(the „Bank“)

have entered into an Agreement (the „Credit Facility Agreement“) pursuant to which the Bank makes available a revolving umbrella credit facility to the Borrower (the “Umbrella-Credit Facility”) on the basis of the Bank’s General Business Conditions (Allgemeine Geschäftsbedingungen). The Credit Facility Agreement will be amended by the 2^nd Amendment as follows:

The Bank makes available to the Borrower a credit facility in the amount of up to

Euro 30,000,000.00 (in words: Euro Thirty Million) („Aggregate Facility Amount“).

(2)    Term of the Facilities

The Facilities are available until July 31^st, 2017 (“Term of the Umbrella-Credit Facility”).

The use of Facility 1 for acquisitions irrespective of form, duration and amount will require the prior consent of the Bank.

In this Credit Facility Agreement the following words and terms are defined as specified below:

„Banking Day“ means a day (other than a Saturday or Sunday) on which banks are open for general business in Cologne.

„EONIA“ means the Euro OverNight Index Average as determined by the European Central Bank for each Target-day. On days which are not a TARGET-day the EONIA as determined on the immediately preceding TARGET-day shall apply. If no EONIA is available on a Target-day the Bank will determine the applicable reference interest rate in accordance with section 315 German Civil Code (BGB) on the basis of the quotations for overnight funds in the European interbank market.

„EURIBOR“ means the interest rate per annum for deposits in Euro for the relevant interest period displayed on page 248 of the Telerate screen or a respective succeeding screen replacing page 248 for 11.00 a.m. Brussels time two TARGET-days prior to the disbursement/the commencement of the respective interest period. If the EURIBOR cannot be determined two TARGET-days prior to the first interest period, the Bank and the Borrower will negotiate the interest rate for the relevant interest period. The Bank is not obligated to

disburse the loan unless an agreement about the applicable interest rate has been reached. The Bank is released from its obligation to disburse the loan if an agreement about the applicable interest rate is not reached within 15 days. If the EURIBOR for an interest period following the first interest period cannot be determined two TARGET-days prior to the commencement of the relevant interest period the Bank will determine interest for the relevant interest period based on interest rates customary in the European interbank market for the particular interest period plus the agreed margin.

"Financial Indebtedness" means any indebtedness for or in respect of (i) moneys borrowed, (ii) any letters of credit issued and acceptances accepted or issued, which had been discounted, (iii) any amount raised pursuant to any note purchase facility or the issue of bonds, notes, debentures, loan stock or any similar instrument, (iv) lease contracts which would, in accordance with orders or statements of practice of the Federal Ministry of Finance or GAAP under the applicable law as the case may be, be treated as a finance or operating lease, (v) receivables sold or discounted (other than any receivables to the extent they are sold on a non-recourse basis), (vi) any amount raised under any other transaction (including any forward sale or purchase agreement) having the commercial effect of a borrowing, (vii) any derivative transaction entered into in connection with protection against or benefit from fluctuation in any rate or price (and, when calculating the value of any derivative transaction, only the marked to market value shall be taken into account), (viii) any counter-indemnity obligation in respect of a guarantee, indemnity, bond, standby or documentary letter of credit or any other instrument issued by third parties unless both obligations are reported, the primary obligation on and the obligation of the counter-indemnity on or below, the same balance sheet; and (ix) the amount of any liability in respect of any guarantee or indemnity for any of the items referred to in paragraphs (i) through (viii) above, (x) a guarantee, surety or other obligation for any of the obligations listed in paragraphs (i) through (ix), and (xi) provisions for pension obligations.

„TARGET-day“ is any day on which the Trans-European Automated Real Time Gross Settlement Express Transfer System is open for the settlement of payments in Euro.

Current account cash advances (“Cash Credit”) in Euro on the account of the Borrower with IBAN DE34460700900028025500, BIC DEUTDEDK460.

Loans with fixed interest rates on the basis of EURIBOR with interest periods of 1, 3, or 6 months which may, however, not extend beyond the Term of Facility 1 (“Interest Period”) (“EURIBOR-Fixed Interest Loan”) in Euro after a utilization request by the Borrower. The minimum amount for utilizations by way of EURIBOR-Fixed Interest Loan is

Each utilization request must be delivered to the Bank by 10:00 a.m. Frankfurt am Main local time two Banking Days before the day on which disbursement is to be made or on which, a new Interest Period would begin, respectively. The utilization request must specify the designated amount of the utilization and the duration of the Interest Period and shall be irrevocable.

If an Interest Period would otherwise end on a day which is not a Banking Day, that Interest Period will instead end on the next Banking Day in that calendar month (if there is one) or the preceding Business Day (if there is not).

Cash Credit in foreign currency, namely in US Dollar, or with prior consent of the Bank in every other currency which is freely available, convertible and transferable in the European interbank market.

Facility 2 may be utilized as follows:

Facility 2 may be utilized through sureties (Bürgschaften), sureties upon first demand (Bürgschaften auf erstes Anfordern), guarantees (including bonds and standby letters of credit) or guarantees upon first demand (Garantien auf erstes Anfordern) issued upon instruction of the Borrower (“Guarantees”) in EUR and if individually agreed upon also in foreign currency. Unless otherwise agreed on a case by case basis, the instructions to issue the Guarantees shall be given using the wording in each case prepared by the Bank.

Guarantees and sureties other than bid bonds, advance payment bonds, performance bonds and warranty bonds requires the consent by the bank before issuance.

In addition, the Special Conditions for Guarantee Business of the Bank (Bedingungen für das Avalgeschäft), as attached to this Credit Facility Agreement, shall apply, which take priority over the Bank’s General Business Conditions.

Before accepting an instruction to issue a Guarantee, the Bank is entitled to consider such instruction with respect to its feasibility under legal, economical and policy aspects and to refuse acceptance, as the case may be.

Each Guarantee shall be limited in time and shall not exceed a term of 3 years. Where a Guarantee does not qualify for a limited term, the economic lifetime (until the expected expiration of the Guarantee) shall not exceed 3 years.

Instructions can been given for Guarantees to be issued in foreign currency, namely in US Dollar, or with prior consent of the Bank in every other currency which is freely available, convertible and transferable in the European interbank market up the Aggregate Facility Amount of Facility 2.

Facility 3 may be utilized by entering into financial derivatives transactions (each a “Transaction”) on the basis of separate master agreements entered or to be entered into between the Bank and the Borrower.

By granting the revolving margin line the Bank expresses its general willingness to incur a potential future exposure resulting from such Transactions, up to the limit of the revolving margin line. The Bank shall, however, not be in any way obliged to enter into specific Transactions. In particular, the Bank reserves the right to reject Transactions on a case by case basis, even if Facility 3 is not fully utilized. This does not apply to Transactions intended to offset obligations under already existing Transactions (“Close-Out Transactions”) and which are entered into in order to close open risk-positions of the Bank.

On a regular basis - if need be, on each Banking Day or several times during a Banking Day - the Bank will calculate the margin line utilization as potential future exposure based on the Bank’s own internal calculation methods and risk models, and using the interest rates, forward rates, quotations, market prices, indices or other calculation bases as determined by it. In determining the utilization of Facility 3, the Bank will take into account if and to what extent the potential future exposures resulting from Transactions under a master agreement can be offset. Upon request, the Bank will inform the Borrower of the current utilization of Facility 3.

Should Facility 3 be exceeded - e.g. in the course of changing market conditions - the Borrower shall ensure that, upon the Bank’s request, appropriate measures are taken to either reduce the potential future exposure or to provide the Bank with sufficient collateral to cover the excess utilization, e.g. by providing additional collateral or by entering into a new collateral agreement. The reduction of potential future exposure may also be effected by entering into Close-Out Transactions or by early terminating specific Transactions by way of mutual agreement. If - for whatever reason - the Borrower does not comply with the Banks´ request for additional collateral, a new collateral agreement or a reduction of potential future exposure, the Bank shall have the right to terminate the respective master agreement including all Transactions thereunder, provided that it notifies the Borrower of its intention to terminate the master agreement, which notification may be combined with the Bank’s above-mentioned request, and further provided that it grants the Borrower an appropriate grace period which - under special circumstances - may only be a few hours.

All other provisions of the master agreement and the Transactions thereunder shall remain unaffected by this Credit Facility Agreement.

Subsidiaries of the Borrower may - in deduction from the respective Facility and based on the corporate guarantee by the Borrower (hereinafter the “Corporate Guarantee”) as set out in the Annex to this Credit

Facility Agreement - draw credits and use banking products (hereinafter: “Subsidiary Facilities”) within the banking business relationship at domestic or foreign branches and / or subsidiaries of the Bank (hereinafter “Lending Office”) in compliance with the following conditions. No Lending Office shall be obliged hereby to make available Subsidiary Facilities.

The utilization of Subsidiary Facilities by the respective Subsidiary shall be based on separate facility agreements concluded or to be concluded between the respective Subsidiary and the Lending Office.

The current allocation of the Subsidiary Facilities to the respective Subsidiaries as well as to the respective Lending Offices shall be reflected in Annex 1 as attached to the Corporate Guarantee at any point of time. In case of a change of the current allocation of the Subsidiary Facilities, Annex 1 of the Corporate Guarantee shall be amended accordingly; in case of such amendment, the provisions contained in this Credit Facility Agreement shall remain unaffected.

(3)    Exemption from Banking Secrecy

Vis-a-vis the other Lending Offices the Borrower releases the Bank from the obligations of Banking Secrecy with respect to all matters concerning this Credit Facility as well as the Subsidiary Facilities.

The Borrower is entitled to provide the Bank and/or the Lending Office, respectively, instead with security by pledge of the amount of the potential future exposure in cash (or any other amount to be agreed with the Bank and/or the Lending Office, or to procure that the respective Subsidiary provide such security in cash.

A reasonable cause which entitles the Bank to terminate this Credit Facility Agreement without notice according to no. 19 section 3 of the General Business Conditions is also and especially given if:

The termination of Facility 3 (revolving margin line) will be governed exclusively by the provision of the underlying master agreement for financial derivatives transactions.

All other terms and conditions of the Credit Facility Agreement remain unaffected by this amendment.
