Section 3.3. Tag-Along Rights.

(a) Subject to Section 3.3(h), (x) if any Initiating Tag-Along Seller proposes to transfer all or a portion of their DTI Securities to any Person (other than to a Permitted Transferee of such Initiating Tag-Along Seller) or (y) a Sale Transaction is entered into by the MD Stockholders that either is a Qualified Sale Transaction or has been approved by the SLP Stockholders (each of the transfers in the foregoing clauses (x) and (y), a “Tag-Along Sale”), then the Initiating Tag-Along Seller shall give, or direct the Company to give and the Company shall so promptly give, written notice (a “Tag-Along Sale Notice”) of such proposed transfer to all Eligible Tag-Along Sellers with respect to such Tag-Along Sale at least fifteen (15) days prior to each of the consummation of such proposed transfer and the delivery of a Tag-Along Sale Notice setting forth (i) the number and type of each class of DTI Securities proposed to be transferred, (ii) the consideration to be received for such DTI Securities by such Initiating Tag-Along Seller, including (in the case of any transfer by the MD Stockholders) any Additional Consideration received, (iii) the identity of the purchaser (the “Tag-Along Buyer”), (iv) a copy of all definitive documents relating to such Tag-Along Sale, including all documents that the Eligible Tag-Along Seller would be required to execute in order to participate in such Tag-Along Sale and all other agreements or documents referred to, or referenced, therein, (v) a detailed summary of all material terms and conditions of the proposed transfer, (vi) the fraction, expressed as a percentage, determined by dividing the number of DTI Securities to be purchased from the Initiating Tag-Along Seller and its Permitted Transferees by the total number of DTI Securities held by the Initiating Tag-Along Seller and its Permitted Transferees (the “Tag-Along Sale Percentage”) and (vii) an invitation to each Eligible Tag-Along Seller to irrevocably agree to include in the Tag-Along Sale up to a number of DTI Securities held by such Eligible Tag-Along Seller equal to the product of the total number of DTI Securities held by such Eligible Tag-Along Seller multiplied by the Tag-Along Sale Percentage, subject to adjustment pursuant to the Tag-Along Sale Priority and the Tag-Along Sale Proration as contemplated in Section 3.3(c) (such amount of DTI Securities with respect to each Eligible Tag-Along Seller, such Eligible Tag-Along Seller’s “Tag-Along Shares”). In the event that any MD Related Party directly or indirectly receives any compensation or other consideration or benefit arising out of or in connection with the applicable Tag-Along Sale (other than any bona fide cash and/or equity compensation (whether in the form of an initial equity grant or otherwise) for service as an executive officer of the acquiring or surviving company or any of their Subsidiaries or, with respect to MD Related Parties, any bona fide commercial arrangement that is not a “Related Party Transaction” (as defined in the MD Stockholders Agreement) because of the proviso of the definition thereof between an MD Related Party and the proposed Tag-Along Buyer or any of its Affiliates which commercial arrangement has been binding and in full force and effect (or, in the absence of a binding legal arrangement, to the extent a course of dealing has been in place) for at

16

least twelve (12) months prior to the date that the Tag-Along Sale Notice is provided to the Eligible Tag-Along Seller) pursuant to any non-competition, non-solicitation, no-hire, or other arrangement separate from the transfer of the DTI Securities of the Company (“Additional Consideration”), the value of such Additional Consideration (as reasonably determined by the Board of the Company, subject to the consent of the SLP Stockholders not to be unreasonably withheld, conditioned or delayed) shall be deemed to have been part of the consideration paid or payable to the MD Stockholders in respect of their DTI Securities in such Tag-Along Sale and shall be reflected in the amount offered by the Tag-Along Buyer set forth in the applicable Tag-Along Sale Notice. In the event that more than one MD Stockholder or more than one SLP Stockholder, as the case may be, proposes to execute a Tag-Along Sale as an Initiating Tag-Along Seller, then all such transferring MD Stockholders and/or SLP Stockholders, as the case may be, shall be treated as the Initiating Tag-Along Seller, and the DTI Securities held and to be transferred by such MD Stockholders or SLP Stockholders, as the case may be, shall be aggregated as set forth in Section 5.16, including for purposes of calculating the applicable Tag-Along Sale Percentage; provided, that if the group of stockholders treated as the Initiating Tag-Along Seller pursuant to this sentence includes any SLP Stockholders, then the Tag-Along Sale Percentage applicable to the New Class C Stockholders shall be calculated as if the SLP Stockholders are the only stockholders treated as the Initiating Tag-Along Seller. Notwithstanding anything in this Section 3.3 to the contrary, but subject to Section 3.3(c), if the Initiating Tag-Along Seller is transferring Common Stock or vested in-the-money Company Stock Options in such Tag-Along Sale, each of the Eligible Tag-Along Sellers shall be entitled to transfer the same proportion of DTI Securities held by such Eligible Tag-Along Seller as the proportion of the Initiating Tag-Along Seller’s Common Stock and vested in-the-money Company Stock Options relative to the Initiating Tag-Along Seller’s total number of such DTI Securities that are being sold by the Initiating Tag-Along Seller in such Tag-Along Sale (with each vested in-the-money Company Stock Option counting as a share of Common Stock for purposes of the foregoing calculation).

(b) Upon delivery of a Tag-Along Sale Notice, each Eligible Tag-Along Seller may elect to include all or a portion of such Eligible Tag-Along Seller’s Tag-Along Shares in such Tag-Along Sale (Eligible Tag-Along Sellers who make such an election being an “Electing Tag-Along Seller” and, together with the Initiating Tag-Along Seller and all other Persons (other than any Affiliates of the Initiating Tag-Along Seller) who otherwise are transferring, or have exercised a contractual or other right to transfer, DTI Securities in connection with such Tag-Along Sale, the “Tag-Along Sellers”), at the same price per share equivalent of Common Stock and pursuant to the same terms and conditions as agreed to by the Initiating Tag-Along Seller and otherwise in accordance with this Section 3.3, by sending an irrevocable written notice (a “Tag-Along Participation Notice”) to the Initiating Tag-Along Seller within fifteen (15) days of the date the Tag-Along Sale Notice is received by such Eligible Tag-Along Seller, indicating such Electing Tag-Along Seller’s irrevocable election, subject to Section 3.3(d), to include its Tag-Along Shares in the Tag-Along Sale and setting forth the number of Eligible Tag-Along Seller’s Tag-Along Shares it elects to include. Following such fifteen (15) day period, each Electing Tag-Along Seller that has delivered a Tag-Along Participation Notice shall be entitled to sell to such proposed transferee on the same terms and conditions as and, concurrently with, the other Electing Tag-Along Sellers and the Initiating Tag-Along Seller, such Electing Tag-Along Seller’s Tag-Along Shares it elects to include, which terms and conditions have been set forth in the Tag-Along Sale Notice, subject to the Tag-Along

17

Sale Priority and the Tag-Along Sale Proration as contemplated in Section 3.3(c). Each Eligible Tag-Along Seller who does not deliver a Tag-Along Participation Notice within such fifteen (15) day period shall have waived and be deemed to have waived all of such Eligible Tag-Along Seller’s rights with respect to such Tag-Along Sale. For the avoidance of doubt, it is understood that in order to be entitled to exercise its right to include Tag-Along Shares in a Tag-Along Sale pursuant to this Section 3.3, each Electing Tag-Along Seller must agree to make the same representations and warranties, covenants, indemnities and agreements to the Tag-Along Buyer as made by the Initiating Tag-Along Seller and any Electing Tag-Along Seller in connection with the Tag-Along Sale (and shall be subject to the same escrow or other holdback arrangements as such Persons so long as such escrows or other holdbacks are proportionately based on the amount of consideration received for the sale of DTI Securities in such Tag-Along Sale transaction); provided, that:

(i) each Electing Tag-Along Seller shall be entitled to receive its pro rata portion (based on the relative amount (and taking into account the per share equivalent of Common Stock) of DTI Securities sold in such Tag-Along Sale transaction) of any deferred consideration or indemnification payments relating to such Tag-Along Sale (provided, however, that, with respect to any unexercised Company Stock Options proposed to be transferred in such Tag-Along Sale by any Tag-Along Seller, the per share consideration in respect thereof shall be reduced by the exercise price of such options or, if required pursuant to the terms of such options or such Tag-Along Sale, such Tag-Along Seller must exercise the relevant option and transfer the relevant shares of Common Stock (rather than the option) (in each case, net of any amounts required to be withheld by the Company in connection with such exercise));

(ii) the aggregate amount of liability of each Electing Tag-Along Seller shall not exceed the proceeds received by such Electing Tag-Along Seller in such Tag-Along Sale;

(iii) all indemnification obligations (other than with respect to the matters referenced in Section 3.3(b)(iv)) shall be on a several and not joint basis to the Tag-Along Sellers pro rata (based on the amount of consideration received by each Tag-Along Seller in the Tag-Along Sale transaction);

(iv) no Electing Tag-Along Seller shall be responsible for any indemnification obligations and/or liabilities (including through escrow or hold back arrangements) for (A) breaches or inaccuracies of representations and warranties made with respect to any other Tag-Along Seller’s (1) ownership of and title to DTI Securities, (2) organization and authority or (3) conflicts and consents and any other matter concerning such other Person and/or (B) breaches of any covenant specifically relating to any other Tag-Along Seller; and

(v) no Stockholders that have elected to be an Electing Tag-Along Seller shall be required in connection with such Tag-Along Sale transaction to agree to (A) any employee, customer or other non-solicitation, no-hire or other similar provision, (B) any non-competition or similar restrictive covenant and/or (C) any term that purports to bind any portfolio company or investment of any Electing Tag-Along Seller or any of their respective Affiliates.

18

(c) Notwithstanding anything in this Section 3.3 to the contrary, if the Initiating Tag-Along Seller (including, for the avoidance of doubt, any of their Permitted Transferees) seeks to transfer Common Stock representing a majority of the Common Stock beneficially owned by the MD Stockholders immediately following the Original Closing, then the number of Tag-Along Shares that an Eligible Tag-Along Seller may include in any Tag-Along Sale pursuant to this Section 3.3 shall be an amount equal to 100% of the equity securities in the Company, Dell and their respective Subsidiaries held by such Eligible Tag-Along Seller (such right, the “Tag-Along Sale Priority”). Further, in the event that Stockholders having the right to participate in a Tag-Along Sale (including the Initiating Tag-Along Seller, the “Participating Sellers”) have elected to include more DTI Securities in the aggregate than the Tag-Along Buyer is willing to purchase (the “Tag-Along Demand”), the number of DTI Securities permitted to be sold by the Participating Sellers shall be reduced such that each Tag-Along Seller is permitted to sell only its pro rata share of the Tag-Along Demand (in proportion to the number of DTI Securities held by each Participating Seller) (the “Tag-Along Sale Proration”); provided, that, in a Tag-Along Sale subject to Tag-Along Sale Priority rights, the number of DTI Securities to be sold by Participating Sellers with Tag-Along Sale Priority shall not be reduced.

(d) Notwithstanding the delivery of any Tag-Along Sale Notice, all determinations as to whether to complete any Tag-Along Sale and as to the timing, manner, price and, subject to Section 3.3(b)(i) through (v), other terms and conditions of any such Tag-Along Sale shall be at the sole discretion of the Initiating Tag-Along Seller, and none of the Initiating Tag-Along Seller, its Affiliates and their respective Representatives shall have any liability to any Electing Tag-Along Seller arising from, relating to or in connection with the pursuit, consummation, postponement, abandonment or terms and conditions of any proposed Tag-Along Sale except to the extent such Initiating Tag-Along Seller failed to comply with the provisions of this Section 3.3; provided, that (i) if the Initiating Tag-Along Seller agrees to amend, restate, modify or supplement the terms and/or conditions of the Tag-Along Sale after such time that any Stockholder has elected to be an Electing Tag-Along Seller in accordance with the terms of this Section 3.3, the Initiating Tag-Along Seller shall promptly notify the Company and each Electing Tag-Along Seller of such amendment, restatement, modification and/or supplement and (ii) each such Electing Tag-Along Seller shall have the right to withdraw its Tag-Along Participation Notice by delivering written notice of such withdrawal to the Initiating Tag-Along Seller within five (5) Business Days of the date of receipt of such notice from the Initiating Tag-Along Seller.

(e) Notwithstanding anything in this Section 3.3 to the contrary, this Section 3.3 shall not apply to (i) any transfers of DTI Securities to a Permitted Transferee of the transferring Stockholder and/or (ii) any transfer of Common Stock in a registered public offering (whether in a Demand Registration, Piggyback Registration, Marketed Underwritten Shelf Take-Down (each as defined in the Registration Rights Agreement) or otherwise), it being understood that participation rights in connection with transfers of Common Stock in a registered public offering (whether in a Demand Registration, Piggyback Registration, Marketed Underwritten Shelf Take-Down (each as defined in the Registration Rights Agreement) or otherwise) shall be governed by the terms of the Registration Rights Agreement.

19

(f) All reasonable and documented out-of-pocket costs and expenses incurred by the Company, its Subsidiaries and/or the Tag-Along Sellers in connection with such Tag-Along Sale shall be allocated and borne on a pro rata basis by each Tag-Along Seller in accordance with the amount of consideration otherwise received by each Tag-Along Seller in such Tag-Along Sale. For the avoidance of doubt, it is understood that this Section 3.3(f) shall not prevent any Tag-Along Sale to be structured in a manner such that some or all of the such costs and expenses result in a pro rata reduction in the consideration received by the Tag-Along Sellers in such Tag-Along Sale.

(g) Notwithstanding anything herein to the contrary, if the Initiating Tag-Along Seller has not completed the proposed Tag-Along Sale within one hundred twenty (120) days following delivery of the Tag-Along Sale Notice in accordance with this Section 3.3, the Initiating Tag-Along Seller may not then effect such proposed Tag-Along Sale without again complying with the provisions of this Section 3.3; provided, that if such proposed Tag-Along Sale is subject to, and conditioned on, one or more prior regulatory approvals, then such one hundred twenty (120) day period shall be extended solely to the extent necessary until no later than the expiration of ten (10) days after all such approvals shall have been received.

(h) The “tag-along” rights described in this Section 3.3 shall survive the Merger (and shall be exercisable by any Stockholder) in respect of a single or series of related transfers of DTI Securities by the MD Stockholders equal to 10% or more of the then outstanding Common Stock to the same Person or “group” (within the meaning of Section 13(d) of the Exchange Act) (other than a Permitted Transferee of the MD Stockholders) and shall automatically terminate upon the earlier of (i) the 18-month anniversary of the Closing Date and (ii) such time following the Closing that the MD Stockholders no longer beneficially own Common Stock representing a majority of the Common Stock beneficially owned by the MD Stockholders immediately following the Original Closing Date; provided, that in addition to any other applicable provisions in this Section 3.3 (including the Tag-Along Sale Priority and the Tag-Along Sale Proration), such transfer of DTI Securities shall also be subject to the Priority Sell-Down pursuant to the Registration Rights Agreement; provided, further, that any registered offering of DTI Securities shall be governed by the terms of the Registration Rights Agreement.

(i) Notwithstanding the foregoing, (1) it is understood that a transfer of limited partnership interests, limited liability company interests or similar interests in any of the Sponsor Stockholders, any other private equity fund or any parent entity with respect to any such Sponsor Stockholder or private equity fund shall not constitute a transfer for purposes of this Agreement so long as there is no change of control of such entity, and (2) any conversion of Class A Common Stock, Class B Common Stock or Class D Common Stock to Class C Common Stock as contemplated by the Company’s Fifth Amended and Restated Certificate of Incorporation shall not be deemed a “transfer” hereunder.

20

Section 3.4. Black-Out Periods.

(a) Each New Class C Stockholder agrees not to (1) offer for sale, sell, pledge, hypothecate, transfer, make any short sale of, loan, grant any option or right to purchase of or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any DTI Securities (including DTI Securities that may be deemed to be beneficially owned by the Participating Class C Stockholder in accordance with the rules and regulations of the SEC) or securities convertible into or exercisable or exchangeable for DTI Securities, (2) enter into any swap, hedging arrangement or other derivatives transaction with respect to any DTI Securities (including DTI Securities that may be deemed to be beneficially owned by the Participating Class C Stockholder in accordance with the rules and regulations of the SEC) or securities convertible into or exercisable or exchangeable for DTI Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of DTI Securities, in cash or otherwise or (3) publicly disclose the intention to do any of the foregoing, in the case of each of the foregoing clauses (1) through (3), during the period beginning on the Closing Date and ending one hundred eighty (180) days thereafter; provided that each New Class C Stockholder may transfer DTI Securities to a Permitted Transferee thereof so long as any such Permitted Transferee, that is not a party to this Agreement executes and delivers to the Company a Joinder Agreement pursuant to which such Person agrees to be bound by and comply with the provisions of, this Agreement (including, for the avoidance of doubt, this Section 3.4). For the avoidance of doubt, any transfer of DTI Securities by the New Class C Stockholders permitted pursuant to the immediately foregoing proviso shall be subject to all other applicable provisions of this Agreement, including, without limitation, Section 3.1 and Section 3.2.

(b) Notwithstanding anything to the contrary in Section 3.4(a), if any Sponsor Stockholder or MSD Partners Stockholder is granted a discretionary release or waiver by the Company from the transfer restrictions applicable to such person pursuant to Section 2.14(a) of the Registration Rights Agreement prior to the 181st day following the Closing Date, then each New Class C Stockholder shall (without duplication of any lock-up release provisions applicable to such New Class C Stockholder in the Registration Rights Agreement or any other agreement) be entitled to transfer a number of DTI Securities equal to the product of (x) the maximum percentage (after applying the provisions of Section 5.16) of DTI Securities held by any Sponsor Stockholder or MSD Partners Stockholder being released from Section 2.14(a) of the Registration Rights Agreement pursuant to such discretionary release or waiver multiplied by (y) the total number of DTI Securities held by such New Class C Stockholder. In addition, a New Class C Stockholder may be released, in whole or in part, from the restrictions imposed by Section 3.4(a) with, and to the extent provided by, the written consent of the Company (which Company consent shall require approval by the Special Committee).

(c) In the event of an Underwritten Offering in which one or more New Class C Stockholders are participating (the “Participating Class C Stockholders”), each of the Participating Class C Stockholders agrees if requested by the Company or the managing underwriter or underwriters in such Underwritten Offering or if requested by the Company, not to (1) offer for sale, sell, pledge, hypothecate, transfer, make any short sale of, loan, grant any option or right to purchase of or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any DTI Securities (including DTI Securities that may be deemed to be beneficially owned by the Participating Class C Stockholder in accordance with the rules and regulations of

21

the SEC) or securities convertible into or exercisable or exchangeable for DTI Securities, (2) enter into any swap, hedging arrangement or other derivatives transaction with respect to any DTI Securities (including DTI Securities that may be deemed to be beneficially owned by the Participating Class C Stockholder in accordance with the rules and regulations of the SEC) or securities convertible into or exercisable or exchangeable for DTI Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of DTI Securities, in cash or otherwise or (3) publicly disclose the intention to do any of the foregoing, in the case of each of the foregoing clauses (1) through (3), during the period beginning seven (7) days before such Underwritten Offering, and ending ninety (90) days thereafter. If requested by the managing underwriter or underwriters of any such Underwritten Offering, each Participating Class C Stockholder shall execute a customary agreement reflecting its agreement set forth in this Section 3.4(c).

ARTICLE V

MISCELLANEOUS

Section 5.1. Entire Agreement. This Agreement (together with the applicable Subscription Agreement and the Registration Rights Agreement) constitutes the entire understanding and agreement between the parties with respect to the DTI Securities owned by the New Class C Stockholders and supersedes and replaces any prior understanding, agreement or statement of intent, in each case, written or oral, of any and every nature with respect thereto; provided that, for the avoidance of doubt, the Original Agreement shall continue to have full force and effect with respect to matters addressed therein for periods prior to the effectiveness of this Agreement. In the event of any inconsistency between this Agreement and any document executed or delivered to effect the purposes of this Agreement, including the Organizational Documents of any Person, this Agreement shall govern as among the parties hereto. Each of the parties hereto shall exercise all voting and other rights and powers available to it so as to give effect to the provisions of this Agreement and, if necessary, to procure (so far as it is able to do so) any required amendment to the Company’s and/or its Subsidiaries’ Organizational Documents, in order to cure any such inconsistency.

Section 5.2. Specific Performance. The parties hereto agree that the obligations imposed on them in this Agreement are special, unique and of an extraordinary character, and that, in the event of breach by any party, damages would not be an adequate remedy and each of the other parties shall be entitled to specific performance and injunctive and other equitable relief in addition to any other remedy to which it may be entitled, at law or in equity. The parties hereto further agree to waive any requirement for the securing or posting of any bond in connection with the obtaining of any such injunctive or other equitable relief.

24

Section 5.3. Governing Law. This Agreement and all claims or causes of action (whether in tort, contract or otherwise) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement) shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws.

Section 5.4. Submissions to Jurisdictions; WAIVER OF JURY TRIAL.

(a) Each of the parties hereto hereby irrevocably acknowledges and consents that any legal action or proceeding brought with respect to this Agreement or any of the obligations arising under or relating to this Agreement shall be brought and determined exclusively in the Court of Chancery in the State of Delaware (or, only if the Court of Chancery in the State of Delaware declines to accept jurisdiction over a particular matter, any Federal court of the United States of America sitting in the State of Delaware), and each of the parties hereto hereby irrevocably submits to and accepts with regard to any such action or proceeding, for itself and in respect of its property, generally and unconditionally, the exclusive jurisdiction of the Court of Chancery in the State of Delaware (or, only if the Court of Chancery in the State of Delaware declines to accept jurisdiction over a particular matter, any Federal court of the United States of America sitting in the State of Delaware). Each party hereby further irrevocably waives any claim that the Court of Chancery in the State of Delaware (or, only if the Court of Chancery in the State of Delaware declines to accept jurisdiction over a particular matter, any Federal court of the United States of America sitting in the State of Delaware) lacks jurisdiction over such party, and agrees not to plead or claim, in any legal action or proceeding with respect to this Agreement or the transactions contemplated hereby brought in the Court of Chancery in the State of Delaware (or, only if the Court of Chancery in the State of Delaware declines to accept jurisdiction over a particular matter, any Federal court of the United States of America sitting in the State of Delaware), that any such court lacks jurisdiction over such party.

(b) Each party irrevocably consents to the service of process in any legal action or proceeding brought with respect to this Agreement or any of the obligations arising under or relating to this Agreement by the mailing of copies thereof by registered or certified mail, postage prepaid, to such party, at its address for notices as provided in Section 5.13 of this Agreement, such service to become effective ten (10) days after such mailing. Each party hereby irrevocably waives any objection to such service of process and further irrevocably waives and agrees not to plead or claim in any action or proceeding commenced hereunder or under any other documents contemplated hereby, that service of process was in any way invalid or ineffective. Subject to Section 5.4(c), the foregoing shall not limit the rights of any party to serve process in any other manner permitted by applicable law. The foregoing consents to jurisdiction shall not constitute general consents to service of process in the State of Delaware for any purpose except as provided above and shall not be deemed to confer rights on any Person other than the respective parties to this Agreement.

25

(c) Each of the parties hereto hereby waives any right it may have under the laws of any jurisdiction to commence by publication any legal action or proceeding with respect to this Agreement or any of the obligations under or relating to this Agreement. To the fullest extent permitted by applicable law, each of the parties hereto hereby irrevocably waives the objection which it may now or hereafter have to the laying of the venue of any suit, action or proceeding with respect to this Agreement or any of the obligations arising under or relating to this Agreement in the Court of Chancery in the State of Delaware (or, only if the Court of Chancery in the State of Delaware declines to accept jurisdiction over a particular matter, any Federal court of the United States of America sitting in the State of Delaware), and hereby further irrevocably waives and agrees not to plead or claim that the Court of Chancery in the State of Delaware (or, only if the Court of Chancery in the State of Delaware declines to accept jurisdiction over a particular matter, any Federal court of the United States of America sitting in the State of Delaware) is not a convenient forum for any such suit, action or proceeding.

(d) The parties hereto agree that any judgment obtained by any party hereto or its successors or assigns in any action, suit or proceeding referred to above may, in the discretion of such party (or its successors or assigns), be enforced in any jurisdiction, to the extent permitted by applicable law.

(e) EACH OF THE PARTIES HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY SUIT, ACTION OR PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH OF THE PARTIES (I) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ANY SUIT, ACTION OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER AND (II) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS Section 5.4(e).

Section 5.5. Obligations. All obligations hereunder shall be satisfied in full without set-off, defense or counterclaim.

Section 5.6. Consents, Approvals and Actions.

(a) MD Stockholders. All actions required to be taken by, or approvals or consents of, the MD Stockholders under this Agreement shall be taken by consent or approval by, or agreement of, MD or his permitted assignee; provided, that upon the occurrence and during the continuation of a Disabling Event, such approval or consent shall be taken by consent or approval by, or agreement of, the holders of a majority of the DTI Securities held by the MD Stockholders, and in each case, such consent, approval or agreement shall constitute the necessary action, approval or consent by the MD Stockholders.

26

(b) SLP Stockholders. All actions required to be taken by, or approvals or consents of, the SLP Stockholders under this Agreement shall be taken by consent or approval by, or agreement of, the holders of a majority of the DTI Securities held by the SLP Stockholders, and in each case, such consent, approval or agreement shall constitute the necessary action, approval or consent by the SLP Stockholders.

(c) New Class C Stockholders. All actions required to be taken by, or approvals or consents of, the New Class C Stockholders under this Agreement shall be taken by consent or approval by, or agreement of, the holders of a majority of the DTI Securities held by the New Class C Stockholders, and such consent, approval or agreement shall constitute the necessary action, approval or consent by the New Class C Stockholders.

Section 5.7. Amendment; Waiver.

(a) Except as set forth below, any amendment or modification of any provision of this Agreement shall require the prior written approval of the Company; provided, that (i) if any such amendment or modification adversely affects the MD Stockholders, it shall require the prior written consent of the holders of a majority of the DTI Securities held by the MD Stockholders in the aggregate, (ii) if any such amendment or modification adversely affects the SLP Stockholders, it shall require the prior written consent of the holders of a majority of the DTI Securities held by the SLP Stockholders in the aggregate and (iii) if the express terms of any such amendment or modification disproportionately and adversely affect one or more New Class C Stockholders relative to the Sponsor Stockholders or any other New Class C Stockholder, it shall require the prior written consent of the holders of a majority of the DTI Securities held by such affected New Class C Stockholders in the aggregate. Notwithstanding the foregoing, (i) the foregoing proviso shall not apply with respect to in the case of New Class C Stockholders, amendments or modifications that do not apply to New Class C Stockholders, (ii) any addition of a transferee of DTI Securities or a recipient of DTI Securities as a party hereto pursuant to Section 3.1(a) shall not constitute an amendment or modification hereto and the applicable Joinder Agreement need be signed only by the Company and such transferee or recipient, and (iii) the Company shall promptly amend the books and records of the Company appropriately as and to the extent necessary to reflect the removal or addition of a New Class C Stockholder, any changes in the amount and/or type of DTI Securities beneficially owned by each New Class C Stockholder and/or the addition of a transferee of DTI Securities or a recipient of any DTI Securities, in each case, pursuant to and in accordance with the terms of this Agreement.

(b) Any failure by the Company or a Sponsor Stockholder at any time to enforce any of the provisions of this Agreement shall not be construed a waiver of such provision or any other provisions hereof. The waiver by the Company or a Sponsor Stockholder of a breach of any provision of this Agreement shall not operate or be construed as a further or continuing waiver of such breach or as a waiver of any other or subsequent breach. Except as otherwise expressly provided herein, no failure on the part of the Company or a Sponsor Stockholder to exercise, and no delay in exercising, any right, power or remedy hereunder, or otherwise available in respect hereof at law or in equity, shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by the Company or a Sponsor Stockholder preclude any other or further exercise thereof or the exercise of any other right, power or remedy.

27

Section 5.8. Assignment of Rights By New Class C Stockholders. No New Class C Stockholder may assign or transfer its rights under this Agreement except with the prior consent of the MD Stockholders and the SLP Stockholders; provided, that no such consent shall be required for any assignment or transfer of DTI Securities to a Permitted Transferee which complies with Section 3.2. Any purported assignment of rights or obligations under this Agreement in derogation of this Section 5.8 shall be null and void.

Section 5.9. Transfers to Permitted Transferees. Each MD Stockholder and SLP Stockholder agrees that it will not transfer any DTI Securities to any of its Permitted Transferees unless (i) such Permitted Transferee is already a party to this Agreement or (ii) at the time of such transfer such Permitted Transferee executes and delivers to the Company a Joinder Agreement in the form attached hereto as Annex A and becomes a party to this Agreement.

Section 5.10. Binding Effect. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the parties’ successors and permitted assigns.

Section 5.11. Third Party Beneficiaries. Except for Section 5.14 (which will be for the benefit of the Persons set forth therein, and any such Person will have the rights provided for therein), this Agreement does not create any rights, claims or benefits inuring to any Person that is not a party hereto, and it does not create or establish any third party beneficiary hereto.
