(b) Milan hereby appoints the Rights Agent to act as rights agent for Milan in accordance with the express terms and conditions set forth in this Agreement, and the Rights Agent hereby accepts such appointment.

Section 2.2 Non-transferable.

A Holder may not at any time Transfer CVRs, other than pursuant to a Permitted Transfer. Any attempted Transfer that is not a Permitted Transfer, in whole or in part, will be void ab initio and of no effect.

Section 2.3 No Certificate; Registration; Registration of Transfer; Change of Address.

(a) Holders’ rights and obligations in respect of CVRs derive solely from this Agreement; CVRs will not be evidenced by a certificate or other instrument.

(b) The Rights Agent will maintain an up-to-date register (the “CVR Register”) for the purposes of (i) identifying the Holders of CVRs, (ii) determining Holders’ entitlement to CVRs and (iii) registering the CVRs and Permitted Transfers thereof. The CVR Register will initially show one position for the Rights Agent representing all of the CVRs provided to the holders of shares of Company Common Stock held immediately prior to Closing. Neither Milan nor its Subsidiaries will have any responsibility or liability whatsoever to any person other than the Holders.

(c) Subject to the restriction on transferability set forth in Section 2.2, every request made to Transfer CVRs must be in writing and accompanied by a written instrument of Transfer, together with the signature guarantee of a guarantor institution which is a participant in a signature guarantee program approved by the Securities Transfer Association (a “signature guarantee”) and other requested documentation in a form reasonably satisfactory to the Rights Agent, duly executed and properly completed, as applicable, by the Holder or Holders thereof, or by the duly appointed legal representative, personal representative or survivor of such Holder or Holders, setting forth in reasonable detail the circumstances relating to the Transfer. Upon receipt of such written notice, the Rights Agent will, subject to its reasonable determination in accordance with its own internal procedures, that the Transfer instrument is in proper form and the Transfer, is a Permitted Transfer and otherwise complies on its face with the other terms and conditions of this Agreement, register the Transfer of the applicable CVRs in the CVR Register. All Transfers of CVRs registered in the CVR Register will be the valid obligations of Milan, evidencing the same right, and entitling the transferee to the same benefits and rights under this Agreement, as those held by the transferor. Milan and the Rights Agent may each require payment of a sum sufficient to cover any stamp or other transfer tax or governmental charge that is imposed in connection with (and would not have been imposed but for) any such registration of transfer. No transfer of CVRs shall be valid until registered in the CVR Register and any transfer not duly registered in the CVR Register shall be void.

(d) A Holder may make a written request to the Rights Agent to change such Holder’s address of record in the CVR Register. Such written request must be duly executed by such Holder. Upon receipt of such written notice, the Rights Agent shall promptly record the change of address in the CVR Register.

For the avoidance of doubt, each of the requirements of the TIGIT Milestone must be fully satisfied for the TIGIT Milestone to be considered to be attained, and (i) Milan shall have no further liability in respect of the TIGIT Milestone Payment upon delivery of the Milan Depositary Shares in accordance with this Section 2.4(a) and the satisfaction of each of Milan’s obligations set forth in this Section 2.4(a) and (ii) the Holders will not be entitled to, and Milan will not be liable for, any TIGIT Milestone Payment in the event of any partial satisfaction of the TIGIT Milestone.

(b) If a NAVI Milestone occurs at any time prior to the expiration of the Second NAVI Period and on each such occurrence, then, on or prior to the Milestone Payment Date relating thereto, Milan, or a Person nominated by Milan (with written notice thereof from Milan to the Rights Agent), as the case may be, will deliver to the Rights Agent (i) a certificate (each such certificate, a “NAVI Milestone Achievement Certificate”) certifying the date of satisfaction of the applicable NAVI Milestone and that the Holders are entitled to receive a NAVI Milestone Payment, and (ii) the applicable NAVI Milestone Payment, by wire transfer of immediately available funds to an account designated by the Rights Agent. Upon receipt of the wire transfer referred to in the foregoing sentence, the Rights Agent will promptly (and in any event, within ten (10) Business Days) pay, by check mailed, first-class postage prepaid, to the address of each Holder set forth in the CVR Register at such time or by other method of delivery as specified by the applicable Holder in writing to the Rights Agent, an amount in cash equal to the product determined by multiplying (A) the quotient determined by dividing (x) the applicable NAVI Milestone Payment by (y) the total number of CVRs registered in the CVR Register at such time, by (B) the number of CVRs registered to such Holder in the CVR Register at such time. For the avoidance of doubt, each of the requirements of each NAVI Milestone must be fully satisfied for such NAVI Milestone to be considered to be attained, and (i) Milan shall have no further liability in respect of the NAVI Milestone Payment upon delivery of the relevant funds in accordance with this Section 2.4(b) and (ii) the Holders will not be entitled to, and Milan will not be liable for, any NAVI Milestone Payment in the event of any partial satisfaction of the requirements relating to such NAVI Milestone.

(c) If a Milestone is not attained at any time prior to the expiration of the applicable Milestone Period then, on or before the date that is ten (10) Business Days after the end of such Milestone Period, Milan will deliver to the Rights Agent an Officer’s Certificate (the “Milestone Non-Achievement Certificate”) certifying that the applicable Milestone has not occurred and that Milan has complied in all material respects with its obligations under this Agreement. The Rights Agent will promptly (and in any event, within ten (10) Business Days after receipt) deliver a copy of such Milestone Non-Achievement Certificate to the Holders. The Rights Agent will deliver to Milan a certificate certifying the date of delivery of such certificate to the Holders.

(d) If the Rights Agent does not receive from the Majority of Holders a written objection to a Milestone Non-Achievement Certificate within thirty (30) Business Days after the date of delivery of such Milestone Non-Achievement Certificate by the Rights Agent to the Holders, the Holders will be deemed to have accepted such Milestone Non-Achievement Certificate, and Milan and its Subsidiaries will have no further obligation or liability with respect to the determination of the applicable Milestone Payment.

(e) Except to the extent any portion of any Milestone Payment is required to be treated as imputed interest pursuant to applicable Law, the parties hereto agree to treat the CVRs and all Milestone Payments for all Tax purposes as consideration for shares of Company Common Stock and Company Options pursuant to the Merger Agreement, and the parties hereto will not take any position to the contrary on any Tax Return or for other Tax purposes except as required by applicable Law.

(f) Milan and the Rights Agent will be entitled to deduct and withhold, or cause to be deducted and withheld, from any Milestone Payment otherwise payable pursuant to this Agreement, such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of applicable Law relating to Taxes. To the extent that amounts are so deducted and withheld, such deducted and withheld amounts will be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction and withholding was made. Prior to making any such Tax deductions or withholdings or causing any such Tax deductions or withholdings to be made with respect to any Holder, the Rights Agent will, to the extent reasonably practicable, provide notice to the Holder of such potential Tax deduction or withholding and a reasonable opportunity for the Holder to provide any necessary Tax forms in order to avoid or reduce such withholding amounts; provided that the time period for payment of a Milestone Payment by the Rights Agent set forth in Section 2.4(a) or Section 2.4(b) will be extended by a period equal to any delay caused by the Holder providing such forms, provided, further, that in no event shall such period be extended for more than ten (10) Business Days, unless otherwise requested by the Holder for the purpose of delivering such forms and agreed to by the Rights Agent.

(g) Any portion of a Milestone Payment that remains undistributed to the Holders six (6) months after the Milestone Payment Date (including by means of uncashed checks or invalid addresses on the CVR Register) will be delivered by the Rights Agent to Milan or a person nominated in writing by Milan (with written notice thereof from Milan to the Rights Agent), and any Holder will thereafter look only to Milan for payment of such Milestone Payment (which shall be without interest).

(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. Neither Milan nor the Rights Agent will be liable to any Person in respect of a Milestone Payment delivered to a public official pursuant to any applicable abandoned property, escheat or similar legal requirement under applicable Law.

Section 2.5 No Voting, Dividends or Interest; No Equity or Ownership Interest.

(a) CVRs will not have any voting or dividend rights, and interest will not accrue on any amounts payable in respect of CVRs.

(b) CVRs will not represent any equity or ownership interest in Milan or any of its Subsidiaries or in the Surviving Corporation. The sole right of the Holders to receive property hereunder is the right to receive Milestone Payments, if any, in accordance with the terms hereof. It is hereby acknowledged and agreed that a CVR shall not constitute a security of Milan or any of its Subsidiaries or of the Surviving Corporation.

Section 2.6 Ability to Abandon CVR.

A Holder may at any time, at such Holder’s option, abandon all of such Holder’s remaining rights represented by CVRs by transferring such CVR to Milan or a person nominated in writing by Milan (with written notice thereof from Milan to the Rights Agent) without consideration in compensation therefor, and such rights will be cancelled, with the Rights Agent being promptly notified in writing by Milan of such transfer and cancellation. Nothing in this Agreement is intended to prohibit Milan or its Affiliates from offering to acquire or acquiring CVRs, in private transactions or otherwise, for consideration in its sole discretion.

Section 2.7 Share Consideration Cap.

The number of Milan Ordinary Shares underlying the Milan Depositary Shares to be issued pursuant to this CVR Agreement, when aggregated with the number of Milan Ordinary Shares underlying the Milan Depositary Shares issued as Share Consideration pursuant to Section 1.5(a)(ii) of the Merger Agreement shall not, in the aggregate, exceed the Share Consideration Cap, and, if the aggregate number of Milan Depositary Shares to be issued pursuant to Section 2.4(a) of this 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 (collectively, the “Total Share Consideration”), otherwise exceed the Share Consideration Cap, then the number of Milan Depositary Shares to be issued pursuant to this CVR Agreement shall be appropriately reduced so that the Total Share Consideration does not exceed the Share Consideration Cap. For the avoidance of doubt, the Share Consideration Cap shall not operate to limit or restrict any NAVI Milestone Payment which is or becomes payable pursuant to this Agreement.

Section 2.8 Cash Consideration Cap.

The aggregate principal amount of all cash payments made to Holders by Milan as NAVI Milestone Payments pursuant to this CVR Agreement shall in no case exceed the Cash Consideration Cap. If the aggregate principal amount to be paid to Holders by Milan pursuant to Section 2.4(b) of this CVR Agreement would, together with the aggregate principal amount of any prior such cash payments, otherwise exceed the Cash Consideration Cap, then the applicable NAVI Milestone Payment shall be appropriately reduced so that the aggregate principal amount of such payment, together with any prior such cash payments, does not exceed the Cash Consideration Cap.

Section 2.9 Fractional Entitlements.

No fractional Milan Ordinary Shares or Milan Depositary Shares shall be issued in connection with the TIGIT Milestone Payment, and no certificates or scrip for any such fractional shares shall be issued. Any fractional share resulting from the application of the TIGIT Ratio shall be rounded down to the nearest whole share, with no cash being paid for any fractional share eliminated by such rounding.

ARTICLE 3

Anything to the contrary notwithstanding, in no event will the Rights Agent be liable for special, punitive, indirect, incidental or consequential loss or damages of any kind whatsoever (including, without limitation, lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damages, and regardless of the form of action.

(d) The Rights Agent may engage and consult with counsel of its selection, and the advice or opinion of such counsel will, in the absence of bad faith, gross negligence or willful misconduct on the part of the Rights Agent, be full and complete authorization and protection in respect of any action taken or not taken by the Rights Agent in reliance thereon.

(e) Any permissive rights of the Rights Agent hereunder will not be construed as a duty.

(i) No provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers if it believes that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

(j) The Rights Agent will not be deemed to have knowledge of any event of which it was supposed to receive notice hereunder but has not received written notice of such event, and the Rights Agent will not incur any liability for failing to take action in connection therewith, in each case, unless and until it has received such notice in writing.
