The Offer Notice shall constitute, for a period of 20 Business Days after the delivery of the Offer Notice, a binding, irrevocable and exclusive offer to sell to the DT Stockholder (or any Controlled Affiliate of the DT Stockholder designated by the DT Stockholder or as part of a “group” including the DT Stockholder as contemplated by Section 13d-5(b) of the Exchange Act) (the “Designated Transferee”) any or all of the ROFR MC Shares (i) in the case of a proposed Transfer that is not an Open Market Transfer, on the Offer Terms (at the purchase price per MC Share set forth therein); provided that if the Offer Terms provide for payment of any non-cash consideration, the DT Stockholder may elect to pay the purchase price in respect of such non-cash consideration in cash in an amount that is equal to the fair market value of such non-cash consideration described in the Offer Terms, as determined in good faith and mutually agreed by the MC Stockholder and the DT Stockholder (provided that, if the MC Stockholder and the DT Stockholder shall be unable to so mutually agree within 10 Business Days of the delivery of the Offer Notice, then either party may commence the valuation process described in Section 4(e) and the periods set forth in this Section 4(c) shall be tolled for, and such periods (or the remaining portion thereof) shall recommence only upon a final and binding determination of fair market value pursuant to, such valuation process); and (ii) in the case of a proposed Transfer that is an Open Market Transfer, at the Open Market Transfer Price; provided that, in each of clauses (i) and (ii), during such 20-Business-Day period, the MC Stockholder may not effect the proposed Transfer to the Proposed Transferee(s) or pursuant to any Open Market Transfer, as applicable (unless prior to the expiration thereof, the DT Stockholder provides written notice to the MC Stockholder that it is not electing to purchase the ROFR MC Shares). To accept such offer, an DT Stockholder shall deliver written notice (the “Acceptance Notice”) to the MC Stockholder on or prior to the end of such 20-Business-Day period setting forth (A) its binding acceptance of such offer, (B) the identity of the Designated Transferee, (C) the planned date for purchase of the ROFR MC Shares, which shall be a reasonable date within 120 days from the date of the Offer Notice (the “Planned Purchase Date”) and (D) the number of ROFR MC Shares to be purchased, whereupon the MC Stockholder will be obligated to sell, and the DT Stockholder will be obligated to purchase, such number of ROFR MC Shares in accordance with the Offer Terms or Open Market Transfer Price, as applicable, or such other terms and conditions as may be agreed between the MC Stockholder and the DT Stockholder. The closing of such purchase and sale shall occur on the Planned Purchase Date or at such time and place as the MC Stockholder and the DT Stockholder may agree, pursuant to an agreement containing reasonable and customary representations and warranties and other terms and conditions.

(d) Ability to Sell of the Transferring Stockholder. If (i) the DT Stockholder does not deliver an Acceptance Notice on or prior to the end of the 20-Business-Day period set

forth in Section 4(c), (ii) the DT Stockholder or the Designated Transferee, as the case may be, has not paid the full Transfer price for the ROFR MC Shares on such terms and conditions as may be agreed between the MC Stockholder and the DT Stockholder or, in the absence of such agreement, in accordance with the Offer Terms or the Open Market Transfer Price, as applicable, or (iii) the Acceptance Notice is not for all of the ROFR MC Shares, the MC Stockholder may, during the 120-day period immediately following the earlier of the end of such 20-Business-Day period and the delivery of the Acceptance Notice, Transfer the ROFR MC Shares (or the remaining ROFR MC Shares, in the event the Acceptance Notice is not for all the ROFR MC Shares) (A) if the proposed Transfer is an Open Market Transfer, pursuant to an Open Market Transfer, and (B) if the proposed Transfer is not an Open Market Transfer, to the Proposed Transferee(s) for no less than the purchase price per MC Share and the form of consideration, and on substantially similar terms and conditions of payment set forth in the Offer Terms, and otherwise on terms and conditions no more favorable to the Proposed Transferee(s) than the Offer Terms; provided that, if the MC Stockholder does not consummate the Transfer of the ROFR MC Shares in accordance with the foregoing within such 120-day period, any attempt to Transfer such ROFR MC Shares shall again be subject to the provisions of this Section 4.

(e) Valuation Process for Non-Cash Consideration. If any Offer Terms provide for payment of any non-cash consideration, then the MC Stockholder and the DT Stockholder shall negotiate in good faith to determine the fair market value of such non-cash consideration. If they are unable to agree on such fair market value within 10 Business Days of the delivery of the Offer Notice, then either the MC Stockholder or the DT Stockholder may commence the valuation process described in this Section 4(e) by providing written notice to the other party (such notice, a “Valuation Process Notice”). In the event a Valuation Process Notice is delivered, then within 10 Business Days of the delivery of the Valuation Process Notice, each of the MC Stockholder and the DT Stockholder shall appoint an internationally recognized investment banking firm (an “Appointed Bank”). Each of the MC Stockholder and the DT Stockholder shall instruct its Appointed Bank to determine, by no later than 20 Business Days after being appointed, its best estimate of the fair market value of the non-cash consideration, based on the customary methodologies that such Appointed Bank in its professional experience deem relevant to such a determination. On the 45th Business Day following delivery of the Valuation Process Notice or such earlier date as mutually agreed between the MC Stockholder and the DT Stockholder, each Appointed Bank shall present to the other party and its Appointed Bank its determination of the fair market value of such non-cash consideration. In the event the fair market values determined by the two Appointed Banks are within 10% of one another (determined by reference to the higher of the two), the fair market value shall be the average of those two estimates and such determination of the fair market value of the non-cash consideration shall be final and binding on the MC Stockholder and the DT Stockholder. In the event the fair market values determined by the two Appointed Banks are not within 10% of one another (determined by reference to the higher of the two), the Appointed Banks shall mutually select a third internationally recognized investment banking firm (the “Independent Bank”) to determine, by no later than 20 Business Days after being appointed, its best estimate of the fair market value of the non-cash consideration, based on the customary methodologies that such Independent Bank in its professional experience deem relevant to such a determination. The fair market value of the non-cash consideration shall then be determined by the Independent Bank, and such resulting determination shall be final and binding on the MC Stockholder and the DT Stockholder.

5. Right of First Refusal upon Foreclosure of Pledged MC Shares.

(a) Applicability. Until the ROFR Fall Away Date, the MC Stockholder shall not permit any Person to Transfer Pledged MC Shares in connection with any foreclosure without first complying with the procedures set forth in this Section 5, and the MC Stockholder shall not enter into any agreement or arrangement relating to a Pledge that is inconsistent with or would have the effect of circumventing the process and requirements set forth in this Section 5.

(b) Pledge ROFR Notice. In the event that a financial institution, brokerage firm or other Person that is the creditor in respect of any Obligation (such Person, including any agent, trustee or other Person acting in a similar capacity on behalf of such creditor, being a “Pledge Counterparty”) delivers a notice of event of default or a similar event or consequence pursuant to any agreement or arrangement relating to an Obligation secured by a Pledge of MC Shares, it shall concurrently deliver a written notice (the “Pledge ROFR Notice”) to the DT Stockholder, which notice shall include a copy of the notice delivered to the MC Stockholder and shall set forth (i) the number of Pledged MC Shares securing the Obligation that are in default or subject to a similar event or consequence (the “Pledge ROFR MC Shares”), (ii) the VWAP for the ten consecutive trading days immediately preceding the date of the Pledge ROFR Notice (the “Pledge ROFR MC Share Price”), (iii) the cure period applicable to such default, event or consequence and the earliest date and time following such cure period on which the Pledge Counterparty may foreclose on the Pledge ROFR MC Shares (together, the “Pledge ROFR Foreclosure Period”), which Pledge ROFR Foreclosure Period shall be no less than 2 Business Days, subject to notice, cure and information rights set forth in the agreements for such Pledged Shares and (iv) all other material terms and conditions related to the right of first refusal described in this Section 5.

(c) Option of the Pledge ROFR Offeree Stockholder. The Pledge ROFR Notice shall constitute, during the Pledge ROFR Foreclosure Period, a binding, irrevocable and exclusive offer to sell to the DT Stockholder (or any Controlled Affiliate of the DT Stockholder designated by the DT Stockholder or as part of a “group” including the DT Stockholder as contemplated by Section 13d-5(b) of the Exchange Act) (the “Designated Pledge ROFR Transferee”) any or all of the Pledge ROFR MC Shares on the terms and at the Pledge ROFR MC Share Price set forth in the Pledge ROFR Notice; provided that during the Pledge ROFR Foreclosure Period, the Pledge Counterparty may not effect a foreclosure sale or other Transfer of the Pledge ROFR MC Shares unless prior to the expiration thereof, the DT Stockholder provides written notice to the Pledge Counterparty that it has elected not to purchase the Pledge ROFR MC Shares. The DT Stockholder may elect to purchase any or all of the Pledge ROFR MC Shares by delivering a written notice (the “Pledge ROFR Acceptance Notice”) to both the MC Stockholder and the Pledge Counterparty on or prior to the end of the Pledge ROFR Foreclosure Period setting forth (i) its irrevocable acceptance of such offer, (ii) the identity of the Designated Pledge ROFR Transferee, (iii) its commitment to purchase the Pledge ROFR MC Shares on a date that is on or prior to the last day of the Pledge ROFR Foreclosure Period (the “Pledge ROFR Purchase Date”) and (iv) the number of Pledge ROFR MC Shares to be purchased, whereupon both the MC Stockholder and the Pledge Counterparty will be obligated to sell, and the DT Stockholder will be obligated to purchase, such number of Pledge ROFR MC Shares in accordance with the terms set forth in the Pledge ROFR Notice or such other terms and conditions as may be agreed between the DT Stockholder and the Pledge Counterparty. The

closing of such purchase and sale shall occur on the Pledge ROFR Purchase Date or at such time and place as the DT Stockholder and the Pledge Counterparty may agree, pursuant to an agreement containing reasonable and customary representations and warranties and other terms and conditions.
