Line of Credit Facility Expiration Date, as requested by Borrower in
accordance with the terms of Section 2.2 hereof, up to a maximum principal
amount at any time outstanding equal to the Line of Credit Maximum
Availability.  The Line of Credit Loans shall be evidenced by the Line of
Credit Note.  If the unpaid balance of the Line of Credit Loans should
exceed the Line of Credit Maximum Availability or any other limitation set

constitute Obligations that are secured by the Collateral and entitled to
all benefits thereof.  In no event shall Borrower be authorized to request
a Line of Credit Loan at any time that there exists a Default or an Event
of Default or at any time on or after the Line of Credit Facility
Expiration Date.  Nothwithstanding anything herein to the contrary, the sum
of the aggregate outstanding principal balance of the Line of Credit Loans
and the Revolving Credit Loans at any one time plus the aggregate stated
amount of all Letters of Credit (other than Cash-Secured Letters of Credit)
then outstanding may not exceed the sum of the Line of Credit Maximum
Availability  plus the Revolving Credit Maximum Availability as then in
effect

       (B)  Insofar as Borrower may request and Lender may be willing in

exceed with the making of such Line of Credit Loan, the Line of Credit
Maximum Availability (any such Loan or Loans being herein referred to
individually as a "Line of Credit Overadvance" and collectively as "Line of
Credit Overadvances"), Lender shall enter such Line of Credit Overadvances
as debits in the Loan Account.  All Line of Credit Overadvances shall be 

Page 58

repaid on demand and shall be evidenced by the Line of Credit Note.

       (C)  The Line of Credit Loans shall be used solely for Borrower's
general corporate needs, for capital expenditures as outlined on Schedule
1.1, all to the extent not inconsistent with the provisions of this
Agreement.

  2.2. Manner of Borrowing Line of Credit Loans.  Borrowings under the Line
of Credit Facility established pursuant to Section 2.1 shall be as follows:

       (A)  A request for a Line of Credit Loan shall be made, or shall be
deemed to be made, in the following manner:  (i) Borrower may give Lender
notice of its intention to borrow, in which notice Borrower shall specify
the amount of the proposed borrowing, the proposed borrowing date and that
such borrowing is to be a Line of Credit Loan; (ii) the becoming due of any
other Obligation shall be deemed irrevocably, at Lender's discretion,  to
be a request for a Line of Credit Loan on the due date in the amount then
so due and (iii) pursuant to the terms of Borrower's FOCUS account
agreement or similar account agreement with Lender;

       (B)  Borrower hereby irrevocably authorizes Lender to disburse the
proceeds of each Line of Credit Loan requested, or deemed to be requested,
pursuant to this Section 2.2 as follows:  (i) the proceeds of each Line of
Credit Loan requested under Section 2.2(A)(i) shall be disbursed by Lender
in lawful money of the United States of America in immediately available
funds, in the case of the initial borrowing, in accordance with the terms
of the written disbursement letter from Borrower, and in the case of each
subsequent borrowing, by wire transfer to such bank account as may be
agreed upon by Borrower and Lender from time to time; and (ii) the proceeds
of each Line of Credit Loan requested under Section 2.2(A)(ii) shall be
disbursed by Lender by way of direct payment of the relevant Obligation.

  2.3. Loan Account.  Lender shall enter all Line of Credit Loans as debits
to the Line of Credit Loan Account and shall also record in the Line of
Credit Loan Account all payments made by Borrower on Line of Credit Loans
and all proceeds of Collateral which are finally paid to Lender, and may
record therein, in accordance with customary accounting practice, all
charges and expenses properly chargeable to Borrower hereunder.

  2.4. Interest.  (A)  Interest shall accrue on the principal amount of the
Line of Credit Loans in accordance with the terms of the Line of Credit
Note.

       (B)  Borrower may prepay the Line of Credit Note in whole or in part
in accordance with the terms and conditions of the Line of Credit Note.

       (C)  In no contingency or event whatsoever shall the aggregate of
all amounts deemed interest hereunder or under the Line of Credit Note and
charged or collected pursuant to the terms of this Agreement or pursuant to
the Line of Credit Note exceed the highest rate permissible under any law
which a court of competent jurisdiction shall, in a final determination, 

Page 59

deem applicable hereto.  In the event that such a court determines that
Lender has charged or received interest hereunder in excess of the highest
applicable rate, Lender shall promptly refund such excess interest to
Borrower and such rate shall automatically be reduced to the maximum rate
permitted by such law.

  2.5  Term Loan.  Lender has made a term loan to Borrower in the original
principal amount of Two Million One Hundred Thousand and No/100 Dollars
($2,100,000).  Such term loan is evidenced by the Term Note.  The principal
and interest on the Term Note shall be payable in accordance with the terms
of the Term Note.



  SECTION 3.  REVOLVING CREDIT FACILITY

request therefor, as follows:

shall make Revolving Credit Loans to Borrower from time to time prior to
the Revolving Credit Facility Expiration Date in accordance with the terms
of Section 3.2 hereof, up to a maximum principal amount at any time
outstanding equal to the Revolving Credit Maximum Availability.  The
Revolving Credit Loans shall be evidenced by the Revolving Credit Note.  It
is expressly understood and agreed that the Revolving Credit Maximum
Availability shall be the maximum ceiling on Revolving Credit Loans
outstanding to Borrower at any time.  No Revolving Credit Loans shall be
requested by Borrower at any time that there exists a Default or an Event
of Default or at any time on or after the Revolving Credit Facility
Expiration Date.  Nothwithstanding anything herein to the contrary, the sum
of the aggregate outstanding principal balance of the Line of Credit Loans
and the Revolving Credit Loans at any one time plus the aggregate stated
amount of all Letters of Credit (other than Cash-Secured Letters of Credit)
then outstanding may not exceed the sum of the Line of Credit Maximum
Availability  plus the Revolving Credit Maximum Availability as then in
effect

       (B)  Upon the occurrence on or prior to the Revolving Credit
Facility Expiration Date of a Step-Up Event and provided that no Default or
Event of Default shall have occurred and be continuing at the time of such
occurrence, the Revolving Credit Maximum Availability shall increase from
$2,000,000 to $4,000,000.  In no event shall the Revolving Credit Maximum
Availability exceed $4,000,000.

provided, however, that if Borrower meets all of the Term-Out Requirements 

Page 60

on the Revolving Credit Facility Expiration Date, as of its fiscal year
ending December 31, 1996, the outstanding principal balance of the
Revolving Credit Note automatically shall term-out on the Revolving Credit
Facility Expiration Date without any further action by Borrower or Lender
and the outstanding principal balance of the Revolving Credit Note shall be
payable (and interest shall accrue and be payable thereon) as follows:

            (i)   Interest shall continue to accrue at the rates per annum
set forth in the Revolving Credit Note;  

            (ii)  The outstanding principal balance on the Revolving Credit
Facility Expiration Date shall be payable in sixty (60) equal consecutive
installments, commencing on May 15, 1997 and continuing to be due on the
same day of each succeeding month thereafter until the April 15, 2002, at
which time all unpaid principal and accrued interest shall be due and
payable in full;

            (iii) Accrued interest on the Revolving Credit Note shall be
due and payable on the same dates indicated in clause (ii) above on which
installments or other payments of principal are due hereunder.

            (iv)  A mandatory principal prepayment on the Revolving Credit
Note shall be made by Borrower, without penalty or premium, on May 15 of
each year, commencing on May 15, 1998, in an amount equal to twenty-five

December 31, 1997 minus one hundred percent (100%) of all Voluntary
Principal Prepayments. 

            (v)   A mandatory principal payment shall be made by Borrower
without penalty or premium on May 15, 1999 and each May 15 thereafter

       (D)  Borrower may prepay the Revolving Credit Note in whole or in
part in accordance with the terms and conditions of the Revolving Credit
Note.

       (E)  If the unpaid balance of the Revolving Credit Loans should
exceed the Revolving Credit Maximum Availability, or any other limitation
set forth in this Agreement, such Revolving Credit Loans shall nevertheless
constitute Obligations that are secured by the Collateral and entitled to
all benefits thereof.  In no event shall Borrower be authorized to request
a Revolving Credit Loan at any time that there exists a Default or an Event
of Default.

       (F)  Insofar as Borrower may request and Lender may be willing in
its sole and absolute discretion to make Revolving Credit Loans to Borrower
at a time when the unpaid balance of Revolving Credit Loans exceeds, or

Credit Maximum Availability (any such Loan or Loans being herein referred

Page 61

to individually as a "Revolving Credit Overadvance" and collectively as
"Revolving Credit Overadvances"), Lender shall enter such Revolving Credit 
Overadvances as debits in the Loan Account.  All Revolving Credit
Overadvances shall be repaid on demand and shall be evidenced by the
Revolving Credit Note.

be deemed to be made, in the following manner:  (i) Borrower may give
Lender notice of its intention to borrow, in which notice Borrower shall
specify the amount of the proposed borrowing, the proposed borrowing date
and that such borrowing is to be a Revolving Credit Loan; (ii) the becoming

irrevocably to be a request for a Revolving Credit Loan on the due date in
the amount then so due and (iii) pursuant to the terms of Borrower's FOCUS
account or similar account with Lender;

       (B)  Borrower hereby irrevocably authorizes Lender to disburse the
proceeds of each Revolving Credit Loan requested, or deemed to be
requested, pursuant to this Section 3.2 as follows:  (i) the proceeds of
each Revolving Credit Loan requested under Section 3.2(A)(i) shall be
disbursed by Lender in lawful money of the United States of America in
immediately available funds, in the case of the initial borrowing, in
accordance with the terms of the written disbursement letter from Borrower,
and in the case of each subsequent borrowing, by wire transfer to such bank
account as may be agreed upon by Borrower and Lender from time to time; and
(ii) the proceeds of each Revolving Credit Loan requested under Section
3.2(A)(ii) shall be disbursed by Lender by way of direct payment of the
relevant Obligation.

debits to the Revolving Credit Loan Account and shall also record in the
Revolving Credit Loan Account all payments made by Borrower on Revolving
Credit Loans and all proceeds of Collateral which are finally paid to

practice, all charges and expenses properly chargeable to Borrower
hereunder.

under any law which a court of competent jurisdiction shall, in a final
determination, deem applicable hereto.  In the event that such a court
determines that Lender has charged or received interest hereunder in excess
of the highest applicable rate, Lender shall promptly refund such excess
interest to Borrower and such rate shall automatically be reduced to the
maximum rate permitted by such law.

SECTION 4.  LETTERS OF CREDIT 

  4.1. Amounts, Terms and Issuance of Letters of Credit.

       If requested to do so by Borrower, Lender may, in its discretion,
issue one or more Letters of Credit for the account of Borrower; provided,
however that the sum of the aggregate outstanding principal balance of the
Line of Credit Loans and the Revolving Credit Loans at any one time plus
the aggregate stated amount of all Letters of Credit (other than
Cash-Secured Letters of Credit) then outstanding may not exceed the sum of
the Line of Credit Maximum Availability plus the Revolving Credit Maximum
Availability as then in effect and any amounts paid by Lender with respect
to any draw under any such Letter of Credit shall be deemed to be, at
Lender's election, a Line of Credit Loan or a Revolving Credit Loan and
shall bear interest and shall be repayable in accordance with the terms
hereof and of the Line of Credit Note or the Revolving Credit Note (as the
case may be) unless such amount is immediately reimbursed by Borrower on
demand therefor by Lender.  If requested to do so by Borrower, Lender may,
in its discretion, issue one or more Cash-Secured Letters of Credit for the
account of Borrower.

  4.2  Fees.

       Borrower shall pay to Lender for the issuance of each Letter of

  5.1. Termination.

       (A)  Upon at least thirty (30) days prior written notice to Lender,

Credit still issued and outstanding.

       (B)  Lender may terminate this Agreement at any time upon written
notice to Borrower upon the occurrence and during the continuation of an
Event of Default.

       (C)  All of the Obligations arising hereunder or evidenced by the
Notes shall be forthwith due and payable upon any termination of this
Agreement.  Except as otherwise expressly provided for in this Agreement or
the other Loan Documents, no termination or cancellation (regardless of 

Page 63

cause or procedure) of this Agreement or any of the other Loan Documents
shall in any way affect or impair the powers, obligations, duties, rights,
and liabilities of Borrower or Lender in any way relating to (i) any
transaction or event occurring prior to such termination or cancellation,
including without limitation any Letters of Credit which may be still
outstanding, or (ii) any of the undertakings, agreements, covenants,
warranties or representations of Borrower contained in this Agreement, or
any of the other Loan Documents.  All such undertakings, agreements,
covenants, warranties and representations shall survive such termination or
cancellation and Lender shall retain its Liens in the Collateral, and all
of its rights and remedies under this Agreement and the other Loan
Documents notwithstanding such termination or cancellation until Borrower
has paid the Obligations to Lender, in full, in immediately available
funds.

       (D)  It is understood that Borrower may elect to terminate this
Agreement in its entirety only; no section or lending facility may be
terminated singly.

  5.2. Costs, Fees and Expenses.

       (A) On the date of this Agreement, Borrower shall pay Lender a
non-refundable closing fee for the Revolving Credit Facility and the Line
of Credit Facility in the amount of $20,000, which closing fee shall be
deemed fully earned upon the parties' execution and delivery of this
Agreement.

       (B)  Costs, fees and expenses payable pursuant to this Agreement
shall be payable by Borrower, on demand, to Lender or to any other Person
designated by Lender in writing.
 
  5.3. Application of Payments and Collections.  Borrower irrevocably
waives the right to direct the application of any and all payments and
collections at any time or times hereafter received by Lender from or on
behalf of Borrower, and Borrower does hereby irrevocably agree that Lender
shall have the continuing exclusive right to apply and reapply any and all
such payments and collections received at any time or times hereafter by
Lender or its agent against the Obligations, in such manner as Lender may
deem advisable, notwithstanding any entry by Lender upon any of its books
and records.  If as the result of collections of Accounts as authorized by
this Agreement a credit balance exists in the Loan Account, such credit
balance shall not accrue interest in favor of Borrower, but shall be
available to Borrower at any time or times for so long as no Default or
Event of Default exists.  Lender may offset such credit balance upon or
after the occurrence of an Event of Default.

  5.4  Statements of Account.  Lender will account to Borrower monthly with
a statement of Loans, Letters of Credit, charges and payments made pursuant
to this Agreement, and such account rendered by Lender shall (absent
manifest error) be deemed final, binding and conclusive upon Borrower 
unless Lender is notified by Borrower in writing to the contrary within
thirty (30) days of the date each account was sent to Borrower at its
address set forth herein for notices.  Such notice shall only be deemed an 

Page 64

objection to those items specifically objected to therein. 

  5.5.All Loans and Obligations to Constitute One Obligation.  The Loans
(including without limitation any and all Line of Credit Overadvances and
Revolving Credit Overadvances) shall constitute one general obligation of
Borrower, and shall be secured by Lender's security interest in and Lien
upon all of the Collateral, and by all other security interests and Liens
heretofore, now or at any time or times hereafter granted by Borrower to
Lender.

  5.6  Capital Adequacy.  Without limiting any other provisions of this
Agreement, in the event that the Lender determines after the date hereof
that the introduction or change after the date of this Agreement of any
law, treaty, governmental (or quasi-governmental) rule, regulation,
guideline or order regarding capital adequacy, or any change therein or in
the interpretation or application thereof after the date of this Agreement,
or compliance by the Lender with any request or directive regarding capital
adequacy (whether or not having the force of law and whether or not failure
to comply therewith would be unlawful) from a central bank or governmental
authority or body having jurisdiction which is introduced or changed after
the date of this Agreement, does or shall have the effect of reducing the
rate of return on the Lender's capital as a consequence of its obligations
hereunder to a level below that which the Lender could have achieved but
for such law, treaty, rule, regulation, guideline or order or such change
or compliance (taking into consideration the Lender's policies with respect
to capital adequacy and assuming the full utilization of the Lender's
capital immediately before such adoption, change or compliance) by an
amount reasonably deemed by the Lender to be material, then the Lender
shall promptly after its determination of such occurrence notify the
Borrower thereof.  The Borrower agrees to pay to the Lender as an
additional fee from time to time, within ten (10) days after written notice
and demand by the Lender, such amount as the Lender certifies to be the
amount that will compensate it for such reduction in connection with its
obligations hereunder.  A certificate of the Lender claiming compensation
under this Section shall be conclusive in the absence of manifest error or
fraud and shall set forth the nature of the occurrence giving rise to such
compensation, the additional amount or amounts to be paid to it hereunder
and the method by which such amounts were determined.  In determining such
amount, the Lender may use reasonable averaging and attribution methods.

performance to Lender of the Obligations, Borrower hereby grants to Lender

       (E)  All of the real property, including, without limitation, all
easements, tenements, all buildings, structures and improvements now or
hereafter placed on the real property, and all fixtures now or hereafter
installed, located therein, and all appurtenances thereto, thereon or
therein described on Schedule 6.1(E) attached hereto; 
     
       (F)  All substitutions for and all replacements, products and cash

described in (A), (B), (C), (D), (E) or (F) above.

  6.2. Representations, Warranties and Covenants -- Collateral.  To induce
Lender to enter into this Agreement, Borrower represents, warrants, and
covenants to Lender:

       (A)  The Collateral is now, and will be and so long as the
Obligations are outstanding, owned solely by Borrower.  No other Person has
or will have any right, title, interest, claim, or Lien therein, thereon or
thereto other than a Permitted Lien.

       (B)  The Liens granted to Lender shall be first and prior on the
Collateral and as to the Accounts and proceeds, including insurance
proceeds, resulting from the sale, disposition, or loss thereof.  Except
for the filing of appropriate financing statements, no further action need
be taken to perfect the Liens granted to Lender, other than the filing of
continuation statements under the Code or other applicable law at
appropriate times and continued possession by Lender of that portion of the
Collateral constituting instruments or documents.

       (C)  Borrower shall pay and discharge when due or within any period
when payment may be made without penalty all taxes, levies, and other
charges upon said Collateral and upon the goods evidenced by any documents
constituting Collateral and shall defend Lender against and save it
harmless from all claims of any Person with respect to the Collateral
except that Borrower's failure to pay any such taxes shall not be deemed an
Event of Default so long as Borrower's failure to pay any such taxes has
not given rise to a Lien other than a Permitted Lien.  This indemnity shall
include reasonable attorneys' fees and legal expenses.

  6.3. Financing Statements.  Borrower agrees to execute the financing
statements provided for by the Code together with any and all other
instruments, assignments or documents and shall take such other action as
may be required to perfect or to continue the perfection of Lender's 

Page 66

security interest in the Collateral.  Unless prohibited by applicable law,
Borrower hereby authorizes Lender to execute and file any such financing
statement on Borrower's behalf.  The parties agree that a carbon,
photographic or other reproduction of this Agreement shall be sufficient as
a financing statement and may be filed in any appropriate office in lieu
thereof.

  6.4. Cash Collateral Account.  The Obligations also shall be secured by
the Cash Collateral Account pursuant to the Cash Collateral Account
Agreement.

  6.5  Additional Collateral  Prior to Lender making any Revolving Credit
Loan or Line of Credit Loan to Borrower to finance Borrower's acquisition
of any real estate which is not described on Schedule 6.1(E) hereof, 
Borrower shall (i) execute and deliver any and all other documents,
instruments and agreements as Lender may from time to time request in order
to perfect and maintain the perfection of Lender's Lien in such real
estate, (ii) deliver or cause to be delivered to Lender, at Borrower's
expense, a mortgagee title insurance policy issued by a title insurance
company acceptable to Lender, and insuring Lender's Lien in such real
estate, which policy shall be in form and substance satisfactory to Lender
and shall insure a valid first priority Lien in favor of Lender in such
real estate (subject only to such exceptions as may be acceptable to Lender
and its counsel) and (iii) deliver, or cause to be delivered such opinion
letters, appraisals, surveys, record examination reports and environmental
audit reports as Lender may request, all at Borrower's expense.
 
SECTION 7.  REPRESENTATIONS AND WARRANTIES

  7.1. General Representations and Warranties.  To induce Lender to enter
into this Agreement and to make advances hereunder, Borrower warrants,
represents and covenants to Lender that:

       (A)  Organization and Qualification.  Borrower is a corporation duly
organized, validly existing and in good standing under the laws of the
State of Delaware.  Borrower has duly qualified and is authorized to do
business and is in good standing as a foreign corporation in each state or
jurisdiction listed on Schedule 7.1(A) attached hereto and made a part
hereof and in all other states and jurisdictions where the character of its
Properties or the nature of its activities make such qualification
necessary and in which the failure to be so qualified would have a material
adverse affect on Borrower's business operations or financial condition.

       (B)  Corporate Names.  During the preceding five (5) years, Borrower
has not been known as or used any corporate, fictitious or trade names
except as disclosed on Schedule 7.1(B) attached hereto and made a part
hereof.  Except as set forth on Schedule 7.1(B), Borrower has not, during
the preceding five (5) years, been the surviving corporation of a merger or
consolidation or acquired all or substantially all of the assets of any
Person.

       (C)  Corporate Power and Authority.  Borrower has the right and
power and is duly authorized and empowered to enter into, execute, deliver
and perform this Agreement and each of the other Loan Documents to which it 

Page 67

is a party.  The execution, delivery and performance of this Agreement and
each of the other Loan Documents have been duly authorized by all necessary
corporate action and do not and will not (i) require any consent or
approval of the shareholders of Borrower; (ii) contravene Borrower's
charter, articles of incorporation or by-laws; (iii) violate, or cause
Borrower to be in default under, any provision of any law, rule,
regulation, order, writ, judgment, injunction, decree, determination or
award in effect having applicability to Borrower; (iv) result in a breach
of or constitute a default under any material indenture or loan or credit
agreement or any other agreement, lease or instrument to which Borrower is
a party or by which it or its Properties may be bound or affected; or (v)
result in, or require, the creation or imposition of any Lien (other than
Permitted Liens) upon or with respect to any of the Properties now owned or
hereafter acquired by Borrower.

       (D)  Legally Enforceable Agreement.  This Agreement is, and each of
the other Loan Documents when delivered under this Agreement will be, a
legal, valid and binding obligation of Borrower enforceable against it in
accordance with their respective terms, except to the extent that such
enforcement may be limited by applicable bankruptcy, insolvency and other
similar laws affecting creditors' rights generally or by principles of
equity pertaining to the availability of equitable remedies.

       (E)  Use of Proceeds.  Borrower's uses of the proceeds of any
advances made by Lender to Borrower pursuant to this Agreement are, and
will continue to be, legal and proper corporate uses, duly authorized by
its Board of Directors, and such uses are consistent with all applicable
laws and statutes, as in effect as of the date hereof.

       (F)  Margin Stock.  Borrower is not engaged principally, or as one
of its important activities, in the business of purchasing or carrying
"margin stock" (within the meaning of Regulation G or U of the Board of
Governors of the Federal Reserve System), and no part of the proceeds of
any Loans to Borrower will be used to purchase or carry any margin stock or
to extend credit to others for the purpose of purchasing or carrying any
margin stock or be used for any purpose which violates or is inconsistent
with the provisions of Regulation G, T, U or X of said Board of Governors.

       (G)  Governmental Consents.  Borrower has, and is in good standing
with respect to, all governmental consents, approvals, authorizations,
permits, certificates, inspections, and franchises necessary to continue to
conduct its business as heretofore or proposed to be conducted by it and to
own or lease and operate its Properties as now owned or leased by it.

       (H)  Solvent Financial Condition.  Borrower is now and, after giving
effect to the initial Loans to be made hereunder, at all times will be,
Solvent.

       (I)  Litigation.  Except as set forth on Schedule 7.1(I) attached
hereto and made a part hereof, there are no actions, suits, proceedings or
investigations pending, or to the knowledge of Borrower, threatened,
against or affecting Borrower, or the business, operations, Properties,
prospects, profits or condition of Borrower, in any court or before any
governmental authority or arbitration board or tribunal, and no action, 

Page 68

suit, proceeding or investigation shown on Schedule 7.1(I) involves the
possibility of materially and adversely affecting the Properties, business,
profits or condition (financial or otherwise) of Borrower or the ability of
Borrower to perform this Agreement.  Borrower is not in default with
respect to any order, writ, injunction, judgment, decree or rule of any
court, governmental authority or arbitration board or tribunal which might
materially and adversely affect the Properties, business, profits or
condition (financial or otherwise) of Borrower.

       (J)  Title to Properties.  Borrower has good, indefeasible and
marketable title to and fee simple ownership of, or valid and subsisting
leasehold interests in, all of its real Property, and good title to all of
its other Property, including, without limitation, the Accounts, Inventory
and Equipment, in each case, free and clear of all Liens except Permitted
Liens.

       (K)  Financial Statements.  The balance sheet of Borrower as of
September 30, 1995, and the related statements of income, changes in
stockholder's equity, and changes in financial position for the periods
ended on such dates, have been prepared in accordance with GAAP (except for
changes in application in which Borrower's independent certified public
accountants concur), and present fairly the financial position of Borrower
at such dates and the results of Borrower's operations for such periods. 
Since September 30, 1995, there has been no material adverse change in the
condition, financial or otherwise, of Borrower, except changes in the
ordinary course of business, which individually or in the aggregate has
been materially adverse.

       (L)  Full Disclosure.  The financial statements referred to in
Section 7.1(K) above, do not, nor does this Agreement or any other written
statement of Borrower to Lender (including, without limitation, Borrower's
filings, if any, with the Securities and Exchange Commission), contain any
untrue statement of a material fact or omit a material fact necessary to
make the statements contained therein or herein not misleading.  There is
no fact which Borrower has failed to disclose to Lender in writing which
materially affects adversely or, so far as Borrower can now foresee, will
materially affect adversely the Properties, business, profits, or condition
(financial or otherwise) of Borrower or the ability of Borrower to perform
this Agreement.

       (M)  Pension Plans.  Except as disclosed on Schedule 7.1(M) attached
hereto and made a part hereof, Borrower has no Plan.  Borrower has not
received any notice to the effect that it is not in full compliance with
any of the requirements of ERISA and the regulations promulgated
thereunder.  No fact or situation, including, but not limited to, any
Reportable Event, or Prohibited Transaction exists in connection with any
Plan which would create a liability of the Borrower.  Borrower does not
have any withdrawal liability in connection with a Multiemployer Plan.

       (N)  Taxes.  Borrower has filed all federal, state and local tax
returns and other reports it is required by law to file and has paid, or
made provision for the payment of, all taxes, assessments, fees and other
governmental charges that are due and payable, except such taxes, if any,
as are being actively contested in good faith and as to which adequate 

Page 69

reserves have been provided.  The provision for taxes on the books of
Borrower is adequate for all years not closed by applicable statutes, and
for its current fiscal year.

       (O)  Compliance With Laws.  Except with respect to Environmental
Laws, which are covered in Section 7.1(P) below, Borrower has duly complied
with, and its Properties, business operations and leaseholds are in
compliance with, in all material respects, the provisions of all federal,
state and local laws, rules and regulations applicable to Borrower, its
Properties or the conduct of its business, including, without limitation,
OSHA and all Environmental Laws, and there have been no citations, notices
or orders of noncompliance issued to Borrower under any such law, rule or
regulation.

       (P)  Environmental Laws.

            (i)   Borrower is in compliance with all Environmental Laws,
with the exceptions of instances that will not in the aggregate result in
any material liability on the part of Borrower.
            (ii)  Except as described in Schedule 7.1(P), Borrower has not
received notice of any failure to comply with, nor has any such notice been
issued that has not been satisfied so as to bring any property of Borrower
into compliance with, all Environmental Laws.  All licenses, permits or
registrations (or any extensions thereof) required under any Environmental
Laws for the business of Borrower as proposed to be conducted have been
obtained, and Borrower is in compliance therewith.  Borrower is in
compliance with, and is not in breach of or default under applicable order
of any Governmental Authority and no event has occurred and is continuing
that, with the passage of time or the giving of notice or both, would
constitute compliance, breach or default thereunder.
            (iii) Except as described in Schedule 7.1(P), (a) no Hazardous
Substance has been Released (and no oral or written notification of such
Release has been filed) or is present (whether or not in a reportable or
threshold planning quantity) at, on or under any property owned or leased
by Borrower during the period of Borrower's ownership or lease, under
conditions that required substantial remedial action under applicable
Environmental Laws, and (b) no property now or previously owned or leased
by Borrower has, directly or indirectly, transported or arranged for the
transportation of any Hazardous Substances to any site listed, or proposed
for listing, on the National Priorities List promulgated pursuant to
CERCLA, on CERCLIS (as defined in CERCLA) or on any similar Federal, state
or foreign list of sites requiring investigation or cleanup.  Borrower is
not aware of any event, condition or circumstances involving environmental
pollution or contamination, or employee safety or health relating to the
use or handling of, or exposure to, Hazardous Substances, that could
reasonably be expected to materially adversely effect the operations,
Properties, business, prospects, profits or financial condition of
Borrower.  Borrower and Lender acknowledge and agree that certain Inventory
consists of radioactive isotopes, which shall be handled in compliance with
all Environmental Laws.

Page 70

       (Q)  No Defaults.  No event has occurred and no condition exists
which would, upon the execution and delivery of this Agreement or
Borrower's performance hereunder, constitute a Default or an Event of
Default.  Borrower is not in default, and no event has occurred and no
condition exists which constitutes, or which with the passage of time or
the giving of notice or both would constitute, a default in the payment of
any Indebtedness of Borrower to any Person for Money Borrowed.

       (R)  Brokers.  There are no claims for brokerage commissions,
finder's fees or investment banking fees in connection with the
transactions contemplated by this Agreement.

       (S)  Investment Company Act.  Borrower is not an "investment
company" or a company "controlled" by an "investment company", within the
meaning of the Investment Company Act of 1940, as amended.

  7.2. Reaffirmation  Each request for a Loan made by Borrower pursuant to
this Agreement or any of the other Loan Documents shall constitute (i) an
automatic representation and warranty by Borrower to Lender that there does
not then exist any Default or Event of Default and (ii) a reaffirmation as
of the date of said request of all of the representations and warranties of
Borrower contained in this Agreement and the other Loan Documents except as
to those changes otherwise consented to by Lender or contemplated herein.

  7.3. Survival of Representations and Warranties.  Borrower covenants,
warrants and represents to Lender that all representations and warranties
of Borrower contained in this Agreement or any of the other Loan Documents
shall be true at the time of Borrower's execution of this Agreement and the
other Loan Documents in all material respects, and shall survive the
execution, delivery and acceptance thereof by Lender and the parties
thereto and the closing of the transactions described therein or related
thereto.

SECTION 8.  COVENANTS AND CONTINUING AGREEMENTS

  8.1. Affirmative Covenants.  During the term of this Agreement, and
thereafter for so long as there are any Obligations to Lender, Borrower
covenants that, unless otherwise consented to by Lender in writing, it

       (A)  Taxes and Liens.  Pay and discharge all taxes, assessments and
governmental charges upon it, its income and Properties as and when such
taxes, assessments and charges are due and payable, or within any period
prior to the imposition of penalties, except and to the extent only that
such taxes, assessments and charges are being actively contested in good
faith and by appropriate proceedings, Borrower maintains adequate reserves
on its books therefor and the nonpayment of such taxes, assessments and
charges does not result in a Lien upon any Properties or Borrower other
than a Permitted Lien.  Borrower shall also pay and discharge any lawful
claims which, if unpaid, might become a Lien against any of Borrower's
Properties except for Permitted Liens.

Page 71

       (B)  Tax Returns.  File all federal, state and local tax returns and
other reports Borrower is required by law to file, and maintain adequate
reserves for the payment of all taxes, assessments, governmental charges,
and levies imposed upon it, its income, or its profits, or upon any
Property belonging to it.

       (C)  Business and Existence.  Preserve and maintain its separate
corporate existence and all rights, privileges, and franchises in
connection therewith, and maintain its qualification and good standing in
all states in which such qualification is necessary and in which the
failure to so qualify would materially and adversely affect its business
operations or financial condition.

       (D)  Maintain Properties.  Maintain its Properties in good condition
and make all necessary renewals, repairs, replacements, additions and
improvements thereto to the extent permitted hereby and except as caused by
ordinary wear and tear, obsolescence, loss or damage.

       (E)  Compliance with Laws.  Comply with all laws, ordinances,
governmental rules and regulations, in all material respects, to which it
is subject, and obtain and keep in force any and all governmental licenses,
permits, franchises, or other governmental authorizations necessary to the
ownership of its Properties or to the conduct of its business.

       (F)  ERISA Compliance.  (i) At all times make prompt payment of
contributions required to meet the minimum funding standards set forth in
ERISA with respect to each Plan; (ii) promptly after the filing thereof,

to ERISA in connection with each Plan and any other employee benefit plan
of it and its Affiliates; (iii) notify Lender as soon as practicable of any
Reportable Event and of any additional act or condition arising in
connection with any Plan which Borrower believes might constitute grounds
for the termination thereof by the Pension Benefit Guaranty Corporation or
for the appointment by the appropriate United States district court of a
trustee to administer the Plan; and (iv) furnish to Lender, promptly upon
Lender's request therefor, such additional information concerning any Plan
or any other such employee benefit plan as may be reasonably requested.

       (G)  Business Records.  Keep adequate records and books of account

normal business hours, to visit and inspect the Properties of Borrower,
inspect and make extracts from its books and records, and discuss with its
officers, its employees and its independent accountants, Borrower's
business, assets, liabilities, financial condition, business prospects and
results of operations.  Provided there shall be no ongoing and uncured
Event of Default, (i) Lender shall give Borrower at least one Business
Day's notice of any such inspection and (ii) Borrower may impose reasonable
limitations on Lender's inspection of Borrower's business operations

the close of each fiscal year of Borrower audited financial statements

accountants) of Borrower as of the end of such year prepared in accordance
with GAAP applied on a consistent basis, unless Borrower's certified public
accountants concur in any change therein and such change is disclosed to
Lender and is consistent with GAAP, certified by a firm of independent
certified public accountants of recognized standing selected by Borrower
but acceptable to Lender, which acceptance shall not be unreasonably
withheld;

       (ii)   as soon as possible, but not later than forty-five (45) days

accounts payable ledgers, and bank statements.

  Concurrently with the delivery of the financial statements described in

appropriate proceedings; and
     
            (iii)  promptly notify Lender of any of the following:
     
            (a)    any Environmental Claim that Borrower receives,

                   Hazardous Substance contained on any property owned or 
                   leased by Borrower;

                   requirement of any Environmental Law by Borrower.
               
       Borrower agrees to indemnify Lender and its directors, officers,
employees, agents and Affiliates (each such person being called an
"Indemnitee") against, and hold each Indemnitee harmless from, any claims,
demands, penalties, fines, liabilities, settlements, damages, costs and
expenses (including attorneys' fees, charges and disbursements) of whatever 

Page 74

kind or nature arising out of , or in any way relating to, the violation
of, noncompliance with or liability under any Environmental Laws applicable
to the operations of Borrower or to the Collateral, or any orders, 
requirements or demands of Governmental Authorities related thereto,
including, without limitation, attorneys' and consultants' fees,
investigation and laboratory fees, response costs, court costs and
litigation expenses, except to the extent that any of the foregoing are
found by a final and nonappealable decision of a court of competent
jurisdiction to have resulted from the gross negligence or willful
misconduct of the Indemnitee seeking indemnification therefor. The
obligations of Borrower under this Section shall survive the termination of
this Agreement indefinitely.
     
       (L)  Further Assurances.  At Lender's request, promptly execute or
cause to be executed and deliver to Lender any and all documents,
instruments and agreements deemed reasonably necessary by Lender to give
effect to or carry out the terms or intent of this Agreement or any of the
other Loan Documents.  Without limiting the generality of the foregoing, if
any of the Accounts, the face value of which exceeds $5,000, arises out of
a contract with the United States of America, or any department, agency,
subdivision or instrumentality thereof, Borrower shall promptly notify
Lender thereof in writing and shall execute any instruments and take any
other action required or requested by Lender to comply with the provisions
of the Federal Assignment of Claims Act.

       (M)  Insurance.  Borrower will maintain, with financially sound and
reputable insurers, insurance with respect to its Properties and business
and against such casualties, liabilities and contingencies of such type
(including, without limitation, public liability, product liability,
larceny, embezzlement or other criminal misappropriation) and in such
amounts as is customary for similarly situated Persons engaged in
businesses similar to those of Borrower.

       (N)  Primary Banking Relationships.  To the maximum extent permitted
by applicable law, Borrower shall maintain its primary banking
relationships with Lender.

       (P)  Title Policy Endorsement.     Within thirty (30) days after the

  8.2. Negative Covenants.  During the term of this Agreement, and
thereafter for so long as there are any Obligations to Lender, Borrower
covenants that, unless Lender has first consented thereto in writing, it
will not:

any Person.

Page 75

to its employees so long as the aggregate outstanding principal balance
thereof does not exceed $150,000 at any one time.

       (C)  Affiliate Transactions.  Enter into, or be a party to any
transaction with any Affiliate or stockholder, except in the ordinary
course of and pursuant to the reasonable requirements of Borrower's
business and upon fair and reasonable terms which are fully disclosed to
Lender and are no less favorable to Borrower than would obtain in a
comparable arm's length transaction with a Person not an Affiliate or
stockholder of Borrower.

       (D)  Guaranties.  Guarantee, assume, endorse or otherwise, in any
way, become directly or contingently liable with respect to the
Indebtedness of any Person except by endorsement of instruments or items of

any of its Property, income or profits, whether now owned or hereafter
acquired, except:  (i) Liens at any time granted in favor of Lender; (ii)
Liens for taxes (excluding any Lien imposed pursuant to any of the

Page 81

  10.2.     Acceleration of the Obligations.  Without in any way limiting
the right of Lender to demand payment of any portion of the Obligations
payable on demand in accordance with this Agreement, upon and after the
occurrence of an Event of Default as above provided, all or any portion of
the Obligations due or to become due from Borrower to Lender, whether under
this Agreement, or any of the other Loan Documents or otherwise, shall, at
the option of Lender and without notice or demand by Lender, become at once
due and payable and Borrower shall forthwith pay to Lender, in addition to
any and all sums and charges due, the entire principal of and interest
accrued on the Obligations.

  10.3.     Remedies.  Upon the occurrence of an Event of Default and

       (A)  By written notice to the Borrower, terminate the Lender's
remaining commitment hereunder to make any further loans to Borrower
whereupon any such commitment shall terminate immediately.

       (B)  All of the rights and remedies of a secured party under the
Code or under other applicable law, and all other legal and equitable
rights to which Lender may be entitled, all of which rights and remedies
shall be cumulative, and none of which shall be exclusive, and shall be in
addition to any other rights or remedies contained in this Agreement or any
of the other Loan Documents.

       (C)  The right to take immediate possession of the Collateral, and

premises be the Property of Borrower, Borrower agrees not to charge Lender
for storage thereof).

       (D)  The right to sell or otherwise dispose of all or any Inventory
in its then condition, or after any further manufacturing or processing
thereof, at public or private sale or sales, with such notice as may be
required by law, in lots or in bulk, for cash or in credit, all as Lender
in its sole discretion, may deem advisable.  Borrower agrees that ten (10)
days' prior written notice to Borrower of any public or private sale or
other disposition of such Collateral shall be reasonable notice thereof and
such sale shall be at such location as Lender may designate in said notice. 
Lender shall have the right to conduct such sales on Borrower's premises,
without charge therefor, and such sales may be adjourned from time to time
in accordance with applicable law.  Lender shall have the right to sell,
lease or otherwise dispose of such Collateral, or any part thereof, for
cash, credit or any combination thereof, and Lender may purchase all or any
part of such collateral at public or, if permitted by applicable law,

advertising for sale and selling any Collateral and Borrower's rights under
all licenses and all franchise agreements shall inure to Lender's benefit.

Lender for collection and for acquisition, completion, protection, removal,
storage, sale and delivery of the Collateral; secondly, to interest due
upon any of the Obligations; and thirdly, to the principal of the
Obligations.  If any deficiency shall arise, Borrower and the Guarantor
shall remain liable to Lender therefor; and any surplus shall be paid to
Borrower.

  10.4.     Remedies Cumulative; No Waiver.  All covenants, conditions,
provisions, warranties, guaranties, indemnities, and other undertakings of
Borrower contained in this Agreement and the other Loan Documents, or in
any document referred to herein or contained in any agreement supplementary
hereto or in any schedule given to Lender or contained in any other
agreement between Lender and Borrower, heretofore, concurrently, or
hereafter entered into, shall be deemed cumulative to and not in derogation
or substitution of any of the terms, covenants, conditions, or agreements
of Borrower herein contained.  The failure or delay of Lender to exercise
or enforce any rights, Liens, powers, or remedies hereunder or under any of
the aforesaid agreements or other documents or security or Collateral shall
not operate as a waiver of such Liens, rights, powers and remedies, but all
such Liens, rights, powers, and remedies shall continue in full force and
effect until all Loans and all other Obligations owing or to become owing
from Borrower to Lender shall have been fully satisfied, and all Liens,
rights, powers, and remedies herein provided for are cumulative and none
are exclusive.

Lender harmless from and against any liability, loss, damage, suit, action
or proceeding ever suffered or incurred by Lender as the result of
Borrower's failure to observe, perform or discharge Borrower's duties
hereunder.  Without limiting the generality of the foregoing, this
indemnity shall extend to any claims asserted against Lender by any Person
under any Environmental Laws or similar laws by reason of Borrower's or any
other Person's failure to comply with laws applicable to solid or hazardous
waste materials or other toxic substances.

  11.3.     Modification of Agreement; Sale of Interest.  This Agreement
may not be modified, altered or amended, except by an agreement in writing
signed by Borrower and Lender.  Borrower may not sell, assign or transfer
any interest in this Agreement or any of the other Loan Documents, or any
portion thereof, including, without limitation, Borrower's rights, title,
interests, remedies, powers, and duties hereunder or thereunder.  Borrower
hereby consents to Lender's participation, sale, assignment, transfer or
other disposition, at any time or times hereafter, of this Agreement and
any of the other Loan Documents, or of any portion hereof or thereof,
including, without limitation, Lender's rights, title, interests, remedies,
powers, and duties hereunder or thereunder.

  11.4.     Reimbursement of Expenses.  If, at any time or times prior or
subsequent to the date hereof, regardless of whether or not an Event of

concluded, Lender employs counsel for advice or other representation, or
incurs legal expenses or other costs or out-of-pocket expenses in
connection with:  (A) the negotiation and preparation of this Agreement or 

Page 84

any of the other Loan Documents, any amendment of or modification of this
Agreement or any of the other Loan Documents; or (B) the administration of
this Agreement or any of the other Loan Documents and the transactions
contemplated hereby and thereby; (C) any litigation, contest, dispute,
suit, proceeding or action (whether instituted by Lender, Borrower or any
other Person) in any way relating to the Collateral, this Agreement or any
of the other Loan Documents or Borrower's affairs; (D) any attempt to
enforce any rights of Lender against Borrower or any other Person which may
be obligated to Lender by virtue of this Agreement or any of the other Loan
Documents, including, without limitation, the Account Debtors; or (E) any
attempt to inspect, verify, protect, preserve, restore, collect, sell,
liquidate or otherwise dispose of or realize upon the Collateral; then, in
any such event, the attorneys' fees arising from such services and all
expenses, costs, charges and other fees of such counsel or of Lender or
relating to any of the events or actions described in this Section shall be
payable, on demand, by Borrower to Lender, and shall be additional

issuance or recording of any of the other Loan Documents, or the creation
of any of the Obligations hereunder, by reason of any existing or hereafter
enacted federal or state statute, Borrower will pay all such taxes,
including, but not limited to, any interest and penalties thereon, and will
indemnify and hold Lender harmless from and against liability in connection
therewith.

  11.5.     Indulgences Not Waivers.  Lender's failure, at any time or
times hereafter, to require strict performance by Borrower of any provision
of this Agreement shall not waive, affect or diminish any right of Lender
thereafter to demand strict compliance and performance therewith.  Any
suspension or waiver by Lender of an Event of Default by Borrower under
this Agreement or any of the other Loan Documents shall not suspend, waive
or affect any other Event of Default by Borrower under this Agreement or
any of the other Loan Documents, whether the same is prior or subsequent
thereto and whether of the same or of a different type.  None of the
undertakings, agreements, warranties, covenants and representations of
Borrower contained in this Agreement or any of the other Loan Documents and
no Event of Default by Borrower under this Agreement or any of the other
Loan Documents shall be deemed to have been suspended or waived by Lender,
unless such suspension or waiver is by an instrument in writing specifying
such suspension or waiver and is signed by a duly authorized representative
of Lender and directed to Borrower.

  11.6.     Severability.  Wherever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Agreement shall be
prohibited by or invalid under applicable law, such provision shall be 

Page 85

ineffective only to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of
this Agreement.

and assigns of Borrower and Lender.  This provision, however, shall not be
deemed to modify Section 11.3 hereof.

other Loan Documents are hereby made cumulative with the provisions of this
Agreement.  Except as otherwise provided in any of the other Loan Documents
by specific reference to the applicable provision of this Agreement, if any
provision contained in this Agreement is in direct conflict with, or
inconsistent with, any provision in any of the other Loan Documents, the
provision contained in this Agreement shall govern and control.

  11.9.     Execution in Counterparts.  This Agreement may be executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed
to be an original and all of which counterparts taken together shall
constitute but one and the same instrument.

  11.10.    Notice.  Except as otherwise provided herein, all notices,
requests and demands to or upon a party hereto to be effective shall be in
writing (and, if sent by mail, shall be sent by certified or registered

or to such other address as each party may designate for itself by like
notice given in accordance with this Section 11.10; provided, however, that
any notice, request or demand to or upon Lender pursuant to Sections 2.2 or
3.2 shall not be effective until received by Lender.

  11.11.    Lender's Consent.  Whenever Lender's consent is required to be
obtained under this Agreement or any of the other Loan Documents as a
condition to any action, inaction, condition or event, Lender shall be
authorized to give or withhold such consent in its sole and absolute
discretion and to condition its consent upon the giving of additional
collateral security for the Obligations, the payment of money or any other
matter.

  11.12.    Demand Obligations.  Nothing in this Agreement shall affect or
abrogate the demand nature of any portion of the Obligations expressly made
payable on demand by this Agreement or by any instrument evidencing or
securing same, and the occurrence of an Event of Default shall not be a
prerequisite for Lender's requiring payment of such Obligations.

  11.13.    Time of Essence.  Time is of the essence of this Agreement and
the other Loan Documents.

  11.14.    Entire Agreement.  This Agreement and the other Loan Documents,
together with all other instruments, agreements and certificates executed
by the parties in connection therewith or with reference thereto, embody
the entire understanding and agreement between the parties hereto and
thereto with respect to the subject matter hereof and thereof and supersede
the Prior Loan Agreements and all other prior agreements, understandings
and inducements, whether express or implied, oral or written.  Nothing
contained herein is intended (or shall be construed) to be a novation of
any indebtedness evidenced by the Prior Loan Agreements or to affect or
modify the perfection or priority of Lender's security interests in,
security titles to or other liens on any Collateral.

  11.15.    Reliance on Telecopies.  Each of Borrower and Lender may
transmit to the other any and all notices, reports or other communications
required or permitted to be given under this Agreement by way of telecopy
to such other party at its telecopy number shown in Section 11.10 above (or
at such other telecopy number as such other party may designate by written
notice given pursuant to Section 11.10 above), and in that case the party
to whom any such telecopy is transmitted shall be entitled to rely on any
such telecopied notice, report or other communication as an original
thereof unless and until such party receives an executed original thereof.

  11.16.    GOVERNING LAW; CONSENT TO FORUM.  THIS AGREEMENT HAS BEEN
NEGOTIATED, EXECUTED AND DELIVERED AT AND SHALL BE DEEMED TO HAVE BEEN MADE
IN ATLANTA, GEORGIA.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF GEORGIA; PROVIDED, HOWEVER, THAT
IF ANY OF THE COLLATERAL SHALL BE LOCATED IN ANY JURISDICTION OTHER THAN
GEORGIA, THE LAWS OF SUCH JURISDICTION SHALL GOVERN THE METHOD, MANNER AND
PROCEDURE FOR FORECLOSURE OF LENDER'S LIEN UPON SUCH COLLATERAL AND THE 

Page 84

ENFORCEMENT OF LENDER'S OTHER REMEDIES IN RESPECT OF SUCH COLLATERAL TO THE
EXTENT THAT THE LAWS OF SUCH JURISDICTION ARE DIFFERENT FROM OR
INCONSISTENT WITH THE LAWS OF GEORGIA.  AS PART OF THE CONSIDERATION FOR
NEW VALUE THIS DAY RECEIVED, BORROWER HEREBY CONSENTS TO THE JURISDICTION
OF ANY STATE OR FEDERAL COURT LOCATED WITHIN FULTON COUNTY OF THE STATE OF
GEORGIA AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR
REGISTERED MAIL DIRECTED TO BORROWER AT THE ADDRESS STATED IN SECTION 11.10
HEREOF AND SERVICE SO MADE SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL
RECEIPT THEREOF.  BORROWER WAIVES ANY OBJECTION TO JURISDICTION AND VENUE
OF ANY ACTION INSTITUTED AGAINST IT AS PROVIDED HEREIN AND AGREES NOT TO
ASSERT ANY DEFENSE BASED ON LACK OF JURISDICTION OR VENUE.

  11.17.    WAIVERS BY BORROWER.  EXCEPT AS OTHERWISE PROVIDED FOR IN THIS
AGREEMENT, BORROWER WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
LAW (i) THE RIGHT TO TRIAL BY JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY
ACTION, SUIT, PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR
RELATED TO ANY OF THE LOAN DOCUMENTS, THE OBLIGATIONS OR THE COLLATERAL;
(ii) PRESENTMENT, DEMAND AND PROTEST AND NOTICE OF PRESENTMENT, PROTEST,
DEFAULT, NON PAYMENT, MATURITY, RELEASE, COMPROMISE, SETTLEMENT, EXTENSION
OR RENEWAL OF ANY OR ALL COMMERCIAL PAPER, ACCOUNTS, CONTRACT RIGHTS,
DOCUMENTS, INSTRUMENTS, CHATTEL PAPER AND GUARANTIES AT ANY TIME HELD BY
LENDER ON WHICH BORROWER MAY IN ANY WAY BE LIABLE AND HEREBY RATIFIES AND
CONFIRMS WHATEVER LENDER MAY DO IN THIS REGARD; (iii) NOTICE PRIOR TO
TAKING POSSESSION OR CONTROL OF THE COLLATERAL OR ANY BOND OR SECURITY
WHICH MIGHT BE REQUIRED BY ANY COURT PRIOR TO ALLOWING LENDER TO EXERCISE
ANY OF LENDER'S REMEDIES, INCLUDING THE ISSUANCE OF AN IMMEDIATE WRIT OF 


             [REMAINDER OF PAGE INTENTIONALLY LEFT BLANK]

POSSESSION; (iv) THE BENEFIT OF ALL VALUATION, APPRAISEMENT AND EXEMPTION
LAWS; AND (v) ANY RIGHT BORROWER MAY HAVE UPON PAYMENT IN FULL OF THE
OBLIGATIONS TO REQUIRE LENDER TO TERMINATE ITS SECURITY INTEREST IN THE
COLLATERAL OR IN ANY OTHER PROPERTY OF BORROWER UNTIL TERMINATION OF THIS
AGREEMENT IN ACCORDANCE WITH ITS TERMS AND THE EXECUTION BY BORROWER, AND
BY ANY PERSON WHOSE LOANS TO BORROWER ARE USED IN WHOLE OR IN PART TO
SATISFY THE OBLIGATIONS, OF AN AGREEMENT INDEMNIFYING LENDER FROM ANY LOSS
OR DAMAGE LENDER MAY INCUR AS THE RESULT OF DISHONORED CHECKS OR OTHER
ITEMS OF PAYMENT RECEIVED BY LENDER FROM BORROWER OR ANY ACCOUNT DEBTOR AND
APPLIED TO THE OBLIGATIONS.

     IN WITNESS WHEREOF, this Agreement has been duly executed in Atlanta,
Georgia, on the day and year specified at the beginning hereof.
