Granting of a General Line of Credit


Dear Mr. Kempf,


We are pleased to again grant you a line of credit.


Amount:                                     DM 5,000,000.00
                                            (in words: DM five million)
                                            to be used either as:


                                            1. Current account credit on
                                               account no. 4473213


                                            2. Euroloan on several accounts


Intended Use:                               The loan is for commercial purposes.

Duration:                                   Until 31 August 2000

Terms:                                      Ref. 1.: 6.50% p.a. on the amount
                                            utilised within the scope of the
                                            line of credit.

                                            This interest rate shall be valid
                                            until further notice. The bank has
                                            the right to increase the interest
                                            rate when the cost of refinancing on
                                            the money market has increased. In
                                            the event of a decrease of the cost
                                            of refinancing, the bank will also
                                            decrease the interest rate.
<PAGE>

                           Accounts shall be balanced at the end of each
                           quarter.

                           Ref. 2.: We request you co-ordinate the amount and
                           the interest rate of the individual Euroloan tranches
                           from time to time.

Collateral:                This current account credit is provided to you
                           without the provision of collateral. However, rights
                           to collateral which exist or arise according to the
                           General Terms and Conditions remain unaffected.

Equal Treatment Clause:    Other banks providing loans shall not be put in a
                           better position than us regarding collateral (for
                           similar loans) and information and this agreement
                           with the other banks is also in writing. We have the
                           right at all times to inspect the loan
                           agreements/contracts of the other banks.

Additional Agreement:      As agreed upon with you, you will take us into
                           consideration in a reasonable manner in the
                           allocation of business.

Insofar as you want to borrow Euro funds against your line of credit, we
herewith confirm to you, also on behalf of the HypoVereinsbank Luxembourg
Societe Anonyme, our willingness to extend this loan to you.  This extending of
Euroloans is given under the reservation of the respective funds being available
on the Euromarket and in the event of this transaction being passed to our
subsidiary in Luxembourg, in accordance with the enclosed "Terms and Conditions
for Euroloans of the HypoVereinsbank Luxembourg Societe Anonyme".

According to the provisions of bank supervisory rules (Section 18  German
Banking Act (Kreditwesengesetz)), in the event of the extending of loans - prior
to the loan being extended as well as during the total duration of the loan
relationship - banks must examine the economic situation of the borrower, in
particular by inspection of annual accounts.

Upon acceptance of this loan agreement, you therefore obligate yourself to send

date of the balance sheet for the submission of annual accounts or, if these are
not completed, for the submission of equivalent documents.

Additionally, our General Terms and Conditions are applicable which are
available for examination in each branch office and which can be made available
to you at any time upon request.

                       Terms and Conditions for Euroloans

               of the HypoVereinsbank Luxembourg Societe Anonyme

The following terms and conditions apply to Euroloans of the HypoVereinsbank
Luxembourg Societe Anonyme (hereinafter referred to as "HypoVereinsbank
Luxembourg":

1.   Upon becoming due for payment, capital and interest shall be remitted,
     without any deductions, to the account of HypoVereinsbank Luxembourg at the
     Bayerischen Hypo- und Vereinsbank Aktiengesellschaft (hereinafter "Bank")
     (stated in the Euroloan confirmation letter of the HypoVereinsbank
     Luxembourg).  Interest shall be calculated according to the number of
     calendar days divided by 360.

2.   The HypoVereinsbank Luxembourg has been empowered by you to give the Bank
     instructions on your behalf upon maturity of the loan to remit to the
     HypoVereinsbank Luxembourg the amount required to cover the loan and the
     interest.  In this case, the HypoVereinsbank Luxembourg reserves the right
     to assign the loan claim against you, including any collateral directly
     provided for it, to the Bank.

3.   The HypoVereinsbank Luxembourg is herewith expressly empowered to obtain
     all information relating to you from the Bank which it considers to be
     necessary in connection with the loan.  Equally, it is herewith expressly
     empowered to give such information to the Bank.

4.   Should taxes, charges or other burdens (e.g., due to the implementation of
     a minimum reserve obligation, amendment to domestic or foreign currency
     provisions, etc.) be levied on the HypoVereinsbank Luxembourg in connection
     with the loan, and/or should such be increased, these shall be assumed by
     you in the full amount

5.   Land charges which you have taken out in favour of the Bank or which you
     have assigned or will assign to the Bank as well as objects and assigned
     claims which have been transferred to the Bank as collateral shall also
     serve to secure the respective claims of the HypoVereinsbank Luxembourg
     from the business relationship with you, in particular from the granting of
     loans.  The agreements on collateral concluded between you and the Bank
     shall be respectively applicable to the legal relationship between you and
     the HypoVereinsbank Luxembourg.

     All property, claims and other rights, to which the Bank has an entitlement
     to a lien based on its claims against you, shall serve as a lien against
     you for the claims of the HypoVereinsbank Luxembourg defined in the
     paragraph above. Insofar as the
<PAGE>

     lien of the HypoVereinsbank Luxembourg concerns moveable property, you
     shall herewith assign your present and future contractual claims for
     repossession against the Bank to the HypoVereinsbank Luxembourg.

     The HypoVereinsbank Luxembourg will obtain the approval of the Bank, as
     assignee, and your consent to concurrently hold the loan collateral in
     trust for the HypoVereinsbank Luxembourg.

6.   The HypoVereinsbank Luxembourg has the right to call in the loan with
     immediate effect for an important reason which makes a continuation of the
     loan unreasonable for the HypoVereinsbank Luxembourg, also after your
     justified concerns have been reasonably taken into account. In particular,
     such reason exists when you have made incorrect statements regarding your
     financial situation or if a substantial decrease of your assets or a
     substantial threat to your assets occurs, in particular, if enforcement
     (e.g., sale by public auction or judicially enforced receivership) in an
     encumbered piece of land is ordered, or if you cease payments, or if
     bankruptcy or settlement or similar proceedings are commenced against your
     assets.

7.   For borrowers with business seat or domicile in the Federal Republic of
     Germany:  German law shall apply for all legal relationships between you
     and the HypoVereinsbank Luxembourg.

     For borrowers with business seat or domicile outside the Federal Republic
     of Germany:  The laws of Luxembourg shall apply for all legal relationships
     between you and the HypoVereinsbank Luxembourg, place of jurisdiction for
     any disputes shall be Luxembourg or the responsible court at your business
     seat/domicile, according to the election of the HypoVereinsbank Luxembourg.
