PREAMBLE 
  

	(A)	W.E.T. Automotive Systems AG (the “Company”) is a German stock corporation with registered place of business in Odelzhausen, registered in the
commercial register of the local court of Munich under number HRB 119793 with a stated capital (Grundkapital) of EUR 9,600,000.00. The Company’s stated capital is divided into 3,200,000 bearer shares (the
“Shares”) without par value (auf den Inhaber lautende Stückaktien) with the International Securities Identification Number (ISIN) DE0005081608, each representing a calculatory share in the Company’s stated
capital of EUR 3.00. The bearer shares are embodied in one or more global share certificates, held in collective custody (Girosammelverwahrung) with Clearstream Banking AG, Frankfurt am Main (“CBA”) as central depository
bank for securities (Wertpapiersammelbank). 

	(B)	Out of all Shares, the Company holds 159,988 Shares in itself (which so long as they are held by the Company do not carry voting rights)
equalling 5.00% of its registered share capital and the Sellers hold in aggregate 2,297,663 Shares (the “Sellers’ Shares”) equalling 71.80% of the Company’s
registered share capital and 75.58% of the voting rights in the Company (not including the Shares held by the Company itself). The Seller’s Shares held by Seller 1 are booked on three different depository accounts, two of
which are subject to pledges in favour of third parties. Details about the number of Sellers’s Shares held by each Seller, the deposit accounts in which these are held and any encumbrances thereof are set out in more detail in the
table below:

 In relation to each Seller, each portion of Sellers’ Shares held by such
Seller in a particular deposit account according to the above table is hereafter referred to as the “Sale Shares”. 
  

	(C)	By agreement dated 6 April 2010 (the “Note Agreement”), the Company agreed to issue a loan note in the amount of up to EUR 7,163,000 and by
loan note of 16 April 2010 issued to Seller 2 a loan note in the amount of EUR 7,162,728.18 (the “Note”). As at 31 December 2010 the aggregate of principal and interest accrued on the Note (excluding the
entitlement to a final payment as set forth in the Note) amounted to approximately EUR 7,925,000. 

  

	(D)	By a senior facility agreement dated 4 August 2003, as last amended by the “Ninth Amendment Agreement to the up to EUR 284,000,000 Facility Agreement dated
4 August 2003” (the “Senior Facility Agreement”), BHF-BANK Aktiengesellschaft as agent and security agent and the lenders named therein agreed to provide to the Company and certain of its affiliates as borrowers
certain term loan and revolving loan facilities in the aggregate amount of Euro 284,000,000. According to the Senior Facility Agreement, all amounts advanced there under will become due and payable upon the occurrence of a change of control,
as would result from consummation of the transaction contemplated by this agreement. 

  

	(E)	Seller 1 and Seller 2 are subject to the terms of an intercreditor agreement dated 4 August 2003, as last amended by the “Sixth Amendment
Agreement to the Intercreditor Agreement dated 4 August 2003” on 1 April 2010 (the “Intercreditor Agreement”). According to the terms of the Intercreditor Agreement, Seller 1 and Seller 2 may not
transfer their Shares or the Notes unless the transferee (previously or simultaneously) accedes to the Intercreditor Agreement. 

  

	(F)	Purchaser wishes to acquire the Sellers’ Shares by purchasing from each Seller the Sale Shares, and/or making a voluntary tender
offer for the Shares. Sellers wish to sell or tender to Purchaser the Sellers’ Shares. Purchaser also intends (without being obliged to do so) to purchase or procure the repayment of the Note
within 18 months from acquiring the Sale Shares. 

  

	(G)	Guarantor is Purchaser’s immediate parent, holding all shares in Purchaser. In preparation of the anticipated purchase of the
Sellers’ Shares and the Note by Purchaser (the “Merger”), Sellers and Guarantor entered into a “Letter of Intent Concerning Shares in W.E.T. Automotive AG” dated
14 January 2011 and last executed by the parties thereto 19 January 2011 (the “LOI”). Guarantor has agreed to guarantee performance by Purchaser of the obligations to be assumed by Purchaser under this
agreement. 

  
 Seite 4

	(H)	Purchaser intends to secure debt financing for the Merger, on terms acceptable to Purchaser and Guarantor by executing, and having
Guarantor execute, loan facility agreements with Bank of America or any other bank selected by Purchaser (“Purchaser’s Bank”) and having Guarantor forward all or a portion of the funds it receives in
connection with its loan facility agreement to Purchaser. Further, Guarantor intends to issue new shares in Guarantor after the date hereof on terms acceptable to Guarantor and forward some or all of the funds received
through such equity issuance, to Purchaser. 

  

	(I)	Purchaser expects the Company to execute a binding loan facility agreement (“New Facility Agreement”) with Purchaser’s Bank
no later than 28 March 2011 pursuant to which the facility outstanding under the Facility Agreement is refinanced by or around the date Purchaser acquires the Sale Shares in which case the restrictions imposed on the
Note and the Shares held by Seller 1 and Seller 2 by the Facility Agreement and the Intercreditor Agreement will fall away. 

 

	(J)	In this agreement the Parties and Guarantor wish to set out the terms and conditions under which the Sellers’ Shares shall be sold to
and purchased by the Purchaser. 

 NOW THEREFORE IT IS AGREED WHAT FOLLOWS: 

 

	1.	APPROVAL 

  

	1.1	The Parties and Guarantor agree that Seller 3 shall be bound by, and benefit from, this agreement only subject to the condition that the execution
of this agreement is approved by the competent internal bodies (zuständige Gremien) of Seller 3 (“Approval”) provided that in any event, the Approval shall be deemed granted, the condition shall be deemed
satisfied and Seller 3 shall become bound by this agreement, when Seller 3 confirms that it has obtained the Approval (the “Confirmation”) to Seller 1 (who will receive such Confirmation also on
behalf of Seller 2) and to Purchaser (who will receive such Confirmation also on behalf of Guarantor) in writing (including telefax or pdf). 

 

	1.2	Seller 1, Seller 2, Purchaser and Guarantor agree that they shall be bound by this agreement irrespective of whether the Approval is
granted. The Parties’ rights to rescind this agreement pursuant to Clause 5 remains unaffected. 

  

	2.	SALE AND PURCHASE 

  

	2.1	Each Seller hereby sells to Purchaser at the Agreed Share Price (as defined below) the Sale Shares, together with all ancillary rights

that the Merger may be consummated; 

  
 Seite 6

	 	(b)	the Merger may be consummated without violating the anti-trust, cartel or similar laws under any other relevant jurisdiction (each a “Cartel Filing
Jurisdiction”) because (i) the applicable waiting period, notice period or other similar period during which the Merger cannot be consummated have expired or been terminated, or (ii) the competent merger control authorities
have cleared the Merger; 

  

	 	(c)	Purchaser has submitted to Bundesanstalt für Finanzdienstleistungsaufsicht (“BaFin”) an offer document for a public takeover (the
“Offer”) of the Company in compliance with the laws of the Federal Republic of Germany, in particular, but not limited to, the provisions of the German Securities Acquisition and Takeover Act and the respective subordinate
legislation, which contains a financing confirmation within the meaning of sec. 13 (1) sentence 2 German Securities Acquisition and Takeover Act and is not subject to any condition, rescission or other withdrawal right other than (i) the
conditions set out in Clause 4.1(a) and (b) above, (ii) the condition of Purchaser having secured the acquisition of Shares (including the Sale Shares) which represent 71.80% of the Company’s registered
share capital and (iii) as provided for by mandatory applicable laws (the “Offer Document”); 

  

	 	(d)	Purchaser presents to Seller 1 and Seller 3 original declarations (or certified copies thereof), together with any underlying documentation
reasonably requested by Seller 1, from Purchaser’s Bank confirming that the Agreed Share Price for the Sale Shares of all Sellers will after satisfaction or waiver of the Closing Conditions be advanced
to Sellers by Purchaser’s Bank at any time upon Guarantor’s or Purchaser’s request; 

  

	 	(e)	the Company has executed the New Facility Agreement; 

  

	 	(f)	Seller 1 has delivered to Purchaser duly executed written statements conforming in all material respects with the form as attached as Annex 4.1(f) from

(payable with regard to the ING Shares and, respectively, the UniCredit Shares) on the Agreed Account. 

  

	4.2	Purchaser shall immediately inform Sellers when a Closing Condition set out in Clause 4.1(a) or 4.1(b) has been fulfilled and provide Seller
1 without undue delay with an unqualified confirmation from its lawyers addressed to Sellers confirming to Sellers that the respective Closing Condition has occurred, in each case accompanied by copies of the related documentation.

the Closing Conditions set forth in Clause 4.1(e) and (f); the Closing Conditions in Clause 4.1(a) and (b) may only be waived by Seller 1 and Purchaser jointly. Unless otherwise agreed by the
Parties in writing, the effect of a waiver shall, however, be limited to eliminating the need that the respective Closing Condition be fulfilled before the Closing and shall neither prejudice the continuing obligation of the
responsible Seller, Purchaser or Guarantor, as the case may be, to fulfil such Closing Condition nor its liability for non-performance of its obligation to fulfil such Closing Condition. If Purchaser waives the
Closing Condition set out in Clause 

  
 Seite 7

 4.1(f) before 28 March 2011, it shall not be entitled to bring a claim for breach of

	 	(e)	Purchaser or Guarantor fail to take within ten Business Days from the Closing Date the Closing Actions (as defined below) to be taken

	 	(d)	Sellers fail to take within ten Business Days from the Closing Date the Closing Actions (as defined below) to be taken by them at the time
and in the manner set out in Clause 7.2, unless this is caused by Purchaser’s or Guarantor’s failure to comply with its own obligations as set out in Clause 7.2 or the Parties proceeding in accordance with Clause
8. 

  

	5.3	 If rescission is declared in accordance with Clause 5.1 or Clause 5.2, each Party and Guarantor shall deliver to the other Party

	5.6	If rescission is declared pursuant to Clauses 5.1 or 5.2, all further obligations of the Parties and of Guarantor under this agreement will terminate,

or regulation, give the other Parties and the other Parties’ legal counsel the opportunity to attend and participate in such meetings and conferences.

commitment or incur any material liability or other material obligation in order to obtain the approvals, clearances and authorizations described in this Clause 6, unless such Party consents to thereto; provided, however, that if any
Party other than Purchaser is requested to pay any material amount of cash in order to obtain any such approvals, clearances and authorizations described in this Clause 6, such other Party shall give Purchaser the
opportunity to make such payments on behalf of such other Party and (ii) require any Party to consummate the Merger if the essential terms

 of the Merger applicable to such Party have been materially modified by any
requirements or conditions imposed by a governmental entity (including, but not limited to, requiring a Party to sell, divest or otherwise dispose of any assets or business) so as to permit consummation of the transactions contemplated by
this agreement. 
  

	6.4	To the extent this is permitted by applicable law and subject to Sellers’ approval of any relevant filing or notification, Purchaser shall make any
filings and notifications required to be made with any competition authority also on behalf of Sellers. 

  

	6.5	Where Guarantor is legally required to make any cartel filing, the obligations imposed on Purchaser in this Clause 6 apply equally to Guarantor.

	 	(g)	Each Seller shall seek confirmation of receipt of the Agreed Share Price from the bank(s) with whom it keeps the Agreed Account(s) and inform
Purchaser of such confirmation promptly. 

  

	7.3	After all Closing Actions have been fulfilled (or waived), Sellers and Purchaser shall confirm in writing in a closing memorandum in such form as
shall be mutually agreed that all Closing Actions have been performed or waived and that the Closing has occurred. For the avoidance of doubt, the legal effect of such closing memorandum shall be limited to serve as evidence that all
Closing Actions have been performed or waived and that the Closing has occurred, but shall not limit or prejudice in any manner the rights of the Parties or Guarantor arising under this agreement or under applicable law.

  

	7.4	Each Seller and Purchaser hereby agree that, conditional upon (aufschiebend bedingt) the occurrence of the Closing Date, the consummation or
waiver of the actions set out in Clause 7.2(a) to (e) and receipt on the Agreed Account of the Agreed Share Price, 

  

	 	(a)	title to the Sale Shares (sold for that Agreed Share Price), including in relation thereto (i) the co-ownership rights to the underlying global share
certificates, (ii) any certificates for interest, dividends or renewal (Zins- und Gewinnanteilsscheine, Erneuerungsscheine) and (iii) any rights to subscribe for newly issued shares in the Company (Bezugsrechte), and

  

	 	(b)	such Seller’s existing membership rights relating to the Sale Shares (sold for that Agreed Share Price), and 

 

	 	(c)	such Seller’s claims for delivery (Herausgabe- und Auslieferungsansprüche) vis-à-vis BHF-BANK Aktiengesellschaft as deposit bank of the
Sale Shares (sold for that Agreed Share Price) and vis-à-vis CBA (“Delivery Claims”), and 

  

	 	(d)	in the case of Seller 1 only, any claims of Seller 1 against ING Bank N.V. under the ING Pledge for reassignment (Rückabtretung) of its
Delivery Claims in respect of the ING Shares (sold for that Agreed Share Price); 

  

	 	(e)	in the case of Seller 1 only, any claims of Seller 1 against UniCredit Bank AG under the UniCredit Pledge for reassignment
(Rückabtretung) of its Delivery Claims in respect of the UniCredit Shares (sold for that Agreed Share Price); 

 are hereby transferred to Purchaser in accordance with sections §§ 398, 413 German Civil Code (Bürgerliches Gesetzbuch). 

(Purchaser acknowledges, that to the extent the Delivery Claims assigned by Seller 1 under paragraph 7.4(c) relate to
the ING Shares or the UniCredit Shares, such Delivery Claims exist only conditional upon their reassignment in accordance with paragraphs 7.4(d) and (e).) 

 

	7.5	Sellers may waive a Closing Action for which only Purchaser or Guarantor are responsible, and vice versa. Unless otherwise agreed by the
Parties in writing, the effect of a waiver shall, however, be limited to eliminating the need that the respective Closing Action be performed by or at the Closing and shall neither prejudice the continuing obligation of the
responsible Seller, Purchaser or Guarantor, as the case may be, to bring about such Closing Action nor its liability for non-performance of its obligation to bring about such Closing Action.

  

	7.6	Should the transfer of the Sellers’ Shares require any further act or declaration, the parties shall upon Purchaser’s request take all
reasonable endeavors to take such further action and make such further declaration as and when required.

	8.	ACCEPTANCE OF TENDER OFFER 

  

	8.1	Provided (i) all Closing Conditions have been satisfied or waived or (ii) all Closing Conditions other than Closing Conditions 4.1(a) and
4.1(b) have been satisfied or waived and the Offer remains only subject to satisfaction of Closing Conditions 4.1(a) and 4.1(b) by 28 May 2011, Purchaser may request that consummation of the Closing in accordance
with Clause 7 be replaced by Sellers accepting the Offer and transferring their Sale Shares to Purchaser in accordance with the Offer Document, provided that 

 

	 	(a)	by Sellers tendering their Sale Shares in acceptance of the Offer, the Offer becomes finally binding, without there remaining any further
condition, rescission right or other risk of the Offer not being consummated, other than satisfaction or waiver by 28 May 2011 of Closing Conditions 4.1(a) and 4.1(b) or as provided for by mandatory applicable laws, and

  

	 	(b)	the Offer Document will foresee that the offer price (which shall be no less than EUR 40 per Share) (“Offer Price”) is to be paid,
upon fulfilment by no later than 28 May 2011 of its closing conditions (such conditions not to go beyond those stated in Clause 4.1(c) (i) and (ii)), to the shareholders tendering their Shares no later than 5 Business Days
following the expiration of the additional offer period pursuant to Section 16 para. 2 German Securities Acquisition and Takeover Act or, in case later, the satisfaction or waiver of Closing Conditions 4.1(a) and 4.1(b) by
28 May 2011. 

  

	8.2	If Sellers and Purchaser proceed in accordance with Clause 8.1 (and irrespective of whether the conditions stated in the Offer will eventually be
satisfied), their rights and obligations under Clauses 2, 3, 5 and 7 (except for Clause 7.2(e)) shall be replaced by the corresponding terms of the Offer and (ii) Sellers undertake not to exercise any withdrawal or rescission
right they may have with respect to their tendered Shares pursuant to Section 22 para. 3 German Securities Acquisition and Takeover Act. 

  

	9.	SELLERS’ GUARANTEES 

  

	9.1	Each Seller hereby severally represents and warrants, in each case only in respect of itself and the Sale Shares sold by it, to Purchaser (but not
to Guarantor) in the form of an independent guarantee (Selbständiges Garantieversprechen) within the meaning of Secs. 311 (1), 241 of the German Civil Code as of the Signing Date and as of the Closing Date the
following: 

  

	 	(a)	The execution and performance by Seller of this agreement is within its corporate powers and has been duly authorized by all necessary corporate actions on its
part. Except for possible merger control clearance, Seller does not require any consent or governmental authorization in connection with the execution and consummation of this agreement. 

 

	 	(b)	Seller is the sole and unrestricted owner of the Sale Shares, which are free and clear of any liens, encumbrances, pledges or other in rem rights
of third parties, except for the ING Pledge and the UniCredit Pledge which will only be released upon receipt of the Agreed Share Price for the ING Shares and, respectively, the UniCredit Shares on the Agreed
Account and except for pledges under general terms and conditions with the Sellers’ deposit account bank. No dividends have been paid or resolved to be paid with respect to the Sale Shares since 1 January 2010.

  

	9.2	None of the Sellers represents, warrants, guarantees or otherwise accepts any liability for the legal, economic or financial position of the Company nor
shall any of the Sellers be responsible or liable for or otherwise be affected for the purposes of this agreement by the future development of the Company (including its subsidiaries) after the date hereof. 

  
 Seite 12

	10.	REMEDIES 

  

	10.1	Subject to Clauses 11 and 12 below, in case a guarantee given by a Seller in Clause 9 (“Guarantee”) is incorrect, the respective Seller
or Sellers shall bring about the guaranteed position, provided that only in case this cannot be effected otherwise within a reasonable period of time of no less than two months or is impossible or the respective Seller(s) finally
refuse(s) (verweigert ernsthaft und endgültig) to do so, respective Seller or Sellers shall, subject to Clause 10.2, pay to Purchaser the amount of money necessary to put Purchaser in the financial position in
which it would have been if the Guarantee had been correct. 

  

	10.2	If, in case of a violation of the title Guarantee in Clause 9.1(b), a Seller would, but for this Clause 10.2, be obliged to pay damages in an amount
exceeding 10% of the Agreed Share Price, then such Seller shall instead of paying such damages have the right to repay to Purchaser the Agreed Share Price concurrently (Zug um Zug) against re-transfer of the
Sale Shares to it (or any other person it may designate). (For the avoidance of doubt, the Agreed Share Price and the corresponding 10% threshold shall be determined separately in relation to each of the ING Shares, the
UniCredit Shares and the Indigo Shares.) 

  

	11.	STATUTE OF LIMITATION 

All claims against any Seller under this agreement shall become time-barred 12 months after the Closing Date, provided
however that the limitation period in case of a violation of the Guarantees in Clause 9.1(b) shall be 24 months from the Signing Date. 
  

	12.	LIMITATION OF LIABILITY 

  

	12.1	Each Seller shall only be responsible for its own obligations. No Seller shall be liable or responsible to Purchaser for (i) any breach of any
Guarantee or any other liability or obligation of any other Seller or (ii) any claim against another Seller. If more than one Seller is liable in relation to the same set of facts and circumstances, there
(i) shall be only one claim arising from these facts and circumstances and (ii) these Sellers shall be liable as several debtors (Teilschuldner) therefor; the individual liability of each Seller for such claim shall
correspond to the percentage rate reflecting the relation of the calculatory share (anteiliger Betrag des Grundkapitals) of each such Seller’s Sale Shares to the aggregate calculatory share of the Sale Shares of all
Sellers liable for such claim, but in no case be higher than the respective Seller’s maximum liability under Clause 12.4. In no case shall any liability of Sellers for any claim, breach or obligation be a joint and several
liability or responsibility of Sellers (Gesamtschuldnerschaft). 

  

	12.2	Sellers shall under no circumstances be liable 

  

	 	(a)	for internal administrative and other overhead costs of Purchaser, Guarantor or the Company, consequential damages, loss or reduction of revenues
or profits, damage to good will or damages based on an alleged inappropriateness of the Agreed Share Price; 

  

	 	(b)	if Sellers’ participation rights under Clause 14 have not been observed, unless and except to the extent Purchaser’s failure or delay in doing
so, has not increased the affected Seller’s liability; 

  

	 	(c)	or if after the Closing Date a liability is created or increased as a result of any action or absence of mitigation efforts of Purchaser, Guarantor
or the Company. 

  

	12.3	Purchaser may only assert claims against any Seller, if and to the extent that the aggregate amount of all such claims exceeds EUR 250,000, it being
understood that if this threshold is exceeded, only the exceeding amount may be claimed. 

  
 Seite 13

	12.4	Each Seller’s liability under this agreement shall be limited to 10% of the Agreed Share Price. This limitation shall not apply in case of a
violation of the Guarantee in Clause 9.1(b), in which case each Seller’s liability shall be limited to the amount of the Agreed Share Price paid for the Sale Shares affected. (For the avoidance of doubt, the
Agreed Share Price and the corresponding 10% threshold shall be determined separately in relation to each of the ING Shares, the UniCredit Shares and the Indigo Shares.) 

 

	12.5	The Parties and Guarantor agree that the limitations stipulated in Clauses 11 and 12 of this agreement shall survive a rescission or other termination of
this agreement and shall apply to any and all rights and remedies which Purchaser or Guarantor may have against one or more Seller(s) for any breach of any Guarantee or other (contractual or non-contractual) obligation
under or in connection with this agreement, the LOI or in any way whatsoever otherwise arising in connection with the Merger and its preparation. Except for claims for specific performance of express obligations under this agreement
(primäre Erfüllungspflichten) and damages claims for violating such claims for specific performance, all rights, claims and remedies of any legal nature that any Party or Guarantor may otherwise have against each other
shall be excluded. This shall in particular apply to any right to rescind (zurücktreten) (other than pursuant to Clause 5) from, or otherwise terminate, this agreement or to require the winding up of the Merger, any claims
for breach of pre-contractual obligations (culpa in contrahendo) including claims under Sections 241 para. 2, 311 para. 2 and para. 3 German Civil Code, any claims for breach of contract (Schadensersatz wegen Pflichtverletzung)
including claims under Sections 280, 282 German Civil Code (unless stipulated otherwise in the foregoing sentence), any claims based on frustration of contract (Störung der Geschäftsgrundlage) including claims under Section 313
German Civil Code, any claims for defects of the Sale Shares or the business of the Company (including its subsidiaries) under Sections 437 to 441 German Civil Code, and any claims under tort including claims under Sections 823 et seq.
BGB, provided that Clauses 12.3 and 12.4 shall not apply to claims for willful deceit (arglistige Täuschung) or other intentional breaches of contract (vorsätzliche Vertragsverletzungen). 

 

	13.	GUARANTEES BY PURCHASER 

  

	13.1	Purchaser and Guarantor represent and warrant to Sellers in the form of a Guarantee (Selbständiges Garantieversprechen) within
the meaning of Secs. 311 (1), 241 of the German Civil Code as of the Signing Date and as of the Closing Date the following: 

  

	 	(a)	The execution and performance by each of them of this agreement is within their corporate powers and has been duly authorized by all necessary corporate actions on the
part of Purchaser and Guarantor. Except as stated in Clause 6, Purchaser and Guarantor do not require any consent or governmental authorization in connection with the execution and consummation of this agreement.

  

	 	(b)	Purchaser and Guarantor are not aware of any material inaccuracies or omissions in information regarding the Company which either of them has
received from either Seller or the Company itself. 

  

	13.2	In case of a violation of the guarantees contained in Clause 13.1, Clauses 10, 11, 12.2 to 12.5 and 14 shall apply mutatis mutandis. 

 

	13.3	Except to the extent required by mandatory law, Purchaser shall not, and shall cause the Company (including its subsidiaries) not to, raise any claims
relating to actions taken prior to Closing against any Seller in its capacity as direct or indirect shareholder of the Company. 

  
 Seite 14

	14.	PARTICIPATION, INFORMATION, MITIGATION 

  

	14.1	Purchaser shall promptly 

  

	 	(a)	inform Seller 1 and, if different, the affected Seller, by courier or registered letter with return receipt (Einschreiben mit Rückschein) of
any circumstance whereby it reasonably appears that any Seller is or may be liable to make any payment under this agreement, stating, to the extent possible, the grounds and nature of the potential claim and its estimated amount, within a
period of one month from the time Purchaser or Guarantor learns of such circumstance; provided, however, that Purchaser’s failure to give, or delay in giving, such to Seller 1 and, if different, the affected
Seller, will relieve the affected Seller of any liability or obligation under this agreement, unless and except to the extent, and only to the extent, such affected Seller is not prejudiced as a result of such failure or delay
and Purchaser can show the amount by which Seller was not so prejudiced; and 

  

	 	(b)	thereafter keep Seller 1 and, if different, the affected Seller reasonably informed of all developments in relation thereto; and 

 

	 	(c)	provide all such information and documentation (no matter how it is recorded or stored) as Seller 1 or, if different, the affected Seller shall reasonably
request in connection therewith; and 

  

	 	(d)	ensure that the affected Seller (through or together with its advisers who have to be subject to market standard confidentiality agreements or a professional
duty of secrecy) can investigate the basis of and the amount potentially payable with respect to a potential liability claim, provided that the right to investigate includes the right to receive all information and assistance, have access to
premises and personnel during ordinary working hours and the right to examine and copy or photograph any assets, accounts, documents or records, in each case to the extent actually or potentially relating to the claim, as the affected Seller
may reasonably request; and 

  

	 	(e)	take, and shall cause the Company to take, all reasonable steps and action as are necessary or as the affected Seller may require in order to mitigate any
claim against any Seller and act and cause the Company to act, in accordance with such request, subject to Purchaser and the Company being indemnified by the affected Seller against all reasonable costs and
expenses incurred in connection therewith. 

  

	14.2	In circumstances where (i) a claim is made against Purchaser or Company which should reasonably be expected to give rise to a claim against a
Seller or (ii) Purchaser or the Company should reasonably be expected to be able to recover from a third party any sum in respect of any facts or circumstances by reference to which Purchaser has or should be
reasonably expected to have a claim against a Seller, Purchaser shall and shall procure that the Company, in each case prior to taking any action under this agreement, promptly and diligently take all such action as the affected
Seller may reasonably request, including the institution of proceedings and the instruction of professional advisers approved by the affected Seller to act on behalf of Purchaser or the Company to avoid, dispute, resist,
compromise, defend or appeal against any claim pursuant to (i) or make such recovery pursuant to (ii), as the case may be, in accordance with the instructions of the affected Seller to the intent that such action shall be delegated
entirely to affected Seller. 

  

	14.3	In circumstances where a Party has paid to the other Party an amount in respect of a claim under this agreement and subsequent to the making of such
payment the receiving Party recovers from some other person a sum which is referable to that payment, the receiving Party shall promptly repay to the paying Party an amount equal to the amount so recovered (net of costs of
recovery) or, if lower, the amount paid by that paying Party to receiving Party. 

  
 Seite 15

	14.4	If and to the extent a claim with respect to a breach of a Guarantee exists, all reasonable costs and expenses incurred by Purchaser and all costs
incurred for meeting any requests of an affected Seller shall be borne by that Seller liable for such breach; if and to the extent a claim with respect to a breach of a Guarantee does not exist, all reasonable costs and expenses
incurred by any Seller shall be borne by Purchaser. 

  

	15.	PARENT GUARANTEE 

  

	15.1	Guarantor hereby irrevocably and unconditionally guarantees to each Seller the due and punctual performance and satisfaction by Purchaser of all
obligations and liabilities Purchaser incurs under, as a result of or otherwise in connection with this agreement. 

  

	15.2	If any obligation of Purchaser under this agreement is not satisfied when due, Guarantor shall upon first written demand of the affected Seller by
courier or registered letter with return receipt and in any event within three Business Days of receipt by Guarantor of such request from any affected Seller pay to that Seller whatever amount owed by Purchaser to
that Seller pursuant to this agreement. 

  

	15.3	This guarantee is a continuing guarantee and will extend to the ultimate balance of all sums payable by Purchaser under this agreement, regardless of any
intermediate payment or discharge in whole or in part. 

  

	15.4	If any discharge or arrangement is made in whole or in part on the faith of any payment, security or other disposition which is avoided or must be restored on
insolvency, liquidation or otherwise without limitation, the liability of Guarantor under this Clause 15 will continue as if the discharge or arrangement had not occurred. 

 

	15.5	Guarantor and Purchaser hereby waive any right they may have of first requiring a Seller to proceed against or enforce any other right or security
or claim payment from any person, including, without limitation, Purchaser, before claiming from Guarantor under this agreement. 

  

	15.6	Guarantor acknowledges that except for Clauses 18 and 20 of this agreement, this agreement does not create any rights of or for the benefit of Guarantor
and that Guarantor shall not be entitled to claim performance of or assert any other rights under or arising out of this agreement. 

  

	16.	ACKNOWLEDGEMENT OF CHANGE OF CONTROL 

 Purchaser acknowledges that the Merger will constitute a change of control under the Senior Facility Agreement which, among other things, will entitle the financing bank(s) to declare
all or part of the outstanding amounts under such debt arrangement immediately due and payable. Purchaser further acknowledges that Sellers and/or the Company have notified or will notify the financing banks of the Merger
contemplated by this agreement. Sellers have agreed to support Purchaser and the Company in any refinancing efforts, provided that no Seller shall be under any obligation or incur any liability risk or liability in
relation to such agreement to support.

	17.1	The Parties and Guarantor mutually undertake to keep Confidential Information (as defined below) secret and confidential vis-à-vis any third

21680 Haggerty Road, Suite 101 Northville, Michigan 48167, USA 
 (hereinafter “Amerigon”), 
 and 

Amerigon Europe GmbH, 
 Ulmer Strasse 160b, 81656 Augsburg, Germany 
 (hereinafter “Amerigon
Europe” or the “Bidder”, as the case may be, 
 and with W.E.T. and Amerigon each of them a
“Party” and collectively the “Parties”). 
 Preamble 

 

	1.	W.E.T. is a German stock corporation (Aktiengesellschaft) with its seat in Odelzhausen, Germany, registered with the commercial register at the local court of
Munich under HRB 119793. The Company is one of the leading suppliers of seat climate technology, automobile seat heaters and automotive cable technology. 

 

	2.	The nominal share capital of the Company amounts to EUR 9,600,000.00 and is divided into 3,200,000 bearer shares without par value (the “Shares”).
The Shares are admitted for trading at the regulated market at the Frankfurt Stock Exchange (General Standard) and are traded under ISIN DE0005081608. In addition, the Shares are traded at the stock exchanges of Berlin, Stuttgart, Dusseldorf,
Hamburg and Munich. 

  

	3.	Indigo Capital IV L.P., London (“Indigo Capital”), is the owner of 926,497 Shares (the “IC-Shares”), ICWET L.P., London
(“ICWET”), is the owner of 1,075,866 Shares (the “ICWET-Shares”), and Industrie-Beteiligungs-Gesellschaft mbH, Frankfurt (“IBG”, together with Indigo Capital and ICWET the

	4.	Amerigon is a corporation incorporated under the laws of Michigan, USA. Amerigon is a leader in developing products based on advanced thermoelectric technologies for a
wide range of global markets and applications. The common stock of Amerigon is quoted at NASDAQ under “ARGN”. 

  

	5.	Amerigon Europe is a German limited liability company (Gesellschaft mit beschränkter Haftung) with its seat in Augsburg, registered with the commercial
register at the local court of Augsburg under HRB 25596. All shares in Amerigon Europe are held by Amerigon. 

  

	6.	The Parties wish to combine their businesses and to settle a US-patent litigation which is currently pending between them. In order to do so, Amerigon is interested in
acquiring through the Bidder, and the Bidder is interested in acquiring itself, the Sale Shares from the Sellers. The Sellers are interested in selling the Sale Shares to the Bidder. Therefore, Amerigon and the Sellers have signed, on
14 January 2011, a Letter of Intent in which Amerigon has confirmed its intention to enter into a binding agreement for the acquisition of the Sale Shares from the Sellers at a price of EUR 40.00 per Share (the “Letter of
Intent”). 

  

	7.	Amerigon intends, after entering into an agreement with the Sellers, to have the Bidder acquire the Sale Shares and to have the Bidder make a voluntary public offer for
all Shares other than the Sale Shares which the Company has issued (the “Remaining Shares” and the “Tender Offer”, respectively, and the acquisition of the Sale Shares by the Bidder and the Tender Offer collectively
the “Transaction”). Therefore, equally on 14 January 2011, Amerigon and the Company have signed a Letter of Interest in which Amerigon has expressed its interest to carry out the Transaction and to make a voluntary tender
offer for the Remaining Shares at a price of at least EUR 40.00 per Share (the “Letter of Interest” and the price per Remaining Share of at least EUR 40.00 the “Minimum Offer Price”). The intentions of
Amerigon and the Bidder with regard to the future business activity of the Company in the sense of Sec. 11 para. 2 sentence 3 no. 2 of the German Securities Acquisition and Takeover Act (Wertpapiererwerbs- und
Übernahmegesetz, WpÜG) are set out in Sec. IV. of this agreement (the “BCA” or the “Agreement”). 

  

	8.	According to both, the Letter of Intent and the Letter of Interest, Amerigon has received letters from financing sources indicating a high likelihood of raising the
equity funds and securing the debt financing necessary to complete the Transaction. 

  

	9.	Prior to the signing of this Agreement, Amerigon and its advisors have carried out a limited due diligence with regard to the Company in the course of which they have
assessed the financial, commercial, legal, factual and other circumstances of the Company and its business (the “Due Diligence”). As a result of the Due Diligence, Amerigon has made its own evaluation of the Transaction and has
resolved to carry out the Transaction on the terms set forth in this Agreement. 

  

			
	 Business Combination Agreement - W.E.T. AG / Amerigon, Inc. / Amerigon Europe
GmbH
	  	Page 3 of 16

 

	10.	Prior to the signing of this Agreement, the management board of the Company (the “W.E.T. Management Board”) has, to the extent possible and based on
the information available to it, extensively and comprehensively evaluated the Transaction and its foreseeable consequences to both, the Company and its shareholders. As of the signing of this Agreement, the W.E.T. Management Board is of the opinion
that the Transaction is in the best interest of the Company and its shareholders. In particular, after taking into consideration the intentions of Amerigon and the Bidder with regard to the future business activity of the Company as set out in this
Agreement, the W.E.T. Management Board is of the opinion that, as of the signing of this Agreement, the Minimum Offer Price is fair and appropriate. 

  

	11.	In order to independently verify its assessment regarding the financial fairness and appropriateness of the Minimum Offer Price, the W.E.T. Management Board intends to
have a fairness opinion submitted by an independent financial institution or audit firm (the “Fairness Opinion”) prior to issuing its reasoned opinion according to Sec. 27 of the German Securities Acquisition and Takeover Act.

  

	12.	Based on the aforementioned, in particular taking into account their independent assessment and evaluation of the Transaction, the Parties wish to proceed with and
accomplish the Transaction. Accordingly, by entering into this Agreement, the Parties intend to establish the basic elements of the Transaction, in particular, but not limited to, (i) the structure of the Transaction and the terms and
conditions of the Tender Offer (Sec. I.), (ii) the promotion and assistance of the Transaction by the W.E.T. Management Board to the extent legally permissible (Sec. II.), (iii) the future corporate structure of
Amerigon and the Company, including, but not limited to, the organization and composition of their legal representative bodies (Sec. III.), (iv) the intentions of Amerigon and the Bidder with regard to the future business activity
of the Company (Sec. IV.), and (v) the necessary filings in connection with the Transaction, in particular filings with the competent anti-trust authorities (Sec. V.). 

NOW, THEREFORE, the Parties hereby agree as follows: 
 I. 
 Structure of the Transaction, 

Terms and Conditions of the Tender Offer 
  

	1.	The Transaction shall be effected by (i) the sale and transfer of the Sale Shares from the Sellers to the Bidder as set forth in para. 2 below, and
(ii) - subject to para. 10. below - the Tender Offer which will be made by the Bidder in the form of a voluntary takeover bid (freiwilliges Übernahmeangebot) according to Secs. 29 et seq. of the
German Securities Acquisition and Takeover Act. 

  

	2.	 The sale and transfer of the Sale Shares from the Sellers to the Bidder will be effected in accordance with the terms and conditions of a share
purchase agreement entered into, 

  

			
	 Business Combination Agreement - W.E.T. AG / Amerigon, Inc. / Amerigon Europe
GmbH
	  	Page 4 of 16

 

	 	 
at the latest on the Target Date (as defined below), between (i) the Bidder, (ii) Amerigon, and (iii) the Sellers (the “SPA”). The SPA will
provide that the Bidder may request, after the publication of the Offer Document (as defined below), from the Sellers, at its sole discretion, that the Sale Shares shall be tendered into the Tender Offer instead of being transferred to the Bidder
under the SPA, in which case the term “Remaining Shares” shall then include the Sale Shares, and the term “Remaining Shareholders” shall include the Sellers. A draft version of the SPA is attached to this Agreement
as Annex I.2. 

  

	3.	The Bidder will prepare an offer document for the Tender Offer in accordance with the laws of the Federal Republic of Germany, in particular, but not limited to, the
provisions of the German Securities Acquisition and Takeover Act and the respective subordinate legislation (the “Offer Document”). The Offer Document will reflect the terms and conditions for the Tender Offer as set forth in this
Agreement, mainly, but without limitation to, the structure of the Transaction, the Minimum Offer Price, the Tender Offer Conditions (as defined below), the future corporate structure of W.E.T. and Amerigon, the intentions of Amerigon and the Bidder
with regard to the future business activity of the Company, the financing of the Transaction as well as the tender offer procedure and the timing of the Transaction. 

 

	4.	The Bidder will use its commercially reasonable efforts to submit the Offer Document to the German Financial Supervisory Authority (Bundesanstalt für
Finanzdienstleistungsaufsicht, BaFin, the “FSA”) within four weeks after the publication of its decision to make the Tender Offer according to Sec. 10 para. 1 of the German Securities Acquisition and Takeover Act (the
“Tender Offer Announcement”), at the latest on 28 March 2011 or, if the FSA will grant an extension of this four weeks period, at such time as indicated by the FSA in its decision on the extension request or as otherwise
accepted by the FSA as the latest possible date for submission (the “Tender Offer Submission Date”). The Parties acknowledge that if the Bidder fails - due to a lack of secured financing - to submit the Offer Document to
the FSA by the Tender Offer Submission Date this Agreement may be terminated pursuant to Sec. VI, but that neither the Bidder nor Amerigon shall have any liability whatsoever resulting from failure to submit such document by such date.

  

	5.	The Bidder will publish the Offer Document in accordance with Sec. 14 para. 3 sentence 1 of the German Securities Acquisition and Takeover Act
immediately after approval of the Offer Document by the FSA, at the latest within three bank working days (the “Offer Publication Date”) in Frankfurt a. M., Germany, after expiry of the review period (without the FSA having
prohibited the Tender Offer) according to Sec. 14 para. 2 sentence 1 of the German Securities Acquisition and Takeover Act. 

  

	6.	 According to the Offer Document, the price per Remaining Share will be the Minimum Offer Price of at least EUR 40.00. The Minimum Offer Price will
be paid to the shareholders of the Remaining Shares (the “Remaining Shareholders”) in cash. The Tender Offer will only and exclusively be subject to the conditions of (i) the Bidder acquiring Shares in the Company
(including the Sale Shares) which correspond to 71.80 per cent 

  

			
	 Business Combination Agreement - W.E.T. AG / Amerigon, Inc. / Amerigon Europe
GmbH
	  	Page 5 of 16

 

	 	 
of the total number of all issued Shares in the Company (including, for the avoidance of doubt, the Treasury Stock), and (ii) the receipt of all necessary clearances by US, European
and other regulatory authorities, including, but not limited to, cartel clearance (the “Tender Offer Conditions”). 

  

	7.	It is currently envisaged that the Offer Document will provide for an acceptance period for the Tender Offer of four weeks after the publication of the Offer Document
according to Sec. 14 para. 3 sentence 1 of the German Acquisitions and Takeover Act (Sec. 16 para. 1 of the German Securities Acquisition and Takeover Act), followed by the additional acceptance period of two weeks according to
Sec. 16 para. 2 of the German Securities Acquisition and Takeover Act (the “Additional Acceptance Period”). 

  

	8.	The consummation of the Transaction, consisting in the transfer in rem to the Bidder of (i) the Sale Shares in accordance with the terms and
conditions of the SPA (in case such Sale Shares have not been tendered into the Tender Offer), and (ii) the Remaining Shares for which the Tender Offer was accepted (the “Closing”), shall take place without undue delay
after the expiry of the Additional Acceptance Period, provided, however, that the Tender Offer Conditions have been met. 

  

	9.	Amerigon is currently taking steps to ensure that the necessary financial means for the financing of the Transaction are at the Bidder’s disposal, when the
respective obligations are due. As required by Sec. 13 para. 1 sentence 2 of the German Securities Acquisition and Takeover Act, the Bidder will provide the written confirmation of an independent investment services provider
(unabhängiges Wertpapierdienstleistungsunternehmen) to be determined, that it has taken such measures which are necessary to ensure that the necessary means to perform its obligations under the Tender Offer are at its disposal when the
consideration is due (the “Financing Confirmation”). 

  

	10.	In case Amerigon respectively the Bidder is not able to meet the timeline set forth in preceding paras. 3 through 5 above, but nevertheless acquires
“control” within the meaning of Sec. 29 para. 2 of the German Securities Acquisition and Takeover Act pursuant to the consummation of the SPA, Amerigon shall be obliged to make a mandatory tender offer in accordance with
Secs. 35 et seq. of the German Securities Acquisition and Takeover Act, but shall not assume any other liability towards the Company, W.E.T Management Board or any other third party in that respect. 

II. 

Promotion and Assistance of the Transaction 
 by the W.E.T. Management Board 
  

	1.	Based on its evaluation of the Transaction as set out in Sec. 9. of the Preamble to this Agreement, the W.E.T. Management Board, as of the signing of this
Agreement, supports the Tender Offer and the Transaction. 

  

	2.	 Subject to its duties and responsibilities according to German statutory law, mainly its

  

			
	 Business Combination Agreement - W.E.T. AG / Amerigon, Inc. / Amerigon Europe
GmbH
	  	Page 6 of 16

 

	 	 
fiduciary duties, duties of loyalty and duties of care according to Sec. 93 of the German Stock Corporation Act, as well as the needs and requirements according to the German Securities
Acquisition and Takeover Act and subordinate legislation (the “Legal Requirements”), and further subject to the conditions that, as of the publication of the W.E.T. Management Board’s reasoned opinion according to Sec. 27
of the German Securities Acquisition and Takeover Act (the “W.E.T. Management Opinion”), 

  

	 	2.1	the circumstances and assumptions based on which the W.E.T. Management Board has made its evaluation of the Transaction and its foreseeable consequences to the Company
and its shareholders as set out in Sec. 9. of the Preamble to this Agreement have not materially changed; and 

  

	 	2.2	the Tender Offer is made in accordance with this Agreement and German statutory law, and the Offer Document reflects the terms and conditions for the Tender Offer as
set forth in this Agreement; and 

  

	 	2.3	the Fairness Opinion concludes that the Minimum Offer Price offered to the Remaining Shareholders in the Offer Document is fair and appropriate as of the publication of
the W.E.T. Management Opinion; and 

  

	 	2.4	the Financing Confirmation was provided by the Bidder in accordance with Sec. 13 para. 1 sentence 2 of the German Securities Acquisition and Takeover Act
(paras. 2.1 through 2.4 above collectively the “Support Conditions”), 

 the W.E.T.
Management Board will, as part of the W.E.T. Management Opinion, confirm that in its opinion the Minimum Offer Price is fair and appropriate and that it supports the Tender Offer and the Transaction and recommends to the Remaining Shareholders to
accept the Tender Offer. 
  

	3.	The circumstances and assumptions based on which the W.E.T. Management Board has made its evaluation of the Transaction and its foreseeable consequences to the Company
and its shareholders as set out in Sec. 9. of the Preamble to this Agreement shall be deemed to have materially changed (in the sense of para. 2.1 above), inter alia, but not exclusively, in case a third party has, without hereunto
having been solicited or encouraged by the W.E.T. Management Board, publicly announced or published a competing tender offer (a “Competing Tender Offer”) which the W.E.T. Management Board, after having extensively and
comprehensively evaluated the Competing Tender Offer and its foreseeable consequences to both the Company and its shareholders, considers superior to the Tender Offer. 

 

	4.	 The terms of this Agreement and of the Letter of Interest do not restrict the rights and duties of the W.E.T. Management Board and of the Company, or
any other rights and obligations of the W.E.T. Management Board and of the Company under the Legal Requirements, to extensively and comprehensively evaluate a publicly announced or published Competing Tender Offer and its foreseeable consequences to
both the Company 

  

			
	 Business Combination Agreement - W.E.T. AG / Amerigon, Inc. / Amerigon Europe
GmbH
	  	Page 7 of 16

 

	 	 
and its shareholders, taking into account all relevant facts and circumstances, and to assess whether the Competing Tender Offer is preferable to the Tender Offer and, should this be the case, to
establish that, in the opinion of the W.E.T. Management Board, the Competing Tender Offer is superior to the Tender Offer, inter alia, but not limited to, in press releases or in the reasoned opinion to the Competing Tender Offer according to
Sec. 27 of the German Securities Acquisitions and Takeover Act. 

  

	5.	Subject to the Legal Requirements and as long as the Support Conditions are satisfied, the W.E.T. Management Board shall not revoke, or modify, the W.E.T. Management
Opinion until the expiry of the Additional Acceptance Period. 

  

	6.	Subject to the Legal Requirements and as long as the Support Conditions are satisfied, the W.E.T. Management Board shall recommend, and positively refer to, the Tender
Offer and the Transaction in any communication with its shareholders, other stakeholders of the Company and in publications, events or speeches addressed to the public such as interviews, roadshows, press conferences or the like.

  

	7.	Subject to the Legal Requirements and as long as the Support Conditions are satisfied, the W.E.T. Management Board shall not, without approval of the Bidder,
(i) exercise any authorized capital within the meaning of Sec. 202 of the German Stock Corporation Act or support the issuance of any stock options or similar instruments which entitle its owner to acquire or subscribe to shares in
the Company or (ii) dispose of any part or all of the Treasury Stock, or acquire (directly, or indirectly, by itself, its subsidiaries or a third person acting on behalf of any of it or them) any new treasury stock or conclude (directly,
or indirectly, by itself, its subsidiaries or a third person acting on behalf of any of it or them) any agreement within the meaning of Sec. 31 para. 6 of the German Securities Acquisitions and Takeover Act. 

 

	8.	Subject to the Legal Requirements, the Company shall schedule the next shareholders’ meeting of the Company to take place not earlier than 14 July 2011.

  

	9.	The Company hereby warrants to the Bidder that there are no material inaccuracies of the financial information published by the Company which are known to the W.E.T.
Management Board. 

 III. 
 Future Corporate Structure of Amerigon and W.E.T. 
  

	1.	 The Parties agree that both, the Bidder and the Company, shall remain separate corporate entities also after the Closing. The Parties acknowledge that,
according to the ruling of the FSA (Bescheid) dated 31 March 2010, the Company may not distribute dividends to its current shareholders until 30 September 2012 (the “Dividend Ban”). The Parties are of the
joint opinion that the Dividend Ban does not apply to dividends resolved upon in a shareholders’ meeting following the Closing, i.e. after the Bidder has acquired control over the Company. Amerigon and the Bidder will not vote for a
dividend payment of 

  

			
	 Business Combination Agreement - W.E.T. AG / Amerigon, Inc. / Amerigon Europe
GmbH
	  	Page 8 of 16

 

	 	 
more than EUR 2.00 per Share in any shareholders’ meeting of the Company prior to the DPLTA Effective Date (as defined below). 

 

	2.	Subject to approval of the respective corporate bodies, in particular the shareholders’ meeting of the Company, the Bidder and the Company shall enter, after the
Closing, into a domination and profit transfer agreement within the meaning of Secs. 291 et seq. of the German Stock Corporation Act (Beherrschungs- und Gewinnabführungsvertrag im Sinne der
§§ 291 ff. AktG) to be agreed upon between the Company and the Bidder in due course and good faith (the “Domination and Profit Transfer Agreement”). The Domination and Profit Transfer Agreement shall be
submitted for approval to the Company’s shareholders’ meeting, if possible, during 2011. The Domination and Profit Transfer Agreement will become effective upon its registration with the commercial register of the Company (the
“DPLTA Effective Date”). 

  

	3.	The Parties agree that the current composition of the W.E.T. Management Board shall, for the duration of their respective service agreements
(Anstellungsvertrag), remain unaffected after the Closing. Accordingly, Amerigon and the Bidder hereby undertake, notwithstanding the provisions in Sec. 3 below, (i) to refrain from any legal or factual act in order to effect
a premature termination of the appointment (Bestellung) and / or service agreement (Anstellungsvertrag) of any member of the W.E.T. Management Board, and (ii) to make best efforts, as far as legally permissible, that
representatives of Amerigon or the Bidder, who are members of a corporate body of the Company, do not take, induce or support any such legal or factual act; Sec. 84 para. 3 of the German Stock Corporation Act remains unaffected.

  

	4.	The Parties agree that it is their common understanding that the Company, represented by the supervisory board, and the current members of the W.E.T. Management Board
enter into new service agreements as of the DPLTA Effective Date. The Parties undertake to make best efforts, as far as legally permissible, that the current service agreements of the members of the W.E.T. Management Board are amended prior to the
signing of the Domination and Profit Transfer Agreement in such way that each member of the W.E.T. Management Board shall be entitled to resign from his office and terminate his service agreement with effect as of the DPLTA Effective Date in case
the Company and the respective member of the W.E.T. Management Board have not, prior to the DPLTA Effective Date, agreed upon the contents and conclusion of a new service agreement. The termination has to be declared within two weeks following the
DPLTA Effective Date. In such case of a termination of his service agreement by a member of the W.E.T. Management Board, the termination shall become effective two months following the DPLTA Effective Date and the respective member of the W.E.T.
Management Board shall be entitled to the payment of the remuneration (Gesamtvergütung) for the remaining term of his current service agreement and his appointment as member of the W.E.T. Management Board, assuming an achievement of
100 per cent (Zielerreichung von 100 %) with regard to any and all bonuses, royalties (Tantiemen) or other performance-related parts of his remuneration.

GmbH
	  	Page 9 of 16

 

	5.	In order to secure the corporate powers of the current members of the W.E.T. Management Board after the DPLTA Effective Date, the Parties agree that the current CEO of
the Company, Mr. Caspar Baumhauer, shall, at the DPLTA Effective Date, and as far as legally permissible, in particular according to German statutory law or applicable US law, become board member of Amerigon. 

IV. 

Intentions of Amerigon and the Bidder 
 with regard to the Future Business Activity of W.E.T. 
  

	1.	The Company shall persist as a stand-alone, publicly listed company in the form of a German stock corporation (Aktiengesellschaft), unless a squeeze-out
procedure is consummated pursuant to the German Stock Corporation Act or the German Securities Acquisition and Takeover Act. Accordingly, prior to the DPLTA Effective Date, neither the Bidder nor Amerigon, nor any other person affiliated with
Amerigon in the sense of Secs. 15 et seq. of the German Stock Corporation Act, nor any person qualifying as “person acting in concert” with Amerigon or the Bidder in the sense of Sec. 2 para. 5 sentence 1 of the
German Securities Acquisition and Takeover Act (gemeinsam handelnde Person) will exercise a dominating influence on the Company (beherrschenden Einfluss ausüben). Subject to the foregoing sentences, the Bidder, Amerigon, any other
person affiliated with Amerigon in the sense of Secs. 15 et seq. of the German Stock Corporation Act, and all persons qualifying as a “person acting in concert” with Amerigon or the Bidder in the aforementioned sense will
respect the autonomy of the Company in accordance with Secs. 311 et seq. of the German Stock Corporation Act, and all deliveries and services (Liefer- und Leistungsbeziehungen) between them and the Company and persons affiliated
with the Company in the sense of Secs. 15 et seq. of the German Stock Corporation Act will be rendered on customary market terms at arms’ length conditions. 

 

	2.	Amerigon entirely supports and trusts in the current business model of the Company and the W.E.T. Management Board. After the Closing, the current W.E.T. Management
Board shall continue to run the business of the Company in accordance with its legal obligations, taking into account the best interest of all stakeholders in the Company. 

 

	3.	Amerigon and the Bidder have the following intentions with regard to the future business activity of the Company (which the Bidder will describe correspondingly and in
market-customary terms in the Offer Document according to Sec. 11 para. 2 sentence 3 no. 2 of the German Securities Acquisition and Takeover Act): 

 

	 	3.1	 The seat of the Company, both the statutory and the administrative seat (Satzungssitz und Verwaltungssitz), shall remain in Odelzhausen.
Amerigon and the Bidder do not intend to make significant changes or amendments to the Company’s business branches and overall product portfolio, its subsidiaries or business sites, as well as its organizational and administrative structure
until the DPLTA Effective Date. The same applies to the overall working conditions of the employees 

  

			
	 Business Combination Agreement - W.E.T. AG / Amerigon, Inc. / Amerigon Europe
GmbH
	  	Page 10 of 16

  

 
of the Company and its subsidiaries, as well as to the existing employees’ representations. 
  

	 	3.2	Except for the conclusion of the Domination and Profit Transfer Agreement and potential measures taken thereunder, Amerigon and the Bidder do not intend to increase the
aggregate amount of financial liabilities of the Company. 

  

	4.	Amerigon assists and supports the Company’s actual and future growth strategy, and it has sufficient financial means at its disposal to support this strategy as a
stable and reliable financing partner. Accordingly, Amerigon is open, subject to a positive decision of its responsible corporate bodies in each case, to participate in future financing measures of the Company which are necessary to implement the
Company’s strategy. In particular and subject to the Company’s reasonable cooperation, Amerigon undertakes to secure the necessary bank financing of the Company in a seamless manner following the Closing. 

 

	5.	Amerigon and the Bidder hereby undertake vis-à-vis the Company for a period of twelve months after the publication of the final acceptance level of the Tender
Offer according to Sec. 23 para. 1 sentence 1 no. 3 of the German Securities Acquisition and Takeover Act upon expiry of the Additional Acceptance Period 

 

	 	(i)	not to dispose over the Shares held by them to an individual third party, to a person affiliated with such individual third party in the sense of Secs. 15
et seq. of the Geman Stock Corporation Act, or to a person which qualifies as a “person acting in concert” with such individual third party in the sense of Sec. 2 para. 5 sentence 1 of the German Securities
Acquisition and Takeover Act (with the disposal of Shares via a stock exchange or to several third parties being permitted), 

  

	 	(ii)	not to accept a tender offer with regard to the Shares by any such party, and 

 

	 	(iii)	not to undertake vis-à-vis any such party to accept a tender offer with regard to the Shares, if and as long as (y) the management board and
the supervisory board of the Company do not approve such tender offer (i.e. in a press release or in their reasoned opinion according to Sec. 27 para. 1 of the German Securities Acquisition and Takeover Act recommend to reject the
offer, and do not withdraw such disapproval in a subsequent reasoned opinion), and (z) (1) the current members of the W.E.T. Management Board remain in their offices, (2) no further financial liabilities are taken up by
the Company, (3) the dividend policy of the Company is not materially changed or amended (except for in accordance with the Domination and Profit Transfer Agreement or as indicated in Section 3 No. 1 above), and
(4) no disposal of essential subsidiaries or business units is announced. 

 Amerigon will procure that
all persons affiliated with it in the sense of Secs. 15 et seq. of the German Stock Corporation Act, in particular, the Bidder will comply with the obligations pursuant to this Sec. IV.5.

 V. 
 FSA, Cartel Clearance 
  

	1.	The Bidder and, subject to the Legal Requirements and as long as the Support Conditions are satisfied, the Company will make all necessary filings, applications and
announcements or statements vis-à-vis the FSA, in order to obtain approval of the Offer Document and to carry out and accomplish the Transaction. 

  

	2.	The Parties will co-operate and make commercially reasonable efforts to obtain all necessary anti-trust approvals in a timely manner, in particular US anti-trust
approval by the Federal Trade Commission (FTC) or the U.S. Department of Justice, as the case may be, and for that purpose undertake to provide all necessary data, documents and other relevant information. 

 

	3.	If and to the extent the granting of anti-trust approval, in any relevant jurisdiction, is made subject to conditions or impositions (Bedingungen oder Auflagen)
by the competent anti-trust authority, and these conditions and impositions must be satisfied by the Bidder or by persons affiliated with the Bidder in the sense of Secs. 15 et seq. of the German Stock Corporation Act, the Bidder shall
have the option, and shall consider in good faith, to satisfy these conditions or impositions at its own expense and risk or to instruct the respective affiliated person to satisfy the conditions and impositions correspondingly. For the avoidance of
doubt, it is hereby clarified that (i) the aforementioned obligation to satisfy conditions or impositions is not incumbent on the Company or persons affiliated with the Company in the sense of Secs. 15 et seq. of the German
Stock Corporation Act; provided, however, that (y) the Company shall nevertheless remain obligated under para. 2 above concerning cooperation in connection with efforts to obtain all anti-trust approvals and (z) if the Company or
persons affiliated with the Company in the sense of Secs. 15 et seq. of the German Stock Corporation Act are requested in connection with any such anti-trust approval to pay or commit to pay any material amount of cash or other
consideration, the Bidder shall be given the opportunity to make such payments or commitment on behalf of the Company or affiliated persons, and (ii) in no event shall the obligation of the Bidder under this section apply to such
conditions or impositions which (y) are economically not reasonable (wirtschaftlich unzumutbar) to the Bidder or the respective affiliated persons or (z) alter the fundamental nature of the Transaction (including, but not limited
to, requiring a sale, divestiture or other disposal of any assets or business). 

 VI. 

Term, Termination 
  

	1.	This Agreement shall enter into force as of the day of its execution and shall have a duration until the earlier of (i) 18 months from the date hereof and

	 	1.1	by either Party if the SPA is not entered into at the latest on 28 February 2011 (the “Target Date”),

the Offer Document to the FSA by the Tender Offer Submission Date at the latest, (iii) the Bidder has not published the Offer Document by the Offer Publication Date at the latest, (iv) insolvency proceedings are opened over

(ii) insolvency proceedings are opened over the assets of the Company or (iii) the opening of insolvency proceedings over the assets of the Company is rejected due to lack of sufficient funds.

Agreement and except that the duties and obligations of the Parties under Secs. VII., VIII. and IX. below (“Confidentiality”, “Notices” and “Miscellaneous”) remain unaffected; provided,
however, that if termination is declared by one Party because of the breach of this Agreement by another Party, or because one or more of the conditions to the terminating Party’s obligations under this Agreement have not been satisfied as a
result of another Party’s failure to comply with its obligations under this Agreement, the terminating Party’s right to pursue all legal remedies will survive such termination unimpaired. 

 

	3.	In the event of termination of this Agreement each Party shall deliver to the respective other Party all documents, working papers and other materials furnished to it
by the respective other Party in connection with the Transaction, irrespective of whether such materials have been furnished before or after the date of this Agreement.

does not apply to 

  

	 	(i)	 such publications, announcements and ad hoc-announcements to which a Party is obliged by mandatory law, in court proceedings,
administrative proceedings or other proceedings based on mandatory law or regulations (the Parties expressly acknowledge that Amerigon and/or the Bidder are required under applicable law to

either Party in violation of this paragraph. 

  

	2.	Notwithstanding the aforementioned, the duties and obligations of each Party, in particular the duty of confidentiality, according to the Letter of Interest shall
remain unaffected.
