accrued expenses.” Only financial assets and assets involved in the company’s business usage– relating solely to the purchase of the site, the development and operation thereof shall be stated as assets; intangible financial assets
and accounting conveniences may not be stated. The reference date balance sheet, as with the proforma accounts, shall not include any liabilities in connection with maintenance/repair and/or renovation. There are no repair and maintenance reserves.
Obligations existing at the Transfer Date to implement future input tax adjustments pursuant to § 15 a VAT Act must be stated as a liability under one total; the same applies to claims arising from an adjustment under to § 15 a VAT Act.
These reference date accounts and balance sheet, which must also be certified with regard to meeting the aforementioned audit requirements as defined in § 317 ff. Commercial Code, are binding on both Parties as the basis for the calculation of
the final purchase price to be made under § 4 Section 1 to 3, if and to the extent that there is no objection to the accounts and reference date balance sheet and audit report as at the Transfer Date. Any objection must be made in
writing within 10 (ten) banking days after the accounts and reference date balance sheet and audit report are remitted and must also be sent to the other party. It must describe the specific grounds and to what extent the accounts and reference date
balance sheet allegedly fail to accord with the rules in this Agreement. Figures must be given for the minimum and maximum amount of the difference claimed in the objection relating to the items concerned and the resulting conclusions for the
company’s shareholders’ equity per the balance sheet. 
  

	6.	[sic] If in the event of objection the Parties are unable to agree within a further ten (10) banking days, counting from receipt by the other party of an objection, on the
amount of the difference, then, on application by one party, the matter will be decided by a neutral auditor to be appointed by both sides jointly. 










 If the Parties cannot agree on a neutral auditor within one week after the application has been filed by
one party to appoint a neutral auditor, either party is entitled to ask the competent chamber of chartered accountants to appoint the neutral auditor. The neutral auditor shall decide the matter as an arbitrator with binding effect on all parties.
The neutral auditor must give all parties an opportunity to state their position before he makes his decision; an oral debate shall take place if requested by one of the parties. The neutral auditor must provide all parties with his decision
together with a written statement of grounds. §§ 91 ff. Code of Civil Procedure shall apply accordingly to the costs of the arbitration proceedings. In his role as arbitrator the neutral auditor shall also decide on the allocation of
costs, which shall be binding on all parties. 
  

	7.	As soon as the Parties have agreed on the final purchase price or this has been finally determined by the neutral auditor, the corresponding balance shall be payable by the
contractual party with the obligation to make payment to the other party in each case. 

  
 § 6 
 Seller’s warranties and conditions as per contract

  

	1.	Seller’s warranties 

  
 The Seller issues warranties to the Buyers in the form of a separate warranty as to the following facts: 
  

	 	a)	 The information in § 1 of this deed is correct. The shares sold are not pledged or attached 













	 	 
or otherwise encumbered by third party rights (including obligations to vote in a certain way, voting rights or rights to dividends) or by restrictions on
sale or disposal of any kind. The Seller and Euroareal Verwaltungsgebäude are limited liability companies duly established under German law, Euroareal Verwaltungsgebäude having nominal capital of €€25,000. The Seller is the sole
shareholder of Euroareal Verwaltungsgebäude. The information in the extract of the Commercial Register relating to the Seller and to Euroareal Verwaltungsgebäude corresponds to the actual facts. The Seller is fully entitled to conclude and
implement this Agreement and to dispose of the shares and no other duties under the shareholders’ agreement or other contractual duties binding the Seller or Euroareal Verwaltungsgebäude are breached as a result. There are no other third
party pre-emption or acquisition rights with respect to the shares. 


  

	 	b)	All capital contributions to the shares have been paid up in full and have not been repaid either in whole or in part; nor is there a duty to make subsequent payment.


  

	 	c)	No resolutions have been passed concerning Euroareal Verwaltungsgebäude on the appropriation of profits relating to the period following the Transfer Date and there has been no
payment or promise to make payment of advance distributions of profits that shall not arise until after the Transfer Date.

in particular not in the sense of §§ 291, 292 Stock Corporation Act; no resolutions to transform the company have been adopted nor any other
transforming measures taken, in particular pursuant to the rules in the Transformation of Companies Act nor are there any silent partnership agreements, sub-participations, loans with profit participation or similar agreements or options or similar
rights thereto. Nor is Euroareal Verwaltungsgebäude consolidated as part of an actual group. 


  
 The Buyers do, however, know that the Seller, Euroareal Beteiligungs GmbH and their associated companies and Euroareal Verwaltungsgebäude are one VAT
filing entity. Neither the Seller nor Euroareal Beteiligungs GmbH and their associated companies nor Euroareal Verwaltungsgebäude, however, have any VAT arrears. 
  

	 	e)	The shares sold represent the entire nominal capital of Euroareal Verwaltungsgebäude, the Seller is sole shareholder of Euroareal Verwaltungsgebäude, there are no third
party claims on any basis to acquire shares. 

  

	 	f)	No insolvency proceedings have been commenced either on the assets of Euroareal Verwaltungsgebäude or on the assets of the Seller. There has been no application to commence
such proceedings nor shall the same be commenced under law nor is the same otherwise imminent. Neither the Seller nor Euroareal Verwaltungsgebäude are insolvent or over-encumbered by debt. 











	 	g)	The shareholders’ agreement corresponds with the deed of incorporation dated 18 March 2004, which is attached as Attachment VI.1 to the Reference Document. There are no
further agreements or resolutions pursuant to the shareholders’ agreement. 

  

	 	h)	Euroareal Verwaltungsgebäude is the owner of the subject of purchase more particularly described in § 1 Section 3 including all buildings thereon, which will
be encumbered only by the land charges shown in § 1 Section 4; it is moreover also absolute owner of all other assets including all claims, bank balances and liquid assets which 

  
 i) are stated in the annual accounts or in the proforma accounts to
be prepared as at 30 September 2005, 
  
 ii) it has
acquired after 30 September 2005 or which 
  
 iii) it
requires to meet its contractual duties. 
  
 There are no third
party rights hereto. Acquisitions and disposals of assets have only been made in the due course of business. Title to the subject of purchase including all buildings thereon and the technical facilities and equipment is available to an extent that
enables Euroareal Verwaltungsgebäude to meet all lease obligations arising from the lease agreements attached as Attachment IV to the Reference Document. 
  

	 	i)	 Euroareal Verwaltungsgebäude has no holdings in any other companies, in particular it has no company or participation rights of any kind in any other
companies, 













	 	 
be they partnerships, limited liability companies or trading companies, nor is it bound by any corresponding shareholders’ agreements.



  

	 	j)	Euroareal Verwaltungsgebäude has of now only those existing or imminent liabilities that are shown in the balance sheet of Euroareal Verwaltungsgebäude attached as
Attachment VI. 2 and 3 to the Reference Document as at 31.12.2004 or in the proforma accounts to be prepared. All claims shown in the proforma accounts to be prepared or in the accounts and reference date balance sheet at the Transfer
Date are valued (collectible) at the stated amount. 

  

	 	k)	The annual accounts of Euroareal Verwaltungsgebäude as at 31 December 2004 and the proforma accounts to be prepared are in accordance with the regulations of the
Commercial Code and the principles of proper accounting and reporting ensuring the continuity of the reporting and valuation, the accounts are complete and accurate and they are a true reflection of the assets and income position of Euroareal
Verwaltungsgebäude; nor is there any reason to fear a downturn in the asset and income position. All reserves, value adjustments and similar items in the balance sheets of the accounts that decrease assets or increase liabilities (with the
exception of building-related repair and maintenance reserves or reserves for subsequent payments of operating costs) have been accurately and fully determined and stated. 











	 	l)	Euroareal Verwaltungsgebäude has paid or retained and paid over in accordance with its statutory obligations all taxes and duties and, where not paid or paid over, has made
reserves in the balance sheet of the annual accounts, the proforma accounts and in the reference date accounts for future taxes and duties thus reducing its equity. In addition, it has made and submitted all necessary declarations to the tax
and other authorities at the proper time, completely and truthfully. There are no tax assessments relating to Euroareal Verwaltungsgebäude that have not been settled. 

  

	 	m)	Euroareal Verwaltungsgebäude has not made any public or covert profit distributions. All payment relationships with associated companies bear comparison with third party
relationships and otherwise too meet all preconditions under tax law for acceptance. 

  

	 	n)	The refinancing undertaken in 2004 and 2005 (Debeka and CSFB) of the land and buildings owned by Euroareal Verwaltungsgebäude result in no tax liabilities, in particular no tax
liabilities based on hidden profit distributions. 

  

	 	o)	The invoicing by or to third parties, including for rent under leases, must be done to or by Euroareal Verwaltungsgebäude so as to comply with the statutory regulations of the

	 	p)	Within the context of letting real estate, particularly to IBM Deutschland, Euroareal Verwaltungsgebäude has elected a valid option under VAT law enabling it to treat the VAT

	 	q)	 Euroareal Verwaltungsgebäude has not applied for a change in status as defined in the US Federal Income Tax Acts, i.e. it has not applied pursuant to Treasury
Regulation Section 301-7701-3 (c) on Internal Revenue Service Form 8832 (Entity Classification Election); the current assessment of Euroareal Verwaltungsgebäude as defined in the US Federal Income Tax Acts is the one under Treasury
Regulations Section 301-7701-3 (b) (2). The company has no assets (nor did it in the past) other than the subject of purchase with the buildings thereon, the associated moveable assets (fixtures and fittings), cash in hand, bank balances
and claims such as claims to rental payment, arising from the current lease business; the company has no (nor did it in the past have any) shares, loans, debentures or other participation certificates nor has the company paid any advances to an
issuer of securities (including those of associated companies or tenants); nor is or was the company party to a lease for moveable assets, except for leases 













	 	 
affecting movables and property assets jointly and where less than 10% of the total rent is attributable to the movables (calculated according to the average
market value of the movables at the start and end of the financial year compared to the average market value of the subject of purchase including the movables at the start and end of each financial year); and Euroareal Verwaltungsgebäude now no
longer makes more than USD 20,000 income in a calendar year from sources other than rent and interest on bank balances.

	 	g)	The agreements concluded by Euroareal Verwaltungsgebäude are not as of now terminated. Nor are there any terminations by the party currently pending with regard to these
agreements nor are there any circumstances or grounds justifying such termination. There are no defaults with regard to these agreements.

	 	k)	Euroareal Verwaltungsgebäude and/or the Seller or a company associated with the latter two companies have not concluded any agreements which in the event of a change in

	3.	Other agreements 

  
 Seller and buyer further agree as follows: 
  

	 	a)	To the extent that claims against the seller from provisions for the protection of the capital stock of Euroareal Verwaltungsgebäude exist, the seller also accepts the
obligation to fulfil these claims, even in the context of this purchase contract. 

  

	 	b)	The seller is obligated to make up for a deficit not covered by shareholders’ equity as shown on the financial statement on the day of valuation, to the extent that such a
deficit exists. In this respect, to the extent that the seller had already made payments to Euroareal Verwaltungsgebäude prior to the effective date of the transfer, which lead to an increase in the bank balance shown in the financial
statements on the day of valuation, this bank balance is not to be considered an increase in the purchase price according to § 4 number 2 and number 3 upon the calculation of the final purchase price. 

  

	 	c)	In the case of a corresponding request by the buyer, the seller will declare his approval that the technical Due Diligence Report that he commissioned in the context of the

the transfer costs resulting from the creation of the respective report to which the buyer’s request relates.

corresponding reserves, or corresponding reserves in an insufficient amount. The seller is obligated to release Euroareal Verwaltungsgebäude and the buyer from all payment obligations, and to compensate for other disadvantages that result if
the independent guarantee promises included in § 6 Section 1 (d), (l), (m) and (n) are not applicable. § 8 Section 1 remains unaffected.

 § 10 
 Rights of withdrawal 
  

	1.	Right of withdrawal of the seller 

  
 The seller is entitled to withdraw from this purchase contract if the buyer is delinquent more than ten bank working days in the payment of the
preliminary purchase price, and if an extension of time provided to the buyer from the seller under threat of withdrawal in writing (by courier and - according to the requirements of Section 3 - by fax) of at least an additional ten bank
working days passes without success. 










	2.	Right of withdrawal of the buyer 

  
 The buyers (only collectively) are entitled to withdraw from this purchase contract by means of written declaration (by courier and by fax) to the extent
that the due-date implementation requirements according to § 5 Section 2 (i) to (iv) of this contract or the due-date implementation requirements according to § 5 Section 2 (i) to (iv) of the
contract executed today regarding Euroareal Mainz Produktionsgebäude Hechtsheimer Strasse GmbH are not completely fulfilled by 20 November 2005. In addition, the buyers (only collectively) are entitled to withdraw from this purchase
contract by means of written declaration insofar as they are simultaneously withdrawn (in a manner in which they are entitled) from the contract executed today regarding the Euroareal Mainz Produktionsgebäude Hechtsheimer Strasse GmbH within
the context of compensation for damages to be paid to the buyers. The buyer’s additional legal rights of withdrawal, namely due to the seller’s failure to comply with respect to guarantees, remain unaffected. 
  

	3.	Exercise of a right of withdrawal 

  
 The right to withdraw is to be exercised by means of written declaration (by courier and by fax) to the other party in each case, to the attention of the
notary public that the parties to the contract hereby irrevocably authorize both to receive the declarations regarding the threat to exercise the right to withdraw as well as to receive of the declaration of withdrawal. The declaration of withdrawal
is (initially) valid upon the notary republic’s receipt of the declaration delivered by courier. The faxed notices merely serve as information in advance for the parties; neither their receipt nor their absence is of importance for the 










 
effectiveness of a threat of withdrawal nor for the exercise of a right of withdrawal. The notary public is required to inform the other party in each case
regarding the threat and the exercise of a right of withdrawal; the failure to provide this information does not affect the validity of the delivered declarations. The rights of withdrawal of the parties to the contract expire if the respective
right of withdrawal has not been exercised within two months after information is obtained regarding the grounds for withdrawal. 
  
 § 11 
 Other obligations of
the parties 
  

	3.	Obligations of the seller 

  

	 	a)	The seller will be responsible for seeing that Euroareal Verwaltungsgebäude [Euroareal Administrative Buildings] will carry out its transactions only in the customary line of
business after the date of the acceptance of this document until the assignment of the company shares is effective. However, investment procedures require the buyers’ assent that they are not entitled to refuse for unrealistic reasons. Changes
to existing rental contracts and/or the execution of new rental contracts require the buyers’ consent, which are entitled to make a decision based on their own discretion. 

  

	 	b)	 After the day of acceptance of this document until the assignment of the company shares is effective, the seller is obligated to finalize no withdrawals, profit
participation rights or other financial transactions that encumber Euroareal Verwaltungsgebäude, to put no corresponding resolutions into effect, and to not demand their implementation after the 












 
point in time mentioned above or to carry out other actions with a similar effect, insofar as the actions mentioned relate to profits that arise after the
effective date of the transfer. 
  

	2.	Obligations of the buyers 

  
 The buyers are obligated to cause the Euroareal management to assign its claims to compensation for damages of any sort against IBU GmbH & Co. Real Estate KG
(compare Attachment 3 of the annual financial statement, Attachment VI. 2 of the reference document) when the assignment of the company shares to the seller takes effect. The liability of Euroareal Verwaltungsgebäude for the valuation and
existence of the claim is barred, and the seller hereby waives all claims of this type against Euroareal Verwaltungsgebäude, presuming this waiver. The same correspondingly applies for the claims controlled by § 2 Section 3
(III) and § 3 Section 3 to additional payment for increased prepayments for operating costs and payment claims of IBM Deutschland GmbH for savings of energy costs for the period of time until the effective date of the transfer.

  
 § 12

parties to the contract are obligated to replace the provision that is invalid or cannot be carried out with a provision that is valid and that can be carried out that corresponds as closely as possible with the spirit and the purpose of the
provision to be replaced. The same applies for an omission in the contract.

land registry of the Mainz District Court, von Weisenau pages 4443 and von Hechtsheim 9881, Section III, nos. 1 and 2 and on page 4443, no. 4, as well as a statement of affirmation from the notary public (no older than five business days) that no
other encumbrances than those listed in §1 Section 3 are registered in the land registry except the mortgage in favour of CSFB which is cited in §1 Section 3, nor any applications for the registration of

	 	ii)	expiration of the statutory prohibition of execution pursuant to Cartel Act (GWB) §41; 











	 	iii)	creation of a supplemental deed for this share purchase agreement comprising the splitting and conveyance (assignment) to the Buyers 2a) and 2b) of the shares hereby

	 	iv)	certified photocopies of an amendment of the charter of Euroareal Produktionsgebäude to the effect that its fiscal year ends on 31 October 2005, and that the profit
transfer and controlling agreement of 15 November 2004 is cancelled effective 31 October 2005 (at the latest); as well as a commercial registry extract for Euroareal Produktionsgebäude evincing the amendment to the charter and the
cancellation of the profit transfer and controlling agreement of 15 November 2004 effective 31 October 2005 at the latest. 

  

	 	v)	the occurrence of the conditions for maturity recited in §5 Section 2 (i) to (iv) of the purchase agreement over all shares of Euroareal Mainz
Verwaltungsgebäude Hechtsheimer Strasse GmbH (Exhibit 1 of master instrument of notary public Wolfgang Gruntkowski). 

  

	3.	 The notary is responsible for the determination of and notification with respect to the condition of maturity cited at §5 Section 2 (i); otherwise
the parties are mutually obligated to each other to cause without delay the fulfilment of the other conditions of performance stipulated in §5 Section 2. The Buyers are entitled (but not obligated) to waive in full or in part














	 	 
any and all said conditions solely by a written statement to the notary. If these conditions are not met by 30 November 2005, the Buyers are
entitled under §11 Section 2 to withdraw from this purchase agreement. 


  

	4.	The Seller hereby irrevocably instructs the Buyers to settle the balances owed by the Seller of Euroareal Produktionsgebäude including all interest and incidental expenses out
of the provisional sale price, which amounts are to be accounted against the sale price. The remaining amount is to be paid into an account of the Seller to be named later at Commerzbank Bank AG, Bad Homburg (Sort Code 500 400 00).


  

	5.	Timeliness of payment is determined by the date on which the payment is received by the party entitled to receive it. The Buyers go into default immediately if they do not pay on
time. In such case, a late payment penalty of 8% p.a. above the base rate is charged. 

  

	6.	The calculation of the provisional purchase price is based on the “Proforma financial statement” to be created for 30 September 2005. 


 
 The Seller will take care that, within 20 (twenty) calendar days after
the payment of the provisional purchase price, a financial statement including a balance sheet for the transfer date (hereinafter also “deadline balance sheet”) is created, which, pursuant to the provisions of the commercial code, is to be
created in accordance with the principles of proper bookkeeping and account balancing and with consistent methods of accounting and evaluation, and which serves for determining the purchase price. The provisional purchase price stipulated in §4
may be adjusted only within the limits established by that provision, i.e. in the event that changes occur in the items “bank deposits”, “receivables”, [and/or] “liabilities, reserves and accruals and deferred items”.
Only assets connected with the company’s business purpose – not including the real estate which is the subject of this sale, the development and the operation of the developed real estate – may be counted as assets; intangible assets
and accounting aids may not be counted. No liabilities in connection with maintenance/repair and/or renovation activities may be entered into the deadline balance sheet or the pro forma financial statement. Repair and maintenance reserves are not
entered. Obligations to correct input value-added tax pursuant to Value Added Tax Act (UstG) §15a 










 
which exist on the transfer date are to be entered in a total sum as a liability; the same applies to receivables from a correction pursuant to §15a
UstG. This deadline financial statement and deadline balance sheet, which will also be reviewed in light of the foregoing requirements following an audit within the meaning of Commercial Code (HGB) §317ff., are binding on both parties as the
foundation for the final purchase price calculation to be performed within the framework set forth in § 4 Sections 1 to 3, if and as long as no objections are made to the financial statement, deadline balance sheet, and audit report as
of the transfer date. Objections must be filed in writing within 10 (ten) banking days after the transmittal of the financial statement and deadline balance sheet along with the audit report. They must be directed to the other party respectively.
They must set forth the individual grounds regarding the extent to which the financial statement and deadline balance sheet are allegedly out of compliance with the provisions of this agreement. The minimum and maximum differential amount asserted
on the basis of the objection in relation to the affected items and the resulting consequences for the company’s balance-sheet equity capital must be quantified. 
  

	7.	 In the event of an objection, if the parties are unable to agree on the differential amount within an additional period of 10 (ten) banking days to begin when the
other party 













	 	 
receives the objection, then at the request of one party a neutral auditor to be appointed by both sides jointly will decide it. If the parties are unable to
agree on a neutral auditor within one week after a party requests the appointment of a neutral auditor, then either party has a right to resort to the competent Wirtschaftsprüferkammer to have it appoint the neutral auditor. The neutral
auditor will decide as an arbitrator, and said decision will be binding on all parties. The neutral auditor must give each party an opportunity to explain its position before making a decision; at the request of a party an oral discussion will take
place. The neutral auditor must transmit its decision with the grounds therefore in writing to all parties. Code of Civil Procedure (ZPO) §§ 91 ff. applies to the costs of the arbitration proceedings. The neutral auditor, as the
arbitrator, also decides on the allocation of costs with binding effect as to all parties. 


  

	8.	As soon as the parties have agreed on the final purchase price or the neutral auditor has determined it as binding, the corresponding balance shall be paid by the party owing to the
other party respectively. 

  
 §6

 Additional purchase price (“earn-out”)/further leasing 
  

	1.	In so far as the sum total of the net actual rents to be detailed herein below which are paid by the lessees during an earn-out period of three years to be detailed herein below is
higher than €€7,005,000.00, the seller will receive an earn-out payment to be detailed below in addition to the purchase price stipulated in § 4 at the time stipulated in paragraph 5. This does not apply in so far as the
Buyers exercises their right under 











	 	 
paragraph 3 below to terminate prematurely the agreement made in this § 6 regarding the earn-out payment. 


  

	2.	A potential earn-out payment is determined as follows: 

  

	 	i)	The earn-out period of three years begins on the first calendar day of the month following the transfer date stipulated in § 3 Section 1 and ends upon the
expiration of 36 (thirty-six) months. 

  

	 	ii)	Net actual rents within the meaning of the agreements made in this § 6 are the actual rental incomes for the lease of rooms minus all leasing and development costs of
the lesser and all non-apportionable operating expenses and the costs of facility management, minus the legal value-added tax. The leasing and development expenses (particularly but not exclusively brokerage fees, development expenses and other
incentives) are apportioned, i.e. amortized, on the basis of an interest rate of 10% over the fixed term of the lease (beginning with the agreed commencement of rent payment). 

  

	 	iii)	 If, and to the extent that, the cumulative net actual rents paid by lessees over the earn-out period exceed €€7,005,000.00, and this occurs as a result of
lease agreements with a fixed term of at least seven years (to begin with the commencement of the earn-out period), which agreements were not yet in existence when this purchase agreement was concluded, the earn-out payment is calculated from the
amount above €€7,005,000.00 assessed for such leasing (“Surplus amount”). This amount is 













	 	 
converted to an annual basis, i.e. divided by 3 (three), and subsequently multiplied by 8.3 (eight point three). A sample calculation is enclosed as



  
 Attachment 2 “Sample calculation of
earn-out payment” 
  

	 	iv)	To the extent that the surplus above the amount of €€7,005,000.00 cited in paragraph 1 is based on leases with a term of less than 7 (seven) years, the amount of
the earn-out payment according to (iii) is limited to 50% of the actual effective rents owed during the term of the lease. 

  

	 	v)	If present or future tenants fail to extend their lease or fail to meet their rent payment obligations or other payment obligations, and as a result the net actual rents paid during
the earn-out period are below the threshold sum of €€7,005,000.00 according to paragraph 1, there will be no earn-out payment; in other words, only the payments which actually occur (and not the payments which are owed) during the
reference period (earn-out period) count toward the calculation of the earn-out payment. However, the special provision according to (vi) below remains unaffected; 

  

	 	vi)	 Animalised lease agreements which are at an advanced stage of negotiation at the end of the earn-out period and are finalized within three months thereafter also














	 	 
fall under the provisions of this § 6 and are to be treated as if they were finalized during the earn-out period. The earn-out payment to be paid
for these agreements is not due until the respective [lessee] has paid a full month’s rent for the first time. 


  

	3.	If the annual net actual rents actually paid do not increase by at least €€1,000,000.00 during the first 24 (twenty-four) months of the earn-out period, the Buyers can
withdraw from this § 6 through a unilateral written declaration to the Seller. In such case the Seller has no claim to [a continuing]earn-out payment. The maturity provision according to paragraph 5 below remains unaffected
hereby. 

  

	4.	The calculation of the earn-out payment is based on lease agreements with respect to which the lesser can opt for value-added tax. If this is not possible, the Seller must
compensate the Buyers for any losses and other financial detriments it suffers with a lump sum payment to be paid by the Seller concurrent with the finalization of the lease agreement. To the extent that the settlement is offset by additional rents
to be paid by the lessee, these rents are fully excluded from the calculation of the earn-out payment. 

  

	5.	The Buyers promise to calculate the earn-out payment within one month after the expiration of the earn-out period and to transmit the calculation to the Seller. This calculation is
binding on the Seller if it does not object within 10 (ten) banking days. In the event of an objection, the procedure stipulated in § 5 Section 6 is to be applied accordingly. The earn-out payment is due and payable as soon as the
parties agree to its amount, or the neutral auditor determines its amount as binding. 











	6.	The Seller will itself and/or through companies affiliated with it acquire additional tenants for the purchase property and in particular use best efforts to utilize its business
relationships with local and regional officials for such purpose, and will use sustained efforts to bring about the further development of the purchase property as a technology centre that is integrated into the surrounding regions. This will entail
the activation, use, and optimisation of the synergies offered by the high-tech, medical tech, biotech, and pharmaceuticals companies which are already located on the purchase property. The Buyers alone have sole discretion to decide on the
concluding of lease agreements with tenants suggested by the Seller. 

  
 § 7 
 Guarantees and quality agreements of the Seller 
  

	1.	Seller’s guarantees 

  
 Through this independent guarantee, the Seller warrants to the Buyers the following facts: 
  

	 	a)	The statements in § 1 of herein are true. The shares sold have been neither given nor taken in pledge nor are otherwise encumbered by the rights of third parties
(including voting obligations, voting rights or profit sharing rights) or by restraints on alienation or disposition of any kind. The Seller and Euroareal Produktionsgebäude are duly established limited liability corporations under German law;
Euroareal Produktionsgebäude has a registered capital of €25,000.00. The Seller is the only shareholder of Euroareal Produktionsgebäude. The information in the commercial registry extract regarding the Seller and Euroareal
Verwaltungsgebäude corresponds to the actual circumstances. The Seller has an unlimited right to make and execute this agreement and to dispose of the shares, nor do said actions result in the breach of any duties under the partnership
agreement or other contracts 











	 	 
to which the Seller or Euroareal Produktionsgebäude is bound. The shares are not subject to any rights of pre-emption or acquisition of third parties.



  

	 	b)	All contributions for the shares have been fully paid and have been neither wholly nor partly reclaimed; nor is there any duty to make subsequent contributions.


  

	 	c)	No profit allocation resolutions regarding Euroareal Produktionsgebäude which relate to the period after the transfer date have been passed, and no advance payments of profits
which will not accrue until the transfer date have been made or promised. 

  

	 	d)	 There are no company-transfer agreements of any kind with Euroareal Produktionsgebäude and its affiliates, i.e. shares thereof, particularly not within the
meaning of Stock Corporations Act (AktG) §§§ 291, 292; there have been no reorganization resolutions passed or any other measures encompassing reorganization, particularly pursuant to the Law on the 













	 	 
Transformation of Companies (UmwG), nor any existing silent partnership agreements, sub-partnerships, profit participation loans or other agreements, nor
options or similar rights thereto. Euroareal Produktionsgebäude is not a member of an actual group of affiliated companies. 


  
 However, the Buyers are aware that a value-added tax group exists among the Seller, Euroareal Beteiligungs GmbH and its affiliates, and Euroareal
Produktionsgebäude. But no VAT arrears exist either on the part of the Seller, Euroareal Beteiligungs GmbH and its affiliates, or Euroareal Produktionsgebäude. 
  

	 	e)	The shares sold constitute the entire registered capital of Euroareal Produktionsgebäude; the Seller is the sole shareholder of Euroareal Produktionsgebäude; there are no
third-party claims of any kind whatsoever to the acquisition of shares. 

  

	 	f)	Bankruptcy proceedings have not been instituted in relation to the assets of Euroareal Produktionsgebäude or the Seller’s assets. There has been no petition to institute
such proceedings, nor is there any valid legal requirement that they be instituted, nor are they imminent for any other reason. Neither the Seller nor Euroareal Produktionsgebäude is insolvent or overindebted. 

  

	 	g)	 The partnership agreement corresponds to the certificate of incorporation dated 18.03.2004 which is provided in Attachment 













	 	 
VII.1 as the reference document. There are no other agreements or resolutions relating to the partnership agreement. 


  

	 	h)	Euroareal Produktionsgebäude owns the purchase property described in detail in § 1(3) including all buildings thereon; the only encumbrances on said property are
those recited in § 1(4); Euroareal Produktionsgebäude is also the absolute owner of all other assets including all claims, credits, and liquid assets, which 

  

	 	i)	are included in the annual financial statement or in the “pro forma financial statement” per 30 September 2005, 

  

	 	ii)	it has subsequently acquired after 30 September 2005, 

  

	 	iii)	it needs in order to fulfil its contractual duties. 

  
 No third party has rights thereto. Additions to and deductions from the property assets have occurred only in the ordinary course of business. The
ownership of the purchase property, including all buildings and technical equipment and facilities thereon, is disposable in a scope which allows Euroareal Produktionsgebäude to fulfil all obligations with respect to leasing under the lease
agreements enclosed in Attachment V. of the reference document. 
  

	 	i)	Euroareal Produktionsgebäude holds no interests in other companies; in particular, it holds no partnership rights or participation rights as to other companies, be they
partnerships, corporations, or commercial companies, and is not bound by any partnership agreements accordingly. 











	 	j)	Up to the present day, the only existing of impending liabilities of Euroareal Produktionsgebäude are those cited in the balance sheet of Euroareal Produktionsgebäude from
31.12.2004 which is enclosed in Attachment VII.2 of he reference document and those cited in the “pro forma financial statement” which will be created. All receivables declared for the transfer date in the “pro forma
financial statement” to be created or in the financial statement including the deadline balance sheet are recoverable (collectible). 

  

	 	k)	The annual financial statement of Euroareal Produktionsgebäude as of 31 December 2004 and the “pro forma financial statement” to be created comply with
the provisions of the commercial code and the principles of standard bookkeeping and account balancing and employ consistent balancing and evaluation methods; the financial statements are complete and accurate, they give an accurate picture of the
asset and earnings situation of Euroareal Produktionsgebäude; there is no reason to fear possible adverse changes of the asset and earnings situations. All reserves, value corrections and suchlike which constitute asset reducing or liability
increasing items – with the exception of reserves for building related repairs and maintenance or reserves for the additional payment of operating expenses – have been calculated and disclosed accurately and completely.












	 	l)	Euroareal Produktionsgebäude has paid, or has withheld and remitted, all taxes and public charges and, to the extent not paid or remitted, has deferred said taxes and charges
in the balance sheet of the annual financial statement, the balance sheet of the “pro forma balance sheet” to be created, and the deadline financial statement, for future taxes and charges as well, and has reduced its equity capital
accordingly. Furthermore, it has given and filed on time, completely, and truthfully all declarations required by tax and other government authorities. There are no outstanding tax assessment notices in relation to Euroareal Produktionsgebäude.


  

	 	m)	Euroareal Produktionsgebäude has not undertaken any open or hidden dividends. All service relationships with affiliated companies bear comparison with external relationships
and otherwise satisfy all tax conditions for recognition. 

  

	 	n)	The refinancing actions (Debeka and CSFB) of the real estate holdings of Euroareal Produktionsgebäude in 2004 and 2005 did not result in any tax liabilities, particularly tax
liabilities on the basis of hidden dividends. 

  

	 	o)	All invoices to or from third parties, in particularly for rents pursuant to leases, have been presented by or to Euroareal Produktionsgebäude in such a way as to comply with
the legal provisions of the Value-Added Tax Act, and particularly the input VAT as of the date claimed or the date used has been deducted in compliance with legal requirements. 











	 	p)	In leasing the purchase property, Euroareal Produktionsgebäude has elected an effective VAT option that allows all the VAT stated in the invoices that list it as the recipient
of the corresponding deliveries or other services to be treated as refundable or offsettable input tax. 

  

	 	q)	 Euroareal Produktionsgebäude has not filed a petition to change its status within the meaning of the United States federal income tax code, namely any petition
according to Treasury Regulation Section 301-7701-3(c) on Internal Revenue Service Form 8832 (Entity Classification Election); currently the interpretation of Euroareal Produktionsgebäude within the meaning of the US Federal Income Tax
Code is the interpretation according to Treasure Regulations Section 301-7701-3(b)(2). The company has no other assets (in the past either) other than the purchase property with the buildings, annexed personal property (fittings and fixtures),
cash in hand, bank deposits and claims such as claims for rent which derive from the running leasing business; the company does not have (and never had in the past) any stocks, loans, debenture bonds, or other dividend papers, nor has the company

of personal property and real property where the rents for the 













	 	 
personal property amounts to les than 10% of the total rents (calculate on the basis of the average market value of the personal property at the beginning
and end of the fiscal year relative to the average market value of the real property including the personal property at the beginning and end of the respective fiscal year); and Euroareal Produktionsgebäude also has not earned more than USD
20,000.00 in income in a calendar year from sources other than rents and interest on bank deposits. 


  

	 	r)	Euroareal Produktionsgebäude has not entered an employment relationship with any person, its managers not excepted. 

  

	 	s)	The mortgages cited in § 1 Section 4 and § 5 Section 2 (i) secure the liabilities of Euroareal Produktionsgebäude only, i.e. not the
liabilities of third parties or affiliated companies. 

  

	 	t)	Euroareal Produktionsgebäude has satisfied fully and finally all obligations resulting from the loan granted by Debeka Bausparkasse AG. Euroareal Produktionsgebäude has no
further liabilities as a result of, or in connection with, loan agreements, particularly vis a vis the Seller. Furthermore, Euroareal Produktionsgebäude satisfied all liabilities resulting from the loan agreement with CSFB by the transfer date.


  

	 	u)	 The purchase property is free of obligations to construct or maintain, unrecorded easements, and no restrictions according to the law of neighbours except such














	 	 
encumbrances as are contained in § 1 Section 4 in conjunction with Attachments I.7-8 and I.11-12 of the reference document.



  

	 	v)	In the buildings standing on the purchase property, there is no asbestos requiring immediate removal pursuant to the respective official regulations. 

  

	 	w)	The plan for voluntary soil air decontamination enclosed as Attachment IX will be completed by 30.06.2006. 

  

	2.	Quality agreements 

  
 The Seller further warrants, with respect to an agreed quality for purposes of the Seller’s legal or contractual warranty liability, that the
following statements are true as of today and will be true as of the transfer date: 
  

	 	a)	As of the transfer date, all development assessments pursuant to Building Code (BauGB) §§§ 123 ff. and other public charges pursuant to the Municipal Charges Act and
the corresponding municipal codes, as well as cost reimbursement claims, amounts for discharge and compensation, and other public assessments due for the currently existing development of the purchase property for the uses on which this purchase
agreement is based, have been paid in full; the same is true of the connection to the public water and sewer supply and the power supply. 











	 	b)	For all buildings on the purchase property, all the required building and use permits have been obtained unconditionally and indefinitely, including parking lot documentation and
all other official permits, and all obligations required in the permits granted have been met. This also applies to the directions/obligations under the current fire code and corresponding official regulations. The units that are still rentable in
buildings 01 and 11 correspond to the requirements for the use of clean rooms by high-tech companies, medical tech companies, biotech companies, and pharmaceutical companies. 

  

	 	c)	Euroareal Produktionsgebäude has, and had in the past, insurance which it is contractually required to hold; it was and is further insured, in the amounts cited in Attachment
II of the reference document, against risks against which this kind of company, exercising ordinary care, is usually insured. 

  

	 	d)	Euroareal Produktionsgebäude is not in arrears with any premium payment, and there do not exist any circumstances that call into question the continuation of the insurance.
Copies of the corresponding insurance policies are enclosed as Attachment II.3 and 4 to the reference document. Euroareal Produktionsgebäude has not filed any claims or requested any coverage commitments in relation to the insurance policies.


  

	 	e)	 Except for the agreements cited in § 1, copies of which are enclosed in attachment to the reference document, in the versions cited therein and with
contents as they 













	 	 
appear in the reference document, and except for standard agreements on proper management of the real estate, Euroareal Produktionsgebäude is not bound
by any agreement, particularly not the following: 


  

	 	i)	agreements with the Seller, companies affiliated with the Seller, or relatives with in the meaning of the Fiscal Charges Regulations (Abgabenordnung) § 15,


  

	 	ii)	rental and lease agreements over real property, 

  

	 	iii)	employment, hiring, and service agreements of any kind except for management agreements, but the latter without remuneration or buy-out obligations, 

  

	 	iv)	support commitments and promises to share profits; 

  

	 	v)	collective labour agreements and plant agreements, 

  

	 	vi)	loan agreements, 

  

	 	f)	The agreements enclosed with the reference document are enclosed in full; no amendments, additions, or collateral agreements have been made, 

  

	 	g)	The agreements concluded by Euroareal Produktionsgebäude have not been terminated up to the present day. Terminations of these agreements by the other party are not imminent at
the present time, and there exist no circumstances or reasons that would justify such termination. No defaults in performance have occurred with respect to these agreements. 

  

	 	h)	All rental agreements of Euroareal Produktionsgebäude (Attachment V of reference document) with a remaining term of more than one year satisfy the formal requirements per
German Civil Code §§§ 550, 126. 









	 	i)	There exist no advance disposals of rent, no advances on building costs subject to refund by the Seller, and/or no other refundable advances by tenants. 

  

	 	j)	There are no collateral agreements with tenants, neighbours, or government officials which are not apparent from the attachments to the reference document.

the Seller or Euroareal Produktionsgebäude been threatened with such proceedings. 









	 	o)	The Seller assumes liability to the Buyers for damages, detriments and expenses resulting from the existence of environmental contamination of the ground water, soil, and/or
buildings, which has occurred hitherto or may yet occur due to their present condition, for which claims may be lodged against the Buyers or Euroareal Produktionsgebäude. The liability includes obligations or claims of third parties under civil
law and public law. To the extent that stipulations are made in the purchase agreement (Attachment IV 2 to reference document) respecting environmental damage which was established hitherto, the Seller is liable only to the extent that measures must
be taken in order to guarantee that the use of the purchase property and buildings and building structures by the owner and the tenant at the time is not impaired or at risk of a diminution of rent. 

  

	 	p)	Recourse within the meaning of the Federal Soil Protection Act § 24(2) against Euroareal Produktionsgebäude or the Buyers is excluded; to the same extent the Seller waives
its claims against the Buyers and Euroverwaltungsgebäude as a result of or in connection with environmental impact. 









	3.	Other agreements 

  
 The Seller and Buyers further agree as follows: 
  

	 	a)	To the extent that claims exist against the Seller on the basis of provisions for the protection of the registered capital of Euroareal Produktionsgebäude, the Seller
undertakes, by this purchase agreement also, that it will satisfy said claims. 

  

	 	b)	To the extent that the deadline financial statement discloses a deficiency which is not covered by the equity capital, the Seller promises to settle said deficiency. To the extent
that the Seller has made payments to Euroareal Produktionsgebäude before the transfer date for this purpose, which add to the bank deposits stated in the deadline financial statement, the final purchase price will not be increased due to this
bank deposit when it is calculated per § 4 Sections 2 and 3. 

  

	 	c)	Upon receiving a corresponding request from the Buyers, the Seller will declare its consent to the technical due diligence reports which are arranged by CFSB in connection with the
financing it provides being “addressed” to the Buyers as well, so that the Buyers may bring potential claims against the author of the report. In the event of such a request, the Buyers must pay 50% of the expenses for creating the
respective report to which the Buyers’ request relates and the transmittal expenses. 

  

	 	d)	The Buyers take notice of the Seller’s intent that the water house which is operated by Euroareal Produktionsgebäude in building 02/03 on the purchase property of [sic]
should undergo economic optimisation.

additionally incurred by Euroareal Produktionsgebäude for this purpose are assessable.

than ten banking days, and an additional period of at least another ten banking days, which the Seller grants the Buyers in writing (per courier and, as provided in paragraph 3, by fax) under threat of withdrawal, expires without results.

  

	2.	Seller’s right of withdrawal 

  
 The Seller has a right (only jointly) to withdraw from this purchase agreement by written declaration (per courier and telefax), provided that the
conditions of maturity-performance pursuant to § 5 Section 2(i) to (iv) of this agreement or the conditions of maturity-performance per § 5 Section 2(i) to (iv) of the agreement on Euroareal Mainz

parties hereby irrevocably authorize to receive both the declarations warning that withdrawal rights will be exercised and the withdrawal declaration itself. The withdrawal declaration is effective (only) upon receipt of the declaration by the
notary by messenger. Fax messages serve only for informing the parties involved neither its receipt nor its omission is material to the effectiveness of a warning of withdrawal or the exercise of withdrawal rights. The notary is responsible for
notifying the other party immediately of the warning and the exercising of rights of withdrawal; the omission of such notice will not affect the validity of the declarations. The rights of withdrawal of the parties are extinguished immediately two
months after the date on which notice of the grounds of withdrawal is received if the respective withdrawal rights have not been exercised by then.

 Other duties of the
Seller 
  

	1.	The Seller will take care that Euroareal Produktionsgebäude conducts its businesses exclusively in the ordinary course from the date of the adoption of this document until the

Amendments to existing lease agreements and/or the concluding of new lease agreements require the approval of the Buyers, who are entitled to decide at their
own discretion. 


  

	2.	The Seller promises not to resolve to undertake, from the date on which this document is adopted until the assignment of shares goes into effect, any withdrawals, profit sharing
rights, or other financial transactions to the debit of Euroareal Produktionsgebäude, to carry out any potential corresponding resolutions, or, after the above referenced date, to demand their execution or to take other actions with a similar
effect, to the extent that said actions relate to profits which arise after the transfer date. 

  
 § 13 
 Severability 
  
 If a provision of this agreement is invalid or is or becomes unperformable, the validity of
the agreement is otherwise unaffected. The parties promise that the invalid or unperformable provision will be replaced with a valid and performable provision, which best corresponds to the spirit and purpose of the original provision. The same
applies to loopholes accordingly. 
  
 § 14 

Final provisions 
  

	1.	 This purchase agreement is recorded together with the purchase agreement covering all shares of Euroareal Mainz Verwaltungsgebäude Hechts-Heimer 













	 	 
Strasse GmbH in a master document. The costs for recording are allocated to the two purchase agreements according to the ratio of the amounts cited in
§ 4 Section 2 paragraph (1). The costs thus allocated to the Buyers, in addition to the costs for the addendum cited in § 2 Section 1, are borne by the Buyers in proportion to their purchase shares. All costs for
clearing encumbrances, including clearing encumbrances on the purchase property pursuant to this agreement, are borne by the seller. Otherwise, unless otherwise agreed, each party bears the costs and taxes that have accrued, or will accrue, to it.

 § 15 
 Rights, jurisdiction

 § 16 

Miscellaneous and instructions 
  

	1.	The Buyers will instruct Euroareal Produktionsgebäude about the change of shareholders pursuant to the Law on GmbH’s § 16. 

  

	2.	The notary has further made reference to the liability provisions of the Law on Limited Companies, particularly to the fact that the buyer of a share assumes unlimited liability for
unpaid cash contributions and potentially for deficiencies resulting from inadequate contributions in kind of the Seller and all other shareholders; similarly for refunding potentially prohibited repayments back into the registered capital and for a
potential land purchase tax liability. 

  

	3.	The parties are aware that a bona fide acquisition of shares of a business is impossible. The stated participation ratios, which are based on statements of the participants, are
verifiably by the notary only to a limited degree.

	5.	All approvals become effective when received by the notary.

 II. 
 Modification of individual contractual conditions 
  
 The Seller and the Purchasers hereby agree to the following changes in the above-mentioned set of contracts: 
  

	1.	In accordance with § 2 Section 2 c), the following insertion is made as d) in both the Administrative Building Purchase Contract and the Production Building Purchase
Contract: 

  
 “In the implementation of this
Purchase Contract, the Seller provides an undertaking, with payment of the amount due on execution as a condition precedent, to cooperate in the dismissal of the present Managing Director and the appointment of one or a number of new managing
directors.” 
  

	2.	Furthermore, the following insertion is made as e) in § 2 Section 2 of the Production Building Purchase Contract: 

  
 “The Purchasers intend to have the Clean Room and what is termed the
‘Water House’ located in Building 02/03 operated and managed by another company. Within the context of what is legally possible, the Seller undertakes to take steps to ensure that in the execution of this Purchase Contract, the Euroreal
Produktionsgebäude (Production Building) will cooperate in all measures to be carried out in connection with this.” 
  

	3.	§ 2 Section 7 of the Administrative Building Purchase Contract and § 2 Section 6 of the Production Building Purchase Contract respectively, are reworded as
follows: 

  
 “This Purchase Contract is to be
implemented on 31 October 2005 at 24:00, subject to the arrangements in § 5.2.” 










	4.	In accordance with § 4 Section 3, the following § 4 Section 4 is to be inserted in the Administrative Building Purchase Contract and in the Production Building
Purchase Contract respectively: 

  
 “The
Seller provides an undertaking to submit by 25 October 2005 a set of annual accounts for the year to 31 December 2004 and the “Proforma Statement” as per 30 September 2005 still to be produced. The “Proforma
Statement” as per 30 September 2005 must take into full account all of the existing obligations in respect of CSFB and all other obligations and contingent obligations, in particular in respect of taxes. This applies correspondingly for
the annual accounts for the year to 31 December 2004. 
  
 The Purchasers are entitled to check for themselves the annual accounts for the year up to 31 December 2004 and the “Proforma Statement” as per 30 September 2005 or to have them audited at their own cost by a business
auditing company to be nominated by themselves. If the Purchasers should have any reservations about the provisional purchase price calculated on the basis of these accounts, then the difference between the provisional purchase price calculated as
by the Seller and that calculated by the Purchasers, having taken into account their reservations, is to be paid into a third-party account of the authenticating Notary, the details of which account are still to be notified. As soon as the parties
have reached agreement on the final purchase price after submission of the statement for the reference date, or the final purchase price has been bindingly calculated by the neutral auditor through application of the procedure as per § 5
Section 8 [erroneously designated as § 5 Section 6 in the Administrative Building Purchase Contract in the deed of the authenticating Notary dated 22 September 2005, Deed No. 1577 for the year 2005], then the amount paid
into the third-party account is to be 










 
paid out to the parties proportionately to their respective entitlements. The payment of the final purchase price remains unaffected by the above-mentioned
arrangement. 
  
 The annual accounts for the year up to
31 December 2004, to be submitted by the Seller by 25 October 2005, shall represent those accounts on which the Seller’s guarantees shall be based. In this connection, the parties shall make it clear that the circumstances of which
the Purchasers have become aware within the context of their due diligence activities shall in no way restrict these guarantees from the Seller. To this extent, § 254 of the BGB / Civil Code is excluded.” 
  

	5.	The Purchasers are entitled to withdraw from these contractual arrangements if, by 25 October 2005, the Seller has not submitted the accounts stipulated in Point 4. (by fax or
by e-mail to Deloitte & Touche, Frankfurt). In this case, the costs of notarial authentication will be borne by the Seller, this without prejudice to any further claims on the part of the Purchaser. 

  

	6.	§ 5 Section 4 of the Administrative Building Purchase Contract is reworded as follows: 

  
 “The Seller hereby irrevocably instructs the Purchaser to settle by means of offsetting against the purchase price the
following: 
  

	 	a)	the balances owed by the Purchaser to Euroreal Administrative Building, inclusive of all interest and accessory claims, and 

  

	 	b)	 the claim held by Debeka Bausparkasse AG to the amount of € 3,627,889.78 (in words: three million, six hundred and twenty-seven thousand, eight hundred
and eighty-nine euro and 78 eurocents), 













	 	 
From the remaining amount, a deduction to the amount of € 800,000.00 (in words: eight hundred thousand euro) is to be made. The Purchasers are
entitled to settle from this amount by way of offsetting against the purchase price, all taxes and levies owed by Euroreal Verwaltungsgebäude and/or Euroreal Produktionsgebäude along with other debts not, or not completely, taken into
account in the “Proforma Statement” as per 30 September 2005 to be produced for each of the companies, these taxes and levies relating to the period up to the transfer reference date and for which the Seller has not in the respective
“Proforma Statements” as per 30 September 2005 shown any reserves with the effect of reducing equity capital. Any amount remaining after these debts are settled is to be paid into the Seller’s account as detailed in the next
sub-paragraph, after that point in time at which the corresponding taxes or levies, or amounts of liability, have been determined finally (and materially) to be legally valid in respect of Euroreal Verwaltungsgebäude or Euroreal
Produktionsgebäude, as the case may be. 


  
 The Seller is entitled to request that the retained amount of EUR 800,000.00 be paid out on submission of a tax and levies statement (also) subject to inspection, in respect of the two companies being sold off here, conditionally on the
Seller providing for the Purchasers a directly liable banker’s guarantee without limit of time, issued by a financial institution subject to German banking supervision. This guarantee shall expire as soon as the statements on taxes and levies
become final and materially legally valid. 
  
 The amount
remaining after deduction of the amounts specified in the two preceding sub-paragraphs is to be paid 










 
into an account of the Seller still to be notified, held with Commerzbank AG, Bad Homburg (Sort Code 500 400 00), subject to the conditions set out in §
4 Section 4.” 
  

	7.	§ 5 Section 4 page 2 of the Production Building Purchase Contract is reworded as follows: 

  
 “The remaining amount is to be paid into an account of the Seller still to be notified, held with Commerzbank AG, Bad
Homburg (Sort Code 500 400 00), subject to the conditions set out in § 4 Section 4.” 
  

	8.	The Purchasers provide the Seller with an undertaking that they will produce, submit and, if relevant, appeal in respect of the annual accounts for 2005 and tax declarations for the
period of time up to the transfer reference date. The Purchasers are obliged to impose the above-mentioned obligation on any subsequent legal successor. In the event of differences of opinion, the matter will be decided by the neutral auditor to be
nominated jointly by the two sides. The stipulated arrangement for the binding calculation of the definitive purchase prices shall apply correspondingly. 

  
 III. 
 Seller’s affirmation 
  
 The Seller provides the following
affirmation: 
  
 The Control Contract and Profit Transfer Agreement concluded on
15 November 2004 between Euroreal Holding Projekt Mainz Hechtsheimerstrasse GmbH and Euroreal Mainz Verwaltungsgebäude Hechtsheimerstrasse GmbH (designated erroneously in the last-mentioned contract as “Euroreal Mainz
Verwaltungsgebäude GmbH”) was cancelled on 










 
31 December 2004. A copy of the Cancellation Agreement is attached to this deed. It fully and correctly sets out the agreements reached between the
parties on this date. The above-mentioned Control Contract and Profit Transfer Agreement was subject to a condition precedent which did not come into effect. Accordingly, the above-mentioned Control Contract and Profit Transfer Agreement of
15 November 2004 remains in force to the present day, along with the arrangements stipulated therein. 
  
 IV. 
 Miscellaneous 
  
 All formal approvals shall become effective on being received by the authenticating notary.

  
 The parties involved expressly confirm that under their own responsibility
they have had the above-mentioned set of contracts checked by their legal advisers, from the commercial point of view and also, in particular, in respect of fiscal law and the law on contracts.

 Cancellation Agreement

  
 between the limited liability company operating under the business
name of Euroreal Holding Projekt Mainz Hechtsheimerstrasse GmbH with its head office in Cologne, 
  
 - as the Controlling Company - 
  
 and the limited liability company operating under the business name of Euroreal Mainz Verwaltungsgebäude GmbH with its head office in Cologne, 
  
 - as the Controlled Company - 
  
 The Control Contract and Profit Transfer Agreement concluded on 15 November 2004 is cancelled on substantive grounds due to the intention to sell off the Controlled
Company under the condition precedent of transfer of the shares in the company. This breaches no rights of any third parties. 
  
 If any individual provisions in this Contract should be, or become, invalid, this in no way affects the validity of the Contract as a whole. Both Parties to the Contract
shall replace the invalid provision with another provision which as closely as possible approximates the commercial intent of the invalid provision.
