constructed, the procedure is scheduled and
the seeds are ordered. The number of seeds implanted normally ranges from 40 to
100, with the number of seeds varying with the size of the prostate. The
procedure is usually performed under local anesthesia in an outpatient setting.
An ultrasound probe is first positioned in the rectum to guide needle placement
and seed location. Correct needle placement is facilitated by a template, or
grid, that covers the perineum (the area between the scrotum and rectum through
which the needles are inserted). This template is attached to the ultrasound
probe. Implant needles loaded with seeds are assigned to the appropriate
template holes as indicated in the treatment plan. Each needle is guided through
the template and then through the perineum to its predetermined position within
the prostate under direct ultrasound visualization. The seeds are implanted as
the needle is withdrawn from the prostate. When all seeds have been inserted,
the ultrasound image is again reviewed to verify seed placement.

An experienced practitioner typically performs the procedure in approximately
60 to 90 minutes, with the patient often returning home at day's end. Seeding
has been used as a treatment for prostate cancer since the early 1980s, when
seeds containing the radioactive isotope Iodine-125 ("I-125") were implanted in
prostate tumors under open surgery. However, this technique fell into disfavor
because the seeds were often haphazardly arranged resulting in radiation not
reaching all of the targeted cancerous prostate. Compounding this was that often
an unintended radiation dose was delivered to healthy surrounding tissues,
particularly the urethra and rectum. Clinical results indicate that the computer
modeling, advanced imaging and other techniques used in seeding today have
significantly ameliorated these drawbacks.

Clinical Results

Strong Efficacy Results. Clinical data indicates that seeding offers success
rates that are comparable to or better than those of RP or EBRT. In a study
published in Urology Times in September 1994, Drs. John Blasko and Haakon Ragde
of the Northwest Tumor Institute in Seattle, Washington, in a study of 298 men
with early-stage prostate cancer, found an actuarial local control rate of 96%
after treatment with either PD-103 or I-125 seed implantation. A study published
in 1995 by Drs. Blasko and Ragde found 100% of the 111 patients treated with
TheraSeed(R) for localized early-stage prostate cancer showed no localized
prostate cancer after treatment follow-up ranging from 12-73 months, with a
median follow-up of 32 months. The actuarial disease-free rate at 54 months was
89%. Updating their previous study on patients treated with Pd-103 or I-125 for
a paper published for the Seminars in Surgical Oncology 1997, Drs. Blasko,
-----------------------------
Ragde, Grimm, et al. found a seven-year actuarial local (confined to the
prostate) and distal (outside the prostate) disease-free rate of 97% and 95%,
respectively for 320 patients treated for localized early-stage prostate cancer.
They also presented therein an eight-year actuarial local and distal
disease-free rate of 91% and 83%, respectively for 231 patients who were
considered to represent higher risks of locally advanced prostate cancer and
were treated with a combination of Pd-103 or I-125 seeding and a modified dose
of EBRT. A study by Dr. Michael Dattoli of University Community Hospital, Tampa,
Florida and Dr. Kent Wallner of Memorial Sloan-Kettering Cancer Center, New
York, New York, published in the International Journal of Radiation Oncology,
Biology and Physics in July 1996 found a three-year actuarial freedom from
biochemical failure (based on PSA scores) of 79% among 73 patients with
clinically localized, high risk prostate cancer who were treated with EBRT in
combination with Pd-103. This compares favorably to results reported for
patients treated with conventional dose EBRT alone. These locally advanced cases
are significant because typical RP protocols would not classify them as suitable
for surgical treatment.

Reduced Incidence of Side Effects. Because TheraSeed(R) delivers a highly
concentrated and confined dose of radiation directly to the prostate, healthy
surrounding tissues and organs are spared excessive radiation exposure. This
results in significantly fewer and less severe side effects and complications
than are incurred with other conventional therapies. RP generally results in a
50-90% impotence rate and a 2-65% incontinence rate, and EBRT generally results
in impotence and incontinence rates of 40-60% and 10-25%, respectively. In
contrast, according to the 1995 study by the Northwest Tumor Institute described
above, it was reported that 85% of seed therapy patients under 70 years of age
who were potent before the procedure remained so. In addition, patients who had
not had a previous transurethral prostate resection ("TURP") suffered no
incontinence. Patients having a previous TURP have compromised urinary tracts
and can experience higher rates of incontinence. Patients receiving seeding can
expect some urinary urgency post-implantation as the Pd-103 delivers its
radiation dose.


Lower Treatment Cost. The total cost of seeding is approximately $10,000 to
$15,000 per procedure. This is approximately one-half the cost of RP, which
ranges from $20,000 to $30,000, excluding treatment for side effects and
post-operative complications. Seeding cost is comparable to the cost of EBRT,
which ranges from $12,000 to $15,000 for a six-to-eight week course of
treatment.

Management believes TheraSeed(R) represents the best available form of
seeding. Another radioactive isotope, Iodine-125 ("I-125"), is also commercially
available as a permanent implant. TheraSeed(R) is the first commercially
available alternative isotope to I-125 since I-125's introduction in the 1970s.
Management believes I-125 and Pd-103 are used with relatively equal frequency in
substantially all prostate cancer seeding procedures. Another technique known as
"temporary seeding," which involves the temporary placement of an Iridium-based
source in or near a tumor, is used in a very small percentage of cases.
Management believes Pd-103 has the following advantages over I-125: (i) Pd-103
delivers three times the initial dose rate of I-125, which can yield advantages
in treating aggressive cancers, (ii) Pd-103 has approximately one-third the
half-life of I-125, which shortens radiation induced side effects and exposure
to medical personnel in treatment follow-up; and (iii) unlike I-125, Pd-103 is
nontoxic and non-volatile as it decays. Management is not aware of any clinical
studies directly comparing the efficacy of Pd-103 versus I-125.

Strategy

In an effort to enhance market penetration and maintain technological
leadership, the Company has signed a sales and marketing agreement with Indigo
Medical, Inc., a Johnson & Johnson Company. Management believes that this
agreement will allow Theragenics and Indigo to take the seeding treatment of
prostate cancer to levels of penetration previously unseen by leveraging the
consumer marketing, health care organization network, training capacity and
international capabilities of Johnson & Johnson.

Production

The production of TheraSeed(R) is dependent upon the availability of Pd-103,
as well as Rhodium-103 ("Rh-103"), titanium, graphite and lead. With the
exception of Pd-103, all of these raw materials are relatively inexpensive and
readily available from third party suppliers.

Pd-103 is a radioactive isotope that can be produced by neutron bombardment
of Pd-102 in a nuclear reactor, or by proton bombardment of Rh-103 in a
cyclotron. Following the production of Pd-103 from Rh-103 in the cyclotron, the
Pd-103 is harvested from the cyclotron and moved through a number of proprietary
production processes until it reaches its final seed form.

To increase its control over timely, consistent and continuing availability,
quality and cost of Pd-103, the Company turned away from neutron bombardment of
Pd-102 and to the proton bombardment method of producing Pd-103. To accomplish
this alternative method of production, the Company contracted in 1992 for the
purchase of a cyclotron for in-house production of Pd-103. After the cyclotron
was delivered and reliable production of Pd-103 was proven, the Company
discontinued its reliance on outside vendors for irradiation services.

The Company has four cyclotrons in production and is currently installing a
fifth, which is scheduled to become operational during the second quarter of
1998. The Company has ordered nine additional cyclotrons, three to be installed
in fiscal 1998, and six in fiscal 1999. The Company's cyclotrons are designed,
built, installed and tested by a company specializing in the construction of
such equipment. A number of proprietary design modifications are incorporated in
the cyclotrons. These modifications are subject to confidentiality agreements
with the cyclotron manufacturer and the Company's own personnel.

Due to the highly sophisticated and technical nature of the equipment, the
Company has in the past encountered delays and difficulties in the construction,
installation and testing of its cyclotrons. Management cannot be certain that
such problems will not occur in connection with the construction, installation
and testing of the cyclotrons to be installed in 1998 and 1999.

Cyclotron operations constitute only one component of the TheraSeed(R)
manufacturing process. Because the production of TheraSeed(R) is highly
sensitive and labor intensive, management is focusing significant attention and
effort on automating and otherwise improving all aspects of the Company's
manufacturing process. Although the automation process is difficult and time
consuming, and has been subject to significant delays, management believes it
can improve efficiency, further reduce radiation exposure to personnel and
provide additional production capacity for TheraSeed(R).

During 1997, the Company received certification that its quality control
system meets all the requirements of the International Organization for
Standards' ISO 9001/EN46001 Quality System Standard. The Company is currently
working toward obtaining a CE mark. Receipt of a CE mark is a necessary step for
any future launch of Theraseed(R) in the European Community.

Marketing

Strategic Alliance. In 1997, the Company entered into a sales and marketing
agreement with Indigo Medical, Inc., a subsidiary of Johnson & Johnson, granting
to Indigo the exclusive worldwide right to market and sell Theraseed(R) for the
treatment of prostate cancer. Indigo has assumed responsibility for the
education and training of urologists, radiation oncologists and other personnel
involved in the use of TheraSeed(R) for the treatment of prostate cancer.

Management believes the alliance with Indigo will provide for sales growth and
international expansion while allowing the Company to focus its resources on
maintaining its leadership in the production of Pd-103 for prostate cancer
treatment and other potential applications. By leveraging the extensive
worldwide marketing capability of Indigo and Johnson & Johnson, the Company
eliminates the need to develop an extensive, vertically integrated sales,
marketing and education and training network for the marketing of Theraseed(R)
for prostate cancer.

Based on the current high level of demand in the prostate cancer market and
production capacity, management does not anticipate having the ability to
generate significant sales in other cancer areas in the coming year.

TheraSphere(R)

Theragenics has also participated in the development of TheraSphere(R), a
microscopic radioactive glass sphere designed for the treatment of liver cancer.
The Company holds a worldwide exclusive license from the University of Missouri
for the use of the technology required to produce TheraSphere(R). The Company
has granted to Nordion International, Inc. ("Nordion") an exclusive worldwide
sublicense to manufacture, distribute and sell TheraSphere(R) for any
application. TheraSphere(R) has been approved for distribution in Canada, but
has not been approved by the FDA for distribution in the United States. Under
the terms of the sublicense, Nordion has agreed to obtain the necessary
regulatory approvals for distribution of TheraSphere(R) in the United States and
other countries. The commercial development and regulatory approval of
TheraSphere(R) is still in its early stages, and management does not anticipate
significant revenues from TheraSphere(R) within the foreseeable future.

A TheraSphere(R) treatment dose contains approximately five million
yttrium-90 glass spheres that are each approximately half the diameter of a
human hair. The radiation dose is delivered to the tumor by introducing the
TheraSphere(R) by catheter into the hepatic artery, which carries arterial blood
to the liver. Because of greater blood flow to tumors compared to healthy liver
tissue, the microspheres concentrate in the capillaries feeding the tumor. The
concentration of microspheres in healthy tissue is much lower. Because of the
ability to place the radiation source in such close proximity to the tumor,
TheraSphere(R) can deliver a radiation dose to the tumor cells five times as
strong as that which can be delivered via external beam radiation.

Patents and Licenses; Trade Secrets

The Company holds United States patents directed to Pd-103 based on its
production using both cyclotrons and nuclear reactors. The Company also has
corresponding patents in Canada, South Africa, Japan and the 10 countries of the
European patent convention, and a PCT patent application on file for Japan,
Australia, New Zealand, Canada, and Europe (representing 16 European countries)
as well as a direct filing in Mexico. The Company may file additional patent
applications from time to time and considers the ownership of patents important,
but not necessarily essential, to its operations. The Company also uses a
strategy of confidentiality agreements and trade secret treatment to provide
primary protection to a number of proprietary design modifications in the
cyclotrons, as well as various production processes.

The Company also holds a worldwide exclusive license from the University of
Missouri for the use of technology required for producing TheraSphere(R).
Theragenics holds the rights to all improvements developed by the University of
Missouri on this technology. The Company, in turn, sublicenses exclusive
worldwide rights to this technology and all improvements to Nordion. Pursuant to
its license agreement with the University of Missouri, the Company is obligated
to pay the University the greater of a fixed annual amount or a percentage of
the gross sales amount derived from the sale of TheraSphere(R).

Theragenics holds patents for technology concerning methods for delivery of
TheraSphere(R) in several countries, including the United States, Canada,
Australia, Argentina, South Africa and the 10 countries of the European patent
convention, and has patent applications on file in other countries, including
Japan. The Company exclusively licenses this technology to Nordion for worldwide
use.

The Company relies to a significant degree on trade secrets, proprietary
know-how and technological advances that are either not patentable or which the
Company chooses not to patent. In particular, the Company has designed certain
modifications to its cyclotrons as well as various production processes that it
deems to be proprietary. The Company seeks to protect non-patented proprietary
information, in part, by confidentiality agreements with suppliers, employees
and consultants.

Competition

The Company competes in a market characterized by technological innovation,
extensive research efforts and significant competition. In general, TheraSeed(R)
competes with conventional methods of treating localized cancer such as RP and
EBRT. RP currently represents the standard medical treatment for early-stage,
localized prostate cancer. RP has a long history of favorable clinical results
and physicians have developed a high degree of familiarity and comfort with this
procedure. EBRT is also a well-established method of treatment and is widely
accepted for patients who do not represent a good surgical risk or whose
prostate cancer has advanced beyond the stage for which surgical treatment is
indicated. RP and EBRT are therefore well entrenched in the medical community
and in the universities and schools providing medical education. Management
believes that if general conversion from these established procedures to
TheraSeed(R) treatment does occur, such conversion will be the result of a
combination of equivalent or better efficacy, reduced incidence of side effects
and complications, lower cost, other quality of life issues and pressure by
health care providers and patients.

In addition, I-125 is commercially available as a permanent implant and
competes with TheraSeed(R). Management believes I-125 and Pd-103 are used with
relatively equal frequency in prostate cancer seeding procedures. I-125's dose
rate is approximately one-third that of Pd-103, however, and its half-life is
three times longer. Management believes Pd-103 enjoys a competitive advantage
over I-125 based on: (i) a higher dose rate, which can yield advantages in
treating aggressive cancers, (ii) a shorter half-life, which shortens radiation
induced side effects and exposure to medical personnel in treatment follow-up;
and (iii) Pd-103 is nontoxic and non-volatile as it decays. Management is aware
of no other similar radioactive products competing directly with TheraSeed(R). A
number of small companies have announced their intentions to produce I-125
and/or Pd-103 seeds for the treatment of prostate cancer. One such company, a
small start-up, consisting of certain former Theragenics' employees, has
indicated that they will have one cyclotron installed by the third quarter of
1998 for the purpose of producing Pd-103 for medical devices. Theragenics has
initiated legal action against the company for infringement of trade secrets and
the legal action is ongoing. To the best of Management's knowledge, Theragenics
is still the only company in the world currently producing quantities of Pd-103
for medical devices on a commercial basis.

Many companies, both public and private, are researching new and innovative
methods of preventing and treating cancer. In addition, many companies,
including many large, well-known pharmaceutical, medical device and chemical
companies, are engaged in radiological pharmaceutical and device research.
Significant developments by any of these companies could lessen or eliminate the
demand for the Company's products.







Government Regulation

The Company's present and intended future activities in the development,
manufacture and sale of cancer therapy products are subject to various laws,
regulations, regulatory approvals and guidelines. Within the United States, the
Company's therapeutic radiological devices must comply with the U.S. Federal
Food, Drug and Cosmetic Act, which is enforced by the FDA.

The Company is also required to adhere to applicable FDA regulations for
Good Manufacturing Practices, including extensive record keeping and reporting
and periodic inspections of manufacturing facilities.

The Company obtained FDA 510(k) clearance in 1986 to market TheraSeed(R)
for, in general, the treatment of localized solid tumors. A new 510(k) clearance
is required for any modifications in the device or its labeling that could
significantly affect the safety or effectiveness of the original product.

The Company's handling of radioactive materials is governed by the State of
Georgia in agreement with the NRC. The users of TheraSeed(R) are also required
to possess licenses issued either by the states in which they reside or the NRC
(depending upon which state is involved and the production process used). The
Company's expansion plans require the Company to secure additional permits and
licenses from a number of environmental, health and safety regulatory agencies.
The Company believes, but cannot assure, that it will be able to acquire the
permits and licenses necessary for its planned expansion of its manufacturing
capacity in accordance with the Company's timetable for its expansion. The
Company to date has not experienced delays in licensing any of its facilities or
cyclotrons.

The Company is required under its radioactive materials license to maintain
radiation control and radiation safety personnel, procedures, equipment and
processes, and to monitor its facilities and its employees and contractors. The
Company is also required to provide financial assurance that end-of-life
radiological decommissioning of its cyclotrons and other radioactive areas of
its property that contain radioactive materials will be adequately funded by the
Company. The Company's decommissioning obligations will increase as its
production capacity is expanded.

The Company disposes of low level radioactive waste to licensed commercial
radioactive waste treatment or disposal facilities for incineration or land
disposal. Management believes the Company is in compliance with all state and
federal regulations. The Company provides training and monitoring of its
personnel to facilitate the proper handling of all materials.

Employees

As of December 31, 1997, the Company had 111 full-time employees (including
full-time temporary employees and executive personnel). Of this total, 84 were
engaged in development and production of the Company's products. The remainder
were engaged in marketing and general corporate activities. The Company's
employees are not represented by a union or a collective bargaining unit, and
management considers employee relations to be good.

Item 2. Properties

The Company owns a 15,245 square-foot, single-story building in Buford,
Georgia, leases a 10,752 square-foot, single-story building in Norcross,
Georgia, and leases a 2,692 square-foot suite of offices in a four-story office
building in Norcross, Georgia. The larger Norcross facility houses the Company's
assembly, shipping, and administrative operations, the smaller Norcross facility
provides executive office space and the Buford facility houses the Company's
cyclotrons and its raw material processing operations. In 1996, the Company
purchased 30 acres of land adjacent to its Buford facility. Management is using
this land for long-term expansion of the Company's production facilities as
manufacturing expands to meet increasing sales demand. Currently under
construction on this land is a single story manufacturing facility of
approximately 80,000 square feet. Eventually all functions currently housed in
the leased Norcross facilities will be relocated to this new site adjacent to
its current Buford facility.

Item 3. Legal Proceedings

There are currently no material legal proceedings pending or, to the
knowledge of management, threatened against the Company.

Item 4. Submission of Matters to a Vote of Security Holders

The Company did not submit any matter to a vote of its security holders during
the fourth quarter of calendar 1997.








PART II

Item 5. Market for Registrant's Common Equity and Related
Stockholder Matters

The Company's Common Stock is traded on the Nasdaq National Market ("Nasdaq").
The trading symbol for the Company's Common Stock on Nasdaq is "THRX." The high
and low prices as reported on Nasdaq for the Company's Common Stock for each
quarterly period in 1996 and 1997 are as follows:

High Low
---- ---
1996
First Quarter............................................$12.25 $7.00
Second Quarter............................................18.63 8.63
Third Quarter.............................................19.25 11.75
Fourth Quarter............................................25.63 16.00

1997
First Quarter.............................................27.50 15.75
Second Quarter............................................25.38 15.05
Third Quarter.............................................50.00 22.25
Fourth Quarter............................................54.00. 33.00

As of March 16, 1998, the closing price of the Company's Common Stock was $69
per share. Also, as of that date, there were approximately 706 holders of record
of the Company's Common Stock. The number of record holders does not reflect the
number of beneficial owners of the Company's Common Stock for whom shares are
held by depositary trust companies, brokerage firms and others.

On February 14, 1997, the Company's Board of Directors adopted a Stockholder
Rights Plan (the "Rights Plan"). The Rights Plan contains provisions to protect
the Company's stockholders in the event of an unsolicited offer to acquire the
Company, including offers that do not treat all stockholders equally, the
acquisition in the open market of shares constituting control without offering
fair value to all stockholders and other coercive, unfair or inadequate takeover
bids and practices that could impair the ability of the Board of Directors to
represent stockholders' interests fully. Pursuant to the Rights Plan, the Board
of Directors declared and paid a dividend of one share purchase right (a
"Right") for each outstanding share of Common Stock held of record as of
February 28, 1997. The Rights, which will expire in February 2007, initially
will be represented by, and traded together with, the Common Stock. The Rights
are not currently exercisable and do not become exercisable unless certain
events occur, including the acquisition of, or commencement of a tender offer
for, 15% or more of the outstanding Common Stock. Each Right represents the
right to purchase from the Company one share of Common Stock at a purchase price
of $120.00, subject to adjustment. In the event certain triggering events occur,
including the acquisition of 20% or more of the outstanding Common Stock each
Right that is not held by the 20% or more stockholder will entitle its holder to
purchase additional shares of Common Stock having a market value of twice the
purchase price. As a result, the Rights Plan could add substantially to the cost
of acquiring the Company, and consequently could delay or prevent a change in
control of the Company. These effects could adversely affect the market price of
the Common Stock. Prior to the time the Rights become exercisable, the Board of
Directors may redeem the rights at a redemption price of $.01 per Right. The
description and terms of the Rights are set forth in a Rights Agreement dated as
of February 17, 1997 by and between the Company and SunTrust Bank, Atlanta, as
Rights Agent.

Dividend Policy

The Company has never declared or paid a cash dividend on its Common Stock. It
is the present policy of the Board of Directors to retain all earnings to
support operations and to finance expansion. Consequently, the Board of
Directors does not anticipate declaring or paying cash dividends on the Common
Stock in the foreseeable future. The Company's current credit facility restricts
the Company's ability to pay dividends if such dividend payment would cause a
default under any of the credit facility's financial covenants. Decisions on the
payment and amount of future dividends on the Common Stock will depend on the
Company's results of operations, capital requirements and financial condition
and other relevant factors as determined by the Board of Directors.

Stock Split

On March 16, 1998, the Company announced a two-for-one stock split to be
effected in the form of a 100% stock dividend payable on April 15, 1998 to
shareholders of record at the close of business on March 31, 1998.

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

Overview

Theragenics was founded in 1981 and is engaged in the manufacture and sale
of TheraSeed(R), a rice-sized device used for the treatment of localized
prostate cancer in a one-time, minimally invasive procedure. In 1986, the
Company received FDA clearance for its principal product, TheraSeed(R), for use
in any solid localized tumor. Sales increased 58% in 1996 and 99% in 1997 due to
increased and reliable production from the Company's cyclotrons and increased
demand for TheraSeed(R) as a result of growing market acceptance of this
treatment alternative for prostate cancer.

Production of Pd-103, the radioisotope supplying the therapeutic radiation
of TheraSeed(R), has always been a controlling factor in the Company's efforts
to generate sales. To increase its control over the timely and consistent
availability, quality and cost of Pd-103, the Company converted from reactor
produced Pd-103 to an alternative means of producing Pd-103 using a cyclotron.
In 1992, the Company contracted for the purchase of a cyclotron for in-house
production of Pd-103. After the cyclotron was delivered and reliable production
of Pd-103 was demonstrated, the Company discontinued its reliance on outside
vendors for irradiation services.

In view of the scale of the investment necessary to add cyclotrons, the time
and effort required to develop the production process, and the Company's limited
access to debt and equity capital, the Company undertook a slow and measured
roll-out of its TheraSeed(R) product. Management focused primarily on the
careful development of relationships with the physician community and on
ensuring that the Company's production capabilities could meet demand for its
product. The Company added additional cyclotrons in 1995, 1996, and 1997 for a
total of four cyclotrons. Four additional cyclotrons are scheduled to become
operational in 1998 and six in 1999. Because a cyclotron does not become
available for production until approximately 18 months after it is ordered, the
accuracy of the Company's long-term plans can significantly affect its results
of operations. The delivery of cyclotrons prior to a commensurate increase in
demand could adversely impact margins, while inadequate cyclotron capacity could
limit the Company's ability to meet demand and achieve maximum sales growth.

The Company is well underway on a $28 million capital expansion project that
includes the purchase of four additional cyclotrons and the construction of a
new production facility. Although no assurances can be given, management expects
that one new cyclotron will become operational in April, 1998, or shortly
thereafter and the next three becoming operational at three month intervals.
Contracts were signed for six additional cyclotrons to be delivered in 1999.
Again, while no assurances can be given, Management expects one to be
operational at the end of the first quarter 1999, three additional by the end of
third quarter 1999, and two more by the end of the fourth quarter of 1999, or
shortly thereafter. Each of these cyclotrons, including the facility to house
each, are estimated to cost less than $5,000,000.

On May 30,1997, the Company entered into a sales and marketing agreement
with Indigo Medical, Inc., a subsidiary of Johnson & Johnson, granting the
exclusive worldwide right to market and sell Theraseed(R) for the treatment of
prostate cancer. Under the terms of the agreements, Indigo has assumed
responsibility for the education and training of urologists, radiation
oncologists and other personnel involved in the use of TheraSeed(R) as well as
all other sales and marketing activities. The Company continues to be
responsible for all manufacturing and distribution for TheraSeed(R).


Results of Operations

Year Ended December 31, 1997 Compared to Year Ended
December 31, 1996

Product sales were $24.6 million in 1997 compared to $12.4 million in 1996,
an increase of $12.2 million, or 98.4%. Market acceptance of the Company's
TheraSeed(R) treatment alternative for prostate cancer grew during 1997.
Concurrently, the Company was able to reliably increase production from its
cyclotron-based manufacturing and thereby take advantage of increased demand.
Sales also reflect that the Company had four cyclotrons available during much of
1997 to meet sales demand as compared to only two cyclotrons throughout 1996.

Licensing fees represent royalty payments with respect to the Company's
licensed TheraSphere(R) technology. Management does not expect licensing fees to
become material in the foreseeable future. See Note F of Notes to Financial
Statements.

Cost of product sales was $6.1 million in 1997 compared to $3.7 million in
1996, an increase of $2.4 million, or 64.9%. This increase was due primarily to
incremental staffing and cyclotron related costs. Staffing increases were
necessary to respond to and anticipate sales growth. Cyclotron operating costs
and depreciation increased as all four of the Company's cyclotrons were in
service by February, 1997. As cyclotrons come on-line, margins decline because
each machine represents excess capacity for a period while carrying its full
component of fixed costs, including depreciation. As a percentage of product
sales, cost of product sales decreased from 30.5% in 1996 to 25.0% in 1997. This
decrease resulted from economies of scale.

Selling, general and administrative expense was $4.8 million in 1997
compared to $3.2 million in 1996, an increase of $1.6 million, or 50.6%. Primary
contributors to this increase were legal and professional fees and compensation
and related expense. Legal and professional expense fees increased as the
Company completed the Theragenics/Indigo Sales and Marketing Agreement and
initiated legal action against a small company founded by former employees.
Compensation and related expenses rose as the number of employees increased and
salaries were increased reflecting the larger scope of the Company's operations
and the need to attract and retain qualified employees. There were also higher
expenditures in a number of areas representing support for higher sales levels.
Despite these increases, selling, general and administrative expense as a
percentage of net sales decreased from 26.1% in 1996 to 19.7% in 1997 due to
economies of scale.

During the periods presented, the Company had no ongoing pure research
function. As in the past, much of the development component of research and
development of product and processes is incorporated in the manufacturing area
and therefore is included in the cost of goods sold category. Management may
choose to develop a more traditional research and development program if and
when appropriate opportunities are identified and resources are in place.

Other income (expense) during the periods presented consist principally of
interest income, interest expense and the write-off of unamortized loan costs as
a result of loan refinancing. Interest income jumped dramatically, reflecting
interest on funds received as a result of the secondary stock offering completed
in April, 1997. Since these funds will largely be used to fund the Company's
expansion program in 1998 and 1999, management expects other income to return to
levels consistent with historical amounts.

The Company's effective income tax rate was approximately 38% in 1996 and
approximately 36% in 1997.


Liquidity and Capital Resources

During 1995, 1996 and 1997, the Company's principal cash needs related to
capital spending to increase manufacturing capacity. To manufacture
TheraSeed(R), the Company purchases, installs and operates cyclotrons, which
involves significant capital investment. The Company has funded its capacity
expansions in 1995 and 1996, principally from cash flows from operations and
bank borrowings, and in 1997 from cash flows from operations and the proceeds
from the secondary offering of common stock completed in April, 1997.

The Company had cash and short-term investments of $30.2 million at December
31, 1997, compared to $3.0 million at December 31, 1996. Working capital was
$39.0 million at December 31, 1997, This compares to $1.3 million at year end
1996, which included $3.5 million representing the current portion of long-term
obligations.

Cash provided by operating activities was, $5.7 million and $14.2 million
during 1996 and 1997, respectively. These amounts primarily represent net income
supplemented in 1997 by an increase in income tax payable and trade accounts
payable, and in all years by the tax sheltering effects of depreciation and
deferred tax expense. Offsetting these items were increases in accounts
receivable.

Cash used in investing activities was $8.6 million and $21.2 million in 1996
and 1997, respectively, consisting in each of these years primarily of purchases
of property and equipment. Spending in 1996 represents the continuation of a
project to add cyclotrons three and four to the facility, the purchase of 30
acres of land for the Company's expansion project and spending on an assembly
automation project. Spending in 1997 primarily represents the beginning of a
project to add four cyclotrons and a new manufacturing facility having an
estimated total cost of approximately $28 million. As of December 31, 1997,
approximately $11 million had been spent on this expansion project and less than
$2 million on other capital projects. Theragenics invested in marketable
securities and held $8.4 million of those securities at December 31, 1997 as
disclosed in Note B-3 in the Notes to Financial Statements attached hereto.

On January 23, 1998, the Company entered into six agreements, each for the
purchase of one additional cyclotron. Each cyclotron, including the facility to
house it, is expected to cost less than $5 million. The Company has made
payments to date on these six cyclotrons totaling approximately $5.5 million as
of March 16, 1998.

Cash provided (used) by financing activities was $(21,000), $2.6 million and
$34.2 million in 1995, 1996 and 1997, respectively. Cash flows from financing
activities relates principally to bank borrowings and repayments thereof,
proceeds from the exercise of stock options and warrants, and in 1997, proceeds
from the secondary placement of common stock, and common stock sold to Indigo
Medical as part of a sales and marketing agreement.

Management intends to continue its efforts toward increasing its Pd-103
production capacity. As such, over the next two fiscal years, the Company
intends to construct facilities, purchase cyclotrons, purchase other production
equipment, invest in research and development, invest in automation, and provide
for working capital and general corporate needs.

Management believes that current cash balances, cash from future operations
and its credit facility, will be sufficient to meet its working capital and
capital expenditure requirements for at least the next 12 months. In the event
additional financing becomes necessary, management may choose to raise those
funds through other methods of financing as appropriate.

YEAR 2000 ISSUE: Some computer systems used today were designed and developed
using two digits, rather than four, to specify the year. Consequently, such
systems may recognize a date of "00" as the year 1900 instead of year 2000. This
may cause many computer systems to fail or create inaccurate results unless
corrective measures are taken. We are currently implementing, or we have plans
to implement, upgrades to computer systems to properly recognize dates after
December 31, 1999. The financial impact associated with upgrades to systems to
address the year 2000 issue is not expected to have a material effect on the
Company's financial position or results of operations in any given year.

This document contains certain forward-looking statements within the meaning
of the private securities litigation reform act of 1995 including, without
limitation, statements regarding possible benefits associated with the alliance
with Indigo Medical Inc., future costs of sales, S, G & A expenses, research and
development, costs and timetable for capacity expansion and the sufficiency of
the Company's liquidity and capital resources. From time to time, the Company
may make other forward-looking statements relating to such matters as well as
anticipated financial performance, business prospects, technological
developments, research and development activities and similar matters. These
forward-looking statements are subject to certain risks, uncertainties and other
factors which could cause actual results to differ materially from those
anticipated, including risks associated with the management of growth,
government regulation of the therapeutic radiological, pharmaceutical and device
business, dependence on health care professionals, competition from conventional
and newly developed methods of treating localized cancer, and dependence on a
third party cyclotron manufacturer.

which have been experienced in the United States in recent years have had a
significant effect on the Company's net sales or profitability.

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

Board of Directors
Theragenics Corporation

We have audited the balance sheets of Theragenics Corporation (a
Delaware corporation) as of December 31, 1996 and 1997, and the related
statements of earnings, shareholders' equity, and cash flows for each of the
three years in the period ended December 31, 1997. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

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

In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Theragenics
Corporation as of December 31, 1996 and 1997, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,
1997, in conformity with generally accepted accounting principles.

Theragenics Corporation

NOTES TO FINANCIAL STATEMENTS

December 31, 1996 and 1997



NOTE A - ORGANIZATION AND DESCRIPTION OF BUSINESS

Theragenics Corporation (the "Company") was organized in November 1981 to
develop, manufacture, and market radiological pharmaceuticals and devices
used in the treatment of cancer. The Company manufactures and markets
primarily one product, TheraSeed(R), which is used primarily in the treatment
of prostate cancer. Use of the Company's product is regulated by the U.S.
Food and Drug Administration (FDA). Under a marketing and sales agreement
executed with Indigo Medical, Inc. (Indigo) in May 1997, (see Note F) all
TheraSeed(R) products used in the treatment of prostate cancer are sold to
Indigo. The TheraSeed(R) product is utilized by hospitals, physicians and
other health service providers in the United States. The Company therefore is
directly affected by changes in technology, as it may apply to cancer
treatment, and by FDA regulations and the well being of the health care
industry.

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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

1.Use of Estimates

In preparing financial statements in conformity with generally accepted
accounting principles ("GAAP"), management is required to make certain
estimates and assumptions that affect the reported amounts of assets and
liabilities and the disclosure of contingent assets and liabilities at the
date of the financial statements and revenues and expenses during the
reporting period. Actual results could differ from those estimates.

2.Cash and Short-Term Investments

For purposes of reporting cash flows, cash and short-term investments include
cash on hand, cash in banks and variable rate demand notes with original
maturities of less than 90 days.

3.Marketable Securities

Marketable securities are classified as available for sale and are reported
at fair value. Fair value is based upon quoted market prices. At December 31,
1997, marketable securities consisted of municipal and hospital authority
obligations. Marketable securities of $6,891,807 mature within one year and
marketable securities of $1,500,000 mature in 2004 with a put option
exercisable in 1998. At December 31, 1997, the fair value of marketable
securities approximated amortized cost. No marketable securities were held at
December 31, 1996.

NOTES TO FINANCIAL STATEMENTS - CONTINUED

December 31, 1996 and 1997


NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued

4.Inventories

Inventories are stated at the lower of cost or market. Cost is determined
using the specific identification method which approximates the first-in,
first-out (FIFO) method. Inventories consist primarily of work in process.

5.Property, Equipment, Depreciation and Amortization

Property and equipment are recorded at historical cost. Depreciation is
provided for in amounts sufficient to relate the cost of depreciable assets
to operations over their estimated services lives on a straight-line basis.
Depreciation and amortization expense related to property and equipment
charged to operations was approximately $810,000, $1,044,000 and $1,458,000
for 1995, 1996 and 1997, respectively. Estimated services lives are as
follows:

Building and improvements 30 years
Machinery, leasehold improvements,
furniture and equipment 5-10 years

A significant portion of the Company's depreciable assets are utilized in the
production of its product. Management periodically evaluates the
realizability of its depreciable assets in light of its current industry
environment. Management believes that no impairment of depreciable assets
exists at December 31, 1997. It is possible, however, that management's
estimates concerning the realizability of the Company's depreciable assets
could change in the near term due to changes in the technological and
regulatory environment.

The primary machinery and equipment utilized in the Company's manufacturing
process has been acquired from one vendor. Currently, the Company has
contracts for additional manufacturing equipment with this vendor. Management
believes that the vendor has the ability to continue to deliver the equipment
in accordance with the terms of the contracts. Any inability of the vendor to
meet its obligations for delivery of the equipment could have an adverse
affect on the Company's ability to increase its production capacity.

6.Patent Costs

The Company capitalizes the costs of patent applications for its products.
Amortization is computed on a straight line basis over the estimated economic
lives of the patents, commencing at the date of grant of the related patent.
Patent costs are net of accumulated amortization of $47,295 and $56,144 at
December 31, 1996 and 1997, respectively. Amortization related to patent
costs charged to operations was approximately $8,000, $10,000 and $9,000 for

7.Income Taxes

The Company accounts for income taxes using the asset and liability method.
Under this method, 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. Deferred tax assets and liabilities are measured using
enacted tax rates applied to taxable income. 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. A valuation allowance is
provided for deferred tax assets when it is more likely than not that the
asset will not be realized.

8.Research and Development Costs

The costs of research and development and consumable supplies and materials
to be used for the development of the Company's intended products are
expensed when incurred.

9.Advertising

The Company expenses the cost of advertising as incurred. Advertising expense
for the years ended December 31, 1995, 1996 and 1997 was approximately
$139,000, $229,000 and $230,000, respectively.

10. Earnings Per Share

The Company adopted Statement of Financial Accounting Standards No. 128 (SFAS
128), Earnings Per Share, in the fourth quarter of 1997. Basic net earnings
per common share is based upon the weighted average number of common shares
outstanding during the period. Diluted net earnings per common share is based
upon the weighted average number of common shares outstanding plus dilutive
potential common shares, including options and warrants outstanding during
the period. All comparative earnings per share data for prior periods
presented has been restated.

11. Stock Based Compensation

The Company's stock option plans are accounted for under the intrinsic value
method in which compensation expense is recognized for the amount, if any,
that the fair value of the underlying common stock exceeds the exercise price
at the date of grant.

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued

12. Fair Value of Financial Instruments

The Company's financial instruments include cash, cash equivalents,
marketable securities and long-term debt. The carrying value of cash and cash
equivalents approximates fair value due to the relatively short period to
maturity of the instruments. Marketable securities are classified as
available for sale and are reported at fair value. The carrying value of the
Company's long-term obligations approximates fair value based upon borrowing
rates currently available to the Company for borrowings with comparable
maturities.

13. Hedging Activities

The Company enters into foreign exchange forward contracts to hedge the price
risks associated with equipment purchase commitments denominated in foreign
currencies. The forward contracts typically mature concurrently with payments
required under the equipment purchase contracts. The Company does not hold
foreign exchange forward contracts for trading or speculative purposes. Gains
and losses are deferred and accounted for as part of the underlying
transactions. At December 31, 1997, foreign exchange forward contracts were
not significant.


NOTE C - CONSTRUCTION IN PROGRESS

Construction in progress consists primarily of payments made for construction of
manufacturing equipment and facilities expansion. Total cost of this project is
expected to be approximately $54,000,000 and is expected to be completed in
various stages through 1999. Total outstanding commitments of this project at
December 31, 1997 are approximately $40,000,000. Construction of equipment and
facilities totaling approximately $4,900,000 and $3,000,000 were completed and

substantially all of the Company's assets. Provisions of the loan agreement
limit the incurrence of additional debt and require the maintenance of
certain minimum financial ratios, among other things. As of December 31,
1997, the Company was in compliance with the provisions of the loan
agreement.

NOTE G - STOCK OPTIONS AND WARRANTS - Continued

The Company follows the practice of recording amounts received upon the
exercise of certain options by crediting common stock and additional paid-in
capital. No charges are reflected in the statements of operations as a result
of the grant or exercise of options. The Company realizes an income tax
benefit from the exercise or early disposition of certain stock options. This
benefit results in a reduction to income taxes payable and an increase in
additional paid-in capital.

The Company uses the intrinsic value method in accounting for its stock
option plans. In applying this method, no compensation cost has been
recognized. Had compensation cost for the Company's stock option plans been
determined based on the fair value at the grant dates for awards under those
plans, the Company's net earnings and earnings per share would have resulted
in the pro forma amounts indicated below:





1995 1996 1997
----------- ----------- -----------

Net earnings As reported $ 1,772,325 $ 3,384,506 $ 9,497,531
Pro forma 1,750,736 3,015,123 8,628,538

Basic net earnings per
common share As reported $ .16 $ .29 $ .69
Pro forma .16 .26 $ .63

Diluted net earnings per
common share As reported $ .15 $ .28 $ .66
Pro forma .15 .24 $ .61


For purposes of the pro forma amounts above, the fair value of each option
grant was estimated on the date of grant using the Black-Scholes
options-pricing model with the following weighted-average assumptions used
for grants in 1995, 1996 and 1997, respectively; expected volatility of 70%,
70% and 68%, risk-free interest rates of 5.86%, 6.33% and 5.87%; and expected
lives of 5.5 years, 7 years and 3.7 years.

Warrants

40,000 warrants were exercised during 1996 and 20,000 warrants were exercised
during 1997, resulting in proceeds to the Company of $300,000 and $150,000,
respectively. At December 31, 1997, there are outstanding warrants covering
40,000 shares of common stock. The warrants are exercisable at a price of
$7.50 per share and expire in May 1999.

details about comprehensive income that arise during a reporting period.
Comprehensive income includes revenue, expenses, gains and losses that bypass
the income statement and are reported directly in a separate component of
equity.

SFAS 131, Disclosure about Segments of An Enterprise and Related Information,
which is effective for fiscal years beginning after December 15, 1997. SFAS
131 requires companies to report information about an entity's different

it operates, referred to as operating segments.

Management does not expect the adoption of these new standards to have a
material impact on the Company's results of operations or financial
condition.

give Lender written notice (or telephonic notice promptly confirmed in
writing) substantially in the form of Exhibit C attached hereto, signed

the second Business Day prior to any Interest Period designated by
Borrower in such notice, direct that interest accrue on the unpaid
principal balance of the Revolving Credit Loans (or any portion thereof
which is in an amount of not less than $250,000 or any greater integral
multiple thereof) outstanding from time to time during such Interest
Period at a rate per annum equal to the sum of the Adjusted LIBOR for
such Interest Period plus the Applicable Interest Rate Margin in effect
from time to time and as more fully set forth in Section 2.4(D) below;
and provided, further, that (i) upon the occurrence and during the
continuation of any Event of Default, Lender may, upon notice to
Borrower, suspend Borrower's right to use the aforesaid Adjusted LIBOR

such designation by Borrower of an interest rate for the Revolving
Credit Loans based on the Adjusted LIBOR and of an Interest Period
applicable thereto shall be irrevocable and shall remain in effect
throughout such Interest Period. Upon determining any interest rate
based on the Adjusted LIBOR for an Interest Period requested by
Borrower, Lender shall notify the Borrower by telephone (which may be
confirmed in writing by Lender) of such determination, and such
determination shall, in the absence of manifest error, be final,
conclusive and binding for all purposes.

selecting a new Interest Period therefor, to commence on the last day
of the immediately preceding Interest Period, or (B) subject to the
availability of interest rates as provided in Sections 2.4(B) and
2.4(D) hereof, to convert all or any part of a Loan of one type into a
Loan of another type; provided, however, that Lender shall not be
