For the avoidance of doubt, this Section 4.1 only provides for payment claims of the Sellers against the Purchaser and not for payment claims of the Purchaser against the Sellers. In particular Purchaser may not re-claim the First Earn-Out Payment in case the Second Earn-Out Payment does not become payable.

4.2 Determination of Earn-Out Payments

4.2.1 The Purchaser will provide to the Sellers before the end of the fourth (4^th) calendar month (Kalendermonat) after the last day of the respective Earn-Out Period

(a) true copies of the certified and approved consolidated group balance sheet and group profit and loss statement of the Companies regarding the respective Earn-Out Period (the Earn-Out Financial Statements). The Earn-Out Financial Statements shall be prepared (i) consistent with past practice (i.e., the practice applied in relation to the certified and approved consolidated group balance sheet and group profit and loss statement of the Company as of 31 December 2011 (Consolidated Financial Statements, attached hereto as Annex 4.2.1)), in particular, without limitation, maintaining the same accounting and valuation principles, methods and rules, and exercising consistently all options to capitalize or to include items on the liabilities side (Aktivierungs- und Passivierungswahlrechte), (ii) in accordance with IFRS and (iii) without any effects from purchase price accounting (i.e. any purchase price allocation of the Purchaser must take place on the level of a direct or indirect shareholder of the Company). In case of contradictions between the principles set out under (i) above and IFRS, the principles set out under (i) above shall prevail to the extent permitted by applicable law; with regard to purchase price accounting the principles set out under (i) shall in any event prevail. For the avoidance of doubt, with regard to facts and circumstances which have not been accounted or recorded for in the past (i.e. no established past practice), IFRS shall prevail;

(b) a calculation of the respective Earn-Out Payment (the Draft Earn-Out Calculation) in accordance with Sections 4.1.1 and 4.1.2 above, showing (i) the calculation of the Consolidated EBITDA on the basis of the respective Earn-Out Financial Statements and (ii) the calculation of the Earn-Out EBITDA on the basis of the Consolidated EBITDA; and

(c) the certificate of an auditor confirming that the respective Draft Earn-Out Calculation has been calculated in accordance with Sections 4.1.1 and 4.1.2 above (the Auditor Certificate). Such auditor shall be PricewaterhouseCoopers Aktiengesellschaft Wirtschaftsprüfungsgesellschaft. If PricewaterhouseCoopers Aktiengesellschaft Wirtschaftsprüfungsgesellschaft refuses to act and the Parties cannot mutually agree upon another accounting firm within ten Business Days after the Parties have become aware of the refusal to act, then each Party may request the speaker of the board (Xxxxxxxx des Vorstands) of the Institute of Chartered Accountants (Institut der Wirtschaftsprüfer), Düsseldorf, to determine the accounting firm.

4.2.2 The Sellers may review the respective Draft Earn-Out Calculation or have it reviewed by an auditor of their choice. All costs arising from or in connection with such review shall be borne by the reviewing party alone.

4.2.3 The respective Draft Earn-Out Calculation shall become the respective final earn-out calculation (the Earn-Out Calculation) if the Sellers do not notify the Purchaser within 30 calendar days (Kalendertage) from receipt of the Draft Earn-Out Calculation that the Sellers have objections to the Draft Earn-Out Calculation, specifying the items to which the Sellers object in reasonable detail.

4.2.4 In the event that the Sellers notify the Purchaser within 30 calendar days from receipt of the Draft Earn-Out Calculation in accordance with Section 4.2.3 that the Sellers have objections to the Draft Earn-Out Calculation, the Sellers and the Purchaser shall then attempt to reach an agreement on the adjustments to such Draft Earn-Out Calculation, if any, within two weeks from receipt of such notice by the Purchaser. To the extent that the Sellers and the Purchaser reach an agreement on the items on dispute within such two week period, such agreement shall be incorporated into the Draft Earn-Out Calculation. To the extent of the agreement reached between the Sellers and the Purchaser, the Draft Earn-Out Calculation shall upon such incorporation become the Earn-Out Calculation.

4.2.5 In the event that the Sellers and the Purchaser do not reach an agreement within the two week period referred to in Section 4.2.4 above, the Sellers and the Purchaser shall jointly appoint one expert (Schiedsgutachter) not later than ten calendar days after the expiry of such two weeks period. With regard to the objections that are still in dispute between the Parties after the procedure in Section 4.2.4 above has been followed, such expert shall be instructed to decide the disputed objections in accordance with the principles mentioned in Sections 4.1.1 and 4.1.2 above, and to deliver a written opinion within four weeks after its appointment, which opinion shall be final and binding on the Sellers and the Purchaser. The opinion shall be incorporated into the Draft Earn-Out Calculation which, upon such incorporation, shall become the Earn-Out Calculation.

4.2.6 If the parties do not reach an agreement on the appointment of the expert within a period of ten calendar days after the expiry of the two week period referred to in Section 4.2.4 above, than the expert shall be appointed upon the request of either the Sellers or the Purchaser by the speaker of the board (Xxxxxxxx des Vorstands) of the institute of chartered accountants (Institut der Wirtschaftsprüfer), Düsseldorf. Such expert shall be from an international accounting firm.

4.2.7 In the first instance, the Sellers shall collectively bear and advance 50 per cent of all costs and expenses of the expert and the proceedings hereunder, and the Purchaser shall bear and advance 50 per cent of such costs and expenses. Each of the Sellers and the Purchaser shall bear their own costs and the costs of their respective advisors and counsel, except to the extent that the expert decides otherwise in accordance with the following sentence. The expert may decide in its equitable discretion upon the final allocation of its costs and expenses as well as the costs and expenses of the proceedings hereunder between the Sellers and/or the Purchaser, including reasonable fees and expenses of the Sellers and the Purchaser and their advisors and counsel in these proceedings, taking into account the decision and original positions and motions of the Sellers and the Purchaser.

10.2 Tax Indemnification

10.2.1 The Sellers shall indemnify the Purchaser from and against all Taxes if and to the extent they relate to the Companies or the Participation and are allocable to a period ending on or prior to the Effective Date (or portions thereof) (such Taxes the Indemnified Taxes). With regard to Indemnified Taxes, each Seller will be severally (but not jointly) liable in the proportion that the registered share capital of the Company represented by the Shares of such Seller bears to the total registered share capital of the Company. With respect to Taxes relating to the Participation, the amount of the Indemnified Tax shall be the amount of the relevant Tax (net of any limitation pursuant to Section 10.2.2 if and to the extent applicable) multiplied by the Company’s indirect shareholding percentage (durchgerechnete Beteiligung) as sold under this Agreement.

10.2.2 Sellers shall only be liable for Indemnified Taxes if and to the extent

(a) the Indemnified Tax is not a Tax Audit Tax that decreased the Initial Purchase Price in accordance with Section 3.1.1; and

(a) the Indemnified Tax is caused or increased by a reorganization or other measure initiated or executed after the Closing Date by the Purchaser or any of the Companies or the Participation provided such reorganisation or other measure legally relates to (i.e., has for tax purposes a retroactive impact – steuerlich rückwirkend—on) a period ending on or prior to the Effective Date (e.g., but not limited to, a change of the exercise of any Tax election rights which is made for a fiscal year which pertains to a period ending on or prior to the Effective Date, or a transaction which for tax purposes has a retroactive effect to a period ending on or prior to the Effective Date by operation of law); for the avoidance of doubt, this Section 10.2.3 (a) shall not apply to any change in the transfer pricing policy for periods after the Effective Date, any reorganization of any of the Companies or the Participation which takes effect for Tax purposes only from a date after the Effective Date, or the request that a tax field audit is conducted; or

(b) the Indemnified Tax corresponds to or can be offset against future Tax reductions (Steuerminderungen) arising after the Effective Date at the level of the Purchaser or any of the Companies or the Participation and out of a circumstance having triggered a Tax indemnification claim, including but not limited to reciprocal effects (Wechselwirkungen) resulting e.g. from the extension of depreciation periods or higher depreciation allowances (Phasenverschiebung) or from transfer of items relevant for Indemnified Taxes (e.g. turnover, income, expenses, VAT payable corresponding with a VAT refund) into another calendar year or transfer of Tax items from one entity to another entity; if Sellers claim that there is a specific Tax reduction arising after the Effective Date at the level of the Purchaser or any of the Companies or the Participation out of the circumstance having triggered the Tax indemnification claim, there will be a rebuttable presumption (widerlegbare Vermutung) that the relevant circumstance gives rise to the claimed specific Tax reduction; it being understood that Purchaser’s Tax indemnification claim shall be reduced by the net present value of such Tax reduction determined as at the time the respective Indemnified Tax is assessed, such net present value to be determined on the basis of the Tax rate applicable at that time and a discount rate of 5 % p.a.

For the avoidance of doubt, the Sellers shall not indemnify the Purchaser for Taxes other than the Indemnified Taxes.

10.2.4 Indemnification payments due by the Sellers under this Section 10 shall be made three Business Days prior to the due date of the Indemnified Tax but not earlier than ten Business Days following written notice by the Purchaser of the assessment of an Indemnified Tax by a Tax Authority or a court of proper jurisdiction and the Sellers have received a copy of the underlying Tax assessment.

10.3 Tax Covenants

The Purchaser covenants to the Sellers that after the Closing Date the Purchaser will not, and will not cause or permit any of its Affiliates (including, without limitation, after the Closing the Companies) to,

(a) take any action that gives rise to an additional Tax liability of the Sellers, their Affiliates or the Companies or results in any increase thereof or in the loss or the reduction of any Tax Refund of the Companies or the Participation;

(b) – if it has an impact on Indemnified Taxes or a Relevant Tax Proceeding relating thereto – make or change any Tax election, amend any Tax return or take any Tax position, take any action, omit to take any action or carry out any transaction, merger or restructuring that would increase any Tax liability of the Companies;

however, in each case only if the relevant action as set forth under lit. a or lit. b legally relates to (i.e., has for tax purposes a retroactive impact – steuerlich rückwirkend—on) a period ending on or prior to the Effective Date (e.g., but not limited to, a change of the exercise of any Tax election right which is made for a fiscal year which pertains to a period ending on or prior to the Effective Date, or a transaction which for tax purposes has a retroactive effect to a period ending on or prior to the Effective Date by operation of law) and unless (i) the relevant action as set forth under lit. a or lit. b is compelled by mandatory law and the Purchaser has given sufficient opportunity to the Sellers to intervene or (ii) the Sellers have given their prior written consent to the Purchaser. For the avoidance of doubt, this Section 10.3 shall not apply to any change in the transfer pricing policy for periods after the Effective Date, any reorganization of any of the Companies which takes effect for Tax purposes only from a date after the Effective Date or the request that a tax field audit is conducted.

10.4.4 If the Sellers elect by a written request to lead an appeal and/or Tax court proceeding against a Tax assessment relating to a Relevant Tax Proceeding (Tax Litigation) on their own or through counsel of their choice and at their expense, then the Purchaser shall, to the extent legally permissible, promptly authorize, and shall cause the respective Companies to authorize (by power-of-attorney and such other documentation as may be necessary or appropriate) the designated representative of the Sellers to represent the Purchaser and the respective Companies in the Tax Litigation. If the Sellers have elected to lead a Tax Litigation, Sellers shall keep the Purchaser informed of the status and outcome of the Tax Litigation without undue delay; in particular, Sellers shall provide the Purchaser with copies of all material written correspondence with the respective Tax Authorities and/or Tax court which relate to the Tax Litigation. In any case the Purchaser shall procure that after the Closing Date (i) no material document or other material written information related to Indemnified Taxes or Relevant Tax Proceedings is submitted to any Tax Authority or Tax court without the prior written consent of the Sellers, which shall not be unreasonably withheld, and that (ii) no Relevant Tax Proceeding is settled or becomes time-barred without the prior written consent of the Sellers.

11.2 Merger Control Proceedings; Other Regulatory Requirements

11.2.1 The Purchaser and, where applicable, the Sellers shall ensure that any initial filings to be made with the competent merger control authorities or other public authorities in the United States of America and China, to the extent they have not already been made prior to the Signing Date, will be made within one month after the Signing Date, unless the applicable laws and regulations require an earlier filing. Where possible, such filings shall be made by the Purchaser and the Sellers jointly. In all other cases, such filings shall be made by the Purchaser on behalf of all Parties, provided, however, that the contents of such filings shall require prior written approval of the Sellers, which shall not be unreasonably withheld. In case separate filings by the Purchaser and the Sellers are required, the Parties will make such separate filings. In order to obtain all requisite clearances (including as a result of the expiry of any applicable waiting period) for the transaction contemplated by this Agreement under merger control laws, all Parties shall: (i) reasonably cooperate in all respects with each other in the preparation of any filing or notification and in connection with any submission, investigation or inquiry, (ii) without undue delay provide all other Parties with copies of any material correspondence with the merger control or other public authorities and with copies of any written statement, order or decision of such authorities, (iii) comply as promptly as possible with all reasonable requests from the competent authorities, and (iv) closely cooperate in any discussions and negotiations with the competent authorities with the objective to obtain clearance or to cause any applicable waiting periods to commence and expire for the transaction contemplated by this Agreement in the shortest time period possible. To the extent that this Section 11.2.1 requires the Parties to exchange competitively sensitive information, the information shall only be exchanged between the respective antitrust advisors of the Parties. The Parties may waive (zurücknehmen) filings with the competent authorities or agree with such authorities on the extension of any examination period only with the express prior written consent of the respective other Parties.

11.2.2 If the competent authorities in the United States of America are prepared to grant their approval only subject to compliance with specific conditions or obligations to be imposed upon the Purchaser or the Companies, the Purchaser shall offer (or accept the imposition of) such conditions and obligations at its own cost and risk, unless such conditions or obligations, taking into account any actions taken or that can reasonably be taken to cure or limit the effect of any such conditions or obligations, have or may reasonably be expected to have such a material adverse effect on the net worth, financial condition, results of operations (Vermögens-, Finanz- oder Ertragslage) of the Companies and the Purchaser’s group (taken as a whole) that the Purchaser may no longer reasonably be expected to consummate the transaction contemplated herein. The Purchaser shall offer, consent to, and comply with, and shall ensure that any Purchaser’s Affiliates will, offer, consent to, and comply with, any obligations or conditions, commitments or other agreements required by the competent merger control authority in the United States of America as a condition to the clearance of the transactions contemplated hereby, unless such conditions or obligations, taking into account any actions taken or that can reasonably be taken to cure or limit the effect of any such conditions or obligations, have or may reasonably be expected to have such a material adverse effect on the net worth, financial condition, results of operations (Vermögens-, Finanz- oder Ertragslage) of the Companies and the Purchaser’s group (taken as a whole) that the Purchaser may no longer reasonably be expected to consummate the transaction contemplated herein. The Purchaser further agrees to defend through litigation on the merits any claim asserted in court by the competent US merger control authorities in order to avoid entry of, or to have vacated or terminated, any decree, order or judgment (whether temporary, preliminary or permanent) that would prevent the Closing to occur prior to 31 May 2013; provided, however, that such litigation in no way limits the obligation of the Purchaser to accept or offer conditions or obligations as per the preceding sentence in order to close the transaction contemplated hereby prior to 31 May 2013. If the competent merger control authorities in China are prepared to grant their approval only subject to compliance with specific conditions or obligations to be imposed upon the Purchaser or the Companies, the Purchaser shall consider in good faith whether or not to accept any such condition or obligation, but will not be required to accept any such condition or obligation.

11.2.3 If on the Closing Date any merger control approval or any other governmental consent, approval or waiver that may be required under applicable law in any jurisdiction (other than USA and China) in order to effect the Closing has not been obtained, the Sellers and the Purchaser shall consummate the Closing. The Sellers and the Purchaser shall in such case agree on all appropriate measures, including “hold separate” arrangements, regarding the business affected, in order that the relevant jurisdiction can be exempted from the consummation of the transaction until the required consents and approvals have been obtained.

11.5.3 Unless and until the Purchaser has notified the Sellers in accordance with Section 11.5.4 (in particular the time period set out therein) that it will continue the financing under the Financing Agreements in whole or in part, the Sellers shall provide the Purchaser at Closing with an executed original of a final security release agreement (the Purchaser Release Agreement) pursuant to which, subject to the payment in full of the Pay-Off Amount (as defined below) set forth in or with reference to the Purchaser Release Agreement, all Financing Collateral will be immediately released and, as applicable, cancelled, reassigned or retransferred to the relevant party having constituted such security interest. The Parties agree that the Pay-Off Amount (the Pay-Off Amount) will be the aggregate amount of all claims payable under the Financing Agreements (including principal, interest, commitment and other recurring fees then due and including all such amounts then outstanding and due under any ancillary facilities, any break costs, prepayment fees or penalties, settlement costs, compensation payments, damages or similar claims in connection with the prepayment and/or termination of the Financing Agreements) as of the anticipated Closing Date (the Anticipated Closing Date).

The Parties agree that the Purchaser may discuss and agree with the Companies whether to use those hedging agreements to swap the US-Dollar payment into Euros for the payment of the Pay-Off Amount, and the Purchaser is aware that those hedging agreements will have to be settled if they are not used for this purpose. The Purchaser Release Agreement shall set forth the account or accounts to which the Pay-Off Amount (including any Daily Interest, if applicable)) must be paid (in whole or in parts) (the Pay-Off Accounts). The Sellers shall use commercially reasonable efforts to procure that the Purchaser Release Agreement either sets forth a daily interest payable in connection with the Senior Facilities Agreement and the Pay-Off Amount should Closing not occur on the Anticipated Closing Date but be delayed for any reason (the Daily Interest) or sets forth that the Release Amount will not only be calculated for the Anticipated Closing Date but for a certain number of days following the Anticipated Closing Date, and that the Companies, or the Purchaser on their behalf, are permitted to prepay and/or repay the Release Amount on, or within a reasonable period after, the Anticipated Closing Date without the giving of any further notice or the observation of any notice or other periods. The Sellers shall further use commercially reasonable efforts to procure that the Purchaser Release Agreement provides that, subject to the full payment of the Pay-Off Amount, all of the Sellers’ and the Companies obligations and liabilities under or in connection with the Financing Agreements are unconditionally and irrevocably discharged in full and all Financing Agreements terminated. Otherwise, the Purchaser Release Agreement shall be materially in a customary form that gives effect to its provisions and comply with the requirements of applicable law. The Sellers shall procure that the Pay-Off Amount and a copy of the executed, or the final draft of the, Purchaser Release Agreement is provided to the Purchaser no later than 4 Business Days prior to the Closing Date.

11.5.4 The Purchaser will investigate if and to what extent it is interested in continuing the financing under the Financing Agreements in whole or in part. The Sellers shall, and shall procure that the Companies will, permit the Purchaser to discuss and negotiate any such continuation with the Finance Parties. If the Purchaser notifies the Sellers by no later than 31 August 2012 that it will continue the financing under the Financing Agreements in whole or in part,

(a) the Sellers shall support, and shall use reasonable endeavors that the Companies support (including through entering into agreements and making legal declarations), as far as legally permitted and reasonably requested by the Purchaser, the Purchaser in relation to the continuation of the financing under the Senior Facilities Agreement, provided that the Sellers will in no event be required (i) to incur any financial obligation, or (ii) to procure that any Company enter into any agreement that would become effective before the completion of the Closing, or (iii) to procure that any Company incur any financial obligation that would become effective before the completion of the Closing; and

(b) the Purchaser shall procure that, by the Closing Date, a release agreement is offered by the relevant Finance Parties with respect to the Share Pledge Agreement whereby the pledges over the Shares and any ancillary rights pledged under the Share Pledge Agreement are released (Aufhebung des Pfandrechts) and the Sellers are released from all their obligations and liabilities resulting from and relating to the Share Pledge Agreement and the Security Trust Agreement (the Seller Release Agreement).
