Instead, they have agreed to replace the statutory system and provide for an independent catalogue of specific rights of the Purchaser individually agreed as set forth in this Clause 4. The representations and warranties of each Seller pursuant to this Clause 4.1 shall not constitute guarantees (Garantien) within the meaning of section 444 BGB, but shall constitute separate, independent obligations of a Seller and the scope and content of each representation and warranty of each Seller and any liability of a Seller arising hereunder shall be exclusively defined by the provisions of this Clause 4 and the remainder of this Agreement, which provisions form an integral part of the representations and warranties given by each Seller.

4.1.1 Subject to the limitations of liabilities and the explicit restrictions of certain legal rights, including certain caps agreed in this Agreement, each Seller severally represents and warrants to Purchaser in respect of itself and those Shares and Shareholder Loans sold by it hereunder only, by way of an independent guarantee (selbständiges Garantieversprechen) pursuant to section 311 paragraph 1 BGB, that the statements set out in this Clause 4.1.1 are true and correct as of the date hereof as well as of the Closing Date.

4.1.1.1 Each Seller which is a legal person has the full corporate power and authority to enter into this Agreement and to carry out the transactions contemplated hereby and such transactions have been duly authorised by all necessary corporate action on the part of such Seller. Each Seller which is a natural person is authorised and has capacity to enter

	into this Agreement and to carry out the transaction contemplated hereby and, to the extent the same is required, the consent under section 1365 BGB is attached in Schedule 4.1.1.1. This Agreement has been duly executed by or on behalf of each Seller and constitutes its binding obligations.
4.1.1.2	There is no action, suit, investigation or proceeding pending against, or to each Seller’s actual knowledge, as of the date hereof, threatened against or affecting, such Seller before any court or arbitrator or any governmental body, agency, official or other third party which in any manner challenges or seeks to prevent the transfer of the Shares or, where relevant, the Shareholder Loans.
4.1.1.3	The statements in Preamble (A) in respect of the Company are correct.
4.1.1.4	Each Seller is the owner of those Share(s) sold by it pursuant to Clause 2.1 or offered pursuant to the “Call Option”, and of that Shareholder Loan (if any) sold by it under Clause 2.3. On the Closing Date such Share(s) and Shareholder Loan will be unencumbered and free from any third parties’ rights, subject to the Releases becoming effective and save only to the extent the survival or creation of third party rights is caused (in whole or in part) by Purchaser or its financing sources, in particular if Purchaser creates new third party rights.
4.1.1.5	The statements in Schedule B are true and correct. The Company holds those and only those direct and indirect participations in the beta Group Companies shown in Schedule B. Subject to the Releases becoming effective and save only to the extent the survival or creation of third party rights is caused (in whole or in part) by Purchaser or its financing sources, in particular if Purchaser creates new third party rights, there are no encumbrances or any other third party rights, including rights to subscribe for any new shares or interest, affecting such shares and interest in the beta Group Companies.
4.1.1.6	The aggregate claims under the Shareholder Loans for principal and interest accrued thereon will as of the Closing Date be the amount of the Purchase Price for Shareholder Loans.

4.1.2 Subject to the limitations of liabilities and the explicit restrictions of certain legal rights, including certain caps agreed in this Agreement, each Active Manager severally represents and warrants to Purchaser by way of an independent guarantee (selbständiges Garantieversprechen) pursuant to section 311 paragraph 1 BGB, that to the Best Knowledge of the respective Active Manager, the statements set out in Schedule 4.1.2 are true and correct as of the date hereof and no Active Manager is, to the Best Knowledge of the respective Active Manager, aware that they will not be true and correct as of the Closing Date as anticipated to occur on 3^rd March 2006. “Best Knowledge” of the respective Active Manager within the meaning of this Agreement shall mean the actual knowledge (Kennen) of the Active Managers as of the date hereof and the knowledge they could have had (Kennen müssen), had the respective Active Manager observed the standard of care applicable to him taking account of their individual position and level of responsibility.

4.2 If any of the statements made by a Seller in Clause 4.1 above should be incorrect in whole or in part (a “Breach”), as applicable to each respective Seller, such Seller shall as a several obligor (Teilschuldner) following receipt of the respective written notice of claim by Purchaser:

4.2.1

restore the position to what it would have been if the Breach had not occurred (Naturalrestitution) within a reasonable time period, but no later than three (3) months after receipt of the respective notice of claim. If (a) such restitution is impossible, or (b) the Seller finally refuses (ernsthaft und endgültig verweigern) to make restitution in kind, Purchaser may claim compensation in money (Schadensersatz in Geld) under Clause 4.2.2 below before the expiry of the three (3) month period; or

4.2.2

subject to Clause 4.2.1, pay to Purchaser compensation in money (Schadensersatz in Geld) for the actual damages (unmittelbare Schäden) and foreseeable indirect damages (vorhersehbare mittelbare Folgeschäden) suffered by the Purchaser as a result of such Breach in accordance with the respective provisions of the BGB.

5.2.2

Purchaser fails to give Sellers the opportunity to remedy pursuant to Clause 4.2 within the agreed three (3) months time period, or fails to use all reasonable efforts to mitigate its loss, including — for the avoidance of doubt — any remedy available to any member of the beta Group under or in connection with the share purchase and transfer agreement with beta healthcare GmbH & Co KG dated 22 December 2003 (roll of deeds no. 188/2003 of the notary public Dr. Patrick Wamester, Basel) (“SPA 2003”) unless this is not reasonably expected to mitigate losses, provided that if and to the extent Purchaser proves that any non-compliance with this Clause 5.2.2 did not result in a higher obligation or liability of the Seller in question, Purchaser shall not be excluded from bringing a Purchaser’s Claim. Purchaser shall inform Sellers reasonably without undue delay after

-18-

becoming aware of any alleged incorrectness or incompleteness and no respective Seller shall be liable to the extent any damages are caused by a delay in the information to Sellers.

5.3 The liability of Sellers under or in connection with this Agreement shall be limited as follows:

5.3.1	The liability of Sellers under or in connection with this Agreement is several only (Einzel- und Teilschuldner).
5.3.2	Purchaser is entitled to a claim under or in connection with this Agreement (except for claims based on Clauses 4.1.1.6 and 7.4) only if any individual claim exceeds EUR 100,000.00 (in words: hundred thousand Euros), provided that a series of related claims (Serienschaden) shall be considered one claim for purposes of this Clause 5.3.2, (de minimis) (Freigrenze) and if the sum of all such claims exceeds EUR 1,000,000.00 (in words: one million Euros) in the exceeding amount only (Freibetrag).
5.3.3	For all claims under or in connection with this Agreement:

(a)	the maximum aggregate liability of the Sellers together under or in connection with the guarantees according to Clause 4.1.1 and in respect of any liability that may arise in relation to Clause 7.1.5 is the amount of the Total Purchase Price and, for the avoidance of doubt, for each Seller is that amount of the Total Purchase Price attributable to it;
(b)	the maximum aggregate liability of the Active Managers under or in connection with this Agreement, excluding only (i) the liability referred to under (a) above to which the cap under (a) above shall apply and (ii) the liability referred to under Clause 7.4 below to which the cap under Clause 7.4.9 shall apply, is 30 % (thirty percent) of that part of the Total Purchase Price which is attributable to the Active Managers i.e. EUR 3,600,611.65 (in words: three million six hundred thousand six hundred eleven Euro and sixty-five cents);

5.3.5 Subject to the further limitations as set forth in this Agreement, if more than one Seller is individually liable in respect of the same Purchaser’s Claim, the liability of each Seller in respect of such claim shall be the percentage of the Total Purchase Price attributable to that particular Seller.

5.4	Purchaser confirms that it has had access to information from and about the beta Group Companies and has satisfactorily completed a due diligence review prior to the signing of this Agreement. Consequently, the representations and warranties and indemnities given by each Seller are limited solely to those expressly set out in this Agreement and no other representations, warranties, indemnities or guarantees are given, or any liability assumed, by any Seller whether expressly, impliedly or by law. Any claim of Purchaser and any liability of a Seller under or in connection with this Agreement, including under Clause 4 or this Clause 5, but excluding under Clause 7.4 (tax indemnity), is further excluded if and to the extent to which facts or circumstances have been disclosed in this Agreement (including the Schedules). The same applies with respect to the other information provided to the Purchaser, its representatives or advisors in writing during the negotiations leading up to the execution and implementation of this Agreement attached hereto as Schedule 5.4, including the management presentations and question and answer sessions.
5.5	Any right of Purchaser to rescind or withdraw from this Agreement shall be excluded save as set out in Clause 8. Any claims and rights of Purchaser beyond the independent guarantees provided for in Clause 4 and the rights provided for in Clause 7 and the consequences set forth therein, in particular claims based on defects, claims under section 280 BGB which, according to former case law for breach of a representation or warranty, would have been considered as claims based on breach of pre-contractual obligations (culpa in contrahendo) or positive breach of contractual obligations, rights of rescission because of an absence of essential qualities, or any claims under section 313 BGB (Wegfall der Geschäftsgrundlage) are excluded. Any claims for specific performance (Vertragserfüllung) under this Agreement, or based on wilful misconduct or sections 123 and 826 BGB shall not be affected.
5.6	The Parties agree that no provision of this Agreement constitutes a contract for the benefit of a third party within the meaning of section 328 BGB or otherwise (kein Vertrag zugunsten Dritter oder mit Schutzwirkung für Dritte), irrespective of whether any payment under Clause 4 in connection with this Clause 5 is made to the Purchaser, the Company or a beta Group Company.

7.4.1 Sellers shall indemnify and hold harmless the Purchaser or, at the election of the Purchaser, the respective member of the beta Group, from and against any Taxes due and payable by any member of the beta Group for time periods

(*) Confidential Treatment Requested.

-23-

starting 1 January 2004 up to and including 30 November 2005 (such period the “Indemnification Period”) (the “Indemnifiable Tax”), however, only to the extent that (i) the aggregate amount of the Indemnifiable Tax exceeds the aggregate amount of all accruals, provisions or liabilities for Taxes shown in the financial statements of the members of the beta Group as of 30 November 2005 (deferred tax assets and liabilities are disregarded in this respect), and (ii) the relevant Taxes have not already been paid to the competent Tax Authority by the Sellers or any member of the beta Group. For the sake of clarification, withholding taxes relate to the time periods in which they are triggered.

7.4.2 The Tax indemnity pursuant to 7.4.1 is granted by Sellers subject to the following:

7.4.2.1

Sellers shall not be liable for Taxes pursuant to this Clause 7.4 if and to the extent such Taxes (i) result from any change in the accounting and taxation principles or practices, the exercise of any tax or accounting election right, or the amendment of any Tax return of the Company or any member of the beta Group (including methods of submitting Tax Returns) introduced after the Closing Date, unless such changes are required by mandatory law, (ii) arise due to any transaction, merger, restructuring or other measure (e.g., a premature cancellation of a fiscal unity (Organschaft) introduced after the Closing Date), or (iii) are subject of a valid and enforceable claim for repayment or indemnification, unless (a) such claim has not been realised, and (b) cannot be realised with reasonable efforts within eighteen (18) months after the respective claim for indemnification pursuant to Clause 7.4.1 became due and payable, in which case the Purchaser or the respective member of the beta Group shall assign to Sellers such claim including all ancillary rights and documentation concurrently (Zug um Zug) with the indemnification payment by Sellers.

7.4.2.2

If and to the extent that a circumstance which triggers Taxes for which an indemnification claim under this Clause 7.4 exists in principle (dem Grunde nach) results in a reduction of the tax base of any member of the beta Group, the Purchaser or any affiliate of the Purchaser (e.g., because of the lengthening of depreciation periods or higher depreciation allowances — Phasenverschiebungen) in the Indemnification Period or in periods commencing thereafter (such reduction the “Reversal Effect”), the Sellers’ obligation pursuant to this Clause 7.4 shall be reduced by

(*) Confidential Treatment Requested.

-24-

the Tax benefit resulting from the Reversal Effect (the “Tax Benefit”). The Tax Benefit resulting from the Reversal Effect shall be calculated by applying a flat tax rate of 25 % on the aggregate amount by which the tax base is reduced because of the Reversal Effect.

7.4.3 If and to the extent that any member of the beta Group, the Purchaser or any affiliate of the Purchaser receives a Tax Refund not reflected in the financial statements of the relevant member of the beta Group as of 30 November 2005 (deferred tax assets and liabilities are disregarded in this respect), the amount of such Tax Refund shall be paid by the Purchaser to the Sellers within ten (10) days following its receipt. A Tax Refund shall be deemed received at the time it is received in cash or as a cash equivalent (including by way of set-off against any Tax liability).

7.4.4 All payments made pursuant to this Clause 7.4 shall constitute a reduction or an increase of the Purchase Price, as the case may be. If and to the extent payments are made by Sellers to a beta Group Company, such payment shall be construed as contributions (Einlagen) made by Purchaser into the respective company and shall be treated as a reduction of the Purchase Price as between the Parties to the extent permitted by applicable Tax law.

7.4.5 After the Closing Date, the Purchaser shall prepare and make, and cause the members of the beta Group to prepare and make, when due all Tax Returns required to be filed by or on behalf of the any member of the beta Group relating in whole or in part to the Indemnification Period subject to the review and prior written consent of the Sellers’ Representative, which shall not be unreasonably withheld. The Purchaser shall ensure that any Tax Return will be furnished to the Sellers’ Representative no later than thirty (30) days prior to the due date of its filing. The Sellers’ Representative shall provide the Purchaser with his comments without undue delay. The Sellers shall be deemed to have given their consent to any Tax Return timely furnished to the Sellers’ Representative for his review if he had failed to review such Tax filing and to provide his comments to the Purchaser or the respective member of the beta Group within three (3) weeks following the receipt (Zugang) thereof.

7.4.6 Payment of Indemnification

7.4.6.1 Any payment pursuant to Clause 7.4.1 shall become due and payable five (5) Business Days prior to the due date of the relevant Tax, provided that the Purchaser has provided without undue delay and at the

(*) Confidential Treatment Requested.

-25-

latest fifteen (15) Business Days prior to the due date of the relevant Tax the Sellers’ Representative with all documentation (including copies of Tax assessments) necessary to reasonably assess the claim.

7.4.6.2 In the case of any Tax being appealed and to the extent that the Tax Authority has granted a payment relief until such Tax becomes final and binding (bestandskräftig), payment of such Tax to the Tax Authority will be considered due no earlier than on the date a final and binding determination to such effect is made by either the Tax Authority or a court of proper jurisdiction. If this is not the case, the Sellers shall make a respective advance indemnification payment to the Purchaser or, at the request of the Purchaser, to the respective member of the beta Group. If the amount of the respective Tax finally assessed and to be paid is lower than the advance indemnification payment by the Sellers, then the difference shall be reimbursed by the Purchaser, including all interest earned thereon, if any, within ten (10) days after the refund has been received in cash or as a cash equivalent (including by way of set-off against any Tax liability) by the respective member of the beta Group, the Purchaser or any affiliate of the Purchaser.

7.4.7 Indemnification Procedures

7.4.7.1

Following the Closing Date, the Purchaser shall notify and shall cause the relevant member of the beta Group to notify the Sellers’ Representative of any Tax audit or assessment, dispute or administrative or judicial proceeding that is announced or commenced and that might constitute a basis for any liability under this Agreement. Such notice shall be given within eleven (11) Business Days after the Purchaser or the relevant member of the beta Group has received the relevant information from the Tax authorities. If the Purchaser or the relevant member of the beta Group has reason to believe that a payment is to be made by the Sellers pursuant to this Clause 7.4, the Purchaser shall duly give written notice to the Sellers’ Representative including those information reasonably necessary to determine the fact, amount and payment.

7.4.7.2

The Purchaser shall cause the relevant member of the beta Group (i) to give the Sellers’ Representative (at the expense of the Sellers) the opportunity to participate in any audits, disputes or administrative or judicial proceedings relating to any Tax attributable to the Indemnification

7.4.7.3 If the Purchaser has failed to comply with any of his obligations set forth in this Clause 7.4, the Sellers shall no longer be liable under this Agreement for the relevant Tax if and to the extent the relevant Tax were not payable had the Purchaser complied with its obligations. The burden of proof whether Purchaser’s failure caused such effects shall be governed by applicable law (including any rules facilitating any such proof — Beweiserleichterungen), except that such burden of proof shall be on the Purchaser with respect to the relevant Tax, if and to the extent that (i) a Tax assessment becomes binding and non-appealable and the Purchaser or the respective member of the beta Group has failed to provide the Sellers the opportunity to challenge or litigate, or to request the Purchaser or the relevant member of the beta Group to challenge or litigate, such Tax assessment in accordance with Clause 7.4.7.2, (ii) the Tax matter has been acknowledged or settled (irrespective of whether in a Tax contest or by other means including so-called package deals) without the Sellers’ Representative prior written consent, (iii) the Purchaser has failed to comply with a reasonable (taking into account the legitimate interest of the Sellers) and executable written instruction of the Sellers’ Representative regarding the relevant Tax audit, assessment or proceeding, (iv) the Purchaser has failed, despite a prior reasonable written request by the Sellers’ Representative, to grant the Sellers’ Representative access to specifically named documents, directors or employees materially relevant in connection with the defence against the Tax audit, assessment or proceeding, (v) the Purchaser has failed to notify the Sellers’ Representative about (a) a final meeting in a tax audit (Schlussbesprechung within the meaning of Sec. 201 of the German General Tax Code — Abgabenordnung) dealing with Taxes which may have to be indemnified by Sellers under this

Clause 7.4, or (b) any other meeting with representatives of the Tax authorities announced by the Tax authorities in writing with a notice period of at least three (3) Business Days and dealing with Taxes which may have to be indemnified by Sellers under this Clause 7.4, in both cases (a) and (b) at least five (5) Business Days or to the extent possible prior to the date on which such meeting takes place, or (vi) the Purchaser has submitted a letter or similar document to the Tax auditor specifically prepared for the tax audit upon written request by the Tax auditor containing statements relating to Taxes which may have to be indemnified for under this Clause 7.4 to the Tax authorities either without having informed the Sellers or in violation of a specific reasonable written instruction by the Sellers’ Representative with respect to such documents. For the purpose of (iii) and (iv) of the preceding sentence, any request or instruction made in any meeting or conference and laid down in any written minutes thereof accepted in writing by the relevant Parties and their representatives shall be deemed to be in writing.

7.4.8	Claims pursuant to Clause 7.4 shall be time barred and lapse six (6) months after (i) the relevant Tax assessment notice has becomes final and binding (bestandskraeftig und unanfechtbar), or (ii) the regular statutory limitation period for the relevant Tax.

7.4.10	The liability of Sellers with respect to Taxes shall exclusively be governed by this Section 7.4 unless explicitly stated otherwise in this Agreement or the Schedules and Annexes thereto.

7.5 Each Active Manager undertakes to use all reasonable efforts that the Company will from the date hereof until the Closing Date deliver to Purchaser management accounts in the form and to the point in time as prepared consistent with past practice on a regular basis and the Sellers in their capacity as shareholders of the Company hereby authorize the Active Managers to do so.

	Stock Corporation Act shall, for a period of three (3) years from the Closing Date, in the area of manufacturing, marketing, buying and selling of marketing authorizations and dossiers regarding generic pharmaceuticals in Germany as well as distributing generic pharmaceuticals as currently done so by beta Group, not engage in any activity which would, directly or indirectly, compete with or result in competion with such present business operations in Germany. The Relevant Sellers shall not establish or acquire, or acquire shares in, any business operations competing with the beta Group; it is understood, however, that the Relevant Sellers shall be entitled to acquire up to 10 % of the share capital of a corporation listed on a stock exchange, provided that the Relevant Sellers are excluded from any control over the management of such listed corporation competing with the beta Group. The Relevant Sellers covenant that the other companies belonging to the Relevant Sellers’ group in the aforementioned period comply with the forgoing provisions of this Section 7.6 accordingly.
	Purchaser will procure that the non-compete provisions (including respective compensations) under the current service agreements with the Active Managers will continue to apply after Closing upon request of the relevant Active Manager.
8.	RESCISSION
