AGREEMENT AND PLAN OF MERGER

This AGREEMENT AND PLAN OF MERGER (this “Agreement”), dated as of May 30, 2006, is made by and among BASF AKTIENGESELLSCHAFT, a stock corporation organized under the laws of the Federal Republic of Germany (“Parent”), IRON ACQUISITION CORPORATION, a Delaware corporation and a wholly owned Subsidiary of Parent (“Merger Sub”), and ENGELHARD CORPORATION, a Delaware corporation (the “Company”). Capitalized terms used in this Agreement and not otherwise defined shall have the meaning given to such terms in Section 9.03.

WHEREAS, Merger Sub has commenced a tender offer (the “Offer”) to purchase all of the issued and outstanding shares of common stock, par value $1.00 per share of the Company, including the associated Series A Junior Participating Preferred Stock Purchase Rights (collectively, the “Company Common Stock”) for a price of $39.00 per share of Company Common Stock (such amount or any greater amount per share of Company Common Stock paid pursuant to the Offer, the “Offer Price”), subject to any required withholding of Taxes, net to the seller in cash, and on the terms and subject to the conditions set forth in this Agreement;

WHEREAS, the Board of Directors of the Company has, on the terms and subject to the conditions set forth herein, approved the Offer and adopted this Agreement, and is recommending that the Company’s stockholders accept the Offer, tender their shares of Company Common Stock to Merger Sub and approve this Agreement;

WHEREAS, the respective Boards of Directors of Parent, Merger Sub and the Company have approved and declared advisable the merger of Merger Sub with and into the Company (the “Merger”), upon the terms and subject to the conditions set forth in this Agreement; and

WHEREAS, Parent, Merger Sub and the Company desire to make certain representations, warranties, covenants and agreements in connection with the Offer and the Merger and also to prescribe various conditions to the Offer and the Merger.

NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and agreements contained in this Agreement and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

ARTICLE I

The Merger

SECTION 1.01 The Offer.

(a) Provided that this Agreement shall not have been terminated in accordance with Section 8.01, as promptly as practicable and in any event within one Business Day following the date hereof (or such later date as the parties may mutually agree in writing), Merger Sub (i) shall amend the Offer to reflect the execution of this Agreement, (ii) shall file an amendment to its Schedule TO, which amendment shall include an amended offer to purchase,

form of transmittal letter, form of notice of guaranteed delivery and all other necessary documents and exhibits with the Securities and Exchange Commission (the “SEC”) and make all deliveries, filings, publications, mailings and telephonic notices required to be made in connection with the Offer under the Federal securities laws, including Regulations 14D and 14E of the Securities Exchange Act of 1934, as amended (including the rules and regulations promulgated thereunder, the “Exchange Act”) (such documents filed or required to be filed with the SEC and such other filings, deliveries, mailings and notices, collectively and together with any amendments, exhibits or supplements thereto, the “Offer Documents”) and (iii) shall use its reasonable best efforts to consummate the Offer. Parent will cause Merger Sub to accept for payment and pay for any shares of Company Common Stock tendered pursuant to the Offer, subject only to the condition that there shall be validly tendered and not withdrawn prior to the expiration of the Offer such number of shares of Company Common Stock that, when added to the shares of Company Common Stock already owned by Parent or any of its Subsidiaries, would constitute at least a majority of the shares of Company Common Stock outstanding determined on a Fully Diluted Basis on the date of expiration of the Offer (the “Minimum Condition”) and to the other conditions set forth in Annex I hereto (together with the Minimum Condition, collectively, the “Tender Offer Conditions”).

(b) Without the prior written consent of the Company, Merger Sub shall not (and Parent shall cause Merger Sub not to) decrease the Offer Price or change the form of consideration payable in the Offer, decrease the number of shares of Company Common Stock sought to be purchased in the Offer, impose additional conditions to the Offer or amend any other term of the Offer in a manner that is adverse to the holders of shares of Company Common Stock, except as provided in this Agreement. The Offer shall remain open until the date that is five Business Days after the amendment of the Offer (the “Expiration Date”), unless the period of time for which the Offer is open shall have been extended as may be required by applicable Law or in accordance with the immediately following sentence, in which event the term “Expiration Date” shall mean the latest time and date as the Offer, as so extended, may expire; provided, however, that Merger Sub may (or, at the Company’s option, if at least 80% of the outstanding shares of Company Common Stock on a Fully Diluted Basis have been tendered and accepted for payment by Merger Sub, shall) provide for a subsequent offering period after the Expiration Date, in accordance with Rule 14d-11 under the Exchange Act (including the obligations that Merger Sub immediately accept and promptly pay for all shares of Company Common Stock tendered during the initial offering period and immediately accept and promptly pay for any shares of Company Common Stock tendered during such subsequent offering period). If, at any Expiration Date, any of the Tender Offer Conditions are not satisfied or waived by Merger Sub, Merger Sub shall (and Parent shall cause Merger Sub to) extend the Offer from time to time, each such extension not to exceed such number of days that Merger Sub reasonably believes is necessary to cause the Tender Offer Conditions to be satisfied (but in any event not more than 15 Business Days for all such extensions, unless, in each case, the parties shall otherwise mutually agree in writing). Under no circumstances shall Parent or Merger Sub waive the Minimum Condition. Subject to the terms of the Offer and this Agreement and the satisfaction of the Tender Offer Conditions as of any Expiration Date, including the Minimum Condition, Parent will cause Merger Sub to accept for payment and pay for any and all shares of Company Common Stock validly tendered and not validly withdrawn pursuant to the Offer promptly after such Expiration Date, regardless of the number of shares of Company Common Stock tendered in the Offer (such date as Merger Sub shall be obligated to accept for payment any and all shares of Company Common Stock validly tendered and not validly withdrawn

pursuant to the Offer, the “Acceptance Date”). For the avoidance of doubt, and notwithstanding anything in this Agreement to the contrary, Merger Sub shall not (and Parent shall cause Merger Sub not to) accept for payment any shares of Company Common Stock tendered pursuant to the Offer unless the Minimum Condition shall have been satisfied.

(c) Each of Parent and Merger Sub, on the one hand, and the Company, on the other hand, agrees to correct promptly any information provided by it for use in the Offer Documents if and to the extent that it shall have become false or misleading in any material respect and Merger Sub further agrees to take all steps necessary to cause the Offer Documents as so corrected to be filed with the SEC and to be disseminated to stockholders of the Company, in each case, as and to the extent required by applicable Federal securities Laws. The Company and its counsel shall be given a reasonable opportunity to review and comment on the Offer Documents in advance of their filing with the SEC and dissemination to stockholders of the Company. Parent and Merger Sub shall provide to the Company and its counsel copies in writing of any comments and shall inform the Company of any oral comments that Parent, Merger Sub or their counsel may receive from the SEC or its staff with respect to the Offer Documents promptly after receipt of such comments. The Company and its counsel shall be given a reasonable opportunity to review any such written and oral comments and proposed responses.

SECTION 1.02 Company Actions.

(a) The Company shall, after affording Parent and its counsel a reasonable opportunity to review and comment thereon, file with the SEC, as promptly as practicable on the date of the filing by Parent and Merger Sub of the Offer Documents, an amendment to its Solicitation/Recommendation Statement on Schedule 14D-9 (together with the existing statement and any subsequent amendments or supplements thereto, the “Schedule 14D-9”) reflecting the recommendation of the Company’s Board of Directors that holders of shares of Company Common Stock tender their shares into the Offer, and shall disseminate the Schedule 14D-9 as required by Rule 14d-9 promulgated under the Exchange Act. The Schedule 14D-9 will set forth that the Company’s Board of Directors has (i) determined by unanimous vote of all its members that each of the transactions contemplated hereby, including each of the Offer and the Merger, is fair to and in the best interests of the Company and its stockholders, (ii) approved the Offer and the Merger and this Agreement in accordance with the Delaware General Corporation Law (“DGCL”) and (iii) recommended acceptance and approval of the Offer and adoption of this Agreement by the Company’s stockholders; provided, however, that Parent and Merger Sub agree that such recommendations and the Schedule 14D-9 may be modified in a manner adverse to Parent and Merger Sub or withdrawn after the date hereof if, but only if, after consultation with its outside counsel, the Board of Directors determines that such action is advisable in connection with its fiduciary duties under applicable Law.

(b) Each of the Company, on the one hand, and Parent and Merger Sub, on the other hand, agrees to correct promptly any information provided by it for use in the Schedule 14D-9 if and to the extent that it shall have become false or misleading in any material respect and the Company further agrees to take all steps necessary to cause the Schedule 14D-9 as so corrected to be filed with the SEC and to be disseminated to stockholders of the Company, in each case, as and to the extent required by applicable Federal securities Laws. The Company

shall provide to Parent and its counsel copies in writing of any comments and shall inform Parent of any oral comments that the Company or its counsel may receive from the SEC or its staff with respect to the Schedule 14D-9 promptly after receipt of such comments. Parent and its counsel shall be given a reasonable opportunity to review any such written and oral comments and proposed responses.

(c) In connection with the Offer, the Company will promptly furnish Merger Sub with mailing labels, security position listings, any available non-objecting beneficial owner lists and any available listing or computer list containing the names and addresses of the record holders of the Company Common Stock as of the most recent practicable date and shall furnish Merger Sub with such additional available information (including, but not limited to, updated lists of holders of the Company Common Stock and their addresses, mailing labels and lists of security positions and non-objecting beneficial owner lists) and such other assistance as Merger Sub or its agents may reasonably request in communicating the Offer to the Company’s record and beneficial stockholders. Subject to the requirements of applicable Law, and except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Merger, Parent, Merger Sub and their Affiliates, associates, agents and advisors shall keep such information confidential and use the information contained in any such labels, listings and files only in connection with the Offer and the Merger and, should the Offer terminate or if this Agreement shall be terminated, will destroy all copies of such information then in their possession.

SECTION 1.03 Directors.

(a) Promptly upon the purchase of and payment for any shares of Company Common Stock by Merger Sub pursuant to the Offer which represent at least a majority of the shares of Company Common Stock outstanding on a Fully Diluted Basis and at all times thereafter and subject to Section 1.03(b), Merger Sub shall be entitled to elect such number of directors, rounded up to the next whole number, on the Company’s Board of Directors as is equal to the product of the total number of directors on the Company’s Board of Directors (giving effect to the directors elected or designated by Merger Sub pursuant to this sentence) multiplied by the percentage that the aggregate number of shares of Company Common Stock beneficially owned by Merger Sub and any of its Affiliates bears to the total number of shares of Company Common Stock then outstanding (such directors which Merger Sub is entitled to elect pursuant to this sentence, the “Merger Sub Designees”). The Company shall, upon Merger Sub’s request at any time following the purchase of and payment for shares of Company Common Stock pursuant to the Offer which represent at least a majority of the shares of Company Common Stock outstanding on a Fully Diluted Basis, take such reasonable actions, including promptly filling vacancies or newly created directorships on the Company’s Board of Directors, promptly increasing the size of the Company’s Board of Directors and/or promptly requesting the resignations of such number of its incumbent directors as are necessary to enable the Merger Sub Designees to be so elected or designated to the Company’s Board of Directors, and shall use its best efforts to cause the Merger Sub Designees to be so elected or designated at such time. The Company’s obligations under this Section 1.03(a) shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. The Company shall promptly upon execution of this Agreement take all actions required pursuant to Section 14(f) and Rule 14f-1 in order to fulfill its obligations under this Section 1.03(a), including mailing to stockholders the

information required by Section 14(f) and Rule 14f-1 as is necessary to enable the Merger Sub Designees to be elected or designated to the Company’s Board of Directors. Merger Sub shall supply the Company with, and be solely responsible for, information with respect to the Merger Sub Designees and Parent’s and Merger Sub’s respective officers, directors and Affiliates to the extent required by Section 14(f) and Rule 14f-1.

(b) In the event that Merger Sub’s designees are elected or designated to the Company’s Board of Directors pursuant to Section 1.03(a), then, until the Effective Time, the Company and Parent shall cause the Company’s Board of Directors to maintain as directors two directors who are members of the Company’s Board of Directors on the date hereof (the “Continuing Directors”); provided, however, that if any Continuing Director is unable to serve due to death, disability or resignation, the remaining Continuing Director shall be entitled to elect or designate another person to fill such vacancy, and such person shall be deemed to be a Continuing Director for purposes of this Agreement. If no Continuing Director then remains, the other directors shall designate two persons to fill such vacancies and such persons shall be deemed Continuing Directors for all purposes of this Agreement. Notwithstanding anything to the contrary contained herein, neither Parent nor Merger Sub shall take any action to cause any Continuing Director to be removed for cause. Notwithstanding anything in this Agreement to the contrary, the affirmative vote of a majority of the Continuing Directors shall (in addition to the approval rights of the Board of Directors or the stockholders of the Company as may be required by the Restated Certificate of Incorporation of the Company (as amended, the “Company Articles”), the bylaws of the Company (as amended, the “Company Bylaws,” and together with the Company Articles, the “Company Governing Documents”) or applicable Law) be required (i) for the Company to amend or terminate this Agreement, (ii) to exercise or waive any of the Company’s rights, benefits or remedies hereunder, (iii) to amend the Company Governing Documents or (iv) to take any other action of the Company’s Board of Directors under or in connection with this Agreement. The Continuing Directors shall have the authority to retain such counsel and other advisors at the expense of the Company as determined appropriate by the Continuing Directors and shall have the authority to institute any action on behalf of the Company to enforce the performance of this Agreement.

SECTION 1.04 The Merger. Upon the terms and subject to the conditions set forth in this Agreement and in accordance with the DGCL, Merger Sub shall be merged with and into the Company at the Effective Time. Following the Effective Time, the separate corporate existence of Merger Sub shall cease, and the Company shall continue as the surviving corporation in the Merger (the “Surviving Corporation”) and shall succeed to and assume all the rights and obligations of Merger Sub in accordance with the DGCL.

SECTION 1.05 Closing. The closing of the Merger (the “Closing”) will take place at 10:00 a.m. on a date to be specified by the parties (the “Closing Date”), which shall be no later than the second Business Day after satisfaction or waiver of the conditions set forth in Article VII (other than those conditions that by their terms are to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions), at the offices of Shearman & Sterling LLP, 599 Lexington Avenue, New York, New York, unless another date or place is agreed to in writing by the parties hereto.

SECTION 1.06 Effective Time. Subject to the provisions of this Agreement, as soon as practicable on the Closing Date, the parties shall file a certificate of merger (the “Certificate of Merger”) executed in accordance with the relevant provisions of the DGCL and shall make all other filings or recordings required under the DGCL. The Merger shall become effective at such time as the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware, or at such other time as Parent and the Company shall agree and shall specify in the Certificate of Merger (the time the Merger becomes effective being the “Effective Time”).

SECTION 1.07 Effects of the Merger. The Merger shall have the effects set forth in Section 2.01 below and in the DGCL (including in Section 259 of the DGCL).

SECTION 1.08 Certificate of Incorporation and Bylaws.

(a) The Company Articles shall be the Certificate of Incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law; provided, however, that, at the Effective Time, the Certificate of Incorporation of the Surviving Corporation shall be amended in its entirety to be identical to the Certificate of Incorporation of Merger Sub in effect immediately prior to the Effective Time, except that Article I thereof shall read as follows: “The name of the corporation is Engelhard Corporation.”

(b) The Bylaws of the Merger Sub, as in effect immediately prior to the Effective Time, shall be the Bylaws of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law.

SECTION 1.09 Directors. The directors of Merger Sub immediately prior to the Effective Time shall be the directors of the Surviving Corporation, each of such directors to hold office, subject to the applicable provisions of the Certificate of Incorporation and Bylaws of the Surviving Corporation, until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be.

SECTION 1.10 Officers. The officers of the Company immediately prior to the Effective Time shall be the officers of the Surviving Corporation, such officers to hold office, subject to the applicable provisions of the Certificate of Incorporation and Bylaws of the Surviving Corporation, until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be.

ARTICLE II

Effect of the Merger on the Capital Stock of the
Constituent Corporations

SECTION 2.01 Effect on Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of Company Common Stock or any shares of capital stock of Merger Sub:

(a) Common Stock of Merger Sub. Each issued and outstanding share of common stock of Merger Sub shall be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $.01 per share, of the Surviving

Corporation with the same rights, powers and privileges as the shares so converted and shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

(b) Cancellation of Stock. Each share of Company Common Stock held by the Company as treasury stock (other than shares, if any, in any Employee Benefit Plans) or owned by Parent or any of its Subsidiaries immediately prior to the Effective Time shall automatically be canceled and retired and shall cease to exist and no payment shall be made with respect thereto.

(c) Company Common Stock; Determination of Merger Consideration. Each share of Company Common Stock outstanding as of the Effective Time (other than the Dissent Shares and shares cancelled pursuant to Section 2.01(b) and excluding shares of Company Common Stock owned by Parent, Merger Sub or any other wholly owned direct or indirect Subsidiary of Parent), by virtue of the Merger, shall be converted into a right to receive the Offer Price in cash, without interest, less the per share amount of any dividend that has, after the date hereof and prior to the Effective Time, been paid to, or become payable to, holders of Company Common Stock by the Company (the “Per Share Merger Consideration,” the aggregate amount in cash into which all shares of Company Common Stock may be converted pursuant to this Section 2.01, the “Aggregate Merger Consideration”).

(d) Dissenters’ Rights. Notwithstanding anything in this Agreement to the contrary, shares of Company Common Stock that are outstanding immediately prior to the Effective Time, that are not held by Parent, Merger Sub or any other wholly owned direct or indirect Subsidiary of Parent, and that are held by any Person who is entitled to dissent from the Merger pursuant to Section 262 of the DGCL (the “Dissenters’ Rights Statute”), who did not vote in favor of the Merger or consent thereto in writing and who complies in all other respects with the Dissenters’ Rights Statute (such shares, “Dissent Shares”) shall not be converted into a right to receive the Per Share Merger Consideration as provided in Section 2.01(c), but rather the holders of Dissent Shares shall be entitled to the right to receive payment of the fair value of such Dissent Shares in accordance with the Dissenters’ Rights Statute; provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to receive payment of the fair value under the Dissenters’ Rights Statute, then the right of such holder to be paid the fair value of such holder’s Dissent Shares shall cease and such Dissent Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for, the right to receive the Per Share Merger Consideration, without interest, as provided in Section 2.01(c). The Company shall give prompt notice to Parent of any written demands and any other instruments served pursuant to the Dissenters’ Rights Statute received by the Company relating to rights of appraisal under the Dissenters’ Rights Statute, and Parent shall have the right to direct all negotiations and proceedings with respect to such demands. Except with the prior written consent of Parent, the Company shall not make any payment with respect to, or offer to settle or settle, any such demands. Each holder of Dissent Shares who becomes entitled to payment for such shares pursuant to the Dissenters’ Rights Statute shall receive payment therefor from the Surviving Corporation in accordance with the Dissenters’ Rights Statute.

SECTION 2.02 Payment to Company Stockholders.

(a) Prior to the Effective Time, Merger Sub shall designate a bank or trust company to act as agent (the “Exchange Agent”) for the purpose of exchanging for the Merger Consideration (i) certificates representing Company Common Stock (the “Certificates”) or (ii) uncertificated Company Common Stock (the “Uncertificated Shares”). At the Effective Time, Parent shall deposit with the Exchange Agent an amount in immediately available funds equal to the Aggregate Merger Consideration to be paid in respect of all of the Certificates and the Uncertificated Shares. Promptly after the Effective Time, Parent shall send, or shall cause the Exchange Agent to send, to each holder of Company Common Stock at the Effective Time a letter of transmittal and instructions (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates or transfer of the Uncertificated Shares to the Exchange Agent) for use in such exchange.

(b) Each holder of shares of Company Common Stock that have been converted into the right to receive the Merger Consideration shall be entitled to receive, upon (i) surrender to the Exchange Agent of a Certificate, together with a properly completed letter of transmittal or (ii) receipt of an “agent’s message” by the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, the Merger Consideration, without interest, payable for each Company Common Share represented by a Certificate or for each Uncertificated Share. Until so surrendered or transferred, as the case may be, each such Certificate or Uncertificated Share shall represent after the Effective Time for all purposes only the right to receive such Merger Consideration.

(c) If any portion of the applicable Merger Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate or the transferred Uncertificated Share is registered, it shall be a condition to such payment that (i) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Uncertificated Share shall be properly transferred and (ii) the Person requesting such payment shall pay to the Exchange Agent any transfer or other Taxes required as a result of such payment to a Person other than the registered holder of such Certificate or Uncertificated Share or establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(d) After the Effective Time, there shall be no further registration of transfers of shares of Company Common Stock. If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Surviving Corporation, they shall be canceled and exchanged for the Merger Consideration provided for, and in accordance with the procedures set forth, in this Article II.

(e) Any portion of the Merger Consideration deposited with the Exchange Agent pursuant to Section 2.02(a) (and any interest or other income earned thereon) that remains unclaimed by the holders of Company Common Stock one year after the Effective Time shall be returned to Parent, upon demand, and any such holder who has not exchanged such Company Common Stock for the Merger Consideration in accordance with this Section 2.02 prior to that time shall thereafter look only to Parent and the Surviving Corporation for payment of the Merger Consideration in respect of such Company Common Stock without any interest thereon.

Notwithstanding the foregoing, Parent, the Surviving Corporation and the Exchange Agent shall not be liable to any holder of Company Common Stock for any amount paid to a public official pursuant to applicable abandoned property, escheat or similar Laws.

(f) Any portion of the Merger Consideration deposited with the Exchange Agent pursuant to Section 2.02(a) to pay for Company Common Stock, for which dissenters’ rights have been perfected and have not been withdrawn or lost 30 days after the Effective Time, shall be returned to Parent, upon demand.

(g) Notwithstanding anything to the contrary contained herein, the Exchange Agent, Parent or the Company shall be entitled to deduct and withhold from the consideration otherwise payable (i) to any holder of shares of Company Common Stock pursuant to this Agreement, (ii) to any Person designated to receive Merger Consideration pursuant to Section 2.02(c) or (iii) to any Person pursuant to Section 2.03 hereof such amounts as may be required to be deducted and withheld with respect to the making of such payment under the Internal Revenue Code of 1986, as amended, and the rules and regulations promulgated thereunder, or under any provision of state, local or foreign tax Law; provided, that no amount shall be withheld or deducted under any provisions of foreign tax Law, except to the extent that a person is subject to such withholding or deduction as a result of a connection between such person and the foreign jurisdiction that imposes such withholding or deduction (other than a connection arising solely from the receipt of consideration pursuant to this Agreement). To the extent that amounts are so withheld and paid over to the appropriate taxing authority by the Exchange Agent, Parent or the Company, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Company Common Stock in respect of which such deduction and withholding was made.

SECTION 2.03 Treatment of Options, Restricted Stock and other Equity Awards.

(a) Upon the consummation of the Offer, each employee and director stock option to purchase Company Common Stock outstanding under any stock option or compensation plan or arrangement of the Company shall, with no action on the part of the Company or holder thereof, become fully vested. At or immediately prior to the Effective Time, the Company will cause any necessary action to be taken to cause each such stock option to be canceled and the Company shall pay each holder of any such option, at the Effective Time, for each such option surrendered an amount in cash determined by multiplying (i) the excess, if any, of the Merger Consideration over the applicable exercise price of such option by (ii) the number of shares of Company Common Stock such holder could have purchased (assuming full vesting of all options) had such holder exercised such option in full immediately prior to the Effective Time.

(b) Upon the consummation of the Offer, each share of Company Common Stock subject to restrictions on transfer and/or forfeiture outstanding under any stock or compensation plan or arrangement of the Company shall, with no action on the part of the Company or holder thereof, become fully vested. In addition, upon consummation of the Offer, the Company will cause any necessary action to be taken to cause each restricted stock unit and each other deferred right to receive in the future shares or cash measured in reference to shares of

Company Common Stock granted pursuant to the Company’s deferred compensation plans to vest and the maximum amount of shares of Company Common Stock deliverable thereunder will be delivered as provided in the applicable plan pertaining thereto.

(c) Prior to the Effective Time, the Company shall take all necessary action (i) such that the disposition by each member of the Board of Directors and each employee of the Company that is subject to Section 16 of the Exchange Act of Company Common Stock, options to purchase Company Common Stock, restricted stock units and other deferred rights to receive shares or cash measured in reference to shares of Company Common Stock, in each case, pursuant to the transactions contemplated by this Agreement, shall be exempt from Section 16(b) of the Exchange Act pursuant to Rule 16b-3 thereunder and (ii) in order to give effect to the transactions contemplated by Sections 2.03(a) and 2.03(b).

SECTION 2.04 Adjustments.

SECTION 8.02 Intentionally Omitted.

(a) the Minimum Condition shall not have been satisfied immediately prior to the expiration date of the Offer (as it may be extended in accordance with the terms of this Agreement); or

(b) on or after the date of the Agreement and prior to the expiration date of the Offer (as it may be extended in accordance with the terms of this Agreement), any of the following conditions shall have occurred:

(i) any Restraints shall be in effect and not removed making illegal, restraining or prohibiting the making of the Offer, the acceptance for payment of any Company Common Stock by Parent, Merger Sub or any other Affiliate of Parent, or the consummation of any other transaction contemplated by this Agreement;

(ii) the representations and warranties of the Company set forth in the Agreement shall not be true and correct (without giving effect to any materiality or Company Material Adverse Effect qualification contained therein except with respect to Section 3.07(a)) as of the Expiration Date of the Offer (except to the extent that any such representation or warranty refers specifically to a particular date, in which case such representation or warranty shall be true and correct as of such date) except where the failure to be so true and correct, individually or in the aggregate, does not and would not reasonably be expected to have a Company Material Adverse Effect;

(iii) the Company shall have failed to perform any obligation or to comply with any agreement or covenant of the Company to be performed or complied with by it under the Agreement, except where the failure to perform or comply, individually or in the aggregate, does not have a Company Material Adverse Effect or would not reasonably be likely to have a material adverse effect on Merger Sub’s ability to purchase the shares of Company Common Stock pursuant to the Offer;

(iv) it shall have been publicly disclosed, or Parent or Merger Sub shall have otherwise learned, that beneficial ownership (determined for the purposes of this paragraph as set forth in Rule 13d-3 promulgated under the Exchange Act) of 15% or more of the then-outstanding Company Common Stock has been acquired by any Third Party and the Company shall have terminated the Company Rights Agreement in connection therewith or taken any action to amend or modify the Company Rights Agreement to exempt such Third Party from the Company Rights Agreement or render it inapplicable to such Third Party;

(v) there shall have occurred (A) a declaration of a banking moratorium or any suspension of payments in respect of banks in the United States or Germany or (B) any limitation (whether or not mandatory) by any government or Governmental Authority on the extension of credit by banks or other lending institutions that materially and adversely affects the ability of Merger Sub to consummate the Offer;

(vi) this Agreement shall have been terminated in accordance with its terms; or

(vii) Merger Sub and the Company shall have agreed that Merger Sub shall terminate the Offer or postpone the acceptance for payment of Company Common Stock thereunder.

The foregoing conditions are for the sole benefit of Parent and Merger Sub and may be asserted by Parent and Merger Sub regardless of the circumstances giving rise to any such condition and may be waived by Parent or Merger Sub (except for the Minimum Condition), in whole or in part, at any time and from time to time prior to the expiration of the Offer, in their respective sole discretion. The failure by Parent or Merger Sub at any time to exercise any of the foregoing rights will not be deemed a waiver of any such right, the waiver of any such right with respect to any particular facts and circumstances shall not be deemed a waiver with respect to any other facts and circumstances and each such right will be deemed an ongoing right that may be asserted at any time and from time to time.
