Ciba shall, within 10 business days after receipt of such notice, either (i) offer to acquire the Other Shares on terms at least as favorable to the Other Holders as those contemplated by such Third Party Offer (in which event Hexcel shall endorse such offer by Ciba rather than such Third Party Offer; PROVIDED, HOWEVER, that if Hexcel becomes the subject of another Third Party Offer that provides for greater currently realizable value to Hexcel's stockholders (including Ciba and the Ciba Entities) than such previously proposed Third Party Offer, Hexcel shall be free to pursue such newly proposed Third Party Offer; and PROVIDED, FURTHER, that such newly proposed Third Party Offer shall be subject to Ciba's rights pursuant to this Section 3.03(a)(i) and obligations pursuant to Section 3.03(a)(ii)) or (ii) confirm in writing that it will support, and at the appropriate time Ciba shall actually support, such Third Party Offer (or an alternative Third Party Offer providing greater currently realizable value to all Other Holders) by voting and causing each Ciba Entity to vote all its Voting Securities eligible to vote thereon in favor of such Third Party Offer or, if applicable, tendering or selling and causing each such Ciba Entity to tender or sell all its Voting Securities to the Person making such Third Party Offer. (b) In the event that Hexcel becomes the subject of a Third Party Offer, neither Ciba nor any of the Ciba Entities may support such Third Party Offer, vote in favor of such Third Party Offer or tender or sell its Voting Securities to the Person making such Third Party Offer unless such Third Party Offer is approved by (x) a majority of the Independent Directors acting solely in the interest of the Other Holders or (y) a majority in interest of the Other Holders in a Stockholder Vote solicited pursuant to a proxy statement containing the information required by Schedule 14A under the Exchange Act (it being understood that the Independent Directors shall, consistent with their fiduciary duties, be free to include in such proxy statement, if applicable, the reasons underlying any failure by them to approve such Third Party Offer by the requisite vote, including whether a fairness opinion was sought and any opinions or recommendations expressed in connection therewith). 16 (c) Notwithstanding Section 3.03(b), if Ciba has exercised the right to require Hexcel to solicit a Buyout Transaction pursuant to Section 5.01, Ciba and the Ciba Entities may vote in favor of or tender or sell their Voting Securities pursuant to any Third Party Offer made as a result of or during such solicitation so long as such Third Party Offer offers the same consideration to all Hexcel stockholders. Unless Hexcel shall have accepted another Third Party Offer providing at least equivalent value to all Hexcel stockholders, Hexcel shall not take any action to interfere with Ciba's right to vote in favor of or tender into such a Third Party Offer (it being understood that Hexcel shall remain free to pursue alternative Third Party Offers that provide for at least equivalent currently realizable value to Hexcel's stockholders (including Ciba and the Ciba Entities) as such previously proposed Third Party Offer). ARTICLE IV TRANSFER RESTRICTIONS SECTION 4.01. RESTRICTIONS. (a) Except in connection with a Third Party Offer that has been approved by the Independent Directors or the Other Holders in accordance with Section 3.03 or as provided in Section 3.03(c), Ciba shall not, and shall not permit any Ciba Entity, directly or indirectly, to sell, transfer or otherwise dispose of any Voting Securities except (i) transfers solely among Ciba and its wholly owned Subsidiaries, (ii) in accordance with the volume and manner-of-sale limitations of Rule 144 under the Securities Act (regardless of whether such limitations are applicable) and otherwise subject to compliance with the Securities Act or (iii) in a registered public offering or a non-registered offering subject to an applicable exemption from the registration requirements of the Securities Act, in the case of clauses (ii) and (iii), in a manner calculated to achieve a Broad Distribution. (b) Ciba shall not sell, transfer or otherwise dispose of any of the capital stock of any Ciba Entity, except to another direct or indirect wholly owned Subsidiary of Ciba; PROVIDED, HOWEVER, that nothing in this Agreement shall prohibit Ciba from effecting (x) a pro rata distribution to Ciba's stockholders or (y) a sale in a manner calculated to achieve a Broad Distribution of up to 20%, in each case, of the equity securities of a Ciba Entity if (1) such distribution or sale has a bona fide business purpose (other than the sale or distribution of Voting Securities), (2) the Voting Securities Beneficially Owned by such Ciba Entity do not constitute a material portion of the total assets of such Ciba Entity and (3) in the 17 case of clause (x), such Ciba Entity agrees in writing to be bound by the terms and provisions of this Agreement to the same extent that Ciba would be bound if it Beneficially Owned the Voting Securities Beneficially Owned by such Ciba Entity. Other than as permitted pursuant to the proviso in the immediately preceding sentence, Ciba shall not permit any Subsidiary of Ciba that is not a direct or indirect wholly owned Subsidiary of Ciba to become a Ciba Entity. SECTION 4.02. LEGENDS. (a) Except as set forth in paragraph (b) below, during the term of this Agreement all certificates representing Voting Securities Beneficially Owned by Ciba shall bear an appropriate restrictive legend indicating that such Voting Securities are subject to restrictions pursuant to this Agreement and that such Voting Securities were not issued pursuant to a public offering registered pursuant to the Securities Act. (b) Upon any transfer or proposed transfer of Beneficial Ownership by Ciba or any Ciba Entity of any Voting Securities to any Person other than Ciba or a Ciba Entity that is permitted pursuant to this Agreement, Hexcel shall, upon receipt of timely notice and such certificates, opinions and other documentation as shall be reasonably requested by Hexcel, cause certificates representing such transferred Voting Securities to be issued not later than the time needed to effect such transfer (x) without any restrictive legend if upon consummation of such transfer such Voting Securities are no longer "restricted securities" as defined in Rule 144 under the Securities Act or (y) without any reference to this Agreement if upon consummation of such transfer such Voting Securities continue to be "restricted securities". SECTION 4.03. EFFECT. Any purported transfer of Voting Securities that is inconsistent with the provisions of this Article IV shall be null and void and of no force or effect. ARTICLE V EXTENSION AND TERMINATION SECTION 5.01. CIBA ELECTION. (a) If the percentage of the Total Voting Power of Hexcel Beneficially Owned by Ciba on any Election Date is 18 greater than 10% but less than 100%, Ciba shall take either of the following actions on such Election Date: (i) extend this Agreement for an additional two year period, in which case so long as Ciba Beneficially Owns 25% or more of the Total Voting Power of Hexcel, on one occasion during each such two-year period Ciba may require Hexcel to solicit in good faith a Buyout Transaction in which Ciba, the Ciba Entities and the Other Holders receive the same consideration per Voting Security (in which event the provisions of this Agreement shall continue in full force and effect until the consummation of such a Buyout Transaction); or (ii) undertake to sell a sufficient number of Voting Securities so that the percentage of the Total Voting Power of Hexcel Beneficially Owned by Ciba falls below 10% during the subsequent 18 months pursuant to one or more Requisite Distributions (in which event the provisions of this Agreement shall continue until the percentage of the Total Voting Power of Hexcel Beneficially Owned by Ciba falls below 10%). (b) If at any time in accordance with this Agreement the percentage of the Total Voting Power of Hexcel Beneficially Owned by Ciba is either (x) 10% or less or (y) 100%, this Agreement shall automatically terminate. (c) If either party to this Agreement is in breach of or violates any material obligation under this Agreement and fails to cure such breach or violation within 60 days after delivery of written notice from the other party specifying such breach or violation and requesting its cure, such other party may terminate its obligations under this Agreement. 19 ARTICLE VI MISCELLANEOUS SECTION 6.01.
