        set forth in the Loan Documents shall be joint and several obligations of
        all
        Borrowers. All representations and warranties of Borrower shall be deemed
        representations and warranties made by each Borrower, unless the context
        expressly provides otherwise. Each Borrower hereby irrevocably appoints
        Theragenics Corporation as borrowing agent for each Borrower ("Borrowing
        Agent"), and Borrowing Agent shall act under this Agreement as the agent
        and

        or a LIBOR Rate Borrowing, and receiving account statements and other notices
        and  communications
        to any Borrower from Bank. No notice to a Borrower shall be effective
        unless  the
        same
        is given (or a copy thereof is given) to the Borrowing Agent. Bank may rely,
        and
        shall  be
        fully
        protected in relying, on any notice or request for any Loan or Letter of
        Credit,  disbursement
        instructions, reports, information or any other notice or communication made
        or  given
        by
        Borrowing Agent, whether in its own name, on behalf of any individual Borrower
        or on  behalf
        of
        each Borrower, and Bank shall have no obligation to make any inquiry or request
        any  confirmation
        from or on behalf of any other Borrower as to the binding effect on such
        Borrower
   -3-
  of
        any
        such request, instruction, report, information, notice or communication,
        nor
        shall the joint  and
        several character of each Borrower's liability for the Obligations be
        affected.
  2.9** All
        Loans Constitute One Obligation; Joint and Several Liability. The Loans
        and  all
        other
        Obligations shall constitute one general obligation of each Borrower, jointly
        and  severally,
        on a combined basis and shall be secured by Bank's Lien (if any) upon all
        of
        the  Collateral
        (subject to the limitations in Section 8.1(C)). Each Borrower has requested
        that
        Bank  make
        available the Loans and Letters of Credit to each Borrower to finance their
        mutual and  collective
        enterprises. In order to utilize the financial powers of each Borrower on
        a
        combined  basis
        and
        in the most efficient and economical manner, and in order to facilitate the
        financing of  each
        Borrower's needs, Bank will make Loans to, and issue Letters of Credit on
        behalf
        of, each  Borrower
        on a combined basis and in accordance with the provisions herein set forth.
        The  businesses
        of each Borrower are a mutual and collective enterprise, and each Borrower
        believes  that
        the
        consolidation of all Obligations under this Agreement will enhance the
        aggregate  borrowing
        powers of each Borrower and ease the administration of their credit relationship
        with  Bank,
        all
        to the mutual advantage of each Borrower. Bank's willingness to extend credit
        to
        each  Borrower
        and to administer the Collateral therefor, on a combined basis as more fully
        set
        forth in  this
        Agreement, is done solely as an accommodation to each Borrower and at their
        request in  furtherance
        of their mutual and collective enterprise. Each Borrower shall be liable
        for, on
        a joint  and
        several basis, and hereby guarantees the timely payment by each Borrower
        of, all
        of the  Loans
        and
        other Obligations, regardless of which Borrower actually may have received
        the  proceeds
        of any Loan or the benefit of any Letter of Credit hereunder or the amount
        of
        such  Loans
        received or the manner in which Bank accounts for such Loans or Letters of
        Credit on its  books
        and
        records, it being acknowledged and agreed that Loans to, or Letters of Credit
        issued on  behalf
        of, any Borrower inure to the mutual benefit of each Borrower and that Bank
        is
        relying on  the
        joint
        and several liability of each Borrower in extending the Loans and issuing
        Letters of  Credit
        hereunder. Each Borrower hereby unconditionally and irrevocably agrees that
        upon  default
        in the payment when due (whether at stated maturity, by acceleration or
        otherwise) of any  principal
        of, or interest owed on, any of the Loans or other Obligations, such Borrower
        shall  forthwith
        pay the same, without notice or demand, if such default is not cured within
        any  applicable
        grace period.
 
 2.10         
        Unconditional Nature of Liability. Each Borrower's joint and several
        liability  hereunder
        with respect to, and guaranty of, the Loans and other Obligations shall,
        to the
        fullest  extent
        permitted by applicable law, be unconditional, irrespective of (i) the
        validity,  enforceability,
        avoidance or subordination of any of the Obligations or of any promissory
        note
        or  other
        document evidencing all or any part of the Obligations, (ii) the absence
        of any
        attempt to  collect
        any of the Obligations from any other obligor or any Collateral or other
        security therefor,  or
        the
        absence of any other action to enforce the same, (iii) the waiver, consent,
        extension,  forbearance,
        granting of any indulgence or departure from any Loan Document provision
        by  Bank
        with
        respect to any of the Obligations or any instrument or agreement evidencing
        or  securing
        the payment of any of the Obligations, or any other agreement now or hereafter
        executed  by
        any
        other Borrowers and delivered to Bank, (iv)
        the
        failure by Bank to take any steps to  perfect
        or maintain the perfected status of any security interest in or Lien upon,
        or to
        preserve its  rights to**,** any
        of
        the Collateral or other security for the payment or performance of any of
        the  Obligations,
        or Bank's release or exchange of any Collateral or of its Liens upon any
        Collateral,  (v)
        Bank's election, in any proceeding instituted under the Bankruptcy Code,
        for the
        application  of
        Section 111l(b)(2) of the Bankruptcy Code, (vi) any borrowing or grant of
        a
        security interest  by
        any
        other Borrower, as debtor-in-possession under Section 364 of the Bankruptcy
        Code, (vii)  the
        release or compromise, in whole or in part, of the liability of any Borrower,
        any guarantor,  any
        surety or any other obligor for the payment of any of the Obligations, (viii)
        any amendment
    -4-
  or
        modification of any of the Loan Documents or waiver of any Default or Event
        of
        Default  thereunder
        (but subject to the terms of such amendment, modification or waiver), (ix)
        any  increase
        in the amount of the Obligations beyond any limits imposed herein or in the
        amount of  any
        interest, fees or other charges payable in connection therewith, or any decrease
        in the same,  (x)
        the
        disallowance of all or any portion of Bank's claims against another Borrower
        for
        the  repayment
        of any of the Obligations under Section 502 of the Bankruptcy Code, or (xi)
        any
        other  circumstance
        that might constitute a legal or equitable discharge or defense of any Borrower,
        any  guarantor,
        any surety or any other obligor as a
        result
        of their status as a
        guarantor, surety or other  obligor
        under law or equity. At any time an Event of Default exists, Bank may proceed
        directly  and
        at
        once, without notice to any Borrower, any guarantor, any surety or any other
        obligor,  against
        any Borrower, any guarantor, any surety or any other obligor to collect and
        recover all or  any
        part
        of the Obligations, without first proceeding against any other Borrower,
        guarantor, surety  or
        other
        obligor or against any Collateral or other security for the payment or
        performance of any  of
        the
        Obligations, and each Borrower waives any provision that might otherwise
        require
        any  Bank
        under applicable law to pursue or exhaust its remedies against any Collateral
        or
        any  Borrower,
        any guarantor, any surety or any other obligor before pursuing such Borrower,
        such  guarantor,
        such surety or such other obligor. Each Borrower consents and agrees that
        Bank
        shall  be
        under
        no obligation to marshal any assets in favor of any Borrower, any guarantor,

        or
