(iii)	an amount of EUR 7,500,000.-- (in words: Euro seven Million five hundred thousand) (“HSP 2 Escrow Amount”).

On the Closing Date, subject to the terms of this Agreement, the Purchaser shall pay (i) the Estimated Cash Amount to the Joint Sellers' Account (ii) the Escrow Amount to the Escrow Account and (iii) the HSP 2 Escrow Amount to the HSP 2 Escrow Account.

Clause 6.2 shall apply mutatis mutandis to the allocation and apportionment of the Estimated Share Purchase Price.”

2.3.3    Clause 7.5 of the Principal Agreement shall read as follows:

“7.5	Reference Date Accounts and Final Determination of the Share Purchase Price

7.5.1

Sellers shall prepare and Purchaser shall procure that the Company fully assists Sellers in preparing the consolidated financial statement of the Group for the period from 1 January 2015 until the Reference Date, consisting of a balance sheet (Bilanz) and a profit and loss statement (Gewinn- und Verlustrechnung) in accordance with past practice (the "Reference Date Accounts"), as well as a statement setting forth the calculation and value of the following items

consistent with the relevant format used in Annex 7.1.2, 7.1.3, 7.1.4, respectively (items (i) through and including (v) together the "Financial Statement").

The Reference Date Accounts shall be prepared in accordance with the provisions of the HGB and German generally accepted accounting principles ("German GAAP") and the same assumptions, policies, methodologies and rules shall be applied which have been applied in preparing the Group's financial statements for the last financial year as in

9

---

particular set forth in the attachments and reports to the respective financial statements. The Reference Date Accounts and the Financial Statement shall not be audited and shall be delivered to the Purchaser (for review by Purchaser and/or an auditor selected by Purchaser) as soon as reasonably practical after the Closing Date, but in no event later than eighty (80) Business Days after the Reference Date.

Each Party shall bear its own costs and the costs of its respective advisors with respect to the preparation or review, as the case may be, of the Reference Date Accounts and Financial Statement.

7.5.2

Purchaser shall, after the Closing Date, ensure that Sellers and their advisors, accountants and representatives are (subject to customary release letters and hold harmless letters) granted all such access (however, only during business days and normal business hours) to records, premises and personnel of the Group as they may reasonably request for purposes of preparing and solving any disputes between the Parties regarding the Reference Date Accounts and the Financial Statement pursuant to and in accordance with clause 7.5.1. Purchaser shall instruct the management and staff of the Company and their advisors, accountants and representatives to co-operate with all such persons as reasonably requested by Sellers. The Parties shall endeavor that the auditor(s) acting or appointed in accordance with this Agreement with regard to the preparation and/or review of the Reference Date Accounts and/or the Financial Statement grant each other access to their respective working papers.

7.5.3

The Reference Date Accounts and the Financial Statement become final and binding for purposes of this Agreement as between the Parties if and to the extent the Purchaser does not within thirty (30) Business Days after receipt of both, the Reference Date Accounts and the Financial Statement, object to the Reference Date Accounts and/or the Financial Statement by providing the Sellers with (i) a written statement of objections, specifying in reasonable detail the grounds for the objections, and (ii) a revised version of the Reference Date Accounts (the "Revised Reference Date Accounts") and a revised version of the Financial Statement (the "Revised Financial Statement") taking into account such objections and the changes which are necessary in Purchaser's view to comply with the requirements of this Agreement. Each Party shall bear its own costs and the costs of its respective advisors with respect to the preparation or review, as the case may be, of the Revised Reference Date Accounts and Revised Financial Statement.

7.5.4

If Purchaser properly objects in compliance with clause 7.5.3 to the Reference Date Accounts and/or the Financial Statement within thirty (30) Business Days after receipt of the Reference Date Accounts and the Financial Statement, the Parties shall endeavor in good faith to settle the disagreement. If Sellers and Purchaser reach an agreement, the Reference Date Accounts and the Financial Statement, as varied by such agreement, shall become final and binding on the Parties for purposes of this Agreement. If and to the extent Sellers and Purchaser fail to settle the disagreement within fifteen (15) Business Days (or such other time period as the Sellers and the Purchaser may agree upon in writing) after receipt by the Sellers of Purchaser's statement of objections, the Parties shall jointly appoint an auditor who shall resolve the dispute between the Parties (the "Neutral Auditor") unless otherwise agreed upon by the Parties. The Neutral Auditor shall belong to the service network of any of the “big four” other than Ernst & Young (i.e. PwC, KPMG, or Deloitte). If the Parties are unable to agree on a Neutral Auditor within ten (10) Business Days, each Party shall have

10

---

the right to refer the matter to the German Institute of Chartered Accountants (Institut der Wirtschaftsprüfer in Deutschland e. V.) to determine the Neutral Auditor (such determination to be final and binding on the Parties). The Neutral Auditor shall act as an arbitral expert (Schiedsgutachter) within the meaning of Section 317 of the German Civil Code (Bürgerliches Gesetzbuch - "BGB") and its decision, which shall be made in accordance with the provisions of this clause 7.5, and the Reference Date Accounts and Financial Statement as amended by the Neutral Auditor, shall be binding and final upon the Parties (in the absence of manifest material error). Unless instructed otherwise by Sellers and Purchaser jointly, the items determined by the Neutral Auditor may not be above or below the figures proposed by Sellers and Purchaser, respectively. Any costs and expenses incurred by the Neutral Auditor and in relation to the dispute over the Reference Date Accounts and/or the Financial Statement shall be allocated and borne by the Parties in accordance with Section 91 et seq. of the German Civil Procedure Act (Zivilprozessordnung - "ZPO") which shall apply accordingly.

7.5.5

Sellers and Purchaser shall, within the subsequent five (5) Business Days after appointment of the Neutral Auditor, each prepare and deliver to the Neutral Auditor a written statement on the items in dispute, make available to the Neutral Auditor the Reference Date Accounts, the Revised Reference Date Accounts, the Financial Statement and the Revised Financial Statement and all other documentation and data reasonably required by the Neutral Auditor to make the required decisions and determination. The Neutral Auditor shall immediately submit copies of all documents and other data made available by Sellers or Purchaser to the respective other Parties as well. The Parties shall be given the opportunity to present their views in English in writing and at an oral hearing in the presence of Sellers and Purchaser and their professional advisors. The Parties shall use their best efforts to obtain the written decision of the Neutral Auditor with reasons for the decisions as soon as reasonably practicable. The Neutral Auditor shall be asked to send his/her decision in writing to the Parties within forty-five (45) days of the confirmation and acknowledgment by the Neutral Auditor of its appointment hereunder.

7.5.6	The Reference Date Accounts and Financial Statement or Revised Reference Date Accounts and Revised Financial Statement, as the case may be, that have become final and binding upon the Parties for purposes of this Agreement pursuant to and in accordance with clauses 7.5.3 through 7.5.5 are referred to herein as the "Final Reference Date Accounts" and the "Final Financial Statement".

The Reference Date Cash, Reference Date Debt, Reference Date NWC, Reference Date NWC Deviation, Share Purchase Price and Purchase Price Adjustment, in each case, shall be as set out in the Final Financial Statement.”

2.3.4    Clause 7.6.2 of the Principal Agreement shall read as follows:

"7.6.2

Any such amount pursuant to clause 7.6.1 (i) or clause 7.6.1 (ii) to be paid by either Purchaser or Sellers pursuant to and in accordance with clause 7.6.1 (each a "Purchase Price Adjustment") shall bear interest from the Closing Date until but excluding the date of payment at a rate of 5% (calculated daily on the basis of a year of three hundred sixty (360) days and payable at the same time as the payment to which it relates) and shall be paid within ten (10) Business Days after the Final Reference Date Accounts and Final Financial

11

Statement have become final and binding upon Sellers and Purchaser in accordance with clause 7.5."

each on a consolidated basis of the Group and calculated in accordance with German GAAP and applying the same assumptions, policies, methodologies and rules which have been applied in preparing the Group`s financial statements for the past business years including the Reference Date Accounts. For the avoidance of doubt, the sections of the German Commercial Code (HGB) referred to in this clause 9.2 shall have the meaning as set forth in the German Commercial Code (HGB) as of the Signing Date (except as otherwise stated herein); future changes to the German Commercial Code (HGB), in particular the choice of applying future changes to the German Commercial Code (HGB) with retro-active effect, shall be disregarded for the purpose of the definition of EBITDA pursuant to this clause 9.2."

"13.5

Subject to clause 13.6 below, the Purchaser undertakes to ensure during the period commencing as of the Closing and ending on and including the Reference Date (“Reference Date Period”) that the relevant business of the Company and its Subsidiaries is managed with the diligence of a prudent businessman and exclusively within the ordinary course of business and in accordance with past practice (“Relevant Management Standards”).

In particular, but without limitation to the generality of the foregoing, during the Reference Date Period, subject to clause 13.6 below, the Purchaser shall procure that none of the Group Companies will, without the Sellers’ prior written approval, carry out any of the actions set out in clauses 13.2.1 through 13.2.14 (it being understood that, for purposes of this clause 13.5, any reference made in clauses 13.2.1 through 13.2.14 to the Purchaser shall be deemed to be a reference to any Seller and any reference in clauses 13.2.1 through 13.2.14 to a Seller shall be deemed to be a reference to the Purchaser).

14

---

For the avoidance of doubt, Sellers shall not unreasonably withhold or delay their consent, provided, however, that Sellers shall in any case be entitled to withhold their consent in case the respective action is in the reasonable view of the Sellers likely to adversely affect or influence the Reference Date Accounts and thus the determination of the Share Purchase Price. In case Sellers do not react to the request for approval within a period of five (5) Business Days upon its receipt such approval shall be deemed to be granted.

Notwithstanding anything in this Agreement to the contrary, the Purchaser and the Group Companies are after Closing entitled to take all actions and/or do such other things (in each case only to the extent such actions and/or other things are in compliance with applicable law) as may be necessary to:

(i)	comply with any applicable mandatory law or any mandatory order of any competent public or judicial authority or existing contracts to which any of the Group Companies is a party; or

(ii)	comply with this Agreement.

13.6

The Parties agree that, only for the purposes of clause 13.5 and provided that the Purchaser has not appointed new managing directors of the Company and has not directed the Company to appoint new managing directors of any other Group Companies, any acts, measures or omissions from the Group Companies that are not based on an explicit instruction by the Purchaser in its capacity as the sole shareholder in the Company (either directly vis-à-vis the managing directors of the relevant Group Company or - if an advisory board of a Group company exists and is capable of directing the managing directors of such Group Company (which the Parties agree is currently not the case) - indirectly through such advisory board) (it being understood that Sellers shall be obliged to evidence such instruction by the Purchaser), shall be considered to comply with the Relevant Management Standards, i.e. the Purchaser shall only be considered to be in breach of its obligations pursuant to clause 13.5, if and to the extent the Purchaser actively (through its shareholder rights) directs a Group Company to carry out or omit any act or measure, and such act, measure or omission does not comply with the Relevant Management Standards.

For the avoidance of doubt, the Purchaser shall be entitled to direct any Group Company to carry out or omit any act or measure, if and to the extent such act, measure or omission complies with the Relevant Management Standards, subject to the second paragraph of clause 13.5 in connection with clauses 13.2.1 through 13.2.14 which shall prevail.

13.7	If Purchaser is in breach of any of its obligations set forth in clauses 13.5 and 13.6, any effects resulting from such breach shall be disregarded for the purposes of preparing the Reference Date Accounts and the Financial Statement (and in particular calculating the Reference Date Cash, Reference Date Debt and Reference Date NWC).

15

---

Furthermore, any expenses, costs, losses, lost turnover and/or amounts transferred by the Company or any Group Company to an entity other than a company of the Group which (i) are referred to in clauses 9.3 lit b, d, e, g and h, (ii) have been incurred by a Group Company in the Reference Date Period due to any acts, measures or omissions of the Group Companies that are based on an explicit instruction by the Purchaser (either directly vis-à-vis the managing directors of the relevant Group Company or - if an advisory board of a Group company exists and is capable of directing the managing directors of such Group Company (which the Parties agree is currently not the case) - indirectly through such advisory board) (it being understood that Sellers shall be obliged to evidence such instruction by the Purchaser), and (iii) would not have been incurred by such Group Company if the transactions contemplated under this Agreement had not taken place (i.e. if Closing had not occurred), shall be disregarded for the purposes of preparing the Reference Date Accounts and the Financial Statement.

For the avoidance of doubt, the Reference Date Cash, Reference Date Debt and Reference Date NWC shall be as determined in the Final Reference Date Accounts and the Final Financial Statement, i.e. any dispute between the Parties in relation to whether or not respective effects have been adequately disregarded pursuant to this clause 13.7 shall be resolved in accordance with the procedure set forth in clause 7.5.

For the avoidance of doubt, clause 22.4 shall apply to any dispute between the Parties in relation to whether or not Purchaser is in breach of any of its obligations set forth in clause 13.5.

For the avoidance of doubt, Sellers shall have no rights and there shall be no legal consequences whatsoever in case of a breach by Purchaser of its obligations set forth in clause 13.5, other than those explicitly set out in this clause 13.7."
