     The Board of Directors has fixed the close of business on April 17, 1998,
as the record date for the determination of stockholders entitled to receive
notice of, and to vote at, the forthcoming Annual Meeting of Stockholders or any
adjournment thereof. Any person giving a proxy in the form accompanying this

or by written notice to the Secretary of the Company received at the Company's
offices at 5325 Oakbrook Parkway, Norcross, Georgia, 30093 prior to the date of

represented thereby will be voted as directed in the executed proxy. If the
Proxy is signed and returned but no choice is specified therein, it will be
voted FOR the election of the nominees named therein and FOR each of the listed
proposals.
 
     The expenses for soliciting proxies for the forthcoming Annual Meeting of

by means of personal calls upon, or telephonic or telegraphic communications
with, stockholders or their personal representatives by directors, officers and
employees of the Company, who will not be specially compensated for such
services. The Company may or may not engage a proxy service to assist the
Company in the solicitation of proxies. The Company will reimburse brokers and
other nominees for their reasonable expenses incurred in forwarding soliciting
material to beneficial owners. It is anticipated that this Proxy Statement and
enclosed Proxy will first be mailed to stockholders entitled to notice of and to
vote at the Annual Meeting on or about April 30, 1998.

                              PROPOSAL NUMBER ONE
 
                             ELECTION OF DIRECTORS
 
     The Board of Directors of the Company is divided into three classes (Class
I, Class II and Class III) with two directors in each class. One class of
directors is elected each year for a three-year term. Two directors,
representing the Class III Directors, are to be elected at the Annual Meeting.
These Class III Directors will serve until the Annual Meeting of Stockholders in
2001 or until their successors shall have been elected and qualified. The
current Board of Directors has selected, and will cause to be nominated at the
meeting, Dr. Orwin Carter and Ms. M. Christine Jacobs, who upon election will
comprise the Class III Directors of the Board of Directors.
 
     Provided that a quorum of stockholders is present at the meeting in person
or by proxy, directors will be elected by a plurality of the votes cast at the
meeting. Abstentions and "broker non-votes" will have no effect on the election
of directors. The persons named on the enclosed proxy card or their substitutes
will vote all of the shares that they represent for the above-named nominees
unless instructed otherwise on the proxy card. If at the time of the Annual
Meeting of Stockholders any nominee is unable or declines to serve, the
discretionary authority provided in the proxy will be exercised to vote for a
substitute. Management has no reason to believe that a substitute nominee will
be required.
 
     THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE ELECTION OF THE NOMINEES
NAMED IN THIS PROPOSAL.
 
     The directors and director nominees have supplied the Company with the
following information concerning their age, principal employment, other
directorships and positions with the Company:

     Board Compensation Committee Report on Executive Compensation.  The

Officer. Compensation of other executive officers is set by the Chief Executive
Officer based on a structure similar to that established by the Compensation
Committee for compensation of the Chief Executive Officer, except that stock
options are awarded by the Stock Option

Committee of the Board of Directors. The Compensation Committee has a policy
that a significant portion of the Chief Executive Officer's pay should be
related to the performance of the Company and the Chief Executive Officer's
contribution to that performance. In determining the amount and type of
compensation, the Committee's goal is to provide a package that is competitive
with the marketplace while placing a substantial portion of the C.E.O.'s
compensation "at risk" by tying it to both short-term and long-term measures of
the Company's performance.
 
     During 1997, the Committee established criteria for the C.E.O.'s
performance bonus based upon a combination of dollar sales levels and dollar
after-tax profitability. A matrix (the "Matrix") was established, with cells
within the Matrix representing specific combinations of sales and profits.
Performance falling within a particular cell would result in a bonus to the
C.E.O. expressed as a percent of the C.E.O.'s base salary. This Matrix, which
allowed for bonuses running from 0% to 137% of the C.E.O.'s base salary, was
constructed to reward the C.E.O. for reaching specific combinations of sales and
profit levels with higher sales and profit resulting in a larger bonus. The
percentages within the Matrix recognize both the benefit to the Company of
reaching certain sales and profit levels and to a lesser extent the Committee's
assessment of the compensation the C.E.O. could obtain in the market. In
addition to the bonus called for in the Matrix, the Committee also has the
option of awarding the C.E.O. an additional bonus of up to 10% of her base
salary. This bonus, which is subjectively determined by the Committee, is based
on less quantifiable measures of performance (i.e., problem resolution, program
development and execution, internal processes and procedures development, cash
management and expense control, and the effective and efficient application of
available resources to ensure both short-term and long-term Company health).
 
     Based upon the above criteria applied to an almost 100% increase in sales
and an approximately 180% increase in profit, Ms. Jacobs was awarded a 147%
bonus or $294,000. The 147% bonus represents a 137% bonus called for by the
Matrix plus a 10% bonus for the less quantifiable measures of performance.
 
     It is also the Committee's responsibility to address issues raised by
Section 162(m) of the Internal Revenue Code. The revisions to this section made
certain non-performance-based compensation in excess of $1,000,000 to executives
of public companies nondeductible to the companies beginning in 1994. The
Committee has reviewed these issues and has determined that no portion of
compensation payable to any executive officer for 1997 is nondeductible.

     The Stock Option Committee of the Board of Directors administers the
Company's stock option plans and determines the terms of options granted under
these plans. These plans form the basis of the Company's long-term incentive
compensation plan. The Stock Option Committee believes that placing a portion of
executives' compensation in the form of stock options achieves three objectives.
It aligns the interest of the Company's executives directly with those of the
Company's stockholder's, gives executives a significant long-term interest in
the Company's success and helps the Company retain key executives. In
determining the number and terms of options to grant an executive, the Stock
Option Committee primarily considers the executive's past performance as an
indicator of future performance and the degree to which an incentive for
long-term performance would benefit the Company. Based on these factors, in
relatively equal proportions, the Stock Option Committee awarded the Chief
Executive Officer 240,000 options (adjusted for April 15, 1998, 2-for-1 stock
split) during fiscal 1996. No stock options were awarded to the C.E.O. in fiscal
1997. Mr. Smith was awarded the options shown in the table headed "Option Grants
in Fiscal 1997" while another 405,000 options (adjusted for April 15, 1998,
2-for-1 stock split) were granted to twelve other employees during fiscal 1997.

                    CORPORATION EMPLOYEE STOCK PURCHASE PLAN
 
INTRODUCTION
 
     The Board of Directors of the Company has adopted the Theragenics
Corporation Employee Stock Purchase Plan and has authorized the issuance of up
to 200,000 shares of Common Stock thereunder. The Employee Stock Purchase Plan
is intended to qualify as an "employee stock purchase plan" within the meaning
of Section 423 of the Internal Revenue Code of 1986, as amended (the "Code").
Stockholder approval of the Employee Stock Purchase Plan by a majority of the
votes cast is required under the Code. Abstentions and "broker non-votes" will
have no effect on Proposal Two.

PURPOSE
 
     The purpose of the Employee Stock Purchase Plan is to provide employees of
the Company with an opportunity to be compensated through the benefits of stock
ownership and to acquire an interest in the Company through the purchase of
Common Stock. The Employee Stock Purchase Plan enables eligible employees of the
Company to purchase Common Stock on advantageous terms and thereby allows such
employees to share in the success of the Company.
 
ELIGIBILITY
 
     Generally, any employee who was employed by the Company for at least one
year preceding the beginning date of each applicable calendar quarter, works
more than 20 hours per week, and is customarily employed for more than five
months during the calendar year shall be eligible to participate in the Employee
Stock Purchase Plan for the ensuing calendar quarter, except for certain
employees who are deemed to own more than 5% of the Common Stock of the Company.
Eligible employees desiring to participate in the Employee Stock Purchase Plan
must elect to do so prior to the commencement of each calendar year. Under the
terms of the Employee Stock Purchase Plan, no employee may be granted an option
that permits that employee to purchase shares of Common Stock under the Employee
Stock Purchase Plan and any other Section 423 plans of the Company or an
affiliate at a rate that exceeds $25,000 of the fair market value of the Common
Stock (determined at the time the option is granted) for each calendar year for
which the option is outstanding at any time.
 
MANNER OF STOCK PURCHASES
 
     The Employee Stock Purchase Plan operates on a calendar quarter basis. An
eligible employee who elects to participate in the Employee Stock Purchase Plan
will have payroll deductions made on each payday during a calendar quarter. The
amount of the payroll deductions shall be at least 1% and shall not exceed 10%
of the employee's compensation. A participant may withdraw payroll deductions
credited to his account under the Employee Stock Purchase Plan at any time
during a calendar quarter by giving written notice to the Company. In the event
a participant withdraws from the Employee Stock Purchase Plan for any reason,
all payroll deductions credited to his account will be paid to him or his
estate, and no further deductions will be made from the participant's pay. If a
participant ceases to be an employee of the Company for any reason, including
retirement or death, the participant will be deemed to have withdrawn from the
Employee Stock Purchase Plan on the date of his termination of employment. A
participant may not alter the rate of his payroll deductions during a calendar
quarter, except to stop payroll deductions, and any such request to stop payroll
deductions will be effective as of the first payroll period following the date
of the processing of such request.
 
     At the end of each calendar quarter, participant contributions will be used
to purchase for the participant a number of shares of Common Stock, subject to
adjustment, in an amount equal to 85% of the lower of the fair market value of
the Common Stock on the first day of such calendar quarter or the last day of
such calendar quarter. Any payroll deductions credited to a participant's
account during a calendar quarter not used for the purchase of shares will be
credited to the participant's payroll deductions for the next calendar quarter.
The closing price of the Common Stock on the Nasdaq National Market on April 16,
1998, was $29.75 per share.
 
FEDERAL INCOME TAX CONSEQUENCES OF THE EMPLOYEE STOCK PURCHASE PLAN
 
     The federal income tax consequences to the Company and the participants in
connection with the Employee Stock Purchase Plan under existing applicable
provisions of the Code and the regulations thereunder are substantially as
follows.
 
     Under the Code, the Company is considered to grant participants an "option"
on the first day of each calendar quarter to purchase as many shares of Common
Stock as the participant will be able to purchase with the payroll deductions
credited to his or her account during the calendar quarter. On the last day of
each calendar quarter, the market price is determined and the participant is
considered to have exercised the
 
                                        9
<PAGE>   12
 
"option" and purchased the number of shares of Common Stock his or her
accumulated payroll deductions will purchase at the market price.
 
     The required holding period for favorable tax treatment upon disposition of
Common Stock acquired under the Employee Stock Purchase Plan (the "Holding
Period") is the later of (a) two years after the "option" is granted (the first
day of a calendar quarter), or (b) one year after the Common Stock is purchased
(the last day of a calendar quarter). Consequently, if the Common Stock is held
for the required Holding Period, a participant who sells the shares will realize
ordinary income to the extent of the lesser of (1) the amount by which the fair
market value of the Common Stock at the time the option was granted exceeded the
"option price" or (2) the amount by which the fair market value of the Common
Stock at the time of the disposition exceeded the "option price." The "option
price" is determined on the date of grant for this purpose and, is therefore
equal to 85% of the fair market value of the Common Stock as of the first day of
a calendar quarter. Any further gain realized upon the sale will be considered a
long-term capital gain. If the sale price is less than the option price, there
will be no ordinary income and the participant will have a long-term capital
loss for the difference. The Company will not be entitled to a deduction for
federal income tax purposes with respect to the purchase or the subsequent
disposition of shares of Common Stock.
 
     When a participant sells Common Stock purchased under the Employee Stock
Purchase Plan before the expiration of the required Holding Period, the
participant will recognize ordinary income to the extent of the difference
between the price actually paid for the Common Stock and the fair market value
of the Common Stock at the date the option was exercised (the last day of a
calendar quarter), regardless of the price at which the Common Stock is sold. To
the extent the participant recognizes ordinary income on the sale of Common
Stock, the Company will generally receive a corresponding deduction in the year
in which the disposition occurs. Any gain realized in excess of that amount will
be taxed as a capital gain. If the sale price is less than the amount paid by
the participant, increased by the ordinary income which must be recognized, then
any such loss will be a capital loss.
 
     If a participant dies while owning Common Stock acquired under the Employee
Stock Purchase Plan, ordinary income must be reported on his or her final income
tax return. This amount will be the lesser of (1) the amount by which the fair
market value of the Common Stock at the time the option was granted exceeded the
option price (i.e., 15% of such fair market value), or (2) the amount by which
the fair market value of the Common Stock at the time of the participant's death
exceeded the option price.
 
     The foregoing discussion is only a general summary of the federal income
tax consequences of a purchase of Common Stock under the Employee Stock Purchase
Plan and the subsequent disposition of shares received pursuant to such
purchases. A participant should consult his or her own tax advisor to determine
the tax consequences of any particular transaction.
 
     The state income tax treatment of purchasing and selling the shares under
the Employee Stock Purchase Plan will vary depending upon the state in which a
participant resides. If the participant is a resident of, or is employed in, a
country other than the United States, the participant may be subject to taxation
in that country in addition to or instead of United States federal income taxes.
A participant should consult his or her own tax advisor regarding the tax
consequences and compliance requirements of any particular transaction.
 
     THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE ADOPTION OF THE EMPLOYEE
STOCK PURCHASE PLAN.
 
                             PROPOSAL NUMBER THREE
 
                AMENDMENT OF THE CERTIFICATE OF INCORPORATION TO
            INCREASE THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK
 
     The Board of Directors of the Company has adopted a resolution unanimously
approving and recommending to the Company's stockholders for their approval an
amendment to the current Certificate of Incorporation of the Company (the
"Certificate of Incorporation") increasing the number of authorized shares of
Common Stock of the Company from 50,000,000 to 100,000,000 shares.
 
                                       10
<PAGE>   13
 
     The Certificate of Incorporation currently provides that the Company is
authorized to issue up to 50,000,000 shares of Common Stock. The Board of
Directors of the Company declared a two-for-one stock split (the "Stock Split"),
effected in the form of a 100% stock dividend, that was paid April 15, 1998, to
stockholders of record as of the close of business on March 31, 1998.
Immediately following the Stock Split as of the close of business on April 15,
1998, 29,091,812 shares of Common Stock were issued and outstanding and an
additional 2,726,392 shares were reserved for issuance in connection with
existing benefit plans and outstanding warrants.
 
     The proposed amendment to the Certificate of Incorporation would increase
the number of authorized shares of Common Stock by 50,000,000 shares. The
additional shares of Common Stock for which authorization is sought, if and when
issued, would have the same rights and privileges as the shares of Common Stock
now outstanding.
 
     The Board of Directors recommends the increase in the authorized Common
Stock to enable the Company to have additional shares available for possible
issuance in connection with such general corporate purposes as future stock
splits and stock dividends, issuance of shares for cash to raise equity capital,
conversions of convertible securities, or in connection with business
acquisitions, stock option plans or other employee benefit plans which may be
adopted in the future. If the proposal to amend the Certificate of Incorporation
to increase the number of authorized shares of Common Stock is approved at the
Annual Meeting, the Board of Directors will have greater flexibility to issue
additional shares of Common Stock without the expense and delay of a
stockholders' meeting unless stockholder approval is otherwise required. The
Company has no current plans, agreements or arrangements for the issuance of
additional shares of Common Stock, other than in connection with the Company's
existing benefit plans.
 
     The issuance of additional shares of Common Stock could, under certain
circumstances, render more difficult or discourage an attempt by a third party
to obtain control of the Company. For example, the issuance of shares of Common
Stock in a public or private sale, merger, or similar transaction would increase
the number of the Company's outstanding shares, thereby diluting the interest of
a party seeking to acquire control of the Company and increasing the cost of
such transaction.
 
     Issuance of additional shares of Common Stock, depending upon the timing
and circumstances, could dilute earnings per share and decrease the book value
per share of shares theretofore outstanding and each stockholder's percentage
ownership of the Company may be proportionately reduced.
 
     The affirmative vote of the holders of at least a majority of the issued
and outstanding shares of Common Stock is needed for the approval of this
proposal. Abstentions and broker non-votes will have the same effect as a vote
against the proposal.
 
     THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE PROPOSAL TO AMEND THE
CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF
COMMON STOCK.
 
                              PROPOSAL NUMBER FOUR
 
                 RATIFICATION OF INDEPENDENT PUBLIC ACCOUNTANTS
 
     Stockholders will be asked to vote for a proposal to ratify the appointment
of Grant Thornton as the independent public accountants of the Company for the
fiscal year ending December 31, 1998. Grant Thornton has been the independent
public accountants for the Company since fiscal year 1989. If the stockholders,
by affirmative vote of the holders of a majority of the votes cast, do not
ratify this appointment, the Board of Directors will reconsider its action and
select other independent public accountants without further stockholder action.
Abstentions and broker non-votes will have no effect on Proposal Four.
 
     A representative of Grant Thornton is expected to be present at the Annual
Meeting to respond to appropriate questions and will be given the opportunity to
make a statement if such representative desires to do so.
 
                                       11
<PAGE>   14
 
     THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR
RATIFICATION OF THE APPOINTMENT OF GRANT THORNTON AS THE INDEPENDENT PUBLIC
ACCOUNTANTS OF THE COMPANY.
 
                      COMPLIANCE WITH FILING REQUIREMENTS
 
     Pursuant to Section 16(a) of the Securities Exchange Act of 1934, officers,
directors, and beneficial owners of more than ten percent of the outstanding
Common Stock are required to file reports with the Securities and Exchange
Commission reporting their beneficial ownership of the Common Stock at the time
they become subject to the reporting requirements and changes in beneficial
ownership occurring thereafter. Based on a review of the reports submitted to
the Company and written representations from persons known to the Company to be
subject to these reporting requirements, the Company believes that its executive
officers and directors complied with the Section 16(a) requirements during
fiscal 1997, except that one transaction of Mr. Klimkowski's was reported 14
days late.

                            THERAGENICS CORPORATION
                          EMPLOYEE STOCK PURCHASE PLAN
 
     1. Purpose.  The purpose of the Theragenics Corporation Employee Stock
Purchase Plan (the "Plan") is to provide employees of Theragenics Corporation
(the "Company") and its subsidiary companies with an opportunity to be
compensated through the benefits of stock ownership and to acquire an interest
in the Company through the purchase of Common Stock of the Company ("Common
Stock"). The Company intends the Plan to qualify as an employee stock purchase
plan under Section 423 of the Internal Revenue Code of 1986, as amended (the
"Code"). Accordingly, the provisions of the Plan shall be construed so as to
extend and limit participation in a manner consistent with the requirements of
Code Section 423.
 
     2. Definitions.  (a) "Authorization" means the authorization notice that
the Company will send to each eligible Employee each Calendar Quarter advising
the eligible Employee of his right to participate in the Plan for the ensuing
Calendar Quarter.
 
     (b) "Beginning Date" means January 1, April 1, July 1, and October 1.
 
     (c) "Calendar Quarter" means the following three-month periods: (i) January
1 to March 31, (ii) April 1 to June 30, (iii) July 1 to September 30, and (iv)
October 1 to December 31.
 
     (d) "Compensation" means the cash W-2 compensation, including Section
401(k) and Section 125 contributions, paid to an Employee by the Company or a
designated subsidiary or parent corporation with respect to a calendar year.
 
     (e) "Employee" means any person, including an officer, who: (i) is
customarily employed for more than twenty (20) hours per week; (ii) is
customarily employed for more than five (5) months per calendar year; and (iii)
an employee, determined in accordance with Section 3401(c) of the Code and the
regulations thereunder, of the Company or any subsidiary of the Company
designated from time to time by the Company's Board of Directors.
 
     (f) "Exercise Date" means March 31, June 30, September 30, and December 31.
 
     3. Eligibility.  (a) Any Employee who has been employed by the Company for
one year preceding the Beginning Date in each Calendar Quarter shall be eligible
to participate in the Plan for the ensuing Calendar Quarter.
 
     (b) No Employee shall be granted an option:
 
          (1) if, immediately after the grant that Employee would own shares,
     and/or hold outstanding options to purchase shares, possessing five percent
     (5%) or more of the total combined voting power or value of all classes of
     shares of the Company or of any parent corporation or subsidiary of the
     Company; or (2) which permits his rights to purchase shares under all
     employee stock purchase plans of the Company and its parent and subsidiary
     corporations to accrue at a rate which exceeds $25,000 of the fair market
     value of the shares (determined at the time the option is granted) for each
     calendar year in which such stock option is outstanding at any time.
 
     4. Offering Period.  Commencing October 1, 1998, the offering period shall
be the Calendar Quarter. Each Calendar Quarter will begin on a Beginning Date
and will end on the Exercise Date which occurs three months later. Each Calendar
Quarter, the Company will send an Authorization to each eligible Employee
advising him of his right to participate in the Plan for the ensuing Calendar
Quarter.
 
     5. Participation.  An eligible Employee may become a participant for a
Calendar Quarter by completing the Authorization and filing it with the Company
on or before the date established by the Company. Employees whose Authorizations
are received after that date may not participate in the Plan for that Calendar
Quarter. All Employees granted options under the Plan shall have the same rights
and privileges, except that
 
                                       A-1
<PAGE>   17
 
the amount of Common Stock which may be purchased under such options may vary in
a uniform manner according to Compensation.
 
     6. Method of Payment.  A participant may contribute to the Plan through
payroll deductions, as follows:
 
          (a) A participant shall on his Authorization elect to have deductions
     made from his Compensation on each payday during the Calendar Quarter at a
     rate which, expressed as a percentage, shall be at least one percent (1%)
     and not exceed ten percent (10%) of his Compensation.
 
          (b) All payroll deductions made for a participant shall be credited to
     his account under the Plan.
 
          (c) Payroll deductions for a participant shall commence on the first
     payday following the first day of each Calendar Quarter, and shall end on
     the last day of that Calendar Quarter, unless the participant sooner
     withdraws as authorized under Paragraph 10.
 
          (d) A participant may not alter the rate of his payroll deductions
     during the Calendar Quarter, except to stop payroll deductions. Any request
     to stop payroll deductions will be effective as of the first payroll period
     following the date of the processing of such request.
 
     7. Granting of Option.  (a) A participant shall be granted an option for a
number of shares of Common Stock for a Calendar Quarter, subject to the
adjustments provided for in Paragraph 15 of the Plan, determined according to
the following procedure:
 
     Step 1 Determine the amount of payroll deductions withheld for
participation in the Plan for the Calendar Quarter; Step 2 Determine the amount
which represents eighty-five percent (85%) of the lower of fair market value of
a share of Common Stock on the (i) Beginning Date or (ii) Exercise Date; and
Step 3 Divide the amount determined in Step 1 by the amount determined in Step 2
and round down the quotient to the nearest whole number.
 
     (b) In each Calendar Quarter, the option price of shares of Common Stock to
be purchased with a participant's payroll deductions shall be the lower of (i)
eighty-five percent (85%) of the fair market value of the shares on the
Beginning Date, or (ii) eighty-five percent (85%) of the fair market value of
the shares on the Exercise Date.
 
     (c) For purposes of the preceding subparagraph, the fair market value of a
share of Common Stock on the Beginning Date and the Exercise Date as of each
such date, or the most immediately preceding business day with respect to which
the information required in the following clauses is available, shall be
determined as follows: (i) if the Common Stock is traded on a national
securities exchange, the closing sale price on that date; (ii) if the Common
Stock is not traded on any such exchange, the closing sale price as reported by
the NASDAQ Stock Market; (iii) if no such closing sale price information is
available, the average of the closing bid and asked prices as reported by the
NASDAQ Stock Market; or (iv) if there are no such closing bid and asked prices,
the average of the closing bid and asked prices as reported by any other
commercial service.
 
     8. Exercise of Option.  A participant's option for the purchase of shares
during a Calendar Quarter will be automatically exercised for him on the last
day of that Calendar Quarter for the purchase of the maximum number of full
shares which the sum of the payroll deductions credited to the participant's
account on that Exercise Date can purchase at the option price.
 
     9. Delivery.  As soon as administratively feasible after each Exercise
Date, the Company shall deliver to each participant the shares purchased upon
the exercise of his option. The disposition of any payroll deductions credited
to his account during the Calendar Quarter not used for the purchase of shares
(the "Cash Excess") shall be credited to the participant's payroll deductions
for the next Calendar Quarter or, if the participant has stopped participating
in the Plan, the Cash Excess shall be returned to the participant.
 
     10. Withdrawal.  (a) A participant may withdraw payroll deductions credited
to his account under the Plan at any time during a Calendar Quarter by giving
written notice to the Company. A participant who for any reason, including
retirement or death, ceases to be an Employee prior to the Exercise Date during
any Calendar Quarter will be deemed to have withdrawn from the Plan on the date
of his retirement, death or other termination of employment.
 
                                       A-2
<PAGE>   18
 
     (b) Upon the withdrawal of a participant from the Plan under the terms of
subparagraph (a) above, the participant's outstanding options under this Plan
shall immediately terminate.
 
     (c) In the event a participant withdraws from the Plan for any reason, all
deductions credited to his account plus earnings thereon, if any, will be paid
to him, or, in the event of his death, to the person or persons entitled thereto
under the terms of Paragraph 14, as soon as administratively feasible after the
date of the participant's retirement or other termination of employment, or
after receipt by the Company of the participant's notice of withdrawal, or
notification of the participant's death, as the case may be. No further
deductions will be made from the participant's pay.
 
     (d) A participant's withdrawal will not have any effect upon his
eligibility to participate in the Plan during a subsequent Calendar Quarter.
 
     11. Stock.  (a) The shares of Common Stock to be sold to participants under
the Plan may, at the election of the Company, be either treasury shares or
shares originally issued for such purpose. The maximum number of shares made
available for sale under the Plan shall be 200,000 shares, subject to adjustment
upon changes in capitalization of the Company as provided in Paragraph 15. If
the total number of shares for which options are to be exercised in accordance
with Paragraph 8 exceeds the number of shares then available under the Plan, the
Company shall make a pro rata allocation of the shares available in as nearly a
uniform manner as shall be practicable and as it shall determine to be
equitable.
 
     (b) A participant will have no interest in shares covered by his option
until such option has been exercised.
 
     (c) Shares to be delivered to a participant under the Plan will be
registered in the name of the participant, or, if the participant so directs, by
written notice to the Company prior to the Exercise Date, in the names of the
participant and one other person designated by the participant, as joint tenants
with rights of survivorship, to the extent permitted by applicable law.
 
     (d) Shares of Common Stock purchased under the terms of the Plan by a
participant who is subject to Section 16 of the Securities Exchange Act of 1934
may not be sold prior to the expiration of six (6) months from the Exercise Date
upon which such shares were purchased except in the event of the participant's
disability, as determined by the Committee, or death.
 
     12. Administration.  The Plan shall be administered by a committee (the
"Committee") which shall consist of not less than two (2) members of the
Company's Board of Directors, who shall be appointed by the Board of Directors
of the Company. The Committee shall be vested with full authority to make,
administer, and interpret such rules and regulations as it deems necessary to
administer the Plan, and any determination or action of the Committee in
connection with the interpretation or administration of the Plan shall be final
and binding upon all participants and any and all persons claiming under or
through any participant. The Board of Directors of the Company may at any time
and from time to time remove members from, or add members to, the Committee, or
fill vacancies.
 
     13. Designation of Beneficiary.  (a) A participant may file with the
Company a written designation of a beneficiary who is to receive any cash to his
credit under the Plan in the event of his death before an Exercise Date, or any
shares of Common Stock and cash to his credit under the Plan in the event of his
death on or after an Exercise Date but prior to the delivery to him of such
shares and cash. A beneficiary may be changed by the participant at any time by
notice in writing to the Company.
 
     (b) Upon the death of a participant and upon receipt by the Company of
proof of the identity and existence at the time of the participant's death of a
beneficiary designated by him in accordance with the preceding subparagraph, the
Company shall deliver such shares and/or cash to the beneficiary. In the event a
participant dies not survived by a then living or in existence beneficiary
designated by him in accordance with the preceding subparagraph, the Company
shall deliver such shares and/or cash to the personal representative of the
estate of the deceased participant. If to the knowledge of the Company no
personal representative has been appointed within ninety (90) days following the
date of the participant's death, the Company, in its discretion, may deliver
such shares and/or cash to the surviving spouse of the deceased participant, or
to any
 
                                       A-3
<PAGE>   19
 
one or more dependents or relatives of the deceased participant, or if no
spouse, dependent, or relative is known to the Company then to such other person
as the Company may designate.
 
     (c) No designated beneficiary shall, prior to the death of the participant
by whom he has been designated, acquire any interest in the shares or cash
credited to the participant under the Plan.
 
     14. Transferability.  Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged, or
otherwise disposed of in any way by the participant. Any attempted assignment,
transfer, pledge, or other disposition shall be without effect, except that the
Company may treat such act as an election to withdraw funds in accordance with
Paragraph 10.
 
     15. Adjustments Upon Changes in Capitalization.  In the event that the
outstanding shares of Common Stock of the Company are hereafter increased or
decreased or changed into or exchanged for a different number or kind of shares
or other securities of the Company by reason of a recapitalization,
reclassification, stock split, combination of shares, or dividend payable in
shares of Common Stock, an appropriate adjustment shall be made by the Committee
to the number and kind of shares available for the granting of options, or as to
which outstanding options shall be exercisable, and to the option price. No
fractional shares shall be issued or optioned in making any such adjustments.
All adjustments made by the Committee under this paragraph shall be conclusive.
 
     Subject to any required action by the stockholders, if the Company shall be
a party to any reorganization involving merger, consolidation, acquisition of
the stock or acquisition of the assets of the Company, the Committee in its
discretion may declare (a) that all options granted hereunder are to be
terminated, or (b) that any option granted hereunder shall pertain to and apply
with appropriate adjustment as determined by the Committee to the securities of
the resulting corporation to which a holder of the number of shares of Common
Stock subject to the option would have been entitled. The adoption of a plan of
dissolution or liquidation by the Company shall cause every option outstanding
hereunder to terminate, except that, in the event of the adoption of a plan of
dissolution or liquidation in connection with a reorganization as provided in
the preceding sentence, options outstanding hereunder shall be governed by the
provisions of the preceding sentence.
 
     Any issue by the Company of any class of preferred stock, or securities

THERAGENICS CORPORATION 1997 ANNUAL REPORT


(Back cover; business description)

Theragenics  is a leader in the  production  and sale of  implantable  radiation
devices  used in the  treatment  of  cancer.  The  Company  produces  and  sells
TheraSeed(R): a FDA-licensed device that is for use in solid localized tumors.

The  Company's  devices are most  effective on  encapsulated,  confined  tumors.
TheraSeed(R)  is based on  established  physical  principles  and has the simple
objective of  delivering  sufficient  radiation to the target  cancer to kill it
while minimizing the radiation to surrounding tissue.

The conventional treatments for cancer to date have been surgery,  radiation and
chemotherapy.  The  treatments  that have been most  successful  are those which
remove or kill all of the cancerous  tissue while avoiding  excessive  damage to
the surrounding healthy, normal tissue.

In the  treatment  of prostate  cancer,  TheraSeeds(R)  are  implanted  into the
prostate in a one-time,  minimally  invasive  procedure.  Prostate cancer is the
most common form of cancer,  and the second  leading  cause of cancer  deaths in
men.  It is  expected  to account  for  approximately  43% of all  cancers to be
diagnosed in men during 1998.

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 recovery time and incidence of side effects.

OUR PROGRESS
THROUGHOUT
1997


Theragenics'  magnificent  year is a result  of much  more  than  our  financial
statements.   Recognizing  this,  I  will  address  the  issues,  identify  some
milestones,  discuss  market forces and touch on 1998. I encourage you to review
the strong financial performance noted throughout this report.

Operations
We  produced a record  number of  TheraSeeds(R)  during  1997.  While  keeping a
watchful eye on this expanded  production,  our Radiation  Safety and Regulatory
Affairs Departments also delivered unprecedented  accomplishments this year. The
Radiation  Safety  team  maintained  a  perfect  record  on  our  yearly  safety
inspection  conducted  by the State of  Georgia.  The  Regulatory  Affairs  team
procured our ISO 9001  certification  in an incredibly  short six-month  period.
This is an  impressive  feat  given the  complexity  and  sophistication  of our
operations.

Automation of our tedious  hand-assembly  process continues to disappoint us. We
severed  ties with our  vendors  this year and  started  to work with an outside
group that has experience  with aerospace and esoteric  technologies.  It is our
intention to get this back on track during 1998 and finished by the end of 1999.

Our  cyclotron  capacity  increased  twofold this year.  We currently  have four
cyclotrons  in  operation.  During 1998,  we plan to add one new  cyclotron  per
quarter for a total of eight operational by the end of the year. When completed,
our existing capacity will double,  making us the largest cyclotron operation in
the world.  The building and cyclotrons are expected to cost  approximately  $28
million.

Looking  forward  and  putting in place the  underpinnings  for our  future,  we
recently  announced  the  signing  of  agreements  to  purchase  six  additional
cyclotrons to be installed by year-end 1999.

Just a few short  years ago, we had only 32  employees;  today we have more than
120. Our  employees  were the  linchpin of our success this past year.  They are
incredibily  resourceful,  motivated and highly focused on quality output. Their
dedication to Theragenics,  our customers and our patients is humbling.  We plan
to recognize  their efforts by  continuing  to improve our safety,  training and
benefit  programs.  This year, we are  investing in our most  valuable  asset by
enhancing our employee benefits package.  This package will include a bonus plan
based on profit and revenue,  a credit  union,  a stock purchase plan and new
401(k) plan.  Additionally, we enhanced the dental and life insurance coverage
for all employees.  We believe these investments will help us attract and retain
the brightest and the best talent in what has become a very tight labor market.

MILESTONES
Two pivotal  events  during 1997 forever  changed the face of  Theragenics.  The
first was a secondary  stock  offering in March 1997.  We raised more money than
ever  before  in our  history.  By  doing  so,  we  increased  our  exposure  to
institutional  shareholders,  attracted positive attention from several industry
analysts,  enjoyed additional  corporate exposure though positive media coverage
and set the stage for current and future manufacturing expansion.
<PAGE>   23

Secondly,  we signed an exclusive,  worldwide  marketing  agreement  with Indigo
Medical,  a Johnson & Johnson  company.  This  agreement  grants Indigo  Medical
marketing and sales rights to our prostate  cancer  business.  As the number one
healthcare company in the world,  Johnson & Johnson is a partner of the size and
stature we believe can drive the  prostate  cancer  treatment  market to heights
heretofore  unheard of in brachytherapy  or urology.  The export of TheraSeed(R)
into international  markets is an additional growth opportunity  enhanced by our
relationship with Indigo Medical.  Through this collaboration we have reaffirmed
our commitment to the economical and clinically  effective treatment of prostate
cancer.

THE INDUSTRY
Our agreement with Indigo,  the clinical success of  brachytherapy  for prostate
canceR and public awareness have mushroomed demand for seeds. There are no less
than  six new  companies  planning  to  manufacture  isotopes  intended  for the
treatment of prostate  cancer.  We believe  most of them have little  commercial
production  experience in this  industry.  We will closely  monitor  competitive
activities  during the next two years.  Theragenics was the first to market with
its  palladium  product.  Our place as a pace setter  dictates  that we position
ourselves  for  dynamic  events.  The  technical  and  financial   strengths  of
Theragenics  and our  partner's  marketing  expertise  put us in a  position  of
readiness.

Although the American Cancer Society  adjusted  downward the number of new cases
of prostate  cancer in 1997,  we entered  1998 with only a 5% market  share.  We
expect the next  several  years to see  continued  sales  growth and forecast no
deterioration of our market potential.  While the  biotechnology  industry has a
history  of  volatility,  Theragenics  faces  1998 and  beyond  backed by a rich
history of results.  While we are not immune to trouble, we do have an effective
product,  a substantial  partner,  significant  profit and clinical results that
indicate we cure cancer.

CANCER
More  patients were treated with  TheraSeed(R)  during 1997 than in any previous
two-year  period.  As a result of the increase in demand for  TheraSeed(R),  our
Cancer  Information  Center  doubled  in size and the  number  of calls for help
quadrupled year over year.

The future  success of  TheraSeed(R)  or any  product for  prostate  cancer will
depend on clinical data. I'm proud to report that our product holds up admirably
as the clinical studies continue to mature. Most notably, Dr. John Blasko of the
University of Washington in Seattle reported 91%  disease-free  results at eight
years.  In a separate study, early-stage patients of Dr. Michael  Dattoli of the
University  Community  Hospital in Tampa  experienced a 93% disease-free rate at
six years.  Additionally,  Dr. Dattoli reported a 79% disease-free  rate at five
years for his advanced,  early-stage high-risk patients using a modified dose of
external beam radiation  followed by the  implantation  of  TheraSeed(R).  These
outcomes  are  exceptional  given this group of men was faced with very few, if
any, options for treatment. These results are staggering,  positive and material
when compared to conventional treatment outcomes.

To close, our mission is to cure at least one patient of cancer with every order
we ship. At Theragenics, this is what we do for a living. We execute our mission
first with a commitment  to quality.  Then we see to the business of  delivering
value to our customers,  employees, patients and shareholders. We appreciate and
thank you for your support this year and in the past.

Sincerely,

M. Christine Jacobs
Co-Chairman, CEO and President

My mission is to maintain a safe working environment
(Image:  Watermark of the word Safety)

The safety and security of our employees are paramount issues at Theragenics.
We promote a safe working environment by implementing safety procedures that go
beyond those required by  tate and federal guidelines.  To uphold our standards,
we continually  monitor, control and work to reduce our employees' exposure to
radiation.

To further maintain a safe and secure environment, my job is not only focused on
employee  exposure, but also on the proper placement, storage and disposal of
radioactive materials.

As Theragenics  continues to grow, my goal is to maintain the highest  standards
and controls to ensure the continued  safety and well-being of our employees and
our environment.

My mission is to ensure high quality operating procedures
(Image:  Watermark of the word Quality)

When I came to work at  Theragenics,  I never in my  wildest  dreams  could have
imagined that my job would transition into the opportunities  being presented to
me  today.  As  Quality  Systems  Technician,  my goal is to ensure  that  every
customer  receives  the highest  quality  product.  This  quality is achieved by
assembling  each  TheraSeed(R)  with the  utmost  attention  to  detail.  Due to
TheraSeed's(R)  delicate and intricate components,  the current assembly process
is achieved through the mastery of precision hand assembly. Each TheraSeed(R) is
subjected to several  inspections  followed by a  qualitative  and  quantitative
analysis to assure it has met all quality standards.  With these steps in place,
we're confident our customers receive a safe and reliable product.

As the demand for  TheraSeed(R)  continues to grow, we're always looking for and
implementing new and better ways to assemble our product more efficiently  while
maintaining our high standards.

My mission is ensuring that we adhere to all quality and regulatory standards
(Watermark of the word Regulatory)

My  top  three  priorities  for  the  Regulatory  Affairs  and  Quality  Systems
Departments  are to establish  and maintain  systems that enhance the quality of
our products and services, to ensure compliance with all applicable  regulations
and to gain access to world  markets so that cancer  patients  can benefit  from
treatment with TheraSeed(R).

Knowing that the manufacture  and sale of TheraSeed(R)  are subject to stringent
government  regulations - like any other medical device - we consistently adhere
to regulations  such as the FDA's Good  Manufacturing  Practices,  which include
extensive   record   keeping,   reporting  and  periodic   inspections   of  our
manufacturing facilities.

During  1997,  we achieved  ISO 9001  certification  in just six months - a time
period shorter than everyone's expectations. The ISO 9001 registration certifies
that  the  Company's  quality  systems  meet  or  exceed  international  quality
standards.  ISO 9001 certification represents a step toward attaining a CE Mark,
Europe's  standard  equivalent to U.S. FDA approval.  CE Mark  certification can
open the door for  marketing and selling  TheraSeed(R)  to the 15 nations of the
European Union, expanding on TheraSeed's(R) continuing success in the U.S.

My mission is to maintain high production capacity without compromising quality

I came to this country from Africa 15 years ago, originally to study mathematics
and later to study  nursing.  Although  I am not a nurse,  I am happy that I can
still help cancer patients  through my work at  Theragenics.  I am excited about
where this  Company is going and believe it is a place where I can build a solid
career and future for myself.

With the growing demand for TheraSeed(R), increasing our production capacity and
efficiency  has become more  critical than ever before.  To meet these  demands,
we're adding four new cyclotrons  during 1998 and six in 1999.  The  cyclotrons,
which  are  used  to  manufacture   palladium   103,  the  core   ingredient  in
TheraSeed(R),   will  greatly  enhance  our  sales,   performance  and  customer
satisfaction   levels.  In  conjunction  with  the  increase  in  palladium  103
production, we also will expand our assembly and quality operations.

I am excited  about  moving  into our new  facility  located in Buford,  Georgia
during  1998.  This  facility  will  bring  together  all of  our  manufacturing
operations  under one roof,  making our operations and channels of communication
better and more efficient.

As we begin to expand our facility and  continue to  investigate  new methods of
production,  we're still mindful of selecting cutting-edge ideas, procedures and

Management's Discussion and Analysis of Financial Conditions 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  palladium  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  palladium  103,  the  Company
converted  from  reactor  produced  palladium  103 to an  alternative  means  of
producing  palladium 103 using a cyclotron.  In 1992, the Company contracted for
the purchase of a cyclotron for in-house  production of palladium 103. After the
cyclotron  was   delivered   and  reliable   production  of  palladium  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.
<PAGE>   28

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 $2.4million, 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.

Otherincome (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.
<PAGE>   29

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 palladium 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 recognize  dates  properly 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, SG&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
<PAGE>   30

health care  professionals,  competition  from  conventional and newly developed
methods of treating  localized cancer and dependence on a third-party  cyclotron
manufacturer.

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.

NOTES TO FINANCIAL STATEMENTS

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. 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 1995,
1996 and 1997,  respectively.  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.
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
placed in service during 1996 and 1997, respectively.

NOTE D
Income Taxes
The provision for income taxes is summarized as follows:

                                1995           1996           1997
Current tax expense       $    18,000     $   95,500      $ 3,500,000
Deferred tax expense        1,082,000      1,972,000        1,850,000
                          $ 1,100,000     $2,067,500      $ 5,350,000
The Company's  temporary  differences  result in a deferred  income tax asset at
December  31, 1996 and a deferred  income tax  liability  at December  31, 1997,
summarized as follows:

December 31,                                      1996              1997

Net deferred tax asset (liability)         $       360,000    $(1,000,000)

The provision for income taxes differs from the amount of income tax  determined
by applying the applicable federal rates due to the following:

                                  1995           1996                1997

                         $  1,100,000       $ 2,067,500       $    5,350,000

NOTE E
Notes Payable
The Company has entered into an amended and restated loan and security agreement
("the loan agreement") with a bank. The loan agreement  provides for a revolving
credit  facility of up to  $15,000,000.  Interest on  outstanding  borrowings is
payable monthly at the prime rate or at a LIBOR-based rate.
The  LIBOR-based  rate  ranges  from  LIBOR  plus 1.5% to LIBOR  plus 2%, and is
determined by the Company's debt service  coverage ratio, as defined in the loan
agreement.  At December 31, 1996, $3,458,436 was outstanding under the revolving
credit  facility  with an  effective  interest  rate of 8.25%.  No amounts  were
outstanding   under  the  revolving  credit  agreement  at  December  31,  1997.
Outstanding   borrowings  under  the  loan  agreement  are   collateralized   by
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 F
Commitments and Contingencies
Marketing and Sales Agreement

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:
