arrangement,  the said  compromise or  arrangement  and the said  reorganization

shall,  if sanctioned by the court to which the said  application has been made,

be  binding  on all the  creditors  or class  of  creditors,  and/or  on all the

                          CERTIFICATE OF INCORPORATION

                             THERAGENICS CORPORATION

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

 

(Pursuant to Section 242 of the Delaware General Corporation Law)

 

         It is hereby certified:

         FIRST: The Certificate of Incorporation of Theragenics Corporation (the

"Corporation")  was filed by the  Secretary  of State of Delaware on November 6,

1981 under the name Nuclear  Medicine,  Inc. An amendment  was filed on June 16,

                  II.      Indemnification and Insurance.

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

                      (a)  Right to Indemnification.

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

         (i) Each person who was or is made a party or is  threatened to be made

         a party to or is  involved  in any  threatened,  pending  or  completed

         action, suit or proceeding, whether civil, criminal,  administrative or

         investigative (hereinafter a "proceeding"),  by reason of the fact that

         he or she,  or a person of whom he or she is the legal  representative,

         is or was a director or officer of the Corporation or is or was serving

         at the request of the Corporation as a director,  officer,  employee or

         agent of another corporation or of a partnership,  joint venture, trust

         or other enterprise, including service with respect to employee benefit

         plans,  whether the basis of such  proceeding  is alleged  action in an

         official capacity as a director,  officer,  employee or agent or in any

         other capacity while serving as a director, officer, employee or agent,

         shall  be  indemnified  and held  harmless  by the  Corporation  to the

         fullest extent  authorized by the Delaware General  Corporation Law, as

         the same exists or may  hereafter be amended  (but,  in the case of any

         such  amendment,  only to the extent  that such  amendment  permits the

         Corporation  to provide  broader  indemnification  rights than said law

         permitted the Corporation to provide prior to such amendment),  against

         all expense,  liability and loss (including attorneys' fees, judgments,

         fines,  ERISA excise taxes or penalties  and amounts paid or to be paid

         in  settlement)  reasonably  incurred  or  suffered  by such  person in

         connection  therewith and such  indemnification  shall continue as to a

         person who has ceased to be a director,  officer, employee or agent and

         shall  inure  to  the  benefit  of  his or  her  heirs,  executors  and

         administrators;   provided,   however,  that,  except  as  provided  in

         subparagraph  (b) hereof,  the  Corporation  shall  indemnify  any such

         person seeking indemnification in connection with a proceeding (or part

         thereof)  initiated  by such  person only if such  proceeding  (or part

         thereof) was authorized by the board of directors of the Corporation.

                  (ii) The right  indemnification  conferred  in this  Paragraph

         shall be a contract right and shall include the right to be paid by the

         Corporation  the expenses  incurred in defending any such proceeding in

         advance  of its final  disposition;  provided,  however,  that,  if the

<PAGE>

        

         Delaware General Corporation Law requires, the payment of such expenses

         incurred by a director or officer in his or her  capacity as a director

         or officer  (and not in any other  capacity in which  service was or is

         rendered by such person while a director or officer, including, without

         limitation,  service  to an  employee  benefit  plan) in advance of the

         final disposition of a proceeding,  shall be made only upon delivery to

         the Corporation of an undertaking,  by or on behalf of such director or

         officers,  to repay all amounts so advanced if it shall  ultimately  be

         determined in accordance with subparagraph (a) (iii) that such director

         or officer is not entitled to be  indemnified  under this  Paragraph or

         otherwise.  The  Corporation  may, by action of its Board of Directors,

         provide indemnification to employees and agents of the Corporation with

         the same scope and effect as the foregoing indemnification of directors

         and officers.

                  (iii) Any  indemnification  of a director  of the  Corporation

         under  Subparagraph (a) (i) hereof (unless ordered by a court) shall be

         made by the Corporation  only as authorized in the specific case upon a

         determination  that  indemnification  of the  director is proper in the

         circumstances because he has met the applicable standard of conduct set

         forth in the Delaware General  Corporation Law. Any  indemnification of

         an officer, employee or agent of the Corporation under subparagraph (a)

         (i) hereof (unless ordered by a court) shall be made by the Corporation

         upon a determination that  indemnification of the officer,  employee or

         agent is proper in the circumstances  because he has met the applicable

         standard of conduct set forth in the Delaware General  Corporation Law.

         Any such determination shall be made (i) by the Board of Directors by a

         majority  vote of a  quorum  consisting  of  Directors  which  were not

         parties to such action, suit or proceeding, or (ii) if such a quorum is

         not  obtainable,  or,  even if  obtainable  a quorum  of  disinterested

         Directors  so  directs,  by  independent  legal  counsel  in a  written

         opinion, or (iii) by the stockholders.

                  (b)       Right of Claimant to Bring Suit.

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

         If a claim under subparagraph (a) of this Paragraph is not paid in full

         by the  Corporation  within  thirty days after a written claim has been

         received by the  Corporation,  the claimant may at any time  thereafter

         bring suit against the  Corporation to recover the unpaid amount of the

         claim and, if  successful  in whole or in part,  the claimant  shall be

         entitled to be paid also the  expense of  prosecuting  such  claim.  It

         shall be a defense to any such action (other than an action  brought to

         enforce a claim for expense  incurred in defending  any  proceeding  in

         advance of its final disposition where the required undertaking, if any

         is required,  has been tendered to the  Corporation)  that the claimant

         has not met the  standards of conduct which make it  permissible  under

         the Delaware  General  Corporation Law for the Corporation to indemnify

         the  claimant  for the amount  claimed,  but the burden of proving such

         defense  shall  be on  the  Corporation.  Neither  the  failure  of the

         Corporation  (including  its  Board  of  Directors,  independent  legal

         counsel, or its stockholders) to have made a determination prior to the

         commencement  of such action that  indemnification  of the  claimant is

         proper in the  circumstances  because he or she has met the  applicable

         standard of conduct set forth in the Delaware General  Corporation Law,

         nor an actual determination by the Corporation  (including its Board of

         Directors,  independent legal counsel,  or its  stockholders)  that the

         claimant has not met such  applicable  standard of conduct,  shall be a

         defense to the action or create a presumption that the claimant has not

         met the applicable standard of conduct.

                  (c)  Non-Exclusivity  of Rights.  The right to indemnification
