("Merger Sub") propose to enter into an Agreement and Plan of Merger, dated as of the date hereof (the "Merger Agreement"), providing for, among other things, a merger (the "Merger") of Merger Sub with and into Grantee; and WHEREAS, as a condition and inducement to Grantee's willingness to enter into the Merger Agreement, Grantee has requested that the Company agree, and the Company has agreed, to grant Grantee the Option (as defined below). NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein and in the Merger Agreement, the Company and Grantee agree as follows: 1. Capitalized Terms. Certain capitalized terms used in this Agreement are defined in Annex A hereto and are used herein with the meanings therein ascribed. Those capitalized terms used but not defined herein (including in Annex A hereto) that are defined in the Merger Agreement are used herein with the same meanings as ascribed to them therein; provided, however, that, as used in this Agreement, "Person" shall have the meaning specified in Sections 3(a)(9) and 13(d)(3) of the Exchange Act. 2. The Option. (a) Grant of Option. Subject to the terms and conditions set forth herein and in the Merger Agreement, the Company hereby grants to Grantee an irrevocable option (the "Option") to purchase up to 7,538,000 ordinary shares (as adjusted as set forth herein) of the Company (the "Option Shares") no nominal value (the "Shares"), held by the Company in its treasury (being 2.82% of the number of shares outstanding on February 14, 2000 before such issuance), at the Exercise Price (as defined below). (b) Exercise Price. The exercise price, as adjusted as set forth herein (the "Exercise Price") of the Option shall be equal to the closing sales price of the Shares on the HSE on the Notice Date (as defined in Section 2(d)(ii)). (c) Term. The Option shall be exercisable at any time and from time to time following the occurrence of an Exercise Event and shall remain in full force and effect until the earliest to occur of (i) the Effective Time, (ii) six months after the first occurrence of an Exercise Event (or if, at the expiration of such six months after the first occurrence of an Exercise Event, the Option cannot be exercised by reason of any applicable Order, Law or Regulation, 10 business days after such impediment to exercise shall have been removed, but in no event under this clause (ii) later than the first anniversary of the Exercise Event), (iii) the receipt by the Company of Grantee's consent to the Company's sale of the Option Shares pursuant to Section 6.21 of the Merger Agreement, (iv) the Company receiving the required approval of its shareholders of the Parent Stock Option Agreement, (v) termination of the Merger Agreement in accordance with its terms other than a termination with respect to which an Exercise Event shall occur and (vi) the date on which Grantee shall have received the Profit Cap pursuant to Section 5 (the "Option Term"). If the Option is not theretofore exercised, the rights and obligations set forth in this Agreement shall terminate at the expiration of the Option Term. "Exercise Event" shall mean (A) any of the events giving rise to the obligation of the Company to pay the Termination Fee under Section 9.3 of the Merger Agreement, (B) termination of the Merger Agreement by Grantee under Section 9.1(c)(iii) and (C) termination of the Merger Agreement by Grantee or the Company under Section 9.1(d)(iii) and a Takeover Proposal has been made and publicly announced or communicated to the Company's shareholders after the date of this Agreement and prior to the Parent Shareholder Meeting. (d) Exercise of Option. (i) Grantee may exercise the Option, in whole or in part, at any time and from time to time following the occurence of an Exercise Event during the Option Term. Notwithstanding the expiration of the Option Term, Grantee shall be entitled to purchase those Option Shares with respect to which it has exercised the Option in accordance with the terms hereof prior to the expiration of the Option Term. (ii) If Grantee wishes to exercise the Option, it shall send a written notice (an "Exercise Notice") (the date of which being herein referred to as the "Notice Date") to the Company no later than 2:00 p.m. (Helsinki time) specifying the total number of Option Shares it intends to purchase pursuant to such exercise; provided that the issuance of Option Shares pursuant to such Exercise Notice shall only be completed if (A) such purchase would not otherwise violate or cause the violation of applicable Law (including the Hart-Scott-Rodino Antitrust Improvements Act of 1976), (B) no Law or Regulation shall have been adopted or promulgated, and no Order shall be in effect, which prohibits delivery of such Option Shares (and the parties shall use their reasonable best efforts to have any such Order vacated or reversed), and (C) any prior notification to or approval of any other regulatory authority in the United States or elsewhere required in connection with such purchase shall have been made or obtained, other than those which if not made or obtained would not reasonably be expected to result in a significant detriment to the Company and its Subsidiaries taken as a whole. (iii) The delivery of, and payment for, the Option Shares to be purchased pursuant to an Exercise Notice delivered in accordance with Section 2(d)(ii) shall, to the extent reasonably possible pursuant to the rules and regulations of the HSE, be completed as a stock exchange trade using the settlement system of the HSE and shall be completed (the "Closing") on the third trading date of the HSE following the Notice Date or on such other date which shall be the settlement date in the settlement system of the HSE when the Notice Date is deemed to be the trade date (the "Closing Date"). In order to facilitate the completion of such delivery of, and payment for, the Option Shares as stock exchange trades, each party will use the services of a Finland based securities broker in effecting such trades. (iv) In the event the delivery of, and payment for, the Option Shares in respect of which an Exercise Notice has been given pursuant to subparagraph (ii) above cannot be completed in accordance with subparagraph (iii) above, the Closing Date for such delivery of, and payment for, the Option Shares shall be specified in such Exercise Notice or shall otherwise be specified by Grantee in writing and shall be a date nor earlier than three Business Days nor later than 15 Business Days from the Notice Date. In such case: (x) On each Closing Date, Grantee shall pay to the Company in immediately available funds by wire transfer to a bank account designated by the Company an amount equal to the Exercise Price multiplied by the number of Option Shares to be purchased on such Closing Date. (y) On each Closing Date, simultaneously with the delivery of immediately available funds as provided above, the Company shall deliver to Grantee, in Grantee's book- entry account in the Finnish Book-entry Securities System, such number of Shares representing the Option Shares to be purchased at such Closing, which Option Shares shall be duly authorized, validly issued, fully paid and nonassessable and free and clear of all Liens, and Grantee shall deliver to the Company its written agreement that Grantee will not offer to sell or otherwise dispose of such Option Shares in violation of applicable Law or the provisions of this Agreement. (v) If the Closing cannot be effected by reason of a restriction set forth in Clause (A), (B) or (C) of the proviso in Section 2(d)(ii), the Closing Date shall be extended to the tenth Business Day following the expiration or termination of such restriction. Without limiting the foregoing, if prior notification to, or Authorization of, any Governmental Entity is required in connection with the purchase of such Option Shares by virtue of the application of such Law, Regulation or Order, Grantee and, if applicable, the Company shall promptly file the required notice or application for Authorization and Grantee, with the cooperation of the Company, shall expeditiously process the same. (vi) Notwithstanding Section 2(d)(v), if the Closing Date shall not have occurred by the first anniversary of the first occurrence of an Exercise Event as a result of one or more restrictions imposed by the application of any Law, Regulation or Order, the exercise of the Option effected on the Notice Date shall be deemed to have expired. 3. Adjustment Upon Changes in Capitalization, Etc. (a) In the event of any change in the Shares by reason of stock dividend, stock split, split-up, combination, reclassification, recapitalization, exchange of shares, dividend, dividend payable in any other securities or similar event, the type and number of Shares or securities subject to the Option shall be adjusted appropriately, and proper provision shall be made in the agreements governing such transaction, so that Grantee shall receive upon exercise of the Option the same class and number of outstanding shares or other securities or property that Grantee would have received in respect of the Shares if the Option had been exercised immediately prior to such event, or the record date therefor, as applicable. (b) Without limiting the parties' relative rights and obligations under the Merger Agreement, in the event that the Company enters into an agreement (i) to consolidate with or merge into any person, other than Grantee or one of its Subsidiaries, and the Company will not be the continuing or surviving corporation in such consolidation or merger, (ii) to permit any Person, other than Grantee or one of its Subsidiaries, to merge into the Company and the Company will be the continuing or surviving corporation, but in connection with such merger, the ordinary shares of the Company outstanding immediately prior to the consummation of such merger will be changed into or exchanged for stock or other securities of the Company or any other Person or cash or any other property, or (iii) to sell or otherwise transfer all or substantially all of its assets to any Person, other than Grantee or one of its Subsidiaries, then, and in each such case, the agreement governing such transaction will make proper provision so that the Option will, upon the consummation of any such transaction and upon the terms and conditions set forth herein, be converted into, or exchanged for, an option with identical terms appropriately adjusted to acquire the number and class of shares or other securities or property that Grantee would have received in respect of Option Shares had the Option been exercised immediately prior to such consolidation, merger, sale or transfer or the record date therefor, as applicable. The Company shall take such steps in connection with such consolidation, merger, liquidation or other such transaction as may be reasonably necessary to assure that the provisions hereof shall thereafter apply as nearly as possible to any securities or property thereafter deliverable upon exercise of the Option. 4. Purchase Not For Distribution. Grantee hereby represents and warrants to the Company that any Option Shares or other securities acquired by Grantee upon exercise of the Option will not be taken with a view to the public distribution thereof and will not be transferred or otherwise disposed of except in a transaction registered or exempt from registration under the Securities Act. 5. Profit Limitation. (a) Notwithstanding any other provision of this Agreement in no event shall Grantee's Total Profit exceed the Profit Cap and, if it otherwise would exceed such amount, Grantee, at its sole election, shall either (i) pay cash or other consideration to the Company, (ii) reduce the number of Shares subject to the Option or (iii) undertake any combination thereof, so that Grantee's Total Profit shall not exceed the Profit Cap after taking into account the foregoing actions. (b) Notwithstanding any other provision of this Agreement, this Stock Option may not be exercised for a number of Option Shares that would, as of any Notice Date, result in a Notional Total Profit of more than the Profit Cap, and, if exercise of the Option otherwise would exceed the Profit Cap, Grantee, at its sole option, may (in addition to the actions specified in Section 5(a)) (i) reduce the number of Option Shares subject to the Option or (ii) increase the Exercise Price for that number of Option Shares set forth in the Exercise Notice so that the Notional Total Profit shall not exceed the Profit Cap; provided, however, that nothing in this sentence shall restrict any exercise of the Option otherwise permitted by this Section 5(b) on any subsequent date at the Exercise Price set forth in Section 2(b) if such exercise would not then be restricted under this Section 5(b). (c) Notwithstanding any other provision of this Agreement, nothing in this Agreement shall affect the ability of Grantee to receive, nor relieve the Company's obligation to pay, any Termination Fee provided for in Section 9.3 of the Merger Agreement; provided that if and to the extent the Total Profit received by Grantee would exceed the Profit Cap following receipt of such payment, Grantee shall be obligated to promptly comply with the terms of Section 5(a). (d) For purposes of Section 5(a) and clause (ii) of the definition of Total Profit, the value of any Option Shares delivered by Grantee to the Company shall be the Applicable Price of such Option Shares. 6. Additional Covenants of the Company. (a) If the Shares or any other securities then subject to the Option are then listed on the HSE, the Company, upon the occurrence of an Exercise Event, will promptly file an application to list on the HSE the Shares or other securities then subject to the Option, following the due issuance thereof and will use all reasonable efforts to cause such listing application to be approved as promptly as practicable. (b) The Company will use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to permit the exercise of the Option in accordance with the terms and conditions hereof, as soon as practicable after the date hereof, including making any appropriate filing pursuant to the HSR Act and any other applicable law, supplying as promptly as practicable any additional information and documentary material that may be requested pursuant to the HSR Act and any other applicable law, and taking all other actions necessary to cause the expiration or termination of the applicable waiting periods under the HSR Act as soon as practicable. (c) The Company agrees not to avoid or seek to avoid (whether by charter amendment or through reorganization, consolidation, merger, issuance of rights, dissolution or sale of assets, or by any other voluntary act) the observance or performance of any of the covenants, agreements or conditions to be observed or performed hereunder by it. (d) Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Agreement, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation of this Agreement, if mutilated, the Company will execute and deliver a new Agreement of like tenor and date. (e) The Company agrees that, during the Option Term, it shall not sell any of the Option Shares except to Grantee upon exercise of the Option or upon receipt of the consent of Grantee pursuant to Section 6.21 of the Merger Agreement. 7.
