(i) any shares of Company Capital Stock held as treasury stock immediately prior to the Effective Time shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor; and

(ii) subject to Section  1.5(b) , each share of Company Capital Stock outstanding immediately prior to the Effective Time (excluding shares to be canceled pursuant to Section  1.5(a)(i) and excluding Dissenting Shares) shall be converted (and shall cease to exist) solely into the right to receive (A) Milan Depositary Shares, representing a number of Milan Ordinary Shares equal to the Exchange Ratio (the “ Share Consideration ”), and (B) one Milan CVR (together with the Share Consideration, the “ Merger Consideration ”); provided , however , that, notwithstanding anything to the contrary in this Agreement or the CVR Agreement, the number of Milan Ordinary Shares to be allotted and issued by Milan to the Depositary (and the corresponding number of Milan Depositary Shares to be issued by the Depositary) as Merger Consideration or pursuant to the CVR Agreement shall not, in the aggregate, exceed sixty-six point sixty-seven percent (66.67%) of the Milan Outstanding Shares (the “ Share Consideration Cap ”), and (i) if the aggregate number of Milan Ordinary Shares underlying the Milan Depositary Shares to be issued at Closing would otherwise exceed the Share Consideration Cap, the Exchange Ratio shall be appropriately adjusted so that the Share Consideration Cap is not exceeded and (ii) if, at any time following the Closing, the aggregate number of Milan Depositary Shares to be issued pursuant to the CVR Agreement would require the allotment and issuance of an aggregate number of Milan Ordinary Shares (underlying such Milan Depositary Shares) that, together with the aggregate number of Milan Ordinary Shares underlying the Milan Depositary Shares issued at Closing pursuant to this Agreement (collectively, the “ Total Share Consideration ”), would otherwise exceed the Share Consideration Cap, then the number of Milan Depositary Shares to be issued pursuant to the CVR Agreement shall be appropriately reduced so that the Total Share Consideration does not exceed the Share Consideration Cap.

(b) Within three (3) calendar days after the Delivery Date (the last day of such period, the “ Response Date ”), Milan shall have the right to dispute any part of the Net Cash Calculation by delivering a written notice to that effect to the Company (a “ Dispute Notice ”). Any Dispute Notice shall identify in reasonable detail and to the extent known the nature and amounts of any proposed revisions to the Net Cash Calculation.

(c) If, on or prior to the Response Date, Milan notifies the Company in writing that it has no objections to the Net Cash Calculation or, if prior to 8:00 p.m. (New York City Time) on the Response Date, Milan has failed to deliver a Dispute Notice as provided in Section  1.7(b) , then the Net Cash Calculation as set forth in the Net Cash Schedule shall be deemed to have been finally determined for purposes of this Agreement and to represent the Net Cash at the Cash Determination Time (the “ Final Net Cash ”) for purposes of this Agreement.

(d) If Milan delivers a Dispute Notice on or prior to 5:00 p.m. (New York City Time) on the Response Date, then Representatives of the Company and Milan shall promptly, and in no event later than one (1) calendar day after the Response Date, meet and attempt in good faith to resolve the disputed item(s) and negotiate an agreed-upon determination of Net Cash, which agreed upon Net Cash amount shall be deemed to have been finally determined for purposes of this Agreement and to represent the Final Net Cash for purposes of this Agreement.

(e) If Representatives of the Company and Milan are unable to negotiate an agreed-upon determination of Final Net Cash pursuant to Section  1.7(d) within two (2) calendar days after delivery of the Dispute Notice (or such other period as the Company and Milan may mutually agree upon), then any remaining disagreements as to the calculation of Net Cash shall be referred to Grant Thornton LLP or another independent auditor of recognized national standing mutually agreed upon by the Company and Milan (the “ Accounting Firm ”). The Company shall promptly deliver to the Accounting Firm all work papers and back-up materials used in preparing the Net Cash Schedule, and the Company and Milan shall use commercially reasonable efforts to cause the Accounting Firm to make its determination within five (5) calendar days of accepting its selection. Milan and the Company shall be afforded the opportunity to present to the Accounting Firm any material related to the unresolved disputes and to discuss the issues with the Accounting Firm; provided , however , that no such presentation or discussion shall occur without the presence of a Representative of each of Milan and the Company. The determination of the Accounting Firm shall be limited to the disagreements submitted to the Accounting Firm. The determination of the amount of Net Cash made by the Accounting Firm shall be made in writing delivered to each of the Company and Milan, shall be final and binding on the Company and Milan and shall be deemed to have been finally determined for purposes of this Agreement and to represent the Final Net Cash for purposes of this Agreement. The Parties shall delay the Closing until the resolution of the matters described in this Section  1.7(e) . The fees and expenses of the Accounting Firm shall be allocated between the Company and Milan in the same proportion that the disputed amount of the Net Cash that was unsuccessfully disputed by such Party (as finally determined by the Accounting Firm) bears to the total disputed amount of the Net Cash amount and such portion of the costs and expenses of the Accounting Firm borne by the Company and any other fees, costs or expenses incurred by the Company following the Delivery Date in connection with the procedures set forth in this Section  1.7(e) shall be deducted from the final determination of the amount of Net Cash. If this Section  1.7(e) applies as to the determination of the Final Net Cash described in Section  1.7(a) , upon resolution of the matter in accordance with this Section  1.7(e) , the Parties shall not be required to determine Net Cash again even though the Closing Date may occur later than the Anticipated Closing Date, except that either the Company or Milan may request a redetermination of the Final Net Cash if the Closing Date is more than twenty (20) calendar days after the Anticipated Closing Date.

1.8 Surrender of Certificates .

(a) Within 45 days from the date hereof, Milan shall appoint Citibank, N.A. or one of its Affiliates or, if Citibank N.A. and its Affiliates shall refuse to act, one or more banks or trust companies or other independent financial institutions (each of which institution and appointment shall be subject to the written consent of the Company, such consent not to be unreasonably withheld, conditioned or delayed) to act as: (i) depositary under the Deposit Agreement (the “ Depositary ”) in connection with the issuance of Milan Depositary Shares, and (ii) exchange agent in the Merger (the “ Exchange Agent ”) pursuant to an exchange agent agreement with the Exchange Agent, which agreement shall set forth the duties, responsibilities and obligations of the Exchange Agent consistent with the terms of this Agreement.

(b) At the Effective Time, (i) Milan shall allot, issue and deposit with the Depositary (or its designee), for the benefit of the holders of shares of Company Common Stock, such number of Milan Ordinary Shares as is equal to the Milan Depositary Shares issuable pursuant to Section  1.5(a) , inter alia, in exchange for shares of Company Capital Stock and (ii) the Depositary shall issue the Milan Depositary Shares comprising the Share Consideration. The Merger Consideration, and amounts paid and Milan Ordinary Shares issued pursuant to the CVR Agreement, are in consideration of the cancellation of Company Capital Stock pursuant to this Agreement and the issue of 999 further shares by HoldCo to Milan.

(c) Promptly after the Effective Time, the Parties shall cause the Exchange Agent to mail to the Persons who were record holders of shares of Company Capital Stock that were converted into the right to receive the Merger Consideration: (i) a letter of transmittal in customary form and containing such provisions as Milan may reasonably specify (including a provision confirming that delivery of Company Stock Certificates shall be effected, and risk of loss and title to Company Stock Certificates shall pass, only upon delivery of such Company Stock Certificates to the Exchange Agent); and (ii) instructions for effecting the surrender of Company Stock Certificates in exchange for the Merger Consideration. Upon surrender of a Company Stock Certificate to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Milan: (A) the holder of such Company Stock Certificate shall be entitled to receive in exchange therefor (i) the number of whole book-entry Milan Depositary Shares, and (ii) the number of Milan CVRs, in each case that such holder has the right to receive pursuant to the provisions of Section  1.5(a) ; and (B) the Company Stock Certificate so surrendered shall be canceled. Until surrendered as contemplated by this Section  1.8(c) , each Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive the Merger Consideration. If any Company Stock Certificate shall have been lost, stolen or destroyed, Milan may, in its discretion and as a condition precedent to the delivery of any Milan Depositary Shares or Milan CVRs, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an applicable affidavit with respect to such Company Stock Certificate and post a bond indemnifying Milan against any claim suffered by Milan related to the lost, stolen or destroyed Company Stock Certificate or any Milan Depositary Shares or Milan CVRs issued in exchange therefor as Milan may reasonably request.

7

(d) No dividends or other distributions declared or made with respect to Milan Depositary Shares, or Milan Ordinary Shares underlying such Milan Depositary Shares, with a record date after the Effective Time shall be paid to the holder of any unsurrendered Company Stock Certificate with respect to the Milan Depositary Shares that such holder has the right to receive in the Merger until such holder surrenders such Company Stock Certificate or provides an affidavit of loss or destruction in lieu thereof in accordance with this Section  1.8 (at which time such holder shall be entitled, subject to the effect of applicable abandoned property, escheat or similar laws, to receive all such dividends and distributions, without interest).

(e) Any Milan Depositary Shares that remain undistributed to holders of Company Stock Certificates as of the date that is 180 days after the Closing Date shall be delivered to Milan or a person nominated in writing by Milan upon demand and may be cancelled, and any holders of Company Stock Certificates who have not theretofore surrendered their Company Stock Certificates in accordance with this Section  1.8 shall thereafter look only to Milan for satisfaction of their claims for Milan Depositary Shares and any dividends or distributions with respect to Milan Depositary Shares. If any Company Stock Certificate has not been surrendered prior to the fifth anniversary of the Effective Time, or immediately prior to such earlier date on which the Merger Consideration, or any dividends or distributions, as contemplated by Section  1.8(d) , to which such Company Stock Certificate would otherwise entitle its holder would escheat to or become the property of any Governmental Authority, any such shares, cash, dividends or distributions in respect of such Company Stock Certificate shall, to the extent permitted by applicable Law, become the property of Milan, free and clear of all claims or interest of any Person previously entitled thereto, and no consideration or compensation shall be payable therefor.

(f) Each of the Exchange Agent, Milan and the Surviving Corporation shall be entitled to deduct and withhold from any consideration deliverable pursuant to this Agreement such amounts as are required to be deducted or withheld from such consideration under the Code or under any other applicable Law. To the extent such amounts are so deducted or withheld, and remitted to the appropriate Tax Authority, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

8

(g) No Party shall be liable to any holder of any Company Stock Certificate or to any other Person with respect to any Milan Depositary Shares (or dividends or distributions with respect thereto) or for any cash amounts delivered to any public official pursuant to any applicable abandoned property law, escheat law or similar Law.

1.9 Appraisal Rights .

(a) Notwithstanding any provision of this Agreement to the contrary, shares of Company Capital Stock that are outstanding immediately prior to the Effective Time and which are held by stockholders who have exercised and perfected appraisal rights for such shares of Company Capital Stock in accordance with the DGCL (collectively, the “ Dissenting Shares ”) shall not be converted into or represent the right to receive the Merger Consideration described in Section  1.5 attributable to such Dissenting Shares. Such stockholders shall be entitled to receive payment of the appraised value of such shares of Company Capital Stock held by them in accordance with the DGCL, unless and until such stockholders fail to perfect or effectively withdraw or otherwise lose their appraisal rights under the DGCL. All Dissenting Shares held by stockholders who shall have failed to perfect or who effectively shall have withdrawn or lost their right to appraisal of such shares of Company Capital Stock under the DGCL shall thereupon be deemed to be converted into and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration attributable to such Dissenting Shares upon their surrender in the manner provided in Section  1.5 .

(b) The Company shall give Milan prompt written notice of any demands by dissenting stockholders received by the Company, withdrawals of such demands and any other instruments served on the Company and any material correspondence received by the Company in connection with such demands. The Company shall not, without Milan’s prior written consent, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

1.10 Further Action . If, at any time after the Effective Time, any further action is determined by the Surviving Corporation to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of the Company, then the officers and directors of the Surviving Corporation shall be fully authorized, and shall use their and its commercially reasonable efforts (in the name of the Company, in the name of Merger Sub, in the name of the Surviving Corporation and otherwise) to take such action.

No such notice shall be deemed to supplement or amend the Company Disclosure Schedule or the Milan Disclosure Schedule for the purpose of (x) determining the accuracy of any of the representations and warranties made by the Company or Milan in this Agreement or (y) determining whether any condition set forth in Section  6 , 7 or 8 has been satisfied.

Such adjusting payment as may be required between the Parties to give effect to this Section  9.3(h) shall be made five (5) Business Days after the date on which the determination by the Tax Authority has been communicated to the party required to make the payment (together with such evidence of it as is reasonable in the circumstances to provide and, where subparagraph (i) applies, together with the provision of a valid VAT invoice) or, if later (in the case of subparagraph (i)) five (5) Business Days after the VAT is recovered or (in the case of subparagraph (ii)) five (5) Business Days before the VAT is required to be accounted for.

(h) If any Milestone Payment (or portion thereof) remains unclaimed by a Holder two (2) years after the applicable Milestone Payment Date (or immediately prior to such earlier date on which such Milestone Payment would otherwise escheat to or become the property of any Governmental Authority), such Milestone Payment (or portion thereof) will, to the extent permitted by applicable Law, become the property of Milan and will be transferred to Milan or a person nominated in writing by Milan (with written notice thereof from Milan to the Rights Agent), free and clear of all claims or interest of any Person previously entitled thereto, and no consideration or compensation shall be payable therefor.
